Vertical root distribution characters of Robinia pseudoacacia on the Loess Plateau in China

On the Loess Plateau, water is the main limiting factors for vegetation growth. Root distribution characters have special ecological meaning as it reflected the utilizations of trees to the environments. Even-aged stands ofRobinia pseudoacacia on slope lands facing south and north were selected as sampling plots for root distribution investigation. Investigatiing results showed that indicated that on all sites, root biomass decreased with depth, and the distribution depth of fine root was deeper than that of coarser root. The results of variance analysis indicated that there were great differences in root biomass among different diameter classes, and coarser root was the main sources of variance, and the root biomass, especially fine root (?<3mm) biomass on northern exposition sites was bigger than that on southern exposition sites. Analysis of the vertical root distribution parameters, root extinction coefficient, β indicated that the value of β on northern exposition was more than 0.982, while the value of β on southern exposition was less than 0.982, which indicated that the vertical root distribution depth ofRobinia pseudoacacia on southern exposition was deeper than that on southern exposition. And the distribution depth of fine roots (Φ<1mm) was deeper than that of thicker roots(Φ<3mm), which was in favor of the uptake of water and nutrients from deeper layers, helped the trees to adapt the arid environment, and promoted the growth of the upper parts of the tree.

Studies of Stability in Electrical Property and Sensitivity of Polypyrrole Conductive Fabrics Used for Intelligent Flexible Sensors

Electrically conducting fabrics used as flexible sensors can be produced by vacuumed vapor deposition.The research of what impacts the wide and reliable application of the flexible sensors shows that the stability of flexible sensors is one of the critical issues.The electrical performance of weft knitted fabrics in course and wale direction does not show significant differences under different ambient conditions,which include time,temperature,and relative humidity.Tests of stimuli responding sensitivity of conductive fabrics indicate that the sensitivity keeps at a constant level and the average sensitivity is stable over 38 days.

First record of water mite from Tibet with an updated key to the genus Sperchon(Acari: Hydrachnidia: Sperchontidae) from China

Tibet is a biodiversity-rich area in China. But until now, no water mites have been recorded from Tibet. In this study, two water mite species, Sperchon glandulosus Koenike, 1886 and Sperchon plumifer Thor, 1902 are reported for the first time from Tibet, and Sperchon glandulosus is newly recorded from China. Descriptions and illustrations of Sperchon glandulosus are given herein. DNA barcodings for the two species are also referenced. A key to the 22 species（females） in the genus Sperchon from China is presented.

Observation on clinical efficacy of acupuncture combined with direct moxibustion with fine-strip moxa for 62 cases of herpes zoster

Objective To evaluate the clinical effect of acupuncture combined with direct moxibustion with fine-strip moxa for herpes zoster. Methods Sixty-two patients with herpes zoster were randomly divided into two groups according to attendance number, 32 in acupuncture group and 30 in western medicine group. The patients in the acupuncture group were treated by acupuncture at the nidus-related nerve segments Jiaji （夹脊 EX-B2） in combination with direct moxibustion with fine-strip moxa, while the patients in the western medicine group were treated by oral valaciclovir hydrochloride, vitamin B1, vitamin B12. The times of response, incrustation and decrustation were observed respectively, and pain relief degree of the two groups were compared. Results The response time, incrustation time and decrustation time of the acupuncture group were all less than those of the western medicine group [（1.74±0.43） days vs （3.86±0.58） days, （2.03±0.52） days vs （5.46±0.65） days, （5.14±0.33） days vs （8.34±0.59） days, all P〈O.05]. The pain relief degree （VAS score）, and pain duration in the acupuncture group were all higher obviously than those of the western medicine group [（10.41±12.1） vs （15.63±11.39）, （4.78±0.45） days vs （8.12±0.63） days, all P〈O.05]. The total effective rate of the acupuncture group was 96.9% （31/32）and that of the western medicine group was 90% （27/30）, thus the therapeutic effect of acupuncture group was better than that of western medicine group （P〈0.05）. Conclusion The therapeutic effect of acupuncture combined with direct moxibustion with fine-strip moxa is remarkable. It can effectively control the development of herpes zoster, alleviate pain and shorten therapy periods. It is worthy to be promoted and applied.

