Objective To assess the relationship between Helicobacter pylori(Hp) infection and idiopathic thrombocytopenic purpura (ITP) in children.Methods All the published literatures of relationship between Hp infection and childhood ITP were searched by computer and manual search from 2000 to 2010 in the CNKI database,WANFANG database,Chongqing Vip database and Pubmed database.A comprehensive analysis of case control studies were used by Meta analysis and calculated the value of integrated OR and 95%CI.Results Thirty-five pertinent literatures were collected.After literature which study methods not fit the request were ruled out,there were 8 effective documents in all,including 6 Chinese literatures,and 2 English literatures.Meta analysis of OR value and 95%CI were 1.90(1.44-2.50),and Z value of combined effect of tests was 4.56 (P=0.000 01) in ITP group and control group.Meta analysis results of OR value and 95%CI were 0.74(0.49-1.13),and Z value of combined effect of the test was 1.38 (P=0.17) in acute ITP and chronic ITP group.Conclusions Hp infection is closely related with the incidence of ITP,but has nothing to do with the type of ITP.

Objective To evaluate the clinical efficacy of acupuncture at Baihui (GV 20) and Shenting (GV 24) in treating post-stroke cognitive impairment (PSCI) by using the systematic review method.Method Via computer, Chinese Journal Full-text Database (CJFD), Wanfang, China Biology Medicine disc (CBMdisc), Chinese Science and Technology Periodical Database, PubMed, Foreign Evidence-Based Medicine (FEMB), the Cochrane Library were retrieved.Chinese Acupuncture and Moxibustion andShanghai Journal of Acupuncture-moxibustion were manually retrieved. Randomized controlled trials published before Jan 31st of 2013 on acupuncture at Baihui (GV 20) and Shenting (GV 24) in treating PSCI, both in Chinese and English, were collected. The required data were extracted, then were evaluated according to the criteria of Cochrane systematic review and underwent meta-analysis by using RevMan 5.0.Result Twenty-two clinical trials were finally recruited, including 1637 subjects. The meta-analysis showed that acupuncture at acupoints including Baihui (GV 20) and Shenting (GV 24) produced a more significant rehabilitation result compared to single rehabilitation training or medication. The comparison of Mini-Mental State Examination (MMSE) score showed: [WMD=3.37, 95％CI (1.70, 5.05),P<0.00001]; the comparison of P300 latency: [WMD=1.22, 95％CI (0.84, 1.59),P<0.00001]. Severe adverse reactions were not discovered. Conclusion Acupuncture at Baihui (GV 20) and Shenting (GV 24) can effectively improve the cognitive function of PSCI patients. However, the diagnostic criteria and evaluation indexes are expected to be unified and standardized, and the clinical trials on acupuncture intervening PSCI are required to be further improved methodologically.

Objective To explore the hurt of susceptibility organs and critical orgens followed by rotavirus (RV) infection of whole body in newborn mouse.Methods RV strain was derived from the stool samples of patients with RV diarrhea and was proved to be long type by methods of ELISA and polyacrylamide gel electrophoresis (PAGE). RV was inoculated by the pathways of taking orally and injected to abdominal cavities,respectively. The pathological changes of the newborn mouse model infected with human natural RV by light microscope and electron microscope. The gene probe was marked by digoxin.The direct prove of RV infection in these organs was got by the detection of in situ PCR. Results Pathological changes were found in the small intestinal villus,lamina propria of the stomach and the heart cells of the mice taken RV orally.The mice with intraabdominal RV injection showed pathological changes of the cells in the small intestinal villus,liver and kidneys observed by electron microscope.Shortened small intestinal villus,nuclear membrane disorganization,massive vacuolization,mitochondrial swelling and rough endoplasmic reticulum dilation were observed in the cells of small intestinal.In the liver of the mice,marked mitochondrial swelling and agglutination,cell nucleus pyknosis or collapse,presence of numerous lipid droplets and vacuoles were found in the li-ver cells,with lymphocyte and plasmacyte infiltration.Obvious dilatation and shedding of the microvillus were found in cholangioles.The mitochondria of the proximal convoluted renal tubule showed mild swelling,but the cells in the heart and lung did not display obvious changes.Conclusion RV can damage lots of extra intestinal organs of the newborn mice if RV diffuses to the whole body of the mice.

