[Acupuncture combined with repetitive transcranial magnetic stimulation for post-stroke depression: a randomized controlled trial].

OBJECTIVE: To observe the curative effect of Shugan Tiaoshen (soothing liver and regulating mind) acupuncture combined with repetitive transcranial magnetic stimulation (rTMS) in the treatment of post-stroke depression (PSD), and to explore its mechanism. METHODS: Ninety patients of PSD were randomly divided into an acupuncture+rTMS combination group (30 cases), a rTMS combination group (30 cases, 1 case dropped off) and a western medication group (30 cases, 1 case dropped off). The western medication group was treated with escitalopram oxalate tablets, 10 mg orally each time, once a day; on the basis of the treatment in the western medication group, the rTMS combination group was additionally given rTMS, and the frequency was 20 Hz, 20 min each time, once a day, 5 times a week; on the basis of the treatment in the rTMS combination group, the acupuncture+rTMS combination group was additionally treated with Shugan Tiaoshen acupuncture at Baihui (GV 20), Sishencong (EX-HN 1), Yintang (GV 24+), Shenting (GV 24), etc. for 40 min each time, once a day, weekly 5 times, and each group was treated for 4 weeks. Before and after treatment, the scores of Hamilton depression scale-17 (HAMD-17), Montreal cognitive assessment scale (MoCA), Pittsburgh sleep quality index (PSQI) were observed, and serum levels of 5-hydroxytryptamine (5-HT) and brain-derived neurotrophic factor (BDNF) were detected in each group. RESULTS: After treatment, the HAMD-17 scores in the three groups were lower than those before treatment (P<0.01), and the PSQI scores in the acupuncture+rTMS combination group and the rTMS combination group were lower than those before treatment (P<0.01); the above indexes in the acupuncture+rTMS combination group and the rTMS combination group were lower than those in the western medication group (P<0.05), and the PSQI score in the acupuncture+rTMS combination group was lower than that in the rTMS combination group (P<0.05). After treatment, the MoCA scores and serum BDNF levels in the acupuncture+rTMS combination group and the rTMS combination group were higher than those before treatment (P<0.01), and the serum 5-HT levels in the three groups were higher than those before treatment (P<0.01); and the above indexes in the acupuncture+rTMS combination group and the rTMS combination group were higher than those in the western medication group (P<0.05), and which in the acupuncture+rTMS combination group were higher than those in the rTMS combination group (P<0.05). CONCLUSION: On the basis of western medication escitalopram oxalate, the addition of Shugan Tiaoshen acupuncture combined with rTMS therapy can effectively improve cognitive function and sleep quality in patients with PSD, and the effect is better than that of western medication alone or rTMS combined with western medication. Its mechanism of action may be related to the increase of peripheral serum 5-HT and BDNF levels.

[Hydrochemistry Characteristics and Estimation of the Dissolved Inorganic Carbon Flux in the Caohai Lake Wetland Catchment of Guizhou Province].

The Caohai Lake wetland in Weining County, Guizhou Province, is the largest karst wetland in China, and karst groundwater is an essential source of recharge and material. This study collected groundwater from the Caohai Lake catchment during the wet season, dry season, and flat season, and the main ion components of the groundwater were analyzed. The hydrochemistry characteristics and main ion sources of the groundwater were revealed, and the preliminary estimates of the karst carbon sink flux in the Caohai Lake catchment were calculated based on the solute load method. The results indicated that the water chemistry of the groundwater in the Caohai Lake catchment is primarily the HCO3-Ca type, and individual groundwater points in the southeast are the SO4-Ca type during the flat season. The dominant ions in the groundwater are Ca2+, Mg2+, and HCO3-. Seasonally, the average concentrations of SO42- and Mg2+ decreased in the order of flat season>dry season>wet season, while the average concentration of NO3- decreased in the order of wet season>dry season>flat season, and the seasonal variation of the other ions were not significant. Spatially, the concentrations of Ca2+ and HCO3- in the groundwater in the northern part of Caohai Lake, of K+, Na+, and Cl- in the southwest, and of Mg2+, NO3-, and SO42- in the southeast were relatively high. Ca2+, Mg2+, and HCO3- in the groundwater were primarily controlled by the dissolution of carbonate rocks, and carbonic acid, sulfuric acid and nitric acid were all involved in the weathering of carbonate rocks in the catchment. Most of the NO3- in the groundwater was affected mostly by the soil nitrogen and domestic sewage, while NO3- in the southeast groundwater was primarily affected by agricultural activities. The sources of K+, Na+, Cl-, and SO42- exhibited no obvious temporal and spatial differences, and the K+, Na+, and Cl- were mainly affected by human activities, while SO42- was mostly derived from the dissolution of sulfur compounds in the formation. The studied area has a high proportion of allogenic acids (sulfuric acid and nitric acid) participating in the weathering of carbonate rocks, which is the highest in the flat season and the lowest in wet season. After deducting the proportion of allogenic acids participating in the weathering of carbonate rocks, the average inorganic carbon flux in the Caohai Lake catchment is preliminarily estimated to be approximately 181.5 t·a-1, and the average karst groundwater transport of HCO3- to Caohai Lake is approximately 1144.1 t·a-1.

[Research progress on the mechanism of acupuncture and moxibustion in treatment of endometriosis].

The clinical and experimental researches of acupuncture and moxibustion on endometriosis during past 15 years were collected. The research progress underling the mechanism of acupuncture and moxibustion on endometriosis was summarized. By taken Chinese characters, i.e. "acupuncture-moxibustion" and "endometriosis" as well as the English words, i.e. "acupuncture therapy" and "endometriosis" as the searching words, the relevant articles were retrieved from Pubmed, Embase, Chinese China National Knowledge Infrastructure, Wanfang Database, Chongqing VIP and the China Biology Medicine Disc etc. The retrieval time was from January 2003 to October 2018. As a result, 41 articles of clinical studies and 18 articles of animal experiments were screened. Of them, 20 articles (including 18 articles of animal experiments and 2 articles of clinical trial) are related to the mechanism underling acupuncture and moxibustion on endometriosis. In term of the impacts on growth factors, enzymes and enzyme inhibitors, the mechanism of acupuncture and moxibustion was explored on the analgesia for endometriosis, the inhibition of ectopic tissue angiogenesis and invasive adhesion, as well as the regulation of immune function and endocrine. Moreover, the limitation and prospect on the current researches were proposed so as to provide the more reliable evidence for clinical treatment of endometriosis with acupuncture and moxibustion.

Dimorpholinium tetra-chlorido-cobaltate(II).

In the title mol-ecular salt, (C(4)H(10)NO)(2)[CoCl(4)], the morpholinium cations adopt chair conformations and the tetra-chloridocobaltate(II) anion is significantly distorted from regular tetra-hedral geometry [Cl-Co-Cl = 102.183 (19)-117.59 (2)°]. The Co-Cl bond lengths for the chloride ions not accepting hydrogen bonds are significantly shorter than those for the chloride ions accepting such bonds. In the crystal, the components are linked by N-H⋯O and N-H⋯Cl and bifurcated N-H⋯(O,Cl) hydrogen bonds to generate (100) sheets.
