Chinese multidisciplinary expert consensus on the management of adverse drug reactions associated with savolitinib / 中华肿瘤杂志

MET gene is a proto-oncogene, which encodes MET protein with tyrosine kinase activity. After binding to its ligand, hepatocyte growth factor, MET protein can induce MET dimerization and activate downstream signaling pathways, which plays a crucial role in tumor formation and metastasis. Savolitinib, as a specific tyrosine kinase inhibitor (TKI) targeting MET, selectively inhibits the phosphorylation of MET kinase with a significant inhibitory effect on tumors with MET abnormalities. Based on its significant efficacy shown in the registration studies, savolitinib was approved for marketing in China on June 22, 2021 for the treatment of advanced non-small cell lung cancer with MET 14 exon skipping mutations. In addition, many studies have shown that MET TKIs are equally effective in patients with advanced solid tumors with MET gene amplification or MET protein overexpression, and relevant registration clinical studies are ongoing. The most common adverse reactions during treatment with savolitinib include nausea, vomiting, peripheral edema, pyrexia, and hepatotoxicity. Based on two rounds of extensive nationwide investigations to guide clinicians, the consensus is compiled to use savolitinib rationally, prevent and treat various adverse reactions scientifically, and improve the clinical benefits and quality of life of patients. This consensus was prepared under the guidance of multidisciplinary experts, especially including the whole-process participation and valuable suggestions of experts in Traditional Chinese Medicine, thus reflecting the clinical treatment concept of integrated Chinese and western medicines.

Chinese expert consensus on the diagnosis and treatment of osteoporotic periarticular fracture of the shoulder in the elderly (version 2023) / 中华创伤杂志

Periarticular fracture of the shoulder is a common type of fractures in the elderly. Postoperative adverse events such as internal fixation failure, humeral head ischemic necrosis and upper limb dysfunction occur frequently, which seriously endangers the exercise and health of the elderly. Compared with the fracture with normal bone mass, the osteoporotic periarticular fracture of the shoulder is complicated with slow healing and poor rehabilitation, so the clinical management becomes more difficult. At present, there is no targeted guideline or consensus for this type of fracture in China. In such context, experts from Youth Osteoporosis Group of Chinese Orthopedic Association, Orthopedic Expert Committee of Geriatrics Branch of Chinese Association of Gerontology and Geriatrics, Osteoporosis Group of Youth Committee of Chinese Association of Orthopedic Surgeons and Osteoporosis Committee of Shanghai Association of Chinese Integrative Medicine developed the Chinese expert consensus on the diagnosis and treatment of osteoporotic periarticular fracture of the shoulder in the elderly ( version 2023). Nine recommendations were put forward from the aspects of diagnosis, treatment strategies and rehabilitation of osteoporotic periarticular fracture of the shoulder, hoping to promote the standardized, systematic and personalized diagnosis and treatment concept and improve functional outcomes and quality of life in elderly patients with osteoporotic periarticular fracture of the shoulder.

A Novel EYA1 Mutation Causing Alternative RNA Splicing in a Chinese Family With Branchio-Oto Syndrome: Implications for Molecular Diagnosis and Clinical Application

Objectives@#. Branchio-oto syndrome (BOS) primarily manifests as hearing loss, preauricular pits, and branchial defects. EYA1 is the most common pathogenic gene, and splicing mutations account for a substantial proportion of cases. However, few studies have addressed the structural changes in the protein caused by splicing mutations and potential pathogenic factors, and several studies have shown that middle-ear surgery has limited effectiveness in improving hearing in these patients. BOS has also been relatively infrequently reported in the Chinese population. This study explored the genetic etiology in the family of a proband with BOS and provided clinical treatment to improve the patient’s hearing. @*Methods@#. We collected detailed clinical features and peripheral blood samples from the patients and unaffected individuals within the family. Pathogenic mutations were identified by whole-exome sequencing and cosegregation analysis and classified according to the American College of Medical Genetics and Genomics guidelines. Alternative splicing was verified through a minigene assay. The predicted three-dimensional protein structure and biochemical experiments were used to investigate the pathogenicity of the mutation. The proband underwent middle-ear surgery and was followed up at 1 month and 6 months postoperatively to monitor auditory improvement. @*Results@#. A novel heterozygous EYA1 splicing variant (c.1050+4 A>C) was identified and classified as pathogenic (PVS1(RNA), PM2, PP1). Skipping of exon 11 of the EYA1 pre-mRNA was confirmed using a minigene assay. This mutation may impair EYA1-SIX1 interactions, as shown by an immunoprecipitation assay. The EYA1-Mut protein exhibited cellular mislocalization and decreased protein expression in cytological experiments. Middle-ear surgery significantly improved hearing loss caused by bone-conduction abnormalities in the proband. @*Conclusion@#. We reported a novel splicing variant of EYA1 in a Chinese family with BOS and revealed the potential molecular pathogenic mechanism. The significant hearing improvement observed in the proband after middle-ear surgery provides a reference for auditory rehabilitation in similar patients.

