Primary aldosteronism(PA) is a common cause of secondary hypertension, with adrenal vein sampling(AVS)being the gold standard for etiological typing diagnosis. This retrospective study analyzed data from patients diagnosed with PA who underwent AVS or unilateral adrenalectomy at Nanjing Drum Tower Hospital′s Endocrinology Department from July 2018 to August 2021. Using multivariate logistic regression analysis, factors associated with unilateral aldosterone hypersecretion were identified. Based on these factors, a predictive model for diagnosing unilateral primary aldosteronism(UPA)was established: age <40 years, plasma aldosterone concentration(PAC)>15 ng/dL, adrenal CT indicating an unilateral typical adenoma, and spontaneous hypokalemia. This predictive model could help 14% of PA patients avoid unnecessary AVS procedures.

Objective:To investigate the application value of donor liver autologous portal venous blood rinse in orthotopic liver transplantation (OLT).Methods:The retrospective cohort study was conducted. The clinicopathological data of 35 pairs of donors and recipients who underwent OLT in the First Affiliated Hospital of University of Science and Technology of China from May 2018 to June 2019 were collected. Of the 35 donors, there were 31 males and 4 females, aged (48±9)years. Of the 35 recipients, there were 25 males and 10 females, aged (47±9)years. Of the 35 recipients, 16 recipients undergoing donor liver autologous portal venous blood rinse were allocated into the portal vein group, and 19 recipients undergoing donor liver albumin water rinse were allocated into the albumin group. Observation indicators: (1) surgical situations; (2) postoperative situations; (3) follow-up. Measurement data with normal distribution were represented as Mean± SD, and compari-son between groups was analyzed using the t test. Measurement data of skewed distribution were represented as M(range). Count data were descried as absolute numbers, and comparison between groups was analyzed using the Fisher exact probability. Results:(1) Surgical situations. The anhepatic phase time and arterial blood Ca 2+ concentration within 5 minutes after reperfusion of the recipients were (52±12)minutes and (0.99±0.10)mmol/L in the portal vein group, versus (64±12)minutes and (1.05±0.07)mmol/L in the albumin group, showing significant differences in the above indicators between the two groups ( t=2.94, 2.22, P<0.05). The mean arterial pressure, arterial blood K +concentration and arterial blood pH within 5 minutes after reperfusion of the recipients were (70±24)mmHg (1 mmHg=0.133 kPa), (4.7±1.3)mmol/L and 7.27±0.06 in the portal vein group, versus (71±28)mmHg, (4.6±1.1)mmol/L and 7.30±0.07 in the albumin group, showing no significant difference in the above indicators between the two groups ( t=0.14, 0.30, 1.22, P>0.05). (2) Post-operative situations. Cases with post-reperfusion syndrome (PRS), cases with severe PRS of cardiac arrest, cases with primary graft nonfunction of the recipients were 6, 0, 2 in the portal vein group, versus 8, 1, 1 in the albumin group, showing no significant difference in the above indicators between the two groups ( P>0.05). Total bilirubin on postoperative day 7 of the recipients was (90±52)μmol/L in the portal vein group, versus (166±112)μmol/L in the albumin group, showing a significant difference between the two groups ( t=2.66, P<0.05). International normalized ratio on postoperative day 7, the highest alanine aminotransferase and aspartate aminotransferase within 7 days after operation of the recipients were 2.1±2.0, (1 952±2 813)IU/L and (3 944±6 673)IU/L in the portal vein group, versus 1.8±0.6, (1 023±1 014) IU/L and (2 005±2 910)IU/L in the albumin group, showing no significant difference in the above indicators between the two groups ( t=0.66, 1.23, 1.08, P>0.05). Recipients with hepatic artery complication and biliary complication were 1 and 2 in the portal vein group, versus 0 and 4 in the albumin group, showing no significant difference in the above indicators between the two groups ( P>0.05). There were 3 cases and 2 cases died during the perioperative period in the portal vein group and the albumin group, respectively. (3) Follow-up. Of the 35 recipients, 30 recipients were followed up for 534(range, 28?776)days after operation. During the follow-up, there were 3 patients with postoperative complications in the portal vein group including 2 cases died and 1 case recovered after sympto-matic treatment. There were 5 patients with postoperative complications in the albumin group including 1 case died and 4 cases recovered after symptomatic treatment. Up to the follow-up date, 11 patients in the portal vein group and 16 patients in the albumin group were in good condition. Conclusion:Rinse of the donor liver with autologous portal venous blood during liver transplantation can shorten the time of anhepatic phase, without increasing the occurrence of post-reperfusion syndrome, ischemia re-perfusion injury and biliary tract complications.

