Objective To observe the therapeutic effects of balloon dilatation with ice water and room temperature water on cricopharyngeal achalasia after brainstem stroke.Methods Forty dysphagic patients with cricopharyngeal achalasia after brainstem stroke were recruited.Twenty patients assigned to experimental group were treated by balloon dilatation with ice water and low frequency elecrtrical stimulation.Twenty patients assigned to control group were treated by balloon dilatation with room temperature water and low frequency electrical stimulation.Results After treatment,36 out of the 40 patients of the two groups could eat pasty food independently without choking.Videofluoroscopic swallowing study (VFSS) showed that the cricopharyngeal sphincter relaxed and the foods passed successfully when swallowing bolus,and no aspiration happened.In comparison,the level of cricopharyngeal opening,the number of patients with nasogastric tube remained and eating normally,and the scores of functional oral intake scale (FOIS) between the two groups showed no significant difference (P ＞ 0.05).The average treatment sessions,average hospitalization days and average treatment cost in treatment group were significantly less than those in the control group(P ＜0.05).Conclusion Cricopharyngeal achalasia can be treated effectively by balloon dilatation with ice water or with room temperature water combined with low frequency electrical stimulation,but treatment course of balloon dilatation with ice water were significantly shorter than that of balloon dilatation with room temperature water.

Objective To reasonably provide data basis of the expense standard for diagnosis related groups(DRGs)of respiratory system disease.Methods Use the first-page data of the medical records of 19,285 respiratory inpatients of a hospital.Use the Chi-squared Automatic Interaction Detector in the decision tree model to establish the inpatient case mix plan of respiratory disease inpatients.Then evaluate the model effectiveness with the variance reduction Results Expense median of the respiratory disease inpatients is 1603.97 yuan,averaging 2806.03 yuan,and the discretion degree is high.Proportion of surgical operations in respiratory disease is 3.89％,less than the others.Age is an important factor of respiratory disease for their hospitalization costs.Classification nodes of respiratory diseases are in turn the first discharge diagnosis,age,and secondary diagnosis.Patients were divided into 5 categories and 29 disease diagnosis related groups by such nodes.Conclusion Appropriate discharge diagnosis is the basis for building diagnosis related groups.Such variables as disease severity related variables as age and secondary diagnosis should serve as classification variables for respiratory system diseases.

OBJECTIVETo investigate the effects of prostate stromal cells from different zones of normal prostate tissue on the growth of prostate cancer cells and their action mechanisms.

METHODSWe extracted stromal cells in the fresh normal prostatic tissue derived from the peripheral zone (PZ) or transitional zone (TZ), amplified them in vitro, and used the supernatants of the cells as conditioned media to culture hormone-resistant prostate cancer DU145 cells. We measured the growth curve of the tumor cells using the CCK8 method, determined the number and viability of the cells by trypan blue staining, evaluated their invasiveness by scratch test, and detected the effects of the stromal cells on the key enzymes in the glycolysis of the tumor cells by Western blot.

RESULTSThe conditioned medium with the PZ-derived stromal cells promoted, while that with the TZ-derived stromal cells inhibited the growth of the tumor cells. The former significantly increased, while the latter markedly decreased the expressions of the key enzymes hexokinase 2 (HK-2), pyruvate kinase 2 (PKM-2), lactate dehydrogenase (LDHA), and pyruvate dehydrogenase (PDH) in the glycolysis of the tumor cells.

CONCLUSIONProstate stromal cells from different zones exert different influences on the growth of tumor cells, which may be associated with their different effects on the glycolysis of tumor cells.

Objective To explore the effect of the transtheoretical model of health behavior change on initial insulin injection in elderly patients with type 2 diabetes mellitus. Methods Thirty elderly patients with type 2 diabetes, receiving traditional training of insulin injection , were recruited as control group ( n = 30 ) between December 2013 and March 2014 . Another 30 elderly patients with type 2 diabetes, who received an education program based on the transtheoretical model of health behavior change for insulin injection training ( 30 minutes for each time and 4 times in total ) , were recruited as experiment group ( n=30 ) between April 2014 and July 2014. The knowledge of insulin injection and the operational skills in the two groups were compared between the two groups. Result Both the knowledge and operational skills at insulin injection in the experiment group were significantly better than those in the control group (P<0.01). Conclusion The transtheoretical model of health behavior change can be significant for improving the operational skills at insulin injection and therefore it can be effective in controling of blood sugar.

