Objective To investigate the efficacy of ozone water in the treatment of incontinence dermatitis. Methods 23 cases of incontinence dermatitis were divided into control group, silver ion group and experimental group respectively. Each group consists of 41 cases. The patients were treated with Zinc oxide ointment in control group, ionic silver dressing in silver ion group and activity of ozone water treatment in experimental group. Healing time and curative effect, as well as satisfaction assessment of patients after treatment were studied. Results It showed that both silver ion group and experimental group achieved an effective rate of 100%. The healing time of experimental group and silver ion group were relatively similar, while that of control group is significant differentt (P<0.05). Satisfaction assessment showed that the experimental group after treatment was 100%, while silver ion group was 90.24% and 60.98% in the control group. Results showed that experimental group is better than that of silver ion group, and both groups were statistically significant different to control group (P<0.01). Conclusion The use of ozone water in the treatment of incontinence dermatitis can not only effectively improve the wound healing ability, shorten the healing time, but also is convenient, safe and low cost.

Objective To study the application of low-dose scan of multidetector row CT(MDCT)in the chemotherapy of infiltrative tuberculosis. Methods 100 patients with infiltrative pulmonary tuberculosis who were under treatment were selected. All patients accepted conventional-dose and low-dose scan of MDCT. The image quality and treatment effect of two groups were compared. Results The image quality on lung window of two groups did not differ significantly(P＞0.05). The image quality on lung window with multiplanar reconstruction of two groups also did not differ significantly(P＞0.05). The image quality on soft-tissue window differed significantly (P<0.05). The ED, DLP and CTDIvol of the low-dose group were significantly lower than those of the conventional-dose group. Conclusion For MDCT follow-up examination of patients with infiltrative tuberculosis, the image quality on lung window with low dose is similar to the image quality with conventional dose. It may effectively reduce the exposure dose of CT examination. This cost-effective modality not may can meet the curative effect evaluation of TB, but also can improve the security of the follow-up examination of patients.

Objective To construct a gemcitabine-resistant variant of the breast cancer cell line (4T1/Gem) and establish a nude mouse model of breast cancer with hepatic metastatic. Methods A gemcitabine-resistant variant of the breast cancer 4T1 cell line was induced by gradually increasing the concentration of gemcitabine; this variant is referred to in this study as 4T1/Gem. The proliferation suppression rates of 4T1 and 4T1/Gem cells were determined by using the CCK-8 essay to evaluate the drug resistance indices of the cell lines. Western blot analysis was used to detect P-gp protein expression. Under ultrasonography, a 4T1/Gem cell suspension was injected into nude mice to induce liver tumors. H&E staining was used to observe tumor pathology, and immunohistochemistry was used to detect the expression of ER, PR, HER-2, Ki-67, and P-gp. Results After 14 months of induction, a 4T1/Gem cell line is established successfully. The cell line can grow stably in culture liquid containing 40 μg/ml gemcitabine. The drug resistance index of 4T1/Gem is 788.547. Compared with the 4T1 cell line, the 4T1/Gem cell line can upregulate P-gp protein expression and successfully establish a nude mouse model of breast cancer with hepatic metastatic. ER, PR, and HER-2 proteins exhibit negative expression in the tumor tissue. The positive expression of P-gp and 10% of Ki-67 proteins is also observed. Conclusion This study successfully constructs a gemcitabine-resistant variant of the breast cancer cell line (4T1/Gem)and establishes a nude mouse model of breast cancer with hepatic metastatic, thereby providing an experimental basis for developing and treating a drug-resistant variant of breast cancer.

Objective To explore the application value of color Doppler ultrasound in patients with azoospermia who underwent testicular needle biopsy. Methods Retrospective analysed the clinical data of 53 cases patients with azoospermia from 2012 November to 2015 February in our department.All patients underwent routine scrotal ultrasonography, to detecte the peak systolic velocity (PSV), end diastolic velocity (EDV) and resistance index (RI) of testicular artery (TA)and intratesticular artery (ITA)with spectral Doppler ultrasound. Color Doppler ultrasound was used to observe the distribution and the number of blood vessels in the testicle, and semi quantitative score. All patients underwent testicular biopsy and Johnsen score. Results 47 patients were diagnosed as obstructive azoospermia(OA), 6 patients were diagnosed as non obstructive azoospermia(NOA). The average volume of testis was (15.3±3.6)mL in 0A group. The average volume of testis was (7.1±2.8) mL in N0A group.There was significant difference (P<0.01). The blood flow parameters(PSV, EDV, RI) results between OA group and NOA group have obvious difference,the difference was statistically significant (P<0.05). The semi quantitative classification of testicular vessels between OA group and NOA group have obvious difference,the difference was statistically significant (P< 0.01). Conclusion Color Doppler ultrasound is a good predictor of testicular spermatogenic function, can be used as the identification index of patients with OA and patients with NOA.
