Objective To study the use of early bile duct to bile duct end-to-end(side) anastomosis for extrahepatic bile duct injuries.Methods The clinical data of 25 patients with extrahepatic bile duct injuries with early bile duct to bile duct end-to-end(side) anastomosis were retrospectively analyzed.Results Bile duct injuries happened in laparoscopic cholecystectomy (n=17),laparoscopic exploration of common bile duct (n=1),laparotomy (n=5),and knife wound (n=2).All of the repairs were successfully carried out.Except for one patient who was lost to follow-up,the other patients were followed for over 2 years.There was no bile duct stenosis.One patient died after 5 months of repair in other hospital because of a recurrent bile duct calculus.Conclusions Early bile duct to bile duct end-to-end(side) anastomosis had a good long-term results.The operation needs to be done by a good surgeon or supervised by an experienced specialist in biliary surgery.A prolonged period of T tube stenting is a prerequisite for success.

BACKGROUND: Presently, it is a certain preventive effect of local emplacement of various isolated materials during operation and postoperatively drug-controlled inflammatory reaction on adhesion between epidural and nerve root after laminectomy.OBJECTIVE: To study the preventive effect of chitosan and titanium net on epidural cicatricle adhesion after laminectomy.DESIGN, TIME AND SETTING: Randomized controlled animal study, which was performed in Guiyang Medical College from June to December 2005.MATERIALS: Eighty adult rabbits, weighing (2.0±0.2) kg, were used to establish vertebral plate resection models. Chitosan was provided by Shanghai Qisheng Biological Agent Industry Company, and titanium net by Guizhou Kelun Pharmacology Company Limited.METHODS: Eighty adult rabbits were randomly divided into four groups, including control group (0.5 mL saline), titanium net group (titanium net in the size of 1.0 cm × 0.8 cm was covered on defect region of vertebral plate and fixed on processus spinosus of upper and lower cone, bilateral muscles and soft tissues), chitosan group (2 mL chitosan), and chitosan + titanium net group (combination of chitosan and titanium net). Six rabbits were sacrificed in the 2nd and 4th weeks postoperatively, and eight rabbits were chosen as the samples in the 8th week.MAIN OUTCOME MEASURES: Morphological changes of cicatricle.RESULTS: Cicatricle was clearer in the control group. Titanium net could relieve peripheral cicatricle of dura mater and effectively isolate peripheral cicatricial tissue and spinal dura meter. Chitosan could remarkably prevent from cicatricle adhesion and inhibit inflammatory reaction. The combination of chitosan and titanium net could effectively inhibit proliferation of cicatricle surrounding dura meter.CONCLUSION: Association of chitosan and titanium net can effectively inhibit cicatricle adhesion surrounding dura meter after laminectomy.

Percutaneous nephrostomy was applied in some other urologic diseases and the efficacy was evaluated. Percutaneous nephrostomy for percutaneous nephrolithotomy (PNL) was performed in patients with various renal, perinephric and bladder diseases (n=79). The tract establishment, operation duration and complications were observed and the efficacy was assessed. The results showed that the tracts were successfully established in 79 cases. The operation lasted 4-20 min. 12F-16F single tract was established in nephrohydrop patients and 16F-20F single or multiple tracts were established in patients with pyonephrosis, renal cortical abscess, renal cyst and perinephric abscess. During dilation, no leakage of liquor puris was noted. Establishment of 18F single tract was achieved in one urinoma patient. In two patients with foreign body in kidney, the foreign bodies were removed via established 14F single tract. 18F tracts were established in 2 patients with bladder contracture, which was followed by the placement of 16F balloon urethral catheter for drainage. No complications, such as massive bleeding, intestinal injury and spreading of infection took place in our series. All the patients were followed up for 2-12 months. No long-term complications such as dropping of drainage tube occurred. It is concluded that as a minimally invasive technique, percutaneous nephrostomy has the advantages of convenience, simplicity and causing less complications and can be used for various urologic diseases.

