Berberine hydrochloride is the main active ingredient of Coptis chinensis, which has demonstrated significant antibacterial activity against bacteria. However, the molecular mechanism underlying its effects is unclear in crabs. In this study, we used transcriptome sequencing to investigate the molecules involved in the therapeutic and defensive responses of Charybdis japonica infected with 105 colony-forming units (CFU)/L of Aeromonas hydrophila following treatment with berberine hydrochloride. A total of 5,409 differentially expressed genes were observed after exposure of C. japonicus for 72 h to 100 mg/L berberine hydrochloride, 100 mg/L berberine hydrochloride plus injection of 105 CFU/L A. hydrophila, and a control group injected with equal amount of physiological saline solution. Enrichment analysis revealed that these genes were involved in metabolism, cellular processes, signal transduction, and immune function. The transcriptomic results indicated that exposure to berberine hydrochloride activated glutathione metabolism, oxidative phosphorylation, fatty acid degradation, retinol metabolism, pyruvate metabolism, and the hypoxia-inducible factor 1 signaling pathway. Transcriptomic analysis and relative mRNA level analysis also identified acid hydrolase genes and phagosomal genes as key factors regulating the adaptation of acid berberine-infused C. japonicus to infection with A. hydrophila, Based on the ability of berberine hydrochloride to induce acid hydrolase and phagosomal gene expression, which can in turn remove bacteria, immersion in berberine hydrochloride may remove A. hydrophila and thus improve the survival of C. japonica. The results of this study provided a new scientific basis for the potential role of berberine hydrochloride in the immune mechanisms of crabs.

Berberine hydrochloride is an isoquinoline alkaloid, which has antitumoral, antibacterial, and antiviral activities in vivo and in vitro. Charybdis japonica is one of the main economic species of crab in Southeast Asia. We studied the molecular mechanism of oxidative stress in berberine hydrochloride-treated C. japonica infected with Aeromonas hydrophila. C. japonica were infected with A. hydrophila after being submerged in different concentrations (0, 100, 200, and 300 mg/L) of berberine hydrochloride for 48 h. The full-length cDNA of Prx6 and the ORFs of Prx5 and PXL2A were cloned. Prx6 and PXL2A each have one conserved domain, Cys44, and Cys81. The Prx5 conserved domain contains three important Cys loci, Cys75, Cys100, and Cys76. Prx6 was different from Prx5 and PXL2A in the Peroxiredoxin family. The transcription levels of PXL2A infected with A. hydrophila were all higher than the control. The transcription levels of C. japonica were further increased by adding berberine hydrochloride and were increased the highest at a concentration of 300 mg/L. The activities of glutathione peroxidase, superoxide dismutase, and catalase in the hepatopancreas of berberine hydrochloride-treated C. japonica infected with A. hydrophila were significantly increased compared with those only infected with A. hydrophila and the control group. The glutathione transferase activity in the hepatopancreas was significantly increased in berberine hydrochloride-treated C. japonica. The results of this study provide a new understanding of the potential role of berberine hydrochloride on the oxidative stress mechanisms of C. japonica.

We know that alloxan causes increased-permeability pulmonary edema and that alloxan generates oxygen radicals (H2O2, O2−, ·OH) in blood. Therefore, we hypothesize that alloxan-generated oxygen radicals damage pulmonary capillary endothelial cells, and, possibly, alveolar epithelial cells as well. We examined whether oxygen radical scavengers, such as catalase or dimethylsulfoxide (DMSO), protected against alloxaninduced pulmonary edema.Five dogs in each following group were anesthetized: control group: physiological saline (20ml/kg/h); alloxan group: physiological saline + alloxan (75mg/kg) bolus injection at the beginning of the experiment; catalase group: physiological saline + catalase (150,000u/kg) bolus injection before injection of alloxan; DMSO group: physiological saline + DMSO (0.4mg/kg) bolus injection before alloxan. All dogs had 30-min baseline period and 3-h intervention period. Hemodynamics and circulating substances were measured at the specific points of time. At the end of intervention period, the dogs were killed and had the lungs removed for electron microscopic study and lung water measurement with direct destructive method.

The aim of the analysis was for the first time to assess the expression of genes encoding IL-21 and IL-22 at the mRNA level in ovarian tumor specimens and the concentration of these parameters in serum and peritoneal fluid in patients with ovarian serous cancer. The levels of IL-21 and IL-22 transcripts were evaluated with the use of the real-time RT-qPCR. Enzyme-linked immunosorbent assay (ELISA) was used to determine the concentration of proteins. Quantitative analysis of IL-21 gene mRNA in the tumor tissue showed the highest activity in the G1 degree of histopathological differentiation and was higher in G1 compared to the control group. The concentration of IL-21 and IL-22 in the serum and in the peritoneal fluid of women with ovarian cancer varied depending on the degree of histopathological differentiation of the cancer and showed statistical variability compared to controls. The conducted studies have shown that the local and systemic changes in the immune system involving IL-21 and IL-22 indicate the participation of these parameters in the pathogenesis of ovarian cancer, and modulation in the IL-21/IL-22 system may prove useful in the development of new diagnostic and therapeutic strategies used in patients, which require further research.

