Objective To analyze the function of let-7e in the carcinogenesis of non-small-cell lung cancer.Methods The microRNA let-7e expression levels in cancer tissues and adjacent normal lung tissues were detected by quantitative real-time reverse transcription-PCR from 35 non-small-cell lung cancer patients,U6 RNA as an actin.Results The expression of microRNA let-7e in cancer tissues was significantly higher than adjacent normal lung tissues (10.111±6.135,P ＜ 0.0001),there was a significantly different between squamous carcinoma group (9.635±8.300) and adenocarcinoma group (10.301 ±5.228,P ＜ 0.05),independently of sex,smoking history,stage,and histologic characteristics of the tumor.Conclusion The expression of microRNA let-7e in cancerous tissues is high,microRNA let-7e should play oncogene role in process of non-small-cell lung cancer,and would be an useful biomarker.

Objective: To explore influence of exercise on cardiac autonomic nerve function in patients undergoing coronary artery bypass grafting (CABG) and its clinical significance. Methods: A total of 53 patients with coronary heart disease undergoing CABG were randomly divided into routine treatment group (n=25) and rehabilitation group (n=28, received exercise training based on routine treatment). Changes of autonomic nerve function before, second and eighth week after CABG were analyzed in two groups using time domain indexes of heart rate variability (HRV) by ambulatory electrocardiography, including standard deviation of normal to normal RR intervals calculated over the 24 h period (SDNN), standard deviation of normal to normal RR intervals in all 5 min segments of the entire recording (SDANN), root-mean square of differences between successive normal to normal intervals (rMSSD) and adjacent normal RR interval difference > 50ms stroke accounted for a percentage of 24h total RR interval (PNN50). Results: Compared with before CABG, there were significant decrease in SDNN, SDANN, RMSSD and PNN50 in both groups two weeks after CABG (P<0.05~0.01); eight weeks after CABG, above indexes recovered to levels before CABG in routine treatment group[SDNN （113.6±29.4）vs.（116.7±24.7）, SDANN（112.2±32.1）vs.（113.6±28.6）, rMSSD（21.9±8.2） vs.（23.2±7.1）, and PNN50 （7.5±4.2）vs.（8.2±3.7）] , P>0.05 all; Compared with before CABG, there were significant improvements in SDNN [(114.7±25.2) ms vs. (132.6±30.6) ms], SDANN [(111.6±23.5) ms vs. (129.2±30.8) ms], rMSSD [(24.2±8.7) ms vs. (29.9±7.5) ms] and PNN50 [(7.8±2.2) ms vs. (9.5±2.3) ms], and there were significant improvement than those of routine treatment group [SDNN （132.6±30.6）vs.（113.6±29.4）, SDANN（129.2±30.8）vs.（112.2±32.1）, rMSSD（29.9±7.5）vs.（21.9±8.2）and PNN50 （9.5±2.3）vs.（7.5±4.2）] eight weeks after CABG in rehabilitation group, P<0.05 all. Conclusion: All HRV indexes significantly decrease on two weeks after CABG in both groups, suggesting that CABG can damage cardiac autonomic nerve system. These indexes of rehabilitation group were more improvement than those of routine treatment group, suggesting exercise training can more significantly improve cardiac autonomic nerve function after CABG.

Objective To reveal evolution characteristics and antigenic epitope variabilities of hemagglutinin (HA) gene of H3N2 viruses in Guangdong during 2014-2015.Methods The HA gene nucleotide sequence of influenza H3N2 virus isolated during 2014-2015 in Guangdong Province was selected by spatial-temporal distribution.The HA gene nucleotide sequences were compared with global HA genes downloaded from GenBank and GISAID and the gene nucleotide mutations were analyzed.The phylogenetic tree and the entropy chart were conducted.Results Compared with HA gene of vaccine strain A/Texas/50/2012,the substitutions of 25 amino acid sites occurred in the HA gene of the 17 Guangdong strains during 2014 to 2015.The epitope A,B,D and E of the HA1 gene developed mutations,which involved 11 amino acid sites.One glycosylation site deletion occurred in A/Guangdong/ 55/2015 in virtue of the N38K site mutation.The high mutation site was at 175 with entropy value of 1.16.The 363 site might be the positive selection while the 368 and 425 sites might be the negative selection sites by comprehensive evaluation of the screening results of the single likelihood ancestor countincy (SLAC),fixed effects likelihood (FEL) and internal fixed-effects likelihood (IFEL) model.Conclusions The mutations emerge in the epitopes A,B,D and E of HA gene of the Guangdong H3N2 stains.Evolution at 363 site is positive selection while those at 368 and 425 sites are negative selection.The mutation accumulation might lead to the epidemic of influenza H3N2.

