Objective To explore the role of combined respiratory function combined with drug therapy in the rapid recovery of lung cancer patients, and to provide reference for clinical treatment. Methods Forty patients with early non-small cell lung cancer (NSCLC) who underwent surgical treatment from January 2012 to December 2015 were selected as subjects and were randomly divided into intervention group and control group (n=20) according to the order of admission. All patients were treated with routine chemotherapy on the basis of routine chemotherapy of lung cancer, and routine perioperative care was carried out. The intervention group received comprehensive respiratory function exercise on the basis of them. There were psychological nursing, health education, perioperative respiratory function exercise and so on. The incidence of postoperative pulmonary complications, quality of life improvement and postoperative rehabilitation were compared between the two groups. Results The incidence of pulmonary complications in the intervention group was 5％ (1/20, only one case of pneumonia), the incidence of pulmonary complications in the control group was 35％ (7/20, 4 cases of pneumonia, two cases of atelectasis, one case of hypoxemia),the incidence of postoperative pulmonary complications in the intervention group was significantly lower than that in the control group (P<0.05). The scores of SF-36 in the intervention group were higher than those in the control group, the difference was statistically significant (P<0.05). The extubation time and postoperative hospital stay in the intervention group were shorter than in the control group. The 6-minute walking test (6MWK) was longer than the control group, the difference was statistically significant (P<0.05).Conclusion Comprehensive respiratory function combined with treatment with etestin hydrochloride can reduce the early postoperative pulmonary complications in patients with early non-small cell lung cancer, improve its quality of life and promote rapid postoperative rehabilitation.

HIC1 (hypermethylated in cancer 1) encodes a transcriptional repressor,and extensively resides in various kinds of normal tissue.HIC1 gene is located in chromosome 17p13.3,in which loss of heterozygote or super-methylation is frequently found in a variety of human cancers.As a new tumor marker,HIC1 has been confirmed down-regulated in a wide variety of solid cancers because of HIC1 promoter hypermethylation,and may be associated with tumor prognosis.As a tumor suppressor,HIC1 participates in the development of tumor process through various ways,and is involved in cell proliferation,tumour growth,and angiogenesis.Therefore,the abnormal hypermethylation or the loss of expression of HIC1 in tumor cells or abnormal function could be one of the important mechanisms of tumor development,and may become a new potential therapeutic targets for cancer.

Objective To study the incidence of hypertension in patients with different severity of obstructive sleep apnea hypopnea syndrome(OSAHS) and to observe the effects of short-term continuous positive airway pressure (CPAP) treatment on hypertension in patients with hypertension Ⅲ complicated with OSAHS.Methods According to sleep apnea hypopnea index (AHI) and the lowest oxygen saturation value at night,184 patients with OSAHS were divided into mild group(n =55),moderate group(n =63) and severe group(n =66).We observed the incidence of hypertension among patients and their mean systolic and diastolic blood pressures before sleep and after wakening.There were 46 patients with severe OSAHS combined with hypertension Ⅲ received short-term (at least 7 days) CPAP treatment.We observed and analyzed the effect of CPAP on blood pressure values.Results In the 184 cases,incidence of hypertension of the three groups were 36.4％ (20/55),42.9％ (27/63) and 62.1％ (41/66) respectively.The incidence of hypertension in OSAHS patients was significantly higher in the severe group than in the moderate group (x2 =4.799,P ＜ 0.05) and the mild group(x2 =7.962,P ＜ 0.05).There were significant differences among mild,moderate and severe OSAHS patients in mean systolic and diastolic blood pressures before sleep Systolic ((135.08 ± 6.71) mm Hg vs.(136.59 ± 15.14) mm Hg vs.(144.73 ± 15.80)mm Hg,F =4.202,P ＜0.05) and Diastolic((90.96 ±6.06)mm Hg vs.(91.41 ± 4.05) mm Hg vs.(94.13 ± 13.97) mm Hg,F =13.690,P ＜ 0.05)) and after wakening Systolic((136.83 ± 8.23) mm Hg vs.(137.89 ± 17.03)mm Hg vs.(148.59 ± 14.83) mm Hg,F =4.158,P ＜0.05) and Diastolic((91.25 ± 9.96) mm Hg vs.(93.40 ± 8.82) mm Hg vs.(98.75 ± 9.39) mm Hg,F =5.638,P ＜0.05)).Severe OSAHS patients had significantly higher systolic and diastolic blood pressures after wakening than before sleeping (P ＜ 0.05).The changes of blood pressure had significant difference after CPAP treatment than before CPAP treatment (Systolic:(175.09 ± 9.66) mm Hg vs.(168.22 ± 8.55)mm Hg,t =3.556,P＜0.05;Diastolic:(105.82 ± 12.44) mm Hg vs.(100.61 ± 11.26) mm Hg,t =2.741,P ＜0.05).Conclusion OSAHS and hypertension are closely related to each other.CPAP is an effective treatment to OSAHS combined with hypertension.

