Effect of Taizhi??an capsule combined with Simvastatin on hyperlipidemia in diabetic patients

Objective: To evaluate the effectiveness and safety of Taizhi’an (TZA) capsule combined with Simvastatin (Sim) in treating hyperlipidemia in diabetes mellitus (DM) patients.Methods: Eighty cases of type 2 DM patients with hyperlipidemia were randomized into two groups, 40 in each group. The patients in the treated group took orally TZA capsules at the dose of 0.9 g 3 times a day and Sim 10 mg at bedtime. And the patients in the control group were treated with Sim 20 mg alone at bedtime. Both regimens lasted for 12 weeks. Before and after the study the changes of blood lipid levels and adverse reaction were investigated.Results: The serum levels of total cholesterol (TC), triglycerides (TG) and low density lipoprotein-cholesterol (LDL-C) were decreased respectively by 28.8%, 18.2% and 26.3% in the treated group; and by 29.4%, 19.4% and 24.6% in the control group. On the contrary, high density lipoprotein-cholesterol (HDL-C) was increased by 23.5% in the treated group and by 29.4% in the control group. All these changes were statistically significant before and after treatment (allP<0.05), but they did not differ statistically between the two groups (P>0.05). There was no significant changes in hemoglobin A1c (HbA₁c). Patients in the treated group did not develop any adverse reactions. However, ALT was found to be higher above the normal range in 5% of the patients in the control group.Conclusion: In treating hyperlipidemia in DM patients, combination of TZA with Sim 10 mg taken daily achieved satisfactory efficacy which was similar to Sim 20 mg daily alone. But the combination therapy conducted in the treated group proved to be better in safety, and could overcome adverse reactions resulting from Sim that was seen in the control group.     

Radioenhancing effect of earthworm capsule medication on radiotherapy in the treatment of patients with carcinoma of esophagus or lung

Earthworm capsule is an extract from earthworm made in our laboratory.From1986 to 1989,486 patients with carcinoma of esophagus or lung were randomly divided into 2groups,one group received radiotherapy alone(control group)and the other radiotherapycombined with earthworm capsules(treatment group).All cases were diagnosedpathologically or cytologically.In a two-month treatment course,earthworm capsuleswere given orally twice a day,2～3 capsules each time,each capsule containing 60 mg ofthe extract.Compared with the control group,the CR(complete remission)rate andCR+PR(partial remission)rate in patients with carcinoma of esophagus treated byradiotherapy in combination with earthworm capsule increased 9.7%(P<0.01) and 9.6%(P<0.05),while in patients with carcinoma of lung,they increased 10.6%(P<0.05)and13.5%(P<0.05),respectively.The earthworm capsule caused irritation in the alimentarytract,the patients displaying slight nausea and vomiting(16.7% in thecombination treatment group and 10.0% in the control group).However,these side ef-fects could be alleviated when capsules were taken after meal or with honey concomitantly.No deleterious effects on the heart,liver,kidney,skin,hematopoietic or nervous systemwere seen.

The effect of Nifedipine on the expression of type I collagen in gingival fibroblasts

Objective:To investigate the effect of nifedipine(calciumchannel blocker)on the expression of collagen in gingival fibroblasts invitro.Methods:Primarily gingival fibroblasts were cultured and incubated with various concentrations of nifedipine(108μg/L,360μg/L and 1200μg/L)for 5 days.Gingival fibroblasts were primarily cultured derived from nifedipine responders and non-responders in the presence of 360μg/L nifedipine.Enzyme-linked immunosorbent assay was used to evaluate the amount of type I collagen.Cell proliferation was measured by cell counting with evaluating MTT value.Results:The expressions of collagen and cell proliferation were significantly different among the high concentration groups and the others on the fifth day,especially higher in 360μg/L and 1200μg/L groups and also different among nifedipine responders and non-responders.Conclusion:The expression of collagen and cell proliferation may be concerned with the biological mechanism for gingival overgrowth.     

