Objective To investigate the incidence and the risk factors of the vascular disease in lower limbs of patients with type 2 diabetes(T2DM).Methods To retrospectively analyze 318 cases with T2DM patients.All the patients were checked on both lower limbs by color ultrasonic Doppler.The differences of ordinary and biochemical indicators between PVD group and non-PVD group were compared.Results There were 67.2％ (205/318) patients who had vascular disease in lower limbs with type 2 diabetes.Age,course of disease,HbAlC,TC,TG,SBP,DBP and BMI in PVD group were significantly higher than those in non-PVD group( P ＜ 0.01 ).Conclusion There was higher incidence of the vascular disease in lower limbs of patients with type 2 diabetes.And the independent risk factors were hypertension,hyperglycemia,hyperlipemia.It could help to prevent the development of lower limb blood vessel pathological changes in DM patients by controlling the levels of blood pressure,lipid and blood sugar strictly.

TCM is unique and e ective on senile dementia in both theory and practice;therefore it is signi cant to generalize TCM understanding and experience on senile dementia for speci c therapy to reduce patients' cognition impairment and enhance their living quality.Sorting of TCM understanding on senile dementia pathogenesis and causes,it was clear that seniledementia was often seen in aging people characterized by de ciency in origin and excess in super ciality.Its de ciency in origin was de ciency of kidney essence,marrow and lucid yang failing to ascend.The origin aspect of senile dementia was believed to be the insu ciency of kidney.The de ciency of ve zang-organs was closely related to it.While the super ciality aspect was thought to be turbid phlegm and stagnant blood blocking brain and cerebral meridian with ve zang-organs all concerned.On one hand,the de ciency of kidney assisted by the de ciency of ve zang-organs could result in phlegm and blood stasis,that is to say excess resulted from de ciency.On the other hand,the stagnation of phlegm and blood stasis could block the generation,transformation and transportation of qi,blood and body uid,which would further consume the essence of the body.This is so-called de ciency transformed from excess.The above two aspects a ected each other and causing lingering pathogenic factors.

ObjectiveTo study the clinical effect of treating acute exacerbation of chronic respiratory failure with Danhong injection.MethodsAccording to random number table,64 cases of acute exacerbation of chronic respiratory failure were divided randomly into 2 groups,with 32 cases in each group.Both groups were given correspondingly conventional symptomatic treatment(including oxygen,anti-inflammatory,antispasmodic,sputum,etc.).On this basis,the treatment group was added Danhong injection 30 ml+5％glucose infusion 250 ml,once a day,continuous therapy for 14 days.ResultsThe total effective rate was 87.50％ and 65.63％ in Danhong injection treatment group and conventional treatment group respectively,showing obvious difference between 2 groups (x2=4.267,P＜0.05).The blood low shear viscosity (7.11 ± 1.60) mPa ? s,high shear viscosity of whole blood (3.30 ± 0.83 ) mPa ? s,plasma viscosity ( 1.28 ± 0.32) mPa ? s,whole blood reduced viscosity ( 16.81 ± 3.32 ) mPa ? s,erythrocyte aggregation index ( 1.26±0.31 ),erythrocyte deformation index (0.64±0.27) in the Danhong injection treatment group all had statistical significance compared to the conventional treatment group(P＜0.05).ConclusionClinical efficacy and safety of Danhong injection in treating acute exacerbation of chronic respiratory failure were good.

Objective To investigate the effect of sufentanil on norepinephrine (NE)-induced contraction of thoracic aorta isolated from rats with spontaneous hypertension (SH) .Methods Eight male rats with SH weighing 250-300 g were used in this study. The rats were decapitated and their thoracic aortas were isolated and cut into rings 2-3 mm in length. The aorta rings were suspended for isometric tension recording. The aortic rings obtained from SH rats were divided into 4 groups ( n = 8 each) : control group and 3 sufentanil groups. The contraction of aortic rings in response to NE in the absence (control) and presence of 3 concentrations of sufentanil 7 × 10-11 ,2 × 10-10 and 1 × 10-9 mol/L was recorded. Results The amplitude of NE-induced contraction of thoracic aorta was significantly greater in 3 sufentanil groups than in control group. Sufentanil significantly inhibited the NE-induced aortic contration in proportion to concentration. Conclusion Sufentanil can inhibit NE-induced contraction of thoracic aorta isolated from rats with SH in a concentration-dependent manner.

