Objective:To compare the efficacy of internal fixation with video thoracoscopy-assisted rib plating and open thoracotomy in the treatment of multiple rib fracture.Methods:A retrospective cohort study was conducted to analyze the clinical data of 65 patients with multiple rib fracture who were admitted to Affiliated Bishan Hospital of Chongqing Medical University between May 2021 and May 2023, including 42 males and 23 females, aged 19-75 years [(51.6±7.0)years]. Of all, 33 patients were treated with internal fixation with video thoracoscopy-assisted rib plating (thoracoscopy group), while other 32 patients treated with internal fixation with open thoracotomy (thoracotomy group). Two groups were compared in terms of surgical incision length, intraoperative blood loss, surgical duration, duration of postoperative drainage tube placement, postoperative chest tube drainage, and length of hospital stay. Postoperative pain was assessed using the visual analogue scale (VAS) at 6, 12, 24, 48, and 72 hours postoperatively. Forced vital capacity (FVC), forced expiratory volume in the first second (FEV1), and peak expiratory flow (PEF) were detected preoperatively, at 7 days, 6 months postoperatively and at the last follow-up. The excellent and good rate of fracture healing was evaluated at 6 months postoperatively and at the last follow-up. The incidence of postoperative complications was also assessed.Results:All the patients were followed up for 12-24 months [(15.2±2.2)months]. The surgical incision length, intraoperative blood loss, and surgical duration were (4.3±1.5)cm, (65.2±15.0)ml, and (68.8±13.1)minutes in the thoracoscopy group, shorter or less than (7.2±1.7)cm, (93.3±16.3)ml, and (93.7±15.9)minutes in the thoracotomy group ( P<0.01). The duration of drainage tube placement, postoperative chest tube drainage volume and length of hospital stay were (3.8±1.5)days, (357.3±38.6)ml and (12.3±1.7)days in the thoracoscopy group, shorter or less than (5.9±1.8)days, (424.9±45.4)ml, and (18.6±2.5)days in the thoracotomy group ( P<0.01). At 6, 12, 24, and 48 hours postoperatively, the VAS scores in the thoracoscopy group were (5.1±1.6)points, (4.7±1.5)points, (4.2±1.5)points, and (3.9±1.3)points, significantly lower than those in the thoracotomy group [(8.4±1.8)points, (7.3±1.5)points, (6.3±1.3)points, and (5.2±1.2)points] ( P<0.01). There was no statistically significant difference in the VAS scores between the two groups at 72 hours postoperatively ( P>0.05). There were no statistically significant differences in FVC, FEV1 and PEF between the two groups preoperatively, at 6 months postoperatively and at the last follow-up ( P>0.05). At 7 days postoperatively, FVC, FEV1 and PEF were (4.17±0.25)L, (2.24±0.24)L, and (5.53±0.50)L/s in the thoracoscopy group, significantly higher than those in the thoracotomy group [(4.01±0.23)L, (2.12±0.21)L, and (5.23±0.42)L/s] ( P<0.05). At 6 months postoperatively, the excellent and good rate was 94% (31/33) in the thoracoscopy group and 97% (31/32) in the thoracotomy group ( P>0.05). At the last follow-up, the excellent and good rate in both groups were 100% ( P>0.05). The incidence of complications was 15% (5/33) in the thoracoscopy group, lower than 41% (13/32) in the thoracotomy group ( P<0.05). Conclusion:Compared with internal fixation with open thoracotomy in the treatment of multiple rib fracture, the internal fixation with video thoracoscopy-assisted rib plating has the advantages of less surgical trauma, milder pain at the early stage after surgery, earlier postoperative recovery of pulmonary function and fewer complications.

Opioid analgesics are currently known as the best analgesics. However， toxicity and side effects such as constipation， tolerance and addiction severely limit their clinical application. With the in-depth understanding of the signal transduction mechanism of opioid receptors and the continuous advancement of drug design technology， researchers have managed to develop many promising new methods to get low-toxic and more efficient opioid analgesics， which are different from the traditional morphine skeleton structure modifications. This article focuses on three new research strategies of G-protein biased activation，“ one drug-multiple targets” and peripheral activation. The basic principles of relative separation of analgesic activity and adverse drug reaction by each strategy are introduced， and the latest research progress of representative drugs is briefly reviewed. Among them， the recently approved novel opioid analgesics oliceridine and tegileridine are G-protein biased μ-opioid receptor agonists， Cebranopadol is a typical “one drug-multiple targets” analgesic， and NFEPP is a representative drug of peripheral opioid receptor agonists. The above several strategies complement each other and provide reference for the development of new opioid analgesic drugs.

