OBJECTIVE:To observe the occurrence of paclitaxel(PTX)-induced muscle soreness and therapeutic efficacy and safety of diclofenac sodium. METHODS:Among 84 patients with malignant tumor receiving PTX chemotherapy,56 patients suf-fered from PTX-induced muscle soreness,among which 22 female patients suffered from medium and severe muscle soreness and then were randomly divided into group A and B,with 11 cases in each group. Group A was given Diclofenac sodium sustained-re-lease tablet 75 mg orally,once a day;group B was given Paracetamol and tramadol hydrochloride tablets one tablet orally,once a day,and then given Promethazine hydrochloride injection 100 mg subcutaneously,2-3 times a day when muscle soreness could not be born. Treatment course of both groups lasted for 5 d. The distribution of muscle soreness were observed. The onset time and dura-tion of muscle soreness were also observed as well as pain relief and the occurrence of ADR in group A and B. RESULTS:Among 84 cases,the incidence of muscle soreness was 66.67%,among which mild pain accounted for 23.81%,moderate pain accounted for 13.10%,and severe pain accounted for 29.76%. Among 56 patients with muscle soreness,earliest muscle soreness occurred on the day of medication,and most of muscle soreness occurred on 1-3 days after medication,mainly manifesting as sore,activity limitation when severe,associated with fatigue. The pain relief rate of group A and B were 100%,but the incidence of adverse re-actions in group A was significantly lower than group B,with statistical significances(P<0.05).CONCLUSIONS:Diclofenac sodi-um is similar to paracetamol and tramadol hydrochloride in the treatment of PTX-induced muscle soreness,but it is better than paracetamol and tramadol hydrochloride in safety.

Objective To investigate the expression of NMDAR1 in the hippocampus and cerebral cortex of old rats after 30-min -inhalation of 2% isoflurane, and to investigate the effects of isoflurane on the learning and memory functions of old rats and the underlying mechanism. Methods The healthy old male Sprague Dawley rats (n = 36) were randomly divided into the control group, the oxygen group, the 2-hour post-recovery group, the 1-day post-recovery group, the 3-day post-recovery group, and the 7-day post-recovery group. The morris water maze was used to detect the ethological effect of 30-min inhalation of isoflurane , and the immunohistochemistry assay was used to detect the expression of NMDAR1 in the hippocampus (CA1, CA3) and the cerebral cortex. Results The 30-min inhalation of 2% isoflurane inhibited the learning and memory abilities of old rats at 2 h post-recovery. On 1 d post-recovery, the inhibition of learning and memory began to reduce, then on 3 d and 7 d post-recovery, the learning and memory abilities continously recovered. The expression of NMDAR1 in the rat hippocampus and cerebral cortex decreased at 2 h post-recovery, and reversed on 1 d post-recovery and reached the normal level on 3 d and 7 d post-recovery. Conclusion 30-min inhalation of 2%isoflurane had an inhibitory effect on the learning and memory abilities of old rats, and the attenuation of NMDAR1 in the hippocampus and cerebral cortex may involve in this process.

Objective To subclone express and identify the immune mapped protein 1 IMP1 which encodes a surface an?tigen of Toxoplasma gondii. Methods The cDNA of T. gondii RH strain was synthesized by reverse transcription PCR the IMP1 open reading frame ORF was amplified by PCR using the T. gondii RH strain cDNA as template the PCR products were identified by TA?cloning and sequencing then the IMP1 ORF was subcloned into the NdeⅠand Xho I sites of the vector pET28b and the positive recombinant pET28b?IMP1 was identified by double?digesting and sequencing. The protein of 6 × His tagged IMP1 was inducibly expressed in E. coli strain BL21 DE3 with isopropylβ?D?1?thiogalactopyranoside IPTG and the induction time concentration of IPTG and temperature gradients to optimize protein expression conditions were determined. After the cells carried IMP1 were induced by the optimized conditions and harvested the resulting bacteria were suspended in resuspension buffer and lysed by sonication and the supernatants were loaded onto the Ni2+Chelating Sepharose Fast Flow col?umn for affinity chromatography of the N?terminal 6 × His tagged IMP1 protein. Finally the fusion IMP1 proteins were identified by Western blotting. Results The ORF sequence of IMP1 was successfully subcloned from the cDNA of Toxoplasma Gondii RH strain and the amplified product was sequenced and identified based on which the IMP1 ORF gene was inserted into the prokaryotic expression vector pET28b and the recombinant pET28b?IMP1 was constructed successfully. The double?digesting and sequencing results indicated the validity of the recombinant vector. And the optimized conditions for the expression of IMP 1 was determined namely 0.3 mmol/L IPTG induction for 9 h at 20℃. Furthermore IMP1 protein was expressed solubly and che?lated on Ni2+sepharose beads with high affinity thus this protein could be purified efficiently by affinity chromatography. The pure fusion protein was confirmed with fine immunocompetence by SDS?PAGE and Western blotting. Conclusions IMP1 pro? tein can be high efficiently expressed by the E. coli prokaryotic expression systems the protein of IMP1 is soluble and has stable characters. The study may lay a useful foundation for the following works including in vivo expression of IMP1 crystal structure study of IMP1 and anti?toxoplasmosis subunit vaccine development.
