Objective To investigate whether the serum adiponectin is related to the atherosclerosis in type 2 diabetes.Methods Thirty three normal control subjects(NC group),66 type 2 diabetes subjects without atherosclerosis(NAS group),and 66 type 2 diabetes subjects with atherosclerosis(AS group) were recruited.The intima media thickness(IMT) of dorsalis pedis artery were measured using B-mode Doppler ultrasonography.Serum adiponectin and other gluco-lipid metabolic indices were determined.Results 1)Compared with NC group and NAS group,the IMT value in AS patients were significantly increased(P

Cardiac muscles of mouse embryos, newborn and suckling mice were used for histological and histochemical studies. This paper presents the observations on the morphogenesis and ultrastructure of cardiac myocytes under electron microscope and on their reactions of nucleic acids (DNA and RNA), glycogen, lipids, succinodehydrogenase (SDH), alkaline and acid phosphatases (AKP and AcP), glucose-6-phosphatase (G-6-Pase) and adenosine triphosphatase (ATPase) under light microscope.The heart of mouse embryo before 12-day, contained numerous polygonal or star-shaped myoblasts which had not yet acquired myofibrils but a few myofilaments. As the myoblast developed, the number of myofilaments increased in number and formed myofibrils, then the cells became myocytes. By the end of embryonic period, all the special elements of myocyte were basically constituted. The myocytes of embryos were rich in RNA granules, and their DNA was deeply stained. Flourishing mitosis appeared only in the early embryonic phase. RNA of adult myocytes was much less than that of embryos. From the early phase of embryos myocytes were full of glycogen but short of lipid droplets. From the day it was born, glycogen decreased apparently but lipid droplets increased rapidly.The reaction of SDH steadily increased in intensity from its early phase to late one. After birth it became more intensive. G-6-pase first appeared in the myocytes of 14 day's embryos. In the fetal period it showed moderate positive reaction, but in the myocytes of suckling muose it appeared negative. The enzyme showed positive reaction again at the age of 2 weeks. The ATPase reaction was found to be weak in the fetal specimens, only appeared in the endothelium of the capillaries. After birth it gradually became intensive and from the 2nd week positive reaction was obvious in adult, it was very vigorous.The above observations showed that the embryonic development and differentiation were gradually completed. Histological and histochemical features of each developmental period showed their individualities, which confirmed the evidence that the cardiac muscle developed not only successively but also by stages, and approached adult's level at 2nd week end after birth.

Objective To investigate the relationship between benign prostatic hyperplasia (BPH) and urine albumin excretion.Methods A total of 258 male inpatients aged 60 to 70 years were enrolled in this study.According to prostate volume (PV) measured by transrectal ultrasonography,patients were divided into BPH group(PV≥20 ml) and NBPH(non benign prostatic hyperplasia) group(PV＜20 ml).Urine albumin and urine creatinine concentrations were measured and urine albumin/creatinine ratio(UACR) was calculated.Fasting blood glucose(FBG) and fasting insulin(FINS) also were measured,insulin resistance index(HOMA-IR) was calculated based on the formula HOMA-IR=ln(FBG × FINS/22.5).The correlation between PV and other indicators were analyzed by Pearson correlation analysis.The risk factors for BPH were analyzed by logistic regression analysis.Results UACR was significantly higher in BPH group than in NBPH group[(163.6± 69.8) mg/g vs.(73.3 ± 55.6) mg/g,t =4.81,P＜ 0.01],and hypertension duration was longer in BPH group than in NBPH group [(9.2±6.6)years vs.(6.0±3.6)years,t=2.27,P＜0.05].The prevalence rate of BPH and PV were increased along with increasing of urine albumin excretion(x2=4.58,F=4.85,respectively,P＜0.05 or 0.01).Prostate volume was positively correlated with UACR,HOMA-IR,hypertension duration,body mass index(r=0.248,0.229,0.183,0.157,respectively,all P ＜ 0.05).Logistic regression analysis indicated that UACR,HOMA-IR and hypertension duration were the risk factors for BPH(OR=16.348,1.040,0.166,respectively,all P ＜0.05).Conclusions BPH is correlated with UACR,which indicates that there is a close relationship between atherosclerosis and BPH.Insulin resistance probably plays an important role in the progression of arteriosclerosis and BPH.

