Objective To explore the brain CT index,neurological scores and efficacy of ganglion glycosides in treating neonatal hypoxic ischemic encephalopathy (HIE).Methods Seventy-two patients with HIE hospitalized in our hospital were randomly selected as the research objects during November 2012 to November 2014.The patients were divided into observation group(36 cases) and control group(36 cases) according to the time of admission.The patients in control group were treated with routine treatment.The observation group was treated with ganglion glycosides on the basis of the conventional treatment.After two weeks treatment,the brain CT index,neurological scores and efficacy were observed.Results After treatnent,with CT examination the patients in the observation group showed mild HIE in 33 cases,which was significantly more than the control group,and severe HIE in 3 cases,which was significantly less than the control group.There were significant differences between the two groups (x2 =7.005 4,11.840 2,all P ＜ 0.05).The recovery time of consciousness,reflex recovery time,recovery time of muscle tension of the observation group were (5.08 ± 1.02) d,(6.74 ± 1.53) d,(7.31 ± 1.69) d,which were shorter than the control group,and the differences between the two groups were statistically significant (t =13.002 7,5.354 6,6.224 0,all P ＜ 0.05).After treatment,there were no deaths in the two groups,the observation group of 1 patient with ataxia,2 cases of mental retardation,epilepsy in 1 case and 0 case of cerebral palsy,which were less than the control group,there were significant differences between the two groups (x2 =7.407 4,P ＜ 0.05).Conclusion For the newborn with HIE after treating with ganglion glycosides,the CT index and neurological score showed obvious improvement,and the treatment effect is good,thus it is worth popularizing.

The solid pseudopapillary tumor of pancreas (SPT) is a rare pancreatic tumor with low malignant potential. It primarily affects young women. The clinical characteristic is nonspecific, but the pathological characteristic is distinct. The tumor consists of both cystic and solid component. The typical histopathological appearance of SPT is the pseudopapillary structure with a fibrovascular surrounded by several layers of epithelial cells.Only a few SPTs present invasive behaviors. The tumor cells express a wide range of immunohistochemical markers. The pathogenesis is associated with the Wnt signaling pathway, which is changed by β-catenin, Pl20-catenin, adenomatous polyposis coli gene( APC), the cyclin-dependent kinase inhibitors p21 and p27.

The da Vinci robotic surgical system has the advantages of three-dimensional vision and high degree of accuracy,flexibility and repeatability,which makes surgical procedures such as digestive tract anastomosis easier to conduct under minimally invasive conditions.In this article,the feasibility and principle of digestive tract anastomosis and the procedures of pancreaticojejunostomy and pancreaticogastrostomy by the da Vinci robotic surgical system are introduced,so as to improve the quality of anastomosis and reduce the incidences of postoperative complications.Compared with traditional laparotomy,da Vinci robotic surgical system simplified the surgical procedures and reduced the trauma,which is suitable for digestive tract anastomosis in pancreatic surgery.The method of pancreatic anastomosis should be selected in consideration of the condition of patients,surgical procedure and the experience of surgeons.

OBJECTIVE: To determine the effect of trimetazidine on cardiac function and exercise tolerance in primary hypertension patients with type 2 diabetic. METHODS: In this randomized, double-blind, placebo-controlled prospective study, 60 primary hypertensive patients with diabetic were equally assigned into two groups, patients received trimetazidine (20 mg, 3 times a day) or placebo for 1 year. Echocardiography, cardiopulmonary exercise testing were performed; and the plasma N terminal pro B type natriuretic peptide (NT-ProBNP), hr-CRP, TNF-α, angiotensin Ⅱ and endothelin concentration were determined before and after treatment. RESULTS: In trimetazidine group, the left ventricular mass index, the mitral flow velocity E wave to A wave ratio (E/A), the peak early diastolic velocity (V) to late diastolic velocity (V) ratio (V/V) and the peak systolic velocity (Vs) were significantly improved, the plasma NT-ProBNP level was significantly decreased, and the exercise time, metabolic equivalent, maximal oxygen uptake and anaerobic threshold were significantly increased (all <0.05); plasma concentration of hr-CRP, TNF-α, angiotensin Ⅱ and endothelin were significantly reduced after trimetazidine treatment, compared with baseline (all <0.05) and with placebo (all <0.05). There were no significant differences in any of above parameters after treatment in placebo group (all >0.05). No severe adverse reaction was observed in both groups. CONCLUSIONS For patients with both hypertension and diabetes, trimetazidine can improve cardiac function and increase exercise tolerance.

