Autoimmune encephalitis is a group of inflammatory diseases related to autoantibodies that affect the central nervous system. Early diagnosis of patients with autoimmune encephalitis has certain difficulties, because the clinical manifestations caused by different types of autoantibodies can be non-specific, and the presence of multiple autoantibodies can cause variation and superposition of clinical manifestations. The article reported a case of autoimmune encephalitis patients with double positive anti-N-methyl-D-aspartate receptor and dipeptidyl-peptidase-like protein-6 antibodies, and reviewed relevant literature for clinical reference.

Objective To observe the immunologic effect of lactoferrin on repeated respiratory infection(IRRI) in children.Methods Ninety-eight cases of IRRI were divided into two groups randomly.The control group (48 cases)were treated with routine therapy.The treatment group(50 cases) were treated with lactoferrin based on routine therapy for 2-3 months.T cell subgroup,immunoglobulin and complements were determined before and after treatment.Results Total effective rates in treatment group and control group were 86% and 22.9% respectively.The therapeutic efficacy in treatment group was significantly higher than that in control group(P

Objective Through analyzing the epidemic characteristics and laws of human brucellosis in Gansu province during the past two years,to provide the basis for control of the disease. Methods Using China Information System for Diseases Control and Prevention V2.0 and survey data of human brucellosis outbreak,we calculated the incidence of brucellosis and the composition of new cases and chronic cases in 2009 and 2010, respectively, and analyzed the three distributions of the disease. Results Brucellosis incidence was 0.37 per million in 2009, and 1.7 per million in 2010. The new cases accounted for 54.6％(83/152) and 51.8％(43/83),and chronic cases were 53.3％ (81/152) and 56.6％ (47/83), respectively. About 1/3 of the counties (cities,districts) was found to be with the disease, and most cases were clustered in Hexi Corridor and Longdong area of Gansu province. There were three counties with outbreak. Time distribution of the disease was jagged. May, July,September and December were high, with September the highest. Sex ratio was 3 : 1, and mean age was 46 years old.67.7％ (159/235) of cases were farmers, followed by retired officers and herders, with a percentage of about 7％,respectively. Conclusions Epidemic of human brucellosis shows a rapidly rising trend in Gansu province. There are new patients throughout the year, and young farmers are the main victims. A high proportion of chronic brucellosis is more harmful. Strengthen the prevention and control of the disease to increase their brucellosis protective awareness.

Objective: To observe the clinical efficacy of sinew-bone balancing manipulation in treating lumbar disc herniation (LDH) and offer clinical evidence to support the concept of paying equal attention to sinew and bone. Methods: Sixty LDH patients were randomized into an observation group and a control group, with 30 cases in each group. The observation group was treated with the sinew-bone balancing manipulation, and the control group received conventional Tuina (Chinese therapeutic massage) manipulation. The clinical efficacy and posterior muscle chain tone effect were compared between the two groups by observing the visual analog scale (VAS) score, Japanese Orthopaedic Association (JOA) score, and posture-associated indicators. Results: The total effective rate was 86.7％ in the observation group, higher than 76.7％ in the control group, but the between-group difference in efficacy was statistically insignificant (P>0.05). After treatment, the VAS and JOA scores, angle-dependent muscle tone indicator of the posterior muscle chain, and lumbar posture symmetry showed significant changes in both groups (P<0.05). The VAS and JOA scores, angle-dependent muscle tone indicator of the posterior muscle chain, and lumbar posture symmetry in the observation group were significantly different from those in the control group after treatment (P<0.05), but the between-group difference in the general posture symmetry was statistically insignificant (P>0.05). Conclusion: Both the sinew-bone balancing and conventional Tuina manipulations can reduce pain in LDH patients, improve lumbar function, and adjust the angle-dependent muscle tone coefficient of the posterior muscle chain and lumbar posture symmetry; except for the general posture symmetry of the posterior muscle chain, the sinew-bone balancing manipulation wins out over the conventional Tuina manipulation.

Objective To investigate the changes in the expression of macrophage migration inhibitory factor (MIF) mRNA in a rat model of ventilator-induced lung injury.Methods Thirty adult male Sprague-Dawley rats,weighing 2β5-260 g,were randomly divided into 3 groups (n =10 each) using a random number table:control group (group C),small tidal volume (VT) mechanical ventilation group (group S) and large tidal volume mechanical ventilation group (group L).The animals were anesthetized with intraperitoneal ketamine 100 mg/kg,midazolam 0.2 mg/kg and atropine 1.0 mg/kg.The rats were tracheostomized and spontaneous breathing was maintained in group C,while the rats were tracheostomized and mechanically ventilated for 4 h in groups S and L.The tidal volume was 7 ml/kg (group S) or 40 ml/kg (group L),I ∶ E was 1 ∶ 1,RR was 80 bpm and FiO2 was 100％.At 4 h of spontaneous breathing or mechanical ventilation,broncho-alveolar lung lavage fluid (BALF) was collected for determination of the total protein concentration,white blood cell (WBC) counts and concentrations of MIF,IL-6 and IL-1β (by ELISA).Then the rats were sacrificed and the lungs removed for microscopic examination and for determination of wet to dry lung weight ratio (W/D ratio) and expression of MIF mRNA (by RT-PCR).Results Compared with C and S groups,WBC counts,concentrations of total protein,MIF,IL-6 and IL-1β in BALF,and W/D ratio and expression of MIF mRNA in lung tissues were significantly increased in group L (P ＜ 0.05).There was no significant difference in the indexes mentioned above between group C and group S (P ＞ 0.05).The pathological changes occurred in group L.Conclusion The up-regulation of MIF mRNA expression in lung tissues may be involved in the development of ventilator-induced lung injury in rats.

