Objective To investigate the effect of exercise on the recovery of locomotor and neurological function in rats after incomplete spinal cord injury (SCI). Methods Ninety-five male Sprague Dawley rats were randomly divided into a control group, a training group (including subgroups which received training for 1 week, 2 weeks, 3 weeks and 4 weeks) and a sham operation group. The control and training groups were administered an SCI model at the T_(10) level by extradural compression using a modified Allen's stall with a damage energy of 40 g-cm. These rats were loosely restrained and given partial weight-bearing treadmill training 5min/time, twice a day for 1-4 weeks. Locomotor and neurological function were evaluated with inclined plane tests, modified Tarlov scores, the Basso-Beattie-Bresnahan scale and spinal cord somatosensory evoked potential (SCSEP) before injury and at different time points thereafter. Results Locomotor function improved significantly at different time points during the train-ing, and significantly better than in the control group. In the rats trained for 2-4 weeks, SCSEP latency shortened sig-nificantly compared to the control group. The latency shortened gradually with longer exercise. Conclusions Exer-cise with partial weight support may improve locomotor and neurological function. The improvements are correlated closely with the duration of the training.

Objective:To investigate the current situation of perioperative fasting management in patients with orthopaedic trauma waiting for elective surgery (those combined with diabetes mellitus included) and the surgeons' awareness in China.Methods:From November 1st to December 31st, 2021, the questionnaire forms were distributed through WeChat in the exchange group of National Enhanced Recovery Surgery (ERAS) and the exchange group of national training orthopaedists in Beijing Jishuitan Hospital. The survey contents included: time for preoperative water deprivation and for postoperative recovery of drinking in patients without diabetes mellitus, the rationales for orthopaedists to choose perioperative dietary management, the orthopaedists'understanding of the existing guidelines, time for preoperative water deprivation and postoperative recovery of drinking and diabetes-related issues in patients with diabetes mellitus, and the time for postoperative recovery in all the patients (For the postoperative recovery of eating, there is no difference between patients with and without diabetes mellitus). The relationships were analyzed between some professional data of the orthopaedists and their rationales for choice of management strategies and their understanding of the guidelines.Results:A total of 565 valid questionnaires were collected. 12.92% (73/565) of orthopaedists required their patients without diabetes mellitus not to drink for at least 2 hours. In fact, the proportion of water prohibition from 0 o'clock on the day of operation was still the highest [24.07% (136/565)]. Respectively, 22.83% (129/565) and 42.12% (238/565) of the orthopaedists chose "water intake is allowed once awakened" and "water intake after at least 6 hours after operation" for their patients without diabetes mellitus. 33.98% (192/565) of the orthopaedists required all the patients fasted for at least 6 hours before surgery, and 44.25% (250/565) of the orthopaedists chose "eating can be resumed if there is no discomfort for 2 hours after water intake" .21.06% (119/565) of the orthopaedists demonstrated that they were quite familiar with the guidelines and carried out perioperative dietary management according to the guidelines. The management of water deprivation was more inconsistent for patients with diabetes mellitus, and more hospitals followed the traditional principles for water deprivation. The proportions of water deprivation starting at 0 o'clock on the day of operation, 8 hours before operation, 6 hours before operation and 4 hours before operation accounted respectively for 22.83% (129/565), 19.12% (108/565), 21.95% (124/565), and 18.94%% (107/565). The level of an orthopaedist's hospital and the professional rank of an orthopaedist were the factors related to the orthopaedist's understanding of the guidelines ( P<0.05). Conclusions:The current perioperative dietary management guidelines are not widely implemented or well known in Chinese faculties of orthopaedic trauma. The process of perioperative dietary management needs to be optimized for the patients combined with diabetes mellitus.

