Objective:To investigate the correlation between IL-10 and I1-17 expression levels in Mycoplasma pneumoniae pneumonia (MPP) and lung function.Methods:70 patients were included in this study.According to wheezing or not,they were divided into wheezing group and non-wheezing group.Another 30 healthy children were taken as a control group.After taking fasting blood 5ml,the serum IL-10 and IL-17 expression levels were detected by ELISA.The forced expiratory volume in one second (PEV1),peak expiratory flow (PEF) and forced vital capacity (FEV1 / FVC) of all subjects were detected.Results:The IL-10 expression level of the wheezing group were significantly different with that of the control group (P＜0.05) and that of the non-wheezing group (P＜0.05).The 1L-17 expression level of the wheezing group also had significant difference (P＜0.05) with that of the control group and non-wheezing group (P＜0.05).The IL-10 expression levels of wheezing and non-wheezing group all were lower than that of the control group.Whereas the IL-17 expression levels of wheezing and non-wheezing group all were higher than that in the control group.In addition,patients in wheezing group had higher PEV1,PEF,PVE1/FVC values than those in non-wheezing group,with significant difference (P＜0.05).The serum level of IL-10 expression of Mycoplasma pneumonia patients was positively correlated with PEV1,PEF and PVE1/FVC,while the serum level of IL-17 expression of Mycoplasma pneumonia patients was negatively correlated with PEV1,PEF and PVE1/FVC.Conclusion:The serum levels of IL-17 and IL-10 expression of Mycoplasma pneumonia children had close correlation with their pulmonary function.

Objective To study the apoptotic induction of Aspisol on melanoma A375 cells.Methods The growth inhibition effect of Aspisol on A375 cells was evaluated by MTY assay.Morphological assay was observed by inverted microscope.Early apoptofic rate in A375 cells Was anyzed by flow cytometry.Results The results of MTT assay demonstrated that the growth of A375 cells was inhibited by Aspisol in a time-and concentration-dependence (P＜0.01).FCM analysis showed that Aspisol could markedly induce apeptosis;the early apoptotie rate of A375 cells exposed to different concentrations of Aspisol for 24 h were significant differences(P＜0.05)compared with control group.Conclusion Aspisol could inhibit proliferation and induce apoptosis of A375 cells.

Objective To investigate the clinical effects and postoperative complications of arthrotomy and arthroscopy in repair of 170 menisci in 168 cases.Methods One hundred and sixty-eight patients with meniscus injury were repaired by arthrotomy or arthroscopy.They were 121 males and 47 females.There were 77 left knees and 91 right knees;117 medial menisci and 53 lateral ones.Their average age was 25.5?8.4 years old.Arthro- scopic repair methods included puncture and grinding,bio-absorbable meniscus arrow fixation,Outside-In suturing, Inside-Out suturing,Elite scuff instrument repairing,T-Fix fixation and FasT-Fix fixation techniques.The clinical results were assessed on the basis of symptoms,physical signs,Tegner scores and Lysholm scores of the cases. Postoperative complications were also investigated.Re-arthroscopic exploration was done for patients with obvious symptoms and physical signs.Results The average folluw-up time was 49.3?28.8 months.Their mean pre- operative Tegner score was 3.3?2.3,and their postoperative one 6.8?2.1 (P＜0.05).Their preoperative Lysholm score was 30.1?18.2,and their postoperative one 87.5?22.5 (P＜0.01).There were significant differences in Tegner and Lysholm scores before operation and after operation.Ninety-eight repaired menisci were rated as excellent(57.7%),57 as good (33.5%),10 as fair (5.9%),and five as poor (2.9%).The total ex- cellent and good result was 91.2%.Of the 19 patients with obvious symptoms and physical signs,re-arthroscopic exploration found no healing in five and partial healing in six.Postoperative complications included pain at the Outside-In suture nodes in three cases,referred pain at posterior articular capsule resulted from failed Outside-In meniscus anterior horn suturing in one case,and twinge at the meniscus arrow site in the posterior capsule in five cases.No serious lesion occurred at blood vessels or nerves.The postoperative complication incidence was 5.3%. Conclusion The eight methods of arthrotomy and arthroscopy to repair injured menisci investigated in our study can have a high successful rate and low perioperative and postoperative risk.

Objective To explore the effect of psychological nursing intervention on the pain, sleep quality and life quality of patients with gastric cancer. Methods A total of 84 cases of gastric cancer patients from January 2013 to January 2014 were randomly divided into intervention group and control group, 42 cases in each group, the control group was received conventional care, while the intervention group focused on the implementation of psychologicalnurs-ing intervention, SAS, SDS scores, VAS scores and PSQI scores before and after the intervention, and the general health, physiological function, physiological function, body pain, vitality, social function, emotional function, mental health quality of life scores were compared before and after intervention between two groups. Results After intervention, the SAS scores, SDS scores, VAS scores decreased significantly than before intervention and intervention group were lower than control group(P<0.05),the PSQI scores were significantly lower than before the intervention and intervention group were lower than the control group (P<0.05), after the intervention,the physical function, physical function, bodily pain, vitality, social functioning, role emotional, mental health scores were significantly higher than before intervention and intervention group were higher than the control group(P<0.05). Conclusion Positive psychological nursing interven-tion for gastric cancer helps to alleviate patients anxiety, depression and other negative psychological, reduce pain and improve sleep quality in patients, to further improve the quality of life of patients.

