Objective Kidney-supplementing and blood-activating method was adopted in treating senile patients with isolated systolic hypertension to observe its decompression effects and influences on microalbunminuria (Malb),retinol binding protein (RBP) level in 24 hours.Methods 90 patients with simple systolic hypertension were randomly recurited into two groups.52 cases in the treatment group were administered with kidney-supplementing and blood-activating decoction,including 1 case falling off and 51 cases entering statistical analysis; 38 cases in the control group were administered with oral placebo,among them 2 cases were fallen offand 36 cases were entered statistical analysis.Both groups were treated for 8 weeks.Results () Blood pressure:systolic blood pressure at 4 and 8 weeks after the treatment in the treatment group [(144.03±12.33)mmHg (1 mmHg=0.133kPa) and (132.27±13.15)mmHg] wassignificantlyimproved than before the treatment [(156.32±12.05)mm Hg] (P＜0.05),and also significantly better than the control group at 4,8 weeks after the treatment [(151.19± 13.83)mm Hg,(152.74± 12.03)mm Hg] (P＜0.05).②The Malb,RBP level:Malb,RBP level [(40.80±13.51)mg/L,(150.43±23.62)mg/L] after the treatment in the treatment group was reduced than before the treatment [(50.14± 15.61)mg/L,(220.04±30.20) mg/L] (P＜0.05),and was significantly different to the control group after treatment [(52.12±14.69)mg/L,(219.34±34.37)mg/L] (P＜0.05).Conclusion Kidney-supplementing and blood-activating method can improve kidney function,and thus to reduce the effect of systolic blood pressure.

To obtain the recombinant tumor necrosis factor-α converting enzyme (TACE) ectodomain and use it as a selective molecule for the screening of TACE peptide inhibitors, the cDNA coding catalytic domain (T800) and full-length ectodomain (T1300) of TACE were amplified by RTPCR, and the expression plasmids were constructed by inserting T800 and T1300 into plasmid pET28a and pET-28c respectively. The recombinant T800 and T1300 were induced by IPTG, and SDSPAGE and Western blotting analysis results revealed that T800 and T1300 were highly expressed in the form of inclusion body. After Ni2+-NTA resin affinity chromatography, the recombinant proteins were used in the screening of TACE-binding peptides from phage display peptide library respectively. After 4 rounds of biopanning, the positive phage clones were analyzed by ELISA, competitive inhibition assay and DNA sequencing. A common amino acid sequence (TRWLVYFSRPYLVAT) was found and synthesized. The synthetic peptide could inhibit the TNF-α release from LPS-stimulated human peripheral blood mononuclear cells (PBMC) up to 60.3 %. FACS analysis revealed that the peptide mediated the accumulation of TNF-α on the cell surface. These results demonstrate that the TACE-binding peptide is an effective antagonist of TACE.

Background Patients often suffer from a few complications of neurological and psychiatric problems after traumatic brain injury including damage of cognition, mental disorders and behavior problems. Damage of cognition is a common sequela in traumatic brain injury. Numerous researchers were focus on the cognition changes of patients with mild brain injury. But their conclusions are debatable. Executive function is one of the important components of cognition. In this study,we tried to find out the executive functional alterations of the patients with mild brain injury.Methods 159 patients with brain injury caused by transportation events and 68 normal controls were assessed executive function. The executive function tests included the block design in WAIS, the Stroop test, the verbal fluency and the modified version of Wisconsin card sorting test (M-WCST). These tests were applied to compare the scores of traumatic brain injury patients with various severities including mild, moderate, and severe and with different CT/MRI results.Results Patients with mild head injury got significantly lower scores on all tests than normal controls ( P＜0.01 ). But there was no significant difference between mild and moderate brain injury group. Except Stroop test and WCST categories, patients with mild brain injury got significantly lower scores on all other tests than those with severe brain injury ( P ＜0.05). In the brain injury cases with damage signs on CT/MRI, there was no significant difference on scores of all tests except block design tests among brain injury patients with various severities. Among the brain injury cases without any damage signs on CT/MRI, there was no significant difference on scores of all tests among brain injury patients with various severities. The correlation analysis showed that scores of block design and verbal fluency test were negatively related to the severity of brain injury( P＜0.05). The age and the education level of the patients had negative and positive correlation, respectively, to executive function.Conclusions The executive function of patients with mild brain injury was impaired when the medication was terminated. We should pay more attention to patients with mild brain injury by performing various tests for assessment of disability.

