Chinese Journal of Biochemical Pharmaceutics 2017;37(8):191-192
Objective To investigate the effects of lidocaine and methylene blue on the analgesia of the anal pain after hemorrhoids. Methods Using computer random way, to the hospital from January 2014 to October 2016 postoperative anal pain patients, 52 cases of hemorrhoids were randomLy divided into normal group and research group, 26 cases of each item, which the conventional pain processing, conventional group team to lidocaine and methylene blue, compared two groups of patients with analgesic effect and the incidence of adverse reactions. Results 1d, 3d, 5d and 7d were performed after surgery, and the VAS pain score of the study group was lower than that in the conventional group, and the results of the test were statistically significant (P<0.05). Statistical incidence of adverse reactions in both groups, found the team vomiting nausea, headache, dizziness and transient hypertension incidence of adverse reactions, significantly lower than the normal group, the difference between groups with the clinical inspection was statistically significant (P<0.05). Conclusion The postoperative anal pain, hemorrhoids application of lidocaine and methylene blue, can obtain satisfactory analgesia effect, operation method is simple, low incidence of adverse reactions, safe and reliable, and can use it as a clinical analgesic solution recommended applications.

The Journal of Clinical Anesthesiology 2017;33(5):438-441
Objective To discuss the agreement between pulse pressure variation of radial artery and pulse pressure variation of dorsal pedalartery in neurosurgery.Methods Twenty-five patients undergoing selective craniotomy under general anesthesia were enrolled.The following data were monitored and recorded respectively after tracheal intubation general anesthesia under different time:radial artery pulse pressure variability (PPV1) and dorsalis pedis pulse pressure variation (PPV2).Tidal volume was set to 8 ml/kg.Bland-Altman plots were created to assess agreement between PPV1 and PPV2.Results The mean differences and the limits of agreement between PPV1 and PPV2 are 20 min after induction of anesthesia 0.5% (-1.9%-2.8%), boneless flap instantly-0.5% (-3.8%-2.9%), Cut the dura mater instantly-0.1% (-3.2%-3.0%), and bone flap 0.1% (-2.4%-2.6%).Conclusion Dorsal pedal artery pulse pressure variation in neurosurgery craniotomy has certain guiding significance to the monitoring and management.

Objective To determine the effectiveness and clinical result of intraoperative monitoring of compound muscle action potential (CMAP) in avoiding nerve root impingement during lumbar spine intrapedical instrumentation. Methods Twenty-five cases were given intraoperative stimulus-evoked electromyographic monitoring. After anode of stimulating electrode was placed at the Kirschner wire inside the passage of pedicle screws, the integrity of the pedicle cortex was tested by stimulating each screw head and recording compound action potentials of relevant muscles. Results Stimulation at an intensity of 16.2 mA evoked a compound muscle action potential in one case and that at over 35 mA did in four cases. No neurologic deficits were found in any case intraoperatively or postoperatively. Conclusions Stimulating intensity below 10 mA needs rearranging screw site. A stimulation intensity of 10-20 mA indicates X-ray inspection and visual inspection to exclude any pedicle breaches. Stimulation thresholds above 20 mA can be regarded as safe threshold to monitor the nerve root impingement. Intraoperative electromyographic monitoring provides a real-time watch-dog for monitoring spinal nerve root injury during posterior lumbar instrumentation.

Objective To discuss the relationship between BMP-2 protein and possible mechanism and to compare the postive rate of two different imaging examinations in evaluating the epiphyseal plate involved by osteosarcoma.Methods Radiographic and MRI features of epiphyseal plate extension by osteosarcoma confirmed by pathology in 36 cases were analysed retrospectively.The expression of BMP-2 was detected with immunohistochemical SABC method in different part of specimen.Results The diagnostic accurate rate in evaluating the epiphyaeal plate extension from osteosarcoma by X-ray and MRI was 44.44% and 100% respectively.The positive reactive rate of BMP-2 in tumor body,epiphyseal plate soak district,normal epiphyseal plate and normal tissue nearby the tumor was 88.89%(32/36),99.44%(34/36),10.00%(1/10) and 20.00%(2/10) respectively.Conclusion MRI is more sensitive to radiography in evaluating the epiphyseal plate involved by osteosarcoma,the higher positive reactive rate of BMP-2 protein is correlated to the epiphyseal plate extension of osteosarcoma.

