Objective:
To develop a model incorporating radiomic features and clinical factors to accurately predict acute ischemic stroke (AIS) outcomes.
Materials and Methods:
Data from 522 AIS patients (382 male [73.2%]; mean age ± standard deviation, 58.9 ± 11.5 years) were randomly divided into the training (n = 311) and validation cohorts (n = 211). According to the modified Rankin Scale (mRS) at 6 months after hospital discharge, prognosis was dichotomized into good (mRS ≤ 2) and poor (mRS > 2); 1310 radiomics features were extracted from diffusion-weighted imaging and apparent diffusion coefficient maps. The minimum redundancy maximum relevance algorithm and the least absolute shrinkage and selection operator logistic regression method were implemented to select the features and establish a radiomics model. Univariable and multivariable logistic regression analyses were performed to identify the clinical factors and construct a clinical model. Ultimately, a multivariable logistic regression analysis incorporating independent clinical factors and radiomics score was implemented to establish the final combined prediction model using a backward step-down selection procedure, and a clinical-radiomics nomogram was developed. The models were evaluated using calibration, receiver operating characteristic (ROC), and decision curve analyses.
Results:
Age, sex, stroke history, diabetes, baseline mRS, baseline National Institutes of Health Stroke Scale score, and radiomics score were independent predictors of AIS outcomes. The area under the ROC curve of the clinical-radiomics model was 0.868 (95% confidence interval, 0.825–0.910) in the training cohort and 0.890 (0.844–0.936) in the validation cohort, which was significantly larger than that of the clinical or radiomics models. The clinical radiomics nomogram was well calibrated (p > 0.05). The decision curve analysis indicated its clinical usefulness.
Conclusion
The clinical-radiomics model outperformed individual clinical or radiomics models and achieved satisfactory performance in predicting AIS outcomes.

To study the effect of different storage time on the chemical compositions and sulfur dioxide residues of sulfur-fumigated Gastrodiae Rhizoma (GR), and provide scientific basis for solving the quality and safety issues of sulfur-fumigated traditional Chinese medicinal materials. GR, sulfur-fumigated GR and its medicinal slices were stored under the same conditions, and then 8 active ingredients and sulfur dioxide residues were measured respectively. The results showed that the content of gastrodins in sulfur-fumigated GR and its medicinal slices was significantly lower than that in the non-fumigated GR. Moreover, the content of sulfur dioxide residue in sulfur-fumigated GR was significantly higher than that in its medicinal slices. That is to say, sulfur fumigation degree had significantly higher effect on GR quality as compared with its medicinal slices. During the whole storage time (8 months), the content of the eight chemical components in GR was not changed greatly in general. However, after the storage for 4 months, the content of 8 components and sulfur dioxide residues in all of GR samples were significantly changed. In particular, the content of sulfur dioxide residue in GR medicinal materials decreased up to 50% or more.

Studies on the characteristic chemical markers of sulfur fumigation have become an effective auxiliary way for quality control of traditional Chinese medicine. This study established a quantitative analysis method for the determination of -hydroxybenzyl hydrogen sulfite (-HS) in Gastrodiae Rhizoma (GR) based on UPLC-MS/MS. Then, 37 batches of GR were screened, and the results showed that 27 batches of them were sulfur-fumigated. Especially, the GR samples in Yunnan producing areas were sulfur-fumigated more seriously. Based on the stability of -HS after different storage time and heat treatment methods, it was found that the content of -HS was stable and reliable in the storage period of 8 months and under normal heat treatment (50, 60, 70, 80 °C) conditions. In conclusion, this study shows a high sensitivity, good selectivity and good stability of -HS, which can provide reference for the quality control and sulfur fumigation screening of GR.

OBJECTIVE:
To compare the clinical efficacy between moxibustion and acupuncture for knee osteoarthritis (KOA), and to observe the effect on serum tumor necrosis factor-α(TNF-α), interleukin-1β(IL-1β), superoxide dismutase (SOD) and malondialdehyde (MDA).
METHODS:
A total of 60 patients with KOA were randomized into a moxibustion group (30 cases, 2 cases dropped off) and an acupuncture group (30 cases, 2 cases dropped off). In the aucpuncture group, acupuncture was applied at Neixiyan (EX-LE 4), Dubi (ST 35), Heding (EX-LE 2), Xuehai (SP 10), Liangqiu (ST 34), Zusanli (ST 36) and point on the affected side for 30 min.In the moxibustion group, moxibustion was adopted at knee for 60 min. The treatment was given once every two days for 4 weeks, totally 14 times. Before and after treatment, the western ontario and McMaster universities osteoarthritis index (WOMAC) score was compared, and the therapeutic effect was evaluated in the two groups. The contents of serum TNF-αand IL-1β, the activity of serum SOD and the serum level of MDA were detected in the two groups.
RESULTS:
Compared before treatment, the WOMAC scores and the contents of serum TNF-α, IL-1β and MDA after treatment were reduced (<0.05), the activity of serum SOD was increased (<0.05) in the two groups. In the moxibustion group, the WOMAC score and the contents of serum TNF-α, IL-1β and MDA after treatment were lower than the acupuncture group (<0.05), the activity of serum SOD was higher than the acupuncture group (<0.05). The total effective rate was 89.3% (25/28) in the moxibustion group, which was superior to 42.9% (12/28) in the acupuncture group (<0.05).
CONCLUSION
Moxibustion and acupuncture can relieve KOA symptoms, and the therapeutic effect of moxibustion is superior to acupuncture. The mechanism may be related to the reduction of serum inflammatory factor and oxidative stress factor.

