Objective To investigate the clinical value of video-assisted thoracoscopic surgery (VATS) in the treatment of lung cancer. Methods The study included 49 patients with non-small cell lung cancer at stage Ⅰ~Ⅱ from January 2005 to June 2006. Lobectomy with mediastinal lymph node resection was performed by using VATS in 22 patients (Thoracoscopic Group) and by using conventional surgery in 27 patients (Conventional Group). The pulmonary functions and levels of C-reactive protein (CRP) were compared between the two groups. Results In the Thoracoscopic Group, a conversion to thoracotomy (12~15 cm of incision length) was required in 2 patients for treating blood vessels safely. The concentrations of CRP rose to the highest on the first day in both of groups. As compared with the Conventional Group, the CRP levels were significantly lower in the Thoracoscopic Group on the first day (56.1?10.9 mg/L vs 73.8?15.1 mg/L; t=-4.603, P=0.000). At 1 week after operation, the Thoracoscopic Group presented significantly lower minute ventilation volume (MV) (95.6?16.4 L vs 81.9?12.7 L; t=3.296, P=0.002) and forced expiratory volume in one second (FEV_1%) (51.7?5.7% vs 51.4?6.9%; t=3.105, P=0.003) than the Conventional Group. Conclusions VATS can be routinely adopted in patients with lung cancer at stage I or Ⅱ, with lesion

Objective To confirm the protective effect of berberine (BBR) on cold ischemia reperfusion (I/R)-induced liver injury and to show whether the hepatic protection conferred by BBR involves the activation of phosphatidylinositol 3 kinase (PI3K) / protein kinase B (Akt)/mammalian target of rapamycin(mTOR) signal pathway.Method Adult male Sprague-Dawley rats were assigned randomly to four groups:BBR group (BBR was intragastrically administered at a dose of 100 mg·kg-1 · d-1 2 weeks before hepatic cold I/R treatment),dimethyl sulfoxide (DMSO) group (BBR was replaced by DMSO,and others were the same as BBR group),I/R group (BBR was replaced by normal saline,and others were the same as BBR group) and sham group (normal saline was administered 2 weeks before opening and closing abdomen treatment).Then the rats were sacrificed at 3,6,and 24 h after reperfusion.The liver function,oxidative stress level,apoptosis rate,and the expression of PI3K/Akt/mTOR related pathway proteins were assayed.Result As compared with sham group,the I/R-induced liver tissue displayed severe lobular distortion with widespread necrosis,high level of oxidative stress and apoptosis rate.As compared with I/R group,BBR dramatically attenuated the histopathologic damage,restored the liver function and decreased the oxidative stress level.Simultaneously,BBR significantly ameliorated the apoptosis by decreasing the apoptosis rate,increasing the Bcl-2/Bax ratio and inhibiting caspase-3 activity in rats subjected to hepatic I/R.The expression of p-Akt was effectively upregulated with the inhibited expression of p-mTOR.Conclusion Our result provides robust in vivo evidence that BBR can prevent I/R-induced oxidative stress and apoptosis.The mechanisms involved can be attributed to the activation of P]3K/Akt/mTOR signal pathway.

