Objective To evaluate the effectiveness of training management applying character color theory in patients with peritoneal dialysis on the compliance and dialysis effect. Methods Of 95 patients undergoing catherization for peritoneal dialysis from January 2013 to May 2014 in the peritoneal dialysis center,72 patients accepted character color psychological questionnaire designed by Le Jia for character color analysis.72 patients were divided into matched control group and experimental group according to their choice with red, yellow, blue, green character color, 36 cases in each group. The control group adopted the traditional training way of accepting 7 days′training course teached by the professional nursers,one follow- up management each month. According to the difference of character color,the experimental group were given different education training courses, interactive learning, and follow- up time. After 6 months′follow- up, the two groups adopted peritoneal dialysis self management behavior questionnaire designed by Liu Pengfeng and self- efficacy scale designed by education research center for chronic disease in Amercian Stanford University. The score of self management ability and self- efficacy and the change of load capacity, blood pressure, dialysis adequacy and biochemical indicators of the two groups were analyzed. Results In the control group and experimental group,the score of self management ability and self- efficacy and the level of dialysis adequacy were statistically significant, respectively, (5.64±1.57) points vs. (6.75±1.32) points;(5.22±1.48) points vs. (6.69±1.43) points; 1.64±1.64 vs 1.85±0.13.Z and P values were respectively -2.969, -3.828, -6.361, and 0.003, 0.000, 0.000.Edema happened in the control group was 24 cases, and 11 cases in the experimental group. P and χ2 values were 0.013 and 10.017.Systolic blood pressure and di-astolic blood pressure were respectively (147.78±15.69) mmHg (1 mmHg=0.133 kPa) vs.(135.39±9.01) mmHg,(95.86±7.50) mmHg vs. (83.94±7.46) mmHg in the two groups. Z and P values were respectively -3.843, -5.666, and 0.000, 0.000.There was significant difference between the experimental group and control group. Conclusion The education and training applying character color feature in patients with peri-toneal dialysis can mobilize the initiative of self management, improve the patients' self- care competency and self-efficacy, enhance patients′compliance, that can improve the effect of peritoneal dialysis.

Objective To investigate the therapeutic effects of rapamycin (RAPA) on concanavalin A (ConA)-induced acute autoimmune hepatitis in a mouse model and to analyze the possible mechanism.Methods Thirty eight-week-old female C57BL/6 mice were randomly divided into three groups including control group,ConA model group and ConA + RAPA treatment group.The levels of alanine transaminase (ALT) and aspartate aminotransferase (AST) in serum samples were measured after injection of mice with ConA for 24 hours for assessing the liver function.Hematoxylin-eosin (HE) staining was used to observe the hepatic pathological changes in mice.Splenocytes were harvested 24 h after ConA injection for the detection of the percentages of splenic DCs,CD4+T,CD8+T and CD4+ Foxp3+ Treg cells as well as the expression of co-stimulatory molecules (CD40,CD80 and CD86) on DCs by using flow cytometry.Results The levels of ALT and AST in mice from the RAPA treatment group were significantly lower than those of the ConA model group.Results of the HE staining assay showed that the liver damages in RAPA treated mice were less severe than those in mice from the ConA model group.Compared with mice form the ConA model group,those treated with RAPA showed decreased percentages of splenic CD4+ and CD8+ T cells,inhibited expression of CD80 and CD86 on splenic DCs,but increased percentages of splenic CD4+ Foxp3+ Treg cells.No statistically significant differences in the percentages of splenic DCs and the expression of CD40 were observed between the RAPA treatment group and the ConA model group.Conclusion The immunosuppressive effects of RAPA on mice with ConA-induced hepatitis might be achieved through the regulation of immune cells including DCs and T cells in spleen tissues.This study might pave the way for further investigation on the prevention and treatment of autoimmune hepatitis.

