Objective To evaluate the effect of Danshen Chuanxiongqin injection combined with Xuesaitong capsule on blood viscosity in patients with pulmonary heart disease.Methods 80 patients with pulmonary heart disease who were admitted to our hospital between January 2013 and November 2015 were studied,the patients were randomly divided into the combined group and the control group according to the order of admission,40 cases in each group.Control groups were treated with Xuesaitong capsule,and the combined group were treated with Danshen Chuanxiongqin injection on the basis of the control group.The clinical efficacy,blood viscosity(whole blood viscosity,plasma viscosity,whole blood viscosity ratio),blood indexes(blood platelet aggregation rate,erythrocyte aggregation index,erythrocyte deformation index),cardiac function and safety were observed.Results There were no significant differences in blood rheological indexes,LVEF,MAP and HR between the two groups before treatment.After treatment,the whole blood viscosity,plasma viscosity,whole blood viscosity ratio,platelet aggregation rate,erythrocyte aggregation index,erythrocyte deformation index,MAP and HR in the two groups were significantly lower than those before treatment,while LVEF was significantly higher,and the changes in the combined group were more significant than those in the control group(P<0.05).After treatment,the clinical total effective rate of treatment in the combined group(88.89％)was significantly higher than that in the control group(62.50％).Conclusion Danshen Chuanxiongqin injection combined with Xuesaitong capsule is effective in the treatment of pulmonary heart disease.It can significantly reduce blood viscosity,blood related indexes and improve cardiac function.

OBJECTIVE: To observe the effects of herb therapy for benefiting qi and removing blood stasis on ultrastructure of vascular endothelial cells (VECs) and vascular smooth muscle cells (VSMCs) of uterine endometrium in rabbits with copper intrauterine device. METHODS: Fifty-six rabbits were randomly divided into seven groups, which were normal control group, sham-operation group, untreated group, indomethacin-treated group and low-, medium- and high-dose Gonghuan Zhixueling Recipe (GHZXLR)-treated groups. The rabbits in the last five groups were operated with copper IUD insertion and then orally given distilled water, indomethacin and low-, medium- and high-dose GHZXLR respectively for at least one week. Rabbits in the normal control group and sham-operation group were given distilled water orally. The ultrastructure of VECs and VSMCs of uterine endometrium in rabbits was observed by transmission electron microscopy. RESULTS: The morphological changes of VSMCs revealed intracellular edema, organelle disintegration and decrease of organelle amount, or cell atrophy and vacuolar degeneration of mitochondria in the untreated group, and the amount of collagen fibers also increased outside the VSMCs. Local interstitial edema in subendothelial substance and vacuolar degeneration of mitochondria in VECs were both observed. The ultrastructural damages to the mitochondria, Golgi bodies and myofilament of VECs and VSMCs and the intercellular substance in GHZXLR-treated groups were slighter than those in the untreated group, while these damages had no significant differences as compared with those in the indomethacin-treated group. CONCLUSION: The Chinese herb therapy for benefiting qi for removing blood stasis has the protective effect on VECs of uterine endometrium in the rabbits with copper intrauterine device. It appears to be a good treatment for menorrhagia induced by copper IUD insertion.

OBJECTIVE: To explore the hemostatic and analgesic effect of Gonghuan Zhixue Tablet (GHZXT) on mice and to produce experimental evidence for exploiting new drug for endometrorrhagia caused by Cu-intrauterine contraceptive device (Cu-IUD). METHODS: Compared with 6-aminocaproic acid and notoginseng, the effects of GHZXT on clotting and bleeding time of mice with capillary method and severed tail were investigated; and compared with aspirin, the analgesic effects of GHZXT on mice were investigated with hot plate and torsive body method. RESULTS: The clotting time of mice was remarkably shortened with a rising of the dosage of GHZXT and the difference between each therapeutic group and distilled water group was remarkable. As compared with distilled water group, the bleeding time of each dosage group of GHZXT was obviously shortened; and each dosage of GHZXT could prolong the time of pain reaction to hot plate and decrease the degree of torsive body of the mice. CONCLUSION: Pharmacological experiment has proved that GHZXT has evident hemostatic and analgesic function.

