Objective To explore the effects of Atorvastatin and Simvastatin on serum levels of lipid,high sensitive C-reactive protein (hs CRP)and ventricular remodeling in patients with acute coronary syndromes(ACS).Methods In this prospective study,96 patients with acute coronary syndrome were admitted in our hospital from December 2014 to September 2016.In the prospectively study,they were randomized into Atorvastatin group(Atorvastatin 20 mg daily,n =48) and Simvastatin group(Simvastatin 40 mg daily,n=48),and serum levels of hs CRP,lipids and changes in myocardial function were detected and compared between two groups before and after treatment.Results The serum levels of hs-CRP and lipids were significantly lower in Atorvastatin group than in Simvastatin group at 8 weeks after treatment(P＜0.05).At the end of the treatment,the levels of left ventricular reject fraction and left ventricular end-diastolic volume index were improved (all P ＜ 0.05) in two groups,but significantly higher in Atorvastatin group [(44.8 ± 6.3) ％ and (62.7 ± 10.4)] than in Simvastatin group [(48.9 ± 6.9) ％ and (67.9 ± 10.5) respectively,all P ＜ 0.05).Conclusions Simvastatin and Atorvastatin can effectively promote the decrease in levels of blood lipids and inflammatory reaction,and help to improve the myocardial function in patients with acute coronary syndrome,but Atorvastatin effects are more significant.

Objective To investigate the potential effects of rosuvastatin on white matter lesion and spatial memo?ry function in chronic hypertensive rats. Methods Fourty-nine male Sprague-Dawley rats were randomly divided into sham-operation group, vehicle-treated group, and rosuvastatin-treated group (10 mg/kg).A model of stroke-prone reno?vascular hypertensive rat (RHRSP) was induced by using the two-kidney two clip method in the vehicle-treated group and the rosuvastatin-treated group. Blood pressure was monitored regularly. Morris water maze experiment was conduct?ed to assess spatial memory function. Luxol fast blue stanning was used to examine the degree of leukoaraiosis. Immuno?fluorescence and electron microscopy was used to detectβ-amyloid deposits. TUNEL staining was used to assess apopto?sis. Results The blood pressure of RHRSP increased progressively after operation.Blood pressure was significantly high?er in RHRSP than in sham-operation group (P<0.01). The escape latencies of the rosuvastatin-treated group were mark?edly shorter in RHRSP than in sham-operation group (P<0.01). The numbers of crossing hidden platform in the 3 groups of rats were 4.55±1.23, 1.00±0.80 and 3.79±0.95 times. There were significantly differences in numbers of crossing hid? den platform among three groups (P<0.01). Luxol fast blue stanning showed that the grading scores for WML were lower in the rosuvastatin-treated than in the vehicle-treated group (P<0.01). Rosuvastatin significantly decreased the burden of Aβdeposits(17.47±3.59 vs. 4.42±1.57,P<0.01)and the TUNEL+cells(37.84±4.73 vs. 14.42±2.43,P<0.01)in the fron?tal cortex when compared with the vehicle-treated group. Conclusions Rosuvastatin may ameliorate spatial memory func?tion through attenuation of white matter lesion, Aβdeposits and apoptosis .

