Objective:To study the correlative clinical factors that causing hypophosphatemia in postoperative patients of general surgery.Methods:Serum phosphate levels of 101 patients of general surgery were monitored at the preoperative day,and the first,forth and seventh postoperative day.Influence factors of the serum phosphate levels were analysed.Results:The serum phosphate levels in patients elder than 55 years were lower than those younger than 55 years on the first and forth postoperative day(P

Objective To introduce a modified intraoral fixed appliance for maxillary protraction and to investigate the dentofacial changes of anterior crossbite after the therapy. Methods Twelve patients with anterior crossbite were treated with modified protraction therapy. The cephalometric analysis was used to evaluate the changes. Results After active treatment, the overjet correction was 6.55 mm. A point moved forward 2.6 mm. Pg dislocated backward 5.65mm with MP-FH increased 1.7?. Esthetics was greatly enhanced. Conclusion The modified maxillary protraction is recommended for easy fabrication, good retention, wearing comfortably and cleaning easily. Esthetics is greatly enhanced.

Background:Myopathy due to smooth muscle cells( SMC)abnormalities is involved in the pathogenesis of diabetic gastroparesis(DGP),however,the relationship between myopathy and advanced glycation end products(AGEs)is not fully clarified. Aims:To investigate the ultrastructural changes of gastric SMC in patients with diabetes mellitus( DM)and the relationship between expressions of contractile proteins and AGEs. Methods:Full-thickness gastric specimens from 30 gastric neoplasm patients undergoing gastrectomy from July 2012 to December 2012 at the First Affiliated Hospital with Nanjing Medical University were collected. Of them 15 patients had DM( DM group)and the other 15 patients without ( control group). Ultrastructure of SMC was observed by transmission electron microscopy. Expressions of three contractile proteins[ myosin heavy chains( MHC),α-actin and calponin]and Nε-carboxymethyllysine( CML),the key component of AGEs in gastric muscular layer were determined by Western blotting,and expressions of MHC,α-actin and calponin mRNA were determined by real-time PCR. Correlations of mRNA expressions of three contractile proteins with protein expression of CML were analyzed by Pearson correlation coefficient. Results:In DM group,significant ultrastructural changes were found in gastric SMC,including disruption of gap junction,swelling of mitochondria,occurring of lipofuscin in cytoplasm,increase in cell membrane alveolae,and thickening of basal lamina. Protein and mRNA expressions of muscular MHC,α-actin and calponin were significantly lower in DM group than in control group(P all ﹤0. 01),while protein expression of CML was significantly higher in DM group(P ﹤0. 01). In gastric muscular layer of DM group, negative correlations were found between expressions of MHC,calponin mRNA and CML protein(r= -0. 59,P=0. 02;r= -0. 63,P=0. 01),but no correlation was seen between α-actin mRNA and CML protein(r= -0. 49,P=0. 06). Conclusions:Disruption of SMC ultrastructure,decrease in contractile proteins and increase in AGEs are existed in gastric muscular layer of DM patients,and there is a negative correlation between contractile proteins and AGEs. These changes may cause impaired contractility of SMC,and subsequently lead to gastric motility disorders in diabetic patients.

Gastroesophageal reflux disease( GERD)is caused by dysfunction of lower esophageal sphincter( LES), which allows the contents of stomach and duodenum to reflux into esophagus. Currently,medical and surgical therapies are the main treatment for GERD,but patients need to take life-long acid suppression and the surgical treatment has the risks of potential side effects. Endolumenal therapy as a minimally invasive approach to GERD can safely and effectively relieve the symptoms of GERD,especially Stretta radiofrequency procedure,transoral noninvasive fundoplication( TIF ) and LinX reflux management system. This article reviewed the advances in study on endolumenal therapy for GERD.

Objective　In order to explore the prevalence of hypophosphatemia in postoperative patients of general surgery,as well as the time and dosage of phosphate replacement and its effects.Methods　To serum phosphate levels of 45 patients with phosphate replacement begun on the second postoperative day and 45 without replacement were monitored at the preoperative day,and the first,third,fifth and seventh postoperative day.Results　The incidence of hypophosphatemia was 91.1%(41/45) in cases without phosphate replacement.While it was 57.8%(26/45) in those with replacement.The serum phosphate concentrations in cases with phosphate replacement were higher than those without replacement on the third(P<0.001),fifth(P<0.05) and seventh(P<0.01) postoperative day.The Apache Ⅱ scores in cases with phosphate replacement decreased on the third postoperative days compared with those on the first day(P<0.001).Conclusion　The postoperative replacement of phosplates can avert the occurrence of hypophosphatemia and improve the Apache Ⅱ score.

Phosphatidylserine (PS) is a phospholipid that is abundant in eukaryotic plasma membranes,has crucial biological functions.Under cell apoptosis, cells can not generate enough ATP for energy and the concentration of cytoplasmic Ca 2 +increases, resulting in PS eversion.Apoptosis and the clearance of apoptotic cells are essential processes in animal development and homeostasis.For apoptotic cells to be cleared, they must display aneat me signal, most likely PS exposure, which prompts phagocytes to engulf the cells.PS is exposed by the action of scramblase on the cell's surface in biological processes such as apoptosis and platelet activation.Once exposed to the cell surface, PS acts as an eat me signal on dead cells, and creates a scaffold for blood-clotting factors on activated platelets.The molecular identities of the flippase and scramblase that work at plasma membranes have long eluded researchers.Indeed, their identity as well as the mechanism of the PS exposure to the cell surface has only recently been revealed.We describe how PS is exposed in activated platelets and in apoptotic cells, and discuss the clearance of apoptotic cells.
