Objective To evaluate the clinical efficacy of thalidomide plus mometasone furoate cream under occlusion and ultraviolet irradiation for the treatment of prurigo nodularis.Methods A non-randomized,parallel,controlled study was carried out.Eighty patients with prurigo nodularis were divided into 3 groups,i.e.,control group(no irradiation),ultraviolet A1(UVA1)group,and ultraviolet B(UVB)group.All the patients were treated with oral thalidomide and topical mometasone furoate cream under occlusion.Additionally,the patients in UVA1 group and UVB group received UVA1 and NB-UVB irradiation,respectively,thrice a week for no less than 8 weeks.Patients were evaluated at the baseline,and on day 30 after the beginning of treatment.Clinical outcome parameters included disease severity score and visual analogue scales for pruritus.Peripheral blood eosinophils were counted during each visit.Rank sum test was performed to compare the clinical efficacy between the 3 groups,and the relationship between peripheral blood eosinophile count and visual analogue scales for pruritus was analyzed.Results After 30 days of treatment,skin lesions were markedly improved in 5 (21.74％),13(43.33％)and 9(37.5％)patients,and improved in 7(30.43％),12(40％)and 7(29.17％)patients,in the control group,UVA1 group and UVB group respectively;a marked response in pruritus was noted in 7(30.43％),18(60.00％)and 14(58.33％)patients respectively in the control group,UVA1 group and UVB group.The efficacy on skin lesions and pruritus was significantly stronger in the UVA1 group and UVB group than in the control group(skin lesions:Z =8.21,5.22,both P ＜ 0.01;pruritus:Z =4.50,4.50,both P ＜ 0.01),but similar between the UVA1 group and UVB group(skin lesions:Z =0.50,P ＞ 0.05;pruritus:Z =0.35,P ＞ 0.05).Peripheral blood eosinophil count was positively correlated with the visual analogue scale for pruritus in the patients(r =0.53,P ＜ 0.01).Conclusions Thalidomide combined with mometasone furoate cream under occlusion and ultraviolet irradiation shows notable efficacy for the treatment of prurigo nodularis,and the combination with UVA1 or NB-UVB irradiation enhances the efficacy of thalidomide and mometasone furoate cream under occlusion.

Objective To evaluate prognostic indicators in severe traumatic brain injury and intracania hamatomas with hernia and analyze which is the most important indicator.Methods Data of 84 cases with severe traumatic brain injury were retrospectively analyze .Age,GCS,pupil reflex,midline shift,compression of the cisteme,decompression time and complex injury were considered as possible prognostic indicators.SPSS13.0 was employed to analyze the data,Logistic regression(Forward conditional)analysis was done to confirm which are the most important prognostic indicators for severe traumatic brain injury and to evaluate the practical value in predicting prognosis(X2= 22.92,P＜ 0.01).Results 48 patients died and 36 survived.56(67%)patients had a bad prognosis(GCS≤3)and 28(33%)had a good prognosis(GCS ＞3).Those who had a shorter decompression time(≤3h)had a better prognosis than those who had a longer decompression time(＞3h),with the mortality rate of 11% and 67% respectively.Lesser cisteme compression predicts better outcome.GCS,pupil reflex,midline shift,and complex injury didn' t enter the logistic regression equation.According to compression time,90.5% of the cases' prognosis was accurately predicted,according to compression time and cisterne compression,95.2% was accurately predicted.Conclusion The mortality rate of severe traumatic brain injury with hernia was high and surgical intervention was effective.Decompression time and cisteme compression were the most important factors affecting prognosis in severe traumatic brain injury and they could predict prognosis of most cases correctly.

Antagonism, esterase isozyme ployacrylamide gel electrophoretic (EST-PAGE) and cluster analysis was used in the study of 14 strains of Ganoderma. The results showed that there were 18 bands of EST with different Rf. Cluster analysis at 50% similarity level showed that all strains could be clustered into five groups, the first included Xian zhi, Da xian 823, Nan han, Yuan zhi 6, Tian zhi, Han zhi; the second included Chi zhi 10, Chi zhi 12, Chi zhi, Ri ben hong zhi; the third included Zi zhi, Hei zhi; the fourth included Xue zhi; the fifth included Bai zhi. And this result was similar to the result of antagonism and morphological characters. Because of its stablity, the technique of EST can be used for identification of Gamoderma.

