Accurate preoperative staging is imperative in the treatment of gastric cancer since diseases in different stages mandate different management strategies. Multi-disciplinary therapy is important for gastric cancer. Endoscopic treatment has become the preferred treatment for patients with early gastric cancer. However, only when multiple disciplines is involved in the decision-making process, appropriate patients can be selected and benefit from the minimally invasive treatment. In China, 90% of gastric cancers are at advanced stage at diagnosis, which are associated with worse prognosis compared to early gastric cancer. The optimal treatment depends on the multi-disciplinary therapy including surgery, chemotherapy, radiotherapy, and molecular targeted therapy.

Objective To investigate the effect of docetaxel combined capecitabine chemotherapy and psychological intervention after radical mastectomy. Methods 80 cases of radical mastectomy for breast cancer treated in our hospital from January 2015 to January 2017 were treated with docetaxel combined with capecitabine chemotherapy. According to different nursing methods, the patients were divided into 2 groups. The observation group was treated with psychological nursing, while the control group received routine nursing care. The anxiety and depression scores in two groups before and after nursing were observed and compared. Results There were no significant difference in the scores of anxiety and depression between the two groups before and after treatment. After the intervention group, patients in observation group were significantly improved, and better than the control group patients; The nursing satisfaction rate in the observation group was 97.5%,which was significantly higher than that in the control group (72.5%) (P<0.05). Conclusion After radical mastectomy of breast cancer with docetaxel combined with capecitabine chemotherapy and psychological clinical observation of dry pre found in breast cancer resection and chemotherapy as the basis, to patients with psychological intervention can improve the clinical situation of patients, promote their mental status improved, improve nursing satisfaction rate of patients, so it is worthy of reference.

Xanthine oxidase (XOD), catalyzing purine metabolism, is the key enzyme in uric acid (UA) biosynthesis, and becomes an important target for hyperuricemia treatment. The inhibition on XOD plays an important role in the treatment of hyperuricemia-related diseases, such as gout, as well as oxidative stress-induced tissue injury. Here, studies on the natural products with XOD inhibition are reviewed.

Objective:To analyze the clinical characteristics of functional esophagogastric junction outflow obstruction (EGJOO) and to improve the knowledge of functional EGJOO.Methods:From January 2015 to December 2019, at the Gastrointestinal Motility Center of The First Affiliated Hospital with Nanjing Medical University, 91 patients who underwent high resolution esophageal manometry (HREM) and met the EGJOO criteria of Chicago Classification for esophageal motility disorders, 3rd edition and excluded organic diseases by examination such as gastroscopy or upper gastrointestinal radiography were collected. The clinical manifestations, treatment methods, effect and clinical outcome of patients with functional EGJOO, the HREM parameters of patients with different clinical manifestations as well as symptoms and HREM parameters of patients with different treatments were analyzed. Least significant difference test or Tamhanes T2 test, Mann-Whitney U or Wilcoxon test, chi-square test or Fisher exact test were used for statistical analysis. Results:The most common symptom of 91 functional EGJOO patients was dysphagia (34/91, 37.4%). The lower esophageal sphincter pressure (LESP) and the intrabolus pressure during relaxation of the lower esophageal sphincter (IBP LESR) of patients with dysphagia were both higher than those of patients without dysphagia (30.95 mmHg (26.27 mmHg, 39.37 mmHg) (1 mmHg=0.133 kPa) vs. 27.35 mmHg (24.60 mmHg, 34.87 mmHg); (8.25±4.64) mmHg vs. (5.69±4.65) mmHg), and the differences were statistically significant ( Z=2.076, t=2.539; P=0.038, 0.013). Thirty patients (33.0%) had no special treatment, 52 patients (57.1%) were treated with medication, and nine patients (10.0%) underwent peroral endoscopic myotomy (POEM). The incidence of dysphagia before treatment and maximum intrabolus pressure of patients who underwent POEM were both higher than those of patients without special treatment and medication treatment (8/9 vs 43.3%, 13/30 and 25.0%, 13/52; 21.80 mmHg (15.45 mmHg, 28.95 mmHg) vs. 12.20 mmHg (10.00 mmHg, 18.10 mmHg) and 13.70 mmHg (11.07 mmHg, 17.82 mmHg)), and the differences were statistically significant (Fisher exact test, Fisher exact test; Z=2.814, 2.390; P=0.023, P<0.01, P=0.005, 0.017). The incidences of delayed esophageal emptying or esophageal dilation of patients who underwent POEM, without special treatment and with medication treatment was 6/9, 5/14 and 3/18, respectively, and the differences were statistically significant among three groups (Fisher exact test, P=0.039). Among them, the incidence of delayed esophageal emptying or esophageal dilation of patients received POEM before treatment was higher than that of patients with medication treatment (Fisher exact test, P=0.026). The symptoms of 24.2% (22/91) was spontaneously relieved, and two patients (2.2%) developed type Ⅱ achalasia during follow-up. Conclusions:The main manifestation of patients with functional EGJOO is dysphagia. Patients with significantly increased LESP and IBP LESP are more likely to have dysphagia. Patients with obvious signs of esophageal gastric junction obstruction are more inclined to choose POEM treatment. Some patients with functional EGJOO can relieve themselves, and a few patients can develop achalasia.

