【Objective】 To evaluate the curative effect of posterior atlantoaxial joint release and internal fixation in treating unstable craniocervical junction malformation （UCVJM）. 【Methods】 This study retrospectively enrolled 31 patients with UCVJM， who received posterior atlantoaxial joint release and internal fixation between January 2015 and December 2018. The pre- and postoperative changes of the Japanese Orthopaedic Association （JOA） scores， the cervicomedullary angle （CMA）， the atlantodental interval （ADI） and the height above the Chamberlain line of the odontoid （H） were traced to evaluate whether clinical symptoms， compression of spinal cord， horizontal and vertical dislocation of atlantoaxial were improved postoperatively. 【Results】 The average operation duration， bleeding during operation and the average days of hospitalization were （168.38±38.21）min， （147.09±59.84）mL， and （9.54±2.81） days， respectively. None of the patients had vertebral artery or spinal cord injury during operation. JOA score， ADI， H， and CMA were （11.94±1.37） points， （2.72±1.08）mm， （3.03±0.78）mm， and （145.35±8.00）° respectively on the 6th days after operation compared with the preoperative （9.94±1.26） points， （4.96±1.60）mm， （6.89±1.36） mm and （122.16±9.58）°， with statistical differences， which indicated all indexes were improved （all P<0.001）. During 6-25 months’ follow-up， there was no internal fixation looseness or displacement and JOA score was increased to （13.16±1.19） for all the patients in the last follow-up （all P<0.001）. 【Conclusion】 The posterior atlantoaxial joint release combined with internal fixation is safe and effective for patients with UCVJM.

【Objective】 To discuss and summarize the choice of the operation plan and evaluation of curative effect of spasmodic cerebral palsy. 【Methods】 Clinical data of 80 patients with spastic cerebral palsy treated by neurosurgery in The First Affiliated Hospital of Xi’an Jiaotong University were collected retrospectively and analyzed statistically. Eighty patients were followed up for 12 to 52 months, with an average follow-up of 21.3 months. The muscle tension grading, spasm index, range of motion, Holden walking ability and postoperative complications were compared one year after surgery. 【Results】 Totally 64 cases received selective posterior rhizotomy (SPR) combined muscle strength muscle tension adjustment method (MMA) and 16 cases selective peripheral neurotomy combined muscle strength muscle tension adjustment method. The grade and spasm index of muscle tension decreased significantly one year after operation (P<0.001). The range of joint motion and Holden walking ability were significantly improved (P<0.001). Transient urination disorder occurred in two cases (2.5%), and limb sensation disorder in two cases (2.5%), all of which were improved within three months. Weakness of dorsiflexion of foot in one case (1.25%). 【Conclusion】 Selective partial neurotomy and muscle tension adjustment is a safe and effective surgical method to treat spasmodic cerebral palsy. Real-time evaluation of muscle tension and ankle clonus changes during the operation is an important factor to ensure the postoperative efficacy.

【Objective】 To compare the application of modified selective posterior rhiotomy of spinal nerve with traditional rhiotomy in the treatment of spastic cerebral palsy and to evaluate the efficacy and complications of the two surgical methods. 【Methods】 The clinical data of 52 patients with spastic cerebral palsy were analyzed retrospectively. Among them 23 cases were treated with traditional selective posterior rhiotomy and the remaining 29 cases with modified selective posterior rhiotomy. Operation time, amount of blood loss, proportion of root after spinal nerve amputation, postoperative complications, spasm index, ankle clonus, and Holden walking ability at 1 year after operation were compared between the two groups. 【Results】 The operation time of modified selective posterior rhiotomy was longer than that of conventional surgery (P<0.05). There was no difference in intraoperative blood loss, postoperative complications, spasm index one year after surgery, or Holden walking ability between the two groups (P>0.05). The proportion of root was smaller in the modified group than in the traditional group (P<0.05). The improved group was superior to the traditional group in the disappearance of ankle clonus (P<0.05). 【Conclusion】 Modified selective posterior rhiotomy has more advantages in eliminating ankle clonus. It is a safe and effective surgical improvement method to evaluate the changes of muscle tension and ankle clonus to quantitatively cut the posterior root of spinal nerve during the operation. This can reduce the proportion of the posterior root of spinal nerve during the operation, and keep the anatomical and functional basis for reducing the occurrence of surgical complications.

The corona virus disease 2019 (COVID-19) caused by the new coronavirus (SARS-CoV-2) has spread rapidly around the world,posing a serious threat to the public"s health. As of September 30,2020,the number of infected people in the world has reached 33 million,causing more than 1 million deaths. Normalized nucleic acid detection methods based on lab have long turnaround time and high cost. Therefore,there is an urgent need to develop a convenient method to detect SARS-CoV-2,so as to achieve rapid testing and timely control of the epidemic when resources are limited.This review summarizes the point-of-care testing (POCT) methods developed for SARS-CoV-2 in terms of extraction,amplification and detection,and briefly introduces commercial POCT instruments that integrate these three steps,in order to provide references for emergency response and rapid deployment of COVID-19 and other emerging infectious diseases.

Objective To explore the clinical application of reduction anaplasty trough a minor pre-auricular incision.Methods A retrospective analysis of 89 patients with wide zygomatic arch treated with reduction anaplasty through pre-auricular incision from 2012 to 2016 in our hospital had been studied.Through a short incision in front of ear,zygomatic arch at the most narrow part,located about 5 cm in front of temporomandibular joint,was completely transected,whereas the junction of malar and zygomatic bone was drilled to make a greenstick fracture.No dissection of zygomatic ligament was perforemed.The dissected zygomatic arch was then pressed down and adjusted into a appropriate position.In the case of the protrusion of zygomatic body,the protrusion part could be reducted using grinding ablation.Results All the patients were followed up for 3 months to 5 years.The results were satisfactory,no serious complications were found,and the facial tissue did not show obvious ptosis.Postoperative numbness occurred on the left side in one patient and recovered spontaneously after two months.Conclusions Reduction anaplasty trough a minor pre-auricular incision is a simple,safe and effective approach for wide zygomatic arch,which could avoid facial tissue ptosis.

