ABSTRACT
Objective: To investigate the mechanism of moxibustion in the treatment of diarrhea-predominant irritable bowel syndrome (IBS-D), by observing the effects of moxibustion at Tianshu (ST25) and Shangjuxu (ST37) on microRNA-133b (miRNA-133b), pituitary homeobox family factor 3 (Pitx3)/tyrosine hydroxylase (TH), and neurotransmitters in the brain tissue of IBS-D rats. Methods: Healthy Sprague-Dawley rats were randomly divided into a normal group, a model group, a moxibustion group, and a Western medicine group, with 12 rats in each group. Except for the normal group, the IBS-D rat model was established by mother-offspring separation and acetic acid enema combined with restraint stress stimulation in all the other groups. No intervention was performed in the normal and model groups. Mild moxibustion was applied to both Tianshu (ST25) and Shangjuxu (ST37) in the moxibustion group. Rifaximin was given by gavage in the Western medicine group. The physical status of rats in each group was observed at different periods. After the intervention, hematoxylin- eosin staining was performed to observe the histopathological morphology of rat colon; enzyme-linked immunosorbent assay was used to measure the levels of dopamine (DA), noradrenaline (NE), and 5-hydroxytryptamine (5-HT) in plasma, colon, and midbrain tissue of rats; the relative expression levels of miRNA-133b, Pitx3 mRNA, and TH mRNA in the midbrain tissue were measured by real-time fluorescence quantitative polymerase chain reaction, and the relative expression levels of Pitx3 and TH proteins in the midbrain tissue were measured by Western blotting and immunofluorescence. Results: The body weights of rats among groups and at different time points were statistically different (P<0.01). The body weight of the normal group was higher than that of the other groups over time (P<0.01). After modeling, the minimum volume threshold of abdominal withdrawal reflex (AWR) was significantly lower (P<0.01) and the loose stool rate was significantly higher (P<0.01) in the model, moxibustion, and Western medicine groups compared with the normal group; the miRNA-133b expression in the midbrain tissue was significantly lower (P<0.01), the expression levels of Pitx3 and TH in the midbrain tissue were significantly higher (P<0.01), and the levels of DA, NE, and 5-HT in plasma, colon and midbrain tissue were significantly higher (P<0.01). After the intervention, the minimum volume threshold of AWR was significantly higher (P<0.01), the loose stool rate was significantly lower (P<0.01), the miRNA-133b expression was significantly increased (P<0.01 or P<0.05) and the expression levels of Pitx3 and TH were significantly decreased (P<0.01) in the midbrain tissue, the levels of DA, NE, and 5-HT in plasma, colon, and midbrain tissue were significantly reduced (P<0.01) in the moxibustion and Western medicine groups compared with the model group; the levels of 5-HT in the colon and midbrain tissue of the moxibustion group were significantly lower than those in the Western medicine group (P<0.05), and there was no statistical difference compared with the remaining groups (P>0.05). Linear correlation analysis showed that miRNA-133b was negatively correlated with Pitx3 (r<0, P<0.01); Pitx3 with TH, TH with DA, and NE with 5-HT were positively correlated (r>0, P<0.01).Conclusion: Moxibustion at Tianshu (ST25) and Shangjuxu (ST37) improves diarrhea symptoms and visceral hypersensitivity in IBS-D rats. The mechanism may be related to up-regulating miRNA-133b, inhibiting Pitx3/TH, and reducing neurotransmitter expression levels in the midbrain tissue.

ABSTRACT
To evaluate several tests of physical performance for sarcopenia screening and assessment, by investigating physical performance and function in older women. 106 community-dwelling older women from a community in Shanghai were enrolled in this study. Physical function assessed by short physical performance battery (SPPB), timed get-up-and-go (TUG), handgrip strength, and usual gait speed were asked to perform. Total lean mass was determined by Dual energy X-ray absorptiometry, the relative appendicular skeletal muscle mass ( RASM) was defined as appendicular skeletal muscle mass/height2 . 13 individuals were diagnosed as sarcopenia according to a consensus diagnostic criteria for sarcopenia, as developed by the Asian Working Group for Sarcopenia ( AWGS) in 2014. Body mass index and handgrip strength in the sarcopenia group were significantly lower than those in the non-sarcopenia group (P=0. 026, P=0. 004 respectively), and there was no significant differences in the age, SPPB score, TUG, and usual gait speed. Linear regression analysis showed RASM was significantly positively correlated with body mass index (r=0. 842, P<0. 01), time to rise from a chair and return to the seated position five times (r=0. 203, P=0. 036),TUG(r=0. 258, P=0. 008)and grip strength (r=0. 217, P=0. 025), meanwhile, both body mass index and grip strength entered Logistic regression analysis. Low weight and low handgrip strength are independent predictive factors of sarcopenia in older women. Sarcopenia screening for older women with low body-weight and weak handgrip strength is more urgently required
ABSTRACT
Objective To explore the relationship between ERG4 gene overexpression and azole resistance in clinical Candida albicans strains. Methods The National Committee for Clinical Laboratory Standards (NCCLS)M27-A2 broth microdilution method was conducted to evaluate antifungal susceptibility of 34 clinical Candida albicans isolates in vitro. Total RNA was extracted from these Candida albicans strains and transcribed into cDNA. Real-time fluorescence-based quantitative PCR was performed to determine the mRNA expression of ERG4 gene. Statistical analysis was carried out by a two-sample t-test. Results The expression level of ERG4 mRNA was significantly higher in fluconazole-resistant than in -sensitive Candida albicans strains (4.20 ± 2.56 vs. 1.72 ± 1.33, t = 3.99, P < 0.05), higher in itraconazole-resistant than in -sensitive Candida albicans strains (3.60 ± 2.47 vs. 1.66 ± 1.61, t = 3.71, P < 0.05), and higher in voriconazole-resistant than in -sensitive Candida albicans strains (3.99 ± 2.72 vs. 2.07 ± 1.58, t = 2.91, P <0.05). Further more, increased ERG4 mRNA expression was also observed in isolates cross-resistant to all the three azole antifungal agents compared with those susceptible to all of them (4.49 ± 2.73 vs. 1.69 ± 1.82, t = 3.81, P < 0.05). Conclusions The overexpression of ERG4 gene may be associated with cross resistance to fluconazole, itraconazole and voriconazole in clinical Candida albicans strains, but its exact role is expected to be investigated through downregulation of the ERG4 gene.
