Objective To investigate the clinical features,treatment,medication and abnormal metabolism control status in elderly benign prostatic hyperplasia (BPH) with metabolic syndrome (MS).Methods The 397 patients with BPH aged ＞60 years (294 with MS) were retrospectively analyzed.The clinical features,treatment and control status were analyzed.Results Body mass index,waist circumference (BMI),2 hPBG,systolic pressure,diastolic pressure,TG and uric acid,urinary albumin/creatinine ratio,urinary albumin were higher and HDL-C was lower in BPH with MS than without MS (P＜0.05).Prostate volume,PSA level,IPSS score,quality of life score were higher in BPH patients with MS than without MS (P＜0.05).Treatment modality analysis showed that lower urinary tract symptoms was mild,watchful waiting accounted for 22.3％,urinary retention or obstruction related operation treatment for 8.7％,moderate to severe symptoms related oral drugs treatments for 67％,the oral drug treatment was still the main mode of BPH.In the patients with abnormal levels of glucose metabolism,the target arrival rate (TAR) on FBG,2 hPBG and HbAlc were 49.6％,34.9％ and 37.5％,TAR on all the three was 19.1％.In the hypertensive population,TAR on systolic and diastolic pressure were 44.1％ and 82.5％,TAR on both two was 41.7％.TG,TC,LDL-C and HDL-C were 31.3％,35.4％,48.2％ and 64.9％,on all the four was 29.9％.Conclusions The ratio of elderly BPH with MS is high,but the target arrival rate on control of urinary tract symptoms and abnormal metabolism component is not optimistic in spite of a positive drug administration.

Objective To construct lentivirus vectors carrying alphastatin gene, test its secretion expression in human umbilical vein endothelia cells (HUVECs) and observe its effects on growth, migration and tube formation of HUVECs. Methods We constructed recombinant lentivirus vectors of NT4-alphastatin fusion gene containing neurotrophin-4 signal peptide, pro-region sequences and alphastatin, then transfected the recombinant lentivirus vectors into HUVECs to obtain secretory protein alphastatin and test its anti-angiogenic activities in vitro. Results Our data showed that recombinant self-inactivating lentivirus vectors of NT4-alphastatin were successfully constructed, and stable NT4-alphastatin transduced HUVECs were capable of sustainably secreting alphastatin which significantly suppressed HUVECs migration and differentiation but not VEGF-induced proliferation. Conclusion This report represents the first time on the use of lentivirus-based vectors to deliver alphastatin, the endogenous angiogenesis inhibitor, and reveals the potential utility of anti-angiogenic gene therapy with lentivirus vectors for treating cancer.

In 40 cases who were treated with external fixator, the cure rate for hemorrhagic shock was 90%, the mortality 2.5%, and the average ISS score 9.8. Conclusion The treatment of unstable pelvic fracture with external fixator is simple and reliable, and can reduce the mortality significantly.

Objective To observe the pathologic features on cardiac allograft and to test archived endomyocardial biopsy specimens for antibody-mediated rejection specific marker-C4d deposition and its characteristics by using immunoperoxidase (IP) techniques. Methods From January 2003 to December 2007,10 recipients underwent orthotopic cardiac transplantation and 17 specimens of endomyocardial biopsy were obtained either for a protocol basis (generally at 1 st month,3rd month,1st year and 2nd year post-transplant) and on immediate clinical indications.All specimens of endomyocardial biopsy were collected for histopathological examination and C4d immunohistochemical staining,simultaneously. All pathological diagnoses were done according to 2004 International Society for Heart and Lung Transplantation (ISHLT) recommendation working formulation and AMR Schema,and C4d staining intensity were graded and recorded as 0 to 3 +.Results Except 1 specimen unqualified,all 16 consecutive specimens of endomyocardial biopsy were qualified.There were 4 cases of acute T cell-mediated rejection (all graded 1 ),2 cases of Quilty lesion,and 7 cases of antibody-mediated rejection,who were documented according to ISHLT Schema and C4d deposition.Meanwhile,there were 6 cases showing evidence of antibody-mediated rejection without concurrent acute cellular rejection and only one case concordant with acute T cell-mediated rejection.One case of antibody-mediated rejection died 20 months posttransplantation due to combined transplant coronary artery disease (TCAD). The C4d in the cardiac allograft was deposited in microvasculature diffusively.Conclusion Antibody-mediated rejection is an important clinical entity following orthotopic heart transplantation and is difficult to diagnosis except to perform endomyoeardial biopsy.Immunoperoxidase staining for C4d is a sensitive and specific technique for detecting one marker of antibody-mediated rejection.

