OBJECTIVE: To investigate the effect of traditional Chinese Five-body balance exercise on patients with preserved ratio impaired spirometry (PRISm). METHODS: Fifteen patients with PRISm and 15 patients diagnosed with chronic obstructive pulmonary disease (COPD) were recruited from the Outpatient Department of Guang'anmen Hospital and Beijing Niujie Health Service Center from April to December, 2023. Participants in both groups attended supervised Five-body balance exercise training twice a week for 12 weeks. Patients with COPD continued their regular medication regimen during the intervention period. The endpoints were mean changes in the 6-min walk test (6MWT), St. George's Respiratory Questionnaire (SGRQ) score, cardiopulmonary exercise testing (CPET), pulmonary function, and scores of COPD assessment test (CAT), modified British Medical Research Council, Self-Rating Anxiety Scale, and Self-Rating Depression Scale from baseline to 12 weeks. Adverse events were monitored throughout the study. RESULTS: The PRISm group showed a significant improvement from baseline to week 12 in 6MWT, SGRQ symptom score, and forced vital capacity (FVC) compared to the COPD group (P<0.05). No significant between-group changes were observed in other outcome measurements (P>0.05). In addition, compared with baseline, both groups exhibited improvements in 6MWT, SGRQ score, and CPET at week 12 (P<0.05). The PRISm group also showed a significant increase in forced expiratory volume in 1 s and FVC, as well as a significant decrease in CAT score at week 12 (P<0.05). No adverse events were reported. CONCLUSION Patients with PRISm may benefit from Five-body balance exercise training, which can improve the exercise capacity, health-related quality of life, and lung function.

OBJECTIVE: Clinical characteristics and outcome in COVID-19 with brucellosis patients has not been well demonstrated, we tried to analyze clinical outcome in local and literature COVID-19 cases with brucellosis before and after recovery. METHODS: We retrospectively collected hospitalization data of comorbid patients and prospectively followed up after discharge in Heilongjiang Infectious Disease Hospital from January 15, 2020 to April 29, 2022. Demographics, epidemiological, clinical symptoms, radiological and laboratory data, treatment medicines and outcomes, and follow up were analyzed, and findings of a systematic review were demonstrated. RESULTS: A total of four COVID-19 with brucellosis patients were included. One patient had active brucellosis before covid and 3 patients had nonactive brucellosis before brucellosis. The median age was 54.5 years, and all were males (100.0%). Two cases (50.0%) were moderate, and one was mild and asymptomatic, respectively. Three cases (75.0%) had at least one comorbidity (brucellosis excluded). All 4 patients were found in COVID-19 nucleic acid screening. Case C and D had only headache and fever on admission, respectively. Four cases were treated with Traditional Chinese medicine, western medicines for three cases, no adverse reaction occurred during hospitalization. All patients were cured and discharged. Moreover, one case (25.0%) had still active brucellosis without re-positive COVID-19, and other three cases (75.0%) have no symptoms of discomfort except one case fell fatigue and anxious during the follow-up period after recovery. Conducting the literature review, two similar cases have been reported in two case reports, and were both recovered, whereas, no data of follow up after recovery. CONCLUSION These cases indicate that COVID-19 patients with brucellosis had favorable outcome before and after recovery. More clinical studies should be conducted to confirm our findings.

