ObjectiveTo evaluate the advantages and disadvantages of endoscopic thyroidectomy by the breast approach. MethodsFrom August 2002 to April 2003, sixty single thyroid nodule patients were divided into 2 groups randomly. Group 1 (30 patients) received endoscopic thyroidectomy(ET) by the breast approach. The other 30 patients underwent conventional thyroidectomy(CT). Preoperative diagnosis,operative time,operative cost,postoperative pain,complications,and cosmetic result between the 2 groups were compared. ResultsOperative time was 118.0?34.3 minutes for ET group and 80.0?23.5 minutes for CT group( P

OBJECTIVETo investigate the impact of occupational stress on serum monoamine neurotransmitters in nurses.

METHODSA total of 131 nurses were included as study subjects by stratified cluster sampling. The occupational health information collection system (based on the Internet of things) was used to measure occupational stress. Serum levels of monoamine neurotransmitters were also measured.

RESULTSEpinephrine (E) was negatively correlated with superior support (P < 0.05) and colleague support (P < 0.05). Negative correlation was also found between dopamine (DA) and job prospect (P < 0.05). Level of 5-hydroxytryptamine was negatively correlated with promotion opportunities (P < 0.05). Norepinephrine (NE), E, and DA were all negatively correlated with work satisfaction (P < 0.05) and positively correlated with daily stress (P < 0.01). NE and E were negatively correlated with sufficient confidence (P < 0.05) and positively correlated with physical complaints (P < 0.01). There was a negative correlation between NE and psychological satisfaction (P < 0.05).

CONCLUSIONOccupational stress in nurses is correlated with serum monoamine neurotransmitters, and it may affect serum levels of monoamine neurotransmitters to a certain extent.

With the aggravation of global aging process and the strengthening of patients’ awareness of rights, the realization of the elderly and end-of-life patients’ right to know and autonomy, and the satisfaction of physical and mental needs have become new indicators to measure social development. Advance care plan focuses on the discussion process of patients, their families and medical staff on end-of-life medical decisions and death intentions, which greatly promotes the development concept of palliative care and optimal death. To promote this process in the context of traditional Chinese culture, it is also necessary to combine with the local family concept and collectivism. Therefore, this paper introduced a sustainable social support system involving multiple subjects such as families, communities, social workers, and legal workers, with a view to benefiting the elderly and end-of-life patients.

Objective To compare the clinicopathological characteristics between primary and contralateral cancers in patients with metachronous bilateral breast cancer (MBBC) who carried a BRCA1/2 germline pathogenic variant. Methods A total of 496 BRCA1/2 carriers with primary unilateral breast cancer were included (196 with BRCA1 and 300 with BRCA2). Clinicopathological information of patients was collected, and the median follow-up for the entire cohort was 10.4 years (0.4-20.8 years). Results Among all patients, 31 (15.8%) of the 196 BRCA1 carriers and 49 (16.3%) of the 300 BRCA2 carriers had MBBC, respectively. Among the 31 BRCA1 carriers who developed MBBC, the proportion of triple-negative breast cancer (TNBC) in primary cancer and contralateral cancer was 61.3% and 67.7%, respectively. If the primary cancer of BRCA1-mutated MBBC was TNBC, the probability of the contralateral breast cancer with TNBC was 89.5% (17/19), which was significantly higher than that if the primary cancer was non-TNBC (33.3%, 4/12) (P=0.004). Among the 49 BRCA2 carriers who developed MBBC, the predominant molecular phenotype of the primary and contralateral cancers was HR+ & HER2- (77.6% and 67.3%, respectively; P=0.53). Conclusion Approximately 60% of BRCA1 carriers exhibit TNBC. If a BRCA1 carrier with a TNBC primary breast cancer had an MBBC, the probability of the contralateral breast cancer being TNBC phenotype is almost 89.5%.

AIM: To investigate the effect of Rho kinase inhibitor Y-27632 on acute liver injury in sepsis. METHODS: Thirty-two healthy adult male SD rats were randomly divided into sham operation group (Sham group), sham operation+Y-27632 group (Sham+Y group), cecal ligation and perforation group (CLP group) and CLP+Y-27632 group (CLP+Y-27632 group), 8 animals in each group. The rat sepsis model was established by the CLP method, and the rat was euthanized 24 hours after the model was established, and the serum and liver tissue were collected. Hematoxylin-eosin (HE) staining was used to observe the pathological changes in the liver tissue of the rats in each group; Western Blot was used to detect the expressions of ROCK1 and downstream NF-κB proteins in the liver tissue of the rats in each group; immunohistochemical method The expression of ROCK1 protein in liver tissue of rats was detected; enzyme-linked immunosorbent assay (ELISA) method was used to detect the levels of serum liver function indexes ALT and AST, and the changes of IL-18, IL-10 and GSH contents in liver tissue homogenate. RESULTS: Compared with the Sham group, there was no significant change in the histopathology of the liver in the Sham+Y group. In the CLP group, the arrangement of hepatocytes was disordered, with a large number of inflammatory cells infiltrating. Compared with the Sham group, the expression of ROCK1 protein in the CLP and CLP+Y groups was increased (P<0.05); compared with the CLP group, the ROCK1 protein expression in the CLP+Y group was decreased (P<0.05). Compared with the Sham group, the expression of NF-κB protein in the CLP and CLP+Y groups increased (P<0.05); compared with the CLP group, the NF-κB protein expression in the CLP+Y group decreased (P<0.05); A small amount of expression was found in the liver Sham group, and a large amount was expressed in the CLP group and CLP+Y group; compared with the Sham group, the serum ALT and AST levels in the CLP and CLP+Y groups were increased (P<0.05). The levels of ALT and AST in +Y group decreased (P<0.05). Compared with the Sham group, the contents of IL-18 in the liver tissue homogenate of the CLP and CLP+Y groups increased (P<0.05), while the contents of IL-10 and GSH in the liver tissue homogenate of the CLP group decreased (P<0.05). The changes of IL-10 and GSH in the group were similar (P>0.05); compared with the CLP group, the content of IL-18 in the CLP+Y group was decreased (P<0.05), and the content of IL-10 and GSH was increased (P<0.05). CONCLUSION: Rho kinase inhibitor can alleviate acute liver injury in septic rats, which may be related to inhibiting the expression of ROCK1 and NF-κB proteins, reducing the inflammatory response of liver tissue, and reducing the level of liver oxidative stress.
