Objective To investigate the clinical efficacy of Changqin No. 1 combined with Western therapy for severe traumatic brain injury and its effects on prognosis. Methods Totally 65 cases of severe traumatic brain injury were randomly divided into the treatment group (n=32) and the control group (n=33). The control group was treated with basic Western therapy (dehydration reduction of intracranial pressure, nutrition nerve, scavenging oxygen free radicals, improve cerebral circulation, nutritional support and maintain the internal environment stability, anti-infection, prevention and treatment of complications, hyperbaric oxygen). The treatment group was treated with Changqin No. 1 plus the basis of routine treatment, 1 dosage per day, 2 times stomach tube nasal feeding or blunt, for 14 d. One month after treatment, awake rate, awake time, the incidence of complications and MMSE in both groups were compared. Three months after treatment, the prognosis of two groups were compared by GOS. Results One month after treatment, the awake rate in treatment group was 77.4% (24/31) and 53.1% (17/32) in the control group, with statistical significance (χ2=4.089, P=0.043), and the death rate was 0. The awake time in the treatment group was significantly shorter than that of the control group (t=2.458, P=0.017). The incidence of pulmonary infection in the treatment group was lower than the control group (P=0.001). There was no statistical significance in urinary tract infection, epilepsy, liver and kidney dysfunction rate of the two groups (P>0.05). The number of awake case was 24 in the treatment group and 17 in the control group. The number of normal MMSE cognitive function was 3 in the treatment group and 2 in the control group, and the treatment group was better than the control group (Z=-2.205, P=0.027). Three months after treatment, the good prognosis was 58.08% (18/31) in the treatment group and 28.12%(9/32) in the control group, with statistical significance (χ2=5.763, P=0.016). Conclusion Changqin No. 1 combined with Western basic treatment can help patients with severe traumatic head injury awake early, reduce pulmonary infection complications, and improve the cognitive function of sober patients and improve the prognosis.

Objective To investigate the effect of aerobic exercise combined with routine rehabilitation therapy on cardiorespiratory exercise function and rehabilitation efficacy in stroke patients with hemiplegia.Methods Thirty consecutive stroke patients with the first-ever hemiplegia were enrolled prospectively.They were randomly assigned to an experimental group (n=13) or a control group (n=13) according to the random number table (n=15 in each group).Four patients withdrew,and finally 26 patients completed the study (n=13 in each group).The two groups of patients were given routine rehabilitation therapy.On the basis of routine rehabilitation therapy,the experimental group was also treated with aerobic exercise training,once a day,30 min each time for 4 weeks.The evaluations of cardiopulmonary exercise tests were performed on both groups before treatment and after 4 weeks of treatment (peak oxygen uptake [VO2peak]),anaerobic threshold [AT],peak minute ventilation [VEpeak]),and motor function (Fugl-Meyer assessment scale [FMA],activities of daily living (Barthel index [BI]) were performed.The differences between the two groups before and after treatment were compared.Results (1)Cardiopulmonary exercise test results:Compared with before treatment,VO2peak,AT,and VEpeak were increased significantly (16±4 ml/[kg·min] vs.13±3 ml/[kg·min],12.9±2.5 kg·min vs.10.0±2.7 ml/[kg·min],41±12 L/min vs.34±9 L/min,t=9.668,4.328,and 3.662,respectively,all P<0.01).There were no significant differences in VO2peak,AT,and VEpeak (14±4 ml/[kg·min] vs.14±4 ml/[kg·min],11.8±2.6 ml/[kg·min] vs.11.5±2.9 ml/[kg·min],29±8 L/min vs.28±6 L/min) in patients of the control group between before treatment and after treatment.There were no significant differences (t=0.863,0.583,and 0.314,respectively,all P>0.05).The differences in VO2peak,AT,and VEpeak in the patients of the control group before and after treatment were 0.4 (0.2,0.6),0.1 (-0.5,0.7 ml/kg·min) and 0 (-2.5,5.0 L/min),respectively.The differences of VO2peak,AT,and VEpeak in patients of the experimental group before and after treatment were 3.0 (2.2,3.9 ml/[kg·min],2.7 (1.8,5.3 ml/[kg·min],and 7.0 (1.0,13.0 L/min),respectively.There were significant differences in VO2peak,AT,and VEpeak before and after treatment between the two groups (Z=4.287,3.721,and 2.236,respectively,P<0.05).(2) FMA score and BI evaluation results:Compared with before treatment,the FMA score and Barthel index after treatment in patients of the experiment group were 70±24 vs.52±28 and 78±20 vs.60±28 respectively,t=4.076 and 4.239 respectively,P<0.01).Compared with before treatment,the FMA score and BI in the control group after treatment were improved significantly (68±25 vs.60±27 and 69±22 vs.59±26 respectively,t=3.168 and 5.436 respectively,all P<0.05).The FMA score and the difference of BI in the control group before and after treatment were 5.0 (2.0,12.0) and 10.0 (5.0,15.0) respectively,and those of the experimental group before and after treatment were 10.0 (4.5,32.0) and 11.0 (10.0,27.5) respectively,and there were no significant differences between the two groups (Z=1.393,1.352,all P>0.05).Conclusion On the basis of routine rehabilitation therapy,stroke patients with hemiplegia increasing aerobic exercise training may improve their cardiopulmonary exercise function.

