Objective To investigate the effects of intense pulsed light(IPL) on the collagen metabolism in human fibroblasts.Methods The callan foreskin fibroblasts were cultured and treated with different wave length and designed dose of IPL irradiation(590-1 200 nm,and 29 J/cm2),while 10 without IPL irradiation as controls.By culturing 1,12,24 and 48 h after the irradiation,the synthesis of collagen was measured by 3H-proline incorporation determination. Results The synthesis of collagen activity increased significantly(P

ObjectiveTo observe the effect of Nimodipine on the hemorrheology and brainstem auditory evoked potentials (BAEP) in the patients with vertebrobasilar insufficiency (VBI) and to explore the mechanism.Methods50 cases with VBI were divided into Nimodipine group (25 cases) and routine therapy group (25 cases). The hemorrheology and BAEP were measured before the treatment and 1 month later.ResultsThe blood viscosity,including the whole blood viscosity shear value, plasma viscosity and blood fat of patients with VBI was increased. The total abnormity rate of BAEP was 76%. The main abnormity was brainstem type. The hemorrheology and the function of nerve conduction were improved distinctly (P<0.05) after treatment. Compared with the routine therapy group, the level of plasma viscosity was decreased markedly (P<0.05) in Nimodipine group, and peak latency of V wave, interpeak latency of III-V and I-V were also improved significantly (P<0.05).Conclusions Nimodipine can improve the hemorrheology and the function of nerve conduction in patients with VBI.

Objective: To objectively evaluate the short-term and long-term efficacies of arthrolysis under brachial plexus anesthesia in treating adhesive capsulitis of the shoulder (ACS). Methods: One hundred patients diagnosed with ACS were divided into two groups using the random number method. The two groups both received same active rehabilitation exercises. Besides, 55 cases in the treatment group were given one session of arthrolysis under brachial plexus anesthesia, and 45 cases in the control group were given tuina treatment. Changes in the visual analog scale (VAS) score, Melle score and pressure pain index were observed 1 month and 3 months after treatment. The therapeutic efficacies were also compared. Results: The total effective rate was 96.4％ at the 1-month follow-up and 96.4％ at the 3-month follow-up in the treatment group. The total effective rate was 33.3％ at the 1-month follow-up and 28.9％ at the 3-month follow-up in the control group. There were significant differences between the two groups comparing the total effective rate at the two time points (both P<0.05). The scores of VAS, Melle and pressure pain were significantly different at the 1-month and 3-month follow-ups from those before treatment in the treatment group (all P<0.05); the three scores did not show significant differences at the 1-month and 3-month follow-ups compared with those before treatment in the control group (all P>0.05). Conclusion: Based on the active rehabilitation exercises, one session of arthrolysis under brachial plexus anesthesia can release the adhesion and restore the range of motion and function of shoulder joint in ACS patients. It is superior to rehabilitation exercises plus tuina treatment comparing both short-term and long-term efficacies.

Aminoacyl-tRNA syntheses (AARS) can catalyze the adenosine triphosphate (ATP)-dependent acylation of their cognate tRNA(s) with a specific amino acid. They can be seen as an index to reflect the energy metabolic rate of ischemic brain cells in ischemic penumbra. This study examined the relationship between arginyl-tRNA synthetase (ArgRS), one of the AARS, and cerebral ischemia in rats. The model of middle cerebral artery occlusion (MCAO) was established in rats. The expression levels of ArgRS protein and mRNA were detected in rat brain tissues at different time points following MCAO by Western blotting and RT-PCR, respectively. The results showed that the MCAO model was successfully established. Western blotting and RT-PCR analysis revealed that the ArgRS protein and mRNA were expressed in brain cells in both ischemic and normal penumbra tissues. The expression levels of ArgRS protein and mRNA peaked at 6 h after MCAO and decreased gradually. At 24 h, the expression levels of ArgRs protein and mRNA in ischemic penumbral tissues were lower than those in normal tissues. The expression levels of ArgRS mRNA and protein in ischemic penumbra varied with ischemic time, suggesting that the energy metabolism of brain cells in penumbra changed dynamically after ischemia to ensure the endogenous self-protection of the body. The brain oxygen supply should be improved as soon as possible, especially within 6-12 h after ischemia, so as to meet the demand for energy metabolism in ischemic penumbra and make sure the cell structure remains stable.

