Objective To provide reference for the subsequent clinical application of WBV,based on the impacts of whole body vibration(WBV)with different frequencies on gross motor function and walking function in children with dyskinetic cerebral palsy.Methods 60 children aged 6～12 with dyskinetic cerebral palsy,who had been treated at the department of rehabilitation medicine in the Affiliated Southwest Medical University from October 2021 to November 2022,were selected.They were randomly divided into a control group(n = 20),(25±5)Hz group(n = 20),and(35±5)Hz group(n = 20).All the three groups received conventional rehabilitation,while the(25±5)Hz group received additional WBV with(25±5)Hz and the(35±5)Hz group received WBV with(35±5)Hz.They were treated for eight weeks.The scores on D and E domains of GMFM-88,TUGT,the score on Berg Balance Scale,and footprint analysis were used for assessment of the efficacy after treatment.Results As compared with the baselines,the scores were improved in the three groups after treatment(P＜0.001).BBS(F = 12.502),TUGT(F = 8.211),scores on D and E domains of GMFM-88(F = 12.802 and 8.505),stride length(F = 12.279),1MWT distance(F = 12.619),and step width(F = 13.582)were better in the(35±5)Hz group than in the(25±5)Hz group and the control group(P＜0.05 and P＜0.01);and the efficacy was better in the(25±5)Hz group than in the control group,the difference was statistically significant(P＜0.05 and P＜0.01).Conclusion WBV can improve trunk control,lower limb gross motor function,and walking function in children with involuntary motor type cerebral palsy.(35±5)Hz is better than(25±5)Hz for the efficacy of WBV.

Objective To investigate the internal and external factors of scientific and technological innovations in pro-vincial maternal and child health care institutions and propose effective strategies for facilitating the innovations.Methods The PEST-SWOT model was used to analyze the internal strengths and weaknesses,external opportunities,and threats of the scientific and technological innovations in a provincial maternal and child health care institution from the perspectives of political,econom-ic,social,and technical environment.Results The institution has advantages and opportunities in policy support,scientific re-search management and investment,and disciplinary characteristics.However,it faces some threats and has disadvantages in tal-ent team,information-oriented level,and industrial competition.Conclusion The development of scientific and technological in-novation in provincial maternal and child health care institutions is affected by internal and external factors.It is necessary to firmly seize opportunities and comprehensively promote scientific and technological innovations from the aspects of medical treat-ment,teaching and research collaboration,discipline layout,talent team,and information-oriented construction.

Objective To explore the current research situation,hotspots and development trend in the field of acupuncture and mox-ibustion intervention for post-stroke dysphagia(PSD). Methods The literature on acupuncture and moxibustion intervention for PSD was retrieved from CNKI,VIP and Wan-fang database from 1994 to December 31st,2023,and analyzed with VOSviewer and CiteSpace. Results A total of 1 816 articles were included,and the number of publications increased year by year,reaching a peak in 2021 with 180 articles.There were 274 core authors included in the literature,among which Cheng Hongliang,Zhou Hongfei and Feng Weixing were the authors with the highest publication volume.The First Affiliated Hos-pital of Tianjin University of Chinese Medicine was the most productive institution,and the connections between institutions were relatively scattered.The high-frequency keywords were swallowing dysfunction,stroke,acu-puncture and moxibustion therapy,as well as rehabilitation therapy,among which tongue triple acupuncture,elec-troacupuncture,nape acupuncture and scalp acupuncture were the most commonly used methods.In addition,acupuncture combined with rehabilitation training,electrical stimulation,or other methods for PSD and acupoint selection rules were also research hotspots.When evaluating the efficacy of acupuncture intervention for PSD,the focus gradually shifted from the effective rate to the use of videofluorographic swallowing study,water swal-lowing test,standardized swallowing assessment,surface electromyography and other indicators to evaluate the swallowing function and the severity of dysphagia. Conclusion Research on acupuncture and moxibustion interventions for PSD has developed rapidly,with hotspots in-cluding the selection of specific acupuncture and moxibustion techniques,the combination of acupuncture and moxibustion with other rehabilitation therapies,outcome indicators for acupuncture and moxibustion interven-tions in PSD,and the rules of acupoint selection.In the future,it is essential to strengthen academic exchanges and collaborations across institutions and regions.Greater emphasis should be placed on objective evaluation in-dicators of acupuncture and moxibustion therapies for improving the swallowing function in PSD patients,as well as on optimizing combinations of acupuncture and moxibustion with modern rehabilitation approaches,so as to better guide clinical practice.

