Objective To investigate the effects of transcranial electrotherapy stimulation (TES)on patients with generalized anxiety disorder (GAD). MethodsA total of 62 patients with GAD were randomly divided into two groups,the study group (treated with TES and venlafaxine) and the control group (treated with venlafaxine only).TES was administered 1 time per day for 14 days,while venlafaxine was administered with oral intake of 75-150mg/d for 4 weeks.The clinical effects were assessed by using Hamilton anxiety scale (HAMA).ResultsThere was no difference between the two groups in average HAMA total scores,psychic and somatic factor scores before the treatments (P ＞ 0.05).The effective rate of study group was significantly higher ( P ＜ 0.05 ) at the end of the 1 st week after treatment than,but similar at the end of the 2nd and 4th week after treatment (P ＞ 0.05 ) to that,of control group,with regard to HAMA total score and psychic factor score.With regard to the HAMA somatic factor score,the effective rate of study group was not significantly different from that of control group at the end of the 1st,2nd and 4th week after treatment (P ＞ 0.05).ConclusionTranscranial electric stimulation in conjunction with venlafaxine may improve the symptoms of anxiety of patients.

Newborn brain damage is the main cause of new-borns' death and disabilities.Current research difficulties lie in analyzing characteristics of cerebral injuries,making objective prognosis and early intervention,as well as analysis of therapeutic effects after recovery.Since subjects are not requested to complete complex tasks while doing resting state functional MRI (rs-fMRI) tests,rs-fMRI is reckoned to be suitable for neonatal brain function research.So far,most rs-fMRI reports regarding cerebral injury are for adults,with only a few have been done on neonates.Foreign research are mainly focused on new borns' brain development.If relevant rs-fMRI research can be done on newborn brain damage,it would be helpful to accurately evaluate structure and function of patients' brain tissue damage.Further research can provide more valuable information in clinics.

BACKGROUND:The morphological structure of nanofiber scaffold which fabricated by electrospinning technique is similar to the natural extracelular matrix, which provides a good microenvironment for cel growth and proliferation, and can also enhance cel adhesion, migration, proliferation and differentiation. OBJECTIVE: To observe the biocompatibility of double-layer poly(L-lactic acid) electrospun nanofiber scaffold and human periodontal ligament cels. METHODS: Electrospinning technique was used to prepare double layers poly(L-lactic acid) electrospun nanofiber scaffold. The toxicity of different concentrations of (100%, 75%, 50%, 25%) double-layer poly(L-lactic acid) electrospun nanofiber scaffold extracts to human periodontal ligament cels was evaluated by MTT assay. The double-layer poly(L-lactic acid) electrospun nanofiber scaffold was co-cultured with human periodontal ligament cels. The cel adhesive capacity in early stage was determined by MTT assay. The growth of cels on the scaffold was observed by scanning electron microscopy. RESULTS AND CONCLUSION: Different concentrations of double-layer poly(L-lactic acid) electrospun nanofiber scaffold extracts did not create any toxicity to human periodontal ligament cels. After co-culture for 2, 6, 24 hours, human periodontal ligament cels were poorly adherent onto the double-layer poly(L-lactic acid) electrospun nanofiber scaffold. After 7 days of co-culture, human periodontal ligament cels adhered wel on the loose surface of scaffold, maintained the original shape, stretched wel, and interconnected processes were observed; on the dense surface of the scaffold, multi-layer cels were observed. The cels showed fusiform or polygonal appearance and were connected together. These results demonstrate that the double-layer poly(L-lactic acid) electrospun nanofiber scaffold has good biocompatibility with human periodontal ligament cels.

Objective To observe the anesthesia and analgesia effect of ultrasound guided inter-scalene brachial plexus block (ISPSP)on upper extremity surgery.Methods Fifty-four patients (male 34 cases,female 20 cases,aged 37-73 years,ASA grade Ⅰ or Ⅱ)scheduled for elective upper limb surgery under ISPBP combined with general anesthesia were randomly assigned into two groups:magnesium sulfate group (group M,n =27)and control group (group N,n =27).0.5% ropivacaine 8ml (40 mg)+10% magnesium sulfate 2 ml (0.5 g)were used in group M ,0.5% ropivacaine 8 ml+ normal saline 2ml (40 mg)were used in group N.After the effects of ISBPB were confirmed,pa-tients were inserted laryngeal mask under intravenous induction.Anesthesia was maintained by inha-ling sevoflurane(MAC 0.8)during the operation.The onset time of sensory and motor block,duration of sensory and motor block,duration of analgesia,pain visual analogue digital score (VAS)4,8,12, 24 hours after operationand complications were recorded.Results Duration of sensory block and du-ration of analgesia of group M was significantly longer than those of group N (P <0.05).The patient`s VAS score of 8,12,24 hours after surgery in group M was significantly lower than that on group N (P <0.05).Onset time of sensory and motory block of both groups was similar.Conclusion 0.5%ropivacaine combined with magnesium sulfate in ultrasound-guided ISPBP can extend the duration of sensory block,reduce postoperative pain,as well as prolong analgesia time.