The aim of the present study was to determine the effect of administration of Camelina sativa oil (CO) as a source of polyunsaturated fatty acids (PUFA) on bone parameters in ovariectomized rats (OVX). Overall, 40 10-week-old healthy female Wistar rats were divided into 4 groups with 10 animals in each. Rats in the control group (SHO) were subjected to a sham operation, whereas experimental rats (OVX) were ovariectomized. After a 7-day recovery period, the SHO the rats received orally 1 mL of physiological saline for the next 6 weeks. The OVX rats received orally 1 mL of physiological saline (OVX-PhS), 5 g/kg BW (OVX-CO5), or 9 g/kg BW (OVX-CO9) of camelina oil. The use of camelina oil had a significant effect on body weight, lean mass, and fat mass. The camelina oil administration suppressed the decrease in the values of some densitometric, tomographic, and mechanical parameters of femur caused by estrogen deficiency. The CO treatment increased significantly the serum level of osteocalcin and decreased the serum level of C-terminal telopeptide of type I collagen in the OVX rats. In conclusion, camelina oil exerts a positive osteotropic effect by inhibiting ovariectomy-induced adverse changes in bones. Camelina oil supplementation can be used as an efficient method for improving bone health in a disturbed state. However, further research must be carried out on other animal species supplemented with the oil.

Abstract Objective: This study explored the clinical effect of employing breast milk oral care for infants who underwent surgical correction of ventricular septal defect. Methods: A prospective randomised controlled study was conducted in a provincial hospital between January, 2020 and July, 2020 in China. Patients were randomly divided into an intervention group (breast milk oral care, n = 28) and a control group (physiological saline oral care, n = 28). The intervention group was given oral nursing using breast milk for infants in the early post-operative period, and the control group was given oral nursing using physiological saline. Related clinical data were recorded and analysed. Results: There were no significant differences in age, gender, weight, operation time, cardiopulmonary bypass time, or aortic cross-clamping time between the two groups. Compared with the physiological saline oral care group, the mechanical ventilation duration, the length of ICU stay in the breast milk oral care group were significantly shorter. The time of start feeding and total enteral nutrition were significantly earlier in the intervention group than those in the control group. The incidence of post-operative pneumonia in the breast milk oral care group was 3.6%, which was significantly lower than that of the physiological saline oral care group. Conclusion: The use of breast milk for oral care in infants who underwent surgical correction of VSD can reduce the incidence of post-operative pneumonia and promote the recovery of gastrointestinal function.

Objectives: We aimed to evaluate whether ultrasound (US) and microbubble-mediated delivery of Cluster of Differentiation 151 (CD151) could enhance the therapeutic effects of CD151 on myocardial infarction (MI). Methods: A rabbit model of MI was established by a modified Fujita method. Then, 50 MI rabbits were randomly divided into 5 groups, including G1 (CD151 plasmid and physiological saline in the presence of US); G2 (CD151 and Sonovue in the presence of US); G3 (CD151 and Sonovue in the absence of US); G4 (Sonovue in the absence of US), and a control group (physiological saline in the absence of US). After 14 days of treatment, the expression of CD151 was detected by Western blot. Besides, vessel density of peri-infarcted myocardium was measured by immunohistochemistry, and cardiac function was analyzed by echocardiography. Results: The rabbit model of MI was established successfully. CD151 injection increased the expression of CD151 and microvessel density in the myocardium of MI rabbits. Heart function was significantly improved by CD151, which exhibited increased left ventricular ejection fraction, left ventricular fractional shortening and a reduced Tei index. Besides, US Sonovue significantly increased the expression efficiency of CD151. Conclusion: US microbubble was an effective vector for CD151 delivery. CD151 might be an effective therapeutic target for MI.

<p>Two oil blends (sunflower/canola oils 85/15 (BL1) and canola/linseed oils 70/30 (BL2)), were prepared and enzymatically interesterified to be applied to surgically-induced wounds in rats. Following surgery, the animals were submitted to the Treatment with Physiological Saline (TPS) (control group), Blends (TBL), and Structured Lipids (TSL). The control group (TPS) received physiological saline solution for 15 days. In TBL, BL1 was administered during the inflammation phase (days 0-3) and BL2 in the tissue formation and remodeling phase (days 4-15). In TSL, Structured Lipid 1 (SL1) and Structured Lipid 2 (SL2) were used instead of BL1 and BL2, respectively. The aim of this study was to compare wound closure evolution among rats treated with the blends or structured lipids versus control rats treated with physiological saline. The wound healing process was evaluated by measuring the wound areas along the treatments and the concentrations of cytokines. An increase in the areas of wounds treated with the blends and structured lipids in the inflammatory phase was observed, followed by a steeper closure curve compared to wounds treated with physiological saline. The changes observed during the inflammatory phase suggest a potential therapeutic application in cutaneous wound healing which should be further investigated.</p>

