Objective:To investigate the safety and efficacy of submucous radiofrequency ablation of the inferior turbinate, and to provide a clinical basis for the surgical treatment of allergic rhinitis in children. Methods:Patients with obstructive sleep apnea syndrome and allergic rhinitis who were admitted to the Department of Otolaryngology Head and Neck Surgery of Shanghai Children's Hospital from January 2021 to December 2023 and underwent bilateral submucous radiofrequency ablation of the inferior turbinate and radiofrequency ablation of the adenoid tonsil were included in the study. Observational and statistical indexes were used to evaluate the curative effect. Results:A total of 51 cases were included in this study, and 43 cases were followed up for half a year. Submucous radiofrequency ablation of the inferior turbinate plus radiofrequency ablation of the adenoid tonsil achieved a good effect （total effective rate 93%）, and there was a statistically significant difference in the preoperative and postoperative symptoms of the children（P<0.05）. There were no complications such as bleeding, Eustachian tube injury, nasal adhesion, or nasal dryness. Conclusion:Under the premise of strict control of surgical indications, children with allergic rhinitis can be treated surgically. Inferior turbinate submucous radiofrequency ablation is more minimally invasive, effective, and safe, and can be used in clinical practice.

Objective:To understand the use of post-exposure prophylaxis (PEP) and analyze related factors among men who have sex with men (MSM) in Qingdao, and provide a reference for the AIDS prevention and control in this population.Methods:A cross-sectional survey conducted from April 2022 to February 2023. Relying on MSM social groups in Qingdao, a snowball sampling method was applied to recruit research subjects who met the inclusion criteria of age ≥18 years old, having had homosexual anal or oral sex in the past six months, and HIV-negative or infection status unknown. The sample size was estimated at 566. Data on demographic characteristics, sexual behavior characteristics, PEP use, and others of the research subjects was collected through on-site questionnaires. The logistic regression model was used to analyze the factors associated with using PEP.Results:A total of 811 participants were recruited, mainly aged 25-34 (53.6%, 435/811), unmarried (74.7%, 606/811), with an average monthly income of ≥5 000 yuan (52.2%, 423/811), and having lived in Qingdao for ≥10 years (75.6%, 613/811). The proportion of those who knew the HIV status of their sexual partners in the last six months was 67.1% (544/811), and those with HIV-positive partners were 3.6% (29/811). In the last six months, the proportion of participants who had group sex (86.4%, 701/811), unprotected anal sex (98.2%, 796/811), and use of club drugs (80.3%, 651/811) was high. Moreover, 28.4% (230/811) had used PEP. The multivariate logistic regression analysis showed that the factors related to the use of PEP included divorced or widowed (a OR=5.46,95% CI:1.96-15.17), average monthly income ≥5 000 yuan (a OR=2.04,95% CI:1.44-2.89), same-sex sexual orientation (a OR=0.40,95% CI:0.22-0.71), having HIV-positive sexual partners in the last six months (a OR=2.54,95% CI:1.13-5.71) and having been tested for HIV ≥3 times in the last six months (a OR=1.46,95% CI:1.04-2.06). Conclusions:The prevalence of risk behaviors among MSM in Qingdao was high, and the use of PEP was low. In the future, it is essential to increase HIV/AIDS prevention education among MSM, promote MSM to know the HIV status of their sexual partners, and reduce the prevalence of risk behaviors among this population. Additionally, explore medical insurance reimbursement plans for PEP to reduce utilization costs and promote the use of PEP by MSM after HIV exposure occurs as soon as possible.

Objective:To detect the pathogen and clinically diagnose for a suspected case of Neisseria meningitidis with positive blood culture result, and assess the risk of disease transmission among the community. Methods:Blood sample was collected for Neisseria meningitidis isolation and culture. Pathogen identification and serogroup typing were conducted by colony morphology, Gram staining, biochemical tests, latex agglutination test, slide agglutination test, and nucleic acid testing. The susceptibility to 12 antibiotics was also tested. Epidemiological investigation was conducted on the case, and epidemic control measures were also implemented. Results:Through various detection, the suspected case was diagnosed as Neisseria meningitidis invasive infection. The isolated strain belonged to group Y serotype, type 767 (multilocus sequence typing), and the ST167 clonal complex. The strain was sensitive to nine antibiotics, including penicillin, ampicillin, and meropenem. It exhibited intermediate sensitivity to ciprofloxacin and levofloxacin, and resistance to methicillin/sulfamethoxazole. Close contacts of the case and environmental testing results were negative. Conclusions:The case is confirmed to be an invasive infection caused by group Y Neisseria meningitidis, the ST167 clonal complex. Epidemiological investigation shows a relatively low risk of epidemic transmission. Continuous monitoring and surveillance are necessary for further assessment.

