3.Multiple ultrasonographic indexes in diagnosis of unruptured ectopic pregnancy
Chinese Journal of Medical Imaging Technology 2010;26(2):307-309
Objective To evaluate the methods for improving diagnostic ratio of unruptured ectopic pregnancy with ultrasonography. Methods A total of 139 patients of small adnexal cysts with thick wall were predicted respectively with sonographic indexes. All patients (61 with unruptured ectopic pregnancy and 78 with small corpusluteum) were confirmed postoperatively or with long-term follow up, and the results were compared. Results The diagnostic sensitivity of with hyperecho or isoecho compared with endometrium, hyperecho compared with ovarian tissue, adnexal cyst without small follicle around was 86.89%, 93.44% and 96.72%, and the specificity of three predictors was 93.59%, 85.90% and 70.51%, respectively. Two sonographic indexes together had a sensitivity of 98.36% and a specificity of 94.87% for diagnosing ectopic pregnancy. Conclusion Observing the relation of adnexal cyst and ovarian and the echogenic of cyst wall are specific and sensitive for the diagnosis of ectopic pregnancy.

Journal of Clinical Otorhinolaryngology Head and Neck Surgery 2015;29(16):1467-1471
OBJECTIVE:
To observe the effect of formaldehyde inhalation on the allergic rhinitis mice model.
METHOD:
Forty-eight male BALB/C mice in six experimental group were exposure to (A) saline control; (B) Der p1; (C) formaldehyde (3.0 mg/m3); (D) Derp1 + formaldehyde (1.5 mg/m3); (E) Der p1 + formaldehyde (3.0 mg/M3); (F) Der p1+ formaldehyde (6.0 mg/m3). The concentrations of IL-4, IL-10 and IFN-γ in the peripheral serum were measured by enzyme-linked immunosorbent assay(ELISA). Nasal mucosal inflammation was evaluated by HE staining. Result: Formaldehyde exposure could increase the number of allergic rhinitis mice with sneezing and rubbing nose. The levels of IL-4 and IL-10 in group B, D, E and F were higher than that ingroup A (P < 0.05). Compared with the group C, the group D, E and F could effectively increase serum IL-4 and IL-10. The concentration of IL-4 in group E and F was higher than that of group B, while the group C was lower (P < 0.05). The concentration of IL-10 in group D, E and F was higher than that in group B (P < 0.05). The expression of IFN-γ in group B, D, E and F was lower than that in group A. While, the IFN-γ expression in group B was lower than that of group C and higher than that in group F (P < 0.05). Moreover, the concentration of IFN-γ in group D, E and F was lower compared with group C (P < 0.05). The nasal mucosa HE staining showed that the density of EOS increased simultaneously in formaldehyde exposure allergic rhinitis groups.
CONCLUSION
The study showed that formaldehyde exposure can promote Th2 cytokines and eosinophil infiltration and then aggravate the allergic rhinitis symptoms.

8. The regulatory mechanism of autophagy in prostate cancer
Tumor 2012;32(12):1035-1038
Autophagy is a metabolic process whereby intracellular substance is degraded in lysosomes of eukaryotic cells, which plays an important role in cell survival, growth, differentiation and maintenance of cellular homeostasis. The regulatory mechanism by which autophagy contributes to tumorigenesis is complex and also exhibits the effects of a double-blade sword. At the earlier stage of the neoplastic process, autophagy can inhibit the formation of tumor by preventing the accumulation of damaged organelles and accelerating the protein degradation process. However, in the process of tumor development, autophagy can help tumor cells survive under the conditions of hypoxia and nutrient deprivation by degrading and recycling intracellular substances. Prostate cancer is the most common malignant tumor in male genital system. Rrecent studies show that autophagy is closely related to tumorigenesis, and therefore the molecular mechanism of autophagy has been the focus of research. This review focuses on the regulatory mechanism of autophagy in prostate cancer, hoping to provide a theoretical basis of autophagy for the treatment of prostate cancer. Copyright © 2012 by TUMOR.

