Objective:To explore the correlation between subclavian artery stenosis disease (SASD) classification and posterior circulation ischemia.Methods:A retrospective study was performed; the clinical data, and Doppler vascular ultrasound and vascular imaging results of 81 SASD patients, admitted to Cerebrovascular Stenosis Diagnosis and Treatment Center, Second Affiliated Hospital of Qiqihar Medical College and Department of Neurology, Rocket Force Specialty Medical Center from May 2018 to August 2023, were collected. SASD was categorized into 2 types (single type and concurrent type) based on the presence or absence of other posterior circulation artery (basilar artery, vertebral artery, or subclavian artery distal segment) stenosis/occlusion, and into 3 groups (non-posterior circulation ischemia group, posterior circulation transient ischemic attack group and posterior circulation cerebral infarction group) based on the presence or absence of posterior circulation ischemia. Blood stealing pathways in different SASD classifications were analyzed, and correlation of SASD classification with posterior circulation ischemia was discussed.Results:Single-type SASD was noted in 44 patients (54.3%), mainly initiating blood stealing through the vertebral artery to the vertebral artery and then to the subclavian artery ( n=26); concurrent-type SASD was noted in 37 patients (45.7%), mainly initiating blood stealing through the occipital artery to the costocervical trunk and then to the subclavian artery ( n=10). Sixty-five patients (80.2%) were into the non-posterior circulation ischemia group, 4 (4.9%) into the posterior circulation transient ischemic attack group and 12 (14.8%) into the posterior circulation cerebral infarction group. Among the 44 patients with single-type SASD, 39 did not have posterior circulation ischemia, and 3 had posterior circulation cerebral infarction. Among the 37 patients with concurrent-type SASD, 26 did not have posterior circulation ischemia, and 9 had posterior circulation cerebral infarction. Conclusion:Initiation of blood stealing in SASD patients is related to SASD classification, and concurrent-type SASD patients trend to have posterior circulation ischemia.

The incidence and mortality of lung cancer ranked the first in China. China had 787, 000 new cases of lung cancer in 2015, and a majority of these patients with advanced lung cancer. With the development and popularization of high-resolution computed tomography, more and more early-stage lung adenocarcinomas are found in screening. The imaging finding of early-stage lung adenocarcinomas often manifests as part solid nodule (PSN) containing ground glass opacity (GGO). Although the imaging manifestation of the nodules can′t accurately predict the pathologic type of nodules, the parts of solid nodule and GGO still have some pathologic indications, and the prognostic evaluation effect of the maximum diameter of PSN is superior to that of the whole nodule. With the development of the molecular radiography and molecular pathology, the relationship of imaging manifestation of the PSN and metastasis were focused on. Some PSNs with special nature are more active and rapidly progressed than the pure GGOs. While compared to the pure solid nodules, the aggressiveness of PSNs are insufficient, with lower metastatic rates of lymph node and better prognoses. Currently, international acknowledge recommends to take active intervention measure for PSNs which are highly suspected to be malignant. We focus on the diagnosis and treatment of PSNs, systemically depict their staging, follow-up, surgical treatment, gene detection and immunotherapy.

Objective: To investigate the implementation of disease prevention and control services at tertiary public general hospitals in Beijing for providing evidences to explore and build a scientific evaluation model of disease control service in medical institutions. Methods: June to September 2018, through a questionnaire survey of 50 tertiary public general hospitals in Beijing, a descriptive analysis was made on the department setting, personnel allocation and service provision status of disease prevention and control at tertiary public general hospitals in Beijing. Results: Among the 44 investigated public tertiary general hospitals, 26(59.1%) medical institutions have set up departments of disease prevention and control. The average staffing of 44 hospitals was 5.8 persons for the department. Professional composition of the staff was mostly nursing and clinical disciplines, and the academic and professional titles were mostly undergraduate and intermediate degrees respectively. Overall performance of disease prevention and control services in public tertiary general hospitals was satisfactory. The work was well carried out in communicable disease control and death-surveillance management, namely in immunoprophylaxis, chronic noncommunicable diseases and injury monitoring, which varies widely in mental health services, occupational health management, environmental and health monitoring and other functions. Conclusions Professional ability and management level of personnel still need to be improved. We should further clarify the joint prevention and control mechanism of the " Three-in-one" nature of disease control institutions, medical institutions and communities, promote the combination of medical treatment and prevention, and explore the classification and grading evaluation of disease control work based on the types and quantity requirements of disease prevention and control services undertaken by hospitals, so as to effectively improve the level of disease control services in hospitals.

