Objective To observe the promoting effect of psychotherapy on hypertension patients.Methods100 hypertension patients were randomly divided into the intervention group(52 cases) and control group(48 cases).The intervention group was given drug therapy and psychotherapy while the control group was treated with drug therapy and health education.Blood pressure and scale of Symptom Checklist-90(SCL-90) were used to assess the treatment results.ResultsThere were no significant differences between the two groups in systolic blood pressure(SBP) and diastolic blood pressure(DBP) before the treatment(P>0.05).After interventions,SBP and DBP of the two groups decreased significantly,but the intervention group was more effective than the control group(P<0.001).The intervention group had lower scores of SCL-90 than the control group(P<0.05).ConclusionPsychotherapy can effectively improve the negative moods and mental health of hypertension patients.

This study was aimed to observe the effect ofZi-Bu Pi-Yin Recipe (ZBPYR) on the mRNA expressions of NMDA receptor subunits NR1, NR2A, NR2B in different brain regions of spleen-yin deficiency Alzheimer's Disease (AD) model rats. The levels of NR1, NR2A, NR2B mRNA expressions were detected by using RT-PCR method. The results showed that the levels of NR1, NR2A, NR2B mRNA expressions of AD group and spleen-yin deficiency AD group decreased significantly (P < 0.05). The levels of NR1, NR2A, NR2B mRNA expressions of ZBPYR treatment group increased significantly (P < 0.05). It was concluded that the expression levels of NMDAR mRNA in different brain regions of the ZBPYR treatment group increased significantly, which indicated that ZBPYR may up-regulate the protein expressions of NMDAR by increasing the expression levels of NMDAR mRNA, thereby to play the anti-dementia effect.

Objective To observe the influence of tumor necrosis factor-alpha(TNFα) on skeletal muscle protein catabolism in rats with chronic obstructive pulmonary disease (COPD) and the effects of indomethacin (IND) on it. Methods Duplicated COPD model rats were divided into two groups: the malnutrition group and the normal nutrition group. The malnutrition group were further divided by randomized block design into four groups. Isotonic physiologic saline was administered to group A, the control and the normal nutrition group, and different doses of oral IND were administered to groups B, C, and D weight, concentrations of TNFα, contents of 3-methyl-histidine ( 3- M H ) and tyrosine (Tyr) in the diaphragm and extensor digitorum longus muscle homogenates were measured before and after the intervention. Results Before the intervention, the concentrations of TNFα in the serum of malnutrition groups were all significantly higher than those of normal nutrition group and the control group. After the intervention: (1) The concentrations of TNFα in the serum of the rats of group B, C and D were significantly lower than the group A, especially in group C. The levels of TNFα in serum and body weight of model group rats were negatively correlated ( r = -0. 846, P ＜0. 01 ), as well as the diaphragm and extensor digitorum longus muscle weights ( r = - 0. 778, P ＜ 0. 01; r = - 0. 772, P ＜ 0. 01 ). (2) The levels of 3-methyl-histidine in the diaphragm and extensor digitorum longus muscles of the intervention group C was lower than the COPD normal nutrition group, as well as the intervention groups B and D. The contents of tyrosine in the diaphragm and extensor digitorum longus muscles of the intervention group C was lower than that of the COPD normal nutrition group,as well as the groups B and D. The body weight growth value of the intervention group B were slightly higher than the group A, without significant difference( P ＞ 0. 05 ), while the group C was significantly higher than the group A ( P ＜ 0. 01 ). Conclusions TNFα is involved in the occurrence of COPD malnutrition and skeletal muscle amyotrophy. IND can reduce the TNFα levels in the serum and the catabolic rates of the skeletal muscle proteins in malnutrition rats with COPD, so as to improve partly the skeletal muscle atrophy.

