Post traumatic depression (PTD) is a serious complication after traumatic brain injury, with high incidence rate; PTD seriously affects the rehabilitation, outcome and quality of life of patients. Due to unclear pathogenesis of PTD, effective treatments have not yet been found in clinical practice. Repetitive transcranial magnetic stimulation (rTMS), as a new non-invasive neuroregulatory technique, has been used in major depression disorder (MDD). Few clinical evidence on PTD treated by rTMS is noted and optimal rTMS treatment regimen has not yet been defined.This article reviews the clinical studies of rTMS in PTD in recent years, with a view to provide references for clinical application.

Objective:To evaluate the impact of bladder volume on dosimetric parameters of clinical target volume (CTV) and organs at risk (OAR) of intensity modulated proton therapy (IMPT) for localized prostate cancer during the treatment planning and daily treatment.Methods:Clinical data of 25 patients with localized prostate cancer admitted to Ruijin Hospital affiliated to Shanghai Jiao Tong University School of Medicine from November 2021 to June 2022 and enrolled in the "Proton Therapy System" (SAPT-PS-01) registered clinical trial were retrospectively analyzed. All patients were male and the median age was 72 years old. A total of 30 sets of IMPT plans were obtained. Based on the planning CT (30 sets) and weekly verification CT during treatment (172 sets), bladder volume, CTV and OAR dose parameters were collected. Spearman correlation analysis was used to evaluate the correlation between bladder volume in CT and the dosimetric parameters of CTV and OAR during IMPT plans, and Wilcoxon-Mann-Whitney test was adopted to compare the dosimetric parameters of CTV and OAR among different bladder volume change groups.Results:The V 95% of CTV1 and CTV2 were both 100.0%±0.0% in IMPT plans. Bladder volume was significantly negatively correlated with D mean, V 70 Gy(RBE), V 60 Gy(RBE), V 50 Gy(RBE), V 40 Gy(RBE) of the bladder ( P<0.001, 0.003, <0.001, <0.001,<0.001), and D mean, V 50 Gy(RBE) of the small intestine (both P<0.001). During treatment, bladder D mean, V 70 Gy(RBE), V 60 Gy(RBE), V 50 Gy(RBE), V 40 Gy(RBE)( P<0.001, 0.001, <0.001, <0.001, <0.001), rectal D mean, V 50 Gy(RBE), V 40 Gy(RBE) (all P<0.001), small intestine D mean, V 50 Gy (RBE) (both P<0.001) of patients with bladder volume increase >20% compared to baseline were significantly decreased compared to those in IMPT plans. But CTV1 V 100%, and CTV2 V 95% were significantly decreased too( P=0.029, 0.020). In the bladder volume decreased>20% patients, the D mean, V 70 Gy(RBE), V 60 Gy(RBE), V 50 Gy(RBE), V 40 Gy(RBE) of the bladder were significantly increased compared to those in IMPT plans (all P<0.001). However, a bladder volume reduction of ≤20% and increase of ≤20% from baseline had no significant impact on CTV and OAR dosimetric parameters during treatment. Conclusions:For patients with localized prostate cancer undergoing proton therapy, a certain bladder volume should be ensured during planning CT scans. During the daily treatment, the bladder volume should be maintained between 80%-120% of the baseline level to ensure CTV coverage and good dose sparing to OAR.

Objective To investigate the effect of salidroside on intestinal mucosal immune status in rats under compound stress of hypoxia and training (HTCS) and the mechanism. Methods SD rats were randomly divided into HTCS model group (model), placebo group (placebo) and salidroside group (salidro). Model group received no intervention, and placebo and salidro group received intraperitoneal injection of normal saline and salidroside, respectively. Then, ileum tissue of rats were collected and the intestinal damage was assayed by HE staining and Chiu scores. Intestinal permeability indices, including serum D-diamine oxidase (DAO), D-lactic acid (DLA) and endotoxin (END) and secretory immunoglobulin A (sIgA) of intestinal tissue were detected by ELISA. T lymphocyte subsets of intestinal tissue were detected by flow cytometry. Expression of tight junction molecules, including ZO-1, Claudin-3, occluding, were detected by PCR and western blot. Activation of TLR4/NF-κB signaling pathway was detected by Western blot analysis. Results Compared with model group and placebo group, salidro group had the decreased intestinal mucosal injury and low Chiu score, and the level of intestinal permeability indices including serum DAO, DLA and END fell off. CD4+ T cell percentage, CD4+/CD8+ ratio and sIgA level were went up, while CD8+ T cell percentage was went down. mRNA and the level of protein expressions of ZO-1, claudin-3 and occludin increased, while activation of TLR4/NF-κB signaling pathway was inhibited. Conclusion Salidroside can alleviate the intestinal barrier injury and improve intestinal mucosal immune status of rats under compound stress of hypoxia and training via inhibiting TLR4/NF-κB signalling pathway.

