Therapies for malignant glioma include surgery,radiotherapy and chemotherapy.In recent years,the overall effective rate of temozolomide is better than other chemotherapy drugs,but partly patients have resistance to temozolomide.Angiogenesis inhibitors show promising activity,but it is expensive.Celecoxib has antiangiogenic activity,which has become a new option.

Five known compounds have been isolated from the culture of an endophytic fungus Fusarium sp., which was originated in a seagrass Spartina alterniflora. Their structures have elucidated by TLC comparision with standard and spectral methods as ergosterol (Ⅰ), ergosterol peroxide (Ⅱ) cinnamic acid (Ⅲ), para-hydroxyphenylpropionic acid (Ⅳ) and beauvericin (Ⅴ), respectively.

Objective To study the effect of Rho-kinase inhibitor on experimental allergic neuritis. Methods 54 female Lewis rats were divided into three groups; EAN group, EAN + Rho-kinase inhibitor group, and CFA group. The rats were sacrificed on the 9th day, 17th day, and 26th day after immunized. The changes of weight, EAN incidence, and mean day of onset, mean maximum clinical score, and histopa-thology were observed. Results The clinical course in EAN group reached peak on the 17th day. Compared with EAN group, the weights of Rho - kinase inhibitor group were increased, while EAN incidence, mean day of onset delay, and the clinical scores in Rho-kinase inhibitor group were significantly decreased, ( P < 0.01) , and the demyelization and inflammation cells infiltrating was ameliorated in spinal nerve. CFA group didnt show any clinical manifestation. Conclusions Rho - kinase inhibitor may ameliorate the development of EAN through inhabiting the Rho/ROK signal pathway.

This is a report of 3 cases of parkinsonism with long term administration of lamivudine. The clinic
features were mask like faces, shuffling gait, lethargy and reduced automatic movement. After stopping
use of lamivudine and treatment of anticholingeric drugs, the symptoms and signs of all cases were
ameliorated. The possibilities of Wilson’s disease and other secondary parkinsonisms were excluded.
The parkinsonism was attributed to complications from lamivudine. Lamivudine associated parkinsonism
has not been reported previously in the medical literature.

Objective To analyze the factors related to the occurrence of complications in performing CT-guided percutaneous lung biopsy with 18 G-Bard Magnum needle. Methods CT-guided percutaneous lung biopsy with 18 G-Bard Magnum needle was carried out in a total of 58 patients. The postoperative complications were recorded, and the related factors causing complication were analyzed. Results Successful puncturing was achieved in all patients with a technical success rate of 100%. Postoperative complications included pulmonary hemorrhage (n=11,19.0%), a little amount of bleeding in needle tract (n=7,12.1%), hemoptysis (n=3,5.2%), hemothorax (n=1,1.7%), and pneumothorax (n=10,17.2%). Chi-square test showed that the occurrence of pulmonary hemorrhage bore a close relationship to the lesion’s diameter, the distance between the lesion and the chest wall, the lesion’s location and times of puncturing (P<0.05). The occurrence of pneumothorax was closely correlated with the age, the distance between the lesion and the chest wall, the presence of perifocal emphysema, the lesion’s location and times of puncturing (P<0.05). Univariate analysis indicated that the postoperative complications were liable to occur in the patients whose imaging examination showed perifocal emphysema and lung hilar lesion, and who had more than two independent risk factors (P<0.05). Conclusion CT-guided percutaneous lung biopsy with 18 G-Bard Magnum needle is an accurate and safe technique with relatively higher positive diagnosis rate, but this technique should be carefully used in patients who has perifocal emphysema, or lung hilar lesion, or more than two independent risk factors.(J Intervent Radiol, 2015, 24:792-796)

