Objective To systemically evaluate the clinical therapeutic effect of combined traditional Chinese medicine (TCM) and western medicine for treatment of acute heart failure by Meta analysis. Methods The America National Library PubMed and China Biomedical Literature Data System (SinoMed), China National Knowledge Infrastructure (CNKI), VIP Data Resource, Wanfang Data Resource, Chinese TCM Database Retrieval System were searched from 1990 to May 2014 to identify the formally published randomized controlled trials (RCTs) in which the effects of combined TCM and western medicine (experiment group) or simple western medicine (control group) for treatment of patients with acute heart failure were reported. The Cochrane system 4.2.2 quality evaluation standard in Evaluation Handbook was applied to assess the methodological quality of literature. The Cochrane Collaboration's RevMan 5.2 software was used to seek the literatures consistent to the criteria of enrolling into the study for Meta analysis. Results There were 18 RCTs, and all together 1 374 cases were included in the data. The grade of methodological quality of the enrolled studies was of high migration. Meta analysis showed: compared with the control group, the clinical efficacy in experimental group was significantly higher [odds ratio (OR) = 5.04, 95% confidence interval (95%CI): 3.31 - 7.69, P < 0.000 01]; the level of type B natriuretic peptide (BNP) was significantly reduced [standardized mean difference (SMD) = -1.31, 95%CI: -1.78 to -0.83, P<0.000 01];left ventricular ejection fraction (LVEF) was significantly increased (SMD=0.79, 95%CI:0.52-1.07, P < 0.000 01); the therapeutic effect on TCM syndrome was significantly elevated [categorical variables: relative risk (RR) = 1.30, 95%CI: 1.06 - 1.59, P = 0.01; quantitative variables: mean difference (MD) = -1.67, 95%CI: -2.48 to-0.86, P<0.000 1] and cardiac diastolic function was significantly improved (SMD=0.64, 95%CI:0.05-1.24, P<0.05). Conclusions The clinical therapeutic effects of combined TCM and western medicine are significantly higher than those of simple western medicine for treatment of patients with acute heart failure. However, the low quality of the reports involved in this study limits the reliability of this conclusion.

Objective To investigate the effect of penehyclidine hydrochloride combined with low tidal volume ventilation on lung function in patients with lower abdominal operation.Methods Sixty elderly patients who underwent elective lower abdominal operation were divided into three groups by random digits table method:the conventional tidal volume group (group A),penehyclidine hydrochloride combined with conventional tidal volume group (group B) and penehyclidine hydrochloride combined with low tidal volume group (group C),20 cases in each group.The patients in group B and group C were given penehyclidine hydrochloride 0.01 mg/kg before induction of anesthesia.The patients in group A were given equal volume of saline.After induction of anesthesia and mechanical ventilation modes:the patients in group A and group B were given tidal volume 10 ml/kg,the patients in group C were given tidal volume 6 ml/kg.After mechanical ventilation in anesthetized (T1),1 h after anesthesia (T2),2 h after anesthesia (T3),8 h after anesthesia (T4),24 h after anesthesia (T5),the level of tumor necrosis factor alpha (TNF-α),interleukin-6 (IL-6),pH,arterial partial pressure of oxygen (PaO2),arterial partial pressure of carbon dioxide (PaCO2),the calculation of oxygenation index (PaO2/FiO2) were measured and compared.The pulmonary complications after operation 1 day were recorded.Results The level of TNF-α,IL-6 in three patients at T1 had no significant difference (P ＞ 0.05).The level of TNF-α,IL-6 at T2-5 in group C were significantly lower than those in group A and group B (P ＜ 0.05).Compared with group A and group B,the level of PaO2 and PaO2/FiO2 at T2-5 were increased in group C (P ＜ 0.05).None pulmonary complications were occurred in three groups.Conclusions Penehyclidine hydrochloride combined with low tidal volume ventilation may improve arterial oxygen in patients with lower abdominal operation,reduce the lung injury induced by mechanical ventilation,protective effect on lung function.

