Objective To study the association between statins use and liver-injury through prescription sequence symmetry analysis (PSSA) and evaluate the feasibility of the method to be used in Chinese Medical Insurance Database.Methods The data of the patients who prescribed both statins and liver-proactive drugs in Chinese Basic Medical Insurance Database in 2013 were selected as study subjects to calculate the adjusted sequence ratio (ASR) with signal detection methods to determine the study parameters and investigate the potential association between statins use and liver-injury.Results In 5 649 individuals which met the inclusion criteria,the washout period was set as one month and interval period was set as 60 days.The overall ASR of statins was 1.471(95％CI:1.395-1.550),the ASR of atorvastatin was 1.419 (95％CI:1.335-1.508),the ASR of simvastatin was 1.307 (95％CI:1.164-1.467).The positive signal was strong in 30 days interval period.Conclusions PSSA indicated that there might be potential association between statins use and liver-injury,especially the uses of atorvastatin and simvastatin.This signal detection method may be a fast and effective method in drug safety evaluation and can be used in Chinese Medical Insurance Database.

Objective: To explore the effectiveness of spinal guidance exercise on adolescents of mild idiopathic scoliosis, so as to provide an experimental reference and method for promoting adolescents spinal health. Methods: From the scoliosis screening, 96 children who met the diagnostic criteria were selected in June 2021, and were divided into the experimental group and the control group, with 48 cases in each group. The experimental group received a 12 week Longji Daoyin exercise training, and the control group received health education, observation and monitoring. Before and after the experiment, the axial trunk rotation (ATR) and scoliosis Cobb angle of the two groups were tested respectively, and the subjective sensation of the patients was measured by Scoliosis Research Society-22(SRS-22) questionnaire. Results: After 12 weeks, the ATR and Cobb angles of the experimental group decreased [( 5.02± 2.85，7.59±3.94)°]，compared to (7.08±2.84)° and (15.84±2.00)° before intervention( t =14.02, 17.09, P < 0.01 ). Scores of functional activity, self image and mental health in the SRS-22 score increased from (4.65±0.14)(3.49±0.21) and (3.99±0.17) to(4.77±0.14)(4.62±0.13)(4.42±0.13)( t =-4.86,-39.12,-13.92, P <0.01 ). The ATR and Cobb angles of the control group increased from (6.94±2.15)° and (15.82±1.76)° to (8.25±2.49)° and (18.63±3.12)°( t =7.44,8.99, P <0.01), and the scores of self image and mental health in the SRS-22 score decreased from (3.49±0.19) and (4.00±0.15) to (3.44±0.18) and (3.94±0.14)( t =-3.74,-4.39, P <0.05). Conclusion Early adolescent idiopathic scoliosis is easy to aggravate during the observation period. Longji Daoyin exercise is of preventive and therapeutic significance.

Objective:To investigate the effect of transcranial direct current stimulation (tDCS) on cognitive function of delayed encephalopathy after carbon monoxide poisoning (DEACMP) .Methods:A total of 58 patients with DEACMP admitted to the Emergency Medicine Department of Hudson International Peace Hospital from January 2018 to January 2020 were included. According to the random number table, the patients were randomly divided into study group and control group, with 29 patients in each group. Patients in both groups were given nutritional nerve therapy, improved microcirculation, adrenal cortical hormone and other drugs, as well as hyperbaric oxygen and rehabilitation training, once per day. The study group was treated with tDCS (electrode pads were placed and current stimulation was given 30 min/time) 1/d on the basis of conventional treatment, while the control group was treated with tDCS pseudo stimulation (electrode pads were placed and current stimulation was given for 10 s) 1/d for 30 days consecutively. The auditory event-related potential P300 (ERP-P300) was tested before and 30 days after treatment, and the Mini-Mental State Examination (MMSE) scale, Barthel index (BI) and the National Institutes of Health Neurological Impairment score (NIHSS) were used to evaluate and analyze the patients.Results:There was no significant difference in scores between the two groups before treatment (all P>0.05) . After 30 days of treatment, the MMSE score, orientation, memory, attention and computing power, and language ability of the study group were all higher than those of the control group, and the differences were statistically significant ( P<0.05) . 90 days after treatment, the BI of the study group was higher than that of the control group ( P<0.05) . After 30 days of treatment, the NIHSS score of the study group was significantly lower than that of the control group ( P<0.05) . The latency of ERP-P300 in the study group was shorter than that in the control group, and the amplitude was higher than that in the control group at 30 days after treatment, and the difference was statistically significant ( P<0.05) . The latency of ERP-P300 was negatively correlated with the total MMSE score before and after DEACMP treatment ( r=-0.837, -0.819, P<0.05) . The latency of ERP-P300 was negatively correlated with orientation, attention and computing power, and language ability before treatment ( r=-0.698, -0.675, -0.742, P<0.05) . Conclusion:TDCS treatment can help improve the cognitive function of DEACMP patients, and ERP-P300 test can help determine the cognitive function severity of patients.

