ObjectiveTo observe the effect of pioglitazone on the metabolism of glucose and lipid in patients with Impaired Glucose Regulation(IGR).Methods60 cases of IGR received conventional education on diabetes prevention,while the patients in intervention group(30 cases) accepted pioglitazone 15 mg once a day for 12 weeks.Blood pressure(BP),body weight,waist circumference,hip circumference were measured to calculate body mass index(BMI) and waist-hip ratio(WHR).The Fasting blood glucose(FBG),2 h postprandial blood glucose,glcosylated hemoglobin(GHb,HbA1C),fasting serum insulin(FINS),postprandial serum insulin(2hINS),total cholesterol(TC),triglyceride(TG),high-density lipoprotein cholesterol(HDL-C),low-density lipoprotein cholesterol(LDL-C),hepatic function,renal function were determined before and 12 weeks after intervention.ResultsAfter intervention,BP,BMI,FBG,2hBG,FINS,2hINS,HbA1C,TC,TG,LDL-C had been decreased significantly in intervention group(P<0.05 or P<0.01).There were significant differences between intervention group and control group(P<0.05 or P<0.01) in all indexes except body weight,WHR,hepatic function,renal function.ConclusionPioglitazone can obviously improve the metabolism of glucose and lipid in patients with IGR.

Objective To investigate the effect of excessive fluoride,aluminum on Zn,Fe,Ca,Mg,Cuin rat blood.Methods Forty eight SD rats were randomly divided into 4 groups matched with their weights:control group,high aluminum group,high fluorine group and high fluorine-aluminum group.Aluminum content in their drinking water was 0,90,0,90 mg/L respectively.Fluorine content of their feed was 5.2,5.2,106.0,106.0 mg/kg and aluminum Was 6.8,6.8,19.7,19.7 mg/kg respectively.90 days later,the level of blood Zn,Fe,Ca,Mg, Cu Was detected by the atomic absorption spectrometry.Results Compared among these groups,Zn,Fe,Mg and Cu content of the whole blood had significant difierences(F=46.25,14.74,6.10,2.93,P<0.05),while Ca content of the whole blood did not significantly change(F=2.81.P>0.05).Factorial analysis showed that excessive intake of aluminum could significantly decreased Zn,Fe,Mg content of the blood(F=42.66,5.41,7.04,P<0.05)and excessive intake of fluorine could significantly decreased Zn,Fe,Mg,Cu content of the blood(F=64.50,37.90,9.75,6.74, P<0.05).The coexistence offluorine and Muminum had interaction to the level of Zn(F=31.59,P<0.05)and did not obviously interact with other elements(F=0.91,1.63,1.51.0.00,P>0.05).Compared with the control group [(131.30 ±13.86)μmol/L,(10.24 ±1.02),(1.71 ±0.19)mmol/L,(20.43 ±4.42)μmol/L],Zn content in the high aluminum group[(90.84±9.98)μmol/L]decreased significantly(P<0.05),so did Zn,Fe,Mg content in tlle high fluorine group[(85.85 ±10.92)μmol/L,(8.49 ±0.68),(1.52 ±0.13)mmol/L],the difference being statistically significant(P<0.05)0Zn,Fe,Mg,Cu content in the high fluorine-aluminum group,being(82.82 ±11.00)μmol/L, (8.16±0.45),(1.46±0.09)mmoL/L,(15.69±2.38)μmol/L,respectively,all decreased signitlcarIdy(P<0.05). Compared with the high aluminum group[(9.43±1.09)mmol/L],Fe content of the high fluorine aluminum group[(8.16±0.45)mmol/L]decreased significantly(P<0.05).Conclusions Excessive fluoride can cause blood zn, Fe,Mg,Cu decline,so can excessive aluminum.Combination of excessive fluofine and aiuminum has 8ignificant synergic effect on the level of Zn but have rio influence on Ca.

