ABSTRACT

Objective:To analyze the risk factors for keratoconus through a systematic review of secondary literature.Methods:Analytical studies from Cochrane Library, PubMed, Embase database, CNKI, Wanfang Periodicals Database, VIP Chinese Science and Technology Journal Database published from January 2000 to May 2021 were searched, most of which were about the keratoconus occurrence and progression and the valid data were extracted.The case-control and the cohort studies were evaluated according to the Newcastle-Ottawa Scale.The categorical variables for combined effect size were odds ratio( OR) and 95% confidence interval ( CI). The heterogeneity was evaluated via the Q test and I2 test.The fixed-effect model was adopted when P>0.1 or I2≤50%, while the random effect model was adopted when I2>50%.The sources of heterogeneity in included evaluation indexes were analyzed through subgroup and sensitivity analysis.The publication bias was evaluated by Egger tests, Harbord tests, Peters tests and funnel plots. Results:A total of 21 papers with 30 124 keratoconus cases and 59 012 control cases enrolled, including 18 case-control studies and 3 cohort studies, whose data were from 10 countries, were included.The NOS scores of the studies were not less than 7 points.The Meta-analysis results indicated that family history ( OR: 8.68, 95% CI: 6.30-11.97), eye rubbing ( OR: 4.62, 95% CI: 3.75-5.70), allergy ( OR: 2.34, 95% CI: 1.73-3.16), obstructive sleep apnea ( OR: 1.53, 95% CI: 1.12-2.10) and Down syndrome ( OR: 7.09, 95% CI: 4.19-11.99) were the risk factors for keratoconus, and mitral valve prolapse ( P>0.05) was not a risk factor for keratoconus, and diabetes ( OR: 0.63, 95% CI: 0.50-0.79) was a protective factor for keratoconus.The subgroup analysis results indicated that the heterogeneity in allergy was partially due to the specific disease classification, and the heterogeneity in diabetes and obstructive sleep apnea was totally owing to the source of the cases.The sensitivity study showed that the results were robust after changing the analysis model.There was no bias in the included studies. Conclusions:Family history, eye rubbing, allergy, obstructive sleep apnea and Down syndrome are risk factors for keratoconus, and diabetes is a protective factor for keratoconus.

ABSTRACT

Objective:To evaluate the diagnostic efficiency of hypersensitivity quantitative fecal immunochemical test (hs-qFIT) in colorectal cancer (CRC) and advanced adenoma.Methods:From July to December 2020, consecutive patients aged 50 to 75 years who underwent colonoscopy in Qilu Hospital of Shandong University, and had the Asia-Pacific colorectal screening score of medium or high risk were enrolled. All patients were requested to complete two hs-qFIT before colonoscopy. The diagnostic efficacy of hs-qFIT for CRC and advanced adenoma were assessed. Receiver operating characteristic curve of hs-qFIT in CRC diagnosis was drawn and the area under the curve (AUC) was calculated.Results:A total of 811 patients including 20 (2.5%) cases of CRC, 47 (5.8%) cases of advanced adenoma, 206 (25.4%) cases of non-advanced adenoma, 219 (27.0%) cases of non-adenomatous polyp, 76 (9.4%) cases of other colorectal lesions and 243 (30.0%) cases of non-colorectal lesions were involved. When the fecal hemoglobin cut-off values were 10, 30, 50, 75 and 100 ng/mL, the positive rates of hs-qFIT detection were 17.9% (145/811), 10.9% (88/811), 8.3% (67/811), 7.4% (60/811) and 5.8% (47/811), respectively. When the cut-off value of fecal hemoglobin decreased from 100 ng/mL to 10 ng/mL, the sensitivity of hs-qFIT for CRC diagnosis increased from 90.0% to 100.0%, and the specificity decreased from 96.3% to 84.2%; and the sensitivity of hs-qFIT for the diagnosis of advanced adenoma increased from 19.1% to 66.0%, and the specificity decreased from 95.0% to 85.1%. The AUC of hs-qFIT for the diagnosis of CRC and advanced adenoma were 0.981 (95% confidence interval ( CI) 0.970 to 0.992) and 0.846 (95% CI 0.807 to 0.886), respectively. When the optimal cut-off values were taken, the sensitivity and specificity were 100.0% and 91.2% for the diagnosis of CRC, and 66.0% and 85.3% for the diagnosis of advanced adenoma, respectively. Conclusion:Hs-qFIT can help the early screening of CRC and advanced adenoma.

