ObjectiveTo explore the effects of different anesthesia approaches on hemorheology in patients with pregnancy-induced hypertension (PIH) during cesarean section.MethodsOne hundred and sixty-five patients with PIH were divided into epidural anesthesia (81 cases,control group) and combined spinal epidural anesthesia (84 cases,experiment group).The hemorheology and Apgar score were compared.Results The anesthesia and post-parturition,the levels of whole blood low shear viscosity,whole blood middle shear viscosity,whole blood high shear viscosity,erythrocyte aggregation index,plasma viscosity,fibrinogen were improved compared with those before anesthesia [experiment group:(6.3 ± 0.7 ),(6.6 ± 0.6)mPa·s vs.(8.1 ± 1.8) mPa·s,(3.8±0.6),(3.9±0.4) mPa·s vs.(5.2±0.9) mPa·s,(3.1 ±0.8),(3.2±0.7) mPa·s vs. (4.5 ± 1.2) mPa·s,3.0 ±0.4,3.1 ±0.7 vs.2.8 ±0.7,(1.2 ±0.2),(1.1 ±0.5) mPa·s vs.(1.8 ±0.6) mPa·s,(5.3 ± 0.8),(5.3 ±0.7) g/L vs.(4.7 ±0.8) g/L;control group:(7.9 ±0.8),(7.5 ±0.7)mPa·s vs.(8.2± 1.3) mPa·s,(4.5±0.4)、(4.5 ±0.4) mPa·s vs.(5.4±0.7) mPa·s,(3.7±0.8),(3.5±0.8 ) mPa· s vs. (4.6 ± 0.5 ) mPa· s,2.8 ± 0.6,2.9 ± 0.3 vs.2.7 ± 0.6,( 1.6 ± 0.4),( 1.7 ± 0.1 ) mPa· s vs.(1.9 ±0.8) mPa ·s,(5.0 ±0.9),(4.8 ±0.8) g/L vs. (4.7 ±0.5) g/L,P ＜0.05],and all the level of hemorheology in experiment group were improved compared with control group (P ＜ 0.05).There was no significant difference in 1,5 min Apgar scores between two groups (P ＞ 0.05).ConclusionThe epidural anesthesia and combined spinal epidural anesthesia can improve hemorheology of patients with PIH during cesarean section,but the combined spinal epidural anesthesia is more effective and favorable for pregnancy outcome.

Objective To compame the lumbar hemp-epidural block anesthesia choose different combination puncture point in pregnancy on laboratory intraoperative anesthetic effect.Methods 110 maternals classified for ASA Ⅰ～Ⅱof lactation,according to random number tables were divided into two groups,Ⅰ group lumbar puncture points for L2-3 clearance,Ⅱ group of lumbar puncture points to L3-4 clearance.Both groups the waist hemp-epidural joint block anesthesia downlink cesarean section,and two sets of anesthesia effect-acting period,after the baby born of 1 min Apgar score before anesthesia,the average arterial blood pressure(MAP)change,the lowest rate,adjust the number,surgical operation bed at the start of the plane,need anesthesia epidural anesthesia,medication found during hypotension and breathing difficulties incidence,intraoperative nausea and vomiting adverse events were compared.Results The operations of the two groups were successful,and there were no complications in postoperation maternal and newborn.Difficulty breathing rate,hypotension incidence,the incidence of nausea and vomiting were obviously higher than Ⅱ groups was statistically significant lying-in woman,difference(2 cases,1 case,x2=14.7,11.5,all P＜0.01).Need to adjust surgery beds in the number,epidural drugs significantly higher than the average Ⅱ group Ⅰ group(38.2%,47.3%,25.5%,x2=12.5,14.8,18.4,all P＜0.01).Conclusion In cesarean section in the operation,lumbar hemp-epidural joint block anesthesia choose L3-4 puncture,can reduce anesthesia cause nausea,vomiting hypotension,spinal cord injury and taper adverse reactions such as the incidence,in safer surgery under general anesthesia successfully completed cesarean section.

