Objective To investigate the value of acoustic radiation force impulse (ARFI) on evaluating the renal tubular atrophy and interstitial fibrosis of IgA nephropathy(IgAN).Methods 117 patients diagnosed with IgAN,and 80 normal cases were examined with conventional ultrasonography and ARFI,recording the shear wave velocities(SWV),the hemodynamics and the renal biopsy results to quantify the elastic changes of renal cortex,with the aim of assessing AFRI's advantages on early diagnosing the impair of kidney.Results The SWV value of renal cortex,renal medulla of IgAN group were smaller than that of normal group (P ＜0.05),while the collective system SWV value had no difference(P ＞0.05).According to the ROC curve,the cut-off value of SWV in renal cortex was 2.7 cm/s.The accuracy of the diagnosis was 71 ％,which was better than RI (61.9％).The SWV value of the renal cortex decreased with the different stage of 1,2,3,4,but stage 5 was larger than stage 4.The degree of renal tubular atrophy and interstitial fibrosis(T) can be classified by the SWV of renal cortex,and the SWV of T2 was larger than T1 (P ＜0.05).Conclusions By quantifying the elastic change of kidney,ARFI technology is able to distinguish the degree of renal tubular atrophy and interstitial fibrosis,diagnose renal impairment early and judge the clinical stages.Furthermore the sensitivity,specificity,accuracy of it are superior to hemodynamic.

Objective To evaluate the value of p504S,CK34?E12 and p63 immunostaining for the diagnosis of benign and malignant lesions of the prostate. Methods Expression of p504S、CK34?E12 and p63 in benign and malignant lesions of the prostate was observed by microwave SP immunohistochemical method. Results Continuous positive expression of CK34?E12 and p63 was found in the acini and ducts of most benign prostatic hyperplasia, and few cases showed interrupted expression, but p504S staining presented negative reaction; Interrupted expression of CK34?E12 and p63 was found in high prostatic intraepithelial neoplasia cases, and was weekly positive or negative for p504S; CK34?E12 and p63 staining was positive in five atypical adenomatous hyperplasia cases, one case presented focally positive reaction by p504S; CK34?E12 and p63 staining was negative in forty prostatic carcinoma, but positive by p504S;The gleason histologic grading of prostate carcinoma was negatively related to expression of p504S. Conclusion Combined detection of p504S、CK34?E12 and p63 can be most helpful for diagnosis of prostate carcinoma, especially in needle biopsy specimen.

Objective The purpose of this study was to access the efficacy of Venlafaxine and Reboxitine on treatment of depressive patients who had not responded to selective serotonin reuptake inhibitors for eight weeks. Methods 117 cases depressive patients who had not responded to selective serotonin reuptake inhibitors for eight weeks were divided into three Venlafaxine group(n =41),Reboxitine group(n =39),Original medicine group(n =37) by randomly and were treated by corresponding drugs for 8 weeks. The therapeutic response and safety were evaluated by scale of HAMD and TESS at before and after treatment the end of 1,2,4,8 week. Results The score of HAMD in Venlafaxine and Reboxitine groups were significantly lower than Original medicine group at the end of 4,8 weeks after treatment and the score of HAMD in Venlafaxine group were significantly lower than Reboxitine group at the end of 8 weeks after treatment. The score of HAMD in Venlafaxine and Original medicine groups were marked descendanter than before treatment from after treatment second weekend(P <0.01),while reboxitine group did not marked descent until the 4th weekend after treatment. The reduce score of factors in cognition,retardition and desperation of Venlafaxine and Reboxitine groups were significantly higher than Original medicine group at the end of treatment. The curative effect of Venlafaxine group were supper than Original medicine group. The side reaction of three groups were not difference. Conclusions There are obviously curative effect using Venlafaxine to treat the depressive patients who had not responded to selective serotonin reuptake inhibitors. The time of initial effect in Venlafaxine were rapider than Reboxitine group.

