ABSTRACT
Objective: To investigate the relationship between miR-199b and clinicopathologic features and prognosis of patients with colorectal cancer. Methods: Cancer tissues and adjacent normal tissues of 202 patients with colorectal cancer treated in Cancer Hospital of Chinese Academy of Medical Sciences from March to December 2011 were collected. Reverse transcription-quantitative real-time polymerase chain reaction was used to detect the expression level of miR-199b in colorectal cancer tissues and corresponding adjacent normal tissues. Kaplan-Meier method and Log rank test were used for survival analysis, and receiver operating characteristic (ROC) curve was used to evaluate the prognostic value of miR-199b in colorectal cancer patients. Results: The relative expression level of miR-199b in colorectal cancer tissues (-7.88±0.11) was lower than that in adjacent normal tissues (-6.49±0.12, P<0.001). The expression level of miR-199b in colorectal cancer tissues with lymph node metastasis (-7.51±0.14) was higher than that in colorectal cancer tissues without lymph node metastasis (-8.23±0.17, P<0.001). The relative expression levels of miR-199b in stage Ⅰ/Ⅱ, Ⅲ and Ⅳ colorectal cancer tissues were gradually increased, which were -8.26±0.17, -7.70±0.16 and -6.57±0.27, respectively, and the difference was statistically significant (P<0.001). The 5-year survival rates of patients with high and low expressions of miR-199b were 75.6% and 84.6%(P=0.045) respectively. ROC curve showed that when miR-199b was -7.965, the area under the curve was 0.578 (95% CI: 0.468, 0.688). Conclusion: The high expression of miR-199b in colorectal cancer tissues is associated with late TNM stage, lymph node metastasis and poor prognosis in colorectal cancer patients, and miR-199b may be used as a potential marker for postoperative progress and prognosis in colorectal cancer patients.

Peripheral retinal degeneration is a typical lesion in ophthalmic clinical practice. Each type of degeneration affects distinct retinal layers and may lead to sight-threatening complications. Due to its specific location, where current ophthalmic imaging technologies have difficulties observing, the pathogenesis remains unclear despite previous works. This review outlines the characteristics of peripheral retinal degeneration by different wide-field imaging technologies, including ultra-wide field fundus imaging, wide field spectral domain optical coherence tomography, optical coherence tomography angiography and fundus fluorescein angiography, as well as new perspectives on their pathogenesis or pathological characteristics so as to provide new ideas for clinical diagnosis and management. Due to the small size of sample and the lack of prospective and long-term observation of multimodal imaging, it is still impossible to comprehensively evaluate the progression and risk of different types of degeneration. Therefore, it is expected that wide-field multimodal imaging technology will be more widely applied to study the mechanism of peripheral retinal degeneration and guide the clinical practice options.
ABSTRACT
AIM: To investigate the effects of modified Zhujing Pill on the mitochondrion structure and dynamin-related protein of retinal pigment epithelial cells(RPEs)in mice with form deprivation myopia.METHODS: 3-week-old C57BL/6J mice were randomly divided into control group, model group and Chinese medicine group, with 10 mice in each group. Myopia model of the right eye of mice was established by means of form deprivation in model and Chinese medicine groups. After 4wk, the Chinese medicine group were given intragastric administration of modified Zhujing Pill suspension 0.546g/(kg·d)(0.2mL/d)for 4wk, and same amount of saline was given to mice in other groups at the same time of modeling. The axial length and diopter of the right eye of the mouse were measured before and after the experiment by A-ultrasound and a strip retinoscope respectively. At the end of the experiment, the mitochondrial ultrastructure of RPEs was observed by transmission electron microscope. Western blot, and real-time fluorescent quantitative PCR(q-PCR)were used to detect quantitative and gene expression of mitofusin 1(MFN1), optic atrophy 1(OPA1), and dynamin-related protein 1(DRP1)in retinal tissues respectively.RESULTS: At the beginning of the experiment, there was no statistically significant difference in axial length and diopter of the right eye of the mouse in control, model and Chinese medicine groups(P>0.05). At the end of the experiment, compared with the control group, the mice in the model group and the Chinese medicine group had lower diopter and continuously prolonged axial length(all P<0.05), while the mice in the Chinese medicine group had significantly shorter axial length and higher diopter than the model group(all P<0.05). Western blot and q-PCR results showed that the relative expression of MFN1 and OPA1 decreased and DRP1 increased in both the model group and the Chinese medicine group compared with the control group(all P<0.05), and the relative expression of MFN1 and OPA1 increased in the Chinese medicine group compared with the model group(all P<0.05). The electron microscopic results showed that the mitochondria in the right retina of the mice were only mildly swollen in the Chinese medicine group, while the mitochondria in the model group were obviously swollen and disordered and empty.CONCLUSION: Modified Zhujing Pill could protect the retinal mitochondria by regulating the key proteins of mitochondrial dynamics(MFN1, OPA1, and DRP1), and it has a protective effect on the retina of axial myopic mice.

