ABSTRACT
Objective@#To determine the association between the intake of five major types of prepackaged foods and the growth and development of school aged children, so as to provide a theoretical basis for guiding school aged children and their parents to make healthy prepackaged food choices.@*Methods@#Based on data from the South West China Childhood Nutrition and Growth Cohort (SCCNG), 381 children (6-11 years of age) were selected by stratified cluster sampling. Dietary intake and pubertal development were collected using questionnaires, and anthropometric measurements were obtained. Children were followed up until November 2022. Binary Logistic regression models were used to analyze the prospective association between prepackaged food intake and the growth and development of school aged children.@*Results@#The total intake of the five major types of prepackaged foods was 316.1 (197.1,501.4) g/d. After 2 years of follow up evaluations, 16.5% of school aged children were shown to be overweight and obese. Early spermarche occurred in 12.6% of boys and early menarche occurred in 15.4% of girls. The following findings were suggested after adjusting for the mothers education level, average gross monthly family income, whether or not the family had one child only, geographic area of residence, body mass index Z score, average duration of daily exercise, and total dietary energy intake: convenience food intake might increase the risk of early spermarche ( OR =9.37); fruit and vegetable intake might decrease the risk of early spermarche and menarche ( OR =0.33,0.17); and fish, poultry, meat, and egg intake might increase the risk of early menarche ( OR =7.59)( P <0.05). Intake of the five types of prepackaged foods was not associated with being overweight or obese after adjusting for confounders ( OR =1.40, 0.57, 0.73, 1.33,1.57, P >0.05).@*Conclusions@#The relationship between intake of the five major types of prepackaged foods and pubertal development is inconsistent and no significant correlation was detected between the intake of prepackaged foods and overweight or obese children. Nutrition education should be strengthened to help children and their parents choose healthy prepackaged foods.
ABSTRACT
Objective: Due to the complicated compounds and the synergistic effect of multi-compounds, the quality control and assessment of Chinese materia medica (CMM) encounters a great challenge about how to identify the key compounds, which are directly correlated with its efficacy and safety. On the guidance of study on quality marker (Q-Marker), identification of Q-Markers was performed from Hedan Tablet (HDT) by the aid of the “spider-web” mode and hepatotoxicity evaluation derived from our previous researches and literatures. Methods: By the established ultra performance liquid chromatography with photodiode array detector (UPLC-PDA) method, online UPLC-DPPH· and offline antioxidant assay, 21 candidate compounds of HDT were systematically investigated and comprehensively evaluated by the “spider-web” mode for them properties of Q-Marker based on “content-stability-activity”. In addition, the Q-Markers related with hepatotoxicity based on our previous researches and literatures were identified. Results: Salvianolic acid B (SaB), quercetin-3-O-glucuronide (Qug), isoquercitrin (IQ) and hyperoside (Hyp) were adopted as the preferable Q-Markers of HDT according to the shaded area (A) of tested compounds in “spider-web” mode. Psoralen (Ps), isopsoralen (IP), psoralenoside (PO) and isopsoralenoside (IPO) were also strongly recommended as Q-Markers closely related with safety by considering hepatotoxicity of the accumulated Ps and IP and conversion between glycoside (PO and IPO) and aglycone (Ps and IP). Conclusion: This study provided scientific evidence for quality control and assessment of HDT, and also provided a meaningful reference for application of Q-Markers in CMM.

