We retrospectively analyzed the clinical data of seven patients (four men and three women) with primary hyperoxaluria (PH) type 1 (PH1) in the Department of Nephrology of Zhongda Hospital, Southeast University from January 2018 to October 2023. The mean age at disease onset was 32.1 (range: 26-42) years. The mean age at diagnosis was 40.6 (range: 28-51) years. All patients initially had kidney stones, and three patients were found to have renal insufficiency at the time of disease onset. Among them, two patients underwent hemodialysis immediately. Symptoms at the first visit included bone pain ( n=7), joint pain or deformity ( n=5), fatigue ( n=5), hypotension ( n=3), and subcutaneous nodules ( n=2). Four patients had a family history of PH. All patients had varying degrees of anemia (60-114 g/L), significant hypoalbuminemia (16.5-32.1 g/L), and hypercoagulable state (D-dimer: 2 230-12 781 μg/L). Seven patients received maintenance hemodialysis; their mean age was 37.7 (range: 26-50) years. The mean duration from disease onset to hemodialysis was 5.6 (range: 0-20) years. Five patients repeatedly experienced dialysis access dysfunction. Three patients underwent kidney transplantation before a diagnosis was made, and all transplanted kidneys lost function due to oxalate deposition. The mean follow-up duration was 14.43 (range: 4-38) months. Unfortunately, one patient died. All seven patients underwent computed tomography of the abdomen. All patients suffered skeletal abnormalities, bilateral nephrolithiasis, and nephrocalcinosis. Six patients carried AGXT gene mutations, including four compound heterozygous mutations and two pure homozygous mutations.The mutation sites included: c.823-824dup.AG (p.S275Rfs*38)(exon 8), c.815-816ins.GA (p.S275Rfs*38)(exon 8), c.595G>A (p.G199S) (exon 5), c.32C>G (p.P11R) (exon 1), and c.638C>T (p.A213V)(exon 6). According to the American College of Medical Genetics and Genomics guidelines, two loci were identified as likely pathogenic variants, seven were identified as pathogenic variants, and one locus was identified as having uncertain significance. In addition, patients 1 and 4 underwent skin biopsy, patient 2 underwent renal transplant biopsy, and patient 3 underwent bone marrow biopsy. Interestingly, significant oxalate deposition was found in the tissues. Therefore, PH1 is a rare autosomal recessive inherited disease. This study not only enhanced the understanding of the clinical characteristics of PH1 patients but also had great significance in early diagnosis and treatment of the disease.

OBJECTIVE To establish a quantitative analysis of multi-components by single marker (QAMS) method based on a variety of internal reference substances for the content determination of 6 components in Jinlian qingre granules, such as mangiferin, 2″-O-β-L-galactopyranosylorientin, orientin, veratric acid, vitexin, harpagoside. METHODS The determination was performed on Agilent Eclipse Plus C18 column with mobile phase consisted of acetonitrile-0.1% phosphoric acid solution (gradient elution) at the flow rate of 1 mL/min. The column temperature was 30 ℃, and the detection wavelength was set at 270 nm. Taking orientin, vitexin and 2″-O-β-L-galactopyranosylorientin as internal references, the relative correction factors (RCF) of the other 5 components to be determined and internal substances were determined by QAMS. The contents of 6 components in 21 batches of Jinlian qingre granules were calculated and then compared with the results of the external standard method. RESULTS The contents of mangiferin, 2″-O-β-L-galactopyranosylorientin, orientin, veratric acid, vitexin and harpagoside in 21 batches of samples were determined by QAMS in the range of 0.234-0.516, 1.804-2.270, 2.143-2.606, 0.190-0.223, 0.594-0.782, 0.080-0.152 mg/g; the contents of them determined by external standard method were 0.235-0.523, 1.798-2.265, 2.137-2.599, 0.190-0.224, 0.597-0.786, 0.077-0.151 mg/g, respectively. The percentage difference between the results measured by the two methods should not exceed 4.00%. CONCLUSIONS QAMS has been constructed for the simultaneous determination of 6 components in Jinlian qingre granules based on a variety of internal reference substances. The results obtained by this method are not significantly different from those obtained by the external standard method, and can be used for the quality control of Jinlian qingre granules.

