Objective To observe the therapeutic effect of hyper-laser irradiation combined with acupuncture for the treatment of temporomandibular joint disturbance syndrome(TMJDS).Methods Sixty TMJDS patients were equally randomized into two groups: the treatment group was given hyper-laser irradiation combined with acupuncture,and the control group given acupuncture alone.The treatment lasted 10 days.After treatment,the improvement of symptoms and signs in both groups was evaluated.Results The total effective rate was 93.3% in the treatment group and 80.0% in the control group,the therapeutic effect in the treatment group being superior to that in the control group(P

Objective To evaluate the expression of Integrin α2β1 in serum of osteosarcoma patients and to investigate the effect of Integrin α2β1 on metastasis of osteosarcoma. Methods Sandwich enzymelinked immunosorbent assay was applied to test Integrin α2β1 in serum of 26 healthy controls (male 16, female 10; age 18-32, average age 23.54±3.82) and 43 osteosarcoma patients (male 28, female 15;age 8-47,average age 18.42±9.10)before and after the surgery and the chemotherapy. The patients included osteoprogenitor cells type in 24 cases, fibroblast type in 9 cases, chondroblast type in 7 cases, and other types in 3cases; with Enneking stage ⅡA in 13 cases, stage ⅡB in 26 cases, stage Ⅲ in 4 cases. Among them, 22 patients receive the neo-adjuvant chemotherapy. After that, we compared the data of different groups. At the same time, in accordance with tumor size, position, clinical stage, histology grade and metastasis situation to categorize groups compared among the groups of serum Integrin α2β1 differences in order to explore its relationship with patients' prognosis and metastasis. Results The Integrin α2β1 of osteosarcoma patients in blood before the surgery was expressed highly. It was significantly higher than the control group. The expression before surgery had significant correlation with osteosarcoma Enneking clinical stages, tumor size and metastasis. And it was independent of tumor position and Dahlin histology grade. The expression of Integrin α2β1 in blood of the osteosarcoma patients after limb salvage surgery decreased significantly. And the expression of Integrin α2β1 in blood of patients receiving new adjuvant chemotherapy was significant differences before and after the chemotherapy. Conclusion The expression of Integrin α2β1 has positive correlation with the occurrence, development and metastasis of the osteosarcoma. It is probably a new biological indicator for diagnosis and estimating prognosis of osteosarcoma. Simultaneously surgery and new adjuvant chemotherapy are still effective methods to treat osteosarcoma.

The occurrence and development of solid tumor is a multi-factor,multi-step and multi-gene interactive process.The generation of micro vasculature of solid tumor,as well as the interaction between tumor and micro-environment,decides the tumor's biological characteristics of growth,recurrence,invasion and metastasis.Reasonable application of anti-angiogenesis therapy enables the normalization of tumor vascular system to enhance the efficiency of chemotherapy and radiation treatment and prolong survival time in patients.

Neoadjuvant chemotherapy evaluation methods are becoming the focus of osteosarcoma chemotherapy research in recent years.This paper updates the evaluation methods of osteosarcoma neoadjuvant chemotherapy in such aspects as pathological histology,imaging studies,and the examination of molecular levels.

Objective To investigate the association between FcγRIIA H/H131 genotype and pneumonia through a comprehensive meta‐analysis .Methods Databases including PubMed ,Embase ,and China National Knowledge Infrastructure (CNKI) were searched with such terms as “FcgammaRIIa” ,“FCGR2A” ,“Fcgamma receptor IIA” ,“CD32” and“pneumonia” ,“polymorphism” ,“variant” ,“genotype” ,“allotype” ,as well as“pneumonia”and“polymorphism”in Chinese to identify relevant studies .Two reviewers independently extracted the data .Crude odds ratios (ORs) and corresponding 95%confidence intervals (CIs) were estimated .Heterogeneity across studies and publication bias were evaluated and sensitivity analyses were performed .Results Six case‐control studies were finally included in this analysis .The results indicated an association between FcγRIIA H/H131 genotype and pneumonia susceptibility (OR 1 .67 , 95% CI 1 .11‐2 .51 ) , but no significant association with R/R genotype(OR 1 .09 ,95% CI 0 .85‐1 .40) or H/R genotype(OR 0 .81 ,95% CI 0 .60‐1 .19) . Statistically significant heterogeneity was found during data pooling (I2 was 75 .4 % ,51 .8% and 71 .9% ) .Sensitivity analyses further indicated the reliability of the study .Egger′s and Begg′s tests identified publication bias in R/R genotype ,but not in H/H or H/R genotype .Conclusions We preliminarily find an association between FcγRIIA H/H131 genotype and pneumonia susceptibility .

Objective: Changes in the ?2 integrin of adhesion molecules between cells are closely associated with the invasion and migration of tumor cells.This study aimed at the effect of anti-?2 integrin on the invasion and migration of osteosarcoma MG63 cells. Methods: The osteosarcoma MG63 cell line was cultured in the DMEM medium.The effect of the anti-?2 integrin monoclonal antibody on the migration and invasion of tumor cells were measured by scratch assay and Transwell assay.The migration and invasion cells were stained by Crystal violet staining and counted under the hundredfold microscope.Results: Compared with the control group,the migration and invasion abilities of the MG63 cells were significantly decreased in the anti-?2 treatment groups.Conclusion: Anti-?2 integrin may inhibit the migration and invasion of osteosarcoma cells.

