BackgroundLaser peripheral iridotomy(LPI) can break the pupillary block,and is an effective method of treating acute primary angle closure (APAC).However,a part of APAC eyes may gradually develop a formation and extension of peripheral anterior synechia(PAS) and increased intraocular pressure(IOP) after LPI.ObjectiveTo investigate the relationship between appositional angle closure and darkroom provocative test(DRPT) in the fellow eyes with APAC after LPI.Methods Fellow eyes of APAC without PAS after LPI were studied.Ultrasounic biomicroscopy(UBM) were performed in darkness to observe whether appositional angle closure occurred and compare the relationship between the quadrants with appositional angle closure and the results of DRPT.Results Fifty-four patients were included in the study.Appositional angle closure was observed in at least one quadrant in 20(37.0％ ) of the 54 fellow eyes with APAC after LPI.Fifty-one patients were given DRPT and positive result in 9 patients( 17.6％ ).According to the quadrants with appositional angle closure,there were 5 patients with DRPT positive results in 46 patients with appositional angle closure 0 to 2 quadrants,and 4 patients with DRPT positive results in 5 patients with appositional angle closure 3 to 4 quadrants ( P =0.003 ).Bivariate correlation analysis indicated a positive correlation between the value of the increased IOP in DRPT and the number of quadrants with appositional angle closure in darkness( r =0.397,P =0.004).ConclusionsA certain proportional fellow eyes of APAC appeared appositional angle closure in darkness and DRPT positive result after LPI.The more the quadrants of appositional angle closure after LPI,the greater the likelihood of a positive DRPT.It suggests that the APAC fellow eyes and attack eyes with the same anatomical configuration still have the possibility of angle closure after LPI,and need follow-up and treatment for a long time.

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 study the effect of injection ganciclovir in infants with rotavirus disease.Methods According to age (6 months to 2 years) and typical clinical symptoms in combination with etiologic evidence of rotavirus, 76 patients within 2 days after onset were selected as study subjects. These young children were randomly assigned to two groups according to the hospitalized order.Treated group received intravenous administration of ganciclovir 5～10 mg/(kg?d) once daily for 3 days while control group didn′t receive any antivirus drugs. Rotavirus testing by ELISA on stool samples was performed for every patient on admission and the third day after treatment. Stool sample was collected to a clear box every day in patients with positive results until the reaction was negative.Results The total effective rate after treatment was 88.1% and 61.8% in treated group and the controll group, respectively. There was significant difference between these two groups(?2=20.42 P

Objective To explore the effect of Melatonin(MT) on CD4+CD25+ regulatory T cell (CD4+CD25+Tr)and airway inflammation in asthmatic rat.Methods Thirty-two SD rats were randomly divided into 4 groups,8 rats in each group.Asthmatic group:rats were immunized on day 1 and 7 by intraperitoneal inject of mixture of ovalbumin(OVA) and aluminumhydroxide.From day 14,the animals were allenged with aerosolized OVA for 20 min per day for 7 consecutive days.MT group:OVA-sensitized rats were injected intraperitoneally with 0.1 mg/kg MT 30 min before each OVA challenge.Dexamethasone group:OVA-sensitized rats were injected intraperitoneally with 0.5 mg/kg Dexamethasone 30 min before each OVA challenge.Control group:OVA for inhalation and MT for intraperitoneal injection was replaced with saline.After the last challenge,peripheral blood was stained to count the percentage of eosinophil(EOS).Then the rats were lavaged and total leukocytes counts in bronchoalveolar lavage fluid(BALF) were performed after staining with Wright-Giemsa staining.The EOS counts around the airway was counted after the histological section of lung staining with hematoxylin and eosin staining.The serum level of immunoglobulin E(IgE) was detected by immunoenhancement.The change of CD4+CD25+Tr was assessed with flow cytometry.SPSS 10.0 software was applied to analyze data. Results In asthmatic rats,the CD4+CD25+ Tr/ CD4+T cells ratio had significant negative relationship with the EOS counts around the airway and the total leukocytes counts in BALF (r=-0.73 P0.05).There was a significant decrease in the percentage of the eosinophils in peripheral blood,the eosinophil counts around the airway,the total leukocytes counts in BALF and the serum level of IgE in MT group compared with asthmatic group (Pa

Objective:To observe the changes in the anatomy of anterior segment before and after phacoemulsification for treatment of angle-closure glaucoma by Pentacam system,so as to assess the efficacy of phacoemulsification combined with artificial lens implantation(ALI)in treatment of early-and middle-stage angle-closure glaucoma.Methods:Forty-two patients with early-and middle-stage angle-closure glaucoma(44 eyes)were included in the present study.The central anterior chamber depth,anterior chamber volume and peripheral anterior chamber angle were examined by Pentacam system pre-operatively and 1 day,1 week and 3 months post operatively.Meanwhile,A ultrasound was used to examine the anterior chamber depth before and 3 months after operation.and the results were compared with those by Pentacam system.Results:Pentacam system could clearly demonstrate the 3-dimensional structures of the anterior eye segment before and after operation.The central anterior chamber depth,anterior chamber volume and anterior chamber angle were increased significantly after operation(P

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.

Objective To evaluate the treatment effect of hand reconstruction with bilateral multiple toe transplantation. Methods There are four schedules as follow applied in 102 cases: (1) bilateral second toes to thumb and index finger transplantation in 86 cases; (2) wrap-around flap to thumb and second toe on opposite side to index or middle finger transplantation in 11 cases; (3) wrap-around flap to thumb and bilateral second toes to index and middle fingers transplantation in 8 cases; (4) bilateral wrap-around flap to bilateral thumb and second toe to index finger transplantation in 1 case. Results All reconstructed finger survived in 102 cases except for partial wrap-around flap necrosis in one case and second toe in two cases. Sixty-two patients got more than one-year following up. Two points discrimination in reconstructed finger was between 8 to 14 mm in all cases. The reconstructed finger grew synchronously with toe among children. Thumb opposition function recovered in all cases except for one case. Donor site: no limp or hallux eversion observed in all cases. Conclusion There is less damage on foot and most hand function recovery using bilateral multiple toe transplantation to repair hand or multiple fingers defect.

Hepatic encephalopathy (HE) is a common and complex neuropsychiatric complication in patients with liver cirrhosis and has the features of high incidence, recurrence, and mortality rates, and it is also an important factor for the increased risk of hospitalization and rehospitalization. At present, there are still no effective drugs for HE. Recent studies have found that intestinal microecological changes are associated with the development, progression, and prognosis of HE, and the regulation of intestinal flora has a certain preventive effect on HE. This article summarizes the research on the association between intestinal microecology and HE in recent years and hopes to provide new ideas for clinical prevention and treatment of HE.
