Objective: To evaluate the clinical effect of individualized enteral nutritional (EN) support in severe stroke patients.Methods: Totally 120 severe stroke patients with nutritional risk were divided into two groups according to single or double admission number.The 60 patients in the intervention group received an individualized EN with different formula and concentrations according to the clinical status,and supplemented trace elements as occasion required.In the routine group, the patients received EN with standard formula.The energy supply was 83-125 kJ· kg-1·d-1 in both groups.Blood albumin(Alb), pre-albumin(PA), hemoglobin(Hb) and vitamin C(VC) were examined before and after the 21-day nutritional support.The lung infection and gastrointestinal (GI) complications were observed, and the hospital stay and cost were recorded as well.Results: After 21 day''s nutrition support, the serum levels of Alb, PA and VC in the intervention group were not statisticly significant than before (P＞0.05), and the serum levels of Alb, PA and VC were significantly higher than those in the routine group(P＜0.05).The incidence of complications in the in the intervention group was lower than that in the routine group (P＜0.05), and the length of hospital stay and hospitalization was shorter than that in the routine group (P＜0.05).Conclusion: Individualized enteral nutritional support can significantly improve nutritional status, reduce inflammation reactions and GI complications in severe stroke patients, which is worthy of clinical use.

Objective To study the clinical application of the complete audiologic evaluation battery consisting of ABR,ASSR and behavioral audiometry in sound field for the identification of sensorineural losses in children.Methods In the study 48 children were divided as group PTA of the children assessed by pure tone audiometry and ABR and ASSR test,and group BA of the children unable to perform on behavioral evaluations.Results The analysis of the audiometric results of group PTA showed significant correlation between the ASSR thresholds and pure tone thresholds(P＜0.01) at various frequencies.The correlation coefficients were 0.75,0.76,0.76,and 0.83 at different frequencies.The ASSR-PTA linear regression was utilized.The comparison of the ABR and ASSR results of group BA indicated that 23 ears responded in ASSR but without responses in ABR.Those without ASSR responses also had no ABR There were 116 tests in total four frequencies for the 29 ears.83 responses were obtained from ASSR,89 responses from behavior audiometry and 96 from the use of the both tests.Conclusion The comprehensive audiologic evaluation battery could be used to test younger children with severe heating loss children as compared to the pure tone audiometry alone.More detailed data can be obtained thus from children to assist in rehabilitation in a more effective mariner.

50 days),whereas third party skin grafts were vigorously rejected.Conclusion Blockade of CD28-B7 and CD40-CD40 ligand interactions resulted in long-term allograft survival and donor-specific tolerance in mouse cardiac transplantation without chronic rejection.

Objective To study the expression and its clinical significance of Oct4 in prostate cancer.Methods The Oct4 mRNA expression levels in 2 normal prostate (NP) samples and 8 prostate cancer (Pca) samples were determined by reverse transcription polymerase chain reaction (RT-PCR) analysis.The Oct4 protein expression levels in 10 NP samples,10 benign prostate hyperplasia (BPH) samples and 45 Pca samples were detected by immunohisochemical analysis.Results The relative expression levels of Oct4 mRNA were 0.91,0.76,0.66,0.63,0.55,0.50,0.48,0.42 in 8 Pca samples and 0 in 2 NP samples,respectively.The positive rates of Oct4 protein expression was higher in Pca tissues than in NP and BPH tissues (91.1％ vs.0.0％,91.1％ vs.0.0％,both P＜0.05).The level of Oct4 protein was increased with higher hostologic grade and clinical stage of prostate cancer.The strong positive rates of Oct4 expression were 72.7％ and 30.0％ in Pca tissues with and without lymph node metastasis respectively,and there was a significant difference in the strong positive rate between them (P＜0.05).Conclusions The Oct4 expression is closely related to the differentiation and invasion of tumor.Oct4 might be an important index for the prognosis of prostate cancer.

Objective:To study the effects of recombinant human platelet-derived growth factor-BB(rhPDGF-BB)combined with recombinant human transforming growth factor-β1 (rhTGF-β1 )on the expression of FAK mRNA of osteoclasts in the alveolar bone on the pressure side of orthodontic teeth in rats.Methods:Orthodontic tooth movement model was established in 160 male SD rats.The rats in experimental group were treated by injection of 10 ng rhPDGF-BB and 5 ng rhTGF-β1 in the buccal submucosal area of the mo-lar every other day from day 1 afterburner,while those in control group received equivalent volumes of PBS.The rats were sacrificed at 1,4,7,10 and 14 days(n=16)after appliance placement.Specimens were collected.Osteoclasts in the alveolar bone on the pres-sure side of the orthodontic teeth were observed by TRAP staining,the FAK mRNA expression was quantified by quantitative RT-PCR.Results:rhPDGF-BB combined with rhTGF-β1 significantly promoted an increasing number of osteoclasts on the compressing side(P<0.05),increased the expression of FAK mRNA at day 4 and 7(P<0.05),then decresed it to the control level(P>0.05) at day 14.Conclusion:Combination of rhPDGF-BB and rhTGF-β1 can increase the number of osteoclasts in the alveolar bone on compressing side,and promote FAK mRNA expression in osteoclasts.

0.05). Conclusion Preproghrelin-Leu72Met is not significantly associated with T2DM and DN in Shanghai Han populations,while T2DM with AA genotype is characterized by significant declination in urine microalbumin when compared with CA and CC genotypes.Leu72Met polymorphism(C→A)may postpone the development of microalbuminuria in T2DM subjects.

With homology cloning approaches coupling with RACE (rapid-amplification of cDNA ends) techniques, the full-length coding sequence of pathogenesis-related protein PR10-1 with differential expression was cloned from the total RNA of the root of Panax notoginseng, and its function was explored furtherly. As a result, the longest 465 bp ORF (named as PnPR10-1 with the Accession No. KJ741402 in GenBank) was detected from the cloned sequence with full-length of cDNA of 863 bp. The corresponding peptide encoded consisted of 155 amino acids, contained some domains such as Bet-v-I, and showed high similarity with that from Panax ginseng by analysis of phylogenetic trees created from the alignments. Real-time quantitative PCR showed that the expression of PnPR10-1 gene was constitutive in different tissues of 1-3 year old plant, suggesting that it might be involved in growth, development, and secondary metabolism; yet it was up-regulated significantly with the infection of Fusarium oxysporum in root, suggesting that it might be involved in defense against many diseases including root rot in P. notoginseng.

OBJECTIVETo investigate different treatment methods for stage-Is testicular mixed germ cell tumors (TMGCTs).

METHODSWe retrospectively analyzed the clinical data about 3'cases of stage-Is TMGCTs (aged 26-39 years) treated in the 175th Hospital of PLA, reviewed relevant literature, and explored the clinical characteristics of TMGCTs.

RESULTSOf the 3 patients, 1 was treated by radical orchiectomy, 1 by radical orchiectomy + retroperitoneal lymph node dissection + BEP chemotherapy scheme, and the other by radical orchiectomy + radiotherapy. The pathological components of TMGCTs were immature teratoma, seminoma, spermatocytoma, chorioepithelioma, embryonal carcinoma, and yolk sac tumor. No recurrence or distant metastasis was found during the 24-month follow-up after surgery.

CONCLUSIONThe diagnosis of TMGCTs primarily depends on physical examination, ultrasonography, MRI, and measurement of serum tumor markers, while its confirmation necessitates pathological examination, and its treatment is basically radical orchiectomy.
