Eucalyptol, limonene and pinene enteric capsules attenuate airway inflammation and obstruction in lipopolysaccharide-induced chronic bronchitis rat model via TLR4 signaling inhibition. Int Immunopharmacol 2024; 129:111571. [PMID: 38309095 DOI: 10.1016/j.intimp.2024.111571] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2023] [Revised: 01/05/2024] [Accepted: 01/17/2024] [Indexed: 02/05/2024]
Abstract
BACKGROUND Chronic bronchitis (CB), a type of chronic obstructive pulmonary disease (COPD), poses a significant global health burden owing to its high morbidity and mortality rates. Eucalyptol, limonene and pinene enteric capsules (ELPs) are clinically used as expectorants to treat various respiratory diseases, including CB, but their acting mechanisms remain unclear. In this study, we investigated the anti-CB effects of ELP in a rat model of lipopolysaccharide (LPS)-induced CB. The molecular mechanisms underlying its inhibitory effects on airway inflammation were further explored in LPS-stimulated Beas-2B cells. METHODS ELP was characterized using gas chromatography. The production of inflammatory mediators in bronchoalveolar lavage fluid (BALF) was determined using an enzyme-linked immunosorbent assay. The expression of MUC5AC, MUC5B, and p-p65 in the lung tissue was measured using immunohistochemical staining. The gene expression of inflammatory mediators was determined using qRT-PCR. The expression levels of the target proteins were detected by western blotting. Nuclear localization of p65 was determined using an immunofluorescence assay. RESULTS Compared to the CB model rats, ELP-treated rats showed reduced airway resistance, inflammation, and goblet cell hyperplasia. In BALF, ELP decreased the levels of inflammatory mediators, including TNF-α, IL-6, MIP-1α, and CCL5. ELP also suppressed LPS-induced elevation of MUC5AC, MUC5B, and p-p65 in the lung tissue. The metabolic pathway changes caused by LPS challenge were improved by ELP treatment. In LPS-exposed Beas-2B cells, ELP treatment inhibited the expression of TNFA, IL6, CCL5, MCP1, and MIP2A and decreased the phospho-levels of toll-like receptor 4 (TLR4) signaling-related proteins, including p-p38, p-JNK, p-ERK, p-TBK1, p-IKKα/β, p-IκB, p-p65, and p-c-Jun. ELP also hindered the nuclear translocation of p65, c-Jun, and IRF3. CONCLUSIONS This study showed that ELP has a potential therapeutic effect in LPS-induced CB rat model, possibly by suppressing TLR4 signaling. These results justify the clinical use of ELP for the treatment of pulmonary inflammatory diseases.

Abstract
Objective: To investigate the levels of sex hormone and fertility in female patients after hematopoietic stem cell transplantation (HSCT), as well as their correlation with conditioning regimens, and analyse the effect of hormone replacement therapy (HRT) in young women after HSCT. Methods: Retrospective case series study. The clinical data of 147 women who underwent HSCT in the First Affiliated Hospital of Soochow University from January 2010 to January 2021 were retrospectively analyzed. The sex hormone levels were measured and followed-up, and the survival, menstrual fertility and the use of HRT of the patients were also followed-up. The sex hormone levels were measured after transplantation, and the ovarian function was evaluated. Independent sample t test and χ2 test were used for comparison between the two groups. Results: The median age of the 147 patients was 26 (range, 10-45) years. Of them, 135 patients received allogeneic HSCT and 12 patients received autologous HSCT. Furthermore, 129 patients received myeloablative conditioning, and 18 patients received reduced conditioning dose. The median follow-up time was 50 months (range, 18-134 months). Five patients died of disease recurrence during follow-up. Of the 54 patients with subcutaneous injection of zoladex, three recovered menstruation spontaneously after transplantation, and all of them were myeloablative conditioning patients, one patient gave birth to twins through assisted reproductive technology. Ninety-three patients did not use zoladex before conditioning, two patients with aplastic anemia with non-myeloablative transplantation resumed menstruation spontaneously, and conceived naturally. The level of follicle stimulating hormone after transplantation in patients receiving myeloablative conditioning regimen was significantly higher than that in patients receiving reduced-dose conditioning regimen [(95.28±3.94) U/L vs. (71.85±10.72) U/L, P=0.039]. Among 147 patients, 122 patients developed premature ovarian failure, 83 patients received sex hormone replacement therapy after transplantation, and 76 patients recovered menstruation and improved endocrine function. Conclusions: The incidence of premature ovarian failure is high in female patients after HSCT, and patients have a chance at natural conception. Reducing the dose of conditioning regimen and the application of zoladex before transplantation can reduce ovarian of conditioning drugs. HRT after transplantation can partially improve the endocrine function of patients.