Objective:To investigate the association between metabolic factors,such as obesity,blood pressure,blood glucose,serum lipid profile,and the histopathological characteristics of renal cell carci-noma.Methods:The medical records of 382 consecutive renal cell carcinoma patients who underwent radical or partial nephrectomy at Peking University People’s Hospital from January 2009 to January 2015 were retrospectively reviewed.Metabolic factors were collected from the records,including weight,body mass index,waist circumstance,blood pressure,fasting blood glucose,serum total triglyceride,serum total cholesterol,serum low-density lipoprotein-cholesterol and serum high-density lipoprotein-cholesterol. The patients were divided into different groups according to tumor grade,stage and diameter.Statistics analysis,such as t test,Mann-Whitney U test and Logistic analysis,were performed to investigate the as-sociation between metabolic factors and grade,stage and tumor diameter of renal cell carcinoma.Re-sults:A total of 80 (20.94%)of the tumors were classified as high grade disease,63 (16.49%)were classified as advanced disease and 153 (40.05%)tumor diameter more than 4 cm.The patients in high grade group were found to have lower high-density lipoprotein-cholesterol level than in low grade group (P =0.015),body mass index,total cholesterol and high-density lipoprotein-cholesterol were found to be lower in advanced disease than in localized disease (P =0.022,P =0.005 and P =0.006,respec-tively),and low-density lipoprotein-cholesterol was found to be lower in larger tumors (P =0.030). Other factors were comparable between the different groups.The results of Logistic analyses showed that, body mass index (OR =0.906,95%CI:0.852 -0.986,P =0.023)and total cholesterol (OR =0.660,95%CI:0.492 -0.884,P =0.005)were associated with the tumor stage,high-density lipopro-tein-cholesterol level was significantly associated with tumor grade (OR =0.293,95% CI:0.108 -0.797,P =0.016)and stage (OR =0.204,95%CI:0.065 -0.635,P =0.006),and low-density lipoprotein-cholesterol level was significantly associated with tumor diameter (OR =0.756,95% CI:0.586 -0.975,P =0.031).Conclusion:The results of our study indicate that metabolic factors,espe-cially obesity and serum lipid profile,are closely related with the histopathological characteristics of renal cell carcinoma.
ABSTRACT
Objective:To investigate the expression of MEK/ERK signaling pathways in renal cell car-cinoma with bone metastasis,and to analyze the differences of expressions of VEGFR-2,MEK,ERK on the primary and metastasis tissue and its mechanism.Methods:The tissue samples were obtained from 7 renal cell carcinoma patients kindly provided by Department of Urology,Peking University People’s Hos-pital from January 1,2009 to January 1,2010.The expression of MEK/ERK signaling pathways was de-tected in the 7 renal cell carcinoma patients`primary and matched metastatic tissues with ICH,The anti-body concentrations were 1 ∶200,1 ∶25,and 1 ∶250,respectively.The mutation of the twentieth exon of the PDGFRA gene,the second exon of the K-ras gene,the fifteenth exon of the Brafgene and the se-cond exon of the MEK1 gene were detected with PCR.Results:The expression intensities of VEGFR-2, MEK,and ERK were measured by H-score [intensity (1,2,3,or 4)multiplied by the distribution (%)].VEGFR-2,MEK,and ERK expressions were divided into 3 groups according to the positive dis-tribution of the tumor cells:1,0 -5%;2,6% -50%;and 3,>50%,To assess intratumor heteroge-neity,three distinct microscopic fields (×200)from each specimen were used to evaluate the expres-sions,Subsequently,the scores were averaged to obtain a single concatenated score for each tissue. VEGFR-2,MEK,and ERK expressions were assessed by 2 independent pathologists who were blinded to the clinicopathological data.The data were expressed as the mean value of the triplicate experiments.The expressions of MEK,and ERK were higher in the metastatic tissues than in the matched RCC tissues (6.10 ±4.10 vs.1.33 ±0.51,P =0.015;9.10 ±2.24 vs.4.43 ±2.84,P =0.021 )while the ex-pression of VEGFR-2 was not different between the primary and metastatic tissues (P =0.901).No mu-tation was detected on the twentieth exon of the PDGFRA gene,the second exon of the K-ras gene,the fifteenth exon of the Brafgene and the second exon of the MEK1 gene.Conclusion:MEK/ERK signa-ling pathways may play an important role in the metastasis and the resistance of sunitinib in RCC patients with bone metastasis.