Objective To establish the system of statistic index of health examination information. Methods The items of health examination were screened, the valuable indexes for guiding the health condition were selected and standardized, and then the system of statistic index of health examination information was constructed. Results The 42 items for male clients and 74 items for female clients were selected as the statistic index of health examination information system. Standardized the statistic index with international classification of diseases system, including the criterion of name, diagnosis and data collection.The standard statistical tables were constituted. Conclusions Health examination information system can be statistically added up by standard index system.

OBJECTIVEThe demographic characteristics of acupuncture outpatient in China is investigated so as to provide clinical evidence for the establishment of acupuncture indication.

METHODSClinical epidemiological table was adopted to do cluster multistage random sampling in 36 hospitals of 31 provinces (municipalities and autonomous regions) in 2008. The composition ratios of all indices were analyzed with SPSS 13.0 software. And trend analysis was carried out on the patient's demographic characteristics and the age distribution of clinical indications.

RESULTSIn the year 2008, 31 858 cases of out patients from 36 hospitals of 6 administrative regions were collected. There were totally 14 411 male patients (45.2%) and 17 447 (54.8%) female. The gender ratio of male and female was 82: 100. The average age of the patients was (50.6 +/- 17.7) years old. The number of patients over 45 years old was more obvious than groups of other ages (P<0.05). Age differences can be found in those 6 regions (P<0.05). Clinical symptoms varied according to different ages of the patients. Different characteristics of age distribution of acupuncture indications were held to exist (P=0.000).

CONCLUSIONAt the present, differences of gender, age and region can be found in out patients of acupuncture clinic. And the result shows that the number of female patients is more than male, with a large proportion of patients over 45 years old. Differences of age distribution characteristics of acupuncture indications still exist, which is considered to have the relation with the dominate indications of acupuncture and aging of the population.

Objective To investigate the effects of autoantibodies (β1-AA) against second extra-cellular loop of the β1-adrenergic receptor (β1-AR-ECⅡ) in sera of patients with dilated cardiomyopathy (DCM) on proliferation of rat CD4+T lymphocytes.Methods β1-AA in the sera of patients with DCM was purified by affinity chromatography .CD4+T lymphocytes were isolated by immunomagnetic microbeads from peripheral blood mononuclear cells of rats and its positive rate was detected by flow cytometry .CCK-8 meth-od was used to detect the proliferation of CD 4+T lymphocytes and flow cytometry was performed to measure the ratio of CD4+/CD8+T lymphocyte .Results The purity of isolated rat CD 4+T lymphocytes by immu-nomagnetic microbeads reached 97.7%.The proliferation of CD4+T lymphocytes stimulated by CD3/CD28 was inhibited by β1-AA in a concentration-dependent manner .However , IgG antibodies extracted from sera of healthy controls did not suppress lymphocyte proliferation (P>0.05).The suppression effect of β1-AA was inhibited after binding to antigenic peptides corresponding to β1-AR-ECⅡ and was completely blocked by metoprolol, a specific antagonist of β1-adrenergic receptor (β1-AR).In addition,β1-AA had no effects on the ratio of CD4+/CD8+T lymphocyte .Conclusion β1-AA isolated from DCM patients suppresses the pro-liferation of CD4+T lymphocytes through β1-AR pathway , which indicates that β1-AA can directly reduce the number of T lymphocytes and impair the function of T lymphocytes , resulting in immune system disorders and the development of DCM .

The intraspecies quorum sensing system of Streptococcus mutans is involved with com genes family.ComE is a kind of response regulator and act as a promoter to the quorum sensing genes.S.mutans comE mutant strain IFD140?comE was constructed using the inframe-deletion system via twice homologous recombination.In current genetic studies of S.mutans,insertion duplication and allelic exchange mutagenesis techniques routinely create polar effects to downstream genes.In-frame deletions are essentially free of these polar effects because the mutation does not introduce any genetic markers.By PCR,sequencing and RT-PCR,it was confirmed that IFD140?comE has only 717bp deleted within the comE gene and the transcription of the downstream gene comD was not interfered.The research of the morphological characteristics indicated that IFD140?comE formed clumps and cells accumulated at the bottom of the glass tubes and light-microscopic observations displayed that the mutant strain formed significantly longer chains compared to those formed by the wild strain.The successfully construction of IFD140?comE lay a foundation for further quorum sensing research.
