Injury of the posterior pelvic ring can easily be caused by high-energy impact,and sacroiliac joint dislocation is the most common.The sacroiliac joint,as the hub of load transfer between the trunk and lower extremities,is essential to maintain the stability of the posterior pelvic ring,and once dislocation occurs,restoring the stability of the posterior pelvic ring by timely surgery is necessary.The current surgical approaches for the internal fixation of sacroiliac joint are mainly divided into anterior approach and posterior approach.The choice of the surgical approach directly affects the exposure of the surgical field,the stability of internal fixation and the prognosis of patients;therefore,it is particularly important to select the appropriate surgical approach and fixation method.In this paper,we briefly review the selection of sacroiliac joint fixation points,surgical approaches and postoperative complications.

Post-traumatic stress disorder(PTSD),as a mental disorder disease,can seriously damage the physical and mental health and social functioning of patients.Physical therapy is increasingly being used in research on the treatment of PTSD due to its ability to directly target specific brain regions and improve the core symptoms of PTSD.This review categorizes on physical therapy for PTSD into two categories:non-invasive physical therapy and invasive physical therapy.Non-invasive physical therapy methods included electroconvulsive therapy,transcranial direct current stimulation,transcranial magnetic stimulation,and the Flexyx neurotherapy system.Non-invasive physical therapy had the advantages of safety,convenience,and simple operation.However,their stimulation accuracy was limited.Invasive physical therapy methods included deep brain stimulation and stellate ganglion block.Invasive physical therapy had the advantages of precise stimulation,fewer adverse reactions.However,there were surgical risks,high operational difficulty,and high treatment costs.In addition,potential physical therapy methods included transcranial alternating current stimulation,magnetic seizure therapy,and vagus nerve stimulation,which were currently in the theoretical research stage.This study discussed the mechanism of action,therapeutic parameters,clinical efficacy,adverse effects and the latest forms of technology of the above physical therapy methods,so as to provide reference for the treatment of PTSD.

Objective@#In this research, the influence of breviscapine on anxiety, fear elimination, and aggression and the potential mechanism was investigated. @*Methods@#Anxiety and locomotion were analyzed by elevated plus maze and open field test in mice. Bussey-Saksida Mouse Touch Screen Chambers were used to perform fear conditioning. Territorial aggression was assessed by resident intruder test. Protein levels were evaluated by Western blot. Breviscapine improved fear-extinction learning in BALB/cJ mice. @*Results@#Breviscapine at 20–100 mg/kg increased center cross number, total distance traveled, and velocity in a dose-dependent manner. On the other hand, breviscapine at 20–100 mg/kg decreased the immobility time in open field test. In addition, breviscapine at 20–100 mg/kg increased the ratio of time on the open arm, time on the distal parts of the open arm, and total distance traveled in elevated plus maze. Breviscapine at 100 mg/kg increased the average attack latency and decreased the number of attacks over the last 3 days of resident intruder test. In hippocampus, protein levels of postsynaptic density protein-95 and synaptophysin were elevated by breviscapine at these three doses. @*Conclusion@#The administration of breviscapine alleviates fear extinction, anxiety, and aggression, while increases locomotor in a dose-dependent manner, which might be associated with its influence on synaptic function.

