OBJECTIVE To investigate the effect of pranlukast(Pran) on learning and memory impairment and neuroinflammatory and apoptotic response in streptozocin(STZ)-induced type 1 diabetic mice. METHODS Male ICR mice were injected through the tail vein with STZ(150 mg·kg-1)to induce the type 1 diabetes model. Diabetic mice were administered orally with Pran. After 4 consecutive weeks of administration,the escape latency in hidden platform trials,number of platform crossings and time spent in the target quadrant of mice were assessed by the Morris water maze(MWM)test. Western blot was used to detect the proteins of cysteinyl-leukotrienes receptor-1(CysLT1R)and pro-inflammatory factors,nuclear factor-κB p65 subunit(NF-κB p65),interleukin-1β(IL-1β),tumor necrosis factor-α(TNF-α),and cleaved caspase 3,Bax and Bcl-2 in the hippocampus and prefrontal cortex of diabetic mice. We also determined fasting blood glucose,serum insulin and lipids such as triglyceride,total cholesterol,high density lipoprotein cholesterol,and low density lipoprotein cholesterol. RESULTS The data of the MWM test showed that untreated diabetic mice displayed a higher escape latency in hidden platform trials(P<0.05),and a smaller number of platform crossings(P<0.05)as well as shorter per?centage of time spent in the target quadrant(P<0.05). The data of Western blotting showed that treat?ment with Pran 0.6 and 1.2 mg·kg-1 significantly reduced the levels of CysLT1R,nuclear NF-κB p65, IL-1βand TNF-α,cleaved caspase 3,and the ratio of Bax and Bcl-2 in the hippocampus and prefrontal cortex of diabetic mice(P<0.05). However,Pran did not improve the fasting blood glucose,serum insulin or lipid metabolism disorder in diabetic mice. CONCLUSION Pran improves memory impairment and nerve injury in STZ-induced type 1 diabetic mice.

Celiac disease (CD) is a chronic autoimmune gastrointestinal disorder induced by ingestion of gluten-containing foods.In the past CD was thought prevalent only in Western countries,whereas it has been found common throughout the world and increasing numbers of Chinese patients has been reported recently.However,there are still many deficiencies in management of patients with CD in China and either the diagnosis or the treatment of CD is lacking evidence-based clinical pathway.We report a case of a young woman with CD presenting with chronic diarrhea,abdominal distention,and weight loss,whose outcome was improved by following evidence-based guidelines of medical nutrition therapy.Diagnosis and treatment of the patient was analyzed with review of foreign and domestic literature to provide readers reference of the standardized nutritional intervention of CD.

Objective To observe the effects of early rehabilitation training on serum brain-derived neurotrophic factor (BDNF) expressionand motor function in patients with acute cerebral infarction. Methods 48 patients with acute cerebral infarction were randomly dividedinto rehabilitation group (n=24) and control group (n=24). The control group accepted routine medication, while the rehabilitation group acceptedearly rehabilitation training in addition. They were assessed with Fugl-Meyer Assessment (FMA), and the expression of BDNF in serumwas detected before and after treatment. Results The expression of BDNF and the score of FMA increased significantly after treatmentin both groups (P<0.05), but increased more in the rehabilitation group than in the control group (P<0.05). Conclusion Early rehabilitationtraining can promote the expression of serum BDNF and recovery of motor function in patients with acute cerebral infarction.

Objective To understand the status of Toxoplasma gondii(TOX)infection in pregnant women in Qingdao area. Methods Antibody capture ELISA was used to detect the TOX-IgM,IgG and TOX-DNA in 1 341 pregnant women and 201 infer-tility,miscarriage,stillbirth pregnant women from June 2011 to July 2013. Results Among 201 abnormal pregnant women,43 cases were TOX antibody positive,accounting for 22.39%,and among the normal pregnant women,84 cases were TOX antibody positive,accounting for 6.26%,and there was a significant difference(χ2 =10.60,P<0.05). The TOX positive rate of 20-29 years old women was higher than that of the women aged over 30 years(χ2=21.9,P<0.05). The TOX antibody positive rates of families with pets and families without pets were 26.63%and 8.77%respectively(χ2=10.93,P<0.05). The TOX antibody posi-tive rates were 10.94%(22/201)in unemployed women,3.98%(8/201)in farmers,3.98%(8/201)in staff,and 3.48%(7/201)in workers. Conclusions The TOX infection rate in abnormal pregnant women is significantly higher than that in normal pregnancy women;therefore,the health education should be strengthened. In addition,in young women,especially 20-29 years old women, and some special occupation women,the control measures should be enhanced.