In order to discuss the effects of nitrite on the density of hemocyte (DHC) and phenoloxidase (PO) activity in hemolymph of Charybdis japonica, the crabs were exposed to six nitrite-N groups (0, 2.0, 4.0, 6.0, 8.0 and 10.0 mg L-1 ambient nitrite-N concentrations). The DHC and PO activity was examined on days 1, 3, 5, 10 and 15 following the stress. Results showed that the two indexes appeared to have a decline trend after an initial ascent. After 1 day treatment, the DHC of five treatments were higher than that of the control group respectively, while the PO activity of 8.0 and 10.0 mg L-1 nitrite-N exposed group decreased compared with control. With time elapsed, the DHC of lower concentration nitrite-N exposed group increased faster, while the PO activity of higher concentration nitrite-N exposed group rised faster than other treatments. After 15-day stress, all parameters tested were lower than those of control group barring the DHC of 2.0 and 4.0 mg L-1 nitrite-N exposed group and the PO activity of 2.0, 4.0, and 6.0 mg L-1 nitrite-N exposed group.

Ketoprofen, a nonsteroidal anti-inflammatory drug (NSAID) has proven to exert anti-inflammatory, anti-proliferative and anti-angiogenic activities in both neoplastic and non-neoplastic conditions. We investigated the effects of this compound on tumor development in Swiss mice previously inoculated with Ehrlich tumor cells. To carry out this study the solid tumor was obtained from cells of the ascites fluid of Ehrlich tumor re-suspended in physiological saline to give 2.5x106cells in 0.05mL. After tumor inoculation, the animals were separated into two groups (n = 10). The animals treated with ketoprofen 0.1µg/100µL/animal were injected intraperitoneally at intervals of 24h for 10 consecutive days. Animals from the control group received saline. At the end of the experiment the mice were killed and the tumor removed. We analyzed tumor growth, histomorphological and immunohistochemical characteristics for CDC47 (cellular proliferation marker) and for CD31 (blood vessel marker). Animals treated with the ketoprofen 0.1µg/100µL/animal showed lower tumor growth. The treatment did not significantly influence the size of the areas of cancer, inflammation, necrosis and hemorrhage. Moreover, lower rates of tumor cell proliferation were observed in animals treated with ketoprofen compared with the untreated control group. The participation of ketoprofen in controlling tumor malignant cell proliferation would open prospects for its use in clinical and antineoplasic therapy.

Background Rabbit breeding has developed into a large-scale industry, and as such, the incidence of dermatophytosis in rabbits has become increasingly common. A rabbit model with Trichophyton mentagrophytes infection was established to study the changes within the immune responses after fungal infection. Methods After the T. mentagrophytes challenge on skin, pathogens on the skin were isolated from the rabbits in the fungal infection (FI) groups 20 days. Fungal observation under microscope were carried out. Identification of strains was achieved by polymerase chain reaction (PCR) using the CDR1 gene. The collected anticoagulant blood samples were analyzed for various blood cell parameters. The levels of antibodies, including IgM and IgA, cytokines, including IL-2, IL-6, and macrophage colony-stimulating factor (M-CSF), and soluble CD4 and CD8 in the serum of the FI group vs. the control group were determined independently. RNA isolation from blood samples and fluorescence-based quantitative PCR were carried out for the mRNA level of M-csf 20 days after fungal challenge. Results Our model resulted in typical symptoms of dermatophytosis on rabbit skin after challenged with fungus. Pathogens isolated from the infected rabbit skin were confirmed to be T. mentagrophytes by microscopic examination and PCR. The number of lymphocytes in the blood of the FI group was significantly decreased in comparison to the control group 2 days after the fungal challenge, but was significantly increased in comparison the control group 10 days after the fungal challenge (P < 0.01). Platelet counts of the FI group were significantly higher than in the control group at 2 (P < 0.05), 10 (P < 0.05), and 20 (P < 0.01) days after fungal challenge. The red blood cell distribution width of the FI group was significantly increased in comparison to that of the control group at 2, 10, and 20 days after fungal challenge (P < 0.01 for all days). The levels of antibodies (immunoglobulin (Ig) M and IgA (P < 0.01)), cytokines (interleukin (IL)-6 (P < 0.01), macrophage colony-stimulating factor (M-CSF) (P < 0.05)), and soluble CD4 (P < 0.01) and CD8 (P < 0.01) in the serum were significantly different between the FI and control groups. Serum M-csf mRNA level of the FI group was significantly higher than the control group 20 days after fungal challenge (P < 0.01). Conclusions This study demonstrates how the immune system responds to infection with T. mentagrophytes and provides potential targets for the prevention and treatment of dermatophytosis.
