ABSTRACT

OBJECTIVE@#To investigate the expression of peptidylarginine deiminase 4 (PADI4) during the process of differentiation into granulocyte of NB4 cells induced by all-trans-retinoic acid (ATRA) and whether PADI4 is involved in the inflammatory cytokines expression.@*METHODS@#Granulocyte differentiation model of NB4 cells induced by ATRA was established. The cell morphology changes were observed by Wright-Giemsa staining. The expression of cell differentiation marker CD11b was analyzed by flow cytometry. The mRNA and protein expression of PADI4 was detected by RT-PCR and Western blot, respectively. The expression of tumor necrosis factor (TNF) α and interleukin (IL) 1β was analyzed by ELISA, and also examined with the knockdown of PADI4 expression by siRNA.@*RESULTS@#After NB4 cells induced by ATRA, the cytoplasm increased and the ratio of nuclear to cytoplasmic was reduced. Nuclear dented, and rod-shaped nucleus, lobulated phenomenon increased (P<0.05). Flow cytometry analysis results showed that the cell surface molecule CD11b expression increased (P<0.01). RT-PCR and Western blot showed the expression of PADI4 increased at both transcriptional and translational levels during the process of the differentiation. ELISA showed TNF-α and IL-1β secretion increased in differentiated macrophages, while they could be inhibited by PADI4-specific siRNA.@*CONCLUSION@#During the differentiation into granulocyte of NB4 cells induced by ATRA, PADI4 expression increased. Furthermore, PADI4 appeared to play a critical role in inflammatory cytokines secretion.

ABSTRACT

To establish and validate the design space of the Digeda-4 flavored decoction( DGD-4D) extraction process by using the quality by design( Qb D) concept. With DGD-4D decoction pieces as a model drug,with the transfer rate of aesculin,picroside I,picroside Ⅱ,geniposide and the yield of extract as critical quality attributes( CQAs),the single factor experiment design was used to determine the level of each factor; the Plackett-Burman experiment design was used to select the critical process parameters( CPPs);and the Box-Behnken experiment design was used to optimize the extraction process. The design space of the DGD-4D extraction process was established,and finally,four experimental points were selected to verify the established model. The single factor experiment determined the levels of each factor,including soaking time 60 min and 30 min,water adding volume 12 times and 8 times,extraction time 90 min and 30 min,number of extraction times 3 times and 1 time,as well as extraction temperature 100 ℃ and 90 ℃.By Plackett-Burman experimental design,the DGD-4D water addition,extraction time and number of extraction times were determined to be CPPs. The Box-Behnken experimental variance analysis showed that P of the regression model was less than 0. 01 and the misstated value was more than 0. 01,indicating that the model had good predictive ability,and the operation space of CPPs in the DGD-4D extraction process was determined as follows: the amount of water addition was 10-12 times; extraction time 50-80 min; and number of extraction times was 3 times. The design space of DGD-4D extraction process based on the concept of Qb D is conducive to improving the stability of product quality and laying a foundation for the future development of DGD-4D.

ABSTRACT

For qualitative and quantitative analysis of related substances in clotrimazole cream, HPLC-Q-TOF spectrometer was used to analyze the fragmentation pathways and identify structures of the related substances. Five related substances named by BP (2018) were identified as impurity A ((2-chlorophenyl)-diphenylmethanol), impurity B (para-clotrimazole isomer), impurity E (2-chlorobenzophenone), impurity F (1-tritylimidazole) and impurity 4 (9-(2-chlorophenyl)-fluorene), respectively, by using impurity references matching and comparison with the literature data. Four related substances were detected in clotrimazole cream except impurity E, and 9-(2-chlorophenyl)-fluorene is the first identified impurity in this preparation. To establish an HPLC method for determination of the related substances in Clotrimazole Cream, the Agilent Poroshell Bonuns RP column was used (100 mm×4.6 mm, 2.7 μm) with UV detection at 215 nm. The mobile phase was acetonitrile-10 mmol·L-1 dipotassium phosphate buffer (adjusted with phosphoric acid to pH of 5.80) with a flow rate of 1.0 mL·min-1. Gradient elution was used. The column temperature was maintained at 40℃. A good linear behavior was achieved between component's concentrations and peak area for impurity A, B, E, F within the range of 0.20-10.02 μg·mL-1, 0.20-10.00 μg·mL-1, 0.20-10.10 μg·mL-1, 0.10-5.01 μg·mL-1 with the correlation coefficients were 0.999 7, 1.000 0, 1.000 0, 0.999 9, respectively. The average recoveries were 94.3%, 95.0%, 100.0%, 99.6% with RSDs were 2.8%, 2.2%, 1.1%, 2.7%, respectively (n=9). LOQ were 200.4, 200.0, 202.0, 100.2 ng·mL-1, respectively. LOD were 57.25, 57.14, 57.71, 28.63 ng·mL-1, respectively. The developed method was simple, rapid, accurate and effective for testing related substances in clotrimazole cream to control its quality, ensuring the safety of clinical medication.

