[Summary] A single-incision video-assisted thoracoscopic sublobular limited resection was performed for a 2-cm pulmonary nodule at the right lower lobe of the lung in August 2014.The post-operative pathological diagnosis was inflammatory myofibroblastic tumor of the lung.No recurrence and metastasis was found after one year’s follow-up.

Objective To investigate main causes leading to conversions to open surgery during laparoscopic cholecystectomy (LC) in the treatment of acute cholecystitis. Methods A total of 32 cases of acute cholecystitis received LC were analyzed. Results Out of the 32 cases of acute cholecystitis, LC was successfully accomplished in 25 cases (78.1%) and a conversion to open surgery was required in 7 cases (21.9%). Major causes of the conversion included the necrosis of the gallbladder(4 cases) and the failure to expose the Calot’s triangle(3 cases). Conclusions Conversions to open surgery should be made during LC when a gangrenous cholecystitis is confirmed or the Calot’s triangle cannot be well exposed.

Objective To evaluate the curative effect of endoscopic sphincterotomy (EST) combined with laparoscopic cholecystectomy (LC) in the treatment of gallstones complicated with common bile duct stones. Methods A total of 36 cases of gallstones complicated with common bile duct stones were enclosed. First EST was performed to remove the bile duct stones. Then LC was applied to resect the gallbladder. Results EST was successfully performed in 34 cases (94.4%) and failed in 2 cases because of the terminal stricture of the bile duct that was afterwards cured by an open choledochojejunostomy. LC was performed following EST in 34 cases, 32 of which were successful (94.1%) and 2 of which required a conversion to open surgery. Conclusions EST combined with LC is the best way for treating gallstones complicated with common bile duct stones. The biliary stricture mainly accounts for the failure of EST and should be treated by choledochojejunostomy as the first choice.

Objective To investigate the effect of antiserum against VEGF on angiogenesis and growth of bladder cancer in a mouse model in order to explore a novel strategy for the treatment of bladder cancer. Methods Antiserum against VEGF was prepared by using recombinant human VEGF and was identified for its specific affinity with VEGF by ELISA.The bladder carcinoma cell lines BST739 were implanted in T739 mice which were randomly divided into 2 groups:the control group receiving normal mice serum intraperitoneally,and the experimental group receiving antiserum against VEGF intraperitoneally.All the animals were sacrificed at last.Then all the bladder carcinomas were weighted and the microvessel density (MVD) in them was studied by immunohistochemical staining. Results The antiserum against VEGF was prepared and demonstrated with high specificity. The MVD in the antiserum group was lower than that in the control group. But the average weight of tumors was not significantly less in the antiserum group. Conclusions The study shows that to inhibit the activity of VEGF may reduce the angiogenesis in bladder cancer and supports the antiangiogenic therapy for bladder cancer.Inhibition of VEGF activity might become an important way of adjuvant therapy for bladder cancer.

Objective To observe the effect of compound traditional Chinese drug on nerve conduction velocity and electromyography in diabetes mellitus patients with diabetic peripheral neuropathy.Method Fifty-seven patients were randomly divided into tow groups.The control group(27 patients)were treated with Vitamin B,and the test group (30 patients)were treated with compound traditional Chinese drug.The never conduction vielocity and electromyography were measured before and after the treatment.Results In the test group,the nerve conductive vielocity was increased and the spontaneous electric potential of electromyography was decreased;whereas,no obvious changes were found in the control group after treatment,and there was significant difference between the two groups(P

Objective To study on effects of Alprostadil on 24-hour urinary albumin(U-Alb)in patients with diabetic nephropathy.Methods:38 patients with diabetic nephropathy were included in the study.The test group involving 20 patients were grouped into group A(pristine diabetic nephropathy) and group B(clinical diabetic nephropathy)randomly according to urinary albumin.The control group including 18 patients were grouped into two groups according to the same way.The subjects in both groups have the same therapy in terms of control of blood glucose,blood pressure,plasma lipids,and other therapy methods.Besides,the test group was injected Alprostadil(凯时)10ug from vein,one time a day,14 day continuously,but Alprostadilas well.Results After the treatment of two groups,the level of the urinary albumin decreased obviously compared with the index before treathent,and decreased significantly compared with normal control group.Conclusion Alprostadil can lower urinary albumin with diabetic nephropathy.

