Objective To investigate the relationship between different interleukins (ILs) and gynecological tumors, including cervical cancer, endometrial cancer, and uterine leiomyoma using two-sample Mendelian randomization (MR) analysis. Methods IL and gynecological tumor data were obtained from European populations by using the IEU OpenGWAS open database. Two-sample MR analysis was applied, different interleukins were used as exposure factors, significant SNP in GWAS data were selected as instrumental variables, and the instrumental variables were independent of each other. The risk of three kinds of gynecological tumors was analyzed separately to explore the causal relationship between ILs predicted by genes and outcome indicators. The TwoSampleMR package in R language (4.3.1) software was used for statistical analysis. MR analysis was performed using inverse variance weighted, MR Egger regression, weighted median, simple mode, and weighted mode methods. Results IL-18 receptor 1 (P=0.039) and IL-24 (P=0.025) were negatively correlated with the risk of cervical cancer. IL-4 (P=0.040), IL-21 (P=0.026), and IL-37 (P=0.027) were positively correlated with the risk of endometrial cancer. IL-15 receptor subunit alpha (P=0.005) was negatively correlated with the risk of endometrial cancer. IL-17A (P=0.005) and IL-37 (P=0.018) were negatively correlated with the risk of uterine leiomyoma. IL-21 (P=0.035) was positively correlated with the risk of uterine leiomyoma. Conclusion Genetically predicted IL-4, IL-15Rα, IL-17A, IL-18R1, IL-21, IL-24, and IL-37 are causally associated with the risk of three gynecological tumors. Further exploration of the molecular mechanism of ILs in gynecological tumors may provide potential therapeutic targets for the treatment of gynecological tumors.

BACKGROUND:The key to preventing the recurrence of intrauterine adhesions is to reconstruct the endometrium with normal function.The latest breakthrough in the treatment of recurrent intrauterine adhesions in and outside China is the use of degradable materials to prepare hydrogels to prevent the recurrence of adhesions. OBJECTIVE:To review the research advance in hydrogel-promoted endometrial repair in intrauterine adhesions. METHODS:PubMed,Web of Science,China National Knowledge Infrastructure(CNKI),and WanFang databases were searched systematically,with the keywords"intrauterine adhesions,endometrial injury,endometrium regeneration,hydrogel"in Chinese and English.Relevant articles published in each database from January 1990 to March 2023 were collected. RESULTS AND CONCLUSION:In recent years,research on hydrogel-promoted endometrial repair in uterine adhesions in and outside China has made some progress and plays an important role in the prevention and treatment of intrauterine adhesions and the promotion of endometrial repair:(1)As an important carrier in tissue engineering,hydrogel itself has excellent biocompatibility,biodegradability and three-dimensional network structure,which can be better applied in the treatment of intrauterine adhesions.(2)The hydrogel-based carrier system can promote the proliferation and differentiation of endometrial epithelial cells by transporting drugs/biologics/stem cells,and restore normal uterine morphology to prevent adhesion recurrence.(3)Hyaluronic acid hydrogels can not only meet good biocompatibility,but also promote the proliferation and differentiation of endometrial epithelial cells,and will be hydrolyzed by corresponding enzymes in utero,without affecting the normal metabolism of the body.They are currently commonly used uterine anti-adhesion agents in the clinic and are also the most commonly used hydrogel carriers in tissue engineering research.(4)Poloxamer hydrogel with excellent temperature-sensitive properties can rapidly gelate into the body,quickly form a physical barrier,and can play a slow-release effect on carrying substances and provide a platform for cell growth/adhesion.(5)There are broad prospects for the preparation of therapeutic hydrogels using materials with different characteristics,such as temperature-sensitive hydrogels,pH-responsive hydrogels and photosensitive hydrogels,but there are still many problems to be solved,such as the safety of the hydrogel system,whether the degradation products cause immune reactions,and whether they have an impact on the normal body's menstrual period.A large number of animal experiments and clinical trials are needed to verify its safety and efficacy,and continuously improve the treatment strategy.

Objective:To explore the clinical application and effect of FilmArray ? meningitis/encephalitis (ME) panel in identifying pathogens of central nervous system (CNS) infections in children. Methods:Molecular biology study.Cerebrospinal fluid (CSF) samples were prospectively obtained through lumbar puncture from children with suspected CNS infections admitted to the Department of Infectious Diseases at Beijing Children′s Hospital, Capital Medical University from May to November 2019.These samples were subjected to both routine clinical pathogen testing and FilmArray ME panel testing.Polymerase chain reaction was used to validate all samples.Independent sample t-test or Mann-Whitney U-test was used for comparative analysis of the results and influence factors obtained by the two detection methods. Results:A total of 113 cases of suspected CNS infections were enrolled.Routine clinical testing yielded 17 cases, with a positive rate of 15.0%, including 4 positive CSF cultures, with a positivity rate of 3.5%.FilmArray ME panel detected 23 positive cases, with a positive rate of 20.4%.FilmArray ME panel detected bacteria in 7 cases, viruses in 13 cases, fungi in 1 case, and both viruses and bacteria in 2 cases.Among the common pathogens detected, FilmArray ME panel obtained the results on average 2.7 days in advance.Conclusions:Compared with CSF culture, FilmArray ME panel has the advantages of shorter detection period, higher positive detection rate, and higher virus detection rate.

