Objective:
To investigate the efficacy, safety, and traditional Chinese medicine (TCM) medication patterns of rituximab (RTX) combined with TCM on treating children with steroid-dependent nephrotic syndrome (SDNS).
Methods:
One hundred and forty-three children with SDNS who visited the Pediatric Nephrology Department of the First Affiliated Hospital of Henan University of Chinese Medicine from January 2018 to December 2022 were enrolled. A cohort study design was adopted, with " RTX treatment" as the exposure factor. Children who met this exposure factor were assigned to the RTX cohort (RTX, glucocorticoid, immunosuppressive agent, combined with traditional Chinese medicine syndrome differentiation treatment), whereas those who did not were assigned to the basic treatment cohort (glucocorticoid, immunosuppressive agent, combined with traditional Chinese medicine syndrome differentiation treatment ), and followed up for 6 months. The frequency of urinary protein recurrences, urinary protein remission duration, proportion and duration of steroid reduction and cessation, cumulative usage of steroids, proportion of recurrence, recurrence amount of steroid used, efficacy of TCM syndrome, and laboratory and safety indicators after treatment, and height and CD19+ B cell count before and after treatment were compared between the two cohorts. The medication patterns of TCM in the two cohorts were analyzed using frequency statistics, association rule analysis, and systematic clustering analysis.
Results:
Compared with the basic treatment cohort, the RTX cohort showed a decrease in the frequency of urinary protein recurrence, extended sustained remission of urinary protein, an increase in the proportion of steroid reduction and cessation, a shorter duration of steroid reduction and cessation, a decrease in cumulative steroid dosage, a lower recurrence rate, a decrease in CD19+ B cell count, and a decrease in 24-h urinary total protein quantification and the level of cholesterol (P<0.05). No significant difference in the recurrence amount of steroid used, height, TCM syndrome efficacy, albumin, aspartate transaminase, blood urea nitrogen, platelet count, and safety indicators between the two cohorts. Children with SDNS were mostly characterized by qi and yin deficiency syndrome, followed by spleen and kidney yang deficiency syndrome. A total of 175 TCMs were included, including 28 high-frequency drugs such as Huangqi, Fuling, Gancao, Baizhu, Dangshen, and Jiuyurou. The primary use of medication is to nourish the qi and spleen, nourish the kidney, and warm yang. The analysis of association rules yielded eight binary associations and ten three-phase associations, with Huangqi, Baizhu, Fuling, and Dangshen, being the most closely related. Cluster analysis identified four TCM combinations, primarily focusing on tonifying kidney and replenishing essence, benefiting qi and nourishing yin, and removing blood stasis.
Conclusion
RTX combined with TCM syndrome differentiation treatment can reduce the recurrence frequency of SDNS, prolong the remission period, reduce the glucocorticoid dosage, and have no marked effect on height growth. No apparent adverse reactions were observed. TCM should focus on nourishing qi and yin while removing blood stasis.

