Chronic disease is a major threat to human health. Fundus disease has become a major ophthalmic disease affecting daily life. Although great breakthroughs have been made in the treatment, compared with other chronic disease management, the management of patients with fundus disease is still in its infancy. To strengthen the management exploration of patients with fundus diseases, establish a management model of fundus diseases and strive to improve patients' awareness of fundus diseases and adherence to treatment and follow-up are the great challenges at present. All ophthalmic centers should strengthen patient education, establish a regional cooperation network, support the construction of grassroots medical capacity, cultivate talents, enhance training, promote the standardized treatment of fundus diseases, standardize fundus imaging inspection and diagnosis, and promote the homogeneous construction of diagnosis and treatment of chronic fundus diseases. We will accelerate the construction of a hierarchical diagnosis and treatment system and the ability to link consultation and referral. Through systematic management and intervention of fundus diseases, a large number of patients with fundus diseases will receive early screening, diagnosis, standardized continuous treatment and systematic management, and improve the quality of life of patients with fundus diseases.
The electroencephalogram (EEG) signal is a general reflection of the neurophysiological activity of the brain, which has the advantages of being safe, efficient, real-time and dynamic. With the development and advancement of machine learning research, automatic diagnosis of Alzheimer’s diseases based on deep learning is becoming a research hotspot. Started from feedforward neural networks, this paper compared and analysed the structural properties of neural network models such as recurrent neural networks, convolutional neural networks and deep belief networks and their performance in the diagnosis of Alzheimer’s disease. It also discussed the possible challenges and research trends of this research in the future, expecting to provide a valuable reference for the clinical application of neural networks in the EEG diagnosis of Alzheimer’s disease.
According to the requirements for the “three districts and two channels” in the sanitary industry standard Technique Standard for Isolation in Hospitals, combining with the spirit of current documents related to the prevention and control of coronavirus disease 2019, in order to guide medical institutions at all levels to conduct standardized design of fever clinics in accordance with the principle of “combining normal time and epidemic period”, this article explains the design points of the fever clinics for the prevention and control of coronavirus disease 2019, introduces the specific methods for the fever clinics to achieve “three districts and two channels”, draws a schematic diagram of the fever clinics in general hospitals, and explains the functional layout and medical procedures of the clean area, potential contaminated area, and contaminated area in detail; at the same time, a schematic diagram of the change of fever clinics from “normal” to “during the epidemic” is drawn, and the ideas for the conversion and the process after the conversion are introduced. It proposes design ideas and drawing references for the construction, transformation, and expansion of fever clinics.
Cardiogenic shock (CS) describes a physiological state of end-organ hypoperfusion characterized by reduced cardiac output in the presence of adequate intravascular volume. Mortality still remains exceptionally high. Veno-arterial extracorporeal membrane oxygenation (VA ECMO) has become the preferred device for short-term hemodynamic support in patients with CS. ECMO provides the highest cardiac output, complete cardiopulmonary support. In addition, the device has portable characteristics, more familiar to medical personnel. VA ECMO provides cardiopulmonary support for patients in profound CS as a bridge to myocardial recovery. This review provides an overview of VA ECMO in salvage of CS, emphasizing the indications, management and further direction.
ObjectiveTo analyze the clinical characteristics and epidemiological characteristics of patients with coronavirus disease 2019 treated early in Jiangxi province.MethodsFour-night patients with coronavirus disease 2019 treated in this hospital from January 21st to 27th, 2020 were included in this study. The epidemiological and clinical data of patients after admission were collected, and laboratory tests such as blood routine, urine routine, stool routine, liver and kidney function, electrolytes, myocardial enzymes, erythrocyte sedimentation (ESR), C-reactive protein (CRP), calcitonin, coagulation, T cell subset and Chest CT were reviewed. The clinical results of common and severe/critically ill patients were compared.ResultsOf the 49 patients, 40 were common and 9 were severe/critical. Fourty-six patients had a clear history of contact with Wuhan or other areas of Hubei. The sex ratio was 2.06∶1, and the average age was 42.9 years. The symptoms were mainly fever (78.7%), cough (38.8%), and fatigue (18.4%). 28.6% (14 cases) of patients had hypertension and diabetes. Serum lymphocyte count and calcium concentration of the patients were decreased, but lactate dehydrogenase, ESR, CRP and serum amyloid A were increased in these patients. T lymphocyte subsets (CD3+, CD4+, CD8+) decreased significantly in these patients. Forty-seven patients (95.9%) had single or scattered patchy ground glass density shadows on the chest CT. Compared with common patients, the patients with severe/critical patients were older (P=0.023), hospitalized later (P=0.002), and had higher comorbidities (P=0.017). ESR (P=0.001）, CRP (P=0.010) and the serum amyloid A (P=0.040) increased significantly, while CD3+ (P<0.001), CD4+ (P=0.012), CD8+ (P=0.006) decreased significantly in severe/critical patients.ConclusionsThe patients with coronavirus disease 2019 in Jiangxi province are commonly imported from Wuhan. Severe/critical patients are older, hospitalized later, and have more medical complications and more severe systemic inflammatory reactions than common patients.
