Objective:To explore the related factors of postoperative adjuvant therapy for cervical cancer stagedⅠB1-ⅡA2 [according to 2018 International Federation of Gynecology and Obstetrics (FIGO) staging standard], and to establish a nomogram model to predict the risk of postoperative adjuvant therapy for locally advanced cervical cancer.Methods:A total of 714 patients with cervical squamous cell cancer staged FIGO ⅠB1-ⅡA2 treated by surgery in Anhui Provincial Hospital were selected as the research objects from January 2009 to December 2019, and their clinicopathological data were analyzed. Multiple logistic regression analysis was used to determine the influencing factors, and a nomogram model was established to predict the risk of postoperative adjuvant treatment of cervical cancer. The predictive performance of the model was evaluated with the consistency index (C-index), and the compliance of the model was evaluated with the calibration curve.Results:Univariate analysis suggested that postoperative adjuvant therapy for cervical cancer was associated with gravidity ( χ2=11.506, P=0.001), underlying disease (hypertension or diabetes) ( χ2=7.668, P=0.006), squamous cell cancer antigen (SCC-AG) level ( χ2=19.392, P<0.001), imaging risk factors ( χ2=16.392, P<0.001), FIGO stage ( χ2=25.686, P<0.001), tumor size ( χ2=9.392, P=0.025) and surgical path ( χ2=16.590, P<0.001). Multivariate logistic regression analysis suggested that the number of pregnancy >2 times ( OR=1.951, 95% CI: 1.355-2.808, P<0.001), SCC-Ag ≥1.5 μg/L ( OR=2.021, 95% CI: 1.444-2.829, P<0.001), FIGO stage ⅠB3-ⅡA2 [ⅠB3 ( OR=1.933, 95% CI: 1.139-3.282, P=0.015); ⅡA1 ( OR=2.723, 95% CI: 1.556-4.765, P<0.001); ⅡA2 ( OR=3.159, 95% CI: 1.502-6.646, P=0.002)], with underlying disease (hypertension or diabetes) ( OR=1.867, 95% CI: 1.051-3.318, P=0.033), imaging risk factors ( OR=1.997, 95% CI: 1.127-3.537, P=0.018), without neoadjuvant therapy [preoperative neoadjuvant therapy for 1 cycle ( OR=0.402, 95% CI: 0.207-0.783, P=0.007)] and laparoscopic surgery ( OR=2.177, 95% CI: 1.524-3.112, P<0.001) were independent influencing factors for postoperative adjuvant treatment of cervical cancer. Based on the screened variables, the nomogram model to predict the risk of postoperative adjuvant treatment for cervical cancer has good predictive performance (C-index was 0.702) and compliance. Conclusion:The number of pregnancy >2 times, SCC-Ag ≥1.5 μg/L, FIGO stage ⅠB3-ⅡA2, with underlying disease (hypertension or diabetes), imaging risk factors, without neoadjuvant therapy, and laparoscopic surgery are independent influencing factors for postoperative adjuvant treatment of cervical cancer. A nomogram model has been constructed to predict the risk of postoperative adjuvant therapy for locally advanced cerrical cancer, and it can provide evidence for clinical treatment selection.

