This study was aimed at summarizing the epidemiological characteristics and spatial-temporal changes of hemorrhagic fever with renal syndrome(HFRS)in Hubei Province,China from 2005 to 2021,to provide scientific evi-dence for HFRS prevention and control.Data on individual HFRS cases and population information in Hubei Province from 2005 to 2021 were collected from the China Disease Pre-vention and Control Information System.The temporal,spa-tial,and demographic distribution characteristics of HFRS cases are described,and statistical methods such as medians,rates,and composition ratios were used for analysis.Joinpoint re-gression and Spearman's rank correlation were used to analyze the temporal trends in incidence rates or composition ratios.Global autocorrelation and hotspot analysis were conducted for spatial clustering analysis.Binary logistic regression was per-formed to analyze risk factors for HFRS mortality.A total of 5 790 HFRS cases were reported from 2005 to 2021,including 117 deaths.The average annual incidence rate was 0.57 per 100 000 population,and the case fatality rate was 2.02％.The overall incidence rate of HFRS in Hubei Province showed an increasing trend(AAPC=4.05％,95％CI:1.32％-6.78％),whereas the case fatality rate showed a decreasing trend over the years(r,=-0.72,P=0.002).HFRS exhibited a bimodal pattern,with peaks in the spring/summer months(May to July)and in the autumn/winter months(November to January of the following year).The incidence rate during the autumn/winter peak was slightly higher than that in the spring/summer peak.The incidence rate in males was higher than in females(RR=2.96,95％CI:2.79-3.14).The three age groups with the highest incidence rates were 60-64 years(747 cases,1.55 per 100 000),65-69 years(515 cases,1.39 per 100 000),and 55-59 years(762 cases,1.23 per 100 000).The incidence rate(2005:0.05 per 100 000;2021:0.08 per 100 000)and proportion(2005:2.69％;2021:1.94％)of HFRS cases in individuals 14 years or younger showed no significant trend over the years(AAPC=0.14％,95％CI:-0.03％-0.31％;AAPC=-3.64％,95％CI:-8.79％-1.50％).The incidence rate(2005:0.58 per 100 000;2021:1.59 per 100 000)and proportion(2005:14.80％;2021:44.31％)in the age group of 60 years or a-bove showed an increasing trend over the years(AAPC=10.52％,95％CI:4.38％-16.66％;AAPC=175.98％,95％CI:143.20％-208.75％).HFRS cases exhibited significant spatial clustering(P＜0.05).The hotspots of HFRS in Hubei Province shifted from the northern region(Xiangyang,Suizhou,Jingmen)in 2005-2007 to the southern region(Qianjiang,Xiantao,Tianmen,Jingzhou)in 2020-2021.Older age(OR=1.02,95％CI:1.01-1.04)and the period of 2005-2008 versus 2017-2021(OR=0.98,95％CI:0.97-0.99)were associated with relatively higher risk of HFRS mortality.In recent years,the HFRS epidemic in Hubei Province has continued to escalate,and areas such as Qianjiang City and other ares in the middle and lower reaches of the Yangtze River have experienced high incidence rates.The population 60 years of age or above is gradually becoming more susceptible to the disease.Targeted measures should be implemented to curb the rising trend of HFRS.

Neck dissection(ND)is one of the main treatment methods for oral and maxillofacial malignancies.Although ND type is in con-stant improvement,but intraoperative peal-pull-push injury of the accessory nerve,muscle,muscle membrane,fascia and ligament induced shoulder syndrome(SS)is still a common postoperative complication,combined with the influence of radiochemotherapy,not only can cause pain,stiffness,numbness,limited dysfunction of shoulder neck and arm,but also may have serious impact on patient's life quality and phys-ical and mental health.At present,there is still a lack of a systematic evaluation and rehabilitation management program for postoperative SS of oral and maxillofacial malignant tumors.Based on the previous clinical practice and the current available evidence,refer to the relevant lit-erature at home and abroad,the experts in the field of maxillofacial tumor surgery and rehabilitation were invited to discuss,modify and reach a consenusus on the etiology,assessment diagnosis,differential diagnosis,rehabilitation strategy and prevention of SS,in order to provide clinical reference.

