Objective:To observe the clinical effect of treatment of burning mouth syndrome in women by hormone replacement therapy (HRT).Methods:21 cases of climacteric women with burning mouth syndrome (BMS) were treated by HRT with nilestriol and medroxyprogesterone acetate.Another 21 cases were treated with vitamin B,C and oryzanol as the controls.The treatment and follow-up were conducted for 3～6 months.Results:The ratio of effectiveness in HRT group and control group was 85.71% and 14.27% (P

Objective To determine blood/gas and tissue/gas partition coefficients of sevoflurane, isoflurane and halothane and evaluate the effects of pregnancy on them. Methods Ten 18-22 day pregnant and 10 non-pregnant SD rats were killed under pentobarbital anesthesia. The tissue specimens of heart, liver, kidney and brain were obtained and made into homogenates respectively. The blood/gas and tissue/gas partition coefficients of sevoflurane, isoflurane and halothane were determined using a method of 2-stage headspace equilibration by gas chromatography. Results Blood/gas and brain/gas partition coefficients were lower in pregnant group than in non-pregnant group (P

Objective To investigate the effects of adenosine postconditioning (AP) on serum IL-10 and TNF-α concentrations following myocardial ischemia-reperfusion(VR)in rats.Methods Twenty-four SD ratsweighing 180-250 g were randomly divided into 4 groups(n=6 each):group I sham operation (group S);group Ⅱ myocardial I/R;group Ⅲ ischemic postconditioning(group IP)and group Ⅳ AP.Myocardial I/R was induced by 30 rain occlusion of anterior descending branch of left coronary artery followed by 120 min reperfnsion.IP was induced by 3 cycles of 30 s myocardial ischemia followed by 30 s reperfusion at the end of ischemia.In AP group adenosine 1.5 mg/kg was infused at 40μg·kg-1·min-1 before the onset of reperfusion.SP,DP and HR were recorded before ischemia (baseline) at 30 min of ischemia and 30 and 120 min of reperfusion.Arterial bloodsarnples were collected at 120 min of repednsion for determination of serum TNF-α and IL-10 concentrations.Theanimals were then killed.Their hearts were removed for microscopic examination.Myocardial infarct size wasmeasured and myocardial MDA content was determined.Results BP and HR were signilicandy decreased duringreperfusion while myocardial infarct size.MDA content and serum concentrations of IL-10 and TNF-α weresignificantly increased in I/R group compared with group S.Ischemic and adenosine postconditioning significantlyattenuated hypotension,reduced infarct size,myocardial MDA content and serum TNF-α concentration and increased serum IL-10 concentration in group AP and IP as compared with I/R group.There was no significant difference in the above changes between group AP and IP. Myocardial injury was ameliorated in group AP and IP as compared with I/R group. Conclusion Adenosine postconditioning can protect myocardium from I/R injury by increasing IL-10 production and inhibiting TNF-a release.

Objective To investigate the effect of PEP-1-heme oxygenase-1 (PEP-1-HO-1) fusion protein transduction on hypoxia-reoxygenation (H/R) injury in rat H9c2 cells. Methods After construction of the prokaryotic expression plasmid pET15b-PEP-1-hHO-1 containing the human heme oxygenase-1 gene, it was then transformed to make PEP-1-HO-1 fusion protein express. The H9c2 cells were cultured in high-glucose Dulbecco's modified Eagle's medium (DMEM) supplemented with 15% fetal bovine serum and randomly divided into 4 groups (n = 4 each): control group (group C), H/R group, low-concentration fusion protein group (group L-HO), and high-concentration fusion protein group (group H-HO). The cells were exposed to 22 h of hypoxia followed by 8 h of reoxygenation. PEP-1-HO-1 fusion protein was added to the culture medium with a final concentration of 1.0 μ mol/L (group L-HO) or 2.0 μmol/L (group H-HO) before hypoxia. The cells and supernatant of the culture medium were collected after reoxygenation to determine the activity of lactate dehydrogenase (LDH) in the supernatant and the content of malondialdehyde (MDA) and activity of superoxide dismutase (SOD) in the cells. Results The SOD activity was significantly lower, while the MDA content and LDH activity were significantly higher in group H/R, L-HO and H-HO than in group C (P ＜0.05). The SOD activity was significantly higher, while MDA content and LDH activity were significantly lower in group L-HO and H-HO than in group H/R, and in group H-HO than in group L-HO ( P ＜ 0.05). Conclusion PEP-1-HO-1 fusion protein transdution can protect H9c2 cells against H/R injury in rats.

