OBJECTIVE: To explore effectiveness of TiRobot-assisted screw implantation in the treatment of coracoid process fractures of the scapula. METHODS: A retrospective analysis was conducted on the clinical data from 24 patients with coracoid process fractures of the scapula admitted between September 2019 and January 2024 and met selection criteria. Among them, 12 patients underwent TiRobot-assisted screw implantation (robot group) and 12 underwent manual screw implantation (control group) during internal fixation. There was no significant difference ( P>0.05) in baseline data such as gender, age, body mass index, disease duration, cause of injury, coracoid process fracture classification, and proportion of patients with associated injuries between the two groups. The incision length, operation time, intraoperative blood loss, hospital stay, accuracy of screw placement, coracoid process fracture healing time, and complications were recorded and compared, as well as pain visual analogue scale (VAS) score, and Constant-Murley score at last follow-up. RESULTS: The intraoperative blood loss and incision length in the robot group were significantly lower than those in the control group ( P<0.05); however, there was no significant difference in operation time and hospital stay between the two groups ( P>0.05). All patients were followed up 8-27 months (mean, 17.5 months), and the difference in follow-up time between the two groups was not significant ( P>0.05). At last follow-up, the VAS score for shoulder pain in the robot group was signifncatly lower compared to the control group, and the Constant-Murley score was significantly higher ( P<0.05). In the robot group, 16 screws were implanted intraoperatively, while 13 screws were implanted in the control group. Radiographic re-evaluation showed that the excellent and good rate of screw implantation was higher in the robot group (93.8%, 15/16) than in the control group (61.5%, 8/13), but the difference in the precision of screw implantation between the two groups was not significant ( P>0.05). Four patients in the robot group and 1 in the control group achieved double screws fixation; however, the difference in achieving double screws fixation between the two groups was not significant ( P>0.05). All fractures healed in both groups with 1 case of malunion in the control group. There was no significant difference in healing time between the two groups ( P>0.05). During follow-up, 1 patient in the control group experienced screw loosening and displacement. There was no significant difference in the incidence of screw loosening and fracture malunion between the two groups ( P>0.05). CONCLUSION Compared with manual screw implantation, TiRobot-assisted minimally invasive treatment of coracoid process fractures of the scapula can reduce intraoperative blood loss, shorten incision length, alleviate pain, and obtain better promote shoulder joint functional recovery.

OBJECTIVE: To investigate the effectiveness of TiRobot-assisted minimally invasive treatment for fragility fractures of the pelvis (FFP) in elderly patients. METHODS: A retrospective analysis was conducted on the clinical data of 176 patients with FFP who were admitted between July 2018 and July 2024 and met the selection criteria. Among them, 95 patients underwent TiRobot-assisted closed reduction and minimally invasive cannulated screw fixation (robot group), while 81 patients underwent traditional open reduction and plate screw fixation (control group). There was no significant difference in baseline data such as gender, age, fracture classification, disease duration, and preoperative visual analogue scale (VAS) pain scores between the two groups ( P>0.05). The following parameters were recorded and compared between the two groups, including operation time, intraoperative blood loss, intraoperative transfusion rate, volume of intraoperative blood transfusion, maximum incision length, hospital stay, maximum residual displacement, reduction quality, fracture healing time, incidence of complications, VAS scores, Majeed pelvic function scores, and functional grading. RESULTS: All surgeries in both groups successfully completed. The robot group exhibited significantly shorter operation time, reduced intraoperative blood loss, lower intraoperative transfusion rate, smaller volume of intraoperative blood transfusion, shorter maximum incision length, and shorter hospital stay compared to the control group ( P<0.05). In the robot group, a total of 14 INFIX internal fixation frames and 280 cannulated screws were implanted, among which 250 screws were rated as excellent, 17 as good, and 13 as poor, resulting in a screw placement excellent and good rate of 95.36%. Radiological review revealed that the excellent and good rate of reduction quality was in 91.58% (87/95) in the robot group and 81.48% (66/81) in the control group, with no significant difference in postoperative maximum residual fracture displacement or reduction quality between the two groups (P>0.05). All patients in both groups were followed up 12-66 months, with an average of 28.9 months, and there was no significant difference in follow-up time between the two groups ( P>0.05). The fracture healing time in the robot group was significantly shorter than that in the control group ( P<0.05). At last follow-up, both groups showed significant improvement in VAS scores compared to preoperative values ( P<0.05); the change values of VAS scores, Majeed scores, and the excellent and good rate of Majeed pelvic function were significantly higher in the robot group than in the control group ( P<0.05). Regarding postoperative complications, there was no significant difference between the two groups in terms of gait changes, secondary surgeries, heterotopic ossification, incision infections, walking difficulties, internal fixation failure, or mortality rates ( P>0.05); however, the incidence of delayed wound healing was significantly lower in the robot group than in the control group ( P<0.05). CONCLUSION TiRobot-assisted minimally invasive treatment of elderly FFP is superior to traditional open reduction and internal fixation in terms of surgical trauma control, postoperative rehabilitation speed, and functional recovery.

