Objective To investigate the correlation between the mutation in serum lipoprotein-associated phospholipase A2(Lp-PLA2) Ile198Thr, Val279Phe and cerebral infarction in Chinese Han population of Jiangsu Province. Methods One hundred fifty patients with cerebral infarction and 100 healthy controls in Chinese Han population of Jiangsu Province were recruited. The correlation between Val279Phe and Ilel98Thr mutation in Lp-PLA2 gene and cerebral infarction was analyzed using polymerase chain reaction and denaturing high performance liquid chromatography. Results The Val279Phe genotype and the mutant allele frequency in the cerebral infarction group were significantly higher than those in the control group (χ2 were 6. 31and 5. 32, respectively, all P <0. 05), and there was no significant difference between the Ile198Thr genotype and the mutant allele frequency in the control group (χ2 were 0. 039 and 0. 037, respectively, all P >0. 05). Conclusions The Val279Phe mutation in Lp-PLA2 gene may be a genetic risk factor for cerebral infarction in Chinese Han population of Jiangsu Province.

Objective To evaluate the value of serum procalcitonin (PCT) in antibiotics used for the treatment of acute exacerbation of asthma. Method From February 2007 to July 2009, a total of 158 patients with asthma were randomly (random number) assigned to PCT group ( n = 77) or to control group ( n = 81 ). The PCT levels of all patients were measured. On the bases of routine treatment, the employment of antibiotics in control group was determined by the guidebook, and patients in the PCT group were treated with antibiotics guided by the levels of serum PCT. The antibiotics treatment was employed as PCT level >0.25 ng/mL, and was not employed as PCT level < 0.25 ng/mL. The rates of antibioties employment were observed. Results The rate of antibiotics employment in PCT group (45.4%) was lower than that of the control group (77.8%) (x2 = 17.15,P =0.000). Conclusions PCT could be used safely as guidance of antibiotics employment for the treatment of patients with acute exacerbation of asthma, leading to appropriate use of antibiotcs.

Abstract: Objective To study the characteristics and diagnostic efficacy of Rose-Bengal plate agglutination test (RBPT), standard-tube agglutination test (SAT) and enzyme-linked immunosorbent assay (ELISA) in the diagnosis of brucellosis. Methods A total of 489 suspected brucellosis patients with complete records, who admitted to Xing'anmeng People's Hospital from March 2020 to May 2021, were selected as the subjects. The diagnostic value of SAT, RBPT and ELISA for brucellosis was analyzed with exposure history + clinical symptoms + serological test/brucellosis isolation and culture as the gold standard. Results Of the 489 suspected patients, 183 (37.42%) were diagnosed with brucellosis, while 234 (47.85%), 148 (30.27%) and 195 (39.88%) were positive by RBPT, ELISA and SAT, respectively. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of RBPT in the diagnosis of brucellosis were 95.08%, 80.39%, 74.36%, 96.47%, and 85.89%, respectively; the values of the above parameters for ELISA were 78.69%, 98.69%, 97.30%, 88.56%, and 91.21%, respectively; those values of SAT were 98.36%, 95.10%, 92.31%, 98.98%, and 96.32%, respectively. The sensitivity of RBPT was significantly higher than ELISA, but the specificity and accuracy were significantly lower than ELISA (all P<0.05). The sensitivity and accuracy of SAT diagnosis were significantly higher than ELISA, but the specificity was significantly lower than ELISA (all P<0.05). There was no significant difference between SAT and RBPT in the sensitivity of diagnosis, but the specificity and accuracy were significantly higher than those of RBPT (P<0.05). Conclusion RBPT and SAT have high sensitivity in diagnosis of brucellosis, while ELISA has high specificity in diagnosis. RBPT with high sensitivity and convenient operation can be used for primary screening in field detection, and then the other two methods can be used for rechecking, so as to further improve the efficiency and accuracy of diagnosis of brucellosis.

Objective To investigate the effects of external fixator with dynamic device under low frequency and controlled micromovement on the callus calcification and mechanical property of healing bone.MethodsForty-five sheep were performed transverse osteotomy with a gap of 2 mm on the mid-shafts of both tibias,and the hind limbs were fixed with unilateral external fixators connected to a controlled micromovement device.Ten days after osteotomy,one hind limb of each sheep was randomly selected for micromovement(30 min/d).According to different micromovement frequencies,the sheep were randomly divided into 3 groups: 0.5 Hz group,1 Hz group and 5 Hz group(n=15).The amplitude of micromovement was 0.25 mm and the micromovement stopped by the end of the fourth week postoperation.The other hind limb of each sheep was served as control group without micromovement.Morphometry of callus was done at the end of 4,6 and 9 weeks after osteotomy.Bone formation velocity,bone mineral density and biomechanical properties were compared at the end of 9 weeks.Results The areas of mineralized bone and osteoid in different miromovement groups were larger than that of control group at the end of 4,6 weeks postoperation(P

AlM: To explore the expression and significance of cysteine- rich 61 ( CCN1/Cyr61 ) in oxygen - induced retinal neovascularization ( RNV) of mice and study the inhibition effect of CCN1 specific siRNA on RNV.
METHODS:Two hundred healthy C57BL/6J mice were chosen and randomly divided into control group, hyperxia group, hyperxia control group and CCN1 treated group, with 50 mice in each group. The hyperxia control group was treated with vector plasmids by intravitreal injection. The CCN1 treated group received CCN1 siRNA recombinant plasmids by intravitreal injection. Adenosine diphosphate-ase ( ADPase) stained retina flat-mounts was performed to assess the retinal vascular profiles, HE staining was applied to count the number of vascular endothelial cell nuclei breaking through the internal limiting membrane, protein and mRNA level expression of CCN1 were measured by immunohistochemistry, Western blot and RT-PCR.
RESULTS: There were large nonperfusion area and a large number of vascular endothelial cell nuclei breaking through the internal limiting membrane ( 25. 25 ± 1. 26;23. 12 ± 1. 16 ) in the hyperxia group and the hyperxia control group. Regions of nonperfusion and vascular endothelial cell nuclei (8. 47±1. 15) were decreased in the CCN1 treated group compared to the hyperxia group and the hyperxia control group. Compared with the control group, there were high protein and mRNA expression of CCN1 in the hyperxia group and the hyperxia control group. The expression of CCN1 protein and mRNA were decreased in the CCN1 treated group compared with the hyperxia group and hyperxia control group (all P<0. 05).
CONCLUSlON: The abnormal expression of CCN1 has close relation with RNV. The development of RNV can be markedly inhibited by RNA interference targeting CCN1, which, we believe, will provide new molecular targets and a rationale for clinical developing new strategy for ROP therapy.
