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 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 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 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 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.

Objective To compare the efficacy of continuous ambulatory peritoneal dialysis (CAPD) and hemodialysis (HD) on polycystic kidney disease (PKD) patients with end-stage renal disease (ESRD). Methods Retrospective analysis was made on 29 patients with PKD who carded out dialysis therapy for over 3 months in our department from January 2001 to December 2007. They were divided into the CAPD group (10 cases, 34.5%) and HD group (19 cases, 65.5%). Ten cases of non-PKD CAPD patients were randomly selected as the control, who matched the CAPD group in terms of age and gender. The patient information was recorded, such as general data, initial dialysis data, comphcations, survival time, quit of dialysis or death, etc. Kaplan-Meier method and Log-rank test were adopted to analyze the survival rate. Results The survival rates of 1-, 3- and 5-year for the CAPD group were 90%, 75% and 25% respectively, while for the HD group were 94.4%, 67.6%, and 48.3%, and for the control were 83.3%, 44.4% and 22.2% respectively, with no significant differences among 3 groups (P>0.05). group and the control were quite similar. The incidence of peritonitis for the CAPD group (0.62 times/patient year) was similar to that for the control (0.30 times/patient year)(P>0.05). The duration of the lust peritonitis[(23.5±4.0) months vs (20.0±15.8) months] and the catheter exit-site infection (0 time vs 1 time) for two groups were similar as well (P>0.05). One patient had hernia in CAPD group and no patient in control group had hernia. The incidence of peritoneal dialysate leakage was similar between these two groups. In the HD group, two patients (10.5%) had cerebral hemorrhage resulting in death, and 10 patients (52.6%) had cystic hemorrhage, 5 out of whom underwent operation due to repeated cystic hemorrhage and 2 cases received unilateral nephrectomy because of severe hemorrhage. No patient in CAPD group had cerebral hemorrhage but 1 patient (10%) had cystic hemorrhage and recovered after conservative treatment. The hemorrhage complication incidence of CAPD group was significantly lower than that of HD group (P<0.05). Conclusions The prognosis and complication incidence in PKD and non-PKD patients treated with CAPD are similar. The prognosis of PKD patients treated with CAPD or HD is also similar, and the risk of hemorrhage complications of PKD patients treated with CAPD may be decreased compared with those treated with HD. PKD patients can choose HD or PD as the initial therapy of ESRD unless existence of hernia or intolerance. PKD is not the contraindication of PD.

Objective To evaluate the hearing effects in hearing impaired children using FM system .Methods The FM listening evaluation for children questionnaire was used to evaluate 27 cases with sensorineural hearing loss who were fitted hearing aids or cochlear implants ,or using FM system .The auditory skills of the patients were evaluated in four kinds of listening environments :quiet ,noise ,auditory only and distance by this questionnaire .
