Objective To investigate the whole genomic expression profiles of chronic atrophic gastritis with interleukin(IL)-1β-31CC/-511TT genotype as measured by oligonucleotide microarray technique.Methods Genomic RNA was extracted from gastric biopsies of 12 patients with chronic atrophic gastritis(6 with IL-1β-31CC/-511TT and 6 with IL-1β-31TT/-511CC).The genomic profiles of IL-1β gene polymorphisms 31CC/-511TT and 31TT/-511CC were compared and tested for differential expressed genes associated with 31CC/-511TT using Agilent human whole genomic oligonucleotide microarrays.The results were further analyzed in terms of gene ontology(GO).Results There were 200 differentially expressed genes associated with IL-1β-31CC/-511TT,159 of which were up-regulated and 41 were down-regulated.These genes mainly involved in macromolecule metabolic process,post-translational protein modification,ubiquitin cycle,and protein kinase cascade.Five genes had biological activities,one of which was down-regulated gene(PCSK5)and 4 were upregulated genes(PRKCA,NPLOC4,TRIB3 and MAPKAPK3).Conclusions The chronic atrophic gastritis with IL-1β-31CC/-511TT genotype has molecular phenotypes which is associated with malignance and inflammation.These individuals are needed more intensive preemptive treatment and dynamic surveillance.

A 76?year?old female patient complained of right chest pain for three months. CT scan showed a clump?like high?density shadow measuring 4.8 cm × 3.0 cm in size in the dorsal portion of the right lower lobe of the lung. Aspiration biopsy was performed, and biopsy samples were subjected to fungal culture and histopathological examination. Histopathological examination showed chronic granulomatous inflammation with hyaline septate hyphae. After 4?day culture, white villous dense colonies were formed on the Sabouraud′s agar medium. The center of the colonies was slightly elevated with wrinkles or radiating striae on the surface, and the bottom of the colonies was faint yellow in color. Microculture yielded abundant septate branched hyphae, and very few colorless hyaline quasi?circular spores. DNA sequencing of rDNA internal transcribed spacer (ITS) regions and β?tubulin genes was performed to identify the isolate, and antifungal susceptibility testing was carried out in vitro. The MEGA7.0 software was used to build phylogenetic trees of Aspergillus fumigatus complex and its closely related species. The isolate was identified as Aspergillus fumigatus by molecular biologic sequencing. The patient was diagnosed with pulmonary aspergilloma. After administration of itraconazole oral solution and vorionazole tablets, the condition got better obviously.

Objective:To evaluate the efficacy and safety of conbercept in patients with choroidal neovascularization secondary to chronic central serous chorioretinopathy (CSC-CNV).Methods:A retrospective case study was performed.The medical records of 13 patients (14 eyes) diagnosed as chronic CSC-CNV in Hangzhou Branch of Eye Hospital of Wenzhou Medical University from September 2015 to January 2018 were collected.All the study eyes received intravitreal injection of conbercept (0.05 ml/0.5 mg) under one intravitreal injection and pro re nata (PRN) treatment.The best corrected visual acuity (BCVA) and central macular thickness (CMT) before initial injection and 1 week, 1 month, 2, 3 and 6 months after initial injection were measured and analyzed.This study followed the Declaration of Helsinki and written informed consent was obtained from each patient before initial injection.The study protocol was approved by the Ethics Committee of Hangzhou Branch of Eye Hospital of Wenzhou Medical University (No.2019-029-K-28).Results:During the 6-month follow-up, the mean administration times was 1.93±0.83, and all the CNV secondary to CSC did not grow outside the retinal pigment epithelium layer.The BCVA values before initial injection and 1 week, 1 month, 2, 3 and 6 months after initial injection were 0.51±0.32, 0.43±0.34, 0.36±0.35, 0.31±0.28, 0.27±0.29 and 0.26±0.30, respectively, with a significant difference among different time points ( F=21.225, P<0.05). The BCVA values at each time point after initial injection were significantly better than that before initial injection (all at P<0.05). The CMT values before initial injection and 1 week and 1 month, 2, 3, 6 months after initial injection were (299.07±132.90), (216.50±70.94), (203.00±61.87), (234.29±95.70), (194.21±46.46) and (207.43±55.46) μm, respectively, and the difference was statistically significant among different time points ( F=3.768, P<0.05). The CMT values at each time point after initial injection were significantly better than that before initial injection (all at P<0.05). No severe treatment complications were observed during the follow-up period. Conclusions:Intravitreal injection of conbercept is safe and can effectively reduce the CMT and improve BCVA of chronic CSC-CNV patients in the short term.

