OBJECTIVE: To evaluate the short-term efficacy and investigate the factors of specific immunotherapy (SIT) efficacy of allergic rhinitis. METHOD: Fifty-seven patients with allergic rhinitis to dermatophagoides pteronysinus were included to receive SIT. Pair t-test was used to compare the symptom scores, visual analogue scores (VAS) and medication scores in patients before SIT and into maintain treatment statement to evaluate the clinical efficacy. T-test and Spearman correlation analysis were used to analyze the correlation between gender, age,reaction condition of skin prick test (SPT) and serum sIgE and the efficacy of SIT. RESULT: SIT was able to significantly reduce the symptom scores, VAS and medication scores. But the correlation between gender, age, SPT, and sIgE and theefficacy of SIT were not significant. CONCLUSION SIT is effective in the short-term treatment of AR. Further research is needed to investigate the factors that impact the efficacy of SIT.

OBJECTIVE: To investigate the relation between IL-4/STAT6 and allergic rhinitis by comparing expressions of IL-4 and STAT6 in normal nasal mucosa and allergic rhinitis models, to explore the influence of glucocorticoid on IL-4, and STAT6 expression, and then to elucidate further the pathogenesis of AR and the mechanism of glucocorticoid. METHOD: Forty-five guinea pigs were divided into three groups: normal control (NC) group, allergic rhinitis group (AR) and glucocorticoid (Glu) group (15 each). Animals in AR and Glu groups were sensitized with egg albumin, and in NC group were treated with normal saline as control. After sensitization and reproduction of AR model, rats in AR group received no treatment, while those in Glu group were treated with glucocorticoid (50 microl/one side/time, once a day) for 5 days. The changes in behavior was examined, and pathology of nasal mucosa were observed with HE staining, and the protein expressions of IL-4 and STAT6 in the nasal mucosa were detected by immunohistochemical technique. RESULT: Compared with NC group, the frequency of sneezing and nose-scratching, and the expressions of IL-4 and STAT6 were increased obviously, but the opposite findings were observed in Glu group. CONCLUSION IL-4 and STAT6 are related to the pathogenesis of allergic rhinitis and may be the main factors for eosinophil infiltration in allergic rhinitis. Glucocorticoid may produce a therapeutic effect by intervening the expression of IL-4 and STAT6.

OBJECTIVE: To detect the expression and distribution of the lung surfactant protein D (surfactant protein D,SP-D ) and IL-16 in nasal mucosa of allergic rhinitis and nasal polyps, and then probe into their significance in the pathology of allergic rhinitis and nasal polyps. METHOD: Fifteen cases of allergic rhinitis, fifteen cases of nasal polyps and fifteen cases of inferior turbinate mucosa were studied to detect the expression of SP-D and IL-16 by immunohistochemistry method. RESULT: The expression of SP-D and IL-16 in allergic rhinitis and nasal polyps were dramatically higher in controls (P < 0.01). There was no remarkable difference in the expression of SP-D and IL-16 between allergic rhinitis and nasal polyps (P > 0.05). CONCLUSION Both normal tissue and diseased tissue express SP-D and IL-16. SP-D is likely to play key roles in the inflammatory reaction process of allergic rhinitis and nasal polyps. IL-16 is an important eosinophil chemokine in the process of allergic rhinitis and nasal polyps,and it can also enhance the local role of eosinophils,thus it can involve in the process of allergic rhinitis and nasal polyps disease.

OBJECTIVE: To compare the efficacy of Epley's manoeuvre and Epley's manoeuvre plus labyrinthine sedative in the treatment of benign paroxysmal positional vertigo. METHOD: Eighty-four patients with benign paroxysmal positional vertigo were included in a randomized study. Forty-two cases in control group were treated with Epley's manoeuvre alone and the other 42 cases in treated group received Epley's manoeuvre together with Betahistine mesilate tablets, flunarizine hydrochloride, and extract of Ginkgo biloba leaves tablets. Both groups were analyzed after one week and four weeks, and recurrence was observed after half a year. RESULT: After one week treatment, cure rate and total effective rate of treated group was higher than that of control group (78.57% vs. 50.00% and 92.86% vs. 80.95%, P < 0.05, respectively). After four weeks treatment, there was no significant difference in cure rate and total effective rate between two groups (80.95% vs. 71.43% and 95.24% vs. 90.48%, P > 0.05, respectively). After half year, recurrence was found in 3 patients in treated group compared with 7 patients in control group (7.14% vs. 16.67%), and the difference was statistically significant (P < 0.05). CONCLUSION Epley's manoeuvre is the best treatment method of benign paroxysmal positional vertigo together with the medicine. It is easy, safe and effective, and the healing time can be shortened.