OBJECTIVE: To observe the effect of electroacupuncture (EA) at "Tianshu" (ST 25) and "Shangjuxu" (ST 37) on mental state, visceral sensitivity and protein expression of nerve growth factor (NGF), tyrosine kinase receptor A (TrkA) and transient receptor potential vanilloid 1 (TRPV1) of colonic tissue in diarrhea-predominant irritable bowel syndrome (IBS-D) rats, and to explore its possible mechanism on treating IBS-D. METHODS: A total of 36 male SD rats of SPF grade were randomized into a blank group, a model group, an EA group and a western medication group, 9 rats in each group. In the model group, the EA group and the western medication group, IBS-D model was established by enema of dinitrobenzene sulfonic acid (DNBS) combined with chronic restraint stress method. In the EA group, EA was applied at "Tianshu" (ST 25) and "Shangjuxu" (ST 37), with disperse-dense wave, in frequency of 2 Hz/100 Hz, 20 min each time, once a day for 7 days. In the western medication group, pinaverium bromide suspension was given by gavage (15 mg•kg^-1•d^-1) for 7 days. Before and after model establishment, and after intervention, the body mass, 24 h food intake and fecal water content were observed, the visceral sensitivity was detected by abdominal withdrawal reflex (AWR); after intervention, the mental state was evaluated by elevated plus maze (EPM) test, the protein expression of NGF, TrkA and TRPV1 was detected by immunohistochemistry and Western blot in the 4 groups. RESULTS: After model establishment, compared with the blank group, the body mass and 24 h food intake were decreased (P<0.05), first systolic latency of AWR was shortened and number of contraction wave of AWR was increased (P<0.05), and fecal water content was increased (P<0.05) in the model group, the EA group and the western medication group. After intervention, compared with the blank group, open arm residence time ratio (OT%) of EPM was decreased (P<0.05) and protein expression of NGF, TrkA, TRPV1 in colonic tissue was increased in the model group (P<0.05); compared with the model group, the body mass and 24 h food intake were increased (P<0.05), first systolic latency of AWR was lengthened and number of contraction wave of AWR was decreased (P<0.05), the fecal water content was decreased (P<0.05), OT% of EPM was increased (P<0.05), and protein expression of NGF, TrkA, TRPV1 in colonic tissue was decreased (P<0.05) in the EA group and the western medication group. CONCLUSION Electroacupuncture at "Tianshu" (ST 25) and "Shangjuxu" (ST 37) can relieve the anxiety and depression-like behaviors in IBS-D rats, down-regulate the protein expression of NGF, TrkA, TRPV1 in colonic tissue, so as to reduce the visceral sensitivity and relieve symptoms.

Objective To analyze the basic characteristics, drug features, prescription rules, and drug-symptom relationships of patients in the splenic deficiency and impairment stage, by data mining of medical records under the New Theory on Spleen Dampness Syndrome (Pi Dan Xin Lun, 《脾瘅新论》). Methods Medical records listed in the “New Theory on Spleen Dampness Syndrome – Understanding and Treatment of Metabolic Syndrome from the Perspective of Traditional Chinese Medicine”, and which were diagnosed with the spleen dampness syndrome at the splenic deficiency and impairment stage, during January 2004 and December 2016 were selected. These patients’ data, including basic information, clinical symptoms, laboratory examination results, traditional Chinese medicine (TCM) and western medicine diagnoses, treatment methods, prescriptions, etc., were collected. The collected data were subsequently compiled into a medical record database using the Epidata 3.1 data management software, followed by the use of Apriori algorithm provided in the SPSS Modeler 14.2 statistical software to investigate the association rules between drug-drug, drug-symptom, and drug-western medicine indices. Results (i) A total of 51 medical records were included, involving 17 types of syndromes. Among them, the top three with frequency ≥ 3 included “Phlegm and blood stasis, and thoracic obstruction” “Deficiency-weakness of the spleen Qi, and static blood blocking collaterals”, and “Deficiency-weakness of the spleen Qi, and static blood blocking collaterals”. Alternatively, of the 14 treatment methods, the top three treatments with frequency of ≥ 3 included “Activating Yang and eliminating turbidity, and removing phlegm and dredging channel blockage” “Strengthening the spleen and benefiting Qi, and eliminating phlegm to activate the channels”, and “Warming Yang and benefiting Qi, and expelling cold to remove obstructions”. Among the 15 prescriptions, the top three used with frequency ≥ 3 included Huangqi Guizhi Wuwu Tang (黄芪桂枝五物汤), Gualou Xiebai Banxia Tang (瓜蒌薤白半夏汤), and Ganjiang