ABSTRACT

Two prenylated 2-arylbenzofurans were isolated from roots of Artocarpus heterophyllus, with a combination of various chromatographic approaches, including ODS, MCI, Sephadex LH-20, and semipreparative high performance liquid chromatography(HPLC). They were identified as 5-[6-hydroxy-4-methoxy-5,7-bis(3-methylbut-2-enyl)benzofuran-2-yl]-1,3-benzenediol(1) and 5-[2H,9H-2,2,9,9-tetramethyl-furo[2,3-f]pyrano[2,3-h][1]benzopyran-6-yl]-1,3-benzenediol(2) with spectroscopic methods, such as HR-ESI-MS, IR, 1D NMR, and 2D NMR, and named artoheterins B(1) and C(2), respectively. The anti-respiratory burst activities of the two compounds were evaluated with rat polymorphonuclear neutrophils(PMNs) stimulated by phorbol 12-myristate 13-acetate(PMA). The results showed that 1 and 2 exhibited significant inhibitory effect on respiratory burst of PMNs with IC_(50) values of 0.27 and 1.53 μmol·L~(-1), respectively.

ABSTRACT

Objective:To analyze the correlation between chronic obstructive pulmonary disease (COPD) and cognitive dysfunction.Methods:This is a case-control study. From February 2022 to October 2022, 32 COPD patients (inpatient and outpatient) from the Department of Respiratory and Critical Care Medicine and Rehabilitation Medical Center of the First Affiliated Hospital of Nanjing Medical University and 32 healthy subjects were recruited. All participants underwent a thorough evaluation, which included Montreal Assessment of Cognitive Function (MoCA), visuospatial n-back task included accuracy (ACC) and mean response time (RT), the pulmonary functions including forced vital capacity (FVC), forced expiratory volume in the first second (FEV 1), one-second rate (FEV 1/FVC) and maximum volume per minute (MVV), Health Survey Short Form (SF-36), and St. George′s Respiratory Questionnaire (SGRQ). The correlation between cognitive dysfunction and lung function, SF-36 and SGRQ in COPD patients were analyzed. Results:The prevalence of smoking, hypertension and cardiovascular disease in the two groups were significantly different (all P<0.05). MoCA score, 1-back ACC and 2-back ACC in COPD group were significantly lower than those in healthy control group [(23.86±4.50) vs (27.55±1.29) points, (76.82%±16.60%) vs (90.61%±7.40%), (67.93%±10.10%) vs (78.74%±10.38%), all P<0.001]; 2-back RT was significantly higher than that of healthy group [(316.43±108.17) vs (254.09±101.62) ms, P<0.05]; and the Physiological function (PF), physiological function (RP), emotional function (RE), energy (VT), social function (SF), physical pain (BP) in SF-36 were significantly worse than the healthy control group (all P<0.05). The MoCA score of COPD group was positively correlated with FEV 1/FVC ( r=0.501, P=0.018). The 1-back ACC was positively correlated with FEV 1 and FEV 1/FVC ( r=0.568, 0.634; both P<0.05). The 1-back RT was negatively correlated with FEV 1/FVC and MVV ( r=-0.452, -0.534; both P<0.05). The 2-back ACC was positively correlated with FEV 1/FVC ( r=0.426, P=0.048). The 2-back RT was negatively correlated with MVV ( r=-0.571, P=0.006). In COPD group, MoCA score was negatively correlated with activity, influence and total score in SGRQ ( r=-0.533, -0.466, -0.521; all P<0.05). The 1-back ACC was negatively correlated with activity, influence and total score ( r=-0.552, -0.517, -0.584; all P<0.05). The 1-back RT was positively correlated with activity, influence and total score ( r=0.430, 0.379, 0.417; all P<0.05). The 2-back ACC was negatively correlated with impact and total score ( r=-0.398, -0.412; both P<0.05). Conclusion:COPD patients have impaired cognitive function, which is mainly manifested by the decline of working memory and executive function, and is correlated with the lung function, general health condition and quality of life.

