Objective To analyze the clinical correlation between UU infection and tubal pregnancy in order to guide the correct clinical treatment. Methods Cultivation was used to detect UU in villi tissue of 30 tubal preg-nancy patients and natural aborted pregnant women respectively. Results There was remarkable difference(P0.05) between the positive rate of UU in tubal pregnancy(80 % ) and natural pregnancy(16.7 % ). Conclusion UU may be one of major pathogenic microorganisms in tubal pregnancy, and it's necessary to detect and treat UU con-ventionally.

Objective To analyze optimal amount of drinking water,ways of drinking water,timelimit of drinking water on the effect of bowel preparation for intravenous pyelography (IVP) examination after oral administration of 50% magnesium sulfate 60 ml. Methods 200 patients who gave their consentfrom June 2009 to February 2010 drank 50% magnesium sulfate 60 ml for IVP check were divided into four groups. Group A: a large amount of graded oral administration of warm water 1200 ml within 1h; Group B: a small amount of oral administration of warm water 1200 ml within 1h;Group C: a large amount of graded oral administration of warm water 2000 ml within 1h; Group D: a medium amount of graded oral administration of warm water 1200 ml within 2 h. And then the bowel preparation effect of the four gro ups were analyzed. Results Through the comparison, group A was much better than the other groups on the aspects of cathartic satisfaction, the effective degree of reading films and flatulence. Conclusions To take a large amount of graded oral administration of warm water 1200 ml within 1h can improve cathartic satisfaction,the effective degree of reading films and flatulence.

Objective Treatment of type 1 diabetes mellitus has always posed a challenge to balance hyperglycemia control with hypoglycemia episodes. This review attempts to outline the application and research progress of real?time continuous glucose monitoring technology.Given the evolution of RT?CGM technologies,it is likely that today’ s more accurate RT?CGM systems will result in improved patient trust and reduced alert fa?tigue,translating into more sustained RT?CGM use,greater use of the RT?CGM data,and better outcomes.

AIM:To screen the miRNA related to blood stasis syndrome and to explore the genetic mechanism of blood stasis syndrome in hypertension.METHODS:Human umbilical vein endothelial cell line CRL-1730 was co-cul-tured with the human sera from healthy normal controls and hypertension patients to establish a blood stasis-hypertension cell modela.The hypertension patients showed qi deficiency and blood stasis, qi stagnation and blood stasis, cold retaining and blood stasis, heat retaining and blood stasis and non-blood stasis syndromes.The endothelial cell models of blood stasis in hypertension were established.Target cells were collected for total RNA extraction.The techniques of Solexa ( high-throughput sequencing method) and digital gene expression profiling were applied for screening the target miRNA, and miRWalk software was used for online prediction the mRNA which might be the relevant target.qRT-PCR was conducted to confirm the prediction.RESULTS:SAT1-Hsa-miR-199a-5p and ATF4-Hsa-miR-1283 were found to be highly expressed in these cell models.The expression of miR-1283 and miR-199a-5p was confirmed by qRT-PCR.CONCLUSION:miR-199a-5p and miR-1283 may be the relevant miRNA for the prediction of blood stasis syndrome in hypertension.

Objective To investigate the clinical efficacy and safety of high-frequency electric snare for the treatment of main airway neoplasm through bronchoscopy. Methods The clinical datas of 18 patients from July 2013 to April 2016, who had main airway neoplasm and were treated with high-frequency electric snare through bronchoscopy, were retrospectively analyzed. Meanwhile, the interventional bronchoscopic techniques partly included argon plasma coagulation and cryoablation. After operarion, the relief of symptoms and complications were observed. Results After operarion, the clinical symptoms, shortness of breath, dyspnea index score and the degree of airway stenosis were improved significantly. No serious complications such as massive hemoptysis occurred in all patients. Conclusion High-frequency electric snare is an effective and safe approach for the treatment of main airway neoplasm.

Jasmonic acid (JA), a plant endogenously synthesized lipid hormone, plays an important role in response to stress. This manuscript summarized the biosynthesis and metabolism of JA and its related regulatory mechanisms, as well as the signal transduction of JA. The mechanism and regulatory network of JA in plant response to biotic and abiotic stresses were systematically reviewed, with the latest advances highlighted. In addition, this review summarized the signal crosstalk between JA and other hormones in regulating plant resistance to various stresses. Finally, the problems to be solved in the study of plant stress resistance mediated by JA were discussed, and the application of new molecular biological technologies in regulating JA signaling to enhance crop resistance was prospected, with the aim to facilitate future research and application of plant stress resistance.