Objective:To report a case of Kufor-Rakeb syndrome caused by novel ATP13A2 mutation, collect the cases related to ATP13A2 gene mutation published in recent years, summarize the clinical manifestations of the disease, and broaden the clinical diagnostic thinking. Methods:The clinical manifestations of a newly diagnosed patient with Kufor-Rakeb syndrome caused by ATP13A2 gene mutation admitted to Zhongda Hospital, Southeast University on November 26, 2021, were summarized. The related cases of ATP13A2 mutation published from January 2000 to December 2021 were searched through the PubMed and CNKI databases using the keywords "ATP13A2" and "Parkinson′s disease". The onset age, clinical symptoms, family history, genetic testing, and levodopa responsiveness results of the patients were collected. Results:The patient is a 52-year-old female with the main clinical symptoms of static tremor and bradykinesia. Physical examination showed a gear like increase in muscle tension in the right upper limb, involuntary shaking of the right hand and slow movement. She had good responsiveness to levodopa, and the magnetic resonance imaging and susceptibility weighted imaging of the head showed a lack of clear observation of bilateral black matter swallowtail sign. Whole exome sequencing showed that mutations c.3010A>G (p.S1004G) and c.1195+5G>A (splice) were found in the ATP13A2 gene, both of which were not reported. The c.3010A>G (p.S1004G) mutation originated from the mother, and the c.1195+5G>A (splice) mutation originated from the father. In the retrospective literature review, a total of 10 cases were collected, with onset ages ranging from 18 months to 24 years. Among them, 4/10 patients′ parents married close relatives, and the clinical manifestations were mainly motor symptoms of Parkinson′s disease. In addition, 5/10 patients had cognitive dysfunction, and 3/10 patients had mental symptoms. And demonstrations of most patients′ magnetic resonance imaging were normal in the early stage of the disease, and as the disease progressed, some patients′ imaging results showed specific changes, such as whole brain atrophy and changes in the corpus callosum. Meanwhile, 8/10 patients showed good responsiveness to levodopa. Conclusions:Kufor-Rakeb syndrome is a special type of adolescent levodopa responsive Parkinson′s disease caused by ATP13A2 mutation, which is an autosomal recessive disorder. In addition to motor symptoms such as static tremor and bradykinesia, its clinical manifestations may also be accompanied by non motor symptoms such as cognitive and psychiatric disorders. The disease responds well to treatment with levodopa.

Objective To examine the compliance of and factors affecting target attainment of serum trough concentration of norvancomycin in ICU patients,and the effects of different trough concentrations on clinical efficacy and renal impairment.Methods Adult patients admitted to the Department of Critical Care Medicine of Huangshan People's Hospital and receiving intravenous infusion of norvancomycin from January 2020 to December 2022 were included.The dosing regimens and steady-state trough concentrations of norvancomycin were analyzed.The clinical efficacy and renal impairment were compared between different trough concentration levels.The compliance of trough concentration in critically ill patients with different renal functions was examined.Logistic regression analysis was performed to profile the factors possibly affecting the trough concentration of norvancomycin.Results A total of 97 patients were included.The target serum trough concentration(10-20 mg/L)was reached in only 33.0％(32/97)of the critically ill patients.The serum trough concentration was below the target in 51.5％(50/97)of the patients,above the target in 15.5％of the patients.The clinical cure rate and incidence of renal impairment were significantly different among the three groups of patients with different trough concentrations(P＜0.05).The compliance with target serum trough concentration varied with different renal function tests(P＜0.05).Augmented renal clearance and normal renal function were associated with trough concentrations lower than the target.As renal dysfunction got worse,serum trough concentration was more probably higher than the target(P＜0.05).Univariate analysis showed that daily dose,age,gender,height,weight,body mass index(BMI),APACHE Ⅱ score,sequential organ failure assessment(SOFA)score,blood creatinine,urea nitrogen,procalcitonin,concomitant septic shock,and use of norepinephrine were significantly correlated with trough concentrations of norvancomycin(P＜0.05).Multivariate logistic regression analysis indicated that age,SOFA score,blood urea nitrogen,gender,and norepinephrine use were independent factors affecting the serum trough concentration of norvancomycin(P＜0.05).Conclusions The serum trough concentration of norvancomycin varied with renal function states in ICU patients.It is difficult to achieve the steady-state target trough concentration(10-20 mg/L).The clinical cure rate is lower when the trough concentration is lower than the target.As the trough concentration increases,the incidence of renal impairment increases.Age,SOFA score,urea nitrogen,gender,and norepinephrine use are independent factors affecting the serum trough concentrations of norvancomycin.

