Causal relationships between dietary habits and Barrett's esophagus risk: a univariable and multivariable Mendelian randomization study.

Aims: Dietary habits are reported to be associated with Barrett's esophagus (BE) risk; however, whether there is a causal relationship remains controversial. Here, we systematically examined the causal effects of genetically predicted dietary habits on BE risk through a Mendelian randomization (MR) analysis approach. Methods: Data for exposures were obtained from the UK Biobank (UKB), while the summary-level data for outcomes were obtained from a large sample-size GWAS meta-analysis. Genetic variants associated with 17 ordinary dietary habits at the genome-wide significance level were regarded as instrumental variables (IVs). Univariable and multivariable MR analyses were conducted to explore the causal relationships between dietary habits and BE risk. Sensitivity analyses were implemented to evaluate robustness of the results and determine the potential pleiotropy bias. Results: Univariable MR (UVMR) analysis showed that genetic predisposition to alcohol intake frequency, cooked vegetable intake, beef intake, bread intake, fresh fruit intake, salad/raw vegetable intake, and dried fruit intake were associated with BE risk, with all P values <0.05. After adjusting confounders, the effects of four dietary habits on BE risk persisted; multivariable MR (MVMR) analysis revealed that alcohol intake frequency (adjusted odds ratio (OR) = 1.74 (1.34, 2.27); P = 3.42 × 10-5) was causally associated with higher BE risk, the cooked vegetable intake (adjusted OR = 2.64 (1.16, 5.97); P = 0.02) had suggestively increased BE risk, while higher consumption of bread (adjusted OR = 0.54 (0.32-0.91); P = 0.02) and fresh fruit (adjusted OR = 0.34 (0.15, 0.77); P = 0.01) were suggestively associated with lower BE risk. Conclusions: These MR analyses demonstrate evidence of causal relationships between dietary habits and BE risk. These findings provide new insights into targeted dietary intervention strategies for BE prevention.

Brownfield redevelopment evaluation based on structure-process-outcome theory and continuous ordered weighted averaging operator-topology method.

As an important part of urban renewal, brownfield restoration and renovation are of great significance to the sustainable development of cities. The structure-process-outcome theory was introduced into this study to improve the rationality and scientific vigor of the redevelopment assessment process and to evaluate whether brownfield sites meet the conditions for redevelopment. Based on this theory, the relationship among structures, processes and outcomes can be well elucidated. Specifically, a good structure should contribute to an effective process, which will increase the possibility of a favorable outcome. The basic conditions, practice principles, and result orientation in the whole procedure of brownfield redevelopment were comprehensively analyzed. In addition, a more complete and reasonable three-level evaluation index system for brownfield redevelopment was established. In order to reduce the subjectivity in the evaluation process, an unbiased scientific brownfield redevelopment evaluation model was constructed using the continuous ordered weighted averaging operator-topology method. The evaluation decision system was applied to the renovation of a tract project in Chengdu, China. The results proved that the model could effectively and accurately evaluate the quality level of the brownfield redevelopment project, and the proposed recommendations can provide a basis for decision-making.

Regional homogeneity in patients with obsessive-compulsive disorder and depression: A resting state functional magnetic resonance imaging study.

OBJECTIVE: To explore the brain functional impairment of patients with obsessive-compulsive disorder (OCD) with and without depressive symptoms and analyze the correlation between the degree of impairment and the severity of symptoms. METHOD: Fourteen patients with OCD who met the ICD-10 diagnostic criteria for OCD were included. The group having OCD with depression (OCDd) consisted of 15 patients, and 17 healthy controls (HC) matched for age and education were also included. The Yale-Brown OCD Scale (Y-BOCS) and the 24-item Hamilton Assessment of Depression Scale (HAMD) were administered to the OCD and OCDd groups. Resting-state functional brain magnetic resonance imaging was performed in the three groups of participants. RESULT: The OCDd group had lower scores on the HAMD, Y-BOCS, and obsessive-compulsive thinking subscales compared with the OCD group (P < 0.05). The scores on the OCDd subscale were negatively correlated with the HAMD scores (R =  - 0.568, P = 0.027). The OCDd group had higher regional homogeneity (ReHo) values in the lingual gyrus than the OCD group. The OCDd group had higher ReHo values in the lingual gyrus than the HC group, and the OCDd group had higher ReHo values than the HC group. These differences were statistically significant (P < 0.05). After correction for multiple comparisons, significant difference was observed between the OCDd and HC groups (P＜0.05). In the OCD group, the ReHo value of the lingual gyrus was negatively correlated with the Y-BOCS total score and the compulsive behavior subscale score (R =  - 0.609, -0.552; P = 0.016, 0.033). CONCLUSION: Abnormal ReHo values in the lingual gyrus and right medial superior frontal gyrus were found in the patients with OCDd. In the OCDd group, the ReHo values of the lingual gyrus were negatively correlated with the scores on the Y-BOCS total and obsessive-compulsive subscales, suggesting that abnormal local coherence of the lingual gyrus may be related to the severity of OCD.

