Objective To evaluate effects of simultaneous inhibition of mammalian target of rapamycin complex 1(mTORC1)kinase and glycogen synthase kinase-3β(GSK-3β)on phosphorylation of 4E-binding protein-1(4EBP1), cap-dependent translation, as well as survival and apoptosis of melanoma cells. Methods Cultured A375 cells were classified into several groups to be treated with dimethyl sulfoxide (DMSO group), the mTORC1 kinase inhibitor everolimus at a concentration of 5 nmol/L (everolimus group), the GSK-3β kinase inhibitor AR-A014418 at a concentration of 10 μmol/L (AR-A014418 group), or 5 nmol/L everolimus and 10 μmol/L AR-A014418(combined treatment group). After additional culture, Western-blot analysis was performed to measure protein expressions of phosphorylated 4EBP1 (p4EBP1)and survivin in A375 cells, m7GTP pull down assay to estimate interaction between eukaryotic initiation factor-4E (eIF4E)and eIF4G, cell counting kit 8 (CCK8)assay to evaluate cell proliferation, and flow cytometry to detect cell apoptosis. Results Both everolimus and AR-A014418 had inhibitory effects on 4EBP1 phosphorylation and survivin expression. The expressions of p4EBP1-65 and survivin were both significantly decreased in the everolimus group (0.74 ± 0.05 and 0.71 ± 0.06 respectively), AR-A014418 group (0.62 ± 0.06 and 0.58 ± 0.07 respectively)and combined treatment group (0.14 ± 0.04 and 0.09 ± 0.05 respectively)compared with the DMSO group (1.00 ± 0.07 and 1.00 ± 0.06, respectively, all P < 0.001), with the most significant decrease observed in the combined treatment group. As m7GTP pull-down assay showed, the everolimus group, AR-A014418 group and combined treatment group all showed significantly lower relative expression levels of eIF4G(0.72 ± 0.04, 0.67 ± 0.05 and 0.12 ± 0.05 vs. 1.00 ± 0.06, all P < 0.001), but significantly higher relative expression levels of 4EBP1 (1.98 ± 0.16, 2.32 ± 0.17 and 7.58 ± 0.25 vs. 1.00 ± 0.08, all P < 0.001)than the DMSO group, and the combined treatment group showed the lowest eIF4G expression but highest 4EBP1 expression. After 24-hour culture, the proliferation of A375 cells was inhibited by 18.5% ± 1.3% in the everolimus group, 19.8% ± 1.8% in the AR-A014418 group, and 61.2% ± 2.1% in the combined treatment group compared with the DMSO group, with the strongest inhibition noted in the combined treatment group. The inhibitory effects of everolimus and AR-A014418 on cell proliferation increased over time, and showed the same trend at 48 hours. Flow cytometry showed that the apoptosis of A375 cells was accelerated by the 24-hour treatments with everolimus and AR-A014418 alone or in combination, with the apoptosis rate being 14.28% ± 2.18%, 14.57% ± 2.35% and 55.18% ± 6.27% in the everolimus group, AR-A014418 group and combined treatment group respectively, and the combined treatment showed the strongest accelerating effect. Conclusion The combined treatment with everolimus and AR-A014418 can evidently inhibit 4EBP1 phosphorylation and eIF4F complex formation in A375 cells, which then suppress cap-dependent translation and promote apoptosis of melanoma cells.

Objective To explore the effects of Compound Malt Pill on gene expressions of androgen receptor (AR) and insulin receptor (INSR) in polycystic ovarian syndrome (PCOS) rats; To discuss its relevant mechanism of action.Methods Letrozole was used to induce and establish rat models. Rats were randomly divided into normal group, model group, Diane-35 group, low-, medium- and high-dose Compound Malt Pill groups. The normal group and model group received normal saline by gavage; the Diane-35 group was given Diane-35 by gavage; Compound Malt Pill groups were respectively given different concentrations by gavage for 21 d. The levels of serum testosterone (T) and insulin were measured by ELISA, and the gene expressions of AR and INSR were measured by RT-PCR. Results Compared with normal group, the serum T, insulin and the gene expressions of AR and INSR in model group increased significantly (P<0.05,P<0.01); compared with model group, the serum T, insulin and the gene expressions of AR and INSR in low-, medium- and high-dose Compound Malt Pill groups decreased significantly (P<0.05, P<0.01).Conclusion Compound Malt Pill can adjust endocrine-metabolic disorder in PCOS rats.

