ABSTRACT
ObjectiveThrough a randomized， double-blind， double-simulation， positive-control， multicenter design， this study aimed to analyze the relationship between the dosage， efficacy， and safety of Pudilan anti-inflammatory oral liquid in treating acute pharyngitis/tonsillitis in adults caused by bacterial infection and validate the regulatory effect of Pudilan anti-inflammatory oral liquid on inflammatory markers such as serum amyloid A （SAA）， C-reactive protein （CRP）， white blood cells （WBC）， neutrophil percentage （NE%）， and erythrocyte sedimentation rate （ESR）， thereby exploring the feasibility of using Pudilan anti-inflammatory oral liquid as a substitute for antibiotics in the treatment of infectious diseases and providing a basis for rational clinical medication. MethodUsing a stratified randomized， double-blind， double-simulation， positive-control， multicenter design， 220 participants were enrolled from nine centers. The participants were randomly divided into three groups at 1∶1∶1 — a Pudilan anti-inflammatory oral liquid 20 mL group （73 cases）， a Pudilan anti-inflammatory oral liquid 10 mL group （73 cases）， and a control group （amoxicillin group， 74 cases）. The treatment course was 7 days. The study observed parameters including the total effective rate of sore throat， onset and disappearance time of sore throat， health status score， treatment time， and inflammation markers. Result①Dataset division： The 211 cases were included in the full analysis dataset （FAS）， 208 cases were included in the per-protocol dataset （PPS）， and 218 cases were included in the safety dataset （SS）. ② Efficacy evaluation： There were statistically significant differences （P<0.05） in the comparison of the three groups regarding the total effective rate of sore throat， disappearance time of sore throat， and health status. Both the 20 mL and 10 mL groups were non-inferior to the control group， and there was a statistically significant difference between the 20 mL and 10 mL dosage groups （P<0.05）. There was no statistically significant difference in the comparison of onset time of sore throat among the groups. CRP， WBC， and NE% of patients in all three groups significantly decreased on the 7th day of treatment compared with those before treatment （P<0.01）. ③Safety evaluation： Adverse events mainly occurred in various examination indicators. There were no statistically significant differences in the comparison between groups， and no adverse reactions or serious adverse events occurred. ④Economic evaluation： The increased cost of the 10 mL and 20 mL dosage groups was entirely justified as compared with that in the control group. When comparing the 10 mL and 20 mL dosage groups， the 10 mL dosage group was deemed less advantageous. ConclusionPudilan anti-inflammatory oral liquid can be used alone as an alternative to antibiotics in the treatment of acute pharyngitis/tonsillitis caused by bacterial infection. It demonstrates good safety and can lower inflammation markers such as CRP， WBC， and NE%， suggesting its potential to reduce the body's inflammatory response. Its mechanism of action may be related to its multi-target regulatory mechanism.
ABSTRACT
Objective:To investigate the application effect of the blended teaching model of "intelligent teaching" and "wisdom learning" in the practice teaching of integrated traditional Chinese and Western medicine in internal medicine.Methods:According to the principle of randomization, 54 interns in Class 1 of integrated traditional Chinese and Western medicine in the grade of 2019 were selected as control group and received traditional teaching, and 56 interns in Class 2 were selected as observation group and received blended teaching with "intelligent teaching" and "wisdom learning". After 6 months of internship, the two groups were compared in terms of the scores of theoretical assessment (basic theoretical knowledge and professional theoretical knowledge), clinical practice ability [Leicester Assessment Package (LAP)], and degree of satisfaction with teaching. SPSS 17.0 was used to perform the t-test and the chi-square test. Results:At the end of internship, compared with the control group, the observation group had significantly higher score of basic theoretical knowledge (41.53±3.42 vs. 38.71±3.38, P<0.05), score of professional theoretical knowledge (39.49±3.14 vs. 37.85±3.07, P<0.05), LAP score (84.32±6.65 vs. 78.46±6.17, P<0.05), and degree of satisfaction with teaching ( P<0.05). Conclusion:For interns majoring in integrated traditional Chinese and Western medicine, the blended teaching model of "intelligent teaching" and "wisdom learning" can strengthen their mastery of theoretical knowledge, enhance their clinical practice ability, and improve their degree of satisfaction with teaching.