Objective: To investigate the clinicopathological features and possible mechanisms of burned-out testicular germ cell tumors. Methods: The clinical and imaging data, histology and immunophenotypic characteristics of three cases of burned-out testicular germ cell tumors diagnosed at the Ruijin Hospital, Medical College of the Shanghai Jiaotong University, from 2016 to 2020 were retrospectively analyzed. The relevant literature was reviewed. Results: The mean age of the three patients was 32 years. Case 1 had an elevated preoperative alpha-fetoprotein level (810.18 μg/L) and underwent "radical pancreaticoduodenectomy and retroperitoneal lesion resection" for a retroperitoneal mass. Postoperative pathology showed embryonal carcinoma, which needed to exclude gonadal metastasis. Color Doppler ultrasound showed a solid mass of the right testis, with hypoechoic lesion and scattered calcification in some areas. Case 2 was a "right supraclavicular lymph node biopsy specimen." Chest X-ray showed multiple metastases in both lungs. The biopsy showed metastatic embryonic carcinoma and bilateral testicular color Doppler ultrasound revealed abnormal calcifications in the right testicle. Case 3 showed a cystic mass of the right testis with calcification and solid areas. All 3 patients underwent radical right orchiectomy. Grossly, borders of the testicular scar areas were well defined. Cross sectioning of the tumors showed a gray-brown cut surface and single focus or multiple foci of the tumor. The tumor maximum diameter was 0.6-1.5 cm. Microscopically, lymphocytes, plasma cells infiltration, tubular hyalinization, clustered vascular hyperplasia and hemosiderin laden macrophages were found in the scar. Atrophic and sclerotic seminiferous tubules, proliferation of clustered Leydig cells and small or coarse granular calcifications in seminiferous tubules were present around the scar. Seminoma and germ cell neoplasia in situ were seen in case 1, germ cell neoplasia in situ was seen in case 2 and germ cells with atypical hyperplasia were seen in case 3. Immunohistochemistry showed that embryonic carcinoma expressed SALL4, CKpan(AE1/AE3) and CD30, seminoma and germ cell tumor in situ expressed OCT3/4, SALL4 and CD117, and spermatogenic cells with atypical hyperplasia expressed CD99 and SALL4. The Ki-67 positive index was about 20%, while OCT3/4 and CD117 were both negative. Conclusions: Burned-out testicular germ cell tumors are rare. The possibility of gonad testicular metastasis should be considered first for extragonadal germ cell tumor. If fibrous scar is found in testis, it must be determined whether it is a burned-out testicular germ cell tumor. The burned-out mechanisms may be related to the microenvironment of tumor immune-mediated and local ischemic injury.

Acute-on-chronic liver failure (ACLF) is a potentially reversible entity that occurs in patients with chronic liver disease accompanied with or without cirrhosis and is characterized by extrahepatic organ failure and high short-term mortality. Currently, the most effective treatment method for patients with ACLF is liver transplantation; therefore, admission timing and contraindications must be emphasized. The function of vital organs such as the heart, brain, lungs, and kidneys should be actively supported and protected during the liver transplantation perioperative period in patients with ACLF. Focusing on the anesthesia management level during anesthesia selection, intraoperative monitoring, three-stage management, prevention and treatment of post-perfusion syndrome, monitoring and management of coagulation function, volume monitoring and management, and body temperature monitoring management for liver transplantation should strengthen anesthesia management. Additionally, standard postoperative intensive care treatment should be recommended, and grafts and other vital organ functions should be monitored throughout the perioperative period to promote early postoperative recovery in patients with ACLF.

OBJECTIVE@#To investigate the correlation between aldehyde dehydrogenase 2 (ALDH2) rs671 polymorphisms and chemotherapy-induced nausea and vomiting (CINV).@*METHODS@#A total of 90 Chinese patients with malignant tumors receiving chemotherapy for the first time were recruited in this study. The occurrence of CINV was observed within 120 h after treatment with docetaxel and cis-platinum chemotherapy (DP regimen). The data of the patients (including age, gender, tumor stage, habitual alcohol consumption, motion sickness, morning sickness, and average sleep time prior to chemotherapy) were collected through a questionnaire. ALDH2 rs671 polymorphisms of the patients were analyzed using a multiple single nucleotide polymorphism genotyping, and the Hardy-Weinberg equation was used for genetic linkage analysis. The correlations between the factors including ALDH2 rs671 polymorphisms and the occurrence of CINV were analyzed.@*RESULTS@#The incidence of CINV was 48.9% among the patients receiving their first chemotherapy with DP regimen. Univariate analysis indicated that the genetic polymorphisms of ALDH2 rs671 were significantly correlated with the occurrence of CINV (P < 0.05). Multivariate logistic analysis indicated that ALDH2 rs671 mutation (OR: 3.019, 95% CI: 1.056-8.628, P < 0.05) and average sleep time prior to chemotherapy no longer than 6 h (OR: 2.807, 95% CI: 1.033-7.628, P < 0.05) were risk factors for CINV in patients with malignant tumors receiving the first chemotherapy with DP regimen.@*CONCLUSION@#ALDH2 gene mutation at rs671 is a risk factor contributing to the occurrence of CINV, and understanding of the underlying mechanism may help to more effectively control the occurrence of CINV.

