120 g?L-1. The estimated intraoperative blood loss was 1 000-1 500 ml. The patients were randomly divided into 3 groups ( n = 16 each): group Ⅰ lactated Ringer's solution (LR); group Ⅱ LR-6% HES and group Ⅲ colloid (6% HES). Blood was removed from radial artery after induction of anesthesia. The target Hct was 28% . The volume of blood removed = body weight (kg)?7.5 ? (preop Hct -target Hct) / 0.5?(preop Hct + target Hct). The removed whole blood was replaced with lactated Ringer's solution in a three to one ratio in group Ⅰ or with 6% HES in a one to one ratio in group Ⅲ. In group Ⅱ half of the removed whole blood was replaced with LR and the other half with 6% HES. The EVLW, HR, BP, Cardiac index (CI) and dp/dtmax were monitored by PiCCO and recorded before induction of anesthesia (T0), immediately after induction of anesthesia (T1), immediately after and 15 min after ANH (T2,3), immediately before and after reinfusion (T4,5) . Hct, colloid osmotic pressure and blood gases were also measured and recorded. Results The 3 groups were comparable with respect to M/F ratio, age, body weight and the volume of whole blood removed. MAP, HR, SpO2 and CVP were stable during operation in all 3 groups. Hct was significantly decreased after ANH as compared with the baseline at T0 in all 3 groups. The osmotic pressure was significantly decreased after ANH in group Ⅰ and Ⅱ and was significantly higher in group Ⅱ and Ⅲ than in group Ⅰ after ANH. CI and dp/dtmax were significantly decreased after ANH as compared to the baseline at T0 in all 3 groups. There was no significant difference in EVLW, PaO2 and [ HCO3- ] among the 3 groups. Conclusion Moderate ANH with crystalloid or colloid has little effect on EVLW and oxygenation in patients with normal cardio-pulmonary function.

ObjectiveTo evaluate the efficacy and safety of combination therapy of tamsulosin and solifenacin for benign prostatic hyperplasia ( BPH ) with overactive bladder ( OAB ).Methods82 patients with OAB and coexisting BPH were randomly divided into tamsulosin group ( n = 38 ) and combination group ( n = 44). The ages were from 50 to 75 y ( averaged, 56.8 ± 8.6). Inclusion criteria: the mean frequency of micturition ≥8 times per day, the frequency of nocturia ≥2 times per day, voiding volume <200 ml each time; for the overactive bladder symptom score ( OA BSS), the 3 rd score > 2, total score > 3. The tamsulosin group accepted tamsulosin 0.2 mg once daily, the combination group accepted tansulouxin 0.2 mg and solifenacin 0.2 mg once daily. Both groups were maintained the corresponding therapy for 12 weeks.The international prostate symptom score (IPSS), Qmax, residual urine volume, OAB score and adverse reactions were recorded.ResultsThe values of IPSS ( 19.5 ±2.2 vs 15.6 ±2.4, P =0.027), the voiding symptom score ( 15.6 ± 2.4 vs 3.4 ± 1. 7, P = 0. 022) and Qmax ( 13.7 ± 3.8 vs 16.6 ± 4.1, P = 0. 034 )improved significantly after treatment in tamsulosin group ( P < 0. 05 ). The values of IPSS ( 19.7 ± 2.3 vs 9.7 ± 3.0, P <0. 001), the storage symptom score (13.8 ± 1.9 vs 5.6 ± 1.6, P <0. 001 ), OABSS (10.3 ±1.8 vs 5.3 ±1.3, P <0.001) and Qmax(14.1 ±4.1 vs 17.2 ±3.5, P=0.027) also improved significantly after treatment in combination group ( P < 0. 05 ). The values of IPSS ( 9.7 ± 3.0 vs 15.6 ±2.4, P < 0.001 ), the storage symptom score (5.6 ± 1.6 vs 12.0 ± 1.6, P < 0.001 ) and OABSS ( 5.3 ±1.3 vs 9.7 ± 2.7, P < 0. 001 ) improved significantly in combination group than those in tamsulosin group ( P <0.001 ). There were no difference between two groups in values of the voiding symptom score, Qmax and residual urine volume ( P > 0.05 ). The incidences of adverse reactions in tamsulosin group and combination group were 7.9% (3/38) and 20.5% (9/44) without significant difference. There was no acute urinary retention in both groups.ConclusionsIt is effective and safe for patients with BPH and OAB to accept combination therapy of tamsulosin and solifenacin.

OBJECTIVE:To establish a method for full-length cDNA library of Xinjiang Artemisia rupestris. METHODS:Mod-ified Trizol method was adopted to extract total RNA in young leaves of A. rupestris,it was transcribed into single-strand cDNA, and then synthesized into double-strand cDNA by long-distance polymerase chain reaction(LD-PCR)method. PCR product was di-gested by proteinase K and sfiⅠ,and then fractionated by CHROMA SPIN-400 columns. The cDNA longer than 0.4 kb were col-lected and ligated to phage λTriplE × 2,and then protein packaging was performed. Full-length cDNA library was established by SMART technology. 20 monoclonal were randomly selected from the library,and electrophoresis was used to determine the primary library titer,library capacity,recombinant positive rate and length of insert cDNA. RESULTS:The primary library titer was 1.94× 107 pfu/mL,library capacity was 0.97×107 pfu;recombinant positive rate of insert cDNA was 96% and length was 0.5-2.0 kb with an average of 0.9 kb. CONCLUSIONS:The established library is high in capacity and quality,which can provide basis for estab-lishing cDNA library of Xinjiang A. rupestris.
