The paper is aimed to study the difference in yield and quality at different harvest time and determine the optimum harvest of planting Gentiana in Ludian traditional harvest period. The authors analyzed the variation in fresh weight, dry weight, dry discount rate, length, diameter, volume and the content of gentiopicroside, loganin acid, alcohol-soluble extract and total ash and made a comprehensive appraisal of yield, appearance quality and intrinsic quality by gray relational distance ideal Comprehensive Evaluation method. The results showed that there is a big difference in yield and quality both 2-year-old and 3-year-old Gentiana harvested in traditional harvest period and the comprehensive evaluation more better when harvested more later. It can be seen, Gentiana harvested the later had a better yield and quality in Ludian traditional harvest period. The harvest of Gentiana can be appropriate delayed depending on the particular circumstances of production.

Objective To investigate the significantly elevated incidence of hepatitis C and mortality of cirrhosis and hepatocellular carcinoma (HCC) in Jianping county, and to explore the epidemiological features. Methods The data from database of death registry and infectious disease surveillance in Jianping county, Liaoning Province were analyzed. The distributions of incidence of hepatitis B and hepatitis C, mortality of cirrhosis and HCC in 23 villages and towns were investigated.Spearman's correlation was used to explore the correlations between hepatitis, cirrhosis and HCC.Results The standardized mortality of HCC in males and females in Jianping county were 77. 6/10~5and 22. 0/10~5, respectively, which were 2. 0 and 1. 7 times, respectively of the average levels of Liaoning rural areas. The incidence of hepatitis C was 58. 0/10~5 , which was 9. 5 times of the averagelevel of Liaoning Province. There were positive correlations between incidence of hepatitis C and mortality of cirrhosis (r=0. 495, P = 0. 008), and mortality of cirrhosis and HCC (r=0. 646, P<0.01). Conclusions The incidence of hepatitis C and mortality of cirrhosis and HCC in Jianping county are significantly higher than the average levels of Liaoning Province. Further investigations of the suspected causes are needed.

Background The integration of segregated pathways from the two eyes first appears in V1 neurons,where it not only plays a critical role in the generation of a three-dimensional visual representation.Abnormal visual experiences in critical period usually lead to amblyopia and binocular integration defects.Objective Present study was to investigate how neurons of kitten coordinate their activity patterns in response to synchronous dichoptic stimulus inputs in striate cortex.Methods Spike rate and local field potential(LFP) gamma band(20-90Hz) power of three kitten(1-1.2Kg,8-10 weeks old) to monocular and synchronous dichoptic presented gratings were assessed for 28 binocular neurons in V1 of kitten by in vivo extracellular record method under anaesthesia and paralysis.Ocular dominance index(ODI) and binocular integration index(BII) were assessed and the correlation between these two indexes were analyzed.Results In 28 cells with binocular characteristic,the absolute value of spike-ODI was significant larger than that of LFP-ODI(t=2.606,P=0.021).A positive linear correlation between the ocular preferences of spike and LFP was found(R2=0.513,F=27.423,P=0.003).In dichotic trails,binocular facilitation with BII for spike was 2.348±0.996,showing a significant reduce in comparison with BII for LFP(3.678±1.974)(t=2.671,P=0.019).Binocular integration index for two signals were greater when monocular responses of both eyes were similar(P=0.035 and P=0.124,respectively).Conclusion Both spike rate and gamma band power of LFP exhibited binocular facilitation to synchronous presented dichotic stimuli with significant facilitation induced by balanced monocular responses.Spiking activity and LFP reflect neural activities of different spatial scales and source components.

OBJECTIVETo compare mid-term clinical outcomes between amputation and limb salvage in treating severe open tibial fractures with type Gustilo III B, III C.

METHODSFrom July 2007 to June 2010,68 patients with severe open tibial fractures with type Gustilo III B, III C treated by amputation and limb salvage were retrospectively analyzed. In amputation group, there were 26 males and 12 females with an average age of (44.9±16.3) years old; and 21 cases were type Gustilo (III B, 17 cases were Gustilo III C; amputation were performed in accordance with soft tissue injury degree of shank, fracture types and surgical exploration. In limb salvageg group, there were 21 males and 9 females with an average age of (43.5±14.7) years old; and 23 cases were type Gustilo III B, 7 cases were Gustilo III C; the method of internal fixation and and wound healing were performed in accordance with patients's specific condition. Operative time, blood loss, hospital stay and postoperative infection was compared between two groups; time of loading and rate of return to work was compared; VAS scoring was used to evaluate condition of pain; SF-36 health queationaire was used to assess postoperative life quality.

RESULTSTotally 60 patients were followed up (33 cases in amputation group and 27 cases in limb salvage group) with an average time of 49.1 months. Operative time, blood loss, hospital stay and postoperative infection in amputation and limb salvage group respectively was (109.0±25.7) min, (245.0±58.6) min; (168.0±49.0) ml, (311.0±137.0) ml; (13.8±2.7) d, (28.8±13.1) d; 7.9%, 36.7%. At the final following-up, there was no significance meaning between two groups in VAS scoring and rate of return to work, but time of loading in amputation group was shorter than that of in limb salvage group. Physiological function in amputation group was better than limb salvage group, while body pain was worse; and there was no signicance meaning in psychological health between two groups.

CONCLUSIONAmputation and limb salvage both can treat severe open tibial fractures, and mid-term clinical outcomes between two groups has equivalent efficacy.
