Objective To investigate the efficacies of proximal femoral nail anti-rotation(PFNA)internal fixation in traction bed supine position and non-traction bed lateral position in the treatment of elderly unstable femoral intertrochanteric fractures.Methods The clinical data of patients with unstable femoral intertrochanteric fractures treated with PFNA internal fixation in our hospital were retrospec-tively analyzed,41 patients received treatment in traction bed supine position were included in the supine position group,and 55 patients treated received treatment in non-traction bed lateral position were included in the lateral position group.The perioperative related indicators,surgical reduction,hip Harris score,and incidence of complications in the two groups were analyzed.Results The operation time and incision length of patients in the lateral position group were shorter than those in the supine position group,and the intraoperative blood loss and fluoroscopy times were less than those in the supine position group,with statistically significant differences(P<0.05).There was no significant difference in the anesthesia mode,blood transfusion or hospital stay of patients between the two groups(P>0.05).There was no significant difference in the incidence of postoperative complications of patients between the two groups(P>0.05).There was no significant difference in neck-shaft angle,tip-apex distance or hip Harris score of patients between the two groups(P>0.05).Conclusion PFNA internal fixation in traction bed supine position and non-traction bed lateral position have the same effect in the treatment of elderly unstable femoral intertrochanteric fractures,while the non-traction bed lateral position for treatment has more advantages in shortening operation time,decreasing intraoperative blood loss,and reducing radiation exposure.

Objective: To investigate the characteristics of HIV-1 molecular transmission network among HIV/AIDS patients in Zhoushan City, Zhejing Province. Methods: The newly reported HIV/AIDS cases in Zhoushan City from 2020 to 2022 were selected. Basic information was collected and whole blood samples were obtained at the initial follow-up. The pol gene sequences of HIV-1 were amplified by RT-PCR and nested-PCR. HIV-1 subtypes were identified by Neighbor-Joining phylogenetic trees. The HIV-1 molecular transmission network was built and analyzed using Cytoscape 3.6.1 software. Results: A total of 222 HIV/AIDS cases were reported in Zhoushan City from 2020 to 2022, 200 whole blood samples were collected, and 152 sequences were obtained successfully, including 122 males (80.26%), 75 cases aged 50 years and above (49.34%), 109 cases with a junior high school education or below (71.71%), and 63 cases with commercial heterosexual contact (41.45%). The main subtypes were CRF07_BC and CRF01_AE, accounting for 45.39% and 21.05%, respectively. When the threshold of genetic distance was set to 1%, 20 molecular clusters were formed in 69 cases, with a clustering rate of 45.39%. Using the molecular network constituted by reported HIV/AIDS cases in 2020 as the baseline network, there were 2 active molecular clusters with ≥5 new cases in 2022, each with 9 cases, characterized mainly by individuals aged 50 or above, with a junior high school education or below, and transmission through commercial heterosexual sex. Conclusions The predominant HIV-1 subtypes among HIV/AIDS cases in Zhoushan City are CRF07_BC and CRF01_AE. Transmission through commercial heterosexual contact among middle-aged and elderly people is a main mode of HIV transmission.

Objective:To investigate the causal correlation between depression and stress urinary incontinence(SUI)using Mendelian randomization(MR)analysis.Methods:We searched the FinnGen Consortium database for genome-wide association studies(GWAS)on depression and obtained 23 424 case samples and 192 220 control samples,with the GWAS data on SUI provided by the UK Biobank,including 4 340 case samples and 458 670 control samples.We investigated the correlation between depression and SUI based on the depression data collected from the Psychiatric Genomics Consortium(PGC).We employed inverse-variance weighting as the main method for the MR study,and performed sensitivity analysis to verify the accuracy and stability of the findings.Results:Analysis of the data from the UK Biobank and FinnGen Consortium showed that depression was significantly correlated with an increased risk of SUI(P=0.005),but not SUI with the risk of depression(P=0.927).And analysis of the PGC data verified the correlation of depression with the increased risk of SUI(P=0.043).Conclusion:Depression is associated with an increased risk of SUI,while SUI does not increase the risk of depression.

