objectiveTo investigate the differences in clinical indices and lipid metabolism between the patients with nonalcoholic fatty liver disease （NAFLD） and healthy individuals in the overweight population. MethodsIn this study， body mass index （BMI）>23 kg/m2 was defined as overweight. A total of 62 overweight patients with NAFLD who were admitted to Putuo Hospital Affiliated to Shanghai University of Traditional Chinese Medicine from August 2020 to April 2021 were enrolled as overweight NAFLD group， and 50 overweight individuals who underwent physical examination during the same period of time were enrolled as control group. Clinical information and blood biochemical parameters were recorded for all subjects. Ultra-performance liquid chromatography-tandem mass spectrometry was used to analyze serum lipidomic profile， and principal component analysis and orthogonal partial least squares-discriminant analysis were used to perform the multivariate statistical analysis of lipidomic data. The chi-square test was used for comparison of categorical data between two groups， and the independent-samples t test or the Wilcoxon rank-sum test was used for comparison of continuous data between two groups. ResultsThe overweight NAFLD group had a significantly higher BMI than the overweight control group （Z=-2.365， P=0.018）. As for serological markers， compared with the overweight control group， the overweight NAFLD group had significantly higher levels of red blood cells， hemoglobin， hematocrit， uric acid， total protein， globulin， alkaline phosphatase， gamma-glutamyl transpeptidase， alanine aminotransferase， aspartate aminotransferase， cholinesterase， low-density lipoprotein， total cholesterol， triglyceride， apolipoprotein B， and blood glucose （all P<0.05）. The lipidomic analysis showed that there was a significant difference in lipid metabolism between the two groups， and a total of 493 differentially expressed lipids were identified （VIP value>1， P<0.05）， among which 143 lipids were significantly upregulated and 350 lipids were significantly downregulated in the overweight NAFLD group. The mean total fatty acid content in the overweight NAFLD group was 3.6 times that in the overweight control group. Compared with the overweight control group， the overweight NAFLD group had a significant reduction in the content of triglyceride with>3 unsaturated bonds （P<0.001） and a significant increase in the content of triglyceride with ≤3 unsaturated bonds （P<0.001）. ConclusionCompared with healthy overweight individuals， overweight NAFLD patients tend to have significant abnormalities in some biochemical parameters and lipid metabolites， with significant increases in the content of fatty acid in blood and the types of saturated fat chains in triglycerides.

Correlation between serum N-terminal pro-B-type natriuretic peptide level and echocardiographic parameters in patients with chronic Keshan disease / 中华地方病学杂志

Objective:To study the correlation between serum N-terminal pro-B-type natriuretic peptide (NT-proBNP) level and echocardiographic parameters in patients with chronic Keshan disease, providing reference for diagnosis and prognosis evaluation of chronic Keshan disease.Methods:Ninety-nine patients with chronic Keshan disease who received standardized treatment at Jingchuan County People's Hospital in Pingliang City, Gansu Province from January to December 2020 were selected. Among them, 16 patients were classified as cardiac function grade Ⅱ according to New York Heart Association (NYHA), 69 as grade Ⅲ and 14 as grade Ⅳ. The patients underwent echocardiography and their serum NT-proBNP level was measured using fluorescence immunochromatography. The differences in serum NT-proBNP levels among patients with different cardiac function grades were compared, and the correlation between cardiac function grades, serum NT-proBNP level and echocardiographic parameters was analyzed.Results:The serum NT-proBNP levels in patients with cardiac function grades Ⅱ, Ⅲ, and Ⅳ were (1 107.26 ± 268.03), (2 125.98 ± 293.02), and (8 268.59 ± 2 659.50) pg/ml, respectively. The differences among the three groups were statistically significant ( F = 13.94, P < 0.001). The serum NT-proBNP level was positively correlated with cardiac function grades ( r = 0.44, P < 0.001), left ventricular end-diastolic diameter, left ventricular end-systolic diameter, and left atrial diameter ( r = 0.45, 0.52, 0.38, P < 0.001), and negatively correlated with fractional shortening and left ventricular ejection fraction ( r = - 0.39, - 0.46, P < 0.001). Conclusions:The serum NT-proBNP level in patients with chronic Keshan disease with different cardiac function grades is different, and is positively correlated with echocardiographic parameters reflecting the degree of cardiac structural and functional impairment. The NT-proBNP level may become an early diagnostic, grading, and prognostic indicator for chronic Keshan disease.

