Objective To study the clinical effects of tearing pediatric diarrhea with traditional Chinese and western medicine.Methods Altogether 520 patients with pediatric diarrhoea were recruited into three groups:the group treated with combined traditional Chinese and western medicine,the group treated with Chinese medicine and the group treated with western medicine.Observe clinical effects of each group.Results In 175 cases of the group treated with combined traditional Chinese and western medicine,66 cases show significant effects,64 cases are effective,45 eases are ineffective,and the effective rate is 74.30%;In 171 cases of the group of treated with traditional Chinese medicine,32 eases show significant effects,42 eases are effective,97 cases are ineffective,and the effective rate is 43.30%;In 174 eases of the group of treated with western medicine,35 eases show significant effects,43 eases are effective,96 eases are ineffective,and the effective rate is 44.80%.The effective rate of the group treated with combined Chinese medicine and western medicine was significantly better than the other two groups (P＜0.01).Conclusion Combined Chinese and western medicine is more effective in treating the patients with pediatric diarrhea,and it is worthy of spread.

Objective To explore the effect of an electromagnetic field (EMF) on the viability,proliferation and osteogenic differentiation of rats' bone mesenchymal stem cells (rBMSC).Methods Sinusoidal 1mT EMFs of 10 Hz,30 Hz,50 Hz and 70 Hz were administered to rBMSC for 2 hours per day during 2 weeks of cultivation.The cell viability was analyzed using live/dead assays.The cells' DNA was quantified to evaluate cell proliferation.Von Kossa staining was performed to study the mineralization of the extracellular matrix.The enzyme linked immunosorbent assay (ELISA) and immunohistological staining were employed to observe the synthesis of osteocalcin (OC) and bone morphogenetic protein-2 (BMP-2).Results Cell viability decreased under exposure to the 50 Hz and 70 Hz fields.The proliferation of rBMSC was elevated significantly in the 10 Hz EMF-treated group.The expression OC and BMP-2 was elevated after two weeks of 50 Hz EMF stimulation.Moreover,the mineralization of the extracellular matrix was found to be enhanced after 50 Hz EMF exposure.Conclusion Exposure to a 1 mT EMF has different effects on the viability,proliferation and osteogenic differentiation of rBMSC depending on the frequency.The data provide practical guidance for applying electromagnetic fields in bone regenerative medicine.

AIM: To investigate the effects of electrical stimulation of vagus nerve on gut injury following intestinal ischemia-reperfusion in rats. METHODS: 30 adult male Wistar rats subjected to bilateral cervical vagotomy were randomly divided into three groups (n=10 per group): (1) Intestinal ischemia-reperfusion group (group I/R): laparotomy and I/R induced by clamping arteria mesenterica superior for 1 h followed by reperfusion for 2 h. (2) Vagus nerve stimulation group (group VNS): laparotomy, I/R and electric stimulation with pulse train of constant amplitude 5V, pulse width 2 ms and frequency 1 Hz at the left caudal vagus ends for 20 minutes before and after occlusion. (3) Sham control group (group SC): sham operation and sham stimulation. Carotid artery was cannulated for mean arterial pressure (MAP) monitoring. A strip of small intestine was taken from distal end of ileum for light microscopic (LM) and transient electron microscopic (TEM) examination at the time of 2 h after reperfusion. Improved Chiu’s scale was used to quantitatively assay the damage degree. The levels of malondialdehyde (MDA) and TNF-? in plasma were detected. RESULTS: MAP in every group kept steady during ischemia, but decreased gradually with the prolongation in the time of reperfusion. MAP decreased more dramaticly in group I/R than that in group VNS (P

Objective To explore the advantages and disadvantages between the RapidArc plans and fixed-field IMRT plan (IMRT).Methods Ten cases of cervical cancer,aged 55 (36-70),who were to receive post-operative radiotherapy were selected randomly.Single arc (Arc 1),two arcs (Arc 2),and three arc (Arc 3) RapidArc plans and fixed-field IMRT plan were designed respectively in the Eclipse 8.6 planning system.The designing,treatment time,target area,and dose distribution of organs at risk by these 4 planning techniques were compared.Results The values of average planned treatment time by the Arc 1,Arc 2,and Arc 3 ten cases was 98,155,185,and 46 min,respectively.The values of average treatment time in the Varian IX accelerator were 2.15,3.32,4.48,and 6.95 min,respectively.The average mean doses were (48.99±1.08),(49.40±0.51) ,(49.51±0.62) ,and (48.65±0.92) Gy,respectively.The values of homogeneity index (HI) of target were 1.11±0.07,1.07±0.02,1.06±0.02,and 1.12±0.05,respectively.The values of eonformal index (CI) of target were 0.73±0.13,0.87±0.06,0.87±0.06,and 0.79±0.06,respectively.The doses at rectum,bladder,and small intestine calculated by IMRT plan were the lowest,and the doses at the femoral neck calculated by these 4 plans were similar.Conclusions The RapidArc plan is superior in dose distribution at target,HI,CI,and treatment time to IMRT,but IMRT plan is superior to RapidArc in planned dose calculation time and protection of organs at risk.However,in general,the RapidArc plan is better in clinical application than IMRT plan.

Objective To investigate the relationship between the level of mindfulness and the A-type behavior characteristics of the nursing college students.Methods 172 nursing college students were investigated by the scale of TABP and FFMQ.The results were analyzed.Results In the 172 nursing college students,there were 112 nursing college students belonging to type B behavior pattern,accounted for 65.1％,and 60 nursing college students belonging to type A behavior pattern,accounted for 34.9％.The correlation between the score of TABP and the observation items and describing items were positive statistically significant,and was negatively correlated with awareness items and non-judge items statistically.Conclusions The students with different behavior characteristics were different in their mindfulness level.In order to improve nursing college students' mindfulness level and their mental health,the educators should take intervention based on their behavior characteristics timely.

Objective To identify novel biomarker for diabetic nephropathy (DN) by urinary proteomic methods,and to detect the expression of E-cadherin in urine and renal tissue of patients with DN.Methods Urine samples were collected from 12 cases of type 1 diabetic nephropathy patients (T1DN),12 cases of type 2 diabetic nephropathy patients (T2DN),12 cases of nephritic syndrome patients (NS),and 12 cases of healthy Controls.Comparative proteomic approach of two-dimensional gel electrophoresis (2-DE) and mass spectrometry (MS) were employed to identify DN-related biomarker in urine samples.The differential expression of the identified biomarker in urine samples and renal biopsy specimens were detected by Western blotting and immunohistochemistry method.Results E-cadherin was identified by 2DE/MS,which was significantly up-regulated in T1DN and T2DN groups (all P ＜0.01).Western blotting confirmed the expression of E-cadherin was significantly higher in T1DN and T2DN groups than in NS and Control groups (all P＜0.01).Immunohistochemical stain showed E-cadherin was mainly expressed in the membrane and cytoplasm of renal tubular epithelial cell,and its expression was markedly decreased in DN kidneys compared with healthy Controls (P ＜ 0.05).Conclusions E-cadherin is identified as a novel DN-related biomarker,which is specifically increased in urine of DN patients.
