In Cantharidin-poisoned rats, nicotinamide-adenine dinucletide dehydrogenase (NADHD) andcytochrome oxidase (CCO) activities of myocardi-um, stomach and intestine were observed in exper-iment histochemically. The result showed thatNADHD and CCO reaction granules were de-creased, stained weakly, and distributed sparselyin myocardium, stomach and intestine of intoxicat-ed rats as compared with the control group. Thus,from the experimental result it was considered thatcantharidin may inhibit the activities of NADHDand CCO in varving degrees.

Based on the histochemical observation ofnicotinamide adenine dinucleotide dehydrogenase(NADHD) and eytochrome oxidase (CCO) activi-ties of myocardium in cantharidine poisoned rats,furthermore, we observed the changes of these en-zymes of the myocardium cytochemically. The re-sult showed that, compared with control group, NADHD and CCO activities were inhibited afteradministration of cantharidin 1 or 2 h, and the in-hibition was found to be more obvious with poison-ing times prolonged, after 24 h, the cristae of mi-tochondria can not be distinguished, and the reac-tion products diffued into stroma to become a ho-mogeneous mass and lost their normal localization.It is indicated that cantharidin might destroy thestructure of mitochondria and interfere the activi-ties of NADHD and CCO of which both are locatedon mitochondria.

Objective To evaluate the effect of optimizing surgerical patients’handover procedures using tracking methodology.Methods Two hundred patients hospitalized between July 2011 and May 2012 were assigned in the control group,in which their handover was conduced conventionally.Another 200 patients between April 2012 to February 2012 were assigned in the observation group,where their handover was done by tracking methodology.The two groups were compared in terms of incidence of adverse events at handover,time for handover and satisfaction of medical staff.Result Compared with the control group,the study group showed significantly lower incidence of adverse events,shorter surgical handover time and higher satisfaction degree of medical staff(P<0.05).Conclusion The tracking methodology can help to optimize handover procedures and quality control management, reduce the incidence of adverse events and improve working efficiency.

Objective To explore the value of 2 dimension and color Doppler flow imaging (2D CDFI) in detection of deep venous thrombosis of the lower limbs. Methods One hundred and one patients, 118 limbs clinically suspected as deep venous thrombosis were examined by CDFI and ascending phlebography. Results The sensitivity of ultrasonogram was 94 4% and accuracy was 98 4%. The highest incidence is 30 4% in the femoral vein. With the ratio 2 2∶1, the incidence of left lower limbs was much higher than the right. Because of different pathological changes in acute, subacute and chronic thrombosis, there are diverse character in 2D CDFI. Conclusions Deep venous thrombosis of the lower limbs can be diagnosed by 2D CDFI, which is a noninvasive, easy and accurate method.

Objective:To observe effects of wrist-ankle acupuncture (WAA) onβ-endorphin (EP), nitric oxide (NO) in uterus tissue and prostaglandin F2α (PGF2α), substance P (SP) in serum of rats with primary dysmenorrhea. Methods:A total of 45 non-pregnant Wistar rats were randomly divided into a control group, a model group and a WAA group, 15 rats in each group. Rats in the model group and the WAA group received continuous abdominal subcutaneous injection of Diethylstilbestrol to establish dysmenorrhea rat models. On the first day after modeling, rats in the WAA group began to receive acupuncture on Point Lower 1 and Point Lower 2, once a day for 10 d. The control group and the model group didn’t receive any treatment. Writhing latencies and frequencies were recorded.β-EP and NO in uterus tissue homogenates and PGF2α, SP in serum were detected. Results:In the model group,β-EP and NO levels were the lowest among the groups, the serum PGF2α level was the highest, and serum SP level was the lowest. These measurements showed significantly difference between the model group and the control group (P<0.05). PGF2α in the WAA group was lower than that in the model group;β-EP, NO and SP levels were higher than those in the model group, with inter-group statistically significant differences (P<0.05). Conclusion: WAA may achieve analgesic effect through decreasing PGF2α, increasingβ-EP, NO and SP to relieve uterine cramps, increase blood flow and promote functional improvement.

Objective To observe the ultrasonic manifestation of metatarsal fatigue fractures and probe into the clinical values of ultrasonic diagnosis and follow-up to the disease.Methods The clinical data and sonographic features of 30 cases with metatarsal fatigue fracture confirmed by X-ray and CT were analyzed retrospectively.Results All the subjects in this study were metatarsals insufficiency fractures located in the second or third diaphysis.2D-ultrasound found microfracture in the cortex and the periosteal elevation by increased vascularity in the early stage.During the 3-month follow-up,thickened cortex and callus shown as the shape of mushroom or cauliflower and a great amount of neovascularisation were visualised with color Doppler flow imaging.Then,the cortex surface became gradually changing from rough to smooth and obvious posterior shadows were observed with the illness progression.Conclusions Ultrasonography could be used to detect the cortical continuity,callus characteristics and blood flow perfusion of fatigue fracture in the different damage stages.

