Objective To explore the effect of TLR2 on collagen Ⅰ(colⅠ) in adipose tissue of high-fat-diet induced obese mice.Methods Male C57bl/6J mice and TLR2 knockout mice were divided into groups according to high fat diet or normal chow.Total collagen, TLR2, colⅠ, MMP1, MMP2, TIMP1, colⅠα1 mRNA and colⅠα2 mRNA in adipose tissue were measured at the end of the experiments.Results Total collagen, TLR2, colⅠ, MMP2, TIMP1, colⅠα1 mRNA, and colⅠα2 mRNA in adipose tissue increased while MMP1 in adipose tissue decreased in mice with high fat diet.Decreased levels of total collagen, colⅠ, MMP2, TIMP1, colⅠα1 mRNA and colⅠα2 mRNA in adipose tissue were detected in TLR2 gene knockout mice with high fat diet.However, there was an increased level of MMP1 in TLR2 gene knockout mice with high fat diet.Conclusion In high-fat-diet induced obese mice, deposition of colⅠ in adipose tissue seems to be alleviated by TLR2 gene knockout via MMP1 and TIMP1.

Under the influence of Chinese medicine scientization, Chengjiang Acupuncture School, which was originated in the Republic of China (1912 - 1949), has also undergone a series of scientific practice. The Chengjiang School established scientific research, education and medical organizations such as the Research Society of China Acupuncture-Moxibustion, China Acupuncture-Moxibustion School, Training School of China Acupuncture-Moxibustion and Sanatorium of Acupuncture-Moxibustion. Zhenjiu Zazhi (Journal of Acupuncture-Moxibustion) was established, and monographs and textbooks such as Zhongguo Zhenjiu Zhiliaoxue (Therapeutics of Chinese Acupuncture-Moxibustion) and Zhongguo Zhenjiuxue Jiangyi (Lectures on Chinese Acupuncture-Moxibustion) were published. Meanwhile, based on clinical practice, large members of acupuncture personnel with scientific literacy emerged. Therefore, it is held that the scientization of Chengjiang School has performed a profound influence on the development of modern acupuncture-moxibustion.

OBJECTIVETo observe the effect of Shen warming Pi strengthening method on expressions of serum T cell subsets (C045+%, C03+%, and C04 +/COB+) in diarrhea-predominant irritable bowel syndrome (IBS-0) rats. Methods An IBS-0 rat model was established referring to AL-Chaer's modeling method combined with tail clamp and intragastric administration of sanna leaf. After modeling 30 SO rats were randomly divided into 6 groups according to random digit table, i.e., the model group, the high, middle, low dose Wenshen Jianpi Recipe (WJR) groups, and the Sishen Pill control group, 6 in each group. A normal control group consisting of 6 SO rats were also set up. Rats in high, middle, low dose WJ R groups were administered by gastrogavage with boil-free WJ R at the daily dose of 3. 100, 1. 550, 0. 775 g/kg, respectively. Rats in the Sis hen Pill control group were administered by gastrogavage with boil-free Sis hen Pill at the daily dose of 0. 736 g/kg. Equal volume of normal saline was given by gastrogavage to rats in the model group and the normal control group. All medication lasted for 2 successive weeks. Rats' general state, expressions of T cell subsets (CD45+%, CD3+%, and CD4+ /CDB+) changes were observed.

RESULTSCompared with the normal control group, expressions of CD45+% and CD3+% increased, but CD4+ /CDB+ decreased with statistical difference (P < 0. 05). Compared with the model group, expressions of CD45+% and CD3+% decreased, but CD4+ ICDB+ increased with statistical difference in high, middle, low dose WJR groups, and the Sis hen Pill control group (P <0. 05). Compared with the Sis hen Pill control group, there was statistical difference in all indices except CD45+ value in the low dose SWPSM group (P <0. 05). Compared with the low dose WJ R group, the expression of CD3+% decreased in high and middle dose WJR groups, and the Sis hen Pill control group; CD4+ /CD8+ increased in the Sishen Pill control group and the high dose SWPSM group (all P < 0. 05).

