Effect of smart air cell mattress on sleep quality / 国际生物医学工程杂志

Objective:To investigate the effect of smart air cell mattresses on sleep quality.Methods:Twenty healthy young people were enrolled as subjects, and each subject underwent a four-night polysomnographic monitoring experiment, including two nights each on a smart air cell mattress and a general mattress. The differences in sleep quality were compared by self-assessment of sleep quality, objective sleep indicators, and electroencephalogram (EEG) spectral analysis.Results:In the comparison between the smart air cell mattress and the general mattress, the differences in self-assessment of sleep quality and objective sleep indicators were not statistically significant (all P > 0.05), but the smart air cell mattress had a slight overall advantage. The relative power of EEG in the low-frequency band and the relative power of EEG in the high-frequency band were higher in the subjects with the smart air cell mattress. Conclusions:For the healthy young population, the smart air cell mattress can positively influence sleep quality to some extent, and the change in EEG relative power indicates an increase in sleep depth.

Clinicopathological features of adult Wilms tumor with BRAF V600E mutation / 中华病理学杂志

Objective: To identify BRAF V600E mutations in adult Wilms tumor (WT) with overlapping histologic features of metanephric adenoma (MA) and to investigate the clinicopathological features of adult WT. Methods: The clinical features of adult WT diagnosed at the Fudan University Shanghai Cancer Center, Shanghai, China from 2012 to 2021 were reviewed. HE-stained slides of all cases were reviewed by 2 expert pathologists. Representative tissues were selected for BRAF V600E immunohistochemical (IHC) staining and gene sequencing. Results: In adult WT with MA-like areas (cohort Ⅰ, n=6), 5 of the 6 cases were composed of epithelial-predominant and were positive for WT-1 and CD56, respectively, and all were positive for CD57. All 6 cases revealed highly variable Ki-67 indices, ranging from 1% in some areas to 60% in others. 5 of the 6 cases harbored a BRAF V600E mutation. All cases in cohort I were followed up for 23 to 71 months, and all survived. In classical adult WT without MA-like areas cohort (cohort Ⅱ, n=13), all 7 cases with available material were negative for BRAF by IHC and none of them had any BRAF mutation. Conclusions: BRAF V600E mutations are frequently present in adult WT with overlapping morphologically features of MA, but not in those without. More importantly, adult WTs with overlapping histologic features of MA may be an intermediate entity between typical MA and WT that may have a favorable prognosis and possible therapeutic targets.

Clinical treatment and observation of the endophthalmitis caused by Bacillus cereus / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To analyze the clinical characteristics and antibiotic sensitivity of traumatic endophthalmitis caused by Bacillus cereus and discuss the early diagnosis and treatment measures.METHODS: The data of 15 patients(15 eyes)with Bacillus cereus endophthalmitis admitted to the Eye Trauma Center of Shaanxi Provincial Eye Hospital from January 2019 to December 2021 were collected. The injury time, injury condition, preoperative visual acuity, corrected visual acuity in the last follow-up, operation method, bacterial culture and drug sensitivity test results were recorded.RESULTS: Among the 15 patients(15 eyes), 5 eyes with simple corneal perforating wound were treated with wound debridement and suture combined with intraocular antibiotic injection. And another 10 eyes with penetrating injuries combined with traumatic cataract and intraocular foreign bodies were treated with debridement, cataract extraction, removal of intraocular foreign bodies, vitrectomy combined with silicone oil tamponade and intraocular antibiotic injection. Among the 15 patients, 11 patients(73%)were treated effectively and the eyeball was preserved, and 4 patients(27%)were treated ineffectively and ocular evisceration was performed. Among the 11 patients with eyeball retention, 1(9%)had decreased vision, 1(9%)had unchanged vision, 4(36%)had improved vision by 1 level, and 5(45%)had improved vision by 2 levels, and the postoperative visual acuity was significantly improved. Correlation analysis showed that the course of disease was negatively correlated with corrected visual acuity(rs=-0.762, P=0.001). The cultures of vitreous humor and aqueous humor samples of patients were all grown in Bacillus cereus, and susceptibility tests were sensitive to vancomycin.CONCLUSIONS: Vancomycin is an effective drug for the treatment of Bacillus cereus endophthalmitis. Vitrectomy combined with silicone oil tamponade and intravitreal injection of vancomycin are effective method for the treatment of Bacillus cereus endophthalmitis.

