The implementation of ideological and political education in medical colleges and universities should be combined with the talent cultivation goals of medical education,in line with the internal needs of medical career development and scientific research ethics construction,and enhance the pertinence and effectiveness of education.Medical students in the new era should be rich in"benevolence"and have firm political beliefs in their ideology,be full of"benevolent skills"and abide by professional ethics and morality.Therefore,it's an important measure for medical colleges and universities to carry out the innovations of ideological and political education in the integration of political beliefs and professional ethics that are guided by political beliefs and based on professional ethics.To enhance the effect of"integration",comprehensive policies need to be implemented from the aspects of educational content,educational field,educational form,and educational team,to achieve the"organic integration"and"mutual penetration"of political belief education and professional ethics education,as well as create a new model of ideological and political education in medical colleges and universities.

The great anti-epidemic spirit formed in the practice of fighting against the COVID-19 epidemic is a vivid embodiment of the national spirit and zeitgeist, an important part of the spiritual spectrum of the Communist Party of China, and an important content of professional ethics education for medical students in the new era. In the context of the new era, it is of great significance to integrate the great anti-epidemic spirit into the professional ethics education of medical students and explore its theoretical basis and existing problems. Based on the empirical investigation, this paper proposed the practical path of integrating the great anti-epidemic spirit into medical students’ professional ethics education from three dimensions:subject’s cognitive consciousness, school education practice, and hospital clinical training, to effectively exert the nurturing function of the great anti-epidemic spirit and improve the timeliness of professional ethics education for medical students.

Objective:To investigate the efficiency of biochemical screening and hotspot gene screening in the detection of neonatal inherited metabolic diseases.Methods:This was a prospective multi-center study.The study was carried out on 21 442 neonatal samples collected from 12 hospitals in 10 provinces from November 2020 to November 2021.The results of biochemical screening and hotspot gene screening were analyzed jointly.Biochemical screening methods included glucose-6-phosphate dehydrogenase deficiency enzyme activity assay and neonatal tandem mass spectrometry.Genetic screening analysis involved 135 genes associated with 75 neonatal diseases.Results:Of all the 21 442 neonates enrolled in the study, 21 205 were subject to biochemical screening.A total of 813 cases were positive in the initial screening, and 0.45% of them (95 cases) were diagnosed after recall.All the 21 442 neonates underwent gene screening.About 168 positive cases were detected in the initial screening, and 0.73% (156 cases) of them were confirmed finally.Biochemical and genetic screening improved the detection sensitivity of such diseases as primary carnitine deficiency, neonatal intrahepatic cholestasis caused by citrin deficiency, and 2-methylbutyrylglycinemia.Moreover, biochemical and genetic screening enabled the detection of more diseases, including the common single-gene genetic diseases such as thalassemia and Wilson disease.Conclusions:In neonatal screening, the combination of biochemical screening and gene screening expands the number of diseases detected and improve screening efficiency.

The prevalence of diabetes in China is increasing year by year， and has become a health issue of close concern to the whole society. Glucagon-like peptide-1 （GLP-1） receptor agonist （GLP-1RA）， as a new class of glucose-lowering drugs， is now widely used in the treatment of type 2 diabetes mellitus （T2DM） because of its significant glucose-lowering efficacy and low risk of hypoglycemia. As the level of evidence for its effects on improving cardiovascular system and renal protection and reducing body mass continues to improve， its status in the treatment guidelines for T2DM is gradually increasing. Currently， nine GLP-1RA drugs have been approved for the clinical treatment of T2DM in China. Although all of these drugs exert hypoglycemic effects based on the activation of GLP-1 receptors in the body， the differences in their own structures and natural GLP-1 amino acid homology lead to large differences in pharmacokinetic parameters and clinical efficacy among different analogs. In order to enable clinicians and pharmacists to have a full understanding of the characteristics and clinical evidence of these analogs and to better perform their therapeutic effects， Liaoning Provincial Pharmaceutical Society organized clinical medicine and pharmacy experts to develop a medication guide for nine GLP-1RA drugs to provide a reference for clinical medication needs and promote rational and standardized use by compiling and summarizing the pharmacological characteristics， clinical applications， adverse reactions， interactions， the medications in special populations and medication management.

