Objective To investigate the possible mechanisms of ox-LDL on vascular smooth muscle cells (VSMC) with and without exogenous zinc finger protein A20 gene. Methods VSMC were trans-fected with plamid containing A20 gene and incubated with ox-LDL. TLR4 and LOX-1 mRNA expression were measured by RT-PCR. Results After VSMC incubated with ox-LDL, the expression of LOX-1 and TLR-4 mRNA reached a higher level. However, when VSMC were transfected with plasmid containing A20 gene, the NF-kB nuclear translocation and the ability of migration reduced to normal level. Conclusions ox-LDL can significantly activate NF-kB signaling system and enhance migration in VSMC. The activation may induce the inflammatory response in arterial wall, the migration of VSMC to the intima, and triggering the process of atherosclerosis. Transfecting plasmid containing A20 gene significantly inhibited the activation of NF-kB and the ability of migration of VSMC. A20 effects might be through inhibiting NF-kB signaling. Meanwhile, A20 blocked the development of atherosclerosis.

Objective To know the distribution of arsenic and trace elements in drinking water in the endemic arsenism areas in Shanyin County, Shanxi Province. Methods Drinking water samples were collected from the chronic endemic arsenic poisoning areas of Silizhuang and Shanghexi, Shanyin County, Shanxi Province and HPLC-HG-AFS system was used to analyze the arsenic contents, valence and speciation. The trace elements were determined by ICP-MS. The data were analyzed by SPSS13.0 for windows. Results A total of 63 drinking water samples were determined, 39.68% of them exceeded the standard limit of arsenic level, inorganic arsenic was the main arsenical in drinking water, iAs3+/(iAs3++iAs5+) ratio was 56.17% in the water sample (arsenic was higher than 50 ?g/L) . The contents of Fe, Mn, Hg, Se and Pb in part of drinking water samples exceed the standard limits. No significant difference was seen between the arsenic results determined by HPLC-HG-AFS and ICP-MS. Conclusion Arsenic contamination of drinking water in Shanyin County, Shanxi Province is severe. The most frequently seen arsenic valence state in drinking water is iAs3+. Some trace elements in part of drinking water samples exceed the standard limits, this may aggravate arsenic poisoning.

Objective To establish a new multiplex-PCR assay to improve the detection rate of mutations in the DMD gene in Chinese patients. Methods A retrospective review of DMD deletion spectrum of 355 DMD patients with deletions all over the gene was performed. All deletions were confirmed by " one-step approach" diagnostic procedure and MLPA analysis. The exons with high frequency of mutations were identified to constitute the amplification system and the PCR conditions were optimized. Results Two new multiplex-PCR assays were established. Assay one was used to detect 10 exons including exon 5, 8, 17, 44, 45, 47, 49, 50, 51 and 52 of DMD gene, in two PCR sets. The theoretical detection rate would be 92% (326/355). Assay two was used to detect 5 exons including exon 12, 19, 35, 43 and 54, which could be used to screen additional 5% (17/355) deletion cases. The method was validated in other 22 DMD patients. Multiplex-PCR results were completely identical to the MLPA results in all 22 DMD patients. Conclusions The two multiplex-PCR assays were established based on the analysis of 355 Chinese DMD patients with gene deletions. It is believed that the new approach would be more applicable for deletion detection on the Chinese DMD patients since the DMD cases involved were from the whole country.

OBJECTIVETo observe the intervention effect of electroacupuncture (EA) at "Weizhong" (BL 40) on rats with bupivacaine-induced multifidus muscle injury, so as to explore the action mechanism.

METHODSA total of 72 rats were randomly divided into a control group, a model group, a Weizhong group and a Shenshu group, 18 rats in each group. Each group was again randomly divided into a 4-day subgroup, a 7-day subgroup and a 14-day subgroup, 6 rats in each subgroup. Rats in the model group, Weizhong group and Shenshu group were treated with intramuscular injection of 0.5% bupivacaine (BPVC) to establish the model of multifidus muscle injury. Rats in the Weizhong group and Shenshu group were treated with EA at "Weizhong" (BL 40) and "Shenshu" (BL 23), 20 min per treatment, once a day. Each subgroup was treated for 4 days, 7 days and 14 days respectively. Rats in the control group and model group were treated with immobilization. The morphology and cross sectional area (CSA) changes of multifidus with HE and Masson staining at different time points were observed; the expression of insulin like growth factor 1 (IGF-1) and myogenic differentiation antigen (MyoD) was measured by immunohistochemical method.

