Psoriasis is a chronic, recurrent, and inflammatory skin disease induced by multiple factors. Its typical clinical manifestation is scaly erythema or plaques, which can cause various complications such as metabolic syndrome, cardiovascular disease, and inflammatory arthritis, seriously affecting the quality of life of patients. A deep understanding of the pathogenesis of psoriasis is helpful to discover new therapeutic targets and develop effective new therapeutic drugs, thus having important clinical significance. This manuscript reviews the new advances in the pathogenesis and drug research of psoriasis in recent years.

Objective To study the effects of the compound xueshuantong capsule ( FXC) against cerebral ischemia and hypoxia in mice. Methods KM mice were randomly divided into the sham operation group ( normal control group) , model control group, positive control group and FXC at high-,medium-and low-dose(0. 75,1. 50,and 2. 25 g·kg-1 ) groups. After intragastric administration for 7consecutive days,cerebral ischemia model was established by unilateral carotid arteries ligation. The cerebral water content and stroke index were recorded. The viability of the mice was determined by testing atmospheric hypoxia,sodium nitrite poisoning and acute cerebral anoxia. Results FXC decreased water content and stroke index of the mice suffered from unilateral carotid artery ligation dose-dependently (P<0. 05,P<0. 01) . It also prolonged the survival of mice by tolerating absence of oxygen,sodium nitrite poisoning and acute cerebral anoxia (P<0. 05,P<0. 01). Conclusion FXC has a protective effect on cerebral ischemia and hypoxia in mice.

Objective To investigate the ch an ges of gastric intramucosal pH (pHi) during orthotopic liver transplantation (OL T) without venovenous bypasss. Methods Twenty patients (14 males and 6 females) aged (46.7 ?4.6) years, undergoing orthotopic liver transplantation without venovenous byp asss, were included in this study. A gastric tube technique was used to draw gas tric juice 3～5 mL to determine pHi and PiCO 2 before OLT, at 20 min preanhep atic phase, 30 min anhepatic phase, 30 min new hepatic phase and at 2 h and 2 4 h after operation. The arterial blood samples collected taken for the measure ments of PaCO 2, PO 2, pH, BE and HCO 3- at the same time point s as above. pHi was calculated through Henderson-Hasselbach equation. Results The gastric intraumucosal pH (pHi) was decreased significant ly at the time points of 30 min anhepatic phase and 30 min new hepatic phase c ompared with before operation (P

Objective:To identify metastasis-associated genes in salivary gland adenoid cystic carcinoma(ACC).Methods:Salivary gland adenoid cytic carcinoma cell line ACC-2 and its highly metastatic ACC-M cells were used to screen the metastasis-related genes in ACC by microarray technology.Two fluorescent cDNA probes labeled with Cy3 and Cy5 dyes,were prepared from the mRNA samples of ACC-2 and ACC-M cells by reverse transcription method.The two color probes were then mixed and hybridized on the cDNA chip constructed by double dots of 1152 human genes,and scanned at two wave lengths.Differentialy expressed genes of the two cell lines were analyzed using computer.Then seven of the differently expressed genes were further validated by RT-PCR technique.Results:Of the 1,152 known genes and expressed sequence tags,26 showed significantly different expression level(minimum 2 fold) between the two cell lines.Among the 26 genes,19 were up regulated(with ratio more than 2) and 7 were down(with ratio less than 1/2).The results of RT-PCR analysis for 7 differently expressed genes were coincident with those of microarray assay.Conclusions:Down regulation of LIFR,LCP1,DPEP1 and ABLIM1,and up regulation of DCC,MMP1 and CNTN2 may be related to the highly metastatic potential of ACC-M cell line.

