OBJECTIVETo observe the neurological protection effects of "paraplegia-triple-needling method" on rats with incomplete spinal cord injury (SCI), so as to make a preliminary exploration on its mechanism.

METHODSA total of 45 SD rats were randomly divided into a paraplegia-triple-needling method group (group A), a regular acupuncture group (group B) and a model group (group C), 15 rats in each one. The rats model of incomplete spinal cord injury was established by modified Allen's method. The acupoints of governor vessel and back-shu points next to the vertebras of upper end and lower end of injured segment as well as motor points in key muscle of lower extremities were treated with acupuncture in the group A; the acupoints of governor vessel and back-shu points next to the vertebras of upper end and lower end of injured segment as well as "Huantiao" (GB 30), "Housanli" (ST 36), "Yanglingquan" (GB 34) and "Genduan"(Extra) were treated with acupuncture in the group B; rats in the group C received no treatment after model establishment but grabbing and immobilization. The needles were retained for 15 min in the group A and group B, once a day for 14 times. 1 d, 7 d and 14 d after model establishment, Basso Beattie Bresnahan (BBB) scores were observed in each group; the morphologic change of injured spinal cord and expression of positive cells of calcitonin gene-related peptide (CGRP) were observed. Results (1) One day after SCI, there was no significant difference of BBB scores among three groups (P> 0. 05); 7 days and 14 days after SCI, BBB scores in the group A and group B were significantly superior to those in the group C (all P<0. 05), and the BBB scores in the group A were superior to those in the group B ( both P<0. 05). (2) There was expression of CGRP positive cells in all three groups, and that in the group A and group B was significantly higher than that in group C (both P<0. 05); 14 days after treatment, the expression in the group A was higher than that in the group B (P<0. 05).

CONCLUSIONThe "paraplegia-triple-needling method" could obviously! improve the motor function of rats with SCI, especially the expression of neuroprotective factor CGRP, which is likely to be one of the mechanisms of neurological protection effect.

The World Health Organization (WHO) released the Global Health Sector Strategy 2016, which explicitly proposes a 90% reduction in the new hepatitis B virus (HBV) infection rate and a 65% reduction in HBV-related mortality by 2030. However, at present, there are still 296 million chronic hepatitis B virus-infected patients worldwide, and nearly 900,000 patients die every year from cirrhosis and liver cancer caused by HBV infection. Antiviral treatment for chronic hepatitis B virus infection can effectively inhibit HBV replication, reduce liver inflammation and necrosis, effectively block and reverse liver fibrosis, and even early cirrhosis, thereby lowering cirrhosis-related complications, liver cancer, and liver disease-related mortality. Although the domestic and foreign guidelines have gradually eased antiviral treatment indications for chronic hepatitis B, there are still a considerable number of chronic hepatitis B patients with nonconformity who cannot receive antiviral treatment because they do not meet the existing standards, resulting in the progression of more severe diseases. This study analyzed the prevalence of hepatitis B, the therapeutic effect of antiviral drugs, domestic and international guideline treatment standards, the assessment of key indicators changes in the guidelines, comprehensively considered the coverage rate and treatment standards for antiviral treatment, and explored the changes in disease burden and cost-effectiveness following increasing the coverage rate and reducing treatment thresholds in order to achieve the global strategic goal of eliminating hepatitis B as soon as possible as a public health threat.