Objective:To investigate the safety of minimally invasive liver resection for resectable hepatocellular carcinoma (HCC) complicated with portal hypertension.Methods:The propensity score matching and retrospective cohort study was conducted. The clinicopathological data of 807 patients with resectable HCC who underwent minimally invasive liver resection in 8 medical centers, including Sir Run Run Shaw Hospital, Affiliated with the Zhejiang University School of Medicine et al, from June 2011 to November 2022 were collected. There were 670 males and 137 females, aged 58(50,66)years. Of the 807 patients, 173 cases with portal hypertension were divided into the portal hypertension group, and 634 cases without portal hypertension were divided into the non-portal hypertension group. Observation indicators: (1) propensity score matching and comparison of general data of patients between the two groups after matching; (2) intraoperative and post-operative situations; (3) subgroup analysis. Propensity score matching was done by the 1:1 nearest neighbor matching method, with the caliper setting as 0.001. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the rank sum test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Comparison of ordinal data was constructed using the non-parameter rank sun test. Results:(1) Propensity score matching and comparison of general data of patients between the two groups after matching. Of the 807 patients, 268 cases were successfully matched, including 134 cases in the portal hypertension group and 134 cases in the non-portal hypertension group. The elimination of the tumor diameter and robot-assisted surgery confounding bias ensured comparability between the two groups after propensity score matching. (2) Intraoperative and postoperative situations. The occlusion time of porta hepatis, cases with intraoperative blood transfusion, cases with postoperative complication, cases with complication >Ⅱ grade of Clavien-Dindo classification, cases of Clavien-Dindo classification as Ⅰ grade, Ⅱ grade, Ⅲ grade, Ⅳ grade, cases with liver related complication were 27.0(15.0,43.0)minutes, 33, 55, 15, 13, 29, 14, 1, 37 in the portal hypertension group, versus 35.0(22.0,60.0)minutes, 17, 25, 5, 14, 9, 4, 1, 13 in the non-portal hypertension group, showing significant differences in the above indicators between the two groups ( Z=-2.15, χ2=6.30, 16.39, 4.38, 20.72, 14.16, P<0.05). (3) Subgroup analysis. Results of subgroups analysis showed that in cases with major live resection, the operation time, volume of intraoperative blood loss, duration of postoperative hospital stay were 243.5(174.6,296.3)minutes, 200.0(150.0,600.0)mL, 7.5(6.0,13.0)days in the portal hypertension group, versus 270.0(180.0,314.5)minutes, 200.0 (75.0,450.0)mL, 7.0(5.5,10.0)days in the non-portal hypertension group, showing no significant difference in the above indicators between the two groups ( Z=-0.54, -1.73, -0.92, P>0.05). In cases with non-major live resection, the operation time, volume of intraoperative blood loss, duration of postoperative hospital stay were 170.0(120.0,227.5)minutes, 100.0(50.0,200.0)mL, 8.0(5.0,10.0)days in the portal hypertension group, versus 170.0(120.0,227.5)minutes, 100.0(50.0,200.0)mL, 7.0(5.5,9.0)days in the non-portal hypertension group, showing no significant difference in the above indicators between the two groups ( Z=-1.39, -0.10, 1.05, P>0.05). In cases with anatomical liver resection, the operation time, volume of intraoperative blood loss, duration of postoperative hospital stay were 210.0(150.0,285.0)minutes, 150.0(50.0,200.0)mL, 8.0(6.0,9.3)days in the portal hypertension group, versus 225.5(146.3,306.8)minutes, 100.0(50.0,250.0)mL, 7.0(6.0,9.0)days in the non-portal hypertension group, showing no significant difference in the above indica-tors between the two groups ( Z=-0.75, -0.26, -0.91, P>0.05). In cases with non-anatomical liver resection, the operation time, volume of intraoperative blood loss, duration of postoperative hospital stay were 173.5(120.0,231.5)minutes, 175.0(50.0,300.0)mL, 7.0(5.0,11.0)days in the portal hyper-tension group, versus 186.0(123.0,262.5)minutes, 100.0(50.0,200.0)mL, 7.0(5.0,9.5)days in the non-portal hypertension group, showing no significant difference in the above indicators between the two groups ( Z=-0.97, -1.12, -0.98, P>0.05). Conclusion:Minimally invasive liver resection or even major liver resection is safe and feasible for screened HCC patients complicated with portal hyper-tension, but attention should be paid to the prevention and treatment of postoperative complications.

