Pathogenesis and Differentiated Treatment Strategies of Childhood Tic Disorders Based on WANG Xugao's “Thirty Methods of Treating the Liver” / 中医杂志

Based on WANG Xugao's “thirty methods of treating the liver”， it is believed that the occurrence and development of childhood tic disorders follow the dynamic progression from liver qi disease to liver fire disease and then liver wind disease. The basic pathogenesis of three stages are characterized by binding constraint of liver qi， liver fire hyperactivity， and internal stirring of liver wind. Moreover， liver-blood deficiency and stagnation， and malnutrition of liver yin as the main point in terms of the imbalance of liver qi， blood， yin， and yang should be considered， as well as the imbalance relationship of the five zang organs such as the involvement of other organs and the gradually reach of the other organs. Guided by the principles of “thirty methods of treating the liver”， the treatment of tic disorders in liver qi stage should focus on soothing the liver and rectifying qi， soothing the liver and unblocking the collaterals， using Xiaochaihu Decoction （小柴胡汤） and Sini Powder （四逆散）. The treatment of tic disorders in liver fire stage involves clearing， draining and resolving liver heat， using Longdan Xiegan Decoction （龙胆泻肝汤）， Xieqing Pill （泻青丸）， Danggui Longhui Pill （当归龙荟丸）， and Huagan Decoction （化肝煎）. The treatment of tic disorders in liver wind stage involves extinguishing wind and subduing yang， using Lingjiao Gouteng Decoction （羚角钩藤汤） and Liuwei Dihuang Pill （六味地黄丸）. Throughout the treatment process， attention should be paid to harmonizing the liver's qi， blood， yin， and yang， as well as addressing the pathology of other organs.

Based on the metabolic mechanism of UHPLC-Q-Exactive-MS Hippocampus to delay the aging of Drosophila melanogaster / 药学学报

Based on the UHPLC-Q-Exactive-MS metabonomics technology, the effect of Hippocampus kuda Bleeker on the life span of Drosophila melanogaster was studied, and the change rule of endogenous metabolites in the aging process of Drosophila melanogaster after the intervention of Hippocampus kuda Bleeker japonicus was explored to clarify the anti-aging mechanism of Hippocampus. The natural aging model of Drosophila melanogaster was used. Different doses of raw Hippocampus and fried Hippocampus were given to observe the effects on the life span, climbing ability, sexual activity, and antioxidant enzyme activity of Drosophila melanogaster. Based on UHPLC-Q-Exactive-MS metabolomics technology, the metabolic profile of the aging Drosophila melanogaster was analyzed using metabonomics technology to explore the mechanism of Hippocampus kuda Bleeker delaying the aging of Drosophila melanogaster. The results showed that raw Hippocampus and crispy Hippocampus (1, 4 mg·mL-1) could significantly prolong the average life span, median life span and maximum life span of male fruit flies, and significantly improve the climbing ability and sexual vitality of fruit flies. Catalase (CAT) and aldehyde content were increased, while malonaldehyde (MDA) content was decreased. Through metabonomics technology, it was identified that the Hippocampus can significantly recall 16 metabolites and participate in the biosynthesis of phenylalanine, tyrosine and tryptophan, starch and sucrose metabolism, tyrosine metabolism, cysteine and methionine metabolism, and histidine metabolism. The anti-aging mechanism is related to amino acid metabolism and sugar metabolism, which provides a substantial scientific basis for the development and utilization of Hippocampus and clarifying its role in senile diseases. The animal experiment of this study was approved by the Ethics Committee of Shanxi University (approval number: SXULL2021028).

Expert Consensus on Clinical Diseases Responding Specifically to Traditional Chinese Medicine：Membranous Nephropathy / 中国实验方剂学杂志

Traditional Chinese medicine （TCM） is a great treasure house， exhibiting unique advantages in the treatment of some difficult and critical diseases. The incidence rate of membranous nephropathy has increased year by year in recent years， and has become the first cause of primary glomerular diseases. However， its pathogenesis is not clear. Modern medicine often uses immunosuppressive therapy， but it often faces the problems of high side effects and high recurrence rate. The China Association of Chinese Medicine （CACM） invited clinical experts of TCM and western medicine to fully discuss membranous nephropathy， which was later confirmed to be one of the clinical diseases responding specifically to TCM. Apart from summarizing the pathogenesis and clinical diagnosis and treatment of membranous nephropathy in both TCM and western medicine， this paper also detailed TCM cognition， syndrome differentiation， and therapeutic schemes of membranous nephropathy， aiming to improve the clinical remission rate of membranous nephropathy and provide reference for its clinical treatment.