珍爱生命

小时候,我家村子西头的山冈上,有三棵老松树,小木桶儿那么粗,五六层楼那么高。听奶奶说,我还没出生时,村里有个男孩儿爬到中间那棵松树上去掏鸟蛋,突然鸟窝里蹿出一条蛇来,吓得他掉下来摔死了。从此,谁也不敢再爬那三棵老松树了。春末夏初,漫山遍野鸟语花香,生机无限。我最喜爱的小八哥儿,早已从南方飞回来,抢占了喜鹊的巢,开始哺育自己的孩子。据老人们讲,八哥儿是通人性的。

Observations on Therapeutic Effect of Back-Shu Acupoint in Treatment of Asthma

Objective： To investigate the therapeutic effect of Back-Shu acupoint in treating asthma. Methods： Sixty-one patients were randomly divided into a Back-Shu acupoint group, a acupuncture-moxibustion group and a acupuncture group. All the three groups were treated twice a week, 10 times made up a treatment course. The therapeutic effect was evaluated after three courses of treatment. Results and conclusion： The control and marked effective rate were significantly higher in the Back-Shu acupoint group and acupuncture-moxibustion groups than in the acupuncture group （P〈0.05）. They were slightly higher in the acupuncture-moxibustion group than in the Back-Shu acupoint group, but there was no statistically significant difference. The results indicated that the Back-Shu acupoints have a good therapeutic effect in treating asthma.

Low-frequency fluctuation amplitude analysis of resting-state fMRI for functional brain response differences between acupuncture and moxibustion at Zusanli(ST 36) in patient with functional dyspepsia

Objective： To compare and analyze functional brain response characteristics by applying acupuncture or moxibustion to Zusanli（ST 36） in patients with functional dyspepsia（FD） and investigate the differences of central action mechanism resulting from acupuncture or moxibustion.Methods： A total of eligible 24 FD cases were divided into two blood-oxygen-level dependent（BOLD） sequences for functional magnetic resonance imaging（fMRI） scan. The amplitude of low frequency fluctuation（ALFF） analyses were conducted on the data of location phase, structure phase, resting state before acupuncture/moxibustion, working state during acupuncture/moxibustion and resting state after acupuncture/moxibustion using Data Processing Assistant for Resting-State fMRI（DPARSF） software.Results： Acupuncture and moxibustion produced significant differences in functional brain response. The working state during acupuncture/moxibustion mainly decreased ALFF values in the right supramarginal gyrus, right superior parietal lobule, right frontal gyrus, upper right occipital lobe, right precuneus and right cingulate gyrus. At the same time, it increased ALFF values in the left cerebellum, right caudate nucleus, right cerebellum and left inferior gyrus. The differences during the resting state after acupuncture/moxibustion were significantly smaller than the working state in intensity and size. It mainly resulted in decrease in ALFF values in the right postcentral gyrus and right supramarginal gyrus and increase in ALFF values in the left precuneus, orbital part of inferior frontal gyrus and right cerebellar peduncles.Conclusion： Needling and moxibustion at Zusanli（ST 36） can produce significant differences in immediate functional brain response.

Objective： To observe the clinical effects of collateral-pricking and cupping therapy plus moxibustion for localized neurodermatitis. Methods： A total of 94 cases with localized neurodermatitis were randomly divided into two groups by their visit order, 47 cases in each group. The cases in the treatment group were treated by bleeding method with a plum blossom needle, cupping method and moxibustion. The cases in the control group were treated by subcutaneous injection of Triamcinolone Acetonide Acetate Injection. Results： After treatment, the curative rate and total effective rate were respectively 80.9% and 100% in the treatment group and were 48.9% and 87.2% in the control group. The differences in the curative rate and total effective rate between the two groups were statistically significant （P〈0.01, P〈0.05）. Conclusion; Bleeding method by a plum blossom needle, in combination with cupping method and moxibustion, is an effective therapy for localized neurodermatitis.
