Objective To compare the clinical efficacy of intralesional betamethasone versus triamcinolone acetonide acetate in the treatment of active alopecia areata. Methods A total of 160 patients with active alopecia areata were divided into two groups, test group (n = 100) treated with intralesional betamethasone, and control group (n = 60) treated with intralesional triamcinolone acetonide. Both injections were given once every 3 weeks for 12 consecutive weeks. Results After 12-week treatment, the cure rate, response rate, and total response rate were 60.0%, 32.0% and 92.0% in the test group, respectively, compared to 41.7%, 31.67% and 73.3% in the control group, respectively. A significant increase was observed in the cure rate and response rate in the test group compared with the control group (χ2 = 10.25, 5.06, P < 0.01 and 0.05). During the treatment course, 8 (8%) patients in the test group and 9 (15%) patients in the control group developed localized atrophy of the scalp; 8 (8%) patients in the test group and 3 (5%) patients in the control group developed localized folliculitis; no significant difference was observed between the two groups in the occurrence of adverse reactions (P> 0.05). Conclusion Intralesional use of compound betamethasone injection has a notable therapeutic effect on alopecia areata.

Objective To detect the change of brain activity under different depth of anesthesia (DOA)noninvasively. Methods The Lempel-Ziv complexity C(n) was used to analyze EEG and its four components (delta,theta, alpha, beta), which was recorded from SD rats under different DOA. The relationship between C(n) and DOA was studied. Results The C(n) of EEG will decrease while the depth of anesthesia increasing and vice versa. It can be used to detect the change of DOA sensitively. Compared with power spectrum, the change of C(n) is opposite to that of power spectru,. Only the C(n) of delta rhythm has obvious variations induced by the change of DOA, and the variations of delta is as similar as the EEG's. Conclusion The study shows that the desynchronized EEG is replaced by the synchronized EEG when rat goes into anesthesia state from awake, that is just the reason why complexity and power spectrum appear corresponding changes under different DOA. C(n) of delta rhythm dynamic change leads to the change of EEG, and the delta rhythm is the dominant rhythm during anesthesia for rats.

This study is to investigate the protection effect of schisandrin B (Sch B) against oxidation stress of HK-2 cells induced by cisplatin and the mechanisms involved. HK-2 cells were cultured and divided into different groups: solvent control group, cisplatin exposure group, positive group, Sch B treatment group. Cell viability and toxicity were evaluated by MTT and LDH assay. GSH level and SOD enzymes activities were also measured. DCFH-DA as fluorescence probe was used to detect ROS level by fluorescence microplate reader. Nrf2 translocation was detected by Western blotting. Real time Q-PCR was used to detect expressions of NQO1, HO-1 and GCLC mRNA level. The results showed that Sch B could significantly inhibit the decline of cell viability induced by cisplatin treatment (P < 0.05) and the protective effect was in a dose dependent manner. Furthermore, Sch B treatment significantly inhibited the increase of ROS level induced by cisplatin and reversed the decrease of GSH level (P < 0.05). When Sch B concentration was up to 5 micromol x L(-1), SOD enzyme activities were also enhanced significantly compared with that of the cisplatin group (P < 0.05). It was shown that Sch B could cause nuclear accumulation of Nrf2 in association with downstream activation of Nrf2 mediated oxidative response genes such as GCLC, NQO1 and HO-1. These results suggested Sch B could protect against the oxidative damage of HK-2 cells induced by cisplatin via the activation of Nrf2/ARE signal pathway.

In our previous work, we found that trivalent dimethylarsinous acid (DMA(III)) have high affinity binding to cysteine residue 13 of rat hemoglobin. However, it is still unknown why arsenic intermediate metabolite DMA(III) has high binding affinity for Cysl3 but not for other cysteine residues 93, 140, 111 and 125. In order to better understand the molecular mechanism of DMA(III) with rat hemoglobin, we have done current study. So, SD rats were divided into control and arsenic-treated groups randomly. Arsenic species in lysate of red blood cells were analyzed by HPLC-ICP-MS, and then determined by a hybrid quadrupole TOF MS. In addition, trivalent DMA(III) binds to different cysteine residues in rat hemoglobin alpha and beta chains were also simulated by Molecular Docking. Only Cys13 in alpha chain is able to bind to DMA(III) from the experiment results. Cys13 of alpha chain in rat hemoglobin is a specific binding site for DMA(III), and we found that amino acids compose pockets structure and surround Cys13 (but not other cysteine residues), make DMA(III) much easy to bind cysteine 13. Taken together, the DMA(III) specific binding to Cys13 is related to spatial structure of Cys13.

The protein product of metastasis-associated in colon cancer 1 (MACC1) gene induces the activation of hepatocyte growth factor/mesenchymal-epithelial transition factor (HGF/c-Met) signaling pathway through transcriptionally activating c-Met gene and upregulating its expression to further promote tumor invasion and metastasis.High level expression of MACC1 is associated with the occurrence and metastasis of a wide variety of human tumors, such as colon cancer, gastric cancer, liver cancer, lung cancer, ovarian cancer etc.In addition, the overexpression of MACC1 is also closely associated with clinical TNM stages and distant metastasis.Thus, MACC1 can serve as an independent indicator of tumor metastasis and prognosis, and become a new target for gene therapy.