ObjectiveTo construct the eukaryotic expression plasmids containing cysteine protease inhibitor (CPI) and glyceraldehydes-3-phosphate dehydrogenase (GAPDH) gene from periodic Brugia malayi (Bm),and to observe its cellular immune response in mouse.Methods pcDNA3.1 (+)-BmCPI/BmGAPDH was constructed.The recombinant plasmids were screened and identified by digestion with restriction enzyme.BALB/c mice were injected intramuscularly with a dosage of 100 μg purified recombinant plasmid DNA with GpG oligodeoxynucleotide (CpG ODN) and two same doses were administrated at 2-week intervals.pcDNA3.1 (+) and phosphate buffered solution (PBS) were used as controls.The tissue of muscles at 4 weeks after the third injection was collected and the target gene was detected by reverse transcription-polymerase chain reaction (RTPCR).Two weeks after the third immunization,the stimulation index (SI) of spleen lymphocytes of immunized mice was measured by methylthiazolyldiphenyl-tetrazolium bromide (MTT) method and the serum levels of interleukin (IL)-4 and interferon (IFN)-γ were detected by enzyme-linked immunosorbent assay (ELISA).The data were analyzed by t test.ResultsBmCPI/BmGAPDH gene in the injected muscle of the immunized mice was detected by RT-PCR. At 6 weeks after immunization,the SIot spleen T lymphocytes in pcDNA3.1 (+)-BmCPI/CpG group and pcDNA3.1 (+)-BmCPI/BmGAPDH/CpG group were 1.466 ± 0.635 and 1.610 ± 0.112,respectively,which were both higher than PBS group and pcDNA3.1( +)-CpG group (1.004 ± 0.019 and 1.078 ± 0.129,respectively) (t=64.438,45.318,42.749 and 34.314,respectively; all P＜0.05).At 4 weeks after immunization,the serum levels of IL-4 and IFN-γ of mice in pcDNA3.1 ( + )-BmCPI/BmGAPDH/ CpG group were significantly higher than those in pcDNA3.1 (+)-CpG group (t=288.053 and 76.453,respectively; both P＜0.05),while the serum level of IFN-γ was also higher than that in pcDNA3.1 (+)-BmCPI/CpG group (t=129.642,P＜0.05). ConclusionThe recombinant eukaryotic plasmid pcDNA3.1 (+)-BmCPI/BmGAPDH could be expressed in mice,and could elicit specific cellular immune responses in immunized mice.

Objective To investigate the gender difference of the plasma lactic acid(LA) levels in type 2 diabetics with normal renal and hepatic function, and the effect of metformin on LA levels in the difference gender. Methods A total of 1 021 type 2 diabetic inpatients with normal renal and hepatic functions were collected,including metformin treatment group (213 males and 210 females) and metformin non-treatment group (299 males and 299 females). LA was measured with enzyme-electrode assay. Fasting plasma glucose ( FPG), creatinine ( Cr), and alanine aminotransferase ( ALT) levels were determined. Results LA level in metformin treatment group was significantly higher than that in metformin non-treatment group [ (1.32±0.53 vs 1.14±0.49) mmol/L,P<0.01],and 61 cases had hyperlactacidemia but no lactic acidosis was found. Spearman correlation analysis showed that LA level was positively associated with gender,metformin, and body mass index( BMI) apart from Cr and ALT( P<0.01). Multivariate logistic regression analysis showed that gender,Cr,ALT,and metformin were independent correlated factors of hyperlactacidemia. LA levels in females were higher than those of males in the whole group and two groups treated or not treated with metformin (all P<0. 05 ). LA levels in females were higher compared to male in Cr and ALT subgroups,as well as age subgroups,especially with age younger than 45 years old (P=0.021). Conclusions There is gender difference of lactate level in diabetic patients,and the effect of metformin on the plasma lactate levels of different gender is varied. The plasma LA level in females,especially those approaching menopause,are prone to hoist.

Objective To construct the eukaryotic expression plasmid containing glyceraldehydes-3-phosphate dehydrogenase (GAPDH) and cysteine protease inhibitor ( CPI ) gene from periodic Brugia malayi (Bm) and to lay foundation for studying multivalent vaccines. Methods Total RNA was extracted from periodic Bin. The BmGAPDH and BmCPI genes were amplified by RT-PCR. The PCR product was cloned and then subeloned into eukaryotic recombinant plasmid vector pcDNA3.1 (+). pcDNA3.1 (+)/BmGAPDH/BmCPI was constructed. The recombinant plasmids were screened and identified by digestion with restriction enzyme and PCR amplification, and were transformed into HeLa cell subsequently. The transient expression of BmGAPDH and BmCPI were examined by RT-PCR. The expressed protein was identified by sodium dodeeylsulphate-polyacrylamide gel electrophoresis(SDS-PAGE). Results Two specific bands of around 877 bp of BmGAPDH and 621 bp of BmCPI were amplified, consistent with the expected value. The same bands were obtained by double restriction enzyme digestion of recombinant plasmids or PCR using recombinant plasmid as template. BmGAPDH and BmCPI mRNA were highly expressed in transfeeted HeLa cell. The relative molecular mass (Mr) of the recombinant protein was about 54 × 103. Conclusion The recombinant eukaryotic expression plasmid pcDNA3.1 (+)/BmGAPDH/BmCPI has been constructed successfully and the protein is expressed correctly in mammalian cell.