RESULTSAfter the modeling, there were significant morphology changes of multifidus at different time points, which was not fully recovered after 14 days. The morphological observation in the Weizhong group and Shenshu group was superior to that in the model group. At 7th day, the CSA in the Weizhong group was higher than that in the model group (P < 0.05); at 14th day, the CSA in the Weizhong group and Shenshu group was higher than that in the model group (P < 0.01, P < 0.05). At 4th day and 7th day, the expression of IGF-1 in the model group was higher than that in the control group (both P < 0.01); at 4th day, that in the Weizhong group was higher than that in the model group (P < 0.01), and that in the Weizhong group was higher than that in the Shenshu group (P < 0.05), and that in the Shenshu group was as higher than that in the model group (P < 0.05); at 14th day, that in the Shenshu group was higher than that in the model and Weizhong group (P < 0.01). At 4th day, the expression of MyoD in the Weizhong group and Shenshu group was higher than that in the model group (P < 0.01), which was more significant in the Weizhong group (P < 0.01).

CONCLUSIONElectroacupuncture at "Weizhong" (BL 40) and "Shenshu" (BL 23) can both promote the regeneration of multifidus muscle injury. EA at "Weizhong" (BL 40) has a better effect at early phase, which may be related to the up-regulation of IGF-1 and MyoD and the completion of the proliferation of myoblast in advance.

Objective To investigate the efficacy and safety of oxycodone hydrochloride controlled-release tablets combined with gabapentin in the treatment of painful diabetic neuropathy.Methods Eighty patients with painful diabetic neuropathy were divided into group A and group B with 40 cases each by random digits table.Patients of group A received simple oxycodone hydrochloride controlled-release tablets,while patients of group B received oxycodone combined with gabapentin.The intensity of pain, oxycodone dosage, quality of life and adverse effect in two groups was observed and compared.Results The pain was obviously relieved in two groups, and the effective analgesic rate at 21-28 d after treatment in group B was superior to group A[95.0% (38/40) vs.62.5% (25/40)], there was significant difference between two groups (P＜0.05).Numerical rating scale NRS score at 28 d after treatment in group B and group A was 1.2 ± 0.3 and 2.8 ± 0.5 respectively,and there was significant difference between two groups (P＜ 0.01 );the oxycodone dosage at 28 d after treatment in group B was lower than that in group A[(32.2 ± 4.3 )mg vs.(40.3±5.5 ) mg], and there was significant difference between two groups (P ＜ 0.05 ); the quality of life in group B was superior to group A, and there was significant difference between two groups (P ＜ 0.05 or ＜ 0.01 );the incidence of dizzy at 7, 14 d after treatment in group B was higher than that in group A[35.0% (14/40) vs.15.0% (6/40) and 30.0% (12/40) vs.10.0% (4/40)],and there was significant difference between two groups (P ＜ 0.05 ).Conclusion Oxycodon hydrochloride controlled-release tablets combined with gabapentin is effective and safe for the management of painful diabetic neuropathy.

Objective To investigate the effect of CHRNA1 genetic polymorphism on neuromuscular blockade induced with rocuronium. Methods Ninety-five ASA Ⅰ or Ⅱ patients of both sexes (age 18-64 yr,BMI 18-25 kg/m2 ) undergoing elective intra-abdominal surgery under general anesthesia were divided into 3 groups according to their genotypes: group Ⅰ AA ( n = 71 ); group Ⅱ AG ( n = 19) and group Ⅲ GG ( n = 5). ECG,BP, HR and SpO2 were continuously monitored during anesthesia. Neuromuscular function was assessed by response of adductor pollicis muscle to stimulation of the ulnar nerve using TOF-Watch SX monitor. Genomic DNA was extracted by using proteinase K digestion followed by a salting out prosedure. rs16862847 polymorphisms were analyzed by PCR-restriction fragment length polymorphism analysis and direct sequence analysis. Anesthesia was induced with fentanyl 4 μg/kg and propofol 2 mg/kg. Rocuronium 0.2 mg/kg was injected iv as soon as the patients lost consciousness. Results The twitch height of adductor pollicis muscle was significantly decreased in group AG and GG as compared with group AA ( P ＜ 0.05). There was no significant difference between group AG and GG.Conclusion CHRNA1 genetic polymorphism can influence the neuromuscular blockade induced with rocuronium,indicating that the genetic factor is one of the reasons contributing to the individual variation in neuromuscular blockade induced with muscle relaxants in patients.

