Objective To observe the clinical effect of small dose mifepristone combined with traditional Chinese medicine in the treatment of uterine gland disease.Methods 76 patients with uterine gland disease were selected,they were divided into the observation group(n =38) and control group(n =38) by using random number table method.The control group was treated with small dose of mifepristone,while the observation group was treated with small dose of mifepristone combined with traditional Chinese medicine.The clinical curative effects of the two groups were compared.Results After treatment,in the observation group,the pain degree of patients [(21.30 ± 6.70) points],influence activity level [(17.30 ± 12.00) points],activity loss [(1.80 ± 0.70) spots] and grades of dysmenorrheal [(0.60 ± 0.20) stages] were lower than those in the control group,the differences were statistically significant (t =5.645,7.023,4.932,3.994,all P ＜ 0.05).After treatment,in the observation group,the uterine volume [(56.20 ± 2.00) mm3],CA125 level [(32.10 ± 2.10) U/mL] were lower than those of the control group (t =4.024,4.413,all P ＜ 0.05).The incidence rate of adverse reaction of the observation group was 7.89％,which was significandy lower than that of the control group,the difference was statistically significant (x2 =14.757,P ＜ 0.05).The patients were followed up for 8 months,the recurrence rate of the observation group was 5.26％,which was lower than 26.32％ of the control group,the difference was statistically significant (x2 =16.678,P =0.000).The menstrual recovery ratio less than or equal to three months of the control group was 81.58％,which was signifi candy higher than 63.16％ of the control group,the difference was statistically significant (x2 =8.484,P =0.003).Conclusion In the treatment process of adenomyosis,the small dose of mifepristone combined with traditional Chinese medicine can alleviate the clinical symptoms,reduce the pain and reduce the volume of uterus,and it has less adverse reaction,safe and reliable,it is worth of clinical application.

Objective To study the imaging characters and diagnostic value of spondylolysis and spondylolisthesis by usingthree-dimensional reconstruction of spiral CT. Methods 37 patients with spondylolysis were scanned by spiral CT.Various reconstruction methods were applied on the data acquired. Results The axial CT scans achieved good resolution on showing hyperostosis,fibrous callus and pathological changes of spinal disc.Spondylolysis was all displayed in the MPR/MIP of sagittal,reverse gantry angle and CPR.MIP,MPRand CPR could provide better resolution in display of spondylolysis than SSD did,while SSD was better in display of hyperostosis andspondylolisthesis. Conclusion The three-dimensional reconstruction of spiral CT is a good method for the radiographic evaluation ofspondylolysis and its relative changes.This technique can provide reliable informations for planning clinical therapy.

Objective To explore the technique of double spiral CT cerebral angiography in order to improve the quality of CTA.Methods All 62 cases underwent cerebral CTA,including vascular lesions in 30,normal in 20 and others in 12.All were scanned with GE Hispeed NX/I CT,three-dimensional models were used in images reconstruction.Results The branches of 1~4 grades of cerebral arteriae could be displayed well in all cases,some cases could also be visible up to 5th grades.All cerebral vascular lesions could be showed by CTA and the same as DSA.Cerebral tumor could be demonstrated with tumor stain.The image quality would be better when the pitch was smaller with the same layer.Conclusion The factors that influence on the quality of CTA images are a lot of,but mostly are concerned with the pitch,contrast volume,injection rate and delayed time.

Nephrocalcinosis is often accompanied by kidney stone disease. In recent years, more and more nephrocalcinosis has been found to be caused by a monogenic disease, and its pathogenesis has not been fully elucidated. With the development of molecular genetics, more than 30 genes have been found to be the causative genes of nephrocalcinosis. At the same time, with the widespread development of genetic testing technology, more patients have received early diagnosis and timely intervention. This article reviews the clinical and basic research progress of monogenic nephrocalcinosis.

Objective To investigate the X-ray,CT and MRI features of peripheral primitive neuroectodermal tumors (pPNETs).Methods 14 patients were pathologically diagnosed with pPNETs.The imaging of X-ray (twelve image),Computed Tomography(eleven image) and Magnetic Resonance Imaging(five image) were retrospectively analyzed.Results Of 14 patients,there were two sites of tumour:soft tissue( eight patients) and bones( six patients).For tumoura of the soft tissue region,the appearance of X-ray and CT imaging showed equal or lower density soft mass without dear boundary.In some cases,tumours invaded adjacent bones.The appearance of MRI imaging showed large heterogeneous masses inside soft tissue without clear boundary.Tumours displaced adjacent cortical bone and cavitas medullaris.All masses were heterogeneous enhancement on contrast images.For tumours of bone region,X-ray and CT scan showed large scale osteolysis osteoclasia in bone surrounding with soft tissue masses of various size.The lesions were equal or lower signal on T1 WI.All masses were intermediate or hyperintense signal with heterogeneous midrange or obvious enhancement on T2WI.Conclusion Imaging characteristics of pPNETs were described.X-ray,CT and MRI were useful in understanding the property,extent and staging of tumor and very useful in the diagnosis.

