Objective To study the relationship between salt consumption and hypertension in Chinese people,and provide basic information for developing intervention strategies.Method The data of 45 349 chinese residents aged 15 yrs and above from 2002 China National Nutrition and Health Survey was used.Results The hypertension prevalence was 18.2%.The prevalence of residents with high blood pressure value was 36.0%,which was 20.4% and 16.2% among men and women,respectively. Hypertension prevalence among people living in urban was higher than their counterparts living in rural.The prevalence of hypertension increased with salt consumption.As compared to people who consumed less than 6 g salt per day,after relative confounding factors adjusted,the prevalence ratio was 1.09,1.14 and 1.28 times,respectively,among people who averagely consumed 6～12 g,12218 g,and≥18 g salt per day,which was 1.13,1.11 and 1.30 times,respectively,among employment population.Conclusion The hypertension prevalence of chinese residents is quite high.There is significant relationship between salt consumption and hypertension.It is very important to strengthen the health education for preventing and controlling hypertension in Chinese residents.

Objective To study the time distribution of non-agriculture employed population spent in a working day in China, and to provide basic information for intervention strategies.Methods The data of 2002 China Nutrition and Health Survey were used. The information on daily activities including occupation,transportation,exercise,housework,sedentary activity and sleep was described.Results Non-agriculture employed population spent 8.41 h,0.58 h,0.09 h,3.11 h,1.40 h and 7.89 h on occupation, transportation,exercise,sedentary activity,housework and sleep,respectively.Administrator,technologist and clerks spent less time on occupation activity than service workers,production and transportation workers and others did,and they spent more time on sedentary activity.Male spent more time on occupation activity and less time on housework and sleep than female did.People in rural area spent more time on occupation activity than those in urban area,but less time On transportation and sedentary activity.Conclusion Differences in time use among different employed groups,gender and area were found,which should be considered when intervention measure is developed.

OBJECTIVETo explore the effectiveness and safety of transcutaneous electrical acupoint stimulation (TEAS) combined with infusion of propofol in anodynia bronchoscopy.

METHODSNinety patients who received selective bronchoscopy were randomized into a group of compound TEAS with infusion of propofol (group A), a group of compound fentanyl with propofol (group B) and a group of simple propofol (group C). In group A, the plaster electrode stimulation was applied at bilateral Hegu (LI 4), Laogong (PC 8), Neiguan (PC 6) and Waiguan (TE 5). The anesthesia was induced after 20 min of stimulation till the end of examination. In group B and group C, the electric stimulation was not adopted. In group B, before anesthesia, fentanyl 1 microg/kg was injected intravenously. Afterwards, the intravenous infusion of propofol was used in the the three groups for anesthesia. The mean arterial pressure (MAP), heart rate (HR), saturation of pulse oximetry (SpO2) and respiratory rate (RR) were recorded at different time points. The induced dosage and total dosage of propofol, examination time, the awakening time and adverse reactions were observed in the patients of each group.

RESULTSThe difference in examination time was not significant among the three groups (P > 0.05). The postoperative awakening time in group A was earlier than that in group B and group C [(220.3 +/- 110.5) s vs (285.6 +/- 109.4) s, (290.1 +/- 105.1) s, both P < 0.05]. The total dosage of propofol in group C was larger than those in group A and group B [(288.5 +/- 26.7) mg vs (225.1 +/- 30.2) mg, (230.4 +/- 29.3) mg, both P < 0.05]. The induced dosage in group C was larger than those in group A and group B [(193.7 +/- 42.3) mg vs (152.3 +/- 36.1) mg, (155.4 +/- 40.5) mg, both P < 0.05]. Every life physical sign in group A during examination was more stable as compared with that in group B and group C. The incidence of hypotension and bradycardia in group A were lower than those in group C [3.3% (1/30) vs 26.7% (8/30), 0% (0/30) vs 20.0% (6/30), both P < 0.05]. The adverse incidence of oxygen supply in group A was lower than that in group B [6.7% (2/30) vs 33.3% (10/30), P < 0.05]. Intraoperative awareness and improper memory did not happen in postoperative investigation.

CONCLUSIONIn the transcutaneous electrical acupoint stimulation combined with infusion of propofol in anodynia bronchoscopy, the physical sign of patient is stable with less adverse reactions. This method reduces anesthetic dosage and shortens the postoperative awakening time, which can be effectively applied in bronchoscopy.

Objective To explore the safty and feasibility of transrectal ultrasound guided transperineal seminal vesicle biopsy in the evaluation of clinical staging of prostate cancer.Methods Retrospectively study 57 suspected prostate cancer patients with seminal abnormality during 2010.7-2015.1,age ranged from 50 to 78 years,average 65 ±7 years,serum total prostate specific antigen (tPSA) 3.2-131.1 μg/L, average (23.7 ± 11.3) μg/L.Twenty-two cases had palpable prostate nodules through rectal examination.All the 57 patients underwent ultrasound and template guided transperineal prostate and seminal vesicle puncture biopsies.Results Forty-four cases out of 57 found prostate cancer cells in biopsies, and 32 cases had seminal vesicle invasion (positive group) while the other 12 were negative.Twenty cases had been performed prostatectomy in the positive group and their post-operative pathological examination all showed prostate cancer with seminal vesicle invasion.Eleven cases in the negative group had been performed prostatectomy ,and 2 cases showed seminal vesicle invasion.The clinical stages of all cases in the positive group were considered as T3b both pre-operatively and post-operatively.In the negative group however, 11 cases were considered as T2 stage pre-operatively,while 2 cases were increased to T3b stage post-operatively.The sensitivity of puncturing seminal vesicle was 91％ (20/22) ,specificity was 100.0％ (9/9).Positive predictive value was 100.0％ (20/20),while negative predictive value was 82％ (9/11).All the 57 cases did not present fever after puncture biopsies, while 23 cases presented hematuria (40％) ,20 cases presented hemospermia (35％) and 1 case presented urinary retention (2％).Conclusions Transrectal ultrasound-guided transperinealseminal vesicle puncture is safe and reliable, it helps to improve the accuracy of pre-operative staging.

