Aim To investigate the ameliorative effects pseudoberberine(Y53), a berberine(BBR) analogue, on diabetic nephropathy( DN) in streptozotocin( STZ)-induced diabetic mice. Methods Diabetes mellitus ( DM) of the C57BL/6J mice was induced by intraper-itoneal injection of STZ at 120 mg·kg-1 . The diabetic animals were divided into 4 groups, which were orally treated with saline, 50 mg · kg-1 of BBR, 50 mg · kg-1 of Y53 or 5 mg · kg-1 of rosiglitazone ( ROSI ) , respectively. During and after the experiment, the u-rine, blood, serum and kidney of the animals were harvested for determination of relevant parameters by kits. Kidney tissues of the mice were subjected to pathological examination by hematoxylin & eosin( HE) staining;mRNA and protein expression levels of target genes in the kidney were determined by quantitative re-al-time reverse transcriptase-polymerase chain reaction ( qRT-PCR) and Western blot, respectively. Results Y53 greatly reduced the fasting blood glucose ( FBG ) and glycosylated hemoglobin( GHb) , improved diabet-ic symptoms such as polyphagia and polyuria in the di-abetic mice( P<0. 01 vs DM control group) . Y53 po-tently reduced the blood urea nitrogen ( BUN ) , serum creatinine( Scr) , 24 h urinary protein, kidney index, serum and kidney advanced glycation end-products ( AGEs) and nitric oxide( NO) , as well as kidney cho-lesterol( CHO ) and triglyceride ( TG ) contents ( P <0. 05 or P<0. 01 vs DM control group) . In the patho-logical examination, Y53 greatly restored kidney mor-phology and suppressed glomerular sclerosis( P<0. 001 vs DM control group). In addition, Y53 significantly reduced the renal expression of fibrosis-related genes, such as the transforming growth factor-β1 ( TGF-β1 ) and smad2(P<0. 01 vs DM control group). The reno-protective efficacies of Y53 were superior to those of BBR and ROSI in our study ( P<0. 05 or P<0. 01 ) . Conclusions The BBR analogue Y53 has potent ac-tivities in ameliorating renal injury and restoring renal function in STZ-induced diabetic mice. Y53 may be developed as a novel kind of agent for the treatment of DN in the future.

Objective To investigate the surgical strategy for degenerative lumbar scoliosis (DIS)and evaluate the clinical results of the posterior correction and fusion technique. Methods From May 2003 to May 2009,27 patients with DIS were treated posterior operation. All the patients were performed posterior laminectomy,spinal fusion and correction with pedicle screws system. Among the patients, 18 cases with posterolateral bone grafting,9 cases complicated spondylolishesis with PLIF intervertebral combined with posterolateral fusion. Results All the cases were followed up for a minimum of 12 months and 88.9% (24/27) of them had excellent or good outcome, Oswestry score was(21.54 ± 1.95 )%;22 cases were followed up for 24 months and showed a rate for excellent or good results of 86.4%( 19/22),and Oswestry score was (24.26 ± 2.32)%. Oswestry scores of the postoperative 12,24 months were lower than that before operation (57.83 ± 2.71 )%. There was statistical difference in the cases preoperation and postoperation. Correction of scoliosis of the coronal plane was 47.2%. Preoperative lumbar lordosis was augmented from 23.6°± 8.3° to 43.8°± 9.1°. One case complicated with wound infection during perioperation period, and 2 eases with heart diseases. The screw of 1 case was loosening at 3 months postoperation. Conclusion Decompressing thoroughly and improving lumbar lordosis, the operation of posterior correction and bone graft fusion shows good results for degenerative lumbar scoliosis.

Ten pharmacophore models of beta-tubulin inhibitors were established from the training set of seventeen beta-tubulin inhibitors (two categories) with comformer analysis by using the Catalyst software. The optimal pharmacophore model with two hydrophobic units and two hydrogen bond acceptor units were confirmed (RMS = 0.43, Correl = 0.98, Weight = 2.06, Config = 15.97). This pharmacophore model is able to predict the activity of known beta-tubulin inhibitors and can be further used to identify structurally diverse compounds with higher activity.

