In line with the new WHO definition for health and reference of comprehensive health assessments of elderly overseas, the paper screened and set the weight for comprehensive health assessment indicators for military officers, establishing a general health assessment model as a result 402 military officers were subject to Comprehensive Health Assessments, and the outcomes were compared with subjective assessment of experts. The results of both methods are highly coincidental. It proves Comprehensive Health Assessment as a scientific quantitative health assessment method, with promising perspectives in health management in the future.

BACKGROUNDRegulatory T-cells (Treg) play key roles in suppressing cell-mediated immunity in cancer patients. Little is known about perioperative Treg fluctuations in nonsmall cell lung cancer (NSCLC). Video-assisted thoracoscopic (VATS) lobectomy, as a minimal invasive procedure for treating NSCLC, may have relatively less impact on the patient's immune system. This study aimed to observe perioperative dynamics of circulating Treg and natural killer (NK) cell levels in NSCLC patients who underwent major lobectomy by VATS or thoracotomy.

METHODSTotally, 98 consecutive patients with stage I NSCLC were recruited and assigned into VATS or thoracotomy groups. Peripheral blood samples were taken on 1-day prior to operation, postoperative days (PODs) 1, 3, 7, 30, and 90. Circulating Treg and NK cell counts were assayed by flow cytometry, defined as CD4 + CD25 + CD127 low cells in CD4 + lymphocytes and CD56 + 16 + CD3- cells within CD45 + leukocytes respectively. With SPSS software version 21.0 (SPSS Inc., USA), differences between VATS and thoracotomy groups were determined by one-way analysis of variance (ANOVA), and differences between preoperative baseline and PODs in each group were evaluated by one-way ANOVA Dunnett t-test.

RESULTSIn both groups, postoperative Treg percentages were lower than preoperative status. No statistical difference was found between VATS and thoracotomy groups on PODs 1, 3, 7, and 30. On POD 90, Treg percentage in VATS group was significantly lower than in thoracotomy group (5.26 ± 2.75 vs. 6.99 ± 3.60, P = 0.012). However, a higher level of NK was found on all PODs except on POD 90 in VATS group, comparing to thoracotomy group.

CONCLUSIONSLower Treg level on POD 90 and higher NK levels on PODs 1, 3, 7, 30 in VATS group might imply better preserved cell-mediated immune function in NSCLC patients, than those in thoracotomy group.

Objective To compare the difference of cutpoint and clinical significance of HbA1C for the diagnosis of abnormal glucose metabolism in two population groups with different ages.Methods According to oral glucose tolerance test(OGTT),the cutpoint and clinical significance of HbA1C for the diagnosis of type 2 diabetes and impaired glucose regulation(IGR)were investigated in the two population groups.Results The mean HbA1C of 1 064 young subjects in an academy and 1 671 aged subjects in a community were 5.31% ±0.41% and 5.79% ±0.71%,respectively.The cutpoints of HbA1C for diagnosis of diabetes were 5.7%(specificity 86.7%,sensitivity 66.7%)and 5.9%(specificity 73.8%,sensitivity 80.1%)in the two population groups,and 5.6% for diagnosis of IGR (specificity 82.8%,sensitivity 55.8%)and 5.7%(specificity 60.9%,sensitivity 64.3%),respectively.87.8%,78.7%,and 38.5% were diagnosed diabetes by current OGTT criteria at HbA1C levels of ≥5.7%,≥5.9%,and≥6.5%,IGR being 61.6%,39.6%,and 4.1%,and normal glucose tolerance being 24.4%,10.0%,and 0.4%.Conclusion The cutpoints of HbA1C for diagnosis of diabetes and IGR are different in populations with different ages and HbA1C levels.As one of diagnostic criteria for diabetes,HbA1C 6.5% with relatively higher specificity and lower sensitivity must be combined with fasting blood glucose,random blood glucose,and OGTT.

OBJECTIVETo examine risk factors of chronic obstructive pulmonary disease (COPD) deaths in Chinese military elderly men.

METHODSA cohort analytic study was carried out in Xi'an, China. A total of 1268 retired military males aged 55 or older were examined in 1987 and followed for 18 years. Main outcome measures were all causes and COPD deaths.

RESULTSThe total person-years of follow-up from 1987 until June 2005 was 18 766.28. The mean follow-up time was 14.35 years; A total of 491 had died, with 748 alive and 29 lost of follow-up. COPD was the second cause of death in all deaths (16.90%). Results Univariate analysis of Cox model showed that age, number of smoking cigarettes per day, duration of smoking, negative affairs and existing COPD were risk factors of COPD deaths and the relative risks [95% confidence intervals (CI)] were 1.13 (1.09-1.17), 1.04 (1.02-1.06), 1.03 (1.01-1.04), 1.81 (2.85-6.77) and 4.39 (2.85-6.77) respectively. Data from Multivariate analysis of Cox model showed that age, number of smoking cigarettes per day and existing COPD were risk factors of COPD death with relative risks [95% confidence intervals (CI)] as 1.10 (1.06-1.15), 1.03 (1.01-1.06) and 3.07 (1.90-4.98) respectively. The risks for deaths increased significantly with increasing amount and duration of smoking resulting from all causes and COPD. Compared with current smokers, former smokers had lower risks of total mortality(excess risk reduction of 66.67%).

CONCLUSIONCOPD was the second cause among all deaths in this cohort. Age, number of smoking cigarettes per day and existing COPD were the risk factors of COPD deaths which called for further survey to examine the relationship between quitting smoking and COPD deaths in this cohort.

