Lung is one of the most sensitive target organs of human beings under the shock waves. Due to its serious injury, rapid development and high mortality, blast lung injury has been a widely concerned research topic in the field of military medicine. In the normal physiological state, the body is in a dynamic balance between pro-inflammaton and anti-inflammation, oxidation and anti-oxidation, promoting apoptosis and inhibiting apoptosis. While blast lung injury breaks the balance and causes physiological, biochemical and pathological changes in the body, seriously leading to acute respiratory distress syndrome and multiple organ dysfunction syndrome, and eventually the mortality. So far, the researches on blast lung injury mainly involve damage model, pathogenesis, pathological changes, intervention treatment and so on, which has achieved great research findings. In the review, the authors summarize the progress of molecular mechanism for blast lung injury from the perspective of inflammatory reaction, oxidative stress, apoptosis and so on, which may promote the discovery of new targets for the diagnosis, treatment and rehabilitation intervention of blast lung injury.

Objective: To examine the impact of metabolic syndrome (MS) on the clinicopathological characteristics and prognosis of patients with colorectal cancer (CRC). Methods: The clinical data of 650 patients with CRC admitted in Shanxi Provincial Cancer Hospital between January 2010 and December 2011 were retrospectively analyzed. Among 650 patients there were 190 cases complicated with MS (MS group) and 460 cases without MS (non-MS group), the clinicopathological features and prognosis were compared between two groups. Results: The serum insulin and insulin-like growth factor-1 (IGF-1) levels in MS group were significantly higher than those in non-MS group [(9.2±4.7) vs.(6.8±4.7)μIU/L, t=8.88, P<0.01 and (200.2±44.1) vs.(136.7±63.2)mg/L,t=12.63, P<0.01]. The proportions of stage T₃ and T₄ cancer, extra-regional lymph node metastasis (ELN), and TNM stage Ⅲ and Ⅳ patients in MS group were significantly higher than those in non-MS group [(83.2% (158/190) vs. 72.6% (334/460), χ²=8.19, P=0.04; 9.5% (18/190) vs. 4.8%(22/460),χ²=8.61, P=0.04; 56.3% (107/190) vs. 45.2%(208/460), χ²=8.22, P=0.04, respectively]. The 5-year disease-free survival (DFS) in MS group was significantly lower than that in non-MS group [57.9%(99/171)vs. 66.1%(279/422), P<0.01]. Multivariate analysis indicated that MS(HR=1.623, 95%CI:1.511-1.963, P=0.03), IGF(HR=1.382, 95%CI:1.031-1.765, P=0.02) and, ELN(HR=4.270, 95%CI:2.177-7.463, P<0.01)were independent factors affecting the prognosis of CRC patients. Conclusion Metabolic syndrome is one of the risk factors affecting the prognosis of CRC patients.

Objective To investigate the value of detecting peripheral blood epidermal growth factor receptor (EGFR) gene in predicting the therapeutic efficacy of advanced non-small cell lung cancer. Methods A total of 150 patients with stage ⅢA-Ⅳ non-small cell lung cancer diagnosed in Shanxi Provincial Cancer Hospital from October 2013 to February 2015 were collected. The peripheral blood EGFR gene was detected by amplification refractory mutation system (ARMS). The relationship between the mutation rate and the clinicopathological features of patients was observed, and 80 patients were selected into the follow-up treatment according to the inclusion criteria. Forty patients (all 19 or 21 exon mutations) in group A with EGFR gene mutation were treated with gefitinib orally. Forty patients with wild type EGFR gene in group B underwent 4 cycles of NP regimen. Efficacy and progression-free survival were evaluated in both groups. Results The mutation rate of EGFR gene was 33.3 ％ (50 cases), of which 29 were exon 19, 18 were exon 21 and 3 were exon 18 and 20. The mutation rate of EGFR gene was higher in female, adenocarcinoma and non-smoker (all P<0.05). Among the 80 patients who received follow-up treatment, the effective rate [67.5％(27/40) vs. 32.5 ％ (13/40)] and disease control rate [85.0 ％ (34/40) vs. 65.0 ％ (26/40)] in group A were significantly higher than those in group B, and the median PFS was prolonged (9.00 months vs. 4.25 months),the differences were statistically significant (χ2=9.800, P=0.002;χ2=4.267, P=0.039;χ2= 15.792, P<0.001). Conclusion The detection of peripheral blood EGFR mutation can be used to predict the efficacy of tyrosine kinase inhibitors in non-small cell lung cancer.

