Abstract:
ObjectiveTo investigate the possible mechanism of docosahexaenoic acid(DHA) regulating collagen expression by affecting the P38 MAPK pathway to play an anti-atrial fibrillation. MethodsEighty SD rats sensitive to acetylcholine(66 μg/mL)-calcium chloride(50 mg/mL) mixture were randomly divided into the control group(CON group), control DHA treatment group(DHA group), atrial fibrillation group(AF group) and atrial fibrillation DHA treatment group(DHA+AF group)(20 rats in each group model of atrial fibrillation).The BL-420F tractive electrocardiogram and continuous double stimulation method were used to detect the atrial effective refractory period(ERP), the whole cell patch clamp technique was used to record the atrial muscle cell action potential duration(APD) change, the enzyme immunosorbent assay(ELISA) was used to detect the typeⅠ, Ⅲ collagen expression in atrial muscle tissue of rats, and the expression levels of P38 and P-PP38 and MKP 1 protein were detected using Western blotting. ResultsThe duration of atrial fibrillation in rats prolonged with the increasing of experimental time, while DHA could shorten the duration of atrial fibrillation(P < 0.05 to P < 0.01).The ERP and APD significantly shortened, while DHA could significantly prolong the atrial ERP and APD in AF group(P < 0.01).There was no significant change in P38 protein among each group.Compared with the CON group, the expression level of P-P38 significantly increased, while the expression level of MKP-1 decreased in AF group(P < 0.01). Compared with the AF group, the expression level of P-P38 significantly decreased, while the expression level of MKP-1 increased in the DHA+AF group(P < 0.01).The results of ELISA showed that DHA could obviously down-regulate the typeⅠand Ⅲ collagen expression(P < 0.01). ConclusionsDHA may play an anti-atrial fibrillation role by regulating P38 MAPK signal transduction pathway mediating collagen expression.

Abstract:
ObjectiveTo investigate the effects of nerve growth factor(NGF) on the proliferation and differentiation of rabbit dental pulp stem cells(DPSCs) in vitro, and provide a new clue for the repair of dental pulp tissue. MethodsThe DPSCs from healthy New Zealand rabbits were isolated and cultured by tissue enzymedigestion method, and the morphology and growth changes of cells were observed under light microscope.The third passage DPSCs were divided into the blank group(only DPSCs), experimental group(DPSCs mixed with 100 g/L NGF) and control group(DPSCs mixed with mineralization solution).The cell morphology and alkaline phosphatase(ALP) activity in three groups were investigated after 7 days and 14 days of culture, and the mRNA expression levels of COL-1, Runx-2 and OCN were detected using RT-qPCR. ResultsThe DPSCs cultured in vitro grew well, adhered to the wall, and most of them were polygonal or spindle shaped with nest or colony growth.The ALP activity value in three groups after 14 d of culture were higher than that on the 7th day of culture, and the differences of which among three groups after 7 and 14 d of culture were significant(P < 0.05).The results of RT-qPCR showed that the expression levels of COL-1, Runx-2 and OCN mRNA in experimental group after 14 d of culture were higher than those in blank group(P < 0.05). ConclusionsThe NGF can promote the proliferation and osteogenic differentiation of rabbit DPSCs, and the combined application effect of the two is better than that of DPSCs alone.

Abstract:
ObjectiveTo analyze the protective effects of propofol on the acute lung injury induced by lipopolysaccharide(LPS)and expression levels of thioredoxin-interacting protein(TXNIP)and nucleotide-binding domain-like receptor protein 3(NLRP3), and explore the possible mechanisms of lung protection with propofol. MethodsForty ICR mice were divided into the control group(treatment with intraperitoneal injection of pH 7.4 phosphate buffer), LPS group(treatment with intraperitoneal injection of 30 mg/kg LPS), propofol group(treatment with intravenous injection of 40 mg/kg propofol)and propofol +LPS group(treatment with intraperitoneal injection of 30 mg/kg LPS after 20 min of intravenous injection of 40 mg/kg propofol)(10 mice in each group).The pathological analysis of lung tissue was conducted under light microscope, and the MDA content, SOD activity and expression levels of TXNIP and NLRP3 in pulmonary epithelial cells were detected. ResultsThe lung histopathological results showed that propofol could significantly reduced the acute lung injury induced by LPS in mice.Compared with the control group, the MDA content and SOD activity in the lung tissues of LPS group were significantly increased and decreased, respectively(P < 0.01), and the expression levels of TXNIP, NLRP3 mRNA and protein were significantly up-regulated in LPS group(P < 0.01).Compared with the LPS group, the MDA content and SOD activity were significantly decreased and increased in the propofol+LPS group, respectviely(P < 0.01), and the expression levels of TXNIP and NLRP3 mRNA and protein in lung tissues of propofol+LPS group were significantly down-regulated(P < 0.01). ConclusionsThe intravenous preinjection of propofol can down-regulate the mRNA and protein expressions of TXNIP and NLRP3 in lung tissues, effectively alleviate the acute lung injury induced by LPS, and play a protective role in lung tissue.

