Objective; To investigate the immunolocalization and significance of Notch-2 expression in the process of dental pulp repair after injury. Methods: An experimental animal model of injury-induced pulpitis was established to observe the time-sequenced alteration of the expression of Notch-2. Results: Three days post-operation, weak positive staining of Notch-2 was observed in pulp mesenchyme cells and pulp fibroblasts but not in vascular endothelial cells or odontoblasts. Five days post-operation, strong Notch-2 reactivity was found in subodontoblasts as well as newly bom capillary endothelial cells. Seven days after cavity preparation, Notch-2 staining became weaker in pulp mesenchyme cells and capillary endothelial cells, but stronger positive staining was found in odontoblasts. Two weeks post-operation, weak Notch-2 staining was seen in pulp mesenchyme cells and subodontoblastic layer cells and was absent from odontoblasts. Notch-2 immunoreactivity was completely absent in intact rat dental pulp. Conclusion: Notch-2 is strikingly up-regulated in dental pulp mesenchyme cells in the early days after dental injury and then shows progressively up-regulation in odontoblasts. Properly regulated activation of Notch signaling pathway is important for controlling cell fate and maintaining the correct balance among cell proliferation, differentiation and apoptosis during dental pulp repair process.

Objective:To explore diagnostic effects of 24h dynamic electrocardiogram (DCG) on pacemaker-induced rapid arrhythmias of different locations.Methods: Clinical data of 86 patients, who received pacemaker implantation in our hospital from Feb 2013 to Jan 2016, were retrospectively analyzed.According to ventricular electrode placement location, patients were divided into right ventricular septum (RVS) pacing group (RVS group, n=43) and right ventricular apex (RVA) pacing group (RVA group, n=43).The Tp-Te interval and occurrence of arrhythmias detected by 24h DCG were recorded and compared between two groups.Results: All patients received pacemaker implantation successfully, and pacemaker was fixed on RVS or RVA.There were no significant difference in pacing threshold, impedance and R wave amplitude between two groups, P>0.05 all.Compared with RVA group, there were significant reductions in Tp-Te intervals of V3 lead [(102.78±19.24)ms vs.(94.39±18.56)ms] and V4 lead [(96.39±13.11)ms vs.(85.87±14.59)ms] in RVS group (P=0.001 both).There were no significant difference in incidence rates of sinus arrest, II° sinoatrial block, atrioventricular block, atrial premature beats, transient paroxysmal atrial tachycardia and ventricular premature beats between two groups (P>0.05 all).Conclusion: The 24h DCG indicates that compared with RVA pacing, the Tp-Te interval of RVS pacing group significantly shorten, it may can better protect cardiac function.

Objective To investigate the effects of Puerarin on glucose and lipid metabolism and gastric motility in early period type 2 diabetic (T2DM) rats.Methods Rat model of T2DM was established by high fat-sugar diet fed and low-dose streptozotocin-treated. SD rats were divided randomly into normal control group (NC), normal+Puerarin group (NP), diabetes control group (DC) and diabetes+Puerarin group (DP). NP and DP rats were given Puerarin 400 mg/(kg?d) once per day for 5 weeks, NC and DC rats were given PBS. Half time of gastric emptying and emptying rate were evaluated by SPECT. The serum level of FBG, GSP, FFA, TC, TG and INS were measured by kit.Results Compared with NC group, DC rats had higher FBG, FFA, TC, GSP, TG and emptying rate, but INS and half time of gastric emptying decreased significantly (P<0.05,P<0.01). Compared with DC group, TG, GSP, FFA and emptying rate of DP rats were reduced (P<0.05), but had more half time of gastric emptying (P<0.05). The results of multivariate stepwise regression analysis showed that FBG related to half time of gastric emptying.Conclusion Type 2 diabetic rats have faster gastric motility, higher blood glucose and lipid. Puerarin might improve the disorders of GSP, TG, FFA and gastric emptying in diabetic rats.

