BACKGROUND:It is generaly recognized that cervical rotation manipulation can increase the risk of detachment of unstable plaques in carotid atherosclerosis, but few studies are reported on the influence of cervical rotation manipulation on the stable plaque in early carotid atherosclerosis. OBJECTIVE:To explore the influence of the cervical rotation manipulation on the lipid contents in carotid atherosclerotic plaque in a rabbit model of early carotid atherosclerosis. METHODS:After being fed for 15 days with normal diet, 30 male New Zealand White rabbits were further fed for 18 weeks with normal diet (n = 10; control group) or a high-fat diet containing 2% cholesterol, 10% lard and 88% normal granules to build rabbit models of early carotid atherosclerosis with stable carotid plaque (n = 20). At 14 weeks of feeding with high-fat diet, the experimental rabbits fed with high-fat diet were randomly divided into a cervical rotation manipulation group (n = 10) and a model group (n = 10). The rabbits in the cervical rotation manipulation group underwent cervical rotation manipulation to the left and right sides, once each side, with the maximal range of rotation. Total five cervical rotation manipulations, once every 3 days, were performed. RESULETS AND CONCLUSION:The 1 450 cm-1 and 1 660 cm-1 peaks of the Raman spectrum of lipid in the carotid atherosclerotic plaque of rabbit models were not distinctly present in the control group, however, they were obviously observed in the cervical rotation manipulation group and model group. Nevertheless, the relative intensity differences at spectrum characteristic peaks were not significant between cervical rotation manipulation group and model group (P > 0.05). The environmental findings indicate that the lipid content in carotid atherosclerotic plaque of rabbit models of early carotid atherosclerosis cannot be increased after short-term administration of cervical rotation manipulation.

Objective To investigate the role of bone marrow mesenchymal stem cells (MSCs) transplantation in repairing injured intestinal mucosa of acute pancreatitis.Methods MSCs were harvested and cultured from femurs of male SD rats.Twenty female SD rats were divided into three groups,and serve acute pancratitis (SAP) model was induced by intraperitoneal injection of L-arginine (2 g/kg) twice.Twelve hours after SAP model established,MSC transplantation group (n=8) were injected MSCs (5 × 106 cell/rat) through tail vein for three days,and SAP group (n=6) were injected the same volume of saline through tail vein as control.Control group (n=6) were only injected the same volume of saline without any treatment.All the rats were sacrificed at 72 hours after model established.The small intestinal tissues were taken for HE staining and pathological score,the TNF-α mRNA and IL-1β mRNA expression level in small intestine and pancreas were tested by RT-PCR.Y chromo-some (Sry) gene in pancreatic and intestinal tissue was examined by polymerase chain reaction (PCR).Results The relative expression quantity of TNF-a mRNA and IL-1β mRNA in pancreas was significant higher in SAP group and MSC transplantation group than in control group (7.22 ± 1.99,3.46± 1.75 vs 1.32 ± 1.04 ; 2.71 ± 0.56,1.92 ± 0.28 vs 0.61 ± 0.45 ),the difference was statistically significant (F=18.375,F=22.701; P＜0.05).Compared with SAP group,the expression quantity of TNF-α mRNA and IL-1β mRNA in pancreas was significantly decreased in MSC transplantation group,the difference was statistically significant (P＜0.05).The relative expression quantity of TNF-α mRNA and IL-1β mRNA in small intestine was significantly higher in SAP group and MSC transplantation group than in control group (3.93 ± 1.08,2.13 ± 0.53 vs 0.68 ± 0.42 ; 2.44 ± 1.54,1.02±0.44 vs 0.60±0.14),the difference was statistically significant (F=21.772,F=6.132; P＜0.05).The expression of TNF-αmRNA and IL-1β mRNA in MSC transplantation group was lower than that in SAP group,the difference was statistically significant (P＜0.05).Compared with SAP group,pathological score indicated that small intestine injure was slighter in MSC transplantation group (3.83±0.28 vs 2.83±0.56),the difference was statistically significant (F=12.013,P＜0.05).Sry gene could be detected in the pancreatic and intestinal tissue of MSC transplantation group.Conclusion Allogeneic MSC transplantation group can inhibit Pro-inflammatory cytokines expression in acute pancreatitis,relieve the intestinal mucosa injury and may involve in the intestinal tissue repair.

