Objective: To explore the impact of insulin resistance (IR) and adiponectin (APN) lacking on myocardial remodeling in experimental mice. Methods:16 normal C57 mice were divided into 2 groups: Control group and IR group; in addition, 16 APN gene knockout(APNKO) mice were divided into another 2 groups: APNKO group and APNKO+IR group.n=8 in each group. The mice in Control group and APNKO group were fed with normal diet, in IR group and APNKO+IR group were fed with high fat diet to create the IR model. All animals were treated for 12 weeks. Blood levels of total cholesterol(TC), triglycerides(TG),fasting plasma glucose(FPG) and fasting insulin(FINS) were examined; heart weight and left ventricular weight were measured; left ventricular myocardial morphological changes and the degree of ifbrosis were assessed by HE staining and Masson staining; protein expressions of myocardial matrix metalloproteinase-9 (MMP-9) and APN were detected by immunehistochemistry and Western blot analysis. Results: Compared with Control group, IR group, APNKO group and APNKO+IR group showed elevated blood levels of TC, TG, FPG and FINS; increased heart weight and left ventricular weight, allP<0.05; IR group, APNKO group and APNKO+IR group presented more myocardial hypertrophy, decreased protein expression of APN and increased protein expression of MMP-9, allP<0.05.Conclusion: IR and APN lacking could incur myocardial remodeling in experimental mice and they had synergistically facilitated effect.

Objective To study the anatomy basis and biomechanical stability of euthyphoria reduction and percutaneous cannulated screw fixation for sacroiliac dislocation,and to evaluate the primary clinical efficacy of this method.Methods The distances from the anterior branches of the nerve roots at L4,and L5 and obturator nerve on the superior border of sacral ala to the sacroiliac joint were measured on 12 adult cadavers (24 sides) fixed and preserved by formalin.Models of sacroiliac dislocation were made on six pelvic specimens of fresh cadavers.A comparison of stability was made on the six models between the fixation studied here and the traditional fixations by posterior percutaneous sacroiliac screws and by anterior sacroiliac joint plates.At the same time,17 patients with type C Tile fracture were treated with our method.The clinical efficacy was analyzed for the 17 patients.Results The distances from the anterior branches of the nerve roots at L4,and L5 and obturator nerve on the superior border of sacral ala to the sacroiliac joint were 20.24?1.20mm,23.80?1.43mm,and 16.26?2.07 mm respectively. There was no statistically significant difference in stability between our method and the traditional fixation by posterior percutaneous sacroiliac screws,though ours seemed better.Follow-ups for the 17 cases averaged 2.2 years,re- vealing fine functional recovery in all according to Matta scoring.Conclusions Euthyphoria reduction and per- cutaneous cannulated screw fixation can lead to sufficient biomechanical stability for the sacroiliac joint and effec- tively avoid nervous injuries.In addition,our method is simple and clinically effective,It is recommendable for small and middle-sized hospitals.

Objective To explore the difference of gene expression profiling between normal basilar arteries and basilar arteries of cerebral vasospasm (CVS) after subarachnoid hemorrhage (SAH) in rabbits. Methods cDNA chip of normal basilar arteries and basilar arteries of CVS after SAH in rabbits were downloaded from GEO database. The chip was analyzed and screened by Bioconductor software, and function enrichment and pathway analysis of the differentially expressed genes were analyzed by Cytoscape software. Then 6 adult male Japanese rabbits were used, and randomly divided into normal control group (n=3) and SAH model group (n=3). Rabbit SAH models were established by cisterna secondary-blood-injection method. RNA data of normal basilar artery specimens on the 0 day and basilar artery specimens after SAH on the 5-day were used to validate the parts of differentially expressed genes by qRT-PCR. Results A total of 4356 differentially expressed genes were found in normal basilar arteries and basilar arteries of CVS after SAH in rabbits. Among them, 920 genes were considered to be significant with P-value<0.05, such as GRIK1, MYH13, ZNF45, SAA3, RLN1, MSR1 and others. Function enrichment analysis indicated that the differentially expressed genes were involved in regulation of Ca2+transmembrane transporter activity, negative regulation of ion transmembrane transport, regulation of potassium ion transport, positive regulation of JAK-STAT signaling cascades and other biological processes. Pathway analysis showed that calcium signaling pathway, cGMP-PKG signaling pathway, HIF-1 signaling pathway, PI3K-Akt signaling pathway and other signaling pathways maybe related with the differentially expressed genes. qRT-PCR verification showed that the expression of MSR1 in SAH model group was consistent with that of the chip result. Conclusion The gene expressions of basilar arteries of CVS after SAH in rabbits are significantly different, and MSR1 gene can be used as a potential target for studying the pathological mechanism of CVS.

Objective:To study the effect of OSAHS on adult nasal-cycle.Method:The nasal cycle of 20 healthy adults,18 patients of snoring and 22 patients of OSAHS were examined with acoustic rhinometry,which was performed every 30 minutes in 7 hours.Result:The ratio of nasal cycle in healthy adults was(19/20,95.0%), in snoring patients was(15/18,83.0%),in patients of OSAHS was(15/22,68.2%). The mean alteration amplitude of nasal cycle in healthy adults was significantly larger than that in patients with OSAHS (P<0.05).The distribution of the healthy adults and patients with OSAHS between the typical cycle categories was significantly different(P<0.05).Conclusion:The characteristics of nasal-cycle in of OSAHS patients were different with healthy adults,which maybe owing to change of physical function of nasal cavity.

Severe liver disease during pregnancy is uncommon in clinical practice. The most common cause of liver disease during pregnancy is liver dysfunction, with an overall prevalence rate of approximately 3%. Liver disease during pregnancy is classified into the liver diseases directly caused by pregnancy and those co-existing with pregnancy, i.e., pre-existing liver disease or occasional liver disease during pregnancy. A differential diagnosis of pre-existing and co-existing liver diseases may help to improve maternal and fetal outcome. During clinical diagnosis and selection of treatment and intervention measures, priority should be given to the potential impact on mother and fetus. This article introduces the latest research advances in the general information, pathogenesis, treatment, and pregnancy outcome of major liver diseases during pregnancy and elaborates on the risk of pregnancy and related coping measures for patients with pre-existing liver disease, so as to guide clinical diagnosis and treatment and patient management.

OBJECTIVETo compare curative effects of various surgical procedures of bile duct stones.

METHODSTwo thousand nine hundred and fifty-five patients with intrahepatic bile duct lithiasis who had undergone various surgical procedures were analysed with Meta-analysis. Some of these cases were reported in Chinese Medical Journals from January 1990 to March 2001 and others were from Tongji Hospital.

RESULTSThere was a significant difference between curative effects of non-hepatectomy and that of hepatectomy (chi(2) = 62.945, P < 0.01), and the outcomes of hepatectomy were much better than those of non-hepatectomy with OR(S) equalled to 0.303 (0.222 - 0.413). There was not a significant difference between curative effect of interposed jejunum and that of hepatectomy (95% CI of RR from 0.98 to 1.04). All the other operation, effects were worse than hepatectomy (upper limit of 95% CI of RR < 1).

CONCLUSIONSHepatectomy is the most ideal surgery for intrahepatic bile duct stones and operation methods should be diversified since good effect could also be obtained when other operations are performed on suitable cases.