Objective To observe the effect of monosialoteterahexosyl ganglioside (GM1) combined with Shuxuening injection on nerve function in patients with acute cerebral infarction (ACI) and its mechanism.Methods A total of 94 patients with ACI admitted to the Department of Neurology in Xiangyang First Peoples' Hospital Affiliated to Hubei Medical College from January 2013 to June 2016 were enrolled,and they were divided into two groups by random number table,each group 47 cases.The patients in two groups were all given conventional western medicine treatment;The patients in one group (single group) were treated by intravenous (Ⅳ) drip of GM1,100 mg once a day;and the patients in another group (combined group),by above GM1 Ⅳ drip combined with Shuxuening intramuscular injection,once 2 mL,twice a day;the therapeutic course in two groups was 14 days.Before and after treatment,the changes of China stroke clinical neurological impairment score (CSS score),glasgow coma score (GCS),nerve factor,oxidative stress index and hemodynamics index of two groups were observed.Results Compared with those before treatment,after treatment the CSS score,the levels of neuron specific enolase (NSE),and malondialdehyde (MDA) were significantly lower,while the GCS score,the levels of nerve growth factor (NGF),neurotrophic factor (NTF),maximum blood flow velocity (Vmax),minimum blood flow velocity (Vmin),mean blood flow velocity (Vmean),mean blood flow quantity (Qmean),glutathione peroxidase (GSH-Px),catalase (CAT) and superoxide dismutase (SOD) were all significantly higher in the combined group (all P ＜ 0.05).After treatment,the CSS score,levels of NSE and MDA in the combined group were significantly lower than those of the single group [CSS:11.20 ± 1.78 vs.16.24 ± 1.95,NSE (μg/L):13.17± 1.00 vs.17.68 ± 1.84,MDA (μmol/L):4.14±0.49 vs.5.61 ±0.50,all P ＜ 0.05],GCS score,NGF,NTF,GSH-Px,CAT,SOD,Vmax,Vmin,Vmean and Qmean of the combined group were all significantly higher than those of the single group [GCS:13.68± 1.85 vs.12.01±1.76,NGF (ng/L):88.10±8.83 vs.68.13±7.16,NTF (pg/L):5.13±0.38 vs.3.71±0.30,GSH-Px (U/L):128.13±8.07 vs.103.90±6.58,CAT (U/L):25.74±2.15 vs.19.43± 1.84,SOD (μU/L):94.36±8.00 vs.77.29±7.34,Vmax (cm/min):48.23±3.36 vs.43.17±2.88,Vmin (cm/'min):8.11±0.76 vs.6.85 ± 0.64,Vmean (cm/min):18.69 ± 1.37 vs.15.60 ± 1.24,Qmean (mL/min):9.10 ± 0.74 vs.7.79 ± 0.66,all P ＜ 0.05].Conclusions GM1 combined with Shuxuening injection can improve nerve function in patients with ACI by improving brain blood flow,secreting neurotrophic related factors and inhibiting oxidative stress reaction,thus it has important clinical significance for repairing the damaged nerve function.

OBJECTIVE: To study the mechanisms of Tongxia Huayu Decoction (a Chinese herbal decoction for purgation and removing blood stasis) in prognostic improvement for severe acute pancreatitis by early intervention on pancreatic microcirculatory disturbance. METHODS: Fifty-three patients with severe acute pancreatitis were divided randomly into treatment group (n=28) and control group (n=25). Tongxia Huayu Decoction was given to the patients in treatment group in addition to the normal treatment in control group for one week. The clinical symptoms and signs, hemodiastase, urinary amylase, C-reactive protein (CRP) and endothelin (ET) of the patients in the two groups before and after treatment were observed and detected. RESULTS: The total response rate of the treatment group was 98.4%, while that of the control group was 80%, with significant difference between them (P<0.05). There was no significant difference of the contents of hemodiastase, urinary amylase, CRP and ET between the two groups before treatment, while they were significantly decreased after treatment (P<0.01) with more obvious change in treatment group (P<0.01). CONCLUSION: Tongxia Huayu Decoction brings satisfied therapeutic effect on severe acute pancreatitis. The mechanisms may associate with its reducing function on ET releasing so as to inhibit the pancreatic microcirculatory disturbance and acinar cell injury induced by ET.

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.

In the history of modern medicine, the operating room has undergone a series of evolution since its origin. This article explains the etymology of operating theatre and illustrates the history of its origin and development. Transformed from anatomical amphitheatre and currently to surgical amphitheatre to modern operating room, the design purpose of operating room has changed from demonstration and teaching to elimination of infection and and to the pursuit of higher aseptic principles nowadays. The promotion of antisepsis and advent of anaesthesia changed the operating room in the past. In the future, the renewal of scientific ideas and technological progress will continue to promote the evolution of the form and content of the operating room and keep it moving towards medical humanism.

OBJECTIVE:To investigate the inhibitory effects mechanism of scallop skirt glycosaminoglycan(SS-GAG)on inju-ry in human umbilical vein endothelium cells (HUVEC). METHODS:In the test,there was a negative control group,a model group and the groups of SS-GAG at high,middle and low concentrations(mass concentrations of 200,100 and 50 mg/L respective-ly). The cells in latter 3 groups were cultured in SS-GAG at different mass concentrations for 12 h,and then in 50 μmol/L oxidized low-density lipoprotein(OX-LDL)for 24 h. MTT method was used to detect cell viability and the activity of lactic dehydrogenase (LDH),the flow cytometer to determine the level of reactive oxygen species (ROS),real-time fluorescence quantitative poly-merase chain reaction (RT-PCR) to detect mRNA expression of lectin-like oxidized low-density lipoprotein receptor 1 (LOX-1), and Western blot to detect NOX4 protein expression. RESULTS:Compared to the cells in the negative control group,those in the model group demonstrated lower viability,higher activity of LDH,higher level of ROS,and stronger expressions of LOX-1 mRNA and NOX4 protein. There was statistical significance (P<0.01). Compared to the cells in the model group,those in the groups of SS-GAG at high,middle and low concentrations showed higher viability,lower activity of LDH,lower level of ROS and weaker expressions of LOX-1 mRNA and NOX4 protein. There was statistical significance (P<0.01). CONCLUSIONS:SS-GAG can protect HUVEC to some degree by a mechanism which may be related to inhibiting ROS production via LOX-1/NOX4 pathway and relieving oxidative stress injury.