Prognostic potential of serum mesencephalic astrocyte-derived neurotrophic factor in acute intracerebral hemorrhage: a prospective observational study.

OBJECTIVE: Mesencephalic astrocyte-derived neurotrophic factor (MANF) expressions are dramatically up-regulated in injured brain tissues, thereby conferring neurological protective effects. We intended to determine significance of serum MANF as a prognostic biomarker of intracerebral hemorrhage (ICH). METHODS: In this prospective, observational study done from February 2018 to July 2021, 124 patients with new-onset primary supratentorial ICH were consecutively enrolled. Also, a group of 124 healthy individuals constituted controls. Their serum MANF levels were detected using the Enzyme-Linked Immunosorbent Assay. National Institutes of Health Stroke Scale (NIHSS) and hematoma volume were designated as the two severity indicators. Early neurologic deterioration (END) was referred to as an increase of 4 or greater points in NIHSS scores or death at post-stroke 24 h. Post-stroke 90-day modified Rankin scale (mRS) scores of 3-6 was considered as a poor prognosis. Serum MANF levels were analyzed using multivariate analysis with respect to its association with stroke severity and prognosis. RESULTS: Patients, in comparison to controls, displayed markedly elevated serum MANF levels (median, 24.7 versus 2.7 ng/ml; P < 0.001), and serum MANF levels were independently correlated with NIHSS scores (beta, 3.912; 95% confidence interval (CI), 1.623-6.200; VIF = 2.394; t = 3.385; P = 0.002), hematoma volumes (beta, 1.688; 95% CI, 0.764-2.612; VIF = 2.661; t = 3.617; P = 0.001) and mRS scores (beta, 0.018; 95% CI, 0.013-0.023; VIF = 1.984; t = 2.047; P = 0.043). Serum MANF levels significantly predicted END and poor 90-day prognosis with areas under receiver operating characteristic curve at 0.752 and 0.787 respectively. END and prognostic predictive abilities were similar between serum MANF levels and NIHSS scores plus hematoma volumes (all P > 0.05). Combination of serum MANF levels with NIHSS scores and hematoma volumes had significantly higher prognostic capability than each of them (both P < 0.05). Serum MANF levels above 52.5 ng/ml and 62.0 ng/ml distinguished development of END and poor prognosis respectively with median-high sensitivity and specificity values. Using multivariate analysis, serum MANF levels > 52.5 ng/ml predicted END with odds ratio (OR) value of 2.713 (95% CI, 1.004-7.330; P = 0.042) and > 62.0 ng/ml predicted a poor prognosis with OR value of 3.848 (95% CI, 1.193-12.417; P = 0.024). Using restricted cubic spline, there was a linear correlation between serum MANF levels and poor prognosis or END risk (both P > 0.05). Nomograms were well established to predict END and a poor 90-day prognosis. Under calibration curve, such combination models were comparatively stable (using Hosmer & Lemeshow test, both P > 0.05). CONCLUSION: Increased serum MANF levels after ICH, in independent correlation with disease severity, independently distinguished risks of END and 90-day poor prognosis. Therefore, serum MANF may be a potential prognostic biomarker of ICH.

Baveno-VII criteria to predict decompensation and initiate non-selective beta-blocker in compensated advanced chronic liver disease patients.

BACKGROUND/AIMS: The utility of Baveno-VII criteria of clinically significant portal hypertension (CSPH) to predict decompensation in compensated advanced chronic liver disease (cACLD) patient needs validation. We aim to validate the performance of CSPH criteria to predict the risk of decompensation in an international real-world cohort of cACLD patients. METHODS: cACLD patients were stratified into three categories (CSPH excluded, grey zone, and CSPH). The risks of decompensation across different CSPH categories were estimated using competing risk regression for clustered data, with death and hepatocellular carcinoma as competing events. The performance of "treating definite CSPH" strategy to prevent decompensation using non-selective beta-blocker (NSBB) was compared against other strategies in decision curve analysis. RESULTS: One thousand one hundred fifty-nine cACLD patients (36.8% had CSPH) were included; 7.2% experienced decompensation over a median follow-up of 40 months. Non-invasive assessment of CSPH predicts a 5-fold higher risk of liver decompensation in cACLD patients (subdistribution hazard ratio, 5.5; 95% confidence interval, 4.0-7.4). "Probable CSPH" is suboptimal to predict decompensation risk in cACLD patients. CSPH exclusion criteria reliably exclude cACLD patients at risk of decompensation, regardless of etiology. Among the grey zone, the decompensation risk was negligible among viral-related cACLD, but was substantially higher among the non-viral cACLD group. Decision curve analysis showed that "treating definite CSPH" strategy is superior to "treating all varices" or "treating probable CSPH" strategy to prevent decompensation using NSBB. CONCLUSION: Non-invasive assessment of CSPH may stratify decompensation risk and the need for NSBB in cACLD patients.

