Objective To observe the therapeutic effect of minimally invasive evacuation of intracerebral hematoma in dog model of cerebral hemorrhage by using Purdy score, serum levels of neuron-specific-enolase (NSE) and numbers of perihematomal apoptotic cells. Method Twenty dogs were selected to prepoxe the model of cerebral hemorrhage, and they were randomly divided( random number) into minimally invasive treatment group and control group. Minimally invasive procedures were performed to evacuate the hematoma in minimally invasive treatment group in 6 hours after the models were established. The dogs of control group only received medical treatment. Purdy score and serum levels of neuron-specific-enolase were determined on 1,3,5,7 days after the evacuation of the hemotoma and apoptotic cells were counted after the dogs were sacrificed at 7 days after operation. All the results were compared with control group. Purdy score and serum levels of neuron-specific-enolase were compaired with variance analysis of repeated measurement design and apoptotic cells was compared with variance analysis of factorial design,the difference of the two groups showed with q test. P <0.01 showed the difference was significant. Results The Purdy scores in minimally invasive treatment group were 6.3 ± 1.702, 5.8 ± 1. 685,4.2 ± 1.762 and 4.1 ± 1.875 on 1,3,5 and 7 day after evacuation of the hematoma, significant difference was observed as compared with the control group(8.9 ± 1.632, 8.6± 1.342, 7.8±1.335, 7.9±1.468, P <0.01).The serum levels of neuron-specific-enolase were 0.632 ± 0.077, 0.721±0.771, 0.549±0.124 and 0.430 ±0.136 respectively in minimally invasive treatment group, while in the control group were 0.934 ± 0. 064, 0. 997 ±0.075, 0.986 ± 0.042, 0.874 ± 0.165, significant differences in serum levels of neuron-specific-enolase were found between the two groups(P < 0.01). The perihematomal apoptotic cells in minimally invasive treatment group(37.4 cells) was decreased significantly as compared with the control group(88.6 cells), with P < 0.01.Conclusions Minimally invasive procedures for evacuation of intracerbral hematoma might significantly reduce the neurological deficit score and decrease the serum neuron-specific enolase levels and numbers of apeptotic neurons.

Objective To evaluate the efficacy of integrated traditional Chinese medicine(TCM)and western medicine in treatment of acute exacerbations of chronic obstructive pulmonary disease(AECOPD)combined with respiratory failure,TCM syndromes of spleen-kidney-yang deficiency and phlegm-dampness by comparison between the integrated therapy and simple western therapy in treatment of the disease. Methods 160 patients with AECOPD combined with respiratory failure,spleen-kidney-yang deficiency and phlegm-dampness syndrome in the intensive care units(ICU)of Affiliated Hospital of Chengdu University of TCM and other four hospitals were randomly allocated into two groups in this double-blinded,multicenter,prospective,randomized,controlled trial. In the control group (78 cases),western medicine and placebo were given to the patients,and in the treatment group(82 cases), conventional western medicine plus fei-shuai mistura 25 mL were administered,four times per day,the therapeutic course lasting for 2 weeks in both groups. The all-cause mortality,respiratory failure-cause mortality,improvement of modified Medical Research Council(mMRC)Dyspnea Scale grades,6 minutes walk distance(6MWD),the forced expiratory volume in 1 second/forced vital capacity(FEV1/FVC)were observed in the 28 days after the end of treatment. Results In the comparisons between the control and treatment groups,there were no statistical significant differences in the all-cause mortality〔54.87%(45/82)vs. 64.10%(50/78)〕and the cases of FEV1/FVC(both P>0.05)in the 28 days after the end of treatment;the 28 day respiratory failure-cause mortality was significantly decreased〔19.51%(16/82)vs. 33.33%(26/78),P<0.05〕,the number of patients with mMRC Dyspnea Scale grades (1-2)was obviously increased(22 cases vs. 7 cases,P<0.05),and the number of patients with 6 MWD grades (4-6)was markedly enhanced in the treatment group(21 cases vs. 8 cases,P<0.05). Conclusions The integrated TCM and western medicine has better therapeutic results in improvement of the patients' degree of dyspnea, 6 MWD and respiratory failure mortality than simple treatment with western therapy for treatment of patients with AECOPD combined with respiratory failure, spleen-kidney-yang deficiency and phlegm-dampness syndrome. However,in regard to the effect on pulmonary function and all cause mortality,the integrated therapy for treatment of such patients in short term has no significant effect.

