ABSTRACT
Objective:To compare surgery-related indicators, patient recovery status, perioperative complications and risk factors affecting the occurrence of postoperative grade Ⅲ or higher complications in patients undergoing laparoscopic gastric mesenchymal tumor surgery with different visceral fat areas.Methods:Clinical data of 116 patients with gastric interstitial tumor in Shaanxi Provincial People′s Hospital from April 2014 to June 2020 were retrospectively analyzed, including 44 male patients and 72 female patients, with patient aged from 25 to 88 years old and the mean age was (61.8±10.7) years, including 54 patients in the high VFA group and 62 patients in the low VFA group. SPSS 23.0 was used for statistical analysis, and t-test and χ2 test were applied to compare and analyze the patients′ surgery-related indexes, postoperative recovery status, complications within 30 d after surgery and differences in Clavien-Dindo classification of complications, while univariate and multifactorial analyses were used to study the factors affecting the occurrence of postoperative grade Ⅲ or higher complications. Results:Patients in the high VFA group had a higher body mass index than in the low VFA group, and the difference was statistically significant ( t=4.48, P<0.001); patients in the high VFA group had longer operative time ( t=2.88, P=0.005), more intraoperative bleeding ( t=2.17, P=0.032), longer period of fasting ( t=2.73, P=0.008), longer time for defecation ( t=4.46, P<0.001) and bowel movement ( t=4.62, P<0.001), and longer postoperative hospital stay ( t=3.43) compared with those in the low VFA group ( t=2.73, P=0.001), prolonged defecation ( t=4.46), prolonged bowel movement ( t=4.62), and prolonged postoperative hospitalization ( t=3.43), with statistically significant differences ( P<0.05); the incidence of postoperative complications was significantly higher in the high VFA group (31.4%) compared with the low VFA group (14.5%) ( χ2=4.78, P=0.029); among them, the incidence of postoperative pulmonary infection was significantly higher in patients in the high VFA group (12.9%) compared with those in the low VFA group (1.6%), and the difference between them was statistically significant ( χ2=4.16, P<0.05); while the differences in postoperative incision-related complications, anastomotic fistula, lower limb venous thrombosis, and intestinal obstruction were not statistically significant ( P>0.05). The incidence of postoperative complications above grade Ⅲ of the Clavien-Dindo complication classification was significantly higher in patients in the high VFA group (16.7%) compared with those in the low VFA group (4.8%), and the difference between the two was statistically significant ( χ2=4.35, P<0.05); univariate analysis revealed that operative time ≥300 min and increased VFA were the risk factors for postoperative grade Ⅲ or higher complications, while VFA was not an independent risk factor. Conclusion:Larger visceral fat area increases the difficulty of laparoscopic gastric mesenchymal tumor surgery operation, and also affects patients′ postoperative recovery, leading to increased postoperative complications, but VFA is not an independent risk factor affecting the occurrence of postoperative grade Ⅲ or higher complications in patients with gastric mesenchymal tumor.