Objective To investigate the prognostic value of CD44V6, MMP-9, p57kip2 and hCG in diagnosis differential diagnosis and malignant transformation of hydatidiform mole. Methods The expressions of CD44V6 MMP-9 and p57kip2 was detected by SP method and the serum hCG was detected with CLIA method in 55 cases of hydatidiform mole, 20 cases of abortion villi and 10 cases of normal villi, and the value of CD44V6, MMP-9, p57kip2 and hCG in diagnosis differential diagnosis and malignant transformation of hydatidiform mole was analyzed. Results There were 9 cases malignant transforming hydatidiform mole and 44 cases of non-malignant transforming hydatidiform mole(20 cases of complete hydatidiform mole, 26 cases of partial hydatidiform mole). The expression of CD44V6 MMP-9 and p57kip2 of malignant transforming mole was significantly higher than that of non-malignant transforming group (77.8 % vs 30.4 %, 77.8 % vs 34.8 %, 11.1 % vs 58.7 %) (P <0.05) and the expression difference of p57kip2 in complete mole and partial mole group (5.0 % vs 100.0 %) was statistically significant (P <0.05). HCG remained positive in 4 cases of hydatidiform mole and dropping and then rised in 5 cases. The sensitivity of p57kip2 in the diagnosis of partial hydatidiform mole was 100.0 %, the specificity was 95.0 %, the negative prediction was 100.0 %. The sensitivity of CD44V6 in the diagnosis of malignant hydatidiform mole was 77.8 %, specificity was 69.6 %, negative prediction was 94.1 %;The sensitivity of MMP-9 was 77.8 %, specificity was 65.2 %, negative prediction was 93.8 %. The sensitivity of the two combined detection (CD44V6 and MMP-9) was 88.9 %, negative prediction was 96.3 %. The sensitivity of combined detection (CD44V6, MMP-9 and hCG) was higher than any of them. Conclusion p57kip2 is an important marker in differential diagnosis of hydatidiform mole. CD44V6, MMP-9 play important roles in the process of transformation of hydatidiform mole. The combined detection of CD44V6, MMP-9, p57kip2 and hCG can help to diagnosis and differential diagnosis and predict biological behaviors and prognosis of hydatidiform mole.

Objective To explore the effect of CYP2C19 polymorphism on plasma minimum concentration of Voriconazole in children with hematological malignancies complicated with invasive fungal infection.Methods Twenty children with hematological malignancies complicated with invasive fungal infection were selected from the Department of Pediatrics,the First Affiliated Hospital of Zhengzhou University were selected,and 5 mL venous blood for each was extracted.CYP2C19 genotypes of the whole blood of all patients were detected by using the method of polymerase chain-reaction restriction -fragment length polymorphism(PCR -RFLP).All the patients were treated with Voriconazole at the same time and by the same way.Plasma concentration of Voriconazole was measured by the method of fluo rescence polarization immunoassay.The impact of CYP2C19 genotypes on plasma minimum concentration of voriconazole was analyzed by using the rank sum test.Results Typing results showed that the incidence of iuhomozygous extensive me-tabolizers (EM)genotype (CYP2C19* 1 /*1 )was 30%(6 /20 cases);the incidence of mixed sub extensive metaboli-zers (IM)genotype (CYP2C19*1 /*2 or CYP2C19*1 /*3)was 45%(9/20 cases),among which ,CYP2C19*1 /*2 was in 4 cases,CYP2C1 9*1 /*3 was in 5 cases;and that of poor metabolizer (PM)genotype (CYP2C1 9*2 /*2 or CYP2C1 9*2 /*3 or CYP2C1 9*3 /*3)was 25%(5 /20 cases),among which,CYP2C1 9*2 /*2 was in 3 cases, CYP2C1 9*2 /*3 was in 1 case,and CYP2C1 9*3 /*3 was in 1 case.The serum trough concentration of Voriconazole in EMgroup,IMgroup and PMgroup was(2.30 ±0.50)mg/L,(3.23 ±0.71 )mg/L,(4.84 ±0.29)mg/L,respec-tively.There was a statistically significant relationship between CYP2C19 genotype and plasma minimum concentration of Voriconazole (F =26.99,P =0.032).Conclusions CYP2C19 polymorphism has a significant effect on the mini-mum concentration of Voriconazole in children with hematological malignancies complicated with invasive fungal infec-tion,which indicates that administration of Voriconazole for clinical treatment should be based on individual CYP2C19 genotype.

