Mycoepoxydiene is a novel antitumor agent extracted from marine lignicolous fungi HLY-2, which is Diaporthe phaseolorum by molecule identification. The medium optimization for mycoepoxydiene by orthogonal design and the comparison of submerged fermentation and solid state fermentation were studied. The rusult is that the maximal yield of the compound is 543mg/L, which is 43 times compared to the customary half-seawater PD medium and 15 times to the best submerged condition. This optimum culture medium included potato 250g/L, seawater 300mL/L, glucose 30g/L, lactose 50g/L, KH_ 2 PO_ 4 0.65mmol/L and (NH_ 4 )_ 2 SO_ 4 1g/L in the solid state condition. Differentiation analysis between submerged and solid state fermentation, and antitumor activity of these ferment products were also studied. The antitumor activity of products of the optimum medium approached the pure compound.

OBJECTIVETo investigate the clinical effects of plate and xenogenic bony plate for the treatment of nonunion of femoral shaft fracture after initial fixation with locked intramedullary nailing.

METHODSFrom February 2006 to June 2013, 21 cases with nonunion of femoral shaft fracture after initial fixation with locked intramedullary nailing were treated with femoral plate and contralateral xenogenic bony plate. There were 12 males and 9 females with an average age of 34.8 years old (ranging from 18 to 62 years). The time of nonunion was 9 to 18 months (averaged 12.8 months). The clinical outcomes of the treatment were evaluated by Merchan assessment.

RESULTSAll of the patients were primary healing, and on complications such as infection,fat embolism, internal fixation breaking or rotational deformity, shortening were occurred. All the cases were followed up for 13.2 months (ranging from 8 to 24 months). Nineteen cases were bone healed,the time of union averaged 6.2 months (ranging from 4 to 9 months). Two cases appeared delayed union and gained bony union after 7 to 13 months' observation. According to the criterion of Merchan,the results were excellent in 13 cases, good in 6 cases, poor in 2 cases.

CONCLUSIONTreatment of nonunion of femoral shaft fracture after initial locked intramedullary fixation with plate and xenogenic bony plate has advantages of high curative rate and low complications, good postoperative function recovery, it is a reliable treatment to elevate the stability of fixation and promote the osteogenesis.

Pharmaceutical preparations, particularly as a "secret recipe" of traditional Chinese medicine in medical institutions, are the product of China's medical and health industry, and they are also an important means of competing of different medical institutions. Although pharmaceutical preparations have advantages and characteristics than institutes for drug and pharmaceutical companies, the quality standards of pharmaceutical preparations in medical institutions has not reached the desired level over the years. As we all know, the quality of pharmaceutical preparations is important to ensure the efficacy, especially under the environment of people pay more sttention on drug safety and effectiveness and contry increase emphasis on the stste of pharmaceutical preparations. In view of this, we will improve the grade, stability, and clinical efficacy of pharmaceutical preparations by the advanced equipment, testing instruments and the process dynamic quality control technology. Finally, we hope we can provide new ideas for the quality control of pharmaceutical preparations.

OBJECTIVETo identify potential mutation responsible for synpolydactyly (SPD) in a large Chinese kindred and to offer genetic counseling and prenatal diagnosis for the members of the family.

METHODSAll family members were examined clinically, and blood samples were obtained for linkage analysis and mutation screening. Ultrasound examinations were conducted at 16-21 weeks. Amniotic fluid sample was obtained by ultrasound-guided amniocentesis at 18 weeks of gestation.

RESULTSA large kindred affected with SPD was identified and characterized. With two short tandem repeat (STR) markers (D2S1238 and D2S1245) flanking the HOXD13 gene, the disease was mapped to 2q31. A heterozygous 27 bp expansion within the imperfect GCN triplet-repeat of exon 1, c. 184_210dup, was identified. The mutation resulted in a gain of 9 alanine residues between the 14th and 15th alanine of the normal 15-amino-acid-long polyalanine tract. On ultrasound examination, all fingers and toes of the fetus appeared to be normal. Linkage analysis and mutation detection confirmed that the fetus did not inherit the mutant allele from his affected mother.

CONCLUSIONHOXD13 gene mutation was responsible for the SPD phenotype in this family. Accurate prenatal diagnosis of SPD was achieved with combined ultrasound and molecular analysis.

OBJECTIVETo investigate the features of circulating plasmacytoid dendritic cells (pDCs) in patients with chronic hepatitis B for a better understanding of the immunopathogenesis of HBV infection.

METHODSFresh blood samples were collected from 20 patients with chronic hepatitis B (CHB) and from 15 healthy individuals who served as controls. pDCs were isolated from peripheral blood mononuclear cells (PBMCs) using immunomagnetic assay and detected by flow cytometry. Fresh PBMCs and isolated pDCs were stimulated in vitro using CpG ODN2216. The supernatants were measured for IFNa production using ELISA.

