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.

AIM:To analyze the effect 17?-estradiol on activated macrophages and possibility of being a target of screening drugs for endometriosis. METHODS: Using scanning electron microscope, the surface of macrophages was observed. Nitric oxide (NO) in supernatant was determined by Griess's reagent. TNF-? was measured by MTT via L929 cells. Using Fluo-3/AM, i was measured by laser scanning confocal microscopy (LSCM). RESULTS: (1) Increased size, extension of more microvilli, expression of retraction fibers and elaboration of membrane ruffles were detected in 17?-estradiol treated macrophages. (2) 17?-estradiol induced NO release from peritoneal macrophages. (3)The more TNF-? was made by macrophages under the induction of 17?-estradiol. (4)Intracellular Ca 2+ elevated 39.8% in peritoneal macrophages after 17?-estradiol (100 nmol/L) treatment. CONCLUSIONS: Macrophages were activated by 17?-estradiol at a certain concentration. Activated macrophages by 17?-estradiol may participate in endometriosis and may be a target of screening drugs for endometriosis.

Objective To explore the clinical significance of monocyte chemoattractant protein-1(MCP-1)in children with Henoch-Schonlein purpura nephritis(HSPN).At the same time compare the association between serum and urine MCP-1,to investigate the impact of the both on them in children with HSPN.Methods Serum and urine MCP-1 were measured by enzyme linked immunosorbent assay in 50 children with Henoch-Schonlein purpura(HSP)(25 cases of them patients with renal injures),and 25 healthy children,the changes of serum and urine MCP-1 were compared;at the same time serum urea nitrogen,creatinine,urinary albumin,urine N-acetyl-D-glucosaminidase(NAG),urine ?2-MG,24 hours urinary levels of protein were investigated in children with HSPN by analyzing the correlation between these indicators and serum and urine MCP-1;urine MCP-1 in HSPN group were measured in recovery period,and were compared with urine MCP-1 in HSP group and HSPN group in acute period.Results 1.The expressions of urine MCP-1 was significantly higher in HSPN group than those in HSP group and healthy controls(P0.05).2.Urine MCP-1 levels were associated with proteinuria in children with HSPN,but serum MCP-1 levels had nothing to do with HSPN.3.There was a close correlation between urine MCP-1 expression and urinary albumin,urine NAG,urine ?2-MG and 24 hours urinary levels of protein,but the expression of urine MCP-1 levels were not correlated with the serum urea nitrogen and creatinine.4.There was statistical significance in urine MCP-1 in acute and recovery periods with HSPN group(P

Objective: To clone the cDNA of human sPLA2-IIA,construct the engineered Escherischia coli expressing human sPLA2-IIA and identify the expressed human sPLA2-IIA. Methods: Total RNAs were purified from human fetal spleen. The cDNA of human sPLA2-IIA was cloned by RT-PCR and inserted into plasmid pET32a(+) between NcoI and EcoRI sites for expressing the recombinant human sPLA2-IIA in Escherischia coli BL21(DE3). The recombinants were screened by SDS-PAGE. The engineered Escherischia coli expressing trxA-human sPLA2-IIA fusion protein was established. The expressed human sPLA2-IIA exists in the form of inclusion body and accounts for about 25% of the total proteins of Escherischia coli BL21(DE3). Conclusion: the engineered E. coli methods are suitable for preparing plenty of human sPLA2-IIA which has laid base for the large-scale expression,purification and basic studies of human sPLA2-IIA.

Phytoene synthase is a rate-limiting enzyme in the pathway of carotenoid biosynthesis.To aim at establishing a transformation of Ginseng callus cells, elevating the nutritive value through encouraging the composition of corresponding carotenoid,taking Ginseng callus cells as acceptor,psy gene were transformed into cells via Agrobacterium-mediated. The factors affecting genetict ransformation were also investigated seperately from concentrations of A.tumefaciens, age of Ginseng callus cells, infection time and co-culture time. PCR,PCR-Southern and RT-PCR analysis from the transferred gene plants proved that psy gene has been transferred into Ginseng callus cells and can be expressed. The content of ?-carotene was increased by an average of 26 times.A base of improving and raising the contents of carotenoid in the Ginseng callus cell was established.

Objective: To observe the clinical efficacy of electroacupuncture (EA) plus Tanbo-plucking the trigger points for scapulohumeral periarthritis (SP). Methods:A total of 80 patients with SP were randomized into an observation group and an EA group by the random number table, with 40 cases in each group. The EA group was treated with EA therapy, and the observation group was treated with EA therapy plus Tanbo-plucking the trigger points. After treatment, the visual analog scale (VAS) and Melle scores of the two groups were compared to evaluate the improvement of shoulder pain and functional activity, and meanwhile the clinical efficacy was observed. Results: After treatment, the total effective rate of the observation group was 95.0％ and the cure and markedly effective rate was 72.5％. The total effective rate of the EA group was 87.5％ and the cure and markedly effective rate was 42.5％. There was no significant difference in the total effective rate between the two groups (P>0.05). The cure and markedly effective rate of the observation group was higher than that of the EA group, and the difference between the two groups was statistically significant (P<0.05). After treatment, the intra-group differences in VAS and Melle scores of both groups were statistically significant (bothP<0.001). The inter-group differences in the changes of the VAS and Melle scores after treatment were statistically significant (bothP<0.001). Conclusion: EA plus Tanbo-plucking the trigger points has a better curative effect than EA therapy alone in the treatment of SP.

Objective To observe the changes of expression and activity of heme oxygenase-1(HO-1) in lung tissue of preterm rats exposed to hyperoxia,and explore the role of HO-1 in hyperexia-induced lung injury of preterm rats.Methods Three-day-old preterm rats of standard SD were randomly assigned to hyperoxia group and air group.At the third and 7th day of exposure,the expressions of HO-1 mRNA were detected by means of reverse transcription polymerase chain reaction and the cellular distribution and expressions of HO-1 protein in the lung were measured by immunohistochemical techniques,respectivesly,and the active of HO-1 was determined also.Results On the third day,in air group,the expressions of HO-1 mRNA(0.17 ?0.08),HO-1(7.23?4.63)were mildly expressed and the activity of HO-1 was(4.32?1.57) nmol/(mg?h);compared with those of air group,the expression of HO-1 mRNA in hyperoxia group(0.72?0.33) was significantly increased(Pa
