Methods The clinico-pathological features, diagnosis and treatment methods of 21 cases of malignant breast lymphoma diagnosed between January 1980 and December 2007 were analyzed retrospectively and related domestic and overseas literature was reviewed. Results Among the 21 female patients, 18 had primary breast lymphoma (PBL), 3 had secondary breast lymphoma. All cases of PBL were non-Hodgkin’s lymphoma with mainly B cells as the origin. The median age of the patients was 46.5 years old. Most of the cases were diagnosed postoperatively and all patients were treated by operation combined with chemotherapy. Related literature reviewing showed that clinical staging and treatment modality were important factors of prognosis. Conclusion In treating malignant breast lymphoma, operation and chemoradiotherapy should be combined together to get a better result.
ObjectiveTo identify mutations in NDP, FZD4, LRP5, TSPAN12 in Chinese families with familial exudative vitreoretinopathy (FEVR) and observe the clinical features.MethodsRetrospective case series study. The 9 patients (18 eyes) and 5 normal members from 4 unrelated families were included in the study. The patients medical history and family history were collected in detail. All patients underwent best corrected visual acuity (BCVA), slit-lamp biomicroscopy, fundus colorized photography, fundus fluorescein angiography (FFA). Genomic DNA were collected from all the patients. Mutations were detected by directly sequencing to the whole coding region and exon-intron boundaries of NDP, FZD4, LRP5 and TSPAN12 gene. Polyphen and SIFT programs were used to predict the effects on the structure and functional properties of mutant protein.ResultsThere were two affected individuals in the family 2 carried LRP5 gene mutation [c.1330C＞T (p.R444C )] in exon 6 by sequence analysis. A score of 0.882 was acquired by Polyphen program analysis. And the missense change was predicted to be pathogenic by SIFT. Fundus changes of the proband showed angioplasia, tortuosity of peripheral vessels. And temporal dragging of the optic disc, peripheral avascular zone, neovascularization were found in FFA. Brush-like and straight of peripheral vessels were found in Ⅰ1. No variant was found in NDP, FZD4 and TSPAN12 gene.ConclusionOur study supports the gene mutation c.1330C＞T (p.R444C) of LRP5 is pathogenesis of FEVR. Patients with the same mutation could have variable phenotypic characteristics.
Objective To evaluate the diagnostic value of creatinine, as an indicator of glomerular filtration function injury. Methods MEDLINE, EMBASE and CBM-disc were searched from 1993 to 2003. Thirty four articles that described biomedical markers to indicate glomerular filtration function injury were selected according to specified inclusion criteria. These articles were evaluated systematically using SPSS, EXCEL, and RevMan software. Results The odds ratios of creatinine was 24.23. Areas under summarized receiver operator characteristic curve were 0.871. Selected articles were divided to groups for analysis according to diagnostic standards, such as inulin, iohexol, 125I-iothalamate, 51Cr-EDTA, 99mTc-DTPA and sodium thiosulfate. Inter-group analysis of creatinine was not statistically different (P=0.32). Intra-group analysis of inulin, 51Cr-EDTA, 99mTc-DTPA, and iohexol was not statistically different, P value were 0.61, 0.50, 0.36, 0.32, respectively. Intra-group analysis of 125I-iothalamate was statistically different (P=0.02). Selected articles were sub-grouped according to different analytic techniques of creatinine. Intra-group analysis by the Jaffe method was statistically different (P=0.03), intra-group analysis of enzymatic method was not statistically different (P=0.22). Conclusion The diagnostic value of creatinine was not qualified enough to indicate glomerular filtration function injury. Enzymatic methods are recommended to measure creatinine. Inulin or 51Cr-EDTA is suggusted to measure glomerular filtration rate in investigation of creatinine，and feedforward cohort is recommended to apply.
