In recent years, many versions of international standard terminologies on TCM have been established and enacted by different authoritative organizations worldwide. However, infantile tuina acupoints have never been included in them. The article illustrated the necessity of including infantile tuina acupoints in the international standard terminologies on TCM from the aspects of history, present state and specificity of these points. It also pointed out some problems of infantile tuina acupoints, such as different records of acupoints numbers, applications in the clinic and strategies applied in their English translation, and suggestions were provided accordingly, hoping that the infantile tuina acupoints can be included in the further revised versions of international standard terminologies on TCM.

Objective To explore the neuroprotective effect of ginsenoside Rg1 against PC12 cell apoptosis inducedby 1-methyl-4- phenylpyridinum (MPP+). Methods MPP+-induced apoptosis in PC12 cells, with the characteristics of dopaminergic neuron, were taken as the model of Parkinson disease in vitro. The cells were divided into control group, MPP+ group and 3 ginsenoside Rg1 pretreatment groups (concentrations 10, 20, and 50 μmol/L). MTT assay was used for detecting the cell viability, FCM for apoptosis ratio, TUNEL enzyme labelling for DNA fragment of the cell nuclear, and Western blotting analysis for cytochrome C protein. Results Ginsenoside Rg1 (10, 20, and 50 μmol/L) showed protective effect against MPP+-induced PC12 cells injury. Compared with MPP+-treated cells([52±4. 7]%), pretreatment with 10, 20, and 50 |imol/ L ginsenoside Rg1 increased the cell viability to (64 ± 3. 4) %, (72 ± 5. 2) % and (83±6.2)%, respectively (P<0. 05 or P< 0. 01). FCM analysis indicated that apoptosis rates decreased by ginsenoside Rg1 pretreatment, with the apoptosis rates in the control, MPP+ and 3 ginsenoside Rg1 groups (10, 20, 50 μmol/L) being 1. 8%, 44. 5%, 32. 9%, 21. 1% and 14. 2%, respectively. We also found that ginsenoside Rg1 pretreatment greatly decreased DNA fragment of PC12 cells. Western blotting analysis indicated that the cytochrome C was depressed by the ginsenoside Rg1 pretreatment. Conclusion Ginsenoside Rg1 can protect PC12 cells against MPP+-induced apoptosis in a concentration-dependent manner, which may be closely related to down-regulation of cytochrome C over-expression in the mitochondria.

Objective To explore the neuroprotective effect of ginsenoside Rg1 against PC12 cell apoptosis induced by 1-methyl-4-phenylpyridinum (MPP++). Methods MPP++-induced apoptosis in PC12 cells, with the characteristics of dopaminergic neuron, were taken as the model of Parkinson disease in vitro.

Objective To investigate the differential MSCT diagnostic features and comparative study of subtypes of renal cell carcinoma (RCC). Methods All of the renal cell carcinomas including 14 chromophobe RCCs (ChRCC), 10 papillary RCCs type 1(PRCC Ⅰ), 15 papillary RCCs type 2 (PRCC Ⅱ), 7 mucinous tubular and spindle cell carcinomas (MTSCCs) were investigated except for clear cell RCC. Dynamic contrast-enhanced CT was conducted in each case after intravenous administration of contrast agent, and the data including all the CT manifestations and the enhancement features were analyzed and contrasted together. Results The indexes including enhancement homogeneity, border of the tumor, renal pelvis violation, blood vessel in tumor showed statistically significant difference between the 4 subtypes (P<0.05), but no difference in the calcification of the tumor. Only the enhancement degree of MTSCC was lower than the kidney medulla in all of the three enhancement scanning phases, while the other 3 tumors' enhancement degree was higher than the kidney medulla in the cortical phase. Peak contrast enhancement of ChRCC was located in the cortical phase, however, peak contrast enhancement of the others did in the nephrographic phase. Conclusions Enhancement characteristics combined CT features is of great help in differential diagnosis of 4 subtypes of RCC.

BACKGROUND: Looking for effective measures to ensure the survival of the implanted stem cells against ischemia-induced hypoxia becomes the major concern in the research of cell transplantation therapy for cerebral infarction.OBJECTIVE: To study the effects of human Persephin gene transfer on hypoxia-induced apoptosis of neural stem cells.DESTGN: A randomized controlled basic study on cells.SETTTNG: Department of Neurology, the Second Affiliated Hospital of Sun Yat-sen University.MATERTALS: This study was completed in the Lin Baixing Laboratory Center of the Second Affiliated Hospital of Sun Yat-sen University from July to December in 2006. Recombinant adenovirus pAdCMV persephin was constructed in our lab. C17.2 neural stem cells were kindly provided by Prof. Snyder, Harvard Medical University, USA. Trypsin and DMEM/F12 were purchased from Gibco Company (USA), fetal bovine serum (FBS) from Sijiqing Biological Engineering Materials Co. Ltd (Hangzhou, China); Poly-lysine from Sigma Company (USA), TUNEL assay kit and FuGENE kit from Roche Molecular Biochemicals Company (Swiss), and S-P immunohistochemical detection kit and DAB reaction kit from Mycine Biological Engineering Company (Fujian). Rat anti-human monoclonal Nestin antibody and rabbit anti-human polyclonal persephin antibody were manufactured by Santa Cruz Company (USA), and persephin anti-senseoligodeoxynucleotide (ODN) was synthesized by Shanghai Biological Engineering Company.METHODS: ① Interventions: C17.2 neural stem cells cultured in vitro were infected by recombinant adenovirus containing persephin gene, and they were divided into four groups: blank control group (Group A, in which the C17.2 neural stem cells were not treated with hypoxia), hypoxic group [Group B, in which the cells were cultured at 37 ℃ in anaerobic incubation containing N2 (0.95 in volume fraction) and CO2 (0.05 in volume fraction)], hypoxia + pAdCMV persephin infection group [Group C, where the cells were cultured under the conditions as in group B after pAdCMV persephin infection for 48 hours], and hypoxia + pAdCMV persephin infection + anti-sense persephin ODN group (Group D, where the cells were infected by pAdCMV persephin and anti-sense persephin ODN. ② Evaluation: The expression of Persephin protein was analyzed using Western blotting; Apoptotic index was detected with terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick end-labeling (TUNEL) assay; The changes of apoptotic rate was determined with flow cytometry.MAIN OUTCOME MEASURES: Expression of Persephin protein; Apoptotic index; Apoptotic rate.RESULTS: ① Expression of Persephin protein: A specific band (relative molecular mass of 24 000) was detected by Western blotting in pAdCMV persephin infected cells, suggesting the successful expression of persephin gene.Interestingly, the cells infected with both pAdCMV persephin and anti-sense persephin ODN also showed the specific band of about 24 000, but with much less density, indicating that anti-sense persephin ODN could effectively inhibit the expression of pAdCMV persephin. However, this band was not presented in the blank control groups. ② Apoptotic index:The apoptotic index in group C was significantly lower than those in groups B and D (P＜0.01), but still higher than that of group A (P＜0.01), suggesting that persephin gene transfer could attenuate apoptosis to some extent. ③ Apoptotic rate: The apoptotic rate in groups B and D were obviously higher than that in group A (P ＜ 0.01), and it was lower in group C than in groups B and D (P＜0.01).CONCLUSION:Recombinant adenovirus can efficiently mediate Persephin gene transfer into C17.2 neural stem cells,resulting in high expression of the exogenous Persephin in vitro, which effectively reduces C17.2 neural stem cell apoptosis induced by hypoxia.
