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.

To investigate the morphogenetic process of human adenovirus type 41 (HAdV-41), 293TE cells were infected with purified wild-type HAdV-41, and ultrathin sections of infected cells were prepared and observed under a transmission electron microscope. Results showed that HAdV-41 entered host cells mainly through three ways: non-clathrin-coated pit, clathrin-coated pit, and direct penetration of plasma membrane. In addition, cell microvilli might help HAdV-41 enter cells. After entering into cells, HAdV-41 virus particles could be found in vacuoles or lysosomes or be in a free state in cytoplasm. Only free virus particles could be found near nuclear pores (NP), suggesting that the virus needed to escape from lysosomes for effective infection and viral nucleoprotein entered the nucleus through NP. Progeny viruses were as-sembled in the nucleus. Three types of inclusion bodies, which were termed as fibrillous inclusion body, condense inclusion body, and stripped condense inclusion body, were involved in HAdV-41 morphogenesis. In the late phase of viral replication, the membrane integrity of the infected cells was lost and viral particles were released extracellularly. This study reveals the partial process of HAdV-41 morphogenesis and provides more biological information on HAdV-41.

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 .

Objective To evaluate the clinical efficacy and safety of domestic Sirolimus-eluting stents (Firebird) and imported Zotalimus-eluting stents ( Resolute) in the treatment of patients with unprotected left main coronary artery disease ( ULMCA) . Methods We retrospectively enrolled 76 patients with ULMCA treated by percutaneous coronary intervention (PCI) under the guidance of IVUS in our hospital. According to the different stents used in the procedure, the patients were divided into two groups: Domestic Sirolimus-Eluting Stents group (Firebird group, n = 42) and Imported Zotarolimus-Eluting Stents group (Resolute group, n = 34) . We analyzed the baseline characteristics, coronary artery lesion characteristics, stenting strategies and any changes in left ventricular ejection fraction ( LVEF) in both groups and investigated the long-term clinical outcomes. Results There were no significant differences in the baseline characteristics, the SYNTAX scores of the coronary artery lesion and the rate of complete revascularization between the two groups. Compared with that in Firebird group, there were more cases involving the distal left main (79. 4% vs. 45. 2% , P ﹤ 0. 05) and more patients using two stents strategies (29. 4% vs. 7. 1% , P ﹤ 0. 05) in the Resolute group. The change in LVEF post-PCI had no difference between the two groups. The patients were followed up for a mean of (23. 3 ± 10. 7) months. During the follow-up period, the occurrence of MACCE had no significant difference between the two groups. In the Firebird group, there were one sudden cardiac death, one nonfatal myocardial infarction, one stroke and five patients with recurrence of angina pectoris. In the Resolute group there were one sudden cardiac death, one target lesion revascularization and four patients with recurrence of angina pectoris. Conclusions Compared with the imported Zotalimus-Eluting Stents, the domestic Sirolimus-Eluting Stents are safe and effective in the treatment of patients with unprotected left main lesions under the guidance of IVUS. The two kinds of stent showed similar long-term clinical outcomes.

Objective To determine the effect of paired immunoglobulin-like receptor B (PirB) on growth of retinal ganglion cells (RGCs) in vitro.Methods Expression of PirB in RGCs isolated from wild-type C57 BJ/6 mice was measured by immunofluorescence.Real-time PCR and Western blot were performed to detect PirB expressions in RGCs cultured for 1,3,5,7 and 9 days.Primary cultured RGCs were left untreated as controls,transfected with lentiviral-delivered PirB RNAi as Group A,lentiviral-delivered NgR RNAi as Group B,lentiviral-delivered PirB RNAi plus ciliary neurotrophic factor (CNTF) as Group C,lentiviral-delivered NgR plus CNTF as Group D,and only CNTF as Group E.Growth and development of RGCs were evaluated by MTT assay and morphological analysis.Results Immunofluorescence confirmed expression of PirB in RGCs,with its mRNA and protein levels changing from increase at first to decrease later with time,up to peak at days 5 and 7.PirB and NgR were respectively down-regulated in Groups A and B.Viability of RGCs was improved in Group A compared with control group [(40.2 ± 5.3) μm vs (29.1 ± 3.8) μm at day 3 ; (72.2 ± 4.2) μm vs (52.3 ± 8.2) μm at day 5,both P ＜ 0.05].By contrast,no significant difference was found in viability of RGCs among Groups B,D and E when compared to control group (P ＞ 0.05).Growth of RGCs between Groups A and C revealed insignificant difference (P ＞ 0.05).Conclusion Knockdown of PirB is beneficial for the growth of RGCs,suggesting a novel method to treat optic nerve injury.
