Objective:To explore the effect of Zhuyu Xiaozhong Decoction combined with warm acupuncture and moxibustion on rotator cuff injury of qi stagnation and blood stasis type.Methods:A total of 120 patients with rotator cuff injury of qi stagnation and blood stasis type treated at the First Hospital of Hunan University of Chinese Medicine from October 2021 to October 2023 were randomly divided into a control group ( n=60) and an observation group ( n=60) according to the random drawing method. The control group received routine treatment, while the observation group received Zhuyu Xiaozhong Decoction combined with warming acupuncture and moxibustion on this basis. Two groups of treatment effects were compared, including total effective rate, inflammation indicators, pain status, shoulder joint function and range of motion, and quality of life. Visual Analog Scale (VAS), Shoulder Joint Function Rating Scale (CMS), and Quality of Life Comprehensive Assessment Questionnaire (GQOLI-74) were used to evaluate patients′ pain status, shoulder joint function, and quality of life, respectively. Results:After treatment, the total effective rate of the observation group was higher than that of the control group, and the difference was statistically significant ( P<0.05); Before treatment, there was no statistically significant difference in the levels of serum C-reactive protein (CRP), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) between the two groups (all P>0.05); After treatment, the levels of serum CRP, IL-6, and TNF-α in both groups were lower than before treatment, and the levels of serum CRP, IL-6, and TNF-α in the observation group were lower than those in the control group after treatment (all P<0.05). Before treatment, there was no statistically significant difference in VAS scores and GQOLI-74 total scores between the two groups (all P>0.05); After treatment, the VAS scores of both groups were lower than before treatment, and the total GQOLI-74 score was higher than before treatment. In addition, the VAS score of the observation group was lower than that of the control group after treatment, and the total GQOLI-74 score was higher than that of the control group, with statistical significance (all P<0.05). Before treatment, there was no statistically significant difference in CMS scores, abduction, flexion, and extension angles between the two groups (all P>0.05); After treatment, the CMS scores of both groups were higher than before treatment, and the angles of abduction, flexion, and extension were greater than before treatment. The CMS scores of the observation group were higher than those of the control group after treatment, and the angles of abduction, flexion, and extension were greater than those of the control group, with statistical significance (all P<0.05). Conclusions:Zhuyu Xiaozhong Decoction combined with warm acupuncture and moxibustion can achieve a better clinical effect in the treatment of rotator cuff injury of qi stagnation and blood stasis type, which can control the inflammatory reaction of the body, alleviate pain symptoms, improve shoulder joint function and mobility, and optimize the quality of life.

Objective:Peritoneal free cancer cells can negatively impact disease progression and patient outcomes in gastric cancer.This study aimed to investigate the feasibility of using golden-angle radial sampling dynamic contrast-enhanced magnetic resonance imaging(GRASP DCE-MRI)to predict the presence of peritoneal free cancer cells in gastric cancer patients.Methods:All enrolled patients were consecutively divided into analysis and validation groups.Preoperative magnetic resonance imaging(MRI)scans and perfusion were performed in patients with gastric cancer undergoing surgery,and peritoneal lavage specimens were collected for examination.Based on the peritoneal lavage cytology(PLC)results,patients were divided into negative and positive lavage fluid groups.The data collected included clinical and MR information.A nomogram prediction model was constructed to predict the positive rate of peritoneal lavage fluid,and the validity of the model was verified based on data from the verification group.Results:There was no statistical difference between the proportion of PLC-positive cases predicted by GRASP DCE-MR and the actual PLC test.MR tumor stage,tumor thickness,and perfusion parameter Tofts-Ketty model volume transfer constant(Ktrans)were independent predictors of positive peritoneal lavage fluid.The nomogram model featured a concordance index(C-index)of 0.785 and 0.742 for the modeling and validation groups,respectively.Conclusions:GRASP DCE-MR could effectively predict peritoneal free cancer cells in gastric cancer patients.The nomogram model constructed using these predictors may help clinicians to better predict the risk of peritoneal free cancer cells being present in gastric cancer patients.

The aim of this study was to compare the immune responses of C57BL/6 mice immunized with two pathogens, foot-and-mouth disease virus (FMDV) and Senecavirus A (SVA), and to provide clues for revealing the regulatory mechanisms of acquired immunity. Inactivated and purified FMDV and SVA antigens were used to immunize C57BL/6 mice respectively, and the mice immunized with PBS were taken as the control. The percentages of Th1 and Th2 cells in the spleen lymphocytes of mice in each group were analyzed by flow cytometry at 14 and 28 days after immunization. RNA-Seq was performed for the spleen. Mouse macrophages were stimulated with the antigens in vitro to examine the expression of the differentially expressed genes (DEGs) screened out. The results showed that 14 days after immunization, there was no significant difference in the magnitude of the Th1/Th2 immune response elicited by the FMDV and SVA antigens. After 28 days, the magnitudes of the Th1 and Th2 immune responses elicited by the SVA antigen were higher than those elicited by the FMDV antigen. RNA-Seq revealed two common DEGs, Rsad2 and Tspan8, between the two immunization groups, which indicated that the two genes may be involved in the activation of the Th1/Th2 immune responses by FMDV and SVA antigens. FMDV and SVA antigens stimulated macrophages to secrete interleukin (IL)-12 and IL-33 in vitro, and the expression of Tspan8 and Rsad2 was consistent with the RNA-Seq results. The expression of Rsad2 was regulated by type I interferons (IFNα, IFNβ). In this study, we obtained the DEGs involved in the immune responses to the two antigens in mouse spleen, which provides a molecular basis for investigating the immune response mechanisms induced by FMDV and SVA.

