Pancreaticogastrostomy appears as a method of pancreatic digestive tract reconstruction after pancreaticoduodenectomy.Its research mainly includes incidences of pancreatic-fistula,pancreatic exocrine and endocrine function and methods of pancreaticogastrostomy,which is frequently compared with pancreaticojejunostomy.In this review.The author will discuss these problem and review.The history of pancreaticogastrostomy.

Endothelial progenitor cells(EPCs)are the precursor cells of vascular endothelial cells.EPCs are in bone marrow,peripheral blood and cord blood.They participate in the process of angiogenesis after birth.The stimulation of exogenous and endogenous factors mobilizes bone marrow-derived EPCs into peripheral blood,and participates in the revascularization of ischemic tissue and the process of re-endothelialization of the injured blood vessels.The decreased mmahers and quality of EPCs in blood circulation are one of the most important factors of unfavourable prognosis after ischemic stroke.The transplantation of EPCs may provide a novel therapeutic strategy for the treatment of ischemic cerebrovascular disease.

Information Dissymmetry is a common phenomenon in this economical market.None of us can master all information about anything.The relative difference of the information's occupancy leads to a sharp distinction of the bargainer' status currently.During the service of our hospital library,Information Dissymmetry seriously restricts the development of our library and makes many readers dissatisfied.The author analyzed the problem in progress of service to the reader and finally put forward the countermeasure of this progress reconstruction in the hospital library.

BACKGROUND:Bone marrow mesenchymal stem cels are a kind of non-hematopoietic adult stem cels, mainly distributing in the bone marrow, with strong proliferation and differentiation potential, which has a promising clinical prospect. OBJECTIVE:To review the latest progress in growth factors and biological scaffolds to promote chondrogenic differentiation of bone marrow mesenchymal stem cels. METHODS:PubMed and CNKI databases were searched by the first author using key words of cartilage defects, tissue engineering, biological scaffolds, bone marrow mesenchymal stem cels, cytokines in English and in Chinese, respectively, to retrieve relevant articles published from 1990 to 2014. Literatures addressing the chondrogenic differentiation of bone marrow mesenchymal stem cels were included, and 51 articles were chosen for further analysis eventualy. RESULTS AND CONCLUSION:Bone marrow mesenchymal stem cels have the potential to differentiate into chondrocytes, which can be induced by many cytokines. Various biological scaffolds act as a carrier for chondrogenic differentiation of bone marrow mesenchymal stem cels. But there are stil lots of problems to be solved and in-depth explored clinicaly.

Objective To examine the effects of weight loss on functional state of female judokas. Methods Twelve female judokas belonging to Shanghai female judo team were tested at different periods(first,second,third phases and last phase) during weight loss a month before competition. The changes of physiological and biochemical indexes in different periods were observed and all the data was statistically analyzed. Results Previous three phases,the Fat% in weight loss group was decreased compared with basic data (P

Objectives To investigate the T cell subsets changes in hemorrhagic fever with renal syndrome (HFRS) patients. Methods 22 HFRS patients who were diagnosed in Qin Huang Dao Third Hospital from April 2005 to July 2005 were enrolled in this study and divided into two groups according to clinical manifestations. T cell subsets of the 22 patients were monitored at week 1, 4 and 12. Another 56 subjects were enrolled as healthy controls. Results B cell count was normal during the 12 weeks in all the subjects. NK cell decreased significantly at week 1, and recovered at week 4 rapidly. CD4+ T cell count was normal throughout the course of the disease, but the percentage of memory phenotypy increased at week 1and4, reaching(64.1±17.5)% and (59.9±10.1)%, but recovered at week 12. CD4+CD28+T cells were normal throughout the entire study. CD8+ T cell count increased dramatically at week 1 and 4, but finally recovered at week 12. The count of CD8+ CD28-T cells increased significantly at week 1 in low-grade goup, but in median-grade group, this increase lagged to week 4 and was not as significant as in low-grade group. The percentage of CD38+ or HLA-DR+ subsets of CD8+ T cell increased at week 1, 4. Conclusion The results confirmed the relationship between HFRS progression and cellular immunity. It revealed that, at the early stage of HFRS, rapid and effective cytotoxicity T lymphocyte response my contribute to clear Hantavirus away and improve HFRS symptom.

