Objective: To observe the effect of Yi Jin Jing (Sinew-transforming Qigong Exercises) on the muscle strength in senile sarcopenia. Methods: Sixty-five old people with sarcopenia were randomized into Yi Jin Jing group and a blank control group. Thirty-three patients in Yi Jin Jing group practiced Yi Jin Jing (Sinew-transforming Qigong Exercises), while 32 patients in the blank control group didn't receive any interventions. The muscle strength was measured before and after 12-week training. Results: During the study, each group had 1 dropout. The muscle strength was improved after 12-week training in Yi Jin Jing group, and the difference was statistically significant (P<0.05); there was no significant difference in the blank control group (P>0.05). After the intervention, there was a significant difference between Yi Jin Jing group and the blank control group in comparing the muscle strength (P<0.05). Conclusion: Constant Yi Jin Jing (Sinew-transforming Qigong Exercises) training can notably improve skeletal muscle strength in senile sarcopenia.

To compare the effect and advantage of performing rhegmatogenous retina detachment surgery under operation microscope with under direct ophthalmoscopes .METHODS: Ninety - three patients ( 93 eyes ) were randomized to two groups, Group A ( under operation microscope during rhegmatogenous retina detachment surgery, 47 cases ) , Group B ( under direct ophthalmoscopes during rhegmatogenous retina detachment surgery, 46 cases ) . All patients were followed up for 2wk to observe success rate and visual improving rate.RESULTS: Total percentage of success was 95. 74% in group A and 80. 43% in group B. The visual improving rate of group A was 82. 98% and it was 67. 39% in group B. Operative time in group A was significantly shorter than that in group B (P<0. 05). CONCLUSlON: Performing rhegmatogenous retina detachment surgery under operation microscope is ascertaining and it is more effective and handy than performing that surgery under direct ophthalmoscopes.

Objective To investigate the correlation between the plasma unconjugated bilirubin(UCB)and electrical activity of brain in term neonates with hyperbilirubinemia,and explore the parameters that possess the prognostic value and deduce a series of discriminant for prognostic judgment.Methods Thirty-two neonates with hyperbilirubinemia and 31 neonates without hyperbilirubinema(control group)were studied with standard EEG,and they were assessed for their neurological development in 3 and 6 months.A statistical method of Bayes Discriminant analysis was adopted to set up an equation with values of parameters of EEG,clinic datum and consequence.Stepdic and Dis-grim processes were used to pick out the parameters which had great significance for predicting the outcome of nervous system development.A series of discriminant was deduced for prognostic judgment and then cross validation was performed to assess the accuracy of the discriminant.Results 1.The standard EEG and brain electrical activity map records indicated that the hyperbilirubinemia group had longer maximum duration of interburst interval(IBI),longer mean duration of IBI,lower amplitude under all conditions,more anterior dysrhythmia(AD)in wake,and higher incidence of sleep-wake cycle disturbance.2.The plasma concentration of UCB was linear correlated with AD in wake.3.Gestational age,birth weight,plasma concentration of UCB,burst duration of IBI in trace alternate,amplitude in all sleep state,AD in wake,brief burst not in quiet sleep and sleep-wake cycle disturbance might play important roles in predicting the outcome of neonates with hyperbilirubinemia.Conclusions Cerebral electrical activity is an effective tool for predicting neurologic outcome of neonates with hyperbi-lirubinemia.Cerebral electrical activity and clinic data will provide a new method for accurately predicting neurological development and prognosis.

To evaluate in vitro release and transdermal behaviors of Huoxue Zhitong gel, modified Franz diffusion cell methods was applied to investigate in vitro transdermal absorption of Huoxue Zhitong gel and the content of paeonolan in receptor fluid composed of PEG400%-95% ethanol-water (l:3:6)were determined by HPLC. The results were processed and different equations were fitted. The release law were in accordance with Weibull equation and the fitting equation was In[-1/(1 - Q)] = -0.790 51nt - 1.7012 (r = 0.9809). In 8 hours, cumulative release of paeonol was 85. 18% and the release rate was 2.827 µg . cm-2 h-1. Transdermal actions were consistent with zero-level model fit and the fitting equation was Q(t) = 1.7579t + 0. 7213 (r = 0.9991). In 8 hours, cumulative transdermal rate and transmission rate of paeonol was 54. 85%, 1. 820 µg . cm-2 h-1. So the Huoxue Zhitong gel had a good release and transdermal properties.

The hom gene encoding for homoserine dehydrogenase was amplified from the genomic DNA of Corynebacterium glutamicum ATCC 13032.After the kanamycin-resistant gene(Km)cassette from plasmid pET28a was inserted into the center of hom,the hom::Km cassette was then electroporated into the competent cell of C.glutamicum ATCC 13032.And kanamycin-resistant clones were obtained.PCR was performed to confirm whether the Km gene was integrated into the hom gene of these clones and the recombinant strains of hom-disrupted were screened out.Fermentation results showed that the lysine yield of the hom-disrupted strain C.g-hom::Km-8 reached 4.7 g/L,which was 6.7 times that of C.glutamicum ATCC 13032.

In order to isolate genes related with the osmoadaptation and glycerol metabolism of Candida glycerinogenes, a transformation system based on the dominant selectable marker Zeocin and restriction enzyme-mediated integration (REMI) was established. Effects of seven restriction enzymes on transformation efficiency of C.glycerinogenes were tested. Transformation conditions were optimized in the presence of Hind III. Under the optimal conditions of OD_ 600 ≈1.3, voltage of 1.5 kV, 2.0?10~9 competent cells/mL, 100 units of Hind III added, the transformation efficiency was up to 129 trnaformants/?g DNA. 58% of transformants were stable on nonselective medium. These results suggest that REMI technique would be beneficial to the genetic transformation of C.glycerinogenes.

A method to determine dihydroxyacetone (DHA) in fermentation broth was developed by high performance liquid chromatography (HPLC). DHA was separated on a Alltima C18(5?m,250?4.6mm). The mobile phase was 0.5% methanol solution (pH adjusted to 3.0 with H3PO4), the flow-rate was 1.0 ml/min and the detective wavelength was 200 nm. The detection limits of DHA was 0.1 g/L~10.0 g/L. 6.2 g/L DHA in the fermentation broth was detected by HPLC, which was in agreement with the result by spectrophotometric method.The method was applicable for DHA determination in the fermentation process.

More than 20 strains capable of producing dihydroxyacetone from glycerol were isolated from 4 different natural environment samples by using two detection methods. The strain 6-8 which could grow on medium containing glycerol as sole carbon source had a higher converting capability. Under a better culture, the highest DHA production of the strain 6?8 reached 6.4 g/L. In addition to general morphological and bio-chemical characteristics, the strain 6?8 was identified by 16S rDNA sequence and systematic analysis. The results showed that 16S rDNA sequence of the strain 6-8 had similarity of 99.7% with Acinetobacter sp. suggesting that the strain 6-8 is one of subspecies of Acinetobacter sp.
