Objective To compare knowledge about hypertension between elderly Chinese urban patients with preferences for either traditional Chinese medicine (TCM) or Western medicine (WM).Methods Elderly (≥ 65 years old) patients with hypertension who prefer TCM treatment (n=112) or WM (n=126) were questioned about hypertension.Their answers were compared.Results Only 32.6% of participants correctly identified hypertension as a main risk factor of coronary heart disease and stroke,22.3% of patients answered that the main purpose of hypertension control was preventing cardiovascular disease.Other major reasons for these patients to seek medical treatment for their hypertension included:persuasion by physicians or their family members (21.6%),alleviating symptoms such as headache and dizziness (16.8%),lowering blood pressure without knowing specific reason (12.4%).The predictors for poor knowledge of hypertension were similar irrespective of preference for WM or TCM treatment,and included those with lower levels of education and older age.Television and newspaper (46.8%) were the most frequent sources of hypertension information for both groups.Among those who preferred TCM treatment,TCM has fewer side effects than WM and TCM cures disease while WM only alleviates symptoms were common beliefs held.Conclusion This study shows that knowledge of hypertension is similar among Chinese urban patients with preferences for either WM or TCM treatment and that misunderstandings about hypertension are common among the elderly patients.In order to control hypertension effectively,public health education is necessary.This should target those with a lower level of education and older age.

Objective To know the environmental lead pollution status of rural areas around the mining area in Guangxi,2008.Methods From August to December,2008,the survey was carried out in 28 villages of 4 counties,which were located in basin of three rivers and their tributaries.Six lead-zinc-tin mines were situated in the investigated area.The local samples were collected,including 101 rice samples,30 paddy samples,59 vegetable samples and 45 samples of meat,viscera of poultry,5 fish samples,and 27 surface water samples,12 ground water samples,13 drinking water samples,29 cropland soil samples.The lead content of them were determined,the dietary survey on lead intake was performed among the residents living near the mining area also.Results 53.68%(102/190) of the crop samples revealed higher lead contents,which were over the standard limit,especially for rice(47.52%) and leafy vegetables(100%).The lead contents for five eggs samples,two peanuts samples and thirteen fresh corns were qualified.36%(102/190)of the samples of meat and viscera of poultry revealed higher lead contents,which were over the standard limit,especially for liver and chicken intestine.The lead intake only through rice and vegetables reached 4.55 mg in one week,which was over the tolerance dose by 0.52 times.Conclusion The lead intake of the residents living near the lead-zinc mining area are mainly from crop and vegetables and poultry.Environmental lead pollution is serious in the investigated area and must be controlled as possible as early.

Objective To investigate the effect of bevacizumab on apoptosis of drug resistant nasopharyngeal carcinoma(NPC) cells in vitro.Methods The human nasopharyngeal carcinoma(NPC) cell line CNE2 and its cisplatin-resistant CNE2/DDP cells were treated with bevacizumab and DDP in various concentrations.The lethal effects of the both drugs and the apoptosis rates on CNE2/DDP cells were then measured separately with MTT assay and flow cytometry,the mRNA expressions of Bcl-2 and Bax in CNE2,CNE2/DDP and CNE2/DDP/Bev cells were detected with semi-quantitative RT-PCR.Results The killing rate in 10?g/ml bevacizumab group was similar to that of blank group(0.0?4.1% vs.5.2?4.3%,P=0.180),while the rates of combination of 10?g/ml bevacizumab and DDP(0.1?g/ml and 0.2?g/ml,separately) were higher than that of using DDP only(42.3?6.5% vs.34.4?5.4%,P=0.041;62.6?5.5% vs.50.0?5.9%,P=0.009).The apoptotic rate of CNE2/DDP,which was caused by combining 0.1?g/ml DDP and 10?g/ml bevacizumab,was much higher than what was produced by DDP alone(87.29?3.38% vs.50.58?8.83%,P=0.049).By means of semi-quantitative RT-PCR assay,the expressions of Bcl-2 mRNA in CNE2,CNE2/DDP and CNE2/DDP/Bev cells were 0.613,0.952 and 0.135,respectively.Meanwhile,the expressions of Bax mRNA were 0.665,0.387 and 1.751,separately.Conclusion Bevacizumab can greatly increase the drug sensitivity of CNE2/DDP cells to DDP;apoptosis is inhibited in MDR cells,but it can be promoted by bevacizumab.

