In order to improve the professional level and service ability of general practitioners, this study is guided by the needs of community medical institutions in the county medical communities. Two small-class training of 15 modules were carried out for a week, taking "2+5" training mode, including 2 days of theoretical teaching and case discussion, and 5 days of bedside teaching. After the training, the theoretical examination, case report and objective clinical structured examination were carried out. Those who passed the examination were issued a certificate of qualification and given corresponding rewards. The results showed that the post-test scores of trainees after training were significantly improved compared with the pre-test scores, and the qualification rate increased from 18.4% to 85.9%. This training mode can be promoted in a wider range, but it should be adjusted appropriately according to the actual situation in various places, and the relevant departments and hospitals should give full support.

Objective:To explore the risk factors of subsyndromal delirium (SSD) after cardiac surgery in adults and construct a risk model.Methods:The convenience sampling method was used to select 620 adult patients undergoing cardiac surgery admitted to the Surgical Intensive Care Unit (SICU) of Zhejiang Provincial People's Hospital from January 1, 2017 to December 31, 2018 as the research object. Patients with postoperative SSD were included in the SSD group, and patients without postoperative SSD were included in the non-SSD group. The preoperative, intraoperative and postoperative clinical data and various indicators of all patients were recorded in detail. Through univariate analysis and binary Logistic regression analysis, the risk factors of SSD after cardiac surgery in adults were explored, and the risk model function was constructed.Results:A total of 569 cases were included in the study. Among them, 399 cases of postoperative subdelirium did not occur (non-SSD group) , 170 cases of postoperative subdelirium occurred (SSD group) , and the incidence of SSD was 29.9%. Univariate analysis found that the influencing factors of adult SSD after cardiac surgery were age, emergency surgery, Acute Physiology and Chronic Health Evaluation (APACHE) Ⅱ score, aortic occlusion time, deep hypothermia circulatory arrest time, intraoperative plasma transfusion, SICU stay time and the use of dexmedetomidine, and the differences between the two groups were statistically significant ( P<0.05) . The binary Logistic regression analysis found that age>76 years [odds ratio ( OR) =4.332, 95% confidence interval ( CI) : (2.103, 8.965) , P<0.001], emergency surgery [ OR=3.453, 95%CI: (1.143, 7.534) , P<0.05], APACHEⅡ score> 15 [ OR=5.453, 95% CI: (1.453, 9.536) , P<0.001], deep hypothermia circulatory arrest time > 34.2 min [ OR=2.132, 95% CI: (1.053, 5.532) , P<0.05] and SICU stay time > 50.0 h [ OR=1.675, 95% CI: (0.832, 5.233) , P<0.05] were independent risks of SSD after cardiac surgery in adults, and the use of dexmedetomidine [ OR=1.536, 95% CI: (0.763, 4.862) , P<0.05] was a protective factor. Conclusions:Age > 76 years, emergency surgery, APACHE Ⅱ score > 15, deep hypothermia circulatory arrest time > 34.2 min, and SICU stay time >50.0 h are independent risk factors for SSD after cardiac surgery in adults, and the use of dexmedetomidine can reduce the occurrence of SSD.

Due to the insufficient education of medical ethics and tending to medical moral educa-tion, the residents lack the ability to make ethical decisions. Therefore, we applied Four Topics method in the clinical ethics training of residents. The clinical ethics training was divided into three stages, and each stage had different training content and objectives. Dongyang People's Hospital adopted the form of lectures and panel discussions. During the group discussion, the group leader was in charge of case preparation, which came from clinical practice, and then all members applied the Four Topics method to analyze and discuss the ethical conflicts, and make the ethical decision. Through this process, residents' ability to solve ethical problems in clinical practice was enhanced.

Objective To quantify the correlations between Elekta XVI cone beam CT dose and various scanning protocols,providing mathematical models to assess the protocol-dependency of imaging dose during imnage guided radiotherapy.Methods Based on standard protocols and various combinations of kVp and mA on an XVI mounted on an Elekta Versa HD accelerator,the air KERMA was measured at various positions in a standard PTW CTDI body phantom using calibrated PTW 30009 kV chamber and UNIDOS webline electrometer.Weighted CT dose index (CTDIw) was computed thereafter.SigmaPlot 10.0 was used to fit the measurements against mA and/or kVp yielding empirical functions.Results Under standard protocols,the CTDIw of Varian OBI was only 11.23％ (chest) and 9.15％ (pelvis) of Elekta XVI.Using the default and other 4 investigated kVp values,the central and peripheral KERMA were both proportional to mA,and vet the slope value a varied dramatically from 0.479 to 6.679.Major affecting factors included kVp settings,measurement locations,and dosimetric mnetrics,etc.None linear regressions were used to fit kVp against KERMA at various locations and CTDIw (R2 ＞ 0.997).The differences between all coefficients were statistically significant (P ＜ 0.05).The impact of changing both mA and kVp on the dose to phantom center can be described as mGy =(5.917-0.197 ×kVp+0.002 × kVp2-5.063 × 10-6 × kVp3) × mA.Conclusions Imaging dose of Elekta XVI is strongly dependent on scanning paraneters.The proposed mathematical models can be used as efficient and robust indicators of such dependency.

HGF group, the pigs received (1×1010 ) pfu of viral titers of Ad-HGF injection. The myocardial perfusion and cardiac function were examined by SPECT, the protein expressions of VEGF165 and HGF were measured by Western blot analysis, cardiomyocyte proliferation was analyzed by immunolfuorescence and immunoprecipitation method.
Results: ① Compared with Control group, the expressions of VEGF165 and HGF were higher at the infarct and peri-infarct zones in both treatment groups; ② Both treatment groups had better cardiac function and myocardial perfusion; ③ Both treatment groups had improved cardiomyocyte proliferation at the infarct and peri-infarct zones.④VEGF165 promoted cardiomyocyte proliferation via p27 pathway;⑤HGF promoted cardiomyocyte proliferation via p21 and p27 pathways.
Conclusion: VEGF165 and HGF could improve myocardial perfusion and function in experimental porcine after MI, VEGF165 and HGF promote cardiomyocyte proliferation via different pathways.

OBJECTIVE: To explore the best time of intratympanic dexamethasone injection to treat sudden sensorineural hearing loss (SSNHL) as salvage therapy so that to improve the curative efficacy on sudden deafness at the utmost. METHOD: A total of 192 patients with SSNHL were included in this study, among whom 63 cases received the systemic steroid therapy throughout the study, while the other ones were treated with systemic steroid as initial treatment and were given intratympanic steroid administration as salvage treatment starting at different time point. The salvage treatment started on the 3rd day after the beginning of the initial treatment for 29 cases, on the 7th day for 38 cases, on the 14th day for 43 cases, and 1 month later for 19 cases. All the patients were followed up for 2 months. RESULT: The recovery rates and total effective rates showed no statistically significant difference between the patients received only systemic steroid therapy and the ones received intratympanic steroid administration on the 3rd, 7th day and 1 month later after the initial treatment. The recovery rate and total effective rate exhibited statistically significant difference between the patients received intratympanic steroid administration since the 14th day after the initial treatment and the ones received only systemic steroid therapy, with the numerical value of P 0. 037 and 0. 034, respectively. CONCLUSION (1) As an initial management plan, the curative effects. between the intratympanic steroid administration and the systemic steroid therapy were not significantly different. (2) As a salvage treatment, intratympanic steroid was a better choice for patients who have not completely recover from ISSNHL after failure of initial management with systemic steroid only. (3) The best time point of salvage treatment with intratympanic steroid was about 2 weeks after initial management with systemic steroid.
