Objective To investigate the computed tomography (CT) features of solitary nodular invasive mucinous lung adenocarcinoma (IMA) in stage IA and establish its prediction model. Methods We included 53 lesions of 53 patients with stage-IA IMA and 141 control lesions of 141 patients with invasive non-mucinous lung adenocarcinoma (NIMA) that were confirmed by surgical pathology in our hospital from January 2017 to December 2019. Univariable analysis was used to compare the demographics and CT signs of the two groups. Multivariable logistic regression analysis was performed to determine the main factors influencing solitary nodular IMA. A risk score prediction model was constructed based on the regression coefficients of the main influencing factors. A receiver operating characteristic (ROC) curve was used to assess the performance of the model. Results The univariable analysis showed significant differences between the two groups in age, largest nodule diameter, tumor-lung interface, lobulation, spiculation, air-bronchogram or vacuole sign, vessel abnormalities (P < 0.05). The spiculation sign was different between the two groups, which was longer and softer in the IMA group while shorter and harder in the NIMA group. There was no significant difference in sex, nodule shape, or pleural retraction (P > 0.05), but irregular shapes were slightly more frequent in the IMA group. The multivariable logistic regression analysis showed that obscure tumor-lung interface (odds ratio (OR = 20.930, P < 0.05), air-bronchogram or vacuole sign (OR = 7.126, P < 0.05), spiculation sign (OR = 4.207, P < 0.05), and vessel abnormalities (OR = 0.147, P < 0.05) were the main influencing factors. The prediction model based on those factors’ regression coefficients had an area under the ROC curve of 0.829 (P < 0.05). Conclusion Compared with those with NIMA, patients with solitary nodular IMA in stage IA were older and more likely to have the CT features of obscure tumor-lung interface, air-bronchogram or vacuole sign, and longer and softer spiculation. Based on the regression coefficients of tumor-lung interface, air-bronchogram or vacuole sign, spiculation, and vessel abnormalities, the risk score prediction model showed good predictive performance for solitary nodular IMA.

OBJECTIVE To explore the influence of reusing and recycling times on the quality of ethanol recovered from ethanol deposition solution of aqueous extract of Lonicerae Japonicae Flos. METHODS The ethanol in five consecutive batches of Lonicerae Japonicae Flos water extract ethanol deposition was recovered by vacuum distillation. The impurities in five batches of recovered ethanol and the recovered ethanol when partial coking caused by temperature runaway were qualitatively analyzed by headspace solid phase micro extraction combined with gas chromatography-mass spectrometry(HS-SPME/GC-MS), and the ultraviolet absorbance of each batch of recovered ethanol was also analyzed. RESULTS Styrene was the only impurity in the first and second batch of recovered ethanol; there were five impurities in the third and fourth batch of recovered ethanol; the number of impurities in the fifth batch of recovered ethanol increases to 17. When partial coking was occurred, the exogenous impurities in the recovered ethanol increased dramatically to forty-one, and there were harmful substances such as ninhydrin and naphthalene. The ultraviolet absorbance of the third to fifth batch of recovered ethanol exceed the upper limit stipulated in the second part of Chinese Pharmacopoeia, 2020 Edition. While the ultraviolet absorbance of the recovered ethanol when partial coking takes place exceeds the standard of the pharmacopoeia greatly. CONCLUSION The recovered ethanol should be treated after being reused two times, so that its ultraviolet absorbance level and impurity type are equivalent to that of fresh ethanol before it can be used again. The method provides reference for the quality control and compliance use of recovered ethanol.

To explore the role of progesterone in the pathogenesis and development of hemangioma in nude mice.
Methods: The hemangioma model was established. Progesterone was injected intramuscularly at different doses (0.2, 0.4, and 0.8 mg/d) for one week. Camellia oil (0.4 mL/d) was injected intramuscularly as control. The size of hemangioma was observed dynamically. The subcutaneous implants were harvested on the 14th and 28th days. The expression of vascular endothelial growth factor in the tumor tissues were evaluated using immunohistochemistry and microvessel density (MVD) was counted under the microscope.
Results: On the 14th day, the expression of vascular endothelial growth factor (P<0.01 and P<0.05, respectively) was higher, the volume of tumors (All P<0.01) and MVD (All P<0.01) were greater in the high-dose progesterone group than those in the control and low-dose progesterone group. On the 28th day, there was no significant difference in the volume of tumors among 4 groups (P>0.05). The expression of vascular endothelial growth factor (P<0.01) was lower, and MVD (All P<0.05) were less in the middle-dose and high-dose progesterone group than those in the control and low-dose progesterone group.
Conclusion: Progesterone promotes angiogenesis via upregulation of vascular endothelial growth factor expression, promotion of hemangiomas proliferation, suggesting that excessive progesterone supplementation may be one of the initial factors for early hemangioma formation.

To explore the proportion for facial aesthetics that may be recognized by the potential group who will do plastic surgery in the future.
Methods: We measured the celebrity photos, who were born before 1980 recognizable by the people over 40 years old or by high school students. The proportions for facial aesthetics recognizable by these two generations were obtained and compared.
Results: Compared the new generation of male celebrities with the older generation of male celebrities, the difference was statistically significant by the independent samples t test (t=-2.502, P<0.05), while other ratios were not statistically significant (P>0.05). Compared the new generation of female celebrities with the older generation of female celebrities, the difference was statistically significant by the independent samples t test. The ratios between inter-canthic diameter and eyeslit breadth, mouth breadth and eyeslit breadth, stirnhohe and 1/3 of the physiognomic facial height, nasal height and 1/3 of the physiognomic facial height were significantly different (P<0.05), while other ratios were not significantly different (P>0.05).
Conclusion: The young new generation loves more larger eyeslit breadth for men, while a larger eyeslit breadth, smaller bizygomatic breadth and sharper chin for women.

Chinese Journal of Tissue Engineering Research 2014;(38):6216-6221
BACKGROUND:Heat shock proteins have unique biological characteristics, and exploration of such proteins expressed in the myocardium under exercise stress has important value.
OBJECTIVE:To investigate the studies about the expression of myocardial heat shock proteins under stress condition, and analyze the expression characteristics of myocardial heat shock proteins under different stress conditions.
METHODA computer-based online retrieval was performed to find articles about the production, classification and function of heat shock proteins, as wel as the expression of myocardial heat shock proteins published from January 1991 to January 2014 in PubMed database and Wanfang databases. The key words were“heat shock protein;myocardium;exercise stress”in English and Chinese. Final y 48 relevant articles were summarized.
RESULTS AND CONCLUSION:Heat shock proteins have the immune synergy effect. Researches show that, exercise training triggers the expression of myocardial heat shock protein. Acute exercise stress leads to a variety of physiological and biochemical changes, accordingly myocardial heat shock protein wil make the corresponding expression and protect myocardial cells. Low-intensity exercise can increase the expression level of heat shock protein 72, and inhibit cardiomyocyte apoptosis. High-intensity exercise reduces the expression of heat shock protein 72, which can not effectively inhibit cardiomyocyte apoptosis and is not conducive to the myocardial protective effect. The expression of heat shock protein under moderate-intensity exercise remains controversial. Exercise-induced expression of heat shock protein may have protection effect against damage induced by exercise, moderate exercise activities play an important role in enhancing myocardial function and preventing myocardial injury.
