[Objective]To investigate primary and secondary transfer of exfoliated cells from human hands on non-porous substrates such as plastic steering wheel or computer mouse.[Methods]DNA detection sensitivity and detection limit for mixed DNA profiling were examined to understand our laboratory's ability to test for trace DNA.Forensic swabs were used to collect samples from volunteers'one-hour-long unwashed hands,substrates touched by volunteers'immediately or 30 min following shaking hands,and individual A's daily-use substrates touched by individual B and then by individual A again.Simulations were conducted to assess the potential for introduction of another person's exfoliated cells from hands into routine casework samples.[Results]Our laboratory can obtain a full DNA profile from as little as 0.020 ng of DNA and detect minor components in a 1:9 mixed DNA sample.85%of samples from unwashed hands yielded a full DNA profile.Primary transfer of a full DNA profile was found in 77%of substrates touched by volunteers'dominant hand 30 min after hand washing,allowing differentiation between good and poor shedders,with no significant difference in genders and substrate types.75%of substrates touched 30 min after hand washing and then immediately following handshaking yielded the other individual's DNA profile(secondary transfer),with the number of short tandem repeat(STR)loci detected ranging from 0 to 23;the percentage and number decreased substantially when the substrates were touched 30 minutes later.No foreign DNA was detected in routine casework samples with introduced exfoliated cells from hands.When two individuals took turns touching items with their hands,the major contributor to the DNA profile was not always the individual who made the last contact.[Conclusions]Primary and secondary DNA transfer can be detected on non-porous substrates,and based on the deposit of hand exfoliated cells,individuals can be categorized as good or poor shedders,which is an important factor affecting detection of DNA transfer.Besides considering the laboratory's DNA detection sensitivity,if DNA is detected on substrates by hand contact,we need to take into account the potential for secondary transfer at different levels of activity when interpreting the results.

Objective:To evaluate the role of minimal residual disease (MRD) monitoring during early induction therapy for the treatment of childhood acute lymphoblastic leukemia (ALL).Methods:This was a multicenter retrospective cohort study. Clinical data of 1 164 ALL patients first diagnosed between October 2016 and June 2019 was collected from 16 hospitals in South China Children′s Leukemia Group. According to MRD assay on day 15 of early induction therapy, they were divided into MRD<0.10% group, MRD 0.10%-<10.00% group and MRD≥10.00% group. According to MRD assay on day 33, they were divided into MRD<0.01% group, MRD 0.01%-<1.00% group and MRD≥1.00% group. Age, onset white blood cell count, central nervous system leukemia (CNSL), molecular genetic characteristics and other data were compared between groups. Kaplan-Meier method was used for survival analysis. Cox regression model was used to analyze prognostic factors.Results:Of the 1 164 enrolled patients, there were 692 males and 472 females. The age of diagnosis was 4.7 (0.5, 17.4) years. The white blood cell count at initial diagnosis was 10.7 (0.4, 1 409.0) ×10 9/L. Among all patients, 53 cases (4.6%) had CNSL. The follow-up time was 47.6 (0.5, 68.8) months. The 5-year overall survival (OS) and 5-year relapse-free survival (RFS) rates were (93.1±0.8) % and (90.3±1.1) %. On day 15 of early induction therapy, there were 466 cases in the MRD<0.10% group, 523 cases in the MRD 0.10%-<10.00% group and 175 cases in the MRD≥10.00% group. The 5-year OS rates of the MRD<0.10% group, MRD 0.10%-<10.00% group and MRD≥10.00% group were (95.4±1.0) %, (93.3±1.1) %, (85.4±2.9) %, respectively, while the RFS rates were (93.2±1.6) %, (90.8±1.4) %, (78.9±4.3) %, respectively ( χ2=16.47, 21.06, both P<0.05). On day 33 of early induction therapy, there were 925 cases in the MRD <0.01% group, 164 cases in the MRD 0.01%-<1.00% group and 59 cases in the MRD≥1.00% group. The 5-year RFS rates in the MRD 0.01%-<1.00% group was lowest among three groups ((91.4±1.2) % vs. (84.5±3.2) % vs. (87.9±5.1) %). The difference between three groups is statistically significant ( χ2=9.11, P=0.010). Among ALL patients with MRD≥10.00% on day 15 of induction therapy, there were 80 cases in the MRD <0.01% group on day 33, 45 cases in the MRD 0.01%-<1.00% group on day 33 and 45 cases in the MRD≥1.00% group on day 33. The 5-year RFS rates of three groups were (83.9±6.0)%, (67.1±8.2)%, (83.3±6.9)% respectively ( χ2=6.90, P=0.032). Univariate analysis was performed in the MRD≥10.00% group on day 15 and the MRD 0.01%-<1.00% group on day 33.The 5-year RFS rate of children with CNSL was significantly lower than that without CNSL in the MRD≥10.00% group on day 15 ((50.0±20.4)% vs. (80.3±4.4)%, χ2=4.13, P=0.042). Patients with CNSL or MLL gene rearrangement in the MRD 0.01%-<1.00% group on day 33 had significant lower 5-year RFS rate compared to those without CNSL or MLL gene rearrangement ((50.0±25.0)% vs. (85.5±3.1)%, χ2=4.06, P=0.044;(58.3±18.6)% vs. (85.7±3.2)%, χ2=9.44, P=0.002). Multivariate analysis showed that age ( OR=0.58, 95% CI 0.35-0.97) and white blood cell count at first diagnosis ( OR=0.43, 95% CI 0.27-0.70) were independent risk factors for OS. The MRD level on day 15 ( OR=0.55,95% CI 0.31-0.97), ETV6-RUNX1 fusion gene ( OR=0.13,95% CI 0.03-0.54), MLL gene rearrangement ( OR=2.55,95% CI 1.18-5.53) and white blood cell count at initial diagnosis ( OR=0.52,95% CI 0.33-0.81) were independent prognostic factors for RFS. Conclusions:The higher the level of MRD in early induction therapy, the worse the OS. The MRD levels on day 15 is an independent prognostic factor for RFS.The MRD in early induction therapy guided accurate risk stratification and individualized treatment can improve the survival rate of pediatric ALL.

