AIM:To analyze the association between mobile phone addiction and high myopia among college students.METHODS:We conducted a cross-sectional questionnaire survey in December 2022 on all students of a university in Shaanxi Province, and the questionnaire included socio-demographic characteristics, mobile phone addiction, high myopia, and lifestyle. Binary Logistic regression model was used to analyze the association between mobile phone addiction and high myopia among college students.RESULTS:A total of 19 952 college students were included. The prevalence of high myopia was 7.31%. The rate of mobile phone addiction was 25.68%, and the mobile phone addiction score was 37.59±13.38. The incidence of high myopia among college students with mobile phone addiction was higher than non-mobile phone addiction(P<0.001). After adjusting for socio-demographic characteristics and lifestyle, the risk of high myopia among college students with mobile phone addiction was 1.274 times(95%CI:1.131-1.434)higher than non-mobile phone addiction. For each point increase of total mobile phone addiction score, withdrawal symptoms score, salience score, social comfort score, and mood changes score, the risk of high myopia among college students increased by 0.9%(95%CI:1.005-1.013), 2.0%(95%CI:1.010-1.030), 2.6%(95%CI:1.010-1.043), 4.8%(95%CI:1.030-1.066), and 3.3%(95%CI:1.014-1.052), respectively.CONCLUSION:Mobile phone addiction is significantly associated with the increased risk of high myopia among college students, and early intervention of mobile phone use may reduce the risk of high myopia among college students.

Post-orgasmic illness syndrome (POIS) is a rare condition characterized by the rapid onset of extreme fatigue, flu-like symptoms, difficulty concentrating, depression, nasal congestion, rhinorrhea, itchy eyes, and other physical and psychological discomforts following ejaculation. This report presents the outcomes of two patients with POIS who underwent a two-year course of autologous seminal plasma subcutaneous cluster immunotherapy. Treatment efficacy was assessed using methods such as the symptom Visual Analogue Scale (VAS), the Union Physio-Psycho-Social Assessment Questionnaire (UPPSAQ)-70, and the Short Form 36 Health Survey (SF-36). The results suggest that autologous seminal plasma subcutaneous cluster immunother-apy may be a safe and effective therapeutic approach for POIS.

OBJECTIVE: To investigate whether adding 1 transverse screw (TS) to the triangular parallel cannulated screw (TPCS) fixation has a mechanical stability advantage for Pauwels type Ⅲ femoral neck fractures by conducting finite element analysis on four internal fixation methods. METHODS: Based on CT data of a healthy adult male volunteer's femur, three Pauwels type Ⅲ femoral neck fracture models (Pauwels angle 70°, Pauwels angle 80°, and Pauwels angle 70° combined with bone defect) were constructed using Mimics 21.0 software and SolidWorks 2017 software. Four different internal fixation models were built at the same time, including TPCS, TPCS+TS, three cross screws (TCS), and TPCS+medial buttress plate (MBP). The mechanical stability of different models under the same load was compared by finite element analysis. RESULTS: The femoral model established in this study exhibited a maximum stress of 28.62 MPa, with relatively higher stress concentrated in the femoral neck. These findings were comparable to previous studies, indicating that the constructed femoral finite element model was correct. The maximum stress of internal fixation in finite element analysis showed that TCS was the lowest and TPCS+MBP was the highest in Pauwels angle 70° and 80° models, while TPCS+TS was the lowest and TCS was the highest in Pauwels angle 70° combined with bone defect model. The maximum displacement of internal fixation in each fracture model was located at the top of the femoral head, with TCS having the highest maximum displacement of the femur. The maximum stress of fracture surface in finite element analysis showed that TCS was the lowest and TPCS was the highest in the Pauwels angle 70° model, while TPCS+MBP was the lowest and TPCS/TCS were the highest in the Pauwels angle 80° model and the Pauwels angle 70° combined with bone defect model, respectively. The maximum displacement of fracture surfece analysis showed that TPCS+MBP was the lowest and TCS was the highest in Pauwels angle 70° and 80° models, while TPCS+TS was the lowest and TCS was the highest in Pauwels angle 70° combined with bone defect model. CONCLUSION For Pauwels type Ⅲ femoral neck fractures, the biomechanical stability of TPCS+TS was superior to that of TPCS alone and TCS, but it has not yet reached the level of TPCS+MBP.

