Objective: To analyze the characteristics of human papillomavirus (HPV) infection and the distribution of HPV subtypes in Shijiazhuang, Hebei Province, and to explore the application evaluation of multiple PCR capillary electrophoresis fragment analysis for HPV typing test. Methods: A population-based cross-sectional study was conducted among 434 women (age range 17 to 74 years old, 260 patients and 174 physical examinations) included from May to August 2022 in Hebei General Hospital. HPV typing was detected by multiple PCR-capillary electrophoresis fragment analysis. Using the multiple fluorescence quantitative PCR kit as a reference, Chi-square test was used to analyze the diagnostic effect of multiple PCR-capillary electrophoresis fragment analysis, and the consistency was analyzed by Kappa value. Results: The total HPV infection rate was 45.85%(199/434), including 35.48% (154/434) of high-risk HPV (HR-HPV), 3.92% (17/434) of low-risk HPV (LR-HPV), 6.45% (28/434) of HR-HPV and LR-HPV mixed infection, 27.88% (121/434) of single type HPV and 17.97% (78/434) of multi type HPV. HPV52 (9.68%, 42/434), HPV16 (6.91%, 30/434), and HPV58 (6.91%, 30/434) are common HPV subtypes. The positive rate of physical examination was 45.40% (79/174), which was slightly lower than that of patients 46.15% (120/260), there was no significant difference (χ2=0.024,P>0.05). The highest infection rate in the 17-30 age group was 54.76% (46/84), and there was no statistical difference among the age groups(χ2=4.123,P>0.05). The sensitivity and specificity of multiplex PCR capillary electrophoresis fragment analysis were 92.96% and 94.04%, respectively, and Kappa value was 0.870, with the multiplex fluorescent quantitative PCR as the reference. Conclusion: HPV infection may appear younger, and the positive rate of HR-HPV infection is the highest, with HPV52, 16, 58 as the main infection subtypes. The detection results of multiplex PCR capillary electrophoresis fragment analysis method are highly consistent with those of multiplex fluorescent quantitative PCR method, which is suitable for HPV DNA typing.

Associations between various lipid components and premature myocardial infarction: a cross-sectional study / 中华心血管病杂志

Objective: Hyperlipidemia is closely related to premature acute myocardial infarction (AMI). The present study was performed to explore the correlation between various blood lipid components and the risk of premature AMI. Methods: This is a cross-sectional retrospective study. Consecutive patients with acute ST-segment elevation myocardial infarction (STEMI), who completed coronary angiography from October 1, 2020 to September 30, 2022 in our hospital, were enrolled and divided into premature AMI group (male<55 years old, female<65 years old) and late-onset AMI group. Total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), non-HDL-C, lipoprotein (a) (Lp (a)), apolipoprotein B (ApoB), apolipoprotein A-1 (ApoA-1), non-HDL-C/HDL-C and ApoB/ApoA-1 were analyzed. The correlation between the above blood lipid indexes and premature AMI was analyzed and compared by logistic regression, restricted cubic spline and receiver operating characteristic curve (ROC). Results: A total of 1 626 patients with STEMI were enrolled in this study, including 409 patients with premature AMI and 1 217 patients with late-onset AMI. Logistic regression analysis showed that the risk of premature AMI increased significantly with the increase of TG, non-HDL-C/HDL-C, non-HDL-C, ApoB/ApoA-1, TC and ApoB quintiles; while LDL-C, ApoA-1 and Lp (a) had no significant correlation with premature AMI. The restricted cubic spline graph showed that except Lp (a), LDL-C, ApoA-1 and ApoB/ApoA-1, other blood lipid indicators were significantly correlated with premature AMI. The ROC curve showed that TG and non-HDL-C/HDL-C had better predictive value for premature AMI. Inconsistency analysis found that the incidence and risk of premature AMI were the highest in patients with high TG and high non-HDL-C/HDL-C. Conclusion: TG, non-HDL-C/HDL-C and other blood lipid indexes are significantly increased in patients with premature AMI, among which TG is the parameter, most closely related to premature AMI, and future studies are needed to explore the impact of controlling TG on incidence of premature AMI.

