Objective To clarify the role of nuclear factor κB(NF-κB) signaling pathway in pathogenesis of Kashin-Beck disease(KBD) by observing the expression of NF-κB p65 in the whole blood samples of patients with KBD and controls,and the expression of NF-κB p65 in C28/I2 chondrocyte, and to analyze the role of NF-κB p65 molecule in chondrocyte apoptosis. Methods Through a case-control study, 161 patients with KBD (KBD group) were selected from Xunyi, Yongshou, Changwu, Linyou, Qianyang and Long counties in KBD endemic areas and 312 healthy people(control group) were matched by age and sex in Shaanxi Province. Venous blood samples were collected from patients and healthy controls, which were anticoagulated and used for determination of NF-κB p65 protein.According to the group design,the model of C28/I2 chondrocyte oxidative damage was established.The experiments were divided into 4 groups including control group(C), tBHP injury group (O, tBHP 300.00 μmol/L), low selenium pre-protection group (OS1, 0.05 mg/L Na2SeO3+ 300.00 μmol/L tBHP), and middle selenium pre-protection group(OS2, 0.10 mg/L Na2SeO3+ 300.00 μmol/L tBHP). Then, cell apoptosis was detected by Hoechst 33342 and reactive oxygen species (ROS) was detected by dichlorfluorescein(DCF) method. The protein was extracted by Trizol method, then protein expression level of NF-κB p65 molecule was detected by Western blotting in whole blood samples and C28/I2 chondrocyte. Results The differences in age and sex were not statistically significant between KBD group and control group (t = 0.336, P > 0.05; χ2= 0.407, P > 0.05). The protein expression level of NF-κB p65 in KBD group was 1.835 times as high as that of control group (KBD:0.167 ± 0.026, control: 0.091 ± 0.014, t = 5.147, P < 0.01). Under the fluorescence microscope, chondrocyte showed strong blue fluorescence in tBHP group and the level of ROS(1.219 ± 0.104) was higher than those of low and middle selenium pre-protection groups(0.832 ± 0.077, 0.635 ± 0.070, P < 0.05).The protein expression level of NF-κB p65 in tBHP group (1.563 ± 0.351) was higher than that of control group (0.451 ± 0.069, P < 0.05), and protein levels of NF-κB p65 had a decreasing tendency in low and middle selenium pre-protection groups compared to tBHP group. Conclusion The NF-κB signaling pathway is up-regulated in KBD patients, moreover, chondrocyte experiments show that cell apoptosis is mediated via upregulation of NF-κB p65,which suggests NF-κB signaling pathway may play an important role in pathogenesis of KBD.

Objective To investigate the application of peripheral perfusion index (PPI) in early diagnosis and goal-directed therapy of septic shock, and to provide reference for the early clinical diagnosis and treatment of septic shock. Methods A prospective single-blind randomized controlled trial (RCT) was conducted. Adult patients with sepsis admitted to emergency medical department and intensive care unit (ICU) of the First People's Hospital of Lianyungang City in Jiangsu Province from January 2013 to December 2016 were enrolled. The patients were randomly divided into two groups (n = 46). The PPI group was defined using PPI < 1.4 as diagnosis of septic shock standard, and PPI > 2 as treatment guide target. Control group was defined according to the traditional diagnostic criteria of shock which systolic blood pressure was less than 90 mmHg (1 mmHg = 0.133 kPa) or systolic blood pressure value decrease> 40 mmHg baseline and bundle treatment was performed. The volume of fluid resuscitation, organ dysfunction, the sequential organ failure score (SOFA), acute physiology and chronic health evaluationⅡ (APACHE Ⅱ) score,continuous renal replacement therapy (CRRT) time, mechanical ventilation (MV) time, the length of ICU stay and 28-day mortality were observed. Results There were 39 and 27 septic shock patients in PPI group and control group respectively. The diagnostic criteria of traditional septic shock with blood pressure as "gold standard", the sensitivity of PPI < 1.4 for septic shock was 94.3%, the specificity was 28.2%, the authenticity was 66.3%, the positive predictive value was 64.1%, the negative predictive value was 78.6%, the positive likelihood ratio was 1.31, the negative likelihood ratio was 0.18. The per capita fluid replacement within 24 hours in the PPI group was significantly higher than that in the control group (mL: 4 601±1 250 vs. 3 458±1 006, P < 0.01), but there was no significant difference in the per capita volume of the patients diagnosed as septic shock (mL: 4 596±1 320 vs. 4 205±1 058, P > 0.05). Compared with the control group, the PPI group treated patients within 48 hours with less vascular active drugs (cases: 6 vs. 15), APACHE Ⅱand SOFA score were lower (48 hours: APACHE Ⅱ was 10.2±2.1 vs. 12.0±3.2; 72 hours: SOFA was 5.1±1.8 vs. 6.0±2.1, APACHE Ⅱ was 8.9±1.8 vs. 9.8±2.2), the period of CRRT and the length of ICU stay were shorter [the period of CRRT (days): 3.0±0.9 vs. 3.6±1.4, the length of ICU stay (days): 5.2±2.1 vs. 6.3±2.9), the difference was statistically significant (all P < 0.05). There was no significant difference in the liver and kidney function index, arterial blood lactic acid (Lac), MV time (days: 3.3±1.4 vs. 3.5±1.2) and 28-day mortality (15.22% vs. 19.57%) between two groups (all P > 0.05). Conclusions The inadequacy of microcirculatory perfusion by oximetry-derived PPI is more sensitive to the diagnosis of septic shock than hypotension of systemic circulation. With PPI guiding the fluid resuscitation of septic shock patients, vasopressors can be withdrawn earlier and the duration of the CRRT and ICU can be decreased.

