ABSTRACT
Objective To analyze the growth and development of children aged 6 to 14 years in Yangzhou City, Jiangsu Province, and to provide a basis for the evaluation of the growth and development and health care of local children. Methods In November 2020, a stratified cluster sampling method was used to investigate the physical development of 11 026 children aged 6 to 14 years in 9 primary and middle schools in Yangzhou. The results were compared with the current national standards in China. Results The BMI levels of children of all ages from 6 to 14 years in Yangzhou were higher than the national levels (t=6.947~20.093, P＜0.01). The heights of boys and girls were relatively close at pre-school age (t=1.348, P=0.025). Boys were slightly taller than girls at the ages of 6 to 8 and 10 to 11 years. At the ages of 9 and 12, girls were slightly taller than boys. Adolescent boys were significantly taller than girls. (t=15.161, P＜0.01). Conclusion In Yangzhou City, the height and weight development of students aged 6-14 years conform to the general growth and development trend, and their BMI is generally higher than the national average level.
ABSTRACT
Objective:This study was to explore "Internet + nursing service" mode, the tumor specialist nurses nursing service experience and feelings, in the process of mining "Internet + nursing service" model of current existing problems and future development direction, discussed under the background of constructing a new mode of medical and health services, how to expand the tumor specialized subject "Internet + nursing service" the breadth and depth to improve the quality of life of cancer patients and nursing service benefit.Methods:Through the review of the literature, the focus and direction of the research were determined. A semi-structured interview was conducted with 12 oncology nurses enrolled in "Internet + nursing service" by qualitative research. Colaizzi seven-step method was used to encode, classify and extract the data.Results:The experience of "Internet + nursing service" carried out by oncology nurses can be summarized into the following five themes: Be more willing; professional identity of specialist nurses is higher (self-identity, patient identity, social identity); Multiple psychological experience (stress experience: the limitation of specialized operation and the pressure of communication; Adaptive experience: "Specialist cooperation and two-person home visit mode" is well adapted). The time and economic cost of specialist services are higher. The matching degree of service item supply and market demand is insufficient.Conclusions:In order to further expand the depth and breadth of "Internet + nursing service" in oncology, and to benefit more cancer patients in the long-term treatment and rehabilitation process, it is necessary to improve the recognition degree of nurse specialty, so as to improve the willingness to work; increase nurse training to enhance nurses' comprehensive coping ability; improving policy and economic support based on the characteristics of tumor diseases; improve the oncology "Internet + nursing services" project.
ABSTRACT
Objective:To investigate the efficacy and safety of Xiatianwu eye drops in the treatment of pseudomyopia in children. Methods:A total of 8 000 children with pseudomyopia who received treatment in Jiaxing Hospital of Traditional Chinese Medicine between June 2018 and June 2019 were included in this study. They were randomly assigned to receive treatment with either raceanisodamine eye drops (control group, n = 4 000) or Xiatianwu eye drops combined with raceanisodamine eye drops (observation group, n = 4 000) for 30 successive days (1 treatment course). The uncorrected visual acuity and diopter in each group were detected by an 'E' chart and optometry. Axial eye length and intraocular pressure in each group were measured using an ophthalmic A/B ultrasound scanner and a non-contact tonometer to assess the therapeutic effects. The incidence of adverse reactions during the treatment period was calculated. Results:After 30 days of treatment, the uncorrected visual acuity in the observation group was significantly higher than that in the control group [(0.88 ± 0.33) vs. (0.81 ± 0.29), t = 10.077, P < 0.001]. The diopter in the observation group was significantly lower than that in the control group [(-0.99 ± 0.36) D vs. (-1.07 ± 0.39) D, t = 9.533, P < 0.001]. Total effective rate in the observation group was significantly higher than that in the control group (91.10% vs. 88.18%, χ2 = 18.422, P < 0.001). There were no significant differences in the axial eye length, intraocular pressure and the incidence of adverse reactions between the two groups (all P > 0.05). Conclusion:Xiatianwu eye drops combined with raceanisodamine eye drops in the treatment of pseudomyopia in children can improve uncorrected visual acuity, increase therapeutic effects, and does not increase the incidence of adverse reactions.
