Objective: To investigate the plasma levels of interleukin-6 (IL-6), C-reactive protein (CRP), D-dimer (D-D) and fibrinogen (Fib) among patients with pneumoconiosis, so as to provide insights into the prevention of thrombosis among patients with pneumoconiosis. Methods: Ninety-six male coal workers with stable-stage pneumoconiosis admitted to China Pingmei Shenma Group Occupational Disease Prevention and Control Hospital from February 2019 to February 2021 were included in the pneumoconiosis group, and 43 male healthy volunteers in the hospital during the same period were selected as the control group. The plasma D-D, Fib, IL-6 and CRP levels were detected from subjects in the two groups. The associations of plasma D-D and Fib levels with IL-6 and CRP levels were examined using Pearson correlation analysis among pneumoconiosis patients. Results: Participants in the pneumoconiosis group and the control group had a mean age of (52.91±3.89) and (52.64±4.12) years, D-D of (1.28±0.91) and (0.44±0.11) mg/L, Fib of (4.41±0.98) and (2.88±0.61) g/L, IL-6 of (0.63±0.19) and (0.42±0.06) ng/L and CRP of (3.30±1.65) and (1.35±0.12) mg/L, respectively. Higher plasma D-D, Fib, IL-6 and CRP levels were detected in the pneumoconiosis group than in the control group (all P<0.05). The plasma D-D level correlated positively with IL-6 level among pneumoconiosis patients (r=0.347, P<0.001). Conclusion High plasma IL-6, CRP, D-D and Fib levels are detected among patients with pneumoconiosis, and the plasma D-D level correlates positively with IL-6 level among patients with pneumoconiosis.

Objective To investigate the role of NF-κB in apoptosis of immortalized neural progenitor cells (INPCs) . Methods INPCs were cultured in 6-well plates and were randomly divided into 5 groups ( n = 6 each) : group I was not transfected with any plasmid (group INPC); group Ⅱ was transfected with control plasmid (group INPC/CMV); group Ⅲ was transfected with plasmid RcCMV-p50 (group INPC/p50); group Ⅳ was transfected with plasmid RcCMV-p65 (group INPC/p65) and group V was transfected with plasmid RcCMV-p50 and RcCMV-p65 (group INPC/p50p65). Group INPC/CMV ( H ), INPC/p50 (Ⅲ) and INPC/p65 (Ⅳ) were screened by G418, and the positive clones were then cultured for 3-4 weeks. The transcription of p50 mRNA or p6S mRNA was detected by RT-PCR. The NF-κB activity was measured by luciferase reporter gene assay. The cell apoptosis was measured by annexin V/PI staining. In group INPC/p50p65 and group INPC/p65, the cultured positive clone was transiently transfected with plasmid RcCMV-p50. Two days after transfection, the same measurement was performed in group INPC/pS0p65 and the other groups. Results The expression of p50 mRNA was significantly increased in group INPC/p50 and INPC/p50p65 as compared with the other groups ( P < 0.05) . The expression of p65 mRNA, the NF-κB activity and the apoptotic rate were significantly increased in group INPC/p65 and INPC/p50p65 as compared with the other groups ( P < 0.05). Conclusion Enhanced NF-κB activity can increase immortalized neural progenitor cell apoptosis.

BACKGROUND: Using color Doppler ultrasonography, renal graft size, appearance, structure, and blood flow distribution can be observed. Through the use of blood flow display technique, blood flow perfusion of renal graft can be accurately observed to assist diagnosis and differential diagnosis of complications following renal transplantation. OBJECTIVE: To observe the hemodynamic characteristics during different periods of acute renal transplant rejection, summarize its specific manifestations through analyzing different reaction of two dimensional and color Doppler flow imaging (CDFI) during renal transplantation in order to get valuable index on acute rejection of renal transplantation.DESIGN, TIME AND SETTING: Comparative observation was performed at the Jinan University and First Hospital of Shenzhen University between January 2003 and January 2007.PARTICIPANTS: A total of 299 patients undergoing renal transplantation were divided into normal allograft group (n=236) and acute rejection group (n=63) according to renal allograft function.METHODS: The systolic peak flow rate, end-diastolic flow rate, mean flow rate, pulsatility index and resistance index of main renal artery and arcuate artery in patients of two groups were compared. MAIN OUTCOME MEASURES: Renal allograft arterial inner diameter and hemodynamics of two groups.RESULTS: Compared with normal allograft group, the blood flow perfusion was reduced at acute rejection, which could not reach cortex margin, blood velocity was decreased at the diastolic phase, pulsatility index and resistance index were increased (P < 0.05). CONCLUSION: Color Doppler ultrasound, as a convenient, economical and noninvasive technique, provides the reliable evidences for the renal artery pulsatility index and resistance index in clinic, and also is valuable for the acute rejection early diagnosis of renal allograft.

Objective To evaluate the efficacy and toxicity of the combination of gemcitabine and cisplatin in the treatment of patients with advanced non-small cell lung cancer (NSCLC). Methods A total of 30 cases of non-small cell lung cancer (stages Ⅲ and Ⅳ) were treated with gemcitabine (1 200 mg/m 2, iv infusion, at 1 and 8 d) and cisplatin (100 mg/m 2, iv infusion, at 1 d or cisplatin at 30 mg/m 2, iv infusion, at 1 and 8 d). The administration course was 28 d. Results An objective response was obtained in 46.67% of patients (2 complete and 12 partial responses), whereas 11 patients had no change and 5 patients were progressive. The response rate was 52.38% in patients with no prior chemotherapy and the response rate of 33.33% was achieved in patients who had been given prior treatment. There was significant difference between the two groups (P

OBJECTIVE To investigate the effect of prenatal nicotine exposure on cardiac ejection function and myocardial fibrosis of the offspring of rats.METHODS Pregnant rats were sc given nicotine 6.0 mg· kg-1,once daily for 17 d.The body mass and heart mass of the offspring were detected at the 21th day of gestation,and 15 and 90 d after birth.Heart rate of 90 d offspring was recorded by ECG,and cardiac functions were detected by Doppler ultrasonography,including cardiac output (CO),stroke volume (SV),ejection fraction (EF),left ventricular long axis shortening fraction (FS),interventricular septum diastolic diameter (IVSd) and left ventricular posterior wall diastolic diameter (LVPWd).The myocardial ultrastructure was detected under an electron microscope.Masson staining was used to detect the myocardial collagen fiber deposition.The level of collagen protein type Ⅰ in heart tissue was detected by radioimmunoassay.RESULTS Compared with control group,prenatal nicotine exposure resulted in a decrease of heart mass and body mass in groups of 21 d fetal rats and 15 d offspring(P＜0.05,P＜0.01),but had no effect on the 90 d offspring.Compared with the normal control group,the heart rate of 90 d offspring increased [366+10 vs (418+10) min-1] (P＜0.05),CO,FS and EF decreased (P＜0.01),and IVSd and LVPWd increased (P＜0.05,P＜0.01).Electron microscopy revealed that in the heart of nicotine 90 d offspring,myocardial fiber arrangement was loosened and confused,while extracellular matrix increased.Masson staining showed collagen deposited in the myocardium.The level of collagen type Ⅰ in heart tissue increased [0.59±0.09 vs (0.40±0.05) tμg·g-1 tissue] (P＜0.01).CONCLUSION Prenatal nicotine exposure induces the increased level of cardiac collagen type Ⅰ,myocardial fibrosis and decrease of cardiac ejection function in adult offspring,which may lead to increased susceptibility to cardiovascular diseases.
