Objective:To observe the clinical efficacy of combining neuromuscular joint facilitation (NJF) with floating needle treatment in treating stroke survivors with painful shoulder subluxation.Methods:Thirty-nine stroke survivors with painful shoulder subluxation were randomly divided into an NJF group, a floating needle group and a combination group, each of 13. In addition to the basic treatment for shoulder subluxation and pain (including positioning, physiotherapy, active and passive motor function training, progressive training of the upper limbs, and using shoulder pads to protect the affected shoulders when standing or walking), the 3 groups were also given NJF, floating needle therapy or both as their group names imply six days per week for 4 weeks. Shoulder subluxation was evaluated using ultrasonography to measure the acromion-greater tuberosity distance (AGT). Pain was self-reported using a visual analogue scale. And the Fugl-Meyer assessment (FMA) was applied to quantify the treatments′ efficacy.Results:Before the treatment, no significant differences were found among the 3 groups in terms of their average AGTs, pain ratings or FMA scores. Afterward, significant improvement was observed in all of the measurements in all 3 groups, with the combination group′s average results significantly better than those of the other two. The combination group′s overall effectiveness was 85%, significantly better than that of NJF group (54%) and the floating needle group (62%).Conclusions:Floating needle treatment combined with NJF and routine rehabilitation can significantly improve motor functioning and relieve the pain of shoulder subluxation after a stroke.

Objective To investigate the serum levels of tumor markers CEA,CA724,PGⅠ,PGⅡ,PGI/PGII and SF in gas-tric cancer.Methods The serum levels of CEA,CA724,PGⅠ,PGⅡ,PGI/PGII and SF were detected in 46 healthy con-trols,45 atrophic gastritis patients and 39 gastric cancer patients.Serum levels of CEA,CA724 were measured by ELC meth-od,PGⅠ,PGⅡ by time resolved fluorescence immunoassay (TRFIA)and SF by immunoturbidimetry(ITM).Results ①Compared to the healthy controls,the statistical contrast of serum levels of CEA,CA724,PGⅠ,PGⅡ and PGI/PGII except SF was significant in gastric cancer patients(P<0.05),only PGⅠ,PGⅡ,SF had significant difference in atrophic gastritis patients (P<0.05).Compared to atrophic gastritis patients,the serum levels of CEA,CA724 were significantly higher,but PGⅠwas lower in gastric cancer patients(P<0.05).②When CEA,CA724,PGⅠ,PGⅡ,PGI/PGII and SF were used to di-agnose gastric cancer individually,the sequence of the area under ROC curve was CEA,SF,CA724,PGI/PGII,PGⅡ and PGⅠ.Only the areas of PGⅠ,PGⅡunder ROC curve had significant statistical difference (P<0.05).③The sensitivity,speci-ficity,PPV and NPV were different when these indexes were used to diagnize gastric cancer individually or incorporatedly. Conclusion The serum levels of tumor markers CEA,CA724,PGⅠ,PGⅡ,PGI/PGII and SF had important reference value for the diagnosis of gastric cancer although the diagnostic value was different individually or incorporatedly;the content of serum PG and the ratio of PGI/PGII were closely related to the gastric mucosa.

Objective To investigate the immune response to and protective effect of a bivalent DNA vaccine expressing interleukin-2(IL-2)and Gpd proteins in New Zealand rabbits.Methods Seventy-two male New Zealand white rabbits were equally and randomly divided into 4 groups to be immunized with recombinant plasmids pcDNA3.1(+)/Gpd-IL-2(pcD/Gpd-IL-2),pcDNA3.1(+)/Gpd(pcD/Gpd),empty plasmid pcDNA3.1(+)(pcD)and phosphate buffered saline(PBS),respectively.Immunization was carried out by intramuscular injection at multiple sites with a 2-week interval for 3 times.On week 10 after the initial immunization,the rabbits were challenged intradermally with T.pallidum(Nichols strain).Enzyme-linked immunosorbent assay(ELISA)was used to quantify the serum level of anti-Gpd antibodies in the rabbits and the level of IL-2 and interferon(IFN-γ)in the supernatant of Gpd protein-stimulated spleen cells from the rabbits at different time pionts.MTT assay was conducted to detect the proliferation response of spleen cells collected from the rabbits on day 0,14,28,140 and 168 after the challenge.Results Compared with pcD and PBS,both the vaccines pcD/Gpd and pcD/Gpd-IL-2 elicited significantly higher levels of anti-Gpd IgG antibodies in rabbits at different time points during the vaccination and infection period,with the titers peaking at 1 ∶ 1024 and 1∶4096,respectively(both P ＜ 0.01).There were also significant differences in the serum levels of anti-Gpd IgG antibodies between the pcD/Gpd-and pcD/Gpd-IL-2-immunized rabbits at different time points(all P ＜0.01).The levels of IL-2 in the supematant of spleen cells from pcD/Gpd-and pcD/Gpd-IL-2-immunized rabbits on week 8 after the immunization were 110 ± 12.6 and 167 ± 15.7 μg/L respectively,and those of IFN-γwere 225 ± 17.6 and 447 ± 22.4 μg/L respectively,significantly higher than those in that from the other two groups of rabbits(all P ＜ 0.01).Furthermore,an apparent proliferation response was observed in spleen cells from pcD/Gpd-and pcD/Gpd-IL-2-immunized rabbits with a higher stimulation index compared with pcD-and PBS-immunized rabbits(all P ＜ 0.01).Dark-field microscopic examination of early-stage infected lesions revealed that pcD/Gpd-IL-2-immunized rabbits had a lower detection rate(17.5％)of Tp from lesions,occurrence of ulcerative lesions(15％)and shorter curing time compared with pcD/Gpd-immunized rabbits.Conclusion The recombinant plasmid pcDNA3.1(+)/Gpd-IL-2 could induce protective humoral and cellular immune response more efficiently in rabbits.
