Long noncoding RNA ( lncRNA) is a functional RNA molecule longer than 200 nucleotides.They are involved in epigenetic, transcriptional and post-transcriptional modifications, playing an important role in gene expres-sion, chromatin remodeling, histone modification, X chromosome inactivation, genomic imprinting, protein folding and ac-tivity as well as other important biological events.Some studies have proven that lncRNAs are involved in the development of metabolic diseases.The changes of their expression levels may be new diagnostic markers and therapeutic targets.

Objective To study the effect of 3％ hypertonic saline(HS) and 20％ mannitol on cerebral oxygen metabolism in patients undergoing neurosurgery for supratentorial glioma.Methods 56 patients undergoing neurosurgery for supratentorial glioma were evenly divided into two groups.Group A(n =28) was treated by 3％ hypertonic saline(5.35ml/kg).Group B (n =28) was treated by 20％ mannitol(1 g/kg).CSFP was tested before hypertonic saline or mannitol infusion (T0),immediately (T1),15,30,60,120min after infusion (T2 ～5).Various blood-gas indexes were observed at To,T3 ～5.CaO2,CjvO2,Da-jvO2 and CERO2 were calculated.Results CSFP significantly dropped from T2 to T5 in both groups (P ＜ 0.05).Da-jvO2 and CERO2 were significantly reduced at T4～5 in both groups (P ＜ 0.05).There was no significant difference between the two groups.Conclusion 3 ％ HS is as efficient as 20％ mannitol in reducing intracranial pressure and improving cerebral oxygen metabolism in patients undergoing neurosurgery for supratentorial glioma.

Objective To determine the brain protective effects of inhalation anesthetic pretreatment in infants undergoing open-heart surgery under extracorporeal circulation (ECC).Methods Forty-five infants (no more than 3 years old) with congenital heart diseases who received surgical treatment were divided into 3 groups by table of random digit,sevoflurane pretreatment group (group S,15 cases),isoflurane pretreatment group (group Ⅰ,15 cases) and control group (group C,15 cases).In pretreatment group,all infants had been inhaled 1.0-1.5 MAC sevoflurane or isoflurane continually for over 60 min after intubation,while group C did not receive pretreatment.Blood samples were taken before (T1) and in 5 min after ECC (T2),occlusion of aorta (T3),30 min after ECC (T4),end ofECC (T4),and 6 and 24 h after the end of ECC (T6 and T7).Serum levels of S 100 β protein and neurone specific enolase (NSE) were measured by enzyme-linked immunosorbent assay.Results There was no significant difference in the serum levels of S100β protein and NSE among the 3 groups in T1 (P＞0.05).There was no significant difference in the serum levels of S100β protein and NSE in group S and group Ⅰ between T1 and T2-7 (P＞ 0.05).There was no significant difference in the serum levels of S100 β protein and NSE in T2-7 between group S and group Ⅰ (P ＞ 0.05).In group C,there were significant differences in the serum levels of S100 β protein in T4-6 and NSE in T4-7 than those in T1 (P＜ 0.05).In T4-6,the serum levels of S100 β protein and NSE in group S and group Ⅰ were significantly lower than those in group C [S100 β protein:(0.45 ± 0.31),(0.47 ± 0.35) μ g/L vs.(0.73 ± 0.31) μ g/L,(0.53 ± 0.33),(0.54 ± 0.36) μ g/L vs.(0.91 ± 0.30) μ g/L,(0.47 ± 0.34),(0.49 ±0.35) μ g/L vs.(0.79 ± 0.40) μ g/L,P ＜ 0.05； NSE:(3.26 ± 1.34),(3.32 ± 1.34) μ g/L vs.(7.20 ± 2.71)μ g/L,(5.57 ± 1.49),(5.61 ± 1.52) μ g/L vs.(7.68 ± 3.68) μ g/L,(2.29 ± 1.21),(2.34 ± 1.22) μ g/L vs.(9.46 ± 4.61) μg/L,P ＜ 0.05].Conclusion Sevoflurane or isoflurane pretreatment significantly decreases the serum levels of S100 β protein and NSE during open-heart operation in infants with ECC.

Objective: To apply chromogenic in situ hybridization (CISH for detection of HER2 gene amplification in breast cancer tissues and to discuss some modifications of the CISH method. Methods: HER2 gene amplification was detected by CISH in 60 breast cancer specimens with an immunohistochemical score over 2+. The correlation between the results of IHC and CISH was analyzed. Our experience in CISH manipulation was summarized and optimization to CISH was discussed. Results: CISH identified gene amplification in 91% (40/44) specimens with an IHC score of 3+ and in 50% (8/16) specimens with an IHC score of 2+. The total concordance rate between IHC and CISH was 80% (48/60, P<0.01). The thickness of sections should be controlled within 4-5 μm; the denaturation should be complete; and the post-hybridization washing temperature and time were also very important and the temperature should be controlled at 70-75 °C. The dyeing time of hematoxylin should also be restrictedly controlled. Positive control should be set up in the experiment for high quality of the experiment. Conclusion: CISH has high concordance rate with IHC in examining HER2 amplification and it may be a new method for detection of HER2 gene. The thickness of the sections, the post hybridization washing temperature and time, and the time of hematoxylin dyeing should be strictly controlled.

OBJECTIVETo compare the therapeutic effect of Astragalus and Angelica Mixture (AAM) on treating CKD patients according to different CKD primary diseases, staging and TCM syndromes.

METHODSA multicentre, open-label, and self control clinical design was used, and thirty-two patients in line with inclusive criteria were recruited. Based on maintaining their previous basic CKD treatment, patients additionally took AAM (Astragalus and Angelica each 30 g), once a day, three months consisted of one therapeutic course. Serum creatinine (SCr), estimated glomerular filtration rate (eG- FR), 24 h urinary total protein (UTP), plasma albumin (ALB), hemoglobin (Hb), and changes of TCM syndrome factor integrals were compared before treatment, at the end of month 1, 2, and 3. The differences in the aforesaid indices were compared between CKD patients with different CKD primary diseases (chronic glomerulonephritis, chronic renal tubulointerstitial disease, hypertensive renal damage), different CKD stages (CKD 3 and CKD 4), and patients of qi-blood deficiency syndrome (QBDS) and non-QBDS.

RESULTSAAM could improve 78.12% (25/32) patients' renal function. Compared with before treatment, SCr decreased (12.08% +/- 10.11%), eGFR increased (21.14% +/- 18.55%), and ALB increased (2.76% +/- 1.97%) at the end of 3-month treatment (all P < 0.05). As for TCM syndrome factor integrals, compared with before treatment, the integrals for qi deficiency syndrome, blood deficiency syndrome, and yin deficiency syndrome decreased, while the integrals for dampness heat syndrome and turbid-toxin syndrome increased (all P < 0.05). There was no obvious difference in all indices except the integral for hypertensive renal damage patients of yin deficiency syndrome (P > 0.05). The SCr decreasing percent was 19.82% +/- 8.30% for patients of non-QBDS and 5.24% +/- 10.75% for patients of QBDS. The latter was higher with statistical difference (P < 0.05). As for TCM syndrome factor integrals, the integral differences of qi deficiency and blood deficiency were obviously higher in patients of QBDS, when compared with patients of non-QBDS (P < 0.05).

CONCLUSIONAAM could improve the renal function of CKD patients, elevate their ALB levels, and ameliorate associated qi deficiency syndrome, blood deficiency syndrome, and yin deficiency syndrome, especially for CKD patients of QBDS.
