OBJECTIVETo investigate the clinicopathological and biological features of micrometastasis in early gastric cancers.

METHODSEleven cases of early gastric cancer with micrometastasis (micrometastatic, MM group) and 46 cases of early gastric cancer with lymph node metastasis (control group) were included in the study. Immunochemical staining of ssDNA, bcl-2, p53, E-cadherin, Ki-67, CD34 was performed. The superficial lesions, invasive fronts and lymph nodes were examined in both groups.

RESULTSPositive rate of ssDNA at the superficial lesions in MM group was higher than that in control group. In MM group the positive rate of ssDNA in micrometastasis was higher than that at invasive fronts and in lymph nodes. Positive rate of bcl-2 at the superficial lesions in micrometastasis was higher than that at invasive fronts and lymph nodes. Positive rate of c-myc at the superficial lesions in MM group was higher than that in control group. Positive rate of E-cadherin and the percentage of microvascular areas at the lymph nodes in MM group was lower than those in control group. Proliferative ability of cancer cells at superficial lesions and lymph nodes in MM group was lower than those in control group. Lymph nodes <3 mm in micrometastasis accounted for 27.3%.

CONCLUSIONThe pathological and biological features of micrometastasis in early gastric cancer show low positive rate of ssDNA, E-cadherin, Ki-67 and low percentage of microvascular areas at the lymph nodes.

Objective To investigate the mutations of pedocyte molecules in patients with late onset familial focal segmental glomerular sclerosis (FSGS). Methods Thirty-one pedigrees of late onset familial FSGS in Department of Nephrology, Shanghai Ruijin Hospital from Sep 1997 to Oct 2007 were enrolled in this study. The diagnosis standard of familial FSGS was as follows:(1) the age of presentation was more than 12 years old. (2) in one pedigree, two or more individuals were proven as FSGS by renal biopsy, or at least one was proven to be FSGS by renal biopsy, the others presented renal insufficiency or pmteinuria without precise causes. One hundred unrelated healthy people were screened as control group. Genomic DNA extracted from peripheral blood cells were amplified by PCR and then sequenced for mutations of NPHS2, ACTN4 and TRPC6. Results A novel missense heterozygotic mutation L316P of ACTN4 was identified inone pedigree. The mean onset age of the affected members of this pedigree was (38.7±7.4) years old and their kidney injury progress was slow. Proteinuria of the proband's brother was not improved by immunosuppressor. All 3 affected members of this family had such heterozygotic mutation. A novel missense heterozygotic mutation Q889K of TRPC6 was found in another pedigree. The mean onset age of the affected members in this pedigree was (38.0±4.2) years old. Three members presenting renal disease in this family all had such heterozygotic mutation but with different clinical manifestations. A quiescent mutation G467G of TRPC6 was also identified. Above variants were not found in healthy controls. No NPHS2 mutation was found to cause familial FSGS in these pedigrees. Conclusions A novel mutation L316P of ACTN4 and a new mutation Q889K of TRPC6 are identified in Chinese patients of late onset familial FSGS. No NPHS2 mutation is found to induce FSGS in these pedigrees.

The high price of the reference substances is an obstacle for the HPLC analysis of Lonicerae Japonicae Flos. To solve this problem, a new method based on the standard reference extract (SRE) was proposed. In this study, the extract of Lonicerae Japonicae Flos was calibrated, and the long-term stability was investigated. Different concentration solutions of SRE were prepared for establishment of the calibration profiles, and 6 organic acids were determined. T-test was used for the comparison of the determination results via reference substances and SRE, and the results demonstrated that there is no significant difference between the two methods. The presented method can be used for the quality control of Lonicerae Japonicae Flos, and will also offer reference to resolve similar problems.

The rol genes on pRiA4 plasmid of Agrobacterium rhizogenes are potent genes that promote secondary metabolism. Molecular breeding of Atropa belladonna can be conducted by introducing rol genes to increase tropane alkaloids (TAs) content in A. belladonna. In this study, the rolB gene was overexpressed in A. belladonna plants to study the effect of rolB gene on the biosynthesis of TAs. The phenotype, TAs content and expression levels of key enzyme genes in the pathway of TAs biosynthesis of transgenic A. belladonna were analyzed. The results showed that transgenic A. belladonna had developed root system, enlarged leaves, increased leaf fresh weight, deepened leaf color, enlarged flowers, changed flower shape, reduced pistil height and decreased pollen vitality. The content of TAs in the stems of transgenic A. belladonna was significantly higher than that of the control, and the contents of scopolamine, anisodamine, hyoscyamine can reach 2.11-2.91, 1.23-2.37 and 4.88-5.20 times of the control, respectively. Compared with the control group, the expressions of key enzymes putrescine N-methyltransferase (PMT), type III polyketide synthase (PYKS), tropinone reductase I (TRI), aromatic amino acid aminotransferase 4 (ArAT4), UDP-glycosyltransferase 1 (UGT1) and hyoscyamine 6-β-hydroxylase (H6H) in the TAs biosynthesis pathway were up-regulated, and the expression of tropinone reductase II (TRII) as a metabolic shunting gene was down-regulated. The results indicated that rolB gene enhanced TAs synthesis ability in roots and accumulation in stems of A. belladonna by enhancing metabolic flow of TAs synthesis pathway and weakening the metabolic shunt of competing pathway. This study laid a foundation for molecular breeding of A. belladonna with high-yield TAs content using rolB gene.

