OBJECTIVETo analyze the relationship between symptoms and signs of temporomandibular disorders (TMD) and the patients' quality of life (QOL).

METHODSA total of 492 TMD patients were included in this study. The clinical examination results were recorded using Fricton index of temporomandibular joint function. "Visual analog scale (VAS) evaluation of QOL disturbance" was designed to quantitate patients' QOL, to evaluate the degree that the patients QOL was affected.

RESULTSChewing, daily life and emotion among all 8 items of QOL were frequently affected by TMD, and joint clicking had the least influence on QOL. Intermittent closed lock had more severe interference with QOL than joint clicking only. Severe and moderate pain or limited mouth opening affected the QOL more severely than mild pain or mild limited mouth opening. The simple linear relationship between Fricton index and patients' QOL was poor (r < 0.4).

CONCLUSIONSPain is the most frequently seen symptom in TMD. TMD could affect patients' QOL, including both physical and social-psychological functions. The results suggest that the patients' QOL as well as TMD symptoms and signs should be considered in the management of TMD.

OBJECTIVETo explore therapeutic effects of modified femoral prosthesis applied in the initial posterior stabilized total knee arthroplasty.

METHODSFrom April 1, 2012 to January 1, 2013, 156 patients with knee osteoarthritis underwent posterior stabilized total knee arthroplasty by the same director of orthopedic surgeon. Sixty-one patients were treated with modified femoral prosthesis, including 7 males and 54 females, with an average age of (68.34 +/- 5.41) years old; and 95 patients were treated with conventional designed femoral prosthesis, including 14 males and 81 females, with an average age of (69.92 +/- 5.11) years old. Indexes including age, body mass index, Insall-Salvati index, type of prosthesis, occurrence rate of patella click syndrome, postoperative line of force of lower extremity and postoperative function of the knee joint were observed and recorded. And American Knee Society (AKS) score was used to evaluate the clinical results.

RESULTSAll the patients were followed up, and the duration ranged from 36 to 56 weeks, with a mean of 45.31 weeks. Among patients in the conventional designed femoral prosthesis group, 7 patients had patella click syndrome, but there was no patient having patellar click syndrome in the modified femoral prosthesis group. Postoperative knee activity of patients in the modified femoral prosthesis group was (110.98 +/- 10.32) degrees, which was better than (107.05 +/- 8.61) degrees in the conventional designed femoral prosthesis group. The AKS score in the modified femoral prosthesis group was 129.79 +/- 9.63 during 21 to 28 days after operation, which was higher than 126.85 +/- 7.79 in the conventional designed femoral prosthesis group.

CONCLUSIONNew designed femoral components are effective to reduce the occurrence rate of postoperative patellar click syndrome and obtain better early functional recovery from knee surgery.

Objective To evaluate the relationship between the amount of grafted cells and the incidence of acute graft versus host disease (aGVHD) after haploid hematopoietic stem cell transplantation (haplo-HSCT). Methods Data of 68 patients who underwent haplo-HSCT from Jan 2009 to Dec 2013 were analyzed retrospectively. Influences of different factors on the incidence of Ⅲ-Ⅳ degree of aGVHD after HSCT were evaluated. Results 68 patients including 42 males and 26 females were 5/10-9/10 HLA match with 19 father donors, 24 mother donors, 16 sibling donors and 9 children donors. 51 patients not suffered Ⅲ-Ⅳdegree of aGVHD included 32 males and 19 females with the mean age of 20 years old (5-55 years old). 17 patients sufferedⅢ-Ⅳdegree of aGVHD including 10 males and 7 females with the mean age of 23 years old (5-54 years old). There were no significant differences in the amount of the grafted mononuclear cells (MNC) and CD34+cells, and the white blood cell counts (WBC) and platelet count (Plt) recovered time between two groups (P>0.05). However, MNC number was related to CD34+cell number (P<0.05) and WBC recover time (P<0.05), and the CD34+cells number was related to WBC and Plt recover time (P< 0.05). Conclusion The incidence of Ⅲ-Ⅳ degree of aGVHD is unrelated to the amount of grafted MNC, and CD34+cells.

OBJECTIVE To investigate the effect of new baicalin(BC) metal ions(Co2+,Cu2+, and Ni2+)complexes(BMCs)on ion channels Kv1.4 and Cav3.2. METHODS HEK293 or CHO cells loaded with various ion channels(hERG,Kv1.2,Kv1.3,Kv1.4,Kv1.5,Kv1.6,Kv1.7,Kv1.8,Kir1.1, Kir2.1,KCNQ and Cav3.2)were obtained by stable transfection method. Whole-cell patch-clamp tech?nique was used to record current changes of each ion channel induced by BC and BMC in 10μmoL · L-1. The effect of different concentrations(0.3,1,3,10 and 30μmoL · L-1)of BC-Co and BC-Cu on Kv1.4 and Cav3.2 current was detected by whole-cell patch-clamp technique. RESULTS A model of HEK293 cells or CHO cells that stably expressed various ion channels was obtained. BMCs (BC-Co,BC-Cu and BC-Ni)had some impact on various ion channels,especially on Kv1.4 and Cav3.2. The inhibitory rate induced by BC-Co,BC-Cu and BC-Ni(10 μmol · L-1)was 91%,76% and-10%,respectively,for Kv1.4;and 43%,57%and-14%,respectively,for Cav3.2. IC50 of BC-Co was 1.69 and 0.81μmoL·L-1 for Kv1.4 and Cav3.2. IC50 of BC-Cu was 1.66 and 0.58μmoL · L-1 for Kv1.4 and Cav3.2. CONCLUSION BC-Cu and BC-Co concentration-dependently inhibit Kv1.4 and Cav3.2 ion channels.
