MethodA randomized， open， parallel controlled， and multi-center clinical study was conduted. Children with acute bronchitis （syndrome of phlegm-heat obstructing lung） were randomly assigned to an observation group and a control group. The control group received routine basic treatment， and the observation group was treated with Lianhua Qingke Tablets on the basis of routine basic treatment. After 7 days of treatment， the clinical efficacy， TCM efficacy， time to symptom disappearance， time to cough disappearance， and clinical safety were compared between the two groups. ResultA total of 248 children were included （124 in the observation group and 124 in the control group）. After 7 days of treatment， the total response rate in terms of clinical efficacy in the observation group was 96.8% （120/124）， which was higher than that （90.3%， 112/124） in the control group （Z=-5.034， P<0.01）. The total response rate in terms of TCM syndrome in the observation group was 97.6% （121/124）， which was higher than that （93.5%， 116/124） in the control group （χ2=-5.326， P<0.01）. The scores of physical signs and TCM symptoms in the observation group were lower than those in the control group at the time of taking medicine for 3 days and 7 days （P<0.01）. The time to symptom disappearance and the time to cough disappearance in the observation group were shorter than those in the control group （P<0.01）. Drug-related adverse reactions occurred in neither group. ConclusionLianhua Qingke tablets demonstrate a definite effect on acute bronchitis in children with the syndrome of phlegm-heat blocking lung.

ABSTRACT
ObjectiveTo investigate the impact of early intervention with Yishen Huazhuo prescription （YHP） on the learning and memory of accelerated aging model mice， as well as its underlying mechanism. MethodForty-eight 3-month-old male SAMP8 mice were randomly assigned into four groups， including the model group， low-dose YHP group， high-dose YHP group， and donepezil group. Additionally， 24 SAMR1 mice of the same age were divided into a control group and a YHP treatment control group， each consisting of 12 mice. The YHP groups received YHP at doses of 6.24 g·kg-1 and 12.48 g·kg-1， while the donepezil group was treated with donepezil at a dose of 0.65 mg·kg-1. The model group and control groups were given physiological saline. The mice were gavaged once daily for a duration of four weeks. Spatial learning and memory abilities of mice were assessed using the Morris water maze test. Immunofluorescence staining was employed to evaluate neuronal density as well as expression levels of M1 microglial （MG） polarization marker inducible nitric oxide synthase （iNOS） and M2 MG polarization marker arginase-1 （Arg-1） in the hippocampus region. Enzyme-linked immunosorbent assay （ELISA） was used to measure serum levels of pro-inflammatory factor interleukin 1β （IL-1β） and anti-inflammatory factor transforming growth factor-β1 （TGF-β1）. Furthermore， Western blot analysis was conducted to determine expressions of amyloid β peptide1-42 （Aβ1-42） along with triggering receptor expressed on myeloid cells 2 （TREM2）/nuclear factor kappa B （NF-κB） signaling pathway-related proteins TREM2， phospho （p）-NF-κB p65， and phospho-inhibitory kappa B kinase β （IKKβ） in the hippocampus. ResultCompared with the control group， the model group exhibited a significantly prolonged escape latency （P<0.01）， a significant reduction in neuron-specific nuclear protein （NeuN） expression in the hippocampus， a significant increase in iNOS expression in MG， and a significant decrease in Arg-1 expression. The serum IL-1β content was significantly increased， while the TGF-β1 content was significantly decreased. Additionally， there was a significant decrease in TREM2 expression in the hippocampus and significant increases in p-NF-κB p65， p-IKKβ， and Aβ1-42 expressions （P<0.05， P<0.01）. However， no significant changes were observed in escape latency， times of crossing the platform， and hippocampal NeuN expression in the YHP treatment control group. Conversely， iNOS expression in MG as well as the hippocampal p-NF-κB p65， p-IKKβ， and Aβ1-42 expressions were significantly decreased. Furthermore， TREM2 expression was significantly increased （P<0.05， P<0.01）. In comparison to the model group， the low-dose YHP group showed a significantly shortened escape latency and an increased number of crossing the platform （P<0.05， P<0.01）. In the high-dose YHP group， the escape latency was significantly shortened （P<0.05）. In the low-dose YHP group， high-dose YHP group， the expression of NeuN in the hippocampus was significantly increased， the expression of iNOS in MG was significantly decreased， and the expression of Arg-l was significantly increased. The serum IL-1β content was significantly decreased， while the TGF-β1 content was significantly increased. Furthermore， the expression of TREM2 in the hippocampus was significantly increased， and the expressions of p-NF-κB p65， p-IKKβ， and Aβ1-42 were significantly decreased （P<0.01）. ConclusionEarly YHP intervention may promote the transformation of hippocampal MG from M1 to M2 by regulating the TREM2/NF-κB signaling pathway， reduce the release of neuroinflammatory factors， protect hippocampal neurons， and reduce the deposition of Aβ1-42， and finally delay the occurrence of learning and memory decline in SAMP8 mice.
