ObjectiveTo study the occurrence and influence factors of drug-induced injuries of vital organs caused by traditional Chinese medicine injection.MethodsChina Hospital Knowledge Database (CHKD) from 1993-2013 and case reports concerning adverse effects and drug-induced diseases caused by traditional Chinese medicine injection from Wanfang Data Knowledge Service Platformwere retrieved. Indicator systemwasestablished and relevant contentsweresummarized and analyzed.Results34 types of traditional Chinese medicine injectionswereincluded and 699 drug-induced diseasesweresummarized, taking up 53.98% of the total adverse effects. Among them, the top three included in the drug-induced diseaseswere acanthopanax injection, safflower injection and Mailuoning injection. The non-conformance between the traditional Chinese medicine injections in the literature and instructions mainly reflects unreasonable solvent selection, large compatibility concentration and usage and dosage beyond those specified in the instructions. ConclusionThe occurrence of drug-induced injuries of vital organs caused by traditional Chinese medicine injectionis relatively high, drug instructions shall be strictly followed in accordance with requirements during clinical application.

ObjectiveTo evaluate the value of transcranial Doppler (TCD) in pecutaneous transtuminl angioplasty and stenting (PTAS).MethodsThe index of hemodynamics, include mean peak flow velocity (Vm), systolic peak flow velocity (Vs), enddiastolic peak flow velocity (Vd), pulsatility index (Pi), resistance index (Ri) in 47 cases with the stenosis of the middle cerebral artery were investigated, while compared with that of intra arterial digital subtraction angiography (DSA). ResultsVs and Vm of 41 cases increased while the Pi reduced after operation, Ri had no change; Vs, Vm, Vd increased and Pi reduced with no reflow signal in 5 cases. Vs and Vm increased with Vd reduced in only 1 case. The accuracy rate with DSA in moderate or severe stenosis was 75% or 83% respectively. ConclusionTCD, as it's reliable, no-invasive, convenience and cheap, can play an important role in assessing the effect of PTAS in middle cerebral artery stenosis.

Background:Tryptophan(TRP)is an essential amino acid,and can produce 5-hydroxytryptamine(5-HT)via 5-HT signal pathway and kynurenine( KYN)metabolic pathway under the catalysis of enzyme,thereby participating in the pathogenesis of visceral hypersensitivity in diarrhea-predominant irritable bowel syndrome(IBS-D). Aims:To investigate the relationship between visceral sensitivity and TRP metabolic pathway in patients with IBS-D. Methods:Thirty patients with IBS-D and 30 healthy controls from June 2012 to January 2014 at Guangdong Provincial TCM Hospital were enrolled. Score of gastrointestinal symptom rating scale( GSRS)was evaluated. Visceral sensitivity was measured by anorectal manometry. RT-PCR and Western blotting were used to detect mRNA and protein expressions of colon mucosal IDo, respectively. Serum 5-HT,5-HIAA,TRP,IDo,KYN,KYNA concentrations and IDo activity,KAT activity were determined by high performance liquid chromatography assay. Results:Compared with control group,GSRS score was significantly increased(P < 0. 05),initial perception threshold,defecation threshold,pain threshold were significantly decreased(P < 0. 05),anorectal constriction pressure was significantly increased( P < 0. 05),serum 5-HT,5-HIAA concentrations were significantly increased(P < 0. 05),mRNA and protein expressions of IDo were significantly increased (P < 0. 05),serum KYN was significantly increased(P < 0. 05),KYNA was significantly decreased(P < 0. 01),IDo activity was significantly incseased(P < 0. 01),and KAT activity was significantly decreased in IBS-D group(P < 0. 01). Correlation analysis showed that initial perception threshold,defecation threshold,pain threshold and anorectal constriction pressure were correlated with 5-HT,5-HIAA,TRP,KYN,KYNA,IDo activity and KAT activity in patients with IBS-D (P < 0. 05). Conclusions:TRP metabolic pathway is correlated with visceral hypersensitivity in patients with IBS-D.

OBJECTIVETo study the molecular mechanism of Yangjing Zhongyu Decoction (YZD) n-butanol extracts (ZDC) and ethyl acetate extracts (YSYZ) in reducing androgen in porcine granulose cells by mitogen-activated protein kinase (MAPK) pathway.

METHODSPorcine granulose cells were isolated and cultured. They were inoculated by MAPK inhibitor PD98059 at different concentrations, and then they were divided into the blank control group (0), 1, 3, 10, and 25 micromol/L groups. After 24-h culture the cytochrome P450c17a (CYP17) mRNA expression level was detected using Real-time fluorescent quantitative PCR. Contents of androgen (testosterone) in the supernate were detected using RIA and optimal PD98059 concentration screened. After intervened by 10 micromol/L PD98059 for 24 h, the culture solution was intervened by effective ingredients of with or without YZD or YSYZ at various concentrations (0, 1 , 5, 25, 50 mg/mL) at various time points (3, 6, 18, 24 h). Expression levels of p-ERK1/2, c-Fos and CYP17 were detected by Western blot. Testosterone content in the supernate was determined by radioimmunoassay (RIA).

