Research progress of awareness and acceptance of HPV vaccination among males / 中华全科医师杂志

Human Papillomavirus (HPV) infection is very common in sexually active men and women. HPV vaccination is the most effective measure for primary prevention for HPV infection and HPV-related diseases ultimately. HPV infection can cause condylomata acuminata in males, and is also associated with penile cancer, anal cancer and oral cancer; however, most male HPV carriers do not have signs or symptoms, so prevention and treatment of HPV infection in men can effectively reduce the risk of HPV infection in their partners. In most countries the HPV vaccination coverage among females is far lower than targeting expectation, and the effective herd immunity has not been achieved yet. Men can directly benefit from HPV vaccination, which is also beneficial for their partners, therefore HPV vaccination for men is worth considering. In this article we briefly describe HPV vaccination in males and overview their awareness and acceptance of HPV vaccination, so as to provide references for promoting HPV vaccination among men in the future.

Molecular characterization of Staphylococcus aureus ST6 and ST7 isolates from food-borne illness outbreaks / 中华预防医学杂志

Objective: To analyze the Staphylococcal enterotoxins, Staphylococcal enterotoxin genes, drug resistance and molecular typing of 41 Staphylococcus aureus isolates from 2 food-borne illness outbreaks on 21 August and 27 September 2020 in Guangzhou. Methods: A total of 41 Staphylococcus aureus isolates from 2 outbreaks were analyzed by multilocus sequence typing (MLST) and spa typing. The Staphylococcal enterotoxins typing and the Staphylococcal enterotoxin genes of the isolates were analyzed by ELISA and PCR, respectively. The antimicrobial susceptibility of the isolates was performed by disc diffusion. 21 Staphylococcus aureus isolates were characterized using whole genome sequencing (WGS). Based on the whole genome single nucleotide polymorphism (SNP), the phylogenetic tree was constructed by Snippy. Results: 41 Staphylococcus aureus isolates were divided into 2 types by MLST and spa typing: ST6-t701 and ST7-t091. 2 ST7-t091 isolates were identified as methicillin-resistant Staphylococcus aureus (MRSA). 25 ST7-t091 isolates and 14 ST6-t701 isolates were methicillin-sensitive Staphylococcus aureus (MSSA), and were resistant to 7 and 6 antibiotics, respectively. All isolates were positive for sea by PCR. WGS revealed all 21 isolates carried scn, sak, sea, hla, hld, hlgA, hlgB, hlgC, lukD virulence genes. The results showed the isolates contained an immune evasion cluster type D which located in bacteriophage ϕSa3. The SNP phylogenetic tree showed 2 MRSA ST7-t091 were constituted a separate clade from the 12 MSSA ST7-t091 isolates and 7 ST6-t701 isolates showed high similarity to each other. Conclusion: Base on the results of phylogenetic analysis, the 2 food-borne illness outbreaks occurred on 21 August and 27 September 2020 are caused by the combination of the MRSA ST7-t091 strain and the MSSA ST7-t091 strain, and the MSSA ST6-t701 strain, respectively. All isolates have high level of antibiotic resistance and carry high virulent genes.

lncRNA TPTEP1 affects the proliferation and invasion of bladder cancer T24 cells by inhibiting miR-129-5p / 中国肿瘤生物治疗杂志