Pre-and post-operative blood flow rates of cone were recorded by color doppler.Results Ultrasound was the same as computer tomography not only presented the image of anatomy and pathology of TCS,but also showed the lack of pulsatile motion of distal cord with TCS.Before the operation,blood flow rates of cone were( 0.047?0.012) m/s.After the operation,blood flow rates of cone were(0.158?0.029) m/s.There was significantly different(P

The effects of Guizhi Fuling capsule and its active ingredient combination within different concentration on SPL proliferate were observed by MTT method. The ratio of CD80/86, CD3CD25 and CD3CD69 was used to evaluate cell activation effects of Guizhi Fuling capsule and its active ingredient combination by FCM. Guizhi Fuling capsule with concentration of 400 mg · L(-1)can promote spleen lymphocyte proliferation, as well as the active ingredient combination, which showed the obvious dose-effect relationship. Compared with control group, the difference has statistical significance (P≤0.01). The result of FCM showed that Guizhi Fuling capsule and its active ingredient combination can promote CD80 and CD86 expression on spleen lymphocyte, and also can increase CD25 and CD69 ratio between spleen CD3+ cells. Compared with control group, the difference has statistical significance (P≤0.01). Thus, Guizhi Fuling capsule and its active ingredient combination may have immune-modulate effects, and the mechanism may have a close relationship with the lymphocyte activation.

BACKGROUND: Huperzine A is a reversible cholinesterase inhibitor extracted initially by China from huperzia serrata,a Chinese herb. Its mechanism in improving choline function and ameliorating cognitive state of patients with dementia is to increase acetylcholine (Ach) concentration in neural synapse through impeding the hydrolysis of acetylcholinesterase.OBJECTIVE: To investigate the effects of huperzine A on the improvement of cognitive function of patients with Alzheimer disease (AD).DESIGN: A randomized controlled study based on patients.SETTING: Second internal department of neurology in a general hospital of military area command of Chinese PLA.PARTICIPANTS: Totally 69 AD patients hospitalized in the Second Department of Neurology,General Hospital of Jinan Military Area Command of Chinese PLA between March 2000 and December 2003 were allocated into huperzine A group( n = 38,male,aged between 68 and84 years old,average age of 76 years old) and control group( n = 31,male,aged between 68 and 80years old,average age of 74 years old) according to the wills of the patients.MAIN OUTCOME MEASURES: Positive expression percentage of Fas,Apo2.7 and Bcl-2 on platelet membrane and the integral of mini-mental state examination(MMSE),Hasegawa' s dementia scale(HDS) and activities of daily living (ADL) of two groups after therapy.RESULTS: The positive expression of Fas,Apo2.7 or Bcl-2 on peripheral platelet membrane after therapy in huperzine A group were (2.23 ± 0.49)%,(2.37 ±0. 36)%,or(2.01 ±0. 32)% respectively,which was significantly lower than(3.12 ± 0. 74)%,(2. 83 ± 0.67)% or (2. 59 ± 0. 54)% of control group ( P ＜ 0.01). The prognostic integral of MMSE,HDS or ADL of huperzine A group was 20.45 ±4. 14,21.39 ±4.89,or 36. 15 ±5.11,which was significantly higher or lower than that of the control group(15.76 ± 3.23,17.32 ±2.09,4.26 ±7.21)(P ＜ 0.05).CONCLUSION: HuperzineA actually can effectively improve the memory and cognitive function of AD,and effectively improve ADL as well.

Objective To investigate the value of magnetic resonance imaging(MRI)in the evaluation of microwave ablation(MA)for liver cancer.Methods The clinical data of 51 patients with liver cancer who received MA at the General Hospital of PLA from November 2005 to June 2009 were retrospectively analyzed.The MRI findings of 65 nodules before and after the treatment of MA were evaluated by serological examination and needle biopsy of liver.Results All patients received MRI within 1 month after MA.Of all nodules.63 were presented with high signal intensity on T_1-weighted images(T_1 WI)and low signal intensity on T_2-weighted images (T_2 WI)and with peripheral ring-like enhancement.They were diagnosed as complete coagulation necrosis,and the alpha-fetoprotein(AFP)level of the patients decreased from 333.83μg/L before MA to 37.68 μg/L after MA.Two nodules were presented with low signal intensity on T_1 WI and high signal intensity on T_2 WI,and they were diagnosed as local residual.All patients were followed up l month after MA,and 5 nodules showed enhancement with the same image characteristics as local residual.They were diagnosed as local recurrence of liver cancer by needle biopsy of liver and AFP level detection.New intrahepatic nodules in 23 patients and an abdominal nodule in 1 patient were detected with an increase of AFP level(mean,120.16 μg/L).Conclusion MRI Can exactly evaluate the efficacy of MA in the treatment of liver cancer.

