Objective To evaluate the effect of medicial and surgical treatment for juvenile hyperthyroidism.Methods Ortapazole was administ rated separately in drug therapy group for 1.5-2 years.Bilateral subtotal thyroidectomy was done in surgical therapy group.Results In drug therapy group,effective rate was 60 percent in 6 months and 70 percent in one year.Recurrence rate was 40 percent after drug withdrawal in 2 years curative rate was 60 percent.In surgical therapy group,the average stay in hospital was 16 days.There was no nerve injury,parathyroidal hypofunction,thyroid crisis or hypothyroidism complications,with 100 percent curative rate after 2 years′ followup.Postoperative growth and development were normal.Conclusions Surgical treatment may be suitable for those who have no response to drug therapy,with recurrence after drug withdrawal,whose compression symptom was obvious,with moderate and severe hyperthyroidism or those who could not take medicine persistently.Bilateral subtotal thyroidectomy applied in juvenile hyperthyroidism could achieve quick and better recovery,and has no influence on the juvenile growth and development.

Objective To observe the time-dependent changes of astrocytes and microvessels in the ischemic core and surrounding areas.Methods Glial fibrillary acidic protein (GFAP)was measured by HE,and CD31 by immunohistochemistry as markers in post-mortem specimens from ten patients,who died of cerebral infarction.Results Each section of the infarcted brains was divided into four areas (the area 0-3).GFAP expressed a little in area 0 and 1,increased in a time-dependent manner in area 2 and 3;CD31 die not expressed in area 0,expressed a little in the area 1,and increased in area 2 and 3 continuously.Conclusions The proliferation of astrocytes and microvessels may play a significant role in the process of restoration after cerebral infarction.

To develop an analytic method for qualitative and quantitative analysis of dodecatetraenamides A, B in 42 samples of two official species of Asari Radix et Rhizoma( ARR) (37 samples of Asarum heterotropoides var. mandshuricum with different collection time and 5 samples of Asarum sieboldiivar. seoulense). The HPLC-IT-TOF-MS/MS methods for the qualitative and UPLC-PDA methods for the quantitative analysis were established. Dodecatetraenamides A, B were identified by comparing the retention time, UV absorption spectrum and quasi-molecular ion peak [ M + H]+ with the reference compound using HPLC-IT-TOF-MS/MS. The content of dodecatetraenamides A and B in ARR were determined by UPLC-PDA. The separation was successfully carried out on a ACQUITY UPLC BEH C18 (2.1 mm x 100 mm, 1.7 µm) column eluted with mobile phases of water (A) and acetonitrile (B) in gradient program (0-3 min, 35% B; 3-5 min, 35%-36% B; 5-6 min, 36%-43% B; 6 min-11 min 43% B; 11-12 min, 43%-100% B). The column temperature was 45 °C, and the detection wavelength was set at 254 nm. The flow rate was 0.6 mL · min(-1). On one level mass spectrometry scanning, the results showed that the quasi-molecular ion [M + H] + of both dodecatetraenamides A and B were m/z 248.20. The quantitative method with UPLC-PDA has made the baseline separation of the constituents, which were reported as mixtures in the most literatures. The average recovery of dodecatetraenamides A and B were 97.90% and 99.86%, the relative standard deviation were 0.4% and 1.1%, respectively. The contents of dodecatetraenamides A, B in all ARR samples was in the range of 0.11-3.89 and 0.24-6.65 mg · g(-1). Their contents reduced with the extension of storage time. Compared with the samples of 2013, the average content of the two constituents in the samples collected in year 2002-2003 reduced 34% and 36%, respectively (P < 0.05). Compared the A. sieboldii var. seoulense and A. heterotropoides var. mandshuricum with the same collective time and production area, the average contents of the two constituents in latter were up to (1.59 ± 0.75) mg · g(-1) and (2.90 ± 1.17) mg · g(-1), respectively, significantly higher than that in A. sieboldii var. seoulense (dodecatetraenamide A were (0.78 ± 0.52) mg · g(-1), dodecatetraenamide B were (1.69 ± 0.83) mg · g(-1)) (P < 0.05). The content of the dodecatetraenamide A in overground part was in the range of 0.11-0.33 mg · g(-1), dodecatetraenamide B was 0. 24-0.60 mg · g(-1), which were much lower than that of the underground part of ARR (dodecatetraenamide A was in the range of 0.73-3.89 mg · g(-1), dodecatetraenamide B was 2.11-6.24 mg · g(-1)). The method was certified to be simple, accurate and reliable and could be used for qualitative and quantitative analysis of dodecatetraenamide A and B in different species of ARR, also can be used for the comprehensive quality control of traditional Chinese medicine, Asari Radix et Rhizoma.

The purpose of this study was to observe the ultrastructure of human umbilical cord mesenchymal stem cells (hUCMSC). hUCMSC from full-term newborn umbilical cord were isolated and cultured by collagenase digestion, and then subcultured, amplification, and cell morphology was observed by microscopy. The immunophenotype and trilineage differentiation potential of hUCMSCs at passage 3 were analyzed. Transmission electron microscopy and scanning electron microscopy were used to observe the ultrastructure of hUCMSC. The results indicated that appearance of hUCMSC was spindle-shaped and polygonal, and nuclei were observed. hUCMSC expressed immunophenotype CD44, CD73, CD105, did not express CD34, CD45, CD31 and human leukocyte antigen HLA-DR. hUCMSC were capable of adipogenic, osteogenic, and cartilage differentiation; the short and thick microvilli processes were seen at the surface of hUCMSC by scanning electron microscope. Two different cell morphologies of hUCMSC were seen under transmission electron microscope, the one was a quiescent period in which a large and round or oval nucleus only one nucleolus were seen, cytoplasmic organelles were less; the other was in a relatively active period in which one or two nuclei in the same one cell were observed, the organelles were rich, structure was clear, expansion of the mitochondria was visible. It is concluded that the cells successfully isolated and cultured from umbilical cord, which possess biological characteristics of MSC and display two different states of ultrastructure.