Objective In this study, we aimed to translate and revise the Summary of Diabetes Self-Care Activities( SDSCA) and the Confidence In Diabetes Self-care( CIDS) scales, to test the reliability and validity of the two scales in Chinese adult type 1 diabetes( T1D) patients. Methods In the first step, Chinese versions( C-SDSCA and C-CIDS) were developed conceptually equivalent to the English versions. And the investigation was conducted in 100 patients from Guangdong T1D Translational Medicine Study. 15 of them were randomly chosen to be retested 4 weeks later. Cronbach's α were used to assess reliability, and factor analysis to its validity. The relationship between scores of C-SDSCA and C-CIDS were analyzed using Spearman correlation analysis. Results The overall Cronbach's α of C-SDSCA was 0.72 and the retest reliability was 0.95( sub-scale:0.67-1.00) . 4 common factors were extracted by factor analysis, and the cumulative contribution was 87.39％. As for C-CIDS, the general Cronbach's α was 0.84 and the retest reliability was 0. 70 ( sub-scale: 0. 49-0. 86 ) . 6 common factors were extracted and the cumulative contribution was 75.41％. The score of the two scales was positively related(r=0.61, P<0.01). Conclusion The revised C-CIDS and C-SDSCA scales turn out to have good reliability and validity, and can be used as instruments to assess diabetes self-management efficacy and self-care activities of Chinese adult T1D patients.

Primary Sj?gren's syndrome(pSS)is a chronic inflammatory autoimmune disease involving a variety of exocrine glands.It is a common autoimmune disease in the department of rheumatology.However,the pathogenesis of pSS is still unclear,re-sulting in lack of treatment.While the international research on pSS is also increasing,we review the latest literature on the mecha-nism of Sj?gren's syndrome under different factors.In this paper,the process mechanism of Sj?gren's syndrome is summarized from the aspects of heredity,environment,autoimmune cells and autoantibodies.

Objective To assess the value of voiding urosonography (VUS) with SonoVue in evaluation of vesicoureteral reflux. Methods Thirty-six pediatric patients (72 pyeloureter units [PUUs]) suspected of vesicoureteral reflux underwent both VUS and fluoroscopic voiding cystourethrography (VCUG). The sensitivity of VUS and VCUG and their consistency in detecting vesicoureteral reflux as well as in grading vesicoureteral reflux were compared. Results Vesicoureteral reflux was detected in 26 of the 72 PUUs (36.1%) by VUS while in 21 PUUs (29.2%) by VCUG (P=0.347). The two modalities yielded the same results for 65 PUUs (κ=0.843), showing a very good consistency between them. VUS also detected post-urethral valve in 2 patients via transperineal scans. Conclusion VUS with Sonovue has at least comparable, if not better, sensitivity in detecting vesicoureteral reflux with VCUG, and therefore should serve as the primary screening and follow-up modality for vesicoureteral reflux. In addition, transperineal VUS can be helpful in evaluation of post-urethral lesions.

INTRODUCTIONIn the past several decades, declining incidences of nasopharyngeal carcinoma (NPC) have been observed in Chinese populations in Hong Kong, Taiwan, Los Angeles, and Singapore. A previous study indicated that the incidence of NPC in Sihui County, South China remained stable until 2002, but whether age, diagnosis period, and birth cohort affect the incidence of NPC remains unknown.

METHODSAge-standardized rates (ASRs) of NPC incidence based on the world standard population were examined in both males and females in Sihui County from 1987 to 2011. Joinpoint regression analysis was conducted to quantify the changes in incidence trends. A Poisson regression age-period-cohort model was used to assess the effects of age, diagnosis period, and birth cohort on the risk of NPC.

RESULTSThe ASRs of NPC incidence during the study period were 30.29/100,000 for males and 13.09/100,000 for females. The incidence of NPC remained stable at a non-significant average annual percent change of 0.2% for males and -1.6% for females throughout the entire period. A significantly increased estimated annual percent change of 6.8% (95% confidence interval, 0.1%-14.0%) was observed from 2003 to 2009 for males. The relative risk of NPC increased with advancing age up to 50-59 and decreased at ages >60 years. The period effect curves on NPC were nearly flat for males and females. The birth cohort effect curve for males showed an increase from the 1922 cohort to the 1957 cohort and a decrease thereafter. In females, there was an undulating increase in the relative risk from the 1922 cohort to the 1972 cohort.

CONCLUSIONSThe incidence trends for NPC remained generally stable in Sihui from 1987 to 2011, with an increase from 2003 to 2009. The relative risks of NPC increased in younger females.