Objective To study the different ultrasonic features in patients of polycystic ovary syndrome (PCOS) with or without obesity based on body mass index (BMI), and to investigate whether certain hormonal factors correlate with ovarian morphology and blood flow, and to discuss the role of ultrasound combined with hormone test in the diagnosis of obese PCOS. Methods One hundred and five women with PCOS were recruited. Patients were divided into two groups according to BMI;obese PCOS group (OB-PCOS, n=32, BMI≥25 kg/m2) and non-obese PCOS (NOB-PCOS, n=73, BMI<25 kg/m2). The ultrasonic parameters of follicle number (FN), ovarian volume (Vol), resistance index (RI) of ovarian stromal blood, RI of uterine artery and serum levels of luteinizing hormone (LH), follicle stimulating hormone (FSH), the ratio of luteinizing hormone and follicle-stimulating hormone (LH/FSH), progesterone (P), estradiol (E2), free testosterone (FT), prolactin (PRL), sex hormoe binding globulin (SHBG), fasting plasma glucose (FPG), fasting insulin (FINS), the extent of insulin resistance and hyperandrogenism (HOMA-IR) were measured and compared. The correlation of the ultrasonic parameters and hormonal factors were analyzed. Results The Vol of OB-PCOS group was significantly higher than NOB-PCOS group [(12.25±4.89) ml vs (10.73±2.30) ml, t=2.20, P < 0.05]. FN and uterine artery RI of OB-PCOS group had a rising trend and RI of ovarian interstitial was on a reducing trend compared with NOB-PCOS group. But the differences were not statistically significant. The levels of FINS and HOMA-IR in OB-PCOS group [(14.82±6.45) mU/L and (3.91±3.30)] were significantly higher than those in NOB-PCOS group [(8.04±4.57) mU/L and (1.64±1.20)] (t=4.87, 3.47, respectively, both P < 0.01). And FSH in NOB-PCOS group was significantly higher than OB-PCOS group [(5.95±1.91) U/L vs (4.65±1.88) U/L, t=-2.77, P<0.01]. In POCS patients, FN was significantly associated with LH/FSH (r=0.35, P<0.01), and FT (r=0.38, P<0.01). Vol was significantly associated with LH/FSH, BMI, HOMA-IR and FPG (r=0.27, P<0.05;r=0.25, P<0.05;r=0.40, P<0.01;r=0.32, P<0.01). RI of ovarian stromal blood flow was significantly associated with SHBG (r=0.28, P<0.05). In OB-POCS group, RI of uterine artery was significantly associated with PRL (r=-0.58, P < 0.05). Vol was significantly associated with HOMA-IR (r=0.47, P < 0.05). In NOB-POCS group, FN was significantly associated with LH/FSH (r=0.33, P<0.05), and FT (r=0. 56, P<0.05). Vol was significantly associated with FT (r=0.31, P < 0.05). Conclusion There are some differences in the ultrasound and endocrine parameters between obese and non-obese PCOS patients, and some correlations exist between them.

This study was aimed to observe the changes of dendritic spine density in different regions of brain among spleen-yindeficiency dementia (SYDD) model rats, in order to investigate the effects ofZi-Bu Pi-Yin Recipe (ZBPYR) on dendritic spines. Spleen-yindeficiency (SYD) rats were modeled by classical method. And incubatedβ-Amyloid 1-40 (Aβ1-40) was injected into the hippocampus of each rat to make SYDD model, which received the administration of ZBPYR. Golgi staining was used to stain dendritic spine in different regions of brain in rat model for the observation of the amount and shape. The results showed that dendritic spine density in different regions of hippocampus and cortex in SYDD group was reduced than that of the SYD group. Compared with the dementia group and the SYDD group, the dendritic spine density in different regions of hippocampus and cortex of the SYDD + ZBPYR group was increased. Compared with the blank control group, the dendritic spine density in different regions of hippocampus and cortex in rats from the dementia group was reduced. It was concluded that there were different degrees of reducing in the dendritic spine density of different brain regions in SYDD group. ZBPYR improved the learning and memory impairment, which might be related to the maintenance of dendritic spine density in different brain regions.

OBJECTIVETo observe the influence of heat shock preconditioning on the expressions of heat shock protein (HSP) 60 and HSP 70 and on the activities of cytochrome oxidase (CCO) and superoxide dismutase (SOD) in mitochondria in gastric mucosa of severely scalded rats, and to investigate its protective mechanism on acute gastric mucosal lesion in rats with severe scald.

METHODSOne hundred and forty-four Wistar rats were randomized into three groups, i. e. scald group ( n = 40, acute gastric mucosal lesion was made after scald, other 8 normal rats without scald were employed as blank control); HS group ( n =40, with heat shock preconditioning 20 h before scald), and other 8 rats preconditioned with heat shock but without scald were employed as experimental control I; actinomycin D group ( n = 40, with intraperitoneal injection of 0. 1 mg/kg actinomycin D 30 min before heat shock preconditioning and other treatment as HS group), and other 8 rats with merely actinomycin D injection were employed as experimental control II. Eight rats in each group were sacrificed and laparotomized at 3, 6, 12, 24 and 48 post-scald hours (PSH) , respectively to determine the index of gastric mucosal lesions (UI ) , the mRNA expressions of HSP70 and protein expression of HSP60 and HSP70, and the changes in the activities of SOD and CCO.

RESULTSUI of the scalded rats increased as the time elapses, reaching the peak (12. 8 +/- 1.9) at 24 PSH. In addition, UI in HS group was significantly lower than that in scald group at each time-point except that at 3 PSH ( P < 0. 05 or 0. 01). The extent of gastric mucosal lesion in rats in actinomycin D group was obviously aggravated compared with that in scald and HS groups ( P <0. 05). The HSP70 mRNA expression in both scald and HS groups was increased at each time-points except for 48PBH, while that in actinomycin D group was increased at 24 PBH and 48PBH. The expressions of HSP70 and HSP60 were greatly increased in HS group compared with those in scald group ( P < 0. 05 or 0. 01) , while those in actinomycin D group were significantly inhibited ( P < 0. 05). The activities of CCO and SOD were gradually decreased in gastric mucosa in scald group, but it was greatly improved by HS preconditioning at 6, 12, 24 PSH ( P < 0. 05 or 0. 01).

CONCLUSIONHeat shock preconditioning is beneficial for the protection of acute gastric mucosal lesion of rats after severe scald, due to increase of HPS60 and HSP70 expression, and increase of CCO and SOD activities in mitochondria.