Cathepsin B Affects the Activation of Nucleotide-binding Domain and Leucine-rich-repeat-containing Family and Pyrin Domain-containing 3 Inflammasome via Transient Receptor Potential Mucolipin-1 / 中国医学科学院学报

Objective To explore the effects of cathepsin B(CTSB)on the activation of nucleotide-binding domain and leucine-rich-repeat-containing family and pyrin domain-containing 3(NLRP3)inflammasome via transient receptor potential mucolipin-1(TRPML1)in cell oxidative stress model and specific gene silencing cell model. Methods BV2 cells cultured in vivo were treated separately or simultaneously with hydrogen peroxide(HO),calcium-sensitive receptor agonist gadolinium trichloride(GdCl),and CTSB inhibitor CA-074Me,and interleukin-1(IL-1)beta and caspase-1 protein were detected by enzyme-linked immunosorbent assay.The growth activity of BV2 cells in each group was measured by MTT.BV2 cells were treated with different concentrations of HO.Cystatin C mRNA and TRPML1 mRNA in BV2 cells were detected by real-time quantitative polymerase chain reaction and the proteins of TRPML1,CTSB,cathepsin D(CTSD),cathepsin L(CTSL)and cathepsin V(CTSV)were detected by Western blot.Specific small interfering RNA was designed for TRPML1 gene target sequence.TRPML1 gene silencing cell lines(named Tr-si-Bv2 cells)were established in BV2 cells and treated with or without HO.TRPML1,CTSB and transcription factor EB(TFEB)proteins in Tr-si-Bv2 cells or control cells were detected by Western blot. Results After treatment with HO,the expression of caspase-1 protein and NLRP3 mRNA in BV2 cells was increased,and IL-1beta protein in BV2 cells was significantly increased after treatment with GdCl(P=0.0036).After treatment with CA-074Me,the doses of NLRP3 mRNA(P=0.037),caspase-1(P=0.021),and IL-1β(P= 0.036)were significantly reduced.Cells in the HO group and HO+GdCl group grew more slowly.The expressions of CTSB mRNA and TRPML1 mRNA,or CTSB and TRPML1 proteins in BV2 cells in the treatment group with 200 μmol/L of HO concentration were similar.HO-induced CTSB protein expression was inhibited after silencing TRPML1 gene.The changes of other cathepsins were not affected for the different concentration of HO.In the BV2 cells treated with TRPML1 gene silencing,the expression of CTSB protein was significantly reduced and the difference was statistically significant(P=0.021)between the HO +siRNA treatment group and the HO treatment group.Conclusion CTSB regulates the activation of NLRP3 inflammasome in the oxidative stress model of microglia cells,probably mediated by calcium channel protein TRPML1.

Quality characterization analysis of single decoction and merger decoction of Baihu and Guizhi / 中国中药杂志

To study the differences and similarities in pharmaceutical characterization and pharmacodynamic characterization between the single decoction and merger decoction of Baihu and Guizhi. The same technology parameters were used to prepare Baihu and Guizhi single decoticon and merger decoction extracts, and then the differences and similarities in pharmaceutical characterization were analyzed based on their HPLC fingerprint, content of index components, and the extraction content. The pharmacodynamic differences and similarities were analyzed by inflammatory model and pain model. There was no significant difference in HPLC chromatographic peak, but the peak area value reflected the difference of quantity to some extent. It was found that the peak value of single Rhizoma anemarrhenae and Cassia twig decoction was less than the peak of their merger decoction, but the peak value of single honey-fried Licorice root decoction was greater than the peak of merger decoction． The contents of neomangiferin, mangiferin and timosaponin B Ⅱ among index components as well as extraction content in merger decoction were higher than those in single decoction． The contents of liquiritin and glycyrrhizic acid as well as extraction content in merger decoction were lower than those in single decoction． There was no significant difference in the content of cinnamicacid and its extraction content between merger decoction and single decoction. According to the efficacy experiment, both of them showed significant anti-inflammatory and analgesic effects. However, the merger decoction showed faster anti-inflammation effect, and longer analgesic effect. It can be concluded that the merger decoction and single decoction of Baihu and Guizhi have the same material basis, and the merger decoction is better for the dissolution of the active ingredients in this recipe, and is more beneficial to the therapeutic effect.

