Objective:To explore the external treatment methods of hemorrhoids based on ancient books and documents; To guide clinical medication.Methods:The relevant articles on external treatment of hemorrhoids using Chinese materia medica included in Zhong Hua Yi Dian (5th edition) were retrieved. Excel 2021 was used to analyze the properties, tastes, meridian tropism, external treatment methods and drug efficacy of Chinese materia medica included in the prescriptions, and the relevant discussion contents were sorted out according to the classification of external treatment methods of hemorrhoids. Results:A total of 255 articles in ancient books were included, involving 165 prescriptions. 146 kinds of Chinese materia medica for external treatment of hemorrhoids were selected. The medicinal properties were mainly cold and warm, the main tastes were pungent, bitter and sweet, and the meridian tropism mainly involved the liver, spleen, stomach, heart, lung and large intestine meridians. Fumigation, application and application are the most widely used external treatment methods. Chinese materia medica efficacy mainly includes heat clearing drugs, surface relieving drugs, resuscitation drugs, astringent drugs, anti venom, anti insect and anti itching drugs, and tonic drugs.Conclusions:Ancient physicians treated hemorrhoids with both cold and heat, and paid equal attention to clearing heat and reducing fire, warming and activating blood circulation. They paid attention to the combination of local medication of lesions and the overall treatment of multiple meridians and multiple viscera, so as to achieve the simultaneous treatment of specimens. The treatment methods were rich, including fumigation and washing method to improve local microcirculation, application method using natural adhesive, coating method focusing on precise administration and ligation method of minimally invasive, forming a unique external treatment system, which can be used for modern clinical reference.

Objective:To analyze the epidemiological characteristics of cases involving monkey injuries at medical institutions surrounding Qianlingshan Park in Guiyang City, and to provide a reference basis for preventive measures to reduce monkey injuries and standardized post-exposure treatment.Methods:A retrospective cross-sectional study was conducted, collecting 1 900 cases of monkey-induced injuries in Qianlingshan Park treated at the outpatient clinic of Guizhou Provincial Center for Disease Control and Prevention and the Department of Surgery at Qianling Hospital, Guiyang City, from 2021 to 2024. Statistical analysis was performed using Pearson′s chi-square test.Results:Total of 1 900 cases of monkey-related injuries in Qianlingshan Park were collected from 2021 to 2024. The exposure time distribution exhibited significant seasonality, with 48.58% of cases occurring during July and August, totaling 923 cases, indicating a peak in the summer. There were 774 male patients and 1 126 female patients, with a ratio of 1∶1.45.and significant differences were observed between different age groups and genders (χ2=195.00, P<0.001), with the highest number of cases occurring in the 0-9 and 20-29 age groups, accounting for 22.05%(419 cases) and 21.79%(414 cases), respectively. The upper limbs were the most common injury site, accounting for 50.84% of the total cases(966 cases in total), with significant differences between gender and injury location (χ2=22.00, P<0.001), Among females, the proportion of injuries to the upper and lower limbs (30.11% and 16.47%, respectively) was higher than that among males (20.74% and 8.63%, respectively). The majority of injuries were classified as Grade Ⅲ, making up 57.38% of cases(1 069 cases in total). Self-treatment after exposure was the most common approach(60.44%), with significant differences observed between wound severity and treatment method (χ2=6.90, P=0.032), Patients with Grade Ⅱ and Grade Ⅲ wounds were more likely to choose self-management (26.84% and 33.23%, respectively) than outpatient management (15.14% and 24.15%). Approximately 98.05% (1 863 cases) of monkey-injured patients had received rabies vaccinations. Conclusions:This study analyzes monkey-related injuries in Qianlingshan Park from 2021 to 2024, clarifying the temporal distribution of injuries, demographic characteristics, injury sites, and treatment methods. The findings provide references for optimizing human-monkey conflict management and the prevention and control of zoonotic diseases in urban ecological parks.

Objective:To investigate the association of white matter hyperintensities (WMHs) with long-term stroke recurrence in patients with recent subcortical small infarcts (RSSIs).Methods:Consecutive patients admitted to the Department of Neurology, Hefei Hospital Affiliated to Anhui Medical University between January 2019 and August 2022 and met the clinical and imaging manifestations of RSSIs were collected. The demographic characteristics, baseline clinical data, and MRI features were collected. Using stroke recurrence as the endpoint event, the recurrence time was recorded, and Cox regression model was used to analyze relevant factors affecting stroke recurrence in patients with RSSIs.Results:A total of 202 patients were enrolled, including 138 males (68.3%), aged 67.9±10.5 years. Seventy-seven patients (38.1%) were mild WMHs, 64 (31.7%) were moderate WMHs, and 61 (30.2%) were severe WMHs. There were statistically significant differences in age, history of stroke, hypertension, hyperlipidemia, total cholesterol, infarct thickness, and infarct distribution among different WMHs severity groups (all P<0.05). The median follow-up time was 40.5 months (interquartile range, 27.7-49.0 months), and a total of 55 patients (27.2%) had stroke recurrence (ischemic stroke 54, occipital hemorrhage 1). Recurrence rates of stroke in the mild, moderate, and severe WMHs groups were 18.2%, 31.3%, and 34.4%, respectively. Cox regression analysis showed that WMHs were an independent risk factor for stroke recurrence (compared to the mild group, the risk ratio of the severe group was 2.225, 95% confidence interval was 1.116-4.436; P=0.023). Conclusion:The risk of long-term stroke recurrence in patients with RSSI is associated with the severity of WMHs.