Objective To study the mechanism of interaction between neuronal nitric oxide syn-thase (nNOS) and inducible nitric oxide synthase (iNOS) following traumatic brain injury (TBI) in rats. Methods A total of 250 male Wistar rats were randomly divided into five groups, ie, sham oper-ation group, trauma group, 7-nitroindazole (7-NI) treatment group, aminoguanidine (AG) treatment group and combined AG and 7-NI treatment group. Severe closed TBI was made by using Marmarou meth-od. Protein expressions of nNOS and iNOS in hippocampus CAI were detected by means of immunohisto-chemical staining at 1,3, 6, 12 hours and at days 1,3, 7 and 14 after TBI. Results The expression of nNOS reached a peak at 6 hour after injury in all groups, with no statistical difference between groups (P > 0. 05), when there was no statistical difference between 7-NI treatment group and trauma group (P > 0. 05) but statistical difference in AG treatment group and combined AG and 7-NI treatment group compared with trauma group at 12 hours after TBI (P <0.05). The expression of iNOS reached maximal level at day 3 after TBI, with lower level in 7-NI group, AG treatment group and combined AG and 7-NI treatment group compared with trauma group (P < 0.05). Conclusions After TBI, nNOS interacts with iNOS by means of the feedback of nitric oxide. The enhanced expression of nNOS is initial factor for increase of iNOS expression, which can down regulate the expression of iNOS.

Objective To study the effects of different anesthesia methods on postoperative changes in T-lymphocyte subsets and IL-6、IL-10、TNF-α in the patients undergoing operation of stomach carcinoma.Methods 60 patients with stomach carcinoma were randomly divided into group I(general anaesthesia)and Ⅱ(general combined epidural anesthesia).The level of T-lymphocyte subsets and IL-6、IL-10、TNF-αt were respectively detected and compared before anesthesia,2 h after anesthesia,ld and 6 d after operation.Results CD3+ 、CD4+ 、CD4+/CD3+ decreased,but IL-6 increased at the end of 2 h after anesthesia,l d after operation compared with those before anesthesia(all P＜0.05).While IL-10、TNF-α had no statistical significance(all P＞0.05).At 6 d after operation,the values recovered to the level before anesthesia in two groups.Conclusion The immune function in patients with gastric cancer decreaseed after anesthesia,it was more serious in geteral anaesthesia than that of general combined epidural anesthesia.But anesthesia had little influence on inflammatory response.

Russia's post-degree medical education first appeared in the end of the 19th century and had improved along with the progress in science, technology and education. From 1990s, new waves of technology revolution and the rise of post-occupation training further pushed the post-degree medical education to move forward. Legally established post-degree education as a form of occupational education enables Russian medical professionals to constantly update knowledge and absorb new information to keep up with the new developments in medical science and technology. In this sense, post-degree medical education has become a major way to train not only medical professionals but professionals of acupuncture and moxibustion, and thus has been of great significance for TCM and acupuncture to transmit and develop in Soviet Union and Russia. This paper introduced the general situation of post-degree medical education in Russia, its influence to the transmission and development of TCM and acupuncture in Soviet Union and Russia, as well as the enlightenment to medical education.

Objective To explore the mechanism of neurotoxic effects of neuron nitric oxide synthase(nNOS)and inducible nitric oxide synthase(iNOS),and the therapeutic effects of 7-nitroindazole(7-NI)and aminoguanidine(AG),in traumatic brain injury(TBI)rats.Methods Two hundred and fifty adult male Wistar rats were randomly divided into 5 groups:sham operation group,traumatic group,AG group,7-NI group and AG+7-NI group.Animals in each group were divided into 8 subgroups according to the time after trauma(1,3,6,12 hours and 1,3,7,14 days).Severe diffused brain injury model was made with Marmarou method.Expressions of nNOS and iNOS in hippocampus CA1 region were determined by immunohistochemistry,nerve cells apoptosis in hippocampus CA1 region was observed by TUNEL methods,and the relationship between apoptosis and NOS was observed by double staining.Results In trauma group,the expression of nNOS in hippocampus CA1 region peaked at 6h post-trauma,the expression of iNOS and apoptosis of nerve cells in hippocampus CA1 region both peaked at 3d post-trauma,while the apoptosis was alleviated in AG group,7-NI group and AG+7-NI group.The number of both TUNEL staining and nNOS immunostaining positive cells increased at 6h post-trauma in trauma group,significantly higher than that in 7-NI group.The number of both TUNEL staining and iNOS immunostaining positive cells increased at 3d post-trauma in trauma group,significantly higher than that in AG group.Conclusions The over-expression of nNOS and iNOS has toxic effects to neural tissues of brain,serves as one of the factors inducing nerve cell apoptosis in hippocampus CA1 region.7-NI and AG can inhibit the expression of nNOS and iNOS,reduce the nerve cell apoptosis,and play an important role in neuroprotective effect.

