摘要：

von Hippel-Lindau (VHL) disease is a rare, inherited neoplastic disease characterized by hemangioblastomas (HBL) of the central nervous system (CNS), retinal angiomas, renal cell carcinomas (RCC), pancreatic endocrine tumors (PETs), pheochromocytomas, paragangliomas, and visceral cysts. We encountered a large VHL family in northwest China and conducted a systematic screening of the family members based on their epidemiological and clinical characteristics. A self-designed questionnaire was used to collect the general sociodemographic and health information of the family members. For the preliminary family screening, physical examination and abdomen B ultrasonography were performed. The suspected patients were subjected to cranial computerized tomography and fundus examination. The clinical data of the patients with confirmed VHL disease were collected from hospital records. A total of 63 lineal descendants in six generations were observed in the family (generations O, A, B, C, D, E), including 9 dead suspected cases (6 males, 3 females) and 10 living cases (2 males, 8 females). Among the 10 living cases, 4, 2, 1, 3, 4, 8, and 2 manifested HBLs of the CNS, PETs, RCC, pancreatic cysts, renal cysts, pheochromocytomas (4 hemi and 4 bilateral), and paragangliomas, respectively. Data showed that the morbidity of VHL disease in generation C was lower than that in generation B, but the age of onset was younger. This study is the first to report VHL disease in northwest China and VHL-associated PET cases in Chinese. Therefore, follow-up checkups of the family should be focused on younger generations. Proper family screening protocols should be followed for the treatment of patients with VHL disease.

Laparoscopic surgery for pancreatic lesions: current status and future

Taiping Zhang, Xiao Du, Yupei Zhao

《医学前沿（英文）》 2011年 第5卷 第3期   页码 277-282 doi: 10.1007/s11684-011-0147-5

摘要： Laparoscopic pancreatic surgery has been gaining increasing recognition in recent years, and its practice has increased despite its highly complex procedure and longer learning curve compared with surgeries for other abdominal organs. Laparoscopic distal pancreatectomy and tumor enucleation are two of the fastest-growing techniques and are currently in wide use because of their comparable technical simplicity. Literature review showed that laparoscopic distal pancreatectomy and enucleation are safe and efficient approaches for benign and low-degree malignant tumors; however, the indication for malignant tumors remains controversial. Laparoscopic pancreaticoduodenectomy is practiced in a limited number of surgical centers and presented as case reports or in small series. Although its feasibility was demonstrated by many surgeons, whether the laparoscopic procedure can achieve benefits comparable to or even more prominent than those of an open procedure has not been clinically proven. Prospective, randomized, controlled trials of laparoscopic operation versus open pancreatic surgery are necessary to justify the wide application and routine practice of the laparoscopic procedure for pancreatic lesions.

Prevention and treatment of pancreatic fistula after pancreatic body and tail resection: current status

Li Jiang, Deng Ning, Xiaoping Chen

《医学前沿（英文）》 2020年 第14卷 第3期   页码 251-261 doi: 10.1007/s11684-019-0727-3

摘要： Postoperative pancreatic fistula (POPF) is the most common and critical complication after pancreatic body and tail resection. How to effectively reduce the occurrence of pancreatic fistula and conduct timely treatment thereafter is an urgent clinical issue to be solved. Recent research standardized the definition of pancreatic fistula and stressed the correlation between POPF classification and patient prognosis. According to the literature, identification of the risk factors for pancreatic fistula contributed to lowering the rate of the complication. Appropriate management of the pancreatic stump and perioperative treatment are of great significance to reduce the rate of POPF in clinical practice. After the occurrence of POPF, the treatment of choice should be determined according to the classification of the pancreatic fistula. However, despite the progress and promising treatment approaches, POPF remains to be a clinical issue that warrants further studies in the future.

