ObjectiveTo investigate the effect of Wudan pill on the polarization of macrophages in the rat model of endometriosis （EMT） with cold congeal and blood stasis syndrome based on p38 mitogen-activated protein kinases （p38 MAPK）. MethodFemale SD rats with regular motility cycles were selected and randomly divided into sham-operated group， model group， Wudan pill high， medium， and low-dose groups （2.4， 1.2， and 0.6 g⋅kg^-1）， Chinese patent medicine group， and western medicine group by the random number table method. The method of ice water bath + autologous endometrial transplantation was used to establish the rat model of EMT with cold congeal and blood stasis， and the rats were executed after 4 weeks of continuous drug administration to collect materials. Expression levels of serum tumor necrosis factor-α （TNF-α）， interleukin-1β （IL-1β）， IL-4， and transforming growth factor-β （TGF-β） were determined by enzyme-linked immunosorbent assay （ELISA） to assess inflammation. The real-time quantitative polymerase chain reaction （Real-time PCR） was performed to determine the inducible nitric oxide synthase （iNOS）， TNF-α， arginase 1 （Arg1）， and human mannose receptor （CD206） transcriptional levels to evaluate macrophage polarization. Western blot （WB） and immunofluorescence （IF） assays were used to determine the protein expression levels of iNOS and Arg1 to corroborate macrophage polarization. WB and Real-time PCR were used to determine the protein expression levels of the p38 MAPK pathway. ResultAs compared with sham-operated group， the levels of serum TNF-α， IL-1β， TGF-β， and IL-4 of rats in the model group were significantly higher （P<0.05）. In the model group， the protein levels of iNOS， TNF-α， p-p38 MAPK， and phosphorylated-extracellular signal-regulated kinase （p-ERK） in endothelial tissues were significantly higher， the mRNA levels of iNOS， TNF-α， MAPK， and ERK were significantly higher， and the mRNA and protein expression levels of Arg1 and CD206 were significantly lower （P<0.05， P<0.01）. The number of iNOS positive cells in endothelial tissues was significantly increased， and the number of Arg1 positive cells in endothelial tissues in the model group was significantly decreased （P<0.05， P<0.01）. As compared with the model group， the expression of TNF-α， IL-1β， TGF-β， and IL-4 in each administration group was reduced to different degrees， which was especially significant in the Wudan pill high and medium-dose groups and the western medicine group （P<0.05）. The protein expression levels of iNOS， TNF-α， p-p38 MAPK， and p-ERK in endometrial tissues of rats in the Wudan pill high and medium-dose groups， the Chinese patent medicine group， and the western medicine group were significantly lower， the mRNA expression levels of iNOS， TNF-α， MAPK， and ERK were significantly lower， and the protein expression levels of Arg1 and CD206 were significantly higher （P<0.05， P<0.01）. The number of iNOS positive cells in endometrial tissues of rats was significantly decreased in the Wudan pill high and medium-dose groups， the Chinese patent medicine group， and the western medicine group， whereas the number of Arg1 positive cells was increased （P<0.05， P<0.01）. The low， medium， and high doses of Wudan pill were dose-dependent， and the efficacy of the Wudan pill high-dose group was similar to that of the western medicine group. ConclusionWudan pill reduces the inflammatory response in rat model of EMT with cold congeal and blood stasis syndrome and decreases expression levels of TNF-α， IL-1β， IL-4， and TGF-β， thereby prompting polarization of macrophages from M1 to M2 type. The mechanism is presumedly related to p38 MAPK signaling pathway.

OBJECTIVETo investigate the value of C-reactive protein (CRP) on transplantation day in predicting early post-transplant infections and outcomes of allogeneic hematopoietic stem cell transplantation (allo-HSCT).

METHODSWe retrospectively analyzed the clinical data of 78 recipients undergoing allo-HSCT. The clinical reference value of CRP on transplantation day was determined, and its sensitivity and specificity for diagnosing bacteremia was analyzed using receiver-operating characteristic curve (ROC). The incidence of transplant-related complications, overall survival, and relapse rate of the patients were analyzed with respect to the CRP level.

RESULTSThe clinical reference value of CRP for diagnosing bacteremia was 23.3 mg/L (AUC=0.735 [95% CI: 0.623-0.848], P=0.001), which had a diagnostic sensitivity and specificity of 0.793 and 0.592, respectively. Compared with the patients with low CRP levels, the patients with high CRP levels tended to have delayed neutrophil reconstitution and platelet engraftment by 0.71 days (P=0.237) and 4.09 days (P=0.048), respectively, and had a significantly higher incidence of bacteremia (17.1% vs 53.5%, P=0.001) and CMV viremia (37.1% vs 72.1%, P=0.003) within 100 days following the transplantation; the incidences of EBV viremia, pulmonary invasive fungal infection, or acute graft versus host disease (aGVHD) showed no significant difference between the two groups (41.9% vs 22.9%, P=0.094; 14.0% vs 5.7%, P=0.285; 51.2% vs 45.7, P=0.656, respectively). During the follow-up for a median of 318 (7-773) days in high-CRP group and for 299 (78-747) days in low-CRP group, the high-CRP group showed a significantly lower 2-year overall survival than the low-CRP group (42.5% vs 78.4%, P=0.022), and tended to have a higher 2-year cumulative relapse rate (52.3% vs 19.8%, P=0.235). Logistic multivariate analysis identified a high CRP level on transplantation day as the independent risk factor for post-transplant bacteremia within 100 days (OR=5.090 [95% CI: 1.115 -23.229], P=0.036).

CONCLUSIONA high CRP level on transplantation day can be indicative of a high risk of early post-transplant bacteremia and CMV viremia and also a poor prognosis following allo-HSCT.

Objective To discuss the clinical value of immunofecal occult blood test in screening of colorectal cancer and its precancerous lesions in a large series of health checkup population. Methods Colorectal cancer and its precancerous lesions in 5919 subjects undergoing health checkup in our hospital were screened out by using immunofecal occult blood test from July 2006 to June 2007; positive cases with the test were subjected to colorectal endoscopy or X-ray barium enema examination. Relevant results were analyzed in combination with clinical and pathological data. Results Positive result was obtained in 314 out of the 5919 subjects undergoing health checkup with immunofecal occult blood test; the positive rate was 5.30%. 241 cases(76.75% )of them accepted colorectal endoscopic examination and 23 cases(7.32%) accepted X-ray barium enema examination. The total follow up rate was 84.08% with 50 cases out of contact. After excluding the cases out of cantact, 16 cases of colorectal cancer were found morbidity 2.37‰ including 8(50.00% )cases of Dukes A,7 cases (43.75%)of Dukes B and 1 case of Dukes C (6 .25%).The detection rate of colorectal cancer with postive imunofecal occult blood test was 6.06% (16/264). 94 cases (16.01‰) of adenomatous polyps were found including 55 cases (58.51%) of tubular adenoma, 23 cases (24.47% )of villiform- tubular adenoma and 16 cases(17.02%) of villfform adenoma. Among these cases 55 (58.51%)were solitary and 39(41.49%) multiple. In addition, 6 cases of ulcerative colitis in active phase were found. Altogether 116 (43.94%)of the 264 cases with positive immunofecal blood test and not out of contact were found to have colorectal cancer or its precancerous lesions. Conclusion Immunofecal occult blood test is suitable for screening of colorectal cancer and its precancerous lesions in large series of population. Colorectal cancer and its precancerous lesions may be found in relatively early phase and be eradicated in curable stage, thus to reduce the morbidity and mortality.
