Objective To analyze the newly reported HIV-1 infection in several prefectures of Hubei Province，and analyze its influencing factors. Methods The limiting antigen avidity enzyme immunoassay(LAg-avidity EIA,LAg) was conducted on HIV-1 positive samples confirmed by Western blot of Hubei in 2017-2022. The demographic characteristics of the newly infected samples were analyzed by χ2 test.Logistic regression model was used to analyze influencing factors of new infection rate and predict the factors associated with the HIV-1 recent infection. Results There were 403 new cases of HIV-1 from 2017 to 2022 in several prefectures of Hubei Province, of which 77 were newly infected sorted by LAg,with a new infection rate of 19.11%. The newly confirmed HIV-1 persons of whom aged ≤24 years (40.00% new infection ratio), unmarried (29.41%), college or above (31.37%), and from Voluntary counseling and testing testing(VCT) clinics (40.00%) had a higher proportion of new infections, and the difference was statistically significant. Multivariate Logistic regression analysis showed that age ≤24 years old (aOR=4.346,95%CI: 1.342-14.075) and screening from the VCT clinic (aOR=6.761,95%CI: 1.460-31.319) were more likely to be newly infected. Conclusion The proportion of new HIV infection in several prefectures of Hubei province is relatively low in recent years.Further effective publicity and intervention measures for young students and the construction of VCT clinic should be continuously promoted to achieve early diagnosis and treatment.

Objective To compare the pathological diagnosis rate, number of punctures, and applicability to different lesion locations between a fork-tip biopsy needle and a conventional needle. Methods A retrospective collection of data was conducted on 137 patients who underwent endoscopic ultrasound (EUS)-guided fine needle biopsy (novel needle group, n=12) or aspiration (conventional needle group, n=125) at Zhongshan Hospital, Fudan University from January to August 2023. After propensity score matching at a ratio of 1∶5, there were 12 patients in the novel needle group and 60 patients in the conventional needle group. The pathological diagnosis rate and number of punctures were compared between the two groups. The stratified analyses on the size and location of lesions were performed. Results After matching, the pathological diagnosis rate was 91.7% (11/12) in the novel needle group, with a median of 2 punctures; the rate was 61.7% (37/60) in the conventional needle group, with a median of 3 punctures. No statistically significant differences in pathological diagnosis rate and number of punctures were observed between the two groups. Subgroup analysis showed that for lesions ≥20 mm, there was no significant difference in the number of punctures between the novel and conventional needles. The novel needle achieved a significantly higher pathological diagnosis rate for subepithelial tumors compared with the conventional needle (100.0% vs 30.4%, P＝0.019), whereas no significant differences were found for pancreatic masses or lymph node lesions. Conclusions Compared with EUS-guided aspiration using the conventional needle, EUS-guided biopsy using the novel fork-tip needle shows a trend toward a higher pathological diagnosis rate, with particular advantages in subepithelial tumors.

Objective To understand the clinical applicability and implementation of expert consensus on the implementation and removal of protective restraints in psychiatry,and to provide references for promoting the standardized practice of psychiatric protective restraints and updating the consensus.Methods By the convenience sampling method,a questionnaire survey was conducted among nurses from 480 hospitals in 30 provinces from June 15 to July 15,2024.The survey was conducted using the instrument for evaluating clinical applicability of guide-lines(version 2.0)and a self-compiled questionnaire on the clinical implementation of the restraint consensus.Results A total of 7,844 valid questionnaires were collected,with a valid questionnaire recovery rate of 93.78％.The results of clinical applicability scoring showed that the consensus had the lowest availability score(64.72％)and the highest acceptability score(76.74％).The results showed that nurses' receiving training and the level of their hospitals were the main influencing factors for scores in various dimensions(P＜0.05).4,774 participants(87.42％)believed that the application of consensus could enhance the standardization of nurses' restraint operations.The safety rate of the restraint consensus was 79.51％,and the economic ratio was 76.87％.Among the evaluators,1,739(22.17％)believed that there were implementation obstacles in the consensus.Conclusion The clinical applicability of the consensus is relatively good,and the application of the consensus helps to improve the standardization of clinical operations.In the future,efforts should be made to strengthen the promotion and training of the consensus,develop hierarchical promotion strategies according to the characteristics of medical institutions,and improve the quality of evidence for the consensus,so as to further enhance the clinical application effect of the consensus.