Conclusion Liraglutide can improve bone mineral density and bone metabolism in type 2 diabetic rats with osteoporosis, which may be related to activation of Wnt pathway.

Objective To analyze the regulation of NEF3 expression in SH - SY5Y after RA induction. Methods The expression of NEF3 and Brg1 genes was individually detected by realtime RT - PCR and Western blot analyses. Then, the CAT reporter driven by 5' flanking region ofNEF3 gene (pBLCAT3 -2. 8k - NEF3) was co - transfccted with eukaryotic expression plasmids of pBJ5 - Brgl or pBJ5 - Brg1 - NTP into SH - SY5Y respectively. Promoter activity of the NEF3 gene was detected by competitive RT - PCR assay. Results Similar changes in the mRNA expression of NEF3 and Brg1 and that of the protein expression of Brgl were detected in Sh - SY5Y cells af-ter RA treatment for 12 -24h. Wild type Brgl can promote the expression of pBLCAT3 -2.8k -NEF3 promoter after RA induction, but not mutant Brg1. Conclusion Brgl helpes regulating the expression of NEF3 gene possibly via changes in chromatin conformation in the SH -SY5Y cells after RA induction.

Pancreatic cancer is a highly malignant tumor. Animal models of pancreatic cancer included xenograft models, carcinogen induced models, genetically engineered models. Xenograft models are relatively reliable and feasible, but the growth pattern is different between serve immunodeficienct animals and human beings. Carcinogens induced models simulated the environmental factors to reconstruct the development of pancreatic cancer. But carcinogens could have other biological effects. Genetically engineered models could make the occurrence of pancreatic cancer at the molecular level. But it is difficult to control the transgenic product accurately. No model could meet all the needs of different experiments. It is important to choose a suitable animal model in different experiments.

OBJECTIVETo investigate the effects of different ventilation modes for one lung ventilation anesthesia on arterial blood-gas, airway pressure, intrapulmonary shunt, and F(A)/F(I) changes in patients receiving sevoflurane inhalation.

METHODSThirty ASA class II-III patients with lung cancer undergoing pulmonary lobectomy were randomized into 3 equal groups. The patients in group A received volume-controlled ventilation (VCV) without positive end-expiratory pressure (PEEP) (VT=8 ml/kg, Rf=12/min), and those in group B, after a preceding VCV stabilize the airway pressure, had pressure-controlled ventilation with maintenance of an identical peak pressure (Ppeak) (Rf=12/min, PEEP=0). In group C, the patients received small tidal volume ventilation with PEEP (VT=6 ml/kg, Rf=16/min, PEEP=5 cm H(2)O). Blood gas analysis was carried out at 10 min after TLV and at 20, 45 and 70 min after one lung ventilation (OLV); the heart rate (HR), mean arterial pressure (MAP), SpO(2) and Ppeak were also recorded and blood samples collected from the artery and jugular vein at these time points. Inhalation of 1.5% sevoflurane for 20 min started at 20 min of OLV.

RESULTSCompared with those in TLV, the Ppeak increased, lung compliance decreased, arterial oxygenation (PaO(2)) decreased and intrapulmonary shunt (Qs/Qt) increased during OLV. Group B showed the fastest increase of F(A)/F(I) in the initial 8 min, followed by groups A and C, but the curves became similar with the passage of time.

CONCLUSIONSDuring OLV, the 3 ventilation modes result in similar F(A)/F(I) changes during sevoflurane inhalation but PCV can increase pulmonary compliance.
