ObjectiveTo explore the effect of core muscles training based on spinal fine-tuning manipulation on lumbar facet joint disorders. MethodsFrom February, 2021 to February, 2022, 80 patients with lumbar facet joint disorders in Huadong Hospital Affiliated to Fudan University were randomly divided into control group (n = 40) and observation group (n = 40) randomly. Both groups received routine treatment and spinal fine-tuning manipulation, while the observation group received core muscles training in addition, for six weeks. They were assessed with Japanese Orthopaedic Association (JOA) scores, Short-Form of McGill Pain Questionnaire and World Health Organization Quality of Life-BREF before and after treatment. The recurrence rate was observed after three months follow-up. ResultsThe scores of all the scales improved after treatment (t > 5.751, P < 0.001), and improved more in the observation group than in the control group (t > 2.051, P < 0.05). After three months follow-up, the recurrence rate was 7.89% (3/38) in the observation group, less than 28.13% (9/32) in the control group (χ² = 5.005, P = 0.025). ConclusionCombination of core muscles training may improve lumbar function, reduce lumbar pain, reduce recurrence and improve quality of life for patients with lumbar facet joint disorders.

Objective:To explore the application value of histogram and texture feature analysis based on CT images in distinguishing long bone osteosarcoma (OS) from Ewing sarcoma (ES).Methods:A retrospective collection of 25 patients with long bone osteosarcoma and 25 patients with Ewing sarcoma confirmed by surgery and pathology in National Cancer Center/National Clinical Research Center for Cancer/Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Qilu Hospital of Shandong University and Nanjing Drum Tower Hospital, Nanjing University Medical School, from March 2018 to May 2023 was conducted. All patients were randomly divided into a training set (21 cases of OS and 19 cases of ES) and a validation set (4 cases of OS and 6 cases of ES) in an 8∶2 ratio. The region of interest (ROI) on CT images to extract texture feature parameters was manually sketched. Random forest and least absolute shrinkage and selection operator (LASSO) algorithm were used for feature screening. Logistic regression (LR), random forest (RF), support vector machine (SVM) and K-nearest neighbor (KNN) classifiers were used to establish models respectively. Receiver operating characteristic (ROC)curve was drawn and area under the curve (AUC) was calculated to evaluate the diagnostic efficiency of the four models.Results:A total of 100 texture parameters were extracted from CT images, and 8 feature parameters (maximum 3D diameter, 10th percentile, kurtosis, maximum pixel intensity value, inverse normalization, grayscale level variance, long range high grayscale emphasis, and low grayscale area emphasis) were obtained through screening. Four classifiers were used to establish models, and the AUC values of the four models (LR, RF, SVM, KNN) in the validation group were 0.92, 0.79, 0.83, and 0.73, respectively. LR and SVM classifier algorithm trains models had high diagnostic efficiency, with an accuracy of 90%, sensitivity of 83%, specificity of 100%, and AUC of 92% for the LR classifier validation set; the accuracy of SVM classifier validation set was 80%, sensitivity was 67%, specificity was 100%, and AUC was 83%.Conclusions:LR and SVM models have high value in distinguishing OS and ES.

Objective:To evaluate the effect of workshop-based incontinence associated dermatitis (IAD) training course for geriatric nurse specialists, and to provide references and evidence for the application of workshop teaching model in specialized nursing training.Methods:The convenience sampling method was used to select 40 participants in the 9th Chongqing Geriatric Nurse Specialist Training Program in May 2021 as the intervention group, and IAD training was conducted using the workshop method. The 42 participants in the 8th Chongqing Geriatric Nurse Specialist Training Program in May 2020 were selected as the control group, who received IAD training through traditional teaching methods. After the training, the achievement of teaching objectives and teaching satisfaction were compared between the two groups using questionnaire survey, and IAD nursing knowledge and attitudes were compared using scales. SPSS 27.0 was used for the t-test and chi-square test. Results:The questionnaire survey showed that the intervention group achieved higher teaching objectives in all dimensions compared to the control group ( P<0.05). Compared with the control group, the intervention group had higher scores in teaching satisfaction regarding teaching format, interest in learning, practical skills, theoretical understanding, integration of theory and practice, and problem-solving abilities ( P<0.05). Compared with the control group, the intervention group demonstrated significantly higher scores in IAD nursing knowledge [(11.32±1.56) vs. (9.02±2.26), P<0.05] and attitudes [(37.63±3.54) vs. (32.81±2.97), P<0.05]. Conclusions:The workshop training has been highly recognized by the trainees, contributing to improved implementation effectiveness of teaching, enhancing the scores of IAD nursing knowledge and attitudes. This approach offers a new perspective for training with a practical focus in the specialized nursing field.

