Objective To evaluate the epidemiological and clinical characteristics of adult-measles.Methods The clinical data of 67 patients with adult-measles were retrospectively analyzed.Results In summary,67 pa- tients with measles were involved in this study,with 39 males and 28 females.The gender rate was 1.39:1 and the average age was about 32 years old.There were 39 peasants and 28 workers & officials of 67 patients.The peak of the incidence of disease emerged in April and June(40.3%),especially from November 2000 to October 2004 (67.2%),and the positive rate of measles virus IgM antibody in serum was 95.1%(39/41).There were 58 patients (86.6%)who had the fever beyond 39℃and 18 patients(26.9%)who had measles induced viral hepatitis.Con- clusions There is a trend that measles may be related to the nonstandard inoculation of measles vaccine of the de- crease of IgM antibody levels and so on.Meanwhile,serious toxemic symptoms and liver damage can be clinically ob- served.

Objective:To examine the relationships between acute stress disorder (ASD) symptoms,posttraumatic stress disorder (PTSD) symptoms and depressive symptoms in children survivors following the Lushan earthquake in China.Methods:One hundred ninety-seven children aged 1 to 14years (93 male and 104 female) were followed up at two and six weeks after Lushan earthquake.The ASDS,UCLA PTSD Reaction Index and DASS were used to measure the ASD,PTSD and depressive symptoms.Results:The average scores of ASDS and the depression subscale of DASS at two weeks after earthquake were(36.5 ± 10.9) and (3.3 ± 2.8),respectively.The average scores of UCLA PTSD Reaction Index and the depression subscale of DASS-21 at six weeks after earthquake were (18.5 ± 12.6) and (3.3 ± 3.5),respectively.The rates of ASD and PTSD were 28.6％ and 8.2％,respectively.The cross-lagged structural equation analysis with latent variables indicated that the ASD symptoms at two weeks after earthquake positively predicted PTSD symptoms (β =0.59,p ＜ 0.001) and depressive symptoms (β =0.29,p ＜0.001) at six weeks after earthquake.But there was no significant association between depressive symptoms at two weeks and PTSD symptoms at six weeks after earthquake.Conclusion:ASD symptoms in the early time postearthquake could predict subsequent PTSD and depressive symptoms,while depressive symptoms tend to remain stable within six weeks after earthquake.

OBJECTIVETo analyze the efficacy and medication principles of Professor Xu Fu-songs traditional Chinese medicine (TCM) protocols for male diseases.

METHODSWe reviewed and descriptively analyzed the unpublished complete medical records of 100 male cases treated by Professor Xu Fu-song with his TCM protocols from 1978 to 1992.

RESULTSThe 100 cases involved 32 male diseases, most of which were difficult and complicated cases. The drug compliance was 95%. Each prescription was made up of 14 traditional Chinese drugs on average. The cure rate was 32% , and the effective rate was 85%. Professor Xu Fu-song advanced and proved some new theories and therapeutic methods.

CONCLUSIONProfessor Xu Fu-song's TCM protocols can be applied to a wide range of male diseases, mostly complicated, and are characterized by accurate differentiation of symptoms and signs, high drug compliance, and excellent therapeutic efficacy.

Objective To design an experiment for method-comparison and bias estimation of multi tests on multi instruments.Methods According to the procedure described by the NCCLS approved guideline EP9-A and improving the method of sample collection,we took 8 patient mixing samples each day to analyze all comparison tests on 11 auto-chemistry analyzer within following 5 days.The duplicates were assessed within the same run.The coefficient of correlation and average bias% were calculated,and the system errors at medical decided levels were assessed.Results Taking ALT as an example,the coefficients of correlation were between 0.994-1.000,and the average bias% were between-0.460%-4.927%,SE at 40U/L was-1.510-1.834 and SE at 300 U/L was-3.101-9.188.Conclusion In all tests that joined the comparison among the different instruments,28 tests were acceptable,2 tests were acceptable after modifying the coefficients,and AMY and LIP were not acceptable.

