Objective To establish a mice model of cisplatin-induced ototoxicity and to investigate the effect of cisplatin on the expression of caspase-3 in mouse cochlea.Methods Totally 69 Kunming mice were randomly divided into control group,cisplatin 2.5mg/(kg?d) group,cisplatin 3.5mg/(kg?d) group and cisplatin 4.5mg/(kg?d)group.Mice were injected intraperitoneally for 5 days.Auditory brainstem response(ABR) was measured to observe the change of hearing.Envision method of immunohistochemistry was applied to detect the expression of caspase-3 in cochlea.Results The weight and hearing of mice in different dose cisplatin groups were declined significantly as compared with those in control group(P

Aim The effect of N-arachidonoyl ethanolamide(Anandamide,AEA),on the human lung cancer cell A549 was analysed the possible mechanism was detected.Methods To assess the sensitivity of A549 to AEA,A549 cells were exposed to increasing doses of AEA with or without the antagonists to vanilloid receptor 1(VR1) and aspirin.MTT methods were employed to investigate A549 cell proliferation.Results A549 cells exhibited dose-dependent sensitivity to AEA resulting in dramatic cell death.But the effect of AEA on A549 could not be antagonized by the antagonists such as capsazepine and Ruthenium Red.However,cyclooxygenase(COX) inhibitor,aspirin,could attenuate A549 cell death caused by AEA(P

Objective To investigate the expression of osteopontin ( OPN) in epithelial ovarian cancer tissue and its prognostic value. Methods The immunohistochemistry method was used to detect the expression of OPN in 64 cases of epithelial ovarian cancer tissue, and 20 cases with ovarian benign tumors and 10 normal ovarian tissues as well. The relationship between the OPN expression and clinical pathological characteristics and its prognostic value were analyzed statistically. Results The positive expression of OPN case was confirmed in 52 cases in 64 epithelial ovarian cancer. The expression level of OPN in epithelial ovarian cancer tissue was significantly higher than that in benign ovarian tumor and normal control (P <0. 01). The OPN expression in epithelial ovarian cancer tissues was associated with the pathological grading, lymphatic metastasis and production of ascites. The survival time is longer in OPN negative patients than the positive group. Conclusions OPN plays an important role in the tumorgenesis and development of epithelial ovarian cancer and correlates with its prognosis.

Objective:To explore the influence of multidimensional integration and 360° support on the function of family and marriage, and quality of life in women patients with systemic lupus erythematosus.Methods:Totally 196 patients with systemic lupus erythematosus from Department of Rheumatology and Immunology, The Second Affiliated Hospital of the Air Force Medical University from August 2016 to November 2017 were included. According to random number table method, these patients were divided into observation group and control group as 98 cases each. Conventional care and hospital discharge were used for control group. On the basis of this, multidimensional integration and 360° support were used for patients of observation group. The function of family and marriage, quality of life in patients were assessed before and after 3 months of the intervention. The treatment adherence was evaluated in 3 months and 6 months after intervention.Results:Before intervention, the marriage family function score, marital satisfaction, conflict resolution methods and the relationship with friends and family, husband and wife exchange scores of the observation group were (2.3 ± 0.5), (24.6 ± 6.1), (25.7 ± 7.1), (28.2 ± 6.9), (28.8 ± 6.9) points, respectively. Three months after intervention, these scores were (2.5 ± 0.7), (31.6 ± 5.0), (31.7 ± 5.3), (28.1 ± 6.8), (29.0 ± 7.1) points, respectively. There was statistically significant difference between before and after the intervention ( t values were -2.371 - 8.631, P < 0.01). These scores of control group before the intervention were (2.3 ± 0.6), (24.5 ± 6.2), (25.2 ± 7.2), (32.5 ± 6.0), (33.9 ± 6.3) points, respectively. Three months after intervention, these scores were (2.3 ± 0.4), (24.5 ± 6.2), (26.1 ± 6.9), (29.1± 4.8), (28.5 ± 7.2) points. Significant differeces were found between before and after the intervention in control group ( t values were -3.878-6.323, P < 0.05 or 0.01). There was statistically significant difference between the two groups after the intervention ( t values were 2.675-8.631, P<0.01). As for observation group, planning (62.8 ± 27.2 vs. 75.5 ± 25.4) and intimate relationship (62.8 ± 25.2 vs. 78.2± 24.9) in quality of life were obviously difference before and after 3 months of intervention ( t values were 3.050, 3.639, P < 0.01). As for control group, planning (62.5 ± 27.6 vs. 65.7 ± 24.9) and intimate relationship (65.8 ±25.2 vs. 63.5 ± 23.8) in quality of life were obviously difference before and after 3 months of intervention ( t values were 2.375, 3.132, P < 0.01). There was statistically significant difference between the two groups after the intervention ( t values were 3.050, 3.639, P < 0.01). The treatment adherence of observation group was significant better than control group. After 6 months intervention, the treatment adherece of observation group was 83.67% (82/98), while the treatment adherece of control group was 44.89% (44/98), significant differences were found btween the two groups ( χ2 value was 0.511, P < 0.01). Conclusion:Multidimensional integration and 360° support obviously improved function of family and marriage, improved the understanding of disease, and self-management ability of patients. Therefore, it can increase the treatment adherence and improve quality of life in SLE patients.

Objective:To analyse the pathogenic bacteria distribution and clinical characteristics of late-onset sepsis (LOS) among premature infants with gestational age less than 34 weeks in Henan Province.Methods:The clinical data of 6 590 premature infants admitted to 17 medical institutions in Henan Province from January 2019 to December 2020 were retrospectively analyzed. The gestational age of infants was less than 34 weeks and was admitted to the neonatal ward within 7 days after birth. SPSS 19.0 statistical software was used for data analysis.Results:Among 6 590 premature infants LOS developed in 751 cases (11.40%), of whom the diagnosis was confirmed in 276 cases (36.75%) and 475 cases (63.25%) were diagnosed clinically. The fatality rate related to LOS was 13.58%. There were significant differences in the incidence of LOS and infection-related mortality among infants with different gestational ages and body weights ( χ2=388.894 and 13.572, χ2=472.282 and 9.257, P<0.05 or <0.01). Among 276 children with confirmed LOS, 286 strains of pathogenic bacteria were isolated. Gram-negative bacteria were most prevalent (178 strains), accounting for 62.24% of all infections, followed by fungi (58 strains, 20.28%). Klebsiella pneumoniae was most frequently detected Gram-negative bacteria (117 strains, 40.91%), among which 32.48% (38/117) was carbapenem-resistant Klebsiella pneumoniae. The proportion of diagnosed sepsis, the proportion of catheterization, and the infection-related mortality of infants with LOS in tertiary hospitals were all higher than those in secondary hospitals ( χ2=6.212, 5.313 and 4.435, all P<0.05). The proportion of exclusive breastfeeding in secondary hospitals was lower than that in tertiary hospitals ( χ2=19.216, P<0.05). The time of antibacterial drug use before infection in specialized hospitals was longer than that in general hospitals ( χ2=3.276, P<0.05). Conclusion:The incidence of LOS among preterm infants in Henan Province is high, which was mainly caused by Gram-negative bacteria. The clinical characteristics of LOS caused by different pathogens and in different health institutions are different, the prevention and control strategy should be developed accordingly to reduce the incidence LOS of preterm premature infants.