ABSTRACT

ObjectiveTo understand the physical development level of 3-7 years old children in Zhag′yab, and to provide reference for local health decision-making. MethodsA cross-sectional study was conducted between June 2021 and July 2021, with a sample of 1 247 Tibetan children aged 3-7 years from kindergartens in 13 districts of Zhag′yab. Their height and weight were measured and the hemoglobin was detected by a unified method. Standard statistical method was adopted (Z-score method). Z-scores of length /height-for-age (HAZ), Z-scores of weight-for-age (WAZ), Z-scores of body mass index (BMI)-for-age (BAZ) and Z-scores of weight-for-height (WHZ) were calculated by WHO Anthro v3.2.2 and WHO Anthro Plus. The nutritional status of children was evaluated according to WHO diagnostic criteria for malnutrition and anemia. ResultsThe average WAZ and HAZ of children aged 3 to 7 in Zhag′yab were lower than the WHO standards,except for the WAZ of 4-year old, the differences were statistically significant (P<0.05). The overall detection rate of malnutrition was 25.7%, stunting, underweight, wasting, overweight, obesity and anemia were 11.6%, 11.8%, 10.8%, 3.3%, 1.8% and 29.3%, respectively. The detection rates of all indicators in boys were higher than those in girls, and the differences were not statistically significant (P>0.05). The overweight rate and obesity rate of rural children were lower than those of urban children, and the other detection rates were higher than those of urban children. The differences of underweight rate, obesity rate and anemia rate were statistically significant between urban and rural children (P<0.05). Among the detection rates of all indicators in different age groups, there were statistically significant differences in the overweight rate and the anemia rate (P<0.05). The overweight rate of children aged 4 and the anemia rate of children aged 5 were the highest. ConclusionsThe physical development of children aged 3 to 7 in Zhag′yab is poor, and the prevalence of malnutrition and anemia is high. Underweight and anemia are more serious in rural children, and the overweight and obesity problem of urban children is emerging. More attention should be paid to promote their nutritional status. The prevention and intervention of children’s malnutrition should be strengthened in Zhag′yab.

ABSTRACT

{L-End}Objective To analyze the effects of night shift work and overweight/obesity on blood pressure of workers in chemical fiber industry. {L-End}Methods A total of 1 004 workers of a chemical fiber factory were selected as the study subjects using convenient sampling method, and their blood pressure and body mass index were measured. Multiple linear regression model was used to analyze the relationship between night shift work and blood pressure, and multiple logistic regression was used to assess the independent impact and combined impact of night shifts and overweight/obesity on the risk of hypertension. {L-End}Results Compared with the non-night shift workers, the prevalence of hypertension in night shift workers was increased (5.3% vs 13.0%, P<0.05), with elevated systolic and diastolic blood pressure (both P<0.05). The results of multiple linear regression analysis showed that the systolic blood pressure and diastolic blood pressure of the night shift workers were higher than those of the non-night shift workers (both P<0.05), and the systolic blood pressure and diastolic blood pressure of overweight/obesity workers were higher than those of non-overweight/obesity workers (both P<0.01). The results of multiple logistic regression analysis showed that the risk of hypertension in night shift workers and overweight/obesity workers was higher than that in non-night shift workers and non-overweight/obesity workers [odds ratio (OR) and 95% confidence interval (CI) were 2.49 (1.04-5.99) and 2.65 (1.77-3.95), both P<0.05]. Night shift work and overweight/obesity showed a synergistic effect on blood pressure of workers. Compared to non-overweight/obesity non-night shift workers, overweight/obesity night shift workers had a higher risk of hypertension (OR=4.93, 95%CI: 1.70-14.29, P<0.01). {L-End}Conclusion Night shift work could lead to elevated blood pressure in workers in the chemical fiber industry, which is a potential risk factor for hypertension. The synergistic effect of night shift work and overweight/obesity may contribute to the increased risk of hypertension.

