A study on the clinical application of all-in-one-mixed and pre-mixed parenteral nutrition preparations / 中华普通外科杂志

ObjectiveTo evaluate the parenteral nutrition formula's character of all-in-one-mixed preparation and pre-mixed preparation applied for hospitalized patients in China.MethodsWe collected parenteral nutrition (PN) prescriptions in hospitalized patients with various diseases at dispensing centers of 6 hospitals in different areas of China. Statistic analysis was made by nutrients application, total liquid, nonprotein calories, total nitrogen, ratio of non-protein calories and total nitrogen, and ratio of glucose and fat. A comparison was made between all-in-one-mixed and pre-mixed preparation as to all the indices.Results The nutrients supply in all-in-one-mixed PN preparation, as well as in the pre-mixed PN preparations of 3 different energy degrees can meet the basic nutrition requirements of most patients. The total nitrogen supply in all-in-one-mixed PN prescriptions meets nutrition requirements in most patients, but the ratio of non-protein calories and total nitrogen[( 180-250) : 1]and the ratio of glucose and fat (0. 56-1.26)were significantly different from what a doctor would recommend[( 100-150) : 1, 1.0]. While the ratios in the pre-mixed PN preparation on 3 different energy degrees are more consistent with recommeded values,which are at 167 and 0. 8 respectively.ConclusionsAll-in-one-mixed and pre-mixed PN preparation have their own individual advantages and limits, and both of them can meet the requirements of most hospitalized patients. More attention should be paid to the nutrients proportion when doctors prescribe all-in-one-mixed PN preparations.

Identification of protective truncated domain of Fba anchored on the surface of group A streptococcus / 中华传染病杂志

Objective The truncated fibronectin-binding proteins A (Fba protein) were cloned and expressed, then animals were immunized with Fba protein and subsequently challenged with group A streptococcus (GAS) to further investigate protective antibodies induced by each domain and determine the most immunogenic domain. Methods Fba proteins, which were divided into four overlaps based on the structural domains, were truncated and expressed. The fba truncated genes were amplified by polymerase chain reaction (PCR) with SSI-9 of GAS as template, and cloned into prokaryotic expression plasmid pGEX-2T and expressed in E. coli BL-21. The products were confirmed by Western blot and purified by affinity chromatography column. Female BALB/c mice were immunized with the four truncated proteins respectively, with phosphate buffered solution (PBS) as control. The serum IgG of mice was detected by enzyme-linked immunosorbent assay (ELISA). After the third immunization, mice were challenged with fatal dose of GAS (M+ Fba+ ) to evaluate the protective rates in each group. The data were compared by analysis of variance and Fisher's exact test.Results Prokaryotic expression plasmids of pGEX-2T/FbaAl, pGEX-2T/FbaA2, pGEX-2T/FbaA3 and pGEX-2T/FbaA4 were successfully constructed and the four truncated proteins were expressed and purified successfully. Serum levels of IgG in each experimental group gradually increased with immunization with Fba protein more times. After the third immunization, the IgG titer against FbaA2 1290.2, P<0. 01). After GAS challenge, four out of eight mice were protected in FbaA2 protein group, while two out of eight mice in FbaAl protein, FbaA3 protein and FbaA4 protein groups,respectively (P<0. 05). Conclusions Four truncated Fba proteins are constructed and expressed successfully. Truncated FbaA2 protein could be able to induce strongest protective immune response.

Change of high mobility group box 1 and effect of drainage of intestine lymph fluid on rat gut barrier during intestine ischemia-reperfusion / 中华临床营养杂志

Objective To investigate the change of high mobility group box 1 ( HMGBI ) after intestine ischemia reperfusion (I/R) in rats, compare the effect of drainage of intestine lymph fluid on gut barrier, and ex- plore the possible mechanism of iachemia-reporfusion injury. Methods Thirty-two Sprague-Dawley (SD) rats (SPF grade) were randomly divided into4 groups with 8 rats in each group: blank group, sham group, intestine is-chemia-reperfusion (I/R) group, and intestine ischemia-reperfusion with drainage of intestine lymph fluid (I/R +drainage) group. Indicators of gut barrier function damage, translocation of endotoxin, and change of HMGB1 and cytokines were detected after intestine ischemia-reperfusion injury. Results The gut barrier function damage and levels of endotoxin, HMGBI, tumour necrosis factor-alpha ( TNF-α), interleukin-6 ( IL-6 ), interleukin-1 beta (IL-1β), and soluble intercellular adhesion molecule-1 (sICAM-1) were significantly lower in blank group and sham group than in I/R group and I/R + drainage group ( P < 0. 05 ). Compared with the intestine I/R + drainage group, the levels of endotoxin and cytokines were significantly higher in the intestine I/R group. The level of HMGB1 was slightly higher than that in the intestine I/R + drainage group, but such difference was not statistically significant ( P > 0. 05 ). lmmunohistochemical staining also revealed that the expression of HMGB1 was significant- ly higher in I/R group than in I/R + drainage group. Conclusions Intestine iachemia-reperfusion injury can lead to the injury of intestine mucosal barrier and increase HMGB1 level HMGB1 may deteriorate gut barrier function and increase the leveh of systemic cytokines. Drainage of lymph fluid can block the gut-lymph pathway and thus decrease the levels of endotoxin and cytokines in systemic circulation and attenuate intestine ischemia-reperfusion injury.

Development of one step RT-PCR technique for detection of H7 subtype avian influenza / 生物工程学报

According to 45 hemagglutinin (HA) gene sequences of H7 subtype of avian influenza virus (AIV), a pair of specific oligonucleotide primers was designed. We developed one step RT-PCR for detecting AIV subtype H7. Sensitivity to detection of allantoic fluid by one step RT-PCR reached 10(5.5) EID50/mL and detection of swab samples reached 10(3) EID50/mL. We simultaneity detected the tissue and swab samples infected with H7 subtypes AIV by one step RT-PCR and virus isolation method. The results showed that the sensitivity of the assay gave an excellent correlation with the conventional virus isolation method. H1-H15 subtypes of avian influenza and other avian diseases were detected by the one step RT-PCR. The results showed the assays were high specific, without cross-reaction with other subtypes or other avian diseases. Development of one step RT-PCR will provide effective technical support for the rapid diagnosis and surveillance of molecular epidemiology of AIV subtype H7.
