摘要：

This study was performed to evaluate the oncological and reproductive outcomes of childbearing-age women treated with fertility-sparing surgery (FSS) for non-epithelial ovarian tumors in China. One hundred and forty eight non-epithelial ovarian tumor women treated with FSS between January 1, 2000 and August 31, 2015 from two medical centers in China were identified. Progression-free survival (PFS) was 88.5%, whereas overall survival (OS) was 93.9%. Univariate analysis suggested that delivery after treatment is related to PFS (P=0.023), whereas histology significantly influenced OS. Cox regression analysis suggested that only histology was associated with PFS and OS (P<0.05). Among the 129 women who completed adjuvant chemotherapy (ACT), none developed amenorrhea. Among the 44 women who desired pregnancy, 35 (79.5%) successfully had 51 gestations including 35 live births without birth defects. Non-epithelial ovarian tumors can achieve fulfilling prognosis after FSS and chemotherapy. Histology might be the only independent prognostic factor for PFS and OS. FSS followed by ACT appeared to have little or no effect on fertility. Meanwhile, postoperative pregnancy did not increase the PFS or OS. Use of gonadotropin-releasing hormone agonist was not beneficial for fertility.

《医学前沿（英文）》 2012年 第6卷 第3期   页码 317-321 doi: 10.1007/s11684-012-0203-9

摘要：

In order to find out the potential indicators predicting prognosis of malignant gastrointestinal stromal tumors (GISTs) after surgical resection, we collected clinical records of 80 patients with malignant GISTs. Tumor location, size, mitotic index, necrosis were compared with the prognosis of malignant GISTs by Kaplan-Meier method and log-rank test. After a median follow-up of 844 days (52–2 145), we found that as National Institutes of Health suggested, tumors with intermediate risk had more favorable prognosis than that with high risk. Their 3-year survival rate were 65.3% and 41.3%, respectively (P<0.001). Moreover, tumor size and mitotic index were associated with free survival. The 3-year survival rate for patients with tumor size≤10 cm and>10 cm were 62.3% and 41.8%, respectively (P = 0.002), Tumors with mitotic index≤5/50 HPF had a higher 3-year survival rate than tumors with mitotic index>5/50 HPF (67.1% versus 40.7%, P = 0.005). The presence of necrosis was directly related to the malignant behavior. The 3-year survival rate for presence and absence necrosis were 50.8% and 64.8% (P = 0.008). From the present study, we can conclude that besides tumors size and mitotic index, tumor location and necrosis also influence on the long-term survival of patient with malignant GISTs after surgical resection.

摘要： The biological behavior of gastrointestinal stromal tumors (GISTs) are highly variable. To investigate the biological behavior of GIST, we collected 83 cases of gastric and 62 cases of small intestinal GIST from the Department of Pathology of the Chinese PLA General Hospital. The parameters include age, primary tumor location, tumor diameter, mitotic index, tumor necrosis, risk assessment, clinical stage and the exon 11 mutation. All these were analyzed in 105 cases along with the follow-up data and tested by log rank and COX hazard proportional model. We find that the average age of gastric GIST was 55.4 years. Of the 62 cases that were followed up, 17 cases had metastasis or recurrence and the 5-year survival rate was (66.51 ± 17.06)%. For the small intestinal GIST, the average age was 50.6 years and 43 cases were followed up. Of these, 22 cases had metastasis or recurrence and the 5-year survival rate was (61.76 ± 18.30)%. Small intestinal GIST was more frequently associated with metastasis and tumor relapse than gastric GIST ( = 6.131, = 0.013). For gastric GIST, patients younger than 50 years ( = 0.046), the advanced clinical stage ( = 0.0001), the large tumor diameter ( = 0.0001), a high mitotic index ( = 0.0001), necrosis ( = 0.0001) and a high risk grade ( = 0.004) were all correlated with a lower survival rate. The COX hazard proportional model revealed that advanced clinical stage ( = 0.001), large tumor size ( = 0.001), a high mitotic index ( = 0.002) and the high risk grade ( = 0.018) indicated a poorer prognosis in gastric GIST. For small intestinal GIST, necrosis ( = 0.036) and advanced clinical stage ( = 0.010) were associated with lower survival rates and the clinical stage was shown to be an independent prognostic indicator. A total of 25 cases harbored mutations in exon 11. The frequency of mutation was 32% and 22.5% for gastric and small intestinal GIST, respectively. In gastric GIST, the mutated was predominant in patients older than 50 years of age. But in the small intestinal GIST, the mutated was predominant in the age group of 40–49 years. In conclusion, for gastric GIST, clinical stage, tumor size, mitotic index, and risk grade are the prognostic indicators. For small intestinal GIST, necrosis and clinical stage are the prognostic indicators. Small intestinal GIST are more aggressive than gastric GIST. The occurrence of mutation may correlate with the age of patients.