Objective To summarize the brain protection application experiences of combined internal and external blood shunt technologies for the in-situ three-fenestration revascularization of aortic arch.Methods From Feb 2017 to Jun 2018,8 patients with aortic arch leisons were treated by the in-situ three-fenestration techniques,including 3 aortic dissection,2 aortic aneurysm,3 postoperative TEVAR patients.We adopt the method of internal and external blood shunt technologies for brain protection using the vascular sheath for fenestration combined with carotid shunt tube skills,and using TCD to monitor the blood flow of brain.Results All operations completed successfully,and TCD showed no significant cerebral ischemia when aortic stent was used to cover the three branches of the aorta.The mean time of brain protection was (17.62 ± 6.87) minutes.One patient developed transient cerebral ischemia after surgery,and another one developed cerebral infarction.Conclusions The brain protection strategy of internal bypass combined with external converter technology maintain the brain blood flow,while is simple and feasible,it cannot completely avoid neurological complications.

Established in 2017, the Screening Cohort for Asian Nomadic descendants in China (Scan-China) has benefited over 180,000 members of a multi-ethnic population, particularly individuals of Mongolian descent compared with the general population (Han ethnicity), in the Inner Mongolia Autonomous Region, China. This cohort study aims to evaluate the effectiveness of cancer screening and serve as a real-world data platform for cancer studies. The 6 most prevalent cancers in China are considered—namely, breast, lung, colorectal, gastric, liver and esophageal cancer. After baseline cancer risk assessments and screening tests, both active and passive follow-up (based on the healthcare insurance database, cancer registry, the front page of hospital medical records, and death certificates) will be conducted to trace participants’ onset and progression of cancers and other prevalent chronic diseases. Scan-China has preliminarily found a disproportionately lower screening participation rate and higher incidence/mortality rates of esophageal and breast cancer among the Mongolian population than among their Han counterparts. Further research will explore the cancer burden, natural history, treatment patterns, and risk factors of the target cancers.

Objective:To investigate the efficacy of shunt after transjugular intrahepatic portosystemic shunt (TIPS) in liver cirrhosis accompanied with portal vein thrombosis (PVT).Methods:Forty-four cases with liver cirrhosis accompanied with PVT who underwent TIPS treatment from January 2015 to May 2018 were retrospectively analyzed. Clinical baseline data of the patients were collected. Portal vein pressure gradient (PVPG) before and after the surgery was recorded. Shunt patency was observed at 3, 6, 12, 18 and 24 months after the surgery. The influencing factors were determined by univariate and multivariate analysis.Results:Transjugular intrahepatic portosystemic shunt was successfully established in all 44 cases. The postoperative PVPG was lower than preoperative ( P < 0.01). The shunt patency rate after TIPS in PVT was 18.2% ( n = 8). The cumulative shunt patency rates at 3, 6, 12, 18, and 24 months after surgery were 95.5%, 90.7%, 90.7%, 86.8% and 74.4%, respectively. Univariate analysis showed that diabetes history, platelet level and prothrombin time-international normalized ratio were associated with postoperative shunt dysfunction. Multivariate analysis showed that diabetes history ( P = 0.007, OR = 28.606) was an independent risk factor for postoperative shunt dysfunction. Conclusion:TIPS is a safe and feasible procedure, which can effectively reduce the portal pressure in liver cirrhosis accompanied with PVT. Diabetic patients have a higher risk of postoperative shunt dysfunction. Therefore, clinical intervention should be strengthened for high-risk patients.

Adjusting time-dependent covariates into prediction models may help improve model performance and expand clinical applications. The methodology of handling time-dependent covariates is limited in traditional regression strategies (i.e., landmark model, joint model). For example, the number of predictors and practical situations which can be handled are restricted when using regression models. One new strategy is to use machine learning (i.e., neural networks). This review summarizes the methodology of handling time-dependent covariates in prediction models, such as applicable scenarios, strengths, and limitations, to offer methodological enlightenment for processing time-dependent covariates.

BACKGROUND:Previous studies have reported inconsistent results with positive,negative,and J-shaped associations between alcohol consumption and the hazard of aortic aneurysm and dissection(AAD).This study aimed to examine the connections between weekly alcohol consumption and the subsequent risk of AAD. METHODS:The UK Biobank study is a population-based cohort study.Weekly alcohol consumption was assessed using self-reported questionnaires and the congenital risk of alcohol consumption was also evaluated using genetic risk score(GRS).Cox proportional hazards models were used to estimate hazard ratios(HRs)with 95%confidence intervals(CIs)for the associations between alcohol consumption and AAD.Several sensitivity analyses were performed to assess the robustness of the results. RESULTS:Among the 388,955 participants(mean age:57.1 years,47.4%male),2,895 incident AAD cases were documented during a median follow-up of 12.5 years.Compared with never-drinkers,moderate drinkers(adjusted HR:0.797,95%CI:0.646-0.984,P<0.05)and moderate-heavy drinkers(adjusted HR:0.794,95%CI:0.635-0.992,P<0.05)were significantly associated with a decreased risk of incident AAD.Interaction-based subgroup analysis revealed that the protective effect of moderate drinking was reflected mainly in participants younger than 65 years and women. CONCLUSION:Our findings support a protective effect of moderate alcohol consumption on AAD,but are limited to participants younger than 65 years and women.