Objective To investigate the efficacy and safety of lenvatinib combined with sintilimab as the second-line therapy for advanced intrahepatic cholangiocarcinoma (ICC). Methods A retrospective analysis was performed for the clinical data of the patients with advanced ICC who were admitted to Beijing Ditan Hospital from October 31, 2019 to October 31, 2021 and could not undergo surgery or experienced metastasis after surgery. All patients were treated with lenvatinib combined with sintilimab as the second-line therapy. The patients were followed up, and the RECIST1.1 criteria were used to assess treatment outcome. The primary endpoint was time to progression (TTP), and the secondary endpoints were tumor objective response rate (ORR), disease control rate (DCR), overall survival (OS) time, and safety. The Kaplan-Meier method was used to plot survival curves, and the log-rank test was used for comparison between groups. Results A total of 27 patients were enrolled, among whom there were15 male patients (55.6%) and 12 female patients (44.4%), with a median age of 58 years (range 33-73 years). The median TTP for these patients was 5.5 (95% confidence interval [ CI ]: 1.7-9.3) months, and 13 patients (48.1%) died of disease progression, with a median OS time of 11.2 (95% CI : 5.0-17.4) months. The overall ORR and DCR were 40.7% and 70.3%, respectively. Of all patients, 66.7% experienced varying degrees of adverse events, and among these patients, 44.4% had an increase in alanine aminotransferase, 44.4% had an increase in aspartate aminotransferase, 37.0% had hypertension, 29.6% had an increase in bilirubin, 29.6% experienced diarrhea, and 25.9% each experienced proteinuria, anorexia, and weakness. No treatment-related death was observed, and only 1 patient developed grade Ⅳ immune-related hepatotoxicity and was relieved without sequelae after corticosteroid therapy, resulting in permanent withdrawal of sintilimab. The patients with lymph node metastasis had a significantly shorter median TTP than those without lymph node metastasis (4.5 months vs 18.8 months, P =0.035), and the patients who achieved disease remission had a significantly longer median TTP [11.6 months (95% CI : 5.6-17.6) vs 2.8 months (95% CI : 1.8-3.8), P < 0.001]; the patients with lymph node metastasis had a shorter median OS time [9.6 months (95% CI: 7.9-11.3) vs 21.9 months (95% CI : 0-44.9), P =0.053], and the patients who achieved disease remission had a significantly longer median OS time [16.6 months (95% CI : 9.0-24.2) vs 6.9 months (95% CI : 3.6-10.2), P =0.011]. Conclusion Lenvatinib combined with sintilimab has a marked clinical effect and a low incidence rate of serious adverse events as the second-line therapy for advanced ICC, and therefore, it is a safe and effective treatment regimen.

Objective:To investigate the effect of arthroscopically-assisted open reduction and internal fixation of intra-articular distal radius fracture.Methods:A retrospective cohort study was made on clinical data of 44 patients with distal radial intraarticular fracture admitted to Jing′an District Central Hospital, Fudan University between June 2017 and August 2020. There were 13 males and 31 females, at age of 35-85years [(62.5±12.9)years]. According to AO/OTA fracture classification system, there were 7 patients with type B and 37 with type C. Open reduction and internal fixation with volar plate was used in all patients, among which 22 were operated on using arthroscopy assistance (arthroscopy group) and 22 were operated on with traditional intraoperative fluoroscopy (fluoroscopy group). The operation time in both groups and triangular fibrocartilage complex (TFCC) injury and fracture displacement in arthroscopy group were recorded. Patient-rated wrist evaluation (PRWE) score, disabilities of the arm, shoulder and hand (DASH) questionnaire and range of wrist motion were compared between the two groups at 12 months after operation. The incidence of complications was observed.Results:All patients were followed up for 12-15 months [(13.3±1.1)months]. The operation time in arthroscopy group was (104.0±40.5)minutes, longer than (71.3±32.1)minutes in fluoroscopy group ( P<0.05). In arthroscopy group, 14 patients (64%) with TFCC injury were diagnosed intraoperatively, with the fracture displacement gap and step for 0.8 (0.3, 0.8)mm and 1.0 (0.3, 1.5)mm under arthroscopic vision, which were reduced to 0.3 (0.0, 0.5)mm and 0.5 (0.0, 0.5)mm after arthroscopically-assisted reduction (all P<0.05). The PRWE score in arthroscopy group was (9.8±4.9)points at 12 months after operation, lower than (13.4±5.8)points in fluoroscopy group ( P<0.05). The DASH questionnaire in arthroscopy group was (9.0±5.0)points at 12 months after operation, lower than (13.0±6.1)points in fluoroscopy group ( P<0.05). The dorsal extension and posterior rotation of the wrist in arthroscopy group were (73.8±8.9)° and (82.5±8.0)°, higher than (65.8±14.2)° and (76.3±10.4)° in fluoroscopy group (all P<0.05). There were no postoperative complications such as loosened or broken screws, vascular nerve damage, incision infection or traumatic arthritis in both groups. Conclusion:Arthroscopic-assisted open reduction and internal fixation of intra-articular distal radius fracture can increase the accuracy of joint surface reduction, improve postoperative wrist function and confirm the diagnosis of TFCC injury during operation.

