40 rabbits are used to study the effects of phaco-emulsification and extracap-sular lens removal or; corneal endothelial cells and corneal thickness.With the specular microscope, the preoperative cell morphology, cell density and thickness of cornea are revealed. The endothelial cell counts decrease 16% (at central) and 14% (at the periphery) after the surgery with phaco-emulsification and 25% (central) and 22% (periphery) with extracapsular lens removal. Corneal thickness increases in both groups. Scanning electron microscopy shows some alterations in morphology of endothelial cell injury significantly different in the 2 groups. According to these results the causes of corneal thickness increasing and mechanism of endothelial cell injury are approached and a new procedure preventing the cell injury and decreasing cornea edema in both groups is designed.

Dendritic cells (DCs)can capture HIV from the mucosal site and carry it to the draining lymph nodes to promote CD4 + T cell infection.DC-SIGN(CD209)plays a vital role during this process. Heroin,methamphetamine and cocaine are the most abused drugs used by drug abusers,which can increase the opportunities of HIV infection.Drugs acting on the corresponding receptors activate the downstream signaling pathway and regulate the expression of DC-SIGN on the surface of DCs,weakening the inhibited effects of immune cells on HIV and promoting HIV infection in many aspects.Given the multiplex effects of drugs on immune function,this article reviews the relationship between abused drugs,DCs and HIV infection,particularly in the signal pathway on immune modulation.

BACKGROUND: The early symptoms of amyotrophic lateral sclerosis (ASL) are usually located at a certain part of the body, and are similar to the clinical manifestations of cervical spondylotic myelopathy (CSM). However, their treatment and prognosis differ greatly. Therefore, multiple-part electromyography and electroneurography possess an important value of reference, particularly electromyography of thoracic paraspinal muscles can be used as an objective parameter for differentiation between ASL and CSM.OBJECTIVE: To investigate the electrophysiological changes in ASL and CSM.DESIGN: A retrospective clinical analysis.SETTING: Neurological Department of Second Hospital Affiliated to Jiangxi Medical College.PARTICIPANTS: Totally 30 inpatients and outpatients with ASL and 30 patients with CSM were selected from the Neurological Department of the Second Hospital Affiliated to Jiangxi Medical College between December 2001 and November 2004.METHODS: Totally 30 inpatients and outpatients with ASL as well as 30 inpatients and outpatients with CSM were subjected to routine electromyographic and electroneurographic examination. Routine electromyography examining three limb muscles + sternocleidomastoid + thoracic paraspinal muscles intended to observe the spontaneous potential at resting stage, time limit and wave-amplitude of motor unit potential, and recruit-ment phase during energetic contraction. Electroneurography was used to detect motsr conduction velocity and sensory conduction velocity,as well as the terminal latency and wave-amplitude of motor evoked potential.limb muscles, sternocleidomastoid and thoracic paraspinal muscles in paASL and SCM.RESULTS: Data of all the 60 patients entered the final statistical analysis.in patients with ALS and CSM, and were more severe in the former. The abnormality rate of spontaneous potential of thoracic paraspinal muscles reached 93.3% (28/30) as compared to 3.3% (1/30) in patients with CSM (P ＜ 0.001). The average time limit and abnormal increment of wave amplitude of motor unit potential were significantly different in patients with conduction velocity: The decrease rate of motor evoked potential amplitude of complex muscles was obviously higher in ASL than in CSM (75.6% and 86.7%, ~=7.25, P ＜ 0.01). So was the decrease rate of motor conduction sory nerve conduction velocity: It was not affected either in ASL or CSM.ALS and CSM, but the abnormality rate of spontaneous potential of thorography indicates that nerve conduction velocity was not affected in both playing decreased conduction velocity and wave amplitude than those with CSM.

OBJECTIVE: To investigate the molecular mechanism of Huanglian Jiedu Decoction (HLJDD), a traditional Chinese compound herbal medicine, in treating type 2 diabetes mellitus (T2DM) by observing its effects on glucose transporter 4 (GLUT4) protein expression and translocation in adipose and skeletal muscle tissues of rats with T2DM. METHODS: T2DM was induced in rats by intravenous injection of a small dose of streptozotocin (STZ, 30 mg/kg) plus high fat and high caloric laboratory chow. Then animals were divided into untreated group, aspirin-treated group and HLJDD-treated group. Normal rats fed with common chow were designated as normal control group. Ten weeks later, the oral glucose tolerance test (OGTT) was performed in all animals, and the changes of murine body weight, fasting blood glucose (FBG), fasting serum insulin (FINS) and the expression of GLUT4 protein in skeletal muscle and adipose tissues before and after insulin treatment were routinely determined. RESULTS: Compared with the untreated group, the result of OGTT of HLJDD-treated group was improved. The levels of the body weight and FBG were decreased, while the GLUT4 protein expression and translocation were elevated obviously. CONCLUSION: It is suggested by the present results that the therapeutic effects of HLJDD on T2DM might be related to its ability of increasing GLUT4 protein expression and translocation in adipose and skeletal muscle tissues of T2DM rats.

