Objective T o explore the com position characteristic of event related potential (E R P ) in dif-ferent visual acuity levels, and to provide theoretical basis for the objective assessm ent of visual acuity. Methods M onocular stim ulus w as perform ed on 16 selected subjects. T he subjects w ere required to look straight at the screen ahead and count the am ount of stim uli from different directions. T he pictures of optotype stim ulus w hich corresponding to three different visual acuity levels w ere show ed in the center of the screen. The ERP results w ere recorded separately. Results (1) The P1 am plitudes of m atch stim uli recorded under the supra-threshold visual acuity level w ere higher than that of m atch stim uli recorded under the threshold and sub-threshold visual acuity levels. T here w as no significant difference betw een the P 1 am plitudes of m atch stim uli recorded under the threshold and sub-threshold visual acuity levels. T he tendency of conflict stim uli w as sim ilar to that of m atch stim uli under three visual acuity levels. (2) In the 340-500 m s post-stim ulus range, P 300 com ponent w as found under supra-threshold and threshold visual acuity levels; no P 300 com ponent w as found in corresponding tim e w indow under sub-threshold visual acuity. T he differences of P 300 am plitudes am ong three visual acuity levels w ere statistically significant. T he am plitudes from high to low w ere the supra-threshold, threshold and sub-threshold visual acuity levels. Conclusion E R P can be a potential new m ethod for the objective assessm ent of visual acuity in forensic m edicine.

OBJECTIVE:To excavate and evaluate the security alert signals of linezolid after marketing,and to provide refer-ence for rational drug use in clinic. METHODS:The reporting odds ratio(ROR)method was used to excavate the security alert signals from the adverse drug events(ADE)data in the OpenFDA platform of FDA during second quarter of 2004-2016. The low-er limit of 95%CI >1 was regarded as suggestive of ADE alert signal. RESULTS:A total of 6828534 reports were extracted, among which there were 7224 reports mainly induced by linezolid. Top 10 ADE reports were thrombocytopenia,drug interac-tion,thrombocytopenia,nausea,anaemia,serotonin syndrome,diarrhoea,pyrexia,drug ineffective,vomiting. After the detec-tion of top 200 ADE reports by ROR method,120 signals related to 18 system organ class(SOC)were identified. Top 5 ADE sig-nals in turn by SOC were medical examination,nervous system disorders,blood and lymphatic system disorders,metabolism and nutrition disorders,cardiac disorders. The high risk signals with clinical reference value included 42 cases of optic neuropathy (ROR=56.33),350 cases of serotonin syndrome(ROR=52.86),162 cases of lactic acidosis(ROR=18.30),31 cases of endo-carditis (ROR=15.38),566 cases of thrombocytopenia (ROR=14.29),122 cases of bone marrow failure (ROR=14.20),261 cases of panhematopenia (ROR=11.92),86 cases of disseminated intravascular coagulation (ROR=10.91),58 cases of toxic epidermal necrolysis(ROR=9.06),etc. As for ADE reports,male was slightly higher than female,and the patients in age group of ≥45 reported evidently more compared to younger age group. CONCLUSIONS:By detecting and evaluating alert signals of li-nezolid through OpenFDA platform,we could effectively lay the foundation for further research of pharmacovigilance.

Objective T o study the effect of different attentional conditions on the event-related potential (E R P ) com ponents generated by the visual inform ation stim uli related to visual acuity, and provide a theoretical reference for clinical forensic visual objective evaluation. Methods W ith visual acuity opto-types as norm al form of visual inform ation stim uli, 15 volunteers as study subjects w ere supposed to ac-count the visual acuity optotypes under the attentional condition of visual stim uli. Furtherm ore, the sub-jects w ere required to listen to the storytelling carefully under the non-attentional condition of visual stim uli, and after the exam ination, they needed to answ er the story-related questions. A ll the E E G re-sults of tw o different attentional conditions from the subjects w ere recorded by 32 channel E R P system . Results U nder tw o attentional conditions, P 1 and P 300 com ponents w ere evoked by the visual acuity opto-types on supra-threshold and threshold visual acuity levels, w hile only P 1 com ponent w ere evoked by the visual acuity optotypes on sub-threshold levels. In the E R P w aveform s evoked by the visual acuity optotypes on supra-threshold, P 1 and P 300 am plitudes under attentional condition w ere larger than that un-der non-attentional condition. Conclusion A ttentional conditions can influence the detection of visual acuity. P 300 com ponent can be used to distinguish the visual acuity levels w ith supra-threshold and sub-threshold under non-attentional condition.

