The control group was given 500 mL dextran by venoclysis, once a day. The treatment group was given Shuilongjian as an additional drug. The therapeutic effect was evaluated according to the nerve function and the total capability in dealing with daily activities. Result All the 67 cases of cerebellar infarction were included in the analysis. The effective rate of the treatment group was better than that of control group with 83.3% and 58.1% (P

OBJECTIVE:To investigate advantages and disadvantages of preexisting metal post,casting metal post,ceramic post,and fiber post for clinical application,and to evaluate mechanical function,esthetical performance,and biocompatibility of fiber post.METHODS:Articles were retrieved with the key words of "fiber post,post-core restoration,dental materials,cement material,binder" in both English and Chinese between January 1990 and October 2008.Inclusion criteria:Articles addressing clinical application of fiber post for repairing residual root and crown were included.Exclusion criteria:Duplicated studies or Meta analysis was excluded.A total of 24 articles were included to investigate mechanical function,biocompatibility,and stickiness and retention of fiber post.RESULTS:Traditionally,metal post was easily folded and corrosive; in addition,esthetical performance and biocompatibility were still dissolved.Intension,hardness,esthetical performance,corrosion proof,fatigue resistance,and biocompatibility of fiber post were superior to those of traditional metal post.Furthermore,fiber post was able to highly adhere to root canal dentin via resin splicing agent,which could prolong useful life of dental prosthetic restoration,reduce root folded onset,and benefit for dental storage and repairing.Light mass of fiber post was another advantage compared with metal post.If the repair was failure,fiber post was easily taken out and reused.The combination of fiber post and resin nucleus was beneficial for dental prosthetic restoration which was highly closed to original structure of natural teeth.CONCLUSION:Fiber post was characterized by suitable elastic modulus,great esthetical repairing effect,reliable stickiness,easy identification and removal,high achievement ratio of repairing,and convenient operation; therefore,fiber post was a new and ideal material for clinical application.

Objective To explore the effects of motor imaginary therapy combined with occupational therapy on the function of upperlimbs hands and activities of daily living for stroke patients with hemiplegia. Methods 62 stroke patients with hemiplegia were divided intoobservation group (n=31) and control group (n=31). Both groups were treated with basic medication and occupational therapy while the observationgroup was treated additionally with motor imaginary therapy. The function of upper limbs and hands was assessed by Fugl-MeyerAssessment (FMA), and activities of daily living was assessed by Functional Independence Measurement (FIM) before and 2 months aftertreatment. Results There were significant difference between the two groups in the scores of FMA in the function of upper limbs and hands,and FIM 2 months after the treatment (P<0.01). Conclusion Motor imaginary therapy combined with occupational therapy can effectivelyimprove the functional outcomes of upper limbs and hands for stroke patients with hemiplegic, and can even effectively improve the functionalactivities of daily living.

BACKGROUND:Core decompression can delay early osteonecrosis of the femoral head, but cannot completely repair the necrotic femoral head. Eventualy, femoral head colapse, even bone necrosis, wil occur. OBJECTIVE:To explore the curative effect of implantation of gelatin sponge carrying Foxc2-transfected bone marrow mesenchymal stem cels on the repair of experimental femoral head necrosis in rabbits. METHODS:Forty New Zealand white rabbits were selected, and femoral head necrosis models were prepared successfuly in 24 of 40 rabbits. Then, model rabbits were randomized into four groups: blank control group (n=4) with no treatment, core decompression group (n=4), GFP group (n=8) subjected to core decompression and implantation of gelatin sponge carrying GFP-transfected bone marrow mesenchymal stem cels, and Foxc2 group (n=8) subjected to core decompression and implantation of gelatin sponge carrying Foxc2-transfected bone marrow mesenchymal stem cels. At 1, 2, 4 weeks after implantation, ELISA was used to detect Foxc2 protein levels in the transplanted region. At 4, 8, 12 weeks after implantation, MRI scan of the hip was performed, and femoral head tissues were taken and sliced into sections for hematoxylin-eosin staining to observe bone growth. At 12 weeks after implantation, histomorphometry measurement and transmission electron microscope observation were carried out. RESULTS AND CONCLUSION:At 1, 2, 4 weeks after implantation, Foxc2 was highly expressed in the femoral head in the Foxc2 group, which was significantly higher than that in the GFP group. At 4, 8, 12 weeks, only a few of new bone formed in the core decompression group and GFP group; at 12 weeks, fibrous tissues formed in the decompression channel. New bone formation was evident in the Foxc2 group, and at 12 weeks, the necrotic region was repaired completely. MRI findings showed normal femoral head morphology and signals in the Foxc2 group at 12 weeks, but there were decreased signals of the femoral head in the core decompression group and GFP group. These findings indicate that Foxc2-transfected bone marrow mesenchymal stem cel transplantationvia core decompression has good curative effects on experimental femoral head necrosis in animals.

