Background The dosage of verteporfin photodynamic therapy (PDT) for central exudative chorioretinopathy(CEC) depends on the calculation formula of Treatment of Age-related Macular Degeneration with Photodynamic Therapy Study Group(TAP)and Verteporfin in Photodynamic Therapy Study Group(VIP).Some local adverse responses or normal tissue damage have been noted under the standard dose of verteporfin during the treatment of CEC.So it is necessary to explore an appropriate therapeutic dosage of verteporfin.Objective This clinical study aimed to observe and compare the clinical efficacy and safety of different doses of verteporfin PDT for CEC.Methods Ninety eyes of 90 patients with CEC were enrolled in this study with the approval of the Ethic Commission of Affiliated Second Hospital of Nanchang University.Written informed consent was obtained before PDT.The patients were randomly divided into standard dose group,half dose group and 1/3 dose group.All of the patients received PDT.Standard dose(6 mg/m2),3 mg/m2 or 2 mg/m2 of verteporfin was applied in the three groups respectively,with the laser intensity 50 J/cm2.The patients were followed-up for 3 months.Repeat treating regimen was performed in the same way in the patient with fundus fluorescein leakage after initial PDT.Results The BCVA(logMAR) value was 0.44±0.36 after PDT in the standard dose group.Visual acuity improved in 20 patients (66.67％),stabilized in 8 patients(26.67％)and decreased in 2 patients (6.67％).The BCVA showed a significant difference between the preoperative and postoperative BCVA (t =6.719,P =0.000).CNV disappeared in 19 patients (63.33％),obviously improved in 7 patients (23.33％),partially disappeared in 3 patients (10.00％) and unchanged in 1 patient (3.33％).The central fovea thickness (CFT)value was significantly declined in postoperation compared with preoperation (t =5.758,P =0.000).Eight patients received secondary PDT with the recurrence rate 26.67％.In the half dose group,visual acuity improved in 18 patients(60.00％),stabilized in 11 patients(36.67％)and decreased in 1 patient (3.33％).CNV disappeared in 16 patients (53.33％),obviously improved in 8 patients (26.67％),partially disappeared in 5 patients (16.67％) and unchanged in 1 patient (3.33 ％).Significant difference was seen between the preoperative BCVA and postoperative BCVA(t=8.294,P =0.000).The decrease of C FT was significant in postoperation(t =8.493,P =0.000).Ten patients received secondary treatment with the recurrence rate 33.33％.In 1/3 dose group,visual acuity improved in 8 patients (26.67 ％),stabilized in 12 patients (40.00％),decreased in 10 patient (33.3％).CNV disappeared in 8 patients (26.67％),obviously improved in 8 patients (26.67％),partially disappeared in 6 patients (20.00％) and unchanged in 8 patient (26.67％).There was no significant difference between the preoperative BCVA and postoperative BCVA (t =0.536,P =0.596).The difference between preoperative CFT and postoperative CFT was insignificant(t =0.942,P=0.354).Fourteen patients received secondary PDT and 8 patients received three times with the recurrence rate 73.33％.Conclusions 3 mg/m2 verteporfin PDT for CEC shows a similar clinical efficiency and safety to 6 mg/m2 verteporfin.3 mg/m2 verteporfin PDT can decrease cost,but the effect of 2 mg/m2verteporfin PDT is not satisfacted.

Objective To investigate relationship between levels of follicle-sitimulating horomone receptor(FSHR) and ovarian response induced by gonadotropin hormone,and whether the FSHR expression is correlated with in vitro fertilization(IVF) outcome.Methods Granulose cells were collected from 43 women receiving IVF-embryo transplantation(IVF-ET).According to the number of oocyte,the women were divided into three groups: low response(15).The expression intensity of FSHR was measured by immunohistochemistry technique.The expression intensity of FSHR on the granular cell,the embryological and clinical outcomes were compared and analyzed. Results The expression of FSHR was significantly different in three groups with the highest in high response group(P0.05).The FSHR level was positively correlated either with the number of oocyte (r=0.719) or with the serum E2 levels(r=0.516,P0.05). Conclusion Ovarian response to gonadotropin hormone stimulation is correlated with the level of FSHR in the granulose cells.The development of follicles may be influenced by it.

