Diabetic kidney disease （DKD）， one of the leading causes of end-stage renal disease， shows increasing prevalence and mortality， seriously affecting the physical and mental health of patients. As a crucial link in the occurrence and development of DKD， pyroptosis can lead to kidney cell injury and inflammation through the abnormal activation of reactive oxygen species （ROS）/thioredoxin-interacting protein （TXNIP）/NOD-like receptor protein 3 （NLRP3）， Toll-like receptor 4 （TLR4）/nuclear factor-κB （NF-κB）/NLRP3， nuclear factor erythroid 2-related factor 2 （Nrf2）/heme oxygenase-1 （HO-1）， mitogen-activated protein kinase （MAPK）/NLRP3， and hypoxia-inducible factor-1α （HIF-1α）/NLRP3 signaling pathways， which accelerate the progression of DKD. In recent years， traditional Chinese medicine （TCM） has demonstrated definite efficacy in the treatment of DKD via multiple targets and pathways. Studies have shown that various TCM active components， including glycosides， flavonoids， polyphenols， terpenoids， and alkaloids， as well as TCM compound prescriptions for clearing heat and detoxifying， tonifying deficiency and consolidating root， and eliminating stasis and descending turbidity， can target relevant signaling pathways to inhibit pyroptosis and intervene in the development of DKD， providing new possibilities for precision treatment of DKD. This article systematically reviews the relevant pathways of pyroptosis and summarizes the research achievements and mechanisms of TCM active components and compound prescriptions in the treatment of DKD via pyroptosis in recent years. This review aims to provide new directions and ideas for the treatment and research of DKD with TCM and promote the modernization and development of TCM.

A middle-aged male came to Peking Union Medical College Hospital for treatment because of "pain for 10+ years, aggravated with emotional instability for 5 years". The patient's pain had a huge impact on life, with poor results even after repeated diagnosis and treatment in other hospitals. After multi-disciplinary discussion, it had been clarified that the pain was mainly caused by gout. The disease was heavily influenced by psychosocial factors. Therefore, the patient fits the diagnosis of "Psychological and Behavioral Factors Affecting Physical Diseases". The multi-disciplinary comprehensive management of the patient was carried out to identify and treat psychological factors affecting other medical conditions. After this mental treatment was performed, the patient's conditions significantly improved. The diagnosis and treatment of this patient demonstrates the importance of the multi-disciplinary treatment team for somatic symptoms (disorders).

Objective:To investigate the current situation of the use of transjugular intrahepatic portosystemic shunt (TIPS) for portal hypertension, which should aid the development of TIPS in China.Methods:The China Portal Hypertension Alliance (CHESS) initiated this study that comprehensively investigated the basic situation of TIPS for portal hypertension in China through network research. The survey included the following: the number of surgical cases, main indications, the development of Early-TIPS, TIPS for portal vein cavernous transformation, collateral circulation embolization, intraoperative portal pressure gradient measurement, commonly used stent types, conventional anticoagulation and time, postoperative follow-up, obstacles, and the application of domestic instruments.Results:According to the survey, a total of 13 527 TIPS operations were carried out in 545 hospitals participating in the survey in 2021, and 94.1% of the hospital had the habit of routine follow-up after TIPS. Most hospitals believed that the main indications of TIPS were the control of acute bleeding (42.6%) and the prevention of rebleeding (40.7%). 48.1% of the teams carried out early or priority TIPS, 53.0% of the teams carried out TIPS for the cavernous transformation of the portal vein, and 81.0% chose routine embolization of collateral circulation during operation. Most of them used coils and biological glue as embolic materials, and 78.5% of the team routinely performed intraoperative portal pressure gradient measurements. In selecting TIPS stents, 57.1% of the hospitals woulel choose Viator-specific stents, 57.2% woulel choose conventional anticoagulation after TIPS, and the duration of anticoagulation was between 3-6 months (55.4%). The limitation of TIPS surgery was mainly due to cost (72.3%) and insufficient understanding of doctors in related departments (77.4%). Most teams accepted the domestic instruments used in TIPS (92.7%).Conclusions:This survey shows that TIPS treatment is an essential part of treating portal hypertension in China. The total number of TIPS cases is far from that of patients with portal hypertension. In the future, it is still necessary to popularize TIPS technology and further standardize surgical indications, routine operations, and instrument application.

