Objective To investigate the patterns for the recurrent and metastatic gastric cancer after curative resection and to indicate the strategy of treatment. Methods 162 patients who had received radical resection and presented post-operation failure during recent 9 years were analyzed. The failure patterns were confirmed by type-B ultrasonic or CT / MRI imaging. 15 of 34 patients with abdominal dropsy were diagnosed by adenocarcinoma cells in the abdominal dropsy. All superficial lymphadens and abdominal wall metastasis were diagnosed via punctuation. 31 patients with gastric remnant and (or) anastomoses recurrence were diagnosed via biopsy. Results Of 162 patients, 63 presented the recurrence or metastasis in multiple sites,including abdominal lymph node (LN) metastases in 46.9 % (76/162), peritoneum metastases in 21.0 % (34/162),gastric remnant and (or) anastomoses recurrence in 19.1% (31/162), liver metastases in 19.1% (31/162), the incidence rates of other parts were all ＜10 %. Meanwhile, out of 76 patients with abdominal lymph node metastases, 48.7 % (37/76) patients with peri-gastric LNs metastases, 31.6 % (24/76) with peri-pancreatic LNs metastases, 19.7 % (15/76) with para-aortic LNs metastases. The incidence of LN metastases was 57.7 % (56/97) in cancer arising from gastric fundus/cardia and 60.4% (29/48) in gastric body and 64.7 % (11/17) in pylorus antrum. Conclusion The regional failure sites for gastric cancer patients with radical resection were dominantly found in the gastric stump/stoma, the peritoneum and pelvic cavity implantation and abdominal cavity LN metastases, especially in the peri-gastric, peri-pancreatic and/or para-aortic LN metastases. The distant place failure sites were mainly in the liver, lung, brain, spondylus, cervical part LN and mediastinal LN metastases. Therefore, we should take chemotherapy, abdominal cavity chemotherapy and regional radiotherapy to prevent the regional district recurrences and distant metastasis after the gastric cancer patients with radical resection. Radiotherapy fields should focus on the gastric stump/stoma and the peri-gastric, peri-pancreatic and para-aortic LN regions.

Objective:To identify the healing effect of electrospun silk fibroin-BMP-2 as a biologic pulp capping agent to inflammatory pulp in rat caused by lipopolysaccharide ( LPS) .Methods:A total of 30 healthy adult male Wistar rats were randomly divided into five groups:(1) normal control group without operation;(2) blank control group without capping agents;(3) calcium hydroxide capping group;(4) electrospun silk fibroin capping group;(5) electrospun silk fibroin-BMP-2 capping group .Bilateral up-per first molars of each rat in group 2-5 were drilled to expose the pulp to LPS which was used to estab-lish a model of inflammatory pulp .The exposed pulp was capped with different capping agents or without capping agents.Then the hole was sealed.The animals were sacrificed on days 3, 7, and 14 post-opera-tion and histological analysis was carried out , including HE stain and CD 14 immunohistochemical stain . Results:On day 7 and 14 , the lowest inflammatory reaction score in HE stain among pulp capping groups was that of silk fibroin-BMP-2 group .The next were calcium hydroxide group and silk fibroin group .That of blank control group was the highest .The ranking of reparative dentine scores of those groups was just reversed.The D values of immunohistochemical stain of CD 14 were not significantly different in groups applied pulp capping agents but significantly lower than blank control group on days 3 and 7.However, the D value of silk fibroin-BMP-2 group ( 0 .145 ±0 .011 ) was significantly lower than blank control group (0.287 ±0.019), calcium hydroxide group (0.170 ±0.017) and silk fibroin group (0.175 ± 0 .018 ) on day 14 .Conclusion:Electrospun silk fibroin compounded with BMP-2 promoted wound hea-ling of exposed pulp and had better potential to stimulate formation of reparative dentine to establish a suitable environment for pulp recovery .

Objective To explore the influence of nursing intervention on the social support and compliance of parents of severe β-Mediterranean anemia children. Methods A total of 100 cases of Mediterranean anemia children’s parents were surveyed with the Social Support Rating Scale (SSRS) and self-made compliance questionnaires, the investigation was performed before the intervention,6 months, 1 year after the intervention. Results The scores of objective support, subjective support and supporting availability after the intervention were all higher than those before intervention (F=269.04, 125.12, 243.04, all P<0.01). In the pairwise comparison tests, the ranks of objective support score and subjective support score were:1 year after intervention>6 months after intervention>before intervention (P<0.01);the score of supporting availability was lower than the scores of 6 months and 1 year after intervention (P<0.01). The compliance of blood transfusion on time and taking deferoxamine on time before and after the interventions had statistical meanings (Hc=100.40,70.53, all P<0.01). In the pairwise comparison tests, the compliance score before intervention was lower than the score after intervention (P < 0.01). Conclusions Nursing intervention can improve the social support and compliance of the parents with severe Mediterranean anemia children.

Objective To investigate the effects of Rosa Laevigata Michx Flavoid( RLMF) and Rosa laevigata Michx Polysaccharose (RLMP) on expression of TRPV5 in IgA Nephropathy (IgAN) rat renal tissue. Methods Forty Sprague-Dawley rats were randomly assigned to four groups.The rat model of IgA nephropathy was induced by intragastric administration of bovine serumalbumin and injections of LPS and CC14.Eight weeks later,the rats with IgAN were treated with RLMF or RLMP (4 weeks), or normal saline.Rats was sacrificed at thirteenth weeks, and RNA was extracted from the kidney.Expression of TRPV5 in tubulointerstitial tissues were analyzed by fluorescent quantitative RT-PCR. Results After RFLP intervention,the expression levels of TRPV5 were markedly increased (P<0.01) than model control group,while decreased (P<0.05) than normal control group but had no significance with model control group after RFLF intervention. Conclusion TRPV5 expression is decreased in IgAN,and RLMP can adjust TRPV5 expression and improve renal function of IgAN.

Objective: To investigate the current status of fear of cancer recurrence in bladder cancer patients, and to explore the correlation between fear of recurrence and quality of life. Methods: A total of 96 bladder cancer patients were recruited by convenience sampling method from April 2017 to July 2017. They were investigated through general information questionnaire, Chinese version of Fear of Progression Questionnaire Short Form and Functional Assessment of Cancer Therapy-Bladder cancer form respectively. Results: The total score of fears of recurrence was 28.76±10.33, the total score of quality of life was 123.66±20.63. A total of 28 patients had a dysfunctional level of fears of recurrence (total score ≥34), the incidence was 29.2% (28/96). There were significant differences in the total scores of fears of recurrence at different ages, fears of recurrence were not related to another sociodemographic factors (gender, educational attainment and income) or disease, treatment related factors. The total scores of fears of recurrence and the total score of quality of life showed a high degree of negative correlation (r=-0.726, P < 0.01), the quality of life in physical, social and family, emotional, functional well being were negatively correlated with fears of recurrence (r=-0.841--0.592, P < 0.01). Conclusions Bladder cancer patients have a higher incidence of fears of recurrence and had an impact on quality of life from the physical, psychological and social domains, nurses should perceive the fears of recurrence of patients as soon as possible and give corresponding intervention measures to improve the quality of life of bladder cancer patients.
