Objective To observe the effect of bilateral movement training on upper extremities dysfunction in stroke patients in convalescent phase. Methods 52 patients with hemiplegia were randomly divided into treatment group (n=26) and control group (n=26). The treatment group accepted bilateral upper extremities movement training, and the control group accepted routine neurodevelopment training mainly with affected upper extremities, for 6 weeks. They were assessed with Fugl-Meyer Assessment upper-extremity section (FMA-UE) and modified Barthel Index (MBI) before and after treatment. Results The FMA-UE and MBI scores improved in both groups after treatment (P<0.01), and improved more in the treatment group than in the control group (P<0.001). Conclusion Bilateral movement training may improve upper extremity function and activities of daily living more effectively for stroke patients in convalescent phase.

Objective:To analyze the characteristics of respiratory pathogen spectrum in adult patients with acute exacerbation of bronchiectasis and its correlation with the severity of disease.Methods:A total of 108 patients with stable bronchiectasis from January 2014 to May 2018 in the Third People′s Hospital of Haikou City were enrolled. Sputum bacteria were cultured and common respiratory viruses in sputum and nasal swabs were detected by fluorescence quantitative polymerase chain reaction(PCR). All bronchiectasis patients were followed up for 1 year. Sputum bacteria culture and PCR virus detection were performed again in patients with acute exacerbation, and the differences of respiratory pathogen spectrum in patients with different severity of acute exacerbation were compared.Results:During the follow-up period, there were 53 cases of acute exacerbation events and a total of 91 case-times (up to 5 times per patient). The positive rates of sputum virus and nasal swab virus in patients with acute exacerbation were significantly higher than those in patients with stable period [39.6% (36/91) vs. 15.1% (8/53) , 45.1% (41/91) vs. 9.4% (5/53) ], and there were significant differences ( χ2=8.460, 13.621, P<0.05). However, the total positive rate of sputum bacterial culture in acute exacerbation and stable period had no significant difference ( P>0.05). The positive rate of Pseudomonas aeruginosa [0, 34.6% (9/26) ,52.4% (22/42) ] and rhinovirus [8.7% (2/23) ,3.8% (1/26) ,23.8% (10/42) ] in sputum among mild patients (16 cases, 23 case-times), moderate patients (16 cases, 26 case-times) and severe patients (21 cases, 42 case-times) in acute exacerbation stage were significant differences ( P<0.05). The levels of C-reactive protein (CRP) and interleukin (IL)-8 in patients in mixed infection of bacteria and viruses group in acute exacerbation stage were significantly higher than those in negative group, bacteria group and viruses group [CRP: (45.6 ± 23.0) mg/L vs. (11.2 ± 2.7) , (32.3 ± 10.2) , (21.3 ± 8.0) mg/L; IL-8: (9.0 ± 2.5) ng/L vs. (1.5 ± 0.9) , (1.8 ± 1.1) , (2.0 ± 1.3) ng/L], and there were significant differences ( F=23.012, 9.926, P<0.05). The hospitalization rate of patients in mixed infection of bacteria and viruses group was significantly higher than that in negative group, bacteria group and viruses group [29.6% (8/27) vs. 0, 16.7% (4/24) , 1/18] , and there were significant differences ( χ2=7.691, P<0.05). Conclusions:The positive rate of respiratory viruses in acute exacerbation of bronchiectasis in adults is significantly higher than that in stable stage. Pseudomonas aeruginosa and rhinovirus are the main infections in moderate and severe patients, Haemophilus parainfluenzae and influenza A virus are the main infections in mild patients, and the patients with mixed infection of bacteria and viruses have severe systemic inflammatory reaction and high hospitalization rate.

OBJECTIVETo demonstrate that estrogen stimulates the angiogenesis of children' s hemangioma.

METHODSA piece of hemangioma biopsy was embedded in fibrin gel, and a model in vitro of angiogenesis of human hemangioma was then established. The angiogenesis of hemangioma in each group was interfered by the estrogen and tamoxifen. There were four groups divided into the followings: the group with estrogen, the group with tamoxifen, the group with estrogen + tamoxifen and the control. The dimension of newborn tubule area in the 3rd, 6th, 9th day after the culture was calculated to compare statistically differences among the groups.

RESULTSIn the model of angiogenesis of hemangioma, microvessels grew out from the tissue sample in 2 to 3 days after the culture, and in 8 to 9 days a complex network of microvessels had been shown, the tending to inactivity. On the 3rd,6th and 9th day after the culture the dimension of newborn tubule area of the group of estrogen [(2.84 +/- 0.20) mm2 (12.93 +/- 0.85) mm2 (22.47 +/- 1.40) mm2] were larger than those of the control [(1.98 +/- 0.17) mm2, (7.51 +/- 0.48) mm2, (11.26 +/- 0.73) mm2]. Those of the group of estrogen + tamoxifen [(1.08 +/- 0.11) mm2, (3.54 +/- 0.31) mm2, (5.72 +/- 0.40 mm2] and the group of tamoxifen [(1.13 +/- 0.14) mm2 (4.26 +/- 0.29) mm2, (6.08 +/- 0.42) mm2] were smaller than those of the groups of the estrogen and the control (P < 0.05).

CONCLUSIONSThe estrogen may stimulate the angiogenesis of children's hemangioma, and the tamoxifen may reverse the process.

