Tuberculosis (TB) is still a major public health issue today. A novel TB vaccine is a key approach to reaching the targets of WHO's End-TB Strategy. In recent years, significant progress has been made in the research and development of TB vaccines both in China and abroad. A breakthrough has been made in both application scenarios and technological routes, and several vaccine candidates have entered phase Ⅲ clinical trials. This review summarizes information from clinical trials involving key TB vaccine candidates under development in China and abroad. It highlights six candidates that are most promising for marketing or inspiring future research and development, analyzes the current difficulties in the research and development of novel TB vaccines, and provides an outlook for the future.

Objective To investigate the renal function recovery and perioperative risk factors for chronic kidney disease in patients after acute Stanford type A aortic dissection (ATAAD) repair. Methods A retrospective study was conducted on patients who underwent ATAAD repair at the Xiamen Cardiovascular Hospital, Xiamen University from 2020 to 2021, and their clinical data were analyzed. Results A total of 255 patients were included, with 200 males and 55 females, and an average age of (52.80±12.46) years. The incidence of acute kidney injury (AKI) after ATAAD repair was 43.9%. Dissection involving the renal artery [OR=2.144, 95%CI (1.234, 3.765), P=0.007], intraoperative urine output [OR=0.761, 95%CI (0.625, 0.911), P=0.004], and intraoperative red blood cell transfusion [OR=1.288, 95%CI (1.088, 1.543), P=0.004] were significantly associated with early AKI after ATAAD repair. Long-term renal function follow-up data were available for 232 patients, among whom 40 (17.2%) patients developed chronic kidney disease (CKD). Independent predictors for CKD included lower body mass index [OR=0.827, 95%CI (0.723, 0.931), P=0.003], preoperative cardiac tamponade [OR=5.344, 95%CI (1.65, 17.958), P=0.005], preoperative renal hypoperfusion syndrome [OR=12.629, 95%CI (5.003, 35.373), P<0.001], postoperative peak serum creatinine time>3 d [OR=7.566, 95%CI (2.799, 22.731), P<0.001], and AKI grade [grade 1: OR=4.418, 95%CI (1.339, 15.361), P=0.016; grade 2: OR=8.345, 95%CI (1.762, 40.499), P=0.007; grade 3: OR=9.463, 95%CI (2.602, 37.693), P<0.001]. Conclusion AKI related to ATAAD repair can recover in the early postoperative period, but both the duration and severity of AKI will affect long-term renal function. In addition, patients' nutritional status, preoperative cardiac tamponade, and renal hypoperfusion syndrome are also independent risk factors for long-term renal dysfunction.