Objective To culture the acute leukemia cells in vitro,and to prepare cancer vaccine expressing heat shock protein 70 (HSP70) of Bacille Calemette-Geérin(BCG) onto the cell surface,so as to study its anti-tumor effect and mechanism.Methods Acute myeloid leukemia (AML) cells were cultured in a serum-free Stemspan(H) culture supplemented with cytokines [stem cell factor(SCF),flt-3 ligand (FL),interleukin (IL)-3 and IL-6] in vitro.And B-lineage acute lymphoblastic leukemia (B-ALL) cells were cultured in a Iscove modified medium(IMDM) culture supplemented with cytokines (SCF,FL,IL-3 and IL-7) in vitro.Cellular morphology was observed by the microscopy and immunophenotype determination was used to verify the biological characteristics of acute leukemia cells after culture.Lipofectamine 2000 was used to transfect the pDisplay-HSP70 plasmid into acute leukemia cells.The expression of HSP70 on the cell surface was detected by fluorescene microscope.Then the immunogenicity of the leukemia cells expressing HSP70 were detected.The experimental groups were divided into 3 subgroups:the wide-type acute leukemia cells (wt-LC group),the pDisplay-leukemia cells (pDisplay-LC group),and the pDisplay-HSP70-leukemia cells (HSP70-LC group),respectively.The leukemia cells in different groups were cultured with autologous peripheral blood T cells for 72 hours.The proliferation indices of T cells were assayed by carboxyfluorescein diacetate succinimidyl ester (CFSE)-staining method,and the contents of interferon-γ(IFN-γ) were tested by enzyme-linked immunosorbent assay (ELISA).The leukemia cells in different groups were cultured with autologous peripheral blood T cells,and after 6 days,the fresh acute leukemia cells were added [in the different ratios of cytotoxicity T lymphocyte (CTL):leukemia cells were 10 ∶ 1,20 ∶ 1,40 ∶ 1 and 80 ∶ 1] and continued to be cultured for another 12 hours.Cytotoxicity assay was measured by lactate dehydrogenase (LDH) release.Results After short term culture in vitro,the leukemia cells were in colony-like suspension and maintain the proliferation characteristics were maintained.The cell proliferation was rapidly cultured for about 10 days and then was gradually slowed down.But there was no difference between the day 10 and day 0 in the expressions of CD13 and CD33 in fifteen cases of AML cells (P ＞ 0.05).Equally,there was no difference between the day 10 and day 0 in the expressions of CD19,CD10 and CD22 in fifteen cases of B-ALL cells (P ＞ 0.05).After BCG HSP70 gene transfection,the yellow-green fluorescence on the leukemia cells surface was observed under the confocal microscope.Detection of the immunogenicity:(1) Autologous T cell proliferation:the most significant T cell proliferation was observed in the group of HSP70-transfected leukemia cells (t =17.89,19.58,all P ＜0.05).There was no difference between the wt-LC group and pDisplay-LC group (P ＞ 0.05).(2) The contents of cytokines:the IFN-γ level in the group of HSP70-transfected leukemia cells was higher than those of wide-type acute leukemia cells and the pDisplay-transfected ones (t =24.72,24.81,all P ＜ 0.05).(3) Cytotoicity of CTL:the killing rate in HSP70-transfected leukemia cells was significantly higher than those of wide-type acute leukemia cells and pDisplay——transfected ones(F =13.66,P ＜ 0.05).And with the increase of the ratio from 10 ∶ 1 to 80 ∶ 1,the inhibiting activity of CTL in the HSP70-LC group was raising(F =19.69,P ＜ 0.05).Conclusions Fresh acute leukemia cells can be successfully cultured in vitro.Short-term culture can significantly increase the number of leukemia cells,but has little effect on surface antigen expression.So,the biological characteristics of the leukemia cells can be maintained.The leukemia cells vaccine expressing BCG HSP70 onto its surface was successfully prepared,and gene transfection of BCG HSP70 can significantly enhance the immunogenicity of leukemia cells.