Radiomics based on biparametric MRI for the detection of significant residual prostate cancer after androgen deprivation therapy: using whole-mount histopathology as reference standard / 亚洲男科学杂志(英文版)

We aimed to study radiomics approach based on biparametric magnetic resonance imaging (MRI) for determining significant residual cancer after androgen deprivation therapy (ADT). Ninety-two post-ADT prostate cancer patients underwent MRI before prostatectomy (62 with significant residual disease and 30 with complete response or minimum residual disease [CR/MRD]). Totally, 100 significant residual, 52 CR/MRD lesions, and 70 benign tissues were selected according to pathology. First, 381 radiomics features were extracted from T2-weighted imaging, diffusion-weighted imaging, and apparent diffusion coefficient (ADC) maps. Optimal features were selected using a support vector machine with a recursive feature elimination algorithm (SVM-RFE). Then, ADC values of significant residual, CR/MRD lesions, and benign tissues were compared by one-way analysis of variance. Logistic regression was used to construct models with SVM features to differentiate between each pair of tissues. Third, the efficiencies of ADC value and radiomics models for differentiating the three tissues were assessed by area under receiver operating characteristic curve (AUC). The ADC value (mean ± standard deviation [s.d.]) of significant residual lesions ([1.10 ± 0.02] × 10-3 mm2 s-1) was significantly lower than that of CR/MRD ([1.17 ± 0.02] × 10-3 mm2 s-1), which was significantly lower than that of benign tissues ([1.30 ± 0.02] × 10-3 mm2 s-1; both P < 0.05). The SVM feature models were comparable to ADC value in distinguishing CR/MRD from benign tissue (AUC: 0.766 vs 0.792) and distinguishing residual from benign tissue (AUC: 0.825 vs 0.835) (both P > 0.05), but superior to ADC value in differentiating significant residual from CR/MRD (AUC: 0.748 vs 0.558; P = 0.041). Radiomics approach with biparametric MRI could promote the detection of significant residual prostate cancer after ADT.

Discrimination of cultivation modes of Dendrobium nobile based on content of mineral elements and ratios of nitrogen stable isotopes / 中国中药杂志

This study explored the feasibility of mineral element content and ratios of nitrogen isotopes to discriminate the cultivation mode of Dendrobium nobile in order to provide theoretical support for the discrimination of the cultivation mode of D. nobile. The content of 11 mineral elements(N, K, Ca, P, Mg, Na, Fe, Cu, Zn, Mn, and B) and nitrogen isotope ratios in D. nobile and its substrate samples in three cultivation methods(greenhouse cultivation, tree-attached cultivation, and stone-attached cultivation) were determined. According to the analysis of variance, principal component analysis, and stepwise discriminant analysis, the samples of different cultivation types were classified. The results showed that the nitrogen isotope ratios and the content of elements except for Zn were significantly different among different cultivation types of D. nobile(P<0.05). The results of correlation analysis showed that the nitrogen isotope ratios, mineral element content, and effective component content in D. nobile were correlated with the nitrogen isotope ratio and mineral element content in the corresponding substrate samples to varying degrees. Principal component analysis can preliminarily classify the samples of D. nobile, but some samples overlapped. Through stepwise discriminant analysis, six indicators, including δ~(15)N, K, Cu, P, Na, and Ca, were screened out, which could be used to establish the discriminant model of D. nobile cultivation methods, and the overall correct discrimination rates after back-substitution test, cross-check, and external validation were all 100%. Therefore, nitrogen isotope ratios and mineral element fingerprints combined with multivariate statistical analysis could effectively discriminate the cultivation types of D. nobile. The results of this study provide a new method for the identification of the cultivation type and production area of D. nobile and an experimental basis for the quality evaluation and quality control of D. nobile.

