Objective To investigate the effectiveness of early minimal enteral feeding′s prevention and cure of feeding intolerance of very low birth weight infants (VLBWs).Methods A total of 45 VLBWs from the neonatal intensive care unit(NICU) of the second people′s hospital of Shantou,were included,from 2011 Jan to 2012 Dec. 23 infants in the intervention group which were hospitalized in 2012,received early minimal enteral feeding (MEF), while 22 infants in the control group which were hospitalized in 2011,received routine feeding .The incidence of feed-ing intolerance of the two groups was observed .Results The incidence rate of feeding intolerance was 21.74%(5 cases) in the intervention group and 72.73%(16 cases) in the control group.The incidence rate of feeding intol-erance of the intervention group was lower than that of the control group obviously and the difference was statistical significance(P<0.05).The time to achieve full enteral feeding of the intervention group [(28.22 ±1.97)days] was significantly shorter than that of the control group [(34.23 ±3.10)days](P<0.05).Conclusion An early MEF is beneficial to reduce the occurrence rate of feeding intolerance ,achieve full enteral feeding sooner ,decrease the length of hospital stay and improve the life quality of VLBWs .

OBJECTIVE:To optimize the emulsifying technology of Compound kuhuang cream. METHODS: The factors influencing the stability of the cream were optimized by orthogonal experiment with the thickness of the oil layer obtained after centrifugalization and substratification of cream as index. RESULTS: The optimum condition was obtained when the ratio of oil-phase stearine∶glyceryl monostearate∶lanoline∶liguid paraffin∶white vaseline was 4∶1∶2∶2∶1,the proportion of emulsifier was 4%, the hydrophile-lipophile balance (HLB) was 13 and the emulsion temperature was 80℃. CONCLUSION: The optimized emulsifying technology is stable and feasible and provides theoretic basis for the industrial production of Compound kuhuang cream.

AIM: To investigate the ability of leupeptin, TLCK and lactoferrin on tryptase release from human colon mast cells. METHODS: Human mast cells were dispersed from colon tissue with collagenase and hyaluronidase, and were challenged with stimulus for 15 min at 37 ℃. Tryptase concentrations were measured with a sandwich ELISA procedure. RESULTS: Leupeptin, TLCK and lactoferrin were not able to provoke significant tryptase release from human colon mast cells. But they were able to inhibit anti-IgE and calcium ionophore (CI)-induced tryptase release in a concentration-dependent manner. Preincubation of inhibitors of leupeptin and TLCK with cells for 20 min before challenging with anti-IgE failed to enhance their inhibitory actions. The extent of inhibition by leupeptin was increased when colon mast cells were preincubated for 20 min before CI being added. However, the same treatment failed to improve the action of TLCK. CONCLUSION: We found for the first time that leupeptin, TLCK and lactoferrin were able to inhibit anti-IgE and calcium ionophore-induced tryptase release from human colon mast cells, which may indicate a potential of a novel therapy for the treatment of inflammatory bowel disease or other mast cells-related diseases.

Many newly discovered interleukins have been implicated to play an important role in the pathogenesis of the allergic diseases, for example, human interleukin (IL)-17, a T-cell derived cytokine; interleukin (IL)-18, an interferon (IFN)-gamma-inducing cytokine; interleukin (IL)-23, produced by activated dendritic cells, and interleukin (IL)-25, a recently described T helper 2 (Th2) cell-derived cytokine. Understanding their characteristic and roles in diseases may help us to know better the mechanism of the allergic diseases and develop the strategy for treating the disease. [

Objective To explore the effect of different sleeping state and body position nursing on the surface temperature, heart and lung function, and development of premature infants. Methods A total of 160 cases of premature infants were selected as research objects, divided into active-prone group, active-supine group, quiet-prone group, quiet-supine groupwith random number tables. Each group on the basis of conventional nursing care was given the above position. Respiratory frequency (RR), heart rate (HR), oxygen saturation (SpO2), RR deviation, HR deviation and surface temperature were observed before and after nursing. After continuous nursing for 7 days, the differences of development indexes of each group were also observed. Results Surface temperature of forehead, right flank, right forearm, right leg were (36.4 ± 0.2), (36.4 ± 0.3), (35.6 ± 0.3),(34.4 ± 0.5)℃in group C, which were significantly higher than those in the other groups (F=2.89-3.31, P<0.05). HR, RR, HR-deviation, RR-deviation and its change value in group C were (128.5 ± 1.8) beats/min, (34.6 ± 2.2) beats/min, (9.1 ± 1.2)%, (212.5 ± 31.5)%, which were significantly lower than those in the other groups (F=4.61-4.96,P < 0.05), and SpO2 change value was 0.027±0.001, which was significantly higher than those in the other groups (F=3.65,P<0.05). Weight gain, the length growth, head circumference growth and upper arm around growth in group C and A in preterm infants after 7 days of continuous nursing were (118.6±6.3) g, (11.3±1.2) mm, (6.4±0.4) mm, (4.4± 0.2) mm and (110.3 ± 5.7) g, (11.0 ± 1.1) mm, (6.0 ± 0.5) mm, (4.2 ± 0.3) mm, which were significantly better than (74.5 ± 4.4) g, (6.9 ± 0.8) mm, (4.5 ± 0.7) mm, (3.2 ± 0.2) mm of active-supine group and (78.6 ± 4.9) g, (7.6±0.7) mm, (4.8±0.6) mm, (3.5±0.3) mm of quiet-supine group (F=3.57, 4.98,P<0.05). And the above indicators of quiet-prone group were higher than that of active-prone group (P<0.05). Conclusions The quiet-prone position can improve the heart and lung function and development of premature infants.