ABSTRACT
Hypospadias is a common congenital malformation in the male urethra and external genitalia, which can be successfully treated with surgery. Various surgical treatments are available. Based on the repair criteria for restoring function and appearance, surgical treatments require the complete correction of the penile curvature, repair of the urethra to the head of the penis, and acquisition of a fissure-like opening. The local anatomical characteristics of hypospadias should be taken into consideration to formulate an individualized surgical treatment plan.

OBJECTIVES@#Long-term elevated blood pressure may lead to kidney damage, yet the pathogenesis of hypertensive kidney damage is still unclear. This study aims to explore the role and significance of leucine-rich alpha-2-glycoprotein-1 (LRG-1) in hypertensive renal damage through detecting the levels of LRG-1 in the serum and kidney of mice with hypertensive renal damage and its relationship with related indexes.@*METHODS@#C57BL/6 mice were used in this study and randomly divided into a control group, an angiotensin II (Ang II) group, and an Ang II+irbesartan group. The control group was gavaged with physiological saline. The Ang II group was pumped subcutaneously at a rate of 1.5 mg/(kg·d) for 28 days to establish the hypertensive renal damage model in mice, and then gavaged with equivalent physiological saline. The Ang II+irbesartan group used the same method to establish the hypertensive renal damage model, and then was gavaged with irbesartan. Immunohistochemistry and Western blotting were used to detect the expression of LRG-1 and fibrosis-related indicators (collagen I and fibronectin) in renal tissues. ELISA was used to evaluate the level of serum LRG-1 and inflammatory cytokines in mice. The urinary protein-creatinine ratio and renal function were determined, and correlation analysis was conducted.@*RESULTS@#Compared with the control group, the levels of serum LRG-1, the expression of LRG-1 protein, collagen I, and fibronectin in kidney in the Ang II group were increased (all P<0.01). After treating with irbesartan, renal damage of hypertensive mice was alleviated, while the levels of LRG-1 in serum and kidney were decreased, and the expression of collagen I and fibronectin was down-regulated (all P<0.01). Correlation analysis showed that the level of serum LRG-1 was positively correlated with urinary protein-creatinine ratio, blood urea nitrogen, and blood creatinine level in hypertensive kidney damage mice. Serum level of LRG-1 was also positively correlated with serum inflammatory factors including TNF-α, IL-1β, and IL-6.@*CONCLUSIONS@#Hypertensive renal damage mice display elevated expression of LRG-1 in serum and kidney, and irbesartan can reduce the expression of LRG-1 while alleviating renal damage. The level of serum LRG-1 is positively correlated with the degree of hypertensive renal damage, suggesting that it may participate in the occurrence and development of hypertensive renal damage.