Objective:To compare the chemical composition of decoction and granules of Sangju Decoction; To provide a method for quality evaluation of Sangju Decoction.Methods:HPLC was used to establish fingerprints, and a comprehensive comparative study was conducted on the traditional decoction and formula granules of Sangju Decoction from four aspects: chemical composition type, fingerprint similarity, chemical pattern recognition analysis, and representative index component content.Results:The fingerprint similarity of the 10 batches of traditional decoction was >0.988. 35 peaks were identified and 12 peaks were identified as common peaks (neochlorogenic acid for peak 7, chlorogenic acid for peak 10, cryptochlorogenic acid for peak 11, 1,3-dicaffeoylquinic acid for peak 13, rutin for peak 17, lenoside A for peak 19, lignan for peak 20, isochlorogenic acid B for peak 24, ammonium glycyrrhizate for peak 25). The fingerprint similarity of the formulation pellets was >0.983, and 29 characteristic peaks were identified. Compared with the traditional decoction, some batches of the granules lacked peaks 14, 26, 27, 30, 32 and 34, and clustering analysis (CA), principal component analysis (PCA), and orthogonal partial least squares discriminant analysis (OPLS-DA) could distinguish between the two. The contents of the 10 index components neochlorogenic acid, chlorogenic acid, cryptochlorogenic acid, 1,3-dicaffeoylquinic acid, forsythia ester glycoside A, grass glycosides, isochlorogenic acid B, 3,5-O-dicaffeoylquinic acid, forsythia glycosides, monkshood glycosides in the traditional soup were higher than that in the granules, and the contents of rutin and ammonium glycyrrhizate in the granules were higher than that in traditional decoction.Conclusions:The content and composition of traditional decoction and formula granules of Sangju Decoction are significantly different. The combination of fingerprinting and chemical pattern identification effectively can effectively evaluate the difference between traditional decoction and formula granules of Sangju Decoction, which can lay a foundation for the quality control and rational clinical application of formula granules of Sangju Decoction.

OBJECTIVE:Knee adduction moment and knee adduction angular impulse enlargement is the main biomechanical risk factor of knee osteoarthritis.According to the survey,a change in the foot progression angle could effectively change the motion mode of patients with knee osteoarthritis.However,the impact of toe-in and toe-out on knee adduction moment and knee adduction angular impulse in young and elderly patients did not reach a consensus.Therefore,this study comprehensively discussed the effect of foot progression angle on knee adduction moment and knee adduction angular impulse in different populations through meta-analysis and provided a reference for the treatment of knee osteoarthritis. METHODS:By June 2022,searches were conducted on Web of Science,EBSCO,PubMed and CNKI databases using"foot progression angle,knee adduction moment,knee adduction angular impulse,gait"as Chinese and English search terms.Self-controlled randomized controlled studies analyzing the effects of toe-in and toe-out on knee adduction moment bimodality and knee adduction angular impulse were included.The cochrane bias risk assessment tool was utilized to make a quality evaluation of the literature.Stata 15.1 software was used for subgroup analysis to determine the effect of foot progression angle on knee adduction moment and knee adduction angular impulse.Meta-regression analysis was used to further determine characteristics of outcome indicators(knee adduction moment,knee adduction angular impulse)changing with foot progression angle. RESULTS:(1)A total of 15 self-control trials and 2 randomized controlled trials(455 subjects)were included in the meta-analysis.All of the included articles were of medium to high quality.(2)The meta-analysis results showed that the toe-in gait could reduce the first peak of knee adduction moment(SMD=-0.380,95%CI:-0.710 to-0.060,P=0.022)and knee adduction angular impulse(SMD=-1.470,95%CI:-2.160 to-0.770,P<0.001)in young patients.The toe-out gait reduced the second peak of knee adduction moment(SMD=-0.720,95%CI:-1.010 to-1.440,P<0.001)in young patients.In addition,toe-in gait could reduce the first peak of knee adduction moment in elder patients(SMD=-0.550,95%CI:-0.800 to-0.300,P<0.001),but increase the second peak knee adduction moment of elderly(SMD=0.280,95%CI:-0.010 to 0.560,P=0.047).The toe-out gait could decrease the second peak knee adduction moment in this population(SMD=-0.510,95%CI:-0.830 to-0.190,P=0.002).(3)Meta-regression showed that the greater the toe-out in elderly patients,the lower the second peak knee adduction moment. CONCLUSION:(1)Toe-in reduced the first peak knee adduction moment and knee adduction angular impulse in young knee osteoarthritis patients aged 18 to 34 years.Since knee adduction moment and knee adduction angular impulse were associated with medial knee loading and knee osteoarthritis incidence,toe-in gait intervention may be a suitable rehabilitation strategy for young patients.(2)Toe-in increased the second peak of knee adduction moment in older knee osteoarthritis patients over 60 years of age,which may exacerbate knee osteoarthritis in this population.However,the second peak of knee adduction moment during walking in this population decreases as the toe-out increases,contributing to a reduction in medial knee loading,suggesting that older patients may consider using toe-out gait during walking.

