Objective To understand serological detection results of syphilis among hospitalized patients in a gen-eral hospital,and provide new ideas for further prevention and treatment of syphilis. Methods Clinical data of inpa-tients with abnormal serological detection results for syphilis in a hospital from January 2012 to December 2013 were analyzed. Results A total of 164442 patients were admitted to a hospital from January 2012 to December 2013, 112576 of whom were performed syphilis serological screening,2048 cases were with abnormal results of serologi-cal detection for syphilis. The abnormal serological detection results were mainly in patients of 31~ and 41~ years (39.06% ),followed by patients of 51~,61~ years (34.42% ),and≥71 years (15.63% );unemployed people (34.08% ),farmers(23.05% ),and retirees(19.19% )were the main population with abnormal results. The abnor-mal serological detection results distributed in all 36 departments,the main departments were departments of respir-atory medicine(9.86% ),gynaecology(7.13% ),and cardiovascular internal medicine(6.88% ). Non-marital sex is the main route of transmission(56.79% );the main syphilis serological detection results were both positive for Treponemapallidum particle agglutination (TPPA)assay and rapid plasma reagin (RPR)(46.14% ),as well as TPPA positive and RPR negative (43.31% ). 860 (41.99% )patients were with latent syphilis. Conclusion The current status of patients with abnormal serological detection results of syphilis is not optimistic, mainly concentrated in patients of 31-50 years. It is necessary to strengthen publicity and education on prevention and treatment of syphilis,implement syphilis prevention and treatment policy,intensity syphilis screening,so as to pre-vent the epidemic and spread of syphilis.

Objective To study the relationship between sensation seeking,personality characteristics and health-risk behaviors of medical freshmen.Methods Sensation Seeking Scale ( SSS),Eysenck Personality Questionnaire( EPQ),Adolescent Health-Risk Behaviors Questionnaire were applied in this survey to 384 freshmen from two medical colleges.Results ① The health risk behaviors were comnmon in the medical college freshmen (5.2％,48.2％ ),and the score of health risk behaviors had a significant difference between boys and girls,boys risk behaviors were much more than girls(P＜ 0.05 ).②The correlations between the risk behaviors (such as smoking,drinking,fighting,suicidal ideas,using internet too long,poor eating behavior,lack of physical exercise) and sensation seeking personality traits were strong.The health-risk behaviors were all correlated with extraversion(E)and neuroticism (N) significantly( 66.78 ± 10.29 vs 60.57 ± 9.09,t =2.54,P ＜ 0.01 ;7.11 ± 3.23 vs 5.33 ±2.89,t =2.81,P ＜ 0.05 ).③The results of logistic regression analysis showed that male mother' s high education level,sensation seeking,Eysenck' s P,N dimension were effective prediction factors of freshmen ' s health-risk behaviors.Conclusion Medical college freshmen who have higher levels of sensation seeking,Eysenck' s P,N dimension are more prone to health risk behaviors.

Objective To observe the final adult height (FAH) outcome and influencing factors in Turner′s Syndrome(TS) children treated with recombinant human growth hormone ( rhGH ).Methods Thirty TS children treated with rhGH were compared with 16 TS children without rhGH treatment and were followed up to achieve their FAH.Comparisons were made regarding predicted adult height (PAH),height standard deviation score for chronological age( HtSDScA ),height SDS for BA( HtSDSRA ),and growth velocity ( GV ) between rhGH treatment and without treatment groups and between the onset and by the end of rhGH treatment group.The factors determining FAH were also evaluated.Results FAH in rhGH treatment group was obviously improved as compared with untreatment group[ ( 149.5±6.3 vs 142.4±5.2) cm,P＜0.01 ].FAH in treatment group was positively correlated with height standard deviation score for chronological age ( Ht0 SDSCA ),Hto SDS for BA ( Hto SDSBA ),height age ( HA0 ) at preliminary diagnosis,and correlated with duration of rhGH therapy,duration of estrogen-free rhGH therapy,and PAH0SDS at preliminary diagnosis.Stepwise regression analysis indicated that duration of estrogen-free rhGH therapy and PAH0 SDS were the variables with the greatest identified influence on FAH (F =11.56 and F =86.91,P＜ 0.01 ).FAH in the 45,XO group was significantly different from the mosaicism group (45,XO/46,XX ) [ ( 147.2 ± 6.3 vs 153.3±6.4) cm,P =0.038].Conclusion rhGH treatment is efficacious in improving FAH of TS children,but a variability in the magnitude of the response to rhGH is recognized.Duration of estrogen-free rhGH therapy and PAH0SDS are the variables with the greatest identified influence on FAH,and karyotype may be one of the influence factors.rhGH treatment should be initiated as early as possible and sufficient course of estrogen-free rhGH therapy is needed to yield a satisfactory FAH.

The COI gene as DNA barcode was used to identify the Manis pentadactyla and its adulterants in order to provide a scientific basis for the molecular identification of M. pentadactyla. Genomic DNA was extracted from experimental samples using the DNA extraction kit. The COI genes were amplified using polymerase chain reaction (PCR) and sequenced bi-directionally. Obtained sequences were assembled using the CodonCode Aligner. The neighbor-joining (NJ) tree was constructed by MEGA 6.0. The results indicated that COI sequences were successfully amplified and NJ trees results indicated that M. pentadactyla and its adulterants can be easily identification. Therefore, the COI gene is an efficient barcode for identification of M. pentadactyla and its adulterants,which will provide a new technique for the market supervision.

