We have engaged in active exploration on how to improve teaching effectiveness of Ideological and Moral Cultivation and Legal Basis.We used many methods,such as changing teaching concepts,studying teaching content,reforming teaching and test methods etc.and have achieved a certain degree of success.

Objective To explore the feasibility and efficacy of laparoscopic rectopexy with peritoneal strips for severe complete rectal prolapse (SCRP) in children. Methods From August 2004 to October 2008,6 patients (aged 2 to 6 years with a mean of 3.5) with SCRP were treated in our hospital. The clinical data of the patients were reviewed. Under the laparoscope,two L-shaped peritoneal strips with the pedicle were cut from the incrassated and slack peritoneum of the pelvic cavity on bilateral sites of the rectum,and then were folded and sutured with the lateral wall of the free rectum with the ends being stitched on the fascia in front of the sacral promontory to suspend the rectum. Afterwards,the incisal margin of the peritoneum was sutured together with the anterior wall of the rectum in order to embed the peritoneal strips and reconstruct the pelvic peritoneum. Results All of the 6 cases of laparoscopy were completed successfully with a mean operation time of (120?24) min (ranged from 95 to 210 min). The blood loss was less than 10 ml in all of the cases. The patients received a mean of 28-month follow-up (range,6 to 54 months),during the period,none of them had recurrence or abnormal bowel movement. Conclusions Laparoscopic rectopexy with peritoneal strips is an effective and satisfactory treatment for SCRP with minimal invasion,quick recovery and a low-recurrence rate.

Objective To evaluate the effectiveness of laparoscopic sutured anastomosis of the duodenum for children with congenital duodenal obstruction (CDO). Methods From February 2003 to July 2008,13 patients (aged 2 days to 12 years) with CDO underwent laparoscopic sutured anastomosis of the duodenum in our hospital. Among the cases,7 were newborns,3 were infants,and 3 were children. Laparoscopy showed duodenal atresia or stenosis in 7 cases,annular pancreas in 2 cases,superior mesenteric artery syndrome (SMAS) in 3 cases,and preduodenal portal vein in 1 case. Results Excepting the patient with preduodenal portal vein,who was converted to mini-laparotomy for duodenojejunostomy,all the cases were treated by laparoscopy. In 5 cases,the diaphragm was excised partially after a vertical incision was made at the anterior part of the duodenum,and then a transverse suture was completed; the 2 patients with duodenal atresia and the 2 with annular pancreas received diamond-shaped side-to-side duodenoduodenal anastomosis under a laparoscope; and the 3 cases of SMAS were treated by Roux-en-Y duodenojejunostomy. The mean operation time in this series was (97.0?18.2) min (range,75 to 180 min). No intraoperative complications occurred. The patients started oral intake in 2 to 5 days after the surgery,and resume a normal diet in 7 to 9 days. Before being discharged from the hospital,upper gastrointestinal tract imaging showed no evidence of obstruction in the patients.A follow-up up to 6 months to 4 years were available in 11 patients,among which 8 were followed for more than 1 year. During the period,the patient developed well. Conclusions The laparoscopic sutured anastomosis of the duodenum is feasible and effective for children. It can be performed in neonates securely as an excellent minimally invasive treatment for congenital duodenal obstruction.

In action-oriented teaching,"the action learning" principle was adhered to as far as possible so that learners could learn through action.The author in the ideological and political theory teaching took a series of teaching methods based on philosophy of "action-oriented teaching" and received remarkable results.

The quality of teachers is the key to enhance the effectiveness of "Two Courses" teaching.This paper mainly talks about the basic qualities of "Two Courses"teachers,such as the ideology and politics,professional ethics,theory,business technology,capacity and so on.

Objective To observe the time course of the changes in nitric oxide (NO) content and the activity of NO synthase (NOS) during hippocampal long term potentiation (LTP) in vitro . Methods The production and maintenance of LTP were detected by using extracelluar electrophysiological recording. NO content and NOS activity were determined by biochemical reaction. The expression of NOS mRNA was detected by in situ hybridization. Results Conditioning stimulation for 10 min induced LTP production and significant increases in NO content, NOS activity and expression of NOS mRNA. However, at 60 min after conditioning stimulation, LTP remained stably but NO content and NOS activity returned to the pre conditioning stimulation level. Moreover, the NOS mRNA was overexpressed at the early stage of LTP production. Conclusion Significant NO changes may occur at the early stage of LTP formation.