Objective:To retrospectively analyze clinical characteristics and treatment of pemphigus/bullous pemphigoid (BP) complicated by herpes simplex virus (HSV) infection.Methods:Inpatients with pemphigus/BP complicated by HSV infection were collected from Wuhan No.1 Hospital from 2016 to 2021, and their clinical characteristics, treatment and follow-up results were retrospectively analyzed.Results:Among the 8 patients with pemphigus/BP complicated by HSV infection, there were 2 males and 6 females, and their age was 50.6 ± 8.3 years. Five of them were diagnosed with pemphigus vulgaris (PV), 1 with pemphigus foliaceus (PF), and 2 with BP. Seven were infected with HSV-1, and 1 with HSV-2. All the 8 patients were given systemic glucocorticoids and immunosuppressive agents for the treatment of pemphigus or BP, and were admitted to the hospital due to resistance to the treatment. Seven patients presented with exacerbation or recurrence of primary lesions, and 1 presented with enlarged lesions all over the body. HSV infection-induced lesions were located on the trunk in 4 cases, on the oral mucosa in 4, on the scalp in 3, and on the face in 2; lesions mainly manifested as irregular erosions with blood crusts, and some centrally umbilicated pustules; 7 patients had obvious pain at the lesional sites. During HSV infection, anti-desmoglein 1 antibody levels decreased in all the 6 patients with pemphigus, and anti-desmoglein 3 antibody levels decreased in 4 of the 5 patients with pemphigus vulgaris; anti-BP180 antibody levels decreased in 1 patient with BP, but increased in the other one with BP. After antiviral therapy at adequate doses for adequate durations (7- to 14-day treatment with valacyclovir alone or in combination with ganciclovir), HSV infection was controlled, the autoimmune bullous skin disorder intensity scores decreased compared with those before the antiviral therapy, and pain was significantly relieved in all the patients. No dose adjustment of glucocorticoids or other immunosuppressive agents was made during antiviral therapy in all patients.Conclusion:HSV infection should be considered when patients with pemphigus/BP suffer from recurrence or exacerbation and poorly respond to conventional treatment; for patients with pemphigus/BP complicated by HSV infection, systemic antiviral therapy at adequate doses can be used to control the disease condition without modifying the conventional immunosuppressive regimen.

Objective:To explore the possible mechanism of Bupiwei Xieyinhuo Shengyang Prescription on gastroesophageal reflux disease (GERD) based on network pharmacology and molecular docking technology.Methods:The main active components and target information of Bupiwei Xieyinhuo Shengyang Prescription were screened by TCMSP database, and targets were identified by GeneCards, OMIM, TTD and PharmGKB databases. The intersection of active ingredient components and disease targets was selected to construct PPI network by STRING. Cytoscape CytoNCA plug-in was used to extract core targets for analysis. GO function enrichment and KEGG pathway enrichment analysis were performed using Metascape. Cytoscape 3.7.2 was used to construct the "component-target-signal pathway" network, and Autodock was used to complete molecular docking verification. Animal experiments were further used for verification. SPF SD male rats were selected and GERD model was established by esophageal stent implantation. After 14 days of intervention, serum TNF-α and COX-2 levels of rats in each group were detected for verification.Results:A total of 215 effective compounds were screened from Bupiwei Xieyinhuo Shengyang Prescription. The main targets of GERD were TNF, IL6, CASP3, TP53 and PTGS2, which mainly focused on cancer pathway, AGE-RAGE signaling pathway, calcium signaling pathway and NF-κB signaling pathway. The results of molecular docking showed that the binding potential and activity of the key active components of Bupiwei Xieyinhuo Shengyang Prescription and the core target were better. Compared with the model group, Bupiwei Xieyinhuo Shengyang Prescription could reduce the serum expression levels of TNF-α and COX-2 ( P<0.01). Conclusions:By regulating TNF, IL6, CASP3, TP53, PTGS2 and other core targets, Bupiwei Xieyinhuo Shengyang Prescription can regulate NF-κB signaling pathway, calcium signaling pathway and other signaling pathways to play a role in the treatment of GERD.

