Objective To explore the best plan of perioperative individualized fluid therapy in the elderly patients with coronary heart disease undergoing gastrointestinal surgery.Methods Eighty elderly patients with coronary heart disease undergoing gastrointestinal surgery were divided into experimental group and control group by random digits table method with 40 cases each.Conventional capcity treatment was given during surgery and postoperative period in control group.Individualized fluid therapy was used during surgery and postoperative period in intensive care unit of 24 h in experimental group,which was determined based on target controlled fluid therapy according to the cardiac index,stroke volume,and stroke volume variation.Traditional fluid therapy was used in control group in the intraoperative and postoperative period.The two groups were compared in terms of postoperative hemodynamic parameters,total fluid volume,incidence of adverse cardiac events,and recovery of gastrointestinal function.Results The mean arterial pressure at the beginning of the operation,the cardiac index at operation begining 1 h and at the end of operation were (80.4 ± 6.4) mmHg (1 mmHg =0.133 kPa),(4.0 ± 0.6) L/(min ·m2),(4.1 ± 0.8) L/(min ·m2) in experimental group and (76.9 ± 8.0) mmHg,(3.5 ± 0.4) L/(min· m2),(3.6 ± 0.3) L/(min · mè) in control group,and there were significant differences between two groups (P ＜ 0.05).During surgery and 24±hour stay in intensive care unit,the total fluid volume,crystal usage,urine and colloid usage were (2 915 ± 650),(2 715 ± 415),(1 515 ± 315),(1 225 ± 385),(419 ± 233),(619 ± 285),(1 015 ± 220),(1 535 ± 455) ml in experimental group and (3 645 ±770),(3 355 ±750),(2 315 ±320),(1 855 ±325),(602 ±31),(875 ±423),(805 ±250),(1 135 ± 205) ml in control group,and there were significant differences between two groups (P ＜ 0.05).The perioperative adverse cardiac events rate was 30％ (12/40) in experimental group,lower than 45％ (18/40) in control group,but the difference was no statistically significance (P ＞ 0.05).Conclusion In the elderly patients with coronary artery disease undergoing gastrointestinal surgery,individualized fluid therapy can effectively decrease adverse cardiac events,improve postoperative gastrointestinal function,and reduce length of hospital stay.

According to the large-scale investigation on the positive rates of serum HBV markers in hospital population, the HBV infection rate in Chinese population went down gradually and the infection rate of HBV was markedly lower in the low age people. Applying epidemiological principle to design,technology standardization,multiple-center survey were the premise of reliable data on HBV infection rate in hospital population, which could be used as important basis of decision making on prevention and control.

Statement of the importance of the basic legal principles for both the law and law operation,demarcation of the scope of the basic principles for the general health law,and establishment of the legal interests under its protection.The paper proposes that the cornerstones of the general health law should observe the three basic principles of protection of citizens' healthy life,improvement of health conditions,and safeguard public health and safety,with the three clearly stipulated in the law.

Hepatitis B virus has a high degree of genetic variation. Multiple selection pressure,exerted by vaccine,antiviral drugs and diagnostic reagents,might favor certain mutations of HBV. HBV variation under the selective pressure may affect the pathogenesis of HBV-related liver disease,immunization effect,antiviral efficacy and laboratory tests.In this paper,we summarize the molecular characteristics and its significance of HBV variants,which will help us to manage hepatitis B.

HBV infection is the key factor that causes liver inflammation,liver injury and immune dysfunction.Chronic hepatitis caused by HBV,a non-cytotoxic virus,is a kind of immune injury induced by liver cells that clear virus infection in immune system.Effector T lymphocyte plays a central role in immune system to clear HBV in liver cells,and the outcome of HBV infection is directly influenced by its functions and quantity.After antiviral therapy for patients with sustained HBV infection,whether to restore and rebuild immune function is critical in achieving ideal end point of treatment.Technologies,mainly including stimulation and culture of HBV antigen,flow cytometry,enzyme-linked immunoassay to detect cytokines,etc,are used in detection of HBV-specific T lymphocytes.

Objective HPLC was used to establish a method for determination of rutin in herba crisii. Methods Lichrospher C18 column(4.6 mm?200 mm,5?m)was used with methoanol-acetic acid(35∶65) as mobile phase,flow rate being 1.0 mL/min,column temperature at 30℃,detection wavelength at 254 nm.Results The content of rutin in herba crisii was 0.5808 mg/g.Conclusions The method is proved to be simple,rapid,and accurate.It can be applied to content determination of rutin in herba crisii.

Objective:To investigate the effect of PHB/PEO polymer combined with nerve growth factor in the peripheral nerve injury.Method:The male SD rats were treated with autogentic neural transplantation,xenogenic neural transplantation under the immunosuppression,transplantation of PHB/PEO polymer combined with nerve growth factor and PHB/PEO guidance transplantation,respectively.The nerve function and the nerve anatomic structure were evaluated by the sciatic function index(SFI),nerval electrophysiology test,nerve fiber number and electron microscope.Result:The SFI,nerve conduction velocity,nerve fiber number and the regeneration of nerve fiber and myeline sheath of the PHB/PEO polymer combined with nerve growth factor group is similar to the autogentic neural transplantation group,and is better than the xenogenic neural transplantation group and PHB/PEO guidance group significantly.Conclusion:The effect of PHB/PEO polymer combined with nerve growth factor is similar to the autogentic neural transplantation,and is better than the xenogenic neural transplantation and PHB/PEO guidance significantly in the repair of sciatic nerve injury.