Background and purpose:Chemotherapy plays an important role in the treatment of breast carcinoma by inhibiting the tumor growth and inducing the apoptosis.MAPK transduction pathway is closely related to proliferation and apoptosis of varieties of tumor cells,inhibition of MAPK pathway may increase the efficiency and decrease the toxicity of chemotherapy.Our study was to investigate the effect of MEK inhibitor PD98059 in response of breast cancer cell lines to Epirubicin.Methods:Human breast cancer cell lines MCF-7 and MCF-7/ADR were used as cell models.Epirubicin(EADM),PD98059(inhibitor of MAPK Kinase-MEK),or EADM+PD98059 was added into the culture medium,the expression of MEK2 and p-ERK were measured by Western blot,the growth of the two cell lines were measured by MTT.Results:ERK activity was elevated in MCF-7 after the treatment of EADM,the cells were more sensitive to EADM if combined with PD98059,while in MCF-7/ADR,ERK activity kept unchanged after EADM treatment,and PD98059 has no effect on the sensitivity of cells to EADM.Conclusion:MAPK signal transduction may be activated in some cells treated by EADM,adding inhibitor of MAPK signal transduction could improve the sensitivity of the cells to EADM.

Objective To analyze and summarize the imaging features of hepatic epithelioid hemangioendothelioma (EHE).Methods The retrospective and descriptive study was conducted.The clinicopathological data of 9 patients with EHE who were admitted to the Cancer Hospital of Chinese Academy of Medical Sciences between June 2012 and June 2016 were collected.Patients underwent computed tomography (CT) and magnetic resonance imaging (MRI) examinations.Number,size,location,shape,density or signal and enhancement method of lesions,with or without lesions fusion and relationship between lesions and vessels were analyzed by 2 imaging doctors.Lesions in left lobe of liver,right lobe of liver and caudate lobe of liver were respectively counted.Real number was a standard as less than 5 lesions and more than or equal to 5 lesions was represented as ≥ 5.Observation indicators:(1) overall imaging features of EHE;(2) MRI findings of EHE;(3) CT findings of EHE;(4) treatment and pathological features of EHE and results of follow-up.Patients received the corresponding treatment after imaging examinations.Follow-up using outpatient imaging examinations was performed to detect tumor recurrence and stable condition of patients up to December 2016.Results (1) Overall imaging features of EHE:of 9 patients with EHE,6 received plain and enhanced scans of MRI,3 received plain and enhanced scans of CT (1 combined with MRI),1 received enhanced scan of CT.Lesions in right lobe of liver were more than that in left lobe of liver,and there were fewest lesions in caudate lobe of liver.Lesions were round or similar-round shape,with a maximum diameter of 2.5-6.1 cm and an average diameter of 3.6 cm.Four patients had total 2-5 lesions and less than 5 lesions in each lobe of liver,without lesions fusion,including 1 with halo sign and capsule retraction sign and 1 with halo sign.Of other 5 patients,2 had more than or equal to 5 lesions in each lobe of liver and 3 had more than or equal to 5 lesions in 2 lobes of liver;4 had halo sign,lollipop sign,capsule retraction sign and a tendency of lesions fusion,1 had halo sign and capsule retraction sign.The halo sign,lollipop sign,capsule retraction sign and a tendency of lesions fusion were 7/9,4/9,6/9 and 4/9 in 9 patients,respectively.(2) MRI findings of EHE:6 patients received plain and enhanced scans of MRI.① Four patients had clearhalo sign on T2 weighted imaging (T2WI),in portal vein phase and hepatobiliary phase.Three patients had slightly central hyperintensity and thick ring of slightly peripheral hyperintensity on T2WI.There were slightly central hyperintensity and thin ring of slightly peripheral hypointensity in 1 patient,and the halo sign was seen by enhanced scan.There were central hyperintensity and peripheral hypointensity in 2 patients,and the halo signs were clearly seen in hepatobiliary phase.Some patients were combined with multiple manifestations.② There were no obvious halo sign on T2WI,annular enhancement in arterial phase by enhanced scan,no obvious halo sign in portal vein phase and hepatobiliary phase in 2 patients.There were hypointensity on T1WI and isointensity-hyperintensity on DWI in 6 patients.(3) CT findings of EHE:plain scan of CT in 4 patients showed slightly hypodense shadow,without calcification.Enhanced scan of CT in 3 patients showed that obvious halo-like enhancement was seen in portal vein phase and halo rings were less obvious than that by MRI examination.(4) Treatment and pathological features of EHE and results of follow-up:of 9 patients with EHE,4 underwent surgical resection based on lesions ≤5 and surgical specimens were detected by pathological examination,5 underwent interventional treatment and pathologic examination with biopsy.Gross specimen examination showed that lesions were solid and stiff,with greyish white section plane and infiltrative margin.Tumor cells consisted of epithelioid cells under the microscopy,without atypia and with rare mitotic figures,and vacuoles were seen in cytoplasm.Immunohistochemistry showed CD31 and CD34 were positive.Nine patients were followed up for 6-54 months.During the follow-up,4 patients with surgery had no recurrence and 5 patients with interventional therapy remained stable condition.Conclusions Imaging manifestations of hepatic EHE are the more typical when lesions of EHE became more.Hepatic EHE has a tendency of lesion fusion,halo sign,capsule retraction sign and lollipop sign.Imaging manifestations on T2WI with fat suppression,in portal vein phase and hepatobiliary phase are helpful to improve the diagnosis of hepatic EHE.
