Methods The clinical data of three patients with pulmonary aspergillosis from January to April 2010 were retrospectively analyzed, and the misdiagnostic causes were analyzed. Result No specific clinical and imaging findings were found in the three patients, and pulmonary aspergillosis was finally diagnosed according to the pathological biopsy. Conclusion Pulmonary aspergillus lacks specific clinical and imaging manifestations; early fiberoptic bronchoscopy or pulmonary biopsy may improve the rate of accurate diagnosis.
Objective To explore the application effect of the four-dimensional teaching library model in the training of neuroinfection subspecialty continuing physicians, and compare it with traditional rotational training. Methods Continuing physicians who received training in the Department of Neurology of Xuanwu Hospital, Capital Medical University between March 2021 and February 2023 were selected. The continuing physicians who received traditional rotational training between March 2021 and February 2022 would serve as the control group, and the continuing physicians who received four-dimensional teaching library model training between March 2022 and February 2023 would serve as the experimental group. The Mini-CEX scale was used to evaluate the clinical comprehensive abilities of two groups of continuing physicians. At the same time, self-made questionnaires were used to evaluate the evaluation of two groups of continuing physicians on different teaching modes. Results A total of 55 continuing physicians were included. Among them, there were 27 people in the control group and 28 people in the experimental group. There was no statistically significant difference in the comparison of general information between the two groups (P＞0.05). At the time of graduation, all items on the Mini-CEX scale in the experimental group were higher than those in the control group (P<0.05). The survey questionnaire results showed that the experimental group scored higher than the control group in terms of improving learning interest, improving self-learning ability, improving clinical thinking, improving analysis and problem-solving ability, improving doctor-patient communication ability, and increasing teamwork (P<0.05). Conclusion The application effect of the four-dimensional teaching library model in the training of neuroinfection subspecialty continuing physicians is better than that of traditional rotational training, which can significantly improve the clinical comprehensive ability of continuing physicians and is worth promoting.
在過去二十年間，麻醉技術和手術技術的改進使肺部惡性腫瘤患者的手術死亡率大大降低，但術后并發癥仍是主要問題。肺切除術后的常見并發癥是肺部并發癥[1]，主要表現是低氧血癥，尤其在肺功能減退的肺切除患者中發病率更高[2]。目前國內對低氧血癥的診斷缺乏統一的診斷標準，一些作者采用Russell等[3]提出的標準，吸空氣氧的情況下，患者動脈血氧飽和度（SpO2）≤92%，大于30 s就可診斷為術后低氧血癥。也有作者建議[4]將一次或以上血氣檢查PaO2lt;8 kPa或PaO2/FiO2lt;300 mm Hg（1 mm Hg=0.133 kPa）作為診斷低氧血癥的標準。30%~50%的術后患者可發生低氧血癥，一般認為這樣的低氧血癥是一過性的，對大多數患者是無害的[5]。但如果合并心腦或其他器官動脈硬化或其他原因的血管阻塞，這種低氧血癥就是很危險的[6]。常見低氧血癥的原因是肺萎陷不張和誤吸、心源性肺水腫、靜脈輸入液體過量、通氣血流比例失調和急性肺損傷/急性呼吸窘迫綜合征（ALI/ARDS）[7]，其中ALI/ARDS是肺切除術后患者死亡的主要原因[8-10]。
Hot topics on the diagnosis and antimicrobial therapy of ventilator-associated pneumonia, including clinical diagnostic criteria, evaluation of biomarkers, ventilator associated events, clinical pulmonary infection score, ventilator-associated tracheobronchitis, microbiological diagnosis and duration of therapy were discussed. The viewpoints in the guidelines of America, Europe and Japan were also reviewed.
Researches in evidence-based medicine have provided important evidence for family planning doctors to guide their clinical practice. With examples of clinical researches, the practical methods of evidence-based medicine in family planning service are discussed in this paper.
