Objective To study the concentrations of endocrine disrupting compounds in reclaimed water samples. Methods A solid-phase extraction (SPE)-gas chromatography (GC)-mass spectrometry (MS) analytical method was used for the separation and determination of endocrine disrupting compounds (EDCs) from water samples. The water samples were collected from each process of the reclaimed water plant of Tianjin, China. Important and contrasting EDCs including estrone (E1), 17?-estradiol (E2), 17?-ethynylestradiol (EE2), 4-tert-octylphenol (OP), 4-nonylphenol (NP), bisphenol A (BPA), di-n-butyl phthalate (DnBP), diisobutyl phthalate (DIBP), and di (2-ethylhexyl) phthalate (DEHP) were selected as the target compounds. C-18 solid-phase extraction (SPE) technique was used for the extraction recoveries of target compounds from water samples while ethyl acetate was efficient in eluting EDCs from SPE cartridges. After elution from the SPE column, the t-butyldimethylsilyl (TBS) derivatives of EDCs with N-methyl-N-(tertbutyldimethylsilyl) trifluoroacetamide (MTBSTFA) were analyzed by GC-MS in the selected ion mode (SIM). Results Concentrations of steroid hormones, phenolic compounds and phthalate esters ranged from not detected to 7.01 ng/L, 4.85 ng/L, and 0.03 ?g/L to 23.82 ?g/L, respectively. Conclusion Environmental endocrine disrupting compounds are not completely removed in the process of reclaimed water treatment and will be carried over into the general aquatic environment as it will be reused.

Objective: To evaluate the surgical results of aortic regurgitation caused by aortitis. Methods: Results: Between 1990 and 2002, 20 patients with aortic regurgitation caused by aortitis underwent surgery. The surgical procedures included aortic valve replacement in 12 patients and aortic root replacement in 8 (Bentall type operation in 5, Cabrol type operative in 2, and David type operation in one). Conclusion: There was no operative death. The follow-up duration ranged from 2 to 61 months (mean, 24 months). Postoperative perivalvular leakage and/or detachment of the prosthetic valve occurred in 7 patients after aortic valve replacement. 7 patients required re-operation, and 3 patients underwent third operation due to perivalvular leakage. There were 4 later deaths (20%). Conclusion: The timing for the operation, selection of operative procedure, and preoperative control of active inflammation were essential for successful treatment of aortic regurgitation caused by aortitis.

Objective To observe the effect of Shenfu injection on fluid intake volume of resuscitation therapy for patients with septic shock. Methods The clinic data of 36 patients with septic shock admitted to Department of Critical Care Medicine of the Affiliated Hospital of Hangzhou Normal University from June 2010 to June 2013 were retrospectively analyzed. All the patients were treated with western conventional medicine. Twenty cases treated with western medicine combined with Shenfu injection (intravenous drip 100 mL once daily, half of a month was a therapeutic course) were defined as Shenfu group; the rest 16 cases treated with western medicine only were assigned as control group. The following data after treatment for 6, 24, and 72 hours in the two groups were compared:liquid intake and urine volumes, system vascular resistance index (SVRI), mean arterial pressure (MAP), cardiac index (CI), and case fatality rate in 28 days. Results There were no significant differences in the liquid intake volume in 6 hours after treatment (mL:3 101±219 vs. 3 329±295, P>0.05), the urine volumes in 6, 24 and 72 hours after treatment (mL, 6 hours:701±229 vs. 651±292, 24 hours:1 870±566 vs. 1 697±618, 72 hours:7 396±2 546 vs. 5 987±2 497), and the levels of SVRI in 24 hours after treatment between Shenfu group and control group (kPa·s·L-1·m-2:802±158 vs. 741±106, all P>0.05). The total liquid intake volumes (mL) in 24 hours and 72 hours after treatment in Shenfu group were significantly less than those in the control group (24 hours:4 544±425 vs. 4 996±396, 72 hours:10 985±891 vs. 11 612±807, both P<0.05). The SVRI, MAP, and CI in 72 hours of Shenfu group were significantly higher than those of control group [SVRI (kPa·s·L-1·m-2): 1 361±182 vs. 1 163±183, MAP (mmHg, 1 mmHg = 0.133 kPa): 76.2±6.1 vs. 71.8±6.3, CI (mL·s-1·m-2):76.2±7.5 vs. 70.8±7.2, all P<0.05], and the 28-day mortality rate in Shenfu group was significantly lower than that of control group [25.0%(5/20) vs. 62.5%(10/16), P<0.05]. Conclusion The application of Shenfu injection was favorable to the reduction of liquid intake volume in 72 hours after treatment that may be beneficial to the fluid limitation management in the course of treatment for septic shock.