《医学前沿（英文）》 2009年 第3卷 第2期   页码 220-226 doi: 10.1007/s11684-009-0037-2

摘要： This study aimed to evaluate the effect of repeated ovarian stimulation (OS) on the ovarian follicular population and morphology in female mice and its influence on the embryo’s developmental ability, and the profile of the ovarian surface epithelium (OSE). A total of 75 mice were enrolled in this experiment and randomly assigned into three groups: repeated ovarian stimulated group [ =25; receiving 5 IU pregnant mare serum gonadotrophin (PMSG) and human chorionic gonadotropin (hCG) at 6 day intervals for 5 cycles]; single ovarian stimulated group ( =25; receiving 5 IU PMSG and hCG for 1 cycle), and control group ( =25; without additional treatment). The follicle number at various stages and the morphologies were recorded respectively in the three groups. The harvested oocytes or embryos, cleavage rate, good quality embryo rate, and blastocyst production rate were counted and calculated, and the proliferations of ovarian surface epithelium were evaluated respectively. In the three groups, the single ovarian stimulation treatment significantly increased the mean number of ovarian oocytes or embryos (39.25±10.77 one-cell embryos/female); on the other hand, repeated gonadotropin stimulation obtained the lowest mean number (5.15± 2.81 eggs/female, <0.01). Repeated ovarian stimulation also tended to decrease normal follicles of primary follicles (66.67%) and secondary follicles (72.86%), and got the lowest cleavage rate (67.47%), lowest good quality embryo rate (2.41%), and lowest blastocyst production rate (0). The OSE cells adjacent to the antral follicles and corpus luteum (CL) in the repeated ovarian stimulated group (81.8%) had a significantly higher proliferation rate than the other groups. The proliferation rate of the OSE in the single ovarian stimulated group (56.4%) was significantly higher than that in the control group (37.5%) ( <0.01). In conclusion, single ovarian stimulation may produce more oocytes/embryos. However, repeated gonadotropin stimulation may have a negative effect on the ovarian follicular quality, the number of mature retrieved oocytes, and the embryo quality, even increasing the chance of ovarian cancer.

摘要： The (half-smooth tongue sole) is a marine flatfish of great commercial value for fisheries and aquaculture in China. It has a female heterogametic sex determination system (ZW/ZZ) and environmental factors can induce sex-reversal of females to phenotypic males, suggesting that it is a promising model for the study of sex determination mechanisms. Additionally, females grow much faster than males and it is feasible to improve the aquaculture production through sex control techniques. This paper reviews the progress in research on sex determination mechanisms research in our laboratory. We have completed whole-genome sequencing and revealed the genome organization and sex chromosome evolution of . A putative male determining gene was identified and DNA methylation was verified as having a crucial role in the sex reversal process. Genetic maps and sex-specific biomarkers have been used in a marker-assisted selection breeding program and for differentiation of the fish sex. Development and improvement of sex control technologies, including artificial gynogenesis and production of breeding fry with high proportion of females, is also reviewed. These research advances have provided insight into the regulation of sex determination and enabled efficient sex management in artificial culturing of .

