Methods The cell growth curve was drawn by MTT;the apoptotic cells were detected by Annexin, V and PI double staining; the expression of Caspase-3 was detected by Westernblot; the activity of telomerase was detected by TRAP-PCR silver staining. Results Curcumin could significantly inhibit the proliferation of SKBR3 cells in a time and concentration dependent, has a certain effect on reducing the telomerase activity of SKBR3 cells can enhance the expression of Caspase-3 induced apoptosis. Conclusion Curcumin can effectively inhibit the proliferation of SKBR3 cells, increase the synthesis of Caspase-3 protein, inhibit the activity of telomerase and mediate the apoptosis of SKBR3 cells.

Objective To detect the ratio of CD19+-CD25+ and CD19+-CD25-B lymphocytes and content of IgA,IgG,IgM and complement C3 in patients with acute cerebral infarction and study their clinical significance. Methods Disease were diagnosed according to the history and cranlal computer tomography or magnetic resonance imagine.Venous blood of 69 cases with acute cerebral infarction and 115 cases with cerebral hemorrhage, 41 cases in normal control group was extrdcted. The ratio of CDl9+-CD25+and CD19+-CD25-B lymphocytes was determined by flow cytometry and content of IgA,IgG,IgM and C3 was measured with scattering turbidimetry.Changes in humoral immunological function were compared among patients with different courses of disease, imaging scores and neurological function scores. Results Differences in CD19+-CD25+and CD19+-CD25-B lymphocytes, IgA, IgG,IgM and C3 were not significant at the acute stage between cerebral infarction and cerebral hemorrhage (P＞0.05,for all).The ratio of CD19+-CD25+B lymphocytes and content of IgG and C3 at the acute stage of cerebral infarction were all higher than that at the recovery stage and in the control group (P＜0.05, for all). There was no statistical signmcance in humoral immunological indices between that at the recovery stage of cerebral infarction and in the control group (P＞0.05, for all). The ratio of CD19+-CD25+ and CD19+-CD25-B lymphocytes was significantly different among patients with different imaging scores (P＜0.05,for all).Neurological function scores at the acute stage of cerebrdl inflarction were not correlated with humoral immunological indices(P＞0.05,for all). Conclusions Same changes occur to humoral immunological function in patients with cerebral infarction and cerebral hemomlage, which might be related with stress,and location and scope of lesions.The larger the lesion of cerebral infarction is,the more obvious changes of humoral immunological function become; with the disappearing of stress,humoral immunological function gradually recovers.

OBJECTIVETo investigate the effects of fluoride on lipid peroxidation, DNA damage and apoptosis in human embryo hepatocyte L-02 cells.

METHODSLipid peroxide (LPO) level, reduced glutathione (GSH) content, DNA damage, apoptosis, and cell cycle analysis were measured after in vitro cultured L-02 cells were exposed to sodium fluoride at different doses (40 microg/mL, 80 microg/mL, and 160 microg/mL) for 24 hours.

RESULTSFluoride caused an increase of LPO levels and a decrease of GSH content in L-02 cells. There appeared to be an obvious dose-effect relationship between the fluoride concentration and the observed changes. Fluoride also caused DNA damage and apoptosis and increased the cell number in S phase of cell cycle in the cells tested. There was a statistically significant difference in DNA damage and apoptosis when comparing the high dose of fluoride treated cells with the low dose of fluoride treated cells.

CONCLUSIONFluoride can cause lipid peroxidation, DNA damage, and apoptosis in the L-02 cell experimental model and there is a significant positive correlation between fluoride concentration and these pathological changes.