Chinese Critical Care Medicine 2017;29(12):1107-1111
Objective To investigate the effects of cardiopulmonary bypass (CPB) on the differentiation of T lymphocyte subsets and the expression of specific transcription regulator T-bet/GATA binding protein 3 (GATA3). Methods A prospective double-blind study was conducted. Patients with CPB pulmonary repair of ventricular septal defect (observation group) or off-pump ligation of ductus arteriosus (control group) with 20 cases each in the 150th Military Hospital from February 2015 to February 2016 were enrolled. The blood sampled was collected on the time of before operation, at the end of CPB or operation, 4 hours after operation, and 24 hours after operation. T lymphocytes were isolated, the helper T cell 1 (Th1) specific transcription factor T-bet mRNA, helper T cell 2 (Th2) specific transcription factor GATA3 mRNA expression and cytokine γ-interferon (IFN-γ) mRNA, interleukin-4 (IL-4) mRNA expression were measured by Northern Blot. Results Compared with before operation, expression levels of T-bet mRNA [integral gray values: (1.39±0.52)×105vs. (2.92±0.88)×105], IFN-γ mRNA [integral gray values: (3.68±0.65)×105vs. (6.10±0.93)×105] were decreased transiently at the end of CPB in the observation group (both P < 0.05), returned to preoperative levels at 24 hours after operation [integral gray values: (2.77±0.74)×105, (6.22±1.25)×105, respectively, both P > 0.05]; expression levels of GATA3 mRNA [integral gray values:(4.96±0.88)×105vs. (3.21±0.68)×105], IL-4 mRNA [integral gray values: (3.52±1.13)×105vs. (1.85±0.63)×105] were increased (both P < 0.05), recovered to the preoperative levels at 24 hours after operation [integral gray values: (3.11±0.51)×105, (1.93±0.84)×105, respectively, both P > 0.05]. There were no significant differences in the expressions of T-bet, GATA3, IFN-γ and IL-4 mRNA in the control group at each time points (all P >0.05). Conclusions CPB causes the imbalance of Th1, Tc1/Th2, Tc2 and pro-inflammatory and anti-inflammatory reactions specially, which participate the complication occurrence after CPB. The changing of T-bet/GATA3 may be the internal mechanism for these changes.

Objective To investigate the potential role of CXC chemokine ligand 16 (CXCL16)/CXC chemokine receptor 6 (CXCR6) pathway in the progression of diabetic nephropathy (DN). Methods 8?week old male db/db mice were randomly divided into DN group and DN inflamed group. 10% casein was subcutaneously injected to induce the DN mouse model with inflammation. In vitro, HK?2 cells were treated with high glucose (HG), and IL?1β+HG to investigate the effect of inflammatory stress on HK?2 cells. Further knockdown CXCL16 was mediated by RNA interference to determine the effects of CXCl16, then cells were divided into HG+IL?1βgroup, HG+IL?1β + siCXCL16 group and HG + IL?1β + vehicle group. Changes of renal function in mice were assessed by 24 h proteinuria and N?acetyl?β?D?glucosaminidase (NAG) during 8 weeks. The ultra?microstructure was checked by electron microscopy at 8th week. Lipid accumulation in kidneys and HK?2 were observed by Filipin staining and quantitative assay of intracellular free cholesterol. The protein expressions of CXCl16, CXCR6, a disintegrin and metalloproteinase?10 (ADAM10), fibronectin and α smooth muscle actin (α?SMA) in renal tissue were detected by immunohistochemistry and Western blotting. The mRNA and protein expressions of CXCl16, CXCR6, ADAM10, fibronectin andα?SMA in HK?2 cells were detected by real?time PCR and Western blotting, and protein expressions of CXCl16, CXCR6 and ADAM10 in HK?2 cells were also tested by cell immunofluorescence. Results Mice in DN inflamed group had higher 24 h proteinuria and NAG than those in DN group, and the differences between two groups shown statistical significance at 8th week (all P<0.05). Compared with DN mice, DN inflamed mice had more vacuoles within renal tubular cells, with mitochondrial swelling, deformation and decrease. Lipid accumulation and protein expressions of fibronectin and α?SMA were increased in DN inflamed group when compared with DN group (all P<0.05). Further, the expressions of CXCL16, CXCR6, ADAM10 were significantly increased in DN inflamed group (all P<0.05). In vitro, the mRNA and protein expressions of CXCL16, CXCR6, ADAM10, fibronectin and α?SMA, and lipid accumulation were increased in high glucose plus IL?1βgroup when compared with high glucose group (all P<0.05). However, after siRNA of CXCL16 transfection, the mRNA and protein expressions of CXCL16, CXCR6, ADAM10, fibronectin andα?SMA were down?regulated in HG+IL?1β+siCXCL16 group as compared with high glucose+IL?1βgroup (all P<0.05). Furthermore, lipid accumulation was decreased (P<0.05). Conclusion Inflammation accelerates tubulointerstitial injury in DN partly through the activation of CXCL16 pathway, which may facilitate the lipid accumulation in tubular epithelial cells.
