Biologics in treatment of lupus nephritis / 中华肾脏病杂志

Systemic lupus erythematosus (SLE) is an autoimmune disease that causes damage to multiple vital tissues and target organs, and lupus nephritis (LN) is a serious complication of SLE involving the kidneys. The use of glucocorticoids and immunosuppressants has been dominant in the treatment strategy of LN, while their adverse effects have also raised concerns. In recent years, the development and use of biologics have provided new ideas for the treatment of LN and have also achieved positive efficacy in several clinical trials in SLE and LN. Biologics can be divided into monoclonal antibodies and recombinant proteins, which exert therapeutic effects on SLE and LN through a variety of mechanisms at the cellular-molecular level. In this article, we review recent research advances in the treatment of SLE and LN from the perspective of the different mechanisms of action of biologics.

Clinicopathologic characteristics of lupus nephritis with positive antineutrophil cytoplasmic antibody / 中华肾脏病杂志

Objective:To explore the clinical and histopathologic features of lupus nephritis (LN) patients with positive antineutrophil cytoplasmic antibody (ANCA), so as to provide more theoretical basis to recognize and treat this disease.Methods:Clinical data of biopsy-proven LN patients with ANCA test in the First Affiliated Hospital of Sun Yat-sen University from November 1, 2002 to September 11, 2020 were collected and analyzed retrospectively. The difference of clinical data, laboratory examination, and pathological examination of renal biopsy between ANCA-positive group and ANCA-negative group. The clinicopathological characteristics between different ANCA serotypes were compared.Results:A total of 1 304 patients with LN confirmed by renal biopsy and ANCA test results were enrolled. Eighty ANCA-positive patients from 1 304 LN patients were screened. There are 55(68.8%) ANCA-positive LN patients with positive anti-myeloperoxidase antibodies (MPO). There were 14(17.5%) ANCA-positive LN patients with positive anti-proteinase 3 antibodies (PR3), and 11(13.8%) ANCA-positive patients with double positive antibodies of MPO and PR3. ANCA-positive LN patients had significantly higher serum creatinine [135.5(68.0, 361.8) μmol/L vs 88.0(64.0, 165.0) μmol/L, P=0.004] and blood urea nitrogen [12.35(6.35, 21.18) mmol/L vs 8.60 (5.50, 15.70) mmol/L, P=0.026] as well as lower estimated glomerular filtration rate [45.70(13.83, 84.10) ml·min -1·(1.73 m 2) -1 vs 66.75(38.43, 96.22) ml·min -1·(1.73 m 2) -1, P=0.001] than ANCA-negative patients (stratified sampling of 160 patients). ANCA-positive LN patients had higher chronicity index than ANCA-negative LN patients [3(2, 7) vs 2(0, 5), P=0.006]. There were statistically significant difference in hemoglobin, serum creatinine and estimated glomerular filtration rate among ANCA-positive group, ANCA-negative group, and MPO-ANCA and PR3-ANCA double positive group. MPO-ANCA and PR3-ANCA double positive LN patients had the lowest hemoglobin and estimated glomerular filtration rate, and highest serum creatinine among the three groups (all P<0.05). Conclusions:ANCA-positive LN patients have worse renal function and higher renal histological chronicity index than ANCA-negative LN patients, especially for patients with double positive MPO-ANCA and PR3-ANCA. More stringent monitoring and therapy may be needed in this subgroup of LN patients.

The Prognostic Value of Lymph Node Ratio after Neoadjuvant Chemotherapy in Patients with Locally Advanced Gastric Adenocarcinoma

Purpose@#This study aimed to investigate the prognostic value of lymph node ratio (LNR) in patients with locally advanced gastric cancer who received neoadjuvant chemotherapy. @*Materials and Methods@#We retrospectively enrolled gastric cancer patients treated with neoadjuvant chemotherapy and curative surgery at the First Affiliated Hospital of Zhejiang University from 2004 to 2015 as the study cohort. Patients with the same inclusion criteria treated in 2016–2017 were enrolled as the validation cohort. Kaplan-Meier curves were assessed using the log-rank test to analyze the differences in overall survival (OS).Multivariate survival analysis was performed using the Cox proportional hazards model.The areas under the receiver operating characteristic curve of ypN and LNR categories for predicting the actual 3-year OS were compared. @*Results@#A total of 265 patients were included in the proposal cohort. The median number of retrieved lymph nodes (rLNs) was 32. The number of positive lymph nodes (pLNs) increased as rLN increased (P=0.037), but the LNR remained relatively constant (P=0.462). The LNR was categorized into 4 groups according to the prognosis: ypNr0, node-negative with rLN>25; ypNr1, node-negative with rLN≤25 or 00.3. In the validation cohort of 43 enrolled patients, there was a clear distinction in OS that significantly (P<0.001) varied depending on the LNR values and LNR was the only independent prognostic factor in multivariate analysis (P<0.001). @*Conclusions@#LNR was an independent prognostic factor for survival of patients with gastric cancer after preoperative chemotherapy and might be an alternative predictor for ypN stage.