ObjectivesTo understand the current situation of the nosocomial infection management system in maternal and child health care institutions at all levels in Sichuan province, and provide a feasible policy basis for strengthening the nosocomial infection management.MethodsThe expert group members of Sichuan Maternal and Child Health Association Academy Association designed a unified questionnaire, and distributed the questionnaire through “Questionnaire Star” to carry out on-site online survey.ResultsA total of 159 maternal and child health care institutions participated in the survey. Most secondary and below maternal and child health care institutions had not set up professional hospital infection monitoring system. A few secondary and below maternal and child health care institutions did not independently set up a hospital infection management committee, hospital infection management department, full-time hospital infection department head, the inspection team of infection control, monitoring system, and nosocomial infection management system and special supervision had not been established in special departments. There were statistical differences in some jobs in the construction of nosocomial infection management system in different levels of maternal and child health care institutions (P<0.05).ConclusionsThe organizational system construction of hospital infection managemen are at a low level in the second level and below maternal and child health care institutions in Sichuan province. The tertiary maternal and child health care institutions should give full play to the leading role in promoting the standard construction of nosocomial infection management system of maternal and child health care institutions in Sichuan province, and carry out nosocomial infection management of maternal and child health care institutions orderly.
This study aims to investigate the value of pre-treatment computed tomography (CT) texture analysis in predicting therapeutic response of liver metastasis from colorectal cancer after combined targeting chemotherapy. A total of 82 patients with colorectal cancer liver metastases who underwent chemotherapy combined with targeted therapy (cetuximab) between March 2011 and October 2017 comprised this retrospective study population. According to the RECIST1.1, the best curative effect evaluation of patients was recorded. Complete response (CR) and partial response (PR) were assigned to the response group, and the stable disease (SD) and progressive disease (PD) were assigned to the non-response group. The CT texture analysis was based on the Omini-Kinetics software, and the three-dimensional (3D) texture analysis was performed on the marked lesion on portal phase. The differences of texture parameters between the response group and the non-response group were compared. The receiver operating characteristic (ROC) curves were depicted on the parameters which with statistically difference, to characterize value in predicting the response to target-combined chemotherapy. The differences of Entropy, Energy, Variance, std. Deviation, Quantile95 and sumEntropy between the two groups in pre-treatment lesions were significant (P < 0.05). And lesions with higher Entropy, lower Energy, higher Variance, higher std Deviation and higher sumEntropy seemed to indicate a better therapeutic response. When sumEntropy > 0.867, good diagnostic efficiency could be obtained, with sensitivity of 60.5% and specificity of 79.5%, respectively. In conclusion, texture parameters derived from baseline CT images of colorectal cancer liver metastasis have the potential value acting as imaging biomarkers in predicting tumor response to combined target chemotherapy.
Objective To investigate the clinical characteristics of primary malignant tumors of the left atrium and the late results of surgical treatment. Methods The clinical experience with surgical treatment of 13 primary malignant tumors of left atrium was analyzed retrospectively. Complete resection of malignant tumor was achieved in 7 cases(53.8％ )，and subtotal resection was achieved in 3 cases(23.0％), only biopsy was performed in 2 patients(15.4％ )because of extensive metastasis of tumor. Heart transplantation was performed in 1 case(7.7％). Results There was no hospital death. The pathological diagnosis was undifferentiated sarcoma in 5 cases, leiomyosarcoma in 2 cases, malignant transformation of myxoma in 2 cases, angiosarcoma in 1 case, fibrosarcoma in 1 case, malignant fibrous histocytoma in 1 case and malignant hemangiopericytoma in 1 case. There were 11 patients followedup for 3 months to 65 months and showed 9 late death due to recurrence or metastasis. There was 2 patients lost of follow-up. Conclusion Primary malignant tumors of the left atrium should be resected to relieve symptoms caused by local tumor growth. Surgery provides control of primary tumor and allows the potential for cure or longterm survival with effective adjuvant therapy. The prognosis of these patients is still poor.
