Young faculty are an essential part of a university's strength and is important for its sustainable development.And their scientific research capability is associated with the long-term development of the university.At present,there are 4 major problems with the development of young faculty's research capabilities,which include their relatively single academic knowledge structure,insufficient experience in writing proposals,insufficient opportunities for academic exchange,and inequity in resource allocation.Establishing a training mechanism may help solve some of the problems and promot their development.The research management department of a university must abandon erroneous traditional management concepts,provide research training seminars,develop a new mechanism to stimulate academic exchange,design a system for short-term laboratory rotations,and promote the participation of your faculty in major research projects.These may bring about marked improvement in the improvement of young faculty's research capabilities.

OBJECTIVETo observe the efficacy of ultrasonic conductometric acupoint penetration of Wenhua Zhitong Recipe (WZR) in treating adenomyosis.

METHODSTotally 40 adenomyosis patients with Shen-deficiency blood stasis syndrome were randomly assigned to the treatment group and the control group, 20 in each group. Patients in the treatment group received ultrasonic conductometric acupoint penetration of WZR from the 2nd day before menstruation to the end of menstruation, while those in the control group took WZR. All patients received 3 consecutive menstrual cycles. Endometrial contents of cyclooxygenase-2 (COX-2) and oxytocin receptor (OTR) were determined using SP immunohistochemical staining method before and after treatment. Clinical effect, efficacy of Chinese medical syndrome, changes of uterus volume, and contents of carbohydrate antigen 125 (CA125) were observed before and after treatment.

RESULTSThere was no statistical difference in the total clinical effect between the two groups (P = 0.357). Efficacies for relieving abdominal pain and lumbar soreness during menstruation were better in the treatment group than in the control group (P < 0.05). Uterus volume, endometrial levels and integrals of COX-2 and OTR decreased in the two groups after treatment (P < 0.05, P < 0.01).

CONCLUSIONUltrasonic conductometric acupoint penetration of WZR and oral administration of WZR both could effectively improve adenomyosis patients' symptoms such as Shen deficiency, and blood stasis, reduce the foci of uterus, and relieve the pain.

Background Nerve growth factor (NGF) plays an important role in the maintenance of the tear film stability.It is well known that the damage of ocular surface causes dry eye in the patients with thyroid-associated ophthalmopathy (TAO).However,if NGF is helpful for the stability of tear film is unclear.Objective This study was to investigate the relationship of NGF concentration in tear with tear film stability in TAO patient before and after glucocorticoid treatment.Methods Prospective observational cohort study was designed.This study was approved by the Ethic Committee of Binzhou Medical College,and written informed consent was obtained from each subject before entering this trial.Thirty-eight patients with active TAO and thirty age-and gender-matched controls were enrolled in the study.Prednisolone acetate tablets were administered in TAO patients for 4 weeks at a back-titration regimen.The tear fluid was collected and NGF level was detected by ELISA.Clinical activity score (CAS) was evaluated under the slit lamp lamp.Schirmer Ⅰ test (S Ⅰ t) was performed and breakup time of tear film (BUT) was obtained in controls and patients with active TAO before and 4 weeks after steroid treatment.Results Baseline NGF levels in tear was higher in the patients with active TAO than in the controls (U=-5.026,P＜0.01).NGF level decreased from 46.23 (42.34,51.42) ng/L to 27.45 (19.38,29.12) ng/L 4 weeks after steroid treatment (Z=-6.172,P＜0.05),and CASdecreased significantly from 6 (5,7) to4 (2,5) (Z=-2.496,P＜0.01).SⅠtvalue increased from 6 (4,11) mm to 11 (7,16) mm 4 weeks after steroid treatment (Z =-4.286,P＜0.05),and the BUT prolonged from 5 (3,9) seconds to 11 (6,14) seconds(Z=-3.160,P＜0.05).NGF levels in active TAO was significantly correlated with CAS (r=0.645,P＜0.01),S Ⅰ t value (r =-0.530,P＜0.01) and BUT (r =-0.430,P＜0.01).Conclusions Tear NGF may stabilized the tear film.The application of steroid anti-inflammation drug can reduce the tear NGF level,increase the tear secretion and improve the tear film stability in patients with active TAO.

To study the effects of the extract of fungal elicitor, AgNO3, MeJA and yeast on the growth and content of secondary metabolites of adventitious roots in Tripterygium wilfordii. The above elicitors were supplemented to the medium, the growth and the content of secondary metabolites were measured. When the medium was supplemented with the elicitor Glomerella cingulata or Collectotrichum gloeosporioides, the content of triptolide was increased by 2.24 and 1.93-fold, the alkaloids content was increased by 2.02 and 2.07-fold, respectively. The optimal concentration of G. cingulata was 50 μg/mL for accumulation of triptolide, alkaloids and for the growth of adventitious roots. AgNO3 inhibited the growth of adventitious roots and the accumulation of the alkaloids, whereas it (at 25 μmol/L) increased the accumulation of triptolide by 1.71-fold compared to the control. The growth of adventitious roots, the contents of triptolide and alkaloids were increased 1.04, 1.64 and 2.12-folds, respectively when MeJA was at 50 μmol/L. When the concentration of yeast reached 2 g/L, the content of triptolide increased 1.48-folds. This research demonstrated that supplementation of AgNO3 and yeast enhanced the biosynthesis of triptolide in adventitious roots and the synergism of G. cingulata and MeJA could promote the biosynthesis of both triptolide and alkaloids.

Objectives To observe the effects of levetiracetam (LEV) on spatial learning and memory ability in epileptic rats and the expression of synaptophysin (SYN) and growth-associated protein 43 (GAP-43) in the hippocampus of rats with epi-lepsy induced by lithium pilocarpine (Li-pilo). Methods SD rats were randomly divided into normal control group (normal saline group), LEV group (treatment group), Li-pilo group (model group) and LEV control group (normal dose group). Twenty-four hours after the establishment of model, LEV (150 mg/kg per day) was given to rats in LEV group and LEV control group, and equivalent normal saline was given to rats in normal control group and Li-pilo group. At 7, 14 and 28 days after successful model building, the expression levels of the SYN and GAP-43mRNA in hippocampus of rats in each group were detected by RT-PCR. In the 4th week, the ability of learning and memory of rats in each group was evaluated by the Morris water maze. Results There was no significant difference in escape latency and the frequency of crossing platform between LEV control group and normal control group in Morris water maze test. Compared with normal control group, the rats in Li-pilo group had a longer latency to escape and reduced frequency of crossing platform (P<0.05). Compared with Li-pilo group, the rats in LEV group had shorter latency to escape and more frequency of crossing platform (P<0.05). There was no significant difference in the expressions of SYN and GAP-43mRNA in hippocampus of rats between LEV control group and normal control group. The expressions of SYN and GAP-43mRNA in Li-pilo group were lower than those of normal control group and LEV group (P<0.05). Conclusions Levetiracetam may improve learning and memory ability of rats with epilepsy through the regulation of SYN and GAP-43mRNA expressions in hippocampal tissue.