Objective To summarize the clinical characteristics of small intestinal stromal tumors(SIST), and evaluate the diagnostic values of various imaging or endoscope examinations for SIST. Methods From July 2004 to June 2009, 74 patients whose operation or endoscopy biopsy tissues pathologically confirmed SIST were collected. The clinical data, imageology including enteroclysis, abdominal ultrasound, spiral computered tomography (CT) and the double-balloon enteroscopy report of the patients were analyzed retrospectively. According to biological behavior, the SIST was divided into four risk degree such as extremely low risk, low risk, moderate risk and high risk. The correlation between pathologic characters and spiral CT feature was analyzed. Results The most predilection site of SIST was jejunum in 43 patients (58.1 %); secondarily duodenum in 17 cases (23%); and 10 cases (13.5%) in ileum. About 94.6 percent of patients (70/74) showed clinical signs, the most common symptom was gastrointestinal bleeding in 46 cases (67. 2 % ), abdominal pain in 23 cases (31.1%). Of various photogrammetry examinations and endoscopy, spiral CT has the highest diagnosis rate and diagnosis coincidence rate, which was 100% and 72. 1% respectively. Among the 74 SIST lesions, 14 cases were extremely low biological risk (18. 9 % ), 21 at low risk (28.4 % ), 15 at moderate risk (20. 3%) and 24 at high risk (32.4%). Spiral CT is helpful for the SIST risk diagnosis. Conclusions The onset of SIST was concealed and early diagnosis was very difficult. Spinal CT which could help to predict the tumor's risk degree and prognosis was noninvasive, convenient and reliable. Therefore, it could be the first choice for SIST examination at present.

Objective To establish a TaqMan probe-based real-time fluorescent quantitative PCR ( real-time PCR) for the quantitative and rapid detection of viral reservoir in peripheral blood mononuclear cells (PBMCs) isolated from rhesus monkeys with simian immunodeficiency virus (SIV) infection and to evaluate its preliminary application. Methods A pair of primers and one TaqMan probe were designed ac-cording to the conserved sequence of SIVmac239 strain for real-time PCR amplification. A length of 2 090 bp of nucleotide fragment was digested from the plasmid p239SpSp5 containing 5′-end long segments of SIV-mac239 strain by restriction enzymes EcoRⅠand SpeⅠ. The standards used for quantitative detection of SIV DNA in peripheral blood samples were prepared by a 10-fold serial dilution and used for graphing the stand-ard curve. The numbers of SIV DNA ( copies per 106 PBMCs) in rhesus monkeys during acute and chronic phases of SIVmac239 infection were determined and the virological characteristics of SIV DNA at different phages of infection were analyzed. Results A linear positive correlation between cycle threshold ( Ct) val-ues and concentrations (10 copies/μl to 109 copies/μl) of the standards was found. High levels of SIV DNA were monitored in SIV-infected monkeys 14 to 22 days after acute infection. The levels of SIV DNA in the acute phase of infection were about 1 to 2 logs higher than those in the chronic phase of infection. The num-bers of SIV DNA ( copies per 106 PBMCs) were 1 log lower than the SIV viral load in peripheral blood of the same monkey. The ratios of SIV DNA load to SIV RNA load ( DNA/RNA) in chronic phase of infection were higher than those in the acute phase. Conclusion The established TaqMan probe-based real-time fluorescent quantitative PCR was a highly sensitive and specific assay for the detection of SIV DNA with an advantage of wide linear range. It could be used for the quantitative evaluation of latent reservoirs of SIV.

Objective To investigate the clinical efficacy of intravitreal injection of Lucentis combined with pan retinal photocoagulation and trabeculectomy for neovascular glaucoma(NVG). Methods Seventeen eyes of 15 patients with NVG were treated by 0.5 mg Lucentis intravitreal injection first. Trabeculectomy was performed 7 days later and Pan retinal photocoagulation 2 weeks later. Iris,anterior chamber angle neovascularization,intraocu?lar pressure ,and visual acuity were observed in the following 6 months. Results Iris and anterior chamber angle neovascularization were completely regressed 7 days after the injection in 17 eyes. Six months after photocoagulation, 6 eyes had different degrees of improvement in visual acuity,10 eyes no change in visual acuity and 1 eye decreased from anterior index to immediate manual. There was significant difference in pre?treatment IOP and postoperative IOP( t = 12.75 ,10.26 ,9.73 ,10.77 ,P < 0.01 ). No serious complications were observed after intravitreal injec?tion and trabeculectomy. Conclusions Intravitreal injection of Lucentis could significantly accelerate the regres?sion of iris and anterior chamber angle neovascularization ,which could improve the successful rate of trabeculecto?my and pan retinal photocoagulation. Intravitreal injection of Lucentis combined with trabeculectomy and panretinal photocoagulation is safe and effective for NVG.