Huangqin Huanglian Renshen Tang (干姜黄芩黄连人参汤). Lastly, of the 83 drugs used for a total of 476 times, those with frequency ≥ 15 included Huanglian (Coptidis Rhizoma), Huangqi (Astragali Radix), Jiudahuang (Wine-processed Rhei Radix et Rhizoma), Jixueteng (Spatholobi Caulis), Shengjiang (Zingiberis Rhizoma Recens), Huangqin (Scutellariae Radix), and Guizhi (Cinnamomi Ramulus). (ii) For the drug-drug associations, under the criteria of support ≥ 15% and confidence = 100%, seven second-order association rules, seven third-order rules, and six fourth-order roles were identified. The top-ranking rule of each was “Huangqin (Scutellariae Radix) → Huanglian (Coptidis Rhizoma)” “Ganjiang (Zingiberis Rhizoma) + Huangqin (Scutellariae Radix) → Huanglian (Coptidis Rhizoma)”, and “Baishao (Paeoniae Radix Alba) + Guizhi (Cinnamomi Ramulus) + Jixueteng (Spatholobi Caulis) → Huangqin (Scutellariae Radix)”, respectively. Alternatively, the drug-symptom associations were analyzed under the criteria of support ≥ 5% and confidence = 100%, which derived eight second-order association rules, 31 third-order rules, and 30 fourth-order rules. The top-ranking association rule of each order was “Huangqi (Astragali Radix) → Limb edema” “Guizhi (Cinnamomi Ramulus) + Jixueteng (Spatholobi Caulis) → Limb numbness and pain”, and “Guizhi (Cinnamomi Ramulus) + Jixueteng (Spatholobi Caulis) + Huangqi (Astragali Radix) → Limb numbness and pain”, respectively. Similarly, the drug-western medicine index associations were investigated under the criteria of support ≥ 5% and confidence = 100%, and five second-order association rules, 16 third-order rules, and 16 fourth-order rules were identified. In this category, the top-ranking association rule of each order was “Qinpi (Fraxini Cortex) → Uric acid” “Huanglian (Coptidis Rhizoma) + Ganjiang (Zingiberis Rhizoma) → Glycated hemoglobin”, and “Huanglian (Coptidis Rhizoma) + Ganjiang (Zingiberis Rhizoma) + Huangqin (Scutellariae Radix) → Glycated hemoglobin”, respectively. Conclusion Through association rule mining, this study objectively and quantitatively demonstrated the drug-drug, drug-symptom, and drug-physicochemical index associations of patients with the spleen dampness syndrome at the splenic deficiency and impairment stage treated by Academician TONG Xiaolin. The results indicated that treatment for these patients adopted the “state-target” syndrome differentiation method. The drug combination was characterized by “small prescriptions”, targeting both the patient’s symptoms and signs (syndrome target) and western medicine indices (treatment target). This study could provide references for future research on the academic thoughts and medical experience of Academician TONG Xiaolin.

Objective: To evaluate the effectiveness of a comprehensive intervention for childhood obesity on self-efficacy, weight perception, and stage of behavior change, and to provide a scientific evidence for childhood obesity interventions. Methods: The study was a cluster randomized controlled trial. Twelve primary schools and 1 889 children (aged 7-11 years) from Dongcheng District in Beijing were recruited in September, 2013, and were administered a comprehensive intervention for childhood obesity. Six schools (930) were randomly allocated to the intervention group, and six schools (959) were randomly allocated to the control group. A face-to-face questionnaire survey was carried out, R 4.0.3 software was used to analyze the data, and multiple linear regression model was used to analyze the intervention effect. Results: After the intervention, mean (standard deviation) scores of self-efficacy among children in the intervention and control groups were (4.4±0.9) and (4.2±1.1), respectively. After the intervention, the proportion of children in the intervention group who underestimated or overestimated their body weight was 28.4% and 11.3 %, respectively, while the figures in the control were 37.1% and 6.9%; compared with the control, the risk of underestimating body weight decreased among children in the intervention group( OR=0.64, 95%CI=0.52-0.80, P <0.01), while the risk of weight overestimation increased( OR=1.79, 95%CI=1.26-2.54, P <0.01). After the intervention, the proportion of children in the contemplation or action stage of behaviour change was 65.3% and 83.6%, while the figures in the control group were 59.8% and 69.8 %, respectively; in comparison with the control group, more children in the intervention group were in comtemplation ( OR= 1.28 , 95%CI=1.03-1.59, P =0.02) or action stage of behaviour change( OR=2.59, 95%CI=2.04-3.27, P <0.01). Conclusion The comprehensive intervention for childhood obesity improved self-efficacy, weight perception, and facilitated behavior change, but may increase the risk of weight overestimation.

