Lie detection technology has been applied increasingly to investigate and solve criminal cases. This article explores the evolvement of lie detection technology in the ancient times and the application of the psychological and physiological parameters which have become more accurate with the introduction of modern polygraph. The cognitive exploration and the application of Event Related Potentials (ERPs), functional Magnetic Resonance Imaging (fMRI), and Event-Related functional Magnetic Resonance Imaging (E-R fMRI) have made detection technology focus on the brain activities, which produce more objective results by tracing the original state of lying. In summary, this article describes different types of lie detections, simple and complex, their working principles, the latest development, and the prospect of their application in forensic science.

Objective To explore the association of genotypes of human papillomavirus (HPV) with cervicitis, cervical intraepithelial neoplasia (CIN) and carcinoma in situ of cervix. Methods A total of 464 patients with cervical biology admitted to Hefei women and child health care hospital from October, 2014 to October, 2015 were selected. Among them, there were 242 cases of cervicitis, 222 cases of CIN (76 of group Ⅰ, 71 of group Ⅱ, and 66 of group Ⅲ), and 9 cases of cervical cancer. Hybrid chip technology was used to detect cervical secretions of patients, and 21 kinds of HPV DNA were typed according to histopathological biopsy. Results The HPV infection was found in 464 patients with cervical lesions. Among them, 354 cases (76.3%) had HPV infection with 232 cases (65.5%) of single HPV infection and 122 cases (34.5%) of multiple infections included. The rate of HPV infection was 64.9% in the group of cervicitis, while the rate was 86.8% in group I of CIN and in group II of CIN, the rate of HPV infection was 87.3%. Surprisingly, the HPV infection rate in group III of CIN was as high as 90.9%. The infection rate of HPV in the patients with CIN was significantly higher than those with cervicitis (P<0.001). All patients with cervical cancer were infected with HPV. Conclusions Persistent infection of high-risk HPV subtypes increases the hazard of cervical tumor and CIN. Therefore, genotyping of HPV DNA is helpful for screening and prediction of cervical cancer.

BACKGROUNDPopulation-based cancer registry collects the data on cancer incidence and mortality deaths from covered population to describe and survey the epidemics in certain areas. The aim of this study was to estimate the cancer incidence and mortality in Wuwei, Gansu province, Northwestern China from 2003 to 2012. The goal is to better understand cancer distribution and long-term development of cancer prevention and treatment in Wuwei.

METHODSData were collected from the Wuwei Cancer Registry between 2003 and 2012. In this registry, data from 46 cancer report centers were included in this analysis. Incidence/mortality rates, age-specific incidence/mortality rates, age-standardized incidence/mortality rates, and cumulative incidence/mortality rates were calculated. Totally, 9,836,740 person-years (5,110,342 for males and 4,726,398 for females) had been monitored over this time period. The gender ratio of male/female was 1.08:1. The number of new cancer cases and related deaths was 24,705 and 17,287 from 2003 to 2012, respectively.

RESULTSThe proportion of morphological verification was 74.43%. The incidence of cases identified through death certification only was 1.21%, and the mortality to incidence ratio was 0.70. The average crude incidence was 251.15/100,000 persons (310.61 and 186.87 for males and females per 100,000 persons, respectively). The age-standardized rates by Chinese standard population (ASR-China) and by world standard population (ASR-world) were 207.76 and 245.42 per 100,000 persons, respectively. The crude cancer mortality was 175.74/100,000 persons (228.34 and 118.86 for males and females per 100,000 persons). ASR for China and the world was 149.57 and 175.13/100,000 persons, respectively. The most common cancers and leading causes of cancer-related deaths in Wuwei were as follows: cancers of stomach, esophagus, liver, lung, colorectum, breast, cervix, lymphoma, blood (leukemia), brain, and central nervous system. In Wuwei, during 2003 and 2012, cancer incidence and mortality rates increased by 1.32% and 1.31%/year, respectively. During this time, colorectum cancer incidence and mortality rates increased by 2.69% and 7.54%/year, respectively, in Wuwei. The incidence and mortality of other gastric, esophageal, liver, and lung cancers also all increased.

CONCLUSIONSThe results of this study report a more accurate cancer burden among the population of Wuwei, China. Active research of cancers etiology and effective prevention should be established to reduce the incidence and mortality associated with cancers.

