High mobility group box l protein (HMGB1) is a highly conserved non-histone DNA binding protein,which is widely distributed in eukaryotic cells.HMGB1 is an important proinflammatory cytokine,involving in various pathological and physiological processes,such as inflammation,neurogenesis and angiogenesis.In the early stage of intracerebral hemorrhage,HMGB1 can induce secondary brain injury,such as inflammatory reaction,neuronal necrosis,and brain edema.However,in the late stage of intracerebral hemorrhage,HMGB1 can promote angiogenesis and neurogenesis,and thus improving neurological function.HMGB1 will become a novel therapeutic target for intracerebral hemorrhage in the future.

Epithelial-mesenchymal transition (EMT) is that cells undergo a switch from epithelial phenotype to mesenchymal phenotype.Recent researches show that EMT can affect the occurrence and development of gastric cancer through a variety of mechanisms and promote the migration and invasion of tumor cells.The process of EMT involves a number of signal transduction pathways,and is related to microRNAs,Helicobacter pylori,transcription factors and so on.EMT is expected to be a novel therapeutic target of gastric cancer.

The LHX3 and LHX4 LIM-homeodomain transcription factors play essential roles in pituitary gland.Nervous system developments play certain roles in some cancers,leukemia,and deafness disease.Mutations in the genes encoding these regulatory proteins are closely associated with combined hormone deficiency diseases in human and animal models,and related to nervous system defect,tumors,leukemia and deafness.Analysis of these diseases and the biochemical properties of the LHX3 and LHX4 protein will facilitate a better understanding of the pathogenesis of these diseases.LHX3 and LHX4 are reviewed in this paper.

The artificial urinary sphincter (AUS) has been used for the treatment of various incontinence due to intrinsic sphincter deficiency, and is considered as the gold standard treatment for incontinence after a prostatectomy. The long-term satisfaction rates exceed 80%, but almost a third of patients with AUS require revision surgery within 5 years. This paper reviewed the common complications of AUS implantation and the treatment.

ObjectiveTo evaluate the clinical efficacy of intravenous catheter in combination with ultraviolet radiation for postherpetic neuralgia (PHN).Methods96 patients with PHN were randonly divided into three groups.Intravenous catheter plus UVB radiation was given in the test group(32 patients).Intravenous catheter or UVB radiation was only given in two control groups (32 patients/group), respectively.ResultsThe total effective rate in the test group was 96.88％ (31/32) and the average onset time was 1.55 days.However,the total effective rate in two control groups was 81.25％ (26/32) and 68.75％ (22/32) ,and the average onset time was 2.48 days and 7.41days.There was a statistical difference observed in curative rate (x2 = 5.33,42.42, P ＜ 0.05 or P ＜ 0.01), the total effective rate(x2 =4.59,8.89,P＜0.05 or P＜0.01) and the average onset time(t =22.96,11.96,all P＜0.01)between the test group and two control groups.Moreove,there was also a statistical difference observed in curative rate (x2 = 22.44, P ＜ 0.001) and the average onset time (t = 29.30, P ＜ 0.01) between two control groups.ConclusionIntravenous catheter in combination with UVB radiation was much better than intravenous catheter or UVB radiation only in the treatment of PHN.

BACKGROUND: The determination of monoamine neurotransmitters and their metabolites is important in the experimental.research of Parkinson disease (PD) and experimental diagnosis of phaochromocytoma.OBJECTIVE: To develop a high performance liquid chromatography (HPLC) method for simultaneous and rapid determination of monoamine neurotransmitters and their metabolites which include epinephrine(E), norepinephrine(NE), dopamine(DA), 5'-hydroxytryptamine(5'-HT), 5-hydroxy3-indoleacetic acid(5-HIAA), homovanillic acid(HVA) and 3,4-dihydroxyphenylacetic acid(DOPAC).DESIGN: Case control observation and a randomized controlled animal experiment.SETTING: Department of Clinical Laboratory, Affiliated Hospital of Medical College, Qingdao University; Haiyang Branch, Affiliated Hospital of Medical College, Qingdao University.PARTICIPANTS: This experiment was carried out at Staff Room of Physiology, edical College, Qingdao University and Department of Clinical Laboratory, Affiliated Hospital of Medical College of Qingdao University from October to December 2003. ①Two patients with phaeochromocytoma were all confirmed by CT, MRI or pathologic section as well as physical sign. Twelve health volunteers were all university students and were excluded to suffer hypertension, endocrine system diseases and other diseases. ② Total 12 healthy female Wister rats weighed between 150 g to 180 g were chosen and randomly divided into control group and PD group with 6 rats in each.METHODS: The standard chromatograms of the standard solution of mixtures of seven substances (E, NE, DA, 5'-HT, 5-HIAA, HVA and DOPAC)were prepared and the precisions and recovery rates of the same samples were determined respectively. Urine samples of 24 hours obtained from 12 healthy volunteers and 2 patients with phaeochromocytoma were analyzed respectively by HPLC. The unilateral forebrain bundles in PD group were destroyed with 6-hydroxydopamine (6-OHDA) for monitoring release characteristics of monoamine neurotransmitters and their metabolites in healthy and marred caudate putamen nucleus striatum of normal and PD rats striatum.MAIN OUTCOME MEASURES: ①Determination of the precisions and recovery rates of monoamines. ②The contents of catecholamines in 24 hours urine of 12 health volunteers and 2 patients with phaeochromocytoma .③The release characteristics of monoamines and their metabolites in rats striatum. RESULTS: The results and analysis of catecholamines substances in 24hours urine were all obtained from 12 health volunteers and 2 patients with pheochromocytoma. There were no animals died in the experinment, and all of them were involved in the result analysis. ①There was a favorable linear relationship in the range of 2-1 000 μg/L for DA, E, NE and DOPAC, 10-1 000 μg/L for 5-HIAA, HVA and 5-HT for 30-1 000 μg/L with HPLC. The minimal detection limit of DA, E, NE and DOPAC was 2 μg/L, 5-HIAA 10 μg/L, HVA and 5-HT 30 μg/L. The coefficient of variation (CV) in the same batch was 3.0%-8.6%, and the CV in the different batchs was 3.8%-9.7%. The average rates of recovery of DA, NE, E and other 4 kinds of substances were 107.3%, 89.4%, 80.1% and 89.2%-95.7%, respectively.②The contents of CA in 24 hours urine of the 2 patients with phaeochromocytomas were higher than those of the 12 healthy volunteers. One of patient samples showed that E was mainly higher than that of control group. Other samples showed that NE was mainly higher than that of control group. Otherwise , E and NE were ten times higher than that of control group. ③The contents of DA and its metabolites such as DOPAC and HVA in intact sides of hemiparkinsonian rats had no significant changes ,while the contents of DA, DOPAC and HVA in lesion sides were significantly decreased compared with the controls (P ＜ 0.01 ).There were no significant changes in the contents of 5-HT and its metabolites 5-HIAA. ④The turnover rates of DA (DOPAC/DA and HVA/DA) in intact and lesion sides of hemiparkinsonian rats were all higher than those of the controls(P ＜ 0.05).CONCLUSION: The method we developed is suitable for the experimental research of normal and hemiparkinsonian rat models and for the diagnostic testing of phaeochromocytoma.

