Objective: To investigate the late identification and its influencing factors of newly reported HIV/AIDS cases in Shangcheng District, Hangzhou City, so as to provide insights into the development of strategies for early detection and identification of HIV/AIDS cases. Methods: Basic information, identification routes and CD4+T lymphocyte counts among newly reported HIV/AIDS cases in Shangcheng District from 2013 to 2022 were collected through the Chinese Disease Prevention and Control Information System. The proportion of late identification of newly reported HIV/AIDS cases was analyzed, and factors affecting late identification was analyzed by a multivariable logistic regression model. Results: Totally 1 052 HIV/AIDS cases were newly reported in Shangcheng District from 2013 to 2022, including 1 011 males (96.10%), and had a mean age of (32.90±12.39) years. There were 333 cases with late identification, accounting for 31.65%. The proportions of late identification have no significant changing trend from 2013 to 2022 (P>0.05). Multivariable logistic regression analysis showed that HIV/AIDS cases aged 25 years and older (25 to 49 years, OR=1.894, 95%CI: 1.350-2.658; 50 years and older, OR=3.010, 95%CI: 1.838-4.928) had a higher risk of late identification, while HIV/AIDS cases with college degree and above (OR=0.655, 95%CI: 0.459-0.936) and identified by voluntary counseling and testing (OR=0.542, 95%CI: 0.380-0.772) had a lower risk of late identification. Conclusions The proportion of late identification of newly reported HIV/AIDS cases in Shangcheng District from 2013 to 2022 was 31.65%. Age, educational level and identification route were important factors affecting late identification of HIV/AIDS cases in Shangcheng District.

Hip fractures are among the most common fractures in the elderly, presenting to be a leading cause of disability and mortality. Surgical treatment is currently the main treatment method for hip fractures. The incidence of perioperative malnutrition is increased after hip fractures in the elderly due to the comorbidities, decreased basal metabolic rate, accelerated protein breakdown, weakened anabolism and surgical stress. However, malnutrition not only increases the incidence of postoperative complications, but also leads to increased mortality, indicating an important role of perioperative nursing management of nutrition for the elderly patients with hip fractures. At present, there still lacks scientific guidance and application standards on perioperative nursing management of nutrition for the elderly patients with hip fractures. Therefore, the Orthopedic Nursing Committee of Chinese Nursing Association and the Editorial Board of Chinese Journal of Trauma organized relevant experts to formulate the Expert consensus on perioperative nursing management of nutrition for elderly patients with hip fractures ( version 2023) according to evidence-based medical evidences and their clinical experiences. Fourteen recommendations were made from aspects of nutrition screening, nutrition assessment, nutrition diagnosis, nutrition intervention and nutrition monitoring to provide guidance for perioperative nursing management of nutrition in elderly patients with hip fractures.

Objective To investigate the expression of differential genes in testicular tissue of patients with obstructive and non-ob-structive azoospermia by bioinformatics,and provide new markers for the diagnosis of non-obstructive azoospermia(NOA).Methods The microarray data of azoospermia related genes(GSE45885 and GSE9210)were downloaded from the gene expression comprehensive database(GEO)and analyzed online by GEO2R,and the NOA related differentially expressed genes(DEGs)were obtained.The common DEGs were determined by using Wayne's intersection.GO annotation and KEGG enrichment analysis of DEGs were carried out by using R software.The DEGs-related protein interaction network(PPI)was constructed with STRING.Then,the most significant Hub gene of NOA was screened out by Cytoscape software and visualization was performed.The diagnostic value of Hub gene for NOA was estimated by the receiver operating characteristics(ROC)curve and verified in GSE145467 data set.Results A total of 83 DEGs were obtained,of which 78 were down-regulated and 5 were up-regulated.GO enrichment analysis showed that DEGs was involved in biological processes(BP),including the development and differentiation of sperm cells,development of germ cells,assembly of motor cilia,etc.Cell composition(CC)mainly included sperm flagella,motor cilia,acrosome vesicles,spermatogenic nuclei,etc.Molecular function(MF)mainly included structural components,protein binding,heat shock protein binding and so on,which endowed com-pressive strength for extracellular matrix.KEGG-related pathways were involved in longevity regulation pathways,cell cycle and apopto-sis,and meiosis of oocytes in multiple species.The five Hub genes closely related to NOA,including SPAG5,CCNB2,AURKC,NCAPH and PTTG1,were screened by PPI network.The ROC curve showed that all the five Hub genes were potential genetic markers of NOA.Conclusion SPAG5,CCNB2,AURKC,NCAPH and PTTG1 genes may play the key role in the development of NOA and may be used as the new biomarkers for NOA.

