OBJECTIVETo compare the difference in clinical efficacy on post-stroke motor aphasia among the combined therapy of acupoint application of jieyu plaster and acupuncture, simple acupuncture and simple acupoint application of jieyu plaster.

METHODSEighty-six patients of post-stroke motor aphasia were randomized into an acupuncture group (28 cases) , an acupoint application gruop (29 cases) and the combined therapy group (29 cases). In the acupuncture group, acupuncture was applied at the Speech No. 1 area and three-tongue needling points, once a day, 6 times a week. In the acupoint application group, jieyue plaster was applied to Yongquan (KI 1) and Laogong (PC 8), once a day, and the bilateral acupoints were selected alternatively. In the combined therapy group, the therapeutic methods of the first two groups were used in combination. The treatment lasted for 4 weeks in the three groups. The speech function score was observed and compared before and after treatment in the three groups and the efficacy was compared among the three groups.

RESULTSThe total effective rate was 86.2% (25/29) in the combined therapy group, which was better than 67.9% (19/28) in the acupuncture group and 69.0% (20/29) in the acupoint application group (both P < 0.05). After treatment, the scores of spontaneous conversation, restatement and nomenclature in the speech function were all improved as compared with those before treatment in the three groups (all P < 0.01). The results in the combined therapy group were apparently better than those in the acupuncture group and the acupoint application group (all P < 0.01).

CONCLUSIONThe combined therapy of acupoint application of jieyu plaster and acupuncture apparently improves the speech function in the treatment of post-stroke motor aphasia and the efficacy is better than that of simple acupuncture or simple acupoint application.

Objective To investigate the value of N-termind pro-B-type natriuretic peptide(NT-pro-BNP)in differential diagnosis of dyspnea in emergency department, and to investigate the rapid diagnosis cutoff of dyspnea due to acute congestive heart failure. Methods Ninety. one cases of dyspnea in emergency department recruited from January to June ,2008 were divided into two groups: acute cardiac dyspnea group and none acute cardiac dyspnea group. To evaluate the value of different parameters in differential diagnosis of dyspnea in emergency department and analysis the area under the receiver-operating characteristic of different parameters for the diagnosis of acute cardiac dyspnea. To achieve the best cutoff of different parameters for the diagnosis of dyspnea due to acute congestive heart failure finally. Results Among two groups, NT-pro-BNP (acute cardiac dyspnea vs. none acute cardiac dyspnea,6203.50 ng/L vs. 1410.00 ng/L,P ＜ 0.01), Troponin Ⅰ (acute cardiac dyspnea vs. none acute cardiac dyspnea,0.12 μg/L vs. 0.03 μg/L,P ＜0.01) ,left ventricular ejection fraction(acute cardiac dyspnea vs. none acute cardiac dyspnea,46.25% vs. 65.60%, P ＜ 0.01), left atrial diameter (acute cardiac dyspnea vs. none acute cardiac dyspnea,42.75 mm vs. 36.00 mm,P ＜0.01) had significant difference. NT-pro-BNP at cutoff of ≥3715 ng/L was highly sensitive and specific for the diagnosis of acute cardiac dyspnea. Receiver-operating characteristic analyses demonstrated that NT-pro-BNP and left ventricular ejection fraction was the best diagnostic indices of acute cardiac dyspnea. The area under the receiver-operating characteristic curve of Nt-pro-BNP was 0.828 ± 0.045 (P ＜ 0.01),and left ventricular ejection fraction was 0.829 ± 0.049 (P ＜ 0.01). Correlation analysis showed that NT-pro-BNP was correlated with left ventricular ejection fraction (P ＜ 0.01). The combined test of NT-pro-BNP and left ventricular ejection fraction was performed. Specificity increased to 96.50%, total consistent rate increased to 83.50% ,positive predictive value increased to 91.30%, positive likelihood ratio 17.60, faulse diagnostic rate decreased to 3.50%. Conclusions NT-pro-BNP examination in emergency department was helpful to rapid differential diagnosis of dyspnea. It helped to differentiate the patients with acute congestive heart failure and none acute congestive heart failure causes of dyspnea.

