OBJECTIVETo evaluate the efficacy and safety of bicyclol for chronic hepatitis B.

METHODThe authors searched CBMDisk, CJFD (2000-2006), CJD-CD, PubMed (1966-2006) for randomized controlled trials (RCT) comparing bicyclol versus non-antiviral interventions, interferon alpha (IFN-a) and lamivudine for treatment of chronic hepatitis B. Two reviewers performed data extraction and quality assessment independently and discussed when there was different opinion. We analyzed the data with RevMan 4.2 software supplied by Cochrane Collabration.

RESULTSFourteen RCTs involving 1782 patients were included. ALT recovery rate of bicyclol group was 69.3 percent while that of the control group was 59.0 percent, the difference was statistical significant [RR 1.24, 95 percent CI (1.01, 1.52), P=0.04]. Loss of HBeAg in the bicyclol group (22.1 percent) was higher than that of the control group (13.5 percent) [RR 1.65, 95 percent CI (1.32, 2.06), P<0.00001]. No serious adverse events were reported.

CONCLUSIONBicyclol might be beneficial to recovery of liver function and loss of serum HBV marker. However, more high quality clinical trials are needed for confirmation.

Using the latency of paw withdrawal (PWL) from a noxious thermal stimulus as a measure of hyperalgesia, the effects of i.p. injection of meptazinol and its isomers, 112824 and 112825, on carrageenan-induced thermal hyperalgesia were studied in awaked carrageenan-inflamed rats. Peripheral inflammation was induced by intraplantar (i.pl.) injection of carrageenan (2 mg/100 microl) into one hindpaw in rats. Carrageenan produced marked inflammation (edema and erythema) and thermal hyperalgesia in the injected paws, which peaked at 3 h after injection and showed little change in magnitude for another 3 h. Injection of 0.1 mg/kg meptazinol (i.p.) at 3 h after carrageenan had no effect on the PWLs of either inflamed or non-inflamed hindpaw during the next 100 min (P>0.05, n=8). At the dosage of 1 and 10 mg/kg, meptazinol produced marked anti-nociception and anti-hyperalgesia in non-inflamed and inflamed hindpaw, respectively (P<0.05, n=8-11). The prolonging effect of meptazinol on PWL in inflamed hindpaw was more potent than that in non-inflamed hindpaw. Pre-administration of 1.5 mg/kg naloxone significantly antagonized meptazinol-induced anti-nociception and anti-hyperalgesia. Intraperitoneal injection of an isomer of meptazinol, 112825 (1.5 mg/kg), but not 112824 (1 mg/kg), markedly increased the PWL of the non-inflamed hindpaw. Nevertheless, both the isomers produced similar anti-hyperalgesic effect to that of meptazinol (P<0.05, n=8), which was completely reversed by naloxone (1.5 mg/mg). The results suggest that meptazinol and its isomers have anti-nociceptive and anti-hyperalgesic properties with the former more potent. The effects are mainly mediated by mu opioid receptors. This study provides an important clue for extending clinical utilization of meptazinol and its isomers.

AIMTo study the relativity of the renocortical lipid peroxidation with renal tubules structure damage in renal injury induced by cisplatin in rats.

METHODSFemale Wistar rats were randomly divided into NS group, CDDP(I) group, CDDP(II) group and CDDP(III) group. All rats were injected via the tail vein with NS or cisplatin and NS qd in five days. The changes in content of Scr, BUN and MDA, the activity of SOD and GSH-Px of the renal cortex were measured. Alkaline phosphatase of renal tubular epithelia was stained by histochemistry and the slices of renal cortex were observed.

RESULTSThe contents of Scr and BUN of CDDP groups were significantly higher than those of NS group (P < 0.01). The content of renocortical MDA was significantly higher than that of NS group (P < 0.05). The activities of renoconical SOD and GSH-Px were lower than those of NS group (P < 0.05). The content of MDA, activities of renocortical SOD and GSH-Px with the content of Scr and BUN were significantly correlative. Alkaline phosphatase of renal tubular epithelia cells was losed largely and renal tubular epithelia cells were denaturative and necrotic partly in sections.

