The statement of heavy dampness leading to watery diarrhea was recorded in Huang Di Nei Jing(The Yellow Emperor's Inner Classic),which is not only an interpretation of the pathogenesis of diarrhea,but also one of the important principles to guide the clinical treatment of diarrhea in traditional Chinese medicine.The watery diarrhea can be caused by the invasion of external dampness,or results from the retention and accumulation of internal dampness.The combination of internal dampness and external dampness causes internal injury of spleen yang,and then the spleen yang is inactivated,which eventually results in diarrhea.Based on the pathogenesis of spleen yang inactivation and water-dampness retention and accumulation in heavy dampness leading to watery diarrhea,the therapeutic principle of warming and activating spleen yang should be performed.Modern Chinese medicine clinical practice and related mechanism research showed that the therapy of warming and activating spleen yang was closely related to the mitochondrial function in modern western medicine.The mechanism Linggui Zhugan Decoction and Fuzi Lizhong Decoction in relieving watery diarrhea by warming and activating spleen yang is related to the improvement of the energy metabolism disorder in the mitochondrion;the mechanism of Shengyang Yiwei Decoction and Shengyang Chushi Decoction in relieving watery diarrhea by raising yang and eliminating dampness is related to the improvement of mitochondrial damage in the inflammatory state;the mechanism of Xiao Jianzhong Decoction and Lizhong Decoction in relieving watery diarrhea by activating spleen is related to the improvement of mitochondrial oxidative damage.The exploration of the pathogenesis of heavy dampness leading to watery diarrhea and the modern mechanism of therapy of warming and activating spleen yang will provide reference for the study of the etiology and pathogenesis of pathogenic dampness and the dampness syndrome,and can provide reference for the prevention and treatment of diarrhea patients in the humid climate environment such as in Lingnan area and the middle and lower reaches of the Yangtze River and under the combined influence of improper dietary structure in modern society.

Abstract: Objective To investigate a poisoning incident caused by eating eight treasure congee, and establish liquid chromatography (LC)-mass spectrometry (MS)/MS screening method of 28 alkaloids to provide references for disposal of similar poisoning incidents. Methods LC-MS/MS was used for screening 28 alkaloids in the urine, eight treasure congee and food raw material, and the detected alkaloids were quantified. Samples were extracted with 0.4% formic acid aqueous solution and separated by a Acquity UPLC BEH C18 column (1.7 μm, 100 × 2.1 mm). Acetonitrile-0.2% formic acid aqueous solution was used as the mobile phase and gradient elution was adopted. The ionization mode was electrospray positive ionization mode, and the detection method was multi-reaction monitoring (MRM). Analytes were quantified with the external standard method. Results In the concentration range of 0-100 ng/mL, the linear correlation coefficient r were greater than 0.999 for 28 alkaloids. The recovery of 28 alkaloids in urine sample ranged from 63.0% to 105.0%, and the relative standard deviations (RSDs) were between 5.8% and 8.6%. The recovery of 28 alkaloids in eight treasure congee sample ranged from 72.0% to 109.0%, and the RSDs were between 6.3% and 9.7%. The recovery of 28 alkaloids in semen sesami nigrum sample ranged from 60.0% to 95.0%, and the RSDs were between 4.8% and 8.2%. Hyoscyamine (2 380.0 ng/mL), scopliamine (3.6 ng/mL) and rac-anisodamine (4.7 ng/mL) were detected in the patient's urine. Hyoscyamine (63.3 μg/g), scopliamine (5.7 μg/g) and rac-anisodamine (2.1 μg/g) were detected in eight treasure congee. Hyoscyamine (901.0 μg/g), scopliamine (80.0 μg/g) and rac-anisodamine (30.1 μg/g) were detected in the seed of Datura stramonium L. The ratio of scopliamine and hyoscyamine in the seed of D. stramonium was 1∶11, which complies with the characteristics of D. stramonium L. In urine sample, the proportion of scopliamine and rac-anisodamine was 0.15% and 0.20%, and hyoscyamine accounted for 99.65%. Conclusion Seed morphology, the content range and proportion of three alkaloids are all in accord with the characteristics of D. stramonium. Combined with the clinical symptoms of atropine poisoning, it can be deduced that this incident is a family food poisoning caused by accidental consumption of seed of D. stramonium L. The method can provide technical support for the clinical diagnosis and treatment of alkaloid poisoning patients, and also provide a basis for emergency detection and disposal of alkaloid poisoning events.