The SF-36 score of the minimally invasive group 61.48±9.50 at the last follow-up was higher than that of the navigation open group 52.51±6.99 and the open group 53.48±7.66, and the difference was statistically significant ( F=18.97, P<0.001). In the same group, the VAS score, ODI score and SF-36 score at each follow-up time after surgery were statistical differences compared with those before surgery ( P<0.05). Postoperative follow-up CT showed that the fusion rate of the minimally invasive group was 94.0% (63/67), the navigation open group was 93.5% (29/31), the open group was 93.1% (54/58), and the difference between the three groups was not statistically significant (χ 2=0.05, P=0.978). The success rate and accuracy of one-time nail placement in the minimally invasive group and the navigation open group were higher than those in the open group, the difference was statistically significant (χ 2=17.17, P<0.001; χ 2=15.49, P=0.040). Dural rupture occurred in 1 patient in the minimally invasive group and 2 patients in the open group. The drainage and condition changes were closely observed after surgery. All patients were successfully extubated after surgery without complaining of other discomfort. One patient in the minimally invasive group had endplate destruction and mild intervertebral collapse during postoperative follow-up. There was 1 case of incisional fat liquefaction in each of the navigation open group and the open group. Subgroup analysis of the results of the three groups were roughly the same as the overall results. Conclusion:MIS-TLIF in the Zista channel assisted by navigation is a safe, effective, and worthy of promotion minimally invasive lumbar fusion surgery with the advantages of less trauma and faster recovery in the treatment of different types of lumbar spinal stenosis.

Objective To evaluate the clinical efficacy of the minimally invasive treatment with Zista system for lum-bar spinal stenosis. Methods April 2016 to October 2017, 45 patients with lumbar spinal stenosis (2 or 3 segments) were retro-spectively collected, including 21 males and 24 females. Age 50-74 years, average 62.5 ±11.2 years, which were divided into mini-invasive surgery group and open surgery group. In the mini-invasive group, 19 cases were treated with mini-invasive decompres-sion and intervertebral fusion internal fixation through Zista channel, including 14 cases with two segments and 5 cases with three segments. 26 cases were treated with traditional open surgery, 17 cases in two sections and 9 cases in three sections. The Japanese Orthopaedic Association score (JOA) and visual analogue scale (VAS) were used to assess the clinical effect postoperatively. The change of spinal canal in the mini-invasive group was assessed by lateral recess angle. Results All of the 45 operations had been completed successfully. The average operation time in mini-invasive surgery group was 240 ± 15 min (range, 230-310) for 2 seg-ments and 320 ± 15 min (range, 320-370) for 3 segments. The average operation time in open surgery group was 255 ± 15 min (range, 210-300) for 2 segments and 315±20 min (range, 330-390) for 3 segments, there was no significant difference between two groups. The intraoperative blood loss in mini-invasive surgery group was 220±25 ml (range, 190-310) for 2 segments and 340±30 ml (range, 280-410) for 3 segments. The intraoperative blood loss in open surgery group was 550 ± 25 ml (range, 500-730) for 2 segments and 840 ± 20 ml (range, 750-920) for 3 segments, the bleeding volume of the open surgery group was more than that of the mini-invasive group. All patients were followed up, and the follow-up time was 7.3±3.2 months (range, 3-12 months) in mini-invasive surgery group and 8.1 ± 2.6 months (range, 3-12 months) in open surgery group respectively. The VAS score of low backpain and lower limb pain in the two groups was decreased 4.2 and 5.4 in mini-invasive group, 4.7 and 5.1 in open surgery group at 3 months after operation. The average JOA score of the two groups increased 13.3 in mini-invasive group and 12.7 in open surgery group at 3 months after the operation. The latera recess angle in mini-invasive group between preoperation and postoperation was significantly different. No incisional infection, implant loosening, discitis and leakage of cerebrospinal fluid were found. Conclu-sion Mini-invasive decompression and internal fixation through Zista channel for lumbar spinal stenosis is a safe, effective and minimally invasive method of operation with the characteristics of short operation time, less intraoperative blood loss and low com-plications.