Nomogram model based on multiparametric MRI combined with clinical features in identifying benign and malignant BI-RADS 4 lesions / 中华放射学杂志

Objective:To investigate the efficacy of the nomogram model based on multiparametric MRI combined with clinical features for differential diagnosis of benign and malignant breast imaging reporting and data system (BI-RADS) 4 lesions.Methods:This study was a cross-sectional study. Clinical and imaging data of 56 patients (66 lesions) with pathologically confirmed BI-RADS 4 breast lesions from January 2020 to June 2022 at Second Affiliated Hospital of Shantou University Medical College were retrospectively analyzed. The patients were all females aged 42 (17, 71) years old. All patients underwent the breast MRI, including T 1WI, T 2WI, diffusion-weighted imaging, diffusion kurtosis imaging (DKI), and dynamic-enhanced MRI (DCE-MRI), and the patient clinical characteristics, imaging characteristics as well as relevant MRI quantitative parameters were recorded. Comparisons of the indicators of benign and malignant BI-RADS 4 lesions were performed by sample t-test , Mann-Whitney U, or χ 2 test. The least absolute shrinkage and selection operator regression was utilized to further select indicators with statistically significant differences in univariate analyses, and finally, nomogram models were constructed and reclassified all the lesions. Results:Of the 66 lesions in 56 patients, 24 lesions were found in 24 malignant patients and 42 lesions in 32 benign patients. The differences in age, body mass index, and menopausal status between benign and malignant patients were statistically significant (all P<0.05); the differences in tumor longest diameter, type of lesion enhancement, time-single intensity curve type, mean diffusivity and mean kurtosis (MK) between benign and malignant lesions were statistically significant (all P<0.05). After feature selection, MK ( OR=27.952, 95% CI 1.301-600.348, P=0.033), age ( OR=1.140, 95%CI 1.040-1.249, P=0.005), and the type of lesion enhancement ( OR=0.045, 95%CI 0.006-0.316, P=0.005) were the independent influences in predicting BI-RADS 4 malignant lesions. Using this to construct a nomogram model, its area under the curve for predicting BI-RADS 4 malignant lesions was 0.946, and the accuracy of reclassifying 66 BI-RADS 4 lesions as benign versus malignant was 86.36% (57/66). Conclusion:The nomogram model constructed with MK from DKI parameters, the type of lesion enhancement from DCE-MRI, and age is valuable in diagnosing the benign and malignant nature of BI-RADS 4 lesions.

HYDIN mutation status as a potential predictor of immune checkpoint inhibitor efficacy in melanoma.

