Aortic valve calcification (AVC) is a pathological process correlated with multiple disease causes and actively regulated by cardiac valve cells. In this study, porcine aortic valve myofibroblasts cultured in vitro were treated with 50 μg z L(-1) of pathological factor tumor necrosis factor α (TNF-α). Tanshinone II A (TSN) with the concentration of 50 mg x L(-1) and TNF-α were combined in incubating cells for 72 h (3 d) and 120 h (5 d). The Western blotting and Real-time PCR were adopted to detect the changes in smooth muscle α actin (α-SMA), bone morphogenetic protein 2 ( BMP2), alkaline phosphatase (ALP) in cells, and expressions of key effect proteins GSK-3β and β-catenin on Wnt/β-catenin signal pathway. According to the findings, TNF-α can significantly increase the expression of myofibroblasts α-SMA and add the transformation activity to them, with nearly no expression of BMP2, ALP and mRNA in the control group and the TSN group but significant increase in their expressions in the TNF-α group (P < 0.01), which showed osteoblast-like phenotype. Moreover, TNF-α down-regulated the expression of up-streaming regulator GSK-3β and mRNA expression (P < 0. 01) , notably increased the expression of key effect protein β-catenin, but with no significant difference in mRNA with the control group and the TSN group. The result demonstrated that TSN showed a certain inhibitory effect on TNF-α's pathological impact (P < 0.05) in a time-dependent manner. Inflammatory factor TNF-α may promote the transformation of aortic valvular myofibroblasts to osteoblast-like phenotype by activating Wnt/β-catenin signal pathway in aortic valvular myofibroblasts, so as to cause AVC. Tanshinone II A can have a preventive effect in AVC by activating GSK-3β proteins and regulating signal transduction of Wnt/β-catenin signal pathway.

Objective To investigate the changes of sympathovagal balance and the effects of va- gus stimulation on sympathovagal balance in endotoxemia rats.Methods Twenty-four Spragne Dawley rats were randomly divided into four groups.The frequency domain of heart rate variability(HRV)com- ponent was analyzed at 0 min,2 ,4 and 6 hours after intravenous injection of lipopolysaccharide(LPS, 5mg/kg)or physiologic saline,and cervical vagal nerve was stimulated(5mv,2ms,1Hz,5 min lasted, 20 min interval)when LPS or physiologic saline was injected.The levels of Noepinephine(NE)and Ace- tylcholin(ACh)were measured in liver tissues.Results Normalized low frequency(LFnm),hormali- zed high frequency(HFnm),very low frequency(VLF),LF/HF values and liver ACh were significantly increased(P＜0.05)and the level of liver NE was significantly decreased (P＜0.05)after LPS admin- istration.Vagal nerve stimulation markedly increased HFnm but decreased LFnm,VLF,LF/HF values, and the liver ACh also significant increased(P＜0.05 ).Conclusion The results suggest that the ac- tivity of sympathetic and vagal nerve was increased during endotoxemia,but the sympathetic activity was more excitable than that of vagal nerve.Vagal nerve stimulation increased the tone of vagus nerve while the tone of sympathetic nerve was decreased in this study.This may be beneficial for anti-inflammatory activity of vagal nerve.

The two verities of Crgptococcus neoforinans were first observed as well growing with brown color changes on Guizotia abyssinica seed agar(GASA)and caffeic acid commeal agar(CACA.Then,C.neoformans var.neoformans was found in 18/26 pigeon droppings by both two media.C.neoformans var.gattii was not isolated by the two media in 76 Eucalyptus camaldulensis samples.However,an,overgrowth of filamentous fungus was more frequently seen on GASA.Our results suggest that CACA be capable of selevtively isolating C.neoformans with the advantages of less interference fron the overgrowth of filamentous fungi.