The effect of abdominal visceral fat area on perioperative complications and pancreatic fistula in primary gastric carcinoma patients after laparoscopic assisted radical gastrectomy / 中华普通外科杂志

Objective:To study the effect of visceral fat area (VFA) on postoperative complications and pancreatic fistula in patients undergoing laparoscopic assisted radical gastrectomy for gastric careinoma.Methods:Clnical data of 214 primary gastric cancer patients undergoing laparoscopic assisted radical gastrectomy between Jan 2017 and Jan 2022 at the Department of General Surgery, Shouguang People's Hospital were retrospectively reviewed.Results:There were 85 patients in high VFA group and 129 patients in the low VFA group. The body mass index (25.1±3.4) kg/m 2 and visceral fat area (143.4±41.1) cm 2 in the high VFA group were higher than those in the low VFA group (21.2±2.9) kg/m 2 and visceral fat area (58.7±31.9) cm 2. The operative time was (228.3±53.1) min vs. (206.3±62.9) min ( t=5.538, P=0.017). The intraoperative blood loss was (264.6±173.6) ml vs. (213.9±156.2) ml ( t=3.373, P=0.035). The postoperative hospital stay was (12.5±4.0) d vs. (10.3±3.7) d ( t=7.781, P=0.013). Twenty-three cases developed postoperative complications in the high VFA group vs. 20 cases in the low VFA group ( χ2=4.261, P=0.039). Patients in the high VFA group had an incidence of clinically relevant pancreatic fistula of 10.6% vs. 3.1% in patients in the low VFA group ( χ2=5.034, P=0.038). Univariate and multivariate analysis of clinically relevant pancreatic fistulas in patients with different VFA groups showed that men ≥134.6 cm 2 and women ≥91.1 cm 2 with VFA and operative time ≥250 min were independent risk factors for the occurence of clinically relevant pancreatic fistulas after laparoscopic assisted radical gastrectomy. Conclusions:VFA increases the difficulty of laparoscopic-assisted radical gastrectomy, resulting in increased postoperative complications. VFA and operation time are independent risk factors for clinically relevant pancreatic fistula after radical gastrectomy for gastric cancer.

Characteristics and management mechanism of imported malaria from overseas during the malaria elimination phase in Wuhan City / 公共卫生与预防医学

Objective To analyze the characteristics of imported malaria epidemic from overseas in Wuhan, to explore the management mechanism of on-site cases, and to accumulate experience for the treatment of imported malaria in large cities after malaria elimination. Methods The epidemiological data on imported malaria from abroad during the period of malaria elimination (2010-2019) in Wuhan were collected. The gender, age and severe illness-related factors of the cases were analyzed. Based on the characteristics of the epidemic and the current situation of prevention and control, the content and experience of the “Municipal-District 24-7” case mechanism were discussed. Results The medical resources in Wuhan were the best in the central region, resulting in a large number of imported malaria cases, with a total of 474 cases reported from 2010 to 2019 (40.79% of the total number of cases in Hubei Province), including 359 cases of falciparum malaria, 36 severe cases and one death (the death rate was 0.28%). The patients were mainly young and middle-aged men aged 20 to 49 years old (97.26%). There were many referral cases (40.30%), and there was no seasonal clustering of cases reported. The undiagnosed proportion at the first visit was 44.85%, and the time of attack-diagnosis was 4 days or more in 61.00% of cases. The occurrence of severe cases was related to unconfirmed diagnosis at the first visit (χ2=35.46, P<0.001) and attack-diagnosis time (Z=-6.49, P<0.001). Conclusion Imported malaria occurs frequently in Wuhan, mainly falciparum malaria. However, “Municipal-District 24-7” case mechanism has effectively curbed the occurrence of severe and death cases and provided valuable experience for case management in similar cities in China.

