Objective To study the effects of acute cadmium exposure on the immune function of white blood cells (WBC), plasma interleukin-2 (IL-2) and cortisol levels in rats. Methods Thirty-six male rats were randomly divided into three groups averagely. The control group (group C) and two experimental groups(groupⅠand group Ⅱ) were respectively exposed to 0, 0.5, 1.0 mg / kg body weight (BW) cadmium for 7 days by intraperitoneal injection. Blood samples of the rats were collected on the 4th and 7th day after administration of cadmium respectively and the related parameters were analyzed. Results The BW of rats in groupⅠand group Ⅱ were significantly lower than that of the group C. The WBC counts of two experimental groups were higher than that of the control group. Higher percentage of neutrophiles and lower percentage of lymphocytes were observed in rats of group Ⅰ and Ⅱ on the 7th day after cadmium exposure, while no obvious variations in monocytes(%), eosinophiles(%) and basophiles(%)were observed among the three groups. Blood T-lymphocyte(%) and IL-2 levels in rats of groupⅠandⅡdecreased on the 4th and 7th day after cadmium exposure respectively, while B-lymphocyte(%) increased on the contrary. Plasma cortisol levels in rats of groupⅠ and groupⅡ were higher than that of the group C on the 7th day after cadmium exposure. Conclusion The results showed that acute cadmium exposure could affect the WBC immune function and result in the defect of cellular immune function as well as significant change of adrenal cortex endocrine activities.

Objective To investigate the effects of salinomycin on the cell proliferation and epithelial-mesenchymal transition (EMT) of MCF-7 mammosphere (MCF-7 MS). Methods Breast cancer MCF-7 cells were cultured in suspension in serum-free medium to obtain MCF-7 MS. The cell viability of MCF-7 MS cells treated with serial concentrations of 0, 10, 30, 100, 300, 1 000, 3 000 and 10 000 nmol/L of salinomycin for 24 hours were detected by CCK-8 assay. The half maximal inhibitory concentration (IC50) was calculated. Western blot analysis was performed to detect the expression levels of E-cadherin and Snail in MCF-7 MS cells treated with 30 nmol/L and 60 nmol/L salinomycin. The same capacity of DMSO was added to MCF-7 MS as control group. The xenograft tumors from MCF-7 MS transplant mice were divided into control group (the same capacity of normal saline) and salinomycin group (5 mg/kg salinomycin), then the expressions of E-cadherin and Snail were dectected by immunohistochemical staining. Results With the increased concentration of salinomycin, the cell survival rate of MCF-7 MS cells decreased (P<0.05). The IC50 after 24 h-treatment was 989 nmol/L. Both 30 and 60 nmol/L of salinomycin increased the expression of E-cadherin and decreased the expression of Snail compared with control group. In addition, 60 nmol/L treatment group showed more significant effect (P<0.05). In xenograft tumors from MCF-7 MS transplant mice, the expression of Snail decreased, and E-cadherin increased in salinomycin treatment group compared with control group (P<0.01). Conclusion Salinomycin can inhibit the cell proliferation and EMT in MCF-7 MS cells, which is a potential drug to target cancer stem cells.

Objective To explore the clinical signiifcance of combined detection of thyroid stimulating hormone (TSH) and free thyroxin (FT4) in dried blood spots in screening for congenital hypothyroidism (CH) in neonates. Methods The TSH and FT4 levels in dried blood spot were measured by time-resolved lfuorescence immunity in live born neonates from June to December 2013. If the screening was positive, the blood was drawn and the serum TSH and FT4 were measured and compared with the results from dried blood spots. Results In a total of 31 199 neonates screened, 12 cases were diagnosed with CH and the prevalence rate of CH was 1/2 600;4 cases were hyperthyropinemia and no pituitary CH was detected. There was no signiifcant difference between TSH or FT4 levels in dried blood spot and those in serum in neonates diagnosed with CH (P>0.05). Conclusions Combined detection of TSH and FT4 in dried blood spot can be used for neonatal screening of CH. It can be applied for early distinguishing CH from hyperthyropinemia, and also helpful for early diagnosis and treatment of central CH.

Objective: To study the protective effect in CCl4-induced liver injury by organoselenium from Se-enriched lactobacillus. Methods: (1) In the first series, forty-five animals were randomly divided into control (C) group, CCl4 group, CCl4 plus organoselenium group (CCl4-Se group). The liver injury was induced by abdominal injection of CCl4 every other day for 4 w. Changes of GSH-Px, CAT and SOD activities as well as MDA content in liver were estimated in the 2nd and 4th week after CCl4 injection respectively. (2) In the second series, forty-eight mice were randomly divided into C group, CCl4 group, CCl4 plus low dose organoselenium group (CCl4-LSe group) and CCl4 plus high dose organoselenium group (CCl4-HSe group). Changes of hepatocyte [Ca2+]i in animals in every group were investigated by means of confocal laser microscope on the 4th and 8th day after CCl4 injection respectively. Results: During the entire experimental period, liver MDA of CCl4 group was markedly superior to that of C and CCl4-Se groups, and the level of latter two groups was very close. The GSH-Px and CAT activities were higher in CCl4-Se group than in CCl4 group,but lower than that of C group. There were higher SOD activities in C and CCl4-Se groups compared to that in CCl4 group though without obvious difference. Average fluorescence pixels of hepatocyte [Ca2+]i in CCl4 group was 2.8 and 5.5 times higher than that of group C in the 4th and 8th day respectively,while those in CCl4-Se groups were significantly lower than those of CCl4 group, and close to C group. Conclusions: Organoselenium from Se-enriched lactobacillus, can protect hepatocyte [Ca2+]i homeostasis by reducing lipid peroxidation after CCl4 exposure.

