Objective To investigate the acceptance and satisfaction of tuberculosis prevention and control personnel in Beijing with the patient management system, and to provide a basis for further improving the patient management model. Methods A survey was conducted on the current usage, satisfaction, willingness to use and system improvement opinions of the patient management system among medical staff involved in the supervision and medication management of pulmonary tuberculosis patients in Beijing. Results A total of 360 medical staff participated in the survey. ^“Patient management^” was the function with the largest number of users, accounting for 96.94%. The proportion of users of each module who believed that the module's design met actual work needs was over 90%. About 94.44% of respondents believed that patient management systems facilitated the transfer and sharing of information between institutions. And 90.83% of respondents thought that the patient management system was easy to operate, and 89.17% of respondents believed that patient management systems reduced workload. About 97.50% of respondents were satisfied with the overall use of the patient management system. The results of the influencing factor analysis showed that those with 3 or less modules designed to meet actual work were less satisfied than those with more than 3 modules, and the difference was statistically significant (P=0.001). Respondents put forward suggestions for improvement on the optimization of operational details such as system response speed, interface design, system login and query statistics. Conclusion Medical staff involved in the follow-up management of pulmonary tuberculosis patients are highly satisfied with their work using the patient management system. During the promotion and use, it is still necessary to continuously optimize the system functions according to work needs so that the system can truly facilitate work.

BACKGROUND:Research suggests that exercise interventions may be more advantageous than pharmacologic treatments or dietary restriction alone for fat loss,but fewer studies have simultaneously examined the effects of training modalities and training cycles on visceral and subcutaneous fat in obese populations. OBJECTIVE:To investigate the impact of training modalities and training cycles on visceral and subcutaneous fat in recessive obesity female college students. METHODS:Sixty-three female college students with hidden obesity(body mass index<24 kg/m2 and body fat content percentage≥30%)were recruited from Zhengzhou College of Commerce and Industry,and were randomly divided into a high-intensity intermittent training group(n=32)and a moderate-intensity continuous training group(n=31)using the lottery method.Subjects in both groups performed exercise training of corresponding intensity on a running platform and ensured that the exercise volume of both groups was equal,3 times per week,every 4 weeks as one training cycle for 16 weeks.Before training and at the end of each training cycle,subjects'visceral fat,subcutaneous fat,and overall fat were measured using the corresponding test devices. RESULTS AND CONCLUSION:The repeated measures F results indicated that the main effects of training cycles on visceral fat area,visceral fat index,abdominal subcutaneous fat thickness,percentage of body fat and body mass index were significant,while the main effects of training modalities were significant for subcutaneous fat thickness in the triceps brachii and scapula regions.All the interaction effects between training modalities and training cycles were significant(P<0.05).Results from the simple effect tests revealed that the significant simple effects of training modalities at the 4th and 12th weeks for visceral fat area and visceral fat index,at the 8th and 12th weeks for subcutaneous fat thickness in the triceps brachii,scapula region,and abdominal regions,and at the 8th week for the percentage of body fat and body mass index.Simple effects of training cycles were significant for all measures within each group.(3)The results of multiple comparison tests indicated that in the high-intensity intermittent training group,visceral fat area,visceral fat index,percentage of body fat,body mass index and abdominal subcutaneous fat thickness decreased sequentially at the 4th,8th,12th,and 16th weeks,and subcutaneous fat thickness of the triceps brachii and scapula decreased sequentially at the 8th,12th,and 16th weeks(P<0.05).In the moderate-intensity continuous training group,visceral fat area,visceral fat index,subcutaneous fat thickness of the triceps brachii and scapula,percentage of body fat and body mass index decreased successively at the 8th,12th,and 16th weeks,while abdominal subcutaneous fat thickness decreased successively at the 4th,8th,12th,and 16th weeks(P<0.05).To conclude,both training modalities and training cycles are factors influencing visceral and subcutaneous fat in recessive obesity female college students.Training modality primarily affects subcutaneous fat in the triceps brachii and scapular region,but the fat loss effects may converge over a longer training cycle;training cycle primarily affects visceral fat area,visceral fat index,abdominal subcutaneous fat,body fat content,and body mass index.

