OBJECTIVES: To study the impact of different induction remission therapies on the nutritional status of children with Crohn's disease (CD). METHODS: A retrospective analysis was conducted on the medical data of 188 children with CD who received induction remission therapy at the Children's Hospital, Zhejiang University School of Medicine from January 2013 to May 2023. The effects of three induction remission therapies-exclusive enteral nutrition (EEN), corticosteroids, and infliximab (IFX)-on height, weight, hemoglobin, and trace elements were compared. RESULTS: After induction remission therapy, the weight-for-age Z scores and serum levels of hemoglobin and albumin in all three groups significantly increased (P<0.05), while the height-for-age Z scores showed no change (P>0.05). The levels of folic acid, 25-hydroxy vitamin D, serum iron, and total calcium increased, and serum copper levels decreased in the EEN and IFX groups (P<0.05). Vitamin B₁₂ levels improved in the EEN group (P<0.05). CONCLUSIONS EEN, corticosteroids, and IFX may effectively improve the weight-for-age Z scores and serum levels of hemoglobin and albumin in children with CD. EEN and IFX seem to be superior to corticosteroid therapy in improving 25-hydroxy vitamin D, folic acid, serum iron, and total calcium levels.

OBJECTIVE: By analyzing the hormone secretion of the adenohypophysis, thyroid glands, gonads, and adrenal cortex in patients with hematological diseases before and after hematopoietic stem cell transplantation (HSCT), this study aims to preliminarily explore the effect of HSCT on patients' hormone secretion and glandular damage. METHODS: The baseline data of 209 hematological disease patients who underwent HSCT in our hospital from January 2019 to December 2023, as well as the data on the levels of hormones secreted by the adenohypophysis, thyroid glands, gonads and adrenal cortex before and after HSCT were collected, and the changes in hormone levels before and after transplantation were analyzed. RESULTS: After allogeneic HSCT, the levels of thyroid-stimulating hormone (TSH), triiodothyronine (T3), free triiodothyronine (FT3) and estradiol (E2) decreased, while the levels of luteinizing hormone (LH) and follicle- stimulating hormone (FSH) increased. The T3 level of patients with decreased TSH after transplantation was lower than that of those with increased TSH after transplantation. In female patients, the levels of prolactin (PRL), progesterone (Prog), and testosterone (Testo) decreased after HSCT. Testo and PRL decreased when there was a donor-recipient sex mismatch, and the levels of adrenocorticotropic hormone (ACTH) and cortisol (COR) decreased when the HLA matching was haploidentical. The levels of T3, FT3, and PRL decreased after autologous HSCT. In allogeneic HSCT patients, the levels of TSH, T4, T3, FT3, and ACTH in the group with graft-versus-host disease (GVHD) were significantly lower than those in the group without GVHD. Logistic regression analysis showed the changes in hormone levels after transplantation were not correlated with factors such as the patient's sex, age, or whether the blood types of the donor and the recipient are the same. CONCLUSION HSCT can affect the endocrine function of patients with hematological diseases, mainly affecting target glandular organs such as the thyroid, gonads, and adrenal glands, while the secretory function of the adenohypophysis is less affected.

Renal ischemia-reperfusion injury (IRI) is a major contributor to acute kidney injury (AKI), leading to substantial morbidity and mortality. Spexin (SPX), a 14-amino acid endogenous peptide involved in metabolic regulation and immune modulation, has not yet been studied in the context of chronic treatment and renal IRI. This study evaluated the effects of exogenous SPX on renal function, histopathological changes, and molecular pathways in both IRI-induced injured and healthy kidneys. Twenty-eight male BALB/c mice were divided into four groups: control, SPX, IRI, and SPX+IRI. IRI was induced by 30 minutes of bilateral renal ischemia followed by 6 hours of reperfusion. Renal injury markers, histopathological changes, inflammatory mediators, apoptotic markers, and fibrosis-related proteins were analyzed. SPX significantly exacerbated IRI-induced kidney injury by activating the Wnt/β-catenin signaling pathway and promoting the upregulation of pro-inflammatory, pro-apoptotic, and pro-fibrotic mediators. It is noteworthy that SPX exerted more severe deleterious nephrotoxic effects in the healthy kidney compared to those observed in the IRI-induced injured kidney. These findings indicate that chronic treatment with SPX administration may have intrinsic pro-inflammatory, pro-apoptotic and fibrotic properties, raising concerns about its therapeutic potential. Further research is needed to clarify its physiological role and therapeutic implications in kidney diseases.

