Objective To establish and analyze the morphological parameters of the oocysts of Cryptosporidium muris for defining their morphological change. Methods Oocysts were collected from KM mice(immunodepressed by dexamethasone for 10 days) and examined with modified acid-fast staining. Images of 1 190 oocysts were acquired by photograph system. The length, width, perimeter, area and equivalent diameter of the oocysts were obtained by computer digital image processing system and analyzed by SPSS software (Version 11.0). Result The average length of the oocysts was 5.93 ?m, ranging from 3.36 ?m to 8.51 ?m in 95% confidence interval of them. The average width was 4.96 ?m, ranging from 3.26 ?m to 6.66 ?m in 95% confidence interval of them. The average perimeter was 18.03 ?m and the average area was 16.08 ?m2. Conclusion Data obtained from the computer system are objective and precise, offering scientific foundation for measuring the oocysts and for identifying Cryptosporidium spp.[

Results: Higher incidence and more serious degree of arteries lesions occurred in diabetes mellitus than those in control group ( P 40 years old than in group ≤40 years old in diabetes mellitus ( P

Raman spectroscopy is an optical technology based on the theory of Raman scattering, which is generally used in the research of medical and biological science. Raman spectroscopy can be used to detect the molecular structures and components of proteins, lipids, DNA, and other biological molecules, and provide substantial information about molecules. Thus, Raman spectroscopy is generally considered a "molecular fingerprint", and it has exceptional advantages in medical research. Moreover, this technique can reflect the changes in molecular structures and detect the alterations of chemical constituents in the samples. Raman spectroscopy, given its high sensitivity and specificity in the detection of the biological samples, has been successfully used to detect and diagnose diseases in numerous sites, such as skin, oral mucosa, breast, head, and neck. In this paper, we introduce the application of Raman spectroscopy in stomatology by conducting a review of the literature.

The abnormal expression of MUC15, a novel cell membrane-associated mucin, has been reported to predict poor survival in several cancers. The aim of the present study was to examine the expression of MUC15 in glioma and its correlation with clinicopathological features, including the survival of patients with glioma. The mRNA expression level of MUC15 was determined by RT-PCR, quantitative RT-PCR (RT-qPCR) and Western blotting in seven normal brain tissues and seven glioma tissues, respectively. The protein expression level of MUC15 was immunohistochemically detected in paraffin-embedded samples of 317 glioma tissues and 115 noncancerous brain tissues. The association of MUC15 expression levels with the clinicopathologic features and the prognosis was analyzed. The results showed that both mRNA and protein levels of MUC15 were significantly increased in glioma as compared with those in noncancerous brain tissue. Moreover, MUC15 overexpression was positively correlated with the advanced clinical stages of glioam patients (P<0.01). Furthermore, MUC15 expression levels were significantly correlated with the progression of glioma (P<0.001). Survival analysis indicated that glioma patients with higher MUC15 expression had a significantly shorter overall and 5-year survival time than those with low MUC15 expression. Multivariate analysis suggested that MUC15 overexpression was an independent factor for prognosis (hazard risk: 3.216; P=0.009). It was concluded that MUC15 is overexpressed in glioma tissues. Its overexpression correlates with tumor progression and it is a potentially unfavorable prognostic factor for patients with glioma.

Objective To observe the curative effects of Ginkgo dipyridolum injection in the treatment of acute cerebral infarction and its influence on blood rheology and fibrinogen content.Methods 96 patients with acute cerebral infarction were randomly divided into two groups.39 patients in Ginkgo dipyridolum group were treated with 20 ml Ginkgo dipyridolum injection plus 500 ml saline intravenously,once a day.57 patients in control group were treated with Xuesaitong injection 10 ml plus 500 ml saline intravenously,once a day.All treatment lasted for 14 days.The score of neurological deficit was evaluated to assess the clinical efficiency,the changes of indexes of blood rheology,fibrinogen content and skull CT in the two groups were observed before and after treatment.Results Total effective rate(94.9%)in the Ginkgo dipyridolum group was signifcantly higher than that in the control group(78.9%)(P

Objective:To explore the value of pre- and postoperative red cell distribution width-to-lymphocyte count ratio (RLR) in predicting the disease-free survival (DFS) for non-metastatic colorectal cancer patients.Methods:The data of 108 patients pathologically diagnosed with non-metastatic colorectal adenocarcinoma after surgery from December 2012 to January 2020 in Hainan Hospital of PLA General Hospital were retrospectively analyzed. RLR was calculated and its differences in patients with varied clinicopathological characteristics were analyzed. The receiver operating characteristics (ROC) curve was applied to analyze the value of pre- and postoperative RLR in predicting DFS of patients, and the cut-off value was determined by Youden index. DFS of patients with different stratification stratified by a cut-off value of RLR was analyzed by using Kaplan-Meier method followed by log-rank test. Cox proportional hazards model was used to make univariate and multivariate analysis.Results:Youden index of pre- and postoperative RLR in predicting DFS was 8.86%, 9.15%; based on the above index, the patients were divided into the preoperative RLR<8.86% group (73 cases) and preoperative RLR≥8.86% group (35 cases), postoperative RLR<9.15% group (48 cases) and postoperative RLR≥9.15% group (60 cases). According to ROC curve, the area under the curve (AUC) of preoperative RLR in predicating DFS was 0.66 (95% CI 0.55-0.77, P = 0.01), and AUC of postoperative RLR in predicating DFS was 0.62 (95% CI 0.51-0.74, P = 0.04). Pre- and postoperative RLR cut-off values were used to predict 3-year DFS rate of patients with the sensitivity of 51.60% and 71.00%, respectively, and the specificity of 76.60% and 50.60%, respectively. Kaplan-Meier analysis showed that patients in preoperative RLR<8.86% group had a better DFS compared with those in preoperative RLR≥8.86% group ( χ2 = 7.35, P < 0.01); there was no statistical difference in DFS between postoperative RLR<9.15% group and postoperative RLR≥9.15% group ( χ2 = 3.69, P = 0.06). Preoperative RLR was an independent affecting factor for DFS of patients ( HR = 1.13, 95% CI 1.04-1.22, P <0.01). Conclusions:Pre- and postoperative RLR could be useful in predicating 3-year DFS for patients with non-metastatic colorectal cancer. Preoperative RLR is an independent affecting factor for DFS, and the patients with low RLR have a better prognosis.

Objective To observe the sub-clinical inflammation and insulin resistance (IR) in patients with cerebral infarction(CI). Methods The levels of serum C-reactive protein (CRP),interleukin-6 (IL-6),fasting insulin (Fins),fasting plasma glucose (FPG),blood lipids and blood pressure were measured in 114 patients with CI (CI group). The insulin sensitivity index (ISI) was observed and the correlation between ISI and indexes of inflammation were analysed. The results were compared with 70 patients without CI(control group). Results (1) The levels of serum CRP [(2.73?0.87) mg/L]and IL-6[(0.14?0.03) ng/ml] in CI group were significantly higher and ISI(-4.31?0.53) was significantly lower compared with control group[CRP(1.63?0.93) mg/L,IL-6(0.12?0.03) ng/ml,ISI(-3.92?0.43)] ( all P8.2 mg/L was significantly lower than that in the patients with the CRP≤8.2 mg/L (-4.18?0.54)(P