Genetic research progress in branchio-oto syndrome/ branchio-oto-renal syndrome / 中南大学学报(医学版)

Branchio-oto syndrome (BOS)/branchio-oto-renal syndrome (BORS) is a kind of autosomal dominant heterogeneous disorder. These diseases are mainly characterized by hearing impairment and abnormal phenotype of ears, accompanied by renal malformation and branchial cleft anomalies including cyst or fistula, with an incidence of 1/40 000 in human population. Otic anormalies are one of the most obvious clinical manifestations of BOS/BORS, including deformities of external, middle, inner ears and hearing loss with conductive, sensorineural or mix, ranging from mild to profound loss. Temporal bone imaging could assist in the diagnosis of middle ear and inner ear malformations for clinicians. Multiple methods including direct sequencing combined with next generation sequencing (NGS), multiplex ligation-dependent probe amplification (MLPA), or array-based comparative genomic hybridization (aCGH) can effectively screen and identify pathogenic genes and/or variation types of BOS/BORS. About 40% of patients with BOS/BORS carry aberrations of EYA1 gene which is the most important cause of BOS/BORS. A total of 240 kinds of pathogenic variations of EYA1 have been reported in different populations so far, including frameshift, nonsense, missense, aberrant splicing, deletion and complex rearrangements. Human Endogenous Retroviral sequences (HERVs) may play an important role in mediating EYA1 chromosomal fragment deletion mutations caused by non-allelic homologous recombination. EYA1 encodes a phosphatase-transactivator cooperated with transcription factors of SIX1, participates in cranial sensory neurogenesis and development of branchial arch-derived organs, then regulates the morphological and functional differentiation of the outer ear, middle ear and inner ear toward normal tissues. In addition, pathogenic mutations of SIX1 and SIX5 genes can also cause BOS/BORS. Variations of these genes mentioned above may cause disease by destroying the bindings between SIX1-EYA1, SIX5-EYA1 or SIX1-DNA. However, the role of SIX5 gene in the pathogenesis of BORS needs further verification.

Clinical characteristics and comprehensive treatment of patients with cleidocranial dysplasia / 中华口腔医学杂志

Objective: To summarize the clinical characteristics of patients with cleidocranial dysplasia (CCD) and analyze their treatment methods. Methods: From January 2000 to December 2020, patients with CCD who completed comprehensive treatment in the Department of Orthodontics and the First Dental Clinic, School and Hospital of Stomatology, China Medical University were retrospectively analyzed. A total of 14 CCD patients [7 males and 7 females, aged (16.1±4.5) years] were collected. There were 153 impacted permanent teeth in this study. In addition to the teeth that needed to be extracted due to special conditions, 147 impacted teeth were pulled into the dentition using closed traction. Patients were divided into adolescent group (≥12 years and<18 years, 10 patients) and adult group (≥18 years, 4 patients). Failure rate of traction was compared between the two groups. Factors affecting the success rate of closed traction such as vertical position of teeth (high, middle and low) and horizontal position of the teeth (palatal, median and buccal) were analyzed. Results: The incidence of maxillary impacted teeth [69.3% (97/140)] was higher than that of mandibular impacted teeth [40% (56/140)]. The difference was statistically significant (χ2=24.22, P<0.001). The supernumerary teeth were mainly located in the premolar area 61.4% (21/44), and most of them were in the palatal region of the permanent teeth 95.5% (42/44). They were generally located at the same height or the occlusal side of the corresponding permanent teeth. The success rate of closed traction was 93.9% (138/147). The success rate in the adolescent group [98.2% (108/110)] was higher than that in the adult group [81.1% (30/37)], and the difference was significant (χ2=14.09, P<0.05). Failure after closed traction of 9 teeth was found totally, including 7 second premolars. The success rate of traction in impacted second premolars at different vertical (χ2=11.44, P<0.05) and horizontal (χ2=9.71, P<0.05) positions in alveolar bone was different significantlly. The success rates of the second premolars were high (15/16), middle (12/13), low (2/7), and lingual palatine (10/17), median (19/19), lip-buccal (0/0), respectively. Conclusions: The closed traction of impacted teeth in patients with CCD was effective, and the age was the main variable affecting the outcome. The success rate of traction in impacted second premolars located in low position vertically or in palatal position was low, which required close observation during treatment.