Objective: To evaluate the polysomnology results along with mandibular titrated advancement using oral appliance to treat obstructive sleep apnea and hyponea syndrome(OSAHS).Methods: Several electronic databases (PubMed, Embase, Cochrane Library, CNKI, VIP, and Wanfang) were systematically searched up to September 2015.There was no restriction of language or source of information.All randomized clinical trials (RCT) and before-after trials (BAT) comparing at least two different mandibular advancements were included.Two independent reviewers selected the studies, extracted data and evaluated risk of bias by quality assessment.Data were pooled using a fixed-effects model, and the summary effect measure was calculated by risk ratio (RR) and 95%CI.Meta-analysis was performed using RevMan 5.3 software.Results: Two RCTs and five BATs were included in the review.Among the five BATs, two of them were randomized, while the other three were not.Outcomes including apnea hypopnea index (AHI), oxygen desaturation index (ODI), success rate (reduction of AHI or ODI >50%), normalization rate (AHI or ODI<10/h) were assessed in this review.Based on the trial design and quality assessment, four studies were included for meta-analysis.No significant difference in the success rate was found between the group with 50% of the maximal mandibular advancement (MMA) and the group with 75% of MMA [I2=0%, RR=0.93, with 95%CI (0.80, 1.09)].No significant dif-ference in the normalization rate was found between the 50% of MMA and 75% of MMA groups [I2=45%, RR=0.85, with 95%CI (0.68, 1.06)].Subgroup analysis displayed that the severity of OSAHS before treatment was a potential factor affecting the normalization rate.Conclusion: Based on current available evidence, the success rate and normalization rate for treating OSAHS in the patients with 75% MMA were not found to be significantly higher than those with 50% MMA.Due to small simple size in this meta-analysis, the results of the present study should be interpreted with caution.Further prospective studies are needed to strengthen the evidence.

Objective To determine the median effective dose (ED50) of 0.375 ％ ropivacaine for ultrasound-guided subgluteus approach to the sciatic nerve block in the elderly patients.Methods Thirty ASA Ⅰ-Ⅲ patients of both sexes,aged 65-85 yr,scheduled for foot or ankle surgery under the sciatic nerve block,were enrolled in this study.The patients were placed in the Sim's position and received the sciatic nerve block using the posterior subgluteus approach guided by ultrasound.The initial dose of 0.375％ ropivacaine was 14.5 ml in the first patient and the ratio between the 2 successive doses was 1.2.The ED50 and 95 ％ confidence interval of ropivacaine were calculated by up-and-down technique.Results The ED50 and 95％ confidence interval of 0.375％ ropivacaine resulting in complete block of the sciatic nerve by using the ultrasound-guided subgluteus approach were 13.4 and 11.5-16.2 ml,respectively.Conclusion The ED50 of 0.375 ％ ropivacaine for ultrasound-guided subgluteus approach to the sciatic nerve block is 13.4 ml in the elderly patients.

Aim To quantitatively analyze the lymphocyte proliferation using the time-series data of carboxyfluorescein diacetate succinimidyl ester(CFSE).Methods The model of immune suppression in mice was created by cyclophosphamide and CFSE dye was used for staining the lymphocyte of both control group and treatment group animals. The data were analyzed through mathematical model-fitting.Results The first generation of cell proliferation of the control group and treatment group were 27.17 h and 22.88 h; cell death rates in each division were respectively 20% and 40%; the half-life of cells before the proliferation was respectively 31.53 h and 43.32 h.Conclusions The mathematical fitting of CFSE data can quantitatively analyze the mechanism of the drugs attecting the proliferation of lymphocyte.In this experiment the mechanism of cyclophosphamide inhibiting lymphocyte proliferation may be due to the increase of cell death rate of each division caused by cyclophosphamide.