Objective:To examine the risk factors for neuropathic pain (NP) after a spinal cord injury (SCI).Methods:A total of 115 patients with a SCI were analyzed retrospectively. They were divided into an NP group of 53 and a non-NP group of 62 according to the occurrence of NP. Gender, age, length of stay, occupation, level of education, cause of injury, spinal fracture, degree of SCI, the injury′s plane and complications at admission (diabetes, hypertension, anemia, venous thrombosis, pressure sores, urinary tract infection or hypoproteinemia) were recorded. T-tests and chi-squared tests were used to compare those factors between the two groups, and multivariate logistic regressions were evaluated to identify the risk factors for NP.Results:Twenty-three of the 53 cases of NP (43%) had developed within 1 month of the SCI. Thirty-seven (75%) experienced pain below the plane of the SCI. The main features reported were squeezing (34%) and numbness (26%). The multivariate logistic regression showed that the occurrence of NP was most strongly related to gender (women being particularly at risk) and venous thrombosis at admission.Conclusions:Women are at particular risk of feeling NP after an SCI, and venous thrombosis is an independent risk factor. NP should be diagnosed and treated quickly to reduce the negative impact on patients′ life quality.

Objective: To understand the relationships of social exclusion, personality trait and emotion regulation with willingness to seek help after being bullied, and to provide reference for rationalized intervention of campus bullying among middle school students. Methods: A tatal of 2 040 middle school students from a middle school in Jiangxi Province were selected as the research objects, and surveyed by general situation questionnaire, Olweus Bullying Questionnaire, Willingness to Seek Help Scale, social exclusion scale, personality scale and Emotion Regulation Scale. Among them, a further survey of 381 bullies was conducted and SPSS 26.0 was used for statistical processing of data. Results: About 55.88% (133/238) and 58.74% (84/143) reported willingness to seek help after being bullied among middle and high school students, respectively( χ 2=0.30, P >0.05). There were no significant differences in gender and residency( P >0.05). In junior middle school students, compared with the non help willingness group( 3.83± 0.78，3.35±1.03，3.33±1.03，29.81±7.77), the rejected scores of the help willingness group were lower(3.57±0.75), scores of affinity and openness in personality traits were higher(3.69±0.88，3.72±0.79), the cognitive reappraisal scores were higher( 32.42 ±8.25). Among senior middle school students, the rejected and expression suppression scores of the help willingness group were lower(3.51±0.67，26.96±7.47), while extroversion personality traits were higher(3.61±0.95). Multivariate unconditional Log binomial regression analysis showed that high score of expression suppression was associated with less willingness to seek help( OR=0.94, P =0.02). Conclusion Social exclusion, personality trait and emotional regulation may have certain influences on willingness to seek help after being bullied among junior and senior middle school students, effects varies by grade level.

Objective: To prove the efficacy of peritoneal dialysis on shock wave-induced acute lung injury of rats, and analyze its mechanisms. Methods: Forty-five adult Sprague-Dawley rats were randomly divided into three groups: control group, sham operation (Sham) group and peritoneal dialysis (PD) group. Sham group and PD group did abdominal catheterization before blast injury. The 55 kg shock wave (bst-I) was used to induce lung blast injury. After one hour of blast injury, PD group was given 2.5% peritoneal dialysate 20 ml to stay abdomen, which was released 30 min posted, repeated 12 cycles. After 6 hours of peritoneal dialysis, all of the rats were sacrificed. Partial damaged tissues in lung were used to evaluate the pathomorphologic changes by HE staining, and the remnants were used to measure the lung water content. Lung function was detected by blood gas analyzer and small animal detector from the arterial blood gas. The levels of serum inflammatory factors, such as tumor necrosis factor-α (TNF-α), interleukin (IL)-1β, IL-6 and monocyte chemoattractant protein-1 (MCP-1) were tested by ELISA. Results: The relative integrity of alveolar structure, interstitial edema and inflammatory cell infiltration in PD group were significantly improved than those in control group. The lung water content of PD group was significantly lower than that of control group (P<0.05). The levels of TNF-α, IL-1β, IL-6 and MCP-1 in serum of PD group were significantly lower than those in control group (all P<0.05). The blood oxygen saturation, oxygen partial pressure, oxygenation index, vital capacity, functional residual volume and maximum mid-expiratory flow rate in PD group were significantly higher than those in control group (all P<0.05). Conclusions Through reducing pulmonary edema and inflammatory factors, peritoneal dialysis can improve lung function in shock wave -induced acute lung injury of rats.

