Objective To detect the changes of serum complement 3(C_3) and C_4 in neonates with hypoxic-ischemic encephalopathy(HIE) and its effects on non-specific immunological function.Methods Sixty-seven neonates with HIE and 30 normal full-term infants were recruited in the study.According to characteristic of immunological function and severity of HIE,the neonates were divided into 1-3 day group(n=32)and 4-6 day group(n=35).In each group,it was divided into mild group and moderate-severe group.The complement in serum was detected by radial immunodiffusion assay with Behring Nephelometer 100 Analyzer.Results In 1-3 day group,levels of C_3,C_4 in serum were lower than those in control group(P

0.05).In 4-6 day group:percentages of CD3+ and CD4+ cells and ratio of CD4+/CD8+ in neonates with HIE were all obviously lower than those in control group(P0.05).The level of percentages of CD3+ and CD4+ cells and ratio of CD4+/CD8+ in 9 subjects with moderate-severe HIE were remarkably higher during recovery stage than those during acute stage(P

Objective: To observe the clinical effect of auricular point sticking therapy for cardiac syndrome X (CSX) in women. Methods: A total of 64 patients were randomized into two groups by the random number table, with 32 cases in each group. Patients in the control group received conventional treatment for angina, while patients in the treatment group received auricular point sticking therapy on the basis of conventional treatment. After 8 weeks of treatment, the levels of serum estradiol (E2), nitric oxide (NO) and endothelium-1 (ET-1) were compared to evaluate the therapeutic effect. Results: After 8 weeks of treatment, the total effective rate and markedly effective rate in the treatment group were significantly higher than those in the control group, and the between-group comparisons showed statistical significance (both P<0.05). After treatment, the scores of chest pain and tightness in the control group dropped significantly, and the intra-group comparisons showed statistical significance (both P<0.05); the scores of chest pain and tightness, palpitations, weakness and shortness of breath in the treatment group dropped significantly, and the intra-group comparisons showed statistical significance (all P<0.05); there were significant inter-group differences in the scores of chest pain and tightness. After treatment, the intra-group comparisons of E2, NO and ET-1 contents in the control group showed no statistical significance (all P>0.05), while the E2, NO and ET-1 contents in the treatment group changed significantly after treatment and were significantly different from those in the control group (all P<0.05). Conclusion: Auricular point sticking on the basis of conventional treatment was effective for CSX in women, and is worth clinical application.

AIM:To explore the effect of comprehensive therapy in the treatment of fungal corneal ulcer and clinical outcome.
METHODS:A total of 159 cases 159 eyes fungal corneal ulcer patients took comprehensive therapy of 10 measures, followed up more than 3mo to observe the treatment effect and the final visual acuity in our hospital for treatment.
RESULTS: The average hospitalization time of fungal corneal ulcer was(12. 11±5. 13) d. A total of 148 cases of 148 eyes were cured, and the cure rate was 93. 1%;improvement in 8 cases, accounted for 5. 0%; 3 cases were ineffective, accounted for 1. 9%. The final visual acuity of 89 eyes ≥0. 3, accounted for 56. 0%(89/159). The final visual acuity of 136 eyes ≥0. 1, accounting for 85. 5%(136/159), and accounting for 91. 9% in 148 cured patients.
CONCLUSION: The comprehensive therapy in the treatment of fungal corneal ulcer has higher cure rate and visual acuity.

OBJECTIVE To get knowledge of the drugs resistance change of Pseudomonas aeruginosa in intensive care unit (ICU) from 2001 to 2006, so as to offer the first-hand information to the clinical preventive and therapeutic countermeasures. METHODS The P. aeruginosa antimicrobial susceptibility tests to 15 commonly used antibiotics were performed from 2001 to 2006. RESULTS The most frequent isolates were P. aeruginosa, Klebsiella pneumoniae and Acinetobacter baumannii in 2001-2004. Staphylococcus aureus was more than A. baumannii in 2006, and became the major isolated pathogen in the sputum of the ICU patients. The multi-resistant P. aeruginosa increased yearly, and drugs susceptibility to carbapenem had decreased sharply in the past 6 years. CONCLUSIONS It was showed that P. aeruginosa is the major pathogen in the ICU, and the pathogens show the high drug resistance. Doctors should pay more attention to analyze the bacterial resistance profile in order to decrease the incidence of drug resistance and use the antibiotics properly.

