ObjectiveTo evaluate the clinical efficacy of foot therapy in intervening sleep disorder and improving sleep quality in breast cancer during chemotherapy.MethodTotally 120 eligible patients were randomized into a treatment group and a control group, 60 in each group. The treatment group was intervened by Chinese medicinal steaming washing plus acupoint application, while the control group was by conventional treatment. The effects on sleep quality and sleep duration were observed and compared. ResultThe total effective rate was 68.3% in the control group versus 90.0% in the treatment group, and the difference was statistically significant (P<0.05). The sleep quality, sleep duration, sleep disturbance, and Pittsburgh Sleep Quality Index (PSQI) score in the treatment group were more significantly improved than those in the control group after treatment (P<0.05).Conclusion Foot therapy can obviously improve the sleep quality of breast cancer patients during chemotherapy, and reduce the occurrence rate of sleep disorder during chemotherapy.

Objective To investigate the efficacy of wax therapy plus functional training in treating ankylosing spondylitis. Method One hundred patients were randomly allocated to treatment and control groups, 50 cases each. The treatment group received wax therapy plus functional training and the control group, functional training alone. One course of treatment consisted of seven days in both groups. The therapeutic effects clinical were evaluated after two course of treatment. Result Joint pain severity and morning stiffness time improved in both groups after treatment (P＜0.05 or P＜0.01) and did more in the treatment group than in the control group (P＜0.01). The total efficacy rates in the two groups were 84.0%and 66.0%, respectively;there was a statistically significant difference between the two groups (P＜0.05). Conclusion Wax therapy plus functional training is safe, reliable, convenient and easy to perform in clinical treatment of ankylosing spondylitis.

Objective To discuss the clinical effect of normal saline flushing and heparinized saline flushing in invasive arterial blood pressure monitoring in the critical patients. Methods A total of 140 critical patients were randomly divided into the experimental group and the control group with 70 cases in each group according to the envelope method. The experimental group used normal saline for tube flushing, the control group used heparinized saline (5 U/ml) for tube flushing. The incidence of complications and coagulation index were compared between two groups. Results There was no statistically difference in the incidence of the catheter jam and local infection (P>0.05). The incidence of bleeding events was 14.3% (10/70) in the control group, which was higher than 2.9% (2/70) of the experimental group. The difference was statistically significant(χ2=4.466, P<0.05). The activated partial thromboplastin time, prothrombin time of the control group were (32.22 ± 4.22) s, (11.56 ± 2.12) s, which were longer than (29.84 ± 3.64) s, (10.66 ± 1.48) s of the experimental group. And international normalized ratio of the control group was 1.12±0.14, which was higher than 1.03±0.20 of the experimental group. The difference was statistically significant (t values were-3.573,-2.912,-3.084, P <0.05). Conclusions The normal saline flushing liquid was more safer and reliable in the invasive arterial blood pressure monitoring.

OBJECTIVE To evaluate risk factors of the death among lung cancer patients with nosocomial pneumonia.METHODS A total of 312 lung cancer patients with nosocomial pneumonia in our hospital were retrospectively analyzed.RESULTS Eighty-seven patients died and remaining 225 patients were cured finally.Risk factors by multivariate analysis were more than 62 years old(OR 1.75,95%CI 1.06-2.98),metastatic disease(OR 9.24,95%CI 5.21-16.17),bacteria/fungi infection(OR 2.31,95%CI 1.15-4.67),and lower serum albumin concentration(OR 1.87,95%CI 1.08-3.13).CONCLUSIONS Older,metastatic diseases,double infections and lower serum albumin concentration are the risk factors correlated with the mortality among lung cancer patients with nosocomial pneumonia.

AIM:To study lipopolysaccharide (LPS)-stimulated secretion of endothelin-1 (ET-1) and adrenomedullin (Adm) from human vascular endothelial cells (HVEC) and its mechanism. METHODS:In cultured HVEC, LPS was used to stimulate ET-1 and Adm secretion from HVEC. The contents of ET-1 and Adm in medium were determined by radioimmunoassay. RESULTS:LPS stimulated secretion of ET-1 and Adm from HVEC in time-dependent and concentration-dependent manner. The ratio of secreted ET-1 to Adm was not changed compared with the control group. The increase of ET-1 could be inhibited by inhibitor of extracellular signal-regulated protein kinases (PD098059) and inhibitor of P38 kinase (SB202190)（P＜0.01）, while the increase of Adm could only be inhibited by SB202190（P＜0.05）, both had no response to inhibitor of protein kinase C (H7), inhibitor of calmodulin (W7), inhibitor of calcineurin (cyclosporin A) and inhibitor of Ca2+ (nicardipine)（P＞0.05）.CONCLUSION:ERKs and P38 signal pathways may play an important role in the secretion of ET-1 from LPS -stimulated HVEC, while only P38 kinase signal pathway is invovled in the secretion of Adm.