Objective To evaluate the efficacy of the retroperitoneal laparoscopic pyelolithotomy (RLP) and the percutaneous nephrolithotomy (PCNL) in treating renal pelvic stone.Methods The data of 89 patients diagnosed as renal pelvic stone were retrospectively reviewed from January 2009 to July 2016,of whom 43 patients underwent RLP and 46 underwent PCNL.Statistical analysis was performed regarding operation time,blood loss,mean hospital stay,complication rate,and stone-free rate.Results The operation time in RLP group and PCNL group was (117.5 ± 16.7) min and (118.3 ± 16.6) min,respectively,and there was no significant difference (P =0.547).For the two groups,the mean hospital stay was (4.5 ± 0.5) d and (6.1 ± 0.9) d,the mean hemoglobin decrease was (4.5 ± 1.2) g/L and (18.1 ± 3.4) g/L,the post-operative blood transfusion rate was 2.3％ and 14.0％,the post-operative septic shock rate was 0 and 9.3％,respectively,with significant difference between the two groups (P ＜ 0.05).The stone-free rate in both groups was 97.7％ and 95.3％ with no significant difference (P =0.557).Conclusions RLP has the advantages of quick recovery,less blood loss and lower complication rate than PCNL.It could be a minimally invasive option for the treatment of renal pelvic stone.

Objective To compare the effects of heat-sensitive moxibustion and ginger-partition moxibustion on refractory peripheral facial paralysis. Methods Fifty-five patients with refractory peripheral facial paralysis were randomized into heat-sensitive moxibustion group (N=28) and ginger-partition moxibustion group (N=27). For two cases dropped out during the treatment, a total of 25 cases were finally enrolled into the ginger-partition moxibustion group. Two groups received oral use of mecobalamin tablets and conventional acupuncture, and heat-sensitive moxibustion group was given heat-sensitive moxibustion and ginger-partition moxibustion group was given ginger-partition moxibustion additionally. The moxibustion was performed once a day and ten times constituted one course, the treatment covered 6 courses. The clinical effect of the two groups was evaluated by 40-score method, House-Brackmann facial neurological function evaluation standard, blink reflex ( BR) , electromyogram and electroneurography. Results ( 1) Symptoms integral was increased in both groups after treatment ( P<0.01) , and the scores of heat-sensitive moxibustion group were higher than those of ginger-partition moxibustion group ( P<0.01). ( 2) The markedly effective rate of heat-sensitive moxibustion group was 75.00% and that of ginger-partition moxibustion group was 44.00%, and there was statistically significant difference between them ( P<0.05). ( 3) The results of electrophysiological examination showed that the difference values of ipsilateral and contralateral BR R1, R2, R2’ in both groups after treatment were less than those before treatment ( P<0.01) , and the abnormal rate of electromyography for heat-sensitive moxibustion group was improved obviously after treatment ( P<0.01) . The amplitude of compound muscle action potentials ( CMAP) of orbicularis oculi/orbicularis oris at the affected side of both groups showed a decreasing trend, but the differences were insignificant between the two groups after treatment ( P>0.05). Conclusion The curative effect of heat-sensitive moxibustion for the treatment of refractory peripheral facial paralysis is better than that of ginger-partition moxibustion.

In this study, a rapid and sensitive analytical method was developed for the determination of 10 major compounds (procyanidin B1, catechin, procyanidin B2, rutin, isoquercitrin, kaempferol-3-O-rutinoside, astragalin, quercitrin, quercetin, and kaempferol) in Tetrastigma hemsleyanum by using ultra-performance liquid chromatography coupled with triple-quadrupole tandem mass spectrometry (UPLC-MS/MS) in multiple-reaction monitoring (MRM) mode. UPLC-MS/MS assay with negative ion mode was performed on a Waters CORTECS C18 (2.1 mm x 100 mm, 1.6 μm) with the mobile phase consisting of acetonitrile (A) and 0.1% aqueous formic acid (B) in gradient elution at a flow rate of 0.25 mL · min(-1) and the column temperature was set at 45 °C. Under the optimized chromatographic conditions, good separation for 10 target compounds were obtained including chiral isomer procyanidins B1 and B2 were completely separated within 8.5 min. Satisfactory linearity was achieved with wide linear range and fine determination coefficient (r > 0.996 6), the overall recoveries were ranged from 95.44%-110.40% with the RSD ranging from 2.37%-8.69%. It is the first report about simultaneous analysis of 10 major flavonoids components in Tetrastigma hemsleyanum by using UPLC-MS/MS method, which affords highly sensitive, specific, speedy and efficient method for quality control of Tetrastigma hemsleyanum