OBJECTIVES:
To study the efficacy and safety of repeated application of rituximab (RTX) at a low dose (200 mg/m2) versus the recommended dose (375 mg/m2) for remission maintenance in frequently relapsing nephrotic syndrome (FRNS) or steroid-dependent nephrotic syndrome (SDNS).
METHODS:
A randomized controlled trial was conducted for 29 children with FRNS/SDNS who received systemic treatment in the Department of Nephrology, Anhui Provincial Children's Hospital, from September 2020 to December 2021. These children were divided into a recommended dose group (n=14) and a low dose group (n=15) using a random number table. The two groups were compared in terms of general characteristics, changes in CD19 expression after RTX treatment, number of relapses, glucocorticoid dose, adverse reactions of RTX, and hospital costs.
RESULTS:
After RTX treatment, both the low dose group and the recommended dose group achieved B-lymphocyte depletion and had significant reductions in the number of relapses and glucocorticoid dose (P<0.05). The low dose group had a comparable clinical effect to the recommended dose group after RTX treatment (P>0.05), and the low dose group had a significant reduction in hospital costs for the second, third, and fourth times of hospitalization (P<0.05). There were no serious adverse reactions in either group during RTX treatment and late follow-up, and there was no significant difference in adverse reactions between the two groups (P>0.05).
CONCLUSIONS
Repeated RTX treatment at a low dose has comparable clinical efficacy and safety to that at the recommended dose and can significantly reduce the number of FRNS/SDNS relapses and the amount of glucocorticoids used, with little adverse effect throughout the treatment cycle. Therefore, it holds promise for clinical application.

Objective: To understand the current status of diagnosis and treatment of chronic lymphocytic leukemia (CLL) /small lymphocytic lymphoma (SLL) among hematologists, oncologists, and lymphoma physicians from hospitals of different levels in China. Methods: This multicenter questionnaire survey was conducted from March 2021 to July 2021 and included 1,000 eligible physicians. A combination of face-to-face interviews and online questionnaire surveys was used. A standardized questionnaire regarding the composition of patients treated for CLL/SLL, disease diagnosis and prognosis evaluation, concomitant diseases, organ function evaluation, treatment selection, and Bruton tyrosine kinase (BTK) inhibitor was used. Results: ①The interviewed physicians stated that the proportion of male patients treated for CLL/SLL is higher than that of females, and the age is mainly concentrated in 61-70 years old. ②Most of the interviewed physicians conducted tests, such as bone marrow biopsies and immunohistochemistry, for patient diagnosis, in addition to the blood test. ③Only 13.7% of the interviewed physicians fully grasped the initial treatment indications recommended by the existing guidelines. ④In terms of cognition of high-risk prognostic factors, physicians' knowledge of unmutated immunoglobulin heavy-chain variable and 11q- is far inferior to that of TP53 mutation and complex karyotype, which are two high-risk prognostic factors, and only 17.1% of the interviewed physicians fully mastered CLL International Prognostic Index scoring system. ⑤Among the first-line treatment strategy, BTK inhibitors are used for different types of patients, and physicians have formed a certain understanding that BTK inhibitors should be preferentially used in patients with high-risk factors and elderly patients, but the actual use of BTK inhibitors in different types of patients is not high (31.6%-46.0%). ⑥BTK inhibitors at a reduced dose in actual clinical treatment were used by 69.0% of the physicians, and 66.8% of the physicians had interrupted the BTK inhibitor for >12 days in actual clinical treatment. The use of BTK inhibitors is reduced or interrupted mainly because of adverse reactions, such as atrial fibrillation, severe bone marrow suppression, hemorrhage, and pulmonary infection, as well as patients' payment capacity and effective disease progression control. ⑦Some differences were found in the perceptions and behaviors of hematologists and oncologists regarding the prognostic assessment of CLL/SLL, the choice of treatment options, the clinical use of BTK inhibitors, etc. Conclusion: At present, a gap remains between the diagnosis and treatment of CLL/SLL among Chinese physicians compared with the recommendations in the guidelines regarding the diagnostic criteria, treatment indications, prognosis assessment, accompanying disease assessment, treatment strategy selection, and rational BTK inhibitor use, especially the proportion of dose reduction or BTK inhibitor discontinuation due to high adverse events.

