Objective:To investigate the diagnostic value of 11C-Pittsburgh compound B (PIB) in patients with mild cognitive impairment (MCI) and Alzheimer′s disease (AD) and explore the factors that may affect the binding of 11C-PIB. Methods:From January 2017 to December 2019, the 11C-PIB uptake of 6 patients with normal cognitive (NC; 3 males, 3 females, age: (64.5±12.3) years), 11 patients with MCI (4 males, 7 females, age: (64.5±9.8) years) and 21 patients with AD (7 males, 14 females, age: (68.1±9.1) years) from Daping Hospital, Army Medical University were retrospectively analyzed. Regional 11C-PIB binding was assessed by using standardized uptake value ratio (SUVR) and visual reading of 11C-PIB scan. Clinical data, including age, gender, education level, cognitive impairment, neuropsychological scale score, vascular risk factors (VRF), apolipoprotein E (ApoE) gene, were collected and differences among groups were analyzed by using one-way analysis of variance, least significant difference t test or Fisher exact test. Factors that affected the 11C-PIB binding were analyzed by multiple linear regression. Results:SUVR of cerebral lobe among NC, MCI and AD groups were significantly different (range of mean SUVR: 1.16-1.26, 1.19-1.35 and 1.40-1.61; F values: 5.331-9.279, all P<0.05). For positive PIB patients, SUVR of posterior cingulate and precuneus were increased in MCI group compared with NC group (1.20±0.15 vs 1.50±0.12, 1.18±0.15 vs 1.59±0.13; F values: 6.389 and 10.668, t values: -2.33 and -3.10, both P<0.05), and there were no significant differences in all lobes between MCI and AD group ( t values: from -1.29 to -0.51, all P>0.05). Visual analysis showed that the positive rates of PIB in frontal lobe (85.7%(18/21)), posterior cingulate (85.7%(18/21)), precuneus (81.0%(17/21)), temporal lobe (81.0%(17/21)) and occipital lobe (47.6%(10/21)) in AD were higher than those in MCI (4/11, 4/11, 4/11, 3/11 and 1/11, respectively; all P<0.05). Multiple linear regression showed that the degree of cognitive impairment were independent risk factors for SUVR of all lobes ( b values: 0.377-0.536, all P<0.05). The ApoE ε4 gene was independent risk factor for SUVR of precuneus ( b=0.290, P<0.05). Conclusion:11C-PIB is helpful for clinical diagnosis of MCI and AD patients and the degree of cognitive impairment and ApoE ε4 gene may be independent risk factors for increasing 11C-PIB binding.

Journal of Shanghai Jiaotong University(Medical Science) 2018;38(4):369-373
Objective: To study the expression of transcription factor BTB and CNC homology 2 (Bach2) in CD4+CD25+CD45RA- T cells from patients with systemic lupus erythematosus (SLE) and its effect on cell function. Methods: The CD4+CD25+CD45RA- T cells from active SLE patients and healthy volunteers were sorted by flow cytometry. The expression of Bach2 in CD4+CD25+CD45RA- T cells was detected by fluorescence quantitative PCR and Western blotting. The correlation between the median flourscence indensity (MFI) of Bach2 in CD4+CD25+CD45RA- T cells and the disease activity index of SLE (SLEDAI) was analyzed. The MFI of Bach2 in IL-17+CD4+CD25+CD45RA- T cells was compared with that in IL-17-CD4+CD25+CD45RA- T cells by flow cytometry. In Bach2 overexpression system, the expression of IL-17 in CD4+CD25+CD45RA- T cells was detected by flow cytometry and the concentration of IL-17 in the culture supernants was detected by ELISA. Results: The mRNA and protein expressions of Bach2 in CD4+CD25+CD45RA- T cells from SLE patients were significantly lower than those in healthy controls (P<0.01). There was a significant negative correlation between the MFI of Bach2 and SLEDAI (R2=0.433, P=0.001) in patients with SLE. The expression of Bach2 in IL-17+CD4+CD25+CD45RA- T cells was significantly lower than that in IL-17-CD4+CD25+CD45RA- T cells (P=0.013). When Bach2 was overexpressed, the percentage of CD4+CD25+CD45RA- T cells from SLE patients expressing inflammatory factor IL-17 decreased significantly (P=0.032) and the IL-17 concentration in cell culture supernatants markedly decreased (P=0.008). Conclusion: The expression of Bach2 in CD4+CD25+CD45RA- T cells from SLE patients decreases, and overexpression of Bach2 in the cells leads to the falling expression of IL-17.
