Objective To analyse subclavian steal syndrome(SSS)by transcrinial Doppler ultrasound (TCD)and to explore the rdationship between the different degrees of subelavian artery(SUBA)and the degree of steal blood vertebral artery and clinieal value of TCD.Methods Thirty seven patients of SSS were divided into three groups according to vdoeity of SUBA and direction of vertebral artery.The stenosis of SUBA and steal degree were compared.Results Mild and moderate stenosis of SUBA were found in 15 cases with no steal and stage Ⅰ steal in 12 cases(80%);Severe stenosis of SIJBA was found in 14 cases with no steal and stage Ⅰ steal in 3 cases(21%),with significant difference between the two groups(P＜0.05).In mild and moderate stenosis group,there were 3 cases of stage Ⅱ and Ⅲ steal(20%)while in severe stenosis group there were 11 cases of stage Ⅱ and Ⅲ steal (78%),among which,the signifieant difference(P＜0.05)was observed.Stage Ⅲ steal was found in 2 cases of severe stenosis group(14%)and 7 cases of occlusion group(87%),with significant difference(P＜0.05).10 cases were found to have bilateral SUBA stenoeis,including 1 case of bilateral steal.4 cases underwent digital subtraction angiography(DSA)which results were in accordance with the results of TCD.5 cases underwent CT angiography,the results of 3 of which were similar with TCD but 2 cases did not show any abnormality.Steal happened from vertebral artery(VA)-VA in 28 cases(75.6%)and basal artery(BA)-VA in 9 cases(24.4%).Conclusion TCD could be used to diagnose SSS and the degree of steal blood.The degreo of SUBA stenosis is related to degree of vertwbral artery steal.

ObjectiveTo explore the diagnosis value of color Doppler ultrasound of the carotid atherosclerosis plaques in diabetic patients. MethodsColor Doppler ultrasonic assessment of carotid was performed in 124 diabetic patients(test group)and 100 normal controls(control group).The intima-media thickness(IMT)and the carotid atherosclerosis plaques parameters were measured.The results were compared and analyzed between two groups. ResultsThe IMT and the incidence rate of carotid atherosclerosis plaques in the test group were higher than those in the control group(all P＜0.05).There was no statistical difference in the site of the plaques between test and control group(P＞0.05). ConclusionThe incidence rate of the carotid atherosclerosis of type 2 diabetes was higher.Carotid color Doppler ultrasonography was an optimal technique for screening and diagnosing atherosclerosis.

Current definition of apnea of prematurity (AOP) with the time of breathing cease equal or more than 20 seconds,or less than 20 seconds accompanying with bradycardia and(or) cyanosis was absence of strong clinical evidence and arbitrary.We have no consensus on the treatment of AOP,but severe AOP will lead to the intermittent hypoxic episodes(IHE) and severe fluctuation of oxygen saturation associated with severe retinopathy of prematurity and bad neurodevelopmental outcome.IHE occurred not only due to AOP,but also in the processes of continuous positive airway pressure and invasive ventilation.Decreasing the IHE is one of key problems of preterm respiratory support.Optimal target oxygen saturation should be regulated dynamically,the target oxygen saturation of 90％ ～ 95％ lowers IHE and mortality,but likely increases retinopathy of prematurity.Caffeine,the first choice of AOP,may be no of effect in the mixed or obstructive AOP which may need more respiratory support to reduce the lung volume loss and airway resistance.

Objective To explore the clinical value of Thinprep cytology test (TCT)combined with h -TERC and c -myc in the diagnosis of cervical cancer.Methods hTERC amplification was detected by dual -color interphase fluorescence in situ hybridization (FISH),and the results were compared with TCT and histological examination.Examination the positive which TCT,h -TERC and c -myc by pathological examination.The final diag-nosis was determined by the pathological examination.Results TCT was abnormal in 26.4% of 500 case,18.0%abnormal h -TERC gene,16.0% abnormal c -myc gene.In 270 cases according to the cervical biopsy,the positive rate of chronic inflammation,cervical intraepithelial neoplasia (CIN)Ⅰ,CINⅡ,CINⅢ and cervical cancer:44.4%, 38.2%,36.4%,18.2%,and 7.3% respectively.The positive rates of h -TERC were 18.1%,45.4%,52.5%, 65.9% and 100.0%,respectively.The positive rates of c -myc were 21.4%,48.9%,56.7%,59.9% and 100.0%.With increased pathological grade,the expressions of h -TERC and c -myc were high.Conclusion TCT combined with h -TERC and c -myc can test cervical cancer more effective.

Objective To investigate the clinical efficacy of trimetazidine combined with atorvastatin in the treatment of patients with coronary heart disease and its influence on serum lipid and hemorheology.Methods 140 cases with coronary heart disease were randomly divided into two groups.The control group was given trimetazidine on the basis of the conventional treatment,while the observation group was given atorvastatin on the basis of the control group.The clinical efficacy,changes of hemorheology and blood lipid were compared between the two groups.Results The effective rate of the observation group was 95.71％,which was significantly higher than 77.14％ of the control group (x2 =10.620,P ＜ 0.05).After treatment,TC,TG,LDL-C and HDL-C of the observation group were (2.54 ± 0.32) mmol/L,(1.41 ± 0.32) mmol/L,(1.53 ± 0.33) mmol/L and (0.73 ± 0.35) mmol/L,which were significantly lower than those of the control group (t =7.42,8.09,8.11,9.03,all P ＜ 0.05).After treatment,the nbh,nbl,np and HCT of the observation group were (5.11 ± 0.51) mPa/s,(8.03 ± 1.12) mPa/s,(1.02 ± 0.21) mPa/s and (40.34 ± 3.28) ％,which were significantly lower than those of the control group(t =8.33,9.14,8.08,9.44,all P ＜ 0.05).Conclusion Trimetazidine combined with atorvastatin in the treatment of coronary heart disease can significantly improve patients' lipid and hemorheology,and it can be promoted and applied in clinical practice.

Frequently,there is a lack of safety data about diagnostic method and drug therapy of digestive diseases during pregnancy. It is profitable to understand the limited evidences of safety data about diagnosis and drug therapy of digestive diseases during pregnancy,which will allow the accurate evaluation and risk assessment on diagnostic method and treatment during pregnancy. High-quality clinical study on patients with pregnancy is helpful for the management of common digestive diseases among this special population.

Bacterial meningitis is one of the most common infectious diseases of the central nervous system in childhood,with high mortality and disability rate despite available treatment.Studies have shown that the host's immunity dysfunction after the infection plays a central role in neurological sequelae.The deposition and activation of complement component C3 on the bacterial surface is a key step in the complement cascade leading to elimination of the microbe,and the level of complement component C3 or C5 in cerebrospinal fluid may predict outcome of bacterial meningitis.After the microorganisms cross the blood-brain barrier,bacterial compounds are recognized by pattern recognition receptors,triggering the production of excessive cytokines,attracting leukocytes and generating oxidative stress,which contributes to neuron injury irreversibly.This review focuses on current research progress on immunology associated with pneumococcal meningitis.

In This article we report 80 cases of psoriasis confined to the leg hand or foot of the patients. The diagnoses all been confirmed by definite pathological examinations of the cutaneous tissue. As this disease appears on peculiar sections of the body is affected by many physio-chemical factors, the form of cutaneous damage produces different changes of various degrees, so the typical damage is not shown usually. Therefore misdiagnosis leads us to consider it to be case of neurodermatitis, eczema, chronic dermatitis and tinea. The author has made analysis on causes of misdiagnosis and suggested methods to discern proper diagnosis of this disease.