Abstract
Objective: To assess the efficacy and safety of polymyxin B in neutropenic patients with hematologic disorders who had refractory gram-negative bacterial bloodstream infection. Methods: From August 2021 to July 2022, we retrospectively analyzed neutropenic patients with refractory gram-negative bacterial bloodstream infection who were treated with polymyxin B in the Department of Hematology of the First Affiliated Hospital of the Soochow University between August 2021 to July 2022. The cumulative response rate was then computed. Results: The study included 27 neutropenic patients with refractory gram-negative bacterial bloodstream infections. Polymyxin B therapy was effective in 22 of 27 patients. The median time between the onset of fever and the delivery of polymyxin B was 3 days [interquartile range (IQR) : 2-5]. The median duration of polymyxin B treatment was 7 days (IQR: 5-11). Polymyxin B therapy had a median antipyretic time of 37 h (IQR: 32-70). The incidence of acute renal dysfunction was 14.8% (four out of 27 cases), all classified as "injury" according to RIFLE criteria. The incidence of hyperpigmentation was 59.3%. Conclusion: Polymyxin B is a viable treatment option for granulocytopenia patients with refractory gram-negative bacterial bloodstream infections.

Abstract
Objective: To observe the efficacy and adverse reactions of a combination therapy regimen based on bortezomib and glucocorticoids in recurrent/refractory immune thrombocytopenic purpura (iTTP) . Methods: Six patients with recurrent/refractory TTP were included and treated with a glucocorticoid and two courses of bortezomib-based regimen. The clinical remission status of patients, changes in ADAMTS13 activity/ADAMTS13 inhibitor, and the occurrence of treatment-related adverse reactions were observed. Results: Of the 6 patients, 2 were males and 4 were females, with a median age of 21.5 (18-68) years. Refractory TTP was found in 1 case and recurrent TTP in 5 cases. Glucocorticoids were administered with reference to prednisone at 1 mg·kg(-1)·d(-1), and gradually reduced in dosage after achieving clinical remission. Bortezomib is subcutaneously administered at 1.3 mg/m(2) on days 1, 4, 8, and 11 with a 28-day treatment course consisting of 2 courses. Six patients achieved clinical remission after receiving bortezomib as the main treatment. ADMATS13 activity returned to normal in all patients with TTP after treatment, and the ADAMTS13 inhibitor turned negative. Thrombocytopenia is the most common adverse reaction after treatment, with other adverse reactions, including peripheral neuritis and abdominal pain, but ultimately all patients returned to normal. In a median follow-up of 26 (9-41) months, 5 patients maintained sustained remission, and 1 patient relapsed after 16 months of bortezomib treatment. Conclusion: Combination therapy of bortezomib and glucocorticoids has a satisfactory therapeutic effect and controllable adverse reactions for recurrent/refractory iTTP.