Abstract: Objective　To analyze the impact of the flood disaster on the distribution of Oncomelania snails in 2020 in Wuhu City, to provide scientific basis for formulating the "14th Five-Year Plan" for schistosomiasis control and precise prevention and control measures in Wuhu City. Methods　Systematic sampling combined with environmental spot check was used to investigate the distribution of snails in the historical snail's environment, existing snail's environment and suspected snail's environment in Wuhu City. The collected snails were crushed and examined by microscope to understand the death and life of snails and the infection of Schistosoma japonicum, and the density of live snails and other indicators were counted. Results　The historical area of snails was 14 475.24 hm2 in Wuhu City, and the existing area of snails was 4 588.72 hm2, including 4 210.32 hm2 for lake type and 378.40 hm2 for hill type snails. The average occurrence rate of live snails was 14.59%, and the average density of live snails was 0.50 snails/0.1 m2 in Wuhu City. There were 2 745 snail breeding environments, of which 491 were lake type and 2 254 are hill type, accounting for 17.89% and 82.11% respectively. The existing snail area was mainly distributed in the beaches and ditches, accounting for 92.51% and 6.29% of the existing snail area respectively. Some snails were distributed in ponds, paddy fields and other environments. Among all the historical snail habitats, the majority were class Ⅱ and class Ⅲ environments (which still have the basic conditions for snail breeding at present), with a total of 1 739 sites (blocks), accounting for 63.35% of the total environment. No schistosomiasis infected snails have been found, and the newly discovered and recovered snails cover an area of 268.21 hm2 in Wuhu City. Conclusions　The distribution of snails is extensive in Wuhu City, and snails are mostly distributed in beaches, which are vulnerable to the impact of flood disasters. The spread of Oncomelania snails is found in 30 marshlands in 3 counties in this survey. It is necessary to continue to strengthen snail monitoring after disasters, and take class Ⅱ and class Ⅲ environments as key areas for snail monitoring, so as to find, identify and evaluate the risk of schistosomiasis transmission as soon as possible, to avoid or reduce the impact of flood disasters on the process of schistosomiasis control, and promote the process of schistosomiasis elimination.

OBJECTIVETo compare the clinical effects of circumcision and the foreskin-deglove plus shaft-fix (FDSF) procedure in the treatment of phimosis or redundant prepuce in obese adult males (body mass index [BMI] ≥ 28 kg/m²).

METHODSForty-four obese adult men with phimosis or redundant prepuce underwent circumcision (n = 24) or FDSF (n = 20) according to their own wishes. The patients in the circumcision and FDSF groups were aged (26.38 ± 4.24) and (26.90 ± 3.14) years, with BMIs of (27.77 ± 0.77) and (28.07 ± 2.28) kg/m² and penis lengths of (3.51 ± 0.46) and (3.50 ± 0.59) cm, respectively. The operations were performed under local anesthesia with lidocaine plus ropivacaine mesylate.

RESULTSThe operation time of circumcision was (28.04 ± 2.65) min and that of FDSF was (45.45 ± 3.49) min. At 6 months after surgery, normal penile erection was found in all the patients, the penis length was significantly longer in the FDSF than in the circumcision group ([5.01 ± 0.73] vs [3.70 ± 0.47] cm) , and the rate of satisfaction with penile appearance was markedly higher in the former than in the latter group (3.25 ± 0.71 vs 2.83 ± 0.56).

CONCLUSIONThe foreskin-deglove plus shaft-fix procedure under local anesthesia with lidocaine and ropivacaine mesylate may achieve desirable penile erection and appearance in the treatment of phimosis or redundant prepuce in obese adult patients.

With more and more attention and investment on acupuncture scientific researches, considerable outcomes and achievements has been acquired, but the shortcoming of low transformation rate of acupuncture research achievements is gradually exposed. Nowadays there is no related report on this problem, so based on achievement translational research in other areas and practical situation of acupuncture, the existing problems and solutions are analyzed. As a result, the existing problems include (1) the research content is mainly basic research and clinical research but less acupuncture device research, leading to limited transformation efficiency; (2) the evaluation system and transformation pattern are still needed to be perfect. The solutions are (1) to properly evaluate the research achievements of acupuncture, (2) to advocate the concept and method of translational medicine, (3) to reform the policy and system, and (4) to establish valid platforms covering research, outcomes and transformation.