Objective To assess the efficacy of gonadotropin-releasing hormone analogue(GnRHa)with or without recombinant human growth hormone(rhGH)treatment in Chinese short pubertal children with non-growth hormone deficiency.Methods Of 42 short pubertal children(14 males,28 females)without growth hormone deftcieney,the average age was(11.6±0.8)year.30 children were treated with slow release GnRHa with initial dose (100μg·kg-1·d-1,28d)and maintenance dose(60-80μg·kg-1·d-1,28d)labd rgGH with initial dose(0.15IU·kg-1·d-1)and maintenance dose(0.10-0.15IU·kg-1·d-1)for at least 1year.16 of them were still ongoing till the end of the second year.12 children were treated with GnRHa alone by initial dose(100μg·kg-1·d-1,28d)and maintenance dose (60-80μg·kg-1·d-1,28d),and 7 of them remained on it for 2 years.Dynamic changes including annual growth velocity(GV),bone age(BA)/chronologic age(CA)ratio,Tanner stage,height SDS for CA (HtSDSCA),height SDS for BA(HtSDSBA),and predicted adult height (PAHSDS)were observed.Results By the end of the first year tretment with combination therapy,the following parameters:GV,HtSDSCA,HtSDSBA,and PAHSDS all increased significantly(all P<0.05).Treatment with GnRHa alone did not yield significant changes in GV,HtSDSCA,HtSDSBA,and PAHSDS(all P>0.05).Changes in GV,HtSDSBA,and PAHSDS between these two groups were statistically significant(all P<0.05).By the end of the second year treatment,in the combination group,GV slowed from 6.7 to 5.5 cm/year(P<0.05).HtSDSCA,HtSDSBA,PAHSDS increased(all P<0.05).In the group with GnRHa treatment alone,GV slowed from 4.0 to 3.6 cm/year(P>0.05).HtSDSCA,HtSDSBA,PAHSDS increased(all P>0.05).Changes in GV,HtSDSCA,HtSDSBA,and PAHSDS between these 2 groups were statistically significant respectively(all P<0.05).Conclusion This combined treatment regimen significantly impreved the growth by increasing growth rate and delaying bone matumtion in pubertal chidren without growth hormone deficiency.Further study is needed to verify beneficial effects on the final height gain.

OBJECTIVETo evaluate the effects of periodontal treatment on the clinical response, systemic inflammatory parameters, and metabolic control of type 2 diabetes patients with moderate to severe periodontitis.

METHODSA total of 56 patients with mean clinical attachment level (CAL)>3 mm were included in the subgroup analysis. A repeated-measures ANOVA (group factor: treatment group and control group; time factor: initial visit, 1.5, 3, and 6 months) was used to analyze the probing depth (PD), CAL, bleeding on probing (BOP), high-sensitivity C-reactive protein (hsCRP), glycated hemoglobin (HbA1c), and fasting plasma glucose.

RESULTSSignificantly lower PD (F=62.898, P-0.000), CAL (F=51.263, P-0.000), BOP (F=75.164, P=0.000), hsCRP (F=6.391, P=0.010), HbA1c(F=4.536, P=0.011), and fasting plasma glucose level (F= 3.073, P=0.031) were observed after therapeutic periodontal improvement. The inter-group differences for PD (t=-2.050, P=0.045), BOP (t=-4.538, P=0.000), and hsCRP (t=-2.261, P=0.028) were statistically significant after therapy.

CONCLUSIONNon-surgical periodontal treatment can effectively improve periodontal status, circulating inflammatory status, and metabolic control of diabetic patients with moderate to severe periodontitis.

· AIM: To summarize the clinical features of Chinese primary congenital glaucoma and to investigate the discrepancies of the clinical features between the Chinese and Indian patients.congenital glaucoma patients were reviewed. The clinical features were summarized as several quantifiable clinical parameters and the severity of the disease was evaluated. Both the quantified clinical features and severity were statistically compared with those of the Indian patients, which were cited from the previous published articles.included in the study. In Chinese patients, sex ratio (male to female )was about 2:1, family history was presented in 3 patients (7.5%) and consanguinity was found in one patient (2.5%). The main symptoms and signs observed in Chinese patients spanned a wide spectrum of manifestations. The most frequent signs noted on the initial examination were enlarged eyeball (42.5%) and decreased visual acuity (35.0%). Compared with Indian patients, Chinese patients had a later onset, a delayed diagnosis, more severe corneal changes and more severe optic nerve damages (P＜0.01). The combined tabeculectomy and trabeculotomy operation was preferred by both Chinese and Indian doctors whereas a higher proportion of Indian patients received the combined operation (P＜0.01). The proportions of the severity grade were different between Chinese and Indian patients. Most Chinese patients were in the severe grade while most Indian patients were in the very severe grade (P＜0.01).patients were sporadic and non-consanguineous.Compared with Indian patients, Chinese patients had a relative later onset, a delayed diagnosis and treatment.More attempts are needed in Chinese PCG prevention and treatment.
