Objective: To investigate the expression of Bcl-2 and Bax in renal tissues of patients with hepatitis B virus-associated glomerulonephritis (HBV-GN). Methods: Twenty HBV-GN specimens with complete nephrology data and 10 normal renal specimens were randomly chosen for the present study. Cell apoptosis was detected by means of terminal deoxynucleotidyl transferase mediated d-UTP nick end labeling (TUNEL) and the apoptotic index was calculated; immunohistochemistry was used to detect the protein expression of Bax and Bcl-2. Results: The apoptotic index in HBV-GN group was obviously higher than that of the control group; the apoptotic cells were mainly distributed in the proximal and distal renal tubules and the collecting duct epithelial cells, seldom seen in the glomerular cells. The expression of Bcl-2 in HBV-GN patients was predominately present in the renal tubular epithelia cells (positive in the plasma, membrane and nuclear); the expression of Bax was found in both glomerular cells and renal tubular cells, mainly in tubular epithelial cells, seldom seen in Bowman's capsule or glomerular mesangial region. Conclusion: Apoptosis in the kidney of HBV-GN patients mainly occurs in the renal tubular epithelial cells; expression of Bax and Bcl-2 is mainly in the renal tubular epithelial cells, suggesting that the injury of tubular interstitial damage may be one of the important factors for the development of HBV-GN.

The mechanism of long chain non-coding RNA (lncRNA) is diverse. LncRNA can regulate the expression of genes at multiple levels and is closely related to some pathological process, such as tumor formation, viral replication, inflammatory damage, etc. The abnormal expression of lncRNA is involved in the patho-physiological changes of the disease, and plays a key role in many links, such as the stability of mRNA, the regulation of translation level, protein transport, RNA processing and modification, and so on. The development of sepsis inflammatory injury is a complex process involving multiple genes and pathways, in which the abnormal structure and expression of many encoding genes or non-coding genes exist.This paper review the research progress on lncRNA in the regulation of chondriokinesis, pro-inflammatory cytokines, calcium ion transport, nuclear factor-κB (NF-κB) in signal pathway and other inflammatory lesions, which may provide a new method for the diagnosis and treatment of sepsis.

Since the oral rehydration salts solution(ORS) has been used to treat acute diarrhea of children, there are different kinds of ORS in order to satisfy the need of clinical work. They are the initial WHO-ORS, other substances-supplemented ORS and the reduced osmolarity ORS, each of which has their own efficiency and advantage.

Objective To know the primary effect of nutrition intervention in farmers. Methods The questionnaires were used to do baseline and evaluation survey. The intervention ways were used in trial group, including holding lectures, posting posters, sending out healthy material, quizzes with prizes, recommending salts low in sodium to each family, training to make healthy food by the chef; but there were no measures in control group. Results There were statistical significance in healthy awareness of nutrition, exercises and chronic diseases between two groups after intervention; However, the average intake amounts of vegetables did not reach the recommendation of diet guidelines; After intervention, the intake frequency of vegetables and fruits had statistical significance between before and after intervention in trial group, and also had statistical significance in two groups. Conclusion The awareness of healthy knowledge and attitudes has been obvious improvement, but the diets and life styles of farmers have no obvious change. The diet structure and behavior of farmers have been increasingly rational but not enough. The farmers have started to increase the intake times of vegetables and fruits and built up the conception of eating more vegetables and fruits.

Objective To study the diagnostic value of cavernosography in the venous leakage impotence.Methods Cavernosography were performed for 25 patients with the venous leakage impotence who had been diagnosed by the clinic just after the contrast agent had been injected.The appearance of cavernosography were analysed.Results Different degree venous leakage had been shown in 25 cases.The diagnostic accordance rate of the cavernosography,clinic impotence for the venous leakage was 100%(25/25).The accordance rate of the degree of the venous leakage shown by the cavernosography and pointed out by the clinical impotence was 36%(9/25).Conclusion Cavernosography not only can show the venous leakage and its location,but also can know the degree of the venous leakage.

