Objective To approach the method for improving the intellectual development,of whom had suffered from parity′s brain damage.Methods The patients were divided into 2 groups randomly(age range from 7 days to 18 months) who were observed and compared for 3 years.Group A was bundle of intervention which had been under early intervention program since infant.Group B was bundle of comparing of which had not been under early intervention.Results Observed for 6 months and 12 months,the intellectual development of group A was prior to that of group B(age 6 months P

To study photosynthetic characteristics and its influencing factors in leaves of medicinal plant Mirabilis himalaica, and provide an evidence for guiding artificial planting and improving the quantity. The light-response and diurnal photosynthesis course of leaves at the booting stages of 1-3 year old M. himalaica were measured with LI-6400 system. The Results showed that the light response curves were fitted well by non rectangle hyperbola equation (R2 > or = 0.98). The values of the maximum photosynthetic rate (Pmax) and light use efficiency of three-year old M. himalaica leaves were higher than those of 1-2 year old individuals. The diurnal variation of net photosynthetic rate (Pn) and stomatal conductance (Gs) of 2-3 year old M. himalaica were typical double-peak curves determinately regulated by stomatal conductance. However, transpiration rate (Tr) of 1-3 year old plants leaves were single-peak curve, which was self-protection of harm reduction caused by the higher temperature at noontime. Correlation analysis showed that the changes between photosynthetic active radiation (PFD), air temperature (T ) and Pn, were significant positive related. Therefore, M. himalaica is a typical sun plant, which should be planted under the sufficient sunshine field and prolong the growing ages suitably in order to improve the yield.

OBJECTIVETo compare therapeutic effects between the normal rehabilitation and combined with manipulative method after arthroscopic capsular release for the treatment of severe frozen shoulder, and to evaluate the application value of manipulationp.

METHODSFrom March 2007 to July 2010,arthroscopic capsular release was performed in 48 cases (48 shoulders, 23 left side, 25 right side). All the patients were divided into two groups: control group (11 males and 15 females) and manipulation group (9 males and 13 females). The patients in the control group were treated with conventional rehabilitation procedure, and the patients in the manipulation group were treated with additional manipulation procedure. From the 2nd day after operation, the manipulation was performed for 20 minutes every time, twice daily, and it continued for 10 days. All the cases were followed up and the scale of American Shoulder and Elbow Surgeons Standardized Assessment Form (ASES self-report section) and the range of motion (ROM) were recorded.

RESULTSThe mean follow-up period was (12.54 +/- 5.78) months (ranging from 4 to 25 months). Both ASES scores and ROM in the manipulation group were better than those in the control group at the 1st month after operation, and the difference between the ASES scores and flexion of the shoulder were significant. However, there was no significan difference at the latest follow-up.

CONCLUSIONCompared with the conventional rehabilitative procedure, manipulation following arthroscopic capsular release could promote the process of joint rehabilitation and help the patient back to normal life earlier, but there is no evidence of long term advantage.

This study aims to investigate the relationship between odor and contents of the chemical compounds in Lonicera japonica, including chlorogenic acid, galuteolin and polyphenols. High performance liquid chromatography (HPLC) was applied to determine the contents of chlorogenic acid and galuteolin in L. japonica. The ponptent of polyphenols was determined by UV-Vis Spectrophotometry. Electronic nose was used to extract and measure the odor of L. japonica. Then SPSS 17.0 software was employed for data processing. There is a significant positive correlation between the comprehensive index value of aroma and the contents of chlorogenic acid and polyphenols. The regression equations have been established. However, the relationship between the comprehensive index value and the content of galuteolin is not obvious. This is proof that the odor of L. japonica has close connection with the chemical compounds. Therefore, this research offered a new method for initially determine or predict the content of the chemical composition in L. japonica,