摘要：

This study used different methods to establish an animal model of orthotopic transplantation for ovarian cancer to provide an accurate simulation of the mechanism by which tumor occurs and develops in the human body. We implanted 4T1 breast cancer cells stably-transfected with luciferase into BALB/c mice by using three types of orthotopic transplantation methodologies: (1) cultured cells were directly injected into the mouse ovary; (2) cell suspension was initially implanted under the skin of the mouse neck; after tumor mass formed, the tumor was removed and ground into cell suspension, which was then injected into the mouse ovary; and (3) a subcutaneous tumor mass was first generated, removed, and cut into small pieces, which were directly implanted into the mouse ovary. After these models were established, in vivo luminescence imaging was performed. Results and data were compared among groups. Orthotopic transplantation model established with subcutaneous tumor piece implantation showed a better simulation of tumor development and invasion in mice. This model also displayed negligible response to artificial factors. This study successfully established an orthotopic transplantation model of ovarian cancer with high rates of tumor formation and metastasis by using subcutaneous tumor pieces. This study also provided a methodological basis for future establishment of an animal model of ovarian cancer in humans.

Rare tumors: a blue ocean of investigation

《医学前沿（英文）》 2023年 第17卷 第2期   页码 220-230 doi: 10.1007/s11684-023-0984-z

摘要： Advances in novel drugs, therapies, and genetic techniques have revolutionized the diagnosis and treatment of cancers, substantially improving cancer patients’ prognosis. Although rare tumors account for a non-negligible number, the practice of precision medicine and development of novel therapies are largely hampered by many obstacles. Their low incidence and drastic regional disparities result in the difficulty of informative evidence-based diagnosis and subtyping. Sample exhaustion due to difficulty in diagnosis also leads to a lack of recommended therapeutic strategies in clinical guidelines, insufficient biomarkers for prognosis/efficacy, and inability to identify potential novel therapies in clinical trials. Herein, by reviewing the epidemiological data of Chinese solid tumors and publications defining rare tumors in other areas, we proposed a definition of rare tumor in China, including 515 tumor types with incidences of less than 2.5/100 000 per year. We also summarized the current diagnosis process, treatment recommendations, and global developmental progress of targeted drugs and immunotherapy agents on the status quo. Lastly, we pinpointed the current recommendation chance for patients with rare tumors to be involved in a clinical trial by NCCN. With this informative report, we aimed to raise awareness on the importance of rare tumor investigations and guarantee a bright future for rare tumor patients.

摘要：

Hemoperitoneum is a rare and potentially life-threatening complication of GIST. We reported a 54-year-old man who developed disseminated intra-abdominal recurrence from a previously resected gastrointestinal stromal tumour (GIST) of the small bowel, and the patient presented with hemoperitoneum. Emergent debulking surgery was performed. A high dose imatinib was prescribed. Despite the presence of residual disease, the patient was well clinically 8 months after the operation. Even though, there is no evidence to support the routine use of debulking surgery in the management of GIST. In our patient, disease progression after second line targeted therapy and the absence of alternative treatment options for spontaneous rupture and hemoperitoneum prompted us to treat the patient aggressively. Resection of the ruptured GIST was carried out for control of bleeding and to prevent recurrent bleeding in this patient with good surgical risks. During the treatment decision-making, the patient’s general condition, the risk of surgery and the extent of dissemination were taken into consideration. In this patient who presented with spontaneous rupture of a small intestinal GIST, the novel use of targeted therapy and aggressive surgical treatment produced reasonably good survival outcome.

《医学前沿（英文）》 2015年 第9卷 第1期   页码 20-29 doi: 10.1007/s11684-014-0371-x

摘要：

Ischemic stroke is a focal cerebral insult that often leads to many adverse neurological complications severely affecting the quality of life. The prevalence of stroke is increasing throughout the world, while the efficacy of current pharmacological therapies remains unclear. As a neuroregenerative therapy, the implantation of human umbilical cord mesenchymal stem cells (hUC-MSCs) has shown great possibility to restore function after stroke. This review article provides an update role of hUC-MSCs implantation in the treatment of ischemic stroke. With the unique “immunosuppressive and immunoprivilege” property, hUC-MSCs are advised to be an important candidate for allogeneic cell treatment. Nevertheless, most of the treatments are still at primary stage and not clinically feasible at the current time. Several uncertain problems, such as culture conditions, allograft rejection, and potential tumorigenicity, are the choke points in this cellular therapy. More preclinical researches and clinical studies are needed before hUC-MSCs implantation can be used as a routinely applied clinical therapy.