The beneficial effects of qigong (气功) on the ventricular function and microcirculation of deficiency in heart-energy hypertensive patients

Ultrasonic cardiograms were performed on 120 aged subjects. Experiments showed the left ventricular function in the hypertensive aged group (80 cases) was lower than that in the aged normal blood pressure group (40 cases), while the left ventricular function in the deficiency of Heart-energy hypertensive patients (46 cases) was lower than in the non-deficiency of Heart-energy hypertensive patients (34 cases). After practising Qigong for 1 year, cardiac output was increased. The total peripheral resistance decreased and the ejection fraction mitral valve diastolic closing velocity and the mean velocity of circumferential fiber shortening tended to be increased. The results indicate Qigong has a regulatory effect on haemodynamic alteration, as well as on improvement of the left ventricular function. Nailfold microcirculation detection of 120 aged subjects was made. The results showed that hypertension had an accelerating effect on the disturbance of microcirculation. The incidence of disturbance of microcirculation was 73.91% in the deficiency of Heart-energy hypertensive patients, after 1 year of Qigong practice, the incidence of disturbance of microcirculation was 39.13% (P<0.01). The results suggest Qigong has an effect on Heart-energy and regulation of the blood channel.     

The postsynaptic effect of taxol on rat neuromuscular junction

Taxol was used as a tool reagent and the function of the microtubules (MTs) beneath thepostsynaptic membrane was studied in an isolated non-uniformly stretched muscle preparation of ratdiaphragm.After exposure to taxol (20 μmol/L,10min),the amplitude of acetylcholine potential ofinnervated muscle endplate was decreased by 30%,but the lime course of AChP and membrane po-tential remained unchanged.The results indicate that taxol can inhibit the responsiveness ofpostsynapfic membrane.It is therefore suggested that the site of action of taxol indudng inhibitionof postsynapfic responsiveness in neuromuscular junction may be the microtubules beneath thepostsynapfic membrane.

The effect of reactive oxygen species of inducing apoptosis on the hepatocacinoma in the rabbits

Objective: To study the effect of reactive oxygen species of inducing apoptosis on the heptocacinoma tissues following ischemia and reperfusion and perfusion hyperoxia liquid of hepatocarcinoma. Methods: The hepatocarcinoma animal models ware established by implantation of VX2 tumor constitution mass into the left middle lobe of liver of rabbits. The animals were subjected to 60 min clamp-induced ischemia of hepatic artery distributing in the left middle lobe followed by reperfusion atlh, Id, 3d and 7 d, respectively, and perfusion hyperoxia liquid (partial pressure of oxygen, PO2＞80 kPa) at the same time with reperfusion beginning. The concentration of MDA and NO ware tested. Apoptotic changes in the hepatocarcinoma and normal hepatic tissues were observed by means of HE staining and terminal de-oxynucleotidyl transferase-mediated dUTP nick end-labeling (TUNED. Results: The concentration of MDA in normal hepatic tissues and hepatocarcinoma tissue increased followed ischemia and reperfusion especially for reperfusion 1 h (4. 61 ±0. 40, 3. 10±0. 23) and restored to normal level at reperfusion 7 d in normal hepatic tissues but still kept high concentration in the hepatocarcinoma tissue. Even though concentration of MDA in normal hepatic tissues is higher than that of before ischemia and reperfusion, no difference have been found after perfusion of hyperoxia liquid, and in the hepatocarcinoma tissue. the increasing of concentration of MDA was obvious after simply ischemia and reperfusion at reperfusion Id (4. 25 ± 0. 45). The concentration of NO in normal hepatic tissues increased for reperfusion 3 d and 7 d(18. 17± 0. 13, 17. 45±0. 23),while that of hepatocarcinoma tissue decreased at reperfusion 3 d(15. 95±043). After perfusion of hyperoxia liquid, the concentration of NO in normal hepatic tissues kept increasing and that decreased in the hepatocarcinoma tissues in all time point and reached the lowest level at reperfusion 1 d(14. 62±O. 45). The result demonstrated the changes of concentration of NO and MDA in the hepatocarcinoma tissues ware more obvious than that of normal hepatic tissues(P＜0. 01). Conclusion: Perfusion of hyperoxia liquid from hepatic portal vein can intensify ischemia and reperfusion injury but less so for normal hepatic tissues.