Objective:To investigate the effect of clinical factors on the short-term prognosis of patients with acute carbon monoxide toxic heart disease.Methods:From October 2017 to December 2019, 92 patients with acute carbon monoxide poisoning (ACOP) and toxic heart disease admitted to the Department of Emergency of our hospital were enrolled in this study. The duration from poisoning to hospital admission, duration of coma, length of hospital stay, endotracheal intubation or not, admission to ICU ward or not, acute physiology and chronic health evaluation (APACHEⅡscore) at admission were recorded. The heart rate-corrected QT dispersion (QTcd) calculated based on electrocardiography results, as well as levels of serum trocalin I (cTnI) and creatine kinase isoenzyme (CK-MB) were recorded at admission, day 2, day 3, and hospital discharge. According to the diagnostic criteria of occupational cute toxic cardiopathy caused by chemicals, the patients were divided into three groups: 45 cases in the mild heart disease group (mild group), 35 cases in the moderate heart disease group (moderate group) and 12 cases in the severe heart disease group (severe group). The variables data of each group were presented as Mean±SD, and analyzed using one-way anova test. LSD- t test was used for pairwise comparison between the groups. Attributes data were compared using χ 2 comparisontest, and correlations were analyzed using Spearman correlation method and binary logistic regression analysis. Results:APACHE II score was significantly higher, and the durations of coma, and hospitalization time of severe heart disease group were significantly higher longer in the severe heart disease group than those ofin the mild and moderate groups, and the proportions of patients with early tracheal intubation to protect airway and admission in ICU ward were both significantly lower in the severe heart disease group than those ofin the mild and moderate moderate groups (all P < 0.05). The levels of CTnI and QTcd in each group increased immediately after admission, which was statistically different from that in the normal control group ( P < 0.05), while cTnI and QTcd at admission in the severe group were significantly higher than those in the mild and moderateother two groups ( P < 0.05). The levels of CK-MB in the severe group wereas significantly different from thoseat of the mild to and moderate groups at day 2 and day 3 after admission ( P < 0.05). The correlation between serum cTnI and APACHE II score at admission was R1 = 1.000 and R2 = 0.458. The correlation between QTcd and APACHE II score at admission was R1 = 1.000 and R2 = 0.765. Both of them were positively correlationsed with statistical difference ( P < 0.01). Conclusions:Patients with ACOP should admit to hospital as early as possible. For patients with severe hypoxia and no airway protection ability, an artificial airway should be established as soon as possible, and the patients should admit to the ICU at the early stage of poisoning to stabilize their condition. Changes of QTcd, serum cTnI, CK-MB and other related indicators should be monitored to detect cardiac injury in time and protect heart.

Objective To analyze the comorbidity and concomitant medications use in adult patients with chronic hepatitis C.Methods A descriptive epidemiological methods was carried out in adult patients with chronic hepatitis C and data from 2013 to 2015 were accessed through the China Medical Insurance database.Results Among a chronic HCV cohort of 2 958 cases,the top five comorbidities were diabetes,hypertension,ischemic heart disease,gastroduodenitis,and co-infection with HBV and HCV.The three most common concomitant medications prescribed for mentioned comorbidities were acarbose,metformin and repaglinide (Diabetes),nifedipine,amlodipine and metoprolol (Hypertension),aspirin,nifedipine and amlodipine (Ischemic heart disease),omeprazole,pantoprazole and levolfoxacin (Gastroduodenitis),ribavirin,pegylated interferon alpha-2a and alpha-2b (Co-infected with hepatitis B and C virus).Conclusion The five most frequent comorbidities in adult patients with chronic hepatitis C are diabetes,hypertension,isehemic heart disease,gastroduodenitis,and co-infection with HBV and HCV.A concomitant medication use in those patients with comorbidities causes potential drug-drug interactions.

