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 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.

Background The injury or surgery of cornea cause the proliferation of corneal stromal cells and scar formation.Recent research showed that cureumin can obviously reduce the degree of fibrosis of tissue.But if curcumm play inhibitory effect on corneal keratocytes fibrosis is rarely reported.Objecttve This studv was to investigate the effect of curcumin on the transformation of corneal keratocytes into fibroblasts in vitro and further explore the antifibrotic effect of curcumin on corneal keratocytes.Methods The murine corneal keratocytes from 150 BALB/c mice were isolated and primary culture in DMEM culture medium containing 10% fetal bovine serum and then divided into blank control group(inducer group,CG),low-dose group(CG+7.5 mg/L curcumin),mediumdose group(CG+10.0 mg/L curcumin),high-dose group(CG+12.5 mg/L curcumin),non-inducer group.Seven days following intervention,the expression of cell markers such as keratocan,aldehyde dehydrogenase(ALDH),decorin and fibronectin-1 in keratocytes were analyzed by RT-PCR.The effect of curcumin on cultured murine corneal keratocytes proliferation was evaluated by MTS technique.The expression of fibronectin-1 in murine cornea was investigated by immunofluorescence assay.Results The primarily cultured keratocytes showed tlIe fusiform-like shape with the abundant cytoplasm and big nuclei.In the presence of curcumin,the mRNA levels of keratocan and ALDH were down-regulated and those of CD90 and decorin were up-regulated,showing the significantly differences with the increase of dose(P<0.05),but the expression pf fibronectin-i was not obviously changed with the alteration of dose of curcumin. MTS showed that the inhibitory rates of curcumin on keratocytes in 10.0 mg/L and 2. 5 mg/L groups were enhanced in comparison with 7.5 mg/L group, showing statistically significant difference among three groups( F = 956.00, P<0.05). The expression of fibronectin-1 was found in the corneal keratocytes with the red fluorescence in stroma. Conclusion Curcumin can inhibit the fibrosis of corneal keratoeytes in a dose-dependent manner. These results offer a preliminary theoretical basis for the application of curcumin in controlling corneal scar formation during wound healing.

BackgroundPterygia is a clinical common disease.A lot of surgical methods are developed to decrease the recurrence rate.Resent years,the application of fibrin glue is receiving more and more attention.Objective This study was to explore the effects of fibrin glue in decreasing inflammatory irritation and its mechanism. Methods Pterygia models were created in 12 clean rabbits by exsection of limbal tissue and topical administration of 1.25％ diluted hydrochloric acid,and then the conjunctival autograft surgery was performed in the experimental rabbits.The conjunctival flap was sutured in the left eyes,and the conjunctival wound was closed using fibrin glue in the right eyes.The operation duration for each group was documented and compared.The irritation sign was examined under the slit lamp in all the rabbits 1 week and 4 weeks respectively.The expressions of vascular endothelial growth factor (VFGF) and basic fibroblast growth factor (bFGF) proteins in the conjunctiva tissue were detected by immunochemistry,and the expressions of VFGF mRNA and bFGF mRNA in the conjunctival tissue were determined by reverse transcription polymerase chain reaction (RT-PCR).Results The operative duration was (21.3±0.2) minutes in suture group and( 10.1 ±0.1 )minutes in the fibrin glue group with a significant difference between two groups( t =102.242,P＜0.05 ).From 1 week through 4 weeks,the hyperemiain degree was obviously slight in fibrin glue group compared with suture group.Immunochemistry showed that VEGF and bFGF proteins were expressed mainly in the cytoplasm of conjunctival epithelium layer.The positive response intensity was weaker in the fibrin glue group than in suture group 1 week and 4 weeks after operation.RT-PCR revealed that the expression level of VEGF mRNA was significantly lower in fibrin glue group than in suture group,and the VEGF mRNA was gradually decreased with the time lapse ( Fgroup =174.443,P =0.000 ; Ftime =231.459,P =0.000 ).The similar outcomes were found in the expression of bFGF mRNA(Fgroup=41.727,P=0.000;Ftime=55.417,P=0.000). ConclusionsThe use of fibringluecanshortentheoperationdurationandreducepostoperationinflammatoryreaction.The downregulation of VEGF and bFGF in tissue is the possible mechanism of remitting irritation sign,which allows a reduce of the recurrence rate of pterygia.
