The serum suppressive activity on PHA-induced lymphocyte transformation of healthy individuals was evaluated in 76 serum samples from 55 patients with systemic lupus erythematousus(SLE).The serum suppressive activity seemed well correlated with the activity of SLE. The highest levels of suppressive rate (55.02+29.62％) and positive rate(88.33％)were found in patients with active disease. Once disease improved, both suppressive rate and positive rate were reduced (22.17?51.28％ and 51.85％ respectively), when the patients entered into stationary stage, the serum suppressive activity were not observed. The correlation between suppressive activity and lymphocyte transformation test, E-rosett inhibition factor, the levels of serum CIC, IgG, IgA, IgM. C3 and ANA titers were analysed. Stepwise discriminant analysis indicated that the serum suppressive activity was more closely related to disease activity than other immunological indexes. The nature of suppressive factor was discussed.

Objective To observe the effect of wheel running exercise on subventricular zone neurogenesis and the neural function in rats post cerebral ischemia. Methods 48 adult male Sprague-Dawley rats were induced cortical infarcts with left middle artery occlusion and were housed in either standard (control group, n=24) or wheel running (exercise group, n=24). They were assessed with neurological severi-ty scores (NSS), and the expression of Ki67 was determined with immunofluorescence, 3, 7, 14 and 21 days after training. Results Com-pared with the control group, the number of Ki67-labeled cells in subventricular significantly increased in the exercise group 14 and 21 days after ischemia (P<0.05), and the NSS decreased since 7 days after ischemia (P<0.05). Conclusion Wheel running may promote the neuro-genesis in subventricular of adult rats after cerebral infarction, which may associate with the recovery of neural function.

Objective: To compare the ocular parameters of acute angle closure glaucoma (AACG) and chronic angle closure glaucoma (CACG). Methods: Totally 106 patients with primary angle closure glaucoma were recruited: 58 patients with AACG and 48 with CACG. All patients were divided into 3 groups: AACG attack eyes group, AACG uninvolved fellow eyes group and CACG group and underwent the same ophthalmic examinations, comprising optometry, keratometry, and A-scan ultrasonography. The lens/axial length factor (LAF) and relative lens position (RLP) were calculated. Results: The AACG attack eyes had a significant shallow anterior chamber depth, thick lens, short axial length and larger LAF. hTere tended to be a reduction in the percentage of LAF>0.20 in AACG attack eyes, CACG eyes and AACG uninvolved fellow eyes, though there were no statistically signiifcant difference in all groups (P>0.05). Conclusion: The eyes with AACG attack have a more crowded anterior chamber structure compared with uninvolved fellow eyes and eyes with CACG.

Background and purpose:Concurrent chemoradiotherapy followed by adjuvant chemotherapy have been administrated to locally advance nasopharyngeal carcinoma according to the NCCN guidelines.This study s pecifically evaluated the efficacy,toxicity and compliance of modified concurrent chemoradiotherapy followed by adjuvant chemotherapy in locally advanced nasopharyngeal carcinoma(NPC).Methods:From Nov.2003 to Apr. 2005,67 patients with stageⅢandⅣlocally advanced nasopharyngeal carcinoma(NPC)were enrolled in this study.A total dosage of radiation,70-74 Gy,was given in 35-37 fractions in 5 fractions per week.Two cycles of chemotherapy, consisting of cisplatin 25 mg/m2?d-1 and 5-fluorouracil 300 mg/m2?d-1 were delivered simultaneously with radiotherapy on the day 1-3 during week 1 and 5.Three cycles of adjuvant chemotherapy,consisting of cisplatin 25 mg/m2?d-1 and fluorouracil 450 mg/m2?d-1,were also given,starting on day 1-3 during week 10,13 and 16.Results:The median follow-up was 20 months(ranged from 11 to 27 months).The 2-year overall survival rate and the 2-year diseasefree survival rate were 91.75%and 81.56%respectively.The 2-year overall survival rate was 96%for stageⅢand 87.65%for stageⅣ(P=0.334).The 2-year disease-free survival rate was 92.16%for stageⅢand 69.35%for stageⅣ respectively(P=0.2358).The compliance rates were 100%for radiotherapy,47 cases(70.1%)for all chemotherapy, 56 cases(83.6%)for concurrent chemotherapy and 48 cases(71.6%)for adjuvant chemotherapy.The main grade Ⅲ/Ⅳacute toxicity events during concurrent chemoradiotherapy were neutropenia in 15 patients(21.4%),vomitting and nausea in 2 patients(3%),mucositis in 56 patients(83.6%),and gradeⅢskin reaction in 10(15%),respectively. The main gradeⅢ/Ⅳacute toxicity events during adjuvant chemotherapy were neutropenia in 13 patients(19.4%), grade 3 anemia in 2 patients(1.5%)respectively.Conclusion:The primary result showed a good compliance,lower incidences of toxicity and improved early outcome of treatments for the patients with stageⅢand stageⅣ(M0)NPC. The ultimate therapeutic ratio will be updated according to longer follow-ups.

Fourteen critical patients were treated by total parenteral nutrition(TPN) or en- teral nutrition(EN) and good results were achieved.Among the1 4patients,1 0 cases were suffered from MSOF.The results suggest thatnutritional support is very im- portant for the critical patients,especially for their rehabilitation and prognosis.The use of TPN is not limited by the gastroin- testinal function.TPN should be sellected preferably when a patient is critical and se- rious.EN should be used when gastroin- testinal function have recovered in order to reduce the translocation of bacteria and en- dotoxin in the gut and decrease gastroin- testinal bleeding.

Objective To investigate the effects of titanium nitride(TiN) coating on corrosion resistance of dental Co-Cr alloy in the simulated oral environment. Methods The Co-Cr alloy commonly used was casted with specimen sized of 10 mm× 10 mm×3 mm. Then the specimen was coated with a thickness of 2.5 μm TiN coating on the surface by multi-arc physical vapor deposition. The Tafel polarization curves of the specimen before and after coating titanium nitride in artificial saliva were measured by electrochemical station. Results From the Tafel polarization curves, the specimen after coating TiN showed that both anodic polarization curve and cathodal polarization curve were fiat, natural corrosion potential moved to the positive way, and passivation interval got longer. From the annular anodic polarization curves, the specimen after coating TiN had almost no "delay area". Conclusion TiN coating can improve corrosion resistance of Co-Cr alloy.
