Objective To estimate fairness in the financial contributions of suburban households of Shanghai to the health system and the situation throughout the country. Methods A household survey was conducted to obtain data on health expenditure and government health input, which was then analyzed by means of the index for and methodology of fairness in the financial contributions of households in the performance assessment of the health system as introduced by the WHO. Results The coefficient of fairness in the financial contributions of households to the health system was estimated to be 0.735 and the rate of cooperative medical care coverage was positively related to the fairness. Conclusion The fairness level of the financial contributions of suburban households of Shanghai to the health system tallies with the level estimated by the WHO for China while the national level is lower. The calculations of government subsidy for household health, as recommended by the WHO in estimating fairness in the financial contributions to the health system, do not conform to the actual situation in China.

Objective To explore the cause and effective management and prevention of septic shock after minimally invasive percutaneous nephrolithotomy (MPCNL) in the elderly.Methods Clinical data of 13 patients with septic shock after MPCNL in our hospital were retrospectively analyzed,and the cause,prevention and treatment of septic shock were investigated.Results The incidence of septic shock in patients undergoing MPCNL was 3.54％ in this study.Single-factor analysis and logistic regression analysis showed that the risk factors for post-MPCNL septic shock were female and the history of diabetes (both P＜0.05).Conclusions Septic shock is a serious complication after MPCNL.Intensive perioperative prevention measures can reduce the incidence of septic shock.Early diagnosis and proper treatment are the keys to successful treatment of septic shock.

Objective To analyze and investigate clinical characteristics, pathogenesis and treatment of urinary tract infection and aseptic meningitis. Methods Clinical features and laboratory tests of a two-month-old baby girl with urinary tract infection and aseptic meningitis were reported. Results The patient complained of fever, neck stiffness and a bulging fontanel, accompanied by congestion and abnormal secretion of urethra. The cerebrospinal lfuid (CSF) white blood cell count was 30×106/L. The blood culture and the CSF culture were both negative. And the urine culture was positive for Enterococcus faecium. The patient received a 10-day course of intravenous antibiotic therapy. The prognosis is good with no recurrence of the disease. Conclusions Aseptic meningitis can be concomitant with urinary tract infection, The probable hypothesis may be that sterile CSF pleocytosis is mediated by urinary tract infection. Knowledge of this may prevent unnecessary antibiotics therapy for presumed bacterial meningitis.

Objective To study the architecture of the subpleural pulmonary microvasculature and its functional relationship in the bactrian camel. Methods The replica scanning electron microscopic method was used. Results According to their continuous branches,the subpleural pulmonary microvasculatures were recognized into four grades: arteriole,terminal arteriole,precapillary arteriole and capillary.The subpleural pulmonary capillaries generally came from the subpleural precapillary arteriole and communicated each other to form the subpleural pulmonary capillary network.Sometimes,the subpleural terminal arteriole directly gave rise to capillaries to unite with the subpleural pulmonary capillary network.The network was loose,in which the diameter of the mesh was larger than that of the capillary,and the mesh was often hexagon and pentagon in appearance.There were obvious imprints of the smooth muscles on the surface of the casts of the subpleural pulmonary arteriole,the terminal arteriole and the precapillary arteriole.On the surface of the casts of the subpleural pulmonary capillary,there were obvious imprints of the endothelial nuclei as well.In addition,the broad and different level communications were found among the pulmonary interstitial capillary and subpleural pulmonary microvasculature.Conclusion There were no significant differences on the architecture of the subpleural pulmonary microvasculature between the bactrian camel and other kind of mammals.

Objective:To study the effects of soybean phospholipids on learning and memory abilities and contents of fatty acids in hippocampus of mice and its mechanism. Method:Mice were randomly divided into four groups:low dose(2.5g/kg) ,middle dose(5.0g/kg) and high dose(10.0g/kg) groups of soybean phospholipids and control group. The treatment groups were fed with soybean phospholipids every day while the control group with distilled water for 30 d.After learning and memory abilities were measured,the mice were killed and contents of fatty acids in hippocampus of mice were determined by high performance liquid chromatography(HPLC) . Results:(1) The learning and memory abilities of mice in middle and high dose groups were significantly improved,but only memory abilities in low dose groups were stronger than control group.(2) The contents of protein in hippocampus in middle and high dose groups were increased extremely.(3) The contents of oleic acid(C18:1) and docosahexaenoic acid(DHA,C22:6 ) were obviously enhanced in hippocampus of high dose group;but decreased in eicosapentaenoic acid(EPA,C20:5) and linoleic acid(C18:2) . The content of DHA was increased and EPA decreased significantly in middle dose group.The increase of arachidonic acid(C20:4) was not significant.Conclusion:Soybean phospholipids may improve learning and memory abilities,which might contribute to change of fatty acids contents in hippocampus of mice.

Objective To investigate the protective mechanism of hydrogen sulfide(H2S) on inflammatory and oxidative damage of myocardium due to stress after amputation,and explore the relationship between H2S signal pathway and inflammatory and oxidative damage.Methods Twenty-eight adult male Wistar rats(weighing 260-300g) were randomly divided into 4 groups(7 each):control group,trauma group,NaHS group and PPG group.Rat model of traumatic stress was established in the rats in the 3 latter groups,and the animals were sacrificed 6 hours after modeling.The rats in control group were also sacrificed at the same time point.Rats in NaHS and PPG group respectively received intraperitoneal injection of NaHS(28?mol/kg) or PPG(50mg/kg).The level of H2S in plasma was measured by sensitive sulphur electrode,the activity of CSE in myocardium was determined by methylene blue method,myeloperoxidase(MPO) in plasma and myocardium was measured with ultraviolet spectrophotometry,and malondialdehyde(MDA) in plasma and myocardium was measured by TBA method.Results Compared with the control group,the content of H2S in plasma decreased,MPO and MDA in plasma and myocardium increased 6 hours after amputation(trauma group).Compared with the trauma group,the contents of H2S and MPO in plasma and the activity of CSE in myocardium increased,MDA in plasma and MPO and MDA in myocardium decreased in NaHS group,while the contents of H2S and MPO in plasma and the activity of CSE in myocardium decreased,MDA in plasma and MPO and MDA in myocardium increased in PPG group.Conclusion Inflammatory and oxidation injuries may occur in rat's myocardium after amputation,and H2S can offer a protective effect on myocardium by decreasing inflammatory and oxidative damage.
