Objective:To explore the feasibility of screening for major fetal heart disease by training sonographers in township or county level hospitals .Methods:Training of B ultrasound scan for congeni-tal heart defects was given to the sonographers from one county hospital , and thirteen township hospitals ( or the district hospitals ) , and training of fetal echocardiography was given to sonographers from four city/county hospitals.The trained sonographers who had passed the examinations and had obtained quali-fications after six months of independent practice began to screen fetal congenital heart defects .To evalu-ate the effectiveness , sensitivity and specificity of screening was calculated by using the diagnosis of ex-pert neonatal/fetal echocardiographers as the gold standard .Results: A total of 3 425 fetuses received one fetal B ultrasound screening , one fetal echocardiography and one neonatal echocardiography from April 1, 2004 to December 31, 2005.One hundred and sixty-five B ultrasound screening images (4.9%) from township hospitals and fifty-six fetal echocardiography images (1.7%) from county or city centers couldn ’ t be reviewed because of poor quality .The sensitivity of fetal B ultrasound screening in the township and county hospitals was 30%and 0, and the specificity 93.3%and 99.9%, respectively. Nine fetuses with a major congenital heart disease were eventually found by the trained sonographers , and two cases were misdiagnosed and two unnoticed .The total sensitivity and specificity of fetal echocardio-graphy were 81.8% and 99.9%, respectively.The sensitivity in the county and city hospitals was 66 .7% and 100%, respectively .The specificity in the county and city hospitals was 99 .9%and 100%, respectively .Conclusion: Under the current circumstances , township hospitals are unable to perform effective fetal cardiac screening .Screening on fetal congenital heart disease is suggested to be taken by trained sonographers in county and city level medical centers .

Objective　To study the relationship between bax gene expression and endometrial carcinoma. Methods　Bax mRNA expression was evaluated by RT-PCR in a series of 8 normal proliferative endometrium (NPE), 6 simple and complex hyperplasia (SCH), 6 atypical hyperplasia (AH) and 42 endometrial carcinoma (EC).Results　All of the 8 NPE showed moderate bax mRNA expression. In 1 of 6 SCH, 2 of 6 AH and 27 of the 42 EC (64.3%), there was overexpresion of bax mRNA. In endometrial carcinoma, with the progression of clinical stage, increase in histologic grade and in depth of invasion to muscle layer, and lymph node metastersis,the positive rate of bax overexpression was correspondingly increased.Conclusion　The results suggest that bax expression affects the balance between the endometrial cell proliferation and apoptosis. Bax might play an important role in carcinogenesis and tumor progression of endometrial carcinoma. As a high risk factor it can be used to evaluate the biological behavior of endometrial carcinoma.

Objective: To investigate the mechanism of electroacupuncture (EA) for treating depression and to explore the role of brevican in the medial prefrontal cortex (mPFC) in modulating stress susceptibility and the antidepressant effects of EA in rats. Methods: Twenty-four Sprague–Dawley (SD) rats were equally divided into three groups: green fluorescent protein (GFP) + control, GFP + chronic unpredicted mild stress (CUMS), and short-hairpin RNA targeting on brevican (shBcan) + CUMS. Another 24 SD rats were equally divided into CUMS + GFP, CUMS + GFP + EA, and CUMS + shBcan + EA groups. Behavioral tests were conducted to assess depression-like behavior. Western blot analysis was used to evaluate the expression of brevican, aggrecan, GLuA1, and PSD95 in mPFC subregions. Results: Behavioral parameter evaluation show that rats in the shBcan + CUMS group exhibited a significantly reduced sucrose preference (P = .0002) and increased immobility time (P = .0011) compared to those in rats in the GFP + CUMS group. Western blotting showed that brevican expression was significantly downregulated in the PrL of the shBcan + CUMS group compared with that in the GFP + CUMS group (P = .0192). Furthermore, compared to the CUMS + GFP + EA group, the CUMS + shBcan + EA group exhibited a significantly decreased sucrose preference (P = .0334), increased immobility time (P = .0465), and increased latency to food (P = .0261). In the CUMS + shBcan + EA group, the EA-induced brevican and PSD95 overexpression was reversed, compared with that in the CUMS + GFP + EA group (P = .0454 and P = .0198, respectively). Conclusion EA exerts its antidepressant effects through the modulation of brevican expression in rats. Our findings highlight the important role for brevican in stress susceptibility, which could be a potential target for treating depression.

Objective:To summarize the perioperative nursing points of percutaneous kyphoplasty (PKP) in elderly patients with osteoporotic vertebral compression fractures assisted by robots, so as to provide reference for orthopedic nursing.Methods:From July 2019 to February 2021, the data of 72 patients undergoing robot-assisted PKP in the spinal surgery of the First Affiliated Hospital of Anhui Medical University were retrospectively analyzed. The perioperative nursing points were summarized, and the nursing experience was summarized. The nursing under the new measures of precise minimally invasive treatment was analyzed and discussed. The length of hospital stay, postoperative ambulation time, complications and satisfaction survey results of patients were collected and recorded. The Numerical Rating Scale(NRS) score, Self-rating Anxiety Scale(SAS) score and Oswestry Disability Index (ODI) score before and after surgery were compared. The correlation analysis of the scores of various factors was combined to comprehensively evaluate the surgical and nursing effects.Results:All patients had no complications related to machine use during and after operation, and their symptoms were improved to varying degrees. Fifty-seven cases of indwelling catheter, catheter time (19.00±14.24) h. The preoperative hospitalization time was (6.16±2.22) d, and the postoperative hospitalization time was (1.94±0.99) d. Postoperative bed time was (16.34±6.81) h. Postoperative nursing satisfaction was (98.55±2.44)%.The postoperative NRS and SAS scores were (1.00±0.55) and (32.06±5.33) points, respectively, which were lower than those before operation (3.51 ± 0.71) and (39.08±8.86) points, and the differences were statistically significant ( t values were 33.976, 8.184, P<0.01). There were statistically significant differences in six indicators of ODI scores before and after surgery, including low back pain, walking, standing, sitting, sleep and self-care ( P<0.01). Correlation analysis showed that there was a strong correlation between the six ODI score factors and the NRS score. The four factors of sitting, walking, low back pain and standing were highly correlated with SAS. Conclusions:The implementation of good perioperative nursing management for patients with PKP assisted by robot can effectively promote the rehabilitation of patients, reduce the incidence of complications and improve patient satisfaction.
