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

Li Jiang, Deng Ning, Xiaoping Chen

Frontiers of Medicine 2020, Volume 14, Issue 3,   Pages 251-261 doi: 10.1007/s11684-019-0727-3

Abstract: 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.

An exploratory study for predicting component reliability with new load conditions

Zhengwei HU, Xiaoping DU

Frontiers of Mechanical Engineering 2019, Volume 14, Issue 1,   Pages 76-84 doi: 10.1007/s11465-018-0522-x

Abstract: Reliability is important to design innovation. A new product should be not only innovative, but also reliable. For many existing components used in the new product, their reliability will change because the applied Loads are different from the ones for which the components are originally designed and manufactured. Then the new reliability must be re-evaluated. The system designers of the new product, however, may not have enough information to perform this task. With a beam problem as a case study, this study explores a feasible way to re-evaluate the component reliability with new Loads given the following information: The original reliability of the component with respect to the component Loads and the distributions of the new component Loads. Physics-based methods are employed to build the equivalent component limit-state function that can predict the component failure under the new Loads. Since the information is limited, the re-evaluated component reliability is given by its maximum and minimum values. The case study shows that good accuracy can be obtained even though the new reliability is provided with the aforementioned interval.

Clustering economic sectors in China on a life cycle basis to achieve environmental sustainability

Sai LIANG, Tianzhu ZHANG, Xiaoping JIA

Frontiers of Environmental Science & Engineering 2013, Volume 7, Issue 1,   Pages 97-108 doi: 10.1007/s11783-012-0402-2

Abstract: To improve material efficiency, industrial structure optimization becomes a focal point in Chinese industrial and environmental policies. It is crucial to cluster economic sectors and determine their priority for industrial and environmental policy implementation. Integrating a set of criteria, a hybrid input-output model and the hierarchical cluster analysis, this study clusters China’s economic sectors and determines their priority on a life cycle basis. China’s economic sectors are clustered into three clusters. Industrial structure changes (industrial policy) should encourage the development of sectors in cluster 1 and limit the development of sectors in cluster 2. Technology development and materials recycling (two environmental policies) should mainly focus on sectors in clusters 1 and 2. Future industrial policies in China should limit the development of two sectors named and . Instead of limiting some industries by command-and-control, the best policy option is to remedy environmental standards and law enforcement. Enterprises belonging to the identified key sectors from the viewpoint of direct production impacts should be concerned to achieve enterprise sustainability. To achieve sustainable production chains, the identified key sectors from the viewpoint of accumulative production impacts should be concerned. For sustainable consumption, the identified key sectors from the viewpoint of consumption impacts should be concerned to transform consumption styles. Most of environmental pressure can be alleviated not only by technical improvements and material recycling, but also by the development of economic sectors in cluster 1.

An 84-month observational study of the changes in CD4 T-lymphocyte cell count of 110 HIV/AIDS patients treated with traditional Chinese medicine

Jian Wang,Biyan Liang,Xiaoping Zhang,Liran Xu,Xin Deng,Xiuhui Li,Lu Fang,Xinghua Tan,Yuxiang Mao,Guoliang

Frontiers of Medicine 2014, Volume 8, Issue 3,   Pages 362-367 doi: 10.1007/s11684-014-0363-x

Abstract:

This study aimed to evaluate the therapeutic effect of traditional Chinese medicine (TCM) by observing the changes in CD4 T-lymphocyte cell count of 110 cases with human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) treated continuously with TCM for 84 months. Information of 110 HIV/AIDS patients from 19 provinces and cities treated with TCM from 2004 to 2013 was collected. Changes in the indexes of CD4 counts (≤200, 201–350, 351–500 and>500 cells/mm3) at five time points (0, 12, 36, 60 and 84 months) and different treatments [TCM and TCM plus antiretroviral therapy (ART)] were compared. Repeated measures test indicated no interaction between group and time (P>0.05). Degrees of increasing and decreasing CD4 count of the two groups at four different frames were statistically significant compared with the baseline. The CD4 count between the two groups was not statistically significant. For CD4 count of≤200 cells/mm3, the mean CD4 count changes were 21 and 28 cells/mm3 per year for the TCM group and TCM plus ART group, respectively. For CD4 count of 201–350 cells/mm3, the mean CD4 count changes were 6 and 25 cells/mm3 per year for the TCM group and TCM plus ART group, respectively. For CD4 count of 351–500 cells/mm3, the mean CD4 count changes were -13 and -7 cells/mm3 per year for the TCM group and TCM plus ART group, respectively. For CD4 count of>500 cells/mm3, the mean CD4 count changes were -34 and -17 cells/mm3 per year for the TCM group and TCM plus ART group, respectively. Long-term use of TCM could maintain or slow the pace of declining CD4 counts in patients with HIV/AIDS, and may achieve lasting effectiveness.

