Objective To investigate the characteristics of extreme lateral lumbar disc herniation (ELLDH) with spiral CT multiplanar reformation (MPR), and to determine the effectiveness of MPR in the diagnosis of ELLDH. Method Twenty-five cases with ELLDH underwent conventional CT scans, thin slice spiral scan, and MPR on coronal and sagittal plane. Results Operative findings basically matched the MPR results in 25 ELLDH patients concerning the disc herniation position and compression of the nerve roots. The herniation involved the intervertebral foramina in 15 cases, external intervertebral foramina in 4, both intervertebral and external intervertebral foramina in 3, and intervertebral foramina and vertebral tubes of parity plane in 3. They were demonstrated on MPR as shapes of hillock, circular or trigonal soft-tissue density mass in intervertebral foramen, or outside and tread on the nerve root of parity plane. Among these 25 ELLDH cases, ELLDH was not found by conventional CT scans in 7 cases, but was found by MPR. ELLDH was suspected by conventional CT in 8, and was confirmed to be ELLDH by MPR. ELLDH was revealed by conventional CT scans in 10, but without indications of nerve root compression status, while MPR clearly indicated nerve root compression status. Conclusion MPR has important value in the diagnosis of ELLDH. It can properly identify the ELLDH site, shape, size, and its relation to nerve roots. It is very helpful for the surgeons in the selection of operation method.

Objective To investigate the risk factors and clinical characteristics,auxiliary examination char-acteristics,treatment and prognosis for acute stroke patients with deep vein thrombosis (DVT),in the hope of provi-ding the detailed clinical data for hospitalized patients with stroke in early prevention,early diagnosis and early treat-ment of DVT.Methods 160 cases of stroke patients were reviewed including 66 cases of patients with hemiplegia after stroke and ultrasound confirmed DVT data analysis,And compared with the same period of 94 cases of DVT in patients with stroke.The purpose of this study was to evaluate the incidence of DVT,possible risk factors,and clinical characteristics.Results Stroke in patients with DVT spent an average of 16d.DVT occurred in elderly patients (65 years or higher) with 44 cases,accounting for 66.67%;Serious paralytic 42 cases (72.72%),long-term bed 52 cases (78.78%);The most commonly comorbid disease was diabetes mellitus,hypertension and hyperlipidemia;The plasma fibrinogen concentration was (5.02 ±1.38) g/L,which was significantly higher than (2.74 ±1.65) g/L of the control group.Compared with control group,the difference was statistically significant (t=4.78,P<0.01). Conclusion Limb paralysis,long-term lie in bed,older age and high condensation state are DVT risk factors,which should be paid to prevent in advance clinically.

Objective:To investigate the content rationality of antimicrobial agent thimerosal in chloramphenicol eye drops. Meth-ods:Chloramphenicol eye drops with thimerosal at different concentrations were prepared, and the antimicrobial activity was studied. Results:When the test solution contained 0. 02 mg·ml-1 thimerosal, the antimicrobial activity could achieve the requirement in the pharmacopoeia. Conclusion:Thimerosal at different concentrations in the commercial chloramphenicol eye drops all can reach the anti-microbial effect. However, the thimerosal concentration in some eye drops is unreasonably high, which should be reduced.

Objective To investigate the efficacy of Saxagliptin on the glucose and lipids metabolism and adipokines levels in diet-induced insulin resistance rat,and to explore the regulatory mechanism of saxagliptin in insulin resistance.Methods 36 4-week-old male Wistar rats were randomly divided into two groups:control group (n=12) and high-glucose and fat diet group(HF,n =24).The HF rats were randomly divided into two subgroups:HF group and saxagliptin group,and continued the treatment for 8 weeks.Levels of blood glucose,insulin,triglyceride (TG),total cholesterol (TC),TNF-α and adiponectin were determined.Results After four months,serum levels of fasting glucose,insulin,TG,TC were significantly increased in HF group as compared with control group [(7.07±1.61) mmol/L vs.(5.10±0.44) mmol/L,(23.70±7.37) mU/L vs.(19.35 ± 6.38) mU/L],[(3.21± 1.44) mmol/L vs.(0.83 ± 0.39) mmol/L,(3.04 ± 1.62) mmol/L vs.(1.14±0.24) mmol/L,all P＜0.05],and were all decreased after the treatment of saxagliptin.The glucose infusion rate was lower in HF group than in control group and was higher in saxagliptin group than in HF group [(18.80±1.57) mg · kg-1 · min-1 vs.(24.31±2.65) mg · kg 1 · min 1,(21.45 ±1.80) mg· kg-1 · min-1 vs.(18.80±1.57) mg· kg 1 · min-1,P＜0.01 or 0.05].Compared with the control group,serum THF-α was higher and adiponectin level was lower in HF group [(1.38 ±0.18) μg/L vs.(2.33±0.21)μg/L,(2.65±0.29) mg/L vs.(1.38±0.20)mg/L,both P＜0.01].Saxagliptin can significantly increase the serum level of adiponectin and decrease the level of TNF-α in HF group (P＜0.01 or 0.05).Conclusions Saxagliptin treatment can improve high-fat dietinduced insulin resistance,decrease blood lipids levels and regulate the levels of adipokines in HF rats.
