Objective To observe the clinical efficacy of esomeprazole combined with trimebutine maleate in the treatment of reflux esophagitis patients without helicobacter pylori infection.Methods 78 patients with reflux esophagitis were randomly divided into two groups,46 patients in study group and 32 patients in control group.30 minutes before the breakfast,all the patients took Nexium 20mg,twice a day.The study group was given trimebutine maleate 200mg,thrice a day additionally.The treatment course was 4 weeks.The effect and the result of gastroendoscopy were observed.Results The average time of clinical symptoms disappeared in study group was (10.51 ± 2.43) days,which was significantly shorter than (12.31 ± 3.17) days of the control group (t-2.84,P ＜ 0.01).The total effective rate of the study group was 97.83％,which was significantly higher than 81.25％ of the control group (x2 =4.48,P ＜ 0.05).Conclusion Esomeprazole combined with trimebutine maleate in the treatment of reflux esophagitis without helicobacter pylori infection can promote gastric emptying,prevent reflux,control esophageal inflammation and promote ulcer healing effectively.

BACKGROUND:The effect of placenta-derived growth factor(PLGF)on promoting vascular regeneration remains uncertain.In studies of models with PLGF deletion,PLGF has been considered to play critical role in inducing angiogenesis.OBJECTIVE:To summarize the research advances in effect of PLGF and its receptor in vascular regeneration and ischemic cerebral disease.METHODS:A computer-based online search of Pubmed and CNKl was performed for relevant articles published between 1990 and 2009 with key words of"PLGF"in Chinese and"PLGF angiogensis"Articles related with biological characteristics of PLGF and its roles in vascular regeneration and articles related with angiogenesis and PLGF expression after cerebral ischemia were selected.Repetitive articles were excludedRESULTS AND CONCLUSION:The role of PLGF and its receptor in vascular regeneration,mechanism of PLGF and its receptor to promote angiogenesis,vascular endothelial growth factor A,and the expression of PLGF and its receptor in brain after cerebral ischemia were introduced.PLGF can promote pathological angiogenesis,arteriogenesis,branch formation and hemopoietic progenitor cell mobilization.PLGF and its receptor play an important role in the angiogenesis of ischemic cerebral disease and display a good clinical prospect in the treatment of ischemic cerebral disease However,the specific role and mechanism require further study.

Objective To preliminary study clinical efficacy and toxicity of endostatin (ES) combined radiotherapy and chemotherapy in advanced non-small cell lung cancer (NSCLC),and evaluate its effectiveness and safety.Methods We retrospectively reviewed 64 patients with Ⅲ B-Ⅳ stage NSCLC of Harbin Medical University Cancer Hospital from February 2009 to February 2012.The patients were divided into two groups:chemoradiotherapy group,39 patients and ES add chemoradiotherapy group,25 patients.The short-term effect,the total efficiency,median survival time,progression-free survival time and disease-free survival time were compared.Results The total effective rate of chemoradiotherapy group was 76.9％,while the total effective rate of ES add chemotherapy group was 84.0％ (x2 =0.47,P =0.492).Chemoradiotherapy group,compared to ES add chemotherapy group,the median survival time,median progression-free survival time,median disease-free survival time were 11.52 months vs 16.51 months (x2 =3.74,P =0.042),7.32 months vs 10.37 months (x2 =5.32,P =0.025) and 5.21 months vs 7.57 months (x2 =4.56,P =0.035) respectively.The mainly adverse drug reactions were hematologic toxicity and gastrointestinal reactions,but there were no significant differences between the two groups; radiotherapy side effects mainly showed the grade 1 to 2 radiationinduced lung injury and radiation esophagitis (chemotherapy group had one case of grade 3 radiation-induced lung injury),but also had no significant differences between the two groups.Conclusion ES combined chemoradiotherapy can achieve a better short-term clinical efficacy without increasing adverse effects of radiotherapy or chemotherapy in advanced non-small cell lung cancer.

AIM: To investigate the effect of intravitreal injection of anti-vascular endothelial growth factor (VEGF) drug Bevacizumab on connective tissue growth factor(CTGF) and pigment epithelium derived factor (PEDF) in proliferative membranes in patients with proliferative diabetic retinopathy (PDR).METHODS: From January 2015 to December 2016, 117 patients (126 eyes) with PDR were analyzed using the case-control study.The selected cases were randomly divided into two groups, respectively, Group A of 60 cases (63 eyes) and Group B of 57 cases (63 eyes).The Group A was treated with vitrectomy alone, while the Group B received intravitreal injection of 0.05mL/1.25mg bevacizumab before vitrectomy.The peeled epiretinal membranes in patients were stained and then the histopathological changes were observed for primitive cells and angiogenesis, the expression of CTGF and PEDF were tested.RESULTS: The expression of CTGF and PEDF in the proliferative membrane of the two groups were expressed in the cytoplasm.The Group A showed positive expression in 38 cases, the positive rate was 60.3%.Compared with Group A, the positive expression rate of CTGF in Group B (92.1%) was significantly higher (P<0.05).The positive expression rates of PEDF in the two groups were 90.5% and 95.2% respectively, and there was no significant difference between the two groups (P>0.05).CONCLUSION: In patients with PDR after intravitreal injection of bevacizumab, the retinal neovascularization is significantly reduced, which is conducive to vitrectomy.The positive expression rate of CTGF significantly increased in patients with PDR after intravitreal injection of bevacizumab, but there was no significant change in the expression of PEDF in the anterior membrane.

