Aim To determine the effect of FATP5 gene silencing on fatty hepatic cell inflammation and to explore its possible mechanism. Methods Five shR-NA sequences were designed and synthesized. The efficient FATP5-shRNA was screened by the siCHECK™ system. After preparing the FATP5-shRNA lentivirus, the FATP5 gene silence hepatic cell lines was obtained by HepG2 cell infection and puromycin screening. The FATP5 silencing efficiency was detected by Western blot. Then the oleic acid induced ROS and MDA generation, TNF-a and IL-6 protein expression and secretion, and NF-kB activation in FATP5 gene silence cells were analyzed by the detection kit, Western blot, nucleo-plasmic separation and reporter gene system. Results In the gene silence cells, FATP5 protein expression was reduced by 90% and the lipid accumulation was also significantly inhibited. Moreover, the FATP5 knockdown could reduce the oleic acid induced ROS and MDA generation, and suppress the NF-kB activation, thereby inhibiting the protein expression and secretion of TNF-a and IL-6. Conclusions FATP5 gene silence inhibits fatty hepatic cell inflammation, and its mechanism may be related to the inhibition of oxidative stress and lipid peroxidation.

The present study analyzed and identified the chemical constituents from ethyl acetate(EA) extract of Taxilli Herba with UPLC-Q-Exactive-MS and screened active xanthine oxidase(XO) inhibitors with HPLC. The analysis was performed on an Hypersil GOLD C_(18) reversed-phase column(2.1 mm×50 mm, 1.9 μm), with the mobile phase of water containing 1% formic acid(A) and methanol(B) under gradient elution, the flow rate of 0.3 mL·min~(-1), and the injection volume of 5 μL. ESI source was used for MS and the compounds were collected in positive and negative ion modes. Xcalibur 4.1 was used to analyze the retention time, accurate relative molecular weight, and fragmentation of the compounds. The inhibitory activity of some known compounds on XO was screened by HPLC. Thirty chemical constituents were identified, including phenolic acids and flavonoids by experimental data combined with information of standards, data reported previously, and databases, such as MzCloud and ChemSpider. The activities of 10 chemical components were screened. Gallic acid and naringenin chalcone had strong inhibitory activities on XO with IC_(50) of 57 μg·mL~(-1) and 108 μg·mL~(-1). UPLC-Q-Exactive-MS allows the accurate, rapid, and comprehensive identification of main chemical constituents from Taxilli Herba. Gallic acid and naringenin chalcone may be the active components of XO inhibitors.

To investigate the effect of patchouli alcohol on inhibiting Helicobater pylori urease activity, and its effect on expression levels of related genes, and lay the foundation for further research on the effect of patchouli alcohol on H. pylori colonization and infection. H. pyloriwas cultured and identified by gram staining, rapid urease test (RUT) and PCR method. Then agar dilution method was used to detect the bacterial survival after 1 h intervention by different concentrations of patchouli alcoholin the acidic (pH 5.3) and neutral (pH 7.0) conditions; berthelot method was used to detect urease activity and RT-qPCR method was used to detect the expression changes of ureA, ureB, ureE, ureH, ureI, and nixA related urease genes. The results showed that the survival rate of H. pyloriwas not significantly changed but the urease activity was obviously decreased after intervention by different concentrations of patchouli alcohol; meanwhile, the expression levels of ureA, ureB, ureE, ureH, ureI, and nixA were decreased to different degrees. Therefore, patchouli alcohol could inhibit H. pylori urease activity in both acidic and neutral conditions, and the mechanism may be related to down-regulation of urease gene expression.

