OBJECTIVE: To establish and a method for determination of allicin and the fingerprints of intravenous emulsion containing garlic oil. METHODS:GC method was applied to determine allicin in preparation and the fingerprints of intravenous emulsion containing garlic oil. The separation was performed on HP-5 (30 m?320 ?m?0.25 ?m) column with the flow rate of 1.0 mL?min-1 and inlet temperature of 250 ℃. The column temperature was 60～220 ℃ and rose by temperature-programmed method with N2 as carrier gas. The temperature of FID detector was 300 ℃ with furan as internal standard. RESULTS: The linear ranges of allicin were 0.05～2.4 mg?mL-1(r=0.999 8). The average recovery were 102.5% (RSD=0.41%,n=9). There were 17 mutual peaks in the fingerprints of intravenous emulsion containing garlic oil. The RSD of intra-day relative retention time and relative peak area were less than 0.05% and 8% respectively. After preparation setting for 48 h at room temperature, the RSD of relative retention time and relative peak areas were less than 0.08% and 15% respectively. The RSD of them in the replicate test were less than 0.04% and 8%, respectively. CONCLUSION: The method is accurate, reliable, simple and available for quality control of intravenous emulsion containing garlic oil

To observe the effect of aerobic exercise on the body shape,cardiovascular,physiology and biochemical indexes of elderly women,we trained 76 old women (volunteers,mean age 58 years old) from urban area of Yulin from 14th July 2005 to 14th January 2006,60 minutes every time,3 times a week. The heart rate during exercise was controlled within 110-125 times per minute. The changes in their body shape (body mass and waistline),cardiovascular function (resting heart rate and blood pressure) and biochemical indexes before and after exercise were observed. The results showed that after 24 weeks of aerobic exercise,the body mass and waistline of the subjects were decreased compared with that before exercise (P

Objective To analyze the distribution characteristics and risk factors of extended stay over 30 days at tertiary comprehensive hospitals, and explore methods of shortening average length of stay(LOS).Methods Homepage of all inpatients discharged from October 2014 to October 2015 of 31 tertiary comprehensive hospitals in Shanxi province were collected.39 234 cases of these inpatients stayed over 30 days and their case information was complete.A generalized linear model was used for risk factors analysis.Results With the extension of LOS, most of the inpatients with extended stay were found during their 30th-40th days, accounting for 50.21% of all and constituting the highest daily costs as well.The ratio of inpatients decreases with their LOS, and its distribution presents a positive skew in entirety.Distribution of inpatients over 30 days identified urban employees under medical insurance accounting for the highest ratio among all payment categories,and those from the department of orthopedics for the highest ratio among all departments, while those of diseases from injury and poisoning accounting for the highest ratio among all disease categories.The findings indicated ten important factors for extended stay, namely gender, medical payment category, ICD, inter-department transfer, nosocomial infection, and clinical pathway.Conclusions To strengthen management of specific departments and inpatients, focus on key process of medical quality, and accelerate medical insurance payment reform can effectively control extended stay.

OBJECTIVE:To investigate the stability of garlic oil-hydropropyl-?-cyclodextrin(HP-?-CD)inclusion complex.METHODS:With diallyl trisulfide(DATS)as determination index,the water solution of garlic oil HP-?-CD in-clusion complexes,freeze-drying powders of inclusion complex and the garlic oil injections were respectively subjected to il-lumination,high temperature,dilution tests and accelerated tests,and long-term sample observation tests by gas chro-matography(GC).RESULTS:The content of DATS in freeze-drying powders of inclusion complex had a minimum reduc-tion among the three under conditions of illumination and high temperature.In the accelerated tests and long-term sample observation tests,almost all the determination indexes of freeze-drying powders remained unchanged and a good stability was noted.Within10h,all the different diluents showed no significant effects on the indexes of the inclusion complex.CON-CLUSIONS:As compared with garlic oil injections,the garlic oil inclusion complex had a higher stability,freeze-drying powders of inclusion complex showed the best stability,yet the storing of which still needed to be under a proper temperature and away from light.

Objective To investigate the incidence of hearing disorder and analyse the high-risk factors with hearing injury in newborns with hyperbilirubinemia.Methods The newborns with hyperbilirubinemia who admitted to the department of neonate,were received the distortion product otoacoustic emission(DPOAE)test when they recovered from hyperbilirubinemia;those babies who didn′t pass the first test received screening again in 42 days after birth.Those babies who didn′t pass the second test received auditory brain stem response(ABR)test.Results Fifty-eight(33.2%)newborns didn′t pass the first DPOAE test among 235 newborns with hyperbilirubinemia;11(18.9%)infants didn′t pass the second DPOAE test among 58 infants;5 infants failed to pass the ABR test,the ratio of hea-ring disorder in newborns with hyperbilirubinemia was 2.13%;18(9.9%)newborns didn′t pass the first DPOAE test among 182 normal newborns,and those infants all passed the second DPOAE test.Conclusions Hyperbilirubinemia is high-risk population of hearing disorder.The congenital cytomegalovirus infection,neonatal septicemia and hemolytic disease of newborn are the high risk factors responsible for hearing disorder.All high risk newborns should recieve hearing examination regularly.