《医学前沿（英文）》 2009年 第3卷 第1期   页码 45-48 doi: 10.1007/s11684-009-0019-4

摘要： This study was aimed to explore the anterior cervical surgery methods to treat central cord syndrome without radiographic spinal fracture-dislocation (CCSWORFD), retrospectively analyze the cases of CCSWORFD, and evaluate the curative effect of anterior cervical surgery methods for CCSWORFD. Twenty four cases of CCSWORFD (19 males and 5 females), all suffering from cervical hyperextension injury, between 45-68 (average 59) years old, were operated on by anterior cervical surgery methods. Among these, 18 cases had been followed up for 6-24 (average 15) months; 18 cases, who had anterior decompression and plate fixation with titanium mesh bone grafting or iliac bone grafting achieved reliable effects based on the Japanese Orthopedics Association (JOA) evaluation (improved scores of cases with titanium mesh bone grafting, = 2.800, <0.05; improved scores of cases with iliac bone grafting, = 3.270, <0.05), and reliable reconstruction of cervical spine. The two groups obtained the same curative effect ( = 0.470, >0.05) Most of these cases had degeneration of cervical vertebra. The decompression which relieves the oppression to the spinal cord can help lessen edema of the spinal cord, and early fixation for stability of cervical vertebra is better for the recovery of spinal cord injury. Anterior operation with titanium mesh bone grafting or iliac bone grafting are both reliable curative methods for CCSWORFD, and titanium mesh bone grafting can avoid the trauma of the supplying graft. Mesh bone grafting can also shorten hospital stay.

Immunological effects of nano-enabled hyperthermia for solid tumors: opportunity and challenge

《化学科学与工程前沿（英文）》 2022年 第16卷 第3期   页码 333-344 doi: 10.1007/s11705-021-2059-5

摘要： Compared to conventional hyperthermia that is limited by low selectivity and severe side effects, nano-enabled hyperthermia yields great potentials to tackle these limitations for cancer treatment. Another major advance is the observation of immunological responses associated with nano-enabled hyperthermia, which introduces a new avenue, allowing a potential paradigm shift from the acutely effective and cytotoxicity-centric response to the next-phase discovery, i.e., long-lasting and/or systemic anti-tumor immunity. This perspective first discusses the temperature-gradient and the spatially-structured immunological landscape in solid tumors receiving nano-enabled hyperthermia. This includes the discussion about underlying mechanism such as immunogenic cell death, which initiates a profound immunological chain reaction. In order to propagate the immune activation as a viable therapeutic principle, we further discussed the tumor type-specific complexity in the immunological tumor microenvironment, including the creative design of nano-enabled combination therapy to synergize with nano-enabled hyperthermia.

Efficacy of intelligent diagnosis with a dynamic uncertain causality graph model for rare disorders of sex

Dongping Ning, Zhan Zhang, Kun Qiu, Lin Lu, Qin Zhang, Yan Zhu, Renzhi Wang

《医学前沿（英文）》 2020年 第14卷 第4期   页码 498-505 doi: 10.1007/s11684-020-0791-8

摘要： Disorders of sex development (DSD) are a group of rare complex clinical syndromes with multiple etiologies. Distinguishing the various causes of DSD is quite difficult in clinical practice, even for senior general physicians because of the similar and atypical clinical manifestations of these conditions. In addition, DSD are difficult to diagnose because most primary doctors receive insufficient training for DSD. Delayed diagnoses and misdiagnoses are common for patients with DSD and lead to poor treatment and prognoses. On the basis of the principles and algorithms of dynamic uncertain causality graph (DUCG), a diagnosis model for DSD was jointly constructed by experts on DSD and engineers of artificial intelligence. “Chaining” inference algorithm and weighted logic operation mechanism were applied to guarantee the accuracy and efficiency of diagnostic reasoning under incomplete situations and uncertain information. Verification was performed using 153 selected clinical cases involving nine common DSD-related diseases and three causes other than DSD as the differential diagnosis. The model had an accuracy of 94.1%, which was significantly higher than that of interns and third-year residents. In conclusion, the DUCG model has broad application prospects as a computer-aided diagnostic tool for DSD-related diseases.