Objective To evaluate the role of the complement 1 q (C1 q) in hepatic ischemia-reperfusion (I/R) injury in rats.Methods Sixty healthy male Sprague-Dawley rats,aged 3-4 months,weighing 180-200 g,were randomized into 2 groups:sham operation group (S group,n =12) and hepatic I/R group (I/R group,n =48).Hepatic specimens were obtained at 1,3,6 and 24 h of reperfusion and were then cut and stained with haematoxylin and eosin for examination of histological changes of the liver (with light microscope) and for determination of superoxide dismutase (SOD) activity and malondialdehyde (MDA) content (by colorimetric method),expression of Clq mRNA (using real-time PCR) and expression of Clq (by using Western blot).Results Compared with S group,the activity of SOD was gradually decreased,the content of MDA was gradually increased,and the expression of Clq and Clq mRNA was gradually up-regulated and peaked at 3 h of reperfusion with the prolongation of reperfusion time in I/R group (P ＜ 0.05).The pathological changes of the liver were aggravated with the prolongation of reperfusion time in I/R group.Conclusion Activation of C1 q is involved in hepatic I/R injury in rats.

Dynamic and sustainable fundraising strategies are the prerequisite for the long-term and stable development of the New Rural Cooperative Medical Scheme(NRCMS).The paper analyzed the current situation and problems of NRCMS' fundraising,and proposed the principles for designing a sustainable financing strategy of NRCMS,and then its fundraising strategy.First,clarification of its fundraising sources and rational division of the sharing ratio of the funding bodies (individuals contributions account for 20％of the per capita fundraising) ; second,linking fundraising levels with net per capita net income(5 ％ ～ 6 ％) of peasants; third,expansion of the service scope and level coordinated within NRCM.

Objective To explore the effect of Quality Control Circle(QCC) on patients in the recovery phase with post stroke depression at rehabilitation therapy.Methods 80 patients in the recovery phase with post stroke depression were collected.According to the digital table, they were randomly divided into control group and QCC group,40 cases in each group.All the patients got treatment as rehabilitation medical care routine, rehabilitation exercise and medical treatement.And patients of QCC group received extra QCC management.The activities of daily living(Barthel Index Scale),severity of depression(Hamilton Depression Scale HAMD),rehabilitation exercises compliance were evaluated in the two groups.Results After intervention, the scores of ADL,HAMD and rehabilitation exercises compliance in the control group were (33.50±6.22)points,(22.23±3.30)points,(2.70±1.32)points,respectively,which in the QCC group were (54.13±8.84)points,(14.75±4.14)points,(4.45±0.90)points,respectively.The scores of activities of daily living(ADL)(t=15.06,26.03,all P<0.01) and rehabilitation exercises compliance(t=1.78,12.2,all P<0.01) had been improved, which in the QCC group was more obvious(t=12.10,6.90,all P<0.01)).The depression scores in both two groups were decreased(t=13.35,25.78,all P<0.01),and the decrease in the QCC group was significantly higher than that in the control group(t=8.93,P<0.01).Conclusion QCC application in post stroke depression at the recovery phase can effectively reduce the degree of depression, improve patients' ADL and rehabilitation exercise compliance.

Based on a description of the evolution,main reform practices and effects of public hospital payment system reforms,this paper focused on analyzing the existing problems found in the reforms.Such problems namely include lack of scientific and reasonable design of payment standards,lack of systemic and coordinated system reforms,and failure to fully mobilize the enthusiasm of medical workers to participate in the reforms,as well as other underlying causes.Based on such suggestions were put forward to promote public hospital payment system reforms,as negotiation of the payment standard between purchasers and providers,combined approaches in innovation in payment methods,advancing systemic payment system reform,and establishing a transmission mechanism of incentive to the medical personnel.
