Objective　To investigate the importance of CT diagnosis and differential diagnosis in Wilms′ tumors of children.Methods　45 cases of Wilms′ tumors confirmed by clinical and pathology were retrospectively analyzed,CT characteristics of Wilms′ tumor,renal carcinoma(2 cases),renal rhabdomyosarcoma(1 case)in children were discussed.Results　Wilms' tumors appeared in solid masses in 34 cases (76%),cysticsolid masses in 9 cases(20%),cystic masses in 2 cases (4%),7 cases (15.6%)had thrombosis in renal vein or IVC.Renal carcinoma shared the same appearance with Wilms′ tumor in image.Rhabdoid tumor of kidney appeard as cystic-solid mass with lineal calcification and subcapsular fluid accumulation.Conclusion　Wilms′ tumor is the most popular malignant renal tumors in children.It is originate from renal parenchyma,and likely to invade renal pelvis.Hemorrhhage,necrosis or cystic formation in tumor is common.They are difficult to be distinguished from renal cell carcinomas in radiology.Rhabdoid tumor of kidney is rare and has characteristic features on CT.

Objective To analyze the causes for diffuse bone marrow uptake of 18F-FDG on PET/CT scans. Methods Sixty-six patients with diffuse bone marrow uptake on whole-body FDG-PET/CT imaging were enrolled for this study. Seventy-nine healthy subjects ( with no history of tumor or recent fever) were selected as normal control. The SUVmax and SUVmean were measured in bone marrow and mediastinum in both groups. The maximum (bone marrow SUVmax/ mediastinum SUVmax) and mean value ratios (bone marrow SUVmean/ mediastinum SUVmean) were calculated. Statistical analysis was performed by one-factor variance analysis. Results With diffuse bone marrow uptake pattern of 18F-FDG, 27 were caused by injection of hematopoietic growth factor, 21 by hematopathy and 18 due to fever. SUVmeanof those three causes were 3.076±1.955, 3.633±2.405 and 2.546±0.791 respectively, each was significantly different from that of the control group (1.026±0.190; F =34.465, P<0.001). Conclusion Diffuse bone marrow uptake on FDG-PET/CT are caused by both benign and malignant reasons.

Objective:To analyze the correlation between preoperative parametres and positive surgical margin after robot-assisted laparoscopic radical prostatectomy.Method:From October 2014 to January 2019, the clinical data of 310 patients who underwent robot-assisted laparoscopic radical prostatectomy(RARP) by single surgeon were collected retrospectively. The median age, PSA, f/t PSA and PSAD was 68(62-72)years, 26(13-63) ng/ ml, 0.12 (0.07-0.18) and 0.36(0.20-0.75) ng/ml 2, respectively. There were 115 cases with clinical T 1, 100 with clinical T 2, 41 with clinical T 3, and 15 with clinical T 4. Based on the MRI or ultrasound examination, the median value for the transverse diameter, anteroposterior diameter, vertical diameter, and volume of the prostate is 44(35-50)mm, 45(40-51)mm, 41(36-50)mm, and 76(54-118)ml, respectively. In this study, 84(27%)cases were diagnosed pathologically by transurethral resection of the prostate, and 226(73%)cases by prostate biopsy. The biopsy technique was transrectal ultrasound-guided systematic 12-point biopsy, and additional 1-5 needles were performed in regions with abnormal ultrasound echoes. The median for total number of puncture needles, number and percentages of positive needles were 12(12-13), 9(4-12)and 85%(35%-100%), respectively. Of all the patients, there were 61 cases with Gleason score≤6, 95 with Gleason score=7 and 84 with Gleason score≥8. There were 237(76%)patients undergoing neoadjuvant endocrine therapy. The patients were divided into the negative surgical margin group and positive surgical margin group. The correlation between positive surgical margin and general clinical data, PSA derivates, prostate size (transversal diameter, anteroposterior diameter, vertical diameter, and prostate volume), percentage of positive biopsy cores, Gleason score, method of pathological diagnosis, and endocrine therapy were analyzed. Results:Of all the 310 enrolled patients, the overall positive surgical margin rate was 34.2%(106/310). Univariate analysis showed that tPSA(41.3 ng/ml vs.24.8ng/ml, P=0.029), f/tPSA(0.14 vs.0.10, P=0.004), transversal diameter of prostate(46 mm vs.38mm, P=0.049), percentage of positive biopsy cores(100% vs.58%, P=0.001), and biopsy Gleason score(Gleason score≤6, =7 and ≥8: 14, 31 and 32 cases vs. 47, 64 and 42 cases, P<0.05)exhibited significant correlation with postoperative positive surgical margin. Multivariate analysis showed that transversal diameter of prostate( P=0.026) and percentage of positive biopsy cores( P=0.048) were independent risk factors for positive surgical margin. Conclusions:Transversal diameter of prostate and percentage of positive biopsy cores were independent risk factors, which help to predict the occurrence of postoperative positive surgical margin.