The irrational use of Chinese patent medicines （CPM） is becoming more and more prominent， which makes the demand for clinical practice guidelines of CPM gradually increase. In order to make domestic scholars understand the latest developments and existing problems of the CPM guidelines， and promote its development， this paper introduced the concept of CPM guidelines， summarized the characteristics of the two development modes， namely “taking CPM as the key” and “taking disease/syndrome as the key”， and analyzed the current methodological status of developing and reporting CPM guidelines. Based on the existed problems， three suggestions have been put forward to optimize the quality of CPM guidelines， which were clarifying the target users and scope of CPM guidelines， establishing an open and transparent mechanism of the personnel involvement and process steps， and formulating implementable and operable recommendations for the use of CPM.

The identification of clinical questions for clinical practice guidelines of Chinese patent medicine （CPM） is important for subsequent evidence retrieval， evaluation of evidence quality， formation of recommendations. This paper described a methodological proposal for the identification of clinical questions for CPM guidelines to highlight the characteristics of Chinese patent medicine and reflect its effect in specific stage of the disease. Considering four aspects， namely， the drug of Chinese patent medicine （D）， the specific disease stage （S）， comparison （C）， and specific outcome （O）， DSCO framework has been proposed to formulate the clinical questions. Multi-source information through scientific research， policy or standard documents， and clinical data are suggested for collecting clinical questions， and clear selection criteria should be set to finalize the clinical questions to be addressed by the guideline. In addition， the above process needs to be transparently and publicly reported in order to ensure the clarity and completeness of the guidelines.

Objective To investigate the risk factors for unplanned readmission within 30 days after discharge in cirrhotic patients with esophagogastric variceal bleeding undergoing transjugular intrahepatic portosystemic shunt(TIPS),and to construct a nomogram predictive model.Methods A total of 241 cirrhotic patients who underwent TIPS due to esophagogastric variceal bleeding in Affiliated Drum Tower Hospital of Nanjing University Medical School from January 2020 to June 2023 were enrolled as subjects,and unplanned readmission within 30 days was analyzed.According to the presence or absence of unplanned readmission,they were divided into readmission group with 36 patients and non-readmission group with 198 patients,and related clinical data were collected from all patients.The independent-samples t test was used for comparison of normally distributed continuous data between two groups,and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups;the chi-square test was used for comparison of categorical data between two groups.A logistic regression analysis was used to identify independent risk factors for unplanned readmission.A nomogram prediction model was constructed,and the receiver operating characteristic(ROC)curve was plotted to assess its discriminatory ability for unplanned readmission;the calibration curve was plotted to evaluate the consistency of the nomogram model in predicting unplanned readmission;the ResourceSelection package of R language was used for the Hosmer-Lemeshow goodness-of-fit test to evaluate the degree of fitting of the mode;the decision curve analysis was used to investigate the practicality of the model.Results Age(odds ratio[OR]=2.664,95%confidence interval[CI]:1.139-6.233,P<0.05),CTP score(OR=1.655,95%CI:1.098-2.495,P<0.05),and blood ammonia(OR=1.032,95%CI:1.016-1.048,P<0.05)were independent risk factors for unplanned readmission within 30 days after discharge in the patients undergoing TIPS.The multivariate analysis showed that for the nomogram predictive model constructed in this study,repeated sampling for 1 000 times using the Bootstrap method was performed for internal validation,and the area under the ROC curve was 0.773,which was significantly higher than that of age(0.582),CTP score(0.675),and blood ammonia(0.641).The calibration curve showed good consistency between the probability of unplanned readmission predicted by the nomogram model and the actual probability,and the Hosmer-Lemeshow goodness-of-fit test showed good degree of fitting(c2=5.647 3,P=0.686 7).Conclusion Age,CTP score,and blood ammonia are independent risk factors for unplanned readmission within 30 days after TIPS,and the nomogram prediction model constructed based on these factors can help to predict the risk of unplanned readmission in TIPS patients and provide an accurate decision-making basis for early prevention.