Objective To evaluate the safety and efficacy of magnetic resonance-guided focused ultrasound surgery (MRgFUS) in treatment of symptomatic uterine leiomyoma among Chinese reproductive age women.Methods From April 2010 to April 2012,80 premenopausal women with symptomatic leiomyoma volunteered to participate in this prospective study in Department of Outpatient of Peking Union Medical College Hospital.Among 23 reproductive aged patients with size of uterus less than 16th gestational weeks,2.5 to 10 cm of diameter of myoma,less than 10 myomas and expressing symptoms clearly were treated by MRgFUS.Treatment data,non-perfused volume ratio (NPVR) and adverse events were recorded.After treatment,patients were followed up at 1 week,1,3,6,12 and 24 months,respectively.Patients at initial screening and each time of the follow-up filled out uterine fibroid symptoms quality of life (UFS-QOL),which include symptoms severity score (SSS) and health-related quality of life (HRQL).The volumes of leiomyoma and uterine were evaluated on MRI before and after the treatment (at 6 and 12 months,respectively).Before operation,routine blood test were performed on all patients,anemia patients at 3 months and 1 year after treatment were checked with blood test.Results (1) Treatment data and adverse events:the mean therapeutic temperature was (69 ± 7) ℃,the mean treatment time was (144 ±62) min,the mean NPVR was (62 ±23)％.Adverse events included mild erythema(1/23),abdominal cramp(8/23),vaginal discharge (5/23),and leg numbness (4/23).(2) The rate of secondary surgery:one patient was treated by myoectomy and hysterectomy within one year following up and 4 patients chose surgical treatment during the second-year follow-up.(3) Volume change:the volumes of leiomyoma before the treatment and 6,12 months after the treatment are 75.6 (P25 =43.8,P75 =128.9),52.3 (P25 =23.8,P75 =111.2),45.9 (P25 =26.3,P75 =71.7) cm3,respectively; and the volumes of uterine before the treatment and 6,12 months after the treatment are 270.0 (P25 =208.4,P75 =390.3),216.4 (P25 =151.1,P75 =290.0),200.0 (P25 =149.1,P75 =267.6) cm3,respectively.Both leiomyoma and uterine volumes decreased significantly after treatments (P ＜ 0.01).(4) UFS-QOL change:the symptoms severity score (SSS) before the treatment and 3,12 months after the treatment are (34 13),(22 ± 11),(19 ± 12),which decreased significantly (P ＜ 0.01).The health-related quality of life (HRQL) before the treatment and 3,12 months after the treatment are (74 ± 15),(82 ± 13),(89 ± 10),which increased dramatically (P ＜0.01).(5) Hemoglobin(HGB) change:eleven patients suffered from anemia before treatments,the mean HGB before treatment was (87 ±6) g/L and were (106 ± 14) g/L 3 months after treatment,(112 ± 10) g/L 12 months after treatment.The HGB was increased significantly after treatments (P＜0.01).Conclusions MRgFUS is a safe and effective non-invasive management for symptomatic uterine leiomyoma in short-term follow up.But there is additional treatment ratio after MRgFUS.

Objective To explore the mechanism of resistance to beta-lactam antibiotics of Moraxella catarrhalis (Me) in children with lower respiratory tract infection, to guide the rational and objective administration and provide measures of avoiding changes of antimicrobial resistance of Mc. Methods Total 40 strains Mc with positive beta-lactamase were taken from lower respiratory tract of hospitalized children with pneumonia from July to December in 2006. Polymerase chain reaction technology was used to amplify genes. The DNA product of the 40 strains were digested by restriction enzyme (BCgI). The expression and type of the drug resistance gene (BRO) for ampicillin according to different strap in agarose gel electrophoresis were analyzed. Clinical characteristics of different genotype was studied. Results Among 40 strains Me with positive Nitrocefin disk, positive BRO-1 gene was 90.0% while positive BRO-2 gene was 7.5%, and another 2.5% was neither positive BRO-1 gene nor positive BRO-2 gene. BRO-3 or TEM-1 enzyme produced may be the possible cause. The diameter of inhibition zone to beta-lactam antibiotics of Mc was smaller in positive BRO-1 gene than that Mc of positive BRO-2 gene. Conclusions BRO-1 gene was the main genotype of Mc with beta-laetamase positive in our study.
