OBJECTIVETo evaluate the safety and clinical outcomes of the novel simplified no-flip surgical approach to Shang Ring male circumcision in adults.

METHODSA total of 528 adult males, aged 18 - 58 (mean 35) years, 63 with phimosis and 465 with redundant prepuce, underwent no-flip Shang Ring circumcision with or without removal of the outer ring. The operation time and intraoperative blood loss were recorded and observations were made on such complications as postoperative bleeding, infection, edema, and wound dehiscence.

RESULTSThe operation time, intraoperative blood loss, and 2-hour postoperative pain score were (3.8 +/- 0.3) min, (0.6 +/- 0.1) ml, and 7.3 +/-0.3, respectively. Spontaneous ring detachment occurred at 21.6 +/- 2.1 days postoperatively in 12.7% of the patients (67/528) who had chosen not to remove the rings. Of those who preferred removal of the outer ring (87.3% [461/528]), none experienced any pain at the ring removal 7 days after the operation. Postoperative complications included infection in 3 cases (0.56%) and mild edema in 9 (1.70%), but no bleeding and wound dehiscence. Totally, 518 (98.1%) of the patients felt satisfied with the postoperative penile appearance.

CONCLUSIONNo-flip Shang Ring circumcision, with no need for removal of the inner ring, is a safe and simple approach for adult males, which is superior to conventional Shang Ring circumcision for requirement of fewer surgical instruments, shorter operation time, lower incidence of complications, and better satisfaction with the penile appearance. However, these advantages are to be further demonstrated by more randomized controlled trials.

Six bacterial strains with malachite green decolorization ability were isolated from a sediment of aquaculture pond, and strain M6 was selected by further enrichment culture in nutrition broth with malachite green and decolorization rate comparison. The decolorization rate of strain M6 to malachite green was 97.14% in the conditon of 30?C and 150 r/min, and its morphology was observed by gram stain and electronmicroscopy, its physiological and biochemical characteristic was studied by ATB bacteria identification in-strument for identification of bacteria, and its 16S rDNA sequence was determined following PCR amplifi-cation, the sequence was aligned and the phylogenic tree was instructed with those bacterial strains of high identity with strain M6. In addition, its growth characteristics was also studied. The experimental results showed that strain M6 was gram negative and bacilliform with a flagellum at one end. Its size was 0.45 ?m ?0.84 ?m. Its colony produced on common agar plate appeared as round, light blue, dense, hard to choose; 16S rDNA sequence of strain M6 had high identity of 98%～99% with Pseudomonas sp. located in GenBank and strain M6 had the most close relative relation to Pseudomonas putida OW-16 (Locus number: DQ112328.1). Combined the results of the traditional morphological, physiological, biochemical character-istics and 16S rDNA sequence analysis, strain M6 was identified as Pseudomonas putida (Locus number: EU348741.1). Additionally, its growth curve in the condition of 30?C and 150 r/min was as follows: lag phase was 0～4 h, log phase was 4 h～64 h, stationary phase was 64 h～80 h, decline phase was after 80 h. Its best growth conditions were pH 7 and 30?C,and in the rotational speed of 50 r/min to 250 r/min. Its concen-tration increased with the increase in rotational speed.

BackgroundWhether the peeling of the inner limiting membrane (ILMP) increase the closure rate of idiopathic macular hole is still in controversy.Some ophthalmologist recommend vitrectomy combined with inner limiting membrane peeling for the treatment of idiopathic macular hole.However,the removal of ILMP is difficult because of its similar appearance to adjacent tissues.Objective This study was to investigate the efficacy of triamcinolone acetonide(TA) and indocyanine green(ICG) double staining-assisted vitrectomy combined with ILM peeling during the surgery.Methods A consecutive case- observational study was designed.The standardized vitrectomy was performed in 25 eye of 23 cases with IMH.During the vitrectomy,TA and ICG were injected into posterior pole vitreous to visualize and assist the ILM peeling.The dying effectiveness was observed,and the closure rate of macular hole,visual acuity,intraocular pressure and complications were evaluated after surgery.Written informed consent was obtained from each patient prior to operation.Results Posterior vitreous cortex and ILM were visible and the residual vitreous and cortex were removed clearly after dying of TA and ICG in all the 25 eyes.During the following-up duration of 3-8 months,the completely anatomical reattachment of the macular area was in 22 eyes ( 88.0％ ) and partially reattachment in 3 eyes( 12.0％ ).The best corrected vision was 0.07-0.60 in all of the operated eyes 2 months after surgery.Conclusions TA and ICG- assisted vitrectomy combined with ILM peeling appears to be a safe and effective method for IMH repair.