Spatial and temporal expression pattern of somatostatin receptor 2 in mouse / 生物工程学报

Somatostatin (SST) is an inhibitory polypeptide hormone that plays an important role in a variety of biological processes. Somatostatin receptor 2 (SSTR2) is the most widely expressed somatostatin receptor. However, the specific cell types expressing Sstr2 in the tissues have not been investigated. In this study, we detected the expression pattern of SSTR2 protein in mouse at different development stages, including the embryonic 15.5 days and the postnatal 1, 7, 15 days as well as 3 and 6 months, by multicolour immunofluorescence analyses. We found that Sstr2 was expressed in some specific cells types of several tissues, including the neuronal cells and astrocytes in the brain, the mesenchymal cells, the hematopoietic cells, the early hematopoietic stem cells, and the B cells in the bone marrow, the macrophages, the type Ⅱ alveolar epithelial cells, and the airway ciliated cells in the lung, the epithelial cells and the neuronal cells in the intestine, the hair follicle cells, the gastric epithelial cells, the hematopoietic stem cells and the nerve fibre in the spleen, and the tubular epithelial cells in the kidney. This study identified the specific cell types expressing Sstr2 in mouse at different developmental stages, providing new insights into the physiological function of SST and SSTR2 in several cell types.

Objective: To explore the safety and feasibility of gasless submental approach endoscopic removal of thyroglossal cyst. Methods: This work prospectively included the clinical data of 13 patients who underwent the gasless submental approach endoscopic removal of thyroglossal cyst at the Department of Otolaryngology, the First Affiliated Hospital of Chongqing Medical University from August 2021 to February 2022. The operative time, bleeding volumes, postoperative complications, subjective pain levels, satisfaction with incisional scars, neck and facial deformities, and recurrences were prospectively evaluated by visual analogue scale(VAS) score. Results: All of 13 patients were successfully treated using this new technique. The patients had a median age of 38 years, ranging from 24 to 59 years, comprising of 3 males and 10 females. The length of the submental incision was about 3 cm and the median of operation time was 135 minutes. Postoperative complications were minimal. The median volume of blood loss was 10 ml. Surgical site swelling existed in 1 case and dysphagia for more than 1 week occurred in 2 cases. Patients were discharged from the hospital with a median of 3 days after surgery. On a VAS of 0-10 scores, the pain had a median of 2 on the first day after surgery, and the satisfaction with incision scars and neck and facial deformities showed a median of 8 at 6 months after surgery. There were no recurrences during the follow-up period of 9-15 months. Conclusion: Gasless submental approach endoscopic removal of thyroglossal cyst may be a reliable new surgical method that is safe and has cosmetic advantages.

Clinical features and microsurgical reconstruction of congenital unilateral absence of the vas deferens with obstructive azoospermia: a tertiary care center experience / 亚洲男科学杂志(英文版)

Patients with congenital unilateral absence of the vas deferens (CUAVD) manifest diverse symptoms from normospermia to azoospermia. Treatment for CUAVD patients with obstructive azoospermia (OA) is complicated, and there is a lack of relevant reports. In this study, we describe the clinical features and evaluate the treatments and outcomes of CUAVD patients with OA. From December 2015 to December 2020, 33 patients were diagnosed as CUAVD with OA in Shanghai General Hospital (Shanghai, China). Patient information, ultrasound findings, semen analysis, hormone profiles, and treatment information were collected, and the clinical outcomes were evaluated. Of 33 patients, 29 patients were retrospectively analyzed. Vasoepididymostomy (VE) or cross VE was performed in 12 patients, the patency rate was 41.7% (5/12), and natural pregnancy was achieved in one of the patients. The other 17 patients underwent testicular sperm extraction as the distal vas deferens (contralateral side) was obstructed. These findings showed that VE or cross VE remains an alternative treatment for CUAVD patients with OA, even with a relatively low rate of patency and natural pregnancy.

Diagnostic value of a combined serology-based model for minimal hepatic encephalopathy in patients with compensated cirrhosis / 中华检验医学杂志

