Objective:To explore the relationship between glycosylated hemoglobin A 1c/high-density lipoprotein cholesterol ratio (HbA 1c/HDL-C) and urinary albumin-creatinine ratio (UACR) in Chinese adults. Methods:In this cross-sectional study, the clinical data of 43 820 community residents (age>40 years) from the Risk Evaluation of Cancers in Chinese Diabetic Individuals (REACTION study; March-December 2012) across eight centers (Liaoning, Guangdong, Shanghai, Gansu, Guangxi, Henan, Hubei, and Sichuan) in China were collected and analyzed. Participants were divided into three groups based on UACR levels:<10 mg/g, 10-30 mg/g, and >30 mg/g. The HbA 1c/HDL-C ratio was divided into four groups according to quartile division of the subjects: 1st quartile (Q1<3.79), 2nd quartile (3.79≤Q2<4.59), 3rd quartile (4.59≤Q3≤5.66), and 4th quartile (Q4>5.66). Multivariate ordinal logistic regression model was used to analyze the relationship between HbA 1c/HDL-C and UACR. Receiver operating characteristic (ROC) analysis was used to explore the predictive value of HbA 1c/HDL-C to UACR. Results:The 43 820 subjects included 13 452 (30.70%) male and 30 378 (69.30%) female patients, with an average age of (58.00±0.05) years. According to results of one-way analysis of variance analysis, the HbA 1c/HDL-C ratio was significantly associated with the risk of increased UACR ( F=495.73, P<0.001). After adjusting for clinically relevant confounding variables in logistic regression model, compared with participants with the lowest HbA 1c/HDL-C ratio (Q1), women with the highest HbA 1c/HDL-C ratio (Q4) had a 1.483-fold (95% CI 1.376-1.598, P<0.001) and men had a 1.161-fold (95% CI 1.019-1.323, P<0.001) increased risk of UACR. The ROC curve analysis showed that the area under the curve of HbA 1c/HDL-C for predicting increased UACR was 0.623 (95% CI 0.597-0.606), with a sensitivity of 60.18% and a specificity of 54.91%. The HbA 1c/HDL-C ratio showed the highest predictive value of all glycemic and lipidemic parameters. In individuals with well-controlled blood glucose (HbA 1c<6.5%) or lipid levels (HDL-C≥1.0 mmol/L), the HbA 1c/HDL-C ratio was still independently associated with the risk of increased UACR after adjusting for confounding variables [ OR(95% CI) of quartile 4: 1.563 (1.210-2.019, P=0.001) in participants with HbA 1c<6.5% and 1.822 (1.687-1.968, P<0.001) in participants with HDL-C≥1.0 mmol/L]. Conclusion:As a novel compound indicator for evaluating glucose homeostasis and dyslipidemia, the HbA 1c/HDL-C ratio was independently associated with increased UACR in the general population aged>40 years in China, which was superior to both glycemic and lipid parameters alone.

Objective:To investigate the efficacy of different treatment modes for locoregional recurrence after nephrectomy in patients with renal cell carcinoma.Methods:A total of 106 patients with locoregional recurrence after nephrectomy without distant metastasis (77 males and 29 females) admitted to Sun Yat-sen University Cancer Center from October 2001 to July 2020 were retrospectively analyzed. The median age was 51 (40, 60) years old. Radical nephrectomy was performed in 90 patients with primary tumor and partial nephrectomy was performed in 16 patients. Pathological diagnosis showed that 54 cases were clear cell carcinoma and 52 cases were non-clear cell carcinoma. 53 cases were in stage T 1-2 and 53 cases in stage T 3-4. The median diameter of recurrent lesions was 3.2 (2.0, 6.3) cm, and the median number was 2 (1, 4). The recurrence sites were divided into renal fossa recurrence (33 cases), renal fossa±retroperitoneal lymph node recurrence (38 cases), and intra-abdominal spread (35 cases). The median duration from primary surgery to local recurrence was 14.8 (7.3, 35.8) months. Two treatment groups were identified as systemic therapy alone (Group A) and local therapy with or without systemic therapy (Group B). The Kaplan-Meier method was used to compare the progression free survival (PFS) and overall survival (OS) between Group A and Group B. The Cox model was used to perform univariate and multivariate analysis. Results:Of all the 106 patients, 33 patients were in Group A and 