Objective:To survey the continuing medical education training needs for village doctors in Beijing suburbs.Methods:A qualitative study on the continuing medical education training needs for village doctors was conducted in Beijing Huairou district from March to July 2021. Six township hospital managers, 19 village doctors, 15 village cadres and 30 villagers from 15 villages of 3 townships in the district selected by purposive sampling method attended the face-to-face, individual, in-depth interviews. A semi-structured interview outline was developed based on literature review and expert consultation. The content of the interviews was analyzed by the thematic framework method.Results:Among 19 rural doctors, 11 preferred the full-time training, while 8 were unable to participate in the full-time training. Most of township hospital managers and village doctors thought the ideal form of training was "classroom knowledge teaching teaching" (5/6, 16/19)and "outpatient clerkship"(6/6, 13/19). The training contents for village doctors were basic medical knowledge and skills, including diagnosis and treatment of common diseases, identification of common symptoms and management of chronic diseases; the appropriate techniques of traditional Chinese medicine including acupuncture, moxibustion, cupping and scraping; and public health including epidemic prevention and control, infectious disease detection and reporting.Conclusion:For improving the applicability and practicality of training for village doctors, it is necessary to apply rational training methods and forms, and develop targeted training program and contents based on training needs.

Objective:To seek the effect of group education under the BOPPPS model(bridge-in, objective, pre-assessment, participatory learning, post-assessment, summary) on the breastfeeding competency of first gestation women, to improve the breastfeeding competency of first gestation women and promote the realization of postpartum breastfeeding.Methods:Eighty-one first gestation women were chosen from the gestation class of the First Affiliated Hospital of Shanxi Medical University, the quasi-experimental research method was adopted, 40 women from January to February 2022 were involved in the control group and 41 women from May to June 2022 were involved in the intervention group. The control group was assigned common education, while the intervention group was assigned group education based on BOPPPS model. Breastfeeding Competency Scale (BCS) and breastfeeding family support questionnaire were used to compare breastfeeding competency and family support level of the two groups before and after intervention, and the skin contact rate at 1 hour after delivery and the pure breastfeeding rate at 42 days after delivery were compared between the two groups.Results:Before intervention, there was no significant difference in breastfeeding competency and family support level between the two groups (all P>0.05). After 4 weeks of intervention, the scores of breastfeeding competency and family support were (147.59 ± 13.50), (3.16 ± 0.18) points in the intervention group, more than those in the control group (125.48 ± 16.87), (2.87 ± 0.22) points, the differences were statistically significant between the two groups ( t=-6.52, -6.30, both P<0.05). The skin contact rate at 1 hour after delivery and the pure breastfeeding rate at 42 days postpartum were 75.6%(31/41), 53.7%(22/41) in the intervention group, more than those in the control group 52.5%(21/40), 30.0%(12/40), the differences were statistically significant between the two groups ( χ 2=4.71, 4.65, both P<0.05). Conclusions:Group education based on BOPPPS model can improve the level of breastfeeding competency and family support of gestation women. It increases the skin contact rate, and plays a good role in promoting the increase of pure breastfeeding rate.

Objective: To explore the effect of improving these traits through art therapy group meetings as a form of psychological counseling, so as to promote mental wellness among this population. Methods: A total of 74 hearing impaired students from grades 3 to 9 were surveyed with the Children s Self concept Scale (PHCSS) and Social Adaptability Scale. Eight art therapy group meetings, as a form of psychological counseling, were then held. Results: Self consciousness among hearing impaired students aged 10-12 and 13-16 years old was significantly lower than the national norm ( t =-6.51, -8.50, P <0.01). The social adaptability level of this group was very poor(2.89±8.26), and a significant positive correlation was found between self awareness and social adaptability among hearing impaired students. Further, self awareness could predict the social adaptability of these students ( F = 9.04 , P <0.05). After group psychological counseling intervention, there was significant increases in self consciousness among students from grades 3 to 9, and significant increases were also found in the social adaptability of students in grades 3, 4, 5, 6 and 8 ( P <0.05). Conclusion Self awareness shows certain influence on the social adaptability level of hearing impaired students, and group psychological counseling can promote social adaptability by improving self awareness among this population.