Objective:To evaluate the effect of early mobilization on mortality in intensive care unit (ICU) patients with mechanical ventilation after discharge by Meta-analysis.Methods:Databases including SinoMed, China National Knowledge Infrastructure (CNKI), Wanfang data, PubMed, the Cochrane Library, Web of Science, and Embase were searched from inception to September 17th, 2020, to collect randomized controlled trials (RCT) about early mobilization on mortality of patients with mechanical ventilation in ICU after discharge, the references included in the literature were traced. The control group was given routine care, the experimental group was given early mobilization on the basis of the control group, including passive or active mobilization on the bed, sitting on the bed, standing by the bed, transferring to the bedside chair and assisting walking. The literature screening, data extracting, and the bias risk assessment of included studies were conducted independently by two reviewers. Stata 12.0 software was then used to perform Meta-analysis. Funnel plot was used to test publication bias.Results:A total of 10 RCT studies involving 1 323 patients were included, with 660 patients in the control group and 663 patients in the experimental group. The results of literature quality evaluation showed that 7 studies were grade A and 3 studies were grade B, indicating that the overall quality of included literatures was high. The Meta-analysis results showed that early mobilization did not increase the mortality of patients with mechanical ventilation in ICU after discharge [odds ratio ( OR) = 0.92, 95% confidence interval (95% CI) was 0.75-1.13, P = 0.449]. Subgroup analysis results showed that early mobilization had a tendency to reduce the mortality of ICU patients with mechanical ventilation at 3, 6 and 12 months after discharge, but the difference was not statistically significant (3-month mortality: OR = 1.02, 95% CI was 0.74-1.40, P = 0.927; 6-month mortality: OR = 0.95, 95% CI was 0.70-1.27, P = 0.712; 12-month mortality: OR = 0.60, 95% CI was 0.33-1.10, P = 0.101). Funnel plot showed that the distribution of included literatures was not completely symmetrical, suggesting that publication bias might exist. Conclusions:Early mobilization does not increase the mortality of ICU patients with mechanical ventilation after discharge. Although it tends to have a favorable outcome in reducing mortality, and has a trend to reduce the mortality. However, due to the small number of included literatures, small sample size and differences in the specific implementation of early mobilization among various studies, a large number of high-quality RCT studies are still needed for further verification.

OBJECTIVE To investigate the mecha-nism of endoplasmic reticulum stress in cerebral isch-emic stroke from a theoretical perspective based on net-work pharmacology.METHODS GeneCards and OMIM databases were used to screen out the related targets of cerebral ischemic stroke and endoplasmic reticulum stress.And Venny2.1.0 was used to draw Venn's diagram to get the intersecting genes between cerebral ischemic stroke and endoplasmic reticulum stress.String data-base was used to get the protein-protein interaction(PPI)diagram and cytoscape was used for visualization analy-sis.The key genes were screened out by cytohubba plug-in,and enrichment analysis was performed.RESULTS Network pharmacology showed that there were 3744 cerebral ischemic stroke-related targets and 8675 endo-plasmic reticulum stress-related targets.After screening,41 common targets were got.There were 37 nodes,390 edges in the PPI network,namely,there were 37 interact-ing proteins and 390 interacting relationships.The key genes identified by cytohubba plug-in were IL-6,ALB,INS,TNF,AKT1,CASP3,MAPK3,TP53,SIRT1 and VEGF.The biological process involves reaction to oxida-tive stress,the regulation of neuron death,and negative regulation of cell differentiation,etc.;cellular components were related to the membrane raft,smooth endoplasmic reticulum,endoplasmic reticulum lumen and other com-ponents;molecular function aspects were related to sig-naling receptor activator activity,chaperone binding and protease binding.Enrichment analysis of pathway revealed that the intersecting targets were involved in PI3K/Akt pathway and protein processing in endoplasmic reticulum,etc.CONCLUSION The endoplasmic reticu-lum stress in cerebral ischemic stroke is related to the bi-ological processes of reaction to oxidative stress,the reg-ulation of neuron death,and negative regulation of cell differentiation,the mechanism may be related to neuroin-flammation and apoptosis.

