Objective:To observe the effect of observing good swallowing on the swallowing action of stroke survivors with dysphagia.Methods:Eighteen stroke survivors with dysphagia were randomly divided into a treatment group ( n=9) and a control group ( n=9). In addition to routine swallowing rehabilitation therapy, the treatment group was asked to simulate swallowing after watching a video of normal people′s swallowing action. They did so 5 times a week for 10 minutes, while the control group just watched landscape videos at the same time. The treatment lasted 8 weeks. Before and after the treatment, both groups were assessed using the eating assessment tool (EAT-10), the functional oral intake scale (FOIS) and the penetration and aspiration scale (PAS). Functional magnetic resonance imaging (fMRI) was also used to observe their swallowing action. Results:There was no significant difference between the two groups in any of the measurements before the treatment. After the 8 weeks of treatment the average EAT-10, FOIS and PAS scores of the treatment group were all significantly better than before the treatment and better than the control group′s averages at the time. fMRI showed significantly more areas activated in the precuneus, parietal lobe, posterior central gyrus, BA7, BA5, frontal lobe and paracentral lobule in the treatment group compared with before the intervention and also more than in the control group.Conclusions:Observing proper swallowing action can improve dysphagia and activation of the swallowing-related brain areas of stroke survivors.

Objective:To observe any effect of repeated unilateral high frequency transcranial magnetic stimulation (rTMS) on the swallowing function and functional magnetic resonance images of dysphagic stroke survivors.Methods:Twenty stroke survivors with dysphagia were randomly divided into a treatment group ( n=10) and a control group ( n=10). Both groups received traditional swallowing rehabilitation training, while the treatment group was additionally provided with high frequency rTMS over the cortical area of the suprahyoid muscle group of the healthy contralateral cerebral hemisphere. The stimulation frequency was 5Hz and the stimulation intensity was 80% of the resting movement threshold. During the 20-minute treatment, there was a 20-second interval between each 2-second dose of stimulation. Before and after the treatment, both groups were evaluated using the Eating Assessment Tool-10 (EAT-10), a swallowing functional communication measurement (FCM) and the modified Mann Assessment of Swallowing Ability (MMASA). In addition, functional magnetic resonance imaging was used to observe any changes in the relevant brain regions. Results:After the treatment the average EAT-10, FCM and MMASA scores of both groups were significantly better than those before the treatment, with the treatment group′s averages significantly superior to those of the control group. After the treatment, the activation range of the parietal lobe, the superior parietal lobule, the BA7 region and the BA40 area in the treatment group was significantly larger than before the treatment and larger than the control group′s ranges.Conclusions:Repeated high-frequency transcranial magnetic stimulation of the cortical area of the suprahyoid muscles in the contralateral cerebral hemisphere can improve dysphagia and promote the activation of brain areas related to swallowing after a stroke.

Objective To explore the value of endocervical curettage (ECC) in the detection of high-grade cervical squamous intraepithelial lesion (HSIL). Methods We retrospectively analyzed the clinical features and colposcopical characteristics of 678 female patients with complete clinical data. Results Among 678 cases, 391 cases were confirmed by cervical biopsy only and 7 cases by ECC only (57.67% vs. 1.03%, P < 0.001). ECC checked out 287 HSIL patients (42.33%, including cervical biopsy positive and negative cases) and cervical biopsy checked out 671 HSIL cases (98.97%, including ECC positive and negative cases). There were 68 positive ECC cases in the conversion area of Type 1+Type 2 and 247 positive ECC cases in the conversion area of Type 3(33.33% vs. 52.11%, P < 0.001). The positive rates of ECC in patients≥45 years old and < 45 years old were 145 and 170, respectively (55.13% vs. 40.96%, P < 0.001). Conclusion The cervical biopsy plays a dominant role in the detection of HSIL, and ECC can only be used as a supplement to it. Female patients older than 45 years or with Type 3 transformation zone examined by colposcopy should be concerned with cervical lesions.

The epidemic of COVID-19 has become the topmost public health threat worldwide. The authors suggested that in addition to strengthening the organization and leadership of the abovementioned work, greater attention be paid to establishing and improving the prevention and control mechanism.Furthermore, special efforts should be given to the safety of the medical workers, by strengthening their infection monitoring and outbreak management. Medical workers in different work areas and positions should be placed under careful protection with due cleaning and disinfection measures. The protection during specimen collection, transportation and medical waste management should also be prioritized. Such special issues in the management of pediatric patients, as allocation of nurses, the screening and management of caregivers, the problem of breastfeeding, and the disinfection of children′s toys and diapers were discussed. This paper also put forward management suggestions for the outpatient department, isolation ward and other key departments, which aim to guide the prevention and control of COVID-19 nosocomial infection in the pediatric outpatient and ward.

The pneumonia caused by the novel coronavirus (2019-nCoV), which began in December 2019, has become the most serious public health problem, threatening people's health and life. This threat is posing a severe challenge on the diagnosis and treatment of 2019-nCoV infection, the prevention and control of hospital cross infection of medical staff. It is suggested that in addition to strengthening the organization and leadership of the abovementioned work, establishing and improving the prevention and control mechanism deserve greater attention. Furthermore, special attention should be given to the safety of the medical staff, strengthening their infection monitoring and outbreak management. Medical staff in different work areas and positions should be placed under careful protection, cleaning and disinfection measures. The protection during specimen collection, transportation and medical waste management should also be prioritized. This paper also put forward management suggestions for the outpatient department, isolation ward and other key departments. These measures are proposed to provide a guidance for the prevention and control of 2019-nCoV nosocomial infection in the pediatric outpatient and ward.