Objective:To compare and explore the diagnostic performance of adding value of transabdominal and transvaginal contrast-enhanced ultrasound (CEUS) to Ovarian-Adnexal Reporting and Data System (O-RADS US) risk stratification and management system in differential diagnosis of adnexal masses.Methods:A total of 180 adnexal masses with solid components in 175 women were enrolled retrospectively between September 2021 and November 2022. All patients underwent routine Doppler ultrasound examinations and CEUS examinations. Among these masses, 107 masses underwent with transabdominal CEUS, 58 masses underwent with transvaginal CEUS, and 15 masses underwent both transvaginal and transabdominal CEUS. All patients were scheduled for surgery and pathological results served as the reference standard. Routine Doppler ultrasound and CEUS images and video were reviewed by a subspecialty radiologist using Vuebox software. The O-RADS US was downgraded or upgraded according to the CEUS characteristics of the masses. The diagnostic accuracy was assessed using ROC curve analysis. The area under the ROC curve (AUC) was calculated to compare the diagnostic performance of adding value of transabdominal and transvaginal CEUS to O-RADS US.Results:The diagnostic performance of adding transabdominal and transvaginal CEUS to O-RADS US were both significantly higher than of O-RADS US alone (transabdominal CEUS: AUC 0.83 vs 0.76, P=0.018; transvaginal CEUS: AUC 0.92 vs 0.81, P=0.013). Combination of transvaginal CEUS and O-RADS US was superior to that of combination of transabdominal and O-RADS US in the differential diagnosis of adnexal masses ( P=0.047). When the maximal diameter of adnexal masses ≤40 mm, transabdominal combined with O-RADS US presented the lowest diagnostic performance, with an AUC of 0.73. Conclusions:Combination of transvaginal CEUS and O-RADS US was superior to that of combination of transabdominal and O-RADS US in assessing adnexal masses with solid components. When the maximal diameter of adnexal masses ≤40 mm, transvaginal CEUS examination was recommended.

Objective:To investigate the changes of intestinal mucosal barrier function related indexes [diamine oxidase and secretory immunoglobulin A (sIgA)] in peripheral blood of patients with rheumatoid arthritis (RA) and their correlation with peripheral immune function.Methods:A total of 40 patients with RA who admitted to the Rheumatology and Immunology department of the Second Hospital of the Shanxi Medical University were enrolled. We collected their clinical and laboratory data, and selected 20 age and gender matched people as the control group. Enzyme-linked immunosorbnent assay (ELISA) was used to detect the level of DAO and sIgA in the peripheral blood, the lymphocytes and CD4 + T subsets were detected by flow cytometry. Then t-test, rank sum test and correlation analysis were conducted for statistical analysis. Results:① The level of DAO in patients with RA was higher than that of healthy controls [205(164, 251) ng/ml vs 364 (276, 483) ng/ml, Z=-4.48, P<0.001], while the level of sIgA was decreased [3.64 (2.76, 4.83)×10 5 ng/ml vs 6.83 (4.80, 9.44)×10 5, Z=-3.84, P<0.001]. ② The absolute number of B and CD4 + T cells were increased in RA, the difference were statistically significant, but the absolute number of T, natural killer cells (NK) and CD8 + T cells were not significantly different between the two groups. For CD4 + T subsets, the absolute number of T helper cells (Th)1 and Treg cells in RA group were significantly decreased than healthy controls, but there were no statistical significant difference in the number of Th2 and Th17 cells. ③ The level of DAO was positively correlated with absolute number of Th17 cells in patients with RA ( r=0.36 P=0.038), and positively correlated with age and white blood cell count ( r=0.40, P=0.021; r=0.40, P=0.020), but no significant correlation among other indicators were found. ④ The serum sIgA level of RA patients in antimutated citrullinated vimentin antibody (MCV), antiperinuclear factor (APF) and antikeratin antibody (AKA) positive group were higher than those in the negative group [3.99(2.99, 5.58)×10 5 ng/ml vs 2.73(2.29, 3.05)×10 5 ng/ml, Z=-2.55, P=0.011; 5.49 (3.26, 5.70)×10 5 ng/ml vs 3.12 (2.29, 4.04)×10 5 ng/ml, Z=-2.28, P=0.023; 4.07 (3.19, 5.65)×10 5 ng/ml vs 2.88 (2.24, 3.86)×10 5 ng/ml, Z=-2.42, P=0.016], while there was no significant difference in DAO level between groups. ⑤ The DAO level of RA patients with pulmonary interstitial fibrosis was significantly higher than that in the group without pulmonary interstitial fibrosis [421 (216, 528) ng/ml vs 191 (150, 223) ng/ml, Z=-2.81, P=0.005], while there were no significant differences in DAO and sIgA levels among other groups. Conclusion:In RA patients with inte-stinal mucosal barrier impairment, the DAO level is increased, while the sIgA is decreased, and in addition, elevated peripheral blood Th17 may be involved in the process of intestinal mucosal barrier impairment.