ABSTRACT
Objective:To investigate the risk factors affecting the occurrence of perioperative complications in patients with locally progressive gastric cancer undergoing radical gastric cancer treatment.Methods:The clinical data of 129 patients with locally progressive gastric cancer from January 2017 to December 2019 in Shaanxi Provincial People′s Hospital were retrospectively analyzed, including 98 males and 31 females, with an age ranged from 27 to 79 years and a mean age of (60.61±10.00) years. The postoperative complications of 129 patients with gastric cancer were firstly counted, and then the relationship between clinical data such as patients′ general condition, intraoperative status and pathological indexes and the occurrence of perioperative complications was analyzed by using univariate analysis, and significant factors were included in the logistic regression model for multifactor analysis to study the independent risk factors for the occurrence of perioperative complications.Results:Of the 129 patients, 25 cases (19.38%) had postoperative complications, including 10 cases (7.75%) with Clavien-Dindo classification combined with grade Ⅲ or higher complications. The results of univariate analysis suggested ACCI score >4 (30.76% vs 68.00%, χ2=11.86, P=0.001), body mass index ≥25 kg/m 2 (24.03% vs 60.00%, χ2=12.18, P=0.001), and preoperative hypoproteinemia (17.30% vs 36.00%, χ2=4.25, P=0.039), vascular cancer embolism (14.42% vs 40.00%, χ2=7.70, P=0.006), operative time ≥ 400 min (26.92% vs 52.00%, χ2=5.84, P=0.016), intraoperative bleeding ≥ 400 mL (13.46% vs 44.00%, χ2=12.03, P=0.001) were risk factors for the development of perioperative complications in patients with locally progressive gastric cancer. Multifactorial analysis showed that ACCI score >4, body mass index ≥25 kg/m 2, preoperative hypoproteinemia, vascular cancer embolism, and intraoperative bleeding ≥400 mL were independent risk factors for the occurrence of perioperative complications in patients with locally progressive gastric cancer ( P<0.05). Conclusions:The occurrence of perioperative complications in locally progressive gastric cancer hands was closely associated with ACCI score, body mass index, preoperative hypoproteinemia, vascular cancer embolism and intraoperative bleeding. ACCI score is expected to be a predictor of the occurrence of perioperative complications in patients with locally progressive gastric cancer.
ABSTRACT
Objective:To analyze the cause of poor distance visual acuity after refractive rotationally asymmetric multifocal intraocular lens (IOL) implantation in cataract patients.Methods:The data were collected from patients who underwent cataract phacoemulsification combined with intraocular lens (refractive rotationally asymmetric multifocal intraocular lens, SBL-3) implantation at Beijing Aier Intech Eye Hospital from December 2016 to December 2018, and followed up for six months after operation. Standard logarithmic visual acuity chart was used to record uncorrected distance visual acuity, best corrected distance visual acuity, intermediate visual acuity, and near visual acuity. Defocus curve was drawn. The corneal topography, postoperative visual quality and intraocular lens centered or not were checked by Itrace.Results:Total 95 eyes of 70 patients were implemented by cataract phacoemulsification combined with regional refractive intraocular lens operation. Among them, uncorrected distance visual acuity of 16 eyes of 16 patients, were less than or equal to 0.6. The distance power zone of the intraocular lens of 7 patients were placed in the area of high corneal refractive power. Because of measurement error, reserved error, etc, the power of IOL in 7 patients had deviations. Farsightedness and dizziness occurred in 2 patients. The visual discomfort symptoms disappeared and vision improved through intraocular lens positioning.Conclusions:The poor quality of distance visual acuity is mainly caused by the coincidence of the distance power zone with the corneal high-refractive region, the deviation of the power of the intraocular lens, and the intraocular lens center shift. If the cornea has a high refractive area, the distance power zone should avoid to be placed in the same area. The intraocular lens should be reserved between 0-+ 0.25 D. Two-step surgery is recommended. It′s also recommended to make sure the lens is centered during the operation by lens reflection method.
ABSTRACT
Objective:To study the mechanism of Shengmaisan in treating atrial fibrillation by regulating relative genes and signaling pathways based on network pharmacology. Method:Target genes of Shengmaisan were obtained using Bioinformatics Analysis Tool for Molecular Mechanism of TCM（BATMAN-TCM） database，and target genes of atrial fibrillation were obtained through GeneCards，OMIM and DisGeNET databases. The target genes of Shengmaisan-atrial fibrillation intersection protein were obtained through the integration of the two groups of genes. STRING was used to build the protein-protein interaction network and visualize the results. The drug-disease intersection genes were introduced into the DAVID 6.8 database for gene ontology （GO） analysis and enrichment analysis based on the Kyoto Encyclopedia of Genes and Geomes （KEGG）. Result:A total of 159 active ingredients for Shengmai powder for atrial fibrillation were obtained. After the drug targets and the disease targets were intersected，206 common targets were obtained. PPI protein interaction network analysis showed that AKT1，TP53，PRKACA，IL-1B，TNF，INS，PPAR，RXR，F2，CACAN1C PKC might be the core targets of Shengmaisan in treating AF. GO enrichment analysis was used to identify 175 items （P<0.05），among which biological processes mainly included regulation of heart rate by cardiac conduction，membrane depolarization during action potential；cell components mainly included voltage-gated sodium/ potassium/calcium channel complex；molecular functions mainly included high-voltage-gated calcium channel activity，steroid hormone receptor activity. Through KEGG pathway enrichment analysis，100 signaling pathways were identified，mainly including cGMP/PKG signaling pathway，cAMP signaling pathway，serotonergic synapse，renin secretion，calcium signaling pathway. Conclusion:Based on the network pharmacology，Shengmaisan has multiple mechanisms in the prevention and treatment of atrial fibrillation. This study explores relevant signaling pathways，advantages and research directions of Shengmaisan in treatment of atrial fibrillation，so as to lay the foundation for further experimental verification.