Existing antidepressants exhibit delayed onset of action,which can decrease the compliance of the patients and enhance the risk of suicide.How to produce early-onset antidepressants with higher efficacy and lower adverse reactions has become a crucial point in the research of antidepressants.It has been demonstrated that selective 5-HT1Aantagonist,?2 antagonist and 5-HT2Aantagonist can accelerate the response of classic antidepressants.Furthermore,5-HT/NE dual reuptake inhibitor and 5-HT/NE/DA triple reuptake inhibitor can also produce early onset of action.Here,several reasons for the delayed onset of action and the progress in the development of early-onset antidepressants are reviewed.

Objective To investigate the role of indoleamine 2,3-dioxygenase(IDO)in asthma.Methods The mouse asthma model was induced by ovalbumin(OVA).IDO expression was detected on the level of protein and mRNA respectively.Distribution and maturation of dendritic cells were detected by the immunofluorescence method.Results (1)The symptoms and lung inflammation in the model group were more serious than control group.The serum total IgE was significantly higher in the model group than that in the control group,165.50 ± 30.13 ng/ml vs.94.45 ± 28.30 ng/ml(P ＜ 0.05).(2)IDO expression in the model group was lower than that in control group.On the level of protein,mean intergrated optical density was 11.38 ± 6.05 in the model group vs.23.62 ± 8.92 in the control group(P ＜ 0.05);on the level of mRNA,IDO expression of the model group was 33% of the control group(P ＜ 0.05).(3)CD11c+CD86+ cells were distributed in alveolar wall and around small vessels.The quantity of CD11c+CD86+ cells in lungs of the model group were significantly smaller than that in the control group.The median intergrated fluorescence intensity was 9961.86(range,7 406.52 ～ 12 724.98)in the model group vs.15974.60(range,10 006.39 ～ 16 171.46)in the control group(P ＜ 0.05).Conclusions IDO expression is low and matured dendritic cells are less in situ in the asthma model.These suggest that less matured DCs may produce less IDO,which may play an important role in asthma.

Objective To evaluate the clinical characteristic,diagnosis and treatment procedures for renal oncocytoma and chromophobe cell renal carcinoma.Methods Eight cases of renal oncocytoma and 5 cases of chromophobe cell renal carcinoma were analysed.The average of oncocytoma was 58.8 years old(23～74),and mean tumor size was 5.1 cm(range,3～7 cm);The mean age of chromophobe cell renal carcinoma was 54.5 years old(35～72),and mean tumor size was 5.8 cm(range,3～8 cm).Doppler ultrasonography and CT scan were performed in all patients.All cases accepted surgical operation and were confirmed by pathology.Results Renal oncocytoma was characterized by homogeneous round cell containing aboundant axyphil pellets.Color Doppler ultrasonography show isoechoic or hypoechoic masses.CT scan revealed that the tumors were homogeneous solid masses,and most of them were visualized as homogeneous enhancement.All the patients were followed up for 10 to 53 months,and no recurrence or metastasis was noted.Color Doppler ultrasonography show mainly hyperechoic masses,CT scan revealed most of the tumors were heterogeneous enhancement.All the patients were followed up for 12 to 49 months,and 1 case died from metastasis after 1 year.Conclusion Renal oncocytoma and chromophobe cell renal carcinoma can be differentiated by clinical characteristic,ultrasonic and CT scan examination.The diagnosis is confirmed by pathology.Partial nephrectomy is good for renal oncocytoma,while radical nephrectomy is still the first choice for chromophobe cell renal carcinoma.