CONCLUSIONThe damage of renal cortex was correlative with its lipid peroxidation. The injury of renal cortex became heavier with cisplatin dose increased.

OBJECTIVETo investigate the clinical features and genetic diagnostic method of cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL).

METHODSA systematic study on the clinical manifestations, neuroimaging characteristics, therapeutic measures and molecular genetics was performed. An investigation on the onset and hereditary pattern of the family was also done.

RESULTSThe main clinical features including poor memory and history of stroke were found. And no risk factors of hypertension and arteriosclerosis were found. A positive family history was confirmed. Neuroimaging examination showed multiinfarct lesions and leukoencephalopathy. All these features are in conformity with those of CADASIL. A mutation in the third and fourth exon of the NOTCH3 gene was identified in the 10 cases of 4 generations. The clinical or subclinical onset in the 10 cases was consistent with classical autosomal dominant inheritance.

CONCLUSIONThe clinical and molecular genetic features of the family accord with CADASIL.

OBJECTIVETo study the association of beta-fibrinogen(Fg) gene -148 C/T and 448 G/A polymorphisms, plasma Fg concentration, molecular reactivity and the type of cerebral infarction.

METHODSGene polymorphisms were analyzed by polymerase chain reaction-restriction fragment length polymorphism. The plasma Fg concentration and the molecular reactivity were also determined.

RESULTSThe Fg concentration in MCI patients with T -148 allele was higher than that in PCI patients and controls. The MCI patients with A448 allele had higher Fg concentration, FMPV and FMPV/Amax when compared with controls, and had higher FMPV/Amax when compared with PCI patients.

CONCLUSIONFgB beta -148 and 448 mutational genotypes have impact on Fg concentrationì and therefore increase the risk of MCI.

Objective To detect the expression of matrix metallproteinases(MMPs) in aortic valve of children who suffered from rheumatic heart disease(RHD) and to explore the pathological role of MMPs in children′s rheumatic aortic valve disease.Methods RHD group composed of 18 aortic valves from children suffered from RHD.Controls were 8 children who were died accidentally without cardiovascular system diseases.Hematoxylin and eosin stain observing the histological characteristic of the 2 groups.Immunohistochemistry was used to detect expression of MMP2 and MMP9 on aortic valves in 2 groups.Results Hematoxylin and eosin stain showed:in RHD the valves′ structure were destroyed along with fibrous tissue proliferation,mucinous degeneration,collagen and fiber hyalinization,blood vessel and blood capillary proliferation,lymphocyte,plasmocyte,monocyte infiltration.Immunohistochemistry showed that MMP2 and MMP9 expression were significantly higher than those in the aortic of RHD(68.85?13.08,64.35?9.59) compared with control group(107.31?23.39,116.28?6.99)(t=3.92,10.18 all P

Objective To analyze the factors correlated with perinatal death so as to provide the basis for reducing the perinatal mortality.Methods A respective study was conducted with analysis of perinatal mortality monitoring data,birth defects data and the health status report of non-registered pregnant women from 2012 to 2016 in Taizhou. We compared the differences in the indexes of perinatal mortality,birth defects rate and the proportion of elderly pregnant women in different years,domicile place and regions.Results The perinatal mortality rate was 6.80‰,decreasing annually from 2012 to 2016 (P<0.01). The average perinatal mortality rate of floating population was 9.28‰,which is higher than the 5.64‰ rate of local population (P<0.01). The proportion of elderly pregnant women was 10.30%,showing an upward trend (P<0.01) and the perinatal mortality of elderly pregnant women was 10.60‰,significantly higher than the total mortality (P<0.01). The leading cause of perinatal death was birth defect and the defect rate of perinatal birth was 35.86‰,showing an upward trend (P<0.01) while the average mortality rate of birth defects was decreasing (P<0.01). There were statistically significant differences(P<0.01) in perinatal mortality,birth defects,sex ratio and proportion of elderly pregnant women in different regions of Taizhou. Compared with the perinatal in local population,mother age,education background,maternal times and register time of pregnant women of the perinatal in floating population was significantly different (P<0.01). Conclusion The perinatal mortality in Taizhou declined year by year. Elderly pregnant age,birth defects,and floating population are the main positive factors of perinatal mortality.
