Computerized analysis of blood pressure in conscious unrestrained Sprague-Dawlay rats was first used in China for the effects of ketanserin on blood pressure and blood pressure variability. The results showed that ketanserin significantly lowered blood pressure variability. Besides, they revealed for the first time that level of blood pressure variability directly influenced antihypertensive effect of ketanserin. These findings might be of importance in antihypertensive treatment.

Objective:To explore the prevention and management of wound complications of laparoscopic-assisted radical rectectomy in treatment of the lower rectal cancer. Methods:The clinical data of 87 patients with rectal cancer performed laparoscopic radical rectectomy were analyzed retrospectively.Among them,66 cases were performed by total mesenterectomy resection(TME),21 cases by abdominal perineal resection(APR). Results:The rates of wound complications were as follows: the incidence of intestinal lesion was 4.60%;presacral venous plexus lesion 3.45%;vagina lesion 3.45%;prostate lesion 2.30%;seminal vesicle and deferent duct lesion 2.30%,and ureter lesion 1.15%. Except for one case with changing operative operation,all wound of organs were treated in Laparoscopic techniques.The mean hospitalization was 11d(9~14d).There was no postoperative complication during the follow-up in 14 months. Conclusions:Laparoscopic radical rectectomy is applicable to rectal cancer at proper indication. In order to decrease the wound complications,advanced laparoscopic skills and affluent experiences with operative recectomy,and being familiar with principles and anatomy of TME,and also changing operative methods in time are required.

Objective To study the effect of new dressing combined with ostomy appliances for treating intestinal fistula .Meth-ods 50 patients with intestinal fistula from September 2009 to September 2012 were taken as the experimental group and treated by the new dressing combined with ostomy appliances .Contemporaneous 29 cases of intestinal fistula as the control group were treated by traditional drainage method .The peristomal skin healthy state in the two groups′patients was evaluated by DET scoring before intervention ,on 5 ,10 ,15 d after intervention .The following indexes on 15 d after intervention were compared between the two groups ,including the infection rate of wound ,times of change dressings and costs of change dressings .Results The DET scores at each follow -up timepoint in the experimental group were significantly lower than those before intervention and those in the control group ,the difference had statistical significance (P<0 .05) .Compared with the control group ,,infection rate of wound were lower ,times of change dressings were fewer ,costs of change dressings was less in experimental group significantly (P<0 .05) at 15 days after treatment .Conclusion New dressing combined with ostomy appliances for treating intestinal fistula could get bet-ter clinical effect .

Objective To explore the variation about the application of fast-track surgery and laparoscopy in treatment for colorectal cancer in recent years.To investigate the probability of combining protocols of the two for treatment for colorectal cancer.Methods The clinical and basic literatures of related researches about colorectal treatment of laparoscopy and fast-track surgery were collected and reviewed.Results Compared with the traditional treatment modalities,both of fast-track surgery and laparoscopy used for the treatment of colorectal cancer have better clinical effects.Conclusions Fast-track surgery and laparoscopic techniques used for the treatment of colorectal cancer are feasible,but the combination of the two should be confirmed by further randomized controlled trials.

Objective To evaluate the osteogenic potential of selected exercises and determine which one has the greatest value for the elderly.Methods Twenty healthy old subjects were recruited in the study.Each subject performed the following four exercises in random order:stepping onto a 4-in riser (STEP),sit-to-stand (STS),jumping (JUMP) and marching (MARCH).The subjects performed successively each of the 4 exercises for 1 minute,with an interval of 3 minutes between each.The Vicon action capture system was used to record the peak ground reaction of the subjects during their exercises.The osteogenic index (OI) was calculated by the formula:OI=peak GRF/ (body weight×9.8) × In (number of loading cycles±1).Results JUMP and MARCH had superior OI value (7.52 ±2.06,6.51 ±1.59) than STEP (5.22 ±0.63) among the4 exercises (P＜0.05).STS was found to have the lowest OI (2.23 ± 0.42) in the elderly.There was no significant correlation between the height and OI in JUMP and MARCH (P ＞0.05).Conclusion STEP and MARCH had the higher OI value and could be deemed as the better ways to induce positive effects on bone health in the elderly population.

The interventional lung volume reduction is developed from the lung volume reduction surgery and endoscopically non-surgical lung volume reduction. It is a X-ray guided transcatheter therapeutic technique, involving intra-bronchial embolization of the target pulmonary lobes with bleomycin(or pure alcohol)-lipiodol emulsion and the proximal target bronchial occlusion with PMMA simultaneously. A stable effect of pulmonary fibrosis and lung volume reduction could thus be obtained with the name of functional pulmonary lobectomy. Although this interventional therapeutic technique is now still on progress of animal experiment but having special potency of clinical application and fruitful furture.

OBJECTIVETo observe the difference in the therapeutic effects on knee osteoarthritis (KOA) among auricular electroacupuncture therapy plus isolated moxibustion with Lingxian herbal paste (combined therapy), electroacupuncture (EA) and TDP irradiation.

METHODSEighty-nine cases were randomized into three groups. In the combined therapy group (30 cases), the auricular electroacupuncture therapy was adopted together with the isolated moxibustion with Lingxian herbal paste. The auricular points were xi (AH4), pizhixia (AT4), shenmen (TF4), etc. The Lingxian herbal paste was applied at Yanglingquan (GB 34), Dubi (ST 35), Zusanli (ST 36), Neixiyan (EX-LE 4), Heding (EX-LE 2) and Ashi points. In EA group (29 cases), EA was applied at the acupoints that were same as those in the isolated moxibustion with Lingxian herbal paste. In TDP group (30 cases), TDP irradiation was given at the affected knee. The treatment was given once every day, 10 treatments made one session and there was 1 week at the interval among sessions. Totally, 3 sessions of treatment were required. KOA clinical symptom and physical sign score and the single item pain symptom score of Lequesne index were observed before treatment and 1 week after treatment in the patients of each group separately. The efficacies were compared among the three groups.

RESULTSOne week after treatment, the total score of symptoms and physical signs of the patients in each group was reduced significantly as compared with that before treatment (all P < 0.05). The improvements in the symptoms and physical signs in the combined therapy group were better than those in the other two groups (1.50 +/- 1.57 vs 2.52 +/- 1.82, 2.63 +/- 1.97, both P < 0.05). The improvement in pain in the combined therapy group was also better than that in the other two groups (2.37 +/- 0.81 vs 2.83 +/- 0.92, P < 0.05; 2.37 +/- 0.81 vs 3.03 +/- 0.77, P < 0.01). The curative rate in the combined therapy group was 40.0% (12/30), which was higher than 17.2% (5/29) in EA group and 20.0% (6/30) in TDP group separately (both P < 0.01). The overall efficacy in the combined therapy group was superior to the other two groups (P < 0.05).

CONCLUSIONThe auricular electroacupuncture therapy plus isolated moxibustion with Lingxian herbal paste is advantageous at the total score of the symptoms and physical signs and the overall efficacy in the patients of KOA as compared with EA at the local acupoints and local TDP irradiation.
