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: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 summarize clinical manifestations and histopathological features of granular parakeratosis (GP) after exposure to benzalkonium chloride.Methods:A retrospective analysis was performed on 7 GP cases with a history of benzalkonium chloride exposure in the Department of Dermatology at Wuhan No.1 Hospital from April to August 2022. Data were collected on the general condition, skin lesion manifestations, pathological examination, treatment, and follow-up of the patients, and retrospectively analyzed.Results:The 7 adult patients with GP typically presented with erythema and brown scales in the intertriginous area, exhibiting an annular distribution pattern. All the 7 patients reported recent exposure to disinfectants containing benzalkonium chloride. A total of 10 skin biopsies were taken from the 7 patients. Histopathological examination showed characteristic hyperkeratosis and fine blue-gray parakeratotic granules in the stratum corneum. All skin lesions improved 1 month after cessation of exposure to benzalkonium chloride.Conclusion:GP has a distinct clinical pattern and histopathological manifestations, and a history of exposure to benzalkonium chloride can be helpful for the diagnosis of GP.

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.

Objective:To compare the characteristics of MSM with different types of primary sexual partners and to analyze the factors associated with MSM not being tested for HIV in the last six months.Methods:MSM were recruited in nine cities of Shandong Province from April to July 2021, and face-to-face questionnaires were conducted to collect information on sociodemographic characteristics, high-risk behaviors, and HIV testing of MSM. Blood samples were taken for serological tests of HIV and syphilis antibodies.Results:A total of 3 008 men who had anal sex with men in the last six months were divided into three groups according to the type of primary sexual partner in the last six months: the fixed sexual partner group (36.83%, 1 108/3 008), the commercial sexual partner group (3.06%, 92/3 008), and casual sexual partner group (60.11%, 1 808/3 008). There were statistically significant differences in the distribution of age, local residence time, education level, the primary place to find male sexual partners, use of new-type drugs in the last six months, consistent condom use every time during same-sex anal sex in the last six months, group sex in the last six months, no HIV testing in the last six months, having had a sexually transmitted disease in the last year, receiving peer education in the last year, and frequency of syphilis testing in the last year among different groups ( P<0.05). Multivariable logistic regression analysis showed that related factors of not being tested for HIV in the last six months in MSM were those aged less than 30 years old (a OR=1.39, 95% CI: 1.06-1.83), married/cohabiting (a OR=1.74, 95% CI: 1.39-2.16), high school education or less (a OR=1.39, 95% CI: 1.15-1.67), had not used new-type drugs in the last six months (a OR=2.27, 95% CI: 1.89-2.71), had not received peer education in the last year (a OR=1.59, 95% CI: 1.28-1.98), had never been tested for syphilis (a OR=11.30, 95% CI: 8.15-15.66), had not been tested in the last year but had been previously tested for syphilis (a OR=5.65, 95% CI: 4.19-7.62), the type of primary sexual partner in the last six months being a commercial sexual partner (a OR=1.80, 95% CI: 1.01-3.20), and the type of primary sexual partner in the last six months being a casual sexual partner (a OR=1.50, 95% CI: 1.26-1.80). Conclusions:The characteristics of MSM with different types of primary sexual partners are different, and the proportion of HIV testing still needs to be improved. In the future, we should make full use of the Internet and peer education to expand the coverage of HIV testing for MSM, targeting the characteristics of MSM with different types of primary sexual partners.

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.

Objective:To analyze the awareness status and influencing factors of hepatitis C among patients presented to hospitals in Shandong province, to provide reference for the prevention and control of viral hepatitis C.Methods:A total of 22, 139 questionnaires were collected from local residents aged 15-65 who visited general hospitals in 16 cities in Shandong province from May to December 2021. The survey was conducted in the form of face-to-face questionnaires, including general demographic information and questions and answers on hepatitis C prevention, treatment. and related behavioral characteristics. There are a total of 8 questions on the prevention and treatment of hepatitis C, and if 6 questions are correct, it is judged as knowing.Results:The overall awareness rate of hepatitis C-related knowledge among those who visited hospitals in Shandong province was 57.75%. The awareness rate of hepatitis C knowledge among respondents aged less than or equal to 20, 21-40, and 41-59 was higher than that of the age group over 60 years old. The OR values were 1.49, 2.30 and 1.88, respectively; the awareness rate of respondents with education level of high school or junior college and above was higher than that of people with education level of junior high school and below, the OR values were 1.14 and 1.21, respectively; The awareness rate of physical examination population and invasive diagnosis and treatment population was higher than that of family planning clinic visits, with OR values of 1.20 and 1.28, respectively. The awareness rate of respondents with a history of visiting a doctor in an informal medical service was lower than that of the population without such behavior. Conclusions:The awareness rate of hepatitis C knowledge among hospital patients in Shandong province needs to be further improved. Carrying out different forms of publicity and education for different groups of people is an effective means and method to reduce the hepatitis C infection rate.