Objective: To investigate the imaging features of condylar cystic degeneration of temporomandibular joint (TMJ) by cone-beam CT (CBCT), spiral CT, MRI and radionuclide bone imaging. Methods: From January 2018 to December 2020, thirty-two patients with cyst-like lesions of condylein temporomandibular joint were examined by CBCT, spiral CT, MRI and radionuclide bone imaging at the Department of Oral and Maxillofacial Surgery in General Hospital of Chinese PLA. There were 12 males and 20 females involved, aged from 16 to 65 years with an average age of (33.9±12.5) years. The characteristics of CBCT, spiral CT, MRI and radionuclide bone imaging were analyzed. Condylar cyst like lesions were classified as type A and type B based on the presence or absence of surface bone defects. Condylar cyst like lesions were classified as type Ⅰ(yes) and type Ⅱ(no) according to the accompanying bone marrow edema-like lesions of the condyles. The incidence of condylar bone marrow edema, disc displacement and abnormal bone metabolism were analyzed. Results: A total of 64 joint images of 32 patients were included, including 34 sides with TMJ cyst-like lesion and 6 sides with multiple cyst-like lesions,the total cyst-like lesions were 42. The largest diameter of cyst-like lesion ranged from 1.0 to 12.4 mm, with an average length of (3.7±1.8) mm. There were 24 cases of type A TMJ cyst like lesion and 10 cases of type B cyst-like lesion. The detection rate of CBCT was 95.2% (40/42) and that of spiral CT was 100% (42/42), there was no significant difference (Calibration Chi-square=0.51, P=0.474). The detection rate of nuclear magnetic resonance was 80.1% (34/42), and the detection rate of cyst-like lesions less than 2 mm was 3/11. In the cyst like lesion side, there were 9 sides with anterior disc displacement with reduction, 20 sides with anterior disc displacement without reduction. In the non-cyst like lesion side, 10 sides with anterior disc displacement with reduction and 6 sides with anterior disc displacement without reduction. There was a significant difference in the displacement of the disc between cyst-like and non-cystic lesion side (χ²=7.80, P=0.005). MRI showed that 6 cases of cystic side[17.6% (6/34)] had bone marrow edema-like lesions (all type A), 1 case of non-cyst like lesions side [3.3% (1/30)]had bone marrow edema-like lesion, there was no significant difference between cystic and non-cystic lesions (Calibration Chi-square=2.04, P=0.153). There was a significant difference between type A and B cystic lesions (Fisher exact probability method, P= 0.024). Radionuclide bone imaging showed abnormal bone metabolism in 26 patients in the cyst-like lesion side and 5 patients in the non-cyst like lesion side (χ²=22.82, P<0.001). Conclusions Multi-slice Spiral CT could detect the cyst-like lesion of TMJ condyle in the early stage, which is different from the large joint. And the formation mechanism may vary from the different classifications.

Accuracy analysis of amylase, C-reactive protein and procalcitonin in abdominal cavity of postoperative gastric cancer in predicting the occurrence of clinically related pancreatic fistula / 国际外科学杂志