BACKGROUND: The advent of immune checkpoint inhibitors (ICIs) has altered the outlook for cancer treatment. The estimation of predictive biomarkers could contribute to maximizing the benefits from ICIs treatment. Here, we explored the association between HYDIN mutations (HYDIN-MUT) in melanoma and ICIs efficacy. METHODS: Clinical data and sequencing data from published studies were utilized to assess the association between HYDIN-MUT and the efficacy of ICIs treatment in melanoma patients. RESULTS: Compared to other tumor types, HYDIN (36.14%) has the highest mutation rate in melanoma patients. In the anti-PD-1 treated cohort (n = 254), the HYDIN-MUT patients had a longer OS after ICIs treatment than the HYDIN wild-type (HYDIN-WT) patients (HR = 0.590 [95% CI, 0.410-0.847], P = 0.004); the objective response rate (ORR) and durable clinical benefit (DCB) were increased in patients with HYDIN-MUT (ORR = 46.25, DCB = 56.00%) compared to patients with HYDIN-WT (ORR = 30.99%, DCB = 42.76%) (ORR: P = 0.019; DCB: P = 0.060). In the anti-CTLA4 treated cohort (n = 174), HYDIN-MUT patients achieved significantly longer OS than HYDIN-WT patients (HR = 0.549 [95% CI, 0.366-0.823], P = 0.003); the proportion of ORR and DCB in HYDIN-MUT patients was significantly higher than that in HYDIN-WT patients (ORR 40.54% vs. 14.42%, P = 0.031; DCB 45.76% vs. 22.22%, P = 0.002). Further gene set enrichment analysis demonstrated that DNA repair and anti-tumor immunity were significantly enhanced in HYDIN-MUT patients. CONCLUSIONS: HYDIN mutations are a potential predictive biomarker of ICIs efficacy in melanoma patients.

Construction and application of enhanced recovery after surgery-optimized management system with nurse-led multidisciplinary cooperation.

AIM: To evaluate the effect of enhanced recovery after surgery (ERAS)-optimized management system with nurse-led multidisciplinary cooperation. DESIGN: A quasi-experimental design. METHODS: Nursing department cooperated with medical and clinical department to establish an ERAS-optimized management system. After the system was developed, it was applied in surgical departments of the hospital. Using convenience sampling, 220 selective surgical patients, 82 nurses and 98 doctors from January 1st, 2021 to July 31st, 2021 were selected as the trial group. 220 selective surgical patients, 82 nurses and 98 doctors were selected as the control group from January 1st, 2020 to July 31st, 2020. ERAS observation indicators were compared between the two groups before and 6 months after implementation. The nurse professional identity scores and satisfaction of medical cooperation scores of the two groups at different time points were analysed by repeated analysis of variance. RESULTS: After the implementation, ERAS observation indicators in the trial group were better than the control group (p < 0.05). There were significant differences in the group main effect, time main effect and interaction effect of nurse professional identity scores, satisfaction of medical cooperation scores and scores in all dimensions between the two groups (p < 0.05). The scores of the experimental group at 3 months and 6 months after implementation were better than those of the control group (p < 0.05). CONCLUSIONS: Enhanced recovery after surgery-optimized management system with nurse-led multidisciplinary cooperation was an effective working method. It could promote patients recovery and enhance nurse professional identity.

Single-shot AAV-vectored vaccine against SARS-CoV-2 with fast and long-lasting immunity

Due to the insufficient long-term protection and significant efficacy reduction to new variants of current COVID-19 vaccines, the epidemic prevention and control are still challenging. Here, we employ a capsid and antigen structure engineering (CASE) strategy to manufacture an adeno-associated viral serotype 6-based vaccine (S663V-RBD), which expresses trimeric receptor binding domain (RBD) of spike protein fused with a biological adjuvant RS09. Impressively, the engineered S663V-RBD could rapidly induce a satisfactory RBD-specific IgG titer within 2 weeks and maintain the titer for more than 4 months. Compared to the licensed BBIBP-CorV (Sinopharm, China), a single-dose S663V-RBD induced more endurable and robust immune responses in mice and elicited superior neutralizing antibodies against three typical SARS-CoV-2 pseudoviruses including wild type, C.37 (Lambda) and B.1.617.2 (Delta). More interestingly, the intramuscular injection of S663V-RBD could overcome pre-existing immunity against the capsid. Given its effectiveness, the CASE-based S663V-RBD may provide a new solution for the current and next pandemic.