Objective:To compare the clinical outcomes of polyetheretherketone (PEEK) and titanium mesh as repair materials in the cranioplasty for cranial defect patients, and to screen the independent factors for postoperative complications of cranioplasty.Methods:A total of 95 patients with cranial defects admitted to our hospital from June 2012 to June 2019 were selected for this study. According to the different repair materials used in cranioplasty, these patients were divided into PEEK group ( n=36) and titanium mesh group ( n=59). General data (hospitalization cost, hospital stay, et al), postoperative complications (intracranial hemorrhage, subcutaneous effusion, infection, seizures, and implant exposure), postoperative plastic satisfaction, and improvement of postoperative neurological function (differences of Glasgow outcome scale [GOS] scores and Mini-mental State Examination [MMSE] scores before and 6 months after surgery) were compared between the 2 groups. Univariate and multivariate Logistic regression analyses were used to screen the independent factors for postoperative complications of cranioplasty. Results:The patients in the PEEK group had significantly higher hospitalization cost but significantly shortened length of hospital stay as compared with those in the titanium mesh group ( P<0.05). The overall incidence of complications in PEEK group was significantly lower than that in titanium mesh group ( P<0.05); the incidence of subcutaneous effusion in PEEK group was significantly lower than that in titanium mesh group ( P<0.05). The PEEK group had significantly higher proportion of patients with good satisfaction in postoperative plasticity, and significantly higher proportions of patients having increased GOS and MMSE scores as compared with the titanium mesh group ( P<0.05). Multivariate Logistic regression analysis showed that repair material was an independent factor for postoperative complications of cranioplasty ( OR=4.550, P=0.019, 95%CI: 1.281-16.161). Conclusion:As compared with titanium mesh, PEEK costs more, but its clinical application effect is better, especially in reducing postoperative complications; selection of appropriate repair materials can be used as one of the methods to reduce postoperative complications.

Objective Coronavirus disease 2019 (COVID-19) and tuberculosis (TB) are major public health and social issues worldwide. The long-term follow-up of COVID-19 with pulmonary TB (PTB) survivors after discharge is unclear. This study aimed to comprehensively describe clinical outcomes, including sequela and recurrence at 3, 12, and 24 months after discharge, among COVID-19 with PTB survivors. Methods From January 22, 2020 to May 6, 2022, with a follow-up by August 26, 2022, a prospective, multicenter follow-up study was conducted on COVID-19 with PTB survivors after discharge in 13hospitals from four provinces in China. Clinical outcomes, including sequela, recurrence of COVID-19, and PTB survivors, were collected via telephone and face-to-face interviews at 3, 12, and 24 months after discharge. Results Thirty-two COVID-19 with PTB survivors were included. The median age was 52 (45, 59) years, and 23 (71.9％) were men. Among them, nearly two-thirds (62.5％) of the survivors were moderate, three (9.4％) were severe, and more than half (59.4％) had at least one comorbidity (PTB excluded). The proportion of COVID-19 survivors with at least one sequela symptom decreased from 40.6％ at 3 months to 15.8％ at 24 months, with anxiety having a higher proportion over a follow-up. Cough and amnesia recovered at the 12-month follow-up, while anxiety, fatigue, and trouble sleeping remained after 24 months. Additionally, one (3.1％) case presented two recurrences of PTB and no re-positive COVID-19 during the follow-up period. Conclusion The proportion of long symptoms in COVID-19 with PTB survivors decreased over time, while nearly one in six still experience persistent symptoms with a higher proportion of anxiety. The recurrence of PTB and the psychological support of COVID-19 with PTB after discharge require more attention.