Objective To investigate the feasibility, short-term efficacy and adverse effects of 125 I seed implantation guided by ultrasonography or CT in the treatment of recurrent rectal cancers. Methods A total of 15 patients (4 women and 11 men) with recurrent rectal cancer entered the study. Uneer epidural anesthesia, the patients were treated with 125 I seed implantation under the guidance of either transvaginal ultrasonography or CT scans. The prescribed matched peripheral dose (MPD) was 90~110 Gy, with an activity per seed of 0.50~0.70 mCi and the total number of sources implanted of 33~70. Chest and pelvic X-ray examinations were performed within 24~48 hours after implantation to determine whether or not seed misplacement or migration existed. An additional three-dimensional conformal radiation therapy with a 4~6 fields technique was required in 6 patients 4 weeks postoperatively, with 200~300 cGy/fx, 5 fx/week, up to a total dose of 4500~5 000 cGy. Additional chemotherapy with oxaliplatin, 5-fluorouracil and tetrahydrofolic acid for one treatment course was given in 2 patients. The patients were followed for 3~15 months and the tumors were evaluated by CT findings. Results Relief from pain was achieved at a mean of 7 days after procedure, offering a complete relief in 12 patients, a partial relief in 2, and no change in 1, the effective rate being 93%(14/15). Nine patients showed a complete remission, 2 showed a partial remission, 4 showed a progressive disease, the local control rate being 73%(11/15). Two patients died of the dissemination to lungs. In 1 patient 1 seed had migrated to the pelvic side-wall and did not cause any clinical morbidity in a follow-up of 12 months. Conclusion 125 I implantation in recurrence of rectum cancer guided by ultrasonography or CT was safety, minimally invasion, low morbidity and high efficacy, it was worth of development and promotion.

Objective To investigate the effect of Propess on cervical collagen remodeling and cervical ripening in full-term pregnancy.Methods 94 cases of mid-term pregnant women enrolled in obstetrics and gynecology of our department from January 2016 to January 2017 were divided into two groupaccording to the random number table method.47 cases of the control group, taking oxytocin intravenous infusion;observation group of 47 cases, taking propess suppository vaginal medication.Labor time, medication to labor time, cervical Bishop score, mode of delivery, postpartum hemorrhage and neonatal situation of two groups were compared.Results Compared with the control group, the Bishop score of the cervix was increased, the total effective rate of cervical ripening was improved, the labor was shortened, the time of medication was shortened, and the delivery rate of vaginal delivery was improved(P<0.05), while the two groups were bleeding, neonatal Apgar score and the incidence of fetal distress were not statistically significant.Conclusion It can promote cervical collagen remodeling, promote cervical ripening, thereby reducing the rate of cesarean sectionwith taking propess in the vaginal.

Objective To explore the clinical significance of experimental index in incomplete Kawasaki disease (iKD).Methods Eighty-eight cases of KD were reviewed,including iKD 36 cases (iKD group),complete KD(cKD) 52 cases (cKD group).The 88 cases were divided into traditional criterion group (43 cases) and supplement criterion group (45 cases).The experimental indexes of supplement criterion were compared between iKD group and cKD group.Results The rate of coronary artery lesion (CAL) in iKD group was significantly higher than that in cKD group [50.00％(18/36) vs.26.92％(14/52),P ＜ 0.05].Plasma NT-proBNP and cardiac troponin Ⅰ (cTnI) in CAL children (32 cases) in early were significantly higher than those in non CAL children (56 cases) [(468 ± 141) ng/L vs.(379 ± 120) ng/L and (0.95 ±0.22) μg/L vs.(0.49 ±0.15) μg/L,P ＜0.01].The diagnosis rates of KD in the 5th,7th,9th day in supplement criterion group were significantly higher than those in traditional criterion group [64.44％(29/45)vs.25.58％(11/43),84.44％ (38/45) vs.46.51％ (20/43),93.33％(42/45) vs.58.14％ (25/43),P ＜ 0.01].There was no statistical significance between iKD group and cKD group in C reactive protein,erythrocyte sedimentation rate,albumin,alanine aminotransferase,platelet,white blood cell,NT-proBNP and cTnI etc (P ＞ 0.05).There was no statistical significance between iKD group and cKD group in the positive rate of each experimental index (P ＞ 0.05).Conclusions There are some changes of supplement experimental index in acute phase of KD,but there is no statistical significance between iKD and cKD.Plasma NT-proBNP and cTnI are significantly higher in early KD.

