Objective To measure and conduct statistic analysis of normal eyes by Pentacam. Methods Two hundred and twenty-one healthy people (442 eyes) underwent examinations of Pentacam, and they were divided into 5 groups by age: <40 years old group (50 people, 100 eyes), 40-49 years old group (50 people, 100 eyes), 50-59 years old group (50 people, 100 eyes), 60-69 years old group (50 people, 100 eyes) and >70 years old group (21 people, 42 eyes). Results With the increase of age, there were significant differences in chamber volume, chamber angle and anterior chamber depth among age groups (P<0.05). In elder age groups, there were significant differences in these parameters between males and females (P<0.01). Conclusion Anterior segment parameters are significantly correlated with age. After 60 years old, the anterior segment parameters become significantly different with gender.

Objective To investigate the effect of salmeterol/fluticasone (SM/FP) on serum inflammatory factors in the treatment of bronchial asthma in children.Methods 80 children with bronchial asthma from January 2015 to October 2015 in department of pediatrics of first affiliated hospital of Zhejiang Chinese medicine university were selected and randomly divided into two groups.The control group were given routine clinical treatment, the experimental group were treated on the basis of the control group with salmeterol/fluticasone (SM/FP), for 4 weeks.The serum IL-2, IL-4, IFN-α, T-lymphocyte subsets and clinical efficacy between the two groups were compared.Results Compared with control group, the serum levels of IL-2 and IFN-γin experimental group were higher, IL-4 in experimental group was lower ( P <0.05 ); the serum CD3 +T, CD4 +T and CD4 +T /CD8 +T levels in experimental group were higher, the serum CD8 +T was lower than those in control group (P<0.05); the total efficiency of the experimental group (92.5%) was significantly higher than that of control group (75.0%) (P<0.05).Conclusion The salmeterol/fluticasone (SM/FP) has the good efficacy in the treatment of bronchial asthma in children, which could effectively regulate T lymphocyte subsets proportion and the level of cytokines.

Objective To investigate platelet-derived growth factor ( PDGF ) protection on blood flow and mitochondrial function of hemorrhagic shock rats. Methods Ninety-six SD rats were randomly divided into six groups including shock group, lactated ringer's solution (LR) resuscitation group,PDGF treatment groups(1,3. 5,7,15μg/kg). Laster-Doppler and oxygen concentration determination method were applied to observe the protective effect of PDGF treatment on animal survival,blood flow and mitochondrial function in liver and kidney. Re-sults As compared with LR resuscitation group,PDGF treatment increased animal survival rate and also improved blood fiow of liver and kindy,mitochondrial respiration control ration(RCR),of which the group with 3. 5μg/kg had the best result. Conclusion This finding sug-gests that PDGF may be a potential agent to treat acute critical such as hemorrhagic shock.

Objective To observe the estrogenic activity of octylphenol(OP) in vitro and to conduct a preliminary study of its mechanism. Methods The estrogenic activity of OP was detected by cell proliferation test of MCF 7 cells in vitro and the mechanism was preliminarily studied by growth curve analysis, cell cycle analysis, tamoxifen(Tam) antagonistic test and apoptosis detection. Results OP was found to have estrogenic activity to stimulate the proliferation of MCF 7 cells. Cell cycle analysis revealed that the cell proliferation indexes of OP and 17? estradiol(E 2) were higher than those of alcohol. The estrogenic activities of OP and E 2 to stimulate the proliferation of MCR 7 could be antagonized by Tam. Both OP and E 2 could inhibit the cell apoptosis of MCF 7 cells. Conclusion OP possesses estrogenic activity to stimulate the proliferation of MCF 7 cells. The mechanism may be due to binding to the estrogen receptor, which may have effect on cell proliferation and apoptosis.