Objectives:To understand the use of pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP) and related factors in men who have sex with men (MSM) in Shandong Province, and provide reference for the promotion of PrEP and PEP in MSM.Methods:From April to July in 2022, MSM were recruited from 7 sentinel surveillance sites in Shandong Province for a questionnaire survey, and the sample size of each city site was 400. The information about sociodemographic characteristics, sexual behaviors, the uses of PrEP and PEP and others were collected from the MSM, and blood samples were collected from them for HIV and syphilis testing.Results:A total of 2 815 MSM were investigated, the majority of them were aged less than 30 years (55.7%, 1 569/2 815), unmarried (68.6%, 1 931/2 815) and had education background of college and above (56.5%, 1 590/2 815). Only 9.2% (258/2 815) had used PrEP and 10.8% (305/2 815) had used PEP. Multivariate logistic regression showed that factors associated with high likelihood of PrEP use in MSM included age ≤30 years (a OR=4.04, 95% CI:1.25-13.01), self-perceived lower risk of HIV infection (a OR=1.76, 95% CI:1.16-2.68), group sex and commercial sex in the past six months (a OR=1.51, 95% CI: 1.10-2.09; a OR=1.69, 95% CI: 1.16-2.47), new-type drug use (a OR=1.53, 95% CI: 1.11-2.11), receiving peer education (a OR=1.56, 95% CI: 1.03-2.37), other people using PrEP (a OR=3.29, 95% CI: 2.48-4.36), and being HIV negative (a OR=8.40, 95% CI:1.12-63.12). Factor associated with low likelihood of PrEP use in MSM was anal sex with casual partner (a OR=0.67, 95% CI:0.49-0.90). Factors associated with high likelihood of PEP use in MSM included age under 50 years (≤30 years old: a OR=2.41, 95% CI:1.02-5.69; 31-49 years old: a OR=3.33, 95% CI:1.42-7.85), no self-perceived risk for HIV infection (a OR=1.87, 95% CI:1.12-3.11), group sex in the past six months (a OR=1.68, 95% CI:1.23-2.29), new-type drug use (a OR=3.86, 95% CI:2.94-5.07) and receiving no peer education (a OR=1.54, 95% CI:1.12-2.12). Conclusions:In Shandong, a higher proportion of MSM used PrEP and PEP. Peer education and self-perceived HIV infection risk education should be strengthened to increase the rates of PrEP and PEP use in MSM.

Objective:To explore the influencing factors of AIDS-related deaths among HIV-infected patients in Shandong Province, to help reduce the risk of death and prolong survival time.Methods:The study population was HIV-infected patients in Shandong Province from 2017-2021, and Cox proportional hazards regression model was used to analyze the influencing factors of AIDS-related deaths and deaths within one year of confirmation.Results:Among 14 700 HIV- infected patients reported in Shandong Province in 2017-2021, 351 AIDS-related deaths occurred, accounting for 2.4% (351/14 700). The results of multifactorial Cox proportional hazards regression model analysis showed that the risk factors for AIDS-related deaths among HIV-infected patients included education level of junior high school, high school, and secondary school (a HR=1.37, 95% CI:1.01-1.84), sample source from healthcare institutions (a HR=1.61, 95% CI:1.22-2.12), duration of disease in AIDS stage (a HR=9.86,95% CI:6.86-14.19), baseline CD4 +T lymphocytes (CD4) undetected (a HR=3.93, 95% CI:2.69-5.75), duration of antiviral treatment (ART) <6 months (a HR=3.46, 95% CI:2.42-4.93) and no ART (a HR=1.45, 95% CI:1.02-2.07), final CD4 <200 cells/μl (a HR=3.51, 95% CI:2.18-5.65) and final CD4 undetected (a HR=10.58, 95% CI:6.15-18.19), and final viral load (VL) values of 50-999 copies/ml,≥1 000 copies/ml and undetected (a HR=2.59, 95% CI:1.07-6.26; a HR=9.50, 95% CI:5.60-16.12; a HR=15.33, 95% CI:8.91-26.36). Factors with higher risk of AIDS-related deaths within one year of confirmation of HIV-infected patients included samples originating from healthcare facilities (a HR=1.68, 95% CI: 1.19-2.36), AIDS stage of disease (a HR=10.60, 95% CI:7.13-15.75), baseline CD4 undetected (a HR=3.71, 95% CI:2.34-5.90), duration of ART <6 months (a HR=4.30, 95% CI:2.85-6.49) and no ART (a HR=2.05, 95% CI:1.35-3.13), final CD4 <200 cells/μl (a HR=5.45,95% CI:2.04-14.60) and final CD4 undetected (a HR=20.95, 95% CI: 7.69- 57.04), and final VL values of 50-999 copies/ml, ≥1 000 copies/ml and undetected (a HR=15.21, 95% CI: 2.54-91.21; a HR=42.93, 95% CI:9.64-191.20; a HR=61.35, 95% CI:13.85-271.77). Conclusions:Expanding the coverage of testing, promoting early detection and treatment, strengthening regular follow-up and the test of HIV-infected patients, grasping the progress of the disease to provide accurate management and treatment are important for reducing the disease mortality rate and prolonging the survival time of HIV-infected patients.