Berberine is an antipyretic and detoxicating drug commonly used in clinical practice,and it is currently used for the routine treatment of gastrointestinal diseases such as bacterial gastroenteritis and diarrhea.However,several recent studies have shown that berberine can exert a therapeutic effect on the diseases such as autoimmune hepatitis,viral hepatitis,nonalcoholic fatty liver disease,and liver cancer by regulating the AMPK and TGF-β pathways and altering the composition of intestinal flora.This provides new drugs for the treatment of these diseases,expands the potential indications of berberine,and provides clues for the follow-up research and development of similar drugs.This article summarizes the therapeutic effect and mechanism of berberine on various liver diseases,in order to provide a reference for effective clinical application.

Objective:To explore the effectiveness of the comprehensive healthcare management model for children with bacterial meningitis after discharge.Methods:This study was a retrospective cohort study that included 268 children with bacterial meningitis who were discharged from the infectious medicine ward of Beijing Children′s Hospital from September 2018 to September 2023. The children were managed with a multidisciplinary collaborative comprehensive healthcare management model after discharge. Outpatient data at 1 month and 6, 12 and 24 months after discharge were collected, including (height, weight, body mass index, nutritional feeding status, hearing and vision screening results, Gesell developmental assessment results and intervention guidance services. The follow-up interval or frequency was dynamically adjusted or increased according to the child′s situation. The paired sample t-test and chi square test were applied to compare the differences in Gesell developmental quotient (DQ) and developmental delay rate between the first and last assessments to preliminarily explore the effectiveness of the comprehensive healthcare management model for children with bacterial meningitis after discharge. Results:All the 268 children completed their first assessment one month after discharge, and 37 children were found to have abnormal physical growth, mainly obesity (28 children), and another 9 children were malnutrition. Nutritional intervention and feeding guidance services were provided to all the 37 children, and as of the last follow-up, 20 children′s physical growth evaluations had turned normal. A total of 188 children completed at least 2 developmental assessments, with an interval of (14.2±9.4) months between the first and last assessments (range: 3.1-49.5 months). The DQ values of in the energy region of adaptability, gross motor skills, fine motor skills, language, and personal social skills at the last assessment were significantly higher than those at the first assessment [(91.93±13.28) vs (80.73±15.96) points, (91.69±12.96) vs (78.31±16.58) points, (89.32±16.11) vs (80.68±15.63) points, (90.10±16.65) vs (82.04±18.43) points, (92.01±14.05) vs (77.82±17.42) points]; moreover, the rates of developmental delay in each energy region were significantly lower than those at the initial assessment (9.6% vs 35.1%, 9.6% vs 42.0%, 18.1% vs 33.0%, 13.3% vs 31.9%, 9.6% vs 42.0%) (all P<0.05). Among the 200 children who completed the hearing screening, 18 were found with hearing abnormalities, and 2 were diagnosed with hearing loss in the Otolaryngology Department. Among 217 children who completed vision screening, 23 had abnormalities, and 5 were diagnosed with ophthalmic abnormalities in Ophthalmology Department (2 with strabismus, 2 with refractive errors, and 1 with optic nerve injury). Two children were found to have autism-like behavior during monitoring, and were referred to a developmental behavior clinic to be diagnosed with autism spectrum disorder and were given early diagnosis and intervention guidance. Conclusion:The comprehensive healthcare management model for children with bacterial meningitis after discharge can integrate clinical and healthcare resources, which is beneficial for improving the prognosis and enhancing the quality of life for children with special health status.

Recent studies have revealed that intestinal flora and immunity play important roles in the formation of gallstones. This paper reviewed the relationship between the abundance and composition of intestinal flora, immuno - globulins, mucins and immune cells, as well as the interactions between intestinal flora and biliary immunity and gallstone formation for providing new ideas and methods for gallstone prevention and treatment.

