Objective To evaluate four tumor markers of insulin-like growth factor 1((IGF-1), CEA, cytokeratin fragment antigen 21-1 (CYFRA21-1), neuron-specific enolase (NSE) for the diagnosis and prediction of treatment response in human lung cancer. Methods Serum samples were taken from three groups: 91 patients with lung cancer, 30 healthy adults and 15 patients with benign pulmonary diseases. Serum IGF-1 was assayed by radioimmunoassay and CEA, CYFRA21-1, and NSE by electrochemiluminescence immunoassay. The differences among the three groups were determined by Kruskal-Wallis one-way analysis of variance (ANOVA) and with Mann-Whitney rank-sum test. Diagnostic efficacy was evaluated by ROC curves. Results The four serum tumor marker levels were significantly higher in lung cancer group, as compared with the benign and the healthy (IGF-1:χ2=26.95,P<0.001, CEA:χ2=49.11,P<0.001; CYFRA21-1:χ2=40.63,P<0.001; NSE:χ2=14.76;P<0.001). The diagnostic sensitivities of IGF-1, CEA, CYFRA21-1 and NSE was 75.6% (34/45), 53.3% (24/45), 66.7% (30/45) and 42.2% (19/45) respectively for lung cancer. The diagnostic sensitivity of IGF-1 combined with CYFRA21-1 was 95.5 %( 43/45) and that of IGF-1 combined with CEA and CYFRA21-1was 97.8%(44/45). Only IGF-1 and CYFRA21-1 showed significant changes before and after treatment (IGF-1: χ2=5.99,P=0.014; CYFRA21-1:χ2=4.99, P=0.025) in cancer group. Conclusions Serum IGF-1, CEA, CYFRA21-1 and NSE are all valuable for lung cancer diagnosis and the combination of those parameters can enhance the diagnostic efficiency. Serum IGF-1 and CYFRA21-1 may also be useful for evaluating the treatment response in lung cancer.

Analyzed in this paper is the feasibility to carry out rural area-oriented remote medical education and to establish the remote medical education center by making use of the advantages in medical colleges and universities according to the medical and health situation and the requirement of remote medical education in rural areas, which was followed by some suggestions put forward for how to effectively run the remote medical education center with the poor medical conditions and few opportunities for rural medical staff to improve their medical care level taken into consideration.

Effect of ginsenoside total saponin (GTS) on the regulation of P450 of livers of rats after γ-ray irradiation was studied. Rats were irradiated by the ⁶⁰Coγ-ray for one-time dose of 5.5 Gy, dose rate of 117.1-119.2 cGy. The cocktail probe, qPCR and Western blot were used to detect expression of enzymatic activites, mRNA and protein of rats. Contrasted with blank group, expression of CYP1A2, 2B1, 2E1, 3A4 of irradiation group showed a up-regulated (P < 0.05). Contrasted with irradiation group, exprression of CYP1A2, 2B1, 2E1, 3A4 of GTS group showed a downward trend. GTS had negative agonistic action against expression of P450 of rats by irradiatied.

Objective To investigate the relationship between cognitive function and emotional status in functional constipation patients.Methods Thirty-five functional constipation patients (the functional constipation group) and 24 healthy controls (the HCs) were enrolled in an event-related potential (ERP),behavior and electroeneephalogram study while performing an oddball auditory task.Response time,accuracy,latency and P300 amplitude were compared between the two groups.The Hamilton depression rating scale (HAMD-17),Hamilton anxiety scale (HAMA),symptom check list-90 (SCL-90) and Eysenck personality questionnaire (EPQ) were administered prior to the oddball task.Results The average HAMD-17,HAM A and SCL-90 (the somatization,obsessive-compulsive disorder,depression,anxiety and psychosis dimensions) scores of the functional constipation group differed significantly from those of the HCs.The intro-extraversion and neurosis dimensions of the EPQ were also significantly different.There was no significant difference in response time or latency between the two groups.The ERP results showed that the P300 amplitudes at the F3 and F7 sites were significantly different between the functional constipation group and the HCs.But there was no significant difference in P300 latencies at F3 or F7 between the two groups.Conclusions The findings suggest that patients with functional constipation are more susceptible to depression and anxiety,as well as somatization,obsessive-compulsive tendencies and other neurotic personality characteristics.Patients may employ psychological defense mechanisms to avoid the depression and anxiety.The ERP results imply there may be the implicit cognitive dysfunction with emotion in patients with functional constipation.

One hundred and twenty stroke patients were randomly divided into rehabilitation group (n =60) and control group (n =60).Patients were assessed with National Institute of Health Stroke Scale (NIHSS) ,Fugl-Meyer Assessment (FMA),Bathel Index (BI) and World Health Organization Quality of Life Assessment Instrument Brief Version(WHOQOL-BREF) before and 6 weeks after treatment by the same doctor.The scores of NIHSS,FMA,BI and WHOQOL-BREF were improved significantly in rehabilitation group after treatment; while those of control group were no improved.The scores after treatment of rehabilitation group were significantly higher than those of control group ( P ＜ 0.05 ).

Objective To investigate the change of cardiac function in elderly hypertensive patients with heart valve degenerative by echocardiography.Methods A total of 126 cases were divided into a valve disease group and non-valve disease group groups.The parameters of trial size,cardiac function and pulmonary artery pressure were detected.Results Of all 126 cases were the patients with hypertension including 28.6% (36/126) of valve disease group and 71.4% (90/126) of non-valve disease.There were 31 cases with mitral valve disease,22 cases with tricuspid valve disease; 26 cases with aortic valve disease; 36 cases with double or three alvular lesions in valve disease group.There was a significant difference in ventricle size and systolic function among valve disease group and non-valve disease group and control group.But there was no significant difference in thickness of ventricular wall between valve disease group and non-valve disease group.Conclusion The elderly hypertensive patient with valve disease was an independent factor for the development of congestive heart failure.

Objective To observe the dynamic changes of interferon gamma(IFN-?) and transforming growth factor bata1(TGF-?_1) in animal model of hyperoxia-induced lung injury,and to explore the mechanism of fibrosis.Methods Thirty-two juvenile Wistar rats were randomly divided into room-air group and hyperoxia group,the hyperoxia group were further divided into 3 subgroups of hyperoxia-exposure for 3,7 and 14 days.The mRNA levels of IFN-? and TGF-?_1 in the lung were measured by reverse-transcription polymerase chain reaction(RT-PCR).The expressions of IFN-? and TGF-?_1 protein were measured by immunohistochemical(stai)-ning.Results The level of IFN-? mRNA of groups under hyperxia-exposure for 3,7 and 14 days were higher than that of control group.The expression of IFN-? mRNA notably elevated and was up to its peak(P
