Objective To evaluate the effect of continuous adenosine infusion on mesentery microcirculation during cardiopulmonary resuscitation in rats with asphyxia. Methods Rat model of asphyxia was established in 22 healthy Wistar rats. The animals were then randomly divided into normal saline group (group A, n=10), epinephrine group (group B, n=6) and epinephrine plus adenosine group (group C, n=6). After a 3-min asphyxia without intervention, cardiopulmonary resuscitation (CPR) was started. The cardiac compression was carried out with an electric cardio-pulmonary resuscitation machine (200 times/min). Respiration was restored and maintained with a ventilator with tidal volume of 4ml, breathing rate 50times/min and FiO2 100%. After a 4-min CPR, rats in group A and group B were given normal saline and epinephrine (bolus of 90?g/kg) respectively, and in group C epinephrine (bolus of 90?g/kg) plus 70?g/kg adenosine were given. Electric defibrillation would be initiated if there was ventricular fibrillation. The reperfusion rate of mesentery arterioles and venules, diameter of blood vessels and relative blood velocity were observed. Results The reperfusion rate of mesentery arterioles and venules was significantly higher in group C than in group B (P

Objectives:To study the enzymatic changes and protective effects of ciliary neurotrophic factor (CNTF) on neurons in spinal cord injury (SCI).Methods:SD rats were subjected to incomplete SCI with modified Allen methods.Activities of acetylcholinesterase (AChE) and acid phosphatase (ACP) in spinal cord were quantitatively measured preoperatively,and 3,7,14 days after SCI.Results:AChE activity decreased gradually after injury.ACP activity increased 3 days after injury,and reached peak on the 7th day,then recovered gradually.The rats treated with CNTF showed relatively smooth change of the 2 kinds of enzymes.Conclusions:CNTF plays a role in protecting the spinal cord neurons against injury.

ObjectiveTo observe the effects of comprehensive therapy on central pain after incomplete spinal cord injury. Methods12 patients with central pain after incomplete spinal cord injury who accepted comprehensive therapy were assessed with McGill pain questionnaire (MPQ) and visual analogue scale (VAS) before and after treating. ResultsThe scores of pain rating index sensory quality (PRI-S), pain rating index totality (PRI-T), the number of words chosen (NWC), pain rating index affective quality (PRI-A) and present pain intensity (PPI)max in MPQ and VAS were significantly decreased(P<0.01 or P<0.05).ConclusionThe comprehensive therapy is practical effective on central pain after incomplete spinal cord injury.

In order to evaluate the characteristics of the spray drying of total flavonoids of Epimedium extracts assisted with soybean polysaccharide, a certain percentage of soybean polysaccharide or polyvidone were added to the total flavonoids of Epimedium extract to conduct the spray drying. The effect of soybean polysaccharides against the wall sticking effect of the spray drying was detected, as well as the powder property of total flavonoids of Epimedium spray drying powder and the dissolution in vitro behavior of the effective component. Compared with the total flavonoids of Epimedium spray drying powder, soybean polysaccharide revealed a significant anti-wall sticking effect. The spray drying power which had no notable change in the grain size made a increase in the fluidity, improvement in the moisture absorption and remarkable rise in the dissolution in vitro behavior. It was worth further studying the application of soybean polysaccharide in spray drying power of traditional Chinese medicine.

Objective: To observe the therapeutic efficacy of music electric stimulation of points in treating anxiety. Methods: By adopting a design of multi-centered randomized controlled trial (RCT), a total of 270 patients with anxiety were randomized into a treatment group and a medication group. The treatment group was intervened by music electric stimulation of points, while the medication group was intervened by oral administration of doxepin. The two groups were evaluated by using Hamilton anxiety rating scale (HAMA) and Chinese revised edition of self-rating anxiety scale (SAS-CR) before and after the intervention. The therapeutic efficacies were also compared. Results: The total effective rate was 93.6% in the treatment group versus 92.3% in the medication group, and the between-group difference was statistically insignificant (P>0.05). After the treatment, the aggregate scores of HAMA and SAS-CR were significantly changed in both groups (both P<0.001), and the inter-group differences were statistically insignificant (P>0.05). Conclusion: Music electric stimulation of points can produce equivalent efficacy in treating anxiety compared to doxepin. Thus, it can be taken as a choice in the treatment of anxiety.