Objective: To investigate the neural connections between Shenmen (HT7)-heart and the brain by observing the tracing viruses co-labeled brain nuclear groups after injection of the pseudorabies viruses (PRV), the reverse transsynaptic virus tracer carrying different fluorescent protein genes, into the myocardium and Shenmen (HT7) point, respectively.Methods: Pseudorabies virus 531 (PRV531) carrying the green fluorescent protein gene and pseudorabies virus 724 (PRV724) carrying the red fluorescent protein gene were injected into the left ventricular wall and Shenmen (HT7) point area of the left forelimb of six C57BL/6 mice, respectively. After 120 h, whole brain tissue was extracted under 4% paraformaldehyde perfusion to prepare brain sections. Neuronal co-labeling with the tracing viruses was observed under fluorescence microscopy. Results: Co-labeled signals from the mouse ventricular wall and Shenmen (HT7) point region were found at all levels of the mouse central nervous areas, such as the cerebral cortex, hypothalamus, midbrain, pons, and medulla oblongata. The number of co-labeled neurons was higher in the primary motor area, the hypothalamic paraventricular nucleus, the subceruleus nucleus, and the paramedian reticular nucleus. Conclusion: There is a neural connection between Shenmen (HT7), the heart, and the brain, which may be most closely related to the autonomic nervous system.

Owing to incurable castration-resistant prostate cancer (CRPC) ultimately developing after treating with androgen deprivation therapy (ADT), it is vital to devise new therapeutic strategies to treat CRPC. Treatments that target programmed cell death protein 1 (PD-1) and programmed death ligand-1 (PD-L1) have been approved for human cancers with clinical benefit. However, many patients, especially prostate cancer, fail to respond to anti-PD-1/PD-L1 treatment, so it is an urgent need to seek a support strategy for improving the traditional PD-1/PD-L1 targeting immunotherapy. In the present study, analyzing the data from our prostate cancer tissue microarray, we found that PD-L1 expression was positively correlated with the expression of heterogeneous nuclear ribonucleoprotein L (HnRNP L). Hence, we further investigated the potential role of HnRNP L on the PD-L1 expression, the sensitivity of cancer cells to T-cell killing and the synergistic effect with anti-PD-1 therapy in CRPC. Indeed, HnRNP L knockdown effectively decreased PD-L1 expression and recovered the sensitivity of cancer cells to T-cell killing in vitro and in vivo, on the contrary, HnRNP L overexpression led to the opposite effect in CRPC cells. In addition, consistent with the previous study, we revealed that ferroptosis played a critical role in T-cell-induced cancer cell death, and HnRNP L promoted the cancer immune escape partly through targeting YY1/PD-L1 axis and inhibiting ferroptosis in CRPC cells. Furthermore, HnRNP L knockdown enhanced antitumor immunity by recruiting infiltrating CD8+ T cells and synergized with anti-PD-1 therapy in CRPC tumors. This study provided biological evidence that HnRNP L knockdown might be a novel therapeutic agent in PD-L1/PD-1 blockade strategy that enhanced anti-tumor immune response in CRPC.

9.Grasping the basic principle and getting rid of the misunderstanding of clinical application of visual electrophysiological technology
Chinese Journal of Ocular Fundus Diseases 2020;36(11):829-832
Commonly clinical visual electrophysiological detection methods include flash ERG, pattern ERG, VEP and multifocal ERG, etc. These inspection methods play an important role in disease identification and visual function judgment. However, lacking of understand the basic principles of electrophysiological testing, misunderstandings of the clinician influence the choice of examination methods or interpretation of examination results. The understanding of the basic principles of electrophysiological testing and analysis of the causes of these misunderstandings have important clinical significance in the correct application of visual electrophysiological testing technology.

OBJECTIVE:
Our previous research showed that Naotaifang (a compound traditional Chinese herbal medicine) extract (NTE) has clinically beneficial effects on neurological improvement of patients with acute cerebral ischemia. In this study, we investigated whether NTE protected acute brain injury in rats and whether its effects on ferroptosis could be linked to the dysfunction of glutathione peroxidase 4 (GPX4) and iron metabolism.
METHODS:
We established an acute brain injury model of middle cerebral artery occlusion (MCAO) in rats, in which we could observe the accumulation of iron in neurons, as detected by Perl's staining. Using assay kits, we measured expression levels of ferroptosis biomarkers, such as iron, glutathione (GSH), reactive oxygen species (ROS) and malonaldehyde (MDA); further the expression levels of transferrin receptor 1 (TFR1), divalent metal transporter 1 (DMT1), solute carrier family 7 member 11 (SLC7A11) and GPX4 were determined using immunohistochemical analysis, real-time quantitative polymerase chain reaction and Western blot assays.
RESULTS:
We found that treatment with NTE reduced the expression levels of TFR1 and DMT1, reduced ROS, MDA and iron accumulation and reduced neurobehavioral scores, relative to untreated MCAO rats. Treatment with NTE increased the expression levels of SLC7A11, GPX4 and GSH, and the number of Nissl bodies in the MCAO rats.
CONCLUSION
Taken together, our data suggest that acute cerebral ischemia induces neuronal ferroptosis and the effects of treating MCAO rats with NTE involved inhibition of ferroptosis through the TFR1/DMT1 and SCL7A11/GPX4 pathways.