Objective:To investigate the birth weight (BW) of infants born to pregnant women living with human immunodeficiency virus (HIV) and its associated factors, and to provide more evidence for the prevention of mother-to-child transmission (PMTCT) in China.Methods:This study was a retrospective cohort study. Between January 2004 and December 2021, pregnant women living with HIV and their infants in Hubei Province were recruited and followed up, and clinical data were collected through hospital medical records and HIV/acquired immunodeficiency syndrome comprehensive response information management system. The multivariable linear regression was performed on the collected data to investigate associated influencing factors of BW.Results:In total, 531 pregnant women living with HIV (581 pregnancies) and 581 infants were enrolled. Of the 581 infants, 36 were HIV-positive, with a PMTCT rate of 6.2%. The mean BW of the infants was (3 075.0±470.2) gram. Protease inhibitor (PI) based-anti-retroviral therapy (ART) ( β=-0.1, 95% confidence interval ( CI)-188.2 to -37.1, P=0.004), ART in the first trimester( β=-0.1, 95% CI -201.9 to -65.5, P<0.001), infant HIV infection ( β=-0.1, 95% CI -310.4 to -68.2, P=0.002), hepatitis C virus infection ( β=0.1, 95% CI 71.2 to 410.4, P=0.005) and gestational age ( β=0.6, 95% CI 155.9 to 191.5, P<0.001) were associated with decreased BW. Conclusions:While improving the effectiveness of PMTCT for HIV, more attention should be paid to pregnant women who received ART in the first trimester and PI-based ART for preventing lower BW and improving maternal and infantile health.

The purpose of this study was to explore the effect and mechanism of dihydromyricetin (DHM) on Parkinson's disease (PD)-like lesions in type 2 diabetes mellitus (T2DM) rats. The T2DM model was established by feeding Sprague Dawley (SD) rats with high-fat diet and intraperitoneal injection of streptozocin (STZ). The rats were intragastrically administered with DHM (125 or 250 mg/kg per day) for 24 weeks. The motor ability of the rats was measured by balance beam experiment, the changes of dopaminergic (DA) neurons and the expression of autophagy initiation related protein ULK1 in the midbrains of the rats were detected by immunohistochemistry, and the protein expression levels of α-synuclein (α-syn), tyrosine hydroxylase (TH), as well as AMPK activation level, in the midbrains of the rats were detected by Western blot. The results showed that, compared with normal control, the rats with long-term T2DM exhibited motor dysfunction, increased α-syn aggregation, down-regulated TH protein expression, decreased number of DA neurons, declined activation level of AMPK, and significantly down-regulated ULK1 expression in the midbrain. DHM (250 mg/kg per day) treatment for 24 weeks significantly improved the above PD-like lesions, increased AMPK activity, and up-regulated ULK1 protein expression in T2DM rats. These results suggest that DHM may improve PD-like lesions in T2DM rats by activating AMPK/ULK1 pathway.
