Objective To explore the mechanism of tripterygium wilfordii hook f(TWHF)for Henoch-Schonlein purpura nephritis(HSPN,nephrotic type)in children.Methods All the children with HSPN(nephrotic type)were divided into 3 groups casually.Method of radioactive pairs conjugating analysis was used to determine the numbers of glucocorticoid(GC)receptors(GCRs).Results were statistically analysed respectively.Results GCRs tested in all the patients with HSPN(nephrotic type)before treatment were statistically lower than those in control group of normal children;GCRs in all the patients tested after 1 week treatment with GC were lower than before treatment.Three weeks later,GCRs in patients treated with TWHF increased much higher than them without TWHF.Following up the recurring times of all the patients 3 months to 5 years,they were much more in patients treated without TWHF treatment than in patients treated with it.Conclusions TWHF treatment on HSPN(nephrotic type)is obviously effective.It can not only decrease the dosage of GC,but decrease the recurring times.One of the mechanism may be TWHF can resist the down-regulation GC to GCR,and enhance the effect of GC.

Objective To evaluate MSCT appearance and impaction of Ⅴ, Ⅷ segments' hepatic venous congestion ( HVC ) on hepatic functional recovery in living donor liver transplantation (LDLT).Methods In this study, 83 patients undergoing LDLT in our hospital were included, all subjects received plain and contrast MSCT examinations at early stage (within 1 month) and later stage (3 months later) after LDLT. MSCT appearance of HVC was recorded, at the same time, gutamic pyruvic transaminase ( ALT),glutamic oxalacetic transaminase (AST), total bilirubin (TB) and prothrombin time (PT) of 1 to 7 days after LDLT between congestion group and non-congestion group were recorded and compared.Results Segments Ⅴ and Ⅷ congestion was identified by after LDLT CT scanning in 20 patients (24. 10% ). Congestion volume and congestion ratio was (218. 25 ± 130. 29) cm3 and 16. 68% ±8. 81%,respectively. HVC often appear as hypoattenuation on plain CT scan and arterial phase, mixed or hyperattenuation on portal vein phase. There was no significant difference of ALT, AST, TB and PT after LDLT between congestion group and non-congestion group (P ＞ 0. 05). Conclusions MSCT is a valuable method to evaluate Ⅴ, Ⅷ segments' HVC after LDLT, most HVC has no impaction on hepatic functional recovery in LDLT patients.

Objective To investigate the safety and clinical significance in presurgical application of tyrosine kinase inhibitor (TKI) targeted therapy in high-risk renal-cell-carcinoma patients.Methods TKI targeted therapy was applied to 33 high-risk renal-cell-carcinoma patients from Jun.2010 to Dec.2013,7 cases with paraneoplastic symdromes and 1 with bilateral lesions received surgical treatments.There were 6 males and 2 females in this group with average age of 50 (42-56) years.They were high-risk patients because of renal tumor and vena caval tumor thrombus in 3 cases,renal tumor and vena caval tumor thrombus and hypercalcinemia in 1 case,renal tumors with metastasis to lung and lymph nodes in 2 cases,renal tumor with metastasis to lung and bones in 1 cases,and bilateral kidney cancer in 1 case.The clinical stages included 3 cases of T3aN1M1 and T3bN0M0 respectively,and 1 case of T3bN0M1 and T3aN0M0,respectively.The primary metastasis sites were lymph nodes and lung (3 cases respectively),and another 1 in bone.4 cases suffered from vena cava tumor thrombi with 3 staged Mayo Ⅲ and 1 Mayo Ⅳ.7 cases with paraneoplastic syndromes were contra-indicated for surgery due to poor ECOG performance score (with score 3 in 3 cases and 2 in 4 cases).4 cases received Sorafinib 400mg po bid and the other 4 Sunitinib 50 mg po qd,4 weeks on and 2 weeks off,with duration of 8-12 weeks.Medical therapy ceased 6 to 16 days (median 12 days) before operation.Results Patients with neoadjuvant therapy experienced good toleration.The 7 cases with poor ECOGs improved during medical therapy.The tumor sizes in the bilateral lesions shrunk remarkably.All 7 patients received surgery:3 radical nephrectomies,4 nephrectomies and resections of Vena Caval tumor thrombus,and 1 bilateral lesions underwent nephron sparing surgery.Operations were successful though with mild to moderate adhesion,and the blood loss ranged from 120 to 500 ml,with averaged of 280 ml.Pathologic results were clear-cell renal carcinomas.All incisions were well-healed.4 patients with metastasis continued TKI therapy.All patients were alive without recurrence during the follow-up of 4 to 42 mon.Conclusions Presurgical application of targeted therapy is safe and may increase the opportunity of surgery for some patients with poor general situation,also patients with bilateral lesions may benefit from it for its possibility of nephron sparing.

Ultrafine powder and cell wall-broken powder of herbal medicine lack of the morphological characters and microscopic identification features. This makes it hard to identify herb's authenticity with traditional methods. We tested ITS2 sequence as DNA barcode in identification of herbal medicine in ultrafine powder and cell wall-broken powder in this study. We extracted genomic DNAs of 93 samples of 31 representative herbal medicines (28 species), which include whole plant, roots and bulbs, stems, leaves, flowers, fruits and seeds. The ITS2 sequences were amplified and sequenced bidirectionally. The ITS2 sequences were identified using Basic Local Alignment Search Tool (BLAST) method in the GenBank database and DNA barcoding system to identify the herbal medicine. The genetic distance was analyzed using the Kimura 2-parameter (K2P) model and the Neighbor-joining (NJ) phylogenetic tree was constructed using MEGA 6.0. The results showed that DNA can be extracted successfully from 93 samples and high quality ITS2 sequences can be amplified. All 31 herbal medicines can get correct identification via BLAST method. The ITS2 sequences of raw material medicines, ultrafine powder and cell wall-broken powder have same sequence in 26 herbal medicines, while the ITS2 sequences in other 5 herbal medicines exhibited variation. The maximum intraspecific genetic-distances of each species were all less than the minimum interspecific genetic distances. ITS2 sequences of each species are all converged to their standard DNA barcodes using NJ method. Therefore, using ITS2 barcode can accurately and effectively distinguish ultrafine powder and cell wall-broken powder of herbal medicine. It provides a new molecular method to identify ultrafine powder and cell wall-broken powder of herbal medicine in the quality control and market supervision.

Objective To investigate the expression of connective tissue growth factor( CTGF) and the effects of azithromycin in airway remodeling in asthmatic mice.Methods BALB/c female mice were randomly divided into 3 groups;control group(A),asthma group(B) ,and azithromycin treated group(C),with 10 mice in each group.Mice were sensitized and challenged continually with ovalbumin( OVA).The distribution and types of collagens were detected by cirius red staining.Lung hydroxyproline content was determined by acid hydrolysis.CTCF expression in mice pulmonary tissues was detected by SABC immunohistochemistry.Results After continual challenging with OVA,collagen hyperplasia was found in the airway wall and CTCF positive expression in airway epithelium.CTCF expression was closely associated with lung hydroxyproline content(r = 0.65,P <0.01).Conclusion Asthma continually challenged with OVA could result sub-epithelial fibrosis and remodeling in airway,which could be associated with the upregulation of CTCF over-expression.Azithromycin inhibited airway remodeling in asthmatic mice,possibly by inhibiting the expression of CTGF.
