Objective:To advance the understanding of posterior reversible encephalopathy syndrome (PRES) after allogeneic hematopoietic stem cell transplantation (allo-HSCT).Methods:The medical history, diagnosis and treatment process, laboratory examination and imaging examination results of a patient who developed PRES after undergoing allo-HSCT at Changhai Hospital of Naval Medical University in November 2022 were retrospectively analyzed, and the relevant literature was reviewed.Results:The patient was a 33-year-old woman, and she was admitted to the hospital with 17 years of diagnosis of aplastic anemia, 1 month after sibling-matched allo-HSCT, with low-grade fever for 1 week. On the 7th day of hospitalization, the patient experienced a sudden onset of seizures. After combining findings from cranial magnetic resonance imaging (MRI) and other relevant examinations, organic brain lesions were ruled out, and PRES was considered. The patient's condition improved after receiving antihypertensive, antiepileptic, anti-infection, and other appropriate treatments. A follow-up cranial enhanced MRI was performed 3 months after the onset of symptoms revealed the disappearance of lesions.Conclusions:PRES after allo-HSCT has the potential to yield favorable outcomes when it is promptly diagnosed and treated.

This paper introduced the overview of the "eight trends" of Chinese medicinal materials(CMM) industry in 2021, analyzed the problems of CMM production, and put forward development suggestions. Specifically, "eight trends" could be summarized as follows.(1) The growing area of CMM tended to be stable, and some provinces began to release the local catalog of Dao-di herbs.(2) The protection process of new varieties accelerated, and a number of excellent varieties were bred.(3) The theory of ecological cultivation was further enriched, and the demonstration effect of ecological cultivation technology was prominent.(4) Some CMM realized complete mechanization and formed typical model cases.(5) The number of cultivation bases using the traceability platform increased, and provincial internet trading platforms were set up.(6) The construction of CMM industrial clusters accelerated, and the number of provincial-level regional brands increased rapidly.(7) Many new agricultural business entities were founded nationwide, and a variety of methods were used to drive the intensified development of CMM.(8) A number of local TCM laws were promulgated, and the management regulation of food and medicine homology substances catalogs was issued. On this basis, four suggestions for CMM production were proposed.(1) It is suggested to speed up the formulation of the national catalog of Dao-di herbs and carry out the certification of Dao-di herbs production bases.(2) Ecological planting of forest and grassland medicine should be further strengthened in terms of technical research and promotion based on the principle of ecological priority.(3) The basic work of disaster prevention should be paid more attention and technical measures for disaster mitigation should be developed.(4) The planted area of commonly used CMM should be incorporated into the national regular statistical system.

BACKGROUND: The presence of fibrosis is a criterion for subtype classification in the newly updated hypersensitivity pneumonitis (HP) guidelines. The present study aimed to summarize differences in clinical characteristics and prognosis of non-fibrotic hypersensitivity pneumonitis (NFHP) and fibrotic hypersensitivity pneumonitis (FHP) and explore factors associated with the presence of fibrosis. METHODS: In this prospective cohort study, patients diagnosed with HP through a multidisciplinary discussion were enrolled. Collected data included demographic and clinical characteristics, laboratory findings, and radiologic and histopathological features. Logistic regression analyses were performed to explore factors related to the presence of fibrosis. RESULTS: A total of 202 patients with HP were enrolled, including 87 (43.1%) NFHP patients and 115 (56.9%) FHP patients. Patients with FHP were older and more frequently presented with dyspnea, crackles, and digital clubbing than patients with NFHP. Serum levels of carcinoembryonic antigen, carbohydrate antigen 125, carbohydrate antigen 153, gastrin-releasing peptide precursor, squamous cell carcinoma antigen, and antigen cytokeratin 21-1, and count of bronchoalveolar lavage (BAL) eosinophils were higher in the FHP group than in the NFHP group. BAL lymphocytosis was present in both groups, but less pronounced in the FHP group. Multivariable regression analyses revealed that older age, <20% of lymphocyte in BAL, and ≥1.75% of eosinophil in BAL were risk factors for the development of FHP. Twelve patients developed adverse outcomes, with a median survival time of 12.5 months, all of whom had FHP. CONCLUSIONS Older age, <20% of lymphocyte in BAL, and ≥1.75% of eosinophil in BAL were risk factors associated with the development of FHP. Prognosis of patients with NFHP was better than that of patients with FHP. These results may provide insights into the mechanisms of fibrosis in HP.

