ObjectiveTo observe the effect of Tongxinfang on coronary collateral formation and stent-restenosis in patients with coronary artery disease after stenting.Methods61 patients with coronary artery disease were randomly divided into the treatment group (n=30), and control group (n=31). Patients of the treatment group were taking Chinese medicine Tongxinfang for six months, but cases of the control group only received basic treatment. Coronary collateral formation, stent-restenosis and ejection fraction (EF) of patients of two groups were assessed through aniograms and echocardiography before treatment and after six months.ResultsCoronary collateral formation and EF of patients of the treatment group improved significantly compared with cases of the control group (P<0.01 or P<0.05), but the minimal lumen diameter and percent of diamter stenosis were not significantly different between two groups (P>0.05).ConclusionTongxinfang can improve coronary collateral formation and EF.

ObjectiveTo observe the effect of Yiqihuoxue recipe on left ventricular remodeling after acute myocardial infarction (AMI).Methods40 patients with AMI were randomly divided into treatment group and control group with 20 cases in each group and received Yiqihuoxue recipe or fasinopril respectively for 6 months. Changes of clinical symptoms, the level of plasma angiotensin Ⅱ(ATⅡ), aldosterone (ALD), endothelin (ET) and echocardiographical indexes: left ventricular end-diastolic volume index (LVEDVI), left ventricular end-systolic volume index (LVESVI), ejection fraction (EF), left ventricular mass index (LvmassI), wall motion index (WMI), wall thick (WT), E/A were assessed before discharge, and in the end of 3rd and 6th month after AMI.ResultsClinical symptoms of patients of treatment group improved significantly (P<0.01). EF and E/A of all patients in two groups increased (P<0.01 or P<0.05), LvmassI and WT reduced (P<0.05), but there were no significantly differences between two groups in LVEDVI, LVESVI, EF, LvmassI, WMI, E/A and WT(P>0.05). The level of plasma ET decreased in treatment group (P<0.05), the level of plasma ATⅡ and ALD of control group decreased more than that of treatment group (P<0.05).ConclusionYiqihuoxue recipe can significantly improve clinical symptoms, cardic function, and left ventricular remodeling, showing a better clinical efficacy.

OBJECTIVETo observe the clinical effect of electric stimulation of long-term retaining needle on analgesia after laparoscopic cholecystectomy (LC) and the impacts on the post-surgical flatus time.

METHODSUnder static absorptive composite general anesthesia, 90 cases of LC were randomized into three groups, 30 cases in each one. In the control group, the analgesia was not applied after LC. In the analgesia-pumper group, the patient controlled intravenous analgesia (PCIA) was used. In the needle-retaining group, the electric acupuncture stimulator was used. The needles were inserted transversely at Riyue (GB 24), Qichong (ST 30) and Yanglingquan (GB 34) and fixed with sterile sticker. Separately, in 8 h and 24 h after surgery, the electric acupuncture stimulation with disperse-dense wave, 2 Hz/100 Hz frequency was applied continuously for 30 min. Visual analogue scale (VAS), adverse reactions such as vomiting and nausea and the postoperative flatus time in 2, 4, 8, 12, 24 and 36 h after surgery were observed and recorded in the three groups.

RESULTSIn 2, 4, 8, 12 and 24 h after surgery, VAS scores in the needle-retaining group and the analgesia-pumper group were all lower than those in the control group (P < 0.05, P < 0.01). The analgesia effect at the above time points in the needle-retaining group was better than that in the analgesia-pumper group (all P < 0.05). There was not adverse reaction in the needle-retaining group. But there were 3 cases of somnolence, 6 cases of nausea and 3 cases of vomiting in the analgesia-pumper group, and 2 cases of nausea and 1 case of vomiting in the control group. The flatus time was quite earlier in the needle-retaining group as compared with the other two groups [(14.77 +/- 4.99) h vs (18.50 +/- 4.22) h, P < 0.01; (14.77 +/- 4.99) h vs (18.17 +/- 4.69) h, P < 0.05].

CONCLUSIONThe electric stimulation of long-term retaining needle is safe and effective in analgesia after LC. It avoids the adverse reactions of analgesics and promotes postoperative flatus.

OBJECTIVETo study the impact of IFN-gamma on liver fibrosis and its possible mechanism. Thirty healthy male SD rats were randomly divided into two groups: fibrosis model group, IFN-gamma treatment group. Experimental liver fibrosis was induced by subcutaneous injection of CCl4. After 12-week-treatment, serum hyalurnic acid and TGF-beta1 was examined, histopathological changes and degrees of fibrosis were observed by optical microscopy. Meanwhile, the expression of TGF-beta1, TbetaR- I and Smad2/3 proteins was detected by immunohistochemistry and quantified by using computerized image analysis.

RESULTS(1) Pathological observation of hepatic specimens: histological examination showed that there were significant difference between normal group and fibrosis model group by comparing with the degrees of inflammation and fibrosis (P < 0.05). And the difference between fibrosis model group and IFN-gamma treatment group was significant (P < 0.05). (2) Changes of the hepatic fibrosis index (serum HA and TGF-beta1): the levels of serum HA, TGF-beta1 in fibrosis model group were higher than IFN-gamma treatment groups (P < 0.05). (3) Changes of gene protein levels about TGF-beta1/Smad: the expressions of TGF-beta1, TbetaR- I and Smad2/3 in rat hepatic tissue were detected with immunohistochemistry techniques. The expressions of the three items in model group were higher than normal group (P < 0.01). The difference between model group and IFN-gamma treatment group was significant (P < 0.05);

CONCLUSIONIFN-gamma treatment group had significant results on treating experimental hepatic fibrosis. By the way of inhibiting expressions of TGF-beta1, TbetaR- I, Smad2/3, IFN-gamma treatment group exerted its anti-fibrosis effect.

This study left flavonoids and alkaloids Chinese herbal monomer with common parent nucleus as cream base carriages drug respectively, cream base were prepared with stable span 60-tween 80 emulsification system. The near-infrared stability analysis technology was performed to quantitatively characterize the physical stability of cream. Base on the theory of gel network structure, theory of emulsification, theory of solubility parameter and theory of double layer, the influence mechanism of Chinese herbal monomer on physical stability of cream was discussed. The results showed that tetrahydropalmatine, matrine and naringenin had similar solubility parameter value with cream base material, creams prepared with those Chinese herbal monomer have higher Zeta potential value and stronger physical stability, and that those creams had similar microstructure information with cream base. However, a larger solubility parameter difference exists between baicalin, baicalein, berberine, palmatine and cream base material. Creams prepared with those Chinese herbal monomers had lower Zeta potential value and poorer physical stability, and that those creams had great different microstructure information with cream base.
