Objective To design a new type of fluorescence detection optical system for dedicated neonatal PKU screening. Methods The system selects super-luminance UVLED for excitation light source, uses different diameter quartz fiber and Y -type optical fiber which consists of glass fiber bundles, and self focusing optical fiber for collimating light and photomultiplier tubes for testing. Results The system has many features, such as simple structure, small size and high sensitivity. Conclusion The clinic screening requirements are met by the system and a new means of rapid detection is provided for PKU screening in large quantities.

Budd-Chiari syndrome is an uncommon but often fatal disorder resulting from obstruction of hepatic venous outflow tract at the level of the hepatic veins,the inferior vena cava. The CT and MRI charac-teristics of Budd-Chiari syndrome are reviewed in this article especially for displaying the exact site and extent of the obstruction. In addition to this direct sign,the indirect findings of venous obstruction such as the presence of intra-and extrahepatic collateral veins,caudate lobe enlargement,inhomogeneous liver enhancement,and regenerative nodules can also be demonstrated. Awareness of these findings is important for early diagnosis and appropriate treatment.

Objective To study whether ANCA liter is sensitive serological marker reflecting vasculitis disease activity. Methods MPO-ANCA and IF-ANCA tilers variation in five sera specimen with active MPA diseases were studied after methylprednisolone and cyclophosphamide pulse therapy. The clinical and pathological features of 5 patients with MPA were investigeted comparing pre-treatment with post-treatment. Results (1) Serum ANCA were found positive and increased liter in 5 patients wilh active MPA disease. (2) Titer decreased after Ireatment, while renal function improved. (3) After half year, MPO-ANCA was negative in 5 patients, IF-ANCA was negative in 2 patients. Conclusion There is a close correlation between serum ANCA titer and MPA renal disease activity.

Small cell lung cancer (SCLC), which accounts for about 15%of lung cancer cases, is an aggressive disease characterized by rapid growth and early widespread metastasis. Despite sensitive to chemotherapy and radiotherapy, SCLC is vulnerable to get resistant and has high recurrence rates. Therefore, novel therapies are desperately needed to improve treatment efficacy and increase overall survival. A complex molecular biological alteration of SCLC accounts for its pathogenesis and chemo-resistance. With the understand-ing of SCLC biologic behavior and improvement of detection technique, immunotherapy may be a viable therapeutic approach and bring breakthrough to the treatment of patients with SCLC. In this review, we will discuss the rationale for immunotherapy and recent clinical trials of immunotherapeutic agents for SCLC.

The effects of Da Huai Mixture on receptor dependent and independent pathways of LDL catabolism of the experimental hypercholesterolemic rats were observed by isotope trace-labelling, measurement of monocytic macrophage function and dot bloting. The results were as follows: (1) Serum total cholesterol was significantly decrcased(P

Along with the fast development of medical technology,the theory of holistic medical care is infiltrated into every aspect of clinical medical practices.In this paper,though the treatment of surgical hepatobiliary diseases under the direction of holistic medical care ,we emphasize the significance of holistic medical care in diagnosis and treatment ,recommend and canonize the usage of holistic medical care into the clinical practices.

Objective: To investigate prognostic factors of survival of lung adenocarcinoma patients with brain metasta-ses.Methods: The clinical data of 109 lung adenocarcinoma patients with brain metastases were reviewed.Fifty-senven pa-tients survived more than 1 year, and 52 patients survived less than 1 year.The data were analyzed by SPSS 15.0 statisti-cal software.Results: Both the univariate analysis and multivariate analysis showed that patients' PS score, the interval be-tween diagnosis and brain metastasis, and multimodality treatment were independent prognostic factors for the survival of lung adenocarcinoma patients with brain metastases (P<0.05).Patients' gender, age, metastatic symptoms and extracrani-al metastases didn't significantly affect patient survival.Conclusion: Patients with PS score 0-1, the interval of more than 1 year between diagnosis and brain metastasis, and combined therapy have longer survival.The research provides an impor-tant guidance for the treatment of advanced lung adenocarcinoma patients with brain metastases.

Objective To investigate the predictive value of serum histone deacetylase 3(HDAC3) ,cystatin C(CysC) and albu‐min levels on a large area of myocardial infarction .Methods According to whether heart failure and (or) cardiogenic shock occur‐ring during hospitalization ,102 patients with acute myocardial infarction(AMI) were divided into the two groups :the non - compli‐cating heart failure and (or) cardiogenic shock group(n= 63) and the complicating heart failure and (or) cardiogenic shock group(n= 39) .Then according to whether the creatine kinase(CK‐MB) peak value was greater than 200 IU /L ,102 AMI patients were di‐vided into two groups :CK‐MB peak values ≥ 200 IU /L group(n= 58) and the CK‐MB peak values < 200 IU / L group(n= 44) .The serum HDAC3 ,CysC and albumin levels were detected at early morning on 2 d of admission in all patients .Results Compared with the non - complicating heart failure and (or) cardiogenic shock group ,serum HDAC3 and CysC levels in the the complicating heart failure and (or) cardiogenic shock group were significantly increased(P< 0 .01) ,while serum albumin protein level was significantly in the occurrence of heart failure and(or)cardiogenic shock group .Compared with the CK‐MB peak value < 200 IU /L group ,serum HDAC3 and CysC levels in the CK‐MB peak value > 200 IU /L group were significantly increased (P< 0 .01) ,while serum albumin level was significantly decreased(P< 0 .01) .Conclusion Serum HDAC3 ,CysC and albumin levels have certain predictive value on a large area of myocardial infarction and conduce to judge the prognosis of patients .

Spinal cord injury is a common clinical disease .Cell apoptosis is one of important pathogeneses for spinal cord in-jury, and apoptotic gene plays a very important role in apoptosis on spinal cord injury .Chinese medicine for blood-activating and stasis-dissolving has a good therapeutic effect for spinal cord injury by reducing inflammation , inhibiting apoptosis and improving microcircu-lation.In this paper, we review the research of chinese medicine for activating blood and resolving stasis during the regulation of apoto -sis gene in spinal cord injury based on related documents in the recent five years .