ABSTRACT

Objective:To explore the effect of a Chinese medicinal composition ( Xiadanqi) on the prevention of radon exposure induced injuries of lung in vitro and in vivo. Methods:Mice were randomly divided into three groups of blank control group, radon-exposed group alone and radon-exposed group intervened with Chinese medicinal composition. The pathological changes of lung tissues in each group after 120 WLM were observed by HE and Masson staining, and the expressions of α-SMA protein and Vimentin protein in lung tissues were detected by immunohistochemistry staining. The levels of oxidative stress in lung tissue of each group were detected with SOD and MDA kits. At the same time, a radon exposed cell model and a radon exposure + Xiadanqi intervention cell model were constructed using an ecological radon chamber. The cell adhesion abilities of different groups were detected by an adhesion kit. The cell migration ability of each group was determined by the transwell migration experiment. The expression of E-cadherin and Vimentin protein was detected by Western blot. Results:Compared with the radon exposure group, the concentration of MDA was decreased ( t=4.43, P<0.05), the activity of SOD was increased ( t=3.22, P<0.05), and α-SMA and Vimentin protein expressions were decreased ( t=3.08, 7.57, P<0.05) in lung tissue of mice intervened with 2 mg/g Xiadanqi. In vitro, compared with radon exposure group, the migration ability was reduced ( t=4.78, 13.01, P<0.05), the cell adhesion property was enhanced ( t=3.41, 12.55, P<0.05), the expression of E-cadherin protein was increased ( t=2.96, 19.57, P<0.05), and the expression of Vimentin protein was obviously reduced ( t=21.00, 33.32, P<0.05) in radon-exposed cells with the treatment of Chinese medicine (150 μg/ml and 200 μg/ml). Conclusions:The Chinese medicinal composition ( Xiadanqi) has a certain radioprotective effect on radon exposure induced injury by reducing oxidative stress, attenuating EMT and fibrosis, and thus it may be applied as a protective agent for radon induced injury.

ABSTRACT

OBJECTIVE@#To explore the genetic etiology of a neonate with suggestive features of Cornelia de Lange Syndrome (CdLS).@*METHODS@#Chromosome karyotyping, copy number variation sequencing (CNV-seq) and whole exome sequencing (WES) were carried out for the child. Meanwhile, peripheral venous blood samples were taken from his parents for verifying the suspected pathogenic variants detected in the child.@*RESULTS@#The child has exhibited developmental delay, microcephaly, ptosis, micrognathia, and low ear setting, and was suspected as CdLS. No abnormality was found by karyotyping and CNV-seq analysis. WES has detected 5 heterogeneous variants and 1 hemizygous variant on the X chromosome. Combining the genetic pattern and result of family verification, a hemizygous C.3500T>C (p.ile1167thr) of the SMC1A gene was predicted to underlay the clinical manifestations of the patient. This variant was not recorded in the dbSNP and gnomAD database. PolyPhen2, Provean, SIFT all predicted the variant to be harmful, and PhastCons conservative prediction is was a conservative mutation. ACMG variant classification standard evidence supports are PM2, PP2, and PP3.@*CONCLUSION@#The novel c.3500T>C (p.Ile1167Thr) missense mutation of the SMC1A gene probably underlay the genetic etiology of CdLS in this child. Above results has enriched the mutation spectrum of CdLS type II, and facilitated clinical counseling for this family.

