Objective To explore the changes of myocardial enzymes,hepatic function,renal function and 8-iso-prostaglandin F2?(8-iso-PGF2?)in newborn infants with hyperbilirubinemia and their relationships.Methods One hundred and twenty-six neonates who were 2 to 7 days old were selected.Seventy-six cases were hyperbilirubinemia,and according total bilirubin(TB),they were divided into hyper bi-lirubinemia A group(HBE-A)(51 cases,TB 205-341 ?mol/L)and hyperbilirubinemia B group(HBE-B)(25 cases,TB≥342 ?mol/L).Fifty newborn infants with physiologic jaundice were control group(TB

Objective To study the difference of galectin-3 and HBME-1 expression between benign and malignant thvreid nodules and to evaluate their clinical value.Methods Using immunohistochemical SP method,the paraffin-embedded tissues of 30 ewes papillary thyroid carcinoma(PTC)and 30 cases nodular goiter(NG) were examined to deteet the expression of Galectin-3 and HBME-1.Results The rates of positive staining of Galectin-3.HBME-1.Galectin-3 combined with HBME-1 in PTC were 93.3%(28/30),83.3%(25/30)and 100.0%(30/30),respectivdy,were higher than that of NG[20.0%(6/30),6.7%(2/30)and 26.7%(8/30)].There were significant differences between PTC and NG(X2＝32.85,35.65,34.74,all P＜0.01).The sensitivity,specificity,positive predietive value.negative predictive value and accuracy rate of using Galectin-3,HBME-1,Galectin-3 combined with HBME-1 in differentiation NG from FrIE were 93.3%,83.3%,100.0%;80.0%,93.3%,73.3%;82.3%,92.6%,78.9%:92.3%,84.8%,1 00%;86.7%,88.3%,86.7%,respectively.Conclusion Immunohistochemical stains of Galectin-3 and HBME-1 may be used as two lnarkel's for differentiating PTC and NG,it is especially sensitive when the two markers are jointly used.

Objective The objective of digitalized patient records control is to meet some new demands set on patient records control under the new circumstances. Methods A computer system for digitalized patient records control and supporting processing, management and applications setups were established. Results The system put the contents of the patient records into various categories with difierent standards and designed relatively strict means of authorization. It rendered patient records easier to use and their control more strict, making it possible to make general use of the records without access to the original documents. As a result, data loss was avoided, authority over the data was put under control, data sharing was provided, and full and convenient use of data was realized. Conclusion Digitalized patient records control, a form of shaping computer-based patient records before the latter fully comes into being, enhances the efficiency of patient records application and reduces the pressure of paper records storage. It is a practical and effective way of controlling patient records.

Objective To investigate the cavernous nerves innervation from prostate apex to glans penis and the relation between cavernous nerves and surrounding tissues and organs. Methods The urethra and penises of three formalin preserved adult cadavers were removed from prostate apex to glans penis.The sections underwent hematoxylin-eosin staining and Bielschowsky nerve staining.The course and distribution of cavernous nerves and relationship between the cavernous nerves and surrounding tissues and organs was observed microscopically and photographed from prostate apex to glans penis. Results From serial sections we found when nerve fibres run along prostate apex,while surrounding the lateral and dorsal aspects of prostate apex and urethra.from 30'clock to 9 0'clock.Most fibres went through smooth muscle and some of them went through the periphery striated muscle and urogenital diaphragm.The distance to urethra lumen was only 3-5 mm.After the nerve fibres went distally and anteriorly,they accompanied closely with cavernous vein plexus and then went into corpora cavernosa.At the distal end of corpora cavernosa,there were"windows"through which the neurovascular bundles communicated between corpora cavernosa and glans penis just like doors to glans penis. Conclusions When nerve fibres run from prostate apex to urogenital diaphragm,along dorsal lateral aspect of prostate and urethra,there are only 3-5 mm to the urethra lumen,so it is very easy to be injured in traumas or operations.In the urethral bulb fragment,the nerves run anteriorly and laterally.out of the periphary muscle,so the cavernous nerves will not be i~ured when dissect urethra bulb from surrounding muscles.Dissect glans penis from distal end of penis in operation would be avoided in order to protect the cavernous nerves between corpora cavernosa and glans penis.