【Objective】 To explore the effects of status of lymph vascular invasion (LVI) on the survival of patients with squamous cell carcinoma of the penis (SCCP). 【Methods】 Data of patients diagnosed as SCCP during Jan.1, 2010 and Dec.31, 2019 were extracted from the Surveillance, Epidemiology, and End Results (SEER) database. Kaplan-Meier method was used to draw the survival curve of patients with different LVI statuses, and log-rank test was conducted in parallel. Univariate and multivariate Cox regression analyses were used to assess the effects of LVI status on the overall survival. Patients were divided into different subgroups based on stage (localized, regional, and distant metastasis) and grade (well, moderately and poorly differentiated) of tumor, and the effects of LVI status on the overall survival of patients in different subgroups were assessed. 【Results】 A total of 1 435 patients were involved, including 1 102 (76.8%) without LVI and 333 (23.2%) with LVI. Median survival time of patients without LVI and with LVI were 27.5 months and 17.0 months, respectively (χ²=55.028, P<0.001). Cox regression analyses showed LVI was a significant prognostic factor in SCCP patients (HR=1.280, 95%CI:1.044-1.569, P=0.018). In the subgroup analysis, LVI was an independent risk factor affecting the overall survival of patients with localized tumor (HR=1.446, 95%CI:1.009-2.110, P=0.046) and regional tumor (HR=1.323, 95%CI:1.018-1.720, P=0.036);it was also an independent risk factor affecting the overall survival of SCCP patients with well differentiated tumor (HR=2.797, 95%CI:1.573-4.971, P=0.046) and moderately differentiated tumor (HR=1.431, 95%CI:1.071-1.914, P=0.015). 【Conclusion】 LVI status is a significant factor affecting the prognosis of SCCP patients. LVI is an independent risk factor for the overall survival of SCCP patients with localized and regional tumor, moderately differentiated and well differentiated tumor.

Objective:To examine whether the mixed infection rate in pertussis infants is significantly higher than that in non-pertussis infants with respiratory tract infection, to explore the mixed infection pathogen distribution in pertussis infants, and to provide reference for clinical diagnosis and treatment.Methods:A case-control study was conducted on 118 nasopharyngeal swabs collected from infants who applied for clinical pertussis etiological testing (culture and specific nucleic acid detection of Bordetella pertussis) in Beijing Children′s Hospital, Jiaxing Maternity and Child Health Care Hospital and Wuhu No.1 People′s Hospital from August 2018 to January 2021.According to the pertussis etiological testing results, the patients were divided into the pertussis group (65 cases) and non-pertussis group (53 cases). Thirty-three pairs of cases were matched according to age, onset season and city.All nasopharyngeal swabs were tested for infections of other pathogens using FilmArray RP2, which can detect 21 respiratory infection pathogens.The mixed infection rate was compared between groups by Chi- square test. Results:According to the FilmArray RP2 test results, 56.9%(37/65) cases in pertussis group and 15.1%(8/53) cases in the non-pertussis group were positive for multiple pathogens, and the difference was statistically significant ( χ2=21.651, P<0.001). The top 5 mixed infection pathogens in pertussis infants were human rhinovirus/enterovirus (HRV/EV) (38.5%, 25/65), parainfluenza virus (PIV) (18.5%, 12/65), respiratory syncytial virus (RSV) (10.8%, 7/65), coronavirus (Cov) (10.8%, 7/65), and adenovirus (ADV) (7.7%, 5/65). The mixed infection rates of the pertussis group in spring, summer, autumn and winter were 46.2% (6/13), 58.3%(14/24), 55.6%(5/9), and 63.2%(12/19), respectively.Comparison of matched and unmatched cases achieved similar results. Conclusions:Among clinical suspected pertussis infant specimens, the mixed infection rate in confirmed cases is tremendously higher than that in non-pertussis infants.The main mixed infection pathogens in pertussis infants are HRV/EV, PIV, RSV, Cov, and ADV.Mixed infection in pertussis children commonly occurs in four seasons, with the highest incidence in winter.

Objective:To evaluate the therapeutic effect of one-stage correction of upper eyelid laxity and glabella wrinkle with partial removal of interbrow depressor muscles and filling by autologous dermis.Methods:The clinical data of patients with upper eyelid skin laxity accompanied by prominent dynamic and static glabella wrinkle admitted to the Department of Plastic Surgery, Second Hospital of Nanjing from January 2018 to January 2021 were analyzed retrospectively. The upper eyelid was corrected with under-eyebrow incision or upper eyelid blepharoplasty. The resected skin from laxity was trimmed as autologous dermis for filling of glabellar wrinkle. Meanwhile, the descending brow muscle was also partially resected. All patients were followed up to observe the improvement of dynamic and static glabella wrinkles and related complications.Results:There were 16 cases, including 2 male cases and 14 female cases, aged from 37 to 57 years (mean 47.3 years). Primary healing was achieved in all cases without any hematoma and infection. Follow-up period lasted for 4-13 months. The upper eyelid laxity was corrected with improvement of dynamic and static glabella wrinkle. The patients were satisfied. Needle-like depressed scar happened in one case with no treatment. 1 case had slight prominent tissue between the eyebrows, which was improved by local injection of compound Betamethasone injection 6 months after operation. 2 cases had mild hypoplasia between the eyebrows without treatment. 2 cases had numbness, which was relieved spontaneously after 3 months.Conclusions:One-stage correction of upper eyelid laxity and glabella wrinkle with partial removal of interbrow depressor muscles and filling by autologous dermis can effectively improve periocular aging.