ABSTRACT

Aim To observe the effect of laminarin L01 on the expression of eNOS and iNOS in aorta of rats with chronic inflammation induced by LPS. Methods Chronic inflammatory rat models were prepared by tail vein injection low dose LPS(0.4 mg·kg-1) once a week for four weeks. The rats were randomly divided into five groups. After the first injection of LPS, the DXM group was intraperitoneally injected with dexam-ethasone (10 mg·kg-1). L01 high,medium and low dose groups were intraperitoneally injected with L01 (50,30,10 mg·kg-1). The LPS group was injected intraperitoneally with equal volume of normal saline once a day. Another control group, only injection of normal saline, a total of four weeks. After the last administration,the number of whole white blood cells (WBC) was counted. ELISA was used to measure the hs-CRP in serum. The expressions of eNOS,iNOS and COX-2 mRNA were detected by RT-PCR. Results After four weeks of administration of L01, the number of WBC and the level of serum hs-CRP in chronic in-flammatory rats were significantly decreased. The ex-pression of eNOS was up-regulated, and iNOS and COX-2 expressions were down-regulated. Conclusions Laminarin L01 may regulate the expression and re-lease of endothelium-derived relaxing factor stimulated by LPS,and improve the endothelium-dependent dias-tolic function of aorta, thus protecting the damage of vascular endothelium.

ABSTRACT

Aim To study the effect of puerarin( Pue) against myocardial ischemia/reperfusion injury and in-volved mitochondrial mechanism. Methods Anoxia/reoxygenation( A/R) injury model was established in H9c2 cell. Recombinant plasmid pFLAG-VDAC1 was constructed. Cells were randomly divided into 4 groups, normal control group ( Control) , A/R group, puerarin group ( Pue + A/R ) , and pFLAG-VDAC1-Pue group. Real-time PCR was used to investigate the expression of VDAC1 at mRNA level, and the expres-sion of protein level was detected by Western blot. LDH and CK activities were measured by automatic bi-ochemical analyzer. Mitochondrial membrane potential ( Δψm) and cell apoptosis were observed by flow cy-tometry method. Mitochondrial swelling test was used to detect the opening of mitochondria permeability tran- sition pore ( mPTP) . Results Compared with control group, the expression of VDAC1 and mRNA was up-regulated in A/R group, LDH and CK activity were el-evated, and then mPTP opened, Δψm collapsed, cell apoptosis was significantly increased. Puerarin pre-treatment can lower the expression of VDAC1, main-tain Δψm, prevent the opening of mPTP, and reduce apoptosis. However, the protective effect of Puerarin could be cancelled by transfection of pFLAG-VDAC1. Conclusions The cardioprotection of Puerarin against A/R injury is closely related to down-regulation of VDAC1 and prevention of mPTP opening.

ABSTRACT

<p><b>BACKGROUND</b>In cardiac surgery, elevation of procalcitonin (PCT) could be observed postoperatively in the absence of any evidence of infection and also seems to be a prognostic marker. PCT levels measured in patients undergoing Type A aortic dissection (TAAD) were used to determine prognostic values for complications and surgical outcomes.</p><p><b>METHODS</b>Measurements of PCT, C-reactive protein (CRP), and leukocyte count were observed in TAAD surgery patients (n = 251; average age: 49.02 ± 12.83 years; 78.5% male) at presurgery (T0) and 24 h (T1), 48 h (T2), and 7 days (T3) postsurgery. PCT clearance (PCTc) on days 2 and 7 was calculated: (PCTday1- PCTday2/day7)/PCTday1 × 100%. Endotracheal intubation duration, length of stay (LOS) in the Intensive Care Unit (ICU)/hospital, and complications were recorded.</p><p><b>RESULTS</b>PCT peaked 24 h postsurgery (median 2.73 ng/ml) before decreasing. Correlation existed between PCT levels at T1 and duration of cardiopulmonary bypass (P = 0.001, r = 0.278). Serum PCT concentrations were significantly higher in nonsurvivor and multiple organ dysfunction syndrome groups on all postoperative days. PCT levels at T1 correlated with length of time of ventilation support and ICU/hospital LOS. Comparing PCT values of survivors versus nonsurvivors, a PCT cutoff level of 5.86 ng/ml at T2 had high sensitivity (70.6%) and specificity (74.3%) in predicting in-hospital death. PCTc-day 2 and 7 were significantly higher in survivor compared with nonsurvivor patients (38% vs. 8%, P= 0.012, 83% vs. -39%, P< 0.001). A PCTc-day 7 cutoff point of 48.7% predicted survival with high sensitivity (77.8%) and specificity (81.8%).</p><p><b>CONCLUSIONS</b>PCT level and PCTc after TAAD surgery might serve as early prognostic markers to predict postoperative outcome. PCT measurement may help identify high-risk patients.</p>

