Objective To analyze the clinicopathological characteristics and prognosis of different subtypes of breast cancer patients with bone metastasis.Methods For this study, we recruited 300 primary breast cancer patients with bone metastasis treated at the Department of Oncology, the First Affiliated Hospital of Xi`an Jiaotong University, between September 1, 2007 and September 1, 2011.We also retrospectively analyzed their clinical and follow-up data.Results The percentage of Luminal A, Luminal B, human epidermal growth factor receptor-2 (HER-2) overexpression and triple negative subtypes in all the bone metastatic breast cancer patients was 59.0％, 16.0％, 13.7％ and 11.3％, respectively.Age, tumor size and histologic grade significantly differed among the four subtypes (P<0.05).However, there were no significant differences in menopausal status, lymph node metastasis, histological type or lymphovascular invasion among different subtypes (P>0.05).The median survival time of Luminal A breast cancer patients with bone metastasis was 28.6 months, longer than Luminal B (26.9 months), HER-2 overexpression (20.9 months) and triple negative breast cancer patients (12.0 months) with bone metastasis.The overall survival significantly differed among the patients with four subtypes of breast cancer.Conclusion Different subtypes of breast cancer patients with bone metastasis have different clinical characteristics and prognosis.Luminal A breast cancer patients with bone metastasis have better prognosis whereas triple negative subtype has poorer prognosis.

OBJECTIVE: To evaluate the modified rhytidectomy incision in superficial parotidectomy. METHOD: Thirty-five patients with superficial parotid tumor were included in this study. A modified rhytidectomy incision often used in facial plastic surgery was used for superficial parotidectomy and subtotal superficial parotidectomy with preservation of facial nerve and great auricular nerve. The follow-up study included the exposed region, the cosmetic effect of this approach and the rate of complication. RESULT: All patients healed without salivary fistula, and were satisfied with this modified approach. Temporary paralysis of the marginal mandibular branch of facial nerve were found in five patients, and six patients felt insensible around earlobe after operation. They all recovered in 1 to 3 months after surgery, no recurrence was happened during follow-up in 36 to 60 months (median follow-up period was 48 months). CONCLUSION The modified rhytidectomy incision provided good exposure, had less complication and better cosmetic outcome.

Objective: To investigate the factors influencing the development of gastric cancer in Chinese populations, so as provide insights into creating a model for predicting gastric cancer incidence among Chinese populations. Methods: The case-control and cohort studies pertaining to factors affecting the development of gastric cancer were retrieved in electronic Chinese and English databases, including CNKI, Wanfang Data, VIP, PubMed, Web of Science and Embase from their inception until September 30, 2021. A meta-analysis was performed using R package version 4.1.0. Sensitivity analysis was performed using the “leave-one-out” evaluation procedure, and the publication bias was evaluated using the Egger regression test and the trim-and-fill procedure. Results: A total of 5 301 publications were screened and 116 eligible studies were included in the final analysis, including 103 case-control studies and 13 cohort studies, which covered approximately 3.23 million study subjects. A total of 45 factors affecting the development of gastric cancer were collected, and there were less than 4 publications reporting 7 factors, which were only qualitatively described. There were 38 factors included in the final meta-analysis. A total of 21 factors were identified as risk factors of gastric cancer, including a history of gastrointestinal diseases (pooled OR=4.85, 95%CI: 3.74-6.29), H. pylori infection (pooled OR=3.18, 95%CI: 2.35-4.32), binge eating and drinking (pooled OR=2.88, 95%CI: 2.09-3.97) and a family history of tumors (pooled OR=2.78, 95%CI: 2.17-3.56), and 10 factors as protective factors, including vegetable intake (pooled OR=0.48, 95%CI: 0.38-0.61), tea consumption (pooled OR=0.55, 95%CI: 0.47-0.64), administration of aspirin (pooled OR=0.53, 95%CI: 0.31-0.92) and administration of statins (pooled OR=0.59, 95%CI: 0.44-0.80). Sensitivity analyses of eating moldy food frequently, white meat intake, favoring spicy food and administration of sulfonylureas were not robust. Following correction with the trim-and-fill procedure, there was still a publication bias pertaining to high income, diabetes, administration of stains, alcohol consumption, tea consumption and white meat intake. Conclusions The development of gastric cancer is associated with a medical history of gastrointestinal disease, H. pylori infection, family history of tumors and poor dietary habits. Risk and protective factors of gastric cancer are recommended to be included in models used to predict gastric cancer incidence among Chinese populations.

OBJECTIVE: To summarize the clinical repairment experience of postoperative skin defects in head and neck cutaneous tumor. METHOD: From July 2002 to September 2006, 24 patients with head and neck cutaneous tumor were treated in our department. Every specimen and resection margin of all cases were monitored by intraoperative frozen section. Extents of operative skin defects were from 1.0 cm x 1.5 cm to 3.0 cm x 3.5 cm, all of which were repaired by rhomboid flap. RESULT: All the cases were primarily repaired, and followed up 6 month to 3 years. The repaired skins had the normal colour, without obviously scars or secondary deformations. CONCLUSION The rhomboid flap is reasonably designed, conveniently procured and manipulated. It is a better method to immediately repair the head and neck skin defects after radical excision of tumor.