Objective: To analyze the association between alcohol consumption and lumbar disc herniation (LDH), so as to provide a reference for the development of prevention and treatment strategies for LDH. Methods: From May to July 2022, permanent residents aged ≥18 years from eight counties (cities/districts) in Gansu Province were selected using a multistage stratified random sampling method. Data on basic characteristics, alcohol consumption in the past 30 days, hypertension, and diabetes mellitus were collected through questionnaire surveys. LDH was determined based on imaging findings, combined with disease history or clinical symptoms. Multivariable logistic regression model was used to analyze the association between alcohol consumption and LDH, with subgroup analyses conducted by gender, age, ethnicity, and altitude of residence. Propensity score matching (PSM) was utilized for sensitivity analysis. Results: A total of 4 545 individuals were surveyed. There were 2 026 (44.58%) males and 2 519 (55.42%) females. The mean age was (44.82±15.33) years. The study participants were predominantly of Han ethnicity, with 2 598 persons accounting for 57.17%. The altitude of residence was mainly above 3 500 m, with 1 941 persons accounting for 42.71%. There were 574 alcohol drinkers, accounting for 12.63%. LDH was detected in 1 035 cases, with a detection rate of 22.77%. Multivariable logistic regression analysis showed that after adjusting for gender, age, physical activity, and hypertension, compared to non-drinking residents, alcohol-consuming residents exhibited a 27.6% reduction in the risk of LDH (OR=0.724, 95%CI: 0.544-0.963). No significant interaction effects on LDH risk were observed between alcohol consumption and gender, age, ethnicity, or altitude of residence (all Pfor interaction >0.05). The results of the sensitivity analysis indicated that compared to non-drinking residents, alcohol-consuming residents exhibited a 38.8% reduction in the risk of LDH (OR=0.612, 95%CI: 0.382-0.976). Conclusion Alcohol consumption was statistically associated with a lower risk of LDH.

Chinese materia medica has a wide range of clinical applications， but it has many active ingredients with different physicochemical properties， and the target organs， action pathways and mechanisms for different ingredients to exert their efficacy are not the same. Therefore， it is difficult to design and develop a co-delivery system loading multiple components of Chinese materia medica to maximize the synergistic therapeutic efficiency. Based on the characteristics of effectiveness and functionality of active ingredients， the strategies for multi-component co-delivery of Chinese materia medica can be categorized into two types：firstly， based on the effectiveness of active ingredients， new carriers such as liposomes， nanoparticles can be constructed to load multi-components of Chinese materia medica. secondly， based on the functionality of some active ingredients of Chinese materia medica， they are employed in the construction of co-delivery system， which can give play to the dual characteristics of their own efficacy and preparation functions. In this paper， we summarized the relevant research progress of the above two types of multi-component co-delivery strategies， and mainly discussed the pharmaceutical functions of the active ingredients in co-delivery systems， in order to find a more suitable multi-component co-delivery strategy， promoting the design and development of new delivery systems of Chinese materia medica.

BACKGROUND:In recent years,with the development of 3D printing,surgical surgery has become personalized and accurate.3D printed guide template technique can realize preoperative planning and intraoperative navigation,making surgery more accurate.In clinical orthopedic surgery for moderate and severe stiff scoliosis,there is still a problem that the accuracy of screw placement is not high,resulting in screw loosening and even nerve complications.There are few studies on 3D printed guide template technique to guide screw placement in surgery for severe stiff scoliosis. OBJECTIVE:To evaluate the clinical effect of the 3D printed guide template technique combined with multiple posterior derotation in the treatment of severe rigid scoliosis. METHODS:The clinical data of six patients with severe scoliosis undergoing 3D printed guide template technique of pedicle screw combined with multiple posterior derotation were retrospectively analyzed.There were 3 males and 3 females,with a mean age of(18.17±3.49)years(range,15-23 years).The changes of parameters related to lateral bending were analyzed at postoperative 2 weeks and 18 months,and the results were obtained by statistical analysis. RESULTS AND CONCLUSION:(1)The operation time was 280-540 minutes(mean 340.83±102.20 minutes).The intraoperative blood loss was 1 000-4 000 mL(mean 2 000.00±1 073.70 mL).The fixed segments were 9-14 vertebral bodies(mean 11.83±1.72),and no screw loosening occurred during the operation.(2)All patients were followed up.At postoperative 2 weeks,the anteroposterior and lateral radiography of the whole spine showed that the cobb angle,the distance between the vertical line of C7 on the coronal plane and the median line of S1,the distance between the vertical line of C7 in the sagittal plane and the posterior edge of S1,apical vertebral translation,thoracic kyphosis,and lumbar lordosis were significantly corrected.The average correction rate of the cobb angle in the main curve was 62.22%.After 18 months of follow-up,there was no significant change in all parameters compared with 2 weeks after operation;the orthopedic effect was satisfactory,and there was no infection or internal fixation fracture.(3)There was one case of delayed wound healing;scar healing appeared after dressing change treatment;no neurological complications occurred.(4)The results show that the 3D print-guide template combined with multiple posterior rod derotation technique is safe and effective in the treatment of severe rigid scoliosis,and the correction effect is satisfactory.