Objective To observe the electrocardiogram changes of threatened crowds in Keshan disease (KSD) endemic area in Shandong province. Methods In 2008,inhabitants from 21 villages of Zoucheng,Sishui,Tengzhou, Yishui, Pingyi, Wulian, Juxian and Qingzhou regions were selected as subjects undergoing electrocardiogram. No less than 100 people were chosen from each village and the examination rate was not lower than 85%. Results Among the 3378 inhabitants investigated,460 cases showed abnormal electrocardiogram and the total incidence of abnormal electrocardiogram was 13.62% (460/3378). The relatively high incidence was T-wave changes,QRS low voltage and ST-T changes,the detection rate being respectively 2.69% (91/3378), 1.92% (65/3378) and 1.72% (41/3378). The highest incidence of abnormal electrocardiogram (26.76%,55/213),the intermediate(21.50%,43/200) and the lowest(5.50%,12/218) was respectively found in Pingyi,Qingzhou and Sishui. Conclusions The threatened crowds in KSD endemic area in Shandong province are still in a state of high abnormal electrocardiogram detection,and electrocardiogram is of great value in the evaluation of KSD patients.

ObjectiveToinvestigatetheinflammatoryresponseandapoptosisof peripheral blood mononuclear cells(PBMCs) and their regulation by triptolide(TP) in IgA nephropathy(IgAN) patients.MethodsBlood samples were collected from 29 IgAN patients and 16 healthy individuals.TNF-α and IL-6 concentrations were measured by ELISA and NO concentration by Griess reagent in the plasma of samples.PBMCs were isolated from IgAN patients and cultured in vitro,and subsequently activated by PHA(10 mg/L).The cytotoxicity of different TP concentrations was assayed by MTT and two non-toxic concentrations (12.5 μg/L or 25.0 μg/L)were selected for treatment.TNF-α,IL-6 and NO concentrations were measured in the culture media collected from PBMCs cultures activated by PHA (10 mg/L) and treated with TP (12.5 μg/L or 25.0 μg/L).The PHA-activated,TP-treated cells apoptotic rate was analyzed by FACS using Annexin V-FITC staining.The expression of Bcl-2,Bax,caspase-9 and caspase-3 were detected by RT-PCR and Western blotting from lyses of PHA-activated with or without TP-treated cells.ResultsThe serum concentrations of TNF-α[(131.57±50.61) ng/L vs(30.24±18.93) ng/L,P＜0.01],IL-6[(76.36±25.21) ng/L vs(35.08±16.59) ng/L,P＜0.01] and NO[(46.36±12.93) μmol/Lvs (26.61 ±10.87) μmol/L,P＜0.01] were significantly increased in IgAN patients compared to healthy individuals.PBMCs viability in culture decreased after TP treatment in a dose-dependent manner.TP also inhibited TNF-α,IL-6 and NO levels in the media of PHA-activated PBMCs in culture and induced PBMCs apoptosis.The expression of Bcl-2 decreased markedly and Bax,caspase-9 and caspase-3 increased significantly after TP treatment (all P＜0.05).Conclusions The PBMCs from IgAN patients are in a highly activated state,and have a high apoptotic rate.TP treatment induces benificial effects in IgAN patients by inhibiting the activation of PBMCs by activating pro-apoptotic pathway.

Saliva and blood were collected from two patients who had not received post exposure prophylaxis in the cities of Wenzhou and Xinning respectively. Both patients were confirmed as positive for rabies by detection of rabies virus specific nucleoprotein antibodies in the sera by Western Blot. However, rabies virus specific RNA was only identified in the saliva collected from the patient in Wenzhou. Furthermore, the isolate Zhejiang Wz0 (H) was obtained by inoculating one-day-old suckling mice. Both nucleoprotein (N) and glycoprotein (G) genes from the isolate were amplified by RT-PCR and sequenced. Phylogenetic analysis indicated that the isolate belonged to classic rabies virus, and shared a higher homology with the street viruses from dogs in the main endemic areas in China and the street virus from dogs in Indonesia than with other known strains. Further comparison of the deduced amino acid sequences between the isolate and the vaccine strains used in China showed that the virus had a higher level of homology with the vaccine strain CTN than with the other vaccine strains (3aG, PV, PM and ERA). In particular, amino acid residues substitutions located in antigenic site Ⅲ in the G protein, which could react with the neutralizing antibodies, were observed. These results suggested that the virus belonged to the classic rabies virus, and both N and G genes diverged from the current vaccine strains used in China at either the nucleotide or the amino acid level.