Bioconversion of C1 gases and genetic engineering modification of gas-utilizing microorganisms / 生物工程学报

C1 gases including CO, CO2 and CH4, are mainly derived from terrestrial biological activities, industrial waste gas and gasification syngas. Particularly, CO2 and CH4 are two of the most important greenhouse gases contributing to climate change. Bioconversion of C1 gases is not only a promising solution to addressing the problem of waste gases emission, but also a novel route to produce fuels or chemicals. In the past few years, C1-gas-utilizing microorganisms have drawn much attention and a variety of gene-editing technologies have been applied to improve their product yields or to expand product portfolios. This article reviewed the biological characteristics, aerobic or anaerobic metabolic pathways as well as the metabolic products of methanotrophs, autotrophic acetogens, and carboxydotrophic bacteria. In addition, gene-editing technologies (e.g. gene interruption technology using homologous recombination, group Ⅱ intron ClosTron technology, CRISPR/Cas gene editing and phage recombinase-mediated efficient integration of large DNA fragments) and their application in these C1-gas-utilizing microorganisms were also summarized.

Photobiomodulation therapy assisted orthodontic tooth movement: potential implications, challenges, and new perspectives / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

Over the past decade, dramatic progress has been made in dental research areas involving laser therapy. The photobiomodulatory effect of laser light regulates the behavior of periodontal tissues and promotes damaged tissues to heal faster. Additionally, photobiomodulation therapy (PBMT), a non-invasive treatment, when applied in orthodontics, contributes to alleviating pain and reducing inflammation induced by orthodontic forces, along with improving tissue healing processes. Moreover, PBMT is attracting more attention as a possible approach to prevent the incidence of orthodontically induced inflammatory root resorption (OIIRR) during orthodontic treatment (OT) due to its capacity to modulate inflammatory, apoptotic, and anti-antioxidant responses. However, a systematic review revealed that PBMT has only a moderate grade of evidence-based effectiveness during orthodontic tooth movement (OTM) in relation to OIIRR, casting doubt on its beneficial effects. In PBMT-assisted orthodontics, delivering sufficient energy to the tooth root to achieve optimal stimulation is challenging due to the exponential attenuation of light penetration in periodontal tissues. The penetration of light to the root surface is another crucial unknown factor. Both the penetration depth and distribution of light in periodontal tissues are unknown. Thus, advanced approaches specific to orthodontic application of PBMT need to be established to overcome these limitations. This review explores possibilities for improving the application and effectiveness of PBMT during OTM. The aim was to investigate the current evidence related to the underlying mechanisms of action of PBMT on various periodontal tissues and cells, with a special focus on immunomodulatory effects during OTM.

Xuebijing alleviates LPS-induced acute lung injury by downregulating pro-inflammatory cytokine production and inhibiting gasdermin-E-mediated pyroptosis of alveolar epithelial cells / 中国天然药物

Acute lung injury/acute respiratory distress syndrome (ALI/ARDS) is characterized by diffuse alveolar injury primarily caused by an excessive inflammatory response. Regrettably, the lack of effective pharmacotherapy currently available contributes to the high mortality rate in patients with this condition. Xuebijing (XBJ), a traditional Chinese medicine recognized for its potent anti-inflammatory properties, exhibits promise as a potential therapeutic agent for ALI/ARDS. This study aimed to explore the preventive effects of XBJ on ALI and its underlying mechanism. To this end, we established an LPS-induced ALI model and treated ALI mice with XBJ. Our results demonstrated that pre-treatment with XBJ significantly alleviated lung inflammation and increased the survival rate of ALI mice by 37.5%. Moreover, XBJ substantially suppressed the production of TNF-α, IL-6, and IL-1β in the lung tissue. Subsequently, we performed a network pharmacology analysis and identified identified 109 potential target genes of XBJ that were mainly involved in multiple signaling pathways related to programmed cell death and anti-inflammatory responses. Furthermore, we found that XBJ exerted its inhibitory effect on gasdermin-E-mediated pyroptosis of lung cells by suppressing TNF-α production. Therefore, this study not only establishes the preventive efficacy of XBJ in ALI but also reveals its role in protecting alveolar epithelial cells against gasdermin-E-mediated pyroptosis by reducing TNF-α release.