ATM: To define the causes of corneal endothelial cell damage, to investigate the preventive methods, and to observe the variety of corneal endothelial cell in glaucoma using confocal microscope.
METHODS: Totally, 143 eyes of 97 patients with different types of glaucoma, and matched normal people were 20 cases, all 40 eyes. The cell density, cell area and cell variable coefficient were measured used confocal microscope. These indicatives of every kind of glaucoma were compared.
RESULTS: The corneal endothelial cell density of normal group was 2 893. 88±255. 026/mm2 , the group of acute angle-closure glaucoma ( AACG ) was 1 674. 11±683.95/mm2 , and the group of open angle glaucoma (OAG) was 2687. 22±391. 87/mm2, the group of chronic angle-closure glaucoma (CACG) was 2706. 97±351. 27/mm2. In all index the average cell density of corneal endothelial and the average area have statistical significance ( F =62.950, 8. 795;P=0. 000), especially the group of AACG.CONCLUSION: The index of corneal endothelial cell in AACG is lower than that of normal. All index in OAG and CACG is difference with that of normal, but the difference has no statistical significance. And the dominant factor of damaged corneal endothelial is the time of intraocular hypertension.

Objective To investigate the correlation between the angiotensin-converting enzyme(ACE)gene insertion/deletion(I/D)polymorphism and cerebrovascular diseases in Naxi population in Lijiang,Yunnan province.Methods Fifty-eight Naxi patients with cerebral infarction,32 Naxi patients with intracerebral hemorrhage,and 50 sex- and age-matched Naxi healthy controls were recruited.Polymerase chain reaction-restricted fragments length polymorphism was used to detect the ACE gene polymorphism and perform bidirectional sequencing Results The DD genotype and the D allele frequency in the cerebral infarction group were significantly higher than those in the healthy control group(32.8% vs.16.0%,P = 0.045 and 54.3% vs.39.0%,P =0.025);while there were no significant differences in the DD genotype and the D allele frequency between the intracerebral hemorrhage group and the control group.The different types of cerebral infarction carried different allele frequencies,they were in order of cerebral embolism ＜ cerebral thrombosis ＜ lacunar infarction.The DD genotype in patients with lacunar infarction(40.0% vs.30.0%,P = 0.481 )and the D allele frequencies(63.3% vs.51.2%,P =0.257)were all higher than those in patients with cerebral thrombosis,but there were no significant differences.Conclusions The ACE DD genotype carriers were susceptible to cerebral infarction in Naxi poulation in Yunan province.

OBJECTIVETo demonstrate the possibility of high-level expression of bioactive human beta-defensin-2 (hBD2) in E.coli, and to purify the recombinant hBD2.

METHODSDNA fragment containing mature hBD2 coding region (smhBD2-cDNA) was amplified by PCR, multiple copies of smhBD2-cDNA were linked using Bgl II and BamH I enzymes, pET32-nsmHBD2-cDNA with 1, 2, 4, or 8 copies of smhBD2-cDNA was constructed. The soluble and insoluble hBD2 proteins were separated and analyzed by SDS-PAGE analysis. The soluble protein underwent a separation process containing affinity chromatography, enterokinase digestion and ion exchange chromatography to get the recombinant hBD2 peptide. The bioactivity of recombinant hBD2 was examined by bacteria-inhibition tests in liquid culture.

RESULTThe plasmids pET32-nsmHBD2-cDNA with 1, 2, 4 copies of smhBD2-cDNA were constructed and the expressed soluble protein accounted for 52 %, 48 %, and 31 % respectively. The plasmids with 8 copies expressed mainly insoluble protein with few in soluble form. The growth of E.coli K12D31 was dramatically suppressed with a inhibition rate of 90 %, when the final concentration of recombinant hBD2 reached between 0.4 to 0.5 mug/ml.

CONCLUSIONFusion expression of human beta-defensin-2 with multiple joined genes in E.coli could increase the expression of hBD2.
