Effects of robot-assisted upper limb training combined with functional electrical stimulation in stroke patients: study protocol for a randomized controlled trial.

INTRODUCTION: About 17-80% stroke survivors experience the deficit of upper limb function, which strongly influences their independence and quality of life. Robot-assisted training and functional electrical stimulation are commonly used interventions in the rehabilitation of hemiplegia upper extremities, while the effect of their combination remains unclear. The aim of this trial is to explore the effect of robot-assisted upper limb training combined with functional electrical stimulation, in terms of neuromuscular rehabilitation, compared with robot-assisted upper limb training alone. METHODS: Individuals (n = 60) with the first onset of stroke (more than 1 week and less than 1 year after stroke onset) will be considered in the recruitment of this single-blinded, three-arm randomized controlled trial. Participants will be allocated into three groups (robot-assisted training combined with functional electrical stimulation group, robot-assisted training group, and conventional rehabilitation therapies group) with a ratio of 1:1:1. All interventions will be executed for 45 min per session, one session per day, 5 sessions per week for 6 weeks. The neuromuscular function of the upper limb (Fugl-Meyer Assessment of upper extremity), ability of daily life (modified Barthel Index), pain (visual analogue scale), and quality of life (EQ-5D-5L) will be assessed at the baseline, at the end of this trial and after 3 months follow-up. Two-way repeated measures analysis of variance will be used to compare the outcomes if the data are normally distributed. Simple effects tests will be used for the further exploration of interaction effects by time and group. Scheirer-Ray-Hare test will be used if the data are not satisfied with normal distribution. DISCUSSION: We expect this three-arm randomized controlled trial to explore the effectiveness of robot-assisted training combined with functional electrical stimulation in improving post-stroke upper limb function compared with robot-assisted training alone. TRIAL REGISTRATION: Effect of upper limb robot on improving upper limb function after stroke, identifier: ChiCTR2300073279. Registered on 5 July 2023.

Group A Streptococcal infections are still not negligible / 中华实用儿科临床杂志

Recently, there have been outbreaks of Group A Streptococcus (GAS) infection in foreign countries.The reasons are varied.With the relaxation of control for severe acute respiratory syndrome coronavirus 2(SARS-CoV-2) infection, it is very likely that concurrent or secondary GAS infection peaks will occur at the same time as the number of Corona Virus Disease 2019(COVID-19) cases increases dramatically.Children are generally susceptible to GAS and are more vulnerable.In response to possible outbreaks, early identification of GAS infections and rational use of antibiotics are particularly important.

Immune debt and its impact in children during severe acute respiratory syndrome coronavirus 2 epidemic / 中华实用儿科临床杂志

Non-pharmaceutical interventions (NPIs) implemented during the severe acute respiratory syndrome coronavirus 2(SARS-CoV-2) epidemic have been proven to be effective in blocking the spread of the epidemic.While reducing SARS-CoV-2 transmission, NPIs also reduce children exposure to other pathogens, leading to a decline in the incidence of many viral and bacterial infections.The reduction in contact with viruses and bacteria and the delay or interruption of routine immunization during SARS-CoV-2 epidemic have resulted in insufficient immune stimulation of pathogens on the population, leading to an increase in susceptible populations and a decline in herd immunity, forming the immune debt during SARS-CoV-2 epidemic.After reducing or lifting NPIs, the incidence of some viral or bacterial infectious diseases was significantly higher than pre-epidemic.In this review, the definition, source, impact and strategies of immune debt during epidemic period were expounded, inorder to improve clinicians′ attention and understanding of immune debt and optimize the prevention of children′s infectious diseases.

RESULTS The stem of C. gracile was slender， square columnar， covered by white fluff， the surface was grayish green or greenish brown； epidermal cells， non-glandular hairs， cortical cells and so on were seen in the cross section of the stem. Non-glandular hairs， ducts， wood fibers， mesophyll cells and so on could be seen in the powder. Results of TLC identification showed that there were spots of the same color in the chromatographic position corresponding to the chromatographic position of buddlejasaponin Ⅳb control. The contents of water， total ash， acid-insoluble ash， dilute ethanol extract and rosmarinic acid in 10 batches of samples were 8.69%-12.33%， 5.96%-13.33%， 0.14%-3.29%， 18.57%-32.61%， 0.35%-0.82%， respectively. The average values were 10.10%， 9.73%， 1.06%， 23.54% and 0.56%， respectively. CONCLUSIONS The established method can be used for quality control of C. gracile. It is preliminarily proposed that the ash content in the herb should not exceed 12.0%， the total ash content should not exceed 12.0%， the acid-insoluble ash content should not exceed 1.5%， the dilute ethanol extract should not be less than 18.0%， and the rosmarinic acid content should not be less than 0.45%.

Delayed Hemorrhage Followed by Vertebral Artery Injury during Cervical Anterior Controllable Antedisplacement and Fusion Surgery: Case Report and Literature Review.