ObjectiveTo explore the mechanism of extracorporeal shock wave (ESW) in treating osteogenic disorders and the ideal energy level. MethodsAfter success in marrow aspiration from patients' iliac crest, hMSCs were isolated by Percoll density gradient centrifugation and cultured in Dulbecco's modified Eagle's medium in a 5% CO2 and 37 ℃ incubator. Optimal ESW dose was determined by MTT of kinase-marked cytobiology. After hMSCs were exposed to ESW, their morphocytologic change, rate of adherence and doubling time were observed with IPCM. Enzyme cytochemistry reaction for the activity of alkaline phosphatase was also examined. ResultsESW of 5 kV and 100 times could increase cells' viability and proliferation (P<0.01), but higher than 7 kV would inhibit them. Rate of adherence of hMSCs in exposure group of passage 5 reached to 61.54%, which was significantly different from control group(P<0.05). Compared with control group, the MSCs' doubling time was short for 1.72 d (P<0.05). The curve of normal alkaline phosphatase activity of hMSCs was like type S, but ESW shortened its latent period, and promoted its peak time, which was significantly different from control group.ConclusionESW of 5 kV and 100 times can optimally promote the proliferation and activity of osteogen of hMSCs in vitro.

OBJECTIVETo study the influence of separation of distal tibiofibular syndesmosis on ankle joint and to compare various operative methods so as to find suitable stabilization for separated distal tibiofibular syndesmosis.

METHODSFrom July 1997 to July 2002, we treated 87 patients (64 males and 23 females, aged 18-54 years) with separation of distal tibiofibular syndesmosis, among whom, 79 were combined with fracture of malleolus. Manipulative reduction, internal fixation with cancellous screws and external fixation with plaster support were performed on 37 patients, fixation with plate and screws for fibular fracture and fixation with cancellous screws for distal tibiofibular syndesmosis on 34 patients, and repair of the distal tibiofibular ligaments with tendon of peroneus longus, reduction of the separated distal tibiofibular syndesmosis, and fixation with cancellous screws on 16 patients. The ankle joint had been dorsiflexed for 30 degrees when the distal tibiofibular syndesmosis was fixed with cancellous screws. And the cancellous screws were taken out at 8-10 weeks after operation.

RESULTSThese patients were followed up for at least two years. The curative effects were assessed according to the complaints of the patients and the contour, function and radiogram of the ankle joint: excellent in 55 patients (63%), good in 18 patients (21%), and fair in 14 patients (16%). Separation of distal tibiofibular syndesmosis recurred in 2 patients, who underwent a reoperation for repairing the distal tibiofibular ligaments with tendon of peroneus longus and recovered. One cancellous screw was broken off. No necrosis developed in the anterior skin of the ankle mortise.

CONCLUSIONSSeparation of distal tibiofibular syndesmosis can be treated with various reasonable operations. Repair with tendon of the peroneus longus can get excellent outcomes for complete separation of the distal tibiofibular syndesmosis.

BACKGROUND/AIMS: Although lipoprotein lipase (LPL) gene Pvu II polymorphism has been associated with an increased risk of hypertriglyceridemia (HT), there is no clear consensus within the scientific community. METHODS: A meta-analysis of 1,640 subjects from six individual studies was conducted to better elucidate the potential relationship between the LPL gene Pvu II polymorphism and HT within the Chinese population. Pooled odds ratios (ORs) and their corresponding 95% confidence intervals (CIs) were evaluated by using fixed effect models. RESULTS: Our analysis indicated a significant association between LPL gene Pvu II polymorphism and HT within the Chinese population under allelic (OR, 1.550; 95% CI, 1.320 to 1.830; p = 1.158 × 10-7), recessive (OR, 0.540; 95% CI, 0.390 to 0.750; p = 0.0002), dominant (OR, 1.889; 95% CI, 1.501 to 2.377; p = 5.960 × 10-8), homozygous (OR, 2.167; 95% CI, 1.531 to 3.067; p = 1.242 × 10-5), heterozygous (OR, 1.810; 95% CI, 1.419 to 2.309; p = 1.842 × 10-6), and additive genetic models (OR, 1.553; 95% CI, 1.320 to 1.828; p = 1.158 × 10-7). CONCLUSIONS: Because LPL gene Pvu II restriction fragment length polymorphism polymorphism was associated with an elevated risk of HT, the P+ allele carriers of the LPL gene might be predisposed to HT.