ObjectivesTo systematically review the efficacy and safety of butylphthalide soft capsule with routine treatment for Alzheimer’s disease (AD).MethodsDatabases including CNKI, WanFang Data, VIP, CBM, PubMed, EMbase, and The Cochrane Library were electronically searched from September 2002 to July 2018 to collect randomized controlled trials of butylphthalide soft capsule with routine treatment for Alzheimer’s disease. The trial was screened based on inclusion and exclusion criteria, and the methodological quality of the included trial was assessed. Meta-analysis was then performed by Revman 5.3 software.ResultsA total of 8 studies involving 576 patients were included. The butylphthalide soft capsule group included 283 patients and the control group included 293 patients. The result of meta-analysis showed that butylphthalide soft capsule with routine treatment (Donepezil hydrochloride or Memantine or EGb761) significantly improved the score of mini-mental state examination (MMSE) (MD=3.19, 95% CI 2.69 to 3.69, P<0.001) and clinical efficacy (RR=1.36, 95%CI 1.21 to 1.53, P<0.001). There was no significant difference in number of adverse events between the butylphthalide group and the control group (RR=1.13, 95%CI 0.77 to 1.67, P=0.52).ConclusionsBased on the routine treatment, combining with butylphthalide soft capsule can further facilitate cognitive function of AD and improve clinical efficacy. At the same time, no increase in adverse reactions has been found. However, due to the low quality of the included studies, more high quality randomized controlled trials are required to verify the results.

Assembling medical aid teams (MATs) from the provinces outside Hubei was an important China-specific approach to dealing with public health emergencies during the coronavirus disease 2019 (COVID-19) pandemic in Hubei. In integrally taking over the COVID-19 intensive care wards in Wuhan, the Joint 7th and 8th Sichuan COVID-19 MATs applied the methods of modern hospital management to complete the medical task, concerning four key points as guidance by the Communist Party of China, system and regulation establishment, organization construction, and discipline persistence. This paper makes a theoretical summary on the basic management of the Joint 7th and 8th Sichuan COVID-19 MATs, and it is hoped that more COVID-19 MATs could summarize and share their successful management experiences in order to enrich and improve the management theory of MAT.
Since December 2019, severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection has gradually spread all over the world. With the implementation of class B infectious disease management policy for coronavirus disease 2019 (COVID-19), China has experienced a pandemic. For patients receiving a time-sensitive or emergency surgery, SARS-CoV-2 infection may increase the risk of postoperative pulmonary complications. An appropriate perioperative mechanical ventilation strategy, such as lung protective ventilation strategy, is particularly important for preventing postoperative pulmonary complications in patients undergoing general anesthesia. In addition, how to protect medical personnel from being infected is also the focus we need to pay attention to. This article will discuss the perioperative mechanical ventilation strategy for COVID-19 patients and the protection of medical personnel, in order to provide reference for the development of guidelines.
ObjectiveTo understand progress of stem cell transplantation in treatment of complex anal fistula.MethodThe relevant literatures were searched in the PubMed, Web of Science, CNKI, Wanfang, and other databases and the clinical efficacy, advantages and problems of the therapy were analyzed and summarized.ResultsThe stem cells currently used in the field of complex anal fistula were mainly the adipose tissue-derived stem cells, which had the biological characteristics of regenerative differentiation, immune regulation, and repair of intestinal mucosal barrier, which could be used as the seed cells for the treatment of complex anal fistula, its effectiveness was worthy of recognition. But its long-term clinical efficacy remained to be seen due to its clinical treatment options were different and lack of uniform standards. The safety of treatment for complex anal fistula was payed a attention because the stem cells had the oncogene activation and tumor suppressor gene inactivation characteristics.ConclusionsStem cell transplantation, as an emerging therapy, has broad prospects for patients with complex anal fistula that are difficult to solve by surgery, but its long-term efficacy is still unsatisfactory. Due to current sample size, short observation time, and lack of randomized control, current clinical data is not convincing, and high cost also limits its development of technology.
