Abstract
BACKGROUND Increasing antibiotic resistance has motivated interest in non-antibiotic prophylaxis of recurrent urinary tract infections (rUTI). OBJECTIVES To conduct a systematic review of the current state of evidence of acupuncture for uncomplicated rUTI in women. SEARCH STRATEGY Nine databases (PubMed, Embase, CENTRAL, CINAHL, AMED, CBM, CNKI, CQVIP, Wanfang) were searched from inception to February 2019. SELECTION CRITERIA Randomised controlled trials (RCTs) evaluating the effects of acupuncture and related therapies for prophylaxis or treatment of uncomplicated rUTI in women were included. DATA COLLECTION AND ANALYSIS Risk of bias was assessed, and the quality and strength of evidence evaluated using the GRADE framework. Results were reported as risk ratios (RR) for dichotomous outcomes or mean differences (MD) for continuous outcomes, with 95% confidence intervals (CI). MAIN RESULTS Five RCTs involving 341 participants were included. Methodological quality of studies and strength of the evidence were low to moderate. The chance of achieving a composite cure with acupuncture therapies was greater than that with antibiotics (three studies, 170 participants, RR 1.92, 95% CI 1.31-2.81, I2 = 38%). The risk of UTI recurrence was lower with acupuncture than with no treatment (two studies, 135 participants, RR 0.39, 95% CI 0.26-0.58, I2 = 0%) and sham acupuncture (one study, 53 participants, RR 0.45, 95% CI 0.22-0.92). CONCLUSIONS Acupuncture appeared to be beneficial for treatment and prophylaxis of rUTIs, noting the limitations of the current evidence. Given the growing challenge of antibiotic resistance, there is a need for high-quality RCTs of non-pharmacological interventions such as acupuncture. TWEETABLE ABSTRACT This review found that acupuncture may improve treatment and prevent recurrence of urinary tract infection in women.

Abstract
OBJECTIVE To compare the efficacy and safety between direct anterior approach (DAA) and posterior approach (PA) in total hip arthroplasty. METHODS This study evaluated postoperative results of 92 consecutive total hip arthroplasties performed by a single surgeon; 44 from the DAA, and 48 from PA. The age, body mass index, operation time, blood loss, hospital stay, positioning of the artificial hip, postoperative Harris score and postoperative complications were recorded and analyzed. RESULTS Both the average age of the patients separately (58.0±11.9) years in DAA group and (61.0±10.4) years in PA group and the body mass index (25.1±3.7) in DAA group and (24.7±3.3) in PA group, showed no significant difference between the two groups. The DAA group had significantly reduced the hospital stay (3.8±1.7) days vs.(4.9±2.3) days for the PA group (P<0.05) and operation time was (76.0±17.4) min in DAA group, and (71.0±14.3) min in PA group (P>0.05). The amount of blood loss: in group DAA (238.0±55.3) mL, and in group PA (387.0±61.2) mL (P<0.05). There was no statistical difference in the positioning of the artificial hip: the cup anteversion in DAA group and PA group was 17.3°±5.3° vs. 18.6°± 5.1°, the cup inclination was 38.5°±5.7° vs. 37.7°±5.2°. In DAA group, there was significantly less use of assistive devices [(24.6±7.8) d vs. (31.7±10.2) d, P<0.05], and the pain was significantly lower. Harris score at the end of 6 weeks of the follow-up: in DAA group 85.7±5.4, and in PA group 81.3±6.1 (P<0.05); at the end of the last follow-up: in DAA group 93.4±4.7, and in PA group 92.3±5.3 (P>0.05). Complications were encountered in the two groups. There were two intraoperative complications (4.4%), 1 great trochanter fracture and 1 lateral cutaneous nerve injury in DAA group. No dislocation was observed in DAA group. One dislocations and 1 groin pain were recorded in PA group. No prosthesis loosening, deep vein thrombosis, sciatic nerve injury and other complications occurred in the two groups. CONCLUSION Total hip arthroplasty using the anterior approach allows for superior recovery and better stability.