Objective:To design an improved lamina hook system and compare its biomechanical properties with traditional lamina hook system in fixation of lumbar spondylolysis.Methods:The thin layer CT data of the lumbosacral vertebrae of 20 healthy young male servicemen who underwent physical examination in the outpatient department of the 940th Hospital of Joint Logistics Support Force of PLA from January 2021 to August 2022 were collected. The age of the subjects was 20-30 years [(25.0±3.0)years]. A 3-dimensional model of the L 5 vertebral body was constructed using the 3-dimensional modeling software. The new improved lamina hook was designed according to the measurements including the thickness of the middle area, the longest longitudinal diameter, the curvature radius of the lower edge, the angle between the upper and lower tail ends, the thickness of the lower edge, and the longest diameter of the lower edge of the bilateral L 5 vertebral plates. One serviceman was selected from the aforementioned group to construct a linear finite element model of segments L 4-S using the 3-dimensional virtual software (normal model, model A), based on which, the L 5 bilateral spondylolysis model (model B), improved lamina hook model (model C) and traditional lamina hook models (model D) were designed. By constraining both sides of the sacrum and applying a longitudinal load of 400 N on the L 4 vertebral body, the upper 1/3 gravity of the body was simulated, and with a bending moment of 10 N·m along the X, Y, and Z directions, motions of forward flexion, backward extension, lateral bending, rotation, etc were simulated. The range of motion of segment L 4/5 and L 5/S 1 of model A was evaluated and compared with the findings of the previous researches to verify its effectiveness. The overall range of motion of models A, B, C, and D, the range of motion of segment L 4/5 and L 5/S 1, the maximum overall displacement, the maximum displacement and stress of the isthmus, the stress distribution and maximum stress of internal fixation of models C and D, and the stress distribution and maximum stress of the vertebral body of models C and D were compared. Results:(1) During forward flexion, backward extension, lateral bending and rotation, the range of motion of model A was 5.01°, 4.03°, 3.91° and 1.42° in segment L 4/5, and was 4.62°, 2.51°, 2.40° and 1.23° in segment L 5/S 1. (2) The overall range of motion, range of motion of segment L 4/5 and L 5/S 1 and maximum overall displacement of models A, C, and D were similar in axial compression, forward flexion, backward extension, left bending, and left rotation, while those of model B were significantly increased. (3) There was no significant difference in the maximum displacement of the isthmus of models A, C, and D under different motion modes, while the maximum displacement of model B in the isthmus was significantly larger than that of models A, C, and D, especially during rotation, increased by 295%, 277%, and 276% respectively. The maximum stress of the isthmus of model C was 0.938 MPa, 1.698 MPa, 0.410 MPa, 2.775 MPa, and 1.554 MPa respectively. The maximum stress in the isthmus of model D was 0.590 MPa, 1.297 MPa, 0.520 MPa, 3.088 MPa, and 2.072 MPa respectively. The maximum stress of the isthmus of models C and D was similar during axial compression and forward flexion, while the stress of the isthmus of model C was smaller than that of model D during backward extension, lateral bending, and rotation, decreased by 21.1%, 10.2%, and 25.0% respectively compared with model D. (4) The maximum stress of internal fixation in models C and D during forward flexion, backward extension, left bending, and left rotation was 135.220 MPa, 130.180 MPa, 200.940 MPa and 306.340 MPa respectively, and was 131.840 MPa, 112.280 MPa, 349.980 MPa and 370.140 MPa respectively. The maximum stress of internal fixation in the two models of internal fixation during forward flexion and backward extension was similar, while it was decreased by 42.6% and 17.2% in model C during left bending and left rotation, compared with model D. (5) The maximum stress of the vertebral body during forward flexion, backward extension, left bending, and left rotation was 79.787 MPa, 36.857 MPa, 37.943 MPa and 96.965 MPa respectively in model C, but was 80.104 MPa, 64.236 MPa, 196.010 MPa and 193.020 MPa respectively in model D. The maximum stress of models C and D was all distributed in the contact area with the internal fixation, and especially during backward extension, left bending, and left rotation, when it was reduced by 42.6%, 80.6%, and 49.8% of model C respectively, compared with that of model D. Conclusions:The improved laminar hook is more consistent with the Chinese anatomized structure of the lamina. Compared with the traditional lamina hook system, the improved lamina hook system can effectively reduce the displacement in all directions and range of motion of lumbar spondylolysis, therefor can significantly reduce the stress of internal fixation and vertebral body and has better biomechanical performance.