OBJECTIVE To investigate the effects of Tripterygium wilfordii multiglycoside (TWM) on renal injury in diabetic nephropathy (DN) rats through tumor protein p53/microRNA-214 (miR-214)/UNC-51-like kinase 1 (ULK1) axis. METHODS Male SD rats were randomly divided into normal group (n=6) and modeling group (n=28); the modeling group was fed with high fat and high glucose plus intraperitoneal injection of streptozotocin to establish DN model. The modeled rats were randomly divided into model group, valsartan group [8.33 mg/(kg·d)] and TWM group[6.25 mg/(kg·d)], with 8 rats in each group. Rats in each group were gavaged with the corresponding medication or normal saline, once a day, for 6 consecutive weeks. After the last medication, liver and renal function indexes [24 h urinary total protein (24 h-UTP), blood urea nitrogen (BUN), serum creatinine (SCr), albumin (ALB), alanine transaminase (ALT)], blood lipid indexes (triglycerides, total cholesterol) and blood glucose index (fasting blood glucose) in urine/blood sample of rats were detected in each group. Renal pathologic change was observed, protein and mRNA expressions of p53, ULK1, Beclin-1 and microtubule-associated protein 1 light chain 3 (LC3), and expression of miR-214 in renal tissue were also determined. RESULTS Compared with the normal group, the renal tubular epithelium of rats in the model group showed obvious edema, cell swelling, accompanied by lymphocyte infiltration; the levels of 24h-UTP, BUN, SCr, ALT and glycolipid indexes, the expressions of p53 protein and mRNA, as well as the expression of miR-214 in rats in the model group and administration groups were significantly increased or up-regulated, while ALB level, LC3-Ⅱ/LC3-Ⅰ, the expressions of LC3 mRNA, the expressions of ULK1, Beclin-1 protein and mRNA were significantly decreased or down-regulated (P<0.01). Compared with the model group, the histopathological damage of the kidney in rats was improved in administration groups; the levels of 24 h-UTP, BUN, SCr, ALT and glycolipid indexes, the expressions of p53 protein and mRNA, as well as the expression of miR-214 were all significantly decreased or down-regulated, while ALB level, LC3-Ⅱ/LC3-Ⅰ, the expressions of LC3 mRNA, the expressions of ULK1 and Beclin-1 protein and mRNA were significantly increased or up-regulated (P<0.01). CONCLUSIONS TG can alleviate renal damage in DN rats, and improve their liver and renal function, as well as glucose and lipid levels. These effects may be related to the regulation of the p53/miR-214/ULK1 axis and the restoration of cellular autophagy.

ObjectiveTo analyze the clinical treatment plan and traditional Chinese medicine (TCM) medication rule of children with primary nephrotic syndrome (PNS) in the First Affiliated Hospital of Henan University of Chinese Medicine. MethodsThe gender and age of children firstly diagnosed with nephrotic syndrome in the pediatric nephrology department of the First Affiliated Hospital of Henan University of Chinese Medicine from November 2019 to December 2022 were collected, and the use of immunosuppressive agents and related frequencies were counted. According to the inclusion and exclusion criteria, an independent TCM prescription database for children with nephrotic syndrome was established. Excel was used to analyze the relevant information of the literature. The frequency counting, association rule analysis, and cluster analysis were carried out on TCM in the prescription, and the high-frequent drugs were analyzed. Results(1) General information: A total of 711 children were included, consisting of 522 males (73.42%) and 189 females (26.58%). The ratio of male to female was about 2.76∶1. The disease mainly occurred in infants and preschool age, and the average age of onset was (4.74 ± 3.48) years old. (2) Clinical treatment plan and use of immunosuppressive agents: Of the 711 children with PNS, 237 were treated with hormone alone (32.33%), and 474 (66.67%) received immunosuppressive agents combined with hormones. In the initial treatment, hormone combined with Tacrolimus (TAC) was the preferred treatment (32.91%). For children with refractory PNS who exhibited poor clinical efficacy, Rituximab (RTX) was mostly used for treatment, with a ratio of up to 23.63%. (3) TCM syndrome and medication rule: In PNS syndrome differentiation, Qi and Yin deficiency was identified as the main syndrome. This involved a total of 477 cases, accounting for 67.09%. Yang deficiency of spleen and kidney was observed in 118 cases, accounting for 16.60%. A total of 711 children were included, of which 706 children were treated with TCM. This involved a total of 706 prescriptions, 226 TCM, and 9 793 frequencies. There were 30 herbs used more than 95 times. The top five TCM were Radix et Rhizoma Glycyrrhizae (81.16%), Radix Astragali (71.81%), Poria (68.84%), Rhizoma Atractylodis Macrocephalae (63.60%), and Fructus Corni (57.37%). The drug association rules and network diagram showed that the combination of ''Radix Astragali-Rhizoma Atractylodis Macrocephalae-Poria'' was the closest, and five types of combinations were obtained by cluster analysis. ConclusionIn the diagnosis and treatment of PNS in children, TAC combined with hormones shows good clinical efficacy and high safety. For children with refractory PNS, RTX combined with hormones can be used. TCM medication for PNS should follow the basic principles of strengthening the body and vital Qi and make good use of drugs such as Radix Astragali, Poria, Rhizoma Atractylodis Macrocephalae, and cornus to regulate the Yin and Yang balance and achieve better clinical efficacy.