ABSTRACT
Objective:To observe and analyze the risk factors related to vitreous re-hemorrhage (PVH) after anti-VEGF drugs combined with vitrectomy (PPV) in patients with proliferative diabetic retinopathy (PDR).Methods:Retrospective analysis study. From April 2017 to July 2018, 100 eyes of 87 PDR patients who were diagnosed in Jiaxing Eye Hospital and received anti-VEGF drugs combined with 25G PPV were included in the study. Among them, there were 44 eyes in 38 males and 56 eyes in 49 females. The age ranged from 26 to 83 years, with an average age of 57.72±8.82 years. All patients were type 2 diabetes, with an average duration of diabetes 10.84±6.03 years. All affected eyes were assisted by the same doctor with a non-contact wide-angle lens under the standard three-channel 25G PPV of the flat part of the ciliary body. Five to 7 days before the operation, intravitreal injection of ranibizumab or conbercept 0.05 ml (10 mg/ml) was performed. The incidence of PVH was observed. The age of PVH patients, duration of diabetes, vision before operation, average fasting blood glucose and average postprandial blood glucose before operation, systolic blood pressure and diastolic blood pressure before surgery, laser treatment before surgery, lens removal during operation, intraocular filling during operation, retinal laser points during operation, and fundus lesions during operation (hyperplasia film, Retinal hemorrhage, vascular occlusion, proliferative retinal traction, retinal hiatus, retinal detachment, exudation, neovascularization) were analyzed to find out the cause of PVH. Spearman bivariate correlation analysis and binary logistic regression analysis were performed on the data.Results:Of the 100 eyes of 87 patients, PVH occurred in 17 eyes (17%). There were statistically significant differences in the number of eyes with vascular occlusion and proliferative traction during surgery in patients with and without PVH ( χ2=5.741, 8.103; P<0.05). There was no significant difference in age ( t=-1.364), duration of diabetes ( t=0.538), preoperative vision ( t=1.897), preoperative fasting blood glucose level ( t=1.938), preoperative postprandial blood glucose level ( t=1.508), preoperative systolic blood pressure ( t=-0.571), preoperative diastolic blood pressure ( t=0.275), whether received laser treatment ( χ2=2.678), the number of laser points during operation ( t=0.565), whether received lens removal during operation ( χ2=0.331), whether found new blood vessels during operation ( χ2=2.741) and whether received intraocular filling during operation ( χ2=0.060) between the patients with and without PVH ( P>0.05). Spearman's bivariate correlation analysis showed that patients with low vision, poor control of fasting blood glucose levels, vascular occlusion and proliferative retinal traction during the operation were related risk factors for PVH ( rs=0.208, 0.229, 0.240, 0.285; P<0.05). Binary logistic regression analysis showed that fundus vascular occlusion and hyperplastic retinal traction may be independent risk factors for PVH during surgery ( OR=5.175, 13.915; P<0.05). Conclusion:Fundus vascular occlusion and retinal traction caused by fibrovascular membrane hyperplasia in PPV may be independent risk factors for PVH in patients with PDR after anti-VEGF drugs combined with PPV.

ABSTRACT
Substantial evidence supports the neurodevelopmental hypothesis of schizophrenia. Meanwhile, progressive neurodegenerative processes have also been reported, leading to the hypothesis that neurodegeneration is a characteristic component in the neuropathology of schizophrenia. However, a major challenge for the neurodegenerative hypothesis is that antipsychotic drugs used by patients have profound impact on brain structures. To clarify this potential confounding factor, we measured the cortical thickness across the whole brain using high-resolution T1-weighted magnetic resonance imaging in 145 first-episode and treatment-naïve patients with schizophrenia and 147 healthy controls. The results showed that, in the patient group, the frontal, temporal, parietal, and cingulate gyri displayed a significant age-related reduction of cortical thickness. In the control group, age-related cortical thickness reduction was mostly located in the frontal, temporal, and cingulate gyri, albeit to a lesser extent. Importantly, relative to healthy controls, patients exhibited a significantly smaller age-related cortical thickness in the anterior cingulate, inferior temporal, and insular gyri in the right hemisphere. These results provide evidence supporting the existence of neurodegenerative processes in schizophrenia and suggest that these processes already occur in the early stage of the illness.

