Objective To discuss medicine using regularity of Yan Shiyun’s treatment for arrhythmia. Methods Medical cases of arrhythmia treated by Yan Shiyun were collected. The method of frequency of SPSS19.0 was used to analyze the frequency of single herb and common prescriptions. Results Totally 112 medical cases were collected. Three different kinds of arrhythmia in totally 315 prescriptions were collected and 18 same herbs were used in the 20 highest frequently used herbs. The first two were Chuanxiong Rhizoma and Persicae Semen. Buyang Huanwu Decoction is the most commonly used prescription, followed by Zhenwu Decoction. Conclusion Most Chinese herbal medicine included in Yan Shiyun’s prescriptions can tonify qi and invigorate the circulation of blood. The medicine use is concentrated, and composition law is clear.

Based on repeated experiments as well as continuous researching and improving, an efficient scheme to measure velocity and displacement of the coxa and knee movements based on video image processing technique is presented in this paper. The scheme performed precise and real-time quantitative measurements of 2D velocity or displacement of the coxa and knee using a video camera mounted on one side of the healing and training beds. The beds were based on simplified pinhole projection model. In addition, we used a special-designed auxiliary calibration target, composed by 24 circle points uniformly located on two concentric circles and two straight rods which can rotate freely along the concentric center within the vertical plane, to do the measurements. Experiments carried out in our laboratory showed that the proposed scheme could basically satisfy the requirements about precision and processing speed of such kind of system, and would be very suitable to be applied to smart evaluation/training and healing system for muscles/balance function disability as an advanced and intuitional helping method.

Objective:To investigate the effect of oral immunotherapy with donor human milk on feeding tolerance in premature infants with very low birth weight.Methods:A total of 94 extremely low birth weight preterm infants admitted to the neonatal Intensive Care Unit of Cangzhou People's Hospital from August 2022 to February 2024 were selected, These infants were randomized at 1:1 into 2 groups (47 cases each) using random number method. The control group were given oral 0.9% sodium chloride (oral drip), while the experimental group were given donor human milk (oral drip). General information were collected, including gender, delivery method, twins or not, small for gestational age or not, birth weight, gestational age, intestinal feeding of dairy products, and so on. Total intestinal feeding time, length of hospital stay and feeding intolerance were compared between groups.Results:The total intestinal feeding time and length of hospital stay were significantly shorter in the experimental group compared with the control group ( P<0.05). The incidence of feeding intolerance in the experimental group was also lower than that in the control group ( P<0.05). Conclusion:Oral immunotherapy with donor human milk can improve the feeding tolerance in premature infants with very low birth weight and shorten the hospital stay.

OBJECTIVE: To investigate the effect of the chemoprotectant tempol on the anti-tumor activity of cisplatin (DDP). METHODS: The cellular toxicity of tempol in human colon cancer SW480 cells and mouse colon cancer CT26 cells were evaluated using MTT and cell counting kit-8 assays. CalcuSyn software analysis was used to determine the interaction between tempol and DDP in inhibition of the cell viability. A subcutaneous homograft mouse model of colon cancer was established. The mice were randomly divided into control group, tempol group, cisplatin group and tempol + DDP treatment group with intraperitoneal injections of the indicated agents. The tumor size, body weight and lifespan of the mice were measured, and HE staining was used to analyze the cytotoxic effect of the agents on the kidney and liver. Immunohistochemistry and Western blotting were performed to detect the expression of Bax and Bcl2 in the tumor tissue, and TUNEL staining was used to analyze the tumor cell apoptosis. The level of reactive oxygen species (ROS) in the tumor tissue was determined using flow cytometry. RESULTS: Tempol showed inhibitory effects on the viability of SW480 and CT26 cells. CalcuSyn software analysis showed that tempol had a synergistic anti-tumor effect with DDP (CI < 1). In the homograft mouse model, tempol treatment alone did not produce obvious anti-tumor effect. HE staining showed that the combined use of tempol and DDP alleviated DDP-induced fibrogenesis in the kidneys, but tempol also reduced the anti-tumor activity of DDP. Compared with the mice treated with DDP alone, the mice treated with both tempol and DDP had a significantly larger tumor size ( < 0.01) and a shorter lifespan ( < 0.05). Tempol significantly reversed DDP-induced expression of Bax and Bcl2 in the tumor tissue and tumor cell apoptosis ( < 0.001), and obviously reduced the elevation of ROS level in the tumor tissue induced by DDP treatment ( < 0.05). CONCLUSIONS Tempol can attenuate the anti-tumor effect of DDP while reducing the side effects of DDP. Caution must be taken and the risks and benefits should be carefully weighed when considering the use of tempol as an anti-oxidant to reduce the toxicities of DDP.