ABSTRACT
Bronchial asthma is a common heterogeneous chronic inflammatory disorder of airways characterized by airway hyperreactivity， mucus hypersecretion， and airflow obstruction. The incidence of asthma has been on the rise worldwide， and about 45.7 million adults in China suffer from asthma. Asthma is considered a costly disease， resulting in a significant economic and social burden. microRNAs （miRNAs） are long noncoding RNAs that regulate gene expression. They play a role in asthma through their activity in multiple immune and non-immune cell subsets. They impact multiple facets of critical cell function including cell survival， proliferation， and differentiation， which in turn induce the occurrence of airway spasm， mucus hypersecretion， and asthma symptoms. Traditional Chinese medicine has a long history in the treatment of asthma. Over the past a few decades， a growing number of herbs have proven effective in treating asthma in clinical trials or asthma inflammation in animal models. Chinese medicine has the features of multiple components and multiple targets. Evidence suggests that Chinese medicine and components of Chinese medicine can regulate immune homeostasis， improve airway inflammation and airway remodeling by modulating microRNA expression for asthma treatment. However， there is a lack of systematic and detailed reviews on the regulation of asthma-related microRNA expression by Chinese medicine. The article aims to review the correlation between microRNAs and asthma in animal experiments and clinical trials in recent years， as well as the mechanism of microRNA regulation by Chinese medicine in the treatment of asthma， with the intention of providing a reference for basic research and clinical application.
ABSTRACT
Objective To analyze the clinical features and risk factors of death in pediatric trauma,in order to provide preventing strategies and reduce mortality.Methods A retrospective study of 7936 traumatic children admitted to the emergency department of our hospital from April 2014 to March 2016 was conducted.We retrospectively summarized the clinical features and Logistic regression analysis was used to analyze the risk factors of death in children with trauma.Results Compared to females,male patients contributed higher percentages(1.73∶1).There were more migrant children(5535 cases) than local ones(2 401 cases)(χ2=14.314,P＜0.05).Children in infancy stage(2 024 cases)and toddler period(3 097 cases) were more than in the other periods.Limb[41.9%(3 324/7 936)] and skin injuries[38.5%(3 058 324/7 936)] were the most common.Children trauma causes varied with age,fall,tumble and traffic accidents were common causes of children trauma.Pediatric trauma score of surviving group(n=1933),death group(n=5),general ward group(n=1852) and ICU group(n=86) were 8.53± 2.17,3.17± 1.29,9.72± 1.25,5.23± 1.84,respectively.Shock decompensation,mechanical ventilation,Glasgow coma scale ≤7 and pediatric trauma score＜8 were the risk factors which caused the death of trauma.Conclusion Parents should improve the security sense,strengthen the care of children and obey the traffic rules to reduce the rate of children trauma.Clinicians should pay attention to shock decompensation,mechanical ventilation,Glasgow coma scale and pediatric trauma score in order to identify critically ill patients in early stage and improve the success rate of rescue.
ABSTRACT
Objective To study the effect of the low free radical cigarettes (test cigarettes) on the blood biochemical parameters,lung and polychromatophilic red cell micronucleus in rats. Methods 36 SD rats were randomly divided into the blank control group,the comparison smoke group and the experimental smoke group (low free radical cigarettes),12 in each. Let the rats smoke passively for 30 day,daily 12 cigarettes,then the determination of blood biochemical parameters and the polychromatophilic red cell micronucleus rate in the bone marrow,the pathological examination of the trachea and the lung tissues were conducted. Results Compared with the blank control,no significant changes were seen in the blood biochemical parameters and the polychromatophilic red cell micronucleus rate. The pathological examination of the lung tissues indicated that the pathological changes in the experimental smoke group were slight compared with the comparison smoke group. Conclusion No seriously adverse effects of low free radical cigarettes on the lung tissues of rats have been seen in the present study,that indicates that maybe the low free radical cigarette has an advantage in the health safety.
ABSTRACT
Objective To investigate appropriate use of radiofrequency thermal ablation (RFA) in treatment of liver cancer.Methods Fouty-one patients with hepatic cancer were entered into two trials. The liver tumors were treated with percutaneous radiofrequency ablation (PRFA) or intraoperative radiofrequency ablation (IRFA). All patients were followed up postoperatively to assess complications, treatment response, and local recurrence of tumor.Results PRFA and IRFA were performed on 32 tumors in 18 patients and 43 tumors in 23 patients, respectively. Treatment-related complications occurred in 6 of the 18 patients treated with PRFA (33.3%). In contrast, there was only 1 complication after IRFA (4.3%, P