Umbilical cord-derived mesenchymal stem cells: strategies, challenges, and potential for cutaneous regeneration

摘要：

Umbilical cord mesenchymal stem cells (MSCs) are a unique, accessible, and non-controversial source of early stem cells that can be readily manipulated. As the most common pluripotent cell, bone marrow-derived MSCs display limitations with the progress of stem cell therapy. By contrast, umbilical cord-derived cells, which have plentiful resources, are more accessible. However, several uncertain aspects, such as the effect of donor selection or culture conditions, long-term therapeutic effects, product consistency, and potential tumorigenicity, are the bottleneck in this clinical therapy. MSCs are predicted to undergo an unprecedented development in clinical treatment when a generally acknowledged criterion emerges. In the current paper, we highlight the application of umbilical cord-derived MSCs in skin therapies based on our previous studies, as well as the achievements of our peers in this field. This paper focuses on the strategies, challenges, and potential of this novel therapy.

《医学前沿（英文）》 2014年 第8卷 第1期   页码 91-95 doi: 10.1007/s11684-014-0305-7

摘要：

A total of 251 patients with epithelial ovarian cancer (EOC) treated between 2002 and 2008 was retrospectively analyzed to investigate the long-term outcomes and prognostic factors of these patients, particularly those who underwent primary debulking surgery followed by platinum-based chemotherapy. Clinico-pathological parameters, including progression-free survival (PFS) and overall survival (OS), were also analyzed. The median follow-up period from the end of initial treatment to June 2010 was 58 months. The three-year PFS rate was 61.7% for International Federation of Gynecology and Obstetrics (FIGO) I–II, 19.9% for FIGO III–IV, and 33.9% for all stages. By comparison, the five-year PFS rate was 44.6% for FIGO I–II, 17.7% for FIGO III–IV, and 28.3% for all stages. The three-year OS rate was 67.9% for FIGO I–II, 41.7% for FIGO III–IV, and 50.2% for all stages. The five-year OS rate was 52.7% for FIGO I–II, 30.8% for FIGO III–IV, and 39.2% for all stages. Univariate analysis revealed that advanced FIGO stage, serum CA125, and suboptimal debulking were significant factors affecting PFS and OS. In multivariate analysis, PFS was significantly influenced by FIGO stage and suboptimal debulking. However, OS was significantly influenced by advanced FIGO stage only. Our study confirms the efficacy of surgery followed by platinum-based chemotherapy for EOC. FIGO stage is considered as one of the most reliable predictors of the prognosis of patients with EOC.

摘要：

Lymph node metastasis has an important effect on prognosis of patients with ovarian cancer. Moreover, the impact of para-aortic lymph node (PAN) removal on patient prognosis is still unclear. In this study, 80 patients were divided into groups A and B. Group A consisted of 30 patients who underwent PAN+ pelvic lymph node (PLN) dissection, whereas group B consisted of 50 patients who only underwent PLN dissection. Analysis of the correlation between PAN clearance and prognosis in epithelial ovarian cancer was conducted. Nineteen cases of lymph node metastasis were found in group A, among whom seven cases were positive for PAN, three cases for PLN, and nine cases for both PAN and PLN. In group B, 13 cases were positive for lymph node metastasis. Our study suggested that the metastatic rate of lymph node is 40.0%. Lymph node metastasis was significantly correlated with FIGO stage, tumor differentiation, and histological type both in groups A and B (P<0.05). In groups A and B, the three-year survival rates were 77.9% and 69.0%, and the five-year survival rates were 46.7% and 39.2%, respectively. However, the difference was not statistically significant (P>0.05). The three-year survival rates of PLN metastasis in groups A and B were 68.5% and 41.4%, and the five-year survival rates were 49.7% and 26.4%, respectively. Furthermore, PLN-positive patients who cleared PAN had significantly higher survival rate (P=0.044). In group A, the three-year survival rates of positive and negative lymph nodes were 43.5% and 72.7%, and the five-year survival rates were 27.2% and 58.5%, respectively. The difference was statistically significant (P=0.048). Cox model analysis of single factor suggested that lymph node status affected the survival rate (P<0.01), which was the death risk factor. Consequently, in ovarian carcinoma cytoreductive surgery, resection of the para-aortic lymph node, which has an important function in clinical treatment and prognosis of patients with ovarian cancer, is necessary.