73 patients were in Group B. In Group A, 29 patients (87.9%) received targeted therapy, and 4 patients (12.1%) received targeted therapy combined with immunotherapy. In Group B, 34 patients (46.6%) received surgery or ablation and 39 patients (53.4%) received SBRT, of which 62 patients (84.9%) received concurrent systemic therapy. Among them, 58 patients (93.5%) received targeted therapy, and 4 patients (6.5%) received targeted therapy combined with immunotherapy. The median follow-up period was 29.0 (15.4, 45.9) months, 64 patients progressed on tumor including 28 patients died. The median PFS and OS were 15.6 (7.1, 35.2) months and 66.9 (37.8, not reached) months. The median PFS of Group A and Group B were 7.6(5.0, 17.2)months and 22.2(9.6, 63.9)months respectively ( P=0.001), median OS of Group A and Group B were 45.7 (23.4, 62.8)months and 71.0(50.6, not reached)months respectively, and the 2-year OS were 70.6% and 85.5% in Group A and Group B respectively ( P=0.023). The univariate analysis showed local therapy with or without systemic therapy was significantly reduced 56% risk of tumor progression ( HR=0.44, P=0.003) and reduced 60% risk of death ( HR=0.40, P=0.028). The multivariate analysis showed that the OS was associated with ECOG score( HR=10.20, 95% CI 4.13-25.30, P<0.001)and local therapy( HR=0.23, 95% CI 0.09-0.58, P=0.002). Conclusion:Compared with systemic therapy alone, local therapy with or without systemic therapy can effectively improve the PFS and OS of patients with locoregional recurrence after nephrectomy.

Objective To investigate the application prospect of the most extensive genome engineering pig internationally in preclinical xenotransplantation. Methods Porcine endogenous retrovirus (PERV) knockout combined with 3 major heterologous antigen gene knockouts and 9 humanized genes for inhibition of complement activation, regulation of coagulation disorders, anti-inflammatory and anti-phagocytosis were transferred into a pig (PERV-KO/3-KO/9-TG) as a donor, and the heart, liver and kidney were obtained and transplanted to 3 Rhesus macaque recipients respectively to establish a preclinical research model of pig-to-Rhesus macaque xenotransplantation. The functional status of xenografts after blood flow reconstruction was observed and the survival of recipients was summarized. The hemodynamics of xenografts were monitored. The change of hematological indexes of each recipient was compared. The histopathological manifestation of xenografts was observed. Results After the blood flow was reconstructed, all xenografts showed ruddy color, soft texture and good perfusion. The transplant heart, liver and kidney showed full arterial and venous blood flow and good perfusion at 1 d after operation. The postoperative survival time of heart, liver, and kidney transplant recipients was 7, 26, and 1 d, respectively. The levels of creatine kinase, creatine kinase isoenzyme, and lactate dehydrogenase increased in heart transplant recipient at 1 d after operation, and gradually recovered to near normal levels at 6 d after operation. All indexes increased sharply at 7 d after operation. The level of aspartate aminotransferase increased in liver transplant recipients at 2 d after operation, and the alanine aminotransferase basically returned to normal at 10 d after operation, but the total bilirubin continued to increase. Both aspartate aminotransferase and alanine aminotransferase increased at 12 d after operation, and reached a peak at 15 d after operation. The kidney transplant recipient developed mild proteinuria at 1 d after operation, and died of sudden severe arrhythmia. Histopathology showed that the tissue structure of cardiac and renal xenografts was close to normal, and liver xenografts presented with patchy necrosis, the liver tissue structure was disordered, accompanied by inflammatory damage, interstitial hemorrhage and thrombotic microangiopathy. Conclusions PERV-KO/3-KO/9-TG pig shows advantages in overcoming hyperacute rejection, mitigating humoral rejection and coagulation dysregulation. However, whether it can be used as potential donor for clinical xenotransplantation needs further evaluation.