Objective To evaluate the risk of bias and reporting quality in randomized controlled trials(RCTs)of the Chinese medicine injection for acute cerebral infarction in the last five years.Methods RCTs literature on Chinese medicine injection in the treatment of acute cerebral infarction was systematically searched in CNKI,Wanfang Data,VIP,China Biology Medicine Database(CBM),PubMed,Embase and Cochrane Library from April 20,2018 to April 20,2023.The risk of bias and reporting quality of included RCTs were evaluated using the Cochrane Risk of Bias Tool(ROB 1.0)and CONSORT-CHM Formulas 2017,respectively.Results A total of 4 301 articles were retrieved,and 408 RCTs were included according to inclusion and exclusion criteria.The ROB evaluation results showed that the the majority of studies were rated as having an unclear risk of bias due to the lack of reporting on allocation concealment,blind method,trial registration information,and funding sources.The evaluation results of CONSORT-CHM Formulas 2017 showed that the number of reported papers of 17 items was greater than or equal to 50%,and the number of reported papers of 25 items was less than 10%,and most of the RCTs did not show the characteristics of TCM syndrome differentiation and treatment.Conclusion The quality of Chinese medicine injection in the treatment of acute cerebral infarction RCTs is generally low.It is recommended that researchers refer to the methodology design of RCTs and international reporting standards,improve the trial design,standardize the trial report,and highlight the characteristics of TCM syndrome differentiation and treatment.

Objective:To analyze the epidemiological characteristics of rabies in China from 2007 to 2023, and to provide reference evidence for tailoring strategies to facilitate the elimination of rabies in the country.Methods:Case data from 2007 to 2023 were obtained from China′s National Notifiable Infectious Disease Reporting Information System, and the spatial, temporal, and demographic features of cases were analyzed.Results:From 2007 to 2023, a total of 18 751 human rabies cases were reported in China, with an average annual incidence rate of 0.08 per 100 000. The average annual percentage change (AAPC) in incidence rate was -18.58% (95% CI: -21.32% to -15.75%, P<0.05), with three significant turning points in 2011, 2018, and 2021. Based on the trend of the epidemic, Chinese provinces can be roughly divided into five categories. The geographical range affected by rabies has decreased from 23 provinces and 984 counties (districts) in 2007 to 17 provinces and 101 counties (districts) in 2023. Since 2019, the high-incidence counties (districts) have been mainly concentrated in the southwestern part of Hunan, the southern part of Henan, and the western part of Anhui. Fourteen provinces have reported no cases for at least two consecutive years. Males (70.24%) and farmers (72.18%) were the main affected groups, and the proportion of cases aged 65 and above increased from 17.43% in 2007 to 36.07% in 2023. Conclusions:The incidence of rabies in China has changed from endemic in many areas to sporadic, with the remaining endemic regions mainly located in parts of the middle and lower reaches of the Yangtze River. The main vulnerable groups are middle-aged and elderly farmers. The current prevention and control measures can effectively curb the transmission of rabies, but the decline of cases has slowed down recently.