OBJECTIVE: To evaluate the effect of wrist-ankle acupuncture (WAA) in pain and functional recovery after total knee arthroplasty (TKA). METHODS: From June to September 2020, 94 participants were included from the Second Hospital of Tangshan and randomly assigned to the WAA group (47 cases) and the sham WAA group (47 cases) by a random number table, receiving real or sham WAA treatment, respectively. The primary outcome measure involved the visual analogue scale (VAS) scores at rest and in motion. The secondary outcomes involved the range of motion (ROM) of the knee joints, straight-leg raising time, postoperative weight-bearing time, sufentanil consumption within 48 h of patient-controlled analgesia (PCA) pump, length of hospital stay, and postoperative complications. RESULTS: The VAS scores on the 3rd, 5th, and 7th postoperative days at rest and in motion was significantly lower in the WAA group than that of the sham WAA group (P<0.01). The ROM on the 1st, 2nd, and 3rd PODs was significantly higher in the WAA group than that of the sham WAA group (P<0.01). In comparison to the sham WAA group, the sufentanil consumption within 48 h of PCA pump was significantly less in the WAA group (156.3 ± 12.2 µg vs. 128.8 ± 9.8 µg, P<0.01). There was no significant difference in active straight-leg raising time, postoperative weight-bearing time, length of hospital stay, and postoperative complications between the two groups (P>0.05). CONCLUSIONS WAA could alleviate post-TKA pain, improve knee joint function, and reduce the sufentanil consumption within 48 h of PCA pump. WAA is a safe and effective treatment in the perioperative analgesic management for TKA.

The Guidelines for prevention and treatment of colorectal adenoma with integrated Chinese and western medicine are put forward by Nanjing University of Chinese Medicine and approved by China Association of Chinese Medicine. According to the formulation processes and methods of relevant clinical practice guidelines, the experts in clinical medicine and methodology were organized to discuss the key problems to be addressed in the clinical prevention and treatment of colorectal adenoma(CRA) and provided answers following the evidence-based medicine method, so as to provide guidance for clinical decision-making. CRA is the major precancerous disease of colorectal cancer. Although the prevention and treatment with integrated Chinese and western medicine have been applied to the clinical practice of CRA, there is still a lack of high-quality guidelines. Four basic questions, 15 clinical questions, and 10 outcome indicators were determined by literature research and Delphi questionnaire. The relevant randomized controlled trial(RCT) was retrieved from CNKI, Wanfang, VIP, SinoMed, PubMed, EMbase, Cochrane Library, Web of Science, and 2 clinical trial registries, and finally several RCTs meeting the inclusion criteria were included. The data extracted from the RCT was imported into RevMan 5.3 for evidence synthesis, and the evidence was evaluated based on the Grading of Recommendations, Assessment, Development, and Evaluations(GRADE). The final recommendations were formed by the nominal group method based on the evidence summary table. The guidelines involve the diagnosis, screening, treatment with integrated Chinese and western medicine, prevention, and follow-up of colorectal adenoma, providing options for the clinical prevention and treatment of CRA.

Objective: This cross-sectional investigation aimed to determine the incidence, clinical characteristics, prognosis, and related risk factors of olfactory and gustatory dysfunctions related to infection with the SARS-CoV-2 Omicron strain in mainland China. Methods: Data of patients with SARS-CoV-2 from December 28, 2022, to February 21, 2023, were collected through online and offline questionnaires from 45 tertiary hospitals and one center for disease control and prevention in mainland China. The questionnaire included demographic information, previous health history, smoking and alcohol drinking, SARS-CoV-2 vaccination, olfactory and gustatory function before and after infection, other symptoms after infection, as well as the duration and improvement of olfactory and gustatory dysfunction. The self-reported olfactory and gustatory functions of patients were evaluated using the Olfactory VAS scale and Gustatory VAS scale. Results: A total of 35 566 valid questionnaires were obtained, revealing a high incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain (67.75%). Females(χ2=367.013, P<0.001) and young people(χ2=120.210, P<0.001) were more likely to develop these dysfunctions. Gender(OR=1.564, 95%CI: 1.487-1.645), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), oral health status (OR=0.881, 95%CI: 0.839-0.926), smoking history (OR=1.152, 95%CI=1.080-1.229), and drinking history (OR=0.854, 95%CI: 0.785-0.928) were correlated with the occurrence of olfactory and taste dysfunctions related to SARS-CoV-2(above P<0.001). 44.62% (4 391/9 840) of the patients who had not recovered their sense of smell and taste also suffered from nasal congestion, runny nose, and 32.62% (3 210/9 840) suffered from dry mouth and sore throat. The improvement of olfactory and taste functions was correlated with the persistence of accompanying symptoms(χ2=10.873, P=0.001). The average score of olfactory and taste VAS scale was 8.41 and 8.51 respectively before SARS-CoV-2 infection, but decreased to3.69 and 4.29 respectively after SARS-CoV-2 infection, and recovered to 5.83and 6.55 respectively at the time of the survey. The median duration of olfactory and gustatory dysfunctions was 15 days and 12 days, respectively, with 0.5% (121/24 096) of patients experiencing these dysfunctions for more than 28 days. The overall self-reported improvement rate of smell and taste dysfunctions was 59.16% (14 256/24 096). Gender(OR=0.893, 95%CI: 0.839-0.951), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), history of head and facial trauma(OR=1.180, 95%CI: 1.036-1.344, P=0.013), nose (OR=1.104, 95%CI: 1.042-1.171, P=0.001) and oral (OR=1.162, 95%CI: 1.096-1.233) health status, smoking history(OR=0.765, 95%CI: 0.709-0.825), and the persistence of accompanying symptoms (OR=0.359, 95%CI: 0.332-0.388) were correlated with the recovery of olfactory and taste dysfunctions related to SARS-CoV-2 (above P<0.001 except for the indicated values). Conclusion: The incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain is high in mainland China, with females and young people more likely to develop these dysfunctions. Active and effective intervention measures may be required for cases that persist for a long time. The recovery of olfactory and taste functions is influenced by several factors, including gender, SARS-CoV-2 vaccination status, history of head and facial trauma, nasal and oral health status, smoking history, and persistence of accompanying symptoms.