[ ABSTRACT] AIM: To investigate the effect of miR-496 over-expression on the growth and metastasis of colon cancer cells and its molecular mechanism .METHODS:The proteins interacting with miR-496 were screened by bioinfor-matic method.The levels of miR-496, CTNNB1 mRNA and β-catenin protein in colon cancer cell lines , HT29, HCT116 and SW480, and normal colonic epithelial cell line NCM 460 were detected by real-time PCR and Western blot .HT29, HCT116 and SW480 cells were transfected with miR-496 mimics using Lipofectamine 2000 and named as HT29-miR-496 mimics, HCT116-miR-496 mimics and SW480-miR-496 mimics cells, respectively, and the cells transfected with the scramble served as negative control .The cell viability, lactate dehydrogenase (LDH) leakage, and colony formation and metastatic abilities were determined by MTT assay , LDH assay, colony formation assay and Transwell method , respective-ly.The promoter activity of miR-496 was measured using luciferase reporter gene assay .The protein levels of β-catenin, eukaryotic translation initiation factor 4E-binding protein 1 (4E-BP1), p-4E-BP1, low-density lipoprotein receptor-related protein 6(LRP6), p-LRP6, MMP-7, MMP-9, MMP-13 and TIMP-2 were monitored by Western blot.RESULTS:Endog-enous miR-406 interacted with β-catenin was found in the colon cancer cells .Low miR-496 expression in the HT29, HCT116 and SW480 cells and high miR-496 expression in NCM460 cells were detected.In contrast, high β-catenin ex-pression was found in the HT29, HCT116 and SW480 cells and low β-catenin expression was observed in the NCM460 cells.Compared with control group , the cell viability, colony formation rate and the number of metastatic cells remarkably decreased in the HT29-miR-496 mimics, HCT116-miR-496 mimics and SW480-miR-496 mimic cells (P<0.05).The promoter activity of miR-496 was significantly increased in colon cancer cells transfected with miR-496 mimics, and was 1.75, 2.04 and 1.61 times as high as control group .miR-496 over-expression inhibited β-catenin levels, and p-4E-BP1 and p-LRP6 protein levels were also reduced .siRNA-or over-expressed miR-496-mediated β-catenin down-regulation in-hibited MMP-7 and MMP-9 expression , but promoted TIMP-2 expression .CONCLUSION:The expression level of miR-496 in the colon cancer cells is low , but in the normal colonic epithelial cells is high .miR-496 over-expression inhibits the protein levels of MMP-7 and MMP-9, and promotes the protein expression of TIMP-2 via inhibiting Wnt/β-catenin path-way, thus suppressing malignant phenotype in the colon cancer cells .

Objective To investigate the effectiveness of glucocorticoids in the treatment of granulomatous lobular mastitis (GLM), and to discuss the optimal stage to add glucocorticoids during the treatment. Methods Twenty-four patients having received the core needle biopsy were involved. Ten cases with the explicit pathological diagnosis received the glucocorticoids therapy following the subtotal excision after remission. Pathological diagnoses of the rest 14 patients were undefined. For these 14 patients, simple partial excisions were given and the postoperative pathological diagnoses were presented as the GLM. Of all the 14 patients who accepted the surgical treatment firstly, 8 patients received the postoperative glucocorticoids adjuvant therapy. For the rest 6 patients, steroid hormone therapy was not used after surgery, and they were followed up postoperatively. All patients' clinical and pathological information were collected and analyzed. Results All patients were followed up for 6-36 months (average 18) by the outpatient service. Of all the 10 patients who received the glucocorticoids therapy before surgery, only 1 patient of them got the GLM recurrence. For the 8 patients who received the postoperative glucocorticoids treatment, only 1 patient got the recurrence. For the 6 patients who received simple partial excision, the recurrence of the GLM may be up to 3. There was no statistical difference between the two groups who both received the 05). But compared with the pure surgery treatment, the difference was obviously (P<0.05). Conclusions The clinical presentation and imaging performance of GLM are unspecific, so the diagnosis of the GLM is difficult. There is no consensus regarding the optimal treatment for GLM. The glucocorticoids therapy may be necessary preoperatively or postoperatively. For the patient with clear preoperative biopsy diagnosis, preoperative glucocorticoids adjuvant chemotherapy followed by the wide excision may be an effective method.

