Sepsis is a common desease with a high mortality in pediatric intensive care unit. The patho-genesis of sepsis remains unclear. Recent studies have found that extracellular histones play an important role in the incidence of sepsis. This review provides new ideas for the diagnosis and treatment of sepsis.

Stem cells possess unlimited self-renewal properties and the ability to produce multiple differentiation progenitors. Mesenchymal stem cells (MSCs) can specifically migrate to multiple kinds of tumors and their metastases in a systemic manner(to all parts of the body). Therefore genetically modified MSCs can serve as vehicle of anticancer factors to inhibit growth of tumor. But many questions remain to be answered and the precise mechanisms remain unclear. This paper reviews the mechanism of MSC homing, MSCs as delivery vectors for cancer therapy and its advantages over traditional drug vehicle. MSCs as delivery vectors can be used for cellular therapy in future cancer treatment.

To study the effect of different storage conditions and storage time on herb quality of Lonicera macranthoides, different packaging materials including vacuum plastic bags, plastic bags, woven bags, sealed with endometrial bags, paper bags, sack bags were selected for the study under different storage conditions including room temperature, 5 degrees C refrigerator, low temperature of - 20 degrees C refrigerator and desiccator. Twenty-four batches of samples were used for the study, and active ingredients were determined. The experimental results showed that the ingredients in each storage group changed with the storage time, storage conditions (storage environment, packaging). Under the same storage time, the storage environment (temperature, humidity) had effect on the stability of herb quality. Low temperature had less effect on herb quality. The effect of packaging on herb quality was as following: plastic vacuum packaging > woven with endometrial sealed packaging > plastic bag > woven bag > sack bags > paper bags. Under the same storage conditions, with the increase of storage time, caffeic acid content increased slowly, and other five ingredients content decreased gradually. Storage time affected significantly on the intrinsic quality (chemical composition) and appearance of herb. It is suggested that low temperature (5 degrees C), dark and sealed storage are suitable for storage of L. macranthoides herb, the storage time should be not more than 24 months.

Objective To study the effects of tetrahydroxy stilbene glucoside(TSG)on H2O2‐induced apoptosis of human umbilical vein endothelial cells (HUVECs)and on the expressions of X‐linked inhibitor of apoptosis protein (XIAP)and p53.Methods HUVECs were cultured in vitro and divided into 6 groups:control group ,300 μmol/L H2O2 group ,1 μmol/L TSG+ 300 μmol/L H2O2 group ,10 μmol/L TSG+300 μmol/L H2O2 group ,100 μmol/L TSG+ 300 μmol/L H2O2 group ,30μmol/L Embelin+ 10 μmol/L TSG+ 300 μmol/L H2O2 group.The morphology of apoptotic cells was observed by Hoechst 33258 staining.The mRNA and protein expressions of XIAP ,p53 ,Caspase‐3 were detected by RT‐PCR and Western blotting , respectively.Results The number of apoptotic cells and the expression level of p53 were significantly increased while the ex‐pression level of XIAP was dramatically decreased in H2O2 group as compared with control group.The expression level of p53 and the number of apoptotic cells were down‐regulated while the expression level of XIAP was up‐regulated after treatment with 10 or 100 μmol/L TSG when compared with H2O2group.Moreover ,compared with those in 10 μmol/L TSGgroup ,the number of apoptotic cells and the expression of Caspase‐3 were significantly enhanced after pretreatment with 30 μmol/L Embelin for 6 h.Conclusion TSG can inhibit H2O2‐induced apoptosis of HUVECs by down‐regulating the expression level of p53 and up‐reg‐ulating the expression level of XIAP.

Objective To explore the effects of different processes on the contents of three alkaloid ingredients in Coridalis Rhizoma.Methods The contents of three alkaloid ingredients (protopine, dehydrocorydaline, tetrahydropalmatine) were determined by HPLC. Agilent HC-C18(2) column (4.6 mm × 250 mm, 5μm) was set at 35℃; acetonitrile-0.1% phosphoric acid solution (triethylamine adjusted pH 5.3) (26:74) was set as mobile phase; the flow rate was 1.0 mL/min and detection wavelength was set at 280 nm; the injection volume was 10μL. The three components were separated well under these chromatographic conditions. The linear relationship between the mass of each component and the peak area was good (r2≥0.9996). The average recoveries were 100.31%, 99.34%, and 99.34%, respectively (RSD≤2.70%).Results The contents of protopine, dehydrocorydaline, tetrahydropalmatine and the total contents of three alkaloids were higher than other groups in large size samples (diameter of fresh products was 2.0–3.0 cm) which were boiled 5–6 minutes, the medium size samples (diameter of fresh products was 1.5–1.9 cm) which were boiled 2–4 minutes and the small size samples (diameter of fresh products was 0.7–1.4 cm) which were boiled 1–2 minutes. The contents of alkaloid in boiled process were lower than steamed process.Conclusion The Results of study provide an experimental basis for origin processing of Coridalis Rhizoma.

Objective To study the effect of morphine used in epidural anesthesia on puerpera after cesarean section and the safety of morphine to neonate. Method One hundred puerpera undergone cesarean section were randomly divided into test group and control group with continuous 2% lidocaine epidural anesthesia, as soon as the operation were finished, 2 mg morphine was injected into vacum epidurale for test group, nothing for control group. Colostrum and plasma, urine samples of puerpera and neonate were collected, morphine and metabolite level were tested by GC-MS and FPIA. Result Morphine concentrations ranged from 0.05). Conclusion As the epidural analgesia medicine after cesarean section, morphine has no side-effect to neonate and is safe to neonate.

ObjectiveTo study the mechanism of hyperbaric oxygen (HBO) on treatment of the late-onset fetal growth restriction (FGR). MethodsSixty-one pregnant women, who were first diagnosed as FGR after 32 weeks, were voluntarily devided into group-A (Routine management, n=28) an d group-B (HBO combined with routine management, n=33). Thirty cases of normal pregnant women were served as control group, called group-C (n=30).Results(1)Before treatment, the values of umbilical artery systolic/diastolic Ratio (S/D), pulse index (PI), resistant index (RI) and the blood viscosity at the low shear rate (LBV) of both group-A and group-B were significantly higher than those of group-C, P

Objective: To improve the treatment order and improve the work efficiency of the doctors, our hospital has run the triage calling system in out-patient department. Methods:Using VC++ language and the middleware technology, we realize the function of voice calls, large screen display control, background management and data synchronization. HIS system realizes the automatic call patient registration by transfer the registration information to the triage system. Results: The trial operation of outpatient triage calling system in our hospital has completely changed the previous traditional triage mode of“nurse as orientation”. The system reduces not only the work pressure of health care, but also significantly improve the doctors' work efficiency and service quality. Conclusion:Guide triage system can effectively improve the environment and outpatient treatment order, greatly enhance the patient’s satisfaction.
