Objective To understand the effect of vanadium to liver ultramicro structure in SD rats.Methods One hundred and fifty generaMevel SD rats of 2 months were randomly divided into control groups,30 in each,the males and females were equivalent,treated with ammonium metavanadate at doses of 0,10,20,40,60 mg/L through drinking water.After 2,6 and 10 weeks of treatment,6 rats from each group were weighed and the changes of ultramicro-structure in the liver were examined with electron microscope.Results As the increasing of dose,the increase in body weight showed a downward trend,but the coefficient of liver showed a increasing trend,the consistent performance was seen in male and female rat.After two weeks of exposure,the rats acted,ate and drank less,hair roughing and no shining,often getting together were seen.After 10 weeks,the rats had not the basic activities,the hair was disheveled and loose,some died,the structure of mitochondria and endoplasmic reticulum was normal in the 10,20,40 mg/L group,the number of endoplasmic reticulum increased,in 60 mg/L group,the rough endoplasmic reticulum vanished,the liver cytoplasm had a swelling phenomenon,the mitochondria reduced.Conclusion Vanadium have little effect on the liver cells of rats in low exposure level,but high level exposure may damage the liver cells in rats.

Age-related macular degeneration ( AMD ) is a kind of age-related blinding degenerative fundus lesions, totally about 30 million patients suffering from AMD all over the world, with about 500 000 people blind for it yearly. As the development of economy and the aging of the population intensified, incidence of AMD indicates a trend of rising year by year, being the third major cause of blindness in our country. At present, the pathogenesis of AMD is not fully clear, as reported it may be related to oxidative stress, inflammatory immune response, VEGF and genetic manipulation. Clinical treatments mainly include photodynamic therapy, drug therapy, radiation therapy, laser photocoagulaory operation, the pupil warm treatments, Chinese medicine and intravitreous injection VEGF antagonists such as Ranibizumab, Conbercept and so on. ln this issue, we mainly expound on the progress in the epidemiological studies of AMD, especially elaborate the progress made on genetic manipulation in recent years.

Objective To study the preliminary effect of sartorius iliac flap in repair of acetabulum defect for developmental dysplasia of the hip (DDH) in elder children.Methods We retrospectively studied 17 elder children with acetabulum defect in DDH at the age＞6 years old who received acetabular repair with sartorius bone flap in this hospital from 2014 to 2016.All patients with acetabulum defect in DDH were treated with open reduction in general anesthesia.Three-dimensional osteotomy under the femur rotor was conducted to correct the femoral anteversion and neck-shaft angle.According to the height of femoral head dislocation lines,femur tuberosity was shorten and fixied with steel plates,joint capsule was reconstructed,The iliac sartorius musculocutaneous flap was took to the upper edge of the acetabular to repair the acetabular defect.The lower extremities were treated with plaster for 6 to 8 weeks after surgery.The hip joint function was trained and the function was evaluated with Mckay's criteria.The hip joint morphological evaluation was performed with reference to Severin's X-ray standard.Results Seventeen patients were followed up for 6 to 29 months.Postoperative reduction of the femoral head was good,the head mortar inclusive was satisfactory;there were no wound infection and femoral head necrosis.According to Mckay's criteria,2 patients got excellent,13 good,and 2 fair,with the fineness ratio at 88.2％;According to Severin's critera:11 patients excellent.Conclusion The overturned sartorius iliac flap can repair acetabulum defect,promote bone healing,and effectively improve acetabulum to cover head of femur.

Objective To study the clinicopathologic characteristics of sarcomatoid carcinoma of the lung.Methods Clinicopathologic characteristics and immunohistochemical results of 42 cases with sarcoma- toid carcinoma of the lung were analyzed.Results Forty-two cases were pathologically proved to be spindle cell carcinoma,1 cases;giant cell carcinoma,1 case;carcinosarcoma,4 cases;pleomorphic carcinoma,36 cases.The tumors were composed of both carcinomatous and sarcomatous elements.Immunohistochemistry showed that CK was positive in 24 of 24 cases,EMA was positive in 18 of 20 cases,Vim was positive in 25 of 25 cases.Eighteen cases were survival One-year survival rate was 61.2 %,with mean survival 13.3 months. Conclusion Diagnosis of sarcomatoid carcinoma of the lung depends on pathologic and immunohistochemical results.

On the basis of the Uncaria transcriptome, specific primers were designed for UrSTR. The full-length cDNA of UrSTR (GeneBank: OL310251) was 1 541 bp, encoding 345 amino acid residues, and the promoter region sequence of UrSTR (GeneBank: OL310252) was 1 179 bp. Phylogenetic tree is revealed that UrSTR had a closest relationship with STR from Ophiorrhiza pumila and Ophiorrhiza japonica. Localization of UrSTR protein is revealed located in the vacuole membrane. Plant-care analysis indicated that the promoter region sequence of UrSTR, covering multiple light, stress and hormone-response cis-regulatory elements, and verified transcriptional activity. The results of SDS-PAGE show that pET-28a-UrSTR recombinant protein was successfully expressed, and the size was anticipated. The UrSTR prokaryotic expression system needs to be optimized in the later stage. The research lays the foundation for further purification to study its structure and functional characterization of the UrSTR protein.

