Objective To investigate the CT features of nodular or mass-like type pulmonary cryptococcosis(PC). Methods A total of 52 cases with nodular or mass-like type PC confirmed by pathological examinations at Fuzhou Pulmonary Hospital of Fujian from January 2008 to December 2012 were studied. Each patient underwent a breath-hold MSCT scan and contrast enhanced CT was performed in 19 patients. The data including lesion size, number, distribution, density, performance of enhanced CT scan and accompanying signs were analyzed. Each CT accompanying sign was compared between nodular lesions and mass-like lesions using χ2 test,continuous correction χ2 test or Fisher exact test. Results Of all the 52 patients, pulmonary cryptococcosis was consisted single nodules/masses (21 cases) and multiple of nodules/masses (31 cases). There were total 206 lesions with 172 nodules and 34 masses. The lesions were mainly found in lower lobe(73.3%, 151/206)and outer zone or subpleura(87.4%, 180/206)of lung. Plain CT scan showed the densities of most lesions were solid and uniform(74.7%, 154/206). A total of 95 lesions were detected in the 19 patients with contrast enhanced CT, in which 61 lesions (64.2%) showed homogeneous enhancement and 86 lesions (90.5%) showed moderate enhancement. Nodular or mass-like lesions accompanied by many CT signs including halo sign (59.2%, 122/206), air bronchogram (32.0%, 66/206), pulmonary cavity or vocule sign (15.0%, 31/206), lobulation sign (25.2%, 52/206), spicule sign (13.1%, 27/206), pleural indentation(7.8%, 16/206) and vascular cluster (1.9%, 4/206). Compared with mass-like lesions, lobulation sign was more frequently observed in nodular lesions(χ2=13.750, P=0.001), whereas air bronchogram and pulmonary cavity orvocule sign were less frequently observed(χ2=19.957, P=0.001; χ2=5.295, P=0.021, respectively). No significant statistically differences were detected in other CT signs between them (P>0.05). Conclusions PC lesions usually occur in right lung, lower lobe and close to the pleura. Halo sign and air bronchogram are the characteristic findings of CT manifestations in nodular or mass-like type PC.

BACKGROUND:Mechanical properties of the blood vessels include axial and radial tension which is important to guarantee the tissue perfusion and its pressure. OBJECTIVE:To test and analyze stretching and puncture parameters that can ful y characterize the performance of blood vessels, so as to predict the health condition of the vessels transplanted into recipients. METHODS:Mechanical properties as circumferential tension, axial tension and puncture were tested on the porcine aorta, and then pathological and staining analysis was done to explore whether freeze-dried vessels can withstand the blood pressure in al directions after transplanted into the body. RESULTS AND CONCLUSION:Specific trend on the curves of freeze-dried vessels during circumferential tension, axial tension and puncture process was closer to that of fresh vessel curves, suggesting that structural components and arrangement of the freeze-dried vessels were not changed greatly. Meanwhile, the microscopic observations of slice and tensile section were taken into account so that the reason was studied and explained for the mechanical properties of the experimental data and results. The macroscopic mechanical result was analyzed based on the change of microstructure. These findings indicate that the vacuum freeze-drying is a better method to maintain the performance of blood vessels.

Objective The value of pro-gastrin releasing peptide ( PGRP) which is the tumor marker of small cell lung canc-er has become a hot topic in recent years .The research was to build a new enzyme-linked immune sorbent assay ( ELISA) method ai-ming at detecting the concentration of PGRP in patients′serum. Methods We utilized synthetic PGRP epitopes for the screening of the monoclonal antibodies , labeled the screened monoclonal antibodies with horseradish peroxidase by modified sodium iodide method , and then established double antibody sandwich ELISA which could be used to detect the serum concentrations of PGRP in cancer pa -tients. Results We successfully screened E 12 mAb which could be served as the coating antibody and ED 1 mAb as the labeled anti-body.The standard antibody density range of new ELISA was 33 pg/mL~1.7 ×104 pg/mL.The comparison experiments between our method and the commercially available ELISA kit showed no significant difference ( P>0.05).The specificity of our method was 50%, and the sensitivity was 100%, while IBL kit was 92.2% and 100% respectively. Conclusion New ELISA can be used to detect the serum PGRP concentration in patients with small cell lung cancer .

Objective To compare the diagnostic efficiency of the thyroid imaging reporting and data system (TIRADS), the Bethesda system for reporting thyroid cytopathology(BSRTC) and BRAFV600E detection, and their combined use in the differentiation between benign and malignant thyroid nodules. Methods One hundred and twenty eight patients with 128 thyroid nodules who were scheduled for ultrasound-guided fine-needle aspiration biopsy (FNAB) were recruited for the study. All of them underwent ultrasound, fine-needle aspiration cytology(FNAC) examination, and BRAFV600E detection. TIRADS and BSRTC systems were adopted to judge the ultrasound and FNAC results. The receiver operating characteristic curve was established to assess the diagnostic value of each method. Results The sensitivity, specificity, and AUC of TIRADS were 74. 3%, 84. 5%, and 0. 794, respectively. BSRTC had higher specificity(98. 3%) and equal sensitivity compared to TIRADS. The sensitivity, specificity, and AUC of BRAFV600E detection were the highest ones among the three methods. Combinations of different methods could increase the diagnostic sensitivity and accuracy. The combination of FNAC and BRAFV600E detection significantly increased the diagnostic efficiency(AUC=0. 984), with sensitivity 98. 6% and specificity 98. 3%. Conclusions The diagnostic value of BRAFV600E detection in the differentiation of benign and malignant thyroid nodules is better than both TIRADS and BSRTC, and the combination of FNAC and BRAFV600E detection reaches the best diagnostic efficiency.