RESULTSTen pLmol/L PD98059 could obviously decrease p-ERK1/2 protein expression and increase CYP17 mRMA expression, and elevate testosterone content in the supernate (P < 0.05). ZDC and YSYZ at 25 ng/mL could increase p-ERK1/2 protein expression and c-Fos levels, and reduce CYP17 protein expression, and lower testosterone content in the supernate after 6-h intervention (P < 0.01).

CONCLUSIONEffective ingredients of YZD could reduce androgen production in porcine granulose cells through increasing activities of MAPK.

Objective To evaluate the clinical application value of modified CURB-65 score for assessing severity of community-acquired pneumonia (CAP) in emergency patients.Methods During the period from May 2011 to May 2012,198 emergency patients with CAP enrolled in this study were evaluated by CURB-65 score and modified CURB-65 score,respectively.Based on the severity of CAP,patients were divided into mild pneumonia group (Group A,n =107) and severe pneumonia group (Group B,n =91).The clinical status and biomarkers (the white blood cell count,procalcitonin,pneumonia severity index,hospitalization days,and hospitalization expenses) were recorded and compared with t test.Group B was divided into survived-subgroup (n =62) and death-subgroup (n =29).The differences in CURB-65 score and modified CURB-65 scere between the two groups were compared with t test.The correlation of CURB-65 score and modified CURB-65 score with procalcitonin,pneumonia severity index,hospitalization days,and hospitalization expenses were determined with Pearson rank correlation method.Results The procalcitonin,pneumonia severity index,hospitalization days,hospitalization expenses,modified CURB-65 score and CURB-65 score in Group B were significantly higher than those in Group A [(3.70 ± 0.83) vs.(1.27±0.24),t=28.91,P＜0.01; (121.33±16.74) vs.(73.79±9.21),t=25.23,P＜0.01;(25.79±10.13) vs.(14.85 ±6.83),t=9.02,P＜0.01; (22.71 ±3.84) vs.(9.83 ±1.24),t=32.76,P＜0.01; (3.69±1.03) vs.(3.32±1.06),t=2.48,P＜0.05; (4.21±1.13) vs.(3.41±0.96),t =5.39,P＜0.01],while no significant difference was observed in the white blood cell count between GroupA and B (17.58 ±5.99 vs.16.86±4.41,t =0.97,P＞0.05).For Group B,the modified CURB-65 score of death-subgroup was significantly higher than that of survived-subgroup [(4.75± ± 1.17) vs.(4.01 ± 1.09),t =2.95,P ＜ 0.01],whilc no significant difference was observed in the CURB-65 score between the death-subgroup and survived-subgroup (4.01 ± 1.15 vs.3.58 ±0.97,t =1.86,P ＞ 0.05).The CURB-65 score positive correlated with the procalcitonin (r =-0.803,P =0.025),and had no obvious correlation with the pneumonia severity index,hospitalization days,and hospitalization expenses (r=0.621,P=0.320; r=0.701,P=0.231; r=0.675,P=0.256); The modified CURB-65 score significantly positively correlated with the procalcitonin,pneumonia severity index,hospitalization days,and hospitalization expenses (r =0.951,P =0.003 ; r =0.965,P =0.002 ; r =0.947,P =0.004 ; r =0.961,P =0.002).Conclusions Compared with the CURB-65 score,the modified CURB-65 score is more efficient in evaluating the severity and prognoses of CAP for emergency patients.

Objective To investigate the effects of Shenfu injection ( SF,a Chinese herbal medicine preparation made of Codonopsis pilosula and Aconitum carmichaeli) on the cell apoptosis of focal cerebral ischemic-reperfusion injured rats and the expression of heme oxygenase-1 (HO-1). Methods Forty-two male Sprague-Dawley rats used for producing unilateral brain ischemia reperfusion model were randomly divided into three groups:sham operation group ( Sham group),ischemia reperfusion group ( IR group),and SF Injection group (SF group).The model of focal cerebral ischemia-reperfusion injury was induced by transient occlusion of middle cerebral artery (ischemia for 2 h,and reperfusion for 3,6 h respectively).In SF group,SF ( 10 mg/kg) was intraperitoneally injected duri(n)g reperfusion.Cell apoptosis rate in brain tissue was detected by the technique of Annexin-V-PI double staining and was counted in flow cytometer.Expression of HO-1 in brain was measured by RT-PCR,while the pathological and ultra structure changes of cerebral tissue were also observed.Results Cell apoptosis rate of brain tissue were significantly higher in IR group than that in Sham group (P ＜0.01 ),while SF group had less significant changes in cell apoptosis rate, HO-1 level of brain tissue than IR group (P ＜ O.01 ).The ultra structure change of brain tissue was less in SF group than that in IR group.Conclusions During early stage of brain IR injury,SF inhibits cellular apoptosis and in turn protects the brain from injury which is attributed to the increase in HO-1 expression induced by SF.