Temporomandibular joint (TMJ) diseases are common clinical conditions. The number of patients with TMJ diseases is large, and the etiology, epidemiology, disease spectrum, and treatment of the disease remain controversial and unknown. To understand and master the current situation of the occurrence, development and prevention of TMJ diseases, as well as to identify the patterns in etiology, incidence, drug sensitivity, and prognosis is crucial for alleviating patients′suffering.This will facilitate in-depth medical research, effective disease prevention measures, and the formulation of corresponding health policies. Cohort construction and research has an irreplaceable role in precise disease prevention and significant improvement in diagnosis and treatment levels. Large-scale cohort studies are needed to explore the relationship between potential risk factors and outcomes of TMJ diseases, and to observe disease prognoses through long-term follw-ups. The consensus aims to establish a standard conceptual frame work for a cohort study on patients with TMJ disease while providing ideas for cohort data standards to this condition. TMJ disease cohort data consists of both common data standards applicable to all specific disease cohorts as well as disease-specific data standards. Common data were available for each specific disease cohort. By integrating different cohort research resources, standard problems or study variables can be unified. Long-term follow-up can be performed using consistent definitions and criteria across different projects for better core data collection. It is hoped that this consensus will be facilitate the development cohort studies of TMJ diseases.

Objective To observe the alteration of thoracic and lumbar physiological curvature in adolescent idiopathic scoliosis(AIS)and the difference of physiological curvature between different types of scoliosis.Methods A retrospective analysis was conducted on 305 adolescent patients taken full spine X-ray in our hospital from January 2017 to December 2021.The patients were divided into normal group and scoliosis group.The normal group was composed of 179 patients,79 males and 100 females,aged 10 to 18 years old with an average of(12.84±2.10)years old,with cobb agle less than 10 degrees.The scol-iosis group was composed of 126 patients,33 males and 93 females,aged 10 to 18 years old with an average of(13.92±2.20)years old.The gender,age,Risser sign,thoracic kyphosis(TK)and lumbar lordosis(LL)in 2 groups were compared,and the TK and LL were also compared between different genders,different degrees of scoliosis and different segments of scoliosis.Re-sults The female ratio(P=0.001)and age(P＜0.001)in scoliosis group were higher than them in normal group;the ratio of low-grade ossification was higher in normal group than in scoliosis group(P=0.038).TK was significantly smaller in scoliosis group than in normal group(P＜0.001),but there was no significant difference in LL between the 2 groups(P=0.147).There were no significant difference in TK and LL between male and female.The TK was significantly bigger in mild AIS patients than in moderate AIS patients(P＜0.05),but there was no significant difference in LL between mild and moderate patients(P＞0.05).The TK and LL in different segments scoliosis were not found significant difference.Conclusion The physiological curvature of thoracic and lumbar spine is independent of gender.The thoracic physiological curvature becomes smaller in AIS patients,but lumbar curvature remains unchanged.The thoracic physiological curvature in mild AIS patients is greater than that in moderate AIS patients,but the lumbar curvature is almost unchanged between mild and moderate scoliosis and is similar with that in normal adolescent.The alteration of thoracic and lumbar physiological curvature in AIS patients may be related to relative an-terior spinal overgrowth,and the specific detailed mechanism needs to be further studied.

