Academic Journal of Second Military Medical University 2010;30(5):545-548
Objective:To summarize our experience on the diagnosis and surgical treatment of primary retroperitoneal tumor (PRPT). Methods: The clinical data of 315 patients with primary retroperitoneal tumor (from Jan. 2000 to Jun. 2008) were retrospectively analyzed,and the clinical experience on diagnosis and treatment was summarized. Results: The ratio of benign to malignant tumors in our group was 0. 55 : 1. Totally 294 patients received operation,including 161 cases of radical resection,69 cases of combined resection, and 64 partial palliative resection. Twenty-one patients received no operation. The prognoses of patients who received radical resection for malignant tumors were significantly improved compared with those of patients who received partial palliative resection (P<0. 05). Conclusion: Imaging diagnosis can effectively identify PRPT. Complete resection is the key for treatment of PRPT,and reoperation is an effective treatment for recurrent PRPT.

OBJECTIVETo compare plasma asymmetric dimethylarginine (ADMA), an endogenous nitric oxide synthase inhibitor, and cystatin C levels in patients with or without coronary artery disease (CAD).
METHODSWe recruited 87 CAD patients (39 with acute myocardial infarction and 48 with unstable angina pectoris) and 51 non-CAD controls. Plasma ADMA was measured by HPLC, cystatin C by particle-enhanced immunonephelometric assay (N Latex cystatin C, Dade Behring) with nephelometer (BNII, Dade Behring). CAD patients were further divided into low cystatin C group (< 1.0 mg/L, 36 cases) and high cystatin C group (> 1.0 mg/L, 51 cases).
RESULTS(1) The plasma levels of ADMA [(0.47 ± 0.15) µmol/L vs. (0.37 ± 0.15) µmol/L], SDMA [(0.39 ± 0.19) µmol/L vs. (0.28 ± 0.12) µmol/L] and cystatin C [(1.16 ± 0.32) mg/L vs. (0.73 ± 0.16) mg/L] were significantly higher in CAD patients than in controls (all P < 0.05). The plasma L-Arg was significantly lower in CAD patients than in controls [(59.4 ± 19.4) µmol/L vs. (83.7 ± 19.6) µmol/L, P < 0.05]. (2) Plasma ADMA was similar in CAD patients with low cystatin C level and controls [(0.42 ± 0.12) µmol/L vs. (0.39 ± 0.15) µmol/L, P = 0.251] and Plasma ADMA was significantly higher in CAD patients with high cystatin C level than in controls [(0.50 ± 0.17) µmol/L vs. (0.39 ± 0.15) µmol/L, P < 0.05].
CONCLUSIONADMA levels were significantly increased only in CAD patients with elevated cystatin C levels but not in CAD patients with normal renal function. The reported relationship between coronary heart disease and ADMA may not be direct, but could be secondary due to reduced renal function.

Objective To observe the clinical efficacy of acupuncture plus hyperbaric oxygen in treating depression after cerebral stroke.Method A total of 120 patients with depression after cerebral stroke were randomized into a treatment group of 60 cases and a control group of 60 cases. The treatment group was intervened by acupuncture plus hyperbaric oxygen, while the control group was intervened by Fluoxetine. Before the treatment, and respectively after 14-d and 28-d treatments, the patients were evaluated by Hamilton Depression Scale (HAMD) and National Institute of Health Stroke Scale (NIHSS), and the therapeutic efficacies were compared between the two groups. Result The treatment group was significantly superior to the control group in comparing therapeutic efficacy (P<0.01). After 1 course of treatment, the HAMD and NIHSS scores dropped significantly in the treatment group (P<0.01); the scores in the control group showed a declining tendency but without statistical significances (P>0.05). After 2 treatment courses, the HAMD and NIHSS scores were significantly different from those before the treatment in both groups (P<0.01), and the differences were more significant in the treatment group (P<0.01).Conclusion Acupuncture plus hyperbaric oxygen is effective in treating depression after cerebral stroke, and it can obviously improve the neural function.

Objective:
To investigate the potential value of 18F-fluorodeoxyglucose (FDG) PET/CT in predicting the survival of patients with primary tracheal malignant tumors.
Materials and Methods:
An analysis of FDG PET/CT findings in 37 primary tracheal malignant tumor patients with a median follow-up period of 43.2 months (range, 10.8–143.2 months) was performed. Cox proportional hazards regression analyses were used to assess the associations between quantitative 18F-FDG PET/CT parameters, other clinic-pathological factors, and overall survival (OS). A risk prognosis model was established according to the independent prognostic factors identified on multivariate analysis. A survival curve determined by the Kaplan-Meier method was used to assess whether the prognosis prediction model could effectively stratify patients with different risks factors.
Results:
The median survival time of the 37 patients with tracheal tumors was 38.0 months, with a 95% confidence interval of 10.8 to 65.2 months. The 3-year, 5-year and 10-year survival rate were 54.1%, 43.2%, and 16.2%, respectively. The metabolic tumor volume (MTV), total lesion glycolysis (TLG), maximum standardized uptake value, age, pathological type, extension categories, and lymph node stage were included in multivariate analyses. Multivariate analysis showed MTV (p = 0.011), TLG (p = 0.020), pathological type (p = 0.037), and extension categories (p = 0.038) were independent prognostic factors for OS. Additionally, assessment of the survival curve using the Kaplan-Meier method showed that our prognosis prediction model can effectively stratify patients with different risks factors (p < 0.001).
Conclusion
This study shows that 18F-FDG PET/CT can predict the survival of patients with primary tracheal malignant tumors. Patients with an MTV > 5.19, a TLG > 16.94 on PET/CT scans, squamous cell carcinoma, and non-E1 were more likely to have a reduced OS.

