Dendrobium huoshanense is a precious medicinal plant belonging to Dendrobium of Orchidaceae. It is a special medicinal material and extremely scarce in Huoshan county, Anhui province. At present, D. huoshanense has been greatly protected, which also makes it possible to industrialize relying on tissue culture and artificial cultivation technology. Three main planting methods were utilized for cultivating D. huoshanense including facility cultivation, under forest cultivation and simulative habitat cultivation. Firstly, the three cultivation modes and technical characteristics of D. huoshanense were compared and analyzed, and it was found that the ecological environment of D. huoshanense cultivated in the simulated environment was closer to that of wild D. huoshanense. Secondly, based on comparing the characters and quality of three cultivation modes, the results showed that the shape of D. huoshanense cultivated in simulated environment was more similar to that of "grasshopper thigh" recorded in Bencao Jing Jizhu, and its quality was better than that of facilities and under forest cultivation. The comprehensive benefit comparison of three modes showed that the simulated cultivation had high income, the lowest input-output ratio and significant economic benefit. The quality of cultivated D. huoshanense was further evaluated from four aspects of "excellent environment" "excellent shape" "high quality" "excellent effect", which summarized the comprehensive advantages of simulative habitat cultivation of D. huoshanense as follows: the original habitat and site environment of simulated wild D. huoshanense, the closer shape to the wild, the more content of main medicinal components, and higher economic benefit and better efficacy. The quality of D. huoshanense was improved by the use of simulative habitat cultivation, which has practical significance to guide its large-scale cultivation.

<p><b>OBJECTIVE</b>To assess the clinical efficacy of acupuncture at key acupoints combined with the routine rehabilitation training of limb function on spasmodic hemiplegia after cerebral infarction.</p><p><b>METHODS</b>Eighty-six cases were randomized into an acupuncture combined with rehabilitation group (group A, 44 cases) and a rehabilitation group (group B, 42 cases). In group A, the key acupoints were selected from head, face, chest, abdomen, shoulder, back, hands, feet and ankles such as Cuanzhu (BL 2), Danzhong (CV 17), Jianyu (LI 15) and Yanglao (SI 16) were stimulated with acupuncture. In combination, the routine limb rehabilitation training was applied, once every day. In group B, the routine limb rehabilitation training was applied alone. In both groups, 10 treatments made one session and 2 sessions were required totally. Before and after treatment, Fugl-Meyer scale and functional independent measurement (FIM) scale were adopted to assess the limb motor level and the activity of daily life in the patients respectively. The modified Ashworth scale was used to assess the effect of anti-spasm.</p><p><b>RESULTS</b>The total effective rate of anti-spasm was 90.9% (40/44) in the group A, which was superior to 73.8% (32/42) in the group B (P < 0.05). After 2 sessions of treatment, Fugl-Meyer score and FIM score were all improved in both groups (all P < 0.05) and the results in the group A were better than those in the group B (all P < 0.05). Additionally, the improvement of FIM score after the 1st session of treatment in the group A was better as compared with the group B, indicating the significant difference (P < 0.05).</p><p><b>CONCLUSION</b>Acupuncture at key acupoints combined with rehabilitation therapy effectively relieves the spasmodic condition of the patients with post-stroke spasmodic hemiplegia, improves the limb function and the life activity of the patients.</p>

<p><b>OBJECTIVE</b>To study the indoor environmental factors associated with the prevalence of asthma and related allergies among school children.</p><p><b>METHODS</b>A cluster sampling method was used and the ISAAC questionnaire was conducted. A total of 4612 elementary students under Grade Five of 7 schools were enrolled in the survey for the impact of indoor environmental factors on the prevalence of asthma and related allergies in several urban and suburban schools of Beijing.</p><p><b>RESULTS</b>A total of 4060 sample were finally analyzed including 1992 urban and 2068 suburban. The prevalence of wheeze, allergic rhinoconjunctivitis and atopic eczema in the past 12 months was 3.1% (61/1992), 5.3% (106/1992), 1.1% (22/1992) among urban children while 1.3% (27/2068), 3.1% (65/2068), 1.0% (22/2068) among suburban children respectively. The prevalence of wheeze and allergic rhinoconjunctivitis of the past 12 months in urban were both significantly higher than that in suburban (χ(2) = 14.77, 11.93, P < 0.01). The incidences of having asthma and eczema ever among urban children (5.3% (105/1992), 29.4% (586/1992)) were significantly (χ(2) = 39.03, 147.22, P < 0.01) higher than that among suburban (1.7% (35/2068), 13.8% (285/2068)). Although the distributions of indoor environmental factors were similar in both areas, passive smoking and interior decoration had different influence on the prevalence of asthma and related allergies among school children in the two areas. The significant impact of passive smoking on having asthma ever among suburban children was observed (OR = 2.70, 95%CI = 1.17 - 6.23) while no significant result in urban (OR = 1.06, 95%CI = 0.71 - 1.58); the percentage of interior decoration was 84.0% (1673/1992) among urban children and 80.0% (1655/2068) among suburban children, there was significant impact of interior decoration on the prevalence of having eczema ever among urban children (OR = 1.57, 95%CI = 1.17 - 2.10) but no significant results were found in suburban sample (OR = 1.06, 95%CI = 0.76 - 1.48).</p><p><b>CONCLUSION</b>The prevalence of asthma and related allergies among school children is much higher in urban areas than that in suburban areas and the indoor environmental factors such as passive smoking and interior decoration may differently explain the prevalence of asthma and related allergies in the two areas.</p>

<p><b>OBJECTIVE</b>To introduce a new technique using OsteoMed M3 titanium plate and screws for fixation of the posterior elements in the open position after expansive unilateral open-door laminoplasty and evaluate its clinical effect.</p><p><b>METHODS</b>Sixteen patients with multilevel cervical disc herniation and canal stenosis were treated with an expansive unilateral open-door laminoplasty using OsteoMed M3 plate and screws, and the follow-up period lasted for over 6 months.</p><p><b>RESULTS</b>Most of the patients had marked neurological improvement after the surgery. The mean Japanese Orthopaedic Association (JOA) score of the patients increased significantly from 9.06-/+2.380 (range 5 to 13) before surgery to 13.63-/+1.408 (range 11 to 16) at the final follow-up (P<0.005), with a mean recovery rate of 57.5%. One patient without postoperative neurological improvement underwent an additional anterior multilevel corpectomy. Bone fusion of the surgical lamina was achieved in all the cases without canal stenosis.</p><p><b>CONCLUSION</b>Unilateral open-door laminoplasty with OsteoMed M3 titanium plate and screw fixation can effectively maintain the expansion of the spinal canal and resist closure while preserving the spinal alignment and stability. This modified technique is easy to perform and is associated with a low complication rate.</p>
