Objective: To investigate the application value of computed tomography (CT) examination of lymph node short diameter in evaluating cardia-left gastric lymph node metastasis in thoracic esophageal squamous cell carcinoma (ESCC). Methods: A total of 477 patients with primary thoracic ESCC who underwent surgical treatment in the Affiliated Cancer Hospital of Zhengzhou University from January 2013 to December 2017 were collected. All of them underwent McKeown esophagectomy plus complete two-field or three-field lymph node dissection. Picture archiving and communication system were used to measure the largest cardia-left gastric lymph node short diameter in preoperative CT images. The postoperative pathological diagnosis results of cardia-left gastric lymph node were used as the gold standard. Receiver operating characteristic (ROC) curve was used to evaluate the efficacy of CT lymph node short diameter in detecting the metastasis of cardia-left gastric lymph node in thoracic ESCC, and determine the optimal cut-off value. Results: The median short diameter of the largest cardia-left gastric lymph node was 4.1 mm in 477 patients, and the largest cardia-left gastric lymph node short diameter was less than 3 mm in 155 cases (32.5%). Sixty-eight patients had cardia-left gastric lymph node metastases, of which 38 had paracardial node metastases and 41 had left gastric node metastases. The lymph node ratios of paracardial node and left gastric node were 4.0% (60/1 511) and 3.3% (62/1 887), respectively. ROC curve analysis showed that the area under the curve of CT lymph node short diameter for evaluating cardia-left gastric lymph node metastasis was 0.941 (95% CI: 0.904-0.977; P<0.05). The optimal cut-off value of CT examination of the cardia-left gastric lymph node short diameter was 6 mm, and the corresponding sensitivity, specificity and accuracy were 85.3%, 91.7%, and 90.8%, respectively. Conclusion: CT examination of lymph node short diameter can be a good evaluation of cardia-left gastric lymph node metastasis in thoracic ESCC, and the optimal cut-off value is 6 mm.

OBJECTIVE: To construct a preoperative evaluation system for partial nephrectomy using CT three-dimensional visualization technology and to explore its practical value. METHODS: The clinical data of the patients who underwent partial nephrectomy for renal tumors in Department of Urology, Peking University First Hospital were collected retrospectively. At the same time, the homogenized standard data of patients who underwent partial nephrectomy for renal tumors were collected in 16 clinical centers in China. The CT three-dimensional visualization system was applied (IPS system, Yorktal) to evaluate tumor anatomy, blood supply, perirenal fat and other information. The parameters were summarized to build a three-dimensional nephrometry system, on the basis of which virtual surgery design and intraoperative navigation were completed. RESULTS: A three-dimensional visualization image was established based on the enhanced CT urography. The nephrometry system included the longest diameter and volume of the tumor, proportion volume of tumor invading the parenchyma, maximum depth of the tumor invading the parenchyma, contact surface area, flatness of the tumor surface, renal segment where the tumor was located, vascular variation, and perirenal fat. The average two-dimensional diameter of the tumor was (2.78±1.43) cm, the average three-dimensional maximum diameter was (3.09±1.35) cm, and the average postoperative pathological size was (3.01±1.38) cm. The maximum tumor diameter in the three-dimensional image was significantly related to the prolonged renal artery clamping time and intra-operative blood loss (r=0.502, P=0.020; r=0.403, P=0.046). The three-dimensional and pathological tumor volume were (25.7±48.4) cm³ and (33.0±36.4) cm³, respectively (P=0.229). The tumor volume was significantly related to the intraoperative blood loss (r=0.660, P < 0.001). The proportion volume of the tumor invading into renal parenchyma was significantly related to the prolongation of renal artery clamping and the occurrence of postoperative complications (r=0.410, P=0.041; r=0.587, P=0.005). The tumor contact surface area and the presence of vascular variation did not show correlation with the perioperative data and postoperative complications. While the preoperative evaluation was completed, the reconstructed three-dimensional image could be zoomed, rotated, combined display, color adjustment, transparency, and simulated cutting on the Touch Viewer system. The process generally consisted of showing or hiding the tissue, adjusting the transparency of the interested area, rotating and zooming the image to match the position of the surgical patient. Together, these functions met the requirements of preoperative virtual surgery plan and intraoperative auxiliary navigation. CONCLUSION Three-dimensional images can provide a more intuitive anatomical structure. The CT three-dimensional visua-lization system clearly displays tumor anatomical parameters, blood supply and perirenal fat. The three-dimensional nephrometry system for renal tumors can help predict the difficulty of partial nephrectomy and perioperative complications. Importing the reconstructed three-dimensional visualization image into the specified program or robot operating system can complete virtual surgery and intraoperative navigation, helping the surgeon to better grasp the surgical process. The indexes included in the nephrometry system and the score weights of each index need to be confirmed and perfected by multi-center study with large samples.

