Objective To investigate the effect of stigma maydis aqueous extract on glucolipid metabolism and oxidative stress in type 2 diabetic rats.Methods Male Sprague-Dawley rats were randomly divided into normal control group,model control group,positive control group(Metformin) and stigma maydis aqueous extract low,middle,high dose group.Type 2 diabetic rats model was induced by high-fat and high-sugar dietary feeds and streptozotocin(STZ) in all groups except the normal control group.After treatment of 8 weeks,automatic biochemistry instrument was applied to detecting the levels of fast blood glucose(FBG),triglyceride(TG),total cholesterol(TC) and low density lipoprotein cholesterol(LDL-C) in serum.The levels of free fat acid(FFA),malonaldehyde(MDA) and superoxide dismutase(SOD) in serum were assayed by uv-vis spectrophotometer.Results Compared with model control group,after stigma maydis aqueous extract treatment,middle and high dose groups remarkably lowered the levels of FBG,FFA,TG and TC in dose-dependent manner(P

Objective: To study the role of simian virus 40 large T antigen(SV40LTag) and telomeras in the proliferation of endothelial cells in hemangioma. Methods: The expression of SV40LTag was examined in 100 cases of hemangioma with immunohistochemistry, telomerase activity and telomeric length were measured by RT-PCR based telomeric repeat amplification protocol(TRAP) assay, telomeric restriction fragment (TRF) analysis and chemiluminescence in situ hybridization in 50 cases of hemangioma and 10 of squamous cell carcinoma. A sample of embryonic kidney endothelia was used as the contrdol. Results: SV40LTag expression was observed in 45 out off the 100 cases of hemangioma. Telomerase expression was found in 27 out off the 50 cases of hemangioma and all the 10 of squamous cell carcinoma. The telomeric length in hemangioma varied from 6.8 to 13.2 kb, 10.5-13.5 kb in squamous cell carcinoma and 12.4 kb in embryonic kidney endothelia. Conclusion: Transformation of endothelia by simian virus 40 may contribute to the occurring of hemangioma, telomerase may play a role in the proliferation of the endothelial cells in hemangioma.

Objective: To determine the effects of intravenous anesthetics (fentanyl,midazolam and propofol )on inflammatory responses. Method: We employed carrageenan-sensitized endotoxemic rabbit model. Thirty-two New Zealand rabbits were randomly assigned to one of four groups,control group(no anesthetic was used), fentanyl group, midazolam group and propofol group. Different anesthetics were used intravenously for anesthesia induction and maintenance according to the group classification. Meanwhile, all animals were mechanically ventilated, then, 2?g?kg~(-1) lipopolysaccharide(LPS) were injected for endotoxin challenge. Result:In all groups, serum tumor necrosis factor (TNF)activity began to increase at 30 min,reached its maximal level at 60 min,and tended to decrease at 120 min after (LPS) challenge,and the significant increase of TNF activity was associated with development of hypotension. Meanwhile,serum phospholipase A_2(PLA_2)activity began to increase at 60 min and persisted in going up within 2h. Those animals,with continuous infusion of these three different anesthetics and mechanical ventilation,had much lower peak level of TNF and higher mean arterial pressure (MAP)than control levels, but their changes of serum PLA_2 activity had no significant difference from control level. Conclusion: With mechanical ventilation, intravenous infusion of these anesthetics can reduce LPS induced injury in the acute phase of endotoxemia, probably by the inhibition of TNF production.

Two cases of chronic invasive fungal rhinosinusitis were reported. One patient healed while another died with suspicious residual fungal infection. The clinical symptoms of infratemporal fungal infection include maxillofacial pain, with or without fever. Acute or chronic inflammation of soft tissue could be revealed pathologically. Proof of pathogen may not be found in histopathological slice while serological detection may reveal positive evidence. Surgical resection, good drainage and postoperative antifungal therapy could cure or promptly relieve the symptoms of the disease.

Objective:To compare the hemodynamic responses to orotracheal intubation between TruviewTM EVO2 optic laryngoscope and Macintosh direct laryngoscope.Methods: Eighty adult patients(ASA physical status Ⅰ-Ⅱ,aged 18-65 years) scheduled for elective surgery under general anesthesia requiring orotracheal intubation were randomly divided into 2 groups(n=40 each):T group and M group.After standard intravenous anesthetic induction,orotracheal intubation was performed with TruviewTM EVO2 optic laryngoscope or Macintosh direct laryngoscope.Non-invasive heart rate(HR),systolic blood pressure(SBP),diastolic blood pressure(DBP),mean arterial pressure(MAP) and SpO2 were recorded before(T0) and after anesthetic induction(T1),at intubation(T2),1 minutes(T3),3 minutes(T4) and 5 minute after intubation(T5).The laryngeal exposure period and intubation period were also recorded.Statistical analysis was performed using the Statistical Package for Social Sciences(SPSS) Version 13.0.Results: Except for HR at intubation(T2),there was no significant difference in the hemodynamic data at any other time points between the two groups.There was no significant difference in the laryngeal exposure period between the two groups.The intubation time in the T group was significantly longer than that in the M group(P

Objective The purpose of the current study was to develop a real-time quantitative reverse transcription-PCR method for detection of human kallikrein gene 5(KLK5) mRNA expression,quantify the expression of KLK5 mRNA in malignant and benign breast tissues,and statistically analyze whether KLK5 expression levels correlate with clinicopathologic variables in the patients with breast cancer.Methods Paired breast tissue samples from cancerous and corresponding noncancerous tissues were obtained from 48 patients with breast cancer who underwent surgical resection.The relationship of KLK5 mRNA expression status with various clinicopathologic variables were quantitativly analyzed by real-time RT-PCR.Results KLK5 mRNA expression in cancerous tissues was decreased in 38 of 48(79%) breast cancer patients compared with normal counterparts.The mean expression level of KLK5 mRNA in cancerous tissues was significantly lower than that in noncancerous tissues(P0.05).Conclusion The results of this study indicated that KLK5 mRNA expression was significantly lower in cancerous tissues than that in noncancerous breast tissues,and low expression of KLK5 mRNA correlated with TMN stage,metastasis and ER status.

AIM: To study the protection of extract of Radix Atragali composite against acute hepatic injury. METHODS: Fed with the extract of Radix Atragali composite, m ice were injected with D-galactosamine intraperitoneally (800 mg/kg) and rats were i njected with carbon tetrachloride hypodermically (5 mL/kg) to induce acute hepat ic injury on the 8th day. ALT, AST and bilirubin in serum were examined. Patholo gical changes of liver tissue were observed. RESULTS: Compared with model group, activities of ALT and AST, c oncentrations of bilirubin were markedly decreased and pathological scores also showed that degeneration and necrosis of hepatic cell were lighter in the the ex tract of Radix Atragali composite treatment group. CONCLUSION: The extract of Radix Atragali composite attenuat es hepatic injury induced by D-galactosamine or carbon tetrachloride.
