ABSTRACT

Objective@#To investigate vitamin D levels among primary and middle school students in Xicheng District, Beijing Municipality, and to examine the association of vitamin D levels with hemoglobin (Hb) and serum ferritin (SF) levels, so as to provide insights into the prevention of anemia among primary and middle school students. @*Methods@#The first, third and fifth grade primary school students and the first grade junior high school students were sampled from Xicheng District in 2019, using the multistage stratified cluster sampling method, and students' gender, age, height, weight and Hb levels were collected. The 25-hydroxyvitamin D [25-( OH )D] was measured using electrochemiluminescence assay, and SF was detected using immunoturbidimetry. The vitamin D deficiency was determined according to the American College of Endocrinology guidelines. The associations of 25-( OH) D levels with Hb and SF levels were examined using Pearson correlation analysis and Spearman rank correlation analysis. @*Results@#Totally 403 primary and junior high school students were investigated, including 196 boys ( 48.64% ) and 207 girls ( 51.36% ). There were 179, 114 and 110 students at ages of 6 to 8 years ( 44.41% ), 9 to 11 years ( 28.29% ) and 12 to 13 years ( 27.30% ), respectively. The mean 25-( OH )D level was ( 14.80±5.96 ) ng/mL among the study students, and there were 90 students ( 22.33% ) with severe vitamin D deficiency, 243 students ( 60.30% ) with vitamin D deficiency, 63 students ( 15.63% ) with vitamin D inadequacy and 7 students ( 1.74% ) with vitamin D sufficiency. The mean Hb level was ( 136.28±8.33 ) g/L and the median SF level (interquartile range) was 56.80 (14.36) ng/mL among the study students, respectively. The 25-( OH )D level positively correlated with Hb ( r=0.364, P<0.001 ) and SF levels ( rs=0.374, P<0.001 ), and after adjustment for age and body mass index, the 25-( OH )D still correlated positively with Hb ( r=0.157, P=0.048 ) and SF levels ( rs=0.174, P=0.022 ) .@*Conclusions@#Vitamin D deficiency is prevalent among primary and middle school students in Xicheng District, and the 25-(OH)-D levels correlate positively with Hb and SF levels. 25-( OH )-D deficiency may contribute to the development of anemia.

ABSTRACT

Objective To compare short-term therapeutic outcomes and the safety of percutane-ous radiofrequency ablation (PRFA) with left single lung ventilation (LSLV) for liver cancer of the hepatic dome (LCHD) and that of PRFA for right liver carcinoma in favorable location. Methods Thirty one patients with hepatocellular carcinoma (belonging to LCHD) receiving PRFA with LSLV (Group LCHD) between January 2006 and January 2009 in our hospital were selected, and 45 control patients with right lobe HCC ≥1 cm away from the liver capsule, gallbladder, and main portal bran-ches were also included. One month after PRFA, residual tumors were followed up with contrast en-hanced CT and alpha fetal protein and PRFA was repeated in the presence of residual foci. Tumor-free survival time was defined as the duration from complete ablation to diagnosed local tumor progression.The Mann-Whitney test was used to compare age, tumor diameter, and average number of punctures between LCHD patients and controls. A χ2 test was used for comparison of the incidence of complica-tions and incomplete tumor ablation rate. The Kaplan-Meier's method was used for calculation of local tumor-free survival rate compared with a log-rank test. Results The incidence of right shoulder pain was significantly higher in LCHD patients than in controls (87. 1% vs 11. 1%, P<0. 01). LCHD pa-tients showed no difference from controls in the average number of punctures (2. 8±. 5 vs 3. 2±. 5,P>0. 05). Meanwhile, there was no difference between the 2 groups in average duration of treatment and hospitalization, and the complete tumor ablation rate at first PRFA. No differences were observed in the 1-, 2- and 3-year local tumor-free survival rates between LCHD patients (85. 5% , 65. 8% , and 36. 4% ,respectively) and controls (87.7%, 62. 3% , and 34.0% , respectively). Conclusion PRFA with LSLV for LCHD seems to promise comparable short-term outcomes and safety to PRFA for right liver carcinoma of fa-vorable location and should be preferred as one of the therapeutic options for LCHD patients with tumor di-ameters≤5 cm regardless of its unique location.

ABSTRACT

Objective To assess the therapeutic efficacy and safety of CT-guided percutaneous radiofrequency ablation(PRFA) for hepatocellular carcinoma in the bare area (HCCBA). Methods During the period from April 2000 to June 2009, 26 patients with HCCBA were treated with CTguided PRFA, and 26 other HCC patients were selected as controls, whose lesions were located in the right lobe ≥1.0 cm away from the liver capsule, gallbladder, and main portal branches. One month after PRFA, the residual tumors of each patient were examined by contrast-enhanced CT and alpha-fetoprotein test, and repeated PRFA was undertaken if residual was present. Tumor-free survival was defined as the duration from complete ablation to diagnosed local recurrence. The 2-independent-samples t-test was used to compare tumor diameter between HCCBA patients and controls. The MannWhitney U test was used to compare patient's age, etiologies of liver disease, liver function status,number of needle punctures and the value of AFP. A χ2 test was used for comparison of the complete tumor ablation rate and the cumulative local tumor-free survival rate. Results No significant difference was observed in the incidence of complication between the HCCBA patients and the controls (26. 9% vs 19.2%,P>0.05). There were no differences between the two groups in the number of needle punctures and the complete tumor ablation rate at first PRFA. Furthermore, no differences were observed in the cumulative 1-,3- and 5-year local tumor-free survival rates between HCCBA patients (88. 5%, 46.2% and 19. 2% respectively) and patients in the control group (92.3%, 53.8% and 15.4% respectively). Conclusion CT-guided PRFA is effective and safe for HCCBA and could be preferred as one therapeutic option for HCCBA.

ABSTRACT

Objective: To investigate effect of exogenous wild-type p53 gene on the cell growth and tumorigenicity of human gallbladder cancer cell lines. Methods: After identification of the genetic status of p53 gene of GBC-SD cell lines with the immunocytochemistry staining and the direct sequencing technique of PCR products, eukaryotic expressing plasmid pCMV-p53 was introduced by lipofectamine-mediated into GBC-SD cell lines. Growing transfected cells were selected by G418. The presence and expression of exogenous p53 gene was detected by PCR, RT-PCR and Western blot. The cellular proliferating ability was assessed using the cell growth curve and cloning assay. The xenograft in nude mice was performed to examine the effect of tumorigenicity. Results: P53 protein overexpression was showed in GBC-SD cell lines. A transversion of TAC→AAC at codon 126 of exon 5 was confirmed. PCR, RT-PCR and Western blot showed exogenous p53 gene had successfully transfected into GBC-SD cells and obtained high expression. The growth and proliferation of the cells were greatly decreased, and the tumorigenicity was significantly inhibited after transfection wtp53. Conclusion: The expression of exogenous wild-type p53 gene could effectively inhibit the growth of gallbladder cancer GBC-SD cells in vitro and in vivo.
