The purpose of this study was to ascertain the usefullness of four mental health measures in their application to Chinese elderly subjects. These measures which included CES—D, GHQ—30, LSI, and MST were adapted to assess general symptoms of depression and minor psychiatic disorder, life satisfaction, and mental state of the elderly people. Results of these findings indicated that split—half and test—retest reliabilities of these measures were highly satisfactory. With respect to validity, test performace of a group of psychiatric patients (N=31) and normal elderly subjects (N=30) were found to be significantly differencetiated. Furthermore, the pattern of scores obtained by the psychiatric patients also matched well with the clinical diagnosis made by a consultant. Normative data in an old—old sample (N=554) revealed mild to moderate correlations between measures, reflecting favourably on their convergent validity. Significant sex differences were found, which necessitated the establishment of separate norms for males and females subjects.

OBJECTIVEIt laid the foundation of the large sample data mining for a comprehensive summary concerning four properties theory of traditional Chinese medicine (TCM), and also provided theory clues on determination of four properties for the new resource development of TCM and the clinical use of Chinese medicine.

METHODFour properties data of 8 980 Chinese medicines from "Chinese herbal medicine (CHM)" and associated function index data were chose as data sets. Then, the IBM SPSS Clementine 14.1 data mining platform and Apriori model were adopted to mining classification-association rules, setting the minimum support threshold of rule antecedent and the minimum confidence threshold as 0.5% and 60%.

RESULT11 classification-association rules involved in warm, cold and mild natures were found.

CONCLUSIONIt was discovered that the TCM with functions of "dispelling wind-cold, warming the middle, stopping pain and expelling wind-removing dampness, tonifying kidney yang, unblocking meridians and expelling wind-removing dampness, dispelling cold to stop pain, strengthening sinews-bones and expelling wind-removing dampness" was likely warm-natured, with functions of "tonifying the lung" was likely mild-natured, and with functions of " clearing heat and drying dampness, clearing heat and purging fire, eliminating restlessness" was likely cold-natured.

AIM:To explore relationship between the normal strehl ratio ( SR ) values of total aberrations/SR values of total higher-order aberrations and modulation transfer function ( MTF ) at total corneal at different pupil diameters in normal population.
METHODS: To exam the SR values of total aberrations and SR values of total higher-order aberrations of total corneals in 200 people ( 400 eyes ) using SIRIUS 3D topography system and analysis the corresponding root-mean-square ( RMS) .
RESULTS: The subjects with different pupil diameters (3. 0, 5. 0, 6. 0, 7. 0mm)'s exam results of total corneal were as following:SR value of total aberrations 100’(0. 45±0. 12), (0. 25±0. 06), (0. 17±0. 05), (0. 13±0. 04); SR value of total higher order ab cerrations 100’(0. 69±0. 14), (0. 34±0. 07), (0. 24±0. 05), (0. 16±0. 04);SR value of total aberrations 200’(0. 45±0. 12), (0. 24±0. 06), (0. 20±0. 04), (0. 16±0. 03); SR value of total higher order aberrations 200’(0.70±0. 13), (0. 35±0. 07), (0. 27±0. 06), (0. 20±0.04 ) . The SR values of each group decreases with the increases of pupil diameters. The SR values of total aberrations and SR values of total higher - order aberrations at total corneals are negatively correlated with corresponding RMS value. When the pupil diameter is small, the SR value of total aberrations is more related to higher frequency region of MTF. When the pupil diameter is big, the SR value of total aberrations is more related to lower frequency region of MTF.
CONCLUSION: The visual performance of normal people can be well reflected by SR values of total aberrations and SR values of total higher - order aberrations at total corneal.

