AIM:To investigate the clinical signifi cance of C-reactive protein (CRP) values in determining the endpoint of antibiotic treatment for liver abscess after drainage. METHODS: The endpoints of antibiotic treatment in 46 patients with pyogenic liver abscess after complete percutaneous drainage were assessed by performing a retrospective study. After complete percutaneous drainage, normal CRP values were considered as the endpoint in 18 patients (experimental group), and normal body temperature for at least 2 wk were considered as the endpoints in the other 28 patients (control group). RESULTS:The duration of antibiotic treatment after complete percutaneous drainage was 15.83 ± 6.45 d and 24.25 ± 8.18 d for the experimental and the control groups, respectively (P=0.001), being significantly shorter in the experimental group than in the control group. The recurrence rate was 0% for both ***, we could not obtain the follow-up data about 3 patients in the control group. CONCLUSION: CRP values can be considered as an independent factor to determine the duration of the antibiotic treatment for pyogenic liver abscess after complete percutaneous drainage.

The dl-form of the sex pheromone of Japanese b(?)tle and the trail pheromone of Bontebok were synthesised in high purity of (Z)-olefinic configuration. The key step of the syntheses of compounds (1) and (2) involved stereospecific addition of n-alkyl cuprates to acetylene followed by addition of vinyl cuprates to aldehyde (7) and 3-buten--2-one.

This study is aimed to investigate the effect of luteinizing hormone （LH） on maturation and fertilization in vitro of ovine oocytes. The ovine oocytes were cultured in vitro in medium with or without LH, and then checked by confocal laser scanning microscope to observe the distribution of cortical granules stained with FITC-LCA during different maturation periods. Similarly, some in vitro matured oocytes were also fertilized in vitro for analysis of their developmental potentiality further. After being cultured in vitro for 4 h, there were significant differences about the rate of germinal vesicle break down （GVBD） between the treatment （with LH） and the control groups （without any hormones）（36.76% vs 18%, P〈0.05）. Further, there were also significant differences of the cleavage and blastocyst rates between these two groups （67.15% vs 42.37%, 21.9% vs 12.71%, P〈0.05, respectively）. The distribution of cortical granules appeared to spread from the edges to the central site of sheep oocytes following their delaying durations of maturation in vitro. It can be concluded that LH may play a role to delay the occurence of GVBD, prolong the maturation duration of cytoplasm, and enhance the nuclear and cytoplasm synchronization of ovine oocytes matured in vitro and finally improve their in vitro developmental potentiality.

The zonal soils in the south subtropical zone of Fujian are lateritic red soils. A type of dark clayeysoils, which was historically defined as lateritic red soils, derived from weathering products of the basalts wasindicated by the investigation results to be markedly different from lateritic red soils and could be classifiedas Typical Hapluderts. They are distributed as complex zones with the lateritic red soils. The vertisolsin this region were considered as a type of lithogenic soils and the vertic chararteristics delay and inhibitthe soils from allitic processes and then formed an independent soil type. The vertisols have higher fertilityand better agricultural production characters than the lateritic red soils. The different ways in utilizing andmanaging these soils arcording to their properties and fertility are also suggested.

In this context,we firstly synthesized a novel nitrogen-doped multiporous carbon material from renewable biological cells through a facile chemical activation with K;CO;.After sulfur impregnation,the carbon/sulfur composite achieved a sulfur content of about 67 wt%.The C/S composite as the cathode of lithium-sulfur batteries exhibited a discharge capacity of 1410 mAh/g and good capacity retention of912 mAh/g at *** outstanding results were attributed to the synergy effect of microporous carbon and natural doping nitrogen *** believe that the facile approach for the synthesis of nitrogen-doped multiporous carbon from the low-cost and sustainable biological resources will not only be applied in lithium-sulfur batteries,but also in other electrode materials.