Guided by the theory of "kidney generates marrow", the study elaborates the viewpoint that the route of Yin Heel Channel (阴跷脉) is consistent with the "kidney-marrow-brain" axis from the perspective of the circulation of the meridians and the relationship between the zang-fu organs. Accordingly, it is believed that disease of Yin Heel Channel and dysfunction of the "kidney-marrow-brain" axis are the core pathogenesis of children enuresis, and it is elaborated from the following three major aspects, firstly, insufficient kidney essence, dysfunction of the "kidney-marrow-brain" axis, secondly, disease of Yin Heel Channel and deficiency and cold in lower jiao, and thirdly, disease of Yin Heel Channel and loss of nourishment of Chong Vessel. It is proposed to use the mode of "firstly needle, secondly moxibustion, and lastly consolidation" to treat children enuresis. Needle is to adjust yin and yang, warm yang and tonify kidney, and wake up the brain and open the orifices. The acupoints in Yin Heel Channel such as Zhaohai (KI 6), Jiaoxin (KI 8) and confluence points of the eight extraordinary vessels such as Waiguan (TE 5), Zulinqi (GB 41) are used, together with Baihui (GV 20), Yintang (EX-HN 3), Guanyuan (CV 4), Qixue (KI 13), Dazhong (KI 4). Moxibustion is to reinforce healthy qi and warm yang, bank up the root and consolidate the original qi by moxibustion at Shenque (CV 8), Mingmen (GV 4), and Xuanshu (GV 5). Consolidation is to use acupoints application to consolidate the therapeutic effect, and Guanyuan (CV 4) & Pangguangshu (BL 28), Qihai (CV 6) & Zhishi (BL 52), and Shenque (CV 8) & Ciliao (BL 32) are commonly used as the three groups of acupoints to warm the kidney and stop collapse, regulate and tonify the qi and blood.

OBJECTIVE To explore the renal protective mechanism of Shenbining granules on IgA nephropathy (IgAN) rats based on mitochondrial quality control system. METHODS IgAN rat model was established by the method of “bovine serum albumin+carbon tetrachloride+lipopolysaccharide”. The model rats were randomly divided into model group, prednisone acetate group (6.25 mg/kg), Shenbining equal-dose group (4.1 g/kg) and Shenbining high-dose group (20.5 g/kg). The normal rats were taken as the normal control group, with 12 rats in each group. Rats were given corresponding drugs or distilled water intragastrically in each group, once a day, for 4 consecutive weeks. After the last medication, the 24 h total urinary protein (24 h- UTP) and erythrocyte count in urine were determined, and the levels of serum creatinine (Scr), blood urea nitrogen (BUN), albumin (ALB) and alanine transaminase (ALT) were also detected. The histopathological changes in the kidneys and changes in IgA deposition in the mesangial area of the kidney were observed. mRNA and protein expression levels of PTEN-induced putative kinase 1 (PINK1), E3 ubiquitin ligase(Parkin), microtubule-associated protein 1 light chain-3 (LC3), dynamin-related protein 1 (Drp1) and mitofusin 2 (Mfn2) were detected in the kidney tissues of rats. RESULTS Compared with model group, 24 h-UTP, urinary erythrocyte count, ALT, BUN and Scr levels, LC3-Ⅱ/LC3-Ⅰ mRNA ratio, mRNA and protein expressions of Drp1 were reduced significantly in prednisone acetate group, Shenbining equal-dose group and Shenbining high-dose group (P<0.05); ALB level, LC3-Ⅱ/LC3-Ⅰ protein ratio, mRNA and protein expressions of PINK1, Parkin and Mfn2 were increased significantly (P<0.05); the pathological morphology of kidney tissue in rats was significantly improved, and IgA deposition was significantly reduced. CONCLUSIONS Shenbining granule may reduce renal pathological injury in IgAN rats and protect renal function by activating the PINK1/Parkin pathway, enhancing mitochondrial autophagy, and correcting mitochondrial kinetic disorders.

