Objective To investigate the level changes of plasma soluble intercellular adhesion molecule-1(sICAM-1), endothelin(ET) and Nitric oxide(NO) and the effects of perindopril on their levels in elderly patients with essential hypertension. Methods Enzyme linked immunosorbent assay(ELISA), radioimmunoassay and nitrate reductase method were used to respectively measure the plasma levels of sICAM-1, ET and NO in 63 elderly patients with mild to moderate essential hypertension before and after perindopril treatment and 40 normotensive elderly individuals. Results Elderly hypertensive patients exhibited significantly higher plasma levels of sICAM-1 and ET, and lower plasma level of NO than normotensive elderly individuals did(P

Objective To investigate the changes of fractional exhaled nitric oxide (FENO)) and their relation with lung function in bronchial asthma.Methods FENO and forced expiratory volume in the first second (FEV1) were measured during the periods of acute onset,chronic persistence and paracmasis in 54 patients with asthma and 19 healthy persons.Results There were significant differences in the levels of FENO and FEV1 among the course of acute onset [(57.59 ± 32.24) ppb and (1.72± 0.33) L],chronic persistent course [(40.02 ± 15.68) ppb and (2.41 ± 0.23) L],paracmasis [(26.71±6.07) ppb and (2.82±0.29 )L]and control[(14.74±3.42 ) ppb and (2.93±0.13)L] (F=19.555,163.096,P＜0.01) except for the levels of FEV1 between paracmasis and control group(P＞0.05).The negative correlation between FENO and FEV1 was found in the course of acute onset(r=- 0.666,P =0.005 ),but not in the chronic persistent course ( r =- 0.288,P =0.176) and paracmasis(r=-0.246,P=0.457).Conclusions The level of FENO is increased and may be useful to evaluate control degree in patients with asthma.

[ Objective ] To supply a technological evidence for the rapid reproduction of Andrographis paniculata (Burm. f.) Nees (APN). [Methods] Different explants from sterile seedling of Andrographis paniculata (Burm. f.) Nees were cultured in vitro to induce the production of fascicular buds. [ Results ] Cotyledon with nodes and half cotyledon with nodes were the most suitable explants for culture, and the budding rate was 100% and over 90% respectively. 6-Benzylaminopurine (BA) in the concentrations of 0.5 ~ 1.0mg/L were beneficial for the reproduction and growth of buds. The age of explants had no correlation with budding. The optimal rooting medium was MT (Murashige and Tucher) medium added with Img/L NAA (naphthaleneacetic acid) or IBA (indolebutyric acid). A highest rooting rate as much as 61.9% was achieved after 10 days of culture. [Conclusion] An effective plant regeneration system has been established for explants of Andrographis paniculata (Burm. f.) Nees.

AIM: The present study is to investigate the inhibitory effect of the transfer of replication-defective retroviral recombinant plasmid encoding a wild-type P16 ink4a gene on the formation of restenosis after rabbit carotid arterial injury in vivo.METHODS:A replication-defective retroviral recombinant plasmid encoding wild-type gene P16 ink4a was constructed and the packaged high titer virus stock was obtained. It was transferred into the rabbit carotid arterial wall immediately after injury. The P16 ink4a mRNA expression in the arteries was examined by Northern blot and in situ hybridization. The effect of overexpression of the P16 ink4a gene on arterial intima hyperplasia was determined by pathophysiological method. RESULTS: The exogenous P16 ink4a could be effectively transferred into injured arterial wall by retroviral recombinant plasmid and the gene products could inhibit smooth muscle cells proliferation (11.80?3.54 vs 25.20?5.12,P

