Objective To observe the clinical significance and laboratory diagnostic values of Pre-S1 antigens (Pre-S1)and its relativity to HBeAg and HBV-DNA after using interferon in association with kurarinone.Methods The content of Pre-S1 and HBV-M was detected by ELISA and the levels of HBV-DNA were detected by flores- cence quantitative PCR(FQ-PCR)in 100 serum samples of patients with HBV infection and patients after an antivi- ral treatment.Results Matched control in 50 serum of HBsAg-positive and detectable HBV-DNA cases,both 29 samples in 30 HBeAg-positive cases and 17 samples in 20 HBeAg-negative cases Pre-S1s were positive.Treatment set 50 serum of patients after taking two courses of an antiviral treatment for HBV infection,drawing blood to observe related markers,5 cases of effect set were turned into negative for serologic markers and virologic markers.19 cases of valid set,serologic markers were various and the HBV-DNA copies descended 2-3 orders of magnitude.26 cases of invalid set,serologic markers were not various,and 30 % samples of the HBV-DNA copies descended 1～2 orders of magnitude.Conclusion It was supplementary for Pre-S1 to indicate HBV expression when the HBeAg varied.It also provided detcctable laboratory markers in HBV infectivity,replication and therapeutic efficiency evaluation.

Volatile oil components and the contents and types of amino acid in spica of Prunella vulgaris were analysed by GC-MS and amino acid analyzer. Esters, fatty acids, aromatic hydrocarbon, ketone and several alcohol compounds were identified by mass spectrum comparison. In these ingredients, beta-ionone smelled aroma of cedar, raspberry, nerolidol showed weak sweet soft orange blossom flavor, neroli tasted sweet and fresh, nerolidol tasted sweet with light aroma of wood, hexadecanal showed a weak aroma of flowers and wax, alpha-sinensal had rich and fresh sweet orange flavor. To some extent, these types of aromatic substances can affect the taste of herbal tea or decoction made of Spica Prunellae. Among amino acids detected, natural amino acids accounted for a larger proportion, and those natural amino acids showed bitterness, slight bitterness, sourness (freshness), sweetness, slight sweetness, sourness (slight freshness). The results indicated that bitter and slightly bitter amino acids have the greatest impacts on the sense of Spica Prunellae.

Induced the mouse embryonic stem(ES)cells into neural cells on silk fibroin via the improved 4-/4+ RA method to explore the effect of the silk fibroin to the ES-derived neurons' growth,adherence and differentiation.Suspended the ES cells into EBs and then transferred them to three different substrates-coated 35 mm dishes including gelatin,Bombyx mori silk fibroin(SF) and Tussah silk fibroin(TSF) to identify the adherence and proportion of ES cells-derived neurons under these three substrates.The results showed that the EBs adhered to the gelatin and TSF are faster than to the SF.The average adhesive rate on gelatin and TSF are 90.3% and 84.4% respectively,and only 38.5% on SF,all the proportion of ?-Ⅲ-Tubulin positive cells is approximately 40%.It may provide important experimental information for tissue engineering,in which ES cells-derived neuron cells and silk fibroin materials are scaffolds,and also offer a source for cell therapy research of neurodegenerative disease.

Objective To establish the ischemic precondition ([PC) model of PC12 cell line in vitro, and to explore the effect of nitric oxide (NO) on the IPC cerebral protection. Method PC12 cells were cultured and used for producing the model of ischemie precondition by the way of oxygen-glucose deprivation. Twenty dishes of cells were randomly divided into four groups (5 dishes for each group): control group, ischemic precondition group (IPC),non-ischemic precondition group (NIPC) and L-NAME treatment group (L-NAME). In control group, the cells were in-cubated with low glucose (<1 g/L) and2% FBS medium in normal oxygen; in IPC group, the cells were administrated with oxygen-glucose deprivation (OGD) for 6 hours, and then subjected with reperfuaion before OGD 15 hours; in NIPC group, the cells were treated the same as control group for 6 hours, and then subjected with reperfusion before OGD 15 hours; in L-NAME group, the cells received L-NAME (1 mmol/L) and cocultured for 30 minutes before OGD 6 hours, and then received the same treatment as the IPC group. To test whether the model was established, metabolic rate of MIT, LDH release were measured and the apoptosis rate was detected by flow cytometry following oxygen-glucose deprivation 15 hours. The activity of nitric oxide synthases (NOS) was as-sessed by biochemical assay. One-way ANOVA and LSD multiple comparison test were used to analyze differences among different groups, and P<0.05 was considered different. Results Compared with NIPC group, the metabolic rate of MTT increased (94.9%±35.1%, P<0.05), while LDH release and the cell apoptotic rate decreased significantly in IPC group (279.1%±28.1%, P<0.03). Compared with control group(100.0%± 13.5%),the activities of NOS increased both in NIPC and IPC groups (390.0%±14.6%, P<0.01;126.3% ±10.6%, P<0.01). Moreover, the apoptosis rates in each group (control group, IPC group, NIPC group and L-NAME group) were 5.90, 8.73, 38.62 and 11.73%,respectively. Conclusions IPC reduces the death and apoptosis rate of PC12 cell after oxygen-glucose deprivation injury. NO might be involved, but it is not the only factor.

Objective To investigated the serum level of carcinoma antigen 125 (CA-125) and its clinical significance in patients with Budd-Chiari syndrome.Methods We reviewed medical records and laboratory tests of patients with BCS first diagnosed in our hospital between August 2011 and April 2013.235 patients were included as experiment group,while 120 healthy adult volunteers were randomly selected as control group.The serum level of CA-125 were detected by electrochemilumescence immunization assay in this single-center retrospective control study.Results The average serum level of CA-125 in experiment group is higher than that of control group [(147.9 ±246.6) kU/L vs (16.0 ±7.2) kU/L,P ＜0.001].In experiment group,the relative coefficient for serum CA-125 with ascites,alanine aminotransferase,aspartate aminotransferase,albumin and Rotterdam BCS scores was 0.79,0.45,0.29,-0.393 and 0.71,respec tively,P ＜0.001.As of October 2013,we found that the 68 BCS patients with serum CA-125 level 5-fold higher than the upper limit of normal (＞ 175 kU/L) presented much lower survival rates and asymptomatic survival rates than the rest 167 BCS patients after intervention therapy:(95.6％ and 79.8％) vs (98.8％ and 92.0％),P ＜ 0.05.Conclusions The serum level of CA-125 in BCS patients have positive correlation with ascites volume,liver injury degree and Rotterdam BCS scores.Serum CA-125 evaluation appears to be a valuable examination option in BCS as CA-125 levels negatively correlate with worse prognosis,thus could be applied as an efficient tool for prognostication.