PURPOSE: Traumatic brain injury (TBI) is a significant public health issue that impacts individuals all over the world and is one of the main causes of mortality and morbidity. Decompressive craniectomy is the usual course of treatment. Basal cisternostomy has been shown to be highly effective as an alternative procedure to decompressive craniectomy. METHODS: We conducted a retrospective cohort of patients who received surgery for severe TBI between January 2019 and March 2023. Inclusion criterias were patients between the ages of 18 and 70 years who met the diagnostic criteria for severe TBI at first presentation and who underwent surgical intervention. The exclusion criteria were patients who have severe multiple injuries at the time of admission; preoperative intracranial pressure > 60 mmHg; cognitive impairment before the onset of the disease; hematologic disorders; or impaired functioning of the heart, liver, kidneys, or other visceral organs. Depending on the surgical approach, the patients were categorized into decompressive craniectomy group as well as basal cisternostomy group. General data and postoperative indicators, including Glasgow coma scale, intracranial pressure, etc., were recorded for both groups of patients. Among them, the Glasgow outcome scale extended assessment at 6 months served as the primary outcome. After that, the data were statistically analyzed using SPSS software. RESULTS: The trial enrolled 41 patients (32 men and 9 women) who met the inclusion criteria. Among them, 25 patients received decompressive decompressive craniectomy, and 16 patients received basal cisternostomy. Three days postoperative intracranial pressure levels were 10.07 ± 2.94 mmHg and 17.15 ± 14.65 mmHg (p = 0.013), respectively. The 6 months following discharge Glasgow outcome scale extended of patients was 4.73 ± 2.28 and 3.14 ± 2.15 (p = 0.027), respectively. CONCLUSION Our study reveals that basal cisternostomy in patients with surgically treated severe TBI has demonstrated significant efficacy in reducing intracranial pressure as well as patient prognosis follow-up and avoids removal of the bone flap. The efficacy of cisternostomy has to be studied in larger, multi-clinical center randomized trials.

OBJECTIVES: To explore the efficacy of low-intensity pulsed ultrasound (LIPUS) combined with nystatin for treatment of vaginal Candida albicans biofilm infection. METHODS: In vitro cultured Candida albicans biofilm were treated with LIPUS, nystatin, or both, and the minimum inhibitory concentration (MIC) of nystatin was determined. Crystal violet staining, confocal laser microscopy (CLSM) and scanning electron microscopy were used to quantify the biofilm and observe the activity and morphological changes of the biofilms; DCFH-DA was used to detect the changes in reactive oxygen species (ROS). Twenty female New Zealand White rabbits with vaginal inoculation of Candida albicans biofilm were randomized into 4 groups for treatment with normal saline, LIPUS, nystatin, or both LIPUS and nystatin. The changes in vulvar symptoms of the rabbits were observed, and the histopathological and ultrastructural changes of the vagina before and after treatment were observed using HE staining and transmission electron microscopy. RESULTS: In the combined treatment group, the MIC₅₀ and MIC₈₀ of nystatin in Candida albicans biofilms were both reduced by 50% compared with those in nystatin group, and the biofilm clearance rate increased by 26% and 68% compared with nystatin and LIPUS groups, respectively. Compared with nystatin and LIPUS treatment alone, the combined treatment produced stronger effects for inhibiting biofilm activity, causing structural disruption and promoting ROS production. In the rabbit models, the combined treatment more effectively improved vulvar symptoms and inflammatory infiltration, reduced residual vaginal hyphae/strains, and improved ultrastructure of the vaginal epithelium than LIPUS and nystatin treatment alone. CONCLUSIONS LIPUS combined with nystatin produces a significant synergistic antifungal effect against Candida albicans biofilm both in vitro and in vivo.