Objective:To investigate the types of non-tumor diseases in patients with cancer, and to explore the effects of those dis-eases on the diagnosis and treatment of cancer patients. Methods:We collected the medical records of cancer patients from January 2013 to December 2017 in Peking University Cancer Hospital, and screened for non-tumor diseases. The clinical records of the patients in this group were analyzed retrospectively, and the effects of those diseases on the diagnosis and treatment of tumors were dis-cussed. Results:Of the 1,323 cases of inter-hospital consultation, 1,153 cases of non-tumor disease (87.2％) were selected. There were 773 men (67.0％) and 380 women (33.0％) included. The median age was 62 (14-90) years. The primary tumor types included lung can-cer, gastric cancer, lymphoma, colorectal cancer, esophageal cancer, breast cancer, malignant melanoma, liver cancer, cholangiocarci-noma/gallbladder cancer, pancreatic cancer, and other tumors. Non-neoplastic diseases included cardiovascular disease in 356 cases (30.9％), respiratory system disease (17.0％) in 196 cases, digestive system disease in 107 cases (9.3％), skin and venereal diseases in 81 cases (7.0％), nervous system lesions (6.4％) in 74 cases, urinary system disease in 72 cases (6.2％), blood disease in 70 cases (6.1％), en-docrine and metabolic diseases in 47 cases (4.1％), autoimmune disease in 23 cases (2.0％), and other diseases (11.0％) in 127 cases. Impact on tumor diagnosis and treatment was as follows:direct, 771 cases (66.9％);no influence, 313 cases (27.1％);and uncertain, 69 cases (6.0％). Conclusions:Cardiovascular disease is a major non-tumor disease associated with cancer. Non-neoplastic diseases are important factors affecting the diagnosis and treatment plans of cancer.

Objective:To study the clinical characteristics of neonatal gastric perforation (NGP) and risk factors of mortality.Methods:From January, 2015 to December, 2021, clinical manifestations of neonates diagnosed with NGP in the Department of Neonatology and Neonatal Surgical Intensive Care Unit of our hospital were retrospectively analyzed. Neonates were assigned into the survival group and the death group according to their prognosis. Risk factors of mortality were analyzed using multivariate logistic regression method.Results:A total of 50 cases were enrolled, including 41 in the survival group and 9 in the death group. 38 cases were males, 34 were premature infants, 30 were low birth weight infants and 5 had history of asphyxia. The clinical manifestations included abdominal distension, tachypnea, cyanosis, poor response, fever, diminished bowel sound and redness of the abdominal wall. Abdominal X-ray indicated pneumoperitoneum. Laboratory abnormalities included leukocytosis, thrombocytopenia, elevated C-reactive protein and procalcitonin, decreased blood pH and increased lactic acid. 30 cases had perforation at the greater curvature of stomach. Perforation was larger than 3 cm in 40 cases and intestinal necrosis was identified in 14 cases. Some patients suffered from sepsis, respiratory failure, pulmonary hemorrhage, shock, coagulopathy and other related complications. The death group had significantly higher incidences of dyspnea, fever, elevated procalcitonin, blood pH<7.3, intestinal necrosis, time from onset of clinical manifestations to operation (Tm-o) >24 h and complications than the survival group ( P<0.05). Multivariate logistic regression analysis showed that pH<7.3 ( OR=9.755, 95% CI 1.363-69.800), Tm-o>24 h (OR=11.831, 95%CI 1.305-107.301), septic shock and sepsis ( OR=29.622, 95% CI 3.728-235.369) were risk factors of mortality. Conclusions:The main manifestations of NGP are abdominal distension and pneumoperitoneum. The risk factors of mortality in NGP are sepsis, blood pH<7.3 and Tm-o>24 h.

Objective:To investigate the intervention effects and influencing factors of family management intervention on parents' disease management ability, family function of children with coronary artery lesions in Kawasaki disease.Methods:This was a quasi experimental study. Conveniently, 88 parents of children with Kawasaki disease coronary artery lesions from the Children's Hospital of Chongqing Medical University from March 2020 to June 2021 were selected for the study, and they were divided into the control group and the intervention group according to the order of the first consultation with 44 cases in each group. In the control group, conventional care and health education were used, while in the intervention group, a 6-month family management intervention was implemented on the basis of the control group. Family Management Measure (FaMM), Family Assessment Device (FAD) were used to assess the parents' disease management ability, family function before and after the intervention, respectively.Results:A total of 88 study subjects completed the pre-intervention survey in this study, and a total of 79 study subjects were surveyed when they returned to the hospital for review at the end of 6 months of intervention, including 40 in the intervention group and 39 in the control group, with a missed rate of 10.23% (9/88). There was no significant difference in the score of FAD, FaMM, Kawasaki disease knowledge questionnaire before the intervention between the two groups ( P>0.05). The scores of FAD in the intervention group was (21.58 ± 4.60) points, which was lower than that in the control group (24.62 ± 5.28) points, and the difference was statistically significant ( t=2.73, P <0.05). The scores of FaMM in the intervention group was (46.83 ± 6.02) points, which was higher than that in the control group (42.72 ± 6.09) points, and the differences was statistically significant ( t=-3.01, P <0.05). The age of the child, and whether the child was an only child were the influencing factors of the difference in disease management ability, and the difference in the family function of the parents of the child, respectively (all P<0.05). Conclusions:Family management intervention can improve the disease management ability of the parents of children with coronary artery lesion, improve family function. In the future, targeted interventions can be conducted according to different ages of children, and different family members' composition in order to obtain better intervention effects.