BACKGROUND:A great development has been achieved in essential research on tissue engineered cartilage. However, its real application in otolaryngology has been rarely reported. It is faced with the topic to explore the simple and convenient method of repairing laryngeal cartilage by tissue engineering technique. OBJECTIVE:To compare the effect of porous spongy poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) seeded with chondrocytes or using senior tissue engineered cartilage in repairing al ogenic thyroid cartilage defects.METHODS:Chondrocytes at passage 3 were harvested from infant rabbits within 3 days. Porous spongy poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) seeded with chondrocytes composites were made by tissue engineering technique. The chondrocyte-poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) composites were co-cultured in vitro to form junior tissue engineered cartilage. And then respectively used for repairing the thyroid cartilage defects and directly transplanted with junior tissue engineered cartilage (experimental group A, n=5), or firstly the junior tissue engineered cartilage to be implanted subcutaneously for a period of time to further maturity for relative senior tissue engineered cartilage and secondly to be transplanted (experimental group B, n=5) into adult New Zealand white rabbits. Simple poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) sponge scaffold (control group A, n=4) and chondrocyte suspensions(control group B, n=4) were used as reparative materials in defect areas as control groups. Final y, the reparative effect was respectively studied grossly and histological y at 4 weeks (experimental group B) and 8 weeks (experimental group A, control group A and control group B) after transplantation. RESULTS AND CONCLUSION:The cartilage defects were wel repaired in the experimental groups. It was smooth between the reparative area and original cartilage without dents and defects. Both were similar grossly. But few chondrocytes at interfacial region between the reparative area and original cartilage and poor matrices were observed in the experimental group A. A Few chondrocytes and more matrices were observed in the experimental group B. Inflammatory cellinfiltration was not obvious in two experimental groups. Control groups showed soft tissue of dark-red color accompanied with local concave in gross specimens. Histological examination and special staining showed there were no cartilage-like structure and secretion of matrix components. The results showed that it is possible to repair thyroid cartilage defect using junior tissue engineered cartilage directly or junior tissue engineered cartilage after in vitro implantation in al ograft rabbits with immunity, and the immunoreaction is not obvious;in the same period, the repairing effect of mature tissue engineered cartilage is better than that of junior tissue engineered cartilage. However, application of junior tissue engineered cartilage directly can save time, costs, workload and operational link, and avoid the pain from secondary skin surgery, which is one of the more practical approaches.

Objective To investigate the factors affecting the isolation of fastidious bacteria such as Streptococcus pneumoniae and Haemophilus influenzae from lower respiratory tract specimens in children.Methods A total of 210 lower respiratory tract specimens from children were collected and inoculated on both blood agar plate and chocolate agar plate 0.5 h,2 h,6 h,12 h,and 24 h after collection.The effect of specimen turnaround time,transport medium,and inoculation medium on the isolation of fastidious bacteria was studied.Results The results of 200 qualified specimens showed that the isolation of S.pneumoniae and H.influenzae significantly decreased with the increasing of specimen turnaround time (P＜0.05),but no significant difference was observed between 0.5 h and 2 h timepoints.The isolation of fastidious bacteria in semi-solid medium was non-significantly higher than the other two transport medium (P＞0.05).No significant difference was found in the isolation and growth ofS.pneumoniae and H.influenzae on different inoculation media (P＞0.05).Conclusions The appropriate specimen turnaround time,transport medium,and inoculation medium are important for improving the isolation of fastidious bacteria from lower respiratory tract in children.

Objective:To investigate diagnosis and treatment methods of nontuberculous mycobacteria (NTM) infections related to cosmetic surgery.Methods:This study was a retrospective observational study. From January 2015 to December 2023, 24 patients with NTM infections related to cosmetic surgery meeting the inclusion criteria were admitted to Shenzhen Hospital of Southern Medical University and Northern Theater Command General Hospital, all of whom were female and aged 29-51 years. Among them, 20 cases underwent lipolysis needle injection surgery, 2 cases underwent facial contouring surgery, 1 case underwent foreign body injection, and 1 case underwent wrinkle removal surgery. The clinical manifestations of infections caused by NTM included scattered dark purplish subcutaneous nodules at the infection site with unclear boundaries, thinning of the skin on the surface of the nodules and ulceration, and powdery-white fish meat like tissue and a small amount of light yellow exudation being seen at the ulceration. In order to improve the detection rate of NTM, bacterial culture of wound exudation combined with solid tissue samples, multiple bacterial cultures, and extending culture time were performed. All patients were treated with damage control debridement on the infected site and comprehensive treatment including the use of antibiotics based on the results of drug sensitivity tests. The types of NTM infections, drug sensitivity test results, wound healing time, number of bacterial cultures, and surgical debridement times were recorded. The wound healing was observed during follow-up.Results:The bacterial culture results showed that there were 22 cases of infections with Mycobacterium abscessus and 2 cases with Mycobacterium fortuitum. The drug sensitivity test results showed that the NTM was sensitive to antibiotics such as clarithromycin, amikacin, and doxycycline. The average healing time of the wound was 83.6 days with an average of 2.85 times bacterial cultures on the specimen, and an average of 2.52 times of debridement surgery. Follow up for 6 months to 5 years, all wounds of the patients were healed. Among them, 22 patients had a basically normal appearance with slight scars, while 2 patients had obvious scars and depressions. Conclusions:It is difficult to treat NTM infections related to cosmetic surgery. Damage control debridement for the infected site can ensure wound healing and reduce the damage and postoperative deformities in facial and other cosmetic areas.
