The immune nutrients play an important role in nutritional support,immune regulation and maintenance of intestinal barrier function.In recent years,with the deepening study,the effect of immune nutrients in the comprehensive cancer treatment has constantly being recognized.Many studies have shown that glutamine (Gln),arginine (Arg) and polyunsaturated fatty acids (PUFA) have effect on the tumor itself and the combination cancer chemotherapy.

Guided by the antioxidant activity, the EtOAc-soluble and n-butanol-soluble fractions of the 50% methanol extract of Lonicera japonica leaves were isolated and purified by various chromatorgraphic methods, and the structures were identified by spectral analysis and comparison to the data reported in literature. As a result, nine compounds were obtained and identified as 5-O-caffeoylquinicacid (1), chlorogenicacid (2), 4-O-caffeoylquinicacid (3), luteolin-7-O-[α-L-arabinopyranosyl-(1 --> 6)] -β-D-glucopyranoside (4), luteoloside (5), 3,4-di-O-caffeoylquinic acid (6), 3,5-di-O-caffeoylquinic acid (7), 4, 5-di-O-caffeoylquinic acid (8) and luteolin (9). The antioxidant activity of the nine compounds were determined by using DPPH free radical scavenging method, and ascorbic acid was used as a positive control. Their antioxidant activities from high to low were 5 > 9 > 2 > 8 > 7 > 6 > 1 > 3 > 4. Among them, luteoloside (5) had the strongest antioxidant activity with an IC50 of 0.018 18 g x L(-1), and luteolin (IC50 0.023 6 g x L(-1)) and chlorogenicacid (IC50 0.035 17 g x L(-1)) ranks No. 2 and 3. Furthermore, the antioxidant activity of luteoloside and luteolin were stronger than that of ascorbic acid (IC50 0.027 54 g x L(-1)). These results gave a basis for the further study and utilization of L. japonica leaves.

Objective To investigate the expression of human bone morphogenetic protein-7(hBMP-7)in rat bone malTOW stromal cells(BMSC)with a recombinant adenovirai vector carrying the hBMP-7 gene(Ad-hBMP-7) and study the effecta of Ad-hBMP-7 transfection on BMSC difierentiation.in order to explore the possibility for hBMP-7 gene therpy.Methods The rat BMSC cultured in vitro.They were divided into 3 groups:untreated group,Ad-hBMP-7 and Ad-GFP transduced treated group.The rat BMSC were transfected by Ad-hBMP-7 and Ad-GFP. The expression of hBMP-7 was detected by RT-PCR and Western blot analysis.and the alkaline phosphatage (ALP)activity of the BMSC was observed.ResulIs In the Ad-hBMP-7 transduced treated group.hBMP-7 mRNA expression wag manifested detected by RT-PCR(470 bp),Westem blot analysis demonstrated that these cells indeed produced the hBMP-7 protein(Mr.15×103);10 days after transduction treatment,most of the BMSC were had brown black particles stained positively by ALP activity.But in Ad-GFP transduced treated group and untreated group they did not.Conclusions Ad-hBMP-7 could efficiently transfect BMSC and promote the conversion to osteoblast.The expression of hBMP-7 in rat BMSC provides a basis for hBMP-7 gene therapv.

In vitro cell culture of head and neck tumors and chemosensitivity test to select sensitivity antitumor bogs for individual chemotherapy. Methods:The chemosensitivity of 32 fresh specimens of human head and neck tumors were tested with MTT assay and eight atitumor drugs． Results:The sensitivity was 84.4% for 5-Fu, 2l.9% for VCR, 62.5% for MTX, 8l.3% for BLM, 8l.3% for DDP, 40.6% for ADM, 65.6% for PYM and 3.l% for CTX． The results of chemotherapy with sensitivity drugs of 32 patients were encouraged． There were no serious side-effects in the chemotherapy and no recurrence and metastasis after the treatment． 32 patients were still alive． Conclusion: Chemosensitivity test of tumor cell lines with MTT assay was accuracy， fast，simple，ecoromical，effective method and was valuable for chemotherapy．