OBJECTIVETo study therapeutic effects between hook plate fixation and modified Weaver-Dunn surgery for the treatment of acromioclavicular joint dislocation.

METHODSForty patients with fresh acromioclavicular joint dislocations of type III according to Rockwood classification were reviewed. All the patients were divided into two groups: hook plate fixation group and modified surgery group. There were 20 patients in hook plate fixation group, including 13 males and 7 females, with an average age of (37.45 +/- 14.29) years old; 12 patients had injuries in the left and 8 patients had injuries in the right; preoperative Constant-Murley score was 40.75 +/- 10.40. And there were 20 patients in modified surgery group,including 11 males and 9 females, with an average age of (41.65 +/- 14.83) years old; 11 patients had injuries in the left and 9 patients had injuries in the right; preoperative Constant-Murley score was 42.75 +/- 8.18. The Lazzcano standard, Constant-Murley score and imaging changes were used to evaluate shoulder joint function before and after surgery.

RESULTSAll the patients were followed up,and the duration ranged from 7 to 32 months,with an average of 24 months. According to Lazzcano evaluation, 16 patients got an excellent result,3 good and 1 poor in modified surgery group with no re-dislocation, and 1 patient had pain more than middle degree; while in hook plate fixation group, 9 patients got an excellent result, 7 good and 4 poor, 1 patient had re-dislocation, and 3 patients got pain more than middle degree. The therapeutic effects of modified surgery group were better than those of hook plate fixation group. Constant-Murley scores:preoperative 42.75 +/- 8.18 vs 93.40 +/- 4.04 at the latest follow-up in modified surgery group; preoperative 40.75 +/- 10.40 vs postoperative 88.40 +/- 4.81 and 92.05 +/- 4.49 at the latest follow-up in hook plate fixation group. The postoperative scores all improved compared to preoperative scores in two groups. And there was no statistical difference of scores at the latest follow-up between two groups.

CONCLUSIONThe surgery of allograft tendon transplantation combined with anchor fixation to strengthen coracoclavicular ligament, as well as part transposition of acromiocoracoid ligament and resection at the distal part of clavicle may got safety fixation and less postoperative complications compared with hook plate internal fixation.

Oleanolic acid-precipitated calcium carbonate solid dispersion was prepared by using solvent evaporation method. The microscopic structure and physicochemical properties of solid dispersion were analyzed using differential scanning calorimetry and scanning electron microscopy (SEM). And its in vitro release also was investigated. The properties of the precipitated calcium carbonate was studied which was as a carrier of oleanolic acid solid dispersion. Differential scanning calorimetry analysis suggested that oleanolic acid may be present in solid dispersion as amorphous substance. The in vitro release determination results of oleanolic acid-precipitated calcium carbonate (1: 5) solid dispersion showed accumulated dissolution rate of.oleanolic acid was up to 90% at 45 min. Accelerating experiment showed that content and in vitro dissolution of oleanolic acid solid dispersion did not change after storing over 6 months. The results indicated that in vitro dissolution of oleanolic acid was improved greatly by the solid dispersion with precipitated calcium carbonate as a carrier. The solid dispersion is a stabilizing system which has actual applied value.

In order to evaluate the characteristic of porous starch (PS) as the solid dispersions carrier of the total Epimedium flavonoids (TEF), the PS was used. The dissolution of icariin was selected as an indicator to analyze the differences of dissolution between TEF and its solid dispersion. TEF was characterized by scanning electron microscopy (SEM), differential scanning calorimetry (DSC) and X-ray powder diffraction (XRD). Solid dispersion was irregular block and no powder characteristics of TEF and PS could be seen in SEM, DSC and XRD analysis suggested that TEF may be present in solid dispersion as amorphous substance. The dissolution rate of icariin has been improved significantly when the proportion of TEF and PS was 1:2. PS as a traditional solid dispersion carrier is worthy of further study.