ABSTRACT

Objective:To compare the prediction efficiency of traditional linear regression model and four machine learning models on the learning behavior of clinical medical postgraduates, and to explore the pros and cons and applicability of different prediction models.Methods:A total of 6,922 clinical medical postgraduates were surveyed, their comprehensive learning behavior scores were obtained through the learning behavior scale. In the training set, Lasso linear regression and artificial neural network, decision tree, Bootstrap random forest, and lifting tree were used to build prediction models respectively. The above models were used to predict the validation set data and compare the prediction efficiency.Results:The comprehensive learning behavior score of clinical medical postgraduates was (3.31±0.54) points, and the overall compliance rate was 74.02%. In the linear regression model, the influence of age, school level, degree type, learning interest, pressure and satisfaction on learning behavior were statistically significant. In the prediction of validation set, the sensitivity, specificity, and accuracy of the linear regression model were 0.484, 0.914, and 0.801, respectively. The indexes of the four machine learning models were higher than those of the traditional linear regression model, and the Bootstrap random forest had the highest elevation.Conclusion:The linear regression model has a good prediction effect on learning behavior, and machine learning is superior to linear regression model in terms of accuracy of prediction. However, traditional linear regression models are superior to machine learning models in computational efficiency and interpretability.

ABSTRACT

Objective:To develop intelligent quality-control system (IQCS) based on deep convolutional neural networks (DCNN), and to prospectively evaluate the clinical feasibility of this system.Methods:Aimed at quality control objectives during gastroscopy such as the observation integrity of gastric mucosal, gastric mucosa visibility, time spent on gastroendoscopy and suspicious gastric cancer detection, four DCNN models including gastroscopic scanning location recognition model, gastric mucosa visibility recognition model, in vivo and in vitro identification model and gastric cancer detection model were designed. A total of 98 385 white light gastroscopy images were retrospectively collected from multiple centers for training and testing the DCNN models. The accuracy, sensitivity and specificity of each model were calculated and the receiver operating characteristic (ROC) curve was drawn. The models were integrated and formed the multi-function integrated IQCS. At the center of gastroendoscopy, Qilu Hospital of Shandong University, 100 consecutive patients who underwent routine gastroscopy were prospectively enrolled. The feasibility of IQCS in real clinical practice was evaluated. The condition of each quality control function of the system (average error point out or correct rate) and the detection of lesions after the examination were recorded. Results:The accuracy, sensitivity and specificity of the model of gastroscopic scanning location recognition to identify each site were 98.40% to 99.85%, 61.95% to 100.00% and 98.65% to 100.00%, respectively; the area under curve (AUC) of ROC curve ranged from 0.997 6 to 1.000 0. The accuracy, sensitivity and specificity of the model of gastric mucosa visibility recognition to identity the mucosal visibility were 97.02% to 98.27%, 85.14% to 99.28% and 93.72% to 100.00%, respectively. The accuracy, sensitivity and specificity of the model of in vivo and in vitro identification were 97.27%, 99.85% and 94.50%, respectively; the AUC of ROC was 0.961 5. The accuracy, sensitivity and specificity of the model of gastric cancer detection were 95.92%, 95.64% and 96.05%, respectively; the AUC of ROC was 0.975 9. The results of feasibility evaluation of IQCS indicated that in the quality control of gastric mucosa observation integrity, the system average error was 0.32 time/case; in the quality control of mucosal visibility, the system average error was 0.47 time/case; the correct rate of intelligent timing during gastroscopy was 96.00%, in the quality control of suspicious gastric cancer detection, the system average error was 0.36 time/case. A total of 3 cases of gastric cancer and 1 case of high grade gastric intraepithelial neoplasia were detected. The system could accurately identify the location. Conclusions:Gastroscopy IQCS can accurately achieve quality control in the observation integrity of gastric mucosa, gastric mucosa visibility, time spent on gastroendoscopy and suspicious gastric cancer detection in actual examination, which makes accurate and efficient gastroscopy quality control possible.

ABSTRACT

The current document is based on a consensus reached by a panel of experts from the Chinese Society of Allergy and the Chinese Society of Otorhinolaryngology-Head and Neck Surgery, Rhinology Group. Chronic rhinosinusitis (CRS) affects approximately 8% of Chinese adults. The inflammatory and remodeling mechanisms of CRS in the Chinese population differ from those observed in the populations of European descent. Recently, precision medicine has been used to treat inflammation by targeting key biomarkers that are involved in the process. However, there are no CRS guidelines or a consensus available from China that can be shared with the international academia. The guidelines presented in this paper cover the epidemiology, economic burden, genetics and epigenetics, mechanisms, phenotypes and endotypes, diagnosis and differential diagnosis, management, and the current status of CRS in China. These guidelines—with a focus on China—will improve the abilities of clinical and medical staff during the treatment of CRS. Additionally, they will help international agencies in improving the verification of CRS endotypes, mapping of eosinophilic shifts, the identification of suitable biomarkers for endotyping, and predicting responses to therapies. In conclusion, these guidelines will help select therapies, such as pharmacotherapy, surgical approaches and innovative biotherapeutics, which are tailored to each of the individual CRS endotypes.