Objective To compare the effects of ticagrelor and clopidogrel on patients undergoing percutane-ous coronary intervention(PCI)with acute ST elevated myocardial infarction (STEMI).Methods 120 patients with STEMI received PCI within 12h of symptom onset in our hospital were randomly divided into clopidogrel treated group (n=60)and ticagrelor treated group (n=60).Serum was collected before surgery and 36 hours after PCI for ALT, Cr,CK-MB,and MA.Cardiac ultrasound was examined,too.All patients were followed 6 months post-PCI for main adverse cardiovascular and cerebrovascular events (MACCE)and medicine side effect.Results No significantly difference was noted in baseline between the two groups.The level of CK-MB and MA in the ticagrelor treated group [CK-MB(56.5 ±8.3)U/L,MA (45.9 ±6.4)mm[and clopidogrel treated group[CK-MB(74.3 ±9.6)U/L,MA (35.6 ±7.3)mm]were significant difference (CK-MB,P=0.043;MA,P=0.038).The MACCE of patients in ticagrelor treated group were significantly lower than patients in clopidogrel treated group during post-PCI 6 months follow-up(The ratio of angina in ticagrelor group was 1.7%,while in clopidogrel group was 6.7%,P=0.042). Conclusion Ticagrelor is more effective in suppress the function of platelet,decrease MACCE in patients with STE-MI undergoing PCI.

BACKGROUND:The anesthesia process is required strict in establishing rabbit models of ileal neobladder. It is required for cleaning operation field, quick postoperative recovery, and the choice of anesthetics and anesthesia does not influence smooth muscle peristalsis. OBJECTIVE:To compare the anesthetic effects between urethane and chloral hydrate in rabbits with ileal neobladder. METHODS:Eighteen rabbits were randomly assigned to urethane and chloral hydrate groups, and were respectively anesthetized with 20% urethane 5 mL/kg and 10% chloral hydrate 2 mL/kg through the ear vein. Double ureter was dissociated at 1 cm outside original bladder, and 15 cm-intestine obtained from 10 cm of ileocecal junction was implanted so as to establish models of ileal neobladder. RESULTS AND CONCLUSION:Heart rates were significantly lower compared with these before anesthesia in al cases (P≤ 0.05), but no differences were detected between two groups (P > 0.05). Compared with the chloral hydrate group, the maintain time and recovery time were longer and the mortality rate was higher in the urethane group. Above data indicated that chloral hydrate is a safe long-acting anesthetic in establishing rabbit models of ileal neobladder.

Objective To assess the feasibility of heterogeneous acellular dermal matrix(ADM)seeded with adipose derived stem cells(ADSC)for urethroplasty in a rabbit model.Methods ADSC were isolated from a rabbit and expanded in vitro,then identified by flow cytometry.We seeded ADSC onto the ADM and made it into tissue-engineered urethra.12 male rabbits were removed 1 cm urethra and divided into experiment group and control group.There were 6 rabbits in each group.Reconstructed urethra with tissueengineered urethra was used in experiment group,while unseeded ADM were used in control group.Urethrography was performed at 6 months after surgery.The animals were scarified at 3 and 6 months after surgery and the repaired urethra were harvested.H&E staining and immunohistochemical staining were performed with cytokeratin AE1/AE3 and smooth muscle desmin makers.Results The morphology of isolated ADSC was with long spindle cross-links,and had multicentral growth.Flow cytometry showed that the ADSC expressed CD166,CD105,CD90 and CD44,but not expressed CD45 and CD13.The cells could growth well on the ADM and showed good biocompatibility with it.All animals could void normally,urethrography showed there was no significant stenosis.3 months after surgery,the experiment group appeared regenerated smooth muscle but not in the control group,both groups did not regenerate urothelium.At 6 months urothelium and smooth muscle cells could be observed in the experiment group,but only the smooth muscle was evident in the control group.Conclusions By applying tissue engineering methods,we can seed the ADSC onto the heterogeneous ADM and make it into tissue-engineered urethra,which can help improve the reconstructive effect of urethra.

Objective:To investigate the internet game addiction disorder and influential factors in the middle school students of Guangzhou.Methods:A total of 900 middle school students of Guangzhou selected by cluster sampling were investigated with unified questionnaires.Results:Of the middle school students tested,4.9%were diagnosed internet game addiction.There were remarkable differences of the addiction to network game in demography variable,such as age, educational background of father and family economic situation.Between online game addicts and non-addicts,there were significant discrepancies in social support,subjective support,use of support,self-identity,self investment today,and parent-child conflict.Gender,subjective support,parent-child conflict,self investment now,educational background of father and family economic situation entered the regression model.Conclusion:Internet game addiction is closely associated with social support,parent-child relationship,and self-identity.