Objective To study local people's habits and customs concerning the prevention of dental fluorosis in an indoor coal-combustion-type fluorosis area of Zhaotong city Yunnan province, and to provide reference value for monitoring and control of the disease. Methods In 2008, 600 people of a 12-year-old group (400 people) and a 35 - 44-year-old group(200 people) were examined for dental fluorosis and oral health status in an indoor coal-combustion-type fluorosis area of Zhaotong. A questionnaire survey of 120 students and 60 adults was carried out on their habits and customs, stove changing status, knowledge of prevention of dental fluorosis, social psychology status, oral health behavior and their need for medical treatment. Results The total prevalence of dental fluorosis was 91.0% (546/600), dental fluorosis index was 2.58. The total prevalence of dental fluorosis of 12-year-old group was 86.5%(346/400), and dental fluorosis index was 2.12. The total prevalence of dental fluorosis of rural student was 90.5% (181/200), which was obviously higher in the rural group than the urban group [82.5% (165/200), χ2 = 5.48, P < 0.05]. The total prevalence of dental fluorosis of 35-44-year-old group was 100% (200/200), which was obviously higher than that of the 12-year-old group(χ2 = 29.67, P < 0.01). The rates of using coal, baking of food, changing stoves were 66.7% (60/90), 14.4% (13/90),57.8% (52/90), respectively, and these values of the urban were much lower than those of the rural[95.6%(86/90) ,31.1%(28/90) ,76.7%(69/90),χ2 = 24.51,7.11,7.29, all P < 0.01]. Only 23.3% (42/180) of people surveied had the knowledge of prevention of dental fluorosis, and the rate in the adult group[56.7% (34/60)]was higher than that of the student group [6.7% (8/120), χ2 = 55.9, P < 0.01]. The same rate in the urban student group was 0(0/60), and the rural student group was 13.3%(8/60), there was a significant difference between them(χ2 = 5.66, P < 0.05). Seventy-three point nine per cent( 133/180) of these people thought dental fluorosis had significant effect on their life, 91.1%(164/180) of these 'people wished to be treated. Eighty-four point four per cent( 152/180) of the people had a habit of toothbrushing,and 50.7% (77/152) of these people were still using toothpaste containing fluorine. Conclusions Zhaotong is a serious indoor coal-combustion-type fluorosis area. Enhancing health education to local people especially to students, and changing people's unhealthy habits and customs are keies to control the prevalence of indoor coal-combustion-type dental fluorosis.

Objective To respectively analyze the patterns and possible predictors of recurrent strokes among patients with initial ischemic stroke.Methods Three hundred and sixty-one patients with recurrent strokes (acute ischemic stroke or intracerebral hemorrhage) after initial ischemic strokes were collected from Jan 2004 to Dec 2009.The data about conventional risk factors such as smoking,heavy alcohol drinking,hypertension,diabetes,hyperlipidemia,heart diseases,head trauma,migraine,family history of cardiovascular disease,and the use of preventive medications were collected and analyzed among patients with different types of recurrent strokes.Results Patients (n =361) were divided into ischemic stroke group (n =321) and hemorrhagic stroke group (n =40) according to the recurrent stroke type.The ischemic stroke group was further divided into the anterior circulation stroke subgroup (n =234),the posterior circulation stroke subgroup (n =75) and watershed cerebral infarction or multiple infarction subgroup (n =12).Multivariate logistic regression analysis revealed that older age at initial stroke onset (OR =1.036,95 ％ CI 1.006-1.067,P =0.02) and hyperlipidemia (OR =2.253,95 ％ CI 1.092-4.647,P =0.028) were both the independent risk factors for the recurrent ischemic stroke.Comparing the subgroups,multivariate logistic regression analysis showed that atrial fibrillation (OR =4.217,95％ CI 1.489-11.942,P =0.007) was the independent risk factor for the recurrent ischemic stroke in the posterior circulation territory.Conclusion Aging and hyperlipidemia are possible predictors of recurrent ischemic stroke after the initial ischemic stroke which would be useful for individualized secondary prevention of stroke.

