Tuberous sclerosis complex (TSC) is a rare autosomal dominant disorder.Primarily involving the skin and central nervous system, it also impacts the heart, lungs, kidneys, and other organs.The vast majority of TSC patients may experience neuropsychiatric symptoms during their lifetime, including behavioral, mental, intellectual, academic, neuropsychological, and psychosocial disorders, which are collectively referred to as TSC-associated neuropsychiatric disorders(TAND).The TAND Checklist is a screening tool designed to identify potential neuropsychiatric disorders by facilitating dialogues between TSC patients, their families, and clinicians.This article focuses on the concept and research history of TAND and the application of the TAND Checklist, contributing to the comprehensive and systematic clinical evaluation and understanding of the prognosis of children with TAND.

OBJECTIVETo investigate the correlation between smoking status and carotid plaque in rural population residing in Eastern part of China.

METHODSBetween July and September of 2013, an epidemiological survey was carried out in residents aged 40 or above men who were enrolled randomly in rural areas of Anqing, Anhui province and Lianyungang, Jiangsu province. The data on epidemiological characteristics including smoking status, physical examination were collected using standardized protocol, and carotid ultrasonography was applied to examine the incidence of carotid plaque among never smokers, former smokers and current smokers. Logistic regress analysis was performed to determine the effect of smoking on carotid plaque.

RESULTSIn the study, a total of 625 male participants were included in the study. 51.4% (321 cases) were current smokers, 21.3% (133 cases) were former smokers, and 27.4% (171 cases) were never smokers. 32.0% (200/625) had carotid plaque. The incidence of carotid plaques was significantly higher in current smokers (35.2%, 113/321) than that in never smokers(23.4%,40/171) (χ(2) = 7.26, P = 0.007) and the incidence in former smokers (35.3%, 47/133) was also higher than that in never smokers (23.4%, 40/171) (χ(2) = 5.23, P = 0.022). Multiple logistic regression analysis showed that current cigarette smoking is significantly associated with the increased risk of carotid plaque (OR = 1.84, 95% CI: 1.13-2.98, P = 0.014) in comparison with never smokers, and there was an interaction between current smoking and age in association with carotid plaque. Compared with the young (≤60 years old) and never smoking group (8%, 3/40), prevalence of carotid plaque among the elderly (>70 years old) and smoking group (55%, 31/56) was significantly higher (OR = 8.06, 95% CI: 2.07-31.45) after adjusting for age, systolic blood pressure, diastolic blood pressure, blood glucose, total cholesterol, triglyceride high-density lipoprotein, body mass index, drinking and regional differences.

CONCLUSIONIt found that cigarette smoking was associated with increased risk of carotid plaque in rural elderly population residing in Eastern part of China.

Objective To document the impact of conversion to mycophenolate mofetil (MMF)at different time points after transplantation on the renal function of renal function.Methods A longterm,multicenter,non-interventional and observational study was done.Two cohorts were included:One was Switch cohort (340 cases) including renal allograft recipients who switched to MMF at least 6 months after renal transplantation and followed up for 4 years after switch; The other was Stay cohort (123 cases),including renal allograft recipients who received MMF treatment after transplantation and followed up for 4 years after enrollment.Results GFR values of patients in Switch cohort was significantly increased after switch,and the change in GFR slope was 3.1 mL· min-1 · year-1 (P＜0.01).GFR values of patients in Stay cohort kept steady before and after enrollment,and the change in GFR slope was 0.44 mL·min-1 ·year-1 (P＞0.05).Statistically significant difference in the onset time of GFR decline (defined as 20％ decline from the baseline) was observed among subgroups within Switch cohort (P＜0.01),but there was no significant difference among subgroups within Stay cohort (P＞0.05).Stay cohort was 12％ higher than in Switch cohort every year.Conclusion Conversion to MMF ＞6 months or even many years after transplantation can obviously improve the renal function of recipients.The earlier conversion can benefit improvement of the renal function.

