Objective To evaluate non-hazardous treatment efficiency of night soil in the three-grille mode septic tanks so as to give the evidence to government for policy-making. Methods One hundred and thirty normally runningthree-grille mode septic tanks were surveyed in five cities of Jiangsu Province in 2009. The fecal samples from first chamber and wastewater samples from third chamber were collected and examined for fecal coliform (FC) , parasite eggs including Schistosoma japonicum eggs, As-caris eggs and hookworm eggs, chemical oxygen demand ( COD), five-day chemical oxygen demand (BOD_5) and ammonia nitrogen (NH,-N) in lab. The data were analyzed by statistical software SPSS 13.0. Results The mean qualified rates of FC in the first chamber and third chamber of septic tanks were 3.1% and 100% respectively, showing significant difference (P <0.001). Hookworm eggs and Ascaris eggs were found in the first chamber of one and four septic tanks respectively and the density was one or two eggs in one hundred milliliter. The mean removal rates of FC, COD, BOD_5 and NH_3 -N were (99.96 ± 0.03) % , (60.69 ± 21.77) % , (60.13 ± 23. 20 ) % and (44. 14 ± 24.61) % , respectively. For the value of FC, COD, BOD, and NH_3 -N, there were significant difference between the first chamber and the third chamber (P_(FC) =0.000 1, P_(COD) =0.000 1, P_(BOD5) =0.000 1, P_(NH3-N) = 0.000 1, P < 0.001). Conclusion The treatment efficiency of septic tank could meet the sanitary standard for non-hazardous treatment of night soil, and it could use as a useful primary facility for human feces and urine treatment in rural areas.

Acute appendicitis represents one of the most common causes of acute abdomen that may warrant emergency surgery. Necrotizing fasciitis complicated by acute appendicitis is considered a rare complication with life-threatening implications. A 65-year-old man presented with abdominal pain, where a scan, revealed a perforated appendicitis complicated by an anterior abdominal wall collection. He underwent percutaneous drainage, but subsequently developed extensive necrotizing fasciitis requiring extensive debridement and reconstruction. The rapid progression of necrotizing fasciitis calls for early recognition and prompt intervention. The key management principles employed were broad spectrum antibiotics and aggressive surgical debridement. This case demonstrated the use of vacuum-assisted closure dressing and multidisciplinary care in wound healing and coverage. To ensure early diagnosis and intervention for acute appendicitis complicated by necrotizing fasciitis, a high degree of clinical suspicion and awareness of this complication is required.

OBJECTIVETo estimate the significance of the adjustment of acute lymphoblastic leukemia (ALL) risk group by monitoring minimal residual disease(MRD).
METHODTotally 285 children ALL patients who were diagnosed and systematically treated according to CCLG-2008 in Institute of Hematology and Blood Diseases Hospital, CAMS and PUMC, from April 2008 to August 2011 were prospectively selected. Among these cases, 62.8% (n = 179) were boys and 37.2% (n = 106) were girls and the median age was 5.3(0.5-14.0). The patients who were at high-risk group initially were excluded. The grouping of cases: the patients were divided into two groups according to the dates of initial diagnosis. Group I had 126 patients who were initially diagnosed between April 2008 and December 2009 in whom therapeutic regimen was not adjusted by reassignment of risk group by MRD. Group II had 159 patients who were initially diagnosed between January 2010 and August 2011 whose therapeutic regimen was adjusted by reassignment of risk group by MRD at specific time (33rd day of induction chemotherapy and 12 weeks after the beginning of chemotherapy). MP-FCM Coulter FC-500 was used in the detection of MRD.
RESULTAmong these 285 patients, 94.0% (n = 268) were diagnosed as B-lineage acute lymphoblastic leukemia and 6.0% (n = 17) were T-lineage acute lymphoblastic leukemia. In group I, 61.9% (n = 78) patients belonged to low-risk group, 38.1% (n = 48) median-risk; in group II, before the adjustment, the rates of the low-risk group and median-risk group were 68.6% (n = 109) and 31.4% (n = 50) , respectively, while after the adjustment they were altered to 53.5% (n = 85) and 39.6% (n = 63) , furthermore 6.9% (n = 11) patients went into the high-risk group. Both groups were followed up for 2.5 years after their diagnoses, the disease of 7.4% (n = 21) patients relapsed, and the rates of two groups were 12.7% (n = 16) and 3.1% (n = 5) respectively, P = 0.009. The rate of serious infection (such as sepsis, pulmonary infection) of all these patients was 32.3% (92/285) , there was no significant difference between the two groups [28.6% (36/126) vs.35.2% (56/159) , P = 0.392]. The mortality of all these patients was 6.7% (19/285) , and that of group I was higher than that of group II [10.3% (13/126) vs. 3.8% (6/159) , P = 0.044]. The 2.5 years overall survival (OS), event-free survival (EFS) and disease-free survival (DFS) of group I were all lower than those of group II in Kaplan-Meier survivorship analysis (all P < 0.05). The two groups were followed up for 2.5 years after their diagnoses, after elimination of the confounding influence of sex, age, FAB subtype, WBC count, ratio of blast cells in bone marrow at diagnosed, chromosome karyotype and fusion gene, reassignment of risk group by MRD was used to calculate the OS, EFS and DFS of ALL patients (all P < 0.05). After the adjustment the risk group was more significant in the assessment of prognosis.
CONCLUSIONThe reassignment of risk group in low and median risk groups children with acute lymphoblastic leukemia by MRD did not increase the rate of serious infection but could reduce the relapse rate and mortality, and was beneficial to increase the patients' OS, EFS and DFS.

Current studies have shown that centromere protein F (CENPF) was overexpressed in hepatocellular carcinoma (HCC) and might be involved in the pathogenesis of HCC. Specifically, due to the very large molecular weight (358 kDa) of CENPF full length protein, only CENPF knock-down, but not overexpression models, were applied currently to explore the carcinogenicity of CENPF in HCC. Whether CENPF overexpression is a cause or an effect in HCC remains to be illustrated. We aimed to establish a CENPF overexpression cell model using CRISPR/dCas9 synergistic activation mediator (SAM) system with lentiMPHv2 and lentiSAMv2 vectors to explore the role of CENPF overexpression in HCC. Single guide RNAs (sgRNAs) that specifically identify the transcription initiation site of CENPF gene were synthesized and inserted into the lentiSAMv2 plasmid. Huh-7 and HCCLM3 cells were first transduced with lentiMPHv2 and then selected with hygromycin B. The cells were then transduced with lentiSAMv2 carrying specific sgRNA for CENPF gene, followed by blasticidin S selection. The mRNA and protein detection results of Huh-7 and HCCLM3 cells screened by hygromycin B and blasticidin S showed that the endogenous overexpression of CENPF can be induced by sgRNA1 and sgRNA4, especially by sgRNA4. By using the CRISPR/dCas9 technique, stable cell models with overexpressed CENPF were successfully constructed to explore the role of CENPF in tumorigenesis, which provides a reference for the construction of cell models overexpressing large molecular weight protein.
