Objective To explore the relationship between aggressive behavior with thyroid hormone or cortisol and in schizophrenic patients. Methods According to the past violence history and modified overt aggression scale( MOAS) weighted total scores,108 schizophrenic patients were divided into aggressive group ( n=69) and non-aggressive group( n=39) . Positive and Negative Syndrome Scale ( PANSS) total scores, serum thyroid hormone levels and cortisol concentration were compared between the two groups before and af-ter 2,4 weeks treatment. And correlations of PANSS and sub-scales scores,thyroid hormone levels and corti-sol concentration with MOAS weighted total scores and subscales scores were analyzed before these patients receiving treatment. Results Before treatment,total scores of PANSS,positive symptoms and general psy-chopathology scores in aggressive group((94.19±12.71),(23.77±4.94),(52.61±6.45))were higher than that in non-aggressive group ((83.26±11.21),(21.36±7.10),(45.49±6.84)) and these differences were significant(P<0.05). But the difference of PANSS total scores after 2,4 weeks treatment between the two groups was not significant (P>0. 05 ) . Free thyroxine ( FT4 ) level of aggressive group ( ( 14. 41 ± 3. 58 ) pmol/L) was higher than that of non-aggressive group ((12.95±2.66)pmol/L) before treatment and the difference was significant(P<0.05) . Meanwhile,there was no significant differences between the two groups in thyrotropic-stimulating hormone(TSH),free triiodothyronine(FT3),total triiodothyronine(TT3) and total thyroxine( TT4) levels( all P>0.05) . After 2 or 4 weeks treatment,the differences between the two groups in TSH,FT3,FT4,TT3,TT4 levels were not significant(P>0.05). The differences between the two groups of cortisol concentration were not significant before and after 2,4 weeks treatment(P>0.05) . MOAS weighted to-tal scores were positively correlated with PANSS total scores,negative symptoms scores,general psychopathol-ogy scores and level of FT4,and their r values were 0.471,0.204,0.531,0.239(all P<0.05). Verbal aggres-sion was positively correlated with PANSS total scores,positive symptoms scores and general psychopathology scores,and their r values were 0.213,0.215,0.292(P<0.05). Auto-aggression was positively correlated with PANSS total scores and general psychopathology scores,and their r values were 0.278,0.382(P<0.05) . Psy-chical aggression was positively correlated with PANSS total scores,negative symptoms scores,general psy-chopathology scores and level of FT4,and their r values were 0.361,0.193,0.338,0.276(P<0.05). Conclusion The total scores of PANSS,positive symptoms,general psychopathology scores,level of FT4 and their variances can reflect severity of aggression and predict aggressive behavior in schizophrenic patients. Concen-tration of cortisol is not associated with aggressive behavior and can not be used as a predictor of aggressive behavior in schizophrenic patients.

OBJECTIVE To observe the effect of baicalin on Aβ25-35 induced learning and memory deficits and changes in autophagy-related genes in mice so as to explore the related mechanisms of Alzheimer disease (AD) treatment . METHODS C57 mice were administered with 3μL Aβ25-35 3 mmol·L-1 by intracerebroventricular injection to establish an AD model. Baicalin was given by intracerebroventricular injection at the dose of 25, 50 and 100 mg · kg-1 for 15 d, respectively. The total distance and the central grid residence time were measured in the open-field test. The escape latency and the time to reach the platform were monitored in the Morris water maze trial. The autophagic vacuoles in the hippocampus of the mice were observed by transmission electron microscopy before the protein expressions of microtu?bule-associated protein 1 light chain 3 (LC3) and Beclin1 in brain tissue were analyzed by Western blot?ting assay. RESULTS Intracerebroventricular injection of Aβ25-35 could reduce the total distance from (3984±321)cm to (2790±306)cm and extend central grid residence time from (3.6±1.2)s to (8.8±2.9)s in the open-field test. The escape latency of water maze also increased from (22.0 ± 1.9)s to (38.8 ± 2.2)s. Autophagic vacuoles or late autophagic vacuoles and increased Beclin1 and LC3 and protein level were observed in the hippocampus after Aβ25-35 injection. Intraperitoneal injection of Baicalin 50 and 100 mg · kg-1 for fifteen consecutive days extended the total distance in open-field test to (3705 ± 337)cm and (3968 ± 448)cm, respectively, while the central grid residence time was reduced to (5.6 ± 1.8)s and (3.9±1.5)s, respectively. The total time taken to reach the platform in water maze test was reduced to (28.6± 1.9)s, (22.9 ± 1.7)s. Mitochondrial swelling, vacuolar membrane structure or autophagic vacuoles were visible in the hippocampus. LC3 and Beclin1 protein expression was significantly up-regulated(P<0.01). CONCLUSION Baicalin shows protective effect against Aβ25-35 induced learning and memory deficits, and this effect may be related to the activation of autophagy in the mouse hippocampus.

