ABSTRACT

Objective:To summarize clinical features of Kaposi′s sarcoma with a single skin lesion as the initial manifestation, and to analyze causes of its misdiagnosis.Methods:Data were retrospectively collected from 12 patients with Kaposi′s sarcoma with a single skin lesion as the initial manifestation in the People′s Hospital of Xinjiang Uygur Autonomous Region from January 2020 to January 2022. Clinical and histopathological features and causes of misdiagnosis were analyzed.Results:Among the 12 patients, 10 were males and 2 were females; 9 were of Uyghur nationality, and 3 were of Kazakh nationality; their ages ranged from 20 to 76 years, and 10 patients were aged ≥ 60 years. Skin lesions were mostly located on the feet (8 cases), including the lateral edge of the foot (3 cases), the sole of the foot (2 cases), the ankle (1 case), the dorsal side of the third toe (1 case), and the interdigital regions between the third and fourth toes (1 case) ; skin lesions were also observed on the fibular side of the right lower limb (2 cases), on the right side of the dorsal tongue (1 case), and on the dorsal side of the right little finger (1 case). The skin lesions manifested as purple-red nodules in 9 cases, dark-red nodules in 2 cases, and purple-red plaques in 1 case, with maximum diameters of 0.5 - 3.0 (1.9 ± 0.83) cm. Skin lesions were accompanied by pain in 6 cases and by pruritus in 1 case. Histopathologically, skin lesions manifested as the proliferation of vascular endothelial cells, which could form obvious vascular cavity, or presented as a large number of proliferative spindle cells depending on the degree of tumor differentiation; immunohistochemical study showed that all the 12 patients were positive for human herpes virus 8; immunohistochemical staining of CD34 and CD31 was performed in 11 and 4 patients respectively, all the 11 patients were positive for CD34, and all the 4 patients were positive for CD31. Among the 11 patients presenting with nodules, 6 were initially misdiagnosed with skin infection, 2 with hemangioma, 2 with cutaneous squamous cell carcinoma, and 1 with dermatofibroma; the 1 patient presenting with plaques was initially misdiagnosed with psoriasis; 8 patients were first diagnosed in the department of dermatology, 3 in the department of burns, and 1 was first diagnosed in the department of maxillofacial surgery.Conclusion:The Kaposi′s sarcoma initially manifesting as a single skin lesion was more common in males aged over 60 years, usually occurred on the feet, especially on the lateral edge of the foot, and mainly manifested as purple-red nodules; half of the patients were accompanied by pain; it was frequently misdiagnosed as skin infection in clinical practice, but histopathological examination could be helpful for its differential diagnosis.

ABSTRACT

Objective:To explore the genetic etiology and clinical phenotype of Feingold syndrome due to chromosome 2p24.3p24.2 microdeletion.Methods:The clinical data of a child admitted to Henan Provincial People′s Hospital in November 2021 and diagnosed as Feingold syndrome type 1 (FGLDS1) associated with chromosome 2p24.3p24.2 microdeletion were collected. The clinical and genetic variation characteristics of the patient were summarized, and 10 patients with chromosome 2p microdeletion reported until November 2022 were reviewed.Results:The boy was 12 years and 5 months old. He presented with backward physical development, motor development retardation, low intelligence, special body and facial appearance, finger developmental deformity and other manifestations, accompanied by hyperactivity and aggressive behavior, impulsive irritability, self-injury and other behavior problems. The proband showed normal chromosome karyotype; the genome-wide copy number variant sequencing and trio-whole exome sequencing revealed a 2.61 Mb deletion at chromosome 2p24.3p24.2 region, and 10 genes including MYCN gene (exons 1 to 3) in the deleted region.The same deletion was not found in either of his parents. The genetic features of 11 cases (including this case) with chromosome 2p microdeletion were summarized, all of whom had insufficient haploid dosage of the MYCN gene due to chromosome 2p microdeletion, and the clinical manifestations of these 11 patients matched the clinical diagnosis of FGLDS1. Conclusion:The proband is consistent with the clinical presentation of the typical Feingold syndrome, and the haploinsufficiency of the MYCN gene due to the microdeletion of chromosome 2 is the genetic etiology of the proband.