Objective:To investigate the application value of contrast-enhanced ultrasound (CEUS) combined with thyroid imaging reporting and data system (TI-RADS) classification in the differential diagnosis of benign and malignant thyroid nodules.Methods:The clinical data of 157 thyroid nodules from 122 participants who underwent conventional ultrasound and CEUS examination from January 2016 to January 2017 in the First Hospital of Shanxi Medical University, China were collected. The image features were analyzed for conventional ultrasound and TI-RADS classification. According to CEUS results, the thyroid nodules were classified by TI-RADS. Based on pathological results, the efficacy of CEUS combined with TI-RADS classification versus conventional ultrasound combined with TI-RADS classification in the differential diagnosis of benign and malignant thyroid nodules was investigated. Results:The area under the curve of CEUS combined with TI-RADS classification (AUC = 0.900) was greater than that of conventional ultrasound combined with TI-RADS classification (AUC = 0.808). The sensitivity, specificity, accuracy, positive and negative predictive values of conventional ultrasound combined with TI-RADS classification in the differential diagnosis of benign and malignant thyroid nodules were 81.6% (80/98), 67.8% (40/59), 76.4% (120/157), 80.8% (80/99), 68.9% (40/58), respectively. They were 98.0% (96/98), 78.0% (34/59), 90.4% (142/157), 88.1% (96/109), 95.8% (46/48), respectively for CEUS combined with TI-RADS classification. The sensitivity of CEUS combined with TI-RADS classification in the differential diagnosis of benign and malignant thyroid nodules was significantly higher than that of conventional ultrasound combined with TI-RADS classification ( χ2 = 12.50, P < 0.001). Conclusion:CEUS combined with TI-RADS classification is more effective in the differential diagnosis of benign and malignant thyroid nodules than conventional ultrasound combined with TI-RADS classification.

Objective:To evaluate the prognostic value of transthoracic lung ultrasound comet-tail and extravascular lung water index (EVLWI) in septic patients.Methods:A prospective cohort study was conducted. Sixty septic patients admitted to department of intensive care unit (ICU) of Sichuan Provincial People's Hospital from November 2016 to October 2019 were enrolled. The EVLWI and pulmonary vascular permeability index (PVPI) were determined by pulse-indicated continuous cardiac output (PiCCO) system at 0, 24, 48 and 72 hours. At the same time, the numbers of comet tail signs in both lungs (parasternal, midclavicular, axillary to midaxillary) were collected by chest ultrasound. Moreover, arterial blood gas analysis, such as pH value, central venous-to-arterial carbon dioxide difference (Pcv-aCO 2), central venous oxygen saturation (ScvO 2), blood lactic acid (Lac), PaO 2/FiO 2 were measured. Pearson correlation analysis was performed between the number of comet-tail sign and EVLWI. Multivariate Logistic regression model was used to analyze the relationship between the number of comet-tail sign, EVLWI and prognosis. Receiver operator characteristic curve (ROC curve) was drawn to predict the prognosis. Results:There were 43 males and 17 females in 60 septic patients. The average age was (64.3±15.5) years old (range: 31-83 years old). There were 35 cases with pulmonary infection, 10 cases with abdominal infection, 6 cases with urinary tract infection, 3 cases with skin and soft tissue infection, 3 cases with intestinal infection, 1 case with meningitis, 1 case with cellulitis and 1 case with multiple injury. Acute respiratory distress syndrome (ARDS) occurred with 8 patients; 40 patients (66.7%) survived and 20 patients (33.3%) died on day 28. Pearson correlation analysis showed that the number of comet-tail sign was positively correlated with EVLWI ( r = 0.944, P < 0.001). There was significant difference in the number of comet-tail signs among sepsis patients with different primary infection sites ( H = 17.714, P < 0.001). The number of comet-tail signs in sepsis patients with pulmonary infection [19 (13, 27)] was significantly higher than that with other infections. The number of comet-tail sign in patients with ARDS was significantly higher than that in patients without ARDS [27 (19, 30) vs. 15 (9, 24), H = 25.387, P < 0.001]. Multivariate Logistic regression analysis showed that EVLWI, the number of comet-tail signs and PVPI were independent risk factors for death in septic patients [odds ratio ( OR) and 95% confidence interval (95% CI) were 10.772 (1.161-99.851), 2.360 (1.070-5.202), 2.042 (1.152-3.622), all P < 0.05]. The accuracy, sensitivity, specificity, positive predictive value, negative predictive value of Logistic regression model based on comet-tail sign and EVLWI were 90.0%, 90.0%, 90.0%, 81.8%, 94.7%, respectively, and area under curve (AUC) were 0.926±0.018, 95% CI was 0.912-0.975, P < 0.001. Conclusions:The transthoracic lung ultrasound comet-tail in septic patients is significantly correlated with EVLWI monitored by PiCCO. The transthoracic lung ultrasound comet-tail combined with EVLWI can better improve the sensitivity, specificity and accuracy of 28-day prognosis in septic patients.

