Pharmaceutical therapy,including anti-vascular endothelial growth factor treatment and intravitreal corticosteroids,is the most common treatment for branch retinal vein occlusion (BRVO) and its complications,however there are confusing ideas about the protocol,patient selection,timing and endpoint of this treatment.The disease is easy to relapse with these drugs therapy.Collateral vessel formation was found in patients receiving intravitreal injection of ranibizumab or triamcinolone for BRVO and secondary macular edema.The mechanism of collateral vessel formation has not been carefully investigated.In the past thrombolysis,arteriovenous fasciostomy and laser choroidal retinal vascular anastomosis were used to reconstruct the retinal circulation,but their rationality,effectiveness and safety need to be further were studied.In recent years,because of the key technology is still immature,the artificial vascular bypass surgery experiment is not yet practical,but provides us a new idea worth looking forward to for the treatment of BRVO.

OBJECTIVE: To evaluate the effect of intervention measures on perioperative preventative application of antibiotics. METHODS: 120 surgery patients in our hospital were collected and studied comparatively before (Jul.～Dec. of 2006) and after carrying out intervention measures (Jul.～Dec. of 2008). RESULTS: The rational utilization rate of antibiotic during perioperative period increased from 0% (before intervention) to 56.7 % (after intervention). Average admission day and average medication duration after operation both were shortened (P

Objective To isolate and clone novel O-superfamily conotoxin genes of Conus capitaneus Linnaeus collected from Hainan,which would provide the initial drug leads to investigate and develop Conus capitaneus conotoxins.Methods 3'-RACE(Rapid Amplification of cDNA Ends) was used for cloning the novel O-superfamily conotoxins.The specific amplified cDNA fragments were sequenced and analyzed,as well as the genetic diversity of the O-superfamily conotoxins.Results The full-length cDNA(CaHr91N) of a new O-superfamily conotoxin(CaHr91) was cloned and sequenced from Conus capitaneus Linnaeus.The novel conotoxin precursor CaHr91P with 77 amino acids(aa) encoded by the cDNA consists of three typical regions of signal with 21aa, pro-peptide with 22aa and mature peptide with 34aa.Predicted sequence of the toxin region CaHr91M is "ECREQSQGC TNTSPPCC SGLRC SGQSQGGVC ISN" with a common O-superfamily cysteine pattern C-C-CC-C-C.Percent identities between CaHr91P and other published homologue O-superfamily sequences were compared systematically,as well as research status on conopeptides from C.capitaneus.Conlusion The elucidated cDNA of the novel CaHr91P conotoxin will be the basis for a better understanding of its bioactivity and application,as well as finding more novel conotoxins from C.capitaneus.

Objective To investigate the clinical effect of gastric bypass operation on treating type 2diabetes,and analyze the management status.Methods Fifty-seven patients wiith type 2 diabetes treated by gastric bypass operation were divided by different body mass index(BMI) into 4 groups:group A( BMI ＜ 20kg/m2) with 8 cases,group B (20 kg/m2≤BMI ＜24 kg/m2) with 21 cases,group C (24 kg/m2≤BMI ＜27kg/m2) with 17 cases and group D (BMI ≥27 kg/m2) with 11 cases.The control of blood glucose and glycosylated hemoglobin,changes of diets and body weight,diabetes complications,adverse reactions after operation and postoperative management were followed up or reviewed.The clinical data were analyzed comprehensively.Results The cure rate of group C was the highest [ 70.6％( 12/17 ) ],while the cure rate of group A was the lowest (0).The overall cure rate was 43.9％(25/57) and the overall improvement rate was 28.1％(16/57).The overall efficient rate was 71.9％(41/57) and the overall inefficient rate was 28.1％(16/57).Apart from a few patients had malnutrition,amenorrhea,bad stomach,diarrhea and poor diet after leaving the hospital,other patients had no surgery complications and no patients died.There was no clinician to follow up and did education to these patients after operation.Conchusions Gastric bypass operation is safe and effective for obese and non-obese patients with type 2 diabetes.It is a new method to weat type 2diabetes at present,but the indications should be grasped and operation enlargement must he prevented.The management of teams of physicians,surgeons,dietitians,nurses should be established afler operation.

Objective:To investigate the correlation of the blood concentration of tacrolimus ( Tac) and serum cystatin C ( SCysC) and serum creatinine (Scr) in the patients with renal transplantation. Methods:Totally 84 cases of renal transplantation patients (67 male/17 female) treated with Tac were involved. The blood concentration of Tac, SCysC and Scr were monitored after the operation. Data results were categorized according to the postoperative time and the blood concentration. The correlations of Tac blood concentra-tion,SCysC and Scr were analyzed and compared by using Pearson correlation analysis. Results: The blood concentration of Tac was not significantly associated with SCysC and Scr in different postoperative time groups and different drug concentration groups ( P >0. 05). As the extension of time,the blood concentration of Tac showed a gradual declining trend, while SCysC and Scr levels de-creased first, and then increased gradually after two years of the operation. Conclusion:The blood concentration of Tac has no effect on the function evaluation of transplanted kidney by the biochemical indicators such as SCysC and Scr.