The effects of scorpion(Buthus martensi Karsch)venom on rat left ventricular function

In order to investigate the cardiovascular effects of the scorpion(Buthus martensiKarsch)venom(BmKv),the left ventricle of the rats was catheterized via the right carotidartery.The LVP,LVEDP,+dp/dt max,Vmax,HR and BP were observed.The results showedthat intravenous injection of the BmKv(60μg/kg),in comparison with the control,elicited obvi-ous hypertension and increase of cardiac contractility,both of which lasted for 1h,while theheart rate had no significant change rand that pretreating the rats with alpha-adrenergic blocker,phentolamine,antagonized the hypertensive effects,but did not antagonize the increase of cardiaccontractility.Pretreatment with beta-adrenergic blocker,propranolol,has no influence on the ef-fects of the venom.It is suggested that the hypertensive effects are due to the activation of al-pha-adrenergic receptor,whereas the increase of cardiac contractility may not be resulted fromthe activation of beta-adrenergic receptor.The BmKv treated with dithiothreitol before injectionhad no cardiovascular effects,indicating that the intact disulfide bridges play a decisive role inthe cardiovascular effects of the BmKv.

The role of capsule endoscopy combined with double-balloon enteroscopy in diagnosis of small bowel diseases

Background The diagnosis of small bowel diseases remains relatively inefficient using traditional imaging techniques. Capsule endoscopy （CE） and double-balloon enteroscopy （DBE） are two novel methods of enteroscopy for examining the entire small bowel. The aim of this study was to evaluate the detection rate and diagnostic accuracy of CE and DBE in patients with suspected small bowel diseases and to investigate the clinical significance of combined use of these two novel modalities. Methods Two hundred and eighteen patients were evaluated for suspected small bowel disease, including 116 with obscure gastrointestinal bleeding and 102 with obscure abdominal pain or chronic diarrhea. One hundred and sixty-five out of these patients underwent CE first and 53 patients underwent DBE （under anesthesia with propofol） first. DBE was recommended after negative or equivocal evaluation on CE and vise versa. Introduction of the endoscope during DBE was either orally or anally and the patients were referred for a second procedure using the opposite route several days later when no abnormalities were found on the first procedure. The detection rates, diagnostic accuracy, tolerance and frequency of adverse events of these two modalities were then analyzed. Results Failure of the procedure was seen in one patient with CE and in two patients with DBE. Sixty-four DBE procedures were carded out in 51 patients; by the oral route in 34 cases, the anal route in 4 and both routes in 13 cases. The overall detection rate of small bowel diseases using CE （72.0%, 118/164） was superior to that with DBE （41.2%, 21/51）; X2=16.1218, P〈0.0001. The diagnostic rate （51.8%, 85/164） was also higher than that with the latter procedure （39.2%, 20/51）, but was not significantly different （X^2=2.4771, P〉0.05）. Furthermore, the detection rate of small bowel diseases in patients with obscure gastrointestinal bleeding using CE （88.0%, 88/100） was superior to that of DBE （60.0%, 9/15）; X2=7.7457, P=0.0054. Lesions were detected by DBE in 1 out of 4 patients in whom CE had a negative result. Suspected findings by CE were confirmed by DBE combined with biopsy in 12 out of 15 patients. On the other hand, small bowel lesions were identified by CE in all 3 patients after negative evaluations by DBE. There were no severe complications during or after either of the two procedures. Conclusions The detection rate of small bowel diseases by CE is very high. CE should be selected for the initial diagnosis in patients with suspected small bowel diseases, especially in patients with obscure gastrointestinal bleeding. DBE appears to be inferior to CE in the diagnosis of small bowel diseases. However, it was shown that abnormalities could still be identified by DBE in patients with normal images or used to confirm suspected findings from CE. DBE can also serve as a good complementary approach after an initial diagnostic imaging using CE.     

The effect of anastrozole on mRNA expression of oestrogen related gene in MCF-7 breast cancer cells

Objective： To look for additional markers of molecular biology response to anastrozole, a new aromatase inhibitor, on the growth and mRNA expression level of MCF-7 cell. Methods： We investigated the effect of anastrzole on growth and gene expression in the human breast cancer cell line MCF-7 and compared with the most widely used antiestrogen tamoxifen. We chose 4 genes to examine regulation of gene expression of estrogen regulated genes ： PR A, PR B, ErbB-2 and cyclin D1. Results： Compared with the tamoxifen, a statistically significant growth inhibition was observed with anastrozole. The PR A, PR B and cyclin D1 mRNA level in anastrozole treated cells was sigificantly below the level in tamoxifen treated cells （P〈0. 05）. They had agonistic effect on ErbB gene （P〉0. 05）. Conclusion： The third generation of aromatase inhibitors anastrozole exert more inhibit function in some expression of estrogen regulated genes than tomoxifen in MCF-7 cell line.
