Objective To explore the effects of rosiglitazone on the expression of TNF-? in visceral adipose tissue of insulin-resistant rats induced by high-glucose diet. Methods Sprague-Dawley (SD) rats were fed with high-glucose diet for 6 months to reproduce the non-obesity insulin-resistant rat model (abbreviated as IR rats). The model rats were then randomized into insulin resistan (IR) group and rosiglitazone (ROS) group (10 each). Ten rats fed with normal diet were enrolled as controls (CN group). Rats in ROS group were administered with 10?mol/(kg?d) of rosiglitazone for 6 weeks from the 7th week of experiment,and those in CN and IR groups were administered with same amount of distilled water. At the 6th and 12th week,the systolic pressure,body weight,and biochemical parameters (fasting and 2-hour post-glucose load plasma glucose,insulin,free fatty acid,triglyceride,high density lipoprotein cholesterol) were measured,and insulin resistance index (HOMA-IR) was calculated. At the end of the 12th week,the visceral adipose tissue was collected to calculate the ratio of visceral fat to body weight (VF/BW),and to determine the protein and mRNA expressions of tumor necrosis factor-? (TNF-?) with inmmunohistochemical assay and RT-PCR. Results As compared with CN group,the systolic pressure,HOMA-IR,plasma insulin,triglyceride and free fatty acid increased,whereas high density lipoprotein cholesterol decreased (P0.05). Inmmunohistochemical examination showed positive expression of TNF-? in intercellular substance,but not in visceral adipocytes. The expressions of TNF-? protein and mRNA in visceral adipose tissue were dramatically higher in IR group than in CN and ROS groups (P0.05). Conclusion Rosiglitazone may significantly abate insulin resistance,reduce the abnormality of plasma lipid and blood pressure,and inhibit the over expression of TNF-? in visceral adipose tissue in the non-obesity insulin-resistant rats induced by high-glucose diet.

Objective To analyze the distribution of human papillomavirus (HPV) genotype in the diseases associated with HPV infection and explore the role of HPV genotype in these diseases. Methods Retrospective analysis was carried out to compare HPV genotypes of 353 outpatients suffering the diseases associated with HPV infection including cervical caner,cervical intraepithelial neoplasia (CIN),genital duc condyloma,and subclinical cervical human papillomavirus infection (SPI) in our department from January to October 2008. HybriMax were used to detect HPV genotype. The distribution data of HPV genotype were statistically analyzed. Results Totally 176 HPV positive females were found with a positive rate of 49.86%. HPV positive rate in cervical cancer was 100%,and all of them were high risk HPV. The positive rate was increased with the severity of CIN,and the higher histological-grade was,the higher HPV positive rate was (P

Objective: To investigate the potential role of me latonin in the adrenal cortex of human embryo. Methods:Specifi c melatonin receptors was localized and characterized in the adrenal cortex of h u man embryo by means of immunohistochemistry. Results: mt1 （Me l1a）and MT2 （Mel1b）subtype of melatonin receptors was principally localize d to cytoplasm in zona glomerulosa， fasciculata and reticularis. Conclu sion: It is possible that mt1 and MT2 subtype of melatonin receptors co-exist in the adrenal cortex of human embryo.

Objective To investigate the event-based prospective memory(EBPM)and time-based prospective memory(TBPM)in schizophrenia patients with concomitant metabolism syndrome,and to provide theory basis for early intervention and treatment.Methods According to inclusion standard,50 schizophrenia patients with concomitant metabolism syndrome and 50 schizophrenia patients without metabolism syndrome matched in age,gender and education were assessed with a neuropsychological battery of tests including EB-PM and TBPM tasks.Results In the EBPM task,there was significant difference between schizophrenia pa-tients with and without metabolism syndrome (3.46±0.91 vs 3.86±0.81, t=-2.326, P=0.022).A statistically significant difference in TBPM was observed between schizophrenia patients with and without metabolism syn-drome (3.02±1.12 vs 3.78±0.89, t=-3.770, P=0.000).Conclusion The schizophrenia patients with me-tabolism syndrome have severer prospective memory impairment than those without metabolism syndrome.

OBJECTIVETo investigate the effect of four traditional Chinese medicines distributed along lung meridian, namely Ephedrae Hebra, Zingiberis Rhizoma, Scutellariae Radix and Mori Cortex, on TLR2 and NF-κB expressions in mice with lung heat syndrome, in order to study the intervention effect of the four traditional Chinese medicines (TCMs) on the lung heat syndrome.

METHODOne hundred KM mice were randomly divided into the normal control group, the model group, the Ephedrae Hebra group, the Zingiberis Rhizoma group, the Scutellariae Radix group and the Mori Cortex group (20, 10 g x kg(-1)), nasally dripped with streptococcus pneumoniae to establish the mouse lung heat syndrome model, and then administered with different TCMs. The expressions of TLR2, NF-κB p65 proteins in lung tissues were analyzed by the immunohistochemical method. The expressions of TLR2, NF-κB p65 mRNA were measured by real time PCR.

RESULTCompared with the normal control group, the expressions of TLR2 and NF-κB p65 proteins in lung tissues in the model group were higher (P < 0.01), and the expressions of TLR2 and NF-κB p65 mRNA in lung tissues were up-regulated (P < 0.01 or P < 0.05). Compared with the model group, Ephedrae Hebra high and low dose groups, the Zingiberis Rhizoma low dose group and the Scutellariae Radix high dose group showed decreased expression of TLR2 protein (P < 0.05 or P < 0.01); Ephedrae Hebra high and low dose groups, the Zingiberis Rhizoma low dose group, Scutellariae Radix high and low dose groups and Mori Cortex high and low dose groups showed reduced expression of NF-κB p65 protein (P < 0.05 or P < 0.01). Ephedrae Hebra high and low dose groups, Zingiberis Rhizoma high and low dose groups, Scutellariae Radix high dose group and Mori Cortex high dose group showed down-regulated expression of TLR2 mRNA (P < 0.01 or P < 0.05).

CONCLUSIONEphedrae Hebra, Zingiberis Rhizoma, Scutellariae Radix and Mori Cortex can induce the TLR2/NF-κB inflammatory signal pathways by down-regulating the expressions of TLR2 and NF-κB p65 in protein and mRNA, so as to alleviate the lung tissue injury in mice with lung heat syndrome.

[ABSTRACT]OBJECTIVETo investigate the diagnosis, treatment method, key points of operation, and postoperative complications of high-risk esophageal foreign body.METHODSA retrospective analysis of 41 cases of high-risk esophageal foreign body from January 1996 to December 2014. After adequate preparation, the foreign body was removed via esophageal endoscope under general anesthesia.RESULTSThe foreign bodies in 41 patients were removed via esophageal endoscope once or twice. Two cases suffered postoperative subcutaneous emphysema, that may be a result of a small perforation in esophagus. Emphysema was disappeared by fast, rehydration and anti-infection for 6 to 8 days, and other serious complications did not occur.CONCLUSIONMost high-risk esophageal foreign bodies can be removed through rigid esophagoscopy. Some of the foreign bodies of the patients were difficult to remove, some patients were presented with mediastinal emphysema and pneumothorax due to esophageal perforation, and some foreign body stuck in oesophagus so long to cause esophageal mucosa ulcer. In these conditions, foreign bodies should be removed by lateral neck incision or thoracotomy.