ABSTRACT

Objective:To investigate the medium- and long-term efficacy of peroral endoscopic myotomy (POEM) for esophageal diverticulum and the risk factors for postoperative recurrence.Methods:A retrospective study was conducted on 31 cases of esophageal diverticulum who were treated by POEM in Zhongda Hospital, Southeast University from May 1st 2016 to August 1st 2019. The Eckardt score, the operative success rate, and the recurrence rate after the operation were observed and recorded. Multivariate logistic regression analysis was performed to explore the risk factors for postoperative recurrence.Results:POEM was successfully completed in all 31 patients, who were followed up for 30.6±11.1 months (20-63 months). The Eckardt score before the operation was 8.2±2.4, and was 1.4±0.7, 1.4±1.1, 1.3±1.1, and 1.3±0.9 at 1, 6, 12 and 24 months, respectively after the operation, which significantly decreased at all follow-up time points ( P<0.001). The success rates at 1, 6, 12, and 24 months after the operation were 96.8% (30/31), 90.3% (28/31), 90.3% (28/31) and 90.3% (28/31), respectively. Three patients suffered symptom relapse, with an overall recurrence rate of 9.7% (3/31). Logistic regression analysis showed that the disease duration ( P=0.038, OR=1.041, 95% CI: 1.002-1.080) and preoperative Eckardt score ( P=0.024, OR=2.299, 95% CI: 1.117-4.728) were risk factors for postoperative recurrence of POEM. Conclusion:POEM is safe and effective for esophageal diverticulum. Patients with long disease duration and high preoperative Eckardt score are associated with recurrence.

ABSTRACT

Objective:To conduct a glucagon like peptide-1(GLP-1)controllability model rat by chemical genetics, and observe the impact of GLP-1 neuron excitability on appetite.Methods:Fifteen rats were evenly divided into Green fluorescent protein(GFP)group, HM3D group, and HM4D group. Various combinations of adeno-associated virus(rAAV)were injected into the nucleus tractus solitarius(NTS). rAAV-GLP-1-cre and rAAV-GFP-dio were administered in rats of GFP group. The rats of HM3D group were injected with rAAV-GLP-1-cre and rAAV-HM3D-mCherry-dio while rAAV-GLP-1-cre and rAAV-HM4D-mCherry-dio were injected in rats of HM4D group . The optimal dose of clozapine N-oxide(CNO)was selected based on feeding behavior and body weight changes of rats after intraperitoneal injection of different doses of CNO. The controllability of GLP-1 neurons was confirmed by comparing with intraperitoneal injection of saline. The number of activated GLP-1 neurons in the NTS area and the expression of POMC neurons in the hypothalamus were detected 30 minutes after CNO injection.Results:GLP-1 neurons in the NTS area of rats were successfully labeled. The rat of HM3D group revealed a decrease in food intake( P=0.021)while the rat of HM4D group showed an increase( P=0.002), when given 1 mg/kg of CNO, no changes at the dose of 0.5 mg/kg and 3.0 mg/kg. Immunofluorescence showed that the activity of GLP-1 neurons in NTS of GFP group was lower than that of HM3D group( P=0.022), and higher compared with that of the HM4D group( P=0.049). The expression of GLP-1 neurons in NTS and POMC neurons in the hypothalamus of the HM3D group after intraperitoneal injection of CNO was also higher than that in the HM4D group( P=0.003). Conclusion:Using chemical genetics technology, GLP-1 controllability model rat could be successfully established via injecting varying combinations of rAAV into the NTS area of rat. Injection of 1 mg/kg CNO can effectively activate or inhibit the neuron to regulate appetite.

