Objective To explore the influence of shenmai injection on C-reactive protein(CRP) and homocysteine(Hcy) of patients with non-ST-segment elevation acute coronary syndrome.Methods 96 patients with nonST-segment elevation acute coronary syndrome were randomly divided into the control group(48 cases) and the observation group(48 cases).The patients in the control group were treated through the conventional treatment,while the patients in the treatment group were treated by shenmai injection based on the conventional therapy.They were all treated for 14 days.CRP and Hcy were detected before and after treatment.Results The total effective rate of the observation group was 95.8％,which was significantly higher than 87.5％ of the control group (x2 =4.760,P ＜0.05).The plasma levels of CRP and Hcy were all decreased after treatment in both two groups.The CRP and Hcy in the observation group were significantly lower than those in the control group (t =2.927,2.624,all P ＜ 0.05).Conclusion Shenmai injection can significandy decrease the plasma levels of CRP and Hcy in patients with non-ST-segment elevation acute coronary syndrome.

Clinical risk index for babies( CRIB) is applied in low birth weight preterm neonates to assess the initial severity of illness,predict mortality risk rates,evaluate their own performance,and audit the performance between different medical institutions.CRIB plays an important role in the progressive develop-ment of neonatology.The scoring rules and advantagse of CRIB scorni g system were introud ced in this arti-cle.Teh scoring system is able to correctly predict mortaliyt probabilities and long-term neurodevelopmental outcomes for low birth weight preterm infants.

Anti-neutrophil cytoplasmic antibodies( ANCA)-associated vasculitis ( AAV) has various clinical symptoms, thus various treatment schemes were used in clinics.To date, there has been no validated diagnostic criteria or treatment guideline for AAV.There are three aspects to be considered when assessing the treatment with AAV patients:staging of disease, distinction between disease activity and chronic damages, and quality of life ( QOL) .This review focuses on the latest classification of vasculitis, the rela-tion between disease stages and its severity, the importance of distinguishing active diseases from permanent damages, the therapeutic choices and the management of complications.

Objective To explore the most suitable condition of influenza virus which was culturing on plateau region,and im-prove the effect of the separation of influenza virus.Methods The original specimens were respective inoculated in MDCK cells,by comparing CO2 percent concentration (5%,4.8%,4.6%,4.4%,4.2%),TPCK-pancreatic enzyme dosage (1,2,3, 4,5μg/m and 6,8,10μg/ml),inoculation amount (100,200,300,400,500μl),incubation time (48,72,96,120,144 h),inoc-ulation methods (adsorption,direct inoculated),and culture vessel(cells,6 orifice)that were influenced on influenza virus, the best culture conditions was determined.Hemagglutinatio (HA)method was used to detect the virus titers.Results Through the comparison,the HA titer of virus was in the highest titer with 6 orifice plate culture vessel,4.4% CO2 and 4.6% CO2 ,2μg/ml TPCK-pancreatic enzyme,300μl and 400μl inoculation amount,72h~96h of incubation time.Conclusion The optimal condition of the influenza virus cultured with the MDCK cell has been established in the laboratory on plateau region.

OBJECTIVE:To evaluate the clinical efficacy of combination of low molecule heparin calcium with Asipilin for early acute cerebral infarction.METHODS:A total of 320 patients with early acute cerebral infarction were randomly assigned to low molecule heparin calcium group,aspirin group,combination treatment group(low molecule heparin calcium group plus aspirin)or control group.The clinical efficacy in 4 groups was evaluated respectively.RESULTS:The nerve function showed a better recovery in all the treatment groups than in control group.As compared with low molecule heparin calcium group or aspirin group,the combination treatment group showed a significantly improved nerve function and higher clinical efficacy.There were significant differences in total effective rate among groups after treatment for different time(P0.05).CONCLUSION:The combination of low molecule heparin calcium with Asipilin for early acute cerebral infarction is safe and more effective than low molecule heparin calcium and Asipilin used alone.

