Objective To assess the value and clinical applicability of non-treponemal antigen serologic test and Treponema pallidum antigen serologic test in the diagnosis of congenital syphilis. Methods Totally,7800 newborns were collected from the out-patient and in-patient department. Toluidine red unheated serum test (TRUST) was conducted to quantitatively detect non-treponemal antibodies and Treponema pallidum particle agglutination assay (TPPA) to qualitatively detect specific treponemal antibodies in these subjects. The results of first serology test for syphilis were assessed for neonates with confirmed congenital syphilis. The sensitivity and specificity in the diagnosis of congenital syphilis were compared between TPPA and TRUST.Results Of the 7800 newborns undergoing syphilis serology testa, 60 were positive for TPPA and TRUST,including 15 cases of congenital syphilis, 47 were positive for TPPA but negative for TRUST, including 5 cases of congenital syphilis. The sensitivity and specificity were 75% (5/20) and 99.41% (7734/7780) respectively for TRUST in the diagnosis of congenital syphilis, 100% (20/20) and 98.88% (7693/7780) respectively for TPPA. Conclusion TPPA seems more applicable than TRUST to the screening for congenital syphilis.

The pharmacokinetics and tissue distributions of the novel paclitaxel microemulsion based on the L-OH lipid complex made in our laboratory were studied in this article with the commercial paclitaxel injection in cremophor as reference preparation by injected intravenously with single dose of 5 mg x kg(-1) in rats. LC-MS/MS method was used to determine the drug concentration in plasma and calculate the pharmacokinetic parameters. [3H]-paclitaxel was used to reveal the tissue distributions of different organs in 0.5 h, 3 h, 24 h and 120 h. The results indicated that the AUC of the emulsion group descended to 42.55%, with the CLz and Vz increased by 2.27 times and 3.81 times respectively. Tissue distribution results revealed that the emulsion showed a significantly increase in liver and spleen with a peak concentration up to 5 times; a slightly increase was observed in lung with no statistical differences; a significantly decrease in heart, kidney, gastrointestinal tract, bone marrow, aorta, thymus, pancreas, fat, muscle, skin, seminal vesicle, reproductive organs and brain with a drop of 40%-80%. These results indicated that paclitaxel microemulsion based on L-OH lipid complexes can remarkably reduced the blood exposure, accelerate plasma clearance rate and increase distribution volume. The fact that paclitaxel microemulsion tended to be uptake by reticuloendothelial system (RES) contributed to the target in liver, spleen and lung, and help to reduce the toxicity in blood, heart, kidney and gastrointestinal tract.

Objective To investigate the clinical values of postoperative aerobic exercise and psychological intervention in patients with breast cancer after operation.Methods One hundred patients with breast cancer admitted to our hospital were prospectively studied.All patients underwent modified radical mastectomy and were randomly assigned into observation group (50 cases)and control group (50 cases).The patients in the observation group were treated with aerobic exercise and psychological intervention,and the health education was given in the control group. The 3 -month postoperative self -rating anxiety scale score,self -rating depression scale score,shoulder mobility, degree of limb edema and 6 -month postoperative health related quality of life (SF -36)of the two groups were observed.Results There were no significant differences between the two groups in preoperative self -rating anxiety scale score,self -rating depression scale score,degree of limb edema and health related quality of life (all P >0.05).However,the self -rating anxiety scale score of the observation group three months after operation significantly decreased compared with the control group[(40.94 ±9.20)points vs.(45.84 ±8.79)points,t =2.722,P =0.008];self -rating anxiety scale score significantly decreased[(40.18 ±9.96)points vs.(45.28 ±8.67)points,t =2.730, P =0.008];the degree of limb edema was significantly reduced[(10.00 ±6.27)mL vs.(18.52 ±7.20)mL,t =6.313,P =0.000].The health related quality of life 6 months after operation was significantly improved[(78.70 ± 8.85)points vs.(72.02 ±9.76)points,t =3.584,P =0.001 ].Compared with the control group,the shoulder flexion,extension,abduction,external rotation and internal rotation of the observational group were significantly increased at 3 months after operation (all P <0.05 ).Conclusion Postoperative rehabilitation and psychological intervention contribute to the rapid recovery in patients with breast cancer after operation.