The role of prophylactic transpapillary pancreatic stenting in distal pancreatectomy: a meta-analysis

null

《医学前沿（英文）》 2013年 第7卷 第4期   页码 499-505 doi: 10.1007/s11684-013-0296-9

摘要：

Pancreatic fistula (PF) is the most frequent complication after distal pancreatectomy (DP). Prophylactic transpapillary pancreatic stenting (PTPS) has been proposed recently for the prevention of PF after DP. In this meta-analysis, a comprehensive search was performed in the PubMed, Embase, and Cochrane Library databases. Studies analyzing the results of PTPS in DP were considered eligible for this meta-analysis. The analyzed outcome variables included PF rate, postoperative morbidity, non-PF-related complications, mortality, operation duration, and hospital stay. Four studies with 200 patients were included in this review. Only one was a randomized controlled trial (RCT). The results showed that PTPS was associated with less PF formation (odds ratio, 0.45; 95% confidence interval [CI], 0.22–0.94; P = 0.03) and shorter hospital stay (mean difference, -6.31; 95% CI, -6.99 to -5.62; P<0.00001). There was no significant difference in terms of the other variables. In conclusion, current evidence indicates that PTPS could reduce PF incidence and hospital stay after DP, without increasing other complications or operative time. However, the evidence is not solid, because the single RCT conflicted with the other three retrospective reports. Thus, considering the limitation, more well-designed RCTs on this topic are needed in the future.

Determination and occurrence of endocrine disrupting compounds, pharmaceuticals and personal care products

Yong YU,Laosheng WU

《环境科学与工程前沿（英文）》 2015年 第9卷 第3期   页码 475-481 doi: 10.1007/s11783-014-0640-6

摘要： Endocrine disrupting compounds (EDCs), pharmaceuticals and personal care products (PPCPs) have attracted much attention due to widespread contamination in aquatic environment. In this study, we determined 13 EDCs and PPCPs in fish blood, bile and muscle by using gas chromatography-mass spectrometry (GC-MS). The limits of quantitation (LOQ) were in the ranges of 0.23–2.54, 0.22–2.36 ng·mL , and 0.24–2.57 ng·g dry weight (dw) for fish blood, bile and muscle, respectively. Recoveries of target compounds spiked into sample matrices and passed through the entire analytical procedure ranged from 65% to 95%, from 60% to 92% and from 62% to 91% for blood, bile and muscle, respectively. The methods were applied to the analysis of fish from a lake in California. Target compounds were relatively low in bile, and only bisphenol A (BPA) and diclofenac were measurable near the LOQ. Seven of 13 compounds were detected in blood, with total concentrations up to 39 ng·mL . Only BPA was frequently found in muscle, with mean concentration of 7.26 ng·g dw. The estimated daily intake of BPA through fish consumption for U.S. resident was significantly lower than the tolerable daily intake recommended by the European Food Safety Authority. This study showed that the exposure to the bisphenol A from fish diet is unlikely to pose a health risk.

Overcoming resistance to endocrine therapy in hormone receptor-positive human epidermal growth factor

Wenjie Zhu, Binghe Xu

《医学前沿（英文）》 2021年 第15卷 第2期   页码 208-220 doi: 10.1007/s11684-020-0795-4

摘要： New targeted therapies have been developed to overcome resistance to endocrine therapy (ET) and improve the outcome of HR /HER2 advanced breast cancer (ABC). We conducted a meta-analysis and systemic review on randomized controlled trials evaluating various targeted therapies in combination with ET in HR /HER2 ABC. PUBMED and EMBASE databases were searched for eligible trials. Hazard ratios (HRs) for progression-free survival (PFS), odds ratios (ORs) for objective response rate (ORR), clinical benefit rate (CBR), and toxicity were meta-analyzed. Twenty-six studies with data on 10 347 patients were included and pooled. The addition of cyclin-dependent kinase 4/6 inhibitors to ET significantly improved median PFS (pooled HR= 0.547, <0.001), overall survival (pooled HR= 0.755, <0.001), and tumor response rates (ORR, pooled OR= 1.478, <0.001; CBR, pooled OR= 1.201, <0.001) with manageable toxicities (pooled OR= 3.280, <0.001). The mammalian targets of rapamycin inhibitors and exemestane were not clinically beneficial for this pooled population including ET-naïve and ET-resistant patients. Moderate improvement in PFS (pooled HR= 0.686, <0.001) yet pronounced toxicities (pooled OR= 2.154, <0.001) were noted in the combination of phosphatidylinositol-4,5-bisphosphate 3-kinase inhibitors with fulvestrant. Future studies are warranted to optimize the population and the dosing sequence of these available options.