Objective:To evaluate the diagnostic value of metagenomics next-generation sequencing (mNGS) in detecting pathogens in bronchoalveolar lavage fluid (BALF) for pulmonary infection in solid organ transplant patients in intensive care unit (ICU).Methods:A retrospective study was conducted, the BALF samples from 46 patients with post organ transplant pneumonia/suspected pneumonia admitted to the Department of Critical Care Medicine of the First Affiliated Hospital of University of Science and Technology of China from August 2018 to August 2021 were collected, all tested by simultaneous mNGS and conventional comprehensive microbial test (CMT), and the results of CMT were used as the reference standard to compare the differences in the diagnostic value of mNGS and CMT for pulmonary infections in solid organ transplant patients, and to analyze the diagnostic value of mNGS for mixed infections.Results:① Pneumonia pathogens: a total of 31 pathogens were detected in 35 patients, including bacteria (16 species), fungi (9 species) and viruses (6 species). Among them, 25 pathogens were detected by mNGS and CMT, and only 19 pathogens were detected by mNGS. Among the microorganisms isolated by mNGS method, the detection rates of Pseudomonas aeruginosa, Acinetobacter baumannii and Klebsiella pneumoniae were higher [51.4%(18/35), 42.9% (15/35), 31.4% (11/35), respectively]; Candida albicans, Aspergillus and Pneumocystis carinii were the most commonly detected fungi [31.4% (11/35), 22.9% (8/35), 22.9% (8/35), respectively]; 20 patients were positive for the virus, and the most commonly detected viruses were cytomegalovirus, herpesvirus and EB virus [28.6% (10/35), 20.0% (7/35), 17.1% (6/35), respectively]. In addition, one case of Brucella was detected by mNGS.② Diagnostic efficiency: as far as bacterial detection is concerned, 20 cases of negative results were obtained by CMT detection of 35 samples included in the study, and a total of 10 cases of positive results were obtained by mNGS detection of negative samples; the percentage of mNGS positive samples was significantly higher than that of CMT positive samples [odds ratio ( OR) = 5.5, 95% confidence interval (95% CI) = 1.2-24.8, P = 0.02]. When compared with CMT, the sensitivity and specificity of mNGS were 93.3% and 50.0%, and the positive predictive value (PPV) and negative predictive value (NPV) were 58.3%, 91.1%. As far as fungal detection was concerned, there was no significant difference in the percentage of positive samples between the two methods ( OR = 1.5, 95% CI = 0.5-4.2, P = 0.60); the sensitivity and specificity of mNGS were 72.2% and 64.7%, and the PPV and NPV were 68.4%, 68.8%; CMT test of the 35 included samples produced 17 negative results, and mNGS test of the negative samples produced 6 positive results. A total of 20 patients tested positive for the virus by mNGS. In addition, 23 patients (65.7%) were diagnosed with pulmonary mixed infection. Conclusion:The use of mNGS to detect pathogens in BALF can improve the sensitivity and specificity of bacterial identification of pulmonary infection in critically ill organ transplant patients, and mNGS has obvious advantages in detecting virus and identifying mixed infections.

Organ transplantation is an effective treatment for end-stage organ failure. However, organ shortage has always been a common problem faced by countries around the world. The recognition and active participation of intensive care unit (ICU) medical staff in organ donation contributes to promoting the development of organ donation, thereby alleviating the shortage of donor organ. In this article, the key strategies of ICU donor management to promote organ donation and the key strategies of ICU medical staff management to promote organ donation were summarized, aiming to provide reference for organ donation practitioners (especially ICU medical staff) and jointly facilitate the professional development of organ donation.

Objective To investigate the effect of Osthole on memory function of sleep deprivation(SD) mice. Methods Forty-eight male mice were randomly divided into 4 groups;normal control group(NC group ), large platform control group(TC group),sleep deprivation group(M group)and Osthole group(Ost group). The model of SD in mice was estabished by using improved multi platform method. The ability of learning and memory was tested by using Morris water maze test and pathological changes of hippocampal neurons in mice were observed by HE staining. The serum,hippcampus malondialdehyde(MDA)contents and superoxide dismutase(SOD)activity, so as the hippocampus No content,were detected. Results Compared with NC group and TC group,the escape la-tency of M group increased significiantly and the number of crossing platform decreased significantly. There were in-creased levels hippocampus tissue,serum MDA level,hippocampal SOD activity and NO content. After supplemen-tation of Osthole,the escape latency significantly shortened in mice. The number of crossing platform was increased while the contents of MDA both in hippocampus and serum were decreased,and the SOD activity in hippocampus re-turned to normal. However,the level of NO in hippocampus was not decreased. Conclusion Osthole can protect the memory function of SD mice by reducing the the damage of hippocampal neurons through antioxidant stress.
