Objective To investigate the expressions of ?-catenin(?-cat)and ?-catenin(?-cat)and their relation with development and prognosis of non-small cell lung cancer(NSCLC).Methods Expressions of ?-cat and ?-cat were immunohistochemically studied in 43 specimens of NSCLC and 7 cases of normal lung tissues.Results Of the 43 NSCLC cases,the abnormal rate of ?-cat and ?-cat expression was 72.1% and 65.1%,respectively.Differentiation and lymph node involvement had a significantly positive correlation with abnormal expression of ?-cat or ?-cat(P

Objective To investigate the efficacy of docetaxel combined with capecitabine in the treatment of patients with locally advanced breast cancer and its effect on immune function.Methods 160 patients with locally advanced breast cancer were randomly divided into observation group and control group.The control group was treated with capecitabine.The patients in the observation group were treated with docetaxel combined with capecitabine.The clinical effective rate, median time to progress, median survival time, one year survival rate and immunoglobulin protein expression levels were observed.Results The clinical effective rate and stable rate in the observation group were 88.75% and 95.00%, which were significantly higher than 68.75% and 87.50% in the control group, the differences were statistically significant (x2=5.89,4.17,all P<0.05).After treatment, the median time to progression, median survival time and one year survival rate of the observation group were significantly higher than those of the control group (t=3.43,5.09,6.23,all P<0.05).Compared with before treatment, after treatment, the IgG,IgM and IgA levels in the observation group significantly decreased(t=2.34,3.16,3.27,all P<0.05), while those of the control group were not significantly changed (t=0.79,0.22,0.27,all P>0.05).Conclusion Docetaxel combined with capecitabine in the treatment of patients with locally advanced breast cancer can improve the clinical efficacy and stability, prolong the survival time of patients.Compared with using single agent chemotherapy, combined use has no significant effect on human immune function, the effect is better than the use of capecitabine alone, which is worthy of promotion in clinical use.

Objective To investigate the anesthetic action of intraperitoneal (i.p.) emulsified isoflurane and determine ED50 and LD50 in rats. Methods One hundred and thirty SD rats aged 6-8 weeks veighing 120-150 g were randomly divided into three groups: (A) control group ( n = 10) ; (B) ED50 group ( n = 60) ; (C) LDSO group (n = 60) . Group B and C were further divided into 6 subgroups with 10 animals (5 male, 5 female) in each subgroup. In control group a single bolus of 30% emulsified fat 2ml/100g body weight was administered i. p. In ED50 group a single bolus of 2.30% -6.0% vol/vol emulaified isoflurane 1.5 ml/100 g was administered i. p. and righting reflex was recorded. In LD50 group a single bolus of 4.09% - 10.64% vol/vol emulsified isoflurane 2 ml?100 g-1 was given i.p. and toxic response and lethal dose were recorded. The concentration ratio of the two neighbouring subgroups was 1:0.825. Results The ED50 of emulsified isoflurane was (0.57?0.07) ml.kg-1 and 95% confidence limit (CL) was (0.51-0.64)ml?kg-1 . The average onset time of action was (2.64 ?0.99) min and the average duration of action was (28 ? 11) min. The LD50 of emulsified isoflurane was (1. 26 ?0.10) ml?kg-1 and 95% confidence limit was 1.10-1.45 ml?kg-1 . The therapeutic index (LD50/ED50)was 2. 24. Conclusion Intraperitoneal emulsified isoflurane can provide effective general anesthesia and can be used for animal experiments which need anesthesia of short duration.

Objective To observe the efficacy and safety of oxycontin treatment in cancer patients with mod-erate to severe chronic cancer pain.Methods This study was performed by study group and control groups.120 cases of patients with moderate to severe chronic pain were enrolled in study group and treated with oxycontin(10mg/time, once every 12 hours).50 cases of patients with moderate to severe chronic pain were randomly allocated to control group and treated with tramadol hydrochloride sustained-release tablets(100mg/time,once every 12 hours).Clinical efficacy and adverse reactions of patients in the study group and control group were evaluated after therapy for three weeks.Results There was 35 cases of complete remission,80 cases of partial remission,and 5 cases of mild remis-sion,and the overall response rate was 95 .8% in the study group.In addition,there was 4 cases of complete remis-sion,4 0 cases of partial remission,4 cases of mild remission and 2 cases of no effect,and the overall response rate was 88.0%,there was statistically significant difference(P=0.004).Meanwhile,the rates of adverse reactions in the study group and the control group were 16.7% and 14.0%,respectively,there was no statistically significant differ-ence(χ2 =0.188,P>0.05 ).Conclusion Oxycontin can effectively safely treat cancer patients with moderate to severe chronic pain.

Objective To study the effect of surface electromyogram-triggered electrical stimulation on lower limb function in hemiplegic stroke patients. Methods Thirty hemiplegic stroke patients were divided into a treatment group ( 15 cases) and a control group ( 15 cases). Both groups were given conventional rehabilitation training.Additionally, the treatment group was given surface electromyogram-triggered electrical stimulation training, while the control group was given common low frequency electrical stimulation. Brunnstrom's recovery stages, the Fugl-Meyer assessment (FMA) and electromyographic parameters were assessed before and after 3 courses of treatment. Results After treatment both groups had significantly higher Brunnstrom and FMA scores and better integrated electromyograms(iEMG), but the effects in the treatment group were significantly better than in the control group. Conclusions Surface electromyogram-triggered electrical stimulation training can provide satisfactory rehabilitation of lower limb function in hemiplegic stroke patients.