Objective To evaluate the diagnostic and therapeutic status of elderly benign prostatic hyperplasia (BPH).Methods Totally 188 male elderly in outpatient department from January 2010 to March 2012 were enrolled in this study.Medical history was inquired in detail,and prostatic volumes (PV)were measured by abdominal ultrasound,PV≥ 20ml was diagnosed as BPH.Lower urinary tract symptoms (LUTS) was evaluated by international prostate symptom score (IPSS),prostate specific antigen (PSA) was measured.Age≥62 years,PSA≥1.6 μg/L and PV≥31 ml were considered as higher risk of clinical progression of BPH.We investigated the rate of prevalence,awareness and treatment of BPH.PV,IPSS and PSA were compared among different age groups by ANOVA.Logistic regression analysis was made to show the risk factors of BPH.Results Among 188 male elderly,the prevalence rate of BPH was 48.4％,and the total rate of awareness was 41.5％.The rate of awareness resulting from seeing doctor due to LUTS was 10.6％.PV,IPSS and PSA were increased with ageing.Risk factors contributing to BPH were age,hypertension and diabetes.The treatment rate with drugs of 5a-reductase inhibitor was 47.3 ％,however 10 subjects had not been given drugs treatment among 46 patients with higher risk of clinical progression of BPH.Conclusions The prevalence rate of BPH is increased with ageing,the proportion of seeing a doctor with passion is lower because the male elderly have not paid enough attention to LUTS.And doctors have not given drugs intervention to patients with clinical progression BPH in time.We should launch propaganda and education among the elderly patients with hypertension and diabetes and take comprehensive treatment.

OBJECTIVE To investigate the prevalence of extended-spectrum ?-lactamases (ESBLs) and antibiotic resistance in Klebsiella pneumoniae isolates.METHODS ESBLs-producers were detected by CLSI phenotypic confirmatory test and susceptibilities were tested by agar dilution method.RESULTS 41.1% Of isolates were ESBLs producers in those isolates. ESBLs producers were highly resistant to piperacillin,cefazolin,cefuroxime,fluoroquinolones,chloramphenicol,SMZ-TMP and amikacin. The resistant rate to piperacillin-tazobactam,and ceftazidime was 26.3% and 34.2%. None was resistant to imipenem and meropenem in ESBLs producers. Except for carbapenems,the resistant rate to other antimicrobial agents was significantly higher in ESBLs producers than non ESBLs producers.CONCLUSIONS With resistance to most of antimicrobial agents,ESBLs-producers are highly prevalent in K. pneumoniae isolates,more attention should be paid to monitor these strains.

Objective To summarize X-ray,CT finding of mediatinal emphysema in the neonate.Methods The X-ray,CT finding of 16 cases with mediatinal emphysema in the neonate were anolysed retrospectively.Results X-ray finding of 16 cases were:around diaphram with a low density band 13 cases,with spinnaker sign 8 cases,with continous diaphram sign 3 cases,there were only little emphysema in anterior-mediatinal 3 cases,accompany with pneumothorax 5 cases.CT imaging of 3 cases was a low density image in diaphram that was CT value was negative(-500～-900Hu).Conclusion Radiography of chest is the first method about diognosis mediatinal emphysema in the neonate,profile chest is more profit to diagnose little emphysema in anterior-mediatinal,CT can diagnose further clear.

Objective To evaluate the ability of MALDI-TOF MS in identification of the yeast isolated from clinical specimens.Methods 387 strains of yeasts were tested.All the strains were from clinical specimen and identified by VITEK MS and API ID 32C system at the same time.Sequencing of the internal transcribed spacer (ITS) regions of ribosomal DNA was used as the reference method in the analysis of a total of 387 yeast isolates.The accuracy of detected results was analyzed by the X2 test.Results The identification accuracy rates of VITEK MS, API ID 32C were respectively 97.7% and 93.0%.The difference was statistically significant (X2=9.439, P=0.002).There was no statistical significance between MALDI-TOF and ITS sequencing.Conclusion MALDI-TOF is a rapid simple and accurate method which is identified to species level in identification of yeasts.