Objective To investigate the efficacy of docetaxel combined with capecitabine in the treatment of patients with locally advanced breast cancer and its effect on immune function.Methods 160 patients with locally advanced breast cancer were randomly divided into observation group and control group.The control group was treated with capecitabine.The patients in the observation group were treated with docetaxel combined with capecitabine.The clinical effective rate, median time to progress, median survival time, one year survival rate and immunoglobulin protein expression levels were observed.Results The clinical effective rate and stable rate in the observation group were 88.75% and 95.00%, which were significantly higher than 68.75% and 87.50% in the control group, the differences were statistically significant (x2=5.89,4.17,all P<0.05).After treatment, the median time to progression, median survival time and one year survival rate of the observation group were significantly higher than those of the control group (t=3.43,5.09,6.23,all P<0.05).Compared with before treatment, after treatment, the IgG,IgM and IgA levels in the observation group significantly decreased(t=2.34,3.16,3.27,all P<0.05), while those of the control group were not significantly changed (t=0.79,0.22,0.27,all P>0.05).Conclusion Docetaxel combined with capecitabine in the treatment of patients with locally advanced breast cancer can improve the clinical efficacy and stability, prolong the survival time of patients.Compared with using single agent chemotherapy, combined use has no significant effect on human immune function, the effect is better than the use of capecitabine alone, which is worthy of promotion in clinical use.

Objective To investigate the normal aortic valve histological manifestation and histopathological changes of degenerative aortic valve.Methods In Tianjin Chest Hospital,there were patients due to aortic valve disease undergoing aortic valve replacement surgery in the Department of Cardiovascular Surgery,and in 22 cases,their pathological aorta tricuspid valves were successfully excised from May 2009 to May 2010.The aortic valve tissues were collected,and according to hematoxylin and eosin (HE) staining of the degenerative calcified aortic valves with stenosis,they were divided into pathological valvular calcification locus group and non calcification locus group.Six morphologically normal aortic valve tissues were taken as a control group.The situation of collagen fibers,elastic fibers and collagen content in normal and disorder valves were analyzed by using of IDA-2000 high definition color medical image analysis system.Results With the naked eye,the thickness of the valve leaves with stenosis was increased,and at the valve leaf close to the side of arota,calcified foci were produced.Under light microscope,inflammatory changes were found in the aortic valve endothelium,in the tubular wall,there were aggregations of newly formed capillary with relatively thin wall,cholesterol crystals,cells similar to foam cells and diffuse and nodular calcification commonly seen,Compared with the normal valve,the ratio between collagenous and elastic fibers no matter at calcified or non-calcified region was greater in pathological valve [(3.19-± 1.01)％,(2.62-± 0.34)％ vs.(1.89-± 0.29)％,both P ＜ 0.05],collagen content (ratio =collagen/valve area) was also higher [(65.17 ± 11.48)％,(39.25-± 11.15)％ vs.(22.99 ± 4.78)％,P ＜ 0.05] in pathological valve,and the changes in calcified region were more significant than those in non-calcified region (both P ＜ 0.05).Conclusions Proliferation of collagen and degradation of elastic fibers are obvious in degenerative aortic valve,and the changes are more prominent at calcified region.

Objective To examine the impact of oncology nurses' compassion satisfaction and compassion fatigue on doctor-patient relationship satisfaction.Methods Questionnaire survey was conducted by 388 oncology nurses,the questionnaires include Professional Quality of Life Scale and DoctorPatient Relationship Satisfaction Scale.Results The total scores of compassion satisfaction was 34.22±7.19,the total scores of secondary traumatic was 26.32±6.12,the total scores of job burnout was 25.13±6.08,the total scores of doctor-patient relationship satisfaction was 4.24±0.75.Pearson correlation analysis showed that doctor-patient relationship satisfaction score was positively correlated with oncology nurses' compassion satisfaction (r=0.468,P ＜ 0.05),negatioely correlated with nurses' compassion fatigue factor scores (r=-0.182,-0.531).Regression analysis showed that compassion satisfaction,secondary traumatic,job burnout and night shift frequency were influencing factors of doctor-patient relationship satisfaction,which could explain29.2％ of the variance.Conclusions Improvement of the oncology nurses' compassion satisfaction and compassion fatigue can improve the doctor-patient relationship satisfaction and the quality of nursing service,and create a harmonious medical environment.