The effects of subclinical epileptiform discharges (SEDs) on children with cerebral palsy cannot be ignored. Data from neurodevelopmental clinic studies showed that the overall incidence of SEDs in cerebral palsy was 18%～40%, with the highest in spastic hemiplegia and diplegia. The major pattern of SEDs was focal and multifocal, and was usually found in centro-temporal and parietal regions. The cortex impairment and other complications were risk factors related to SEDs in cerebral palsy. Paroxysmal or frequent long-time SEDs, with the Results of transient or chronic cognitive impairment, have been found to lead to subsequent death of cortical neurons of cerebral palsy patients thereby worsening their prognosis. Valproic acid (VPA), benzodiazepines (BZs) and lamotrigine (LTG) have a role in inhibiting SEDs, while adrenocorticotropic hormone (ACTH) and glucocorticoids have a great role in it.

Ten compounds were isolated from the artificially induced dragon's blood of Dracaena cambodiana by various column chromatographies on silica and sephadex LH-20 gel. Based on spectral analysis of NMR and MS, their structures were identified as 3, 4-dihydroxyallylbenzene (1), 3', 4', 5'-trimethoxycinnamylalcohol (2), pinoresinol (3), (2R)-7, 4'-dihydroxy-8-methylflavane (4), (2R)-7,4'-dihydroxy-5-methoxy-8-methylflavane(5),(2S)-7,3'-dihydroxy-4'-methoxy-8-methylflavane(6) ,(2S)-4',7-dihydroxy-6, 8-dimethylflavane(7), 4,2',4'-trihydroxychalcone(8), 4,4'-dihydroxy-2-methoxydihydrochalcon(9) and Cambodianin E (10). Antibacterial activity assay showed that compounds 1, 4 and 10 have inhibitory effect on Fusarium oxysporum f. sp. cuben, Fusarium oxysporum f. sp. niveum, Fusarium oxysporum f. sp. vasinfectum and Ralstonia solanacearum.

OBJECTIVETo study the cleavage activity on the HCV RNA of a chimeric recombinant of HCV specific ribozyme and U1 small nuclear RNA, which compartmentalizes within the nucleolus.

METHODSThe third stem-loop sequence of human U1 snRNA (position 95-116) within pBSIISK+ U1 was substituted by hammerhead ribozyme against HCV RNA by PCR and cloning methods, and the constructed plasmid was named pBSIISK+ (U1-Rz). Then the whole gene fragment of the chimeric ribozyme was cloned into a pGEM-T vector under the control of T7 promoter, and the constructed plasmid was named pGEM- (U1-Rz). The pGEM- (U1-Rz) and pGEM-Rz (containing the same ribozyme sequence as that in U1-Rz) transcripts as enzyme were transcribed in vitro. Also the (32)P-labeled pCMV/T7-NCRC luc (containing the gene sequence of the whole 5'-NCR and part core of HCV RNA) transcripts as target-RNAs were transcribed in vitro. The enzymes were incubated with the target RNAs under different conditions and autoradiographed after denaturing gel-electrophoresis.

RESULTSThe sequencing result showed that the construction of U1 snRNA chimeric ribozyme was correct. Compared with the ribozyme alone, both of them were active at 37 degree C and with Mg2+ (10 mmol/L) and TrisCl (10 mmol/L, pH7.9), and there was no remarkable difference between them. The cleavage activity of the chimeric ribozyme increased with the prolongation of reaction time and increment of enzyme concentration.

CONCLUSIONBoth ribozyme and U1 snRNA chimeric ribozyme exhibited specifically catalytic activity against HCV RNA in vitro. There was no remarkable difference between their cleavage efficiencies.