Objective: To explore the establishment of an evaluation indicator system for disease prevention and control workload at public hospitals, based on the current situation of disease prevention and control work undertaken by public hospitals of and above secondary level in Beijing, and to provide evaluation assistance for them to do better in this regard. Methods: This research was based on our pervious study of the current situation description of disease prevention and control work undertaken by public hospitals in Beijing, by which the contents of routine disease prevention and control work at hospitals have been initially established. The unit strength of each work was consulted, and the disease prevention and control work was classified according to the results. Meanwhile the consistency test of the work intensity within the category was carried out. After integration, the classification and evaluation indicator of disease prevention and control work in public hospitals of and above secondary level in Beijing was finally established. Results: The workload evaluation indicator system was divided into eight parts: report work, report quality control work, monitoring work, training work, work of public health related clinical diagnosis and treatment, work of clinical examination and vaccination, work of sampling and testing and public health related consultation work. The work intensity of each category ranged from 4.78 to 7.34. Conclusions The evaluation indicator system of workload is suitable for the evaluation of basic works. The unified transformation of workload by using the value of work intensity is conducive to management evaluation, but the limitation of the indicators exists in time and region, making it necessary to adjust by the local specific situation at the promotion and application level.

Pelvic abscess is one of the most common gynecologic acute abdomen.It is often developed by pelvic inflammatory disease,and the incidence of the pelvic abscess is rising year by year and younger.It often leads to a variety of diseases,such as infertility,which threaten female reproductive health.Its clinical symptoms vary and progress rapidly,which can easily lead to misdiagnosis or untimely rupture of abscess,and seriously endanger life.For pelvic abscess,correct diagnosis and timely treatment are the fundamental starting point.This article reviews the progress in the diagnosis and treatment of pelvic abscess.

High mobility group protein B1 (HMGB1) is a DNA binding protein that can induce cytokines to be secreted and activate inflammatory cells to participate in inflammatory reactions. Recent studies on its role in the inflammatory response to endometriosis have gradually increased. Endometriosis is a benign inflammatory disease with increasing incidence year by year, mostly in women of childbearing age. This disease mainly causes the clinical manifestations of dysmenorrhea and chronic pelvic pain. Endometriosis usually plays a synergistic role in inflammatory immune, lesion tissue invasion, adhesion and other factors, resulting the changes in the pelvic microenvironment. The mechanism of endometriosis is not completely clear, but the role of inflammatory reaction and stimulation can not be ignored. HMGB1 can increase the release of inflammatory factors and cause the body to produce pain, and the expression of HMGB1 in the endometriosis patients is significantly increased. The inflammatory response and pain can be alleviated by reducing the concentration of HMGB1 in the body of endometriosis patients. Pain and other symptoms suggest that HMGB1 may become an important target for the treatment of endometriosis.