Objective To investigate the association of chlamydia pneumoniae infection with ankylosing spondylitis (AS).MethodsSerum samples were obtained from 33 AS patients and 22 healthy controls.Enzyme-linked immunosorbent assay (ELISA) was applied to mearsure serum anti-Chlamydia pneumoniae antibodies (IgM/IgG),while immunofluorescence assay (IFA) was used to detect Chlamydia pneumoniae LPS antigen,and polymerase chain reaction (PCR) was used to amplify Chlamydia pneumoniae DNA in peripheral blood cells. Immunohistochemistical technique was applied to examine Chlamydia pneumoniae LPS antigen in synovial tissue from another 9 AS patients who received total hip replacement and 13 patients with comminuted femoral fractures.ResultsThe positive rates of Chlamydia pneumoniae IgM,LPS antigen and chlamydia pneumoniae DNA were higher in AS patients than those in healthy controls (78.8％ vs 22.7％,x2 =16.867,P =0.000; 66.7％ vs 31.8％,x2 =6.431,P =0.011; 33.3％ vs 9.1％,x2 =4.298,P =0.038).Chlamydia pneumoniae DNA positive rate was correlated with erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels (Z =-2.774 and -2.829,P =0.004).In synovial tissues,chlamydial LPS-containing inflammatory cells were observed in 77.8％(7/9) AS patients,while those in fracture patients was 30.8％ ( 4/13 ) ( P =0.08 ).Conclusion Chlamydia pneumoniae infection is common in blood circulation and joint cavity of AS patients and may be associated with the pathogenesis of AS.

Objective To analyze a population of cells on the right lower lateral of monocyte population in forward scatter/side scatter(FSC/SSC)(X-axis/Y-axis)scatterplot of peripheral blood leucocyte by flow cytometry(FCM)and its influencing factors.Methods The type of cells were identified based on cluster of differentiation antigen(CD)by FCM.The impact of temperature,hemolysin concentration,and incubation time was evaluated.Blood lipid tests were performed to observe the relation between them by statistical methods.Results (1) Phenotypo of this population of cells on the right lower lateral of monocytes in FSc/SSC scatterplot is CD+45 CD+13 CD+14 CD3- CD-19 ,which was the same as monocyte cells:(2)The monocytes in FSC/SSC scatterplot shifted to left side after using haemolysin;(3)The monocytes showed less resistance to antihemolysin in 37℃ than that in 220C:There were more monocytes shifting to left side with the increase of haemolysis time:(4)The swarming ratio of monocytes in patients (31.5%,40/126) Was higher than it in normal controls (5.1%,5/98)(x2=22.74,P<0.01);(5)The levels of total serum cholesterol(TC),triglyeride(TG),low density lipoprotein cholesterol(LDL-C), apoprotein B100(Apo B100) in patients with swarming monocytes were lower than that in the patients without swarming monocytes,(P<0.05).There was no statistical significance between the two groups with respect to levels of total bilirubin(TBIL),albumin(Alb),hish density lipoprotein cholesterol(HDL-C),apoprotein A I(Apo A I),lipoprotein(Lpa).Conclusions Peripheral blood monocytes can be divided in two groups in FSC/SSC scatterplot when analyzed with FCM.The presence of this population of cell Was related to resistance to hemolysin.It can be influenced by haemolysis time and incubation temperature.Therefore,the effect of swarming monocytes and abnormal cell membrane should be taken into consideration when the markers and function of monocytes are detected by FCM.

Objective To observe and investigate the efficacy and safety of combining with intrathecal injection of vancomycin and dexamethasone based on intravenous meropenem for treating refractory purulent meningitis in children.Methods Ninety children cases of refractory purulent meningitis from June 2014 to March 2015 were randomized into the observation group (45 cases) and control group (45 cases) according to the random number table method.The control group was given intravenous meropenem therapy,on this basis the observation group was added with intrathecal injection of vancomycin and dexamethasone.The changes of serum inflammatory markers and clinical efficacies after 7 d treatment were compared between the two groups,and the incidence rate of sequelae in the two groups were recorded after 3-months follow up.Results The descend ranges of TNF-a,CRP and PCT after 7 d treatment in the observation group were (87.3±21.8)pg/mL,(47.9±10.7)mg/L and (348.9J67.3)pg/mL,which were significantly higher than (61.5±18.5)pg/mL,(33.0± 7.9)mg/L,(263.7 ± 61.5)pg/mL in the control group(P＜0.05).There was statistically significant difference in clinical efficacy between the two groups (Z=2.086,P=0.037),the total effective rate in the observation group was 93.3 ％,which was higher than 82.2 ％ in the control group (x2 =2.589,P =0.108);the average treatment duration in the observation group was(12.8 ± 3.9)d,which was significantly less than (16.7 ± 4.7)d in the control group,the difference was statistically significant(t=4.216,P＜0.01).There were no statistically significant differences in the incidence rate of adverse drug reactions and sequelae between the two groups (P＞0.05).Conclusion With intrathecal injection of vancomycin and dexamethasone based on intravenous meropenem therapy for treating purulent meningitis,can further inhibit the inflammatory reaction,and increases clinical efficacy without significantly increasing adverse drug reactions.