BACKGROUND@#Coronavirus disease 2019 (COVID-19) has become a worldwide life-threatening pandemic. Lianhua Qingwen is believed to possess the ability to treat or significantly improve the symptoms of COVID-19. These claims make it important to systematically evaluate the effects of using Lianhua Qingwen with Western medicine to treat COVID-19.@*OBJECTIVE@#To evaluate the safety and efficacy of combination therapy, employing Lianhua Qingwen with Western medicine, to treat COVID-19, using a meta-analysis approach.@*SEARCH STRATEGY@#China National Knowledge Infrastructure, Wanfang Database, VIP Database, PubMed, Embase, and Cochrane Library databases were searched for studies evaluating the effect of Lianhua Qingwen-Western medicine combination therapy in the treatment of COVID-19.@*INCLUSION CRITERIA@#(1) Research object: hospitalized patients meeting the diagnostic criteria of COVID-19 were included. (2) Intervention measures: patients in the treatment group received Lianhua Qingwen treatment combined with Western medicine, while the control group received either Western medicine or Chinese medicine treatment. (3) Research type: randomized controlled trials and retrospective study were included.@*DATA EXTRACTION AND ANALYSIS@#Two researchers extracted the first author, the proportion of males and females, age, body temperature, course of treatment, rate of disappearance of main symptoms, duration of fever, adverse reactions, and total effectiveness from the literature. Odds ratio (OR) and 95% confidence interval (CI) were used as the effect value for count data, and mean difference (MD) and 95% CI were used as the effect value for measurement data.@*RESULTS@#Six articles met the inclusion criteria, including a total of 856 COVID-19 patients. The meta-analysis showed that Lianhua Qingwen combination therapy achieved higher rates of fever reduction (OR = 3.43, 95% CI [1.78, 6.59], P = 0.0002), cough reduction (OR = 3.39, 95% CI [1.85, 6.23], P < 0.0001), recovery from shortness of breath (OR = 10.62, 95% CI [3.71, 30.40], P < 0.0001) and recovery from fatigue (OR = 2.82, 95% CI [1.44, 5.53], P = 0.003), higher total effectiveness rate (OR = 2.51, 95% CI [1.73, 3.64], P < 0.00001), and shorter time to recovery from fever (MD = -1.00, 95% CI [-1.04, 0.96], P < 0.00001), and did not increase the adverse reaction rate (OR = 0.65, 95% CI [0.42, 1.01], P = 0.06), compared to the single medication control.@*CONCLUSION@#The Lianhua Qingwen and Western medicine combination therapy is highly effective for COVID-19 patients and has good clinical safety. As only a small number of studies and patients were included in this review, more high-quality, multicenter, large-sample-size, randomized, double-blind, controlled trials are still needed for verification.

Prognostic value of primary tumor surgery in seminoma patients with distant metastasis at diagnosis: a population-based study / 亚洲男科学杂志(英文版)

The aims of this study were to determine the prognostic value of primary tumor surgery and identify optimal candidates for such surgery among patients with seminoma and distant metastasis at diagnosis. We identified 521 patients with seminoma and distant metastasis at diagnosis between 2004 and 2014 from the Surveillance, Epidemiology, and End Results database. Among these patients, 434 had undergone surgery, whereas 87 had not. The prognostic value of primary tumor surgery was assessed by Kaplan-Meier methods, log-rank analyses, and multivariate Cox's proportional hazards model. Survival curves and forest plots were also plotted. Survival analysis indicated that patients who underwent surgery had a better 5-year overall survival and cancer-specific survival than those who did not. Multivariate analyses demonstrated that primary tumor surgery is an independent prognostic factor for overall survival and cancer-specific survival, along with age at diagnosis, M stage, and marital status. In addition, primary tumor surgery still had considerable prognostic value in the subgroup of patients with lymph node metastasis. Further, forest plots demonstrated that patients with M1a stage, N1 or N2-3 stage, and a younger age at diagnosis (<60 years) may benefit from primary tumor surgery. In conclusion, our findings indicate that primary tumor surgery is correlated with improved survival in patients with seminoma and distant metastasis. Furthermore, primary tumor surgery is an independent prognostic indicator for patients with seminoma and distant metastasis.

The Ability of Baseline Triglycerides and Total Cholesterol Concentrations to Predict Incidence of Type 2 Diabetes Mellitus in Chinese Men and Women: A Longitudinal Study in Qingdao, China / 生物医学与环境科学（英文）

OBJECTIVE@#The purpose of this study was to assess the association between triglycerides (TG), total cholesterol (TC) at baseline, and type 2 diabetes mellitus (T2DM) incidence in a general Chinese population. Further, it aimed to evaluate the ability of TG and TC to predict T2DM incidence.@*METHODS@#Qingdao Diabetes Prevention Program participants recruited between 2006 and 2009 were followed up in 2012-2015. TG, TC, and T2DM status were measured. Cox proportional hazards models were used to estimate the association between TG, TC, and T2DM incidence. The receiver operating characteristic (ROC) curve was used to evaluate the ability of TG and TC to identify T2DM participants.@*RESULTS@#The incidence of T2DM significantly increased with TG in women and TC in both men and women (Ptrend 1.15 and > 1.23 mmol/L in men and women, respectively. For TC, they were > 5.17 and > 5.77 mmol/L in men and women, respectively. The area under the ROCs of TG and TC were 0.54 (0.51-0.57) and 0.55 (0.52-0.58), respectively, in men, and 0.60 (0.58-0.62) and 0.59 (0.56-0.61), respectively, in women.@*CONCLUSION@#Elevated TG and TC were risk factors for T2DM incidence. However, no predictive capacity was found for both factors to identify T2DM incidence in Chinese men and women. Hence, TG and TC levels in both Chinese men and women might be used for decreasing the incidence of T2DM but no clinical predictive capacity for T2DM.