OBJECTIVE To investigate the clinical efficacy of microwave ablation in treating snoring and obstructive sleep apnea hypopnea syndrome(OSAHS). METHODS Eight patients with snores and 48 with OSAHS were included in the study. They all received micro-surgeries including plastic operations on the uvula and soft palate,tonsil ablation and tonsillectomy,inferior nasal concha and adenoid ablation,and de-volume of the tongue root. Symptoms six months before and after surgery were monitored by Polysomnography(PSG). RESULTS In 56 cases, the patients’ throats were widened. The mean values of the apnea hypopnea index(AHI), the lowest saturations (LSaO2) and the snoring index were significantly different before and after surgery(P

Objective To explore the effect of oxLDL on CXC chemokine growthregulated oncogene α (GROα) expression in human endothelial cells and the possible functional signific ance of the effect Methods LDL was isolated by sequential ultracentrifugation and oxidized to oxLDL Rever se transcriptionpolymerase chain reaction with GAPDH as internal standard was applied and CXC chemokine GROα mRNA in endothelial ECV304 cells was examined ELISA was used to determine GROα protein expression on ECV304 cell surface and in the medium With static cell adhesion assays, the physiological significa nce of elevated GROα expression was tested Results OxLDL, not LDL, treatment of ECV304 cells significantly induced the expression o f GROα mRNA that was not detectable in untreated cells Induction of expressio n was first evident at 1h, became maximal at 2h, and was substantially decre ased by 4h In a concentration and timedependent manner, oxLDL, and not L DL, induced a significant upregulation of GROα surface expression in ECV304 cel ls that was at a barely detectable level in unstimulated ECV304 cells GROα protein in the medium did not change significantly Exposure of ECV304 cells to 40μg protein /ml oxLDL for 24h resulted in a marked increase in the number of U937 cells bound to ECV304 cells and antibodies to GROα inhibited adhesion Conclusion OxLDL functionally upregulated GROα expression in endothelial cells

Objective To investigate the relationship between serum progesterone level at the day with human chorionic gonadotrophin (hCG) administration and pregnant outcome from in in-vitro fertilization-embryo transfer(IVF-ET). Methods From Mar. 2002 to Apr. 2007, 786 cycles with serum progesterone measurement on the day of hCG administration for final oocyte maturation in IVF were analyzed retrospectively in Reproductive Medicine Center in First Affiliated Hospital of Nanjing Medical University.All stimulations were down-regulated with gronadotrophin release hormone agonist (GnRH-a) in both long protocols and short protocols before gonadotrophin stimulation. When the thresholds of serum progesterone were set at 5.5, 6.0,6.5,7.0,7.5,8.0,8.5 and 9.0 nmol/L, respectively. If the level of progesterone was less than the thresholds, those patients were in lower progesterone group, on the contrary, more than the threshold value, those patients were in higher progesterone group. The laboratory results and the clinical outcomes between all patients at lower and higher progesterone group at different thresholds value were analyzed. Results The rate of normal fertilization, quality embryos, successful implantation, chemical pregnancy, clinical pregnancy and live birth did not exhibit remarkable difference between patients with higher and lower serum progesterone level at multiple thresholds on the day of hCG administration in the 786 cycles (P >0.05). However, when the thresholds of serum progesterone were at 8.5 and 9.0 nmol/L, early abortion rates of 27.3% (3/11) and 3/7 in higher progesterone group were significantly higher than 8.8% (26/297) and 8.6% (26/301) in lower progesterone group (P<0.05). And the total abortion rates of 3/7 in higher progesterone group were significantly higher than 11.0% (34/301) in lower progesterone group when the thresholds of serum progesterone were 9.0 nmol/L (P<0.05). Conclusions This study did not prove the correlationship between progesterone level at the clay with hCG administration and the probability of clinical pregnancy or live birth. However, early abortion rates or the total abortion rates were associated with higher progesterone level when the thresholds of serum progesterone were at 8.5 nmol/L or 9.0 nmoL/L.
