Changes in brain susceptibility in Wilson's disease patients: a quantitative susceptibility mapping study.

AIM: To assess changes in the susceptibility of the caudate nucleus (CN), putamen, and globus pallidus (GP) in patients with neurological and hepatic Wilson's disease (WD) by quantitative susceptibility mapping (QSM). MATERIAL AND METHODS: The brain MRI images of 33 patients diagnosed with WD and 20 age-matched controls were analysed retrospectively. All participants underwent brain T1-weighted, T2-weighted, and QSM imaging using a 1.5 T magnetic resonance imaging (MRI) machine. QSM maps were evaluated with the STISuite toolbox. The quantitative susceptibility levels of the CN, putamen, and GP were analysed using region of interest analysis on QSM maps. Differences among neurological WD patients, hepatic patients, and controls were determined. RESULTS: Susceptibility levels were significantly higher for all examined structures (CN, putamen and GP) in patients with neurological WD compared with controls (all p<0.05) and hepatic WD patients (all p<0.05). No statistically significant differences were found in susceptibility levels between patients with hepatic WD and controls (all p>0.05). CONCLUSION: The QSM technique is a valuable tool for detecting changes in brain susceptibility in WD patients, indicating abnormal metal deposition. Notably, the current findings suggest that neurological WD patients exhibit more severe susceptibility changes compared with hepatic WD patients. Therefore, QSM can be utilised as a complementary method to detect brain injury in WD patients.

[Analysis of clinical presentation and genetic characteristics of malignant infantile osteopetrosis].

Objective: To investigate the clinical presentation and genetic characteristics of malignant infantile osteopetrosis. Methods: This was a retrospective case study. Thirty-seven children with malignant infantile osteopetrosis admitted into Beijing Children's Hospital from January 2013 to September 2022 were enrolled in this study. According to the gene mutations, the patients were divided into the CLCN7 group and the TCIRG1 group. Clinical characteristics, laboratory tests, and prognosis were compared between two groups. Wilcoxon test or Fisher exact test were used in inter-group comparison. The survival rate was estimated with the Kaplan-Meier method and the Log-Rank test was used to compare the difference in survival between groups. Results: Among the 37 cases, there were 22 males and 15 females. The age of diagnosis was 0.5 (0.2, 1.0) year. There were 13 patients (35%) and 24 patients (65%) with mutations in CLCN7 and TCIRGI gene respectively. Patients in the CLCN7 group had an older age of diagnosis than those in the TCIRGI group (1.2 (0.4, 3.6) vs. 0.4 (0.2, 0.6) years, Z=-2.60, P=0.008). The levels of serum phosphorus (1.7 (1.3, 1.8) vs. 1.1 (0.8, 1.6) mmol/L, Z=-2.59, P=0.010), creatine kinase isoenzyme (CK-MB) (457 (143, 610) vs. 56 (37, 82) U/L, Z=-3.38, P=0.001) and the level of neutrophils (14.0 (9.9, 18.1) vs. 9.2 (6.7, 11.1) ×109/L, Z=-2.07, P=0.039) at diagnosis were higher in the CLCN7 group than that in the TCIRG1 group. However, the level of D-dimer in the CLCN7 group was lower than that in the TCIRGI group (2.7 (1.0, 3.1) vs. 6.3 (2.5, 9.7) µg/L, Z=2.83, P=0.005). After hematopoietic stem cell transplantation, there was no significant difference in 5-year overall survival rate between the two groups (92.3%±7.4% vs. 83.3%±7.6%, χ²=0.56, P=0.456). Conclusions: TCIRGI gene mutations are more common in children with osteopetrosis. Children with TCIRGI gene mutations have younger age, lower levels of phosphorus, CK-MB, and neutrophils and higher level of D-dimer at the onset. After hematopoietic stem cell transplantation, patients with CLCN7 or TCIRGI gene mutations have similar prognosis.

What are the risks associated with lipiodol hysterosalpingography? A literature review.

INTRODUCTION: Hysterosalpingography is widely used as a first-line investigation for infertility, and may also be therapeutic, increasing pregnancy rates. Aqueous and oil-based contrast agents can be used. Some studies suggest Lipiodol hysterosalpingography has a greater therapeutic effect on fertility than aqueous contrast, though this is contentious. There are additionally safety concerns surrounding Lipiodol hysterosalpingography. This review summarises the adverse effects associated with Lipiodol hysterosalpingography, particularly on thyroid function. KEY FINDINGS: 331 articles were identified. Of these, 46 met inclusion criteria. 3 further articles were identified from reference lists. Complications typically cited in the literature include pain, intravasation, life-threatening oil embolism, and lipogranuloma formation. Emerging evidence suggests that Lipiodol hysterosalpingography may also impact maternal and neonatal thyroid function. Women may develop hypo- or hyperthyroidism. Thyroid dysfunction is clinically significant as even subclinical hypothyroidism reduces fertility, increases the risk of pregnancy complications including miscarriage, pre-eclampsia and perinatal mortality, and adversely impacts foetal neurodevelopment. One study suggested a possible link with neonatal congenital hypothyroidism. CONCLUSION: There is emerging evidence to suggest that Lipiodol hysterosalpingography can cause hypo- or hyperthyroidism, in addition to known adverse effects of pain, intravasation, oil embolism, and lipogranuloma formation. IMPLICATIONS FOR PRACTICE: Given the significance of these risks, and contention surrounding whether Lipiodol truly increases pregnancy rates compared to aqueous mediums, careful consideration is required in the selection of contrast agent. In particular, Lipiodol hysterosalpingography may not be suitable for women with pre-existing thyroid dysfunction.