Objective: To determine the spatiotemporal distribution of Schistosoma (S.) japonicum infections in humans, livestock, and Oncomelania (O.) hupensis across the endemic foci of China. Methods: Based on multi-stage continuous downscaling of sentinel monitoring, county-based schistosomiasis surveillance data were captured from the national schistosomiasis surveillance sites of China from 2005 to 2019. The data included S. japonicum infections in humans, livestock, and O. hupensis. The spatiotemporal trends for schistosomiasis were detected using a Joinpoint regression model, with a standard deviational ellipse (SDE) tool, which determined the central tendency and dispersion in the spatial distribution of schistosomiasis. Further, more spatiotemporal clusters of S. japonicum infections in humans, livestock, and O. hupensis were evaluated by the Poisson model. Results: The prevalence of S. japonicum human infections decreased from 2.06% to zero based on data of the national schistosomiasis surveillance sites of China from 2005 to 2019, with a reduction from 9.42% to zero for the prevalence of S. japonicum infections in livestock, and from 0.26% to zero for the prevalence of S. japonicum infections in O. hupensis. Analysis using an SDE tool showed that schistosomiasis-affected regions were reduced yearly from 2005 to 2014 in the endemic provinces of Hunan, Hubei, Jiangxi, and Anhui, as well as in the Poyang and Dongting Lake regions. Poisson model revealed 11 clusters of S. japonicum human infections, six clusters of S. japonicum infections in livestock, and nine clusters of S. japonicum infections in O. hupensis. The clusters of human infection were highly consistent with clusters of S. japonicum infections in livestock and O. hupensis. They were in the 5 provinces of Hunan, Hubei, Jiangxi, Anhui, and Jiangsu, as well as along the middle and lower reaches of the Yangtze River. Humans, livestock, and O. hupensis infections with S. japonicum were mainly concentrated in the north of the Hunan Province, south of the Hubei Province, north of the Jiangxi Province, and southwestern portion of Anhui Province. In the 2 mountainous provinces of Sichuan and Yunnan, human, livestock, and O. hupensis infections with S. japonicum were mainly concentrated in the northwestern portion of the Yunnan Province, the Daliangshan area in the south of Sichuan Province, and the hilly regions in the middle of Sichuan Province. Conclusions: A remarkable decline in the disease prevalence of S. japonicum infection was observed in endemic schistosomiasis in China between 2005 and 2019. However, there remains a long-term risk of transmission in local areas, with the highest-risk areas primarily in Poyang Lake and Dongting Lake regions, requiring to focus on vigilance against the rebound of the epidemic. Development of high-sensitivity detection methods and integrating the transmission links such as human and livestock infection, wild animal infection, and O. hupensis into the surveillance-response system will ensure the elimination of schistosomiasis in China by 2030.

Blast injury of the chest injury is the most common wound in modern war trauma and terrorist attacks, and is also the most fatal type of whole body explosion injury. Most patients with severe blast injury of the chest die in the early stage before hospitalization or during transportation, so first aid is critically important. At present, there exist widespread problems such as non-standard treatment and large difference in curative effect, while there lacks clinical treatment standards for blast injury of the chest. According to the principles of scientificity, practicality and advancement, the Trauma Society of Chinese Medical Association has formulated the guidance of classification, pre-hospital first aid, in-hospital treatment and major injury management strategies for blast injury of the chest, aiming to provide reference for clinical diagnosis and treatment.