Recently, malaria incidence has sharply resurgence in the border area of northern Myanmar, with the parasite incidence rate in 2023 being 21.47 times (95% CI: 18.84-24.48) that of 2019 in Kachin State's Razan and nearby areas. This resurgence caused the number of imported malaria cases to increase from 188 in 2019 to 398 in 2023 in Yunnan Province. In addition to the impact of military conflict, the border malaria joint prevention and control cooperation mechanism and malaria control measures established between China and Myanmar have failed to be implemented effectively due to the impact of the international COVID-19 epidemic. Hence, it is recommended that relevant departments evaluate the quality and effectiveness of the current cross-border transmission measures for malaria in the China-Myanmar border area from a technical perspective, and provide a large demand for primaquine, which can block the spread of malaria and cure vivax malaria, in response to the current prevalent characteristics of vivax malaria predominating in northern Myanmar. Moreover, to effectively reduce the mortality of imported malaria patients and prevent re-importation and transmission, it is necessary to enhance clinical physicians' knowledge, awareness, and vigilance regarding malaria diagnosis and treatment in the Yunnan border region, as well as China's ability and quality of appropriate response to imported malaria.

ObjectiveTo construct a framework of PICO for occupational therapy to improve upper extremity function in stroke patients based on World Health Organization Family of International Classifications (WHO-FICs), and to analyze the functional outcome of major occupational therapies to improve upper extremity in stroke. MethodsUsing the WHO-FICs framework, the databases such as Web of Science, PubMed, CNKI and SinoMed were searched for literature related to occupational therapy interventions for upper extremity function in stroke patients from the date of establishment to October, 2022, and the contents of the literature were extracted for a systematic review. ResultsTen randomized controlled trials from six countries were finally included, involving 382 participants (≥ 18 years old). The literatures were mainly from the fields of rehabilitation medicine, physics and rehabilitation medicine, neuroscience, bioengineering medicine, occupational therapy and other research fields, and were published mainly after 2013. The quality of the included literatures was evaluated using Physiotherapy Evidence Database (PEDro) scale with a mean score of 7.5. Based on the WHO-FICs framework, the types of diseases included intracerebral haemorrhage (8B00), cerebral ischemic stroke (8B11), subarachnoid hemorrhage (8B01), abnormality of tonus and reflex (MB47), and hemiplegia (MB53). The main dysfunctions of the upper extremity after stroke included mobility of joint functions (b710), stability of joint functions (b715), muscle power functions (b730), muscle tone functions (b735), motor reflex functions (b750), control of voluntary movement functions (b760), involuntary movement functions (b765). Activity and participation included activity of upper limb, such as lifting and carrying objects (d430), hand and arm use (d445), and fine hand use (d440); and the daily life activities and social participation, such as self-care (d510-d570), domestic life (d610-d660), major life areas (d810-d879), community, social and civic life (d910-d950). Therapeutic interventions on body functions included electrical stimulation of muscle functions (MU2.SC.BP), assistance and guidance of exercise for involuntary movement reaction (MV2.PG.ZZ); therapeutic interventions involving activity and participation were training in lifting and carrying (SIA.PH.ZZ), training in fine hand use (SIG.PH.ZZ), exercises of arm and hand use (SIJ.PH.ZZ), self care (SM1-SMH), household tasks (SO2-SOD), and playing games (SXD.PH.ZZ); 15 to 60 minutes a time, three to ten times a week, for three to eight weeks, in hospital or at home. The outcomes of the intervention were divided into three levels. At the body function level, patients had improved neuromotor conduction function, reflex function, casual motor control, coordination and speed, joint mobility, and grip strength. At the activity and participation level, there were enhancements in upper limb mobility and speed, fine hand function and speed, frequency and quality of upper limb activity participation, and the capacities of daily living and reduced difficulty in daily activity tasks. In terms of whole functioning, patients had acquired quality of life and well-being and acquainted a feeling of pleasure and accomplishment. ConclusionA PICO framework was constructed for occupational therapy based on WHO-FICs. The health conditions included intracerebral haemorrhage, cerebral ischemic stroke, subarachnoid hemorrhage, abnormality of tonus and reflex, and hemiplegia. Upper extremity motor dysfunction mainly included dysfunction of voluntary motor control, low or hyperactive motor reflexes, abnormalities in muscle tone, impaired muscle coordination, poor stability of joint activities, and reduced muscle strength, etc. Activity limitation and participation restriction were manifested as functioning in the fields of arm and hand activity participation, fine manual activity, and activities of daily living and social participation. Therapeutic interventions at body function level included brain-computer interface-based functional electrical stimulation and unimanual mirror therapy; therapeutic interventions at activity and participation level included action observation training, bimanual mirror therapy, task-oriented training, bilateral arm training and upper extremity robotics training. The health and functional benefits included the improvements in upper extremity motor function, upper extremity mobility and participation levels, activities of daily living and social participation, and quality of life and well-being.

