Objective To analyze the influencing factors of sarcopenia in patients with advanced lung cancer undergoing anti-tumor therapy,and to explore the adverse effects of sarcopenia on patients with ad-vanced lung cancer undergoing anti-tumor therapy.Methods Patients with advanced lung cancer who received anti-tumor therapy in the Department of Oncology of a tertiary hospital in Chengdu from January to December 2021 were continuously included.The incidence situation of sarcopenia in patients with advanced lung cancer undergoing anti-tumor therapy was evaluated by using the 12th thoracic spine (T12) skeletal muscle index (SMI) standard.According to the diagnostic criteria of sarcopenia,the patients were divided into the sarcope-nia group and the non-sarcopenia group.Multivariate logistic regression was used to analyze the influencing factors of sarcopenia in patients with advanced lung cancer undergoing anti-tumor therapy.Results A total of 285 patients were included in this study,of which 123 cases (43.15％) were diagnosed as sarcopenia.Multiva-riate analysis showed that gender (P<0.001),pathological stage (P=0.012),creatinine (P=0.031) and BMI (P<0.001) were the influencing factors of sarcopenia in patients with advanced lung cancer undergoing anti-tumor therapy.The quality of life score of patients in the sarcopenia group was significantly lower than that in the non-sarcopenia group (P=0.035).Conclusion The incidence of sarcopenia in patients with ad-vanced lung cancer undergoing anti-tumor therapy is high,which is related to many factors and affects the quality of life.

OBJECTIVE: To explore the mediating effect of college counselors' empathy between perceived demand and behavior of helping others. METHODS: Three hundred and eleven college counselors were selected as study subjects by a convenient sampling method. The Perceived Needs Ability Questionnaire,Interpersonal Reactivity Index-C Questionnaire and Helping Behavior Questionnaire were used to assess the perceived needs,empathy ability and helping behavior of college counselors. RESULTS: The score of the empathy ability of college counselors was( 3. 4 ± 0. 4),the median scores of perceived demand ability and helping behavior were 3. 1 and 3. 3 respectively. The perceived demand ability of college counselors was positively correlated with both empathy ability and helping behavior [Spearman rank correlation coefficient( rS) = 0. 25,0. 27,P < 0. 01) ],and empathy ability was positively correlated with helping behavior( rS) = 0. 30,P <0. 01). Empathy ability has partial intermediary effect between perceived demand ability and helping behavior under the circumstances of medium-level dilemma and high-level dilemma,with the ratio of mediating effect to total effect accounting for 14. 6% and 13. 2% respectively. CONCLUSION: The perceive demand ability can directly or indirectly promote the behavior of helping others. Empathy ability plays partial mediating effects between perceived demand ability and helping behavior.

OBJECTIVETo investigate the cytogenetic differences between children and adults with acute lymphoblastic leukemia (ALL) using eight-probe fluorescence in situ hybridization and karyotype analysis.

METHODSEight-probe (MYC, P16, E2A, TEL/AML1, BCR/ABL , MLL , IGH, and hyperdiploidy) fluorescence in situ hybridization and karyotype analysis were performed for 86 adults and 39 children with acute lymphoblastic leukemia.

RESULTSEight-probe fluorescence in situ hybridization showed significant differences in the positivity rate of TEL/AML1, BCR/ABL, and hyperdiploidy between adult patients and children with ALL. By karyotype analysis, the positivity rate of t(9;22) and hyperdiploidy differed significantly between the children and adult patients (P<0.05).

CONCLUSIONAdults and children with ALL have different expression profiles of the fusion genes. Eight-probe fluorescence in situ hybridization is time-saving, accurate and efficient in detecting common genetic abnormalities in ALL patients, and can be well complementary to karyotype analysis in clinical diagnosis of ALL.

AimTo study the effects of glipizide and met formin on the serum IGF-1,IGF-2 in patients with type Ⅱ diabetes mellitus; Methods The effect of glipizide(n ＝ 40) and metformin(n ＝ 25) on serum IGF-1, IGF-2 in patients with type Ⅱ diabetes mellitus were compared with self- controlled study. Results In metformin-treated patients ,there were not significantly changes in fasting IGF-1 and IGF-2 concentrations, In glipizide-treated patients, there were markedly increased IGF-1 concentrations(181.8+ 104.5) vs (209.0+ 88.2) ng· ml-1(P＜0.05) while serum IGF-2 was not change. There was a significant reduction of blood glucose in two groups at the end of treatment(both P＜0.01), but C-peptide level was markedly increased(P＜0.05) only in glipizide-treatedpatients.Conclusion The changes of IGF-1 is markedly different between metformin-treated and glipizide-treated patients with type Ⅱ diabetes mellitus.
