Objective To study the effects of salt sensitivity on evolution of blood pressure and develope- ment to hypertension from adolescents to youth.Methods A baseline survey was carried out in 4623 adolescents aged 6-15 years old in Hanzhong rural area in 1987,310 of them were recruited for determination of salt sensitiv- ity using the tests of oral saline load and furosemide sodium-volume depletion.Salt sensitivity (SS) were diag- nosed in 101 while 209 subjects as no-sah sensitivity (NSS).This cohort of adolescents were followed up for av- erage 18 years.Results The response rate for this cohort of adolescents was 71.9%.At the end of follow up period,BP in subjects with baseline SS was higher in youth than that in NSS (SBP:122.9?13.1 vs 117.3?12.4, P

OBJECTIVETo summarize and analyze the compatibility laws for acupoint selection of acupuncture in treating diabetic gastroparasis (DGP) in modern literatures of clinical researches.

METHODSRetrieved were literatures related to treating DGP by acupuncture or acupuncture combined other therapies from PubMed, CNKI, and WF from 1982 to 2014. Analyzed were frequency of acupoint use, meridians selected acupoints belonged to, regions selected, association laws of selected compatible acupoints.

RESULTSRetrieved were 35 with compatibility frequencies more than 15 listed as follows: compatibility frequency of Zusanli (ST36) and Zhongwan (CV12) was 33 (94.29%); compatibility frequency of Zusanli (ST36) and Neiguan (PC6) was 23 (65.71%), compatibility frequency of Zhongwan (CV12) and Neiguan (PC6) was 22 (62.86%), compatibility frequency of Zusanli (ST36), Zhongwan (CV12), and Neiguan (PC6) was 22 (62.86%); compatibility frequency of Zusanli (ST36) and Sanyinjiao (SP6) was 16 (45.71%); compatibility frequency of Zhongwan (CV12) and Sanyinjiao (SP6) was 16 (45.71%); compatibility frequency of Zusanli (ST36), Zhongwan (CV12), and Sanyinjiao (SP6) was 15 (42.86%). Meridians selected acupoints belonged to were sequenced as Foot Yangming Stomach channel, Ren channel, Foot Taiyang Bladder channel, and so on. Acupoints selected were mainly in lower limbs, chest and abdomen, waist and back. The compatibility of Zusanli (ST36) and Zhongwan (CV12) was the most often used with the highest frequency.

CONCLUSIONSThe compatibility laws for acupoint selection of acupuncture in treating DGP were mainly dominated as upper-lower selection, three regions selection, local selection, anterior-posterior selection. The compatibility laws for acupoint selection of acupuncture along meridians were mainly dominated as the convergence points and exterior-interior meridian points.

Blue light has been widely used for the treatment of neonatal hyperbilirubinemia since the 1950s. Neonatal phototherapy can decrease plasma unconjugated bilirubin level, thus preventing bilirubin encephalopathy, and greatly reduces the exchange transfusion rate. Generally, it is accepted that the side effects of neonatal phototherapy are not serious and seem to be well controlled, however recent research has provided new evidence. The short-term side effects of phototherapy include interference with maternal-infant interaction, imbalance of thermal environment and water loss, electrolyte disturbance, bronze baby syndrome and circadian rhythm disorder. In addition, phototherapy may be associated with some long-term side effects such as melanocytic nevi and skin cancer, allergic diseases, patent ductus arteriosus and retinal damage. Therefore, it is necessary to develop evidence-based guidelines, new light devices and alternative agents, as well as individualized treatments, to minimize the side effects of phototherapy.

OBJECTIVETo investigate the effects of potassium and calcium supplementation in table salt on reduction of arterial blood pressure and sodium metabolism in adolescents with higher blood pressure.

METHODSA single blind placebo-controlled trial was carried out for two years in 220 adolescents with higher blood pressure, aged 18 - 22 years, who were randomly divided into supplementary group (n = 110) and control group (n = 110). Each of the subjects in the supplementary group and their family members was given 10 mmol of potassium and 10 mmol of calcium mixed in their table salt daily for 24 months.

RESULTSNight urinary sodium and potassium excretion increased (urinary Na(+), P < 0.05; urinary K(+), P < 0.01) and blood pressure lowered by 5.3 mm Hg/1.8 mm Hg in average from the baseline in the supplementary group two years after potassium and calcium supplementation, as compared with that in the control group increased by (1.3/1.7) mm Hg.

CONCLUSIONSAdequate supplement of potassium and calcium in daily table salt intake was an effective way to prevent form hypertension and could promote their urinary sodium excretion and reduction of arterial blood pressure in adolescents with higher blood pressure.