ABSTRACT
Objectives To prepare the HL-60 cell vaccine expressing heat shock protein 70 (HSP70) of Bacille calmette-Guérin (BCG), so as to study its anti-tumor effect and mechanism. Methods The whole BCG HSP70 gene was amplified from BCG genome by polymerase chain reaction (PCR) and sub-cloned into the polyclone endonuclease sites in pDisplay. The recom-binant vector of pDisplay-HSP70 was verified by sequencing. Then the HL-60 cell vaccine expressing the protein onto the cell surface was prepared by lipofectamine transfection. To detect the immunogenicity of HL-60 cells expressing HSP70, the test groups were divided into three subgroups, HL60-wt, HL60-pDisplay, and HL60-HSP70 respectively. Each group was cultured with peripheral blood T cells for 72 h, then the proliferation indices of T cells were assayed by CFSE-staining method, and IFN-γwere tested by enzyme-linked immunosorbent assay (ELISA). The HL-60 cells of different groups were cultured with peripher-al blood T cells for 6d. The wild-type HL-60 cells were added and co-cultured for another 12h. Cytotoxicity assay was measured by LDH release. Results (1) The fragment of BCG HSP70 was consistent with the theoretical value. DNA sequencing showed that the recombinant vector of pDisplay-HSP70 was correctly constructed. (2) BCG HSP70 expressed onto the HL-60 cells sur-face. (3) Detection of the immunogenicity: ①The most significant T cell proliferation was observed in the group of HSP70-transfected HL-60 cells (P0.05).②The contents of IFN-γof the HSP70-HL60 group was the highest.③The inhibiting activity of CTLs on HL-60 cells in the group of HSP70-transfected HL-60 cells was more significant than that of wide-type and pDisplay--transfected HL-60 cells. And with the increase of the E:T ratio, the inhibiting activity of CTLs in the HSP70-HL60 group was rising. Conclusions The recombinant eukaryotic expression vector (pDisplay-HSP70) of BCG HSP70 was successfully constructed. And the HL-60 cell vaccine expressing BCG HSP70 onto its surface was successfully prepared. The results showed that gene transfection of BCG HSP70 could significantly enhance the immunogenicity of HL-60 cells.
ABSTRACT
Objective To compare the clinical outcomes of using the Hukou artery and ulnar proper digital artery of index finger translocation to reconstruct artery supply in replanting of rotated and avulsed thumb.Methods From January 2011 to May 2012,replantation surgery were carried out in 16 patients with rotated and avulsed injury of thumb.In group A,all cases were replanted by Hukou artery translocation,in which 6 males and 2 females and (27.0 ±9.5) years old in average.The causes of injury were machine strangulation (7 patients) and traffic accident (1 patient).The average time from injury to operation were(6.1 ± 3.1) hours.The amputed level were at the base of proximal phalanx (5 patients) and metacarpophalangeal joint (3 patients).In group B,all patients were replanted using ulnar proper digital artery of index finger translocation,in which 5 males and 3females and (29.7 ± 13.7) years old in average.The causes of injury were machine strangulation (6 patients) and cord wring injury (2 patient).The average time from injury to operation were(7.1 ±2.2) hours.The amputed level were at the base of proximal phalanx (4 patients) and metacarpophalangeal joint (4 patients).Results The operation time were (3.2 ± 0.8) minutes in group A and (5.3 ± 0.6) minutes in group B.All fingers were survived in both groups.All patients were followed up 3-10 months (6.9 months on average).Excellent rate reached 75.0％ in group A and 75.0％ in group B according to Criterion on Functional evaluation on Finger Reconstruction issued by Chinese society of hand surgery.There were significant differences between the two groups in operation time (P ＜ 0.05),and without differences in excellent rate (P ＞ 0.05).Conclusion There are same outcome by using the Hukou artery and ulnar proper digital artery of index finger to reconstruct artery supply in replantation of rotated and avulsed thumb.However,using the Hukou artery translocation were more simple and minimally invasive.
