1.GABAA Receptors in Neuropsychiatric Disorders and Its Therapeutic Potential
World Science and Technology-Modernization of Traditional Chinese Medicine 2014;(10):2236-2241
Abundant evidences indicate a role of GABAergic system in the pathogenesis of neuropsychiatric dis-orders. GABAA receptors modulators have been long used in clinical. But the unwanted side-effect and risk of drug dependence have limited their use. With the increase understanding of the role of individual GABAA recep-tor subtypes in the pathology of these diseases, the subtype-selective GABAA receptors modulators and the multi-compound therapy may serve as potential therapeutic strategies. Here we review the researches which revealed the involvement of GABAA receptors in anxiety, depression and schizophrenia, and the research for new development in subtype-selective GABAA receptor modulators.

4. Simultaneous determination of six components in Baikening Granules by UPLC-MS/MS
Chinese Traditional and Herbal Drugs 2016;47(1):76-80
Objective: To develop an ultra-high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method for simultaneous determination of six components (indirubin, peimine, peiminine, ginkalide A, ginkalide B, and ginkalide C) in Baikening Granules. Methods: Preparing the samples solution by Soxhlet's extraction using methanol-chloroform as solvent, and multiple reaction monitoring (MRM) with a polarity-switching electrospray ionization (ESI) source between positive and negative modes was used for the quantification of indirubin, two peimisines, and three bilobalides. The detection was performed on an Inertsutain C18 column (75 mm × 3.0 mm, 2 μm) using a mobile phase consisted of methanol-acetonitrile and 2 mmol/L ammonium acetate water solution with gradient elution lasting 6 min. Results: All of the analytes showed good linearity (r ≥ 0.995 8) in the tested ranges. The precision, repeatability, and stability of the method were good for the six components. The average recoveries were in the range of 96.5%-105.1% with relative standard deviations (RSD) ≤ 4.2%. Conclusion: The new established polarity-switching LC-MS-MS method has been proven to be highly sensitive and effective in evaluating the quality of Baikening Granules, and peimine, peiminine, ginkalide A, ginkalide B, and ginkalide C are quantified in this drug for the first time.

Aldose reductase ( AR ) belonging to nicotinamide-adenine dinucleotide phosphate ( NADPH ) -dependent aldehyde-keto reductase superfamily, is the key rate-limiting enzyme in the polyol pathway which plays an important role in the body’s high-sugar metabolism. AR is widely present in the kidneys, blood vessels, lens, retina, heart, skeletal muscle and other tissues and organs, converts glucose to sorbitol which easy permeability of cell membranes, cause cell swelling, degeneration, necrosis, and have a close relationship with the development of chronic complications of diabetes mellitus. Diabetic retinopathy ( DR ) is a multifactorial disease, the exact cause is currently unknown, but polyol pathway has been demonstrated to play an important role in the pathogenesis of DR. Clinical risk factors such as blood sugar control, blood pressure and other treatments for DR only play a part effect of remission or invalid, if we can find out DR genes associated with the disease, this will contribute to a better understanding of the pathological mechanisms and contribute to the development of new treatments and drugs. The current research progress of AR, AR gene polymorphism, Aldose reductase inhibitors to DR was reviewed in this article.

Objective To evaluate the effect of Alprostsdil combined with Magnesium Isoglycyrrhizinate on hepatocirrhosis at active phase. Method 74 inpatients collected from our hospital were randomly divided into control group(37 cases)and treatment group(37 cases). The patients in control group were given conventional liver protecting treatment. In addition to routine therapy of the control group, the patients in treatment group received intravenous Alprostadil and Magnesium Isoglycyrrhizinate injection once a day for 4 weeks. Results The total effective rate of treatment group was 67. 6%, and that of control group was 40. 5%, and the difference was significant (P < 0. 05).Conclusion Alprostadil combined with Magnesium Isoglycyrrhizinate has good clinical therapeutic effect on hepatocirrhosis at active phase.

Objective To evaluate the effectiveness of discharge planning in patients after total laryngectomy. Methods One hundred and four patients were randomly divided into the intervention group and the control group, there were 52 cases in each group. The patients in the control group were received routine nursing, while the patients in the intervention group were received discharge planning based on routine nursing. The patients'days of hospitalization, scores of the Exercise of Self-care Agency Scale (ESCA) at discharge and 4 weeks after discharge, scores of University of Washington Quality of Life Questionnaire (UW-QOL) at 4 weeks after discharge and re-admission rate were compared between the two groups. Results The ESCA scores in the intervention group at discharge (108.62 ± 11.23) and 4 weeks after discharge (116.35 ± 12.08) were significantly higher than those of the control group at discharge (96.16±10.34) and 4 weeks after discharge (105.20±10.76) respectively (t=5.886, 4.970, P<0.05), and the UW-QOL score in the intervention group (810.56±98.25) was significantly higher than that of the control group (687.32±96.74) at 4 weeks after discharge (t=6.445, P<0.05). No significant difference in the days of hospitalization was found between the intervention group (15.27 ± 3.33) and the control group (16.60 ± 3.97) (P>0.05). The re-admission rate in the intervention group (2/52,3.85%) was significantly lower than that of the control group (8/52,15.38%) (χ2=3.983, P<0.05). Conclusions Discharge planning can improve the ability of self-care and quality of life in patients after total laryngectomy, and reduce the re-admission to hospital.