Objective To verify the correlation between rs17118 polymorphism of xyluloknase homolog (XYLB) gene and risk of ischemic stroke in a Chinese Han population.Methods A case-control study design was used.The case group was the patients with first-ever ischemic stroke and the control group was the healthy subjects from hospital physical examination.Taqman probe fluorescence quantitative polymerase chain reaction technique was used to detect the genotype distribution of rs17118 C/A polymorphisms.Results A total of 475 patients with ischemic stroke and 483 controls were enrolled in the study.The proportion of hypertension (67.9％ vs.22.2％;x2 =292.982,P ＜ 0.001) and diabetes (24.2％ vs.7.3％;x2 =25.864,P ＜ 0.001),as well as the levels of triacylglycerol (1.649 ± 1.126 mmol/L vs.1.157 ±1.480 mmol/L;t=3.592,P＜0.001),and low-density lipoprotein cholesterol (3.499 ± 1.163 mmol/L vs.3.105 ± 0.627 mmol/L;t =-6.227,P ＜ 0.001) in the case group were significantly higher than those in the control group,but the total cholesterol level was significantly lower than that in the control group (5.144 ± 1.296 mmol/L vs.5.491 ± 1.335 mmol/L;t =4.650,P ＜ 0.001).The AA genotyp e (11.4％ vs.7.5 ％;x2 =6.136,P =0.016) and A allele (32.3 ％ vs.26.4％;x2 =8.093,P =0.005) frequencies in the case group were significantly higher than those in the control group.Multivariatelogistic regression analysis showed that after adjusting for traditional risk factors,the risk of ischemic stroke in AA genotype carriers was 1.97 times of the CC genotype carriers (odds ratio 1.971,95％ confidence interval 1.040-3.736,P=0.038).Conclusions The rsl7118C/A polymorphism of XYLB gene may be associated with the risk of ischemic stroke in the Chinese Han population.

Objective To investigate the status of treatment institution selection and its influencing factors in elderly patients with chronic diseases in a community in Changsha.Methods By using systematic sampling,400 elderly patients with chronic diseases from June to August 2012 were included in the investigation by questionnaires.The influencing factors were analyzed by binary logistic regression model or multinomial logistic regression model on the basis of the numbers of response variables.Results In mild conditions in self-consciousness,more than half of the elderly patients with chronic diseases (206 cases,51.5％) preferred community health service centers including private clinics (67 cases,16.8％),municipal hospitals (92 cases,23.0％),third-grade class-A hospitals (35 cases,8.8％).In serious conditions in self-consciousness,patients preferred third-grade class-A hospital (238 cases,59.5％) and municipal hospitals (162 cases,40.5％),no one selected the private clinics or community health service center (x2=443.240,P＜0.001).The analysis of impact factors for the first treatment institution selection in patients with serious conditions in self-consciousness showed that,compared with patients selecting the municipal hospital,the following personnel preferred to choose third-grade class-A hospital:patients in the staff remaining in positions (OR=32.38) and retirees (OR=15.17),patients with monthly income more than 5,000 yuan (OR=134.28),rural cooperative medical patients (OR=661.42),patients with highly trusting in community health service centers (OR=4.23),patients with BP and serum glucose determination at a frequency of once a month to every three months (OR=83.93),patients unknowing the telephone numbers of community health service centers(OR=3.02)and patients living far away from community health service centers (OR=15.70),patients with little information about community health service centers (OR=1.62).The analysis of impact factors for the first treatment institution selection in patients with mild conditions in self-consciousness showed that,compared with patients selecting the private hospitals,the following personnel preferred to choose community health service centers:patients with primary education level (OR=0.15),retired persons (OR=0.14),patients with higher health attention (OR=0.26),while persons with less health attention (OR-10.65) and patients living far away from community health service center (OR =5.22) were more willing to choose the private hospitals.Conclusions Patient selection for treatment agencies is affected mainly by the perceived severity,in addition,age,education level,employment status,income,health insurance type,trust and understanding on community health services centers,and the emphasis on health and the distance from community health services centers.

