Objective:To analyze the analgesic effectiveness of dezocine after laparoscopic cholecystectomy. Methods: Totally 80 patients with laparoscopic cholecystectomy were randomly divided into the observation group and the control group. The control group was given tramadol 0. 2 mg·kg-1 for anesthetize, the observation group was given dezocine 0. 1 mg·kg-1 analgesia. Conducted according to a simgle drug additional pain status of the patient. After the surgery, the time of surgery, VAS and BCS pain condition score of the pa-tients were analyzed and compared, and the incidence of adverse reactions of the two groups were recorded. Results:After the surgery, the operation time, opening eyes, awaking time and extubation time showed no significant difference in the two groups (P>0. 05). VAS scores of the observation group in 30min, 1h, 2h and 6h after the surgery were significantly lower than those of the control group, and BCS score was significantly higher than that of the control group (P<0. 05). The incidence of adverse reactions in the observation group was significantly lower than that in the control group (χ2 =4. 020 5,P=0. 045 0). Conclusion:The analgesic effect of dezocine after lap-aroscopic cholecystectomy is promising, which can significantly alleviate the pain after the operation and is worthy of wider application.

To date, three techniques of total spondelyctomy were used for spinal tumor, including piecemeal technique, eggshell technique and total en bloc spondelyctomy, and each has specific features and indications. Due to limitations of technique, piecemeal technique and eggshell technique are gradually replaced by total en bloc spondelyctomy in treatment of spinal tumor. Moreover, with technical development, application of total en bloc spondelyctomy in treatment of spinal tumor becomes more rigorous and standard. However, it is controversial about its indications and surgical approach. Postoperative spinal stability reconstruction is achieved through various methods according to different conditions.

Objective To analyse effect of dobutamine on C-reactive protein,D-dimer,BNP and blood gas analysis in children with neonatal pulmonary hypertension.Methods 46 patients who were diagnosed with neonatal pulmonary hypertension in our hospital were collected.All patients were randomly divided into experimental group and control group, 23 cases in each group.Control group was treated with sedation, maintenance of water electrolyte balance, blood pressure, anti-infection,experiment group was treated with dobutamine hydrochloride injection 5μg/(kg· min) intravenous infusion, continuous for 48 h on the basis of conventional therapy, after treatment,the levels of peripheral blood C-reactive protein, D-dimer and BNP and blood gas analysis effect were detected in all patients.Results Compared with control group post-treatment, the serum level CRP,D-dimer, BNP were lower in experimental group ( P <0.05 );the PaO2 and SpO2 levels were higher, the PAH level was lower in experimental group ( P <0.05 ) . Conclusion The dobutamine can significantly reduce the serum CRP, plasma D-dimer and BNP levels in children with neonatal pulmonary hypertension, reduce pulmonary hypertension.

Cimicifugeae is one of the rich sources for various active components and the health promoting and therapeutic values of the components have been corroborated by long-term use in folk medicine and traditional Chinese medicine. Increasing interest in Cimicifugeae pharmaceutical resources has led to the further discoveries of triterpenoid saponins, phenolic compounds, chromones, and many other compounds in various species of Cimicifugeae, and to the investigations on their chemotaxonomy, molecular phylogeny, and bioactivities. Based on our pharmacophylogenetic studies, the progress in phytochemistry, chemotaxonomy, molecular biology, and phylogeny of Cimicifugeae had been summarized since 2007, especially Cimicifuga L. ex Wernisch. and Actaea L., and their relevance to therapeutic efficacy. An exhaustive literature survey is used to characterize the global scientific effort in the phytochemical and biological studies of Cimicifugeae. More triterpenoid saponins have been found in various species, among which the cimigenol type (type A) is predominant. The versatile bioactivities of saponins and extracts, as well as those of phenolics and other ingredients, were summarized and discussed. The morphology-based five-genus classification of Cimicifugeae is not supported by molecular phylogeny. Molecular phylogeny based on nuclear and chloroplast DNA sequences tends to merge Cimicifuga Wernisch., Souliea Franch., and Actaea L. into a single genus. It is indispensable to integrate the emerging technologies into Cimicifugeae research for both the sustainable utilization of Cimicifugeae pharmaceutical resources and finding novel compounds with potential clinical utility and less adverse effects. Systems biology and omics technologies would play an increasingly important role in booming pharmaceutical research involving bioactive compounds of Cimicifugeae. © 2013 Tianjin Press of Chinese Herbal Medicines.