Objective To investigate the prevalence of dermatosis affecting pilots in different areas. Methods From Oct. 2007 to Sep. 2008,epidemiological investigation and clinical examination were carried out in 255 pilots stationed at Beijing,Tianjin,Hubei and Shaanxi regions. In order to get the correct diagnosis of dermatosis and the accurate number of infection cases/time,same medication and management were applied for the treatment of those skin disorders. The epideomology of dermatosis in pilots of different troops and age groups were then compared,and the correlation factors affecting the epidemics were analyzed with Chi-square test. Results Among 255 pilots,430 cases (times) were found to suffer from 47 kinds of dermatosis,of whom 72% suffered from two or more kinds of dermatosis. The incidence of superficial mycosis (69.8%) took ranked the highest. The incidence of dermatosis was different among the pilots stationed in different regions. The prevalence of lichen simplex chronicus was higher in the pilots stationed in Beijing,Tianjin and Shaanxi regions than in those in Hubei region,while the prevalence of tinea manuum and tinea pedis showed the opposite status (P 7 year enlistment (P

Objective To analyze the clinical and immunological features of 45 pediatric patients with lupus nephritis (LN). Methods Forty-five LN patients were included in this study. Clinical, pathological data and immunological parameters were retrospectively analyzed. Results Forty-five LN patients had 6 males and 39 females, with the mean onset age of (10.9 ± 2.8) years. Acute nephritis was the most common type, accounting for 42.2%. Nephrotic syndrome accounted for 31.1%. Renal biopsy showed class II (17.8%), III (4.4%), IV (48.9%), V (2.2%), V+III (6.7%)and V+IV (13.3%)in 42 cases. The remis-sion rate reached 91.1%in the early therapeutic stage, and 15.0%patients recurred after 24-month follow-up. Conclusions The clinical manifestations of LN children are diverse. The renal pathology is complex. The clinical manifestations in part of the chil-dren are not consistent with renal pathology.

Objective To investigate the effect of partial sleep deprivation (PSD) on cardiac electric activity and function of vascular endothelium. Methods Eighteen Sprague-Dawley rats were randomly divided into two groups (9 each):PSD group and control group. PSD lasted 10 days,20 hours each day. Body weight and surface electrocardiogram (S-ECG) were examined and recorded 1d before PSD,and 1d,4d,7d and 10d after PSD. Serum concentrations of glucose,total cholesterol (TC),triglyceride (TG),high-density lipoprotein cholesterol (HDL-C),low-density lipoprotein cholesterol (LDL-C),creatin kinase (CK),creatin kinase-MB (CK-MB),high-sensitivity C-reactive protein (hs-CRP),nitric oxide (NO),von Willebrand factor (vWf),endothelin-1 (ET-1) and E-selectin were determined the next day after 10d of PSD. Results Compared to that 1d before PSD,body weight in PSD groups decreased significantly,while increased obviously in control group. Compared to that in control group,the body weight of rats decreased significantly (P

AIM: To investigate the role of CD2AP and F-actin in the pathogenesis of puromycin aminonucleoside nephrosis in rats. METHODS: Puromycin aminonucleoside nephrosis was induced by single intraperitoneal injection of puromycin aminonucleoside (PAN). Renal tissues were studied at 3, 7, 10 and 20 days after PAN injection by means of immunohistochemistry, RT-PCR, Western blotting and fluorescence. RESULTS: At day 3, CD2AP expression in podocytes began to decrease, and significantly decreased at day 7 and 10 (P