ABSTRACT
Pachychoroid spectrum diseases(PSD)have been defined as a group of diseases with similar choroidal features and pathological processes, such as central serous chorioretinopathy(CSC), polypoidal choroidal vasculopathy(PCV), etc. The main features are the changes in the thickness of vascular layers of the choroid and increasing vascular permeability. The development of modern ophthalmic imaging devices represented by optical coherence tomography angiography(OCTA)allowed intuitive investigation of the changes in the choroidal vascular layers, which gives a new insight into the pathogenesis of this spectrum diseases. This article summarizes the common clinical characteristics of healthy individuals and PSD and reviews the latest imaging findings. Whether each type of PSD is a phenotype of the same disease at different stages or other with similar characteristics was discussed from different perspectives, such as genetic background and anatomical structure, providing a reference for the study of pathogenesis, early clinical diagnosis, and prevention and treatment of this disease.

Sterility test, bacterial endotoxins test, abnormal toxicity test and the acetonitrile residue all met the requirements of Pharmacopoeia of the People′ s Republic of China (2020 Volume Ⅳ). The 18F-mFBG PET/CT imaging disclosed high uptake in pheochromocytoma and clear localization of lesions. Conclusions:The automatic radiolabeling of the NET targeted tracer 18F-mFBG is successfully realized by commercially available synthesis module, and the production quality meets all requirements for clinical translation. 18F-mFBG has a potential to image neuroendocrine lesions in clinical setting.
ABSTRACT
Objective:To explore the value of deep learning technology based on mammography in differentiating for breast imaging reporting and data system (BI-RADS) category 3 and 4 lesions.Methods:The clinical and imaging data of 305 patients with 314 lesions assessed as BI-RADS category 3 and 4 by mammography were analyzed retrospectively in Shenzhen People′s Hospital and Shenzhen Luohu People′s Hospital from January to December 2020. All 305 patients were female, aged 21 to 83 (47±12) years. Two general radiologists (general radiologist A and general radiologist B) with 5 and 6 years of work experience and two professional breast imaging diagnostic radiologists (professional radiologist A and professional radiologist B) with 21 years of work experience and specialized breast imaging training were randomly assigned to read the imaging independently at a 1∶1 ratio, and then to read the imaging again in combination with the deep learning system. Finally, breast lesions were reclassified into BI-RADS category 3 or 4. The receiver operating characteristic curve and area under the curve (AUC) were used to evaluate the diagnostic performance, and the differences of AUCs were compared by DeLong method.Results:The AUC of general radiologist A combined with deep learning system to reclassify BI-RADS category 3 and 4 breast lesions was significantly higher than that of general radiologist A alone (AUC=0.79, 0.63, Z=2.82, P=0.005, respectively). The AUC of general radiologist B combined with deep learning system to reclassify BI-RADS category 3 and 4 breast lesions was significantly higher than that of general radiologist B (AUC=0.83, 0.64, Z=3.32, P=0.001, respectively). There was no significant difference in the AUCs between professional radiologist A combined with deep learning system and professional radiologist A, and professional radiologist B combined with deep learning system and professional radiologist B in reclassifying BI-RADS category 3 and 4 breast lesions ( P>0.05). Conclusion:The deep learning system based on mammography is more effective in assisting general radiologists to differentiate between BI-RADS category 3 and 4 lesions.

