objective To observe the distribution of vitamin D receptor(VDR)gene polymorphisms in children of Han nationality and investigate the relationship between VDR gene polymorphisms and the susceptibility to children's dental fluorosis of Han nationality.Methods From October of 2008 to March of 2009,a case-control study was conducted among children between 8 and 12 years old with(n=101)and without(n=102)dental fluorosis using Dean method in Guandian countyside of Fengtai county in Anhui province.DNA was extracted from blood samples ofthese children.The Apa I,Bsm I,Fok I and raq I polymorphisms in the VDR gene were genotyped using polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP).The distribution of the genotypes in patients and the control group were analyzed. Results Different genotypes of the VDR gene existed in children of Han nationality with the highest distribution frequency of Aa, bb, Ff, TT, which respectively was 51.7% ( 105/203 ), 89.7% (182/203), 52.7% (107/203), 93.1% (189/203), followed by genotype distribution frequency of aa, Bb, FF, Tt, being 39.9% (81/203),7.9% (16/203),31.5% (64/203) ,6.9% (14/203), respectively. AA,BB, ff, tt distribution frequency was the lowest as follows, 8.4% ( 17/203 ), 2.4% (5/203), 15.8% (32/203),0 (0/203). The frequency distribution of VDR Apa I genotype was AA 7.9% (8/101), Aa 55.4% (56/101), aa 36.7%(37/101) in children with fluorosis, and AA 8.8% (9/102), Aa 48.0% (49/102), aa 43.3% (44/102) in children without fluorosis, respectively. There were no significant differences in the two groups(χ2= 1.13, P > 0.05).The frequency distribution of VDR Bsm I genotype was BB 3.0%(3/101), Bb 5.9%(6/101 ), bb 91.1% (92/101) in children with fluorosis, and BB 2.0% (2/102), Bb 9.8% (10/102), bb 88.2% (90/102) in children without fluorosis, respectively. There were no significant differences in the two groups(χ2 = 0.55, P > 0.05). The frequency distribution of VDR Fok I genotype was FF 28.7%(29/101), Ff 56.4% (57/101), ff 14.9%(15/101) in children with fluorosis, and FF 34.3% (35/102), Ff 49.0% (50/102), ff 16.7% (17/102) in children without fluorosis,respectively. There were no significant differences in the two groups(χ2 = 1.14, P > 0.05). The frequency distribution of VDR Taq I genotype was TT 93.1%(94/101), Tt 6.9%(7/101) in children with fluorosis, and TT 93.1% (95/102), Tt 6.9%(7/102) in children without fluorosis, respectively. The tt genotype was not found. There were no significant differences in the two groups (χ2 = 0.00, P > 0.05 ). Conclusions Different genotypes of the VDR gene existed in children of Han nationality. There were no correlation between VDR Apa I , Bsm I , Fok I , Taq I gene polymorphisms and children's dental fluorosis of Han nationality in this area.

OBJECTIVETo investigate the risk factors for recurrent wheezing in infants and young children suffering from dust mite allergy after their first wheezing.

METHODSA total of 1 236 infants and young children who experienced a first wheezing episode and were hospitalized between August 2014 and February 2015 were enrolled, among whom 387 were allergic to dust mites. These infants and young children were followed up to 1 year after discharge. A total of 67 infants and young children who experienced 3 or more recurrent wheezing episodes within 1 year were enrolled as the recurrent wheezing group, while 84 infants and young children who did not experience recurrent wheezing during follow-up were enrolled as the control group. Univariate analysis and multivariate logistic stepwise regression analysis were performed to investigate the risk factors for recurrent wheezing in these patients.

RESULTSThe univariate analysis showed that the age on admission, wheezing time before admission, Mycoplasma pneumoniae infection rate, and influenza virus infection rate were associated with recurrent wheezing. The multivariate logistic stepwise regression analysis showed that the older age on admission (OR=2.21, P=0.04) and Mycoplasma pneumoniae infection (OR=3.54, P=0.001) were independent risk factors for recurrent wheezing.

CONCLUSIONSInfants and young children who are allergic to dust mites, especially young children, have a significantly increased risk of recurrent wheezing if they are complicated by Mycoplasma pneumoniae infection during the first wheezing episode.

