Objective:To explore the feasibility and application value of an automated method for generation of surgical records for resection of benign soft tissue tumor based on dense video descriptions.Methods:The Transformer deep learning model was used to establish an automated surgical record generation system to analyze the surgical videos of 30 patients with benign soft tissue tumor who had been admitted to Department of Orthopedics, Xijing Hospital, Air Force Military Medical University from September 2021 to August 2023. The patient data were randomly divided into training sets, validation sets, and test sets in a ratio of 8∶1∶1. In the test sets, 7 evaluation indexes, BLEU-1, BLEU-2, BLEU-3, BLEU-4, Meteor, Rouge, and CIDEr, were used to evaluate the text quality of surgical records generated by the model. The text of surgical records was compared with the classical algorithm, dense video captioning with paralled decoding (PDVC) in the field of video-intensive description.Results:The automated surgical record generation system running in the test sets showed the following: BLEU-1, BLEU-2, BLEU-3, BLEU-4, Rouge, Meteor, and CIDEr were 16.80, 15.23, 13.01, 11.68, 16.01, 12.67 and 62.30, respectively. The operation of the classical algorithm PDVC showed the following: BLEU-1, BLEU-2, BLEU-3, BLEU-4, Rouge, Meteor, and CIDEr were 15.63, 14.17, 11.90, 10.45, 12.97, 11.99 and 53.64, respectively. The automated surgical record generation system resulted in significant improvements compared with PDVC in all evaluation indexes. The BLEU-4, Rouge, Meteor, and CIDEr were improved by 1.23, 3.04, 0.68 and 8.66, respectively, demonstrating that the system proposed can better capture the key data in the video to help generate more effective text records.Conclusion:As the automated surgical record generation system shows good performance in generating surgical records for resection of benign soft tissue tumor based on intensive video descriptions, it can be applied in clinical practice.

Objective:
Based on the KAP and Prospect theory, to explore, construct and verify the theoretical model and formation mechanism of driving factors of primary care doctors′ willingness to carry out the primary diagnosis.
Methods:
Using the random cluster sampling method, from April to May 2019, a questionnaire survey was conducted among doctors at 20 primary medical and health service institutions in Hangzhou. The survey covered the primary care doctors′ cognition level of primary diagnosis, their self-evaluation of primary medical care capabilities, evaluation of policies and systems, expectation of primary medical care, and their job satisfaction. Descriptive statistic, multiple linear regression and structural equation model were used to analyze and explore the driving factors and formation mechanism of their willingness to carry out the primary diagnosis.
Results:
Primary care doctors′ willingness rate for primary diagnosis was 76.4%(308/403). Positive expectation(beta=0.309), cognition level(beta=0.216), evaluation of policies and systems(beta=0.184), and self-evaluation of primary diagnosis capability(beta=0.170), all of which directly affect the said willingness. The total effect of the five types of driving factors on the willingness of the primary diagnosis was as follows: cognitive level of the primary diagnosis(0.536), evaluation of the policy system(0.494), self-evaluation of the primary diagnosis capability(0.436), positive expectations of the primary diagnosis work(0.186), job satisfaction(0.146).
Conclusions
The cognition of the primary diagnosis, the capability of the primary diagnosis, the policy system and the positive expectation are the important premises, key driving forces, and a strong guarantee and motivation to drive primary care doctors to carry out the primary diagnosis. It is suggested that the government and medical institutions should further improve the cognition level of primary care doctors, focusing on systematically improving the service capability of primary care doctors′ primary consultation, coordinating to improve policy guidance measures such as financial input, medical insurance reimbursement and referral system, establishing and improving incentive measures such as career development, performance appraisal, salary and welfare of primary care doctors.

