Objective To investigate the radiosensitiation effect of berberine on human nasopharyngeal carcinoma ( NPC) in hypoxia condition and explore the underlying mechanisms. Methods MTT assay, clonogenic assay and flow cytometry were performed to analyze cell proliferation, colony formation and apoptosis, respectively. Male nude mice inoculated subcutaneously with CNE-2 cells were used to examine the radiosensitization effect of berberine in vivo. The expressions of HIF-1α and VEGF were assessed by Western blot. Results Berberine efficiently inhibited the proliferation of CNE-2 cells in time-dependent and dose-dependent fashions with an IC50 of ( 14?9 ± 2?2 ) μmol/L. Clonogenic survival assay showed that berberine ( 5 μmol/L ) sensitized CNE-2 cells to ionizing radiation in hypoxia and its SERD0 was 1?27. Under hypoxic condition, berberine alone (5, 15 μmol/L) could induce apoptosis (t=5?01, 9?02,P<0?05) and it further promoted 8 Gy radiation-induced apoptosis (t =5?31, 9?91,P <0?05). Moreover, berberine significantly delayed the tumor growth in the combination group (berberine +irradiation) compared with the mice received irradiation alone or PBS (t =2?96, 14?52, P <0?05). Immunobloting assay showed that berberine inhibited the upregulation of HIF-1α and VEGF induced by hypoxia in CNE-2 cells. Conclusion Berberine confers radiosensitivity on hypoxic NPC in vitro and in vivo, which is probably associated with the downregulation of HIF-1α and VEGF expressions.

Objective:To observe the clinical effect on patients of invasive ductal carcinoma of the breast by neoadjuvant chemotherapy, and to analyze the changes of estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor-2 (HER-2) and Ki67 in neoplasm.Methods:A total of 83 patients which were treated by neoadjuvant chemotherapy in breast invasive ductal carcinoma diagnosed were selected in North China University of Science and Technology Affiliated Hopital from January 2014 to December 2020. There were 30 cases of Luminal type A, 31 cases of Luminal type B, 10 cases of HER-2 positive type and 12 cases of triple negative type. To observe the clinical effect of different molecular subtypes, detect the expression of Er, PR, HER-2 and Ki67 in pathological tissues before and after neoadjuvant chemotherapy, and conduct a retrospective case-control study. Comparison between the two groups use χ2 test, matched χ2 and accurate probability method. Results:Fifty-eight cases were clinically effective, the total effective rate was 69.8% (58/83), and 9 cases were pathological complete response (pCR), accounting for 10.8% (9/83). After neoadjuvant chemotherapy, the highest clinical efficacy was luminal type B in 26 cases, and the highest PCR was triple negative type in 3 cases. The pathological results showed that the expression of ER (6 cases of positive expression were increased, χ2=1.03, P=0.310), PR (8 cases of positive expression were increased, χ2=1.56, P=0.210) and HER-2 (2 cases of positive expression were decreased, χ2=0.10, P=0.748) was not different before and after neoadjuvant chemotherapy. The expression of Ki67 was decreased in 25 cases (30.1%) after chemotherapy compared with 59 cases (71.1%) before chemotherapy (34 cases of positive expression were decreased, χ2=27.85, P<0.001). Five cases were added among Luminal type A after chemotherapy, all of which were transformed from Luminal type B, but the kappa value was 0.919 (>0.75), the consistency rate was 91.9%. The consistency was idea before and after chemotherapy. Five cases were added after Luminal type A chemotherapy, all of which were transformed from Luminal type B, but the kappa value was 0.919 ( P>0.75), and the consistency rate was 91.9%,The consistency before and after chemotherapy was good. After chemotherapy, HER-2 expression remained unchanged in 59 cases (clinically effective in 48 cases), up-regulated in 9 cases (clinically effective in 4 cases) and down regulated in 15 cases (clinically effective in 6 cases)( χ2=12.82, P=0.002). Ki67 expression remained unchanged in 35 cases (20 cases were clinically effective), up-regulated in 7 cases (2 cases were clinically effective) and down regulated in 41 cases (36 cases were clinically effective)( χ2=14.63, P=0.001). Conclusion:The clinical effect of neoadjuvant chemotherapy in the treatment of breast invasive ductal carcinoma is ideal. The clinical effective rate of Luminal B type is the highest, and the pCR rate of triple negative type is the highest.And it can significantly reduce the expression of Ki67. The down-regulation of HER-2 and Ki67 is significant for clinical efficiency.

Objective:To summarize our experience in diagnosis and treatment of patients with pulmonary mucosa-associated lymphoid tissue-derived(MALT) lymphoma and to explore the role of surgery.Methods:We retrospectively analyzed the clinical and follow-up data of 86 patients with pulmonary MALT lymphoma in Shanghai Pulmonary Hospital from January 2000 to December 2018. 86 cases were identified with 44 males and 42 females. The mean age was(56.7±10.6) years old. 38(44.2%) cases had symptoms mainly presenting as cough and sputum at diagnosis. The chest CT scan of the patients showed pulmonary consolidation in 39 cases, nodule/mass shadow in 37 cases, usually with air bronchogram. Only 8(9.3%) cases could be diagnosed by non-surgical approach. 58 cases received complete resection, 10 of which followed chemotherapy. 8 of 17 cases who received incomplete resection accepted chemotherapy. The rest 11 cases who experienced surgical biopsy because of uncertain diagnosis were treated by chemotherapy or radio-chemotherapy or just watch-to-wait.Results:The median follow-up of 83 cases was 64 months, ranged from 24 to 219 months. The estimated 5-year and 10-year OS rates were 95.0% and 76.8%, while 5-year and 10-year PFS were 75.7% and 35.1% respectively. Patients who received complete resectionhad better PFS( P<0.001)but similar OS( P=0.395), compared with those received incomplete resection. There were no significant difference in OS and PFS between patients who received complete resection accepted chemotherapy or not( P>0.05). Conclusion:Pulmonary MALT lymphoma has an indolent nature with an excellent long-term survival. Diagnosis is difficult to be made by non-surgical approach. Surgery plays an important role of treatment of pulmonary MALT lymphoma, due to significant improvement of diagnosis rate and radical treatment of localized disease by complete resection.