AIM: To systematically evaluate the efficacy and safety of low-concentrations atropine eye drops in controlling adolescent myopia.METHODS:A computer search was conducted on Wanfang Data, CNKI, VIP, PubMed, Cochrane Library, and Embase databases from January 2010 to March 2024 on clinical studies on low-concentration atropine eye drops for controlling adolescent myopia. Two researchers independently screened trials, extracted data, evaluated risk of bias and quality, and used Review Manager5.4 software to perform Meta-analysis.RESULTS:A total of 17 articles, involving 3 764 cases and 3 952 eyes, were included. The Meta-analysis showed that compared with the control group, low concentrations of atropine could effectively slow down the growth of axial length [MD=-0.15, 95% CI(-0.20, -0.10), P<0.00001], significantly controlled the changes in spherical equivalent [MD=0.39, 95% CI(0.29, 0.48), P<0.00001], and had a significant effect on pupil diameter [MD=0.80, 95% CI(0.33,1.28), P=0.0010] and amplitude of accommodation [MD=-2.54, 95%CI(-4.49, -0.60), P=0.01].CONCLUSION:Low-concentrations atropine are effective in controlling spherical equivalent and axial length of myopia in adolescents, significantly affecting pupil diameter and amplitude of accommodation, and effectively delaying the progression of myopia.

Ulcerative colitis is a chronic,non-specific inflammatory disease.The persistent damage to its intestinal epithelium is key to the development of the disease.In recent years,a new form of cell death has been identified by researchers-iron death-which is thought to be an important contributor to intestinal epithelial cell death.The occurrence of iron death is often associated with abnormal intracellular iron metabolism,reduced cystine/glutamate reverse transporter activity,abnormal lipid metabolism,voltage-dependent anion channel activation and overexpression of the Nrf2 gene.Iron death can lead to smaller mitochondria,increased membrane density and reduced number of cristae,unlike conventional cell death,which does not exhibit specific phenomena.Studies have found that TCM can alleviate iron death in intestinal epithelial cells by reducing intracellular iron content,inhibiting lipid reactive oxygen species production and regulating Nrf2 gene expression,thus acting as a treatment for ulcerative colitis.Therefore,Chinese medicine may become an important tool for the treatment of ulcerative colitis.This paper reviews the relationship between cellular iron death and ulcerative colitis and the research progress of Chinese medicine in treating ulcerative colitis through the iron death pathway.

Objective To compare the clinical efficacy and imaging results of uniportal interlaminar endoscopy(UIE)and unilateral biportal endoscopy(UBE)for the treatment of lumbar disc herniation.Methods The clinical information for 50 patients diagnosed with lumbar disc herniation was collected,and treated by UIE endoscopic surgery and UBE endoscopic surgery in the The First People's Hospital of Hefei city from March 2021 to October 2022 were retrospectively analyzed.The patients were divided into two groups,UIE group and the UBE group.Perioperative indexes including incision length,operation time,intraoperative blood loss,and surgical complications,clinical efficacy indexes including VAS scores of low back pain and leg pain before surgery,3 days after surgery,3 months after surgery,6 months after surgery,and 12 months after surgery,ODI scores of dysfunc-tion index,and imaging results including spinal canal area,vertebral space height,before surgery and 1 year after surgery were recorded and compared between the two groups.Results Both groups completed the procedure and were followed up for 12～18 months,with an average of 15 months.1 case was dural injury,no nerve root injury,and no nerve root symptoms during the follow-up.The symptoms of lumbar and leg pain were all relieved in both groups after the procedure.The UBE groups hawed larger surgical incisions,more intraoperative blood loss,and shorter operative time compared to the UIE group(P＜0.05,respectively).Both groups had significant develop-ments in the VAS scores,ODI scores of back,and leg pain at 3 days,3 months,6 months,and 12 months after the operation(all P＜0.05).The UIE group showed significant developments in the VAS scores and ODI scores of back and leg pain at 3 days and 3 months after the operation,as compared to the UBE group(P＜0.05).The imaging analysis did not showed significant changes in the height of intervertebral space and the angle of lumbar lordosis,but a significantly larger increase in the dural sac area in both groups one year after the procedure,and the UBE group had even a larger increase than the UIE group(P＜0.05).Conclusion Both UIE and UBE have good clinical efficacy and imaging results in the treatment of lumbar disc herniation via interlaminal approach.However,the UIE group is superior to the UBE group in terms of the operation time,intraoperative blood loss,postoperative VAS score of low back pain as well as the decompression effectiveness.