OBJECTIVETo compare the clinical efficacy on upper limb motor impairment in stroke between the interactive dynamic scalp acupuncture therapy and the traditional scalp acupuncture therapy.
METHODSThe randomized controlled trial and MINIMIZE layering randomization software were adopted. Seventy patients of upper limb with III to V grade in Brunnstrom scale after stroke were randomized into an interactive dynamic scalp acupuncture group and a traditional scalp acupuncture group, 35 cases in each one. In the interactive dynamic scalp acupuncture group, the middle 2/5 of Dingnieqianxiexian (anterior oblique line of vertex-temporal), the middle 2/5 of Dingniehouxiexian (posterior oblique line of vertex-temporal) and Dingpangerxian (lateral line 2 of vertex) on the affected side were selected as the stimulation areas. Additionally, the rehabilitation training was applied during scalp acupuncture treatment. In the traditional scalp acupuncture group, the scalp stimulation areas were same as the interactive dynamic scalp acupuncture group. But the rehabilitation training was applied separately. The rehabilitation training was applied in the morning and the scalp acupuncture was done in the afternoon. The results in Fugl-Meyer for the upper limb motor function (U-FMA), the Wolf motor function measure scale (WM- FT) and the modified Barthel index in the two groups were compared between the two groups before treatment and in 1 and 2 months of treatment, respectively.
RESULTSAfter treatment, the U-FMA score, WMFT score and the score of the modified Barthel index were all apparently improved as compared with those before treatment (all P < 0.01). The improvement in the U-FMA score after treatment in the interactive dynamic scalp acupuncture group was better than that in the traditional scalp acupuncture group (P < 0.05). For the patients of IV to V grade in Brunnstrom scale, WMFT score in 2 months of treatment and the score of Barthel index after treatment in the interactive dynamic scalp acupuncture group were improved apparently as compared with those in the traditional scalp acupuncture group (P < 0.05, P < 0.01). But, for the patients of III grade in Brunnstrom scale, WMFT score and the score of Barthel index after treatment in the interactive dynamic scalp acupuncture group were not different significantly as compared with those in the traditional scalp acupuncture group (both P > 0.05).
CONCLUSIONFor the patients of IV to V grade in Brunnstrom scale in stroke, the interactive dynamic scalp acupuncture therapy achieves the superior improvements of the upper limb motor function and the activity of daily life as compared with the traditional scalp acupuncture therapy, and the longer the treatment lasts, the more apparent the improvements are. For the patients of III grade in Brunnstrom scale, the interactive dynamic scalp acupuncture therapy achieves the similar improvement in the upper limb motor impairment as compared with the traditional scalp acupuncture therapy.

Aim To explore the protective effects of lithium chloride ( LiCl ) on neurous injuries and phos-phorylation of tau protein at serine262 induced by okada-ic acid( OA) . Methods The neuroblastoma SK-N-SH cells were differentiated by all-trans-retinoic acid ( AT-RA) . The differentiated SK-N-SH cells were treated with OA to establish the Alzheimer′s disease cellular model. SK-N-SH cells′ viability and proliferation were measured by SRB test. Giemsa staining was used to observe cell morphology. The neurite length of SK-N-SH cells was measured by Image-Proplus software. Syn-aptophysin and phosphorylated tau protein at serine262 expression levels were tested by Western blot. Results The SK-N-SH cells which were treated with 10 μmol ·L-1 ATRA for 7 days displayed mature neuronal fea-tures. The synaptic length of SK-N-SH cells became longer. And the levels of serine262 phospho-tau was sig-nificantly elevated. 20~100 nmol·L-1 OA effectively inhibited the viability of differentiated SK-N-SH cells in a concentration-dependent manner and in a time-de-pendent manner. The OA treatment induced obvious synaptic atrophy in differentiated SK-N-SH cells. And the phosphorylation level of tau protein serine262 also greatly increased. The pretreatment with 10 mmol · L-1 LiCl significantly ameliorated the synaptic atrophy, the decrease of synaptophysin expression and the in-crease of tau phosphorylation at serine262 induced by OA in differentiated SK-N-SH cells. Conclusion LiCl could effectively inhibit OA-induced synaptic atro-phy in differentiated SK-N-SH cells, and it could also result in the increase of synaptophysin expression and the decrease of the phosphorylation of tau protein at serine262 .

OBJECTIVE:To investigate the general regularity and characteristics of propylthiouracil (PTU)-associated small vasculitis (ASV),and to provide reference for rational drug use in the clinic. METHODS:ADR/ADE case reports of PTU-ASV published during 1990-2016 were retrieved. The data of 118 ADR cases were analyzed statistically. RESULTS:The incidence of PTU-ASV was higher in female and was highest in 18-59 age group. Drug dose of 87 patients were within 600 mg/d,and the inci-dence of PTU-ASV was the highest within 1-5 years after medication. Main clinical manifestations were renal and lung function in-jury. After drug withdrawal,59 patients received hormone therapy,and 30 patients received hormone combined immunosuppressive agent. Finally,115 patients were recovered and 3 patients died. CONCLUSIONS:In older to reduce or avoid the occurrence of ADR,it is necessary to regularly check antineutrophil cytoplasmic antibody related indexes and evaluate the symptoms of ADR.

Objective: To investigate the community promotion feasibility of superficial needling plus club swing for post-stroke motion impairment of the shoulder joint. Methods:A total of 180 cases (duration <1.5 years) with post-stroke motion impairment of the shoulder joint were recruited from three community health centers in Changning District, 60 from each community. They were randomly allocated into an observation group (n=90) and a control group (n=90). Patients in both groups received standard internal and rehabilitation care. Patients in the observation group received additional superficial needling plus club swing. The visual analogue scale (VAS) was conducted before and 60 d after the treatment to evaluate the severity of shoulder pain. The active movement of the shoulder joint and activities of daily living (ADL) were also observed. Results:There were no between-group statistical differences before the treatment (allP>0.05). After a 60-day treatment, the shoulder pain severity, active range of motion of the shoulder joint and ADL in the observation group were significantly improved than those in the control group (allP<0.01). In addition, no adverse events were reported by participants in the observation group. Conclusion:Superficial needling plus club swing plays a positive role in improving post-stroke motion impairment of the shoulder joint. This safe, reliable and economical therapy has good patient compliance and is suitable for community promotion.