Objective: To report the experience on the multi-disciplinary management of metastatic renal cell (mRCC) patients in a single center. Methods: Data of 168 mRCC patients treated by multi-disciplinary team (MDT) at Sun Yat-sen University Cancer Center from December 2007 to February 2019 was retrospectively analyzed.Three treatment groups were identified, including 76 patients with 55 males and 21 females, received anti-angiogenic agents alone (Group A), 66 patients with 55 males and 11 males, received anti-angiogenic agents plus local therapy (Group B)and 26 patients, with 19 males and 7 females, received anti-angiogenic agents plus immunotherapy and local therapy (Group C). The Sunitinib, Sorafenib, Axitinib were chosen for the TKI. The Pembrolizumab was used for immunotherapy. The stereotactic body radiation therapy and surgical excision were considered as the local therapy. The study aims to compare the age, gender, IMDC score, pathology, nbephrectomy, adverse events, progression-free survival and overall survival (OS). Results: Of all patients, the median follow-up duration was 23 months (ranging 6-117 cmonths). The PFS was 18.3 months and median OS was 33.5 months. The 2 years and 5 years survival rate was 66% and 35%, respectively. The median OS of Group A, B and C were 29.8 months, 44.6 months and not reached. 2y-OS was 58%, 67% and 89%, while 5y-OS 12%, 46% and 57%.There was no difference in age, gender, IMDC score, pathology, synchronous metastases or nephterectomy between the three groups. The prognostic result in TKI based combination therapy was superior to TKI therapy alone, which the 5y-OS was 51% and 11%, respectively. The prognostic result in group C's moderate-high risk mRCC patients was superior to group A and B. The median OS in TKI+ DC and CIK+ Pembrolizumab was 49.1 months and 53.1 months. On univariate analyses, IMDC score, nephrectomy and treatment group was associated with OS (P<0.05). On multivariate analyses, treatment group, nephrectomy was associated with OS (P<0.05). The risk of death of Group C decreased about 60% [HR 0.39 (0.17, 0.89), P=0.026]. 78 (46.4%) patients on TKI alone and 16 (61.5%) patients treated with TKI plus immunotherapy had Grade 3 or 4 adverse events. 16 (20.3%) patients had Clavien Ⅲ-Ⅳ toxicity after surgical procedures. 6 (5.7%) patients had Grade 3 toxiciy after SBRT. Conclusions Patients treated with combined therapy had better survival than those treated with anti-angiogenic agents alone. MDT approach could bring survival benefit to mRCC patients.

Objective:To investigate and compare the value of cross-sectional area measurement and width measurement by high frequency ultrasound in the diagnosis of congenital adrenal hyperplasia (CAH) in infants.Methods:The abdominal ultrasound images of 20 infants who were diagnosed as CAH in Tianjin Children′s Hospital and clinical diagnosised from November 2013 to August 2018 were analyzed retrospectively. The maximum cross-sectional area of adrenal gland and the maximum width of single limb were measured respectively to assess the size of adrenal gland. Fifty normal full-term infants were selected as control group at the same period. The differences of maximum cross-sectional area of adrenal gland, the maximum width of single limb between CAH group and control group were compared. ROC curve was plotted to compare the diagnostic values of cross-sectional area measurement and width measurement.Results:①There was significant difference in maximum cross-sectional area of adrenal gland between infants with CAH and normal infants[(129.47±37.39)mm 2 vs (54.42±20.85)mm 2; t=10.004, P<0.001]. There was significant difference in maximum width of adrenal gland between infants with CAH and normal infants [(4.56±1.20)mm vs (3.25±0.66)mm; t=5.445, P<0.001]. ②The area under ROC curve(AUC) of cross-sectional area measurement was 0.966, the best cutoff value was 87.5 mm 2, the sensitivity was 95.0%, and the specificity was 92.5%. AUC of width measurement was 0.817, the best cutoff value was 5.25 mm, the sensitivity was 90.0%, and the specificity was 62.5%. The difference of AUC between cross-sectional area measurement and width measurement was 0.149, which was statistically significant ( Z=2.309, P=0.021). Conclusions:Both cross-sectional area measurement and width measurement by high frequency ultrasound have diagnostic values for CAH in infants, with the former more valuable than the latter.