Objective To explore the most convenient and valid tool for screening mental disorders among servicemen. Methods Soldiers and officers stationed at Guilin were enrolled for the study. They were first examined with the Symptom Check-list 90 (SCL-90), Cornell Medicine Index (M-R)[CMI(M-R)], University Student Personality Inventory (UPI) and WHO neurosis screening schedule respectively. Then they were subjected clinical interview and examination individually, and clinical diagnosis of mental disorder was made according to CCMD-3 standard. The validity of each questionnaire was evaluated by using Criterion-related Validity. Results The sensitivity of WHO neurosis screening schedule was found to be 100%, and the specificity was 92.1%. SCL-90 and CMI (M-R) yielded similar results, their sensitivity was found to be 46.9% and 43.4%, and the specificity to be 86.1% and 78.9%, respectively. The sensitivity of UPI was found to be 83.1% and the specificity 46.1%. Conclusion The WHO neurosis screening schedule is the best in both sensitivity and specificity of validity, but its practice is time-consuming and laborious, which limits its application. SCL-90 and CMI (M-R) are imperfect in sensitivity of validity, and they cannot screen out the mental disorder in more than a half of the subjects. In a group test, they can hardly serve as a screening tool. UPI can screen out most of the mental disorder, and its sensitivity of validity reaches 83.1%. Additionally, the UPI questionnaire contains fake-test items, which could retest those who were missed due to untruly or not conscientiously answer the questionnaires. An acceptable way to obtain a true screening test is to give the individuals a propaganda of mental health and explain the questionnaires for 30 minutes before the test, which helps the examinee to understand the procedure and accept the questionnaires, so that the results of the test could be more reliable. In conclusion, UPI is a valuable screening tool to be recommended.

Abstract: Objective To explore the correlation between levels of hypersensitive C-reactive protein (hs-CRP) and procalcitonin (PCT) in serum and alveolar fluid and severity of disease in children with lobar pneumonia. Methods A total of 112 children diagnosed with lobar pneumonia from September 2020 to September 2021 were selected as the research subjects. The levels of hs-CRP and PCT in serum and alveolar fluid were detected by double antibody sandwich enzyme-linked immunosorbent assay (ELISA). The children were divided into severe group (clinical pulmonary infection score, CPIS≥6 points) and mild group (CPIS<6 points) according to the severity of disease, and further classified into good prognosis group (cured, improved) and poor prognosis group (uncured) according to their treatment outcomes. The correlation of levels of hs-CRP and PCT in serum and alveolar fluid with disease severity in children and their predictive value on prognosis were analyzed. Results The levels of serum hs-CRP and PCT in severe group were (17.73±3.26) μg/L and (8.59±1.84) μg/L, which were significantly higher than corresponding (12.58±3.09) μg/L, and (5.62±1.59) μg/L in mild group (P<0.05); the levels of hs-CRP and PCT in alveolar fluid in severe group were (21.25±4.18) μg/L and (8.71±1.54) μg/L, which were significantly higher than corresponding (13.79±2.76) μg/L and (5.38±1.69) μg/L in mild group (P<0.05). The levels of hs-CRP and PCT in serum and alveolar fluid were positively correlated with CPIS scores (r=0.398, 0.441; 0.475, 0.586, P<0.05). The levels of hs-CRP and PCT in serum in poor prognosis group were (20.09±4.20) μg/L and (13.35±2.91) μg/L, which were significantly higher corresponding (8.75±2.19) μg/L and (6.28±1.31) μg/L in good prognosis group (P<0.05). The levels of hs-CRP and PCT in alveolar fluid were (23.70±4.29) μg/L and (10.73±2.04) μg/L, which were higher than corresponding (15.08±3.56) μg/L and (5.79±1.10) μg/L in poor prognosis group (P<0.05). There was no significant difference in AUC between combined detection of serum indicators and combined detection of alveolar perfusion fluid indicators in predicting the prognosis of children with lobar pneumonia (P>0.05). Conclusions The levels of hs-CRP and PCT in serum and alveolar fluid of children with lobar pneumonia are significantly increased and positively correlated with the severity of disease. However, the predictive value of the combined detection of serum indicators and combined detection of alveolar perfusion fluid indicators for the prognosis of children with lobar pneumonia is comparable.
