ObjectiveTo establish the quality standards for Sennae Folium（Cassia angustifolia） dispensing granules based on standard decoctions. MethodsHigh performance liquid chromatography（HPLC） specific chromatograms were established for 15 batches of Sennae Folium（C. angustifolia） standard decoctions and 10 of Sennae Folium（C. angustifolia） dispensing granules from different manufacturers， and the similarity evaluation， hierarchical cluster analysis（HCA） and principal component analysis（PCA） were performed. Linear calibration with two reference substances（LCTRS） and quantitative analysis of multi-components by single-marker（QAMS） were established for the common peaks in the specific chromatograms to determine the contents of main components in the decoction pieces， standard decoctions and dispensing granules， and to calculate their transfer rates from decoction pieces to standard decoctions and dispensing granules. ResultsThe similarities of specific chromatograms of 15 batches of Sennae Folium（C. angustifolia） standard decoctions and 10 batches of Sennae Folium（C. angustifolia） dispensing granules were all greater than 0.95， and a total of 8 characteristic peaks were calibrated， and five of them were identified， including kaempferol-3，7-O-diglucoside， apigenin-6，8-di-C-glucoside， quercetin-3-O-gentianoside， sennoside B and sennoside A. HCA and PCA results showed that there were certain differences in the composition of different batches of standard decoctions， but no clustering was observed in the production area. As the standard decoctions， the extract rate of 15 batches of samples was 26.54%-45.38%， the contents of kaempferol-3，7-O-diglucoside， apigenin-6，8-di-C-glucoside， quercetin-3-O-gentianoside， sennoside B and sennoside A were 12.16-19.26， 2.57-4.94， 3.27-5.11， 6.75-11.39， 4.69-7.79 mg·g^-1， and their transfer rates from decoction pieces to standard decoctions were 45.41%-79.02%， 29.12%-55.07%， 40.52%-67.90%， 24.72%-49.12%， 27.54%-49.34%， respectively. The extract rates of Sennae Folium（C. angustifolia） dispensing granules（C8-C10） were 38.10%-39.50%， the transfer rates of the above five components from decoction pieces to dispensing granules were 72.85%-73.58%， 53.43%-53.94%， 40.19%-40.74%， 24.62%-25.00%， 28.65%-29.11%， respectively， which were generally consistent with the transfer rates from decoction pieces to standard decoctions. ConclusionCompared with the relative retention time method， LCTRS has higher prediction accuracy and is more suitable for chromatographic columns. The established quality control standard of Sennae Folium（C. angustifolia） dispensing granules based on standard decoction is reasonable and reliable， and all indicators of samples from different manufacturers are within the range specified based on the standard decoction， which can provide reference for the quality control and process research of this dispensing granules.

ObjectiveTo establish the specific chromatogram and quantitative analysis of multi-components by single-marker（QAMS） based on linear calibration using two reference substances（LCTRS）， explore the consistency between Hedyotis Herba dispensing granules and standard decoction， and evaluate the quality of the dispensing granules. MethodsHigh performance liquid chromatography（HPLC） specific chromatogram was established based on 15 batches of Hedyotis Herba standard decoction and 10 batches of the dispensing granules， and LCTRS was used to locate chromatographic peaks. The actual retention times of 7 characteristic peaks in the specific chromatogram was measured on 24 different types of C₁₈ columns， taking deacetyl asperulosidic acid and asperulosidic acid as the dual standard compounds， the retention times of the other 5 characteristic peaks were predicted and validated. Based on this， QAMS was developed to determine the contents of four components（deacetyl asperulosidic acid， deacetyl asperulosidic acid methyl ester， asperulosidic acid， and p-coumaric acid）. Then， the relative correction factors of deacetyl asperulosidic acid， deacetyl asperulosidic acid methyl ester and p-coumaric acid were calculated using the reference peak of asperulosidic acid in the dual standard compounds， and each component was quantified accordingly. Finally， the consistency between the dispensing granules and standard decoction was assessed by taking extract rate of the standard decoction， consistency of the specific chromatograms， contents and transfer rates of the indicator components as indexes， and the quality of the dispensing granules was evaluated. ResultsThere were 7 common peaks in the characteristic chromatogram of samples of Hedyotis Herba standard decoction and the dispensing granules， and four of them were identified by reference standards， namely deacetyl asperulosidic acid（peak 1）， deacetyl asperulosidic acid methyl ester（peak 3）， asperulosidic acid（peak 6） and p-coumaric acid（peak 7）. The similarity between the dispensing granules and the standard decoction was >0.9. The absolute deviation in the predicted retention time for each component by LCTRS was lower than that of the relative retention time method. The extract rate of the 15 batches of Hedyotis Herba standard decoction ranged from 7.89% to 14.60%， the contents of deacetyl asperulosidic acid， deacetyl asperulosidic acid methyl ester， asperulosidic acid and p-coumaric acid were 6.62-19.70， 3.83-17.99， 1.57-6.69， 1.62-4.52 mg·g^-1， and the transfer rates of these components from decoction pieces to the standard decoction were 22.89%-39.60%， 34.03%-62.24%， 24.25%-43.70%， and 40.58%-73.71%， respectively. The extract rate， index component contents and transfer rates from decoction pieces to the three batches of Hedyotis Herba dispensing granules（P1-P3）， produced by manufacturer A， were similar to those of the standard decoction prepared from the same batch of decoction pieces， and all fell within the specified range. The contents of the 4 indicator components in 7 batches of the dispensing granules（P4-P10） from manufacturers B-E were all within the range of the content converted from the standard decoction based on the quantity of the dispensing granules. ConclusionThe established specific chromatogram and QAMS based on LCTRS are reasonable and reliable. Based on the evaluation indicators of standard decoction yield， consistency of specific chromatograms， contents and transfer rates of the four index components， the 10 batches of Hedyotis Herba dispensing granules from various manufacturers have exhibited good consistency with the standard decoction， indicating that the current production process is relatively reasonable.