BACKGROUND@#Ischemic acute kidney injury (AKI) is a common syndrome associated with considerable mortality and healthcare costs. Up to now, the underlying pathogenesis of ischemic AKI remains incompletely understood, and specific strategies for early diagnosis and treatment of ischemic AKI are still lacking. Here, this study aimed to define the transcriptomic landscape of AKI patients through single-cell RNA sequencing (scRNA-seq) analysis in kidneys.@*METHODS@#In this study, scRNA-seq technology was applied to kidneys from two ischemic AKI patients, and three human public scRNA-seq datasets were collected as controls. Differentially expressed genes (DEGs) and cell clusters of kidneys were determined. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis, as well as the ligand-receptor interaction between cells, were performed. We also validated several DEGs expression in kidneys from human ischemic AKI and ischemia/reperfusion (I/R) injury induced AKI mice through immunohistochemistry staining.@*RESULTS@#15 distinct cell clusters were determined in kidney from subjects of ischemic AKI and control. The injured proximal tubules (PT) displayed a proapoptotic and proinflammatory phenotype. PT cells of ischemic AKI had up-regulation of novel pro-apoptotic genes including USP47 , RASSF4 , EBAG9 , IER3 , SASH1 , SEPTIN7 , and NUB1 , which have not been reported in ischemic AKI previously. Several hub genes were validated in kidneys from human AKI and renal I/R injury mice, respectively. Furthermore, PT highly expressed DEGs enriched in endoplasmic reticulum stress, autophagy, and retinoic acid-inducible gene I (RIG-I) signaling. DEGs overexpressed in other tubular cells were primarily enriched in nucleotide-binding and oligomerization domain (NOD)-like receptor signaling, estrogen signaling, interleukin (IL)-12 signaling, and IL-17 signaling. Overexpressed genes in kidney-resident immune cells including macrophages, natural killer T (NKT) cells, monocytes, and dendritic cells were associated with leukocyte activation, chemotaxis, cell adhesion, and complement activation. In addition, the ligand-receptor interactions analysis revealed prominent communications between macrophages and monocytes with other cells in the process of ischemic AKI.@*CONCLUSION@#Together, this study reveals distinct cell-specific transcriptomic atlas of kidney in ischemic AKI patients, altered signaling pathways, and potential cell-cell crosstalk in the development of AKI. These data reveal new insights into the pathogenesis and potential therapeutic strategies in ischemic AKI.

With a rapidly aging population， there is a huge potential demand for rehabilitation and assistive products and services. Especially in the global context where greater attention is given to disadvantaged groups， there is a need to cater to the needs of the elderly in terms of rehabilitation and assistive aid to improve their quality of life. Compared with developed countries， China’s rehabilitation aid industry is still in its early stages of development and needs to move away from traditional equipment manufacturing and integrate with intelligent manufacturing to provide more development possibilities and choices. International cooperation is expected to become one of the future research and development directions for rehabilitation aids. Taking typical cities and countries at home and abroad as examples， this paper explores the development of rehabilitation aids， and calls for the cultivation of more rehabilitation aid professionals to help more people in need.
ABSTRACT
Objective:To analyze the clinical efficacy of treatment of cement dislodgement after vertebral augmentation for osteoporotic vertebral fractures.Methods:A retrospective study was conducted to analyze the data of 13 patients who had been treated at Department of Orthopaedics, The First Affiliated Hospital of Soochow University for cement dislodgement after vertebral augmentation for osteoporotic vertebral fractures from July 2013 to July 2022. There were 4 males and 9 females, with an average age of (76.5±8.6) years and a T value of bone mineral density of -3.3±0.6. By the CT and MRI features of cement dislodgement, their conditions fell in 4 types: cement loosening in situ (4 cases), anterior cement moving (6 cases), anterior cement moving with posterior bone mass moving (2 cases), and posterior cement moving (1 case). They were treated by percutaneous vertebroplasty (3 cases), pedicle screw fixation combined with bone graft fusion and decompression (7 cases), and conservative therapy (3 cases). The curative effects for surgical patients were evaluated by comparing their visual analogue scale (VAS), Oswestry dysfunction index (ODI) and cobb angle of kyphosis at preoperation, 1 week and 1 month postoperation, and the last follow-up, and Frankel grading for nerve injury as well. The curative effects for patients undergoing conservative treatment were evaluated by observing their symptoms.Results:This cohort was followed up for 7 (5, 12) months after treatment. The VAS scores [5.0 (4.0, 5.0) points, 3.0 (2.0, 3.0) points, and 3.0 (2.0, 3.0) points] in the 10 surgical patients at 1 week and 1 month postoperation and the last follow-up were significantly improved compared with the preoperative value [8.5 (8.0, 9.0) points] ( P<0.05); the VAS scores at 1 month postoperation and the last follow-up were also significantly improved compared with that at 1 week postoperation ( P < 0.05), but there was no significant difference between the last follow-up and 1 month postoperation ( P > 0.05). The ODIs (50.6%±4.2%, 37.8%±4.5%, and 29.3%±5.6%) in the 10 surgical patients at 1 week and 1 month postoperation and the last follow-up were significantly improved compared with the preoperative value (93.2%±3.6%), showing significant differences in pairwise comparisons ( P<0.05). The cobb angles [10.0 (9.0, 11.0)°, 9.0 (9.0, 11.0)°, and 10.0 (9.0, 12.0)°] in the 10 surgical patients at 1 week and 1 month postoperation and the last follow-up were significantly improved compared with the preoperative value [12.5 (11.0, 14.0)°] ( P<0.05) , but there was no statistically significant difference between the time points after operation ( P>0.05). The Frankel grading was significantly improved in the 6 patients with nerve injury after operation. Of the 3 patients undergoing conservative treatment, the symptoms were cured in one, showed no change during follow-up in one, and aggravated in one. Conclusion:Surgical treatment can significantly relieve pain, improve spinal dysfunction and repair nerve injury in patients with bone cement dislodgement after vertebral augmentation.