[Application of TIGIT combined with interleukin-6 detection in the evaluation of Crohn's disease status].

To explore the application of IL-6, PCT, T lymphocyte subsets and TIGIT expression on T lymphocytes in the evaluation of Crohn's disease status. Using a cross-sectional study, total of 119 confirmed patients with Crohn's disease who were treated in the Affiliated Hospital of Jiangxi University of Traditional Chinese Medicine from June 2020 to December 2022 were selected. The age range was 18-59 years old, and the median age (interquartile range) was 37 (29, 45) years old, including 57 cases in active disease group (30 males, 27 females), 62 cases in disease remission group (33 males, 29 females); 50 healthy control groups (27 males, 23 females), the age range was 19-60 years old, and the median age (interquartile range) was 38 (31, 46) years old. The level of IL-6 was detected by flow fluorescence microsphere method, the concentration of PCT was detected by immunochromatography, and the levels of T lymphocyte subsets and TIGIT were detected by flow cytometry. The differences and correlations between the detection indicators in each group were compared, logistic regression was used to analyze the factors influencing the progression of Crosne's disease and the clinical value of each detection indicator was analyzed by ROC curve. The results showed that there were no statistically significant differences in age and gender among the control group, the remission group, and the active group (H=1.422,χ2=0.020;P=0.491, P=0.990); in the active group, IL-6 was 17.55(9.67, 21.72)pg/ml, PCT was 0.38(0.14, 0.43)ng/ml, CD3+CD4+ was 35.47%±6.01%, CD3+CD8+ was 30.50%±5.20%, TIGIT was 25.08%±6.30%; in the remission group, IL-6 was 8.46(5.21, 10.04) pg/ml, PCT was 0.26(0.11, 0.35) ng/ml, CD3+CD4+ was 37.62%±4.86%, CD3+CD8+ was 28.30%±5.28%, TIGIT was 34.22%±5.45%; in the control group, IL-6 was 6.13(3.57, 8.12)pg/ml, PCT was 0.17(0.10, 0.21)ng/m, CD3+CD4+ was 39.74%±3.94%, CD3+CD8+ was 26.59%±4.50%, and TIGIT was 37.64%±6.22%.There were significant differences in IL-6, PCT, CD3+CD4+%, CD3+CD8+%, and TIGIT among the three groups(H=58.688, H=18.003, F=9.600, F=8.124, F=65.059;P<0.001, P<0.001, P<0.001, P<0.001, P<0.001), Among them, IL-6 and TIGIT in the active group were significantly different from those in the remission group (P<0.001, P<0.001), and only TIGIT was significantly different between the remission group and the control group (P=0.007);Spearman correlation analysis showed that the expression of TIGIT on T lymphocytes was negatively correlated with the levels of IL-6; the results of Logistic regression analysis showed that IL-6, PCT and TIGIT were independent factors affecting the progression of Crohn's disease;Comparing the ROC curves of the active group and the remission group, found that TIGIT was significantly different from PCT, CD3+CD4+, CD3+CD8+(Z=4.011, Z=4.091, Z=4.157; P<0.001, P<0.001, P<0.001), no statistical difference with IL-6 (Z=1.193, P=0.233). Selected the combined detection of IL-6 and TIGIT with the best AUC area and Youden index, which shows that the clinical value is improved, the AUC area of IL-6+TIGIT was significantly different from that of IL-6 (Z=2.674, P=0.008). In summary, TIGIT of T lymphocytes and IL-6 detection may be valuable in the diagnosis and treatment of Crohn's disease, and the combined detection of TIGIT and IL-6 may be meaningful for evaluating the status of Crohn's disease.

[HbA1c comparison and diagnostic efficacy analysis of multi center different glycosylated hemoglobin detection systems].