Objective:To evaluate the relationship between abdominal amylase, C-reactive protein (CRP), procalcitonin (PCT) and clinically relevant pancreatic fistula in the early stage after radical gastrectomy for gastric cancer, and to explore whether they can be used as early predictors of pancreatic fistula and their accuracy, in order to help identify pancreatic fistula in the early stage after gastrectomy.Methods:The clinical data of 372 patients diagnosed as gastric cancer and underwent gastrectomy in Shouguang People′s Hospital from January 2017 to December 2021 were retrospectively analyzed, including 190 males and 182 femals, aged from 28 to 32 years old, with the average years of 63.5±10.6. The receiver operating characteristic (ROC) curves of abdominal amylase on the first day and serum CRP and procalcitonin on the third day after surgery for gastric cancer were analyzed. The ROC curve was used to determine the optimal cutoff value and the sensitivity, specificity, positive and negative predictions, and accuracy of the optimal cutoff value were calculated. Single factor and multivariate analysis were used to analyze the risk factors of pancreatic fistula after gastric cancer surgery. SPSS 25.0 software was used for statistical analysis.Results:The incidence of clinically relevant pancreatic fistula after surgery for gastric cancer was 5.37%(20/372), including 18 cases of grade B pancreatic fistula and 2 cases of grade C pancreatic fistula. The critical values of amylase on the first postoperative day of clinically relevant pancreatic fistula after surgery for gastric cancer are predicted to be 2036 U/L, serum CRP 18 mg/dL, and procalcitonin 0.85 μg/L. In univariate analysis, body mass index, abdominal amylase concentration on the 1st postoperative day, serum CRP and procalcitonin on the 3rd postoperative day were the influencing factors for the occurance of pancreatic fistula after gastric cancer surgery. Multivariate Logistic regression analysis showed that body mass index>25 kg/m 2, abdominal amylase >2036 U/L on the first postoperative day and serum CRP>18 mg/dL on the third postoperative day were the independent predictors for pancreatic fistula. The sensitivity and specificity of the combination of intraperitoneal amylase on the first day and serum CRP on the third day after surgery for gastric cancer in predicting the occurrence of clinically relevant pancreatic fistula were 87.6% and 90.4%, respectively. Conclusions:The combination of amylase in abdominal cavity on the 1st day and CRP on the 3rd day after radical gastrectomy has high sensitivity and specificity in predicting clinically related pancreatic fistula. PCT on the 3rd day after gastric cancer surgery has limited accuracy in predicting clinically related pancreatic fistula, so it is not recommended as an early prediction index of pancreatic fistula after gastric cancer surgery.

Bronchial asthma is the most common chronic airway disease in childhood characterized by chronic airway inflammation and airway hyperresponsiveness.The assessment of small airway function plays an important role in the diagnosis and management of asthma.This article will describe the definition of small airways, pulmonary function testing and their application in the clinical diagnosis and management of asthma.

Correlation analysis between arch index and foot kinematic parameters and their characteristics in stress fracture of lower extremity / 中华创伤杂志

Objective:To analyze the relationship between arch index and foot kinematic parameters and their characteristics in stress fracture of lower extremity.Methods:A case-control study was performed for 108 recruits selected from a certain army unit in 2019. Before training, the recruits′ foot print images were collected by the capacitive plantar pressure measurement system to calculate their arch indices. The kinematic characteristics of the foot were analyzed by the dynamic gait posture analysis system. Spearman rank correlation analysis between arch index and foot kinematic parameters including landing elevation angle, toe-off angle, landing speed, landing varus angle, valgus amplitude and landing valgus speed were performed. Throughout the training, orthopedic physicians followed up the recruits, among whom 10 were excluded due to other types of lower extremity injuries. The arch index and foot kinematic characteristics were analyzed and compared between the remained recruits with stress fracture of lower extremity (fracture group, n=10) and those without lower extremity injury (control group, n=79). Results:(1) For the recruits, the arch index was 0.21(0.12,0.25), with landing elevation angle for (17.31±4.02)°, toe-off angle for (63.90±5.63)°, landing speed for (176.85±24.39)°/s, landing varus angle for (13.64±4.44)°, valgus amplitude for (12.16±3.42)°, and landing valgus speed for 382.50(311.05,474.80)°/s. (2) The landing varus angle ( r=0.25, P<0.01) and valgus amplitude ( r=0.14, P<0.05) were positively related to the arch index. (3) The arch index, toe-off angle and landing valgus speed were 0.20(0.07,0.24), (61.59±5.51)° and 336.00(251.02,428.67)°/s in fracture group, significantly lower than 0.23(0.17,0.26), (64.79±4.79)° and 381.20(313.63,470.92)°/s in control group ( P<0.05 or 0.01). There were no significant differences in the landing elevation angle, landing speed, landing varus angle and valgus amplitude between the two groups (all P>0.05). Conclusions:The change of the arch index can affect the landing varus angle and valgus amplitude of the foot. Recruits who suffer from stress fracture of lower extremity have the characteristics of higher arch, lower toe-off angle and lower landing valgus speed.

