Major depressive disorder (MDD) is a mental disorder with high prevalence,morbidity and recurrence rate.The treatment goal of acute stage is to achieve remission,which means asymptomatic.However,clinical treatments and studies found impairment of psychosocial functioning still exists even after remission,which means incomplete recovery.As is known,the normalization of psychosocial functioning is essential to the recovery and the recurrence prevention of MDD.In order to provide reference and guidance for the clinical treatments and studies,we reviewed the related studies and found many kinds of factors influencing the restoration of psychosocial functioning,including demographic factors,diseases related factors,psychological factors,social factors and therapeutic approaches.However,few interior studies focused on the recovery of MDD,and the results of foreign studies were inconsistent,while the understanding of how those factors influence the recovery of MDD is not clear enough.In order to make the characteristics of psychosocial functioning recovery and mechanisms of the influencing factors clear,more in-depth studies should be done in the future.

Femoral intertrochanteric fracture is one of the common types of fractures in the elderly. With the general improvement of medical and living standards, the number of elderly people is increasing, and the problem of osteoporosis has also become relatively prominent. Therefore, low violence can usually cause fractures in this area of the elderly, which has a significant negative impact on the quality of life of elderly patients. With the further development of medical technology and internal fixation materials, the emergence of proximal femoral nail antirotation(PFNA) has greatly improved the treatment effect of femoral intertrochanteric fractures in elderly patients. However, with the increasing number of patients treated, internal fixation failures have gradually been reported. In recent years, proximal femoral biomimetic intramedullary nail(PFBN) has been reported to have good clinical efficacy. Therefore, this article mainly elaborates on the theoretical basis, design characteristics, biomechanics, and clinical efficacy research of PFBN, providing more reference for the clinical treatment of femoral intertrochanteric fractures in elderly patients in the future.

Objective:To investigate the difference of functional connectivity(FC) between the habenula and other brain regions in the patients with first-episode current depression (fMDD) and remitted depression (rMDD).Methods:Thirty-five patients with first-episode current depression (fMDD), 35 patients with remitted depression (rMDD) and 30 healthy controls (HC) matched with gender, age and education years were scanned by resting-state fMRI. Hamilton Depression Scale (HAMD 17) was used to assess the severity of the patients. After preprocessing, seed-based FC analysis was performed on the habenula. Pearson correlation analysis was performed between the FC values and HAMD 17 and duration of disease. Results:(1) Compared with the HC group, FC decreased between the habenula and left middle occipital gyrus(l-MOG) in fMDD group (x, y, z=-48, -84, 3, t=-4.335, P<0.05), while FC increased between the habenula and left supramarginal gyrus (x, y, z=-66, -30, 36, t=4.876, P<0.05), left superior frontal gyrus(l-SFG) (x, y, z=-6, -33, 51, t=4.402, P<0.05), left inferior parietal lobe(l-IPL)( t=3.300, P<0.05) and right inferior parietal lobe(r-IPL) ( t=3.557, P<0.05) in fMDD group. Compared with the HC, FC decreased between the habenula and l-MOG (x, y, z=-48, -84, 3, t=-4.321, P<0.05) and left thalamus (x, y, z=-9, 3, 3, t=-3.971, P<0.05) in rMDD group, while FC increased between the habenula and left middle temporal gyrus(l-MTG)( x, y, z=-48, -39, 9, t=4.062, P<0.05), left supramarginal gyrus (x, y, z=-51, -15, 45, t=2.906, P<0.05), l-SFG (x, y, z=-24, -21, 39, t=3.044, P<0.05), l-IPL ( t=2.880, P<0.05) and r-IPL ( t=3.512, P<0.05) in rMDD group. (2) FC decreased in fMDD group between the habenula and right orbitofrontal cortex(r-OFC) ( t=-3.899, P<0.05) and l-MTG ( t=-4.023, P<0.05) than rMDD group, while FC increased between the habenula and left supramarginal gyrus ( t=4.157, P<0.05), l-SFG( t=3.327, P<0.05), left thalamus ( t=3.316, P<0.05) and l-IPL ( t=3.909, P<0.05) than rMDD group. (3)There was no significantly correlation between the HAMD 17 and the FC value changes among the different regions, and was marginal significantly correlation between duration of disease and the FC values from the habenula and l-MOG( r=0.328, P=0.063). Conclusion:Both fMDD and rMDD show abnormal FC between the habenula and default mode network, visual network and reward network, which may be related to the pathogenesis of depression. The FC of the habenula in rMDD still had not recovered to normal.

