Objective To investigate the effects of Mawangdui exercise combined with neuro-muscular electrical stimulation(NMES)on pulmonary function,exercise capacity and quality of life in patients with chronic obstructive pulmonary disease(COPD).Methods A total of 96 COPD pa-tients were selected as the study subjects,and divided into control group(n=48)and intervention group(n=48).The control group received conventional pharmacological treatment,while the inter-vention group received Mawangdui exercise combined with NMES in addition to conventional pharma-cological treatment.The ratio of forced expiratory volume in the first second(FEV1)to forced vital capacity(FVC)(FEV1/FVC),the percentage of predicted FEV,(FEV1％),respiratory rate,re-sults of the 6-minute walk test(6MWT),scores of COPD Assessment Test(CAT),St.George's Respira-tory Questionnaire-I(SGRQ-I),Hospital Anxiety and Depression Scale(HADS)and Borg CR-10 Scale were analyzed in both groups before and after treatment.Results After 1 and 3 months of treatment,significant differences were observed in respiratory rate and 6MWT results between the two groups(P＜0.05).After 1 and 3 months of treatment,the FEV1％and FEV1/FVC in the intervention group were significantly higher than those at admission,and the FEV1％and FEV1/FVC after 3 months of treatment were significantly higher than those after 1 month of treatment(P＜0.05).Af-ter 3 months oftreatment,a significant difference in FEV1/FVC was observed between the two groups(P＜0.05).After 3 months of treatment,the CAT and SGRQ-I scores in the intervention group were significantly lower than those at admission(P＜0.05).After 3 months of treatment,the Borg CR-10 Scale score in the intervention group was significantly lowerthan that at admission and after 1 month of treatment(P＜0.05).After 3 months of treatment,a significant difference in SGRQ-I scores was observed between the two groups(P＜0.05).After 1 and 3 months of treatment,the HADS scores in the intervention group were significantly lower than those at admission,and the HADS score after 3 months of treatment was significantly lower than that after 1 month of treatment(P＜0.05).After 1 and 3 months of treatment,significant differences in HADS scores were ob-served between the two groups(P＜0.05).Conclusion Mawangdui exercise combined with NMES can improve exercise tolerance and pulmonary function,alleviate anxiety and depression,and thereby enhance the quality of life in COPD patients.

Objective:To explore the clinical characteristics of cardiotoxicity due to 5-hydroxytryptamine 3 receptor (5-HT 3) antagonists. Methods:Relevant databases at home and abroad (up to June 20, 2023) were searched and case literature of cardiotoxicity induced by 5-HT 3 receptor antagonist were collected. Relevant information of patients, medication status (drug name, usage and dosage, indication, combined drugs), occurrence of cardiotoxicity, evaluation of the association between 5-HT 3 receptor antagonists and cardiotoxicity, intervention measures and outcomes were extracted and analyzed descriptively and statistically. Results:A total of 23 case reports, 22 in English and 1 in Chinese, were enrolled in the analysis. There were 26 patients, 6 males and 20 females, and the age ranged from 8 to 60 years, with an average of 40 years. The reasons for drug use were perioperative antiemesis in 19 patients, chemotherapy antiemesis in 2 patients, and other reasons in 5 patients. Ondansetron was used in 19 patients, dolasetron in 4 patients, granisetron, tropisetron and palonosetron in 1 patient each. Except for 1 patient with overdose by self-medication, the dosage in 25 patients was within the recommended range in labels. A total of 50 case time of cardiotoxicity occurred in 26 patients, mainly including tachycardia (12 cases), electrocardiogram (ECC) changes (11 cases), bradycardia (9 cases), cardiac arrest (1 case), and myocardial infarction (1 case), etc. Twenty-one patients experienced cardiotoxicity after initial medication, of which 8 occurred immediately after the initial medication, 5 patients occurred after ≥2 times of medication. After the occurrence of cardiotoxicity, 26 patients stopped 5-HT 3 receptor antagonists successively, of which 24 stopped the drug immediately and received symptomatic treatments, 1 stopped the drug after 8 days of medication without other intervention, and 1 stopped the drug and received symptomatic treatment after the symptoms aggravated. After drug withdrawal and/or symptomatic treatments, the mentioned symptoms disappeared and ECC returned to normal in 25 patients. Of them, 22 patients had a recovery time of ≤48 hours, while the other 3 patients had their ECG returned to normal at 1 week, 2 weeks, and 2 months, respectively; one patient died due to ineffective treatment for ventricular fibrillation. Conclusions:The cardiotoxicity induced by 5-HT 3 receptor antagonists mostly occurs after the initial medication, and mainly manifests as tachycardia, bradycardia, ECG changes, etc. Most patients have a good prognosis after timely drug withdrawal and symptomatic treatments, and in severe cases, it can lead to death.