A case of erythrogenic protoporphyria with thyrotoxicosis and liver dysfunction in an adult female / 中南大学学报(医学版)

Erythropoietic protoporphyria(EPP)is an inherited metabolic disease caused by the deficiency in ferrochelatase(FECH)encoded by the FECH gene,and it is inherited in an autosomal recessive manner.EPP usually produces acute pain photosensitivity after exposure to sunlight in infancy or early childhood,and liver failure is the most serious associated complication.This article reported an adult female case of EPP complicated with thyrotoxicosis and liver dysfunction which is a rare condition.The patient's liver function improved after liver protection treatment,her thyroid function returned to normal,and her EPP symptoms improved significantly.Moreover,the c.286C＞T gene mutation may be the pathogenic locus of EPP.For patients with abnormal liver function,the possibility of EPP should be considered after the common causes are excluded,and FECH gene detection should be done to confirm the diagnosis in time.When EPP is associated with thyrotoxicosis and liver dysfunction,priority may be given to hepatoprotective therapy.

Comparative study of four technology platforms for detection of thyroid carcinoma NTRK fusion gene / 临床与实验病理学杂志

Purpose To study the consistency of NTRK fu-sion gene in the thyroid carcinoma detected by four technology platforms:immunohistochemistry,DNA-based NGS,FISH and qRT-PCR.Methods NTRK fusion gene was detected by FISH,immunohistochemical(IHC),DNA-based NGS and qRT-PCR in a same group of 40 clinical cases(among them,31 cases were thyroid cancer samples).Results In a group of 31 thyroid cancer cases detected by four techniques,compared with FISH,the sensitivity,specificity,positive predictive value(PPV),negative predictive value(NPV)and total coincidence rate(TCR)of IHC was 100%(9/9),90.9%(20/22),81.8%(9/11),100%(20/20),93.5%(29/31),respectively.The PPV of IHC was poor.The sensitivity,specificity,PPV,NPV and TCR of DNA-based NGS was 44.4%(4/9),100%(22/22),100%(4/4),81.5%(22/27),83.9%(26/31),respectively,and the sensitivity was poor.The TCR of qRT-PCR was 100%(31/31).Compared with FISH,Kappa value of IHC,DNA-based NGS and qRT-PCR was 0.853,0.532 and 1.000,respectively.Of the 40 clinical cases,the concordance between qRT-PCR and FISH was observed for 39 samples,for the qRT-PCR assay did not cover the NTRK fusion type(LM-NA:exon4-NTRK1:exon10).Compared with FISH,the coinci-dence rate of qRT-PCR was highest.Conclusion The RNA-based assay of qRT-PCR does have the advantages of high sensi-tivity and high specificity,and may be an optimal scheme for routine clinical detection of NTRK fusion variation in thyroid cancer in pathology department.

Effect of Compound Duzhong Jiangu Granules on joint function, quality of life and inflammatory factors in patients with Kashin-Beck disease / 中华地方病学杂志