Objective To investigate the possible signaling mechanisms by which recombinant human platelet-derived growth factor (rhPDGF) accelerated healing of cutaneous wound in diabetic rats. Methods Four full-thickness skin wounds were incised in the back of 26 male Wistar diabetic rats. The wounded rats were divided into 3 groups (7 or 8 rats each group). One group without treatment was used as a control, and the other 2 groups were treated with rhPDGF at a dose of 7.0 μg/cm2 wound or vehicle ( DMSO/0.9%NaCl, vol/vol 1:1) from 1 to 14 days. The wound healing was evaluated by the measurements of the wound volume and area. Immunofluorescent and immunohistochemical staining were used to examine the phosphorylation of extracellular signal-regulated kinase 1/2(ERK1/2) and the expression of proliferative cell nuclear antigen (PCNA), respectively. Results Granulation tissue appeared in the bed of wound after injury. The number of blood capillary buds and fibroblasts was greater in the rhPDGF-treated group than that in the other 2 groups. A lot of inflammatory cells infiltration and collagen deposition were observed in the wound. The wound-volume in the rhPDGF-treated group was smaller than that in control group ( P ＜ 0.05). The reepithelialization rate in rhPDGF-treated group was higher than that in the other 2 groups at 7 days after injury ( P ＜ 0.05). The expression of PCNA in reparative cells was higher in rhPDGF-treated group than in control group or vehicle-treated group at 3,7 days after injury( P ＜ 0.05). The phosphorylation of ERK1/2 was stronger in rhPDGF-treated group than that in control group or vehicle group at 7 and 14 days after injury( P ＜ 0.05). Conclusion These results suggest that rhPDGF accelerates wound healing and improves healing quality by increasing the phosphorylation of ERK1/2.

Objective To determine the effects of hypoxia inducible factor-1α(HIF-1α) expression on postoperative adjuvant radiotherapy in esophageal carcinoma. Methods 95 cases with esophageal carcinoms who received radical operation were analyzed with followed-up data from 1995 to 1998.Expression of HIF-1α in 45 patients with esophageal carcinoma who received radiotherapy after radical operation were deternlined by immunohistochemical method in contrast with 50 patients with esophageal carcinoma received surgery alone.Kaplan-Meier method and COX proportional hazard model were used to analyze.Results The positive expression of HIF-1α in esophageal carcinoma was observed mainly in the nucleus of tumor cells.The positive expression rate of HIF-1α in esophageal carcinoma was 58.9%.The expression of HIF-1α had no relationship with age,sex,histologic subtype and T stage,but had positive relationship with recurrence and distant metastasis.There was significant difference between patients with positive and negative HIF-1α protein expression in surgery alone and postoperation radiotherapy group. COX model analysis showed that HIF-1α had separate and significant impacts on prognosis in surgery group and surgery plus radiotherapy group. Conclusion Over expression of HIF-1α protein suggests a poor prognosis,and has tendency to resist radiotherapy in esophageal carcinoma.

Objective To investigate the neuroprotective effect of escitalopram on focal cerebral ischemia/reperfusion in rats and its possible mechanisms.Methods Seventy-five male Sprague-Dawley rats were randomly divided into three groups:sham operation,saline control and escitalopram intervention groups (n =25 in each group).A focal cerebral ischemia reperfusion model in rats was induced by the intraluminal suture method.The modified neurological severity scale was used to evaluate neurological deficit in rats (n =5 in each group).Laser confocal technology was used to observe the microvascular diameter,density,and total area in ischemic region (n =5 in each group).Enzyme-linked immunosorbent assay was used to detect the plasma concentration of vascular endothelial growth factor (VEGF) (n =5 in each group).Immunohistochemical staining (n =5 in each group) and Western blotting (n =5 in each group) were used to detect the expression of VEGF in the ischemic brain tissue.Results At day 14 after modeling,the neurological deficit improved more significantly in the escitalopram intervention group than that in the saline control group (4.39 ±0.92 vs.6.57 ± 1.13; P =0.015).The 3D confocal vascular imaging showed that capillary diameter in the escitalopram intervention group was significantly smaller than that in the saline control group (2.93 ± 0.19 μm vs.3.56 ± 0.22 μm; P ＜0.01); the vascular density was significantly higher than that in the saline control group (232.68 ±12.54/0.002 mm3 vs.176.26 ± 10.87/0.002 mm3; P=0.000); the total microvascular area was significantly greater than that in the saline control group (89 154± 3 298 μm2/0.002 mm3 vs.75 368.14± 3 519 μm2/0.002 mm3; P=0.000).Enzyme-linked immunosorbent assay showed that the plasma VEGF concentration in the escitalopram intervention group was significantly higher than that in the saline control group (50.35 ± 5.44 pg/ml vs.13.75 ± 4.12 pg/ml; P =0.000).Immunohistochemical analysis showed that the VEGF expression in ischemic brain tissue in the escitalopram intervention group was significantly higher than that in the saline control group (P =0.000).Western blotting showed that the VEGF expression in ischemic brain tissue in the escitalopram intervention group was significantly higher than that in the saline control group (0.94 ±0.18 vs.0.62 ±0.22; P =0.006).Conclusions Escitalopram may reduce neurological deficit in cerebral ischemia/reperfusion in rats.Its mechanisms may be associated with VEGF-mediated angiogenesis.
