ABSTRACT

OBJECTIVE:To investigate the compatibility stability of Salvianolic acid for injection (SAFI) combined with 8 kinds of common solvents. METHODS:Referring to package inserts,SAFI was collected and combined with 0.9% Sodium chlo-ride injection,5% Glucose injection,10% Glucose injection,Compound sodium chloride injection,Mannitol injection,Glycerol fructose and sodium chloride injection,Sodium lactate Ringer's injection,Glucose and sodium chloride injection,250 mL each re-spectively,and then sealed in the dark at the room temperature. The appearance of mixtures were observed,pH value,the number of insoluble particles,maximal absorption wavelength and maximal absorbance were detected,and the contents of salvianolic acid B,rosmarinic acid,lithospermic acid and salvianolic acid Y in mixtures were determined by HPLC at 0,1,2,4,8 h after mix-ing. RESULTS:Under above condition,no obvious change was found in appearance or pH values of the mixtures within 8 h. Maxi-mal absorption wavelength ranged 284.5-286.0 nm. After mixed with Mannitol injection,the number of particles≥10μm(1-8 h af-ter mixing)and particles ≥25 μm(4-8 h after mixing)exceeded the scope of Chinese Pharmacopoeia(2015 edition);the maxi-mal absorbance changed significantly(RSD=9.17%,n=5);the relative content of salvianolic acid B,rosmarinic acid,lithosper-mic acid and salvianolic acid Y decreased by more than 10%(RSD=14.65%,6.45%,8.97%,12.49%,n=5);after mixed with Sodium lactate Ringer's injection,the relative content of rosmarinic acid and lithospermic acid changed greatly (RSD=14.57%, 7.28%,n=5);after mixed with 5% Glucose injection(4-8 h after mixing)and Glycerol fructose and sodium chloride injection(8 h after mixing),the relative content of rosmarinic acid were less than 90%(RSD=6.30%,4.86%,n=5);and the number of particles ≥25μm exceeded the scope of phamcopoeia after mixing with Glycerol fructose and sodium injection(0 h). The number of insoluble particles in other mixtures were in line with the standard of pharmacopoeia;maximal absorbance had no significant change(RSD<5%,n=5),and the relative content change of analytes were all less than 10%. CONCLUSIONS:Clinical appli-cation of SAFI combined with Mannitol injection,Sodium lactate Ringe's injection and Glycerol fructose and sodium injecrion should be avoided. After mixed with 5% Glucose injection,SAFI should be used within 4 h. SAFI can be compatible with 0.9%Sodium chloride injection,10% Glucose injection,Compound sodium chloride injection and Glucose and sodium chloride injec-tion.

ABSTRACT

Objective To evaluate the influences of the background music in operation room on the parturi-ents of first -time cesarean sections and the medical staff.Methods 204 parturients for elective cesarean sections were selected and divided into two groups according to the dates the operations:101 for the intervening group and 103 for the control group.The patients in the intervening group would enjoy both of the background music and language communication during C -section operation,while the cases in the control group would only have routine nursing.The self -evaluation of anxiety scale(SAS)and visual analogue scale(VAS)were applied to compare the degree of anxie-ty and pain during the operations.Meanwhile,the changes of averaged blood pressure and heart rate of the patients during the operations were also recorded and compared.A questionnaire survey was completed for all the medical staff who participated in the above operations.Results The SAS and VAS scores of the intervening group were (34.35 ± 7.40)points and (2.0 ±0.7)points,lower than those of the control group,which scored (47.85 ±5.58)points and (2.7 ±0.8)points.The differences between the two groups were significant(t =6.25,4.10,all P <0.05).while the averaged blood pressures and heart rates of the intervening group were (76.64 ±8.82)mmHg and (76.18 ± 12.09)times per minute respectively,which were also lower than those of the control group[(90.75 ±7.37)mmHg and (87.62 ±9.23)times per minute respectively],the differences between the two groups were significant(t =5.810,4.443,all P <0.05 ).All of the differences were statistically significant.75% of the medical staff thought background music was good for parturients and medical staff.Conclusion Background music in operation room can reduce the level of anxiety for the patients undergoing first -time cesarean section,and can reduce the degree of pain and discomfort of the patients,and also may stabilize the patients'blood pressures and heart rates,as well as regulate medical staff's mood,and improve their working efficiency.

