80 male Wistar mice were randomly divided into 8 groups. The effects of the big black Ant preparations (alias Xuanju ) obtained in different ways and their compound preparations in different dosages on the amount of RNA and DNA in the testes of mice were observed. After administration of the preparations for 21 days, the mice were decapitated and the testes were excised and weighed. The RNA and DNA in the testes were isolated andpurified with the method of SDS- phenol and their amounts were measured with UV-VIS spectrophotometry. The results showed that the mean testes weight in the experimental groups was significantly higher than that in the control group (P

Magnetic resonance imaging (MRI), featuring as no ionizing radiation, higher soft tissue resolution and multiplanar imaging, has been widely used in the diagnosis of pediatric tumors. Conventional MRI techniques mainly provide information on morphological information of tumors but cannot display physiological and pathological changes in tumors. In recent years, with rapid development of MRI hardware and software, some functional MRI technologies have been applied in clinical practice and have become an important trend on pediatric oncology. These techniques include perfusion-weighted imaging, diffusion-weighted imaging, magnetic resonance spectroscopy, susceptibility weighted imaging. These new technologies can demonstrate the microstructural information of tumors, which will provide more helpful information for diagnosis, treatment and follow-up in pediatric tumors when combined with conventional MRI techniques.

Seventy C57BL/6 mice were divided into control group,lard group,lard transferred into safflower oil group,and safflower oil group.After 20 weeks,the white adipose tissues were taken to analyse the gene differentiational expression prolife.The results showed that body weight,blood glucose and lipids,and insulin levels in lard group were higher than those in control group( all P＜0.05 ),which were decreased after lard was transferred into safflower oil for 10 weeks( all P＜0.05 ).Safflower oil regulated some of the orexigenic genes,anorectic genes,and the genes involved in energy expenditure in adipose tissues such as opioid receptor,glucagon,and PPARα.

OBJECTIVE:To evaluate therapuetic efficacy and toxic reaction of 2 therapuetic regimens for 56 cases of bone me-tastasis of cervical cancer. METHODS:56 cases of bone metastasis of cervical cancer with complete information were collected ret-rospectively and randomly divided into radiochemotherapy group(31 cases)and diphosphonate group(25 cases). Radiochemothera-py group was given radiotherapy,chemotherapy and diphosphonate;diphosphonate group was given palliative symptomatic treat-ment of diphosphonate;a treatment course lasted for 3-4 weeks,and both groups received 3 courses of treatment. Average survival time,survival quality and toxic reaction were comparison in 2 groups. RESULTS:After bone metastasis of cervical cancer,the av-erage survival time of radiochemotherapy group was 17 months (95%CI:9.1-24.9),and that of diphosphonate group was 19 months (95%CI:2.4-35.6);3 years later,the survival rate of radiochemotherapy group was 16.1%,and that of diphosphonate group was 16.0%,there was no statistical significance(P=0.820). To compared KPS after 3 treatment courses,the improvement rate of radiochemotherapy group(22.6%)was significantly lower than that of diphosphonate group(40.0%),with statistical signif-icance (χ2=4.36,P<0.05). Toxic reaction of radiochemotherapy group was more significant than that of diphosphonate group. CONCLUSIONS:Diphosphonate has little effect on survial quality and slight toxic reaction. It is worthy of spreading in some pa-tients with advanced,elderly and reccurred bone metastasis of cervical cancer.

A SnO2-CuO composite nanofiber was prepared by the coaxial electrospinning method. A new thin-film-type hydrogen sulfide gas sensor was designed by coating SnO2-CuO composite nanofibers onto an alumina ceramic tube with Au electrodes by dip-coating method. The crystalline phase and microstructure of SnO2-CuO composite nanofibers were characterized using X-ray diffraction ( XRD ) and scanning electron microscope ( SEM) . The influence of chemical composition and thickness of sensitive film on the sensitive mechanism and electrochemical characteristic of SnO2-CuO nanofibers were analyzed. The characteristic tests of hydrogen sulfide sensor including sensitive performance, temperature, relative humidity, dynamic response, interference and stability were carried out by WS-30A type multifunction analyzer in gas sensor test system. The results demonstrated that, when the operating temperature was 25℃ and hydrogen sulfide gas concentration increased from 10 to 60 mg/L, the hydrogen sulfide sensor based on C50 composite nanofibers with 70 nm sensitive film thickness had the best linearity (92. 3%) and sensitivity (98. 2%). Besides, its highest response values and relatively humidity level were 1080 and 95%, respectively, and its dynamic response time and recover time were 4 s and 12 s, respectively. This sensor showed good anti-disturbance to the gases, such as CO, NO2 , SO2 , NH3 , CO2 , CH4 and H2 . The response value of the sensor was attenuated about 9. 2% when it was applied continually in the mine about 12 months, and its normal response time was 10. 9 months.

Objective To investigate the clinical value of anti-nuclear antibody(ANA) and anti-nuclear antibody spectrum(ANAs) detection.Methods A total of 2 325 patients with or suspected with autoimmune diseases(AID) were enrolled and detected for ANA and ANAs by using indirect immunofluorescence assay(IIF) and linear immunoblot assay(LIA) respectively.All detected results were analyzed.Results Among 2 325 patients,896 cases(38.54%) were positive with ANA,with positive rate of 45.46% in female patients,which was higher than the 18.46% of male patients(P<0.05),and the common fluorescence patterns were nuclear particle pattern,nuclear homogeneous pattern and the nucleolus pattern.816 cases(35.10%) were positive with ANAs,and the positive rates of anti-Sjogren's syndrome(SS)-B antibody,anti Ro-52 antibody and anti SS-A antibody were relatively higher.The consistency rate of the two methods was 91.66%.Conclusion ANA and ANAs detection could be with certain correlation,but might be not completely consistent,detection could improve the detection rate and reduce the missed detection rate.

Objective To study the feasibility and the efficacy of total extraperitoneal repair (TEP) under two laparoscopes.Methods Clinical data of 51 patients with inguinal hernia who underwent TEP under two laparoscopes from July 2015 to March 2016 in our hospital were analyzed retrospectively.During TEP,we added a 5-mm laparoscope for monitoring and exploration in the abdominal cavity.Results All the operations of TEP under two laparoscopes were successful.The operation time lasted 42-176 min with a mean of (74 ±27) min.The intraoperative blood loss was 5-30 ml with a mean of (12.8 ±5.9) ml.The length of postoperative hospital stay was 2-7 days with a mean of (4.0 ± 1.1) days.The percentage of postoperative complications was 11.8％ (6/51),including inguinal area seroma which accounted for 2.0％ (1/51),inguinal region pain accounting for 3.9％ (2/51),and postoperative urinary retention for 5.9％ (3/51).No infection was found.The follow-up period ranged from 3 to 11 months (mean,7 months),no recurrence was observed during this period.Conclusions TEP under two laparoscopes can treat inguinal hernia precisely.It is also helpful to find compound inguinal hernia and occult inguinal hernia.