OBJECTIVETo evaluate the efficacy and safety of using Jiangzhi Tongluo Soft Capsule (JTSC) combined with Atorvastatin Calcium Tablet (ACT) or ACT alone in treatment of combined hyperlipidemia.

METHODSA randomized, double blinded, parallel control, and multi-center clinical research design was adopted. Totally 138 combined hyperlipidemia patients were randomly assigned to the combined treatment group (A) and the atorvastatin treatment group (B) by random digit table, 69 in each group. All patients took ACT 20 mg per day. Patients in the A group took JTSC 100 mg each time, 3 times per day. Those in the B group took JTSC simulated agent, 100 mg each time, 3 times per day. The treatment period for all was 8 weeks. Serum levels of triglyceride (TG), total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), and high density lipoprotein cholesterol (HDL-C) were observed before treatment, at week 4 and 8 after treatment; and safety was assessed as well.

RESULTSAt week 4 and 8 after treatment serum TG decreased by 26.69% and 33.29% respectively in the A group (both P < 0.01), while it was decreased by 25.7% and 22.98% respectively in the B group (both P < 0.01). At week 8 decreased serum TG was obviously higher in the A group than in the B group (P < 0.05). Compared with before treatment, serum levels of LDL-C and TC levels decreased significantly in the two groups (all P < 0.01). There was no statistical difference in the drop-out value and the drop-out rate of serum LDL-C and TC levels (P > 0.05). At week 8 the serum HDL-C level showed an increasing tendency in the two groups. No obvious increase in peptase or creatase occurred in the two groups after treatment.

CONCLUSIONJTSC combined with ACT could lower the serum TG level of combined hyperlipidemia patients with safety.

The experience with the umbilical cord blood (UCB) stem cells for unrelated transplantation from our 3 000 UCB storage was described. UCB, collected from closed blood bags, were mixed with hydroxyethyl starch for nucleated cell (NC) enrichment. After finishing CD34 analysis, culture of hematopoietic progenitors (CFU-GM and CFU-GEMM) assays, microbial culture, HLA Class I (A, B) serology and class II (DR) low resolution SSP typing, cord blood units are stored in the liquid nitrogen for clinical applicatoin. Cord blood contained an average of nuclear cell (NC) (1.2 +/- 0.6) x 10(9), CD34(+) cells (3.0 +/- 3.7) x 10(6), CFU-GM (1.1 +/- 0.7) x 10(6) and CFU-GEMM (1.1 +/- 1.2) x 10(6) for storage and the recovery rates were 91%, 88%, 85% and 82%, respectively. The recovery rates for red blood cell and Hb were (39 +/- 9)% and (40 +/- 8)%, respectively. The storage volume was (35.1 +/- 7.1) ml in a 50 ml storage bags. The mean time from collection to processing of 15 hours (range 4 - 24 hours) had no influence on cell viability. The cell viability before processing is more than 95% and 92% after UCB thawing. The recovery rates of NC, CD34(+) cells and CFU-GM post-thawing were 96%, 90% and 91%, respectively. There were no HIV antibody (HIVAb) positive in all of UCB units. For an incidence of processed samples, infection with syphilis, HBsAg, HBcAb, HCVAb, CMV, bacterial contamination and abnormal hemoglobin were 0.1%, 0.8%, 3.2%, 0.2%, 87.1%, 1.2% and 0.1%, respectively. More than 3 HLA loci matched can be found for random patients in our cord blood bank and 6 HLA loci matched have 5%. For transplantation with nucleated cell counts of > 2.7 x 10(7) cells/kg, our cord blood bank will be able to provide all of the umbilical cord blood stem cell samples for children and 50% of units can be used for some of adult recipients transplantation in the country. It is concluded that: (1) The large cord blood banking for 20 000 UCB storage is feasible in China. (2) Our system of whole procedure and methods is functionable for supplying qualified cord blood units in transplantation. (3) The volume for collection is critical to the yield of CD34(+) cells or hematopoietic progenitor cells, however cord blood NC is also important and proportional with CD34(+) cells. Only the units containing more than 8 x 10(8) cells and more than 60 ml of cord blood can be in the procession for storage.