Objective: Compare and analyze the results of the domestic Lanyi AH600 glycated hemoglobin analyzer and other different detection systems to understand the comparability of the detection results of different detectors, and establish the best cut point of Lanyi AH600 determination of haemoglobin A1c (HbA1c) in the diagnosis of diabetes. Methods: Multi center cohort study was adopted. The clinical laboratory departments of 18 medical institutions independently collected test samples from their respective hospitals from March to April 2022, and independently completed comparative analysis of the evaluated instrument (Lanyi AH600) and the reference instrument HbA1c. The reference instruments include four different brands of glycosylated hemoglobin meters, including Arkray, Bio-Rad, DOSOH, and Huizhong. Scatter plot was used to calculate the correlation between the results of different detection systems, and the regression equation was calculated. The consistency analysis between the results of different detection systems was evaluated by Bland Altman method. Consistency judgment principles: (1) When the 95% limits of agreement (95% LoA) of the measurement difference was within 0.4% HbA1c and the measurement score was≥80 points, the comparison consistency was good; (2) When the measurement difference of 95% LoA exceeded 0.4% HbA1c, and the measurement score was≥80 points, the comparison consistency was relatively good; (3) The measurement score was less than 80 points, the comparison consistency was poor. The difference between the results of different detection systems was tested by paired sample T test or Wilcoxon paired sign rank sum test; The best cut-off point of diabetes was analyzed by receiver operating characteristic curve (ROC). Results: The correlation coefficient R2 of results between Lanyi AH600 and the reference instrument in 16 hospitals is≥0.99; The Bland Altman consistency analysis showed that the difference of 95% LoA in Nanjing Maternity and Child Health Care Hospital in Jiangsu Province (reference instrument: Arkray HA8180) was -0.486%-0.325%, and the measurement score was 94.6 points (473/500); The difference of 95% LoA in the Tibetan Traditional Medical Hospital of TAR (reference instrument: Bio-Rad Variant II) was -0.727%-0.612%, and the measurement score was 89.8 points; The difference of 95% LoA in the People's Hospital of Chongqing Liang Jiang New Area (reference instrument: Huizhong MQ-2000PT) was -0.231%-0.461%, and the measurement score was 96.6 points; The difference of 95% LoA in the Taihe Hospital of traditional Chinese Medicine in Anhui Province (reference instrument: Huizhong MQ-2000PT) was -0.469%-0.479%, and the measurement score was 91.9 points. The other 14 hospitals, Lanyi AH600, were compared with 4 reference instrument brands, the difference of 95% LoA was less than 0.4% HbA1c, and the scores were all greater than 95 points. The results of paired sample T test or Wilcoxon paired sign rank sum test showed that there was no statistically significant difference between Lanyi AH600 and the reference instrument Arkray HA8180 (Z=1.665,P=0.096), with no statistical difference. The mean difference between the measured values of the two instruments was 0.004%. The comparison data of Lanyi AH600 and the reference instrument of all other institutions had significant differences (all P<0.001), however, it was necessary to consider whether it was within the clinical acceptable range in combination with the results of the Bland-Altman consistency analysis. The ROC curve of HbA1c detected by Lanyi AH600 in 985 patients with diabetes and 3 423 patients with non-diabetes was analyzed, the area under curve (AUC) was 0.877, the standard error was 0.007, and the 95% confidence interval 95%CI was (0.864, 0.891), which was statistically significant (P<0.001). The maximum value of Youden index was 0.634, and the corresponding HbA1c cut point was 6.235%. The sensitivity and specificity of diabetes diagnosis were 76.2% and 87.2%, respectively. Conclusion: Among the hospitals and instruments currently included in this study, among these four hospitals included Nanjing Maternity and Child Health Care Hospital in Jiangsu Province (reference instrument: Arkray HA8180), Tibetan Traditional Medical Hospital of TAR (reference instrument: Bio-Rad Variant Ⅱ), the People's Hospital of Chongqing Liang Jiang New Area (reference instrument: Huizhong MQ-2000PT), and the Taihe Hospital of traditional Chinese Medicine in Anhui Province (reference instrument: Huizhong MQ-2000PT), the comparison between Lanyi AH600 and the reference instruments showed relatively good consistency, while the other 14 hospitals involved four different brands of reference instruments: Arkray, Bio-Rad, DOSOH, and Huizhong, Lanyi AH600 had good consistency with its comparison. The best cut point of the domestic Lanyi AH600 for detecting HbA1c in the diagnosis of diabetes is 6.235%.

Prevalence and influencing factors of anaemia among pregnant women in rural areas of Northwestern China.

OBJECTIVES: Anaemia during pregnancy is a significant public health problem that adversely impacts both the mother and foetus. However, the factors influencing maternal anaemia in deprived areas of Northwestern China have not yet been thoroughly investigated. This study aimed to describe the prevalence and potential influencing factors of anaemia among expectant mothers in rural areas of Northwestern China. STUDY DESIGN: This was a cross-sectional survey. METHODS: A cross-sectional survey of 586 expectant mothers was conducted to investigate the prevalence of anaemia, prenatal healthcare coverage, dietary diversity and nutrient supplementation intake. The study population was selected from the sample areas using a random sampling method. Data were collected through a questionnaire, and haemoglobin concentrations were measured by a capillary blood test. RESULTS: The results show that 34.8% of the study population were anaemic, with 13% having moderate-to-severe anaemia. The results of the regression analysis showed that diet was not significantly associated with haemoglobin concentrations or the prevalence of anaemia. However, regular prenatal healthcare attendance was found to be an important influencing factor for both haemoglobin concentration (ß = 3.67, P = 0.002) and the prevalence of anaemia (odds ratio = 0.59, P = 0.011). CONCLUSIONS: Pregnant women receiving regular prenatal care were less likely to be anaemic; thus, it is essential to implement strategies to improve attendance at maternal public health services to reduce the prevalence of maternal anaemia.

Effects of betaine on growth performance, intestinal health, and immune response of goslings challenged with lipopolysaccharide.

