Objective To explore the time of application of hemoperfusion (HP) for the treatment of acute serious organophosphorus pesticide (ASOPP). Methods One hundred and four patients with ASOPP were randomly divided into two groups, 46 patients accepted traditional treatment(control group), 58 patients were treated with traditional treatment and HP (HP group). The patients in HP group were again divided into three groups according the different time of treatment (time of beginning HP after poisoning), the 4-8 hours group (HP-1 group, 27 patients), the 9-16 hours group (HP-2 group, 19 patients), the 17-32 hours group (HP-3 group, 12 pafients).Tbe coma period, the dosage of atropine, the time of regaining the vitality of cholinesterase, the time of hospitalization and the rate of fatality and curing among groups were observed. Results The coma period, the dosage of atropine, the time of regaining the vitality of cholinesterase, the time of hospitalization and the rate of fatality of the HP group were less than those of the control group (P<0.05). Compared with HP-1 group, the eoma period, the dosage of atropine, the time of regaining the vitality of eholinesterase and the time of hospitalization of the HP-2 group and the HP-3 group were higher (P<0.05), but the difference of the rate of fatality and curing between the HP-1 group and the other HP groups was not statistically significant (P>0.05). The difference of all of the above indicators between HP-2 group and HP-3 group was not statistically significant (P>0.05). Conclusion Application of hemoperfusion among 4-32 hours after poisoning for the treatment of ASOPP can improve the efficacy of therapy, and the efficacy of application of hemoperfusion among 4-8 hours is the best.

Objective:To investigate the application of Aptima high-risk human papillomavirus (HR-HPV) E6/E7 mRNA (AHPV) and its genotyping (GT) in the risk assessment of low-grade squamous intraepithelial lesions (LSIL).Methods:The AHPV and its genotype (AHPV-GT) incervical exfoliated cells were detectedin 529 women with LSIL.The DNA-Based Hybrid Capture 2 HPV Test (HC2-HPV), colposcopy and cervical biopsy were performedsimultaneously.Results:① In 529 patients with LSIL, the positive rate of HC2-HPV in the group of ＜30 years old was significantly higher than that in the group of ≥30 years old (92.2％ vs 83.6％, P=0.026).There was no significant difference in AHPV positive rate among different age groups (82.5％ vs 77.7％, P=0.284).No significant difference of the genotyping (AHPV-GT) was detected between the two groups, either.In the 529 cases, 83 cases of HSIL+were confirmed by histology.81 cases (97.6％) were AHPV positive in the patients with HSIL+;② Compared with other 11 positive types of HR-HPV, the incidence of HSIL+in GT+ women increased significantly (P＜0.05).In the group ≥30 years old, the OR value of HSIL+exposure risk of AHPV16 positive women was the highest (141.00), which was significantly higher than that of 18/45+, GT +, AHPV + (P=0.005, 0.000, 0.000).However, in the group of ＜30 years old, the OR value of HSIL+exposure risk of AHPV16 positive women was 8.50, which showed no significant difference from that of 18/45+ and AHPV-(P=1.000, 0.070).③ In group over 30 years old, the specificity of detecting HSIL+by AHPV was higher than that by HC2-HPV (P＜0.05).There was no significant difference in detection specificity between AHPV and HC2-HPV in women under 30 years old.Conclusions:AHPV and its GT detection are reliable methods for colposcopic screening and risk stratification in women aged over 30 years old with LSIL, more attention should be focused on AHPV16 positive.Better biological markers should be explored for younger women.

On March 24, 2017, a patient with Von Hippel-Lindau syndrome (VHL) characterized by bilateral adrenal pheochromocytoma and pancreatic tumors was admitted to our hospital, who underwent simultaneous pancreatic body and tail tumor resection, bilateral adrenal tumor resection and Omentum transplantation of the right adrenal gland.Intraoperative hormone therapy was used. Part of the normal adrenal tissue was preserved and embedded in the omentum, but an adrenal crisis occurred on the first day after the operation.The hormone replacement was used. Postoperative hormone replacement therapy was performed for 6 months. After 4 years of follow-up, blood pressure was normal, no cortical dysfunction, no tumor recurrence or other related lesions appeared. The preserved part of adrenal tissue during simultaneous multi-organ tumor resection for such patients can reduce long-term hormone replacement after surgery and prevent late adrenal cortex dysfunction.

OBJECTIVETo evaluate the association between chemical exposure, DNA methylation status and gene-environment interactions in the development of childhood acute leukemia (AL).