OBJECTIVE: To evaluate the role of selective neck dissection in the treatment of recurrent branchial anomalies. METHOD: The clinical data of 18 patients with recurrent branchial anomalies were retrospectively analyzed. In accordance with the embryologic and anatomic features of branchial anomalies, different types of selective neck dissection were applied. With dissection and protection of important vessels, nerves and other structures, enbloc resection principles were applied to extirpate branchial lesions, scarrings and inflammatory granuloma during the operation. RESULT: Of all 18 patients, 16 cases were healed with primary healing, 2 cases with local incision infection were healed after dressing changes. A temporary facial nerve paralysis occurred in 1 case with recurrent first branchial cleft fistula postoperatively, and completely recovered 2 months after operation. A postoperative temporary vocal cord paralysis occurred in 1 case with recurrent fourth branchial cleft fistula, and totally recuperated 1 month after operation. No recurrences were found in all 18 cases with a follow-up period of 12-78 months (average 35 months). CONCLUSION Selective neck dissection is a safe and effective surgical procedure for the radical treatment of recurrent branchial anomalies.

Purpose: Numerous studies have shown that the frequency of myeloid-derived suppressor cells (MDSCs) is associated with tumor progression, metastasis, and recurrence. Chemokine (C-C motif) ligand 3 (CCL3) may be secreted by tumor cells and attract MDSCs into the tumor microenvironment. In the present study, we aimed to explore the molecular mechanisms whereby CCL3 is involved in the interaction of breast cancer cells and MDSCs. Methods: The expression of CCL3 and its receptors was investigated using real-time polymerase chain reaction, western blotting, and enzyme-linked immunosorbent assay. The cell counting Kit-8, wound healing, and transwell assays were performed to study cell growth, migration, and invasion. Cell cycling, apoptosis, and the frequency of MDSCs were investigated through flow cytometry. Transwell assays were used for co-culture and chemotaxis detection. Markers of the epithelial-mesenchymal transition (EMT) were determined with western blotting. The role of CCL3 in vivo was studied via tumor xenograft experiments. Results: CCL3 promoted cell proliferation, migration, invasion, and cycling, and inhibited apoptosis of breast cancer cells in vitro. Blocking CCL3 in vivo inhibited tumor growth and metastases. The frequency of MDSCs in patients with breast cancer was higher than that in healthy donors. Additionally, MDSCs might be recruited by CCL3. Co-culture with MDSCs activated the phosphoinositide 3-kinase-protein kinase B-mammalian target of rapamycin (PI3K-Akt-mTOR) pathway and promoted the EMT in breast cancer cells, and their proliferation, migration, and invasion significantly increased. These changes were not observed when breast cancer cells with CCL3 knockdown were co-cultured with MDSCs. Conclusion CCL3 promoted the growth of breast cancer cells, and MDSCs recruited by CCL3 interacted with these cells and then activated the PI3K-Akt-mTOR pathway, which led to EMT and promoted the migration and invasion of the cells.

To evaluate the efficacy and safety of neoadjuvant chemotherapy combined with bevacizumab versus neoadjuvant chemotherapy alone for Her2-negative breast cancer.We searched PubMed, the Cochrane Library, Web of Science, CNKI, Wanfang Database and the abstracts of major international conferences in recent 5 years to identify prospective randomized controlled clinical trials that met the inclusion and exclusion criteria. Study selection and analyses were undertaken according to the Cochrane Handbook. Meta-analysis was performed using RevMan 5.3 software.Six trials were identified with 4440 eligible patients. The results of this meta-analysis showed that the rate of pathological complete response (pCR) was higher in Her-2 negative breast cancer patients receiving bevacizumab combined with neoadjuvant chemotherapy than that in patients with neoadjuvant chemotherapy alone (24.7% vs 20.1%,=1.23, 95%:1.10-1.37,<0.01). In addition, the pCR rate rose up when bevacizumab was added to neoadjuvant chemotherapy both in hormone receptor-positive patients (13.1% vs 10.2%,=1.28, 95%:1.04-1.58,<0.05) and in hormone receptor-negative patients (46.3% vs 37.1%,=1.25, 95%:1.12-1.39,<0.01). Statistical differences were observed in the rate of relevant adverse events such as hypertention (3.2% vs 0.6%,=5.292, 95%:2.933-9.549,<0.01) and mucositis (10.5% vs 2.0%,=5.340, 95%:3.743-7.617,<0.01) between the combination group and the chemotherapy alone group. Differences in other toxicities such as febrile neutropenia, infection, surgical complications, neutropenia and hand-foot syndrome were also found to be statistically significant between the combination group and the chemotherapy alone group (all<0.05), while such difference was not found in the occurrence of peripheral neuropathy (>0.05).The addition of bevacizumab to neoadjuvant chemotherapy in Her2-negative breast cancer can significantly improve pathological complete response, but may bring more grade 3 and 4 toxicities.More neoadjuvant trials need to be done to define subgroups of Her2-negative breast cancer that would have clinically significant long-term benefit from bevacizumab treatment.

Red blood cell (RBC) transfusion is a clinically effective therapy in anemia, for example in patients with malignancies (Shander et al., 2020), bleeding (Odutayo et al., 2017), and preoperative anemia (Padmanabhan et al., 2019). The past few decades have witnessed a shortage of blood for transfusion due to limited health insurance coverage for blood use and the rapid expansion of hospitals (Chen et al., 2011; Shi et al., 2014). Blood donation levels may easily be affected by general changes in the environment, policy, major events such as disasters, and public sentiment (Hu et al., 2019). Meanwhile, the transfusion of allogeneic RBC is a double-edged sword, increasing the possibility of infectious and immunological complications, and also leading to higher morbidity and mortality after transfusion (Frank et al., 2012). Considering that the continual shortfall has been increasingly prominent, identifying the factors associated with RBC transfusion could help blood transfusion departments to improve their supply of blood products as well as their inventory management (O'Donnell et al., 2018).