Objective To evaluate the clinical efficacy of berberine for the treatment of insulin resistance (IR) in women with polycystic ovary syndrome (PCOS).Methods Sixty PCOS-IR women were randomized into treatment group and control group,30 cases in each group.At the end of the trial,26 cases in the treatment group (4 cases dropped out) and 29 cases in the control group (one case dropped out) completed the trial.The treatment group was treated with berberine orally,and the control group was treated with metformin orally,the treatment for the two groups lasting 3 months.Before and after treatment,we observed the parameters of body mass index (BMI),homeostasis model of assessment for insulin resistance index (HOMA-IR),fasting plasma glucose (FPG),fasting insulin (FINS),2-hour postprandial glucose after oral glucose tolerance test (OGTT2hPG) and 2-hour postprandial insulin after OGTT (OGTT2hINS),blood lipid levels of total cholesterol (TC),triglyceride (TG),low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C),and sexual hormones of follicle-stimulating hormone (FSH),luteotropic hormone (LH),testosterone (T) and LH/FSH ratio.Results BMI,HOMA-IR,TC,TG and LDL-C of the two groups were decreased after treatment (P ＜ 0.05 or P ＜ 0.01 compared with those before treatment),but the differences between the two groups were insignificant(P ＞ 0.05).Serum levels of T and LH as well as LH/FSH ratio in the treatment group were also decreased (P ＜ 0.05 or P ＜ 0.01 compared with those before treatment and those in the control group after treatment).Conclusion Berberine can improve HOMA-IR,decrease serum sexual hormones levels,and regulate the blood metabolism in PCOS-IR women,and its effect is similar to that of metformin.

Astract: Objective To explore the efifcacy and safety of endoscopic tissue adhesive injection in treatment of gastric variceal bleeding from liver cirrhosis.Methods Object of study are 92 cirrhotic patients (72 male/20 female) in hospital, who had been diagnosed with gastric varices bleeding from June 2014 to May 2016. Child-Pugh score at presentation for cirrhotic patients was A-28; B-36; C-28. According to endoscopic classiifcation of gastric varices, GEV1 were detected in 80 patients, GEV2 in 12. All patients were treated with endoscopic hypertonic glucose tissue adhesive ‘sandwich’ injection.Result Successful injection rate was 100.0% in 92 patients, among which 40 patients had accepted emergency endoscopic treatment and the immediate hemostasis rate was 100.0%. 65 patients were Having gastroscope review after the injection six months, 22 patients were significantly effective, accounting for 33.8%; 38 patients were effective, accounting for 58.4%; 5 patients were invalid, accounting for 7.7%. All the patients were followed up in 1 to 24 months. The late-rebleeding rate was 2.2%. None of them were having early-rebleeding or dead; Complications the incidence of rebleeding rate which caused by removing the needles which trapped in the varices was 2.2%. The incidence of chest pain rate was 4.3%, the bloating rate was 6.5% and the ulceration rate was 15.2%. There was no complications like fever, infection, stomachache, embolism and so on.Conclusion With low rebleeding rate and light side-effect, endoscopic tissue adhesive injection in the treatment of gastric variceal bleeding caused by cirrhosis portal hypertension has really good effect.

BACKGROUND:Studies have demonstrated that tetrandrine has protection on acute spinal cord injury,but the specific mechanism remains poorly understood.OBJECTIVE:To study the protection of tetrandrine on rat acute spinal cord injury and to study its mechanism from apoptosis pathway.METHODS:A total of 100 rats were randomly divided into 4 groups.All rats were prepared for spinal cord injury models using modified Allen method except that in the sham-surgery group.Methylprednisolone and tetrandrine was injected into rats in the methylprednisolone and tetrandrine groups by tail intravenous injection prior to and at 24,48 hours after model preparation.The same volume of physiological saline was injected in the sham-surgery and model groups.Basso-BeatUe-Bresnahan(BBB score)was recorded at 8 hours,1,3,7 and 14 days after model preparation.The morphological changes of spinal cord injury sites were observed by hematoxylin-eosin staining and the expressions of bcl-2 and bax were determined by immunohistochemistry.RESULTS AND CONCLUSION:The BBB score of methylpradnisolone and tetrandrine groups were significantly higher than that model group at 7 and 14 days(P<0.05),but there were no significant difference between the methylprednisolone group and tetrandrine group(P>0.05).Hematoxylin-eosin staining showed that the spinal cord injured severely at 3-7 days,the injury degree in the methylpradnisolone group and tetrandrine group was slighter than that of the model group,with smaller bax expression and greater bcl-2 expression(P<0.01).The findings demonstrated that,tetrandrine is able to protect neurons from apoptosis and promote the nerve function recovery by inhibiting the expression of Bax and promoting the expression of Bcl-2.Its effect is not inferior to methylprednisolone.