Objective To observe the analgesic effect of ultrasound-guided and nerve stimulator after artificial total knee athroplasty(TKA).Methods Forty elective cases receiving TKA under gen-eral anesthesia were randomly allocated into the ultrasound group (group C)and stimulator group (group S).The time for nerve block,onset time and complications were recorded in both groups. Results Compared to group S,the time for nerve block and onset time was significantly shortened in group C (P <0.05).There was no statistical difference in times of pressing analgesic pump and VAS score in postoperative 48 h.One patient suffered from nerve injury and two underwent vascular dam-age and hematoma in group S,while no complication was found in group C.Conclusion Compared to nerve stimulator,ultrasound-guided continuous femoral nerve block(CFNB)may reduce nerve block time and onset time and decrease complications,so that to increase safety of CFNB.

Objective To investigate the influence of comprehensive intervention on improving the quality of life of idiosyncratic infants and young children.Methods A control study Was conducted on 106 idiosyncratic patients aged 6 months to 1 year with specific genetic background,eczema and wheezing under allergen test and comprehensive intervention via a randomized double-blind method.The onset of symptoms and measurement of immunological function were compared after 18 months.Results Serum IgG and IgA increased(all P＜0.05),wheezing and eczema attacks decreased significantly(all P＜0.01),sleep and emotion also improved significantly in the treatment group after 18 months(all P＜0.05).Milk and eggs were the most common allergen for infants and young children.Conclusion Idiosyncrasy and environmental factors were risk factors for allergic diseases.Early childhood was a critical period influencing the occurrence of allergic diseases in children.Early intervention could reduce the incidence of allergic diseases in children and improve the quality of life of idiosyncratic infants and young children.

Objective To explore the clinical effect and safety of high frequency oscillatory ventilation (HFOV) combined thoracic close drainage for the treatment of mechanical ventilated neonates with pneumothorax.Methods Twenty-two neonates were enrolled in this study,who needed mechanical ventilation diagnosed with neonatal pneumothorax and received treatment of HFOV combined thoracic close drainage from Jan.2012 and Jun.2014 in the People's Hospital of Dongguan.We recorded blood gas analysis and parameters of breathing machine before using HFOV and 2,12,24,48 hours after using HFOV respectively.Results There were significant differences between HFOV before use (0) and 2,12,24,48 hours after using HFOV in terms of blood pH value,arterial partial pressure of oxygen(PaO2),partial pressure of arterial carbon dioxide (PaCO2),oxygenation index (OI),the inspired oxygen concentration (FiO2),mean airway pressure (MAP) (F =6.606,17.760,8.387,17.242,25.185; P ＜ 0.05).Compared with before using HFOV combined thoracic close drainage,PaO2 was significantly increased from (51.25 ± 13.16) mmHg to (62.60 ± 15.95) mmHg.PaCO2 was significantly dropped from (63.57 ± 13.81) mmHg to (54.02 ± 11.58) mmHg and OI was dropped sharply from (16.57 ± 9.09) to (11.28 ± 4.67) at 2 hours after using HFOV combined thoracic close drainage (P ＜ 0.05).FiO2 significantly decreased from (0.76 ± 0.15) to (0.60 ± 0.13),as well as MAP from (9.91 ± 1.44) cm H2 Oto (8.50 ± 1.68) cm H2O.Furthermore,pH was significantly improved from (7.24 ± 0.15) to (7.34 ±0.10) at 12 hours later(P ＜0.05).PH,PaO2,PaCO2 were roughly back to normal at 48 hours after treatment.The main complications were intraventricular hemorrhage (2 cases),subarachnoid hemorrhage (2 cases),ventilator associated pneumonia (1 case) and pulmonary hemorrhage (1 case) (not during the time of HFOV treatment).Conclusion HFOV combined thoracic close drainage for the treatment of neonates with pneumothorax is safety and effective methods.