ABSTRACT
Objective:To improve the understanding of hemodialysis complicated with mesenteric artery calcified stenosis and mesenteric ischemia through the analysis of the case and review of related literature.Methods:A case of hemodialysis with intractable abdominal pain as the main manifestation was reported, and its clinical features, diagnosis and treatment were summarized.Results:The case was a maintenance hemodialysis patient with persistent dull pain around the umbilicus, which worsens after meal and hemodialysis.

Surgical treatment was recommended, but the patient and family refused surgery and were discharged.Conclusions:Dialysis patients with intractable abdominal pain should be carefully identified and alert for mesenteric artery disease and mesenteric ischemia.
ABSTRACT
ObjectiveTo investigate the current situation of rehabilitation therapists' work, and analyze the factors related to their career development and transformation. MethodsFrom September, 2022 to January, 2023, 153 rehabilitation therapists in Weifang were investigated with a cross-sectional questionnaire, using general questionnaire, Job Satisfaction Scale for Grassroots Health Technicians, Social Responsibility Scale, Job Role and Identity Inventory, and Employee Turnover Scale. ResultsThe majority of rehabilitation therapists interviewed were male (52.28%), under 35 years old (88.24%), with a bachelor's degree (77.78%), income less than 5 000 yuan a month (46.40%), and less than five years of service (48.36%). The work time was (7.78±0.84) hours a day, (5.39±0.51) days a week. The favorable rate of the physical environment of work was 67.32%, and the favorable rate of the interpersonal relationship environment of work was 80.39%. The score of professional identity was (3.61±0.84), the score of job satisfaction was (3.62±0.97), the score of social responsibility was (3.53±0.79), and the score of turnover was (2.39±1.10). Education level, job satisfaction, and social responsibility were the main factors related to the employee turnover (P < 0.05). ConclusionThe overall educational level of rehabilitation therapists is relatively low, and the human resource structure needs to be optimized. There is a significant difference between academic education and continuing education, and career development needs to be improved. The main factors related to career development and transformation are education level, job satisfaction, and social responsibility.
ABSTRACT
Objective:To evaluate the dose-effect relationship of compound lidocaine hydrochloride for transverse abdominal plane-rectus abdominis sheath block (TAP-RSB) for postoperative analgesia in elderly patients undergoing laparoscopic radical colon cancer surgery with general anesthesia.Methods:Elderly patients of either sex, aged≥65 yr, with body mass index <30 kg/m 2, of American Society Anesthesiologists physical status Ⅰ-Ⅲ, undergoing elective laparoscopic radical colon cancer surgery with general anesthesia, were selected.After induction of general anesthesia, compound lidocaine hydrochloride was given under ultrasound guidance for bilateral TAP block (20 ml on each side) and for bilateral RSB (10 ml on each side), with the initial concentration of 0.4%.Each time the concentration increased/decreased in the next patient depending on whether or not the analgesia was effective.The ratio between the two successive concentrations was 1.00∶1.15.The analgesic effects were evaluated by the Numerical Rating Scale at 1 h intervals from the time of postoperative admission to the post-anesthesia care unit until 8 h after TAP-RSB (Numerical Rating Scale ≤ 3 was considered as effective analgesia). The probit method was used to calculate the half effective concentration (EC 50) and 95% effective concentration (EC 95) and 95% confidence interval of compound lidocaine hydrochloride. Results:The EC 50 and EC 95(95% confidence interval)of compound lidocaine hydrochloride for TAP-RSB were 0.289% (0.232%-0.352%) and 0.404% (0.345%-0.970%), respectively, when used for postoperative analgesia in elderly patients undergoing laparoscopic radical colon cancer surgery with general anesthesia. Conclusions:The EC 50 and EC 95 of compound lidocaine hydrochloride for TAP-RSB are 0.289% and 0.404%, respectively, when used for postoperative analgesia in elderly patients undergoing laparoscopic radical colon cancer surgery with general anesthesia.