Objective To analyze the correlation of the mutations of exon 4 of pulmonary surfactant protein (SP)-B and SP-C with respiratory distress syndrome (RDS) in Mongolian premature infants. Methods Fifty cases of hospitalized genetically unrelated Mongolian premature infants with RDS ( 31 males, 19 females) were recruited as RDS group. In the same period, 50 cases ( 27 males, 23 females) of non RDS genetically unrelated premature infants of same ethnicity were choose as the control group. PCR and gene detection were used to detect exon 4 of SP-B and SP-C genes. The differences of the genovariation and genotype frequency of 1580 locus in exon 4 in SP-B, and of c. 571 C?>?A (T 138 N) locus in exon 4 in SP-C were compared between two groups. Results The genovariation of 1580 locus in exon 4 in SP-B was detected in 14 cases (with aberration rate of 28%) in RDS group and in 11 cases (with aberration rate of 22%) in control group, and the difference is not signiifcant between two groups (χ2=0 . 480 , P?>?0 . 05 ). The genotype frequency of CC, TT and CT gene in 1580 locus were 16%, 72%, and 12%respectively in RDS group;and 10%, 78%, and 12%respectively in control group. Meanwhile, the C and T gene frequency was 22% and 78% respectively in RDS group, and 16% and 84% in control group. There was no significant difference in genotype frequency between two groups (χ2=1 . 170 , P?>?0 . 05 ). The genovariation of c. 571 C?>?A (T 138 N) locus in exon 4 in SP-C was detected in 41 cases (with aberration rate of 82%) in RDS group and in 6 cases (with aberration rate of 12%) in control group, and the difference is signiifcant between the two groups (χ2=49 . 177 , P??A (T 138 N) locus were 18%, 50%, and 32%respectively in RDS group;and 88%, 8%, and 4%in control group. Meanwhile, the C and A gene frequency was 34%and 66%respectively in RDS group, and 90%and 10%in control group. There was a signiifcant difference in A gene frequency between the two groups (χ2=66 . 553 , P??A (T 138 N) locus in exon 4 in SP-C gene were in a higher risk of RDS. The mutation of 1580 locus in exon 4 in SP-B had no correlation with Mongolian premature RDS.

OBJECTIVETo investigate the blood supply of the pedicle fat grafts with the third lumbar segmental artery and its clinical effects on reoperation for lumbar disc herniation.

METHODSTwelve sides of 6 adult cadaver examples were contributed to investigate the courser of lumbar segmental vessels and the distribution of hypodermic capillary net of the dorsal branch of the third lumbar segmental artery. From January 2000 to January 2007,49 patients needed reoperation to treat lumbar disc herniation,including 26 males and 23 females with an average age of 55.6 years (ranged from 39 to 70 years). Duration between two operations ranged from 8 months to 15 years with an average of 6.9 years. Reoperative reasons included recurrent lumbar disc protrusion(30 cases)postoperative epidural scar formation (17 cases), postoperative epidural cyst formation (2 cases). Of them,9 patients underwent posterior lumbar interbody fusion at the second operation. The pedicle fat grafts with the third lumbar segmental artery were covered on the sites of the laminectomy in these patients. After negative pressure drainage tube were pulled out, 2 ml Chitsan were injected to the sites of the laminectomy and around epidural nerve root through epidural catheter. VAS score and the Oswestry Disability Index (ODI) were used to assess clinical outcomes before and after operation.

RESULTSThe courser of third lumbar segmental vessels were invariant at the lateral face of the lumbar vertebral body. The dorsal branch of the third lumbar segmental artery penetrated thoracolumbar fascia and formed rich hypodermic capillary net in the region. All patients were followed up from 5 to 8 years with an average of 5.6 years. VAS score of low back pain and leg pain decreased respectively from preoperative 7.6 +/- 1.2, 8.9 +/- 0.9 to 3.6 +/- 0.5, 3.0 +/- 0.4 at final follow-up (P < 0.01); and ODI score decreased from preoperative 44.1 +/- 6.2 to 13.9 +/- 3.6 at final follow-up (P < 0.01). According to ODI score to evaluate the clinical outcomes, 29 cases got excellent results, 11 good, 7 fair, 2 poor.

CONCLUSIONThe pedicle fat grafts with the third lumbar segmental artery and Chitsan can reduce epidural scar formation and prevent peridural fibrosis and adhesion and improve clinical effects of reoperation for lumbar disc herniation.
