The paper summarizes the clinical experience of professor ZHANG Ren in the staging treatment with characteristic acupuncture techniques for oculomotor paralysis. According to the symptoms of oculomotor paralysis, the staging treatment is given, in which acupuncture is dominant and the needling techniques are optioned in compliance with the symptoms. In the early, middle and late stages of illness, three different acupuncture therapies are delivered accordingly, i.e. the combination of the point-toward-point needling at the four acupoints located on the forehead and the electroacupuncture with disperse-dense wave, the surrounding needling and the triple needling at the acupoints around the eyeball, as well as the perpendicular needle insertion at the three acupoints within the orbit. Professor ZHANG Ren lays the stress on identifying the etiology and differentiating the symptoms, as well as the early intervention for the disease. For the intractable cases, the comprehensive regimen such as acupoint injection, dermal needling and auricular point sticking is supplemented. During treatment, the spirit harmonization is greatly considered to ensure the effectiveness. On the basis of the staging acupuncture therapy, the acupuncture technique for harmonizing the spirit and regulating qi is combined to obtain the favorable clinical effect on oculomotor paralysis.

[Professor ZHANG Ren's experience of stage treatment for refractory facial paralysis].

To introduce professor ZHANG Ren's experience that different stages of refractory facial paralysis should be treated with different acupuncture methods.In early stage of facial paralysis,identifcation is important. Electroacupuncture is applied to connect Qianzheng (Extra) with Cuanzhu (BL 2), Sibai (ST 2) and Jiachengjiang (Extra), by observing the twitches of facial muscles, it is determined whether it is easy to develop into refractory facial paralysis, in order to actively take preventive treatment. In the recovery stage of refractory facial paralysis, comprehensive therapy including acupuncture, acupoint injection, quick cupping and auricular point pressure are adopted, and penetration needling is applied at three points of mouth, three points of cheek and three points of forehead.In the sequelae stage of refractory facial paralysis，on the basis of comprehensive therapy, targeted treatment is adopted according to different sequelae.

Discovery of Influenza Polymerase PA-PB1 Interaction Inhibitors Using an In Vitro Split-Luciferase Complementation-Based Assay.

The limited therapeutic options and increasing drug-resistance call for next-generation influenza antivirals. Due to the essential function in viral replication and high sequence conservation among influenza viruses, influenza polymerase PA-PB1 protein-protein interaction becomes an attractive drug target. Here, we developed an in vitro split luciferase complementation-based assay to speed up screening of PA-PB1 interaction inhibitors. By screening 10,000 compounds, we identified two PA-PB1 interaction inhibitors, R160792 and R151785, with potent and broad-spectrum antiviral activity against a panel of influenza A and B viruses, including amantadine-, oseltamivir-, or dual resistant strains. Further mechanistic study reveals that R151785 inhibits PA nuclear localization, reduces the levels of viral RNAs and proteins, and inhibits viral replication at the intermediate stage, all of which are in line with its antiviral mechanism of action. Overall, we developed a robust high throughput-screening assay for screening broad-spectrum influenza antivirals targeting PA-PB1 interaction and identified R151785 as a promising antiviral drug candidate.

Systematic Review of Adverse Effects: A Further Step towards Modernization of Acupuncture in China.

As a further step towards the modernization of acupuncture, the objective of this review was to figure out the frequency and severity of adverse complications and events in acupuncture treatment reported from 1980 to 2013 in China. All first-hand case reports of acupuncture-related complications and adverse events that could be identified in the scientific literature were reviewed and classified according to the type of complication and adverse event, circumstance of the event, and long-term patient outcome. The selected case reports were published between 1980 and 2013 in 3 databases. Relevant papers were collected and analyzed by 2 reviewers. Over the 33 years, 182 incidents were identified in 133 relevant papers. Internal organ, tissue, or nerve injury is the main complications of acupuncture especially for pneumothorax and central nervous system injury. Adverse effects also included syncope, infections, hemorrhage, allergy, burn, aphonia, hysteria, cough, thirst, fever, somnolence, and broken needles. Qualifying training of acupuncturists should be systemized and the clinical acupuncture operations should be standardized in order to effectively prevent the occurrence of acupuncture accidents, enhance the influence of acupuncture, and further popularize acupuncture to the rest of the world.

Identification of Chemical Compounds That Inhibit the Function of Glutamyl-tRNA Synthetase from Pseudomonas aeruginosa.

Pseudomonas aeruginosa glutamyl-tRNA synthetase (GluRS) was overexpressed in Escherichia coli. Sequence analysis indicated that P. aeruginosa GluRS is a discriminating GluRS and, similar to other GluRS proteins, requires the presence of tRNA(Glu) to produce a glutamyl-AMP intermediate. Kinetic parameters for interaction with tRNA were determined and the k(cat) and KM were 0.8 s(-1) and 0.68 µM, respectively, resulting in a k(cat)/KM of 1.18 s(-1) µM(-1). A robust aminoacylation-based scintillation proximity assay (SPA) assay was developed and 800 natural products and 890 synthetic compounds were screened for inhibitory activity against P. aeruginosa GluRS. Fourteen compounds with inhibitory activity were identified. IC50s were in the low micromolar range. The minimum inhibitory concentration (MIC) was determined for each of the compounds against a panel of pathogenic bacteria. Two compounds, BT_03F04 and BT_04B09, inhibited GluRS with IC50s of 21.9 and 24.9 µM, respectively, and both exhibited promising MICs against Gram-positive bacteria. Time-kill studies indicated that one compound was bactericidal and one was bacteriostatic against Gram-positive bacteria. BT_03F04 was found to be noncompetitive with both ATP and glutamic acid, and BT_04B09 was competitive with glutamic acid but noncompetitive with ATP. The compounds were not observed to be toxic to mammalian cells in MTT assays.