Association of vitamin D and risk of hypertension in Henan rural population / 中华疾病控制杂志

Objective The purpose of this study was to investigate the prevalence of vitamin D deficiency and hypertension in Henan rural residents, and to explore the association between vitamin D and risk of hypertension. Methods 2 013 Henan rural participants aged 18-80 years were recruited from a cross-sectional study. Logistic regression models and restricted cubic spline model were used to evaluate odds ratios (OR), 95% confidence intervals (95% CI) and dose-response relationship between vitamin D and risk of hypertension. Results In total population, the prevalence of hypertension was 40.34% (30.64% after age-standard), and the mean serum 25-(OH)D was (24.50 ± 16.18) ng/ml, and 53.95% of all participants were presenting vitamin D deficiency. Compared with non-hypertension, a lower level of serum 25-(OH)D was observed in people with hypertension. The prevalence of hypertension was 45.21% in vitamin D deficient group which was higher than in the vitamin D sufficient group (31.07%). Compared with the vitamin D sufficient group, the risk of hypertension was increase in the vitamin D deficient group (OR=1.59, 95% CI: 1.21-2.10), and the risk of hypertension decreased by 14% for every 10 ng/ml increase in serum 25-(OH) D levels. Moreover, an L-shaped relationship was observed between 25-(OH)D concentration and risk of hypertension. Conclusion Vitamin D deficiency is associated with risk of hypertension and there is an L-shaped relationship between 25-(OH)D concentration and risk of hypertension.

Characteristics of mandible and mandibular dentition according to vertical facial skeletal features of adolescents / 华西口腔医学杂志

OBJECTIVE@#We aim to examine teenagers with varying vertical facial skeletal types with near-normal occlusion. We further aim to identify and study mandibular morphology and dentition characteristics to establish normal ranges and variations for future clinical reference.@*METHODS@#According to the results of the case studies, 42 adolescents with near-normal occlusion were divided into three groups, namely, low- (7 cases), average- (23 cases) and high-angle (12 cases) groups. We used Invivo 5 software for Digital Imaging and Communications in Medicine (DICOM) data to calculate the cant of occlusal plane, axis corner of L6, ∠L1/MP, ∠L6/MP, Balkwill angle and Bonwill triangle of each group.@*RESULTS@#Markedly, the finding shows that the cant of occlusal plane and axis corner of L6 in the low-angle group were smaller than those of the other two groups. In the average-angle group, ∠L1/MP was larger than that of the high-angle group. Lastly, in the high-angle group, ∠L6/MP was smaller than those of the two other groups. On the one hand, these differences were considered statistically significant (P0.05).@*CONCLUSIONS@#In the low-angle group, the parallelisation of the occlusal plane tends to be more obvious compared with the two other groups. In the coronal section of the low-angle group, the axis of the mandibular first molar is up-right, whereas it is distally tilted in the sagittal section of the high-angle group. Furthermore, a number of differences are noted in the adult groups. Factors, such as aging and development in the craniofacial region, lead to changes in functional occlusion.

Conclusion Six mono-carbonyl curcumin analogs 1a-1f were synthesized, and 1f showed much better anti-proliferation activity on A549 and NCI-H460 cells.