CONCLUSIONSWJR showed better treatment effect. The mechanism of Shen warming Pi strengthening method might be achieved by regulating expressions of CD45+% and CD3+%, and CD4+ /CD8+ ratios.

Objective To study the protective effect of Irisin in doxorubicin(Dox)induced-Cardiomyopathy and its possible mechanism.Methods AC 16 cells were used to construct Dox injury model and divided into control group(AC 16 cells were cultured with complete medium),Irisin group(AC16 cells were treated with 10 ng·L-1 Irisin for 24 h),Dox group(AC 16 cells were treated with 4 μmol·L-1 Dox for 24 h),Dox+Irisin group(AC 16 cells were pretreated with 10 ng·L-1 Irisin for 2 h,and then treated with 4 pmol·L-1 Dox for 24 h).Cell counting kit-8(CCK-8),terminal deoxynucleotidyl transferase-mediated nick end labeling(TUNEL)and lactate dehydrogenase(LDH)were used to detect the proliferation,apoptosis and mortality of AC 16 cells.Western blot was used to detect the expression levels of nuclear factor-κB(NF-κB)signaling pathway and apoptotic factors B-cell lymphoma-2(Bcl-2),Bcl-2-associated X protein(Bax)and caspase-9 protein.Mito-Tracker Red CMXRos probe was used to detect mitochondrial membrane potential.Results In the contrl group,Irisin group,Dox group,Dox+Irisin group,the rate of apoptosis were(0.97±0.09)％,0,(42.80±6.70)％,(11.74±1.79)％;the expression of Bax protein were 0.85±0.01,0.36±0.02,1.15±0.07,0.37±0.11;the expression of caspase-9 protein were 0.52±0.02,0.59±0.03,1.11±0.02,0.67±0.08;the expression of Bcl-2 protein were 1.01±0.04,1.05±0.25,0.43±0.02 and 0.99±0.30;the probability of mitochondrial damage were(0.02±0.01)％,(0.5±0.15)％,(38.6±2.39)％,(1.58±0.54)％.The difference of the above indexes between the contrl group and the Dox group were statistically significant(all P＜0.05);the difference between Dox group and Dox+Irisin group were statisically significant(all P＜0.05).Conclusion Irisin could reduce the expression level of Bax,caspase-9,p-NF-κB,and p-mTOR caused by Dox,increase the expression level of Bcl-2,ameliorate the myocardial damage caused by Dox,and reduce cardiotoxicity.

AIM: The study was undertaken to investigate the effort of Dexamethasone (DEX) on cultured rabbit corneal epithelial (RCE) cells and rabbit corneal epithelial wound healing.METHODS: For the in vitro experiments, primary cultures of RCE cells were used. DEX in different concentrations was added to cultured RCE cells. The effects were measured with tetrazolium salt (MTT)method and flow cytometry. For the in vivo wound-healing experiments, a central corneal deepithelialization was created and were treated with 0.1g/L DEX eyedrop randomly explain how randomly. Epithelial wound healing was evaluated clinically and analyzed histopathologically using light microscopy along with immunohistochemical staning and electronic microscopy.RESULTS: Less than 0.1g/L DEX didn't influence survival rate in cell culture conditions by MTT assay. Flow cytometric studies revealed that 0.1g/L DFX had no effect on cellular growth phase in cultured rabbit corneal epithelial cells. The mean time of the epithelial healing was significantly shorter in the DEX-treated group than in the control group at 24h. There were strong proliferative-cell-nuclear-antigen(PCNA) expressions in newly generated epithelial cells of both groups. The Dex-treated group had a more regular architecture of stromal lamella and significantly less inflammatory response than the control group under electronic microscopy.CONCLUSION: Less than 0.1g/L DEX had no inhibiting effect on cultured rabbit corneal epithelial cell growth.0.1g/L DEX eye drops can effectively promote epithelial growth and reduce inflammatory response, which may have useful clinical application at the early stage of corneal wound healing process.

