With references of historical materials and modern literature regarding acupoint characteristic, a secondary analysis on the concept, origin, related factors and research methods in present research of acupoint characteristic is performed. The acupoint characteristic should be considered as an acupoint inherent attribute that could explain physiological and pathological manifestations at the same time, including location attribute and function attribute, which is related with time and treatment method. Some re-thinking on acupoint characteristic is proposed as well as advice on further research method and direction, hoping to promote the research development of acupoint characteristic.

OBJECTIVETo develop a best chitosan film for using as a drug sustained-release system through the evaluation of the sustained-release property, degradation property, and cytotoxicity to osteoblast.

METHODSOrthogonal experiments were designed to determine the best combination of chitosan film preparations. Drug release rate was determined with Coomassie brilliant blue G250. In a separate study, chitosan films were placed into the test tubes with buffer solution and 10(7) U/L lysozyme. The degradation rate was calculated. Osteoblasts derived from fetal rat calvarial were cultured on chitosan films. Cell proliferation was tested by methyl thiazolyl tetrazolium (MTT) assay. The relative growth rate was calculated and the cytotoxicity was graded.

RESULTSThe best processing condition was 1% acetic acid, chitosan concentration of 2 mg/mL, 6% sodium tripolyphosphate (STPP) concentration, and cross-linking time of one hour. The resulting chitosan film released 33.13% of bovine serum albumin (BSA) within 8 d, 36.73% of BSA within four weeks and the cytotoxicity grade was 0 or 1.

CONCLUSIONThis chitosan film possesses good sustained release property, and a good degradation rate.

Chinese medicine (CM) is a discipline with its own distinct methodologies and philosophical principles. The main method of treatment in CM is to use herbal prescriptions. Typically, a number of herbs are combined to form a formula and different formulae are prescribed for different patients. Regularities in the mixture of herbs in the prescriptions are important for both clinical treatment and novel patent medicine development. In this study, we analyze CM formula data using latent tree (LT) models. Interesting regularities are discovered. Those regularities are of interest to students of CM as well as pharmaceutical companies that manufacture medicine using Chinese herbs.

In this paper, the five strains of Polygonatum odoratum were used as the experimental materials to test the supercooling point, freezing point, the degree of supercooling, the transition stage time, cooling time and water composition of the plant tissue. The cold resistance of P. odoratum was analyzed with the Gray Correlation Method. The results showed that the cold resistances of the five strains of P. odoratum were different, and the water content of plant tissue had some relevance with freezing point and supercooling point, whereas, it could not be measured when the moisture content was too low. The order of cold resistance of the five strains of P. odoratum was ZJCY, DYYZ, XYYZ, CYYZ and JZ I.

OBJECTIVETo compare the clinical effect of acupuncture treatment and western medicine Carbamazepine for thalamic pain.

METHODSCrossover trial design was used, 11 cases diagnosed as thalamic pain were randomly divided into two groups according to the mini-unbalance-index method, group I (with 6 cases received acupuncture first and then western medicine) and group II (with 5 cases received western medicine first and then acupuncture). When the effects were evaluated, the two groups were named as acupuncture group and western medicine group, 11 cases in each group. The method of clearing away the heart fire, regulating the spirit, activating blood and relieving pain was adopted in acupuncture treatment, Ximen (PC 4), Yinxi (HT 6), Xuehai (SP 10) and Zhaohai (KI 6) were selected; the western medicine group was treated with oral administration of Carbamazepine, and one course as well as the eluting period were both 10 days. The effects were evaluated with visual analogue scale (VAS) and evaluation scale of Anderson Cancer Center pain in US (MD Pain Evaluation value) respectively.

RESULTSThe VAS and MD value in two groups were obviously decreased after treatment (both P < 0.05), while there was no significant difference between two groups; the markedly effective rate of pain relieving in acupuncture group was 63.6% (7/11), which was higher than that of 36.4% (4/11) in western medicine group, but there was no significant difference between two groups.

CONCLUSIONAcupuncture treatment of regulating spirit, activating blood and relieving pain has a better therapeutic effect for thalamic pain, and can reach to the same therapeutic effect with western medicine Carbamazepine.

OBJECTIVETo establish two-dimensional electrophoresis profiles from human laryngeal squamous cell carcinoma tissue and paired normal tumor-adjacent mucosa epithelia tissue, and to identify differential expression proteins.

METHODSThe total proteins of human laryngeal squamous carcinoma tissue and paired normal tumor-adjacent mucosa epithelia tissue were separated by immobilized pH gradient-based two-dimensional gel electrophoresis (2-DE). The differential expression proteins were analyzed using image analysis software, then identified using mass spectrometry and database searching.

RESULTSWell-resolved, reproducible 2-DE patterns of laryngeal squamous cell carcinoma and adjacent normal mucosa epithelial were obtained. Differential protein spots were defined as spots in 2-DE gels. Thirteen proteins were preliminarily identified, naming which 10 proteins were upregulated in laryngeal cancer tissue. Such as cofilin-1, nuclear body protein SP140, GRP94, HSP 90, GSTP1-1, superoxide dismutase [Mn], cyclophilin A, proteasome activator complex subunit 2, apolipoprotein A-I precursor, CaM-like protein and so on. There were 3 proteins downregulated in laryngeal cancer tissue, which were fatty acid-binding protein, calgranulin A and calgranulin B.

CONCLUSIONSThirteen proteins which are associated with the tumorigenesis of the laryngeal squamous cell carcinoma were characterized. These extensive protein variations indicate that multiple protein molecules should be simultaneously targeted as an effective strategy to counter the disease. It is better for understanding of the oncogenesis and pathogenesis in a global way, which in turn is a basis-for the rational designs of diagnostic and therapeutic methods.

Objective: To observe the clinical efficacy of mind-refreshing and balance-restoring needling method combined with Frenkel exercises in treating ataxia after cerebral stroke. Methods: The recruited 120 patients were randomized into an observation group and a control group, with 60 cases in each group. The control group was intervened by mind-refreshing and balance-restoring needling method, while the observation group was given additional lower-limb Frenkel exercises. Before and after treatment and at the follow-up, the ataxic lower-limb function was scored using Berg balance scale (BBS) and international cooperative ataxia rating scale (ICARS), and Barthel index (BI) was adopted to score the activities of daily living (ADL). Results: After treatment, the markedly effective rate was 70.2％ and the total effective rate was 96.5％ in the observation group, versus 39.7％ and 87.9％ in the control group, and the differences in the markedly effective rate and the total effective rate were statistically significant (P<0.01, P<0.05). The intra-group comparisons showed that the BBS, ICARS and BI scores after treatment and at the follow-up were significantly different from those before treatment in both groups (all P<0.01).There were significant differences in the BBS score between the two groups after treatment and at the follow-up (P<0.05, P<0.01); the between-group differences in the ICARS and BI scores were statistically insignificant after treatment (both P>0.05), while the between-group differences in the ICARS and BI scores were statistically significant at the follow-up (both P<0.05). The interaction effects between the scoring time of BBS and BI and the group factor were statistically significant (P<0.01, P<0.05). Conclusion: Mind-refreshing and balance-restoring needling can effectively improve the lower-limb ataxic symptoms and ADL after stroke; when combined with Fenkel exercises, this needling method can produce more significant efficacy.
