Point-of-care testing (POCT) of blood glucose has been widely used for continuous monitoring of glucose in clinic due to high sensitivity, convenience, accessibility and shorter TAT.It has been developed rapidly in recent years. But glucose POCT is often out of control and management from central laboratory and usually it was performed by non-laboratorians.It becomes the growing concerns that how to avoid the discrepancy between POCT results and central laboratory results, how to ensure POCT quality of each batch of blood glucose results, how to solve issues in the application and ensure that patients' results are accurate and reliable. The hospital should put the POCT management under the whole management system and improve the accuracy of POCT to achieve the complete quality assurance. This article introduced the management program experiences of glucose POCT in Huashan hospital according to the JCI accreditation and CAP-LAP.

Objective:To establish a HPLC method for the determination of baicalin in Shangsuyu Spray.Methods:A Shim pack CLC ODS column was used. The mobile phase consisted of NH 4H 2PO 4 buffer (3.0) methanol (50∶50). The detective wavelength was 276nm.Results:The linear range was from 1.08 to 20.60?g/ml, r =0.9999. The recovery of the added sample was 100.5%. RSD was 2.5%. This method was easy to operate with accurate result, high sensitivity and good reproducibility.Conclusion:The method can be used for the determination of the contents of baicalin in Shangsuyu Spray.

Objective To compare the advantages and disadvantages of the two methods.Methods Thirty BALB/c mice were randomly divided into 3 groups:normal control group,OVA group and OVA/RSV group.With ovalbumin and hydroxide suspension sensitized,OVA nouse asthma model group and OVA/RSV group were established respectively by continuous atomization of ovalbumin and repeated nasal drops of RSV.The control group was established by sensitization and atomization excitation of sterile injection water.24 hours after the last stimulation,the lung function was measured.The cell sorting and counting in bronchoalveolar lavage fluid were performed.The pathological changes of lung tissue were observed by HE staining.Results Compared with the control group,the model groups have obvious symptoms of asthma,airway wall thickening,lumen stenosis and a large number of inflammatory cell infiltration.And pathological damage of lung tissue in OVA/RSV group was significantly increased,compared with OVA group.The enhanced expiratory pause (Penh)values of OVA/RSV group were significantly higher than those in group OVA (P ＜ 0.05),and the number of neutrophils,monocytes,lymphocytes and eosinophils in BALF were significantly higher than those in OVA group (P ＜ 0.05).Conclusion The establishment of asthma mouse model by OVA sensitization and RSV induction is a better way to simulate the human asthma pathogenesis.

It is always an important academic and policy issue to understand the impact of hospital distance on Chinese inpatient service demand in rural areas. It employs household survey data collected from 97 villages in Shandong in 2006 and 2008, and investigates the influences of hospital distance on the demand of famars in rural areas. The discrete choice model is constructed to estimate the inpatient service demand function for patients in rural areas. The empirical analysis finds that the hospital distance is significantly affecting Chinese inpatient service demand in the rural areas. The longer the distance increases, the lower the visiting rate drops. In addition, the impact changes with the changes of hospital level; the lower the primary hospital is, the higher the impact would be. It paper provides new evidence for the understanding of the geographical characteristics of medical health care.

