Objective To study the effect of Zusanli and Guanyuan electroacupuncture ( EA) on inflammatory reaction in patients with sepsis. Methods A prospective and randomized trial was carried out in 58 sepsis patients, and the patients were randomly divided into EA group and control group. Patients in both groups were given conventional western medicine treatment, and EA group received EA at acupoints of Zusanli and Guanyuan additionally. The hospitalization time in intensive care unit ( ICU) of the two groups was compared. The changes of serum lactic acid (LA) level and inflammatory indexes including white blood cell and neutrophil count, C- reactive protein (CRP), erythrocyte sedimentation rate (ESR) and procalcitonin (PCT) of the two groups were observed before and after treatment. Results The hospitalization time in ICU of EA group was less than that of the control group, and the difference was statistically significant ( P<0.05) . On the seventh day after treatment, the serum LA level of EA group was significantly lower than that of the control group ( P<0.05) . Inflammatory indexes of EA group were decreased after treatment compared with those before treatment ( P<0.05) , and on seventh day after treatment, the inflammatory indexes of EA group were significantly lower than those of the control group ( P<0.05) . Conclusion EA at acupoints of Zusanli and Guanyuan is effective for the treatment of sepsis through reducing the inflammatory reaction of sepsis patients.

AlM: To investigate the refractive status of the preschool children in Xiantao, Hubei Province in order to find out the abnormal refraction error beyond the physiological range.
METHODS: ln this cross - sectional study, we investigated preschool children in kindergartens and the scattered ones were 12 716 ( 25 432 eyes ) ranging from 6mo ~ 6 years old. 1 581 children ( 3 162 eyes ) were diagnosed ametropia by Suresight refractive screening instrument, which were confirmed again after mydriasis optometry.
RESULTS: The incidence rate of ametropia in preschool children in Xiantao was 12. 4%, and statistics showed no significant difference between boys and girls (P>0. 05), but had differences of morbility rate among each age group (P<0. 05). With age increasing morbility rate of the refractive error decreased. The simple hyperopia and the compound hyperopia astigmatism were dominant in all refraction error. Professional ophthalmologists diagnosed amblyopia in 261 children (522 eyes), which was 16. 5%, among 1581 abnormal refractive children (3 162 eyes) screened out by Suresight refractive screening instrument.
CONCLUSlON: The incidence rate of ametropia decreases with age increasing in the preschool children from 6mo~6 years old, which imply preschool children should have mydriasis optometry in order to find out amblyopia and other congenital eye disease.

OBJECTIVETo explore the clinical effects of Dynesys system combined with posterior lumbar interbody fusion (PLIF) in treating multiple lumbar degenerative disease.

METHODSThe clinical data of 46 patients with multiple lumbar degenerative diseases treated by Dynesys system combined with PLIF from September 2010 to May 2013 were retrospectively analyzed. There were 17 males and 29 females, aged from 38 to 68 years old with an average of (56.38±11.63) years. Operation section was in L2-L5 of 16 patients (6 with fusion of L4,5 and 10 with fusion of L4,5,L5S1) and in L3-S1 of 30 patients (11 with fusion of L5S1 and 19 with fusion of L4,5,L5S1). Patients were followed up for three times: postoperative 3 months, 1 year and final follow-up. Visual analogue scale (VAS) and Oswestry Disability Index (ODI) were used to assess clinical symptoms preoperatively and postoperatively. All patients underwent flexion/extension radiographs examinations before surgery and at final follow-up. Range of motion (ROM) and disc height index (DHI) were recorded.

RESULTSAll patients were followed up from 16 to 48 months with the mean of (23.23±7.34) months. At third follow-up after operation, ODI and VAS of lumbago and leg pain were significant improved than that of preoperative (P<0.01). DHI of fusion segment was significantly increased than that of preoperative (P<0.05). There was no significant difference in adjacent non-fusion segment between preoperative and postoperative (P>0.05). Postoperative ROM of fusion and non-fusion segments were obviously decreased than that of preoperative. There was no significant difference in ROM of upper adjacent non-fusion segment between 3 months and 1 year after operation (P>0.05), but at final follow-up, the ROM was increased (P<0.05).

CONCLUSIONThe preliminary clinical results of the Dynesys system combined with PLIF in the treatment of multiple lumbar degenerative diseases are satisfactory. It can be determined in fusion or non-fusion according to the individual needs and can reserve the some intervertebral motion, prevent the early degeneration of adjacent segments. However, its long-term clinical efficacy should be verified with long time.

After brief introduction of FISH (fluorescence in situ hybridization),it was discussed of the FISH's application status in research on biological nitrogen removal in recent years. Base on the FISH technology,Characterization of the community in biological reactor could be showed exactly,but more research should be carried out for the study on the effluence on microbial community composition,which was caused by changing operating parameter of biological reactors on the microbial community composition,such as SRT,DO and C/N ratio.The combination of FISH and other methods such as PCR-DGGE and 16S rRNA/rDNA will led to the identification of the microbial community which response for the nitrogen-removal in wastewater treatment plant.

Trypanosoma is a human parasite severely affecting poor tropical areas.However,current frontline drugs for Trypanosoma treatment have severe side-effects with decreased effectiveness.Based on the fact that aminoacyl-tRNA synthetase is a bonafide drug target for several microorganisms,including bacteria and fungi,it is plausible that it may also be effective target of Trypanosoma.The Trypanosoma brucei leucyl-tRNA synthetase(tbLeuRS)was cloned,expressed and purified to develop an in vitro enzymatic assay system.The assay conditions were further optimized for the effective screening of tbLeuRS inhibitors thus establishing an anti-Trypanosoma drug screening system targeting tbLeuRS.The results indicated that this system can be employed for the effective screening of anti-Trypanosoma drugs with satisfactory specificity.In addition,this system can also be used for compound optimization,as well as IC50 testing.Using this system a series of compounds are identified that are effective Trypanosoma inhibitors without toxicity to human cells.Therefore,targeting tbLeuRS may represent a new venue for the development of anti-Trypanosoma drugs.