OBJECTIVE: To evaluate the incidence and clinical characteristics of metabolic syndrome (MS) within one year after hematopoietic stem cell transplantation (HSCT) in order to screen the risk factors for HSCT-MS, provide early intervention and improve the long-term quality of survival of patients. METHODS: The clinical follow-up data of 64 HSCT patients (survival time > 1 year) who received HSCT in our center from January 2007 to August 2018 were collected. Among them, 50 cases were allogeneic hematopoietic stem cell transplantation (allo-HSCT) and 14 cases were autologous hematopoietic stem cell transplantation (auto-HSCT). The changes of MS-related indexes and clinical characteristics before and 1, 3, 6 and 12 months after HSCT were analyzed retrospectively. RESULTS: In allo-HSCT group, 14 cases were diagnosed as MS before operation, including high-density lipoprotein cholesterol (hypo-HDL-C)> hyper triglycerides（hyper-TG）> hyper fasting glucose（hyper-FBG）> abdominal obesity (AO) > hypertension. The preoperative diagnosis of MS in the auto-HSCT group was 5 cases, in the order of hyper-FBG> hyper-TG> AO> hypo-HDL-C> hypertension. Incidence of MS at 1, 3, 6 and 12 months after transplantation: 19, 26, 24 and 20 cases in the allo-HSCT group, respectively; auto-HSCT group were 7, 7, 6 and 6 cases, respectively. Hyper-TG and hypo-HDL-C were prominent in both groups. CONCLUSION The incidence of HSCT-MS is significantly higher within 1 year after HSCT. Regardless of allo-HSCT and auto-HSCT, the prevention and control of HSCT-MS is emphasized as an important guarantee to improve the long-term survival quality of HSCT patients.

BACKGROUND: Shenyankangfu Tablet (SYKFT) is a Chinese patent medicine that has been used widely to decrease proteinuria and the progression of chronic kidney disease. OBJECTIVE: This trial compared the efficacy and safety of SYKFT, for the control of proteinuria in primary glomerulonephritis patients, against the standard drug, losartan potassium. DESIGN, SETTING, PARTICIPANTS AND INTERVENTION: This was a multicenter, double-blind, randomized, controlled clinical trial. Primary glomerulonephritis patients, aged 18-70 years, with blood pressure ≤ 140/90 mmHg, estimated glomerular filtration rate (eGFR) ≥ 45 mL/min per 1.73 m MAIN OUTCOME MEASURES: The primary outcome was change in the 24-hour proteinuria level, after 48 weeks of treatment. RESULTS: A total of 735 participants were enrolled. The percent decline of urine protein quantification in the SYKFT group after 48 weeks was 8.78% ± 2.56% (P = 0.006) more than that in the losartan 50 mg group, which was 0.51% ± 2.54% (P = 1.000) less than that in the losartan 100 mg group. Compared with the losartan potassium 50 mg group, the SYKFT plus losartan potassium 50 mg group had a 13.39% ± 2.49% (P < 0.001) greater reduction in urine protein level. Compared with the losartan potassium 100 mg group, the SYKFT plus losartan potassium 100 mg group had a 9.77% ± 2.52% (P = 0.001) greater reduction in urine protein. With a superiority threshold of 15%, neither was statistically significant. eGFR, serum creatinine and serum albumin from the baseline did not change statistically significant. The average change in TCM syndrome score between the patients who took SYKFT (-3.00 [-6.00, -2.00]) and who did not take SYKFT (-2.00 [-5.00, 0]) was statistically significant (P = 0.003). No obvious adverse reactions were observed in any group. CONCLUSION: SYKFT decreased the proteinuria and improved the TCM syndrome scores of primary glomerulonephritis patients, with no change in the rate of decrease in the eGFR. SYKFT plus losartan potassium therapy decreased proteinuria more than losartan potassium therapy alone. TRIAL REGISTRATION NUMBER NCT02063100 on ClinicalTrials.gov.

