Soil bacterial community responses to revegetation of moving sand dune in semi-arid grassland.

Grasslands in semi-arid Northern China are widely desertified, thus inducing the formation of a large area of moving sand lands. Revegetation of the sandy land is commonly adopted to restore degraded grasslands. The structure of the soil microbial community might dramatically change during degradation and recovery because microorganisms are one of the major drivers of ecological process through their interactions with plants and soil. Assuming that soil properties are the key determinants of the structure of soil bacterial community within the same soil type, whether the vegetation type causes the significant difference in the structure of soil bacterial community during revegetation and restoration of the degraded grasslands remains poorly understood. Our study aimed to (1) investigate the response of soil bacterial communities to the changes during vegetation degradation and recovery and (2) evaluate whether the soil bacterial communities under plantations return to their native state. We detected the shifts in diversities and compositions of the soil bacterial communities and the relative abundance of dominant bacterial taxa by using the high-throughput Illumina MiSeq sequencing technique in an area covered by 32-year-old Caragana microphylla, Artemisia halodendron, Hedysarum fruticosum, Pinus sylvestris var. mongolica, Populus simonii, and Salix gordejevii sand-fixing plantations and in the native community (NC) dominated by elm, and moving sandy dune (MS). We found that the obtained operational taxonomic units by 16S rRNA gene sequencing and diversity index in MS were all significantly lower than those in NC, and the number and composition of dominant genera were significantly different between NC and MS. Interestingly, the compositions of bacterial communities and the dominant genera in different sand-fixation plantations (C. microphylla, A. halodendron, H. fruticosum, P. sylvestris var. mongolica, P. simonii, and S. gordejevii) were all similar to those of the native soil of NC, suggesting that the plantation type and soil properties exhibit a minimal effect on the compositions of soil microbial communities within a continuous landscape. These results revealed that the structure of the soil bacterial community of degraded sandy grassland (even degenerated into a mobile sand dunes) in semi-arid region can be reversibly restored by planting indigenous shrub or semi-shrub plantation on human time scales.

Effectiveness of electroacupuncture for polycystic ovary syndrome: study protocol for a randomized controlled trial.

BACKGROUND: Whether electroacupuncture is effective for patients with polycystic ovary syndrome is still inconclusive. Therefore, this study aims to evaluate the add-on effects of electroacupuncture to conventional drugs for the treatment of polycystic ovary syndrome. METHODS/DESIGN: This study is a two-center, open-labeled, randomized, controlled trial. A total of 116 eligible patients with polycystic ovary syndrome will be randomly allocated in a 1:1 ratio to the electroacupuncture plus clomiphene citrate group or to the clomiphene citrate group. Participants in the electroacupuncture plus clomiphene citrate group will receive electroacupuncture treatment in addition to clomiphene citrate capsules, whereas participants in the clomiphene citrate group will be prescribed clomiphene citrate capsules only. Electroacupuncture treatment will be performed from the fifth day of menstruation or withdrawal bleeding until the next menstruation, in three sessions per week for three menstrual cycles. The primary outcome is the ovulation rate. The secondary outcomes include the dominant follicle rate, mean number of dominant follicles, endometrial thickness, time point of ovulation, follicular size before ovulation, luteinizing hormone, estradiol level, and pregnancy rate. The measuring points for outcomes will be baseline and the completion of treatment. Any adverse events occurring during the trial process will be recorded. In addition, a quality-monitoring group independent from the research team will be set up to control the quality of the trial. DISCUSSION: The design and methodological rigor of this trial will allow for the collection of valuable data to evaluate the effectiveness of electroacupuncture for treating polycystic ovary syndrome. Therefore, this trial will contribute reliable evidence for use in clinical decision-making in acupuncture therapy of polycystic ovary syndrome as well as to future research in acupuncture for polycystic ovary syndrome.

[Regularities of Acupoint Combinations for Facial Paralysis in Chinese Ancient Times Analyzed in Accordance with Modern Complex Network Community Framework Partition].