The objective of this experiment was to investigate the effects of betaine on growth performance, serum parameters, intestinal health, and immune performance of goslings in response to lipopolysaccharide (LPS) challenge. A total of 168 healthy male 15-day-old Jiangnan White Goslings were randomly divided into 4 groups, with 6 replicates per treatment and seven goslings per replicate. A 2 × 2 factorial arrangement included 2 factors, that is, LPS challenge (injection of LPS or physiological saline) and betaine (added 0 or 0.06% betaine in diet). The results indicated that LPS challenge significantly reduced the average daily feed intake (ADFI), average daily gain (ADG), and body weight (BW) at 21 D of the goslings, while dietary betaine supplementation tended to increase the ADFI during the LPS stress period (P = 0.08) and BW at 21 D of the goslings (P = 0.09). The LPS-challenged goslings showed higher pro-inflammatory cytokines (interleukin-1 [IL-1ß], interleukin-6 [IL-6], tumor necrosis factor-α (TNF-α), and Interferon-gamma [IFN-γ]) and lower anti-inflammatory cytokine (Interleukin-10 [IL-10]) (P < 0.05) at 21 D of age. Dietary betaine supplementation alleviated LPS-induced increase in pro-inflammatory cytokines. The LPS challenge significantly decreased duodenal and jejunal villus height (VH) and villus height and crypt depth ratio (VCR), while the addition of betaine significantly increased duodenal VH and VCR (P < 0.05). On the other hand, addition of betaine significantly alleviated decline of enzyme activity on lipase, amylase, trypsin, and chymotrypsin in the intestinal of goslings. The LPS challenge significantly increased the content of serum D-lactic acid (D-LA) and the activity of diamine oxidase (DAO) at 21 D of the goslings. The LPS challenge and betaine addition significantly increased the mRNA expression of Occcludin (OCLN) in jejunal mucosa at 28 D of the goslings (P < 0.05). In conclusion, our research demonstrated that betaine can alleviate the decline of growth performance and immune performance in goslings caused by LPS. The results also indicate betaine possesses anti-inflammation properties and improves intestinal barrier functions. We recommend that 0.06% betaine be added into the diet to improve the intestinal health and immune performance of goslings.

Prediction of active ingredients and mechanism of Siwei Jianbu decoction in the treatment of atherosclerosis by network pharmacology.

OBJECTIVE: Siwei Jianbu Decoction (SJD) has been shown to be effective in treating atherosclerosis (AS). However, its mechanism is still unclear. MATERIALS AND METHODS: The active compounds and targets of SJD were identified from the Traditional Chinese Medicine System Pharmacology (TCMSP) database. The target genes of AS were obtained from the Online Mendelian Inheritance in Man (OMIM), GeneCards, DrugBank, and Therapeutic Target (TTD) databases. Interactions between drug and disease targets were analyzed to obtain common targets. Subsequently, "herb-compound-target" and protein-protein interaction (PPI) networks were constructed and analyzed using the Cytoscape software. Thereafter, Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses were performed by DAVID online database. Then, the results were visualized by R software. Finally, molecular docking was performed using AutoDockTools and PyMOL software. RESULTS: A total of 61 active compounds and 377 target genes were identified for SJD, as well as 726 target genes for AS. Interactive analyses revealed 126 common genes between SJD and AS. Quercetin, ellagic acid, baicalein, and kaempferol were the 4 key compounds in SJD. Moreover, eight key targets, namely TNF, SRC, RELA, AKT1, STAT3, JUN, MAPK1 and FOS were found. Results from enrichment analysis indicated that the MAPK pathway may play an important role. The analysis of molecular docking revealed that the key compounds formed strong bonds with their corresponding key targets. CONCLUSIONS: These findings indicate that SJD could prevent AS by inhibiting the expression of genes associated with MAPK pathway such as MAPK1, RELA, and FOS.

[Clinical characteristics and prognosis analysis of 498 cases with drug-induced liver injury].

Objective: To determine the risk factors, clinical characteristics and treatment prognosis, so as to provide reference for clinicians to diagnose, treat and prevent drug-induced liver injury (DILI). Methods: Data of 712 confirmed DILI cases were collected from the Second Affiliated Hospital of Kunming Medical University between 2013 to 2019. Among them, 498 cases were included in the study. All patients medical history, clinical manifestations and classification, laboratory parameters, disease severity, and mortality rate were collected. Statistical analysis was performed using t-test, Mann-Whitney U test/Pearson χ2 test/Fisher's exact test or Spearman's rank test. Results: Among the suspicious drugs causing DILI, single medication accounted for 89.56%, mainly including traditional Chinese medicine (56.43%), anti-tumor and immunomodulatory agents (8.03%), anti-infective drugs (4.42%), antipyretic and analgesic drugs (4.22%) %), etc., while combination medication accounted for 10.44%. The clinical classification was dominated with hepatocyte injury (63.05%), and there was a statistically significant difference in clinical classification among age groups (P<0.001). Age, alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBIL) and total bile acid (TBA) had statistically significant difference among different suspicious drugs in DILI caused by different drug (P<0.001, 0.003, 0.001, <0.001 and <0.001). Laboratory test results showed that there were statistically significant differences in ALT, AST, ALP, γ-glutamyltransferase (GGT), TBA, international normalized ratio (INR), and eosinophils (P<0.001, <0.001, <0.001, 0.018, 0.003 and 0.019, respectively). Chronic hepatitis was more common in the 54 cases who completed histopathological examination of the liver biopsy. Fibrosis degree was higher in the Western medicine group than Chinese herbal medicine group (P<0.05), and the difference was statistically significant (P<0.05). 96.99% of DILI patients were cured or improved, and 3.01% of patients were uncured. Ordinal logistic regression analysis showed that GGT and INR were independent predictors of poor prognosis. Conclusions: Suspicious drugs for DILI are herbal/dietary supplements, anti-tumor and immunomodulatory, anti-infective, and antipyretic and analgesic. The most common clinical classification is hepatocyte injury. Most patients with DILI have a good prognosis after drug withdrawal and GGT and INR are independent predictors of poor prognosis.