ABSTRACT
DNA damage repair (DDR) system plays an important role in maintaining of genomic stability. Accumulation of DNA lesions or deficiency of DDR system could drive tumorigenesis as well as promote tumor progression; meanwhile, they could also provide therapeutic opportunities and targets. Of all the antineoplastic agents of lung cancers, many of them targeted or were associated with DNA damage and repair pathways, such as chemotherapies and antibody-drug conjugates which were designed directly causing DNA damages, targeted drugs inhibiting DNA repair pathways, and immune-checkpoint inhibitors. In this review, we described the role of DNA damage and repair pathways in antitumor activity of the above agents, as well as summarized the application and clinical investigations of these antineoplastic agents in lung cancers, in order to provide more information for exploring precision and effective strategies for the treatment of lung cancer based on the mechanism of DNA damage and repair. .

Due to primary diseases of neurocritical care unit (NCU) patients, they have particularities with low level of consciousness, poor airway protective ability, damaged respiratory drive and respiratory motor conduction pathway. Such patients have higher rates of weaning difficulty, delayed extubation, extubation failure and tracheostomy. There are several guidelines on weaning and extubation for intensive care unit (ICU) patients, while there are no guidelines for for NCU patients. Therefore, we reviewed current guidelines and recommendations on weaning and extubation in both ICU and NCU patients suggesting considerations of neurological condition, level of consciousness and presence of airway protective reflexes before extubation, moreover, we introduced researches about protocols of weaning for NCU patients and related predictors.
ABSTRACT
Objective@#To analyze the effect of sunlike spectrum LED illumination on retinal blood flow perfusion, and to explore the the correlation between sunlike spectrum LED illumination and eye health indicators in children and adolescents.@*Methods@#A randomized control double blind trial was conducted. The ordinary LED table lamp in the control group(11) and the sunlike spectrum LED table lamp in the experimental group(12) had a fitting degree of 87% and 95% with the daylighting spectrum, respectively. Two sample independent t test and multivariable linear regression model were applied to compare the changes of retinal blood perfusion before and after the trial.@*Results@#After near reading for 1 hour, the retinal capillary density in the superficial and deep layers of the subjects in the ordinary LED illumination group decreased (superficial layer: -3.05±2.04 , P <0.01; deep layer: -4.03± 4.94, P =0.02), no significant decrease was found in the sunlike spectrum LED illumination group (superficial layer: -0.59± 1.44, P =0.18; deep layer: -0.49±4.27, P =0.70). Multivariable regression analysis found that compared with ordinary LED illumination, sunlike spectrum LED illumination could significantly alleviate the decrease in capillary density in the superficial and deep retinal layers, respectively ( β =2.83, 95% CI =1.54-4.12, P <0.01; β =4.21,95% CI =0.58-7.84, P =0.02).@*Conclusion@#Sunlike spectrum LED illumination can alleviate the decrease in retinal blood perfusion caused by near work among children and adolescents, suggesting that it may delay the onset and development of myopia. Prevention and control of myopia needs to pay attention to the spectral power distribution of artificial illumination.