Objective:To explore the diagnostic value of motion pain induction test for early knee osteoarthritis.Methods:A cross-sectional study was conducted and the data came from The Project of Health Management of Knee osteoarthritis in Community in Hangzhou in 2018, and a total number of 1 816 people were included which were divided into normal group ( n=530), early group ( n=534) and middle-late group ( n=752) by not sick, sick while Kellgren-Lawrence (KL) ≤Ⅱ and sick while KL>Ⅱ starting, squatting, walking up and down stairs and doing housework were included in the test, and the statistical indicators included age, gender and pain scores (visual analogue scale, VAS). Receiver operating characteristic (ROC) curves were mapped after the correlation analysis to obtain the cut-off points and compare their values of area under the curve (AUC). The confounders which included age and gender were corrected by propensity score matching (PSM) and the balance test is consistent with P>0.05 after the PSM. The Kappa analysis was used to verify the consistency of two diagnostic methods. Results:The age of normal, early and medial-late groupwas 67.39±7.43, 67.41±9.52, 71.55±9.87. And the gender distribution of three groups was (238 male, 292 female), (209 male, 325 female), (357 male, 395 female). There was no heterogeneitybetween the normal group and early group in distribution ( P>0.05) while there was heterogeneity between the early and medial-late group ( t=-0.034, P<0.05; χ2=8.80, P<0.05). The VAS scoresof starting pain in three groups was 0.16±0.37,2.70±1.69, 3.68±2.10. The VAS scoresof squatting pain was 0.42±0.49, 2.88±1.44, 4.01±2.08. The VAS scoresof up and down stair pain was 0.47±0.50, 2.87±1.38, 3.82±1.98. The VAS scoresof housework pain was 0.14±0.35, 2.15±1.40, 3.45±2.09. The VAS scoresofmaximum pain was 0.51±0.50, 3.59±1.48, 4.68±2.01. And there was significant difference between normal and early groupin all kinds of pain ( t=-33.81; t=-37.25; t=-37.66; t=-32.07; t=-45.41; P<0.05). The difference between early and medial-late group in all type of pain was significant ( t=-8.93; t=-10.84; t=-9.56; t=-12.52; t=-10.64; P<0.05). The results were similar after adjusting for confounders except for the pain of starting ( P>0.05). The results of ROC curve between normal and early group showed the maximum pain's AUC point was 0.98 and larger than others, and its cut-off point was 1. After adjusted, the results of ROC curve between early and medial-late group showed the maximum pain's AUC point was 0.72 which was larger than others and cut-off point was 4. For the AUC of ROC curve between early and medial-late groupwas lower, Kappa-test was used, and the Kappa point of two diagnostic methods was 0.41 ( P<0.05). Conclusion:The maximum of pain score in pain dimension>1 and ≤ 4 could be preliminarily diagnosed as early KOA. It had high value in separating early KOA from normal people and approximately similar to X-ray, and the value of identifying early and mid-late KOAwas moderateas well as the moderate consistency with KL stage. Comprehensive judgment of imaging examination should be improved when conditions are available.

Objective To analyze the clinicopathological features and prognosis of patients in endometrial cancer with bone metastases. Methods A retrospective review of medical records was performed to analyze patients with endometrial cancer who developed bone metastases at Peking Union Medical College Hospital (PUMCH) from January 2004 to December 2017, including patients with bone metastases at the diagnosis of endometrial cancer and at recurrence of endometrial cancer. The patient′s clinicopathological features, bone metastasis characteristics, treatment process and prognoses were also analyzed. Results The incidence of bone metastasis of endometrial cancer in PUMCH from 2004 to 2017 was 0.57% (14/2 458). (1) General clinical pathological features: the median age of the 7 patients with bone metastases diagnosed at the time of initial diagnosis was 50 years old, and the main pathological type was endometrioid carcinoma (n=5). The median age of the other 7 patients was 57 years old, with no significant difference comparing to the former groups (P=0.559). (2) The majority site of bone metastasis in endometrial cancer were discovered in pelvic bones, followed by the tibia. (3) Treatment: according to the staging of endometrial cancer, a comprehensive treatment based on surgery was performed, and one patient with isolated bone metastases underwent resection of bone metastasis. (4) Prognosis: nine out of the 14 patients died during the follow-up period. The median over all survival time was 25.5 months (range: 7.7-258.0 months). The median survival of population after diagnosis of bone metastases was 15.0 months (range: 3.0-51.0 months). The survival rate of endometrial cancer at 1-year after diagnosis of bone metastasis was 71.4%. The 2-year survival rate was 40.8%. (5) No independent prognostic factors affecting survival was found (P>0.05). Conclusions The incidence of bone metastasis in endometrial cancer is less than 1%. Bone metastasis could occur at the diagnosis of endometrial cancer or recurrence of endometrial cancer. Bone metastasis suggests a poor prognosis. There is no standard follow-up and treatment protocols so that individualized treatment is needed.

