Background Researches showed that microperimetry can exhibit more tiny visual function damage than conventional perimetry in glaucomatous eyes.However,the study on fixation stability of glaucoma is still rare until now.Objective This study was to compare the correlation between microperimetry Maia (Macular Integrity Assessment) and Humphrey perimetry,and to investigate the changes of the fixation stability in glaucoma patients with hemifield defect.Methods This study proposal was approved by Medical Ethic Committee of Peking University First Hospital.A cross-sectional study was performed under the informed consent of each subject.Thirtyfive eyes of 35 glaucoma patients with hemifield defect by 24-2 Humphrey perimetry were included in Peking University First Hospital from December 2013 to March 2014,and 30 eyes of 30 normal volunteers served as controls.Both Humphery (10-2) and Maia (expert 10-2) were performed on the subjects respectively and the correlation of the results between Humphery (10-2) and Maia (expert 10-2) were analyzed.Then the patients with normal hemifield on Humphrey were assigned to Maia normal group and Maia abnormal group.Fixation stability differences were compared between glaucoma group and normal control group,and between Maia normal group and Maia abnormal group.Results The moderately positive correlation was found in the mean sensitivity between Maia microperimetry and Humphrey perimetry (r=0.403,P =0.001),and the average threshold of Maia microperimetry was moderately positive correlated with the mean defect (MD) of Humphrey perimetry in glaucoma patients (r=0.438,P =0.008).The fixation stability parameter P1 was (67±17)％ and (87±10)％,and that of P2 was (70±16)％ and (88±9)％;the 63％ bicurve elipse area (BCEA) was (5.08±1.55) °2and (2.21±0.60) °2,and the 95％ BCEA was (14.74± 6.04) °2 and (2.86 ± 1.17)°2 in the glaucoma group and normal control group,respectively,showing significant decreases of P1 and P2 and increases of 63％ BCEA and 95％ BCEA in the glaucoma group compared with the normalcontrol group (t=-5.604,-4.831,9.885,11.086,all at P=0.000).In Maia normal group and Maia abnormal group,the P1 was (79±8)％ and (63±17)％,the P2 was (81±10)％ and (67±16)％,the 63％ BCEA was (3.19±0.65)°2 and (5.70±1.22)°2 and the 95％ BCEA was (9.10±2.60)°2 and (19.35±5.01)°2,respectively.Compared with the Maia normal group,the P1 and P2 were significantly lower,and 63％ BCEA and 95 ％ BCEA were higher in the Maia abnormal group (t=-2.468,P=0.019;t=-2.371,P=0.024;t =5.514,P=0.000;t=5.575,P=0.000).Conclusions Maia microperimetry and Humphrey perimetry yield a good correlation for glaucomatous macular function examination.In addition,Maia microperimetry showed that fixation stability decreased in glaucoma patients with hemifield defect.

Objective:To assess the urethral mobility of normal parous women in China and explore the impacts of related risk factors on it using translabial ultrasound.Methods:Females who met the inclusion criteria in 37 tertiary hospitals from February 2017 to August 2018 were included. All women underwent standardized translabial ultrasound examination and the urethral rotation angle (URA), bladder neck position at maximum Valsalva maneuver (BNP-V) and bladder neck descent (BND) were measured. Questionnaires were used to collect basic information including age, height, weight, body mass index (BMI), past medical history, maternity history, and urinary incontinence related history. Mann-Whitney U test and multiple linear regression analysis were adopted to explore the influences of age, BMI, delivery mode and parity on normal parous women′s urethral mobility. Then, the study subjects were divided into different groups and the corresponding values of URA, BNP-V and BND were compared. Results:Compared with parous women with normal BMI and no history of vaginal delivery, those who were overweight and/or had a history of vaginal delivery were more likely to gain greater URA and BND ( P<0.05). The URA and BND were not significantly different between women with different times of cesarean sections ( P>0.05); while for women with a history of vaginal delivery, these two parameters increased with the increase of the number of transvaginal deliveries ( P<0.05). Conclusions:BMI and vaginal delivery are important risk factors for the urethral mobility of normal parous women. The urethral mobility increases with the increase of BMI and the number of vaginal deliveries.

Objective To evaluate the effect of conversion from mycophenolic acid (MPA) to mizoribine (MZR) in renal transplant recipients with gastrointestinal tract (GI) symptoms.Methods A total of 355 renal transplant recipients with GI symptoms caused by MPA administration were enrolled from April 2015 to March 2017 in 25 different renal transplant centers in China.The symptomatic improvement of GI before (baseline) and after conversion to MZR (1,2,4 weeks) was assessed by each item of GI symptoms indication.In addition,the efficacy and safety of the conversion therapy during 12 months were determined.Results Patients showed improvement in GI symptoms including diarrhea,abdominal pain,abdominal distention and stomachache after conversion to MZR 1,2,4 weeks (P＜0.05).In patients with different severity of diarrhea,conversion to MZR therapy significantly improved diarrhea (P＜0.05).During 12 months,no patient experienced clinical immune rejection.We did not observe any infections,leucopenia and other serious side effects.Conclusion MZR could markedly improve GI symptoms caused by MPA administration in renal transplant recipients.

