Objective To analyze the correlation between serum antinucleosome antibody (AnuA) and renal pathological characteristic,disease activity as well as some laboratory tests in patients with lupus nephritis (LN).Methods Serum AnuA levels were detected by enzyme-linked immunosorbant assay in 40 patients with LN (observation group) and 40 healthy people (control group).Renal biopsy was examined in all LN patients.The relationships between serum AnuA level and systemic lupus erythematosus disease activity index (SLEDAI),renal pathohistology,laboratory parameters were analyzed.Results The serum AnuA level in observation group before treatment was significantly higher than that in control group [ ( 110.23 ± 80.48) kU/L vs. ( 10.45 ± 8.20) kU/L,P ＜ 0.05 ].Four cases of renal biopsies were class Ⅱ,8 cases were class m,23 cases were class Ⅳ,and 5 cases were class V.Serum AnuA level had significant difference between each class by Kruskal-Wallis rank sum test (P ＜ 0.05),and serum AnuA level of class Ⅳ was the highest (P ＜ 0.05).Serum AnuA level had positive correlation with SLEDAI,urine protein quantitation and anti-double strands DNA antibody (r =0.462,0.521,0.394,P ＜0.05),negative correlation with complement C3 and C4 levels (r =-0.403,-0.489,P ＜ 0.05 ).Serum AnuA level after treatment [ (32.45 ± 18.31) kU/L] was significantly decreased than that before treatment [(110.23 ± 80.48) kU/L](P＜0.05).Conclusions Serum AnuA level is not only a good index of LN activity,but also reflect renal involvement.That serial measurement of serum AnuA level may provide better clinical strategies for the therapy.

Objective To investigate the curative effect of methotrexate in treating systemic lupus erythema-tosus(SLE). Methods The chosen outpatients were divided into 2 groups,group A(28 cases) :MTX combined with small dosage of prednisone (prednlsone 10mg/d) ; group B (20 cuses) : medium dosage of prednisone (prednisone 30rag/d). Observation includes SLE disease activity index(SLEDAI) ,relapse while dosage of prednisone was reduced to small amount and drug side effects. Results The SLEDAI score of group A was reduced from (9.4±2.1) to (4.1±0.9) ,and group B from (8.6±2.5) to (4.0±1.0). Compared the result of before and after treatment be-twcen the two groups, the curative effect is obvious (P<0.01). However, there was no significant difference of efficacy between the two groups(P>0.25). While dosage of prednisone was reduced to 10mg/d ,there were 8 cases of relapse in group B,and only 3 cases in group A during the entire observation period. The difference is significant (P<0.025). The side effect of group A is gastrointestinal reaction and for B is mainly the cushing syndrome. Conclusion MTX is an effective treatment fw the light and medium activity SLE,and can reduce the dose of prednisone, prevent long-term using large dose of prednisone which will cause side effect.

The effects of sulfated polysaccharides from brown seaweeds GS201 on neuronal survival of cultured brain neurons were investigated in this paper.Results indicated that GS201 at concentrations of 0.01 0.1 1 10 mg?L -1 significantly enhanced the neuronal survival of both hippocampus and neurocortex.The mechanisms underlying the neurotrophic effect exerted by GS201 need to be further elucidated.

The antinociceptive effect of epidural administration of huwentoxin-I was elucidated in a tonic visceral pain rat model produced by acute colon inflammation. The nociceptive behaviors were induced by perendoscopically injecting dilute formalin (50 μl) into the depth of the colonic wall in rats. Both ω-conotoxinMVIIA and morphine hydrochloride were given epidurally as positive control while saline as negative control.Similar to ω-conotoxin-MVIIA and hydrochloride morphine, the epidural administration of HWTX-Ⅰ significantly reduced the nociceptive responses in a dose-dependent manner in tonic visceral pain rat model ( P ＜ 0.05). The suppression effects of both huwentoxin- Ⅰ and ω-conotoxin-MVIIA at 20 μg/kg were kept steady compared with the saline group and reached their maximum effects at the doses of 50 ～ 75 μg/kg within 1 hour when the nociception had been observed. It was also found that at the same doses, huwentoxin- Ⅰ was less effective in antinociception than ω-conotoxin-MVIIA. However, ω-conotoxin-MVIIA, but not huwentoxinⅠ , caused an obvious motor dysfunction at these doses. The action of morphine hydrochloride was initiated faster, but lasted for a shorter time than that of huwentoxin- Ⅰ and ω-conotoxin-MVIIA. Thus, huwentoxinⅠ , a potent blocker of neuronal N-type voltage-sensitive calcium channels, induced a remarkable dosedependent restrain effect similar to ω-conotoxin-MVIIA and morphine on the tonic visceral pain produced by colonic wall injection of formalin in conscious rats.

