OBJECTIVETo investigate the effect of Compound Qingqin Liquid (CQL) on the expression level of angiotensin II (Ang II) and COX-2 mRNA transcription and protein expression in the renal tissue of rats with uric acid nephropathy.

METHODSSD rats were randomly divided into the blank control group, the model group, the positive drug group, the high, moderate, and low dose CQL group according to number randomization principle. The model was established by gastrogavage of adenine, accompanied with yeast feeding. Distilled water was given by gastrogavage to rats in the blank control group and the model group. Allopurinol at the daily dose of 9.33 mg/kg was given by gastrogavage to rats of the positive control group. CQL at the daily dose of 3.77 g/kg, 1.89 g/kg, and 0.09 g/kg was respectively given by gastrogavage to rats in the high, moderate, and low dose CQL groups. All treatment lasted for 6 weeks. Rats were randomly divided at week 4 (3 in the blank control group, and 6 in the rest groups), and the rest rats were killed at week 6. The renal tissue was extracted. The expression level of Ang II and COX-2 mRNA transcription were detected by RT-PCR. The expression level of Ang II was detected by ELISA. The expression level of COX-2 protein was detected by Western blot and immunohistochemical assay.

RESULTSCompared with the blank control group, except the mRNA expression of Ang II at week 4, the mRNA and protein expression of Ang II and COX-2 obviously increased at week 4 and 6 in the model group (P < 0.01, P < 0.05). The COX-2 protein expression at week 4 was obviously lower in the high and moderate dose CQL groups than in the model group and the low dose CQL group (P < 0.05); the average integral of optical density value was obviously lower in the positive control group than in the model group. Except the mRNA expression of Ang II in the high dose CQL group at week 6, the mRNA and protein expression of Ang II obviously decreased in the positive control group and each dose CQL group (P < 0.01, P < 0.05). Of them, the effects were better in the high and moderate dose CQL groups than in the positive control group and the low dose CQL group (P < 0.05, P < 0.01). Besides, the mRNA expression of COX-2, the average integral of optical density value were obviously lower in the positive control group and each dose CQL group than in the model group (P < 0.05). The protein expression of COX-2 was obviously lower in the high and moderate dose CQL groups than in the model group (P < 0.05). Of them, the mRNA expression of COX-2 was better in the moderate dose CQL group than in the positive control group (P < 0.05); the protein expression of COX-2 was better in the high dose CQL group than in the low dose CQL group (P < 0.05).

CONCLUSIONCQL was capable of lowering the expression level of Ang II, COX-2 mRNA transcription and protein expression, thus suppressing the inflammatory pathological injury of the renal tissue.

OBJECTIVETo investigate the effect of compound qingqin liquid (CQL) on Toll-like receptor 2 (TLR2) and toll-like receptor 4 (TLR4) in rats with urate nephropathy, and to explore its renal protection mechanism.

METHODSTotally 55 SD rats were randomly divided into 5 groups, i.e., the normal control group (n =5), the model group (n =10), the positive drug group (n=10), and the high-, medium-, low-dose CQL groups (n=10) respectively. The urate nephropathy model was induced by intragastrically administering adenine and feeding yeast. Distilled water was intragastrically administered at the daily dose of 10 mL/kg to rats in the normal control group and the model group. Allopurinol was intragastrically administered at the daily dose of 9.33 mg/kg to rats in the positive control group. CQL was intragastrically administered at the daily dose of 3.77, 1.89, 0.94 g/kg to rats in the high-, medium-, and low-dose CQL groups. Rats of each group were executed in batches at the 4th and 6th week respectively. Their kidney tissues were taken out to determine the mRNA transcription level of TLR2 and TLR4 by reverse transcription-polymerase chain reaction (RT-PCR). The protein expression level of TLR2 and TLR4 were determined by Western blot. The protein expression level of TLR4 was also detected by immunohistochemical assay.

RESULTSAt week 4 and 6, the protein expression of TLR2 and TLR4 as well as the mRNA transcription of TLR4 increased in the model group, when compared with the control group (P < 0.05, P < 0.01). Compared with the model group, there was no statistical difference in the transcription level of TLR2 mRNA or TLR4 mRNA among the 3 CQL groups (P > 0.05) at week 4 and 6. Additionally, at week 6, the protein expression of TLR4 and TLR2 could be reduced by CQL (P < 0.05, P < 0.01).

CONCLUSIONCQL might protect kidney tissue against inflammatory injury by inhibiting the protein expression levels of TLR2 and TLR4.