Objective To investigate the independent risk factors of comprehensive complication index(CCI)≥26.2 after radical resection of colon cancer,and use these factors to establish and verify a dynamic web-based nomogram model.Methods The clinical data of colon cancer patients who underwent radical resection in the Affiliated Hospital of Jiangnan University from November 2020 to April 2022 were retrospectively collected,and divided into main cohort(November 2020 to October 2021,n=438)and validation cohort(November 2021 to April 2022,n=196).CCI scores of all patients were obtained based on CCI calculator(http://www.assessurgery.com).Univariate and multivariate logistic regression analysis were performed to identify the risk factors for CCI≥26.2,and a nomogram model was constructed.Receiver operator characteristic curve(ROC),C index and calibration curve were used to evaluate the differentiation and consistency of predictive nomogram model,and the decision curve analysis was conducted to assess the clinical benefits of the model.Internal validation of the model is performed in the validation cohort.Results A total of 438 patients were identified in present study,of which 63 cases(14.4%)had CCI≥26.2.Multivariate logistic regression analysis revealed that age≥60 years(OR=2.662,95%CI 1.341-5.285,P=0.005),low third lumbar spine skeletal muscle mass index(L3MI;OR=4.572,95%CI 2.435-8.583,P<0.001),NRS2002≥3(OR=4.281,95%CI 2.304-7.952,P<0.001),and preoperative bowel obstruction(OR=3.785,95%CI 1.971-7.268,P<0.001)were significant independent risk factors for postoperative CCI≥26.2.Based on these results,a static and web-based dynamic nomogram was established(https://jndxfsyywcwksyf.shinyapps.io/DynNomCCI/).The C-index and area under the curve(AUC)of the nomogram were 0.742 and 0.787,respectively.The calibration curve indicated a good consistency between the predicted probability and the actual probability.In the validation cohort,the nomogram also presented good discrimination(C-index=0.722,AUC=0.795)and predictive consistency.The decision curve analysis indicated the clinical benefit and application value of the nomogram prediction model.Conclusion This easy-to-use dynamic nomogram based on 4 independent risk factors can conveniently and reliably predict the probability of CCI≥26.2 after radical resection of colon cancer,which helps optimize the preoperative evaluation system,formulate precise individualized treatment strategies,and enhance recovery after surgery.

Objective To investigate the role and underlying mechanism of miR-15b-5p on hypoxia/reoxygenation(H/R)induced human renal tubular epithelial cell(HK-2)injury by targeting forkhead box O1(FOXO1).Methods HK-2 cells in the log growth phase were set up as follows:(1)control group(normal culture)and H/R group(H/R induced culture).The expressions of miR-15b-5p and FOXO1 mRNA were detected using qRT-PCR,and the protein expression of FOXO1 was detected using Western blotting.(2)Control group(normal culture),H/R group(H/R induced culture),H/R+mimic control group(cells transfected with mimic control then induced by H/R),H/R+miR-15b-5p mimic group(cells transfected with miR-15b-5p mimic then induced by H/R),H/R+miR-15b-5p mimic+OE-NC group(cells co-transfected with miR-15b-5p mimic and OE-NC plasmid,then induced by H/R),and H/R+miR-15b-5p mimic+OE-FOXO1 group(cells co-transfected with miR-15b-5p mimic and FOXO1 overexpression plasmid,then induced by H/R).The expression of miR-15b-5p was detected using qRT-PCR,and the protein expressions of FOXO1,cleaved caspase-3,Bax,and Bcl-2 were detected using Western blotting.CCK-8 assay was used to detect cell viability.Cell apoptosis was measured by the TUNEL method.