Objective To evaluate the influence of antiplatelet therapy prior to intravenous thrombolysis (IVT) on acute ischemic stroke (AIS) patients receiving IVT with recombinant tissue type plasminogen activator (rt-PA).Methods Researches about the safety of pre-existing antiplatelet treatment on AIS patients undergoing rt-PA IVT published before 31st December 2013 were retrieved based on internet databases.A meta-analysis of included clinical trials was performed by RevMan 5.2 and Stata 12.0 software.Simultaneously,funnel plot and Egger's test were used to evaluate the publication bias.Results A total of 10 papers were included.Eight researches based meta-analysis showed that pre-existing antiplatelet therapy increased the risk of symptomatic intracranial hemorrhage (SICH ; OR =1.67,95％ CI 1.44-1.93,P ＜ 0.01),6 researches based analysis suggested pre-existing antiplatelet therapy increased the risk of any intracranial hemorrhage (ICH ; OR =1.23,95％ CI 1.04-1.47,P ＜ 0.05) and 3 trials based analysis indicated the functional independence of patients receiving antiplatelet treatment was a bit worse than control group (OR =0.86,95％ CI0.80-0.93,P ＜0.01).Funnel plots and Egger' s test showed that there was no significant publication bias (P ＞ 0.05).Conclusions Antiplatelet therapy might increase the risk of post thrombolysis SICH and ICH,and their 3-month function independence is not so satisfied as those who had no antiplatelet agents before IVT.However,this review has limitations and the above results should be validated in future large prospective clinical studies.

BACKGROUND: Glucose metabolism disturbance, one of clozapine's adverse effects, has received increasing attention from endocrinologists. Insulin resistance is believed to be associated with clozapine-induced glucose metabolism disturbance. Does it have direct effects on secretion function of islets?OBJECTIVE: To investigate the effects of different concentrations of clozapine on the secretion function of pancreatic islets in vitro.DESIGN: A completely randomized controlled design for the experimental study.SETTING: Department ofPsychiatry, People's Hospital of Wuhan University.MATERIALS: The experiment was conducted in the Laboratory Center of Stomatology Hospital of Wuhan University from September 2003 to January2004. Three healthy male Wistar rats of clean grade were used.METHODS: [1] Classical collagenase digestion method was used to isolate and purify the rat islets of Langerhans. [2] Hank's solution containing 2 g/L bovine serum albumin and 3.3 mmol/L glucose was added for preincubation for 30 minutes. The supernatant was removed. The wells were divided into five groups with 12 wells in each group. The control group was added with 1 g/L dimethyl sulphoxide (DMSO) and 3.3 mmol/L or 16.7 mmol/L glucose, 1 mL per well. The four experimental groups were added with 1 mL 0.2 μmol/L, 1 μmol/L, 5 μmol/L, or 10 μmol/L clozapine apart from the above DMSO and glucose. Six wells in each group were incubated for 1 hour, and another six wells were incubated for 4hours. The supernatants of the different groups were collected and stored at-20℃ in the refrigerator for later testing. The above procedures were repeated three times. The insulin released into the medium supernatant was examined by radioimmunoassay. [3] One-way ANOVA was used to compare the differences between the experimental groups and control group; LSD-t test was used for multiple comparison.MAIN OUTCOME MEASURES: The level of insulin secretion in the supernatants in culture solution containing 3.3 mmol/L or 16.7 mmol/L glucose which was incubated for 1 hour or 4 hours.RESULTS: [1] At 3.3 mmol/L glucose, no difference in insulin secretion was found between the four clozapine groups and control group after 1-hour incubation (P ＞ 0.05). After 4-hour incubation, the level of insulin in clozapine groups decreased significantly [(0.92±0.4), (1.02±0.3),(1.06±0.4), (0.74±0.2), (1.66±0.4) mU/IEQ, P ＜ 0.05]. There was no significant difference in the volume of insulin among the four clozapine groups with different concentrations (P ＞ 0.05). [2] At 16.7 mmol/L glucose, the level of insulin at the four concentrations of clozapine did not differ from that of control group either after 1 hour or 4 hours of incubation (P ＞ 0.05).CONCLUSION: Clozapine inhibits basal insulin secretion, but the effect is not correlated with its dosage.