Objective: To analyze the clinical epidemiological characteristics including composition of pathogens , clinical characteristics, and disease prognosis acute bacterial meningitis (ABM) in Chinese children. Methods: A retrospective analysis was performed on the clinical and laboratory data of 1 610 children <15 years of age with ABM in 33 tertiary hospitals in China from January 2019 to December 2020. Patients were divided into different groups according to age,<28 days group, 28 days to <3 months group, 3 months to <1 year group, 1-<5 years of age group, 5-<15 years of age group; etiology confirmed group and clinically diagnosed group according to etiology diagnosis. Non-numeric variables were analyzed with the Chi-square test or Fisher's exact test, while non-normal distrituction numeric variables were compared with nonparametric test. Results: Among 1 610 children with ABM, 955 were male and 650 were female (5 cases were not provided with gender information), and the age of onset was 1.5 (0.5, 5.5) months. There were 588 cases age from <28 days, 462 cases age from 28 days to <3 months, 302 cases age from 3 months to <1 year of age group, 156 cases in the 1-<5 years of age and 101 cases in the 5-<15 years of age. The detection rates were 38.8% (95/245) and 31.5% (70/222) of Escherichia coli and 27.8% (68/245) and 35.1% (78/222) of Streptococcus agalactiae in infants younger than 28 days of age and 28 days to 3 months of age; the detection rates of Streptococcus pneumonia, Escherichia coli, and Streptococcus agalactiae were 34.3% (61/178), 14.0% (25/178) and 13.5% (24/178) in the 3 months of age to <1 year of age group; the dominant pathogens were Streptococcus pneumoniae and the detection rate were 67.9% (74/109) and 44.4% (16/36) in the 1-<5 years of age and 5-<15 years of age . There were 9.7% (19/195) strains of Escherichia coli producing ultra-broad-spectrum β-lactamases. The positive rates of cerebrospinal fluid (CSF) culture and blood culture were 32.2% (515/1 598) and 25.0% (400/1 598), while 38.2% (126/330)and 25.3% (21/83) in CSF metagenomics next generation sequencing and Streptococcus pneumoniae antigen detection. There were 4.3% (32/790) cases of which CSF white blood cell counts were normal in etiology confirmed group. Among 1 610 children with ABM, main intracranial imaging complications were subdural effusion and (or) empyema in 349 cases (21.7%), hydrocephalus in 233 cases (14.5%), brain abscess in 178 cases (11.1%), and other cerebrovascular diseases, including encephalomalacia, cerebral infarction, and encephalatrophy, in 174 cases (10.8%). Among the 166 cases (10.3%) with unfavorable outcome, 32 cases (2.0%) died among whom 24 cases died before 1 year of age, and 37 cases (2.3%) had recurrence among whom 25 cases had recurrence within 3 weeks. The incidences of subdural effusion and (or) empyema, brain abscess and ependymitis in the etiology confirmed group were significantly higher than those in the clinically diagnosed group (26.2% (207/790) vs. 17.3% (142/820), 13.0% (103/790) vs. 9.1% (75/820), 4.6% (36/790) vs. 2.7% (22/820), χ²=18.71, 6.20, 4.07, all P<0.05), but there was no significant difference in the unfavorable outcomes, mortility, and recurrence between these 2 groups (all P>0.05). Conclusions: The onset age of ABM in children is usually within 1 year of age, especially <3 months. The common pathogens in infants <3 months of age are Escherichia coli and Streptococcus agalactiae, and the dominant pathogen in infant ≥3 months is Streptococcus pneumoniae. Subdural effusion and (or) empyema and hydrocephalus are common complications. ABM should not be excluded even if CSF white blood cell counts is within normal range. Standardized bacteriological examination should be paid more attention to increase the pathogenic detection rate. Non-culture CSF detection methods may facilitate the pathogenic diagnosis.