Objective:To observe the effect of Jianpi Xiaozhang tablets on the bile secretion in rats. Methods: Totally 60 rats were divided into 6 groups randomly. Jianpi Xiaozhang tablet suspension(high, moderate, low dosages), Shudantong suspension, Qinggan Lidan capsule suspension and 0. 5% carboxymethyl cellulose with the same volume was respectively given with intragastric ga-vage once daily for continuous 5 days. The bile was collected to detect total bile acids ( TBA) , total cholesterol and total bilirubin. Re-sults:Jianpi Xiaozhang tablets could notably increase TBA and total bilirubin in the bile (P<0. 01), and decrease the cholesterol content significantly (P<0. 01). Conclusion:Jianpi Xiaozhang tablets can promote the bile secretion.

Objective To investigate the prenatal diagnosis, perinatal management and standardized treatment protocol for neonates with duodenal obstruction. Methods A network in prenatal diagnosis, perinatal management and monitoring of congenital malformation was founded between Beijing Obstetrics and Gynecology Hospital and the Capital Institute of Pediatrics. Forty-four fetuses were prenatally diagnosed as duodenal obstructions by this network from July,2001 to September, 2010. The data of prenatal diagnosis, treatment after birth and prognosis were analyzed. Results Among 44 patients diagnosed as fetal duodenal obstruction by prenatal ultrasonography, three cases underwent induced abortion, three were in pregnancy, 14 were lost during follow-up and 24 were confirmed by surgical treatments after birth. Within 24 neonates underwent surgery, 21 showed double-bubble sign and 20 combined with polyhydroamnios in prenatal ultrasonography. Twenty-four neonates underwent upright abdominal plain film examination,22 showed double-bubble sign, 1 showed single-bubble sign and 1 showed triple-bubble sign,respectively. Nineteen neonates underwent upper gastroenterography which showed distention of stomach and duodenum, increased stomach peristalsis and an obstacle of duodenum emptying. Within 23 neonates underwent ultrasonographic studies, 10 showed distention and increased peristalsis of duodenum. Following surgical procedures were performed: diamond shape anastomosis was completed in 19 cases with annular pancreas; duodenal vertical resection, across suture and excision of the membrane was done in four cases with duodenum membranate stenosis; end-to-back anastomosis was taken in one case with duodenal separate atresia; Ladd's procedure was applied in 11 cases associated with malrotation. All patients were cured. Conclusions Standardized perinatal management and earlier intervention should be offered to newborns with duodenal obstruction to achieve better effects.

Objective To investigate the efficacy of standardized protocol,including prenatal diagnosis,perinatal management and treatment,on babies with meconium peritonitis.Methods A standardized protocol with prenatal diagnosis,perinatal management,treatment and follow-up on congenital anomaly was founded by Capital Institute of Pediatrics and several other obstetric hospitals.Thirty neonates diagnosed as meconium peritonitis prenatally from March 15,2006 to August 27,2012 were intervened according to this protoccl.The data of diagnosis,treatment after birth and prognosis were analyzed.Results (1) Prenatal diagnosis:Abnormal meconium peritonitis relative signs were found by ultrasound in all of these 30 cases.Among them,23 cases presented with intestine dilation,15 with polyhydromnios,nine with ascites,four with abdominal cystic mass and four calcification.(2)Diagnosis after birth (n=27):The most common imaging findings in abdominal X-ray were distention (27 cases),dilated intestine with air-fluid levels (22 cases) and calcification (11 cases).The most common imaging findings in ultrasound were obvious intestinal dilation (19 cases),cystic mass (7 cases) and calcification (7 cases).(3) Operation:Except for three cases without symptoms,the other 27 infants received operation at averagely 42 hours after birth (12 h-5 d).Besides the basic treatment as removal of the fuci and dissection of adhesion,peritoneal drainage was performed in one infant,two-stoma enterostomy in seven infants,inverted T-shape enterostomy in eight infants and primary intestinal anastomosis in 11 infants.Among these 27 cases,24 cases were cured,2 cases refused following treatment after surgery and one case was lost to follow up.Conclusions Standardized protocol with prenatal diagnosis,perinatal management and earlier intervention might improve the prognosis of meconium peritonitis.
