ABSTRACT

AIM:One of the important characteristics of the occurrence and development of triple-negative breast cancer(TNBC)is dysregulated cell metabolism.The aim of this study is to investigate the mechanism of pyruvate dehydrogenase E1 subunit alpha 1(PDHA1),a key enzyme component in aerobic glycolysis,affecting the proliferation,metastasis and invasion of TNBC.METHODS:(1)The expression levels of PDHA1 in breast cancer tissues and adja-cent tissues were analyzed by UALCAN database,KM-plotter database,Gene MANIA database and TCGA database.The expression of PDHA1 was compared according to tumor pathological stage,subtype classification and breast cancer bio-markers.The function of PDHA1 in TNBC was explored by gene enrichment analysis.(2)Immunohistochemistry assays were used to detect the expression of PDHA1 in human TNBC tissue and adjacent tissue samples.(3)Stable PDHA1 knockout and PDHA1 rescue TNBC MDA-MB-231 cells were constructed.The proliferation of MDA-MB-231 cells was de-tected by colony formation assay and cell counting assay.The regulatory effect of PDHA1 on the invasion and migration of MDA-MB-231 cells was detected by in vitro scratch assay and Transwell migration assay.RESULTS:Database analysis showed that the group with high PDHA1 expression in breast cancer had shorter survival and worse prognosis.In clinical specimens,the expression of PDHA1 in cancer tissues was higher than that in adjacent normal tissues.Knockout of PDHA1 inhibited the proliferation,metastasis,invasion and epithelial-mesenchymal transition of MDA-MB-231 cells.CONCLUSION:PDHA1 is overexpressed in TNBC,and it promotes cell proliferation and facilitates TNBC metastasis through the epithelial-mesenchymal transition pathway.

ABSTRACT

Objective: To examine the safety and efficacy of the uniportal video-assisted thoracoscopic decortication in treatment of drug-resistant tuberculosis empyema. Methods: From January 2018 to December 2020, 122 cases of tuberculous empyema treated by decortication in Department of Surgery, Wuhan Pulmonary Hospital were retrospectively analyzed, including 100 males and 22 females, aged(M(IQR)) 29.5(28.0) years (range: 13 to 70 years). According to the surgical approach and drug resistance, patients with drug-resistant tuberculosis who underwent uniportal video-assisted thoracoscopic decortication were included in group A (n=22), and those who underwent thoracotomy decortication were included in group B (n=28). Drug-sensitive patients who underwent uniportal video-assisted thoracoscopic decortication were included in group C (n=72). There was no statistical difference in the baseline data of the three groups (P>0.05). The operation, early postoperative recovery, and prognosis-related indicators were compared among three groups by Kruskal-Wallis test and χ2 test by Mann-Whitney U test and Bonferroni method between groups A and B, groups A and C. Results: The intraoperative blood loss of group A, group B, and group C was 200(475) ml, 300(200) ml, and 225(300) ml, respectively. There was no significant difference in intraoperative hemorrhage (H=2.74, P=0.254) and treatment outcome (χ2=4.76, P=0.575) among the three groups. Compared with group B, the operation time of group A (302.5(187.5) minutes vs. 200.0(60.0) minutes, U=171.0, P=0.007) and postoperative pulmonary reexpansion duration (4.5(3.0) months vs. 3.0 (2.2) months, U=146.5, P=0.032) were longer, and the postoperative drainage duration (9.5(7.8) days vs. 13.0(10.0) days, U=410.0, P=0.044), and the postoperative hospitalization time (12.0(7.8) days vs. 14.5(4.8) days, U=462.2, P=0.020) were shorter. There was no significant difference in complications between group A and group B (63.6%(14/22) vs. 71.4%(20/28), χ2=0.34, P=0.558). Compared with group C, the postoperative drainage duration of group A (9.5(7.8) days vs. 7.0(4.0) days, U=543.5, P=0.031), the postoperative hospitalization time (12.0(7.8) days vs. 9.0(4.0) days, U=533.0, P=0.031) and postoperative pulmonary reexpansion duration (4.5(3.0) months vs. 3.0(2.0) months, U=961.5, P=0.001) were longer. The operation time (302.5(187.5) minutes vs. 242.5(188.8) minutes, U=670.5, P=0.278), and complications (63.6%(14/22) vs. 40.3%(29/72), χ2=3.70, P=0.054) were not different between group A and group C. Conclusions: For drug-resistant tuberculous empyema, the uniportal video-assisted thoracoscopic decortication can achieve the same good therapeutic effect as drug-sensitive tuberculous empyema, and it is as safe as thoracotomy. At the same time, it has the advantage of minimally invasive and can accelerate the early postoperative recovery of patients.

