Objective To comprehensively analyze the clinical characteristics and risk factors of children with refractory mycoplasma pneumonia(RMPP),precisely identify the joint predictors in these children,and construct a prediction model.This aims to offer a scientific foundation for the early identification of RMPP and the formulation of accurate treatment and medication strategies.Methods A retrospective analysis was performed on the clinical data of 282 children diagnosed with mycoplasma pneumoniae pneumonia(MPP)who were admitted to the Pediatric Department of the Seventh Medical Center of the Chinese People's Liberation Army General Hospital between August 1,2023,and February 29,2024.Among these children,119 with RMPP were classified into the RMPP group,while the remaining 163 with general MPP(GMPP)were assigned to the GMPP group.The clinical data of both groups,encompassing age,gender,duration of fever,symptoms,laboratory test indices,chest imaging data,complications,etc.,were compared.A logistic probability model(LogP model)for joint application was constructed.The discriminatory ability of the model was evaluated using the area under the receiver operating characteristic(ROC)curve,and the calibration of the model was assessed by means of a calibration curve.Results In comparison with the GMPP group,children in the RMPP group exhibited a significantly longer duration of fever(P=0.002).Moreover,they had a higher incidence of complications,including myocardial damage and coagulation dysfunction(P<0.05).Regarding inflammatory markers,the levels of C-reactive protein(CRP),procalcitonin(PCT),and lactate dehydrogenase(LDH)were notably elevated in the RMPP group(P<0.05),whereas the level of albumin(Alb)was lower(P=0.001).In the RMPP group,the levels of interleukin-2(IL-2),interleukin-5(IL-5),interleukin-8(IL-8),interleukin-1β(IL-1β),and D-Dimer were increased,while the levels of interleukin-6(IL-6)and interleukin-17(IL-17)were decreased(P<0.05).Chest computed tomography(CT)scans revealed a higher proportion of lung consolidation,pleural effusion,and atelectasis in the RMPP group(P<0.05).Multivariate logistic regression analysis demonstrated that CRP,total bilirubin(T-BIL),LDH,IL-17,and prothrombin time(PT)were independent risk factors for RMPP(P<0.05).The receiver operating characteristic(ROC)predictive model established based on these factors had an area under the curve(AUC)of 0.787(95%confidence interval[CI]:0.693～0.880),with a cutoff value of 0.421,a sensitivity of 0.786,and a specificity of 0.660.The calibration curve indicated that the predicted probability matched well with the reference probability,and there was no statistical difference in the results of the Hosmer-Lemeshow test(P>0.05).Conclusions The clinical features of children with RMPP are predominantly characterized by prolonged fever,moderate lung lesions,other organ injuries,and high inflammatory markers.CRP,T-BIL,LDH,IL-17,and PT can act as independent risk factors for RMPP.

OBJECTIVE: To evaluate the efficacy and safety of Wuda Granule (WDG) on recovery of gastrointestinal function after laparoscopic bowel resection in the setting of enhanced recovery after surgery (ERAS)-based perioperative care. METHODS: A total of 108 patients aged 18 years or older undergoing laparoscopic bowel resection with a surgical duration of 2 to 4.5 h were randomly assigned (1:1) to receive either WDG or placebo (10 g/bag) twice a day from postoperative days 1-3, combining with ERAS-based perioperative care. The primary outcome was time to first defecation. Secondary outcomes were time to first flatus, time to first tolerance of liquid or semi-liquid food, gastrointestinal-related symptoms and length of stay. Subgroup analysis of the primary outcome according to sex, age, tumor site, surgical time, histories of underlying disease or history of abdominal surgery was undertaken. Adverse events were observed and recorded. RESULTS: A total of 107 patients [53 in the WDG group and 54 in the placebo group; 61.7 ± 12.1 years; 50 males (46.7%)] were included in the intention-to-treat analysis. The patients in the WDG group had a significantly shorter time to first defecation and flatus [between-group difference -11.01 h (95% CI -20.75 to -1.28 h), P=0.012 for defecation; -5.41 h (-11.10 to 0.27 h), P=0.040 for flatus] than the placebo group. Moreover, the extent of improvement in postoperative gastrointestinal-related symptoms in the WDG group was significantly better than that in the placebo group (P<0.05). Subgroup analyses revealed that the benefits of WDG were significantly superior in patients who were male, or under 60 years old, or surgical time less than 3 h, or having no history of basic disease or no history of abdominal surgery. There were no serious adverse events. CONCLUSION The addition of WDG to an ERAS postoperative care may be a viable strategy to enhance gastrointestinal function recovery after laparoscopic bowel resection surgery.

