Objective:To improve the identification and determination methods in the original quality standard for belladonna oral solution.Methods:Belladonna oral solution was identified by a specific chromatogram of HPLC,and scopoletin and hyoscyamine sulfate in belladonna oral solution were detected by dual wavelength spectrophotometry.The detection of fingerprints was performed on a Waters SunFire C18 (250 mm×4.6mm,5 μm) column.The mobile phase was methanol-0.05% phosphoric acid solution at a flow rate of 1.0 ml·min-1.The detection wavelength was 344 nm and the column temperature was 30℃.The detection of scopoletin and hyoscyamine sulfate was performed on the same C18 column.The mobile phase was 10 mmol·L-1 heptanesulfonate sodiumat (pH value was 3.3 adjusted by glacial acetic acid)-absolute ethanol-acetonitrile (68.75∶6.25∶25) at a flow rate of 1.0 ml·min-1.The detection wavelengths were 344 nm and 210 nm,and the column temperature was 30℃.Results:The specific chromatogram of belladonna oral solution was accordance with that of belladonna tincture raw material.The retention time and relative peak area of each characteristic peak and reference peak all met requirements of Chinese Pharmacopoeia.Scopoletin and hyoscyamine sulfate were completely separated from the other compositions under the above mentioned conditions.The calibration curves were linear within the range of 5.168-103.360 μg·ml-1 (r=1.000 0) for scopoletin and 50.560-758.400 μg·ml-1 (r=0.999 9) for hyoscyamine sulfate.The average recovery was 101.79% (RSD=1.05%,n=6) and 100.92% (RSD=0.97%,n=6),respectively.Conclusion:After the quality control method improvement,the identification shows high specificity and the quality of belladonna oral solution can be better controlled by the two selected index components.The method is easy and accurate,which can provide a reliable way to control the quality.

Objective To study the significance and feasibility of modified early warning scores (MEWS) assessing the conditions and death prediction among the pre-hospital acute poisoning patients.Methods We performed a prospective,observational study of the pre-hospital acute poisoning patients between January 1,2010 and December 31,2010.Data was collected to calculate the MEWS.Numeration data was presented in percentage by using chi-square test,and measurement data was expressed in mean with standard deviation,and P ＜ 0.05 was considered to be different with statistical significance.Observation lasted for 90 days after admission to get the results as observation index and ROC was drew and the area under the curve and the predicting index were calculated.The patients without vital signs and unsuccessful resuscitation were not included in this study.Results It showed 287 person times with 0 ～ 6 scores,accounting 94.4％,17 person times with 7-13 scores,accounting 5.59％,among the dead patients,MEWS were more than those of the survival group with statistical significance (P ＜ 0.05).The area under ROC was 0.99 indicating that MEWS≥7 was the board line for severe pre-hospital acute poisoning patients with sensitivity of 91.7％,specificity of 97.9％,accuracy of 97.7％ and Youden of 0.896 for predicting death.It showed high significance of the application of MEWS in assessing acute poisoning patients and death prediction.Conclusions MEWS assess pre-hospital acute poisoning patients and predict death with good resolution and strong application significance,which is simple,practical and applicable.

