BACKGROUND: Surgery is a main method to reconstruct the stability of spine after compression fracture. But the reconstruction of spinal stability for patients undergoing conventional therapy remains unclear.OBJECTIVE: To explore whether spinal stability training is effective on improving pain and motor function of patients with vertebral osteoporotic fractures.METHODS: Patients with vertebral osteoporotic fractures were divided into two groups. The study group was treated with conventional treatments and individualized spinal stabilization training, while the control group received conventional treatments alone. All the subjects were evaluated before and after treatment by numeric pain rating scale (NPRS), 3-meter timed up and go (TUG) and Oswestry functional limitation index (OFLI). The results were compared between the two groups.RESULTS AND CONCLUSION: A total of 27 patients were included, including 16 patients in the study group and 11 in the control group. After 4-week treatment, TUG and OFLI in the study group decreased significantly compared with the control group (P < 0.05). But there was no statistical significance between the two groups in the level of NPRS and the amount of changes (P > 0.05). Symptoms and function of both groups were improved after treatments. Individualized spinal stability training is effective to restore the motor function and may be helpful for reducing pain for patients with vertebral osteoporotic fractures combined with conventional treatments.

ObjectiveTo observe the effect of muscle stimulating instrument on patients with cerebral palsy after microsurgical neurotomy of peripheral nerves.Methods77 patients with cerebral palsy after microsurgical neurotomy of peripheral nerves were divided into the treatment group (39 cases) and the control group (38 cases). Patients of two groups were treated with routine rehabilitation training, but muscle stimulating instruments treatment was added to patients of the treatment group. The muscle strength and motor ability of patients of two groups were followed up and compared.ResultsThe muscle strength and motor ability of the treatment group were better than that of control group during follow-up period(P<0.01).ConclusionMuscle stimulating instrument can accelerate the recovery of muscle strength and motor ability in patients with cerebral palsy after microsurgical neurotomy of peripheral nerves.

In order to clarify the chemical constituents in Qiliqiangxin capsule, a rapid ultra-performance liquid chromatography/orthogonal acceleration time-of-flight mass spectrometry (UPLC-Q-TOF/MS(E)) method was established. Forty peaks were identified on line using this method. The herbal sources of these peaks were assigned. The results implied that triterpenoid saponins, flavonoid glycosides, C21-steroids and phenolic acids were included in the main components of Qiliqiangxin capsule. The method is simple and rapid for elucidation of the constituents of Qiliqiangxin capsule and the results are useful for the quality control of Qiliqiangxin capsule.

Objective:Anatomical study of the cross-donor flap pedicled with the peroneal artery and the discussion of the effect of clinical application, so as to describe a new method for the repair of large-area soft tissue defects in the foot and ankle.Methods:From June 2016 to August 2019, 12 specimens of adult lower limbs were studied. The popliteal arteries were perfused with perchloroethylene-ethyl acetate-lead oxide and red perchloroethylene-ethyl acetate. The origin, number, outer diameter, course and distribution of perforating branches of the peroneal artery were anatomically observed. The source, distribution and anastomosis of the skin nutrient vessels in the posterolateral area of the calf were also studied. Relationship of the blood supply between the peroneal arteries and veins and the nutritional vessels of the sural nerve were observed. In 9 patients, the peroneal artery and vein were designed as the pedicle of cross-donor flap in the repair of large soft tissue defects of foot and ankle. The patients were entered follow-up through outpatient visits and telephone interviews.Results:Among the 12 adult specimens of lower limbs, there were 65 perforating branches from the peroneal artery, 4-7 branches on each side, with an average of (5.41±1.00) branches. The diameter of the penetrating deep fascia was(1.07±0.36) mm. The perforator branches were mostly distributed in 3 sections of 4.0-11.0 cm, 16.0-21.0 cm and 24.0-27.0 cm away from the lateral malleolus, accounting for 48%, 24% and 17% of the total number of perforators, respectively. The outer diameters of the perforator vessels were (0.92±0.26)(0.56-1.68) mm, (1.32±0.38)(0.60-2.14) mm, and (0.98±0.28)(0.62-1.36) mm. The length of the pedicle of the perforator vessels were (3.91±0.96)(2.15-5.78) cm, (5.34±0.50)(4.01-5.85) cm, and (3.31±1.15)(2.16-5.66) cm. The perforating branches in the 3 sections appeared constantly. The diameter of the vessels was≥0.5 mm with an average length of at(4.19±1.16)(2.15-5.85) cm. The vascular network of the flap in the posterolateral area of the calf was mainly composed of subdermal vascular network and deep fascial vascular network. The deep fascia vascular network in the posterolateral area of the calf had 3 obvious longitudinal chains, including the medial sural neurotrophic vascular chain, the small saphenous vein-sural nerve communicating branch vascular chain and the lateral sural neurotrophic vascular chain, which took the nutrient blood supply from the perforating branches of the peroneal artery also formed a longitudinal and transverse anastomosis between the perforating branches of the peroneal artery. In the clinical trials performed on 9 patients, all soft tissue defects of foot and ankle were repaired. The composite tissue flap survived without infection or necrosis. The follow-up was lasted for 12 months to 3 years. The postoperative function and the donor site appearance were good and the patients walked normally. According to the American Orthopaedic Foot and Ankle Association(AOFAS) foot scoring standard, the function of affected feet were evaluated. Five patients were excellent and 4 were good.Conclusion:The cross-donor flaps pedicled with peroneal arteries and veins has sufficient blood supply and a large area. It provides a method for the repair of large-area soft tissue defects in the foot and ankle.

Grassroots communities, as the forefront of the transformation of national system and mechanism, the reformation of social structure, the change of interest pattern, and the transition of ideological consciousness, have long been the focus of government work, academic research, and social practitioners. Based on the theory of collaborative governance, aiming at the problems existing in the emergency management of public health emergencies in grassroots communities at present, this paper put forward the construction measures of public health emergency collaborative governance system with grassroots communities as the core, including improving the grassroots community emergency management organizational structure, consolidating the standardized foundation of grassroots community emergency collaborative management, enhancing the awareness of grassroots community emergency collaborative management, and strengthening the interactivity of the grassroots community information communication system. It is hoped to provide necessary reference for promoting the reform of public health emergency governance system.

Tricuspid valve, also known as "forgotten valve" because of the high natural and surgical mortality. Transcatheter tricuspid valve replacement is an innovative surgical method to treat tricuspid regurgitation, which improves the prognosis of patients and is gradually being popularized in clinics. However, postoperative pulmonary complications are still the main causes affecting the rapid recovery and death. More and more medical experts begin to use preoperative inspiratory muscle training to reduce postoperative pulmonary complications and improve the quality of life of patients after cardiac surgery. However, there was no report on the effect of preoperative inspiratory muscle training on pulmonary complications after transcatheter tricuspid valve replacement. Therefore, for the first time, we boldly speculate that inspiratory muscle training can reduce pulmonary complications after transcatheter tricuspid valve replacement, and put forward suggestions for its treatment mechanism and strategy. But this rehabilitation intervention lacks practical clinical research. Unknown challenges may also be encountered, which may be a new research direction.