AIM: To study the protective effect of ethyl pyruvate(EP) on hepatocytes in septic mice.METHODS: The cecal ligation-perforation was made in mice as septic model.Ringer's ethyl pyruvate solution(REPS) and Ringer's lactic solution(RLS) were used to resuscitate septic mice.Anti-oxidative capacity of hepatic tissue and liver function were detected in different groups.RESULTS: Anti-oxidative capacity in septic mice was significantly lower than that in sham group(P

Objective To study the tolerance to 188Re-1-hydroxy-1 ,1-ethylidene disodium phosphonate(HEDP) in patients with bone pain caused by osseous metastases. Methods Thirty-one patients(10with prostate cancer, 9 with breast cancer, 3 with lung cancer, 5 with liver cancer, 2 with rectal cancer, 1with esophageal cancer and 1 with renal cancer) received a single injection dose of 188Re-HEDP. The patients were divided into four groups according to the injection dose: 20 MBq/kg (6 patients), 30 MBq/kg(6 patients), 40 MBq/kg (9 patients), and 50 MBq/kg (10 patients). Haematological toxicity (WHO grading) of grade Ⅲ- Ⅳ was considered unacceptable. Vital signs and adverse effects after injection were recorded for 8 weeks. Blood counts were measured weekly during a period of 8 weeks. Biochemical parameters and electrocardiogram were assayed at week 4 and 8. Statistical analysis was performed for per-protocol (pp) population (t-test). Results Twenty-seven patients belonged to PP population with 5 in the group of 20 MBq/kg, 5 in the group of 30 MBq/kg, 8 in the group of 40 MBq/kg and 9 in the group of 50 MBq/kg.No obvious adverse effects and no significant change of vital signs, electrocardiogram, liver and renal function were found after injection. Alkaline phosphatase was slightly higher than baseline at week 4 and 8 after therapy, but the difference was not statistically significant. In the 20 MBq/kg group, reversible grade Ⅰ leucopenia was noted in 1 patient. In the 30 MBq/kg group, 2 patients showed reversible grade Ⅰ leucopenia including 1 alone with reversible grade Ⅲ thrombopenia. In the 40 MBq/kg group, reversible grade Ⅰ leucopenia and thrombopenia was observed in 1 patient and reversible grade Ⅱ leucopenia and thrombopenia in another patient. In the .50 MBq/kg group, 3 patients showed reversible grade Ⅱ leucopenia. The lowest level of thrombopenia was at week 4(143.5 × 109/L), leucopenia at week 6 (5.4 × 109/L) and anaemia at week 8(t = 3.1325, 3.3156, 3.4917, all P ＜ 0. 05 compared with baseline). At week 8, the mean level of platelet and leucocyte recovered to baseline. "Bounce pain" was found in 2 of 27 patients (7.41%).Conclusions The dose of 20 MBq/kg, 30 MBq/kg, 40 MBq/kg or 50 MBq/kg of 188Re-HEDP do not cause significant side effects on cancer patients with bone metastases, though there is a tendency that the haematological toxicity may increase as the dose of 188Re-HEDP increases.

OBJECTIVE: To repair the postoperative tissue detect of the base of tongue cancer in advanced patients. METHOD: There were 30 patients of medium-high differentiation squamous cell carcinoma(SCC) included in this study. According to the TNM staging of AJCC 2002, there were 4 cases of T2N1M0, 7 of T3N1M0, 10 of T3N2M0, 4 of T4N1M0 and 5 of T4N2M0. Surgical approach of the primary lesion: 12 with transhyoidpharyngotomy approach and 18 with mandibulotomy approach. All cases accepted radiotherapy 4-6 weeks after surgery. RESULT: Twenty-five cases were reconstructed with pedicle pectoralis major myocutaneous flaps, and all them survived. Among them, 1 flap was partial split with surrounding tissue spontaneously, and another flap had partial tissue necrosis, however, both flaps grew well with dressing and other local treatment. Other 5 cases were reconstructed with free anterolateral myocutaneous flaps. Among them, 1 flap had partial tissue necrosis, but had a secondary healing after removing necrotic tissue via mouth approach. All 18 patients of larynx-preservation had tracheal tube pulled out. The 3-year survival rate was 68% and the local control rate was 87%. CONCLUSION Pedicle pectoralis major myocutaneous flaps and free anterolateral myocutaneous flaps were alternative donor area for repairing postoperative tissue defect of the base of tongue; The former was preferred, and the latter was concealed so as to be a kind of effective method, which need adept technique of microsurgery.