Objective To explore how Vibrio vulnificus (Vv) invades dendritic cells (DC) and induces acute necrosis of DC via toll-like receptor (TLR) 2 and 4 pathways.Methods Vv 1.1758 strain and DC 2.4 mixed culture model was established,observed the infection rates of DC with optical microscope,the location of Vv and structural changes of DC by transmission electron microscope.The expression levels of TLR2 and TLR4 mRNA were determined by real-time quantitative reverse transcription polymerase chain reaction (RT-qPCR) and tumor necrosis factor-α (TNFα) protein titers were measured by enzyme-linked immunosorbent assay (ELISA).DNA ladder qualitative test was used to detect cell apoptosis,while flow cytometry was used to quantify cell apoptosis and necrosis rates.Statistical analysis was done by chi-square test and one-way ANOVE.Results The infection rates of DC after 0.5,1,2,4 and 6 h of mixed culture were (7.8±0.8) ％,(13.9± 1.1) ％,(34.6±4.9) ％,(77.8± 10.2)％ and (95.8 ± 13.1)％,respectively.Vv was generally located in the internal cell membrane of DC 2.4.After 2 h co-culture,nuclear chromatins of DC became active and intranuclear apoptosis bodies appeared.After 4 h,cytoplasmic vacuoles appeared,chromatin gathered,and cell membranes were seriously damaged.After 6 h,mitochondria was highly swelled and distorted,and cell apoptosis and necrosis occurred.TLR2 and TLR4 mRNA levels reached peak values after co-culture for 0.5 h; TNF-α level began to increase at 1 h (P＜0.05) and reached peak values at 2 h.DNA Ladder electrophoresis presented scouring necrosis after 2 h culture and apoptotic bands appeared between 720 bp and 900 bp after 4 to 5 h culture.Early apoptosis rates of DC after 2,4 and 6 h culture were (3.1±3.8)％,(7.8±4.7)％ and (12.7±8.2)％,and necrosis rates of DC were (16.7±12.5)％,(41.6±25.9)％ and (75.5±33.6)％,higher than that of control group (all P＜0.05).Conclusions Vv infects DC and induce DNA degradation through up-regulated expression of TLR2 and TLR4 and increasing of TNF-α inflammatory mediators.During cell degradation,apoptosis and necrosis coexist,while necrosis is predominant.

Primary hyperoxaluria (PH) are important causes of kidney stone and chronic kidney stone disease in children. Recurrent kidney stone disease and nephrocalcinosis should alter the physician to the possibility of an inborn error of metabolism as the underlying cause. Unfortunately, the lack of recognition of genotype and phenotype of PH resulted in an unacceptable delay in diagnosis and treatment, sometimes with grave consequences. This paper review the characteristics of genotype and phenotype, genotype-phenotype correlation, current treatment and future gene therapy of PH.

OBJECTIVE: To evaluate the clinical outcomes of single-balloon kyphoplasty in the treatment of thoracic osteoporotic compression fractures via extrapedicular approach METHODS: From July 2004 to May 2008, 38 cases (52 vertebra) of thoracic osteoporotic fractures were treated by balloon kyphoplasty via unilateral extrapedicular approach, including 12 males and 26 females with an average age of 60.3 years (range 55-72 years). There were 34 cases of primary osteoporosis, and 4 had administrated hormone due to other diseases for over 6 months. Symptomatic levels ranged from T_4 to T_(12) confirmed by physical examination, MRI and X-ray. The pain relief, restoration of vertebral height and kyphosis correction were compared before and after operation by using visual analogue scale (VAS) and radiograph, respectively. In addition, bone cement leakage location and complications were recorded. RESULTS: Operation were successfully performed in 38 cases with an average injection of bone cement volume of (3.2+ 1.4) mL (2.25-4.60 mL in unilateral infusion). The mean time of surgery was 25-55 minutes, and that of follow-up was 9.5 months (6-24 months). Back pain of 36 cases was improved, and the VAS 3 days postoperatively and the final follow-up was significantly reduced (P < 0.05). The vertebral anterior margin and median height following surgery were significantly improved detected by X-ray (P < 0.05), and average median height restoration was (50.90+34.60)%, but no significant change was found in posterior height (P > 0.05). No lateral wedging or changes in the coronal alignment was found. Three cases (5 vertebra) had cement leakage: the bone cement of 1 case leaked to posterior margin through the puncture channel, and 2 cases leaked to lateral vertebra through vertebral venous system without any adverse event. The patients could move the second day after surgery, discharged from the hospital at days 3-4, and restored to normal life at 1 month postoperatively. No blood vessel or spinal cord puncture injury or pulmonary embolism, or blood vessel embolism was found. CONCLUSION: Unilateral extrapedicular kyphoplasty is safe and effective in treating thoracic osteoporotic fractures. It rapidly releases backache, restores the body height of fractured thoracic vertebrae and improves quality of life of the patients.