Objective To study the prevention,diagnosis and treatment of the pulmonary embolism after abdominal surgery.Methods The clinical data of patients with acute pulmonary embolism(PE) after abdominal surgery between July 2008 and June 2012 were analyzed retrospectively.The high-risk patients received D-dimer,deep venous ultrasound and pulmonary CT examination to confirm the diagnosis postoperatively.Anticoagulation,thrombolysis,inferior vena cava filter placement were carried out in these patients.The high-risk patients received low molecular weight heparin(LMWH) to prevent PE from January 2010.Results 5 patients with PE survived and 3 patients died.The incidence of venous thromboembolism event was 0.43％ (13/3012) before January 2010 and PE was 0.20％ (6/3012).The incidence of venous thromboembolism event was 0.15％ (7/4803) after taking preventive measures and PE was 0.04％ (2/4803).There was no PE within 1 week since using LMWH after 2010.Lower limb DVT was found in 7 patients including 2 patients with PE after LMWH discontinuance within 2-3 weeks postoperatively.Conclusions Early prevention,diagnosis and treatment of postoperative PE are important for high-risk patients.

Objective To compare anesthetic effect and safety of general anesthesia and combined spinal and epidural anesthesia used in autonomic nervous hyperresponsive surgery for patients with paraplegia.Methods 26 paraplegic patients were randomly divided into two groups-control group and treatment group from February 2011 to November,2015,each with 13 cases.The control group used general anesthesia,while the treatment group used combined spinal and epidural anesthesia,to observe onset time,duration,intraoperative hemodynamic changes and complications,Complications,length of stay and cost,Days and costs of hospitalization,satisfaction of patients and their families,of anesthesia in two groups.Results The dosage of narcotics and the onset time of the treatment group were better than that of the control group.The difference between the two groups was significant,and had statistical significance (P＜0.05) Two groups of patients after surgery,diastolic blood pressure,systolic blood pressure and heart rate were lower in the treatment group than in the control group,and had statistically significant difference (P＜0.05);The postoperative complications of the treatment group were significantly better than those of the control group,and had statistically significant difference (P＜0.05);There were statistically significant differences in postoperative pain degree between the two groups (P＜0.05);Two groups of patients in hospital days,hospital costs,satisfaction rate had statistically significant difference,Have statistical significance (P＜0.05).Conclusion In autonomic nervous hyperresponsive surgery for patients with paraplegia,anesthetic effect and safety of combined spinal and epidural anesthesia is significantly better than that of general anesthesia,featured by the rapid onset of action,long duration,fewer complications,strong safety and patients' great satisfaction.It is worth generalizing and applying clinically.

Methods Seventy four cases of acoustic neuromas treated microsurgically by suboccipital retrosigmoid transmeatus approach were analyzed retrospectively, including their clinical symptoms and characteristic image, the pathological anatomic relationships of facial nerve and tumor, microsurgical technique. Results Total resection of the tumor was achieved microsurgically in 72 cases, subtotal resection in 2 cases. Facial nerve was kept anatomic intact in 67(90.5%) of the patients. Intracranial end to end anastomosis of the facial nerve was performed in 4 cases. No patient died in this series. Conclusions Microneurosurgical technique is a safe and effective method for total resection of acoustic neuroma. It is key point for keeping facial nerve anatomic intact to understand the pathological anatomic relationships of facial nerve and tumor.

ObjectiveTo observe the therapeutic efficacy of warm needling plus acupoint injection in treating post-stroke urinary retention.MethodSeventy eligible subjects with post-stroke urinary retention were randomized into a treatment group of 35 cases and a control group of 35 cases. The treatment group was intervened by warm needling plus acupoint injection, while the control group was by warm needling alone. The relevant symptoms of urinary retention were observed before and after treatment.Result After 1-week treatment, the retention condition was improved in both groups, and the treatment group was significantly superior to the control group (P<0.05); The 2-week and 1-month follow-up studies showed that the retention condition in the treatment group was significantly better than that in the control group (P<0.05). The adverse events in the treatment group were significantly less than that in thecontrol group (P<0.05).ConclusionWarm needling plus acupoint injection can produce a satisfactory efficacy in treating post-stroke urinary retention and is worth application in clinic. However, this method still needs improving as its effect on initialurination and urination duration is not significant.
