Objective To observe the antitumor action of Wei Yi Ting granules (WYTG) and to explore its possible mechanism.Methods The inhibitory effect of WYTG and its different WYTG ingredient combinations on the growth of S180 tumor in mice was observed.Meanwhile,the effect of WYTG and its different ingredient combinations on the expression of P53 and PCAN during tumor development was studied by immunohistochemical method.Results WYTG had an obvious inhibitory effect on tumor growth and could reduce the positive cell number of P53 and PCAN,the difference being significant as compared with the blank control group(P 0.05).Conclusion WYTG,which has the actions of strengthening Qi,activating blood and removing toxicity,exerts an obvious inhibitory effect on tumor as compared with its ingredient combination of strengthening Qi and with that of strengthening Qi and removing toxicity.Its therapeutic mechanism may be related to the inhibition of the expression of P53 and PCAN and the influence on tumor-associated gene during the growth of tumor.

NO-1886 increases LPL mRNA and LPL activity in adipose tiss ue, myocardium and skeletal muscle, resulting in an elevation of postheparin pl asma LPL activity and LPL mass in rats. NO-1886 also decreasess plasma TG con centration and causes a concomitant rise in plasma HDL-C, reduces plasma gluco se, improves insulin resistance and ?-cell dysfunction. Therefore, the LPL act ivator NO-1886 or other possible LPL activating agents are potentially benefici al for the treatment of hypertriglyceridemia, hypo-HDL cholesterolemia, and pro tection from atheroscleroosis and diabetes.

Background and purpose:Brucine is one of the active components from Strychnos nux vomica,with signifi cant analgesic,anti-inflammatory and platelet-aggregating inhibitory properties.Due to its cytotoxic effect,the anti-tumor effect of brucine has increasingly been appreciated.In this study,we investigated the impact of brucine on A549 cells proliferation,apoptosis as well as the underlying mechanisms.Methods:MTT assay was used to examine the cell viability,flow cytometric analysis and fluorescent microscope were applied to examine cell apoptosis,ELISA method was used to examine the effect of brucine on PGE2 release from A549 cells and RT-PCR analysis was used to measure mRNA content,western blotting analysis was used to measure protein expression and luciferase activity was detected to examine the effect of brucine on COX-2 promoter activity.Results:Brucine was able to suppress the proliferation of A549 cells and induce cell apoptosis to time-dependent and dose-dependent manner.To understand the mechanisms,COX-2 was identifi ed to be an important target molecule involved in the apoptosis induced by brucine because brucine could suppress the COX-2 mRNA,protein expressions as well as PGE2 release in A549 cells in a timedependent manner.Furthermore,overexpression of COX-2 abrogated brucine-induced cell apoptosis,in contrast,when A549 cells were transfected with COX-2 siRNA,the apoptotic effect of brucine was dramatically enhanced.Further analysis revealed that brucine was able to suppress COX-2 transcriptional activation.Conclusion:Brucine was able to induce lung cancer apoptosis via downregulation of COX-2.

Objective To explore and compare the effect of sevoflurane and disoprofol to inflammatory factors in patients received abdominal surgeries.Methods Patients with sevoflurane and disoprofol respectively were anaesthetized and detected IL-6,IL-8,IL-10 and TNF-α in their serum at T1 (when anesthesia induction),T2 (after anesthesia induction),T3 (30min after beginning of operations) and T4 (after operations).Results Compared with T1,the serum level of IL-6,IL-8,IL-10 and TNF-α increased significantly in all patients(all P ＜ 0.05) ; Compared with disoprofol group,the serum level of IL-6,IL-8 and TNF-α increased significantly (all P ＜ 0.05) ; Compared with sevoflurane group,the serum level of IL-10 increased significantly(all P ＜ 0.05).Conclusion Intravenous anesthesia with disoprofol in patients receiving abdominal operations is proper for maintenance of inflammatory balance.

