Objective:To investigate the predictive value of serum thyroid hormone in the short-term prognosis of patients with septic shock..Methods:The 133 patients with septic shock admitted to Intensive Care Unit (ICU) of Nanjing Hospital of Nanjing Medical University were enrolled. Data of patient’s general clinical information, acute physiology and chronic health evaluationⅡ (APACHE Ⅱ), serum triiodothyronine ( T3 ), thyroxine (T4), free triiodothyronine (FT3) , free thyroxine (FT4) and thyroid stimulating hormone(TSH) in 24 h were collected, and the ratio of T3 to FT3 (T3/FT3) was calculated. The patients were divided into the survival group and death group according to the prognosis during ICU hospitalization. Univariate and multivariate analyses were used to analyze the prognostic factors of patients with septic shock. The receiver operating characteristic (ROC) curve and Kaplan-Meier analysis were plotted to evaluate the diagnostic efficacy of serum thyroid hormone for the short-term prognosis of patients with septic shock.Results:Compared to the survival group, FT3, T3 and T3/FT3 were significantly lower in the death group [1.73 (1.54, 2.52) vs. 1.32 (0.94, 1.54) pmol/L, 0.70 (0.56, 0.79) vs. 0.33 (0.25, 0.43) nmol/L, 318.18(299.44, 448.05) vs. 250.00 (192.31, 313.92), respectively; all P < 0.05 ]. The levels of serum T3 and FT3 were significantly correlated with the APACHEⅡ score in patients with septic shock (FT3: r = -0.25, P= 0.004; T3: r = - 0.24, P= 0.006). Binary Logistic regression analysis showed that FT3, T3 and T3/FT3 were independent risk factors of the short-term prognosis of patients with septic shock [FT3: OR = 6.533, 95% CI: 0.687 - 62.157, P = 0.012; T3: OR = 0.529, 95% CI: 0.372 - 0.975, P= 0.000; T3/FT3: OR = 1.719, 95% CI: 1.007 - 1.931, P= 0.002]. ROC curve analysis showed that FT3, T3 and T3/FT3 all had certain predictive value for the short-term prognosis of patients with septic shock, and the diagnostic value of T3 was the largest [AUC = 0.874, 95% CI: 0.794-0.954, P= 0.000]. The Kaplan-Meier curve showed a significantly higher survival rate in patients with T3 greater than 0.535 nmol/L than patients with T3 less than 0.535 nmol/L. Conclusions:The serum levels of thyroid hormone T3 and FT3 are closely related to the severity of septic shock. T3 is an effective ICU mortality during hospitalization prognostic indicator for patients with septic shock, which is better than FT3 and T3/FT3.

Objective:To investigate the predictive value of different glycemic variability indexes within 6 hours on the short-term prognosis of septic shock patients.Methods:A retrospective study was conducted. The 133 patients with septic shock admitted to intensive care unit (ICU) of Nanjing Hospital Affiliated to Nanjing Medical University from December 2014 to December 2019 were enrolled. Patients with septic shock admitted to ICU died during hospitalization were enrolled in the death group and others in the survival group. General data of the patients including gender, age, underlying disease, site of infection, duration of mechanical ventilation, length of ICU stay, whether to use continuous renal replacement therapy (CRRT) and acute physiology and chronic health evaluationⅡ (APACHEⅡ) scores within 24 hours were collected. The blood glucose (GLUadm), mean arterial pressure (MAP), serum creatinine (SCr) and procalcitonin (PCT) were recorded at ICU admission. The patients admitted to ICU received bundle therapy within 6 hours and blood glucose was observed every 2 hours. The blood glucose difference (GLUdif), average blood glucose (GLUave), blood glucose standard deviation (GLUsd) and blood glucose variation coefficient (GLUcv) within 6 hours were calculated. Multivariate Logistic regression analysis was used to analyze the prognostic factors of short-term prognosis of patients with septic shock, and receiver operating characteristic (ROC) curve was plotted to evaluate the diagnostic efficacy of glycemic parameters for short-term prognosis of septic shock patients.Results:A total of 133 patients with septic shock were admitted to ICU, among them 87 patients survived and 46 patients died during the ICU hospitalization. Compared with the survival group, the SCr at ICU admission and APACHEⅡ score within 24 hours were significantly higher in the death group [SCr (μmol/L): 208.5 (143.0, 286.5) vs. 172.0 (91.0, 234.0), APACHEⅡ score: 30.28±6.67 vs. 24.03±5.90, both P < 0.05], the length of ICU stay was shorter [days: 4.00 (2.00, 10.25) vs. 9.00 (4.00, 13.00), P < 0.01]. However, there were no significant differences in the baseline data of gender, age, underlying disease, infection site, CRRT ratio, MAP or PCT at ICU admission between the two groups. Compared with the survival group, the GLUsd and GLUcv within 6 hours in the death group were higher [GLUsd (mmol/L): 2.33 (1.95, 3.14) vs. 2.02 (1.66, 2.52), GLUcv: (31.00±7.06)% vs. (23.31±10.51)%, both P < 0.05]. There were no statistically significant differences in the levels of GLUadm, GLUdif or GLUave within 6 hours between the two groups. Multivariate Logistic regression analysis showed that APACHEⅡ score within 24 hours and GLUsd and GLUcv within 6 hours were independent risk factors of the short-term prognosis of septic shock patients [APACHEⅡ score: odds ratio ( OR) = 1.173, 95% confidence interval (95% CI) was 1.095-1.256, P = 0.000; GLUsd: OR = 1.465, 95% CI was 1.038-2.067, P = 0.030; GLUcv: OR = 1.089, 95% CI was 1.043-1.138, P = 0.000]. ROC curve analysis showed that GLUsd and GLUcv within 6 hours both had certain predictive value for the short-term prognosis of septic shock patients, the area under ROC curve (AUC) of GLUcv within 6 hours was higher than that of APACHEⅡ score (0.765 vs. 0.753), and AUC of GLUsd within 6 hours was close to APACHEⅡ score (0.629 vs. 0.753); and the diagnostic value of GLUsd combined with GLUcv within 6 hours was higher than the two respectively (AUC: 0.809 vs. 0.629, 0.765), the sensitivity was 97.8%, and the specificity was 66.7%. Conclusion:GLUsd combined with GLUcv within 6 hours can be used to estimate the short-term prognosis of septic shock patients.