Analysis of association between segmental glomerulosclerosis and renal function decline in IgA nephropathy / 中华肾脏病杂志

Objective:To explore the relationship between segmental glomerulosclerosis and the change of renal function in IgA nephropathy (IgAN).Methods:It was a single-center retrospective cohort study. The patients with biopsy-proven primary IgAN who were hospitalized in Shenzhen Second People's Hospital from January 1, 2011 to December 31, 2018 were included. Participants with a secondary cause of IgAN, without baseline serum creatinine or renal pathology data for Oxford classification, baseline estimated glomerulofiltration rate (eGFR)<30 ml·min -1·(1.73 m 2) -1, follow-up time<6 months, or less than three times measurements of followed-up serum creatinine were excluded. The clinical data, laboratory tests and renal pathology data and so on were collected. Patients were divided into absence of segmental glomerulosclerosis (S0) group and segmental glomerulosclerosis (S1) group according to the Oxford classification. The generalized additive mixed model was used to analyze the associations of segmental glomerulosclerosis and longitudinal renal function decline (Renal function was evaluated by using the eGFR). Results:There were 280 patients included in this study, with 199 patients in S0 group, and 81 patients in S1 group. Compared with S0 group, patients in S1 group exhibited higher levels of triglyceride, serum uric acid as well as 24-hour urinary protein, and a lower level of eGFR, and had higher proportions of tubular atrophy and interstitial fibrosis (T) (all P<0.05). After adjusting for age, gender, mean arterial pressure, 24-hour urinary protein, mesangial hypercellularity (M), endocapillary hypercellularity (E), T and crescent (C) in the generalized additive mixed model, the effect value of S1 (the difference of baseline eGFR between S1 group and S0 group) was -14.09 ml·min -1·(1.73 m 2) -1. For every additional year, the eGFR of S0 group decreased 1.29 ml·min -1·(1.73 m 2) -1 (95% CI 0.47-2.12, P=0.002) in average, and eGFR decline in S1 group had 2.85 ml·min -1·(1.73 m 2) -1 more than that in S0 group [95% CI 1.05-4.64, P=0.002]. Conclusion:Segmental glomerulosclerosis is independently associated with the longitudinal decrease in renal function in patients with IgAN, which suggests therapies targeted for improving the early damages of segmental glomerulosclerosis may be essential to delay the renal function decline progression.

Paroxysmal nocturnal hemoglobinuria complicated with chronic tubulointerstitial nephritis: a case report and literature review / 中华肾脏病杂志

Objective:To report a rare case of paroxysmal nocturnal hemoglobinuria (PNH) complicated with chronic tubulointerstitial nephropathy, combined with literature review, and discuss the clinical, imaging and pathological characteristics of the disease and the diagnosis and treatment ideas.Methods:The patient's clinical data, magnetic resonance imaging (MRI) and kidney pathological examination results, treatment measures and effects were collected and reported. Through systematic review of relevant literature, the clinical manifestations and pathogenesis of chronic tubular interstitial nephropathy complicated by PNH were summarized and discussed.Results:In this case, PNH was diagnosed for more than 30 years, the peripheral blood PNH clone was positive, urine specific gravity was 1.012, urine pH 6.0-7.0, urine protein (+), urine sugar (3+), serum creatinine 259 μmol/L, serum lactic acid dehydrogenase 800 U/L. MRI showed bilateral renal cortical signal was low intensity on both T1- and T2- weighted images. Kidney biopsy revealed remarkable chronic tubulointerstitial nephropathy with massive hemosiderin deposition in proximal tubular cells demonstrated by Prussian blue staining and electron microscopy. By using low-dose prednisone to control hemolytic attack and other supportive treatments, the patient's renal function has been stabilized for a long time.Conclusions:PNH complicated with chronic tubulointerstitial nephritis is easy to be misdiagnosed due to insidious onset. MRI and kidney histopathological examination are helpful to clarify the diagnosis. Early diagnosis and treatment are helpful to improve the prognosis of such patients.

New UMOD gene mutation: a familial study of juvenile hyperuricemia nephropathy / 中华肾脏病杂志