Objective To investigate the diagnostic value of seven tumour-associated autoantibodies,including p53,PGP9.5,SOX2,GAGE7,GBU4-5,MAGE A1 and CAGE autoantibodies,in the newly diagnosed patients with lung cancer.Methods A total of 108 patients with newly diagnosed lung cancer,120 with benign lung diseases,227 with other cancers and 96 healthy controls were enrolled in the study.Their serum levels of seven autoantibodies were detected by enzyme linked immunosorbent assay (ELISA).The ROC curve was drawn and used to analyze their diagnostic efficiency for lung cancer.The diagnostic value of the combination of seven autoantibodies in different groups was also compared.Results The serum levels of seven autoantibodies in lung cancer patients were significantly higher than those in the patients with benign lung diseases or other cancers and healthy controls (P ＜ 0.05).The sensitivity,specificity and AUCROc of the combination of seven autoantibodies in the preliminary diagnosis of lung cancer were 62.00％,89.80％ and 0.769,respectively,and its sensitivity and AUCROC were higher than those of single autoantibody.The positive rate of the combination of seven autoantibodies in lung cancer patients was significantly higher than those in healthy controls (x2 =50.885,P ＜ 0.01) and the patients with benign lung diseases (x2 =56.341,P ＜ 0.01) or other cancers (x2 =46.812,P ＜ 0.01).Conclusion The combination detection of seven autoantibodies,including p53,PGP9.5,SOX2,GAGE7,GBU4-5,MAGE A1 and CAGE,may serve as potential markers for the diagnosis of lung cancer.

BACKGROUND:Vertebroplasty and kyphoplasty for osteoporotic vertebral compression fractures can result in many complications, such as bone cement leakage and adjacent-level fractures.
OBJECTIVE:To verify the possibility of biodegradable mesh-like microporous polymer bal oon for the treatment of osteoporotic vertebral compression fractures.
METHODS:Biodegradable mesh-like microporous P(DLLA-CL) bal oons were fabricated by electrospinning technique. Coated bal oons with the same specification was fabricated by coating P(DLLA-CL) onto the same mould. Morphology of the bal oons was observed by scanning electron microscopy. The bal oon leakage was observed by eyes after the injection of water or cement. The initial strength and stiffness were measured by a universal testing machine. The proliferation of MC3T3-E1 cel s on the bal oons was determined by laser confocal microscope and cel counting kit-8 assays. The biodegradation of bal oons in simulated body fluid, porcine pancreatic lipase, and fresh human serum was studied by residual weighing and scanning electron microscopy observation. Burst pressure of bal oons was measured after the bal oon was placed into a hole in the vertebral bone. For the in vitro calcium release tests, the bal oons were fil ed with calcium cement, tied, placed into 6atm ultrapure water, and then the calcium concentration was regularly determined.
RESULTS AND CONCLUSION:Mesh-like microporous bal oons presented with good fiber morphology, thickness distribution, and the presence of pores;on the coated bal oon surface, there was absence of specific morphology and porosity. Compared with the coated bal oon, the mesh-like microporous bal oon showed better mechanical properties, liquid permeability and burst pressure, to prevent leakage of bone cement and promote osteoblast adhesion and proliferation. In addition, the degradation of the mesh-like microporous bal oons was more uniform and stable than the coated bal oons, which may increase the calcium concentration in the injured vertebrae and wil be beneficial to the new bone growth and fracture healing.
