Aim To study the inhibitory effect of Oxymatrine-Baicailin compound on the secretion of hepatitis B viral antigens in HepG 2.2.2.15 cells.Methods HepG2.2.2.15 cells were cultured and treated with a series of Oxymatrine,Baicailin,or Oxymatrine-Baicailin compound respectively.The toxicity effect was determined by MTT colorimetry.Con-tents of the hepatitis surface antigen(HBsAg) and hepatitis e antigen(HBeAg) in the culture supernatants were determined by Enzyme linked immunosorbent assay.Results Oxymatrine at concentrations between 0.125 and 1 g?L~(-1) had little toxicity effect on cells,but Oxymatrine at 2 g?L~(-1) and 4 g?L~(-1) had much more toxicity effect on cells.The inhibitory effect of Oxymatrine on HBsAg and HBeAg increased in a dose-dependent manner from 0.125 to 1 g?L~(-1).The toxicity of Baicailin on cells increased from 0.625 to 2 g?L~(-1),especially when the dose surpassed 1 g?L~(-1).The inhibitory effect of Baicailin on HBsAg and HBeAg increased in a dose-dependent manner from 0.125 to 1 g?L~(-1),but its efficacy was inferior to Oxymatrine's efficacy.Oxymatrine-Baicailin compound had good inhibitory effect on hepatitis B viral antigens secretion,and the inhibition effect of the compound on HBeAg was superior to the effect on HBsAg.The Group C Oxymatrine-Baicailin compound had good synergism inhibition effect on hepatitis B viral antigens secretion and the inhibition rate of the specific group compound was significantly superior to that of Oxymatrine treatment alone(HBsAg:P=0.043;HBeAg: P=0.026).Conclusion Oxymatrine-Baicailin compound has good synergism effect on hepatitis B viral antigens secretion in HepG2.2.2.15 cells.

ObjectiveTo study the relation of phonation and respiration in normal subjects. MethodsUsing Aerophone Ⅱ Model 6800 and Visipitch 6097, vital capacity was recorded first , then the simultaneous phonation volume, maximum sustain phonation time,mean airflow rate,sound pressure level and average pitch were recorded in order to induce the relation of phonation and respiration in normal subjects. ResultsThere was a linear correlation between phonation volume and vital capacity. Maximum sustain phonation time varied with changes of mean airflow rate and phonation volume and mean airflow rate varied little in different subjects and had no relation with average pitch and sound intensity. ConclusionMaximum phonation time, the mean airflow rate and ratio of phonation volume to vital capacity can be used as indicator in clinical application.

AlM:To analyze and explore the clinical efficacy of strengthening lateral tarsal strip and advancing lower eyelid retractor for the treatment of degenerative entropion with eyelid relaxation
METHODS: Reviewed from January 2011 to January 2013, 21 cases (33 eyes) of degenerative entropion eyelid relaxation were treated with operation of strengthening lateral tarsal strip and advancing lower eyelid retractor ( fornix conjunctival incision ) , the follow-up was 12-24mo, curative effect was observed.
RESULTS: All the patients were cured completely, have no recurrence or overcorrection phenomenon. The cure rate of operation was 100%, there was no complication.
CONCLUSlON: Operation of strengthening lateral tarsal strip and advancing lower eyelid retractor is a safe, reliable, efficient operation to the treatment of degenerative entropion with mode of eyelid relaxation.

Some of the SARS patients' rights( such as self-determination, privacy, personal freedom and body eminent domain) and social commonweal principle conflict, which restricts a SARS patient's rights. Meanwhile the SARS patients must carry out their obligations to safeguard public interests. It's revealed from one aspect that the public not only pay attention to the patients' legal rights and interests but also understand the patients' rights and obligations are relative and flexible.

The activity of the negative regulator of cell cycle, P27, affects the normal process of cell cycle. As a type of cell cycle diseases, tumor is closely correlated with the activation of P27. It is shown that the level of P27 decreases in most kinds of tumors.By its influence on cell proliferation and apoptosis, P27 plays an important role in the occurrence and development of tumor. The activity of P27 is regulated by several pathways either at or after transcription, so various ideals which directly change the protein level of P27 or indirectly interfere the activities of elements in regulative pathways of P27 will provide many novel and efficient ways for therapies in tumors.

Objective To investigate the effect of goal-directed fluid treatment (GDT) on prognosis during emergency operation for craniocerebral trauma patients.Methods Thirty craniocerebral trauma patients treated with emergency craniotomy from January 2015 to October 2015 were divided into control group (n =15) and GDT group (n =15),according to the random number table.In control group,the patients [ten males and five females,age of (40.3 ± 12.1) years and weighting (62.1 ± 9.1) kg] were given conventional fluid therapy based on the intraoperative mean arterial pressure,heart rate,central venous pressure,etc.In GDT group,the patients [eleven males and four females,age of (44.5 ± 9.6) years and weighting (64.0 ± 6.9) kg] received GDT based on the stroke volume variation (SVV) under Vigileo monitor.Serum levels of neuronspecific enolase (NSE) and S100-β were respectively detected by electrochemical luminescence and ELISA method before anesthesia induction (T1),1 h after dura incision(T2),immediately after surgery (T3),6 h after operation(T4),24 h after operation(T5) and 48 h after operation (T6).Intracranial pressure and cerebral perfusion pressure (CPP) were detected at all time points,and Glasgow Coma Score (GCS) at T1,T5 and T6.Postoperative infection,brain edema,hospital stay in ICU,total hospital stay and death rate were recorded.Results Compared with control group,levels of NSE in GDT group were decreased at T4,T5 and T6 and levels of S100-β in GDT group were decreased at T3,T4,T5 and T6 (all P ＜ 0.05).Intracranial pressure in GDT group was not significantly different from that in control group (P ＞ 0.05).GCS at T6 was higher in GDT group than that in control group (P ＜ 0.05).Length of ICU stay and length of total hospital stay in GDI group were (4.5 ± 2.1) d and (14.3 ± 3.6) d respectively,shorter than (6.3 ± 1.9) d and (18.3 ± 4.0) d in control group (P ＜ 0.05).None experienced infection,brain edema and death after operation.Conclusion Compared with conventional fluid therapy,GDT is beneficial to the prognosis of craniocerebral trauma patients undergoing emergency craniotomy without increasing intracranial pressure and brain edema,and GDT can reduce hospital stay.

AIM: To investigate the adsorption mechanism of pueraria on the molecular imprinting polywer(MIP) and Scatchard analysis was carried out. METHODS: Pueraria MIP was synthesized using pueraria as the template,acrylamide as the functional monomer and ethylene glycol dimethaerylate(EDMA) as the crosslinker. RESULTS: The result showed that at least two classes of binding sites were formed in the imprinted polymer.Extracting compounds from Radix Pueraria was separated by MIP. CONCLUSION: The component of the products is analyzed by HPLC.The result shows that the final products contain pueraria and the other two kinds of isoflavone.
