Modern Hospital 2014;(8):61-62
Objective To investigate the effects of hypertonic saline in the treatment of children with critical hand, foot and mouth disease (HFMD).Methods The 250 pediatric patients with HFMD hospitalized from January 2011 to Januar-y 2013 in our hospital were randomized into the control group treated routinely and the experimental group treated with hyper-tonic saline on the basis of general conventional treatment .The therapeutic effect and sodium ion concentration in the children of two groups were observed and compared.Results The treatment effect of the experimental group was obviously better than that of the control group (p<0.05).Sodium ion concentration and incidence of adverse reactions in two groups before treat-ment showed no significant differences (p>0.05), while the sodium ion concentration of the experimental group was much higher than that of the control group on the 4th and 6th treatment day (p<0.05).Conclusion Hypertonic saline treatment can significantly enhance the therapeutic effect, increase the sodium ion concentration and improve the prognosis in children with critical HFMD.Therefore, hypertonic saline treatment for patients with clinical HFMD has a very important clinical sig-nificance and it is worth popularization and application.

Objective To determine species, counts, and seasonal variation of airborne pollen in the center of Nanchang. Methods Pollen counts were done with Durham gravity method on the top of the building in the campus of Jiangxi Medical College, Nanchang, April 1, 2000-March 31,2002. Results There were airborne pollens in all seasons of the year in atmosphere of Nanchang, which included about 47 species. The highest airborne presence (percent of total yearly pollen counts) was for Ambrosia(35.73%); followed by Pinaceae (15.94%), Artemisia (11.94%), Gramineae (5.88%), Cupressaceae (5.64%), Cunningha-mia R.Br.(5.12%), Chenopodium-Amaranthus (5.03%) , and Humulus(2.02%). The dispelling period showed a double curve: the first peak occured in Mar. and Apr. (22.56% and 11.98% respectively). The predominant pollens were tree pollen (Pinaceae, Cupressaceae, Cunninghamia R.Br., Moraceae and Salix). The second peak occured in Aug., Sep., and Oct. (9.61%, 23.77%, 19.57% respectively). The predominant pollens were grass pollen (Ambrosia, Artemisia, Gramineae, Chenopodium-Amaranthus and Humulus). Gramineae had been scattering all seasons, but it's counts were not high in every month. Conclusion There are airborne pollens dispelling in atmosphere of Nanchang in the whole year, whose dispelling period shows a double curve (the first peak occurs in Mar. and Apr. And second peak occurs in Aug. Sep. and Oct.) and the predominant pollens are Ambrosia, Pinaceae, Artemisia, Gramineae, Cupressaceae, Cunninghamia R.Br., Chenopodium-Amaranthus and Humulus. This study provides useful scientific information for production of specific allergen and for clinical prevention, specific diagnosis, specific therapy of allergic deseases.

Aim To investigate the protective effect of propofol on ischemia-reperfusion(I/R)injury in isolated rat hearts and clarify the possible molecular mechanism from oxidative stress and the apoptosis initiated by mitochondria pathway. Methods The langendorff model of ischemia-reperfusion was used.Forty isolated perfused rat hearts were divided into control,I/R, propofol 15,30,60 ?mol?L-1 groups. Hearts were suffered globally ischemic for 25 min and 30 min with reperfusion. The cardiac function indexs such as the left ventricular developed pressure(LVDP), the left ventricular end diastolic pressure(LVDEP), heart rate (HR), coronary arterial flow (CF) were recorded at the time of equilibrate, before ischemia, the end of reperfusion respectively. The lactate dehydrogenase (LDH), creatine kinase (CK) activities in the flow were measured. The swelling and activity of mitochondria, the activity of Manganese Superoxide Dismutase (Mn-SOD) and content of malondialdehyde (MDA) in myocardium mitochondria were also determined. The incidence of cardiomyocyte apoptosis was evaluated by the TdT-mediated dUTP nick end labeling (TUNEL) staining and the expression of Bcl-2 and Bax were evaluated by Flow Cytometry(FCM). The expression of Caspase-3,8,9 was detected by immunohistochemistry.Results Compared with I/R group, administration of propofol at the concentration of 30 and 60 ?mol?L-1 markedly ameliorated the cardiac function in CF,LVDP and LVDEP(P

Objective To explore the effect of rehabilitation training start time after mastectomy on the recovery of the affected limb function. Methods 90 patients who received modified radical mastectomy were divided into groups A, B and C randomly. All the patients accepted the unified rehabilitation program, but started 1, 3 and 10 d after the operation respectively. They were evaluated with the Japanese Orthopaedics Association (JOA) assessment for affected shoulder 1, 3 and 6 months after operation. Results The score of JOA was the least in the group C (P<0.01) 1 month after operation, and was the most in the group A 3 months after operation (P<0.01). At the end of the 6th month, there was no difference among these groups (P>0.05). Conclusion The rehabilitation training can be started as early as possible.

Aim To investigate whether hydrogen sul-fide ( H2 S ) inhibits cardiomyocyte apoptosis induced by acute myocardial ischemia in isolated perfused rat heart. Methods The myocardial ischemia injury model was replicated with Langendorff isolated perfused rat heart, and the left anterior descending coronary ar-tery was ligated for 4 h. 40 male SD rats were divided into five groups randomly: sham group, ischemia group, and NaHS groups (5,10,20μmol·L-1). The segmental heart samples were used for HE staining. Cardiomyocyte apoptosis was detected with TUNEL as-say. The expressions of caspase-3 and Cyt-C in hearts were determined with Western blot analysis. Results Myocardial cells were found to show serious disorder and coagulated zonal necrosis under light microscope, the apoptotic rate of cardiomyocytes and the expression of caspase-3 and Cyt-C were significantly increased af-ter ischemia for 4h. Perfusion of NaHS resulted in more clear cell morphology and milder pathologic chan-ges of myocardiocytes according to the HE staining a-nalysis, and the significant decrease of expression of Cyt-C. After perfusion of 10,20 μmol·L-1 NaHS,the apoptotic rate of cardiomyocytes and the expression of caspase-3 were significantly decreased. Conclusion H2 S has certain protective effects on acute myocardial ischemic injury in isolated perfused rat heart via inhibi-ting cardiomyocyte apoptosis.