Objective To investigate the application of colostomy care products in managing the leakage around PTCD drainage tube, and to discuss its clinical effect. Methods A total of 56 patients with malignant obstructive jaundice, who had received PTCD and suffered from postoperative leakage around PTCD drainage tube, were randomly and equally divided into the study group (n=28) and the control group (n=28). The colostomy care powder, the skin protective film and the colostomy bag were used for the patients of the study group, while iodophors, sterile gauze and mupirocin ointment were employed for the patients of the control group. The incidence of irritant dermatitis around PTCD drainage tube, the degree of comfort to the indwelling tube judged by the patient, and the nursing workload for PTCD drainage tube were determined, and the results were compared between the two groups. Results The incidence of irritant dermatitis around PTCD drainage tube in the study group was obviously lower than that in the control group. And the degree of comfort to the indwelling tube judged by the patient in the study group was much higher than that in the control group. The differences between the two groups were statistically significant (P<0.05). Conclusion Combination use of colostomy care powder, skin protective film and colostomy bag can effectively reduce the incidence of irritant dermatitis around PTCD drainage tube and improve the patient’s condition. Therefore, this method is worthy of popularization in clinical practice.

Objective To analyze the variations of glycerol-3-phosphate dehydrogenase 1 like gene (GPD1-L) and address the association with sudden m anhood death syndrom e (SMDS).

The genotype frequency and allele frequency w ere analyzed statistically. Results There w ere tw ovariants in the SMDS group, c.465C>Tand c.*18G>T, the latter existed certain degree difference of genotype distribution and allele frequency betw een the SMDS group and the control group, but there was no statistically significant (P>0.05). Conclusion The relation be-tw een gene m utation of GPD1-L and the occurrence of Chinese SMDS deserves a further research.

Objective To investigate the impact of 1,25(OH)2D3 on histological changes and activation of STAT3 in BLM?induced pulmonary fibrosis mice. Methods 30 male C57BL/6 mice were randomly divided into control group ,BLM group and BLM+VD group. Mice in BLM group and BLM+VD group received intratracheal injection of BLM(3 U/kg). Control group were intratracheally injected equal volume of sterile saline. From the first day after the surgery,mice in BLM+VD group received intraperitoneal injection of VD (5μg/kg·d). After 21 days, H&E and Masson′s trichrome staining were carried out. Aschroft score were used to evaluate histological changes in lungs. IL?6,IL?4 and INF?γin BALF were assessed by Elisa. p?STAT3,α?SMA and Collagen I were detected by western blot (WB) and immunohistochemistry. Results Fibrosis score and level of α?SMA,Collagen I in BLM group were significantly higher than that in control group (P < 0.05). However ,treatment with VD effectively at?tenuated fibrosis (P<0.05). IL?6 and IL?4 increased while INF?γwas decreased in BALF of BLM group (P<0.05). VD could ameliorate these changes. Upregulation and neuclear translocation of p?STAT3 were observed in BLM group,while VD intervention could inhibit phosphorylation of STAT3. Conclusions VD attenuate BLM?induced pulmonary fibrosis and regulate inflammatory cytokines probably by blocking STAT3 activation.

OBJECTIVETo compare the clinical effect of glucocorticoids and NSAID in the treatment of partial splenic embolization syndrome.

METHODSSixty patients with cirrhosis and spleen hyperactivity who developed partial splenic embolization syndrome after partial splenic embolization with Seldinger technique were randomized equally into two groups to receive treatments with intravenous dexamethasone or oral nonsteroidal anti-inflammatory drugs (NSAIDs). White blood cell counts, liver functions, fever duration, abdominal pain duration, hospital stay, and occurrence of upper gastrointestinal hemorrhage and spleen abscess were recorded and analyzed.

RESULTSIn dexamethasone group, the average fever duration, abdominal pain duration, and hospitalization days was 3.36∓2.31, 7.39∓4.00, and 11.48∓3.29 days, respectively, significantly shorter than those in NSAIDs group (5.72∓3.83, 9.59∓4.22, and 15.07∓7.93 days, respectively, P<0.05). Seven days after the operation, white blood cell count (×10(9)=L) significantly increased from 4.23∓5.09 to 8.49∓3.53 in dexamethasone group (P<0.05), and from 3.21∓1.33 to 6.52∓2.37 in NSAIDs group (P<0.05); the increment was more obvious in dexamethasone group (P<0.05). The two groups of patients showed no significant difference in liver functions after the operation. None of the patients developed upper gastrointestinal hemorrhage or spleen abscess.

CONCLUSIONIntravenous dexamethasone produces better therapeutic effect than oral NSAIDs in the management of partial splenic embolization syndrome.
