    Objective To investigate the effects of midazolam and penehyclidine hydrochloride on memory acquisition, consolidation and retrieval processes of mice in stepthrough test. Methods According to stratified randomized block design,150 Kunming mice were divided into 7 groups: midazolam 1 mg•kg-1(group M, n=30), penehyclidine hydrochloride 0.2 mg•kg-1 (group P, n=30),midazolam 1 mg•kg-1+ penehyclidine hydrochloride 0.2 mg•kg-1 (group M+P, n=30) and control group(group NS,n=30); scopolamine 2 mg•kg-1 (group S, n=10) Sodium nitrite 125 mg•kg-1 (group SN, n=10) and 30%alcohol 0.1 mL•(10 g)-1(group A, n=10) as positive control groups. Stepthrough test was used to evaluate the effects of midazolam and penehyclidine hydrochloride on memory acquisition, consolidation and retrieval processes of mice. The latencies and the numbers of errors during testing section were recorded as the marks of learning and memory. The effects of midazolan and penehyclidine hydrochloride on memory acquisition, drugs administrated before training section to test memory acquisition. Midazolam, penehyclidine hydrochloride or normal saline was injected intraperitoneally 30 min before training section respectively. Positive drug scopolamine was injected intraperitoneally 15 min before training section. The effects of midazolan and penehyclidine hydrochloride on memory consolidation,drugs administrated immediately after training section to test memory consolidation.Midazolam, penehyclidine hydrochloride or normal saline was injected intraperitoneally immediately after training section respectively. Positive drug sodium nitrite was injected subcutaneously. The effects of midazolan and penehyclidine hydrochloride on memory retrieval, drugs administrated before testing section to test memory retrieval. Thirty min before testing section, midazolam was injected intraperitoneally, or positive drug ethanol was gavaged. Fifteen min before testing section, penehyclidine hydrochloride, or normal saline was injected intraperitoneally Results Midazolam impaired memory acquisition and consolidation when single administrated or associated with penehyclidine hydrochloride. Midazolam associated with penehyclidine hydrochloride did not worsen the effect on memory acquisition, but inhibited the effect on memory consolidation significantly. Midazolam alone or associated with penehyclidine did not impair memory retrieval processes. Penehyclidine hydrochloride alone did not impair memory acquisition,consolidation and retrieval processes. Conclusion The effects of midazolam and penehyclidine hydrochloride on learning and memory are advantageous for preventing awareness during surgical procedures.

    Objective To study the effects of allitridin on the transcription and expression of TGF-β1 gene in the mice model with disseminative infection of murine cytomegalovirus (MCMV). Methods Sixty BALB/c mice were inoculated with MCMV Smith strains for establishing the model of disseminative infection, and randomly allocated into two groups: placebotreated group and allitridintreated group with a dose of 25 mg•kg-1•d-1. Another 60 mockinfected mice served as controls and were randomly allocated into allitridintreated controls and mockinfected controls. The mice were sacrificed for extraction of serum and splenocytes at 1 d, 3 d, 7 d, 14 d and 28 d after treatment, respectively. Inactive MCMV antigens were used as the stimulants for spleen cell culture in vitro. TGF-β1 levels in the serum and culture supernatant of splenocytes were measured by doubleantibody sandwich ELISA and TGF-β1 mRNA levels in the splenocytes were detected by RT-PCR assay. Results In placebotreated group, the TGF-β1 level in serum reached the peak at the 3 d, then went down gradually and was significantly higher than that of mockinfected controls at 28 d. The changes in TGF-β1 mRNA and protein expression in the splenocytes showed similar change, with significant increase at 3 d, going to peak at 7 d, returning to the level a bit higher than that of mockinfected group at 28 d. Comparing with placebotreated group, TGF-β1 levels both in serum and splenocytes’ supernatant were reduced after 3 days of treatment in allitridintreated group, showing most significant difference from 3 d to 7 d, meanwhile, TGF-β1 mRNA levels were nearly similar to the those of placebotreated group. Conclusion MCMV induce a higher transcription and expression of TGF-β1 gene in the acute phase of infection. However, allitridin can completely inhibit the transcription of TGF-β1 gene and significantly reduce TGF-β1 expressing levels in the serum and splenocytes’ supernatant induced by MCMV.

    Objective To investigate the effects and possible mechanisms of dauricine (Dau) on early afterdepolarizations induced by dofetilide. Methods Cardiac hypertrophy was induced in rabbits by aortic banding; using conventional microelectrode techniques, the effects of dofetilide at the concentration of 1 μmol•L-1 on action potential duration(APD) and incidence of early afterdepolarizations (EADs) were studied and compared in rabbit papillary muscles between control and different pathological conditions, including hypokalemia and hypertrophy; the effects of Dau in concentrations of 30 μmol•L-1on APD and EADs were observed after EADs were induced by the pathologic conditions mentioned above. Results Compared with control, dofetilide significantly prolonged the APD of rabbit papillary muscle; the same phenomena were also found in hypokalemia and hypertrophy; dofetilide significantly advanced the incidence of EADs in hypokalemia concomitant with hypertrophy; Dau inhibited the prolongation of APD and significantly suppressed the incidence of EADs induced by dofetilide. Conclusion Dau exerts good therapeutic effects on early afterdepolarizations induced by dofetilide and these effects may be associated with inhibition of Dau on several ion channels.

    Objective To explore the association between cisplatinbased chemotherapy and diabetes mellitus in 144 patients with locally advanced head and neck cancer. Methods A retrospective study was carried out through analysis of fasting glucose levels in 144 patients with head and neck cancer. Results Six patients with diabetes mellitus prior to chemotherapy were excluded. A total of 138 patients were analyzed. Nine patients with DM (6.5%)were discovered during the chemotherapy, among whom 7 patients had normal blood glucose and 2 had IFG before chemotherapy. In 7 patients (5.1%)with impaired fasting blood glucose(IFG) before the initiation of chemotherapy, two were exacerbated into diabetes mellitus (DM), but remains still keep on IFG. The fasting glucose levels of 9 DM patients before the initiation chemotherapy was markedly lower, compared with that during the chemotherapy period (5.45±0.59 vs 11.44±4.52,P<0.01). Median cisplatin cumulative dose up until the diabetes occurred was 320 mg&#8226;(m2)-1,and median cycles until the appearance of hyperglycemia were 4 cycle. Conclusion Roution doses of CDDP used against head and neck cancers might be a significant risk factor involving in MD development. It was important that blood sugar levels in patients receiving chemotherapy with a cisplatinbased regimen should be assessed regularly.
