Objective To elucidate the new concept and theory of neurorestoratology. Methods With the review of the development course and important research works in the field of neurorestoratology during the 20th century, especially recent 30 years, the regularity summary, science and technology philosophy induction, and theory distillation were carried out in this article. Results The new discipl ine system was brought forward as follows: ① Definition: neurorestoratology was asub-discipl ine of neuroscience which studies neural regeneration, neural structural repair of replacement, eruroplasticity and neuromodulation. The core purpose was to promote neural functional recovery of all neural degenerative diseases and damages. ② One central task and two basic points: to recover neurological function was the central research task all the time and the two basic points were the precl inical (basic) neurorestoration and the cl inical neurorestoration. ③ Four rationale of the discipl ine: l imited renovation, relearning, insufficient reserve, and l ifelong reinforcement. ④ Five major factors of neurorestoratology (5N’s dogma): neuroregeneration, neurorepair, neuroplasticity, neuromodulation, neurorehabil itation. “Neuroprotection” appeared to be included in the broad definition. ⑤ Four-step rule of neurorestoratology: structural neurorestoration, signal neurorestoration, rehabil itative neurorestoration, and functional neurorestoration. ⑥ Emphasize that translational medicine from lab to bed in neurorestoration. Conclusion The discipl ine of neurorestoratology has the vast development prospectand will be sure to increase the rapid progress of the basic and cl inical restorative neuroscience.
Previous studies have shown that growth arrest, dedifferentiation, and loss of original function occur in cells after multiple generations of culture, which are attributed to the lack of stress stimulation. To investigate the effects of multi-modal biomimetic stress (MMBS) on the biological function of human bladder smooth muscle cells (HBSMCs), a MMBS culture system was established to simulate the stress environment suffered by the bladder, and HBSMCs were loaded with different biomimetic stress for 24 h. Then, cell growth, proliferation and functional differentiation were detected. The results showed that MMBS promoted the growth and proliferation of HBSMCs, and 80 cm H2O pressure with 4% stretch stress were the most effective in promoting the growth and proliferation of HBSMCs and the expression level of α-smooth muscle actin and smooth muscle protein 22-α. These results suggest that the MMBS culture system will be beneficial in regulating the growth and functional differentiation of HBSMCs in the construction of tissue engineered bladder.
With chronic kidney disease becoming a public health problem in the world, dialysis treatment model has also become the focus of attention from all walks of life. Sustained low-efficiency dialysis, which adopts the mode of low blood flow and low dialysis volume, is a kind of hybrid renal replacement therapy combining continuous renal replacement therapy and intermittent hemodialysis. It has unique advantages in the treatment of patients with acute and severe renal injury, as well as the dialysis duration, patient activity range and cost. It is the most widely used hybrid renal replacement therapy too. This review summarizes the clinical application and nursing points of sustained low-efficiency dialysis to provide guidance for clinical practice.

ObjectiveTo explore the application of different digestive system management strategies in the perioperative period of thoracolumbar fracture.MethodsThe clinical data of the patients with thoracolumbar fractures and pedicle screw fixation in Affiliated Hospital of Southwest Medical University from January 2016 to January 2018 were retrospectively analyzed. According to different perioperative management strategies of the digestive system, they were divided into two groups. Patients with careful management strategy were included in the observation group, and patients with routine management were included in the control group. The baseline conditions, the abnormalities of digestive tract function at admission and before and after surgery, the postoperative first feeding time, exhaust time, defecation time, the incidence of other postoperative complications except digestive tract complication, length of stay and patient satisfaction were compared between the two groups. At 6 months after surgery, the fracture healing, loosening or fracture of internal plants were compared between the two groups.ResultA total of 121 patients were included in the study, including 67 cases in the observation group and 54 cases in the control group. There was no significant differences in the baseline conditions between the two groups (P>0.05). There were no significant differences between the two groups in the incidences of digestive system dysfunction at admission (P>0.05). The incidences of digestive system dysfunction in the observation group before and after surgery were lower than those in the control group (29.9% vs. 53.7%, P<0.05; 35.8% vs. 61.1%, P<0.05). The first eating time [(3.7±1.1) vs. (6.7±2.6) h], exhaust time [(7.8±2.3) vs. (13.6±4.2) h], defecation time [(26.7±8.1) vs. (40.9±11.2) h] and length of stay [(6.5±2.4) vs. (9.0±2.7) d] in the observation group were shorter than those in the control group (P<0.005), and the patients’ satisfaction was better than that of the control group (8.3±1.1 vs. 7.6±1.3; t=−3.208, P=0.002). There was no statistically significant difference in the incidence of postoperative complications except digestive tract complication, and the fracture healing rate, the incidence of nail-rod breakage at6 months after surgery between the two groups (P>0.05). No internal plant loosening was found in the two groups of patients within 6 months after surgery.ConclusionThe application of the careful digestive system management strategy in patients with thoracolumbar fractures can help reduce the incidence of perioperative gastrointestinal dysfunction, promote the recovery of perioperative gastrointestinal function, shorten the length of hospital stay, and improve patient satisfaction.