ABSTRACT
Immune checkpoint inhibitors (ICIs) have become an important means of cancer treatment, and their application in the clinic is becoming more and more widespread. The adverse reactions caused by ICIs are gradually recognized. Among them, immunotherapy-related diabetes is a rare adverse reaction and type 1 diabetes mellitusis common. With the wide application of ICIs combined with chemotherapy in lung cancer patients, patients with type 2 diabetes mellitus have gradually been discovered during the treatment. However, the effect of continued use of ICIs maintenance therapy on blood glucose and ICIs treatment process in these patients is still unclear. This article reports two cases of type 2 diabetes mellitus induced by immune checkpoint inhibitor combined with chemotherapy, one of whom converted to type 1 diabetes mellitus, in order to increase the understanding of immunotherapy-related diabetes. .

Immune checkpoint inhibitors (ICIs) are widely used in clinic, and the incidence of rare adverse events are increasing. The aim of this paper is to better define the rare adverse effect of diabetes mellitus associated with ICIs. We report 2 cases of diabetes mellitus associated with ICIs. Literature review was conducted and we discussed the clinical presentation, potential mechanisms and suggestions for optimal management. Two patients were both elderly women, case 1 had increased blood glucose after 7 months of using Durvalumab, and cases 2 had diabetic ketoacidosis after 6 weeks of using Pembrolizumab. Both patients were administered exogenous insulin to control blood glucose. Case 1 has been treated with Durvalumab until now and case 2 discontinued using of Pembrolizumab. HLA genotypes and other factors may explain the risk factors of diabetes associated with ICIs in some individuals. Diabetes mellitus associated with ICIs is an uncommon but potentially life-threatening endocrine system adverse event, which requires doctors to be vigilant. The patients who use ICIs need to monitor blood glucose. If they have hyperglycemia, endocrinologists should be asked to assist in diagnosis and treatment. .

Objective:To evaluate the relationship between CCL21 and triggering receptor expressed on myeloid cells 2 (TREM2)/DNAX-activating protein of 12 kDa (DAP12) signaling pathways in the spinal dorsal horn in remifentanil-induced hyperalgesia in mice with incisional pain.Methods:Thirty-two SPF healthy male C57BL/6J mice, weighing 18-22 g, aged 8-10 weeks, were divided into 4 groups ( n=8 each) using a random number table method: control group (group C), CCL21 neutralizing antibody group (group anti-CCL21), remifentanil + incisional pain group (group R+ I), and CCL21 neutralizing antibody + remifentanil + incisional pain group (group anti-CCL21+ R+ I).A CCL21 neutralizing antibody 0.3 μg (diluted to 10 μl in normal saline) was intrathecally injected in anti-CCL21 and anti-CCL21+ R+ I groups twice a day.Normal saline 10 μl was intrathecally injected at the same time point twice a day in C and R+ I groups.Fifteen min after intrathecal injection, normal saline 0.1 ml was injected via the caudal vein for 4 consecutive times at an interval of 15 min in C and anti-CCL21 groups, and remifentanil 10 μg/kg (diluted to 0.1 ml in normal saline) was injected via the caudal vein for 4 consecutive times at an interval of 15 min in R+ I and anti-CCL21+ R+ I groups.The tail-flick latency (TFL) and mechanical paw withdrawal threshold (MWT) were measured at 24 h before remifentanil or normal saline injection (T 0) and 3, 6, 24 and 48 h after stopping injection of remifentanil or normal saline (T 1-4).The mice were sacrificed after the last measurement of pain threshold, and L 4-6 segments of the spinal cord were removed for determination of the expression of TREM2 and DAP12 protein and mRNA (by Western blot or quantitative real-time polymerase chain reaction). Results:Compared with group C, TFL was significantly shortened and MWT was decreased at T 1-4, and the expression of TREM2 and DAP12 protein and mRNA was up-regulated in group R+ I and R+ I+ anti-CCL21 ( P<0.05), and no significant change was found in the parameters mentioned above in group anti-CCL21 ( P>0.05).Compared with group R+ I, TFL was significantly prolonged and MWT was increased at T 1-4, and the expression of TREM2 and DAP12 protein and mRNA was down-regulated in group anti-CCL21+ R+ I ( P<0.05). Conclusions:CCL21 is involved in remifentanil-induced hyperalgesia by activating TREM2/DAP12 signaling pathways in the spinal dorsal horn of mice with incisional pain.