Analysis of genotypes on 850 newborns with SLC26A4 single-allele mutation and the phenotypes of those with second variant / 中华耳鼻咽喉头颈外科杂志

Objective: To clarify the phenotypes of the newborns with SLC26A4 single-allele mutation in deafness genetic screening and second variant; to analyze the SLC26A4 genotype and hearing phenotype. Methods: 850 newborns born in Beijing from April 2015 to December 2019 were included and there were 468 males and 382 females. They received genetic deafness screening for 9 or 15 variants, with the result of SLC26A4 single-allele mutation. Firstly, three step deafness gene sequencing was adopted in this work, i.e., the first step was "SLC26A4 gene whole exons and splice sites" sequencing; the second step was "SLC26A4 gene promoter, FOXI1 gene and KCNJ10 gene whole exons" sequencing; and the third step was detection for "SLC26A4 gene copy number variation". Secondly, we collected the results of newborn hearing screening for all patients with the second mutation found in the three step test, and conducted audiological examinations, such as acoustic immittance, auditory brainstem response and auditory steady state response. Thirdly, for novel/VUS mutations, we searched the international deafness gene database or software, such as DVD, ClinVar and Mutation Taster, to predict the pathogenicity of mutations according to the ACMG guideline. Lastly, we analyzed the relationship between genotype and phenotype of newborns with SLC26A4 single allele mutation. Results: Among 850 cases, the median age of diagnosis was 4 months. In the first step, 850 cases were sequenced. A total of 32 cases (3.76%, 32/850) of a second variants were detected, including 18 cases (2.12%, 18/850) with identified pathogenic variants; 832 cases were sequenced and 8 cases of KCNJ10 gene missense variants were detected among the second step. No missense mutations in the FOXI1 gene and abnormal SLC26A4 gene promoter were detected; the third step sequencing results were all negative. Genotypes and hearing phenotypes included 18 cases combined with the second clear pathogenic variant, 16 cases (16/18) referred newborn hearing screening and 2 cases (2/18) passed in both ears; degree of hearing loss consisted of 18 profound ears (18/36), 13 severe ears (13/36) and 5 moderate ears (5/36); audiogram patterns comprised 17 high frequency drop ears (17/36), 14 flat ears (14/36), 3 undistinguished ears (3/36), and 2 U shaped ears (2/36); 11 cases underwent imaging examination, all of which were bilateral enlarged vestibular aqueduct. As for 22 cases of other genotypes, all passed neonatal hearing screening and the hearing diagnosis was normal, including 9 cases with VUS or possibly novel benign variants, 8 cases with KCNJ10 double gene heterozygous variants, and 5 cases with double heterozygous variants. Conclusions: The probability of individuals with SLC26A4 single-allele variant who merge with a second pathogenic variant is 2.12%, all of which are SNV, which can provide scientific basis for the genetic diagnosis and genetic counseling of SLC26A4 variants. Those who have merged with second pathogenic variant are all diagnosed with sensorineural hearing loss. Patients with KCNJ10 gene mutations do not manifest hearing loss during the infancy, suggesting the need for further follow-up.

Effect of reperfusion injury following different ischemic duration on skeletal muscle in rats / 中华创伤杂志

