To study the protective effect of astragalus saponin extracts (AS) on kidneys of diabetic rats. Totally 32 diabetic rats induced by streptozotocin (STZ) were divided into AS high and low dose groups, the positive control group and the model group (DM group) and orally administered with 50 mg x- kg(-1) x d(-1) AS 200, 25 mg x kg(-1) x d(-1) valsartan, 10 mL x kg(-1) x d(1) physiological saline, respectively. Another 8 healthy rats were collected in the normal control group (NC group, physiological saline 10 mL x kg(-1). d(-1)). All rats were treated for consecutively 6 weeks. After the administration, the body weight was measured every week, the concentration of blood glucose was monitored on week 2, 4 and 6. The total urine and total urinary protein (U-TP) in 24 h were measured by the metabolic cage method on week 6; At the end of week 6, blood samples were collected from hearts to detect blood urea nitrogen (BUN), serum creatinine (Scr), uric acid (UA) , total cholesterol (CH) triglyceride (TG) by biochemical methods. Kidneys were collect to calculate the kidney hypertrophy index and observe the pathological sections. The laboratory results show that in the DM group, the blood glucose, metabolic cost in 24 h, kidney hypertrophy index, U-TP, BUN, Scr, UA, TG were significantly higher than that in the NC group (P < 0.01, P < 0.05) , with significant pathological changes; After the intervention with AS, the metabolic value in 24 h, kidney hypertrophy index, U-TP, BUN, Scr, UA, TG were significantly lower in the high dose group (P < 0.01, P < 0.05), and the kidney hypertrophy index, BUN, Scr, UA, TG in the low dose group were also significantly lower (P < 0.05), with slight reduction in renal pathological changes in both groups. In conclusion, Astragalus saponin extracts have a certain protective effect on kidneys of diabetic rats.

OBJECTIVETo analyze the long-term results of TIPS, TIPS with coronary vein occlusion (CVO) and combined TIPS and portal azygous disconnection for the treatment of portal hypertension and variceal bleedings.

METHODSThree hundreds and fifty-eight patients with portal hypertension were admitted because of variceal bleeding from July 1993 to May 2008. All patients were divided into 3 groups: 227 cases in group TIPS, 36 cases in TIPS and CVO group, 95 cases in combined TIPS and portal azygous disconnection group. The rates of successful operation, shunt patency, rebleeding, encephalopathy and survival were observed and compared by statistics methods.

RESULTSThere were 349 cases (97.5%) underwent successful surgery and 9 cases with failure surgery. The rates of occluded shunts, encephalopathy, rebleeding, and death in early periods were 2.5%, 31.8%, 4.7% and 9.0% respectively. The rate of encephalopathy and death in group with TIPS were higher than in group with combined TIPS and portal azygous disconnection (P < 0.01). The rate of encephalopathy and death were 41.2% and 24.7% in 85 cases with emergency TIPS. During the follow-up 1 - 15 years, the rate of patency shunts in 12 and 24 months after operation was 74.0% and 48.1% respectively. The rate of 1-year patency shunts in group with combined TIPS and portal azygous disconnection was higher than in group with TIPS, TIPS and CVO (P < 0.01 and P < 0.05). The rebleeding in group with TIPS was higher than in group with combined TIPS and portal azygous disconnection (P < 0.01), and the survival rate in group with TIPS was lower than in group with TIPS and CVO, combined TIPS and portal azygous disconnection (P < 0.01 and P < 0.01).

CONCLUSIONSTIPS is an efficient therapy for portal hypertension with CVO, combined TIPS and portal azygous disconnection can improve the results of TIPS for portal hypertension.

OBJECTIVETo analyze the influence of included angle between the anterior aspects of S2 and S vertebral bodies on pelvic inlet imaging in the pelvic midline sagittal plane.

METHODSTotally 58 axial pelvic CT scans were chosen as study objects including 43 males and 15 females,with an average age of 40.7 years old (ranged,18 to 68 years old). The angles between the anterior aspects of S2 and S1, vertebral bodies and the horizontal plane on midline sagittal CT reconstruction were measured to simulate the optimal S2 and S1 inlet angles. The included angle between the anterior aspects of S2 and S1 vertebral bodies was calculated by subtrocting the S1,inlet angle from the S2 inlet angle defined as a base number. Then, the impact of the calculated included angles on the pelvic inlet imaging was analyzed. Results:The S2 inlet angles averaged (30.5±6.5) degrees; the S inlet angles averaged (25.7±5.9) degrees. The difference between them was significant (t=3.35, P=0.001). Ten patients had zero angle between the anterior aspects of S2 and S1 vertebral bodies; 14 patients had negative angle, averaged-(8.9±8.1) degrees; 34 patients had positive angle,averaged (11.8+6.4) degrees.

CONCLUSIONThe difference of included angle between the anterior aspects of S2 and S1 vertebral bodies leads to the difference between S1 inlet view and S2 inlet view in most cases, complicating the pelvic inlet imaging,and affecting the reliability of the application of pelvic inlet view. Utilizing the angles measured on the preoperative midlihe sagittal CT reconstruction to obatin the patient-customized S1 and S2 inlet views could accurately guide the S1 and S2 iliosacral screw insertion.

OBJECTIVETo examine the outcome of damage control surgery (DCS) in patients with acute mesenteric ischemia (AMI).

METHODSClinical data of 15 consecutive AMI cases treated with DCS from May 2001 to March 2009 at the Research Institute of General Surgery, Jinling Hospital were retrospectively analyzed. Eleven patients had acute superior mesenteric vein thrombosis (MVT) on admission, and 4 suffered from acute mesenteric arterial embolism/thrombosis (MAE/MAT). The staged damage control approach included immediate resection of the involved bowel (but no attempts to restore gastrointestinal continuity), open thrombectomy, transfer of the patients to ICU for resuscitation, and thrombolysis prior to the planned definitive reconstructive procedure.

