Post traumatic depression (PTD) is a serious complication after traumatic brain injury, with high incidence rate; PTD seriously affects the rehabilitation, outcome and quality of life of patients. Due to unclear pathogenesis of PTD, effective treatments have not yet been found in clinical practice. Repetitive transcranial magnetic stimulation (rTMS), as a new non-invasive neuroregulatory technique, has been used in major depression disorder (MDD). Few clinical evidence on PTD treated by rTMS is noted and optimal rTMS treatment regimen has not yet been defined.This article reviews the clinical studies of rTMS in PTD in recent years, with a view to provide references for clinical application.

Objective:To study the effects of FLASH irradiation (FLASH-RT) and conventional irradiation (CONV-RT) on gene expression profile in mouse liver, in order to provide theoretical basis of the potential mechanism of FLASH-RT.Methods:A total of 11 C57BL/6J male mice were divided into healthy control group (Ctrl group), CONV-RT group and FLASH-RT group according to random number table method. Mouse abdomen was treated with 12 Gy CONV-RT or FLASH-RT. Then the mice were killed by neck removal, and the liver tissues were collected to extract total RNA for transcriptome sequencing (RNA-Seq) that was then analyzed by bio-informatics analysis to investigate the changes of gene expression profiles. The mRNA expression levels of Stat1, Irf9 and Rela were verified by quantitative real-time PCR assay.Results:1 762 differentially expressed genes (DEGs) were identified in group FLASH-RT vs. CONV-RT. Among them, 660 genes were up-regulated and 1 102 genes were down-regulated. 1 918 DEGs were identified in groups FLASH-RT vs. Ctrl. Among them, 728 genes were up-regulated and 1 190 genes were down-regulated. 1 569 DEGs were identified in group CONV-RT vs. Ctrl. Among them, 1 046 genes were up-regulated and 523 genes were down-regulated. According to Gene Ontology (GO) analysis, these DEGs from groups FLASH-RT vs. CONV-RT were involved in various functions including defense response to virus, other organisms in cell components, adenylyltransferase activity in molecular function activity. These DEGs from group FLASH-RT vs. Ctrl were involved in various functions including defense response to other oranisms, endoplasmic reticulum chaperone complex, double-stranded RNA binding and so on. These DEGs from group FLASH-RT vs. CONV-RT were involved in several Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways including influenza A, Herpes simplex infection and so on. These DEGs from group FLASH-RT vs. Ctrl were involved in several KEGG pathways including influenza A, NOD-like receptor signaling pathway. Stat1 was likely to be activated by FLASH radiation. The quantitative real-time PCR assay showed that FLASH-RT obviously increased the mRNA expressions of Stat1, Irf9 and Rela ( t=6.62, 2.11, 1.67, P<0.05). Conclusions:FLASH-RT and CONV-RT could alter gene expression profiles in mouse liver tissues, and these DEGs are involved in multiple radiobiological functional pathways. In comparison with CONV-RT, FLASH-RT induces a low level of liver injury, which may due to hypoxia radiation resistance.

Objective:To investigate the application of sentinel lymph node biopsy (SLNB) in early-staged cervical cancer by laparoscopy.Methods:It was a prospective, single-arm, single-center clinical study. Seventy-eight cases of cervical cancer patients were collected from July 2015 to December 2018 at the Fourth Hospital of Hebei Medical University. All the patients were injected with tracer into the disease-free block of cervical tissue after anesthesia by the same surgeon who learned sentinel lymph node (SLN) mapping technique in Memorial Sloan-Kettering Cancer Center, and underwent SLN mapping followed by complete pelvic lymphadenectomy. Moreover, all the dissected lymph nodes were stained with hematoxylin eosin staining (HE) pathological examination. Besides, the negative SLN on hematoxylin-eosin staining were detected by immunohistochemistry cytokeratin staining micro-metastasis. To analyze the distribution, detection rate, false negative rate the sensitivity and negative predictive value of the SLN in early-staged cervical cancer by laparoscopy, and explore the value of SLN mapping in predicting the lymph nodes metastasis in early-staged cervical cancer.Results:The overall detection rate of SLN in cervical cancer was 99% (77/78), bilateral detection rate was 87% (68/78). The average of 12.4 lymph node (LN) and 3.6 SLN were dissected for each patients each side. SLN of cervical cancer were mainly distributed in the obturator space (61.5%, 343/558), followed by external iliac (23.5%, 131/558), common iliac (7.3%, 41/558), para-uterine (3.8%, 21/558), internal iliac (2.2%, 12/558), para abdominal aorta (1.1%, 6/558), and anterior sacral lymphatic drainage area (0.7%, 4/558). Fourteen cases of LN metastasis were found among all 78 cases. There were a total of 38 positive LN, including 26 SLN metastasis and 12 none sentinel LN metastasis. Through immunohistochemical staining and pathological ultra-staging, 1 SLN was found to be isolated tumor cells (ITC), and 5 SLNs were found to be micro-metastases (MIC), accounting for 23% (6/26) of positive SLN. SLN mapping with pathological ultra-staging improved the prediction of LN metastasis in cervical cancer (2/14). Metastatic SLN mainly distributed in the obturator space (65%, 17/26), peri-uterine region (12%, 3/26), common iliac region (15%, 4/26), and external iliac region (8%, 2/26). The consistency of the diagnosis of lymph node metastasis by SLN biopsy and postoperative retroperitoneal lymph node metastasis showed that the Kappa value was 1.000 ( P<0.001), indicated that the metastasis status of SLN and retroperitoneal lymph node were completely consistent. The sensitivity, specificity, accuracy, false-negative rate, and negative predictive value of SLN biopsy in the diagnosis of lymph node metastasis were 100%, 100%, 100%, 0, and 100%, respectively. Conclusions:SLN in early-staged cervical cancer patients were mainly distributed in the obturator and external iliac space, pathalogical ultra-staging of SLN could improve the prediction of LN metastasis. Intraoperative SLN mapping is safe, feasible and could predict the state of retroperitoneal LN metastasis in early-staged cervical cancer. SLNB may replace systemic pelvic lymphadenectomy.