Objective:To review the diagnosis, treatment and quality of life of patients with primary immune thrombocytopenia (ITP) in seven medical centers in some areas of Hubei Province.Methods:A retrospective analysis was conducted on age, disease course, symptoms, diagnosis, and treatment status (including testing items, drug selection, and adverse reactions) of patients with ITP in seven medical centers in Hubei Province from January 2020 to December 2022. An online survey was conducted on the quality of life of patients using the ITP Patient Assessment Questionnaire (ITP-PAQ) .Results:Among the 1033 patients, those with newly diagnosed, persistent, and chronic ITP accounted for 39.8%, 19.1%, and 41.1%, respectively. Most patients exhibit varying degrees of bleeding. Regarding treatment, corticosteroids and thrombopoietin drugs are the most commonly chosen treatment drugs for ITP, and the adverse reactions to treatment mainly include diarrhea, liver dysfunction, and thrombosis. The ITP-PAQ survey of 125 patients revealed that ITP significantly impairs their life quality. Patients with ITP scored significantly lower in fatigue, sleep, fear, exercise, work, and social aspects.Conclusion:A relatively high proportion of patients with ITP progressed to the chronic phase. Corticosteroids and thrombopoietin drugs are the two main treatment drugs for ITP patients. The quality of life of patients with ITP is significantly reduced in multiple dimensions.

Objective:To compare the clinical characteristics and laboratory findings between elderly rheumatoid arthritis(ERA)with those of non-elderly rheumatoid arthritis(NERA)patients.Methods:A cross-sectional study was conducted.The study collected laboratory indicators of 1, 286 ERA and 3, 211 NERA patients admitted to the Affiliated Hospital of Zunyi Medical University between January 2015 and December 2022, including inflammatory indicators, complete blood count, liver/kidney function tests, blood lipid, and glycated hemoglobin(HbA 1c), etc. Results:Erythrocyte sedimentation rate, high-sensitivity C-reactive protein and rheumatoid factor in ERA patients were higher than those in NERA patients( t=13.940, 8.453, 3.400, all P<0.001). Hemoglobin, red blood cell count, red blood cell distribution width, albumin and total protein in ERA patients were lower than those in NERA patients( t=2.380, 6.546, 1.954, 12.800, 10.490, all P<0.05). The levels of aspartate aminotransferase, alkaline phosphatase, γ-glutamyl transferase, total bile acid, globulin, lactate dehydrogenase, creatinine and urea nitrogen in ERA patients were higher than those in NERA patients( t=3.366, 3.422, 2.760, 4.520, 3.676, Z=8.678, t=10.630, 17.640, all P<0.05). The levels of uric acid, alanine aminotransferase, total cholesterol, triglyceride, blood glucose and HbA 1c in female ERA patients were higher than those in NERA group( t=6.009, 1.100, 2.111, 3.954, 4.262, 2.667, all P<0.05). Decreased RBC, ALB, TP, GLB( OR=0.279, 95% CI: 0.133-0.582; OR=0.867, 95% CI: 0.809-0.930; OR=0.948, 95% CI: 0.903-0.996; OR=0.817, 95% CI: 0.798-0.833), and increased ALT, AST, Scr, BUN, LDL-C and TC( OR=1.013, 95% CI: 0.997-1.018; OR=1.046, 95% CI: 1.015-1.079; OR=1.026, 95% CI: 1.005-1.047; OR=1.034, 95% CI: 1.019-1.051; OR=1.373, 95% CI: 1.088-1.733; OR=1.266, 95% CI: 1.022-1.569)were independent influencing factors of ERA. Conclusions:ERA patients exhibit elevated inflammatory markers and are more prone to anemia, liver and kidney function damage, and malnutrition.Furthermore, female ERA patients are more likely to have abnormal uric acid, alanine aminotransferase, blood lipids, and blood glucose.