Objective To explore the effect of prospective nursing on preventing constipation for patients with acute myocardial infarction(AMI). Methods 43 AMI patients during July 2008 and June 2010 in our hospital were classified as the observation group, besides the nursing routine of the acute myocardial infarction plus routine therapy to prevent constipation, prospective nursing was implemented.Through the retrospective analysis of medical record, 41 of AMI in our hospital during March 2006 and June 2008 were classified as the control group, they were given the nursing routine of the acute myocardial infarction plus routine therapy to prevent constipation and the nursing intervention after occurrence of constipation. The defecation condition was assessed for the two groups of patients on admission and the defecation and mortality rate was compared on the eighth day of hospitalization. Results There was significant difference in constipation and mortality rate between the two groups of patients during hospitalization. Conclusions The prospective nursing for AMI patients to prevent constipation can obviously reduce the incidence of constipation, thus to avoid serious complications caused by constipation and reduce mortality.

Based on the professional characteristics of obstetrics and gynecology department,teaching reform should take clinical manifestations of diseases as the main direction of clinical probationary teaching,stress the formation cultivation of medical students' clinical logic,add human-oriented thought into clinical teaching and stress medical ethics education,and construct a novel teaching mode in the clinical probationary practice in department of obstetrics and gynecology so as to improve clinical teaching of obstetrics and gynecology.

This study was conducted to assess the effects of over ten years of antihyper-uricemic follow-up therapy on 65 patients out of 118 cases of primary gout. It was found that reduced tophaceous deposition correlated with normalization of the serum uric acid concentration. The patients with lower mean uric acid concentrations were more likely to have a reduction in tophi. There was a lack of correlation between mean serum uric acid concentrations and radiographic changes of gout. Although treatment allowed better control of the disease in general, serum uric acid concentration alone may not provide an effective means of monitoring the progression of the disease. In this series,antihyperuricemic agents were generally well tolerated. Gastrointestinal upset was seen in 13 of the 65 cases (20%),mild leukopenia in 6 patients. skin rash in 2 and herpes simplex in 1. No patient was withdrawn from the therapy owing to the untoward side effects.

Objective To develop an in vivo procedure f or His bundle pacing (HBP) and radio-frequency (RF) ablation of the atrio-ventricular node (AVN) guided by intracardiac echocardiography (ICE) and tissue Doppler imaging (TDI). The procedure included a custom designed bipolar active fixation pacing lead and steerable delivery catheter, and a commercial RF generator and ablation catheter. Methods Six anesthetized- closed-chest canines were tested. The anatomy in the His bundle and AVN regions, and the onset of myocardial electro-mechanical activation were identified using ICE and TDI. The lead and RF ablation catheter were navigated using an ICE catheter (for local detailed imaging) and fluoroscopy (for global imaging). Surface QRS morphologies were recorded to confirm HBP and third degree block post-ablation. Results Direct His bundle pacing was achieved in one canine, and His + ventricular septal pacing in the remaining five. QRS width in sinus rhythm and HBP were ( 59.7-? 5.3-)ms and ( 82.8-? 16.6-)ms separately (P= 0.02-). The increased QRS width for HBP was due to early septal activation. HBP thresholds were ( 3.0-? 1.0-) volts at 0.5 ms (N=5 due to a late exit block). The mean procedure durations were: HBP 40 minutes (3 to 81 minutes), AVN ablation 3 minutes (2 to 5 minutes), and total X-ray exposure 13 minutes (1 to 55 minutes). Post-mortem analysis of the lead and ablation lesions confirmed correct anatomic localization for HBP and AVN ablation. Conclusions ICE provides precise anatomic guidance of HBP lead implantation and AVN ablation and can significantly reduce exposure to fluoroscopy.

ObjectiveTo summarize the clinical characteristics of pt osis,one of complications after double eyelid blepharoplasty, and to explore i ts causes and attempt for the resolutions. MethodsThe clinica l symptoms were divided into three types based on the degrees of the ptosis afte r double eyelid blepharoplasty. The causations in 25 cases of different degree o f ptosis after double eyelid blepharoplasty were investigated and analyzed durin g operations. The local adhesive deformities were analyzed so as to take differe nt resolutions for the complication. Results It seemed that th e operative damage to the aponeurosis was the main reason for the complication. So it caused the scar adhesive deformities between the palpabralis aponeurosis a nd the orbital membrane or the skin of upper eyelid, resulting in the difficult y of the palpabralis muscle's contract and unablility of the muscle function in different degrees. Conclusion The ptosis can surely be av oided if we have good knowledge about the mechanism of double fold formation and the anatomy of eyelids and perform the operation meticulously.
