OBJECTIVETo analyze the influence of intravesical Pirarubicin (THP) instillation on the prediction results of European Organization for Research and Treatment of Cancer (EORTC) risk tables and to discuss the efficacy of EORTC risk tables in clinical application.

METHODSWe retrospectively reviewed the clinical data of 389 patients with non-muscle invasive bladder cancer after TURBT treated with intravesical pirarubicin instillation. According to the EORTC Scoring System, all the cases were divided into low risk group, intermediate risk group and high risk group. The 1-year and 5-year recurrence and progression rates of each group were calculated and compared with the prediction results of the EORTC risk tables.

RESULTSThe 1-year recurrence and progression rates of the low risk group were 8.0% and 0, those of the intermediate risk group were 31.0% and 2.8%, and those of the high risk group were 52.5% and 18.6%, respectively. The 5-year recurrence and progression rates of low risk group were 16.0% and 5.3%, those of the intermediate risk group were 42.6% and 10.7%, and those of the high risk group were 63.9% and 41.9%, respectively. The prediction results of progression rate were similar to that of the EORTC risk tables while the overall recurrence rate was lower.

CONCLUSIONSThe EORTC risk tables can be effectively used to predict the recurrence rate and progression rate of non-muscle invasive bladder cancer. However, the EORTC risk tables have a tendency to overestimate the recurrence rate. Intravesical pirarubicin instillation is helpful to reduce the recurrence rate, yet has no obvious influence on the tumor progression.

Objective To analyze the clinical performance of free prostate-specific antigen (fPSA)detection by ECLIA method,and evaluate whether ECLIA is suitable for clinical use.Methods 341samples were collected and tested prostate-specific antibodies with CMIA and ECLIA methods.These samples contain:97 samples with abnormal high PSA value tested by CMIA method,and 244 normal PSA samples.Use CMIA as the reference method,and detect fPSA,tPSA levels,and the ratio of fPSA/tPSA.Analyze the testing results with statistical methods.Results Compared with CMIA,correlation coefficent of ECLIA fPSA detection is 0.99; correlation coefficent of f/tPSA ratio detection is 0.96; the sensitivity,specificity of ECLIA f/tPSA ratio detection are 85.71％,92.6％ respectively,the agreement rate with ECLIA is 87.4％.No cross reaction with bilirubin,lipohemia,hemolysis,RF,CEA,AFP,CA125,CA153,CA199 were found in the tests.Conclusion The ECLIA method for free prostate-specific antigen detection showed good clinical performance; and is suitable for clinical use.

OBJECTIVE: To investigate the optimal doses of X-ray irradiation and plasmid injection in the anti-tumor effect of the pcDNA3. 1-Egr. 1p-p16 gene combined with radiotherapy in vivo. METHODS: We observed the anti-tumor effect of the pcDNA3. 1-Egr. 1p-p16 gene combined with radiotherapy with different doses of X-ray irradiation (2, 10, 20 Gy) and plasmid injection (10, 20, 30 microg) in nude mice with JF-305 pancreatic carcinoma, and detected the expression of p16 in tumor by RT-PCR. RESULTS: The tumor growth rate of the nude mice irradiated locally with 20 Gy X-rays after the plasmid injection was significantly lower (P < 0.05 ) than that of the nude mice irradiated locally with 2 Gy or 10 Gy X-ray 3 days after the irradiation. The tumor growth rate of the nude mice injected locally with 20 microg or 30 microg plasmid was significantly lower (P <0.05 ) than that of the nude mice injected locally with 10 microg plasmid. Both pcDNA3. 1-Egr. 1p-p16 group and pcDNA3. 1-Egr. 1p-p16 +20 Gy group had p16 mRNA expression, but the mRNA level of pcDNA3. 1-Egr. 1p-p16 +20 Gy group was higher than that of pcD- NA3. 1-Egr. 1p-p16 group. CONCLUSION In the pcDNA3. 1-Egr. 1p-p16 gene combined with radiotherapy in vivo the optimal dose of X-ray irradiation was 20 Gy and the optimal dose of plasmid injection was 20 microg. The anti-tumor effect of pcDNA3. 1-Egr. 1p-p16 combined with radiotherapy is better than that of radiotherapy or gene therapy alone, which may be related with the enhanced p16 expression in tumor after the irradiation.

