Objective: To analyze the risk factors of hyperuricemia (HUA) and its outcomes of renal function in patients with diabetes mellitus in Shanghai. Methods: A total of 3 454 patients with diabetes who were admitted to the Shanghai Diabetes Clinical Center from July 2011 to September 2014 were selected. The prevalence of HUA, predisposing factors and renal function of diabetic patients were analyzed. Patients were divided into HUA group (n=548) and normal serum uric acid (SUA) group (n=2 906). General characteristics and clinical parameters of diabetic patients were compared between two groups. Pearson correlation analysis and multivariate Logistic regression were used to analyze the relationship between SUA and renal dysfunction and abnormal proteinuria in diabetic patients. Results: In Shanghai patients with diabetes, the prevalence of HUA was 15.87%, 14.52% in men, 17.80% in women. Glomerular filtration rate (GFR), fasting C-peptide, gender, age, natural logarithm of the ratio of microalbuminuria to creatinine (LnACR), glycated albumin (GA), triacylglycerol (TAG), high density lipoprotein cholesterol (HDL-C) and body mass index (BMI) were independently associated with SUA (all P<0.05). In diabetic patients with HUA, 1-SD increment in the SUA level was associated with a 0.8% increased prevalence of renal dysfunction, 0.3% increased prevalence of incident abnormal albuminuria and 0.5% decreased prevalence of hyperfiltration (all P<0.05). Conclusion: Diabetes has an important impact on HUA. Actively improving insulin resistance and controlling blood glucose may improve HUA. HUA is an independent risk factor for the occurrence and development of diabetic nephropathy. Therefore, monitoring the level of SUA in diabetic patients is of great significance in the prevention of diabetic nephropathy.

Objective To investigate the role of autophagy in radiation-induced death response of human nasopharyngeal carcinoma cells.Methods MTT method was used to detect cell viability of CNE-2 cells in different time after irradiation.Clonogenic survival assay was used to evaluate the effect of autophagy inhibitor (chloroquine phosphate) and autophagy inductor (rapamycin) on radiosensitivity of nasopharyngeal carcinoma cells.Cell apoptosis was assessed by flow cytometry.The expressions of LC3 and P62 were measured with Western blot.Cell ultrastructural analysis was performed under an electron microscope.Results Irradiation with 10 Gy induced a massive accumulation of autophagosomes accompanied with up-regulation of LC3-Ⅱ expression in CNE-2 cells.Compared with radiation alone,chloroquine phosphate (CDP) enhanced radiosensitivity significantly by decreasing cell viability (F =25.88,P ＜ 0.05),autophagic ratio (F =105.15,P ＜ 0.05),and LC3-Ⅱ protein level(F =231.68,P ＜0.05),while up-regulating the expression of P62 (F =117.52,P ＜ 0.05).Inhibition of autophagy increased radiation-induced apoptosis (F =143.72,P ＜ 0.05).Rapamycin (RAPA) also significantly decreased cell viability,but increased autophagic ratio and LC3-Ⅱ protein level while down-regulated the expression of P62.Induction of autophagy increased radiation-induced apoptosis(F =167.32,P ＜ 0.05).Conclusions Blockage of autophagy with CDP could enhance radiosensitivity in human nasopharyngeal carcinoma cells,suggesting that inhibition of autophagy could be used as an adjuvant treatment to nasopharyngeal carcinoma.

Methods In 40 cases with NHL,LDH was measured by L-P continuous monitoring method,?_2-MG was measured by luminescent immunoassay,D-dimer was measured by immunoturbidimettic assay.Results The levels of the blood LDH,?_2-MG and D-dimer in patients with NHL were higher than those of in the controls(P 0.05).Con- clusion The levels of blood LDH,?_2-MG,D-dimer can be taken as an auxiliary clinical index to diagnose, classify the phase,evaluate the effectiveness of treatment and prognosis in the NHL patients,and have impor- tant clinical significance.