Objective:To explore the role of lectin-like oxidized low density lipoprotein (ox-LDL) receptor(LOX1) in ox-LDL stimulating endothelial nitric oxide(NO) production. Methods: LOX1 mRNA expression was detected by reverse transcription-polymerase chain reaction(RT-PCR). The quantity of NO was detected by Enzyme-method. Results: Incubation of ox-LDL increased endothelial NO production and LOX1 mRNA expression. When HUVECs were incubated with ox-LDL as well as the inhibitor of LOX1, polyinosinic acid,the increase of NO production and LOX1mRNA expression were attenuated. Conclusion: Ox-LDL enhanced endothelial NO production in a concentration-dependent manner, and the effect of ox-LDL on endothelial NO was mediated by LOX1.

Objective To explore the role of σ1 receptor (σ1R) in the clinical prognosis of cervical cancer,and provide a theoretical basis for σ1R targeted molecular therapy through observing the inhibition of synthetic σ1R-specific ligand compounds on the growth of cervical cancer cells. Methods (1) Immunohistochemical or immunocytochemistry staining were respectively used to detect the expression and localization of σ1R protein.(2)The Cancer Genome Atlas (TCGA) data set was used to validate our results. (3)Two series of 4 novel σ1R ligand compounds were synthesized by altering the N-terminal substituents on the piperidine ring of the prezamicol analogue, named as 14a, 14e, 15c and 15f. Methyl thiazolyl-tetrazolium (MTT) assay was detect the anti-proliferative effect of the four compounds on HeLa and SiHa cells. Compound 14a with potent inhibitory activity and the highest specificity of σ1R was selected for further experiments. Scratch test was observed the migration effect of compound 14a on HeLa and SiHa cells. Flow cytometry was determined cell cycles and apoptosis. Results (1) Immunostaining of σ1R protein was located in the cytoplasm and nucleus of cervical epithelium. The expression of cervical squamous cell carcinoma (SCC) was significantly higher than those of high-grade squamous intraepithelial lesion (HSIL) or normal cervical tissues. There was no significant difference in the expression of σ1R between HSIL and normal cervical tissues. σ1R expression in cervical adenocarcinoma (AC) was higher than that in SCC (P=0.020). The nuclear expression rate of σ1R in AC (10/18) was higher than that of SCC (27.1%, 19/70; P=0.024). The median overall survival (MOS) of σ1R-positive SCC patients was lower than that of σ1R-negative patients [(45.8±3.1) vs (51.7±2.9) months, P=0.045]. MOS of the patients with σ1R nuclear positive SCC was lower than that of non-nuclear staining [(38.9±3.8) vs (48.7±2.1) months, P=0.022]. MOS of the patients with σ1R nuclear positive AC was lower than that of non-nuclear staining [(35.0± 6.3) vs (44.2±4.2) months, P=0.034]. (2) Analysis of TCGA data showed that σ1R expression of in SCC was correlated with age (P=0.005). σ1R expression in AC was significantly associated with advanced stage, lymphnode metastasis and vascular invasion (all P<0.05). MOS of AC patients with σ1R overexpression was significantly lower than that of the patients with low expression (P=0.034). There was no significant difference in the MOS of different expression of σ1R mRNA in SCC patients(P=0.930). (3) MTT assay showed that these four compounds could suppressed the growth of HeLa and SiHa cells in time- and dose-dependent manner. The growth inhibition rates of HeLa and SiHa cells at 48 hours treated by combination of different concentrations of nedaplatin (NDP) with compound 14a (6 μmol/L) were significantly higher than those treated by NDP alone. Compound 14a (30 μmol/L) significantly inhibited the migration (both P<0.01) and induced the apoptosis of HeLa or SiHa cells (both P<0.01). Conclusions σ1R is over-expressed in cervical cancer and HSIL. σ1R nuclear expression is an important marker of AC. σ1R over-expression, especially σ1R nuclear expression is associated with the poor prognosis of cervical cancer. Our study is mostly consistent with cervical cancer data of TCGA. These results suggest that the novel synthetic prezamicol analogues 14a for σ1R could inhibit the growth of cervical cancer cells and cell migration through inducing apoptosis and arresting cell cycle in G0/G1 period, enhance NDP-induced cytotoxicity.