Objective To investigate the effects of 3 different ventilation methods,including conventional mechanical ventilation(CMV),high-frequency oscillatory ventilation(HFOV) and partial liquid ventilation(PLV),on the morphology of type Ⅱ alveolar epithelium cell (ACE Ⅱ) of newborn piglet with acute lung injury (ALI).Methods Twenty-four less than 3-day-old newborn piglets were enrolled.After ALI was established with saline lavage (38 ℃,0.035 L/kg),newborn piglets were randomly assigned to 4 study groups:control group(n =6,no ventilation),CMV group(n =6),HFOV group(n =6),and PLV group(n =6,38 ℃,0.018 L/kg).Piglets in the 4 groups were sacrificed after being ventilated for 24 hours,and the number,area,density of fluorescence of ACE Ⅱ were detected.Results Through 24 hours mechanical ventilation,the numbers of ACE Ⅱ in CMV group,HFOV group and PLV group remained were 30 ± 5,52 ± 5,81 ± 7,respectively,while areas of fluorescence were 340.40 ± 47.50,329.69 ± 124.50,295.55 ± 109.30,respectively,and there were significant differences among the 3 groups,and the population mean of density of fluorescence had significant difference among the 3 groups.The number of ACE Ⅱ remains was lowest in CMV group compared with HFOV group(P =0.026) and PLV group (P =0.000),and the density of fluorescence of ACE Ⅱ was lowest in CMV group compared with HFOV group (P =0.001) and PLV group (P =0.002).Conclusions Different mechanical ventilations have various effects for ACE Ⅱ,and CMV is the most harmful mechanical ventilation on ACE Ⅱ,while PLV is the least harmful.

【Objective】 The two databases，GEO（gene expression omnibus，GEO）and TCGA（the cancer genome alas ，TCGA），were analyzed using bioinformatics methods to screen differentially expressed genes associated and their related regulatory networks in prostate carcinoma. 【Methods】 The prostate carcinoma gene expression chip data （GSE46602 ，GSE55945） downloaded from the GEO database were integrated into the RNA- seq data of the TCGA database. And the differentially expressed genes analysis was performed using GEO2R and the edgeR package of R software to extract common significant differentially expressed genes. The clusterProfiler package of R software was used to enrich the GO（gene ontology ，GO）function enrichment analysis and KEGG（kyoto encyclopedia of genes and genomes， KEGG）pathway analysis. Differentially expressed genes were further constructed into a protein-protein interaction（PPI） network to screen out key genes for regulatory protein expression in prostate carcinoma. Gene analysis results were combined with TCGA clinical follow-up data to analyze the clinical prognostic value of key node genes. 【Results】A total of 278 significant differentially expressed genes were extracted，of which 178 genes were down- regulated and 100 genes were up-regulated. These genes were closely associated with the function and pathway enrichment such as the regulation of proliferation of epithelial cells，metabolism of benzene- containing compounds，the glutathione metabolism，and focal adhesion. The protein-protein interaction network analysis revealed three key protein expression modules and 12 key node genes. Among these key genes，EDN3（endothelin-3），EDNRB（endothelin receptor B）and AMACR（alpha-methylacyl- coa racemase）were closely related to the survival rate of prostate cancer patients. 【Conclusion】Through bioinformatics analysis of gene chip and RNA-seq data in prostate carcinoma，we found that EDN3，EDNRB and AMACR may play an important role in the occurrence and development of prostate carcinoma.

Objective To discuss the application effect of using a stone extractor balloon catheter to assist in crossing the anastomotic stenosis in treatment of anastomotic biliary stenosis after liver transplantation using endoscopic retrograde cholangiopancreatography(ERCP).Methods Clinical data of 48 patients who developed anastomotic biliary stenosis after liver transplantation and underwent ERCP treatment were collected.Upon unsuccessful use of a dilation catheter to cross the stricture,attempts were made to cross the anastomotic biliary stenosis by using a stone extractor balloon catheter.The success rate of the procedure was recorded,intraoperative conditions were observed,treatment outcomes and complications were analyzed.Results The main presenting symptoms in the 48 patients on admission were abdominal discomfort(32 patients),fever(7 patients),pruritus(4 patients),jaundice(3 patients),and no obvious symptoms(2 patients).Preoperative magnetic resonance cholangiopancreatography(MRCP)examination revealed isolated stricture of the anastomotic site in 35 cases,and stricture associated with stones in 13 cases.Using the stone extractor balloon catheter as a guide,guidewire crossing of the anastomotic stenosis was successful in 26 cases,resulting in a success rate of 54.17%(26/48).Through statistical analysis of the successful group and the failed group,there was a significant difference in whether the distal biliary dilatation between the two groups,and the difference was statistically significant(χ2 = 8.39,P = 0.004).In the 26 successfully treated cases,alanine transaminase(ALT),aspartate transaminase(AST),γ-glutamyl transpeptidase(γ-GT),alkaline phosphatase(ALP),and total bilirubin(TBiL)levels decreased significantly 48 hours after the procedure(P<0.05),and no serious complications occurred.Conclusion The use of a stone extractor balloon catheter significantly increases the success rate of crossing anastomotic stenosis in the treatment of anastomotic biliary stenosis after liver transplantation,especially in cases with distal dilatation of the common bile duct.This approach is safe and worth promoting.