Abstract
Objective: To examine the survival rates and clinical characteristics of people with newly discovered non-M(3) acute myeloid leukemia (AML) who carry the ASXL1 gene mutation. Methods: From January 2016 to April 2021, the clinical information of patients with newly diagnosed non-M(3) AML at Shandong University's Qilu Hospital was retrospectively examined, and their clinical characteristics and survival were compared and analyzed. Gene mutation was detected by next-generation sequencing. Results: ① The study included 256 AML patients who were initially diagnosed and had complete data, including 47 cases of ASXL1 gene mutation-positive (ASXL1(+)) patients and 209 cases of ASXL1 gene mutation-negative (ASXL1(-)) patients. All patients were divided into three groups: elderly (≥60 years old, n=92) , middle-aged (45-59 years old, n=92) , and young (≤44 years old, n=72) . ②WBC, and age were higher in patients with ASXL1 mutations compared to ASXL1(-) patients, while complete response after the first round of treatment (CR(1)) was lower (P<0.05) . In the elderly group, WBC and the proportion of aberrant cells in nuclear cells in ASXL1(+) patients were higher than those in ASXL1(-) patients (P<0.05) . In the young group, the WBC of ASXL1(+) patients was higher than that of ASXL1(-) patients (z=-2.314, P=0.021) . ③IDH2 mutation and ASXL1 mutation was related (P=0.018, r=0.34) . In ASXL1(+) patients, the proportion of peripheral blasts in the high VAF group (VAF>40% ) was higher than that in the low VAF group (VAF<20% ) , and the proportion of aberrant nuclear cells was higher in the duplication and replacement mutation patients than in the deletion mutation patients (P<0.05) . ④The overall survival (OS) and progression-free survival (PFS) of ASXL1(+) patients were shorter than those of ASXL1(-) patients (median, 10 months vs 20 months, 10 months vs 17 months; P<0.05) . The proportion number of aberrant cells in nuclear cells (≥20% ) , complex karyotypes, and TET2 mutation were all independent risk variables that had an impact on the prognosis of ASXL1(+) patients, according to multivariate analysis (P<0.05) . Conclusion: ASXL1-mutated non-M(3) AML patients have higher WBC in peripheral blood, a higher proportion of aberrant cells in nuclear cells, lower CR(1) rate, and shorter OS and PFS. Additionally, a poor prognosis is linked to higher VAF, duplication, and substitution mutations in the ASXL1 gene, as well as the high proportion of aberrant cells in nuclear cells, complex karyotype, and TET2 mutation.

Abstract
Objective: The Chinese Anti-Cancer Association Genitourinary Cancer Committee Prostate Cancer Working Group released Consensus of prostate cancer (PCa) screening in 2017. This program aims to evaluate the methods and significance of prostate cancer precision screening in high risk population. Methods: A total of 2 159 eligible males enrolled from 13 community centers and 3 screening centers received PSA test from April 2017 to August 2018. Prostate-specific antigen (PSA) determination in serum with a cut-off of ≥4.0 ng/ml was the main screening test and indication for biopsy. The interviewer-administered questionnaire covered demographic characteristics and environmental exposure factors. The associations between these factors and prostate cancer risk were determined by multivariable unconditional logistic regression models. Results: Altogether, 271 cases (12.6%) had a confirmed PSA increase ≥ 4.0 μg/L (median 9.1, range 4.0-25.0). Subsequently, 57 subjects (21.0%) out of the 271 PSA-suspicious men underwent prostate biopsy, and 34 (59.6%) were confirmed as prostate cancer. Until now, the overall prostate cancer incidence in the first screening round was1.57%. There were no statistical differences in the distributions of PSA-suspicious and prostate cancer incidence between community centers and screening centers (P=0.578 and 0.735). Age (OR: 2.63; 95%CI: 1.84-3.75, P<0.001) and chronic prostatitis history (OR: 2.02; 95%CI: 1.55-2.63, P<0.001) were significantly associated with PSA level. After adjustment for these factors, older age (OR: 4.04; 95%CI: 1.71-9.59, P=0.002) and statins use (OR: 3.09; 95%CI: 1.25-7.69, P=0.015) were associated with an elevated risk of PCa. Conclusions: It is of substantial significance to screen prostate cancer in high risk population. Both community centers and screening centers methods are effective. Although largely underestimated, the incidence of PCa in the targeted Chinese population is higher than expected. Older men have a high risk of harboring PCa. Our study suggests a decreased risk of PCa in men with statins use. Prostate Cancer Precision Screening is promising to improve prostate cancer survival in China.