Objective To investigate the value of magnetic resonance diffusion-weighted imaging (DWI) in combination with peripheral serum tumor markers in the diagnosis and therapeutic evaluation of small cell lung cancer (SCLC) brain metastases.Methods Retrospective analysis of 368 SCLC cases diagnosed by histopathology or cytology from February 2009 to February 2012 in Shanxi Provincial Cancer Hospital was made.All patients underwent pathological examination of progastrin-releasing peptide (ProGRP),neuron-specific enolase (NSE) and brain DWI,and measured the apparent diffusion coefficient (ADC) of DWI sequences of brain metastases.The difference between the positive rates of ProGRP and NSE in patients with or without brain metastases was compared by the X2 test,and the diagnostic efficiency of ProGRP,NSE,DWI and combined detection for brain metastases were analyzed.The Kruskal-Wallis H test was used to compare the changes of ADC value,ProGRP and NSE before and after brain irradiation therapy in brain metastases of SCLC.Pearson correlation analysis was made to evaluate the correlation between the changes of ADC value and the levels of ProGRP and NSE in SCLC patients with brain metastases before and after treatment.Results The median expression of serum ProGRP in 169 SCLC patients was 2 664.7 pg/ml (98.4-4 876.8 pg/ml),with a positive rate of 98.2 ％ (166/169).The median expression of NSE was 41.9 μg/L (9.4-264.3 μg/L),with a positive rate of 70.4 ％ (119/169).The median expression of serum ProGRP level was 514.3 pg/ml (3.9-2 899.3 pg/ml) in 199 SCLC patients without brain metastasis,the positive rate was 89.4 ％ (178/199).The median expression of NSE was 40.4 μg/L (0.3-176.1 μ,g/L),with a positive rate of 64.8 ％ (129/199).The difference of ProGRP level between the two groups was statistically significant (u =121.47,P ＜ 0.001),but there was no significant difference in NSE level (u =1.35,P =0.12).The sensitivities of ProGRP,NSE,DWI,ProGRP+DWI and NSE+DWI were 68.4 ％,41.2 ％,66.7 ％,92.2 ％,and 82.4 ％,and the specificities were 52.9 ％,35.3 ％,76.5 ％,94.1％,and 88.2 ％.The sensitivity and specificity of ProGRP+DWI and NSE+DWI were higher than those of single test,and the differences were statistically significant (all P ＜ 0.001).One hundred and fifty-six SCLC patients with brain metastases were treated with whole brain radiotherapy.Pearson correlation analysis showed that ADC values were negatively correlated with ProGRP and NSE levels (r =-0.945,P ＜ 0.001;r =-0.995,P ＜ 0.001).Conclusion DWI combined with ProGRP and NSE can provide objective evidence and clinical guidance for the diagnosis of SCLC brain metastases and the evaluation of whole brain radiotherapy.