Objective To investigate the awareness of malaria-related knowledge, the use of mosquito nets and their influencing factors among residents in Banlao Township, Cangyuan County, Yunnan Province.. Methods In August 2020, 19 settlement sites in Banlao Township, Cangyuan County, Lincang City, Yunnan Province were selected as study areas, and permanent residents at ages of 10 years and older were enrolled for a questionnaire survey, including residents’ demographics, family economic status, malaria control knowledge and use of mosquito nets. In addition, the factors affecting the use of mosquito nets in the night prior to the survey were identified using multivariate logistic regression analysis. Results A total of 320 questionnaires were allocated, and all were recovered (a 100% recovery rate). There were 316 valid questionnaires, with an effective recovery rate of 98.75%. The 316 respondents included 152 men and 164 women and 250 Chinese respondents and 66 foreign respondents. The awareness of clinical syndromes of malaria was significantly higher among Chinese residents (71.60%) than among foreign residents (50.00%) (χ² = 11.03, P < 0.01), and the proportions of Chinese and foreign residents sleeping under mosquito nets were 46.00% and 69.70% on the night prior to the survey, respectively (χ² = 11.73, P < 0.01). Multivariate logistic regression analysis identified ethnicity group and type of residence as factors affecting the use of mosquito nets in the night prior to the survey. Conclusions The awareness of malaria control knowledge, the coverage and the use of mosquito nets were low among residents in Banlao Township, Cangyuan County, Yunnan Province. Targeted health education is recommended to improve the awareness of malaria control knowledge and self-protection ability. In addition, improving the allocation of long-lasting mosquito nets and health education pertaining to their uses and increasing the proportion of using mosquito nets correctly is needed to prevent re-establishment of imported malaria.