This study aimed to explore the outcomes of progestin-primed ovarian stimulation protocol (PPOS) in aged infertile women who failed to get pregnant in the first IVF/ICSI-ET cycles with GnRH-a long protocol.A self-controlled study was conducted to retrospectively investigate the clinical outcomes of 104 aged infertile patients who didn't get pregnant in the first IVF/ICSI-ET treatment by stimulating with GnRH-a long protocol (non-PPOS group),and underwent PPOS protocol (PPOS group) in the second cycle between January 2016 and December 2016 in the Center for Reproductive Medicine,Renmin Hospital of Wuhan University.The primary outcomes included clinical pregnancy rate of frozen-thawed embryos transfer (FET) in PPOS group,and good-quality embryo rate in both groups.The secondary outcomes were fertilization rate,egg utilization rate and cycle cancellation rate.The results showed that there were no significant differences in basal follicle stimulating hormone (bFSH),antral follicle count (AFC),duration and total dosage of gonadotropin (Gn),number of oocytes retrieved,intracytoplasmic sperm injection (ICSI) rate,fertilization rate,and cycle cancellation rate between the two groups (P＞0.05).However,the oocyte utilization rate and good-quality embryo rate in PPOS group were significantly higher than those in non-PPOS group (P＜0.05).By the end of April 2017,62 FET cycles were conducted in PPOS group.The clinical pregnancy rate and embryo implantation rate were 22.58％ and 12.70％,respectively.In conclusion,PPOS protocol may provide better clinical outcomes by improving the oocyte utilization rate and good-quality embryo rate for aged infertile patients who failed to get pregnant in the first IVF/ICSI-ET cycles.

OBJECTIVETo construct the acid-sensitive potassium hannel-3(TASK3) eukaryotic expression plasmid and to establish a stable SH-SY5Y cell line expressing enhanced green fluorescent protein (EGFP)-tagged TASK3.

METHODSTASK3 coding region was subcloned into pEGFP-N1 plasmid to construct a recombinant vector alled pEGFP-TASK3. The correct recombinant expressing plasmid was transfected with X-feet transfection reagent to SH-SY5Y cells. The cell line stably expressiing EGFP tagged-TASK3 gene was established by screening with antibiotic G418 and fluorescence microscope. The expression and localization of the EGFP tagged-TASK3 fusion protein was detected by Western blot and confocal microscope. Exposure of the SH-SY5Y cell line expressing stably TASK3-eGFP fusion proteins was exposed to different pH media (7.0, 6.7, 6.4, 6.1) for 24 h, the cell viability was assessed with cell counting Kit-8 (CCK-8).

RESULTSAll the results of identification by PCR, digestion with restriction endonuclease and sequencing indicated that the recombinant eukaryotic expression plasmid pEGFP-TASK3 was constructed correctly. The stable SH-SY5Y cell line expressing EGFP tagged-TASK3 fusion protein was successfully established. Exposure of the wild type SH-SY5Y cells and the stable SH-SY5Y-GFP tag-TASK3 cell line to different pH media (7.0, 6.7, 6.4, 6.1) for 24 h, the cell viability of two group cells significantly reduced with pH declining, and the difference was statistically significant (P < 0.05). Compared with wild type SH-SY5Y cells, the cell viability of stable SH-SYSY-GFP tag-TASK3 cell line increased significantly with the same pH media, and the difference was statistically significant (P < 0.05).

CONCLUSIONThe eukaryotic expression vector pEGFP-TASK3 is successfully constructed and the cell line stably expressing TASK3-eGFP fusion is established which is important for their fundamental research and potential applications.

Inosine 5′-monophosphate dehydrogenase (IMPDH) is a key enzyme catalyzing the rate-limiting step of de novo nucleotide synthesis in vivo. In recent years, it has become a therapeutic target for anti-virus, anti-bacterial, anti-cancer, anti-parasitic and other diseases. IMPDH inhibitors have been shown to inhibit viral prolife-ration in host cells by depleting guanosine 5′-monophosphate (GMP), the raw material required for viral replication in host cells, with broad-spectrum antiviral properties. In order to find novel anti-coronavirus drugs, this study screened 22 potential IMPDH inhibitors from 70 000 natural small molecule libraries based on IMPDH protein structure using molecular docking and ROC calculation for virtual screening. With ribavirin as the positive control drug, Huh7 cell and H460 cell models were used to verify the anti-coronavirus HCoV-229E and HCoV-OC43 activities of 22 selected target compounds. Among them, compounds 11, 12, 15 and 16 showed inhibitory activity against coronavirus HCoV-229E. The compounds 4, 12, 13 and 15 showed inhibitory activities against coronavirus HCoV-OC43. 12 and 15 showed significant inhibitory activity against both two coronaviruses, and their efficacy was similar to ribavirin at the same dose, which can be further studied as a lead compound for IMPDH inhibitors.
