Study the serum level of HGF, Cys C and TGF-beta1 in type 2 diabetic nephropathy (DN), the infect of Pingshen decoction on those index. Selected 69 cases of 2 type DN and randomly divided into therapy group (36 cases) and control group (33 cases). The therapy group were treated with Pingshen decoction 1 dose/d, bid po. The control group were treated with NephritisShu tablet, 6 tablet, tid po. 8 weeks was a course. Before and after treatment, we examine the serum level of HGF, Cys C and TGF-beta1 by ELISA and immunonephelometry, and compare with 30 cases of healthy control group. The study demonstrates that before treatment, the serum level of HGF in both groups were significantly lower than healthy control group (P < 0.01), but Cys C, TGF-beta1 were significantly higher (P < 0.01). After treatment, the serum level of HGF of both groups were increased. The serum level of HGF of therapy group were significantly higher than of control group (P < 0.01), but the serum level of Cys C and TGF-beta1 were significantly lower than control group (P < 0.01). The serum level of HGF was correlated negatively with Cys C,TGF-beta1. In control group, the UAER, urine beta2-MG and quantity of 24-hour urine protein were significantly decreased after treatment (P < 0.01). The index of urine of therapy group were significantly lower than control group (P < 0.01). Results indicate that test of serum level of HGF and Cys C,TGF-beta1 of diabetic nephropathy have important clinical significance. Pingshen decoction can effectively intervene in the serum level of HGF and Cys C, TGF-beta1 and index of urine.

OBJECTIVETo investigate the morphologic and functional characteristics of the immortalized human liver sinusoidal endothelial cell line (LSEC line).
METHODSImmunofluorescence staining and fluorescence microscopy were used to detect the classic endothelial cell markers in LSEC line, and flow cytometry was used to analyze the purity of the human LSEC line. The morphology (including W-P bodies and surface fenestrations) and phagocytotic capacity of the human LSEC line were observed by transmission and scanning electron microscope. The proliferation curve of the human LSEC line was analyzed by MTT assay. The functional differences between the human LSEC line and human primary LSEC in expression of ELAM-1 and ICAM-1, activities of fibrinolysis (PAI-1, t-PA, u-PA), releasing of IL-6 and IL-8 were compared respectively by enzyme linked immunosorbent assay. Comparison of the susceptibility to hypoxia-reoxygenation induced apoptosis between the human LSEC line and human primary LSEC were investigated by TUNEL.
RESULTSThe established human LSEC line maintained a high proliferative ability and has been passaged for more than 80 times in the absence of any growth factors. Immunofluorescence staining showed that the human LSEC line could express classic endothelial cell marks including von Willebrand Factor (vWF), and could take up acetylated low-density lipoproteins (Ac-LDL). The purity of the human LSEC line was confirmed over 95% by flow cytometric analysis. The W-P bodies and the phagocytosis of Dynabeads was demonstrated by transmission electron microscope. And fenestrations could be found cellular surface with scanning electron microscopy. When compared with human primary LSEC, the human LSEC line has an equivalent responsiveness to tumor necrosis factor in up-regulation of ELAM-1 and ICAM-1. The human LSEC line can also release PAI-1, t-PA, u-PA but can not release IL-6 and IL-8 to TNF-alpha. In contrast, human primary LSEC could release IL-6. The human LSEC line showed higher susceptibility to hypoxia-reoxygenation-induced apoptosis, and the percentage of apoptotic cells was as high as (38.4 +/- 6.7)%, while (28.6 +/- 4.5)% and (7.8 +/- 1.2)% respectively in primary LSEC and in human umbilical vein endothelial cells.
CONCLUSIONSThe established human LSEC line maintains the special phenotypes and the major functional characteristics, and especially maintains the high susceptibility to hypoxia-reoxygenation-induced apoptosis. Therefore it is feasible to use this cell line for the study of liver ischemia-reperfusion injury.

OBJECTIVETo detect the expression of dihydropyrimidine dehydrogenase (DPD) in pancreatic ductal adenocarcinoma (PDAC), and to investigate the relationships between DPD expression and the prognosis of PDAC.
METHODSImmunohistochemistry and tissue microarray techniques were used to exam the expression of DPD in the cancerous tissue in 156 patients admitted from January 2005 to December 2009, including 89 males and 67 females, with the age ranging from 35 to 81 years. The median age was 55 years.
RESULTSWith the positive rate of DPD 55.1%, the expression of DPD was correlated with the differentiation (P = 0.001), TNM staging of tumor (P = 0.021). No relationship was observed between the vessel invasion (P = 0.265), lymphatic metastasis (P = 0.123), neural invasion (P = 0.598) and DPD expression. In the follow-up 117 patients the overall median survival time was 14.2 months, in 58 cases expressed negative, the median survival time was 20.6 months; 39 cases expressed "+" and "++", the median survival time was 12.3 months; 20 cases expressed "+++", the median survival time was 6.8 months. The expression of DPD in pancreatic cancer was correlated with the prognosis of patients, those with higher expression pattern exhibited shorter survival time (P < 0.05). Univariate survival analysis revealed that DPD expression, TNM staging, lymphatic metastasis and neural invasion were factors related to prognosis (P < 0.05), while differentiation levels and vessel invasion were not. Multivariate survival analysis revealed that DPD expression (P = 0.002), lymphatic metastasis (P = 0.000) were two independent prognostic factors.
CONCLUSIONSThe expression levels of DPD was correlated to differentiation levels of pancreatic cancer and TNM staging; those with higher expression of DPD showed shorter survival time. DPD expression, lymphatic metastasis were independent prognostic factors for pancreatic cancer.

