Objective To investigate the expression of peroxiredoxin 1 (Prx 1) in hepatocellular carcinoma (HCC) with portal vein tumor thrombosis (PVTT) and to evaluate the relationship between the expressions of Prx 1 and the postoperative recurrence of this disease. Methods Immunohisto chemistry and Western blotting were performed to examine the expression of Prx 1 protein in 40 patients with HCC with PVTT. Experiments on Sprague Dawley (SD) rat hepatoma model were further carried out to observe the pathological changes of Prx 1 by immunohistochemistry. Clinical outcomes were analyzed to find a correlation between the recurrence and positive rate of Prx 1. Results The expression level of Prx 1 was significantly up-regulated in primary tumor tissues than in tumor thrombosis samples (P<0.01). Immunohistochemistry results showed that the positive rate of Prx 1 in primary tumor tissues were higher than that in tumor thrombosis. Western blotting confirmed a same trend in the level of Prx 1, the average luminosity of the blots were 1534.2 and 735.6, respectively. There was a significant difference in SD rat hepatoma model, the 4, 8, 12, 16, 20 and 24-week positive rates of Prx 1 in liver tumor tissues were 60%, 80%, 75% ,65%, 40% and 25% respectively. Clinical outcomes showed that the time to first postoperative recurrence of Prx 1 in the primary tumor positive group was significantly higher than that in the negative group (6. 3 vs 3. 7 months, P<0. 01). Conclusions Prx 1 protein was down-regulated in HCC with PVTT. There was a negative correlation between the expression of Prx 1 and recurrence.

Objective This study is to analyse the clinical feature and risk factors of morbidity after pulmonary resection for lung cancer in patients older than 70 years. Methods The clinical records of 222 patients older than 70 years who had undergone pulmonary resection for their lung cancer was reviewed. The patients were divided into 3 groups: group Ⅰ including the patients who had severe postoperative complications, group Ⅱ including the patients who had mild complications and group Ⅲ including the patients who had no complications. Moreover, the definitions were made that group A1 = group Ⅰ+ Ⅱ , group B1 = group Ⅲ, group A2 = group Ⅰ and group B2 = group Ⅱ + Ⅲ. Univariate analyses and multivariate binary logistic regressions relating postoperative morbidity to risk factors were performed between the group Al and Bl, A2 and B2, resulting in the identification of the independent risk factors for overall morbidity and major morbidity. Results Preoperative comorbidity was recorded in 161 patients (72.5%). Lobectomy (64.9% ) was the predominant surgical procedure. The median number of dissected LN was 14, with the range of 0 to 57. The overall morbidity was 63.5% , including major morbidity of 13.5%. Perioperative mortality was 1.8% (4 cases). The results of binary logistic regression analyses indicated that the independent risk factors for overall morbidity were preoperative weight loss (P =0.020), ASA score (P<0.001), MVV (% predicted) (P=0. 020 ) and the number of dissected LN ( P = 0.004 ). The independent risk factors for major morbidity were ASA score ( P =0.003), MVV (% predicted) (P= 0.018) and the location of tumor (P=0.007). Conclusion Preoperative weight loss and numbers of dissected mediastinal lymph nodes were risk factor for lung cancer patients older than 70 years, Proper perioperative management for the elderly patients with high ASA score, low MVV (% predicted) or central tumor, could reduce the major postoperative morbidity.

To study the protective effect of astragalus saponin extracts (AS) on kidneys of diabetic rats. Totally 32 diabetic rats induced by streptozotocin (STZ) were divided into AS high and low dose groups, the positive control group and the model group (DM group) and orally administered with 50 mg x- kg(-1) x d(-1) AS 200, 25 mg x kg(-1) x d(-1) valsartan, 10 mL x kg(-1) x d(1) physiological saline, respectively. Another 8 healthy rats were collected in the normal control group (NC group, physiological saline 10 mL x kg(-1). d(-1)). All rats were treated for consecutively 6 weeks. After the administration, the body weight was measured every week, the concentration of blood glucose was monitored on week 2, 4 and 6. The total urine and total urinary protein (U-TP) in 24 h were measured by the metabolic cage method on week 6; At the end of week 6, blood samples were collected from hearts to detect blood urea nitrogen (BUN), serum creatinine (Scr), uric acid (UA) , total cholesterol (CH) triglyceride (TG) by biochemical methods. Kidneys were collect to calculate the kidney hypertrophy index and observe the pathological sections. The laboratory results show that in the DM group, the blood glucose, metabolic cost in 24 h, kidney hypertrophy index, U-TP, BUN, Scr, UA, TG were significantly higher than that in the NC group (P < 0.01, P < 0.05) , with significant pathological changes; After the intervention with AS, the metabolic value in 24 h, kidney hypertrophy index, U-TP, BUN, Scr, UA, TG were significantly lower in the high dose group (P < 0.01, P < 0.05), and the kidney hypertrophy index, BUN, Scr, UA, TG in the low dose group were also significantly lower (P < 0.05), with slight reduction in renal pathological changes in both groups. In conclusion, Astragalus saponin extracts have a certain protective effect on kidneys of diabetic rats.