This study was purposed to analyze the methylation status of death-associated protein kinase (dapk) gene promoter in Chinese patients with acute myeloid leukemia (AML) and its relationship with clinical features. The methylation-specific PCR (MSP) technique was used to detect dapk promoter methylation in bone marrow samples from 112 cases of AML. The results indicated that gene dapk promoter hypermethylation was detected in 82 cases (73.2%), but not in 13 control group. There was no correlation of dapk gene hypermethylation with sex, age, WBC counts, platelet counts, hematologic parameters, chromosomal abnormalities and different subtypes of AML patients. It is concluded that dapk gene hypermethylation may be a common molecular event in AML.

OBJECTIVETo evaluate the prognostic significance of metastatic lymph nodes ratio in patients with T(2)~T(3) stage gastric cancer.

METHODSClinical data of 238 patients with T(2)-T(3) stage gastric cancer undergone radical gastrectomy and D(2) lymphadenectomy, at least 15 lymph nodes was dissected per patient, were analyzed retrospectively. Spearman correlation analysis was used to determine the correlation coefficient. Survival was determined by the Kaplan-Meier method and differences were assessed by the Log-rank test. Multivariate analysis was performed using the Cox proportional hazard regression model in forward stepwise regression. Receiver working characteristic curve was used to compare the accuracy of the metastatic lymph nodes ratio in predicting the death of patients 5 years postoperatively and that of metastatic lymph nodes number.

RESULTSThe metastatic lymph nodes ratio didn't correlate with the total number of dissected lymph nodes, whereas metastatic lymph nodes number did. Kaplan-Meier survival analysis demonstrated the metastatic lymph nodes ratio significantly influenced the postoperative survival time and Cox proportional hazard regression model analysis showed the metastatic lymph nodes ratio was an independent poor prognostic factor. There was no significant difference between the area under the receiver working characteristic curve of metastatic lymph nodes ratio and metastatic lymph nodes number in predicting the death of patients 5 years postoperatively.

CONCLUSIONSThe metastatic lymph nodes ratio in T(2)-T(3) stage gastric cancer patients is not correlated with the total number of dissected lymph nodes if at least 15 lymph nodes are dissected. The metastatic lymph nodes ratio is a major independent poor prognostic factor of the patients of T(2)-T(3) stage gastric cancer. The ability of the metastatic lymph nodes ratio in predicting the death of T(2)-T(3) stage gastric cancer patients 5 years postoperatively is the same as that of metastatic lymph nodes number.

Objective To investigate the relationship between children's body mass index (BMI)at 5 to 6 years old and glucose concentrations of mothers without pre-existing diabetes or a gestational diabetes mellitus(GDM) diagnosis during pregnancy.Methods A prospective observational study was performed in offspring whose mother had no pre-existing diabetes or a GDM diagnosis during pregnancy in the First Affiliated Hospital of Kunming Medical Uni versity from Jan.2006 to Dec.2007.The data of maternal glucose concentrations of oral glucose tolerance test(OGTT)were acquired through referring to clinical records.Weight and height at 5 to 6 years old were measured and used to calculate BMI.Multivariable linear regression models were used to examine the association between children's BMI and maternal glucose concentrations.The influence of maternal glucose concentrations on the risk of overweight of offspring was analyzed by Logistic regression.Results There were 860 cases of children were followed-up,including 459 male cases and 401 female cases.The average BMI of children was(15.6 ± 2.7) kg/m2.There were 78 cases of overweight (9.06％) and 50 cases of obesity(5.81％).The mean maternal fasting glucose level of the OGTT was (3.8 ± 0.6) mmol/L and 2 h glucose level of the OGTT was (6.0 ± 0.9) mmol/L.After adjusting for progestation BMI,maternal weight gain during pregnancy,sex,birth weight,age and paternal weight,at the 5 to 6 years old,BMI of offspring of mothers whose fasting glucose level of the OGTT≥5.51 mmol/L were significantly higher than those of mothers whose average blood glucose level ＜5.51 mmol/L(β =0.45,95％ CI:0.15-0.80).Maternal fasting glucose level of the OGTT≥5.51 mmoL/L was associated with an greater risk of children's overweight(OR =2.32,95％ CI:1.30-3.96).Conclusions Even though the mother was in the absence of pre-existing diabetes or GDM during pregnancy,fetal exposure to high maternal glucose concentration may also promote the development of overweight in the offspring at 5 to 6 years old.

