Verification of Volume Similarity Between Unilateral Mammary Gland and Autologous Omentum in Adult Women by Measuring Cylinder Method.

OBJECTIVE: To verify the volume similarity between unilateral mammary gland and autologous omentum in adult females. METHODS: A total of 63 patients diagnosed with stage 0-II breast cancer and partial non-lactating multi-fistula mastitis in the breast surgery department of Inner Mongolia Xing'an League People's Hospital from 2007 to 2020 were enrolled in the study, including 52 cases of stage 0-II breast cancer and 11 cases of non-lactating multi-fistula mastitis. The volume of the resected mammary gland and the omentum were measured by a "soft tissue measuring cylinder" and recorded. The appearance of the reconstructed breast was compared with that of the healthy side. The correlation between unilateral mammary gland volume and autologous omentum volume was analyzed by linear regression. RESULTS: Valid data were obtained for 60 cases. Affected breast size, curve, texture, nipple, and inframammary fold after omentum breast reconstruction were similar and symmetrical to those of the unaffected side. Postoperative complications occurred in most patients; the majority of these (76.67%) involved numbness of the nipple, and other complications were few. Patient satisfaction with postoperative appearance, feel, and movement of the breast, as well as total treatment costs, was over 75.0%. Linear regression analysis indicates a linear relationship between subcutaneous gland volume (x) and autologous omentum volume (y): y = 0.9847x - 1.2132, R 2 = 0.9742. CONCLUSION: Only when the dissociated pedicled omentum is completely obtained under laparoscopy can the whole subcutaneous residual cavity of the mammary gland be filled to the same volume. This study verifies that the volume of the unilateral mammary gland is similar to that of the autologous omentum in adult females.

The Prevalence of Compulsive Buying and Hoarding Behaviours in Emerging, Early, and Middle Adulthood: Multicentre Epidemiological Analysis of Non-clinical Chinese Samples.

Behavioural addictions, such as compulsive buying (CB) and hoarding, are increasingly recognised in the current psychiatric nosology, particularly in developed countries. The prevalence of these disorders may not be static but possibly altered across different age groups. However, studies on this area are rare, and only few have focused on Chinese population. This epidemiological study employs population-based cross-sectional design and collects data in two regions, i.e., Hong Kong and Mainland China. A self-reported questionnaire is constructed based on carefully validated Chinese versions of Richmond Compulsive Buying Scale and Hoarding Rating Scale. A total of 2,439 valid samples are collected and divided into three age groups, i.e., emerging, early and middle adulthood. CB and hoarding behaviours have displayed an inverted u-shaped pattern across the above age groups. In addition, the strength of correlation between the two compulsive behaviours is consistent and maintained across different age groups. These results suggest that the compulsive behaviours vary among different stages of adulthood in major cities in China. This newly discovered pattern of compulsive disorders in Chinese population is different from those in American and European populations.

The Relationship Between Compulsive Buying and Hoarding in China: A Multicenter Study.

There is no previous research that has explored the correlation between compulsive buying and hoarding in the Chinese population. This study aims to determine the relationship between compulsive buying and hoarding in a sample of the Chinese population comprising participants from mainland China (emerging economy) and Hong Kong (developed economy). Self-reported measures consisting of demographic questions, the Chinese version of the Hoarding Rating Scale (CHRS), and Richmond Compulsive Buying Scale-Traditional Chinese (RCBS-TC) were administered to participants. After data collection, common method biases were precluded. The RCBS-TC and CHRS were validated by confirmatory factor analysis and found correlated by Pearson correlation coefficient. The RCBS-TC and CHRS demonstrated satisfactory levels of internal consistency (Cronbach's α = 0.872 and 0.828, respectively). A three-factor model, including hoarding, obsessive-compulsive, and impulse control disorders, was obtained through Confirmatory Factor Analysis (CFA) with the satisfactory fit for the total sample from Hong Kong and mainland China. A significant correlation was found between RCBS-TC and CHRS (r = 0.473). Findings also showed that 14% of the participants exhibited compulsive buying behavior. This study provides sufficient proof of the reliability and validity of RCBS-TC and CHRS. Their relationship was explored based on two sets of samples from different regions in Asia, which contributes more applicability in a cross-cultural context.

[The expression and significance of signal regulatory protein a1 in autoimmune hepatitis].

OBJECTIVE: To observe the expression change of signal regulatory protein alpha1 (SIRPalpha1) in autoimmune hepatitis (AIH) and approach the relationship between SIRPalpha1 and the extent of inflammation. METHODS: Immunohistochemistry is used to detect the expression of SIRPalpha1 in the paraffin section preparations of 33 AIH and 10 normal hepatic tissue. RESULTS: SIRPalpha1 is positive or weakly positive expressed in AIH. The staining is localized in the cytoplasm of Kupffer cells in the hepatic sinusoid with focal distribution. It is negative in normal hepatic tissue. In light AIH, it is negative or weakly positive expressed with a 36.4 percent of the positive rate (4/11). The positive or strong positive expression is found in the moderate AIH with an 84.2 percent of the positive rate(16/19). There is statistical significance between both light AIH, moderate AIH and severe AIH (P less than 0.001) and moderate AIH and light AIH (P less than 0.001). There is no statistical significance between both light AIH and severe AIH (P = 0.145 ) and moderate AIH and severe AIH (P = 0.084). CONCLUSIONS: As a negative regulatory factor, the expression of SIRPalpha1 in hepatic sinusoid Kupffer cells is some associated with the extent of AIH.