Objective To investigate the expression of urinary galectin-3 binding protein(Gal-3BP)and V-set containing immunoglobulin domain 4(VSIG4)in urine from patient with systemic lupus erythematosus(SLE)and its relationship with disease activity and kidney injury.Methods A total of 105 SLE patients(SLE group)and 50 normal patients(control group)admitted to Danzhou People's Hospital were selected as the study objects.According to SLEDAI score,105 SLE patients were divided into mild active group(SLEDAI≤9 points,n=51),moderate active group(14 point≥SLEDAI≥10 points,n=29)and severe active group(SLEDAI ≥ 15 points,n=25).According to the degree of renal function impairment,they were divided into normal renal function group,mild renal function impairment group and moderate and severe renal function impairment group.Enzyme linked immunosorbent assay was used to detect the expressions of Gal-3BP and VSIG4.Multiple Logistic regression was applied to analyze the risk factors of kidney injury in SLE patients,and ROC curve was drawn to analyze the value of urinary Gal-3BP and VSIG4 levels in predicting kidney injury in SLE patients.Results The urinary Gal-3BP(251.38±46.75 ng/ml)and VSIG4(13.40±4.27 ng/ml)levels in the SLE group were higher than those in the control group(117.50±18.24 ng/ml,2.73±0.85ng/ml),and the differences were statistically significant(t=19.315,15.681,all P＜0.001).The higher the activity level of SLE patients,the higher the urinary Gal-3BP and VSIG4 levels,with severe activity group＞moderate activity group＞mild activity group,and the differences were statistically significant(F=23.416,17.380,all P＜0.001).The urinary Gal-3BP and VSIG4 levels in the moderate to severe renal function group and mild renal function group were higher than those in the normal renal function group(t=24.580,18.163,20.864,15.947),and the urinary Gal-3BP and VSIG4 levels in the moderate to severe renal function group were higher than those in the mild renal function group(t=19.837,11.215),and the differences were statistically significant(all P＜0.001),respectively.Multiple logistic regression analysis showed that elevated levels of urinary Gal-3BP(OR=3.472,95％CI:2.685～11.463)and VSIG4(OR=2.376,95％CI:1.842～9.105)were risk factors for renal injury in SLE patients(all P＜0.05).ROC curve analysis showed that the combination of Gal-3BP and VSIG4 had the highest area under the curve(95％confidence interval)[AUC(95％CI)]for predicting renal injury in SLE patients[0.909(0.846～0.973)],with an accuracy of 88.6％.Correlation analysis showed that the urinary Gal-3BP level was positively correlated with VSIG4 level(r=0.813,P＜0.05),and the levels of urinary Gal-3BP and VSIG4 were positively correlated with SCr,BUN,24-hour urine protein,anti-dsDNA antibodies,and SLEDAI scores(r=0.358～0.702,all P＜0.05),while urinary Gal-3BP and VS1G4 levels were negatively correlated with hemoglobin and eGFR in SLE patients(r=-0.479～-0.670,all P＜0.05).Conclusion Urinary Gal-3BP and VSIG4 levels are elevated in SLE patients,and their high expressions are related to disease activity and renal injury.The combination of the two have good value in predicting renal injury in SLE patients.

OBJECTIVE To explore the improvement mechanism of proanthocyanidins on acute kidney injury （AKI） induced by gentamicin in rats. METHODS Gentamicin sulfate was injected intraperitoneally to construct the AKI rat model； the model rats were randomly divided into model control group， benazepril hydrochloride 5 mg/kg group （positive control）， proanthocyanidins 50 mg/kg group， proanthocyanidins 100 mg/kg group， and proanthocyanidins 200 mg/kg group， with 10 rats in each group； in addition， 10 normal rats were selected to be treated as the normal control group. The rats in each administration group were given corresponding liquid intragastrically， and the normal control group and model control group were given equal volumes of normal saline intragastrically， once a day， for 28 consecutive days. After the last administration， the levels of serum creatinine （SCr）， blood urea nitrogen （BUN）， malondialdehyde （MDA）， superoxide dismutase （SOD）， glutathione peroxidase （GSH-Px） and 24 h urinary protein （UP） were detected； the renal index was calculated； the pathological changes of renal tissue were observed and the pathological score was calculated； the apoptotic rate of cells in renal tissue and the expression levels of Caspase-3 and Bcl-2 associated X protein （Bax）， as well as the phosphorylation levels of silent information regulator of transcription 1 （SIRT1） and AMP-activated protein kinase （AMPK） were detected. RESULTS Compared with the model control group， the levels of SCr， BUN， UP and MDA， the renal index， the pathological score of renal tissue， the apoptotic rate of cells in renal tissue， the protein expression levels of Caspase-3 and Bax in renal tissue of rats in each administration group were decreased significantly； SOD and GSH-Px levels， phosphorylation levels of SIRT1 and AMPK protein were increased significantly （P＜0.05）， and the effect of proanthocyanidins was in a dose-dependent manner （P＜0.05）. There were no significant differences in the above indexes between proanthocyanidins 200 mg/kg group and benazepril hydrochloride 5 mg/kg group （P＞0.05）. CONCLUSIONS The improvement effect of proanthocyanidins on AKI rats may be related to the activation of SIRT1/AMPK signaling pathway to inhibit oxidative stress.