Objective:To evaluate the outcome and prognostic factors of conventional radiotherapy followed by intensity-modulated radiation therapy (IMRT) as a boost combined with chemotherapy in the treatment of high-grade gliomas (HGG). Methods:From Nov. 2004 to Nov. 2006, 112 HGG patients were treated with conventional radiotherapy followed by IMRT as a boost combined with chemotherapy. The radiotherapy regimen included first-course conventional radiotherapy and latE-course IMRT as a boost with the total radiation dosage of 57.5- 62.5Gy (27-29 fractions in 37-45 days). All the patients received chemotherapy. Sixty-three patients received temozolomidE-based chemotherapy and 49 patients received semustine plus teniposide chemotherapy. The treatment reaction was recorded. The overall survival rate and local progression-free survival rate were calculated. The prognostic factors were analyzed by using multivariate COX regression model. Results:The acute treatment toxicity was the most at grade 1 to grade 2 and no grade 4 adverse reaction was observed. Three cases had late radiation-induced brain necrosis. The overall 1-, 2-, and 3-year survival rates were 78.9%, 54.7%, and 30.8%, respectively. Multivariate analysis revealed that tumor location (P=0.001) and KPS score (P=0.011) were independent prognostic factors. The 1-, 2-, 3-year local progression-free survival rates were 63.8%, 38.9%, and 10.5%, respectively. Multivariate analysis revealed that tumor location (P=0.001), KPS score (P=0.001), and histologic type (P=0.005) were independent prognostic factors. Multivariate analysis did not reveal the significant correlation of temozolomide chemotherapy with the prognosis of the patients. Conclusion:Postoperative conventional radiotherapy followed by IMRT as a boost combined with chemotherapy has better short-term efficacy in the treatment of HGG and the adverse reaction is tolerable. KPS score, tumor location, and histologic type are important prognostic factors. Temozolomide chemotherapy is not associated with the prognosis of patients.

Objective To investigate the role of Toll-like receptor9 (TLR9)-myeloid differentiation factor 88 (MyD88) signal pathway in alveolar macrophages in ventilator-induced lung injury (VILI).Methods 30 adult male Sprague-Dawley (SD) rats were randomly assigned to three groups (with 10 rats in each group).Group A was the control group,with spontaneous respiration after tracheostomy.Rats in group B received mechanical ventilation for 4 hours with normal tidal volume (VT) 7 ml/kg after tracheostomy,and group C rats received mechanical ventilation with VT 40 ml/kg for 4 hours.After termination of ventilation,examination with transmission electron microscopy was performed to observe the ultrastructure changes in alveolar epithelial cell type Ⅱ (AEC Ⅱ) of the lung.Lung wet/dry ratios (W/D) and total protein concentration,the concentration of interleukins (IL-6 and IL-1 β) in bronchoalveolar lavage fluid (BALF) were determined.The protein and mRNA expressions of TLR9,MyD88 and nuclear factor-κB (NF-κB) in alveolar macrophages were assayed by Western Blot and real-time reverse transcription-polymerase chain reaction (RT-PCR).Results The ultrastructure of AEC Ⅱ in the group A and group B was almost normal,whereas the chromatin of the nuclei,the lamellar corpuscles in the cytoplasm,the cell membrane and the microvilli of the AEC Ⅱ in the group C showed injurious changes in various degrees.When the group C was compared with the group A and the group B,it was shown that the W/D ratios (5.54 ± 0.17 vs.4.58 ± 0.17,4.69 ± 0.16) and total protein concentration (g/L:6.33 ± 0.61 vs.0.45 ± 0.05,0.47 ± 0.04),IL-6 (μg/L:1.989 ± 0.103 vs.1.033 ± 0.061,1.010 ± 0.069) and IL-lβ (ng/L:2.79 ±0.25 vs.1.05 ±0.15,1.23 ±0.22) in BALF,the protein expressions of TLR9,MyD88 and NF-κB [TLR9 (A value):0.770 ±0.042 vs.0.300 ±0.027,0.310 ±0.037; MyD88 (A value):0.950 ±0.091 vs.0.560 ±0.082,0.580±0.084; NF-κB(A value):1.020 ±0.076 vs.0.740 ±0.052,0.700 ±0.076] in alveolar macrophages were all increased significantly,and all of which showed significant difference (P＜0.05 or P＜0.01).The mRNA levels of TLR9,MyD88 and NF-κB in alveolar macrophages in the group B were (1.13 ± 0.32),(1.18 ± 0.33),and (1.11 ± 0.22) folds of those of the group A,respectively,but there were no significant differences (all P＞0.05).While the mRNA levels of TLR9,MyD88 and NF-κB of alveolar macrophages in the group C were (8.66 ± 0.69),(6.41 ± 0.53) and (5.29 ± 0.71) folds of those of the group A,respectively,and all of them showed significant difference (all P＜0.01).Conclusion TLR9-MyD88 signaling in alveolar macrophages plays a role in pathogenesis of VILI.