Objective:To investigate effect of reperfusion injury following different ischemic duration on skeletal muscle in rats.Methods:A model of ischemia/reperfusion injury (IRI) was established by unilateral clamping femoral artery and additional application of tourniquet in skeletal muscle of hind limbs in 35 male Wsitar rats. According to different ischemia time, the animals were assigned to 2-hour ischemia and 24-hour reperfusion (I2R24 group), 2.5-hour ischemia and 24-hour reperfusion (I2.5R24 group), 3-hour ischemia and 24-hour reperfusion (I3R24 group), 4-hour ischemia and 24-hour reperfusion (I4R24 group) and sham group, with 7 rats per group. At the end of reperfusion, gastrocnemious tissues and plasma samples were collected and analyzed. The ratio of wet ∶ dry weight (W/D) was used to measure muscle edema. The assay of 3-(4, 5-Dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) was conducted to evaluate muscle viability. HE staining was executed to observe histopathological changes. Immunofluorescence staining was performed to assess the levels of C1q, C3b/c, tissue factor (TF), fibrinogen (FN), bradykinin receptor 1 (BR1), BR2, vascular cell adhesion molecule-1 (VCAM-1), E-selectin, fibrinogen-like protein-2 (FGL-2) and myeloperoxidase (MPO) in muscle tissues. ELISA method was used to determine the concentrations of interferonγ (IFN-γ), interleukin7 (IL-7), IL-18, macrophage inflammatory1α (MIP-1α) and monocyte chemotactic protein 1 (MCP-1) in plasma.Results:With prolongation of ischemia time and subsequent reperfusion, tissue edema became severe gradually. The ratio of W/D was 5.3±0.2, 6.1±0.3, 6.9±0.2, 7.6±0.3 in I2R24, I2.5R24, I3R24 and I4R24 groups, higher than that in sham group (4.5±0.1) (all P<0.01). Muscle viability got decreased gradually. Muscle viability was (62.4±3.5)%, (45.3±3.3)%, (35.4±3.4)%, (27.1±5.9)% in I2R24, I2.5R24, I3R24 and I4R24 groups, lower than that in sham group［(93.8±7.2)%］(all P<0.01). Histopathological changes became aggravated gradually. The most severe group was I4R24 group, with the most severe myocyte injury, interstitial edema and extensive inflammatory infiltration, followed by I3R24, I2.5R24 and I2R24 groups in order. There was normal structure integrity and neatly arranged myocyte in sham group. Meanwhile, levels of C1q, C3b, FN, BR1, VCAM-1, E-selectin and FGL-2 got increased gradually. The highest levels for these factors were seen in I4R24 group, followed by I3R24 group, I2.5R24 group, I2R24 group and sham group in order. The rough ratio of the number of positive MPO cells/total cell number under high lens (×200) were increased gradually, with the highest level in I4R24 group, followed by I3R24 group, I2.5R24 group, I2R24 group and sham group in order. However, expression of TF and BR2 were not altered significantly among the groups. Plasma levels of INF-γ, IL-7, IL-18, MIP-1α and MCP-1 elevated gradually with prolongation of ischemia time (all P<0.01). The sequence was the sham group, I2R24 group, I2.5R24 group, I3R24 group and I4R24 groups for levels of these factors from low to high (all P<0.01). Conclusion:Reperfusion after prolongation of ischemia duration can increase the activation of complement, coagulation, kinin and endothelial cells as well as the release of inflammatory factors, and thus aggravate the degree of skeletal muscle tissue injury.

Preoperative hydronephrosis predicts adverse pathological features and postoperative survival in patients with high-grade upper tract urothelial carcinoma

ABSTRACT Purpose: Epidemiological studies reported conflicting results about preoperative hydronephrosis in upper tract urothelial carcinoma (UTUC). This study aimed to investigate the association between preoperative hydronephrosis and pathologic features and oncologic outcomes in patients with UTUC treated by radical nephroureterectomy (RNU). Materials and Methods: This was a retrospective, single-center cohort study of 377 patients treated by RNU without perioperative chemotherapy between January 2001 and December 2014. Logistic regression, Cox regression, and survival analyses were performed. Results: Among the 226 patients with high-grade UTUC, 132 (58%) had preoperative hydronephrosis. Multivariable logistic regression revealed that hydronephrosis was independently associated with advanced pT stage (P=0.017) and lymph node or lymphovascular invasion (P=0.002). Median follow-up was 36 months (interquartile range: 20-48 months). The 3- and 5-year overall survival (OS) rates in patients with hydronephrosis were significantly lower than in those without hydronephrosis (both P <0.001). The 3- and 5-year cancer-specific survival (CSS) rates in patients with hydronephrosis were significantly lower than in those without hydronephrosis (both P=0.001). Hydronephrosis was independently associated with OS and CSS (P=0.001 and P=0.004, respectively). Among the 151 patients with low-grade UTUC, hydronephrosis was not associated with pathologic features and postoperative survival. Conclusions: Preoperative hydronephrosis was significantly associated with adverse pathologic features and postoperative survival in patients with high-grade UTUC.

High resolution 3D intraosseous vascular model of the scaphoid bone reconstructed by micro CT / 解剖学报

[Abstract] Objective The purpose of this study is to construct a high-resolution model focusing on the vascular pattern of the scaphoid by using micro CT and to provide anatomical reference for the daily clinical use. Methods The lead-based contrast was perfused from the brachial artery and then the scaphoid bone was harvested. 3D models of the scaphoid bones were constructed by using micro CT to show how arteries distributed in and on the bones. Results The arteries on the surface stretched from the distal radius covered with scaphoid fossa to the radial side of the waist and then head back to the distal ulna along the dorsoradial ridge, formed like a letter “Ⅴ”. The arteries gathered at the inflection point of the letter “Ⅴ” and the dorsal region. The tubercle region was anastomosed extensively with 3 to 5 major intraosseous vessels originated from the extraosseous vessels covering the waist and the tubercle. There are only 1 to 2 major intraosseous vessels entering the bone via a long route from the ulnar side. The vessels running in the scapholunate ligament didn’t spilt into any intraosseous branches. Conclusion The superficial vascularity formes a “Ⅴ”-like pattern. The inflection point of the letter “Ⅴ” and the dorsal region display a dense vascularization and these vessels contributed a lot to the intraosseous vascularity.

