Objective To provide basis to improve the ability of primary care services in Chengdu by comparatively analyzing inpatient medical service of primary medical institutions (community health service centers and township health centers). Methods From October to November 2016, the data of inpatient services in primary medical institutions in Chengdu, including 390 primary medical institutions in 22 districts (cities) and counties, were investigated by questionnaire. SPSS 19.0 was used for data collection and analysis, while the univariate logistic regression and multiple logistic regression were used to analyze the influencing factors. Results It was more common for rural primary medical institutions to carry out inpatient medical services than urban (96.18% vs. 53.84%). The coverage rate of insurance in urban areas was higher than rural areas (98.41% vs. 90.87%), while the rate of adopting clinical pathway of single disease was quite low both in urban areas (23.81%) and rural areas (18.25%). Primary medical institutions in urban areas launched more special projects of inpatient services than those in rural areas (14.29%–17.46% vs. 3.57%–7.54%). The total amount of inpatient medical services in 2015 in rural areas was larger than urban areas (529 611 vs. 103 912), the total number of inpatient services in rural was 5.09 times that in urban primary medical institutions, the average inpatient services in 2015 per one rural primary medical institution was 1.27 times that in urban, per 10 000 residents in rural areas consumed 3.01 times more inpatient medical services than those in urban areas in average, the median beds utilization efficiency in rural areas was better than in urban areas (74.47% vs. 22.47%); work intensity of inpatient medical service in rural areas was greater than in urban areas (234.57 vs. 81.74 cases per year per doctor). The number of inpatient services was positively related to population in service (when less than 100 000 residents), inpatient beds, the number of drugs, the number of medical staff. Conclusions For inpatient medical service, there are obvious differences between urban and rural areas in Chengdu. Therefore, above differences should be taken into full consideration in the allocation of resources in primary medical institutions. Thus more targeted management measures should be formulated.
ObjectivesTo systematically review the value of cross-linked carboxy-terminal telopeptide of type I collagen (ICTP) in the diagnosis of bone metastases of lung cancer.MethodsThe Cochrane Library, PubMed, EMbase, WanFang Data and CBM databases were electronically searched to collect studies on ICTP in the diagnosis of lung cancer bone metastases from inception to November 2017. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies by QUADAS-2 standard. Meta-analysis was performed by using Meta-Disc 1.4 software.ResultsA total of 8 studies involving 781 patients were included. The results of meta-analysis showed that the pooled sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, diagnosis odds ratio and area under the curve of summary receiver operating characteristics were 71% (95%CI 0.65 to 0.76), 80% (95%CI 0.76 to 0.84), 3.79 (95%CI 2.31 to 6.21), 0.35 (95%CI 0.25 to 0.49), 14.67 (95%CI 6.99 to 30.81) and 0.860 3, respectively.ConclusionsICTP cooperate with imaging tests may be accurate and practical in diagnosis of bone metastases of lung cancer. Due to the limited quality and quantity of included studies, the above results should be validated by more studies.
ObjectiveTo explore the preoperative evaluation result of multidetector computed tomography (MDCT) in aortic stenosis (AS) patients with bicuspid aortic valve (BAV) undergoing transcatheter aortic valve replacement (TAVR) in order to summarize relevant experience.MethodsA total of 33 consecutive AS patients who underwent TAVR in Department of Cardiology, First Affiliated Hospital of Xinjiang Medical University from March 2016 to June 2020 were enrolled, and the preoperative evaluation characteristics of MDCT were compared between tricuspid aortic valve (TAV) and BAV.ResultsIn the 33 patients, whose mean age was (74±6) years, 22 were male and 11 were female, 17 were with BAV and 16 were with TAV. The medium (lower quartile, upper quartile) of calcification score was 360 (192, 1 034) mm3. There were 12 cases of artificial valve model to be speculated Downsize, including 9 calcific BAV cases (75%).ConclusionThe calcific BAV has a higher ratio of Downsize in the TAVR procedure.
Stroke is one feared complication after transcatheter aortic valve replacement (TAVR). It affects the prognosis of TAVR, leading to a decline in the survival rate and quality of life of patients, while increasing the economic burden of patients. In recent years, a variety of cerebral embolic protection devices have been used to reduce the incidence of stroke during TAVR and improve the prognosis, some of which have been approved for clinical use. However, there are many controversies about their safety and effectiveness. This article reviews the definitions, short-term and long-term incidences, and risk factors of TAVR-related stroke, and elaborates on recent large-scale studies of different cerebral embolic protection devices.