Objective:Exploring the performance characteristics of spontaneous nystagmus（SN） in video-head impulse test（vHIT） and its possible effects on saccade. Methods:Vestibular function tests such as vHIT and SN were conducted in 48 patients with acute unilateral vestibulopathy（AUVP）. The saccade characteristics of vHIT in patients without SN and those with SN were analyzed, as well as the expression characteristics of SN in vHIT. Results:Among the 48 AUVP patients, there were 34 cases with SN, including 31 cases with saccade on the healthy side, 11 cases with both the same and opposite directions of eye movement, 19 with the opposite only, 1 with same direction only, and 3 cases without saccade. There were 14 patients without SN, of whom 10 showed saccade on the healthy side, including 4 with both eye movements in the same and opposite direction, 2 in the opposite direction only, 4 in the same direction only, and 4 without saccade. There is a correlation between reverse saccade on the healthy side and the presence of SN in patients. SN in vHIT can appear opposite to the direction of eye movement on the healthy side, while on the affected side it can appear the same as the direction of eye movement and may cause more discrete overt saccade. 32 patients in the acute phase（≤2 w）, 29 patients with SN, SN intensity of（6.7 ± 3.2） °/s, and 3 patients without SN. 16 cases in non acute phase（>2 w）, 5 cases with SN, SN intensity of（3.7 ± 2.1） °/s, and 11 cases without SN. In the acute phase there were 30 cases of saccade on the healthy side, 10 cases with both the same and opposite direction of eye movement, 18 cases with only the opposite direction, 2 cases with only the same direction and 2 cases without saccade. There is a correlation between the duration of the disease and the occurrence of reverse saccade on the healthy side. The intensity cut off point of SN for reverse saccade is 2.1 °/s in the healthy lateral semicircular canal vHIT. Conclusion:Compensatory saccades and SN waves with similar waveforms are mostly present in vHIT in AUVP patients. SN wave is in the opposite direction of the normal side and eye movement wave, and the affected side and dominant saccade direction are in the same direction and mixed together, which can affect the dispersion and amplitude of overt saccade in vHIT. Accurate identification of SN in vHIT of AUVP patients is not only the key factor to identify compensatory saccade, but also can provide help for the diagnosis and compensatory assessment of AUVP.

OBJECTIVE To extract and isolate the four chemical components of Yao medicine Ventilago leiocarpa， and to conduct identification and content determination for them. METHODS The chemical components of V. leiocarpa were separated and purified by solvent extraction， extraction， silica gel column chromatography and preparative liquid chromatography； then the chemical structures of four isolated compounds were identified based on their spectral data. The contents of four components were determined by high performance liquid chromatography（HPLC）-quantitative analysis of multi-components by single-marker （QAMS） method， with the following chromatographic conditions： chromatographic column was Echway GowonTM C18 （250 mm× 4.6 mm， 5 μm）. The mobile phase was acetonitrile-0.1% phosphoric acid for gradient elution； the detection wavelength was 269 nm， and the column temperature was 25 ℃ . Using emodin as internal reference， the relative correction factors （fi/s） between emodin and the other 3 components were established and used to calculate the content. At the same time， the content of each component was calculated with the external standard method （ESM）， and the differences between these two methods were compared. RESULTS Four compounds were isolated from V. leiocarpa， and they were identified as emodin， frangulin A， pleuropyrone A， emodin-8-O-β-D-glucoside. The result of HPLC-QAMS showed that the fi/s of pleuropyrone A， emodin-8-O-β-D- glucoside and frangulin A were 1.147 2， 0.874 7 and 0.644 4， respectively. The content of these four components was measured as a good linearity （r≥0.999 6）； relative standard deviation （RSD） of precision， stability and reproducibility tests were all lower than 2.00%， and average recoveries were E-mail：dearhuangjianyou@126.com 99.41%-100.46%（RSD≤2.05%）. There was no significant difference between QAMS method and ESM （RSD＜3.00%）. CONCLUSIONS Emodin， frangulin A， pleuropyrone A and emodin- 8-O-β-D-glucoside are isolated from V. leiocarpa； among them， the last three components are all isolated from for the first time. The established HPLC-QAMS method is accurate and reliable for the determination of 4 components in V. leiocarpa， and can used for quality control of V. leiocarpa.