Objective To investigate the relationship between the level of circulating CD133+/KDR+ endothelial progenitor cells (EPCs) and outcome in patients with acute ischemic stroke.Methods Inpatients with first-ever ischemic stroke within 24 hfrom the onset and age-and sex-matched healthy subjects were enrolled in the study.The demographic and clinical data of the patients were collected.The level of CD133+/KDR+ EPCs was detected by flow cytometry.All patients were followed up at 90 d.The modified Rankin Scale was used to evaluate the clinical outcome,0-2 was defined as good outcome and >2 was defined as poor outcome.Results A total of 126 consecutive patients with first-ever ischemic stroke within 24 hfrom the onset and 60 age-and sex-matched healthy subjects were enrolled.In patients with ischemic stroke,33 (26.19%) were large artery atherosclerosis (LAA),74 (58.73%) were small artery occlusion (SAO),19 (15.08%) were cardioembolism (CE);82 (65.08%) had good outcomes and 44 (34.92%) had poor outcomes.The number of circulating EPCs at baseline in patients of the LAA subtype (0.071%±0.018%),CE subtype (0.068%±0.16%) and SAO subtype (0.118%±0.12%) was significantly lower than that in the control group (0.246%±0.052%;all P<0.05),and the CE subtype (P=0.028) and LAA subtype (P=0.037) were significantly lower than the SAO subtype;the CE subtype was lower than the LAA subtype,but the difference was not statistically significant (P=0.762).The proportions of patients with LAA subtype (40.91% vs.18.29%;χ2=7.577,P=0.006) and CE subtype (29.55% vs.7.32%;χ2=11.049,P=0.001) and atrial fibrillation (29.55% vs.10.98%;χ2=6.582,P=0.009),and age (69.64±9.62 years vs.61.12±7.31 years;t=5.570,P<0.001),and baseline NIHSS score (14.16±4.22 vs.6.96±2.04;t=12.919,P<0.001),baseline systolic blood pressure (176.06±13.42 mmHg vs.164.12±11.69 mmHg,1 mmHg=0.133 kPa;t=5.187,P<0.001),low-density lipoprotein cholesterol (2.92±0.52 mmol/L vs.2.49±0.36 mmol/L;t=5.447,P<0.001),fasting blood glucose (8.76±2.88 mmol/L vs.6.82±2.24 mmol/L;t=4.185,P<0.001),C-reactive protein (7.62±1.82 mg/L vs.4.57±1.58 mg/L;t=9.790,P<0.001),and D-dimer (1.14±0.08 mg/L vs.0.97±0.22 mg/L;t=4.946,P<0.001) levels in the poor outcome group were significantly higher than those in the good outcome group,while the proportion of the SAO subtype patients (29.55% vs.74.39%;χ2=23.759,P<0.001),high-density lipoprotein cholesterol (0.94±0.68 mmol/L vs.1.16±0.14 mmol/L;t=2.829,P=0.005),and baseline EPCs (0.069%±0.018% vs.0.098%±0.021%;t=7.755,P<0.001) were significantly lower than those in the good outcome group.Multivariate logistic regression analysis showed that the higher baseline NIHSS score (odds ratio 1.242,95% confidence interval 1.126-1.372;P<0.001),CE subtype (odds ratio 3.460,95% confidence interval 1.312-5.146;P=0.016),and the lower baseline EPCs (odds ratio 1.632,95% confidence interval 1.006-3.024;P<0.001) were the independent risk factors for poor outcome in patients.Conclusion s The level of circulating EPCs was decreased significantly in patients with acute ischemic stroke,and the lower level of baseline EPCs was an independent predictor of poor outcome in patients with ischemic stroke at 90 d.

OBJECTIVE: To repair the postoperative tissue detect of the base of tongue cancer in advanced patients. METHOD: There were 30 patients of medium-high differentiation squamous cell carcinoma(SCC) included in this study. According to the TNM staging of AJCC 2002, there were 4 cases of T2N1M0, 7 of T3N1M0, 10 of T3N2M0, 4 of T4N1M0 and 5 of T4N2M0. Surgical approach of the primary lesion: 12 with transhyoidpharyngotomy approach and 18 with mandibulotomy approach. All cases accepted radiotherapy 4-6 weeks after surgery. RESULT: Twenty-five cases were reconstructed with pedicle pectoralis major myocutaneous flaps, and all them survived. Among them, 1 flap was partial split with surrounding tissue spontaneously, and another flap had partial tissue necrosis, however, both flaps grew well with dressing and other local treatment. Other 5 cases were reconstructed with free anterolateral myocutaneous flaps. Among them, 1 flap had partial tissue necrosis, but had a secondary healing after removing necrotic tissue via mouth approach. All 18 patients of larynx-preservation had tracheal tube pulled out. The 3-year survival rate was 68% and the local control rate was 87%. CONCLUSION Pedicle pectoralis major myocutaneous flaps and free anterolateral myocutaneous flaps were alternative donor area for repairing postoperative tissue defect of the base of tongue; The former was preferred, and the latter was concealed so as to be a kind of effective method, which need adept technique of microsurgery.

A method of comprehensive chemical pattern recognition of Atractylodis Rhizoma was established by GC-MS fingerprint, principal component analysis, cluster analysis and discriminant analysis. A DB-wax column (0.25 mm x 60 m, 0.25 microm) with El ion source and 70 V electron multiplier were used for GC-MS analysis. Using principal component analysis, cluster analysis, and discriminant analysis, 15 common peaks of sample fingerprints for chemical pattern recognition research were analysed. The same results were obtained from the fingerprint, principal component analysis and cluster analysis, which could use to distinguish genuine Atractylodes lancea, ungenuine A. lancea and A. chinensis. Thus, this method could be used for the quality control and comprehensive evaluation of Atractylodis Rhizoma.
