Objective is designed to observe the effect of the low molecular protein "SL Hong-Xin Blood-Increasing Capsules" on human iron deficiency anemia. Altogether 110 school children, 7 - 12 years old, with iron deficiency anemia (Hb < 120 g/L) were enrolled in this trial and were randomly and evenly divided into two groups. In the treatment group (n = 55), the "SL Hong-Xin Blood-Increasing Capsules" were orally adminitered for 30 days, two capsules at one time and two times a day, whereas in the control group (n = 55) blank capsules were given to the children in the same way as in the treatment group. Before and at the end of the trial period, peripheral blood samples were taken from fringers of the children to determine Hb content, hematocrit percentage, and free protoporphyrin content in red blood cells. Results showed that after trial the Hb content was (15.9 +/- 9.6) g/L in the treatment group, while that of the control group was only (5.3 +/- 4.3) g/L (P < 0.001). The hematocrit percentage markedly increased (P < 0.001) and protoporphyrin level markedly decreased (P < 0.001). In conclusion the active ingredient of "SL Hong-Xin Blood-Increasing Capsules" is low molecular protein iron, which is markedly effective for elevating Hb content and hematocrit percentage, and effective for decresing protoporphyrin content of children with iron deficiency anemia. Hence, the capsules could be used to improve nutritional anemia in children based on the "Functional Evaluation Procedure and Test Methods For Health-Care Food".

OBJECTIVEThe effect of vascular endothelial growth factor(165) (VEGF(165)) on intracellular free magnesium ([Mg(2+)](i)) and the relationship between Mg(2+) and angiogenesis in human umbilical vein endothelial cells (HUVECs) were investigated in this study.

METHODS[Mg(2+)](i) in HUVECs loaded with fluorescent magnesium indicator mag-fura-2 were quantitatively detected with the use of intracellular cation measurement system. HUVECs were obtained from normal fetus and cultured in M199 with 0.2 fetal bovine serum. The angiogenesis effects of VEGF(165) were observed in presence of 0 mmol/L, 1 mmol/L or 2 mmol/L of extracellular Mg(2+).

RESULTSVEGF(165) significantly increased [Mg(2+)](i) in a dose-dependent manner independent of extracellular Mg(2+), Na(+) and Ca(2+) and this effect could be blocked by pretreatment with VEGF(165) receptor-2 (KDR) inhibitor (SU1498). The angiogenesis induced by VEGF(165) was significantly inhibited cells with 0 mmol/L extracellular Mg(2+), the angiogenesis effects of VEGF(165) were similar in cells with 1 mmol/L and 2 mmol/L extracellular Mg(2+) and these effects could be blocked by SU1498.

CONCLUSIONSThese results suggest that the [Mg(2+)](i) increase induced by VEGF(165) originates from intracellular Mg(2+) pools and promotes angiogenesis via KDR-dependent signaling pathways.

OBJECTIVE: To analyze the distribution and pathogenicity of 27 HPV(Human papillomavirus)subtypes in cervical lesions.METHODS: A retrospective analysis was carried out in 5735 patients with cervical lesions admitted to the First Affiliated Hospital of Wenzhou Medical University from January 2015 to July 2017,including 997 cases of cervicitis,1568 cases of LSIL(low-grade squamous intraepithelial lesion),2576 cases of HSIL(high-grade squamous intraepithelial lesion)and 594 cases of cervical cancer. The HPV subtypes,histopathological results and ages were obtained for analysis.RESULTS: The positive rates of HPV in cervicitis group,LSIL,HSIL group and cervical cancer group were 57.0%,78.3%,90.5%,and 93.9%(P<0.05)respectively. The five most prevalent HPV types in cervicitis and LSIL group were 52,53,16,58 and 18;in HSIL and cervical cancer they were 16,52,58,33 and 18. The cumulative attribution rates of HPV16,18,58,52,33,31 and 45 in cervicitis,LSIL,HSIL and cervical cancer were 22.2%,38.4%,68.4% and 80.1%,respectively. The incidence of cervical cancer after HPV16,31 and 45 infection was 27.7,14.3 and8.2 times higher than that of cervicitis. Among the 36 cervical cancer tissue samples with negative HPV,8 cases were detected positive by HPV E6/E7 DNA detection.CONCLUSION: HPV16,18,58,52,33,31 and 45 have a high prevalence,cumulative attribution rates and risk values in patients with squamous intraepithelial lesions and cervical cancer. The above-mentioned subtypes of HPV should be included in the prevention and screening of cervical cancer.HPV E6/E7 DNA detection may be a reliable assay for HPV-based screening for prevention of cervical cancer.

