BACKGROUND: The efficacy of Cyclosporin A(CyA) in the treatment of psoriasis is well recongized, the dosage less than 5mg/kg per day(mg/kg/d) is recommended. OBJECTIVE: The purpose of this study is to evaluate the indication, dose, course and side-effects of CyA therapy for psoriasis, especially in China. METHODS: Forty patients with psoriasis were treated with doses of CyA 5mg/kg/d, compared with 20 patients treated with Tigason lmg/kg/d by Global PAST. RESULTS: 1. Of 40 patients 33 patients (82.5%)were cured clinically in 4-5weeks and all the patients(100%) had responses to the therapy. 2. The efficacy and the Global PASI reduction of CyA therapy were significantly better than that of Tigason therapy. 3. During the CyA therapy, no severe side-effects and obvious laboratory changes were found. CONCLUSION: CyA(5mg/kg/d) was satisfactory for psoriasis, especially for psoriasis pustulosa, arthropathica and erythroderma. CyA was found to be superior to Tigason. The therapy course and side-effects seemed to be related to the dosage.

Total 118 patients with pyogenic liver abscess admitted to Zhongshan Hospital were classified into pypgenic liver abscesses of cryptogenic origin (PLAC,n =54),pyogenic liver abscesses of biliary origin (PLAB,n =48) and pyogenic liver abscesses of hemagenous origin (PLAH,n =16)according to the causes.The clinical features of three groups were compared and analyzed.The results showed that no statistically significant difference existed among three groups in clinical manifestation and signs.Compared to PLAB,the abscesses in right lobe of liver were more common in PLAC,diabetes mellitus was more prevalent in PLAC,but the co-existing diseases including chronic liver disease,non biliary malignant tumor and ALP elevation were less in PLAC.Klebsiella pneumoniae was frequently detected in PLAC,but there was no significant difference comparing to other two groups.No significant difference was found among three groups in the choice of therapeutic methods,the course of antibiotics,length of hospital stay and the days from admission to diagnosis.

The clinical data of 118 patients with bacterial liver abscess admitted to a tertiary hospital from January 2007 to December 2009 were analyzed retrospectively.Etiology study showed that 45.8％(54/118) cases of bacterial liver abscess were cryptogenic,40.7％ (48/118) were biliary source and 13.5％ (16/118) were hematogenous.The positive rate of pus culture was 57.1％ (36/63),among which klebsiella pneumoniae accounted for 72.2％ (26/36).The positive rate of blood culture was 31.2％(20/64) and klebsiella pneumoniae accounted for 95％ (19/20).One hundred and sixteen patients (98.3％) underwent color ultrasound examination with an accuracy rate of 93.2％.84 patients (71.2％)underwent the CT scan with an accuracy rate of 95.3％ and 20 patients underwent MRI with an accuracy rate of 85％.Seventy five patients (63.6％)accepted ultrasound-guided percutaneous aspiration and catheter drainage combined with antibiotic therapy; 40 patients(33.9％)were treated with antibiotics alone.On the discharge 27 patients(22.9％) achieved clinical cure,87 patients (73.7％) were classified as effective,4 patients (3.4％) had no effect and no death in this group of patients.The average length of hospital stay was 16 days.Cryptogenic was the most common cause of bacterial liver abscess,biliary source took the second place.Kleibsiella pneumoniae was the predominant organism.Detailed medical history inquiry,physical examination and assistant examination may increase the accuracy rate of diagnosis.Needle biopsy should be performed if necessary.Ultrasound-guided percutaneous aspiration and catheter drainage combined with antibiotics should be the first-line treatment.

Objective To investigate the relationship between breast cancer and G919A polymorphisms of CBS (cystathionine β synthase) in patients with breast cancer in Han nationality in Xinjiang. Method Three hundred breast cancer patients and 300 normal controls of Han nationality were genotyped by ARMS method, and then the relative biochemical indicators were detected by the automatic biochemical analyzer. Results The Hcy level of breast cancer patients were higher than that of control group (P < 0.05). Genotypes GG, GA, AA of CBS G919A and allele G,A, in breast cancer patients were 63.7%, 24%, 12.3% and 75.7%, 24.3% respectively, which had no statistically significance when compared with those of the controls (P > 0.05). Conclusion The high level of Hcy may be a risk factor for breast cancer in Han nationality in Xinjiang and there was no relationship between CBS G919A polymorphism and breast cancer.

OBJECTIVE:To observe therapeutic efficacy of Jiangu tongxiao pills in the treatment of osteoarthritis. METH-ODS:72 patients with osteoarthritis were randomly divided into treatment group and control group with 36 cases in each group. Treatment group was given Jiangu tongxiao pill orally,5 g/time,3 times/d;control group was treated with Glucosamine sulfate capsules orally. 0.5 g/time,3 times/d. A treatment course lasted for 7 days,and both group received 4 treatment courses. Clinical ef-ficacy,WOMAC score and VAS score were observed and compared between 2 groups. RESULTS:The total effective rate of treat-ment group(94.44%)was obviously superior to that(83.33%)of control group,with statistical significance(P<0.05). WOMAC score and VAS score of treatment group were lower than those of control group,with statistical significance(P<0.05). CONCLU-SIONS:Jiangu tongxiao pills has good therapeutic efficacy for osteoarthritis.

AIM: To investigate the phenomenon that miR-let-7d regulates the proliferation and invasion abilities of the lung cancer cells through nuclear receptor peroxisome proliferator-activated receptors γ (PPARγ).METHODS: The relation between PPARγ and microRNA was analyzed by bioinformatics.The plasmid reporter assay was used to verify that PPARγ was the target of miR-let-7d.The lung cancer cell line with low expression of PPARγ was selected from different lung cancer cell lines by Western blot.The regulatory role of miR-let-7d in the lung cancer cells was determined by dual luciferase labeling and Western blot.The effect of miR-let-7d on the proliferation ability of lung cancer cells was detected by colony formation assay, the effect of miR-let-7d on the invasive ability of lung cancer cells was detected by Transwell invasion assay.RESULTS: The results of bioinformatic analysis showed that miR-let-7d regulated the expression of PPARγ, and the 3'UTR of PPARγ contained 2 functional miR-let-7d binding sites, indicating that PPARγ is a direct target of miR-let-7d.miR-let-7d was able to directly regulate the expression of PPARγ at mRNA and protein levels.Transfection of miR-let-7d inhibitor promoted the proliferation and invasion abilities of lung cancer cells by increasing the expression of PPARγ.CONCLUSION: miR-let-7d increases the expression of tumor suppressor PPARγ to inhibit the proliferation and invasive abilities of lung cancer cells.

This difference was statistically significant ( P

A master-slave electrical impedance tomography (EIT) system for body complex impedance based on digital signal processor (DSP) is designed in this paper. Used as the master computer, a PC performs the image reconstruction and display on time, while DSP carries out such tasks as electrode selection, data acquisition and data communication with the master. Based on DDS technique, the signal generator can create the sine wave signals, and it's amplitude, frequency and phase can be continuously adjusted. The designed feedback unit can improve the linearity and the stability of the voltage-controlled current source effectively. Undersampling technology and digital demodulation technology are used in this system in order to attain the information of real and imaginary components of the body complex impedance. Back projection method is adopted to reconstruct the image in this system. Experimental results show that this system improves the data acquisition speed and the image resolution.
