Objective To investigate the effect of single operation Mammotome system on breast benign tumor patients.Methods 86 cases of benign breast cancer patients admitted from Jan.2011 to Dec.2015 were divided into the control group (43 cases) and the observation group (43 cases) according to the random number table method.The control group were treated by traditional breast lesion resection and the observation group were treated by single operation of Mammotome system.The mean time of operation,the average blood loss and the size of surgical scar were recorded.The number of patients with deformity of breast and complications was recorded.The satisfaction of the two groups was evaluated by questionnaire.The recurrence rate of the two groups was statistically analyzed.Results The average operation time of the observation group was significantly shorter than that of the control group,and the scar size was significantly smaller than that of the control group (P<0.05).The deformity rate of the observation group was 0%,significantly lower than that of the control group (11.6%).The satisfaction rate was 97.7% in the observation group,significantly higher than that of the control group (83.7%,P<0.05).The postoperative complication rate was 4.7% in the observation group,significantly lower than that of the control group (18.6%,P<0.05).There was no recurrence in the two groups during 6 months of follow-up.Conclusion The application of single breast operation Mammotome treatment for benign breast tumor has the advantages of simple operation,shorter operation time,less intraoperative blood loss and surgical scars.It also can reduce the postoperative complications,keep breast shape,reduce the recurrence rate,so as to improve the patient satisfaction.

To provide the anatomical information for auricle replantation. Methods From March, 2016 to March, 2019, a total of 25 fresh adult cadaveric head were used, 20 of these specimens were perfused with plastic and eroded to be vascular cast mold, 5 specimens perfused with red latex for anatomy, then observed the origin, course, diameter and arteries anastomose between branches of the posterior auricular artery (PAA) and superfi-cial temporal artery (STA). Results The main blood supply to the auricle were auricle branches of PAA and STA. The auricle branches of PAA and STA both divided into superior, intermedius and inferior branches, and distributed in the auricle posterior surface and anterior surface, respectively.The auricle branches of PAA running across ear car-tilage, distributed in the anterior surface, and anastomosed with auricle branches of STA. The diameters of these branches at the initiating portion were 0.2-0.8 mm. Eighty percent of blood supply to earlobe was from the inferior branches of PAA, and 20% from the STA. Conclusion The auricle branches of PAA played an important role to the auricle replantation.The auricle branches of PAA should be the firstly selected vessle in operation, and the auricle branches of STA be the second choice.