Objective To investigate the effect of prostaglandin E1 (PGE1)on alveolar cells apoptosis in rat lung impact in-jury model.Methods SD rats were divided into 3 groups (normal control group,lung injury control group and PGE1 treated group).PaO2 and pulmonary coefficient were detected after 24 h of impact.TUNEL labeling was used to evaluate apoptosis and Western blot was used to estimate protein expression levels of beclin-1,LC3 Ⅱ/LC3 Ⅰand NIX.Results After 24 h of impacting, there were obvious structural damage and pneumonedema in rat lung.Compared to normal control group,the PaO2 of lung injury control group decreased and the apoptosis of alveolar cells increased significantly(P <0.05).Furthermore,the expression levels of Beclin-1,LC3Ⅱ/LC3Ⅰ and NIX in the impacting control group were increased (P <0.05 ).In the PGE1 treated group,the PaO2 were decreased compared to normal control group(P <0.05),but these expression levels were higher significantly than lung injury control group (P <0.05).The expression levels of apoptosis,Beclin-1,LC3Ⅱ/LC3Ⅰ and NIX in the PGE1 treated group were in-creased compared to normal control group(P <0.05),but these expression levels were lower significantly than lung injury control group (P <0.05).Conclusion PGE1 could alleviate alveolar cells apoptosis after lung impacting injury,and which effect may as-cribe to PGE1 inhibiting NIX-mediated autophagy and autophagic apoptosis of alveolar cells.

Objective To investigate the expression of melatonin MT1 receptor in rats with acute necrotizing pancreatitis (ANP) and the protective effects of melatonin (MT) pre-intervention for the pancreas. Methods Fifty-four male Sprague-Dawley (SD) rats were randomly divided into three groups:sham-operation group, ANP group and MT-pretreated group. The models of ANP were induced by retrograde injection sodium taurocholate into the bili-pancreatic duct. MT group undergoing intraperitoneal injection 50 mg/kg 30 minutes before the establishment of ANP models. Four, 8 and 12 hours after the onset of operation, the levels of serum amylase and pathological changes of the pancreas were observed. The contents of malondialdehyde (MDA), superoxide dismutase (SOD) and tumor necrosis factor-alpha (TNFα) in the pancreas were measured. The expression of MT1 protein and MT1 mRNA in pancreas were separately analyzed by immunohistochemistry and real-time PCR. Results (1) Pancreatic pathological damage in ANP groups was progressive exacerbated. It was obviously ameliorated in MT group as compared with ANP group ( P ＜ 0.05 ); (2) Compared with SO group, the levels of serum amylase, MDA and TNFα in the pancreas were significantly increased in ANP group (P ＜0.05 or P ＜0.01 ). They were markedly decreased in MT group as compared with ANP group [ 12 h, (2348.00 ±278.90)U/L vs (3194. 83 ±538.10)U/L,(2.255 ± 0.472 ) μmol/L vs ( 2.960 ± 0.722 ) μ mol/L, ( 102.929 ± 29.399 ) ng/L vs ( 378. 544 ±183.454)ng/L, P ＜ 0.05 ]. The level of SOD was decreased in ANP group compared with SO group (P ＜0.05) and increased in MT group[ 12h, (11.448 ± 1.594)U/L vs (8.427 ± 1.950)U/L, P＜0.05] ;(3)Compared with SO group, the expression of MT1 protein and MT1 mRNA in ANP group were down-regulated as the severity of the disease increased ( P ＜ 0.05 ). They were significantly higher in MT group than ANP group. Conclusions Melatonin pre-intervention is able to increase SOD level and decrease MDA, TNFα levels, thereby reducing pancreatic injury. The MT1 might play an important role in the pathogenesis of ANP. MT might exert protective effects for the pancreas in ANP rats through increase the expression of MT1.

OBJECTIVETo observe the effects of different loading doses of atorvastatin calcium on the outcomes of percutaneous coronary intervention (PCI) in elderly patients with coronary heart disease (CHD).

METHODSA total of 120 CHD patients aged over 80 years were randomly assigned into 3 equal groups to receive intensive pretreatment with statin at the doses of 20, 40, or 60 mg prior to PCI performed within 48 to 72 h after admission. The changes of postoperative cardiac biochemical markers including creatine kinase isoenzyme (CKMB), troponin I (cTNI) and high-sensitivity c-reactive protein (hs-CRP) were observed and the incidence of major adverse cardiac events (MACE, including cardiac death, myocardial infarction, and target vessel revascularization) were recorded within 30 days after PCI.

RESULTSThirty-four patients in 20 mg statin group, 40 in 40 mg statin group, and 38 in 60 mg statin group completed this study. In all the 3 groups, hs-CRP level significantly increased at 12 and 24 h after PCI compared with the preoperative levels (P<0.05). The patients in 60 mg statin group showed significantly lower levels of CKMB, cTNI, and hs-CRP at 24 h after PCI than those in 20 mg statin group (P<0.05), and had also a significantly lower incidence of total MACE within 30 days after PCI (2.6% vs 26.5%, P=0.003) resulting primarily from significantly reduced myocardial infarction associated with PCI (2.6% vs 20.6%, P=0.016). The adverse drug reactions were comparable among the 3 groups (P>0.05).

CONCLUSIONSIntensive pretreatment with 60 mg/day atorvastatin calcium can significantly reduce myocardial infarction related to PCI with good safety in elderly patients with CHD.
