Objective To observe the clinical efficacy of Kuijiening Paste acupoint application on ulcerative colitis (UC) patients of spleen-kidney Yang deficiency type, and its effect on serum levels of IFN-γand IL-4. Methods Sixty UC patients were divided into treatment group, control group and combined treatment group, 20 cases in each group, and were given Kuijiening Paste acupoint application plus placebo, oral sulfasalazine plus comfort paste and Kuijiening Paste acupoint application plus sulfasalazine respectively for 60 days. The clinical efficacy, mucosal lesions efficacy, mucosal pathology efficacy, changes of serum IFN-γand IL-4 were observed after treatment. Results There was no significant difference in clinical efficacy, mucosal lesions efficacy and mucosal pathology efficacy among the three groups (P>0.05). After treatment, IFN-γlevels of the three groups significantly reduced, and IL-4 levels significantly increased (P<0.01). The difference between the treatment group and the control group was significant (P<0.05). The difference between the combined treatment group and the control group was significant (P<0.01). Conclusion Kuijiening Paste acupoint application combined with sulfasalazine can regulate the level of immune cytokine in UC patients of spleen-kidney Yang deficiency type, and receive good clinical efficacy.

Objective To investigate the early diagnosis and treatment of pneumocystosis after renal transplantation. Methods The clinical data of 6 cases of renal transplant recipients from 2000-2001 who developed pneumocystosis were discussed. Results Six patients were diagnosed as having pneumocystosis and subjected to the treatment of SMZ_ CO (SMZ 60-70 mg/kg daily, TMP 12-14 mg/kg daily) for 3 weeks. Immunosuppressive regimene was regulated. Except one case died due to abandonment of treatment, the remaining 5 cases were cured and had normal renal function. Conclusion The diagnosis of pneumocystosis was established by visualization of pathogen in bronchialveolar lavage (BAL) samples. SMZ_ CO is still the most commonly used drug for pneumocystosis at present and administration for individual is important because of its renal toxicity. The dosage of immunosuppressive agent for each patient with pneumocystosis must be adjusted.

Objective To explore the value of multi-model reconstruction of 16-slice spiral CT in diagnosis of rib fractures.Methods 16-slice spiral CT volumetric scanning was performed in 72 patients with rib fracture proved by clinical,all images were reconstructed in thin slice and transferred into ADW4.1 workstation.Images such as multiplanar reconstruction(MPR),maximum intensity projection(MIP)and volume rendering(VR)were performed,then the reconstructed images of injured ribs were observed and analyzed by two experienced radiologists and compared with radiographs.Results In 72 cases,there were 217 rib fracture and 7 costal cartilage fracture depicted on MSCT.The location and number of fracture and displacement of fracture could be showed clearly on images of multi-model reconstruction.VR images were betten in demonstration of the anatomical structure,MPR images were better to show the minor lesion of rib fracture,MIP was the best imaging method in detecting the costal cartilage fracture,while axial image was the basic CT scanning section.Radiographs revealed 169 rib fractures but no costal cartilage fracture.Conclusion 16-slice spiral CT of multi-model reconstruction is superior to radiography in diagnosis of rib fracture and costal cartilage fracture.But the combinalion of various reconstruction techniques should be acquired.

Objective To assess the application value of real time three-dimensional (RT-3D) ultrasonography in diagnosis of fetal corrected transposition of the great arties (cTGA). Methods Data of 14 fetuses diagnosed as cTGA clinically were reviewed. With 2D ultrasonography, diagnosis views were obtained and then studied using cardiac three-section analytic method. With real time 3D (RT-3D) ultrasonography, volume datasets were acquired at the level of four chamber view, and spatio-temporal image correlation (STIC) was then used to analyze the relationship of the two great arties. Confirmed by infant echocardiography and the autopsy findings, the accuracy of RT-3D and 2D ultrasonography in evaluation of fetal cTGA and complications were compared. Results The accuracy rate of RT-3D and 2D ultrasonography in diagnosis of fetal cTGA was 92.86% and 71.43% (χ~2=2.19, P=0.14). The procedure time of RT-3D ultrasonography was significantly shorter than that of 2D ultrasonography (t=10.23, P＜0.001). Conclusion RT-3D ultrasonography can evaluate fetal cTGA and its complications more quickly and exactly than conventional 2D ultrasonography.