METHODSFrom January 1st 2009 to December 31st 2010, an exploratory case-control study was conducted on childhood AL among children who were less than 15 years of age in Shanghai, China. A total of 131 patients with newly diagnosed AL were recruited from 3 Shanghai children hospitals. The controls selected from the same hospital were healthy children who attended the physical check-up held by the department of Children's Healthcare, or who visited the clinic of developmental pediatrics or orthopedics (excluding blood diseases and malignant tumors). 140 controls matched with cases in gender and age were included in this study. Chemical exposure were investigated by questionnaires, methylation specific polymerase chain reaction (MSP) was adopted to analyze the methylation or deletion status of 8 genes, and gene-environment interactions were analyzed by relative excess risk of interaction (RERI), attributable proportion of interaction (API) and synergy index (S).

RESULTSThere were 131 and 140 subjects in case and control group, who were aged (6.9 ± 3.8) and (6.9 ± 3.9) years old (t = 0.01, P = 0.911), respectively. After adjusting age and other potential confounding factors, chemical substances' exposure of children/mother/father were all significantly higher in cases than that in controls (Children: OR = 3.90, 95% CI: 1.69-9.02; Mother: OR = 2.71, 95% CI: 1.12-6.52; Father: OR = 1.91, 95% CI: 1.05-3.47). For the 8 genes analyzed, the methylation status of DAPK and PTEN and P73 in case group were significantly higher than that in control group (cases: 3.1% (4 cases), 16.0% (21 cases), 7.6% (10 cases); controls: 0.7% (1 case), 2.9% (4 cases), 0.7% (1 case); χ²: 7.11, 16.90, 11.38; P value: 0.029, 0.000, 0.003). The methylation status of P16 in case group was significantly lower than that in control group (cases: 3.8% (5 cases); controls: 8.6% (12 cases), χ² = 10.33, P = 0.007). The interactions of children chemical substances' exposure and 3 genes' (PTEN, P16 and P73) methylation status were probably existed after adjusted for confounding factors (PTEN: RERI = -7.01, API = -2.14, S = 0.24; P16: RERI = 4.08, API = 0.53, S = 2.59; P73: RERI = 4.32, API = 0.48, S = 2.19), we also found the potential interaction between maternal chemical substances' exposure and PTEN, P16 gene methylation status (PTEN: RERI = -1.30, API = -0.38, S = 0.65; P16: RERI = 1.70, API = 0.38, S = 1.97).

CONCLUSIONThe study suggested the strong combined effects of chemical substances exposure of children and abnormal methylation status were risk factors of childhood AL, and there existed different interaction between them, which may indicate the important role in the pathogenesis process of childhood AL.

OBJECTIVETo investigate the association between children's and their parents' lifestyles, household environmental exposures and risk of childhood acute leukemia (AL).

METHODSA 1:2 matched case-control study of childhood AL was conducted in Shanghai between April 2011 and January 2014. The study enrolled 66 cases aged < 15, diagnosed with AL and 132 controls matched by age, gender and residence. All of the controls had no hematological diseases or previous history of malignancy. Children who had been adopted and had congenital genetic syndromes such as Down's syndrome or a positive HIV test result were not eligible as either cases or controls. Information was obtained from standardized face-to-face interviews of their parents/guardians with detailed questions on demographic characteristics, lifestyle, and household environment. Conditional logistic regression models were used to analyze effecting factors of childhood AL, odds ratios (OR) and their 95% confidence intervals (CI) were calculated.

RESULTSAmong 198 cases, 66 cases were aged (5.0 ± 3.7) years old, and 132 controls were aged (6.0 ± 3.8) years old (t = 0.48, P = 0.523). The paternal drink frequencies of cases and controls were 57.6% (38/66), and 31.1% (41/132), respectively (χ² = 4.91, P = 0.027). And the frequencies of household insecticides usage in the last year in the two groups were 78.8% (52/66), and 65.2% (86/132) (χ² = 3.87, P = 0.049). Chemical exposure during childhood (OR = 4.76, 95% CI: 1.34-16.89), maternal exposure to chemicals (OR = 4.51, 95% CI: 1.65-12.33), household insecticides use during 0-3 years of child (OR = 2.90, 95% CI: 1.31-6.39), and renovating after their children's birth (OR = 3.12, 95% CI: 1.26-7.74) were associated with an increased risk of childhood AL and these differences between the cases and the controls have statistical significance. Besides, we found that frequent contaction with other children during 0-3 years old (OR = 0.32, 95% CI: 0.15-0.69) and ventilation during sleeping in summer (OR = 0.43, 95% CI: 0.18-0.98) were associated with a decreased risk of childhood AL.

CONCLUSIONOur results support the association between children's and their parents' lifestyles, household environmental exposures and childhood AL.