OBJECTIVETo analyze the clinical features and prognostic factors of primary gastric diffuse large B-cell lymphoma (PG-DLBCL) and to evaluate the staging system and treatment modality of PG-DLBCL.

METHODSThe clinicopathological data of 69 patients with PG-DLBCL were retrospectively analyzed. Event-free survival (EFS) and overall survival (OS) were the primary endpoints.

RESULTSThe EFS rates at 1, 3, and 5 years were 83.8%, 71.1%, and 69.0%, respectively, with a mean EFS of 91.3 months. The 1-, 3-, and 5-year OS rates were 91.3%, 80.3%, and 72.4%, respectively, with a mean OS of 98.8 months. Univariate analysis revealed that either EFS or OS was significantly prolonged by the following factors (P < 0.05): modified Ann Arbor stage I(E) or II(E1) disease; normal lactate dehydrogenase (LDH) level; normal hemoglobin level; normal albumin level; International Prognostic Index (IPI) of 0 or 1; tumor size < 5 cm; and less depth of invasion. While gender, age, B symptoms at presentation, performance status and treatment modality were not significantly associated with the prognosis (P > 0.05). Cox regression model revealed that only modified Ann Arbor stage and albumin level were independent prognostic factors for EFS and OS.

CONCLUSIONThe most accurate staging system and the exact role of different therapeutic options for PG-DLBCL are still debated. Further randomized prospective studies with a large number of patients are still needed to establish an optimal management for this disease.

BACKGROUNDThe perioperative aortic dissection (AD) rupture is a severe event after endovascular stent graft placement for treatment of type B AD. However, this life-threatening complication has not undergone systematic investigation. The aim of the study is to discuss the reasons of AD rupture after the procedure.

METHODSThe medical record data of 563 Stanford type B AD patients who received thoracic endovascular repair from 2004 to December 2011 at our institution were collected and analyzed. Double entry and consistency checking were performed with Epidata software.

RESULTSTwelve patients died during the perioperation after thoracic endovascular repair, with an incidence of 2.1%, 66.6% were caused by aortic rupture and half of the aortic rupture deaths were caused by retrograde type A AD. In our study, 74% of the non-rupture surviving patients had the free-flow bare spring proximal stent implanted, compared with 100% of the aortic rupture patients (74% vs. 100%, P = 0.213). The aortic rupture patients are more likely to have ascending aortic diameters = 4 cm (62.5% vs. 9.0%, P = 0.032), involvement the aortic arch concavity (62% vs. 27%, P = 0.041) and have had multiple stents placed (P = 0.039).

CONCLUSIONSThoracic AD endovascular repair is a safe and effective treatment option for AD with relative low in-hospital mortality. AD rupture may be more common in arch stent-graft patients with an ascending aortic diameter = 4 cm and with severe dissection that needs multi-stent placement. Attention should be paid to a proximal bare spring stent that has a higher probability of inducing an AD rupture. Post balloon dilation should be performed with serious caution, particularly for the migration during dilation.

The global metabolite profiles of endogenous compounds of Wistar rats from 12 to 20 weeks old were investigated to take deep insight into and get better understanding of the pathogenesis of development and aging. Plasma from Wistar rats at 12, 14, 16, 18, and 20 weeks old were analyzed using GC/TOFMS. Multivariate data analysis was then used to process the metabonomic data which indicated excellent separation between different weeks and showed that the metabolic profiles of the samples changed with age, enabling age-related metabolic trajectories to be visualized. Decreased concentrations of citric acid, cis-aconitic acid, 9-(z)-hexadecenoic acid along with increased levels of hexanedioic acid, alpha-tocopherol, 3-indole propionic acid, etc contributed to the separation. Several major metabolic pathways were identified to be involved in metabolic regulation. This suggests that GC/TOFMS-based metabonomics is a powerful alternative approach to identifying potential biomarkers and investigating the physiological developments of aging and it is important to employ suitable age-match control group in metabonomic study of physiological monitoring, drug safety assessment, and disease diagnosis, etc.

OBJECTIVETo study the benefit of prophylactic antibiotics (PA) in totally percutaneous aortic endovascular repair (PEVAR) in the catheterization laboratory for reducing stent-graft infection and postimplantation syndrome (PIS).

METHODSThe clinical data were analyzed of patients undergoing thoracic endovascular aortic repairs. The patients were divided into non-PA group and PA group according to the use of prophylactic antibiotics before PEVAR. The diagnosis of infection was made by two senior physicians with reference to Hospital Acquired Infection Diagnostic Criteria Assessment released by the Ministry of Health of China.