OBJECTIVE: The present study aimed to evaluate the therapeutic effect and explore the underlying mechanisms of Longxue Tongluo Capsule (LTC) on ischemic stroke rats. METHODS: Twenty-six rats were randomly divided into four groups, including sham group, sham + LTC group, MCAO group, and MCAO + LTC group. Ischemic stroke rats were simulated by middle cerebral artery occlusion (MCAO), and LTC treatment group were orally administrated with 300 mg/kg of LTC once daily for seven consecutive days. LTC therapy was validated in terms of neurobehavioral abnormality evaluation, cerebral infarct area, and histological assessments. The plasma metabolome comparisons amongst different groups were conducted by UHPLC-Q Exactive MS in combination with subsequent multivariate statistical analysis, aiming to finding the molecules in respond to the surgery or LTC treatment. RESULTS: Intragastric administration of LTC significantly decreased not only the neurobehavioral abnormality scores but also the cerebral infarct area of MCAO rats. The interstitial edema, atrophy, and pyknosis of glial and neuronal cells occurred in the infarcted area, core area, and marginal area of cerebral cortex were improved after LTC treatment. A total of 13 potential biomarkers were observed, and Youden index of 11 biomarkers such as LysoPC, SM, and PE were more than 0.7, which were involved in neuroprotective process. The correlation and pathway analysis showed that LTC was beneficial to ischemic stroke rats via regulating glycerophospholipid and sphingolipid metabolism, together with nicotinate and nicotinamide metabolism. Heatmap and ternary analysis indicated the synergistic effect of carbohydrates and lipids may be induced by flavonoid intake from LTC. CONCLUSION The present study could provide evidence that metabolomics, as systematic approach, revealed its capacity to evaluate the holistic efficacy of TCM, and investigate the molecular mechanism underlying the clinical treatment of LTC on ischemic stroke.

Objective:To investigate characteristics and changes of skin microbiota in atopic dermatitis-like mouse models induced by different concentrations of 2,4-dinitrochlorobenzene (DNCB) .Methods:Totally, 30 male specific-pathogen-free BALB/c mice were randomly divided into 3 groups by using a random number table: negative control group topically treated with 200 μl of mixture of acetone and olive oil at a volume ratio of 3∶1 on the back twice a week for 6 consecutive weeks; high-and low-concentration DNCB groups both topically treated with 200 μl of 1% DNCB on the first and third day at the first week, followed by topical application of 200 μl of 0.5% and 0.1% DNCB, respectively, twice a week for 5 weeks from the second week. Twenty-four hours after the last treatment, the severity of skin lesions was evaluated, and the transepidermal water loss and stratum corneum hydration were measured. After the experiment, the mice were sacrificed, and skin tissues were resected from the back of the mice for histopathological examination. Full-thickness skin tissue samples were obtained from the back of 3 mice in each group. Illumina Miseq PE300 high-throughput sequencing was performed to sequence the V3-V4 variable region of 16S rRNA gene of skin microbiota on the back of the mice, and the composition and structure of the skin microbiota and changes in the relative abundance of different genera were analyzed. One-way analysis of variance was used to analyze differences in indices among the 3 groups, and the Games-Howell method was used for multiple comparisons.Results:The severity scores of skin lesions were significantly higher in the high-and low-concentration DNCB groups (9.83 ± 2.45 points, 2.71 ± 0.56 points, respectively) than in the negative control group (0.51 ± 0.12 points, t=-7.19,-2.85, respectively, both P < 0.05) . Compared with the negative control group, the high-and low-concentration DNCB groups showed significantly increased transepidermal water loss ( t=-7.72,-2.68, respectively, both P < 0.05) , but significantly decreased stratum corneum hydration ( t=6.77, 5.99, respectively, both P < 0.05) ; the transepidermal water loss was significantly higher in the high-concentration DNCB group than in the low-concentration DNCB group ( t=2.76, P < 0.05) , while no significant difference in the stratum corneum hydration was observed between the high-and low-concentration DNCB groups ( P > 0.05) . There was a significant difference in the relative abundance of Corynebacterium among the 3 groups ( F=249.85, P < 0.001) , which was highest in the high-concentration DNCB group. No significant differences in the observed species and Chao1 index of the skin samples were observed among the 3 groups (both P > 0.05) , and the Shannon index was significantly lower in the high-concentration DNCB group than in the low-concentration DNCB group and negative control group ( t=6.96,-6.37, respectively, both P < 0.05) . Conclusion:DNCB could induce atopic dermatitis-like dermatitis in mice, and the severity of skin lesions and degree of barrier function impairment were related to the concentration of DNCB; the species diversity of skin microbiota markedly decreased in the high-concentration DNCB group, indicating that high-concentration DNCB modeling has more advantages in studying microbiological changes associated with atopic dermatitis.

