Objective To observe the relationship of the Janus kinase-signal transducers and activator of transcription pathway and neurogenesis in the lateral ventricle subventricular zone(SVZ) and choroid plexus of neonatal rats with periventricular leukomalacia(PVL).Methods PVL models were established by right common carotid artery ligation followed by 4 h 60 mL/L oxygen exposure in 2-day-rat;the neonatal rats performed a sham operation,without hypoxia-ischemia were used as control group.The rats were sacrificed at 0 h,3 h,6 h,12 h,1 d,3 d and 7 d after hypoxic-ischemic(HI),and brain tissues were collected,immunohistochemistry was used to detect the expression of P-STAT3 and Nestin in the subventricular zone and choroid plexus.Results Very low expressions of P-STAT3 and Nestin were observed in lateral ventricle SVZ and choroid plexus in control group.The expression levels of P-STAT3 and Nestin increased significantly after HI,peaked at 1 d and 3 d separately,and remained at a higher level at 7 d after HI,demonstrating significant differences at each time point compared with those in control group(Pa

Objective To investigate the toxic effect of nona-ferroso-ferric oxide(Nano-Fe_3O_4),nano-silicon dioxide(Nano- SiO_2)and single walled carbon nanotubes(SWCNTs)on the lung and mechanism in rats.Methods Fourty-nine Wistar rats were randomly divided into 7 groups,the control group,low and high dose groups of three nanomaterials.The rats were exposed by intratracheal instillation once two days for 5 weeks,and then killed by abdominal aorta bloodletting.The pathology of lung,lactate dehydrogenase(LDH),total antioxidant capacity(T-AOC),superoxide dismutase(SOD),malondialdehyde(MDA),interleukin-1(IL- l),interleukin-6(IL-6)and tumor necrosis factor-?(TNF-?)in bronchoalveolar lavage fluid(BALF)were determined.Results The fibrous tubercle and the matrix inflammation of lung tissue was found in the experimental groups.The activities of T-AOC and SOD decreased while IL-6 concentration increased significantly in the experimental groups(P

Objective:To summarize the drug repercussion data in outpatient pharmacy and analyze the reasons to provide sugges-tions for the improvement. Methods: The information was collected from the hospital information system ( HIS) during January 1, 2013 and December 31, 2015, including drug name, category, quantity, amount, reasons for drug repercussion and the other statisti-cal data. Results:During the three years, the number of prescription drugs, amount of money and varieties of drug repercussion were increased. The most common reasons for drug repercussion were the other reasons, withdrawn by doctors and the request of patients. The sum of drug repercussion was positively correlated with the drug price and the amount of drug repercussion. Conclusion:The op-tion simplicity for drug repercussion in HIS is the main reason for drug repercussion bythe other reasons. The occurrence of drug re-percussion should be intervened by such methods as gradually improving the HIS, establishing intervention measures, enhancing the professional quality of pharmacists and so on.

We isolated polyA~+ mRNA direcdy from tumor tissue of ovarian carcinoma using Oligotex~(TM) Direct mRNA Kit (QIAGEN) to synthesize the first and second strand cDNA. The ds-cDNA termini were blunted with pfu DNA poly-rnerase. The blunted cDNAs were added EcoR I adaptor, and then were digested by Xho I . Small cDNA molecules(

Objective To correctly analyze the positive results of electrocardiogram treadmill exercise test (TET) and improve the level of diagnosis of CHD Methods Two hundred and fifty eight patients with chest pain underwent TET and CAG; the case history and different clinical parameters were collected (1) Clinical data of the true positive group and the pseudo positive group were compared and underwent a statistic analysis (2) Clinical data of the female positive group were compared and underwent a statistic analysis Results The number of females in the pseudo positive group was larger than in the true positive group;The number of patients with typical chest pain, hyperlipidemic history, history of smoking, family history of CHD was smaller than in the true positive group;In the pseudo positive group,the changes of ST segment were mainly in Ⅱ, Ⅲ and aVF The number of extent of changes of more than 0 2 mV and with angina induced during exertion in pseudo positive group was smaller than in true positive group In females, under 60 years, the number of ST segment changes of resting ECG and left ventricular hypertrophy was larger in pseudo positive group than in true positive group The difference was significant Conclusion The factors including sex, typical chest pain,risk factors of CHD, the location and extent of ECG changes and angina induced following exertion should be combined to analyze the positive results of TET

Objective To explore the value of neutiophil gelatinase-associated lipocalin ( NGAL) taken from blood and urine samples in early diagnosis of acute kidney injury ( AKI) after heart valves replacement surgeries. Meth-ods A total of 56 patients received heart valves replacement surgeries were selected prospectively in this study. NGAL from blood and urine samples and serum creatinine ( Scr) were tested among them at different moments. AKI and non-AKI groups were divided based on Scr levels and the value of NGAL taken from blood and urine sam-ples was estimated in early diagnosis of AKI with receiver operating characteristic curve ( ROC) . Results 16 AKIs were observed among all of them. The peak value of Scr in AKI group was shown between 12 and 24 hours after surgeries, while blood-NGAL was seen high significantly (P<0.05) since 2 hours after surgeries, peak value at 4 hours, for urine-NGAL, peak value was seen at 2 hours. The area of ROC of blood-NGAL 4 hours and urine-NGAL 2 hours after surgeries for AKI diagnosis were 0.891 and 0.934, respectively. The better sensitivity and specificity were shown in both threshold set as 50 μg/L and 110 μg/L. Conclusion Blood-NGAL and urine-NGAL can be used as early diagnostic markers of AKI after heart valves replacement surgeries, whose change is significantly earli-er than that of Scr.

Objective To discuss the clinicd effect of using nebulised budesonide to treat neonatal laryneal edema caused by mechanical ventilation.Methods 43 newborns with mechanical ventilation were included in this study and divided into two groups:The Observational group(23 newborns)were treated with nebulised budesonide right before excubation once and three times after that,and the control group(20 newborns)were treated with dexamethasone once right before excubation and nebulised adrenine after that for three times.Comparisons were made between two groups about dismissing time of wheeze or hoarseness,tachypnea,PaO2 and PaCO2.Results Observational group:dismissing time of wheeze or hoarseness was(10.26±4.01)hours,dismissing time of tachypnea was(1.63±0.55)days,which was shorter than that of control group[(14.20±5.58)hours/(2.05±0.58)days],P＜0.05).PaO2 and PaCO2 of two groups had no statistical difference(P＞0.05).Conclusion Nebulised budesonide was effective in treatment neonatal laryneal edema caused by mechanical ventilation,using.

Mini-clinical evaluation exercise(Mini-CEX) is a new tool used to evaluate clinical skill of internal residents.Through necessity,operation and practice of Mini-CEX applied in internal residents' clinical teaching,the paper makes it known that Mini-CEX is consistent with six requisitions of resident competence raised by Accreditation Council of Graduate Medical Education (ACGME).It increases medical and directorial quality,and is combined with doctor training abroad.Mini-CEX should be spread in training and examination of internal residents.
