Presbyopia is a physiological phenomenon related to age, in which there is a progressive difficulty in near vision due to decreased accommodation ability. It is one of the main reasons for the decline in visual related quality of life of people over 40 years old. The therapeutic objective is to improve symptoms, enhance functional near vision, and achieve the goal of restoring self-accommodation. A multitude of correction strategies are available, conventional spectacles is the simplest and safest method, which including monofocal, bifocal, trifocal, or gradient multifocal glasses. With the increasing demand for visual quality, corneal contact lenses and presbyopia correction surgeries(corneal refractive surgery, intraocular surgery, and scleral surgery)are becoming more and more accepted. The goal of these surgeries is to correct existing refractive errors while properly addressing the issue of decreased accommodation ability. At the same time, research on pharmacological interventions for presbyopia has been increasing year by year, including miotics and lens softeners, to improve the symptoms of presbyopia through different mechanisms. This article provides a review of relevant literature on presbyopia correction in recent years.

Background::Limited information exists regarding the impact of severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) infection on psoriasis patients. The objective of this study was to identify clinical factors associated with the prognosis of psoriasis following SARS-CoV-2 infection.Methods::A retrospective, multicenter study was conducted between March and May 2023. Univariable and multivariable logistic regression analyses were employed to identify factors associated with coronavirus disease 2019 (COVID-19)-related psoriasis outcomes. The study included 2371 psoriasis patients from 12 clinical centers, with 2049 of them having been infected with SARS-CoV-2.Results::Among the infected groups, lower exacerbation rates were observed in individuals treated with biologics compared to those receiving traditional systemic or nonsystemic treatments (22.3% [236/1058] vs. 39.8% [92/231] vs. 37.5% [140/373], P <0.001). Psoriasis progression with lesions (adjusted odds ratio [OR] = 8.197, 95% confidence interval [95% CI] = 5.685–11.820, compared to no lesions), hypertension (adjusted OR = 1.582, 95% CI = 1.068–2.343), traditional systemic (adjusted OR = 1.887, 95% CI= 1.263–2.818), and nonsystemic treatment (adjusted OR= 1.602, 95% CI= 1.117–2.297) were found to be associated with exacerbation of psoriasis after SARS-CoV-2 infection, but not biologics (adjusted OR = 0.931, 95% CI = 0.680–1.274, compared to no treatment), according to multivariable logistic regression analysis. Conclusions::A reduced risk of psoriasis exacerbation after SARS-CoV-2 infection was observed with biologics compared to traditional systemic and nonsystemic treatments. Significant risk factors for exacerbation after infection were identified as existing psoriatic lesions and hypertension.

The emergence of high virulent mutant strains of infectious bursal disease virus(IBDV)becomes a serious threat to the poultry industry.However,the live attenuated IBDV vaccine can potentially revert to a virulent strain.Therefore,it is a necessary to develop safe and effective IB-DV-associated vaccines.The construction of a recombinant Marek's disease(MD)vaccine strain,CVI988,expressing the IBDV VP2 protein,can protect against disease induced by both IBDV and Marek's disease virus(MDV).Here,the IBDV-VP2 gene was integrated into the UL55 locus of CVI988 by bacterial artificial chromosome(BAC)technique,resulting in the recombinant virus CVI988 BAC-VP2.The recombinant virus was characterized by PCR,IFA and subsequently the bi-ological properties of the recombinant virus were investigated.The results showed that the recom-binant virus CVI988 BAC-VP2 was successfully rescued.The VP2 protein stably expressed in chick-en embryo fibroblasts(CEF).The growth kinetics and plague size assays showed that there was comparable replication ability between recombinant virus and parental virus.This study provides the basis for the development of a low-cost vaccine against both IBDV and MDV infections.

Objective:To investigate the safety, feasibility and accuracy of esophageal sponge cytology in esophageal carcinoma screening in high-incidence districts.Methods:Opportunistic screening for esophageal carcinoma was conducted on individuals aged 40-75 years with high-risk factors for esophageal carcinoma and visited out-patient clinic in Lianshui People's Hospital from May 2021 to June 2022. A new esophageal cell collector independently developed in China was used for esophageal sponge cytology sampling followed by cytopathological analysis. Atypical squamous cells or more severe lesions were defined as positive esophageal sponge cytology. Then gastroscopy was performed, and all suspicious areas under the endoscopy were biopsied for histopathological examination. Gastroscopy, biopsy histopathology and esophageal sponge cytology were conducted blindly in pairs. Outcome measures included adverse reactions during sampling, subject tolerability (using a visual simulation score), sampling quality, and diagnostic efficacy of esophageal sponge cytology using gastroscopy plus biopsy histopathology as the gold standard.Results:A total of 1 590 patients completed the screening program. During esophageal sponge cytology sampling, no serious adverse events were observed, and the adverse reactions were mainly manifested as vomiting during sampling [0.31% (5/1 590)] and sore throat after sampling [2.45% (39/1 590)], all of which resolved spontaneously without further medical intervention. The majority of subjects [98.62% (1 568/1 590)] reported good tolerance during the procedure. After sampling, 1 526 (95.97%) subjects had completely expanded sponge material, meeting the standard of good sampling quality. The scanning analysis of the digital pathology system showed that the number of sampled cells in 1 590 subjects ranged (2.01-4.00)×10 6, with a median of 3.48×10 6 cells, which could meet the requirements for interpreting cytological results. Using the positive esophageal sponge cytology for the diagnosis of esophageal carcinoma including high-grade intraepithelial neoplasia, esophageal squamous cell carcinoma and adenocarcinoma of esophagogastric junction, the sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were 98.57% (69/70), 91.51% (1 391/1 520), 34.85% (69/198), 99.93% (1 391/1 392), and 91.82% (1 460/1 590), respectively. Conclusion:Esophageal sponge cytology presents promising diagnostic efficacy for esophageal carcinoma screening, offering a simple, safe, convenient, and effective approach in high-incidence esophageal carcinoma regions.

