Objective To explore the clinical efficacy of intensive pulsed light(IPL) on body hair removal.(Methods A) total of 172 patients who suffered from heavy body hairs were treated by IPL since April 2002.It took 3 to 5 procedures,with the interval of one month. Results After treatment,80 patients(47%) were cured,42(24%) improved,and 50(29%) had no effect. Conclusion The intensive pulsed light system is safe and efficient in hair removal.

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

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.

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.

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.

Human immunodeficiency virus type 1 (HIV-1) is the causative agent of acquired immunodeficiency disease syndrome (AIDS). After over 26 years of efforts, there is still not a therapeutic cure or an effective vaccine against HIV/AIDS. The clinical management of HIV-1 infected people largely relies on antiretroviral therapy (ART). Although highly active antiretroviral therapy (HAART) has provided an effective way to treat AIDS patients, the huge burden of ART in developing countries, together with the increasing incidence of drug resistant viruses among treated people, calls for continuous efforts for the development of anti-HIV-1 drugs. Currently, four classes of over 30 licensed antiretrovirals (ARVs) and combination regimens of these ARVs are in use clinically including: reverse transcriptase inhibitors (RTIs) (e.g. nucleoside reverse transcriptase inhibitors, NRTIs; and non-nucleoside reverse transcriptase inhibitors, NNRTIs), protease inhibitors (PIs), integrase inhibitors and entry inhibitors (e.g. fusion inhibitors and CCR5 antagonists). Here, we intend to provide updated information of currently available antiretroviral drugs for ART to promote the development of novel anti-HIV-1 drugs.

Lipid metabolism disorder is an important risk factor to obesity, hyperlipidemia and type 2 diabetes as well as other chronic metabolic disease. It is also a key target in preventing metabolic syndrome, chronic disease prevention. Plant polyphenol plays an important role in maintaining or improving lipid profile in a variety of ways. including regulating cholesterol absorption, inhibiting synthesis and secretion of triglyceride, and lowering plasma low density lipoprotein oxidation, etc. The purpose of this article is to review the lipid regulation effects of plant polyphenols and its related mechanisms.
