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 To study the IgG antibodies on red cell surface in ABO and Rh-incompatible infants and to evaluate its predictive value for hemolysis. Methods From Nov. 2001 to Jul. 2002,50 full term newborn babies with ABO and Rh incompatibility hemolysis were admitted .They were divided into two groups according to the direct Coombs test(DCT): 38 cases with positive result and 12 cases were negative. Another 30 normal newborns were chosen as control group. Erythrocyte associated IgG,A and M were measured by a flow cytometry (FCM). Results the mean level of concentration of IgG antibodies in positive DCT group was (12.64?16.83)%,while (4.54?2.54)% in negative DCT group ( P 427.5 ?mol/L,IgG was elevated with the increased TSB level. There was a close relationship between the concentration of TSB and IgG ( r =0.678). Conclusion Measurement of erythrocyte surface antigen IgG assists the diagnosis of maternal-fetal incompatible hemolysis,especially when with a positive direct Coombs test result.

Objective: To study the inhibitory effect of VEGF antisense oligonucleotides (ASODN) on growth of Lewis lung cancer in C57BL/6 mice.Methods: Lewis lung cancer cells were cultured and implanted subcutaneously into 40 C57BL/6 mice, which were then divided into 4 groups: VEGF-ASODN treatment group, VEGF-SODN treatment group, BEGF-MODN treatment,and control group (normal saline). Mice in different groups were treated 24 hours after cell inoculation. The weight and volume of subcutaneous tumors was measured and the morphological changes of tumor cells was observed under microscope. VEGF protein and microvessel density were examined by immunohistochemistry.Partial tumor tissues were kept in liguid nitrogon.Results: The average tumor weights of the control, VEGF-ASODN, VEGF-SODN and VEGF-MODN groups were (7.33?0.71)g, (4.56?0.38) g, (7.59?0.32) g, and (7.62?0.39) g, respectively. The inhibition rates of tumor growth in VEGF-ASODN, VEGF-SODN and VEGF-MODN group were 43.8%, 5.5% and 3.1%, respectively. VEGF-ASPODN obviously inhibited the tumor cell growth and decelerated the tumor cell proliferation. Immunohistochemistry results showed that the expression of VEGF in ASODN group was remarkly lower than those in SODN group, MODN group and control group (P

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.