ABSTRACT

ObjectiveThis study aimed to improve the existing semen processing methods in the field of reproductive male medicine, particularly focusing on the 300 ×g 20 min treatment condition in the double-layer density gradient method, to enhance fertilization outcome. MethodsSemen specimens from 1 623 patients undergoing assisted reproductive techniques at the Reproductive Medicine Center of the Sixth Affiliated Hospital of Sun Yat-sen University from July and September 2020 and March and May 2022 were collected for preliminary experiments. Four different double-layer density gradient methods (200 ×g 10 min, 200 ×g 20 min, 300 ×g 10 min, and 300 ×g 20 min) were compared for sperm DNA fragmentation rates and recovery rates after processing. Subsequently, the optimal method was selected as the new approach and compared with the current method in use (300 ×g 20 min double-layer gradient method) to assess any statistical differences in fertilization rates. Further optimization to a single-layer density gradient method was performed based on the new method and compared with the double-layer density gradient method to determine any statistical differences. Experimental conditions were strictly controlled for temperature, centrifugation speed, and duration, with the quantity and processing conditions of each sample recorded. ResultsAmong the four double-layer density gradient methods, the sperm DNA fragmentation rate was lower with the 300 ×g 10 min treatment compared to 300 ×g 20 min while ensuring sufficient sperm recovery rates. Consequently, the 300 ×g 10 min method was selected as the new approach for experimentation. Results indicated that the total fertilization rate and 2 pronuclei (2PN) fertilization rate with the new 300 ×g 10 min method were higher than with the 300 ×g 20 min method, the difference was statistically significant (P < 0.05). Although the cleavage rate with 300 ×g 10 min was slightly higher than 300 ×g 20 min, the difference was not statistically significant (P > 0.05). The total fertilization rate and 2PN fertilization rate were slightly higher with the single-layer density gradient method compared to the double-layer density gradient method, but the difference was not statistically significant (P > 0.05). The cleavage rate with the single-layer density gradient method was higher than the double-layer density gradient method, and the blastocyst formation rate is lower than that of the double-layer density gradient method, and the differences are statistically significant (P < 0.05). ConclusionThe 300 ×g 10 min double-layer density gradient method successfully improved total fertilization rates, 2PN fertilization rates, and cleavage rates compared to the existing 300 ×g 20 min method, while reducing the time required for semen optimization processing. Although the single-layer density gradient method improves the cleavage rate, and saves reagent costs and operation time, its blastocyst formation rate has decreased. These findings provide valuable guidance and insights for semen processing methods in the field of reproductive andrology.

ABSTRACT

Objective To analyze the trend of disease burden of gastric cancer in Chinese residents from 1990 to 2019 and to provide reference for the prevention and control of gastric cancer in China. Methods The crude incidence and crude mortality rates of gastric cancer in Chinese residents of different genders from 1990 to 2019 were calculated from the Global Burden of Disease Study (GBD) database, and the standardized incidence and mortality rates were calculated to describe the trend of incidence and mortality of gastric cancer in Chinese residents. Disability Adjusted Life year (DALY) and years lived with Disability (DALY) were used. YLD, years of life lost (YLL) and other indicators were used to analyze the age and gender distribution of the disease burden of gastric cancer in Chinese residents. Joinpoint regression model was used to analyze the trend of the disease burden of gastric cancer. Results From 1990 to 2019, the incidence and crude incidence of gastric cancer increased, while the standard incidence decreased. The number of deaths was on the rise, the crude mortality rate and the standard mortality rate were both decreased, the morbidity and mortality index values of male were higher than that of female. The average annual average of the standardized DALY rate and the standardized YLL rate in China decreased by 2.30% (AAPC= -2.30%, P < 0.001), while the trend of the standardized YLD rate was not statistically significant (P=1.000). The average annual decrease rate of standardized DALY rate, standardized YLD rate and standardized YLL rate for males was smaller than that for females. In 2019, the peak rates of normalization of disease burden indicators were mainly distributed in the 55-74 age group. Conclusion From 1990 to 2019, the disease burden of gastric cancer in China showed a downward trend, and males and middle-aged and elderly people were the key prevention and treatment groups.

