Effect of Kinesio Taping on Knee Osteoarthritis: A Meta-analysis / 中国康复理论与实践

Objective:To evaluate the effect of Kinesio taping on knee osteoarthritis (KOA). Methods:The Cochrane Library, PubMed, CNKI, Web of Science and PEDro were searched from inception to November, 2018. The randomized controlled trials (RCTs) about the effect of Kinesio taping on knee osteoarthritis were collected. Two reviewers independently screened articles according to the inclusion and exclusion criteria, extracted data and evaluated the quality of the included studies. Meta-analysis was performed using RevMan 5.3. Results:A total of six RCTs were enrolled. There were significant differences in the scores of Visual Analogue Score between the intervention group and the control group (WMD = -1.28, 95%CI -2.36 to -0.20, P = 0.02). There were no significant differences in Western Ontario and McMaster Universities Osteoarthritis Index, range of motion, quadriceps femoris and hamstring muscle strength between the intervention group and the control group (P > 0.05). The other studies only adopted descriptive analysis accordingly. Conclusion:It is still uncertain in the effectiveness of Kinesio taping on knee osteoarthritis.

Effects of Electroacupuncture on Skeletal Muscle Atrophy-associated Protein in Hind Limbs of Traumatic Spinal Cord Injury Rats / 中国康复理论与实践

Objective:To explore the effects and mechanism of electroacupuncture (EA) on expression of myostatin (MSTN), muscle-specific ring finger protein 1 (MuRF1/Trim63), F-box only protein 32 (Atrogin-1/ Fbxo32), myogenic differentiation antigen (Myod) and myogenin (Myog) in traumatic spinal cord injury (TSCI) rats. Methods:A total of 45 adult female Sprague-Dawley rats were randomly divided into sham operation group (n = 12) and operation group (n = 33). The TSCI model was established with the modified Allen's method. After modeling, there were 24 survival rats and they were randomly divided into model group (n = 12) and EA group (n = 12). EA group was electroacupunctured at Dazhui (DU 14), Mingmen (DU 4) and bilateral Zusanli (ST 36) for 10 minutes, once a day, six times a week for 28 days. Basso-Beattie-Bresnahan (BBB) score was tested before modeling, and three days, seven days, 14 days, 21 days and 28 days after modeling. The rats were measured their body mass before and 28 days after modeling. The ratio of gastrocnemius wet mass was calculated; the cross-sectional area (CSA) and fiber diameter were measured by HE staining; the expression of MSTN, Trim63, Fbxo32, Myod and Myog mRNA were tested with real-time quantitative polymerase chain reaction (qPCR). Results:Three days, seven days, 14 days, 21 days, and 28 days after modeling, the score of BBB was lower in the model group than in the sham operation group (P < 0.01); seven days, 14 days, 21 days, and 28 days after modeling, the score of BBB was higher in EA group than in the model group (P < 0.01). Compared with the sham operation group, the mass of rats, the gastrocnemius wet mass, the CSA and the diameter of the muscle fiber were smaller in the model group (P < 0.05), while the expression of MSTN, Trim63, Fbxo32, Myod and Myog mRNA were higher (P < 0.05). Compared with the model group, the mass of rats, the gastrocnemius wet mass, the CSA, the expression of Myod and Myog mRNA were higher (P < 0.05) in EA group, while the expression of MSTN, Trim63 and Fbxo32 mRNA were lower (P < 0.05). Conclusion:EA might delay the gastrocnemius atrophy in TSCI rats by down-regulating the expression of MSTN, Trim63, Fbxo32 mRNA and up-regulating the expression of Myod and Myog mRNA via controlling the differentiation of the muscle satellite cells and the degradation of protein in skeletal muscle cells.

Effect of danshensu on JNK and NF-kappaB signal transduction of rat hepatic stellate cells induced by interleukin-1beta / 南方医科大学学报

<p><b>OBJECTIVE</b>To investigate the inhibitory effect of danshensu on c-Jun N-terminal kinase (JNK) and nuclear factor-kappa B (NF-kappaB) signaling in activated rat hepatic stellate cells (HSCs) and explore the mechanisms of danshensu for inhibiting hepatic fibrosis.</p><p><b>METHODS</b>MTT colorimetric assay was used to detect the proliferation of rat HSCs treated with danshensu, and the apoptosis of the cells was analyzed with Annexin- V-FITC/PI and AO/EB staining. The expressions of P-IkappaB-alpha, NF-kappaBP65 and JNK in HSCs stimulated by IL-1beta with subsequent danshensu treatment were observed by Western blotting. Type III collagen in the medium of HSCs was detected by ELISA and immunocytochemistry.</p><p><b>RESULTS AND CONCLUSIONS</b>Danshensu inhibited the activation and proliferation of HSCs, and increased the apoptotic rate of HSCs and reduced the synthesis and secretion of type III collagen. Danshensu showed obvious inhibitory effect on JNK and P-IkappaB-alpha phosphorylation and NF-kappaBP65 expression in HSCs stimulated by IL-1beta. The mechanism of the actions of dansgensu may be mediated by inhibition of JNK and NF-kappaB signal transduction.</p>

Advances in the study of the microbial efflux pumps and its inhibitors development / 药学学报

Drug resistant bacteria is an increasingly urgent challenge to public health. Bacteria adaptation and extensive abuse of antibiotics contribute to this dilemma. Active efflux of antibiotics is employed by the bacteria to survive the antibiotic pressure. Efflux pump is one of the hot spots of current drug related studies and ideal targets for the improvement of treatment. The efflux pumps and related mechanisms of action, regulation of expression and methodologies were summarized. Comparative genomics analyses were employed to elucidate the underlying mechanisms of action and evolution of efflux pump as exemplified by the Mycobacterium in our lab, which is a crucial re-emerging threat to global public health. The pathway and state-of-art drug development of efflux pump related drugs are included too.

Association of galectin-3 and E-cadherin expressions with lymph node metastasis of colon cancer / 南方医科大学学报

<p><b>OBJECTIVE</b>To explore the correlation between the expressions of galectin-3 and E-cadherin and lymph node metastasis of colon cancer.</p><p><b>METHODS</b>Immunohistochemistry was employed to examine the expressions of E-cadherin and galectin-3 in 37 colon cancer samples, among which 21 samples underwent RT-PCR for E-cadherin and galectin-3 mRNA expressions. The correlation of E-cadherin and galectin-3 expressions with lymph node metastasis of the tumor was analyzed.</p><p><b>RESULTS</b>The positivity rate of galectin-3 expression was 83.8% (31/37) in these samples. Of the tumor cases with lymph node metastasis, 94.7% (18/19) of the tumors were positive for galectin-3 expression, a rate significantly higher than that in non-metastatic cases. The positivity rate of E-cadherin expression was 59.5% (22/37) in the total cases, and 47.4% (9/19) in the metastatic cases, significantly lower than that in the non-metastatic cases.</p><p><b>CONCLUSION</b>Galectin-3 and E-cadherin expressions are associated with lymph node metastasis of colon cancer and may serve as potential prognostic indicators for colon cancer patients.</p>