Severe symptomatic native aortic regurgitation (AR) is associated with poor prognosis. Surgical aortic valve replacement is presently the main choice of treatment according to current guidelines. The data of safety and efficacy of transcatheter aortic valve replacement (TAVR) for patients with pure native AR were limited. In this paper, a case of AR patient with heart failure was reported. After preoperative CT evaluation and operation plan, the postoperative symptoms improved significantly. Bundle branch block and retroperitoneal hematoma appeared during hospitalization. After the treatment, the patient’s condition improved. Before the discharge, cardiac ultrasound indicated that the reflux was significantly improved, no perivalvular leakage was observed, and cardiac function was improved. AR remains a challenging pathology for TAVR. TAVR is a feasible and reasonable option for carefully selected patients with pure AR.
It has been 20 years since the first transcatheter aortic valve replacement (TAVR) was performed internationally in 2002, and the development of TAVR technology in China has also been more than 10 years. The reliability of TAVR has been clinically proven, and it has also brought good benefits to patients with aortic stenosis. With the gradual progress of technology, TAVR has a trend to surpass surgical aortic valve replacement and become the mainstream surgery for patients with aortic stenosis. This article will review the relevant issues in the development of TAVR technology in recent years, based on existing research, and provide certain clinical references for the future development of TAVR technology.
Objective To investigate the use of oral anti-diabetic drugs and sugar blood control situation in advanced aged patient with diabetic mellitus in a community health centre in order to provide references for rational drug use. Methods A cross-sectional survey about oral anti-diabetic drugs was carried out in senile diabetic patients who visited the community health centre and established complete health documents voluntarily from February 2012 to February 2013. Results There were 176 cases of advanced aged patients with type 2 diabetic mellitus, of which, 107 cases were female and 69 cases were male, whose age ranged from 80 to 94. Among 176 cases, there were 107 (60.80%) patients with type 2 diabetic mellitus combined with hypertension, chronic heart diseases, and stoke; 155 had oral anti-diabetic drugs (88.06%). 67.19% of patients who took one oral anti-diabetic drug chose α-glycosidase inhibitors, followed by sulfonylurea. 53.73% of patients who received combination therapy chose glycosidase inhibitors and sulfonylurea. For the treatment of anti-diabetic drugs, 73.68% of patients met the criteria (fasting blood sugar: no more than 8.0 mmol/L), with control rates of 73.56% for α-glycosidase inhibitors and 72.58% for sulfonylurea. More than half of the patients could not be evaluated for their glycosylated hemoglobin levels were not tested. Conclusion Doctors working in community health centres should choose oral anti-diabetic drugs according to patients’ own conditions when treating advanced aged patients with diabetic mellitus in order to avoid adverse reaction such as hypoglycemia. Glycosidase inhibitors are the mostly used drug in the community health centre because it is safe with less adverse reaction when used in senile people and it could ideally control their blood sugara.
ObjectiveTo investigate the regulatory effect of miRNA-21-5p (miR-21) on spinal fibroblasts, and to explore the mechanism of miR-21 related pathological process of spinal cord injury.MethodsSpinal cord fibroblasts were identified by immunofluorescence. Spinal fibroblasts damage model was established by scratch method. Quantitative real-time polymerase chain reaction (RT-PCR) was used to determine the relative expression of miR-21 and fibrosis-related genes in spinal cord fibroblasts after injury. The expression of miR-21 in spinal cord fibroblasts was up-regulated and down-regulated by using miR-21 mimics/inhibitor, and the expression levels of apoptosis and proliferation-related proteins were detected by Western Blot (WB).ResultsThe expression of miR-21 and fibrosis-related genes were increased after spinal cord fibroblast scratch (P<0.05). Up-regulation of the miR-21 can increase the expression of apoptosis-related genes in fibroblasts (P<0.05), and vice versa. The proliferation of fibroblasts was consistent with the expression of miR-21, while the apoptosis of fibroblasts was contrary to the expression of miR-21.ConclusionsmiR-21 enhanced the fibrosis and proliferation, inhibited the apoptosis of spinal cord fibroblasts after mechanical injury. This indicates that miR-21 is closely related with the formation of fibrotic scar after spinal cord injury, which also providesa potential therapeutic target for spinal cord injury.
Objective To summarize the current management of anterior cruciate ligament (ACL) injury in children and adolescents, in order to provide reference for the management of ACL injury in children and adolescents. MethodsThe relevant literature at home and abroad in recent years was extensively accessed to summarize the management status of ACL injury in children and adolescent. Results The number of ACL injury in children and adolescents is increasing every year. The diagnosis of ACL mainly depends on symptoms and signs. Rehabilitation, physeal-sparing techniques, partial transphyseal techniques, all-epiphyseal techniques, and transphyseal techniques are used to treat ACL injury in children and adolescents. Conclusion Dynamic monitoring of knee joint in children and adolescents should be strengthened. The best treatment for ACL injury in children and adolescents is selected according to the patients’ actual age, bone age, Tanner stage, and physiological conditions such as menstruation, body growth speed, and other characteristics.
