Ralstonia metallidurans CH34 was isolated from the deposit of a znic factory .The degradation of phenol by R .metallidurans CH34 was investigated. The results showed that R . metallidurans CH34 possesses high ability to degrade phenol with the biodegradation rate constant of 0.33 . The optimal pH , temperature and volume of medium for phenol degradation are pH 7.0 , 30℃ , and 20%(v/v), respectively . In addition , this strain retains its ability to degrade phenol in the presence of high concentration of heavy metal ion .The sodium citrate , sodium succinate can enhance the degradation of phenol.

AIM: To evaluate the efficacy of combined therapy for amblyopia in children by making use of pattern visual evoked potential ( P-VEP) game.
METHODS: This was a prospective case control study. These asthenopic children were divided into two groups. The control group ( 66 eyes of 49 patients ): occlusive therapy with glasses, cover, precision work, red light treatment and so on, later the stereo vision training was added. The experimental group (72 eyes of 52 patients):conventional methods mentioned above with P - VEP games.
RESULTS: The total effective rate and cure rate of experimental group in 6mo were higher than those of control group. The overall effective rate was 94. 4% in the experimental group and 83. 3% in the control group. There was a statistically significant difference between them (P<0. 05).
CONCLUSION: The comprehensive therapy by making use of P-VEP game is an individualized effective new way in treating amblyopia.

To establish a method based on a pseudotyped virus assay for screening drugs for anti-H5N1 avian influenza virus, and then to evaluate anti-virus activity of traditional Chinese herbal compounds with the function of purgation, detoxification, cooling the blood and reinforcing the healthy qi based on seropharmacology.

1.0?10~7 copies/mL. The HBsAg IHC staining positive cells could be observed in 6 placental tissues and 3 fetus' liver tissues,and HBcAg was also positive in 1 case of fetus' liver tissue.After co-incubating the tropho- blastic cells and HBV DNA positive serum in vitro,HBsAg expression and HBV DNA could be detected.Apoptosis of HBV-infected trophoblastic cells increased,which was demonstrated by in vivo and in vitro experiments and the apoptosis of placental cells was correlated with the cord blood HBV DNA level.The results of in vitro experiments showed that the apoptosis of trophoblastic cells increased with the elongation of infection time.After 6 months,1 of 12 newborns was positive for HBsAg,HBeAg and anti-HBc,6 was positive for anti-HBs.Conclusions The mechanism of HBV intra-uterine infection may be that HBV breaches the placental barrier and infects the fetus.The localization and replication of HBV in fetal tissues and organs are probably the important factors of chronic HBV infections in neonates.The apoptosis of trophoblastic cells may be the protective mecha- nism for the placental barrier to block the HBV intra-uterine transmission.

Objective To introduce the clinical application of neurocutaneous vascular flap on dorsal part of hand or finger for the soft tissue defect of the distal finger. Methods According to different defect sites of fingertip soft tissue, 56 flaps of 3 different kinds were devised to repair them : dorsal neurocutaneous vascular flap of the second or third metacarpal for the thumb, ulnar dorsal neurocutaneous vascular us flap of the thumb for the index, dorsal neurocutaneous vascular flap of the finger for the third to fifth finger. The largest flap was 2.1 cm×3.3 cm. Results Fifty-six flaps survived completely. The period of follow-up ranged from 6 months to 3 years. The contour and consistency of the flaps were nearly normal. Two-point discrimination was 5.4-9.6 mm. The appearance and function were satisfactory.. Conclusion The neurocutaneous vascular flap on dorsal part of hand or finger is a good flap for coverage of soft tissue defects of the distal finger.

Objective: To investigate the effect of combining acupuncture and auricular point sticking on heart rate variability (HRV) in patients with post-stroke depression (PSD). Methods: A total of 80 cases with PSD were randomized into a treatment group and a control group. The control group was intervened by oral administration of paroxetine hydrochloride, whereas the treatment group received acupuncture plus auricular point sticking base on the same oral administration. The Hamilton depression rating scale (HAMD) and HRV were measured before and after treatment in both groups. Results: The individual and global scores of HAMD significantly dropped after 8 weeks of treatment in both groups (all P<0.05). In the treatment group, anxiety/somatization factor, sleep disturbance, hopelessness factor, cognition factor and global score were significantly different from those in the control group (all P<0.05). The 24 h standard deviation of all normal-to-normal R-R interval (SDNN), standard deviation of 5-minute average of normal R-R intervals (SDANN), root mean square of successive differences (RMSSD), percent of differences between adjacent normal R-R intervals >50 ms (PNN50) and high frequency (HF) were increased while low frequency (LF) and LF/HF decreased significantly after 8 weeks of treatment in both groups (P<0.05). All items in the treatment group were significantly different from those in the control group (all P<0.05). Conclusion: Combining acupuncture and auricular point sticking can enhance the conventional medical treatment for HRV in patients with PSD.
