OBJECTIVETo evaluate the status of complementary feeding frequency (CFF) for infants and young children in southwestern China.

METHODSA total of 3644 infants and young children aged 6 - 24 months from urban and rural areas of Chengdu, Kunming and Guiyang were selected by stratified random cluster sampling from March to June in 2011. Data of CFF in the recent one month were collected through the questionnaires, and assessed quantitatively by a new comprehensive evaluation system. Level and distribution characteristics of CFF for infants and young children among different month groups in urban and rural areas were analyzed.

RESULTSAverage CFF score was 8.1 ± 3.1, and the score for all was 54.1% of total score (15 points). The average score of urban and rural groups was 8.9 ± 3.0 (59.3% of total score) and 7.4 ± 3.0 (49.1% of total score) respectively (t = 15.60, P < 0.05). Ratio of ≥ 80.0% of total CFF score was 12.2% (443/3644) for all. The rate of urban and rural group was 18.0% (324/1796) and 6.4% (119/1848) respectively (χ(2) = 136.64, P < 0.05). Average CFF score in 6 - 8, 9 - 11 and 12 - 24 months groups was 7.0 ± 2.9 (46.4% of total score), 8.1 ± 3.0 (54.1% of total score) and 9.0 ± 3.0 (60.1% of total score) respectively (F = 148.27, P < 0.05). The CFF score increased with months growing.

CONCLUSIONStatus of CFF for infants and young children in southwestern China is generally inadequate, with differences between urban and rural groups. This problem is more serious in early month infants and rural areas and should be emphasized and improved.

OBJECTIVETo investigate regulation function of anodonta glucan HBP-A on chondrocytes through Wnt pathway in vitro.

METHODSRat chondrocytes were cultured and differentiated induced with IL-1beta (10 ng/ml) in vitro. Chondrocytes were divided into five groups:IL-13 group,IL-1beta + IWP-2 (5 microM,Wnt pathway inhibitor) group, IL-1beta + HBP-A (0.3 mg/ml) group and IL-1beta + IWP-2 + HBP-A group. Wnt-3a, beta-catenin (24 h,48 h,72 h) and MMP-13(72 h) genes expression were detected by Rt-PCR, while beta-catenin, MMP-13, Sox-9 and coll-II (48 h) protein expression were measured by Western-blot.

RESULTSAfter induction of IL-1beta, gene expression of Wnt-3a, beta-catenin and MMP-13 were increased,so were the protein expression of beta-catenin and MMP-13. In contrast,protein expression of Sox-9 and Coll-II were declined. Following addition of HBP-A, Wnt-3a, beta-catenin and MMP-13 were shown as induction of IL-1beta, but protein expression of Sox-9 and Coll-II were upgraded. Combining HBP-A with IWP-2 led to the lowest level in Wnt-3a, beta-catenin gene and beta-catenin protein expression and highest expression of Sox-9 protein.

CONCLUSIONHBP-A could not only delay the differentiation of chondrocytes through downgrading the signal expression of Wnt/beta-catenin,but also adjust the expression of Wnt-3a, beta-catenin and Sox-9 when combinated with the Wnt inhibitor.

To investigate the effects of interferon alpha-2b on proliferation and apoptosis in HL-60 cells, HL-60 cells were cultured in different concentrations of IFN alpha-2b. The morphologic changes were observed by Wright's and acridine orange (AO) and ethidium bromide (EB) staining respectively. Inhibition of proliferation was detected by MTT. Expression of CD13(+) was checked by indirect fluoroimmunoassay. The results showed that apoptosis rate of HL-60 cells assayed by the above-mentioned two methods was (51 +/- 2)% and (78 +/- 3)% respectively and OD(570) values of proliferation inhibited were 1.8 +/- 0.1 and 1.0 +/- 0.1 respectively when the concentrations of the IFN(alpha-2b) were 500 and 10,000 U/ml in culture for 48 hours. Morphology and count of CD13(+) cells were changed. CD13(+) cell expression rate was (62 +/- 2)% and (30 +/- 3)% respectively when the concentrations of the IFN(alpha-2b) were 500 and 10,000 U/ml in culture for 48 hours. It is concluded that IFN(alpha-2b) can enhance the apoptosis of HL-60 cells, inhibit their proliferation, promote their maturation and differentiation.

OBJECTIVETo explore the reductive effect of ornidazole on sperm motility in rats and its mechanism of action.

METHODSTwenty rats were randomly divided into three groups, a low dosage group (LD group, n = 5), a high dosage group (HD group, n = 8) and a normal control group (n = 7). Ornidazole (200 mg/kg, 400 mg/kg) was given to the LD and HD groups, and 0.5% carboxymethylcellulose sodium (CMC) administered to the normal control, all for 20 consecutive days. Immediately after, sperm density, motility and the morphological changes of the testis and epidiclymis were measured, and the concentrations of lactate dehydrogenase (LDH), alpha-glycosidase, malondialdehyde (MDA) and fructose in the testis and epididymis tissues were monitored.