ABSTRACT

Objective: To verify the feasibility and accuracy of the transanal multipoint full-layer puncture biopsy (TMFP) technique in determining the residual status of cancer foci after neoadjuvant therapy (nCRT) in rectal cancer. Methods: Between April 2020 and November 2022, a total of 78 patients from the Beijing Chaoyang Hospital of Capital Medical University, the Beijing Friendship Hospital of Capital Medical University, the Qilu Hospital of Shandong University, the Zhongnan Hospital of Wuhan University with advanced rectal cancer received TMFP after nCRT participated in this prospective multicenter trial. There were 53 males and 25 females, aged (M(IQR)) 61 (13) years (range: 35 to 77 years). The tumor distance from the anal verge was 5 (3) cm (range: 2 to 10 cm). The waiting time between nCRT and TMFP was 73 (26) days (range: 33 to 330 days). 13-point transanal puncture was performed with a 16 G tissue biopsy needle with the residual lesion as the center. The specimens were submitted for independent examination and the complications of the puncture were recorded. The consistency of TMFP and radical operation specimen was compared. The consistency of TMPF with clinical remission rates for the diagnosis of complete pathological remission was compared by sensitivity, specificity, negative predictive value, positive predictive value and accuracy. Statistical analysis between groups was performed using the χ2 analysis, and a paired χ2 test was used to compare diagnostic validity. Results: Before TMFP, clinical complete response (cCR) was evaluated in 27 cases. Thirty-six cases received in vivo puncture, the number of punctures in each patient was 13 (8) (range: 4 to 20), 24 cases of tumor residue were found in the puncture specimens. The sensitivity to judgment (100% vs. 60%, χ2=17.500, P<0.01) and accuracy (88.5% vs. 74.4%, χ2=5.125, P=0.024) of TMFP for the pathologic complete response (pCR) were significantly higher than those of cCR. Implement TMFP based on cCR judgment, the accuracy increased from 74.4% to 92.6% (χ2=4.026, P=0.045). The accuracy of the in vivo puncture was 94.4%, which was 83.3% of the in vitro puncture (χ2=1.382, P=0.240). Overall, the accuracy of TMFP improved gradually with an increasing number of cases (χ2=7.112, P=0.029). Conclusion: TMFP is safe and feasible, which improves the sensitivity and accuracy of rectal cancer pCR determination after nCRT, provides a pathological basis for cCR determination, and contributes to the safe development of the watch and wait policy.

ABSTRACT

Objective To screen antigen targets for immunotherapy by analyzing over-expressed genes, and to identify significant pathways and molecular mechanisms in esophageal cancer by using bioinformatic methods such as enrichment analysis, protein-protein interaction (PPI) network, and survival analysis based on the Gene Expression Omnibus (GEO) database.Methods By screening with highly expressed genes, we mainly analyzed proteins MUC13 and EPCAM with transmembrane domain and antigen epitope from TMHMM and IEDB websites. Significant genes and pathways associated with the pathogenesis of esophageal cancer were identified using enrichment analysis, PPI network, and survival analysis. Several software and platforms including Prism 8, R language, Cytoscape, DAVID, STRING, and GEPIA platform were used in the search and/or figure creation.Results Genes MUC13 and EPCAM were over-expressed with several antigen epitopes in esophageal squamous cell carcinoma (ESCC) tissue. Enrichment analysis revealed that the process of keratinization was focused and a series of genes were related with the development of esophageal cancer. Four genes including ALDH3A1, C2, SLC6A1,and ZBTB7C were screened with significant P value of survival curve.Conclusions Genes MUC13 and EPCAM may be promising antigen targets or biomarkers for esophageal cancer. Keratinization may greatly impact the pathogenesis of esophageal cancer. Genes ALDH3A1, C2, SLC6A1,and ZBTB7C may play important roles in the development of esophageal cancer.