RESULTSThe 95 enrolled patients included 35 with PA and 60 without PA group, who were comparable for baseline characteristics. Infection-related deaths occurred in 1 case in non-PA group and retrograde Stanford type A dissection and death occurred in 1 case in PA group (1.67% vs 2.85%, P=1.00). The PA and non-PA groups showed no significant difference in the incidence of postoperative infection (5% vs 2.86%, P=1.000), hospital stay (9.30±7.21 vs 10.06±5.69, P=0.094), infection-related mortality (1.67% vs 0%, P=1.00), or postoperative fever (70.90% vs 91.43%, P=0.20). The body temperature showed significant variations at different time points after procedure (F=19.831, P<0.001) irrelevant to the use of prophylactic antibiotics (F=0.978, P=0.326).

CONCLUSIONThe current data do not support the benefit of PA in reducing postoperative infection and PIS in patients undergoing PEVAR, but the patients without PA may have worse clinical outcomes in the event of postoperative infections.

Objective:To study the predictive value of total serum bilirubin (TSB) and the ratio of bilirubin to albumin (B/A) in neonatal acute bilirubin encephalopathy (ABE).Methods:Neonates with extremely severe hyperbilirubinemia (TSB≥425 μmol/L) treated in the Nanjing Maternal and Child Health Hospital, Maternity and Child Health Care of Guangxi Zhuang Autonomous Region, Northwest Women and Children's Hospital, Yinchuan Maternal and Child Health Hospital and Liaocheng People's Hospital from March 2018 to August 2019 were selected as prospective subjects for this study. According to the score of brain injury induced by bilirubin, the subjects were divided into ABE group and non-ABE group, and the predictive value of TSB peak and B/A for neonatal ABE were analyzed.Results:A total of 194 infants with extremely severe hyperbilirubinemia were recruited in this study, including 20 in ABE group and 174 in non-ABE group. The peak value of bilirubin ranged from 427 to 979 μmol/L. The optimal critical values of TSB peak value and B/A for ABE prediction were 530 μmol/L and 9.48, respectively. The sensitivity and specificity of ABE prediction were 85.0% and 92.8% when combined with TSB peak and B/A values.Conclusions:TSB peak combined with B/A value can effectively identify neonatal ABE. When the TSB peak value was greater than 530 μmol/L and the B/A value was greater than 9.48, the neonates had a higher risk of neonatal ABE.

This study aims to observe the effect of chlorogenic acid(CGA) on microRNA(miRNA) in the process of protecting against N-acetyl-p-aminophenol(APAP)-induced liver injury. Eighteen C57BL/6 mice were randomly assigned into a normal group, a model group(APAP, 300 mg·kg~(-1)), and a CGA(40 mg·kg~(-1)) group. Hepatotoxicity of mice was induced by intragastric administration of APAP(300 mg·kg~(-1)). The mice in the CGA group were administrated with CGA(40 mg·kg~(-1)) by gavage 1 h after APAP administration. The mice were sacrificed 6 h after APAP administration, and plasma and liver tissue samples were collected for the determination of serum alanine/aspartate aminotransferase(ALT/AST) level and observation of liver histopathology, respectively. MiRNA array combined with real-time PCR was employed to discover important miRNAs. The target genes of miRNAs were predicted via miRWalk and TargetScan 7.2, verified by real-time PCR, and then subjected to functional annotation and signaling pathway enrichment. The results showed that CGA administration lowered the serum ALT/AST level elevated by APAP and alleviate the liver injury. Nine potential miRNAs were screened out from the microarray. The expression of miR-2137 and miR-451a in the liver tissue was verified by real-time PCR. The expression of miR-2137 and miR-451a was significantly up-regulated after APAP administration, and such up-regulated expression was significantly down-regulated after CGA administration, consistent with the array results. The target genes of miR-2137 and miR-451a were predicted and verified. Eleven target genes were involved in the process of CGA protecting against APAP-induced liver injury. Gene Ontology(GO) annotation and Kyoto Encyclopedia of Genes and Genomes(KEGG) enrichment with DAVID and R language showed that the 11 target genes were enriched in Rho protein-related signal transduction, vascular patterning-related biological processes, binding to transcription factors, and Rho guanyl-nucleotide exchange factor activity. The results indicated that miR-2137 and miR-451a played an important role in the inhibition of CGA on APAP-induced hepatotoxicity.