Objective To analyze the trends in the burden of intracerebral hemorrhage (ICH) and its related risk factors in China from 1990 to 2021, providing evidence for targeted prevention and control. Methods Based on public data from the Global Burden of Disease Study 2021, four epidemiological indicators, including incidence, prevalence, deaths, and disability-adjusted life-years (DALYs) were selected to describe the burden of ICH in China in 2021. Change rates and estimated annual percentage changes (EAPC) were calculated to evaluate the trends in disease burden from 1990 to 2021. The Das Gupta method was used to decompose the effects of population growth, population aging and epidemiological changes on the burden during this period. Finally, the attributable burden of risk factors related to ICH was analyzed. Results In 2021, the age-standardized incidence, prevalence, mortality, and DALY rates of ICH in China were 61.2/100000, 222.1/100000, 68.8/100000, and 1351.6/100000, respectively, all higher than global estimates. From 1990 to 2021, although these rates showed a declining trend (EAPC: ?2.24, ?1.26, ?2.38, and ?2.47, respectively), the absolute disease burden, including the absolute number of incidence cases, prevalence cases, deaths, and DALYs, continued to rise, with an increase ranging from 20.57% to 51.59%. In addition, the burden of ICH in China varied by age and sex, with older adults and males experiencing a higher burden. Decomposition analysis indicated that population aging and growth were the primary drivers of the increasing ICH burden in China, while epidemiological changes mitigated this trend. Metabolic factors were the predominant attributable risk factors for ICH. High systolic blood pressure, ambient particulate matter pollution, and diet high in sodium were important risk factors common to both genders. The DALY burden attributable to smoking and alcohol use was higher in men, whereas impaired kidney function and secondhand smoke had a greater impact on women. Conclusions The burden of ICH in China has continued to increase from 1990 to 2021, and it may further escalate in the context of population aging. Risk factor control remains a key priority for prevention. Future strategies should incorporate age- and sex-specific interventions to reduce the ICH burden in China.
Objective To use Kaiser model, three-dimensional risk matrix and Borda ordinal value method comprehensively to analyze the vulnerability of disasters, and identify the key prevention and control risks of the hospital. Methods From June to December 2020, a disaster vulnerability analysis was conducted on a tertiary hospital in southwest China. The risk event evaluation index system was established by referring to the Kaiser model, and the evaluation indexes were classified into three aspects: possibility, controllability and harmfulness. The three-dimensional risk matrix was used to calculate the risk score to determine the risk level. The Borda ordinal value was used to compare the ranking of risk events in the same risk level. Result “Violent medical injuries” “terrorist attacks” and “explosions” were the highest ranked risk events, which needed to be prioritized and targeted for improvement. Conclusions Disaster vulnerability analysis is an important means of emergency management in hospitals. Managers should dynamically assess hospital risks, take effective preventive measures for high-risk events, conduct emergency plan drills, continuously improve risk warning mechanisms, and enhance emergency management capabilities.
ObjectiveObservational studies have shown that plasma lipids are associated with the development of neurodegenerative diseases (NDD), but the causal relationship is unclear. This study investigated the causal relationship between 179 liposomes and NDD using a two-sample Mendelian randomization (MR). MethodsA two-sample MR method was used to comprehensively analyze the causal relationship between liposomes and major NDD such as Alzheimer's disease (AD), Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS) and multiple sclerosis (MS). The two sample software package and Phenoscanner database were used to screen for appropriate instrumental variables (TV). In this study, inverse variance weighting (IVW) was used as the primary measure of MR analysis, and various sensitivity tests were performed. ResultsMR-IVW results showed that phosphatidylethanolamine (PE) (OR=0.90, 95%CI 0.83 to 0.99, P=0.03), phosphatidylcholine (PC) (OR=0.92, 95%CI 0.85 to 0.99, P=0.02) and phosphatidylinositol (PI) (OR=0.90, 95%CI 0.83 to 0.99, P=0.03) were protective factors for AD. Sterol ester (OR=1.18, 95%CI 1.04 to 1.34, P=0.01) and cholesterol (OR=1.26, 95%CI 1.02 to 1.56, P=0.03) increased the risk of PD. PE (OR=0.79, 95%CI 0.64 to 0.98, P=0.03) and PC (OR=0.83, 95%CI 0.69 to 0.98, P=0.03) reduced the risk of PD. Diacylglycerol (DAG) (OR=1.24, 95%CI 1.01 to 1.54, P=0.04) and sphingomyelin (SM) (OR=1.13, 95%CI 1.08 to 1.58, P=0.01) were the risk factors for MS. PI (OR=0.77, 95%CI 0.62 to 0.95, P=0.02) and PC (OR=0.74, 95%CI 0.88 to 0.95, P=0.02) were protective factors for MS. PI (OR=1.02, 95%CI 1.01 to 1.04, P=0.02) and triglyceride (TG) (OR=1.03, 95%CI 1.01 to 1.05, P=0.02) increased the risk of ALS, PC (OR=0.98, 95%CI 0.97 to 0.99, P=0.03) decreased the risk of ALS. ConclusionThere is a causal relationship between sterol ester, cholesterol, PC, PE, PI, DAG, SM, TG and different NDD, which provides a theoretical basis and support for further clinical studies.
