Objective To analyze the nucleotide sequences and genetic polymorphisms of UL138 gene of low passage human cytomegalovirus ( HCMV) strains isolated from infants in Guangzhou province. Methods The low passage strains of HCMV were isolated from urine samples of 10 infants with HCMV in-fection in Guangzhou province and identified by multiplex PCR.The UL138 genes were amplified, cloned and identified with sequencing.The sequences were analyzed together with the homologous sequences of 10 clinical isolates published in GenBank.The sequences of UL138 genes were analyzed by using bioinformatics softwares for investigation of the post-translational modification sites, isoelectric points and second structures of UL138 proteins.Results Three low passage strains of HCMV ( D2, D3 and D52) were isolated from in-fants with congenital HCMV infection.The complete sequences of UL138 genes of the three strains were sub-mitted to GenBank after sequencing identification with the GenBank accession numbers of DQ180375, DQ180387 and DQ180359, respectively.The UL138 gene sequences of the three clinical isolates were high-ly conservative.Among the 841 base pairs of the UL138 gene sequences, mutations were identified in 16 sites with base substitution, no any insertion and deletion mutation was found.The 16 mutations resulted in 7 amino acid changes.No additional or deleted sites were found with regard to the post translational modifi-cation sites of UL138 protein in all clinical isolates except the Toledo strain.The isoelectric point of UL138 protein was 6.51 for all clinical isolates.Conclusion The UL138 genes and the deduced amino acid se-quences of HCMV strains isolated from infants in Guangzhou were highly conservative, regardless of the poly-morphism of UL138 gene.This study paved the way for further investigation on HCMV infection and its path-ogenic mechanism.

Background: Anal fissure is one of the most common anal-rectum diseases, and approximately 10 percent patients with chronic anal fissure ultimately receive surgery. Relieving postoperative pain and protecting functions of the sphincter are central issues for coloproctologists. Objective: To evaluate the efficacy and safety of anoplasty in the treatment of chronic anal fissures. Design, setting, participants and interventions: In this prospective, multicenter, randomized controlled trial, 120 adult patients with chronic anal fissure were referred from Department of Coloproctology of Yueyang Hospital of Integrated Traditional Chinese Medicine Affiliated to Shanghai University of Traditional Chinese Medicine, Shanghai Ninth People's Hospital Affiliated to Shanghai Jiao Tong University School of Medicine and Shanghai Municipal Hospital of Traditional Chinese Medicine. The patients were enrolled from January 2009 to April 2010 and randomly divided into study (mucosa advancement flap anoplasty, abbreviated as anoplasty) group and control (fissurectomy) group. The two groups were assessed separately, and the main outcome measures were observed for 2 weeks, with a short-term follow-up for 6 weeks. Main outcome measures: Degree of pain, haemorrhage and anal canal pressure were observed and recorded preoperatively, and on the third day, the fourteenth day and the sixth week postoperatively. The wound healing time was also recorded. Surgical complications of the two groups were recorded and compared on the third day and the sixth week postoperatively. The curative effects associated with the surgery were analyzed on the fourteenth day and the sixth week after surgery and the therapeutic results were evaluated. Results: Three patients were dropped out due to the early discharge from hospital and losing connection (1 in study group and 2 in control group). Overall the surgery showed that the anoplasty group had better results than the fissurectomy group in the curative effect on the sixth week after operation (P<0.05). Time of wound healing in the anoplasty group was (17.22±4.41) d and was better than (21.24±7.44) d of the fissurectomy group (P<0.05). Concerning the relief of wound pain, the anoplasty group achieved better results than the fissurectomy group at the third day, the fourteenth day and the sixth week after operation (P<0.05). Anoplasty reduced bleeding and had better efficacy than the fissurectomy at the third day and the fourteenth day after operation (P<0.05), however, there was no statistical difference at the sixth week after operation (P>0.05). There were no significant differences in relieving the anal canal pressure (P>0.05) and the surgical complications (dysuria, edema of anal margin, fever, infection, anal incontinence and anal deformation) between the two groups (P>0.05). None of the patients suffered postoperative complications by the sixth week after operation. Furthermore, there was no recurrence in either of the two groups at six weeks after operation. Conclusion: The results indicate that anoplasty for chronic anal fissures has advantages such as better therapeutic effects, less postoperative pain, a shorter healing time and no incidence of anal incontinence.

Objective:To construct the concept and its conceptual framework of hospital health literacy(HHL) for exploring the HHL promotion mechanism in the country.Methods:Based on the proceduralised grounded theory, twelve middle or senior managers of hospitals were selected for in-depth interviews and three hospitals were selected for field research from July 2021 to February 2022. Open coding, axial coding, and selective coding were used in data analysis, establishing the concept of HHL and its conceptual framework in China.Results:The conceptual framework of HHL was composed of an internal driver mechanism(hospitals improve their health literacy promotion management system, staff-led health literacy promotion, health literacy promoting physical environment construction), and an external driver mechanism(cooperate with external organizations and institutions to conduct health literacy promotion). The concept of HHL in China was derived as follows: the combination of supportive environments and human resources that health care organizations have in place can improve access and understandability of health information and simplify healthcare services to help patients of different health literacy levels more easily obtain, process, and understand health information as well as to make the most of medical services.Conclusions:Hospital health literacy promotion mechanism in China is a synergy between internal and external driver mechanisms.

Radiation induced lung injury (RILI) is a serious complication in patients received thoracic radiotherapy. The main clinical symptom of RILI includes short of breath, low fever and cough, seriously affect the survival of patients. How to better prevent and treat RILI is an urgent problem. Target theory, cytokine theory, free radical theory, and vascular endothelial cell damage theory are the main mechanisms of RILI. Among them, reactive oxygen species (ROS) produced during radiotherapy can induce tissue damage throughout the course of RILI, and have a direct effect on both radiation pneumonitis and radiation-induced lung fibrosis. Anti-oxygen therapy including thiol compounds, antioxidant enzymes, and plant antioxidants have been applied in the prevention and treatment of RILI. This article reviews the research and application of antioxidant therapy in RILI.
