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.

OBJECTIVETo explore relationship between HBV DNA level and peripheral blood follicular helper T lymphocyte (Tfh) in patients with chronic hepatitis B (CHB) and its significance.

METHODSHBV DNA levels of 179 cases of CHB patients with positive HBV DNA, positive HBeAg and positive human leukocyte antigen(HLA)-A2 were tested with real time fluorescent quantitative PCR. Tfh and HBV specific CTL were tested with flow cytometry. IL-21 was also tested. 179 cases of CHB patients were divided into group A and group B based on HBV DNA levels, 86 cases in group A, HBV DNA levels were 10(4)-10(5) copies/ml, 93 cases in group B, HBV DNA levels were 10(6)-10(7) copies/ml. Above testing indexes of the two groups were compared.

RESULTSHBV DNA levels of group A were (4.85 +/- 0.37) log10 copies/ml, HBV DNA levels of group B were (6.83 +/- 0.31 ) log10 copies/ml, t = 27.31, P < 0. 001; Tfh of group A was (5.96 +/- 1.59)%, higher than that of group B (3.71 +/- 2.15)%, t = 4.92, P < 0.01; IL-21 of group A was (42.61 +/- 15.11)ng/L, higher than that of group B (14.91 +/- 3.15) ng/L, t = 8.62, P < 0.01; HBV specific CTL of group A was (0.36 +/- 0.08)%, higher than that of group B (0.18 +/- 0.06)%, t = 19.99, P < 0.001.

CONCLUSIONSerum HBV DNA level of CHB patients is related to the level of peripheral blood Tfh level: patients with low HBV DNA level have high Tfh level, high IL-21 level and high HBV specific CTL level. Patients with high HBV DNA level have low Tfh level, low IL-21 level and low HBV specific CTL level. The mechanism of baseline HBV DNA level affecting anti-viral therapy may be related to Tfh level.

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.

OBJECTIVETo observe the therapeutic effect and relevant mechanism of shuxuening Injection (SI) in treating patients with active ulcerative colitis (UC).

METHODSTotally 91 patients with active UC were randomly assigned to 2 groups, 44 in the control group and 47 in the treatment group. Patients in the control group received routine treatment, while patients in the treatment group additionally received intravenous injection of SI (15 mL), twice daily for 14 days in total. Colonoscopy was performed before and after treatment. The therapeutic effect was assessed by Mayo scoring system and the grading of activities evaluated by Baron endoscope. Serum levels of IL-6 and TNF-α were detected by ELISA. The activity of SOD was detected by xanthine oxidase method. The content of MDA was detected by thiobarbituricacid (TBA). Besides, 20 healthy subjects were recruited as the healthy control group.

RESULTSTotally 82 patients completed the study (40 in the control group and 42 in the treatment group). There was no statistical difference in serum levels of IL-6, TNF-α, SOD, MDA, the Mayo score and endoscope grading between the two groups before treatment (P >0. 05). Compared with the healthy control group, serum levels of IL-6, TNF-α, MDA significantly increased (P <0.01), and the serum SOD level decreased (P < 0. 05) in the treatment grup and the control group before treatment. Compared with before treatment in the same group, serum levels of IL-6, TNF-α, MDA, the Mayo score and endoscope grading all decreased in the treatment group and the control group after treatment (P <0. 01, P <0. 05). Compared with the control group after treatment, serum levels of IL-6, TNF-α, MDA, the Mayo score and endoscope grading all decreased (P <0.01, P <0.05), the serum SOD level increased (P <0.05) in the treatment group after treatment. The serum SOD level was obviously negative correlated with serum levels of IL-6, TNF-a, Mayo score, and endoscope score (r = -0. 621, -0.638, -0. 509, -0.787, P <0.01). The serum MDA level was obviously positive correlated with serum levels of IL-6, TNF-α, Mayo score, and endoscope score (r =0.711, 0. 882, 0. 525, 0. 639, P <0.01).

CONCLUSIONSI could improve inflammatory injury and clinical symptoms of patients with active UC, and its mechanism might be associated with antioxidant and scavenging oxygen free radicals.