Objective:To analyze the timeliness and influencing factors of antiretroviral treatment (ART) among HIV/AIDS patients from 2017 to 2019 in Shandong province.Methods:Data were collected from the Chinese HIV/AIDS Comprehensive Response Information Management System, HIV/AIDS cases enrolled in antiretroviral therapy, from January 1, 2017 to December 31, 2019, ≥15 years of age and from the mainland of China were the subjects of the study. The general demographic characteristics (gender, age, ethnicity, education level, marital status, etc), infection routes, sample sources, date of diagnosis, baseline CD4+ T cell level, and clinical stage and other information were collected from the database. Univariate analysis was conducted for the timeliness of ART of the subjects by Chi square test, and the influencing factors associated with timeliness of ART were analyzed by binary non-conditional Logistic regression.Results:Among the 7 425 cases of HIV/AIDS, 6 813(91.8%) were male, 5 236(70.5%) had homosexual transmission, the age at the ART initiation was(36.05±12.51)years. The proportion of timeliness of ART within 30 d increased from 55.9% (1145/2050) in 2017 to 65.3% (1821/2789) in 2019. The possibility of timeliness of ART among HIV/AIDS who were married or cohabiting, education of high school and above were higher, with OR values at 1.136, 1.299. The possibility of timeliness of ART among HIV/AIDS cases whose domicile place is outside Shandong province were lower, with OR values at 0.664. The possibility of timeliness of ART in group of HIV/AIDS aging≥55, 45~54 and 35~44 years old were higher than that in 15~24 years old, with OR values at 1.530, 1.505 and 1.394. The possibility of timeliness of ART among the heterosexuals were lower than that of homosexuals, with OR values at 0.803. The possibility of timeliness of ART is lower for cases in places of detention centers than cases from volunteer testing and counseling, with OR values at 0.204. The possibility of timeliness of ART among HIV/AIDS cases whose CD4+ T lymphocyte at >500 cells/μL were lower than that of the cases whose CD4+ T lymphocyte at≤500 cells/μl, with OR values at 0.545. Patients without symptoms at baseline were less likely to receive prompt treatment than those with clinical symptoms, with OR values at 0.727. Patients with baseline clinical staging of stage Ⅳ, period of HIV/AIDS treatment with timeliness was longer than the cases with baseline clinical stages ofⅠ, Ⅱ, Ⅲ, with OR values at 1.307. Conclusions:The proportion of timeliness of ART increased from 2017 to 2019. Marital status, educational level, age, sample source, infection routes, baseline clinical stage, and CD4+ T lymphocyte levels were associated with the timeliness of ART.

Objective:To understand the driving factors of postpartum health promotion behaviors in pregnant women with gestational diabetes.Methods:From September to October 2019, the purpose of the sampling method was to select 14 cases of gestational diabetic gynaecologists who visited the outpatient department of diabetes care in our hospital as the research subjects. The phenomenological research method was used to conduct a semi-structured interview. Colaizzi′s 7-step analysis method was used to organize and analyze the data to refine the subject.Results:The driving force of postpartum health promotion behaviors of gestational diabetes mothers mainly came from the internal driving force and the external driving force. The internal driving force was mainly the uncertainty of gestational diabetes, the solution of the problem improves self-worth, and the post-traumatic growth made patients re-understand life. The external driving force was mainly family support, full mobilization of subjective initiative, quantitative diet intake and building of a healthy lifestyle.Conclusions:The driving factors for postpartum health promotion of gestational diabetic women are complex and diverse. Medical staff should timely grasp the post-natal health promotion status of gestational diabetic women, and promote their self-support and social support.

Objective:To investigate the clinical curative effect of closed reduction and internal fixation of Jakob type II lateral humeral condyle fractures in children under ultrasound guidance.Methods:A retrospective case series analysis was made on clinical data of 59 patients with Jakob type II lateral humeral condyle fractures treated at Children's Hospital of Chongqing Medical University from August 2016 to August 2017. There were 30 males and 29 females, with the age of 1.5-8.1 years [(4.0±1.8)years]. There were 34 patients treated by open reduction and internal fixation and monitored by the X-ray (control group), and 25 patients treated by closed reduction and internal fixation and monitored by ultrasound (study group). The operation time, bleeding volume, fracture healing time, and incidence of complications were compared between the two groups. The elbow joint function was evaluated by Broberg and Morrey standard at the latest follow-up.Results:All patients were followed up for 17-31 months[(23.2±4.2)months]. The operation time and bleeding volume in control group were (50.7±22.2)minutes and (6.1±3.8)ml, obviously higher than those in study group [(21.4±3.3)minutes, (1.1±0.3)ml] ( P<0.05). The fracture healing time was (8.0±0.8)weeks in control group and (7.8±0.7)weeks in study group ( P>0.05). According to the Broberg and Morrey standard, the good and excellent rate of elbow joint function in control group was 97%, with excellent results in 31 patients, good in 2, fair in 1, and poor in 0; the good and excellent rate of elbow joint function in study group was 100%, with excellent results in 22 patients, good in 3, fair in 0 and poor in 0 ( P>0.05). In study group, wound infection or malunion was not seen, and only two patients showed postoperative wire tail irritability and recovered after the removal of wires. While in control group, wound infection was seen in 3 patients and malunion was observed in 2 patients, but all patients were with distal humerus lateral bone formations. The incidence of complications was 15% in control group, higher than 0% in study group ( P<0.05). Conclusion:Compared to open reduction internal fixation, ultrasound-guided closed reduction and internal fixation of Jakob type Ⅱ lateral humeral condyle fractures in children has similar therapeutic effect, but it can shorten operation time and reduce bleeding and complications.
