Objective To understand the present situation of happiness of the elderly living in nursing homes and discuss the related factors.Methods Using the method of questionnaire,the happiness of the elderly over sixty years old and its influencing factors in eleven nursing homes in Changchun were discussed.Results Among many influencing factors,health status,the reasons for living,marital status and self-care status affected the happiness of the elderly in nursing homes.Above all,the health status had the most significant effect on happiness.Conclusions Improvement of the health level of the elderly in nursing homes can improve the happiness of them.

Objective:To introduce a surgical technique of implant-based immediate breast reconstruction using the "latent orifice" procedure after skin-sparing mastectomy and to investigate the clinical value of this procedure.Methods:Clinical data of 72 patients who underwent immediate breast reconstruction using the "latent orifice" procedure (we placed the silicone prosthesis in a "latent orifice" consisting of fascia and underlying muscles) from Jan. 2016 to Dec. 2019 were collected. Characteristics of surgical technique and the effect of the reconstruction surgery were analyzed.Results:70 patients underwent nipple-areola complex sparing mastectomy (NSM) . Two patients’ nipples were resected due to intraoperative frozen pathology suggesting carcinoma existing in the nipples. The nipple epidermal necrosis occurred in 3 patients. No seroma, incision infection or capsular contracture occurred. According to the evaluation scale, the overall aesthetic score was 9.39 points. The average score of each subscale was: 9.57 points for breast volume, 9.43 for breast contour, 9.84 for placement of implant, 9.38 for scars, 9.27 for lower pole projection and 9.21 for inframammary fold definition. BREAST-Q questionnaires were filled by patients. Scores of psychosocial well-being ranged from 62 to 93 points, with the median score of 77 points. Satisfaction with breasts scores ranged from 58 to 100 points, with the median score of 71 points.Conclusion:The "latent orifice" procedure is a simple, safe, practicable, aesthetic and satisfying type of immediate implant-based breast reconstruction, which is worth practicing and promoting.

Although immunotherapy has made a breakthrough in the treatment of cancer,the emergence of drug resistance has limited be-nefits in most patients,and reversing immunotherapy resistance remains a hotly debated and unresolved issue.The tumor microenviron-ment(TME)comprises a large number of T lymphocytes.During the biological processes of proliferation,activation,and the effect of tumor-infiltrating lymphocytes(TILs),TILs face severe local metabolic stress,resulting in metabolic reprogramming to meet the markedly increased energy demand and biosynthesis requirements.This process of adaptive changes in the metabolic pattern is closely related to the pheno-type and function of TILs,affecting immunotherapy efficacy and mediating immunotherapy resistance.In recent years,with the study of TIL metabolism and the search for specific metabolic regulatory points,targeting the TIL metabolic pathway could restore the tumor-killing func-tion and reverse immunotherapy resistance.This review explores the relationship between the metabolic reprogramming of TILs and im-mune resistance,and provides a new strategy for reversing immune resistance.

To observe the protective effect of alpha-mangostin (α-MG) on focal segmental glomurular sclerosis (FSGS) induced by adriamycin.
 Methods: Adriamycin nephropathy (AN) model was induced by adriamycin (10 mg/kg) via a tail vein. Then the mice were treated with α-MG (12.5 mg/kg) or normal salin once daily for 6 weeks. At the end of 6 weeks, the mice were sacrificed, and the kidneys and blood samples were collected. Histopathology of the kidneys were analyzed under the optical microscope. The serum levels of biochemical indicators, such as serum creatinine (SCr), blood urea nitrogen (BUN) and cholesterol were determined. The levels of superoxide anion, malondialdehyde (MDA), and glutathione (GSH), the activity of superoxide dismutase (SOD) and catalase (CAT) in kidney tissues were determined. Serum levels of IL-1β, IL-18, IL-10 and adiponectin were determined. The levels of TGF-β1, collagen I (Col I), α-SMA, silent information regulator 1 (Sirt1) and the nucleotide-binding domain (NOD)-like receptor protein 3 (NLRP3) in kidney tissues were determined using immunohistochemical staining, Western blot, and RT-PCR.
 Results: The levels of SCr, proteinuria, urine protein to creatinine ratio and serum cholesterol were attenuated in AN mice after α-MG treatment, while creatinine clearance rate and serum albumin were upregulated (P<0.05). α-MG treatment alleviated the glomerular and interstitial fibrosis, downregulated the expression of fibrosis markers, such as Col I and α-SMA (P<0.05). α-MG treatment reduced the production of superoxide anion, the levels of MDA and GSH, and increased the activity of CAT and SOD (P<0.05). α-MG treatment inhibitd the generation of pro-inflammatory cytokines, such as IL-1β and IL-18 and promoted the production of anti-inflammatory cytokines, such as the IL-10 and adiponectin (P<0.05); α-MG treatment promoted the expression of Sirt1, inhibitd the expression of NLRP3 in kidney tissues (P<0.05).
 Conclusion: α-MG could attenuates FSGS of mice induced by adriamycin ameliorate and improve renal function. α-MG exerts its anti-inflammatory and anti-oxidative effects by up-regulation the expression of Sirt1 and suppression of NLRP3.
