Objective To investigate the influence of systematic health education on the disease cogni-tion and behavior of treatment compliance in patients with infectious diseases. Methods Patiens with infec-tious diseases in our department were divided into the control group(142 patients) and the experimental group (136 patients). The control group received common health education, the experimental group was given addi-tional knowledge education about infectious disease based upon routine education. The two groups were inves-tigated before and after intervention by adopting self-designed investigation scale.The cognition rate of disease and the rate of behavior of treatment compliance were compared by χ2 test. Results The cognition rate of disease and the rate of behavior of treatment compliance in the experimental group were higher than those of the control group. Conclusions Systematic health education can not only increase degree of disease cogni-tion but also improve behavior of treatment comphanee in patients with infectious diseases.

Objective To evaluate diagnostic value of head upright tilt testing (HUTT) on orthostatic hypotension (OH) in patients with senile hypertension,and explore its efficacy and safety.Methods One hundred and sixty-six patients with senile hypertension were selected,and the patients were divided into 2 groups according to HUTT:experiment group (completed HUTT,86 cases) and control group (unfinished HUTT,80 cases).The blood pressure change was observed.The detection rate of OH and incidence of unexpected event were compared between 2 groups.Results The detection rate of OH in experiment group was 31.4％ (27/86),in control group was 17.5％ (14/80),and there was statistical difference (P ＜ 0.05).The incidence of unexpected event in experiment group was 0,in control group was 6.2％ (5/80),including 3 patients with dizziness amaurosis,unstable presyncope symptoms and fall,and 2 cases with syncope and sudden fall.There was statistical difference in incidence of unexpected event between 2 groups (P ＜ 0.05).Conclusions The use of HUTT in patients with senile hypertension can significantly improve the detection rate of OH,but also significantly reduce the incidence of unexpected event.The method is safe,effective,worthy of clinical promotion.

Objective By investigating the effects of AT1 and ERK2 signaling pathway in CHF,to study the effect of Guanxin-Shutong capsule on AT1,ERK2 expression in rats with chronic heart failure (CHF).Methods The CHF rat models were setup by coronary artery ligation,exhausting swimming and reducing feeding.Divided CHF rat methods into a model group,a lisinopril group,Qi-benefiting with Chinese medicine group,blood activating with Chinese medicine group,Qi benefiting and blood activating with Chinese medicine group(QBBA group) and Guanxin-Shutong capsule group.Rats without left coronary artery ligation were set for sham operated group.Real-time quantitative PCR technique and immunohistochemical method were adopted to detect AT1,ERK2 changes of CHF rats.Results AT1,ERK2 expression increased obviously in the model group compared with the sham operated group,and differences were statistically significant (P＜0.01).After treatment,AT1,ERK2 expression reduced significantly in QBBA group and Guanxin-Shutong capsule group than the lisinopril group.(P＞0.05).And therapeutic effect of Guanxin-Shutong capsule group was much better than other Chinese medicine treated group (P＜0.01).Conclusion Guanxin-Shutong capsule would achieve the goal of treating chronic heart failure By inhibiting the expression of AT1 and ERK2 in organizations,and inhibiting or reversing ventricular remodeling process.

The samples of experimental and control groups were obtained by 1 ∶ 1 matching method and divided into development (242 pairs) and sign (156 pairs) groups.Through a 10-month group and case type intervention,Gesell test was performed for 5 zone development quotients of large motor,fine motor,adaptability,speech and personal-social to determinate the effectiveness of interventions.Before intervention,t values of the development group were 1.07,1.42,0.78,0.62 and 1.67 while those of sign group-1.48,-1.96,1.82,1.78 and-1.73 respectively.The inter-group comparison of various developmental quotient differences had no statistical significance (P ＞ 0.05).After intervention,t values of the development group were 9.85,8.92,3.57,11.21 and 9.30 for inter-group comparison and-31.65,-36.94,-46.26,-37.56 and-49.85 for intra-group comparison.The results of sign group were 10.91,9.61,10.75,12.01 and 14.36 for inter-group comparison and-23.20,-31.75,-44.94,-33.58 and-54.58 for intra-group comparison.Between intra-group and inter-group,the comparison of the developmental quotient differences had statistical significance (P ＜ 0.01).In two experimental groups,the post-intervention developmental quotients in 5 zones are better than those pre-intervention levels.It shows that preventive intervention of infant mental health is effective.