BACKGROUNDTo investigate the correlation of clinical features with pathology in chronic viral hepatitis (CH).
METHODSAnalyses of single factor and multiple factors of serum biochemical indices, imaging examination results, symptoms and signs with degree of pathological lesion of hepatic tissue in 973 cases of CH were conducted. Meanwhile, the hepatic functional index (AAPEA index) was used to investigate the role of serum biochemical indices in diagnosis of CH.
RESULTSIn these patients with CH,the severity of hepatic lesion was closely correlated to symptoms and signs, biochemical indices such as PTA, ALT, TBIL, ALB, A/G, gamma-globulin (gamma-G) by electrophoresis, AST and cholinesterase (CHE) as well as splenic thickness. AST was superior to ALT in reflecting degree of hepatic inflammatory activity. The total mistaken judgment rate of multiple factor analysis was 28.1%. The correlation coefficient of AAPEA index to degrees of hepatic inflammatory activity, fibrosis and pathological grading was 0.559, 0.545 and 0.529, respectively (P<0.000 1)
CONCLUSIONSThe biochemical indices such as PTA, ALT, TBIL, ALB, A/G, gammaG, AST, CHE and the determination of splenic thickness by ultrasonography B could reflect hepatic pathological changes to certain extent. AST was superior to ALT in reflecting degree of hepatic inflammatory activity. Incorrect judgment rate was high in determination of moderate and severe CH by multiple factor analysis. Conformity rate between AAPEA index and pathological diagnosis was better than any of them alone in diagnosing CH.

OBJECTIVETo study the effect of transfecting survivin antisense mRNA on growth and chemotherapy sensitivity of lymphoma cells.
METHODSEukaryotic expression plasmid pcDNA3. 1-antisense (As) survivin was constructed and transfected into Jurkat T lymphoblastic lymphoma cell lines with high expression survivin mRNA by use of lipofectmine gene transfer technique. Expression of survivin mRNA and protein were detected by reverse transcription-polymerase chain reaction (RT-PCR), immunohistochemical and Western blot. The effect of transfecting survivin antisense mRNA on the growth of Jurkat cell lines was monitored by population doubling time (PDT) and Apoptotic indexes (AI). The morphologic features were observed in transfected cells by light and electric microscopes. MTT assay was used to analyze the response of transfected cells to CTX and MTX.
RESULTSCompared with the control cells, the expression of survivin mRNA and protein were reduced after transfected pcDNA3. 1-Assurvivin 48 h, 5 w and 6 w, PDT (52 h) was prolonged. Apoptotic indexes were higher in transfected antisense survivin mRNA cells [20.2% (48 h)], 6.2% (5 w) and 6.8% (6 w) than control ones [2.1%, 1.3% (48 h)] and [1.3% (5 w) and 1.0% (6 w)]. The cells grow slowly and the dead cells increase and some swelling and apoptotic cells were observed in transfected pcDNA3. 1-Assurvivin groups by invert, light and electric microscopes. The Jurkat cell line of transfected pcDNA3. 1-Assurvivin had higher sensitivity to CTX and MTX. The rate of inhibition was higher in transfected group. There is a significant difference between the transfected group and untransfected one, P < 0.05.
CONCLUSIONSThe result indicated that survivin gene was very important for growth of Jurkat cells. To inhibit the expression of survivin will be significant in therapy of T lymphoblastic lymphoma. Survivin gene might be a target of therapy.

OBJECTIVETo evaluate visual inspection with Lugol's iodine (VILI) in cervical cancer screening program and to provide evidence for designing a cervical cancer screening algorithm in high risk areas of existing low-resource settings to reduce the incidence and mortality of cervical cancer.
METHODSWomen in Yangcheng county, Shanxi province were screened with VILI, colposcopy, liquid-based cytology test and human papilloma virus (HPV) DNA test. The efficacy of different screening tests was compared by Youden's index based on the pathology as the gold standard.
RESULTSIn the population being screened, the mean age was 40.80 +/- 10.75 years old. Based on pathological findings, 4.35% (32/735) of the subjects had >or= CIN (cervical intraepithelial neoplasia) II. The sensitivity and specificity for the VILI test (>or= positive) were 53.13 and 82.19, while 56.25 and 79.09 were for colposcopy (>or= low grade dysplasia) respectively. Comparing by the Youden's indexs, there was no statistically significant difference (P > 0.05) between VILI and colposcopy. However, statistical significant difference (P < 0.05) was found between VILI and liquid-based cytology test and HPV DNA test. In addition, there was no statistically significant difference (P > 0.05) found between the experienced doctors and the newly-trained doctors working in the field station.
CONCLUSIONWith low sensitivity when using microscope but low cost of equipments, VILI can be one of the primary screening tests in China's rural area with low-resource settings if the screening frequency is to be increased.