Objective: This study aimed to explore the role of SGK-1 in the occurrence of temporomandibular joint(TMJ) osteoarthritis(TMJ-OA). Methods: Sixteen rats were randomly divided into Control group(Control group) and TMJ-OA group(TMJ-OA group), and TMJ-OA group was injected with sodium iodoacetate(MIA) intra articular cavity while Control group was injected with 0.9% sodium chloride solution. Pain behavior was assessed by measuring the head withdrawal threshold(HWT) with a von-Frey apparatus. Hematoxylin-eosin(HE) and Safranin O-fast green stains were used to observe the histological structure changes of the condyle of TMJ-OA rats. Real-time PCR was performed to exam the expression levels of mRNA of SGK-1, MMP-13, IL-1β, COX-2 in mandibular condylar cartilage(MCC). HE stain was used to observe the histological structure changes of the trigeminal ganglion(TG) of TMJ-OA rats. Real-time PCR was performed to exam the expression levels of mRNA of SGK-1, COX-2 in TG. Results: MIA injection induced typical OA-like lesions in the TMJ within 28 days. Administration of MIA led to the significant decrease in HWT, disordered of the condyle cartilage and subchondral bone structure, demyelination aggravated of nerve fibers in TMJ rats. Compared with rats in Control groups, the expression levels of SGK-1 in MCC and TG of rats in TMJ-OA group were upregulated. Conclusion In the pathological process of TMJ-OA, SGK-1 may plays an important role not only in cartilage structural damage but also in pain transmission.

Antipyretic-analgesics are currently one of the most prescribed drugs in children.The clinical application of antipyretic-analgesics for children in our country still have irrational phenomenon, which affects the therapeutic effect and even poses hidden dangers to the safety of children.In this paper, suggestions were put forward from the indications, dosage form/route, dosage suitability, pathophysiological characteristics of children with individual differences and drug interactions in the symptomatic treatment of febrile children, so as to provide reference for the general pharmacists when conducting prescription review.

OBJECTIVE To investigate the effect of sodium ferulate (SF) on lipopolysaccharide (LPS)-induced preterm delivery and intra-uterine fetal death (IUFD). METHODS Pregnant Kunming mice were subcutaneously pretreated with SF (25 or 50 mg · kg-1) from gestational day (GD) 10 to GD 15 and with the single injection of LPS (150μg·kg-1, ip) on GD15.5. The incidence of preterm delivery and IUFD was observed. HE staining was used for uterine and placental histological evaluation. The levels of thiobarbituric acid reactive substances (TBARS) and reduced glutathione (GSH) as well as the activities of glutathione S-transferase (GST) and glutathione peroxidase (GSH-Px) were detected in the maternal liver, placenta, and fetal liver using commercial kits. Interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) levels in amniotic fluid were evaluated by enzyme linked immunosorbent assay. RESULTS For LPS group, the incidence of preterm was 47.8%, delivery time was (17.5 ± 1.3) d, and the pups′survival rate was only 42.6%. Compared with LPS-treated group, SF 50 mg · kg-1 group showed a lower incidence of preterm (14.3%, P<0.01), longer gestational days (18.4 ± 0.5, P<0.05), and a higher pups′survival rate (75.6%, P<0.01). SF 50 mg · kg-1 restored the LPS-induced GSH both in the maternal and fatal liver (a tendency without statistical significance), GST activity〔(163±82) kU·g-1 protein vs (95±90) kU·g-1 protein, P<0.01)〕in the placenta, TBARS content〔(2.5±0.4)μmol·g-1 protein vs (3.1±0.6)μmol·g-1 protein, P<0.01〕in the fetal liver, and TNF-αlevel〔(11±8) ng·L-1 vs (20±8) ng·L-1, P<0.01〕in the amniotic fluid. SF also attenuated LPS-induced placental congestion and neutrophil infiltra?tion in the uterus. CONCLUSION SF may protect against LPS-induced preterm delivery and IUFD, and anti-oxidation as well as anti-inflammation may contribute to these effects.

Objective To explore the clinical efficiency and safety of radiofrequency ablation combined with Tegafur,Gimeracil and Oteracil Porassium Capsules( S-1 capsules) for hepatocellular carcinoma.Methods Sixty HCC patients included in this study were underwent initial radiofrequency ablation and then they were di-vided into RFA+S-1 group and RFA control group according to the metronomic chemotherapy either with S-1 or not.The local tumor control and disease free survival outcome between the two groups were compared.Results Follow-up observation showed that the total control rate after 9 months′treatment was 93.3%in RFA+S-1 group vs.73.4%in RFA control group(P=0.038).During the 18 months of follow up,the median time for dis-ease free survival was 16.25 months in RFA+S-1 group vs.12.25 months in RFA control group( P<0.001) . One-year progression free survival rate in RFA group was 53.3%,which was significantly lower than the RFA+S-1 group(83.3%)(P=0.012).The major complication rate was 13.3%.No procedu rerelated death or severe complications occurred.Conclusion Metronomic chemotherapy with S-1 following initial radiofrequency ablation delays tumor progression and prolongs overall survival of patients with HCC tumors.