Abstract:
ObjectiveTo explore the diagnostic value of dual-energy spectral CT material quantitative analysis for pancreatic fat deposition. MethodsA total of 35 patients with metabolic syndrome, such as obesity, hyperglycemia and fatty liver, were selected as the observation group.The CT values of the head, body and tail of pancreas were measured on the single energy image of optimal keV value.The fat contents of the head, body and tail of pancreas were determined on the fat-water material image.The spectral curves of pancreatic tissues were obtained to make the average spectral curves.The results were compared with the fat contents measured in 30 patients who underwent abdominal CT scan for physical examination or other diseases in the control group. ResultsAmong 35 cases in the observation group, 8 cases were found with normal body mass index, and the rest were overweight or obesity.The average CT value of pancreas decreased with the increase of body mass index (P < 0.01), while the average fat content increased with the increase of body mass index(P < 0.01).The energy CT value and water content of pancreatic tissues in observation group were significantly lower than those in control group, and the fat content was significantly higher than that in control group(P < 0.01). ConclusionsDual-energy spectral CT quantitative analysis can objectively and quantitatively describe the fat deposition in pancreas, and provide more valuable informations for early diagnosis and treatment in clinic.

Abstract:
ObjectiveTo study the value of spectral CT texture analysis in predicting preoperative lymph node metastasis in patients with gastric cancer. MethodsEighty patients(including 57 cases in training group and 23 cases in verification group) with gastric cancer confirmed by surgical resection and pathology were retrospectively analyzed.The special texture analysis software AK was used to segment the lesions and extract the imaging features on the preoperative spectral CT 70 keV venous phase cross-sectional images.The Mann-Whitney U test was used to analyze the features between two groups, and the P < 0.05 features were preserved.The discriminative features were further found by single factor logistic regression analysis.The minimum redundancy maximum correlation method(MRMR) was used to eliminate the 10 features with the highest correlation with the label.Stepwise multiple logistic regression was used to construct the prediction model and final model.The performance of the model was evaluated using ROC analysis. ResultsIn terms of texture features, the 10 radiology-related features selected by MRMR had better discriminative ability for training group and verification group(AUC>0.64), and the AUC of multivariate logistic regression prediction model was 0.79(0.69-0.89). ConclusionsThe texture analysis based on spectral CT is expected to be a non-invasive tool for predicting preoperative lymph node metastasis in patients with gastric cancer.

Abstract:
ObjectiveTo explore the application value of spectral CT imaging in the qualitative evaluation of metastatic lymph nodes of differently differentiated esophageal cancer. MethodsThe clinical data of 48 patients with esophageal squamous cell carcinoma confirmed by endoscopic pathology were retrospectively analyzed.All cases were detected using spectral CT chest plain scan and dual-phase enhanced scan before surgery.The short diameter of mediastinal lymph nodes, CT value at 70 keV arterial and iodine concentration in arterial and venous phases were measured, the normalized iodine concentration was calculated, and which was compared with the postoperative pathological results. ResultsAmong the 48 patients with esophageal squamous cell carcinoma, 32 cases with lymph node metastasis and 16 cases without lymph node metastasis were confirmed by operation and pathology.The postoperative pathological results showed that 79 metastatic lymph nodes were found(including 14 highly differentiated squamous cell carcinoma metastatic lymph nodes, 27 moderately differentiated squamous cell carcinoma metastatic lymph nodes and 38 poorly differentiated squamous cell carcinoma metastatic lymph nodes), and there were 32 non-metastatic lymph nodes.There was no statistical significance in the diagnosis of lymph node metastasis between spectral CT imaging and pathological results after surgery(P>0.05).The short diameter, CT70 keV and arterial phase hormalized iodine concentration in highly and moderately differentiated esophageal squamous cell carcinoma metastatic lymph nodes were higher than those in non-metastatic lymph nodes(P < 0.05 to P < 0.01).The short diameter, CT70 keV and arterial phase hormalized iodine concentration in pooryly differentiated esophageal squamous cell carcinoma metastatic lymph nodes were higher than those in non-metastatic lymph nodes(P < 0.05 to P < 0.01).The ROC curve analysis showed that the sensitivity and specificity of the combined of CT70 keV, normalized iodine concentration and spectral curve slope in arterial phase in the diagnosis of metastatic lymph node of esophageal cancer were 86.1% and 87.5%, respectively. ConclusionsThe spectral CT imaging has important value in qualitative valuating the lymph nodes of differently differentiated esophageal cancer.It is helpful for N staging, clinical diagnosis and choice of treatment option of esophageal cancer.

