ObjectiveTo explore the mechanisms of perineural invasion (PNI) in pancreatic cancer so as to find a new treatment for pancreatic cancer. MethodsThe literatures on PNI, neurotropism, nerve-tumor microenvironment and nerve growth factor in pancreatic cancer were reviewed and the mechanisms of PNI were summarized. ResultsThe rich innervation of pancreatic tissue itself and the minute slits within perineural structure were the anatomic basis of PNI. Tumor cells expressed neural antigens were the pathological basis of PNI. Tumor-nerve microenvironment and nerve growth factor family and themselves receptors might play an important molecular role in PNI. However, tumor cells expressed neural antigens were not only closely related to the PNI, but also the interaction between tumor cells and nerves played an important role in PNI. ConclusionsThe detailed mechanisms of PNI are extremely complex and controversial up to today. However, it is possible to search a new therapeutic target in pancreatic cancer according to the mechanisms of PNI.
ObjectiveTo realize the application status and development trend of oral anticoagulant drugs used in respiratory diseases in 72 hospitals in 6 cities from the year 2013 to 2017.MethodsFrom January 2013 to December 2017, we randomly selected the electronic information from 10 working days per quarter in 6 cities including Beijing, Guangzhou, Shanghai, Chengdu, Shenyang, and Zhengzhou, with 12 hospitals in each city, and summarized the information into the prescription database of the hospital prescription analysis project. Through the hospital information system, we screened out the information of outpatient prescriptions and inpatient medical records which used oral anticoagulants. The prescriptions with respiratory diseases related-diagnosis were selected as the research objects by manual screening. The application of oral anticoagulant drugs used in respiratory diseases was statistically analyzed by drug amount, prescription amount, prescribed daily dose (PDD), and defined daily dose (DDD).ResultsFrom 2013 to 2017, the number of warfarin sodium prescriptions was successively 4 769, 5 747, 7 549, 7 261, and 7 151, which had been always ranked the first in the five years, but decreased year by year since 2015. The proportion of warfarin sodium drug use amount decreased year by year from 32.52% in 2013 to 5.03% in 2017. The proportion of prescription and drug consumption sum of new oral anticoagulants increased year by year in the past five years. The PDD/DDD of warfarin sodium, dabigatran etexilate, rivaroxaban, and apixaban were 0.41, 0.73, 0.68, and 0.33, respectively. There were off lable use of new oral anticoagulants.ConclusionsWarfarin still dominates the proportion of oral anticoagulants prescribed in the 72 hospitals in the 6 cities in the five years. The clinicians have made a comprehensive judgment after fully considering the safety, effectiveness, and economy of drug use when formulating drug treatment programs.
Objective To evaluate the methodological quality of clinical trials on traditional Chinese medicine (TCM) nursing in recent six years.Methods Such databases as CNKI, VIP, WanFang Data and CBM were searched for collecting clinical trials on TCM nursing published from January 2006 to September 2011, and domestic primary nursing journals were also searched from January 2010 and September 2011. Methodological quality of included studies was assessed using quality assessment criteria of the Cochrane systematic review guideline. Results A total of 854 clinical trials were retrieved, including 706 (82.7%) randomized controlled trials (RCTs), 108 (12.6%) quasi-randomized controlled trials and 40 (4.7%) non-randomized controlled trials. In the methodological quality analysis, the comparability of baseline was mentioned in 784 trials (91.8%), a total of 498 (58.3%) reported definite diagnosis criteria. 178 (20.8%) reported exclusive criteria. 831 studies (97.3%) applied relevant statistical methods properly. However, only 55 trials (6.4%) mentioned the method of randomization sequence. 10 studies (1.2%) described the method of randomiztion assignment. Blinding was mentioned in 22 studies (2.6%). 98 trials (11.5%) did prospective follow-up. 93 trials (10.9%) had safety description. 20 trials (2.3%) reported lost and with drawl cases, but only 2 conducted intention-to-treat analysis. It was hard to determine whether there was selective reporting bias or not because all the studies did not have protocols. Only 21 studies (2.5%) mentioned the lack of outcome indicators which could be the evidence for existing of bias. By annual analysis, there were 81 trials which conformed to at least 2 low risk criteria. 10 trials (12.3%) was published in 2009, 26 trials (32.1%) published in 2010, and 27 trials published by September 2011, indicated an uptrend. Conclusions According to the Cochrane Collaboration’s tool for assessing risk of bias, the overall quality of clinical trials on TCM nursing is low with defects in different degrees, but it rises gradually over years.