Pien Tze Huang(PZH),a class-1 nationally protected traditional Chinese medicine(TCM),has been used to treat liver diseases such as hepatitis;however,the effect of PZH on the progression of sepsis is un-known.Here,we reported that PZH attenuated lipopolysaccharide(LPS)-induced sepsis in mice and reduced LPS-induced production of proinflammatory cytokines in macrophages by inhibiting the acti-vation of mitogen-activated protein kinase(MAPK)and nuclear factor-kappa B(NF-κB)signalling.Mechanistically,PZH stimulated signal transducer and activator of transcription 3(STAT3)phosphory-lation to induce the expression of A20,which could inhibit the activation of NF-κB and MAPK signalling.Knockdown of the bile acid(BA)receptor G protein-coupled bile acid receptor 1(TGR5)in macrophages abolished the effects of PZH on STAT3 phosphorylation and A20 induction,as well as the LPS-induced inflammatory response,suggesting that BAs in PZH may mediate its anti-inflammatory effects by acti-vating TGR5.Consistently,deprivation of BAs in PZH by cholestyramine resin reduced the effects of PZH on the expression of phosphorylated-STAT3 and A20,the activation of NF-κB and MAPK signalling,and the production of proinflammatory cytokines,whereas the addition of BAs to cholestyramine resin-treated PZH partially restored the inhibitory effects on the production of proinflammatory cytokines.Overall,our study identifies BAs as the effective components in PZH that activate TGR5-STAT3-A20 signalling to ameliorate LPS-induced sepsis.

ObjectiveTo explore the underlying mechanism of Tripterygium wilfordii polyglycoside tablets (TWPT) in the prevention and treatment of kidney injury in diabetic nephropathy (DN) through the nuclear factor of activated T-cells 2(NFAT2)/cyclooxygenase-2(COX-2) pathway. MethodForty-two male SD rats of SPF grade were selected and randomly divided into a normal group (n=8) and an experimental group (n=34) after one week of adaptive feeding. The rats in the normal group were fed conventionally. The DN model was established in rats of the experimental group by intraperitoneal injection of streptozotocin (STZ) following one week of feeding on a high-fat and high-glucose diet. After the death and failure cases during modeling were eliminated, the remaining 24 model rats were randomly divided into model group, valsartan (8.33 mg·kg-1·d-1) group, and TWPT (5 mg·kg-1·d-1) group. Rats in normal group and model group were given equal amounts of normal saline by gavage. After six weeks, body weight was measured and urine samples were collected. Blood samples were collected from the abdominal aorta, and then the rats were sacrificed for sampling. Biochemical indicators, such as serum blood urea nitrogen (BUN), serum creatinine (SCr), alanine aminotransferase (ALT), blood lipid, blood glucose, and 24-hour urine total protein (24 h UTP), were determined. Hematoxylin-eosin (HE) staining and Masson staining were used to observe the pathology of the kidney. Enzyme-linked immunosorbent assay (ELISA) was used to detect NFAT2 and COX-2 expression levels in the serum. Western blot and Real-time fluorescence quantitative polymerase chain reaction(Real-time PCR)were adopted to detect NFAT2, COX-2 protein and mRNA expression in kidney tissues, respectively. ResultCompared with the normal group, the model group showed elevated 24 h UTP, BUN, SCr, CHO, TG, and FBG, increased serum NFAT2 and COX-2 production and expression (P<0.01), and elevated protein and mRNA expression of NFAT2 and COX-2 in kidney tissues (P<0.01). In addition, the pathology of the kidney showed enlarged glomeruli, mild proliferation of mesangial cells, and widened mesangial stroma. Compared with the model group, the TWPT group showed decreased 24 h UTP, BUN, SCr, CHO, TG, and FBG (P<0.05,P<0.01), basically normal glomerular morphology, decreased expression of serum NFAT2 and COX-2 (P<0.01), and down-regulated protein and mRNA expression of NFAT2 and COX-2 in kidney tissues (P<0.01). ConclusionTWPT can alleviate 24 h UTP in DN model rats, protect renal function, and improve renal pathology, and its mechanism of action may be related to the down-regulation of NFAT2/COX-2 expression in the serum and kidney tissues.
