AIM: Hydroxymethylglutaryl CoA (HMG-CoA) reductase inhibitors, such as simvastatin, have been shown to reduce atherosclerotic cardiovascular morbidity and mortality by mechanisms unrelated to its lipid-lowering effect. Several studies have shown that simvastatin induces apoptosis in a varieties of cell lines including vascular smooth muscle cells (VSMC). The aim of this study was to investigate the signal pathways involved in apoptosis induced by simvastatin. METHODS: Cultured VSMC were treated with simvastatin. Calpain activity was determined by measuring Ca 2+ ionophore-specific calpain substrate (suc-LLVY-AMC), caspase-3 activation was detected by Western blot, and apoptotic changes were distinguished by annexin Ⅴ binding and DNA laddering. RESULTS: After incubated with 30 ?mol/L simvastatin for 8 h, calpain activity had a marked increase ( P

Objective To evaluate the safety and feasibility of hepatic resection for huge primary liver carcinoma (PLC). Methods 216 cases of huge PLCs(mean diameter of 14.2cm) were resected. The hepatectomies were performed under intermittent occlusion of hepatic inflow. Results All 216 cases were successfully resected. The mean time of occlusion of hepatic inflow was 19min, the mean blood loss was 743 ml. No serious complications occurred, and only seven patients died of hepatic failure and upper gastrointestinal haemorrhage postoperatively in this series. Conclusions Although resection of huge PLC is quite difficult, but if suitable surgical techique and perioperative management are adopted ,it is safe and feasible .

Objective: To study the alleviation of curcumin analog WZ35 on type 1 diabetic nephropathy (DN). Methods: Mice were treated with a single ip injection of streptozocin (STZ) to induce type 1 diabetes, while the control animals received the same volume of citrate buffer. The curcumin and its analog WZ35 (20 mg/kg) were ig administration for 9 weeks after the diabete obtained. The body weight and blood glucose were monitored every 7 d. Biochemistry analyzer was used to analyze the creatinine (Cr) and urea nitrogen (BUN) levels in serum. The histopathology of kidney tissue was detected by HE staining. RT-qPCR assay was used to evaluate the gene levels of inflammatory cytokines and chemokines. CD68 staining was used to evaluate the macrophages infiltration in kidney tissue. Results: Compared with negative control, the mice in diabetic group showed the reduced body weight, increased blood glucose, high Cr and BUN levels in serum, renal pathological damage, and increased inflammatory gene, and macrophages infiltration in kidney. While the administration with curcumin and its analog WZ35 could obviously attenuate the DN through inhibiting Cr and BUN in serum while had no effect on the body weight and blood glucose. Compared with curcumin, WZ35 could inhibit the gene expression of inflammatory cytokines and chemokines as well as infiltration of macrophages. Conclusion: The curcumin analog could attenuate DN through inhibiting inflammatory response.

BACKGROUND: Paraquat (PQ) is a world-wide used herbicide and also a type of common poison for suicide and accidental poisoning. Numerous studies have proved that the concentration of serum PQ plays an important role in prognosis. Spectrophotometry, including common spectrophotometry and second-derivative spectrophotometry, is commonly used for PQ detection in primary hospitals. So far, lack of systematic research on the reliability of the method and the correlation between clinical features of patients with PQ poisoning and the test results has restricted the clinical use of spectrophotometry. This study aimed to evaluate the reliability and value of spectrophotometry in detecting the concentration of serum PQ. METHODS: The wavelengths for detecting the concentration of serum PQ by common and second-derivative spectrophotometry were determined. Second-derivative spectrophotometry was applied to detect the concentration of serum PQ. The linear range and precision for detection of PQ concentration by this method were confirmed. The concentration of serum PQ shown by second-derivative spectrophotometry and HPLC were compared in 8 patients with PQ poisoning. Altogether 21 patients with acute poisoning 4 hours after PQ ingestion treated in the period of October 2008 to September 2010 were retrospectively reviewed. The patients were divided into higher and lower than 1.8 μg/mL groups based on their concentrations of serum PQ measured by second-derivative spectrophotometry on admission. The severity of clinical manifestations between the two groups were analyzed with Student's t test or Fisher's exact test. RESULTS: The absorption peak of 257 nm could not be found when common spectrophotometry was used to detect the PQ concentration in serum. The calibration curve in the 0.4–8.0 μg/mL range for PQ concentration shown by second-derivative spectrophotometry obeyed Beer's law with r=0.996. The average recovery rates of PQ were within a range of 95.0％ to 99.5％, relative standard deviation (RSD) was within 1.35％ to 5.41％ (n=6), and the lower detection limit was 0.05 μg/mL. The PQ concentrations in serum of 8 patients with PQ poisoning shown by second-derivative spectrophotometry were consistent with the quantitative determinations by HPLC (r=0.995, P<0.0001). The survival rate was 22.2％ in patients whose PQ concentration in serum was more than 1.8 μg/mL, and the incidences of acidosis, oliguria and pneumomediastinum in these patients were 55.6％, 55.6％and 77.8％, respectively. These clinical manifestations were different significantly from those of the patients whose PQ concentration in serum was less than 1.8 μg/mL (P<0.05). CONCLUSIONS: For common spectrophotometry, the wavelength at 257 nm was not suitable for detecting serum PQ as no absorbance was shown. Second-derivative spectrophotometry was reliable for detecting serum paraquat concentration. Serum PQ concentration detected by second-derivative spectrophotometry could be used to predict the severity of clinical manifestations of patients with PQ poisoning, and PQ content higher than 1.8 μg/mL 4 hours after ingestion could be an important predictive factor for poor prognosis.