ABSTRACT

Objective:To identify the anatomical landmarks with stable and consistent performance in both rigid and deformation registrations,and to investigate the feasibility that take them as the quantitative indexes for quantitative evaluation of multimodality image registration for pancreatic cancer in clinical practice. Methods:Twenty-five patients with pancreatic cancer were selected.Both the rigid and deformation registrations were performed between simulated CT and MRI T1-weighted images.Seven anatomical landmarks,which were left adrenal gland,portal vein,celiac trunk artery,superior mesenteric artery,lumbar vertebral body,inferior vena cava and abdominal aorta,were selected.The anatomical landmarks were marked on the simulated CT and the registered MRI,respectively.The distances between the geometric centers of each anatomical landmarks in two kinds of images were statistically analyzed.The Wilcoxon rank sum test was implemented to compare the differences between rigid and deformation registrations.In addition,the correlations between anatomical landmarks were analyzed as well. Results:The mean distances of centers for the seven anatomical markers under rigid registration ranged from 0.405 cm to 1.097 cm,while they ranged from 0.433 cm to 0.740 cm under deformation registration.There was no significant difference in the registration of anatomical markers between rigid and deformation registration,except the left adrenal gland.The registration differences of celiac trunk artery and abdominal aorta were of most stable in 25 patients.Correlation study showed that all anatomical markers except abdominal aorta and inferior vena cava were independent and significant. Conclusion:It is feasible to quantitatively evaluate the registration quality of multimodality image registration for pancreatic cancer by using anatomical landmarks.It is recommended to use celiac trunk artery and abdominal aorta as the anatomical markers in clinical procedure.They are both stable in rigid and deformation registration,and the correlation between them is low,with means they can be used as independent evaluation criteria.

ABSTRACT

ObjectiveTo observe the clinical efficacy of the Modified Tongmai Anshen Formula (通脉安神方加减, MTAF) in the treatment of stable angina pectoris (SAP) with sleep disorders. MethodsA total of 148 patients suffering from SAP with sleep disorder were included and randomly divided into control group and treatment group, with 74 patients in each group. The control group received conventional western medicine, and the treatment group additionally received MTAF (1 dose per day), both for 4 weeks. The changes in angina pectoris symptoms, traditional Chinese medicine (TCM) syndromes, sleep quality, quality of life, serological indicators including serum intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1), brain-derived nerve growth factor (BDNF) and tyrosine kinase receptor B (TrkB) were compared between groups before and after treatment, and the safety was evaluated. ResultsIn the treatment group and the control group, the total effective rates of TCM syndromes(82.43% vs 52.70%), angina pectoris (79.73% vs 64.86%) and sleep (89.19% vs 68.92%) showing significant difference (P<0.001). After treatment, the total TCM syndrome score, primary symptom score, secondary symptom score, and secondary symptoms sleeplessness, restlessness, tiredness and fatigue individual score, angina pectoris score, PSQI total score and each item score were all significantly reduced in both groups, while the SF-36 single item score significantly increased (P<0.05). The total TCM syndromes and primary symptom scores, secon-dary symptoms sleeplessness, restlessness, tiredness and fatigue individual score, angina pectoris score, time to fall asleep, sleep quality, hypnotic medication, sleep disturbance, daytime dysfunction score and PSQI total score were significantly lower in the treatment group than those in the control group after treatment (P<0.05), while the somatic pain, general health status, social functioning, emotional functioning, mental health, and health change were significantly higher in the treatment group (P<0.05). After treatment, ICAM-1 and VCAM-1 level significantly decreased (P<0.05), and BDNF and TrkB levels increased (P<0.05) in the treatment group, while BDNF level significantly decreased in the control group (P<0.05). The TrkB level was significantly higher in the treatment group compared to the control group after treatment (P<0.05). A total of four adverse events occurred during the treatment, none of which were considered to be related to this study. ConclusionMTAF can significantly improve angina pectoris symptoms, TCM syndromes, sleep quality and quality of life in patients suffering from SAP with sleep disorders, the mechanism of which may be related to the protection of vascular endothelial function and central neurons.

ABSTRACT

Objective:To explore the predictive value of transrectal multimodal ultrasound and prostate specific antigen (PSA) in clinically organ-confined prostate cancer.Methods:It was a cross-sectional study. The clinical data of patients with suspected prostate nodules treated in the First Hospital of Shanxi Medical University from May 2014 to April 2020 were analyzed retrospectively. Of the patients, 48 cases of clinically organ-confined prostate cancer and 51 cases of benign prostatic hyperplasia confirmed by clinical data and pathology were selected as research objects. The characteristics of transrectal multimodal ultrasound in the two groups were compared. Combined with PSA, logistic regression analysis was applied to screen the statistically significant features, and then the diagnosis model was established, and odds ratio of the variables were compared. The receiver operating characteristic (ROC) curve was constructed to analyze the predicting ability of the diagnosis model.Results:Four features were obtained with logistic regression analysis finally, including enhancement type, enhancement degree, elastography mode and PSA. The odds ratio of enhancement degree was higher than those of the other independent variables. The area under ROC curve of the diagnosis model was 0.868 ( P<0.01), the cut-off value was 0.514. The sensitivity and specificity of the diagnosis model in predicting clinically organ-confined prostate cancer was 79.2% and 80.4%, respectively. Conclusions:This combined diagnosis model of transrectal multimodal ultrasound and PSA has a certain clinical value in predicting clinically organ-confined prostate cancer.