Tumor brings great threat to human public health. In recent years, incidence rate and mortality of tumor were rapidly increased in the world. Anti-tumor therapies have undergone the development of cytotoxic therapy, targeted therapy, and immunotherapy. Among them, tumor immunotherapy is rapidly developed and becomes an important anti-tumor therapy in recent years, although it also brings some related side effects. Tumor microenvironment (TME) is composed of immune cells, vascular vessels, fibroblasts, the extracellular matrix, etc. TME significantly affects the efficacy of immunotherapy. Macrophages in the TME are named as tumor associated macrophages (TAMs). Recently, increasing studies have shown that TAMs play an important role in the regulation of tumor immunity, especially in tumor immune surveillance and immune escape. Currently, more and more anti-tumor immunotherapy strategies targeting TAMs are at the development stage. Based on the important role of TAMs in the TME and their potential as therapeutic targets in tumor immunotherapy, we first reviewed the subtypes and functions of TAMs, as well as the roles of TAMs in tumors. Furthermore, we summarized the research progress on anti-tumor strategies targeting TAMs and the current status of drug targeting TAMs. The current review will provide new ideas and novel insights for tumor immunotherapy.

In order to investigate expression of novel genes HC56, HC70 and HC90 mapped on chromosome 17p13.3 in human leukemic cells, HC56, HC71 and HC90 genes expression was examined in cells from 35 patients with acute leukemias and 4 leukemic cell lines by using semi-quantitative RT-PCR with incorporation of alpha(32)P dATP, betaM2 gene as endogenous control. The results showed that HC90 gene expression level was lower in patients with acute lymphocytic leukemia and T lymphocytic leukemic cell line Jurkat than that in normal control. Low-level HC71 gene expression was detected in acute myeloid leukemia. There was no expression difference in HC56 between leukemic cells and normal blood cells. It was concluded that both HC70 and HC90 genes were aberrantly expressed in human leukemic cells.

HCAP1 is a novel hepatic cancer related gene located on human chromosome 17p13.3. The loss of heterozygosity occurred at 17p13.3 in various human cancers. In order to investigate the effects of exogenous HCAP1 gene products on cell proliferation of T lymphoma Jurkat cell line, HCAP1 gene! was transfected into Jurkat cells mediated by liposome, and the cells stably expressing exogenous HCAP1 were screened with G418. The effects of HCAP1 products on cell proliferation were assessed by viable cell count, cell growth curve and colony formation assay in soft agar. The results showed that the HCAP1 transgenic Jurkat cells displayed slow growth rate, extended doubling time and reduced colony formation capability, as compared with the cells transfected with pBK/CMV empty vector (P < 0.01). It is concluded that exogenous HCAP1 gene products could inhibit the proliferation of Jurkat cells.

Pancreatic cancer is a highly malignant tumor with a poor prognosis. It is very hard to treat pancreatic cancers for their high heterogeneity, complex tumor microenvironment, and drug resistance. Currently, gemcitabine plus nab-paclitaxel, capecitabine and FOLFIRINOX are standard chemotherapy for resectable or advanced metastatic pancreatic cancer. Considering the limited efficacy and toxic side effects of chemotherapy, targeted and immune drugs have gradually attracted attention and made some progress. In this article, we systematically reviewed the chemotherapeutic drugs, targets and related targeted drugs, and immunotherapy drugs for pancreatic cancer.

