Objective To improve the diagnosis and treatment of xanthogranulomatous pyelonephri- tis(XGP).Methods The clinical data of 18 cases(5 males and 13 females;mean age,47 years)with XGP were analyzed.Of them,6 had the lesion on the left,and 12 on the right.Before operation,XGP was mis- diagnosed as renal calculus with hydronephrosis in 4 cases,ureteral calculus with severe hydronephrosis in 3 cases,renal tuberculosis in 3 cases and renal carcinoma in 8 cases.Results Of the 18 cases,7 were diag- nosed to have XGP by frozen section during operation and 11 cases had a definite diagnosis by pathological examination after nephrectomy.After a follow-up of 6-124 months,no recurrence was observed in all these 18 cases.Conclusions Preoperative diagnosis of XGP is difficult.This disease is clinically characterized by foam cells in urine smear,low-density value of kidney CT and ineffective antibiotic therapy.Combined a- nalysis of clinical data and improvement of clinical recognition of XGP is the key to avoiding delayed diagno- sis or misdiagnosis of XGP.

This article aimed to study the antigenicity of nucleocapsid proteins (NPs) in six pathogenic phleboviruses and to provide theoretical evidence for the development of serological diagnostic reagents. NPs of six pathogenic phleboviruses were expressed and purified using a prokaryotic expression system and rabbits were immunized with individual recombinant NPs. Cross-reactions among NPs and rabbit sera were determined by both indirect ELISA and Western blotting analyses, and the sera titer was determined by indirect ELISA. Furthermore, sera from SFTS patients were also detected by each recombinant NP as a coating antigen using indirect ELISA. The cross-reactions and the sera titer were subsequently determined. Both the concentration and purity of recombinant NPs of six pathogenic phleboviruses met the standards for immunization and detection. The results of indirect ELISA and Western blotting showed that each anti-phlebovirus NP rabbit immune serum had potential serological cross-reactivity with the other five virus NP antigens. Furthermore, the sera from SFTS patients also had cross-reactivity with the other five NP antigens to a certain extent. Our preliminary study evaluated the antigenicity and immune reactivity of six pathogenic phleboviruses NPs and laid the foundation for the development of diagnostic reagents.

OBJECTIVETo evaluate the clinical outcomes of percutaneous intervertebral foramina endoscopic lumbar discectomy for elder patients with lumbar spinal stenosis syndrome.
METHODSFrom July 2006 to July 2011, 60 elder patients with lumbar spinal stenosis syndrome were treated with surgical operation, including 32 males and 28 females with an average age of (66.7 +/- 2.5) years old ranging from 72 to 83 years. These patients were divided into the traditional surgery group and percutaneous intervertebral foramina endoscopic discectomy groups (PTED group), 30 cases in each group. The index of the preoperative and postoperative, operative incision visual analogue scale (VAS) of two groups were compared. The Oswestry disability index (ODI) of two groups at 6, 24 months of the follow-up were also evaluated on activity of daily living.
RESULTSThe average operative time, the average blood loss, the number of cases using analgesic drug, hospitalization time of PTED group were better than those of the traditional surgery group (P < 0.05). The improvement of incision VAS in PTED group was better than that in the traditional surgery group (P < 0.05). All patients were followed up for 24 months at least. The ODI at 1, 24 month after operation were better than that of preoperative in two group respectively (P < 0.05), but the improvement of PTED group was better than that of the traditional surgery group (P < 0.05).
CONCLUSIONPTED has the advantages of smaller incision, less bleeding, less postoperative stay and hospitalization time, tissue trauma and quicker recovery. It is a safe and efficacious minimally invasive surgical technique for elder patients with lumbar spinal stenosis syndrome.

The UHPLC-LTQ-Orbitrap high resolution mass spectrometer was used to explore the chemical compositions in safflower. The rapid separation of the compositions was conducted by the UHPLC, following by high resolution full scan and MS2 scan, under the positive and negative ion mode. The chemical formula of compositions were deduced by full scan data in less than 5, then the potential structures were confirmed by the MS2 data. Forty-nine compounds were detected, of which 26 was identified, and 5 compounds was validated by the standard substances.

Objective To explore the effects of overexpression of hypoxia inducible factor 1? (HIF 1?) mRNA on vascular endothelial growth factor (VEGF) and novoendotheliasis in venous autografts Methods Wistar rats were randomly divided into two groups with 28 rats in each group A rat experimental model of autogenous vein graft was established by transplanting the right external jugular vein into between the interrupted right common carotid artery The transplanted vein in the experimental group was first immersed into a solution containing recombinant adeno associated virus (rAAV) HIF 1? for 45 minutes Vein grafts and blood simples were taken at 7 or 14 days after transplantation RT PCR, ELISA, immunohistochemistry were used to detected HIF 1? mRNA and VEGF expression Results HIF 1? mRNA and VEGF protein remarkably increased in experimental group, and serum level of E selectin significantly decraesed at day 14 The novoendotheliasis and myo endothelium junction in vein grafts were remodeled at day 14 in the experimental group Conclusion Re establishment of the structure and function of the autograft vein graft endothelium was accelerated by overexpressed HIF 1? mRNA