Objective To summarize the clinical characteristics and laboratory test results of children with Henoch - Schonlein purpura(HSP),and further to analyze the risk factors for HSP combined with cardiac damage. Methods The clinical and laboratory tests findings from 707 children diagnosed as HSP at Nanjing Children's Hospi-tal were retrospectively analyzed,who were recruited from November 2011 to December 2012. The possible risk factors for HSP with cardiac damage in children were recorded,including gender,age,predisposing causes,gastrointestinal symptoms,joint pain,kidney disorders,serum electrolytes,anti - streptolysin 〝O〝 test,erythrocyte sedimentation rate, and complement level were summarized. Chi - square test and Logistic regression were performed to analyze the risk fac-tors of cardiac damage in children with HSP. Results Among 707 cases,192(27. 2% )patients were combined with car-diac damage,115 male and 77 female,and the proportion of men to women was 1. 00: 0. 67;age ranged from 11 months to 15 years and 4 months(6 years and 5 months for median age),6 patients ﹤ 3 years old occupying 3. 1% ,103 patients≥3 - 7 years old occupying 53. 7% ,82 patients≥7 - 14 years old occupying 42. 7% ,1 patient≥14 years old occupying 0. 5% ,and the age of onset in preschool and school age. Electrocardiogram(ECG)abnormalities were found in 190 patients,the main manifestations including long Q - T interval,ST - T segment falling down and sinus bradycar-dia,and one or more items of abnormal myocardial enzymes existed in 24 cases;echocardiography was performed in 35 cases of children,but no abnormality was detected,no obvious symptoms such as flustered or chest tightness or precor-dial distress. Statistical analysis showed that gender,predisposing causes,mixed HSP,complement level were related to the incidence of cardiac damage in children with HSP(P ﹤ 0. 05). Furthermore binary Logistic regression identified that in male patients,the ratio of X1 vs OR ratio was 0. 654(95% CI 0. 462 - 0. 926,P ﹤ 0. 05),for predisposing causes,the ratio of X2 vs OR ratio was 2. 63(95% CI 1. 838 - 3. 765,P ﹤ 0. 001),for mixed HSP,the ratio of X3 vs OR ratio was 2. 452(95% CI 1. 301 - 4. 621,P ﹤ 0. 01),which were independent factors for cardiac damage in chil-dren with HSP. Conclusions ECG and/ or myocardial enzyme spectrum abnormalities are the main clinical ma-nifestations of cardiac damage in children with HSP. Male patients,predisposing causes of the respiratory tract infec-tion,mixed HSP and hypocomplementemia were high risk factors in the development of cardiac damage,which require special consideration clinically,and earlier ECG and myocardial enzymes examination,early diagnosis and treatment are necessary to avoid the occurrence of severe cases.

Objective To establish a short-term scenario simulation training campus in senior med-ical students before graduation for the sake of a smooth transformation from medical students to residents. Methods There were 101 participants involved in the study . All the participants attended emergency medicine traditional teaching, including 51 fourth-year medical students and 50 fifth-year medical students. The 48 students who took the emergency scenario simulation training course were classified as training camp group while the other 53 students were classified as control group. The control group only participated in the emergency medicine traditional teaching, and the training camp group participated in the emergency sce-nario simulation training course on the basis of control group's routine teaching, including advanced cardiac life support and team collaboration, sepsis and doctor-patient communication, polypnea and crisis manage-ment, disorder of consciousness and interdisciplinary teamwork, multiple injuries and emergency plans, and comprehensive case evaluation. The training camp group was divided into groups and received evaluation of performance on treating emergency simulated case (clinical skills, teamwork, doctor-patient communication) before and after class. The training camp group was received questionnaire survey after class. SAS 9.2 was used to do the t test and descriptive analysis. Results There were no statistically significant differences (P>0.05) between the scores of the performance on clinical skills, teamwork, doctor-patient communication of training camp group and control group before class. The scores of training camp group after class were sig-nificantly better than those of control group (P<0.05). In addition, the course had a high recognition by students. 92% (44/48) students thought the course was contributed to improving the ability of crisis man-agement and clinical practice and were in favor of developing similar courses for senior medical students. Conclusion Scenario simulation training campus can strengthen the cultivation of medical students' com-prehensive thinking, independent clinical decision making, practice skills and communication ability in the final stage of medical education as well as enhancing their self-confidence so as to help them to adapt to the real clinical work.