Objective To analyze the risk factors of nosocomial infection in Department of Neurosurgery and to provide evidence for the prevention and treatment of infection.Methods A total of 931 patients with neurosurgery operation in our hospital from January 2012-January 2016 were collected medical history data immediately after admission,including age,gender,underlying diseases,and primary diseases.Surgical records include preoperative white blood cell count,blood glucose level before operation,duration of operation,and reoperation.Hospitalization records include hospitalization time,without the use of corticosteroids,with or without the use of proton there is no pump inhibitor,and tracheal intubation / incision.Patients were divided into infection group and non infection group according to whether the hospital infection occurred during hospitalization.The difference of two groups of clinical data with statistically significant variables was Logistic multivariate regression analysis.Results There were 112 patients with nosocomial infection,the infection rate was 12.03％,and the infection occurred in the postoperative 3-25 d.The main infection site was postoperative wound,accounting for 35.7％;respiratory tract,accounting for 34.8％.There were 64 strains of pathogenic bacteria,81 strains of Gram-negative bacteria,accounting for 64.1％,21 strains of gram positive bacteria,accounting for 32.8％,2 strains of fungi,accounting for 3.1％.There were significant difference between infection group and non infection group in ≥ 60 years,with basic diseases,reoperation,combined with other injuries,white blood cells,abnormal preoperative hyperglycemia,glucocorticoid use,proton pump inhibitors use,tracheotomy,hospitalization time,operation time (P ＜ 0.05).Further Logisitc regression analysis showed that age,reoperation,hospitalization time,preoperative high blood sugar and tracheotomy were the risk factors of nosocomial infection in Department of neurosurgery.Conclusions For the older,reoperation,longer hospitalization time,preoperative hyperglycemia and tracheotomy patients can take specific measures to improve the immunity of the patients,the rational use of antimicrobial drugs to avoid the occurrence of postoperative infection.

Objective:To observe the clinical efficacy of rh-BNP combined with continuous renal replacement therapy on the re-fractory heart failure in cardiorenal syndrome. Methods:Totally 48 patients with refractory heart failure in cardiorenal syndrome in our hospital were selected and randomly divided into the observation group and the control group. The control group was received the con-ventional drug therapy combined with continuous renal replacement therapy, and the observation group was received rh-BNP therapy ad-ditionally. After 7 days, NT-ProBNP, heart rate, LVEF, SV, BUN, Scr and GFR of the two groups were compared, and the clinical efficacy of the two groups was evaluated. Results:After the treatment, all the observed indicators in the two groups were significantly improved than those before the treatment, and the improvement in the observation group was better than that in the control group ( P<0. 05). The total effective rate of the observation group was higher than that of the control group(91. 67% vs 79. 17%, P<0. 05). Conclusion:The combination of rh-BNP and continuous renal replacement therapy can improve heart and kidney function of the refrac-tory heart failure in cardiorenal syndrome with better efficacy.

OBJECTIVETo conduct with a cost analysis of the colorectal neoplasm screening program in Beijing, and provide data evidence for decision making.

METHODSBased on stratified cluster sampling method, we carried out a 2-stage colorectal neoplasm screening program within 6 districts, Dongcheng, Xicheng, Chaoyang, Haidian, Fengtai and Shijingshan, of Beijing city between October, 2012 to May. 2013. The first stage of the program was to conducting a cancer risk level evaluation for community residents who were forty years older and the second stage's task was to providing clinical exam for those high risk people who were selected from the first stage. There were about 12 953 residents were involved in this program. We calculated the main cost of the colorectal neoplasm screen program in Beijing. Then estimate the cost of detecting one Colorectal Neoplasm patient of this program and compare it with the total treatment cost for a patient.

RESULT2 487 high risk residents were selected by the first stage and 1 055 of them made appointment for the colonoscopy exam but only 375 accepted the exam, participate rate was 35.5%. 9 neoplasm cancer patients and 71 pre-cancer patient were found at the second stage, the detection rate were 69.2/100 000 and 546/100 000, respectively. The direct input for this neoplasm screening program was 227 100 CNY and the transport expense was 4 200 CNY in the calculations. The cost for detecting one cancer patient was about 19 900 CNY. Comparing with the total medical care cost of a cancer patient (1 282 800 CNY), especially for those have been diagnosed as middle to end stage cancer, the screening program (cost 842 800 CNY) might help to reduce the total health expenditure about 128 700 CNY, based on 12 953 local residents age above 40 years old.

CONCLUSIONAn colonoscopy based colorectal neoplasm screening program showed its function on medical expenditure saving and might have advantage on health social labor creating.