Objective To discuss the therapeutic options for treatment of subaxial cervical dislocation combined with facet locking. Methods There were 49 patients with cervical dislocations including 7 patients with dislocation at C3,4, 15 at C4,5, 14 at C5,6 and 13 at C6,7. Eleven patients were with old dislocation, with duration of dislocation ranging from 2 hours to 61 days. Neurologic status of the patients according to Frankel scale was graded A in 14 patients, grade B in nine, grade C in 10 and grade D in nine. All patients were treated surgically after closed reduction with skull traction. Results The successful reduction rate was 63% for fresh dislocation, with average improvement of 0.65 grade for spinal cord function. All bone grafts got fusion at four months after operation. Conclusion Therapeutic options are based on fresh or old dislocations, paraplegia or not, intervertebral disk injury severity, and reduction or not through traction for patients with lower cervical dislocations.

Objective To evaluate the effect of low-dose ketamine on the efficacy of electroconvulsive therapy (ECT) under propofol anesthesia in depressed rats. Methods Sixty adult male SD rats weighing 200-250 g were used in this study. The depression model was established by chronic unpredictable mild stress (CUMS). The animals were then randomly divided into 6 groups (n = 10 each): control group (group C), depression group (group D), propofol group ( group P), propofol + ECT group ( group PE), ketamine + propofol group ( group KP), and ketamine + propofol + ECT group (group KPE). Groups P and KP received intraperitoneal propofol 100 mg/kg and ketamine 10 mg/kg + propofol 80 mg/kg respectively, and groups PE and KPE received ECT after intraperitoneal injection of propofol 100 mg/kg and ketamine 10 mg/kg + propofol 80 mg/kg respectively once a day for 7 consecutive days. All rats underwent sucrose fluid consumption and Morris water maze tests before CUMS, after CUMS, and after treatment. Results Compared with group C, the sucrose consumption percentage was significantly decreased, the escape latency was prolonged, and the time spent in the target quadrant (the original platform quadrant) was shortened after CUMS in D, P, PE, KP and KE groups ( P ＜ 0.05). Compared with group D,the sucrose consumption percentage was significantly increased (P ＜ 0.05), while no significant change in the escape latency and time spent in the target quadrant was found after treatment in group KPE ( P ＞ 0.05 ), and the sucrose consumption percentage was significantly increased, the escape latency was prolonged, and the time spent in the target quadrant was shortened after treatment in group PE ( P ＜ 0.05). Compared with group PE, the sucrose consumption percentage was significantly increased, the escape latency was shortened, and the time spent in the target quadrant was prolonged after treatment in group KPE ( P ＜ 0.05). Conclusion Low-dose ketamine can not only enhance the efficacy of ECT under propofol anesthesia in depressed rats, but also reduce cognitive impairment induced by ECT.

ObjectiveTo investigate the effect of propofol on cyclooxygenase-2 (COX-2) expression in hippocampal neurons in depressed rats after electroconvulsive therapy (ECT).MethodsFifty 2-3 months old male SD rats weighing 200-250 g were randomly divided into 5 groups (n =10 each):group control (group C) ; group depression (group D); group propofol (group P); group ECT (group E) and group propofol + ECT (group PE).Depression was induced by separation and chronic unpredictable mild stres in groups D,P,E and PE.Groups P and PE received intraperitoneal pro pofol 80 mg/kg.Groups E and PE received ECT at 5 min after IP normal saline 8 ml/kg and propofol 80 mg/kg respectively once a day for 7 consecutive days.The learning and memory function was assessed by using Morris water maze test before (baseline) and after depression was induced and ECT.The animals were then sacrificed and their brains removed for detection of COX-2 mRNA expression in hippocampus (by RT-PCR).Results In group D depression significantly prolonged evasive latency and decreased swimming time percentage in platform quadrant and up-regulated COX-2 mRNA expression as compared with group C.In group E ECT further prolonged evasive latency and up-regulated COX-2 mRNA expression in depressed rats.In group PE propofol pretreatment attenuated ECT-induced impairment of learning-memory function and increase in COX-2 mRNA expression as compared with group E.ConclusionPropofol can ameliorate the decrease in learning and memory function induced by ECT in depressed rats by inhibiting COX-2 expression in hippocampal neurons.