ABSTRACT

Objective:To compare the chemical constituents of Puerariae Flos from three different varieties of <italic>Pueraria montana</italic> var. <italic>lobata</italic>, <italic>P. montana</italic> var. <italic>thomsonii</italic> and <italic>P</italic>. <italic>montana</italic> var<italic>. montana</italic>. Method:Ultra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry (UPLC-Q-TOF-MS) was used with the mobile phase of 0.1% formic acid aqueous solution (A)-acetonitrile (B) for gradient elution (0-20 min, 10%-30%B; 20-30 min, 30%-55%B; 30-35 min, 55%-95%B; 35-37 min, 95%B; 37-40 min, 95%-10%B), the flow rate was 0.25 mL·min<sup>-1</sup>. Electrospray ionization (ESI) was used to scan and collect MS data in positive and negative ion modes with scanning range of <italic>m</italic>/<italic>z</italic> 50-1 500. The chemical components from different sources of Puerariae Flos were identified in combination with the chemical composition database and literature information. After the obtained data were normalized by MarkerView<sup>TM</sup> 1.2.1, they were imported into SICMA-P 14.1 software for principal component analysis (PCA) and orthogonal partial least squares discriminant analysis (OPLS-DA) to select the main differentiated components among the three different varieties. Result:A total of 35 compounds were identified from three different varieties of Puerariae Flos, including 22 isoflavones, 6 flavonoids and 7 saponins. The flowers of <italic>P</italic>. <italic>lobata</italic>, <italic>P. montana</italic> var. <italic>thomsonii</italic> and <italic>P</italic>. <italic>montana</italic> var<italic>. montana</italic> contained 32, 35, 33 compounds, respectively. And 18 differential compounds were screened under the positive and negative ion modes, including kakkalide, tectoridin, 6″-<italic>O</italic>-xylosyl-tectoridin, 4'-methyltectorigenin-7-glucoside, glycitin, 6″-<italic>O</italic>-xylosyl-glycitin, irisolidone, kaikasaponin Ⅲ, 6″-<italic>O</italic>-malonylglycitin, kakkalidone, tectorigenin, rutin, soyasaponin BB, vitexin, biochanin A, genistin, kakkatin, azukisaponin Ⅱ. Conclusion:This research is the first to systematically study the chemical constituents of the flower of <italic>P</italic>. <italic>montana</italic> var<italic>. montana</italic>, although the flower of <italic>P</italic>. <italic>montana</italic> var<italic>. montana</italic> is used as adulterants, it has high contents of tectoridin and 6″-<italic>O</italic>-xylosyl-tectoridin, which has great potential for development. The efficacy components such as kakkalide and tectoridin in Puerariae Flos from the three sources of varieties are obviously different, and it is necessary to carefully consider the application of these three varieties as Puerariae Flos.

ABSTRACT

Objective:To explore the feasibility, accuracy and reproducibility of a novel, fully automated three-dimensional echocardiography right ventricular(RV) quantification software(3D Anto RV) to evaluate the RV volume and RV ejection fraction (RVEF) using artificial intelligence in patients after heart transplantation (HT) comparing with the gold reference-cardiac magnetic resonance (CMR).Methods:Forty-six patients after HT who were scheduled for echocardiogram at their routine follow-up examinations and also agreed to undergo CMR examination within the following 24 hours in Union Hospital, Tongji Medical College, Huazhong University of Science and Technology from October 2018 to June 2019 were prospectively included. The right ventricular end-diastolic volume (RVEDV), right ventricular end-systolic volume (RVESV), right ventricular stroke volume (RVSV) and RVEF of HT patients were measured by CMR 3D Auto RV and conventional semi-automated three-dimensional echocardiography RV quantification software (Tomtec 4D RV function 2.0). The results of the 3D Auto RV and conventional semi-automated Tomtec were respectively compared with CMR using paired two-tailed student′s t-tests, Pearson correlation coefficients and Bland-Altman analyses. Results:The feasibility of the 3D Auto RV was 87%.The fully automated analysis realized in 27 (59%) patients by 3D Auto RV and the analysis time required only (12±1)s. The results of the remaining 19 (41%) patients needed manual adjustment and the mean analysis time in manual adjustment was also <2 min that was shorter than the conventional semi-automated three-dimensional echocardiography RV quantification software[(108±15)s vs (160±34)s, P<0.001]. For the results of RV volumes: There were good correlations between the 3D Auto RV and CMR, conventional semi-automated Tomtec and CMR for the measurements of RVEDV, RVESV and RVSV ( r=0.77-0.84, all P<0.001). In addition, compared with CMR, although there were significantly underestimated RV volumes by the 3D Auto RV and conventional semi-automated Tomtec, the negative bias was smaller in the 3D Auto RV than the conventional semi-automated Tomtec. For the results of RVEF: the corresponding RVEF derived from 3D Auto RV and CMR showed an excellent correlation and consistency ( r=0.84, P<0.001; bias=-1.1%, Limit of agreement=-8.1%-6.0%). In addition, the correlations between the manual adjustment by 3D Auto RV and the CMR ( r=0.63-0.72, all P<0.001) was lower than the correlations between the 3D Auto RV and the CMR ( r=0.76-0.82, all P<0.001) for RV volumes and RVEF.Finally, 3D Auto RV had a good reproducibility. Conclusions:The new fully 3D Auto RV quantification software underestimate RV volumes that less than the conventional semi-automated Tomtec. And the 3D Auto RV quantification software can accurately evaluate the RVEF in patients after HT with rapid analysis and higher reproducibility, which may also support the routine adoption of this method during follow-ups of HT patients in the daily clinical workflow.