Central nervous system (CNS) injuries, including stroke, traumatic brain injury, and spinal cord injury, are leading causes of long-term disability. It is estimated that more than half of the survivors of severe unilateral injury are unable to use the denervated limb. Previous studies have focused on neuroprotective interventions in the affected hemisphere to limit brain lesions and neurorepair measures to promote recovery. However, the ability to increase plasticity in the injured brain is restricted and difficult to improve. Therefore, over several decades, researchers have been prompted to enhance the compensation by the unaffected hemisphere. Animal experiments have revealed that regrowth of ipsilateral descending fibers from the unaffected hemisphere to denervated motor neurons plays a significant role in the restoration of motor function. In addition, several clinical treatments have been designed to restore ipsilateral motor control, including brain stimulation, nerve transfer surgery, and brain-computer interface systems. Here, we comprehensively review the neural mechanisms as well as translational applications of ipsilateral motor control upon rehabilitation after CNS injuries.

Our previous investigation suggested that faster seventh cervical nerve (C7) regeneration occurs in patients with cerebral injury undergoing contralateral C7 transfer. This finding needed further verification, and the mechanism remained largely unknown. Here, Tinel’s test revealed faster C7 regeneration in patients with cerebral injury, which was further confirmed in mice by electrophysiological recordings and histological analysis. Furthermore, we identified an altered systemic inflammatory response that led to the transformation of macrophage polarization as a mechanism underlying the increased nerve regeneration in patients with cerebral injury. In mice, we showed that, as a contributing factor, serum amyloid protein A1 (SAA1) promoted C7 regeneration and interfered with macrophage polarization in vivo. Our results indicate that altered inflammation promotes the regenerative capacity of the C7 nerve by altering macrophage behavior. SAA1 may be a therapeutic target to improve the recovery of injured peripheral nerves.

Objective:To investigate the protective effects of Elabela(ELA) on the renal injury of db/db mice and its possible mechanism.Methods:Sixteen eight-week-old male db/db mice were intraperitoneally injected with ELA(5 mg·kg -1·day -1) or equivalent normal saline( n=8) for 8 weeks. Eight age-matched male db/m mice received equivalent normal saline injection as normal control. At the end of the experiment, blood and urine samples were obtained for HbA 1C and urinary albumin/creatinine(ACR) measurements. Immunohistochemistry was used to observe the expression of ELA. Histopathological changes in kidney tissue were observed by HE staining and Masson staining. The levels of collagen type Ⅳ(Col-Ⅳ) and transforming growth factor-β1(TGF-β1) as well as Yes-associated protein(YAP) phosphorylation in kidney tissue were examined by western blot. Results:Immunohistochemistry results showed that ELA expression was decreased in the renal tissue of db/db mice as compared with that of db/m mice( P<0.05). After ELA treatment, ACR and blood pressure were markedly decreased in db/db mice( P<0.05), but without significant changes in the body weight and HbA 1C. Renal tubular epithelial cells edema, basement membrane thickening, and increased collagen fiber in db/db were improved by ELA administration. Compared with db/m mice, the levels of TGF-β1 and Col-Ⅳ expression, as well as YAP phosphorylation were significantly increased in renal tissue of db/db mice(0.98±0.08 vs 0.68±0.10, 1.10±0.14 vs 0.51±0.08, 3.38±0.72 vs 0.81±0.13, all P<0.05), which were down-regulated after ELA administration(0.80±0.06, 0.51±0.05, 2.21±0.22, all P<0.05). Conclusion:ELA may improve the renal injury of db/db mice by regulating the signaling pathway of YAP, thereby delaying the development of diabetic nephropathy.
