BACKGROUND/AIMS: Pyogenic liver abscess (PLA) is a serious, life threatening condition with a high mortality rate that represents a diagnostic and therapeutic challenge. The aim of this study was to collect demographic data and clinical, laboratory and microbiological characteristics of PLA patients treated between 2000 and 2010. We also aimed to collect information regarding our management experience of these cases. METHODS: As a retrospective review, 47 patients with PLA in a tertiary referral center were examined to determine their demographic characteristics, clinical features, and laboratory, imaging, and microbiologic findings as well as the treatment outcome. RESULTS: Cryptogenic PLA was the most frequently identified type of PLA, while benign biliary tract disease was the most frequently identifiable cause of PLA (18/47 patients; 38.3%). Leukocytosis and elevated alanine transaminase were common laboratory findings and were observed in 35 (74.5%) and 22 (46.8%) patients, respectively. Increased fibrinogen was also detected in 11 of 15 investigated cases (73.3%). Notably, infection-induced thrombocytopenia occurred in 8 patients (17%). Diabetes mellitus was associated with the occurrence of infection induced shock when compared to the non-diabetic group (p<0.05). Patients with two or more comorbid diseases had longer hospitalizations when compared to patients with one comorbid disease or those without comorbidities (p<0.001). The number of days needed to establish diagnosis was correlated with the length of hospitalization (p<0.001). The overall hospital mortality rate was 2.1% (1/47). CONCLUSIONS: Characteristics of PLA patients from the past 10 years are presented. The number of days needed to establish a PLA diagnosis was correlated with the length of the hospital stay. The hospital stay of PLA patients can be further improved by early diagnosis and effective treatments during the early stages of PLA progression.

Objective To explore the relationship between accessory renal artery(ARA)and essential hypertension,and the possible mechanism using CT angiography(CTA).Methods The patients who underwent CTA examination on renal artery were reviewed retrospectively in our hospital.A variety of CTA reconstruction techniques were used to observe the type and number of ARA,as well as the diameter of ARA and the main renal artery.Results A total of 126 ARA(66 left ARA and 60 right ARA)were found in 253 patients. 10% of the patients had more than two ARAs.In 164 patients with essential hypertension,ARA detection rate was 40.2%(66/164).In the non-hypertension patients,the proportion of ARA was 31.5%(28/89).There was higher proportion of young(P=0.002)and male (P=0.022)patients in ARA hypertension group compared with ARA non-hypertension group.There were no significant differences on the prevalence of type(P=0.826)and number of ARA(P=0.501)between these two groups.In all of the patients with single ARA,no significant differences were detected on the ratios of diameter of ARA and main renal artery between the two groups(P=0.32). However,in ARA hypertension group,the diameter of main renal artery on the ARA side was significantly smaller than that on the opposite side(P=0.01).In non-hypertension ARA group,no statistical difference was found between the diameter of bilateral main renal arteries(P=0.06).Conclusion ARA is more prevalent in essential hypertensive patients,especially in young male.The decrease of the diameter of main renal artery in the ARA side may be a possible mechanism for essential hypertension.

Objective:To analyze the prognostic factors of primary and metastatic tumor resection for metastatic renal carcinoma.Methods:Clinical data of 12 cases of renal carcinoma with distant metastasis admitted to the Peking University Third Hospital from June 2011 to December 2019 were analyzed retrospectively, including 10 males and 2 females. Age was from 36 to 67 years old, with average of 53.7 years old. BMI was 20.9-30.8 kg/m 2, with average of 25.8 kg/m 2.There were 6 cases of right kidney tumor and 6 cases of left kidney tumor. The diameter of the primary tumor was 2.7-16.0 cm, with an average of 7.1 cm. There were 2 cases of lung metastasis, 1 case of liver metastasis and 9 cases of bone metastasis. All the 12 patients underwent primary and metastatic tumorectomy. Postoperative pathological results showed 10 cases of clear cell carcinoma, 1 case of papillary type 2 tumor and 1 case of collecting duct carcinoma. The pathological results of the metastases were the same as those of the original lesions. Results:All the 12 patients underwent primary and metastatic renal carcinoma resection, among which 3 received postoperative chemotherapy and 6 received radiotherapy .Two patients were treated with targeted drugs. The interval between primary resection and metastatic resection was 1-84 months, and the median time was 2.5 months. In this study, 12 patients were followed up for 2-96 months, with the median survival time of 34 months, and mortality rate of 25%.There was no significant correlation between age( P=0.265), gender( P=0.183), BMI( P=0.152), primary tumor size ( P=0.082), radiotherapy, chemotherapy or targeted therapy ( P=0.915) and overall survival, and the interval between primary resection and metastatic resection ( P=0.046) was significantly correlated with overall survival. Conclusion:The interval between primary and metastatic tumor resection was a risk factor for the prognosis of patients.

