Purpose: Human epidermal growth factor receptor 2 (HER2)-low breast cancer has the potential to emerge as a distinct subtype. Several studies have compared the differences between HER2-low and HER2-0 breast cancers, but no consensus has been reached.Additionally, a biomarker to predict pathological complete response (pCR) rates in patients with HER2-low breast cancer remains to be identified. Methods: We collected data from 777 patients across three centers, stratifying them into HER2-low and HER2-0 groups. We compared differences in survival and pCR rates between the two groups and investigated potential biomarkers that could reliably predict pCR. Results: The study found that patients with HER2-0 breast cancer had higher pCR rates compared to patients with HER2-low tumors (289 patients [30.1%] vs. 475 patients [18.1%], p < 0.0001). Survival analysis showed no significant advantage for HER2-low tumors over HER2-0 breast cancers. Binary logistic analysis revealed that androgen receptor (AR) expression predicts poorer pCR rates in both the overall patient group and the HER2-0 breast cancer group (overall patients: odds ratio [OR], 0.479; 95% confidence interval [CI], 0.250–0.917; p = 0.026 and HER2-0 patients: OR, 0.267; 95% CI, 0.080–0.892; p = 0.032). In contrast, programmed death ligand 1 (PD-L1) expression was associated with more favorable pCR rates in the overall patient group (OR, 3.199; 95% CI, 1.020–10.037; p = 0.046). Conclusion There is currently insufficient evidence to classify HER2-low breast cancer as a distinct subtype. Our study revealed that AR expression, along with negative PD-L1 expression, contributes to lower pCR rates.

In the era of the new healthcare reform, high-quality cost accounting can effectively enhance the business performance of public hospitals. Compared with single-campus hospitals, the cost accounting of multi-campus hospitals is faced with greater complexity and challenges. The authors analyzed cost accounting problems found in the latter, namely the lack of top-level design in the construction of a fine multi-campus cost accounting system, difficulty of reasonable collection and allocation of various costs, lack of strong information support, outdated research methods used in item cost accounting among others, as well as their causes. On such basis, the authors put forward countermeasures for high-quality cost accounting in multi-campus hospitals, for the purpose of fully leveraging the leadership of cost control in the high-quality development of public hospitals.

Objective:To systematically analyze the clinical features of severe fever with thrombocytopenia syndrome (SFTS) and to provide evidence for the prevention and treatment of SFTS.Methods:Relevant studies of SFTS from six databases, including China National Knowledge Infrastructure, Wanfang Database, Chongqing VIP, PubMed, Cochrane Library and Embase from January 2009 to May 2019 were systematically searched and identified. The literatures were screened and the data of patients′ epidemiology, clinical manifestations, laboratory examinations and prognosis were obtained. Revman 5.2 software was used for meta analysis.Results:Sixty-eight Chinese literatures and fourteen English literatures encompassing 6 780 patients with SFTS were included in the final analysis. Of these patients, 845 cases (12.46%) died. SFTS mostly occurred in mountainous and hilly areas, and farmers (3 637 cases) were the usual victims. The onset season was mostly in summer and the peak was from May to August each year. There were 1 434 patients had a clear history of tick bites, and 21 cases were human-to-human transmitted.There were 6 071 cases (89.54%) presented with fever, 5 407 cases (79.75%) presented with fatigue, 3 140 cases (46.31%) presented with muscle soreness, and 2 300 cases (33.92%) presented with chills.Using random effects model for meta analysis, the levels of creatine kinase (CK) (mean difference ( MD)=500.40, 95% confidence interval ( CI) 380.51-620.28, P<0.01) and lactic acid dehydrogenase (LDH)( MD=442.81, 95% CI 152.85-732.78, P=0.003) in severe patients were both higher than those in mild patients, and the difference were both statistically significant. The risk of death increased in patients aged>60 years( MD=8.19, 95% CI 4.03-12.36, P<0.01). The levels of CK( MD=530.92, 95% CI 29.27-1 032.56, P=0.040), LDH( MD=609.28, 95% CI 80.25-1 138.31, P=0.020), urea nitrogen ( MD=4.67, 95% CI 3.05-6.30, P<0.01) and creatinine ( MD=43.05, 95% CI 23.49-62.62, P<0.01) of patients in the death group were all higher than those in the survival group. The differences were all statistically significant. Conclusions:During the course of SFTS, the patients may show impaired blood system, heart, liver and kidney functions with high mortality. Clinicians should timely monitor the changes of blood routine, myocardial enzyme spectrum, liver and kidney functions and other indicators, so as to find cardiovascular and other system complications as early as possible. Timely treatment could not only reduce liver, heart and other organ injuries, but also reduce mortality.

Objective: To analyze the prevalence of severe fever with thrombocytopenia syndrome virus(SFTSV)infection in Zhoushan island of Zhejiang province and the duration of serum positive IgG antibody in patients infected with SFTSV. Methods: One thousand one hundred and twenty-two healthy people from Zhoushan island of Zhejiang province were recruited for cross-sectional study in August 2019, including 641 from non-epidemic areas and 481 from epidemic areas. The serum SFTSV-IgG antibody was detected by enzyme-linked immunosorbent assay (ELISA), and the positive rates of SFTSV-IgG antibody were compared between people from the epidemic areas and non epidemic areas. Meanwhile, the antibody titer of SFTSV-IgG in 19 patients confirmed between July 2011 and June 2018 was detected by indirect ELISA. SPSS 17.0 software was used to analyze data. Results: The positive rate of SFTSV-IgG antibody was 1.5% (7/481) in the epidemic area, which was higher than that in the non-epidemic area (0/641) (χ²=7.187, P<0.01). The positive rates of SFTSV-IgG antibody in 2019 were lower than those in the epidemic area (11.7%) and non-epidemic area (2.5%) in 2013 (χ²=22.556 and 10.352, both P<0.01). The serum SFTSV-IgG antibody of 18 patients with previous infection was still positive, and the longest one lasted for 8 years. Conclusions There is a SFTSV latent infection in population from epidemic area of Zhoushan island. The SFTSV-IgG antibody can last for a long time in patients with SFTS and it may have certain protective effect.