Objective To explore the clinical characteristics and treatment of infants with cytomegalovirus(CMV)pneumonia.Methods The clinical and auxiliary examination data of 24 patients with CMV pneumonia,which were diagnosed by detection of serum CMV-IgM used enzyme immunodot technique.All patients were treated with ganciclovir (GCV).Results The most common clinical manifestations of CMV pneumonia were cough,breathlessness,fever,crackles and wheezing rale.Chest X-ray findings predominately revealed increased and thickened bilateral lung markings and patchy areas of increased opacity in both lungs.Sixteen cases were cured,8 cases improved.Conclusions Clinical manifestations of infant CMV pneumonia lack specificity.The presence of serum CMV-IgM antibody is a laboratory diagnostic evidence.GCV is the best choice of drug in treatment of infants with CMV pneumonia.

Objective To search for the reasons of high positive rate of amotile bacteria and the diagnosis of septicemia in new-born Methods The blood was drawn from the different site of the new-born with septicemia and carricd out blood culture. The drug sensitivity test had been done by the method of paper stripdiffusion. The plasmids of bacteria were extracted rapidly by medified Birnboim method and the plasmid analyss was carried out. The plasmids's DNA of 35 epidemic strain was cut off by both restriction enzyme of Hind Ⅲ and EcoR Ⅰ. The outer membrane protein (OMP) was determined by SDS-polyacrylamide gel electrophoresis.Results There are 51 patients with positive blood culture amotile bacterium,of them, pollution; 35 cases (68．6%), septicemia: only 16 cases (31．4%),54．8% (57/104) strains bacteria have drug resistance to more of 12 drugs. 87．3% (165/189) strains bacteria have plasmids. They are cut off as 6 DNA fragments (1．9,2,4,5, 8．5 and 18Kb) by Hind Ⅲ restrietion enzyme. and as 5 DNA fragments (2,2．6,3．2, 6．3 and 22 Kb) by EcoR Ⅰrestrietion enzyme, it is showed that they come from a same clone. The epidemic strain include 10 slips OMP, but non-epidemic strain have 11 slip OMP, increase a 25Kd belt. The amotile bacteria with above-mentioned plasmid spectrum, restriction enzyme spectrum and OMP spectrum are only seen in the air, therapeutic dish and syringe needle.Conclusion The pollution is an important reason of amotile bactorium high positiye rate in new-born.Diagnosing septicemia should depend on bacteria culture, plasmid analysis restriction enzyme analysis of plasmid DNA, oMP determination and combining medical history and clinical manifestation.

Objective To observe the impact of Aspergillus fumigatus conidia on the early apoptosis of alveolar epithelial cells.Methods A549 cells was first stimulated with tumor necrosis factor-α(TNF-α)or staurosporine (STS)to induce cell apoptosis,and then co-cultured with Aspergillus fumigatus conidia of three different concentrations (5 × 10 5 ,5 × 10 6 ,5 × 10 7 )simultaneously.The changes of the apoptosis rate of A549 cells were detected by flow cytometry.Results The early apoptosis of A549 cells was increased markedly after stimulated with TNF-α ([14.94 ± 0.82 ]% vs [3.26 ± 0.74]%,χ2 =9.18,P <0.05)and STS ([18.10±1 .00]% vs [3.26±0.74]%,χ2 =12.32,P <0.05). When Aspergillus fumigatus conidia of different concentrations were added,the apoptosis rate was decreased (χ2 =31 .23,P <0.05 ).The early apoptosis of A549 cells was negatively correlated with the concentration of Aspergillus fumigatus conidia (rTNF = - 0.92,r STS = - 0.94,both P < 0.05 ). Conclusion Aspergillus fumigatus conidia inhibits the early apoptosis of A549 cells induced by TNF-αor STS and the inhibit effect increases with the concentration of Aspergillus fumigatus conidia.

Objective To analyze the relative factors for the prognosis in elderly patients with stroke,and provide theoretical basis for improving prognosis.Methods 188 elderly patients with stroke were treated in our department from Jan.2011 to Nov.2013,and clinical data was analyzed.The prognosis and relative risk factors for stroke were statistically analyzed.Results 99 cases had good prognosis,89 cases had poor prognosis,and the recovery rate were 52.7％ (99/188) and 47.3％ (89/188) respectively.The age was older in group of good prognosis than in group of poor proghosis (t=1.7930,P＜0.05).Univariate analysis showed that the age,position of cerebral infarction,size of lesions,hypertension,diabetes,drinking and smoking were associated with the prognosis of stroke (t=1.7930,x2 =8.6473,15.046,13.1334,4.1536,5.7004,5.9043,respectively,all P＜0.05),while the prognosis was not associated with gender,a family history of stroke,hyperlipidemia and heart disease.Multivariate logistic regression analyses revealed the prognosis of stroke was related with risk factors of age (OR=1.072),size of the lesion (OR=3.481),hypertension (OR=2.034),diabetes (OR=1.631) and smoking (OR=3.144).Conclusions It is beneficial to the prognosis of patients with stroke to stop bad habits and to treat hypertension and diabetes actively.