ABSTRACT

Objective:To explore the relationship between metabolic score for insulin resistance (METS-IR) and chronic kidney disease (CKD) and albuminuria in the Chinese population.Methods:This cross-sectional study was conducted from January to December 2018 among residents aged 20 to 70 years in ten regions of eight provinces in China; all residents had lived in their region for more than 5 years. Various parameters were measured, included fasting blood glucose, 2-hour postprandial blood glucose, glycosylated hemoglobin (HbA 1c), blood lipids, renal function, urinary albumin/creatinine ratio (UACR), etc. Data of 5 060 subjects meeting the criteria were included in the study. CKD was defined as estimated glomerular filtration rate (eGFR)<60 ml·min -1·1.73 m -2 or UACR≥30 mg/g. Albuminuria was defined as UACR≥30 mg/g. METS-IR was calculated and categorized into quartiles: Q1, METS-IR≤32.19; Q2, METS-IR 32.20-37.10; Q3, METS-IR 37.11-42.58; and Q4, METS-IR>42.58. The correlation between METS-IR and CKD and albuminuria was analyzed by binary logistic regression, and subgroup analyses were performed. Results:There were 1 266, 1 266, 1 265, and 1 263 participants included in Q1-Q4 groups, respectively. With the increase of METS-IR quartile, various parameters increased, including age, fasting blood glucose, HbA 1c, triglycerides, serum uric acid, waist circumference, body mass index, and systolic and diastolic blood pressure, and the proportion of males also increased (all P<0.05). The proportion of patients with CKD and albuminuria increased significantly with the increase in interquartile range (Q) of METS-IR (all P<0.05). Logistic regression analysis showed that for every 1-unit increment of METS-IR, the risk of CKD and albuminuria were both increased by 2% [for both: odds ratio ( OR)=1.02, 95% confidence interval ( CI) 1.01-1.03]. Compared with the lowest METS-IR group (Q1), the ORs for CKD and albuminuria in the highest METS-IR group (Q4) were 1.57 (95% CI 1.17-2.10) and 1.46 (95% CI 1.09-1.96), respectively. In the subgroup analyses, increased METS-IR was significantly associated with CKD and albuminuria among women (CKD: OR=1.62, 95% CI 1.14-2.31; albuminuria: OR=1.53, 95% CI 1.07-2.18), individuals with HbA 1c<7% ( OR=1.64, 95% CI 1.21-2.23; OR=1.55, 95% CI 1.14-2.11), individuals with eGFR≥90 ml·min -1·1.73 m -2 ( OR=1.78, 95% CI 1.27-2.49; OR=1.80, 95% CI 1.28-2.53), and the Chinese Han population ( OR=1.56, 95% CI 1.13-2.17; OR=1.41, 95% CI 1.01-1.96). Conclusions:METS-IR is significantly associated with CKD and albuminuria in a Chinese population. Furthermore, the higher the METS-IR, the higher the risk of CKD and albuminuria.

ABSTRACT

Objective:To determine the expression of glucose transporter 3 (GLUT3) in cutaneous squamous cell carcinoma (cSCC), and to evaluate its effect on the cSCC cell line A431.Methods:From June 2016 to December 2020, 22 paraffin-embedded tissue specimens were collected from patients with pathologically confirmed cSCC in the Department of Dermatology, Peking University Third Hospital, and 20 discarded normal skin tissues after dermatological surgeries served as controls. Immunohistochemical assay was performed to determine the GLUT3 expression in cSCC tissues and normal skin tissues. Cultured A431 cells were divided into two groups: GLUT3 overexpression group transfected with a lentiviral vector carrying the SLC2A3 gene, and negative control group transfected with an empty lentiviral vector. Real-time fluorescence-based quantitative PCR and Western blot analysis were conducted to determine the mRNA and protein expression of GLUT3 in A431 cells in different groups, the cell proliferation assay (MTS assay) was performed to estimate the cell proliferative activity, and the live-cell analysis system Incucyte S3 was used for real-time evaluation of the migratory and invasive abilities of A431 cells in different groups. The relative glucose consumption and lactic acid production in A431 cells at 48 hours were measured by using glucose and lactic acid assay kits, retrospectively. Two independent samples t-test was used for comparisons between two groups, and one-way analysis of variance was used for comparisons among multiple groups. Results:The GLUT3 expression was significantly higher in the cSCC tissues than in the normal skin tissues (immunohistochemical assay score: 9.39 ± 2.56 points vs. 2.30 ± 2.60 points; t = 8.91, P < 0.05). Compared with the negative control group, the mRNA and protein expression of GLUT3 markedly increased in the GLUT3 overexpression group. MTS assay showed significantly increased proliferative activity of A431 cells in the GLUT3 overexpression group compared with the negative control group after 24- and 96-hour treatment ( t = 2.49, 3.54, P = 0.048, 0.012, respectively); cell fusion rates in the scratched area were significantly higher in the GLUT3 overexpression group than in the negative control group in the cell migration assay at 6, 12 18, and 24 hours and cell invasion assay at 12, 18, and 24 hours (all P < 0.05). At 48 hours, the relative glucose consumption and lactic acid production in A431 cells were significantly higher in the GLUT3 overexpression group than in the negative control group ( t = 2.98, 2.20, P = 0.011, 0.038, respectively) . Conclusion:GLUT3 was highly expressed in the cSCC tissues, and may participate in the occurrence and development of cSCC by providing energy to cSCC cells via promoting glucose uptake in cells to enhance their proliferative, migratory and invasive abilities.

