Purpose:To investigate the relationship between the expression of NF?B family proteins in ovarian cancer cell lines with chemotherapy resistance of ovarian cell lines. Methods:First, 13 ovarian cancer cell lines were cultured, and then protein was extracted separately from cytoplasm and nucleus. Using Western blotting and MTT chemosensitive testing, the relationship between the expression of NF?B family proteins in ovarian cancer cell lines with chemotherapy resistance of ovarian cell was observed.Results:It was found that the expression of positive rate of P65, P50 and IKB in cytoplasm was 76.9%, 81.8% and 84.6% respectively, and the significant positive expression of P65 and P50 was also found in the nucleus, with a rate of 15.3%, 45.5% respectively. In OV MZ 5 and OV MZ 2774, the expression of P65 was positive and their IC 50 reached a significant value. Conclusions:It was concluded that P50 and P65 affected the growth and development of ovarian cancer cells with the effect of P50 being more obvious. P65 had a close relationship with the chemotherapy resistance of ovarian cancer cells, and thus P65 could be expected to be a new marker in the observation of prognosis.

Respiratory diseases are common in the elderly and often the main causes of death among this population. In addition, it is expected that chronic obstructive pulmonary disease, lower respiratory tract infections, lung cancer, and pulmonary tuberculosis will be listed in the top ten diseases in 2020. Therefore, screening, diagnosis and management of respiratory diseases should be strengthened among the elderly; meanwhile, studies on geriatric respiratory medicine should be further enhanced.

Objective:To investigate the changes of plasma ghrelin levels and insulin(INS) sensitivity of full-term infants small for gestational age (SGA) and the effects of breast feeding on it.Methods:Full-term SGA hospitalised in the Department of Neonatology, Wuhan Children′s Hospital from October 2014 to April 2019 were re-cruited as the SGA group (120 cases), with full-term infants appropriate for gestational age (AGA) born in the same period as the AGA group (96 cases) in this study with recorded birth weight and length.The levels of fasting blood glucose (FG), triglyceride (TG), low density lipoprotein (LDL), high density lipoprotein (HDL), INS and ghrelin were measured 7 days after birth.Homeostasis model assessment-insulin resistance (HOMA-IR) was calculated.The SGA group was subdivided into breast feeding group and formula feeding group.The above indexes were tracked and mea-sured in the 3 rd and 6 th month, respectively, and their growth parameters were recorded. Results:There were no diffe-rences in serum FG, TG, LDL and HDL levels between the SGA and the AGA group (all P>0.05). Compared with the AGA group, the serum INS[(4.21±0.83) mIU/L vs.(3.54±1.10) mIU/L], ghrelin levels[(0.80±0.23) μg/L vs.(0.69±0.19) μg/L] and HOMA-IR (0.85±0.25 vs.0.72±0.25) increased in the SGA group, the differences were statistically significant (all P<0.05). Serum INS, HOMA-IR and ghrelin levels changed with the duration of breast feeding, the differences were statistically significant( F=12.394, 9.810, 5.531, all P<0.05). Conclusions:The serum ghrelin levels of SGA infants increased and INS sensitivity decreased.Breastfeeding can decrease levels of serum INS, HOMA-IR and ghrelin, and can improve INS sensitivity of SGA infants.

