Inflammatory reaction plays an important role in the occurrence and development of ischemic stroke. Monocyte chemotactic protein-1 (MCP-1) is one of the subfamily members of the CC chemokine class. It can attract and activate a variety of cells, such as monocytes and T lymphocytes, promote the expression of cytokines, and participate in the occurrence of ischemic brain injury. This article reviews the progresses on the MCP-1 and ischemic stroke-related research.

Objective　To study the role of the structural gene variation of hepatitis C virus(HCV) in the chronicity of HCV infection. Methods　Serum samples from four HCV infection acquired during six-month follow up and four patients with chronic hepatitis C type were obtained. A 1-kb fragment containing the 3' half of core ，completed E1 and 5' half of E2/NS1 was amplified by nested reverse transcription polymerase chain reaction (RT-PCR). For each，30 cloned cDNAs were examined by a method that combined heteroduplex analysis (HAD) and a single-stranded conformational polymorphisim (SSCP)assay to optimize selection of clones with unique gel shift patterns (clonotypes )as a measure of the quasispecies complexity. Results　There was obvious difference between the SSCP bands of cloned cDNAs representing core-E1 and E2 region，but more distinct difference between heteroduplex and the homoduplex of clones spanning E2 region which accurately reflected the degree of heterogeneity. Quasispecies complexity was higher in those with persistent viremia than those with acute viremia. Conclusion　HCV persistence is associated with complex quasispecies in viral structural region.

Objective To discuss the prenatal diagnosis of abnormalities of fetal limb bone.Methods We selected 18 cases which long bone of fetus less than 2SD of average volume of gestational weeks or long bone changed into angle or other fetus's abnormalities by first B-mode ultrasonic. All above cases was delivered at Capital Medical University of Obstetric and Gynecological Hospital during Jan. 2006 to Dec. 2009. We B-mode ultrasonic was used to measure fetus's biparietal diameter (BPD) ,femur length (FL) ,abdominal circumference(AC) ,head circumference(HC) ,humerus length (HL) ,amniotic fluid index (AFI) and structures of organ and calculated FL/AC, growth speed of long bone. The standard of achondroplasia is that FL and HL are less than 4SD of average of gestational weeks or FL/AC less than 0. 16. The standard of Osteogenesis Imperfecta is fetal long bone of fetus shows short and thick, curves into angle, fracture in uterus by X-ray, or skull shows thin or sink by X-ray. Results (1) By B-mode ultrasonic and X-ray exam of all 18 cases: 7 cases shows that HC ＞2SD, 10 cases shows too much amniotic fluid, 12 cases shows AFI ＞ 18.0, 9 cases shows abnormalities of narrow cavitas thoracis, disordered vertebral column, or unusual architecture of heart. For cases 1 to 14 are achondroplasia, among which,11 cases are FL＜4SD and HL＜4SD, 2 cases are FL ＜3SD and HL ＜4SD, 1 case is not only FL ＜2SD and HL ＜3SD but also hydroncus all over the body of fetus. The growth velocity of long bone of fetus in all the 14 cases is more slowly than the normal rate. For all the above 14 cases, 12 cases FL/AC ＜0. 16, 1 case FL/AC =0. 19, 1 case FL/AC =0. 20. The length of femur or humerus is shorter than the normal rate and have other abnormalities the above last two cases. For case 15 and 16, they don't show any abnormalities of bone growth though one year's follow up studying. For case 17 and 18, they are osteogenesis imperfecta. (2) The result of fetal perinatal period fate and autopsy: there are 8 female and 10 male in all the 18 cases. One case is labored after 39 weeks pregnancy, and it is low birth weight infant, weight ＜3%th. All the other cases are normally birth weight infant. All the 18 cases of abnormalities of fetal limb bone are examined by chromosomes check, among which, 9 cases are amniocentesis, 7 cases are cordocentesis,2 cases are checked chromosomes by fetus cord blood, all the caryotype are normal. In the 16 autopsy cases,14 cases are achondroplasia or hypochondroplasis. It can be seen amplifying extremities, hyperplasia chondrocytes of tubiform born, karyomegaly, anachromasis, hyperplasia capillaries though microscope and grow up into cartilage irregularly. Also can be seen hyperplasia chondrocytes of epiphyses, delaying osteosis.2 cases are osteogenesis imperfecta. It can be seen broadening of metaphyses, exility of bone trabeculae. For the other two cases which the fetus is alive, we do the follow up studying to their one year old one of them is low birth weight new born, their limb and height are all normal. Conclusions To diagnose fetal Achondroplasia, it is not only based on the significantly shorter of femur or humerus length but also based on the dynamics observing the long bone growth velocity and calculating FL/AC. For osteogenesis imperfecta fetus, it should be diagnosed by fractures in uterus though X-ray.