Objective To detect the signaling pathways involved in aldosterone (ALDO)induced mesangial cell (MC) proliferation. Methods The incorporation of 3H-thymidine (3H-TdR)and cell count were used as the measure of mesangial cell (MC) proliferation. Reactive oxygen species (ROS) production was determined by DCFDA fluorescence. Epidermal growth factor receptor (EGFR) activation was assayed by Western blotting. Results ALDO induced MC proliferation.When incubation with 100 nmol/L ALDO for 24 h, the 3H-TdR incorporation and cell number increased by 2.63- and 2.15-fold, respectively. Mineralocorticoid receptor (MR) antagonist EPLE almost completely blocked ALDO-induced MC proliferation (P<0.01), however, glucocorticoid receptor (GR) antagonist RU-486 had no effect on MC proliferation. ALDO increased intracellular ROS production in cultured human MCs. When incubation with ALDO (100 nmol/L) for 60 min,ROS production increased by 2.14-fold. ALDO-induced ROS generation was completely blocked by EPLE as well as mitochondrial complex Ⅰ inhibitor rotenone (P<0.01=, NADPH oxidase inhibitors diphenyleneiodonium sulfate (DPI) and apocynin inhibited ALDO-induced ROS production by 30%to 35% (P<0.05=. In contrast, inhibitors of other oxidant-producing enzymes, including allopurinol,indomethacin, nordihydroguiaretic acid, ketoconazole and G-nitro-L-arginine methyl ester (L-NAME)had no effect on ALDO-induced ROS production. Antioxidant N-acetyl-L-cysteine (NAC) and ROT inhibited ALDO-induced MC proliferation by 75% to 80%, whereas the inhibition of NADPH oxidase inhibitor apocynin and DPI on ALDO-induced MC proliferation was 25% to 30%. ALDO induced EGFR transactivation. When incubation with 100 nmol/L ALDO for 60 min, EGFR phosphorylation was increased by 4.95-fold, which was completely inhibited by EPLE and antioxidant NAC (P<0.01=. NAC and EGFR antagonist AG1478 significantly blocked ALDO-induced MC proliferation (P<0.01=. Conclusions ALDO-induced MC proliferation is mediated by ROS-dependent EGFR transactivation. ALDO-stimulated ROS is mainly generated by mitochondria.

Objective To investigate the role of oxidative stress-dependent Rasextracellular signal-regulated kinase (ERK1/2) signaling in aldosterone (ALDO)-induced mesangial cell proliferation. Methods The incorporation of 3H-thymidine (3H-TdR) and cell count were used as the measure of mesangial cell (MC) proliferation.Western blotting was used to detect the activation of Ki-RasA,c-Raf,MEK1/2,ERK1/2 and PI3K. Results Aldosterone significantly induced human mesangial cell proliferation,and anti-oxidant N-Acetylcysteine (NAC),catalase,and super oxide dismutase (SOD) significantly inhibited ALDO-induced mesangial cell proliferation (P＜0.01,respectively).Stimulation by ALDO for 3 h,Ki-RasA,c-Raf,MEK1/2,and ERK1/2 activity increased by 4.05-, 3.62-, 4.52-, and 3.40-fold compared with control group (P ＜0.01,respectively).NAC almost completely blocked ALDO-induced Ki-RasA,c-Raf,MEK1/2,and ERK1/2 activation (P＜0.01,respectively).Ki-RasA siRNA dose-dependently inhibited Ki-RasA expression, ALDO-induced Ki-RasA activation, and mesangial cell proliferation (P ＜0.01,respectively).c-Raf inhibitor GW5074 and MEK1/2 inhibitor PD98059 also reduced ALDO-induced mesangial cell proliferation by 65％ respectvely (P＜0.01).Ki-RasA siRNA had no effect on ALDO-induced PI3K phosphorylation.Combining LY294002 and PD98059 completely blocked ALDO-induced mesangial cell proliferation (P＜0.01). Conclusions ALDO-induced Ki-RasA-c-Raf-MEK-ERK signaling activation is dependent on reactive oxygen species (ROS) production,which mediates ALDO-induced mesangial cell proliferation.Inhibition of both ERK1/2 and PI3K signaling simultaneously completely blocks ALDO-induced mesangial cell proliferation.