Objective To investigate the safety and clinical effect of prophylactic ileostomy using right lower abdominal specimen extraction incision in laparoscopic rectal low anterior resection and its impact on ileos-tomy closure.Methods A retrospective analysis was conducted on 127 patients who underwent laparoscopic low anterior resection of rectal cancer combined with prophylactic ileostomy in Department of General Surgery in our hospital from January 2020 to December 2023.Patients were divided into observation group(n=60)and control group(n=67)based on whether with prophylactic ileostomy using the right lower abdominal specimen extraction incision or not.Relevant data and clinical data of ileostomy closure were compared between the two groups.Results(1)There was no significant difference in baseline clinical data between the two groups(P>0.05).(2)In terms of operation time,pain score within three days after surgery and postoperative first exhaust time,the observation group was better than the control group,showing statistical difference(P<0.05).In the observation group,the average length of the incision was longer than that in the control group,and it was significantly different between the two groups(P<0.05).There was no significant difference between the two groups in terms of blood loss,post-operative feeding time and postoperative hospital stay(P>0.05).(3)There was no significant difference between the two groups in postoperative and ostomy-related complication S(P>0.05).(4)The observation group was better than the control group in terms of postoperative pain score and postoperative first exhaust time,indicating statistical significance(P<0.05).There were no significant differences in surgical time,abdominal adhesion,blood loss,postoperative hospital stay and postoperative complications between the two groups(P>0.05).Conclusion The patients undergoing laparoscopic rectal low anterior resection who needs prophylactic ileostomy using right lower abdominal specimen extraction incision can improve the appearance of the incision,shorten operation time,reduce postoperative pain of the patients but does not increase postoperative complications and the difficulty of ileostomy closure.It is safe and feasible,which worthy for clinical promotion.

ObjectiveTo observe the lower limb muscle activation strategy of healthy middle-aged and old women during stair ascent and descent with surface electromyography. MethodsFrom August, 2021 to February, 2022, 20 healthy middle-aged and old women were measured the surface electromyography root mean square (RMS) and integrated electromyography (iEMG) of bilateral vastus lateral, rectus femoris, vastus medialis, biceps femoris and semitendinosus during stair ascent and descent, and co-contraction ratio was calculated. ResultsDuring stair ascent, the RMS of bilateral vastus lateral, rectus femoris and vastus medialis was higher at starting stage than at following stage (|t| > 6.650, P < 0.001), while the RMS of biceps femoris and semitendinosus was lower (t > 3.559, P < 0.01); and the co-contraction ratio of hamstrings/quadriceps was lower at starting stage than at following stage (t > 8.185, P < 0.001). During stair descent, the RMS of bilateral vastus lateral, vastus medialis, biceps femoris and semitendinosus was higher at following stage than at starting stage (t > 2.345, P < 0.05), as well as the co-contraction ratio of hamstrings/quadriceps (t > 2.405, P < 0.05). ConclusionThe activities of the muscles around the knees are almost symmetrical during stair ascent and descent for healthy middle-aged and old women. The activation and co-contraction ratio of quadriceps and hamstring are various at starting/following stages.

