Objective To investigate the predictive value of neutrophil to lymphocyte ratio (NLR) on admission for early neurological deterioration (END) in patients with lacunar stroke.Methods Patients with acute lacunar stroke admitted to the Department of Neurology,the Second People's Hospital of Lianyungang from June 2015 to October 2017 were enrolled retrospectively.END was defined as an increase of ≥2 in the National Institutes of Health Stroke Scale (NIHSS) score within 72 h of admission.Multivariate logistic regression analysis was used to determine the independent risk factors for END.The receiver operating characteristic (ROC) curve was used to analyze the predictive value of NLR for END in patients with lacunar stroke.Results A total of 309 patients with acute lacunar infarction were enrolled,including 180 males (58.2％),aged 59.7 ±7.3 years;65 patients (21.0％) in END group and 244 (79.0％) in non-END group.Multivariate logistic regression analysis showed that after adjusting for other confounders,NLR was an independent risk factor for END in lacunar stroke (odds ratio 4.508,95％ confidence interval 3.128-7.547;P＜0.001).ROC curve analysis showed that the area under the curve of NLR predicting END in patients with lacunar stroke was 0.725 (95％ confidence interval 0.671-0.776;P ＜ 0.001);the optimal cut-off value was 2.32,the sensitivity of predicting END was 61.21％,and the specificity was 72.54％.Conclusion The elevated NLR after admission is an independent risk factor for END in patients with lacunar stroke,which has certain value for early identification and prediction of END.

OBJECTIVE To explore the mechanism of action of Fushao Diqin Decoction in the treatment of colorectal cancer.METHODS In vitro cell experiments were conducted using Fushao Diqin Decoction to treat colorectal cancer CT-26 cells,and the cell proliferation and migration abilities were detected.Flow cytometry was used to detect the levels of reactive oxygen species(ROS)in colorectal cancer CT-26 cells,as well as the levels of iron ions(Fe2+),malondialdehyde(MDA),and the activity of su-peroxide dismutase(SOD).PCR Array and Western blot methods were used to analyze and verify the differential gene expression of ferroptosis.Balb/c mice were randomly divided into a blank control group,a model group,an oxaliplatin group(1.5 mg·kg-1·d-1),a low-dose group of Fushao Diqin Decoction(4.49 g·kg-1·d-1),a medium dose group of Fushao Diqin Decoction(8.97 g·kg-1·d-1),and a high-dose group of Fushao Diqin Decoction(17.94 g·kg-1·d-1)for in vivo animal experi-ments.The effects of Fushao Diqin Decoction on Fe2+,ROS,MDA levels,SOD activity,and Nrf2,Keap1,SLC7A11 and GPX4 ex-pression levels in mouse tumor tissues were tested.RESULTS In vitro cell experiments showed that compared with the blank control group,Fushao Diqin Decoction significantly inhibited the proliferation and migration of colorectal cancer CT-26 cells in a dose-de-pendent manner.Fushao Diqin Decoction could increase the Fe2+content(P＜0.05)and ROS level(P＜0.01)in colorectal cancer CT-26 cells,increase the MDA level in CT-26 cells of colorectal cancer(P＜0.01)and significantly reduce SOD activity(P＜0.01).Iron death PCR array analysis found that compared with the blank control group,after intervention with Fushao Diqin Decoc-tion,the expression of genes GPX4 and SLC7A11 was significantly downregulated,while the expression of GSTA1,HMOX1,Ca9,Chac1,Keap1,Sqstm1,NOX1,FTH1,Tfr1,SAT2,Pparg,and Hamp was significantly upregulated.Western blot analysis revealed that after intervention with Fushao Diqin Decoction,the expression of Keap1 protein was upregulated(P＜0.01),while the expression of Nrf2,SLC7A11,and GPX4 proteins was downregulated(P＜0.01)in colorectal cancer CT-26 cells.The results of in vivo animal experiments showed that Fushao Diqin Decoction significantly inhibited the growth of subcutaneous transplanted tumors in mice(P＜0.05),increased the degree of tumor tissue necrosis,and levels of Fe2+,ROS,and MDA(P＜0.05,P＜0.01),decreased SOD ac-tivity(P＜0.01)and upregulated Keap1 protein expression(P＜0.01),while downregulated Nrf2,SLC7A11,and GPX4 protein ex-pression(P＜0.01).CONCLUSION Fushao Diqin Decoction has an anti-colorectal cancer effect and may promote ferroptosis in colorectal cancer cells by inhibiting the Nrf2/SLC7A11/GPX4 signaling pathway to exert its anti-colorectal cancer effect.

ObjectiveTo explore the distribution of traditional Chinese medicine （TCM） syndromes of alopecia areata （AA）， and to provide reference for TCM clinical syndrome differentiation and classification of AA. MethodsAA patients who visited the specialized hairiness clinic of Beijing China-Japan Friendship Hospital were included. A questionnaire was developed including general information of the patients， history of hair loss （onset time， triggers and exacerbating factors， disease progression）， current symptoms （symptoms and signs）， medical history， personal history， family history， and hair microscopy examination results. The factor analysis and cluster analysis were used to determine the syndrome elements and to summarize the syndrome types. ResultsA total of 600 patients with AA were included， including 218 males （36.33%） and 382 females （63.67%）. Totally， 128 patients （21.33%） had a family history of hair loss， and 326 patients （54.33%） had a previous related underlying disease. The leading triggering and exacerbating factors of AA were tension and anxiety， accounting for 335 cases （55.83%） and 285 cases （47.50%）， respectively. The top 10 symptoms involved among patients were scalp oil， anxiety， irritability， dreaminess， fatigue， itching， tension， weakness and dandruff. The factor analysis showed that the factor rotation converged after 9 iterations， and finally obtained 12 common factors and 34 variables， with a cumulative contribution rate of 58.59%. In terms of disease location of AA， the main syndrome elements were liver， spleen and kidney， and the disease nature syndrome elements were mainly dampness-heat， qi stagnation， yin deficiency， qi deficiency， and blood deficiency. The clustering analysis of the 12 common factors showed that TCM syndromes could be summarized into four categories： internal retention of damp-heat， liver-kidney deficiency， qi and blood deficiency， and liver constraint and spleen deficiency. There were significant differences in the distribution of TCM syndromes in patients of different ages and genders （P＜0.001）. ConclusionThe main disease location of AA is in the liver， spleen， and kidney， with the liver being the key. The disease mechanism of AA is a deficiency-excess complex， initially manifested as excess and later becoming deficiency. The TCM syndromes mainly include four types which are internal retention of damp-heat， liver-kidney deficiency， qi and blood deficiency， and liver constraint and spleen deficiency.