ABSTRACT

OBJECTIVE:To explore the content variation rule and influencing factors of 5-hydroxymethylfurfural(5-HMF)in the extraction process of the herbs Schisandra chinensis and improve the quality of monitoring the extract of Schisandra chinensis. METHODS:High performance liquid chromatography was adopted to determine the contents of 5-HMF in the extracts during the extraction process (decoction,vacuum concentration,alcohol precipitation,vacuum drying,alkali adjustment),and the content variation rule was found out. For vacuum drying during which the content of 5-HMF reduced obviously,the effects of the tempera-ture and time of drying on the content of 5-HMF were studied,and the effects of vacuum drying and freeze drying on the 5-HMF contents were compared. RESULTS:The content variation trend in the extraction process of Schisandra chinensis was as follows as a large amount of 5-HMF was produced in the herbs decoction process;the content of 5-HMF increased during concentration,re-duced during the alcohol precipitation and the vacuum drying of the extracts by three times concentrate,and maintained substantial-ly unchanged during alkali adjustment. In the process of vacuum drying,the content of 5-HMF decreased with temperature rise and time extension. Freeze drying had no effect as good as that of vacuum drying in the reduction in the content of 5-HMF. CON-CLUSIONS:It is suggested that the vacuum drying of the extracts by three times concentrate at higher temperature,which may pro-duce the extract of Schisandra chinensis with lower content of 5-HMF and thus improve the quality of Schisandra chinensis extract.

ABSTRACT

Objective To evaluate the effect and side effects of Kezhi capsule in short-term treatment of nonalcoholic fatty liver disease (NAFLD). Methods 60 NAFLD cases of outpatients according to the inclusion criteria of were randomly assigned to two groups: the treated group-30cases with the prescription of Kezhi capsule , and the control group-30cases with the prescription of Xuezhikang. The treatment Course of taking Kezhi capusule (1.25 g, tid, po) and Xuezhikang(0.6 g, bid, po)was 24 weeks. Results After treatment in both groups we saw the significant decrease of the levels of ALT, AST, TC, TG, LDL-C, CREAT, BUN, BMI and TCM Syndromes scores, and the improvement of the ultrasonographic findings of liver steatosis. In the Xuezhikang group we saw higher decrease of TC and TG than the Kezhi capsule group with statistic difference (P < 0.05), while in Kezhi capsule group we saw higher decrease of BMI , TCM Syndromes scores and the improvement of the ultrasonographic findings of liver steatosis than the xuezhikang group with statistic difference (P < 0.05). Conclusions The results show that kezhi capsule is effective for the treatment of NAFLD without obvious side effects.

ABSTRACT

<p><b>OBJECTIVE</b>To compare the safety of anastomosis and ostomy following 2-stage definitive colonic resection when severe colonic injuries treated in the setting of damage control surgery(DCS).</p><p><b>METHODS</b>Clinical data of 67 patients with severely traumatic colonic injuries undergoing DCS at the Third Affiliated Hospital of Sun Yat-sen University between 2005 and 2013 were analyzed retrospectively. Patients were divided into the anastomosis group undergoing colonic resection and anastomosis (n=40), and the ostomy group undergoing anastomosis with a protecting proximal ostomy (n=27). Postoperative complications were compared between these two groups. The risk factors of colonic anastomosis leakage were analyzed.</p><p><b>RESULTS</b>Demographics, injury severity, physiological imbalance on admission, transfusion during the first operative procedure were similar in the two groups (all P>0.05). Rates of anastomotic leakage, intra-abdominal abscess, enterocutaneous fistula, and would infection after definitive resection were not statistically different between the two groups (all P>0.05). Colonic anasomotic leakage rates were 15.0% (6/40) in anastomosis group and 11.1% (3/27) in ostomy group without significant difference (P>0.05). Left-sided colon injuries occurred in 7 out of 9 patients with anatomotic leakage, whose proportion was significantly higher than that in those without anastomotic leakage (7/9 vs. 24/58, 77.8% vs. 41.4%, P<0.05). A prolonged peritoneal closure was also observed in patients with anastomotic leakage (median, 10 days vs. 2 days, P<0.05).</p><p><b>CONCLUSIONS</b>A strategy of diverting ostomy is not the first choice for patients suffering from severe colonic injuries in the setting of DCS. Peritoneal closure at early stage may decrease the risk of colonic anastomotic leakage.</p>

ABSTRACT

Objective To investigate the effect of desflurane pretreatment on the density of muscarinic (M)-receptors on anoxic/reoxygenated rat cardiac myocytes. Methods Myocytes were obtained from ventricle of 2-3 day SD rats and incubated for 3 days. Then they were randomly allocated to one of 5 groups: group I received no treatment and served as control ( n = 5); group Ⅱ underwent 2 h hypoxia (liquid culture medium was insufflated with a gas mixture of 1 % CO2 , 1 % O2 and 98% N2) followed by 1h reoxygenation ( n = 6) ; group Ⅲ was pre-treated with 1.5 MAC desflurane (9% ) for 20 min, followed by 10 min washout before the same duration of hypoxia/reoxygenation as in group II ( n = 6) ; group IV underwent longer duration of hypoxia (48 h) followed by 24 reoxygenation ( n = 5) ; group V was pre-treated with 1.5 MAC desflurane (9% ) for 20 min followed by 10 min washout, then underwent longer duration of hypoxia/reoxygenation as in group IV ( n = 5) . The density of M-receptors was measured by the radio-ligand binding assay (RLBA) .Results The density of M-receptors was significantly lower in group Ⅱthan that in group I ( P
