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.

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.

Objective To investigate the quality of life(QOL)of patients with stroke and its related factors.Methods The QOL of eighty-two stroke survivors was assessed in terms of SF-36 scores,motor impairment (Fugl-Meyer),disability[Barthel index(BI)]and depression(HAMD)more than one year after their first episode.Their social demographic characteristics such as age,gender,education and income were recorded,as were the characteristics of their disease and any complications.Multiple regression analysis was used to analyse the related factors.Results The average age of the 82 subjects was 61.89 + 9.81 years(range,33-81).56 of them were male (68.2％).Scores on all items of the SF-36 for these subjects were lower than those of a normal population.Correlation analysis showed income,cost for medical care,regular exercise,movement function,ability in the activities of daily living,depression,hypertension and shoulder pain were significantly correlated with most of the SF-36 domain scores.Motor function,income and cost for medical care explained 34％ of the variance in SF-36 scores.Motor function was the single most important factor.Conclusion The major factors affecting the QOL of stroke patients are motor function,level of income and cost for medical care.Paying more attention to rehabilitation treatment,taking regular exercise and more income could help improve the QOL of stroke survivors.

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.

Objective To evaluate the efficacy and tolerance of monochromatic excimer light (MEL) 308 nm in the treatment of vitiligo. Methods Seventy-seven patients were enrolled in the prospective and open clinical study. Two-hundred and one lesions were subjected to local phototherapy of MEL 308-nm once a week for 3 to 6 months. Results Of these lesions, 86.6% obtained repigmentation at different degrees. The repigmentation was more obvious in lesions on the head, face, neck and trunk than in those on the limbs or extremities. Moreover, patients with generalized and segmental vitiligo got a better improvement than patients with other types of vitiligo. Conclusion MEL 308-nm is effective in the treatment of vitiligo without obvious adverse effects.

Objective To compare the differences of lung pathological changes of acute lung injury in mice in-duced by lipopolysaccharide ( LPS) and graphite particles, and to explore the possible mechanisms of acute lung injury in-duced by fine particles of different origins.Methods 140 male specific-pathogen-free Kunming mice weighing 18-20 g were randomly divided into 7 experimental groups, in addition to the normal control group.The experimental groups were treated by intratracheal instillation of LPS solution or graphite powder suspension in different doses, respectively, to induce acute lung injury in the mice.The mortality of the mice was observed, and pathological changes of the lung tissues were ex-amined by light and transmission electron microscopy.Western blot was used to detect the protein expression of neutrophil elastase ( NE) in lung tissues , and real-time quantitative PCR was used to detect mRNA expression of monocyte chemotac-tic protein-1 ( MCP-1) in the lung tissue .Results Compared with the normal control group, some pathological changes were observed in the lung tissues of the groups L ( LPS) and G ( graphite) .There were numerous macrophages in the lung tissues in the group G mice, and exudate, mainly neutrophils, in the lung tissues of the group L.The NE protein expres-sion in the lung tissue was significantly higher than that of the normal control group ( P<0.05) , and there was also a sig-nificant difference between the groups L and G (P<0.05).The MCP-1 mRNA expression in lung tissues was higher in the control group (P<0.01), and there was also a significant difference between the groups L and G (P<0.01).Conclu-sions Diverse types of particulate matters induce different pathological changes in the lungs, therefore the mechanism may also be different in the inflammatory responses.It means that the lung injuries caused by fine particles of mixed composition may have complex mechanisms.

Aim To investigate the effect of Jinlida on cholesterol-related genes in skeletal muscle in fat-in-duced insulin resistance ApoE-/ - mice. Methods Ten male C57 BL/6 J mice were selected as normal group ( NF );50 male ApoE-/ - mice with a high-fat feeding after 16 weeks ( HF) were divided into model group, rosiglitazone ( LGLT ) , Jinlida low dose group ( JLDL, 0. 95 g · kg-1 · d-1 ) , Jinlida medium dose group ( JLDM, 1. 9 g·kg-1 ·d-1 ) , Jinlida high dose group (JLDH, 3. 8 g·kg-1·d-1), which were per-formed intragastric administration for 8 weeks. Oil red O staining of mouse skeletal muscle was used for fat ac-cumulation. Insulin receptor ( INSR) , insulin receptor body substrate-1 ( IRS-1 ) , low-density lipoprotein re-ceptor ( LDLR ) , cholesterol sensor ( SCAP ) mRNA and protein expression in mouse skeletal muscle were measured by quantitative reverse transcription PCR ( RT-PCR ) and Western blot. Results Compared with NF group, fasting blood glucose ( FBG) , choles-terol ( TC ) , triglyceride ( TG ) and low density lipo-protein cholesterol ( LDL-C ) of HF mice were signifi-cantly elevated, while high-density lipoprotein ( HDL-C ) significantly decreased ( P < 0. 05 ) . Compared with HF group, Jinlida group could reduce to varying degrees FBG, TC, TG and LDL-C in mice, and in-crease HDL-C ( P <0. 05 ) . Jinlida could downgrade fasting serum insulin ( FINS ) level, and improve the insulin sensitive index ( ISI ) ( P < 0. 05 ) . Jinlida could obviously improve skeletal muscle fat accumula-tion of mice. Compared with NF group, skeletal mus-cle INSR, IRS-1, LDLR mRNA and protein levels of HF group were significantly decreased ( P <0. 05 ) , while SCAP mRNA and protein level increased signifi-cantly (P<0. 05). Compared with HF group, Jinlida could increase to varying degrees INSR, IRS-1, LDLR mRNA and protein levels ( P < 0. 05 ) , and lower SCAP mRNA and protein levels ( P<0. 05 ) . Conclu-sion Jinlida can alleviate fat-induced insulin resist-ance in ApoE-/ - mice through regulation of cholester-ol-related gene expression.

AIM:Toinvestigatetheeffectsofcalcitoningene-relatedpeptide(CGRP)onmyocardinexpres-sion and phenotypic switch in vascular smooth muscle cells ( VSMCs) .METHODS:VSMCs were obtained by aortic tissue adherent culture and treated with angiotensin Ⅱ( AngⅡ) , AngⅡ+CGRP or AngⅡ+CGRP +CGRP8-37 .The protein expression of myocardin and the phenotypic proteins of the VSMCs was detected by Western blot .RESULTS:The expres-sion of myocardin in cultured VSMCs showed downregulation along with time expansion .The protein level of myocardin was higher at 48 h and 72 h than that at baseline in the cultured VSMCs (P<0.05).However, the myocardin was lower at 48 h and 72 h than that at baseline after treatment with CGRP in cultured VSMCs (P<0.05).Furthermore, at 48 h in cul-tured VSMCs, the myocardin decreased along with α-smooth muscle actin (α-SMA) (P<0.05), and osteopontin (OPN) increased (P<0.05) in AngⅡ group compared with control group .After treatment with CGRP, the levels of myocardin andα-SMA become higher ( P <0.05 ) but OPN was lower ( P <0.05 ) in CGRP group than those in AngⅡ group. CGRP8-37 abrogated CGRP-induced increase in myocardin and α-SMA and decrease in OPN in CGRP 8-37 group compared with CGRP group .CONCLUSION: CGRP may regulate the phenotypic switch of the VSMCs and maintain the cells in contractile phenotype through the upregulation of myocardin protein , which may be accomplished by the combination of CGRP and its receptor .