ABSTRACT
Objective:To establish the predictive models for the prognosis of ductal carcinoma in situ (DCIS) at different pathological stages, and to evaluate the predictive performance of the models.Methods:Complete data of 273 patients with confirmed DCIS at different pathological stages who underwent mammography examination in Shenzhen People′s Hospital, Peking University Shenzhen Hospital and Shenzhen Luohu People′s Hospital from November 2014 to December 2020 were retrospectively collected, including 110 cases in the DCIS+ductal carcinoma in situ with microinvasion (DCIS-MI) group and 163 cases in the invasive ductal carcinoma (IDC)-DCIS group. The clinical, imaging and pathological features were analyzed. Mammary Mammo AI fusion model and deep learning-based natural language processing (NLP) structured diagnostic report model were used for image feature extraction. Patients in each group were randomly divided into training set and validation set with a ratio of 6∶4, and the predictors were screened by univariate and multivariate logistic regression analysis. The lowest Akaike information criterion value of each group was selected to construct the final predictive model. The receiver operating characteristic (ROC) curve was drawn to evaluate the performance of each model.Results:Taking estrogen receptor (-) or human epidermal growth factor receptor 2 (3+) as the poor prognostic reference, there were 62 cases considered with poor prognosis and 48 cases with good prognosis in DCIS+DCIS-MI group; while in the IDC-DCIS group, taking the Nottingham prognostic index as the reference, 33 cases were considered with poor prognosis, 73 cases with moderate prognosis, and 57 cases with good prognosis. Four predictive factors were screened to construct the DCIS+DCIS-MI-group predictive model, including DCIS nuclear grade, calcification with suspicious morphology in mammography, DCIS pathologic subtype and DCIS with microinvasion. Five predictive factors were screened to construct the IDC-DCIS-group predictive model, including neural or vascular invasion, Ki67 level, DCIS subtype, DCIS component proportion and associated features in mammography. The area under curve (AUC) for predicting poor prognosis of DCIS+DCIS-MI was 0.92 (95%CI 0.84-1.00) in the training set and 0.90 (95%CI 0.82-0.99) in the validation set; while the AUC for predicting poor prognosis of IDC-DCIS was 0.84 (95%CI 0.76-0.93) in the training set and 0.78 (95%CI 0.64-0.91) in the validation set.Conclusion:The developed models based on deep learning combined with NLP can effectively predict the prognosis of DCIS at different pathological stages, which are beneficial to the risk stratification of patients with DCIS, providing a reference for clinical decision.

Methods Laboratory-cultured D. farinae was collected, and the composition of microbial communities was determined by sequence analyses of the V4 region in the bacterial 16S ribosomal RNA (16S rRNA) gene on an Illumina PE250 high-throughput sequencing platform. Following quality control and filtering of the raw sequence files, valid reads were obtained and subjected to operational taxonomic units (OTU) clustering and analysis of the composition of microbial communities and alpha diversity index using the Usearch software, Silva database, and Mothur software. Results A total of 187 616 valid reads were obtained, and 469 OTUs were clustered based on a sequence similarity of more than 97%. OTU annotation showed that the bacteria in D. farinae belonged to 26 phyla, 43 classes, 100 orders, 167 families and 284 genera. The bacteria in D. farinae were mainly annotated to five phyla of Proteobacteria, Firmicutes, Bacteroidota, Actinobacteriota, and Acidobacteriota, with Proteobacteria as the dominant phylum, and mainly annotated to five dominant genera of Ralstonia, norank-f-Mitochondria, Staphylococcus and Sphingomonas, with Wolbachia identified in the non-dominant genus. Conclusions A high diversity is identified in the composition of the bacterial community in D. farinae, and there are differences in bacterial community diversity and abundance among D. farinae.
