Methods The susceptiveness to febrile convulsion and side effects were observed in 60 Wistar rats and 90 CFC cases after administration of TPM. Results ① The latent period of febrile seizure in rats exposed to hot bath after treatment with TPM was significantly delayed ( t =3 07-3 59, P

Objective To explore the pathogenicity of Campylobacter jejuni(CJ)O∶19 strain after deletion of neuB1.Methods The mutant of CJ O∶19 by deleting neuB1,which LPS is deficient in sialic acid,was compared with the homologous wild strain by assaying their sensitivity to bactericidal activity,motility and autoagglutination of 10% normal human serum(NHS).Results The sensitivity of the mutant strain to bactericidal activity of serum was superior to that of the wild strain.The survival rate of the mutant strain was(20.6?7.4)% and(9.6?3.6)% after incubation with 10% NHS for 15 min and 60 min,that of wild strain was(36.9?5.9)% and(15.5?4.3)% respectively.The wild and mutant strains showed no significant difference in sensitivity to motility and autoagglutination of NHS.Conclusion The mutant strain possesses remarkable pathogenicity so that an inactivated vaccine from the mutant strain should be first considered.

Objective:To study the short-term effects,toxic side effects and immune function of Aidi injection adjuvant GP methods chemotherapy for advanced non-small cell lung cancer(NSCLC).Methods:130 patients with advanced NSCLC were divided into study group and the control group according to treatment methods.The study group were given Aidi injection +GP,and the control group only treated with GP.The short-term effects,toxic side effects gradeⅢ-Ⅳand immune function changes were compared between the two groups.Results:The overall response rate was 40.28%in study group,higher than 37.93% in control group(P>0.05).The two groups showed differences in the rates of leucocyte decrease,gastrointestinal reaction and platelets decrease(P<0.05).The levels of CD4,CD8 and CD4/CD8 didn′t changed obviously in study group(P>0.05),while in the control group the levels of CD4,CD8 and CD4/CD8 changed more significantly than before(P<0.05).The two groups also produced differences in CD4,CD8 and CD4/CD8 after treatment( P<0.05 ) .Conclusion: The short-term effects of Aidi injection adjuvant GP chemotherapy regimen for advanced NSCLC is similar to only GP chemotherapy,but it can obviously reduce the incidence of toxic side effects and prevent the immune func-tion.

Objective To explore the protective efficacy of antioxidants (vitamin E and Ginkgo biloba extract) on the peripheral nerve damages induced by antiepileptic drugs (AEDs). Methods Adult (2-month old) and infant SD rats (7-day old) were respectively treated with AEDs (phenytoin,or phenobarbital,or clonazepam) alone,or simultaneously with vitamin E or Ginkgo biloba extract for 4 weeks. All the rats were sacrificed,sciatic nerves and serum were collected. The sciatic nerves were analyzed by histologically for their pathological changes,and serum and homogenate of sciatic nerves were investigated for their total antioxidative capacity and antioxidant enzyme activity. Results Incidence of pathological abnormalities of teased fibers significantly reduced in all rats treated with AEDs and antioxidants (P

BACKGROUND:The main symptoms of herpes zoster (HZ) manifest as pain and skin eruption and the pain, when treated inadequately, may proceed to become post herpetic neuralgia (PHN) which has progressively increasing incidence with age.OBJECTIVE: To observe the effect of combined therapy of super laser and Durogesic patch (transdermal fentanyl) in the treatment of elderly patients with herpes zoster and diabetes.DESIGN: Randomized controlled observation.SETTING: The First Affiliated Hospital of Jinan University.PARTICIPANTS: Thirty (14 males and 16 females) elderly patients of age 62-83 years with concurrent herpes zoster (duration 6-14 days) and diabetes who had received the conventional dermatological and medication treatment but still had persistent pain were selected form the First Affiliated Hospital of Jinan University from 2003 to 2006. All elderly patients were randomly divided into 3 groups with 10 in each group.METHODS: ① Super Lizer group (SL Group): Patients were received Super Lizer (linear polarized near-infrared light) therapy once a day for 15 days. ② Durogesic patch group (DR Group): Patients were received 2.5 mg Durogesic patch once for every 3 days. ③ Combined group (SL+ DR Group): Patients were received both the Super Lizer therapy and the Durogesic patch for 15 days.MAIN OUTCOME MASURES: All patients received the assigned treatment for 3 days and VAS was evaluated before and at the 3rd, 15th day during treatment, also at 7th day after termination of treatment. Visual analogue scales were used to assess the degree of pain and global evaluation were done With pain relief more than 70% rated as excellent, pain relief between 30%-70% rated as effective and pain relief less than 30% rated as ineffective. Adverse effects were also recorded.RESULTS: Thirty patients were all involved in the final analysis. VAS scores of all three groups were significantly decreased after 15-day treatment (P ＜ 0.05); after 3-day treatment, VAS scores of DR group (2.35±1.43) and SL+DR group (2.41 ±1.54) were significantly lower than their respective baselines and that of the SL group (7.00±0.82) (P ＜ 0.05) which showed no significant change from the baseline value. SL+DR group showed significantly higher excellent rating than that of the SL group and DR group (80%, 60%, 70%, P ＜ 0.05) at the end of the 15-day treatment. At 7th days after treatment, VAS scores of SL group (3.01±1.20) and SL+DR group (2.41±1.54) were still significantly lower than that of DR group (6.70±0.67) (P ＜ 0.05) which had returned to the pretreatment level. No serious adverse effects such as respiratory depression were observed in any of the patients. Mild side effects such as dizziness, nausea and vomiting, constipation were observed in the DR and SL+DR groups which usually subsided after a week.CONCLUSION: Combined therapy of SL and DR shows a better pain relief in the elderly patients with herpes zoster and diabetes without significant adverse effects. It provides the advantage of fast onset of effect with the Durogesic patch and the long-term effect of Super Lizer.