Objective To observe the effect of ritodrine hydrochloride on peripheral blood and tocolysis rate of patients with threatened premature labor.Methods89 cases of patients with threatened premature labor were selected from October 2015 to September 2016 and randomly divided into two groups, research group with 45 cases treated with ritodrine hydrochloride and control group with 44 cases treated with epsom salt.The peripheral blood, extinction time of uterine contraction, extended days of pregnancy, postpartum hemorrhage, neonatal birth weight and tocolysis rate were compared between two groups.ResultsAfter treatment, CRH, NO, PGE2 and IL-8 of control group were obviously higher than research group, the difference was statistically significant (t=10.826,3.839,7.534,8.075,P<0.05).The extinction time of uterine contraction in control group was obviously longer than research group, while extended days of pregnancy and neonatal birth days in research group were obviously longer than control group, the difference was statistically significant (t=4.566,7.855,3.237,P<0.05).There was no significant difference in postpartum hemorrhage between two groups (t=0.889,P>0.05).The overall efficacy of tocolysis in control group was 70.5%, while that in research group was 86.7%, which was obviously higher than the control group, the difference was statistically significant (χ2=7.801,P<0.05).ConclusionRitodrine hydrochloride can effectively control uterine contraction factor in peripheral blood and extend gestational days of patients with threatened premature labor, so as to improve tocolysis rate and birth quality.

ObjectiveTo evaluate the suitability of Nordtest guideline in estimating measurement uncertainty of routine tests in clinical laboratory.MethodsData of clinical laboratory of Beijing Tongren Hospital were collected,which came from 176 days of Internal Quality Control ( IQC ) from July 2010 to December 2010 and 6 times of External Quality Assesment ( EQA ) of NCCL from 2009 to 2010.The combined and expanded uncertainties of 21meaurements (sodium, potassium, chlorine,calcium,phosphrous,glucose,urea nitrogen,creatinine,uric acid,total protein,albumin,total bilirubin,direct bilirubin, alanineaminotransferase, aspartateaminotransferase, alkalinephosphatase, lactate dehydrogenase,glutamyl transpeptidase,creatine kinase,triglyceride and total cholesterol) were evaluated according to Nordtest guideline.ResultsOf all the measurements,expanded uncertainty of direct bilirubin ( 17.69％ ) was the highest.For some enzymes such as ALT,AST,ALP and LDH,expanded uncertainties were all over 10％ markedly influenced by the calibrator uncertainty.Expanded uncertainty of triglyceride was 12.7％,also largely influenced by calibrator uncertainty,while that of total cholesterol was 6.96％.ConclusionsNordtest guideline is suitable to evaluate the measurement uncertainty of routine assays in clinical laboratory.However,calibrator uncertainty should be taken into account in the process of evaluation.

Objective: This paper investigates Shenmai Injection’s effect on the cellular immunity of patients with acute exacerbated chronic obstructive pulmonary disease (AECOPD). Methods: 92 cases of AECOPD patients are randomly divided into two groups----control group and treatment group, each with 46 patients. Patients in the two groups are given the same treatment such as anti-inflammatory, astiasthmatic, eliminating phlegm, inhale oxygen. Based on conventional treatment, the treatment group dissolves 40mL of Shenmai Injection in 250mL of injection glucose (5%). Such solution is dripped in vein continuously for two courses of treatment, with ten drops for a course of treatment and once a drop. Indexes of CD+3, CD+4, CD+8of peripheral blood T lymphocyte subsets and ratio of CD+4/CD+8 are tested before two weeks and after two weeks of the treatment, in order to discuss the effect of Shenmai Injection on the cellular immunity of patients with acute exacerbation of chronic obstructive pulmonary disease. Results: After two weeks' treatment, the indexes of CD+3, CD+4 raise up, the indexes of CD+8 go down, and the ratio of CD4+/CD8+ increases. In contrast, there is a significant difference for the patients before the treatment; So is the same with Indexes of CD+3, CD4+, CD8+ and ratio of CD+4/CD+8 to the patients in the treatment group and those in the control group after two weeks. Conclusion: Shenmai Injection can improve the AECOPD patient’s cellular immunity.

AIM:To investigate the effects of rolipram on the ability of learning and memory and the activity of PDE4 in hippocampus following the focal brain injury induced by ischemia-reperfusion in rats.METHODS:The cerebral ischemia-reperfusion injury model was made by middle cerebral artery occlusion(MCAO) in rats.The rats were randomly divided into sham-operated group,model group,and rolipram group.Rolipram was administered once a day(1 mg/kg,ip) from 6 h after the onset of the operation for 2 weeks.Then the learning and memory abilities were tested after Morris water maze and step-though training.The activity of PDE4 in hippocampus was evaluated by HPLC.RESULTS:In the Morris water maze test,compared to sham-operated group,the platform-finding time and swimming distance in model group were significantly longer(P
