Objective To evaluate the clinical effect of the enteral nutrient(Pediasure) on making improvements in nutritional status of children with anorexia.Methods Thirty children were treated with pediasure for 2 months, twice a day, and height(Ht),weight(Wt),AG,TSF,SSF,ASF,RBC,Hb were measured before and after treatment and their appetites,alimentary canal reactions were recorded.Results Compared with the effects after 2 months, the average Ht,Wt,AG,SF all increased, and there was significant difference between pretreatment and after treatment(P0.05). All of the 30 children had no adverse reactions during treatment.Twenty-two children (73.33%) had better appetites and increased the amount of eating after treatment.Conclusion The study suggests that pediasure may be safely used in the treatment of children′s anorexia and effectively improve patients′ nutrition without adverse reactions.

BACKGROUND: This study aimed to observe the effect of early goal directed therapy (EGDT) on tissue perfusion, microcirculation and tissue oxygenation in patients with septic shock. METHODS: Patients with early septic shock (<24 hours) who had been admitted to the ICU of Zhongda Hospital Affiliated to Southeast University from September 2009 through May 2011 were enrolled (research time: 12 months), and they didn't meet the criteria of EGDT. Patients who had one of the following were excluded: stroke, brain injury, other types of shock, severe heart failure, acute myocardial infarction, age below 18 years, pregnancy, end-stage disease, cardiac arrest, extensive burns, oral bleeding, difficulty in opening the mouth, and the onset of septic shock beyond 24 hours. Patients treated with the standard protocol of EGDT were included. Transcutaneous pressure of oxygen and carbon dioxide (PtcO2, PtcCO2) were monitored and hemodynamic measurements were obtained. Side-stream dark field (SDF) imaging device was applied to obtain sublingual microcirculation. Hemodynamics, tissue oxygen, and sublingual microcirculation were compared before and after EGDT. If the variable meets the normal distribution, Student's t test was applied. Otherwise, Wilcoxon's rank-sum test was used. Correlation between variables was analyzed with Pearson's product-moment correlation coefficient method. RESULTS: Twenty patients were involved, but one patient wasn't analyzed because he didn't meet the EGDT criteria. PtcO2 and PtcCO2 were monitored in 19 patients, of whom sublingual microcirculation was obtained. After EGDT, PtcO2 increased from 62.7±24.0 mmHg to 78.0±30.9 mmHg (P<0.05) and tissue oxygenation index (PtcO2/FiO2) was 110.7±60.4 mmHg before EGDT and 141.6±78.2 mmHg after EGDT (P<0.05). The difference between PtcCO2 and PCO2 decreased significantly after EGDT (P<0.05). The density of perfused small vessels (PPV) and microcirculatory flow index of small vessels (MFI) tended to increase, but there were no significant differences between them (P>0.05). PtcO2, PtcO2/FiO2, and PtcCO2 were not linearly related to central venous saturation, lactate, oxygen delivery, and oxygen consumption (P>0.05). CONCLUSION: Peripheral perfusion was improved after EGDT in patients with septic shock, and it was not exactly reflected by the index of systemic perfusion.

AIM:To evaluate the repeatability of axial length (AL) and anterior chamber depth (ACD) obtained by A scan ultrasonography, and to compare AL and ACD obtained by A scan with those obtained by IOL Master.METHODS:Two hundred and fifty-seven cataract eyes of 170 patients were included.IOL Master and A scan were performed for each eye.Five measurements of IOL Master and 3 measurements of A scan were obtained.All the tested eyes were divided into 5 groups according to AL obtained by A scan:Group A (2129mm, 21 eyes).Cronbach's Alpha coefficient and intraclass correlation coefficient (ICC) were applied to evaluate the repeatability of AL and ACD obtained by A scan.Paired t test and Pearson correlation coefficient were used to analyze the differences and correlations of AL and ACD obtained by the 2 devices, respectively.Bland-Altman plots were presented to analyze the agreements of AL and ACD obtained by the 2 devices.RESULTS:All the Cronbach's Alpha and ICCs of AL and ACD values were more than 0.98.The differences of AL values between A scan and IOL Master were-0.11±0.08mm in Group A,-0.15±0.10mm in Group B,-0.19±0.15 mm in Group C,-0.29±0.16mm in Group D and-0.45±0.29mm in Group E, respectively (all P<0.01).The differences of ACD values between A scan and IOL Master were-0.10±0.16mm in Group A,-0.06±0.13mm in Group B,-0.06±0.13mm in Group C,-0.19±0.10mm in Group D,-0.18±0.21mm in Group E, respectively (all P<0.01).In all groups, the AL and ACD values obtained by A scan and IOL Master presented good correlations (all r>0.89, all P<0.01).CONCLUSION:The AL and ACD values in cataract eyes obtained by A scan were repeatable.The AL and ACD values obtained by A scan were smaller than those obtained by IOL Master.With the increase of AL values, the differences of AL values between A scan and IOL Master increased.

