Objective: To explore the intervention effect of group counseling integrating teadrinking on depression, social avoidance and distress, coping styles and selfesteem among college students, so as to provide references for promoting the psychological health of students. Methods: From March to June 2021, a convenience sampling method was used to recruit 46 college students from a university in Nanjing for intervention project. There were 23 students in intervention group and control group, respectively. The intervention was conducted for 2.5 hours per week across a 6 week period. The intervention group received two sessions of group counseling that incorporated teadrinking experience, and the sessions involved tea knowledge explanation, observation and learning, embodied experience, emotional expression, interpersonal assistance and emotional support, cultural customs and life integration. After the intervention was completed, the control group received onetime group counseling that integrated teadrinking. The Wilcoxon difference test and Mann-Whitney U test were performed to compare the scores of each scale within and between the groups, and the χ2 test was used to compare the detection rates. Results: There were no statistically significant differences in the scores of positive coping, negative coping, selfesteem, social avoidance and distress between the intervention group and the control group (Z=-1.20, -0.33, -0.35, 1.31,P>0.05). There were statistically significant differences in positive coping styles, selfesteem, social avoidance and distress between the intervention group and the control group after the intervention(27.70±5.60，22.05±4.30；30.52±3.63，28.27±4.06；7.43±7.38，13.64±6.79) (Z=-3.31, -2.10, 3.22, P<0.05). The intervention group showed statistically significant differences in social avoidance and distress scores before and after the intervention(11.96±7.47,7.43±7.38) (Z=-2.88), and the depression detection rate decreased(60.9%，30.4%) (χ2=4.29) (P<0.05). There were no statistically significant differences in positive coping, negative coping, selfesteem, social avoidance and distress scores, and depression detection rate between the control group before and after the intervention (Z/χ2=-0.28, -0.42, -1.24, -1.25；1.39, P>0.05). The followup results 1year later showed that there was a statistically significant difference in social avoidance and distress(6.57±6.21,14.16±9.22), and in the detection rates of depression(21.7%,52.2%) between the intervention group and the control group (Z/χ2=2.70,4.57,P<0.05). Conclusions Group counseling integrating teadrinking could improve interpersonal relationships, emotional states, selfesteem levels and coping strategies among college students. Group psychological counseling that incorporates teadrinking can be adopted to improve the mental health status of college students.

BACKGROUND:Satellite cells are a specific population of adult stem cells contained in skeletal muscle that promote the regenerative reconstruction of injured skeletal muscle,but their specific mechanisms are not well established. OBJECTIVE:To review the regulatory role of satellite cells during skeletal muscle regeneration and the mechanism of interaction between satellite cells and their ecological niche signals,aiming to provide new research ideas and perspectives based on the summary of existing knowledge. METHODS:Web of Science,PubMed,CNKI,WanFang,and VIP databases were searched for literature published between January 2002 and June 2022.English search terms were"muscle,skeletal muscle,muscle injury,stem cells,satellite cells,muscle repair".Chinese search terms were"skeletal muscle,skeletal muscle regeneration,skeletal muscle reconstruction,satellite cells,ecological niche".The 66 included papers were organized and analyzed. RESULTS AND CONCLUSION:(1)Satellite cells exist in skeletal muscle and contribute to both the formation of new muscle fibers after injury and the effective growth of existing adult muscle fibers.(2)After the activation of quiescent satellite cells in satellite cells,the steps of satellite cell proliferation,differentiation and fusion to form muscle fibers during skeletal muscle regeneration are influenced by their intrinsic regulatory effects of different mechanisms.(3)Satellite cells can interact with myofibers,extracellular matrix,skeletal muscle junctions,fibroblast progenitor cells,immune cells and endothelial cells in the ecological niche signal to promote satellite cell activation,proliferation and differentiation to achieve effective skeletal muscle regeneration.(4)Possible breakthroughs in future research include:the division pattern of satellite cells in the body;the mechanisms regulating satellite cell transfer;the specific timing of satellite cell differentiation or self-renewal in vivo;and the interaction mechanisms between satellite cells and skeletal muscle junctions.(5)This review may provide some theoretical reference values for the field of injury reconstruction of skeletal muscle and its innovation.