Objective To evaluate quantification of metamorphopsia in eyes with idiopathic macular hole (IMH) before and after surgical treatment, and investigate its relationship between postoperative visual acuity, the macular hole index (MHI), and the macular hole prognostic factor (HPF). Methods Thirty eyes of 30 patients, who underwent successful vitrectomy and internal limiting membrane (ILM) peeling for IMH and were followed up more than 6 months, were included in the study. The uncorrected visual acuity of the fellow eyes was better than 20/25 and there was no metamorphopsia in that eye. The macular hole closure was confirmed by optical coherence tomography (OCT) scans. Metamorphopsia was evaluated by metamorphopsia-charts (M-chart). OCT, best corrected visual acuity (BCVA) and metamorphopsia were obtained before and after surgery. Vertical (MV) and horizontal (MH) metamorphopsia, macular hole index (MHI, the ratio of the height to the diameter of the base) , and macular hole prognostic factor (HPF,the ratio of the height to the minimum diameter) were measured. The metamorphopsia score was the average value of MV and MH. SPSS 16. 0 statistical analysis software was used for data analysis. Results Preoperative MV and MH were (1.82±0.04)° and (1.81±0.04)°, respectively. Six months after surgery,the MV and MH were (0.17±0.03)° and (0.11±0.03)° respectively. There was significant difference between pre- and post-operative metamorphopsia results (Z=-0.788, P＜0.05). The metamorphopsia score at 6 months after surgery were positively correlated with the value of the postoperative BCVA (LogMAR) (r=0.540, P=0.004) and negatively correlated with the values of preoperative MHI and HPF (r=-0.676,-0.518; P＜0.05). Conclusions Successful vitrectomy and ILM peeling can improve metamorphopsia of IMH. Postoperative metamorphopsia was correlated with the postoperative BCVA and the preoperative macular hole contour.

Objective To compare CT perfusion changes of patients 1 month after living liver transplantation with healthy volunteers. Methods Twenty perioperative patients without complications and 25 healthy volunteers underwent dynamic multi-slice CT scan. On each targeted slice, liver was divided into 3 regions of interest (ROI) according to hepatic venous drainage, i.e. anterior segment area drained by middle hepatic veins (MHV) which was most likely congested, risk area drained by both MHV and RHV which was posterior to anterior segment, reference area drained by RHV. Perfusion parameters and relative perfusion difference were calculated.Results The relative perfusion differences of anterior segment and risk area in study group were as follows: BF 44.56±43.19 vs 25.41±27.49 ［ml/(min〖DK〗·100 g)］; BV 3.91±2.45 vs 2.15±1.86(ml/100 g); PVP 41.50±39.15 vs 22.66±23.82 ［ml/(min·100 g)］. Significant differences of RPDs of BF, BV and PVP were found in anterior segment (P<0.0001) and risk area (P＜0.01) compared with control group.Conclusion In perioperative period, there are hemodynamic differences in hepatic segments drained by RHV and MHV. BF, BV, PVP of anterior segment decreases obviously.

Objective To evaluate metamorphopsia and vision-related quality of life (VRQoL) and its influencing factor after vitrectomy for idiopathic macular hole (IMH).Methods This is a prospective and nonrandomized clinical cohort study.Thirty eyes of 30 IMH patients who received vitrectomy and inner limited membrane (ILM) peeling were included.The best-corrected visual acuity (BCVA),medical refraction test and optical coherence tomography (OCT) were performed.BCVA was recorded as logarithm of the minimum angle of resolution (logMAR).The macular hole index (MHI) was measured using OCT.The average logMAR BCVA and MHI in suffering eyes at baseline were 1.02± 0.07 and 0.47 ± 0.02,respectively.The uncorrected visual acuity of the fellow eyes was less than 0.1.Follow-up period was longer than 6 months.At 6 months after surgery,the central retinal thickness (CRT) was measured by OCT;vertical and horizontal metamorphopsia were measured by metamorphopsia charts;VRQoL was evaluated by Chinese VRQoL-25.Spearman correlation analysis was performed to analyze the relationship of VRQoL and postoperative BCVA,metamorphopsia and preoperative MHI.Results At 6 months after surgery,macular hole closure was confirmed by OCT in all patients.The vertical and horizontal metamorphopsia were (0.17± 0.03)° and (0.11 ± 0.03)°,respectively.The VRQoL-25 composite score was 79.81 ± 1.29.The average BCVA was 0.59±0.05.The average CRT was (155.10± 6.27) μm.The postoperative VRQoL was positive correlated with preoperative MHI (r=0.491,P=0.002),and negative correlated with preoperative BCVA (r=-0.445,P=0.014),postoperative BCVA (r=-0.530,P=0.003) and postoperative metamorphopsia (r=-0.532,P=0.006),but not correlated with the postoperative CRT (r=0.231,P＞0.05).Conclusions IMH patients improved their visual acuity after surgery,but still have metamorphopsia.VRQoL was negative correlated with metamorphopsia,positive correlated with preoperative MHI.