Objective:To investigate the etiology, clinicopathological changes and genetic variation characteristics of familial juvenile hyperuricemia nephropathy (FJHN) through pedigree investigation and gene test conducted on a patient with FJHN.Methods:Clinical data of the proband family members were collected, routine pathological examination of the proband kidney tissue was conducted, and the expression of the Uromodulin (UMOD) protein in the proband kidney tissue was detected by immunofluorescence staining. Peripheral blood specimens of proband and their relatives were collected, and gene sequencing analysis related to urinary system diseases including UMOD was performed by double-stranded DNA probe gene capture and high-throughput sequencing. Results:Seven family members in the family were involved and the inheritance method was consistent with autosomal dominant inheritance. Among the seven affected individuals only a 3-year-old child didn't show any clinical abnormalities. All of the remaining six patients had hyperuricemia accompanied with renal dysfunction and three of them were end-stage renal disease and two of them died of uremia. Proband renal pathological results showed chronic tubulointerstitial lesions and focal glomerular sclerosis with no obvious deposition of immune complexes. Immunofluorescent staining showed that strong positive signals of UMOD protein accumulated in the tubular epithelial cells, which was very specific and could be used to differentiate FJHN from other interstial nephritis. A total of four patients including the proband were tested and all had found heterozygous mutation c.377G>A of UMOD gene, a new missense mutation located on exon 3. Conclusion:Involved patients in this family present a typical autosomal dominant inheritance pattern, clinically manifested as hyperuricemia with early renal function impairment, renal pathology manifested as non-immune complex-mediated glomerular sclerosis and renal interstitial fibrosis, and there is abnormal accumulation of UMOD protein in renal tubular epithelial cells. Genetic testing shows a new gene locus mutation c.377G>A, confirming the diagnosis of FJHN. Patients with unexplained hyperuricemia and characteristic pathological changes should undergo renal tissue fluorescent staining of UMOD protein, which may be a simple and feasible method to detect the abnormality of UMOD protein.

Active components of fungus Shiraia Bambusiscola can specifically induce BGC823 gastric cancer cell apoptosis

Objective: Gastric cancer is a major health issue worldwide. Using a therapeutic approach, with minor side-effects, is very essential for the treatment of the gastric cancer. Shiraia bambusicola is a parasitic fungus which is widely used in China for curing several diseases with little side-effects. However, the mechanisms are not well understood yet. The aim of this study was to further understand the pharmacological mechanisms of Shiraia bambusicola and investigate whether it can be used for curing gastric cancer

Materials and Methods: In this experimental study, we mainly tested the effect of active components extracted from Shiraia bambusicola on BGC823, A549 and HepG2 cells. We used MTT assay to test cell viability. We also analyzed morphologic changes caused by apoptosis using Hoechst 33342 fluorescence staining, as well as cell cycle status and apoptosis ratio using flow-cytometer. In addition, protein expression level was tested by Western-blotting assay

Results: BGC-823 cell proliferation was specifically inhibited by active components of Shiraia bambusicola. Meanwhile, these active components could induce BGC-823 cells apoptosis and retard the cell cycle in S/G2 phase. We also determined that two critical protein markers cleaved Poly[ADP-ribose] polymerase-1 [PARP-1] and FLICE-inhibitory protein [FLIP], involved in apoptosis process, were regulated by these active components

Conclusion: These data shed light on the treatment of human gastric cancer and conclude that Shiraia bambusicola can be a good therapeutic candidate for treatment of this malignancy

Therapeutic effect of ellagic acid on Candida albicans infect mice models and its antifungal activity in vitro / 中国药理学通报

Aim To investigate the inhibitory effect of ellagic acid( EA) on fungal strains both in vitro and in vivo. Methods The minimal inhibitory concentration ( MIC ) was determined by the NCCLS ( M27-A2 ) standard method in vitro. The therapeutic action was studied using a Candida albicans infect mice model, the survival rate and the content of SOD, MDA in ser-um were measured, and the pathological changes of liver were observed under light microscope after HE staining. Results EA was active against three Candida strains, with MICs between 25. 0 and 75. 0 mg·L-1 . The most sensitive Candida species was C. albicans ( MIC=25. 0 mg·L-1 ) . It was inactive against Can-dida glabrata. An in vivo test demonstrated that intrap-eritoneal injection of EA(40 and 80 mg·kg-1 ) signif-icantly enhanced the pathological changes of liver, im-proved the symptom, increased the weight and the SOD activity, and decreased the MDA activity in a mice in-fection model of C. albicans. Conclusion Ellagic acid has the potential to be developed as a natural antifungal agent.

Diagnosis and Treatment Significance of Invasive and Noninvasive Operation for Ventilator-associated Pneumonia / 沈阳医学院学报

Objective:To investigate the diagnosis and treatment significance of invasive and noninvasive operation for ventilator?as?sociated pneumonia ( VAP ) . Methods:A total of 80 cases of VAP suspected patients who had received mechanical ventilation at least 48 hours in ICU from Jun 2014 to Mar 2015 were enrolled. Patients were randomly divided into four groups including noninvasive operation group ( F) , invasive operation group ( Q) , mix group 1 ( H1) and mix group 2 ( H2) . VAP diagnosis rate between groups as well as living time, antibiotic use time, survival rate, calcitonin levels and APACHE II score, oxygenation index were analyzed. Results:Specimen from invasive operation had higher specimens to cultivate positive rate than that from noninvasive operation ( P<0?05), but there was no statistic significant difference in VAP diagnosis rate between two methods (P>0?05). Conclusion:Noninva?sive operation collecting samples for VAP diagnosis is also accurate as invasive one. Collecting specimens from sputum suction tube in the clinical treatment on airway suction is a low cost and simple noninvasive operation.
