International Eye Science 2014;(12):2214-2216
AlM:To evaluate the early diagnosis of sub-clinic stage of diabetic retinopathy.
METHODS: This was cross sectional study, multifocal retina electroretinogram ( mf-ERG ) , contrast sensitivity ( CS) and central retinal artery color Doppler examination were recorded from 30 cases ( 30 eyes ) matched control subjects, 35 cases (35 eyes) with type 2 diabetes mellitus (DM) without diabetic retinopathy ( NDR) and 38 cases ( 38 eyes ) with non-prolifera tive diabetic retinopathy ( NPDR) . One-way ANOVA and SNK-q test were used for data analysis.
RESULTS: P1 response density of NDR patients were found decrease, N1 implicit time were delayed. Which were related with the degree of retinopathy (P<0. 05);CS of NDR patients were found significant in middle and high frequency ( P < 0. 05 ), NPDR patients were found significant in full frequency ( P<0. 05 ); Central retinal artery (CRA) blood flow in the control groups and NDR groups were not found statistically significant (P>0. 05), The differences between normal group, NDR group and NPDR group were found statistically significant (P<0. 05).
CONCLUSlON: mf-ERG and CS are sensitive indexes for early evaluation of visual function in patients with diabetes mellitus, with development of the disease, CRA blood flow also appears to decline.

Objective To explore the effect of electromyogram-triggered neuromusclar stimulation (ETNS) on motor function of upper limbs of stroke patients. Methods 45 stroke patients from July, 2011 to December, 2012 in China Rehabilitation Research Center were randomly divided into control group (n=15), neuromuscular electrical stimulation (NMES) group (n=15) and ETNS group (n=15). 3 groups were given routine medication and rehabilitation treatment. They were assessed with the largest surface electromyography (sEMG), Simple Test for Evaluating Hand Function (STEF), and modified Barthel Index before and after treatment. Results After treatment, the range of sEMG of extension carpi radialis and STEF improved in three groups (P<0.05). NMES group and ETNS group were better than the control group (P<0.05), and ETNS group was better than NMES group (P<0.05). The scores of modified Barthel Index rose (P<0.05), NMES group and ETNS group were better than the control group (P<0.05). Conclusion Both NMES and ETNS can improve the motor recovery of upper limbs after stroke, and ETNS is more effective.

OBJECTIVETo investigate the method of medial transposition of the radial nerve in plate fixation of lower segment fracture of humerus.
METHODSFrom January 2010 to December 2013,31 patients with medial transposition of the radial nerve in plate fixation of lower segment fracture of humerus, including 18 males and 13 females ranging in age from 26 to 58 years old with a mean of 37 years old. The time between injury and operation was 1 to 8 days with an average of 4.5 days. According to AO classification, 7 fractures were type A1, 3 fractures were type A2, 6 fractures were type A3, 2 fractures were type B1, 4 fractures were type B2, 2 fractures were type B3, 4 fractures were type C, 3 fractures were type C2. No patients had any signs of radial nerve injury. The results were evaluated with DASH (disability of arm-shoulder-hand) Questionnaire by the American Academy of Orthopedic Surgeons (AAOS) which 0 indicated normal upper extremity function, and 1 to 100 indicated varying degrees of damage to the function of the upper extremties.
RESULTSThere was no neurologic complication or postoperative wound infection in this series. The followed-up period ranged form 8 to 15 months (means 11 months) postoperatively. The clinical outcomes were evaluated with DASH Questionnaire, the score before operation was 76.2±11.8, the final follow-up score was 8.2±7.4, the final follow-up score was significant higher than before operation (P<0.01). The function of the upper extremities recovered satisfactorily.
CONSLUSIONThe method of medial transposition of the radial nerve in plate fixation of lower segment fracture of humerus can avoid iatrogenic radial nerve injury effectively.

OBJECTIVE:To investigate the occurrence of ADR induced by Shuxuening injection in Beijing area,and to pro-vide reference for rational drug use in clinic. METHODS:ADR induced by Shuxuening injection in Beijing area during 2003-2013 was classified statistically in respects of population,organs/systems involved in ADR,clinical manifestations,occurrence time, drug combination and prognosis. RESULTS:Of 1648 ADR cases,the incidence of ADR in the elderly patients was higher than young patients,and that of female patients (60.92%) was higher than that of male patients (39.14%). Multiple organs/systems were involved in Shuxuening injection-induced ADR,and top 3 were nervous system (422 cases,21.33%),skin and its appen-dants (411 cases,20.78%) and others (305 cases,15.42%). Clinical manifestations were skin rash,itching,dizziness and ner-vousness,palpitation,arrhythmia,etc. ADR mostly occurred within 5-30 min after medication. In ADR reports,there were a vari-ety of drugs combined with Shuxuening injection. Shuxuening injection combined with Alprostadil injection was most common(61 cases,accounting for 23.46% of drug combination). Among 1648 ADR cases,there were 622 cured cases and 1039 cases im-proved,4 cases were not improved,3 cases had sequelae and 1 case died. CONCLUSIONS:Clinical application of Shuxuening in-jection should strictly follow the indications of drug package inserts;differentiation of symptoms and signs is based on specific dos-age,solvent,route of administration,etc. It is necessary to strengthen the prescription check,and strengthen the observation after medication especially for the elderly and other special groups so as to reduce and avoid ADR.

BACKGROUND:Single fracture or colapse of the posterolateral tibial plateau fractures is relatively rare in the clinical work. Rational choice of surgical approach and internal fixation for posterolateral plateau fracture is significant to restore the lower limb force line, maintain the joint stability and obtain good biocompatibility.
OBJECTIVE:To compare the stability and biocompatibility of Carlson posterolateral and posterior midline approaches for the treatment of posterolateral tibial plateau fractures with “T” shaped locking plate.
METHODS:From July 2011 to July 2014, 43 patients with posterolateral tibial plateau fractures, who were treated in the Affiliated Hospital of Jining Medical University, were retrospectively analyzed. Al patients were assigned to two groups according to approaches. In the Carlson posterolateral approach group, 22 cases received “T”-shaped plate insertion by Carlson posterolateral approach. In the posterior midline approach group, 21 cases received “T”-shaped plate insertion by posterior midline approach. After repair, perioperative data, fixation effects and knee function score were compared and analyzed between both groups.
RESULTS AND CONCLUSION:(1) 43 cases (43 knees) of posterolateral tibial plateau fractures were folowed up strictly. (2) No significant difference in operation time, fracture healing time, total load time, Hospital for Special Surgery score at 12 months postoperatively, tibial plateau angle and posterior slope angle immediately and 12 months postoperatively was detected between both groups (P > 0.05). (3) Significant differences in fracture exposure, blood loss, and excelent and good rate of Rasmussen at 12 months postoperatively were identified in both groups. Moreover, above indexes were better in the Carlson posterolateral approach group than in the posterior midline approach group (P< 0.05). (4) These findings confirmed that for a single fracture or colapse of the posterolateral tibial plateau fractures, two kinds of surgical approaches can achieve ful and direct exposure. Carlson posterolateral approach has good repair effect, fixation effect and biocompatibility.