From the perspective of the physiological basis of liver and kidney sharing the common source in traditional Chinese medicine(TCM),and by integrating the theory of kidney dominating bone,liver dominating tendon,and meridian sinew of TCM as well as the bone resorption and collapse theory,and non-uniform settlement theory and lower-limb musculoskeletal bowstring structure theory of modern orthopedics,the pathogenesis of osteonecrosis of the femoral head(ONFH)under the system of non-uniform settlement during bone resorption and multidimensional composite bowstring working in coordination with the theory of liver-kidney and muscle-bone was explored.The key to the TCM pathogenesis of ONFH lies in the deficiency of the liver and kidney,and then the imbalance of kidney yin-yang leads to the disruption of the dynamic balance of bone formation and bone resorption mediated by osteoblasts-osteoclasts,which manifests as the elevated level of bone metabolism and the enhancement of focal bone resorption in the femoral head,and then leads to the necrosis and collapse of the femoral head.It is considered that the kidney dominates bone,liver dominates tendon,and the tendon and bone together constitute the muscle-bone-joint dynamic and static system of the hip joint.The appearance of collapse destroys the originally balanced muscle-bone-joint system.Moreover,the failure of liver blood in the nourishment of muscles and tendons further exacerbates the imbalance of the soft tissues around the hip joint,accelerates the collapse of the muscle-bone-joint dynamic and static system,speeds up the process of femoral head collapse,and ultimately results in irreversible outcomes.Based on the above pathogenesis,the systematic integrative treatment of ONFH should be based on the TCM holistic concept,focuses on the focal improvement of internal and external blood circulation of the femoral head by various approaches,so as to rebuild the coordination of joint function.Moreover,attention should be paid to the physical constitution of the patients,and therapy of tonifying the kidney and regulating the liver can be used to restore the balance between osteogenesis and osteoblastogenesis,and to reconstruct the muscle-bone-joint system,so as to effectively delay or even prevent the occurrence of ONFH.

BACKGROUND: Patients with atrial fibrillation (AF) and prior stroke history have a high risk of cardiovascular events despite anticoagulation therapy. It is unclear whether catheter ablation (CA) has further benefits in these patients. METHODS: AF patients with a previous history of stroke or systemic embolism (SE) from the prospective Chinese Atrial Fibrillation Registry study between August 2011 and December 2020 were included in the analysis. Patients were matched in a 1:1 ratio to CA or medical treatment (MT) based on propensity score. The primary outcome was a composite of all-cause death or ischemic stroke (IS)/SE. RESULTS: During a total of 4.1 ± 2.3 years of follow-up, the primary outcome occurred in 111 patients in the CA group (3.3 per 100 person-years) and in 229 patients in the MT group (5.7 per 100 person-years). The CA group had a lower risk of the primary outcome compared to the MT group [hazard ratio (HR) = 0.59, 95% CI: 0.47-0.74, P < 0.001]. There was a significant decreasing risk of all-cause mortality (HR = 0.43, 95% CI: 0.31-0.61, P < 0.001), IS/SE (HR = 0.73, 95% CI: 0.54-0.97, P = 0.033), cardiovascular mortality (HR = 0.32, 95% CI: 0.19-0.54, P < 0.001) and AF recurrence (HR = 0.33, 95% CI: 0.30-0.37, P < 0.001) in the CA group compared to that in the MT group. Sensitivity analysis generated consistent results when adjusting for time-dependent usage of anticoagulants. CONCLUSIONS In AF patients with a prior stroke history, CA was associated with a lower combined risk of all-cause death or IS/SE. Further clinical trials are warranted to confirm the benefits of CA in these patients.