Objective To evaluate the role of autophagy in the development of neuropathic pain (NP) in rats.Methods Thirty male Sprague-Dawley rats,weighing 200-220 g,were randomly divided into 3 groups (n =10 each) using a random number table:sham operation group (sham group),NP group and rapamycin (autophagy inducer) group (Rap group).Intrathecal catheter was inserted into the subarachnoid space and advanced caudally until the tip reached L4,5 segment.NP was induced by ligation of the left L5 spinal nerve (SNL) in NP and Rap groups.The L5 spinal nerve was only exposed,but not ligated in group sham.At 30 min before ligation and 2 days after operation,rapamycin 60 μg was injected intrathecally via the intrathecal catheter in Rap group,while the equal volume of vehicle (5％ dimethyl sulfoxide) was injected in sham and NP groups.The mechanical and thermal pain thresholds were measured on 1,3,5 and 7 days after ligation (T-4).The rats were sacrificed after the last measurement of pain threshold at T4.The ipsilateral L5 segment of spinal dorsal horn was removed for examination of autophagosomes (using transmission electron microscope) and for determination of the expression of LC3 Ⅱ and p62 (by Western blot) and content of IL-1β (by ELISA).Results Compared with sham group,the mechanical pain threshold at each time point and thermal pain threshold at T2-4 were significantly decreased,and the LC3 Ⅱ and p62 expression and IL-1β content were increased at T4 in group NP (P ＜ 0.05).Compared with NP group,the mechanical pain threshold at each time point,thermal pain threshold at T2-4 and LC3 Ⅱ expression at T4 were significantly increased,and the p62 expression and IL-1β content were decreased at T4 in group Rap (P ＜ 0.05).Microscopic examination showed that autophagosomes were observed in the spinal dorsal horn in NP and Rap groups,and the damage to organelles was lighter in Rap group than in NP group.Conclusion The development of NP is related to autophagic dysfunction in rats.

Objective To investigate the effects of allogenic intra-bone marrow bone marrow transplantation (IBM-BMT) on re-establishing hematopoiesis in mice. Methods Bone marrow mononuclear cells (BMNCs) from BALB/ c mice were transplanted into the C57BL/6 mice treated with a lethal dose of ~(60)Coγ-ray radiation through intra-bone marrow injection or intravenous injection. Sixty of the C57BL/6 mice were randomly divided into three groups as higher dose intra-bone marrow injection group (IBM1 group), lower dose intra-bone marrow injection group (IBM2 group) and intravenous injection group (IV group). The nucleated cell numbers of whole bone marrow from the tibia of each recipient mouse were counted respectively at the day 1, day 3, day 6 and day 9 after the transplantation. The donor-derived total nucleated cells and myeloid cells were quantified by flow cytometry. Results At 6th day after transplantation, more total bone marrow nucleated cells, total donor-derived nucleated cells and donor-derived myeloid cells in the tibia of injected side in both IBM1 group and IBM2 group were found than that in IV group (P<0.05 or P<0.01). Conclusion Compared with traditional bone marrow transplantation (IV-BMT),IBM-BMT improves the bone marrow hematopoiesis in the early hematopoietic re-establishing stage in allogenic bone marrow transplantation.

Objective To study the clinical meaning of Transgelin expression in heptacellular carcinoma(HCC) in prognosing recurrence after hepatectomy. Methods The expression of Transgelin in cancerous lesions and tissue adjacent to cancer lesions from 223 operation samples was detected by immunohistochemical staining combined with tissue microarray techniques. The correlation between the level of Transgelin expression and the prognosis was analyzed by means of log- rank test, Kaplan- Meier analysis and multivariate Cox regression analysis. Results Transgelin was higher expressed in tumor tissue than in tissue adjacent to cancer lesions. Transgelin was positively correlated with the presence of tumor size, portal vein invasion, pTNM tumor stages and serum AFP level. Patients with positive expression of Transgelin had worse tumor free survival than those with negative ones (P ＜0. 01). The multivariate Cox regression analysis showed that Transgelin expression level was one of the independent prognostic factors in tumor free survival after surgery. Conclusions The expression of Transgelin in hepatocellular carcinoma was significantly associated with recurrence in patients with HCC after hepatectomy, and this protein could be the biomarker of the prognosis in HCC surgery.
