ABSTRACT
Objective To observe the clinical efficacy of scalp cluster needling plus acupuncture at Conception Vessel points in treating generalized anxiety disorder.Method Sixty eligible subjects were divided into a treatment group and a control group by the random number table, 30 cases each. The treatment group was intervened by scalp cluster needling plus acupuncture at Conception Vessel points including Tiantu (CV22), Danzhong (CV17), Zhongwan (CV12) and Xiawan (CV10); in the control group, Shenmen (HT7), Daling (PC7), Neiguan (PC6), Qimen (LR14), Xinshu (BL15), Hegu (LI4) and Taichong (LR3) were selected. The treatments were given once a day, 6 sessions followed by 1-day interval as a treatment course, for successive 8 courses in total. The Hamilton Anxiety Scale (HAMA) scores of the two groups were compared before and after the treatment and in the follow-up study; the clinical efficacies were also compared.Result The treatment protocols in the two groups were both effective in treating generalized anxiety disorder, while the markedly effective rate was significantly higher in the treatment group than in the control group (P<0.05). The HAMA scores after treatment and in the 1-month follow-up study were significantly different from the score before the treatment in both groups (P<0.01). There were significant differences in comparing the HAMA score between the two groups respectively after treatment and in the 1-month follow-up study (P<0.05). Conclusion Scalp cluster needling plus acupuncture at Conception Vessel points shows significant advantage in treating generalized anxiety disorder compared to the ordinary acupuncture method.
ABSTRACT
Objective To observe the clinical efficacy of scalp cluster needling in treating essential tremor.Method Sixty patients with essential tremor were randomized into two groups, 30 cases each. The treatment group was intervened by scalp cluster needling plus acupuncture at the bilateral dancing tremor control zone; the control group was intervened by acupuncture at the dancing tremor control zone alone. The total effective rate and tremor score were observed after 30-day treatment, and the relapse rate was investigated 3 months after the intervention via telephone. Result The total effective rate was 96.7% in the treatment group, significantly higher than 73.3% in the control group (P<0.05); the tremor score of the treatment group was significantly lower than that of the control group at the end of the intervention (P<0.01); the 3-month telephone follow-up study showed that the relapse rate of the treatment group was significantly lower than that of the control group (P<0.05).Conclusion Scalp cluster needling plus acupuncture at bilateral dancing tremor control zone can produce a more notable efficacy in treating essential tremor compared to acupuncture at the dancing tremor control zone alone.
ABSTRACT
Objective@#To investigate the effect of polydimethylsiloxane (PDMS) matrix elasticity on osteogenic differentiation of rat marrow stromal cells (rBMSC).@*Methods@#A series of PDMS composite substrates with different elastic modulus were constructed by adjusting the relative concentrations of cross-linking agent. The Young's modulus was used to describe the elasticity of PDMS after measurement by atomic force microscope (AFM). After surface modification, rBMSC was seeded on PDMS matrix, and 7 days after rBMSC was cultured on the five different Young's moduli matrix, the differences of osteogenic differentiation of rBMSC were observed by the method of real-time PCR, Western blotting, and alkaline phosphatase assay.@*Results@#The PDMS was suitable for cell culture after surface modification, and by altering the concentration of cross-linking agent, PDMS could mimic the majority of the tissues' elasticity in vivo. The related osteogenic differentiation markers expression showed significant difference between the five matrixes (P<0.05), including type Ⅰ collagen (Col-Ⅰ), osteocalcin (OCN), osteopontin (OPN) and bone morphogenetic protein 2 (BMP2). The expression of osteogenic markers was up-regulated in the group that the Young's modulus was (354.1±40.9) kPa (P<0.05).@*Conclusions@#PDMS is a tunable elasticity matrix which could be used in the investigation of inducing rBMSCs into osteoblastic lineages. PDMS substrate stiffness has an obvious influence on rBMSC osteogenic differentiation.

ABSTRACT
<p><b>BACKGROUND</b>Vaccinium uliginosum L. is a type of blueberry found in the Chinese Changbai Mountains. We extracted Vaccinium uliginosum Anthocyanins (A(V.uli)) to investigate its bioactivity on suppressing cancer cells.</p><p><b>METHODS</b>A(V.uli) was extracted under different conditions of temperature (10°C - 35°C), pH 1.0 - 3.0, and diatomaceous earth (1.0 g - 3.0 g), followed by a HPLC analysis for the determination of the ingredients. Its anticancer bioactivities on human colon and colorectal cancer cells (DLD-1 and COLO205) were compared with those on Lonicera caerulea Anthocyanins (A(L.cae)) and Vaccinium myrtillus Anthocyanins (A(V.myr)), using cell viability assays, DNA electrophoresis and nuclear morphology assays.</p><p><b>RESULTS</b>The optimum process of A(V.uli) extraction involved conditions of temperature 20°C, pH 2.0, and diatomaceous earth 1.0 g/50 g of fruit weight. A(V.uli) contained 5 main components: delphinidin (40.70 ± 1.72)%, cyanidin (3.40 ± 0.68)%, petunidin (17.70 ± 0.54)%, peonidin (2.90 ± 0.63)% and malvidin (35.50 ± 1.11)%. The malvidin percentage was significantly higher (P < 0.05) than it in A(V.myr). A(V.uli) complied with a dose-dependent repression of cancer cell proliferation with an IC(50) (50% inhibitory concentration) value of 50 µg/ml, and showed greater anticancer efficiency than A(L.cae) and A(V.myr) under the same cell treatment conditions. These observations were further supported by the results of nuclear assays.</p><p><b>CONCLUSIONS</b>The extraction protocol and conditions we used were effective for anthocyanin extraction. A(V.uli) could be a feasible practical research tool and a promising therapeutic source to suppress human colon or colorectal cancers.</p>

<p><b>OBJECTIVE</b>To evaluate the validity and reliability of the Occupational Stress Scale (OSS) for Chinese offshore oil platform workers.</p><p><b>METHODS</b>A 51-item self-administered questionnaire developed in the light of Cooper's questionnaire and company's special situation was used to investigate 561 subjects.</p><p><b>RESULTS</b>51 occupational stress items relating to offshore oil production were subjected to factor analysis, and nine latent factors were identified, which explained 62.5% of the total variance. According to the contents described by the items included in each factor, they were respectively defined as: "the interface between job and family/social life (factor 1)", "career and achievement (factor 2)", "safety (factor 3)", "management problem and relationship with others at work (factor 4)", "physical factors of workplace (factor 5)", "platform living environment (factor 6)", "role in management (factor 7)", "ergonomics (factor 8)" and "organization structure (factor 9)". Significant difference in the score of five factors was observed among 12 different job categories by analysis of variance. After adjusting for potential confounding factors (age, educational level), hierarchical multiple regression analysis indicated that the score of the OSS was significantly and positively correlated with the poor mental health of the workers (P < 0.01). The consistent test between OSS and each factor showed that Cronbach's alpha were 0.72 - 0.91.</p><p><b>CONCLUSION</b>The OSS is a valid and reliable tool for measuring occupational stress, and can be used to explore occupational stress and its influence on health and safety problems in offshore oil workers.</p>
