The opening rate, information update and menu of official WeChat in 11 Hangzhou municipal public hospitals were analyzed in order to understand their running, which showed that of the 11 public hospitals that opened their official WeChat,36. 36% opened their service account and 63. 64% opened their subscription ac-count. The information update frequency of WeChat varied and the online service function needed to be further deepened. Suggestions were put forward for the WeChat running in hospitals, such as normalizing its information push, deepening its online service, diversifying its communication between physicians and patients, and intensifying its popularization.

Hepatocellular carcinoma (HCC) is one of the most common malignant tumor with increasing incidence worldwid.Most of patients with HCC are diagnosed at a late stage.Threrfore,the prognosis of HCC patients is generally poor with a 5-year survival rate of 20% if withoutoperration. Screening strategies including α-fetoprotein (AFP) and ultrasound every 6 months in patients with liver cirrhosis,the major risk factor for HCC development, have been recommended to detect HCC at earlier stages amenable to effective treatment strateges.AFP, however,is a marker with poor sensitivity and specificity and the ultrasound is highly dependent on the operator's experience.Apart from AFP, lens culinaris agglutinin-reactive AFP and des-gamma carbexyprothrombin and several other biomarkers(e.g., glypican-3,human hepatocyte growth factor,and insulin-like growth factor) have been proposed as markers for HCC detection.In addition,with recently employed techniques,such as gene-expressing microarrays and proteomics,it is to be expected that new HCC-specific markers will become available in the near future.For all such proposed markers,however,the clinical usefulness has to be carefully evaluated and validated.

Objective:We try to examine the hypothesis that perceptual reversal is function of frontoparietal cortex. Methods:We employed block design in functional MRI, extracted event signal of endogenous reversal of Necker cube and compared with that of exogenous reversal. Results:Functional MRI revealed that spatial varieties were significant in bilateral superior and middle frontal lobe. Conclusion:Perceptual reversal may be the function of frontal cortex.

The latest advances on target therapies of cancer were presented on the 44th Annual Meeting of American Society of Clinical Oncology(ASCO)in 2008.One of the most important results was the outstanding efficacy of Cetuximab in Metastatic Colorectal Cancer fIncao patients with k-ras"wild-type".Besides,detection of k-ras statuswouldmakeitpossibleforthetailoredtargettherapy of mCRC.Itwasestimatedthat k-ras gene status would become a predictive molecular marker for Cetuximab treatment in mCRC.

Objective To investigate the effects of Xinnaoxuemianning combined with statins on carotid atherosclerotic plaque in patients with cerebral infarction. Methods 180 cerebral infarction patients were divided into the observation group (90cases) and the control group (90cases) by random number table method. The control group was given atorvastatin calcium tablets and the observation group was given additionally Xinnaoxuemianning. The changes and prognosis of carotid atherosclerotic plaques were evaluated before and after treatment, and the incidence of adverse reactions was counted. Results There were no differences in the carotid atherosclerotic plaque, TCM syndrome score and neurological deficit severity between the two groups before treatment. After treatment, the above indexes were significantly improved, and the increasing degree of the observation group was better than that of the control group. The incidence rate of adverse reactions was lower in the observation group than that in the control group (5.56％ vs.13.33％) (P<0.05). Conclusion Xinnaoxuemianning can reduce the carotid atherosclerotic plaque area and correct the unstable plaques in patients with cerebral infarction.

Dr.WU Liang-cun applys constitution doctrine of TCM in treating geriatric oncology patients.According to the classification of constitutions and the features of geriatric oncology’s pathogenesis,Dr.WU Liang-cun advocates the principle of comprehensive treatment and stage treatment.There are different rating in different fuzhenquxie period basis on the patient’s condition of zhen-xie and xu-shi.Dr.WU Liang-cun always pays attention to applying wenshen pharmacy in his prescription.

Objective To study the relationships between serum matrix metalloproteinase-2 (MMP-2) and tissue inhibitor of matrix metal]oproteinase-2 (TIMP-2) with bone metabolic markers and bone mineral density (BMD) in postmenopausal Chinese women.Methods In this study,192 postmenopausal Chinese females aged 48-65 were selected.Serum MMP-2,TIMP-2,bone alkaline phosphatase (BAP),osteocalcin,bone cross-linked C-telopeptides of typeⅠcollagen (CTx) and urine bone cross-linked N-telopeptides of typeⅠcollagen (NTx) were measured by ELISA.And the ratio of MMP-2/TIMP-2 was calculated.BMD was measured by dual energy X- ray abserptiometry.According to the criteria of WHO,these women were assigned to 3 groups : the normal,the low BMD and the osteoporosis groups.Results (1) Serum MMP-2 level was significantly higher in postmenopausal women with osteoporosis (1388?121)?g/L than that in age-matched normal controls (1126?141)?g/L (P0.05).(2) Notable negative relations were found between MMP-2,ratio of MMP-2/TIMP-2 with BMD of lumbar spine and Ward's triangle,serum BAP and osteocalcin (all P0.05).(3) In osteoporosis women,notable negative correlations between MMP-2,ratio of MMP-2/TIMP-2 with BMD of lumbar spine,femoral neck and Ward's triangle,serum BAP and osteocalcin were found (all P

AIM: To quantitatively detect the expression level of transforming growth factor-β1 (TGF-β1) and transforming growth factor-β2 (TGF-β2) genes in the retina of normal rat in order to determine the expression difference of TGF-β1 and TGF-β2 in retina.METHODS: The total RNA was isolated from which the first strand of cDNA was prepared. The mRNA levels of TGF-β1 and TGF-β2 were detected quantitatively by real time polymerase chain reaction (PCR).RESULTS: The mRNA levels of TGF-β1 and TGF-β2 were 0.0008±0.0003 and 0.0378±0.009, respectively. Expression of TGF-β2 was obviously higher than that of TGF-β1 in rat retina with statistical significance (t=12.37, P<0.001). The ratio of TGF-β2/TG-β1 was 55.00±26.61.CONCLUSION: QRT-PCR could specifically and accurately detect gene expression level in rat retina. In retina the TGF-β2 gene was expressed more abundantly than TGF-β1. It is suggested that TGF-β2 play an important role in retina diseases.

AIM: To quantitatively investigate transforming growth factor-β type Ⅰ receptor (TβRⅠ) and transforming growth factor-β type Ⅱ receptor (TβRⅡ) gene expressions in rat retina.METHODS: Sprague-Dawley rats were chosen in this research. Gene expression was detected quantitatively by reverse transcription polymerase chain reaction (RT-PCR) analysis. RESULTS: The expression level of TβRⅠ and TβRⅡ were 0.00034±0.00013 and 0.0001±0.00005, respectively. The expression level of TβRⅠ was obviously higher than that of TβRⅡ in the rat retina with statistical significance (P<0.01). The ratio of TβRⅠ/TβRⅡ was 3.9±1.7.CONCLUSION: Real time quantitative RT-PCR is an effective method to detect differential expression genes in retina. The change of TβRⅠ/TβRⅡ expression may play an important role in the pathogenesis of retinopathy, which could be further investigated in its significance in the development of proliferation retinopathy.