The uhrastructure and atrial natriuretic peptide(ANP)mRNA in myocardium of streptozotocin-induced diabetic rats were studied along with the effect of rosiglitazone.It was found that the myocardial ultrastructure was demaged in diabetic rats.Rosiglitazone may ameliorate the lesion in myocardium,and lower the ANP mRNA in diabetic rats(1.14?0.05 at 6 weeks and 1.12?0.09 at 10 weeks vs 0.97?0.14,both P

Objective To investigate the clinical pattern,therapeutic principle and influencing factors of interstitial pneumonia in renal allograft recipients.Method The general information,clinical manifestation,treatment and outcomes of 30 recipients with interstitial pneumonia after renal transplantation from Nov.2006 to Dec.2013 were analyzed retrospectively.Result Twenty-nine of 30 patients developed interstitial pneumonia between 2 to 6 months post-transplant.The total course of the pneumonia lasted for 34.9 ± 7.5 days on average.Chest CT scans were used to monitor severity of interstitial pneumonia each week.The mean duration between the onset to the fastigium of pneumonitis was approximately 14.8 ± 1.9 days.The mean duration of the fastigium lasted for 7.3 ±3.6 days,after that the patients usually started to recover.Deteriorated chest CT scan findings and long terms of the fastigium usually indicated poor outcomes.The mean duration of the recovery period was 13.1 ± 3.7 days.After adjusted administration of methylprednisolone,antibiotics,antifungal agents,nutritional support as well as immunosuppressive drugs,23 patients with mild and moderate pneumonia by the chest CT scans were cured and discharged.However,4 of the 7 patients with severe pneumonia by the chest CT scans died.Conclusion The progression of interstitial pneumonia after renal transplantation is characterized by a more consistent regularity.After adjusted administration of methylprednisolone,antibiotics,antifungal agents,nutritional support as well as immunosuppressive drugs,renal allograft recipients with interstitial pneumonia could obtain a good therapeutic effect without over-treatment.

OBJECTIVETo reveal the transmembrane signal pathway participating in regulating neuron functions of treating Alzheimer's disease (AD) by acupuncture.

METHODSSAMP8 mice was used for AD animal model. The effect of acupuncture method for qi benefiting, blood regulating, health supporting, and root strengthening on the amount and varieties of transmembrane signal proteins from hippocampal lipid rafts in SAMP8 mice was detected using HPLC MS/MS proteomics method.

RESULTSCompared with the control group, acupuncture increased 39 transmembrane signal proteins from hippocampal lipid rafts in SAMP8 mice, of them, 14 belonged to ionophorous protein, 8 to G protein, 8 to transmembrane signal receptor, and 9 to kinase protein. Totally 3 main cell signal pathways were involved, including G-protein-coupled receptors signal, enzyme linked receptor signal, and ion-channel mediated signal. Compared with the sham-acupuncture group, acupuncture resulted in significant increase of kinase signal protein amount. From the aspect of functions, they were dominant in regulating synapse functions relevant to cytoskeleton and secreting neurotransmitters.

CONCLUSIONThe cell biological mechanism for treating AD by acupuncture might be achieved by improving synapse functions and promoting the secretion of neurotransmitters through transmembrane signal transduction, thus improving cognitive function of AD patients.

OBJECTIVETo study the relationship between copper and organic components, total flavonoids of Astragalus (TFA), total saponins of Astragalus (TSA) and total polysaccharide of Astragalus (TPA).

METHODTFA, TSA and TPA were extracted from Astragalus roots using different organic solvents, and determined by colorimetry. The concentration of copper in extracts was determined by graphite furnace atomic absorption spectrometry (GFAAS).

RESULTCopper was found in TFA, TPA and TSA, and its concentration in TFA and TPA was higher; the content of copper was correlated significantly to that of TFA and TPA (r1(2) = 0.754 8, F1 = 57.202, P < 0.01 and r2(2) = 0.499, F2 = 21.906, P < 0.01), while not to that of TSA ( r3(2) = 0.0026, F3 = 0.041, P > 0.1).

CONCLUSIONCorrelation analysis could reveal the relationship of copper with organic components in Astragalus roots; contents and structure characteristics of organic components might be important factors influencing the distribution of copper in Astragalus roots.