Objective To explore the relationship between the levels of Cu, Fe, Mn, Zn in serum and Parkinson disease (PD). Methods A total of 40 patients with PD (PD group) and 40 control subjects (control group)were enrolled in this study. Serum levels of Mn were measured by graphite atomic absorption, and Cu ,Fe, Zn were measured by inductively coupled plasma(ICP)mass spectrometry. Resudts There were significantly increase in the levels of Mn and Fe in PD group than those in control group [(0.269±0.326) μ mol/L vs (0.125±0.054) μmol/L, P< 0.05, (1.512±0.949) μmol/L vs (0.676±0.111) μmol/L, P< 0.01)]. There were no significant difference in the levels of Cu and Zn between two groups (P> 0.05). Condusion Micreelements may play important roles in pathogenesis and development of PD, especially Fe and Mn.

Objective To study the protective effect of warming kidney and subsiding yang traditional Chinese medicine (TCM) method on lung tissues of rats with acute respiratory distress syndrome (ARDS) associated with sepsis. Methods Eighty healthy male Wistar rats were divided into normal control group, model group and low, medium and high dose Fusuheji groups by random number table, 16 rats in each group. The acute lung injury (ALI) model was established by injecting lipopolysaccharide (LPS) 3 mg/kg into a rat caudal vein within 5 minutes, and the normal control group was given the same volume of normal saline. Then the low, medium and high dose TCM groups were given low, medium and high dose Fusuheji TCM mixture (the ingredients of the mixture: radix aconite lateralis preparata 30 g, oysters 30 g, ginger 15 g, ephedra 15 g, licorice 10 g) 2.625, 7.875, 10.500 g/kg intragastric administration respectively. Equal volume of saline was given to the normal control group and model group by gavage. At 24 and 48 hours after respective administration, 8 rats were taken from each group to observe the pathological changes of lung tissues and score the lung injury. The rates of survival of rats were calculated after the experiment in various groups. Results After administration for 48 hours, the survival rate of rats in model group was obviously lower than that of the normal control group [18.7% (3/16) vs. 100.0% (16/16)], the low, middle and high dose Fusuheji groups' survival rates were all significantly higher than the rate of ALI model group [50.0% (8/16), 75.0% (12/16), 93.7%(15/16) vs. 18.7% (3/16), all P < 0.05]. There were no pathological changes in the lung tissues of rats in the normal control group, large amounts of exudates and hemorrhages were present in the lung tissues of ALI model group, and the inflammatory, exudative and hemorrhagic changes of lung tissues in the high, middle and low dose Fusuheji groups were obviously improved. After administration for 24 hours and 48 hours, the lung injury scores in the ALI model group were higher than those in control group (after administration for 24 hours: 7.83±0.60 vs. 2.89±4.23; after administration for 48 hours: 7.33±0.88 vs. 3.00±0.28), the scores of lung injury of any Fusuheji drug group were significantly lower than those of ALI model group, and the degrees of decrease were more marked in high dose Fusuheji group than those in low and middle dose Fusuheji groups (after administration for 24 hours: 3.37±0.32 vs. 6.00±0.44, 4.63±0.50; after administration for 48 hours: 3.25±0.25 vs. 5.25±0.25, 3.50±0.50). Conclusion The warming kidney and subsiding yang TCM method can improve the lung tissue injury in ARDS associated with sepsis in rats, promote the damaged lung tissue to recover, and ultimately the prognosis of ARDS rats is getting better.

In recent years, with the development of bone marrow and organ transplantation, cytomegalovirus (CMV) has become a common pathogen threatening patients having undergone organ transplantation. CMV may cause severe pulmonary infection and respiratory failure, leading to the death of patient with CMV pneumonia. CMV infectious pneumonia is characterized by the formation of huge type A eosinophil inclusion bodies in the nucleus and cytoplasm of the infected cells. The susceptible population is often associated with low immune function, and to promote the recovery of autoimmune function is the key point for treatment of CMV pneumonia, and the plasma exchange therapy can reconstruct the autoimmune function and improve the prognosis of patients with CMV pneumonia to a certain extent. Now the experience of 1 patient of severe CMV pneumonia treated by ECMO combined with plasmapheresis is reported.
