Objective:This paper aims to bioinformatically analyze the target genes of miR-29b and to provide clues for cancer research targeting miR-29b. Methods:The differential expression levels of miRNAs in CD133+and CD133-A549 cells were detected using the miRNA PCR chip. Real-time polymerase chain reaction was performed to verify the partially differential expression of miR-NAs. Target genes of miR-29b were predicted by miRecords and analyzed by gene ontology and signal transduction pathway enrich-ment analysis. Results: The miR-29b expression was significantly decreased in the CD133+A549 cells compared with that in the CD133-cells. The number of miR-29b target genes was 106. The functions of these target genes were enriched in binding and extracel-lular matrix structural constituent (P<0.01). The JAK-STAT and TGF-βsignal transduction pathways were significantly enriched (P<0.05). Conclusion:The abnormal expression of miR-29b may be related to metastasis. Some of the predicted target genes of miR-29b were significantly enriched in the signaling pathways in relation to the tumors.

Purpose To explore the effects of progesterone receptor isoforms A and B ( PR-A,PR-B) on carcinogenesis and progres-sion of ovarian serous cystadenocarcinoma ( OSC) . Methods The expressions of PR-A and PR-B in 52 cases of OSC, 22 cases of o-varian borderline serous cystadenoma ( OBSC) , 22 cases of umbrella of normal fallopian ( UNF) were detected by immunohistochmical Elivision technique. Results The expression of PR-A in OSCs, OBSCs and UNFs were 94. 5%, 94. 5%, and 68. 38%, respective-ly, with there were statistical significance among three groups (P<0. 05). The expression of PR-B in OSCs, OBSCs and UNFs were 100%, 77. 27%, and 40. 38%, respectively, with there were statistical significance among three groups (P<0. 05). The difference of PR-A/PR-B ratio in OSCs, OBSCs and UNFs was statistical significance ( P<0. 05 ) . The expressions of PR-A and PR-B in OSCs were lower, there were statistical significance between the clinical stageⅠ+Ⅱ andⅢ+Ⅳ (P<0. 05), and histological gradeⅠandⅡ. The difference of PR-A/PR-B ratio between the histological gradeⅠandⅡin OSC was statistical significance. There was statistical significance of PR-B between OSCs with lymph metastasis and without lymph metastasis (P<0. 05). Expression of PR-A and PR-B in OSC was positive correlation (P<0. 05). Conclusion With the carcinogenesis and progression of OSC, the expressions of PR-A and PR-B gradually declined, and the downregulation of PR-B is more obvious, may be an important biological sign of malignant transfor-mation in ovarian tissue. The increasing ratio of PR-A to PR-B in OSC may indicate poor differentiation. The relatively higher expres-sion of PR-B may inhibit the lymph metastasis in OSC.

Objective To evaluate the efficacy and safety of dorsal root entry zone (DREZ) incision for pain induced by brachial plexus injury. Methods A cohort study was performed in 41 consecutive patients with pain induced by brachial plexus injury treated with DREZ incision from July 2005 to December 2007. Of all, 19 patients were amputated and had phantom limb sensation. Oral pain relief (0%-100%) and complications were followed up by one professional doctor. Oral pain relief rate ≥50% was considered satisfactory outcome. Results The proportion of patients with satisfactory pain relief was 90% (37/41), 81% (30/37), 77% (24/31) and 70% (16/23) at 2 weeks, 3 months, 6 months and last follow-up (over one year) after surgery. At last follow-up, 15 out of 16 patients with over 10 years of pain duration got satisfactory pain relief; while only 16 out of 25 patients with less than 10 years of pain duration got satisfactory pain relief (x2 =4.682, P =0.030). In 16 amputees who were followed up for more than three months, seven patients with alteration of phantom limb sensation got satisfactory pain relief, while only four out of nine patients without alteration of phantom limb sensation got satisfactory pain relief. Among 37 patients followed up for more than three months, severe neurological defects were found in three patients including one with mild motor disturbance in the ipsilateral lower limb and two with severe sensory disturbance in the ipsilateral lower limb. Conclusions DREZ incisions are effective and safe neurosurgical procedure for relieving pain induced by brachial plexus injury. The possible predictive factors of better outcome are the long preoperative pain duration and postoperative phantom limb sensation among amputees.

Objective To investigate the prevalence of year-round respiratory viral infection in children with lower respiratory tract infection (LRTI), and the relationship between respiratory viral infection and allergen sensitization in exacerbating asthma. Methods A total of 231 hospitalized children with acute LRTI were investigated from May 2013 to April 2014. The 5 most common respiratory viruses were isolated from nasopharyngeal aspirate using multiplex reverse transcription-polymerase chain reaction, including respiratory syncytial virus (RSV), adenovirus (AV), parainfluenza virus (PIV), influenza virus (IFV) and rhinovirus (RV). Atopic sensitization was defined if more than 1 serum specific immunoglobulin E level measured using immunofluorescence experiment was over 0.35 IU/mL. Results RSV was the most common pathogen of bronchiolitis in hospitalized children through the year. RV or IFV infections were more prevalent in asthma exacerbations compared to other LRTIs. AV was more likely to cause pneumonia. RV and IFV were associated with asthma exacerbations in children with atopic sensitization, but not in nonatopic children. Conclusion RV and IFV are associated with hospitalization for asthma exacerbation in children with atopic sensitization.

Objective To identify the risk factors for severe acute lower respiratory infections (ALRI) in children and to provide scientific basis for prevention and treatment of ALRI. Methods Several databases including Pubmed, Databases-Medline (Ovid), Embase, CINAHL and Global Health Library, CNKI, VIP and Wanfang Date were searched (1990.1-2014.12) for references. All selected studies were about risk factors of ALRI in children. The screening and quality evalua? tion of the literature data was conducted independently by two reviewers according to the inclusion and exclusion criteria. Stata 11.0 software was used for Meta-analysis. Results Meta-analysis of 27 included literature showed that seven risk fac?tors were significantly associated with severe ALRI:low birth weight, lack of exclusive breastfeeding, crowded household, ex?posure to indoor air pollution, malnutrition, living in a house with smokers or smoking in pregnant and HIV-exposed unin?fected condition. Conclusion The above seven risk factors play the important role in the development of ALRI in children. Furthermore, it emphasizes the need for further studies investigating other potential risk factors to decrease the possibility of childhood ALRI.