Objective To investigate the safety of rituximab combination chemotherapy in the treatment of B-cell non-Hodgkin' s lymphoma (B-NHL) complicated with hepatitis B virus (HBV) infection,and assess the incidence of HBV reactivation reduced by prophylactic lamivudine.Methods A retrospective study of HBV-related markers,HBV-DNA and liver function was performed before and after rituximabcontaining treatment in B-NHL patients.Thirty nine B-NHL patients with HBcAb(+)/HBsAb(-) were divided into prophylactic group (14 cases) and control group (25 cases).The incidences of HBV reactivation,functional damage of liver were measured.Results Among the 108 B-NHL patients who received rituximab combinatio nchemotherapy,15 (13.89 ％) were HBsAg (+) and 39 (36.11％) HBsAg (-) / HBcAb (+).Of the 15 HBsAg (+)patients,2 (13.3 ％) experienced reactivation of HBV.The prevalence of HBV reactivation was 7.7 ％(1/13) in patients who received prophylactic antiviral treatment and 50 ％ (1/2) in those who did not receivelamivudine.Among the 39 HBsAg (-) / HBcAb (+) patients,3 cases (7.7 ％) experienced reactivation of HBV.The prevalence of HBV reactivation was 0 in patients who receivcd prophylactic lamivudine treatment and 12 ％ (3/25) in those who did not receive this antiviral drug.Conclusion Prophylactic lamivudine before rituximab combination chemotherapy can reduce HBV reactivation obviously.

Objective To analysis long-term effects and safety of arsenic trioxide (ATO)-based induction and maintenance therapy in newly diagnosed acute promyelocytic leukemia (APL). Methods Retrospective analysis induction remission and post-remission treatment of 62 newly diagnosed APL patients was performed. These cases were followed up for 5 and 7 years. Results The complete remission (CR) rate was similar in ATO/all-trans retinoic acid (ATRA) induction group and ATRA/chemotherapy induction group.However, the former group has the shorter time to CR. The negative rate of PML-RARα fusion gene after induction without ATO was less than that of ATO group (86.2 % vs 56.3 %, P ＜0.05). After CR, the 5-year overall survival (OS) between ATO-base rotation maintenance group and chemotherapy-base rotation maintenance group showed that the former was (94.4±5.4) %, the latter is (45.5±10.2) %; 7-year OS was (52.5±23.7) % and (27.3±9.3) %; 5-year disease free survivals (DFS) was (94.7±5,5) % and (41.3±10.1) %; 7-year DFS was (52.6±23.7) % and (27.5±9.4) %. There was significant different in 5-year or 7-year OS and DFS between two groups (P ＜0.05). The relapse rates of the two groups in post-remission treatment were 14.7 % and 37.0 % (P ＜0.05). Conclusion ATO combined ATRA induction therapy increased the negative rate of PML-RARα fusion gene. ATO-base rotation maintenance improved long-term outcome and decreased the rate of relapse. Furthermore, ATO appeared to be generally safe and well tolerated.

Objective To explore relationship between excursion of blood glucose levels and cognitive performance in diabetic patients over aged 60 years.Methods A total of 108 diabetic patients over aged 60 years were recruited in this study and they wore under continuous blood glucose monitoring system (CGMS) for three days to evaluate excursion of their mean blood glucose (MBG) level and its standard deviation (SD).All the participants accepted cognitive function tests during continuous blood glucose monitoring, including mini mental status examination (MMSE), Montreal cognitive assessment (MOCA) and clock drawing test (CDT).Relationship of the SD of blood glucose level and cognitive performance in the three cognitive tests was assessed.Data were analyzed with CGMS software version 3.0.Results The SD reversely correlated with scores of MMSE (r = - 0.324, P ＜ 0.01 ) and CDT ( r =-0.325, P = 0.001 ), but they did not significantly correlate with MOCA scores (r = -0.212, P =0.081 ).Statistically significant difference was observed between the SD and scores of all three cognitive tests adjusted for glycosylated hemoglobin Alc (HbAlc) level (r = -0.387, -0.046 and -0.292, P =0.029, ＜0.001 and ＜ 0.001, respectively).The SD reversely correlated with scores of MMSE, MOCA and CDT adjusted for MBG (r= -0.314, -0.466 and -0.345, P ＜0.01, respectively).Results of multivariate linear regression analysis showed that the SD reversely correlated to scores of MMSE, MOCA and CDT (β = - 0.378, - 0.224 and - 0.346, all P ＜ 0.05).Conclusions Excursion of blood glucose levels can influence their cognitive performance in diabetic patients over aged 60 years, leading to decrease in their overall cognitive function and activities as its excursion large enough.