Objective To evaluate the application effect of quality control circle (QCC) in improving the number of cases received in the follow-up management of chronic kidney disease (CKD). Methods The outpatient and inpatient CKD patients who were filed in the CKD follow-up management center of West China Hospital of Sichuan University from March 10 to October 10, 2020 were selected. We analyzed the reasons that affected CKD patients’ willingness to file by carrying out QCC, improved the case collection by establishing standardized processes, broadened the collection channels, established a collective team, strengthened training management and education of CKD patients and their families, so as to increase the number of cases received in CKD follow-up management. Then, we observed the score of active ability of QCC members before and after this activity. Results After the implementation of QCC activities, the number of follow-up cases increased from 8 per month to 15 per month. The target achievement rate was 140%, and the progress rate was 87.5%. The ability of all circle members in the evaluation indicators of team training has been improved. Conclusions QCC activity can effectively improve the number of cases received in CKD follow-up management. It is helpful for the medical staff to provide better disease management for CKD patients.
ObjectiveTo systematically review the willingness rate of the first consultation in primary health care institutions among Chinese residents.MethodsCNKI, WanFang Data, VIP, PubMed, Web of Science and EMbase databases were electronically searched to collect cross-sectional studies on the willingness rate of the first consultation in primary health care institutions of residents in China from January 2006 to November 2020. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies; meta-analysis was then performed using Stata 14.1 software.ResultsA total of 26 cross-sectional studies involving 36 430 subjects were included. The results of meta-analysis showed that the willingness rate of Chinese residents for the first consultation in primary health care institutions was 61.4% (95%CI 54.5% to 68.3%). The results of subgroup analysis showed that for the willingness rates of the first treatment at the grassroots level in male and female residents were 65.6% and 64.9%; urban and rural residents were 49.9% and 58.9%; <60 and ≥60 years old residents were 60.5% and 71.6%; primary school and below, junior high school, high school or technical secondary school, junior college or above educational level residents were 72.8%, 68.1%, 64.2%, and 52.8%; employees, residents, and other types of insurance residents were 74.1%, 75.9%, and 64.4%; residents with monthly income <3 000, 3 000-5 000, and >5 000 yuan were 65.8%, 65.3%, and 58.5%; high, medium, and poor levels of health status residents were 56.8%, 52.6%, and 48.8%; with and without chronic diseases residents were 61.0% and 56.9%; with and without spouse residents were 63.9% and 64.6%; with and without contracted family doctor residents were 87.1% and 62.6%; on duty, retired, and other employment status residents were 70.7%, 69.9% and 71.5%; primary medical institutions residents those were satisfied, average, and dissatisfied were 77.3%, 60.7%, and 49.4%.ConclusionsCurrent evidence suggests that it remains room for improvement in the level of willingness of Chinese residents for first consultation in primary health care institutions. Residence, age, educational level, type of medical insurance, income level, health level, family doctors contracted status, and satisfaction with primary medical institutions have an impact on residents' willingness to receive first treatment at primary hospitals. Due to limited quality and quantity of the included studies, more high quality studies are needed to verify above conclusions.
ObjectiveTo systematically review the satisfaction of Chinese residents with the contract services of family doctors. MethodsCNKI, WanFang Data, VIP, PubMed, Web of Science, and EMbase databases were electronically searched to collect cross-sectional studies related to the Chinese residents' satisfaction with the service of family doctors from January 2011 to May 2021. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. Meta-analysis was then performed using Stata 14.1 software. ResultsA total of 42 cross-sectional studies were included. The results of meta-analysis showed that the overall satisfaction rate of residents with the contract services of family doctors was 77.7% (95%CI 73.7% to 81.7%). The results of subgroup analysis showed that the satisfaction rate of the male and female residents were 83.0% and 84.3%; <60 and ≥60 years old residents were 83.5% and 81.7%; junior high school or below, senior high school or technical secondary school, junior college or above educational level residents were 84.1%, 76.4% and 81.2%; the monthly income less than 4000 yuan and more than 4000 yuan residents were 78.5% and 79.3%; with and without diseases residents were 85.3% and 79.7%; with and without spouse residents were 80.6% and 82.4%; on and off the job residents were 77.7% and 73.9%; urban and rural residents were 78.7% and 80.0%; in 2011-2015 and 2016-2020 were 67.6% and 76.2%; eastern and western regions residents were 76.5% and 79.7%; relevant studies which were conducted by random sampling and nonrandom sampling were 80.5% and 73.5%. ConclusionsThere is still room for improvement in residents' satisfaction with family doctor contract service. Residents with different education levels, disease situations, on-the-job situations, time, regions and sampling methods have differences in their satisfaction with the contract services of family doctors.