Objective To analyze the safety and diagnostic value of ultrasound-guided biopsy with simple biopsy clip in children.Methods Under simple biopsy clip 52 cases were performed percutaneous renal biopsy.Then the curative rate and the incidence rate of complications were evaluated.Results Of 52 cases,49 cases(94.23%) gained enough renal tissue specimen for histological evaluation;Three failed cases occurred at early stage,nothing was found at later stage.The main complication was macroscopic hematuria occurred only once or twice after the operation and perirenal hematoma in 1.92% of the cases.No other severe complications were found.Conclusions The biopsy clip is convenient and sterile,and can guide the biopsy device exactly and safely.The use of 18-gauge biopsy gun and the automated biopsy device in children can decrease the complication rate,which can be easily performed.

Objective To explore the change of serum zinc level of children with rotavirus(RV) enteritis and efficacy of zinc supplementation on children with rotaviral enteritis.Methods One thousand one hundred and eighty-three healthy children were enrolled in this study,who were divided into different groups,and the zinc levels of children in every different age group were detected.These levels were used as normal levels of children in Dongguan district.One hundred and forty-three diarrhea patients in this 2 years were enrolled.Confirmed dia-gnosis was depended on the RV test in patients′ stool.The children with diarrhea were randomly divided into zinc treatment group (n=72) and conventional therapy group (n=71).The serum zinc levels in RV enteritis was analyzed.The patients in conventional therapy group were received diarrhea conventional therapy inchuded smectite and fluid infusion and so on;in addition to diarrhea conventional therapy,zinc gluconate 20 mg/d (10 mg/d below 6 months of age) for successive 14 days were given the patientsin zinc treatment group.The different efficacy of the 2 groups and the changes of serum zinc in treatment group were analyzed.Results Compared with normal children,the ones suffering from RV enteritis had lower serum zinc level(P0.05).Conclusions The ones suffering from RV enteritis have lower serum zinc level.In addition to diarrhea conventional therapy,giving zinc treatment has better effect on enhancing curative effect of RV enteritis.On the other hand,the suggestion of zinc supplement made by WHO is also suitable for Chinese children.

Objective To investigate the association between single nucleotide polymorphisms (SNPs)in cytokine IL-6, IL- 10 genes and HBV-related hepatocellular carcinoma(HCC). Methods A hospital-based case-control study was conducted in 381 cases with HBV-related HCC, 340 HBsAg carriers and 359 non-tumor controls. Genotypes of-572 site of IL-6 gene and-819, -592 sites of IL-10 gene were determined by real-time polymorphism chain reaction. Unconditional logistic regression was used to estimate the odds ratios(ORs)and 95 confidence intervals(C/s). Results For the G/C alleles of -572 loci on IL-6 gene, there were significant differences between the three groups(P＜0.05). Compared with CC genotype, GG genotype increased the risk of HBV infection (OR=2.171,95% Ch 1.068-4.415), but did not seem to be associated with HCC. For the alleles of-819 and -592 site of IL-10 gene, there were significant differences between the three groups(P＜0.05). Compared with CC genotype, TT genotype increased the risks of both HCC(OR=2.791,95%CI:1.326-5.874), and HCC in HBsAg carriers(0R=3.522,95%CI: 1.707-7.266). When compared with CC genotype on -592 site, the AA genotype reduced the risk of both HCC(OR=0.389, 95% CI:0.173-0.875), and HCC in HBsAg carriers(OR=0.336, 95% CI: 0.154-0.734). Conclusion The SNPs in -572 site of IL-6 gone might be associated with the risk of HBV infection. The SNPs in -819 site of IL-10 gene increased the risk of HCC, but -592 site of IL-10 gene decreased the risk of HCC.