AIM:To evaluate the expression level of CXC chemokine receptor 7 (CXCR7) in atherosclerotic apolipoprotein E-deficient ( ApoE-/-) mice induced by high-fat diet ( HFD) and the effects of atorvastatin on it .METH-ODS:ApoE-/-male mice (8-week-old) were used and were randomly divided into 3 groups following 1-week normal ro-dent diet:normal diet control (NDC) group , HFD group and HFD+statins (HFD+Sat) group.HE staining and oil red O staining were used to observe the atherosclerotic lesion burdens in the aortas .The expression of CXCR7 on the aortas was detected by Western blot and immunohistochemistry .The expression of Akt and endothelial nitric oxide synthase ( eNOS) in the aorta was determined by Western blot .RESULTS: Few lesions were found in the aortas in NDC group .Apparent atherosclerotic plaque burdens were seen in HFD group and HFD +Sat group, while the atherosclerotic plaque burdens in HFD+Sat group were notably reduced compared with HFD group .The protein levels of CXCR7, eNOS and Akt in aorta in HFD group and HFD+Sat group were significantly decreased compared with NDC group , while those in HFD+Sat group were increased compared with HFD group .The protein level of p-eNOS in the aorta and the concentration of NO in the plas-ma in HFD group were decreased compared with NDC group and HFD +Sat group.CONCLUSION: In ApoE-/-mice, HFD increases the lipid level and promotes the development of atherosclerosis by downregulating the expression of CXCR 7, Akt and eNOS.Atorvastatin reverses the above effect of hypercholesterolemia on the expression of CXCR 7, Akt and eNOS, thus playing the role in treating atherosclerosis .

BACKGROUND:The residual alveolar ridge in edentulous patients with osteoporosis always presents with a poor shape,which increases the difficulty in complete denture restoration.Until now,there are no predictors for residual alveolar ridge resorption or guidelines on the frequency of denture relines.OBJECTIVE:To investigate the correlation between the frequency of complete denture relines and serum bone turnover markers,osteocalcin (OC) and cross-linked carboxy-terminal telopeptide of type Ⅰ collagen (CTX),in elderly edentulous patients with osteoporosis,in order to provide reference for complete denture repair.METHODS:According to inclusion criteria,50 elderly edentulous patients with osteoporosis who had complete dentures were recruited in the study randomly.The frequency of complete denture relines was surveyed by related questionnaire and medical record,and the serum OC and CTX levels were detected by electrochemiluminescence immunoassay.Related data were analyzed statistically via Pearson correlation analysis.RESULTS AND CONCLUSION:It showed a strong positive correlation between the frequency of complete denture relines and the serum OC level (r=0.517,P ＜ 0.01).No significant correlation between relines frequency and the serum CTX level was observed (r=0.278,P=0.051 ＞ 0.05),but it showed a similar tendency between them.These findings indicate that to detect the levels of serum bone turnover markers may be conducive to evaluating curative effect of complete dentures in elderly edentulous patients with osteoporosis as well as to making subsequent diagnostic and therapeutic strategies.