TRPA1 channels are non-selective cation channels that could be activated by plant-derived pungent products, including gingerol, a main active constituent of ginger. Ginger could improve the digestive function; however whether ginger improves the digestive function through activating TRPA1 receptor in gastrointestinal tract has not been investigated. In the present study, gingerol was used to stimulate cell lines (RIN14B or STC-1) while depletion of extracellular calcium. TRPA1 inhibitor (rethenium red) and TRPA1 gene silencing via TRPA1-specific siRNA were also used for mechanistic studies. The intracellular calcium and secretion of serotonin or cholecystokinin were measured by fura-2/AM and ELISA. Stimulation of those cells with gingerol increased intracellular calcium levels and the serotonin or cholecystokinin secretion. The gingerol-induced intracellular calcium increase and secretion (serotonin or cholecystokinin) release were completely blocked by ruthenium red, EGTA, and TRPA1-specific siRNA. In summary, our results suggested that gingerol derived from ginger might improve the digestive function through secretion releasing from endocrine cells of the gut by inducing TRPA1-mediated calcium influx.

Objective: To evaluate the efficacy and safety of fecal microbiota transplantation (FMT) in the treatment of autism spectrum disorder (ASD). Methods: A longitudinal study was conducted. Clinical data from ASD patients with gastrointestinal symptoms and who underwent FMT in the Tenth People's Hospital affiliated to Tongji University or Jinling Hospital between May 2012 to May 2021 were retrospectively collected. Scores derived from the autism behavior checklist (ABC), the childhood autism rating scale (CARS), the Bristol stool form scale (BSFS), and the gastrointestinal symptom rating scale (GSRS) were analyzed at baseline and at the 1st, 3rd, 6th, 12th, 24th, 36th, 48th and 60th month after FMT. Records of any adverse reactions were collected. Generalized estimating equations were used for analysis of data on time points before and after FMT. Results: A total of 328 patients met the inclusion criteria for this study. Their mean age was 6.1±3.4 years old. The cohort included 271 boys and 57 girls. The percentage of patients remaining in the study for post-treatment follow-up at the 1st, 3rd, 12th, 24th, 36th, 48th and 60th month were as follows: 303 (92.4%), 284 (86.7%), 213 (64.9%), 190 (57.9%), 143 (43.6%), 79 (24.1%), 46 (14.0%), 31 (9.5%). After FMT, the average ABC score was significantly improved in the first 36 months and remained improved at the 48th month. However, the average score was not significantly different from baseline by the 60th month (1st-36th month, P<0.001; 48th month, P=0.008; 60th month, P=0.108). The average CARS score improved significantly during the first 48 months and remained improved at the 60th month (1st-48th month, P<0.001; 60th month, P=0.010). The average BSFS score was also significantly improved in the first 36 months (with an accompanying stool morphology that resembled type 4). This improvement was maintained at the 48th month. However, the average score was similar to baseline at the 60th month (1st-36th month, P<0.001; 48th month, P=0.008; 60th month, P=0.109). The average GSRS score was significantly improved during the first 24 months, but not afterwards (1st-24th month, P<0.001; 36th month, P=0.209; 48th month, P=0.996; 60th month, P=0.668). The adverse events recorded during treatment included abdominal distension in 21 cases (6.4%), nausea in 14 cases (4.3%), vomiting in 9 cases (2.7%), abdominal pain in 15 cases (4.6%), diarrhea in 18 cases (5.5%), fever in 13 cases (4.0%), and excitement in 24 cases (7.3%). All adverse reactions were mild to moderate and improved immediately after suspension of FMT or on treatment of symptoms. No serious adverse reactions occurred. Conclusion: FMT has satisfactory long-term efficacy and safety for the treatment of ASD with gastrointestinal symptoms.