OBJECTIVETo investigate the common resource of Chinese herbal medicine in western of Luoding City, Guangdong Province, and propose pertinent suggestions concerning the exploitation,utilization and conservation of the medicinal resources.

METHODSWith plant taxonomy method, we selected the JiaYi town as the center for local common Chinese herbal medicine resources, ecological environment and non-governmental investigation of medicinal.

RESULTSThere were 123 species of medicinal plants in Jiayi Town, including pteridophyte 11 species, gymnosperm 5 species, dicotyledon 97 species,and monocotyledon 12 species.

CONCLUSIONThis region has an excellent ecological environment and forest plant communities preserved relatively intact suitable for the growth of Lingnan Chinese herbal medicine, as well as a profound cultural background of folk medicine. The resources should be actively protected for further rational development and utilization.

OBJECTIVETo establish a quantitative method for determination of synephrine and N-methyltyramine in Citri Reticulatae.

METHODSamples were extracted with 30% methanol. ODS column was used with methanol-water-sodium dodecyl sulfate (55:45:0.1) as mobile phase. Detection wavelength was 285 nm.

RESULTSynephrine and N-methyltyramine in sample solution were well separated. Linearity of synephrine was good (r = 0.9999) in range of 0.35-11.24 microg. The average recovery was 97.1%, and RSD of repeatability was 1.9%.

CONCLUSIONThis method can be used for quality control of Citri Reticulatae.

OBJECTIVETo explore the molecular mechanism of exocrine immune inflammatory injury of Sjögren's Syndrome and the intervention of Banxia Qinlian Decoction (BQD).

METHODSTotally 18 female NOD mice were randomly divided into the model group, the positive drug group, and the BQD group, 6 in each group. Six female BALB/c mice were recruited as a blank control group. Mice in the blank control group and the model group were gavaged with deionized water at the daily dose of 0.1 mL/10 g body weight. Tripterygium Tablet was administered by gastrogavage to mice in the positive group at the daily dose of 10 mg/kg. BQD was administered by gastrogavage to mice in the BQD group at the daily dose of 60 g crude drugs/kg. After 12 weeks of medication, mice were sacrificed. Their eyeballs were excised and blood collected. Tissues of bilateral parotids and submandibular glands were kept. mRNA transcriptional levels of IL-17, IL-6, type 3 muscarinic acetylcholine receptors (M3R), aquaporin protein-5 (AQP5) were detected by RT-PCR. Expression levels of M3R and AQP5 protein were detected by Western blot. Protein expression levels of IL-17 and IL-6 were detected by ELISA.

RESULTSCompared with the normal group, mRNA transcriptional levels and protein expression levels of IL-17, IL-6, M3R, and AQP5 were significantly up-regulated in the model group (P < 0.01). Compared with the model group, mRNA transcriptional levels and protein expression levels of IL-17, IL-6, M3R, and AQP5 were significantly down-regulated in the positive drug group and the BQD group with statistical difference (P < 0.01, P < 0.05). Compared with the BQD group, mRNA-transcriptional levels of IL-17, IL-6, and M3R, as well as M3R and AQP5 protein expression levels were significantly down-regulated in the positive drug group (all P < 0.01).

CONCLUSIONThe molecular mechanism of BQD in inhibiting SS exocrine neurotoxic injury might be possibly related to regulating Th17/IL-17 immune inflammatory way.

The main factors which affected the isolation, purification and cultivation of Pinellia cordata protoplasts from leaves were studied. The results indicated that the optimum enzyme solution for P. cordata leaves was 13% CPW + 1.0% Cellulose +0.1% Pectolase, at pH 6.0, temperature (25-28 degrees C ) for 4 h. The sucrose density gradient centrifugation was adopted to purificate the protoplasts collected, when 25% sucrose was used as mediator, centrifugating at 500 rpm for 10 min. When the protoplasts were shallow liquid and liquid-solid double layer cultured on the medium of MS + 0.5 mg x L(-1) 6-BA + 0.25 mg x L(-1) NAA + 13% mannitol at the density of 2.5 x 104 protoplasts/mL, or fed and nursed cultured at the density of 100-500 protoplasts/mL, cell division could be observed for 3 days; granular calli appeared for 30 days. Calli was proliferated on the medium of MS + 0.5 mg x L(-1) 6-BA + 0.25 mg x L(-1) NAA solidified by 0.55% agar, and differentiated and regenerated after 5-6 months. Plant generation of P. cordata is successfully established.