Objective:To observe the therapeutic effect of microwave ablation combined with anhydrous ethanol for cystic thyroid nodules.Methods:From Jan. 2019 to Dec. 2019, 56 patients with thyroid cystic nodules (≥2cm) underwent ultrasound guided thyroid cystic nodule ablation in Department of Thyroid and Breast Surgery, Nanjing Hospital of Traditional Chinese Medicine. According to different ablation methods, the patients were divided into microwave ablation combined with anhydrous ethanol group and microwave ablation group. There were 36 cases in microwave ablation combined with anhydrous ethanol group and 20 cases in microwave ablation group. The volume reduction rate of thyroid nodules, the incidence of postoperative complications and the changes of thyroid function were compared between the two groups after treatment. Statistical analysis were performed using SPSS, version 21.0, the mean±SD deviation ( ± s) was used to describe the statistics, t-test was performed, and the adoption rate of counting data (%) was expressed by χ 2 test. The difference was statistically significant with P<0.05. Results:The nodule volume reduction rates of the microwave ablation combined with anhydrous ethanol group and microwave ablation group were (49.86±6.78) % vs (22.84±1.88) %, (67.57±5.84) % vs (47.25±7.09) % and (75.70±4.51) % vs (71.14±4.65) % at 3 months, 6 months and 12 months after operation, respectively. There was significant difference between the two groups ( P<0.001) . The incidence of postoperative complications in the two groups was 38.89% and 45.00% respectively, and there was no significant difference between the two groups ( P>0.05) , and all complications were cured within 2 months. There was no significant difference in thyroid function (T3, T4, FT3, FT4, TSH) between the two groups before and 12 months after operation ( P>0.05) . Conclusions:Microwave ablation combined with anhydrous ethanol is more effective in treatment of cystic thyroid nodules (≥2cm) than microwave ablation alone. It can significantly improve patients’symptoms and nodule volume reduction, and does not affect thyroid function. It can be used as a recommended option for treatment of cysticthyroid nodules.

Objective:To analyze the therapeutic effect of sural neurocutaneous flap combined with antibiotic-impregnated calcium sulfate and autogenous iliac bone graft of chronic calcaneal osteomyelitis.Methods:A retrospective analysis was peformed in 29 patients with chronic calcaneal osteomyelitis treated with sural neurocutaneous flap combined with antibiotic-impregnated calcium sulfate and autogenous iliac bone graft in the Xi′an Honghui Hospital Affiliated to Xi′an Jiaotong University from April 2013 to January 2020. There were 19 males and 10 females, with the age of (45.38±12.85) years, ranged from 22 to 67 years. The course of disease was (16.00±6.96) months, ranged from 6 to 36 months. The skin defect area was (41.9±15.9) cm 2, ranged from 11.8 to 86.8 cm 2. The causes of injury: 18 cases of high fall, 6 cases of traffic accidents, 3 cases of heavy rolling, the remaining 2 cases were machine strangulation and sharp stab wounds. The inflammatory markers [white blood cell (WBC), erythrocyte sedimentation rate (ESR), procalcitonin (PCT), C reactive protein (CRP)] and bone healing time were recorded before operation, 2, 4, 8 weeks and 6 months after operation. During the follow-up period, the flap texture, survival were observed, and the ankle-posterior foot function recovery was evaluated by the American Association of Foot and Ankle Surgery (AOFAS) score were observed before and after the operation, and the incidence of complications were recorded. The measurement data were expressed as mean±standard deviation ( ± s), and the t-test was used for inter-group comparison; the levels of WBC, ESR, PCT and CRP at different time points before and after operation were compared by repeated measurement ANOVA, and the LSD t-test was used for pairwise comparison. Results:All the 29 patients were followed up for (14.51±6.10) months, ranged from 6 to 30 months. All the flaps survived without abrasion, ulceration, or skin protrusion, and all patients could walk normally with shoes. There were 28 cases of stage I bone healing, with an average of (5.87±2.07) months, ranged from 3 to 12 months. The inflammatory indexes was significantly decreased at different time points after operation ( P<0.05). There was no significant difference between 6 months and 8 weeks after operation ( P>0.05), while there was significant difference at other time points ( P<0.05). The ankle-posterior foot score of AOFAS at 6 months after treatment was significantly higher than that before treatment (83.44±7.93 vs 55.37±8.07), the differences was statistically significant ( P<0.05). The clinical efficacy of foot function recovery was excellent in 12 cases, good in 15 cases and fair in 2 cases among 29 patients .The excellent and good rate was 93.1% (27/29). One patient recurred 1 month after operation and was re-implanted with antibiotic-loaded calcium sulfate mixed autogenous iliac bone after debridement, no recurrence was found. The total complication rate was 31.0%, but there was no significant impact on the patient's life in the later period. All patients returned to daily life and work. Conclusion:The treatment of chronic calcaneal osteomyelitis with sural neurocutaneous flap combined with antibiotic-impregnated calcium sulfate and autogenous iliac bone graft can effectively control infection, reconstruct calcaneal and soft tissue structure, promote functional recovery of affected limb, and ultimately improve the patient′s quality of life.