BACKGROUND: Vertebral artery injury (VAI) during cervical spine surgery is rare. Anterior controllable ante-displacement and fusion (ACAF) surgery is a novel technique for treating degenerative cervical spine disorders, especially ossification of the posterior longitudinal ligament. To date, there have been no reports of VAI during cervical ACAF surgery. Here, we report a rare case of perioperative complication of VAI during ACAF surgery. The available English literature that provides treatment instructions were reviewed. CASE PRESENTATION: A patient diagnosed with mixed ossification of the posterior longitudinal ligament (OPLL) underwent ACAF surgery from C2-C6. Two level transverse foramina were ruptured, and severe bleeding was encountered during ACAF osteotomy. Hemostatic tamponade was performed using bone waxes. The patient had delayed hemorrhage on postoperative day 6. Emergence angiography revealed two vertebral artery pseudoaneurysms in the ruptured transverse foramina. A balloon-expandable covered stent was deployed to treat the pseudoaneurysm. The patient recovered without complications. CONCLUSION: ACAF surgery is a good choice for multiple-level OPLL disease, but special attention should be paid to VAI in the perioperative period. Intraoperative tamponade with bone wax and postoperative digital subtraction angiography (DSA) are effective in preventing disaster-related hemorrhage.

Study on knowledge, attitudes and practices of pulse oximetry among pediatric healthcare providers in China and their influencing factors / 中华实用儿科临床杂志

Objective:To investigate the knowledge, attitudes, and practices (KAP) of pulse oximetry among pediatric healthcare providers in China and analyze the factor influencing the KAP.Methods:A self-developed questionnaire was used for an online research on the KAP of 11 849 pediatric healthcare providers from 31 provinces, autonomous regions, and municipalities of China from March 11 to 14, 2022.The factors influencing the KAP of pulse oximetry among pediatric healthcare providers were examined by Logistic regression. Results:The scores of KAP, of pulse oximetry were 5.57±0.96, 11.24±1.25 and 11.19±4.54, respectively.The corresponding scoring rates were 69.61%, 74.95%, and 55.99%, respectively. Logistic regression results showed that the gender and working years of pediatric healthcare providers, the region they were located, and whether their medical institution was equipped with pulse oximeters were the main factors affecting the knowledge score (all P<0.05). Main factors influencing the attitude score of pediatric healthcare providers included their knowledge score, gender, educational background, working years, region, medical institution level, and whether the medical institution was equipped with pulse oximeters (all P<0.05). For the practice score, the main influencing factors were the knowledge score, gender, age, and whether the medi-cal institution was equipped with pulse oximeters (all P<0.05). Conclusions:Chinese pediatric healthcare providers need to further improve their knowledge about and attitudes towards pulse oximetry.Pulse oximeters are evidently under-used.It is urgent to formulate policies or guidelines, strengthen education and training, improve knowledge and attitudes, equip more institutions with pulse oximeters, and popularize their application in medical institutions.

Objective:To analyze the genetic characteristics of Group A Streptococcus (GAS) isolated from the pharynx of children with scarlet fever-like erythema. Methods:Pharyngeal GAS isolates were collected retrospectively from children with scarlet fever-like erythema admitted in the Department of Dermatology, Beijing Children′s Hospital, Capital Medical University from June 2019 to February 2020.PCR and sequencing were used to detect emm genotyping and superantigen genes( speA, speB, speC, speF, speG, speH, speI, speJ, speK, speL, speM, ssa and smeZ) of the isolates.Data were compared by the chi-square test or Fisher′ s exact test between groups. Results:A total of 147 GAS strains were collected.The main emm genotypes were emm1.0 in 76 strains (51.70%) and emm12.0 in 60 strains (40.82%). Other 7 emm genotypes were all found in less than 5 strains.The detection rate of speF, smeZ, speG, speC, speB and ssa were as high as 100.00%(147/147 strains), 100.00%(147/147 strains), 99.32%(146/147 strains), 95.24%(140/147 strains), 94.56%(139/147 strains) and 92.52%(136/147 strains), respectively. speA, speJ, speI, speH and speM had a low detection rate of 51.70%(76/147 strains), 49.66%(73/147 strains), 32.65%(48/147 strains), 23.81%(35/147 strains) and 4.08%(6/147 strains), respectively.No speK and speL were detected.The frequencies of speA and speJ in emm1.0 strains (65/76 strains, 85.53% and 64/76 strains, 84.21%) were significantly higher than those in emm12.0 strains (4/60 strains, 6.67% and 6/60 strains, 10.00%). However, the frequencies of speH and speI in emm1.0 strains (7/76 strains, 9.21% and 2/76 strains, 2.63%) were significantly lower than those in emm12.0 strains (28/60 strains, 46.67% and 45/60 strains, 75.00%) (all P<0.001). Conclusions:At present, emm1.0 and emm12.0 are the main GAS strains isolated from the throat of children with scarlet fever-like erythema in Beijing, and emm1.0 is more common.There is a correlation between emm genotyping and the superantigen gene profile.Type 1 superantigen gene profile is significantly more frequently detected in emm1.0 strains than in emm12.0 strains.Type 2, 3 and 4 superantigen gene profiles are significantly more frequently detected in emm12.0 strains than in emm1.0 strains.

Overview of the typing and clinical features of Group C Streptococcus and Group G Streptococcus / 中华实用儿科临床杂志

Group C Streptococcus (GCS) and Group G Streptococcus (GGS) distinctly differ from other Streptococcus in biochemical reactions, hemolytic properties, host species, and clinical characteristics.GCS and GGS are common colonizers of the skin, throat and female genitourinary tract of human body.The classification of GCS and GGS is complex and has been continuously corrected and revised over the past few decades.The outbreak of GCS and GGS infections mostly likely arises from environmental factors.GCS and GGS have similar pathogenicity, bacterial resistance characteristics, and clinical characteristics to group A Streptococcus.They can lead to various invasive infections, and Penicillin is still the first choice for their treatment currently.GCS and GGS infections are more severe than other Streptococcus infections.In this article, the classification and clinical characteristics of GCS and GGS were reviewed.
