OBJECTIVE:
To investigate the expression and significance of B and T lymphocyte weakening factor (BTLA) in patients with chronic myelomonocytic leukemia (CMML).
METHODS:
Real-time PCR was used to detect the expression of BTLA and its ligand HVEM mRNA in 11 patients with chronic myelomonocytic leukemia and 11 normal donors. Flow cytometry was used to detect expression of BTLA and its HVEM on the cell surface of peripheral blood T lymphocytes and γδ T cells.
RESULTS:
The median values of BTLA and its ligand HVEM mRNA expression in peripheral blood of patients with CMML were 0.009% and 559.4%, respectively, which were significantly lower than those of normal controls (0.053% and 1031%)(P<0.001). The expression level of BTLA and HVEM on cell surface of peripheral lymphocytes was not significantly different from that in normal controls (P=0.3031 and 0.2576), however, the proportion of peripheral blood T lymphocytes in patients with CMML (median: 37.73%) was significantly lower than that in controls (median 69.23%)(P=0.0005). The expression of BTLA on the surface of γδ T cells in peripheral blood of patients with CMML (median: 23.26%) was significantly lower than that of the controls (median: 52.64%) (P<0.05), and there was no significant abnormality in HVEM expression (P=0.2791).
CONCLUSION
The expression of BTLA and its ligand HVEM, the proportion of T lymphocytes and the expression of BTLA on the surface of γδ T cells in patients with CMML are reduced. The effects of these abnormalities on T cell function and prognosis and efficacy of patients need to be further observed.

Objective:
To study the occurrence of sarcopenia in patients with liver cirrhosis, and to explore their risk factors and impact on clinical outcomes.
Methods:
199 hospitalized cases with liver cirrhosis were collected for nutritional risk screening, anthropometric measurement and blood biochemical examination. The body composition analysis was measured based on the skeletal muscle content of the four limbs to calculate the appendicular skeletal muscle mass index (ASMI). Patients were divided into sarcopenia and non-sarcopenia group and the relevant indexes of both groups were compared to screen for factors affecting the occurrence of sarcopenia. During the follow-up of 48 months, the survival and complications of the both groups were compared. Statistical analysis was performed using t-test, χ2 test and logistic regression analysis in terms of different data.
Results:
The incidence of sarcopenia in cirrhosis was 36.7%, with the highest prevalence in patients with recurrent hepatic encephalopathy (62.5%), followed by patients with abdominal ascites / pleural effusion (37.6%). The incidence of sarcopenia was significantly higher in those with nutritional risk than in those without nutritional risk (

To examine the feasibility of low-charge electrotherapy (LCE) in treating geriatric major depressive disorder (MDD) patients. Bi-temporal LCEs (approximately 25 mC) were performed with an electroconvulsive therapy (ECT) instrument three times per week. We used the Hamilton Depression Scale 17 (HAMD-17) and the Hamilton Anxiety Scale (HAMA) to assess the effects of LCE and the Mini-Mental State Examination (MMSE) to evaluate the cognitive function change before and after LCE. Six visits occurred at the baseline, after LCE sessions 3, 6, and 9, after the last session, and at the end of the one-month follow-up period. Four patients were enrolled in the study. Two patients completed all LCE sessions. Two patients withdrew during the trial, one due to the adverse event of uroschesis potentially caused by atropine and the other due to her own will. All four patients completed the follow-up sessions. The HAMD-17 and HAMA scores were reduced significantly at the last LCE session and the end of the follow-up period compared with the scores at the baseline. As measured by the MMSE, cognitive impairment showed no significant changes at the last LCE session and the end of the follow-up period compared with that at the baseline. In this case series, LCE showed potential as an alternative current-based treatment for treating geriatric MDD patients. Further research is needed to assess the efficiency and safety of LCE.