OBJECTIVE: To investigate the relationship between the eukaryotic initiation factor 3a (eIF3a)polymorphisms and chemo-sensitivity to platinum-based drug in ovarian cancer.
 METHODS: Matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS) analysis was performed to detect 57 cases of eIF3a polymorphic genotypes (rs3824830, rs77382849, rs10787899 and rs3740556) after platinum-based chemotherapy drugs up to 6 cycles in primary ovarian cancer. The association between these gene sites was analyzed.
 RESULTS: There were 3 genotypes for eIF3a rs3824830, named AA, GA and GG. The frequency distribution for them was 43.86%, 36.84% and 15.79% (2 cases did not detect the genotype, 3.51%), respectively. There were 2 genotypes for eIF3a rs77382849, named CC and TC. The frequency distribution for them was 85.96% and 12.28%(1 case did not detect the genotype, 1.76%), respectively. There were 3 genotypes for eIF3a rs10787899, named GG, GA and AA, respectively. The frequency distribution for them was 26.32%, 47.36% and 26.32%, respectively. There were significant difference in different genotypes between age group and FIGO stage (P<0.05). The genotype of eIF3a rs10787899 GA was easier to resist platinum drug compared with the GG genotype and the odds ratio could be increased by 2.676 (95%CI: 0.544-13.159). The genotype of eIF3a rs10787899 AA was easier to resist platinum drug compared with the GG genotype and the odds ratio could be increased by 5.419(95%CI: 0.964-30.471). Rebalanced by age and FIGO stage, there was no significant difference (P>0.05) among these genotype groups. In all blood samples, there was only one genotype for eIF3a rs3740556, named GG.
 CONCLUSION There is no mutation genotype in eIF3a rs3740556 loci. Polymorphism in the eIF3a rs3824830, rs77382849 and rs10787899 doesn't affect the response of ovarian cancer to platinum-based chemotherapy.

Progressive fibrosing interstitial lung disease （PF-ILD） has a complex etiology， and is classified as lung impediment stage， impediment-atrophy combination stage， and lung atrophy stage according to the different clinical manifestations during the progression of disease. Based on the theory of opening-closing-pivoting to analyse the characteristics of yin and yang disease mechanism and the idea of prescriptions in the three stages. For lung impediment stage， main as three-Yang fail to keep inside， disharmony between Ying qi （营气） and Wei qi （卫气）， shaoyin impairment， treatment should use Mahuang （Ephedra sinica） and Guizhi （Neolitsea cassia） flexibly to form a formula， or choose pungent-dispersing formulas like Baidu Powder （败毒散） to move qi and save yang， and diffuse and disperse impediment pathogen， meanwhile combining saving-shaoyin medicinals like Fuzi （Aconitum carmichaelii） and Shudihuang （Radix Rehmanniae Praeparata） to reinforce healthy qi and dispel pathogen； for impediment-atrophy combination stage， rooted as yangming impairment and progressed by over-movement of qi， treatment should use Mahuang Shengma Decoction （麻黄升麻汤） to resolve and decrease over-activities， emphasis on both opening and closing， and improve impediment and atrophy； for lung atrophy stage with three-Yin in a bad condition simultaneously and poor prognosis， treatment should use modified Jinshui Liujun Decoction （金水六君煎） to consolidate qi and save yin， disperse phlegm and stasis， to improve the quality of life for patients with PF-ILD.

BACKGROUNDOur goal was to evaluate the outcomes of kidney transplants from controlled cardiac death donors compared with brain death donors by conducting a meta-analysis of cohort studies.

METHODSThe PubMed database and EMBASE were searched from January 1980 to July 2013 to identify studies that met pre-stated inclusion criteria. Reference lists of retrieved articles were also reviewed. Two authors independently extracted information on the designs of the studies, the characteristics of the study participants, and outcome assessments.

RESULTSNine cohort studies involving 84 398 participants were included in this meta-analysis; 3 014 received kidneys from controlled cardiac death donors and 80 684 from brain death donors. Warm ischemia time was significantly longer for the controlled cardiac death donor group. The incidence of delayed graft function was 2.74 times (P < 0.001) greater in the controlled cardiac death donor group. The results are in favor of the brain death donor group on short-term patient and graft survival while this difference became nonsignificant at mid-term and long term. Sensitivity analysis yielded similar results. No evidence of publication bias was observed.

CONCLUSIONThis meta-analysis of retrospective cohort studies suggests that the outcome after controlled cardiac death donors is comparable with that obtained using kidneys from brain death donors.
