Objective To investigate the expression of Th1/Th2 cytoki nes in early symptomatic syphilitic lesions and its relationship with the sero-c onversion of RPR test in patients with syphilis. Methods The expression of Th1/Th2 cytokines in lesions from 30 patients with early symptomatic syphilis was i mmunohistochemically detected with ABC method. The serum titers of RPR test in t hese patients were measured in 1, 3, 6, 9 and 12 months after routine benzathine penicillin treatment. Results Among 10 cases of primary syphilis, the express ion of both Th1 and Th2 cytokines in the lesions was found in 9 cases, while onl y Th1 cytokine expression was observed in the remainder case; and the sero-conve rsion of RPR test occurred in all 10 cases during the follow-up period. Among 20 cases of secondary syphilis, Th1/Th2 cytokines expressed in the lesions in 16 c ases, and only Th2 cytokines expressed in 4 cases; and the sero-conversion of RP R test was found in 12 cases during the follow-up period. The expression of Th1 cytokines in early syphilitic lesions was positively correlated with the sero-co nversion of RPR test. The higher the expression of IFN- the more likely the s ero-conversion of RPR test. Conclusion The early activation and persistence of the expression of Th1 cytokines may play an important role in the clearance of pathogens.

Objective To investigate the variation of biomarker of coagulation, anti-coagulation, fibrinolysis in elderly critical patients and find out whether they are related to the disease severity. Methods Sixty-seven patients were no less than 60 years old. Eligible criteria: coincidence with the diagnostic criteria of systemic inflammatory response syndrome (SIRS) and APACHE Ⅱ score was no less than 10 scores. Blood sample was drawn from the venous for the test of biomarker (APTT, PT, TT, D-D, Fib, AT-Ⅲ , PC, PAI-1). According to the existent status,all the patients were divided into two groups:survival group (43 cases) and death group(24 cases) ,meanwhile,according to the diagnostic criteria of MODSE,all the patients were divided into MODSE group (30 cases) and non-MODSE group (37 cases). Results There were significant differences in APACHE Ⅱ score between MODSE group and non-MODSE group, survival group and death group [(25.83 ± 1.19) scores vs(18.1±20.73) scores and(18.81±0.72) scores vs(26.50 ± 1.42) scores](P <0.01). The PT and D-D in MODSE group anti death group were higher than those in non-MODSE group and survival group, the differences were significant (P <0.05),while the activity of AT-Ⅲand PC in MODSE group and death group were lower than those in non-MODSE group and survival group, the differences were significant (P <0.05). The PT,D-D and PAI-1 were positively correlated to APACHE Ⅱ score (related coefficients were 0.328, 0.308, 0.335,P <0.05). The AT-Ⅲ and PC were negatively correlated to APACHE Ⅱ score (related coefficients were -0.469, -0.559,P <0.01). Conclusions The abnormality of eoagnlation-fibfinolysis system exists in elderly critical patients. The extended PT, elevated D-D and PAI-1 ,descended PC and AT-Ⅲ are the hints of disease severity and poor prognosis.

Objective To study the effects of mild hypothermia (MH) on blood coagulation and cerebral microcirculation in rabbits after cardiopulmonary resuscitation (CPR). Method A total of 24 New Zealand rabbits were randomly (random number) divided equally into normothermic group (NT) and MH group. CPR model was established by ventricular fibrillation induced by using alternating current. The rabbits of NT group were observed for 12 h in room temperature after restoration of spontaneous circulation (ROSC). The mild hypothermia was induced in the rabbits of group MH by surface cooling after ROSC, and maintained for 12 h after the aimed low temperature reached. The PT (prothrombin time), APTT (activated partial thromboplastin time), INR (international normalized ratio of prothrombin), D-dimmer (DD) , blood platelet count (BPC) , anti-thrombin Ⅲ activity (AT-Ⅲ) and protein C activity (PC) were measured before CPR and 4 h, 8 h and 12 h after ROSC, and at the same time the cerebral microcirculation was measured by using PERIMED Multichannel Laser Doppler system. One-way ANOVA or Mann-Whitney rank was used to determine the statistical significance between two groups. LSD-t test was used for multiple comparisons,t test for comparisons of means between two independent samples, and Pearson correlation test for correlation analysis. Results The PT, APTT and INR showed a trend of gradually shortening during the course. The APTT in 12 h after ROSC was significantly shorter than that before CPR (23.32 ±5.19 vs. 29.53 ±5.10,P = 0.025), and the activity of AT- Ⅲ and PC were decreased significantly. Compared with the group NT,the PT, APTT and INR in group MH were increased significantly, while there were no differences in the activity of AT- Ⅲ, PC and D-D between two groups. The rates of cerebral microcirculation in group NT before CPR and 4 h, 8 h and 12 h after ROSC were 401.60 ± 11.76 mL/min, 258.86 ± 34. 58 mL/min,317.59 ± 23.36 mL/min and 371.98 ± 5.79 mL/min, respectively, and those in group MT were 398.18 ±12.91 mL/min, 336.19 ± 19.27 mL/min, 347.76 ± 13.80 mL/min and 383.78 ± 3.29 mL/min, respectively. There were significant differences between two groups at each interval after ROSC (4 h: t = - 6.025,df=16, P=0.000;8 h: t= -2.942, df=12, P=0.012;12 h: t= -3.959, df=8, P=0.004). The Pearson correlation test showed that the rate of cerebral microcirculation was positive correlated with APTT after ROSC (4 h:R =0.503,P=0.033;8 h:R=0. 565,P=0. 035;12 h:R=0. 774,P=0. 009), and was not correlated with the other blood coagulants. Conclusions The mild hypothermia led to the inhibition of blood coagulation and improved the cerebral microcirculation concomitantly, which may be one of the mechanism of cerebral protection.

Background:
Co-infections of the porcine reproductive and respiratory syndrome virus (PRRSV) and the Haemophilus parasuis (HPS) are severe in Chinese pigs, but the immune response genes against co-infected with 2 pathogens in the lungs have not been reported.
Objectives:
To understand the effect of PRRSV and/or HPS infection on the genes expression associated with lung immune function.
Methods:
The expression of the immune-related genes was analyzed using RNA-sequencing and bioinformatics. Differentially expressed genes (DEGs) were detected and identified by quantitative real-time polymerase chain reaction (qRT-PCR), immunohistochemistry (IHC) and western blotting assays.
Results:
All experimental pigs showed clinical symptoms and lung lesions. RNA-seq analysis showed that 922 DEGs in co-challenged pigs were more than in the HPS group (709 DEGs) and the PRRSV group (676 DEGs). Eleven DEGs validated by qRT-PCR were consistent with the RNA sequencing results. Eleven common Kyoto Encyclopedia of Genes and Genomes pathways related to infection and immune were found in single-infected and co-challenged pigs, including autophagy, cytokine-cytokine receptor interaction, and antigen processing and presentation, involving different DEGs. A model of immune response to infection with PRRSV and HPS was predicted among the DEGs in the co-challenged pigs. Dual oxidase 1 (DUOX1) and interleukin-21 (IL21) were detected by IHC and western blot and showed significant differences between the co-challenged pigs and the controls.
Conclusions
These findings elucidated the transcriptome changes in the lungs after PRRSV and/or HPS infections, providing ideas for further study to inhibit ROS production and promote pulmonary fibrosis caused by co-challenging with PRRSV and HPS.
