Immune-related nephropathy (IRN) refers to immune-response-mediated glomerulonephritis and is the main cause of end-stage renal failure. The pathogenesis of IRN is not fully understood; therefore, treatment is challenging. Traditional Chinese medicines (TCMs) have potent clinical effects in the treatment of the IRN conditions immunoglobulin A nephropathy, lupus nephropathy, and diabetic nephropathy. The underlying mechanisms mainly include its inhibition of inflammation; improvements to renal interstitial fibrosis, oxidative stress, autophagy, apoptosis; and regulation of immunity. In this review, we summarize the clinical symptoms of the three IRN subtypes and the use of TCM prescriptions, herbs, and bioactive compounds in treating IRN, as well as the potential mechanisms, intending to provide a reference for the future study of TCM as IRN treatments.

Objective:To explore the influencing factors of postoperative recurrence in patients with complex anal fistula, and to construct a nomogram model to predict the risk of postoperative recurrence and verify it.Methods:Clinical data of 310 patients with complex anal fistula who underwent fistulectomy in the hospital from Aug. 2019 to Mar. 2023 were retrospectively selected and divided into modeling group (93 cases) and validation group (217 cases) in a 3∶7 ratio according to system randomization method. Hospital electronic medical record system was used to collect patient baseline data and calculate the recurrence rate of patients 6 months after surgery. According to the data of the modeling group, multivariate Logistic regression was used to analyze the influencing factors of postoperative recurrence in patients with complex anal fistula. Based on the influencing factors, a nomogram model was established to predict the risk of postoperative recurrence, and external verification was performed based on the data of the validation group.Results:The recurrence rate at 6 months after operation was 20.43% (19/93) in the modeling group and 17.51% (38/217) in the validation group. There was no significant difference in recurrence rate between the two groups ( χ2=0.370, P=0.543) . The proportion of male, smoking history, diabetes mellitus, high anal fistula and unclear position of internal orifice in the recurrence group was higher than that in the non-recurrence group, and the body mass index and course of disease were higher than those in the non-recurrence group ( P<0.05) . Based on the above seven influencing factors, a nomogram model of the risk of recurrence of complex anal fistula after surgery was established. C index of the modeling group and the validation group was 0.984 and 0.798 respectively, the calibration curve was close to the ideal curve, and the Receiver operating characteristic AUC of the nomogram prediction model was>0.70, indicating that model consistency, prediction efficiency and differentiation were good. Conclusion:The nomogram prediction model based on gender, body mass index, smoking history, diabetes mellitus, course of disease, high anal fistula and internal orifice position can effectively predict the risk of postoperative recurrence in patients with complex anal fistula.

ObjectiveTo investigate the mechanism by which Shenbai Jiedu prescription （SBJDF） inhibits the proliferation of colorectal cancer （CRC） HCT116 cells. MethodAfter 48 h treatment of HCT116 cells with SBJDF （0， 0.25， 0.5， 1， 2， 4 g·L^-1）， the viability of HCT116 cells were determined by methyl thiazolyl tetrazolium （MTT） colorimetry. Following the classification of cells into blank control group and SBJDF （1， 2， 4 g·L^-1） groups， the effect of SBJDF on HCT116 cell morphology was observed under an inverted microscope. The effects of SBJDF on the proliferation of HCT116 cells and mitochondrial membrane potential （Δψm） were detected by colony formation assay and JC-1 probe， respectively. The flow cytometry was then performed for determining cell cycle distribution and apoptosis. The effects of SBJDF on cell cycle-， apoptosis-， and nuclear factor kappa-B （NF-κB） signaling pathway-related proteins were determined by Western blot. ResultSBJDF effectively inhibited the vitality of HCT116 cells and changed their morphology in a concentration-dependent manner. Compared with the blank control group， SBJDF at 1， 2， 4 g·L^-1 significantly reduced cell colony formation （P<0.05， P<0.01），and SBJDF at 2 and 4 g·L^-1 arrested the HCT116 cell cycle at G₀/G₁ phase （P<0.05， P<0.01）. Compared with the blank control group， SBJDF at 1， 2， 4 g·L^-1 remarkably down-regulated the protein expression of CyclinD₁ （P<0.05， P<0.01）. SBJDF at 2 and 4 g·L^-1 lowered the CyclinA₂ and cyclin-dependent kinase 4 （CDK4） （P<0.05， P<0.01）. SBJDF at 4 g·L^-1 reduced the cyclin-dependent kinase 1 （CDK1） （P<0.01）. Compared with the blank control group， SBJDF at 2 and 4 g·L^-1 induced HCT116 cell apoptosis， down-regulated the protein expression of anti-apoptosis-related proteins Bcl-2 and Bcl-xl as well as the NF-κB signaling pathway-related proteins IκB kinase α （IKKα），inhibitor α of NF-κB （IκBα），and phospho-NF-κB p65 （p-p65） （P<0.05， P<0.01）， and diminished the mitochondrial membrane potential of HCT116 cells. ConclusionSBJDF inhibits the proliferation of HCT116 cells， which may be related to its inhibition of the activation of NF-κB signaling pathway and the induction of cell cycle arrest and apoptosis.