Objective To investigate the current situation and risk factors of falls in the rural community elderly aged 65 years and above in Chongqing City, and to provide references for developing preventive measures. Methods The multistage cluster random sampling method was used to select several rural communities in Chongqing City from September to December, 2019, and then the elderly aged 65 years and above who lived in the communities for one year were chosen to serve as the surveyed subjects. A self designed questionnaire (sociodemographic factors, exercise status, illness and medication status and fall to related information) was used to collect the data regarding falls occurring in the last year. The chi-square test and multi factor multi-variant logistic regression analysis were utilized to analyze the data, the used software was SPSS 25.0. Results A total of 801 rural community elderly people in Chongqing City were surveyed．The average age was (71.64±5.85) years old. 7.12% of elderly need cane or walker. 6.87% of them self-reported their health was poor. 42.57% of elderly seldom have the habit of exercise. The prevalence of heart disease, diabetes, osteoporosis, arthritis, cataract, deafness self-reported was 8.99%、8.11%、17.48%、25.97%、13.73% and 6.24% respectively. Totally 104 elderly people experienced 128 falls in the past 12 months, and the incidence rates of falls and falling times were 12.84% and 15.98% respectively．The multi-variant logistic regression analysis showed that poor heath status self-reported（OR=4.04，95% , CI：1.71-9.52）, diabetes （OR=2.68，95% CI： 1.41-5.12）, osteoporosis （OR=1.91 , 95% CI：1.16-3.15）, arthritis （OR=2.60 , 95% CI：1.65-4.11） and non self-care（OR=2.44，95% CI：1.16-5.16） were the risk factors for falls in the rural community elderly. Conclusions The incidence rate of falls in the rural community elderly aged 65 years and above in Chongqing City was low．It is necessary to formulate comprehensive intervention measures for the risk factors of fall so as to reduce the incidence rate of falls in the elderly.

Objective: To investigate current use of oral anticoagulant (OAC) therapy and influencing factors among coronary artery disease (CAD) patients with nonvalvular atrial fibrillation (NVAF) in China. Methods: Results of this study derived from "China Atrial Fibrillation Registry Study", the study prospectively enrolled atrial fibrillation (AF) patients from 31 hospitals, and patients with valvular AF or treated with catheter ablation were excluded. Baseline data such as age, sex and type of atrial fibrillation were collected, and drug history, history of concomitant diseases, laboratory results and echocardiography results were recorded. CHA₂DS₂-VASc score and HAS-BLED score were calculated. The patients were followed up at the 3rd and 6th months after enrollment and every 6 months thereafter. Patients were divided according to whether they had coronary artery disease and whether they took OAC. Results: 11 067 NVAF patients fulfilling guideline criteria for OAC treatment were included in this study, including 1 837 patients with CAD. 95.4% of NVAF patients with CAD had CHA₂DS₂-VASc score≥2, and 59.7% of patients had HAS-BLED≥3, which was significantly higher than NVAF patients without CAD (P<0.001). Only 34.6% of NVAF patients with CAD were treated with OAC at enrollment. The proportion of HAS-BLED≥3 in the OAC group was significantly lower than in the no-OAC group (36.7% vs. 71.8%, P<0.001). After adjustment with multivariable logistic regression analysis, thromboembolism(OR=2.48,95%CI 1.50-4.10,P<0.001), left atrial diameter≥40 mm(OR=1.89,95%CI 1.23-2.91,P=0.004), stain use (OR=1.83,95%CI 1.01-3.03, P=0.020) and β blocker use (OR=1.74,95%CI 1.13-2.68,P=0.012)were influence factors of OAC treatment. However, the influence factors of no-OAC use were female(OR=0.54,95%CI 0.34-0.86,P=0.001), HAS-BLED≥3 (OR=0.33,95%CI 0.19-0.57,P<0.001), and antiplatelet drug(OR=0.04,95%CI 0.03-0.07,P<0.001). Conclusion: The rate of OAC treatment in NVAF patients with CAD is still low and needs to be further improved. The training and assessment of medical personnel should be strengthened to improve the utilization rate of OAC in these patients.