Objective To establish a specific,sensitive,simple human respiratory adenovirus detection method to put a good experimental foundation for developing universal and specific diagnostic reagents of human respiratory adenovirus.Methods The nucleotide sequences of 10 serotype of human respiratory adenovirus were obtained from GenBank.Highly consewed five pairs of universal and specific adenovirus primers were designed on the evaluation of multiple sequence alignment of the 10 full genomic sequences with the software DNAMAN 5.2.2,Gene Runner 3.05,BLAST,and to ensure that the polymerase chain reaction(PCR)products were type-specific.NP-40 sample lytic method was employed to prepare the template.The effectiveness,specificity and sensitivity of primers were evaluated.And PCR was carried out to test 64 samples of throat swabs of acute respiratory infection children.The positive PCR products were sequenced directly to identify the adenovirus serotypes.The positive specimens was inoculated on HeLa cells to observe cytopathie effect(CPE)under light microscope,and virus morphology were observed under electron microscope.Results BLAST results indicated that the five pairs of primers were specific adenovirus primers with low homology to the others.The primers were identified as PCR positive fragments obtained by using five pairs of primers to amplify the human adenovirus type 3 DNA,which did not react to the respiratory syncytial virus and Coxsackie virus.the effectiveness and specificity of the primer were thus indicated.PCR sensitive results showed 10-5 dilutin of adenovirus culture and DNA sample could be deteeted which meant the method was sensitive and stable.Two PCR positive specimens were detected in 64 clinical samples.the positive rate was 3.13%(2/64).Using the two PCR positive specimens to inoculate the HeLa cells,the typical adenovirus CPEs of rounded and aggregated,detatched cells were observed under light microscope.And a large number of adenovirus typical particles with characteristic lattice arrangement were observed in the infected cells under electron microscope.PCR product sequencing results showed that these two isolated adenoviruses were typed in human adenovims group B.Conclusions Universal and specific adenovirus PCR primers with the serotype specificity of the PCR products were designed successfully.The PCR primers was sensitive and specific and could be routinely applied in clinical adenovirus diagnosis for respiratory specimens.

italic>Helicobacter pylori (H. pylori) can cause a variety of digestive tract diseases, the serious may develop into gastric cancer. Nowadays, H. pylori infection rate exceeds 50%, and its eradication rate is declining due to the continuous increase of drug resistance, leading to the occurrence of plenty of stubborn infections, which seriously threaten human health. At present, it is difficult to achieve satisfactory curative effect by increasing the types of antibiotics combination or increasing their dose. In this review, the clinical treatments of H. pylori were introduced. Proceed from the characteristics and pathological background of H. pylori infection that makes H. pylori difficult to eradicate, the research advances of drug delivery strategies for improving H. pylori eradication rate were reviewed, such as strategies that could increase drug concentration in stomach (e.g. drug delivery systems with gastric acid-stabilized ability), increase drug concentration in H. pylori colonization sites (e.g. drug delivery systems with gastric retention or H. pylori targeted abilities), overcome H. pylori resistance (metal nanoparticles, anti-biofilm delivery systems), enhance host immune response (vaccine preparation) and so on. Novel drug delivery systems, such as cell membrane coating technology and phage therapy, are comparatively rare in the field of anti-H. pylori, but have broad application prospects. This review would provide reference for the development and application of therapeutic strategies to improve H. pylori eradication rate.

OBJECTIVETo observe the effect of novel air neuromodulator H2S on platelet function of L-Arg transport for discussing H2S of effect on platelet function.

METHODSSaturate H2S solution as donate made rat rich platelet plasma and pre-incubation rat platelet with different density of H2S. To measure the velocity of L-Arg transport in platelet by radioactivity technique.

RESULTSAt different concentrations of H2S (6.25, 12.5, 25, 50, 100 micromol/L), the velocity of L-Arg transport was lower than that in control. H2S reduced rapidly the Vmax and velocity of L-Arg transport in platelet (P < 0.05) and this effect had no effect to Km.

CONCLUSIONH2S can affect platelet function by changing rapidly platelet L-Arg transport system function.

In 2013, the World Health Organization reported the first case of human infection with a new influenza A (H7N9) virus in China. This has caused damage and panic within certain areas in China. Therefore, analysis of this virus with bioinformatics technology is very necessary. Neuraminidase (NA) is one of the most important antigens of the influenza virus and an important target for anti-flu drugs. In this study, the nucleotide and protein sequences of NA gene of A/H7N9 influenza viruses were retrieved from the NCBI database, and MEGA 5.0 software was employed to construct a phylogenetic tree based on the nucleotide coding sequence; BioEdit software was used to align the nucleotide and protein sequences of NA and calculate the homologies of nucleotides and amino acids and then to analyze the important mutation sites of NA gene. The results demonstrated that the spread of influenza virus H7N9 showed certain geographical and temporal relations. The H7N9 virus isolated from China in 2013 belonged to Euroasiatic serotype, and its NA stalk region hadobvious variation, which may be one of the reasons that this virus infects human. These analyses may be very helpful for understanding the evolutionary relationship and mutation trend of A/H7N9 influenza viruses.

OBJECTIVETo investigate the etiology and therapy of delayed graft function (DGF) recovery in renal transplant recipients.

METHODSThe clinical data were retrospectively analyzed in 15 renal recipients with DGF. All the 15 patients received hemodialysis along with pulse treatment against acute rejection (AR), or immunosuppressant adjustment, or in situ retransplantation after the resection of the original transplanted kidney according to different etiological factors.