Objective: To investigate the effects and mechanism of Holothurian Glycosaminoglycan (hGAG) alone in combination with cisplatin (DDP) on apoptosis of pulmonary adenocarcinoma cell A549. Methods: A549 cells were separately treated with blank, hGAG, DDP and hGAG combined with DDP (hGAG + DDP). The cell morphology in 4 groups was observed using light microscope. CCK8 assay was used to determine the cell viability. Flow cytometry by Hoechst 33258 and AnnexinV-FITC/PI staining was applied to detect cell apoptosis. Western blot was then used to detect the protein expression of Bax, Bcl-2, survivin and caspase-3. Results: After treatment for 24 h, the inhibitory rates of A549 cells in control, hGAG, DDP and hGAG + DDP groups were 0, (19.74±5.39)%, (42.01±2.57)% and (53.89±4.58)%, respectively. Moreover, after treatment for 48 h and 72 h, the inhibitory rates in each group were 0, (23.17±4.78)% and (29.17±4.21 )%, (54.00±7.64)% and (59.35±7.31)%, as well as (77.58±4.26)% and (79.94±4.58)%, respectively. The cell viability was significantly lower in drug treatment groups compared with those in control group at the same time point (P<0.05). Hochest 33258 staining showed that no obvious apoptotic cells were detected in the control group, while apoptotic cells were visible in hGAG, cisplatin and combination groups. Flow cytometry showed that cell apoptotic rates were (2.38±0.59)%, (12.59±4.22)%, (16.36±3.63)% and (44.60±5.45)% in the control, hGAG, DDP and hGAG + DDP groups, respectively. The cell apoptosis was significantly lower in drug treatment groups compared with those in control group at the same time point (P<0.05). Furthermore, western blot results showed that the expression of Bax and caspase-3 protein was increased (P<0.05), whereas Bcl-2 and survivin was decreased (P<0.05) in the hGAG+ DDP group compared with cisplatin alone (P<0.05). Conclusions HGAG can inhibit the proliferation and promote the apoptosis of human lung adenocarcinoma A549 cells. Meanwhile, it can strengthen the chemosensitivity of A549 cells to DDP via up-regulation of Bax, caspase-3 and down-regulation of Bcl-2 and survivin.

Objective To investigate the apoptosis and toxicity of oncolytic virus H101 combined with radiation on apoptosis of A549 lung adenocarcinoma cells. Methods A549 lung adenocarcinoma cells in exponential growth phase were divided into four groups: control ( PBS) group, radiation ( IR) group, oncolytic virus (H101) group and radiation combined with oncolytic virus (IR+H101) group. The cells were double dyed with Annexin fluorescein isothiocyanate ( V-FITC/PI ) and then the apoptosis ratio of cells in every group was detected by the flow cytometry. The cytotoxic effect of cells in every group was detected by lactate dehydrogenase ( LDH) release test. The mRNA expression of oncolytic viruses H101 capsid protein Hexon was detected by real-time fluorescence PCR ( RT-PCR) to compare the oncolytic virus replication in each group. Results Cell apoptosis rate in H101 group (55. 37%) was significantly higher than that in PBS group (1.03%) (t =36.51, P <0.05). Cell apoptosis rate in IR + H101 group (93. 06%) was significantly higher than that in H101 group (55. 37%), IR group (12. 67%) and PBS group (1. 03%) (t=13. 51, 24. 14, 38. 99, P<0. 05). LDH releasing percentage in IR group and H101 group at different time after virus transfection was significantly higher than that in PBS group ( t=25. 84,39. 38, 32. 51, 78. 18, P<0. 05;t=31. 40, 2. 68, 23. 43, 60. 98, P<0. 05). LDH releasing percentage in IR+H101 group was significantly higher than that in PBS group (t=80. 71, 119. 74, 109. 80, 123. 94, P<0. 05), IR group (t=28. 80, 54. 34, 72. 34, 61. 91, P<0. 05) and H101 group (t=42. 02, 57. 45, 57. 01, 58. 83, P<0. 05). Compared with H101 group at the same time point, the mRNA expression of Hexon in IR + H101 group at 24, 48 and 72 h was increased by 16. 26, 28. 37 and 39. 58 times, respectively (t=54. 50, 33. 73, 29. 28, P<0. 05). Conclusions The oncolytic virus H101 plays a role of radiosensitization in tumor cells. Radiation also increases the replication of the oncolytic virus H101 and thereby enhances the oncolytic effect of the oncolytic virus H101. Therefore, oncolytic virus H101 combined with radiotherapy has synergistic effect on killing tumor cells.

