Objective To evaluate the clinical value of multi-tomographic imaging mode of three-dimensional ultrasound combined with surface imaging in diagnosing and staging bladder tumors.Methods Seventy-five patients were examined with three-dimensional ultrasound and two-dimensional ultrasound.In addition,54 cases were undergone preoperative multislice spiral CT.All cases were proved by pathology after operation.Results The qualitation accuracy in the diagnosis of bladder tumor with two-dimensional ultrasound was 93.3%(70/75) and that of three-dimensional ultrasound was 98.7%(74/75).The staging accuracy rates with two-dimensional ultrasound and three-dimensional ultrasound were 83.5%(106/127) and 93.2%(123/132) respectively.The difference of bladder tumor staging between three-dimensional ultrasound and two-dimensional ultrasound was significant (P＜0.05).The qualitation accuracy in the diagnosis of bladder tumor with CT was 90.7%(49/54).The preoperative staging rate of CT was 79.7%(59/74),compared with that of three-dimensional ultrasound,the difference was significant(P＜0.05).Conclusions Multi-tomographic imaging mode of three-dimensional ultrasound combined with surface imaging can provide useful information and makes an improvement in detecting and staging bladder tumors.

Objective To discuss the diagnosis and surgical management of multilocular cystic renal cell carcinoma (MCRCC) and to evaluate the gene function of the mutation of von Hippel-Lindau (VHL) gene in MCRCC. Methods Seventeen MCRCC cases (11 men and 6 women) out of 512 cases of renal cell carcinoma from 2000 to 2010 were retrospectively analyzed. The mean age of the 17 patients was 46 years (37-61 years). Ultrasonography and CT were available in all 17 cases, and 1 case was misdiagnosed as parapelvic renal cyst. The mutation of VHL gene was detected by PCR in the specimens of can-cerous tissue and adjacent normal tissue from 11 cases of MCRCC. Results Three of 17 cases underwent nephron sparing surgery, the others underwent radical nephrectomy. One case underwent unroofing of parapelvic renal cyst, but the rapid frozen pathology of the cyst wall showed renal cell carcinoma of clear type. As a result, radical nephrectomy was eventually performed. All 17 cases were confirmed as MCRCC by eva-luating pathological characteristics, such as the cyst wall lined by single or several layers of clear tumor cells and the nuclei which were small and anachromasis. Clinical stages of all cases were T1N0M0, in which there were 14 cases with pathological T1G1 and 3 cases with pathological T1G2. All patients underwent a follow-up of 9 to 36 months (mean, 12 months) without recurrence or metastasis. Mutation of VHL gene was detected in 7 of 11 cases (64%), but all adjacent normal tissues were negative. Conclusions As a rare subtype of renal cell carcinoma, MCRCC is difficult to diagnose. CT is an essential measure in diagnosis of MCRCC preoperatively. Because of the good prognosis of reported cases, nephron sparing surgery for the treatment of MCRCC is recommended. VHL gene mutations may play an important role in the carcinogenesis of MCRCC.

Background and purpose:Carcinoma of the kidney is the most common malignant renal parenchymal carcinoma;its biological behavior is extremely complicated and is not sensitive to radiotherapy and chemotherapy.Studies have shown that the hypoxia-inducible factor HIF1-? and HIF2-? are related to the occurrence and development process of the clear-cell carcinoma of kidney.So,we intend to construct psilencer3.0-HIF-? siRNA recombinant plasmid in this study through RNA interference method,thereby providing an effective tool for further exploration of the role of HIF in the occurrence and development of clear-cell carcinoma of kidney.Methods:Design and chemically synthesize the DNA fragments of coding HIF-1? and HIF-2? siRNA and make them up into siRNA expression vector through gene recombination.Adopting the real-time quantitative PCR and Western blot tested the inhibitive effect of the constructed siRNA expression vector on mRNA and protein levels on the target gene expression.Results:After 786-0 cells transfecting with psilencer3.0-HIF-1?siRNA and psilencer3.0-HIF-2?,the inhibitory rate of mRNA expression of HIF-1? and HIF-2? reached 82.1% and 87.4% respectively,and OS-RC-2 cells transfecting psilencer3.0-HIF-1? siRNA and psilencer3.0-HIF-2?,the inhibition rate reached 91.2% and 81.2% respectively.The protein expression of the experimental group with 786-0 cells and OS-RC-2 cells transfecting HIF-1? interference plasmid and HIF-2? interference plasmid were lower at different levels than that from the blank control group.Conclusions:The constructed siRNA expression vector can effectively inhibit the expression of target gene HIF-1 and HIF-2 at mRNA and protein levels.

Objective Thymoma is associated with autoimmune diseases. We retrospectively analyzed the clinical characteristics of thymoma complicated systemic lupus erythematosus (SLE). Methods Patients were from Qilu Hospital Shandong University between June 2004 and June 2014, and satisfied classification criteria of American College of Rheumatology (ACR) classification criteria 1997 for SLE. Thymoma was diagnosed by chest CT scan. Results Nine cases were of thymoma complicated with SLE, with the male:female ratio of 1∶8. The age of SLE onset was (48±19) years, age of thymoma discovery was (47±19) years. The follow-up period was 3 to 10 years. Three cases (33%) were benign thymoma and underwent thymectomy and verified by histopa-thology test. One case presented thymoma 9 years after SLE, 5 cases (56%) presented SLE and thymoma simultaneously, 3 cases (33%) presented SLE after thymectomy. Clinical manifestations of SLE included 4(44%) skin lesions, 8(89%) polyarthritis, 5(56%) nephritis, 3(33%) leukocytopenia, 3(33%) throm-bocytopenia, 2 (22%) of interstitial pneumonia, 4 (44%) pleural effusion, no neuropsychiatric systemic lupus erythematosus. Nine cases (100%) were ANA positive, 7 (78%) were anti-dsDNA positive. Conclusion SLE complicated thymoma usually occurs in relatively older age, tend to present with multi-systemic presentations, and high percentage of anti-dsDNA positivity.