Objective:To investigate the application value of modified multivisceral trans-plantation (MMT) in chronic intestinal pseudo-obstruction (CIPO) secondary to autoimmune enteril leiomyositis (AEL).Methods:The retrospective and descriptive study was conducted. The clinico-pathological data of a recipient who was admitted to Beijing Tsinghua Changgung Hospital Affiliated to Tsinghua University on February 2022 and underwent MTT for CIPO secondary to AEL were collected. The recipient was a male, aged 29 years old. Results of preoperative histopathological examination showed that there were muscle plexus and ganglion cells in the rectum, sigmoid colon, ascending colon, intrinsic muscle layer of ileum, and a small amount of submucosal layer. There was also a small amount of chronic inflammatory cell infiltration in the muscle, indicating a high possi-bility of diagnosis of neurogenic CIPO.Results:(1) Surgical situations. The operation time was 14 hours and 30 minutes, and the cold ischemia time was 9 hours and 30 minutes. The intra-operative blood product dosage included 14 U of red blood cells, 1 400 mL of fresh frozen plasma, and two therapeutic doses of platelets. (2) Postoperative histopathological examination. Results of postoperative histopathological examination showed chronic inflammation and local erosion of the small intestine and duodenal mucosa, with scattered disappearance of the focal mucosal muscle layer; There is a large infiltration of CD3 + and CD8 + lymphocytes in the lamina propria, especially in the muscularis propria. In severe lesions, there is infiltration of ribbon lymphocytes in the subserosal and muscular layers; Muscle fiber degeneration, reduction, and fibrosis. Deposition of pigment granules in the cytoplasm of smooth muscle cells; No abnormalities were found in the intermuscular, submu-cosal ganglia, and Cajal cells; Fibrosis of the serosal layer with local cellulose exudation; Chronic inflammation of the colonic mucosa, scattered and focal lymphocyte infiltration in the local muscle layer, and myositis related changes. Pathological diagnosis was secondary CIPO induced by AEL. (3) Postoperative immune rejection, recurrence and treatment. Results of colonoscopy and histopatholo-gical examination at postoperative 8 days showed acute cellular rejection. The cell count of reci-pient′s B lymphocytes, CD3 + lymphocytes, CD4 + lymphocytes, and CD8 + lymphocytes were 27.00×10 3, 373.00×10 3, 179.00×10 3 and 142.00×10 3 cell/mL, respectively. Anti-immune rejection treatment was performed using tacrolimus, rabbit anti-human thymocyte immunoglobulin, methylprednisolone mycophenolate mofetil, and monoclonal antibodies against basil. The cell count of recipient′s B lymphocytes, CD3 + lymphocytes, CD4 + lymphocytes, and CD8 + lymphocytes at postoperative 57 days were 0.72×10 3, 239.59×10 3, 89.28×10 3 and 91.53×10 3 cell/mL, respectively. Results of colonoscopy and histopathological examination at postoperative 79 days showed the recurrence of AEL. The cell count of recipient′s B lymphocytes, CD3 + lymphocytes, CD4 + lymphocytes, and CD8 + lymphocytes were 0.32×10 3, 264.92×10 3, 46.95×10 3 and 169.54×10 3 cell/mL, respectively. The tacrolimus and methylprednisolone were used for treatment. Results of colonoscopy and histopathological examina-tion at postoperative 89 days showed AEL recurrence without remission. The cell count of recipient′s B lymphocytes, CD3 + lymphocytes, CD4 + lympho-cytes, and CD8 + lymphocytes were 0.28×10 3, 187.00×10 3, 55.52×10 3 and 92.45×10 3 cell/mL, respec-tively. The tacrolimus and methylprednisolone were used for treatment. Results of colonoscopy and histopathological examination at postoperative 92 days showed the intestinal mucosa had returned to a normal state. (4) Postoperative oral feeding time and time to get rid of parenteral nutrition. The recipient began oral feeding at postoperative 28 days and eliminated parenteral nutrition at postoperative 35 days. (5) Follow-up. The recipient was discharged 114 days after surgery and as of the follow-up deadline, the graft function was good. The recipient maintained a low-fat, high sugar, and high protein diet, completely consumed orally, with a body mass index of 22 kg/m 2, and has returned to normal work. Conclusion:MMT can be used for the treatment of CIPO secondary to AEL.