Objective:To investigate the protective effect of ulinastatin on sepsis-acute kidney injury (SA-AKI) by NF-κB signaling pathway.Methods:Total of 60 mice were randomly(random number) divided into sham group, cecal ligation puncture group (CLP group) and ulinastatin treatment group (CLP+UTI group). Ulinastatin treatment group was intraperitoneally injected with ulinastatin 50 000 U/kg once a day. 24 hours after operation, five mice were sacrificed, the kidney tissues were collected to observe renal histopathology by HE staining. The macrophage infiltration was observed by immunohistochemistry. The remaining mice in each group were used to calculate the survival rate of 7-day after operation. HK-2 cells were stimulated by LPS to obtain the SA-AKI model, and the cells were divided into control group, LPS group and LPS + UTI group. CCK-8 assay was used to detect cell viability, EdU assay was used to detect cell proliferation, and JC-1 assay was used to detect mitochondrial damage. The phosphorylation degree of NF-κB was detected by western blot. Inflammatory factors concentrations of cellular supernatant were detected by ELISA assay.Results:Compared with the sham group, the kidney tissue of mice in CLP group showed that kidney pathological obvious changed, the infiltration of macrophages increased, and the survival rate of mice decreased. CLP+ UTI group reduced the pathological changes and the infiltration of macrophages, improved the survival rate of mice. Compared with control group, LPS group obviously inhibited the cells activity and proliferation of HK-2 cells, damaged the mitochondrial membrane potential of HK-2 cells. Compared with LPS group, LPS+ UTI group attenuated the phosphorylation of NF-κB, decreased the secretion of inflammatory factors, rescued the activity and proliferation of HK-2 cells, and reduced the damage of HK-2 mitochondrial membrane potential.Conclusions:Ulinastatin can reduce mitochondrial damage, inhibit the secretion of inflammatory factors and improve the function of renal tubular epithelial cells through regulating NF-κB signaling pathway.

Objective:To retrospectively analyze the gender differences in the clinical characteristics and perioperative outcomes of patients with type A aortic dissection in our institution.Methods:From January 2019 to January 2020, total 405 patients underwent surgical treatment for type A aortic dissection at Beijing Anzhen Hospital, including extensive aortic repair (total aortic arch replacement combined with stenting elephant trunk implantation) and limited aortic repair. In the entire cohort, male 295 cases, female 110 cases. All measures in this study were expressed as ± s or median(quartiles) and analyzed by Student t test for variables or non- parametric tests; count data were expressed as frequencies and percentages and analyzed by χ2 test and Fisher exact probability test. Independent risk factors were analyzed by logistic multivariate regression. Results:Females were older than males[(53.3 ± 12.4)years old vs. (47.1 ± 11.0)years old, P<0.001] and had significantly higher proportion of diabetes(9.1% vs. 4.1%, P=0.047) and previous cerebrovascular disease (11.8% vs. 5.8%, P=0.038). Females had a lower proportion of total aortic arch replacement combined with elephant trunk implantation (64.5% vs. 82.7%, P<0.001), while aortic cross-clamp time[168.0(144.8, 201.5) minutes vs. 190.0 (163.0, 217.0) minutes, P<0.001] and CPB time[99.0 (79.8, 118.0) min vs. 107.0 (91.0, 126.0) min, P=0.006] were significantly shorter than males. Females had significantly higher rates of pulmonary infection (14.5% vs. 5.8%, P=0.004) and stroke than males (15.5% vs. 8.1%, P=0.030). The difference in the proportion of postoperative deaths between female and male TAAD patients was not statistically significant (3.6% vs. 7.8%). Logistics multivariable regression analysis found that female was an independent risk factor for postoperative stroke ( OR=2.574, 95% CI: 1.198-5.531, P=0.015) and pulmonary infection ( OR=2.610, 95% CI: 1.180-5.772, P=0.018). Conclusion:Gender did not affect mortality after TAAD repair significantly, but females increased the risk of stroke and pulmonary infection after TAAD surgery.

Objective:To investigate the differences in outcomes of surgical strategies and prognosis of patients with acute type A aortic dissection(ATAAD) during the period of COVID-19 Omicron variant epidemic compared with the non-epidemic period.Methods:Clinical data were retrospectively collected from ATAAD patients during the COVID-19 Omicron variant epidemic(December 7, 2022 to January 10, 2023) and during the non-epidemic period(December 7, 2019 to January 10, 2020) to compare the differences in surgical strategies, perioperative mortality, and perioperative complication rates in ATAAD patients during the two different periods.Results:There were 14 patients in the COVID-19 infected group and 43 patients in the control group. Patients in the infected group had a shorter mean aortic clamp time[(89.71±16.27)min vs.(110.09±28.99)min, P<0.01], a significantly higher postoperative mortality rate relative to the control group(21.43% vs. 2.33%, P=0.02), a significantly longer length of stay in the ICU(3 days vs. 2 days, P=0.04) and the duration of intubation time(34 h vs. 14 h, P<0.01), and the incidence of adverse events, mainly cerebral infarction, was higher in infected group(28.57% vs. 6.98%, P=0.03). Conclusion:During the COVID-19 Omicron variant strain epidemic, our center preferred a more conservative surgical strategy in COVID-19 infected patients. Although the COVID-19 infection increased the postoperative mortality and complication rate of ATAAD, patients still achieve a more satisfactory outcome. Therefore, surgical treatment should be timely performed for ATAAD patients.