OBJECTIVE: To study the effects of two epiphyseal stimulating procedures on local growth of long bone in rabbits. METHODS: Osteotomy was performed in the metaphysis near the proximal tibial epiphyseal plate and hemicircumferential periosteal excision was made on the proximal tibial epiphysis. Tibia roentgenography, tetracycline labelling, histological method and electron microscopy were used. RESULTS: The local stimulating effect following the hemicircumferential periosteal excision was more remarkable than the osteotomy. CONCLUSIONS: Periosteal excision is a better treatment for children's knee deformity.

OBJECTIVETo evaluate the efficacy and safety of tiaogan Lipi Recipe (TLR) in treating non-alcoholic fatty liver disease (NAFLD) patients of Gan stagnation Pi deficiency syndrome (GSP-DS).

METHODSA randomized, double blind, placebo-controlled clinical trial was performed. Totally 99 NAFLD patients of GSPDS were randomly allocated into two groups, 66 patients in the treatment group (treated with-TLR, one dose per day) and 33 patients in the control group (treated with placebos, one dose per day). The therapeutic course for all was 12 weeks. All patients received lifestyle interventions including moderate aerobic exercise, moderate caloric restriction, and dietary changes. Clinical symptoms, CT indices, liver functions and blood lipids were observed before and after treatment.

RESULTSAfter 12 weeks of treatment, the total score of clinical symptoms decreased in the two groups (P <0. 01), and it was lower in the treatment group than in the control group (P <0. 05). Liver/spleen CT ratio increased in the treatment group (P <0. 01), and it was higher in the treatment group than in the control group (P <0. 01). After treatment levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transferase (GGT) all decreased in the treatment group (P <0. 05, P <0. 01), while levels of ALT decreased in the control group (P <0. 05). Besides, all the 3 levels mentioned above were lower in the treatment group than in the control group (P <0. 05). Levels of total cholesterol (CHO) and triglyceride (TG) decreased in the two groups (P <0. 05), and they were lower in the treatment group (P <0. 05). Total effective rates of TCM syndrome, abdominal CT, liver functions, and blood lipids were 79. 69% (51/64 cases), 54. 69% (35/64 cases), 67. 65% (23/34 cases), and 67. 39% (31/46 cases) in the treatment group, while they were 56. 25% (18/32 cases), 25. 00% (8/32 cases), 33. 33% (6/18 cases), and 55. 56% (10/18 cases) in the control group. All were superior in the treatment group (P <0.05, P <0.01, respectively).

CONCLUSIONTLR combined with lifestyle intervention could safely and effectively improve clinical symptoms of NAFLD patients of GSPDS, elevate liver/spleen CT ratios, and play a role in liver protection, anti-inflammation, and lowering blood lipids.

Objective To observe the application of mtDNA COI genes in common sarcosaphagous flies species identification. Methods 30 sarcosaphagous fly samples were indentified by morphological method which collected in different regions belonging to 2 families, 4 genera and 6 species. MtDNA was extracted for the PCR amplification reaction in COI gene. The PCR products were purified through agar gel electrophoresis and sequenced. Sequences of 498 bp in COI gene were disposed by multiple-alignment software of DNAMAN. Sequences divergence of 498 bp between and within species of COI gene were processed by software of MEGA. Results It was showed that there is a certain sequence differences between the 30 samples from 6 species. The intraspecific and interspecific divergence of sequence variation ranged from 0.1% to 1.6% and 2.2% to 11.2% respectively. All the species can be identified successfully by this method. Conclusion Species identification of sarcosaphagous flies can be conducted by sequence analysis and phylogenetic tree of COI gene. This method can be effectively used in fast and accurate identification in forensic entomology.

Objective To investigate the value of 99Tcm-methoxyisobutylisonitrile (MIBI) scintigraphy in assessing the preoperative chemotherapy response and multidrug resistance of osteosarcoma.Methods From January 2007 to October 2008, 12 patients (female:4, male:8; mean age:16.3 years,range:8-27 years) underwent early (10min) and delayed (120 min) 99Tcm-MIBI scintigraphy before and after preoperative chemotherapy.Seven cases had osteosarcoma at the distal femurs, 2 at the proximal tibias, 2 at the upper end of humerus and 1 at the fibula.The tumor-to-background ratio (T/B) and washout rate (WR) were calculated.Tumor necrosis was classified according to Huvos criterion after limb salvage surgery.Immunohistochemical staining for P-glycoprotein(gp) was examined.Spearman correlation analysis and t-test were performed.Results According to Huvos criterion, 7 patients were classified as good responders with more than 90% of tumor cell necrosis and 5 as poor responders with less than 90% of tumor cell necrosis.R value (ratio of early phase T/B after and before chemotherapy) was significantly lower in good responders than that in poor responders (0.473 ± 0.21 vs 0.998 ± 0.06, t= 5.342, P= 0.000 ).R value was significantly correlated with the degree of tumor cell necrosis ( rs=- 0.87, P= 0.000 ).WR was significantly higher in patients with positive P-gp expression than that in patients with negative P-gp expression ((38.36 ±18.64)% vs (6.40±5.87)%, t= -3.278, P=0.008).There was significant correlation between the WR and P-gp expression (rs = 0.91, P= 0.001 ).Conclusion 99Tcm-MIBI scintigraphy is a feasible non-invasive technique to assess the chemotherapy response and to detect P-gp expression of osteosarcoma.