OBJECTIVE: To investigate the value of preoperative three-dimensional image reconstruction in the treatment of ureteropelvic junction obstruction (UPJO). METHODS: We reviewed data on 40 patients (22 male cases, and 18 female cases) diagnosed with UPJO in Peking University First Hospital from May 2017 to April 2019. The median age was 26.5 years (IQR 23.25-38.75) years. There were 11 patients complicated with ectopic vessels, 14 patients with kidney stones, 3 patients with horseshoe kidney, and 6 patients with obstruction after pyeloplasty. All the patients underwent preoperative enhanced CT scan, and the CT data were reconstructed into three-dimensional image models. The obstruction position of ureteropelvic junction and the relationship between ureteropelvic junction and blood vessels and organs were observed by three-dimensional models to assist planning surgery. Thirty-seven patients underwent laparoscopic pyeloplasty (including 3 cases combined with pyelolithotomy with flexible cystoscope, 1 case combined with pyelolithotomy by sun-style cystoscope, 1 case with laparoscopic ureter resection and anastomosis, 3 cases of laparoscopic pyeloplasty of horseshoe kidney), 2 patients underwent laparoscopic ventral onlay lingual mucosal graft ureteroplasty, and 1 patient underwent robot-assisted laparoscopic pyeloplasty. RESULTS: Three-dimensional CT image clearly showed the relationship between the obstruction of ureteropelvic junction and blood vessels and organs after three-dimensional reconstruction. The type, diameter, position and direction of the ectopic vessels could be observed clearly before operation according to the three-dimensional reconstruction model, and the number, size, location and shape of renal calculi or other masses, the number of involved renal calyces and the anatomical distribution in the renal pelvis and calyces could be also evaluated preoperatively. After comprehensive analysis of the above information, individualized operation plans were performed on the patients, all the 40 cases were successfully completed with the surgery without any transfer to open surgery. The average operative time was (129.91±37.90) min (range: 75 to 273), the average blood loss was (48.1±78.0) mL (range: 10 to 400), the average hospitality was (5.04±1.99) d (range: 2 to 10), and the average postoperative drainage time was (3.8±1.4) d (range: 2 to 8). CONCLUSION The preoperative three-dimensional image reconstruction has a high clinical value in the treatment of ureteropelvic junction obstruction, and it is of great help to assist surgery planning and is worthy of further clinical promotion and application.

Objectives: To explore the relationship between body fat indexes and hypertension levels by quantitative CT (QCT) study. Methods: A total of 1488 participants from "prospective urban-rural epidemiology (PURE) study" were enrolled. The participants' age were from 42 to 82 years; based on blood pressure (BP) they were divided into 2 groups: Non-hypertension group, n=783 and Hypertension group, n=705. QCT fat measurement software was used to examine L2 level abdominal visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT); body mass index (BMI), waist circumferences (WC), hip circumferences (HC) and waist-to-height ratio (WHtR) were measured and calculated; liner Logistic regression analysis and 2-classified Logistic analysis were conducted to study the relationships between hypertension and anthropometric indices, abdominal VAT, SAT respectively. Results: Compared with Non-hypertension group, Hypertension group had increased BMI, WC, HC, WHtR, abdominal VAT and SAT, P<0.05. BMI, WC, HC, WHtR, abdominal VAT and SAT were related to both systolic BP (SBP) and diastolic BP (DBP), P<0.05. Multivariable Logistic regression analysis indicated that WHtR, abdominal VAT, SAT were the independent impact factors of SBP and WC, abdominal VAT were the independent impact factors of DBP; further investigation showed that abdominal VAT and WC were the independent impact factors of hypertension. Conclusions: Abdominal VAT was robustly related to hypertension in Chinese population, it might be helpful for risk stratification in hypertension patients.