(3)Control group(normal culture),H/R group(H/R induced culture),H/R+miR-15b-5p mimic group(cells transfected with miR-15b-5p mimic then induced by H/R),and H/R+miR-15b-5p mimic+OE-FOXO1 group(cells co-transfected with miR-15b-5p mimic and FOXO1 overexpression plasmid,then induced by H/R).The protein expressions of LC3,p62 and Beclin1 were detected using Western blotting.LC3 immunofluorescence was used to detect the cell autophagy.The target reaction between miR-15b-5p and FOXO1 was assessed using dual luciferase reporting assay.Results Under an inverted microscope,it was observed that the control group had a higher number of cells,most of which were in a typical cobblestone shape and grew in a cobblestone-like manner;most of the cells in the H/R group contracted and became round,with a significant decrease in the number of adherent cells.In H/R-induced HK-2 cells,miR-15b-5p was significantly down-regulated,while miRNA and protein expression of FOXO1 was up-regulated(P<0.05).Luciferase assay results showed that miR-15b-5p directly targeted the 3'-UTR of FOXO1.Overexpression of miR-15b-5p increased cell viability,reduced cell apoptosis,and decreased autophagy in H/R-induced HK-2 cells(P<0.05).Compared with H/R+miR-15b-5p mimic group,the viability of HK-2 cells was decreased,the apoptosis and autophagy level were increased in H/R+miR-15b-5p mimic+OE-FOXO1 group(P<0.05).Conclusion miR-15b-5p inhibited autophagy and alleviated H/R-induced HK-2 cell injury by targeting FOXO1.

As an important model animal, fruit fly is characterized by outstanding genetic characteristics, relatively perfect nervous system, rapid reproduction, and low cost. Thus, it has been applied in the research on neuropsychiatric disorders in recent years, showing great potential in life science. The incidence of neuropsychiatric disorders has been on the rise, and the disorders have high disability rate and low case fatality rate. The global drug demand for such diseases is second only to cardiovascular and cerebrovascular diseases. At the moment, the demand of the drugs for the diseases have been rising, and it is an urgent task to develop related drugs. However, the research and development of the drugs are time-intensive and have a high failure rate. A suitable animal model can help shorten the time for drug screening and development, thereby reducing the cost and failure rate. This study reviews the application of fruit flies in several common neuropsychiatric disorders, which is expected to provide new ideas for the research and application of the model animals in traditional Chinese medicine.

Male patients with prolactinomas usually present with typical hyperprolactinemia symptoms, including sexual dysfunction and infertility. However, clinical factors related to sexual dysfunction and surgical outcomes in these patients remain unclear. This study aimed to investigate the outcomes of male patients with prolactinomas after transsphenoidal surgery and the risk factors affecting sexual dysfunction. This study was conducted on 58 male patients who underwent transsphenoidal surgery for prolactinomas between May 2014 and December 2020 at the First Affiliated Hospital of Sun Yat-sen University, Guangzhou, China. We evaluated the sexual function of patients before and after surgery through International Index of Erectile Function-5 scores, libido, and frequency of morning erection. Of the 58 patients, 48 (82.8%) patients had sexual intercourse preoperatively. Among those 48 patients, 41 (85.4%) patients presented with erectile dysfunction. The preoperative International Index of Erectile Function-5 scores in patients with macroprolactinomas were significantly higher than those in patients with giant prolactinomas (17.63 ± 0.91 vs 13.28 ± 1.43; P = 0.01). Postoperatively, the incidence of erectile dysfunction was 47.9%, which was significantly lower than that preoperatively (85.4%; P = 0.01). Twenty-eight (68.3%) patients demonstrated an improvement in erectile dysfunction. Tumor size and invasiveness were significantly correlated with the improvement of erectile dysfunction. Preoperative testosterone <2.3 ng ml^-1 was an independent predictor of improvement in erectile dysfunction. In conclusion, our results indicated that tumor size and invasiveness were important factors affecting the improvement of sexual dysfunction in male patients with prolactinoma. The preoperative testosterone level was an independent predictor related to the improvement of erectile dysfunction.