Objective To explore the application of amide proton transfer (APT) imaging in differentiating glioma from treatment effect and to evaluate the diagnostic efficiency of the quantitative APT-related parameters.Methods A total of 23 patients (15 males, 8 females, age: 13-80 years) with 27 lesions who had underwent APT imaging in Tongji Hospital(Wuhan, China) from October 2014 to June 2015 were enrolled in this prospective study.The scan protocols were MRI normal plain scanning, diffusion WI, contrast-enhancement T1WI and APT imaging.Both the magnetization transfer ratio (MTR) and the relative MTR (rMTR) of lesions were manually measured by drawing ROI in the functional post-processing workstation.The results were compared with those of pathologic examinations and radiographic follow-up (≥3 months).Mann-Whitney u test was used to analyze the data.Results Compared with contralateral white matter, the primary gliomas (n=12) and recurrent gliomas (n=8) manifested hyper-intensity, while the treatment induced injuries (n=7) showed iso-or hypo-intensity.The difference of MTR between tumors and treatment effects was significant (102.78(101.93,103.84) vs 100.17(99.94, 100.63);z=-3.76, P<0.01), so was the difference of rMTR between tumors and treatment effects (3.92%(2.69%,4.67%) vs 0.47%(-0.79%,1.11%);z=-3.43, P<0.01).Both those two quantitative parameters exhibited excellent diagnostic performance with the AUC of 0.986 and 0.943.The sensitivity, specificity and accuracy of MTR were 100%(20/20), 6/7 and 96.3%(26/27) in the threshold of 100.68, while those of rMTR were 95.0%(19/20), 6/7 and 92.6%(25/27) in the threshold of 1.66%.Conclusions Combined with the routine MRI images, APT imaging can provide excellent qualitative and quantitative information in differentiating glioma from treatment effect.Both MTR and rMTR are helpful for the differentiation with high sensitivity and specificity and can be used as non-invasive imaging biomarkers in evaluating treatment effect of glioma.