Objective To explore the effectiveness of ω-3 fatty acids in intervening rat models of chronic obstructive pulmonery disease (COPD).Methods The rat COPD models were established by cigarette smoking and intratracheal lipopolysaccharide instillation.Totally 90 rats were randomly divided into 3 groups:normal control group (treated with normal saline),COPD group,and intervention group (the COPD rat models treated with ω-3 fatty acids).Lung tissues were obtained on the 7th,21st,and 28th day.The left lower lobes were analyzed to determine the expressions of nuclear factor-kappa beta (NF-κB) and interferon-γ (IFN-γ)and the right lung lobes were sliced for detecting the cell apoptosis.Double antibody sandwich enzyme-linked immunosorbent assay (DAS-ELISA) was used to detect the serum IFN-γ and interleukin-6 (IL-6).Results (1) The pathological changes of lung tissue:there were a large number of inflammatory exudation,alveolar wall thickening,hyperplasia of vascular smooth muscle and the alveolar structure destruction in the COPD model group,but the lung tissue were part of alveolar cavity and a little inflammatory exudate in ω-3 fatty fish acids treatment group,control rats were almost no alveolar inflammation on the 28th days.(2) On the 28th day,NF-κB protein expression of the lung tissue (18.91 ± 3.07) in rats of COPD model group was significantly higher than the control group and the intervention group (5.47 ±4.86 and 7.23 ±2.21) (P ＜0.01).On the 28th day,IFN-γ protein expression in lung tissue of the rats in the model group was 7.12 ±3.37,significantly lower than the intervention group (18.74 ± 2.65),the difference was statistically significant (P ＜ 0.01).(3) The IL-6 levels of the blood-serum of model group rats were (13.43 ± 2.47) ng/L,significantly higher than the control group and the intervention group [(4.78 ± 1.93) and (4.98 ± 1.89) ng/L],the differences were statistically significant (P ＜ 0.01) on the 28th day,,but the IFN-γ level [(2.23 ± 0.63) ng/L] in COPD group was more poorer than ω-3 fatty acids group and the intervention group [(4.51 ± 0.71) and (7.05 ± 0.52) ng/L] (P ＜ 0.01).Conclusions The ω-3 fatty acids can lower NF-κB protein expressions in lung tissues and serum and IL-6 levels in COPD rats; aslo,it can increase the IFN-γ protein expression in lung tissue and serum.Thus,it can prevent the lung inflammation in COPD rats.

Objective To investigate behavior,knowledge and attitude of cigarette smoking,and their relationship among different occupational population in Jiangsu Province.Methods Convenient sampling was used to interview 516 staff from medical institution,schools,government offices,public transportations and waiting rooms,restaurants and internet bars.The content of interview included current smoking,second-hand smoking,and related knowledge and attitude.Results Proportion of current smoking in male(51.2%)was higher than that in female(0.3%,P90%),while it's relatively lower in "second-hand smoking and exact related diseases"(

Objective To improve the diagnosis and treatment of xanthogranulomatous pyelonephri- tis(XGP).Methods The clinical data of 18 cases(5 males and 13 females;mean age,47 years)with XGP were analyzed.Of them,6 had the lesion on the left,and 12 on the right.Before operation,XGP was mis- diagnosed as renal calculus with hydronephrosis in 4 cases,ureteral calculus with severe hydronephrosis in 3 cases,renal tuberculosis in 3 cases and renal carcinoma in 8 cases.Results Of the 18 cases,7 were diag- nosed to have XGP by frozen section during operation and 11 cases had a definite diagnosis by pathological examination after nephrectomy.After a follow-up of 6-124 months,no recurrence was observed in all these 18 cases.Conclusions Preoperative diagnosis of XGP is difficult.This disease is clinically characterized by foam cells in urine smear,low-density value of kidney CT and ineffective antibiotic therapy.Combined a- nalysis of clinical data and improvement of clinical recognition of XGP is the key to avoiding delayed diagno- sis or misdiagnosis of XGP.

Objective To investigate the immunity effects of quorum sensing in the pulmonary infection in rats due to Pseudomonas aeruginosa.Method(1)300 healthy,clean Sprague-Dawley rats were divided into 3 groups randomly:two different Pseudomonas aeruginosa(the wide-type Pseudomonas aeruginosa PAO1 and its double mutant PAO-JP2,in which the quorum sensing systems were defective,embedded in minute seaweed algiante beads which was made by an ejection set with an acuminate hole were inoculated to Sprague-Dawley rats to establish animal model of chronic pulmonary infection.The control group were dealed with the same methods using the sterile brine instead.(2)The levels of antibody IgG,IgM,IgG1,IgG2a to Pseudomonas aeruginosa in sera and cytokines including interferon-?(IFN-?),Interleukin-4(IL-4)in lung homogenate was measured at 3,7,14,28 days after infection.Results(1)The mortality in the PAO1-JP2-infected group(11.0%)was significantly lower than that of the PAO1-infected group(29.7%)and the control group(4.21%).(2) Compared with the PAO-JP2 group,during the early stages of infection(3 days after infection),the IFN-?level in lung homogenates was significantly higher;during the middle stages of infection(7 days after infection),the levels of IFN-?and IL-4 of PAO1-infected rats were significantly higher;In the later stages of infection(14 to 28 days after infection),levles of IFN-?,IgG2a were lower,while levels of IL-4,IgG,IgG1 were higher persistantly in PAO1-infected rats.Conclusions Quorum sensing system play an important role in pathogenesis and immunity effects of pseudomonas aeruginosa infection via modulating the expression of virulence factors and interfering with the immune system of hosts.