ABSTRACT
Objective To investigate the effects of inhibitor of growth 5 (ING5) gene on the proliferation, apoptosis, migration and cell cycle of human breast cancer Bcap-37 cells.Methods The eukaryotic ING5-expressing plasmid and GFP-empty plasmid were steadily transfected in Bcap-37 cells, the expression of green fluorescent protein was measured with fluorescence microscopy, and the high expression of ING5 was measured by real time-PCR. Bcap-37-ING5 cells served as the experimental group, Bcap-37-GFP cells as the mock group and Bcap-37 as the control group. The effects of ING5 on the proliferation were detected by MTT, the cell cycle and apoptosis were detected by Flow cytometry, and the cell migration was detected by cell wound scratch assay and Transwell experiment.Results Bcap-37 cell lines steadily expressing ING5 protein with GFP-tag were acquired by stable transfection. ING5 over-expression inhibited the proliferation and led to G2 arrest of Bcap-37 cells, increased cells apoptosis and decreased the cell migration ability (P<0.05).Conclusion ING5 over-expression may have reverse effect for malignant phenotype of breast cancer cells, and may be employed to indicate the biomarker of prognosis of breast cancer patients and regarded as a target of gene therapy.
ABSTRACT
Objective To investigate the clinicopathological and prognostic significance of lysosome-associated membrane protein-2a (LAMP2a) expression in the development of colorectal cancer.Methods Immunohistochemistry was performed to detect the LAMP2a expression in colorectal cancer,normal mucosa,and adenoma tissues.Results LAMP2a expression in colorectal cancer and adenoma was higher than that in normal mucosa (P ＜ 0.05).Further,LAMP2a expression in colorectal cancer was negatively correlated with TNM staging and lymph node metastasis (P ＜ 0.05);however,the invasion and liver metastasis,depth of invasion and differentiation had no correlation with the lymph node (P ＞ 0.05).Kaplan-Meier analysis showed that LAMP2a expression in colorectal cancer is not significantly correlated with good prognosis (P ＞ 0.05).Univariate survival analysis showed that lymphatic invasion,vascular invasion,lymph node metastasis,TNM stage,liver metastasis,distant metastasis,and differentiation were correlated with poor prognosis of colorectal cancer (P ＜ 0.05).The Cox proportional hazards regression model showed that the depth of invasion and distant metastasis were important factors affecting the survival period of patients with colorectal cancer (P ＜ 0.05).Conclusion LAMP2a may play a role in the carcinogenesis and progression of colorectal cancer,and may be used as a molecular marker for the biological behavior of colorectal cancer.