OBJECTIVE:
To explore the anti-nociceptive effect of patchouli alcohol (PA), the essential oil isolated from Pogostemon cablin (Blanco) Bent, and determine the mechanism in molecular levels.
METHODS:
The acetic acid-induced writhing test and formalin-induced plantar injection test in mice were employed to confirm the effect in vivo. Intracellular calcium ion was imaged to verify PA on mu-opioid receptor (MOR). Cyclooxygenase 2 (COX2) and MOR of mouse brain were expressed for determination of PA's target. Cellular experiments were carried out to find out COX2 and MOR expression induced by PA.
RESULTS:
PA significantly reduced latency period of visceral pain and writhing induced by acetic acid saline solution (P<0.01) and allodynia after intra-plantar formalin (P<0.01) in mice. PA also up-regulated COX2 mRNA and protein (P<0.05) with a down-regulation of MOR (P<0.05) both in in vivo and in vitro experiments, which devote to the analgesic effect of PA. A decrease in the intracellular calcium level (P<0.05) induced by PA may play an important role in its anti-nociceptive effect. PA showed the characters of enhancing the MOR expression and reducing the intracellular calcium ion similar to opioid effect.
CONCLUSIONS
Both COX2 and MOR are involved in the mechanism of PA's anti-nociceptive effect, and the up-regulation of the receptor expression and the inhibition of intracellular calcium are a new perspective to PA's effect on MOR.

OBJECTIVE:
We aimed to explore how fermented barley extracts with Lactobacillus plantarum dy-1 (LFBE) affected the browning in adipocytes and obese rats.
METHODS:
In vitro, 3T3-L1 cells were induced by LFBE, raw barley extraction (RBE) and polyphenol compounds (PC) from LFBE to evaluate the adipocyte differentiation. In vivo, obese SD rats induced by high fat diet (HFD) were randomly divided into three groups treated with oral gavage: (a) normal control diet with distilled water, (b) HFD with distilled water, (c) HFD with 800 mg LFBE/kg body weight (bw).
RESULTS:
In vitro, LFBE and the PC in the extraction significantly inhibited adipogenesis and potentiated browning of 3T3-L1 preadipocytes, rather than RBE. In vivo, we observed remarkable decreases in the body weight, serum lipid levels, white adipose tissue (WAT) weights and cell sizes of brown adipose tissues (BAT) in the LFBE group after 10 weeks. LFBE group could gain more mass of interscapular BAT (IBAT) and promote the dehydrogenase activity in the mitochondria. And LFBE may potentiate process of the IBAT thermogenesis and epididymis adipose tissue (EAT) browning via activating the uncoupling protein 1 (UCP1)-dependent mechanism to suppress the obesity.
CONCLUSION
These results demonstrated that LFBE decreased obesity partly by increasing the BAT mass and the energy expenditure by activating BAT thermogenesis and WAT browning in a UCP1-dependent mechanism.

OBJECTIVE:
Previous studies have indicated that the plasticizer di (2-ethylhexyl) phthalate (DEHP) affects lipid accumulation; however, its underlying mechanism remains unclear. We aim to clarify the effect of DEHP on lipid metabolism and the role of TYK2/STAT1 and autophagy.
METHODS:
In total, 160 Wistar rats were exposed to DEHP [0, 5, 50, 500 mg/(kg•d)] for 8 weeks. Lipid levels, as well as mRNA and protein levels of TYK2, STAT1, PPARγ, AOX, FAS, LPL, and LC3 were detected.
RESULTS:
The results indicate that DEHP exposure may lead to increased weight gain and altered serum lipids. We observed that DEHP exposure affected liver parenchyma and increased the volume or number of fat cells. In adipose tissue, decreased TYK2 and STAT1 promoted the expression of PPARγ and FAS. The mRNA and protein expression of LC3 in 50 and 500 mg/(kg•d) groups was increased significantly. In the liver, TYK2 and STAT1 increased compensatorily; however, the expression of FAS and AOX increased, while LPL expression decreased. Joint exposure to both a high-fat diet and DEHP led to complete disorder of lipid metabolism.
CONCLUSION
It is suggested that DEHP induces lipid metabolism disorder by regulating TYK2/STAT1. Autophagy may play a potential role in this process as well. High-fat diet, in combination with DEHP exposure, may jointly have an effect on lipid metabolism disorder.

