Objective To investigate the clinical efficacy of intravitreal ranibizumab injection combined with complex trabeculectomy in treatment of neovascular glaucoma. Methods Totally 38 patients(38 eyes) of neovascular glaucoma were divided into two groups of 19 cases in each randomly. Patients in treatment group were treateded with complex trabeculectomy after intravitreal injection 0. 05 mL ( 0.5 mg ) ranibizumab 4 - 7 days. Patients in control group were treateded with cyclocryotherapy. Visual acuity, intraocular pressure, iris neovascularization and complications were observed. Results The average intraocular pressure of preoperation and postoperation 1 month in treatment group were (6.5±1.7) kPa and (2.1±1.2) kPa.The difference of intraocular pressure before and after operation was significant. The average preoperative and postoperative intraocular pressure in control group were (6.7±1.9) kPa and (2.5±1.2) kPa . The postoprative intraocular pressure of treatment group was lower than that of control group, the difference was statistically significant( P< 0.05). Visual acuity and operative reaction after operation in treatment group were superior to those in control group. Conclusion Intravitreal injection of ranibizumab combined with complex trabeculectomy in treatment of neovascular glaucoma is safe and effective and worth in clinical application.

Eukaryotic elongation factor 2 kinase (eEF2K) is well known as a Ca2+/calmodulin (CaM)-dependent kinase. eEF2K catalyzes the phosphorylation of eEF2 and subsequently inactivates eEF2 by impairing its ability to bind to the ribosome, thereby negatively modulates protein synthesis. The high expression of eEF2K has been found recently in several types of malignancies. As participating in the progress of tumor, eEF2K emerges a potential target for future cancer therapy. The relationship between eEF2K and tumor, and the latest progress of eEF2K inhibitors were summarized in this article.

Objective To investigate the role of serotonin transporter (SERT) in pathogenesis of abdominal pain in irritable bowel syndrome (IBS). Methods Neonatal SD rats were divided into control group and IBS abdominal pain model group which was established by colorectal distension.The colon, nucleus raphes dorsalis (NRD) and prefrontal cortex (FC) tissues were harvested when all rats grew into adults. Expressions of SERT and 5-HT were determined by real-time PCR and immunohistochemistry. Results The expression of SERT mRNA in colon, NRD and FC tissues in model and control group were 13.95±2.05 vs 8.65±1.33, 52.69±22.59 vs 13.82±5.71 and0.48±0.17 vs 0.17±0.14, respectively, with significant differences (all P values ＜0.05). The protein expression of SERT in colon and NRD,but not FC tissues,decreased in model group compared with control group (13.19±3.82 vs 21.35±4.49,2.47±0.44 vs 4.55±0.92, respectively, P＜0.05).Meanwhile, in comparison with control group, the expression of 5-HT in colon was significantly increased in model group (5.56±0.48 vs 2.68±0.22), but decreased in NRD and FC tissues (3.75±0.43 vs 7.46±0.72, 5.07 ± 0.80 vs 7.97 ±1.10, respectively, P＜0.05). Conclusions Low expression of SERT in brain and colon may attribute to the pathogenesis of abdominal pain in IBS.

Objective To evaluate the energy metabolism of normal muscle in different age group.Methods Noninvasive 31P-MRS was acquired from quadriceps muscles in healthy people including 10 adults and 6 juvenile.Peak areas were standardized for longitudinal saturation and coil inhomogeneity.The concentration of phosphomonoesterase(PME),inorganic phosphate(Pi),phosphodiesterase(PDE),phosphocreatine(CrP)and adenosine triphosphate(ATP)was determined from spectra.Concentrations of adenosine diphosphate(ADP)and phosphorylation potential(PP)were calculated from the biochemistry reaction equilibrium.Enzymatically active magnesium ATP complex Mg-ATP and pH value were determined from relative chemical shift.Results Normal muscle had prominent high energy phosphate peaks,the mean concentration of CP and ATP was 24.76 and 18.38 mmol/kg in adults,25.52 and 21.36 mmol/kg in young subject.In comparison with adult group,young subjects had lower PDE and higher ATP values.pH value,magnesium ATP and total magnesium were higher in young subjects too.Pi,CP,ADP,PP,free Mg2+ and free ATP concentration were similar in both group.Conclusion High energy compounds were slightly higher in juvenile subjects.31P-MRS is a noninvasive technique to evaluate energy metabolism in different age group.