ABSTRACT

Objective: To investigate the dynamic changes of mitofusin-2 (Mfn2) expression in rat cerebral arteries after experimental subarachnoid hemorrhage (SAH) and to reveal the relationship between Mfn2 and cerebral vasospasm (CVS). Methods: A SAH model was induced by endovascular perforation of the intracranial portion of the internal carotid artery. One hundred and forty six male SD rats were randomly divided into six groups; sham group and SAH groups which were sacrificed at different time points (24 hours, 48 hours, 72 hours, 7days and 14days). Mortality, neurobehavioral score and brain water content were measured. Histology was conducted to observe the morphological changes. Western blotting and RT-PCR were performed to measure the Mfn2 protein and mRNA changes of the major cerebral arteries at different time points after SAH. Results: Blood clot surrounded the basilar artery gradually dissipated after SAH. HE staining showed that the most severe morphological vasospasm in basilar arteries was observed at the 24th hour after SAH. No positive immunohistochemical staining of Mfn2 was shown in the media layer of basilar artery at the 7th day after SAH. Western blotting showed that Mfn2 protein was remarkably increased at the 48th hour and the 72th hour after SAH compared to sham groups (P < 0. 05) and significantly decreased at the 7th day after SAH (p < 0. 05). The protein level at the 14th day after SAH was almost the same level with the sham and SAH 24 hours groups. The mRNA level changed in the same tendency as the protein level. Conclusion: This study indicate that Mfn2 plays essential roles in both acute and delayed CVS which may provide a theoretical basis for understanding of the mechanism of the CVS after SAH.

ABSTRACT

<p><b>BACKGROUND</b>The mechanism of cerebral vasospasm following subarachnoid haemorrhage (SAH) is not understood. Here, we hypothesized that apoptosis of endothelial cells induced by p53 and its target gene em dash p53 upregulated modulator of apoptosis (PUMA) played an important role in development of cerebral vasospasm. We also observed the effects of a p53 inhibitor, pifithrin-alpha (PFT-alpha), on reducing the expression of p53 and PUMA, consequently decreasing the apoptosis of endothelial cells and alleviating cerebral vasospasm.</p><p><b>METHODS</b>Male Sprague-Dawley rats weighing 300-350 g were randomly divided into five groups: a control group (sham surgery), a SAH group, a SAH+dimethyl sulfoxide (DMSO) group, a SAH + PFT-alpha (0.2 mg/kg) group and a SAH + PFT-alpha (2.0 mg/kg) group. PFT-alpha was injected intraperitoneally immediately after SAH. Rats were sacrificed 24 hours after SAH. Western blot and immunohistochemical staining were used to detect the levels of p53, PUMA and caspase-3 protein. In addition, mortality and neurological scores were assessed for each group. Statistical significance was assured by analysis of variance performed in one way ANOVA followed by the Tukey test. The neurological and mortality scores were analyzed by Dunn's method and Fisher exact test, respectively.</p><p><b>RESULTS</b>After SAH, Western blot and immunohistochemical staining showed the levels of p53, PUMA and caspase-3 in the endothelial cells and the numbers of TdT mediated dUTP nick end labelling (TUNEL) positive endothelial cells were all significantly increased in the basilar arteries (P<0.05), but significantly reduced by PFT-alpha (P<0.05). These changes were accompanied by increasing diameters and declining wall thickness of basilar arteries (P<0.05), as well as reduced mortality and neurological deficits of the rats (P<0.05).</p><p><b>CONCLUSIONS</b>PFT-alpha could protect cerebral vessels from development of vasospasm and improve neurological outcome as well as reduce the mortality via suppressing apoptosis induced by p53 in the endothelial cells of cerebral vessels.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To study the characteristics of inheritance and epidemiology of gallstone disease in one pedigree.</p><p><b>METHODS</b>A gallbladder disease-specific questionnaire was administered to all family members to ascertain histories of cholecystectomy and other medical conditions as well as anthropometrical data. Laboratory examination and ultrasonography were performed to determine the existence of gallstone.</p><p><b>RESULTS</b>One hundred and thirteen members of four generations in the index family were enrolled in the study. The prevalence of gallstone in females (34.48%) was higher than in males (23.64%) but with no significant difference. The prevalence in the second and third generations (52%) was higher than in others (20%) (P < 0.05). The heritability and standard error showed as 86.38% +/- 46.46% in I generations. Body mass index, histories of hypertension, hyperlipidemia and blood glucose were positively related to gallstone disease (P = 0.012, < 0.01, 0.017, 0.043, respectively) in this family. Gallstone disease was not significantly related to history of diabetes, daily alcohol or diet habit. Plasma cholesterol and triglyceride levels were not correlated with gallstone disease.</p><p><b>CONCLUSION</b>Gallstone disease presented aggregation in the family and was in accordance with the characteristics of autosomal dominant inheritance.