Objective:To explore the differences in clinical efficacy between Co-Cr-Mo guided multidirectional sliding growing rod technology (CMSG) and traditional growing rod in the treatment of neurofibromatosis type 1 dysplastic early-onset scoliosis.Methods:A retrospective analysis was conducted on the data of 20 patients with neurofibromatosis type 1 dysplastic early-onset scoliosis who underwent surgical treatment in the Scoliosis Department of Zhengzhou Orthopaedic Hospital Affiliated to Henan University from January 2010 to July 2022. There were 10 patients in the traditional rod group (treated with traditional growing rod surgery) and 10 patients in the CMSG group (treated with CMSG technology). All patients were ≤10 years old and had a Cobb angle ≥45°. The number of surgeries and the occurrence of complications were recorded. The Cobb angle of the main scoliotic curve, the Cobb angle of kyphosis from T 5 to T 12, and the height from T 1 to S 1 were measured from the imaging data to evaluate the correction of deformity and spinal growth. Results:There were no significant differences in age, gender, follow - up time, preoperative Cobb angle, and preoperative Cobb angle of kyphosis from T 5-T 12 between the CMSG group and the TGR group ( P>0.05). The number of surgeries 1.3±0.67 and the total medical cost 91, 100±34, 700 yuan in the CMSG group were lower than those in the TGR group (5.3±1.77 times and 155, 800±45, 900 yuan], and the differences were statistically significant ( t=6.687, P<0.001; t=3.558, P=0.002). The Cobb angles of the main curve before surgery, after the first surgery, and at the last follow - up in the CMSG group were 69.7°±17.8°, 19.8°±9.7°, and 24.4°±9.0° respectively, while those in the TGR group were 62.0°±11.1°, 32.1°±11.4°, and 33.3°±11.6° respectively. The differences in Cobb angles after the first surgery and at the last follow-up between the two groups were statistically significant ( t=2.633, P=0.017; t=2.313, P=0.033). The Cobb angles of kyphosis from T 5 to T 12 before surgery, after the first surgery, and at the last follow - up in the CMSG group were 40.0°±24.2°, 21.0°±6.0°, and 33.6°±9.3° respectively, while those in the TGR group were 31.3°±14.5°, 26.3°±10.5°, and 32.3°±17.2° respectively. There were no significant differences in the Cobb angles of kyphosis from T 5 to T 12 after the first surgery and at the last follow-up between the two groups ( t=1.383, P=0.184; t=0.243, P=0.811). The heights from T 1 to S 1 before surgery, after the first surgery, and at the last follow-up in the CMSG group were 30.5±3.4 cm, 33.7±3.3 cm, and 37.9±4.8 cm respectively, with an annual increase of 1.18±0.39 cm. The heights from T 1 to S 1 in the TGR group were 29.1±3.0 cm, 31.4±2.9 cm, and 36.3±3.5 cm respectively, with an annual increase of 1.25±0.23 cm. There was no significant difference in the annual growth height of T 1-S 1 between the two groups ( t=1.367, P=0.189). During the follow-up period, 3 patients in the CMSG group had 3 complications: 1 case of coronal plane trunk decompensation, 1 case of rod fracture, and 1 case of distal junctional kyphosis. In the TGR group, 7 patients had 8 complications: 2 cases of wound rupture, 3 cases of screw loosening, 1 case of distal addition phenomenon, 1 case of proximal addition phenomenon, and 1 case of rod fracture. Conclusion:The Co-Cr-Mo guided multidirectional sliding growing rod technique is safe and effective in treating type 1 neurofibromatosis with malnutrition type early-onset scoliosis. It can effectively control the progression of spinal deformities,preserve the growth ability of the spine, and have a low overall incidence of complications.

Objective To determine the median effective dose(ED50)of remimazolam for preoperative sedation in pediatric patients aged 1-6 years using the modified Dixon sequential method.Methods This is a prospective clinical study.Pediatric patients scheduled for elective short surgery(surgery time≤1 h)under general anesthesia from January to July 2023 were selected.Inclusion criteria were age 1-6 years,an ASA physical status Ⅰ-Ⅱ and the preoperative parent separation anxiety scale(PSAS)score≥3 points.Remimazolam was administered intravenously preoperatively,and its sedative effect was assessed.The modified Dixon sequential method was used to determine the ED50 of remimazolam,with the initial dose set at 0.10 mg/kg and the dose increment set at 0.02 mg/kg.Sedation was considered successful(positive,included in positive group)if the child with sedation score≥2 points,preoperative PSAS score<3 points,and the mask acceptance score of 4 points during anesthesia induction.If any criterion was not met,sedation was considered failure(negative,included in negative group),and the next patient's dosage was increased by 0.02 mg/kg based on the previous patient's dosage.The test was completed after 7 consecutive positive and negative turning points appeared alternately.Probabilistic unit regression analysis was used to determine the ED50,ED95 and the corresponding 95%confidence interval(CI)of remimazolam for preoperative sedation.Postoperative recovery time and adverse events such as airway spasm,respiratory depression,hypotension,nausea and vomiting during anesthesia were recorded.Results A total of 23 pediatric patients were included,with 13 in positive group and 10 in negative group.There were no statistically significant differences in mean arterial pressure,pulse oxygen saturation or heart rate before and after sedation(P>0.05).Compared with negative group,positive group showed a significant reduction in preoperative parent separation anxiety and an increase in mask acceptance during anesthesia(P<0.05).There was no significant difference in sedation score and anesthesia awakening time between two groups(P>0.05).The ED50 of remimazolam for preoperative sedation in pediatric patients aged 1-6 years was 0.051 mg/kg(95%CI 0.033-0.065 mg/kg),and the ED95 was 0.077 mg/kg(95%CI 0.064-0.161 mg/kg).No adverse events such as airway spasm,respiratory depression,hypotension,nausea and vomiting occurred during anesthesia in any of pediatric patients.Conclusion The ED50 of intravenous administration of remimazolam for preoperative sedation in pediatric patients aged 1-6 years is 0.051 mg/kg(95%CI 0.033-0.065 mg/kg).