In the electroencephalography (EEG) monitoring of patients with hypoxic-ischemic encephalopathy, generalized periodic discharges are often monitored abnormal waveforms. When there are some features of generalized periodic discharges (e.g., frequency≥1.5 Hz or plus), it indicates that the patient is at high risk for seizures or has a poor prognosis. Compared with conventional EEG, the time of continuous EEG monitoring is longer, so the detection rate of these waveforms is higher. At present, scholars at home and abroad have studied these waveforms, but there is controversy about the significance of these waveforms. In this paper, the definition and characteristics of these waveforms and their significance in determining prognosis and guiding treatment in patients with hypoxic-ischemic encephalopathy are reviewed.

ABSTRACT

Objective:To study the effect of cardiac rehabilitation program on recovery of patients after small incision aortic valve replacement.Methods:600 patients who underwent small incision aortic valve replacement in our hospital from January 2015 to January 2020 were retrospectively collected and divided into Cardiac rehabilitation group(CR) and control group by propensity matching analysis. Clinical data of CR group and control group were collected 6 months and 12 months after the beginning of Cardiac rehabilitation program. The primary outcome measures were the peak oxygen uptake(VO 2 Peak) of cardiopulmonary function test and the number of patients attending cardiovascular specialty in tertiary hospitals after the rehabilitation program began. The secondary outcome measures were 6-minute Walk test(6-MWT), psychological evaluation, and assessment of cardiovascular disease risk factors. Results:After 6 months and 12 months of cardiac rehabilitation program, the VO2 peak in CR group was statistically significant compared with the control group, and the 6-MWT index after 12 months was statistically significant.The cardiovascular specialist visits in tertiary hospitals in the two groups were statistically significant. The comparison of psychological self-rating scale and cardiovascular disease risk factors between the two groups was statistically significant after propensity matching analysis.Conclusion:Cardiac rehabilitation has a positive effect on postoperative recovery after small incision aortic valve replacement, and can improve patients’ motor ability.

ABSTRACT

Objective To establish a solvent desorption inductively coupled plasma-mass spectrometry (ICP-MS) method for determination of iodine in workplace air. Methods Iodine in workplace air was collected with alkaline activated carbon tube and desorbed with 10.0 mL pure water or 20 mmol/L sodium bicarbonate solution. Rhenium-185 was used as an internal standard for quantification. The sample was determined in standard mode and kinetic energy discrimination collision (KED) mode by ICP-MS. Results In standard mode, iodine showed a good linear range in the concentration of 9.0 to 1 100.0 μg/L, with a correlation coefficient of 0.999 3 and a detection limit of 2.7 μg/L. In KED mode, iodine showed a good linear range in the concentration of 24.3 to 800.0 μg/L, with a correlation coefficient of 0.999 1 and a detection limit of 7.3 μg/L. The average desorption efficiency using pure water ranged from 99.1% to 106.7%, with within-run relative standard deviation (RSD) of 3.1% to 8.0% and between-run RSD of 4.9% to 9.3%. The average desorption efficiency using sodium bicarbonate solution ranged from 96.5% to 105.3%, with within-run RSD of 4.9% to 8.6% and between-run RSD of 2.5% to 9.9%. There were no statistical significant differences in the main effects of desorption solution, ICP-MS detection mode, their interaction on average desorption efficiency and within-run RSD (all P>0.05). Samples could be stored at room temperature for at least 7 days. Conclusion This method is highly sensitive, accurate, and suitable for the determination of iodine in workplace air. The sample pretreatment is simple and rapid.