ObjectiveTo establish the specific chromatogram of Chuanxiong Rhizoma dispensing granules（CRdg）， and to evaluate its quality by chemometrics and two reference substances for determination of multiple components（TRSDMC）. MethodsHigh performance liquid chromatography（HPLC） specific chromatograms were established using 13 batches of CRdg from 7 manufacturers， and preliminary quality evaluation was performed by similarity evaluation and chemometrics analysis. Eight characteristic peaks in the specific chromatogram of CRdg were measured on 22 different types of C₁₈ columns， and the actual retention times were recorded. Taking chlorogenic acid（peak 1） and senkyunolide A（peak 8） as double standard compounds， the retention times of the eight characteristic peaks were predicted by linear calibration using two reference substances（LCTRS）， and the method was validated on three other columns of different brands. Taking chlorogenic acid as reference peak， the relative correction factor method（RCFM） was used to quantify cryptochlorogenic acid， caffeic acid， ferulic acid， senkyunolide I and senkyunolide A， and the results were compared with the external standard method（ESM）. ResultsThe similarities of specific chromatograms of 13 batches of CRdg were all >0.90， and a total of 8 characteristic peaks were calibrated， and six of them were identified， including chlorogenic acid（peak 1）， cryptochlorogenic acid（peak 2）， caffeic acid（peak 3）， ferulic acid（peak 5）， senkyunolide I（peak 6） and senkyunolide A（peak 8）. Through chemometric analysis， it was found that ferulic acid， chlorogenic acid， senkyunolide I and cryptochlorogenic acid were the main components causing quality difference in CRdg， and the accuracy of LCTRS in predicting the retention time of 8 characteristic peaks was superior to that of the relative retention time method（RRT）. Further comparison of the results obtained from RCFM and ESM showed that there was no statistically significant difference between the two methods. ConclusionA quality evaluation method for CRdg based on HPLC specific chromatogram and TRSDMC is established， its qualitative accuracy is better than that of RRT， the quantitative accuracy is similar to that of ESM， and 4 quality-differentiated components among different manufacturers are found. This method is stable and reliable， and has reference value for the quality evaluation of other dispensing granules.

Lymphatic metastasis is the main metastatic route for colorectal cancer, which increases the risk of cancer recurrence and distant metastasis. The properties of the lymph node metastatic colorectal cancer (LNM-CRC) cells are poorly understood, and effective therapies are still lacking. Here, we found that hypoxia-induced fibroblast activation protein alpha (FAPα) expression in LNM-CRC cells. Gain- or loss-function experiments demonstrated that FAPα enhanced tumor cell migration, invasion, epithelial-mesenchymal transition, stemness, and lymphangiogenesis via activation of the STAT3 pathway. In addition, FAPα in tumor cells induced extracellular matrix remodeling and established an immunosuppressive environment via recruiting regulatory T cells, to promote colorectal cancer lymph node metastasis (CRCLNM). Z-GP-DAVLBH, a FAPα-activated prodrug, inhibited CRCLNM by targeting FAPα-positive LNM-CRC cells. Our study highlights the role of FAPα in tumor cells in CRCLNM and provides a potential therapeutic target and promising strategy for CRCLNM.