Influence of the adjuvant therapy on the survival of patients with stage II pancreatic carcinoma

Xi-Yan WANG, Hai-Jun LI, Dong YAN, Hao WEN, Shu-Yong PENG,

《医学前沿（英文）》 2010年 第4卷 第4期   页码 430-435 doi: 10.1007/s11684-010-0700-7

摘要： This study aimed to investigate the effect of adjuvant therapy on the treatment of stage II pancreatic carcinomas. The clinical data of 139 cases of stage II pancreatic carcinoma were analyzed retrospectively. The overall 1-, 3-, and 5-year cumulative survival rates of 139 patients were 40%, 6%, and 3%, respectively, and the median survival time (MST) was 279 days. The MST was 399 days for those with adjuvant therapy, 210 days for those without adjuvant therapy, 390 days for the radical resection group, 270 days for the bypass operation and laparotomy group, and 132 days for the nonsurgical group. The adjuvant therapy could not prolong the survival time and decrease the liver metastasis rate of the patients with stage II carcinoma significantly in radical resection group (>0.05). In the bypass operation and laparotomy group and nonsurgical group, the adjuvant therapy could improve the survival of the patients significantly (<0.05); however, the survival rate was not significantly different among systemic venous chemotherapy, radiation therapy, interventional therapy, and combination therapy (>0.05); or between gemcitabine (GEM) regimen and 5-fluorouracil regimen (>0.05); or between GEM monotherapy and GEM combined with platinum/capecitabine (>0.05). The proper adjuvant therapy can be suggested according to the general condition of the patients after radical resection for stage II pancreatic carcinoma. Chemotherapy combined with radiation should be applied actively for the patients whose cancerous tissues were not radically resected. The clinical efficacy of GEM combined with platinum/capecitabine is relatively better than GEM.

《环境科学与工程前沿（英文）》 2014年 第8卷 第1期   页码 18-26 doi: 10.1007/s11783-013-0573-5

摘要： The purpose of this study was to give a worldwide overview of the concentrations of typical estrogenic endocrine disrupting chemicals (EDCs) in the effluent of sewage plants and then compare the concentration distribution of the estrogenic EDCs in ten countries based on the survey data of the estrogenic EDCs research. The concentrations of three main categories (totally eight kinds) of estrogenic EDCs including steroidal estrogens (estrone (E1), estradiol (E2), estriol (E3) and 17α-ethynylestradiol (EE2)), phenolic compounds (nonylphenol (NP) and bisphenol A (BPA)) and phthalate esters (dibutyl phthalate (DBP) and dibutyl phthalate (2-ethylhexyl) phthalate (DEHP)) in the effluents of sewage plants reported in major international journals over the past decade were collected. The statistics showed that the concentration distributions of eight kinds of EDCs were in the range of ng·L to μg·L . The concentrations of steroidal estrogens mainly ranged within 50.00 ng·L , and the median concentrations of E1, E2, E3 and EE2 were 11.00, 3.68, 4.90 and 1.00 ng·L , respectively. Phenolic compounds and phthalate esters were found at μg·L level (some individual values were at the high level of 40.00 μg·L ). The median concentrations of BPA, NP, DBP and DEHP were 0.06, 0.55, 0.07 and 0.88 μg·L , respectively. The concentrations of phenolic compounds and phthalate esters in the effluents were higher than that of steroids estrogens. The analysis of the concentration in various ten countries showed that steroids estrogens, phenolic compounds and phthalate esters in sewage plant effluents were detected with high concentration in Canada, Spain and China, respectively.

