OBJECTIVETo observe the effects of electroacupuncture (EA) with branch-foundation acupoint combination on the indices regarding pituitary-target gland axis in aging rats with yang deficiency, so as to explore its regulating mechanism on aging rats with yang deficiency.

METHODSForty healthy Sprague-Dawley female rats were randomly divided into a normal control group, a model group, an EA group and an EA control group, 10 rats in each group. Except the normal control group, the rats in the rest 3 groups were all treated with subcutaneous injection of D-galactose for 40 d, followed by intramuscular injection of hydrocortisone for 7 d to establish aging model with yang deficiency. After the successful establishment of model, the EA group was treated with EA at "Guanyuan" (CV 4), "Housanli" (ST 36) and "Baihui "(GV 20) while the EA control group was treated with EA at "Zhongji" (CV 3) "Yinlingquan" (SP 9) and "Yintang" (GV 29); the rats in the normal control group and model group were immobilized and fixed during the same time period. The treatments were given 6 times per week totally for 4 weeks. With radiation immunity analysis method, the 8 biological indices of pituitary-target gland axis, including thyroid-stimulating hormone (TSH), triiodothyronine (T3), tetraiodothyronine-4 (T4), adrenocorticotropic hormone (ACTH), corticosterone (CORT), estradiol (E2), luteinizing hormone (LH) and follicle-stimulating hormone (FSH) were detected to observe the changes of their content.

RESULTSCompared with the normal control group, the serum level of TSH, T3, T4 and E2 were reduced in the model group (P<0.05, P< 0.01) while those of ACTH, CORT, FSH and LH were increased (P<0.05, P<0.01). Compared with the model group, the serum level of TSH, T3, T4 and E2 were increased in the EA group (P<0.05, P<0.01) while those of ACTH, CORT, FSH and LH were significantly reduced (P<0.05, P<0.01). Compared with the EA control group, the content of TSH was increased in the EA group without statistical significance (P>0.05), that of T3, T4 and E2 was increased (all P<0.05) and that of ACTH, CORT, FSH and LH was significantly reduced (all P<0.05).

CONCLUSIONThe electroacupuncture with branch-foundation acupoint combination has benign regulating effects on the key hormones of pituitary-target gland axis, which could effectively improve the dysfunction of pituitary-target gland axis that is caused by aging with yang deficiency; the efficacy of electroacupuncture with branch-foundation acupoint combination is superior to that of adjacent control acupoint combination.

Objective: To learn the awareness of the Three Level Social-psychological Service in Zhejiang Province and its influencing factors, so as to provide the basis for promoting the construction of social-psychological service system. Methods: The counties (cities, districts) in Zhejiang Province were divided into three levels: high, medium and low, according to economic development. The residents are selected by multistage stratified random sampling method. A questionnaire survey was conducted to collect the general information of residents and their awareness of the Three Level Social-psychological Service.The influencing factors for the awareness were analyzed by multivariate logistic regression model. Results : Of 7 114 questionnaires sent out, 6 577 valid ones were recovered, with the response rate of 92.45%. The overall awareness rates of the Three Level Social-psychological Service and service sites was 63.02% and 59.91%, respectively. The multivariate logistic regression analysis showed that the age of 40-<50 years ( OR=1.376, 95%CI: 1.077-1.758 ), permanent residence ( OR=1.474, 95%CI: 1.319-1.647 ), being the national pilots ( OR=1.200, 95%CI: 1.079-1.334 ) and having the experience of seeking mental health services before 2018 (OR=1.323, 95%CI: 1.191-1.469) were the influencing factors for the awareness of the Three Level Social-psychological Service; under 50 years old ( OR: 0.610-0.768, 95%CI: 0.423-0.991 ), permanent residence ( OR=1.571, 95%CI: 1.407-1.755 ), being the national pilots ( OR=1.368, 95%CI: 1.232-1.519 ) and having the experience of seeking mental health services before 2018 ( OR=0.733, 95%CI: 0.661-0.812 ) were the influencing factors for the awareness of the Three Level Social-psychological Service sites. Conclusions It is necessary to improve the awareness of the Three Level Social-psychological Service among Zhejiang residents. Age, permanent residence, being the national pilots, seeking mental health service experience before 2018 are associated with the awareness of the Three Level Social-psychological Service.

Objective To determine whether the novel surface-anchored protein SasX promotes aggregation of S.aureus and adherence of S.aureus to human nasal epithelial cells.Methods MRSA ST-239 HS770 sasX gene mutant ( HS770 △sasX) and complement [ HS770 △sasX (pRBsasX) ] were gotten by gene knock-out and complement methods.The aggregation ability of S.aureus was observed through microscope.By adherence assay which was used for detection of the adherence ability of wild type and mutant to human nasal epithelial cells and blocking experiments which detected the ability of the purified recombinant SasX protein in blocking the adherence of S.aureus to human nasal epithelial cells,we investigated the influence SasX on colonization of S.aureus.Results Compared to wild type,HS770△sasX showed a reduction in cell aggregation,while the complement had no difference with wild type in aggregation. HS770 △sasX showed a significant reduction of adherence to human nasal epithelial cells compared to wild type ( P＜0.01 ),and the complement showed a very clear increasement of adherence to human nasal epithelial cells compared to wild type(P＜0.01 ).Preincubation of nasal epithelial cells with the purified recombinant SasX protein inhibited S.aureus binding significantly.Conclusion SasX had an influence in aggregation of S.aureus and its adherence to human nasal epithelial cells.By acquiring sasX,S.aureus colonized more easily to the susceptible sites of the host,and thus caused infection.

Objective Cerebral small vessel disease is closely related to kidney disease .Chronic kidney disease ( CKD) may increase the risk of hemorrhage stroke .However, its impact on hemorrhage-prone small vessel disease represented by cerebral microb-leeds( CMBs) remains unclear .The purpose of this study was to investigate the relationship of CKD with the presence and location of CMBs in patients with acute lacunar stroke . Method Consecutive patients with acute lacunar stroke within 7 days from onset were enrolled retrospectively from January 2014 to July 2016 and scanned by gradient-echo T2*-weighted imaging (GRE-T2*WI).Their demographic, clinical, laboratory and imaging data were collected .Estimate glomerular filtration rate (eGFR) was calculated individu-ally by the following chronic kidney disease epidemiology collaboration (CKD-EPI) equation for the Asian population .CKD was defined as the level of eGFR<60 mL/min/1.73 m2. Results Finally, 308 patients (mean age:65.79±8.67 years; median NHISS:3(2-5);42.2%Female) with lacunar ischemic stroke were enrolled in the final analysis .Among these patients, CMBs were present in 116 patients ( 37.7%) and CKD in 62 patients ( 20.1%) .Patients were divided into CKD group and normal group according to GFR level . The result of univariate analysis showed that patients with CKD had higher prevalence of diabetes ( P=0.014) and higher degrees of CMBs (P=0.001) compared with normal group.CMBs were refined by its location .The result of multivariable analysis showed that CMBs in deep brain [ OR=7.61, 95%CI 4.18-16.55, P=0.001] were sig-nificantly associated with CKD incidence , while no significant rela-tionship was found in CKD incidence and CMBs in the lobe and mixed location of brain . Conclusion The CKD incidence in patients with acute lacunar stroke is in dependent relationship with CMBs in deep brain and without significant correlation with CMBs in the lobe and mixed location of brain .