Objective:To evaluate the effect of preventing and treatment of pharmaceuticals on intensive care unit-acquired weakness (ICU-AW) by systematic review.Methods:The randomized controlled trials (RCTs) concerning pharmaceutical prevention and treatment about ICU-AW in SinoMed, CNKI, Wanfang data, PubMed, Cochrane Library, Web of Science, EMbase, and other sources were searched from their foundation to May 30th, 2019. The patients in the intervention group were treated with drugs to prevent or treat ICU-AW; and those in control group were treated with other rehabilitation methods. Data searching, extracting and quality evaluation were assessed by two reviewers independently. Stata 12.0 software was then used for Meta-analysis. Only descriptive analysis was conducted when only one study was enrolled.Results:A total of 11 RCTs were enrolled with 1 865 patients in the intervention group and 1 894 in the control group. The results of quality evaluation showed that 4 studies were A-level and 7 studies were B-level, indicating that the overall quality of the enrolled literature was high. Meta-analysis showed that intensive insulin therapy could prevent ICU-AW [relative risk ( RR) = 0.761, 95% confidence interval (95% CI) was 0.662-0.876, P = 0.000], but reduced phenylalanine loss (nmol·100 mL -1·min -1: -3±3 vs. -11±3, P < 0.05) and glutamine intake (nmol·100 mL -1·min -1: -97±22 vs. -51±13, P < 0.05). There was no significant difference in the prevention and treatment of ICU-AW between other drugs (including growth hormone, glutamine, dexmedetomidine, neostigmine, oxandrolone, and intravenous immunoglobulin) and control group. Conclusions:Intensive insulin therapy can prevent ICU-AW, but the risk of hypoglycemia will increase. Other drugs including growth hormone, glutamine, dexmedetomidine, neostigmine, oxandrolone, and intravenous immunoglobulin have no obvious advantages in the prevention and treatment of ICU-AW, so no drug has been recommended to prevent and treat ICU-AW.

Objective To compared the macular blood flow parameters among myopic choroidal neovascularization (mCNV), high myopia (HM) and normal subjects.Methods Retrospective study. Forty patients (40 eyes) diagnosed as mCNV (mCNV group) in the Eye Hospital of Wenzhou Medical University at Hangzhou from June 2016 to November 2018, age-matched, sex-matched and diopter-matched 40 HM patients (40 eyes, HM group), age-matched and sex-matched 40 healthy persons (40 eyes, normal group) were enrolled in this study. Retina superficial and deep vessel density, the area of foveal avascular zone (FAZ), a-circularity index (AI) and vessel density around the 300 μm width of the FAZ region (FD) on macular 3 mm×3 mm scan on OCTA of 3 groups were compared.Results There were significant differences in the average retina superficial, deep vessel density, the area of FAZ, AI and FD among 3 groups (F=24.82, 9.18, 3.58, 7.68, 14.15;P<0.05). The average retina superficial and deep vessel density and FD in mCNV group were lower than those in HM group (P<0.05). The average retina superficial and deep vessel density and FD in HM group were lower than those in control group (P<0.05). The average area of FAZ in mCNV group was smaller than that in control group (P<0.05). The average AI in mCNV group was less than that in the other 2 groups (P<0.05). Conclusions The retina superficial, deep vessel density and FD decreased, the area and the form of FAZ remained unchanged in HM subjects comparing with normal subjects. While retina superficial, deep vessel density and FD decreased more, the area of FAZ reduced, the form of FAZ tend to be irregular in mCNV.

