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 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.

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.

We have reformed our patterns and methods of graduation examination of the medical majors. That is the multi-stage comprehensive graduation examination of the clinical interns, which consists of 70% close written test of clinical theories,20% practical test of clinical skills and also oral test of related theories, and 10% writing of the medical documents. It has proved that these measures have improved the interns' attitude toward practice, aroused their initiative and positivity, and led the practitioners to attach more importance to the combination of clinical practice and theories, thus leading to better clinical education.

This systematic review was aimed to evaluation the effectiveness and safety of supplementingqi and activating blood circulation prescriptions in the treatment of cerebral ischemic stroke. Dtabases both at home and abroad were electronically searched for randomized controlled trials (RCTs) on supplementingqi and activating blood circulation prescriptions in the treatment of cerebral ischemic stroke. And meta-analyses were performed using RevMan 5.0 software. The results showed that 27 studies were included, which contained 2 908 cases. There were 1 490 cases in the treatment group, and 1 418 cases in the control group. The results of meta-analyses indicated that supplementingqi and activating blood circulation prescriptions combined with routine treatment of modern medicine had significant differences in the effective rate for cerebral ischemic stroke compared with the single using of routine treatment of modern medicine with significant difference (OR = 5.39, 95%CI (4.03, 7.22),P < 0.000 01). The treatment of supplementingqi and activating blood circulation prescriptions combined with routine treatment of modern medicine had better treatment effect on neurological function defects for cerebral ischemic stroke compared with the single using of routine treatment of modern medicine with significant difference (WMD = -2.99, 95%CI (-3.26, -2.72),P < 0.000 01). In addition, the treatment of supplementingqi and activating blood circulation prescriptions combined with routine treatment of modern medicine had better treatment effect on improving the activity of daily living (WMD = 9.65, 95%CI (8.36, 10.93),P < 0.000 01). Adverse reaction and event was mild in 2 included research reports. It was concluded that the treatment of supplementingqi and activating blood circulation prescription or it combined with routine treatment in modern medicine was quite effective in the treatment of cerebral ischemic stroke by the existed limited evidences. It can also improve the nerve dysfunction and the ability of daily living. Due to the limited quantity of the included studies and the evidence with limited strength, further high-quality RCTs were needed to verify the forementioned conclusion.

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.

AIM: To explore the relationship between dynamic changes of population spike (PS) and morphologic alterations in hippocampal CA1 region and morphology after transient ischemia/reperfusion and the improving effects of Chinese herbs 9602. METHODS: Changes of evoking population spike ware investigated by electrical stimulating Schaffer collateral in CA1 region of hippocampal slice after ischemia/reperfusion in vivo . Apoptosis and morphologic alterations at different time points after cerebral ischemia/reperfusion were detected by using TUNEL and Nissl staining. RESULTS: The threshold voltage of CA1 region in evoking population spike increased markedly as compared with sham control. The enhancement of wave amplitude was reduced significantly after tetanic stimulation. The duration of enhancement in amplitude decreased with the passage of reperfusion. Above all were observed from 8 h after ischemia/reperfusion. They became remarkable and got to its top at 7 day after ischemia/reperfusion treatment. TUNEL positive cells were observed in hippocampal CA1 region at 8 h, got to the top at 24 h and then gradually reduced after ischemia/reperfusion. A lot of abnormal cells in CA1 region was found, and the number of pyramidal cell reduced progressively by Nissl staining after ischemia/reperfusion. Chinese herbs 9602 reduced the threshold voltage of CA1 region in evoking population spike remarkably, enhanced the wave amplitude and prolonged the duration of PS enhancement; decreased the number of TUNEL positive cell, prevented the reduction of pyramidal cell in CA1 region. CONCLUSIONS: The excitability and reactivity were decreased and there was a gradual functional disturbance of synaptic transmission in CA1 pyramidal cell and most notable changes happened at 7 d ischemia/reperfusion, suggesting that was partly due to delayed neuronal death induced by ischemia/reperfusion. Apoptosis plays an important role in the functional deficiency of CA1 region of hippocampus induced by cerebral ischemia/reperfusion. The effects of 9602 on ameliorating the excitability and reactivity of CA1 pyramidal cells relate to inhibiting apoptosis, attanuating delayed neuron death induced by ischemia/reperfusion.
