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 status of knowledge and performance on Chinese Heart Failure Diagnosis and Treatment Guideline (2014 version) in general practitioners of Shanghai Pudong communities.Methods The survey was conducted from April to June in 2014 with a self-designed questionnaire.Total 390 general practitioners (GPs) in Pudong New Area were selected by cluster sampling method.The contents of questionnaire included:diagnosis and differential diagnosis,drug therapy,non drug therapy of chronic heart failure.Result Total 385 questionnaires were retrieved with a response rate of 98.7％ (385/390).The results showed that in aspect of diagnosis and differential diagnosis,373 (96.9％) Gps made the diagnosis based on history and physical examination,171 (44.4％)Gps never used BNP or NTPro-BNP tests,280 (72.7％)GPs did not know how to identify systolic or diastolic heart failure,86 (22.3％)Gps made the differential diagnosis according to the EF value.In aspects of drug therapy,the rate of beta blockers use was 10％-30％ in 284 (73.8％) Gps,149 (38.7％) Gps did not use beta blockers because of not knowing the contraindications,289 (75.1％) Gps used a maximum dose of betaloc for 25-50 mg,no one used 101-200 mg,242 (62.9％)Gps did not know the target dose of betaloc,the rate of ACEI/ARB use was 10％-30％ in 330 (85.7％) Gps,258 (67.0％) Gps would increase the dose but not knowing the target dose.The main reason for not using the target dose of Betaloc and ACEI/ARB was not knowing the dose.In aspect of non-drug therapy:240 (62.3％)Gps never heard of cardiac resynchronization therapy (CRT) and 271 (70.4％)Gps never heard of implantable cardioverter defibrillator (ICD).The senior rank GPs grasped the guideline much better than Gps with primary and intermediate professional ranks.Conclusion General practitioners in community health centers should further study the guideline of heart failure,particularly need to strengthen the knowledge and ability of drug therapy.

Objective To analyze the therapeutic effect ofShengji-Yuhong ointment in the treatment of patients with pressure ulcer.Methods 86 patients of pressure ulcer were randomly divided into a control group and an observation group, with 43 cases in each. After debridement, the wound was covered with vaseline gauze in the control group, whileShengji-Yuhong ointment in the treatment group. 10 days constituted 1 course of treatment, and both groups were treated for 3 courses. The blood supply of the whole blood viscosity, plasma viscosity, erythrocyte aggregation index detection; white blood cell count (WBC), erythrocyte sedimentation rate (ESR), and C reactive protein (CRP) were observed in order to observe the control condition of the patients with wound infection.Results The total effective rate was 95.3% (41/43) and 74.4% (32/43) in the observation group and control group respectively, with significant difference between two groups (χ2=5.800,P=0.016). After treatment, the whole blood viscosity (high-shea) (4.06 ± 1.38 mPa?svs. 4.74 ± 1.62 mPa?s,t=2.095), the whole blood viscosity (medium-shea) (3.71 ± 1.22 mPa?svs. 4.34 ± 1.41 mPa?s,t =2.216), blood reduction viscosity (1.13 ± 0.22 mPa?svs.1.44 ± 0.51 mPa?s,t=3.660), the whole blood viscosity (medium-shea) (4.16 ± 0.48 mPa?svs. 4.51 ± 0.89 mPa?s,t=2.270) obviously compared with group before treatment decreased (P<0.05). The patients in the observation group in the whole blood viscosity (medium-shea) (3.71 ± 1.22 mPa?svs. 4.16 ± 0.48 mPa?s,t=2.251), and blood reduction viscosity (1.13 ± 0.22 mPa?svs. 1.32 + 0.31 mPa?s,t=3.278) in the observation group were  obvious better than the control group (P<0.05). After the treatment the WBC, CRP, ESR in the observation group were decreased significantly than the control group (t=5.947, 7.198, 12.064,P<0.01).ConclusionShengji-Yuhong ointment can effectively control the PU infection in the wound, improve wound tissue under the blood circulation, and promote wound healing.

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.