Objective: To study the efficacy, safety and long-term outcomes of integrated strategy of bortezomib-based induction regimens followed by autologous hematopoietic stem cell (ASCT) and maintenance therapy in Chinese multiple myeloma (MM) patients. Methods: 200 MM patients receiving integrated strategy of bortezomib--based induction regimens followed by ASCT and maintenance therapy were retrospectively and prospectively analyzed from December 1. 2006 to April 30. 2018. Results: The complete remission rates (CR) and better than very good partial remission rates (VGPR) after induction therapy, transplantation and maintenance therapy were respectively 31% and 75.5%, 51.8% and 87.7%,73.6% and 93.4%. There was no difference between 4 cycles and more than 5 cycles induction chemotherapy. The negative rate of MRD detection by flow cytometry was 17.6% and 38.2% respectively after induction and 3 months after transplantation. The negative rate of MRD gradually increased during the maintenance therapy. The success rate of high dose CTX combined with G-CSF mobilization was 95.5% and transplantation related mortality (TRM) was zero. The median time to progress (TTP) was 75.3 months and the median overall survival (OS) was 99.5 months. TTP of patients obtaining CR and negative MRD after induction were longer that those of no CR and positive MRD. TTP and OS of patients receiving triple-drug induction and ASCT in early stage were longer than those of double-drug induction and ASCT in late stage. LDH≥240 U/L, high risk cytogenetics, ISS II+III stage and HBsAg positive were prognostic factors at diagnosis. However, only MRD and high risk cytogenetics were independent prognostic factors after transplantation and maintenance therapy. The clinical characteristics of patients of TTP ≥6 years were listed below: light-chain type M protein, ISS I stage, normal level of hemoglobin and platelet, normal LDH, HBsAg negative, chromosome 17p-negative, good response and sustained good response. Conclusions Integrated strategy of bortezomib-based induction regimens followed by ASCT and maintenance therapy can significantly improve the short-term and long-term efficacy. The prognostic factors of TTP in different disease stages were different. Response to treatment, especially MRD, played a more important role in prognostic factors.

Objective:To analyze the risk factors of bronchopulmonary dysplasia(BPD)in very preterm infants(VPI), and to provide scientific basis for the prevention and treatment of BPD in VPI.Methods:A prospective multicenter study was designed to collect the clinical data of VPI in department of neonatology of 28 hospitals in 7 regions from September 2019 to December 2020.According to the continuous oxygen dependence at 28 days after birth, VPI were divided into non BPD group and BPD group, and the risk factors of BPD in VPI were analyzed.Results:A total of 2 514 cases of VPI including 1 364 cases without BPD and 1 150 cases with BPD were enrolled.The incidence of BPD was 45.7%.The smaller the gestational age and weight, the higher the incidence of BPD( P<0.001). Compared with non BPD group, the average birth age, weight and cesarean section rate in BPD group were lower, and the incidence of male infants, small for gestational age and 5-minute apgar score≤7 were higher( P<0.01). In BPD group, the incidences of neonatal respiratory distress syndrome(NRDS), hemodynamically significant patent ductus arteriosus, retinopathy of prematurity, feeding intolerance, extrauterine growth restriction, grade Ⅲ~Ⅳ intracranial hemorrhage, anemia, early-onset and late-onset sepsis, nosocomial infection, parenteral nutrition-associated cholestasis were higher( P<0.05), the use of pulmonary surfactant(PS), postnatal hormone exposure, anemia and blood transfusion were also higher, and the time of invasive and non-invasive mechanical ventilation, oxygen use and total hospital stay were longer( P<0.001). The time of starting enteral nutrition, cumulative fasting days, days of reaching total enteral nutrition, days of continuous parenteral nutrition, days of reaching 110 kcal/(kg·d) total calorie, days of reaching 110 kcal/(kg·d) oral calorie were longer and the breastfeeding rate was lower in BPD group than those in non BPD group( P<0.001). The cumulative doses of amino acid and fat emulsion during the first week of hospitalization were higher in BPD group( P<0.001). Multivariate Logistic regression analysis showed that NRDS, invasive mechanical ventilation, age of reaching total enteral nutrition, anemia and blood transfusion were the independent risk factors for BPD in VPI, and older gestational age was the protective factor for BPD. Conclusion:Strengthening perinatal management, avoiding premature delivery and severe NRDS, shortening the time of invasive mechanical ventilation, paying attention to enteral nutrition management, reaching whole intestinal feeding as soon as possible, and strictly mastering the indications of blood transfusion are very important to reduce the incidence of BPD in VPI.