Objective:To investigate the diagnostic accuracy of serological indicators and evaluate the diagnostic value of a new established combined serological model on identifying the minimal hepatic encephalopathy (MHE) in patients with compensated cirrhosis.Methods:This prospective multicenter study enrolled 263 compensated cirrhotic patients from 23 hospitals in 15 provinces, autonomous regions and municipalities of China between October 2021 and August 2022. Clinical data and laboratory test results were collected, and the model for end-stage liver disease (MELD) score was calculated. Ammonia level was corrected to the upper limit of normal (AMM-ULN) by the baseline blood ammonia measurements/upper limit of the normal reference value. MHE was diagnosed by combined abnormal number connection test-A and abnormal digit symbol test as suggested by Guidelines on the management of hepatic encephalopathy in cirrhosis. The patients were randomly divided (7∶3) into training set ( n=185) and validation set ( n=78) based on caret package of R language. Logistic regression was used to establish a combined model of MHE diagnosis. The diagnostic performance was evaluated by the area under the curve (AUC) of receiver operating characteristic curve, Hosmer-Lemeshow test and calibration curve. The internal verification was carried out by the Bootstrap method ( n=200). AUC comparisons were achieved using the Delong test. Results:In the training set, prevalence of MHE was 37.8% (70/185). There were statistically significant differences in AMM-ULN, albumin, platelet, alkaline phosphatase, international normalized ratio, MELD score and education between non-MHE group and MHE group (all P<0.05). Multivariate Logistic regression analysis showed that AMM-ULN [odds ratio ( OR)=1.78, 95% confidence interval ( CI) 1.05-3.14, P=0.038] and MELD score ( OR=1.11, 95% CI 1.04-1.20, P=0.002) were independent risk factors for MHE, and the AUC for predicting MHE were 0.663, 0.625, respectively. Compared with the use of blood AMM-ULN and MELD score alone, the AUC of the combined model of AMM-ULN, MELD score and education exhibited better predictive performance in determining the presence of MHE was 0.755, the specificity and sensitivity was 85.2% and 55.7%, respectively. Hosmer-Lemeshow test and calibration curve showed that the model had good calibration ( P=0.733). The AUC for internal validation of the combined model for diagnosing MHE was 0.752. In the validation set, the AUC of the combined model for diagnosing MHE was 0.794, and Hosmer-Lemeshow test showed good calibration ( P=0.841). Conclusion:Use of the combined model including AMM-ULN, MELD score and education could improve the predictive efficiency of MHE among patients with compensated cirrhosis.

Update and interpretation of Elsevier clinical pathway for gastric, gastroesophageal junction and esophageal cancer ( Chinese edition, 2022) / 中华消化杂志

The standardized treatment of malignant tumor has always been the direction of continuous improvement of major medical institutions. In recent years, the basic research, prevention, screening and diagnosis and treatment level of gastric, gastroesophageal junction and esophageal cancer have been greatly improved, resulting in a significant improvement in the 5 years′ survival rate of patients, but there are still great differences in the diagnosis and treatment level among different regions. Chinese gastric cancer, gastroesophageal junction cancer and esophageal cancer differ greatly from European and American countries in etiology, pathological types, high incidence sites, etc. Therefore, the relevant guidelines of European and American countries cannot fully meet Chinese clinical practice. In 2021, Elsevier Publishing Group launched the Chinese edition of Elsevier clinical pathway for gastric, gastroesophageal junction and esophageal cancer, and the first update edition was made in 2022, which aims to promote the quality control of tumor diagnosis and treatment, standardize tumor diagnosis and treatment behaviors, promote the homogenization and standardization of tumor diagnosis and treatment, and ultimately improve the survival rate and quality of life of patients with malignant tumor. This pathway refers to the National Comprehensive Cancer Network clinical practice guidelines, the Chinese Society of Clinical Oncology guidelines, combines evidence-based medicine and clinical experience, and follows the scientific, universal, standardized and operable principles. It has been promoted and applied in clinical practice, and is constantly updated according to the latest research results.

Analysis on the risk factors and establishment of a prediction model for primary non-response to the treatment of anti-tumor necrosis factor-α monoclonal antibody in Crohn′s disease patients / 中华消化杂志

Objective:To investigate the risk factors and establish a prediction model of primary non-response (PNR) to anti-tumor necrosis factor-α(TNF-α) monoclonal antibody in Crohn′s disease (CD) patients.Methods:From December 1, 2018 to July 31, 2022, 103 patients with CD treated with the anti-TNF-α monoclonal antibody in Renmin Hospital of Wuhan University were enrolled (modeling group), and at the same time, 109 patients with CD treated with anti-TNF-α monoclonal antibody in Zhongnan Hospital of Wuhan University were selected (validation group). The baseline clinical data of all the patients before the first treatment of anti-TNF-α monoclonal antibody were collected, which included C-reactive protein (CRP), the simplified Crohn′s disease activity index (CDAI), and modified multiplier simple endoscopic score for Crohn′s disease (MM-SES-CD), etc. Multivariate logistic regression was used to screen the independent risk factors of PNR in patients with CD treated with the anti-TNF-α monoclonal antibody, and to establish the nomograms prediction model. The area under the curve (AUC) of the receiver operating characteristic curve (ROC), the net reclassification index (NRI), integrated discrimination improvement index (IDI), and decision curve analysis (DCA) were used to evaluate the predictive efficacy and clinical application value of the prediction model. DeLong test was used for statistical analysis.Results:The results of multivariate logistic regression analysis showed that high level of CRP ( OR=1.030, 95% confidence interval (95% CI) 1.002 to 1.059), simplified CDAI ( OR=1.399, 95% CI 1.023 to 1.913), and MM-SES-CD ( OR=1.100, 95% CI 1.025 to 1.181) in baseline were independent risk factors of PNR in patients with CD treated with the anti-TNF-α monoclonal antibody ( P=0.033, 0.036 and 0.008). The results of ROC analysis showed that the AUCs of CRP, simplified CDAI, MM-SES-CD, and the prediction model in the modeling group and the validation group were 0.697(95% CI 0.573 to 0.821), 0.772(95% CI 0.666 to 0.879), 0.819(95% CI 0.725 to 0.912), 0.869 (95% CI 0.786 to 0.951) and 0.856 (95% CI 0.756 to 0.955), respectively. The AUC of the prediction model in the modeling group was greater than those of CRP and simplified CDAI, and the differences were statistically significant ( Z=3.00 and 2.75, P=0.003 and 0.006), while compared with MM-SES-CD and the validation group, the differences were not statistically significant (both P>0.05). However, compared with MM-SES-CD, the NRI and IDI of the prediction model in the modeling group were 0.205(95% CI 0.002 to 0.409, P=0.048) and 0.098(95% CI 0.022 to 0.174, P=0.011), respectively, suggesting that the predictive ability of the prediction model was better than that of MM-SES-CD. The results of DCA indicated that the prediction model had significant clinical benefits in both the modeling group and the validation group. Conclusions:A prediction model was successfully constructed based on the independent risk factors for PNR in patients with CD treated with the anti-TNF-α monoclonal antibody. After verification, the prediction model has good prediction performance and significant clinical benefits.