Analysis of 100 consecutive cases of resectable pancreatic neuroendocrine neoplasms: clinicopathological

null

《医学前沿（英文）》 2016年 第10卷 第4期   页码 444-450 doi: 10.1007/s11684-016-0471-x

摘要：

The incidence rate of pancreatic neuroendocrine neoplasms (pNENs) has increased rapidly in recent years. However, the clinicopathological characteristics of pNENs are poorly understood. Medical records of patients who underwent surgery and were confirmed as pNENs by pathological examination from January 2003 to February 2015 in Qilu Hospital were reviewed retrospectively. A total of 100 patients, 36 males and 64 females, were included with a mean operation age of 46.26±13.41 years. Among the 100 cases, 76 had insulinomas and 24 had non-functional pNENs. Tumor size ranged from 0.5 cm to 9 cm, and the mean size was 2.20±1.40 cm. The percentages of TNM stages I, II, III, and IV tumors were 89.0%, 8.0%, 0.0%, and 3.0%, respectively. Based on the WHO classification, pNENs were classified into three grades: G1, G2, and G3. G1, G2, and G3 tumors were confirmed in 72.9%, 23.7%, and 3.4% patients, respectively. The positive rates of CgA and Syn immunohistochemical staining were 94.5% (69/73) and 100% (74/74), respectively. Compared with insulinoma, non-functional pNENs have larger tumor sizes, more advanced TNM staging, a higher Ki-67 index, and a higher rate of liver metastasis (P<0.05). In conclusion, pNENs are heterogeneous tumors with varying clinical manifestations, diverse tumor biological characteristics, and different prognoses. Non-functional pNENs present a more aggressive behavioral model and have poorer prognosis than functional pNENs.

In vitro agonistic and antagonistic endocrine disrupting effects of organic extracts from waste water

Kaifeng RAO, Na LI, Mei MA, Zijian WANG

《环境科学与工程前沿（英文）》 2014年 第8卷 第1期   页码 69-78 doi: 10.1007/s11783-013-0502-7

摘要： Effluents from wastewater treatment plant (WWTP) have been reported to have a broad spectrum of endocrine disrupting compounds (EDCs). The majority of studies have focused on the occurrence of estrogenic activity, while ignoring nuclear hormone receptors (NRs) pathways. In the present study, a battery of in vitro yeast bioassays and a cell bioassay, including antagonistic and agonistic effects on estrogen receptor (ER), androgen receptor (AR), progesterone receptor (PR), estrogen-related receptor (ERR) and aryl hydrocarbon receptor (AHR), were conducted to evaluate the removal efficiencies of EDCs by different treatment processes of a WWTP located in Beijing. Estrogenic, anti-estrogenic, anti- androgenic, anti-progesteronic, anti-ERR and the activation of AHR activities were detected in samples from all treatment processes and the receiving water. The concentration of estrogenic contaminants with estradiol (E ) equivalent concentrations ranged from 0.82 × 10 to 3.54 × 10 g E -EQ·L . The concentration of anti-estrogenic contaminants with 4-hydroxytamoxifen (4-OHT) equivalent concentrations ranged from 1.24 × 10 to 2.36 × 10 g 4-OHT-EQ·L . The concentration of anti-androgenic contaminants ranged from 2.21 × 10 to 3.52 × 10 g flutamide-EQ·L . The concentration of anti-progesteronic contaminants ranged from 3.15 × 10 to 2.71 × 10 g RU486-EQ·L . The concentration of anti-ERR contaminants ranged from 7.09 × 10 to 6.50 × 10 g 4-OHT-EQ·L . The concentration of AHR activators ranged from 1.7 × 10 to 3.4 × 10 g TCDD-EQ·L . These processes including secondary clarifier, coagulation, as well as coal and sand filtration could eliminated 67.2% of estrogenic contaminants, 47.0% of anti-estrogenic contaminants, 98.3% of anti-androgenic contaminants, 88.4% of anti-progesteronic contaminants, 65.4% of anti-ERR contaminants and 46.9% of AHR activators. WWTP effluents contain multiple receptor disruptors may have very complex adverse effects on exposed organisms.