OBJECTIVE:
To evaluate the synergy of the Burkholderia signaling molecule cis-2-dodecenoic acid (BDSF) and fluconazole (FLU) or itraconazole (ITRA) against two azole-resistant C. albicans clinical isolates in vitro and in vivo.
METHODS:
Minimum inhibitory concentrations (MICs) of antibiotics against two azole-resistant C. albicans were measured by the checkerboard technique, E-test, and time-kill assay. In vivo antifungal synergy testing was performed on mice. Analysis of the relative gene expression levels of the strains was conducted by quantitative reverse-transcription polymerase chain reaction (qRT-PCR).
RESULTS:
BDSF showed highly synergistic effects in combination with FLU or ITRA with a fractional inhibitory concentration index of ⪕ 0.08. BDSF was not cytotoxic to normal human foreskin fibroblast cells at concentrations of up to 300 μg/mL. The qRT-PCR results showed that the combination of BDSF and FLU/ITRA significantly inhibits the expression of the efflux pump genes CDR1 and MDR1 via suppression of the transcription factors TAC1 and MRR1, respectively, when compared with FLU or ITRA alone. No dramatic difference in the mRNA expression levels of ERG1, ERG11, and UPC2 was found, which indicates that the drug combinations do not significantly interfere with UPC2-mediated ergosterol levels. In vivo experiments revealed that combination therapy can be an effective therapeutic approach to treat candidiasis.
CONCLUSION
The synergistic effects of BDSF and azoles may be useful as an alternative approach to control azole-resistant Candida infections.

OBJECTIVE:
To compare the effects of electroacupuncture (EA) at "Zusanli" (ST 36) versus "Yanglingquan" (GB 34) in the pregnant rats on perinatal nicotineexposureinduced lung function and morphology of newborn rats and explore the rule of acupoint effect in EA for the prevention from lung dysplasia in newborn rats.
METHODS:
A total of 24 female SD rats were randomized into a normal saline group (S group), a nicotine group (N group), a nicotineST 36 group (N + ST 36 group) and a nicotineGB 34 group (N+GB 34 group), 6 rats in each one. Starting at the 6th day of pregnancy, 0.9% sodium chloride solution was injected subcutaneously in the S group, 1 mg/kg; and in the rest 3 groups, nicotine of the same dose was injected through to the 21st postnatal day to establish the perinatal nicotineexposure model. Simultaneously, during model preparation, EA was applied at "Zusanli" (ST 36) and "Yanglingquan" (GB 34) in the N+ST 36 group and the N+GB 34 group respectively, once a day, through to the 21st postnatal day. The lung function analytic system for small animal was adopted to observe the changes in lung function indicators in newborn rats, such as peak inspiratory flow (PIF), peak expiratory flow (PEF), expiratory resistance (RE), inspiratory resistance (RI) and dynamic compliance (Cdyn). HE staining was used to observe the morphological changes of lung, such as alveolar fusion and rupture.
RESULTS:
Compared with the S group, PEF and Cdyn were lower and PIF, RI and RE higher in the N group (all <0.01), additionally, alveoli were fused and ruptured, alveolar wall thickened, the numbers of alveoli reduced, the interspace of alveoli enlarged and the diameter increased (<0.01). Compared with the N group, in the N+ST 36 group, PEF and Cdyn were increased, PIF, RI and RE reduced (<0.05, <0.01), the alveolar fusion and rupture relieved, the numbers of alveoli increased, alveolar wall thinner, the interpsace of alveoli became normal and the diameter was reduced significantly (<0.01). In the N+GB 34 group, the changes of lung function and morphological indicators were not significant (>0.05).
CONCLUSION
Electroacupuncture at "Zusanli" (ST 36) in the pregnant rats significantly improves the perinatal nicotineexposureinduced lung function and morphology of newborn rats than electroacupuncture at "Yanglingquan" (GB 34).