Objective To prepare recombinant adenovirus pAd-gal-9 containing murine galectin-9 and explore galectin-9's pro-apoptotic effect on T lymphocytes. Methods The recombinant adenovirus plas-mid pAd/CMV/V5-DEST-gal-9 was prepared by conventional molecular cloning and LR reaction. The pAd/ CMV/V5-DEST-gal-9 linearlized by Pac I was transfected into 293A cells with Lipofectin 2000. Eight days after transfection, the 293A cells were subjected to freeze/thraw circle for three times and the supernatant was collected after centrifugation. Higer titer pAd-gal-9 was produced by large-scale infection of 293A cells with the supernatant containing pAd-gal-9. The supernatant was condensed to get purified pAd-gal-9 by CsCl density gradient centrifugation. After titer determination with gradient dilution of harvested pAd-gal-9 infec-tion in 293A-seeded 96-wells, pAd-gal-9 was used to infect the CHO cell line. Immunohistological assay, Western blot and flow cytometry were employed to ascertain the subcellular location expression of galectin-9. We added solid-phase transgenic CHO cells or freshly-cultured supernatant to medium containing activated T cells to detect the pro-apoptotic effect of galectin-9. Results The pAd-gal-9 was prepared successful. Im-munohistochemical staining of CHO infected with pAd-gal-9 confirmed that galectin-9 was expressed in the cytosol. Intercellular staining indicated that mean fluorescence intensity of galectin-9 was significantly higher in pAd-gal-9-infected CHO group than control group. Supernatant from pAd-gal-9-infected CHO promoted the apoptosis of T cells. The percent of apoptotic T cells was higher than the Tim-3 positive T cells. Conclu-sion CHO infected with pAd-gal-9 can secret galectin-9 to promote the apoptosis of activated T cells via Tim-3-independent mechanisms.

Objective Adhesion or too highly located folds upper eyelid and even hlepharoptosis are common complications after double eyelid operation. The method was designed to correct these de-formities. Methods The incision of upper eyelid was designed under the scar. Skin was resected between the former and the new double line, if there was excessive skin. Completely relieve the adhesion until nor-mal tissue was exposed. Expose lateral extension of retro-orbicularis oculi fat pad. An upper pedicle fat flap was formed after cutting tissues off along bilateral borders. Appropriately and transversely cutting lateral portion of the pedicle made it rotate inside downward with enough blood supply. The fat flap was fixed with released orbital fat and the lower edge of fat flat fixed with upper border of supratarsal to restorate the volume. For severe condition, fat granule injection could be used after the skin was sutured. Results 42 cases (80 eyes) were treated in the past two years. The deformities of 32 cases were corrected by the application of retro-orbicularis oculi fat pad. Fat granule injection was applied for the other 10 pa-tients meanwhile. 30 cases (60 eyes) were followed up for 6 to 24 months. The results were satisfactory. Conclusion The methods are performed easily and the results are satisfied. It is worth of recommenda-tion.