Objective To discuss the operative procedures and clinical result of posteromedial and posterolateral approaches in treatment of posterior condylar tibial plateau fractures. Methods From January 2006 to June 2008, 21 patients of posterior condylar tibial plateau fractures were treated by posteromedial and posterolateral knee approaches. There were 12 males and 9 females. The age ranged from 28 to 68 years, with a mean of 39.5 years. Of the patients, 13 had resulted from a traffic accident and 8 had caused by a fall. As for the state of posterior condylar tibial plateau fractures, 7 patients had a medial condylar.fracture, 8 patients had a lateral condylar fracture and 6 patients had a bilateral condylar fracture. Results A follow-up lasted 12-24 months (mean 16.2 months ) in 21 patients. There was no infection, no varus or valgus of the knee, no nerve injuries and loosening or breakage of the screw. All cases had attained bone union. According to the Rasmussen functional scoring, the results were excellent in 12, good in 7 and fair in 2. The excellent and good rate of clinical results was 90.5%. Radiologic results were graded with the Rasmussen score to evaluate the reduction of fracture. There were excellent in 13, good in 7 and fair in 1. The excellent and good rate of clinical results was 95.2%. Conclusion Posteromedial and posterolateral approaches can facilitate the reduction and fixation for posterior condylar tibial plateau fractures. It has many advantages such as good exposure, less invasion and the excellent clinical results.

Objective To explore the feasibility of mediating recipient lymphocyte reaction with donor dendritic cells (DCs) in renal allograft recipients. Methods Donor bone marrow monocytes (BMMCs) were isolated and cryopreserved in liquid nitrogen before kidney transplantation. At 0 day, 1month,3 month, 6 month and 9 month post-operation, CD34+ cells which were isolated from frozen BMMCs and cultured into DCs as well as the peripheral blood lymphocytes (PBLs) of donors were used as the stimulating cells to the PBLs of recipients and healthy volunteers. The number of viable DCs from frozen- and room temperature-preserved BMMCs was counted and the reactions of recipients'and healthy volunteers' lymphocytes to DCs and donor PBLs were measured. Results 6. 8 × 107BMMCs were isolated from each 10 ml of donor bone marrow on average while (4. 10 ± 0. 58) × 105CD34+ cells were isolated by magnetic active cell sorting (MACS). There was no significant difference in the isolating rate of recovered CD34+ cells at each observation point postoperatively. The percentage of viable BMMCs and CD34+ was decreased significantly at 1 month after surgery, then, decreased slowly and progressively. The decreasing rate of BMMCs was higher than CD34+. The rate of viable DCs was maintained stable (93. 2%-94. 8% ) in each group. The reactions of recipients' and healthy volunteers' lymphocytes to DCs were stronger than those to donor PBLs (P＜0. 05). The reactions of healthy volunteers' lymphocytes to DCs were maintained stable while those of recipients' were fluctuating. Conclusion Bone marrow-derived DCs are superior to PBLs in mediating long-term lymphocyte reaction after kidney transplantation due to their stable viability and stimulating ability to lymphocytes. Only once collection of a small quality of bone marrow of donors is needed to meet the demand of immune monitoring at any time after transplantation.

ObjectiveTo explore the feasibility of mediating recipient lymphocyte reaction with donor dendritic cells (DCs) in renal allograft recipients to guide individualized inmunosuppressive therapy. Methods From Jan. 2008 to Jan. 2010, 30 recipients received living related kidney transplantation were successively and divided into 2 groups according to the strategies of the correction of the dosage of immunosuppressant, 15 in each group. The strategy of immunosuppressive therapy in both groups was Tac + MMF + Pred. The correction of the dosage of immunosuppressant in experimental group was conducted by recipient lymphocyte reaction with donor DC (LR) combined with Tac and MPA blood concentration monitoring. Only blood concentration monitoring of drugs was applied in control group. Examinations of liver and renal function, blood and urine routine as well as blood sugar were done monthly for 1 year. ResultsDuring the follow-up period, the rate of acute rejection in experimental group and control group was 13. 3 ％ and 46. 7 ％ respectively (P＜0. 05) ;the rate of infection in experimental group and control group was 6. 7％ and 40. 0％ (P＜0. 05)respectively; the adverse reaction rate in experimental group and control group was 13. 3％ and 46. 7％(P＜0. 05). There was no significant difference in the serum creatinine level between the two groups at each observation point. ConclusionThe application of combined recipient LR with donor DC and blood concentration monitoring of drugs in individualized irnmunosuppressive therapy is more comprehensive and accurate.