Objective To observe the clinical effect of traditional Chinese medicine bone-setting technique using spinal,pelvi-lower extremity line to treat patients with knee osteoarthritis(KOA).Methods 426 patients with KOA were all from the First Affiliated Hospital of Hebei University of Traditional Chinese Medicine.They were randomly divided into experimental group(384 cases,57 cases of elimination,shedding and termination)by computer generated sequence.Traditional Chinese bone setting techniques were applied with spinal-pelvic-lower limb force line(divided into three parts:lumbar fixed point reduction method,hip joint push-pull and extension method and knee peripheral tendon recovery method every 3 days.2 weeks)treatment;The control group was the waiting treatment group(48 cases,6 cases were eliminated,abscission,termination),which was only used for clinical observation for 2 weeks.The main outcome index was WOMAC pain score.Secondary outcome measures were WOMAC stiffness score,functional score,standardized score and quality of life score(SF-12).The test time points were baseline,2 weeks after enrollment,and follow-up(14 weeks after enrollment).The control group was at baseline and 2 weeks after enrollment.Results Compared with baseline,WOMAC pain score,stiffness score,functional score and standardized score were all decreased in 2 groups 2 weeks after enrollment(P<0.05),but the experimental group was significantly decreased compared with the control group(P<0.001).SF-12 quality of life scores were all higher than before(P<0.001),but the experimental group was significantly higher than the control group(P<0.001).At follow-up,compared with 2 weeks after enrollment,WOMAC pain scores were increased(P<0.001),WOMAC stiffness,joint function and standardized scores were decreased(P<0.001),and SF-12 scores were increased(P<0.001).Conclusion The use of spinal-pelvi-lower extremity line of traditional Chinese medicine bone-setting technique in the treatment of KOA is effective in improving the knee joint function and improving the quality of life of patients,but the short-term effect of pain relief is good,and the long-term effect is not good.Its safety is good,and it can be considered in clinical application for KOA patients with joint dysfunction as the main manifestation.

ObjectiveThis study aimed to evaluate the clinical efficacy of Ruyi Zhenbaowan（RYZBW）in the treatment of initial and early knee osteoarthritis （KOA） through a prospective multicenter，randomized，double-blind，and placebo-parallel controlled trial. MethodFrom October 13^th， 2021 to December 25^th， 2021， 240 KOA subjects meeting the acceptance criteria were enrolled in 15 sub-centers including Wangjing Hospital， Chinese Academy of Chinese Medical Sciences， and they were randomly divided into observation group and control group， with 120 cases in each group. The intervention measures for the observation group were RYZBW + health education， and the intervention measures for the control group were RYZBW placebo + health education. The intervention period in both groups was four weeks， and they were followed up for four weeks after the intervention. The primary outcome measure was the total score of Western Ontario and McMaster University Osteoarthritis Index score （WOMAC score）， and the secondary outcome measures were the response rate of visual scale （VAS） pain score， WOMAC sub item scores （joint pain， joint stiffness， and joint function）， quality of life （SF-12） score， and traditional Chinese medicine （TCM） syndrome score. Result（1） Efficacy evaluation. The marginal model results showed that the observation group was better than the control group in improving the WOMAC total score and WOMAC pain score in the treatment of KOA with RYZBW， and the difference was statistically significant （P<0.05）. There was no significant difference between the two groups in improving VAS score response rate， WOMAC function score， WOMAC stiffness score， SF12-PCS （quality of life-physical health） score， SF12-MCS （quality of life-mental health） score， and TCM syndrome score. （2） Subgroup analysis. ① In terms of VAS score response rate， the response rate of the observation group was higher than that of the control group for subjects with baseline VAS score of （4， 5］， and the difference was statistically significant （P<0.05）. ② In terms of TCM syndrome score， for subjects aged ［56， 60］ and ［61， 65］， the decrease in total TCM syndrome score in the observation group was better than that in the control group， and the difference was statistically significant （P<0.05）. ConclusionTibetan medicine RYZBW has good clinical efficacy in improving WOMAC total score， VAS score response rate， WOMAC pain score， WOMAC function score， and TCM syndrome score for patients with initial and early KOA， which can fill the lack of Tibetan medicine RYZBW in the treatment of KOA and make a demonstration study for the inheritance and development of ethnic medicine.