Background and objective Lung cancer is currently the leading cause of cancer death, two thirds of patients are over the age of 65. Small cell lung cancer (SCLC) accounts for about15%-20%of all lung cancer. hTe objective of this study is to evaluate the survival of patients older than 65 with SCLC and analyze the independent prognostic factors in this group of patients. Methods A retrospective study has enrolled160 cases of lung cancer aged over 65. hTe prognostic factors were analyzed by Kaplan-Meier and Cox multivariate proportional hazards model. Results ①hTe median follow-up time was12 (2-109) months.1-, 3-, and 5-year survival rate was 47.1%,13.0%, 9.6%respectively, and 74.4%, 25.0%,19.7%for limited-stage (LD), and 36.8%, 8.7%, 5.8%for extensive-stage (ED). Median survival time (MST) of all the patients was12 months, 24 months for LD and11months for ED, respectively.②Multivariate analysis suggested that performance status (PS) pre-treatment, the change of PS atfer treatment, stage, liver metastases and thoracic radiotherapy were the independent prognostic factors in all patients.③For LD-SCLC patients, PS pre-treatment, thoracic radiotherapy were the independent prognostic fac-tors. hTe model of thoracic radiotherapy (concurrent chemoradiation vs sequential chemoradiation, early concurrent chemo-radiation vs late concurrent chemoradiation) and prophylactic cranial irradiation (PCI) did not show signiifcant difference.④For ED-SCLC patients, sex, the change of PS atfer treatment, chemotherapy, liver metastases, thoracic radiotherapy, PCI were the independent prognostic factors. Conclusion hTe survival time is related to PS and thoracic radiotherapy in eldly patients. Besides, it is also related to sex, chemotherapy, liver metastases and PCI for ED-SCLC.

Background and objective Radiotherapy combined with chemotherapy or molecular targeted therapy remains the standard of treatment for brain metastases from non-small cell lung cancer (NSCLC). hTe aim of this study is to determine if the deferral of brain radiotherapy impacts patient outcomes.Methods Between May 2003 and December 2015, a total of 198 patients with brain metastases from NSCLC who received both brain radiotherapy and systemic therapy (chemo-therapy or targeted therapy) were identiifed. hTe rate of grade 3-4 adverse reactions related to chemotherapy and radiotherapy had no signiifcant difference between two groups. 127 patients received concurrent brain radiotherapy and systemic therapy, and 71 patients received deferred brain radiotherapy after at least two cycles of chemotherapy or targeted therapy. Disease speciifc-graded prognostic assessment was similar in early radiotherapy group and deferred radiotherapy group.Results Me-dian overall survival (OS) was longer in early radiotherapy group compared to deferred radiotherapy group (17.9 monthsvs 12.6 months;P=0.038). Progression free survival (PFS) was also improved in patients receiving early radiotherapy compared to those receiving deferred radiotherapy (4.0 monthsvs 3.0 months;P<0.01). Receiving tyrosine kinase inhibitor (TKI) therapy atfer the diagnosis of brain metastases as any line therapy improved the OS (20.0 monthsvs 10.7 months;P<0.01), whereas receiving TKI as ifrst line therapy did not (17.9 monthsvs 15.2 months;P=0.289).Conclusion Our study suggests that the use of deferred brain radiotherapy may resulted in inferior OS in patients with NSCLC who develop brain metastases. A prospec-tive multi-central randomized study is imminently needed.