Background::It is controversial whether the apolipoprotein E epsilon 4 allele ( APOE ε4) is a risk gene for human immunodeficiency virus (HIV)-related neurocognitive impairment. This meta-analysis aimed to summarize evidence of the associations between APOE ε4 and cognitive impairment in people living with HIV (PLWH). Methods::Our study conducted a systematic literature search of PubMed, Web of Science, Embase, Google Scholar, and ProQuest for studies published before April 11, 2022 that evaluated associations between APOE ε4 and cognitive impairment in adult PLWH (aged ≥18 years). We calculated pooled odds ratios (ORs) of global cognitive impairment and 95% confidence intervals (CIs) and standardized mean differences (SMDs) for specific cognitive domains between APOE ε4 carriers and non-carriers. Subgroup meta-analyses were used to evaluate the result profiles across different categorical variables. Results::Twenty studies met the inclusion criteria, including 19 that evaluated global cognitive impairment. APOE ε4 was significantly associated with global cognitive impairment in PLWH (OR = 1.36, 95% CI = [1.05, 1.78], number of estimates [ k] = 19, P = 0.02, random effects). Subgroup meta-analysis based percentage of females showed evident intergroup differences in global cognitive performance between ε4 carriers and non-carriers ( P = 0.015). APOE ε4 carriers had lower cognitive test scores than non-carriers in all seven cognitive domains, including fluency (SMD = -0.51, 95% CI = [-0.76, -0.25], P < 0.001, k = 4, I2= 0%), learning (SMD = -0.52, 95% CI = [-0.75, -0.28], P < 0.001, k = 5, I2 = 0%), executive function (SMD = -0.41, 95% CI= [-0.59, -0.23], P < 0.001, k= 8, I2= 0%), memory (SMD=-0.41, 95% CI= [-0.61, -0.20], P < 0.001, k= 10, I2= 36%), attention/working memory (SMD=-0.34, 95% CI= [-0.54, -0.14], P= 0.001, k= 6, I2= 0%), speed of information processing (SMD = -0.34, 95% CI = [-0.53, -0.16], P < 0.001, k = 8, I2 = 0%), and motor function (SMD = -0.19, 95% CI = [-0.38, -0.01], P = 0.04, k = 7, I2 = 0%). Conclusions::Our meta-analysis provides significant evidence that APOE ε4 is a risk genotype for HIV-associated cognitive impairment, especially in cognitive domains of fluency, learning, executive function, and memory. Moreover, the impairment is sex specific. Meta analysis registration::PROSPERO, CRD 42021257775.

Objective: To examine the associations between suicide and self-injury behavior with psychological adaptability of college students, so as to provide the basic information for prevention of suicide and self-injury behavior. Methods: A sample of 825 college students completed a self-report questionnaire that measured sociodemographic characteristics, anxiety, depressive symptoms, resilience, self-compassion, and forgiveness. Results: Among 825 college students, the prevalence rates of suicidal ideation, suicidal plan, suicidal preparation, and suicidal action were 9.9%, 3.5%, 2.5%, 1.8% respectively. The rate of self-injury was 11.8%. Compared with the group with low scores of forgiveness dimension, high score of forgiveness was the protective factor of suicidal psychological behavior (OR=0.26) and self-injury (OR=0.31) (P<0.05). Compared with the score of Connor-Davidson Resilience Scale in each scale of mental resilience, low score was the risk factor of self-injury (OR=2.11), while high score was the protective factor of suicidal mental behaviors (OR=0.51) (P<0.05). Compared with the middle scores of the self-compassion scale and hearland forgiveness scale, the low scores were the risk factors for suicidal psychological behavior (OR=1.66, 2.28), while the high scores were the protective factors for suicidal psychological behavior (OR=0.33, 0.44) and self-injury (OR=0.35, 0.39) (P<0.05). Conclusion Psychological resilience, self-compassion and forgiveness are significantly correlated with suicide and self-injury, suggesting that colleges and universities should pay close attention to the mental health status of college students and help them reduce the incidence by improving their self-psychological adjustment ability.
