As one of the major sources of infection, viruses could infect all organisms including bacteria, plants, animals, and humans. Infectious diseases caused by viruses pose a great threat and damage to human health and economic activities all over the world. Adaptor-associated protein kinase 1 (AAK1) is a member of the Ark1/Prk1 family of serine/threonine kinases and a specific key kinase regulating the phosphorylation of AP-2 protein μ2 subunit T156. In the past, AAK1 has been regarded as a feasible biological target for the treatment of nerve pain. Recently, scientists have found that inhibiting AAK1 can regulate endocytosis and inhibit virus invasion into cells. Therefore, AAK1 could be the potential target of anti-virus therapy. This paper reviews the research progress of small molecule AAK1 inhibitors in the field of antiviral, analyzes the future research directions and challenges, and provides new ideas for the development of antiviral drugs targeting AAK1.

3-Hydroxy-3-methylglutaryl coenzyme-A reductase (HMGR), the first enzyme of mavalonic acid pathway, is one of the key devices involved in ginsenoside biosynthesis based on synthetic biology approach. The open reading frame of a novel HMGR gene from Panax ginseng (PgHMGR2) was cloned and analyzed in this study. PgHMGR2-encoding protein showed 71.6% sequence similarity to a P. ginseng HMGR in GenBank. The full-length cDNA sequence of PgHMGR2 containing 1 770 bp, which encodes 589 amino acids, was cloned by RT-PCR strategy from P. ginseng. The bioinformatic analysis showed that PgHMGR2-encoding protein contained two transmembrane regions and the HMG_CoA_reductase domain, without signal peptide. The protein sequence of PgHMGR2 had the highest sequence similarity (99%) with Panax quinquefolius HMGR (GenBank accession No. ACV65036). The expression level of PgHMGR2 was the highest in flower based on a real-time PCR analysis, followed by leaf and root, and the lowest was in stem. The result will provide a foundation for exploring the molecular function of PgHMGR2 involved in ginsenoside biosynthesis based on synthetic biology approach in P. ginseng plants.

Purpose:Taking tuberculosis as an example, this paper aims at to analyzing the level of reimburse-ment for infectious diseases care, and clarifying the government responsibility. Methods:In order to achieve the ob-jective of this research, UHC framework was used to analyze the security level. Result:The findings of this research reveal that TB in-patients' Compensation Ratio of the New Cooperative Medical Scheme ( NCMS) was lower than aver-age level of all the NCMS patients, the out-patients' was even lower. The categories of anti-tuberculotic for free was limited, the utilization was not as expected. Medical assistance covered few people in spite of its high level of reim-bursement. Conclusion:Based on the findings of this review, it has been revealed that the medical insurance didn't make a big difference in financial protection for patients with infectious diseases. As the treatment for of infectious diseases is a quasi-public good, the government has to shoulder the responsibility of improving the compensation ratio of the patients.

Objective To discuss the impact of repeated contrast media exposure on renal function in patients who received coronary angiography ( CAG) or percutaneous coronary intervention ( PCI) within 1 week after CTA of coronary ateries. Methods A total of 258 patients who received CAG or PCI after coronary CTA were divided into the study group ( n=132, patients had CAG/PCI within 1 week after CTA) and the control group ( n=126, patients had CAG/PCI 1-2 weeks after CTA). Serum creatinine, cystatin C and estimated GFR were tested before and on day 1, 2 and 3 after procedures. The occurance of contrast-induced nephropathy ( CIN ) was recorded. Resu1ts The baseline clinical characteristics of the patients between the two groups had no significant difference. Preoperative and postoperative serum creatinine, cystatin C and eGFR values on day 1, 2 and 3 had no significant difference between the two groups (all P﹥0. 05). There was no significant difference in the incidence of CIN between two groups (5. 3% in the study group vs. 4. 8% in the control group, P﹥0. 05 ) . Conc1usions It is safe and feasible for patients with eGFR≥60 ml/( min?1. 73 m2 ) to undergo CAG or PCI within 1 week after coronary CTA.

OBJECTIVETo really realize quality control of Chinese herb purifying process, near-infrared spectroscopy (NIRS) was used not only for fast monitoring quality-control index of the process, but also for fast judgment of absorption endpoint.

METHODThe purification process of Carthamus tinctorius extracts with nonionic macroreticular resin was selected as an example. HPLC was used as the reference method to determine the content of HSYA. Quantitative and qualitative detection modes of purification were developed by NIRS combined with partial least squares (PLS) and moving block of standard deviation (MBSD).

RESULTThe correlation coefficient of the calibration model was 0.999, and the RPD for calibration and validation were above 5, of 5.54 and 5.22, respectively. Based on acquisition spectra, absorption endpoint calculated by MBSD was close to that by HPLC, Only 1 min deviation.

CONCLUSIONThe method mentioned above is proved to be convenient, rapid and nondestructive, and is applicable for fast monitoring the content of HSYA and fast judgment of absorption endpoint in purifying process of C. tinctorius extracts.

OBJECTIVETo investigate the clinical effect and safety of chiropractic in treating cervicogenic sudden hearing loss.

METHODSFrom January 2011 to October 2013, 90 patients with cervicogenic sudden hearing loss were randomly divided into treatment group and control group according to the random number table produced by SPSS 19.0 software. In the treatment group, there were 17 males and 28 females, aged from 31 to 62 years old with an average of (47.57±9.43) years; course of disease was from 1 to 3 days with an average of (1.43±0.68) days; pure-tone audiometry score was from 46.5 to 77.8 dB with the mean of (61.20±9.83) dB; Northwick Park Neck Pain Questionnaire (NPQ) score was from 17 to 31 scores with an average of (23.46±7.18) scores. In the control group, there were 15 males and 30 females, aged from 28 to 64 years old with an average of (45.77±6.99) years; course of disease was from 1 to 3 days with an average of (1.50±0.73) days; pure-tone audiometry score was from 48.1 to 75.0 dB with the mean of (63.91±8.05) dB; Northwick Park Neck Pain Questionnaire (NPQ) score was from 20 to 29 scores with an average of (25.61±10.43) scores. The patients of control group were treated with dexamethasone intravenous drip of 10 mg, 3 days later, decreased to 5 mg, 3 days again. And with the methycobal intravenous drip of 500 μg, treatment continued for 10 days. The patients of treatment group were treated with chiropractic additionally except for the therapeutic methods of control group. Chiropractic included local muscle loosening, attacking point, bilateral pulling atlanto-axial joint, and continuous treatment for 10 days. The pure-tone audiometry score and NPQ score were compared between two groups after treatment.

RESULTSAfter the treatment, pure-tone audiometry score and NPQ score in treatment group improved to (40.23± 8.14) dB and (12.70±8.29) scores respectively, which were obviously better than that of control group's (37.70±10.61) dB and (21.24±11.13) scores (P<0.05).

CONCLUSIONCompared with routine method for cervicogenic sudden hearing loss, additional chiropractic can improve hearing and relieve neck pain effectively.