Objective:To observe the clinical efficacy of half-dose photodynamic therapy (PDT) in the treatment of acute central serous chorioretinopathy (CSC) by enhanced deep imaging-OCT (EDI-OCT).Methods:A retrospective case study. From September 2015 to November 2018, 100 patients with acute CSC who received half-dose PDT in Hangzhou Branch of the Eye Optometry Hospital of Wenzhou Medical University were included in the study. Among 100 patients, 69 patients were males and 31 patients were females; the average age was 49.63±7.97 years; the average duration of disease was 2.19±0.71 months. All patients underwent BCVA, EDI-OCT, FFA, ICGA and other examinations. BCVA was used on the international standard visual acuity chart and converted to logMAR visual acuity records. Before treatment, the average logMAR BCVA was 0.29±0.19, the average macular foveal retinal thickness (CMT) was 370.59±134.98 μm, and the average macular subfoveal choroidal thickness (SFCT) was 366.93±86.95 μm. All patients were treated with half-dose PDT. We compared the changes of BCVA, CMT, SFCT, and subretinal fluid (SRF) of the eye before treatment and 2 weeks after treatment and 1, 3, and 6 months. Pearson correlation analysis method was used to analyze the correlation between BCVA and baseline BCVA, CMT, SFCT after 6 months of treatment.Results:Six months after treatment, SRF was completely absorbed in 98 eyes, with an effective rate of 98.0%. Compared with before treatment, 2 weeks and 1, 3, and 6 months after treatment, the BCVA of the eye significantly increased ( F=66.493, P<0.001), and CMT and SFCT significantly decreased ( F=134.625, 30.394; P<0.001,<0.001). The results of Pearson correlation analysis showed that BCVA was positively correlated with baseline BCVA 6 months after treatment ( r=0.529, P<0.001), and there was no significant correlation with CMT and SFCT. There were no serious complications related to treatment during the follow-up period. Conclusions:Half-dose PDT can effectively increase BCVA in a short period of time for acute CSC. EDI-OCT can observe that CMT, SFCT and SRF absorption are significantly reduced after treatment.

Objective: To explore the effects of exercise rehabilitation on the depression and anxiety state and quality of life in patients with chronic heart failure. Methods: 400 cases of chronic heart failure patients were selected as the research objects.They were randomly divided into control group(n=200)and exercise rehabilitation group(n=200) by random number table.Two groups were given symptomatic treatment and routine care on a regular basis, and exercise rehabilitation group again on this foundation to give rehabilitation therapy for 3 weeks.Self-rating anxiety scale(SAS) and Self-rating depression scale(SDS)were used to score the anxiety and depression of the two groups before and after rehabilitation.The SF-36 was used to assess the quality of life of patients.Rehabilitation satisfaction questionnaire was used to investigate the satisfaction degree of rehabilitation. Results: There was no significant difference in SAS and SDS scores between the two groups before intervention (P>0.05). After intervention, the SAS and SDS scores of the two groups were significantly lower than those before intervention (P<0.05). SAS and SDS scores in exercise rehabilitation group ((27.47±4.82)vs(45.63±5.61))were significantly lower than those in control group ((43.17±4.81) vs (59.61±4.18))(P<0.05). Before intervention, there was no significant difference in the scores of SF-36 scale between the two groups (P>0.05). After intervention, the scores of SF-36 scale were significantly increased in the two groups, and the difference was statistically significant compared with that before intervention (P<0.05). All the factors of SF-36 in exercise rehabilitation group were significantly higher than those in control group (mental health: (72.06±7.48)vs(64.34±7.01), emotional function: (81.06±7.01)vs(76.05±6.92), social function: (81.14±7.83)vs(71.26±7.65), overall health: (70.14±8.05)vs(61.26±7.95), energy: (74.56±7.81)vs(69.46±7.40), the body pain: (68.51±7.36)vs(60.26±7.51), physical limitations: (64.99±7.31)vs(59.62±7.53 ), physiological function: (69.71±7.63)vs(63.84±7.04), all P<0.05). The satisfaction of the exercise rehabilitation group (92.5%)was significantly higher than that of the control group(75.0%) (P<0.05). Conclusion Exercise rehabilitation training can not only improve the anxiety and depression of patients with chronic heart failure, but also effectively improve the quality of life of patients.Exercise rehabilitation training has a high degree of recognition, and is worthy of extensive application in clinical practice.