Objective: To observe the clinical efficacy of herbal cake-partitioned moxibustion for dysmenorrhea due to deficiency cold. Methods: A total of 70 patients with dysmenorrhea who met the inclusion criteria were randomized into a mild moxibustion group and a herbal cake-partitioned moxibustion group by the random number table, with 35 cases in each group. Shenque (CV 8), Zhongji (CV 3) and bilateral Zigong (EX-CA 1) were selected for both groups. The treatment continued for 3 menstrual cycles. The visual analog scale (VAS) and COX menstrual symptom scale (CMSS) were scored in both groups before treatment, after treatment and at the end of the 3rd menstrual cycle after treatment. The clinical efficacy was evaluated at the end of the 3rd menstrual cycle after treatment. Results: After treatment, the clinical efficacy of the herbal cake-partitioned moxibustion group had the tendency to be superior to that of the mild moxibustion group, while there was no statistically significant difference in the overall efficacy between the two groups (P>0.05). The VAS and CMSS scores after treatment and at the follow-up were significantly lower than those before treatment in both groups (all P<0.05). At the follow-up, the VAS scores in both groups had no significant intra-group differences from those after treatment (both P>0.05). The CMSS scores in both groups were significantly lower than those after treatment (both P<0.05). The VAS scores at the follow-up of both groups had no statistical differences from those after treatment (both P>0.05). After treatment, the CMSS score in the herbal cake-partitioned moxibustion group was significantly lower than that in the mild moxibustion group (P<0.05). At the follow-up, there were no statistical differences in the CMSS score between the two groups (P>0.05). Conclusion: The herbal cake-partitioned moxibustion has the same therapeutic efficacy for dysmenorrhea as the mild moxibustion; the two moxibustion methods can significantly improve the concomitant symptoms of dysmenorrhea, and the herbal cake-partitioned moxibustion is little better.

Based on the international large-scale epidemiological research results, the Joint United Nations Programme on HIV and AIDS (UNAIDS) has proposed three 90%-90%-90% strategies for AIDS prevention and control, and the major countries in the world are actively promoting it. However there is a big gap in the strategy to promote the treatment of newly diagnosed HIV-positive people because of insufficient research on the acceptance and continuum care and treatment behavior of newly diagnosed person. Domestic and foreign studies have reported that diagnose outcome may cause psychological problems under pressure. Men who have sex with men with HIV infection are more stressed than the general population for their sexual orientation and HIV infections. Depression and anxiety are common mental problems which were present in 70.7% of the population, especially among newly diagnosed MSM. Unstable emotional state and unhealthy psychological condition may effect on their sleep, seeking treatment behavior and other aspects. The bi-directional affect between sleep and emotion has been proved, while the function of emotional state impact on HIV infection MSM ignition and retention ART is still unclear yet. This paper reviews treatment behavior status of men who have sex with men with HIV diagnosis, and both the effects of emotional state and sleep disorder on their treatment behavior, also analyzes and interprets the relationship between sleep disorder and emotion. This paper may contribute to provide new ideas and basis for HIV prevention and treatment among risky population and also for the care of HIV positive people.

Objective: This study aims to evaluate the prevention effect and cost-effectiveness of a prophylactic bivalent human papilloma virus (HPV) vaccine. Methods: A multiple health status dynamic model was developed, including natural history of diseases and prevention strategies. We built 19 prevention strategies including visual inspection with acetic acid/lugol's iodine (VIA/VILI) and/or 3 does prophylactic bivalent HPV vaccine administered to adolescent girls at the age of 15 years old every year under the assumption that vaccine coverage and screening coverage were 70%. The incremental cost-effectiveness ratio (ICER), optimal price of 3 does vaccine and cost-effectiveness frontier of these strategies were analyzed compared with no-intervention. The ICER threshold is 152 087 CNY. Results: Compared with no-intervention, Routine vaccination reduced the incidence of cervical cancer by 69.5%, superior to 5 strategies including VIA/VILI screening only. The range of effect was between 9.0% and 69.2%, and the effect of strategy increased significantly with the increase of screening frequency. Combination vaccination with screening at ages of 35 reduced the incidence of cervical cancer by 72.0%, and the effect increased with the increase of screening frequency. Combination vaccination with screening every 3 years between (35-64) years old reduced the incidence by 89.4%. Compared with no-intervention, the ICER of combination vaccination with screening twice between 35 years and 64 years was 121 292 CNY/life-year, which was cost-effective. The price of vaccine had a significant impact on the ICER of the strategy; when the vaccine price was less than 600 CNY, only routine vaccination or supplementary vaccination between 16-39 years old after routine vaccination was cost-effective; when the vaccine price was less than 1 200 CNY, supplementary vaccination between 16-19 years old plus VIA/VILI was cost-effective. Conclusion Ther prevention strategy was cost-effective, which could effectively reduce the incidence of cervical cancer by implementation of HPV vaccination combined with VIA/VILI in suitable aging females.