OBJECTIVE: To analyze the characteristics of acupoint combinations (formula) for facial palsy in ancient lite-rature, so as to optimize the related acupoint prescriptions in clinical practice. METHODS: The database of ancient acupoint prescriptions for facial paralysis was established first after searching and collecting the related acu-moxibustion literature (178 categories as monographs, specific volumes of a book, etc.) by using key words of "facial palsy" or "deviation of the eye and mouth" including Chinese terms of "Diaoxianfeng ()" "Wopi ()"and "Kouwo()". The characteristics of acupoint selection were analyzed and acupoint prescriptions were optimized using bipartite network community structure partition. RESULTS: The results indicated that of the 56 acupoints for facial palsy collected in the literature, Shuigou (GV 26), Dicang (ST 4), Jiache (ST 6), Hegu(LI 4), Fengchi(GB 20), Zusanli (ST 36), Neiting (ST 44), Tinghui (GB 2), Chengjiang (CV 24) and Shangguan (GB 3) are the core acupoints in clinical application. The acupoints of Dicang (ST 4), Jiache (ST 6), Shuigou (GV 26), Fengchi(GB 20), Neiting (ST 44), Hegu (LI 4), Zusanli (ST 36), Lieque (LU 7), Shangguan (GB 3) and Erjian (LI 2) are most frequently selected for forming prescriptions.The optimized acupoint prescriptions are composed of Tinghui (GB 2), Fengchi (GB 20), Fengshi (GB 31), Xuanzhong (GB 39), Dicang (ST 4), Jiache (ST 6), Zusanli (ST 36), Dazhui (GV 14), Baihui (GV 20), Quchi (LI 11) and Jianyu (LI 15). Core acupoints were mainly distributed on the Stomach Meridian of Foot Yangming, Large Intestine Meridian of Hand Yangming and the Governor Vessel. Acupoints at the face and head are used more frequently than those in any other parts of the body. Specific acupoints are used more frequently than non-specific acupoints, among which Conf-luent Acupoints are most frequently used. CONCLUSIONS: In the treatment of facial paralysis in ancient China, selection of local acupoints is the basic principle and some specific acupoints are the core acupoints in ancient acupuncture prescriptions.

The A61N in patent and utility model patent were the most, which were mainly related to electrotherapy, magnetic therapy, radioactive therapy and ultrasound therapy, etc. The main content was acupuncture treatment devices and meridian treatment devices. The 24-01 in design patent was the most, involving fixation devices used by doctors, hospitals and laboratories, etc. CONCLUSIONS: Currently the majority of diagnosis and treatment devices of acupuncture is therapeutic apparatus, while the acupuncture diagnosis devices are needed.

Discovery of Acupoints and Combinations with Potential to Treat Vascular Dementia: A Data Mining Analysis.

The prevalence of vascular dementia (VaD) is high among the elderly. Acupuncture, a popular therapeutic method in China, can improve memory, orientation, calculation, and self-managing ability in VaD patients. However, in clinical acupuncture and acupuncture research, the selection of acupoints to treat VaD remains challenging. This study aimed to discover acupoints and acupoint combinations with potential for VaD based on data mining. After database searching and screening for articles on clinical trials evaluating the effects of acupuncture on VaD, 238 acupuncture prescriptions were included for further analysis. Baihui (GV 20), Sishencong (EX-HN 1), Fengchi (GB 20), Shuigou (GV 26), and Shenting (GV 24) appeared most frequently in the modern literature and are potential acupoints for VaD. Combinations between Baihui (GV 20), Sishencong (EX-HN 1), Fengchi (GB 20), Shenting (GV 24), Shuigou (GV 26), and Zusanli (ST 36) were most frequent and represent potential combinations for VaD treatment. These results provide a reference for the selection and combination of acupoints to treat VaD in clinical acupuncture and acupuncture research.

[Acupuncture status analysis in PROSPERO systematic review registry platform].