ABSTRACT

Objective@#To investigate the three-dimensional forces created by clear aligners on mandibular teeth during differential activation with en-masse retraction and/or intrusion in vitro. @*Methods@#Six sets of clear aligners were designed for differential en-masse retraction and/or intrusion procedures in a first premolar extraction model. Group A0 was a control group with no activation. Groups A1–5 underwent different degrees of retractions and/or intrusions. Each group consisted of 10 aligners. Aligner forces were measured on a multi-axis force/ torque transducer measurement system in real-time. @*Results@#In the en-masse retraction groups (A1 and A2), lingual and extrusive forces were observed on the incisors; the canines mainly received distal forces; intrusive forces were seen on the second premolars; and the molars received mesial forces. In the enmasse retraction and intrusion groups (A3, A4, and A5), incisors also received lingual and extrusive forces; canines received distal and intrusive forces; mesial and extrusive forces were seen on the second premolars; and the second molars received distal and intrusive forces. The vertical forces on the incisors did not differ significantly among groups A1, A3, and A5. However, the vertical forces on the second premolars reversed from intrusion in group A1 to extrusion in groups A3 and A5. @*Conclusions@#With clear aligners, the “bowing effect” is seen during en-masse anterior teeth retraction and can be partially relieved by performing en-masse retraction accompanied by anterior teeth intrusion.Vertical control of incisors remained unsolved during en-masse retraction, even when intrusive activation was added to the anterior teeth.

ABSTRACT

Objective:To study the components with urate anion transporter 1(URAT1) regulation effect and their combination mechanisms of Lagotis brevituba by integrating techniques of HK-2 cell capture,UPLC-Q-TOF-MS and molecular docking,so as to provide material and theory bases for the development of new hypouricemic medicines based on L. brevituba. Method:The HK-2 cells were applied to capture the components of L. brevituba. UPLC-Q-TOF-MS was used to identify those components. The molecular docking technique was adopted to study the interaction mechanism between the compounds and URAT1. Result:Eight components were successfully screened and identified as hyperoside,plantamajoside,kaempferol-3-O-glucoside,lugrandoside,nepitrin,isolugrandoside,homoplantaginin,luteolin,respectively. Those components could combine with URAT1 mainly through hydrogen bond,van der Waals force and hydrophobic action,which were closely related to structure and compound types. Furthermore,the LibDock score of phenylethanoids was higher than that of flavonoids. Conclusion:The integration of target cell capture,UPLC-Q-TOF-MS and molecular docking techniques could be successfully used to identify captured compounds of L. brevituba with URAT1 regulation effects and illustrate their potential combination mechanisms as well as the structure-activity relationships. The findings may provide material and theory bases for the development of new hypouricemic medicines based on L. brevituba.