[Objective]To investigate the relationship of baseline antimullerian hormone(AMH)and live birth rate of IVF/ICSI and further explore the prognostic effect of AMH on live birth rate.[Methods]All non-polycystic ovary patients who underwent their first embryo transfers in our unit and had basal serum AMH evaluated between 2010 and 2015 were evaluated in this retrospective study. Patients were grouped according to their AMH level,i.e. low AMH group with AMH less than 1.1 ng/mL(n = 485),middle AMH group with AMH between 1.1 ng/mL and 7.0 ng/mL (n = 1 989),and high AMH group with AMH higher than 7.0 ng/mL (n=468). For age subgroup analysis,patients were stratified as follow:group A(age≤29 years),group B(30~34 years),group C(35~39 years)and group D(over 40 years). We compared clinical outcomes between AMH groups in different age groups usingunivariate and multivariate analysis. ROC analysis was utilized to assess predictive value of AMH on live birth rate.[Results](1)In both fresh and frozen embryo transfers,baseline AMH was significantly related to clinical outcomes. The lower AMH was,the lower implantation rate,clinical pregnancy rate,and live birth rate. However,higher miscarriage rate was observed. All difference reached statistically significant.(2)In age subgroup analysis,we demonstrated AMH was related to live birth rate in patients in group A,B, and C,regardless of fresh or frozen embryo transferred. In those over 40 years,AMH was related to live birth rate in frozen cycles (P < 0.05)but not fresh cycles(P = 0.092). The further multivariate analysis confirmed the above results after controlling po?tential confounding variables.(3)The AUC of ROC analysis for AMH predicting live birth rate were 0.647,0.633 for fresh and fro?zen cycles respectively.[Conclusion]Baseline AMH as one of excellent ovarian reserve markers ,was significantly related to live birth rate in fresh or frozen cycles. Baseline AMH was an independent prognostic factor of live birth rate,but its predictive value on live birth rate was of limited clinical value.

Objective To explore the sensitivity of a little amount of subarachnoid hemorrhage (SAH) between CT and different MR sequences through animal experiment,to find a more sensitive way to diagnosis SAH.Methods 18 healthy adult white New Zealand rabbits were randomly divided into two experimental groups(group A and group B) and one control group(group C).Rabbit SAH model was established by injecting blood into the cisterna magna one time.All rabbits underwent CT and MR scan at 2 hours,48 hours after operation.The findings on CT and different MR sequences were observed and recorded.Results ①In experimental groups(group A and group B),MR FLAIR sequences in the diagnosis of a little amount of SAH was more sensitive than that on MR T1WI,T2WI and CT in acute phase.And the diagnosis sensitivity between MR FLAIR and CT was statistically significant(P<0.05).②Abnormal signs of SAH could not be found in group C.Conclusion ①Rabbit SAH model was established successfully which will be the foundation for the follow-up study of medical imaging.②MR FLAIR sequence is more sensitive to diagnose a little amount of SAH in acute phase,and may be used in the routine diagnosis of SAH in acute phase.

Objective To observe the effect of Wenxiao Decoction in treating the patients with carotid atherosclerostic (CAS) plaque and assess the safety. Methods Sixty patients with CAS plaque were randomly allocated to treatment group (33 cases) and control group (27 cases). The control group was given routine therapy, and the treatment group was given Wenxiao Decoction additionally. And they were further divided into half-year treatment group and half-year control group, 1-year treatment group and 1-year control group. Carotid artery color Doppler ultrasound and hepatorenal function were examined before and after treatment. Results Compared with the control groups after therapy, the average numbers of plaques, maximal plaque thickness, Crouse plaque integral were decreased both in 1-year and half-year treatment groups (P<0.05, P<0.01). The plaque stability of 1-year treatment group was better than that of half-year treatment group. The average numbers of plaques, plaques size and Crouse plaque integral increased in control groups after routine therapy (P<0.05, P<0.01). Bilateral common carotid artery diameter, intima-medial thickness (IMT) and hepatorenal function had no statistical difference between before and after treatment both in treatment and control groups (P>0.05). Conclusion Wenxiao Decoction is effective and safe in treatment of CAS plaque, and plaque stability is more obvious with the extension of treatment time.

AIM: To investigate the frequency and pattern of deletion of p53 gene in primary hepatocellular carcinoma (HCC) and its clinical significance. METHODS: The interphase dual fluorescence in situ hybridization(FISH) technique was applied to detect loss of p53 gene in HCCs. RESULTS: The deletion of p53 gene was found in 68.0% of HCCs whereas no loss of p53 gene was detected in 40 mated normal liver specimens. Loss of p53 gene was closely related to tumor size and serum ?-fetoprotein(AFP) level in HCC patients ( P 0.05). The 2-year survival rate of postoperative HCC patients was significantly lower in the HCC cases with p53 gene deletion (25.6%) than those without p53 gene loss (69.6%) ( ? 2=11.463, P