BackgroundThe relationship between lipids and coronary artery disease has been well established. However, this is not the case between lipids and heart failure. Ironically, high lipid levels are associated with better outcomes in heart failure, but the mechan-isms underlying the phenomenon are not fully understood. This study was performed to test the hypothesis that reduced intestinal lipid absorption due to venous congestion may lead to low lipid levels.MethodsWe collected data of clinical characteristics, echocardio-graph, and lipid profile in 442 unselected patients with congestive heart failure. Correlations between lipid levels[including total cho-lesterol(TCL), high-density lipoprotein cholesterol(HDL-C), low-density lipoprotein cholesterol(LDL-C), and triglycerides(TG)]and right ventricle end diastolic diameter (RVEDD), left ventricle end diastolic diameter (LVEDD), right atrium diameter (RA), left atrium diameter (LA), or left ventricle ejection fraction (LVEF) were analyzed using Pearson correlation and partial correlation. RVEDD, LVEDD, RA, and LA were indexed to the body surface area.ResultsThere was a significantly inverse correlation between TCL le-vels and RVEDD (r=-0.34,P<0.001) and RA (r=-0.36,P<0.001). Other lipids such as LDL-C, HDL-C, and TG had asimilar inverse correlation with RVEDD and RA. All these correlations remained unchanged after adjusting for age, gender, smoking status, physical activity levels, comorbidities, and medication use.ConclusionsLipid levels were inversely correlated to RVEDD in patients with congestive heart failure; however, because this was an observational study, further investigation is needed to verify our results as wellas identify a causal relationship, if any.

Objective To investigate the relationship of T peak-T end (Tp-Te) interval and Tp-Te interval disper-sion (Tp-Ted) in different periods of myocardial ischemia in patients with acute myocardial infarction (AMI), and to assess the clinical significance of Tp-Te and Tp-Ted for prediction of the ventricular arrhythmia (VA). Methods A total of 80 pa-tients with AMI were enrolled in the study. The sizes and changes of Tp-Te and Tp-Ted were observed during the acute phase and recovery phase in patients. The differences of Tp-Te and Tp-Ted were compared between ventricular tachycardia group (A group), ventricular premature beats group (B group) and non- ventricular arrhythmia group (C group). Results The values of Tp-Te and Tp-Ted were obviously longer in acute period [(125.22±17.70) ms and (54.76±13.26) ms] than those in recovery period[ (113.84±17.37) ms and (42.06±13.95)ms] (P<0.01). The values of Tp-Te and Tp-Ted were signifi-cantly longer in A group[ (134.82±19.56) ms and (62.00±15.19) ms] than those in B [(122.94±15.09) ms and (54.09±10.56) ms ]and C group [(110.09±15.21) ms and (45.27±9.85) ms]. The values were higher in B group than those of C group. Con-clusion The Tp-Te interval and Tp-Ted prolongated in acute phase than those of recovery phase in patients with AMI. Tp-Te interval and Tp-Ted can be used as an important index to predict VA in patients with AMI.

Objective To explore the effect of ω-3 fish oil on nutrition improvement and inflammatory reaction of patients with gastrointestinal tumor after operation.Methods 60 cases with gastrointestinal tumor were divided into control group(30 cases) and study group (30 cases),both groups were provided with parenteral nutrition treatment[ 104.6 kJ · kg-1 · d-1 ].Fish-oil fatty emulsion was given to the study group.The postoperative for the first day received half of the total energy and the total energy The remaining four days.Blood samples were gained on the morning of day 1,on the morning of day 3 and day 6 after operation respectively to measure albumin ( ALB),prealbumin (PA),total protein(TP),transferrin(TRF),the neutrophilic granulocyte count,lymphocyte count (TLC),serum C-reactive protein(CRP).Results Both groups of patients was comparable(all P ＜ 0.05 ).Both groups of patients was treated after five days of postoperative and ALB,TP,TRF were not significantly different.PA in both groups on day 6 was significantly increased,and the study group was higher than control group.there were statistical differences between them ( all P ＜ 0.05 ).The neutrophilic granulocyte count and CRP of both groups were significant reduced,and the study group was lower than control group.There were statistical differences between them( all P ＜0.05 ).Conclusion ω-3 fish oil on nutrition could improve nutritional quality and modulate inflammatory reaction of patients with gastrointestinal tumor after operation.