Objective To explore genes expression of adiponectin receptors during differentiation of SW872 preadipocytes. Met-(hods) SW872 preadipocytes were cultured in vitro and induced to differentiate by 0.6 mmol/L oleic acid. During the progress of diffe-(rentiation), the morphological changes of SW872 cells were observed and the differentiation rate was assayed by oil-red O staining. Adiponectin receptors mRNA was measured by reverse transcription-polymerase chain reaction during differentiation of SW872 preadipocytes. Results 1.After stimulated by 0.6 mmol/L oleic acid for 72 hours, almost all SW872 cells were differentiated,and there were lots of fat droplets in the cells.2.There were adiponectin receptors genes expressions in SW872 preadipocytes.After 72 hours,and the levels of adiponectin receptor(AdipoR) 1 mRNA and AdipoR 2 mRNA were markedly increased up to 2.54 and 4.09 times,respectively. Conclusion There are AdipoR1 and AdipoR2 genes expressions in fat cells and the expressions are differentiation-dependent.

Objective To compare the effectiveness of medicated γintrauterine device (IUD) and medicated genefix IUD inserted immediately after abortion. Methods A multicenter clinical trail was performed for the study from Mar. 2012 to Jan. 2013. Totally 840 women who volunteered to participate were randomly allocated to γ-group (medicated γ IUD) or genefix-group (medicated genefix IUD) immediately after abortion. While 464 abortion women who had not used IUD or steroids contraceptive methods were chosen as control group. The effectiveness of the IUD were followed up for 1 year. All women were required to record the number of vaginal bleeding days and blood volume of vaginal bleeding within 3 months after abortion. Results At the 12th month, the expulsion was the most common reason for termination. The expulsion rates of genefix-group and γ-group were 2.48/100 women years and 3.12/100 women years, respectively (P>0.05). For the expulsion reasons, IUD moving down could account for more than seventy percent. The removal rate for IUD usage of two IUD groups were almost equal (3.91/100 women years verus 4.35/100 women years), the differences were not statistically significant (P>0.05). At the 90th day after abortion, comparing with control group, the bleeding and (or) spotting days of genefix-group and γ-group extended by 3.9 and 2.6 days respectively, the differences had statistical significance between the three groups (P<0.05). Among the bleeding and (or) spotting days, spotting days prolonged significantly. At the 12th month, spotting days of genefix-group andγ-group were (9.2±5.9) days and (8.5±4.6) days respectively, more than (5.2 ± 4.0) days of control group. The differences had statistical significance between IUD with control group (P<0.05), and had not between the two kinds of IUD (P>0.05). Conclusion The insertion of medicated genefix IUD and medicated γ IUD immediately after abortion is safe, feasible, has slight side effects and could be effective contraception.

Objective To observe the clinical manifestation and the mode of RET proto-oncogene mutation in a pedigree of mutiple endocrine neoplasia type 2A (MEN2A). Methods Genomic DNA was extracted from the peripheral blood lymphocytes in 18 family members including 3 patients, then PCR was performed to amplify seven exons of the RET proto-oncogene, i. e. exon 8,10,11,13-16. The PCR products were directly sequenced to identify the RET mutation and then sequenced after subcloning to identify their heterozygosity. Results The male proband suffered from pheochromocytoma and medullary thyroid carcinoma since the age of 30; while his sibling sister was ill with pheochromocytoma, and his brother with medullary thyroid carcinoma. A novel heterozygous mutation, 1893-1895delCGA, was detected in exon 11 of the RET proto-oncogene in the 3 patients and the other 2 family members. Conclusion A novel heterozygous mutation of RET proto-oncogene, 1893-1895delCGA, seems to be the disease-causing mutation in the studied MEN2A family.

Objective To observe and compare the association of serum levels of of complement component 3(C3)and high-sensitive C-reactive protein(hs-CRP)with insulin resistance in non-diabetic subjects. Methods 587non-diabetic Chinese were recruited. Weight, height, blood pressure, waist circumference, fasting plasma glucose,fasting serum insulin, blood lipids, C3 and hs-CRP were measured. HOMA index(HOMA2-IR)was calculated.Insulin resistance was defined as the upper quartile of HOMA2-IR. Results C3 and hs-CRP were significantly higher in subjects with insulin resistance compared with subjects without insulin resistance. After controlling for age, gender,body mass index, and waist circumference, C3 was positively and significantly correlated with HOMA2-IR(r = 0.19,P＜0.01). As C3 increased, subjects were 3.78(OR= 3.78, P＜0.05)times more likely to suffer from insulin resistance, after adjustment for age, gender, systolic blood pressure, diastolic blood pressure, total cholesterol,triglycerides,high-density lipoprotein cholesterol, and waist circumference. However, hs-CRP was not significantly correlated with insulin resistance. Conclusions Serum complement component 3 has a more marked association with insulin resistance than hs-CRP in non-diabetic Chinese.
