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 a new method of synthesis of resveratrol oligmer induced by photosensitizers, further analyze its free radical scavenging activity and analgesic activity. [Method] Resveratrol was dispersed in pH 7.4 phosphate buffer solution, mixed with pheophorbide, then illuminated by laser at 630nm. The oligmers in the filtrate were analyzed by HPLC-MS and isolated by preparative liquid chromatography. Free radical scavenging activity was determined by DPPH and ABTS method, and the analgesic effect was measured by hot plate test and acetic acid writhing test in mice. [Result] A new peak occurred and reached stable in reactive solution after 20 min illumination. It was identified as the dimer of resveratrol with conversion of 35%. Its concentrations on inhibition of 50% DPPH and ABTS radical were respectively 230 μg·mL-1 and 273 μg·mL-1. It reached maximum pain threshold at 180 min, and the inhibition rate of writhing number was 62.6% with better effects than resveratrol. [Conclusion] Reseratrol can be polymerized to the dimer after pheophorbide excited by red light, the resveratrol and its dimer both have the ability of eliminating free radicals and analgesic effects, but the dimer has the stronger activity.

Teaching of clinical skills is an important bridging phase from preclinical medicine to clinical practice.It is also an important element of medical students'clinical skills training.According to the character of internal medical cardiology,we should enhance the training of their clinical thinking ability,medical communication competence,and clinical operating ability to get satisfactory teaching effect.

p38 signaling pathway is an important branch of mitogen-activated protein kinase（MAPK)-mediated signal transduction pathway. It plays pivotal roles in various physiological and pathological events, such as inflammation, cell stress, apoptosis, cell cycle and growth. Previous research in osteoarthritis, p38 participation was found in the inflammatory factors activate, cartilage cell apoptosis etc. Disc degeneration, also associated with inflammatory response, apoptosis and pathological changes which p38 MAPK signaling pathways role is not clear. Some reports about this area are reviewed in this article.

Objective:To optimize the extraction conditions of gallic acid inWudang pineneedle tea and establish the assay meth-od. Methods:The content of gallic acid was determined by RP-HPLC-DAD. Orthogonal test was used to optimize the extraction condi-tions of gallic acid in Wudang pineneedle tea on the base of single factor tests. The optimal extraction conditions were as follows:adding 50-fold amount of water, and ultrasonic extracting for 60 min under 200W ultrasound power. Results:The linear range of gallic acid was 5. 10-51. 00 mg ·L-1(r=0. 9993), and the average recovery was 98. 7% (RSD=1. 93%, n=6). The average content of gallic acid in the samples was 0. 35 mg·g-1 . Conclusion: The optimal extraction conditions are simple and feasible, and the assay method is stable and reliable, which can be used for the extraction and content determination of gallic acid in Wudang pineneedle tea.

OBJECTIVE To analyze the profile of the pathogens and their drug resistance isolated from children with lower respiratory tract infection in Wenzhou area from Jan 2004 to Dec 2006.METHODS Lower respiratory tract secretions were obtained from children with lower respiratory tract infection for bacterial culture.The K-B method was applied for the antibiotic susceptibility test.RESULTS Total 1605 strains were isolated.The isolating rates of Gram-positive cocci,Gram-negative bacilli and fungi were 24.9%,61.2% and 14.0%,respectively.60.5%,and 54.6% of the isolates of Escherichia coli and Klebsiella pneumoniae produced extended-spectrum beta-lactamases(ESBLs).The rate of Penicillin-resistant Streptococcus pnenmoniae(PRSPN)was 30.6%.20.5% isolates of Staphylococcus aureus were MRSA.All isolates of Enterobacteriaceae and Gram-positive cocci were susceptible to imipenem and vancomycin in vitro.CONCLUSIONS Gram-negative bacilli are still the primary pathogens resulting in lower respiratory tract infection in children.Fungi and muti-drug-resistant bacteria are on the rise trend.

Objective To investigate endplate shape in low lumbar spine in patients with herniated nucleus pulposus, and analyze the relationshipbetween endplate shape and herniation of intervertebral disc, Modic changes. Methods The preoperative MRI of 110 patients wasreviewed. The endplate shape was divided into 3 types. Disc degeneration was classified with the Pfirrmann's way. Results Concave typewas the most common in the lower lumbar spine. Flat was more prevalent in lower than in upper. The L5~S1 segment was flat in most cases.Irregular type was the least and mainly appeared at the L5~S1 segment. Disc degeneration worsened from concave, flat, to irregular. Herniatedintervertebral disc dominated with flat and irregular endplates, and no-herniated ones dominated with concave. Modic changes more associatedwith irregular endplates. Conclusion Endplate shape may respond to the disc degeneration. Modic changes associate with irregularendplate.

OBJECTIVEThis study aims to observe and compare the influences of the casting alloy post and cores on magnetic resonance imaging (MRI).

METHODSSix casting alloy post and sores were fabricated for the experimental groups, and zirconia post and core served as the control. The seven types of post and cores were of the same size and shape. Each post and core was orally fastened to a volunteer and then imaged with sequences of T1-weighted spin echo imaging (SE-T1WI), T2-weighted turbo spin-echo imaging (TSE-T2WI), and diffusion weighted imaging (DWI).

RESULTSCobalt chromium alloy post and core generated severe artifacts, whereas gold palladium alloy post and core generated no obvious artifacts, and no difference was observed between the zirconia and the gold palladium alloy post and cores (P > 0.05). The pure titanium alloy post and core produced mild artifacts. The post and cores of the titanium, nickel-cadmium, and gold platinum alloys generated moderate artifacts with no significant differences (P > 0.05).

CONCLUSIONDifferent metal post and cores have different influences on MRI. With the exception of that generated by cobalt chromium alloy, the artifact generated by the single-alloy post and core does not influence the image of the normal head and neck.

Objective To explore the correlation of anxiety and depression with social support among caregivers of children with mental retardation and major related influencing factors.Methods 64 mothers of children with mental retardation were investigated by using the questionnaires of SAS,SDS and SSRS.The results underwent analysis.Results The incidence of anxiety among mothers of children with mental retardation was 23.4％,the incidence of depression was 40.7％.Mothers had higher scores of SAS and SDS than the national norm.The total score of social support was(32.19±5.02),which was lower than the national norm.The anxiety and depression was negatively correlated with social support.The influencing factors of anxiety and depression of mothers were family income.Conclusions The anxiety and depression among mothers of children with mental retardation was evident,the social supports for those mothers were insufficient.Effective social support was propitious to abate the anxiety and depression and promote quality of life of those children with mental retardation and their mothers.