AIM: To evaluate the applicability of Chinese dry eye questionnaire in college students using the ocular surface disease index(OSDI)questionnaire as a reference.METHODS: Cross-sectional study. A total of 711 college students from Nanyang Medical College were enrolled in the study and assessed for dry eye condition using OSDI questionnaire and Chinese dry eye questionnaire. The response rate of each question in the two questionnaires was counted. Cronbach α was calculated to evaluate the internal consistency of both questionnaires. Correlation between the total scores of the two questionnaires was analyzed to evaluate the criterion validity. Based on OSDI scores, the discriminant validity of Chinese dry eye questionnaire was evaluated; receiver operating characteristic(ROC)curves was plotted for Chinese dry eye questionnaire scores, area under the ROC curve(AUC)was calculated, and diagnostic thresholds and corresponding sensitivity and specificity were also analyzed.RESULT: The response rates of the 12 questions on the OSDI questionnaire were 33.2%-100.0%, while it was 100.0% for each question on the Chinese dry eye questionnaire. The Cronbach α values of OSDI questionnaire and Chinese dry eye questionnaire were 0.905 and 0.789, respectively. The Chinese dry eye questionnaire score was positively correlated with the OSDI score(rs=0.712, P<0.001). According to OSDI questionnaire scores, dry eye severity was divided into normal group, mild dry eye group, moderate dry eye group and severe dry eye group. The scores of Chinese dry eye questionnaire in these groups were 4.00(2.00, 6.00), 9.00(7.00, 11.00), 12.00(9.00, 14.00)and 16.00(13.50, 22.00), respectively, which increased with the severity of dry eye, and the overall difference was statistically significant(P<0.001), as well as pairwise comparison between groups(P<0.05). The AUCs of Chinese dry eye questionnaire in distinguishing normal population from dry eye population, mild dry eye from moderate dry eye, moderate dry eye from severe dry eye were 0.862, 0.661 and 0.769, respectively, and the diagnostic thresholds were 6.5, 11.5 and 14.5, respectively.CONCLUSION:Chinese dry eye questionnaire has an equivalent reliability, validity, discriminant ability and better response rate for dry eye screening and epidemiological survey among college students in China compared with OSDI questionnaire.

This work aimed to investigate the differences of pharmacokinetics and tissue distribution of four alkaloids in Ermiao Pills and Sanmiao Pills in normal and arthritic model rats. The rat model of arthritis was established by injecting Freund's complete adjuvant, and ultra-high performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS) in the positive ion multiple reaction monitoring(MRM) mode was used for the determination of four alkaloids in plasma and tissues of normal and arthritic rats after administration of Ermiao Pills and Sanmiao Pills, respectively. The differences in pharmacokinetics and tissue distribution of the four active components were compared, and the effect of Achyranthis Bidentatae Radix on the major components of Sanmiao Pills was explored. This study established an UPLC-MS/MS for simultaneous determination of four alkaloids, and the specificity, linearity, accuracy, precision, and stability of this method all met the requirements. Pharmacokinetics study found that as compared with normal rats, the AUC and C_(max) of phellodendrine, magnoflorine, berberine and palmatine in model rats were significantly decreased after administration of Ermiao Pills, the clearance rate CL/F was significantly increased, and the distribution and tissue/plasma concentration ratio of the four alkaloids in the liver, kidney, and joint were significantly reduced. Achyranthis Bidentatae Radix increased the AUC of phellodendrine, berberine, and palmatine, reduced the clearance rate, and significantly increased the distribution of the four alkaloids in the liver, kidney, and joints in arthritic rats. However, it had no significant effect on the pharmacokinetics and tissue distribution of the four alkaloids in normal rats. These results suggest that Achyranthis Bidentatae Radix may play a guiding role in meridian through increasing the tissue distribution of effective components in Sanmiao Pills under arthritis states.