Objective To investigate the relation of contrast-enhanced ultrasound ( CEUS ) characteristics and microvessel density ( MVD ) in the breast cancer .Methods From October 2010 to February 2012, 45 cases of patients with breast cancer were studied in Yantai Yuhuangding Hospital , Affiliated to Qingdao University Medical College .All lesions were examined by CEUS before surgery .The blood perfusion parameters such as rising time (RT),peak intensity(PI),time to peak(TTP),wash-in slope (WIS) and mean transit time ( MTT) were obtained by time-intensity curve ( TIC).Immunohistochemical staining for anti-factor CD34 was performed on surgery specimen and the MVD was evaluated .The CEUS characteristics and blood perfusion parameters between different MVD groups of breast cancer were compared.Results In 45 cases of breast cancer,mean MVD was(47.6 ±14.2)/high power field(HPD). Twenty-one cases(46.7%) were classified as high MVD group(MVD>48/HPD) and 24 cases(53.3%) were classified as lower MVD group ( MVD≤48/HPD) .Besides two cases without contrast agent perfusion in CEUS imaging, blood perfusion was observed in 43 cases (95.6%).Heterogeneous enhancement was observed in 25 cases(55.6%).Local blood perfusion defect was observed in 27 cases(60.0%).Irregular shape was observed in 37 cases(82.2%).Centripetal enhancement was observed in 25 cases(55.6%). Penetrating surrounding vessels was observed in 32 cases(71.1%).Poorly-defined margin was observed in 34 cases(75.6%).Compared with the surrounding normal breast tissue ,RT and TTP of center region of neoplasms was shorter[(9.3 ±3.3)s vs (11.1 ±3.7)s and (25.3 ±5.9)s vs (27.5 ±6.4)s],PI was higher[(12.1 ±4.6)dB vs (9.2 ±2.8)dB],WIS was higher(1.0 ±0.4 vs 0.8 ±0.3) and differences were significant(t =-3.001, -4.785,6.987 and 5.438,all P <0.05).Compared with center region of neoplasms,TTP of periphery region of neoplasms was shorter [(22.2 ±6.0)s vs (25.3 ±5.9)s],PI was higher[(15.4 ±5.1)dB vs (12.1 ±4.6)dB],WIS was larger(1.3 ±0.5 vs 1.0 ±0.4) and differences were significant(t=-2.839,3.194 and 3.151,all P<0.05).The detection rate of blood perfusion defect and heterogeneous enhancement was higher in the high-MVD group than in the low-MVD group(χ2 =4.0179 and 7.2024,both P <0.05).While the enhancement shape,margin and penetrating vessels showed no statistical difference between the two groups .Breast neoplasms in the high-MVD group had higher PI than those in the low-MVD group[(18.2 ±5.6)dB vs (12.9 ±3.1)dB,t=-3.738,P<0.05].While the RT, TTP and WIS showed no statistical difference between the two groups ( t=-0.798,-0.760 and -0.378, all P>0.05).Conclusion CEUS characteristics of breast lesions were associated with MVD ,which may reflect the microvessel distributional characteristics of neoplasm and may be one of bases used to evaluate neoplasm angiogenesis .

Objective To investigate the effects of Epigallocatechin gallate(EGCG)on IL-1βinduced MIN6 cells apoptosis. M.Methods The experiment group was divided into control group,IL-1β group,IL-1β+ EGCG low concentration group and IL-1β+EGCG high concentration group.Cell activity was detected by CCK8.Insulin secretion was detected by ELISA.cell apoptosis was detected by flow cytometry.The mitochondrial membrane potential was detected by flow cytometry.ATP content and cell ac-tivity of ROS were detected by colorimetry and chemiluminescence method.Results Compared with normal group,IL-1β group showed much lower cell activity,insulin secretion,cell mitochondrial membrane potential and ATP content,and at the same time IL-1βgroup had significantly higher cell apoptosis and ROS activities.After given EGCG,both low concentration group and high con-centration group had higher cell activity,insulin secretion,cell mitochondrial membrane potential and ATP content,at the same time lower cell apoptosis and ROS activities was showed.And the IL-1β+EGCG high concentration group worked more powerful.Con-clusion EGCG has protective effects on IL-1βinduced MIN6 cells apoptosis.Its mechanism may be related to increasing the content of the ATP and mitochondrial membrane potential and protecting mitochondrial function as well reducing the activity of ROS.