Objective To study the clinical and pathological features in the elderly patients with chronic inflammatory demyelinating polyneuropathy (CIDP). Methods The features of the clinical manifestation, cerebrospinal fluid, electromyogram(EMG) and the biopsy results of sural nerve were presented and analyzed in 11 elderly patients with CIDP. Results Two cases had history of upper respiratory tract infection before the onset. As the initial symptoms , there were three cases with distal limb numbness, five cases with both distal lower extremities numbness, two cases with both distal upper extremities numbness and one case with difficulties to raise his head. Motor disorder was common to all the patients. There were eight patients with sensory dysfunction, three with limb muscle atrophy, one with muscle tenderness, eight with tendon reflexes weakened or disappeared, five with cranial nerve damaged, three with the autonomic nerve lesion, one with respiratory muscle involved, three with relapse. The score of the peak incidence as Modified Rankin was 3.02 points on average. Five cases had obvious albuminocytolgoic dissociation by the examination of cerebrospinal fluid, ten cases had neurogenic damage and one case had a combined myogenic and neurogenic damage by the EMG. The biopsy showed that six cases were with amyelination,six cases with inflammatory cell infiltrated, two cases with obvious remyelination, two cases with auxiliary fibers degeneration.And the methylprednisolone therapy was effective for eight cases. Conclusions The numbness of the distal limb is the initial symptom of the elderly patients with CIDP,most of whom are with sensory dysfunction ,and some with cranial nerves and autonomic nerve damage. The sural nerve biopsy has an important value for the diagnosis of the elderly with CIDP. The methylprednisolone therapy is proved to be effective for most patients.

Objective To explore the effect of Gliclazide Sustained-release Tablets on the glucose and PAI-1 of patients with new-onset type 2 diabetes mellitus (NOT2DM).Methods Ninety patients with NOT2DM were randomly divided into two groups.Based on the treatment of proper exercise and dietary control,the control group orally took Metformin Tablets,while the treatment group took Gliclazide Sustained-release Tablets combined with Metformin Tablets.Both courses of treatment were 12 weeks.The changes of glucose and blood lipid-related indexes as well as adverse reactions were observed in both groups.Results After treatment,the levels of fasting plasma glucose (FPG),2 h postprandial glucose (2hPG)and glycosylated hemoglobin (HbA1c)in two groups went down obviously by comparison to treatment before,in which the decreased degrees in treatment group were more significant,with statistical significance.There was no statistical significance be-tween two groups regarding the levels of blood lipids before and after treatment,but PAI-1 level in treat-ment group after treatment was markedly lower than in control group.Conclusion For the patients with NOT2DM,Gliclazide Sustained-release Tablets combined with Metformin Tablets can significantly enhance the effect of decreasing glucose and lower PAI-1 level,with the efficacy superior to Metformin Tablets alone.

OBJECTIVE:
To examine the expression of mRNA of Oxford 40(OX40) and Oxford 40 ligand(OX40L) in the sciatic nerve, spleen, peripheral blood mononuclear cells and lymph nodes of experimental allegic neuritis (EAN).
METHODS:
Thirty-six Lewis rats were randomly assigned into an EAN group and a CFA group. The rats were sacrificed on 9th, 17th, and 26th day after immunization. OX40 and OX40L mRNA was detected by reverse transcription polymerase chain reaction in the spleen, sciatic nerves, peripheral blood mononuclear cells and lymphonodes.
RESULTS:
The peak of clinical course came on 17th day after the immunization in EAN. The mRNA expression of OX40/OX40L was higher on 8th day and 17th day than that on 26th day after the immunization (P<0.05). There was significant difference between the EAN group and the CFA group at the 3 time points (P<0.05); rats in the CFA group didn't have any clinical manifestations. The mRNA expression of OX40 and OX40L in the EAN group raised in the sciatic nerves and lymph nodes at the above 3 time points (P<0.05). Weak expression was seen in the peripheral blood mononuclear cells.
CONCLUSION
OX40 and OX40L may play a role in the pathogenesis of experimental allegic neuritis.