OBJECTIVETo estimate the long-term outcomes and the prognostic factors of homoharringtonine, cytarabine, daunorubicin or idarubicin (HAD/HAI) as induction chemotherapy in de novo acute myeloid leukemia (AML).

METHODSThe CR rate, overall survival (OS) rate, relapse free survival (RFS) rate were retrospectively assayed in 143 de novo AML patients who received the HAD/HAI induction chemotherapy. The outcomes were compared among prognostic groups according to world health organization (WHO) classification, genetic prognosis and initial white blood cell (WBC) count. The role of consolidation chemotherapy consisting of middle-dosage Ara-C (MD-Ara-C) on long term survival was evaluated.

RESULTSOf 143 patients, 112 (78.3%) achieved CR after the first course of HAD/HAI induction treatment, and early death occurred in only one case. Notably, the CR rate of patients with an initial WBC count ≥100×10(9)/L was not significantly different from those with an initial WBC count<100× 10(9)/L (70.4% vs 80.2%, P=0.266). The CR rate for the patients with favorable, intermediate and unfavorable integrated genetics risk factors was 93.7%, 71.4% and 61.3%, respectively, the difference between groups was statistically significant (P=0.001). Patients with FLT3-ITD mutation obtained similar CR rate (70.6%) to that of patients with FLT3 wild type (79.3%, P=0.528).The estimated 5-year OS rate and 5-year RFS rate for all patients was 40.0% and 37.0%, respectively, with a median follow-up of 24 (range 1-104) months. The median survival time was 30 [95%CI (12, 48)] months. 5-year OS and 5-year RFS of the 96 patients who achieved CR after first course chemotherapy without undergoing allo-HSCT in complete remission was 47.0% and 38.0%, respectively. 5-year OS was significantly higher in MD-Ara-C consolidation group than in no MD-Ara-C consolidation group among CR patients without allo-HSCT (58.0%, 19.0%, respectively, P=0.004). In patients who obtained CR after first course and received MD-Ara-C consolidation without allo-HSCT, the 5-year OS of patients with hyperleukocytosis was not significantly lower than that of patients without hyperleukocytosis (55.5%, 58.8%, respectively,P=0.419). FLT3-ITD mutation patients showed similar 5-year OS to that of wild type FLT3 patients (51.4%, 60.2%, respectively, P=0.482). And furthermore, 5-year OS of favorable, intermediate and unfavorable integrated genetics groups were 59.1%, 62.5%, 51.9%, respectively (P=0.332) in this subgroup.

CONCLUSIONHAD/HAI induction chemotherapy with sequential consolidation of MD-Ara-C could obtain satisfactory CR rate and long-term survival rate in de novo AML, especially for patients with hyperleukocytosis or FLT3-ITD mutation. It yet remains to be verified by large sample, prospective studies.

The present study evaluated the application of three dimensional echocardigraphy (3DE) in the diagnosis of atrial septal defect (ASD) and the measurement of its size by 3DE and compared the size with surgical findings. Two-dimensional and real-time three dimensional echocardiography (RT3DE) was performed in 26 patients with atrial septal defect, and the echocardiographic data were compared with the surgical findings. Significant correlation was found between defect diameter by RT3DE and that measured during surgery (r=0.77, P<0.001). The defect area changed significantly during cardiac cycle. Percentage change in defect size during cardiac cycle ranged from 6%-70%. Our study showed that the size and morphology of atrial septal defect obtained with RT3DE correlate well with surgical findings. Therefore, RT3DE is a feasible and accurate non-invasive imaging tool for assessment of atrial septal size and dynamic changes.
