The paper analyzes the current status of and problems in the development of non-government medical institutions in Shanghai, the advantages non-government medical institutions possess and the difficulties they face in the process of development. It advances the development orientation of non-government medical institutions, arguing that it is imperative to create circumstances and conditions for fair competition, formulate perfect supporting policies, and lead non-government medical institutions to the integration of their own development with the reform and development of the medical and health cause of the country. It argues, on the other hand, that non-government medical institutions must stress simultaneously the accumulation and the operation of capital so as to have a niche in the fierce competitions of the medical market.

Objective To assess the clinical significance of antibodies against cyclic citrullinated peptide(anti - CCP) in a cohort of patients with juvenile idiopathic arthritis (JIA). Methods The anti - CCP was tested by an enzyme linked immunosorbent assay (ELISA) in serum samples from 22 patients with JIA(9 boys, 13 girls), with a mean age of 9.1 years(range 1.1 - 16). As control groups, anti - CCP were also tested in sera of 20 healthy children, and 30 adult patients with rheumatoid arthritis(RA). Results Positive anti - CCP were found in sera of 2 patients with JIA(9.1 %), both with lower titre comparing with those of adult patients with anti - CCP positive. In the control groups, none of healthy children was positive for anti - CCP, but 16/30(53. 3%) adults with RA showed anti - CCP positivity. Conclusion Anti - CCP can be detected in children with JIA, but are less frequently present than in adults with RA, so anti - CCP has limited diagnostic value to JIA.

To improve the solubility of quercetin ( QT) , one of flavonoids that can inhibit the proliferation of vari-ous types of cancer cells, the novel amphiphilic polymer N-( 4-methylimidazole)-hydroxyethyl-chitosan ( MHC) , synthetized by chemical derivatization from chitosan, was used as the self-assembly micelles of QT. The formed polymer was characterized by 1 H NMR, elemental analysis and pyrene fluorescence spectrometry. The formulation of MHC micelles loading quercetin was optimized through single factor experiment. Then the optimized formulation was obtained as follows:the concentration of MHC was 0. 67% and the ratio of drug and carrier was 1 ∶10. The micelles particle size was ( 99. 21 ± 1. 71) nm, Zeta potential was +( 20. 01 ± 0. 72) mV and drug loading was ( 5. 42 ± 0. 32 )%. The in vitro release curve was investigated and was found to conform to Higuchi equation of Q=0. 1101 t1/2 -0. 064. The results of in vivo experiment showed that the mean rentention time and bioavail-ability of the MHC-QT micelles were 21. 42 h and 57. 49 μg h/mL, respectively, compared to 0. 30 h and 2. 50 μg h/mL of the free QT solution. These indicated that the MHC micelles could significantly improve the solubility of QT, the drug sustained-release effect and bioavailability, which would used as carrier for the anti-tumor drugs.

The general characteristics, outcomes and risk factors of the patients with aortic dissection (AD) were evaluated in a single medical center. From January 2002 to December 2008, 284 patients with AD were treated and followed-up at our institution, including 105 cases of type A AD and 179 cases of type B AD. The patients in each type were divided into three groups according to management: medical treatment group (A or B), open surgery group (A or B), and stent-graft group (A or B). The characteristics and follow-up outcomes were compared between the groups or subgroups. The results showed that there was significant difference in the prognosis for type A AD between medical treatment group and open surgery group, but there was no significant difference in the prognosis for type B AD between medical treatment group and stent-graft group. Independent risk factors of follow-up mortality for patients with type A AD included a history of atherosclerosis (HR, 3.807; 95% confidence interval [CI], 1.489 to 7.611; P=0.003), in-hospital hypotension/shock (HR, 4.687; 95% CI, 1.846 to 11.900; P=0.001), in-hospital myocardial ischemia or infarction (HR, 3.734; 95% CI, 1.613 to 8.643; P=0.002), pleural effusion (HR, 2.210; 95% CI, 1.080 to 4.521; P=0.030), branch vessel involvement (HR, 2.747; 95% CI, 1.202 to 6.278; P=0.016) and surgical treatment (HR, 0.177; 95% CI, 0.063 to 0.502; P=0.001). And there were insignificant independent predictors for mortality of the patients with type B AD. It was concluded that there were significant differences in characteristics and one year mortality between type A AD and type B AD, but after one year, there was no significant difference in the mortality and complications of them. There were several discordant risk factors of AD, such as female gender, age, thrombus, abrupt onset of pain that were considered as the risk factors in some papers. And there was no definite risk factor of mortality in this study in the patients with type B AD.