7. Prognostic analysis and bilateral bleeding risk factor analysis of chronic subdural hematoma
Journal of Shanghai Jiaotong University(Medical Science) 2018;38(4):435-438
Objective: To analyse the relating factors that influence the prognosis of chronic subdural hematoma(CSDH) after drilling drainage and to explore the bilateral bleeding risk factors of CSDH. Methods: Four hundred and forty patients with CSDH who underwent drilling drainage were retrospectively analysed. Clinical data, including medical history, signs, blood coagulation function and imaging examination were collected. Spearman correlation analysis and ordinal Logistic regression analysis were performed to assess the relationships between various variables and the prognosis, and univariate analysis and multivariate Logistic regression analysis were performed to explore the risk factors that lead to the occurrence of bilateral bleeding. Results: Spearman correlation analysis indicated that age, medication history of anticoagulant drugs, bilateral hematoma or not, the thickness of the hematoma and volume of intracranial gas on the first post-surgery day and preoperative Markwalder grade were associated with postoperative Markwalder grade (P<0.05). Ordinal Logistic regression analysis showed that medication history of anticoagulant drugs and preoperative Markwalder grade were the independent risk factors (P=0.028, P=0.000). Univariate analysis of the bilateral bleeding indicated that age, medication history of anticoagulant drugs and thrombin time were statistically different between unilateral and bilateral CSDH (P<0.05). Multivariate Logistic regression analysis revealed that thrombin time was the independent risk factor (OR=1.147, 95%CI 1.005-1.309, P=0.042). Conclusion: Age and medication history of anticoagulant drugs were closely related to the bilateral chronic subdural hematoma. The higher the preoperative Markwalder grade is, the higher the postoperative Markwalder grade is. The prognosis of patients without anticoagulant drugs is better than those users.

Methods:
From September 3, 2018, to March 23, 2024, participants with essential hypertension (receiving antihypertensive medication treatment, hypertension group) and normal blood pressure (control group) were recruited from the Cardiology Department of Shanghai Hospital of Traditional Chinese Medicine, the Coronary Care Unit of Shanghai Tenth People's Hospital, the Physical Examination Center of Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine, and the Gaohang Community Health Service Center. This study employed the propensity score matching (PSM) method to reduce study participants selection bias. Spectral information in the facial visible light spectrum of the subjects was collected using a flame spectrometer, and the spectral chromaticity values were calculated using the equal-interval wavelength method. The study analyzed the differences in spectral reflectance across various facial regions, including the entire face, forehead, glabella, nose, jaw, left and right zygomatic regions, left and right cheek regions as well as differences in parameters within the Lab color space between the two subject groups. Feature selection was conducted using least absolute shrinkage and selection operator (LASSO) regression, followed by the application of various machine learning algorithms, including logistic regression (LR), support vector machine (SVM), random forest (RF), Naïve Bayes (NB), and eXtreme Gradient Boosting (XGB). The reduced-dimensional dataset was split in a 7 : 3 ratio to establish a classification and assessment model for facial coloration related to primary hypertension. Additionally, model fusion techniques were applied to enhance the predictive power. The performance of the models was evaluated using metrics including the area under the curve (AUC) and accuracy. Shapley Additive exPlanations (SHAP) was used to interpret the outcomes of the models.
Results:
A total of 114 participants were included in both hypertension and control groups. Reflectance analysis across the entire face and eight predefined areas revealed that the hypertensive group exhibited significantly higher reflectance of corresponding color light in the blue-violet region (P < 0.05) and a lower reflectance in the red region (P < 0.05) compared with control group. Analysis of Lab color space parameters across the entire face and eight predefined areas showed that hypertensive group had significantly lower a and b values than control group (P < 0.05). LASSO regression analysis identified a total of 18 facial color features that were highly correlated with hypertension, including the a values of the chin and the right cheek, the reflectance at 380 nm and at 780 nm of the forehead. The results of the multi-model classification showed that the RF classification model was the most effective, with an AUC of 0.74 and an accuracy of 0.77. The combined model of RF + LR + SVM outperformed a single model in their classification performance, achieving an AUC of 0.80 and an accuracy of 0.76. SHAP model visualization results indicated that the top three contributors to ideal prediction results based on the characteristics from the facial spectrum were the reflectance at 380 nm across the entire face and of the nose as well as the a value of the chin.
