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.

Blockade of Endogenous Angiotensin-(1-7) in Hypothalamic Paraventricular Nucleus Attenuates High Salt-Induced Sympathoexcitation and Hypertension / 神经科学通报·英文版

Angiotensin (Ang)-(1-7) is an important biologically-active peptide of the renin-angiotensin system. This study was designed to determine whether inhibition of Ang-(1-7) in the hypothalamic paraventricular nucleus (PVN) attenuates sympathetic activity and elevates blood pressure by modulating pro-inflammatory cytokines (PICs) and oxidative stress in the PVN in salt-induced hypertension. Rats were fed either a high-salt (8% NaCl) or a normal salt diet (0.3% NaCl) for 10 weeks, followed by bilateral microinjections of the Ang-(1-7) antagonist A-779 or vehicle into the PVN. We found that the mean arterial pressure (MAP), renal sympathetic nerve activity (RSNA), and plasma norepinephrine (NE) were significantly increased in salt-induced hypertensive rats. The high-salt diet also resulted in higher levels of the PICs interleukin-6, interleukin-1beta, tumor necrosis factor alpha, and monocyte chemotactic protein-1, as well as higher gp91 expression and superoxide production in the PVN. Microinjection of A-779 (3 nmol/50 nL) into the bilateral PVN of hypertensive rats not only attenuated MAP, RSNA, and NE, but also decreased the PICs and oxidative stress in the PVN. These results suggest that the increased MAP and sympathetic activity in salt-induced hypertension can be suppressed by blockade of endogenous Ang-(1-7) in the PVN, through modulation of PICs and oxidative stress.

Chronic Intracerebroventricular Infusion of Metformin Inhibits Salt-Sensitive Hypertension via Attenuation of Oxidative Stress and Neurohormonal Excitation in Rat Paraventricular Nucleus / 神经科学通报·英文版

Metformin (MET), an antidiabetic agent, also has antioxidative effects in metabolic-related hypertension. This study was designed to determine whether MET has anti-hypertensive effects in salt-sensitive hypertensive rats by inhibiting oxidative stress in the hypothalamic paraventricular nucleus (PVN). Salt-sensitive rats received a high-salt (HS) diet to induce hypertension, or a normal-salt (NS) diet as control. At the same time, they received intracerebroventricular (ICV) infusion of MET or vehicle for 6 weeks. We found that HS rats had higher oxidative stress levels and mean arterial pressure (MAP) than NS rats. ICV infusion of MET attenuated MAP and reduced plasma norepinephrine levels in HS rats. It also decreased reactive oxygen species and the expression of subunits of NAD(P)H oxidase, improved the superoxide dismutase activity, reduced components of the renin-angiotensin system, and altered neurotransmitters in the PVN. Our findings suggest that central MET administration lowers MAP in salt-sensitive hypertension via attenuating oxidative stress, inhibiting the renin-angiotensin system, and restoring the balance between excitatory and inhibitory neurotransmitters in the PVN.

Surgery for benign breast diseases through areolar incision / 中华内分泌外科杂志

Objective To explore the indications, superiority and surgical technique of periareolar approach in the management of benign breast diseases. Methods 132 patients with benign breast disease (91 cases of Fibroadenoma, 12 cases of limited gland hyperplasia, 8 cases of cyst, 2 cases of benign phyllodes tumor and 6 cases of male gynecomastia) underwent operation through areolar incision. Results All patients were followed up for 1-10 months. 107 cases were satisfied with their treatment,19 cases were not quite satisfied with the relatively long incision, and 6 cases were not satisfied with the front incision. The one-month-later reexamination showed that 117 cases feel good and 15 cases had partial numbness of the nipple (15/132, 11.36%). All but two patients wound healing delayed because of local hematoma (2/132, 1.52%). Neither necrosis nor infection was found. Conclusions With the advantages of fewer complications and cosmetic effect, periareolar approach can be applied in management of various benign breast diseases. Factors such as indications, anatomical layer, postoperative molding, appropriate drainage, pressure dressing should be taken into consideration for the success of operation.

Laparoscopic colorectal resection combined with simultaneous radiofrequency ablation for liver metastases / 中华消化外科杂志

Objective To assess the clinical value of laparoscopic colorectal resection combined with simultaneous radiofrequency ablation for liver metastases.Methods Twenty-two patients with colorectal cancer and synchronous liver metastases were treated by laparoscopie colorectal resection and simultaneous radiofrequency ablation(RFA)in Third People's Hospital of Chengdu from December 2001 to July 2006.Areas of colliquative necrosis were detected by contrast-enhanced computed tomography postoperatively.The outcomes were analyzed by chi-square test.Results Of all patients,8 had muhiple liver metastases,16 had complications.Thirty-one liver metastases were treated by RFA,and no complication oecurred.The mean postoperative hospital stay was(14±5)days,and there was no perioperative death.Five of the 22 patients were identified as incomplete ablation of the tumor,and the RFA was reperformed.The recurrence of liver metastases in the RFA necrotic zone was observed in 4 patients,and RFA was reperformed on 2 of them.Six patients died,and 2 of them died of liver metastases recurrence in the RFA necrotic zone.The recurrence rate of liver metastases and mortality was 18%(4/22)and 27%(6/22),respectively.The recurrence rate of patients with the diameter of the metastatic lession≥2.0 cm was significantly higher than those with the diameter of the metastatic lession＜2.0 cm(x2=5.867,P＜0.05).Conclusions Laparoseopie colorectal resection combined with simultaneous RFA provide a curative opportunity for colorectal cancer patients who are old and have multiple liver metastases,complications,poor tolerance of operation,and for patients whose tumors are difficult to resect.
