Pancreatic cancer (PC) is known for its high malignancy and poor prognosis.Furthermore,PC patients have little chance to receive an operation,and chemotherapy is not always an ideal alternative.More effective treatment is necessary because over the last two decades,the morbidity and the mortality of PC has risen continuously.Some new PC treatments involve HER2,a transmembrane protein that has oncological significance.The amplification of its gene or over expression of itself can cause malignant proliferation,suppression of apoptosis,and angiogenesis in PC.Its potential can be seen with HER2 targeted medicines including the clinically used Trastuzumab,but also with bispecific antibody,tyrosine kinase inhibitors,and more.This article will review the application of these new developments.

Objective: To study the relationship between C-reactive protein (CRP) gene polymorphisms and the risk of chronic peri-odontitis and severe chronic periodontitis (CP) with type2 diabetes to confirm the effect of genetic factor in chronic periodontitis and chronic periodontitis with type2 diabetes. Methods; DNA was extracted by Chelex-100 from buccal swabs of patients who suffered from chronic periodontitis or chronic periodontitis with type2 diabetes and patients with healthy periodontium. PCR-RFLP was used to test the CRP genotype distribution. The correlationship between the incidence of chronic periodontitis and chronic periodontitis with type2 diabetes and CRP gene polymorphism was analyzed statistically. Results; There was no statistical difference in the distribution of CPR +1059 genotype and allele frequency between experiment group and control group (X~2 = 0. 223, P=0.994). The genotype and allele frequency distribution were in line with Hardy-Weinberg equilibrium. Conclusion; There is no correlation between CRP + 1059G/C single nucleotide polymorphisms and the susceptibility of chronic periodontitis as well as chronic periodontitis with type2 diabetes.

Objective To analyse the factors that have effects on patients' procalcitonin (PCT)level after gastic surgery and to evaluate PCT as a parameter for detection of infectious complications.Methods A total of 153 patients undergoing gastric surgery were included in the study between Jul 2011 and Jan 2013.Temperature and routine blood samples for determining PCT level,neutrophil ratio,white blood cell count were obtained on postoperative days (POD) 1,3,7.Predictive values for each of the markers were examined.Results Postoperative complication,preoperative infection and surgery type affected the PCT level of patients on POD 1.Meanwhile,the independent factor that had influence on PCT level on POD 3 and 7 was postoperative complication.After excluding those patients with preoperative infection,patients with infectious complication exhibited significantly higher PCT levels (t =2.92,P ＜0.01,t =5.34,P ＜0.01,t =4.03,P ＜0.05) on POD 1,3,7 respectively),neutrophil ratio (on POD 3 and 7) and WBC count (on POD 3) than did those without complication.According to receiver operating characteristic analysis,PCT showed the highest AUC on POD 1,7 (AUC =0.89 and 0.87 respectively).In the patients without complication,the mean PCT value was (0.47 ± 0.97),(0.36 ± 0.50),(0.23 ± 0.24) ng/ml on POD 1,3,7 respectively.The PCT level declined 55％ from POD 1 to POD 3 and from POD 3 to POD 7.Conclusions The serum PCT level of patients without any complication showed a decreasing trend while PCT level of those with infectious complications increased significantly.Continuous monitoring PCT level could serve as a diagnostic tool for the early identification of infectious complication after gastric surgery.

Objective To analyze the difference among the 3 guidehnes used to make surgical decision for branch duct intraductal papillary mucinous neoplasm (BD-IPMN),then the guidelines were combined with neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) respectively for further analysis.Methods Clinical data of 51 appropriate BD-IPMN patients who underwent surgical resection from January 2008 to December 2015 was retrospectively analyzed.Results The significant difference was exist in the consensus for followup criterion (P ＜ 0.05).The preoperative NLR and PLR were helpful for the differential diagnosis between malignant and benign BD-IPMN,because the receiver operating characteristic curve (ROC) of NLR and PLR for prediction were 0.686 and 0.692,and the best boundary values were 2.64,92.56 respectively.The consensus combined with PLR could improve the specificity and positive predictive value (PPV),besides,the specificity and PPV could achieve 70.3％,54.2％ respectively while the sensitivity (92.9％) still remained at an ideal level after international consensus guideline combined with PLR.Conclusions NLR ≥ 2.64 and PLR ≥ 92.56 were predictive markers for the presence of BD-IPMN associated invasive tumor.The addition of PLR as a criterion to the international consensus guideline improved the accuracy of international consensus guidelines in estimating invasive BD-IPMN.

The classification and treatment patterns of adenocarcinoma of esophagogastric junction (AEG)do not comply with the"gold standard"for its unique anatomical location and biological characteristics. With an increasing incidence rate of AEG in recent years, the importance of AEG in public health has caught much attention. Surgery is considered as the first choice for the treatment of AEG, but surgical treatments for different types of AEG is still controversial. Many clinical trials have proved the adjuvant therapy and neoadjuvant therapy are beneficial to the improvement of surgical resection and survival rate. Molecular targeted drugs might bring light for the treatment of advanced AEG. Individual therapy of AEG has become increasingly important with the development of science and technology and the results of large clinical researches published. This article reviews the latest progress of surgery-prioritized multimodality therapy for AEG.