Oroxylum indicum was a traditional Chinese medicine. In order to study the chemical constituents from the seed of O. indicum, the chemical constituents of 80% methanol extract of seeds of O. indicum were subjected to chromatography on silica gel, Sephadex LH-20, and preparative HPLC, leading to the isolation of eleven compounds. The structures were identified by various spectroscopic data including ESI-MS, 1H-NMR and 13C-NMR data as oroxin B (1), chrysin (2), baicalein (3), neglectein (4), quercetin-3-O-β-D-galactopy ranoside (5), quercetin-7-O-β-D-glucopyranoside (6), 2α,3β-dihydroxylluPeol (7), lupeol (8), rengyol (9), β-sitostero (10), and stigmasterol (11).

Objective To find out prevelence of thyroid goiter on school-aged children in excessive iodine region of Shandong Province.Methods By employing B-ultrasonography and palpation method,the thyroid volume were investigated and the thyroid goiter rate were calculated among 6415 children aged 8～10 years old in execssire iodine region.Results By employing B-ultrasonography method.The volumes of thyroid in goiter children aged 8,9,10 years were(5.67±1.49),(6.07±1.24),(7.30±2.01)ml,respectively.The goiter rates were 28.84%(683/2368),20.89%(448/2144),11.82%(225/1903).The volumes of thyroid in non-goiter children aged 8,9,10 years were(3.36±0.67),(3.64±0.77),(4.02±0.94)ml.When the normal value of thyroid volume in 8 and 9 year-groups lowered 0.5 ml,the goiter rate would be changed to 18.20%(430/2368)and 12.92%(277/2144) respectively.The thyroid volumes of boys and girls were(4.20±1.38),(4.18±1.73)ml,respectively.The goiter rates of boys and girls were 21.92%(732/3340)and 20.29%(624/3075)respectively.The rates of goiter detected by palpation in 8,9 and 10 year-groups were 10.05%(238/2368),10.31%(221/2144)and 14.45%(275/1903) respectively.Conclusions Along with the increasing age,the volume of thyroid in children aged 8～10 is increasing in excessive iodine region of Shandong Province.But the goiter rate is decreasing ahmg the increasing age.This phenomena may be caused by improper normal value of thyroid volume.Therefore,the normal value of thyroid volume should be revised urgently.

OBJECTIVETo study the role of trisomy 8 in pathogenesis and progression of hematologic disease with trisomy 8.

METHODSThe clinical data on 38 cases with trisomy 8 were investigated retrospectively. Fluorescence in situ hybridization (FISH) using Spectrum Orange labeled chromosome 8 centromere specific probe was carried out to detect trisomy 8 in 10 cases.

RESULTSThirty-two of 38(84.2%) cases with trisomy 8, and fourteen of 17(82.4%) cases with trisomy 8 as the sole chromosome aberration were myeloid disorders such as myelodysplastic syndrome (MDS), acute myelocytic leukemia (AML), chronic myelocytic leukemia (CML). The incidence of trisomy 8 was higher in myeloid disease than in lymphocytic disease (5% vs 1.3%); the incidence of trisomy 8 was higher in acute monocytic leukemia than in other AML (6.1% vs 2.4%), and the incidence of trisomy 8 in chronic myelomonocytic leukemia( CMML) was higher than that in other myelodysplastic syndrome (MDS) (25% vs 13.2%); 17 cases had trisomy 8 as the sole chromosome aberration, 21 cases had other additional chromosome aberrations. The chromosome aberration was confirmed by FISH in 10 cases with trisomy 8 as the sole chromosome aberration. Eleven cases were treated with chemotherapy, among them only 10 cases data were available. Seven cases acquired complete remission but 3 of them were M3, the other 3 cases had no response after two courses of chemotherapy.