RESULTSAmong the 15 patients, 8 developed AR, 5 showed acute renal tubular necrosis (ATN), 1 had grafting-associated renal vein embolism and 1 had acute cyclosporine nephrotoxication. The renal function recovered within 10 to 35 days after transplantation without complication during the follow-up period (0.5-3.0 years).

CONCLUSIONDGF is a common complication after kidney transplantation mainly due to the occurrence of AR and ATN. Good prognosis is expected if etiology-oriented therapy is performed properly and promptly.

OBJECTIVETo observe the efficacy and safety of modified Shengma Biejia Decoction (MSBD) combined with CAG program in treating elderly acute myeloid leukemia (AML) patients with yin deficiency toxin stasis syndrome (YDTSS).

METHODSTotally 46 elderly AML patients were assigned to the treatment group (24 cases; treated with MSBD + CAG) and the control group (22 cases; treated with CAG + placebos of Chinese medicine) according to random digit table. The therapeutic course of CM placebo or MSBD was 21 days. The clinical efficacy and adverse reactions were observed. Meanwhile, physical state (ECOG Score), transfusion dependency, and TCM syndrome score were compared before and after treatment.

RESULTS(1) The complete remission rate was 54% (13/24) and the objective response rate (ORR) was 71% (17/24) in the treatment group, obviously higher than those of the control group [36% (8/22); 54% (13/24)], with statistical difference (P = 0.036, 0.042). When comparing the efficacy based on risk level, the moderate and poor ORR was 71% (10/14) and 67% (6/9) in the treatment group, and 57% (8/14) and 33% (2/6) in the control group, with statistical difference between the two groups (P = 0.048; P = 0.010). (2) Compared with before treatment in the same group, the ECOG score significantly decreased, the average infusion time of red cells and platelets were markedly prolonged in the treatment group after treatment (P < 0.05). ECOG score, the average infusion time of red cells and platelets were significantly better in the treatment group than in the control group after treatment (P < 0.05). (3) Compared with before treatment in the same group, scores of fever, hemorrhage, and bone pain were markedly reduced in the control group (P < 0.05); scores of fever, fatigue, hemorrhage, dry mouth, and bone pain were markedly reduced in the treatment group (P < 0.05). Better effect in relief of fever, fatigue, hemorrhage, dry mouth, and so on was obtained in the treatment group than in the control group (P < 0.05). (4) In aspect of hematotoxicity, the incidence of neutropenia, anemia, thrombocytopenia was obviously lower in the treatment group than in the control group [29.2% (7/24) vs 54.5% (12/22); 16.7% (4/ 24) vs 45.5% (10/22); 33.3% (8/24) vs 63.6% (14/22); P < 0.05]. The incidence of fatigue and anorexia was obviously lower in the treatment group than in the control group [37.5% (9/24) vs 63.6% (14/22), 37.5% (9/24) vs 81.8% (18/22); P < 0.05].

CONCLUSIONMSBD combined with CAG program in treating elderly AML patients with YDTSS, with efficacy enhancing toxicity reducing effect, had distinct advantages in improving physical condition and clinical symptoms, and reducing transfusion dependency.

OBJECTIVETo observe the effect of CKJ Recipe (consisting of Cordyceps sinensis polysaccharide, amygdaloside, and gypenosides) containing serum on the activation of rat primary hepatic stellate cells (rHSCs) and to explore its pharmacological mechanism.

METHODSrHSCs were isolated form liver and cultured for four days. Then they were divided into the normal control group, the model group, and the CKJ group. rHSCs in the model group and the CKJ group were treated with 2.5 ng/mL transforming growth factor beta1 (TGF-beta1) in serum-free DMEM for 24 h. Serum free DMEM (containing no TGF-beta1) was taken as the control for the normal control group. rHSCs in the CKJ group were treated with 5% CKJ-containing serum for 24 h. rHSCs in the other two groups were treated with 5% blank serum for 24 h.The protein expression level of a smooth muscle actin (alpha-SMA) was determined using high throughput screening (HCS) and Western blot. mRNA expression levels of alpha-SMA, collagen I (Col-I), platelet-derived growth factor receptor beta (PDGF-betaR), TGF-beta1, transforming growth factor beta receptor 1 (TGF-betaR1), and transforming growth factor beta receptor 2 (TGF-beta R2) were detected using quantitative RT-PCR.

RESULTSCompared with the normal control group, the protein expression level of alpha-SMA, mRNA expression levels of alpha-SMA, Col-I, PDGF-betaR, TGF-beta1, TGF-betaR1, and TGF-betaR2 significantly increased in the model group (P<0.05, P<0.01). Compared with the model group, the protein expression level of alpha-SMA, mRNA expression levels of alpha-SMA, Col-I, PDGF-betaR, TGF-beta1, TGF-beta1, and TGF-beta R2 significantly decreased in the CKJ group (P<0.05, P<0.01).

CONCLUSIONCKJ containing serum could inhibit the protein expression level of o-SMA, which was probably related with inhibiting TGF-beta1 and its related receptors.