Objective　 To investigated the possible roles of IL-18 in HBV infection, and the expression of IL-18 in the peripheral blood mononuclear cells (PBMC) of chronic hepatitis B. Methods 　In 15 cases of asymptomatic carriers, 30 cases of active and remissive phases of chronic hepatitis and 10 healthy individuals (as normal controls), IL-18 expression in PBMC were quantitatively analyzed with flow cytometric immunological method. The PBMC were separated routinely and stimulated with LPS (SIGMA) and Monensin (SIGMA) for 6 hours. Then the cells were harvested and fixed by PBS/4% paraformaldehyde. The treated cells were stored in liquid nitrogen for detection later. After immunologic stain, the expression of IL-18 in PBMC were examined by flow cytometry. Results　 ① IL-18 was the lowest in asymptomatic carriers. It was fewer in remissive phase than in normal controls (P＜0.01).There was no difference between active phase and normal controls(P=0.25).②Within the group of active phase, IL-18 was significantly different between each grade of inflammatory activity(P＜0.01),and correlated with serum ALT positively(r=0.63,P＜0.01). Conclusion　 IL-18 may relate to disease activity and the inflammation of liver.

Objective To investigate rite effects of loag-term exposure to low-level sevoflurane on reproductive function in mice.Method F0ny male ICR mice,aged 60 d,weighlag 20-25 g,were randomly divided into 4 groups(n=10 each):control group received no sevoflunme(C);group S1-3 were exposed to 0.003%.0.01% and 0.03% sevoflurane 2 h per day for 5 consecutive days per week for 8 weeks respectively. The mice were then sacrificed at the end of the 8 weeks.The testes and epididymis were emoved and sampled for determination of the activities of total lactic dehydregenase(LDH)and lactic dehydrogenase-X(LDH-X),and the motility rate,amount,and aberration rate of sperm.Testicular uhrastructure were observed by transmission electron microscopy.Results The sperm motifity nne were significantly lower.the sperm aberration rate higher and the activity of LDH-X lower in group S3 than in group C(P<0.05),but there was no significant difference in the above parametem between group SI and group S2(P>0.05).The pathology changed of testes occurred only in group S3 among the 3 groups.Conclusion Long-term exposure to 0.03% sevoflurane can result in the abnormality of the reproductive function in male mice but exposure to≤0.01%sevoflurane dose not.

Objective To establish a simple and sensitive method for the determination of serum copper by spectrophotometry.Methods Nitro-PAPS was used as a coloring agent for serum copper in the presence of surfactants Tween-80 and Triton X-100 and the formed complex was measured by spectrophotometry.Results The maximum absorption wavelength of the complex was 570 nm and the molar absorption coefficient was 7.95?10~4 L/(mol?cm).The lineafity of the method was up to 63.0 ?mol/L and the recoveries ranged from 98.6% to 103.1%.The within-run and between-run CVs were 2.1%-3.3% and 2.7%-3.8%.The method(Y)was compared with an AAS method(X)and a correlation of Y=1.01X -0.27(r=0.998 2)was obtained.A reference interval(x~-?2s)determined with this method on 68 individuals was 9.7-24.1 ?moL/L.Conclusions A simple and sensitive method for serum copper has been established.It may used for the analysis of serum copper in clinical laboratories.

Many bioactive peptides from neural and endocrine tissue are amidated at C-terminals,which is essential for their activities.The ?-amide comes from post-translational modification that is catalyzed by ?-AE (?-amidating enzyme) or PAM (pepdilylglycine ?-amidating monooxygenase).The gene encoding ?-AE was amplified with PCR and cloned into the plasmid pET-30a.After the recombinant plasmid pET-A was transformed into E.coli BL21,the ?-AE was expressed and purified by the Ni2+affinity chromatography,which has the ability catalyzing Dns-Tyr-Val-Gly to Dns-Tyr-Val-NH2.It identified that the recombinant protein producing by E.coli BL21 is ?-AE,which will benefit for studies of amidation at the C-terminals of peptides.