ObjectiveTo systematically review the efficacy and safety of transfemoral transcatheter aortic valve replacement (TFTAVR) under local anesthesia (LA) and general anesthesia (GA). MethodsElectronic databases including PubMed, EMbase, The Cochrane Library, Web of Science, CNKI, WanFang and CBM were searched to collect randomized controlled trial and cohort studies on clinical outcomes of TFTAVR under LA and GA from inception to September 2020. Two authors independently screened literature, extracted data and assessed the quality of studies, and a meta-analysis was performed by using Stata 16.0 software. ResultsA total of 30 studies involving 52 087 patients were included in this study. There were 18 719 patients in the LA group and 33 368 patients in the GA group. The results of meta-analysis showed that the in-hospital all-cause mortality rate [RR=0.65, 95%CI (0.45, 0.94), P=0.021], 30-day all-cause mortality rate [RR=0.73, 95%CI (0.62, 0.86), P＜0.001], 30-day stroke [RR=0.82, 95%CI (0.68, 0.98), P=0.025], cardiac arrest [RR=0.50, 95%CI (0.34, 0.73), P＜0.001], ICU stay time [RR=?6.86, 95%CI (?12.31, ?1.42), P=0.013], and total hospital stay time [RR=?2.02, 95%CI (?2.59, ?1.45), P＜0.001] in the LA group were all better than those in the GA group. There was no significant difference in the in-hospital stroke [RR=0.83, 95%CI (0.69, 1.00), P=0.053], in-hospital myocardial infarction (MI) [RR=1.74, 95%CI (0.43, 7.00), P=0.434], or 30-day MI [RR=0.77, 95%CI (0.42, 1.42), P=0.404] between the two groups. ConclusionLA provides a safe and effective way to induce sedation without intubation, and may be a good alternative to GA for TFTAVR.
Objective
To investigate the prevalence and related factors of diabetic retinopathy (DR) among residents with type 2 diabetes mellitus (T2DM) in Culai Town of Tai'an City in Shandong Province.
Methods
According to the DM management file database for community, 785 patients with T2DM were randomly selected by cluster sampling method. The questionnaires, routine general examinations, visual and fundus-free fluoroscopy were performed on all the patients. DR diagnosis and classification was according to the guidelines for clinical diagnosis and treatment of DR in China (2014). Both monocular and binocular DR were selected as DR patients, and the worse eye for binocular DR were treated as the DR classification of the patient. The patients were grouped by presence or absence of DR. GraphPad Prism 6, SigmaPlot 12.5, SPSS 20.0 and Excel were used to achieve data analysis. Also, SPSS 20.0 was used for multi-factor logistic regression analysis.
Results
A total of 699 patients (89.04%) were actually recorded. There were 122 eyes of 63 patients (9.01%) with DR (DR group), 1272 eyes of 636 patients (90.99%) without DR (NDR group). Among the 122 eyes of DR, there were 19 (15.57%), 17 (13.93%), 70 (57.38%), 10 (8.20%), 6 (4.92%) eyes in stage Ⅰ, Ⅱ, Ⅲ, Ⅳ, Ⅴ, respectively. The differences of mean age (t=15 290, P=0.002), DM duration (t=9075, P＜0.000) and diastolic blood pressure (t=15 810, P=0.006) between the two groups were statistically significant. There were 23 (36.51%) and 394 (61.95%) patients with hypertension history in the DR group and the NDR group, with the significant difference ( χ2=15.42, OR=0.35, 95%CI 0.21-0.60). There were 57 (90.48%) and 500 (78.62%) patients with fasting blood glucose larger than 6.11 mmol/L in the DR group and the NDR group, with the significant difference (OR=2.51, 95%CI 1.06-5.95, P=0.031). Logistic regression analysis showed that the age, fasting blood glucose and DM duration were influencing factors for DR (OR=1.039, 0.864, 0.898; P=0.021, ＜0.000, ＜0.000).
Conclusion
The prevalence of DR in patients with T2DM in Culai Town of Tai'an City is 9.01%. Age, DM duration, fasting blood glucose are associated to DR. Those with a history of hypertension may have a lower risk of DR than those without a history of hypertension.
Objective To evaluate the efficacy and safety of saxagliptin in type 2 diabetes patients. Methods The following databases as The Cochrane Library (Issue 2, 2011), PubMed (1978 to May 2011), EMbase (1974 to May 2011), CNKI (1978 to May 2011), VIP (1989 to May 2011) and CBM (1978 to May 2011) were searched. The quality of included randomized controlled trials (RCTs) was assessed according to the Cochrane Collaboration system review, and then meta-analysis was performed using RevMan 5.0. Results A total of 7 RCTs were included. The results of meta-analyses showed that HbA1c was significantly reduced in the saxagliptin group than that in placebo group (MD= –0.69, 95%CI –0.78 to –0.60, Plt;0.000 01). There was no significant difference in the incident rate of adverse reaction between two groups (RR=1.02, 95%CI 0.98 to 1.06, P=0.26). Conclusion Saxagliptin is effective and safe for type 2 diabetes. But its long-term efficacy and safety still need to be confirmed by performing more high quality, large sample RCTs with long-term follow-up.
