Literatures of study on acupoint functional effect of encephalic region with functional magnetic resonance imaging (fMRI) are collected from the database of China National Knowledge Information (CNKI) and Wan fang database. Analysis and comments are made respectively from the status quo of studies on combination of single acupoint, two acupoints and multiple acupoints under both physiological and pathological conditions. The results show that the corresponding encephalic regions can be specifically activated by acupuncture. And different regions can be activated by different acupoints. However, studies on single acupoint, two acupoints and three acupoints are the major researches carried out at present. It is still lack of observation on effect of commonly-used combinations in clinic. Moreover, the reliability of the research results are also affected by disunity of operations protocol, reinforcing or reducing manipulations, intensity or depth of stimulation and duration of needling retention. Therefore, it is necessary to establish a unified and standard operation protocol to strictly control the bias factors which may affect the result of research in the future, and take patients as the study target as much as possible, so as to further explore the central effect mechanism.

Objective To evaluate the performance of an improved skin prick test in the screening for allergens.Methods A total of 475 patients with chronic urticaria who aged from 3 to 81 years were enrolled in this study,and classified into the control group (n =235) and research group (n =240).Traditional and improved skin prick test were conducted in the control and research group respectively.The allergen detection rate was compared between the two test methods.Results The allergen detection rate was 65.4% and 67.2% respectively for the improved and traditional skin prick test,respectively (P > 0.05).House dust mites were the most common sensitizing agent.Conclusion The improved skin prick test can offer reliable evidence for chnical diagnosis with a relatively convenient and safe procedure.

BACKGROUND: Resistin has been shown to play an important role in the pathogenesis and progression of osteoarthritis. OBJECTIVE: To investigate the correlation between resistin level in serum and synovial fluid and the severity of knee osteoarthritis. METHODS: Seventy-four patients with knee osteoarthritis and 79 healthy individuals were recruited. The Noyes score method was used to assess articular cartilage damage arthroscopically. The severity of knee osteoarthritis was evaluated according to the Western Ontario McMaster University Osteoarthritis (WOMAC) score. The radiographic severity of knee osteoarthritis was assessed by the Kellgren-Lawrence (K-L) grading system. The levels of resistin and cross linked C-telopeptide of type Ⅱ collagen (CTX-Ⅱ) in serum and synovial fluid were determined by ELISA. RESULTS AND CONCLUSION: The resistin level in the synovial fluid was positively correlated with the radiographic severity of knee osteoarthritis, WOMAC pain, WOMAC function, and WOMAC total scores, but showed no correlation with the WOMAC stiffness score. There were no significant correlations between the serum level of resistin and WOMAC total scores, subscale or K-L Grading system in the the osteoarthritis patients. Multiple regression analysis showed that the correlation between the synovial fluid level of resistin and WOMAC scores was of significance after removal of other confounding factors, and the resistin level in the synovial fluid was positively correlated with Noyes scores and CTX-Ⅱ level. These results suggest that the resistin level in the synovial fluid can serve as a potential biomarker reflecting the severity of knee osteoarthritis and cartilage degenerative degree in patients with osteoarthritis.

Through scale-up cultivation of Eriobotrya japonica suspension cells using WAVE bioreactor, the cell growth and ursolic acid (UA) accumulation were studied. The comparison test was carried out in the flask and the reactor with cell dry weight (DW) and UA content as evaluation indexes. The culture medium, DW and UA content were compared in 1 L and 5 L working volumes of bioreactor. The orthogonal test with main actors of inoculation amount, speed and angle of rotation was developed to find the optimal combination, in 1 L working volume of bioreactor. DW of the cell growth and the UA content in bioreactor were higher than those of the shaker by 105.5% and 27.65% respectively. In bioreactor, the dynamic changes of elements in the fluid culture, the dry weight of the cell growth and the UA content in 1 L and 5 L working volumes were similar. Inoculation of 80 g, rotational speed of 26 r · min(-1), and angle of 6 ° was the optimal combination, and the cell biomass of 19.01 g · L(-1) and the UA content of 27.750 mg · g(-1) were achieved after 100 h cultivation in 1 L working volume of bioreactor. WAVE Bioreactor is more suitable than flasks for the E. japonica cell suspension culture, and culture parameters can be achieved from 1 L to 5 L amplification.

Objective To investigate the features of familiar facial palsy,ophthalmoplegia and dysphagia characterized by autosomal dominant inheritance in a family and to discuss the classification and pathogenesis of the disease.Methods Clinical,electrophysiological,pathological examinations were performed and blood samples were obtained from 5 patients and 26 family members.PCR protocol was used to identify a certain gene. Results In the 5 patients receiving physical examination,all had ptosis,external ophthalmoplegia,facial paralysis,dyphagia,hoarseness,decreased pharyngeal reflex;4 had amyotrophy of muscle of tongue,temporal nuscle,masseter and muscles of distal lower limbs;3 had proximal limb asthenia and distal limbs amyotrophy.Compared to those of oculopharyngeal muscular dystrophy(OPMD)with similar symptoms and signs,both electrophysiological manifestation and pathological findings of the family members supported the diagnosis of muscular dystrophy,but the(GCG)6(GCA)3GCG in the first exon of PABPN1 mutated neither in normal family members nor in patients.Conclusions This family presents clinical manifestations somewhat resembling to those of OPMD and distinctive to other disorders,but has a totally different genetic background from OPMD.It may be a new subtype of muscular dystrophy.
