To investigate the advantage of using the medical sodium hyaluronate gel undergo goniosynechialysis, and to compare the difference of the viscoelastic agent and perfusion fluid by clinical control study.
●METHODS:Totally 103 cases (103 eyes) patients who had angle- closure glaucoma (ACG) with cataract all in Beijing Tongren Hospital affiliated to Capital Medical University, from September 2012 to February 2013. All the patients had primary glaucoma or recurrence ACG with cataract. Their intraocular pressure (lOP) could be controlled in normal value using one or two anti -glaucoma medications. We divided all the patients into two groups by chance. Experimental group had 53 cases (50 eyes), and control group had 50 cases (53 eyes). Two groups all had been performed phacoemulsification combined with goniosynechialysis by the same experiential operator. But experimental group did goniosynechialysis using the medical sodium hyaluronate gel, control group did goniosynechialysis using perfusion fluid. We observed the change of lOP, central anterior chamber depth and anterior chamber structure of two groups in postoperative 1mo.
●RESULTS: SPSS19. 0 statistics software was utilized to analyze the data, This study selected one- side test α =0. 05, adopted paired t - test or two- sample t - test. We obtained that experimental group lOP decreased 12. 42 ± 0. 04mmHg, anterior chamber depth increased 1. 276 ± 0. 201mm; that control group lOP decreased 6. 56 ± 0. 08mmHg, anterior chamber depth increased 0. 852 ± 0. 132mm. And experimental group anterior chamber angle opened more widely than the other group, the comparison had statistical significance (P<0. 05).
●CONCLUSlON: ln phacoemulsification combine with goniosynechialysis,use medical sodium hyaluronate gel do goniosynechialysis can more effectively decrease lOP. This because the medical sodium hyaluronate gel has high glutinousness, it can separate angle of anterior chamber and controlling lOP effectively.

Background Erythropoietin (EPO) was proved to be express in hematopoietic tissue and nervous system and play the effects of stimulating blood cell production and protecting nervous tissue.Researches showed that EPO is expressed in the embryon brain of animal.However,whether EPO exist in nervous-derived retina and its action on retina with the development is concerned. Objective This research was to investigate the expression of EPO during the embryonic development period of rat retina and explore the role of EPO in retina development process.Methods Clean Wistar rats with pregnancy for 12 days,16 days and 20 days were collected,and the embryonic 12-day rats (E12 d,5 rats),embryonic 16-day rats (E16 d,5 rats) and embryonic 20-day rats ( E20 d,5 rats) were obtained by caesarean operation,and 5 12-month W istar rats were used as controls.The rats were sacrificed by cervical dislocation and the retinal sections were prepared in the different-embryo-phase (12 d,16 d,20d) and growth phase.The expression of EPO protein and mRNA in rat retina was detected by immunohistochemistry and reverse transcription-polymerase chain reaction (RT-PCR),respectively.The feed and use of the animals followed the Regulation for the Administration of Affair Concerning Experimental Animals by State Science and Technology Commission.Results EPO was positively expressed in the cytoplasm and nuclei in the neuroepithelial layer and pigment epithelium of every-embryo-phase rats but only in retinal ganglion cell layer in 12-month-old rats.The gray scale values of EPO expression in retina were 105.55±10.35,99.35± 8.71,83.27± 7.84and 30.30± 3.80 in E12 d rats,E16 d rats,E20 d rats and 12-month-old rats respectively with a statistically significant difference (F=76.13,P＜0.01 ).RT-PCR revealed that the relative values of EPO mRNA expression in retina were 0.876±0.10,0.861 ±0.09 and 0.256±0.03 in E16 d rats,E20 d rats and 12-month-old rats respectively,presenting a elevated value in embryonic rats compared with adult rats ( P =0.00).Gel imaging deletion showed that the A value of EPO amplification products was highest in E16 d rats and lowest in adult rats.Conclusions The expression of EPO appears a high to low fashion during the embryonic development of Wistar rats,which is closely associated with the developing procedure of retina.

· AIM: To explore the relationship between the expression of Fas/FasL and the apoptosis in retinal ischemia/reperfusion injury of rats, as well as the therapeutic effects of basic fibroblast growth factor (bFGF)on the ischemic retina.injury were made by transiently elevating introcular pressure. A total of 28 rats were divided into Normal Group and Operative Group. The latter were subdivided into 1, 6, 12, 24, 48 and 72h after reperfusion, in which the left eyes of the rats were in the ischemia/reperfusion groups and the right ones were in the treatment groups (bFGF intracameral injection). Apoptosis was assessed by the terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick-end labelling (TUNEL) method, and theexpression of Fas/FasL ligand was studied by strept avidin-biotin complex (SABC) immunohistochemistry.mai rats' retinae, but there were a significant number of TUNEL positive cells in 6-24h after transient ischemia followed by a decrease at 48h. The number of TUNEL positive cells reached a maximum at 24h after ischemia.The expression of Fas gradually increased as early as at 6h, reached a peak at 24h, then decreased at 48h. Similarly, the expression of Fas ligand was at peak in 24-48h in GCL and INL of retina. bFGF ministered before reperfusion inhibited apoptotsis and ameliorated the tissue damage. It also diminished Fas and FasL expression in ischemic/reperfused retina.siently elevated IOP induced apoptosis of cells in the retina. Fas/FasL may have an important role in the early events of the apoptotic pathways. bFGF can rescue RGCs from retinal ischemia/reperfusion injury through down-regulation of Fas and Fas ligand expression and may represent an important mechanism for therapeutic neuroprotection.

