The cell surface antigens and the ability of CFU GM proliferation of mPEG modified cord blood lymphocytes were analyzed. Flow cytometric analysis demonstrated that mPEG modified lymphocytes attenuated CD3, CD4 and CD8 antibodies binding to antigens on lymphocyte surface ( P

Objective To observe the clinical efficacy of triple needling at myofascial trigger points plus warm needling in treating periarthritis of shoulder. Method Eighty patients with periarthritis of shoulder were randomized into a treatment group of 44 cases and a control group of 40 cases. The treatment group was intervened by triple needling at myofascial trigger points plus warm needling, while the control group was by warm needling alone. The two groups were treated once a day, 10 times as a treatment course. The Pain Rating Index (PRI), Visual Analogue Scale (VAS), Present Pain Intensity (PPI), and motion of shoulder joint were observed before the treatment and after 2 treatment courses, and the clinical efficacies were compared between the two groups.Result In the treatment group, the PRI, VAS, and PPI scores respectively after 1 and 2 treatment courses were significantly different from those before the treatment (P<0.05,P<0.01). In the control group, the scores after 2 treatment courses were significantly different from those before the treatment (P<0.05). After 2 treatment courses, the scores in the treatment group were significantly different from those in the control group (P<0.01). In both groups, the motions of shoulder joint respectively after 1 and 2 treatment courses were significantly changed compared with those before the treatment (P<0.01). The motions of shoulder joint in the treatment group were significantly different from those in the control group respectively after 1 and 2 treatment courses (P<0.05,P<0.01). The recovery plus markedly-effective rate and total effective rate were respectively 70.5% and 95.5% in the treatment group, versus 52.5% and 90.0% in the control group, and the between-group differences were statistically significant (P<0.01,P<0.05).Conclusion Triple needling at myofascial trigger points plus warm needling is an effective approach in treating periarthritis of shoulder.

Objective To evaluate the diagnostic value of the recombinant protein Sj_Ts4 in immunodiagnosis of Schistosomiasis japonica.Methods Seventy-four blood samples of schistosomiasis japonica patients(acute, chronic and advanced)were used for evaluating the sensitivity.Blood samples from 24 Clonorchiasis patients,8 patients with hookworm infections and 30 normal persons from the areas without Schistosomiasis were used ror patients.Results The positivity rates were 97.1%(33/34),100.0%(16/16),87.5%(21/24)in rSj-Ts4-ELISA and 100%(34/34),100.0%(16/16),75.0%(18/24)in SjAWA-ELISA in acute,chmnic and advanced Schistosomiasis. respectively.Statistical analysis revealed no significant difference in sensitivity(X2=1.23,P＞0.05)between both recombinant and crude antigens.The false positive reaction was found to be 6.7%(2/30)in rSj-Ts4-ELISA and 3.3%(1/30)in SjAWA-ELISA when detected in 30 cases of normal control sera.but no statisticallv significant difference was noted(x2=0.35,P＞0.05).Twelve point five percent(3/24),20.8%(5/24)and 12.5%(1/8),37.5% (3/8),of cross-reactions were observed between rSj-Ts4-ELISA and SjAWA-ELISA for detecting the sera of patients with clonorehiasis and hookworms.There was no significant difference of cross-reaction in two parasitic infections (x2=0.60,1.33,P＞0.05)with the two tests.Conclusions The rSj-Ts4 antigen shows higher sensitivity and specificity for the diagnosis of Schistosomiasis japonica,which is helpful in the serological diagnosis of Schistosomiasis japonica in endemic areas.

Objective To measure the vitamin B1 levels in plasma,erythrocytes and urine of the patients with type 2 diabetes,and to analyze the correlation of vitamin B1 level with the progression of diabetic nephropathy,and to clarify the metabolism of nutrtion mechanism of type 2 diabetic nephropathy.Methods Total 90 patients with type 2 diabetes and 30 healthy volunteers were recruited.According to the levels of microalbuminuria,the patients with type 2 diabetes were divided into non diabetic nephropathy (NDN)group,early diabetic nephropathy (EDN)group and clinical diabetic nephropathy (CDN)group (n=30);the healthy people was used as normal control (NC) group.The vitamin B1 levels in the plasma,erythrocytes and urine were examined with high performance liquid chromatography (HPLC). The correlation of microalbuminuria with the plasma viamin B1 level was analyzed. Results The level of vitamin B1 in plasma of the patients in NC group was (7.1±3.3)μg·L-1,while it was (4.0±2.3)μg·L-1 in NDN group,(3.1±1.0)μg·L-1 in EDN group and (2.3±0.6)μg·L-1 in CDN group. Compared with NC group,the vitamin B1 levels in the plasma in NDN,EDN and CDN groups dropped 43.7%, 56.3%,and 67.6%,respectively (P<0.05). The excretion of vitamin B1 in urine were (2.9 ± 0.8),(9.0 ± 4.7),(11.7±3.9),and (15.6±5.0)μg·L-1 in NC group,NDN group,EDN group and CDN group, respectively.Compared with NC group,the vitamin B1 levels in the urine in NDN,EDN and CDN groups were increased by 2,3 and 4 times,respectively (P<0.05).A negative correlation was found between the level of microalbuminuria and the level of vitamin B1 in plasma (r=-0.62,P=0.013).Conclusion Vitamin B1 deficiency can be observed in the early stage of diabetic nephropathy,and the level of vitamin B1 is closely correlated with the progression of diabetic nephropathy.

