METHODS: Immunostaining of HER2 was performed and scored on a scale of 0-3 in 957 consecutive GC cases, according to the revised scoring criteria of HercepTest TM as used in the ToGA trial. Correlations between HER2 expression and clinicopathologic variables of proximal (n = 513) and distal (n = 444) GC were investigated. RESULTS: Our results showed that HER2 expression was significantly higher in the proximal than in distal GC (P < 0.05). Overall, HER2 expression was significantly higher in male patients (P < 0.01), the Lauren intestinal type (P < 0.001), low-grade (P < 0.001) and pM1 (P < 0.01) diseases, respectively. There was a significant difference in HER2 expression among some pTNM stages (P < 0.05). In contrast, HER2 expression in the distal GC was significantly higher in male patients (P < 0.001), low-grade histology (P < 0.001), the Lauren intestinal type(P < 0.001), and pM1 (P < 0.001). In the proximal GC, however, higher HER2 expression scores were observed only in tumors with low-grade histology (P < 0.001) and the Lauren intestinal type (P < 0.001). CONCLUSION: HER2 over-expression in GC of Chinese patients was significantly more common in proximal than in distal GC, and significantly correlated with the Lauren intestinal type and low-grade histology in both proximal and distal GC, and with pM1 disease and male gender in distal GC.展开更多

The difficulty of COP diagnosis is that the clinical features and the radiological findings are nonspecific. The pathological hallmark of organizing pneumonia (OP) needs to be confirmed. It can also occur in a variety of other interstitial pneumonia, infectious diseases, vasculitis, and so on. To increase the pathological reliability, larger and more tissue samples are required. According to the current classification of interstitial lung disease and guidelines, the surgical lung biopsy is recommended and is considered to be the best way of obtaining a representative lung specimen However, the invasive diagnostic procedures require general anesthesia and also increase the morbidity and mortality risks; therefore, only few patients undergo such biopsy. Thus, safer and more acceptable methods for identifying COP are urgently needed.展开更多

Therefore, more and more rare diseases and early stages of lung diseases were found. Here, we reported a case who presented as multiple ground glass nodules incidentally found in chest CT scan who had been suspected as synchronous multiple primary lung cancer (SMPLC) and/or metastatic cancer. She was finally diagnosed as tuberous sclerosis complex (TSC), an autosomal-dominant disorder characterized by the fort-nation of hanaartomatous lesions in the skin, eyes, kidney, and central nervous system. Tuberous sclerosis complex 1 (TSC1) gene mutation (c.1030-1G〉A) was found in her and her family members. This is a very rare report in China.展开更多