ABSTRACT

OBJECTIVE@#To investigate the clinical features and genetic etiology of a case of Turner syndrome (TS) with rapidly progressive puberty.@*METHODS@#A child who had presented at the Pediatric Endocrinology Clinic of the Shenzhen People's Hospital on January 19, 2022 was selected as the study subject. Clinical data of the child were collected. Peripheral blood sample of the child was subjected to chromosomal microarray analysis (CMA) and multiple ligation-dependent probe amplification (MLPA). Previous studies related to TS with rapidly progressive puberty were retrieved from the CNKI, Wanfang Data Knowledge Service Platform, Boku, CBMdisc and PubMed databases with Turner syndrome and rapidly progressive puberty as the keywords. The duration for literature retrieval was set from November 9, 2021 to May 31, 2022. The clinical characteristics and karyotypes of the children were summarized.@*RESULTS@#The child was a 13-year-and-2-month-old female. She was found to have breast development at 9, short stature at 10, and menarche at 11. At 13, she was found to have a 46,X,i(X)(q10) karyotype. At the time of admission, she had a height of 143.5 cm (< P3), with 6 ~ 8 nevi over her face and right clavicle. She also had bilateral simian creases but no saddle nasal bridge, neck webbing, cubitus valgus, shield chest or widened breast distance. She had menstruated for over 2 years, and her bone age has reached 15.6 years. CMA revealed that she had a 58.06 Mb deletion in the Xp22.33p11.1 region and a 94.49 Mb duplication in the Xp11.1q28 region. MLPA has confirmed monosomy Xp and trisomy Xq. A total of 13 reports were retrieved from the CNKI, Wanfang Data Knowledge Service Platform, Boku, CBMdisc and PubMed databases, which had included 14 similar cases. Analysis of the 15 children suggested that their main clinical manifestations have included short stature and growth retardation, and their chromosomal karyotypes were mainly mosaicisms.@*CONCLUSION@#The main clinical manifestations of TS with rapidly progressive puberty are short stature and growth retardation. Deletion in the Xp22.33p11.1 and duplication in the Xp11.1q28 probably underlay the TS with rapid progression in this child, which has provided a reference for clinical diagnosis and genetic counselling for her.

ABSTRACT

Objective:To seek any correlation between cortical activity and the swallowing of dysphagia patients with infratentorial stroke, and to observe any effect of three-needle acupuncture of the tongue on such activity.Methods:Thirty infratentorial stroke survivors with dysphagia were randomly divided into a tongue three-needle group and a sham acupuncture group, each of 15. Functional near-infrared spectroscopy was used to monitor changes in the concentration of oxygenated hemoglobin (ΔHbO 2) at rest, during acupuncture (or sham acupuncture), during real or sham electro-acupuncture, and at rest after the acupuncture or sham acupuncture treatment. The Modified Rankin Scale, a Penetration-Aspiration Scale (PAS), and the Functional Oral Intake Scale were employed to assess overall functional disability and the swallowing of both groups. Results:At rest the average ΔHbO 2 concentrations recorded in the left primary motor cortex, the left dorsolateral prefrontal cortex and the left premotor cortex in both groups were positively correlated with the PAS scores. During the acupuncture ΔHbO 2 concentration in the right inferior frontal gyrus and the left middle temporal gyrus increased significantly in the tongue three-needle group. It decreased significantly in the left somatosensory cortex and the left primary motor cortex. Conclusion:Three-needle acupuncture of the tongue induces changes in cortical activity in infratentorial stroke survivors with dysphagia, suggesting a potential technique for improving disordered swallowing.

ABSTRACT

In addition to primary diseases, critically ill patients often suffered from multiple functional disorders, including pulmonary dysfunction. Pulmonary rehabilitation can effectively improve the lung and overall function of patients, which need assistance of relevant examinations. Point-of-care ultrasound (POCUS) can not only help to diagnose, evaluate, monitor and treat the disease faster, more accurate and safer, but also reduce the adverse events resulting from handling, activities and radiation, which is applied more extensively in critical patients accepting pulmonary rehabilitation.