ABSTRACT

Objective:To investigate the preliminary clinical and radiographic outcomes of percutaneous endoscopic lumbar discectomy (PELD) combined with oblique lateral interbody fusion (OLIF) for the degenerative lumbar spondylolisthesis, lumbar spine instability or lumbar spinal stenosis with ruptured disc herniation.Methods:Data of 11 patients with degenerative lumbar spondylolisthesis, lumbar spine instability or lumbar spinal stenosis with ruptured disc herniation who had undergone PELD combined with OLIF between March 2017 to July 2018 in our spine surgery center were retrospectively analyzed. There were 5 males and 6 females with an average age of 61.2±6.8 years old. All the patients were diagnosed with degenerative lumbar diseases including lumbar spondylolisthesis (7 cases), lumbar spinal stenosis (3 cases) and segmental instability (1 case). The patients were treated with PELD combined with OLIF. The visual analogue scale (VAS) scores of low back pain and lower limb pain and the Oswestry disability index (ODI) of lumbar function, spinal canal anteroposterior diameter, intervertebral disc height, vertical diameter of intervertebral foramen, segmental angle and the whole lumbar lordotic angle were collected.Results:All patients received PELD with local anesthesia before OLIF with general anesthesia. The mean operation time was 52.3±13.2 min and the mean blood loss was 10.9±4.7 ml for PELD. The mean operation time was 56.8±18.0 min and the mean blood loss was 65.5±24.6 ml for OLIF. All patients were followed up for an average of 11.2 months. At the latest follow-up, the mean VAS score for back pain was 1.3±0.8, the mean VAS score for leg pain 1.1±0.5, the mean ODI 14.6%±5.3%, thus all of those were improved significantly compared to those of pre-operation ( t=10.37, 16.49, 8.73; P< 0.05). The radiographic results showed the mean pre-operative intervertebral disc height, vertical diameter of intervertebral foramen, spinal canal anteroposterior diameter, segmental angle, and lumbar lordosis angle was 7.1±1.2 mm, 15.3±2.2 mm, 6.2±1.3 mm, 10.2°±3.5°, 16.2°±6.2°, and thus all of those were increased significantly to the latest follow-up 11.5±1.8 mm, 19.2±2.6 mm, 10.4±2.5 mm, 19.3°±7.8°, 27.4°±8.3°, respectively ( t=5.83, 4.21, 6.59, 10.32, 7.65; P< 0.05). One of the patients had weakness of flexor hip strength and one had a transient paresthesia immediately post-operation. All symptoms were relieved within 1 month. Another one case had cage subsidence and encountered serious back pain after 1 month, and alleviated after percutaneous pedicle screw fixation.

ABSTRACT

The theory and technique of s infantile Chinese massage of the western part of Hunan province are reviewed in clinical diagnosis and treatment and the core theoretical system is refined. Based on clinical experiences and in consideration of the analysis on relevant literature, the academic system of s infantile Chinese massage of the western part of Hunan province is summarized as four aspects, named "theory, method, recipe and degree". "Theory" refers to the four diagnostic methods and eight principle in terms of diagnosis and treatment and the therapeutic emphasis on the main disorders of organs in children. "Method" refers to promotion and restriction of five elements, meridian tropism in treatment. "Recipe" refers to the selection of acupoints, optimization of therapeutic techniques and the key in the composition of the herbs with different roles considered, named monarch herb, minister herb, assistant herb and guiding herb. "Degree" refers to the strength and intensity of manipulation to ensure the optimal effect. All of the aforementioned reviews provide the reference to theoretic study on this Chinese massage school.