ObjectiveTo observe the effect of interlimb-coordinated training on pulmonary function in patients with early primary Parkinson's disease. MethodsFrom February, 2021 to February, 2022, 60 patients with primary Parkinson's disease in Affiliated Hospital of Southwest Medical University were divided into control group (n = 30) and experimental group (n = 30) according to the management, who accepted medicine and medicine combined with interlimb-coordinated training, for twelve weeks, respectively. Before and after treatment, the forced expiratory volume in the first second (FEV₁), forced vital capacity (FVC), maximum expiratory flow (PEF) and vital capacity (VC) were measured with pulmonary function instrument, while the peak oxygen uptake (VO_2peak), anaerobic threshold (AT) and peak power (WR_peak) were measured with Cardiopulmonary Exercise Test (CPET), and the maximum inspiratory pressure (MIP) and maximum expiratory pressure (MEP) were measured with respiratory driving instrument. ResultsAfter treatment, FEV₁, FVC, PEF, VC, VO_2peak, AT, WR_peak, MIP and MEP increased in the experimental group (t > 2.087, P < 0.05), and they were more in the experimental group than in the control group (t > 2.079, P < 0.05). ConclusionInterlimb-coordinated training could improve the pulmonary function, aerobic exercise ability and respiratory muscle strength of patients with early primary Parkinson's disease.

ObjectiveTo systematically evaluate the effects of threshold inspiratory muscle training (TIMT) on respiratory function, motor function and quality of life in patients with chronic obstructive pulmonary disease (COPD). MethodsRandomized controlled trials (RCT) about the effects of TIMT on dyspnea, quality of life, motor function and inspiratory muscle strength for COPD patients were retrieved from PubMed, EBSCO, Web of Science, Ovid, Cochrane Library, SinoMed, CNKI, VIP, since establishment to September, 2020. Two researchers independently screened literatures, extracted data and evaluated the methodological quality. A meta-analysis was performed using RevMan 5.3. ResultsA total of 30 RCTs involving 2 060 patients were included. TIMT could obviously improve the maximum inspiratory pressure (MD = 10.68, 95%CI 7.43 to 13.92, P < 0.001), optimize the results of 6-minute Walking Test (MD = 24.62, 95%CI 9.09 to 40.15, P = 0.002), the St George's Respiratory Questionnaire (MD = -3.08, 95%CI -5.84 to -0.33, P = 0.03), the modified Medical Research Council Dyspnea Scale (MD = -0.30, 95%CI -0.52 to -0.07, P = 0.01) and Borg score (MD = -0.84, 95%CI -1.24 to -0.44, P < 0.001). TIMT could also improve the forced expiratory volume in one second (MD = 0.11, 95%CI 0.04 to 0.19, P = 0.003) and the forced expiratory volume in one second in predicted (MD = 3.72, 95%CI 2.62 to 4.82, P < 0.001). There was no significant difference in the COPD Assessment Test (MD = -1.14, 95%CI -2.32 to 0.03, P = 0.06) or forced vital capacity (MD = 0.07, 95%CI -0.12 to 0.25, P = 0.49). ConclusionTIMT can improve the inspiratory muscle strength, alleviate the symptoms of dyspnea, and improve the lung function and the quality of life for COPD patients.

Retinal pigment epithelial (RPE) is primarily impaired in age-related macular degeneration (AMD), leading to progressive loss of photoreceptors and sometimes choroidal neovascularization (CNV). mTOR has been proposed as a promising therapeutic target, while the usage of its specific inhibitor, rapamycin, was greatly limited. To mediate the mTOR pathway in the retina by a noninvasive approach, we developed novel biomimetic nanocomplexes where rapamycin-loaded nanoparticles were coated with cell membrane derived from macrophages (termed as MRaNPs). Taking advantage of the macrophage-inherited property, intravenous injection of MRaNPs exhibited significantly enhanced accumulation in the CNV lesions, thereby increasing the local concentration of rapamycin. Consequently, MRaNPs effectively downregulated the mTOR pathway and attenuate angiogenesis in the eye. Particularly, MRaNPs also efficiently activated autophagy in the RPE, which was acknowledged to rescue RPE in response to deleterious stimuli. Overall, we design and prepare macrophage-disguised rapamycin nanocarriers and demonstrate the therapeutic advantages of employing biomimetic cell membrane materials for treatment of AMD.