Objective Subarachnoid hemorrhage ( SAH) is a devastating disease with high fatality and morbidity and micro-glia/macrophage ( M/M) plays a vital role in SAH brain injury with complicated pathophysiological mechanism .This study was to ob-serve the effect of Nrf2 deficiency on M/M activation and M1 polarization after subarachnoid hemorrhage in mice . Meth ods We col-lected 70 wild-type ( WT) ICR mice and 35 Nrf2-knockout ( KO) mice to establish the SAH model by injecting fresh autologous blood into pre-chiasmatic cistern.WT mice were arranged into four groups: sham operation group, post operative day 1 (POD1) group, POD3 group and POD5 group.Then WT mice and Nrf2 Nrf2-knockout mice were divided into sham operation WT group , sham opera-tion KO group, SAH WT group and SAH KO group.Western blotting (WB) and immunohistochemistry (IHC) were applied to observe the activation and proliferation of M/M after SAH on WT mice .Difference in activation and M 1 polarization were observed by detecting Iba1 expression in WB and CD 16/32 +Iba1 +cells in immunofluorescence between WT and KO mice . Results Gray scale values of Iba1 expression by WB in WT mice are 0.491 ±0.039, 0.657 ± 0.069, 0.930 ±0.046 and 0.926 ±0.046;average optical intensity values of Iba1 expression by IHC in WT mice are 0.412 ±0.122, 0.625 ±0.135, 0.963 ±0.213 and 0.978 ±0.224.The data indica-ted that Iba1 expression increased in SAH KO group in comparison to SAH WT group on 1, 3, 5 day after SAH (P<0.05).Moreover, Nrf2 deficiency promoted the activation and polarization of M /M by increased Iba1 protein expression and CD16/32 +Iba1 +cells after SAH ( P<0.05). Conclusion SAH induces M/M activation and proliferation in mice, and Nrf2 deficiency promotes the activa-tion, proliferation and M1 polarization after SAH .

Objective To study the effect of different dialysis modalities on pruritus in elderly maintenance hemodialysis patients.Methods Totally 51 patients were randomly divided into hemoperfusion combined with hemodialysis group (HD+ HP),hemodiafiltration group (HDF) and hemodialysis group (HD).Plasma β2-microglobulin(β2-MG) and intact parathyroid hormone (iPTH) were measured by means of radio immunoassay at pre and post dialysis,4 weeks and 8 weeks after dialysis,cutaneous pruritus was scored.The remission rate of itching was calculated at 8 weeks after dialysis.The parameters were compared among different groups.Results The level of plasma β2-MG was lower in HD+HP group after dialysis than pre dialysis [(13.48±3.05)mg/L vs.(16.27±4.73) mg/L,t＝2.044,P＜0.05],at 4 weeks and 8 weeks after dialysis,its levels were decreased to (10.97±3.25)mg/L(t＝3.808,P＝0.002)and (6.47±2.35)mg/L(t＝7.650,P＝0.000),respectively.The levels of iPTH were also found decrease from(887.5 ± 242.7)ng/L to (688.3 ±223.4)ng/L(t＝3.384,P＝0.004)at 4 weeks and (467.2±102.5) ng/L(t＝6.578,P＝0.000) at 8weeks after dialysis in HD+HP group (all P＜0.01).There were differences of the levels of plasma β2-MG and iPTH at 4 weeks and 8 weeks after dialysis in HDF group (all P＜ 0.05),but no differences of the levels of plasma β2-MG and iPTH during every period were found in HD group(all P＞0.05).The scores of cutaneous pruritus were decreased from (21.17± 5.01) scores to (13.37±2.85) scores(t＝ 5.580,P＝0.000)at 4 weeks and (8.52±4.38) scores(t＝7.838,P＝0.000)at 8 weeks after dialysis in HD+ HP group,and also the scores at 4 and 8 weeks after dialysis in HDF group (all P＜0.01),but there were no significant differences of the scores during every period in HD group (all P＞0.05).The remission rate of itching was better in HD+ HP group than in HDF group [88.24％ (15/17 cases) vs.58.82％ (10/17 cases),x2＝14.44,P＝0.000],better in HDF group than in HD group 23.53％ (4/17 cases) (x2 ＝4.37,P＝0.037).Conclusions HD+HP is superior to HDF in efficiently clear β2-MG and iPTH,and relief cutaneous pruritus,but HD can poorly clear β2-MG and iPTH or relief itching.