Objective To evaluate the safety to perform 23G vitrectomy with scleral incisions at 5.0 mm behind the limbus.Methods This is a prospective uncontrolled case study.The data of 140 consecutive primary 23G vitrectomy patients (145 eyes) were enrolled in this study.There were 56 males (59 eyes) and 84 females (86 eyes),with the mean age of (56.34 ± 9.98) years and axial length of (23.99± 2.57) mm.There were 139 phakic eye and 6 aphakic eyes.All the eyes received 23G pars plana vitrectomy with scleral incisions at 5.0 mm behind the limbus.To measure the normal Chinese adult parameters of anteroposterior axis of the eyeball,lens thickness and scleral distances from the limbus to the plane passing through the lens posterior apex,the head CT scans of 105 patients without eye diseases in our hospital were studied during the same period of time for these vitrectomy surgeries.Pearson correlation analysis was used to analyze the relationship between age,anteroposterior axis of eyeball,lens thickness and scleral distances from the limbus to the plane passing through the lens posterior apex.Results Surgical related complications included retinal tears close to the scleral incision sites (3/145 eyes,2.1％) and lens injury (3/121 eyes,2.5％).No other surgical complications occurred,such as retinal hemorrhage,supra-choroidal expulsive hemorrhage and iatrogenic retinal detachment.Based on CT images,the average scleral distance from limbus to the plane passing through the lens posterior apex,anteroposterior axis of eyeball and lens thickness was (6.72± 0.81),(24.39± 0.97),(4.22 ± 0.47) mm,respectively.The results of Pearson correlation analysis showed that age and lens thickness had statistically significant correlation (r=0.328 9,P=0.000 6).Conclusion Primary 23G pars plana vitrectomy with incisions at 5.0 mm posterior to the limbus is safe.

OBJECTIVETo explore the clinical application value of Provider-Initiated HIV Testing and Counseling (PITC) by analyzing the positive rate of HIV tests for people in need of PITC and that of routine HIV tests.

METHODSWe retrospectively analyzed the demographic and epidemiologic data about the patients seeking PITC services or undergoing routine HIV tests in Nanjing Drum Tower Hospital between January and December 2013.

RESULTSThe positive rate of initial HIV screening was 1.98% in the PITC group and 0.24% in the routine test group, while that of confirmed HIV was 0. 40% in the former and 0.07% in the latter, both with statistically significant differences between the two groups (P < 0.01). The positive rate of HIV was markedly higher in males than in females, particularly in the PITC group.

CONCLUSIONPITC has a high clinical value in HIV detection for targeted subjects and therefore deserves general application in dermatology.

The aim of this research is to refine the protocol of purification of SA and identify the character of SA. By utilizing the cold-denaturing method, most of other kinds of protein were screened out and SA was purified from the fermentation broth of L-183 by using the refined affinity chromatography method. The rate of recollection was checked to be 75%～85%. By identification, it is indicated that the molecular weight of self-made SA was 74.5kD, the biotin-combining number 3.2, the activity 11.2u/mg, the pI around 7.4. So, the essential characters of SA are same as described by documents.

OBJECTIVETo assess the efficacy and safety of Wuji Powder (WP) and a small dose aripiprazole in treatment of antipsychotic drug-induced phlegm dampness type amenorrhea.

METHODSSeventy female schizophrenic patients with antipsychotic drug-induced galactorrhea-amenorrhea syndrome (GAS) were recruited and randomly assigned to the treatment group and the control group, 35 in each group. All patients received antipsychotic drug therapy. Patients in the treatment group additionally took WP, while those in the control group took aripiprazole (at the daily dose of 5 mg, once daily). The therapeutic course for all was 4 weeks. Prolactin levels and obesity indices[body weight, waist aircumstance, body mass index (BMI) and waist-hit ratio (WHR)] were determined before and after treatment. The efficacy was evaluated.

RESULTSThe treatment course was completed in 95.71% of patients. The total effective rate of the 33 patients of the treatment group was 93.94% (31/33), while it was 91.18% (31/34) in the 34 patients of the control group. There was no difference in the total effective rate between the two groups (P > 0.05). Prolactin levels in both group after treatment were significantly lower than those of the baseline (P < 0.01). There was no significant difference in prolactin levels between the two groups after treatment (P > 0.05). Compared with before treatment, body weight, BMI, waist circumstance, and waist-hip ratio obviously decreased after treatment, showing significant difference when compared with the control group (P < 0.05). There was no significant difference in body weight, BMI, waist circumstance, and waist-hip ratio in the control group between before and after treatment (P > 0.05).

CONCLUSIONSBoth WP and aripiprazole could lower high prolactin levels of schizophrenics with phlegm dampness type amenorrhea. They showed equivalent efficacy. But WP showed more obvious effect in reducing obesity indices.

Electronic case report forms (eCRFs) instead of the traditional paper case report forms (pCRFs) are increasingly used by investigators and sponsors of clinical research. We include a total of 14 phase III studies (8 pCRF, 6 eCRF) to compare paper and electronic data documentation both quantitatively and qualitatively in clinical studies. The result suggests that adaptions of electronic data capture (EDC) in clinical trials have the advantages in optimization of data capture process, improvement of data quality and earlier clinical decision compared to paper-based methods. Furthermore, the successful implementation of EDC requires accouplements with corresponding data management processes and reallocation of resources.
