Objective:To summarize the clinical characteristics of patients with renal angiomyolipoma(RAML)combined with inferior vena cava(IVC)tumor thrombus,and to explore the feasibility of par-tial nephrectomy and thrombectomy in this series of patients.Methods:The clinical data of patients diagnosed with RAML combined with IVC tumor thrombus in the Department of Urology of the Peking University Third Hospital from April 2014 to March 2023 were retrospectively analyzed,and demographic and perioperative data of RAML patients with IVC tumor thrombus were recorded and collected from Elec-tronic Medical Record System,including age,gender,surgical methods,and follow-up time,etc.The clinical characteristics between classic angiomyolipoma(CAML)patients with IVC tumor thrombus and epithelioid angiomyolipoma(EAML)patients with IVC tumor thrombus were compared to determine the clinical characteristics of these patients.Results:A total of 11 patients were included in this study,in-cluding 7 patients with CAML with IVC tumor thrombus and 4 patients with EAML with IVC tumor thrombus.There were 9 females(9/11,81.8％)and 2 males(2/11,18.2％),with an average age of(44.0±17.1)years.9 patients(9/11,81.8％)experienced clinical symptoms,including local symp-toms including abdominal pain,hematuria,abdominal masses,and systemic symptoms including weight loss and fever;2 patients(2/11,18.2％)with RAML and IVC tumor thrombus did not show clinical symptoms,which were discovered by physical examination.Among the 11 patients,10 underwent radical nephrectomy with thrombectomy,of whom,3 underwent open surgery(3/10,30.0％),2 underwent laparoscopic surgery(2/10,20.0％),and 5 underwent robot-assisted laparoscopic surgery(5/10,50.0％).In addition,1 patient underwent open partial nephrectomy and thrombectomy.The patients with EAML combined with I VC tumor thrombus had a higher proportion of systemic clinical symptoms(100％vs.0％,P=0.003),more intraoperative bleeding[400(240,3 050)mL vs.50(50,300)mL,P=0.036],and a higher proportion of tumor necrosis(75％vs.0％,P=0.024)compared to the patients with CAML combined with I VC tumor thrombus.However,there was no statistically significant difference in operation time[(415.8±201.2)min vs.(226.0±87.3)min,P=0.053]between the two groups.Conclusion:Compared with the patients with CAML and IVC tumor thrombus,the patients with EAML and IVC tumor thrombus had a higher rate of systemic symptoms and tumor necrosis.In addi-tion,in the selected patients with CAML with IVC tumor thrombus,partial nephrectomy and tumor thrombectomy could be performed to better preserve renal function.

Objective:To analyze the clinicopathological characteristics and prognosis of patients with multilocular cystic renal neoplasm of low malignant potential and compare the clinicopathological charac-teristics of patients with multilocular cystic renal neoplasm of low malignant potential who underwent different surgical methods.Methods:Clinicopathological data and prognosis of patients admitted to Peking University Third Hospital from January 2010 to September 2023 were collected.Patients who underwent radical nephrectomy or nephron-sparing surgery and were pathologically diagnosed with multilocular cystic renal neoplasm of low malignant potential were identified.Based on the surgical methods,the patients were divided into radical nephrectomy group and nephron-sparing surgery group.The clinicopathological characteristics of the two groups were compared.Results:A total of 35 patients were enrolled in this study.The median age at diagnosis was 53.0(39.0-62.0)years.Among the 35 patients,23 were males(65.7％)and 12 were females(34.3％).Nine patients underwent radical nephrectomy(25.7％),while 26 patients underwent nephron-sparing surgery(74.3％).The clinical T-stage of 35 patients did not exceed T2a stage.The median operation time was 145.0 min,and the median estimated intraoperative blood loss was 20.0 mL.The median postoperative hospitalization days was 6.0 d.The postoperative pathological results did not indicate renal sinus invasion,sarcomatous change,adrenal invasion or lymph node invasion.Based on the surgical methods,the patients were divided into a radical nephrectomy group and a nephron-sparing surgery group.There was no significant difference in clinicopathological charac-teristics between the two groups.Except for one patient who was lost to the follow-up,all the other patients were followed up for 8-111 months,with a median follow-up time of 70.5 months.Only one patient died from non-cancer-specific reasons,other patients had no tumor metastasis or recurrence.Conclusion:Patients with multilocular cystic renal neoplasm of low malignant potential have a good prog-nosis.There is no significant difference in clinicopathological characteristics of patients between nephron-sparing surgery group and radical nephrectomy group for multilocular cystic renal neoplasm of low malig-nant potential.