Analyze moisture transformation and transport rules during processing of Paeoniae Radix Alba by using low-field NMR / 中国中药杂志

Moisture status and content during the processing of Paeoniae Radix Alba were studied by nuclear magnetic resonance (NMR) and nuclear magnetic resonance imaging (MRI) to investigate the changes of transverse relaxation time (T ₂) and MRI images during boiling and drying processes of Paeoniae Radix Alba. The results showed that water in Paeoniae Radix Alba fresh products was major of free water, and in the boiling process, the content of free water increased whereas the content of bound water declined. At the end of boiling, content of free water reached over 90%. During the drying process, T ₂ moved to the left, and moisture mobility was reduced. The MRI image directly showed that moisture transfer was outside-in process for both increase and decrease. At the end of drying, remaining moisture was mainly present in inner layer of Paeoniae Radix Alba. Quality and appearance were affected by the change of moisture during processing process of medicinal herbs. NMR and MRI could provide direct reference evidence for its moisture changes, and the results of this study could provide direct references and technical support for optimization of processing process of root medicinal materials and evaluation of Chinese herbal pieces.

Study variables included International Prostate Symptom Score, quality of life, maximum urinary flow rate, and incidence of complications.</p><p><b>RESULTS</b>HoLEP were performed successfully completed, not patients which occurs as electric cutting syndrome. The operation time was (60.8 ± 18.4) minutes; average resection of prostate quality was (45.4 ± 24.4) g. The hemoglobin reduce though surgery was (1.81 ± 0.93) g/L; percentage of red blood cell change was 1.24% ± 0.43%, and sodium blood drop was (1.14 ± 0.35) mmol/L. Postoperative patients of hospital stay (3.1 ± 1.1) days, average time of indwelling catheter time was (2.3 ± 0.8) days. Patients were followed up for 6-131 months time, an average of 32.4 months. Postoperative patients with international prostate symptom score progressive declined. The quality of life score was 2.2 ± 1.7, and it less than preoperative (5.7 ± 3.3, t = 2.447, P < 0.01). The time of follow-up droped further, and postoperative comparative differences have statistical significance (t = 2.179, 2.228, 2.306 and 2.365, P < 0.05). The maximum urinary flow rate also improved (P < 0.05). Postoperative complications included bladder neck contracture (4 cases), urinary tract infection (107 cases), urethral stricture (11 cases) and urinary incontinence (11 cases). The 11 patients reoperation.</p><p><b>CONCLUSIONS</b>HoLEP treatment of benign prostatic hyperplasia could achieve the advantages of open surgery the same effect. It had fewer damage, faster recovery, fewer complications, and is a good treatment option.</p>

Mechanism of adult offspring rats'anxiety-like behavior induced by morphine addiction and withdrawal in parents before mating / 中华行为医学与脑科学杂志

ObjectiveTo explore the possible mechanism of adult offspring rats'anxiety-like behavior induced by parents experienced morphine addiction and withdrawal.MethodsEstablishing the model of Sprague-Dawley rats morphine addiction,Male and female rats were mated after morphine withdrawal 21 days.Meaning-while,saline control group was established in the same method.5 female and 5 male offspring's brains were obtained to observe the neuronal morphology of hippocampal CA1 through Golgi staining when they were 8 weeks old,the same number of female and male's hippocampus were derived after deeply anesthetized to perform the whole genome expression profiles analysis.ResultsThe total length and the number of basal dendrites branches on hippocampal CA1 neurons in offspring of morphine groups were significantly decreased compared to the offspring of saline group.Comparison with the offspring of saline group,663 up-regulated genes (ratios ≥2.0) and 499 down-regulated genes ( ratios ≤0.5 ) were detected in the male offspring of morphine groups,and 350 up-regulated genes (ratios ≥2.0) and 188 down-regulated genes (ratios ≤0.5) were done in the female.Furthermore,they included many genes associated with regulation of emotional behavior,such as 5-HT2c receptor up-regulation 7-fold,Igf-2 up-regulation 7.1-fold and reelin down-regulation 3.3-fold were observed.ConclusionExperienced morphine addiction and withdrawal in parents prior to mating leads to dysplasia of dendritic morphology in hippocampal CA1 neurons of adult offspring rats,and 5-HT2c,Igf-2,reelin expressing abnormally,which may be the possible mechanism of anxiety-like behavior in adult offspring rats.