ABSTRACT
@#Objective To explore whether surgery combined with adjuvant chemotherapy can bring survival benefits to patients with cervical and upper thoracic esophageal squamous cell carcinoma (ESCC). Methods The clinical data of patients with cervical and upper thoracic ESCC who underwent R0 resection and neck anastomosis in our department from 2006 to 2010 were retrospectively analyzed. Patients received neoadjuvant therapy or adjuvant radiotherapy were excluded. The adjuvant chemotherapy group was given a combination of taxanes and platinum based chemotherapy after surgery; the surgery alone group did not receive adjuvant chemotherapy. The Kaplan-Meier method was used to analyze the survival difference between the adjuvant chemotherapy group and the surgery alone group. Results A total of 181 patients were enrolled, including 141 (77.9%) males and 40 (22.1%) females, with an average age of 61.0±8.2 years (80 patients aged≤61 years, 101 patients aged>61 years). There were 70 (38.7%) patients of cervical ESCC, and 111 (61.3%) patients of upper thoracic ESCC. Eighty-seven (48.1%) patients underwent postoperative adjuvant chemotherapy, and 94 (51.9%) patients underwent surgery alone, and the basic clinical characteristics were well balanced between the two groups (P>0.05). The median survival time of patients in the adjuvant chemotherapy group and the surgery alone group was 31.93 months and 26.07 months, and the 5-year survival rate was 35.0% and 32.0%, respectively (P=0.227). There was no statistical difference in median survival time between the cervical ESCC and upper thoracic ESCC group (31.83 months vs. 29.76 months, P=0.763). For cervical ESCC patients, the median survival time was 45.07 months in the adjuvant chemotherapy group and 14.70 months in the surgery alone group (P=0.074). Further analysis showed that the median survival time of lymph node negative group was 32.53 months, and the lymph node positive group was 24.57 months (P=0.356). The median survival time was 30.43 months in the lymph-node positive group with adjuvant chemotherapy and 17.77 months in the lymph-node positive group with surgery alone. The survival curve showed a trend of difference, but the difference was not statistically significant (P=0.557). Conclusion There is no statistical difference in the long-term survival of cervical and upper thoracic ESCC patients after R0 resection. Postoperative adjuvant chemotherapy may have survival benefits for patients with cervical ESCC and upper ESCC with postoperative positive lymph nodes, but the differences are not statistically significant in this setting.
ABSTRACT
Skin and soft tissue expansion can provide skin tissue similar to the recipient area in color and texture, which is one of the ideal methods in the repair of superficial defects. However, due to the long treatment cycle and relatively high complications rate in pediatric patients, expansion still faces many challenges. Based on the clinical practice and the current progress in skin and soft tissue expansion, this paper briefly discusses the change of skin after expansion, and the application, prevention and treatment of complications in the application of expansion in pediatric patients, aiming to provide reference for expansion in pediatric patients.

Objective:To determine the epidemiology of hyperkalemia and influencing factors in a general population in Pinggu district of Beijing city.Methods:This study was a cross-sectional survey. The subjects were from the epidemiological survey population of chronic diseases in Pinggu district of Beijing city from March to May 2014. All participants completed a questionnaire, anthropological measurement, and venous blood samples collection to detect serum creatinine and potassium and so on. First void morning urine was collected to detect the albumin-creatinine ratio. Hyperkalemia and hypokalemia were defined as serum potassium level>5.0 mmol/L and≤3.5 mmol/L, respectively. Logistic regression analysis method was used to analyze the influencing factors of hyperkalemia.Results:Of the 10 252 people in this study, the prevalence of hyperkalemia was 6.17%(95% CI 5.70%-6.67%), the prevalence of hypokalemia was 0.61%(95% CI 0.47%-0.79%), and the prevalence of participants with serum potassium>5.5 mmol/L was 0.53%(95% CI 0.40%-0.69%). Multivariate logistic regression analysis results showed that males ( OR=1.269, 95% CI 1.074-1.498, P=0.005), diabetes ( OR=1.226, 95% CI 1.008-1.490, P=0.041), increased total cholesterol ( OR=1.219, 95% CI 1.119-1.329, P<0.001), and decreased estimated glomerular filtration rate ( OR=0.971, 95% CI 0.965-0.977, P<0.001) were significantly correlated with the increased risk of hyperkalemia. Usage of renin-angiotensin-aldosterone system inhibitors and diuretics were not found to be significantly associated with the risk of hyperkalemia ( OR=1.018, 95% CI 0.751-1.380, P=0.908; OR=0.638, 95% CI 0.229-1.781, P=0.391). Conclusions:The prevalence of HK in the general population is 6.17%. The male, decreased estimated glomerular filtration rate, diabetes, and increased total cholesterol are influencing factors of hyperkalemia.