Objective To evaluate the present development and status of quality control for intensive care unit (ICU) in Sichuan Provincial traditional Chinese medicine (TCM) hospitals including integrated traditional Chinese and western medicine hospitals and ethnic hospitals, and to provide practical references for improving the service quality of ICU. Methods Supervisory Group of Sichuan Provincial Critical Care Medicine Quality Control Center of TCM was established in September 2018. From September 8th to 17th, 2018, according to the Scoring Criteria of Quality Control and Supervision Project of TCM for Critical Care Medicine, a 10-day quality control professional guidance was hand out to TCM hospitals with independent ICU in Sichuan Province. The service level of different aspects of hospital quality control was evaluated and ranked from equipment and resource support, medical team, service capacity and level, ward quality, completion of critical care core indicators, completion of quality control of TCM, development of new technologies, diagnosis and treatment schemes for dominant diseases. Results There were 52 TCM hospitals across the province that had an ICU. Thirty-three hospitals were third-class (63.5%), while the rest 19 hospitals were second-class (36.5%). Province-level, city-level and county-level hospitals were accounted for 9.6% (5/52), 38.5% (20/52), and 51.9% (27/52), respectively. Average bed ratio of ICU was 1.8%. Doctor-bed and guard-bed ratios were 0.71∶1 and 2.0∶1, respectively. The average annual admission rate of patients and the average daily admission rate of beds were higher, which were basically 1%. Ward quality was high; the incidence of nosocomial infection was controlled below 10%. Compliance rate of septic shock bundle treatment was high. The incidences of ventilator-associated pneumonia (VAP), catheter-related bloodstream infection (CRBSI) and catheter-associated urinary tract infection (CAUTI) were 0.45%, 0.22%, and 0.30%, respectively. Participation rate of TCM was about 83.4%. Average number of new technologies was about 4.4. Average number of disease schemes was about 2.62. Conclusions ICU of Sichuan Provincial TCM hospitals reaches the standard level in service capacity and level, ward quality, critical medicine quality control, and participation rate of TCM treatment. Improvements are required for other prospects, including department scale, medical personnel allocation, new technical development, diagnosis and treatment schemes of dominant diseases.

Objective To analyze the core functional component groups(CFCG)in Yinchenhao Decoction(YCHD)and their possible pathways for treating hepatic fibrosis based on network pharmacology.Methods PPI data were extracted from DisGeNET,Genecards,CMGRN and PTHGRN to construct a weighted network using Cytoscape 3.9.1.The data of the chemical components in YCHD were obtained from Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP),and the potential active components and targets were selected using PreADMET Web server and SwissTargetPrediction.A fusion model was constructed to obtain the functional effect space and evaluate the effective proteins to identify the CFCG followed by GO and KEGG pathway enrichment analyses for all the targets.In cultured human hepatic stellate cells(LX-2 cells),the cytotoxicity of different compounds in YCHD was tested using CCK-8 assay;the effects of these compounds on collagen α1(Col1a1)mRNA expression and the pathways in 20 ng/mL TGF-β1-stimulated cells were analyzed using RT-qPCR and Western blotting.Results A total of 1005 pathogenic genes,226 potential active components and 1529 potential targets in YCHD and 52 potential targets of CFCG were obtained.Benzyl acetate,vanillic acid,clorius,polydatin,lauric acid and ferulic acid were selected for CCK-8 verification,and they all showed minimal cytotoxicity below the concentration of 200 μmol/L.Clorius,polydatin,lauric acid and ferulic acid all effectively inhibited TGF-β1-induced LX-2 cell activation.At the concentration of 200 μmol/L,all these 4 components inhibited PI3K,p-PI3K,AKT,p-AKT,ERK,p-ERK,P38 MAPK and p-P38 MAPK expressions in TGF-β1-induced LX-2 cells.Conclusion The therapeutic effect of YCHD on hepatic fibrosis is probably mediated by its core functional components including benzyl acetate,vanillic acid,clorius,polydatin,lauric acid and ferulic acid,which inhibit the PI3K-AKT and MAPK pathways in hepatic stellate cells.