OBJECTIVETo explore the efficacy and safety of endoscopic submucosal enucleation (ESE) for gastric submucosal tumors (SMTs) originated from muscularis propria.

METHODSA total of 116 patients with gastric SMT originated from muscularis propria underwent ESE in Department of Gastroenterology of the Taizhou Hospital between July 2006 and March 2011. The occurrence of intra-operative and post-operative complications and corresponding treatment were recorded. After the treatment of ESE, the patients were followed up endoscopically.

RESULTSThe success rate of operation was 96.6%. The mean time of the procedure was (51.9±16.3) min. Complications included intra-operative bleeding (n=9, 7.8%), perforation (n=20, 17.2%), and post-operative bleeding (n=3, 2.6%). Among them, 5 cases (4.3%) required surgical intervention. None of patient had other complications such as peritoneal abscess or peritonitis. The mean hospitalization time after ESE was 6.1 days. The median follow-up period was 12 months (range, 3-48 months) and there was no residual tumor or recurrence.

CONCLUSIONESE is a safe and feasible treatment for patients with gastric SMT originated from muscularis propria.

OBJECTIVETo observe the clinical efficacy and benefit response of extracorporeal high frequency thermotherapy (EHFT) combined with Chinese medicine (CM) in the treatment of patients with advanced nonsmall cell lung cancer.

METHODSThe study adopted a prospective, small sample and randomized controlled method, and the advanced non-small cell lung cancer patients were assigned to two groups according to the table of random digits, one having the treatment of EHFT combined with CM (the treatment group), the other only with CM (the control group). The patients in the treatment group were treated with EHFT one hour once per day, together with CM differentiation decoction, 250 mL orally taken, twice daily for 14 days as one cycle, and 3-4 cycles was performed. The patients in the control group were treated only with CM differentiation decoction using the same dose as the treatment group. The efficacies were evaluated after three to four cycles of treatment. Primary endpoints were disease control rate (DCR) and time to progression (TTP). Secondary endpoints were overall survival time and 1-year survival rate.

RESULTSSixty-six patients accomplished the study. After the patients underwent different treatments, none of the patients got a complete response or partial response in both groups. In the treatment group, DCR was 72.2%, and 10 had progression of disease (28.8%), while the DCR of the control group was 63.3%, and 11 had progression of disease (36.7%); there was a significant statistical difference (P <0.05), suggesting that the combined regimen had superiority on the DCR. As for long-term efficacy, the median survival time (MST) of the treatment group was 7.5 months, TTP was 5.5 months, and 1-year survival rate was 21.4 %; in the control group, the results were 6.8 months, 4.5 months and 16.6% respectively. There was significant statistical difference on TTP (P <0.05), but no difference on MST or 1-year survival rate.

CONCLUSIONEHFT combined with CM differentiation has better tolerance and short-term efficacy in the treatment of patients with advanced NSCLC.

Objective To investigate the clinical features and differential diagnosis of lepromatous type brain abscess. Methods A total of 18 cases with brain abscess admitted to Department of Neurosurgery, Cancer Center, Sun Yat-sen University during October 2000 to February 2007 were retrospectively analyzed with regard to their clinical data and prognosis during follow-up.Results 11 cases had been diagnosed with gliomas and 7 cases had been diagnosed with metastatic tumors in other hospitals. Among the 18 cases, 16 patients took the onset in winter and spring. All of the 18 cases had not found the primary focus of infection. Two cases among them had got a fever 1 month prior to hospitalization. Among the 18 cases, 7 cases had higher total white blood cells (10.1×109/L-13.7×109/L), and 6 cases had higher neutrophil rate (80.8%-90.5%). And the other 11 cases had normal blood routine. After hospitalization, all of the patients received MRI. 14 cases of them were diagnosed with brain abscess, 2 cases with metastatic tumor, 1 case with glioma, and 1 case with parasite. All of the patients got bacterial culture, and showed asepsis in 9 cases, Gram-positive bacteria in 4 cases, streptococci in 3 cases,Staphylococcus epidermidis in 1 case, and Klebsiella pneumoniae in 1 case. Twelve cases underwent resection, and 6 cases received puncture and drainage. During the follow-up ranging 1-6 years, 17 cases healed well, and 1 case get better. Conclusion Lepromatous type brain abscess commonly occurs in winter and spring. The clinical manifestations are untypical. MRI is the most valuable auxiliary examination, and the magnetic resonance spectroscopy and diffusion weighted imaging takes an important role in differential diagnosis between brain abscess and cystic brain tumor with necroses.

Objective The objective of this research is to construct a clinic-usable genechip method for detection of hepatitis B virus lamivudine-resistant mutants and basal core promotor/Pre-C mutants, compare this method with DNA sequencing to investigate this genechip's character (semity, specificity, stability and practicability in clinic) and apply it in clinic. Methods This genechip detection method can detect the DNA and 8 mutative site of HBV, include 3 lamivudine-resistant mutation site (No. 180, 204, 207 site in DNA polymerase gene) ,5 HBeAg escape-related mutation site(nt 1896, 1899, 1862, 1764, 1762 site in BCP/Pre-C region).The results of genechip method was verified by DNA sequncing. Results In detecting HBV DNA, the results of genechip were agree with 100% of the results of DNA sequencing. In detecting HBV mutants, 251 sites (in 32 samples, 256 sites) showed the same results using both methods, and only 5 sites were not completely match(P >0.05). In these 5 sites, genechip methods got multi-infection results, but sequencing got single-infection results.Conclusion These results suggest that genechip method has the same positive rate and almost these same specificity with DNA sequencing method, and is better than DNA sequencing method in detecting multi-infected HBV strains.