ABSTRACT

Objective: To determine the optimal manipulation parameters in Liu's back tuina therapy for remission-stage cough variant asthma (CVA) in kids. Methods: A 5-factor 3-level L18(37) orthogonal design was adopted. The experimental factors and levels were selected: A, the number of times of Rou-kneading Feishu (BL 13); B, the frequency of Rou-kneading Feishu (BL 13); C, the number of times of Tui-pushing in a '介'-like pattern; D, the frequency of Tui-pushing in a '介'-like pattern; E, the intensity of red color after Ca-scrubbing Feishu (BL 13) with salt. A1, A2 and A3 stood for 10 times, 20 times and 30 times, respectively; B1, B2 and B3 stood for 200 times/min, 240 times/min and 280 times/min, respectively; C1, C2 and C3 stood for 50 times, 75 times and 100 times, respectively; D1, D2 and D3 stood for 150 times/min, 175 times/min and 200 times/min, respectively; E1, E2 and E3 stood for pinkish, bright red and dark red, respectively. A total of 108 kids with CVA in remission stage were divided into 18 groups using the random number table method, with 6 cases in each group. Changes in the cough score and fractional exhaled nitric oxide (FENO) level were observed after 15-day treatment. Results: The cough score and FENO level changed significantly in every group after treatment (all P<0.01). By the effect in improving cough score, the factors were listed as D, B, A, C and E in descending order; the most optimal manipulation parameter combination was group 17 (A3B2C1D3E1); the second optimal parameter combinations were group 7 (A3B1C2D1E3), group 13 (A2B1C2D3E1) and group 14 (A2B2C3D1E2). Regarding the effect in down-regulating the level of FENO, the factors were listed as C, A, E, B and D in descending order; the most optimal manipulation parameter combination was group 13 (A2B1C2D3E1); the second optimal parameter combinations were group 18 (A3B3C2D1E2), group 16 (A3B1C3D2E3) and group 14 (A2B2C3D1E2).Conclusion: Two most effective manipulation parameter combinations were selected out of 18 different parameter combinations in Liu's back tuina therapy for remission-stage CVA in kids. Doctors can choose an appropriate manipulation based on the symptom features of the disease.

ABSTRACT

The aim of the study is to identify the effects and underlying mechanisms of visfatin on inflammation and necroptosis in vascular endothelial cells. Human umbilical vein endothelial cells (HUVECs) were stimulated with visfatin or pretreated with Polyinosinic acid (LOX-1 inhibitor). By using the Western blot, RT-PCR, immunocytochemistry, enzyme-linked immunosorbent assay (ELISA), MTT and flow cytometry technique, the occurrence of inflammation and necroptosis in HUVECs were evaluated. Our results showed that 100 ng/mL visfatin significantly increased the mRNA and protein expression of monocyte chemotactic protein 1 (MCP-1) and LOX-1 after 24 hours' treatment in HUVECs. However, pretreatment with Polyinosinic acid could significantly reduce the expression of MCP-1 compared with visfatin group. Additionally, 100 ng/mL visfatin could induce the production of necrotic features and increase the mRNA expression of BMF (one of the markers of necroptosis), while pretreating with Polyinosinic acid markedly downregulated the mRNA expression of BMF gene and promoted the cell proliferation. These results indicate that visfatin might induce inflammation and necroptosis via LOX-1 in HUVECs, suggesting that visfatin plays a central role in the development of atherosclerosis.