Objective To evaluate the effect of transforming growth factor-β (TGF-β) on the expressions of epithelial-to-mesenchymal transition (EMT)-related molecules in human A431 epidermal squamous cell carcinoma cells.Methods Cultured A431 cells were classified into two groups:TGF-β group treated with TGF-β of 7.5 μg/L for 72 hours,and control group remaining untreated.Subsequently,cell morphology was observed under an inverted microscope,and real time-PCR and Western blot were performed to quantify the mRNA and protein expressions of EMT-related molecules including E-cadherin,N-cadherin,vimentin and β-catenin respectively.Results After TGF-β treatment,the cells became dispersed and spindle in shape.The mRNA expression levels of E-cadherin,Ncadherin,vimentin,and β-catenin in TGF-β group were 0.317,2.475,11.340 and 2.615 folds those in the control group respectively.Western blot showed a marked increase in the expression of N-cadherin,vimentin,and β-catenin proteins but a notable decrease in that of E-cadherin in the TGF-β group compared with the control group.Conclusions TGF-β can induce EMT in A431 cells,and increased expression of TGF-β may contribute to the invasion and metastasis of SCC.

Objective To evaluate the factors influencing prognosis and to explore the pathological mechanism in which herpes simplex virus encephalitis(HSE) was one of the severe types of acute viral encephalitis in children and had poor prognosis.Methods Twenty-one children with HSE were diagnosed by the clinical syndrome of focal encephalitis and HSV DNA-PCR positive in cerebrospinal fluid(CSF) from Jan.2012 to Oct.2013,among whom,19 patients were treated with intravenous Acyclovir,30 mg/(kg · d) 48 hours after onset and were followed up for 6 to 24 months.Clinical data were collected including Glasgow Coma Score,the brain magnetic resonance imaging(MRI),and electroencephalography(EEG).All MRI examinations including plain scan and contrast enhancement were carried out at the beginning of admission and 1 month after the onset of symptoms.The clinical outcomes were divided into two levels accoming to the severity of the neurological deficit,then the data were analyzed by using Logistic regression and Fisher's exact probability method.The OR value was calculated.Results Eighteen children survived,of whom 5 cases had no neurological deficit(27.8％),3 cases were left with mild impairment(16.7％),and the above 8 cases were thought to have better outcome.Six cases had moderate impairment (33.3％) and 4 cases had severe impairment(22.2％) and 1 child died,and these 11 cases were thought to have worse outcome.Patients aged between 1 month and 10 years,average (2.03 ± 2.23) years old.The mean GCS score was (9.68 ± 2.65) scores,the GCS of the patients were more than 7except for one death child with 3 scores.The multiple factor analysis showed that EEG,age,GCS and the range and character in MRI were significantly correlative to the prognosis(P ＜ 0.05).The single factor analysis illustrated that age 1-4 years old(OR =30,95％ CI 2.066-366.510,P =0.002),GCS ≤ 10 scores(OR =27.518,95％ C1 2.066-366.510,P =0.004)and the wide necrosis existence involving diffuse white matter or deep nuclei of MRI findings (OR =12,95 ％ CI 1.294-111.323,P =0.017) indicated the worse outcome.Conclusions Age,GCS score,nature and damage degree of MRI lesions are the main important factors affecting the prognosis of children's HSE.HSE in children is apt to involve the cortex such as frontal lobe,parietal lobe even diffuse white matter or deep nuclei,which indicates the poor prognosis.