CONCLUSIONTrisomy 8 may play an important role in the pathogenesis and progression of the hematological disease, especially myeloid disease. Trisomy 8 might be related with differentiation abnormality of monocyte.

The purpose of this study was to investigate 135 cases of chronic myelogenous leukemia with non-simple Philadelphia chromosome and to analyze their cytogenetic date. Chromosome preparations in 135 cases of patients were performed by using direct method and/or short-term culture, and karyotyping was performed with R-banding technique. The results showed that the overall frequency of chronic myelogenous leukemia with non-simple Philadelphia chromosome (based on 1210 cases of chromosome detection in chronic myelogenous leukemia) was 11.16%, which included 87 cases of chronic phase, 21 cases of accelerated phase and 27 cases of blastic phase. Among 87 cases of patients in chronic phase, 14 cases were with simple variant translocation and 22 cases had complex variant translocation while the others were with other chromosomal abnormalities including 4 cases of +8, 4 cases of + Ph and 2 cases of i (17); among 21 cases of patients in accelerated phage, 4 cases were with +8 and 4 cases were with + Ph while 3 cases were with i (17); among 27 cases of patients in blastic phage, 2 cases were with simple variant translocation and 3 cases had complex variant translocation while the others were with other chromosomal abnormalities including 5 cases of +8, 5 cases of + Ph and 2 cases of i (17). The detection rate of extra chromosomal abnormalities in this group of 135 cases patient were + Ph, +8, i (17), -Y, +19 and +21 in order. There were 16 cases with simple variant translocation and 25 cases with complex variant translocation in in this group of 135 cases. It is concluded that karyotype analysis is helpful in diagnosis, prognosis, pathogenesis and treatment selection for chronic myelogenous leukemia.

OBJECTIVETo investigate the morphologic changes of upper airway in obstructive sleep apnea and hypopnea syndrome (OSAHS) associated with micrognathism before and after orthognathic surgery and distraction osteogenesis, and subsequently to instruct clinical jobs effectively.

METHODSNine OSAHS patients associated with micrognathism (8 males, 1 female, mean age: 28.6 years) received orthognathic surgery and (or) distraction osteogenesis, and the curative effect was evaluated according to the subjective feelings and PSG. Upper airway structure before and after the treatment was measured by Somatom Sensation 16 CT scanner.

RESULTSAll 9 patients were clinically cured. The transverse length, the cross section area, and especially the sagittal length of the upper airway were obviously increased after the orthognathic surgery. The changes involved mainly in the velopharyngeal region and the laryngopharyngeal region, but not in the laryngopharyngeal region.

CONCLUSIONSThe orthognathic surgery and distraction osteogenesis can treat the OSAHS patients with microgonathism effectively by increasing their velopharyngeal and laryngopharyngeal sagittal length of upper airway.

BACKGROUNDPhotodynamic therapy (PDT) with 5-aminolevulinic acid (ALA) is an emerging technique for the treatment of genital human papillomavirus (HPV)-induced benign and premalignant lesions. We report here in a case series of condyloma acuminata (CA) in pregnancy successfully treated with ALA-PDT.

METHODSFive pregnant patients with CA received three to four times treatment respectively. Patients were followed up for 6 - 23 months after treatment.

RESULTSThe clearance rate of genital warts was 100%. No recurrence was found during the follow-up period. Major adverse events reported were mild erosion, pain, and local edema. All pregnancies resulted in healthy live births without delivery complications.

CONCLUSIONSPDT with topical ALA seems to be safe and effective in the treatment of CA in pregnancy. It demonstrated high clearance rate of warts, was well-tolerated by patients, and showed no adverse effects on mothers or fetuses. ALA-PDT may be an ideal strategy of treatment for pregnant women with CA.
