BACKGROUND:How to preserve the fertility and ovarian function in patients with procreation needs has important significance and broad application prospects. OBJECTIVE:To summarize the recent studies about ovarian tissue cryopreservation, preservation and evaluation methods, and to explore the best solution for ovarian tissue freezing. METHODS:An online computer-based retrieval of PubMed database and Wanfang database between January 1994 and January 2014 was performed by the first author. The key words were ovarian tissue, ovarian tissue cryopreservation, freezing factors in English and Chinese. Final y 59 literatures on the ovarian tissue cryopreservation technique, influencing factor of cryopreservation, resuscitation, and human ovarian tissue transplantation were included. RESULTS AND CONCLUSION:Currently, laboratory methods of ovarian tissue cryopreservation are divided into slow-rate freezing, ultra-rapid cooling and vitrification technology. The freezing effect may vary in different patients, tissue sections, cryoprotectants species, penetration time and frozen carrier. After the recovery, the histological morphology of granulosa cells and fol icles was observed. The fol icles were counted to evaluate ovarian tissue. Freeze-thaw effects were evaluated by observing the changes of subcellular structures. The apoptotic signals were also detected. Immunohistochemical analysis was applied to detect the proliferation after recovery and apoptosis-related information. Variation in the in vitro culture reflected endocrine levels. Genetic level detection was also performed. In recent years, frozen ovarian tissue is clinical y applied for the transplantation, to restore reproductive endocrine function of the patients, or get mature germ cells, thereby preserving female fertility. However, there are stil some questions about cryopreservation of ovarian tissue, which need further study.

Objective To examine the curative effect of EEG biofeedback therapy on children with attention deficit hyperactivity disorder (ADHD),and to investigate the neural mechanism underlying the executive function in children with ADHD.Methods 42 children with ADHD participated a Go/Nogo task before and after the EEG biofeedback therapy which was consisted of 20 times of treatments.The curative effect was evaluated using the behavioral and electrophysiological indexes associated with the Go/Nogo processing in the experiment.Results Commission error significantly decreased after the therapy ( (2.95 ±2.22 ) vs (4.65 ±4.47),P＜0.05 ).Latencies of P2 ( (210.00 ± 27.54) ms vs ( 228.27 ± 34.17 ) ms) and N2 components ( ( 310.59 ± 45.82) ms vs (328.00 ± 42.27)ms) elicited by Go trials significantly exhibited shorter at the end of therapy.Additionally,the amplitude of N2 component elicited by Nogo trials exhibited significantly decreased after therapy ((0.23 ±3.79)μV vs (-1.84 ± 4.23 ) μV,P ＜ 0.05).Conclusion The EEG biofeedback therapy is effective in debasing the hyperactivity/impulsive behaviors and improving the ability of target detection,which may be beneficial to the attention ability and conflict detecting in children with ADHD.EEG biofeedback is an effective treatment to ADHD.

OBJECTIVE:To analyze the problems about the prescription review by the monitoring system for rational drug use (PASS 1.6.1.7) and discuss the countermeasures. METHODS:A retrospective method was adopted. A total of 4 942 prescriptions of our hospital in the first quarter of 2015 were selected at random,and reviewed by PASS and the pharmacist respectively. The re-view results were analyzed,and then countermeasures were put forward for the problems found to exist in the software review. RE-SULTS & CONCLUSIONS:The conformity rates of prescriptions which had been determined as acceptable through PASS review and pharmacist review were 81.20% and 97.40% respectively. PASS misjudged 929 (18.80%) rational prescriptions as irrational ones,mainly concerning administration and dosage,simultaneous existence of Western medicine and Chinese patent medicine on one prescription,repeated drug use and use with caution,etc. PASS misjudged 122(2.47%)irrational prescriptions as rational pre-scriptions,mainly concerning administration and dosage,inconformity between diagnosis and drug use,etc. The above-said prob-lem was attributed to imperfect hospital management and insufficient software intelligence. It is suggested that the hospital should strengthen the data maintenance and management of information system and PASS developer should improve software rules to in-crease the accuracy rate of prescription review.

OBJECTIVE:To provide reference for the rational use of haemocoagulase hemostatic drugs in the clinic by under-standing the perioperative utilization. METHODS:In retrospective study,1 200 discharge records of perioperative prophylactic ap-plication of haemocoagulase hemostatic drugs were collected randomly during Jan.-Dec. 2014.,and then analyzed statistically in re-spects of consumption sum and amount,application,irrational drug use,etc. The cost of hemocoagulase accounted for 7.39% of total drug cost,among which Haemocoagulase agkistrodon for injection had the highest consumption amount and sum,with utiliza-tion ratio of 51.44%. Average medication time of hemocoagulase during perioperative period was 2.36d;maximal average cost of hemocoagulase was 684.52 yuan in ENT and head and neck surgery department/ stomatology department;ENT and head and neck surgery department/ stomatology department,urinary surgery department had long average medication time,being 3.85d and 3.50d. RESULTS:Only 39.42% haemocoagulase hemostatic drugs were reasonably used during perioperative period. The unreasonable manifestation included:improper medication time(52.15%), too long medication course after operation(35.75%),wrong usage (5.61%)and replacing various haemocoagulase hemostatic drugs without reason(5.06%). CONCLUSIONS:The striking phenome-non of irrational use of haemocoagulase hemostatic drugs during perioperative period is severely worrying,so we need to strength-en the standard management and pharmaceutical supervision and intervention by clinical pharmacists.

AIM To study the effects of ?-opioid receptor activation on the cardiac hypertrophy, cultured cardiomyocytes were to used study the inhibitory effects of U58,488H on cellular volume and norepinephrine(NE)-induced hypertrophy in the presence or absence of norbinaltorphimine(nor-BNI). METHODS The protein content was assayed with Lowry's method. The cardiomyocytes'volumes was measured by an eyepiece graticule of inverted microscope. The contracting frequency of cultured myocytes was counted by the inverted microscope. RESULTS A ?-opioid receptor agonist U50,488H at (0.1～10 ?mol?L -1 ) inhibited the protein content of cultured myocardial cells in normal serum medium in a dose-dependent manner. The inhibitory effects of U50,488H were completely blocked by pretreatment with nor-BNI, a specific ?-opioid receptor antagonist at 1 ?mol?L -1 . U50,488H (0.1～10 ?mol?L -1 ) also inhibited NE-induced cellular hypertrophy in low serum medium, which also were abolished by nor-BNI(1 ?mol?L -1 ). CONCLUSIONS U50,488H inhibited NE-induced hypertrophy. The inhibitory effects of U50,488H are involved in mediating the action of NE-induced cardiac hypertrophy.