Background It is well known that sclera remodeling occurs during axial elongation in myopia under the control of growth hormone or its downstream effectors.The role of transforming growth factor-β (TGF-β) in myopia has been determined in previous studies.Bone morphogenetic protein (BMP) is one of members of the TGF-β superfamily,but if it plays an important role in the genesis and development of myopia is not completely clear.Objective This study was to identify the presence of BMPs in normal guinea pigs sclera and investigate the change of BMPs in the sclera in form-deprivation myopia (FDM) of guinea pigs.Methods Thirty young guinea pigs were randomized into normal control group and experimental group using table of random number.FDM models were established by occluding unilateral eyes of guinea pigs with a translucent lens for 14 days in the experimental group,and the fellow eyes served as the controls.Diopter of all eyes was tested by retinoscopy optometry,and ocular axial length was measured by A-sonography before and after modeling.Posterior sclera tissue of the animals was obtained on 14 days,and the relative expression level of BMPs mRNA and protein were assayed by reverse transcription PCR (RT-PCR) and Western blot.The use and care of the animals complied with ARVO Statement.Results On 14 days after occluding of unilateral eyes,the refraction diopter of the experimental group was (-0.48±0.51) D,and that of the fellow eyes was (3.22 ±0.34) D,showing a significant difference between them (t =-12.814,P =0.000).Also,a significant difference in the diopter was seen between the experimental group and normal control group ([-0.48±0.51]D vs.[2.97±0.70]D,t =-11.878,P=0.000).Axial length was (8.30 ± 0.05) mm in the experimental group,(8.11 ±0.06) mm in the fellow eyes and (8.06±0.06) mm in the normal control group,showing a significant increase in the experimental group compared with the fellow eyes and normal control group (t =7.230,P =0.000 ; t =9.084,P=0.000).The expressions of BMP-2 mRNA,BMP-4 mRNA,BMP-5 mRNA in posterior sclera were detected in the normal guinea pigs.Fourteen days after the induction of myopia,the relative levels of BMP-2 mRNA and BMP-5 mRNA in sclera were 0.41 ± 0.11 and 0.65 ± 0.06 in the experimental eyes,which were significantly lower than 0.62 ± 0.07 and 0.84 ± 0.03 in the fellow eyes with the descent range of 34.48％ and 23.67％ respectively (t=2.838,P=0.017; t=2.524,P=0.028).The relative values of BMP-2 protein and BMP-5 protein were 0.44±0.06 and 0.70±0.05 in the experimental eyes,and those of the fellow eyes were 0.61±0.05 and 0.82±0.03,showing significant decline in the experimental eyes with the lowing range of 23.42％ and 15.21％,respectively (t =2.465,P =0.030;t =2.445,P=0.031).No significant differences were found in the expression of BMP-4 mRNA and protein in posterior sclera between the experimental eyes and the normal control eyes (mRNA:t =0.704,P=0.460;protein:t=0.987,P=0.365).Conclusions The expressions of the BMP-2 and BMP-5 in sclera down-regulate significantly in FDM eyes,which suggest that BMP-2 and BMP-5 participate in sclera remodeling during myopia induction.

This study is to establish the fingerprint for Phyllanthus emblica and their tannin parts from different habitats by HPLC for its quality control. The determination was carried out on a Diamonsil C18 (4.6 mm x 250 mm, 5 microm) column, with methanol-0.2% glacial acetic acid as mobile phase with gradient elution at a flow rate of 1 mL x min(-1). The temperature was maintained at 30 degrees C and the detected wavelength is 260 nm, Thirteen chromatographic peaks were extracted as the common peaks of the fingerprint of P. emblica, and eleven as the common peaks of P. emblica tannin parts, and five peaks were identified by comparing with referent samples. The fingerprints of 8 samples were compared and classified by similarity evaluation, cluster analysis and principal component analysis (PCA). The similarity degrees of eight P. emblica were between 0.763 and 0.993, while tannin parts were between 0.903 and 0.991. All the samples of P. emblica and their tannin parts were classified into 3 categories. The method was so highly reproducible, simple and reliable that it could provide basis for quality control and evaluation of P. emblica from different habitats.