Objective To discuss the relation between level of Hs-CRP and glycometabolic disturbance in patients with acute coronary syndrom. Methods 155 patients with acute coronary syndrome were divided into 3 groups according to the WHO standard of diabetes diagnosis,normal glucose tolerance group(group A,44 cases),impaired glucose tolerance group(group B,60 cases),diabetes group(group C,51 cases). All cases were checked by the 75g glucose tolerance test, blood Glucose, insulin, HbA1c,lipid,hypersensitive C reaction protein(hs-CRP). 95 patients were checked by coronary angiography(CAG). Statistic comparison were measured among three groups including the levels of hs-CRP,insulin,HbA1c,lipid and coronary artery lesions. Results The levels of Hs-CRP,PBG, FINS, PINS,HbA1c,TC,LDL-C in both group B and C were higher than those in group A;The levels of TG,PINS were not found significant differences between group B and C. The level of Hs-CRP was correlated with the levels of PBG,PINS,HbA1c,TC,LDL-C. The coronary artery lesions showed by CAG in group B and C were more severe than those in group A,coronary multivessel changes in group B and C were more frequent than in group A,it had no significant difference between group B and C.Conclusion Compared with the patients of normal glucose tolerance, patients with glycometabolic disturbance have higher levels of hs-CRP,their coronary artery lesions are more severe.

Objective To explore the imaging characteristics of the ovarian thecoma-fibroma.Methods The clinical imaging characteristics of 25 patients with thecoma-fibroma were retrospectively analyzed. Results A total of 27 lesions were seen in 25 patients, and the maximum diameter of the tumors was 1.2 - 15.0 cm, with an average diameter of 6.9 cm. The tumors whose maximum diameter larger than 6 cm were mainly as cysticsolid. Twenty-six lesions were well-defined margin, and 14 lesions were round and oval masses, 9 lesions were lobulated masses, 3 lesions were irregular masses, and 1 lesion presented with unclear boundary. A total of 10 lesions in 9 cases were performed with CT scan, and the density was similar to uterine muscle density. In MRI scan of a total of 17 lesions of 16 cases, all lesions showed hypointensity on T1WI. On T2WI, 8 lesions showed slightly hyperintensity, 7 lesions appeared slight hypointensity, and 2 lesions appeared significantly hypointense. Eight lesions showed slit hyperintensity. Enhancement scanning was performed in seven cases. Five cases showed mild to moderate enhancement, 1 case was enhanced obviously, and 1 case was not strengthened. Conclusions The imaging findings of the ovarian thecoma-fibroma have somewhat features and can indirectly reflect pathology of tumor. Combined with the clinical data, imaging characteristics are is helpful to the diagnosis and differential diagnosis of the disease.

Objective To evaluate the effect of preoperative radiotherapy and postoperative brachy radiotherapy (POBRT) on patients with primary liver cancer(PLC). Methods 50 patients with PLC were randomly divided into 2 groups:(1)Radiotherapy group, 25 patients who underwent preoperative radiotherapy 14～17 days before hepatectomy and POBRT 3～10 days after hepatectomy ;(2)Control group,25 cases who underwent hepatectomy only. In radiotherapy group, before heptectomy, the single-dose 6Gy per time and 3 sessions were given to each patient. 3～6 ductus were placed for POBRT during operation,and 10Gy of POBRT per time and 2～4 sessions were given postoperatively. In control group,no radio cherapy was given before and after hepatectomy. Results In radiotherapy group, the cancer shrank significantly after preoperative radiotherapy (P

Scavenger receptor CD36 could bind and endocytose oxLDL into macrophages which were then differentiated into foam cells that constitute the atherosclerotic lesion core, and was considered to be a potential target to treat atherosclerosis. In the establishment of the compound library of berberine (BBR, 1) analogues, we discovered that 13-hexylberberine (2) showed an antagonistic activity against CD36. Taking 2 as the lead compound, 21 derivatives were synthesized and their antagonistic activities were evaluated via an ELISA-like high-throughput screening (HTS) model. The primary structure-activity relationships were studied. It was indicated that the introduction of suitable groups at the 2- and 3-position of the aromatic ring A or at the 9-position of the aromatic ring D could enhance the activity. Among the 21 studied compounds, 7g bearing a benzyloxyl group at the 9-position provided a highest CD36 antagonistic activity with the IC50 value of 7.7 micromol L(-1). Besides, its antagonistic activity was further verified with Sf9 insect cell HTS model. So berberine analogues are a new family of CD36 receptor antagonists and worthy to be studied further.
