OBJECTIVE:To provide the evidence for the efficacy of acupoint application(AA)for patients with diarrhea in a real-world setting.METHODS:This study is a national multicenter retrospective cohort study.Our study consecutively collected outpatient medical records of patients with diarrhea from hundreds of primary hospitals nationwide registered in Chun Bo Wan Xiang cloud platform from 22nd August,2020 to 5th November,2020.The patients were divided into the treatment group and the control group according to patient's condition and willingness.The control group was treated with Western Medicine,oral Chinese Medicine decoction,or both.The treatment group was added with AA based on the control group.Multiple logistic regression was used to evaluate the independent efficacy of AA in diarrheal recovery on the 3rd,7th,14th and 28th day.As a next step,we also performed stratified analysis and likelihood ratio test(LRT).Sensitivity analyses included propensity score matching(PSM),four PSM-related analyses and E-value.RESULTS:The treatment group showed better efficacy than the control group on the 14th and 28th day[the 14th day:OR=1.58,95%CI(1.15,2.19),P=0.005;the 28th day:OR=2.03,95%CI(1.43,2.88),P<0.001].No difference was observed in efficacy of AA for the treatment of diarrhea among the subgroups(P>0.05).PSM-related analyses confirmed the efficacy of AA in diarrheal recovery.The findings are unlikely to be nullified by an unmeasured confounding variable according to the results of E-values.CONCLUSIONS:The efficacy in the treatment group was significantly more improved than that in the control group on the 14th and 28th day.

Point application with Angong Niuhuang sticker protects hippocampal and cortical neurons in rats with cerebral ischemia

Angong Niuhuang pill, a Chinese materia medica preparation, can improve neurological func-tions after acute ischemic stroke. Because of its inconvenient application and toxic components （Cinnabaris andRealgar）, we used transdermal enhancers to deliverAngong Niuhuang pill by modern technology, which expanded the safe dose range and clinical indications. In this study, Angong Niuhuang stickers administered at different point application doses （1.35, 2.7, and 5.4 g/kg） were administered to theDazhui （DU14）, Qihai（RN6） andMingmen （DU4） of rats with chronic cerebral ischemia, for 4 weeks. The Morris water maze was used to determine the learning and memory ability of rats. Hematoxylin-eosin staining and Nissl staining were used to observe neuronal damage of the cortex and hippocampal CA1 region in rats with chronic cerebral ischemia. The middle- and high-dose point application ofAngong Niuhuangstickers attenuated neuronal damage in the cortex and hippocampal CA1 region, and improved the memory of rats with chronic cerebral ischemia with an efifcacy similar to interventions by electroacupuncture at Dazhui （DU14）,Qihai （RN6） andMingmen （DU4）. Our experimental ifndings indicate that point application withAngong Niuhuang stickers can improve cognitive function after chronic cerebral ischemia in rats and is neuroprotective with an equivalent efifcacy to acupuncture.

Expressions of apoptosis-related proteins in rats with focal cerebral ischemia after Angong Niuhuang sticker point application

In this study, we extracted and purified components in the Angong Niuhuang pill. Then we applied transdermal enhancers to Angong Niuhuang stickers by modern technology. The Angong Niuhuang sticker includes extracts from curcuma, berberine hydrochloride, baicalin, geniposide, borneol, and musk. Angong Niuhuang stickers at different point application doses （1.35, 2.7, and 5.4 g/kg） were administered to Dazhui （DU14）, Qihai （RN6） and Mingmen （DU4）. Rats in the different dose point application and acupuncture groups were continuously administered for 7 days. Then a middle cerebral artery occlusion model was prepared for simulating human cerebral ischemia. Twelve hours later, expressions of Bcl-2, Bax and p53 protein in hippocampal CA1 were detected with immunohistochemistry. The expression level of Bcl-2, an anti-apoptotic protein, significantly increased in the high-, medium- and low-dose point application groups and the acupuncture group, while the expression of the pro-apoptotic proteins, Bax and p53, significantly decreased compared with the middle cerebral artery occlusion rats; and the Bcl-2/Bax ratio was significantly increased. The difference was noticeable for the high-dose point application group, which showed statistical difference compared with the low-dose point application group and the acupuncture group. Our experimental findings indicate that point application with Angong Niuhuang stickers promotes the expression of Bcl-2, and inhibits the expressions of Bax and p53 in the hippocampal CA1 area of rats after focal cerebral ischemia. Thus, point application of Angong Niuhang stickers protects brain tissues from cerebral ischemia.

Three-dimensional(3D)parametric measurements of individual gravels in the Gobi region using point cloud technique

Gobi spans a large area of China,surpassing the combined expanse of mobile dunes and semi-fixed dunes.Its presence significantly influences the movement of sand and dust.However,the complex origins and diverse materials constituting the Gobi result in notable differences in saltation processes across various Gobi surfaces.It is challenging to describe these processes according to a uniform morphology.Therefore,it becomes imperative to articulate surface characteristics through parameters such as the three-dimensional(3D)size and shape of gravel.Collecting morphology information for Gobi gravels is essential for studying its genesis and sand saltation.To enhance the efficiency and information yield of gravel parameter measurements,this study conducted field experiments in the Gobi region across Dunhuang City,Guazhou County,and Yumen City(administrated by Jiuquan City),Gansu Province,China in March 2023.A research framework and methodology for measuring 3D parameters of gravel using point cloud were developed,alongside improved calculation formulas for 3D parameters including gravel grain size,volume,flatness,roundness,sphericity,and equivalent grain size.Leveraging multi-view geometry technology for 3D reconstruction allowed for establishing an optimal data acquisition scheme characterized by high point cloud reconstruction efficiency and clear quality.Additionally,the proposed methodology incorporated point cloud clustering,segmentation,and filtering techniques to isolate individual gravel point clouds.Advanced point cloud algorithms,including the Oriented Bounding Box(OBB),point cloud slicing method,and point cloud triangulation,were then deployed to calculate the 3D parameters of individual gravels.These systematic processes allow precise and detailed characterization of individual gravels.For gravel grain size and volume,the correlation coefficients between point cloud and manual measurements all exceeded 0.9000,confirming the feasibility of the proposed methodology for measuring 3D parameters of individual gravels.The proposed workflow yields accurate calculations of relevant parameters for Gobi gravels,providing essential data support for subsequent studies on Gobi environments.
