Objective:The aim of this study was to investigate the distribution of carcinoembryonic antigen (CEA) in colorectal cancerous tissue and to evaluate its clinicobiological significance, especially its prognostic value. Methods: Distribution of tissue CEA in 189 patients with colorectal cancer were detected with immunohistochemical method, and its relationship with many clinicopathological parameters was analyzed with SPSS software. Results: CEA distributed in both tumor tissue and normal mucosa but there was a significant difference between them. Staining positive rate of CEA in tumor tissue was 96.3% , with 52.4% strong and 36.5% moderate. While in normal mucosa it was 17.4% , with 16.2% weak and 1.2% moderate. There was a close relationship between tissue CEA and many clinicopathological parameters, such as differentiation, invasion depth, metastasis to regional lymph node, preoperative serum CEA level, postoperative tumor recurrence, metastasis, and postoperative survive. Conclusions: CEA overexpression in colorectal cancer tissue. Tissue CEA is a good prognostic indicator for colorectal cancer reflecting its clinicobiological features. Combining tissue CEA with serum CEA level should be better for predicting prognosis,and patient with both elevated preoperative serum CEA level and strong expression of CEA in tumor tissue indicates the worst prognosis.

OBJECTIVETo discuss the anti-inflammatory mechanism of sinomenine on inflammatory media in joint of adjuvant arthritis rats.
METHODRats were randomly divided into the normal group and the model group, the prednisone group, the small, medium, large of sinomenine group (30, 60, 120 mg x kg(-1)). Except for the rats in the normal group, animals were modeled to adjuvant arthritiswith freund's complete adjuvant. The arthritis index (AI) and the swelling degree of paws were recorded, and the activity of IL-1, TNF and the levels of NO, PGE2 in joint fluids of secondary arthritis were determined.
RESULTCompared with the normal group, the activity of IL-1, TNF and the levels of NO, PGE2 in joint fluids of secondary arthritis were increased significantly in the model group (P < 0.05). Compared with the model group, it was shown to exert a dramatic inhibitory effect on secondary reaction of freund's adjuvant arthritis of rats, and the activity of IL-1, TNF and the levels of NO, PGE2 in joint fluids of secondary arthritis were significantly decreased in the sinomenine group (P < 0.05).
CONCLUSIONSinomenine has a remarkable treatment effect on RA. It is via NO to inhibit the activity of cytokines and decrease the level of inflammation mediators, which may be one of its curing RA mechanism.

Short tandem repeats (STRs) have been widely used in forensic sciences such as stain analysis and paternity testing. Although most of STR typing could give the reliable and clear results, some unusual typing have been observed in forensic practice. The anomalous typing could result from a lot of causes, including DNA genetic variation, poor quality or quantity of DNA template, different typing system or method, nonspecific reaction in PCR or anomalous electrophoresis migration. The unusual results may disturb the right interpretation of STR typing.

OBJECTIVETo explore the efficacy and determine the risk factors of survival for recurrent hepatocellular carcinoma(HCC) treated by percutaneous radiofrequency ablation (PRFA).
METHODSFrom January 1999 to December 2008, 82 patients with recurrent HCC, with the diameter less than 7 cm for solitary tumor, or the largest tumor less than 5 cm for multiple tumors(the number of tumors less than 3), were treated by PRFA. The significance of 12 clinical or pathological variables in the risk factors of overall survival were assessed.
RESULTSThe overall survival 1-, 3-, and 5-year survival rates were 75.8%, 43.9% and 34.5% (from the date of PRFA), and 95.1%, 63.2% and 46.6% (from initial hepatectomy), respectively. Univariate analysis indicated that tumor size before initial hepatectomy, recurrence interval from initial hepatectomy, number of recurrent tumors, diameter of largest recurrent tumor, serum glutamyl transpeptidase (GGT) and serum albumin (ALB) level were significant prognostic factors (P < 0.05, Kaplan-Meier Log-rank test). Multivariate analysis showed recurrence interval from initial hepatectomy, diameter of largest recurrence tumor, serum GGT and ALB level were significant prognostic (P < 0.05).
CONCLUSIONPRFA is effective for recurrent HCC. Recurrence interval from initial hepatectomy, diameter of largest recurrent tumor, serum GGT and ALB level are significant prognostic factors.

OBJECTIVETo assess the clinical effect and safety of the Chinese medicine Longbishu Capsule combined with mesylate doxazosin in the treatment of benign prostatic hyperplasia (BPH) of the kidney deficiency and blood stagnation type.
METHODSThis was a randomized, double-blind, double-simulation control study. We equally assigned 60 men diagnosed with BPH of the kidney deficiency and blood stagnation type to an experimental and a control group, the former treated with mesylate doxazosin plus Longbishu Capsule and the latter with mesylate doxazosin plus placebo. We compared the International Prostate Symptom Score (IPSS), quality of life (QOL), Chinese symptom score (CSS), maximal urinary flow rate (Qmax), and prostate volume between the two groups of patients before and after 6 months of medication.
RESULTSAfter treatment, there were 5 cured cases, 13 markedly effective cases, 9 effective cases, 1 ineffective case, and 2 eliminated cases in the experimental group, as compared with 2 cured cases, 8 markedly effective cases, 10 effective cases, 7 ineffective cases, and 3 eliminated cases in the control group. The total effectiveness rate was obviously higher in the former (96.4%) than in the latter (74.1%). IPSS, Qmax, and CSS were improved in both of the groups after medication, even more significantly in the experimental than in the control group (IPSS: 15.22 ± 2.98 vs 18.15 ± 5.88, P <0.05; Qmax: [13.56 ± 2.26] ml/s vs [11.78 ± 2.97] ml/s, P <0.05; CSS: 6.18 ± 2.13 vs 9.52 ± 3.15, P <0.05). Because of the difference in the QOL score between the two groups at the baseline (P = 0.038 <0.05), no more comparison was made in this aspect after treatment.
CONCLUSIONThe combination of Longbishu Capsule with mesylate doxazosin is safe and effective for the treatment of BPH.