ABSTRACT
Objective:To analyze the clinical and pathological characteristics, treatment and prognosis of renal changes in patients with Kimura disease and improve the clinicians′ understanding on renal manifestations of Kimura disease.Methods:The clinical data of Kimura disease patients with definite diagnosis and detailed data in Peking Union Medical College Hospital from January 1980 to August 2020 were retrospectively analyzed. The patients were divided into renal impairment group and non-renal impairment group according to whether the kidney was involved or not and the related clinical data between the two groups were compared. The patients presenting with nephrotic syndrome were followed up.Results:There were 60 patients with Kimura disease confirmed by pathological diagnosis with 48 males. The median age was 33(3, 62) years old, and the median duration was 36(12, 111) months. There were 18 cases complicated with renal injury in 49 patients with complete routine urine and renal function examination and the main manifestations of renal injury were proteinuria and/or microscopic hematuria. There was no significant difference at age, sex and absolute value of eosinophils between the two groups (all P>0.05). Compared with the renal inpairment group, patients in non-renal inpairment group had longer course of disease, higher levels of hypersensitive C-reactive protein and erythrocyte sedimentation rate, and lower median values of total eosinophils and total IgE, but there was no statistically significant difference (all P>0.05). Among the patients with renal involvement, 6 patients met the diagnostic criteria for nephrotic syndrome, and 5 of them completed renal biopsies. The renal pathological diagnosis was membranous nephropathy in 2 cases and minimal change disease in 3 cases, and no interstitial eosinophil infiltration was found in renal biopsy tissues. These patients had a good response to glucocorticoids and/or immunosuppressive therapy, and achieved complete remission of nephrotic syndrome; at the same time, lymphadenopathy caused by Kimura disease could be well controlled. Conclusions:Kimura disease can combine with various renal lesions, and the pathology of nephrotic syndrome can be membranous nephropathy or minimal change nephropathy. After energetic treatment of glucocorticoids and/or immunosuppressive therapy, nephrotic syndrome can be completely relieved, and lymphadenopathy can be well controlled. The relationship between Kimura disease and renal disease needs further study.
ABSTRACT
Objective:To investigate the value of 18F-FDG PET/CT metabolic parameters in predicting perineural invasion (PNI) in patients with non-metastatic rectal cancer. Methods:From August 2012 to April 2020, 81 patients (51 males, 30 females, median age: 63 years) who received PET/CT examination and pathologically confirmed as rectal cancer in the Affiliated Hospital of Qingdao University were retrospectively analyzed. The 18F-FDG PET/CT metabolic parameters including SUV max, metabolic tumor volume (MTV) and total lesion glycolysis (TLG), and clinicopathological factors including gender, age, carcinoembryonic antigen (CEA), carbohydrate antigen (CA)19-9, maximum tumor diameter, degree of differentiation, T stage, lymph node metastasis, and TNM stage were recorded. Mann-Whitney U test and χ2 test were used to compare the differences of each parameter between PNI positive group and PNI negative group. Multivariate logistic regression was used to analyze the independent predictor of positive PNI. ROC curve was used to analyze its predictive efficacy. Results:Of 81 patients, 32(39.51%) were PNI positive and 49(60.49%) were PNI negative. There were significant differences of T stage ( χ2=10.73, P=0.010), lymph node metastasis ( χ2=6.21, P=0.013), TNM stage ( χ2=7.61, P=0.022), MTV (14.6(10.4, 24.7)and 9.0(5.4, 14.5) cm 3; U=-3.48, P=0.001) and TLG (108.588(72.749, 182.707) and 65.365(35.593, 117.682) g; U=-2.79, P=0.005) between PNI positive group and PNI negative group. Multivariate logistic regression analysis showed that MTV was the independent predictor of positive PNI in non-metastatic rectal cancer patients (odds ratio ( OR)=1.130, 95% CI: 1.025-1.245, P=0.014). The optimal threshold of MTV was 9.53 cm 3 and AUC was 0.73 with the sensitivity of 81.82%(27/33) and the specificity of 59.18%(29/49). Conclusion:18F-FDG PET/CT metabolic parameter MTV can predict PNI in non-metastatic rectal cancer with high sensitivity.