BACKGROUND:Spinocerebel ar ataxia is a inherited neurodegenerative disease with progressive cerebel ar masonic movement disorders as the main clinical manifestation. So far, no drug is available to control the disease progression. OBJECTIVE:To observe the clinical effect of umbilical cord mesenchymal stem cells in treating spinocerebel ar ataxia by intrathecal injection. METHODS:Thirty-eight cases of spinocerebel ar ataxia were given umbilical cord mesenchymal stem cells by intrathecal injection, 1×106/kg once a week, four times as a course. These 38 cases received 52 courses. Among them, 27 cases received 1 course, 8 cases received 2 courses and 3 cases received 3 courses. International Cooperative Ataxia Rating Scale (ICARS) and Activity of Daily Living Scale (ADL) were used to evaluate patients’ neural functions (the greater scores, the more severe damage) and ability of daily living (the lower score, the stronger the ability of daily living). After treatment, al patients were subjected to fol ow-up visit. RESULTS AND CONCLUSION:The total effective rate of 52 courses of treatment was 84.62%. ICARS and ADL scores were significantly decreased at 1 month after treatment (P<0.01). In most of effective patients, unstable walking and standing, slow movement, upper limb fine motor disorder, writing difficulties, dysarthria, eye movement disorders were improved. After treatment, common adverse effects were dizziness (1 case), low back pain (2 cases), headache (1 case), and fever (2 cases). Al these symptoms disappeared within 1-3 days. No treatment-related adverse events happened in the median fol ow-up of 39 months (11-59 months). The il ness of effective patients had been stable for 1-19 months, average (5.95±4.84) months. Intrathecal injection of umbilical cord mesenchymal stem cells is safe to ameliorate clinical symptoms to some extent within a certain time. It may delay the progression of spinocerebel ar ataxia. Multiple courses of treatment can help to further improve neurological function in most patients.

To identify acute renal allograft rejection biomarkers in human serum, two-dimensional differential in-gel electrophoresis (2-D DIGE) and reversed phase high-performance liquid chromatography (RP-HPLC) followed by electrospray ionization mass spectrometry (ESI-MS) were used. Serum samples from renal allograft patients and normal volunteers were divided into three groups: acute rejection (AR), stable renal function (SRF) and normal volunteer (N). Serum samples were firstly processed using Multiple Affinity Removal Column to selectively remove the highest abundance proteins. Differentially expressed proteins were analyzed using 2-D DIGE. These differential protein spots were excised, digested by trypsin, and identified by RP-HPLC-ESI/MS. Twenty-two differentially expressed proteins were identified in serum from AR group. These proteins included complement C9 precursor, apolipoprotein A-IV precursor, vitamin D-binding protein precursor, beta-2-glycoprotein 1 precursor, etc. Vitamin D-binding protein, one of these proteins, was confirmed by ELISA in the independent set of serum samples. In conclusion, the differentially expressed proteins as serum biomarker candidates may provide the basis of acute rejection noninvasive diagnosis. Confirmed vitamin D-binding protein may be one of serum biomarkers of acute rejection. Furthermore, it may provide great insights into understanding the mechanisms and potential treatment strategy of acute rejection.

Objective This study aimed to establish a reliable primary culture protocol for preparing murine spleen-derived mesenchymal stem cells ( MSCs) by tissue explant culture.Methods Healthy mouse spleens were crushed by syringe handle to harvest spleen mesenchymal tissues.Then the tiny pieces of spleen tissue were digested by collagenase II before seeded into culture flasks.The morphological characteristics of spleen tissue-derived cells were observed under the inverted microscope.Further, the surface antigen profile of the cells was analyzed by flow cytometry (FACS).The cells were induced to differentiate into osteoblasts and adipocytes.Results The murine spleen-derived MSCs exhibited a spindle-shaped appearance.The FACS results showed that the spleen-derived MSCs highly expressed CD29, CD44, CD105 and Sca-1, but weakly expressed CD11b, CD34, CD45 and Ia. In addition, the spleen-derived MSCs steadily differentiated into osteoblasts and adipocytes in the induction medium.Conclusions A method of primary culture of murine spleen-derived MSCs by explant culture is successfully established.The harvested MSCs exhibit high purity and cell proliferation ability, and provide a reliable cell model for related researches.