OBJECTIVE: To examine the mechanistic of organochlorine-associated changes in lung function. METHODS: This study investigated 76 healthy older adults in Jinan, Shandong Province, over a five-month period. Personal exposure to organochlorines was quantified using wearable passive samplers, while inflammatory factors and thyroid hormones were analyzed from blood samples. Participants' lung function was evaluated. After stratifying participants according to their thyroid hormone levels, we analyzed the differential effects of organochlorine exposure on lung function and inflammatory factors across the low and high thyroid hormone groups. Mediation analysis was further conducted to elucidate the relationships among organochlorine exposures, inflammatory factors, and lung function. RESULTS: Bis (2-chloro-1-methylethyl) ether (BCIE), was negatively associated with forced vital capacity (FVC, -2.05%, 95% CI: -3.11% to -0.97%), and associated with changes in inflammatory factors such as interleukin (IL)-2, IL-7, IL-8, and IL-13 in the low thyroid hormone group. The mediation analysis indicated a mediating effect of IL-2 (15.63%, 95% CI: 0.91% to 44.64%) and IL-13 (13.94%, 95% CI: 0.52% to 41.07%) in the association between BCIE exposure and FVC. CONCLUSION Lung function and inflammatory factors exhibited an increased sensitivity to organochlorine exposure at lower thyroid hormone levels, with inflammatory factors potentially mediating the adverse effects of organochlorines on lung function.

The novel coronavirus disease (COVID-19) pandemic is emerging as a global health threat and shows a higher risk for men than women. Thus far, the studies on andrological consequences of COVID-19 are limited. To ascertain the consequences of COVID-19 on sperm parameters after recovery, we recruited 41 reproductive-aged male patients who had recovered from COVID-19, and analyzed their semen parameters and serum sex hormones at a median time of 56 days after hospital discharge. For longitudinal analysis, a second sampling was obtained from 22 of the 41 patients after a median time interval of 29 days from first sampling. Compared with controls who had not suffered from COVID-19, the total sperm count, sperm concentration, and percentages of motile and progressively motile spermatozoa in the patients were significantly lower at first sampling, while sperm vitality and morphology were not affected. The total sperm count, sperm concentration, and number of motile spermatozoa per ejaculate were significantly increased and the percentage of morphologically abnormal sperm was reduced at the second sampling compared with those at first in the 22 patients examined. Though there were higher prolactin and lower progesterone levels in patients at first sampling than those in controls, no significant alterations were detected for any sex hormones examined over time following COVID-19 recovery in the 22 patients. Although it should be interpreted carefully, these findings indicate an adverse but potentially reversible consequence of COVID-19 on sperm quality.

OBJECTIVE: To evaluate the effectiveness and possible mechanism of acupuncture treatment for negative emotion in patients with polycystic ovary syndrome (PCOS). METHODS: A total of 40 PCOS patients were randomly divided into an observation group and a control group, 20 cases in each one. Both groups received lifestyle interventions (exercise and diet guidance) on the 5th day of menstruation. On the basis of above treatment, the patients in the observation group received acupuncture at Guanyuan (CV 4), Zhongwan (CV 12), Guilai (ST 29), Futu (ST 32), Liangqiu (ST 34), Sanyinjiao (SP 6), Zusanli (ST 36), Hegu (LI 4), Shenmen (HT 7), Baihui (GV 20) as the main acupoints, and connected the electroacupuncture (continuous wave, 2 Hz, 30 min), once every other day, 3 times a week. The treatment for 1 month was as one course and 4 courses were required totally in both groups. Before and after treatment, the body mass index (BMI), ferriman-gallway (F-G) score, self-rating anxiety scale (SAS) score, self-rating depression scale (SDS) score, PCOS health-related quality of life questionnaire (PCOSQ) score were observed, meanwhile, serum sex hormone, including follicle-stimulating hormone (FSH), luteinizing hormone (LH), estrogen (E), progestin (P), prolactin (PRL), testosterone (T), sex hormone-binding globulin (SHBG) and free androgen index (FAI) levels, and serumβ-endorphin levels were detected. RESULTS: Compared with before treatment, the BMI, F-G score, SAS score, SDS score and serum FAI level were decreased and the PCOSQ score and the levels of serum SHBG andβ-endorphin were increased in the observation group after treatment (all <0.05). Compared with before treatment, the SDS score was decreased in the control group after treatment (<0.05). Compared with the control group, the F-G score, SDS score, SAS score, and serum FAI level were lower, and the PCOSQ score and serumβ-endorphin level were higher in the observation group after treatment (all <0.05). CONCLUSION Applying acupuncture to the treatment of patients with PCOS can effectively relieve anxiety and depression, and the mechanism may be related to the regulation on the levels of serumβ-endorphin and androgen.