A metabonomics method based on gas chromatography_mass spectrometry ( GC_MS) was developed for detecting the significant differences of root exudates of the Cd hyperaccumulator Sedum alfredii under different treatments and study the effect mechanism of S. alfredii tolerating or accumulating the heavy metal Cd. The root exudates were collected after treatment for 4 and 8 days with 0 and 40μmol/L Cd. The collected solution was lyophilized and dissolved with methanol, and after derivatization with methoxyamine hydrochloride and N_methyl_N_trifluoroacetamide, the samples were analyzed by GC_MS. Principal component analysis ( PCA) and orthogonal partial least_squares discrimination analysis ( OPLS_DA) were carried out for pattern recognition and a clear separation among the different treatments was achieved. Twelve compounds which caused the separation among the different treatments were found and identified. With the change of treatments, the relative amount of these 12 compounds revealed different trends, which indicated that the Cd hyperaccumulator S. alfredii could adjust the secretion of root exudates to tolerate or accumulate the heavy metal Cd.

Objective To investigate the pathophysiology mechanism in belching by using high resolution manometry combined with impedance monitoring.Methods Ten belching patients (four male and six female,ages ranged from 28 to 50 years) received high resolution manometry combined with impedance monitoring.The characters of esophageal motility at rest,swallowing and belching and the possible mechanism of belching were analyzed.Results Nine of 10 patients had esophageal peristaltic dysfunction,displaying as non-peristaltic contraction such as non-conduction contraction,interrupt contraction and dropping contraction.The pressure of the lower esophageal sphincter (LES) of three patients decreased.LES of one patient had incomplete relaxation.Nine of 10 patients were supragastic belching,in which air moved rapidly into esophagus and reversed exited from the mouth in one second.Among nine supragastic belching patients,the pleural pressure of seven patients increased during inspiration,upper esophageal sphincter relaxed and air was mistaken into the esophagus.The pharyngeal muscle contracted in two patients and the air was forced into esophagus.Of all the patients,intragastric and esophageal pressure increased through abdominal muscles and diaphragm contraction and air exited from the mouth.Conclusions The results of this study indicated that there was esophageal peristaltic dysfunction in belching patients.There was no frequently air swallowing in excessive belching patients,the typical belching model was supragastic belching.

OBJECTIVE:To study the distribution characteristics of germacrone from zedoary turmeric oil (ZTO) in each tis-sue of mice,and to provide reference for further application of zedoary turmeric oil. METHODS:30 KM mice were given zedoary turmeric oil 0.5 mL;6 mice were randomly selected 1,2,4,8,12 h after medication,respectively. The contents of germacrone in heart,liver,spleen,lung and kidney tissues were determined by HPLC. 15 KM mice were selected,medication and sampling method were same as above;3 mice were collected at each time point respectively. The fluorescence intensity of germacrone in above sections were observed by fluorescence. The same number of mice were selected as control in 2 trials. RESULTS:The con-centration of germacrone in each tissue 1-4 h increased gradually as time and reached the peak value at 4 h. The contents of ger-macrone in liver and spleen were significantly higher than in heart and lung. The concentrations of germacrone in each tissue were ranked as liver>spleen>kidney>heart>lung. The results of fluorescence intensity observation was same as above results. CON-CLUSIONS:Results of 2 methods show same distribution characteristics of germacrone in mice tissues,and indicate that ger-macrone is distributed more in liver,spleen and kidney tissues and less in heart and lung.

Objective:To understand the cognitive differences and its influential factors of medical dispute and physician′s professionalism between medical personnel and patients, and further to provide evidence for the preven-tion and treatment of medical dispute. Methods:In the case of quality control, we surveyed on the cognitive of medical dispute and physician′s professionalism in medical personnel and patients using self-designed question-naire. Stratified cluster sampling method was used in this study, which recruited 847 medical workers and 577 pa-tients. Data analysis was conducted with SPSS 16. 0. The two sample rates were compared using Chi squaretest (α=0. 05). Results:There is a statistically significance in doctor-patient relationship evaluation, dispute pre-vention, dispute responsibility, fair treatment,impact on the doctors and patients, causes of medical disturbance, attitude tomedical disturbance, medical disturbance elimination, physician′s professionalism evaluation, improve-ment approach, and the physician′s professional value between the two samples, having a direct impact on the con-struction of physician′s professionalism. Conclusion:For medical personnel, they should strengthen the construc-tion of physician′s professionalism and establish effective mechanism to prevent medical dispute. For patienes, they should understand, trust and respect the doctors, and solve medical dispute rationally. For government, they should establish a reasonable mechanism for the settlement of medical dispute, create a rational atmosphere respon-ding to the medical dispute, and reduce the intensification of medical dispute.
