Objective To observe the clinical effects of simple obesity treated with needling and quick cupping therapy at the selected eight points around umbilicus. Methods Ninety-five cases were randomly allocated into an observation group and a control group. In observation group (n=50) patients were treated with acupuncture and quick cupping therapy at the selected eight points around umbilicus, namely Huaroumen (滑肉门 ST 24), Tianshu (天枢 ST 25),Wailing (外陵 ST 26),Shuifen (水分 CV 9), and Yinjiao(阴交 CV 7).In control group (n=45) patients were advised to take Sibutramine, an oral administration to suppress appetite. Relevant data concerning one's weight, body mass index (BMI), waist hip ratio (WHR) and distribution rate of body fat (F%) before treatment and after eight weeks' of treatment were collected to observe the effects. Results The total effective rate was 98.0%(49/50) in the observation group and 97.8%(44/45) in the control group. There was no significant difference on body weight and BMI between the two groups (P〉0.05), however the therapeutic effects on WHR and F% in the observation group were more satisfactory than those of the control group (P〈0.05). Conclusion Acupuncture and quick cupping therapy at the selected eight points around umbilicus have a good therapeutic effect on simple obesity, moreover acupuncture and quick cupping therapy can greatly improve the condition of WHR and F% for obesity patients, which is also safe and without any side effect. 展开更多

A 2-year-old pine plantation was selected to receive treatments of fertilizers and herbicides to evaluate effects on Nantucket pine tip moth infestations and the tree growth parameters of height, diameter and volume increment. Nitrogen and phosphorus fertilizers, and hexazinone and sulfometuron methyl herbicides were used in creating six treatments: (i) control; (ii) phosphorus; (iii) nitrogen and phosphorus; (iv) phosphorus and herbicide; (v) nitrogen, phosphorus and herbicide; and (vi) herbicide. Treatments were applied in 1987 and 1988. In 1987, trees treated with nitrogen, phosphorus and herbicide had significantly greater height, diameter and volume growth than trees not receiving fertilizer treatments, but did not have significantly higher tip moth infestations than control trees. Treatments receiving phosphorus only had much lower tip moth infestation rates than other treatments except nitrogen and phosphorus. In 1988, tip moth infestations were uniformly low, with no differences in treatment effects observed. 展开更多
