Objective To understand the mortality and potential life loss due to coronary heart disease (CHD) and stroke in Wujiang District, Suzhou from 2011 to 2022, and to provide strategies and basis for the prevention and treatment of CHD and stroke. Methods We collected the data of death cases due to CHD and stroke from the death monitoring system in Suzhou from 2011 to 2022. The mortality of CHD and stroke, potential years of life lost (potential years of life lost , PYLL), average years of life lost (average years of life lost , AYLL) and potential years of life lost rate (potential years of life lost rate , PYLLR) were calculated to analyze the development trend of death and disease burden of CHD and stroke. Results From 2011 to 2022, the crude mortality of CHD was 31.91/10 million, and that of stroke was 118.93/10 million. CHD and stroke mortality rates both showed an upward trend（P＜0.05, a statistically significant trend）. From 2011 to 2022, the mortality rate of CHD and stroke in Wujiang District increased rapidly with the increase of age. From 2011 to 2022, the disease burden caused by CHD totaled 11005 person-years, with PYLLR of 1.26% and AYLL of 12.34 years per person. The PYLL caused by stroke was 13 587.5 people-years, the PYLLR was 1.55%, and the AYLL was 8.93 years per person. PYLL, PYLLR and AYLL all decreased in women（P<0.05）, with no significant change in men（P>0.05）. Conclusion From 2011 to 2022, the mortality rate of CHD and stroke in Wujiang District appeared a tendency towards a rise, effective intervention and prevention measures should be taken among elderly and male residents.

In order to explore the role of pre-basic course teaching in the standardized training of residents in clinical pathology, we have independently designed and constructed a pre-basic course teaching system mainly focusing on anatomy and histoembryology, consisting of two levels of theoretical teaching (small lectures by students and systematic lectures by instructors) and two dimensions of practical training (sample collection teaching and case teaching). This teaching model centering on participatory lecturing, practice, summarization, assessment, and feedback has been demonstrated effective. The results showed that the theoretical and practical assessment scores of the experimental group [(458.80±17.60) and (415.40±19.30), respectively] were significantly higher than those of the control group [(444.50±20.90) and (398.80±23.70), respectively]. Among 28 students of grades 2019 to 2021 surveyed for teaching effectiveness, 96.43% were satisfied with the teaching model. The established teaching model provides new ideas for the reform of teaching methods in the standardized training of residents in clinical pathology.

Objective:To explore the value of conventional ultrasonography combined with cervical compression in the diagnosis of orbital venous malformation (OVM).Methods:A total of 43 patients with suspected OVM were admitted in sequentially from January 2019 to July 2022 in the Third Medical Center of PLA General Hospital. All patients were examined by ultrasonography combined with cervical compression and demonstrated by operation or digital subtraction angiography (DSA). The conventional ultrasound features of OVM were summarized, and the value of conventional ultrasonography combined with cervical compression in the diagnosis of OVM was discussed.Results:The features of the conventional ultrasound combined with cervical compression for diagnosis of OVM were as follows: the interior of lesion was mainly tubular structure, and the compression test was positive. After cervical compression, the lesion enlarged and the inner diameter of the internal tubular structure widened. Doppler flow imaging showed that the interior of lesion was mainly venous blood flow. Compared with the results of postoperative pathology or DSA, the sensitivity, specificity, accuracy and positive predictive value of ultrasonography combined with cervical compression were 0.952, 1.000, 95.3% and 100%, respectively. The results of Fisher exact diagnosis showed that there was no significant difference between ultrasonography and operation or DSA of OVM( P>0.05). Conclusions:Conventional ultrasound combined with cervical compression can be used as an effective method for the diagnosis of OVM.

Pathological specimen sampling is not only the prerequisite of a good pathological diagnosis, but also the primary clinical skill that must be mastered by the standardized residency training trainees (resident trainees) in clinical pathology department. In view of the problems and difficulties encountered in the teaching of specimen sampling, through five years of exploration and attempt, this paper has gradually established a new model with five basic elements, including theory teaching, practice teaching, promoting teaching effect by examination, learning from senior students, and review teaching. The results of evaluation analysis and questionnaire survey show that the teaching mode can make the trainees master the methods of specimen sampling quickly and efficiently, learn and improve clinical skills in practice, and lay a solid foundation for the subsequent standardized training of histopathological diagnosis.

Objective:To explore the value of 5G robotic remote ultrasound in the diagnosis of plateau pulmonary edema(HAPE).Methods:A total of 27 patients who quickly entered Nagqu, Tibet at an altitude of 4 600 m-5 600 m from March to December 2021 and developed one of the clinical symptoms of HAPE were collected. All patients were examined by 5G remote robotic ultrasound and lung CT respectively. Kappa test was used to analyze the consistency of the two diagnostic results, and McNemar test was used to compare the difference in diagnostic results. The ROC curve was used to analyze the sensitivity and specificity of remote lung ultrasound scores in the diagnosis of HAPE.Results:Among the 27 patients, 16 showed thickening of pleural line, increasing of B line, lung consolidation, pleural effusion, etc. Meanwhile, 11 showed no abnormality. Additionally, 8 cases had diffuse pulmonary fluid in both lungs, and 8 cases had localized pulmonary fluid. ROC curve showed that the area under the curve of lung ultrasound score for the diagnosis of HAPE was 0.947 (95% CI=0.78-0.99, P<0.001). The sensitivity and specificity were 0.933 and 0.917, respectively. Lung CT diagnosis was positive in 15 cases. Lung CT showed thickening of lung texture, ground glass, small nodular shadow, fine reticulate shadow, etc. The diagnostic results of the two techniques were in good agreement (Kappa=0.924, P<0.001), and there was no significant difference between the two methods ( P>0.05). Conclusions:5G remote robotic ultrasound has high consistency with CT in the diagnosis of HAPE and is an alternative early diagnosis method for HAPE. It may have clinical application value in scattered medical resources and remote plateau areas.

Transcranial direct current stimulation (tDCS) is a well-tolerated, safe and noninvasive physical brain stimulation method, which has been widely used in the treatment of some common mental disorders and neurological diseases and has achieved certain clinical effects. It is necessary to develop expert consensus on clinical treatment to improve the use norms in related fields. According to the clinical research published before August 2021 and the method of evidence-based medicine, we published an expert consensus on tDCS in the treatment of depressive disorders, schizophrenia, substance use-related disorders, obsessive-compulsive disorder, attention deficit hyperactivity disorder, autism, anxiety disorders, post-traumatic stress disorder, sleep disorders, pain, Parkinson′s disease, stroke, and epilepsy. The consensus also introduced the safety and efficacy of the clinical use of tDCS, and standardized the treatment process and operation technology, aiming to provide guidance for the clinical application of tDCS and promote the standardized development of this treatment technology in the future.