Objective:To observe the effect of applying repetitive transcranial magnetic stimulation (rTMS) on swallowing function and auditory evoked potentials in the brain-stems of stroke survivors with dysphagia.Methods:Sixty stroke survivors with dysphagia were randomly assigned to an observation group and a control group, each of 30. Both groups were given 30 minutes of routine swallowing training 6 times a week for 5 weeks, while the observation group was additionally provided with two-second bursts of rTMS on the left and right brain hemispheres alternately for 20 minutes daily. The frequency was 3.0Hz and the strength was 80% of the resting motor threshold (RMT), with an interval of 10 seconds between bursts. Before and after the treatment, both groups′ swallowing was assessed using the functional communication measure (FCM) and the modified Mann swallowing capacity evaluation scale (MMASA). Brainstem auditory evoked potentials (BAEP) were recorded to detect any changes in the peak latency (PL) and inter-peak latency (IPL). The clinical efficacy was also observed.Results:After the treatment, the average FCM results of both groups had improved significantly, but the observation group had improved significantly more. The average MMASA total scores and the average scores on all the sub-items had improved significantly more in the observation group except for the expressive speech disorder and anarthria scores. After the treatment, improvement was observed in respiration, anarthria, range of motion of the tongue muscles, strength of the tongue muscles, gag reflex and soft palate movement compared with before the intervention. Peak and inter-peak latencies had also improved significantly more in the observation than in the control group, on average.Conclusions:rTMS combined with conventional swallowing training can significantly improve the swallowing of dysphagic stroke survivors, and shorten the PL of the BAEP so as to better regulate deglutition.

Objective To explore the effects of action observation therapy on upper-extremity motor function after ischemic stroke and on the motor cortex using functional magnetic resonance imaging (fMRI).Methods Forty patients with ischemic stroke were randomly assigned to an observational group (n =20) or a control group (n =20).Both groups received conventional rehabilitation,while the observational group was additionally provided with action observation therapy for 8 weeks.Both groups were assessed using the Fugl-Meyer assessment (FMA) and the Barthel index (BI) before and after the 8 weeks of treatment and functional magnetic resonance imaging was performed before treatment.Two months after the treatment,nine patients of the experimental group and 8 of the control group who continued to receive their respective treatments after discharge were again assessed using functional magnetic resonance imaging.Results After the treatment the average FMA score and BI score of both the observational group and the control group had increased significantly.The increase in the average FMA score of the observational group was significantly greater than that of the control group.However,there was no significant difference between the two groups in the increases in BI score after 8 weeks of treatment.The fMRI results showed that there was a significantly greater rise in activity in the bilateral precentral gyrus,parietal lobe and the supplementary motor area of the patients in the observational group after the treatment compared with the control group.Conclusion Action observation therapy can improve upper extremity motor function and performance in the activities of daily living after ischemic stroke and induce changes in the excitability of the cerebral motor cortex.

Objective To explore the effectiveness of a respiratory function training instrument with stable chronic obstructive pulmonary disease (COPD) patients.Methods Sixty-seven COPD patients in the stable period were randomly divided into a treatment group of 36 and a control group of 31 using a random number table.Both groups were given conventional pulmonary rehabilitation,including half-closed lip respiration,abdominal respiration and upper limb training.The treatment group was additionally provided with 30 minutes of respiratory training using a respiration function training instrument 5 times per week for 6 months.Both groups were assessed for their mobility,life quality and pulmonary function using the 6-minute walk test (6 MWT),a COPD assessment test (CAT),the BODE index,forced vital capacity (FVC),forced expiratory volume in one second (FEV1) and surface electromyography (SEMG) of the respiratory muscles before and after the 6-month intervention.Results Before the treatment there were no significant differences between the two groups in terms of any of the measurements.After the treatment,significant improvement was observed in the average 6 MWT,CAT,BODE index and SEMG results in both groups,but with significantly greater improvement in the treatment group.The average FVC and FEV1 results did not improve significantly,so after the intervention there was still no significant difference between the groups.Conclusions Respiratory training using the pulmonary function training instrument can improve the mobility,life quality and the functioning of the respiratory muscles of COPD patients in the stable period.

Objective To explore any effect of combining urodynamic analysis with individualized bladder training in rehabilitating neurogenic bladder dysfunction after spinal cord injury.Methods Urology patients who had suffered a spinal cord injury were randomly divided into an experimental group and a control group.Both groups were given routine drugs and intermittent catheterization based on a urodynamics analysis using the Laborie urodynamic analyzer.The experimental group also received individualized bladder training for eight weeks.The bladder balance time and urinary infection rate of both groups were recorded 2,4,6 and 8 weeks after the intervention.Results After treatment,all of the patients wcrc able to achieve bladder balance,but the average bladder balance time of the experimental group was significantly shorter than that of the patients in the control group with similar injuries.After 2,4,6 and 8 weeks the incidence of urinary infection in the experimental group was significantly lower than in the control group.Moreover,after the treatment the average bladder storage volume (VH2O),bladder compliance (BC),bladder pressure (Pves) and detrusor pressure (Pdet) of both groups were significantly better than before the treatment,but the results of the experimental group were,on average,significantly better than those in the control group.Conclusion Individualized bladder training can effectively promote bladder balance and reduce the risk of urinary infection after spinal cord injury.

Endoplasmic reticulum plays a key role in both basic structure formation and function performance of microenviron-ment. Endoplasmic reticulum homeostasis unbalance caused by endoplasmic reticulum stress has become a hot research topic in recent years. This paper focuses on the role of endoplasmic retic-ulum stress in ischemic stroke. Research progress of related sig-naling pathways were reviewed, especially mechanisms through which endoplasmic reticulum stress trigger the inflammatory reac-tion, so as to provide a new research method for prevention of is-chemic stroke.
