Adolescent idiopathic scoliosis(AIS)is a complex three-dimensional deformity involving coronal,sagittal,and axial planes,with a prevalence that should not be overlooked.With advancements in technology and in-depth research,an increasing number of hospitals and physicians are exploring standardized diagnostic and treatment approaches for AIS.Comprehensive and in-depth understanding is required for AIS,including its etiology,screening and diagnosis,classification,assessment and examination,treatment options,exploration of current focus,and evaluation of quality of life.Such understanding ensures that the diagnostic and treatment are scientific,standardized,and timely.Based on the principles of evidence-based medicine,a consensus on the diagnosis and treatment of AIS is reached after multiple discussions among spinal surgery experts,aiming to provide reference and guidance for clinical practice.

Objective:To observe the efficacy and safety of combined lienal polypeptide injection therapy in the treatment of Mycoplasma pneumoniae pneumonia（MPP）in children aged 3 to 14 years old in multiple clinical centers.Methods:A randomized，controlled，multi-center clinical study design was adopted.A total of 240 hospitalized children aged 3 to 14 years old with MPP from 7 hospitals from September 1，2023 to January 31，2024 were included.According to the severity of pneumonia，they were divided into the mild MPP group with 80 cases and the severe MPP/refractory MPP（SMPP/RMPP）group with 160 cases，and then randomly divided into the control group and the experimental group at a ratio of 1 ∶1，using the random number table method.After screening，subjects entered a treatment period of 5 to 7 days.The control group was treated with azithromycin，while the experimental group was treated with azithromycin plus lienal polypeptide injection .The recovery of lung CT，length of hospital stay，duration of fever，cough score，whether mild cases developed into severe or refractory cases，duration of hormone use，use of intravenous immunoglobulin（IVIG），bronchoscopy treatment，and immune function were observed between the two groups to evaluate the efficacy of lienal polypeptide injection.Adverse events after medication，vital signs，blood routine，urine routine，liver function，myocardial enzymes，renal function，and electrocardiogram were observed to evaluate the safety. Results:A total of 231 subjects have completed the trial in the 7 hospitals，including 118 cases in the experimental group and 113 cases in the control group.Main observation index：the rate of lung CT aggravation in the experimental group was lower than that in the control group（2.6% vs 15.3%， P<0.01），and the difference was statistically significant.Secondary indexes：there were no statistically significant differences in the length of hospital stay，duration of fever，cough score，duration of hormone use，whether IVIG treatment was used，the number of bronchoscopy treatment cases，and immunoglobulin between the two groups（all P>0.05）.However，the rate of cases of plastic bronchitis（PB）found under bronchoscopy in the experimental group was lower than that in the control group（0 vs 18.8%， P=0.03），and the difference was statistically significant.Among the mild MPP（72 cases），there were no statistically significant differences in the length of hospital stay，duration of fever，cough score，duration of hormone use，whether IVIG treatment was used，the number of bronchoscopy treatment cases，and the improvement rate of lung CT between the two groups（all P>0.05）.However，compared with the control group，the rate of cases developing into SMPP/RMPP in the experimental group was less（24.3% vs 48.6%， P=0.03），and the difference in IgG before and after treatment was small［0.53（-0.04，1.18）g/L vs 1.33（0.48，2.25）g/L， P=0.01］.Among the SMPP/RMPP cases（159 cases），the rate of cases of PB found under bronchoscopy in the experimental group was less than that in the control group（0 vs 20%， P=0.04），and the rate of cases with aggravated lung CT in the experimental group was less than that in the control group（1.3% vs 19.5%， P<0.01），and the improvement rate of lung CT in the experimental group was higher than that in the control group（88.8% vs 75.3%， P=0.03），with statistically significant differences.There were no statistically significant differences in the length of hospital stay，duration of fever，cough score，duration of hormone use，whether IVIG treatment was used，the number of bronchoscopy treatment cases，and immunoglobulin between the two groups（all P>0.05）.Two cases in the experimental group developed rashes，which improved after the drug was discontinued.There were no serious adverse reactions such as abnormal vital signs like dyspnea and cyanosis due to the use of lienal polypeptide injection.There were no obvious changes in blood routine，liver function，myocardial enzymes，renal function，electrocardiogram，and urine routine values before and after medication compared with the baseline. Conclusion:The combined use of lienal polypeptide injection in the treatment of MPP in children can reduce the probability of the transformation from mild cases to SMPP/RMPP，reduce the rate of aggravation of the image findings，promote the absorption of lung inflammation，reduce the rate of PB found under bronchoscopy，and has good safety.