Objective To evaluate the safety and effect of one-way barbs line (absorbable sutures v - locTM180) in primary suturing of laparoscopic choledocholithotomy. Methods From July 2014 to June 2015, clinical data of 86 cases performed primary suturing in laparoscopic choledocholithotomy by the same performer were retrospectively analyzed. The patients were divided into three groups, One-way barbs line continuous full-thickness suture group (A group), ordinary absorption line continuous full-thickness suture group (B group) and ordinary absorption line discontinuous full-thickness suture group (C group). The bile duct suture needed time, intraoperative blood loss, postoperative eating time, postoperative hospital stay and postoperative bile fistula were compared. Results All the 86 cases underwent successful operation without T tube, and none of them received alternative open operation. Compared with group B and C, time needed for bile duct suturing in A group have statistical significance. There was no significant difference in the intraoperative blood loss, postoperative eating time, postoperative hospital stay between the three groups (P > 0.05). The incidence of postoperative bile fistula in A group were none. The incidence of postoperative bile fistula in B group was 1 case, the incidence of postoperative bile fistula in C group was 2 cases.Conclusions The method of one-way barbs line continuous full-thickness suture were simple and secure in primary suturing of laparoscopic choledocholithotomy.

Objective To evaluate the treatment effect of negative pressure wound therapy ( NPWT) followed by ultrasonic debridement surgical system ( UDSS) in patients with diabetic foot. Methods Forty-seven diabetic foot ulcer patients( WagnerⅡ~Ⅲ) were divided into two groups,of which 26 patients treated with UDSS combined NPWT,and 21 patients treated with traditional surgical debridement combined NPWT were control group. Cure rate, markedly effective rate and adverse reaction and complication were compared between two groups. Results Compared with control group,the experiment group had higher markedly effective rate in the first week(P<0. 05),and healing rates were higher in the 2th,4th,6th,12th weeks (P<0. 05). There were no differences in the adverse reactions and complications between the two groups. Conclusion UDSS combined with NPWT can accelerate wound cure,may play an important role for the treatment of diabetic foot ulcer.

Objective At present, there is no study on effect of levetiracetam(LEV) on the gray matter structure remodeling in benign epilepsy children with central temporal spikes(BECTS).The purpose of this study was to study the influence of LEV on the gray matter structure in BECTS and to evaluate the mechanism of LEV on the brain structure of BECTS through using voxel-based MRI morphological(VBM) methods.Methods From January 2014 to September 2016, twenty-four BECTS treated with LEV(LEV group), twenty-four drug-na?ve BECTS(untreated group) and twenty-four normal children(normal group) consulted in department of Neurology, Nanjing Children′s Hospital and the Nanjing Military Region, Nanjing General Hospital were continuously included to receive three-dimensional T1-weighted imaging with 3T MRI and the gray matter volume was calculated by VBM.We compared the difference of grey matter volumes of the three groups and analyzed their correlation with epilepsy duration, age of onset and medication time and other clinical index.Results Compared with the normal group, the grey matter volume of bilateral thalamus were decreased, and the volume of bilateral Rolandic areas, anterior insula/frontal operculum/frontal triangle, left supplementary motor area, paracentral lobule, precentral gyrus, superior frontal gyrus and right middle frontal gyrus were increased in the untreated group, but the grey matter volume of the bilateral Rolandic areas, frontal operculum and left supplementary motor area were decreased in the LEV group.Compared with the untreated group, the grey matter volume of bilateral supplementary motor, left paracentral lobule, precentral gyrus, bilateral anterior insula/frontal operculum/frontal triangle, left superior frontal gyrus and right middle frontal gyrus in the LEV group were decreased.The grey matter volume of left anterior insula/frontal operculum areas was negatively correlated with the medication time in LEV group(r=-0.527, P<0.01).Conclusion T The mainly representations of BECTS are thalamic gray matter damage and epileptic-related cortical area irritation structural abnormalities, but the LEV could reshape the epilepsy-related cortical area and the gray matter in the brain area associated with clinical symptoms.