ABSTRACT

Medical education reform mainly focused on the reform of the form and method of teaching but neglected the reform of the teaching concept that has truly penetrated into all aspects of teaching. With reference to the reflection on the teaching goal of physiology and the need of the cultivation of "post competency", the core concepts of physiological teaching are summarized into the following four aspects: "Three Outlooks" must be positive to help students establish a balanced view, a dialectical view, and a holistic view; "Three Fundamentals" should be solid to help students master basic knowledge structure system, cultivate basic knowledge acquisition ability, and improve basic operation skills; students should attach importance to learning and use; humanistic quality should be strengthened. The above core concepts have been widely recognized by students in teaching practice , and clinical medical students have significantly better evaluation of the core concepts than nursing students . Future direction of the subsequent teaching reform should be how to refine the contents of lectures under the guidance of the teaching concepts to adapt to the increasingly detailed specialities.

ABSTRACT

Stroke seriously endangers people's life and health because of its high prevalence, disability and recurrence rate. Among them, large vessel occlusive stroke (LVOS) has the worst outcome. Rapid recovery of cerebral perfusion is the key to improve the outcomes of patients with LVOS. As a new type of treatment, endovascular treatment can effectively recanalize the occluded blood vessels and extend the treatment time window. The level of collateral circulation determines the severity of symptoms, treatment choices, treatment effects and outcomes in patients with LVOS. This article summarizes the clinical factors related to collateral circulation compensation in patients with LVOS, and focuses on the application value of imaging technology in the evaluation of collateral circulation.

ABSTRACT

Clinical data of 12 cases of Trousseau syndrome with cerebral infarction as initial presentation admitted in the neurology department of the Fourth Affiliated Hospital of Hebei Medical University from December 2011 to December 2017 were retrospectively analyzed.Of the 12 patients,4 cases had risk factors for cerebral infarction and 8 ones had no risk factors.There were 2 patients with 1 lesion and 10 patients with two or more lesions in brain imaging.The infarction lesions of 9 patients were located in 2 or more arterial blood supply areas.Ten patients showed an elevated plasma D-dimer level,5 had elevated fibrinogen level,7 showed increased blood platelet count and 8 had increased homocysteine level.Ten cases were confirmed by pathology,2 cases by clinic and imaging diagnosis.The study suggests that multiple lesions with several cerebral arteries involved,high plasma D-dimer and fibrinogen levels may be the clinical characteristics of Trousseau syndrome with initial presentation as acute ischemic stroke and lacking of risk factors.The hypercoagulation state may be the important pathogenesis of this disorder.

ABSTRACT

Allergic rhinitis (AR) is a global health problem that causes major illnesses and disabilities worldwide. Epidemiologic studies have demonstrated that the prevalence of AR has increased progressively over the last few decades in more developed countries and currently affects up to 40% of the population worldwide. Likewise, a rising trend of AR has also been observed over the last 2–3 decades in developing countries including China, with the prevalence of AR varying widely in these countries. A survey of self-reported AR over a 6-year period in the general Chinese adult population reported that the standardized prevalence of adult AR increased from 11.1% in 2005 to 17.6% in 2011. An increasing number of original articles and imporclinical trials on the epidemiology, pathophysiologic mechanisms, diagnosis, management and comorbidities of AR in Chinese subjects have been published in international peer-reviewed journals over the past 2 decades, and substantially added to our understanding of this disease as a global problem. Although guidelines for the diagnosis and treatment of AR in Chinese subjects have also been published, they have not been translated into English and therefore not generally accessible for reference to non-Chinese speaking international medical communities. Moreover, methods for the diagnosis and treatment of AR in China have not been standardized entirely and some patients are still treated according to regional preferences. Thus, the present guidelines have been developed by the Chinese Society of Allergy to be accessible to both national and international medical communities involved in the management of AR patients. These guidelines have been prepared in line with existing international guidelines to provide evidence-based recommendations for the diagnosis and management of AR in China.