Objective To investigate the epidemiological characteristics and mutation spectrum of monogenic diseases in Chinese population through a large-scale,multicenter carrier screening.Methods This study was conducted among a total of 33 104 participants(16 610 females)from 12 clinical centers across China.Carrier status for 223 genes was analyzed using high-throughput sequencing and different PCR methods.Results The overall combined carrier frequency was 55.58%for 197 autosomal genes and 1.84%for 26 X-linked genes in these participants.Among the 16 669 families,874 at-risk couples(5.24%)were identified.Specifically,584 couples(3.50%)were at risk for autosomal genes,306(1.84%)for X-linked genes,and 16 for both autosomal and X-linked genes.The most frequently detected autosomal at-risk genes included GJB2(autosomal recessive deafness type 1A,393 couples),HBA1/HBA2(α-thalassemia,36 couples),PAH(phenylketonuria,14 couples),and SMN1(spinal muscular atrophy,14 couples).The most frequently detected X-linked at-risk genes were G6PD(G6PD deficiency,236 couples),DMD(Duchenne muscular dystrophy,23 couples),and FMR1(fragile X syndrome,17 couples).After excluding GJB2 c.109G>A,the detection rate of at-risk couples was 3.91%(651/16 669),which was lowered to 1.72%(287/16 669)after further excluding G6PD.The theoretical incidence rate of severe monogenic birth defects was approximately 4.35‰(72.5/16 669).Screening for a battery of the top 22 most frequent genes in the at-risk couples could detect over 95%of at-risk couples,while screening for the top 54 genes further increased the detection rate to over 99%.Conclusion This study reveals the carrier frequencies of 223 monogenic genetic disorders in the Chinese population and provides evidence for carrier screening strategy development and panel design tailored to the Chinese population.In carrier testing,genetic counseling for specific genes or gene variants can be challenging,and the couples need to be informed of these difficulties before testing and provided with options for not screening these genes or gene variants.

Objective:To investigate the regulatory effects of acupuncture and moxibustion on chromatin remodeling complex core catalytic subunit of Brahma-related gene 1(Brg1),histone deacetylase(HDAC)3,HDAC9,and males absent on the first(MOF)in the colon tissue of rats with Crohn disease(CD). Methods:Using the random number table method,60 male Sprague-Dawley rats were divided into 5 groups,including a normal group,a model group,an acupuncture group,a medicinal cake-insulated moxibustion group,and an acupuncture-moxibustion group,with 12 rats in each group.CD rat models were prepared using 2,4,6-trinitrobenzene sulfonic acid(TNBS)in all groups except the normal group.The normal and model groups received no interventions.In the acupuncture group,rats were intervened with acupuncture at bilateral Zusanli(ST36)and Shangjuxu(ST37),20 min/session,once a day.The medicinal cake-insulated moxibustion group received medicinal cake-insulated moxibustion at Qihai(CV6)and bilateral Tianshu(ST25)with 2 cones per point per session,once a day.The acupuncture-moxibustion group received both acupuncture and moxibustion interventions simultaneously.Each intervention was performed for 10 consecutive days.Observations included general condition,disease activity,macroscopic damage,and pathological changes in the rat's colon tissue.Real-time fluorescence quantitative polymerase chain reaction was used to measure the mRNA expression of chromatin remodeling-related enzymes Brg1,HDAC3,and HDAC9,while Western blotting detected the protein expression of Brg1,HDAC3,HDAC9,and MOF in rat's colon tissue. Results:The model group showed significantly increased diarrhea score,occult blood score,macroscopic damage score of colon tissue,and colon macroscopic damage index(CMDI)score,as well as elevated mRNA expression levels of HDAC3 and HDAC9,protein expression levels of HDAC3,HDAC9,and MOF,and decreased mRNA and protein expression levels of Brg1 compared to the normal group(P<0.01).In contrast,compared to the model group,the diarrhea score,occult blood score,macroscopic damage score,CMDI score,mRNA expression levels of HDAC3 and HDAC9,and protein expression levels of HDAC3,HDAC9,and MOF were significantly reduced(P<0.05 or P<0.01),while the mRNA and protein expression levels of Brg1 were significantly increased(P<0.01)in the acupuncture group,the medicinal cake-insulated moxibustion group,and the acupuncture-moxibustion group. Conclusion:Both medicinal cake-insulated moxibustion and acupuncture,either used alone or in combination,can regulate the abnormal expression of chromatin remodeling-related enzymes Brg1,HDAC3,HDAC9,and MOF in the colon tissue,thus reducing colon inflammation in CD rats.