Objective:To investigate the postoperative renal function and oncologic outcomes of cystic renal cell carcinoma with partial nephrectomy,and to compared the single-center data on surgical out-comes with the Surveillance,Epidemiology,and End Results(SEER)database.Methods:This was a retrospective study that included the patients with cystic renal cell carcinoma who underwent partial ne-phrectomy in the Department of Urology,Peking University Third Hospital(PUTH)from 2010 to 2023.The clinical data and depicting baseline characteristics were collected.Renal dynamic imaging and the Chinese Coefficients for Chronic Kidney Disease Epidemiology Collaboration(C-CKD-EPI)formulae were used to calculate the estimated glomerular filtration rate(eGFR).The renal function curves over time were then plotted,and the patients were followed-up to record their survival status.Cases of cystic renal cell carcinoma in the SEER database between 2000 and 2020 were included,propensity score matching(PSM)was performed to balance the differences between SEER cohort and PUTH cohort,and the cancer-specific survival(CSS)curves for both groups were plotted and statistical differences were calcu-lated by the Kaplan-Meier method.Results:A total of 38 and 385 patients were included in the PUTH cohort and SEER cohort,respectively,and 31 and 72 patients were screened in each cohort after PSM.Of the baseline characteristics,only tumor size(P=0.042)was found to differ statistically between the two groups.There was no statistically significant difference between the two cohorts in terms of CSS after PSM(P=0.556).The median follow-up time in the SEER cohort was 112.5(65,152)months and a 10-year survival rate of 97.2％,while the PUTH cohort had a median follow-up of 57.0(20,1 172)months and a 10-year survival rate of 100.0％.There was no statistically significant difference between eGFR determined by preoperative renal dynamic imaging and the results of the C-CKD-EPI formulae based on creatinine estimation(P=0.073).There was a statistically significant difference in eGFR among the preoperative,short-term postoperative,and long-term postoperative(P＜0.001),which was characterized by the presence of a decline in renal function in the short-term postoperative period and the recovery of renal function in the long-term period.Conclusion:Partial nephrectomy for cystic renal cell carcinoma is safe and feasible with favorable renal function and oncologic outcomes.

Objective:To predict the 3-year cancer-specific survival(CSS)of patients with non-meta-static T3a renal cell carcinoma after surgery.Methods:A total of 336 patients with pathologically con-firmed T3a N0-1M0 renal cell carcinoma(RCC)who underwent surgical treatment at the Department of Urology,Peking University Third Hospital from March 2013 to February 2021 were retrospectively collect-ed.The patients were randomly divided into a training cohort of 268 cases and an internal validation co-hort of 68 cases at an 4∶1 ratio.Using two-way Lasso regression,variables were selected to construct a nomogram for predicting the 3-year cancer-specific survival(CSS)of the patients with T3aN0-1M0 RCC.Performance assessment of the nomogram included evaluation of discrimination and calibration ability,as well as clinical utility using measures such as the concordance index(C-index),time-dependent area un-der the receiver operating characteristic curve[time-dependent area under the curve(AUC)],calibra-tion curve,and decision curve analysis(DCA).Risk stratification was determined based on the nomo-gram scores,and Kaplan-Meier survival analysis and Log-rank tests were employed to compare progres-sion-free survival(PFS)and cancer-specific survival(CSS)among the patients in the different risk groups.Results:Based on the Lasso regression screening results,the nomogram was constructed with five variables:tumor maximum diameter,histological grading,sarcomatoid differentiation,T3a feature,and lymph node metastasis.The baseline data of the training and validation sets showed no statistical differences(P＞0.05).The consistency indices of the column diagram were found to be 0.808(0.708-0.907)and 0.903(0.838-0.969)for the training and internal validation sets,respectively.The AUC values for 3-year cancer-specific survival were 0.843(0.725-0.961)and 0.923(0.844-1.002)for the two sets.Calibration curves of both sets demonstrated a high level of consistency between the actual CSS and predicted probability.The decision curve analysis(DCA)curves indicated that the column dia-gram had a favorable net benefit in clinical practice.A total of 336 patients were included in the study,with 35 cancer-specific deaths and 69 postoperative recurrences.According to the line chart,the patients were divided into low-risk group(scoring 0-117)and high-risk group(scoring 119-284).Within the low-risk group,there were 16 tumor-specific deaths out of 282 cases and 36 postoperative recurrences out of 282 cases.In the high-risk group,there were 19 tumor-specific deaths out of 54 cases and 33 post-operative recurrences out of 54 cases.There were significant differences in progression-free survival(PFS)and cancer-specific survival(CSS)between the low-risk and high-risk groups(P＜0.000 1).Conclusion:A nomogram model predicting the 3-year CSS of non-metastatic T3a renal cell carcinoma patients was successfully constructed and validated in this study.This nomogram can assist clinicians in accurately assessing the long-term prognosis of such patients.

OBJECTIVE To explore the construction of mind map by clinical pharmacists for the consultation of pulmonary nocardiosis and its application in clinical practice， and to provide reference for promoting the correct selection of nocardiosis treatment drugs in clinical practice and ensuring drug safety and efficacy. METHODS A total of 7 patients with Nocardia pulmonary infection from January 2017 to April 2022 in our hospital were collected. Based on evidence-based medicine， a consultation mind map （mainly including understanding the medical history， identifying infectious bacteria， identifying risk factors， developing treatment plans， and conducting evaluations） was constructed to address the difficulties of large differences in drug sensitivity among different strains of Nocardia and numerous adverse reactions of Compound sulfamethoxazole as a first-line drug. The treatment plan was developed for 7 patients with pulmonary nocardiosis， and whole-process pharmaceutical care was provided. RESULTS Combined with the mind map， different antibiotic combination regimens were given according to the drug sensitivity results of Nocardia， the different species of Nocardia， and the patient’s allergy history. Among them， 4 cases were treated with imipenem cilastatin， the patients receiving Compound sulfamethoxazole and linezolid for a long time were given full pharmaceutical care， and the adverse drug reactions were timely treated.CONCLUSIONS Clinical pharmacists apply the consultation mind map of pulmonary nocardiosis to the treatment of inpatients， take advantage of pharmacy， participate in clinical drug therapy， and really play a role in the clinical treatment team so as to promote rational drug use.

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.

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.

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 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.