@#[Abstract] Objective: To observe the expression of long-chain non-coding RNA (lncRNA) TPTEP1 in bladder cancer tissues and cells, and to observe its effect on the proliferation and invasion of bladder cancer cells and its molecular mechanism. Methods: From August 2017 to October 2019, 43 cases of bladder cancer tissues and paracancer tissues from the patients treated by surgery in the Department Urology, People's Hospital of Dongxihu Distric of Wuhan City. Real-time fluorescence quantitative polymerase chain reaction (qPCR) was used to detect the expression of lncRNA TPTEP1 in bladder cancer tissues and bladder cancer cell lines (T24, BIU-87, 5637, J82, UM-UC-3). The bladder cancer cells with the lowest lncRNA TPTEP1 expression were selected as the experimental object, and transfected with the negative control plasmid (the control group) and lncRNA TPTEP1 over-expression plasmid (the experimental group), respectively. The effect of lncRNA TPTEP1 upregulation on cell proliferation and invasion was detected by MTT method and Transwell experiment. Bioinformatics techniques were used to predict the possible target molecules of lncRNA TPTEP1. qPCR and WB were used to detect the expression levels of lncRNA TPTEP1 downstream molecules. Results: Compared with adjacent tissues, the expression of lncRNA TPTEP1 in bladder cancer tissues was down-regulated (P<0.01). Compared with normal bladder epithelial cells, the expression of lncRNA TPTEP1 in bladder cancer cell lines was down-regulated (P<0.05), and its expression in T24 cells was the lowest (P<0.01). Up-regulation of lncRNA TPTEP1 could inhibit the proliferation (P<0.05) and invasion (P<0.01) of T24 cells. Bioinformatics technology showed that lncRNA TPTEP1 could bind with miR-129-5p, and miR-129-5p could bind with EMP3; up-regulating lncRNA TPTEP1 could inhibit the expression of miR-129-5p in T24 cells (P<0.01), and indirectly promote the mRNA and protein expressions of EMP3 (P<0.01) in T24 cells. The expression of MAPK/ERK signaling pathway related proteins such as p-MEK, p-ERK1/2, p-AKT and p-PI3K decreased (P<0.01). Conclusion: Up-regulating the low-expressed lncRNA TPTEP1 in bladder cancer cell lines can inhibit the proliferation and invasion of bladder cancer T24 cells, and its mechanism is related to indirect promotion of EMP3 gene expression by down-regulating the expression of miR-129-5p.

Efficacy of jejunostomy combined with Ivor-Lewis or McKeown operation in the treatment of middle and lower esophageal cancer: A retrospective cohort study / 中国胸心血管外科临床杂志

@#Objective    To investigate the effect of jejunostomy combined with Ivor-Lewis or McKeown operation on the treatment of middle and lower esophageal cancer. Methods    The clinical data of 127 patients with middle and lower esophageal cancer admitted to our hospital from June 2018 to October 2019 were retrospectively analyzed, including 89 males and 38 females, aged 62.82±8.65 years. The patients were divided into an Ivor-Lewis group (IL group, 72 patients) and a McKeown group (MK group, 55 patients) according to surgical methods. Patients in the IL group received jejunostomy combined with Ivor-Lewis operation, and patients in the MK group received jejunostomy combined with McKeown operation. The operation time, postoperative bedside electrical impedance tomography (EIT) parameters, postoperative inflammatory factor levels, postoperative complications and rehabilitation of the two groups were compared. Results    The operation time (262.65±49.78 min vs. 303.04±60.13 min), postoperative eating time (10.54±2.22 d vs. 11.47±2.49 d) and postoperative hospital stay (14.78±2.47 d vs.15.72±2.36 d) in the IL group were significantly shorter than those in the MK group (P<0.05). The blood loss (156.13±52.43 mL vs. 158.87±48.47 mL) and the number of lymph node dissection (29.47±8.88 vs. 30.17±9.80) in the IL group were less than those in the MK group, but the differences were not statistically significant (P>0.05). The repeated measurement analysis of variance showed that the time point could significantly affect tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and IL-8 levels (Ftime point=520.543, 272.379, 147.688, all P<0.05), but the surgical methods and the interactive effect of time point and surgical methods did not affect the levels of TNF-α, IL-6 and IL-8 (P>0.05). Postoperative bedside EIT image parameters were statistically different on the postoperative 1 d, 3 d, 5 d and 7 d between the two groups (P<0.05). Compared with the MK group, the incidences of recurrent laryngeal nerve injury, arrhythmia, pulmonary infection and atelectasis, anastomotic leakage, gastric wall necrosis and stump fistula, secondary thoracotomy and abdominal hemostasis, and intestinal obstruction were lower, but the differences were not statistically different (P>0.05). The recurrence rate of patients in the IL group within 6 months was lower than that in the MK group, but the difference was not statistically significant (8.33% vs. 9.09%, P>0.05). Conclusion    Jejunostomy combined with Ivor-Lewis or McKeown surgery have equivalent effects on patients with middle and lower esophageal cancer.
