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. 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 μmol/ 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).

Objective To compare the 96-week efficacy of de novo combination therapy with lamivudine ( LAM ) and adefovir dipivoxil (ADV) to that of optimization monotherapy for chronic hepatitis B (CHB).Methods A total of 155 CHB patients were collected from the First Affiliated Hospital of Anhui Medical University during 2007 and 2009.All patients were randomly assigned to LAM monotherapy group ( n =53 ),ADV monotherapy group ( n =50 ) or LAM with ADV combination group ( n =52 ) according to randomized digital table.The liver and kidney functions,HBV serum markers,and HBV DNA loads were tested every 24 weeks.If patients in LAM or ADV group had poor response or virological breakthrough,they were given optimized therapy with ADV or LAM at week 24,48 or 72.One-way ANOVA (normal distribution and homoscedasticity ) and non-parametric test (non-normal distribution ) were performed to compare measurement data among groups.The impact factors of early virological response were analyzed by binary Logistic regression method.Results At week 24,the complete virological responses in LAM group,ADV group,and LAM + ADV group were 66.0％ ( 35/53 ),34.0％ ( 17/50 ) and 90.4％ ( 47/52 ),respectively (x2 =35.282,P ＜ 0.01 ) ; while,at week 96 the complete virological responses in three groups were96.2％ (51/53),86.0％ (43/50) and 100.0％ (52/52),respectively (x2 =19.115,P＞0.05).At week 96,the cumulative recover rates of ALT in LAM group,ADV group,and LAM + ADV group were 86.8％ (46/53),82.0％ (41/50)and 94.2％ (49/52),respectively (x2 =3.613,P ＞0.05);however,the ALT levels in three groups were statistically different (x2 =11.195,P ＜ 0.01 ).At week 96,the HBeAg seroconversion rates in LAM group,ADV group,and LAM + ADV group were 31.3％ ( 10/32),20.7％ ( 6/29 ) and 38.7％ ( 12/31 ),respectively (x2 =2.313,P ＞ 0.05 ).Early virological response was not found in I patient in LAM group and 19 patients in ADV group; virological breakthrough occurred in 11 patients in LAM group and 1 patient in ADV group.All patients in LAM + ADV group had early virological responses and had no virological breakthrough.Logistic regression showed that complete virological response at week 24 was correlated with the baseline HBeAg,the initial treatment and HBV DNA load.Layered evaluation showed that there were significant differences in early complete virological responses among three groups for patients with positive HBeAg,HBV DNA ＞ 6.28 × 106 copies/mL and ALT ≤5 ×ULN (x2 =7.726,10.921 and6.100,P＜0.05 or ＜0.01) ; for those with HBV DNA ＞6.28 × 106copies/mL,complete virological response was not observed in ADV group treated for 24 weeks.Conclusion LAM combined with ADV has stronger antiviral activity,lower resistance rate and can improve liver function and virological response,especially for the patients with HBeAg-positive,high HBV DNA loads and ALT ≤5 × ULN.

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.

The therapeutic effects and mechanisms of traditional Chinese kidney-tonifying drugs in treating osteoporosis have become the focus under study. Pharmacological studies have shown that traditional Chinese kidney-tonifying drugs are promoters for the proliferation of osteoblasts, inhibitors for the activity of osteoclasts, regulators for the estrogen level and its receptor, plays important roles in promoting osteogenesis and suppressing adipogenesis of marrow mesenchymal stem cells (MSCs), modulating the function of OPG/RANK/RANKL system and the metabolism of calcium and phosphorus, as well as antioxidation. The anti-osteoporotic active ingredients and pharmacological action mechanism of traditional Chinese kidney-tonifying drugs are summarized from the perspective of molecular and cell biology in this paper, so as to provide references for the study of their mechanism of anti-osteoporosis and for the development of traditional Chinese kidney-tonifying and bone-strengthening drugs.

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.