Effects of biologics on psychological status and quality of life in patients with inflammatory bowel disease: a multicenter study / 中华内科杂志

Objective:To investigate the effects of biologics on psychological status and quality of life in patients with inflammatory bowel disease (IBD).Methods:A cross-sectional survey was conducted in 42 hospitals in 22 provinces (autonomous regions and municipalities directly under the central government) from September 2021 to May 2022. General clinical information and the use of biologics were obtained from adult patients diagnosed with IBD who voluntarily participated in the study. Psychological status was evaluated using the Generalized Anxiety Disorder (GAD-7), Patient Health Questionnaire-9 (PHQ-9), Pittsburgh Sleep Quality Index (PSQI), and Inflammatory Bowel Disease Questionnaire (IBDQ) assessment tools. Counts were analyzed via the Chi-square test, and datasets that were not normally distributed were analyzed via nonparametric tests. P<0.05 was considered statistically significant. Results:A total of 2 478 valid questionnaires were collected. The GAD-7 score of the biologics group was significantly lower than that of the non-use group [6 (2, 9) vs. 7 (3, 10), Z=-3.49, P<0.001]. IBDQ scores [183 (158, 204) vs. 178 (152, 198), Z=-4.11, P<0.001], intestinal symptom scores [61 (52, 67) vs. 58 (49, 65), Z=-5.41, P<0.001], systemic symptom scores [28 (24, 32) vs. 27 (23, 31), Z=-2.37, P=0.018], emotional ability scores [69 (58, 77) vs. 67 (56, 75), Z=-3.58, P<0.001] and social ability scores [26 (22, 29) vs. 25 (22, 29), Z=-2.52, P=0.012] in the biologics group were significantly higher than in the non-use group. GAD-7 scores [5 (2, 9) vs. 6 (3, 10), Z=-3.50, P<0.001] and PSQI scores [6 (4, 9) vs. 6 (4, 9), Z=-2.55, P=0.011] were significantly lower in the group using infliximab than in the group not using it. IBDQ scores were significantly higher in patients using vedolizumab than in those not using it [186 (159, 205) vs. 181 (155, 201), Z=-2.32, P=0.021] and were also significantly higher in the group treated with adalimumab than in the group not treated with adalimumab [187 (159, 209) vs. 181 (155, 201), Z=-2.16, P=0.030]. However, ustekinumab had no significant effect on any of the scores. Conclusion:The use of biologics is strongly associated with improvements in anxiety status and quality of life in IBD patients.

Elevated serum nuclear factor erythroid 2-related factor 2 levels contribute to a poor prognosis after acute supratentorial intracerebral hemorrhage: A prospective cohort study.

Objective: Nuclear factor erythroid 2-related factor 2 (Nrf2) is a key transcriptional factor for antioxidant response element-regulated genes. The purpose of this study was to assess the prognostic role of serum Nrf2 in intracerebral hemorrhage (ICH). Materials and methods: In this prospective observational study, serum Nrf2 levels of 115 acute supratentorial ICH patients and 115 controls were gaged. Early neurologic deterioration (END) was defined as an increase of four or greater points in National Institutes of Health Stroke Scale (NIHSS) score or death at post-stroke 24 h. A poor outcome was referred to as the post-stroke 90-day modified Rankin scale (mRS) score of 3-6. END and a poor outcome were considered as the two prognostic parameters. Results: As compared to controls, serum Nrf2 levels of patients were substantially elevated (P < 0.001), with its levels increasing during the 6-h period immediately, peaking in 12-18 h, plateauing at 18-24 h, and decreasing gradually thereafter (P < 0.05). Serum Nrf2 levels of patients were independently correlated with NIHSS score (t = 3.033; P = 0.003) and hematoma volume (t = 3.210; P = 0.002), independently predicted END (odds ratio 1.125; 95% confidence interval 1.027-1.232; P = 0.011) and poor outcome (odds ratio 1.217; 95% confidence interval 1.067-1.387; P = 0.013), as well as efficiently distinguished END (area under curve 0.771; 95% confidence interval 0.666-0.877; P < 0.001) and poor outcome (area under curve 0.803; 95% confidence interval 0.725-0.882; P < 0.001). Its predictive ability was equivalent to those of NIHSS score and hematoma volume (both P > 0.05), and it also significantly improved their predictive abilities under receiver operating characteristic (ROC) curve (all P < 0.05). Conclusion: Elevated serum Nrf2 levels are closely correlated with severity, END, and 90-day poor outcome following ICH. Hence, Nrf2 may play an important role in acute brain injury after ICH, and serum Nrf2 may have the potential to serve as a prognostic biomarker of ICH.