Astrocytic GABA Receptors in Mouse Hippocampus Control Responses to Behavioral Challenges through Astrocytic BDNF / 神经科学通报·英文版

Major depressive disorder (MDD) is a common mood disorder that affects almost 20% of the global population. In addition, much evidence has implicated altered function of the gamma-aminobutyric acid (GABAergic) system in the pathophysiology of depression. Recent research has indicated that GABA receptors (GABARs) are an emerging therapeutic target in the treatment of stress-related disorders such as MDD. However, which cell types with GABARs are involved in this process is unknown. As hippocampal dysfunction is implicated in MDD, we knocked down GABARs in the hippocampus and found that knocking down these receptors in astrocytes, but not in GABAergic or pyramidal neurons, caused a decrease in immobility in the forced swimming test (FST) without affecting other anxiety- and depression-related behaviors. We also generated astrocyte-specific GABAR-knockout mice and found decreased immobility in the FST in these mice. Furthermore, the conditional knockout of GABARs in astrocytes selectively increased the levels of brain-derived neurotrophic factor protein in hippocampal astrocytes, which controlled the decrease in immobility in the FST. Taken together, our findings contribute to the current understanding of which cell types expressing GABARs modulate antidepressant activity in the FST, and they may provide new insights into the pathological mechanisms and potential targets for the treatment of depression.

Serum of 52 patients with confirmed lung adenocarcinoma was collected before and after surgery, and serum of 32 healthy subjects was also collected. The levels of CMTM6 and PD-L1 in peripheral blood before and after surgery were measured and analyzed by ELISA. Chi-square test was used to analyze the relationship between CMTM6 expression and clinicopathological features; Kaplan-Meier method and Log-Rank test were used to analyze the survival data of patients. Results: CMTM6 was widely expressed in lung adenocarcinoma tissues; 30% of the tumor tissues showed an up-regulation as compared with para-cancer tissues, and 70% showed no difference. CMTM6 expression was associated with clinical stage and distant metastasis (all P<0.05), but not significantly associated with age, gender, tumor size, and T stage (P>0.05). Kaplan-Meier survival analysis showed the survival rate of patients with high CMTM6 expression was significantly lower than those with stable expression (P=0.014), and among patients at stage Ⅲ, the survival rate of patients with high CMTM6 expression was significantly lower than those with stable CMTM6 expression (P=0.001). Cox regression model analysis of multiple factors showed CMTM6 expression was an independent risk factor for the prognosis of patients with lung adenocarcinoma. CMTM6 expression in pre-surgery serum, post-surgery serum and healthy donors’serum showed statistically significant differences (P<0.05), which was significantly correlated with tumor size and age of the patients. Spearman correlation analysis showed a significant correlation between serum CMTM6 and PD-L1 expression level (r=0.623, P<0.01). Conclusion: CMTM6 is an independent risk factor for the prognosis of lung adenocarcinoma patients. It plays an important role in the occurrence and development of lung adenocarcinoma and it is a potential tumor suppressor gene.

Biological function and mechanism of CMTM family / 中国肿瘤生物治疗杂志

@# CMTM家族作为一个新的基因家族，在免疫、生殖等系统以及多种肿瘤的发病机制中起到重要作用。CMTM家族中， CMTM1可影响细胞增殖，导致肿瘤发生；与非小细胞肺癌（NSCLC）患者的化疗耐药和预后有关。CMTM2通过AP-1、CREB通 路一定程度上影响HIV-1转录，同时在男性生殖系统中起重要作用。CMTM3等位基因失活或甲基化使其丧失对细胞增殖的负 性调控能力，是胃癌独立的预后指标。CMTM4调控细胞周期影响肿瘤细胞增殖，通过对PD-L1的协同保护参与免疫逃逸。 CMTM5在许多肿瘤中沉默表达，参与肿瘤发生发展相关的信号通路。CMTM6协同PD-L1参与免疫逃逸，是潜在的免疫治疗靶 点。CMTM7在NSCLC中通过Rab5控制EGFR-AKT信号影响肿瘤发展，且与胃癌发展相关。CMTM8通过MARVEL区域影响 EGFR和相关信号通路，调控细胞增殖、分化和凋亡等。上述重要发现，为研究肿瘤的发生发展及肿瘤基因治疗提供了新思路。