This study aimed to estimate the prevalence of and identify the factors influencing female sexual dysfunction (FSD) among Chinese nurses. A cross-sectional survey was conducted from March 2013 to May 2014 among 6 hospitals in Suzhou, China. In total, 2,030 married female nurses were included in the analysis. Data on the sociodemographic, lifestyle, and self-reported health status of the participants were collected, and the participants were asked to complete the Chinese version of the 19-item Female Sexual Function Index (FSFI) questionnaire. In total, 1,035 (50.99%) participants were found to have FSD. Logistic regression analysis showed that increasing age and higher body mass index, lower salary, and poor/very poor self-reported health status were risk factors for FSD; however, regular social activity and physical exercise were protective factors for FSD. The findings of this study suggest that further interventional studies are warranted to study the sexual health among Chinese nurses in detail.

Objective Patients with mild or moderate blepharoptosis performed with double eyelid operation only will lead to high complication rates,such as eyelid crease disappearance,unphysiological appearance.In such cases,utilizing levator aponeurosis can create more physiological double eyelid and correct blepharoptosis in the meantime.Methods Levator aponeurosis is utilized as "connecting tissue" to transmit dynamic "motor power" of levator muscle to upper eyelid.Levator advancement was performed at the same time to correct blepharoptosis.Results A total of 74 patients (125 eyes) were operated on in this study.117 eyes (93.6%) showed adequate blepharoptosis correction results,8 eyes (6.4%) showed inadequate correction results.Sixty six cases (89.2%) showed good symmetry results,5 cases (6.8%) showed fair results,3 cases (4%) showed bad symmetry results.One hundred and fourteen eyes (91.2%) showed stable crease,11 eyes (8.8%) showed fair results,no disappearance result was observed in this study.No scar hypertrophy or blepharoptosis on the upper eyelid was encountered.Conclusions This new technique uses pretarsal levator aponeurosis to connect levator muscle and upper eyelid skin,it transmits the dynamic power of the levator muscle to the lid skin directly,which created palperbral crease more anatomically and physiologically.In the meantime,levator advancement can be performed to correct blepharoptosis.Furthermore,"skin adhesion" is formed between levator aponeurosis and dermis in a plane planar manner,allowing for more stable palperbralpalpebral crease and more preserved,and preserving orbicularis oculi in situ,leaving no gap in skin and thus reducing eyelid scar formation.

OBJECTIVE@#To observe the effect of nuclear transcription factor-κB (NF-κB) on cerebral edema in rats with traumatic brain injury (TBI).@*METHODS@#Male SD rats with fluid percussion injury (FPI) were selected. After separation and culture, rats' astrocytes all suffered FPI. The expression of NF-κB and the water content were detected at the animal and cellular levels, while the activity of NOX was evaluated at the cellular level.@*RESULTS@#According to the results, the positive expression of NF-κB and expression of mRNA were significantly increased and the water content was increased for rats after TBI, while NF-κB inhibitor BAY11-7082 could significantly reduce the effect of TBI. 1 and 3 h after FPI of astrocytes, the activation of NF-κB was increased and BAY 11-7082 could significantly improve the injury-induced swelling of astrocytes. After the injury of astrocytes, the activity of NOX was also increased, while BAY 11-7082 could reduce the activity of NOX.@*CONCLUSIONS@#The results show that the activation of NF-κB in astrocytes is a key factor in the process of cerebral edema after TBI of rats.
