Objective To investigate the conditions of family function of rehabilitative breast cancer patients and its related factors. Methods Self-administrated questionnaire and the family APGAR (adaptation, partnership, growth, affection, resolve) index questionnaire were used in 245 breast cancer patients to investigate their general and illness information, and their family APGAR index. The factors relat-ed with the family function of breast cancer patients were analyzed. Results The APGAR score of the participants was (7.51±1.17), and the condition of family was graded from good (73.5%), moderate impairment (21.2%) to severs impairment (5.3%). The multiple regression analysis found that the stage of the disease (β=-9.671), the condition of marriage (β=8.29) and their social activities (β=7.402) related with the APGAR index in rehabilitative breast cancer patients. Conclusion The family function needs attention, especially the metastasis ones in breast cancer patients. A healthy marriage and beneficial socialization contribute to keep good family function.

Objective To investigate the effects of gastric bypass on glycometabolism and improvement of islet β cell function and insulin resistance in patients with type 2 diabetes. Methods Eight patients with type 2 diabetes combined with gastric carcinoma who treated with gastric bypass were studied prospectively. Fasting and postprandial plasma glucose levels, fasting and postprandial insulin C-peptide levels, and body mass index (BMI) were measured right before the surgery and at intervals of 1 week, 2 weeks, 1 month and 3 months after the surgery. Glycosylated hemoglobin (HbA1c) levels were measured before and 3 months after the surgery. The outcome of the diabetes after 3 months of the surgery was also monitored. Results Fasting and postprandial plasma glucose levels decreased (P ＜ 0.05) and fasting and postprandial insulin C-peptide levels increased (P ＜ 0.05) after the surgery. HbA1c levels also decreased (P ＜ 0.05) after 3 months of the surgery. There was no significant change of BMI at all intervals after the surgery(P＞ 0.05). All of the 8 patients reached the total effective standard and 6 patients reached the clinical remission standard after 3 months of the surgery. Conclusions It suggests that gastric bypass can significantly lower plasma glucose levels in type 2 diabetes, which does not depend on the loss of weight. The control of plasma glucose by gastric bypass may be due to the improvement of islet β cell function and increasing secretion of endogenous insulin.

Methods One hundred and seven DVT patients receiving VenaTech LP permanent IVCF implantation from October 2005 to November 2009 were selected. In hospital and following up data were analyzed. Results All the filters were successfully implanted. No symptomatic PE took place during acute stage of thrombosis after filter implantation. No complication took place during following up 1 to 36 months.Conclusion Implantation of VenaTech LP permanent IVCF is safe and effective in the prevention of PE.

Objective To investigate the mechanism of endothelin (ET) in acute biliary pancretitis (ABP)with renal impairment, and examine the improvement of renal function by puerarin. Methods Thirty-two patients of ABP with renal impairment were selected and were randomly divided into group A and group B. Group A were given puerarin post-operatively, while group B were given common manegement postoperatively. Meanwhile, 16 ABP patients without renal impairment were selected as group C, and 16 nonABP patients who had common hepatic or biliary diseases were selected as group D. The levels of plsma ETand creatinine clearance rate(Ccr) of renal function in each group were observed pre-operation and 1 week post operation. Results In pre-operation the ET level in group A, B and C were higher than in group D(P ＜0.001), and the ET level in group A,B was higher than in group C(P＜0.001). Post operation after I week the ET level in group A was lower than in group B(P =0.014), while the Ccr level in group A was higher thanin group B ( P = 0.002). Conclusions The function of endothelin is an important mechanism in biliary pancretitis with renal impairment. Puerarin might reduce the ET level and increase the Ccr level in patients of ABP with renal impairment, improve the renal function of such patients.

Objective To develop a method of adult porcine pancreatic islet isolation.Methods The tails of adult porcine pancreas were perfused through the pancreatic duct with 0.1% cold collagenase(type Ⅺ) and incubated at 38.5 ℃.The digested tissue was dispersed in 4 ℃ Hanks balanced salt solution(HBSS).The tissue suspensions were filtered through a 600 ?m mesh.The residual tissue was resuspended in cold HBSS,and put in the Ricordi’s chamber and shaken for 5 minutes,then filtered again.The isolated islets were divided into three groups: control group( n =14),Pefabloc(trypsin inhibitor, n =8) group and FOY(trypsin inhibitor, n =5) group.The collagenase solution of the Pefabloc and FOY group was supplemented with 1.0 mmol/L Pefabloc and FOY respectively. Results The islet yields of the Pefabloc group and FOY group 〔(11 848?3 530) islet/g pancreas and (14 496?3 693) islet/g pancreas〕 were significantly higher than that of the control group 〔(8 505?3 349) islet/g pancreas〕, P

OBJECTIVETo regain bile excretory function of hepatocytes cultured in vitro.

METHODSSandwich configuration was used to culture hepatocytes and the structure of bile canaliculi as well as the function of bile excretion was observed by immunocytochemistry and the test of FDA metabolism with a single collagen configuration as a control.

RESULTSFirst, the formation of bile canaliculi was observed by immunocytochemistry. In sandwiched hepatocytes, the gradual development of bile canaliculi-like structures into an anastomotic network was observed. At 24 h after cell culture, the formation of bile canaliculi was observed. With time progressed, the bile canaliculi became more clear and the network was established at 120 h. In contrast, hepatocytes in single collagen configuration showed almost no network of bile canaliculi. Second, the ability for hepatocytes to internalize, metabolize and excrete compounds into bile was indicated by FDA metabolized in the hepatocytes. In sandwiched hepatocytes, the bile excretory function was shown at 96 h, but in single collagen system, no bile excretion was observed.

CONCLUSIONCultured hepatocytes are able to regain bile excretion in a given certain condition. Sandwich-cultured hepatocytes can reestablish bile canalicular structure and regain bile excretory function.
