Objective To evaluate the clinical application of postprocessing technique of spiral CT images in chest diseases.Methods Chest spiral CT was performed in 105 cases and 10 normal controls.The postprocessing images were done using software and compared to conventional CT, fiberoptic bronchoscopy, operation and pathological results. Results The postprocessing images had better MPR and 3D view of organs, nice contrast between of lesion and sorroundings structures.This postprocessing techniques provided more informations in observing and analysing the chest disease.Conclusion Postprocessing technique of spiral CT images is an important complimentation for 2D CT analysis, and has many advantages especially on thoracic disease diagnosis,but they should be applied in combination with two-dimensional CT to achieve accurate diagnosis.

Objective To observe the ultrasonic manifestation of metatarsal fatigue fractures and probe into the clinical values of ultrasonic diagnosis and follow-up to the disease.Methods The clinical data and sonographic features of 30 cases with metatarsal fatigue fracture confirmed by X-ray and CT were analyzed retrospectively.Results All the subjects in this study were metatarsals insufficiency fractures located in the second or third diaphysis.2D-ultrasound found microfracture in the cortex and the periosteal elevation by increased vascularity in the early stage.During the 3-month follow-up,thickened cortex and callus shown as the shape of mushroom or cauliflower and a great amount of neovascularisation were visualised with color Doppler flow imaging.Then,the cortex surface became gradually changing from rough to smooth and obvious posterior shadows were observed with the illness progression.Conclusions Ultrasonography could be used to detect the cortical continuity,callus characteristics and blood flow perfusion of fatigue fracture in the different damage stages.

Objective To investigate whether gemcitabine (GEM) could enhance radiosensitivity of human non-small cell lung cancer cells and its related mechanism.Methods Clonogenic assay was used to analyze radiosensitivity enhancement by GEM on p53 mutant human lung adenocarcinoma cell line 973.Alterations of cell cycle distribution and apoptosis were measured by flow cytometry.Results Mild radiosesitizing effect was observed when 10 nmol/L GEM was administrated before or after irradiation.Marked radiosesitizing effect was demonstrated when 100 nmol/L GEM was administrated before or after irradiation, with much stronger effect of pre-irradiation GEM treatment.Mutation of p53 gene affected cell cycle redistribution and cell apoptosis, but had no relationship with radiosensitivity enhancement of GEM.Conclusions 100 nmol/L GEM could significantly enhance radiosensitivity of human lung cancer cells.However, this effect may not be associated with p53 gene mutation, cell cycle redistribution or cell apoptosis.

Objective To evaluatethe curative effect of the integrative treatment of point injection, warm acupuncture and Chinese medicine enema for the chronic pelvic inflammatory disease.Methods A total of 86 patients with chronic pelvic inflammatory diseasewere divided into control group and treatment group, 43 patients in each group , according to the random number table. The control group was treated by warm acupuncture combined with Chinese medicine enema, while the treatment group was treated with point injection plus the basis of control group. The levels of serum CRP, IL-1 and IL-6 were detected by enzyme linked immunosorbent assay,the plasma viscosity and hematocrit were detected by automatic blood rheological test instrument,the symptom scores of 2 groups were compared before and after treatment, the clinical efficacy was evaluated and the recurrence rate was observed. Results The clinical effective rate of treatment group patients was 97.7% (42/43), and the control group 81.4% (35/43). The difference between two groups was significant (χ2=6.081,P=0.014). After treatment, the levels of CRP (7.53 ± 3.44 mg/L vs. 10.11 ± 3.02 mg/L,t=-3.696), IL-1β (26.37 ± 13.98 pg/mL vs. 36.33 ± 4.02 pg/mL,t=-4.490) andIL-6 (23.31 ± 10.11 pg/mlvs. 29.56 ± 4.27 pg/ml,t=-3.734)in the treatment group were significant lower than those in control group (P<0.05). The scores of pain (2.13 ± 0.55vs.2.71 ± 0.62,t=-4.589), tiredness (1.07 ± 0.98 vs. 2.53 ± 0.52,t=-8.630), Body cold (1.51 ± 0.51 vs. 2.21 ± 0.67,t=-5.451), menstrual symptoms (1.27 ± 0.97 vs. 2.29 ± 0.78, t=-5.374) and total points (6.13 ± 3.94vs. 8.55 ± 1.82,t=-3.656) in the treatment group were significant lower than those in control group (P<0.05). The plasma viscosity (1.13 ± 0.25 mPa?svs. 1.41 ± 0.32 mPa?s,t=-4.521) and the red blood cells deposited (0.27% ± 0.08% vs. 0.41% ± 0.07%,t=-8.636) in the treatment group were significant lower than those in control group (P<0.05). The recurrence rate of treatment group was none, while 11.43% (4/35) in control group. Thus, the recurrence rate of treatment group was significantly lower than the control group (χ2=5.063,P=0.024). Conclusions The integrative treatment of point injection, warm acupuncture and Chinese medicine enema can reduce the level of inflammatory factors in patients with chronic pelvic inflammatory disease, improve the blood microcirculation, and reduce the recurrence rate.

Results Definitive diagnosis were obtained 215 times in 204 patients (233 times) with abdominal CEUS. The diagnostic accuracy of CEUS was 92.27%, significant higher than that of conventional ultrasonography (62.23%). Anaphylactic shock happened 1 time (0.43%) in 1 patient. Conclusion CEUS with SonoVue can provide a high diagnostic accuracy with relatively safety of the possibility of serious adverse event.

Objective To evaluate the diagnostic advantages of contrast-enhanced ultrasonography in experimental abdominal blunt trauma in comparison of routine ultrasonogrphy. Methods Liver, spleen and kidney blunt trauma models were established in 10 canines and 12 rabbits. Both routine ultrasonography and contrast-enhanced ultrasonography were performed to identify the possible injury. Accuracy of the two ultrasonic technologies was compared in diagnosing each kind of organ and various injury degrees. Results Fifty-six trauma models including 22 livers, 14 spleens and 20 kidneys were established. There was significant difference between two ultrasonic methods in diagnosing liver, spleen and kidney injury (P<0.01);and contrast-enhanced ultrasonogarphy had particular advantage in detecting minor injuries of Ⅰ-Ⅱ scale (P<0.01). Conclusion Contrast-enhanced ultrasonography greatly enhances diagnostic accuracy of blunt abdominal solid organ trauma, especially in minor injuries.

Objective:To study the difference in anti-hepatic fiborsis components between pre-and post-processed Trionyx Sinensis Carapace to guide the clinical application of Trionyx Sinensis Carapace. Methods:SDS-PAGE gel electrophoresis was used to compare the constituents in pre-and post-processed Trionyx Sinensis Carapace, and the inhibitory effect on the proliferation of HSC-T6 was deter-mined by MTT. Results:The processed Trionyx Sinensis Carapace had much more components than the crude Trionyx Sinensis Cara-pace,and the relative molecular mass in the first-level band decreased resulting in the generation of micromolecular polypeptides. Both pre-and post-processed Trionyx Sinensis Carapace had anti-hepatic fibrosis, while the vinegar-processed Trionyx Sinensis was more ef-fective. Conclusion:The difference in the active components in pre- and post-processed Trionyx Sinensis Carapace is obvious, which provides foundation for the clinical application and further researches.