Aim To explore the correlation between elevated plus maze (EPM) and elevated zero maze (EZM),as two type animal models of state anxiety in Kunming mice. Methods The behavior of adult,♂/♀,Kunming mice in EPM and EZM was recorded by sequence,for 5 min,with a one-week inter-trial interval. The following parameters were evaluated:percentage of time in open arms (Otime%) and total entries into open and closed arms(Entries). Subsequently,descriptive analysis,fac-tor analysis,cluster analysis,correlation analysis and consisten-cy test were calculated for these parameters. Results T test showed that, compared with EPM, Otime% of EZM (male/fe-male/both sex) decreased, while Entries (male/both sex) in-creased significantly;Fiedman test showed that Otime% (male/female/both sex) and Entries(female/both sex) of both EPM and EZM had great difference between the 5 repeated fragments;Wilcoxon test showed that, compared with EPM, Otime% of EZM in 1st min (male/female/both sex), 2nd min (male/fe-male/both sex),3rd min (female/both sex) decreased, while the Entries in 1st min (male/both sex), 4th min (male/fe-male/both sex),5th min(both sex) increased markedly. Clus-ter analysis showed that EPM and EZM parameters could be clustered into two groups:EPM group and EZM group(male/fe-male/both sex). Factor analysis indicated that the EPM and EZM parameters could be extracted as two factors: EPM factor and EZM factor (male/female/both sex). Correlation analysis displayed either general(in Otime%) or poor(in Entries) cor-relation(male/female/both sex) between EPM and EZM param-eters. Consistency test displayed general consistency (male/fe-male/both sex) in Otime% between EPM and EZM. Conclu-sions Despite of the similar internal principles to induce state anxiety,the different external environment(structure) results in different behavioral patterns,different structure dimensions,fair correlation and concordance between EPM and EZM, and the stable index of EPM and EZM might be preferred to Otime%.

Objective:To investigate the mechanism of chronic bronchitis with recurrent long duration infections in the production of MPO anti-neutrophil cytoplasmic antibodies(ANCA). Methods:Rats were gave intratracheal injection of LPS and smoked to established chronic bronchitis ( CB ) model. Rat neutrophils were incubated with phorbol-12-myristate-13-acetate ( PMA ) to induce Neutrophil extracellular traps(NETs). NETs were then used to immune chronic bronchitis rats. Serum concentrations of myeloperoxidase anti-neutrophil cytoplasmic antibodies(MPO-ANCA),Citrullinated Histone H3(CitH3),Interferon-α(IFN-α)were evaluated. Results:(1)The serum levels of MPO-ANCA in chronic bronchitis rats immuned with NETs(CB/NETs)were significantly higher than those in chronic bronchitis rats(CB)and healthy control rats,(62. 4975±19. 63764)ng/ml vs (17. 3806±4. 88649)ng/ml,(20. 8884± 4. 39607)ng/ml(both P<0. 01). (2)The serum levels of CitH3 in CB/NETs rat were significantly higher than those in CB rat and healthy control rats,(32. 5974±20. 2915)ng/ml vs (8. 8568±2. 36692)ng/ml,(5. 6225±0. 83738)ng/ml(P<0. 05,P<0. 01). (3)The serum levels of IFN-α were found increased sharply in two CB/NETs rats(3735.7,3428.4 pg/ml). (4)Renal function among three groups showed no significant difference yet. ( 5 ) Serum CitH3 level showed a positive correlation with serum MPO-ANCA level(r=0. 61,P<0. 05). Conclusion:Chronic bronchitis with recurrent infections could induce the production of ANCA probably by the stimulation of NETs,but whether it might develop to AAV remains need a duration.
