Objective:To discuss the curative effect of phosphocreatine adjuvant treatment on neonatal hypoxic -ischemic myocardi-al lesion and its influence on serum IL-6 and myocardial enzyme .Methods:Totally 80 cases of newborns with hypoxic-ischemic myo-cardial lesion were divided into the observation group and the control group at random .The two groups were given the routine medical treatment, including maintenance of ventilation , warmth, water-electrolyte and acid-base balance, heart rate, blood pressure, nutrition support and etc, while the newborns in the control group were additionally given 250 mg· kg-1 1,6 diphosphate (FDP), ivgtt bid, for 10 days, while those in the observation group , were additionally given 1.0g phosphocreatine dissolved in 100 ml 0.9% normal saline (NS) on the basis of the treatment of the control group , ivgtt qd, for 10 days.The clinical curative effect and security were observed and the changes of serum IL-6 and myocardial enzyme in the two groups were compared .Results: The levels of LDH, CK, CK-MB and serum IL-6 in the two groups were obviously declined when compared with those before the treatment (P<0.05 or P<0.01), and the declining rate of the observation group was higher than that of the control group (P<0.05).The total clinical efficiency of the ob-servation group was higher than that in the control group after the medical treatment (P<0.05), and no serious untoward effect ap-peared in the two groups during the medical treatment .Conclusion: Phosphocreatine has significant curative effect on neonatal hy-poxic-ischemic myocardial lesion , which can effectively improve myocardial function of newborns and reduce myocardial enzyme and se -rum IL-6 levels.

Background and purpose: NF-?B is activated by tumor necrosis factor,some chemotherapeutic agents,and ionizing radiation.The activation of NF-?B could result in inhibition of apoptosis.NF-?B,regulated by PDTC(pyrrolidine dithiocarbamate),is a specific inhibitor of NF-?B.The purpose of our study was to explore the impact of inhibiting expression of NF-?B on radiation-induced apoptosis of uterine cervix cancer HeLa cells.Methods:Inhibition of NF-?B in HeLa cells was performed by treatment with 100 ?mol/L PDTC for 2 hours.Cells were irradiated at 0,2,4 and 6 Gy with or without PDTC.The expression of NF-?B in nuclear was determined by western blot,and apoptosis was evaluated by using the TUNEL assay.Cell proliferation was evaluated by using MTT assay.Results:NF-?B activation was induced by radiation and inhibited by PDTC.Inhibition of radiation-induced NF-?B activation resulted in inhibiting cell proliferation(P

In this paper, LM35 tempeture sensor is tested and shows good linear characteristics between 30 ℃ and 60 ℃, which provides a theoretical basis for making digital thermometer. A/D converting chip and 89c51 single chip micro -processor are employed in this digital body thermometer based on LM35. It possesses such advantages as low cost, high accuracy and excellent stability.

The sequences of 5.8S rDNA and the flanking internal transcribed spacers (ITS1 and ITS2) were sequenced from hypha, fruit body and sclerotia of Grifola umbellata and its companion fungus. Their ITS sequences similarity was 99.36%. The results suggested that G. umbellata was closely related to its companion fungus.

Leydig cells, located in the loose interstitial tissue of seminiferous tubules, are the major site for androgen synthesis and secretion, and play an important role in the reproductively and fertility of males. The dysfunction of Leydig cells may lead to various male diseases, such as primary hypogonadism, cryptorchidism, and hypospadias. This review outlines the recent findings concerning the generation, development and regulation of Leydig cells.

Objective: To observe the influence of trichostatin A (TSA) on the apoptosis of colonic cancer cell line HT-29 cells and expression of HIF-1α in HT-29 cells under hypoxia in vitro. Methods: HT-29 cells were treated with TSA(100, 200, 400, 600, 800 nmol/ L for 12, 24, 48, and 72 h. Cells in the control group were treated with the same volume of DMSO. MTT assay was used to investigate the survival of cells in each group. Annexin V and TUNEL were used to determine the apoptosis rate of HT-29 cells. RT-PCR and Western blotting were used to study the expression of HIF-1α mRNA and protein under hypoxia (37°C, 1% O2). Results: MTT assay demonstrated that cell viability decreased significantly in TSA-treated group compared to control group(P<0.05), and the inhibitory effect of TSA was in a dose- and time-dependent manner. Annexin V and TUNEL showed that TSA induced early apoptosis of HI-29 cells; the apoptosis rates in TSA treatment groups (200, 400, 600, and 800 nmol/L) were significantly higher than that of control group(P<0.05). TSA suppressed protein expression of HIF-1α under hypoxia in a dose-dependent manner but had no influence on mRNA expression of HIF-1α. Conclusion: TSA can induce apoptosis of HI-29 cells and inhibit their proliferation through suppressing expression of HIF-1α at protein level under hypoxia condition.

The endophytic fungi with plant growth promoting effects were screened by co-culture of each endophytic fungus and seedlings of Dendrobium officinale. Anatomical features of the inoculated roots were studied by paraffin sectioning. Morphological characteristics and rDNA ITS1-5. 8S-ITS2 sequences were applied for the taxonomy of endophytic fungi. The results showed that 8 strains inoculated to D. officinale seedlings greatly enhanced plant height, stem diameter, new roots number and biomass. According to the anatomical features of the inoculated roots, each fungus could infect the velamina of seedlings. The hyphae or pelotons were existed in the exodermis passage cells and cortex cells. The effective fungi could not infect the endodermis and vascular bundle sheath, but which was exception for other fungi with harmful to seedlings. Combined with classic morphologic classification, 2 effective strains were identified which were subjected to Pestalotiopsis and Eurotium. Six species of fungi without conidiophore belonged to Pyrenochaeta, Coprinellus, Pholiota, Alternaria, Helotiales, which were identified by sequencing the PCR-amplified rDNA ITS1-5. 8S-ITS2 regions. The co-culture technology of effective endophytic fungi and plant can apply to cultivate the seedlings of D. officinale. It is feasible to shorten growth cycle of D. officinale and increase the resource of Chinese herbs.