OBJECTIVETo observe the effects of Qiangjing Tablets (QJT) on the semen quality and Fas/FasL signaling pathway in male SD rats with infertility.
METHODSModels of infertility were made in 50 male SD rats by intragastric administration of Tripterygium (GTW) for 3 weeks, and another 20 rats were taken as blank controls. Then 40 successfully established rat models were randomly divided into four groups, model control, low-dose QJT, medium-dose QJT, and high-dose QJT, the latter three groups treated intragastrically with QJT at 58 mg, 105 mg, and 233 mg per kg of the body weight per day, respectively. After 4 weeks of medication, the rats were killed for examination of semen quality and determination of the expression of the apoptosis factor FasL in the testis tissue.
RESULTSCompared with the blank controls, the model rats showed significant decreases in sperm concentration ([71.99 ± 9.72] vs [10.94 ± 3.58] x 10⁶/ml, P < 0.01), motility ([48.95 ± 4.10] vs [9.31 ± 5.79]%, P < 0.01), and viability ( [82.06 ± 6.16] vs [24.03 ± 6.93]%, P < 0.01). In comparison with the model controls, the rats in the QJT groups exhibited remarkably increased sperm concentration, motility, and viability, more significantly in the high-dose group ([59.66 ± 4.53] x 10⁶/ml, [35.45 ± 5.21] %, and [61.97 ± 9.75]%) and medium-dose group ([40.89 ± 4.90] x 10⁶/ml, [24.41 ± 4.79]%, and [60.06 ± 10.62]%) (P < 0.05 or P < 0.01). The expression of FasL was markedly reduced in the low-, medium-, and high-dose QJT groups (0.5215 ± 0.0189, 0.5371 ± 0.0364, and 0.4556 ± 0.0215) as compared with that of the model controls (0.5989 ± 0.0448 ) (P < 0.05 or P < 0.01).
CONCLUSIONBy upregulating the Fas/FasL signaling pathway, Tripterygium glycosides may induce the apoptosis of spermatogenic cells and reduce sperm concentration, motility and viability, resulting in infertility. The Chinese medicine Qiangjing Tablets can improve the reproductive function of male rats by decreasing the expression of the apoptosis factor FasL in the testis.

OBJECTIVETo investigate the correlation of International Prostate Symptom Score (IPSS) with the levels of interleukin-8 (IL-8) and cyclooxygenase-2 (COX-2) in the prostate tissue and expressed prostatic secretion (EPS) in patients with benign prostatic hyperplasia (BPH) complicated by prostatitis.
METHODSWe divided 80 BPH patients to be treated by transurethral resection of the prostate (TURP) into a simple BPH group (n = 30) and a BPH with prostatitis group (n = 50) based on the pathologic features. We statistically analyzed IPSS and the levels of IL-8 and COX-2 in EPS before surgery and the IL-8 and COX-2 levels in the prostate tissue after surgery.
RESULTSIPSS was positively correlated with the IL-8 and COX-2 levels in the prostate tissue and EPS of the BPH patients, moderately in the simple hyperplasia group (r > 0.5) and highly in the other (r > 0.8). The levels of IL-8 and COX-2 in the prostate tissue and EPS were significantly higher in the BPH with prostatitis group than in the simple BPH group (P < 0.05).
CONCLUSIONThe levels of IL-8 and COX-2 in EPS indirectly reflect those in the prostate tissue. IPSS and the levels of IL-8 and COX-2 in EPS can help determine whether BPH is complicated by histological prostatic inflammation.

Objective:The aim of this study was to improve the technique of percutaneous microwave coagulation therapy( PMCT) in the treatment of the patients with large liver cancers. Methods: The changes of temperature and coagulation area were measured in single and double irradiation for ex vivo liver tissue. Multiple irradiation schemes were devised by the aid of computer assistant design technique and verified by ex vivo experiment. Thermal monitor was conducted for 9 liver cancer cases with single irradiation and 4 cases with double irradiation. Multiple irradiation was applied for 16 liver cancer nodules ranging from 3 to 6 cm. Results: With 60 W× 300 seconds, single irradiation could create a coagulation area of 3.0 cm in transverse diameter. The suitable distance of double irradiation was 2.5 cm. Seven insertions could produce a spherical coagulation area of 7.1 cm in diameter. Incomplete necrosis only occurred in 2 treated nodules. Conclusion: PMCT can completely ablate liver cancers about 6 cm by suitably prolonging the irradiation duration and using rational multiple insertion schemes.
