Ginsenoside is the main component of antitumor effects of traditional Chinese medicine (TCM) Ginseng. Clinical pharmacological studies have shown that Ginsenoside Rb1 can inhibit P-gp which can lead to efflux of drugs, enhance the sensitivity of cells to drugs, reduce the multidrug resistance of the tumor cell, and maintain the immune function of the body to tumor cells. Ginsenoside Rg3 can impact tumor cell protein expression, play a role in cell division, induce tumor cell apoptosis and inhibit tumor growth of blood vessels. Ginsenoside Rh2 may play an antitumor effect by inhibiting tumor cell proliferation and metastasis, inducing tumor cell apoptosis. This article ex-plained the antitumor effects and mechanism of Ginsenoside Rb1, Rg3, Rh2 in order to provide theoretical evidences for the clinical development and application.

Objective To discuss the application value of multi- position radiography in the diagnosis for fracture of rib.Methods 98 cases with integrated data of thoracic trauma undergone multi- position view X-ray from 2007 to 2009 were retrospectively reviewed.Results The percent of fractures with orthophoria view is 65.4%.The percents of fractures with oblique position,tangential projection and spot film under the X-ray fluoroscopy are 20.6%、5.1% 、8.8%,while doesn' t find the A-P position,The total percent is 34.6%.Conclusion Multi-position radiography can elevate the diagnosis for fracture of rib and has application value.

Objective To discuss the feasibility of application of laryngeal mask airway(LMA)in pediatric corrective surgery of lingual frenum. Methods Retrospective study was conducted of 42 chil-dren using laryngeal mask airway in selective surgical correction of lingual frenum under general anesthe-sia in our hospital. The childrenˊs vital signs were recorded at five different time points:baseline before an-esthesia(T0),consciousness and eyelid reflex disappear just after anesthesia induction(T1),time right af-ter the LMA insertion(T2),3 ~ 5 min after beginning of operation(T3),and time at the extubation(T4). The success rate of first LMA insertion and the number of changing to other ventilation way were recorded. The shift of LMA and postoperative sore throat within 24h were recorded. Results The success rate of the first LMA insertion was 85. 71% . Intraoperative laryngeal mask airway leak and shift did not occur and the ventilation was also good. Vital signs of the children were stable during operation. The incidence of postop-erative sore throat was 15% within 24h. As to the heart rate,the vital signs of baseline T0 were significant-ly different from other time points(T1,T2,T3,T4). After the anesthesia,there were no significant differ-ences in heart rate among different time points(T1,T2,T3,T4). Compare with T2 and T3,the values of partial end expiratory pressure of CO2 at T0,T1,and T4 were significantly different. Compare with T0,the values of mean arterial pressure at T1,T2 and T3 were significantly different,but there was a significant difference in mean arterial pressure between T1 and T4. As to the pulse oxygen saturation,all the values were above 95% . Conclusion Laryngeal mask airway is a supraglottic airway management method. The advantages of fewer haemodynamic changes and postoperative complication are confirmed. It is feasible and safe for securing the airway in surgical correction of lingual frenum.

