Effectiveness of extracorporeal shock wave therapy for frozen shoulder:a Meta-analysis / 中国组织工程研究

BACKGROUND:There is a lack of evidence about the application of extracorporeal shock wave therapy (ESVTr) in frozen shoulder contracture syndrome.OBJECTIVE:To systematically assess the effectiveness of EST for frozen shoulder.METHODS:A computer-based online search of PubMed,ScienceDirect,The Cochrane Library,Embase,Web of knowledge,CNKI,WanFang and CqVip databases was performed for articles related to ESWT for frozen shoulder published before May 10,2016.Randomized controlled trials or randomized controlled crossover trials were screened.The Meta-analysis was conducted using RevMan 5.0 software,and publication bias was assessed by Berg and Egger tests on Stata1 1.0 software.The continuous variables were expressed as standard mean difference (SMD) and 95％ confidence interval (CI),and binary variables were expressed as odds ratio (OR) and 95％ Cl.RESULTS AND CONCLUSION:Eleven trials were enrolled involving 816 participants.ESWT could effectively alleviate shoulder pain (P ＜ 0.05,/2=54％).When excluded the trials of which control groups were medical interventions,the direction of the outcome did not change.ESVVT was beneficial for the participants in terms of range of motion except extension,the changes in shoulder flexion (P ＜ 0.05,/2=28％),shoulder abduction (P ＜ 0.000 01,/2=17％),shoulder internal rotation (P ＜ 0.05,/2=0％),shoulder external rotation (P ＜ 0.05,/2=43％).However,there is no evidence of the effectiveness of ESWT versus control (conventional therapy) for improving the range of shoulder extension.ESWT could increase the efficiency of treating frozen shoulder (P ＜ 0.05,/2=0.0％) and efficacy of curing frozen shoulder (P ＜ 0.05,/2=0.0％) compared with other interventions,and with no significant difference in the drop rate.These results indicate that ESWT can effectively alleviate the pain of frozen shoulder,expand the range of shoulder flexion,abduction,internal and external rotation,as well as improve the therapeutic efficiency and cure rate in the treatment of frozen shoulder.

Sodium tanshinone II A sulfonate ameliorates microcirculatory disturbance of small intestine by attenuating the production of reactie oxygen species in rats with sepsis / 中国结合医学杂志

<p><b>OBJECTIVE</b>To examine whether sodium tanshinone II A sulfonate (STS), the main effective component of Salvia miltiorrhiza is effective in relieving the microcirculatory disturbance of small intestine by suppressing the production of reactive oxygen species (ROS) in rats with sepsis.</p><p><b>METHODS</b>A rat model of sepsis was induced by cecal ligation and puncture (CLP). Rats (n =40) were randomly divided into 4 groups: sham-operated group (sham, n =10), sepsis group (CLP, n =10), STS treatment group (STS, n =10) and ROS scavenger dimethylthiourea (DMTU, n =10) group. Animals in the STS group were injected with STS (1 mg/kg) for 10 min through the right external jugular vein after the CLP operation, and animals in the CLP group were given the same volume of normal saline after the CLP operation. Animals in the DMTU group were intraperitoneally injected with 5 mL/kg of 20% DMTU 1 h before CLP. The histopathologic changes in the intestinal tissues and changes of mesenteric microcirculation were observed. The levels of ROS in intestinal tissues from each group were qualitatively evaluated using a fluorescent microscope. The expressions of apoptosis signal-regulating kinase (ASK1), phosphorylated ASK1 (phospho-ASK1), p38 mitogen-activated protein kinases (p38 MAPK), phosphorylated p38 MAPK (phospho-p38 MAPK) and tissue factor (TF) were determined by Western blotting.</p><p><b>RESULTS</b>It was shown that there were obvious microcirculatory disturbance (P <0.05) and tissue injuries in intestinal tissues after CLP operation. The levels of ROS production, phospho-ASK1, phospho-p38 MAPK and TF were increased. Both STS and DMTU suppressed ROS, phospho-ASK1, phospho-p38 MAPK and TF production, and ameliorated the microcirculatory disturbance and tissues injury (P <0.01).</p><p><b>CONCLUSION</b>STS can ameliorate the microcirculatory disturbance of the small intestine by attenuating the production of ROS in rats with sepsis.</p>