ABSTRACT
Objective:To explore the clinical features and risk factors of systemic lupus erythematosus(SLE) concomitant with interstitial lung disease(ILD) in children.Methods:A retrospective analysis was performed.A total of 111 hospitalized children diagnosed with SLE in the Department of Rheumatology and Immunology, Children′s Hospital of Soochow University from February 2016 to November 2018 were selected as the research subjects and divided into the SLE-ILD group(18 cases) and the SLE-non-ILD group(93 cases)according to the lung high-resolution CT manifestations.

Results:The prevalence of SLE-ILD was 16.2%(18/111 cases). There were significant differences between the SLE-ILD group and the SLE-non-ILD group in the course of disease [14.00 (12.00-24.25) months vs.1.00(1.00-2.00) months], the incidence of serositis [55.6%(10/18 cases) vs.8.6%(8/93 cases)], post-activity shortness of breath [83.3%(15/18 cases) vs.25.8%(24/93 cases)], nervous system damage [27.8%(5/18 cases) vs.6.5%(6/93 cases)], cardiovascular system damage [38.9%(7/18 cases) vs.9.7%(9/93 cases)], the occu-rrence of increased erythrocyte sedimentation rate [66.7%(12/18 cases) vs.31.2%(29/93 cases)], the decreased C 3[88.9%(16/18 cases) vs.62.4%(58/93 cases)], positive anti neutrophil cytoplasmic antibody (ANCA) [88.9%(16/18 cases) vs.18.3%(17/93 cases)], positive anti-Sm antibody [61.1%(11/18 cases) vs.15.1%(14/93 cases)] and anti ribonucleoprotein antibody (anti RNP antibody)[66.7%(12/18 cases) vs.16.1%(15/93 cases)](all P<0.05). Logistic regression analysis demonstrated that serositis( OR=30.535, 95% CI: 2.167-430.336, P=0.011), shortness of breath after exercise( OR=55.115, 95% CI: 1.117-2 579.852, P=0.041), positive ANCA( OR=65.090, 95% CI: 4.488-944.071, P=0.002) and positive anti-RNP antibody( OR=10.007, 95% CI: 1.362-73.500, P=0.024) were risk factors for SLE-ILD. Conclusions:The longer the course of SLE, the higher the incidence of ILD; serositis, shortness of breath after exercise, positive ANCA and positive anti RNP antibody may be risk factors for SLE-ILD.
ABSTRACT
OBJECTIVE@#To compare the clinical efficacy between Jiao's scalp acupuncture combined with virtual reality (VR) rehabilitation training and VR rehabilitation training alone for motor dysfunction in patients with Parkinson's disease (PD).@*METHODS@#A total of 52 patients with PD were randomly divided into an observation group and a control group, 26 cases in each group. The patients in both groups were treated with routine basic treatment, and the patients in the control group were treated with VR rehabilitation training. The patients in the observation group were treated with Jiao's scalp acupuncture on the basis of the control group. The scalp points included the movement area, balance area and dance tremor control area. Both groups were treated once a day, 5 times a week for a total of 8 weeks. Before treatment and 4 and 8 weeks into treatment, the gait parameters (step distance, step width, step speed and step frequency), timed "up and go" test (TUGT) time and unified Parkinson's disease rating scale part Ⅲ (UPDRS-Ⅲ) score were compared between the two groups, and the clinical efficacy was evaluated.@*RESULTS@#Four weeks into treatment, except for the step width in the control group, the gait parameters of the two groups were improved, the TUGT time was shortened, and the UPDRS-Ⅲ scores were reduced (P<0.01, P<0.05); the step distance in the observation group was better than that in the control group, and the UPDRS-Ⅲ score in the observation group was lower than that in the control group (P<0.05). Eight weeks into treatment, the gait parameters of the two groups were improved, the TUGT time was shortened, and the UPDRS-Ⅲ scores were reduced (P<0.01); the step distance and step speed in the observation group were better than those in the control group, the TUGT time in the observation group was shorter than that in the control group, and the UPDRS-Ⅲ score in the observation group was lower than that in the control group (P<0.05, P<0.01). The total effective rate was 92.3% (24/26) in the observation group, which was higher than 69.2% (18/26) in the control group (P<0.05).@*CONCLUSION@#Jiao's scalp acupuncture combined with VR rehabilitation training could improve the gait parameters, walking ability and motor function in patients with PD. The clinical effect is better than VR rehabilitation training alone.