Objective To investigate the pharmacodynamics characteristics of continuously infused cisatracurium besylate during total intravenous anesthesia. Methods Sixty ASA Ⅰ - Ⅱ patients undergoing elective oromaxillo-facial region surgeon were randomly divided into 4 groups. 1.0, 2.0, 3.0 μg/ (kg · min ) of cisatracurium besylate was continuously infused differently in group Ⅰ, group Ⅱ and group Ⅲ, and 0.1 mg/kg of cisatracurinm besylate was injured interruptedly into group Ⅳ after anesthesia induction. Neuromuscular function was assessed using an accelerometer with train-of-four (TOF) stimulation, the maximum depression of T1and times to T1 recovered to 25%(the clinic time), 75%, 90%(the vivo time) were noted. The recovery index (time of T1 recovery from 25% to 75%) was also calculated. Results The drug consumptions of cisatracurium besylate in group Ⅰ and group Ⅱ were diminished than those in group Ⅲ and group Ⅳ [(59.1±9.6),(116.7±11.5)μg/kg vs (174.9±23.1), (177.2±20.4) μg/kg](P<0.01), and group Ⅲ and group Ⅳ were nearly (P>0.05 ). The maximum depression of T1, the clinic time and the vivo time in group Ⅰ, Ⅱ,Ⅲ were smaller than those in group Ⅳ [ ( 18.5±3.6)%, (6.4±2.7)%, 0 vs (25.0±0.0)% ] (P < 0.01 ), but there were. No significant differences in recovery index in 4 groups. The maximum depression was diminished (P< 0.01 ) and the clinic time and the vivo time were prolonged (P<0.05) with the inerease of the dosage of cisatracurium besylate in group Ⅰ, Ⅱ, Ⅲ. Conclusions With no cumulative effect, the duration of recovery of muscle relaxation is shortened and the recovery index of continuously infused eisatracurium besylate is prolonged. It indicates that the cisatracurium besylate is suitable for the continuously infusion for surgeon patients.

Purpose To study the effect and mechanism of miR-199a-5p on the invasion of breast cancer MDA-MB-231 cells. Meth-ods miR-199a-5p mimic was transfected into MDA-MB-231 cells. Influence of miR-199a-5p on the invasion of MDA-MB-231 cell was displayed by Transwell, the expression of epithelial-mesenchymal transition ( EMT) molecular markers ( E-cadherin, vimentin) regulated by miR-199a-5p was determined using immunofluorescence and Western blot. Western blot was employed to assess the levels of ERK5, pERK5, EGF and SP1 in MDA-MB-231 cells dealt with miR-199a-5p mimic and LNA-siRNA. Chromatin immunoprecipita-tion (CHIP) was applied for displaying the reaction of SP1 with ERK5 promoter. Results miR-199a-5p could inhibit the invasion of MDA-MB-231 cells, decrease the expression of vimentin and enhance E-cadherin. Meanwhile, miR-199a-5p decreased the expression of ERK5 and pERK5, the levels of EGF and SP1 were also downregulated. On the contrary, the levels of EGF, SP1, ERK5 and pERK5 were enhanced by employing LNA-siRNA targeting miR-199a-5p. SP1 could bind with ERK5 promoter. Conclusions miR-199a-5p could reduce the expression of ERK5 and pERK5 through regulating EGF and SP1, which functioning the inhibitory effect on invasion of MDA-MB-231 breast cancer cells.