Even though a large amount of researches showing the clinical effectiveness of acupuncture, there are the researches indicating the absent difference between acupuncture and sham-acupuncture (placebo), which provides the doubts on the specificity of acupuncture. It may be considered that acupuncture intervention is complica-ted and may produce unique non-specific effect, which results in the failure to evaluate effectively the acupuncture efficacy. The influential factors of the non-specific effect of acupuncture include the interaction between physician and patient, expectancy, physician authority, acupuncture treatment experiences, etc. It may be also relevant with the anticipated biological effect, Hawthorne effect, Pavlovian conditioned reflex, etc.

Objective To analyze the results of screening for tuberculosis (TB) in health examination participants and study the spontaneous occurrence of TB in the subjects with strong positive reaction to tuberculin skin test (TST) in ten years. Method Totally 12 598 health examination participants without past TB history were selected, of whom 8 896 were college students, 2 496 migrant workers and 1 206 had close contacts with active TB patients. They were screened by TST with strong positive reaction. All of subjects with TST strong positive results received chest X-ray examination and sputum acid-fast bacteria detection. The subjects diagnosed to have TB were given regularly anti-tuberculosis drugs treatment and followed up for ten years. The 429 subjects without TB and no isoniazid preventive treatment were chosen to be followed up for ten years and spontaneous occurrence of TB in first three years and the fourth to tenth years respectively, as well as the recurrence of TB for the patients who received anti-tuberculosis regimen were recorded. Result Thirty-seven cases were diagnosed as TB by TST screening, and the total detection rate was 0.29% (37/12 598). Among them 11 were college students (0.12%, 11/8 896), 12 were migrant workers (0.48%, 12/2 496) and 14 were close contacts (1.16%, 14/1 206) respectively. The detection rates were different among the three groups (χ2=31.40, P=0.000). Among 897 strong positive subjects, the strong positive rate was 7.12%(897/12 598), 316 were college students (3.55%, 316/8 896), 388 migrants workers (15.54%, 388/2 496), and 193 close contacts (16.00%, 193/1 206) respectively. There was significant difference in strong positive rate among the three groups (χ2=583.04, P=0.000), and the strong positive rate of college students was lower compared with that of the migrant workers and the close contacts (χ2=483.51 and 344.11, P<0.01). In ten years, 54 subjects were diagnosed as TB in 429 subjects with strong positive reaction to TST, the spontaneous cumulative incidence rate was 12.58% (54/429). Among them, the cumulative morbidity rate was 9.21%(14/152) in college students, 9.58%(18/188) in migrant workers and 24.72%(22/89) in close contacts respectively. The spontaneous morbidity rate of close contacts was higher than that of college students and migrant workers(χ2=10.63 and 11.21, P<0.001); 75 were lost in 398 participants, the dropout rate was 18.84%(75/398). In first three years of follow-up, 31 were diagnosed TB in 429 participants, the cumulative incidence rate was 7.23% (31/429). Of them 9 were college students (5.92%, 9/152), 10 migrant workers (5.32%, 10/188) and 12 close contacts (13.48%, 12/89) respectively (χ2=6.60, P=0.037). In the fourth to tenth years of follow-up, 23 were diagnosed TB in 398 participants, the cumulative incidence rate was 5.78% (23/398), which was not significantly different compared with the cumulative incidence rate of the first three years (χ2=2.50, P=0.37). Tirty-seven patients received standard anti-tuberculosis drug therapy for one year, no one of them had recurrence at ten-year follow-up. Conclusion The migrant workers and close contacts are the high-risk populations for TB. All of them with strong positive response to TST results are susceptible to TB. So regular physical examination is recommended for them and health management should be strengthened.