Driving mechanism and boundary control of urban sprawl

Dongmei JIANG,Xiaoshun LI,Futian QU,Mingyan LI,Shaoliang ZHANG,Yunlong GONG,Xiaoping SHI,Xin CHEN

Frontiers of Environmental Science & Engineering 2015, Volume 9, Issue 2,   Pages 298-309 doi: 10.1007/s11783-014-0639-z

Abstract: Since the reform and opening-up, China’s economy has achieved remarkable development and so does the urbanization. However, there is an unavoidable contradiction between urban sprawl and the protection of arable land and the environment. By redefining the urban sprawl boundary, this paper is to provide a solution for the conflict above on the China’s urbanization context. The ideal boundary, moderate boundary and limit boundary are defined for urban sprawl in space. Taking Nanjing city as a case, the three urban sprawl boundaries are estimated in this paper based on the calculation of agricultural land resources value in Nanjing. The results show that 1) the integrated value of agricultural (cultivated) land resources in Nanjing is 1.55 × 10 CNY·hm , the economic value accounts for only 8.74% of the integrated value, while 91.26% of the integrated value has not revealed itself due to the existing institutional arrangements, policy distortions, and imperfect land market; 2) it is difficult to define the ideal and moderate boundaries due to the relatively low price of North Nanjing. In South Nanjing the land price is expensive and the ideal, moderate and limit boundaries are expanded to Jiangning, Qixia, and Yuhuatai; 3) the city scale of South Nanjing should be limited within 5.82 × 10 hm , which is roughly the same as the designated size of 5.81 × 10 hm in the urban planning. It is suggested that the rational scope of urban expansion should be controlled within the moderate boundary.

Surgical treatment of hepatocellular carcinoma with cirrhotic esophageal varices and hypersplenism: a 184 case report

JIANG Bin, CHEN Xiaoping, HUANG Zhiyong, ZHANG Zhiwei, HE Songqing, WANG Shaofa, WU Zaide, QIU Fazu

Frontiers of Medicine 2007, Volume 1, Issue 1,   Pages 24-29 doi: 10.1007/s11684-007-0005-7

Abstract: In treating hepatocellular carcinoma (HCC) patients with advanced cirrhosis, one of the most difficult problems is concomitant esophageal varices and hypersplenism. Whether these conditions should be treated surgically in association with HCC resection is still in debate. To elucidate whether esophageal devascularization or splenectomy is beneficial when simultaneously performed with liver resection in HCC patients with both varices and hypersplenism, HCC patients ( = 184) with esophageal varices and hypersplenism received one of the three treatments: simultaneous liver resection and esophageal devascularization (Group I, = 41); simultaneous liver resection and splenectomy (Group II, = 61); liver resection only (Group III, = 82). The incidences of postoperative complications of the three groups were 31.7%, 29.5% and 24.4%, respectively, with no significant difference among them. The 5-year tumor-free survival rates for the group I, group II and group III were 34.1%, 36.1% and 37.8%, respectively. Variceal bleeding caused death by only 4.2% in group I, but by 14.3% in group II and 23.2% in group III. The survival rates in the group I and the group II were comparable to those in the group III, however, the recurrences of postoperative fatal variceal bleeding in group I and group II were significantly lower than those in group III. The results suggest that HCC patients with esophageal varices and hypersplenism should undergo hepatic resection plus esophageal devascularization or splenectomy if radical resection of HCC can be expected.