Using the convenience sampling method, 98 patients with acute ischemic stroke who attended the Department of Neurology at the Third Hospital of Hebei Medical University from November 2021 to September 2022 were selected for the study, and the study population was divided into experimental group ( n=49) and control group ( n=49) using the random number table method. The control group received conventional care, and the experimental group received mindfulness-based stress reduction therapy for 8 weeks in addition to conventional care. Compared the scores of the Fear of Progression Questionnaire-Short Form (FoP-Q-SF), Stroke-Specific Quality of Life Scale (SS-QOL), and Pittsburgh Sleep Quality Index (PSQI) between the two groups of patients before and after intervention using two independent sample t-tests, and further compared the score spread of each scale before and after intervention between the two groups of patients using Mann-Whitney U test. Results:In the experimental group, 4 cases fell off and 3 cases had imperfect questionnaire information, while in the control group, 2 cases fell off and 5 cases had imperfect questionnaire information. Finally, 42 cases were included in each group. The 23 males and 19 females in the control group aged (48.31 ± 7.61) years old, while 25 males and 17 females in the experimental group aged (50.19 ± 8.64) years old. There was no significant difference in FoP-Q-SF, SS-QOL and PSQI scores between the two groups before intervention (all P>0.05). After intervention, the scores of FoP-Q-SF and PSQI in the experimental group (35.79 ± 7.04, 7.19 ± 2.58) were lower than those in the control group (38.52 ± 4.02, 9.45 ± 2.28), while the SS-QOL score (200.36 ± 21.75) was higher than that in the control group (185.41 ± 15.90), the differences were statistically significant ( t=2.19, -4.26, 3.60, all P<0.05). After intervention, the scores of FoP-Q-SF and PSQI in the experimental group were lower than those before intervention (39.69 ± 4.15, 10.00 ± 2.85), while the SS-QOL score was higher than that before intervention (176.93 ± 23.54), the differences were statistically significant ( t=4.80, 10.45, -11.43, all P<0.05). The score spreads of FoP-Q-SF, SS-QOL, and PSQI in the experimental group before and after intervention were 1.00 (0.00, 9.25), 20.00 (12.75, 32.75), 3 (1, 4), which were higher than 1.00 (-1.25, 2.00), 5.50 (1.00, 10.25), 0 (-1, 2) in the control group, the differences were statistically significant ( Z=-2.30, -5.74, -5.53, all P<0.05). Conclusions:Mindfulness-based decompression therapy can effectively relieve the fear of disease progression and improve the quality of sleep and life in patients with acute ischemic stroke.

Objective:To summarize the characteristics of color doppler flow imaging (CDFI) of ocular toxocariasis (OT) in children.Methods:A retrospective clinical study. From July 2014 to June 2020, 61 OT patients with 61 eyes diagnosed through clinical and laboratory testing in the Department of Ophthalmology of Beijing Tongren Hospital of Capital Medical University were included in the study. There were 45 males with 45 eyes and 16 females with 16 eye (male: female=2.81:1). Age were (6.93±2.50) years. The right eye and left eye were 29 and 32 eyes, respectively. Both eyes of the patient underwent two-dimensional ultrasound and CDFI examination. Two dimensional ultrasound was used to estimate the axial length (AL) of the affected eyes and healthy eyes on the opposite side. Among them, 52 cases were measured for AL using optical biometry and/or A-mode ultrasound. Vitreoretinal surgery was performed within one week after ultrasound examination. Two-dimensional ultrasound was used to observe the morphology of vitreous opacity, its connection to the eyeball wall, and whether posterior vitreous detachment and retinal detachment have occurred. CDFI examination was used to observe the presence of blood flow signals on the pathological membrane. The detection rates of different forms of vitreous opacity and traction retinal detachment were calculated. The location of proliferative lesions in the eye was analyzed. Paired t-test was performed to compare the AL of the affected eye and the healthy eye on the opposite side. Perform Kappa consistency test on the location of proliferative lesions was used during CDFI examination and vitreoretinal surgery. Results:All affected eyes have varying degrees of vitreous opacity. Among them, 23 eyes (37.7%, 23/61) showed typical "Christmas tree" like turbidity; 27 eyes (44.3%, 27/61) had clustered and striped echoes; 9 eyes (14.8%, 9/61) had weak punctate and strip echoes. Two eyes (3.3%, 2/61) showed a large amount of dense punctate and strip-shaped echoes. There were 50 eyes (82.0%, 50/61) with traction retinal detachment, of which 46 eyes (92.0%, 46/50) had visible blood flow signals on the detached retina, and the remaining 4 eyes (8.0%, 4/50) had no blood flow signals. During CDFI and surgery, there were 5 (8.2%, 5/61) and 4 (6.6%, 4/61) eyes with visible proliferative lesions in the periphery, respectively; 18 (29.5%, 18/61) and 14 (23.0%, 14/61) eyes were distributed in the posterior pole, respectively; there were 38 (62.3%, 38/61) and 43 (70.5%, 43/61) eyes with both peripheral and posterior polar regions, respectively. The consistency between CDFI and surgery in detecting the location of proliferative lesions was good ( κ=0.832, 95% confidence interval 0.691-0.973, P<0.001). The two-dimensional ultrasound measurement results showed that the AL of the affected eye was shorter than that of the contralateral healthy eye in 46 cases (75.4%, 46/61). Among the 52 patients who underwent AL biometry, the AL of the affected eye was shorter than that of the contralateral healthy eye by (0.63±0.68) mm, and the difference was statistically significant ( t=-6.738, P<0.05). Conclusions:CDFI can clearly display various intraocular lesions (vitreous opacity and traction retinal detachment) and eyeball sizes in children with OT. Vitreous opacity is often manifested as "Christmas tree" like, clustered, strip-shaped.
