ObjectiveTo investigate the clinical efficacy of acupuncture in treating Tourette's syndrome.MethodEighty patients were allocated, using a random number table, to a treatment group of 40 cases and a control group of 40 cases. The treatment group received acupuncture and the control group, Western drug treatment.ResultThe YGTSS score decreased significantly in the two groups of patients after treatment(P<0.01). After treatment, the range of decrease in the YGTSS tic score was larger in the treatment group than in the control group; there was a statistically significant difference (P<0.05). The total efficacy rate was higher in the treatment group than in the control group (P<0.05). The incidences of adverse reactions were significantly lower in the treatment group than in the control group.ConclusionThe effect and safety of treatment for Tourette's syndrome are higher in the treatment group than in the control group.

We identified the routes of infection and evaluate the effect of disinfection on the field of an outbreak of an-thrax in a village of Wengan County ,Guizhou ,China ,thus trying to provide with basis for the implementation of policies for pre-vention and control of anthrax .The authors gathered the cases information by searching and interviewing the targeted persons house by house ,and reviewed the medical records in hospitals .The samples including patient’s discharging fluid ,residues of died horse ,and soil from the places where the villagers dismembered horse were gathered and cultured for Bacillus anthracis . The technique of multiple-locus variable-number tandem repeat analysis (MLVA-8) was applied for revealing the genetic rela-tionships among those isolated Bacillus anthracis strains .Five cases of cutaneous anthrax occurred in the outbreak and the total attack rate was 7 .58% (5/66) among those contactors evolved in the activity of carrying ,dismembering ,washing ,chopping and eating the died horse .The attack rate was 100% (3/3) for those who carried ,dismembered ,washed ,chopped and ate that horse ,100% (1/1) for those who carried ,dismembered and ate ,and 7 .14% (1/14) for those who washed ,chopped and ate . The 25% (1/4) of the samples of discharging fluid from the cases with cutaneous anthrax were positive .After disinfection , 15 .38% (4/26) of the soil samples retained positive .The genetic similarity was 100% among the 5 isolate strains .The results suggested that the outbreak of anthrax in villagers occurred through the activities of carrying ,dismembering ,washing and chop-ping the died horse .Strengthening the risk communication and disinfection of the dismemberment places should be the crucial strategies to prevent and control anthrax epidemics in Guizhou in the future .

Objective:To investigate the effect of lithium chloride (LiCl) on the gap junctional intercellular communication (GJIC) in human Tenon capsule fibroblasts (HTFs) and its underlying mechanism.Methods:The Tenon capsule tissue of a patient who underwent strabismus surgery in Dezhou People's Hospital in April 2019 was collected and cut into tissue blocks of dimensions 1 mm×1 mm×1 mm.Primary culture and subculture were carried out, and the 4th-generation HTFs were taken for experiment.HTFs were divided into the control group and LiCl treatment group and were cultured with cell medium without or with 80 mmol/L LiCl for another 48 hours according to grouping.The cell scratch and dye labeling technique were used to label the coupling index and evaluate the GJIC function.The expression and localization of Cx43 in HTFs were detected by immunofluorescence staining.The expression levels of Cx43 mRNA and protein were detected by real-time fluorescence quantitative PCR and Western blot, respectively.The study protocol was approved by an Ethics Committee of Dezhou People's Hospital (No.2019-023). Written informed consent was obtained from the subject.Results:The cultured spindle-shaped HTFs grew adhering to the wall showing radial monolayer or vortexlike, and the cytoplasm was vimentin positive.Results of dye tracer experiment of cell scratch showed that the cell coupling index of LiCl treatment group was 9.04±0.53, which was significantly higher than 4.94±0.39 of the control group ( t=-18.79, P<0.01). Immunofluorescence staining showed that the Cx43 fluorescence was dotted in the cell membrane between adjacent cells in the control group, and Cx43 staining was obviously enhanced in the LiCl treatment group.The results of real-time fluorescence quantitative PCR showed that with relative expression level of Cx43 mRNA in the control group set to 1, the relative expression level of Cx43 in the LiCl treatment group was significantly increased to 1.97±0.23, showing a statistical significance between them ( t=-14.426, P<0.01). Western blot showed that the relative expression level of Cx43 protein was 0.871±0.057 in the LiCl treatment group, which was significantly higher than 0.446±0.028 in the control group ( t=-11.682, P<0.01). Conclusions:LiCl can enhance the GJIC function between HTFs by upregulating the expression levels of Cx43 mRNA and protein, suggesting that the enhanced GJIC function by LiCl may be one of the mechanisms of its inhibition on HTFs proliferation.

Objective This study was to evaluate the effects of prevention and control regarding programs on typhoid fever and paratyphoid fever,in Guizhou province,from 2007 to 2012, to provide evidence for the improvement of related programs. Methods Data on typhoid fever and paratyphoid including information on epidemics,individual,cases,measures for prevention and control programs taken and relative government documents were collected and analyzed in Guizhou province,from 2007 to 2012. Information related to the average annual incidence,nature of outbreaks, time span before confirmed diagnosis was made,unit which carried the case report,proportion of laboratory confirmed diagnosed cases and case-management were compared between 2007-2009 and 2010-2012 descriptively while chi-square test with Excelland EpiInfo software were used for data analysis. Results In the period of 2007-2009,a total of 5 978 typhoid fever and paratyphoid fever cases were reported in Guizhou province with the average yearly incidence as 5.29/100 000. In the period of 2010-2012,2 765 cases were reported with the average yearly incidence as 2.57/100 000. When compared to the former,data from the latter period showed that the average yearly incidence had declined 51.31% in all the prefectures. There were still some outbreaks appeared but the total number of cases involved reduced 87.50%. The time span before the confirmation of diagnosis became shorter but the difference was not statistically significant (χ 2=0.08,P=0.99). Number of cases reported by hospitals at county or above had 11.51% of increase while those cases reported at the township hospitals or below decreased for 61.47%. The proportion of laboratory diagnosed cases increased 23.63%. Rates of timeliness on cards being filled in,inputted and audited showed increase of 8.44%,6.76%and 2.40%respectively. Conclusion Successful measures for prevention and control on typhoid fever and paratyphoid fever had been remarkably taken in Guizhou province,but the potential risk of outbreaks still existed in some areas,suggesting that health education and surveillance programs including laboratory diagnosis,should be strengthened.

OBJECTIVETo analyze causes of growing hepatitis E (HE) cases reported in Guizhou province, and probe into existing problems faced by medical institutions in diagnosis of clinical and laboratory-confirmed cases, for the purpose of improving the quality of HE surveillance system.

METHODSSix hospitals reporting greater HE cases from 2007 to 2011 were pinpointed, whose reported cases rose suddenly in 2011. Such cases were investigated by means of impatient medical record review, results of laboratory test and clinician interview.

RESULTS136 of the 354 reported HE cases investigated were found compliant with the diagnostic criteria of HE with an accordance rate of 38.42%. Difference of the HE diagnostic accordance rate among individual years, hospitals and reporting departments was statistically significant. Such rate of hospital reports was found to be the lowest in 2011, ranging from 0 to 18.18% respectively; HE cases reported by non-infectious departments accounted for 61.30% of total cases reported, with its accordance rate considerably below the infectious departments (8.29%). HE positive cases and HE positive rate in 2011 were significantly higher than that of preceding years.

CONCLUSIONSuch increase of reported HE cases in 2011 in the province was mostly attributable to more HE laboratory tests made by the hospitals, yet the accordance rates were lower than satisfactory. In this regard, the medical institutions in question were advised to enhance their competency training for HE diagnosis and case report quality.
