To assay the quantity of the brucine ingredient in gastric content and hepatic tissues from the patient died of Semen Strychni hainanensi accumulative posioning.With standard brucine and the crude powder of the Semen Strychni hainanensi as control,the brucine ingredients in the above tissues were quantitatively scanned by the capillary elecrophoretic apparatus within the wave length ranging 190～600nm.The contents of the brucine ingredients in the gastric,hepatic tissues and the crude powder of the Semen Strychni sainanensi were 5 83mg/100ml,4 92mg/100g,and 3 07%(w/w)respectively.The high level of the brucine ingredients in the gastric content and the hepatic tissue is the cause of death.

Objective To evaluate pit pattern analysis for detection of early colorectal carcinoma and precancerous lesions. Methods A total of 162 lesions in 144 patients were examined with magnifying colonoscopy after staining, and their pit patter was analyzed with morphology and pathologic diagnosis. Results With confirmation of pathology, there were 34 non-neoplastic lesions and 128 neoplastic ones, in which 12 were carcinomas. The pit patterns in most non-neoplastic lesions (76. 5%, 26/34) were type Ⅰ or Ⅱ , and those in most neoplastic lesions (96. 1% , 123/128) was type Ⅲ, Ⅳ or Ⅴ. Pit patterns of cancerous lesions were mainly type Ⅴ (75.0%, 9/12), and those of 3 cases of advanced cancers were all type Ⅴ N. Conclusion Pit pattern classification is a very important tool to differentiate between neoplastic, nonneoplastic lesions and early cancer, which helps to decide later therapeutic intervention.

AIM: To establish HPLC fingerprint for the identification of Hydrocotyle sibthorpioides and its adulterants. METHODS: The chromatographic seperation was performed on a Diamonsil C_18(250 mm?4.6 mm,5 ?m)with a mobile phase consisting of acetonitrile-0.1% phosphoric acid,gradient eluent,at the flow rate of 1.0 mL/min.The UV detection was set at 340 nm. RESULTS: There was an apparent difference in fingerprint between Hydrocotyle sibthorpioides and its adulterants. CONCLUSION: The method is stable and reliable with a good reproducibility and provides a reference standard for identifying Hydrocotyle sibthorpioides and its adulterants.

Aim To investigate the change in neuropeptide Y(NPY) Y1 receptor level in infarcted myocardium tissues of (MI) rats. 　Method MI was induced by ligating the left descending anterior coronary artery (LAD) in the heart of rats. The techniques of reverse transcription polymerase chain reaction (RT-PCR) were used to identify the exist of NPY Y1 receptor mRNA in myocardial tissues. The technique of semi-quantitative PCR wa s used to observe the change of NPY Y1 receptor mRNA level. 　Results NPY Y1 receptor mRNA distributed in the heart tissues of rat. Compared with sham operated rats ,the NPY Y1 receptor mRNA level both in infarction area and non-infarction area was increased significantly after MI fo r 1d and 3d. The NPY Y1 receptor mRNA level in the heart tissues of sham-op erated rats was also significantly increased compared with that in control rats . 　Conclusion These results suggest that MI may result in increase NPY Y1 receptor level in the heart tissues of rats. Stre ss stimulation such as surgery may also increase the NPY Y1 receptor level in the heart.

AIM:To establish HPLC fingerprint for the root and rhizome of Clematis uncinata Champ and to compare the differences of clematis and Clematis uncinata in fingerprint. METHODS:Based on 10 batches of Clematis unciuata Champ,its chromatographic seperation was performed on Diamonsil C18 (250 mm ? 4. 6 mm,5 ?m)with a mobile phase consisting of acetonitrile -0.05% phosphoric acid,gradient eluent,at the flow rate of 0. 8 mL/min. The UV detection was set at 210 nm. RESULTS:The mutual mode to HPLC-UV fingerprints was set up,and the 23 mutual peaks were indicated. The similarities were compared among Cleuatis uncinata Champ and substitutes collected from different sources there were apparent difference in fingerprint. CONCLUSION:The method is stable and reliable with a good reproducibility and provides a reference standard for identifying medicinal clematis.