OBJECTIVEThe present study is concerning qualitative and quantitative detection of Poria cocos quality based on FT-near infrared (FT-NIR) spectroscopy combined with chemometrics.

METHODThe Poria cocos polysaccharides contents were determined by UV. Transmission mode was used in the collection of NIR spectral samples. The pretreatment method was first derivation and vector normalization. Then principal component analysis (PCA) was used to build classification model and partial least square (PLS) to build the calibration model.

RESULTThe results showed that conventional criteria such as the R, root mean square error of calibration (RMSEC), and the root mean square error of prediction (RMSEP) are 0.944 0, 0.072 1 and 0.076 2, respectively. The misclassified sample is 0 using the qualitative model built by PCA.

CONCLUSIONThe prediction models based on NIR have a better performance with high precision, good stability and adaptability and can be used to predict the polysaccharose content of Poria cocos rapidly, which can provide a fast approach to discriminate the different parts of Poria cocos.

Taxol is one of the most potent anti-cancer agents, which is extracted from the plants of Taxus species. Isopentenyl diphosphate isomerase (IPI) catalyzes the reversible transformation between IPP and DMAPP, both of which are the general 5-carbon precursors for taxol biosynthesis. In the present study, a new gene encoding IPI was cloned from Taxus media (namely TmIPI with the GenBank Accession Number KP970677) for the first time. The full-length cDNA of TmIPI was 1 232 bps encoding a polypeptide with 233 amino acids, in which the conserved domain Nudix was found. Bioinformatic analysis indicated that the sequence of TmIPI was highly similar to those of other plant IPI proteins, and the phylogenetic analysis showed that there were two clades of plant IPI proteins, including IPIs of angiosperm plants and IPIs of gymnosperm plants. TmIPI belonged to the clade of gymnosperm plant IPIs, and this was consistent with the fact that Taxus media is a plant species of gymnosperm. Southern blotting analysis demonstrated that there was a gene family of IPI in Taxus media. Finally, functional verification was applied to identify the function of TmIPI. The results showed that biosynthesis of β-carotenoid was enhanced by overexpressing TmIPI in the engineered E. coli strain, and this suggested that TmIPI might be a key gene involved in isoprenoid/terpenoid biosynthesis.

OBJECTIVETo observe the clinical effect of acupuncture on acute heart failure (AHF) patients.

METHODSTotally 60 patients who were diagnosed as AHF were assigned to the acupuncture group and the control group, 30 in each group. Those in the control group received inotropic agents, preload and afterload reducing therapy, anti-infection and so on. Besides, those in the acupuncture group received needling at relative points, once daily for 5 consecutive days. The mean arterial pressure (MAP), heart rate (HR), cardiac index (CI), stroke volume index (SI), left ventricle working index (LCWI) were monitored by thermodilution pulse-indicated continuous cardiac output (PiCCO) technique. Changes of the aforesaid data were compared between before and after treatment. The ICU length of stay, readmission rate,and the 28-day mortality were also compared between the two groups.

RESULTSAfter 5 days of the treatment, CI, SI, and LCWI increased more obviously (P < 0.01), HR and MAP decreased significantly (P < 0.05). Of them, CI, SI, and LCWI increased more obviously in the acupuncture group (P < 0.05).There was no obvious difference in HR or MAP between the two groups (P > 0.05). Compared with the first day of admission in the same group, CI, SI, and LCWI obviously increased in the acupuncture group from the second day (P < 0.05). HR started to decrease since the fourth day (P < 0.05), and MAP began to decrease until the fifth day (P < 0.05). CI, SI, and LCWI started to increase in the control group from the third day (P < 0.05); HR and MAP both began to decrease since the fifth day (P < 0.05). Compared with the control group, the ICU length of stay was obviously shortened in the acupuncture group (P < 0.05). The readmission rate and the 28-day mortality rate were lower than those of the control group (P < 0.05).

CONCLUSIONThe combination of acupuncture and Western medical therapy might strengthen acute heart failure patients' heart functions, elevate the therapeutic effect, and improve the prognosis.