Objective To compare the therapeutic results between low-molecular-weight heparin therapy and combined therapy of low-molecular-weight heparin and Shuxuetong for deep venous thrombosis (DVT) after lower extremity fracture.Methods Forty-two patients with DVT from 1,037 patients with lower extremity fracture treated from December 2010 through November 2012 were included in the study.There were 31 males and 11 females,aged from 26 to 82 years (mean,63 years).The patients were assigned to administration of 4,250 IU low-molecular-weight heparin subcutaneously,twice daily (Group A,n =19)and 4,250 IU low-molecular-weight heparin subcutaneously,twice daily plus shuxuetong to 6 ml intravenously,once daily (Group B,n =23) according to the random number table.A period of treatment was a week.Color Doppler sonography was performed to detect DVT.Results Longest course of treatment was 3 weeks.In Group A,the results were recanalization in 2 patients with mean time of 2.50 weeks,significantly effective in 3 patients with mean time of 2.67 weeks,effective in 7 patients with mean time of 3 weeks,and invalid or worse in 7 patients with mean time of 3 weeks.Whereas in Group B,the results were recanalization in 7 patients with mean time of 1.86 weeks,significantly effective in 12 patients with mean time of 1.83 weeks,effective in 3 patients with mean time of 3 weeks,and invalid or worse in 1 patient with mean time of 3 weeks (P ＜ 0.05).Conclusion Low-molecular-weight heparin plus Shuxuetong is effective in treatment of DVT after lower extremity fracture and hence can be as an option in clinical application.

Objective Ascending aortic dissection(AAD),for which the pathogenesis remains unknown,is life-threatening.Matrix metalloproteinase-9(MMP-9)and the pathological changes of vascular smooth muscle cells(VSMCs)have been reported to have roles the pathogenesis.The study examined the expression of matrix metalloproteinase-9(MMP-9)and the pathological changes of,VSMCs in patients with AAD.Methods AAD samples were taken from 35 patients(disease group)in acute phase during aortic replacement operation for AAD and control samples were corresponding part of ascending aorta(control group,n=21)collected from the donor hearts for transplantation.Transmission electron microscepe,hematoxylin-eosin(H-E)staining.Mallory staining were used for observing the pathological changes of VSMCs and matrix in the affected aortic wall.The immunohistochemicai staining of MMP-9 was carried out in both groups and semi-quantified by staining intensity analysis.The affected patients were further grouped according to the diameter of dissected aorta as with a AAD of <55 mm or with a AAD of≥55 mm.The associations of clinical factors,such as smoking status,hypertensive disease and aneurysm diameter,with the expression of MMP-9 were analyzed.Results Increased synthetic function of VSMCs with decreased density,disrupted elastic fibers and fibrosis in the dissected aortic wall were observed in the disease group,but not in the control group.MMP-9 was scarcely expressed in the aortic wall of the patients in the control group,though it was notably expressed in the VSMCs of disease group.Both subgroups presented more MMP-9 than the control group(both P<0.001).In the disease group,sub-group with a AAD diameter of ≥55 mm presented more MMP-9 than that with a diameter of <55 mm(P<0.05).MMP-9 expression was positively correlated with a history of hypertension(P<0.01)or a great aneurysm diameter(P<0.05).MMP-9 expression was not associated with age,smoking status or other clinical factors.Conclusion Increased secretion of VSMCs and the expression of MMP-9 induced by elevated blood pressure may lead to the destruction of matrix proteins.The resulting fibrosis of the aortic wall would decrease the tensile strength of the wall.When the fibrotic aortic wall dilated further,the increased expression of MMP-9 would aggravate the damage to the wall.It can be speculated that acute AAD would occur as a result of partial tearing of the aortic intima.