PURPOSE: The aim of this study was to evaluate the relationships between cytokine and chemokine levels and the clinical severity of Mycoplasma pneumoniae pneumonia. METHODS: A retrospective analysis of clinical and laboratory parameters were performed. Serum levels of interleukin (IL)-6, IL-8, IL-10, IL-18, interferon-γ-inducible protein-10 (IP-10), macrophage inflammatory protein-1β, and tumor necrosis factor-α were measured. The severity of patients' clinical course and radiologic findings were also assessed. RESULTS: Seventy-two patients (35 males and 37 females) with a median age of 3.9 years (range, 1–16 years) were enrolled. Patients with lobar pneumonia (n=29) had significantly higher C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), and IL-18 values than those with broncho-interstitial pneumonia (n=43). However, the cytokine and chemokine values did not differ between the group that was treated with corticosteroids (n=31) and the one that was not (n=41). The CRP, ESR, lactate dehydrogenase (LDH), IL-18, and IP-10 values showed positive correlations with fever duration prior to admission. The CRP and ESR values were positively correlated with IL-18, and LDH, with IP-10 levels. CONCLUSIONS: CRP, ESR, LDH, IL-18, and IP-10 values were associated with the severity of the disease, manifesting lobar pneumonia or prolonged fever duration prior to admission.

BACKGROUND: Most of the blood-test samples are collected and carried in vacuum tubes. We have compared a newly developed vacuum tube, ‘Vacuon’ (Medion, Korea) and ‘BD Vacutainer®’ (BD, USA) in three common clinical assays, i.e., hematological, chemical, and immunological tests. METHODS: A sum of 60 healthy volunteers were recruited in our study and their peripheral blood samples were collected in the tubes of the two brands. EDTA-tube samples were evaluated using 25 hematological tests. Serum separating tube samples were analyzed for 24 chemical parameters and the 3 thyroid hormones. The results were statistically analyzed using the paired t-test and Bland-Altman plot. In addition, the assay outcomes at t=0 hr were compared with those at t=24±2 hr for each of the tubes. RESULTS: The assay results of 22 hematological parameters, 24 chemical parameters, and 3 thyroid hormones had a statistically significant correlation between the 2 brands of vacuum tubes (t=0 hr). Two hematological parameters (mean corpuscular hemoglobin concentration [MCHC] and cell hemoglobin concentration mean [CHCM]) showed higher mean values, while a hematological parameter (lobularity index [LI]) showed lower mean values in Vacuon than BD Vacutainer (t=0 hr). The results after 24 hr showed similarity between the 2 brands, with some inconsistent results in BD Vacutainer (Mean platelet volume [MPV], plateletcrit [Pct], eosinophil, calcium, and triiodothyronine) and Vacuon (MPV, hemoglobin distribution width [HDW], CHCM, Pct, eosinophil, and calcium). CONCLUSIONS: BD Vacutainer and Vacuon tube showed good statistical concordance rate with some exceptions in the hematological parameters (MCHC, CHCM, and LI).

Glycerol monolaurate (GML) has been widely used as an effective antibacterial emulsifier in the food industry. A total of 360 44-week-old Hy-Line brown laying hens were randomly distributed into four groups each with six replicates of 15 birds, and fed with corn-soybean-meal-based diets supplemented with 0, 0.15, 0.30, and 0.45 g/kg GML, respectively. Our results showed that 0.15, 0.30, and 0.45 g/kg GML treatments significantly decreased feed conversion ratios (FCRs) by 2.65%, 7.08%, and 3.54%, respectively, and significantly increased the laying rates and average egg weights. For egg quality, GML drastically increased albumen height and Haugh units, and enhanced yolk color. Notably, GML increased the concentrations of polyunsaturated and monounsaturated fatty acids and reduced the concentration of total saturated fatty acids in the yolk. The albumen composition was also significantly modified, with an increase of 1.02% in total protein content, and increased contents of His (4.55%) and Glu (2.02%) under the 0.30 g/kg GML treatment. Additionally, GML treatments had positive effects on the lipid metabolism of laying hens, including lowering the serum triglyceride and total cholesterol levels and reducing fat deposition in abdominal adipose tissue. Intestinal morphology was also improved by GML treatment, with increased villus length and villus height to crypt depth ratio. Our data demonstrated that GML supplementation of laying hens could have beneficial effects on both their productivity and physiological properties, which indicates the potential application of GML as a functional feed additive and gives us a new insight into this traditional food additive.