Fermentation for Eicosapentaenoic Acid(EPA) production by Nitzschia laevis at various temperature between 10℃ and 30℃ was investigated and the dynamics characteristics during fermentation process were also analyzed.Based on the results,a varying temperature nursing method of two stage control strategy is proposed:During the first stage,which comprises the delay phase and the initial index phase,the temperature is maintained at 25℃;then the temperature is shifted to 20℃ and kept up till the end of the fermentation process.By this method,a EPA content of 6.0% and a yield of 291.60 mg/L have been gained.These are 24.07% and 18.81% higher than that of fixed temperature(25℃) fermentation,respectively.

AIM:To investigate the expression of extracellular matrix metalloproteinase inducer(EMMPRIN)and hepatocyte growth factor(HGF)in non-small-cell lung carcinoma(NSCLC)and their relationship with lymphoid metastasis and prognosis.METHODS:Expression of EMMPRIN and HGF in 77 cases of patients with NSCLC was detected immunohistochemically.The relationship of expression of EMMPRIN and HGF with tumor size,smoking,histological type,differentiation,lymphoid metastasis,clinical stage,and prognosis was analyzed.RESULTS:The expressive rates of EMMPRIN and HGF were 68% and 44%,respectively.The expressions of EMMPRIN and HGF were associated positively with lymphoid metastasis(r=0.371 and 0.339,P0.05).The expression of EMMPRIN was associated with the expression of HGF in NSCLC.CONCLUSION:The expression of EMMPRIN and HGF is associated with lymphoid metastasis and prognosis in NSCLC.Overexpression of EMMPRIN and HGF implies infavourable prognosis in NSCLC.

OBJECTIVETo observe the therapeutic effect of Shennong No. 33 (SN33) in treating multiple organ dysfunction syndrome (MODS) by APACHE II and APACHE II scoring.

METHODSOne hundred and twenty-nine patients of MODS were randomly divided into the treated group (n = 72) and the control group (n = 57), they were treated with comprehensive therapy and to the treated group, SN33 was given additionally. The changes of APACHE II and APACHE III scores and blood endotoxin level were observed at the time points of within 24 hrs after hospitalization, and the 3rd, 5th and 7th day.

RESULTSIn the treated group, 50 patients survived and 22 died, while in the control group, 25 survived and 32 died. The APACHE II and APACHE III scores of the survivors were higher than those of the decedent (P<0.05), which in the treated group was lower than those in the control group (P<0.05). The blood level of endotoxin in the treated group was also lower than that in the control group (P<0.05).

CONCLUSIONSN33 in treating MODS could improve patients' condition, lead to the lowering of APACHE scores. APACHE scoring system could be applied as the criteria for evaluating the condition and prognosis of critical patients, and the APACHE III scoring is more accurate.

OBJECTIVETo compare the clinical efficacy in the treatment of allergic rhinitis (AR) of lung qi deficiency and cold syndrome between Jin's three-needle therapy and western medication.

METHODSSixty-six patients were randomized into an acupuncture group and a western medication group, 33 cases in each one. In the acupuncture group, acupuncture was applied at three-nose points [Yingxiang (LI 20), Shangyingxiang (EX-HN 8) and Yintang (GV 29); Cuanzhu (BL 2) was added for frontal headache] and three-back points [Dazhu (BL 11), Fengmen (BL 12) and Feishu (BL 13)], once every day. Ten treatments made one session. Two sessions of treatment were required. In the western medication group, desloratadine oral suspension was prescribed, 5 mg each time, once a day, for 20 days. The scores of the symptoms and physical signs in AR patients as well as the clinical efficacy were observed between the two groups.

RESULTSThe total effective rate was 93.9% (31/33) in the acupuncture group, which was better than 72.7% (24/33) in the western medication group (P < 0.05). After treatment, the scores of AR symptoms and physical signs as well as the total score were all reduced compared with those before treatment in the two groups (all P < 0.01). The score of every item in the acupuncture group was lower than that in the western medication group after treatment (score of symptoms: 4.70 +/- 2.07 vs 6.55 +/- 2. 69, score of physical signs: 0.85 +/- 0.67 vs 1.45 +/- +0.62, total score: 5.36 +/- 2.70 vs 8.00 +/- 2.91, all P < 0.01).

CONCLUSIONJin's three-needle therapy achieves superior efficacy on AR of lung-qi deficiency and cold syndrome, which is better than desloratadine oral suspension.
