Objective To explore the impact of the clinical internship model at the on-campus rehabilitation outpatient clinic on the clinical practice abilities and employment intentions of students in the physical therapy program.Methods A total of 60 students from the 2020 cohort of the Rehabilitation Physical Therapy program at Kunming Medical University were selected as research subjects.In the first semester of their sophomore year,they were randomly divided into two groups:the three-phase clinical internship group at the on-campus rehabilitation outpatient clinic(n=30)and the conventional clinical internship group(n=30).The three-phase clinical internship group completed their clinical internship in three phases according to the training objectives at the on-campus rehabilitation outpatient clinic,while the conventional clinical internship group completed their internship according to the requirements of the internship syllabus.At the end of all clinical internships,assessments were conducted using a comprehensive theoretical examination of core professional courses,the Assessment of Physiotherapy Practice(APP),and an employment intention survey to evaluate the outcomes of the internships for both groups.Results After completing all internship tasks,there was no statistically significant difference in the scores of the comprehensive theoretical examination of core professional courses between the two groups(P>0.05).Similarly,there was no statistically significant difference in the total scores of the physiotherapy clinical practice assessment between the two groups(P>0.05).However,in the detailed assessments,the three-phase internship group outperformed the conventional group in professional behavior,communication,and evaluation(P<0.05).There were no statistically significant differences between the two groups in analysis and planning,intervention,evidence-based practice,and risk management(P>0.05).In the employment intention survey,70%of students in the three-phase internship group expressed a willingness to work in rehabilitation outpatient clinics or clinics,while only 46.6%of the conventional group did so.The comparison of employment intentions between the two groups showed a statistically significant difference(P<0.05).Conclusion The three-phase apprenticeship model of the on-campus rehabilitation clinic not only improves students'clinical practice ability,but also increases their confidence in seeking employment in the rehabilitation clinic,thus broadening the employment pathway for physiotherapy students.

Objective To explore the immediate,long-term,and delayed effects of spiral stabilizing muscle chain technique compared to static distraction and Proprioceptive Neuromuscular Facilitation(PNF)stretching techniques on the flexibility of hip flexors.Methods Ninety subjects were randomly divided intothree groups of 30 each.Group 1 underwent the static stretching of the hip joint.Group 2 received PNF stretching,and Group 3 participated in SPS training.All participants were measured for hip extension angle to assess hip flexor flexibility before training,immediately after the first training session,at the end of 4 weeks of training,and 2 weeks after training cessation.Results Within-group comparisons showed significant increases in hip extension angles after one training session,after 4 weeks of training,and after 2 weeks of cessation compared to pre-training(P＜0.05).Between-group comparisons indicated no statistically significant differences in hip extension angle improvements among the three groups after one training session,after 4 weeks of training,and after 2 weeks of cessation(P＞0.05).Conclusion SPS training,static stretching,and PNF stretching all demonstrate good immediate,long-term,and delayed effects on improving hip extension angles,with consistent stretching outcomes.

Objective:To observe any effect of transplanting bone marrow mesenchymal stem cells (BMSCs) on microglia and neuron expression in newborn mice with hypoxic-ischemic brain damage (HIBD).Methods:Sixty 10-day-old C57BL/6 mice were randomly divided into a sham operation group, a hypoxic-ischemia group, a placebo group and a stem cell group, each of 15. The hypoxia-ischemia model was induced in the hypoxia-ischemia, placebo and stem cell groups, while the sham operation group was sutured after the neck incision. After successful modeling, the rats in the stem cell group were injected with BMSCs into the bregma while those in the placebo group received phosphate buffered saline. Seven days later, brain tissue was resected and its structure was observed using transmission electron microscopy. Immunofluorescence staining was performed to observe the expression of microglia and neurons in the left cerebral cortex.Results:Seven days after stem cell transplantation, the neuron morphology had improved and nerve fiber swelling was relieved in the stem cell group. The average expression of neurons was significantly greater in the stem cell group compared with the hypoxic-ischemia and placebo groups, while the expression of microglia was significantly lower.Conclusions:Bone marrow mesenchymal stem cells may induce neuron regeneration and reduce inflammatory response by inhibiting the expression of microglia, at least in neonatal rats modeling hypoxic-ischemic brain injury.

Objective:To study the efficacy of low-intensity focused ultrasound (LIFU) on neuropathic pain (NP) in mice, and its effect on the activation of astrocytes and the expression of pro-inflammatory cytokines were discussed.Methods:Thirty-six male C57BL/6J mice were randomly divided into three groups: sham operation (Sham) group and chroinc constriction injury (CCI) model group and treatment (CCI+ LIFU) group, 12 mice in each group.NP model was established by CCI on the sciatic nerve. The group of CCI+ LIFU received LIFU treatment for the anterior cingulate cortex (ACC) on the 7th day after surgery, the mechanical withdrawal threshold (MWT) on the affected side of mice was measured at preoperation 3, 6, 12, 18, 24, and 27 days after operation, respectively, H&E staining was used to observe pathological morphological changes in the ACC region, the expression levels of ACC region AQP4 and GFAP protein were detected by Western Blot and immunofluorescence, and the expression levels of ACC region pro-inflammatory cytokines IL-1β and TNF-α were detected by enzyme-linked immunosorption assay.Results:Compared with Sham group, MWT in the CCI group decreased from the 3rd day until the 27th day after surgery( P<0.05); Compared with the CCI group, the MWT in the CCI+ LIFU group increased on the 24th day after surgery, and was significantly higher than that of the CCI group on the 24th and 27th day after surgery ( P<0.05); LIFU stimulation did not produce significant pathological changes in the ACC region; Western Blot and immunofluorescence showed that AQP4 and GFAP protein expression in the ACC region were upregulated ( P<0.05) after peripheral nerve injury, while AQP4 and GFAP protein expression was downregulated after LIFU treatment ( P<0.05); Enzyme-linked immunosorbents showed that the expression of pro-inflammatory cytokines IL-1β and TNF-α in the region of ACC was upregulated ( P<0.05) after peripheral nerve injury, while the expression of IL-1β and TNF-α was downregulated after LIFU treatment ( P<0.05). Conclusions:LIFU can effectively relieve mechanical pain sensitivity symptoms in mice induced by CCI, possibly by inhibiting activation of astrocytes and neuro-inflammatory responses.

Objective:To evaluate the clinical efficacy of hydrotherapy in the treatment of children with spastic cerebral palsy (CP).Methods:The China National Knowledge Infrastructure, Wanfang databases, CQVIP databases, PubMed and the Cochrane library were electronically searched for reports published before November 2018 of randomized and controlled trials (RCTs) of hydrotherapy for treating children with spastic CP. Two researchers screened the literature independently, extracted data and assessed the risk of bias in the included studies. The meta-analysis was performed using version 5.3 of the RevMan software.Results:A total of 6 RCTs were included, covering 464 patients. It was found that hydrotherapy combined with conventional rehabilitation was significantly more effective than conventional rehabilitation alone.Conclusions:It has been proved that hydrotherapy can improve the symptoms of children with spastic CP, relieve their spasticity and promote better motor function.
