Objective To evaluate the diagnostic value and limits of 64-slice spiral coronary artery imaging,by com- parison with selective coronary angiography,in detection of coronary heart disease.Methods Fourty-two patients sus- pected CAD were performed 64-slice spiral CT coronary imaging and selective coronary artery angiography in two weeks, comparative analysis of results were progressed consequently.Results The sensitivity,specificity and positive and nega- tive predictive value to identify≥50% stenosis branches was 90.5%,96.6%,85.9% and 97.8%,respectively.The sen- sitivity,specificity and positive and negative predictive value to identify≥75% stenosis branches was 93.5%,98.9%, 87.9% and99.4%,respectively.Conclusion As a noinvasive quantitative assessment of coronary artery stenoses exami- nation,64-slice spiral CT is a valuable method to detect and diagnose the disease of coronary artery,but its clinical use maybe presently be limited due to image quality in a number of cases.

Objective: To establish a method for the determination of curcumine and berberine hydrochloride in Shangke Dieda paste. Methods:An HPLC method was adopted to determine the content of curcumine and berberine hydrochloride in Shangke Dieda paste. For curcumine, the column was InertSutain C18 (250 mm × 4. 6 mm,5 μm); the mobile phase was acetonitrile and 4% acetic acid solution (44 ∶56);the flow rate was 1. 0 ml·min-1;the column temperature was 25℃;the detection wavelength was 430 nm;the sample size was 10μl. For berberine hydrochloride, the column was InertSutain C18 (250 mm × 4. 6 mm,5μm);the mobile phase consisted of acetonitrile-0. 1% phosphoric acid (44 ∶56, 0. 2 g dodecyl sodium sulfate was added to 100 ml solution); the flow rate was 1. 0 ml·min-1;the column temperature was 25℃ ;the detection wavelength was 345 nm;the sample size was 10 μl. Results:A good linear correlation was obtained within the range of 0.01-0.50 μg (r =0.999 3) for curcumin and 0.02-0.16 μg(r =0. 999 9) for berberine hydrochloride. The average recovery was 101. 03% with RSD of 1. 75% for curcumin and 99. 20% with RSD of 0. 64% for berberine hydrochloride (n=9). Conclusion:The established method is simple, accurate, sensitive and specific, which can be used for the quality control of Shangke Dieda paste.

Objective To design and synthesize derivatives of wanpeinine A, the main steroidal alkaloid isolated from the plant Fritillaria shuchengensis, and further study on the structure-activity relationship of the steroidal alkaloid. Methods Acylation and alkylation were used to synthesize the derivatives and their structures were identified via NMR and MS.Results The acylation of wanpeinine A (1) produced 3β,6α-diacetylwanpeinine A (2), 3β,6α-dipropionylwanpeinine A (3), 3β,6α-dichloracetylwanpeinine A (4), 3β,6α-dibenzoylwanpeinine A (5), and 3β-methoxyacylwanpeinine A (6). The alkylation of wanpeinine A formed 3β,6α-dimethoxymethylwanpeinine A (7). Conclusion All compounds are new except for 3β,6α-diacetylwanpeinine A.

OBJECTIVE: To investigate the compatibility of hollow hydroxypropyl starch capsules with drug particles of ofloxacin. METHODS: The capsules were placed in conditions of high temperature of 40℃ or high humidity of (75 ± 5)% RH for 5 and 10 d, respectively. The contents and related substances were determined by high performance liquid chromatography (HPLC), and the changes in the drug appearance and colors were observed. RESULTS: After being stored under the conditions of high temperature and high humidity for 5 and 10 d, the contents of ofloxacin were in the range of 90% - 110%, and no new impurities were detected, which conformed to the quality standard of ofloxacin capsules in the Chinese Pharmacopoeia 2010 edition. CONCLUSION: There is good compatibility between ofloxacin and hollow hydroxypropyl starch capsules, which is consistent with the test results of gelatin capsules.

OBJECTIVE: To establish a method for determination of D(-) sulbenicillin sodium in sulbenicillin sodium for injection by HPLC/MS. METHODS: The analysis was performed on a SHIMADZU VP-ODS column with mobile phase consisting of 0.01 mol·L-1 ammonium acetate solution-methanol (90:10) at a flow rate of 0.6 mL·min-1. The detection was performed by Multiple Reaction Monitoring (MRM) scanning mode with ESI negative ion mode. RESULTS: D(-) and L(+) sulbenicillin could be effectively separated. Good liner relationship was achieved when the concentration of D(-) sulbenicillin was in the range of 1.03-51.90 μg· mL-1 (r = 0.9997). The average recovery rate was 99.98% at three levels (RSD = 0.30%, n = 9). CONCLUSION: The MRM method is accurate, reliable, and can be used for the determination of D(-) sulbenicillin sodium in sulbenicillin sodium for injection.