OBJECTIVETo evaluate the prognosis effect of Chinese herbal medicines (CHMs) for benefiting qi and activating blood circulation adjunctive to conventional treatment in patients with acute coronary syndrome (ACS) after percutaneous coronary intervention (PCI).
METHODSA total of 702 patients with ACS who underwent PCI were enrolled and randomly assigned to receive conventional treatment plus CHMs for benefiting qi and activating blood circulation (treatment group, 351 cases) or conventional treatment alone (control group, 351 cases) for 6 months. Six months later, all patients received conventional treatment alone. Follow-ups were scheduled at 6th, 12th, 18th, 24th month after enrollment in April 2008, and the final follow-up visit was during September 2011 and November 2011. The primary endpoint was the composite of cardiac death, nonfatal myocardial infarction or revascularization (PCI or coronary artery bypass grafting); and the secondary endpoint was the composite of re-admission for ACS, congestive heart failure, nonfatal stroke or other thrombus events.
RESULTSA total of 621 (88.59%) patients completed 35.4±3.8 months follow-up, while 80 (11.41%) patients withdrew from the trial (41 in the treatment group and 39 in the control group). The incidence of primary endpoint was 5.7% (20 patients) in the treatment group versus 10.86% (38 patients) in the control group [relative risk (RR): 0.53; 95% confidence interval (CI): 0.30, 0.88; P=0.013; absolute risk reduction (ARR):-0.052, 95% CI: -0.06, 0.01]. The incidence of secondary endpoint was 5.98% (21 patients) in the treatment group versus 10.28% (36 patients) in control group (RR: 0.58, 95% CI: 0.33, 0.97, P=0.037; ARR: -0.043, 95% CI: 0.06, 0.01). Most of the primary and secondary endpoints were occurred in 18 months (84.50% in the treatment group versus 78.10% in the control group).
CONCLUSIONCHMs for benefiting qi and activating blood circulation adjunctive to conventional treatment improved clinical outcomes for patients with ACS after PCI in long-term follow-up.

BACKGROUNDPatients on hemodialysis have a high-mortality risk. This study analyzed factors associated with death in patients on maintenance hemodialysis (MHD). While some studies used baseline data of MHD patients, this study used the most recent data obtained from patients just prior to either a primary endpoint or the end of the study period to find the characteristics of patients preceding death.
METHODSParticipants were selected from 16 blood purification centers in China from January 2012 to December 2014. Patients' data were collected retrospectively. Based on survival status, the participants were divided into two groups: survival group and the death group. Logistic regression analysis was performed to determine factors associated with all-cause mortality.
RESULTSIn total, 4104 patients (57.58% male, median age 59 years) were included. Compared with the survival group, the death group had more men and more patients with diabetic nephropathy (DN) and hypertensive nephropathy. The patients preceding death also had lower levels of diastolic blood pressure, hemoglobin, serum albumin, serum calcium, serum phosphate, Kt/V, and higher age. Multivariate analysis revealed that male sex (odd ratio [OR]: 1.437, 95% confidence interval [CI]: 1.094-1.886), age (OR: 1.046, 95% CI: 1.036-1.057), and presence of DN (OR: 1.837, 95% CI: 1.322-2.552) were the risk factors associated with mortality. High serum calcium (OR: 0.585, 95% CI: 0.346-0.989), hemoglobin (OR: 0.974, 95% CI: 0.967-0.981), albumin (OR: 0.939, 95% CI: 0.915-0.963) levels, and dialysis with noncuffed catheter (OR: 0.165, 95% CI: 0.070-0.386) were protective factors based on a multivariate analysis.
CONCLUSIONSHemodialysis patients preceding death had lower hemoglobin, albumin, and serum calcium levels. Multivariate analysis showed that male sex, age, DN, low hemoglobin, low albumin, and low serum calcium were associated with death in hemodialysis patients.

BACKGROUND: A Lenke3 type adult idiopathic scoliosis finite element model was established successfully using Mimics software. However, whether the model fits the actual conditions of individualized patients still requires a further revision and validation.OBJECTIVE: To modify and validate the Lenke3 type adult idiopathic scoliosis finite element model by finite element analysis software.METHODS: Based on the characteristics of Lenke3 adult idiopathic scoliosis model, the three-factor and three-level orthogonal experiment was used to optimize the finite element model, making it more close to the actual one. The vertebrae at T1-T4, T5-T8 and L6-S1 levels (sacral lumbarization) were loaded to simulate left and right lateral flexion,as well as extension and flexion, and the range of motion when left and right rotation were compared with Busscher and Yamamoto experiments in vitro.RESULTS AND CONCLUSION: (1) According to the orthogonal experiment, the mean difference and range of each factor and each level were calculated, and finally A1B2C3 combination was the optimal one that can make the model largely consistent with the real situation. The difference in Cobb angles between the clinical lateral flexion test and the parameter pre-modified model simulation was 54.44°, which was decreased to 2.11° after modification. Moreover, the maximum difference in each scoliosis Cobb angle of the modified model was 4.29°. (2) The simulation results of the modified model when compared with the X-ray images when left and right lateral flexion, the two data obeyed normal distribution, so the paired t test was used: left lateral flexion, P =0.082 (P > 0.05); right lateral flexion, P=0.421 (P > 0.05);supine position, P=0.160 (P > 0.05). (3) The range of motion at T1-T4 segments was as followings: left flexion, 3.25°;right flexion, 3.32°; anteflexion 2.52°; extension, 2.89°; left rotation, 3.73°; right rotation 3.76°; the range of motion at T5-T8 segments: left flexion, 1.39°; right flexion, 1.43°; anteflexion 1.35°; extension, 1.34°; left rotation 2.09°; right rotation 2.11°; the range of motion at L6/S1: left flexion: 5.17°; right flexion: 5.19°; anteflexion: 8.92°; extension: 7.35°; left rotation: 1.41°; right rotation: 1.42°. The results were almost consistent with Busscher and Yamamoto experimental results. (4) To conclude, the model is in good agreement with the patient's actual properties after modification. The modified model has good reliability and validity, and provides valid data platform for simulating clinical operation in the future.