Objective:To investigate the clinicopathological characteristics and prognosis of pT 3a stage non-clear cell renal cell carcinoma (nccRCC). Methods:The clinical data of 438 patients with pT 3a stage renal cell carcinoma treated by surgery at Peking University Third Hospital from March 2013 to March 2023 were retrospectively analyzed. Among them, there were 58 cases in the nccRCC group and 380 cases in the clear cell RCC (ccRCC) group. There were statistically significant differences in age, American Society of Anesthesiologists (ASA) classification, and comorbidities between the two groups (all P<0.05). Therefore, propensity score matching was used to adjust the baseline data of the two groups. After matching, there were 58 cases in the nccRCC group and 232 cases in the ccRCC group. There were no statistically significant differences in gender (male/female: 34/24 cases and 165/67 cases), age (53.3±16.8 years and 56.6±11.6 years), ASA classification (1/2/3/4: 19/34/5/0 cases and 60/163/8/1 cases), comorbidities (present/absent: 16/42 cases and 76/156 cases), tumor maximum diameter [6.7 (5.3, 8.4) cm and 5.8 (4.6, 7.8) cm], and nephron sparing surgery(yes/no: 4/54 cases and 15/217 cases) (all P > 0.05). The overall survival (OS) and progression-free survival (PFS) of two groups were compared, the Kaplan-Meier method was employed to plot survival curves. Cox proportional hazards regression model was used to analyze the relationship between different pT 3a characteristics in the nccRCC group and progression-free survival. Results:In the matched cohort, the median follow-up time for the nccRCC group and ccRCC group were 28.0 (16.3, 45.3) months and 31.0 (18.0, 57.0) months, respectively. The pathological types in the nccRCC group included chromophobe renal cell carcinoma (20 cases, 34.5%), papillary renal cell carcinoma (20 cases, 34.5%), Xp11.2 translocation renal cell carcinoma (8 cases, 13.8%), mucinous tubular and spindle cell carcinoma (3 cases, 5.2%), and other or unclassified renal cell carcinoma (7 cases, 12.1%). There was no statistical significance between the nccRCC and ccRCC groups in terms of invasion of the renal vein without involvement of the vein wall (yes/no: 5/53 cases and 41/191 cases), vascular invasion (yes/no: 18/40 cases and 52/180 cases), invasion of the perirenal fat (yes/no: 15/43 cases and 39/193 cases), invasion of the renal pelvis and sinus (yes/no: 51/7 cases and 200/32 cases), or sarcomatoid differentiation (yes/no: 2/56 cases and 4/228 cases)(all P > 0.05). However, there was a statistically significant difference in lymph node involvement (yes/no: 3/229 cases and 9/49 cases, P < 0.01). The 5-year PFS and OS of nccRCC group were 67% (95% CI 52%-86%) and 70% (95% CI 55%-89%) respectively. While the 5-year PFS and OS of ccRCC group were 78% (95% CI 70%-86%) and 87% (95% CI 81%-93%) respectively. There was no statistically significant difference in PFS between the two groups ( P>0.05), but there was a statistically significant difference in OS ( P<0.01). Furthermore, within specific pathological types, the 5-year PFS and OS rates of chromophobe renal cell carcinoma were 88% (95% CI 67%-100%) and 86% (95% CI 63%-100%) respectively, followed by papillary renal cell carcinoma with 5-year PFS of 55% (95% CI 33%-91%) and 5-year OS of 65% (95% CI 44%-97%), and Xp11.2 translocation renal cell carcinoma with 5-year PFS of 38% (95% CI 9%-100%) and 5-year OS of 43% (95% CI 10%-100%). The difference in PFS and OS between ccRCC, chromophobe renal cell carcinoma, papillary renal cell carcinoma, and Xp11.2 translocation renal cell carcinoma was statistically significant ( P<0.01). In addition, the multivariate Cox regression analysis revealed that the independent risk factor for PFS in nccRCC patients is the invasion of the renal vein without venous wall involvement ( HR = 8.0, 95% CI 1.8-36.2, P<0.01). Conculsions:Compared to ccRCC, pT 3a nccRCC is more prone to lymph node metastasis. Among them, papillary renal cell carcinoma and Xp11.2 translocation renal cell carcinoma have a poorer prognosis, resulting in an overall lower survival period for pT 3a nccRCC patients. Among different pT 3a characteristics, invasion of the renal vein without invading the vein wall is an independent risk factor for PFS in nccRCC patients.

