To investigate the cellular immunity abnormalities of patients with rheumatoid arthritis(RA), peripheral blood lymphocytes subpopulations, interleukin 2 (IL-2) production and natural killer (NK) cell activity were determined in 9 patients with RA. The results showed that there were a remarkable decrease in NK cell activity and poor response to IL-2 stimlulation. IL-2 production and.the expression of membrane-bound IL-2 receptor were increased in RA patients. The percentage of T4 positive cells and the ratio of T4/T8 were also increased in patients with RA. The results indicate that there are severe cellular immunity abnormalities in patients with RA.

The intestinal flora in patients with leukemia is significantly different from healthy people. Some studies have found that intestinal flora can participate in leukemia progression by regulating the body's immune system and hematopoietic system and affecting the metabolic function, but the underlying molecular mechanism is not clear. Maintaining the intestinal microecological balance and exploring intestinal microbes that can be used as therapeutic targets have a profound significance for prolonging the survival of leukemia patients.

Objective To evaluate the short-term efficacy and safety of sevelamer hydrochloride in treating maintenance hemodialysis (MHD) patients with hyperphosphemia.Methods A multicenter,open-labeled,self-control study was performed.Phosphate binders were discontinued during a two-week washout period.Patients with more than 1.78 mmol/L serum phosphorus after two-week washout period were eligible for the trial.The dose was adjusted every two weeks as necessary to achieve serum phosphorus control. Sevelamer hydrochloride was administered to 138 MHD patients for 10 weeks and a second two-week washout period followed.Results A total of 111 from 138 patients fulfilled the whole 14-week study. Mean serum phosphorus and calcium-phosphate products starte to decline after two-week sevelamer hydrochloride treatment. By the end of 10-week sevelamer hydrochloride treatment, mean serum level of phosphorus [(1.85±0.50) vs (2.57±0.54) mmol/L,P＜0.01],calcium-phosphate product [(4.16± 1.72) vs (5.79 ± 1.50) mmol2/L2,P＜0.01 ] and low density lipoprotein [(1.64±0.76) vs (2.31 ±0.87) mmol/L,P＜0.01] were significantly decreased,while the adjusted serum level of calcium and serum intact parathyroid hormone kept steady.Both serum phosphorus and calcium-phosphrus product increased after the second washout period, but the levels were still lower as compared to pre-treatment [(2.26±0.71) vs (2.57±0.54) mmol/L; (5.12±1.63) vs (5.79±1.50) mmol2/L2,P＜0.01].Of the 138 patients involved,214 episodes in 106 patients and 121 episodes in 89 patients were reported as adverse events and adverse drug reaction respectively. Gastrointestinal symptoms,of which most were mild or moderate,happened to 68.1％ (94/138) patients. Conclusions Sevelamer hydrochloride can control serum phosphorus and reduce the levels of calcium-phosphorus product and cholesterol.Slight gastrointestinal symptoms like constipation are common during the treatment.

Objective:To conduct a scoping review of the current research status, influencing factors, and assessment tools regarding social isolation in lung cancer survivors and provide research ideas for clinical medical and nursing staff to develop interventional measures.Methods:Based on the framework of a scoping review, systematic searches were conducted in databases including CNKI, Wanfang, VIP, CBM, Embase, PubMed, Web of Science, CINAHL, and Cochrane Library for studies on social isolation in lung cancer survivors, up to March 18, 2023.Results:Eighteen articles were included, with research distributed across three continents (Asia, North America, Europe) and in seven countries, including China, the USA, and Spain. Frequently used research tools included the University of California Los Angeles Loneliness Scale and the Cancer Loneliness Scale. Rates and severity of social isolation varied across different studies. Factors influencing social isolation in lung cancer survivors included demographic factors, disease-related factors, symptom factors, and psychosocial factors.Conclusions:Social isolation in lung cancer survivors can affect their quality of life to a certain extent. Although there are various tools for assessing social isolation in lung cancer survivors, there is a general lack of specific assessment tools. This suggests that medical and nursing personnel should consider developing and applying more specific research tools when developing related assessment tools in the future and develop personalized intervention measures based on influencing factors to help patients alleviate social isolation.
