Objective To investigate the relationship between the expression of DNA methyltransferases(DNMT)and clinical prognosis in children with acute leukemia(AL).Methods The mRNA expressions of DNMT1,DNMT3A,DNMT3B,p15,mdrl were measured in 56 AL children and 20 normal controls by semi-quantitative reverse transcriptionpolymerse chain reaction.Results In 56 cases of children with AL,the positive rate of DNMT1 was 73.2%(41/56);the positive rate of DNMT3A was 67.9%(38 /56);the positive rate of DNMT3B was 64.3%(36/56).Thirty-one cases showed positive expressions of the 3 DNMT simultaneously,4 cases with negative expressionss imultaneously,21 cases with at least 1 positive expression of the DNMT,positive rate of p15 was 19.6%(11/56);positive rate of mdrl was 28.6%(16/56),all 3 simultaneous expressions of the 3 DNMT in AL children were significantly higher than those in normal controls(P

Objective To observe the effect of Oxycontin combined with Gabapentin for treatment of malignant neuropathic pain.Methods Sixty-three cases of malignant neuropathic pain in Jinshan Hospital Affiliated to Fudan University were randomly divided into group A, B and C.Patients of which were given Oxycontin, Gabapentin, Oxycontin combined with Gabapentin respectively for pain treatment.The analgesic effects, toxic reaction side effects, quality of life, and immune function were all compared in three groups.Results Compared with pretherapy, the cancer pain score (NRS), quality of life (QOL) and karnofsky performance status(KPS) scores in all groups were changed significantly after drugs therapy(F=375.852,154.612, 151.838,P＜0.05).The levels of CD3,CD4, CD4/CD8 and NK cells in all groups were higher than before therapy(F=158.935,108.145,366.973,92.090,P＜0.05).After treatment,the NRS, QOL and KPS scores in group C were 2.00± 0.86,44.80± 6.07, 84.50± 6.05, in group A were 3.35 ± 0.67,37.35 ± 5.71,74.50 ±10.99,and in group B were 4.05±0.94,35.85±5.90,72.00±8.34, and the different were significant (F =3.250,10.499,3.465,P＜0.05).The levels of CD3, CD4, CD4/CD8and NK cells in group C were (72.94 ±5.63)％,(41.52±4.19)％, 1.86±0.30, (27.57±6.86)％,in group A were (62.84±5.27)％, (33.84 ±5.40)％,1.35±0.37, (20.49±6.67) ％,and in group B were (62.22±8.10)％, (33.19±6.90)％, 1.32 ± ±0.41, (20.32±5.63) ％, and the different were significant (F =3.377,3.344,3.352,3.386, P＜ 0.05).The patient in group C had less adverse effects than those in group A and B.Conclusion Oxycontin and Gabapentin in treatment of malignant neuropathic pain is effective.

Objective To evaluate the value of ultrasonic elastography for diagnosis of chronic nonspecific low back pain. Methods From March to September, 2016, 32 patients diagnosed as chronic nonspecific low back pain and other 32 healthy people (controls) were measured lumbar erector spinae with ultrasonic elastography, and calculated Yang's modulus. The correlation between Yang's modulus and Visual Analogue Scale (VAS) or Japanese Orthopaedic Association (JOA) score in the patients were investigated with Pearson's analysis. Re-sults There was no significant difference in Yang's modulus between bilateral lumbar erector spinae in both the patients and the controls (t<1.849, P>0.05), but it was more in the patients than in the controls (t=9.931, P<0.001). The Yang's modulus was positively correlated with VAS score in the patients (r=0.614, P<0.001), but not with the JOA score (r=-0.243, P=0.180). Conclusion Ultrasonic elastography can be applied to differentiate low back pain from the healthy, and measure the intensity of pain.

Objective This study is to investigate the prognostic significance of serum CA15 3 detection in patients with breast carcinoma Methods Blood samples were obtained from 145 breast carcinoma patients, ECL(electrochemiluminescence) technology was used to measure CA15 3 levels Results CA15 3 levels were elevated in breast carcinoma patients with recurrence or metastasis ( ? 2=27 865, P

Objective To investigate the distribution status of coal-burning fluorosis (endemic fluorosis) areas in Luoyang and to provide scientifc evidence for making strategies in prevention and control. Methods In 2006, a household per village was chosen to carry the general survey so as of disease condition, living habits and housing structure among 941 coal-burning pollution fluorine sickness natural villages in Yanshi, Mengjin, Xin'an, Luanchuan counties and Geely area which were under the jurisdiction of Luoyang. In the general survey, the sampled village having a population of more than 500 person was considered as a major survey village, and water fluoride, 8 - 12 year-old child fluorine spot on tooth and the urinary fluoride were surveyed. Water fluoride and the child urinary fluoride determination used the fluoride ion selective electrode method, and the children's dental fluorosis used Dean method. Results The endemic fluorosis of Luoyang existed 742 in endemic fluomsis villages, compared with history, a decrease of 199 in number. Ninety-six point seven per cent( 142 543/147 419) of the households were consuming smoke-free coal. Households using intact kitchens accounted for 93.6%( 137 919/147 419). Of which 63.0%(86 889/137 919) of kitchens were mixed up with bedrooms. Total 125 060 people were using coal- fired furnace for heating, of which 87.8%(109 802/125 060) had smoke-free facilities, 12.2%(15 258/125 060) had none. Among 52 endemic villages with population of more than 500 people surveyed, a total of 183 water samples were collected, 2 had water fluoride exceeding 1.0 rag/L, the highest water fluoride being 1.04 rag/L, averaging 0.39 mg/L Sixteen villages had a prevalence rate of dental fluorosis for children less than 30.00%, accounting for 30.8% (16/52), 36 endemic villages the prevalence of dental fluorosis detection rate of more than 30.00%, accounting for 69.2%(36/52). Twenty-thrce villages had a dental fluorosis index greater than 0.6, severe dental fluorosis was not found. Real-time measurement of 1408 urine samples of children aged 8 - 12 showed that urine fluoride highest value 6.88 nag/L, the minimum value of 0.10 mg/L, geometric mean 1.10 mg/L. The prevalence rate of dental fluorosis for children was 36.06%. Conclusions In Luoyang city, numbers of coal-burning endemic fluorosis villages are less than before, children's dental fluorosis has significantly declined, however some people still use kitchens connecting with bedrooms and lack smoke-free facilities, they need to be educated to change lifestyle and improve furnace to reduce soot fluoride pollution.
