Objective To explore the application of continuing nursing model in life of puerperae with preterm infants and evaluate its effects.Methods Based on continuous nursing model of Ahmadi,puerperae's continuing nursing program was constructed.Randomized controlled trail design was used,and totally 110 puerperae in a hospital in Beijing were recruited from August 2016 to March 2017.The experimental group received continuing nursing intervention model,and the control group received routine nursing care.Parenting knowledge and psychological evaluation of the two groups were collected 3 days before discharge,1 month,3 months and 6 months after discharge.Results Ninety-eight puerperae completed the study.In the experimental group,the score of parenting knowledge was higher than that of the control group(P＜0.01),and the total score of mental health assessment and scores of depression and anxiety were lower than those in the control group (P＜0.05).Conclusion Puerperae's continuing nursing program based on the continuous nursing model of Ahmadi improved maternal ability and positive emotion,and promoted quality of life.

To investigate the suitable site environment for Atractylodes lancea, field trials in different niches was carried out, and the seedling growth, biomass and volatile oil components in different microhabitas was studied. The study found that the survival rate, plant height, volatile oil content of those which growing under the bamboo were significantly higher than those exposed in the open field. The survival rate understory was (76 ± 15.1) %, plant height understory was (77 ± 14. 8) cm and the summation of the four kinds of volatile oil content understory reached up to 4.09%; The same evaluation values of these indicators of the four faces in the open field respectively: survival rate is 30%, plant height was (77 ± 14.8) cm and the summation of the four kinds of volatile oil content was 2.24%. But, the yield of the understory (41 ± 22.3) g was significantly lower than those four faces in the open field (104.5 g) on the contrary. For the four open field towards, the yield of the east facing, which organic matter and other nutritional conditions were better than others, was significantly higher than those in the other facings. A. lancea was found to be an anti-poor and shading-like or growing in east facing slope herb through the correlation analysis of light, temperature, soil and leaf nutrients with seedling growth, biomass and volatile oil components. It also reminds us that the understory herb with high survival rate, low incidence, low management costs, and high medicinal ingredients, although it's production is not so high, but it can be improved by increased organic fertilizer. So the ecological planting patterns which can intercropping herbs with the forest was proposed.

OBJECTIVETo investigate the effect of ultraviolet ( UV) irradiation on the biocompatibility of Medpor.

METHODSThe Medpor implant, 2 mm in thickness, was divided into several pieces with the size of 1 cm x 1 cm. 12 Japanese big ear rabbits were divided into experimental (n=6) and control group (n=6). The 1 cm x 1 cm auricular cartilage defects were made in each rabbit ear. Then the defects were repaired with UV-treated Medpor implants in experimental group, and Medpor implants in control group. The levels of the total hemolytic complement (CH50) were measured 3 d hefore operation, and 1, 3, 7, 14, 21, 30, 60, 90 d after operation. The wound healing was observed. 90 d after operation, the animals were killed to get the specimens for gross observation and histologic examination. The change of CH50 level after operation was significantly different between the two groups ( P < 0.05) . The CH50 level was comparatively stable in experimental group. Compared with control group, the local inflammatory reaction was not obvious in experimental group. A great amount of tissue, including big vessels was growing into the mini-pores of Medpor, resulting a close combination between the implant and surrounding tissue.

CONCLUSIONIt suggests that ultraviolet irradiation can improve the biocompatibility of Medpor and promote the wound recovery.

An antibiotic-producing bacterium, which was numbered as 20 #-5, was separated from the soil in Chongqing. It was identified as the member of pseudomonas. Gram positive bacteria are badly suppressed by it. The antibiotic secreted by 20 #-5 can endure 100℃ for half an hour, and it can also go through the ultrafiltration membrane with pores of 0.22?m.

Ribavirin is a broad-spectrum antiviral agent and glycyrrhizin has activities of anti-inflammation, immunoregulation and anti-viral infections. To enhance antiviral efficacy and weaken side-effects of ribavirin, antiviral effects of the combination of glycyrrhizin and ribavirin were studied in the present study. Firstly, a mouse model of viral pneumonia was established by inoculation of influenza H1N1 virus. Protective effects of glycyrrhizin and ribavirin used alone or in combination against H1N1 virus infection in mice were evaluated based on the survival rate, lung index and virus titer in lungs of mice. Results showed that the combination of glycyrrhizin and ribavirin significantly inhibited the lung consolidation with a 36% inhibition ratio on the lung swell of infected mice. The combination of the two drugs exhibited synergetic effects on survival of infected mice. The combination of 50 mg · kg(-1) · d(-1) glycyrrhizin and 40 mg · kg(-1) · d(-1) ribavirin resulted a 100% protection for infected mice with a synergetic value of 36, which was significantly higher than the control group and each drug alone. This combination also resulted a significant drop of lung virus titer (P < 0.01), as well as inhibition on the production of proinflammatory cytokines IL-6 (P < 0.01), TNF-α (P < 0.01) and IL-1β (P < 0.05) induced by virus infection compared to the control. The treatment of ribavirin plus glycyrrhizin was more effective in influenza A infection in mice than either compound used alone, which suggested a potential clinical value of the combination of the two agents.