Related factors affecting the occurrence of severe pancreatic fistula after radical gastrectomy / 中国基层医药

Objective:To investigate the related factors that affect the occurrence of severe pancreatic fistula after radical gastrectomy.Methods:The clinical data of 460 patients undergoing radical gastrectomy in The People's Hospital of Shouguang from January 2015 to January 2021 were retrospectively analyzed. These patients were divided into severe pancreatic fistula group ( n = 24) and non-severe pancreatic fistula group ( n = 436) according to whether they developed severe pancreatic fistula after surgery. Preoperative clinical data, surgical data, and abdominal drainage fluid amylase level in the first postoperative days were compared. The receiver operating characteristics (ROC) curve was used to calculate the cutoff value of abdominal drainage fluid amylase level on the 1 st and 3 rd days of developing severe pancreatic fistula after radical gastrectomy. The incidence of pancreatic fistula was compared between different amylase level groups. Multivariate logistic regression was performed to analyze the independent risk factors of severe pancreatic fistula after surgery. Results:There were significant differences in body mass index, operative time, intraoperative blood loss, peritoneal drainage fluid amylase level on the 1 st and 3 rd days after surgery, and the number of cases undergoing splenectomy between the two groups (all P < 0.05). The cutoff values of amylase level in peritoneal drainage fluid (D-AMY) on the 1 st and 3 rd days after surgery were 2 156 IU/L and 596 IU/L respectively, which had high sensitivity and specificity. On the 1 st and 3 rd days after surgery, the incidence of pancreatic fistula in the high-level amylase group was significantly higher than that in the low-level amylase group [26.2% (16/61) vs. 0.8% (3/334), χ2 = 62.82, P < 0.05). Multivariate logistic analysis showed that obesity, splenectomy, and abdominal drainage fluid amylase level higher than the cut-off value on the 1 st and 3 rd days after surgery were independent risk factors for severe pancreatic fistula, and the differences were statistically significant (all P < 0.05). Conclusion:Obesity, splenectomy, and abdominal drainage fluid amylase level higher than the cut-off value on the 1 st and 3 rd days after surgery are independent risk factors affecting the occurrence of severe pancreatic fistula. D-AMY (> 2 156 IU/L) on the 1 st day and D-AMY (> 596 IU/L) on the 3 rd day in the early postoperative days can be used as cutoff values to predict the occurrence of severe pancreatic fistula after radical gastrectomy.

Study on the effect of discharge preparation service in elderly patients with hip fractures / 中国实用护理杂志

[Objective]:To explore the effect evaluation of discharge preparation service on elderly patients with hip fractures.Methods:Totally 80 elderly patients with hip fractures admitted to Shanghai Sixth People′s Hospital from April 2019 to October 2019 were selected as the research objects, and they were divided into intervention group and control group according to admission time, 40 patients in each group. The control group was given routine nursing care, and the intervention group was given readiness service for hospital discharge.The application effect of the scheme was evaluated by the degree of readiness for discharge and the quality of discharge guidance, Barthel index score, Harris score and incidence of complications.Results:In the intervention group,the total score of readiness for hospital discharge of patients was 83.43±8.10,the total score of the quality of discharge guidance was 151.30±16.61,while those in the control group were 77.13 ± 9.30, 141.58 ± 18.34, the differences between the two groups were statistically significant( t=3.23, 2.49, both P<0.05).In terms of the follow-up after patients were discharged for 3 months, the Harris hip score and Barthel index scores for patients with hip fracture were 82.53 ± 7.83 and 88.13 ± 3.34,while those were 76.03 ± 12.15, 86.13 ± 2.65 in the control group,the differences between the two groups were statistically significant ( t=2.84, 2.97, both P<0.05). Conclusions:The discharge preparation service can effectively improve the readiness for hospital discharge and the quality of discharge guidance. It improves the hip joint function, the quality of life of patients, and the clinical outcome of patients effectively.

