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.

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.

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 study the expressive levels of KAI-1mRNA,Kiss-1mRNA and MTA1 in the benign and malignant lesions of breast,and their clinicopathological significance.Methods We detected the expression levels of KAI-1mRNA,Kiss-1mRNA and MTA1 in the sections from 60 cases of breast cancer and 30 cases of benign lesions of breast.Results The positive rates and scores of KAI-1mRNA and Kiss-1mRNA were significantly lower in breast cancer than those in benign lesions(P

Objective To induce experimental autoimmune myasthenia gravis (EAMG) rabbits by using T?125～147 Methods Peptides T?125～147 were synthesized referring to the residue sequence of acetylcholine receptor of Torpedo California and the rabbits were inoculated with the peptides Clinical manifestation was graded in 4 levels Electrophysiological function was assessed by repetitive nerve stimulation (RNS) and single fibre electromyography (SFEMG) tests Anti peptides antibodies were evaluated by enzyme linked immunosorbent assay (ELISA) Student t test was used to analyze the difference between the EAMG and healthy rabbits Results Following the second inoculation,the rabbits appeared weakness Clinical symptoms were improved by neostigmine At 3,5 and 10 Hz,the decrement of compound muscle action potential (CMAP) and the mean jitter (MCD) of the immunized rabbits were higher than in the healthy ones The percentage of decrement of CMAP in order of the control group and the T?125～147 group were:3 Hz: 1 625?1 317,25 375?7 945; 5 Hz: 2 000?1 732,25 625?9 102; 10 Hz: 1 750?1 392,28 875?8 709.Following the above sequence,the MCD were:3 Hz: (9 875?1 126) ?s,(25 875?7 945) ?s; 5 Hz: (11 375?0 916) ?s,(27 500?3 381) ?s; 10 Hz: (12 375?1 061) ?s,(31 000?4 811) ?s Anti peptide antibodies in immunized groups were significantly higher than those in the control group Conclusion T?125～147 might be served as the immunogenic to induce EAMG in rabbits,accompanied by elevation of anti peptide antibodies and the blockage of neuromuscular transmission