BACKGROUND:A large number of studies have shown that bone marrow mesenchymal stem cels (BMSCs) with differentiation ability can be used to treat kidney injury. Epimedium has good anti-inflammatory and immune restoration ability.
OBJECTIVE:To observe the effect of epimedium with BMSC transplantation on rat’s kidney disease caused by adriamycin nephrosis.
METHODS:Fifty rats were equivalently randomized to receive no treatment in control group, tail vein injection of normal saline plus intragastric injection of normal saline in model group, tail vein injection of BMSCs plus intragastric injection of epimedium decoction in combined group, tail vein injection of BMSCs in BMSCs group, and intragastric injection of epimedium decoction in epimedium group. Rat models of adriamycin nephrosis were made in the latter four groups through tail vein injection of doxorubicin hydrochloride, while rats in the control group were only given the same volume of normal saline. Twenty-four hours after modeling, rats in the latter four groups began to be given the corresponding treatments. Epimedium decoction was given in the combined and epimedium groups at a dose of 1 mL/d, for consecutive 1 week.
RESULTS AND CONCLUSION:Compared with the model group, mitigated kidney injury and reduced urinary protein level were found in rats undergoing BMSCs and/or epimedium decoction treatment; the levels of plasma albumin and catalase were significantly increased in the combined group and epimedium group, while the levels of serum cholesterol, triglycerides and malondialdehyde decreased; the mRNA expression of transforming growth factor β1 in the kidney tissues was dramaticaly declined in the combined group and BMSC group. To conclude, the combined use of epimedium and BMSCs is superior to their use alone in the treatment of kidney disease.

BACKGROUNDThe regimen of cyclophosphamide, doxorubicin, vincristine, and prednisolone (CHOP) is an efficient treatment of non-Hodgkin's lymphoma (NHL). This study aimed to assess the efficacy and toxicity of dose-adjusted CHOP alone or in combination with rituximab (R-CHOP) by examining the stem cell mobilization in NHL patients. Factors affecting the collection of CD34+ cells were also explored.

METHODSOur retrospective study included 39 patients eligible for autologous stem cell transplantation: 14 patients who expressed CD20 and were financially eligible received R-CHOP for autologous peripheral blood stem cell (APBSC) mobilization; the remaining 25 patients received CHOP.

RESULTSThe median CD34+ cell yield was 7.01×10(6) cells/kg body weight (range 1.49-28.39×10(6) cells/kg body weight), with only two patients failing to meet the target CD34+ cell harvest of ≥2.0×10(6) cells/kg body weight. The median number of apheresis procedures per patient was 1 (range 1-3). The APBSC mobilization yield of the CHOP group appeared to be higher than that of the R-CHOP group (P=0.005), whereas the success rate was similar between groups. R-CHOP elevated the complete response (CR) rate in B cell lymphoma patients as compared with CHOP (P=0.01). No significant differences in toxicity or engraftment were observed between the two groups.

CONCLUSIONThe present study demonstrated that dose-adjusted CHOP chemotherapy effectively mobilized APBSCs in NHL patients and that the addition of rituximab to dose-adjusted CHOP chemotherapy elevated the CR rate for patients with B-cell lymphoma.
