Hyperglycemia is common in patients with aneurysmal subarachnoid hemorrhage (aSAH),and it has important association with dehyed cerebral ischemia (DCI) and may result in poor prognosis.This article summarizes the mechanism of the elevated blood glucose after aSAH,the reasons of causing DCI,and the corresponding treatment measures.

mia and hypertension are the major risk factors for occurrence of diabetic retinopathy.High UA may be also associated with occurrence of diabetic retinopathy.

To investigate the therapeutic effect of Lamivudine on reinfection of hepatitis B virus, seven patients with terminal HBV related hepatic diseases who had received orthotopic liver transplantation, were studied. Among them, 5 patients were treated with lamivudine bcfore and after liver transplantation, and 2 patients received common antiviral treatment. No hepatitis B virus reinfection and YMDD mutations occurred in the group of patients with Lamivudine therapy. However in the group of patients receiving common antiviral therapy, both patients suffered from hepatitis B virus reinfection. Lamivudine is potentially effective in the prophylaxis of hepatitis B virus reinfection after orthotopic liver transplantation.

This study was designed to investigate modulation of phosphorothioate oligodexynucleotides of laminin receptor on MMP 2 and MMP 9 gene expression in human bile duct carcinoma cells. Treated with a concentration of 12?mol/L LNR AS OD in cuture medium, the relative MMP 2 and MMP 9 mRNA level at 72h in human bile duct carcinoma cells was evaluated by reverse transcriptase polymerase chain reaction. The results showed that the expression of MMP 2 and MMP 9 dropped obviously by AS OD group as compared with control group. The relative expression level of MMP 2 and MMP 9 gene mRNA decreased about 33 2% and 23 9% respectively. It is suggested that LNR AS OD is the regulator of MMP 2 and MMP 9 gene expression. It can decrease MMP 2 and MMP 9 gene expression in human bile duct carcinoma cells. Understading the regulation of MMP 2 and MMP 9 gene expression in human bile duct carcinoma cells might contribute to the development of a new preventive and theraputic strategy for tumor invasiveness.

Objective To establish a new renal cancer cell line so as to provide an useful tool for the basic research of renal cancer. Methods A renal tumor specimen sized 1.0 cm?1.0 cm was excised and inoculated subcutaneously into the right posterior leg of three nude mice.After three passages in the nude mouse,the tumor tissue was cultured in vitro. Following the reference, the identification of cell line were fulfilled. Results Two of the transplanted tumors grew in the nude mice and then part of the tumor was cut and inoculated again into nude mouse for another two generations. The tissue cultured in vitro was followed and finally a stable growth renal carcinoma cell line was established without change of morphological structure and differentiation. The mode rage of chromosome has been 62～68 (75%) and the cycle analysis showed G1 63.8%, G2 11.4% and S1 24.8%.The doubling time has been 37.7 hours.The tumor cell can secrete IL 6 continuously. Conclusions The renal carcinoma cell line RCC 9863 was identical to the primary cancer cell in biological characteristics.It has been cultured in vitro continually for more than one year with its characteristics remained.So,RCC 9863 is considered to be a stable cell line.

Objective To establish a SOI model of human renal carcinoma and a high metastatic cell subline. Methods A human renal cell line RCC-9863 has been established by inoculating a human renal tumor tissue into nude mice s.c..When RCC-9863 passaged for 20 times,the tissue from the same xenotransplant tumor were used to construct SOI model.Cultured the metastatic tissue in vitro,the tumor cell suspension was then injected orthotopically.The metastatic tissue obtained underwent the same procedure again.At last,the metastatic tumor was cultured in vitro and cloned. Results 15 days later, a tumor mass sized 1.7 cm?0.6 cm in the nude mouse's renal parenchyma was grown which lobulated,rude,and with multiply blood vessels and 55 days later the mouse became moribund and metastases in the lungs were formed.The transplanted renal tumor in the SOI model grew fast and invasively and metastasized to lungs,lymphatic node and liver.A subline,MRCC,with metastatic ability to the lung was selected.Compared with RCC-9863,MRCC has the characteristics of shorter multiply time and higher agar clone forming rate(P

OBJECTIVE:To explore the clinical efficacy and safety of cetuximab combined with NP regimen and radiotherapy in the treatment of advanced non-small cell lung cancer(NSCLC). METHODS:76 cases of advanced NSCLC were selected and randomly divided into control group and observation group according to different therapy methods,with 38 cases in each group. Control group received NP regimen(cisplatin 25 mg/m2+navelbine 12.5 mg/m2)+thoracic IMRT;observation group was additional-ly given cetuximab 400 mg/m2(first day),with maintenance dose of 250 mg/m2 weekly and last for 13 weeks. Short-term efficacy, survival situation were compared between 2 groups as well as the levels of T lymphocyte,Th1,Th2,immuneglobulin(Ig) and complement. The occurrence of ADR was recorded. RESULTS:The total effective rate of observation group was 86.84%,which was significantly higher than that of control group(65.79%),with statistical significance(P<0.05). Average survival period and 2-year survival rate of observation group were 18.70 months and 55.26%,which were significantly longer or higher than those of control group (14.75 months,31.58%),with statistical significance (P<0.05). The improvement rate of survival quality was 94.74% in observation group,which was significantly higher than 68.42% in control group,with statistical significance (P<0.05). After treatment,the levels of CD4+,CD4+/CD8+ and IgG were significantly increased in 2 groups,while the levels of CD8+, Th1,Th2 and Th1/Th2 were significantly decreased;the observation group was better than the control group,with statistical signifi-cance(P<0.05);there was no statistical significance in the levels of CD3+,IgA,IgM and complement 4 between 2 groups(P>0.05). There was no statistical significance in the incidence of ADR between 2 groups (P>0.05). CONCLUSIONS:Cetuximab combined with NP regimen and radiotherapy can improve clinical efficacy of advanced NSCLC,improve survival quality,prolong survival time and promote the recovery of Ig,complement and T lymphocyte,with good safety.