RESULTSOf 15 patients, 10 (66.7%) survived. The mean remnant small bowel length was (209.0+/-53.8) cm (120 to 280 cm). None of the survived patients was parenteral nutrition-dependent. Of the 5 deaths, 2 died of recurrence of thrombosis and necrosis of the remaining bowel,1 of massive gastrointestinal bleeding. One patient abandoned treatment intra-operatively, and another with total small bowel resection abandoned treatment postoperatively.

CONCLUSIONSDamage control approach improves the survival of patients with AMI. Thrombectomy and thrombolysis are necessary for AMI management to prevent progression or further development of the thrombosis.

OBJECTIVETo summarize the clinical experience and to evaluate the safety and technical characters of laparoscopy-assisted total/subtotal colectomy(LAC).

METHODSFrom June 2005 to May 2008, a total of 150 cases underwent LAC in Jinling Hospital. There were 126 cases of severe functional constipation (SFC) treated by LAC combined with modified Duhamel procedure. There were 11 cases of familial adenomatous polyposis, 8 cases of ulcer colitis and 5 cases of multiple colorectal tumors treated with LAC combined with ileum-rectum anastomosis.

RESULTSOf the 150 cases, LAC was successfully performed in 147 cases. The mean operation time of LAC was (76.0+/-23.5) min. The estimated operative blood loss was (35.4+/-10.9) ml. The length of assisted incision was (5.2+/-1.1) cm. The time to resume intestinal function was (42.5+/-12.6) h. There was no postoperative wound infection, anastomotic stoma and other complications. Within 1 week after operation, severe diarrhea occurred in 2 cases and incomplete small bowl obstruction in 2 cases, who were relieved by conservative treatment. The mean postoperative hospital stay in patients without complication was(7.2+/-1.5) d. One year later, the score of gastrointestinal index quality of life in 116 patients was (110.3+/-20.7), which was significantly elevated as compared with the pre-operation score (90.1+/-23.8) and was not significantly different with the healthy score. The constipation symptoms were released in all the 105 SFC patients with different degree diarrhea in 7 cases and recurrence of mild constipation in 4 cases. There was no sign of recurrence and metastasis in 3 cases of multiple colorectal tumors.

CONCLUSIONSLAC embodies the advantages of less invasiveness of laparoscopy. It is a reasonable choice of operation method in treating various diseases related to total colon.

OBJECTIVETo determine the outcome of hepatic venousaplasty and transjugular intrahepatic portosystemic shunt (TIPS) in the treatment of the Budd-Chiari syndrome with occlusion of the hepatic veins.

METHODSFifty patients of the Budd-Chiari syndrome with occlusion of the hepatic veins (23 males and 27 females, with a mean age of (39 ± 11) years) were elected for venousaplasty or TIPS. The average of Child-Pugh scores was 9.6 ± 2.6. Three patients had a acute course of the disease, while 47 patients had a subacute or a chronic course of the disease. The clinical presentation was ascites in all 50 cases, with concomitant upper gastrointestinal bleeding in 10 patients, hepatorenal syndrome in 4 patients and impaired liver function in all patients. Hepatic venousplasty was performed for 12 patients with occlusion of hepatic venous. Hepatic and inferior caval venousplasty were performed for 6 patients with occlusion of hepatic and inferior caval vein. TIPS was performed for 13 patients with occlusion of small hepatic vein. Modified TIPS was performed for 19 patients with extensive occlusion of hepatic vein.

RESULTSThe procedure of treatment was successfully performed in all patients. The shunt reduced the portosystemic pressure gradient from (41 ± 10) to (27 ± 6) cmH2O (1 cmH2O = 0.098 kPa, t = 20.20, P = 0.001) and improved the portal flow velocity from (14 ± 10) to (52 ± 14) cm/s (t = 15.02, P = 0.001) after TIPS or modified TIPS. Clinical symptoms and the biochemical test results improved significantly during 3 weeks after hepatic venousplasty and shunt treatment. During the hospitalization, the death occurred in 1 case due to hepatic failure and the acute occlusion of shunt was treated with secondary intervention in another case. The mean follow-up was (82 ± 46) months. The revisions of shunt with TIPS were needed in 2 patients and the inflation of stenosised hepatic vein in another 2 patients during the follow-up. All patients were still observed.

CONCLUSIONHepatic venousaplasty and TIPS provide an excellent outcome in patients of Budd-Chiari syndrome with occlusion of the hepatic veins.

OBJECTIVETo investigate the exposure levels of carbon disulfide (CS(2)) for a chemical fiber industry.

METHODSThe concentration of CS(2) was monitored in representative workshops and types of work, and the datas of that over the years were collected.

RESULTSThe short-term exposure concentration of CS(2) about 80% of the type of work was less than or equal to 10 mg/m(3), which of more than 90% was less than or equal to 20 mg/m(3). The time weighted average concentration of CS(2) about 70% of the type of work was less than or equal to 5 mg/m(3), which of more than 90% was less than or equal to 10 mg/m(3). The short-term exposure concentration of CS(2) which was more than 15 mg/m(3) or the time weighted average concentration of CS(2) which was more than 30 mg/m(3) was only for little type of work.

CONCLUSIONThe concentration of CS(2) for the most type of work was lower, but there were still a number of types of work exposuring the higher concentration, which exceed the national occupational exposure limits.