OBJECTIVE: To study the morphological character of long head of triceps muscle for clinical application in reconstruction of shoulder abduction. METHODS: Forty-four upper extremities of fixed human adult cadavers were carefully dissected. The origins and the pedicles of blood vessels and nerves of long head of triceps muscle, as well as the maximum available size of the muscles, were measured. Six cases of clinical application of long head of triceps muscle for reconstruction of shoulder abduction were followed up for 3 to 11 months. RESULTS: The origins in the dorsal side of long head of triceps muscle were muscular and the ventral side were tendinous, which was 7.6 to 13.3 cm in length and 1.6 to 3.4 cm in width. The distance from the origin to the neurovascular pedicle was 5.7 to 11.4 cm. The radial nerve, which innervated the muscles, could be dissected for 2.9 to 11.8 cm in length. The blood supplies to the triceps muscle were from humeral artery (43.2%), 1.0 to 6.0 cm in length and 1.6 to 2.4 mm in diameter, and from humeral profundus artery (45.5%), 1.5 to 4.4 cm in length and 0.9 to 2.4 mm in diameter, if the vessel was separated to the humeral artery, the length was 1.5 to 6.3 cm. The neurovascular pedicles were multiple branched. In the 6 cases of clinical application of the triceps muscles, the operated shoulder could abduct from 5 degrees preoperatively (0 degree to 10 degrees) to 77.3 degrees (50 degrees to 90 degrees) postoperatively. CONCLUSION: In accordance to the anatomical character of the triceps muscles, the long head of triceps muscle is a suitable choice for reconstruction of shoulder abduction with optimistic outcomes.
Objective To define a safe distance range from the LC-Ⅱ screw trajectory to the apex of the greater sciatic notch based on pelvic CT measurements, and to clinically assess the feasibility of using this range under iliac oblique view combined with iliac tangential view fluoroscopy to guide screw insertion. Methods CT scans of 104 normal pelvises collected between January 2022 and February 2025 were analyzed. There were 52 males and 52 females, with a median age of 45.8 years (range, 19-76 years). The RadiAnt DICOM Viewer software was used to reconstruct coronal, sagittal, and axial sections of the potential LC-Ⅱ screw trajectory. The maximum safety distance (Dmax) and the optimal safety distance (Dopt) from this trajectory to the greater sciatic notch were measured on the coronal and sagittal views. A retrospective analysis was conducted on 21 patients with LC-Ⅱ type pelvic fractures treated with the LC-Ⅱ screws fixation. And the screws were placed within the pre-defined safe distance under guidance from the iliac oblique view and iliac tangential view. Postoperative CT scans were obtained to evaluate the accuracy of screw placement. Results Radiographic measurements from the 104 cases showed that Dmax ranged from 1.87 to 3.87 cm (mean, 2.79 cm), and Dopt ranged from 1.01 to 2.92 cm (mean, 1.84 cm). Both Dmax and Dopt were significantly greater in the males than in the females (P>0.05). No significant difference was found between the left and right sides within the same gender (P>0.05). All 21 patients successfully underwent fracture reduction and fixation, with a total of 23 LC-Ⅱscrews implanted. According to the Lonstein grading system, the screw placement accuracy was rated as excellent in 16 screws, good in 3, fair in 3, and poor in 1, with an excellent and good rate of 82.6%. ConclusionUtilizing a CT-defined safe distance range from the screw trajectory to the greater sciatic notch, and adhering to this range under iliac oblique view combined with iliac tangential view fluoroscopy, enables the accurate and precise placement of LC-Ⅱ screws.