Objective:To explore the clinical effects of endoscopic sinuvertebral nerves neurotomy for discogenic low back pain.Methods:Based on the anatomical research of sinuvertebral nerves, a total of 40 patients, including 9 males and 21 females aged 35±10 (24-55) years, with single-segment discogenic low back pain were treated with endoscopic sinuvertebral nerves neurotomy in our hospital from July 2018 to February 2019. The operating section included 4 cases of L 3,4 (10.0%, 4/40), 31 cases of L 4, 5 (77.5%, 31/40), and 5 cases of L 5S 1 (12.5%, 5/40). The preoperative visual analogue scale (VAS) score was 4.5±0.9 with the preoperative Oswestry disability index (ODI) score 49.7%±14.0%. For diagnostic nerves block, lidocaine (0.1-0.3 ml of 0.05 g/L) was successfully injected into the intersection of the lateral edge of the bilateral pedicle projection and the upper edge of the intervertebral disc projection. The initial segment of the sinuvertebral nerves was destroyed by a radiofrequency blade or a nerve dissector after bilateral percutaneous transforaminal endoscopic. All cases were followed up at 1, 3, 6 and 12 months after surgery, observing the changes in VAS and ODI. Results:Filamentous lumbar sinuvertebral nerve was observed under endoscope with its main trunk tranversed into the spinal canal against the intervertebral disc. The deputy trunk crossed at the posterolateral edge of the intervertebral disc and entered the intervertebral disc or the posterior edge of the vertebral body. By moving along with postcentral branches of spinal artery, the main trunk of sinuvertebral nerve was with tension and was capable of moving with the nerve root. In spite of moving the working channel along the main trunk of the sinuvertebral nerve laterally, the starting point of the sinuvertebral nerve at the ventral ganglion could be observed. All 40 patients successfully completed the sinuvertebral nerve destruction. The VAS was reduced to 1.7±0.9, 1.3±0.9, 1.2±0.8, 1.3±0.7 at 1, 3, 6 and 12 months after sugery respectively, which were significantly lower than those at pre-operation ( F=116.7, P=0.00). The improvement rate of VAS in 40 cases was 68.9%± 17.1% (33.3%-100.0%) at 12 months after operation. The VAS score in 6 cases was higher at 12 months after surgery than that preoperatively ( t=4.2, P=0.48), namely 1 case of L 3, 4, 2 cases of L 4, 5, and 3 cases of L 5S 1. In all cases, the ODI was reduced to 18.3%±5.2%, 14.5%±4.3%, 13.6%±3.7%, 12.8%±3.0% points at 1, 3, 6 and 12 months after surgery respectively, which were significantly lower than those before surgery ( F=237.7, P=0.00). The improvement rate of ODI was 72.0%±11.6% (33.3%-88.9%) at 12 months after surgery in all cases. Conclusion:The destruction of sinuvertebral nerve after transforaminal endoscope could improve the pain and function in patients with discogenic low back pain at L 3,4 and L 4, 5 segments within 12 months. For patients with discogenic low back pain at L 5S 1 segment, the clinical effects could be better within 6 months.

A new series of 2-(5-methyl-2,3-dioxoindolin-1-yl)acetamide derivatives were synthesized and evaluated for their anticonvulsive activity in a pentylenetetrazole (PTZ)-evoked convulsion model and antidepressant activity in the forced swimming test (FST) model. Eleven synthesized compounds were found to be protective against PTZ-induced seizure and showed the anticonvulsant activity. In addition, four of the synthesized compounds (4l, 4m, 4p and 4q) showed potent antidepressant-like activity. Among these compounds, compound 4l was found to have the most potent antidepressant-like activity, and significantly reduced the duration of immobility time at 100 mg/kg dose level when compared to the vehicle control, which is similar to the reference drug fluoxetine.

Objective:
To observe the location and the distribution of distal 1/3 segment of the second dorsal metacarpal artery, the finger web artery and the dorsal digital artery, and to provide anatomical data for repairing the soft tissue defect on the hand with bilobed or multi-lobed micro-flap with second metacarpal dorsal artery-dorsal digital artery.
Methods:
From June, 2018 to March, 2019, 34 fresh adult upper limb specimens were selected. The radial and ulnar arteries were perfused with red latex in 24 specimens. The radial and ulnar arteries were infused with cast materials to make cast specimens in 10 specimens. The location and distribution of the distal 1/3 segment of the second dorsal metacarpal artery, the finger web and the dorsal digital artery were observed.
Results:
The distal 1/3 segment of second dorsal metacarpal artery extended (4±1) cutaneous branches, and continued to become the finger web artery at the plane of the articular surface. The length of the finger web artery was (2.5±0.6) cm, and there were 4 types anastomic methods of communication with arteries. The second dorsal metacarpal artery extended 2 finger dorsal artery to the proximal dorsal skin of the middle finger and index finger. The length of dorsal digital artery was 2.6±0.4 cm and the diameter was 0.2±0.1 mm. Four to 6 micro-cutaneous branches were extended and consistent with the nearby skin cutaneous branches.
Conclusion
The distal segment of the second dorsal metacarpal artery and the dorsal digital artery is anatomically constant. The distal segment of the second dorsal metacarpal artery and dorsal digital artery are the pedicle for the design of the bilobed flap of middle finger and index finger to repair small soft tissue defect on the thumb and purlicue.