Research on brownfield redevelopment based on Wuli-Shili-Renli system theory and catastrophe progression method.

Brownfields are an important part of urban land resources. Strengthening the governance and redevelopment of brownfields is significant to environmental protection, high-quality urban development and sustainable development. However, due to the complexity and harmfulness of brownfield pollution, the hasty, untimely, and blind development can cause serious consequences. It is infeasible to pay more attention to development than governance or vice versa. In this paper, aiming at brownfield redevelopment evaluation, we introduced the Wuli-Shili-Renli (WSR) system methodology, an oriental system thought combining qualitative and quantitative analyses, comprehensively analyzed the influencing factors of brownfields from three dimensions of Wuli, Shili and Renli, and constructed the evaluation index system of brownfield redevelopment. To avoid much subjectivity in the evaluation process, we established the evaluation model of brownfield redevelopment using the catastrophe progression method. Taking the renovation project of Shanghai Xintiandi in 1999-2001 as a reference, the evaluation index system and evaluation model were applied to the renovation project of Wenjia Street in Qingyang District, Chengdu, Sichuan Province, China in 2022, and the results provided a good basis for the decision-making process.

Usability of serum annexin A7 as a biochemical marker of poor outcome and early neurological deterioration after acute primary intracerebral hemorrhage: A prospective cohort study.

Objective: Annexin A7 (ANXA7), a calcium-dependent phospholipid-binding protein, may act to aggravate brain injury. This study aimed to assess the clinical utility of serum ANXA7 as a predictor of severity, early neurological deterioration (END), and prognosis after intracerebral hemorrhage (ICH). Methods: A total of 126 ICH patients and 126 healthy controls were enrolled. Symptomatic severity was evaluated utilizing the National Institutes of Health Stroke Scale (NIHSS) score. The lesion volume of ICH was measured according to the ABC/2 method. END was referred to as an increase of 4 or greater points in the NIHSS score or death at post-stroke 24 h. The unfavorable functional outcome was a combination of death and major disability at post-stroke 90 days. Results: Serum ANXA7 levels were significantly higher in patients than in controls (median, 46.5 vs. 9.7 ng/ml; P < 0.001). Serum ANXA7 levels were independently correlated with NIHSS score [beta: 0.821; 95% confidence interval (CI): 0.106-1.514; variance inflation factor: 5.180; t = 2.573; P = 0.014] and hematoma volume (beta: 0.794; 95% CI: 0.418-1.173; variance inflation factor: 5.281; t = 2.781; P = 0.007). Serum ANXA7 levels were significantly elevated with increase in modified Rankin scale scores (P < 0.001). Also, serum ANXA7, which was identified as a categorical variable, independently predicted END and an unfavorable outcome with odds ratio values of 3.958 (95% CI: 1.290-12.143; P = 0.016) and 2.755 (95% CI: 1.051-7.220; P = 0.039), respectively. Moreover, serum ANXA7 levels efficiently differentiated END (area under the curve: 0.781; 95% CI: 0.698-0.849) and an unfavorable outcome (area under the curve: 0.776; 95% CI: 0.693-0.846). Conclusion: Serum ANXA7 may represent a useful blood-derived biomarker for assessing the severity, END, and prognosis of ICH.

Predictive value of serum visinin-like protein-1 for early neurologic deterioration and three-month clinical outcome in acute primary basal ganglia hemorrhage: A prospective and observational study.

BACKGROUND: Visinin-like protein 1 (VILIP-1) appears as a biomarker of neuronal injury. We investigated the correlation of serum VILIP-1 concentrations with severity, early neurologic deterioration (END) and functional outcome of intracerebral hemorrhage (ICH). METHODS: In this prospective and observational study, serum VILIP-1 concentrations were quantified in 106 patients with basal ganglia hemorrhage. Univariate and multivariable logistic regression analyses were used to analyze the relationship between serum VILIP-1 concentrations and END plus worse prognosis (modified Rankin Scale score of 3 or greater) at post-injury 3 months. RESULTS: Serum VILIP-1 concentrations of patients were closely correlated with hematoma volume and National Institutes of Health Stroke Scale score. Serum VILIP-1 concentrations were substantially elevated in patients with END or worse 3-month prognosis, as compared to other remainders. Also, serum VILIP-1 concentrations were independently associated with END and worse 3-month prognosis. Under ROC curve analysis, serum VILIP-1 concentrations exhibited marked accuracy for distinguishing patients with the development of END or worse 3-month prognosis. Its predictive ability was in the range of hematoma volume and National Institutes of Health Stroke Scale score. CONCLUSIONS: Serum VILIP-1 may be a good biomarker for assessing hemorrhagic severity and clinical outcomes after ICH.