Compare and Contrast of the Diagnosis of Cerebral Malformation on 2D Ultrasonography, 3D Ultrasonography against MRI / 昆明医科大学学报

Objective to compare and contrast the diagnosis results on 2D and 3D Ultrasonogrpahy against MRI. Method A 2D Ultrasonography was applied during a conventional prenatal sonography checking with a 3D Sonography assessment subsequently conducted to follow up on 49 fetus suspected of brain malformation.Furthermore, a MRI scan was taken within 24 hours after the 3D Sonography checking in our hospital as a final test. Data collections from all three assessments were completed, and an analysis of the comparisons of these three methods were done. Results Among these 49 fetus with confirmed or suspected brain malformation, there were two cases of misdiagnoses of Dandy-Walker Malformation assessed by 2D sonography, with a misdiagnosis rate of 40％, (P ＜ 0.05) indicating a statistically significant result; misdiagnosis rate of Fetal Ventriculomegaly and Isolated Broadening Posterior Fossa were calculated as 26.7％ and 33.3％ respectively (P ＜0.05), a statistically significant result. Overall, there were two cases with Cerebellum Malformation, from in which one case was identified by MRI, and the other one was misdiagnosed, with a misdiagnosis rate of 50.0％.In total, there were 2 cases of Holoprosencephaly, in which one was identified by Prenatal MRI, and the other was misdiagnosed (P ＜ 0.05), a statistically significant result. Conclusions All three assessments of 2D ultrasonography, 3D ultrasonography and MRI have their own advantages and disadvantages. In short, 2D Sonography is suggested to be applied for screening out cases with brain malformation, together with 3D Sonography as a complementary assessment. MRI can also be an effective and significant complement for sonography in completing and readdressing the final ultrasonic results.

Glypican-3-specific cytotoxic T lymphocytes induced by human leucocyte antigen-A*0201-restricted peptide effectively kill hepatocellular carcinoma cells in vitro

OBJECTIVE@#To investigate potential human leucocyte antigen (HLA)-A2-restricted epitope peptides of glypican-3 (GPC3) and determine the cytotoxicity of peptide-specific cytotoxic T lymphocytes (CTLs) against hepatocellular carcinoma (HCC) cells.@*METHODS@#The potential HLA-A*0201-restricted GPC3 peptides were screened using computer algorithms, T2 cell-binding affinity and stability of peptide/HLA-A*0201 complex assay. The peptide-specific CTLs were generated and their cytotoxicity against GPC3 SMMC 7721 and HepG2 cells was detected using IFN-γ based enzyme-linked immunospot and lactate dehydrogenase release assays in vitro.@*RESULTS@#A total of six peptides were identified for bindings to HAL-A2 and the GPC3 522-530 and GPC3 229-237 peptides with HLA-A*0201 molecules displayed high binding affinity and stability. The CTLs induced by the GPC3 522-530 or positive control GPC3 144-152 peptide responded to the peptide by producing IFN-γ, which were abrogated by treatment with anti-HLA-A2 antibody. The GPC3 522-530-specific CTLs responded to and killed SMMC 7721 and HepG2 cells, instead of GPC3-silenced SMMC 7721 or HepG2 cells. GPC3 522-530-specific CTLs response to HCC cells was blocked by anti-HLA-A2 antibody.@*CONCLUSIONS@#The GPC3 522-530 peptide contains antigen-determinant and its specific CTLs can effectively kill HCC in a HLA-A2-restricted and peptide-dependent manner. Our findings suggest that this peptide may be valuable for development of therapeutic vaccine.

OBJECTIVE@#To ascertain the influence of light intensity and water content of medium on the total dendrobine of Dendrobium nobile (D. nobile).@*METHOD@#The principal component analysis combined with total dendrobine accumulation was conducted to assess the yield and quality of D. nobile in all treatments. In the experiment, D. nobile plants were cultivated in greenhouse as tested materials, and complete test of 9 treatments was adopted with relative light intensities 75.02%, 39.74%, 29.93% and relative water content of medium 50%, 65%, 80%. The plants were treated in June and harvested till December. Indexes including agronomic traits, fresh weight and dry weight of stem and leaf, ash content, extract, and dendrobine were measured.@*RESULTS@#Under the light intensity treatments of 75.02% with 50%, 65%, 80% water content of medium, the basal stems of plants were comparatively thicker with more leaves, and the fresh weight and dry weight of stems and leaves were significantly higher than other 6 treatments. Leaves in all treatments contained dendrobine. Under the light intensity treatments of 75.02% with 50%, 65%, 80% water content of medium, dendrobine content of leaves was lower while dendrobine contents of other treatments were more than 0.60%. After comprehensive assessment through the principal component analysis and total dendrobine accumulation, the results showed that 3 treatments with relative light intensity of 75.02% ranked the top three.@*CONCLUSIONS@#In brief, the moderately strong light intensity and water content of medium from low to medium can facilitate the growth and yield of D. nobile plants, while light intensity from moderately weak to weak can enhance the dendrobine content.
