The study is aimed to provide the theoretical basis for exploiting and utilization of salt-alkaline soil and cultivating Belamcanda chinensis. In this study, we exerted exogenous substances SNP, Spd to relieve the damage of the mixing salt-alkaline stress on B. chinensis seedling which is NaCl, Na2SO4, NaHCO3 and Na2CO3 four kinds of salt molar ratio of 9: 1: 9: 1, salt concentration of 100 mmol x L(-1). The result illustrated that high pH stress is a major factor caused the salt-alkaline stress, the interaction between time and the concentration of each, treatment was observed, what is more, there are synergies between the salt and alkali stress. The content of B. chinensis seedling leaves' membrane peroxidation index (MDA, O2-*) and metabolites (soluble protein, soluble sugars, organic acids) are showing an upward trend in varying degrees under 100 mmol x L(-1) salt-alkaline stress. It is effective to reduce the content of MDA and O2-*. and improve the levels of metabolites, in which the SNP (0.05 mmol x L(-1)) and Spd (0.5 mmol x L(-1)) to alleviate damage effects is the best. Therefore we can hold the conclusion that SNP and Spd can effectively mitigate the damage of B. chinensis seedling on salt-alkaline stress, improve the resistance ability of B. chinensis seedling which can provide the scientific basis for the utilization of salt-alkaline soil, and the cultivation of B. chinensis.

Medication has become the first-line option for the management of lower urinary tract symptoms induced by benign prostatic hyperplasia (LUTS/BPH) for its advantages in controlling the symptoms, inhibiting BPH progression, and reducing serious complications and surgical risks. Recent years have witnessed remarkable achievement in the studies of phosphodiesterase type 5 inhibitors (PDE5-Is) in the treatment of LUTS/BPH. PDE5-Is can effectively alleviate LUTS/BPH, with even better efficacy when combined with al-ARAs.

The effectiveness of vitamin C in treating Cr(VI)-contaminated water is being evaluated. Cr(VI) is an identified pollutant of some soils and groundwater. Vitamin C, an important biological reductant in humans and animals, can be used to transform Cr(VI) to essentially nontoxic Cr(III). The removal efficiency was 89% when the mass concentration of vitamin C was 80 mg/L in 60 min, and nearly 100% Cr(VI) was removed when the mass concentration was 100 mg/L. Our data demonstrated that the removal efficiency was affected by vitamin C concentration, the reaction temperature and the dissolved oxygen concentration. The reaction mechanism of Cr(VI) by vitamin C was presented. Our study opens the way to use vitamin C to remediate Cr(VI)-contaminated soils and groundwater.

Catalytic wet air oxidation (CWAO) of o-chlorophenol in wastewater was studied in a stainless steel autoclave using four different Fe catalysts in the temperature range of 100-200 degrees C. Experimental results showed that high rate of o-chlorophenol and COD(Cr) (Chemical Oxygen Demand, mg/L) removal by CWAO was obtained at relatively low temperature and pressure. The catalysts Fe2(SO4)3, FeSO4, Fe2O3 and FeCl3 all exhibited high catalytic activity. More than 93.7% of the initial COD(Cr) and nearly 100% of o-chlorophenol were removed at 150 degrees C after 150 min with FeSO4 as catalyst. The CWAO of o-chlorophenol was found to be pseudo-first order reaction with respect to o-chlorophenol, with activation energy of 75.56 kJ/mol in the temperature range of 100-175 degrees C.

OBJECTIVETo evaluate operative effects of a new method to reconstruct anterior crucial ligament (ACL) and posterior crucial ligament (PCL) simultaneously by using patellar tendon under arthroscopy.

METHODSFrom November 1999 to November 2003, the injured ACL and PCL of 11 patients were fixated with compressed screws and reconstructed under arthroscopy with the bone-patellar tendon-bone treated with deep hypothermia andgamma radiation. At the same time, 2 patients were treated with medial collateral ligament (MCL) reconstruction, 3 with lateral collateral ligament (LCL) reconstruction, 1 with meniscus suture and 4 with whole or partial resection.

RESULTSAll patients were followed up for 12-26 months (average 16.5 months). The Lysholm score method was employed to evaluate the knee function. The average preoperative score was 45.3 and the postoperative score was 86.4. Anterior drawer test (ADT) was positive in 11 knees preoperatively and feeble positive in one knee postoperatively. Lachman test was positive in 11 knees preoperatively and in one postoperatively, and feebly positive in two postoperatively. Posterior drawer test was positive in 11 knees preoperatively and feebly positive in 2 postoperatively. There were 2 knees with tolerable pain and 2 with knee flexion of 5-20.

CONCLUSIONSAs for simultaneous reconstruction of ACL and PCL under arthroscopy, allogeneic bone-patellar tendon-bone can not only avoid injury and complication caused by autografting, but also help rehabilitation of the knee function.