AIM: To study the effect of intravitreal injection of anti-vascular endothelial growth factor (VEGF) on best corrected visual acuity (BCVA) and multifocal-electroretinogram (mfERG) before and after treatment for choroidal neovascular disease.METHODS: A total of 264 patients (332 eyes) with macular neovascularization (MCNV) and idiopathic choroidal neovascular disease (ICNV) who underwent pathologic myopia from January 2015 to January 2017 were enrolled in this study.Intraocular pressure and BCVA, fundus using 90D front mirror and slit lamp detection, and the fundus photograph, OCT, ICGA and FFA angiography, mfERG detection were taken.One month after the drug, 1mo after the final treatment, we recorded BCVA, intraocular pressure and mfERG and so on.RESULTS: Ranibizumab was injected into the 254 eyes, and 78 eyes were injected with conbercept.There were 37 eyes injected once, 147 eyes were injected twice, 72 eyes were injected 3 times, 57 eyes were injected 4 times, 19 eyes 5 times.There were no significant differences on intraocular pressure between the two groups (P>0.05).The BCVA before treatment was significantly different compared with those 1mo after treatment and 1mo after the final treatment (P>0.05).The amplitude of Ring1, Ring2 and Ring4 increased after treatment, the difference was statistically significant.(P<0.05).The amplitude of Ring3 and Ring5 increased at 1mo after final treatment(P<0.05).CONCLUSION:Intravitreal injection of anti-VEGF drugs has a significant effect on BCVA and mf ERG in patients with choroidal neovascular disease and is safe.

OBJECTIVETo study effects of autogenous femoral head bone grafting combined with total hip replacement for the treatment of old center dislocation of hip joint, and to evaluate the superiority of acetabular defect reconstruction with autogenous bone.

METHODSFrom March 2008 to December 2013, 16 patients (16 hips) with old center dislocation of hip joint were treated with autologous bone graft combined with total hip replacement. There were 11 males and 5 females, ranging in age from 41 to 72 years old, with an average of 56.3 years old. The duration of the disease ranged from 3.6 to 37.2 years. Twelve patients had injuries caused by traffic accidents and 4 patients were caused by falling down. The hip joint pain at the first month after operation, Harris score and hip joint movement of all patients were observed by using electronic case follow-up system.

RESULTSAll the patients were followed up, and the duration ranged from 11 to 78 months, with an average of 27.3 months. The postoperative hip joint movement of (56.2±23.4)° VAS 86.3±7.2 and Harris score 32.6±12.6 were all better than preoperative (181.8±17.6)°, 11.1±2.6 and 86.3±7.2. The joint pain was reduced and the function limitation was improved after operation, and the prosthesis position was good.

CONCLUSIONWhen the autologous femoral head bone grafting combined with total hip arthroplasty is used to treat old hip central dislocation, the initial and long-term stability of acetabular bone grafting is good, and the technique can avoid allogeneic bone complications, bone source rationally and reduce the economic burden of patients.

BACKGROUND:At present, it is controversial to choose methotrexate therapy alone or triple therapy in the treatment of rheumatoid arthritis.
OBJECTIVE:To systemical y evaluate the efficacy and safety of methotrexate therapy and methopterin+hydroxychloroquine+sulfasalazine triple therapy in the treatment of rheumatoid arthritis.
METHODS:Computer retrieval was performed on the Cochrane library, PubMed, EMBASE NRR (http://www.updatesoftware.com/National), CCT (http://www.control ed-trails.com) and the Chinese biomedical literature database. Manual retrieval was performed on Chinese major orthopedic journals. Randomized control ed trials of methotrexate therapy alone and methopterin+hydroxychloroquine+sulfasalazine triple therapy treatment for rheumatoid arthritis were col ected. Methodological quality of the included studies was evaluated. The statistical software Revman 5.0 provided by the Cochrane col aboration was used.
RESULTS AND CONCLUSION: A total of four literatures in a randomized control ed trial, a total of 297 cases were included;the methodological quality was al class B. Meta-analysis results showed that blood sedimentation improvements were larger in methotrexate therapy alone than in the triple therapy [mean difference=7.01, 95%confidence interval (CI) (2.82, 11.19), P=0.001). Improvements of joints were better in triple therapy than that in single therapy [OR=0.62, 95%CI (0.41, 0.95), P=0.03). There was no significant difference in adverse events. Meta analysis could not be done in ACR, because literature did not provide detailed data. Compared with the triple therapy treatment, methotrexate therapy alone obviously reduced the sedimentation of rheumatoid arthritis in adults, but in terms of joint function improvement, triple therapy was superior to methotrexate therapy alone. Moreover, on the adverse event, there was no significant difference between the two groups. Because this system evaluation included a less number of cases, it stil needs strict large-sample randomized control ed studies to increase the strength of the evidence.