Objective:To assess the effectiveness of a 6-month Ba Duan Jin exercise program in improving the balance of community-dwelling older adults.Methods:A two arms, parallel-group, cluster randomized controlled trial was conducted in 1 028 community residents aged 60-80 years in 40 communities in 5 provinces of China. Participants in the intervention group (20 communities, 523 people) received Ba Duan Jin exercise 5 days/week, 1 hour/day for 6 months, and three times of falls prevention health education, and the control group (20 communities, 505 people) received falls prevention health education same as the intervention group. The Berg balance scale (BBS) score was the leading outcome indicator, and the secondary outcome indicators included the length of time of standing on one foot (with eyes open and closed), standing in a tandem stance (with eyes open and closed), the closed circle test, and the timed up to test.Results:A total of 1 028 participants were included in the final analysis, including 731 women (71.11%) and 297 men (28.89%), and the age was (69.87±5.67) years. After the 3-month intervention, compared with the baseline data, the BBS score of the intervention group was significantly higher than the control group by 3.05 (95% CI: 2.23-3.88) points ( P<0.001). After the 6-month intervention, compared with the baseline data, the BBS score of the intervention group was significantly higher than the control group by 4.70 (95% CI: 4.03-5.37) points ( P<0.001). Ba Duan Jin showed significant improvement ( P<0.05) in all secondary outcomes after 6 months of exercise in the intervention group compared with the control group. Conclusions:This study showed that Ba Duan Jin exercise can improve balance in community-dwelling older adults aged 60-80. The longer the exercise time, the better the improvement.

Objective:To compare the clinical efficacy of rotator cuff repair combined with transposition of the long head of the biceps tendon in the treatment of massive rotator cuff tears with or without subscapularis injury.Methods:A total of 73 patients with massive rotator cuff tears who underwent arthroscopic rotator cuff repair combined with transposition of the long head of the biceps tendon in the Department of Upper Arm, Sichuan Orthopaedic Hospital from January 2019 to September 2022 were retrospectively analyzed, including 35 males and 38 females, aged 58.8±7.6 years (range, 46-73 years). There were 11 cases on the left side and 62 cases on the right side. Causes of injuries: 6 cases of car accidents, 13 cases of fall injuries, 54 cases of no obvious cause of injury. The patients were divided into subscapularis injury group (37 cases) and no subscapularis injury group (36 cases) according to the subscapularis injury or not. The visual analogue scale (VAS), Constant - Murley score, University of California Los Angeles (UCLA) shoulder score and range of motion were used to evaluate shoulder pain and functional improvement. MRI of the shoulder was taken at the final follow-up and the rotator cuff was assessed for retear using Sugaya grading.Results:All patients successfully completed the operation. The VAS score at 1 year postoperatively in the group without subscapularis injury was 0.58±0.87, which was less than 1.16±1.14 in the group with subscapularis injury ( t=-2.426, P=0.018). The Constant-Murley score and UCLA score at 1 year postoperatively in the group without subscapularis injury were 94.03±6.19 and 32.94±2.59, respectively, which were greater than those of the group with subscapularis injury, which were 86.51±11.96 and 30.38±3.33, and the difference was statistically significant ( P<0.05). Anterior flexion and body external rotation at 1 year postoperatively in the group without subscapularis injury were 137.22°±26.79° and 54.72°±13.20°, which were greater than those in the group with subscapularis injury of 121.08°±22.83° and 38.65°±17.19°, and the difference was statistically significant ( P<0.05), and the difference between the two groups in body internal rotation was not statistically significant ( P>0.05). The subacromial spacing at 1 year postoperatively was 9.4±1.3 mm in the group without subscapularis injury and 9.0±1.5 mm in the group with subscapularis injury, and the difference was not statistically significant ( t=1.318, P=0.192). There were 2 cases of rotator cuff retear 1 year after surgery without subscapular muscle injury and 5 cases of subscapular muscle injury. Conclusion:The clinical efficacy of arthroscopic rotator cuff repair combined with transposition of the tendon of the long head of the biceps tendon in the treatment of massive rotator cuff tears with or without subscapularis muscle injury is satisfactory, and the improvement of pain and function is more obvious in patients without subscapularis muscle injury.

It is believed that the basic pathogenesis of oculomotor nerve paralysis （ONP） is qi and blood depletion and channel obstruction. Taking channel pattern differentiation as the core， it is recommended to use acupuncture mainly based on location， syndrome and channel deficiency-excess differentiation. Location and channel tropism differentiation mainly follows the principle of “where the channels and collaterals pass， the main treatment can reach”， and commonly uses acupuncture points on Dumai （督脉）， the hand Shaoyang （少阳） Sanjiao （三焦） channel， the hand Taiyang （太阳） small intestine channel， three yang channels of the foot， the hand Shaoyin （少阴） heart channel， the foot Jueyin （厥阴） liver channel， and others， and combines scalp acupuncture with electro-acupuncture to enhance channel stimulation. Pattern and channel tropism differentiation is to differentiate the entered channel according to clinical symptoms and zang-fu patterns. The differentiation of deficiency-excess should be payed attention to， and the principle of “supplementing the deficiency， and draining the excess” should be followed. The supplementing and draining method should be used rationally by considering the differences in the supplementing and draining acupoints themselves， as well as the actual condition of the patients. Simultaneously， it is suggested to combine manipulation and stimulation amount and effect in clinical practice.
