Objective To explore the association of osteoporosis with blood pressure variability in elderly patients with hypertension complicated by osteoporosis, as well as its mechanisms. Methods A total of 189 elderly patients with hypertension were selected. According to the diagnostic criteria for osteoporosis, the patients were divided into three groups. 24-hour ambulatory blood pressure and IL-6 were detected in all the patients, and then compared among different groups. Results For the three group, there were statistical differences in levels of IL-6 and blood pressure variability (P < 0.05). Blood pressure variability was negatively correlated with BMD (P < 0.05). 3. IL-6 was positively related with blood pressure variability (P < 0.05), but had a negative correlation with BMD (P < 0.01). IL-6 had significant statistical differences among different sexes (P < 0.01). Conclusions Osteoporosis is closely associated with blood pressure variability in the elderly patients. IL-6 and blood pressure variability may play a synergistic role in the process of osteoporosis; and IL-6 may be a risk factor for postmenopausal osteoporosis in women.

Objective:To establish an analytical method for the identification of donkey-hide gelatin in Fufang Ejiao Buxue gran-ule.Methods:The identification of donkey-hide gelatin in Fufang Ejiao Buxue granule was established by rapid resolution liquid chro -matography (UPLC) coupled with triple quadruple mass spectrometry (QQQ-MS).Results: The characteristic molecular peaks of donkey-hide gelatin were detected in ten batches of commercial samples .Conclusion:The present method is specific , precise and reli-able, and suitable for the identification of donkey-hide gelatin in Fufang Ejiao Buxue granule .The method provides scientific reference for the study of quality control method for gelatin ingredients in Chinese patent medicines .

OBJECTIVETo assess the role of oxidative metabolism and nitric oxide synthesis for elucidating their pathophysiological mechanisms in a Tibetan patient with essential hypertension.

METHODSThe serum levels of total superoxide dismutase (T-SOD), malondialdehyde (MDA), total antioxidant capacity (T-AOC), nitric oxide (NO) and nitric oxide synthase (NOS) were assayed in sixty native Tibetans (thirty hypertensive patients and thirty healthy volunteers as control).

RESULTSThe levels of T-SOD, T-AOC, NO and NOS were significantly lower in the patient group than in the control group (P < 0.01); MDA was significantly higher in the patient group than in the control group (P < 0.01). The level of MDA had a strong negative correlation with T-SOD, T-AOC, NO and NOS (r = -0.82, -0.76, -0.79, -0.73, respectively, P < 0.001 for all).

CONCLUSIONTibetan patients with essential hypertension (EH) may have underlying oxidative metabolism dysfunction and depressed NO synthesis, both responsible for the hypertensive process.

Objective To investigate the correlation of serum(SF)and hepcidin(Hepc)level with cardi-ac function and chronic heart failure(CHF).Methods A total of 80 elderly patients with CHF who had received treatment in our hospital from October 2015 to February 2017 were assigned to CHF group and 80 patients without heart failure were assigned to a control group. Serum SF and hepidin levels in both the groups were measured and compared.Results Serum hepidin and hs-C-reactive protein levels were all significantly higher in CHF group than in the control group[(69.58 ± 27.16)ng/ml vs.(128.46 ± 33.28)ng/mL;(97.16 ± 16.81)ng/mL vs.(54.12 ± 15.76)ng/mL;(3.3 ± 1.64)mg/L vs.(2.78 ± 1.36)mg/L].Multiple logistic regression analysis showed that SF was an independent protective factor for CHF(P < 0.05);Hepc and hs-CRP were independent risk factors for CHF (P<0.05).Conclusions Serum hepcidin and hs-C-reactive protein may be risk factors for chronic heart failure. Measurement of serum hepidin and hs-CRP levels is helpful for early prevention and treatment of heart failure.

Objective To evaluate the nutrional status and malnutrition risks of hospitalized children with acute lymphoblastic leukemia (ALL),provide nutrition support for subsequent treatment,lower nutritional risks and improve therapeutic effects;to complete the statistical analysis of height and weight across age through data normalization.Methods A total of 592 children diagnosed ALL from August 2014 to September 2016 at Beijing Children's Hospital were enrolled,and the directly measured height and weight which reflected the nutritional status of children were collected and normalized.Nutritional risk screening was completed by STAMP screening tool and the nutritional status was evaluated by three Z scores HAZ＜-2,WAZ＜-2 and WHZ＜-2.The effects of nutrition intervention were investigated by weight,hemoglobin and albumin changes between before and after L-asp treatment.Results The Z score test showed that there was no significant difference between the nutritional status of pretreatment ALL patients (0.34％ growth retardation,2.36％ lower body weight,0.17％ emaciation) and normal healthy children (3％ malnutrition);after comparing the STAMP nutritional risk assessment and t test results for children with ALL,it was found that the proportion of children with high malnutrition risk (score≥4) was 9.71％,which had a strong correlation with body mass index;the children with body mass index less than 0.80 (50％ children having malnutrition) or greater than 1.30 (20％ children having malnutrition) had a higher risk of malnutrition,and the body mass indexof the high-risk group (0.852 kg/m2) were significantly lower than that of the low risk group (1.051 kg/m2,score ≤ 3);there were significant differences in height and weight between children with STAMP ≤ 3 and STAMP ≥ 4 (all P ＜0.05) Nutritional interventions made no significant weight change during treatment;For children with STAMP ≤3 and STAMP ≥4 in L-asp treatment,the hemoglobin value changed from (87.46± 19.27) g/L to (95.12±13.51) g/L and (101.55±21.97) g/L to (95.05±11.22) g/L respectively (all P=0.001);The albumin of children with STAMP≤3 changed from (40.63±4.149) g/L to (41.20±5.266) g/L in treatment and that of children with STAMP ≥4 changed from (40.96±8.429) g/L to (42.17±3.574) g/L in treatment (P=0.20,0.05).Conclusion There are no obvious indications of malnutrition in children with ALL,but nearly 10 ％ of them have malnutrition risks.Special dietary guidance is needed during the treatment.Nutrition intervention is effective in the treatment of L-asp.Normalized data is more convenient to use in statistical analysis with more accurate results,which can be used as a supplementary method for cross-age group statistical analysis of children's height,weight and other parameters.