OBJECTIVETo observe differences of therapeutic effects among acupuncture bloodletting, penicillin and acupuncture bloodletting combined with penicillin for children acute tonsillitis and providea better treatment method in cli nic.

METHODSSeventy-five mild cases were selected into section of mild symptoms while seventy-five severe cases were selected into section of severe symptoms. Cases in the two sections then were divided into, an acupuncture bloodletting group, a penicillin group and a comprehensive group by random digital table method separately, 25 cases in each one. Qu-chi (LI 11), Hegu (LI 4), Dazhui (GV 14), Shaoshang (LU 11) and Erjian (EX 11) were selected in the acupuncture bloodletting group, intravenous injection of penicillin sodium was applied in the penicillin group and acupuncture bloodletting combined with penicillin was applied in the comprehensive group. Efficacy assessment was conducted after 3 days in the section of mild symptoms and after 5 days in the section of severe symptoms.

RESULTSFor the section of mild symptoms, the total effective rate was 96.0% (24/25) in the comprehensive group and 92.0% (23/25) in the acupuncture bloodletting group, which were both superior to 68. 0% (17/25) in the penicillin group (P<0.05), but no statistical significance was seen between the comprehensive group and acupuncture bloodletting group (P>0.05). For the section of severe symptoms, the total effective rate was 96.0% (24/25) in the comprehensive group, which was obviously superior to 60.0% (15/25) in the acupuncture bloodletting group (P<0.01) and 68.0% (17/25) in the penicillin group (P<0. 05), and no statistical significance was seen between the acupuncture bloodletting group and penicillin group (P>0.05).

CONCLUSIONThe efficacy of acupuncture bloodletting combined with penicillin is little different from that of acupuncture bloodletting for treatment of children acute tonsillitis with mild accompanied symptoms, which were both superior to intravenous injection of penicillin sodium. For severe accompanied symptoms, the efficacy of acupuncture bloodletting combined with penicillin is obviously superior to acupuncture bloodletting and penicillin.

OBJECTIVETo observe the effect of electro-acupuncture (EA) treatment on the oocyte quality in polycystic ovarian syndrome (PCOS) patients undergoing in vitro fertilization-embryo transfer (IVF-ET).

METHODSTotally 217 PCOS patients undergoing IVF-ET were assigned to two groups by random digit table, the EA group (119 cases) and the control group (98 cases). All patients received long program ovarian hyperstimulation with gonadotropin-releasing hormone agonist. Patients in the EA group received EA treatment in the process of controlled ovarian hyperstimulation till the oocyte retrieval day. The position relation of the spindle to the polocyte, the number of retrieved oocytes, the fertilization rate,the cleavage rate,the high quality embryo rate, the ovarian hyperstimulation syndrome (OHSS) incidence rate, the clinical pregnancy rate, the early abortion rate, the gonadotropins (Gn) dose and time, levels of estradiol (E2), progesterone (P), and luteinizing hormone (LH) on the day of human chorionic gonadotropin (HCG) were observed between the two groups.

RESULTSThe ratio of oocytes in which the meiotic spindle deviation angle was < 60 degrees to the all oocytes was obviously higher in the EA group than in the control group (P < 0.05). The oocytes in which the meiotic spindle deviation angle was < 60 degrees was positively related to level of E2 on the HCG day and the high quality embryo rate (r = 0.19,P < 0.01). Compared with the control group, the high quality embryo rate increased significantly (P < 0.05), the dose and days of Gn decreased significantly (P < 0.05) in the EA group. The clinical pregnancy rate was improved by 8.36%.

CONCLUSIONSThe spindle was positively correlated with the oocyte quality. EA could improve the quality of oocytes and the clinical pregnancy rate in PCOS patients undergoing IVF-ET.