Objective To explore the efficacy and prognostic factors of postoperative intensity?modulated radiotherapy ( IMRT) with or without chemotherapy in rectal cancer. Methods A retrospective analysis was performed on the clinical data of 218 patients with rectal cancer, who underwent postoperative IMRT in our hospital from January 2009 to December 2013. The Kaplan?Meier method was used to calculate survival rate;the log?rank test was used for survival difference analysis and univariate prognostic analysis;the Cox regression model was used for multivariate prognostic analysis. Results The follow?up rate was 97. 7%. The 1?and 3?year overall survival rates were 90. 8% and 75. 2%, respectively, the 1?and 3?year disease?free survival rates were 85. 3% and 70. 5%, respectively, and the 1?and 3?year locoregional recurrence?free survival rates were 96. 7% and 88. 1%, respectively. The incidence of grade 3?4 acute adverse reactions was 28. 4%, mainly manifested as leukopenia ( 13. 8%) and diarrhea ( 11. 0%) . Univariate prognostic analysis showed that preoperative carcinoembryonic antigen ( CEA) and CA199 levels, maximum tumor diameter, tumor location, degree of differentiation, depth of tumor invasion, number of lymph node metastases, TNM stage, perineural invasion, surgical procedure, total mesorectal excision, preoperative bowel obstruction, and preoperative anemia were the predictors of survival ( P=0. 006, 0. 000, 0. 000, 0. 017, 0. 000, 0. 016, 0. 000,0. 011,0. 001,0. 006,0. 037 and 0. 010) . Multivariate prognostic analysis showed that preoperative CEA level, tumor location, TNM stage, preoperative bowel obstruction, and preoperative anemia were the predictors of survival ( P=0. 000,0. 000,0. 000,0. 001 and 0. 001) . Conclusions Postoperative IMRT with or without chemotherapy is an effective method for rectal cancer with mild adverse reactions and high compliance. Preoperative CEA level, tumor position, TNM stage, preoperative bowel obstruction, and preoperative anemia are independent prognostic factors for the overall survival.

Serum triglyceride ( TG ) , total cholesterol ( TC ) , low density lipoprotein cholesterol ( LDL-C) , high density lipoprotein cholesterol ( HDL-C) , uric acid ( UA) levels and fasting blood glucose ( FBG) were measured in 67 patients with chronic spontaneous urticaria ( CSU ) and 66 healthy subjects ( controls).Results showed that the rates of increased serum TG and FBG levels in CSU patients were higher than those in controls ( 19% vs.6%,χ2 =5.309, P <0.05; 12% vs.1%,χ2 =4.194, P <0.05, respectively);however, there were no significant differences in abnormal rate of TC(7%vs.3%) , LDL-C (4%vs.1%), HDL-C(6%vs.3%)and UA(6%vs.1%) between CSU patients and healthy controls(all P>0.05).The rate of rising FBG in CSU patients accompanied by angioedema(4/9)was higher than that in CSU patients without angioedema(7%,χ2 =7.181,P<0.05).

A total of 120 medical students were surveyed to investigate the current status of communication between medical students and old patients and the awareness of medical laws. The questionnaire shows many students don't have enough knowledge of communication skills and medical laws. Furthermore, the most important reason of the medical disputes is the lack of communication between doctors and patients so the cultivation of communication skills and legal knowledge should be strengthened.

In this study, the colonization and distribution of Helicobacter pylori (Hp) in patients with chronic gastric diseases were investigated and the relationship between the periodontal initial treatment and presence of Hp in oral cavity was examined to better understand the connection between Hp infection and chronic diseases. Primers for PCR amplification were designed according to ureC gene and cagA genes of Hp. Specimens were harvested from different sites of 96 patients with chronic gastric diseases and the specimens of dental plaques, gargles and dorsal mucosa were tested for Hp. The 96 patients were treated by bismuth triple therapy and among them, 52 subjects were additionally given periodontal initial therapy. The eradication rate of gastric Hp and oral Hp detection rate were determined 4 weeks and 1 year after the treatment. The results showed that the detection rates of oral specimens were in the order of dental plaques (82.3%), gargles (51.1%) and scrapings of dorsal mucosa of tongue (37.5%). One year after bismuth triple therapy or the triple therapy in combination with periodontal initial treatment, the eradication rate of gastric Hp was significantly higher in the combination treatment group than in group treated by the triple therapy alone (62.8% vs. 32.4%, P<0. 05). Moreover, the Hp detection rate was significantly lower in the combination group than in the group treated only with the triple therapy. We are led to conclude that Hp is present at various parts of oral cavity, oral Hp might be an important source of gastric Hp and the triple therapy plus periodontal initial treatment can enhance the long-term eradication rate of gastric Hp in patient with both chronic gastric diseases and chronic periodontitis.