Abstract
BACKGROUND AND PURPOSE The P2X7 receptor is an ATP-gated ion channel predominantly expressed in immune cells and plays a key role in inflammatory processes. Ginseng is a well-known Chinese herb with both pro- and anti-inflammatory properties and many of its actions have been ascribed to constituent ginsenosides. We screened a number of ginsenoside compounds for pharmacological activity at P2X7 receptors, that might contribute to the reported immunomodulatory actions of ginseng. EXPERIMENTAL APPROACH We used several assays to measure responses of P2X7 receptors, ATP-mediated dye uptake, intracellular calcium measurement and whole-cell patch-clamp recordings. HEK-293 cells stably expressing human P2X7 receptors were used in addition to mouse macrophages endogenously expressing P2X7 receptors. KEY RESULTS Four ginsenosides of the protopanaxdiol series, Rb1, Rh2, Rd and the metabolite compound K (CK) potentiated the dye uptake responses of P2X7 receptors, whereas other ginsenosides tested were ineffective (1-10 μM). The potentiation was rapid in onset, required a threshold concentration of ATP (>50 μM) and had an EC50 of 1.08 μM. CK markedly enhanced ATP-activated P2X7 currents, probably via an extracellular site of action. One of the consequences of this potentiation effect is a sustained rise in intracellular Ca(2+) that could account for the decrease in cell viability in mouse macrophages after a combination of 500 μM ATP and 10 μM CK that are non-toxic when applied alone. CONCLUSIONS AND IMPLICATIONS This study identifies selected ginsenosides as novel potent allosteric modulators of P2X7 channels that may account for some of the reported immune modulatory actions of protopanaxdiol ginsenosides in vivo.

Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) is a major global health burden and will become the third largest cause of death in the world by 2030. It is currently believed that an exaggerated inflammatory response to inhaled irritants, in particular cigarette smoke, cause progressive airflow limitation. This inflammation, where macrophages, neutrophils and lymphocytes are prominent, leads to oxidative stress, emphysema, airways fibrosis and mucus hypersecretion. COPD responds poorly to current anti-inflammatory treatments including corticosteroids, which produce little or no benefit. Panax ginseng has a long history of use in Chinese medicine for respiratory conditions, including asthma and COPD. OBJECTIVES In this perspective we consider the therapeutic potential of Panax ginseng for the treatment of COPD. RESULTS Panax ginseng and its compounds, ginsenosides, have reported effects through multiple mechanisms but primarily have anti-inflammatory and anti-oxidative effects. Ginsenosides are functional ligands of glucocorticoid receptors and appear to inhibit kinase phosphorylation including MAPK and ERK1/2, NF-κB transcription factor induction/translocation, and DNA binding. They also inhibit pro-inflammatory mediators, TNF-α, IL-6, IL-8, ROS, and proteases such as MMP-9. Panax ginseng protects against oxidative stress by increasing anti-oxidative enzymes and reducing the production of oxidants. CONCLUSION Given that Panax ginseng and ginsenosides appear to inhibit processes related to COPD pathogenesis, they represent an attractive therapeutic target for the treatment of COPD.

Abstract
Here, we aimed to clone and identify the GmIMT1 gene related to the salt stress response in soybean. The full-length cDNA sequence of the GmIMT1 gene was amplified in soybean using degenerate primers of Mesembrythmum crystallium. To understand the stress response, the GmIMT1 gene was cloned and sequenced. Then, the expression vectors of the gene were constructed, and introduced into the model plant Arabidopsis thaliana through Agrobacterium mediated transformation, and the salt tolerance was analyzed in the transgenic plants. In addition, the expression patterns of GmIMT1 gene in soybean were analyzed. The expression was examined in different organs (roots, leaves, flower seeds, and stem) and under different stress conditions (drought, high salt, low temperature, salicylic acid, ethane, abscisic acid, and methyl jasmonate) by real-time fluorescent quantitative polymerase chain reaction analysis. The results showed that the root, leaves, and stems exhibited high level of GmIMT1 gene expression, whereas there was no expression in the seeds. In addition, the GmIMT1 gene expression was upregulated under all stress conditions. Overall, the results clearly indicate that GmIMT1 might be involved in multiple plant response pathways to the different environmental conditions. Furthermore transgenic plants exhibited higher salt-tolerance compared to wild type plants.

Abstract
Tanshinone IIA (TSA) is a major constituent of Salvia miltiorrhiza Bunge widely used in the treatment of stroke. This current study aimed to investigate the nature of brain penetration of TSA using several in vitro and in vivo models. The uptake and efflux of TSA in primary rat brain microvascular endothelial cells (RBMVECs) were altered in the presence of a PgP inhibitor or multidrug-resistance-associated protein (Mrp1/2) inhibitor. A polarized transport of TSA was found in RBMVEC monolayers with facilitated efflux from the abluminal to the luminal side. The polarized transport of TSA was attenuated by PgP or Mrp1/2 inhibitors. In an in situ rat brain perfusion model, TSA crossed the blood-brain barrier at a greater rate than that for sucrose, and the brain penetration was increased in the presence of a PgP or Mrp1/2 inhibitor. The brain levels of TSA were only about 31% of that in the plasma and it increased to 74-77% of plasma levels when verapamil or quinidine was coadministered in rats. The entry of TSA to the central nervous system (CNS) significantly increased in rats subjected to middle cerebral artery occlusion or treatment with quinolinic acid. The normalized brain penetration of TSA in mdr1a((-/-)) mice was much higher than the wild-type mice. Taken collectively, these findings provide evidence that TSA has limited brain penetration through the blood-brain barrier owing to the contribution of PgP and possibly Mrp1/2.
