International Journal of Laboratory Medicine 2015;(3):310-312
Objective To explore the association between the tumor necrosis factor receptor-associated factor 1(TRAF1)/com-plement component 5(C5)single nucleotide polymorphism and rheumatoid arthritis patients.Methods Two groups of people were included in the study:300 rheumatoid arthritis(RA)patients(RA group)and 300 healthy individuals(control group).Real-time PCR was used to test the single nucleotide polymorphisms rs3761847 and rs10818488 of TRAF1/C5.Results There was no signifi-cant difference (P >0.05)of TRAF1/C5 rs3761847 and rs10818488 polymorphism between the two groups.The linkage disequilib-rium analysis results showed that there was strong linkage disequilibrium between rs3761847 and rs10818488.For the RF,anti-CCP and anti-Sa negative RA patients,the difference in the frequency of A allele of rs3761847 between the RA patients and matched con-trols was statistically significant(P =0.001,OR =0.57,95%CI :0.41 -0.79;P =0.001,OR =0.51,95%CI :0.35 -0.76;P =0.02,OR=0.72,95%CI :0.55-0.94).Significant difference for the frequency of G allele of rs10818488 between RF positive RA patients and control groups was observed(P =0.01,OR=1.40,95%CI :1.09-1.81).Conclusion TRAF1/C5 gene polymorphism may not associate with susceptibility of RA patients in Han population in Guizhou.

This study was aimed to observe the protective effect of extract from Rhizoma A nemones Raddeanae (RAR) on hepatic fibrosis induced by porcine serum in rats. A total of 68 SD rats were randomly divided into 5 groups, which were the normal group, model group, RAR group, extraction of RAR (EXRAR) group, Fu-Zheng Hua-Y u(FZHY) group. Each rat was intraperitoneally injected with 0.5~0.6 ml of porcine serum twice a week for 15 suc-cessive weeks to establish liver fibrosis model. Intragastric administration was given after the model was successfully established. The FZHY group was given FZHY capsule (0.525 g·kg-1). The RAR group was given RAR decoction (0.7 g·kg-1). The EXRAR group was given EXRAR (0.071 g·kg-1). The model group and normal group were given e-qual amount of physiological saline. The medication was given once a day. And the treatment course was 8 weeks. At the end of the 23th week, rats were sacrificed. Contents of SOD and MDA in blood serum were assayed. The protein expressions of α-SMA and TGF-β1 in liver tissues were detected by SABC. The results showed that compared with the model group, content of MDA decreased in the EXRAR group, RAR group and FZHY group (P<0.05), and content of SOD increased obviously (P<0.05). In the model group, expression of α-SMA and TGF-β1 increased, with dark brown dyeing and diffusion area. Expression area and strength of the FZHY group, RAR group, and EXRAR group were ob-viously weak with tasteless interval dyeing and no formation of typical pseudolobule in comparison with the model group. The color rendering index showed that compared with the model group, the protein expression of α-SMA and TGF-β1 decreased obviously in liver tissues of the FZHY group, EXRAR group, and RAR group (P< 0.05). It was concluded that RAR and its extract had a good antifibrosis effect. And the EXRAR had basically the same antifibrosis effect as RAR. It was assumed that the possible mechanism was related with the inhibiting of hepatic stellate cell (HSC) activation and the expression of TGF-β1 as well as the resisting of lipid peroxidation.

Objective:To investigate the diagnostic value of different detection methods for Mycobacterium tuberculosis in bronchoalveolar lavage fluid (BALF) from patients with pulmonary tuberculosis.Methods:BALF from l00 patients in Changsha Central Hospital from January 2013 to December 2015 was collected.Among 100 patients,65 cases were clinically diagnosed as tuberculosis,and 35 cases served as control.BALF smear method,polymerase chain reaction (PCR) and membrane reverse dot blot (RDB) were used for synchronous detection of Mycobacterium tuberculosis.Results:The positive rates by BALF smear method,PCR and RDB were 43.08%,73.84% and 92.31%,respectively (P<0.05).Sensitivity,specificity,accuracy,and negative predictive value for BALF smear were 43.08%,88.57%,59.00%,and 45.59%,respectively;for PCR were 73.85%,100%,83.00%,and 67.31%,respectively;for RDB were 92.31%,100.00%,95.00%,and 87.50%,respectively.Conclusion:The technique of membrane RDB can not only accurately diagnose Mycobacterium tuberculosis,but also can rapidly and easily identify the resistance of Mycobacterium tuberculosis to streptomycin (SM),rifampicin (RFP) and isoniazid (INH) genotypes.It possesses high clinical value.

Objective To explore the application effect of clinical pathway in clinical teaching for on -the-job training nursing staff in neurosurgery department .Methods Thirty-six nurses who accepted on-the-job training from March 2009 to December 2010 were selected as control group , and thirty-six nurses who accepted on-the-job training from March 2011 to December 2012 were selected as observation group .The traditional teaching method was used in the control group , and the teaching method of clinical pathway was used in the observation group .All nurses were trained for three months , who took the relevant exams on theory and operation at the end of each month , in order to evaluate their learning quality at each stage of learning .Nurse ’ s satisfaction with teaching was evaluated at the end of the on-the-job training .Results The score of theoretical knowledge, nursing operations and comprehensive quality ability was (93.51 ±4.61), (93.46 ±2.94) and (91.57 ±3.71) in the observation group, respectively, and (91.07 ±3.88), (91.29 ±2.87) and (88.44 ± 4.28) in the control group, respectively, and the differences were statistically significant (t=2.435, 3.173, 3.319, respectively;P<0.05).Nurse’s satisfaction with teaching was 100.00%(36/36) in the observation group and 83.33%( 30/36 ) in the control group, with statistically significant difference ( P <0.05 ). Conclusions Application of clinical pathway in clinical teaching for on-the-job training nursing staff can improve the quality of clinical teaching , mobilize the initiative and enthusiasm of teachers and nurses , and improve nurse ’ s satisfaction with teaching .