Objective:To evaluate the effectiveness of perioperative fasting abbreviation in traumatic patients with orthopaedic trauma and diabetes mellitus undergoing selective surgery.Methods:The patients were selected for this prospective nonrandomized controlled study who had undergone selective surgery from June 2019 to June 2021 at Department of Orthopaedic Trauma, Beijing Jishuitan Hospital. They were divided into an intervention group and a control group according to the wards where they stayed. The intervention group was fasted for solids from 0 o'clock on the surgery day and received oral solution with 6.25% maltodextrin which had been prepared by the nutritional department 3 hours prior to surgery. The control group was fasted for either liquids or solids from the midnight before surgery. All patients were evaluated according to the wake-up score and defensive reflex score after surgery. Once they were awakened, they were allowed slag-free drinks. Normal food was allowed if there was no discomfort after 2 hours. The 2 groups were compared in terms of basic information, actual preoperative fasting time, total amount of preoperative drinking, and postoperative time for initial drinking and eating. The perioperative subjective feelings (anxiety, thirst, hunger, nausea, fatigue, dizziness, sweating, stomach discomfort, etc.), grip strength and blood glucose were observed and compared between the 2 groups. Adverse reactions in the 2 groups were also observed.Results:A total of 135 patients were included, including 52 in the intervention group and 83 in the control group. The intervention group consisted of 22 males and 30 females aged from 30 to 84 years; the control group consisted of 39 males and 44 females aged from 29 to 81 years. There was no significant difference in the basic information between the 2 groups, showing comparability ( P>0.05). The intervention group had significantly shorter preoperative fasting time [3.5 (2.5, 6.3) h versus 12.0 (9.0, 16.0) h], significantly higher water intake before surgery [300 (200, 300) mL versus 100 (100, 200) mL], significantly shorter postoperative fasting time [0.08 (0, 1.25) h versus 2.00(0, 6.00) h], and significantly reduced time to return to normal diet [2.0 (2.0, 2.3) h versus 3.0(2.0, 6.0) h] than the control group (all P<0.05). The symptoms of anxiety, fatigue, sweating, and stomach discomfort in the intervention group were significantly fewer than those in the control group throughout the evaluation period. The thirst in the intervention group was significantly alleviated than that in the control group immediately after returning to the ward after surgery, and the dizziness and hunger were significantly alleviated than those in the control group when the patients left the ward to the operation room before surgery and immediately after returning to the ward. The symptom of nausea after returning to normal diet in the intervention group was significantly relieved compared with the control group. All the comparisons above showed statistically significant differences ( P<0.05). The blood glucose in the intervention group 2 hours after taking slag-free drinks was significantly higher than that in the control group ( Z=-2.108, P=0.035). There was no significant difference in the blood glucose between the 2 groups during other measurement periods ( P>0.05). There were no serious adverse reactions in either of the 2 groups. Conclusion:The protocol of perioperative fasting abbreviation may be safe and feasible for the patients with orthopaedic trauma and diabetes mellitus undergoing selective surgery, because it shows benefits of improving the patients' subjective feelings and stabilizing the blood glucose perioperatively.