AIM:To explore efficacy of the different kinds of artificial tears treatment in patients with xerophthalmia after phacoemulsification combined with intraocular lens implantation.METHODS:Totally 280 patients (280 eyes) with xerophthalmia after operation in our hospital from January 2015 to June 2016 were selected.According to the different treatment methods, they were divided into control group (n=70;treated with tobramycin and dexamethasone eye ointment 3 times per day for 1wk, levofloxacin eye drops 3 times per day for 1wk, pranoprofen eye drops 4 times per day for 1mo), polyacrylic acid group (n=70;besides the treatment of control group, polyacrylic acid was used 4 times per for 1mo), polyethylene glycol group(n=70;besides the treatment of control group, polyethylene glycol was used 4 times per for 1mo) and sodium hyaluronate group (n=70;besides the treatment of control group, sodium hyaluronate was used 4 times per for 1mo).The tear film break up time (BUT), Schirmer Ⅰ test (SⅠt), symptoms of dry eye and corneal staining in four groups were observed.RESULTS:(1) BUT:The BUT of the four groups significantly increased after treatment(P<0.05);that of polyacrylic acid group, polyethylene glycol group, and sodium hyaluronate group was different compared with control group(P<0.05);the BUT in sodium hyaluronate group was significantly higher than the other groups after 2wk of treatment(P<0.05).(2) SⅠt:SⅠt of the four groups significant increased after treatment(P<0.05);that of polyacrylic acid group, polyethylene glycol group, and sodium hyaluronate group was different compared with control group(P<0.05);and the SⅠt in sodium hyaluronate group was significantly higher than other groups (P<0.05).(3) Xeroma score:the scores of dry eye significantly decreased after treatment in the four groups(P<0.05);that of polyacrylic acid group, polyethylene glycol group, and sodium hyaluronate group was different compared with control group(P<0.05);and the scores of the sodium hyaluronate group after 3wk was significantly lower compared with other groups(P<0.05).(4) Corneal staining score:the scores significantly decreased after treatment in the four groups(P<0.05);at 1 and 2wk after treatment the corneal staining score had not statistically different among the four groups (P>0.05);sodium hyaluronate group was significant lower than other groups in corneal staining score at 3wk and 1mo after treatment(P<0.05).CONCLUSION:Artificial tears in the treatment of xerophthalmia after cataract phacoemulsification combined with intraocular lens implantation has better clinical efficacy, which contains sodium hyaluronate may be the better than others.

OBJECTIVETo observe the clinical efficacy of Zengse Pill ( ZSP) on patients with vitiligo of qi-stagnancy and blood-stasis syndrome type (V-QB), and to preliminarily explore its mechanism of action.

METHODSSixty-five V-QB patients, with their diagnosis confirmed by clinical examination, were randomized by digital table method into two groups, with 31 patients in the control group and 34 in the treatment group. Cobamamide (2 tablets) was administered orally to all patients, and Psoralea tincture (a self-formulated preparation) was applied externally thrice a day. In addition, for patients in the treatment group, ZSP was given orally, at 5 pills per dose, 3 times every day. The therapeutic course for both groups was 3 months. Patients were re-examined every half-month, and changes in the skin lesions were observed and recorded. The levels of lymphocyte subsets, serum immune globulin, and complement C3 and C4 in patients were determined before and after the therapeutic course and compared with the corresponding indexes determined in 21 healthy subjects.

RESULTSThe total effective rate in the treatment group was 82.4%, which was markedly higher than that in the control group (54.8%), showing a significant difference (P<0.05). After treatment, CD(4) (+) percentage, CD(4) (+)/CD(8) (+) ratio, and blood levels of C3 and C4 increased, while CD(8) (+) percentage decreased in the treatment group (P<0.05 or P<0.01). All these indexes remained unchanged in the control group, and the respective comparisons between groups showed significant differences (P<0.01).

CONCLUSIONZSP has a definite clinical effect on the treatment of V-QB but with no evident adverse reactions, and it can increase the CD(4) (+) percentage, CD(4) (+)/CD(8) (+) ratio, and the levels of serum C3 and C4, thus regulating the immunity of the organism, which might be one of its mechanisms of action.