ABSTRACT
ObjectiveTo investigate the influencing factors of preoperative fearful anxiety,and explore the effect of nursing intervention for the improvement of preoperative fearful anxiety. Methods500 cases of surgical patients in our hospital from January 2009 to January 2010 were chosen as the research objects.They were randomly divided into the control group and the observation group with 250 patients in each group.The control group was given routine preoperative nursing care.The observation group was given preoperative nursing intervention.The general information,surgery program,knowledge of surgical program,the patients' family situation and economic situation were taken for statistics.Their SAS score 30 minutes before the surgery was determined,and the influencing factors of preoperative fearful anxiety were analyzed. ResultsThe study showed that the influencing factors of fearful anxiety included:character,education background,family economic status,knowledge of the situation of surgery and other factors.The anxiety score 30 min before surgery was compared,the observation group was significantly lower than that of the control group.The difference between the two groups was significant. ConclusionsThe preoperative fearful anxiety was directly related to patients' own situation and level of medical services.Fully understanding of the situation before surgery and targeted preoperative nursing interventions can effectively reduce preoperative anxiety,and is conducive to the successful implementation of operation and postoperative rehabilitation.
ABSTRACT
The aim of this study was to evaluate the safety and efficiency of a novel, oncolytic adenovirus mutant M1 administered in conjunction with immunosuppressive agents. Animal models were established by administering purified M1 either intravenously or retroperitoneally. At different time points, blood samples were taken from the mice for testing of liver and renal function. Microscopic examination of the liver was performed to observe pathological changes. Immunohistochemical analyses were used to evaluate the expression of the adenovirus in the liver. Lymphocyte recruitment to the liver and the activation of adenovirus specific T cells were also analyzed. No signs of general toxicity were observed, but transient increases in ALT and Scr were observed following the administration of M1. Microscopic examination revealed a mild inflammatory response in the liver. Compared to intravenous injection, higher expression levels of adenoviral proteins were observed after retroperitoneal injection. Combined treatment with cyclosporine A resolved the liver and kidney dysfunction and increased the concentration of the adenovirus in the liver. The use of the novel oncolytic adenovirus mutant M1 in vivo is safe, and the combined administration of M1 with immunosuppressive agents was able to enhance the effectiveness and safety profile of M1.
ABSTRACT
Herein we reported a case of follicular lymphoma with 50.26% clonal malignant lymphocytes and 50% tumor cells positive for the immunoglobulin heavy chain gene and B-cell lymphoma 2 gene (IGH-BCL2). To determine whether endothelial cells (ECs) within the tumor share the feature of advanced malignancy, we isolated and purified the ECs from the tumor by using the immunomagnetic beads conjugated with a monoclonal antibody against CD34, a surface marker of ECs. Thereafter, we identified ECs according to their morphology and found that ECs presented consistently flat and elongated appearance with a lot of Weibel-Palade bodies in the cytoplasm. Results of flow cytometry confirmed that ECs isolated from the follicular lymphoma expressed high level of both vWF and CD34 and the purity of the ECs fraction was more than 90%. Additionally, we used FISH to check chromosomal aberration in the purified ECs and found that some of the ECs had only one fusion signal for the green IGH probe and the red BCL2 probe in contrast to typical t(14;18)(q32;q21) translocation with two fusion signals. This phenomenon was also observed in the tumor cells. It might be a different breakpoint of IGH in this case, which induced the loss of the fusion signal, indicating t(14;18)(q32;q21) translocation. The positive cells accounted for 18% of the isolated ECs from the tumor, indicating that a proportion of ECs from follicular lymphoma had the same chromosome aberration as the neoplastic cells.