Conclusion
Within the same age group, patients with essential hypertension exhibited significant and regular changes in facial color and facial spectral reflectance parameters after the administration of antihypertensive drugs. Furthermore, facial reflectance indicators, such as the overall reflectance at 380 nm and the a value of the chin, could offer valuable references for clinically assessing the drug efficacy and health status of patients with essential hypertension.

This study focused on the intestinal absorption of traditional Chinese medicines (TCM) to reveal the scientific connotation of the compatibility of TCM pairs. The single pass intestinal perfusion (SPIP) was used in rats to compare the absorption of single extracts from Puerariae Lobatae Radix, single extracts from Ginseng Radix et Rhizoma, combined extracts from Puerariae Lobatae Radix and Ginseng Radix et Rhizoma and Puerariae Lobatae Radix and Ginseng Radix et Rhizoma mixture in rats. The content of puerarin, ginsenoside Rg1, ginsenoside Re and ginsenoside Rb1 in liquid were tested by HPLC. The speed constant (Ka) and apparent permeability coefficients (Papp) were calculated and compared. Specifically, the order of puerarin Ka and Papp values from high to low was Ginseng Radix et Rhizoma and Puerariae Lobatae Radix mixture > single extracts from Puerariae Lobatae Radix > combined extracts from Ginseng Radix et Rhizoma and Puerariae Lobatae Radix; the order of ginsenosides Ka and Papp values from high to low was Ginseng Radix et Rhizoma and Puerariae Lobatae Radix mixture > single extracts from Ginseng Radix et Rhizoma > combined extracts from Ginseng Radix et Rhizoma and Puerariae Lobatae Radix. The combined administration of Ginseng Radix et Rhizoma and Puerariae Lobatae Radix may improve the absorption in the intestinal tract.

OBJECTIVETo investigate the accumulation of advanced glycation end products (AGE) and the inflammatory response of skin and wound in diabetic patients, and to analyze their relationship in vitro.
METHODSHistological staining and immunohistochemical staining was respectively performed on skin and wound tissue specimens collected from 10 patients with Type II diabetes mellitus (diabetes group) and 12 non-diabetic patients with skin injury (control group) to observe the arrangement of collagen and the distribution of inflammatory cells, and to determine the expression levels of AGE and its receptor (RAGE). Malondialdehyde (MDA) levels in skin and wound tissue homogenates were assayed by enzyme-linked immunosorbent assay. In vitro, human neutrophils were isolated and treated with RPMI-1640 culture medium or that containing AGE-human serum albumin in the concentration of 0.315, 0.625, 1.250 mg/mL, and they were identified as normal control (NC) group, low concentration (L) group, moderate concentration (M) group, and high concentration (H) group. Cell viability in each group was determined by MTT colorimetric assay, and the reactive oxygen species (ROS) in cell was measured with 2', 7'-dichlorofluorescein-diacetate. Data were processed with t test.
RESULTSCompared with those of skin in control group, collagens of skin tissues in diabetes group atrophied and disorderly arranged. Inflammatory cells in wounds in diabetes group were dispersed, in which collagens arranged loosely and irregularly, as compared with those of wounds in control group. Expression levels of AGE and RAGE of skin in diabetes group were higher than those in control group. In diabetes and control groups, especially in diabetes group, the numbers of RAGE-positive cells in wound tissue were more than those in skin tissue. Large amount of inflammatory cells with positive expression of RAGE were observed in diabetes group. MDA level of skin and wound tissue in diabetes group was respectively (6.3 ± 1.0), (7.1 ± 2.4) nmol per milligram protein, which were obviously higher than those in control group [(2.9 ± 1.0), (3.6 ± 1.4) nmol per milligram protein, with t value respectively 8.017, 4.349, P < 0.05 or P < 0.01]. Cell viability and ROS levels in neutrophils were increased in L, M, and H groups [(59 ± 8)%, (77 ± 5)%, (67 ± 6)% and 1.67 ± 0.14, 2.13 ± 0.17, 3.48 ± 0.48] as compared with those in NC group [(34 ± 5)% and 0.58 ± 0.06, with t value respectively 7.195, 14.890, 11.130 and 20.195, 24.905, 16.864, P < 0.05 or P < 0.01].
CONCLUSIONSAbnormal oxidative stress in diabetic skin leads to an atypical origin of wound repair. AGE-RAGE effect is a critical mediator for oxidative stress in diabetic wound tissue during wound healing.