Objective To analyze the effects of dexmedetomidine(Dex) on levels of inflammatory cytokines in patients with acute exacerbation of chronic obstructive pulmonary disease (COPD). Methods From April 2015 to April 2017,94 patients with acute exacerbations of COPD who received mechanical ventilation in Wenling Hospital Affiliated to Wenzhou Medical College were randomly divided into two groups according to the digital table,with 47 cases in each group. Group A was given Dex,and group B was given midazolam. The levels of TNF - α,IL - 1, hs - CRP between the two groups were compared. Results There were no statistically significant differences in TNF - α,IL - 1,hs - CRP between the two group before treatment (all P > 0. 05). One day after treatment,the levels of TNF - α,IL -1,hs - CRP in group A were (92. 99 ± 15. 25)ng/ L,(68. 63 ± 14. 53)ng/ L,(15. 44 ± 4. 92)mg/ L, respectively,which in group B were (150. 63 ± 20. 78)ng/ L,(91. 13 ± 12. 58)ng/ L,(19. 35 ± 5. 17)mg/ L,respec-tively,there were statistically significant differences between the two groups(t = 2. 736,2. 503,2. 421,P = 0. 008, 0. 012,0. 015). Three days after treatment,the levels of TNF - α,IL - 1,hs - CRP in group A were (73. 37 ± 11. 01)ng/ L,(51. 52 ± 9. 16) ng/ L, (14. 82 ± 3. 29) mg/ L, respectively, which in group B were (123. 80 ± 19. 62)ng/ L,(73. 46 ± 17. 36) ng/ L, (18. 77 ± 4. 02 ) mg/ L, respectively, there were statistically significant differences between the two groups(t = 2. 184,2. 354,2. 098,P = 0. 031,0. 022,0. 039). Five days after treatment, the levels of TNF - α,IL - 1,hs - CRP in group A were (63. 54 ± 13. 06)ng/ L,(34. 04 ± 8. 13) ng/ L,(13. 84 ± 4. 13)mg/ L,respectively,which in group B were (76. 63 ±17. 39)ng/ L,(50. 66 ± 9. 17)ng/ L,(14. 27 ± 3. 95)mg/ L, respectively,there were statistically significant differences between the two groups( t = 1. 906,2. 082,1. 834,P =0. 067,0. 041,0. 081). Compared with group B,the ICU time in group A was significantly decreased[(9. 27 ± 1. 63) d vs. (7. 16 ± 1. 21)d,t = 2. 215,P = 0. 031](t = 2. 215,P = 0. 031). There was no statistically significant difference in the incidence rate of multiple organ dysfunction syndrome between the two groups at 5 days after treatment (χ2 =2. 286,P = 0. 132). Conclusion Dex can effectively inhibit inflammation cytokines of the mechanical ventilation COPD patients in acute exacerbation,and can reduce the ICU time.

After treatment with metformin, the acanthosis nigricans was significantly relieved, blood glucose was controlled satisfactorily, and the menstrual cycle was restored.

Allergic rhinitis (AR) is a global health problem that causes major illnesses and disabilities worldwide. Epidemiologic studies have demonstrated that the prevalence of AR has increased progressively over the last few decades in more developed countries and currently affects up to 40% of the population worldwide. Likewise, a rising trend of AR has also been observed over the last 2–3 decades in developing countries including China, with the prevalence of AR varying widely in these countries. A survey of self-reported AR over a 6-year period in the general Chinese adult population reported that the standardized prevalence of adult AR increased from 11.1% in 2005 to 17.6% in 2011. An increasing number of original articles and imporclinical trials on the epidemiology, pathophysiologic mechanisms, diagnosis, management and comorbidities of AR in Chinese subjects have been published in international peer-reviewed journals over the past 2 decades, and substantially added to our understanding of this disease as a global problem. Although guidelines for the diagnosis and treatment of AR in Chinese subjects have also been published, they have not been translated into English and therefore not generally accessible for reference to non-Chinese speaking international medical communities. Moreover, methods for the diagnosis and treatment of AR in China have not been standardized entirely and some patients are still treated according to regional preferences. Thus, the present guidelines have been developed by the Chinese Society of Allergy to be accessible to both national and international medical communities involved in the management of AR patients. These guidelines have been prepared in line with existing international guidelines to provide evidence-based recommendations for the diagnosis and management of AR in China.