[A prospective randomized controlled study on the effects of compound analgesia in ultra-pulsed fractional carbon dioxide laser treatment of post-burn hypertrophic scars in children].

Objective: To investigate the effects of compound analgesia on ultra-pulsed fractional carbon dioxide laser (UFCL) treatment of post-burn hypertrophic s in children. Methods: A prospective randomized controlled study was conducted. From April 2018 to March 2020, 169 pediatric patients with post-burn hypertrophic s admitted to the First Affiliated Hospital of Air Force Medical University were randomly divided into general anesthesia alone group (39 cases, 19 males and 20 females, aged 35 (21, 48) months), general anesthesia+lidocaine group (41 cases, 23 males and 18 females, aged 42 (22, 68) months), general anesthesia+ibuprofen suppository group (41 cases, 25 males and 16 females, aged 38 (26, 52) months), and three-drug combination group with general anesthesia + lidocaine+ibuprofen suppository (48 cases, 25 males and 23 females, aged 42 (25, 60) months), and the pediatric patients in each group were treated with corresponding analgesic regimens when UFCL was used to treat s, and the pediatric patients were given comprehensive care throughout the treatment process. The pain degree of pediatric patients scar was evaluated by facial expression,legs,activity,cry,and consolability (FLACC) of children's pain behavior scale at 0 (immediately), 1, 2, and 4 h after awakening from the first anesthesia, respectively. At 4 h after awakening from the first anesthesia of postoperative pain assessment, the self-made analgesia satisfaction questionnaire was used to evaluate the satisfaction for the analgesic effect of the pediatric patients or their families, and the satisfaction rate was calculated. Within 2 h after the first operation, the occurrences of adverse reactions of the pediatric patients, such as nausea and vomiting, headache, dizziness, drowsiness, etc, were observed and recorded. Before the first treatment and 1 month after the last treatment, the Vancouver scar scale (VSS) was used to evaluate the pediatric patients scar, and the difference value between the two was calculated. Data were statistically analyzed with least significant difference test, Kruskal-Wallis H test, chi-square test and Fisher's exact probability test. Results: At 0 h after awakening from the first anesthesia, the FLACC scores of pediatric patients in general anesthesia+lidocaine group, general anesthesia+ibuprofen suppository group and three-drug combination group were significantly lower than those in general anesthesia alone group (P<0.01). The FLACC scores of the pediatric patients in anesthesia+ibuprofen suppository group and three-drug combination group were significantly lower than that in general anesthesia+lidocaine group (P<0.01), and the FLACC score of the pediatric patients in three-drug combination group was significantly lower than that in general anesthesia+ibuprofen suppository group (P<0.01). At 1 and 2 h after awakening from the first anesthesia, the FLACC scores of pediatric patients in general anesthesia+ibuprofen suppository group and three-drug combination group were both significantly lower than those in general anesthesia alone group and general anesthesia+lidocaine group (P<0.01), and the FLACC score of the pediatric patients in three-drug combination group was significantly lower than that in general anesthesia+ibuprofen suppository group (P<0.01). At 4 h after awakening from the first anesthesia, the FLACC scores of the pediatric patients in general anesthesia+ibuprofen suppository group and three-drug combination group were significantly lower than those in general anesthesia alone group and general anesthesia+lidocaine group (P<0.01). At 4 h after awakening from the first anesthesia, the satisfactions rate with the analgesic effect in the four groups of pediatric patients or their families were 79.49% (31/39), 85.37% (35/41), 87.80% (36/41), and 97.92% (47/48), respectively. The satisfaction rate of the pediatric patients in three-drug combination group was significantly higher than those in general anesthesia alone group, general anesthesia+lidocaine group, general anesthesia+ibuprofen suppository group. Within 2 h after the first operation, there was no significant difference in the overall comparison of adverse reactions such as nausea and vomiting, headache, dizziness, and drowsiness of pediatric patients among the 4 groups (P>0.05). The VSS scores of pediatric patients before the first treatment, 1 month after the last treatment, and and the difference value between the two in the 4 groups were not significantly different (P>0.05). Conclusions: Three-drug combination for analgesia has a good effect in the treatment of hypertrophic scars after burn in pediatric patients with UFCL. Pediatric patients or their families are highly satisfied with the effect, and the treatment effect and incidence of adverse reactions are similar to other analgesic regimens, so it is recommended to be promoted in clinical practice.