OBJECTIVEThe aim of this study was to assess the long-term clinical outcome of patients with diabetes mellitus and chronic total occlusion (CTO) underwent drug-eluting stents (DES) implantation.

METHODSData of 143 consecutive eligible patients from January, 2006 to May, 2007 were retrospectively analyzed. The endpoint of the study was the major adverse cardiac events (MACE), including death, myocardial infarction, target lesion revascularization. The patients were divided into two groups, event group and non-event group, according to the result of follow-up.

RESULTSLong-term follow-up was finished in 139 (97.2%) patients. Mean follow-up duration was (19.8 + or - 5.1) months. MACE rate was 10.5% during follow-up: 3 deaths, 1 myocardial infarction and 11 repeated target lesion revascularization with PCI. Compared with the non-event group, the percentage of residual lesion [(17.7 + or - 1.8)% vs. (15.4 + or - 5.0)%, P = 0.001] was significantly higher in the event group, however, the final minimal luminal diameter [(2.14 + or - 0.22)% vs. (2.89 + or - 0.37)%, P = 0.004] was lower. Cox regression analysis showed that final luminal diameter (OR: 0.097, 95%CI: 0.013 - 0.694, P = 0.020) was the only dependent predictor at follow-up.

CONCLUSIONFinal minimal luminal diameter is an independent predictor of MACE during follow-up for patients with diabetes and CTO underwent DES implantation.

Objective: To compare the 6-month follow-up results of primary percutaneous coronary intervention (PPCI) guided by optical coherence tomography (OCT) or coronary angiography (CAG) alone in a larger ST-segment elevation myocardial infarction (STEMI) cohort. Methods: We enrolled 275 STEMI patients undergoing OCT-guided PPCI from March 2017 through December 2018. Two hundred and seventy-five propensity score matched STEMI patients undergoing CAG-guided PPCI served as control group. The 6-month clinical follow-up results were compared between the two groups. The demographic data, complications, coronary angiography and OCT characteristics were evaluated. Results: OCT evaluation showed that there were 151 patients (54.9%) with plaque prolapse and 113 patients (41.1%) with stent malposition. Proximal and/or distal dissection of stents occurred in 38 patients (13.8%), of which 3 patients (1.1%) had both proximal and distal dissection. Of the 38 patients, 2 patients received rescue stent implantation. Results of clinical follow-up at 6 months showed that there was no significant difference in cardiovascular death, repeat myocardial infarction, target vessel revascularization, stroke and hemorrhage endpoint events between OCT-guided PPCI patients and CAG-guided PPCI patients (P=0.682). Conclusion: Clinical events at 6 months are similar between OCT-guided PPCI and CAG-guided PPCI for STEMI patients.

OBJECTIVETo investigate the efficacy, safety and the life quality improvement of uroacitides injection in the treatment for patients with advanced malignant tumors.

METHODSA total of 160 patients with advanced stage cancers were enrolled into this multicenter, open and non-randomized phase II clinical trial, including cancers of the lung (33 cases), liver (45 cases), breast (17 cases), esophagus (11 cases), stomach (18 cases), colon (19 cases), pancreas (3 cases) and kidney (4 cases), and glioma (10 cases). Uroacitides was administrated in a dose of 300 ml daily via the superior vena cava catheter for consecutive 4-8 weeks.

RESULTSOf the 160 patients, 21 dropped out and one patient died during the trial. Efficacy could be evaluated in 138 patients and safety in 160. The total objective response rate (ORR, CR + PR)) and tumor control rate (CR + PR + MR + SD) of the 138 evaluable patients were 5.8% and 65.2%, respectively. Clinical benefit response (CBR) rate was 57.2%. Major adverse effects were grade I - II and reversible nausea/vomiting (21.9%) and pain (6.3%).

CONCLUSIONUroacitides injection is effective in the control for various kinds of advanced cancers with mild, reversible and tolerable adverse effects, and can also improve the patient's quality of life. It is worth being studied further.