This study identified six novel azaphilones, isochromophilones G-L (1-6), and three novel biosynthetically related congeners (7-9) from Diaporthe sp. SCSIO 41011. The structures and absolute configurations were elucidated through comprehensive spectroscopic analyses combined with experimental and calculated electronic circular dichroism (ECD) spectra. Significantly, three highly oxygenated azaphilones contain an acetyl group at the terminal chain (4) or linear conjugated polyenoid moieties (5 and 6), which occur infrequently in the azaphilone family. Additionally, several compounds demonstrated inhibition of lipopolysaccharide (LPS)-induced nuclear factor kappa-B (NF-κB) activation in RAW 264.7 macrophages at 20 μmol·L^-1. The novel compound (1) effectively inhibited receptor activator of NF-κB ligand (RANKL)-induced osteoclast differentiation without exhibiting cytotoxicity in bone marrow and RAW 264.7 macrophages, indicating its potential as a promising lead compound for osteolytic disease treatment. This research presents the first documented evidence of azaphilone derivatives as inhibitors of RANKL-induced osteoclastogenesis.

Objective:To explore the associations of temperature, relative humidity, and their interaction effect with fall risk.Methods:Data on fall cases were collected using the national injury surveillance system from May to September, in 2006-2022 in Hubei Province. Combined with the meteorological and air pollution data, we conducted a time-stratified case-crossover design and used conditional logistic regression models and distributed lag nonlinear models to examine the exposure-response relationships between temperature, humidity, and fall risk. We further divided the low and the high temperature groups and the low and the high relative humidity groups and analyzed the excess risk ( ER) of falls attributed to dry-hot or wet-hot events. Finally, we calculated the additive interactions of temperature and humidity on fall risk. Results:A total of 55 401 fall cases were included. With the increase in temperature and relative humidity decrease, the exposure-response curves of fall showed nonlinear upward trends among all populations. Gender and age differences were found in temperature-fall and relative humidity-fall risk relationships. Compared with wet-non-hot (normal temperature and high relative humidity) events, the ER of fall in dry-hot (high temperature and low relative humidity) events was 14.80% (95% CI: 9.69%- 20.15%), and the ER of wet-hot (high temperature and high relative humidity) events was 9.59% (95% CI: 2.52%-17.13%). However, there was no statistically significant difference between dry-hot and wet-hot events in the fall, and no statistically significant difference between different genders, ages, occupations, and fall occurred place (all P>0.05). No significant synergistic additive interaction was found between temperature and relative humidity on fall risk (relative excess risk due to interaction=-0.08, 95% CI: -0.19-0.02). Conclusions:Higher temperatures and lower relative humidity were associated with increased fall risk. Both dry-hot and wet-hot events had a higher risk of fall, while high temperature and low humidity have no synergistic effect on fall risk.

Objective:To investigate the clinical features, pathologic characteristics, treatment and prognosis of primary mediastinal large B-cell lymphoma (PMBCL) in children.Methods:Clinical data including clinical manifestations, treatment, clinical efficacy of 8 cases of childhood PMBCL treated in Beijing Children′s Hospital, Capital Medical University from March 2017 to February 2024 were collected retrospectively, the clinical characteristics and prognosis of them were summarized.Results:Among the 8 children, there were 5 males and 3 females. The age at the time of initial diagnosis was 11.0 (10.3, 13.5) years. The first clinical symptoms were cough (8 cases) and stridor (6 cases). The lesions most often involved the mediastinum (8 cases), lungs (5 cases, hilum more often), pericardium (5 cases), and pleura (4 cases). Extra thoracic invasion was present in 4 cases, 7 cases had huge tumor lesions and 7 cases were phase Ⅲ clinical stage. Except for 1 case who underwent surgical resection of the tumor, the remaining 7 cases were treated with DA-EPOCH+R (dose adjusted-etoposide+prednisone+vincristine+cyclo-phosphamide+doxorubicin+rituximab) chemotherapy. The follow-up time was 25.0 (10.5, 43.3) months, with 7 cases in complete and partial metabolism response, 1 case had disease progression. All 8 cases survived.Conclusions:PMBCL is most common in school-age boys and most of them present with huge mediastinal tumor focus. PMBCL expresses B-cell spectrum antigens and weakly expresses CD30.The application of DA-EPOCH+R is effective in the treatment of PMBCL in children.
