BACKGROUND:Titanium materials have high mechanical strength, stable physical properties, good biocompatibility, and excelent corrosion resistance, which can be safely used in humans. OBJECTIVE:To compare the safety of mesh-like titanium aloy steel plateversus wire mesh in the repair of chest wal defects. METHODS:Eighteen patients with chest wal defects, 11 males and 7 females, with an age range of 19-65 years, were enroled. The 9 of 18 patients were subjected to repair with mesh-like titanium aloy steel plate, and the other 9 patients underwent wire mesh repair. At 1 week after repair, visual analog scale scores were measured in the two groups, and patient’s satisfaction on the thoracic appearance and incidence of complications were surveyed during the folow-up. RESULTS AND CONCLUSION: Al patients were folowed up for 1-7 years. During the folow-up, X-ray review displayed good thoracic stability and no fracture of titanium plate and wire mesh. Patients recovered wel from respiratory dysfunction, with unapparent chest wal deformity and high satisfaction rate of the thoracic appearance. Moreover, compared with the wire mesh group, the satisfaction rate of the thoracic appearance was significantly higher (P< 0.05), but the incidence of complications was significantly lower in the titanium plate group (P < 0.05). At 1 week after repair, the visual analog scale scores had no difference between the two groups (P> 0.05). These findings indicate that the mesh-like titanium plate has good biocompatibility and safety to effectively maintain the stability of the chest wal.

Mouse AtlasTM cDNA Arrays were used for comparative studies of gene expression in mouse embryonic fibroblasts (MEF) before and after in vitro cultivation and 24 types of differentially expressed genes were identified. To screen and identify the differentially expressed new genes of MEF, cDNA suppression subtractive hybridization (SSH) technique was used. The cDNAs derived from cultured MEF after SSH were subcloned into pGEM T easy vectors to set up the subtractive library, transfected into E. coli strain JM109, sequenced and analyzed with bio informatics methods after PCR amplification.Altogether 42 types differentially expressed genes and 3 novel ESTs were identified and categorized from total 128 ESTs derived from cultured MEF after SSH. It is suggested that the genes expressed by MEF were the important molecular basis supporting the survival, proliferation and self renewal capacities of embryonic stem cells.

Objective To improve the diagnosis and treatment of adenocarcinoma of bladder. Methods The data of 20 cases of adenocarcinoma of bladder from 1986 to 2004 were retrospectively analyzed. All patients underwent operation and the diagnosis was proven by histopathologic examination. Results Eighteen cases were primary adenocarcinoma of bladder,8 cases applied to radical cystectomy and 10 cases partial cystectomy. Two cases were urachal adenocarcinoma,and received extended partial cystectomy.Seventeen patients were followed up for 3 months to 5 years. The one-year survival rate was 52.9% (9/17),two-year survival rate 41.2% (7/17),and five-year survival rate 29.4% (5/17). Conclusion Radical total cystectomy is the best choice for primary adenocarcinoma of bladder and extended partial cystectomy for urachal adenocarcinoma. Radiotherapy and chemotherapy after operation can improve the treatment effect.

Objective To study the molecular mechanism of the apoptosis in rat tubular epithelial cells induced by albumin in vitro.Methods The cultured rat renal tubular epithelial cells were incubated with 20 mg/ml delipidated and endotoxin-free bovine serum albumin(BSA) for 2,6,12 and 24 h respectively.The NF-?B activity was assessed by electrophonetic mobility shift assay(EMSA) and the osteopontin(OPN) mRNA expression was analyzed by reverse transcription-polymerase chain reaction(RT-PCR).The cell apoptosis was evaluated by flow cytometry.Results The rate of apoptosis was increased when the cultured rat renal tubular epithelial cells were incubated with 20 mg/ml BSA for 2,6,12 and 24 h respectively.The NF-?B activity and expression of OPN were up-regulated in the cultured rat renal tubular epithelial cells with the treatment of BSA,with significant difference compared with those of the control group(P

Protein is the executor of physiological function, and direct embodiment of the life phenomena. Proteomics aims to systematically clarify all or parts of proteins' role and function in life movement. In post genome era, proteomics began to play more important role in life science field. Actinobacteria are closely linked to human production and life, which have produced many clinically important secondary metabolites, including antibiotics, antitumorals and enzymes. Actinobacterial systematics and its model organism Streptomyces coelicolor in 2001 genome sequence laid the foundation for further functional genomic studies. Actinobacterial proteomics was more directly and exactly to interpret the activity of life than genomics and transcriptomics, which grew much faster and received so much attention from scientists in the near years. Complex morphological differention, stronge environment adaptiveness, nitrogen-fixing capacity, metabolic mechanism, pathogenicity and natural produces' discovery were systematically reviewed in this study, which was expected to be the basis for promoting Actinobacterial proteomics study in the near future.

Objective To explore a new method of parapancreatic abscess treatment and establish an idea of minimally invasive technologies for parapancreatic abscess to improve the recovery rate of acute pancreatitis. Methods The patients had experienced percutaneous puncture and placed drainage tube under the ultrasound guidance first, then the sinus tract was expanded gradually to 24F perimeter by Cook's fascia expender. Finally, the necrotic tissue and pyogenic membrane was removed and repeatedly washed under guidance of choledochoscopy. Results The recovery rate was 91.1 %(33/36). The complication incidence was 10.7% (hemorrage:2 cases, external intestinal fistula:3 cases, and fatal MOF: 1 case). Conclusions The viewpoint which parapancreatic abscess only can be cured by drainage operation can be changed by associating debridement by choledochoscope with percutaneous puncture drainage under the ultrasound guidance. It is a simple, safe and effective method. It can be used to reduce the patients' damage, complication and mortality and accomplish the idea of damage control by minimally invasive technologies.

OBJECTIVETo analyze the effect of Chinese herbs used by Prof. LI Tao on peripheral blood T subsets in treating multiple sclerosis (MS) by using association rules and statistical methods, thereby providing evidence for optimizing prescriptions.

METHODSData of MS inpatients and outpatients recorded by data collecting system, Xiyuan Hospital, China Academy of Chinese Medical Sciences were resorted. The relationship between Chinese herbs and T cell subsets were analyzed using SPSS17.0 and Aprior module in SPSS Clementine 12.0.

RESULTSRadix bupleuri, Radix Paeoniae alba, Fructus Aurantii, Atractylodes, and Radix Glycyrrhizae were most commonly used herbal combinations.Radix Aconiti lateralis preparata and Rhizoma Smilacis glabrae were often added. Radix Aconiti lateralis preparata was associated with decreased Th1 cells (confidence level 83.78%, supportive level 36.26%). Decreased Th1 cell was associated with Radix Aconiti lateralis preparata (confidence level 71.26%, supportive level 36.26%).Radix Aconiti lateralis preparata was obviously associated with decreased Th1 cells. Radix Bupleuri, Radix Paeoniae alba, bitter orange, Atractylodes , Radix glycyrrhizae, and Radix Aconiti lateralis preparata could reduce peripheral blood Th1 subsets of MS patients and elevate Th2 subsets (all P < 0.01).

CONCLUSIONSThe herbal combination of Radix Bupleuri, Radix Paeoniae alba, Fructus Aurantii, Atractylodes, Radix Glycyrrhizae, Rhizoma Smilacis glabrae, and Radix Aconiti lateralis preparata could lower peripheral blood Th1 cells and elevate Th2 cells, and prevent the relapse of MS possibly by reducing Th1 cells and elevating Th2 cells. Especially Radix Aconiti lateralis preparata played important roles in aforesaid changes of Th1 and Th2.