Objective To investigate the cytidine triphosphate synthetase 1 (CTPS1) expression in pancreatic cancer cell lines and its impaction on prognosis.Methods The GEO profiles database was searched to collect clinical data of 39 patients of pancreatic ductal adenocarcinoma.Kaplan-Meier curve was used to analyze the relationship between the patients' prognosis and the expression of CTPS1.qPCR and Western blot were applied to detect the expression of CTPS1 in 4 pancreatic cancer cell lines.Results The mRNA expression of CTPS1 in Sw1990,BxPC-3,Panc1,and MIA-Capa2 was 1.00) ± 0.20,2.92±0.95,4.29±0.14,and 2.26±0.33 (t=-16.19,-11.45,-8.09,-13.12,P＜0.05) when compared to the normal pancreatic ductal epithelial cell line HPDE of 7.70 ± 0.72.The relative protein expression of CTPS1 in pancreatic cancer cell lines Sw1990,BxPC-3,Panc1,and MIA-Capa2 was 0.40 ± 0.06,0.20±0.09,0.68±0.11,and0.48±0.06 (t=-8.97,-10.5,-4.39,-7.88,P＜0.05) when compared to HPDE of 1.09 ±0.12.The overall survival (OS) in patients with higher CTPS1 expression than adjacent tissue was 28 months (95％ CI:9.2-46.8 months),and that with lower CTPS1 expression was 13 months (95％ CI:8.2-17.8 month),(x2 =4.02,P＜0.05).Conclusions CTPS1 in the pancreatic cancer cell lines are of low expression,and the level is positively related to patients' survival time.

Basophils, which are considered as redundant relatives of mast cells and the rarest granulocytes in peripheral circulation, have been neglected by researchers in the past decades. Previous studies have revealed their vital roles in allergic diseases and parasitic infections. Intriguingly, recent studies even reported that basophils might be associated with cancer development, as activated basophils synthesize and release a variety of cytokines and chemokines in response to cancers. However, it is still subject to debate whether basophils function as tumor-protecting or tumor-promoting components; the answer may depend on the tumor biology and the microenvironment. Herein, we reviewed the role of basophils in cancers, and highlighted some potential and promising therapeutic strategies.

In 2022, the National Cancer Center (NCC) of China reported the nationwide statistics of 2016 using population-based cancer registry data from all available cancer registries in China, which was mainly about the cancer incidence and mortality. Cancer remains a major health problem currently in our country and requires long term cooperation to deal with. This article provided a key point interpretation and analysis of cancer prevalence data in China, and provided an analysis of several main risk factors for cancer, which was conducive to the development of cancer prevention and control programs in different regions.

Objective: The role of planned neoadjuvant radiotherapy or chemoradiotherapy in the non-radical resection of esophageal squamous cell carcinoma was unclear. The study aimed to evaluate their therapeutic effect and analyze the prognostic factors. Methods: We retrospectively analyzed the clinical data of locally advanced esophageal squamous cell carcinoma who received neoadjuvant radio therapy (33 patients) and concurrent chemoradiotherapy (119 patients) from January 2004 to December 2016 in our single-institution database.The survival rates were calculated by Kaplan-Meier method. The prognostic factors were analyzed by using Log rank test and Cox proportional hazards model. Results: The median follow-up was 29.8 months. One hundred and one patients survived more than 3 years. The rates of overall survival (OS) and disease-free survival (DFS) at 3 years were 63.9% and 55.6%, respectively.The rates of complete, partial and minimal pathological response of the primary tumor were 50.3%, 38.4%, 11.3%, the corresponding 3-year OS were 75.5%, 57.4%, 27.3% (P<0.001) and 3-year DFS were 72.0%, 44.7%, 17.6% (P<0.001), respectively.The postoperative lymph node metastasis rate was 27.0%. The 3-year OS and DFS of the lymph node positive group was 45.6% and 32.8%, significantly lower than 70.8% and 63.7% of the negative group (both P<0.001). The 3-year OS and DFS of pathologic stage Ⅰ, Ⅱ, ⅢA, ⅢB and Ⅵ A were 76.2%, 57.4%, 64.7%, 35.0%, 33.3% (P<0.001) and 70.1%, 49.3%, 41.2%, 22.1%, 33.3% (P<0.001), respectively.The operation-related mortality was 3.3%. Multivariate analysis showed that chest pain, postoperative respiratory failure, pathological differentiation, more than 15 lymph node dissection and ypTNM stage were the independent prognostic factors of OS (P<0.05 for all). Conclusions The planned neoadjuvant radiotherapy or chemoradiotherapy for the non-radical resection of advanced esophageal squamous cell carcinoma could result in favorable survival. The chest pain, postoperative respiratory failure, pathological differentiation, the number of lymph node resection and ypTNM stage are the independent prognostic factors of the prognosis of these patients.