The clinical significance of pulmonary function tests in children with community acquired pneumonia / 国际儿科学杂志

Objective:To explore the value of early pulmonary function tests in children with community acquired pneumonia(CAP)by analyzing the clinical and imaging manifestations and pulmonary function tests of children with CAP.Methods:The clinical data of children diagnosed with CAP and undergoing routine pulmonary ventilation tests within 24 hours of admission were retrospectively collected from January 2016 to June 2018 in the Department of Pediatric Respiratory Medicine of Shengjing Hospital Affiliated to China Medical University.The children′s pulmonary ventilation function test data were statistically analyzed with clinical manifestations, laboratory tests and imaging data.Results:A total of 154 children were included in the study, of which 54(35.06%)had normal pulmonary ventilation function, and the remaining 100 children(64.94%)had different degrees of pulmonary ventilation impairment, which were manifested as restrictive ventilation disorder in 54 cases(35.06%), obstructive ventilation disorder in 8 cases(5.19%), mixed ventilation disorder in 30 cases(19.48%), and small airway ventilation dysfunction in 8 cases(5.19%). According to the results of pulmonary ventilation function, the mixed ventilation dysfunction group had a greater probability of pulmonary imaging changes to consolidation than the normal group( χ2=7.83, P=0.007). Mycoplasma pneumoniae infection was negatively correlated with forced expiratory volume in the first second, 75% forced expiratory flow, one second rate and maximal mid-expiratory flow level( r=-0.23, r=-0.22, r=-0.25, r=-0.23, all P<0.05), and there was no significant correlation with the level of forced vital capacity. Conclusion:Early pulmonary ventilation test has important clinical significance in the diagnosis and treatment of CAP in children.

Measurement of Structure and Stiffness of Gastrocnemius Muscle for Stroke Patients with Multimodal Ultrasound Imaging / 中国康复理论与实践

Objective:To apply multimodal ultrasound imaging in spasticity assessment for stroke patients with hemiplegia. Methods:From March to September, 2019, 44 inpatients with lower limb spastic hemiplegia after stroke (patients) and 46 healthy volunteers (controls) were scanned with two-dimensional ultrasound imaging, shear wave elastography and super microvascular imaging at the same area of gastrocnemius muscle of both sides of patients and right side of controls, in resting and maximum isometric contraction. The parameters of shear wave velocity (SWV), blood flow signal, pinnation angle (PA), fascicle length (FL) and muscle thickness (MT) were recorded. Results:SWV increased in the affected side of the patients compared with those of the unaffected side and controls in resting (t > 6.346, P < 0.01), while FL shortened (|t| > 6.235, P < 0.01), MT and PA changed compared with those of the unaffected side (|t| > 2.198, P < 0.05), and blood flow signal decreased compared with those of the controls (t = 2.604, P < 0.05). In maximum isometric contraction, the decrease of FL was less compared with those of the unaffected side and controls (Z > 6.703, P < 0.001). Conclusion:Ultrasound imaging can quantitatively evaluate spasticity of gastrocnemius muscle for patients with stroke in terms of morphological structure, blood flow, and muscle stiffness.

Role of peak expiratory flow in the assessment and management of asthma in children / 中国当代儿科杂志

Peak expiratory flow (PEF) is a portable, reliable, and inexpensive method for lung function assessment. PEF can reflect expiratory airflow limitation and its variability can document reversibility, which provides an objective basis for the diagnosis of asthma in children. Short-term PEF monitoring can be an important aid in the management of acute asthma exacerbations, identification of possible triggers, and assessment of response to treatment. Long-term PEF monitoring can assist in the assessment of asthma control and warning of acute exacerbations, and this is useful for children with severe asthma. This article reviews the measurements, influencing factors, interpretation, and application of PEF, and its role in the diagnosis and management of asthma in children, to provide references for the clinical application of PEF in children.

Correlation between bronchial dilation test and asthma control level in children with asthma / 中国当代儿科杂志

OBJECTIVE@#To study the correlation between the bronchial dilation test (BDT) and asthma control level in children with asthma.@*METHODS@#A total of 153 children with asthma, aged 5-14 years, who attended the outpatient service from March 2016 to March 2018 were enrolled. According to the presence or absence of atopic constitution, they were divided into an allergic group with 79 children and a non-allergic group with 74 children. The correlation between BDT and Childhood Asthma Control Test (C-ACT) scores was analyzed for both groups.@*RESULTS@#All basic pulmonary function parameters were positively correlated with C-ACT scores in the non-allergic group (@*CONCLUSIONS@#The improvement rate of BDT is well correlated with C-ACT scores in children with asthma, suggesting that BDT can be used as an index for predicting asthma control level.
