Objective To analyze the clinical effects of individualized comprehensive physiotherapy interventions for temporomandibular disorders (TMD).Methods Data of 307 patients with TMD treated between April 2011 and March 2012 in the authors' department were collected and reviewed.All the patients were treated with individualized comprehensive physiotherapy approach based on the patient's category in research diagnostic criteria for TMD (RDC/TMD),such as patient education,ultrashort-wave diathermy,ultrasound therapy,soft tissue massage,joint mobilization and stabilization exercise.The treatment was administered for 3 weeks.The baseline and endpoint outcome assessment measures were maximum active mouth opening (mm),visual analogue scale (VAS) score and joint clicking (100% before treatment).Results At the end of treatment,the patient's maximum active mouth opening [(36.95 ± 6.59) mm],VAS score (1.21 ± 0.62) and joint clicking [(29 ± 17) %] improved significantly (P < 0.05) compared to baseline.Conclusions Individualized comprehensive physiotherapy interventions can improve symptoms of TMD,such as joint clicking,pain,limited mouth opening.

AIM: To investigate the effect of berberine (Ber) on the activation and proliferation of T lymphocytes and its mechanism of action. METHODS: Whole peripheral blood from normal subjects was stimulated with phytohemagglutinin (PHA) or phorbol ester (PDB) plus ionomycin (Ion) and the expression levels of CD69 and CD25 were evaluated with flow cytometry after the staining with appropriate fluorescent monoclonal antibody. The distribution of cell cycles was analyzed by propidium iodide staining and dead cells by 7-aminoactinomycin live staining. RESULTS: 100 ?mol/L and 50 ?mol/L of Ber had significant inhibition of the expression of CD69 on T cells stimulated with PDB plus Ion or PHA, while effect of 25 ?mol/L Ber was not significant. And as time of action extended, the extent of inhibition decreased. For the expression of CD25, Ber at the concentrations as above all exerted significant inhibitory effect in a dose-dependent manner. Moreover, Ber could block lymphocytes cell cycle progression from G_0/G_1 phase to S and G_2/M phase without phase specificity. Besides, live staining analysis revealed that Ber did not have significant cytotoxicity on lymphocytes. CONCLUSIONS: Ber significantly inhibits the expression of early and mid activation antigens of T cells and also blocks the progression of lymphocytes cell cycles. These results suggest that Ber exerts immunosuppression effect through inhibiting the activation and proliferation of T cells.

AIM: To construct the mammalian cell expression vector for enhanced green fluorescent protein (EGFP) and HLA-A*0201 fusion protein and analyze its expression and subcellular localization in the transfected K562 cells. METHODS: The HLA-A*0201 cDNA was cloned by RT-PCR and the gene was inserted into pEGFP-N1 to construct a vector for the fusion protein. The expression of the fusion protein in K562 cells transfected with the vector was evaluated by flow cytometry and its subcellular localization was investigated by confocal microscopy. RESULTS: The full-length encoding region of HLA-A*0201 cDNA was cloned from two HLA-A2 positive donors and the expression vector for the HLA-A*0201-EGFP fusion protein was constructed by PCR using a primer pair to introduce a Kozak sequence before ATG and the stop codon was deleted. Five hours after K562 cells was transfected with the vector, the expression percentages of HLA-A*0201 and EGFP were 25.12?2.26 and 27.37?3.59, respectively and no significant increase was observed after 24 h. The fusion protein was predominantly located on the membrane with low level distribution within the cells. In contrast, no HLA-A*0201 but only EGFP was detected in the empty vector transfected K562 cells and the EGFP was dispersed within the cells. CONCLUSIONS: The expression vector for HLA-A*0201-EGFP fusion protein was constructed and the fusion protein expressed in K562 cells was primarily distributed on the membrane. The results suggest that the transfected K562 cells are potential antigen-presenting cells.

Objective To investigate the effect of taurine transporter in the process of protection of brain edema in rats with severe traumatic head injury. Methods A total of 24 Male Sprague-Dawley rats were randomly divided into 4 groups. Except the control rats (Group Sham), all other three groups were subjected to lateral fluid percussion head injury. The TBI (Traumatic brain injury) models (Group TBI) and surgical control rats (Group Sham) were injected with saline through caudal vein after surgery, while the Taurine prevention and Taurine treatment models (Group Pre Tau and Group Tau) were injected with 120 g/L taurine solution before or after surgeries respectively. Water content in each brain, mRNA and protein expres?sion of aquaporin 4 and taurine transporter in the injured rat brain hemispheres were all evaluated over the time course of the study (7 d) in each group. Results Compared with rats in Group Sham, water content in each brain increase, mRNA tran?scription and protein expression of AQP4 were both up regulated but the mRNA transcription and protein expression of TauT were both down-regulated in rats in TBI group. Compared with rats in TBI group, brain water content, mRNA transcription and protein expression of AQP4 all decrease while mRNA transcription and protein expression of TauT all increase in rats in Pre tau and Tau groups. There is no statistical difference of TauT expression between rats in pre-tau group and Tau group. Conclusion Taurine exert its neuron protection role through draining water content from brain and down regulating expres?sion of AQP4 but rising expression of TauT after TBI.

AIM: To explore the inhibitory effect of oxymatrine (OMT) on the allergic contact dermatitis (ACD) stimulated by dinitrofluorobenzene (DNFB) and its effects on the proliferation of the lymphocytes. METHODS: ① An ACD mouse model was established by stimulation with DNFB, and then the mice were injected intraperitoneally with different dosages of OMT, PBS and hydrocortisone (HCT) respectively, the swelling degree of their auricles was examined. ② Carboxyfluorescein diacetate, succinimidyl ester (CFDA-SE) dye and flow cytometer were used to examine the fluorescence intensity changes of lymphocytes stimulated by polyclonal stimulator ConA and OMT. RESULTS: ① compared with PBS group, OMT possessed the strong inhibitory effect on the ACD caused by DNFB in a dose-dependent manner, and its inhibitory effect was equivalent to the HCT of the same dosage with fewer side effects. ② In vitro experiments proved that OMT (500, 125 and 31 mg/L) had the ability to restrain the proliferation of lymphocytes of mouse. CONCLUSION: OMT possesses an inhibitory effect on the ACD induced by DNFB, and OMT is a kind of immunosuppressor.

AIM: To investigate the details of CD4 + T cell polarized to Th1/Th2 in vitro . METHODS: After isolated the PBMCs and blood-plasma from adult human peripheral blood by Ficoll-Hypaque centrifugation, the PBMC culture procedure with or without the self-blood -plasma was applied to polarize T cells in vitro , these cells were polarized by PHA(20 mg/L),non-PHA respectively. The polarized rates of Th cell after 24 h,48 h,72 h were estimated respectively by flow cytometry following two-color immunofluorescent staining. RESULTS: CD4 +T cell would polarize to Th1/Th2 two subsets after self-cytokines and PHA activation in vitro . The polarized rates of T cell after cultured for 24 h,48 h and 72 h were (13.28%?1.59%)/(12.70%?1.65%),(17.19%?1.03%)/(17.50%?1.30%),(19.49%?2.87%)/(18.58%?1.49%) respectively, but the polarized rates of T cell were very low if without self-blood-plasma. The difference between them was significant. The ratios of Th1/Th2 cells were about 1. CONCLUSION: CD4 +T cell from adult human peripheral blood would polarize to Th1/Th2 two subsets in the presence of self-blood-plasma and PHA(20 mg/L) in vitro , and the cell number of Th1 and Th2 would be in balance.