Objective To observe the effect of finger-pressing combined with conventional rehabilitation therapy on the recovery of upper limb function after stroke.Methods A total of 60 cerebral stroke patients were randomly divided into an experimental group (n =30) and a control group (n =30).All patients were treated with conventional anti-symptomatic drugs but no anti-spasticity ones.The experimental group was given conventional rehabilitation and finger-pressing therapy,while the control group was given conventional rehabilitation only.Both groups were measured the motor function,using the upper-extremity portion of the Fugl-Meyer Scale,and the mean integrated electromyography (iEMG) output of biceps and flexor carpi radialis after the first finger-pressing treatment and 1 month later,so as to observe the immediate and continuous effects of finger-pressing therapy respectively.Results After the first session of finger-pressing therapy,the average Fugl-Meyer score(FMA) (12.63 ± 4.64) of the experimental group was significantly higher than in a pretest (12.13 ± 4.88) (P ＜ 0.05),while the iEMG of biceps (41.64 ± 9.22) and flexor carpi radialis (37.06 ± 7.02) were lower than before (P ＜ 0.01).One month after the treatment,compared with the control group,the average FMA (25.17 ± 5.93) and iEMG of biceps(34.42 ± 7.55) and flexor carpi radialis sEMG(30.63 ± 5.54) in the experimental group were significantly improved (P ＜ 0.01).Conclusions Finger-pressing therapy has significant and immediate effects in improving the upper extremity spasticity of stroke survivors.Combined with conventional rehabilitation therapy it can effectively reduce the upper extremity spasticity in stroke patients and significantly improve the upper extremity function.The combination is superior to conventional rehabilitation alone.

Objective To observe the effect of horizontal multi-joint arm continuous passive motion (CPM) training on muscle tension and strength of biceps brachii of patients with stroke. Methods 60 patients with stroke were divided into treatment group (n=30) and control group (n=30). All the patients accepted routine medication and rehabilitation. The treatment group accepted horizontal multi-joint arm CPM training in addition. Their surface electromyography of biceps brachii was analyzed with surface electromyography analysis system: tension and strength before and after treatment. Results The tension and strength of biceps brachii improved in both groups after treatment (P<0.05), and improved more in the treatment group than in the control group (P<0.05). Conclusion The horizontal multi-joint arm CPM training may relieve the muscle tension and enhance the strength of biceps brachii after stroke