Abstract: Objective To compare the screening effects of RDT, microscopy and PCR for malaria among residents in low malaria areas and elimination areas, and to investigate the presence of malaria in residents of border Villages in Cangyuan Va County and asymptomatic infections in surrounding areas, providing a basis for preventing re-introduction of malaria after elimination. Methods From August 2020 to March 2021, the fingertip blood of the investigated subjects was collected from three survey sites in the border area between China and Myanmar, namely Banlao Township in Cangyuan Va Autonomous County of Lincang City, Banwai District, Mengmao County, the Second Special Zone of Shan State, Myanmar, Yongmo and Dayan Township, Nandeng Special Zone, the Second Special Zone of Shan State, Myanmar. The malaria parasite antigen detection test kit, malaria parasite microscopic examination, fluorescent quantitative PCR and nested PCR were used to detect the asymptomatic infection of malaria parasites. Results A total of 1 040 blood samples were collected, including 606 from China and 434 from Myanmar, with 506 males and 534 females. Among them, , there were 51 individuals aged 0 to <5 years, 283 aged 5 to < years, 187 aged 15 to < years, 232 aged 30 to <45 years, 205 aged 45 to < years, and 82 aged ≥60 years. All 1 040 people tested negative for plasmodium antigen detection kit. One case of Plasmodium vivax detected by plasmodium microscopic etiology, with a detection rate of 0.10%. One case of P. vivax was also detected by fluorescent quantitative PCR and nested PCR, with a detection rate of 0.10%. Among them, one case of P. vivax was detected in Banwai District, Mengmao County, the Second Special Zone of Shan State, Myanmar, with a detection rate of 0.35%. The detection rates of malaria parasites in Banlao Township in Cangyuan Va Autonomous County of Lincang City, Yunnan Province and Yongmo Township and Dayan Township, Nandeng Special District, the Second Special Zone of Shan State, Myanmar were both 0. The difference in the detection rate of malaria parasites among the three survey sites was not statistically significant (χ2 =2.682, P>0.05). The asymptomatic P. vivax infection was detected in a 6-year-old girl from Banwai District, Mengmao County, the Second Special Zone of Shan State, Myanmar. Conclusions RDT is not suitable for malaria screening in low malaria area and elimination area. Microscopic examination and PCR can be used for malaria screening, but PCR operation is complex and costly. In surrounding areas outside of China, malaria is still prevalent, while there is no source of malaria infection in border villages of Cangyuan Va County. However, there is a risk of importation, and timely and effective measures should be taken to prevent reintroduction and transmission.

Among them, 11 cases were sports injury and trauma (29.5%), 11 cases were heat stroke and other related symptoms (25%), 6 cases were sunburn (13.6%), 10 cases were oral diseases of five senses (22.8%), 4 cases were upper respiratory tract infection (9.1%).Conclusions:The holding of large-scale outdoor events in summer should focus on heat-related diseases, and it is necessary to effectively do the corresponding planning work in advance in terms of reasonable allocation of medical resources and targeted training of professionals.

Objective:To investigate the effect of conventional treatment plus long-term transcranial direct current stimulation (tDCS) on consciousness recovery in patients with minimally conscious state (MCS) after traumatic brain injury (TBI).Methods:A retrospective cohort study was conducted to analyze the clinical data of 60 patients with MCS after TBI admitted to Zhejiang Armed Police Corps Hospital from January 2019 to December 2020, including 38 males and 22 females, aged 19-60 years [(45.7±11.4)years]. Course of disease was 3-6 months [(4.6±0.9)months]. Of all, 30 patients received internal medicine, hyperbaric oxygen, rehabilitation and other conventional treatment (conventional treatment group), and 30 patients received tDCS stimulation on the basis of conventional treatment (tDCS treatment group). The tDCS stimulation contained 4 cycles for 28 days with each cycle lasting for 7 days (stimulation for 5 days, rest for 2 days). Coma recovery scale-revised (CRS-R) total score, brainstem auditory evoked potential (BAEP) score and clinical effictive rate (significantly effective+effective) were compared between the two groups before treatment, during 4 cycles of treatment and at 6 months and 12 months after treatment. Complications induced by tDCS were also evaluated.Results:There was no significant difference in CRS-R total score and BAEP score between the two groups before treatment (all P>0.05). CRS-R total score and BAEP score in tDCS treatment group were significantly higher than those in conventional treatment group during 4 cycles of treatment and at 6 months and 12 months after treatment (all P<0.05). CRS-R total score and BAEP score in both groups gradually increased during 4 cycles of treatment and at 6 months and 12 months after treatment (all P<0.05). The clinical effective rate in tDCS treatment group was 73% (22/30) when compared to 57% (17/30) in conventional treatment group ( P<0.05). In tDCS treatment group, 10 patients had local reversible slight redness at the cathodal position, while no other serious adverse effects, such as local burns, ulceration, exudation or epilepsy. Conclusion:Compared with conventional treatment, conventional treatment plus long-term tDCS can be more effective in improving the state of consciousness without serious adverse effects for MCS patients after TBI.