BACKGROUND: Shenyankangfu Tablet (SYKFT) is a Chinese patent medicine that has been used widely to decrease proteinuria and the progression of chronic kidney disease. OBJECTIVE: This trial compared the efficacy and safety of SYKFT, for the control of proteinuria in primary glomerulonephritis patients, against the standard drug, losartan potassium. DESIGN, SETTING, PARTICIPANTS AND INTERVENTION: This was a multicenter, double-blind, randomized, controlled clinical trial. Primary glomerulonephritis patients, aged 18-70 years, with blood pressure ≤ 140/90 mmHg, estimated glomerular filtration rate (eGFR) ≥ 45 mL/min per 1.73 m MAIN OUTCOME MEASURES: The primary outcome was change in the 24-hour proteinuria level, after 48 weeks of treatment. RESULTS: A total of 735 participants were enrolled. The percent decline of urine protein quantification in the SYKFT group after 48 weeks was 8.78% ± 2.56% (P = 0.006) more than that in the losartan 50 mg group, which was 0.51% ± 2.54% (P = 1.000) less than that in the losartan 100 mg group. Compared with the losartan potassium 50 mg group, the SYKFT plus losartan potassium 50 mg group had a 13.39% ± 2.49% (P < 0.001) greater reduction in urine protein level. Compared with the losartan potassium 100 mg group, the SYKFT plus losartan potassium 100 mg group had a 9.77% ± 2.52% (P = 0.001) greater reduction in urine protein. With a superiority threshold of 15%, neither was statistically significant. eGFR, serum creatinine and serum albumin from the baseline did not change statistically significant. The average change in TCM syndrome score between the patients who took SYKFT (-3.00 [-6.00, -2.00]) and who did not take SYKFT (-2.00 [-5.00, 0]) was statistically significant (P = 0.003). No obvious adverse reactions were observed in any group. CONCLUSION: SYKFT decreased the proteinuria and improved the TCM syndrome scores of primary glomerulonephritis patients, with no change in the rate of decrease in the eGFR. SYKFT plus losartan potassium therapy decreased proteinuria more than losartan potassium therapy alone. TRIAL REGISTRATION NUMBER NCT02063100 on ClinicalTrials.gov.

Objective:To study the association between metabolic syndrome （MS） and Chinese healthy eating index （CHEI）， and to identify the beneficial or adverse effects of diets on MS in a community population of Shanghai. Methods:Based on the inclusion and exclusion criteria， the data of 4 856 subjects from a community in Shanghai was collected by interview. Total CHEI score and its component score were calculated based on the frequency of food consumption. Physical examination and blood biochemical tests were used to diagnose MS. The logistic regression model was used to analyze the relationship between MS or relative indexes and the total CHEI score or its component score. Results:The study showed the overall prevalence of MS was 24.71%. There were significant differences between MS group and controls （P<0.05） in age， BMI， waist circumference， fasting blood glucose， triglycerides， total cholesterol， systolic blood pressure， diastolic blood pressure， glycated hemoglobin， high-density lipoprotein and energy intake. After adjusting for potential confounders， it showed that the higher total CHEI score， the lower risk of central obesity， increased diastolic blood pressure， increased glycated hemoglobin， hyperglycemic and MS （P<0.05）. The increase in component score of potatoes， milk， beans， dark vegetables， fruits， oil and sodium reduced risk of obesity， hypertension， hyperglycemia， dyslipidemia and MS （P<0.05）. Conclusion:The quality of healthy diet （CHEI score more than 80） and increased intake of specific dietary components （potatoes， milk， beans， dark vegetables， fruits） reduce the risk of MS effectively.