Tibial fracture is a kind of common long bone fracture of extremities, most of which are complex tibial fractures caused by high energy. Because of the special anatomical structure of tibia, the incidence of postoperative complications such as malunion and nonunion is higher. This brings some difficulties to the treatment. With the patient′s higher requirements for function, doctors have a deeper understanding of biomechanics, which promotes the further development of internal fixation materials. The indications of intramedullary nails have been expanded and gradually replaced the steel plate internal fixation for the treatment of tibial fractures and achieved good therapeutic effect. This article focuses on the application and new development of intramedullary nail in the treatment of proximal, middle, distal and open tibial fractures, providing more reference for the future clinical treatment.

Objective:To compare the clinical efficacy of femoral neck system (FNS) and cannulated screw fixation in the treatment of femoral neck fracture in the young and middle-aged patients.Methods:A retrospective cohort study was conducted to analyze the clinical data of 76 young and middle-aged patients with femoral neck fracture admitted to Honghui Hospital Affiliated to Xi′an Jiaotong University from March 2018 to September 2020, including 45 males and 31 females, aged 23-63 years [(49.5±8.2)years]. Garden classification of the fracture was 25 patients with type II, 34 with type III and 17 with type IV. Pauwels classification of the fracture was 16 patients with type I, 31 with type II and 29 with type III. A total of 40 patients were treated with cannulated screw fixation (cannulated screw group) and 36 patients with FNS fixation (FNS group). Operation time, frequency of fluoroscopy, length of hospital stay, weight-bearing time and bone union time were compared between the two groups. Hip function was assessed by Harris hip score at 6, 12 months after operation. The incidence of postoperative complications was observed.Results:All patients were followed up for 12-20 months [(15.2±1.7)months]. The frequency of fluoroscopy [(13.4±1.9)times], weight-bearing time [(11.1±1.9)weeks] and bone union time [(13.8±1.6)weeks] in FNS group were lower or shorter than those in cannulated screw group [(18.2±2.6)times, (15.7±1.6)weeks, (14.6±1.6)weeks] (all P<0.05 or 0.01). There were no significant differences in operation time, length of hospital stay and Harris hip score at 6, 12 months after operation between the two groups (all P>0.05). No postoperative infection occurred in both groups. In cannulated screw group, there were 4 patients with femoral neck shortening, 3 with deep venous thrombosis, 2 with internal fixation loosening, 2 with nail withdrawal and 1 with fracture non-union, showing the incidence of complications of 30% (12/40). In FNS group, there was 2 patients with femoral neck shortening, 1 with deep vein thrombosis and 1 with internal fixation loosening, showing the incidence of complications of 11% (4/36) ( P<0.05). Conclusion:For femoral neck fracture in the young and middle-aged patients, both FNS and cannulated screw fixation can obtain satisfactory efficacy, but FNS has the advantages of decreased frequency of intraoperative fluoroscopy, early weight bearing, reduced time to bone union and low incidence of complications.

