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.

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 determine the plasma concentration of cytarabine(Ara-C) in children with leukemia and obtain dynamics parameters, and investigate the relationship between the parameters and clinical effect in order to provide the basis for optimization of Ara-C application. Methods Using highperformance liquid chromatogram (HPLC) to determine the plasma concentration of Ara-C, its metabolite Ara-U and infusion rate in 37 children with acute leukemia, their therapeutic reaction, remission, treatment-related infection, side-effect and long-term treatment effect were analyzed in statistic. Results Ara-C by 1～2 g/m2 intravenous drop infusion for 2 hours, the peak plasma concentration time was 2 h and peak concentration were (14.37-84.44)μmol/L, and the median was (41.42±22.80)μmol/L. The median infusion rate was 869.57at 30 minutes after Ara-C drip completion, its average level was (253.40±81.49) μmol/L, over six-times than Ara-C peak concentration. The median continuous complete remission time in 37 children was 29.8 months (5.0～53.1 months), 3y-DFS was (90.63±5.15)%. The therapy-related infection rate was 56.8 %(21/37),including three children (8.1 %) suffered from severe infection, but there was no therapy-related death and no children were off the protocol due to poor tolerance. Conclusion As post-remission treatment, high-dose Ara-C would not cause cumulation in vivo in children with acute leukemia and side-effect were slight. Ara-C could improve the long-term continuous complete remission rate and clinical cure rate for children with leukemia. Therefore, it was worth to apply in clinical.

Objective · To investigate the changes of neutrophils and lymphocytes during chemotherapy courses in children with high-risk neuroblastoma, as well as severe infection rate and its relationship with combination chemotherapy regimens in order to provide guidance to prevent infection in these children. Methods · A total of 45 cases of children with high-risk neuroblastoma, who were hospitalized in Xinhua Hospital from July 2012 to September 2015 were recruited. Reactions after chemotherapy and the results of routine blood tests on every 5 days during the whole chemotherapy circles were recorded. Follow-up visits were carried out to learn the infection occurrence. Results · The counts of neutrophils and lymphocytes dropped to the minimum at the 10th day or so during chemotherapy, then rised near the 15th day. Infections were negatively correlated with the numbers of neutrophils (r =-0.245) and lymphocytes (r=-0.227) at the 10th day. Persistent lymphopenia occured after the forth course of chemotherapy. Rate of grade Ⅳ bone marrow suppression after chemotherapy was 90%, and severe infection rate was 15.5%. There were significant differences in the rates of grade Ⅲ bone marrow suppression (P=0.008), grade Ⅳ bone marrow suppression (P=0.001) and severe infection (P=0.010) among the 3 combination chemotherapy regimens used in high-risk neuroblastoma children. Conclusion · Children with high-risk neuroblastoma had obviously high rates of bone marrow suppression and severe infection after chemotherapy, especially after cyclophosphamide+doxorubicin+vincristine regimens. More attention should be paid to this group of children and preventive measures were worthy of taking into account.