Protective effect of tanshinone II a on myocardial apoptosis in rats with sepsis / 中国药学杂志

OBJECTIVE: To explore the effect of tanshinone II A (Tan II A) on the myocardial apoptosis in rats with sepsis. METHODS: The sepsis rat model was established by cecal ligation and puncture operation (CLP), and the Tan II A was given for 12 consecutive hours. Then, the following indices were measured such as the activities of Na+-K+-ATPase and SOD, the contents of TNF-α, IL-1β, calcium, MDA, apoptotic index and the protein level of Bcl-2, Bax, Fas, caspase-3, calcincurin in myocardial. RESULTS: CD Compared with sham group, CLP treatment can result in decreased myocardial activities of Na+-K+-ATPase and SOD, elevated the contents of IL-1β, calcium, MDA (P<0.05); Tan II A treatment can improve the above aberrant indices. (2) Compared with sham group, CLP treatment can elevated the myocardial apoptotic index (P<0.05), and Tan II A treatment can decrease the elevation of apoptotic index by CLP treatment (P<0.05); (3)Compared with sham group, the protein level of Bax, Fas, caspase-3 and calcincurin significantly increased, and protein level of Bcl-2 decreased (P<0.05) in CLP group, and Tan II A treatment can improve exceptional expression of the above proteins (P<0.05). CONCLUSION: Tanshinone II A shows a protective effect on the myocardial apoptosis in septic rats maybe by depressing inflammatory infiltration and oxidative stress reaction, relieving calcium overload and partly improving the exceptional expression of the proteins such as Bax, Bcl-2, Fas, caspases-3 and calcincurin.

Protective effect of sodium tanshinone IIA sulfonate on injury of small intestine in rats with sepsis and its mechanism / 中国结合医学杂志

<p><b>OBJECTIVE</b>To explore the protective effect of sodium tanshinone IIA sulfonate (STS) on small: intestine injury in rats with sepsis and its possible mechanism.</p><p><b>METHODS</b>According to a random number table, 24 Tats were randomly divided into 3 groups: sham operation group (sham group), sepsis model group (model group) and STS treatment group (STS group), with 8 Tats in each group. A rat model of sepsis was induced by cecal ligation and puncture (CLP) for 5 h. STS (1 mg/kg) was slowly injected through the right external jugular vein after CLP. The histopathologic changes in the intestine tissue were observed under a light microscope, and the intestinal epithelial cell apoptosis was evaluated by terminal deoxynucleoddyl transferase (TdT)-mediated dUTP nick-end labeling (TUNEL) method. The expressions of Bcl-2, Bax and nuclear factor κB (NF-κB) p65 in the intestinal tissue was determined by Western blot. The levels of tumor necrosis factor α (TNF-α) and interleukin 6 (IL-6) in the intestinal tissue were determined using enzyme-linked immuno-sorbent assay (ELISA).</p><p><b>RESULTS</b>Obvious injuries were observed in the intestinal tissue in the CLP group compared with the sham group. The expression of NF-κB p65 and the levels of TNF-α and IL-6 were up-regulated after CLP, the apoptosis of intestinal epithelial cells was increased after CLP, and the ratio of Bcl-2 to Bax was decreased. STS post-treatment could attenuate the injury on the intestinal tissue induced by CLP, decrease the apoptosis of intestinal treatment epithelial cells and the levels of NF-κB p65, TNF-α and IL-6, and increase the ratio of Bcl-2 to Bax.</p><p><b>CONCLUSION</b>STS can protect the small intestine in rats with sepsis, and the mechanism may be associated with the inhibition of intestinal epithelial apoptosis and the reduction of activation of inflammatory cytokines.</p>
