ObjectiveTo study the feasibility and reasonability of low-dose multi-slice CT(MSCT)with three dimensional rendering of the tendons of foot and ankle. The statistical methods including ANOVA and Kruskal-Wallis H was used. MethodsForty-five consecutive patients with fractures of foot and ankle were enrolled and evenly grouped into A (80 kV, 100 mAs), B(110 k V ,60 mAs) and C (130 kV,60 mAs).The MSCT scanning range was 6 slices of 1.0 mm. The CT value and standard deviation (SD) of the muscle and the CTDIvol were recorded. The image quality of volume rendering of the tendons was blindly evaluated.ResultsThe CT value of muscle in group A (71.6 ± 12.0) HU was significantly higher than group B [(66.8±9.2) HU, P=0.010]and C[(66. 1 ±7. 1) HU, P =0.004]. The SD average values were 11.9, 6. 1 and 7.0 HU for three groups, and there were significant differences among the three groups(F =37. 142, P=0. 0000). Group A had the highest SD value, group C had the lowest SD;CT1DIvol average value were (3.01 ± 0. 08) , (4. 63 ± 0. 11), (7.02 ± 0. 24) mGy respectively, which were significant different among the three groups (H =39. 185, P =0. 000). Group A had the lowest CTDIvol, while group C had the highest CTDIvol. Volume rendering of the tendons was evaluated as 2.3 ± 0. 5、3.7 ± 0. 5、4. 8 ±0. 4, and there were significant differences among the three groups (H = 72. 779, P = 0. 000). Group A had the worst VR images, while group C had the best VR images.All VR images in Group B were good for diagnosis. ConclusionThe protocol of 110 kV, 60 mAs, and 1 mm × 6 with three-dimensional volume rendering would be enough for evaluating the tendons of foot and ankle.

Conclusion The effect of type 2 diabetes on the collagen in different organs is different. The collagen content decreases in the femoral and skin tissue but increases in the liver.

Objective To study the clinical effect ofKangyan-Yihao on facial steroid-dependent dermatitis.Methods 63 patients of steroid-dependent dermatitis in ShuGuang Hospital Affiliated to Shanghai University of TCM were recruited and randomly divided into a treatment group with 32 patients and a control group with 31 patients. Patients in both groups were forbidden to use hormone treatment and taken cetirizine 10 mg orally every night. On this basis, the treatment group was treated withKangyan-Yihao prescription and the control group was treated withTianQing-Fuxin. The total curative effects, itching-reliving degree and life quality were compared between the two groups after the treatment after two weeks.Results After the treatment, the EASI score, DLQI score skin itching score in the treatment group(2.41±2.64, 4.93±2.90, 1.07±0.83, respectively) were better than those in the control group(2.52±2.73,5.07±3.59, 1.30±0.65,P<0.01 orP<0.05).ConclusionsKangyan-Yihao has a significant effect in treating facial steroid-dependent dermatitis, specially for the oily and pustule lesions.

OBJECTIVETo investigate whether the genistein can increase the radiosensitizing effect on laryngeal squamous carcinoma Hep-2 cells.METHODS Hep-2 cells were treated with genistein, radiation, and genistein plus radiation respectively. DMSO was used as the control group. EdU assay was performed to assess the short-term effect of genistein and (or) radiation on the proliferation of Hep-2 cells. Clonegenic assay was used to detect the survival rate of Hep-2 cells after treatment with radiation doses of 0, 2, 4, 6, 8 Gy and radiation combined with genistein. The data was fitted into the classic single-hit multi-target mathematical model to analyze the long-term effect on cell proliferation death of Hep-2 cells.RESULTSIt was observed that radiation combined with genistein could significantly inhibit the proliferation of Hep-2 cells. And the SER of 10μmol/L genistein was 1.412.CONCLUTIONGenistein can inhibit the proliferation of Hep-2 cells by DNA synthesis inhibition, and can be an adjunct agent of radiotherapy.

Objective Via observing concentration changes of interleukin(IL)-1β, IL-6 and IL-18 in hippocampus of pilocarpine treated rats after intranasal delivery of transforming growth factor-β1(TGF-β1), to explore the possi-ble anti-epileptogenic and neuro-protective role of TGF-β1 in the epiletogenesis progression. Methods Three hours after pilocarpine induced status epilepticus, rats were treated with recombinant human TGF-β1 or the same volume of PBS by intranasal administration. Animals were executed, harvested at 24, 48, 72 h after SE individual-ly. Using the methods of the enzyme-linked immunosorbent assay (ELISA) and immunohistochemisty (IHC), the concentrations and distribution of IL-1β, IL-6, IL-18 were detected in hippocampus. Results TGF-β1 could re-duce the expression of IL-1β and IL-6 in the hippocampus of pilocarpine treated rats effectively (P<0.05 or P<0.01), however, TGF-β1 did not affect the expression of IL-18 significantly( P >0.05). Conclusion By the supplementation of intranasal TGF-β1, classical pro-inflammatory cytokine ( IL-1β, IL-6) are remarkably sup-pressed, TGF-β1 may exert antiepileptogenic and neuropretective effects.

Objective To compare the effects of classic intrafascial supracervical hysterectomy(CISH)and laparoscope-assisted vaginal hysterectomy(LAVH)on structure and function of the pelvic floor in women.Methods From March 2003 to December 2005,totally 35 cases of CISH and 44 cases of LAVH were performed in our hospital.The patients were followed up for 22 to 38 months after the operations.During the period,they received physical examination and life quality questionnaire,by which the degree of pelvic organ prolapse and pelvic floor function were evaluated.Results The incidence of cystocele in CISH group was significantly lower than that in LAVH group [11.4%(4/35)vs 34.1%(15/44),?2=5.481,P=0.019],whereas,no significant difference was found in the incidence of rectocele between the two groups [17.1%(6/35)vs 13.6%(6/44),?2=0.186,P=0.666].Seven(15.9%)patients in the LAVH group developed cervix prolapse,while none of the CISH group had such a situation(P=0.016).Life quality questionnaire showed that 5 patients in CISH group and 16 patients in LAVH group were satisfied with their sexual life [14.3%(5/35)vs 38.1%(16/42),?2=5.456,P=0.019].Conclusion CISH is superior to LAVH in protecting the structure and function of the pelvic floor.