OBJECTIVETo establish and optimize methods to detect the immune complexes (IC) of hepatitis B virus directly.
METHODSA C1q solid phase ELISA, mouse anti-HBs MAb solid phase ELISA and the complement consumption assay were established to detect the IC and these methods were optimized.
RESULTSAll the three methods were highly sensitive, specific and reproducible. The C1q used for coating tended to lose its activity easily at room temperature. Although strict requirements are needed for the raw and processed materials for complement consumption assay and the process of manipulation is complex, it can quantitatively detect IC. Comparing to the C1q solid ELISA and complement consumption assay, the mouse anti-HBs MAb solid phase ELISA has its own merits: convenience and stability.
CONCLUSIONMouse anti-HBs MAb solid phase ELISA is the best way to detect IC directly.

Objective To construct the eukaryotic expression plasmid containing glyceraldehydes-3-phosphate dehydrogenase (GAPDH) and cysteine protease inhibitor ( CPI ) gene from periodic Brugia malayi (Bm) and to lay foundation for studying multivalent vaccines. Methods Total RNA was extracted from periodic Bin. The BmGAPDH and BmCPI genes were amplified by RT-PCR. The PCR product was cloned and then subeloned into eukaryotic recombinant plasmid vector pcDNA3.1 (+). pcDNA3.1 (+)/BmGAPDH/BmCPI was constructed. The recombinant plasmids were screened and identified by digestion with restriction enzyme and PCR amplification, and were transformed into HeLa cell subsequently. The transient expression of BmGAPDH and BmCPI were examined by RT-PCR. The expressed protein was identified by sodium dodeeylsulphate-polyacrylamide gel electrophoresis(SDS-PAGE). Results Two specific bands of around 877 bp of BmGAPDH and 621 bp of BmCPI were amplified, consistent with the expected value. The same bands were obtained by double restriction enzyme digestion of recombinant plasmids or PCR using recombinant plasmid as template. BmGAPDH and BmCPI mRNA were highly expressed in transfeeted HeLa cell. The relative molecular mass (Mr) of the recombinant protein was about 54 × 103. Conclusion The recombinant eukaryotic expression plasmid pcDNA3.1 (+)/BmGAPDH/BmCPI has been constructed successfully and the protein is expressed correctly in mammalian cell.

PURPOSE: Triple-negative breast carcinoma (TNBC) is accompanied with high risk of metastasis and recurrence. The present study aimed to explore the clinicopathological and prognostic roles of putative tumor-related genes in patients with TNBC. METHODS: Thirty pairs of frozen-thawed tumors were used to select reliable indicators via real-time quantitative polymerase chain reaction (RT-qPCR). Then, 150 pathology specimens were used to evaluate the expression of proteins in TNBC through immunohistochemistry. In addition, Kaplan-Meier curves and Cox regression analysis were also performed to analyze the overall survival and disease-free survival. RESULTS: RT-qPCR results indicated that among all the proteins analyzed using fresh-frozen TNBC samples, the expression levels of only Survivin and zinc finger of the cerebellum 1 (ZIC1) were obviously different from those in the corresponding normal tissues. Survivin and ZIC1 expression had opposite effects on the clinicopathological diagnosis and prognostic assessment in TNBC patients. Further, there was a negative correlation between Survivin and ZIC1 expression. In addition, the “Survivin-positive ZIC1-negative group” was associated with histologic grade, lymph node metastasis, and TNM staging (p < 0.001) and this was also an independent factor for evaluating the prognosis of TNBC in patients. CONCLUSION: In summary, the expression levels of Survivin and ZIC1 in TNBC are different from those in normal tissues and are negatively correlated mutually. The combined detection of Survivin and ZIC1 expression levels could allow better comprehensive diagnosis and prognostic evaluation for TNBC patients.