By searching the registry information of systematic review regarding acupuncture included before March 31, 2014 in PROSPERO systematic review registry platform, information in the project plan such as care gories of diseases, interventions, research team and the completion status was analyzed to make a comprehensive understanding on registry status of acupuncture systematic review in this platform. As a result, a total of 52 project plans was finally included. The health problem concerned was mainly painrelated diseases, and the interventions were mostly simple acupuncture or combination of acupuncture and moxibustion. The registered plan participated with Chinese team appeared comparatively late, which was featured with fewer independent projects and concentrated research organization, so its scientific research advantage in acupuncture did not present. In conclusion, it is believed that the consciousness on systematic review registry in domestic researchers needs to be improved, and researchers might take good advantages of the PROSPERO platform in the future.

[Discussion on disease spectrum treated with acupuncture at shenmen (HT 7) and its compatibility based on bibliometrics].

The modern literatures on the diseases treated with acupuncture at Shenmen (HT 7) were collected. Using literature statistical analysis in bibliometrics, the common compatibility of Shenmen (HT 7) and the disease spectrum were analyzed so as to provide the references of the diseases that can be treated with acupuncture at Shenmen (HT 7). It was found that 39 kinds of diseases and symptoms, mainly nerve system disedses, could be treated with acupuncture at Shenmen (HT 7), including insomnia, depression, anxiety and dementia. Shenmen (HT 7) was seldom used alone. Instead, it was commonly used along with Baihui (GV 20), Sanyinjiao (SP 6), Neiguan (PC 6), Sishencong (EX-HN 1) and Taicong (LR 3).

Effects of Electroacupuncture on Facial Nerve Function and HSV-1 DNA Quantity in HSV-1 Induced Facial Nerve Palsy Mice.

Acupuncture is a common and effective therapeutic method to treat facial nerve palsy (FNP). However, its underlying mechanism remains unclear. This study was aimed to investigate the effects of electroacupuncture on symptoms and content of HSV-1 DNA in FNP mice. Mice were randomized into four groups, an electroacupuncture treatment group, saline group, model animal group, and blank control group. Electroacupuncture was applied at Jiache (ST6) and Hegu (LI4) in electroacupuncture group once daily for 14 days, while electroacupuncture was not applied in model animal group. In electroacupuncture group, mice recovered more rapidly and HSV-1 DNA content also decreased more rapidly, compared with model animal group. We conclude that electroacupuncture is effective to alleviate symptoms and promote the reduction of HSV-1 in FNP.

Acupuncture Deqi Intensity and Propagated Sensation along Channels May, Respectively, Differ due to Different Body Positions of Subjects.

Acupuncture as an essential component of complementary and alternative medicine is gradually recognized and accepted by the mainstream of contemporary medicine. For obtaining preferable clinical effectiveness, Deqi is commonly regarded as efficacy predictor and parameter which is necessary to be achieved. Influential factors for acupuncture efficacy, like Deqi sensation as well as propagated sensation along channels (PSCs), enjoyed a long history in acupuncture basic research. Concerning this study, taking into account different positions on acupuncture Deqi sensation and PSCs, we would like to attest whether different body positions for subjects during needling procedure yield differed acupuncture Deqi sensation, particularly in terms of intensity, and PSCs. Methods. We used self-controlled method and selected 30 healthy subjects to perform needle insertion at Futu point (ST32) bilaterally. Then they were instructed to record the value of intensity of acupuncture sensation and the length and width of PSCs after removing the needle. Results. In regard to intensity of Deqi, kneeling seat position is stronger than supine position, accounting for 90% of the total number of subjects. In length of PSCs, kneeling seat position is greater than supine position, accounting for 56.7%. In width of PSCs, kneeling seat position is greater than supine position, accounting for 66.7%. Conclusion. Our findings show that needle inserting at Futu point (ST32) in kneeling seat position achieve better needle sensation and provide reference for clinical.
