Under the current system, the number of sole foreign -investment hospitals and foreign -domestic joint venture hospitals is growing.They are different from public hospitals in terms of their foperation , market share, medical-service pricing poli-cy and their quality and management of medical care.Mechanisms still need to be developed so that these hospitals could move forward to improve our health-system overall.In the meanwhile, public hospitals should be powered by the patient-centeredphilosophy and improve their management and services to enhance their competiveness.

Aim To investigate whether liver X recep- tors attenuate high glucose-induced apoptosis in H9C2 cells through inhibiting nuclear factor-NF-κB.Methods The lentiviral vector of LXRs was constructed and H9C2 cells cultured in high glucose were infected.The H9C2 cells were divided into 6 groups:control group (5.5 mmol·L -1 glucose),mannitol group(5.5 mmol ·L -1 glucose +27.5 mmol·L -1 mannitol),high glu-cose group(33 mmol·L -1 glucose),green fluorescent protein(GFP)group LXRαgroup,and LXRβgroup. The inhibition rate of H9C2 cells,the mRNA of Bax, Bcl-2,the protein content of NF-κB,Bax,Bcl-2, cleaved caspase-3,and the cell apoptosis were com-pared among these groups.Results LXRs overexpres-sion significantly attenuated high glucose-induced in-crease in Bax NF-κB,cleaved caspase-3 and cell ap-optosis(P <0.05),and increased high glucose-induced decrease in Bcl-2.Conclusion Liver X receptors at-tenuate high glucose-induced apoptosis in H9C2 cells through NF-κB signaling pathway.

Background and purpose: Preemptive analgesia is one of the strategies to treat postoperative pain by preventing the establishment of central sensitization. This study was designed to explore whether the method of flurbiprofen axetil injection combined with bilateral cervical plexus nerve block in thyroid carcinoma surgery as multimodal preemptive analgesia can serve as a better analgesia. Methods: Sixty patients with thyroid carcinoma were randomly divided into three groups. Patients in Group A were treated with flurbiprofen axetil injection combined with bilateral cervical plexus nerve block as multimodal preemptive analgesia. Patients in Group B were anesthetized with bilateral cervical plexus nerve block. General anesthesia alone was used in patients of Group C. The onset time of nerve block, operation time, extubation time and dosage of fentanyl were recorded. The VAS (visual analogue scale) was used to evaluate the pain level, the side effects of drugs were also analyzed. Results: The onset time of nerve block in Group A, Group B were (7.47±1.04) min and (8.75±1.36) min, repectively (P<0.05). The dosage of fentanyl n Group A, B and C were (0.36±0.04) mg, (0.40±0.06) mg and (0.45±0.07) mg, respectively (Group A vs Group B P<0.05; Group A vs Group C, P<0.01).VAS scores of patients in Group C were higher than both Group A and B at 4,8 h after operation. Moreover, patients in Group B got higher VAS scores than that of Group A at 8 h. The side effects of both Group A and B were much less serious than that of Group C. Conclusion: Flurbiprofen axetil injection combined with bilateral cervical plexus nerve block as multimodal preemptive analgesia during thyroid carcinoma surgery can supply better analgesia and opioid-sparing effects, with less side effects.