ABSTRACT

Objective:To investigate the expression of circhipk3 in microglial cells in heat-induced neurological injury, and to preliminary analyze the effect of circhipk3 on microglial polarization in heat-induced neurological injury.Methods:Mice were randomly (random number) divided into a control group and a heat radiation disease 0.8 h group (HS 0.8), a heat radiation disease 8h group (HS 8), and a heat radiation disease 24 h group (HS 24). By establishing a mouse model of heat shock (HS), heat-damaged brain tissue was obtained, microglia were isolated and RNA was extracted. Quantitative PCR method was used to detect M1 and M2 marker molecules in microglia, and to evaluate the polarization direction and type of microglia. The expression level of circhipk3 was detected in microglial cells in heat-induced neurological injury, and the effect of circhipk3 on microglial polarization was further elucidated by intervening the expression of circhipk3 in microglial cells.Results:The expression of CD45 and CD11-b in the HS 8 group was significantly higher than that in the control group [(4.41±0.18) vs. (1±0.15), P=0.000], [(3.47±0.19) vs (1±0.15), P=0.000] , and the CD45 and CD11-b of the HS 24 group was significantly lower than that of the HS 8 group [(1.34±0.15) vs. (4.41±0.18), P=0.000], [(1.38±0.21) vs. (3.47±0.19), P= 0.001]. At the same time, the expression of CD206, FIZZ and Arg1 in the HS 8 group started to increase compared with the control group [(1.59±0.16) vs. (1±0.12), P=0.014], [(1.62±0.15) vs. (1±0.15), P=0.002 ], [(2.23±0.28) vs. (1±0.19), P=0.004], and CD206, FIZZ, and Arg1 in the HS 24 group were significantly higher than those in the control group [(2.67±0.20) vs. (1±0.12), P=0.002], [(2.19±0.15) vs. (1±0.15), P=0.000], [(3.04±0.18) vs. (1±0.19), P=0.001]; circhipk3 mimicis significantly increased the expression of Arg1 [(7.26± 0.06) vs. (3.86±0.06), P=0.000]; at the same time, circhipk3 inhibitor promoted the expression of CD45 and HO-1 [(2.96±0.03) vs. (1.63±0.09), P=0.000], [(2.52±0.10) vs. ( 1.30±0.02), P=0.000]. Conclusions:Microglial cells are predominantly M1-type in early neurological injury of heat radiation disease. HO-1 may be one of the microglial M1-type markers. The high expression of circhipk3 in microglial cells mainly promotes its transformation to M2 type.

ABSTRACT

OBJECTIVE@#To study the correlation of genome-wide distribution of 6-methyladenine (6mA) of DNA in chorionic tissues from abortuses with monosomy 21.@*METHODS@#Genomic DNA was extracted from chorionic samples from four abortuses with monosomy 21 and four without. After quality and purity test, partial DNA was subjected to chromatin immunoprecipitation with anti-6mA antibody, and then identified by sequencing. The sequencing data was analyzed by using bioinformatic software for the difference in 6mA between the two groups.@*RESULTS@#Analysis of read peaks suggested that the control group have much more 6mA genes (n=4607) compared with the experiment group (n=1059). For chromosome 21, this difference is even more pronounced (8032 vs. 1769). Above results suggested that the level of 6mA modification in monosomy 21 is low. Gene ontology enrichment analysis and KEGG pathway enrichment analysis indicated that the absence of 6mA genes in monosomy 21 is closely related to the growth and development of embryo.@*CONCLUSION@#The 6mA modification of human genes may play a similar role to 5-methylcytosine (5mC) modification during the growth and development of embryos.

According to inclusion criteria, 62 consecutive patients receiving neoadjuvant chemotherapy prior to elective surgery following SEMS for complete obstructive left hemicolon cancer from Beijing Chaoyang Hospital of Capital Medical University (n=31), Qilu Hospital of Shandong University (n=14), the Third Xiangya Hospital of Central South University (n=13), Zhongnan Hospital of Wuhan University (n=2), the Fourth Hospital of Hebei Medical University (n=2) between December 2015 and December 2017 were prospectively enrolled in this study. Patients were divided into neoadjuvant chemotherapy group and elective surgery group according to the investigator's clinical experience and patient's preference. Patients in the elective surgery group received surgery within one to two weeks after SEMS placement without neoadjuvant chemotherapy. Those in the neoadjuvant chemotherapy group received 2 cycles of CapeOX or 3 cycles of mFOLFOX6 neoadjuvant chemotherapy within one to two weeks after SEMS placement, and then underwent surgery within 3 weeks after finishing neoadjuvant chemotherapy. Data between groups were compared using Student t-test, chi-square analysis or Fisher exact test analysis, including basic clinical informations, operational conditions and postoperative complications. The adverse reactions during the neoadjuvant chemotherapy were recorded. Surgical difficulty was assessed using visual analog scales ranging from 1 to 10, where 1 represented the lowest and 10 the highest degree of surgical difficulty, as judged by the surgeon.@*RESULTS@#The study included 38 males and 24 females with mean age of (64.8±8.8) years. The clinical baseline data between 2 groups were not significantly different (all P>0.05) except the average time interval between SEMS and surgery was significantly longer in neoadjuvant chemotherapy group [(61.6±13.5) days vs. (10.4±5.2) days, t=16.679, P0.05).@*CONCLUSION@#Neoadjuvant chemotherapy prior elective surgery following SEMS is a relatively safe and feasible approach in the treatment for obstructive left hemicolon cancer, and is associated with less stoma, more laparoscopic surgery, shorter operative time, less blood loss, lower surgical difficulty, and faster postoperative recovery as compared with conventional elective surgery.