Objective To evaluate the value of prenatal ultrasound in the interrupted aortic arch (IAA), and analyze the reasons of misdiagnosis and improve diagnostic ratio of this kind of defects. Methods Ultrasonic characteristics were analyzed in 16 fetuses with aortic arch anomalies, which were compared with ultrasound image and autopsy results of the normal fetus. The relativity of fetal IAA and abnormal chromosome was also analyzed. Results Among the 16 cases, 15 cases were confirmed by anatomy and the accuracy of ultrasound diagnosis was 94% (15/16), of which one case was serious constriction of aortic arch, one case was error type, three cases were obtained explicit type due to unsatisfactory results of prenatal ultrasound. The coincidence rate of ultrasonic type was 73% (11/15). All of the corrected diagnosed cases were detected with ventricular septal, of which 5 cases were detected with complete endocardial cushion defect, 9 cases were found extra cardiac malformations. Among the 7 karyotype check cases, 3 cases were diagnosed with Trisomy 18, 1 case Trisomy 13, while the rest 3 cases normal. The incidence rate of Trisomy 18 was 43 % (3/7). Conclusions Prenatal ultrasound shows a high accuracy in diagnosing fetal interrupted aortic arch (IAA ), but there’s a need to be improved in explicit typing. It is difficult to identify fetal interrupted aortic arch (IAA) and serious constriction of aortic arch (COA). The incidence rate of Trisomy 18 in the abnormal chromosome of fetal IAA is high.

OBJECTIVETo observe the clinical efficacy differences among warming-promotion acupuncture, regular acupuncture and psychological care for post-earthquake depression.

METHODSNinety cases of post-earthquake depression in Gansu province were randomly divided into a warming-promotion acupuncture group, a regular acupuncture group and a care group, 30 cases in each one. The psychological treatment was applied in the care group; the regular acupuncture at Baihui (GV 20), Sishencong (EX-HN 1)), Fengchi (GB 20), Shenmen (HT 7), Yang-lingquan (GB 34), Taichong (LR 3) and Sanyinjiao (SP 6) was used in the regular acupuncture group; based on the treatment of regular acupuncture group, the warming-promotion acupuncture was applied in the warming-promotion acupuncture group, once a day. Ten days were taken as one course with an interval of two days between two courses. Totally 3 treatment courses were completed. The Hamilton depression (HAMD) scale before and after treatment in each group was observed while the efficacy was analyzed.

RESULTSAll three treatments were effective for depression. The total cured rate was 86.67% (26/30) in the warming-promotion acupuncture group, which was obviously superior to 50.00% (15/30) in the regular acupuncture group (P < 0.01) and 33.33% (10/30) in the care group (P < 0.001). After the treatment, the score of HAMD was all reduced in three groups, in which the effect in warming-promotion acupuncture group was superior to that in the regular acupuncture group and care group (9.02 +/- 2.37 vs 10.73 +/- 2.28 and 11.05 +/- 2.01, P < 0.05, P < 0.01).

CONCLUSIONThe warming-promotion acupuncture has positive effect on post-earthquake depression, which has special effect and is worthy of clinical generalization and application.

ObjectiveTo investigate the action mechanism of CD20 lymphocyte infiltration in the renal allograft biopsy with chronic allograft nephropathy (CAN).MethodsCAN cases confirmed by renal biopsy within 2 years after renal transplantation served as study subjects. By using immunohistochemistry,the deposition of C4d and the CD20-positive lymphocytes infiltration in the renal grafts were examined.The clinical follow-up data were analyzed.ResultsForty-four cases of CAN were enrolled in the study, including 13 cases (29.5％ ) of CD20-positive lymphocytes infiltration,and 31cases (70.5％ )of CD20-negative lymphocytes infiltration. CD20-positive lymphocytes in biopsy showed nodular and scattered lymphocytes infiltration.There were 5 (26.3％)cases of CAN Ⅰ,4 cases (25.0％) of CAN Ⅱ,and 4 (44.4％) of CAN Ⅲ in CD20-positive group.There was no statistically significant difference between the only CAN group and CAN with AR group in CD20-positive rate.Immunohistochemical staining showed there were 12 cases (27.3％) with C4d linear deposition in peritubular capillary endothelial cells (PTC).C4d positive rate had no significant difference among the CAN classifications. There was no significant relationship between C4d deposition and CD20-positive lymphocytic infiltration.The average serum creatinine in CD20-negtive group and CD20-posigtive group was 140.8 ± 22.0 and 183.5 ± 25.5μmol/L before biopsy,and 165.6 ± 37.6 and 242.2 ± 59.1 μmol/L one year after biopsy.The average serum creatinine level in CD20-positive group was higher than in CD20-negtive group before and after biopsy.ConclusionProgressive chronic humoral immunity is high risk in the process of CAN. The CD20-positive lymphocyte infiltration has no relevance with CAN grade and C4d deposition in PTC,but is associated with circulating antibody PRA and allograft long-term outcome. Pathogenetic mechanism may not contribute to chronic humoral immune,but B cells presenting donor antigens,are recognized and activated by T cells as antigen-presenting cells.