The present study developed an ultra-fast liquid chromatography coupled with triple quadrupole-linear ion trap composite mass spectrometry(UHPLC-QTRAP-MS) to simultaneously determine the content of potential active components in Scutellariae Barbatae Herba and also to provide a reference approach for screening out the differential quality control components among different batches of Scutellariae Barbatae Herba. Chromatographic separations were conducted on a Thermo Acclaim~(TM) RSLC 120 C_(18) column(3.0 mm×100 mm, 2.2 μm) in a gradient program. The mobile phase consisted of 0.1% aqueous formic acid and acetonitrile, and the column temperature was maintained at 40 ℃. The flow rate was 0.4 mL·min~(-1) and the injection volume was 2 μL. The targeted compounds were monitored in the multiple reaction monitoring(MRM) mode. The acquired data were processed by hierarchical cluster analysis(HCA) and partial least square discriminant analysis(PLS-DA). Sixteen compounds all showed good linear relationship within the corresponding linear ranges and the R~2 values were all higher than 0.993 2. The RSDs of precision, repeatability, and stability were less than or equal to 3.7%. Mean recovery rates were in the range of 95.67% and 104.8% with RSDs≤3.2%. According to HCA and PLS-DA, all samples were clustered into four categories. Scutellarin, acteoside, scutellarein, and scutebarbatine X(VIP>1) were considered as differential chemical markers in the four categories. In conclusion, the developed method can be used for the simulta-neous determination of the multiple components and quality control of Scutellariae Barbatae Herba.

Objectives: To investigate the clinical value of adjuvant chemotherapy(ACT) in patients with intrahepatic cholangiocarcinoma(ICC) who underwent radical resection and to explore the optimal population that can benefit from ACT. Methods: A retrospective cohort study method was adopted. The clinical and pathological data of 685 patients with ICC who underwent curative intent resection in 10 Chinese hepatobiliary surgery centers from January 2010 to December 2018 were collected;There were 355 males and 330 females. The age(M(IQR)) was 58(14) years (range: 22 to 83 years). Propensity score matching(PSM) was applied to balance the differences between the adjuvant and non-adjuvant chemotherapy groups. Log-rank test was used to compare the prognosis of the two groups of patients. A Bayesian network recurrence-free survival(RFS) prediction model was constructed using the median RFS time (14 months) as the target variable, and the importance of the relevant prognostic factors was ranked according to the multistate Birnbaum importance calculation. A survival prognostic prediction table was established to analyze the population benefiting from adjuvant chemotherapy. Results: Among 685 patients,214 received ACT and 471 did not receive ACT. A total of 124 pairs of patients were included after PSM, and patients in the ACT group had better overall survival (OS) and RFS than those in the non-ACT group(OS: 32.2 months vs. 18.0 months,P=0.003;RFS:18.0 months vs. 10.0 months,P=0.001). The area under the curve of the Bayesian network RFS prediction model was 0.7124. The results of the prognostic factors in order of importance were microvascular invasion (0.158 2),perineural invasion (0.158 2),N stage (0.155 8),T stage (0.120 9), hepatic envelope invasion (0.090 3),adjuvant chemotherapy (0.072 1), tumor location (0.057 5), age (0.042 3), pathological differentiation (0.034 0), sex (0.029 3), alpha-fetoprotein (0.028 9) and preoperative jaundice (0.008 5). A survival prediction table based on the variables with importance greater than 0.1 (microvascular invasion,perineural invasion,N stage,T staging) and ACT showed that all patients benefited from ACT (increase in the probability of RFS≥14 months from 2.21% to 7.68%), with a more significant increase in the probability of RFS≥14 months after ACT in early-stage patients. Conclusion: ACT after radical resection in patients with ICC significantly prolongs the OS and RFS of patients, and the benefit of ACT is greater in early patients.