Objective To investigate the clinical characteristics,diagnosis,treatment and prognosis of human swine streptococcosis occurred in some areas of Jiangsu Province from late summer to autumn since 1998.Methods The epidemiologic and clinical features of 42 cases were collected and analyzed.The bio- chemical features of strains isolated from patient's blood or cerebrospinal fluid(CSF) were tested,and the homogeneity were compared among 15 Streptococcus suisⅡ.Results All patients had acute infection toxe- mic symptoms such as chill,fever,headache and malaise etc.Toxic shock syndrome or meningitis syndrome were the major clinical manifestations.Forty two cases of human swine streptococosis were classified into 3 types:the rates of general,shock and meningitis type were 7.1% (3/42),38.1% (16/42) and 54.7%(23/42),respectively.Ten patients were died of shock type,32 were cured.Strain isolated from patients was identified as Streptococcus suisⅡby API-Strep,the biochemical reactional code was 0641473,and appraised result was 99.9%.There was highly homogeneity in the strains of Streptococcus suisⅡisolated from patients and sick pigs identified by genomic fingerprinting.Com- bined therapy of large doses of penicillin G and ceftriaxone was effective in these patients.Conclusions Human swine streptococosis is zoonosis caused by Streptococcus suisⅡand the clinical manifesta- tions are variable.In the cases of shock type,the onset of disease is stormy and the fatality rate is very high.While the prognosis of general and meningitis type is good and the majority of the cases are cured by effective antibiotic therapy.

Outbreaks of hand-foot-mouth disease (HFMD) have occurred many times and caused serious health burden in China since 2008.Application of modem information technology to prediction and early response can be helpful for efficient HFMD prevention and control.A seasonal auto-regressive integrated moving average (ARIMA) model for time series analysis was designed in this study.Eighty-four-month (from January 2009 to December 2015) retrospective data obtained from the Chinese Information System for Disease Prevention and Control were subjected to ARIMA modeling.The coefficient of determination (R2),normalized Bayesian Information Criterion (BIC) and Q-test P value were used to evaluate the goodness-of-fit of constructed models.Subsequently,the best-fitted ARIMA model was applied to predict the expected incidence of HFMD from January 2016 to December 2016.The best-fitted seasonal ARIMA model was identified as (1,0,1)(0,1,1)12,with the largest coefficient of determination (R2=0.743) and lowest normalized BIC (BIC=3.645) value.The residuals of the model also showed non-significant autocorrelations (PBox-Ljung (Q)=0.299).The predictions by the optimum ARIMA model adequately captured the pattern in the data and exhibited two peaks of activity over the forecast interval,including a major peak during April to June,and again a light peak for September to November.The ARIMA model proposed in this study can forecast HFMD incidence trend effectively,which could provide useful support for future HFMD prevention and control in the study area.Besides,further observations should be added continually into the modeling data set,and parameters of the models should be adjusted accordingly.

0.05 for all).Conclusions The allelic frequencies of LPL gene at Pvu Ⅱ locus in Hei Yi Zhuang were different from those in Han,but the genotypie frequencies in Hei Yi Zhuang were not different from those in Han.There was no significant correlation between the polymorphism of LPL gene at Pvu Ⅱ site and the serum lipid levels in two ethnic groups.

Abstract: Objective　To investigate the drug demand and related influencing factors of AIDS non-occupational post-exposure prophylaxis (nPEP) among men who have sex with men (MSM) in Wuhan, and to provide a scientific basis for the development of subsequent intervention policies for MSM. Methods　With the assistance of social organizations in Wuhan, MSM was recruited by the snowball method to carry out an online questionnaire survey to collect information on demographics, AIDS-related knowledge, high-risk behaviors, and the need for nPEP medication. The χ2 test and unconditional Logistic regression were used to analyze the related factors of the demand for nPEP medication. Results　A total of 308 valid subjects were included in this study, with predominantly 18-29 years old (78.57%, 242/308). The self-reported sexual orientation was mainly homosexuality (82.47%, 254/308), and the awareness rate of AIDS knowledge was high (89.29%, 275/308). Among the survey respondents, 35.06% (108/308) did not know the situation of HIV infection among MSM population in Wuhan; 55.19% (170/308) had two or more same-sex sexual partners in the last six months; 90.91% (280/308) had heard of nPEP before participating in this survey. After passing nPEP and informing the protective effect of nPEP, 59.42% (183/308) of them needed nPEP. After HIV exposure, 73.38% (226/308) were willing to spend money to buy nPEP drugs, and 88.64% (273/308) were willing to take nPEP drugs because of the known side effects. Logistic regression analysis showed that in the last six months, the needs for taking nPEP medication in those who had 2 or more same-sex sexual partners (OR=2.121, 95%CI: 1.329-3.386) and who had received peer education (OR=1.740, 95%CI: 1.088-2.781) were higher than those of those who had a same-sex sexual partner in the last six months and who had not received peer education. Conclusions　The MSM population in Wuhan has a great demand for nPEP drugs, and peer education is an important way to carry out nPEP publicity and promotion. At the same time, we should continue to strengthen warning publicity and education and behavioral intervention to reduce MSM risky sexual behaviors and reduce new HIV infections.