Objective To analyze the clinical and histopathologic characteristics in children with subcutaneous panniculitis-like T-cell lymphoma(SPTCL),and explore the pathological diagnosis and differential diagnosis,in order to boost paediatricians to better understanding the disease.Methods One case was diagnosed SPTCL with over 2 years protracted course of fever and multiple skin lesions.The evolvement of clinical presentation,the misdiagnosed experience,the histopathological features,the immunohistochemical results and T cell receptor(TCR)gene cloning rearrangement were observed.The related literatures published were reviewed.Results Skin biopsy showed that the histopathologic findings were limited within subcutaneous fatty tissue,the atypical lymphocytes characteristically rimmed individual fat cells in a lace-like pattern.Immunophenotypic studies showed CD45,CD45RO,CD3,CD5,T cell intracellular antigen-1(TIA-1)and perforin usually expressed possitive,while CD10,CD20,CD56,CD68,epithelial membrane antigen(EMA)and cytokeratin(CK)were negative,implying tumor cells derived from T-cell.The results of TCR gene rearrangement as following:IgH FR2(+),FR3A(-);TCR ? JVI(-),JVII(+);TCR? JD1(-),JD2(-).Although the protocol of children's T-cell Non-Hodgkin lymphoma was administrated,the treatment outcome was poor.Conclusion SPTCL is a special primary cutaneous lymphoma with poor prognosis,skin biopsy of suffered lesion is an important method for the diagnosis of SPTCL children with unclear recurrent fever and multiple skin lesions.

Objective: To observe the clinical effects of Shu-acupuncture method in Nei Jing (Classic of Internal Medicine) in the treatment of shoulder and arm pain. Methods: A total of 90 patients with shoulder and arm pain were randomly divided into an observation group and a control group, 45 cases in each group. The treatment of Shu-acupuncture method in Nei Jing (Classic of Internal Medicine) was adopted in the observation group, routine acupuncture was used in the control group. The two groups were treated once every day, with 5 treatments as one course, and a 2-day rest between two courses. After 3 courses, pain was assessed by visual analog scale (VAS), and the clinical effects were compared between the two groups. Results: After the treatment, VAS scores were significantly changed in both groups (both P<0.01). The VAS score was lower in the observation group than that in the control group, with a statistical difference between the two groups (P<0.05). The total effective rate was 100% in the observation group, versus 91.1% in the control group, the difference was statistically significant (P<0.05). Conclusion: The therapeutic effect of Shu-acupuncture method in Nei Jing (Classic of Internal Medicine) is better than that of routine acupuncture in treating shoulder and arm pain.

Objective To study the biological characteristics of arsenic resistance cell model chronic arsenic exposure human bone marrow mesenchymal stem cells (CAsE-hFBMSCs) and discuss the consequence of chronic arsenite exposure to human mesenchymal stem cells (hFBMSCs). Methods hFBMSCs cultivated under general conditions,hFBMSC cell survival rate was detected in 48 hours with arsenite toxicity test under different doses arsenic [0(control),0.25,0.50,1.00,2.00,4.00,8.00,20.00,40.00,80.00,120.00 μmol/L]of the fist 2-generation(P2). According to the test results,1.00 μmol/L sodium arsenite was chosen to stimulate hFBMSCs for 14 weeks as experimental group,simultaneous 0 μmol/L sodium arsenite as the control group. And then,the phenotype was detected by fluorescence-activated cell sorting,and the cell cycle by flow cytometry. Finally,the cell malignant transformation was detected by soft-agar assay. Results Arsenite low than 10 μmol/L promoted cell proliferation,but inhibited cell proliferation when exceeding 10 μmol/L. Half of the lethal dose (LC_(50)) in experimental and control groups were (89.42±0.64),(52.48±0.71)μmol/L. The difference between two groups was statistically significant(t = 123.89,P < 0.05). The phenotype of CAsE-hFBMSCs was CD29,CD90,CD166 positive and CD34,CD45 negative. The phenotype of CAsE-hFBMSCs was the same as the control. Comparing to control group[(8.44±0.45)%,(9.14μ0.14)%,(82.42±0.60)%],G2/M phage[(17.72±5.47)%]and S phage [(25.34±3.36)%]cell increased,G0/G1 phage[(56.96±8.83)%]cell decreased in P2 CAsE-hFBMSCs. The cell cycle became nearly the same as the control group after adaption. CAsE-hFBMSCs did not show clone formation in soft agar clone formation assay. Conclusion Long last and low level exposure to arsenite does not influence the biologic features of hFBMSCs.