Objective To investigate the antidiabetic effect of Acanthopanax senticosus extracts based on metabonomics by UPLC-MS/MS and to explore its mechanisms. Methods The type 2 diabetes mellitus(T2DM)mouse model was established by inject-ing streptozocin(streptozotocin,STZ)in combination with alloxan. The effect of A. senticosus extracts on the fasting blood glucose of mice was observed. Multivariate statistical analysis was employed to analyze serum metabolites. The differential metabolites were iden-tified by online and self-built databases. MetPA Was employed to analyze the corresponding metabolic pathways. Results The T2DM model was established successfully. Compared with the model group,the fasting blood glucose of mice in the A. senticosus extracts groups decreased significantly. Compared with the normal control group,the level of phenylalanine,LysoPC(16:0,18:0),tyrosine, serine,urea andβ-hydroxybutyric acid inecreased,while the level of alanine,glutamine,leucine,valine and lactic acid decreased significantly in the model group. Pathway enrichment displayed that these metabolites were mainly involved in five metabolic pathways. The above-mentioned metabolites reversed to the normal level in varying degrees after administration of A. senticosus glycosides or poly-saccharoses extracts. Conclusion The extracts of A. senticosus display a significant hypoglycemic effect which might be achieved by regulation of amino acid,energy and lipid metabolism.

Objective To investigate factors related to chronic pain in those injured with fractures 27 months after the Sichuan earthquake.The correlation between intensity of pain and quality of life was also analyzed.Methods A total of 705 victims were investigated on site.Their residual pain was categorized using a visual analogue scale (VAS) score as no pain,mild pain,moderate pain or severe pain.The pain-related biological,psychological and social factors were analyzed using the Barthel Index ( BI ),Life Satisfaction Questionaire-11 ( LiSat-11 )and the SF-36 health questionnaire. Rehabilitation and surgical interventions,employment,income and emotional status were also investigated. Results The incidence of chronic pain was 88.5% in this population,of which mild pain and moderate pain were 35.7% and 33.3%,respectively.The percentage of the victims who had received fracture surgery was 65.8% ; the percentage of those who had recovered was 96.9%.BI scores for the victims without pain,with mild,moderate and severe pain were 92.7 + 10.2,92.8 + 8.4,91.2 ± 9.9 and 90.4 + 14.7,respectively ; the differences between these groups were all statistically insignificant.The influence of pain intensity on life satisfaction showed a significant linear trend.The percentages of the victims with restricted occupational ability in the four groups were 38.3%,61.5%,75.7% and 62.8% respectively.The median of personal annual income were ¥ 3550,¥ 2500,¥ 2000 and ¥ 2500.The VAS scores were significantly related to abnormal emotions,life satisfaction,employment and annual income.The subjects with different levels of residual pain also showed significant differences in the physical functioning,role-physical,bodily pain,general health,vitality,social functioning,role-emotional and mental health sub-scales of the SF-36.The total SF-36 scores were highest among victims without pain (70.6 + 17.5) and declined significantly in those with mild (61.3 + 14.3 ),moderate (52.7 + 14.3 ) and severe pain (52.3 + 14.7 ).This negative correlation between pain intensity and SF-36 total score was statistically significant. Conclusions Chronic pain remains common among fracture victims 27 months after the earthquake.Its intensity is correlated with psychological and social factors as well as quality of life.

AIM: To explore the probable mechanisms of diabetes-induced arrhythmias. METHODS: Diabetes was induced in male SD rats,using a single injection of alloxan into tail vein. Untreated age-matched animals were used as controls. All animals were observed by 2,4,6 and 8 weeks,respectively. Transmembrane potentials were recorded with conventional glass microelectrodes. RESULTS: Action potential duration(APD) at all level (APD10,APD20,APD30,APD50,APD70,APD90) was significantly lengthened in right ventricular papillary muscle from week 2 of diabetes. At week 8,APD was more lengthened at any level of repolarization than that at week 2. No differences were observed in the maximum rate of depolarization(V_ max ),overshoot(OS) and action potential amplitude(APA) as well as the resting membrane potential(RP) from the 2th to 8th week of diabetes. CONCLUSION: The results indicate that prolongation of APD may be prominently responsible for the increased incidence of cardiac re-entry-arrhythmias and sudden death,especially at late stages of diabetes.

Objective:To explore the preventive function for sweating gustatory syndrome and esthetic effect of restoring parotid gland area defect by using platysma flap. Methods: Nine patients who underwent parotidectomy and restored parotid gland area defect with platysma flap were analyzed retrospectively in this study. Observed whether there was an incidence of subjective sweating gustatory syndrome and introcession in the operation region. Results: There was no incidence of subjective sweating gustatory syndrome. Moreover, introcession in the operation region was not obvious. Conclusion: Restoring parotid defects with platysma flap can reduce introcession in the operation region. Application of platysma flap as an interpositional barrier between the skin flap and the parotid bed after parotidectomy can reduce the incidence of sweating gustatory syndrome.