RESULTSThe peripheral pDCs frequency in CHB patients (0.192%+/-0.110%) was markedly lower than that in the healthy controls (0.287%+/-0.142%). After being pulsed with CpG ODN2216, the isolated pDCs produced lower levels of IFNa and expressed lower levels of CD80 and CD40 in the CHB patients when compared to those of the healthy controls. The level of IFNa was (972.6+/-705.5) pg/ml in the patients and (3 142.9+/-1 292.2) pg/ml in the controls. Moreover, the pDCs frequency was reversely correlated with serum ALT levels in these HBV infected patients.

CONCLUSIONThe reduced number and impaired function of circulating pDCs in patients with CHB may be related to their disease progression.

The purpose of this study was to investigate the efficacy of treatment with haploidentical donor's lymphocyte infusion(hiDLI) combined with interleukin-2 (IL-2) after transplantation of autologous peripheral blood stem cells mixed with haploidentical allogeneic bone marrow (mix-HSCT) for acute myeloid leukemia (AML). 49 patients diagnosed as AML were enrolled in this study. After preconditioning with TBI plus VEMAC regimen, all patients received mix-HSCT. Autologous peripheral blood hematopoietic stem cells were mobilized with chemotherapy-combined G-CSF, and haploidentical allogeneic bone marrow cells were not mobilized with G-CSF. 33 patients in test group were treated with hiDLI plus IL-2 for 1-8 times after hematopoietic reconstruction, 16 patients in control group received mix-HSCT only. All the patients were followed-up for more than 3 years. The results showed that all the patients obtained hematopoietic reconstruction, and no graft-versus-host disease (GVHD) was found. In two groups, the median time of absolute neutrophil count (ANC) ≥ 0.5×10(9)/L was 14 (12 - 18) and 14 (11 - 16) days, and WBC count ≥ 4.0×10(9)/L was 17 (16 - 22) and 18(17 - 20) days, Plt count ≥ 50×10(8)/L were 25 (24 - 29) and 25 (23 - 26) days. 9 patients in test group formed mixed chimerism (46XX/46XY) and sustained about 3 - 12 months; disease-free survival (DFS) was 63.6%, 3 patients in control group formed mixed chimerism (46XX/46XY), persistent about 3-6 months; DFS was 50.0%. It is concluded that treatment with hiDLI plus IL-2 after mix-HSCT for AML patients may increase DFS efficiently.

Objective To evaluate the clinical value of multi-slice spiral CT (MSCT)in the screening of coronary artery lesions in elderly patients with diabetes mellitus.Methods MSCT and coronary angiography(CAG)were performed in 136 elderly patients(68 patients with diabetes and 68 patients without diabetes).The number of diseased coronary segments and the plaque type (noncalcified,mixed and calcified)for each patient were determined.The characteristics of coronary lesions were compared between patients with and without diabetes.The sensitivity and specificity of MSCT were evaluated.Results More noncalcified and calcified plaques and few ermixed plaques were observed in patients with diabetes,compared with patients without diabetes(noncalcified plagues:10 cases or 14.7％ vs.4 cases or 5.9％;calcified plagues:47 cases or 69.1％ vs.39 cases or 57.4％)(P＜ 0.05).In addition,diabetic patients showed a significantly higher frequency of multivessel disease(P＜0.05).Furthermore,MSCT was able to clearly show stenosis and plaque type in the trunk and branches of the coronary artery,with a sensitivity of 91.0％,a specificity of 95.0％,a positive predictive value of 93％ and a negative predictive value of 96.0％.Conclusions Diabetes is associated with a higher risk of coronary artery disease.MSCT can effectively detect the characteristics of coronary artery disease in diabetic patients and is an effective,noninvasive,and safe screening method.

Objective:To understand the molecular pat hophysiology of hepatocellular carcinoma and pancreatic cancer.Methods: We studied novel gene expression by cDNA microarray method. The PCR pro ducts of 4 096 genes and 12 800 gene were spotted onto a kind of chemical-mater ial-coated-glass slide in array. Both the mRNAs from 5 cases of hepatocellular carcinoma and 3 cases of pancreatic cancer were reversely transcribed to cDNAs with the incorporation of fluorescent-labeled dUTP to prepare the hybridization probes. After hybridization, BioDoor4096 and BioDoor12800 cDNA microarray were scanned for the fluorescent intensity. Tumor invasion-related gene expression w as screened through the analysis of difference in gene expression profile.Results:Among 4 096 and 12 800 target genes, there were 15 genes who se expression level differed from normal and carcinoma tissues. Therefore, they might be associated with metastasis.Conclusion:Further analysis of these differentially expressed metastasis-associated genes will be helpful for understanding the molecular mechanism of malignant carcinoma.