Objective To investigate the effect of early warning face pattern of weight combined with health education in weight management of maintenance hemodialysis patients.Methods Toally 223 maintenance hemodialysis patients hospitalized in the hospital from July to December 2014 (17,617 cases of hemodialysis) were set as the control group and 223 maintenance hemodialysis patients from January to June 2015 (17,281 cases of hemodialysis) were set as the experiment group.The control group was given routine health education and the experiment group was given health education and early warning face pattern of weight.The two groups were compared in terms of the ratio between interdialytic weight gain (IDWG) and interdialytic dry weight ratio (IWGR) as well as the hemodialysis-related complications.Results The IDWG/IWGR ratio in the experiment group was significantly better than that of the control group (P＜0.05).The incidence of hemodialysis-related complications were significantly lower than that of control group.Conclusion Early warning face pattern of weight used in health education can effectively control the patient's interdialytic weight gain (IDWG) and reduce the hemodialysis-related complications.

Objective: To observe the clinical efficacy of combining two needling manipulations, Er Long Xi Zhu (two dragons playing with a pearl) and Guo Yan Re (heat produced to reach the eyes), in treating dry eye syndrome (DES) of lung-yin deficiency pattern. Methods: Fifty-six eligible DES patients of lung-yin deficiency were randomized into an observation group and a control group, with 28 cases in each group. Same acupoints were selected in the two groups: Cuanzhu (BL 2), Sizhukong (TE 23), Taiyang (EX-HN 5) and Fengchi (GB 20) were chosen as the major points and Feishu (BL 13) and Chize (LU 5) as the adjuvant. Er Long Xi Zhu and Guo Yan Re needling manipulations were applied in the observation group while twirling reinforcing manipulation was used in the control group. Treatment was conducted once per day in both groups, for two sets of 15 consecutive days at a 2-day interval. Changes in the symptom score, tear break-up time (BUT) and tear production were observed afterwards, and the clinical efficacy was also compared between the two groups. Results: The total effective rate was 92.8％ in the observation group, higher than 71.4％ in the control group, and the between-group difference was statistically significant (P<0.05). After treatment, the symptom score, tear BUT and tear production showed significant improvements in both groups (all P<0.05); the symptom score, BUT and tear production in the observation group were significantly different from those in the control group (all P<0.05). Conclusion: Given the same acupoint selection, combining Er Long Xi Zhu and Guo Yan Re needling manipulations can produce more significant clinical efficacy than twirling reinforcing manipulation in treating DES of lung-yin deficiency pattern.

A method for qualitative analysis of constituents in Panax notoginseng by UPLC-LTQ-Orbitrap mass spectrometry was established. Based on the high-resolution mass information, MS/MS fragmentation behaviors and chemical components from literatures, 43 compounds were identified or tentatively characterized. New type saponin aglycone, combined with malonyl-substituted and acetyl-substituted saponins were discovered and plausibly identified in this study. This work could be helpful for the quality control and further phytochemical studies of Panax notoginseng, and provided a good example for the analysis of chemical constituents in traditional Chinese medicine.

Objective To investigate the effects of single dose of dexmedetomidine and fentynyl on treatment of emergence agitation in adult patients after general anesthesia.Methods Sixty patients suffering from emergence agitation after general anesthesia were divided into two groups randomly(n=30 each):dexmedetomidine group (group D)and fentaynl group (group F).Patients in group D received dexmedetomidine at a dose of 0.5μg/kg,and those in group F received fentanyl at a dose of 1μg/kg respectively.If patients still agitate after above treatment,intermission infusion of propofol at bolus of 1.0 mg/kg was used for further treatment till patients attain peaceful state.Results Twen-ty-nine paients in group D had no agitation,only one patient had mild agitation after administration of dexmedetomidine,while four patients had severe agitation,four patients had moderate agitation and 9 patients had mild agitation after administration of fentanyl(P<0.05);the time from first treatment to no agitation in group D was (11±3)min,shorter than that in group F (27±9)min (P<0.05);the dose of propofol used in group D was (50±0)mg,less than accumulative doses of propofol in group F (270±40)mg (P<0.05);21 (70%)patients in group D had radycardia and 9 (30%)patients in group F had respiratory depression(P<0.05).Conclusion Intravenous dexmedetomidine at a dose of 0.5 μg/kg attainted was effective in treating emergence agitation in adult patients after general anes-thesia as compared with fentanyl.