Objective To evaluate the clinical results of arthroscopic repair of combined Bankart and superior labrum anterior to posterior (SLAP)lesions in patients with recurrent shoulder dislocations.Methods Between May 2011 and January 2015,we reviewed 15 cases with combined Bankart and SLAP lesions with recurrent shoulder dislocations who underwent arthroscopic repair.Their average age during surgery was 24.2 years (ranging from 16 to 38 years).During the operation,we began by repairing the unstable SLAP lesion with absorbable suture anchors before we repaired Bankart lesion from the inferior to superior.Fifteen patients in the control group had isolated Bankart lesions without SLAP lesions and underwent arthroscopic repair.Their mean age was 24.6 years (ranging from 18 to 35 years).The preoperative and postoperative results were analyzed by Visual Analogue Scale (VAS)for pain,the range of motion,American Shoulder and Elbow Surgeon (ASES)and Rowe Shoulder Scores Systems.We compared the results with the isolated Bankart lesion. Results For patients who underwent arthroscopic repair of combined Bankart and SLAP lesions,the mean postoperative follow-up period was 15 months (ranging from 13 to 28 months),vs 22 months (ranging from 21 to 34 months)in the control group.VAS for pain was decreased from preoperative 4.9 to postoperative 1.9 (P <0.05).Mean ASES and Rowe Shoulder Scores were improved from preoperative 56.4 and 33.7 to postoperative 91.8 and 94.1,respectively (P <0.05). Recurrent dislocation was not observed until the last follow-up and anterior instability in two groups was not noted during the physical examination.Compared with the isolated Bankart lesion group,no statistical significance was found in the ASES score,Rowe Shoulder Score,or VAS for pain (P >0.05 ).Anterior flexion,abduction,and internal rotation of the affected shoulder during the last follow-up were normal after surgery.Conclusion For recurrent dislocation of the shoulder with combined Bankart and SLAP lesion,arthroscopic repair using absorbable suture anchors can achieve favorable clinical results.It can effectively restore shoulder function.

Objetive To explore bacteriological changes and susceptible factor of nosocomial infection in neonatal intensive care unit (NICU). Methods The clinical data from 5543 hospitalized neonates during January 2010 to December 2015 were retrospectively analyzed. Results Nosocomial infection rate during the study period was 8 . 75 %. The most common pathogen of nosocomial infection was Staphylococcus epidermidis, followed by Escherichia coli and Klebsiella pneumoniae. Respiratory infection accounted for 37.73% and blood infection 37.53%. 36.74% blood samples were tested to be positive, and 32.67% sputum were positive. In the first three years, the main pathogens of nosocomial infection were Candida albicans, Klebsiella pneumonia, and Staphylococcus aureus; in the last three years, the main pathogens were Staphylococcus aureus, Escherichia coli, and Klebsiella pneumoniae. The susceptible factors of nosocomial infection in NICU were gestational age?

OBJECTIVETo explore the correlation between UGT1A1 (*28, *60 and * 93) polymorphism and the adverse reactions in small cell lung cancer patients after irinotecan chemotherapy.

METHODSClinical data of 58 small cell lung cancer patients in extensive stage treated in our hospital were retrospectively analyzed. Polymerase chain reaction was used to amplify the UTG, and direct sequencing was performed to determine the UGT polymorphism. The adverse reactions ≥ grade 3 after irinotecan chemotherapy in patients with different UGT genotype were analyzed.

RESULTSAmongthe 58 patients with extensive stage small cell lung cancer, there were 45 (77.6%) cases of wild type UGT1A1*28, 40 (69.0%) cases of wild type UGT1A1* 93, 38 (65.5%) cases of wild type UGT1A1*60, 18 cases of mutation in UGT1A1* 93 and 20 cases of mutation in UGT1A1*60. In UGT1A1 promoter position 28, there were 8 (13.8%) cases of TA5 mutation and 5 (8.6%) cases of TA7 mutation. Among the patients with TA5 mutation, 5 cases had ≥ grade 3 diarrhea, 3 cases had ≥ grade 3 leucopenia and 3 cases had ≥ grade 3 neutropenia, while among the patients with UGT1A1 * 93 mutation, 7 cases had ≥ grade 3 diarrhea, 6 cases had ≥ grade 3 leucopenia and 4 cases had ≥ grade 3 neutropenia.

CONCLUSIONSTA5 and UGT1A1* 93 mutation increase the risk of diarrhea and ≥ grade 3 leukopenia and neutropenia, however, wild type UGT1A1 (*28, * 93, *60) and mutant UGT1A1*60 do not increase those risks. Further prospective study in a larger number of patients is needed to clarify the association between UGT1A1*28, UGT1A1* 93 and UGT1A1*60 polymorphism and adverse reactions of irinotecan, and to help clinicians in choosing a better therapeutic modality for personalized chemotherapy to improve curative effect and reduce adverse reactions.