OBJECTIVE: To investigate the variation of pelvic radius and related parameters in low-grade isthmic lumbar spondylolisthesis. METHODS: Seventy-four patients with isthmic lumbar spondylolisthesis and 47 controls were included in this study. There were 17 males and 57 females between 30 and 66 years of age, including 30 with grade I slippages and 44 grade II slippages; diseased levels included 34 cases on L4 and 40 cases on L5. Thoracic kyphosis (TK), the pelvic radius (PR), the pelvic angle (PA), pelvic morphology (PR-S1), and total lumbopelvic lordosis (PR-T12) were assessed from radiographs. RESULTS: Statistically significant differences were found for the PA, PR-T12, and PR-S1 (24.5±6.6°, 83.7±9.8°, and 25.4±11.2°, respectively) of the patients with spondylolisthesis and the healthy volunteers (13.7±7.8°, 92.9±9.2°, and 40.7±8.9°, respectively). The TK/PR-T12 ratios were between 0.15 and 0.75. However, there were no differences in all the parameters between the L4 and L5 spondylolysis subgroups (p>0.05). The TK and PR-S1 of grade II were less than grade I, but the PA was greater. The PR-T12 of female patients were less than male patients, but the PA was greater (p<0.05). CONCLUSION: Pelvic morphology differed in patients with low-grade isthmic lumbar spondylolisthesis compared to controls. Gender and the grade of slippage impacted the sagittal configuration of the pelvis, but the segment of the vertebral slip did not. Overall, the spine of those with spondylolisthesis remains able to maintain sagittal balance despite abnormal pelvic morphology.

BACKGROUNDHypotension induced by combined spinal epidural anesthesia in parturient with hypertensive disorders of pregnancy (HDP) can easily compromise blood supply to vital organs including uteroplacental perfusion and result in fetal distress. The aim of this study was to investigate whether the goal-directed fluid therapy (GDFT) with LiDCO rapid system can improve well-being of both HDP parturient and their babies.
METHODSFifty-two stable HDP parturient scheduled for elective cesarean delivery were recruited. After loading with 10 ml/kg lactated Ringer's solution (LR), parturient were randomized to the GDFT and control group. In the GDFT group, individualized fluid therapy was guided by increase in stroke volume (ΔSV) provided via LiDCO rapid system. The control group received the routine fluid therapy. The primary endpoints included maternal hypotension and the doses of vasopressors administered prior to fetal delivery. The secondary endpoints included umbilical blood gas abnormalities and neonatal adverse events.
RESULTSThe severity of HDP was similar between two groups. The total LR infusion (P < 0.01) and urine output (P < 0.05) were higher in the GDFT group than in the control group. Following twice fluid challenge tests, the systolic blood pressure, mean blood pressure, cardiac output and SV in the GDFT group were significantly higher, and the heart rate was lower than in the control group. The incidence of maternal hypotension and doses of phenylephrine used prior to fetal delivery were significantly higher in the control group than in the GDFT group (P < 0.01). There were no differences in the Apgar scores between two groups. In the control group, the mean values of pH in umbilical artery/vein were remarkably decreased (P < 0.05), and the incidences of neonatal hypercapnia and hypoxemia were statistically increased (P < 0.05) than in the GDFT group.
CONCLUSIONSDynamic responsiveness guided fluid therapy with the LiDCO rapid system may provide potential benefits to stable HDP parturient and their babies.
