OBJECTIVE: To evaluate the efficacy of chinese traditional treatment after functional endoscopic sinus surgery (FESS) for patients with chronic sinusitis. METHOD: Eighty-eight cases of patients with chronic sinusitis were randomly divided into control group and treatment group after FESS and followed for 3 months. The control group received routine treatment. The treatment group received Chinese traditional treatment on the basis of routine treatment. VAS scores, Lund-Kennedy scores and Lund-Mackay scores were employed to conduct the subjective and objective assessment, comprehensively evaluate the clinical efficacy before and after treatment. RESULT: (1) After 3 months of treatment, the two groups of VAS scores and Lund-Mackay scores were significantly improved before treatment (P<0. 05). (2)After 3 months of treatment, the effectiveness of the control group was 81. 8%, treatment group was 97. 7%, the difference was statistically significant(P<0. 05). CONCLUSION Chinese traditional treatment after FESS can reduce postoperative mucosal edema and promote the postoperative recovery of sinus mucosal inflammation, is effective in preventing the recurrence of postoperative.

OBJECTIVETo probe into the relationship of different needle-retained time with therapeutic effects.

METHODSForty experimental rats were evenly randomized into 5 groups, electroacupuncture (EA) at "Zusanli" (ST 36) for 5 min, 15 min, 30 min and 60 min groups, who received EA for 5, 15, 30 and 60 min respectively, and a control group who did not receive EA. Nicotinamide adenosine dinucleotide phosphate diaphorase (NADPH-d) method and computer image analysis system were used to detect the meangray of nitric oxide synthase (NOS) positive neurons in the septum.

RESULTSNOS positive neurons in the septum did not change as the EA for 5 min group compared with the control group (P > 0.05); the number of heavily staining NOS positive neurons increased significantly (P < 0.05) and the meangray of the NOS positive neurons significantly decreased (P < 0.01) in some septal subnuclei (lateral septum, and medial septum, vertical diagnonal band) after EA for 15, 30, 60 min as compared with the control group, and the numbers and the meangray of the NOS positive neurons in the septum were not significantly difference among the 3 EA groups.

CONCLUSIONNOS expression in the septum increases and keeps a same level from EA for 15 min to 60 min.

OBJECTIVETo explore method of recombinant gene lentivirus containing LIM mineralization protein-1 (LMP-1) in transfecting bone marrow mesenchymal stem cells (BMSC), and to observe the effect of gene LMP-1 on proliferation effect and expression of BMSC.

METHODSSix clean SD rats aged 4 weeks were selected, bone marrow mesenchymal stem cells were extracted under sterile conditions and cultured to the third generation, then divided into three groups:control group (the third generation of BMSC), lentiviral vector transfection group (PGC-FU-GFP and Polybrene were injected into the third generation of BMSC) and recombinant gene transfection group (PGC-FU-LMP-1-GFP and Polybrene transfection were injected into the third generation of BMSC). After 48 hours' transfection, fluorescent expression were detected under immuno-fluorescence microscopy; lentiviral transfection efficiency were detected by flow cytometry; effect of lentiviral transfection on BMSC were evaluated by MTT; gene expression of transfected cells were determined by Western Blot.

RESULTS1) The third generation of BMSC was cultured successfully,and transfected with MOI:100. After 48 hours, green fluorescent expression were detected and transfection efficiency was 67% under immuno-fluorescence microscopy; 2) Compared to control group, there were no statistical differences between control group and other two groups; 3) Western blot teast showed that 72KDa specific band was observed in recombinant gene transfection group and its size was similar to LMP-1 fusion protein (50 kDa+28 kDa=78 kDa).

CONCLUSIONThere is no effect of recombinant gene lentivirus containing LIM on BMSC, and can effectively influence the expression of LMP-1.

OBJECTIVETo explore the mechanism of electroacupuncture (EA) in the treatment of post-traumatic stress disorder (PTSD).

METHODSThirty male Sprague-Dawley rats were randomly divided into a normal group, a model group and an electroacupuncture group. The single prolonged stress (SPS) method was used to set up the PTSD models in latter two groups. After SPS Stimulation, EA group was treated with 2Hz electroacupuncture at Baihui (GV 20) and Zusanli (ST 36) for 30 min, once a day for a week. Reverse transcriptase polymerase chain reaction (RT-PCR) and immuno-histochemistry were used to detect the mRNA and protein expression of nNOS in the hippocampus of rats in the each group.

RESULTS(1) The nNOS mRNA expression in hippocampus in model group was higher than that in normal group (P < 0.05). But the expression in EA group was lower significantly than that in model group (P < 0.05). (2) The nNOS protein expression in hippocampus CA1 and CA3 in model group was higher than that in normal group (P < 0.05). But after electroacupuncture treatment, its expression in EA group was lower significantly than that in model group (P < 0.05). The nNOS protein expression in hippocampal CA2 had no difference among all three groups.

CONCLUSIONThe elevated nNOS expression in hippocampus may be involved in the pathological process of PTSD. Electroacupuncture play a down-regulation effects in the hippocampal nNOS expression, which may be one mechanism of electroacupuncture for treatment of PTSD.

OBJECTIVEThough myasthenia gravis (MG) is a typical autoimmune disorder, there was some controversy on the treatment of the childhood-onset MG. By observing the efficacy of different therapies, the authors analyzed the affecting factors of prognosis in childhood-onset MG.

METHODThe retrospective data of 155 patients with childhood-onset MG (age of MG onset was less than 15 years) were collected from Department of Neurology, Beijing Tongren Hospital (January 2000 - February 2010). The patients were non-randomly divided according to their treatment into 3 groups (glucocorticoid, thymectomy and glucocorticoid combined with thymectomy groups). Postintervention status meeting the criteria of Myasthenia Gravis Foundation of America (MGFA) "complete stable remission, CSR", "pharmacologic remission, PR", "minimal manifestations, MM", or "Improved, I" was regarded as desirable response, which was used as primary indicator of observation. The authors assessed the efficacy of three therapies and analyzed the influencing factors of prognosis by using Chi-square test and Logistic regression.

RESULTAt 3 months of treatment, glucocorticoid group showed the highest effective rate. At the end of 1 year or 2 years of treatment, glucocorticoid combined with thymectomy group showed the highest effective rate respectively. The generalization rate of MG at 2 years, 10 years and 20 years in childhood-onset ocular MG patients were 4.3%, 10.7%, and 41.5%, respectively. Of patients with generalization of MG, 48.1% occurred within 2 years, 92.6% within 20 years. Univariate analysis showed that in childhood-onset ocular MG patients, variables such as age at onset (> 10 years), LG-MG and with chronic fatigue were significantly associated with general MG conversion. Whereas multivariate analysis showed that patients with age at onset (> 10 years) and chronic muscle fatigue were apt to convert to generalized MG.

CONCLUSIONGlucocorticoid appeared to have an effect that leads to early remission of symptoms in childhood-onset MG patients and glucocorticoid combined with thymectomy appeared to have better long-term effect. For those childhood-onset ocular MG patients with longer course of disease, older age of onset, chronic fatigue, or LG-MG, physicians should try to prevent the generalization of MG by immunosuppressive therapies.