Objective To study the effect of femoral offset reconstruction ON the Harris hip score and the hip ROM (range of motion) after artificial hip replacement in femoral neck fractures. Methods Follow-ups were conducted for 47 patients who had undergone artificial hip replacements for their unilateral femoral neck fractures. We took X-ray pictures to compare the femoral offsets at the affected and unaffected hips. The operated hips were evaluated by the Harris hip score. Statistical analyses were performed with SPSS l2.0 software. Results The Harris hip score of the operated hip was positively related to femoral offset reconstruction(t=7.25,P＜0.001).There was a significant and positive correlation between femoral offset and the hip abductor ROM(r=0.80,P＜0.001).The rate of femoral offset reconstruction had no significant difference between total hip arthroplasty and bipolar hip arthroplasty (χ2=0,P＞0.05).Conclusions Reconstruction of femoral offset after artificial hip replacement in the femoral neck fractures can improve funetional recovery and ROM of the hip. Femoral offset reconstruction is uncorrelated to the selection of total hip arthroplasty or bipolar hip arthroplasty.

OBJECTIVE To investigate the evolution of drug-resistance of Staphylococcus aureus in children in Hubei tertiary level hospitals during four years and provide the evidence for clinically reasonable use of antibiotics.METHODS The summary data of drug sensitivity in clinical isolates of meticillin-resistant S.aureus(MRSA) and meticillin-sensitive S.aureus(MSSA) in children in Hubei tertiary level hospitals from 2004 to 2007 were investigated retrospectively and the results were analyzed statistically.RESULTS The tendency of infections with MRSA upgraded yearly during four years(5.7%→10.7%→40.8%→46.9%);the resistance rates of MRSA to various antibiotics were all higher than that of MSSA.The vancomycin-resistant S.aureus had not been detected.CONCLUSIONS The drug-resistance status of SA in Hubei is still very serious.We should adopt effective measurement to control the occurring and epidemic outbreak in combination with children physiological characteristic.

Objective To study the application value of multislice spiral CT angiography (MSCTA)in diag-nosis of intracranial aneurysms.Methods MSCTA was used to diagnose intracranial aneurysms in 40 patients with subarachnoid hemorrhage.Subtraction angiography digital (DSA)was used as the gold standard to evaluate the sensi-tivity,specificity and accuracy of MSCTA for diagnosis of intracranial aneurysms.Results In 40 patients,34 aneu-rysms were detected in 32 patients and they were all confirmed by incarceration of aneurysm.The aneurysms were de-tected in 33 cases by MSCTA,and the aneurysms were 34.Most of them were single (31 cases),1 case was multiple and 1 case was false positive.DSA was detected in 32 patients with 34 aneurysms,but single in 30 cases and multiple in 2 cases.DSA as the gold standard,the sensitivity,specificity and accuracy of MSCTA in diagnosis of intracranial aneurysms were 100%,87.50% and 97.50% respectively.MSCTA detected aneurysm neck width 1.85 -4.33mm, average aneurysm neck width was (3.65 ±1.85)mm.DSA detected aneurysm neck width 1.52 -4.48mm,average aneurysm neck width was (3.41 ±1.96)mm.The average tumor neck width detected by the two methods had no sta-tistically significant difference (t =0.78,P >0.05).But from the minimum of the detection,DSA still had certain ad-vantages.Conclusion The sensitivity of MSCTA for intracranial aneurysms was high.It can be used as a method for surgical treatment of intracranial aneurysms,but it still can not completely replace the DSA.

Dermcidin (DCD) was found in isolated human skin sweat glands with antimicrobial effect, and was defined as a kind of new small molecule antimicrobial peptide. It was a part of human sweat glands in the skin as the immune system's innate defense. With the studies of DCD, its extensive biological functions are gradually discovered. Since 2010, a number of studies have shown that DCD may be a new risk factor for atherosclerosis. And the role of DCD in ischemic heart disease has drawn increasing attention in particular its relationship with insulin secretion and glycemic control, nitric oxide (NO) synthesis and hypertension, platelet aggregation and acute myocardial infarction (AMI). In those experiments, it was also confirmed that aspirin had antagonistic and reverse effects on various biological functions of DCD. Further research on the role of DCD in cardiovascular and cerebrovascular diseases may lead to the prevention, early warning, prognosis evaluation and treatment breakthrough of cardiovascular and cerebrovascular events.