Middle East respiratory syndrome coronavirus (MERS-CoV) was identified as a novel human coronavirus and posed great threat to public health world wide,which calls for the development of effective and safe vaccine urgently. In the study, peptide epitopes tagrgeting spike antigen were predicted based on bioinformatics methods. Nine polypeptides with high scores were synthesized and linked to keyhole limpet hemocyanin (KLH). Female BALB/C mice were immunized with individual polypeptide-KLH, and the total IgG was detected by ELISA as well as the cellular mediated immunity (CMI) was analyzed using ELIs-pot assay. The results showed that an individual peptide of YVDVGPDSVKSACIEVDIQQTFFDKTWPRPIDVSKADGI could induce the highest level of total IgG as well as CMI (high frequency of IFN-γ secretion) against MERS-CoV antigen in mice. Our study identified a promising peptide vaccine candidate against MERS-CoV and provided an experimental support for bioinformatics-based design of peptide vaccine.

Objective To observe the perioperative management of cardiac surgery and extracorporeal circulation method in patients with glucose-6-phosphate dehydrogenase deficiency(G6PD).Methods Ten patients with G6PD deficiency underwent uneventful cardiac surgery procedures between January 2005 and December 2010.Twenty patients who had non-G6PD deficiency were as a control group,the selected conditions were the same gender,age,body mass,the risk of heart disease surgery.The preoperative management in patients with G6PD deficiency mainly focused on avoiding the drugs implicated in haemolysis,reducing the surgical stress,using moderate hypothermia extracorporeal circulation and enhancing blood conservation.Observed indicators included the assisted ventilation time,urine volume,the drainage volume of chest tube,the amount transfusion of red blood cells and plasma,the level of hemoglobin and serum total bilirubin in the 2nd day after surgery,ICU stay.Results Compared with the control group,patients with G6PD deficiency had no significant difference in duration of ventilation after the operation,drainage,urine,Hgb,bilirubin levels,and blood transfusion[(9.3 ± 4.5)h vs (8.6 ± 5.7)h,(2100 ±670)ml vs (1950 ± 490) ml,(253 ± 146)ml vs (260 ± 120)ml,(1.3 ± 1.0)U vs (1.8 ± 1.2)U,(96 ± 25)g/L vs (99 ± 12)g/L,and (24 ± 8)μmol/L vs (27 ± 1 l)μmol/L,t =0.978,2.032,1.257,0.891,2.182,2.271,and 1.329,all P ＞ 0.05].The duration of ICU discharge was significantly longer in the glucose-6-phosphate dehydrogenase deficient group[ (2.6 ± 0.6)d vs (1.8 ± 1.5)d,t =2.704,P ＜ 0.05].Conclusions Cardiac surgery can be performed safely in patients with G6PD deficiency with enhanced perioperative management.

Magnetic resonance imaging ( MRI ) findings were studied in 19 patients with non-dementia Parkinson′s disease ( PD) Hoehn-Yahr Stage 1 and 1.5 and 38 healthy subjects.The width and area of pars compacta of substantia nigra ( SNc) , substantia nigra ( SN) and midbrain were measured.The width and area ratios of SNc to SN were calculated.Compared with controls, the widths of right SNc was narrower, bilateral ratios of SNc to SN width were decreased in PD group.As to the area of substantia nigra, there was no significant difference between PD and controls.The width of left SN and the ratio of right SNc to SN width was negatively correlation with age of patients.The ratio of left SNc to SN width, the area of bilateral SNc and left SN, as well as the ratio of right SNc to SN area had negative correlation with the disease duration;however, there was no correlation with gender, Hoehn-Yahr Stage, the Unified Parkinson disease rating scale score, mini mental state scale, education years, levodopa equivalent daily dose, Hamilton Depression Scale or Hamilton Anxiety Scale in PD group.The results indicate that there are bilateral structural changes of SN in unilateral PD patients, which may be more significant with increasing disease duration.The measurement of SNc width and SN area can be used as an objective indicator for diagnosis and disease progression monitoring of PD.
