Objective To evaluate the clinical value of ultrasonography guided percutaneous core needle biopsy in pancreatic lesions. Methods Thirty-four patients with 36 pancreatic lesions in Shanghai First People′s Hospital Afifliated to Shanghai Jiao Tong University from February 2012 to November 2013 underwent conventional ultrasound-guided percutaneous core needle biopsy using automatic gun and 18-gauge biopsy needles. The site, size, internal and surrounding vascularity, the sampling number of the lesions, and whether the specimens′ quality was satisfied were recorded. Then specimens were sent for pathological examination, and all above observations were compared with the ifnal diagnosis. Results The number of lesions with 2, 3 and 4 samplings was 32, 2 and 2, respectively. The average number of sampling was 2.2 (mean, 2.17;standard deviation, 0.51) and the acquisition rate of satisifed specimens was 89%(32/36). The pathological results of biopsy were malignant in 31 of 36 lesions including 27 cases of ductal adenocarcinoma, 2 cases of lymphoma, 1 case of small cell neuroendocrine carcinoma and 1 case of uterine leiomyosarcoma metastasis. The other 5 lesions were non-malignant including 3 cases of benign lesion, 1 cases of atypical hyperplasia and 1 cases of granulation tissue. The 36 lesions were ifnally diagnosed as 34 cases of pancreatic malignancy, 2 cases of non-malignant neoplasm. The sensitivity, speciifcity, accuracy, positive predictive value and negative predictive value of ultrasonography guided percutaneous core needle biopsy in pancreatic lesions were 91%(31/34), 100%(2/2), 92%(33/36), 100%(31/31) and 40%(2/5), respectively. Youden index was 0.91. Two patients had mild upper abdominal pain and 1 patient had transient elevated serum amylase. No pancreatitis, pancreatic fistula, peritonitis, bleeding or dispersion of malignant cells along the penetrating channel or other serious complications occurred. Conclusion Ultrasonography guided percutaneous core needle biopsy is a simple, rapid, safe and effective diagnostic method in pancreatic lesions with high clinical value.

Emergency transport of critically ill neonates is an important means to reduce neonatal mortality and improve prognosis.Neonatal transport score is used to evaluate the safety of transport, mainly including transport risk index of physiologic stability, mortality index for neonatal transportation, transport related mortality score and intrauterine transport score.Evaluating the severity of disease of critically ill newborns before, during and after transport can reduce the occurrence of transport complications, reduce neonatal mortality, improve prognosis and increase the success rate of treatment.This paper reviews the research progress of critical neonatal transport scoring at home and abroad to help clinicians choose appropriate scoring methods according to specific conditions, in order to provide a basis for continuous quality improvement in this field.

The "golden hour" strategy is an important measure to improve the short-term and long-term prognosis of neonates.It refers to optimizing interventions within one hour after birth, including neonatal resuscitation, transportation and early active treatment measures.Preterm birth and its complications are one of the main causes of neonatal death.Studies about "golden hour" strategy in premature infants have confirmed that it can increase the early stability, reduce complications and improve prognosis of preterm infants.This article reviews recent progress of "golden hour" in preterm infants and provide more information about quality improvement in premature infants care.

Objective:To develop a fully automatic detection system based on the deep convolution neural network (DCNN) for screening myopic maculopathy (MMD) and identifying its severity.Methods:Six thousand and sixty-eight fundus images were collected from Anhui No.2 Provincial People's Hospital to construct the training set, and the public fundus images data set was selected to construct the test set.The fundus images were preprocessed and amplified, and the grade of MMD lesions was labeled and the data was cleaned.The automatic MMD detection system proposed was composed of two-level network.The first level network structure was used to identify the presence of MMD, and the second level network structure was used to diagnose the severity of MMD lesions.The accuracy, specificity, sensitivity, precision, F1 value, area under curve (AUC) and Kappa coefficient of four commonly used DCNN network methods, VGG-16, ResNet50, Inception-V3 and Densenet, in MMD screening and severity recognition tasks were compared and analyzed.The study protocol adhered to the Declaration of Helsinki and was approved by a Medical Ethics Committee of Anhui No.2 Provincial People's Hospital ([L]2019-013).Results:The performance of Densenet network model was the best in the MMD screening task, with the sensitivity, specificity, accuracy, F1 value and AUC of 0.898, 0.918, 0.919, 0.908 and 0.962, respectively.The Inception-v3 network model was the best in MMD severity recognition task, with sensitivity, specificity, accuracy, F1 value and AUC of 0.839, 0.952, 0.952, 0.892, and 0.965, respectively.The visualization results showed that the network structure model used in this study could automatically learn the clinical characteristics of MMD severity, and accurately identify diffuse and focal chorioretinal atrophy areas.Conclusions:The MMD screening method using fundus images based on DCNN can automatically extract the effective features of MMD, and accurately screen MMD and judge its severity, which can provide effective assistance in clinical practice.

