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.

Objective To investigate the effect of different pressure CO2 pneumoperitoneum on function of liver and kidney in patients undergoing laparoscopic gastrectomy.Methods A total of sixty pa-tients,aged 40-65 years,scheduled for elective laparoscopic gastrectomy were randomly divided into three groups (n=20).The pressures of CO2 pneumoperitoneum were set at 6-8,9-11 and 12-14 mm Hg in group L,group M and group H respectively.The venous blood samples before pneumoperitoneum (T1 ),1 hour after pneumoperitoneum(T2 ),2 hour after pneumoperitoneum (T3 ),1 hour(T4 )and 24 hours(T5 )after stopping pneumoperitoneum were collected for determination of serum concentrations of NAG,Cys-C, ALT,AST,Cr,BUN and the amount of urine.pH,PaCO2 ,PaO2 were recorded at T1-T4 .Results ALT, AST,Cr and BUN were not different at T1-T5 in the three groups.Compared with group L,the concentra-tion of NAG and Cys-C at T2-T5 were significantly higher in the group M and H (P <0.05).Compared with group L,the amount of urine at T2-T5 was significantly lower in the group M and H (P <0.05 ), PaCO2 was significantly increased in the group H and M at T2-T4 (P <0.05).Conclusion The pressure of 6-8 mm Hg CO2 pneumoperitoneum can alleviate the damage of function of liver and kidney in patients un-dergoing laparoscopic gastrectomy.

0.05).Our results showed that,for recommended oral doses of ciprofloxacin and moxifloxacin,44.2% of E.coli isolates from the intestine of the health population,and 29.5%,18.7% and 10.7% of isolates from the three sterile sites of the patients,would be selected as resistant mutants.When ciprofloxacin and moxifloxacin were taken by injection route,the ratio of the selection of resistant mutants would be 9.3% for E.coli isolates from the intestine of the health population and 8.2%,6.2% and 8.9% for the three sterile sites of the patients,respectively.The maximum attainable concentration of levofloxacin in serum showed little distinction between the oral and the other routes.CONCLUSIONS The values of MIC and MPC of three fluoroquinolones in E.coli isolates from different populations and sites show no association.The values of MPC couldn't be predicted by the MIC.The values of MPC and MPC90 of three drugs show no significant discrepancy for tested isolates,these E.coli strains are isolated from the intestine of heath persons,and from the blood,ascites,bile of patients.

OBJECTIVETo observe the effect of Feiyanning Granule (FYN) on tumor growth and cell cycle distribution in mice with Lewis lung cancer, as well as its influence on G1/S cell cycle checkpoint dominating signaling RB-E2F1 bio-axis.

METHODSModeled C57BL/6 mice were randomly divided into 6 groups: the model group (A), the DDP treated group (B) peritoneally injected with cisplatin 0.1 mg on d1, d3 and d5 after modeling, and the 4 FYN treated groups (C-F), administered via gastrogavage with FYN Decoction, and FYN Granule in small-, median- and high- dose respectively for 14 days. The tumour inhibiting rate, tumour weight, and body weight of mice were observed after treatment; cell cycle distribution was detected by flow cytometry (FCM), RB-E2F1mRNA expressions in tumour tissue were analyzed by RT-PCR, and their protein expressions by Western blot.

RESULTSTumour weight in the 5 treated groups was lower than that in the model group (P < 0.05, P < 0.01). Body weight in group E was significantly higher than that in group A and B (P < 0.05, P < 0.01). FCM analysis showed the proportion of G0/G1 phase was higher in group E than in group A, B and C (P < 0.01), and cancer cell proliferation index (PI) in group E was lower than in group B (P < 0.05, P < 0.01). RT-PCR showed mRNA level of E2F1 was lower, but that of RB was significantly higher in group E than those in group A, B and C respectively (P < 0.01). Westem blot analysis showed the protein expression of E2F1 was lower in group E and B than that in group A (P < 0.05), while the protein expression of Rb in group E was higher than that in group A, B and C (P < 0.05).

CONCLUSIONThe effect of FYN in inhibiting Lewis lung cancer growth was related to its intervention on cancer cell cycle distribution which blocks most tumor cells in G0/G1 phase. Moreover, FYN can reduce MDM2 expression, enhance P53 expression to influence cell cycle G1/S checkpoint dominating signaling, so as to achieve the effect of antagonizing lung cancer cell proliferation.

Objective To explore the impact of psychological intervention on the mental state of related donors for allogeneic hematopoietic stem-cell transplantation(HSCT). Methods 64 donors for HSCT were randomly divided into intervention and control groups (32 cases for each group). Routine preoperative health education was given to the donors in the control group and psychological intervention was adopted in the intervention group on the basis of routine health education. Zung self-rating depression scale (SDS) and self-rating anxiety scale (SAS)were used to mark the scores of the mental state of donors in both groups and heart rate, blood pressure of the donors were recorded and analyzed before and after intervention. Results Compared with those before intervention, there were no statistically significant differences in blood pressure and heart rate of the donors in the intervention group (P ＞ 0. 05); the differences were statistically significant in the comparison of blood pressure and heart rate of the donors between the two groups (P ＜ 0. 05). The scores of depression and anxiety decreased compared with those before intervention in the intervention group (P ＜ 0. 05), and the differences in the comparison of the scores were statistically significant between the two groups (P ＜ 0. 05). Conclusions Psychological intervention is the key to reduce anxiety and depression and stabilize blood pressure and heart rate of the related donors for allogeneic hematopoietic stem-cell transplantation.

OBJECTIVETo explore the clinical screening and value of vertebral artery ultrasound, Transcranial doppler (TCD), Magnetic resonance angiography (MRA) and Computed tomography angiography (CTA) in the diagnosis of cerebral arteriosclerosis combined with vertebral artery abnormalies according to vertebral artery digital subtraction angiography (DSA).

METHODSFrom January 2006 to September 2010, 186 patients with cerebral arteriosclerosis were retrospectively analyzed. Among the patients, 133 cases were males and 53 cases were females,ranged from 30 to 84 years (with a mean of 63.8 years). All the patients were estimated by DSA; 172 cases were estimated vertebral artery ultrasound and TCD; 53 cases were estimated by MRA; 25 cases were estimated by CTA. The positive results by DSA were seen as case group, while the negative results were seen as control group. The sensitivity, specificity and concordance rate among four groups were calculated.

RESULTSThe abnormality rate of vertebral artery with DSA, vertebral artery ultrasound, TCD, MRA and CTA separately was 50.00% (93/186), 30.81% (53/172), 49.42% (85/172),15.10% (8/53) and 40.00% (10/25). According to DSA standard, the sensitivity of vertebral artery ultrasound in diagnosing was 50.57%, the specificity was 89.41%, and concordance rate was 69.77%; while the sensitivity of TCD was 68.48%, the specificity was 72.50%, and concordance rate was 70.35%; the sensitivity of MRA was 21.43%, specificity was 92.00%, and concordance rate was 54.72%; the sensitivity of CTA was 63.64%,the specificity was 78.57%, and concordance rate was 72.00%.

CONCLUSIONThe reasonable and combined application of vertebral artery ultrasound, TCD, MRA and CTA is helpful for diagnosing cerebral arteriosclerosis combined with vertebral artery abnormalies. For the patients with cerebrovascular disease, cervical massage technique should be paid highly attention, which may cause vertebral artery injury and other complications.