Objective:To investigate the application of patient-based real-time quality control (PBRTQC) using exponentially weighted moving average (EWMA) method in internal quality control (IQC) procedures of thyroid function tests.Methods:The serum thyroid function test results of outpatients and inpatients in the Second Hospital of Shandong University from December 1, 2022 to April 30, 2023 were collected. Based on the PBRTQC professional intelligent software system, normality correction, parameter setting, program preparation and real-time operation of test data were carried out. The results of all patients who underwent thyroid function testing between May 1, 2023 and August 31, 2023 were used as the validation dataset. The estimated EWMA value of thyroid function test results and the cumulative coefficient of variation ( CV) over 4 months were calculated. The cumulative CV was compared with the criteria of precision quality standard (1/3TEa) and the CV of IQC. Westgard 2-2s and 1-3s rules were used for alarm setting. The early warning information of the EWMA quality control program were recorded and the potential causes of performance changes were analyzed. DxLab Mind software was used to conduct normal distribution statistics for all data, and the Kolmogorov-Smirnov test was performed on the test results. Results:The items related to serum thyroid function of the patients were all positively skewed. After data correction by Box-Cox method, the PBRTQC data of free triiodothyronine (FT3) and free thyroxine (FT4) were normally distributed, and their cumulative precisions ( CV) of EWMA within 4 months were 6.26% and 2.86%, respectively, both of which were lower than the precision quality target of 8.33%. However, the data of thyroid-stimulating hormone (TSH), thyroid peroxidase antibodies (TPOAb) and thyroglobulin antibody (TgAb) were still positive skewed after modification. The EWMA cumulative CV of TSH, TPOAb and TgAb were 13.16%, 15.31% and 16.77%, which were higher than the precision quality targets of 8.33%, 10% and 10%, respectively. The EWMA QC program can detect different out-of-control alarms, including FT4 false alarms due to sample source concentration and TSH result bias caused by changes in reagent performance. In addition, the EWMA QC program can also detect differences in FT3 results between different DXI800 fully automated chemiluminescence instrument instruments. Conclusions:The EWMA program based on PBRTQC professional intelligent software tools can monitor the patient data of the detection system in real time and continuously, dynamically identify and monitor the errors generated during the analysis process and give early warning. It can be used as a useful supplement for the daily IQC of thyroid function items, especially FT3 and FT4, and has good clinical application value.

Objective:The effect and safety of etoposide combined with G-CSF were compared with those of cyclophosphamide combined with G-CSF in autologous peripheral blood mobilization in patients with multiple myeloma (MM) .Methods:Patients with MM who received autologous peripheral blood stem cell mobilization and collection in the Department of Hematology, Beijing Chaoyang Hospital Affiliated to Capital Medical University from January 1, 2020 to July 31, 2023 were included. A total of 134 patients were screened by propensity score matching technology according to a 1∶1 ratio. A total of 67 cases were each treated with ETO combined with G-CSF mobilization scheme (ETO group) and CTX combined with G-CSF mobilization scheme (CTX group). Their clinical data were retrospectively analyzed.Results:①Collection results: the ETO and CTX groups [2 (1-3) d vs 2 (1-5) d; P<0.001] and CD34 + cells [7.62×10 6 (2.26×10 6-37.20×10 6) /kg vs 2.73×10 6 (0.53×10 6-9.85×10 6) /kg; P<0.001] were collected. The success rate of collection was 100.0% (67/67) versus 76.1% (51/67) ( P<0.001). Excellent rate of collection was 82.1% (55/67) versus 20.9% (14/67; P<0.001). Two patients in the ETO group switched protocols after 1 day of collection, and 11 patients in the CTX group switched protocols after 1-2 days of collection. ②Adverse reactions: granular deficiency with fever (21.5%[14/65] vs. 10.7%[6/56]; P=0.110), requiring platelet transfusion [10.7% (7/65) vs 1.8% (1/56) ; P=0.047]. ③Until the end of follow-up, 63 cases in the ETO group and 54 cases in the CTX group have undergone autologous transplantation. The median number of CD34 + cells infused in the two groups was 4.62×10 6 (2.14×10 6-19.89×10 6) /kg versus 2.62×10 6 (1.12×10 6-5.31×10 6) /kg ( P<0.001), neutrophil implantation time was 11 (9-14) d versus 11 (10-14) d ( P=0.049), and platelet implantation time was 11 (0-19) d vs. 12 (0-34) d ( P=0.035). One case in the CTX group experienced delayed platelet implantation. Conclusion:The mobilization scheme of etoposide combined with G-CSF requires relatively platelet transfusion, but the collection days are shortened. The collection success rate, excellent rate, and the number of CD34 + cells obtained are high, and the neutrophil and platelet engraftment is accelerated after transplantation.

