Objective:To explore the necessity of monitoring polysomnography (PSG ) in snoring children.Method:The PSG were monitored in 162 children with snoring or apnea.Acording to results of PSG,162 cases were separated into two groups:group obstructive sleep apnea hypopnea syndrome(OSAHS) and group primary snoring(PS),monitoring data including:apnea hypopnea index(AHI),snoring index(SI),lowest oxygen saturation(LSaO_2) and time of SaO_2<0.9,all data were undertaked statistical analysis. Result:In all 162 snoring cases,150 cases(92.6%) belong to group OSAHS,12 cases(7.4%) belong to group PS;Differences of data of age,sex and body mass index(BMI) are not significant but that of AHI,SI,LSaO_2 and time of SaO_2<0.9 are significant(P<0.05).Conclusion:It's necessary to monitor PSG in snoring children for early diagnosis and correct treatment to avoid disadvantage of OSAHS.

Colorectal carcinogenesis is the result of accumulation of genetic and epigenetic alters.Gene mutations and changes in DNA methylation patterns,resulted from genomic instability,are the main molecular events in colorectal cancer.Identification of key mutations and methylation phenotypes in genes leading to colorectal cancer progression,and molecular pathology classification and diagnosis are likely to be the prerequisites for individualized and targeted treatment.

Objective To explore the effect of different speed of bladder irrigation after transurethral resection of prostate.Methods 477 cases of benign prostatic hyperplasia,who received transurethral resection surgery were collected.According to the date of surgery,they were divided into observation group(in a single day,249 cases)and control group(double day,228 cases).The normal saline was used in the two groups,and the control group was washed with the conventional bladder irrigation,and the observation group was treated with the early rapid(no speed limit opening)and the routine velocity alternating flushing.The incidence of bladder spasm,the incidence of bladder spasm,the bleeding of bladder and the changes of heart rate and the mean arterial pressure of 24h were compared. Results Urine turned clear time,the total fluid,postoperative 5d red blood cell count of the observation group[(19.8 ± 8.3)h,(44.7 ±6.1)L,(25.8 ±11.3)months/μL]were significantly lower than the control group[(25.4 ±9.0)h, (52.3 ±7.4)L,(33.4 ±10.1)months/μL],the differences between the two groups were statistically significant(t =-6.270,-2.417,-10.459,all P <0.05).The incidence rate of bladder spasm,seizure frequency and duration per capita of the observation group[24.5%,(2.2 ±0.6)times,(15.4 ±4.6)min]were significantly lower than the control group[46.9%,(6.7 ±1.2)times,(27.6 ±5.1)min],the differences between the two groups were statistically significant(χ2 =8.725,t =-13.250,t =-18.066,all P <0.05).The postoperative rinse 1h,2h and 24h heart rate,mean arterial blood pressure had no statistically significant differences(all P >0.05).Conclusion The early rapid and conventional alternating washing method can improve the seizure of bladder spasm after prostatectomy,and reduce the bleeding of bladder.

Objective To investigate the pathogenesis of interleukin-21 (IL-21)role in primary biliary cirrhosis (PBC).Meth-ods 38 cases of PBC were selected for the study.35 caeses of healthy subjects were selected as the control group in January 2012 to January 2014 from Shenzhen Fuyong People’s Hospital of Baoan District and the Third People’s Hospital of Shenz-hen.The levels of IL-21,IL-17 of two groups were measured with Enzyme-linked immunosorbent assay (ELISA).The levels of T helper lymphocytes 17 (Th17),regulatory T cells (Treg)cells ratios of two groups were measured with flow cytome-try.The relationship of IL-2 1 and liver function were analyzed with pearson correlation.Another analysis of pyruvate through the establishment of in vitro deaminase complex E2 subunit (PDC-E2)peptides relationship with Th17 and Treg cell.Results The levles of IL-17 (18.23±4.12)ng/L,IL-21 (512.25±18.25)ng/L,Th17 (3.98±0.98)%,Th17/Treg (39.25±3.25)% of PBC group were significantly higher than the control group (7.89±3.26)ng/L,(212.98±21.52)ng/L,(0.92±0.21)% and (12.98±3.12)%,while the PBC group Treg (3.11±0.85)% were lower than the control group (8.36±1.12)%.IL-21 were positive correlation with IL-17,Th17 (t=8.886,7.021,4.448,10.112,5.125,P<0.05).In vitro experiments showed that the addition of IL-21 in the culture system,the levels of Th17 (2.41±0.82)%,Th17/Treg cells(32.98±3.12)% were significantly higher than the control group(0.98±0.21)%,(12.25±3.25)%,while Treg (4.75 ±0.68)% were lower than the control group(11.85±0.96)%,the difference was statistically significant (8.521,6.489, 8.236,P<0.05).Conclusion IL-21 levels increased with the pathogenesis of PBC has a close relationship,which can pro-mote the reaction of PDC-E2 Th1 7/Treg immune imbalance caused thereby occurs mediated by PBC.

Circulating tumor cells (CTCs) in breast cancer patients can be detected by Cell Search system. Results from recent studies suggested that CTCs level might serve as a prognostic marker and be used in the early assessment of therapeutic response in patients with metastatic breast cancer. However the role of CTCs in early stage breast cancer is not well established. Large prospective trials are needed to further understand its biological characteristics and to confirm its role as a predictive and prognostic marker.

ObjectiveTo seek the approach to the initial diagnosis of pulmonary embolism through analysis and conclusion of the clinical features of pulmonary embolism.MethodsThe high risk factors,clinical manifestation and results of common auxiliary examinations of 23 patients with pulmonary embolism were analyzed retrospectively.ResultsThere were 91.30％(21/23)patients with high risk factors.The common symptoms were dyspnea (91.30％,21/23) and chest tightness (69.57％,16/23 ),while the triad of pulmonary embolism merely accounted for 13.04％ (3/23).And other symptoms included palpitation,chest pain,hemoptysis and syncope,etc.Blood gas analysis indicated that there were hypoxemia and hypocarbia.The positive rate of D-dimer was 91.30％ (21/23).The abnormal rate of electrocardiogram was 91.30％( 21/23 ) and the abnormal rate of echocardiography was 86.96％(20/23).ConclusionAppropriate approach to the initial prognosis can help to establish the diagnosis of patients with suspected pulmonary embolism as early as possible,as well as differentiate other cardiopulmonary diseases.

Uncoupling protein 2 (UCP2), a member of the mitochondrial inner membrane carrier family, partly dissipate the proton electrochemical gradient, decrease ATP production. UCP2 limits production of reactive oxygen species (ROS) and inhibits insulin secretion and regulates fatty acid oxidation. FFA, PPAR?,leptin, thyroid hormones and so on could regulate the UCP2 expression. The function of UCP2 in myocardial energy metabolism remains unknown.

Radiotherapy has been proven to enhance tumor-specific immune response and provide targets for immune drugs. Immune checkpoint inhibitors represented by PD-1/PD-L1 combined with radiotherapy can enhance anti-tumor activity and exert abscopal effect. In this article, research progress on the basic study and clinical trials and challenges of radiotherapy combined with PD-1/PD-L1 inhibitors in the treatment of breast cancer were reviewed.