UNLABELLEDOBJECTIVE; To evaluate the clinical value of different CT diagnostic criteria for peripancreatic artery and vein invasion in pancreatic carcinoma through comparison with the findings on surgical exploration.
METHODSOf 72 patients of having suspected pancreatic carcinoma were examined by multiplane spiral CT. Among 43 confirmed by surgical pathology; 15 underwent pancreaticoduodenectomy; 28 were found to have unresectable tumors. The peri-pancreatic major vessels including the superior mesenteric artery, celiac artery, hepatic artery, superior mesenteric vein and portal vein were explored carefully during surgical exploration.
RESULTSThe criteria for peri-pancreatic artery invasion was the presence of one of the following signs: artery embeded in tumor, or more than half of the artery circumference involved by tumor with wall irregularity or stenosis. The sensitivity of the above described criteria was 75.0% (12/16). If the criteria of tumor involvement exceeding half of the vessel circumference were adhered to, the sensitivity was 87.5% (14/16), which was high than the former, but the specificity was lower than that of the former one (90.2% versus 95.1%). The criteria for peri-pancreatic vein invasion was presence of any of the following signs: vein obliteration, more than half of the vein circumference involved by tumor, vein wall irregularity, vein stenosis, tear-drop sign of superior mesenteric artery. The sensitivity of the above described criteria was 92.9% (39/42), higher than that of the criteria that more than half of the vessel circumference was involved by the tumor (69.0%, 29/42), but the specificity of both criteria was the same (97.4%, 37/38).
CONCLUSIONFor assessing peri-pancreatic artery and vein invasion, using the combination of different CT diagnostic criteria has higher accuracy than when using only criteria of more than half of vessel circumference involved by tumor.

To analyse the familial aggregation and genetic predisposition of Shen-yin deficiency syndrome (SYDS) in families with diabetes mellitus type 2 (DM2). Methods One hundred and forty-one DM2 patients were collected from 32 family lines in Nanjin area, in which the probands were differentiated as DM2 with SYDS. On them, genetic analysis on the characteristics of SYDS was conducted using pedigree analysis, morbidity and heritability of the first-degree relatives of the probands were calculated, and the action of familial SYDS factor on the genesis of the syndrome was assessed by multiple factors regression analysis. Results The morbidity rate of SYDS in the first-degree relatives of the probands was 33.71%, and the heritability, calculated by Falconer formula, was 80.6%. The fitting result of regression analysis showed that familial factor played an important role in SYDS genesis (OR = 5.61, P = 0.001), but DM2 itself is not an independent risk factor for it. Conclusion DM2 with SYDS shows the tendency of familial aggregation and genetic predisposition, genetic factor is associated with the genesis of the syndrome. Pedigree research is a good method for exploring the relationship between syndrome and genetic factor.

OBJECTIVETo investigate the prevention and treatment for postsurgical gastroparesis syndrome (PGS) after pancreaticoduodenectomy.
METHODSThe data of 18 PGS cases after pancreaticoduodenectomy were analyzed.
RESULTSPGS of these 18 patients occurred within 4-10 days after operation. All of the PGS patients were cured with mean 25.4 days by conservative therapy and no one received re-operation. PGS was closely associated with the operation procedure (chi(2)=3.90, P<0.05)and postoperative complications (chi(2)=3.92, P<0.05).
CONCLUSIONSIncidence of PGS can be decreased by improvement of surgical procedure and prevention of abdominal complications. PGS can be cured by conservative therapy generally. Re-operation should be avoided.

OBJECTIVETo evaluate the clinical outcome of 21 cases of total pancreatectomy.
METHODSThe clinical data of 21 cases of total pancreatectomy performed from April 2003 to June 2006 was retrospectively analyzed.
RESULTSAmong the 21 patients, 1 case combined with transverse colon resection, 1 case with total gastrectomy, 9 cases with portal-superior mesentery vein resection with end-to-end anastomosis, 9 cases with portal-superior mesentery vein resection and grafts implantation, 8 cases with concomitant celiac axis resection, 4 cases with concomitant celiac axis and common hepatic artery resection, 1 case with concomitant celiac axis, portal vein and superior mesentery artery resection and reconstruction. Complications occurred in 12 cases (57.1%) post the operation and 5 cases (23.8%) died in 30 days after the operation. Insulin was given at the dose of 18 - 28 U daily post operation and blood glucose was maintained normal effectively. Sixteen cases were followed-up and median survival was 9.2 months (1.2 - 13.0 months). The median survival of tubular adenocarcinoma and intraductal papillary mucinous neoplasms of the pancreas (IPMNs) were 7 months (1.2 - 9.0 months) and 11.3 months (10.0 - 13.0 months), respectively.
CONCLUSIONSTotal pancreatectomy could not improve survival and it increases the complications and death, but it could improve the quality of life. It's an operation of choice for IPMNs, but with pancreatic carcinoma, the warranty of operation should be considered. The blood glucose level could be maintained normal effectively after the operation.

10. Surgical management of concomitant pancreatic neuroendocrine tumors inhereditary tumor syndromes
Chinese Journal of Practical Surgery 2019;39(09):921-925
Pancreatic neuroendocrine neoplasms(pNENs)might present as part of complex hereditary(familial)syndromes caused by germline mutations such as multiple endocrine neoplasia type 1(MEN1),von Hippel-Lindau disease(VHL),tuberous sclerosis,and neurofibromatosis type1(NF1).Increasing knowledge of hereditary pNENs in both their genetic underpinnings and clinical implications has affected the entire spectrum of their surgical management.However,the appropriate surgical timing and management of concomitant pNENs inhereditary tumor syndromes is still debated.