High mobility group protein B1 (HMGB1), a highly conversed non-histone nucleoproteins with strong pro-inflammatory property, is one of the inflammatory mediator of the acute respiratory distress syndrome (ARDS). Numerous studies have confirmed that HMGB1 regulates ARDS by binding to receptor for advanced glycation end product (RAGE), Toll-like receptor (TLR) and etc. And it can significantly increase the mortality of ARDS. But the mechanism of HMGB1 release is still unclear. This study focuses on the HMGB1 release progress, which connected with Janus kinases/signal transducer and activator of transcription (JAK/STAT), nuclear factor-κB (NF-κB), Notch, inflammasome, tumor necrosis factor (TNF), mitogen-activated protein kinase (MAPK), reactive oxygen species (ROS), peroxisome proliferator-activated receptor (PPAR) and other signaling or dependent pathways in ARDS.

Objective:To investigate the relationship between advanced glycation end products (AGEs) in the lens and type 2 diabetes mellitus.Methods:226 subjects were recruited between August 14 to September 14, 2018 from the Endocrinology Department of Central South University Xiangya Hospital, the Third Hospital of Changsha City, and the Fourth Hospital of Changsha City. The OGTT test, combined with clinical indicators, were used as the gold standard. Subjects were screened for type 2 diabetes using both the lens AGE fluorescence assay and the gold standard. Drawing the receiver operating characteristic (ROC) curve, we calculated the area under the curve (AUC) and its 95% CI and calculated the AGE for the diagnosis of type 2 diabetes. Sensitivity, specificity, Youden index, Kappa value, and its 95% CI, and the optimal cut-off value were determined according to the Youden index. Taking diabetes as the outcome indicator and AGE as the binary indicator, three logistic regression models were constructed. Stratified by age and sub-center, the differences between fasting blood glucose and 2 h postprandial blood glucose were compared between the AGE-negative and AGE-positive groups to determine the relationship between AGE and diabetes. Results:The area under the ROC curve was 0.86(95% CI: 0.81-0.91). According to the Youden index, the optimal cut-off point for AGE was 0.24. At this time, the sensitivity was 82.86(95% CI: 77.81-87.91), the specificity was 77.06(95% CI: 71.43-82.7), the Youden index was 59.92(95% CI: 53.36-66.49), the Kappa value was 79.62(95% CI: 74.22-85.02). Except for the 20-39-year-old group, the fasting blood glucose and 2 h postprandial blood glucose of the AGE-positive group in different age groups, different sub-centers, and the general population were higher than those of the AGE-negative group (all P<0.05). After adjusting for the confounding effects of age, gender, and sub-center (model 3), the relative risk of diabetes in the AGE-positive group was 11.75 times higher than the AGE-negative group (95% CI: 5.61-24.60), all with P<0.001. Conclusion:There was a high correlation between AGE in the lens and the risk of type 2 diabetes. When the cut-off point of AGE is 0.24, it had high sensitivity and specificity and could be used as a practical tool for early screening of type 2 diabetes.