To investigate the effects of Losartan,an angiotensinⅡ(AngⅡ)receptor(AT_1) antagonist,on pancreatic stellate cells(PSCs)and its possible mechanisms.Methods (1)PSCs were isolated from pancreatic cancerous samples to test the expressions of AT_1 and collagenⅠafter incubated with AngⅡor/and Losartan.(2)Ninety S-D rats were divided into normal group,control group and treatment group,with 30 rats in each.The rats in control and treatment groups were induced pancreatic fibrosis by injection of 2% trinitrobenenze sulfonic acid(TNBS)into biliopancreatic duct.Rats in treat- ment group were then treated with Losartan by garage daily and rats in control group were only given distilled water.The rats were sacrificed on day 3,7,14,21 and 28,respectively,and pancreas were removed.The histological abnormalities were observed by electron microscope.The mRNAs of trans- forming growth factor?_1(TGF?_1)and procollagenⅠwere detected by reverse transcription-polymerase chain reaction(RT-PCR).The expression of TGF?_1 and?-smooth muscle actin(?-SMA)proteins was assessed by immunohistochemistry and the level of?-SMA protein was quantified by Western blot. Results In vitro,there existed AT_1 expression in PSCs,and Losartan reduced expression of collagenⅠ.Losartan treatment reversed the histological abnormalities observed by electron microscope,com- pared to treatment with distill water.The expression of?-SMA,TGF?_1 and procollagenⅠwere signifi- cantly higher in the control group than those in normal group and were reduced by Losartan to different extent in treatment group.Conclusion AT_1 antagonist can inhibit the activation and the profibrogenic action of PSCs by blocking AT_1 receptor-mediated pathways.

Objective To explore the mode of clinical psychological intervention of operative patients,pmbe into the value of music therapy in clinical application,and slart the new application fields.Methods 60 Datients were divided into the experiment group and the control group.Patients in the two groups accepted the pre-operative psychological intervention 1 d before the operation.Afier the operation.the complex psychological intervention was given to the patients during recovery from general anesthesia in the experiment group.While the patients in the control group were waken only by means of music.The heart rate(HR),pulse oximetry (SpO2),mean arterial pressure(MAP) and the objective indexes of Hamilton Anxiety Scale(HAMA)were assessed between the two groups.Results MAP in the experiment group and the control group were(79.80 4±7.76)mm Hg,(82.33±6.42)mm Hg(1 mm Hg=0.133 kPa),respectively,There was no statistical meaning in MAP and SpO2 between the two groups(P>0.05).HR were(80.76±13.92),(85.82±13.39) times/minute.respectively.The difference of HR had statistical meaning(P<0.05).The anxiety degree (9.78 4±2.32)in the experiment group was obviously poor than that(11.08±2.97)in the control group,and the difference had a statistical meaning(P<0.01).Conclusions The complex psychological intervention is a combination of preoperative psychological intervention,postoperative music awakening,and psychological guidance assisted under the music during the stepwise recovery of consciousness.It provides the whole process,timely,individual and pertinent help and psychological guidance,having active effect in reducing the patients' anxiety degree.

AIMTo study the protective effects of hydroxyethylpuerarin against the injury of astrocytes induced by hydrogen peroxide (H2O2).

METHODSExperiments were performed with cells from passage 4. Plasma membrane integrity was measured by lactate dehydrogenase (LDH) release. The occurrence of apoptosis was measured by flow cytometry. The glutamate uptake of astrocytes was studied with [3H]-glutamate incorporation. Intracellular superoxide dismutase (SOD) activity and malondialdehyde (MDA) level were assessed by automatic biochemistry analyzer.

RESULTSCompared with H2O2 injured group, the occurrence of apoptosis, levels of LDH release and intracellular MDA of astrocytes reduced in hydroxyethylpuerarin pre-treated groups, but the glutamate uptake and intracellular SOD activity of astrocytes increased.

CONCLUSIONHydroxyethylpuerarin could reduce the occurrence of apoptosis and improve neurotrophic function of astrocytes, which may be related with its antioxidant effects during oxidative stress.