ABSTRACT

Objective Hilar cholangiocarcinoma (HC) is invariably fatal without surgical resection. The primary aim of the current study was to determine the safety of variable surgical resections for patient with HC and their survival after surgical resection. In addition, prognostic factor for the overall survival was also evaluated. Methods The study included 59 consecutive patients who were newly diagnosed with HC and underwent surgical resections with curative intend between February 2009 and February 2017. Patients were followed up at 3-6 months intervals after hospital discharge. Postoperative complications and overall survival were determined. Associations of clinicopathologic and surgeon-related factors with overall survival were evaluated through univariate analysis and Cox regression analysis. Results Of patients with Bismuth and Corlette (B & C) type Ⅲ (=19) and Ⅳ (=25) HC lesions, 33 (55.9%) were treated with hilar resection combined with major liver resection (MLR), while the other 11 patients with type Ⅲ and Ⅳ, and those with type Ⅰ (=8) and Ⅱ (=7) HC lesions were treated with hilar resection. The overall surgical mortality was 5.1% and surgical morbidity was 35.6%. There was no statistical difference in the mortality between MLR group and hilar resection group (6.1% 3.8%; =0.703, =0.145). The median follow-up period was 18 months (range, 1-94 months). The 1-, 3-, 5-year survival rate was 59.3%, 36.5%, and 17.7%, respectively. The overall survival after resections was 18 months. In HC patients with B & C type Ⅲ and Ⅳ lesions, the median survival was 23 months for hilar resection with MLR and 8 months for hilar resection alone; the 1-, 3-, 5-year cumulative survival rate was 63.9%, 23.3%, and 15.5%, respectively for hilar resection with MLR, and 11.1%, 0, and 0, respectively for hilar resection alone, with significant differene observed (, 9.902; 95% , 2.636-19.571, =0.001). Four factors were independently associated with overall survival: preoperative serum Ca19-9 (, 7.039; 95% , 2.803-17.678, <0.001), histopathologic grade (, 4.964; 95% , 1.046-23.552, =0.044), surgical margins (=0.031), and AJCC staging (=0.015). Conclusions R0 resection is efficacious in surgical treatment of HC. MLR in combination with caudate lobe resection may increase the chance of R0 resection and improve survival of HC patients with B & C type Ⅲ and Ⅳ lesions. Preoperatively prepared for biliary drainage may ensure the safety of MLR in most HC patients. Novel adjuvant therapies are needed to improve the survival of HC patients with poor prognostic factors.

ABSTRACT

Objective: To investigate the protective effect of Perillae Folium with aqueous extract (PFAE) on some key factors of Adriamycin (ADR)-induced oxidative injury in human renal tubular epithelial cells(HK-2), including the survival rate, oxidative injury indexes and cell apoptosis,in order to define the underlying mechanism. Method: A model of ADR-induced HK-2 cells oxidative injury was established in vitro, then cell viability was detected by cell counting kit-8 (CCK-8) after intervention with positive reference N-acetylcysteine (NAC) or PFAE (5,15,45 g·L-1) at different concentrations. According to the morphological changes under microscopy, the optimum concentration of PFAE was screened out for the follow-up experiments. Then, the experiments were divided into six groups:blank group, ADR (0.05 g·L-1) group, PFAE (15 g·L-1) group, ADR+PFAE (0.05+15) g·L-1 group, NAC (0.81 g·L-1) group, and ADR+NAC (0.05+81) g·L-1 group. After that, malondialdehyde (MDA), superoxide dismutase (SOD), total antioxidant capacity(TAC) were measured in the cell homogenate after 24 h administration. The level of reactive oxygen species (ROS) was detected by 2',7'-dichloroflurescin diacetate (DCFH-DA) fluorescence probe. Flow cytometry and TdT-mediated dUTP Nick-End Labeling (TUNEL) were used to monitor the cell apoptosis. Western blot was used to observed the expressions of mitochondrial apoptosis-associated proteins, like B lymphocyte tumor-2 gene (Bcl-2), Bcl-2 related X protein (Bax), cysteine aspartate protease-9 (Caspase-9), cysteine aspartate protease-3 (Caspase-3) and poly ADP-ribose polymerase (PARP), as well as their shear bodies. In addition, the phosphorylation protein expressions of p38 mitogen-activated protein kinase (p38 MAPK), extracellular signal-regulated kinase (ERK), c-Jun amino-terminal kinase (JNK) in mitogen-activated protein kinase (MAPK) signaling transduction pathway were detected by Western blot. Result: Compared with blank group, ADR group showed a decreased cell viability (PPPPPPPP-1. The ATC and SOD levels were increased in ADR+PFAE group and ADR+NAC group (PPConclusion: PFAE could alleviate the oxidative injury of HK-2 cells induced by ADR, and have an antioxidant effect, which inhibited cell apoptosis through mitochondrial apoptotic pathway and ERK/p38 MAPK signaling pathway.