Objective To systemically review the effect of ulinastatin on lung function in pediatric patients undergoing cardiopulmonary bypass.Methods PubMed,Embase,Cochrane Controlled Trials Reg-istry,China National Knowledge infrastructure,China Biology Medicine disc,VIP and Wanfang databases were searched from their inception to October 2015.Articles regarding the use of ulinastatin on lung function in patients undergoing cardiopulmonary bypass were searched.Studies were screened by two independent re-viewers and then the data were extracted.The methodological quality was evaluated according to the inclusion and exclusion criteria.Meta-analysis was then performed using RevMan 5.1 software. Results Nineteen eligible studies (n = 657 patients)were identified.The results of meta analysis showed that ulinastatin could improve the oxygen partial pressure(SMD=0.90,95%CI 0.52-1.28,P <0.01)and oxygenation index (SMD=1.01,95%CI 0.45-1.56,P <0.01),decrease the PA-a O2 (SMD= -0.87, 95%CI -1.70--0.03,P =0.04),reduce the respiratory index (SMD=-0.81,95%CI -1.51--0.11, P =0.02),Lower the airway peak pressure (SMD=-0.83,95%CI -1.18--0.48,P <0.01),improve the dynamic compliance (Cd)(SMD=1.10,95%CI 0.57-1.62,P <0.01),and shorten the breathing ma-chine ventilation time (SMD=-0.98,95%CI -1.59--0.36,P <0.01).Conclusion This meta-analysis showed that ulinastatin treatment had a certain degree of protective effects on lung function in pediatric pa-tients undergoing cardiac surgery with CPB,but further research was needed for all these studies which were not multicenter,strictly controlled.

OBJECTIVETo explore the procedures of dynamic infusion cavernosometry and cavernosography (DICC) and their application in the diagnosis and classification of venous erectile dysfunction (VED).

METHODSThis study included 103 ED patients, aged 20 to 43 years, highly suspected of VED, with disease courses of 4 months to 6 years. DICC was performed and analyses were made on the results, especially the parameters of flow-to-maintain (FTM) and pressure decay (PD) in the corpus cavernosum.

RESULTSBased on the parameters of FTM and PD, 21 of the patients were normal, 5 were suspected of VED, 39 had mild VED, 25 had moderate VED, and 13 had severe VED. Penile subcutaneous hematoma was found in 4 of the patients, all recovered after 3 to 5 days, with no other complications.

CONCLUSIONDICC is a reliable, safe and minimally invasive method for the diagnosis and classification of VED.

Objective:To determine if suitable electric pulses-mediated DNA and DNA and bupivacaine complexes delivery technologies could enhance effects of botulinum neurotoxin serotype A (BoNT/A) DNA vaccines in mouse model. Methods:Vaccination of mice i.m. with plasmid DNA replicon vaccine pSCARSHc and conventional plasmid DNA vaccine pcDNASHc following electric pulses and with DNA and bupivacaine complexes. AHc-specific group antibody ELISA titers and lymphocyte proliferative responses of mice were detected and IgG1 and IgG2a isotype profiles were assayed. Results:Immune effects of DNA vaccines were enhanced following electric pulses and bupivacaine delivery. Effects of DNA vaccines following electric pulses were better than that of DNA vaccines formulated with bupivacaine,and the combined delivery technology of electric pulses and bupivacaine induced the highest level of specific antibodies and lymphocyte proliferative responses. Plasmid DNA replicon vaccine pSCARSHc induced relatively higher AHc-specific antibodies and lymphocyte proliferative responses in immunized Balb/c mice than conventional plasmid DNA vaccine pcDNASHc in these DNA delivery technologies. And vaccine pSCARSHc induced Th2/Th1-type immune responses with a general bias to Th2-type,and vaccine pcDNASHc induced Th2-type immune responses. Conclusion:Suitable electric pulses-mediated DNA and DNA and bupivacaine complexes delivery technologies could enhance effects of BoNT/A DNA vaccines in mouse model. Therefore,the methods described here potentially provide suitable strategies in developing an efficacious vaccine against botulinum neurotoxin serotype A.