OBJECTIVETo investigate the phenotypes and functions of cord blood dendritic cells of fetuses whose mothers are patients with chronic hepatitis B.

METHODSPeripheral blood and cord blood mononuclear cells (PBMC) were isolated from whole blood by density gradient centrifugation with Ficoll-Hypaque. The adherent cells were cultured in AIM-V medium containing recombinant human IL-4, TNF-alpha and GM-CSF. On day 9, mature DCs (mDC) were harvested and used for phenotype analysis. The amounts of IL-12 which dendritic cells produced were measured. The dendritic cells that were studied and compared were from cord blood of fetuses of both CHB positive and negative mothers and from CHC adult peripheral blood.

RESULTSThe expression rate of CD80 and CD83 of chronic hepatitis B mother cord blood dendritic cells was low compared with that of the healthy cord blood, healthy adult peripheral blood, and chronic hepatitis B adult peripheral blood, P < 0.05. The amount of IL-12 produced by chronic hepatitis B mother cord blood dendritic cells was lower than that of healthy cord blood, healthy adult peripheral blood, chronic hepatitis B adult peripheral blood (P < 0.05). The T lymphocyte proliferation inducing ability of dendritic cells of healthy adult peripheral blood was higher in inducing cord blood T lymphocytes proliferation, which was greater than that of the healthy adult peripheral blood in inducing adult T lymphocytes and was greater than that of the healthy cord blood dendritic cells in inducing cord blood T lymphocytes, which was greater than that of the healthy cord blood in inducing adult T lymphocytes, which was greater than that of chronic hepatitis B mothers in inducing cord blood T lymphocytes, which was greater than that of chronic hepatitis B mother cord blood in inducing adult T lymphocytes.

CONCLUSIONThe maturation and functioning of CHB mother cord blood dendritic cells were lower than those of healthy cord blood, healthy adult peripheral blood and CHB adult peripheral blood.

OBJECTIVETo explore the possible immuno-regulating mechanism of action of Chinese drugs in different combinations (assembled depending different therapeutic principles) through observing the effects of Feiliuping ointment (FLP) and its disassembled prescriptions on dendritic cells (DC) in blood, spleen and tumor in mice with transplanted Lewis lung cancer (LLC).

METHODSPercentages of DC in blood, spleen and tumor of mice with transplanted LLC treated by FLP and its disassembled prescriptions were estimated, and the S-100 protein expression in tumor tissue was detected by immunohistochemical method.

RESULTSThe percentage of DC (per thousand) in tumor bearing mice was 0.43 +/- 0.26 in peripheral blood, and 0.32 +/- 0.16 in spleen, significantly lower than those in normal mice 4.68 +/- 0.90 and 3.68 +/- 1.58, P<0.01); and S-100 protein expression in tumor was weakened. After FLP treatment, the percentages of DC (per thousand) in tumor bearing mice were increased to 2.55 +/- 0.29 in peripheral blood and 2.70 +/- 0.63 in spleen (P<0.01), with the S-100 protein expression in tumor tissue up-regulated significantly (P<0.01). Study on different assembled prescriptions of FLP showed that the qi supplementing components of FLP displayed the optimal actions.

CONCLUSIONFLP, a Chinese herbal prescription made depending on Chinese medicine therapeutic principle of strengthening body resistance and consolidating constitution, has an obvious anti-tumor effect, to improve the immunological anti-tumor function of organism by promoting the amount and expression of DC might be the possible intrinsic mechanism.

OBJECTIVEVarious models of experimental myocardial ischemia were set up to ovbserve the Yixinton's protection against ischemia.

METHODModels of experimentally acute myocardial ischemia were made by ligature or medication (pituitrin or isoprenaline) to check the indices of ECG, hemodynamics, and morphology.

RESULTA dosage of Yixintong tablets 100 mg/kg, 200 mg/kg was given to rats by gavage; the rats had undergone a thirty-minute ligatute of coronary lef anterior descending branch, and used as a model of ischemic reperfusion. The observations showed that Yixintong tablets exerted a recovery effect on heart rate, blood pressure, internal pressure of left ventricule and its peak/trough rate (+/- dp/dtmax), and ST segment (electrocardiogram). The tablet markedly reduced the myocardial infarct size of the coronary-ligatured rats. The tablet benefited the rats with pituitrin(iv)- or isoprenaline(ip)-induced acute myocardial ischemia to reverse any ST deviation and T-wave fall.

CONCLUSIONYixintong has a protective and therapeutic action to the experimental myocardial ischemia.
