Objective To detect the therapeutic effectiveness of electro-acupuncture combined with Leitoufenggranules for primary trigeminal neuralgia.MethodsA total of 60 patients with PTN were randomly divided into the control group and the treatment group (30 in each group). Control group received Carbamazepine, and the treatment group received the electro-acupuncture combined withLeitoufeng granules. Both groups were treated for 15 days as a period of treatment with 3 treatments in total. The outcomes were S hort form of the McGill Pain Questionnaire (SF-MPQ), painratingindex (PRI), the number of word feature (NWC), the present painindex (PPI), the Visual Analogue Scale (VAS) the clinical effect rate and recurrence rate. Results After treatment, compared with the control group, the effect rate (96.67%vs. 70.00%,χ2=5.880,) in the treatment group showed significantly higher (P=0.015). Compared with the control group, PRI (0.20 ± 0.47 vs. 3.33 ± 4.65,t=3.592), NWC (0.20 ± 0.48vs. 1.40 ± 1.87,t=3.345), VAS (0.20 ± 0.48vs. 1.27 ± 1.66, t=3.321), PPI (0.17 ± 0.38vs.0.90 ± 0.99,t=3.771) and the total score (0.79 ± 1.83vs. 6.90 ± 9.05,t=3.602) in the treatment group were significantly lower (P<0.01). In the follow-up of 3 months, compared with control group, the recurrence rate (10.0%vs.56.6%,χ2=12.675) in the treatment group significantly lower (P<0.01). Conclusion As to the treatment of primary trigeminal neuralgia, the effect of acupuncture combined with Leitoufeng granules was superior to the Carbamazepine.

Objective To investigate the alteration of Toll-like receptor (TLR) 2 and 9,myeloid cell differentiation 88 (MyD8),interleukin-2 (IL 2),interferon-γ(IFN γ) and interleukin-10 (IL-10) expression in spleen lymphocytes of cytomegalovirus (CMV) infected newborn murine.Methods Sixty-four neonatal mice were randomly divided into control group and CMV infected group (32 mice in each).Mice in CMV infected group were injected intraperitoneally with 20 μl CMV suspension (tissue culture infections dose 50 of 104.31 U/0.1 ml) at 4 6 hours after birth to create the systematic CMV infection models.At 3,5,7 and 10 days old,eight mice randomly selected from each group were sacrificed.Polymerase chain reaction was applied to detect CMV-DNA in liver,spleen,heart,lung,kidney and salivary glands of 7 day old mice.Western blot was used to measure the protein expression of T1R 2,9 and MyD88 in spleen lymphocyte,and enzyme linked immunosorbent assay was used to test the levels of IL-2,IFN-γand IL-10 in supernatant of spleen lymphocyte from 3,5,7 and 10-dayold mice.Independent samples t test and Pearson correlation analysis were applied as the statistical methods.Results On the 7th day after CMV infection,the protein expression of TLR 2,9 and MyD88 in spleen lymphocyte in CMV infected group increased to the maximum level (1.06±0.09,1.19±0.03 and 0.89±0.07),which were higher than those in control group (0.47±0.04,0.71 ±0.02 and 0.43±0.03),the differences were statistically significant(t=21.69,50.40 and 42.06,P＜0.01,respectively).In CMV infected group,expression of IL-2 decreased to the lowest level on the 7th day after CMV infection [(16.9±7.3) pg/ml],IFN γ reached its peak level on the 5th day [(242.9±8.4) pg/ml] and IL-10 increased since the 5th day [(62.4±11.1) pg/ml],there were statistically significant differences as compared with control group [(51.9± 10.8) pg/ml,(135.3±10.5) pg/ml and (36.3±5.1) pg/ml](t=15.74,19.00 and 9.60,P＜0.05,respectively).There was a negative correlation between TLR2,TLR9,MyD88 protein expression and IL-2 level (r =0.978,0.960 and-0.979,all P＜0.01,respectively) and a positive correlation between TLR2,TLR9,MyD88 protein and IL-10 level (r =0.954,0.914 and 0.892,P ＜ 0.01,respectively).Conclusions In the early phase of CMV infection (within 7 days),immunity is activated through TLR/MyD88 signal pathway resulting anti-infection effect.However,after the 7th day,Th1/Th2 cellular immunity imbalance allows virus to replicate easily.

Accurate placement of pedicle screws is a key factor of spinal surgery. Investigation of a new real-time intra-operative monitoring method is an important area of clinical application research which makes a contribution to planting pedicle screw accurately. Porcine spines were chosen as experimental objects. The changes of reduced scattering coefficient (μ'(s)) along normal puncture path, medial perforation path and lateral perforation path were measured and studied. A conclusion is drawn that there are two distinct peaks throughout the puncture process, appearing at the junction of cancellous bone and cortical bone, at the beginning and at the end, respectively. The reduced scattering coefficient is proved to be a good monitoring factor which can identify whether the screw is about to reach the critical position of the spine puncture. Moreover, the variation provides an important reference for spinal surgical navigation process.