[Treatment and prognosis of primary ocular adnexal extranodal marginal zone mucosa-associated lymphoid tissue lymphoma: a report from a single center].

Objective: This study aimed to see how different initial treatment regimens affected the long-term prognosis of patients with extranodal marginal zone mucosa-associated lymphoid tissue lymphoma confining to the ocular adnexal (OAML) . Methods: Between April 2008 and April 2019, 109 patients with initial mucosa-associated lymphoid tissue confining to ocular adnexal were evaluated and followed-up, and the prognosis of various initial treatment regimens were examined. Results: A total of 36 patients underwent complete surgical resection of the lesions, and 73 patients had residual lesions after surgery, of which 37 patients chose watchful waiting, and 36 patients chose treatment. The treatment regimen included local radiotherapy and systemic treatment (chemotherapy, immunochemotherapy, the combination of radiotherapy and chemotherapy, etc.) , and no serious toxic and side effects were observed in patients receiving systemic treatment. The median follow-up time was 61 (10-142) months. The 5-year and 10-year progression-free survival (PFS) of monocular involvement patients were 78.2% and 76.0% . The 5-year and 10-year PFS rates of patients with binocular involvement were 64.4% and 23.5%. There was significant diference in PFS between patients with monocular and binocular involvement (P=0.010) . Patients who received additional treatment had higher PFS than those patients in the watchful waiting group (P=0.046) . The 5-year PFS was 71.4% and 90.1% among patients in the watchful waiting group and those who received additional treatment, whereas the 10-year PFS was 63.5% and 75.1% , respectively. Patients with OAML were still a risk of disease progression after 5 years. Conclusions: Patients with binocular involvement OAML at the start of the disease had a poor prognosis, but treatment could reduce the risk of recurrence/progression. Systemic therapy is one of the first-line treatment options for patients with OAML, who require long-term monitoring.

Mechanistic Study of Macranthoside B Effects on Apoptotic Cell Death in Human Cervical Adenocarcinoma Cells.

Macranthoside B (MB) is a triterpenoid saponin extracted from Lonicera macranthoides, a traditional Chinese medicine. In the current study, we investigated the anticancer potential of MB in various cancer cells and elucidated its underlying mechanisms. MB exposure inhibited cell proliferation, induced mitochondrial membrane potential (MMP) loss, increased sub-G1 accumulation, and resulted in cleavage of caspase-3 and PARP, which are reflective of apoptosis. In HeLa cells, MB induced down-regulation of SOD2 and GPx1, phosphorylation of Akt and PDK1, and thus promoted ROS-mediated apoptosis. This was further supported by the protection of sub-G1 accumulation, MMP loss, cleavage of caspase-3 and PARP in the presence of N-acetylcysteine (NAC). Additionally, MB induced cell death via down-regulation of ubiquitin-like with PHD and ringfinger domains 1 (UHRF1) and Bcl-xL. Taken together, this study provides a new insight into the apoptosis- inducing potential of MB, and its molecular mechanisms are associated with an increase in oxidative stress and inhibition of the PDK1/Akt pathway.

Dietary supplementation of betaine promotes lipolysis by regulating fatty acid metabolism in geese.

Supplementation of betaine in the diet appears to regulate fatty acid metabolism and decrease fat deposition. This study aims to identify the effects of dietary supplementation of betaine on zootechnical performance, fatty acid synthesis, abdominal fat deposition, and morphology. Three hundred healthy, male, one-day-old Jiangnan White geese of similar body weight were randomly divided into 5 groups, with 6 replicates per treatment and 10 geese per replicate, and given the following amounts of supplementary betaine: 0 (group A), 600 mg/kg (group B), 1,200 mg/kg (group C), 1,800 mg/kg (group D), or 2,400 mg/kg (group E). Feed intake (FI), body weight (BW), abdominal fat and sebum thickness, clinical blood parameters, hepatic enzyme activity, and abdominal fat morphology were monitored during the experiment. All geese had free access to feed and water throughout the study. Our results indicate that supplementation of betaine increased zootechnical performance at 21 and 42 d of age. The percentage of abdominal fat and sebum thickness of geese at 63 d of age decreased linearly with the addition of betaine (P < 0.05). The triglyceride (TG) and total cholesterol (TCHOL) content of serum decreased with the increased level of betaine when measured at 63 d of age (P<0.05). Hormone sensitive lipase (HSL) increased with the level of betaine (P<0.05). However, dietary betaine appeared to decrease the activity of fatty acid synthase (FAS) in the geese at 42 d and 63 d of age (P<0.05). The percentage of total area of lipid droplet decreased with the increased level of betaine supplementation. In conclusion, dietary supplementation of betaine increased lipolysis and decreased fat deposition in the finishing period of geese via reducing feed intake. However, the precise mode-of-action is yet unclear and warrants further research.

Individualized Supplement of Folic Acid Based on the Gene Polymorphisms of MTHER/MTRR Reduced the Incidence of Adverse Pregnancy Outcomes and Newborn Defects.