OBJECTIVETo investigate the parents' compliance in non-hospital settings during the operation of expressed breast milk bank.

METHODSIn September 2014, a questionnaire survey was carried out to investigate the parents' willingness about feeding the inpatient neonates with maternal expressed breast milk, to evaluate the effectiveness of the breast milk feeding supporting system, and to monitor the compliance in non-hospital settings during the delivery of maternal expressed breast milk. Improvements in education were made according to the results. A second survey was done in September 2015.

RESULTSA total of 340 questionnaires were sent out, and 338 usable questionnaires were returned. According to the time when the questionnaires were sent out, they were divided into two groups: 2014 group (n=229) and 2015 group (n=109). The age of most mothers was 20-30 years in the 2014 group and 30-40 years in the 2015 group. Most mothers delivered at the West China Second Hospital of Sichuan University in both groups, but the 2015 group had a significantly higher proportion than the 2014 group (74.3% vs 61.6%; P<0.05). Guidance was given to mothers in the presence of insufficient breast milk production in both groups, but the 2015 group had a significantly higher proportion than the 2014 group (91.7% vs 79.9%; P<0.05). Both groups had good family compliance in the collection, storage, and transport of breast milk. There were no significant differences in their compliance with washing hands, sterilizing instruments, and using a clean special refrigerator between the two groups. The expressed breast milk was transported strictly according to the procedure in both groups, but the 2015 group had a significantly higher proportion than the 2014 group (100% vs 87.1%; P<0.05).

CONCLUSIONSBefore and after improvements in the health education, most parents have good compliance in the collection, storage, and transport of breast milk.

OBJECTIVETo explore young hypertensive people's vascular endothelial dysfunction and the early atherosclerosis changes.

METHODSRural youth subjects aged 20 to 35 in 6 villages were randomly selected from 20 villages of 3 townships, including Qili, Laojun and Shayan, in Hanzhong, Shanxi, China, from March to April of 2005, to survey their blood pressure and other related factors. 97 subjects with high blood pressure (hypertensive group) were detected while 400 with normal blood pressure (normal group). We measured their brachial artery flow-mediated vascular endothelial-dependent diastolic function (FMD) and the carotid intima-media thickness (IMT) by high resolution vascular ultrasound method, and other biochemical indexes.

RESULTSThe body mass index (BMI) ((24.7 ± 4.3) kg/m²), waistline ((84.1 ± 11.7) cm), hipline ((92.5 ± 7.4) cm), TC ((4.6 ± 0.8) mmol/L), LDL-C ((2.8 ± 0.5) mmol/L), TG ((1.7 ± 1.1) mmol/L) and the blood insulin (INS) ((8.6 ± 4.4) mIu/L) were all significantly increased in young hypertensive group than those in normotensive group (respectively were (22.1 ± 3.0) kg/m(2), (76.7 ± 8.9) cm, (88.9 ± 5.6) cm, (4.3 ± 0.7) mmol/L, (2.6 ± 0.4) mmol/L, (1.4 ± 0.8) mmol/L and (6.9 ± 2.1) mIu/L) (P < 0.05). The FMD of the brachial artery in hypertensive group was markedly lower than normal group ((0.103 ± 0.04)% and (0.117 ± 0.05)%, P < 0.05). The IMT of two groups were (0.49 ± 0.07) mm and (0.48 ± 0.07) mm, but there was no statistically significant differences (P > 0.05).

CONCLUSIONYoung hypertensive people with a few cardiovascular risk factors earlier appear dysfunction of the flow-mediated vascular endothelial-dependent dilation, which is prior to the increase in carotid IMT.

OBJECTIVEPeripherally inserted central catheter (PICC) is widely used to provide a long-term access for the administration of total parenteral nutrition and medications. Catheter-related infections (CRI) are common complications of PICC. The purpose of this retrospective study was to investigate the role of low-dose heparin added to the total nutrient admixture (CTNA) in the prevention of CRI.

METHODSEighty-three neonates who underwent PICC received TNA with (heparin group, n=43) or without heparin (0.5 U/mL) (control group, n=40). The incidence of CRI was compared between the two groups.

RESULTSThe incidences of catheter obstruction (5% vs 20%) and the catheter-tip colonization (2% vs 18%) in the heparin group were significantly lower than those in the control group (p<0.05). None of the neonates in the heparin group had clinical evidence of catheter-related bloodstream infection, but 5 cases in the control group (p<0.05).

CONCLUSIONSThe administration of low-dose heparin in TNA may decrease the incidences of catheter obstruction and CRI.