Objective To explore the levels of serum chemokine in the patients with gastric cancer using cytometric beads array (CBA) and to find out the laboratory evidence for gastric cancer immunotberapy.Methods Forty-five patients with gastric cancer,thirty patients with benign gastric diseases and forty healthy controls were included.The chemokine levels of interleukin-8 (IL-8),regulated upon activation normal T-cell expressed and secreted (RANTES),monokine induced by IFN-γ (MIG),monocyte ehemoattractant protein-1(MCP-1) and interferon-γ induced protein-10 (IP-10) in serum of these three groups were measured using CBA ,then these data were analyzed using BD CBA analysis software.Results The levels of serum chemokines in healthy controls were (176.4±20.7) μg/L for IP-10,(111.3±17.2) μg/L for MCP-1,(503.9±47.2) μg/L for MIG,(472.4±116.7) μg/L for IL-8,respectively.In gastric cancer patients,the levels were (266.6±24.7) μg/L for IP-10,(100.4,70.8-193.5) μg/L for MCP-1,(1614±275.4) μg/L for MIG,(500.0±164.8) μg/L for IL-8.The levels of serum chemokines in patients with benign gastric disease were (207.9±31.7) μg/L for IP-10,(121.2±23.6) μg/L for MCP-1,(514.5±63.0) μg/L for MIG,(480.2±134.8) μg/L for IL-8,respectively.The levels of IP-10 and MIG among these three groups were significantly different (IP-10:F = 3.52,P < 0.05,MIG:F = 9.27,P < 0.01).The levels of IP-10 were elevated in the cancer patients compared with healthy controls (P < 0.05),while the levels of MIG were elevated significantly in the cancer patients compared with healthy controls and benign disease controls(t=3.29,P < 0.01,t=2.84,P<0.01).Conclusions CBA is a novel method with convenience,sensitivity and accuracy for the detection of serum ehemokines.The concentration of IP-10 and MIG in gastric cancer patients are elevated,indicating its implication in cancer pathogenesis and metastasis.Measurement of serum chemokines will lay the groundwork for therapeutic strategy in gastric cancer by inhibiting and anti-chemokine.

OBJECTIVETo assess the feasibility and safety of robot-assisted laparoscopic radical prostatectomy (RLRP) in the treatment of prostate cancer.

METHODSUsing the da Vinci robot surgical system, we performed RLRP for 34 patients with localized prostate cancer and analyzed the intraoperative and follow-up data.

RESULTSThe procedures were performed successfully in all the patients, with the mean operation time of 198 min (range 135-340 min), average blood loss of 257 ml (range 50-700 ml), and 1 case of blood transfusion, but no postoperative complications. Three cases had positive surgical margins. Postoperative examination at 4 weeks showed PSA > 0.2 microg/L in 2 cases, suggestive of residual tumor, for which maximal androgen block therapy was administered. The other 32 patients were followed up for 3-10 (mean 7.5) months, during which the average level of serum tPSA remained < 0.2 microg/L. Urinary continence was found in 94% (32/34) and 97% (33/34) of the patients at 3 and 6 months, respectively, of whom 77% (26/34) and 88% (30/34) had no urinary leakage (0 pad per day).

CONCLUSIONRLRP, with its advantages of less perioperative blood loss, low rate of positive margin, and good urinary continence, is a safe and effective surgical option for the treatment of prostate cancer.

Objective To investigate the expression of galectin-10 in CD4+CD25+CD127low/-regulatory T cells(Treg) and the correlation between expressions of galectin-10 and Foxp3.Methods CD4+CD25+CD127low/-Treg cells and CD4+CD25-CD127+ T cells were isolated from PBMC of healthy volunteers and lymph nodes of gastric cancer patients by flow cytometry.Following RNA micro-extraction RT-PCR analysis was used to detect mRNA expression of galectin-10 and Foxp3.Results The mRNA expression of galectin-10 and Foxp3 were dominant in Treg cells,whereas nearly no expression in CD4+CD25-CD127+ T cells.The results from PBMC of healthy volunteers and lymph nodes of gastric cancer patients were consistent between.Conclusion The expression of galectin-10 was obviously high in Treg cells,so it may become a novel marker for phenotypic characterization of Treg cells.

Objective The aim is to inquiring into the diagnosis and discrimination of systemic lupus erythematosus (SLE) complicated with centric nervous system (CNS) infection.Method The retrospective analysis of 14 patients with SLE and CNS infection was made.Results These patients were treated by corticosteroid for a long time before CNS infection.There were 4 patients with cryptococcal meningitis,3 with suppurative meningitis,5 with tuberculosis meningitis,1 with encephalopyosis and 1 with unclear diagnosis.Conclusion Pathogenic microbiological assay of cerebrospinal fluid is a reliable basis for diagnosis of SLE with CNS infection.The diagnosis of patients without pathogenic organism depends on original infection,manifestations,difference of cerebrospinal fluid and head CT.The differentiation of SLE complicated with CNS infection from SLE encepalophathy is important.
