EXPERIMENTAL SPINAL CORD TRAUMATIC INJURY OF THE CAT TREATED WITH ELECTRO-ACUPUNCTURE

44 cats were used in this experiment. The spinal cords of 40 animals were injuredat about L_1 level by using Allen's method (400g/cm) and randomly divided into 2 groups: A)electro-acupuncture treatment group (n=20) and B) control group(n=20). 2 weeks after spinalcord injury, 80% of animals in the treatment group were survival and 45% of animals in the con-trol group were survival. There was significant difference between these two groups (p<0. 05).The motor evoked potential was recorded two weeks after spinal cord injury. The latency of theshort latency peak was 15. 61±4. 98 mS and the amplitude was 10. 61 0. 59 mV in the treatmentgroup; and 21. 7±5. 02 mS and 0. 56±0. 32 mV in the control group. Both latency and amplitudewere significant different between the two groups (P<0. 05, P<0. 05). The Anti-NF-H (neuro-filament) was determined at 2 and 4 weeks respectively after spinal cord injury. The more NF-Hpositive labeling fibers were found in the treatment group than in the control group (P<0. 01 ).The

Ovarian hyperstimulation syndrome: a clinical retrospective study on 565 inpatients

Abstract

The aim of this study was to analyze clinical manifestations of 565 ovarian hyperstimulation syndrome (OHSS) inpatients in the largest Obstetrics and Gynecology hospital in China from year 2010 to 2017, to get more understanding of epidemiologic features of this disease, and to provide some insight on the diagnosis, treatment, and preventions of OHSS. It is a clinical retrospective study. In the 565 cases that developed OHSS over an eight-year period between 2010 and 2017 were reviewed, we assessed patients’ general characteristics, clinical manifestations, treatment, prognosis, and the relationship between different indicators and the severity of OHSS. Totally 12 kinds of ovulation induction protocols (Protocol 1: CC; Protocol 2: Gn; Protocol 3: hCG; Protocol 4: GnRh-a; Protocol 5: CC & Gn; Protocol 6: CC & hCG; Protocol 7: Gn & hCG; Protocol 8: GnRh-a & Gn; Protocol 9: CC & Gn & hCG; Protocol 10: GnRh-a & CC & Gn; Protocol 11: Letrozole & Gn & hCG; Protocol 12:GnRh-a & Letrozole & Gn) were analyzed and the Odds Ratio (OR) of each protocol were calculated. Five hundred and sixty-five patients were reviewed in our study. In all these patients, the number of hospitalizations, mean age, primary infertility rate, and pregnancy rate did not differ through the last 8?years. From which we may infer that the incidence rate of OHSS may not change over the last 8?years. Older patients tend to develop into more severe stage easily. The pregnancy rate was much lower in mild stage patients, but no difference was found between patients in moderate, severe and critical stage. Oocytes retrieval is strongly associated with severity. PCOS history, irregular menstrual cycle and infertility type do not seem to affect the severity of OHSS. Twelve kinds of ovulation induction protocols were analyzed, OR of different protocols were calculated, what is noteworthy is that patients who used GnRh easily developed more severe OHSS than the patients who received oocytes retrieval. We suggest that we may choose ovulation induction protocols according to the OR table while treating women with high-risk factors.

Research on Dynamic Compressive Performance and Failure Mechanism Analysis of Concrete after High Temperature and Rapid Cooling

To investigate the dynamic compressive properties of concrete after high temperature and rapid cooling, an experimental study was carried out by considering five temperatures and four strain rates. The coupling effect of high temperature and strain rate on concrete damage morphology and mechanical parameters was comparatively analyzed. The main conclusions are as follows: the compressive damage morphology of concrete is affected by strain rate development trends of significant variability under different temperature conditions. As the strain rate increases, the compressive stress and elastic modulus of concrete are gradually increased. As the temperature increases, the increase in compressive stress is gradually reduced by the strain rate. For the temperatures of 20 °C and 800 °C, the increase in compressive stress by the strain rate is 38.69% and 7.78%, respectively. Meanwhile, SEM and CT scanning technology were applied to examine the mechanism of the effect of high temperature and strain rate on the mechanical properties of concrete from the microscopic perspective, and the corresponding constitutive model was proposed.