Objective To evaluate the effect of global end diastolic volume index (GEDVI) on fluid resuscitation in elderly patients with septic shock. Methods A prospective randomized controlled trial (RCT) was conducted. Septic shock patients over 65 years admitted to intensive care unit (ICU) of Shandong Province, Zibo Central Hospital from January 2013 to December 2015 were enrolled. The patients were randomly divided into control group and observation group, 20 cases in each group. In accordance with the guidelines for the treatment of septic shock, early goal-directed therapy (EGDT), rehydration in the control group was treated with the guide of central venous pressure (CVP); observation group was received pulse indicator continuous cardiac output (PiCCO) monitoring, and rehydration was treated according to the GEDVI and extravascular lung water index (EVLWI), i.e. GEDVI was maintained in 650-800 mL/m2, EVLWI was not obviously increased compared with the basic value and without the emphasis of CVP. Initial acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ ) score, sequential organ failure score (SOFA), procalcitonin (PCT), mean arterial pressure (MAP), lactic acid (Lac) and oxygenation index (PaO2/FiO2); serial Lac, central venous to arterial carbon dioxide pressure (Pcv-aCO2), fluid balance, the amount of noradrenaline accumulation, PaO2/FiO2 after 6, 24 and 48 hours resuscitation; mechanical ventilation time, incidence of acute heart failure, ICU hospitalization time and 28-day mortality were recorded. Results There was no significant difference in gender,age, APACHE Ⅱ score, SOFA score, primary disease, infection site and basal PCT, MAP, Lac, PaO2/FiO2 between the two groups. Compared with the control group, 6 hours Lac, Pcv-aCO2 recovery, positive fluid balance, noradrenaline accumulation and PaO2/FiO2 of the observation group showed no significant difference; positive fluid balance 24 hours in the recovery was significantly reduced (mL: 2919.80±986.44 vs. 3991.40±933.53), Pcv-aCO2 significantly decreased [mmHg (1 mmHg = 0.133 kPa): 5.55±1.43 vs. 7.10±2.38], PaO2/FiO2 significantly improved (mmHg: 194.80±28.57 vs. 177.65±23.46), and noradrenaline accumulation was increased significantly (mg: 40.99±20.69 vs. 27.31±19.34) with statistically significant difference (all P < 0.05); the blood level of Lac 48 hours in the recovery was significantly decreased (mmol/L: 1.16±0.89 vs. 1.85±1.01), Pcv-aCO2 (mmHg: 5.35±1.18 vs. 6.70±2.34), and PaO2/FiO2 (mmHg: 215.75±33.84 vs. 190.60±32.89) were further improved, the positive fluid balance was significantly reduced (mL: 3141.55±1245.69 vs. 4533.85±1416.67, all P < 0.05). Compared with the control group, mechanical ventilation time (days: 3.65±1.31 vs. 4.50±1.19), ICU hospitalization time (days: 5.80±1.67 vs. 7.15±2.30) was significantly shorter in the observation group (both P < 0.05), acute heart failure rate was decreased significantly (5.0% vs. 30.0%, P < 0.05), but the 28-day mortality showed no statistical significance (25.0% vs. 40.0%, P = 0.311). Conclusions Compared to the conventional EGDT methods, fluid resuscitation under the guidance of GEDVI in elderly patients with septic shock with less liquid loading, can achieve better oxygenation and reduce heart failure, shorten the duration of mechanical ventilation and ICU stay, and play an important significant guidance for elderly patients' fluid resuscitation with septic shock.

Objective To compare the rates of regimen modification between patients with different initial antiretroviral therapy, and to investigate risk factors associated with drug toxicity-related regimen modification.Methods A two-years retrospective cohort study was conducted in 14 060 patients who initiated antiretroviral treatment with Zidovudine (AZT)/Tenofovir disoproxil (TDF)+Lamivudine (3TC)+Efavirenz (EFV) since 2012.There were 5 126 patients initiated TDF+3TC+EFV therapy (TDF group) and 8 934 patients initiated AZT+3TC+EFV therapy (AZT group).Chi-square test was used to compare the rate of first-line regimen modification and the rate of toxicity-related regimen modification between two groups.Cox proportional hazard model was used to investigate the risk factors associated with regimen modification.Results A total of 14 060 acquired immunodeficiency syndrome patients were observed for a median period of 1.85 person-years.There were 2 795 patients who changed their initial antiretroviral regimen and the rate of initial regimen modification was 19.9%.Two hundred patients who changed their initial regimen due to pregnancy were excluded.There were 2 070 patients in AZT group who changed their initial regimen with a rate of 23.5%.Among them, 1 652 patients changed their regimen due to drug toxicity and the rate was 18.8%.There were 525 patients in TDF group who changed their initial regimen with a rate of 10.4% and the rate of toxicity-related regimen modification was 6.2%.The differences between two groups were statistical significance (χ2=366.68 and 416.89, respectively, both P<0.01).The risk of regimen modification in AZT group were significantly higher than that in TDF group (aHR=2.89, 95%CI: 2.57-3.24).The risk of toxicity-related regimen modification in AZT group was also significantly higher than that in TDF group (aHR=3.85, 95%CI: 3.34-4.45).Conclusions Patients initiated antiretroviral treatment with AZT+3TC+EFV are more likely to change their initial regimen than those who initiated treatment with TDF+3TC+EFV.Female, age >45 years old, BMI<18.5 kg/cm2 and baseline CD4+ T cell count<200/mL were risk factors associated with regimen modification.