Responses to sedatives, analgesics and muscle relaxants vary among patients under general anesthesia, which could be ascribed to the disparities of clinical characteristics and genetic factors of individuals. Accumulating researches have indicated that gene polymorphisms of the receptors, transporters and metabolizing enzymes associated with anesthetics play a considerable role in their efficacy. However, a systematically summarized study on the mechanisms of gene polymorphisms on pharmacodynamics and pharmacokinetics of anesthetics is still lacking. In this paper, the recent researches on pharmacogenomics of sedatives, analgesics and muscle relaxants are comprehensively reviewed, and the contributions and mechanisms of polymorphisms to the differences of individual efficacy of these drugs are discussed, so as to provide guidance for the formulation of a rational anesthesia regimen for patients with various genotypes.

Non-small cell lung cancer is the main cause of cancer death in the world, and its incidence is increasing year by year, seriously endangering human health. Early non-small cell lung cancer is generally difficult to be detected based on symptoms and signs. Therefore, accurate pathological diagnosis and accurate prediction of prognosis are crucial for formulating the best treatment plan for non-small cell lung cancer patients and improving their survival. The application of artificial intelligence in the diagnosis and treatment of non-small cell lung cancer has shown good performance and great potential effect. This paper introduces the research progress of artificial intelligence in predicting the classification, staging, genomics and prognosis of non-small cell lung cancer.

Objective:To evaluate the efficacy and safety of modified FC/ATG pretreatment in the treatment of severe aplastic anemia(SAA).Methods:From June 2012 to June 2020, clinical data of 64 patients with severe aplastic anemia undergoing allogeneic hematopoietic stem cell transplantation with modified FC/ATG(Flu 30 mg·m -2·d -l, -5~-2 d、CTX 50 mg·kg -1·d -1~-2 d、ATG: 2.5 mg·kg -1·d -1, -5~-2 d) pretreatment were retrospectively analyzed.There were MSD-HSCT ( n=29) and Haplo-HSCT ( n=35). Results:One patient died of intracerebral hemorrhage before transplantation and the remainders were completely implanted.During a median follow-up period of 14.5(1-95) months, overall survival (OS) rate of 92.2%.It was significantly higher than OS rate of 67.2% in the treatment of SAA by foreign pretreatment regimens containing low-dose TBI.And pretreatment scheme containing FC+ BU/TBI had an OS of slightly >91.3% in the treatment of SAA.The 3-year OS rates were 85.7% and 93.5% in Haplo-HSCT and MSD-HSCT groups ( P=0.058). The OS rate of SAA Haplo-HSCT/MSD-HSCT group was similar to that of " Beijing Protocol" (BU/CY+ ATG) (89%, 91%). The viral infection rates of EB and CMV were significantly higher in haplo-HSCT group than those in MSD-HSCT group and inter-group difference was statistically significant ( P<0.05). However, univariate analysis showed that two groups had no effect on survival time ( P=0.403, P=0.132). Univariate analysis showed that survival time was significantly associated with the presence of Ⅲ-Ⅳ° aGVHD and the presence of severe complications ( P=0.007, P=0.001). Further multivariate analysis revealed that severe complication was an independent risk factor for survival ( P=0.003). Conclusions:The efficacy of improved FC/ATG pretreatment in the treatment of SAA in MSD-HSCT or Haplo-HSCT is higher than other domestic and international pretreatment schemes in OS rate, safety and effectiveness.Onset of severe complication and association with Ⅲ ~ Ⅳ ° aGVHD are the influencing factors for patient survival.The efficacy of Haplo-HSCT group is similar to that of MSD-HSCT group.It may be employed as an alternative donor for SAA patients without fully congruent donors.