In order to study the effects of Ca2+ in the biosynthesis of salvianolic acid B (Sal B) induced by salicylic acid (SA) in the young seedlings of Salvia miltiorrhiza, we used confocal laser scanning microscopy and high performance liquid chromatography to measure the change of relative fluorescence intensity of Ca2+ and the contents of Sal B induced by SA before and after the application of extracellular calcium channel inhibitors (VP and LaCl3), intracellular calcium channel inhibitor (LiCl), as well as intracellular calmodulin antagonist (TFP). SA could induce the calcium burst, and the Ca2+ peak could last to 2-3 min in the guard cells of S. miltiorrhiza, which prompted the biosynthesis of Sal B after the Ca2+ burst. Both Vp or LaCl3, and LiCl or TFP could inhibit the burst of Ca2+ and the biosynthesis of Sal B. The above results demonstrated that Ca2+ from the extracellular and the intracellular calcium store regulate the biosynthesis of Sal B elicited by salicylic acid in S. miltiorrhiz young seedlings.

This study was aimed to establish a method for the rapid content determination of Ixerin Z and 11,13α-dihydroixerin Z in Ku-Die-Zi (KDZ) injection by UPLC-ESI-MS/MS. The separation was performed on a Waters ACQUITY BEH C18 column (2.1 mm × 50 mm, 1.7μm) by using a gradient elution with the mobile phase of acetonitrile-water at the flow rate of 0.4 mL·min-1. The column temperature was set at 40℃. Multi-reaction moni-toring (MRM) scanning was employed for quantification in ESI negative mode. The results showed that two sesquit-erpene lactones in KDZ injection were totally separated within 2 min. The linear range of Ixerin Z was 5.70-182.50 ng·mL-1, and the linear range of 11,13α-dihydroixerin Z was 4.60-131.25 ng·mL-1. The correlation coefficient r was more than 0.999 0. The recovery rates (n = 6) were 98.18% and 97.52%, with RSDs < 1.5%. The established method was successfully applied for simultaneous content determination of Ixerin Z and 11,13α-dihydroixerin Z in 6 batches of KDZ injection from 2 factories, which had some variations on the content determination results. It was concluded that the method was rapid, accurate and sensitive, which can be used for the content determination of two sesquiterpene lactones in KDZ injection.

BACKGROUND:In recent years,artificial cervical disc replacement surgery as a new method for the treatment of cervical disease has gradualy been accepted and understood,but relevant complications have gradualy attracted attention.OBJECTIVE:To investigate the clinical outcomes of artificial cervical disc replacement in the treatment of cervical disease and the range of motion of the replacement segment.METHODS: A total of 25 patients with artificial cervical disc replacement in the treatment of cervical spondylosis,who were treated in the Department of Orthopedics,Air Force General Hospital of Chinese PLA from August 2006 to April 2012,were enroled in this study,including 15 males and 10 females,aged 31-76 years,averagely 51.04 years.There were 6 cases of double segments and 19 cases of single segment.They were folowed up for 24 to 93 months.Clinical results were assessed using the Japanese Orthopaedic Association score,cervical dysfunction index and pain visual analog scale scores.Imaging was used to observe range of motion,cervical curvature,heterotopic ossification,and degeneration of adjacent segments.RESULTS AND CONCLUSION:Neurological function in al patients was improved to different degrees.One case suffered from mild heterotopic ossification,but no clinical symptoms were found.No significant difference in range of motion of surgical segment,and range of motion of upper and lower adjacent segments was detected between pre-replacement and final folow-up results (P＞0.05).No significant difference in range of motion of C2-C7 was found between pre-replacement and final folow-up results (P＞0.05).Japanese Orthopaedic Association score,cervical dysfunction index and pain visual analog scale scores were significantly improved during final folow-up compared with pre-replacement (P＜0.05).These results indicated that artificial cervical disc replacement in the treatment of cervical disease can achieve better clinical efficacy,can keep the range of motion of replacement segment and avoid the accelerated degeneration of adjacent segments.