BACKGROUND: The association between conventional folic acid supplement (FAS) in pregnancy and the occurrence of adverse pregnancy outcomes, newborn defects has been proven. However, recent researches have reported a weakened association. Based on the different maternal metabolism capability of folic acid, it's beneficial for clinicians to provide pregnant women with different doses of FAS, that's individualized FAS. SUBJECTS AND METHODS: A total of 2,677 pregnant women in Dazu, Chongqing, China were recruited in this cohort study. 1,539 women volunteered to receive individualized FAS, in which FAS dose increased with the risk level of maternal genotype? specify MTHFR and MTRR (write in full then abbreviate bracket open and close) while 1,138 women received conventional FAS with unified FAS dose. Additionally, 1,964 pregnant women without FAS were retrospectively analyzed as the control. Finally, the incidence of adverse pregnancy outcomes and newborn defects were recorded. RESULTS: Based on the genotype of MTHFR and MTRR, women were identified as five risk levels of folic acid metabolism. The distributions of genotype and risk levels were not significantly different between FAS-individualized supplement group and FAS-unified supplement group. However, compared with control or FAS-unified supplement group, the incidence of spontaneous abortion, prolonged pregnancy, premature labor, fetal macrosomia and congenital heart disease were significantly decreased in FAS-individualized supplement group. In subgroup analysis, individualized FAS significantly improved pregnancy outcomes for women between 20-40 years old and inhibited the occurrence of newborn defects in both women of the first gestation and women of ≥2 gestations. CONCLUSIONS: The application of individualized FAS based on gene polymorphisms was more effective in preventing adverse outcomes in the mother and child.

The impacts of egg storage time and maternal dietary vitamin E on the growth performance and antioxidant capacity of progeny chicks.

Two trials were designed to investigate the impacts of egg storage time and maternal dietary vitamin E (VE) supplementation on the growth performance and antioxidant capacity of progeny chicks. In total 512 Ross 308 broiler breeder hens (71-wk-old) were assigned to 2 dietary VE treatments (6 and 100 mg/kg) for 14 wk. Progeny chicks used in trials 1 and 2 were originated from eggs laid at week 10 (stored 0 d) and week 8 (stored 14 d), and week 14 (stored 0 d) and week 12 (stored 14 d), respectively. The 4 groups in trial 1 consisted of 2 levels of maternal VE (6 and 100 mg/kg) and 2 egg storage time (0 and 14 d). The 8 groups in trial 2 consisted of 2 levels of maternal VE (6 and 100 mg/kg), 2 egg storage time (0 and 14 d) and progeny sex (male and female). In trial 1, egg storage decreased the body weight, the liver total superoxide dismutase and total antioxidant capacity of 21-day-old offspring (P < 0.05), and the body weight gain and feed intake from 8 to 21 d and 1 to 21 d (P < 0.05); and increased the serum and liver malonaldehyde (MDA) of 7-day-old offspring and the ratio of feed: gain (F/G) from 1 to 7 d (P < 0.05). Maternal VE (100 vs. 6 mg/kg) decreased the F/G from 1 to 7 d and increased the serum total superoxide dismutase of 21-day-old offspring (P < 0.05). In trial 2, egg storage decreased the body weight of 42-day-old offspring, and the body weight gain and feed intake from 22 to 42 d and 1 to 42 d (P < 0.05); and increased the serum and liver MDA of 21- and 42-day-old offspring (P < 0.05). Maternal VE (100 vs. 6 mg/kg) reduced the serum MDA of 7-day-old offspring (P < 0.05). Interactively, maternal VE (100 vs. 6 mg/kg) reduced the serum MDA of offspring originated from stored eggs (P < 0.05), but not for that of offspring originated from unstored eggs in the two trials. It can be concluded that egg storage (14 vs. 0 d) decreased the growth performance and antioxidant capacity of offspring, while maternal dietary VE (100 vs. 6 mg/kg) supplementation could partly alleviate the reduction of antioxidant capacity (except for growth performance) of offspring induced by egg storage for the early phase post-hatch.

Omega-3 fatty acids supplementation on major cardiovascular outcomes: an umbrella review of meta-analyses of observational studies and randomized controlled trials.

OBJECTIVE: Omega-3 fatty acids are commonly used as a lipid-lowering agent or dietary supplement for the purpose of prevention of cardiovascular diseases. However, even large-scale clinical trials have not shown significant results demonstrating clear clinical benefits in cardiovascular diseases. Thus, this umbrella review aims to summarize and evaluate the evidence of clinical effects of omega-3 fatty acids supplementation on cardiovascular outcomes through comprehensive analyses of previous randomized controlled trials (RCTs) or observational cohort studies. MATERIALS AND METHODS: We conducted relevant publication search in PubMed, Embase, and Cochrane Database of Systematic Reviews. We retrieved and analyzed 3,298 articles published until August 28th, 2019. RESULTS: We identified 29 relevant articles and analyzed 83 meta-analyses of RCTs or cohort studies therefrom. As a result, we identified 12 cardiovascular outcomes that are related to omega-3 fatty acids supplementation. Among them, total mortality from major cardiovascular causes (RR 0.92, 95% CI 0.86 to 0.98) had significant inverse associations, and moreover, statistical significances were maintained even in subgroup analysis of large-scale RCTs including more than 1,000 patients (RR 0.94, 95% CI 0.88 to 0.99). CONCLUSIONS: Our umbrella review study shows that omega-3 fatty acids supplementation have a clinical benefit in reducing mortality from cardiovascular causes. However, many studies still have shown conflicting results, and therefore, further studies will be needed to verify the clinical benefit of omega-3 supplementation.