BACKGROUND:Cell death and neuroinflammation are two important targets in the treatment of spinal cord injury.Pyroptosis is a programmed cell death closely related to neuroinflammation and targeted inhibition of pyroptosis after spinal cord injury is a promising therapeutic strategy. OBJECTIVE:To summarize the molecular mechanism,positive and negative regulatory factors and therapeutic strategies of pyroptosis in spinal cord injury. METHODS:The search terms were"spinal cord injury,pyroptosis,nucleotide-binding oligomerization domain-like receptor protein 3(NLRP3),Caspase,Gasdermin D(GSDMD),IL-1β,IL-18"and 93 English literatures included in PubMed and Web of Science were finally selected for review. RESULTS AND CONCLUSION:As a newly discovered programmed cell death,pyroptosis has been shown to play an important role in the secondary injury stage after spinal cord injury.Among the regulatory factors of pyroptosis after spinal cord injury,CD73,NRF2,GDF-11,dopamine,FANCC and miR-423-5P could inhibit pyroptosis,while TLR4 and Aopps could promote pyroptosis.In terms of treatment,the active ingredients of traditional Chinese medicine(paeonol,tripterine,betulinic acid,piperine,kaempferol,and camptothecin),exosomes of various cell origins,and some drugs(metformin,topotecan,lithium,zinc,and carbon monoxide-releasing molecule 3)can effectively inhibit pyroptosis and reduce secondary spinal cord injury,but the toxicity and specific dose of these drugs need to be further studied.The specific molecular mechanism by which pyroptosis aggravates spinal cord injury is still poorly understood.The role of non-classical pathways and other inflammasomes is worth further exploration.At present,the research on pyroptosis after spinal cord injury only stays at the animal experiment stage.There are no related clinical studies and no approved targeted therapeutic drugs.(6)The application of pyroptosis after spinal cord injury has great potential,and its specific regulatory mechanism should be further studied in the future to provide a new target for the treatment of spinal cord injury.

Spinal cord injury （SCI） is a severe central nervous system disease with poor prognosis， and the resulting severe sensory， motor or autonomic dysfunction greatly reduces patients' quality of life. Although considerable progress has been made in the treatment and care of SCI， the clinical efficacy and prognosis of SCI are not satisfactory due to the inability of drugs to be delivered directly to the site of SCI through the blood-spinal cord barrier and the fact that the local microenvironment after SCI is not conducive to the survival， differentiation， and proliferation of implanted stem cells. Due to its excellent mechanical properties， plasticity， and good biocompatibility and biodegradability， hydrogel can be used as a delivery system for loading stem cells or drugs， providing a favorable environment and controlling their release， and as a biological scaffold to support and guide axonal regeneration， which can effectively improve the therapeutic effect of spinal cord injury. This paper mainly reviews the classification and functional properties of hydrogels， and further discusses the research progress of hydrogels in SCI repair to improve the inhibitory microenvironment of spinal cord injury， promote nerve regeneration， promote angiogenesis， and promote the repair of the blood-spinal cord barrier， with the aim of providing a theoretical basis for the clinical application of hydrogels in the treatment of SCI as well as for exploring and developing future spinal cord regeneration strategies.

【Objective】 To evaluate the safety and effectiveness of Perioperative Transfusion Trigger Score (POTTS) in guiding surgical patients blood transfusion intraoperatively and postoperatively. 【Methods】 A total of 900 patients(perioperative Hb 60~100 g/L) from December 2017 to March 2021 were collected, including 251 males and 649 females, with ASA grading Ⅰ~Ⅳ, and randomly divided into experimental group and controls. In the experimental group, the allogeneic RBC transfusion trigger(Hb threshold) and transfusion units in anemia patients was determined by POTTS. While those in the controls were decided by physicians according to current guidelines concerning transfusion. The proportion and units of allogeneic RBC transfusion, the incidence of postoperative complications, the mortality of hospitalization and discharge for 4 weeks, Hb value, healing of surgical incision, ICU admission rate and ICU length of stay, length of hospitalization, etc were recorded. 【Results】 The proportion of allogeneic RBC transfusion in the experimental group(35.3%)were less than the controls(42.2%)(P<0.05). The units of allogeneic RBC transfused, incidence of postoperative complications and mortality in hospital and 4 weeks after surgery, healing of surgical incision (grade A/ grade B/ grade C), the Hb level 24 h after surgery and at discharge, the ICU admission rate and ICU length of stay, length of hospitalization were not significantly different between the groups. 【Conclusion】 The peri-operative allogeneic red blood cells transfusion guided by POTTS can reduce the proportion of allogeneic RBC transfusion, and is safe and effective.