Objective To compare effect of the GlideScope and direct laryngoscopy in snoring surgery.Methods Fourty patients scheduled for orotracheal intubation of general anesthesia in snoring surgery wererandomly divided into GlideScope group ( A group) and direct laryngoscope group ( B group). Two groups were recorded values of heart rate (HR),systolic blood pressure (SBP), diastolic blood pressure (DBP)before induction (T1), after induction (T2), intubation (T3) and 1 (T4), 3 (T5), 5 (T6) min after intubation and plasma norepinephrine (NE) concentrations in T1, T5, T6. Results ( 1 ) Values of HR, SBP and DBP of two groups were compared in T1 and T2, the difference was not significant ( P ＞ 0.05 ); Values of SBP and DBP of two groups compared T1 to T2, and the difference was significant ( P ＜ 0. 05); (2) Values of HR, SBP and DBP of two groups compared in T3, T4 and T5, and the difference was statistically significant (P ＜0.05);(3 ) Values of the concentration of plasma NE of two groups compared in T1 ,T5 and T6, and the difference was statistically significant ( P ＜ 0. 05 ). Conclusion Cardiovascular response and stress response of orotracheal intubation using a videolaryngoscope is lower than using ordinary laryngoscope in snoring surgery.

Objeetive To explore a new therapeutic way of transurethral drugs perfusion combined with ultrashort wave on treating chronic bacteria prostatitis.Methods 241 cases with chronic bacteria prostatltis were randomly divided into two groups.the treatment group were treated with transurethral perfusion combined with ultrashort wave.the control group were treated with transurcthral drugs perfusion.Results Total effective rate in the treatment group was 85.9%.that of the control group was 36.7%.It had a significant difference between two groups(P＜0.01).Conclusion Transurethral drugs perfusion combined with ultrashort wave could promote the curative effect of antibiotic maximumly,so it is an effective method to treat chronic bacterial prostatitis.

Objective To study the role of serum C-reactive protein (CRP) ,supplement C3 and CA in sys-temic inflammatory response syndrome (SIRS) induced by acute cerebral infarction(ACI).Methods The levels of CRP,C3 and CA were measured by automatic immunoturbidimetry in 52 ACI cases accompanied with SIRS (SIRS group) ,50 cases of acute simple cerebral infarction(SACI group) and 46 normal cases (control group).Results The serum CRP, C3 ,and CA levels were significantly different among the three groups( F=720.6,580.8,94.1 ,P <0.01) ,the serum CRP levels in SIRS group were significantly higher than those in SACI group(P <0.01 ).The ser-um C3 and CA levels in SIRS were significantly lower than those in SACI group(P <0.01).With the diagnosis crite-rion items increasing, the serum CRP levels tended to be higher (t = 7.69 ,P < 0.01 ), and the serum C3, CA levels tended to be lower meeting SIRS diagnosis criterion numbers increasing respectively (t=10.68 and 10.53, P <0.01).Conclusion The serum ClIP levels are higher significantly and the serum levels of C3 and C4 are lower sig-nificantly when ACI progresses to SIRS.The serum CRP,C3,CA level changes can be used as an index for judging the progress of ACI progressed to SIRS.

OBJECTIVE:To provide reference for the effective integration of standardization strategy of traditional Chinese medicine (TCM) and intellectual property. METHODS:Through analyzing the conflict between standardization requirement of TCM and intellectual property system,the coordination between TCM standards and intellectual property especially the trade secret rights was explored. RESULTS:The information disclosure of TCM standards and intellectual property strategy especially protec-tion of TCM trade secrets faced confrontation and conflict in system and design. For the suggestions to solve it,one is to reconfirm the role and positioning of the government on the adaption of standardization in public law field;another is to establish coordina-tion principle of information disclosure and confidentiality in private law field,and achieve difference open and moderate open of information. CONCLUSIONS:The TCM standardization is not absolute,the pros and cons is the precondition to solve the conflict between the standardization strategy and trade secret system in TCM in terms of protection of information freedom and secret infor-mation.