Overexpression of secretory leukocyte peptidase inhibitor (SLPI) does not modulate experimental osteoarthritis but may be a biomarker for the disease.

OBJECTIVE: Osteoarthritic cartilage destruction can be regulated by the balance between proteases and anti-proteases. Here, we sought to identify novel cellular protease inhibitors associated with osteoarthritis (OA) pathogenesis. METHODS: Candidate molecules were screened from microarray data of chondrocytes treated with OA-associated catabolic factors. The functions of candidate molecules in OA pathogenesis were examined in primary-culture mouse articular chondrocytes and mouse models of OA, such as those stimulated by destabilization of the medial meniscus (DMM) or intra-articular (IA) injection of adenovirus expressing the candidate gene. The value of the selected candidate molecule as a biomarker of OA was examined by measuring its circulating levels in human and mouse blood. RESULTS: Bioinformatic analysis identified secretory leukocyte peptidase inhibitor (SLPI) as a highly upregulated cellular protease inhibitor in chondrocytes treated with pathogenic catabolic factors, including interleukin (IL)-1ß, hypoxia-inducible factor (HIF)-2α, and zinc importer ZIP8. The adenovirus-mediated overexpression of SLPI in joint tissues did not cause any OA-like change or modulate DMM- or HIF-2α-induced experimental OA in mice. SLPI also did not markedly modulate the expression of OA-associated catabolic or anabolic factors in chondrocytes. However, SLPI was specifically upregulated in OA cartilage, and the serum SLPI levels were significantly elevated in human OA patients and experimental OA mice, suggesting that SLPI may be a biomarker of OA. CONCLUSION: Although SLPI is upregulated in OA chondrocytes, it does not appear to per se modulate OA development in mice. However, it may be a potential biomarker of OA in humans and animal models.

Sestamibi Single-Positron Emission Computed Tomography/Diagnostic-quality Computed Tomography for the localization of abnormal parathyroid glands in patients with primary hyperparathyroidism: What clinicopathologic factors affect its accuracy?

PURPOSE: Sestamibi Single-Positron Emission Computed Tomography/Diagnostic-quality Computed Tomography (MIBI-SPECT/CT) is a common technology used for primary hyperparathyroidism (PHPT) localization in clinical practice. However, the clinicopathologic factors affecting the accuracy of MIBI-SPECT/CT and the potential limitations remain unclear. METHODS: Retrospectively enrolled PHPT patients (n = 280) were analyzed from August 2017 to December 2019. RESULTS: Of 96 patients with PHPT (mean age, 54 years; 63 females), 17 had discordance between MIBI-SPECT/CT and intraoperative findings. Among the 17 patients with discordance, 58.8% had major discordance, which occurred in most patients with multigland disease (MGD). Compared with concordant patients, discordant patients exhibited increased frequencies of autoimmune thyroid disease (29.4% vs 10.1%, p = 0.035), MDG (41.2% vs 3.8%, p = 0.035), higher PTH (296 pg/mL vs 146 pg/mL; p = 0.012),and lower phosphorus levels (0.77 mmol/L vs 0.90 mmol/L; p = 0.024). MDG (odds ratio [OR], 16.95; 95% CI 2.10-142.86), parathyroid lesion size of 12 mm or less (OR, 6.93; 95% CI 1.41-34.10), and a PTH level higher than 192.5 pg/mL (OR, 12.66; 95% CI 2.17-71.43) were independently associated with discordant MIBI-SPECT/CT results. CONCLUSION: MGD was most strongly associated with discordance between MIBI-SPECT/CT and intraoperative findings followed by a PTH level higher than 192.5 pg/mL and parathyroid lesion size of 12 mm or less. Surgeons should recognize these potential limitations, which may improve the preoperative procedure by encouraging further localization imaging and promptly facilitate intraoperative troubleshooting.

[Research on fennel used in Suoquan Pill].

Suoquan pill is composed of combined spicebush root, sharp-leaf glangal fruit and common yam rhizome. This recipe comes from Wei Shi Jia Cang Fang (, Wei's Family Stored Formulae) with an original name called "Gu Zhen Dan" (). In Wei Shi Jia Cang Fang, there is a note: take this medicine with some salt soup or salt wine. Before or after that chew dozens of fennel fruits. However, later ancient books were often confused with another prescription of the same name in the process of transmission. The most of editions of Fang Ji Xue(, Prescriptions of Chinese Materia Medica) follow the previous mistakes, most of which mist that "chew dozens of fennel fruits" . The investigations in this research have demonstrated that fennel fruits can be used to enhance the effect of reducing the amount of urine. It is suggested that when reprinting the textbook of Fang Ji Xue, "chew dozens of fennel fruits" should be indicated in the taking method following the original version of ancient books.