Clinical study on Xiefei Tongfu Decoction combined with conventional western medicine therapy for the patients with pulmonary pseudomonas aeruginosa infection after brain trauma and syndrome of phlegm-heat and bowel-repletion / 国际中医中药杂志

Objective:To analyze the effects of Xiefei Tongfu Decoction on syndrome of phlegm-heat and bowel-repletion in patients with pulmonary pseudomonas aeruginosa infection after brain trauma.Methods:A total of 90 patients with pulmonary pseudomonas aeruginosa infection after traumatic brain injury received treatment in our hospital from August 2018 to May 2021 were selected and randomly divided into control group ( n=45) and study group ( n=45) by the random digital table method. The control group was treated with conventional western medicine, and the study group was treated with Xiefei Tongfu decoction and conventional western medicine. The TCM syndrome scores, inflammatory factor levels, like C-reactive protein (CRP), interleukin-6 (IL-6), white blood cell count (WBC), and lung function indexes, like forced vital capacity (FVC), forced expiratory volume rate in the first second (FEV1), expiratory volume percentage in forced vital capacity (FEV1/FVC) were compared between the two groups before and after treatment. The clinical effect and adverse events of the two groups were compared. Results:The total effective rate was 91.11% (41/45) in the study group and 73.33% (33/45) in the control group, with a statistically significant difference between the two groups ( χ2=4.97, P=0.027). After treatment, the scores of dizziness, headache, forgetfulness, insomnia and total scores in the study group were significantly lower than those in the control group ( t values were 9.65, 9.81, 8.62, 9.11, 9.34, all Ps<0.01). After treatment, CRP [(95.66±11.67) mg/L vs. (107.82±12.99) mg/L, t=4.67], IL-6 [(25.16±6.46) ng/L vs. (33.45±7.33) ng/L, t=5.69], WBC [(9.35±2.02)×10 9/L vs. (13.12±2.18)×10 9/L, t=8.51] in the control group were significantly lower than those in the control group ( P<0.01). After treatment, the FEV1 [(2.34±0.31) L vs. (1.92±0.33) L, t=6.22], FVC [(3.45±0.46) L vs. (2.96±0.37) L, t=5.57], FEV1/FVC [(68.82±8.64)% vs. (64.86±9.56)%, t=2.18] in the control group significantly higher than those in the control group ( P<0.01 or P<0.05), and no serious adverse events occurred in any groups, and there was no significant difference between the two groups ( χ2=1.39, P=0.238). Conclusion:The Xiefei Tongfu Decoction has a significant effect on patients with pulmonary pseudomonas aeruginosa infection after brain trauma, which can improve symptoms, relieve inflammatory response and enhance lung function with safety.

Needs and requirements for general practice department in general hospitals from the perspective of grassroots: a qualitative study / 中华全科医师杂志

Objective:To survey the needs and requirements of the general practice department in general hospitals from the perspective of grassroots health care personnel.Methods:From July 2020 to February 2022, a qualitative study on needs and requirements for the general practice department in general hospitals was conducted. Twenty eight participants from community health service centers in Beijing, Xi′an and Guangzhou were selected for the in-depth interviews.Results:The participants expressed their opinions and suggestions on the community needs and requirements for general practice department in general hospitals as follows. (1) The necessity of establishing department of general practice in general hospitals: the general hospitals had advantages to meet the medical needs of the community; the teaching and training should be focus on the way of thinking in the general practice, while the training needs for research ability was less required. (2) The cooperation between general hospital and its community teaching base: to implement the joint teaching rounds and joint home visits were effective ways for collaboration, which may ensure the quality of clinical faculty in the community bases. (3)The training needs of the community: rational use of drugs was most required, sub-specialty training was another concern for general practitioners in grassroots level. (4) The requirements for general practice department in the general hospital: in addition to complete organizational structure, daily teaching work needs to be implemented, and horizontal and vertical connection to relevant health institutions also need to be strengthened. Meanwhile, the teaching work should be a considerable part in the department performance assessment, and excellent clinical ability was also required to facilitate the effective referral of patients from the community.Conclusions:The study shows the necessity of establishing department of general practice in general hospitals, and various needs from the community teaching base, which providing reference for improving the construction of general practice department in the future.

