Objective To evaluate the diagnostic value of current perception threshold (CPT) for diabetic peripheral neuropathy by comparing with nerve conduction velocity (NCV). Methods Sixty patients with type 2 diabetes were enrolled. The CPT and SNCV were examined respectively. Results The abnormal rates of the CPT and SNCV were 68.33％and 36.67％in all patients, respectively. The abnormal rates of the CPT and SNCV were 88.46％and 53.85％in symptomatic group. The abnormal rates of the CPT and SNCV were 47.06％ 17.65％ in asymptomatic group. In patients with disease less than five years, the abnormal rates of the CPT and SNCV were 55.17％ and 24.14％. In patients with disease greater than five years, the abnormal rates of the CPT and SNCV were 77.42％ and 48.39％. The abnormal rate was statistically significant difference (P<0.05) between two examination. Conclusion CPT and NCV were consistency in the diagnosis of diabetic peripheral neuropathy. For early asymptomatic patients, CPT have more advantages to inspect the sub-clinical patients.

OBJECTIVE:To investigate the clinical application of warfarin in inpatients of our hospital,and provide reference for standardized application in clinic. METHODS:Totally 267 inpatients records used warfarin in our hospital from Jan. 2013 to Jun. 2014 were investigated to retrospectively analyze the indications,dosage,international normalized ratio(INR)monitoring and bleeding complications of warfarin. RESULTS:Warfarin was mainly used for patients with deep vein thrombosis,cerebral infarc-tion,rheumatic heart disease and pulmonary embolism in our hospital;the dosage of inpatients was in the range of 0.625-6.875 mg with average daily dosage of (2.15 ± 0.72) mg;the INR lower than 1.8 accounted for 52.8%,the INR in the range of 1.8-3.0 (reaching the standard) accounted for 31.8% and INR higher than 3.0 accounted for 15.4%;incidence of adverse reactions was 5.6%,mainly subcutaneous blood spots (petechiae) and urine occult blood,and incidence of severe hemorrhage (intracerebral hemorrhage) was 0.7%. CONCLUSIONS:At present,the clinical application of warfarin is still deficient,and qualified rate of INR is still low. It's important to actively carry out medication intervention and clinical pharmaceutical care.

Obgective To investigate the clinical effect of Adenine arabinoside monophosphate (Ara-A) on the treatment of infant cytomegalovirus hepatitis.Methods One hundred cases of infants with cytomegalovirus hepatitis in the Third Affiliated Hospital of Zhengzhou University from January 2012 to October 2013 were included and divided into 2 groups:Am-A group treated with Ara-A [a course of treatment lasting for 2 months included 10 mg/(kg · d) for first 2 weeks followed by 2 weeks' interval,and then resumed],and then control group was given ganciclovir [10 mg/(kg · d) for 14 days and 5 mg/(kg · d) for 1 week after 1 week's interval,for a total treatment period of 1.5 to 2.0 months].Both groups were given conventional therapy.Both before and after treatment,liver function,time of jaundice and transaminase back to normal,quantification of viral DNA returns to negative,side effects,hospitalization time and cost were also compared.Results After 2 weeks,alanine aminotramferase(ALT) in Ara-A group was significantly lower than that of the control group,and there was significant difference (P ＜0.05).After 2 months,ALT,aspartate transaminase in Ara-A group were significantly lower than those in the control group (all P ＜ 0.05).Time of transaminase back to normal [(38.5 ± 16.7) d] was significantly reduced compared with the control group [(44.3 ±22.9) d] (F =3.845,P ＜ 0.05).Time of jaundice back to normal [(27.1 ± 10.5) d],quantification of viral DNA back to negative [(39.5 ±24.0) d],hospitalization time [(22.6 ±5.8) d] and costs [(10 521.9 ±2 662.3) yuan] in Ara-A group had no significant difference compared with those of the control group (F =1.111,2.837,0.840,2.223,all P ＞ 0.05).The negative rate of viral DNA quantification in Ara-A group (80.9％) was higher than that of the control group (62.1％),and the liver injury rate (7.1％) was lower than that of the control group (15.5％),and the difference was statistically significant (x2 =9.137,11.514,all P ＜ 0.05).Condusion Ara-A is safe and effective for infant cytomegalovirus hepatitis and it is suitable for the clinical practice.

Acute respiratory distress syndrome is an acute,progressive and inflammatory process of lung injury.The disease is very serious with the neonatal mortality as high as 30％-60％.In recent years,with the development of the study on the mechanisms of newborns with acute respiratory distress syndrome,a lot of new viewpoints on diagnosis and treatments have been explored.This review focuses on the recent advances on new mechanisms,diagnosis and therapy strategies of acute respiratory distress syndrome.

Objective To investigate clinical and experimental features of APL with tetraploid clone characterized by double t (15 ; 17). MethodsFive cases of APL with tetraploid clone characterized by double t(15;17) were chosen. Cytogenetic examination of bone marrow was performed with bone marrow or short-period culture. R banding technique was used for karyotype analysis. DNA content in one case was determined by flow cytometry. Immunophenotyping was performed by using a panel of monoclonal antibodies :CD2, CD13, CD15, CD33 and CD34. PML/RARα fusion gene was detected by interphase FISH using dualcolor PML/RARα probe in one case and by RT-PCR in two cases. ResultsAll cases were male with a median age of 38. Their marrow cell morphology examination showed marked hyperplasia with large leukemic cells that had bizarre nuclear configuration. Chromosome analysis revealed that a leukemia clone with tetraploid or near-tetraploid karyotype characterized by double t(15;17) (q22 ;q12) in five cases, of which, one also had a diploid clone with t(15;17) and a normal cell;two had some cells with normal karyotypes.PML/RARα fusion gene was detected by FISH in one of 5 cases and by RT-PCR in 2 of 5 cases. CD33 expression was found in one case. CD13 and CD33 expressions were seen in the other four cases, of which,CD34 or CD2 co-expression was found in one case and in two cases respectively. The result of DNA content showed a single peak which indicated only tetraploid clone whose DNA index was 1. 998 with CV of 8. 2%.All patients obtained complete remission after the treatment with ATRA and/or arsenic trioxide. Conclusions These results indicate that API, patients with tetraploidy and near-tetraploidy have giant and bizarre blasts.Most patients have short-type PML/RARα transcripts. The tetraploidy in APL does not appear to affect the response to treatment of ATRA.

Objective To explore the improve mechanism of the cerebral blood stream state in patients with cervical dizziness(CD) after treatment combined with traction and heating acupuncture.Methods The results of transcranial Doppler(TCD) were compared in 53 patients with CD being treated with traction and heating acupuncture.Results The results showed that in 53 CD cases after treatment the velocity of the blood flow of double middle cerebral arteries,posterior cerebral arteries and right anterior cerebral artery were decreased remarkablely,besides this left anterior cerebral artery.The TCD examined results got near to normal value of contrast group(P