Objective:To study the effect of Compound Duzhong Jiangu Granules on joint function, quality of life and inflammatory factors in patients with Kashin-Beck disease.Methods:By group design, 135 patients with Kashin-Beck disease in Chongxin County, Pingliang City, Gansu Province, were selected and divided into intervention group (100 cases treated with Compound Duzhong Jiangu Granules, 12 g/bag, 1 bag/time, 3 times/day, treatment for 1 month) and control group (35 cases treated with ibuprofen, 0.3 g/capsule, 1 capsule/time, 2 times/day, treatment for 2 weeks) according to the randomized, single-blind principle. The changes of joint dysfunction index score, joint function improvement rate, total scores of Kashin-Beck disease quality of life (KBDQOL) and scores of each dimension were analyzed before treatment, 1 month and 3 months after treatment. The serum levels of interleukin-6 (IL-6), nuclear factor κB (NFκB)-p65, inducible nitric oxide synthase (NOS2), nitric oxide (NO), and prostaglandin E2 (PGE2) were detected by enzyme-linked immunosorbent assay before treatment and 1 month after treatment.Results:The total scores of joint dysfunction index of the intervention group and the control group 1 month after treatment and 3 months after treatment were lower than those before treatment, but 3 months after treatment was higher than 1 month after treatment ( P < 0.001). One month after treatment, the total effective rates of joint function improvement in the intervention group and the control group were 68.00% (68/100) and 54.55% (18/33), respectively; 3 months after treatment, the total effective rates of the intervention group and the control group were 36.00% (36/100) and 39.39%(13/33), respectively. The total scores and scores of each dimension of KBDQOL were not significant for the main effect of the group ( P > 0.05), but significant for the main effect at the time point ( P < 0.05), and there was no interactive effect ( P > 0.05). There were significant differences in the scores of social support and mental status dimensions in the intervention group at different time points ( P < 0.001). And in the intervention group, the total score, the scores of physical function, activity limitation, economy and overall health dimensions were statistically significant between before treatment and 1 month after treatment, 1 month after treatment and 3 months after treatment( P < 0.05); however, there was no significant difference between before treatment and 3 months after treatment ( P > 0.05). One month after treatment, the serum PGE2 levels of both groups were decreased ( P < 0.05), and there was no difference in other inflammatory factors at different groups and time points ( P > 0.05). Conclusion:Compound Duzhong Jiangu Granules can effectively inhibit the inflammatory reaction of patients with Kashin-Beck disease, promote the improvement of joint function and improve the quality of life in various aspects.

Comparison of the application of WOMAC, SF-36 scales and the "Assessment for Therapeutic Efficacy on Kashin-Beck Disease" (WS/T 79-2011) standard in the evaluation of efficacy in patients with Kashin-Beck disease / 中华地方病学杂志

Objective:To compare the application effect among Western Ontario and McMaster University Osteoarthritis Index (WOMAC) scale, Medical Outcomes Study 36-item Short Form (SF-36) scale and "Assessment for Therapeutic Efficacy on Kashin-Beck Disease" (WS/T 79-2011) standard in the evaluation of therapeutic effect of patients with Kashin-Beck disease, which could provide basis for the treatment evaluation of patients with Kashin-Beck disease.Methods:A total of 213 patients with Kashin-Beck disease in Gansu Province were investigated. WOMAC scale, SF-36 scale and standard of WS/T 79-2011 were used to analyze the quality of life of patients before and after treatment. The reliability, construct validity, content validity, discriminant validity of WOMAC and SF-36 scales were compared. Correlation between WOMAC, SF-36 scales and standard of WS/T 79-2011 were evaluated.Results:Both WOMAC and SF-36 scales had good construct validity and content validity (construct validity showed WOMAC and SF-36 scales contained 1 and 2 common factors, respectively; content validity showed WOMAC and SF-36 scales contained 3 and 8 common factors, respectively). The reliability and discriminant validity of WOMAC scale were better than those of SF-36 seale (reliability showed WOMAC reliability coefficient ≥0.934, the reliability coefficient of SF-36 scale was ranged from 0.386 to 0.999. Discriminant validity showed there were differences in 3 dimensions of the WOMAC scale before and after treatment, while there were differences in 6 out of 8 dimensions of the SF-36 scale). The correlation coefficients between WOMAC scale and standard of WS/T 79-2011 ranged from 0.175 to 0.437, the correlation coefficients between SF-36 scale and standard of WS/T 79-2011 ranged from - 0.434 to - 0.099 ( P < 0.05). Conclusion:The reliability, discriminant validity and correlation with the standard of WS/T 79-2011 of WOMAC scale are better than those of SF-36 scale in efficacy evaluation of patients with Kashin-Beck disease.