OBJCTIVE:
To study the clinical effect of surgery combined with chemotherapy and radiotherapy in children with central primitive neuroectodermal tumor (cPNET), as well as the risks factors for poor prognosis.
METHODS:
A retrospective analysis was performed for the clinical data of 42 children who were diagnosed with cPNET from June 2012 to September 2018.
RESULTS:
The 42 children had a median overall survival (OS) time of 2.0 years and a median event-free survival (EFS) time of 1.3 years; the 1-, 3-, and 5-year OS rates were 76.2%±6.6%, 41.4%±8.7%, 37.3%±8.8% respectively, and the 1-, 3-, and 5-year EFS rates were 64.3%±7.4%, 32.7%±8.0%, 28.0%±8.1% respectively. The univariate analysis showed that there were significant differences in the OS and EFS rates among the children with different patterns of surgical resection, chemotherapy cycles, and risk grades (P<0.05), and there was also a significant difference in the OS rate between the children receiving radiotherapy and those not receiving radiotherapy (P<0.05). The multivariate Cox regression analysis showed that chemotherapy cycles and risk grade were independent influencing factors for EFS and OS rates (P<0.05). The EFS and OS rates increased with the increase in chemotherapy cycles and the reduction in risk grade.
CONCLUSIONS
Multimodality therapy with surgery, chemotherapy, and radiotherapy is an effective method for the treatment of cPNET in children. Early diagnosis and treatment and adherence to chemotherapy for as long as possible may improve EFS and OS rates.

OBJECTIVE:
To investigate the effect of bevacizumab in the treatment of children with optic pathway glioma (OPG).
METHODS:
A retrospective analysis was performed for the clinical data of 30 children with OPG who underwent chemotherapy. According to whether bevacizumab was used, they were divided into conventional chemotherapy (carboplatin, vincristine and etoposide) group with 12 children and combined chemotherapy (bevacizumab, carboplatin, vincristine and etoposide) group with 18 children. The children were followed up to 6 months after chemotherapy, and the two groups were compared in terms of visual acuity and tumor size before and after chemotherapy and adverse reactions during chemotherapy.
RESULTS:
The combined chemotherapy group had a significantly higher proportion of children achieving tumor regression than the conventional chemotherapy group (P<0.05), while there were no significant differences between the two groups in the proportion of children with improved visual acuity or adverse reactions (P>0.05). No chemotherapy-related death was observed in either group.
CONCLUSIONS
Bevacizumab combined with conventional chemotherapy can effectively reduce tumor size. Compared with conventional chemotherapy, such combination does not increase adverse reactions and can thus become a new direction for the treatment of OPG in children.

Objective:To explore the effect of neutrophil-lymphocyte ratio (NLR) at the initial visit on the survival of children with newly diagnosed medulloblastoma (MB).Methods:This was a case-control study involving 61 children with newly diagnosed MB at the Department of Pediatrics, Beijing Shijitan Hospital, Capital Medical University from August 2018 to January 2020 .The blood cell counts, lymphocyte subsets and immunoglobulin in the periphe-ral blood were measured to calculate NLR at the initial visit.Based on the cut-off value determined by receiver opera-ting characteristic (ROC) curve, patients were divided into high NLR group (≥ 2.07, n=21) and low NLR group (<2.07, n=40). The progression-free survival (PFS) and overall survival (OS) between 2 groups were analyzed by the Kaplan-Meier method, followed by Log- rank test.The correlation between NLR at the initial visit with clinical characteristics, lymphocyte subsets and immunoglobulin of children with newly diagnosed MB was analyzed.Differences between groups were compared by the Chi- square test, Mann- Whitney U test and independent sample t test. Results:The survival analysis showed that the relapse rate (38.1% vs.10.0%, χ2=6.879, P=0.016) and mortality rate (19.0% vs.0, χ2=8.154, P=0.011) were significantly higher in high NLR group than those of low NLR group.PFS (12 months vs.19 months, χ2=9.775, P=0.002) and OS (19 months vs.20 months, χ2=8.432, P=0.004) were significantly shorter in high NLR group than those of low NLR group.No significant differences in clinical characteristics were detected between groups (all P>0.05). Compared with low NLR group, the percentage of T lymphocyte[(67.93±6.37)% vs.(73.38±8.08)%, t=2.886, df=48.865, P=0.006], T helper cells (Th)[(30.86±5.53)% vs.(34.29±7.44)%, t=2.037, df=51.981, P=0.047], and T suppressor cells (Ts)[(27.39±5.50)% vs.(30.84±6.58)%, t=2.164, df=47.581, P=0.035] were significantly lower in high NLR group.Spearman correlation analysis showed a negative correlation between NLR and T lymphocyte count ( r=-0.303, P=0.018), and Ts lymphocyte count ( r=-0.260, P=0.043). Conclusions:Children with newly diagnosed MB expressing a high level of NLR had a poor prognosis, which may be associated with T lymphocyte and Ts lymphocyte.