Objective:To compare the clinical effects between cannulated screwing and plating in combination with interlocking intramedullary nailing for the treatment of ipsilateral discontinuous fractures of the tibial shaft and plateau.Methods:A retrospective analysis was performed of the clinical data of 34 patients who had been treated for ipsilateral discontinuous fractures of the tibial shaft and plateau at Department of Orthopedics and Trauma, Honghui Hospital Affiliated to Xi′an Jiaotong University from January 2015 to January 2020. There were 17 males and 17 females, aged from 26 to 60 years (average, of 43.6 years). The left side was affected in 18 cases and the right side in 16. The patients were divided into 2 groups according to their internal fixation methods: a cannulated screw group of 16 cases treated with cannulated screwing and intramedullary nailing and a plate group of 18 cases treated with plating and intramedullary nailing. The 2 groups were compared in terms of operation time, intraoperative blood loss, incision length, tibial plateau collapse, consumables cost, hospital stay, fracture healing time, weight-bearing time, range of knee motion, reduction of tibial plateau fracture by Rasmussen radiology, Lysholm knee function score at the last follow-up and complications.Results:There was no significant difference in the preoperative general data between the 2 groups, showing the 2 groups were comparable ( P>0.05). All the 34 patients were followed up for 12 to 28 months (average, 17.4 months). There was no significant difference either in operation time, hospital stay, tibial plateau healing time, tibial fracture healing time, weight-bearing time or range of knee motion between the 2 groups ( P>0.05). In the cannulated screw group, the intraoperative blood loss [(89.4 ± 14.5) mL] and consumables cost [(2.0 ± 0.2) ten thousand yuan] were significantly less than those in the plate group [(120.8 ± 22.1) mL and (2.6 ± 0.4) ten thousand yuan], the incision length [(4.1 ± 0.8) cm] was significantly shorter than that in the plate group [(7.1 ± 0.9) cm], and the Lysholm knee function score at the last follow-up [(89.8 ± 4.5) points] was significantly lower than that in the plate group [(93.0 ± 4.2 points] (all P<0.05). The difference was statistically significant between the 2 groups in the quality of tibial plateau reduction ( P<0.05). The postoperative tibial plateau collapse in the plate group [0.5 (0, 2) mm] was insignificantly less than that in the cannulated screw group [1.0 (0, 2) mm] ( P>0.05). In the cannulated screw group, one tibial shaft fracture did not achieve union after operation and deep vein thrombosis occurred in 2 cases after operation; in the plate group, 2 cases suffered from delayed wound healing, one from delayed fracture healing, one from deep venous thrombosis of lower extremity, and one from knee discomfort which was relieved after removal of internal fixation. Conclusions:In the treatment of ipsilateral discontinuous fractures of tibial shaft and plateau, both cannulated screwing and plating in combination with interlocking intramedullary nailing can achieve good clinical effects. Although plating in combination with intramedullary nailing lead to more severe trauma and higher costs, it is conducive to improving the reduction quality of the tibial plateau and postoperative functional recovery of the knee joint.

Objective:
To study the changes in the functional connections of the central executive network in patients with depression after clinical cure.
Methods:
Seventeen depression patients who met the clinical cure standard (patient group) and twenty-two healthy controls (control group) were selected.The baseline rs-fMRI data were collected from the healthy control group and the patient group respectively, and the rs-fMRI data in the patient group were collected again after 6 months.Compared the changes of central executive network function connection between the two groups.
Results:
At baseline, there was a high functional connection in the left inferior parietal lobule(MNI: x, y, z=-39, -69, 33)and right insula(MNI: x, y, z=15, -45, 30) in the patient group compared with the control group.Compared with the baseline, there were high functional connections in part of the left inferior parietal lobe (MNI: x, y, z=-60, -48, 21) and the right dorsolateral prefrontal lobe (MNI: x, y, z=24, 18, 60), and low functional connections in part of the left inferior parietal lobe (MNI: x, y, z=-51, -69, 18) in patient group 6 months after clinical cure.Compared with the control group, there was a high functional connection in the right dorsolateral prefrontal lobe (MNI: x, y, z=45, 51, -6) and the right inferior parietal lobe (MNI: x, y, z=42, -48, 27) in patient group 6 months after clinical cure.
Conclusion
The functional connection of central executive network of depression patients has not been restored, and the related abnormality is not stable in six months after reaching the clinical cure standard.