Objective:To investigate the prevalences of overweight and obesity and its relationship with the risk factors of cardiovascular diseases among physical examination population in Nanjing Drum Tower Hospital.Methods:A retrospective analysis was performed on 384 061 adults aged 20 years and older. Age- and sex-standardized prevalences of overweight and obesity were calculated using Chinese census data in 2010. Multivariate logistic regression analysis was used to assess the associations of overweight and obesity with the risk factors of cardiovascular diseases.Results:The age-standardized prevalences of overweight and obesity were 42.8% and 13.2% in men and 23.9% and 6.6% in women. A gradually increasing trend was observed in the prevalences of overweight and obesity from 2008 to 2016, especially in subjects aged 20-39 years. Overweight and obesity were significantly associated with increased risks of dyslipidemia, diabetes mellitus, hypertension, and hyperuricemia. These associations were found to be the strongest among subjects aged 20-39 years, which became weaker along with the increasing of age. The OR(95% CI) of dyslipidemia, diabetes mellitus, hypertension, and hyperuricemia were 4.23(4.01-4.47), 3.70(2.97-4.60), 6.19(5.76-6.64), and 3.66(3.45-3.88) in obese men aged 20-39 years, while 5.29(4.63-6.04), 6.38(3.86-10.55), 9.36(7.86-11.13), and 6.65(5.70-7.74) in obese women aged 20-39 years, respectively. Conclusion:The increasing trend in the prevalence of overweight and obesity is a risk factor for cardiovascular diseases in Nanjing adults, especially in individuals aged 20-39 years.

Objective:To compare the effects of intravenous anesthesia between propofol and etomidate in patients undergoing laparoscopic surgery and their effects on plasma nitric oxide (NO) and endothelin-1 (ET-1).Methods:The clinical data of 80 patients with laparoscopic surgery in Guangrao People′s Hospital from March 2017 to March 2019 were retrospectively analyzed. Among them, 40 cases were given propofol intravenous anesthesia (propofol group), and 40 cases were given etomidate intravenous anesthesia (etomidate group). The anesthetic effect, plasma NO and ET-1 levels, hemodynamic indexes and adverse reactions (muscle spasm, nausea and vomiting, injection site pain, body movement and respiratory depression) were compared between the two groups.Results:The time of consciousness disappearance, tracheal intubation, eye opening, spontaneous breathing and speech response in etomidate group were significantly shorter than those in propofol group: (57.48 ± 2.63) s vs. (86.17 ± 7.41) s, (4.39 ± 2.56) min vs. (6.42 ± 2.58) min, (5.39 ± 2.56) min vs. (9.42 ± 2.58) min, (5.21 ± 1.99) min vs. (8.75 ± 2.54) min and (8.39 ± 2.56) min vs. (8.39 ± 2.56) min, and the differences were statistically significant ( P<0.05). The levels of NO and ET-1 in the etomidate group were significantly lower than those in the propofol group at 0.5, 1.0 and 1.5 h after pneumoperitoneum ( P< 0.05). The levels of systolic blood pressure, diastolic blood pressure and oxygen saturation (SpO 2) in the etomidate group were significantly higher than those in the propofol group: (78.42 ± 4.68) mmHg (1 mmHg = 0.133 kPa) vs. (74.11 ± 6.63) mmHg, (132.86 ± 8.71) mmHg vs. (111.24 ± 3.56) mmHg and 0.982 ± 0.032 vs. 0.953 ± 0.043, and the differences were statistically significant ( P<0.05). The incidence of adverse reactions in the etomidate group was significantly lower than that in the propofol group: 17.5% (7/40) vs. 47.5% (19/40), P<0.05. Conclusions:Compared with propofol intravenous anesthesia, etomidate intravenous anesthesia in laparoscopic surgery patients has more stable hemodynamics and better anesthetic effect. It can effectively inhibit the release of NO and ET-1, and has higher safety.