Objective To evaluate the defecation function of patients with low rectal cancer after laparoscopic-assisted transanal total mesorectal excision (TaTME),and analyze the influencing factors.Methods The retrospective case-control study was conducted.The clinicopathological data of 55 patients with low rectal cancer who underwent laparoscopic-assisted TaTME in the First Hospital of Jilin University from May 2017 to December 2018 were collected.There were 39 males and 16 females,aged (60-± 11) years,with a range from 24 to 80 years.Among the 55 patients,21 were in TNM stage Ⅰ,14 were in TNM stage Ⅱ,and 20 were in TNM stage Ⅲ;24 were in pathological stage T1-2 and 31 were in pathological stage T3.Observation indicators:(1) surgical and postoperative conditions;(2) follow-up;(3) analysis of influencing factors for postoperative defecation function.Follow-up was performed using questionnaires by telephone interview to detect the complications at 3 and 6 months after surgery up to June 2019.The measurement data with normal distribution were expressed as Mean± SD,and comparison between groups was done using the t test.Count data were expressed as absolute numbers or percentages,and comparison between groups was analyzed using the chi-square test or Fisher exact probability.Univariate and multivariate analyses were performed using logistic regression models.Results (1) Surgical and postoperative conditions:55 patients successfully underwent laparoscopic-assisted TaTME without conversion to open surgery.The operation time,volume of intraoperative blood loss,diameter of postoperative pathological specimen,time to urinary catheter removal,distance between the anastomostic stoma and anal verge,and tumor diameter were (246±62) minutes,(69±27) mL,(3.5±0.7) cm,(2.1±0.9) days,(2.4±0.5) cm,and (3.9-± 1.6)cm,respectively.(2) Follow-up:55 patients were followed up at 3 months and 6 months after surgery,and the low anterior resection syndrome questionnaires were completed.Among the 55 patients,35 had low anterior resection syndrome at 3 months after surgery,and 24 had low anterior resection syndrome at 6 months after surgery,showing a significant difference (x2 =4.42,P＜0.05).There was no new onset low anterior resection syndrome in 55 patients after 3 months.(3) Analysis of influencing factors for defecation function:univariate analysis showed that the distance between the anastomotic stoma and anal verge and tumor diameter were influencing factors affecting defecation function of patients at 3 months after surgery (x2 =19.075,8.185,P＜ 0.05).The distance between the anastomotic stoma and anal verge was a influencing factor affecting the defecation function of patients at 6 months after surgery (x2=9.183,P＜0.05).Multivariate analysis showed that the distance between the anastomotic stoma and anal verge ＜ 2 cm,and tumor diameter ＞5 cm were independent risk factors affecting the defecation function of patients at 3 months after surgery (odds ratio =1.135,6.057,95％ confidence interval:1.089-1.323,1.206-30.435,P＜0.05).The distance between the anastomotic stoma and anal verge ＜ 2 cm was an independent risk factor affecting the defecation function of patients at 6 months after surgery (odds ratio =2.724,95％ confidence interval:1.982-3.066,P＜0.05).Conclusions The incidence of low anterior resection syndrome after laparoscopic-assisted TaTME for low rectal cancer is high.Distance between the anastomotic stoma and anal verge and tumor diameter are independent risk factors for the postoperative defecation founction.

Objective To study the clinical outcomes of robotic extended thymectomy and thoracoscopic extended thymectomy for thymoma patients with myasthenia gravis compared with conventional median sternotomy extended thymectomy.Methods The clinical data of thymoma patients with myasthenia gravis treated by extended thymectomy between June 2013 and June 2016 were retrospectively reviewed.The clinical outcome parameters were compared according to surgical approach.Results 41 thymoma patients with myasthenia gravis,8 cases underwent robotic extended thymecotmy,11 cases underwent thoracoscopic extended thymectomy and 20 underwent median sternotomy extended thymectomy.The resected extension included tumor,thymus tissue and adipose tissue in anterior mediastinum.There were no significant differences between robotic group and thoracoscopic group regarding operative time,blood loss,chest tube duration,hospital stay,postoperative complications and postoperative myasthenic crisis (P ＞ 0.05).The blood loss of robotic group and thoracoscopic group was significantly lower than that in median sternotomy group(P ＜ 0.05).The chest tube duration of thoracoscopic group was significantly shorter than that in median sternotomy group(P ＜0.05).The effective rates of MG after extended thymectomy in robotic group,thoracoscopic group and sternotomy group was 65.0％ 、69.2％ 、62.5％ respectively and there was no significant difference (P ＜ 0.05).Conclusion Robotic thymectomy and thoracoscopic thymecotomy are both minimal invasive surgery approach with less bleeding for thymoma patients with myasthenia gravis.The clinical outcomes of robotic thymectomy and thoracoscopic thymecotomy are similar.