Objective To evaluate the relationship of the plasma levels of osteopontin(OPN),lipoprotein (a) [Lp (a)] and apolipoproteinA/apolipoproteinB (ApoB/ApoA1) ratio with atherosclerosis.Methods 120 elderly patients with atherosclerosis (observation group) and another 120 healthy elderly subjects (control group) from Health Check Department in Tianjin Third Center Hospital were enrolled from Mar.2014 to Nov.2015.The levels of plasma OPN,Lp(a) and ApoB / ApoA1 ratio were measured and their relationship with atherosclerosis was analyzed.Results In observation group versus control group,the levels of plasma OPN[(33.2±10.1) μg/L vs.(30.6± 9.1) μg/L],ApoB/ApoA1 ratio[(0.8±0.7) vs.(0.6±0.1)]and Lp(a)[(357.6±66.5) mg/L vs.(120.5±35.7) mg/L] were increased with statistically significant differences (t =8.91,8.43,6.01;P=0.021,0.035,0.041).The concentrations of plasma OPN,ApoB/ApoA1 ratio and Lp (a) were increased along with aggravation of artery lesion,with statistically significant differences (F =8.50,7.38,6.41;P=0.031,0.039,0.037).Conclusions The plasma levels of OPN,Lp(a) and ApoB/ ApoA1 ratio are increased in patients with atherosclerosis and increased along with the lesion aggravation.

Objective To explore the effects of diethylenetriamine/nitric oxide (DETA/NO)on capillary spasm and early brain injury (EBI)after subarachnoid hemorrhage (SAH)in rats.Methods Sixty-nine male Sprague-dawley rats were randomized into three groups:sham group,SAH group and DETA/NO group.SAH model was established by wearing out the willis ring with thread and then Garcia neurological score was observed in the general animals.The expressions of alpha smooth muscle actin (αSMA)and PDGFRβwere detected by dual immunofluorescence staining;nitric oxide kit was used for detecting brain tissue NO concentration.Changes in the hemoglobin-stimulated capillaries were observed in rat slices.Results Three days after surgery,neurological deficit score was remarkably improved in DETA/NO group compared with that in SAH group (P<0 .0 5 ). Immunofluorescence results showed that the expressions of peri-capillaryαSMA and PDGFRβwere significantly increased after SAH (P<0.05 ),and that DETA/NO could down-regulate the expressions (P<0.05 ).NO concentration was greatly reduced about 3 hours after SAH and then gradually increased;DETA/NO could maintain the concentration of NO at an early stage (P<0 .0 5 ).The capillary contraction was observed in slices perfused with hemoglobin;DETA/NO could alleviate capillary spasm.Conclusion DETA/NO can alleviate the severity of capillary spasm and EBI after SAH in rats.

To compare the clinical efficacy of calcium sodium edetate （EDTA） and the low-dose sodium dimercaptopropanesulfonate（DMPS） in treating cerebral Wilson’s disease. Methods Eighty patients with neurological Wilson’s disease in the neurology department of the first affiliated hospital of Anhui traditional Chinese medicine from February 2019 to September 2021 were collected and divided into the EDTA treatment group（n=39） and the low-dose DMPS control group（n=41）based on treatments. Propensity score matching （PSM） was performed on the two groups of patients and the results were compared after matching. The copper displacement effects of the two groups were compared，and the deterioration of copper displacement and adverse reactions were observed. Results After PSM，35 patients in EDTA group and 35 patients in the low-dose DMPS group were included. UWDRS Ⅰ in EDTA group showed significant statistical difference after treatment［（57.03±21.06） versus （54.40±20.02），t=7.256，P<0.001］，while UWDRS Ⅰ in the low-dose DMPS group showed no significant statistical difference［（53.49±26.82） versus （52.37±27.17），t=1.544，P=0.129］. Compared with the low-dose DMPS group，there was no significant difference in 24-hour urinary copper detection in the EDTA group［551.18 （417.77，843.47） versus 489.20 （389.64，839.47），Z=0.029，P>0.05］. The neurological deterioration （P=0.025） and adverse reactions were significantly reduced. Conclusion EDTA and low-dose DMPS have the same effect in expelling copper in patients with neurological WD，with better improvement，less neurological deterioration probability，and fewer adverse reactions. EDTA can be used as a copper removing treatment for patients with neurological WD.
