OBJECTIVE: To verify the relationship between THI and VAS scores in patients with sudden hearing loss and tinnitus in a prospective study. METHOD: Forty-four patients classified their tinnitus according to VAS and THI before and after treatment, and both scores were compared through the Pearson's correlation coefficient test and Nonparametric tests. RESULT: There was a correlation between VAS and THI scores in patients with sudden hearing loss and tinnitus. Tinnitus assessment scores were significantly reduced after treatment. Decreasing of THI and VAS scores were not depended on frequency and loudness of tinnitus and severity of deafness, but therapeutic effect of sudden sensorineural hearing loss. CONCLUSION THI and VAS scores are useful for assessment of tinnitus in patients with sudden hearing loss and tinnitus.

Objective To observe the morphology of ethanol-wet dentin surfaces and detect their nano-scale adhesion force (Fad) by atomic force microscopy (AFM) in order to explore the potential mechanism of ethanol-wet bonding in improving clinical dentin bonding effectiveness.Methods Dentin slices from human premolar roots were prepared into flat ones, polished, and then randomly divided into five groups.All the specimens were acid-etched, rinsed, and left moist.They were then treated with 100％ ethanol for 0s (control group), 20s, 60s, 3×60s, or stepwise ethanol application.Afterwards, each group was scanned for the morphology in air and the Fad was probed by AFM.One-way ANOVA followed by Tukey`s test was employed for multiple comparisons using SPSS16.0.Results Compared with control group, ethanol-wet dentine produced a less undulating and relatively smooth surface topography.Ethanol-wet protocol significantly decreased the value of Fad in the experimental groups (P<0.001), in which 3×60s and stepwise ethanol application groups showed the lowest Fad.No difference was found between these two groups (P>0.05).Conclusion When using AFM in air, ethanol-wet protocol with longer time can produce a less undulating and relatively smooth surface topography and decrease the Fad, whichindicates that the water saturated in dentin matrix was replaced more thoroughly by longer ethanol application time.This will benefit hydrophobicity of the dentin bonding interface.

This study started from the effect of baicalin (BC), the main active component of the labiaceae plant Scutellaria baicalensis, on collagen-induced arthritis (CIA) in rats, to explore the mechanism of glucose metabolism reprogramming in fibroblast like synoviocytes (FLSs), a key effector cell of synovial inflammation in rheumatoid arthritis (RA). First of all, CIA rats and tumor necrosis factor-α (TNF-α)-induced RASFs in vitro and in vivo models were established, the arthritis index (AI) score and histopathological changes of CIA rats after BC administration were observed, and the levels of inflammatory factors in serum and cell supernatant were quantified by ELISA, immunocytochemistry and Western blot were used to detect the expression of G-protein-coupled receptor 81 (GPR81) and pyruvate dehydrogenase kinase 1 (PDK1) proteins. In addition, the kit was used to measure the levels of key products and enzyme activities in glucose metabolism reprogramming. The results showed that BC (50, 100 and 200 mg·kg^-1) could alleviate the symptoms of arthritis in CIA rats in a dose-dependent manner, inhibit synovial hyperplasia, alleviate the infiltration of inflammatory cells, down-regulate the levels of pro-inflammatory factors TNF-α and interleukin (IL)-1β, and up-regulate the levels of anti-inflammatory factor IL-10 in CIA rats. At the same time, the secretion levels of lactate, pyruvate, acetyl-CoA, citrate and the activity of lactate dehydrogenase B (LDH-B) were decreased, and the expressions of GRP81 and PDK1 were down-regulated, suggesting that BC mediated the reprogramming process of glucose metabolism. However, when GPR81 inhibitor 3-OBA inhibited lactate uptake, the activity of LDH-B was significantly increased, suggesting that BC inhibited the expression of PDK1, a key enzyme in the reprogramming metabolism from glycolysis to oxidative phosphorylation. All animal experiments in this study were conducted in accordance with the ethical standards of the Laboratory Animal Care Center of Anhui University of Chinese Medicine (approval number: AHUCM-rats-2021049). These studies revealed that baicalin mediated metabolic reprogramming of RASFs from glycolysis to oxidative phosphorylation by inhibiting PDK1 protein expression, and alleviated joint inflammation in CIA rats.

ObjectiveTo observe the effect of exercise on expression of protein kinase B (PKB) in adipose tissue of insulin resistant rats fed by high fat diet.Methods30 male Wistar rats were randomly divided into the control group (n=10),given basic diet; the model group (n=20), given fat diet. After 4 weeks, the model group was randomly divided into 2 subgroups, the insulin resistant group was continually given high fat diet, the exercise treated group accepted high fat food and swimming training. After 6 week intervention, the expression of PKB stimulated by insulin in adipose tissue was determined with Western blotting at the end of experiment.ResultsAfter long term high fat diet, expression of PKB in adipose tissue of the insulin resistant group decreased by 23.5% comparing with the control group (P<0.01). After 6 weeks swimming training, the expression of PKB of the exercise treated group was increased by 19.2% comparing with the insulin resistant group (P<0.01).ConclusionExercise treatment can significantly elevate the expression of PKB and ameliorate the state of insulin resistance.

AIMTo investigate the effect of 5-hydroxytryptamine (5-HT) on spontaneous unit discharges of primary somatosensory cortex (SI-SUD) and the role of 5-HT1A receptor in 5-HT inhibitory effect on SI-SUD in rat.

METHODSThe SI-SUD was recorded before and during microiontophoresis of 5-HT and 8-OH-DPAT (the selective agonist for 5-HT1A receptor. The changes of mean of interspike interval (MISI) of SI-SUD were analysed and handled with the statistics.

RESULTS(1) Effects of 5-HT on SI-SUD may be inhibitory (48/96), excitatory (26/96) or non-responsive (22/96), and the major effect is inhibitory. (2) In 20 of 5-HT inhibited units, 17 are also inhibited with microiontophoresis of 8-OH-DPAT, but 3 have no obvious response to 8-OH-DPAT.

CONCLUSIONThe major effect of 5-HT on SI-SUD is inhibitory. In majority of 5-HT inhibited units, 5-HT1A receptor may be existence, which may involve in the inhibition of 5-HT on SI-SUD.