[ ABSTRACT] AIM:To investigate the changes of migration of lung adenocarcinoma cells promoted by IL-8 and the inner and outer mitochondrial membrane dynamic changes during this process.METHODS:Human lung adenocarci-noma cell line A549 was divided into control group and IL-8 group.Cell migration was analyzed by scratch detection and Transwell assay.The secretion of endogenous IL-8 was detected by ELISA.The protein levels of mitochondrial cytochrome C ( Cyt C) and mitochondrial outer membrane protein Tom20 was detected by Western blot.The mRNA expression of mito-chondrial fusion genes Mfn1, Mfn2 and OPA1 and fission genes Fis1, Drp1 and MTP18 was detected by RT-PCR.The morphological changes of mitochondria were observed by MitoTracker Red CMXRos dye staining and confocal microscopy. RESULTS:The migratory rate of A549 cells and endogenous secretion of IL-8 in A549 cells were higher than those in SPC-A-1 cells.The migratory rate of A549 cells was improved by IL-8 in a time-dependent manner.Compared with control group, the Tom20 protein expression was increased ( P<0.05 ) , and the Cyt C protein expression was decreased ( P<0.05).The expression of mitochondrial outer membrane fusion genes Mfn1 and Mfn2 was increased (P<0.05), and the expression of mitochondrial inner membrane fusion gene OPA1 was decreased (P<0.05).The expression of fission genes Drp1 and MTP18 were decreased (P<0.05), while the expression of Fis1 was no change (P>0.05).Under confocal microscope, the punctate aggregates in the mitochondria of the A549 cells treated with IL-8 were observed.CONCLU-SION:The migratory rate of A549 cells is increased by IL-8, which is related to the changes of mitochondrial fusion genes and the fission genes.

Objective To investigate application of femoston combined with Kuntai capsule in poor ovarian responders (PORs) receiving vitro fertilization. Methods 120 women with poor ovarian response after receiving IVF were s randomly elected. Pre-treatment with femoston plus Kuntai capsule was used for three menstrual cycles before the next cycle of assisted reproductive treatment. FSH, LH, E2, AMH, number of antral follicles, PSV, days of Gn, ampoules of Gn, cycle cancellation rate, E2 value of the day of HCG, follicle of less than 16mm, number of oocytes, fertilization rate, and number of good quality embryos were compared before and after treatment used. Results After pre-treatment, levels of FSH and LH were decreased, AMH, PSV were increased, E2 value of the day of HCG, number of antral follicles, follicle of less than 16 mm, oocytes, fertilization rate, and good quality embryos were increased; cycle cancellation rate was decreased, with significant differences (P< 0.05). Conclusions Femoston combined with kuntai capsule can effectively increase the functional reserve of the ovarian in poor ovarian responders, and can improve the outcome of IVF.

Objective To investigate the status about non-motor symptoms (NMS) in Parkinson's disease (PD) patients and the effect on quality of life. Methods 50 PD patients and 50 normal controls were investigated with the NMS questionnaire and the Healthy Survey short form (SF-36), and analysed with Spearman correlation. Results 98% of PD patients presented NMS, and recent memory loss, restless legs,constipation were the most frequent. All the NMS were more frequent than in the controls (P<0.05) except sexual desire, sexual difficulties and nausea or vomiting. All the dimensions of SF-36 were significantly different between the groups (P<0.05). The symptoms of constipation,decline in recent memory, decreased attention, restless legs and sleep disorders correlated with the scores of SF-36 (P<0.05). Conclusion NMS is common in PD patients, and impacts their quality of life.

AIM: To detect the expression level of telomere regulating factor tankyrase and its clinical significance in the origin and development of gastric adenocarcinoma. METHODS: Quantitative Real-time PCR was used to measure the expression of tankyrase mRNA in cancerous and normal adjacent tissues from 16 patients with gastric adenocarcinoma. Immunohistochemistry was used to detect tankyrase protein expressions in 37 gastric adenocarcinoma samples and 13 normal controls. RESULTS: The expression of tankyrase mRNA in gastric adenocarcinoma [median 1.44?10~ -2, range (3.88?10~ -5)-0.4847] was significantly higher than that in normal adjacent mucosa [median 1.0134?10~ -2, range 0-(4.933?10~ -2)] (P