RESULTSCompared with the normal control, there were no obvious changes in sperm density (P > 0.05), but a significant decrease in sperm motility in the LD and HD groups (P < 0.01), and the concentration of LDH obviously declined (P < 0.01) while that of MDA distinctly increased in the HD group (P < 0.05).

CONCLUSIONSpermatogenic cells could be damaged by the increase of inhibiting MDA, while sperm motility could be decreased by inhibiting energetic transferase or non-protein substance in the epididymis. This might be one of the mechanisms of ornidazole on weak sperm models in rats.

OBJECTIVETo evaluate the effect of titrated target-controlled infusion with propofol and remifentanil on anesthetics consumption and anesthesia depth in patients undergoing elective laparoscopic colorectal surgery.

METHODSSixty ASA I-III patients for elective laparoscopic colorectal surgery were enrolled. Titrated target-controlled infusion (TCI) with propofol and remifentanil was performed. Plasma concentration of the drugs was administered by titrated method to maintain bispectral index (BIS) in the range of 40-60 with systolic blood pressure (SBP) fluctuation within 20% of the basic value. BIS, SBP, plasma concentration of propofol and remifentanil were recorded at different time points. Awareness during operation was inquired postoperatively.

RESULTSDuring the entire anesthesia period, the blood pressure was stable and BIS was maintained less than 60. There was no awareness during operation. The plasma concentrations (95% confidence interval) for TCI of propofol and remifentanil were 2.55-2.65 mg/L and 4.09-4.26 μg/L respectively when existing surgical stimulation during anesthesia, and the plasma target concentration of propofol was lower than the recommended dosages.

CONCLUSIONTitrated target-controlled infusions with propofol and remifentanil for elective laparoscopic colorectal surgery can maintain proper anesthesia depth and reduce the drug consumption.

OBJECTIVETo explore in-vivo targeted imaging techniques for liver cancer detection using quantum dots (QDs) labeled probes in a nude mouse model of human hepatocellular carcinoma.

METHODSMercaptoacetic acid (MAA) modified QDs were linked to mouse-anti-human alpha-fetoprotein (AFP) monoclonal antibody to form water soluble QD-AFP-Ab probes, which were validated by spectra analyses and transmission electron microscope. The probes were firstly used to detect AFP antigen in human hepatocellular carcinoma cell line HCCLM6 in-vitro by one-step immunofluorescence method. In-vivo tumor xenografts and lung metastases models were then established by inoculation of HCCLM6 cells subcutaneously and into the tail vein of nude mice, respectively. QD-AFP-Ab probes were injected into the tail vein of the tumor bearing mice for live animal fluorescence imaging. Spectra of tumor and normal tissue were analyzed under illumination of Ti: sapphire laser. Serum levels of alanine amino transferase, aspartate amino transferase, blood urea nitrogen and creatinine were determined by conventional biochemical analysis. The liver, spleen, lungs, kidneys, heart and brain of the experimental nude mice were investigated for nonspecific uptake of the probes by confocal microscope.

RESULTSThe QD-AFP-Ab probes had broad excitation spectra and high fluorescence intensity. They could specifically and efficiently recognize AFP antigen in hepatocellular carcinoma cells. Tumor targeting imaging using these probes were successful without any acute toxicity to the experimental animals. Spectra analysis showed that the probes per field were lower in the centre than the periphery of the tumor. Non-specific uptake of QD-AFP-Ab probes occurred mainly in the liver, spleen and lungs.

CONCLUSIONSQD-AFP-Ab probes have good optical properties and biocompatibility for in-vivo targeted imaging of hepatocellular carcinoma. Such approach promises to be highly desirable for molecular targeted research of liver cancer.

OBJECTIVESTo screen and clone the genes encoding hepatocellular carcinoma associated tumor antigens.

METHODSA hepatocellular carcinoma cDNA express library was constructed with ZAP vector and analyzed by serological analysis of recombinant cDNA expression library (SEREX) with sera from autologous and allogenous patients. Monoclonalized positive phage clones were converted into pBK-CMV phagemid forms by in vivo excision. The cDNA inserts were determined by restriction endonuclease digestion with EcoR I and Xho I. The cDNA inserts were sequenced and analyzed with bioinformatics. LIMS1 insert was cut from the clone HCL5-70 and constructed into pQE 31 express vector. The recombinant LIMS1 was expressed in M15 and analyzed with SDS-PAGE and Western blot.

RESULTSFourteen genes were cloned from autologous screening and eleven genes were obtained with allogeneous analysis. One gene, kinectin, was identified in both autologous and allogeneous screening. Eight of the total twenty-four genes were unknown for their functions; the other sixteen genes can be classified into eight groups according to their established or putative function. Recombinant LIMS1 was expressed in M15.

CONCLUSIONThe identification of hepatocellular carcinoma associated tumor antigens provides potential targets for immunotherapy of hepatocellular carcinoma patients and will help in the understanding of the carcinogenesis of hepatocellular carcinoma.
