Background Many methods are widely studied to improve the therapeutic effect of trabeculectomy for glaucoma,and the clinical effectiveness of the amniotic membrane application during trabeculectomy is one of the research hotspots.Objective This study was to evaluate the efficacy and safety between trabeculectomy with (TE-AMT) and without amniotic membrane transplantation (TE-noAMT) for treating glaucoma.Methods Articles published from 1965 to December 2010 were searched from The Cochrane Library,PubMed,EMBASE,CNKI,Chinese Biomedicine Database,internet by computer,and manual search then was performed according to the predetermined strategy.Randomized controlled trials (RCT) on TE-AMT and TE-noAMT were included.The quality of included articles were scored based on Jadad table,and the relative parameters and information were extracted,including author,design of the trials,country,number of eyes and patients,gender,follow-up duration,age,classification of glaucoma,baseline IOP and loss rate.The main analysis indicators were the percentage of IOP reduction,completely operative successful rate,qualified success rate and adverse events.The pooled estimates were carried out with RevMan version 5.0 software.Results Nineteen RCTs documents were reviewed by meta-analysis with the Jaded scores ≥3 in 2 papers and ＜3 in 17 papers.Total 977 eyes of 818 patients were included.The weighted mean differences (WMD) of the percentage of IOP from baseline were (WMD =8.47％,95％ CI:5.20-11.75) at 6 months and (WMD=9.37％,95％ CI:4.97-13.77) at 12 months postoperatively.Relative risk (RR) of complete success rate and qualified success rate at postoperative 6 months were (1.40,95％ CI:1.19-1.65) and (0.47,95％ CI:0.22-1.00),respectively.RR values of adverse event such as shallow anterior chamber,hyphema,hypotony and choroidal detachment,failed filtering blebs at 6,12 months were 0.51 (95 ％ CI:0.30-0.85),0.43 (95％ CI:0.20-0.92),0.51(95％CI:0.26-1.00) and 0.57(95％CI:0.14-2.31),0.31(95％CI:0.20-0.47),0.31 (95％ CI:0.17-0.55),respectively.Conclusions TE-AMT appears to have better efficacy in lowering IOP,increasing complete success rate and reducing adverse event I in comparison with TE-noAMT.

Abstract: Objective　To analyze the epidemic characteristics of soil-transmitted helminth (STH) by the spatial epidemiological method in Jiangxi Province. Methods　Surveillance data of STH in Jiangxi Province from 2016 to 2019 were collected for descriptive epidemiological analysis. The space-time permutation distribution of STH infection areas was analyzed with spatial autocorrelation, hotspot analysis methods and retrospective space-time permutation scan statistics. Results　The infection rates of STH were 1.32% (947/71 766), 1.14% (803/70 547), 0.87% (604/69 507) and 0.90% (628/69 620), respectively, and the differences were statistically significant in different years (P<0.01). The rates of hookworm infection were 0.65% (466/71 766), 0.64% (450/70 547), 0.48% (336/69 507) and 0.52% (362/69 620), respectively, and the differences were statistically significant (P<0.01). The infection rates of Ascaris lumbricoides were 0.55% (393/71 766), 0.41% (287/70 547), 0.32% (221/69 507) and 0.32% (225/69 620), respectively, and the differences were statistically significant in different years (P<0.01). The infection rates of Trichuris trichiura were 0.17% (125/71 766), 0.10% (74/70 547), 0.08% (57/69 507) and 0.07% (49/69 620), respectively, and the differences were statistically significant among different years (P<0.01). The results of global spatial autocorrelation analysis showed that there was a spatial autocorrelation index Moran's I value of hookworm infection rate in 2016, Trichuris trichiura infection rate in 2016, 2018 and 2019, with statistical significance (P<0.05). The results of hotspot analysis, SaTScan and FleXScan spatial and temporal scanning analysis showed that there were high-value aggregation regions for each species in each year. Conclusion　The infection rates of STH, hookworm, Ascaris lumbricoides and Trichuris trichiura showed a decreasing trend and space-time clustering from 2016 to 2019. It should be taken into account in the formulation of control strategies.