Objective To evaluate the efficacy of the enzyme-linked immunosorbent assay(ELISA),polymerase chain reaction(PCR),and gold chromatographic strip assay(GICA)in diagnosing clonorchiasis through a meta-analysis of diagnostic tests.Methods Relevant databases,including CNKI,the Wan Fang Database,VIP,and PubMed,were searched according to inclusion and exclusion criteria.Literature quality was assessed using RevMan 5.4 and Stata 18,and funnel plots,forest plots,and SROC curves were generated.Results A total of 50 articles met the inclusion criteria.Deeks'funnel plot analysis indicated no significant publication bias among the three methods.The combined effect size analysis revealed that the sensitivity and specificity of ELISA for detecting clonorchiasis were 0.93(0.89-0.95)and 0.94(0.92-0.96),respectively,with an area under the SROC curve of 0.98.For PCR,the sensitivity and specificity were 0.93(0.84-0.97)and 0.92(0.80-0.97),respectively,yielding an area under the SROC curve of 0.97.The sensitivity and specificity of the GICA method for detecting clonorchiasis were 0.91(0.83-0.96)and 0.95(0.87-0.98),respectively,with an area under the SROC curve of 0.97.Conclusions In the diagnosis of clonorchiasis,ELISA,PCR and GICA have high diagnostic value,but their ranges differ from each other.

The epidemiological and spatiotemporal clustering characteristics of dengue fever in Fujian Province were ana-lyzed,to provide a scientific basis for dengue fever prevention and control.Descriptive epidemiology,spatial autocorrelation a-nalysis,and spatiotemporal scanning were used to analyze dengue fever cases in Fujian Province from 2011 to 2023.In this peri-od,a total of 3 586 cases of dengue fever were reported in Fujian Province,including 2 360 local cases,1 134 imported cases from abroad,and 92 imported cases from China.Cases were reported in ten prefectures and cities of the province,and 81 out of 88 counties reported cases.Imported cases were reported throughout the year in Fujian Province,but the occurrence of local ca-ses showed clear seasonality.Local cases and domestic imports were concentrated in August to October,whereas overseas im-ports occurred primarily from June to October.The imported cases were mainly from Southeast Asian countries,but a trend of spreading from Southeast Asian countries to South Asia,Africa,the Americas,and other regions,was observed.Spatio-tem-poral clustering of dengue fever was found in Fujian Province(Moran's I value 0.14-0.66,P＜0.05),and the high-high ag-gregation areas were distributed primarily in Fuzhou,Quanzhou,and Putian.Spatio-temporal scanning detected three aggrega-tion areas:one main and two secondary.The aggregation time was from the end of July to October,and the distribution was primarily in Fuzhou,Quanzhou,Putian,Zhangzhou,and Xiamen.The distribution of dengue fever in Fujian Province showed clear spatial and temporal clustering from the end of July to October,and the distribution was primarily in Fuzhou,Quanzhou,Putian,Zhangzhou,and Xiamen.For high concentration areas,national health campaigns,mosquito prevention and control,epidemic surveillance,medical personnel training,and other relevant measures could be carried out in advance before local cases appear every year.Reduce local transmission of dengue fever due to importation.

Objective To invegtigate the possible etiology,clinical characteristics,and treatment effects of post tympanoplasty full-frequency bone conduction hearing loss in the operated ear.Methods A retrospective analy-sis was conducted on the possible causes,clinical manifestations,and diagnosis and treatment of 6 cases of full-fre-quency bone conduction hearing loss in the operated ear after tympanoplasty.Results The use of diluted epineph-rine during surgery,controlled hypotension during the operation,ethylene oxide in gelatin sponges,and the exces-sive pro-inflammatory factors produced postoperatively may be associated with the occurrence of full-frequency bone conduction hearing loss in the operated ear after tympanoplasty.Among the six patients,the main initial symptom was dizziness without vertigo or nystagmus.Two cases were ineffectively treated,one case was effectively treated,and three cases were cured.Among the four cases that received timely medication,three were effectively treated.Conclusion Full-frequency bone conduction hearing loss in the operated ear after tympanoplasty is related to various factors,and the clinical manifestations of patients are atypical,often manifesting as dizziness.Timely diagnosis through pure tone audiometry and timely treatment according to the sudden deafness treatment plan often leads to fa-vorable outcomes.