Objective:To observe the effect of the signaling pathway of protein kinase C (PKC)-nuclear factor-erythroid 2-related factor 2 (Nrf2) on the expression of heme oxygenase -1 (HO-1) induced by cigarette smoke extract in rat airway epithelial cells.Methods:The airway epithelial cells of 25 male SD rats were randomly divided into a control group, a CSE3h group, a RO318220 group (PKC inhibitor), a Nrf2 siRNA group and a Nrf2 siRNA+RO318220 group, 5 rats in each group. hTe control group was incubated with DMEM/F12 alone. hTe CSE3h group was treated with 10% CSE for 3 h. hTe RO318220 group was pretreated with 3 μmol/L RO318220 for 0.5 h and subsequently treated with 10% CSE for 3 h. hTe Nrf2 siRNA group was pretreated with Nrf2 siRNA, and then treated with 10% CSE for 3 h. hTe Nrf2 siRNA+RO318220 group was pretreated with Nrf2 siRNA and 3 μmol/L RO318220 for 0.5 h, and then treated with 10% CSE for 3 h. hTe protein levels of Nrf2 in the nucleus and cytoplasm, and HO-1 and PKC in the whole cells were semi-quantified by Western blot. The protein expression of HO-1 was measured by immunocytochemistry. HO-1 mRNA expression was detected by RT-PCR. Immunolfuorescence staining was used to observe the nuclear translocatin of Nrf2. Results: CSE markedly induced Nrf2 nuclear translocation in the rat airway epithelial cells, and RO318220 pretreatment blocked the CSE induced Nrf2 nuclear translocation. Immunocytochemistry showed that HO-1 protein expression was strongly positive in the CSE3h group, weakly positive in the other 4 groups. hTe expression of PKC protein, HO-1 mRNA and protein signiifcantly increased in the CSE3h group, and HO-1 activity markedly improved in the CSE group (P<0.05). hTe level of PKC protein expression was not signiifcantly different in the Nrf2 siRNA group compared with that in the CSE3h group (P>0.05). Conclusion: CSE induces the nuclear translocation of Nrf2 by PKC signaling pathway, thus upregulating the HO-1 expression in the rat airway epithelial cells.

Molecular biomarkers could change associated with disease processes.So,the detection of metabolic markers becomes the key to early diagnosis,treatment and prognosis evaluation disease.But the detection of abundant metabolites in body becomes a crux of laboratory medicine at the same time.The recent advances in nuclear magnetic resonance (NMR) spectroscopy reveal the unequivocal value of NMR in metabolomics platforms.NMR spectroscopy has inherently distinct capabilities to identify and quantitatively measure a large amount of low concentration metabolites in a non-destructive manner.The implementation of NMR technology into a multidisciplinary approach to biomarker identification will improve the auxiliary diagnostic ability of laboratory medicine for the disease.

The pre-examination process is the first key step in the total testing process of clinical laboratories.Specimen acceptability is an important indicator to measure the quality of pre-examination.In order to identify the risks and the root causes in the process , establishment and monitoring of quality indicators about specimen will effectively control the risks , enhance the acceptability of specimens , promote the improvement of pre-examination quality and finally get the aim of assuring patients′safety.

With the obesity epidemic,children and adolescents with type 2 diabetes mellitus(T2DM)signifi-cantly increased throughout the world,screening and diagnosis of T2DM in the high - risk population is very important. In addition to lifestyle modification,the recommended optimal pharmacologic treatment of children and adolescents with T2DM is Metformin and Insulin. To reduce the risk of cardiovascular diseases,should fully understand the comorbidities and complications of T2DM,and take better assessment and management.

Objective To investigate the effect of povidone iodine irrigation combined with levofloxacin eye drops on the inflammatory indexes, NO and antioxidant indices in serum and tear fluid of patients with diabetic cataract.Methods 50 cases of pati ents with diabetic cataract and admitted into the hospital during January 2013 to January 2015 were selected as the research objects all of whom received cataract surgery.According to the randomized double blind method, the patients were divided into two groups with 20 cases in each group.The control group received levofloxacin eye drops intervention before surgery while the observation group were treated withpovidone iodine irrigation, based on the control group.The inflammatory indexes (IL-2, sIL-2R, IL-6), NO, antioxidant indexes (TAC, SOD, CAT) and condition of postoperative infection were compared between the two groups before and after irrigation.ResuIts In the observation group, the sIL-2R, IL-6 and NO levels in serum and tear fluid after irrigation were significantly lower than those in the control group while IL-2, TAC, SOD and CAT were significantly higher than those in the control group.The differences were statistically significant (P<0.05).The postoperative infection rate of the observation group was 0.0% which was significantly lower than 16.0% of the control group.The difference was statistically significant ( P<0.05 ) .ConcIusion Povidone iodine irrigation combined with levofloxacin eye drops can significantly reduce the inflammatory reactions in patients with diabetic cataract and improve their antioxidant level.