The rats were assigned to blank control group, classical induction group, and drynaria total flavonoid group. Whole bone marrow culture method was applied to isolate and purify rats bone mesenchymal stem cells (BMSCs). Akaline phosphatase activity, calcium nodes, TGF-β1 and BMP-2 secretion in the process of bone mesenchymal stem cells osteogenic differentiation were detected. The results showed that compared to the blank group and classical group, drynaria total flavonoid promoted osteogenic differentiation accompanied with increased TGF-β1 and BMP-2 secretion (all P＜0. 05). Drynaria total flavonoid may promote osteogenic differentiation of BMSCs via upregulating TGF-β1 and BMP-2 expressions, and play an active role in the treatment of osteoporosis.

Objective To explore the febrile response and placental pathological inflammation of pregnant rats exposed to intrauterine infection in late gestation.Methods Pregnant Sprague-Dawley rats at gestational day 18 were randomly divided into control group and intrauterine-infected group with six rats in each.The intrauterine-infected group was intraperitoneally injected with 350 μ g/kg lipopolysaccharide to establish a rat model of intrauterine infection,while the control group was injected with sterile saline of the same dose.Core temperature was measured every 1 h after intraperitoneal injection of lipopolysaccharide or saline for 8 h.At gestational day 19,after anesthesia,the placentas were taken and stained with HE.The expression levels of tumor necrosis factor-α,interleukin-6,and interleukin-1β in the placenta were determined by enzyme linked immunosorbent assay.Student t test was used for statistical analysis.Results (1) There was no temperature difference between the two groups before experimental treatment (P ＞ 0.05).Core temperature was increased 1 h after the lipopolysaccharide injection,reaching (37.67 ±0.08) ℃.The increase of temperature was significant compared with the control group [(37.13 ± 0.08) ℃,t=10.178,P ＜ 0.01].Fever was lowered 2 h later and the rats became hypothermic with body temperature below 37 ℃ in the intrauterine-infected group.The body temperature in the intrauterine-infected group after 2-6 h was (37.70 ± 0.10),(37.23 ± 0.05),(36.57 ± 0.06),(36.60 ± 0.10) and (36.57 ± 0.08) ℃,respectively,compared with the control group [(36.83 ±0.12),(36.63 ± 0.12),(36.71 ± 0.07),(36.87±0.12),and (36.77±0.08) ℃,respectively],the differences being all statistically significant (t=11.402,11.163,-4.025,-4.000 and-4.243,all P ＜ 0.01).(2) HE staining revealed large amounts of neutrophils infiltration,vascular enlargement and congestion in the placenta of the intrauterine-infected rats.No inflammatory cell infiltration was observed in the control placentas.(3) The expression levels of proinflammatory cytokine tumor necrosis factor-α [(0.62 ± 0.02) ng/g],interleukin-6 [(66.12 ± 5.11) ng/g],and interleukin-1β [(7.09± 1.23) ng/g] in the intrauterine-infected group were higher than those in the control group [(0.27±0.01),(16.71 ±1.55) and (2.86 ± 0.38) ng/g,respectively].The differences were all statistically significant (t=-26.608,-18.749 and-5.714,all P ＜ 0.01).Conclusion After exposure to lipopolysaccharide in late gestation,pregnant rats show significant inflammatory response in the placenta,with suppression of febrile response and presence of hypothermia.