Deep venous thrombosis (DVT) is initiated intraoperatively and may display symptoms postopera- tively following total hip or total knee arthroplasties. Pulmonary embolism (PE) and DVT cause morbidity and mortality. It has been established that patients who undergo a major lower-extremity joint replacement should receive prophylaxis due to the increased risk of DVT. Despite use of thrombo-prophylaxis, elective replacement surgery carries a high risk of venous thromboembolic complications. The early detection of DVT and treatment with systemic anticoagulation to pre- vent DVT are essential in the management of patients undergoing total joint arthroplasty. Extended medical throm- bo-prophylaxis is indicated for some high-risk patients. Routine postoperative duplex surveillance for DVT may be clinically useful. In the early post-operative phase, combined prophylaxis such as low-molecular-weight heparins and mechanical methods may be more effective than single intervention measures. However, the efficacy and safety of an- ticoagulation therapy, using various medicines administered after total arthroplasty of large joints are still undetermined and controversial.We should also be alert to the frequency and extent of postoperative hematomas. There are still many uncertainties in treatments to prevent DVT in terms of safety and cost-effectiveness. Therefore, prospective, ran- domised, controlled and multicenter studies may be necessary to obtain valuable information according to evidence based medicine.

Objective To investigate the correlation between nuclear factor(NF)-?B and inflammation of cell in adriamycin-induced nephritic rats,and the intervention of antisense oligonucleotide targeting NF-?B to adriamycin-induced nephritic rats by measuring the expression of NF-?B p65 in renal cortex and the secretions of interleukin-6(IL-6),tumor necrosis factor-?(TNF-?)in serum.Methods Thirty male SD rats were divided into 5 groups(6 rats in each group):group A(sham operation),group B(glomerulosclerosis),group C(sense oligonucleotide),group D(non-sense oligonucleotide),group E(antisense oligonucleotide).Glomerulosclerosis models were made for SD rats by unilateral nephrectomy and being injected with adriamycin into caudal vein.In the 8th week,various medicine applys to correspon-ding group for intervention.At the 4th day and 8th day after intervention,the excretion amounts of 24 hours urine protein were determined.Hematoxylin-Eosin(HE) staining was used to observe the renal pathological changes.Using image analysis system to calculate glomerulosclerosis index(GI).The expression of NF-?B p65 in renal cortex was measured by immunohistochemistry staining,the secretions of IL-6,TNF-? in serum were performed by means of enzyme-linked immunosorbnent assay,respectively.Results At different time points,the expressions of active-NF-?B p65,IL-6,TNF-? in group E were significantly lower than those in group B.The intervention effects of antisense oligonucleotides at the 8th day were stronger than that at the 4th day.Conclusions NF-?B is significantly correlated with glomerulosclerosis and inflammations of glomerular intrinsic cells.Using NF-?B antisense oligonucleotide to be injected into renal artery can block directly the translation of NF-?B gene,delay inflammations of glomerular intrinsic cells and the progressions of glomerulosclerosis.

A bacterium(designated as LW-3), capable of degrading Chlorimuron-ethyl, was isolated from the long-term contaminated soil by Chlorimuron-ethyl. Based on physiological and biochemical analyses and sequences comparison of 16S rDNA, strain LW-3 was identified as Pseudomonas sp. LW-3 could use Chlorimuron-ethyl as sole nitrogen source for growth. The optimum pH and temperature for degradation of Chlorimuron-ethyl were pH 6.5~7.2 and 30?C~35?C, at same temperature the pH change to the Chlorimuron -ethyl degrading influence is large. When the pH and temperature were pH 6.5 and 32?C, 50 mg/L Chlori- muron-ethyl could be degraded to 70%~80% level within 7 days.