Purpose To investigate the effect of two different 1.5T MRI scanners on the apparent diffusion coefficient (ADC) measurement and its reproducibility in diffusion weighted imaging (DWI) of the liver. Materials and Methods Two groups of volunteers (33 people in each group) underwent liver DWI examination twice by using the same DWI sequence with b value of 0 and 800 s/mm2 on different MRI scanners (1.5T Siemens Espree and 1.5T Philips Achieva). On ADC maps, two region of interests were placed on three central slices of the left and right liver lobes, respectively. The ADC measurements of six region of interests on left and right liver lobes were averaged to represent the mean ADC values of the left and right liver lobe, respectively. The reproducibility of the ADC measurements was assessed by Bland-Altman method. Results The ADC values of the left and right liver lobes measured on Siemens MRI scanner were significantly higher than those on Philips MRI scanner (t=2.045-2.713, P<0.05); on both scanners, the ADC values of the left liver lobe were significantly higher than those of the right liver lobe (t=-10.561--7.263, P<0.001). The Bland-Altman results showed that the reproducibility of ADC measurement was similar on both MRI scanners, and both displayed higher reproducibility of right liver lobe than that of left liver lobe (on Siemens MRI scanner: the agreement were 16.65% and 7.55% for the left and right liver lobe, respectively;and on Philips MRI scanner:16.30%and 7.85%, respectively. Conclusion Different MRI scanners may have influence on ADC values, but does not affect its reproducibility. Therefore, when ADC values obtained on different MR scanners are compared in clinical analysis, this influence should be considered.

Objective To investigate the feasibility of magnetic resonance diffusion-weighted intravoxel incoherent motion (DW-IVIM)imaging and its reproducibility in normal liver.Methods Thirty-five young healthy volunteers underwent liver DW-IVIM ex-amination twice on a 1 .5 Tesla Philips MR scanner.Parameter maps of D,D* and f were generated by using a manufacturer-sup-plied software.Six Region-of-interests (ROIs)(3 ROIs in left and right liver lobe,respectively)were drawn on three consecutive middle slices,respectively.The average values of D,D* and f were measured and compared between the left and right liver lobe. The reproducibility of D,D* and f measurement were assessed with Bland-Altman method.Results The values of D,D* and f of left liver lobe [D(×10-3 mm2/s):1.250±0.210,D*(×10-3 mm2/s):101.906±15.063 ,f(%):22.954±5.268]were statistically higher than those of right liver lobe[D(×10-3 mm2/s):1.039±0.124,D*(×10-3 mm2/s):100.127±20.757,f(%),18.317± 3.671](D,f,P<0.001,D*,P<0.232-0.605),however ,their reproducibility of left liver lobe [limit of agreement(LOA):22.55%,51.05%,39.3%,respectively]were lower than those of right liver lobe (LOA:20.3%,39.25%,33.9%).The D values had the best reproducibility in both the left and right liver lobe.Conclusion The liver DW-IVIM is feasible.The values of D,D*and f in left liver lobe were higher that those in right liver lobe but with worse reproducibility of measurement.The D value was most reproducible in both liver lobes.

OBJECTIVEThis study aims to evaluate the optical data of the different sites of the cobalt-chrome (Co-Cr) alloy abutments covered by four different all-ceramic crowns and the color difference between the crowns and target tab using a digital dental spectrophotometer.

METHODSTen Co-Cr alloy abutments were made and tried in four different groups of all-ceramic crowns, namely, Procera aluminia, Procera zirconia, Lava zirconia (Lava-Zir), and IPS E.max glass-ceramic lithium disilicate-reinforced monolithic. The color data of the cervical, body, and incisal sites of the samples were recorded and analyzed by dental spectrophotometer. The CIE L*, a*, b* values were again measured after veneering. The color difference between the abutments covered by all-ceramic crowns and A2 dentine shade tab was evaluated.

RESULTSThe L* and b* values of the abutments can be increased by all of the four groups of all-ceramic copings, but a* values were decreased in most groups. A statistical difference was observed among four groups. After being veneered, the L* values of all the copings declined slightly, and the values of a*, b* increased significantly. When compared with A2 dentine shade tab, the ΔE of the crowns was below 4.

CONCLUSIONFour ceramic copings were demonstrated to promote the lightness and hue of the alloy abutments effecttively. Though the colorimetric baseline of these copings was uneven, veneer porcelain can efficiently decrease the color difference between the samples and thee target.