Objective To investigate the expressions of insulin receptor substrate-1 (IRS-1) and insulin receptor sub-strate-2 (IRS-2) in adipocytes during catch-up growth in neonatal rats with intrauterine growth restriction (IUGR) and their correlations with the insulin resistance. Methods Sprague-Dawley rats (clean grade) were randomly divided into control group and food-restricted group after fertilization. Food-restricted group were received about 30%of food amount consumed in control group every day through the whole pregnant period to establish IUGR animal model, and were fed increased amount of breast-milk from postnatal day 1 to 21 to establish the period of catch-up growth in IUGR animal model (IUGR-CG). Fasting serum glu-cose, insulin and triglyceride were measured in blood from heart ventricles of 4-week old SD rats and insulin resistance index was calculated. Pre-adipocytes and mature adipocytes were obtained from SD rats at different age (1-week, 3-week, 5-week and 7-week old) and the former were induced to differentiate toward mature adipocytes. The levels of IRS-1, IRS-2 in the two kinds of mature adipocytes were detected by Real-Time PCR and Western blot. Results The expression levels of IRS-1, IRS-2 mRNA in mature adipocytes of IUGR-CG rats were signiifcantly lower than those of IUGR rats at 5-weeks and 7-weeks old (P<0.05) while the ex-pression levels of IRS-1, IRS-2 mRNA in differentiated adipocytes of IUGR-CG rats were signiifcantly lower than those of IUGR rats at 5-weeks old (P<0.05). The expression levels of IRS-1, IRS-2 protein in two kinds of adipocytes (mature and differentiated adipocytes) of IUGR-CG rats were signiifcantly lower than those of IUGR rats from postpartum week 1 through 7 (P<0.05). Conclusions IRS-1 and IRS-2 expression levels are downregulated in adipocytes during catch-up growth of IUGR rats, which may be closely related with insulin resistance.

Objective To discuss the clinical features and treatment of isovaleric academia (IVA) patients,and to gain more comprehensive understanding of isovaleryl-CoA dehydrogenase(IVD) mutation in 2 siblings in order to raise awareness to prevent the occurrence of IVA.Methods The clinical history and laboratory test of 2 cases of children with IVA were carried out.The exons and neighboring introns of IVD gene of the whole family were PCR-amplified for DNA sequencing.The literature review of IVA in China was also conducted.Results Organic acid analysis of urine by GC/MS for both siblings showed extremely elevated concentrations of isovaleric glycine.For the older sibling,an acute episode of IVA caused severe metabolic stress and eventually death in the neonatal period.However,the disease was well-controlled for the younger sibling due to timely treatment and follow-up care for 2 years.The DNA sequencing of the IVD gene in the family revealed a novel c.1016G ＞ A(C339Y) heterozygous mutation in mother and both of the siblings.No IVD mutation was detected in father or in any of the 50 cases of healthy controls.According to literature review,15 cases of IVA were reported in recent 15 years in China,including neonatal onset (11 cases),acute episode (12 cases),odor of sweaty feet (12 cases),pancytopenia (9 cases),hyperammonemia (5 cases),hypocalcemia (6 cases),and 6 cases of death were reported.Additionally,5 cases that received treatment of BCAA-free formula milk showed positive outcome.However,only 2 cases were followed up for more than 2 years.Conclusions Two new IVA patients carrying c.1016G ＞ A(C339Y) mutation were reported in China.The mutation may lead to conformational change and functional deficient of the IVD protein.It is also necessary to point out that using direct DNA sequencing can not identify all patients with IVA due to limitations of this technology,and thus clinicians should be aware of the possibility of genetic misdiagnosis.Moreover,there is a trend of increasing IVA in China in recent years.

Objective To explore the effect of community comprehensive intervention on stroke-prevention-related knowledge, belief and behavior of hypertensive patients. Methods The community-based comprehensive interventions were done to 77 hypertensive patients, with the measures including archives establishment, hypertension-phased management, regular follow-up and multi-mode health education. The stroke-prevention-related knowledge, belief and behavior of them were assessed by the stroke-preventing knowledge questionnaire (SPKQ), champion′s health belief model scale (CHBMS) and (stroke-prevention behavior questionnaire,SPBQ) before and after the intervention. Results Their knowledge on daily-life and pre-stroke symptoms and part of their behaviors (health duty, physical exercises and stress management after the intervention were superior, as compared to the pre-intervention (P<0.05). There were no significant differences in other stroke-related knowledge and behaviors and health belief in comparison of the pre-and post-intervention (P>0.05). Conclusion The community-based intervention can improve parts of stroke prevention knowledge and health behavior among hypertensive patients. The intervention needs to be modified based on ecological models of health promotion and health belief model.
