Objective To investigate the value of combined use of misoprostol and intravenous mixture of pethidine and droperidol during operative hysteroscopy. Methods A total of 168 cases scheduled for hysteroscopy were divided into 4 groups: Group Ⅰ (42 cases) was transvaginally given 0.4 mg misoprostol as monotherapy; Group Ⅱ (41 cases) was given 0.4 mg transvaginal misoprostol in combination with intravenous mixture of 50 mg pethidine and 2.5 mg droperidol; Group Ⅲ (43 cases) was given 0.4 mg transvaginal misoprostol combined with intravenous mixture of 100 mg pethidine and 5 mg droperidol; and Group Ⅳ (42 cases), intravenous mixture of 100 mg pethidine and 5 mg droperidol. The heart rate, breath rate, blood pressure, oxygen saturation, cervical responses, VAS scores and complications were assessed respectively. Results There were statistically significant differences regarding the degree of cervical dilatation, the operation time, and the used volume of cavity-distention media between the Group Ⅳ and the Group Ⅰ, Group Ⅱ, and Group Ⅲ, respectively (P0.05). Significant differences were observed in the analgetic effect in the 4 groups (?~2=86.325,P=0.000), among which the Group Ⅱ and Group Ⅲ were superior to the other two. All patients in the 4 groups represented a stable respiratory process and blood circulation, with no significant differences in the rate of adverse effects (?~2=1.649, P=0.648). Conclusions Transvaginal application of misoprostol offers a convincing effect for cervical dilatation. Combined use of misoprostol and mixture of 50 mg pethidine and 2.5 mg droperidol gives a satisfactory analgetic effect during operative hysteroscopy.

Hyperhomocysteinemia is an independent risk factor for arterial and venous obstructive vascular di-seases. Raised plasma homocysteine concentrations are caused by genetic and non-genetic factors. The pathogenic mechanism is not clear. It may be associated with endothelium dysfunction, abnormal lipid metabolism, hypertrophy of intima media, increased platelet aggregation and several clotting factors interfered, etc. The metabolism and pathogenic mechanism of homocysteine are reviewed in this article, which provides theoretical foundation for the treatement of hyperhomocysteinemia.

Objective The objective of this study was to observe effects of miR-409-5p on the proliferation and migration of HepG2 cells.Methods HepG2 cells were transfected with miR-409-5p mimics and verified by Real-Time quantitative PCR.After high expression of miR-409-5p,MTT and wound healing assays were used to detect the proliferation and migration ability of HepG2 cells.Results The cell viability of HepG2 cells transfected with miR-409-5p mimics was significantly decreased in comparison with the control group and showed a dose-and time-dependent manner(P<0.05).The migration ability of cells overexpressing miR-409-5p mimics was significantly lower than that in the NC group(P<0.05).There was significant difference between the two groups at treatments for 24 h and 48 h.Conclusion Up-regulated miR-409-5p can inhibit the proliferation and migration of HepG2 cells.

Objective To evaluate the effect of Jianpi Bushen Formula(Formula for Invigorating Spleen and Nourishing Kidney) combined with moxibustion on quality of life(QOL) and maturation degree of vaginal exfoliate cells(MDVEC) in premature ovarian failure(POF) patients.Methods Totally 55 POF patients were randomized into treatment group(33 cases,treated by Jianpi Bushen Formula with moxibustion) and control group(22 cases,treated by Premarine).Menopause-specified quality of life(MENQOL) was adopted to evaluate QOL of the patients.Maturation index(MI) and maturation value(MV) were applied to evaluate MDVEC.Results The scores of MENQOL of both groups were improved and the effect of the treatment group(except sexual life dimension) was superior to that of the control group(P

ObjectiveTo investigate the effect of immunoglobulin G (IgG) extravasated from blood circulation on the expression of toll-like receptor 4 (TLR4) induced by peripheral lipopolysaccharide (LPS) in rat brain. Methods The rats were divided into four groups in random, 5 rats in each. Group one received LPS 100μg/kg by intraperitoneal administration, normal saline was given by intravenous injection 6 hours later; group two was injected with adrenalin (AD) 15μg/kg intravenously; group three was treated with LPS intraperitoneally, AD was injected 6 hours later; group four was injected normal saline intravenously as control. For all groups, the animals were sacrificed 30 min after the last injection, and the brains were taken for investigation of the TLR4 expressions by immunofluorescence staining and RT-PCR. Result Immunofluorescence staining showed that IgG immunoreactive product was patch-like, distributed in the brain parenchyma in all the animals that received AD. In the LPS+normal saline group, IgG was found merely around the blood vessels. Meanwhile, in LPS+AD animals, TLR4 immunoreactive product coexisted with microglia marker Iba-1 within the IgG extravasated area. The double-labeled cells dispersed in the brain parenchyma and near to the cerebral vessels. In the LPS+saline group, TLR4 positive cells were endothelial-like. RT-PCR results indicated that the expression level of TLR4 in the LPS+AD group were significantly higher than that in the LPS+saline group or AD group or the saline control (P<0.01). Conclusion Extravasated circulating IgG may enhance the TLR4 expression in the rat brain induced by peripheral LPS.

Aim To study the in virto interaction o f Cefathiamidine in combination with Ciprofloxacin against clinical isolates of Staphylococcus aureus, Staphylococcus epidermidis, Enterococcus faecalis. Methods The activity of each drug alone was determined against all the isolates. Chequerborad synergy testing was then performed against all the isolat es. Results The percentage of the FIC index less than 0.5, from 0.5 t o 1,from 1 to 2,more than 2 was 53.3%～93.3%,6.7%～46.7%,0%,0% respectiv ely.

AIM and METHODS: To observe the dynamic changes in relative power of rats brain electrocorticogram(ECoG) and electrohippocampogram(EHG) after ischemia, we studied the changes of rat's ECoG and EHG after ischemia using the method of chronic implanting electrodes in cortex and hippocampus and the effects of Chinese herbs 9602 on them. RESULTS: The frontal ECoG relative power of all bands and total power decreased in 8 hours after ischemia, restored in 24 hours and decreased again after 72 hours. It decreased significantly as compared with that of sham-control 7 day postischemia. The occipital ? band at 72 hour, all bands and total power decreased 7 day after ischemia. As compared with sham-operated control, the ??? and total power of EHG decreased notably at 8, 24 and 72 h after ischemia. The changes were more markedly in 7 day after ischemia. Treated with 9602 and hydergine, the ischemic animals showed significant elevation of ECoG and EHG relative power in comparison with ischemic rats. CONCLUSION: The power of ECoG and EHG decreased after ischemia, it may be correlated with delayed neuronal death induced by ischemia. 9602 prevented the decreases in ECoG and EHG power obviously after ischemia,which probably related to the neuroprotective effects.