0.05).Conclusions ATP-TCA could be used to individualize chemotherapy by selecting agents for particular patients of cervical cancer.The expression of GST-? and TS protein might be useful biomarkers to predict the resistance to DDP and 5-FU in patients with cervical cancer.

In order to study the relationship between the expression of glutathione S-transferase (GST) in leukemic cells and the chemoresistance in patients with acute leukemia, the expressions of GST activity and GST mRNA were measured according to spectrophotometric assay based on the use of 1-choloro-2, 4-dinitro benzene and in situ hybridization. The results were studied in correlation with some clinical and pathological data. Results showed that: 1. There is no significant differences between activities of the enzyme with the different leukemia types according to the FAB classification. 2. GST activity and GST mRNA expression in the patients, both untreated and relapse, were (4.5 +/- 1.0) U, 33.3% and (7.9 +/- 15) U, 66.3% respectively. 3. In 56 patients, GST activity was 1.7 +/- 0.7, 5.9 +/- 2.0 and 9.3 +/- 1.7 U and GST mRNA expression was 13.3%, 29.7% and 76.6%, respectively, in CR, PR and NR groups. The lowest values of GST activity and GST mRNA expression were observed in those patients who achieved complete remission. The highest values of GST activity and GST mRNA expression were observed in those patients with no response to treatment. It was concluded that the expression of GST in patients with acute leukemia is closely related to the chemosensitivities clinically. Determinations of GST activity and GST mRNA are useful for predicting the chemosensitivities and the prognosis of the disease.

This study was aimed to investigate the effect of berberine on the proliferation and apoptosis of HL-60 cells, and the expression of vascular endothelial growth factor receptor 2 (VEGFR2) in HL-60 cells. Berberine (6 - 96 µg/ml) was added to the HL-60 cell line culture medium, the CCK-8 method was used to reveal the inhibitory effect on cell proliferation, the flow cytometry was used to determine the apoptosis rate and cell cycle in HL-60 cells treated with berberine. The expression of VEGFR2 mRNA and protein were examined by RT-PCR and Western blot respectively. The results showed that the berberine inhibited the proliferation of HL-60 cells and induced their apoptosis in dose- and time-dependent manners. With the increased concentration of berberine, the percentage of HL-60 cells in G(1) phase of cycle increased significantly, and the percentage of HL-60 cells in S phase decreased significantly. The expression of mRNA and protein of VEGFR2 decreased with the increased concentration of berberine. It is concluded that the berberine can inhibit HL-60 cell proliferation and induce HL-60 cell apoptosis. The expression of mRNA and proteins of VEGFR2 decreased after treatment with berberine.

In order to obtain the fungicides with minimal impact on efficiency of mycorrhizal symbiosis, the effect of five fungicides including polyoxins, jinggangmycins, thiophanate methylate, chlorothalonil and carbendazim on the growth of medicinal plant and efficiency of mycorrhizal symbiosis were studied. Pot cultured Glycyrrhiza uralensis was treated with different fungicides with the concentration that commonly used in the field. 60 d after treated with fungicides, infection rate, infection density, biomass indexes, photosyn- thetic index and the content of active component were measured. Experimental results showed that carbendazim had the strongest inhibition on mycorrhizal symbiosis effect. Carbendazim significantly inhibited the mycorrhizal infection rate, significantly suppressed the actual photosynthetic efficiency of G. uralensis and the most indicators of biomass. Polyoxins showed the lowest inhibiting affection. Polyoxins had no significant effect on mycorrhizal infection rate, the actual photosynthetic efficiency of G. uralensis and the most indicators of biomass. The other three fungicides also had an inhibitory effect on efficiency of mycorrhizal symbiosis, and the inhibition degrees were all between polyoxins's and carbendazim's. The author considered that fungicide's inhibition degree on mycorrhizal effect might be related with the species of fungicides, so the author suggested that the farmer should try to choose bio-fungicides like polyoxins.
