Objective To explore the clinic value and efficacy of color Doppler ultrasound guided percutaneous microwave/radiorequency thermoablation for secondary hyperparathyroidism. Methods Fifty-six cases of secondary hyperparathyroidism who came from nephrology department of Beijing Friendship Hospital in the period of September 2012 to September 2013 were treated by color Doppler ultrasound guided percutaneous microwave/radiorequency thermoablation. One hundred and thirty-eight glands underwent this treatment and were evaluated by contrast enhanced ultrasound before, during and after operation. The levels of serum parathyroid hormone (PTH) were measured before and at 1 week, 1 month, 6 months and 1 year after treatment. Results The whole 56 cases achieved 1 month follow-up and 34 cases and 12 cases achieved 6 months and 1 year follow-up, respectively. Two special cases had been excluded. The PTH levels of 54 cases were signiifcantly different between after and before treatment [(369.5±183.4) ng/L vs (1321.6±471.4) ng/L, t=10.727, P=0.000]. The PTH levels continued to fall at the ifrst week after treatment, but there was no statistical signiifcance between the ifrst week and the ifrst day after treatment [(324.6±172.8) ng/L vs (369.5±183.4) ng/L], while there was signiifcantly different between the ifrst week after treatment and before treatment [(324.6±172.8) ng/L vs (1321.6±471.4) ng/L, t=9.364, P=0.000]. The PTH levels increased from (324.6±172.8) ng/L to (332.5±164.9) ng/L at 1 week and 1 month after ablation, while there was no signiifcant difference.But there is signiifcantly different between 1 month after treatment and before treatment (t=11.348, P=0.000). The PTH level at 6 months after treatment [(205.2±136.3) ng/L] and 1 year after treatment [(177.1±171.5) ng/L] had signiifcant difference compared with the value before treatment (t=8.737, P=0.000; t=7.655, P=0.017). Conclusion Color Doppler ultrasound guided percutaneous microwave/radiorequency thermoablation can be considered as a feasible and effective nonsurgical alternative treatment for secondary hyperparathyroidism patients.

Objective To observe the therapeutically effect of kangnao liquid on Pi3k mRNA and Aktm RNA ex-pressions in rats with focal cerebral ischemia-reperfusion (I/R) injury. Methods 180 male SD rats were randomly divided into 6 groups:sham operated group, model group, three kangnao liquid groups (high-dose, medium-dose and low-dose) and nimodipine group. Rats in kangnao liquid groups were administrated with kangnao liquid of 24 g/(kg · d), 12 g/(kg · d) and 6 g/(kg · d), orally once a day. Rats in nimodipine group were given nimodipine 1 mg/(kg · d). Rats in model group and sham group were treated with the same volume of distilled water for 7 days. The animal model of middle cerebral artery occlusion (MCAO) was established by a monofilament method from right internal carotid artery. The neurological evaluation was per-formed 24 h after reperfusion. The in situ hybridization was used to investigate the expression levels of Pi3k mRNA and Akt mRNA in rats on 12 h, 24 h, 48 h, 72 h and 168 h after ischemia for 2 h. Results Compared with model group, neurological functions were improved significantly in kangnao liquid groups. The expression levels of Pi3k mRNA and Akt mRNA were al-so significantly higher in kangnao liquid groups than those of model group. The expression levels of Pi3k mRNA and Akt mRNA were significantly higher in nimodipine group than those of model group, but which were lower compared with those of high-dose and medium-dose kangnao liquid groups. Conclusion Kangnao liquid can protect nerve cells by enhancing the expressions of Pi3k mRNA and Akt mRNA in rats with cerebral ischemia-reprefusion injury.

Objective To investigate the effect of ultrasound-guided subcostal transverses abdominis plane (TAP) block with dexmedetomidine after laparoscopic radical operation. Methods 40 patients underwent laparoscopic radical operation for colorectal cancer were randomized into dexmedetomidine group (group DEX) and control group (group CON). All the patients received ultrasound-guided subcostal TAP block after operation, Group DEX with dexmedetomidine 1 μg/kg and 0.25% ropivacaine to 20 ml, and group CON with 0.25% ropivacaine 20 ml. All the patients were assessed with Ramsay scores and the pain at rest and on coughing were assessed with Visual Analogue Scale (VAS), 2, 6, 12, 24 and 24 hours after operation. The highest level and the duration of sensory blockade, the first time and the total times of pressing the analgesia pump in the first day after operation, and the requirements of sufentanil were recorded. First flatus time, first diet time and the length of hospital stay were compared. Results The scores of VAS were significantly less (P<0.001), and the Ramsay scores were more in the group DEX than in the group CON (P<0.01) 2, 6 and 12 hours after operation; with the longer time of sensory blockade (P<0.001), the later to first press the analgesia pump (P<0.001), the less frequence of pressing the analgesia pump (P<0.001), and less dosage of sufentanil (P<0.001). The first flatus time, first diet time were significantly earlier in the group DEX than in the group CON (P<0.001), with the less length of total hospital stay (P<0.001). Conclusion Dexmedetomidine can promote the anaesthesia of ultrasound-guided subcostal TAP block with ropivacaine and improve the recovery after laparoscopic radical operation.

Cocrystal separation technology is a technology that utilizes coformers to selectively form cocrystals with target compounds and separate them from mixed systems. Our study used puerarin (PUE), daidzein (DDZ), and genistein (GEN) as model drugs, which have similar structures and are the main isoflavones in Pueraria lobata root. The separation and purification processes in the modern traditional Chinese medicine (TCM) of these three components use conventional column chromatography, recrystallization, and other technologies, which have the issues of lengthy separation cycles, high solvent consumption, and inefficient preparation. Different with existing separation technology, our team used the early-found cocrystal separation method to design a step-by-step extraction and separation experiment of GEN-PUE-DDZ ternary mixture. Caffeine and L-proline were added to the mixed system in turn, GEN-caffeine cocrystal and PUE-proline cocrystal were prepared by suspension method. The cocrystals precipitated out of the solution. The purities of the GEN-caffeine cocrystal and the PUE-proline cocrystal could achieve 93% (the purity of GEN) and 99% (the purity of PUE). Besides, the purity of DDZ could also be increased by 6.76 times. This study proposed a simple operating, low cost and wide application range separation method different from the traditional separation method and realized the separation of structurally similar chemical components in TCM, laying a foundation for the application of cocrystal technology in the separation and refining of TCM.

To explore the optimized dispatch of the rescue resources based on the mastered resources informa-tion. The objective function was set as the shortest rescue time, and 0-1 programming models were established and solved for the conditions that the number of medical rescue units was more or less than needed by the missions. In the two conditions, the model's calculated results were both optimal, and could be used to obtain the optimal dispatch solutions while the medical rescue time was the shortest. The 0-1 programming model can be effectively used to optimize dispatch strategy for medical rescue team.