Objective To investigate the relationship between inflammation and blood coagulation function in the patients with acute exacerbation of chronic cor pulmonale (AECCP) and discuss the potential mechanism and influence on the patients. Methods The present study was based on 30 healthy controls and 141 cases of AECCP in our hospital from January 2011 to June 2014.Levels of white blood cell (WBC), neutrophil (NEUT), high-sensitivity C-reactive protein (hs-CRP, Complement 3 (C3), prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (FIB) and thrombin time (TT) in the patients were determined. Results Compared with the healthy controls, the patients had higher levels of WBC, NEUT, hs-CRP, PT, APTT, FIB, TT (all P < 0.001) and lower level of C3 (P < 0.001). Significant positive correlations were found between the levels of WBC, NEUT and FIB (r = 0.196 and r = 0.199, both P < 0.05); hs-CRP and APTT, FIB(r = 0.234, P < 0.01 and r = 0.466, P < 0.001); C3 and FIB(r = 0.466, P < 0.001), and significant negative correlations were observed between the levels of C3 and PT, APTT, TT (r=-0.258, P<0.01;r=-0.279, P < 0.01 and r = -0.168, P < 0.05, respectively). Compared with the survival patients, the cases of death had higher levels of WBC and NEUT (both P < 0.01). The area under receiver operating characteristic curve of WBC and NEUT, predicting the prognosis, was 0.666 (95% CI 0.552, 0.780; P < 0.01) and 0.695 (95% CI 0.558, 0.801; P = 0.001) respectively. Conclusions Inflammation and blood coagulation function disorder usually coexist in the patients with AECCP, and are closely associated with the severity. Levels of both WBC and NEUT can be used as prognosis predictors for the patients.

Background Domestic waste classification is one of the major livelihood projects in China. With the introduction of the Shanghai Household Waste Management Regulation in 2019, the work of domestic waste classification has been carried out nationwide, yet its potential risks especially those derived from microorganisms are not clear. Objective To investigate the microbial characteristics of the domestic waste in typical residential areas in Shanghai, and provide a theoretical basis for health protection during the domestic waste classification process in Shanghai and throughout China. Methods Dry and wet waste from a typical residential community in Shanghai were collected during 2019–2020. Microbial colonies were counted in domestic waste and analyzed for growth patterns. Then through 16S rRNA sequencing using lllumina PE250, hierarchical clustering analysis was conducted to reveal the similarity and dissimilarity of community compositions in different domestic waste groups, alpha diversity was estimated to reflect the richness and diversity of bacterial communities, principal co-ordinates analysis of unweighted UniFrac distance was performed to estimate the beta diversity, and linear discriminant analysis effect size (LEfSe) was used to find features differentially represented among domestic waste groups. Results In the chosen typical residential community of this study, the numbers of microorganisms in waste were quite different, with lower numbers of microorganisms in dry waste than the numbers in wet waste. In addition, different growth curves of microorganisms were shown for different seasons, and the peak baterial colony numbers were 200 CFU·cm⁻², 6×10⁵ CFU·mL⁻¹, 10 CFU·cm⁻², and 2×10⁶ CFU·mL⁻¹ for summer dry waste, summer wet waste, winter dry waste, and winter wet waste, respectively. The results of 16S RNA demonstrated significant differences in α and β diversity indicators among different waste groups, and the difference in waste classifications was larger than the difference of the same classification of waste in different seasons. The main compositions of bacterial colonies in domestic waste was Proteobacteria, followed by Firmicute and Bacteroidota. The clustering analysis showed that the microbial composition in summer dry waste was close to that in winter dry waste, while other groups were quite different. In total 48 differential bacterial taxa were found at the level of genus including Pseudomonas and Pantoea. Conclusion Different seasons and different classifications of domestic waste present varied microbial characteristics, with different potential pathogenic microorganisms. Together with other related studies, we suggest that different measures should be taken for different domestic wastes to prevent and control the health hazards associated with waste classification.

Results After the prevention and control guideline was implemented, the positive rate of blood stasis in the bedridden elderly patients rose from 6.3% (7/112) to 15.2%(15/99), while the incidence rate of DVT dropped from 8.9% (10/112)to 2.0%(2/99) (χ2=4.458, 4.676;P＜ 0.05). Conclusions The prevention and control guideline based on the DVT prevention and management guideline can reduce the risks of DVT in bedridden elderly inpatients.

Air pollution is a global issue that threatens human health. In recent years, more and more studies have found that air pollution is closely related to the occurrence of depression. As a serious neuropsychiatric disorder whose incidence is rising rapidly year by year, depression has become an invisible killer of public health. At present, studies on the correlation between air pollution and depression are still very limited, and the underlying molecular mechanisms by which air pollution affects depression are not clear. Based on existing epidemiological and toxicological studies, this paper provided a review of the relationship between air pollution and depression and the possible biological mechanisms, with a focus on the relationship between air pollution and depression indicators and the possible factors affecting depression such as types of air pollutants, exposure time, age and health status of study subjects. In addition, the potential roles of neuroinflammation, oxidative stress, neurogenesis, and apoptosis in the process of air pollution-induced depression were also discussed in order to provide a scientific basis for the prevention and treatment of air pollution-induced depression.