Objective To investigate the clinical outcome and prenatal diagnosis feasibility of fetal congenital cardiac diventiculum.Methods The data of 12 fetuses with congenital cardiac diventiculum were retrospectively reviewed.The prenatal and postnatal medical records,including the characteristics of diverticulum,presence of abnormalities,karyotype and the outcomes of each pregnancy were collected.Results The overall incidence of cardiac diventiculum was 0.03％ (12/40 564) and the rate of incidence between left and right ventricle was 2 ∶ 1.Mean size of diventiculum was (69.75 ± 28.73)mm2,mean diameter of the diventiculum neck was (3.58 ± 0.80) mm and mean thickness of diventiculum wall was (1.54± 0.29)mm.Seven cases (58.4％) as an isolated malformation,5 cases (41.6％) combined with cardiac defect and extracardiac abnormalities,2 cases (16.7 ％) with chromosomal abnormalities.Five cases underwent termination of pregnancy,1 case died in uterus and 6 cases were born live.The mean follow-up periods was (62.33±-36.52)month.Of the 6 follow-up cases,4 cases (66.7％) remained asymptomatic,one case underwent drug therapy because of arrhythmia and one case combined with VSD underwent operation.Conclusions Echocardiography could be an useful tool to demonstrate and monitor congenital cardiac diventiculum prenatally and postnatally.The outcome of cardiac diventiculum depends on the size,progression,and the combined abnormalities and complications.

Chlorogenic acid displays several important roles in the therapeutic properties of many herbs, such as antioxidant activity, antibacterial, antiviral, scavenging free radicals and exciting central nervous system. Only about one-third of chlorogenic acid was absorbed in its prototype, therefore, its gut metabolites play a more important role in the therapeutic properties of chlorogenic acid. It is necessary to consider not only the bioactivities of chlorogenic acid but also its gut metabolites. This review focuses on the potential activities and mechanisms of chlorogenic acid and its gut metabolites on central nervous system diseases.

A total of 1 100 patients underwent renal transplantation in the Organ Transplantation Center,Second Affiliated Department of General Hospital of Chinese PLA between 1988 and 2008 were collected,and retrospective analysis was performed in five female patients with malignant tumor,which appeared at 68 months (20-132 months) following renal transplantation,including 2 with renipelvic and uretal cancer and 3 with bladder cancer. Two of the 3 patients with bladder cancer presented homolateral renipelvic and uretal metastasis. Three cases and 1 case of upper uretal cacer were observed at the homolateral or heterolateral of kidney grafts respectively. The main characteristic of sign was iterative and painless gross hematuria. The 5 patients underwent renal transplantation with intravesical instillation therapy and nephrectomy. All patients were survived without rejection in the 1-62 months follow-up. The incidence of malignancy in renal allograft recipients is much higher than that in normal ones,which is related to the long term use of immunosuppressants. Urinary epithelial cancer is the main complicating carcinoma and the first choice of treatment is surgical operation. Based on the normal renal grafts function,the dose of immunosuppressants should be as low as possible,Moreover,radiotherapy or chemiotherapy should be adopted according to the types and stages of tumor complicating renal transplantation.

Objective To analyze the pathological and clinical characteristics of patients with idiopathic IgA nephropathy accompanied by vasculitic/crescentic lesion (IgA-V/C). Methods Data of 222 patients diagnosed as idiopathic IgA nephropathy by renal biopsy, among them 87 cases with vasculitic/crescenlic (V/C)lesion, from our department in 2004 were analyzed retrospectively. Clinical and pathological data from patients with IgA-V/C were compared to those of non-IgA-V/C patients and of lupus nephritis (LN) patients with V/C lesion. Results Vasculitic/crescentic lesion was found in 39.19% (87/222) patients with idiopathic IgA nephropathy.And about( 14.08?12.75)% of the glomeruli was affected. It should be taken into account that there was no significant differences of clinical manifestations including blood pressure, urinary protein excretion between IgA-V/C group and non-IgA-V/C group .except serum creatinine(Scr)level which was significantly higher in IgA-V/C group. In addition, only 37.9% of IgA-V/C patients presented high Scr level,thus the lesion of V/C in idiopathic IgA nephropathy was easily overlooked. Patients with idiopathic IgA nephropathy were found to have higher percentage of glomerular sclerosis (64.86% vs 40.00%) and ratio of sclerostic glomeruli to total glomeruli [ (26.98 ?24.68)% vs (16.10 ?18.80)% ]as compared to LN group, which further predicated the progressing characteristics of IgA nephropathy. Conclusions Vasculitic/crescentic lesion is a quite common finding in idiopathic IgA nephropathy and often associated with no dramatically symptoms. It is possible for vasculitic/crescentic lesion to induce unmarked lose of nephron slowly and continually, so as to accelerate IgA nephropathy progression to end-stage renal failure.
