OBJECTIVE: To evaluate the dynamic changes of glucocorticoid (GC) dose and the feasibility of GC discontinuation in rheumatoid arthritis (RA) patients under the background of Chinese medicine (CM). METHODS: This multicenter retrospective cohort study included 1,196 RA patients enrolled in the China Rheumatoid Arthritis Registry of Patients with Chinese Medicine (CERTAIN) from September 1, 2019 to December 4, 2023, who initiated GC therapy. Participants were divided into the Western medicine (WM) and integrative medicine (IM, combination of CM and WM) groups based on medication regimen. Follow-up was performed at least every 3 months to assess dynamic changes in GC dose. Changes in GC dose were analyzed by generalized estimator equation, the probability of GC discontinuation was assessed using Kaplan-Meier curve, and predictors of GC discontinuation were analyzed by Cox regression. Patients with <12 months of follow-up were excluded for the sensitivity analysis. RESULTS: Among 1,196 patients (85.4% female; median age 56.4 years), 880 (73.6%) received IM. Over a median 12-month follow-up, 34.3% (410 cases) discontinued GC, with significantly higher rates in the IM group (40.8% vs. 16.1% in WM; P<0.05). GC dose declined progressively, with IM patients demonstrating faster reductions (median 3.75 mg vs. 5.00 mg in WM at 12 months; P<0.05). Multivariate Cox analysis identified age <60 years [P<0.001, hazard ratios (HR)=2.142, 95% confidence interval (CI): 1.523-3.012], IM therapy (P=0.001, HR=2.175, 95% CI: 1.369-3.456), baseline GC dose ⩽7.5 mg (P=0.003, HR=1.637, 95% CI: 1.177-2.275), and absence of non-steroidal anti-inflammatory drugs use (P=0.001, HR=2.546, 95% CI: 1.432-4.527) as significant predictors of GC discontinuation. Sensitivity analysis (545 cases) confirmed these findings. CONCLUSIONS RA patients receiving CM face difficulties in following guideline-recommended GC discontinuation protocols. IM can promote GC discontinuation and is a promising strategy to reduce GC dependency in RA management. (Trial registration: ClinicalTrials.gov, No. NCT05219214).

OBJECTIVE: To explore the efficacy and survival of venetoclax based (VEN-based) regimen in the treatment of acute myeloid leukemia（AML）. METHODS: A retrospective study was conducted in patients who received VEN-based regimen and completed at least 1 course of efficacy evaluation at the The First Affiliated Hospital of Nanchang University from July 2019 to July 2022. The incidence of complete remission （CR）/CR with incomplete hematologic recovery （CRi） rate, objective remission rate（ORR） and survival of patients with different risk strati- fication and gene subtypes were analyzed. RESULTS: A total of 79 patients were enrolled, including 43 patients with newly diagnosed unfit AML （unfit AML） and 36 relapsed/refractory AML (R/R AML). The median age of the patients was 62(14-83) years old. 36 out of 79 patients achieved CR/CRi and the ORR of the whole cohort was 64.6%. The CR/CRi rate of unfit AML patients was significantly higher than that of R/R AML patients (60.5% vs 27.8%, P=0.004). In unfit AML cohort, the patients with NPM1 and IDH1/2 mutations were benefited, 8 out of 9 patients ahcieved CR/CRi, 7/8 and 5/8 patients achieved minimal residual disease (MRD) negativity, respectively. Six out of 9 patients with TET2 mutation achieved CR/CRi, 3/6 patients achieved MRD negativity. In R/R AML cohort, 2 out of 3 patients with RUNX1 mutation achieved CR/CRi, without MRD negative, while the CR/CRi rate of patients with other gene mutations was lower than 40%. The median follow-up time was 10.1(95%CI: 8.6-11.6) months. In whole cohort, the median overall survival (mOS) time was 9.1 months and the relapse free survival (RFS) time was not reached. The mOS and RFS of unfit AML patients were significantly longer than those of R/R AML patients (14.1 vs 6.8 months, P=0.013; not reached vs 3.3 months, P=0.000). In unfit AML cohort, the mOS of patients with NPM1 or IDH1/2 mutations was not reached, while that of patients without NPM1 or IDH1/2 mutations was 8.0 months (P=0.009; P=0.022). Furthermore, the mOS of patients with TP53 mutaion was significantly shorter than that of patients without TP53 mutation (5.2 vs 14.1 months， P=0.049). In R/R AML cohort, there was no significant difference in mOS between patients with mutation in each gene subtype and those without gene mutation (P>0.05). All patients had hematology adverse reactions, 91.1% patients had AE grade≥3. The most common non-hematology adverse reactions was infection, with an incidence of 91.1%. VEN-based regimen was tolerable for AML patients. CONCLUSION VEN-based regimen can achieve a high response rate, especially in unfit AML with acceptable safety, and some patients can achieve MRD negative. It is also effective in NPM1-, IDH1/2-positive patients with long survival time.

