Objective To compare the efficacy of Lichtenstein and transabdominal preperitoneal patch repair(TAPP) in the treatment of primary inguinal hernia in adults. Methods The clinical data of 223 patients who received Lichtenste and 121 patients who underwent TAPP in our hospital between January 2002 and January 2006,were analyzed retrospectively.The efficacy and complications of the two methods were compared.Results The rate of intraoperative injury of the inner organs in the TAPP group was significantly higher than that in the Lichtenstein group [5.8%(7/121) vs 0.4%(1/223),?2=7.626,P=0.006],while no significant difference was detected in the rate of abdominal organ injury between the two groups [0.8%(1/121) vs 3.1%(7/223),?2=0.969,P=0.325].The rate of postoperative complications in the TAPP group was significantly lower than that in the Lichtenstein group [14.0%(17/121) vs 36.3%(81/223),?2=18.881,P=0.000].In the TAPP group,during a follow-up of(14?7) months,one case of recurrence was found(0.8%).Whereas in the Lichtenstein group,the patients were followed up for(16?8) months,two of them had recurrence(0.9%).No significant difference existed in the recurrence rate between the two groups(?2=0.000,P=1.000).Conclusions Both the Lichtenstein and TAPP have benefits and drawbacks.Individulized therapy is recommended for the patients with inguinal hernia.It is important for surgeons to know the indications of the operations.

?AlM: To evaluate the clinical effects and security of posterior chamber implantable Collamer lens ( lCL ) implantation in patients with extreme highly myopia.
?METHODS:ln this study, 18 patients ( 32 eyes ) with extreme highly myopic patients who had undergone posterior chamber lCLs implantation from July 2010 to July 2013 were evaluated. Diopter -10. 5 ~ 19. 0D, and astigmia -0. 5 ~4. 5DC. Changes in intraocular pressure ( lOP ) , refraction, visual acuity and corneal endothelium, anterior chamber depth, iris, high arch, lens were noted at 1d, 1wk, 1, 3mo and 1a after surgery respectively, and follow-up was of 1a.
? RESULTS: Before surgery, the uncorrected visual acuity (UCVA) were 0. 01~0. 05, and the best spectacle-corrected visual acuity ( BSCVA) were 0. 4 ~ 1. 0. One month after surgery, the UCVA were 0. 5~1. 2. The mean vault were 547±222 μm (95%CI 442~672μm) and 528±268μm (95%CI 354 ~635μm) for 1mo and 1a, respectively (P = 0. 81), and there was no significant difference. Anterior subcapsular opacities in 1 eye, mild and transient increase in lOP in 3 eyes, and chronic pigment dispersion in 2 eyes were observed. There was no serious complication.
?CONCLUSlON: Posterior chamber phakic intraocular lens implantation is an effective and safe method for correcting patients with extreme highly myopia.

To investigate the therapeutic effects and associated complications of allogeneic peripheral blood stem cell transplantation (allo-PBSCT). 40 patients with various malignant hematopoietic diseases received allo-PBSCT. The preparative regimens were based on BUCY2 or modified BUCY2. The acute graft-versus host disease (aGVHD) was prevented by cyclosporin A and short-term MTX regimen in all patients. Two patients from donors with one fully mismatched HLA on DRB1 locus and 4 from unrelated donor also administered Zenapox (CD25 MAb) at dosage of 1 mg/kg every day on the day before transplantation and day 4 after transplantation. These 6 patients were also treated with mycophenolate mofetil (MMF). Transfusion of the donor cells: The median of the transfused nucleated cells was 5.38 x 10(8)/kg and that of the CD34+ cells was 7.8 x 10(6)/kg respectively. All the patients gained hematopoietic reconstruction except one who died of infection before engraftment. Seven patients got II degrees-IV degrees aGVHI) and the incidence was 17.5%. Fourteen patients got cGVHD and the incidence was 53.8% in the patients who survived over 6 months. Twenty-eight patients had fever or other characteristics of infection. The median follow-up time was 13.8 months. The incidence of transplantation related mortality (TRM) was 17.5% and 2 patients relapsed (5.0%). It was concluded that allo-PBSCT can reconstruct hematopoiesis quickly and is a favorable therapeutic method for leukemia.

In the late part of the 20th century, due to the change of disease spectra, rapid increase of health expenditure and imbalanced distribution of health resources, the health management sectors and doctors increasingly demand the scientific decision-making. With the development of clinical evidences and research, evidence-based medicine (EBM) became emerged in the early 1990's. EBM, the medical science in compliance with the best available clinical evidence, integrates clinical epidemiology (CE), systematic reviews (SRs) and health technology assessment (HTA) as the major technology, to emphasize that the clinical practice should be based on the combination of the best available clinical evidence, medical experiences and patient desire to cope with the demand of medical decision-making. Some governments and international organizations like WHO, and Australia have now adopted the high-quality evidence of EBM for decision-making. As the largest developing country, China is challenged by variety of health problems. The introduction, adaptation and implementation of EBM will improve the decision-making and health care services, which should enhance the competitive capacity of medical and pharmaceutical manufactures, as well as promote the popularization of EBM, and protect the doctors and patients rights.

OBJECTIVETo construct plant expression pCAMBIA1301-PMI by substituting PMI for hygromycin resistance gene in pCAMBIA1301 and obtain transgenic Salvia miltiorrhiza f. alba using PMI-mannose selection system.

METHODThe 6-phosphomannose isomerase gene (PMI) of Escherichia coli was amplified by PCR. Sequence analysis showed that it shared 100% amino acids identities with the sequences of PMI genes isolates reported in the NCBI. Based on pCAMBIA1305, the plant expression pCAMBIA1305-PMI was constructed successfully by substituting PMI for hygromycin resistance gene in pCAMBIA1305. pCAMBIA1305-PMI was transformed into Agrobacterium tumefaciens LBA4404, and then the leaves of S. miltiorrhiza f. alba were inoculated in LBA4404 with pCAMBIA1305-PMI.

RESULTPlant expression pCAMBIA1301-PMI was successfully constructed and the leaves of S. miltiorrhiza f. alba inoculated in LBA4404 with pCAMBIA1305-PMI were selected on medium supplemented with a combination of 20 g x L(-1) mannose and 10 g x L(-1) sucrose as a carbon source. The transformation efficiency rate was 23.7%.

CONCLUSIONGenetic transformation was confirmed by PCR, indicating that a new method for obtaining transgenic S. miltiorrhiza f. alba plants was developed using PMI-mannose selection system.

In order to explore the relationship between human papilloma virus ( HPV) and upper gastrointestinal cancer(esophageal cancer), An esophageal squamous cell carcinoma(ESCC) tissue was obtained from a 76 year old Chinese female patient from Anyang city, a high-incidence area for esophageal cancer, in China. Transplanted tumor was formed through direct SCID mouse tumorigenicity experiment and cultured monolayer cells were obtained after several passages and screenings Immunofluorescence test, cell growth curve, soft agar assay, chromosome analysis and tissues HE staining were also performed to confirm the epithelial cell origin. Cell DNA STR typing results showed that no three alleles was observed,indicating no contamination of human cells. DNA analysis revealed the presence of HPV type 18 DNA in this cell line. DOLINK test found the E6 protein expression of HPV virus. We concluded that the established cell line is a new esophageal squamous cell-origincarcinoma cell line with HPV DNA positive and expression of viral oncoprotein. It provides new cytologic material for performing etiology studies on the occurrence and development of esophageal cancer.