The aim of this study was to explore the clinical effect and complications of allogeneic peripheral blood stem cell transplantation (allo-PBSCT) in hematologic malignancies through retrospective analysis of 75 patients (42 male, 33 female; aged from 13 to 72 years old) received allo-PBSCT from HLA matched (n=61) or haploidentical donors (n=14). 75 patients included 35 patients with chronic myeloid leukemia (CML), 30 patients with acute myeloid leukemia, 5 patients with severe aplastic anemia, 3 patients with acute lymphocytic leukemia, one patients with multiple myeloma and one patients with paroxysmal nocturnal hemoglobinuria. Conditioning regimens were (1) Cy/TBI or Bu/Cy; (2) Cy/TBI+Ara-C; (3) fludarabine+TBI/or (CTX+ATG). Minimal residual disease has been monitored regularly by PCR and FISH. Patients received cyclosporine A and methotrexate or ATG and anti-CD25 monoclonal antibody and mycophenolate mofetil for graft-versus-host disease (GVHD) prophylaxis. Relapsing patients after transplantation received DLI and/or chemotherapy. Patient with CML were treated with imatinib. The results showed that 74 patients had hematopoietic reconstitution, and eventually converted to full donor chimerism by FISH or PCR-STR. The median time for the initial hematopoietic reconstitution was 15 (5-25) days. 46 out of 75 patients were alive and median duration was 23 (2-61) months. Among 29 dead patients, 9 died of disease relapse, 7 died of III-IV grade of acute GVHD and 7 died of severe infection (2 patients developed interstitial pneumonia). 9 out of 14 patients received haploidentical transplantation were alive, and the time of event-free survival was 30 (6-53) months, the mean survival time of 5 died patients was 7 (2-17) months. 16 patients were infected by cytomegalovirus, 2 of them died of interstitial pneumonia. None of them suffered from veno-occlusive disease in the liver. It is concluded that allo-PBSCT is effective to treat refractory hematologic diseases, and DLI/or chemotherapy should be used in the patients relapsing after transplantation.

ObjectiveTo study the effect and mechanism of Wuwei Xiaoduyin in treating rat renal mesangial cells （HBZY-1） induced by lipopolysaccharide （LPS） through the nuclear factor-κB （NF-κB） signaling pathway. MethodRat HBZY-1 cells were randomly assigned into the normal group， model group， benazepril （50 μmol·L^-1） group， and high- and low-dose （2.75 and 0.69 g·kg^-1） Wuwei Xiaoduyin groups. The normal group， model group， and benazepril group were treated with 10% normal rat serum， and the Wuwei Xiaoduyin groups with 10% medicated serum. Except the normal group， the other four groups were treated with LPS （100 ng·mL^-1） for modeling in vitro. The changes of cell morphology were observed under optical microscope. The expression of NF-κB p65 was detected by immunofluorescence （IF） method. Methyl thiazolyl tetrazolium （MTT） colorimetry was employed to detect cytotoxicity and cell proliferation. The levels of interleukin-1β （IL-1β）， intercellular adhesion molecule-1 （ICAM-1）， laminin （LN）， and fibronectin （FN） in cell supernatant were determined by enzyme-linked immunosorbent assay （ELISA）. The mRNA levels of IL-1β， FN， and NF-κB p65 were measured by real-time fluorescence quantitative PCR. The protein levels of phosphorylated inhibitor of NF-κB kinase β （p-IKKβ）， phosphorylated NF-κB inhibitor （p-IκBα）， and NF-κB p65 were determined by Western blot. ResultCompared with the normal group， the modeling increased cell proliferation （P<0.01）， elevated the levels of IL-1β， ICAM-1， LN， and FN in cell supernatant （P<0.01）， and up-regulated the mRNA levels of IL-1β， FN， and NF-κB p65 （P<0.01） and the protein levels of p-IKKβ， p-IκBα， and NF-κB p65 （P<0.01）. Such changes were recovered by benazepril and Wuwei Xiaoduyin （P<0.05， P<0.01）. ConclusionWuwei Xiaoduyin can mitigate the inflammatory injury of renal mesangial cells induced by LPS by inhibiting the NF-κB signaling pathway.

The increasing incidence of obesity and diabetes has made diabetic kidney disease （DKD） the main cause of chronic kidney disease and end-stage renal disease. Despite current pharmacological interventions for blood glucose control and renin-angiotensin system inhibition， the risk of kidney disease progression and complications remains high. At present， the pathogenesis of DKD has been clarified to be related to chronic inflammatory response， oxidative stress， glucose and lipid metabolism disorders， and hemodynamic abnormalities. According to recent studies， the programmed cell deaths （PCD） of renal intrinsic cells such as pyroptosis and necroptosis play a key role in the occurrence and development of DKD. Pyroptosis and necroptosis， the two newly discovered routes of PCD， can protect the hosts from being invaded by microbial pathogens， but their dysregulation is associated with multiple autoimmunity and autoinflammatory responses. Pyroptosis and necroptosis are closely interlinked and cross-regulated. Different from apoptosis， these two cellular suicide mechanisms cause membrane rupture and release of cell contents through their respective gasdermin D （GSDMD） and mixed lineage kinase domain-like protein （MLKL）， with damage-associated molecular patterns （DAMPs） and inflammatory cytokines like interleukin-1β （IL-1β） involved to trigger inflammation， and chronic inflammatory responses are key factors leading to the progression of DKD. Traditional Chinese medicine （TCM） has long been employed for the prevention and treatment of DKD and the resulting clinical outcomes are remarkable. TCM has been proved to exert a protective effect against DKD by affecting the expression of nucleotide oligomerization domain-like receptor protein 3 （NLRP3） inflammasome， receptor-interacting protein kinase 3 （RIPK3）， and MLKL. This paper reviewed the relationship of pyroptosis and necroptosis with DKD and its intervention with TCM.