A way to explain the thermal boundary effects on laminar convection through a square duct

Liangbi WANG, Xiaoping GAI, Kun HUANG, Yongheng ZHANG, Xiang YANG, Xiang WU

Frontiers in Energy 2010, Volume 4, Issue 4,   Pages 496-506 doi: 10.1007/s11708-010-0020-2

Abstract: A way using the reformulation of the energy conservation equation in terms of heat flux to explain the thermal boundary effects on laminar convective heat transfer through a square duct is presented. For a laminar convection through a square duct, it explains that on the wall surface, the velocity is zero, but convection occurs for uniform wall heat flux (UWHF) boundary in the developing region due to the velocity gradient term; for uniform wall temperature (UWT) boundary, only diffusion process occurs on the wall surface because both velocity and velocity gradient do not contribute to convection; for UWHF, the largest term of the gradient of velocity components (the main flow velocity) on the wall surface takes a role in the convection of the heat flux normal to the wall surface, and this role exists in the fully developed region. Therefore, a stronger convection process occurs for UWHF than for UWT on the wall surface. The thermal boundary effects on the laminar convection inside the flow are also detailed.

Frontiers of Agricultural Science and Engineering 2015, Volume 2, Issue 4,   Pages 335-340 doi: 10.15302/J-FASE-2015079

Abstract: Twelve (+)-nopinone-based 2-amino-3-cyanopyridines 4a–l were synthesized from (–)-β-pinene. The structures of these compounds were characterized by FT-IR, H NMR, and ESI-MS. All the compounds were tested for their anticancer activity against lung cancer cell line A549, gastric cancer cell line MKN45 and breast cancer cell line MCF7 by MTT method, respectively. The results showed that compounds 4f, 4j and 4k had promising anticancer activity against these cancer cell lines, in particular, compound 4f exhibited broad-spectrum and highly efficient anticancer activity against cell lines A549, MKN45 and MCF7 with IC of 23.78, 67.61 and 53.87 µmol·L , respectively. The preliminary analysis of the structure activity relationship implied that the Br or Cl substituted group of the benzene ring in these derivatives significantly contributed to the anticancer activity.

Absence of FHIT expression is associated with apoptosis inhibition in colorectal cancer

CAO Jie, LI Wanglin, XIA Jie, TANG Weibiao, WANG Hui, CHEN Xiwen, XIAO Huanqing, LI Yuyuan, CHEN Xiaoping

Frontiers of Medicine 2007, Volume 1, Issue 2,   Pages 147-156 doi: 10.1007/s11684-007-0028-0

Abstract: The fragile histidine triad (FHIT) gene, a candidate tumor suppressor gene located at 3p14.2, has been shown to be involved in the carcinogenesis of many human tissues, including digestive tract tissues. However, the expression and the role of the FHIT in the initiation and the development of the colorectal cancer (CRC) are poorly understood. We have shown that the FHIT gene exhibits significantly decreased expression in human CRC compared to colorectal adenoma and normal colorectal tissue by tissue microarray (TMA). The positive rate of FHIT gene expression in normal colorectal tissue, adenoma and adenocarcinoma were 93.75%, 68.75% and 46.25%, respectively. We show this decreased expression to be significantly correlated with the progression of colorectal carcinoma (<0.05) as well as with differentiation and lymph node metastasis (<0.05). We detected two somatic alterations in the FHIT gene in human CRC. The presence of this mutation correlated significantly with decreased FHIT expression in the human CRC. In our present study we tested the hypothesis that the decreased FHIT expression resulted in apoptosis inhibition associated with abnormal expression of apoptosis related proteins. To test this hypothesis we did a series of experiments. In the first test, we assessed apoptosis status using a standard TUNEL (terminal deoxynucleotidyl transferase-mediated dUTP nick-end-labeling) assay by comparing FHIT-positive CRC vs. FHIT-negative CRC. In the second experiment, the protein expression of the FHIT and other apoptosis related proteins (Bax, Bcl-2 and Survivin) were measured in human CRC by TMA. Our combined results demonstrate the mutation in the FHIT gene significantly reduced FHIT expression in human CRC. Both TUNEL and TMA experiments demonstrated significantly inhibited apoptosis by down-regulation of Bax and the up-regulation of Survivin and Bcl-2. Collectively, these studies identify the mechanism by which an important tumor suppressor gene, FHIT is inactivated specifically in human CRC contributing to our understanding of the mechanism of colorectal carcinogenesis.