OBJECTIVETo observe the differential effect of joint ultrasound on the syndrome differentiation of rheumatoid arthritis (RA) by observing the high frequency ultrasound performances among inactive stage and different syndromes in active stage.

METHODSTotally 83 RA patients in the active stage were assigned to the dampness heat syndrome group (DHS, 59 cases)and the cold dampness syndrome group (CDS, 24 cases) according to Chinese medicine (CM) syndrome typing. Besides, 20 RA patients in the remission stage were recruited as the control group (abbreviated as the remission group). By using high frequency ultrasound and power Doppler ultrasound technology, a comparative observation of synovitis, tenosynovitis, synovial blood flow, and bone erosion in the 2nd-5th metacarpophalangeal (MCP) joints, proximal interphalangeal (PIP) joints, wrist joints, knee joints, the second and the fifth metatarsophalangeal (MTP) joints (a total of 24 joints) was performed in all patients. Correlation analyses were performed between the ultrasound performance, laboratory indices, and the disease activity. Ultrasound data of each RA patient were analyzed by their total scores. Χ2 test was used for enumeration data. The measurement data was expressed as x ± s. One-way ANOVA was used for data of normal distribution, while non- parametric test was used for data of non-normal distribution. Correlation analysis of two variables was performed for clinical indicators and ultrasound indicators. Its significance was detected using Pearson correlation.

RESULTSCompared with the remission group, the severity degree of synovitis, tenosynovitis, synovial blood flow, and bone erosion significantly increased in the DHS group (P < 0.01). There was statistical difference in ESR, CRP, anti-CCP, DAS28 score, and the positive rate of RF (P < 0.05, P < 0.01). There was statistical difference in the severity degree of synovitis and synovial blood flow, and DAS28 score in the CDS group (P < 0.05). Compared with the CDS group, there was statistical difference in the four ultrasound indices (P < 0.05, P < 0.01), ESR, CRP, anti-CCP, DAS28 score, and the positive rate of RF in the DHS group (P < 0.05, P < 0.01). There was no statistical difference in G, IgG, IgA, or IgM among the three groups (P > 0.05). There existed positive correlation between ESR and the synovitis degree, synovial blood flow, and bone erosion in the DHS group (r = 0.444, 0.397, 0.486, P < 0.05).There existed positive correlation between ESR and the synovitis degree, bone erosion, and synovial blood flow in the DHS group (r = 0.378, 0.270, P < 0.05). There existed positive correlation between the DAS28 score and the synovitis degree and synovial blood flow in the DHS group (r = 0.304, 0.351, P < 0.05).

CONCLUSIONSThe inflammation degree was the most severe in RA patients of DHS. High frequency ultrasound could provide better evidence for Chinese medical syndrome differentiation of RA patients.

OBJECTIVEGas chromatography (GC) was used to investigate the cellular fatty acid (CFA) composition of 141 Acinetobacter baumannii and 32 A. calcoaceticus isolates from different locations in China and to find chemical markers to differentiate these two closely related bacteria.

METHODSWhole cell fatty acid methyl esters (FAMEs) were obtained by saponification, methylation, and extraction for GC analysis, followed by a standardized Microbial Identification System (MIS) analysis.

RESULTSAll A. baumannii and A. calcoaceticus strains contained some major fatty acids, namely, 18:1 ω9c, 16:0, Sum In Feature 3, 12:0, 17:1ω8c, 3-OH-12:0, 17:0, Sum In Feature 2, 2-OH-12:0, and 18:0 compounds. Although most of the total CFAs are similar between A. baumannii and A. calcoaceticus strains, the ratios of two pairs of CFAs, i.e., Sum In Feature 3/18:1 ω9c versus 16:0/18:1 ω9c and Sum In Feature 3/18:1 ω9c versus unknown 12.484/18:1 ω9c fatty acids, could differentiate these two closely related bacteria. A. baumannii could be easily classified into two subgroups by plotting some ratios such as Sum In Feature 3/16:0 versus 17:0 and Sum In Feature 3/2-OH-12:0 versus 17:0 fatty acids.

CONCLUSIONThe ratios of some CFAs could be used as chemical markers to distinguish A. baumannii from A. calcoaceticus.