Objective:To compare the effects of two pretreatment schemes on the efficacy, gonad and reproductive function of haploid hematopoietic stem cell transplantation recipients with severe aplastic anemia(SAA).Methods:The data of 73 patients with SAA who underwent haploid hematopoietic stem cell transplantation were analyzed retrospectively.The pretreatment scheme was divided into Fludarabine+ Cyclophosphamide+ Antithymocyte globulin group(FC lowATG group, 45 cases)and Busulfan+ Cyclophosphamide+ Antithymocyte globulin group(Bucy/ATG group, 28 cases). The changes of blood cell implantation time, follicle stimulating hormone(FSH), luteinizing hormone (LH), estradiol and testosterone were compared between the two groups. Results:there was no significant difference in blood cell implantation time between the two groups( P=0.096; P=0.133). The levels of FSH and LH in female recipients in Bucy/ATG group were higher than those in FC lowATG group, and the level of estradiol was lower than that in FC lowATG group.There were significant differences between the groups(all P<0.05). The pregnancy or fertility rate of female recipients in Bucy/ATG group was lower than that in FC lowATG group(all P<0.05). There was no significant difference in FSH, LH, testosterone and fertility between the two groups(all P>0.05). There was no significant difference in 2-year overall survival rate and failure free survival rate between the two groups( P=0.091; P=0.084). Conclusions:FC lowATG may be an effective pretreatment scheme for haploid hematopoietic stem cell transplantation in SAA with less damage to gonad and reproductive function.

Objective To evaluate the effect of conversion from mycophenolic acid (MPA) to mizoribine (MZR) in renal transplant recipients with gastrointestinal tract (GI) symptoms.Methods A total of 355 renal transplant recipients with GI symptoms caused by MPA administration were enrolled from April 2015 to March 2017 in 25 different renal transplant centers in China.The symptomatic improvement of GI before (baseline) and after conversion to MZR (1,2,4 weeks) was assessed by each item of GI symptoms indication.In addition,the efficacy and safety of the conversion therapy during 12 months were determined.Results Patients showed improvement in GI symptoms including diarrhea,abdominal pain,abdominal distention and stomachache after conversion to MZR 1,2,4 weeks (P＜0.05).In patients with different severity of diarrhea,conversion to MZR therapy significantly improved diarrhea (P＜0.05).During 12 months,no patient experienced clinical immune rejection.We did not observe any infections,leucopenia and other serious side effects.Conclusion MZR could markedly improve GI symptoms caused by MPA administration in renal transplant recipients.

Objective To observe the clinical effects and safety of sodium valproate combined with decitabine for treatment of myelodysplastic syndrome (MDS). Methods Forty-two patients with MDS were enrolled in department of hematology in Shanxi Dayi Hospital from February 2012 to February 2017. According to random number table, the patients were divided into the control group (21 cases) and the experimental group (21 cases). The patients in the control group received decitabine at the dose of 20 mg·m-2·d-1, and intravenous infusion was completed in 2 hours, continuous therapy up to 5 days, 4 weeks as a course; the patients in the experimental group received combined medication, orally given sodium valproate 0.2 g once, 3 times per day. One week later, the dosage was added to 0.4 g once, 3 times per day. Both groups received at least 4 courses of treatment. The treatment was stopped when serious adverse reactions or obvious disease progression occurred. The bone marrow smear was rechecked every 4 weeks after treatment to evaluate the efficacy. The expressions of ASXL1, DNMT3A and TET2 in bone marrow cells were detected by fluorescence quantitative PCR before and after treatment. Results The total treatment response rate of the experimental group and the control group were 76.2 % (16/21) and 57.1 % (12/21) respectively, and there was statistically significant difference (P< 0.05); the total remission rate of the two groups was 47.6 % (10/21) and 38.1 %(8/21) respectively, and there was no significant difference (P> 0.05). All patients had slight adverse reactions, and the adverse reaction rate was 42.9 % (9/21) and 38.1 % (8/21), and there was no significant difference (P>0.05). The content of TET2 mRNA and DNMT3A mRNA after treatment in both groups were decreased compared with the expressions before treatment, and there were significant differences (P<0.05). However, there was no significant difference between the two groups after treatment (P> 0.05); the content of ASXL1 mRNA had no obvious change in the control group and a dramatic decrease in the experimental group compared with that before treatment (P<0.05). Conclusion Sodium valproate combined with decitabine has favorable effects and mild adverse reactions for treatment of MDS, besides, it can influence the expressions of TET2, DNMT3A and ASXL1.