Salidroside inhibits phenotypic transformation of rat pulmonary artery smooth muscle cells induced by hypoxia / 中国中药杂志

This study investigated the effect of salidroside on phenotypic transformation of rat pulmonary artery smooth muscle cells(PASMCs) induced by hypoxia. Rat pulmonary arteries were isolated by tissue digestion and PASMCs were cultured. The OD values of cells treated with salidroside at different concentrations for 48 hours were measured by cell counting kit-8(CCK-8) to determine the appropriate concentration range of salidroside. The cells were divided into a normal(normoxia) group, a model(hypoxia) group, and three hypoxia + salidroside groups(40, 60, and 80 μg·mL~(-1)). Quantitative real-time PCR(qRT-PCR) was used to detect the mRNA expression of cell contractile markers in each group, such as α-smooth muscle actin(α-SMA), smooth muscle 22(SM22), and calcium-binding protein(calponin), and synthetic marker vimentin. The expression levels of cell phenotypic markers and proliferating cell nuclear antigen(PCNA) were detected by Western blot. The proliferation of cells in each group was detected by the 5-ethynyl-2'-deoxyuridine(EdU) assay. Cell migration was measured by Transwell assay. As revealed by results, compared with the normal group, the model group showed decreased mRNA and protein expression of contractile phenotypic markers of PASMCs and increased mRNA and protein expression of synthetic markers. Compared with the conditions in the model group, salidroside could down-regulate the mRNA and protein expression of synthetic markers in PASMCs and up-regulated the mRNA and protein expression of contractile phenotypic markers. Compared with the normal group, the model group showed potentiated proliferation and migration. Compared with the model group, the hypoxia + salidroside groups showed blunted proliferation and migration of cells after phenotypic transformation. The results suggest that salidroside can inhibit the expression of synthetic markers in PASMCs and promote the expression of contractile markers to inhibit the hypoxia-induced phenotypic transformation of PASMCs. The mechanism of salidroside in inhibiting the proliferation and migration of PASMCs is related to the inhibition of the phenotypic transformation of PASMCs.

A multicenter survey on the psychological status and quality of life of patients with inflammatory bowel disease in China / 中华消化杂志

Objective:To investigate the psychology status and quality of life in patients with inflammatory bowel disease(IBD) in China, and to analyze the influencing factors.Methods:From September 2021 to May 2022, 42 hospitals in 22 provinces(autonomous regions and municipalities directly under the central government) in China, the clinical data of 2 478 IBD patients were collected, which included age, gender, weight, first visit or not, disease activity, disease course, main clinical manifestations(diarrhea, abdominal pain, hematochezia, extraintestinal manifestations), complications, treatment medication(5-aminosalicylic acid, glucocorticoids, immunosuppressive agents, and biological agents), and whether to have surgery. Anxiety, depression, sleep quality and quality of life of IBD patients were evaluated by generalized anxiety disorder-7 items, patient health questionnaire-9 items, Pittsburgh sleep quality index and inflammatory bowel disease questionnaire, and the related influencing factors were analyzed. Univariate analysis and multiple linear regression analysis were used for statistical analysis.Results:The average age of 2 478 IBD patients was 37.96 years old, and male counted for 62.43%(1 547/2 478). There were 61.82%(1 532/2 478) of the IBD patients in the active stage of disease, mostly mild or moderate(588 and 734 cases). There were 60.61%(1 502/2 478) of the IBD patients with different degrees of anxiety, 58.35%(1 446/2 478) of the IBD patients with different degrees of depression, and 48.87%(1 211/2 478) of the IBD patients had different degrees of sleep problems. The results of multiple linear regression analysis indicated that female, higher level of disease activity and longer disease course were independent risk factors of anxiety, depression and sleep quality in the IBD patients(unstandardized regression coefficient(95% confidence interval) 1.08(0.65 to 1.50), 0.45(0.23 to 0.68), 0.19(0.02 to 0.36), 0.83(0.33 to 1.32), 0.62(0.36 to 0.88), 0.28(0.08 to 0.47), 0.47(0.16 to 0.77), 0.39(0.23 to 0.55), 0.14(0.02 to 0.26); P<0.001, <0.001, =0.025 , =0.001, <0.001, =0.005, =0.003, <0.001, =0.027). The usage of biological agents was an independent protective factor of anxiety(unstandardized regression coefficient(95% confidence interval) -0.67(-1.17 to -0.17), P=0.008), and older age was an independent risk factor of sleep quality(unstandardized regression coefficient(95% confidence interval) 0.35(0.09 to 0.61), P=0.008). Higher level of disease activity, symptoms of diarrhea, abdominal pain, presence of extraintestinal manifestations, usage of 5-aminosalicylic acid and glucocorticoid, and with surgical treatment were independent risk factors of quality of life(unstandardized regression coefficient(95% confidence interval) -11.00(-12.24 to -9.76), -2.90(-5.26 to -0.55), -3.93(-6.25 to -1.61), -5.79(-9.87 to -1.71), -4.78(-7.79 to -1.76), -7.71(-11.07 to -4.35), -4.37(-8.00 to -0.73); P<0.001, =0.016, =0.001, =0.005 , =0.002, <0.001, =0.019), while the usage of biological agents was an independent protective factor of quality of life (unstandardized regression coefficient(95% confidence interval) 4.72(1.97 to 7.48), P=0.001). Conclusion:IBD patients generally have different degrees of anxiety, depression and sleep problems, which affect the quality of life of patients. Gender, disease activity and disease course are the influencing factors of mental disorders in IBD patients.