Objective To study the effects of ShenhongTongluo Granules on blood lipids, inflammatory related factors and oxidative stress-related indexes in rabbit atherosclerosis model, and to explore the mechanism of Shenhongtongluo Granules on atherosclerosis. Methods 70 healthy male New Zealand white rabbits were randomly divided into blank control group, model group, aspirin combined with simvastatin group, aspirin group, simvastatin group, Shenhongtongluo Granule prevention group, and Shenhongtongluo Granule treatment group. The rabbit atherosclerosis model was established by lipidforage diet combined with immune stimulation, and the blank group was fed with commonforage. The Shenhongtongluo Granule prevention group was given Shenhongtongluo Granule at the beginning of modeling, and the other intervention groups were given the corresponding drugs after the successful modeling. Before and after modeling, lipid changes were checked in each group, including total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), superoxide dismutase activity (SOD) and malondialde-hyde (MDA) in the serum. The aorta of the model group was separated and oil red O staining was performed to observe the pathological and morphological changes of the aorta. Western blotting and reverse transcription polymerase chain reaction (RT-PCR) were used to detect the expression of Nox4 and p22phox. Western blotting was used to detect the expression of TLR4 and NF-κB protein in aorta. Results Twelve weeks after modeling, atheromatous plaques were obviously observed on the aorta stained with oil red O, indicating successful atherosclerosis modeling. Compared with the blank control group, TC, TG, and LDL-C in the serum of the atherosclerosis model group were significantly increased (all P<0.05). Compared with the model group, the atherosclerotic plaques in the Shenhongtongluo Granule prevention and the treatment groups were significantly reduced , the levels of TC , TG , LDL-C in serum were decreased, and the levels of SOD were increased, and MDA levels were reduced (all P<0.05). The expressions of TLR4, NF-κB, Nox4, and p22phox in the aorta of Shenhongtongluo Granule prevention group were significantly reduced (all P<0.05). Conclusions Shenhongtongluo Granules can inhibit the formation of atheromatous plaques, have a good effect on regulating blood lipids, and can improve the ability of anti-oxidative stress, and have a good preventive and therapeutic effect.

Objective To explore the feasibility and guiding value of point-of-care ultrasound (PoCUS) in evaluating gastric residual volume (GRV) in the course of implementing enteral nutrition (EN) in patients with neurological critical illness. Methods Ninety patients with critical neurological diseases necessary for EN were admitted to the Department of Intensive Care Unit (ICU) of Taizhou Hospital of Integrated Traditional Chinese and Western Medicine from March 1, 2017 to September 30, 2018 were selected, and they were randomly divided into a GRV extraction group (control group) and a PoCUS GRV group (study group), 45 patients in each group. Both groups were fed with Ruidai nutrient solution by nasogastric pump at a rate of 18 hours per day to persistently administer the target feeding volume for consecutive 7 days. The differences in tolerance of EN, the incidence of feeding interruption, the daily volume of EN fluid, the ratio of reaching total enteral nutrition (TEN) and the levels of serum albumin (Alb), prealbumin (PA) and prognosis were compared between the two groups. Results The incidences of reflux and wrong aspiration in the study group were significantly lower than those in the control group [8.9% (4/45) vs. 24.4% (11/45) and 4.4% (2/45) vs. 17.8% (8/45), both P < 0.05]. The EN liquid volume, ratio of reaching TEN, Alb and PA levels in the study group were significantly higher than those in the control group [EN liquid volume (mL/d): 944.6±277.1 vs. 783.7±230.5, the ratio of TEN: 86.7% (39/45) vs. 68.9% (31/45), Alb (g/L): 30.6±3.0 vs. 29.4±2.4, PA (g/L): 280.5±31.8 vs. 267.7±28.4, all P < 0.05]. The incidence of diarrhea [15.6% (7/45) vs. 13.3% (6/45)], the incidence of feeding interruption [8.9% (4/45) vs. 13.3% (6/45)], the length of stay in ICU (days: 10.4±6.2 vs. 8.3 ±5.4), the mortality [8.9% (4/45) vs. 13.3% (6/45)] had no significant differences between the two groups (all P > 0.05). Conclusion Evaluating GRV by PoCUS to adjust EN implementation plan can reduce the incidences of reflux and wrong aspiration and increase the EN intake.