Objective:To explore the effect of laparoscopic minimally invasive on anorectal dynamics and serum carcino-embryonic antigen (CEA) and carbohydrate antigen 724 (CA724) in patients with rectal cancer.Methods:38 cases of rectal cancer patients were selected as the research group from March 2014 to March 2016 and 40 cases of non neoplastic intestinal polyps as control group,Preoperative anorectal dynamics index (anal resting pressure (ARP),rectal resting pressure (RRP)and anal maximal contraction pressure (MSP),rectal maximum tolerated volume (MTV) of two groups were compared,Preoperative and 3 d,1,2 weeks after operation of serum CEA and CA724 levels were detected in the research group and the clinical curative effect was observed.Results:There was no significant difference of ARP,RRP,MSP,MTV before operation in research group compared with the control group(P＞0.05),and was significantly reduced 2,4 weeks after operation(P＜0.05),then gradually restored,and basically recovered to the preoperative level 12 weeks after operation.There was no significant difference of serum CEA and CA724 levels 3 d after operation compared with preoperative in research group (P＞0.05),and were significantly lower 1,2 weeks after operation compared with preoperative (P＜0.05).The clinical effective rate was 65.8％.Conclusion:Efficacy of laparoscopic minimally invasive in treatment of rectal cancer is effective,can effectively reduce the levels of tumor markers,although there are some influence on anorectal dynamics,but it can be returned to normal in the short term.

Objective To study intraoperative neural electrophysiological monitoring applied in lumbosacral spinal cord tumor resection.Methods We retrospectively reviewed the clinical data of 212 patients undergoing lumbosacral spinal cord tumor resection with or without intraoperative neural electrophysiological monitoring in our hospital.The patients were divided into two groups:124 patients in the monitored group received intraoperative neural electrophysiological monitoring while 88 ones in the control group did not.The monitoring was performed by recording the cortical somatosensory evoked potential (CSEP),dermatomal somatosensory evoked potential (DSEP) and electromyography (EMG).The patients were followed up for 3-6 months and their postoperative outcome was analyzed.Results There were significant differences in the outcome (P <0.05),but no difference was found in the incidence of complications between the monitored group and the control group.The sensitivity of CSEP +DSEP+EMG was 100%,and the specificity was 55.9% in the former group.Conclusion Combined monitoring with CSEP,DSEP and EMG during lumbosacral spinal cord tumor resection is valuable in protecting the spinal nerve roots and ensuring better operation safety.

Objective To compare the modified expanding suspended laminoplasty and posterior pedicle screw fixation applied in lumbar intraspinal tumors and evaluate operation,complications,postoperative neurofunctional improvement and lumbar lumbar stability in the two groups.Methods We made a retrospective analysis of the clinical data of 1 14 cases of lumbar intraspinal tumors, including 66 cases of modified expanding suspended laminoplasty and 48 cases of posterior pedicle screw fixation.We compared the operation time,operation bleeding volume,and incidence of postoperative cerebrospinal fluid leakage in the two groups.We also analyzed the lumbar instability and spinal cord injury score standard by the Japanese Orthopedic Association (JOA)between the two groups at 3,6, 12,and 24 months after operation.Results The results of modified expanding suspended laminoplasty group were significantly better than those of posterior pedicle screw fixation group in operation time, operation bleeding volume and incidence of postoperative cerebrospinal fluid leakage (P < 0.01 ).The lumbar instability did not significantly differ between the two groups (P >0.05).At 3,6 or 12 months after the operation, changes in the increase of JOA score of the two groups had no significant difference (P > 0.05 ).However,24 mouths after the operation,the group of posterior pedicle screw fixation had significantly improved JOA score compared with that in the modified expanding suspended laminoplasty group.Conclusion Both the modified expanding suspended laminoplasty and posterior pedicle screw fixation have a favorable outcome of postoperative lumbar instability and neurofunction.And posterior pedicle screw fixation is superior to modified expanding suspended laminoplasty in improving neurofunction.

Objective To investigate the indications,surgical principles and advantages and disadvantages of microsurgery of intra-spinal tumor via the quadrant pathway.Methods We made a retrospective analysis of the clinical data of patients with spinal canal tumors treated via the quadrant pathway from October 2014 to July 201 5. Results Totally 1 6 patients were included.Their tumors were fully removed by microscopic resection,in which there were three epidural cases,twelve subdural extra-medullar cases,and one intra-medullar case.In terms of stage,there were three cases of cervical segment (C3 - C7 ),four cases of thoracic (T1 - T10 ),nine cases of thoracic and lumbar ones (T1 1 - S2 ). In pathology, there were nine cases of neurilemmoma, two cases of neurofibroma,four cases of meningeal tumor and one case of neuroepithelial cyst.The postoperative symptoms and signs of the patients were significantly improved,and no recurrence or complications occurred in the follow-up 2-10 months.Conclusion Quadrant pathway can be used in removing spinal epidural and subdural tumor,which is shorter than two vertebral segments in length,and the cross-sectional area is less than 2/3 of the spinal cord. However,surgery with extensive adhesion and intra-medullary lesions should be performed carefully,and the surgical techniques are more demanding and a longer learning curve is needed.