Objective: To explore the feasibility of applying quantitative analysis of the facial skin color to evaluate the severity of motion sickness objectively and to seek objective indicators that can reflect the severity of motion sickness. Methods: Motion sickness was induced in 51 male adult subjects recruited at the Air Force Medical University by Coriolis acceleration stimulation, and facial skin colorimetric values were acquired using a portable spectrophotometer at five time points: before stimulation and at 0 min, 10 min, 20 min and 30 min after the end of stimulation. The Graybiel rating scales were applied to assess the severity of motion sickness in subjects at each time point after stimulation, and the correlation between the magnitude of change in each colorimetric value and the maximum Graybiel's score was analyzed. The ROC curves were used to compare the evaluation performance of colorimetric value indicators which could reflect the severity of motion sickness. Results: Each colorimetric value in the CIE-L^*a^*b^* color system changed significantly after exposure to provocative motion stimuli, and the trend was consistent with the typical sign of pallor in motion sickness. The magnitudes of the increase in the colorimetric value CIE-L^*, the decrease in CIE-a^*, and the increase in CIE-b^* were all significantly and positively correlated with the maximum of Graybiel's scores (r=0.490 0, P=0.000 3; r=0.549 3, P<0.000 1; r=0.540 9, P<0.000 1). Comparing the performance of three colorimetric indicators to assess the severity of motion sickness, CIE-a^* had an area under the ROC curve of 0.875 0, a sensitivity of 85.71%, and a specificity of 87.50%, which was better than CIE-L^* and CIE-b^*. Conclusions: The CIE-L^*a^*b^* colorimeter values can be considered as objective indicators of the severity of motion sickness, among which the colorimetric indicator CIE-a^* has the most diagnostic significance, and the method of quantitative analysis of the facial skin color can provide a new reference for the objective evaluation of the severity of motion sickness.

This article aims to investigate the ameliorative effect of Linderae Radix ethanol extract on hyperlipidemia rats induced by high-fat diet and to explore its possible mechanism from the perspective of reverse cholesterol transport(RCT). SD rats were divided into normal group, model group, atorvastatin group, Linderae Radix ethanol extract(LREE) of high, medium, low dose groups. Except for the normal group, the other groups were fed with a high-fat diet to establish hyperlipidemia rat models; the normal group and the model group were given pure water, while each administration group was given corresponding drugs by gavage once a day for five weeks. Serum total cholesterol(TC), triglyceride(TG), high density lipoprotein-cholesterol(HDL-c), low density lipoprotein-cholesterol(LDL-c), alanine aminotransferase(ALT), and aspartate aminotransferase(AST) levels were measured by automatic blood biochemistry analyzer; the contents of TC, TG, total bile acid(TBA) in liver and TC and TBA in feces of rats were detected by enzyme colorimetry. HE staining was used to observe the liver tissue lesions; immunohistochemistry was used to detect the expression of ATP-binding cassette G8(ABCG8) in small intestine; Western blot and immunohistochemistry were used to detect the expression of peroxisome proliferator-activated receptor gamma/aerfa(PPARγ/α), liver X receptor-α(LXRα), ATP-binding cassette A1(ABCA1) pathway protein and scavenger receptor class B type Ⅰ(SR-BⅠ) in liver. The results showed that LREE could effectively reduce serum and liver TC, TG levels, serum LDL-c levels and AST activity, and increase HDL-c levels, but did not significant improve ALT activity and liver index; HE staining results showed that LREE could reduce liver lipid deposition and inflammatory cell infiltration. In addition, LREE also increased the contents of fecal TC and TBA, and up-regulated the protein expressions of ABCG8 in small intestine and PPARγ/α, SR-BⅠ, LXRα, and ABCA1 in liver. LREE served as a positive role on hyperlipidemia model rats induced by high-fat diet, which might be related to the regulation of RCT, the promotion of the conversion of cholesterol to the liver and bile acids, and the intestinal excretion of cholesterol and bile acids. RCT regulation might be a potential mechanism of LREE against hyperlipidemia.

