AIM: To evaluate the efficacy and safety of vitrectomy combined with internal limiting membrane ( ILM) peeling for treating foveoschisis in high myopia.
METHODS:Thirty high-myopia patients (30 eyes) with foveoschisis from March 2011 to March 2013 were divided two groups: the treatment group ( 16 eyes ) was treated with vitrectomy combined with ILM peeling, and the control group (14 eyes) was treated only with vitrectomy. The foveoschisis reattachment and and best spectacle-correction were measured preoperatively and 2mo after surgery.
RESULTS: The improvement of foveoschisis reattachment and best spectacle - correction in the treatment group was significantly better than those in the control group (P<0. 05).
CONCLUSION: Vitrectomy combined with ILM peeling is a safe and effective treatment for foveoschisis in high myopia.

OBJECTIVETo study clinical results of the manual reduction in treatment.

METHODSFrom October 2010 to April 2013,39 children with Monteggia fracture associated with anterior interosseous nerve injury were treated by manual reduction and fixation on buckling rotation backward,including 17 females and 22 males with an average age of 6.3 years old ranging from 3.2 to 11 years old. Among them, 15 cases were on the right side and 24 cases on the left. The course of disease was 40 minutes to 8 days (averaged 1.5 days). There were 7 cases with skateboard injured, 13 cases with stumble injured, 11 cases with falling injured,8 cases with air bed injured. According to Bado classification, 13 cases were type II, 22 cases were type III, 4 cases were type IV.

RESULTSThe distal forefinger showed exercise normally in 34 cases at 3 weeks after treatment, and the patients restored normal activities at 6 weeks after treatment. All patients were follow-up from 54 days to 6 months (averaged 67 days. According to Mayo elbow functional evaluation standard,the scoring result was 19.62±1.35 in activity, 45.00 ± 0.00 in pain, 9.87 ± 0.80 in stability, 25.00±0.00 in strength, 99.49 ±1.92 in total. The outcome of all patients was excellent and good evaluation results.

CONCLUSIONIf the anterior interosseous nerve injury could be identified early and treated timely, patients could gradually restore reasonable function and recover with satisfactory results. Raising understanding of anterior interosseous nerve injury can effectively reduce misdiagnosis.

Objective To evaluate the situation of blood concentration detection in Zunyi city by the way of analyzing the practice of blood concentration detection for the past 4 years .Methods The bood samples of 194 928 persons who were voluntary blood donators since full implementation of centralized blood test from February 2011 to December 2014 were analysed .Results The unqualified rates of the 5 detection indicators from the seven blood center banks were closed to the centre blood station ,which was rang from 3 .15% to 4 .85% ,the total unqualified rate was 3 .72% and no significant difference was found(P> 0 .05) .Since the concentration of blood detection ,blood donators in the 7 blood center blood banks increased year by year .Conclusion Blood concen-tration detection improves the blood test quality in this single region ,and promotes the development of blood donation career .

Objective To screen for differential expression of genes in bone marrow mesenchymal stem ceils (MSCs) stimulated by electromagnetic fields (EMFs) and to study the mechanism of differentiation of the bone mar- row MSCs induced by EMFs.Methods Mouse bone marrow MSCs were isolated and cultured in vitro.The third- passage cells were stimulated by EMFs,then the total RNA was extracted,purified to cDNA and reversely transcribed to yield a cRNA probe.The cRNA probes from stimulated and control cells were labelled with Cy5 and Cy3,respec- tively.The two samples were hybridized with a mouse oligo microarray,and the hybridization signals were scanned. The reverse transcriptase polymerase chain reaction (RT-PCR) was used to identify the interesting genes:Duspl and Rabl.Results A total of 153 differentially expressed genes were found comparing the stimulated group and the control group.There were 74 up-regulated genes and 79 down-regulated genes in the stimulated group.Semi-quantita- tive RT-PCR confirmed that the Duspl and Rabl mRNA expression levels of the stimulated group were up-regulated. Conclusion The gene expression profiles of the bone marrow MSCs were altered after EMF exposure.The genes are involved in cell proliferation and differentiation,transcription control,metabolism and response to stress.These re- sults provide deeper insight into the mechanism of differentiation of the bone marrow MSCs.

Objective:To study the cognitive function and brain white matter fiber change in major depressive patients prior and post-treatment.Methods:Eleven major depressed patients were given antidepressants for 10 weeks, and their conditions were evaluated using 24-item Hamilton Depression Scale(HAMD).The cognitive function was determined by using Wisconsin Card Sorting Test(WCST),part of Wechsler memory scale and diffusion tensor ima- ging(DTI)was scanned before and after treatment.11 healthy people as control group were involved and given the same tests at the same time.Results:(1)The WCST scores of patients increased significantly after treatment(prior treatment Cc:1.6?1.6,Re:67.9?20.0,Rpe:51.5?24.8;post treatment Ce:4.0?2.1,Re:43.2?18.8,Rpe:22.8?16.0,P=0.001/0.000/0.003).There was no difference in number sequence memory in Wechsler memory scale.No difference was found between patients after treatment and control group in either WCST or number sequence memory.The patients made significant improvement in the total score of HAMD after treatment(16?14/54?13,t=6.60,P

Aim To determine potential biomarkers contributed to occurrence, development and recovery of ethanol-induced liver injury in rat and elucidate hepatoprotective effect of Yin Chen Hao Tang based on metabonomic investigation. Methods A UPLC-Q-TOF/MS based metabonomic method was developed for investigating trajectory change and inter-relationship of urinary metabolome of rats with different treatments. Results Four potential biomarkers were determined which contributed to occurrence, development and recovery of ethanol-induced liver injury in rat, and Yin Chen Hao Tang could significantly recover trajectory change in disorder. Conclusion The developed method was successfully applied to investigate ethanol-induced liver injury in rat, and also hepatoprotective effect of Yin Chen Hao Tang was elucidated.
