Objective Through investigating the situation of health care resources in Shanghai ,from the point of population and geographical area distribution, the article analyze the fair allocation of medical resources in Shanghai to provide the basis of decision-making in rational allocation of medical resources. Methods Use Lorenz curve and the Gini coefficient indicators, as well as Chain Proportion Method. Results The allocation of medical resources in population of Shanghai is fairly,and the trend of fairness will be enhanced. In the geographical allocation in space is more unfairness in Shanghai,and the fairness will be reduced. Conclusion The allocation of medical resources Municipal Population has few gap between urban and rural areas in the Shanghai which reached a fair comparison, but in the geographic distribution of has a larger gap between urban and rural areas. Most of the medical resources concentrated in large hospitals in the urban centers. The distribution of Medical resources should be rational and the health service system should be improved to improve medical and health service accessibility.

Objectives To develop a measurement for obesity assessment which could be used as a simple tool of risk screening. Methods The data of National Nutrition and Health Survey ( 2002 ) were used to analyze the relationship between body mass index ( BMI ), waist circumference (WC) and chronic diseases, based on which chronic disease index ( CRI ) was established. Receiver operating characteristic curve (ROC) was used to determine the cut-off of CRI and to compare the predictive effectiveness of CRI,BMI and WC on chronic diseases. The kappa test was chosen to estimate the consistency of different cut-off of CRI with BMI and WC. The odds ratios of chronic diseases in different cut-offs of CRI were calculated by multiple Logistic regression analysis. Results CRI was calculated as CRI = BMI + 3.5 WC. In ROC curve,the cut-off of CRI was 300. The predictive effectiveness of CRI was higher than that of BMI and WC. CRI at 300 showed the best consistency with 24 kg/m2 BMI and 85 cm WC (P <0. 05 ). In comparison with CRI <300,the risk of chronic diseases was significantly increased with an increase of 20 U CRI. Conclusion CRI shows good predietive effectiveness and could be used to identify those with higher risk of chronic diseases.

Objective To investigate the spatio-temporal expression of P2X3 receptor ( P2X3R) in rats with diabetic mechanical allodynia ( DMA ) .Methods DMA model in rats was induced by intraperitoneal injection of streptozocin ( STZ) .The von Frey filaments were applied to identify the changes of the paw withdrawal threshold ( PWT) in DMA rats.Immunofluorescence was employed to detect the spatio-temporal expression of P2X3R in the spinal dorsal horn (SDH), dorsal root ganglion (DRG) and hind paw skin on different time points after intraperitoneal injection of STZ , respectively.The protein expression of P2X3R in SDH and DRG was further semi-quantitatively analyzed by Western blotting.Results Compared with control group , intraperitoneal injection STZ induced significant mechanical allodynia indicated by the reduced PWT from 7 days, and which reached the peak on 14d and maintained to 28days (P<0.05). The expression of P2X3R in DRG neurons was significantly increased on 14 days and 21 days (P<0.05), while that in SDH and skin was markedly increased on 21 days and 28 days, compared with control group (P<0.05).Conclusion With the progress of DMA, the expression of P2X3R was significantly increased in the SDH, DRG and skin, which was almost parallel with the mechanical allodynia , but the changes in SDH and skin were 1 week later than that in DRG .These results suggest that P2X3R may play a key role in the maintenance of the DMA .

Objective To explore the effect of ultrasound-guided stellate ganglion block (SGB) in the incidence of postoperative headache, nausea and vomiting in conventional thyroidectomy. Methods Ninety patients undergoing conventional thyroidectomy were randomly allocated to three groups with 30 patients in each group. In group L, SGB was performed with 5 ml 0.5% lidocaine; in group N, SGB was performed with 5 ml 0.9% sodium chloride; and in group C, no prior block was performed. Postoperatively, during the 48 h after surgery, every episode of postoperative headache and postoperative nausea and vomiting was recorded and a safety assessment was performed. In group L and group N, the hemodynamic status of the vertebral artery and carotid artery was recorded before and after the SGB was performed. In group C, the hemodynamic status of the vertebral artery and carotid artery was recorded before and after the neck was in the full extension position. Results One patient of group N and one patient of group C was discharged. During the 48 h after surgery, headache occured in 5 patients (16.7%) of group L, 8 patients (27.6%) of group N, and 17 patients (58.6%) of group C, and the headache rate in group C was significantly higher than that in group L (P=0.0007). The headache mostly occurred at 2 h and 4 h after operation. During the 48 h after surgery, nausea and vomiting occured in 8 patients (26.7%) of group L, 11 patients (37.9%) of group N, and 20 patients (60.9%) of group C, and the nausea and vomiting rate in group C was significantly higher than that in group L (P=0.0017) and group N (P=0.0343). The nausea and vomiting mostly occurred at 2 h and 4 h after operation.In group L and group N, and the inner diameters of the vertebral and carotid arteries after SGB were wider than those before SGB (P<0.05). In group C, the inner diameters of the vertebral and carotid arteries after the neck extension position were narrower than prostration position (P<0.05). No side effects were observed during or after SGB. Conclusions Preoperative SGB performed with 5 ml 0.5%lidocaine is an effective technique for reducing postoperative headache and nausea and vomiting after thyroidectomy.

Objective To explore the risk association of ABCA1-V771M polymorphism with coronary heart disease (CHD) in Hart nationality in Northwest of China. Methods With case-control study, ABCA1-V771M polymorphism was detected in 204 unrelated Hart nationality people in Northwest of China, and all the subjects by coronary angiography were grouped into 106 cases and 98 controls. The genotypes and alleles frequency distribution of ABCA1-V771M polymorphisms were analyzed by PCR-RFLP analysis, and the clinical statistics of serum lipids were compared and its effects of ABCA1-V771M polymorphism on the plasma lipid levels and coronary atherosclerotic heart disease were analyzed. Results The genotypic frequencies of ABCA1-V771M polymorphism matched well under Hardy-Weinberg equilibrium (P>0.05), V and M allelic frequencies were 33.3% and 66.7%. In comparison with VV+VM genotype carriers, MM genotypes carriers had much lower plasma levels of HDL-C (P<0. 001) and much higher plasma levels of TG (P<0. 05). M allelic frequency in CHD group was significantly higher than V allelic frequency (P<0. 05). M allele was related with more severity of atherosclerosis in the coronary artery than V allele (P<0.05). However, there was no obvious difference in the incidence of AMI among carriers with three genotypes of ABCA1-V771M polymorphism (P>0.05). Conclusion ABCA1-V771M polymorphism was not only associated with the plasma levels of HDL-C and TG, but also related to the susceptibility and severity of coronary atheroselerotic heart disease. Moreover, M771 allele appeared to be atherogenie among Han population in Northwest of China.