Abstract
Objective: To investigate the relationship between serum 25-hydroxyvitamin D[25(OH) D] levels and idiopathic benign paroxysmal positional vertigo (BPPV) in female patients. Methods: A total of 67 women diagnosed with idiopathic BPPV were selected as the study group between January and December 2016 in Ningbo No.2 Hospital, and 95 healthy women without a history of vertigo or dizziness were selected as the control group. The data of height, weight, histories of hypertension and diabetes mellitus were collected, and serum 25(OH) D levels were measured. The number of the recurrence and canalith repositioning maneuvers were recorded during the one-year follow-up. Results: No significant differences of age, body mass index, histories of hypertension and diabetes mellitus between patients with BPPV and healthy controls (all P>0.05) .The serum 25 (OH) D levels were significantly lower in patients with idiopathic BPPV than in healthy controls [(50.56±13.36) nmol/L vs (56.55±16.21) nmol/L, t=-2.485, P=0.014]. BPPV patients with low level of 25(OH) D showed a significant increase in the number of canalith repositioning maneuvers required and the recurrence rate. The regression analyses demonstrated that 25(OH)D deficiency was associated with BPPV with an odds ratio of 2.054 (95% CI: 1.088-3.877, P=0.026). Conclusion: 25(OH) D deficiency may be a risk factor of BPPV.

Abstract
Objective: To analyze the bone mineral density and serum osteocalcin levels in postmenopausal women with idiopathic benign paroxysmal positional vertigo. Methods: A total of 64 postmenopausal women with idiopathic BPPV were selected as the study group, and 98 postmenopausal healthy women were selected as the control group. Bone mineral density and serum osteocalcin levels were analyzed and compared between the groups.χ(2) test was used for numeration data and t test was used for measurement data. Results: The prevalence of osteoporosis or osteopenia in BPPV group 67.2% (43/64) was significantly higher than that in the control group 51.0% (50/98) (χ(2)=4.139, P=0.042). Among BPPV subjects, there was a negative correlation between osteocalcin and bone density T (r=-0.469, P<0.001). Osteocalcin was found in normal bone mass subgroup (13.61±4.32)μg/L, decreased bone mass subgroup (17.49±7.61)μg/L, and osteoporosis subgroup (20.83±6.72)μg/L, respectively, and the difference was statistically significant (F=5.39, P=0.007). Conclusions: Bone mineral density in BPPV group is lower than that in control group. The lower the bone mineral density of the patients, the higher the osteocalcin in BPPV group.

Abstract
To assess the homology and phylogenetic relationship between porcine epidemic diarrhea virus (PEDV) Anhui strains and other PEDV strains, molecular homology and phylogenetic analyses of Anhui PEDV field strains were compared with those of reference strains. The results revealed that the M and N genes of PEDV were 681 and 1326 bp long, respectively. The nucleotide sequences of the N genes of Anhui PEDV strains were 95.9-99.9% homologous with each other, and the deduced amino acid sequences were 92.5-99.8% homologous. Compared with the PEDV reference strains, the Anhui PEDV field strains had 94.1-99.5% nucleotide sequence homology in the N gene and 91.2-97.5% amino acid mutation homology in the N protein. The nucleotide sequences of the M genes of Anhui PEDV were 98.3-100% homologous, and the deduced amino acid sequences were 96.5-99.6% homologous. Compared with the PEDV reference strains, the Anhui PEDV field strains had 96.9-100% nucleotide sequence homology in the M gene and 96.5-99.6% amino acid homology in the M protein. The Anhui strains were genetically similar to USA strains (USA/Iowa/16465/2013 and USA/Indiana/17846/2013) but different from European (CV777;Br1/7), Korean (Chinju99), and Japanese (83p-5) strains.