Abstract:
ObjectiveTo investigate the value of anti-Miillerian hormone(AMH) combined with follicle stimulating hormone(FSH) in the evaluation of ovarian reserve function in elderly women scheduled by assisted reproductive technology. MethodsThe clinical data of 139 elderly patients(aged >35 years old) scheduled by assisted reproductive technology were retrospectively analyzed.According to the 2017 Poseidon poor ovarian response grouping criteria and ovarian reserve function test results, the patients were divided into normal group(n=51), diminished ovarian reserve(DOR) group(n=46) and premature ovarian failure(POF) group(n=42).According to the success of pregnancy within 1 year, the normal group was subdivided into the pregnant group(n=37) and non-pregnant group(n=14).The ovarian function-related assessment indexes were compared among all groups.The receiver operating characteristic curve(ROC) was used to evaluate the value of age, AMH and FSH alone or combined in the diagnosis of ovarian reserve dysfunction. ResultsThe age, FSH and LH in DOR and POF groups were significantly higher than those in normal group, while the AMH, AFC and E2 were significantly lower than those in normal group(P < 0.01).The age, FSH and LH in POF group were higher than those in DOR group, and the AMH, AFC and E2 in POF group were lower than those in DOR group(P < 0.05 to P < 0.01).The differences of the levels of PRL and P among three groups were not statistically significant(P>0.05).The results of correlation analysis showed that the AMH was positively correlated with AFC and E2(P < 0.01), and negatively correlated with the age, FSH and LH(P < 0.01).The FSH was positively correlated with age and LH(P < 0.01 and P < 0.05), and negatively correlated with AFC and E2(P < 0.01).There was not significant correlation among AMH, FSH, PRL and P(P>0.05).The critical values of age, AMH and FSH in the diagnosis of ovarian reserve dysfunction were 36.25 years old, 1.27 ng/mL and 8.11 U/L, respectively.The AUC value, sensitivity, specificity, PPV and NPV of three combination detection in the diagnosis of ovarian reserve dysfunction were 0.932, 93.18%, 94.11%, 96.47%, 88.89% and 96.59%, respectively, which were higher than those of single detection(P < 0.05).The levels of AMH and E2 in pregnant group were significantly higher than those in non-pregnant group(P < 0.01 and P < 0.05), while the levels of FSH and LH in pregnant group were significantly lower than those in non-pregnant group(P < 0.01). ConclusionsThe AMH and FSH are the effective indexes to evaluate the ovarian reserve function in elderly patients scheduled by assisted reproductive technology.The AMH combined with FSH detection technology can effectively replace the traditional evaluation system of ovarian reserve function.

Abstract:
ObjectiveTo analyze the incidence and risk factors of screw perforating humeru after internal fixation in patients with proximal humerus fractures. MethodsThe clinical data of 125 patients treated with open reduction-internal fixation with locking plates were analyzed.The patients were divided into two groups according to whether screw perforation.Among 125 cases, 18 patients with screw perforation and 107 patients without screw perforation were found.The risk factors of screw perforation in patients with proximal humerus fractures after internal fixation were analyzed. ResultsThe incidence rate of screw perforation in patients with proximal humeral fractures after internal fixation was 14.4%(18/125).The results of univariate analysis showed that the probability of screw perforation in patients with proximal humerus fractures complicated with medial column crushing, higher Neer type, medial column support, fewer screws and poor reduction after internal fixation were higher(P < 0.05 to P < 0.01).The results of multivariate logistic regression analysis showed that the Neer type, medial column crushing and poor reduction were the independent influencing factors of screw perforation after internal fixation in patients with proximal humeral fractures(P < 0.01). ConclusionsThe probability of screw perforation in patients with proximal humerus fractures complicated with medial column crushing, high Neer type and poor reduction is high.Clinically, some measures should be taken to strengthen the fracture stability and increase the humeral head support, so as to reduce the risk of screw perforation and improve the treatment effect of patients.