This is a follow-up study in two patients who were diagnosed with the occult ectopic adrenocorticotropin syndrome ( EAS) and treated with mifepristone in our hospital. The efficacy and adverse reactions of mifepristone in these two patients with EAS were investigated. The patients had significant improvement in clinical manifestations, the plasma adrenocorticotropic hormone ( ACTH) and cortisol levels decreased in patient 1, while patient 2 remained stable during the treatment. Patient 1 with diabetes mellitus stopped hypoglycemic agents, while the dose of antihypertensive drugs decreased in patient 2 with hypertension, and she was treated with surgery and suffered from transient adrenocortical insufficiency after surgical excision of the lesion. Mifepristone is effective and safe in treating EAS. Surgical treatment should be performed once the lesion is found during the follow-up.

Objective:To investigate the adhesion of polydopamine-modified collagen membrane composites to cartilage tissues and the effect on chondrocyte proliferation, and further explore the possibility of their application in autologous chondrocyte transplantation.Methods:Porous collagen membranes were prepared, and the polydopamine-modified collagen membrane composites were constructed by the adsorption method. The physical and chemical properties and structural characteristics of the membranes, such as thermal stability, thermal properties, porous structure, and surface element composition, were characterized by infrared spectroscopy, thermogravimetric analysis, differential thermal analysis, scanning electron microscopy, and X-ray photoelectron spectroscopy, respectively. The adhesion between the polydopamine-modified collagen membrane and fresh cartilage tissue was tested by a mechanical testing machine. The effects of the membranes on the adhesion and proliferation of rabbit chondrocytes were investigated by in vitro cell culture.Results:The structure and surface element composition of the membranes altered with the increase in the adsorption time of polydopamine, and the capacity of polydopamine increased with the increase in the adsorption time. The thermal stability and thermal properties of collagen membrane materials were not significantly affected by the adsorption of polydopamine. The adhesion of the membrane to cartilage tissue increased with the increase in the amount of absorbed polydopamine. The membranes showed a time-dependent promoting effect on the proliferation of the chondrocytes.Conclusions:The polydopamine-modified collagen membrane has potential application in articular cartilage repair, but more research is required to optimize the membrane before it is used in articular cartilage repair.

Restless legs syndrome (RLS) and ischemic cerebrovascular disease (ICVD) are two common disorders in neurology departments that place a significant economic burden on patients′ families and society. In recent years, increasing attention has been paid to the relationship between the two, but there is no clear-cut conclusion that RLS may be both a consequence of ICVD and associated with an increased risk of developing ICVD and poor functional outcome. This article summarizes the latest research findings on ICVD and RLS in China and abroad, with a view to providing a better understanding of their interaction and pathophysiological mechanisms, as well as providing some references for the early prevention and treatment of ischemic cerebrovascular events and rehabilitation.

Objective To explore the effects evaluation of extended care after “one-day care” for delivery women with gestational diabetes mellitus ( GDM ) . Methods From May to September 2013 in Department of Gynaecology and Obstetrics Peking University First Hospital, a total of 354 GDM pregnant women participated “one-day care” and then they were divided into experimental group (171 cases) and control group (183 cases) according to whether attended the extended care. Using repeated variance analysis measurement, the fasting blood glucose and postprandial 2h blood glucose values were compared whether the values had statistical significance between two groups at different visit time. Results The uterine-incision rates were 48. 55%(83/171) and 49. 7%(91/183) in the experimental group and control group respectively, and the incidence of giant babies were 9. 4%(16/171) and 12. 0%(22/183) respectively in the experimental group and control group (P>0. 05). The time point of before visit, during visit and last visit in the experimental group, the fasting blood glucose and postprandial 2 h blood glucose were lower than that of the control group (P<0. 05). Conclusions “One-day care” for GDM can reduce the blood glucose level of GDM delivery women, but it has not significant effects on the control of gestation′s body weight and to decline the uterine-incision rate and incidence of giant babies.

Objective We report four cases of myelin oligodendrocyte glycoprotein(MOG)antibody-associated dis-ease(MOG-AD)with cortical encephalitis as the main manifestation.We analyse the clinical features and relevant ancil-lary tests,and review the literature in order to provide a reference basis for the proper clinical management of this disease.Methods The clinical manifestations,cerebrospinal fluid cytology,imaging,treatment and prognosis of four patients with MOG-AD with cortical encephalitis as the main manifestation,admitted to the Department of Neurology of the Affili-ated Hospital of Jining Medical University from October 2020 to February 2023,were retrospectively analyzed.The anti-MOG antibodies were detected by a cell-based assay(CBA).Results The four patients in this paper were aged 16-32 years and all presented with cortical encephalitis.Three of them started with seizures and one presented with his first sei-zure 15 d after headache and fever.The cranial MRI showed thickening of brain tissue in the cortical area and multiple ab-normal signal shadows in the sulcal pools,with relatively high signal on FLAIR images.Serum anti-MOG antibody tests were positive.The patients were treated with hormones and/or immunoglobulin and discharged,with two patients experi-encing relapses.Conclusion MOG-AD can have a predominantly cortical encephalitis phenotype,presenting with head-ache,fever and seizures.The initial diagnosis is easily made as"infective meningoencephalitis or meningitis",and cra-nial MRI often shows unilateral or bilateral cortical swelling;immunotherapy is effective,but some patients may experi-ence recurrence;for patients with cortical encephalitis who are poorly treated with anti-infective therapy,the disease needs to be alerted,and a"positive"serum MOG-IgG test can clarify the diagnosis.