Abstract
Dexamethasone has been widely used before general anesthesia induction. However, previous studies have found that a pre-induction bolus dose of dexamethasone sometimes causes perineal pruritus. We hypothesized that an appropriate prolongation of the injection time might suppress dexamethasone-induced perineal pruritus. Four hundred patients requiring general anaesthesia were randomly allocated into four groups: group I receiving 2 ml dexamethasone (5 mg/ml); group II receiving 4 ml dexamethasone (2.5mg/ml); group III receiving 10 ml dexamethasone (1 mg/ml); and group IV receiving 20 ml dexamethasone (0.5 mg/ml). Dexamethasone was diluted with 0.9% sodium chloride. The injection time of dexamethasone was 5s in groups I, II and III; while the injection time of dexamethasone was 30s in group IV. Occurrence of perineal pruritus was significantly reduced in Group IV (0% vs 38%, 32% and 12% in Groups I, II and III, respectively, p < 0.05). The incidence was higher in females than in males (p < 0.05). The duration of perineal pruritus was longer in females than in males in groups I, II and III (p < 0.05). We conclude that the dilution of dexamethasone to 0.5 mg/ml with 0.9% sodium chloride combined with prolonged injection time to 30 s eliminates dexamethasone-induced perineal pruritus.

Abstract
BACKGROUND AND AIMS The major risk factors for acute hepatitis B (AHB) in China and the viral factors determining the progression from acute to chronic hepatitis B remain largely unknown. METHODS Epidemiological studies within a population-based surveillance for AHB in adults were performed in Shanghai, China, including 294 patients, 588 matched controls and 572 family members of the patients. RESULTS Invasive medical procedures, household contact with hepatitis B virus (HBV) carriers, body care and beauty treatments, and lack of HBV vaccination were independently associated with AHB. Among those risks, pedicure in bath centres emerged. Sixty-eight of 128 patients with AHB were genotyped including 33 with HBV B2 and 35 with HBV C2. Twenty-five (8.50%) of the 294 patients, including 20 with HBV C2 and 5 with HBV B2 (p = 0.013), progressed to chronic infection. Multivariate analysis showed that HBV C2 was independently associated with chronicification of AHB. Patients with HBV B2 were younger and there was a higher proportion of women than those with HBV C2. The prevalence of HBV B2 was higher in the patients than in neighbourhood chronic carriers. The chronic carriers with HBV B2 showed higher viral loads, higher hepatitis B e antigen (HBeAg) seropositivity, and with higher proportion in men than those with HBV C2, implying that sexual contact plays a role in the transmission of HBV B2. Phylogenetic analysis showed that HBV C2 was frequently involved in transmissions within households. CONCLUSIONS Despite lower viral load and HBeAg status in the chronic carriers, HBV C2 was more prone to causing chronic infection than was HBV B2.

Abstract
Effects of EGb on cultured bovine aortic endothelial cells (BAEC) damaged by lysophosphatidylcholine (LPC) were investigated. When endothelial cells were incubated with LPC (2.5 micrograms.ml-1) for 24 h, the endothelial cells turned round pyknotic, exfoliated and broken, and the contents of malondialdehyde (MDA), lactate dehydrogenase (LDH) and plasminogen activator inhibitor (PAI) were markedly increased and the superoxide dismutase (SOD) activity was inhibited. Treatment with EGb at concentrations of 125 and 250 micrograms.ml-1, caused a reduction in MDA, LDH and PAI contents, while the SOD activity in the medium was increased and the morphologically damaged BAECs were alleviated. These results suggest that EGb afforded protection against BAECs damages induced by LPC and that the protective effect of EGb may be due to anti-lipid peroxidation via free-radical scavenging activity.

Abstract
Perinatal cytomegalovirus (CMV) infection was studied, using method of CMV-IgM ELISA, in 256 pregnant women at different periods and in the cord blood of 84 babies born by CMV positive mothers. Results showed that in 42 cases at early and midtrimester pregnancy, 17 were CMV-IgM positive with an infection rate of 40.48%. Among the 214 women at late pregnancy, 84 were positive (39.25%). There was a higher prevalence of perinatal morbidity, neonatal asphyxia, malformation, intrauterine death, and poor obstetrical outcome in the CMV positive mothers as compared with the CMV negative group (P < 0.01). This study showed that the presence of CMV-IgM indicated a recent or recurrent CMV infection during pregnancy and the babies should be carefully monitored.