Abstract： Objective To analyze the first epidemic spread of the novel coronavirus Delta variant in China based on public security forensic perspective, investigate its transmission characteristics, contributing factors, and epidemiologic research experience, and provide a reference for the prevention and control of the epidemic caused by the novel coronavirus variant. Methods Based on the information that public security forensic experts obtained from front-line epidemiologic research, the gender, age, place of residence, transmission route and infectivity of the coronavirus disease 2019 （COVID-19） confirmed cases, asymptomatic infected persons and their close contacts in Guangzhou caused by the novel coronavirus Delta variant were analyzed. The basic reproduction number （R₀） during this epidemic in Guangzhou was calculated. Results Among the 153 cases infected with novel coronavirus Delta variant in the epidemic, 63 cases were male and 90 cases were female, their age ranging from 1 to 92 years, with a median age of 49 years. The main route of transmission was close contact, including dining together, co-living, and close contact in the same residential building. There were 31 cases of family clusters, 25 of which were in Liwan District. The epidemic lasted from May 26 to May 29, and the R₀ remained above 4.0. After May 30, R₀ began to decline and remained below 1.0 from June 7. Conclusion The novel coronavirus Delta variant is highly infectious, the crowd is generally susceptible to infection and family cluster cases are easy to occur. So, it is necessary to precisely prevent and control this strain. Public security forensic experts have both medical literacy and criminal investigation capabilities, they can play a more professional role in epidemic prevention and control.

OBJECTIVE: To investigate the related factors of adverse reactions of blood transfusion, and clinical precautions so as to reduce the adverse reactions. METHODS: Data of 2108 patients with allogeneic transfusion in our hospital from January 2017 to June 2017 collected and analyzed. RESULTS: These patients received 15 244 time of blood transfusion, and 213 time of adverse reactions occurred in 178 patients in totality, the incidence is 1.4%, and there was no significant difference between the male (1.31%) and female (1.53%). The main type of transfusion reaction were allergy (73.23%), FNHTR (11.74%) and TACO (10.80%). Among all kinds of blood components, the incidence of adverse reactions of apheresis platelet transfusion was the highest (4.31%), significantly higher than that of cryoprecipitate and other blood components. The incidence rate of adverse reactions of blood transfusion in the hematopathy patients was 2.56%, significantly higher than that of immune diseases (1.48%), cancer diseases (1.28%) and other diseases (1.08%), (P＜0.01). The rate of transfusion history of apheresis platelets was 42.67% (the incidence of adverse reactions was 4.31%), significantly higher than other groups (P＜0.01); the rate of transfusion history of cryoprecipitate was 4.11% (the incidence of adverse reaction was 0.45%), significantly lower than other groups (P＜0.05). Among the disease types, the rate of transfusion history in the hematopathy patients was 48.79% (the incidence of adverse reaction was 2.56%), significantly higher than that of other groups (P＜0.01). The incidence of drug allergy in patients with the adverse reactions to blood transfusion was 11.25%, significantly higher than that of patients without adverse reactions (4.71%) (P＜0.01). CONCLUSION The main risk factors of adverse reactions of blood transfusion are as follows: blood varieties, disease type, transfusion history and drug allergy history. For the patients with transfusion, multiple factors should be controlled, so as to reduce the adverse reactions.

Coicis Semen is widely used as a raw material which can be used as both medicine and food among people. According to the ancient monographs on materia medica and relevant documents on the processing specifications in various provinces and cities, herba logical study on the historical evolution of the processing methods of Coicis Semen was conducted in this paper from the aspects of collecting and processing methods of Coicis Semen, the processing methods in the past dynasties and the nature, flavour and efficacy of Coicis Semen. The results showed that the processing methods of Coicis Semen recorded in monographs on materia medica mainly included stir-frying, glutinous rice stir-frying, salt processing(including salt cooking and salt stir-frying), stir-frying with the earth scraped from the wall facing east, and ginger juice stir-frying, etc. Among them, stir-frying, and stir-frying with the earth scraped from the wall facing east are still used nowadays. The bran stir-frying is the improved version of glutinous rice stir-frying in order to be adaptive to the modern-day situation and the needs of the present. In addition, the ancient shell removal and kernel keeping method are also included in the processing procedures in modern local processing specifications, which are combined with frying to form a new method named "Fazhi" processing( "Fazhi" means a processing method of multiple procedures). The 2015 edition of Chinese Pharmacopoeia records that Coicis Semen is helpful to clear dampness and promote diuresis, strengthen the spleen and prevent diarrhea, eliminate impediment, discharge pus, resolve toxin and a mass, etc., which are consistent with those contained in ancient monographs on materia medica. After the "Fazhi" processing, the cold nature of Coicis Semen has been removed and its nature,flavour and meridian tropism have been changed, so its application scopes expanded. The results of this study clearly traced the history of the collecting and proces-sing of Coicis Semen, summarized the nature, flavour and efficacy of Coicis Semen contained in both ancient and modern literature, and provided a historical basis for the standardization of the subsequent processing technology of Coicis Semen, the clinical application of various processed products, and the further development and utilization of medicinal materials.