ABSTRACT

Objective To investigate the expression of Gli1 protein in colorectal cancer (CRC) tissues,and evaluate its association with the prognoses of the patients.Methods A total of 106 patients were enrolled and their clinicopathological characteristics were analyzed.The expression of Gli1 proteins were detected by immunohistochemical staining,and its association with time to recurrence/metastasis (TTR) and overall survival (OS) of the patients were analyzed.Results The positive rate and expression intensity of Gli1 protein in recurrent or metastatic tumor tissues were higher than those in non-recurrent and non-metastatic tumor tissues [86.84 % (33/38) vs.58.82 % (40/68),1.32 scores vs.0.71 scores,both P < 0.01),while the positive rate and expression intensity of Ki-67 protein remained no difference between both groups [97.37 % (37/38) vs.91.18 % (62/68),1.89 scores vs.1.75 scores,both P > 0.05).The positive rates and expression intensities of Gli1 and Ki-67 proteins in CRC tissues were higher than those in adjacent tissues [26.42 % (28/106) and 0.27 scores;4.72 %(5/106),0.05 scores] and normal tissues [3.33 % (1/106),0.03 scores;0,0.00 scores] (all P < 0.01).Results of univariate analysis showed that the expression of Gli1 protein,tumor grade and lymph node involvement were significantly associated with TTR,but all of the clinicopathological factors had no obvious association with OS.The association remained significant between the expression of Gli1 protein and TTR in multivariate analysis (P < 0.01).Conclusion The expression of Gli1 protein is an independent prognostic marker of recurrence or metastasis in CRC patients,its high expression implicates a high risk of CRC recurrence or metastasis.

ABSTRACT

Pancreatic cystic lesions (PCLs)have various pathological types,extremely different biological behaviors,and different progno-sis.Current diagnosis of PCLs mainly depends on a comprehensive analysis of the patient's medical history,clinical manifestations,imaging examinations,serological examinations,fine needle aspiration biopsy,and cytological examination of cyst fluid.Needle -based confocal la-ser endomicroscopy (nCLE)is a novel method of microscopic endoscopy and is compatible with 19 -gauge puncture needle.Under the guid-ance of endoscopic ultrasound,nCLE can achieve real -time in vivo imaging of the cellular and subcellular structures of diseased tissues and thus helps with the accurate diagnosis of PCLs.This article reviews the application of nCLE in the diagnosis of PCLs.

ABSTRACT

Objective To evaluate the efficacy and safety of Houpu Paiqi mixture in treatment of functional dyspepsia (FD)with abdominal distension symptom.Methods From July 2014 to June 2015 , in nine centers,a total of 162 FD patients with abdominal distension symptom and met Rome Ⅲpostprandial distress syndrome (PDS)diagnostic criteria were enrolled.All patients were randomly divided into trial group and control group,81 patients in either group.The patients of trial group and control group took Houpu Paiqi mixture or placebo,respectively,25 mL per time,twice daily,and both the courses of treatment were two weeks.Before and after the treatment,the improvement of main symptoms,total clinical efficacy rate and efficacy of traditional medicine between two groups were compared.Chi square test,Fisher exact probability method and Wilcoxon test were performed for statistical analysis.Results According to the results of per-protocol (PP)analysis,the total efficacy rate of trial group and control group was 69.4% (50/72)and 59.2% (42/71),respectively,and there was no statistically significant difference in total efficacy rate between the two groups (χ2 =1 .650,P =0.199 ). And there was no statistically significant difference in the improvement of PDS main symptoms(postprandial fullnessand early satiety)between the two groups (56.3% ±27.9% vs 54.4% ±32.1%,t =0.606,P =0.727 ).For those with baseline symptom score over 14,median early satiety score of trial group after the treatment was 0,which was lower than that of control group,and the difference was statistically significant (Z =-2.370,P =0.018).The total efficacy rate of traditional medicine of trial group was 80.8% (59/73 )and that of control group was 72.0% (54/75 ),and the difference was not statistically significant (χ2 = 0.676,P =0.411 ).Conclusion Houpu Paiqi mixture has certain efficacy in FD with abdominal distension,and could be used for the treatment of PDS-predominant FD.