[Objective]To investigate the value of intra-operative somatosensory-evoked potential monitoring in surgery for thoracic spinal stenosis.[Method]Twenty-two patients with thoracic spinal stenosis underwent decompressive laminectomy surgery.The preoperative and intraoperative SPEs were recorded.The SEPs were analyzed with three indices:(1)SEPs wave pattern;(2)P40 latency;(3)P40-N50 amplitude.More than 50% decrease in SEPs amplitudes or more than 10% increase in latency was considered to be the warning threshold.[Result]Cases were classified into four groups according to preoperative SPEs wave pattern.Type Ⅰ inclued 2 cases whose SEPs monitoring had least meaning,and the spinal cord function remained unchanged postoperatively.4 cases with Type Ⅱ and the SEPs wave pattern were too unreliable to make analysis.Eleven cases in Type Ⅲ showed significant changes on SEPs,and most patients felt relief of symptom a week later.Type IV with 5 cases showed normal SEPs and all of them got well restored neurological function.[Conclusion]SEPs has good correlation with clinical outcomes.Its sensitivity,instant response and quantitative analysis make SEPs with great effectiveness in intraoperative monitoring on surgery of thoracic spinal stenosis.

Objective:To explore the difference in susceptibility to high-fat diet induced obesity in rats,as well as the changes of serum proteins. Method:Forty male SD rats were divided into basic group and high-fat diet group randomly. After 5w feeding DIO(diet-induced obesity)and DIO-R(diet-induced obesity resistance) rats were selected according to their body weight gain. The rats were sacrificed and the changes of serum proteins were screened using WCX2 proteomic chips made by American Ciphergen Biosystems. Results: DIO rats were significantly different from DIO-R rats in body weight,body-fat ratio,blood glucose and blood lipids. At the molecular weight range between 2 to 100 ku,the proteins with molecular weight of 7 945 and 9 513 were significantly expressed differently between DIO and DIO-R rats,and the proteins with molecular weight of 4496, 6152, 6267 were significantly expressed differently between DIO-R and control rats (the rats were fed basic diet). Conclusion:Different susceptibility to DIO or DIO-R was found in SD rats when they were fed high-fat diet. The differentially expressed serum proteins between DIO rats and DIO-R were observed,which might provide the basis for further isolation,purification and identification of these proteins.

Objective To observe the effect of segmented external dissection and internal ligation and leather bridge ligation plastic surgery in treatment of circumferential mixed hemorrhoids. Methods One hundred and twenty patients with circumferential mixed hemorrhoids were enrolled in this study, and they were divided into observation group and control group according to operation methods, with 60 cases in each group. The patients in two groups were treated with segmented Milligan-Morgan. The patients in observation group were treated with leather bridge ligation plastic surgery, and the patients in control group were treated with slit skin bridge plastic surgery. Postoperative complications and effect were observed. Results The pain scores on the first day and the third day after operation in two groups had no significant differences (P>0.05). On the seventh day after operation, the pain scores in observation group was significantly better than that in control group (P < 0.01). After operation, the number of edema and anal stenosis in two groups had no significant differences (P>0.05). The number of broken leather bridge in observation group was significantly shorter than that in control group (P<0.01). The healing time in the observation group was significantly shorter than that in control group:(24.0 ± 3.6) d vs. (29.6 ± 4.70) d, t =- 6.05, P<0.01. Conclusions Segmented external dissection and internal ligation and leather bridge ligation plastic surgery in treatment of circumferential mixed hemorrhoids is safe and easy to operate, and it has a significant clinical effect.