ABSTRACT
Mitochondrial dysfunction plays an important role in the progress of heart failure [HF]. A pronounced variability of defects in mitochondrial subpopulations is reported to occur in various disease models. The aim of the study was to define the defects in the ultra structure and bioenergetic function of cardiac mitochondria in acute myocardial infarction-induced HF. AMI-induced HF rats were treated with saline [4.0ml/kg] for 8 weeks. The ultra structure of myocardial mitochondrial subpopulations was assessed by electron microscope. The bioenergetic function of myocardial mitochondrial subpopulations was evaluated through Clark oxygen electrode. Results indicated that myocardial mitochondrial subpopulations in Model group had abnormal mitochondrial morphology which manifested as swelling and vacuoles, membrane lysis, fuzzy ridge structure, cristae lysis or disappear in IFM particularly, while SSM was almost survived in AMI induced heart failure. Results showed that the oxidative phosphorylation function of respiratory chain of NADH oxidation was impaired notably. Compared with Sham group, both P/O [P<0.01] and OPR [P<0.01] of myocardial IFM in model rats decreased, and V3 [P<0.01], P/O [P<0.05] and OPR [P<0.01] of SSM in Model group decreased either. Meanwhile, the oxidative phosphorylation function of respiratory chain of FADH oxidation was injured in SSM particularly, which presented as the decreased P/O [P<0.01]. We propose that the mitochondrial defect of severe HF mostly lies in the interfibrillar mitochondria rather than in the subsarcolemmal mitochondria

Objective To investigate the clinical significance and abnormal expression of the CREB in different grade gliomas. Methods The expression of CREB was examined by using immunohistochemistry in brain tissues from the brain injury (5 cases) and different grade gliomas (55 cases).The mRNA and protein levels of CREB were further as?sessed using Western blot and RT-PCR in brain tissues from the patients with brain injury (10 cases) and those with dif?ferent grade gliomas (30 cases). Results The positive rates of CREB immunohistochemistry were 2/5 in control, 10/15 inⅠ-,Ⅱ11/12 in Ⅲ, 28/28 in Ⅳ. The positive rates of CREB were significantly different among different groups (H=28.183,P<0.05).The mRNA levels of CREB were 1.00 ± 0.000 in control, 1.35 ± 0.068 inⅠ-Ⅱ, 2.88 ± 0.111 in Ⅲand 3.75 ± 0.196 in Ⅳ. The expression of CREB was higher in the glioma than in control group, and the mRNA levels of CREB were significantly different among different groups(F=1.208,P<0.05). The protein levels of CREB were 0.311 ± 0.014 in control, 0.469±0.026 inⅠ-Ⅱ, 0.641±0.028 inⅢand 0.896±0.024 inⅣ. The protein levels of CREB were sig?nificantly different among different groups(F=1.123,P<0.05). Conclusion The expression of CREB is elevated in glio?mas with different differentiation degrees. The expression of CREB was positively correlated with the degree of differentia?tion, indicating that CREB may have an important regulatory role in the progress of gliomas.
ABSTRACT
Objective to explore the role of Beclin 1 in gastric carcinogenesis and subsequent progression. Methods MkN28 cells were trans-fected with Beclin 1-expressing plasmid,and then the proliferation and cell cycle was measured by CCk-8 and PI staining. Beclin 1 expression was examined by immunohistochemistry and in situ hybridization on tissue microarrays containing gastric cancers,adjacent non-neoplastic mucosa,and metastatic lymph node. the correlation with the tumorgenesis,clinicopathological and prognostic parameters was analyzed. Results Beclin 1 overex-pression resulted in G2 arrest of MkN28 cells and reduced the proliferation. Beclin 1 mRNA was highly expressed in gastric cancer than matched mu-cosa by ISH(P < 0.05). Beclin 1 was highly expressed in male than female patients with gastric cancer(P < 0.05). the elder patients with gastric cancer had higher Beclin 1 expression than younger ones(P < 0.05). the diffuse-type carcinomas showed less Beclin 1 expression than intestinal and mixed type ones(P < 0.05). kaplan-Meier analysis indicated that Beclin 1 expression was positively correlated to favorable prognosis of the can-cer patients(P < 0.05). Conclusion Beclin 1 expression is closely linked to pathogenesis,metastasis and differentiation of gastric cancer. Beclin 1 might be employed to indicate the favorable prognosis of gastric cancer patients and regarded as a target of gene therapy.