Objective To investigate the status of quality control of dental X-ray equipment in Beijing Dongcheng District, to explore the problems involved in radiation protection. Methods 41 medical dental X-ray machines were detected in Beijing Dongcheng District in accordance with Specification for testing of quality control in dental X-ray equipment (WS 581—2017). Results The qualified rate was higher in imported machines (100%) than that in domestic machines (76.92%), the overall qualified rate was 92.68%. In performance detection, the qualified rates were 100% except for the deviation of loading time (92.68%) and tube voltage (95.12%). No leakage was detected in 41 dental institutes. Conclusion The overall status of dental X-ray machines was good in Beijing Dongcheng District. More attention was paid to shield protection than to quality control of dental X-ray machines. Therefore, health administration should take measures to strengthen advocation of WS 581—2017, and improve radiation protection through routine equipment performance test, supervision of X-ray protection and radiation health education.

ObjectiveTo assess the screening ability of two new anthropometric indices： a body shape index （ABSI） and body roundness index （BRI） for metabolic associated fatty liver disease （MAFLD） in adults， and to determine the optimal cut-off value. MethodsBased on the valid baseline data collected from March 2018 to October 2019 in Dongguan City， Guangdong Province by South China Cohort （SCC） project， a total of 9 214 adults were included， with physical examination， ultrasound and laboratory tests. MAFLD was diagnosed according to the consensus statement of international experts. Body mass index （BMI）， waist circumference （WC） and waist-height-ratio （WHtR） were used as reference to evaluate the screening ability of ABSI and BRI. Spearman rank test and logistic regression model were used to compare the correlation between each index and MAFLD. The receiver operating characteristic curve （ROC） was used to compare the area under the curve （AUC）. ResultsThe prevalence of MAFLD was 31.41%， which increased linearly across the quartile of each index except ABSI. There was a positive correlation between each index and MAFLD but ABSI was the weakest （r_s=0.069 in males and r_s=0.045 in females） while BRI was stronger （r_s=0.409 in males and r_s=0.413 in females）. A multivariate logistic regression analysis of the presence of MAFLD for the highest quartile vs. the lowest quartile of each anthropometric measure， showed that ABSI had the lowest OR without statistical significance. The OR and 95%CI was 1.09 （0.85， 1.41） in males and 0.90 （0.74， 1.08） in females， respectively. BRI was similar to WHtR， and BMI had the strongest association whose OR and 95%CI was 61.15 （35.12， 106.47） in males and 20.07 （15.24， 26.43） in females， respectively. ABSI had the lowest AUC for MAFLD （0.55 in males and 0.53 in females） and the cut-off value was respectively 0.080 5 in males and 0.078 2 in females. BRI had a higher AUC （0.77 in males and 0.75 in females）， equal to WHtR and similar to WC （0.79 in males and 0.77 in females） but lower than BMI （0.81 in males and 0.79 in females）. The optimal cut-off value for BRI was 4.10 in males and 4.51 in females. BRI also showed a certain screening ability on MAFLD in lean/normal weight population （0.73 in males and 0.69 in females）， patients with diabetes （0.73 in males and 0.71 in females） and subjects with lean/normal weight and metabolic dysfunction （0.60 in males and 0.55 in females）. ConclusionsBRI can effectively identify MAFLD （AUC>0.7） and the optimal cut-off value is 4.10 for males and 4.51 for females， while ABSI performs poorly. Considering the screening on MAFLD in population with different characteristics， BRI shows a potential for use in early screening of MAFLD.