Objective: To understand the current situation and impacts of household factors on of unhealthy dietary habits among preschool children, and to provide reference for preventing the occurrence of unhealthy dietary habits of preschool children. Methods: By using stratified random cluster sampling method, the study selected 1 070 children aged 3-6 years in 7 kindergartens in Urumqi. Household general information , children’s dietary behavior and parenting environment was collected through parent questionnaire survey. Results: The prevalence rate of unhealthy dietary habits among preschool children was 32.71%. Multifactor Logistic regression analysis showed that the unhealthy dietary habits of preschool children were negatively correlated to the following factors, including age of children [β=-0.32, 95%CI=(0.62,0.86)] , gender[β=-0.33,95%CI=(0.53,0.97)], educational level of mothers [β=0.94, 95%CI=(1.79,3.68)] , type of fanmily [β=0.64, 95%CI=(1.414,2.522)] and the scores of social adaptation/selfcare and environmental atmosphere in the family nurturing environment [β=-0.07, 95%CI=(0.90,0.97); β=-0.21, 95%CI=(0.76,0.87)]. Conclusion The cultivation of the dietary habits should pay more attention on younger children and boys, and the enhancement of health education on the children’s eating behaviors among mothers with lower education background and the primary child caregivers in the stem family. Family nurturing environment should be actively improved, in order to prevent the occurrence of children’s unhealthy dietary habits.

Objective To explore the incidence and risk factors of common complications in PICC patients during chemotherapy in Xinjiang.Methods A prospective study was conducted.The patients with PICC were treated with PICC from April 2016 to April 2017 were followed up for 10 months. The incidence of PICC complication and the influencing factors were observed dynamically during chemotherapy.Results The incidence of PICC complication was 13.6%(42/208)during chemotherapy in Xinjiang patients.The incidence of PICC was higher in the third chemotherapy cycle and the incidences of the first and sixth chemotherapy cycles were lower. Age, valve type, number of punctures, maintenance time>7d, and living conditions were the influencing factors of PICC complications(P＜0.05). Conclusions The incidence of common complications of PICC in cancer patients during chemotherapy is high in Xinjiang region.The risk factors of complications include age＜18 years,number of open-end PICCs,increased number of punctures, maintenance time>7d and living conditions for rural areas. Clinical nurses should give personalized health guidance on the causes of complications in different patients to reduce the occurrence of complications of PICC,and improve the quality of PICC use.

Objective: To understand the situation of neglect and behavior problems of children aged 3-6 years in rural areas of Urumqi, Xinjiang, and to provide basis and reference for the prevention and treatment of child neglect. Methods: Stratified random cluster sampling was performed to select 1 326 children aged 3-6 years from 6 kindergartens in rural Urumqi. The “Chinese Rural Child Aged 3-6 Years Neglect Evaluation Norm” and “Conners Parent Symptom Questionnaire” were used. Results: The total neglect rate of rural children was 51.89%, and the rate of behavioral problems was 23.37%. Each dimensional score of neglect among children with behavioral problems was higher than those without behavior preblems, and the difference was statistically significant (t=2.77，4.05，2.95，2.44，3.01，2.71，P<0.05). Emotional neglect was correlated with all factors in behavioral preblems, except phychosomation fact (r=0.18，0.80，0.15，0.14，0.19，P<0.05). Neglect in educational was correlated with all factors in behavioral factors except anxiety and hyperactivity (r=0.06，0.05，0.62，0.08，P<0.05). Conclusion Neglect of children aged 3-6 years in rural areas of Urumqi is more prominent and behavioral problems are more common, which should be paid more attention by relevant departments and parents.

Background The introvitreal injection of triamcinolone acetonide (TA) before vitrectomy for retinal with choroidal detachment (RD/CD) can alleviate inflammatory response,but it easily lead to complications under the low intraocular pressure.The study on the efficiency and safety of subtenon injection of TA for treatment of RD/CD is lack.Objective This study was to evaluate the efficiency and safety of subtenant injection of TA with vitrectomy for treatment of RD/CD.Methods A retrospective study was adopted.The data of 22 eyes of 22patients who received subtenon injection of TA with vitrectomy for RD/CD were collected and analyzed in Affiliated Eye Hospital of Wenzhou Medical University from May 2010 to June 2014.TA of 40 mg in 0.4 ml was administered subtenantly 5 days before RD repair surgery.After initiating the treatment,the therapeutic effects on uvitis were analyzed.Intraocular pressure was monitored and CD height and range were determined by B type ultrasonography before injection and 5 days after injection respectively.In addition,blood glucose and blood pressure of the patients were evaluated.Results Ocular inflammation alleviated to some degree after TA injection in all 22 eyes.The mean intraocular pressure was (5.4±2.9) mmHg (1 mmHg =0.133 kPa) in pre-injection and (8.2±4.3) mmHg in postinjection,showing a significant difference between them (t =3.430,P ＜ 0.01).The mean maximum CD height was 5.2 (3.1,6.6)mm in pre-injection and 0.9 (0,3.8)mm in post-injection,with a significant difference between the before and after injection (Z=-4.198,P＜0.01).The mean CD range was 12 (10,12) clock before injection and 3(0,6) clock after injection,and no significant difference was found between before and after injection (all at P＞0.05) (Z=-4.124,P＜0.01).There were no statistically significant difference in the changes of blood glucose and blood pressure between before and after injection.The LogMAR visual acuities were 2.14±0.46,1.29±0.57 and 1.17±0.55 before injection and 1 month,3 months after injection,respectively,with a siginificant difference among them (F =22.060,P＜0.001).The retinal reattachment rate was 95.5 ％.Conclusions Subtenon injection of TA seems to be a good option for perisurgical management of RD/CD patients,which can alleviate uvitis,increase intraocular pressure,reduce CD height and CD range.