Objective To investigate the relationship between circadian sleep-wake biorhythm and prognosis in patients with middle cerebral artery acute ischemic stroke.Methods A total of 71 patients with acute ischemic stroke of middle cerebral artery were selected as the case group,and 67 patients without acute ischemic stroke and cerebrovascular stenosis were selected as the control group.According to the modified Rankin score at discharge,patients with acute ischemic stroke were subdivided into the good prognosis group(53 cases)and the poor prognosis group(18 cases).General clinical data of patients were collected,and differences of circadian rhythm,daytime sleep-wake rhythm,nighttime sleep-wake rhythm and circadian sleep-wake rhythm indexes were analyzed and compared between the two groups.Multivariate Logistic stepwise regression analysis was used to analyze prognostic factors of acute ischemic stroke in middle cerebral artery.The receiver operating characteristic(ROC)curve was used to analyze the predictive value of relevant variables.Results Age,male ratio,hypertension,diabetes,hyperlipidemia,smoking and drinking history were significantly higher in the case group than those in the control group.Daytime stability(IS)in the case group was lower than that in the control group(P＜0.05).Daytime total sleep time,wake time after falling asleep,light sleep period,deep sleep period,non-rapid eye movement(NREM)sleep period,rapid eye movement(REM)sleep period and the proportion of deep sleep period,the proportion of REM sleep period were higher in the case group than those of the control group,while the REM sleep latency and the proportion of light sleep period were lower than those of the control group(P＜0.05).The total sleep time,wake time,light sleep period,NREM sleep period and REM sleep period were higher in the case group than those of control group,while the proportion of sleep latency and REM sleep period were lower than those of the control group(P＜0.05).The proportion of increased circadian sleep,increased daytime sleep and low sleep efficiency at night were higher in the case group than those of the control group(P＜0.05).Logistic stepwise regression analysis showed that daytime REM sleep was a prognistic factor in middle cerebral artery acute ischemic stroke.During daytime REM sleep,the area under ROC curve(AUC)was 0.705,the sensitivity was 0.811 and the specificity was 0.611.Conclusion After acute ischemic stroke of middle cerebral artery,the circadian sleep-wake rhythm is unbalanced,which is manifested as poor daytime stability,increased daytime sleep,increased circadian sleep and low sleep efficiency at night.Daytime REM sleep has predictive value for prognosis of acute ischemic stroke of middle cerebral artery.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Psoriasis is a chronic,recurrent,systemic inflammatory skin disease that is immune-media-ted.The balance and communication between the intestinal microbiota and its metabolites and the host play an important role in maintaining the body's normal functions,such as immune homeostasis and vitamin synthe-sis.Recent studies have found that compared with the healthy individuals,the psoriasis patients have experi-enced significant changes in the abundance and diversity of intestinal microbiota,including an imbalance in in-testinal microbiota,reduced production of short-chain fatty acids(SCFAs),and abnormal Firmicutes/Bacte-roidetes(F/B)ratio.The gut microbiota also changed after systematic medication treatment,biologic agents treatment and small molecule chemotherapy,indicating that the gut microbiota could be a potential biomarker for assessing treatment efficacy.The relationship between psoriasis and gut microbiota is not fully under-stood,and further research is needed.

Objective To investigate the effect of compassion focused therapy on cognitive function and sense of shame in stroke patients with hemiplegia.Methods A total of 100 stroke patients with hemiplegia admitted in our hospital were included as the research objects.The patients were randomly divided into a control group admitted from December 2020 to December 2021 and an observation group admitted from January 2022 to January 2023,with 50 patients per group.The patients in the control group received cognitive behavioural therapy,while those in the observation group received compassion focused therapy as well as cognitive behavioural therapy.The sense of shame,cognitive function,self-criticism and social anxiety in the two groups were observed and compared before and at the end of the intervention.Results The score of the sense of shame in the observation group was significantly lower than that in the control group(P<0.001).The cognitive function score in the observation group was lower than that in the control group at the end of intervention(P<0.05).and the score of the sense of shame scale in the observation group was lower than that in the control group at the end of the intervention(all P<0.05).Conclusion Compassion focused therapy can significantly reduce the self-criticism and sense of shame in the stroke patients with hemiplegia,and promote the recovery of the cognitive function.