Objective To evaluate the safety and feasibility and clinical effectiveness of living relative donor kidney transplantation(LDKT)and summarize its clinical experience. Methods The clinical data of 30 cases of LDKT were retrospectively analyzed.Except for 2 cases being donated by spouse,the others were donated by blood relative donors.6 cases shared two haplotypes,and 22 cases shared one haplotype,and one case 4 mismatched,and 1 fully mismatched.All donors underwent open nephroectomy,in which 7 cases donated right kidneys and 23 donated left kidneys.In 30 cases of recipients,1 case received cadaver donor kidney transplantation and lost her allograft because of superacute rejection.Triple-combined immunosuppressive protocols consisted of calcineurin inhibitor (CNI),mycophenolate mofetil(MMF)or azathioprine(AZa)and steroid. Results All donors'hospital stay was 7 to 10 days postoperatively without any surgical complications. All donors kept their normal kidney function within 3 to 6 months'follow-up.Except for 1 case of death because of lung in fection,29 cases of recipients survived,in which 28 cases kept their normal function kidney within 1 to 4 years of follow-up and 1 case occurred chronic allograft nephropathy after one year.Except one case of DGF,29 cases of recipients retained their normal kidney function in 3 to 5 days postoperatively.Rejection episodes occurred in 4 cases,of which 3 cases were reversed by methylprednisone and 1 case by antithymocyte globulin(ATG)and Tacrolimus.Pneumonia developed in 3 cases,of which 2 cases were cured and 1 case failed.Hematoma was found around allograft in 1 case and wag surgi cally removed.Urinary leakage was happened in 2 cases of recepients and were cured by conservative treatment. Conclusions LDKT is safe and feasible with good long-term results and more advantages such as optimal HLA matches and less ischemia time and lower acute rejection,low-dose immunosup pressants.

Objective To explore the etiology,clinical manifestations of infantal viral pneumonia in Luzhou area.Methods Five viral specific serum IgM antibodies were detected by enzyme-linked immunosorbent assay(ELISA) in acute period of viral pneumonia.Five kinds of virus were separated,as respiratory syncytial virue(RSV),influenza virus(IFV),adenovirus(ADV),cytonegalo virus(CMV),and parainfluenza virus(PIV).Serum specific IgM was positive,C-reactive protein(CRP) was less than 8 mg/L,and there was no(clini-)cal and laboratory proof of other pathogenic infection detected in 221 infants with pneumonia.Results 1.One hundred and four cases of viral infection were detected from 221 infants with pneumonia.The viral positive detected rate was 47.1%,and there were 75 cases of single viral infection(72.1%) and 29 cases of mixed viral infection(27.9%) among them.2.In the single viral infection,RSV was the first,IFV,ADV,PIV and CMV being the second,the third,the fourth,and the fifth respectively.3.The types of likely infection virus were different in different age-stage and seasons in infants.Conclusions The etiology of infantal pneumonia is complicated.The types of viral infection are various besides germ infection and the epidemic season peak;clinical manifestations are different.Earlier detection of(etiology) in infection will make clear the etiology and then take appropriate treatment measures to improve curative effect.

OBJECTIVETo evaluate the effect of the platelet-derived growth factor-BB (PDGF-BB) on the phenotypic transformation of corpus cavernosum smooth muscle cells (CCSMC) in SD rats.

METHODSCCSMCs were primarily cultured in the modified tissue sticking medium and subjected to immunofluorescence assay. The cells were divided into a blank control and four PDGF-BB groups, the latter exposed to 5, 10, 20, and 40 ng/ml of PDGF-BB, respectively, for 24 hours, and the cells in the 20 ng/ml PDGF-BB group treated for 24, 48, and 72 hours. The the relative expressions of α-SMA, SMMHC, calponin, and OPN mRNA were determined by real-time fluorescence quantitative RT-PCR (qRT-PCR).

RESULTSThe α-SMA positive rate of the CCSMCs was over 95%. Compared with the blank control group, the expression levels of α-SMA, SMMHC, and calponin mRNA were significantly decreased (P < 0.05) while that of OPN mRNA remarkably increased (P < 0.05) in the PDGF-BB groups. The 20 ng/ml PDGF-BB group also showed significantly downregulated expressions of α-SMA, SMMHC, and calponin mRNA (P < 0.05) and upregulated expression of OPN mRNA (P < 0.05) at 24, 48, and 72 hours.

CONCLUSIONPDGF-BB can induce the transformation of the phenotype of CCSMCs in SD rats from the contractile to the synthetic type.