OBJECTIVETo analyze the epidemiology data on plague in five counties in Zhejiang province and to evaluate the risk of plague in theses areas.
METHODSWe selected five monitoring stations as a risk assessment (Qingyuan county, Longquan city, Yiwu city, Wencheng county, and Ruian city) in Zhejiang province where the plague epidemic more serious in the history. At least one constant site and 1-4 variable sites where plague occurred in history were selected for monitoring. We collected the five counties (cities) surveillance data of indoor rat density, indoor Rattus flavipectus density, the Xenopsylla cheopis index of rat, the Xenopsylla cheopis index of Rattus flavipectus in 1995-2014. Isolation of Yersinia pestis was conducted among 171,201 liver samples and F1 antibody were detected among 228,775 serum samples. Risk matrix, Borda count method, and Delphi approach were conducted to assess risk of the plague of five counties (cities) in Zhejiang province.
RESULTSIndoor rat density in Qingyuan county, Longquan city, Yiwu city, Wencheng county, Ruian city was 1.58%-5.50%, 1.13%-9.76%, 0.56%-3.67%, 2.83%-16.08%, 7.16%-15.96%, respectively; Indoor Rattus flavipectus density of five counties (cities) was 0.08%-2.23%, 0-2.02%, 0-0.54%, 0.71%-5.58%, 0.55%-4.92%, respectively. The Xenopsylla cheopis index of rat in Qingyuan county and Wencheng county was 0.011-0.500 and 0.015-0.227, respectively; The Xenopsylla cheopis index of Rattus flavipectus of Qingyuan county and Wencheng county was 0.119-3.412 and 0.100-1.430, respectively; Ruian City and Yiwu city cannot collected Xenopsylla cheopis, Long quan city only collected the Xenopsylla cheopis index of rat in the five years. Yersinia pestis were not isolated in five counties (cities).There were 3 Apodemus agrarius samples positive of plague F1 antibody test, in Longquan city and Yiwu city in 2005. Borda count method to assess the Longquan city, Yiwu (Borda point were both 321) plague risk was higher than three other regions; Delphi approach to evaluation five counties (cities) belong to the plague had a lower risk areas, according to the level of risk score (Pf) Longquan city and Yiwu (Pf was 0.314, 0.292, respectively) plague risk were higher than three other regions (Pf were all 0.292).
CONCLUSIONThe main host and media were lower in five key plague surveillance counties (cities) of Zhejiang province; The result of Borda count method and Delphi approach for risk assessment indicated that endogenous plague recrudescence was at lower level, but Longquan city and Yiwu city risk were higher than other counties (cities).

Objective To investigate the safety and clinical effect of endovascular radiofrequency ablation (RFA) catheter, the HabibTM VesOpen, in treating portal vein tumor thrombus. Methods Fifteen patients of hepatocellular carcinoma associated with portal vein thrombus causing obstruction of blood flow were enrolled in this study. Guided by ultrasound percutaneous portal catheter implantation was performed, then, under DSA guidance RFA catheter was placed at portal vein tumor thrombus. RF generator (RITA) was connected to the electrodes, the power was set at 10 W for 2 - 10 minutes. The technical success rate, the postoperative complications, the hepatic and renal functions as well as routine blood tests, portal vein blood flow and the ablation extent of portal vein tumor thrombus were evaluated, and the results were analyzed. Results The procedure was successfully accomplished in all patients. No technique-related complications, such as hemorrhage, vessel perforation, bile leak complicated by infection, liver abscess, abdominal bleeding occurred. Direct portography performed immediately after RFA showed that the portal vein was re-opened. Laboratory examinations performed 4 weeks after RFA showed that no obvious changes in hepatic functions and routine blood tests were observed. Doppler ultrasound examinations revealed that flowing blood was obviously displayed within previously obstructed portal vein. CT scanning was carried out in some patients with portal vein thrombus, and it indicated that the portal vein tumor thrombus was reduced in size or even disappeared. Conclusion For the treatment of portal vein tumor thrombus in patients with hepatocellular carcinoma, endovascular radiofrequency ablation is technically feasible, and the initial results indicate that this technique is an effective treatment.

The inhibitory ratio (1%) of artificial musk on cyclooxygenase-2 (COX-2) was determined by enzyme immunoassay (EIA). The dose-effect relationship between concentrations of artificial musk and 1% was established. It was found that artificial musk had obvious inhibitory action on COX-2. The concentration for 50% of maximum inhibitory effect (IC50) was about 2.26 mg x mL(-1). There was a good relationship between the logarithm concentrations of artificial musk and 1% when the concentrations of artificial musk ranged from 0.31-20.0 mg x mL(-1). The results indicated that this EIA method could be applied to evaluate the anti-inflammatory activity of artificial musk quickly, conveniently, sensitively and exactly. This paper provided a novel method and foundational research for the bioassay of artificial musk.