Objective:To explore the clinical effects of free anterolateral thigh perforator flaps in repairing diabetic foot ulcers (DFUs) under a multi-disciplinary team (MDT) cooperation model.Methods:The study was a retrospective observational study. From June 2018 to December 2022, 49 DFU patients who met the inclusion criteria were admitted to the Department of Hand and Foot Microscopy and Wound Repair Surgery of Henan Provincial People's Hospital (People's Hospital of Zhengzhou University), including 28 males and 21 females, aged from 47 to 68 years, with type 2 diabetes history period ranging from 6 months to 21 years. Under a MDT cooperation model, the physicians from department of endocrinology comprehensively assessed the patients, stabilized the patients' general condition, and controlled their complications, the surgeons from department of vascular surgery assessed and improved the patients' lower limb blood supply, the physicians from department of infectious diseases provided anti-infection treatment plans, the physicians from department of anesthesiology and perioperative medicine assessed the patients' perioperative risk and ensured their perioperative safety, and according to the patients' condition, the physicians from departments such as cardiology, neurology, nutrition, and rehabilitation actively and timely participated in the treatment. The surgeons from department of hand and foot microscopy and wound repair surgery prepared the wound base and used free anterolateral thigh perforator flaps to repair the wounds. After once or multiple debridement in the first stage, the wound area ranged from 5.0 cm×4.5 cm to 17.0 cm×10.0 cm. After once or twice vacuum sealing drainage treatment, the free anterolateral thigh perforator flaps were used to repair the wounds with incision area of 6 cm×5 cm to 18 cm×11 cm in the second stage. The descending branches of lateral circumflex femoral artery and the accompanying veins of flaps were anastomosed to the arteries and veins in the recipient sites, respectively. The wounds in the flap donor sites were sutured directly. After surgery, whether the patient's perioperative period was stable, the survival of flaps, the healing of wounds in the flap donor and recipient sites were observed. During the follow-up, the texture and appearance of flaps, whether there was a new ulcer, and the patient's walking ability were observed.Results:All the patients had stable perioperative period. Among them, the flaps in 46 patients survived successfully; the flaps in 2 patients developed complete necrosis, including 1 case whose ulcer was healed after repair of pedicled flap from the lower leg, and 1 case who underwent amputation of the lower leg; the flap in 1 patient developed partial necrosis, which was healed after dressing change and skin grafting. The wounds in the flap donor and recipient sites healed well. During the postoperative follow-up of 6-24 months, the flaps had good texture and appearance with no new ulcers, and the patients had no obvious impairment in daily walk.Conclusions:The MDT cooperation model can sufficiently ensure the perioperative safety of DFU patients. The free anterolateral thigh perforator flaps can repair the DFU wounds achieving good clinical effects with high flap survival rate and decreased amputation rate.

Objective The risk evaluation indicators for the occurrence of diaphragm dysfunction in ICU patients was constructed to provide a reference for the establishment of the disease risk evaluation tools for diaphragm dysfunction.Methods The literature related to diaphragm dysfunction from CNKI,Wanfang Data,PubMed,Embase and Web of Science from the establishment of databases to November 11 th,2022 was systematically searched.After the first draft was determined through the literature review method,the first draft of the indicators was revised by brainstorming,with the opinions of 10 medical and nursing experts from May to June 2023.From June to July 2023,the content and weight of risk evaluation indicators of diaphragmatic dysfunction in ICU patients were determined through expert letter inquiry and hierarchical analysis.Results 35 experts completed the first round of letter inquiry,and 34 experts completed the second round of letter inquiry.The recovery rates of the valid questionnaires in the 2 rounds of expert correspondence were 92.1％and 97.1％,respectively,and the expert authority coefficients were 0.884 and 0.904,respectively,and the Kendall harmony coefficients of all indicators were 0.356～0.570 and 0.369～0.604,respectively(all P＜0.001).The final constructed risk evaluation indicators of diaphragm dysfunction in ICU patients includes 7 first-level indicators,34 secondary indicators and 34 tertiary indicators.Conclusion The risk evaluation index of diaphragm dysfunction in ICU patients constructed in this study is comprehensive,specific,scientific and applicable,which can guide medical staff to conduct early risk evaluation of diaphragm function in ICU patients,and provide references for the establishment of disease risk assessment tools for diaphragm function.

The aim of this study was to prepare a high drug-carrying capacity micellar drug delivery system(CTD@Sol)of the polymer zebra tetracycline and to preliminarily investigate the feasibility of this drug delivery system for the treatment of breast cancer.Firstly,CTD@Sol was prepared using sol as the carrier material and CTD as the model drug,and its pharmacological properties such as appearance and morphology,particle size,potential and in vitro release were evaluated.The growth inhibitory and apoptotic effects of CTD@Sol on breast cancer(4T1)cells were investigated by MTT assay and Annexin V-FITC/PI double staining assay;the uptake efficiency of 4T1 to this delivery system was investigated by flow cytometry;and the in vivo tissue distribution of the delivery system and the targeting of tumour tissues were investigated by small animal in vivo imaging technique.The results showed that CTD@Sol appeared as a light pale blue creamy white colour,with an average particle size of(159.73±1.96)nm,a PDI of 0.198±0.006,Zeta potential of-(47.60±1.77)mV,an encapsulation rate of(90.29±1.69)%and a drug loading capacity of(45.00±0.84)%;the in vitro release and haemolysis experiments showed that the drug release rate of CTD@Sol in acidic environment(pH 5.5)was significantly faster than that in neutral environment(pH 7.4),suggesting that the system is acid-sensitive and has good biosafety under endocytosed pH conditions.Cellular uptake,cytotoxicity and apoptosis experiments showed that CTD@Sol was more lethal to 4T1 cells,and the sol-gel polymer micelles as a drug delivery vehicle could significantly improve the cellular uptake efficiency of the drug;in vivo experiments showed that the delivery system had a significant targeting effect on tumour tissues.In conclusion,this study has successfully produced a CTD@Sol drug delivery system with high drug loading capacity(>45%),good pharmacological performance,strong targeting and biosafety,which has the potential to be used in the treatment of breast cancer.

Objective To construct a training program for retuming to work after delivery based on Morrison's job adaptation theory in operating room nurses and to explore its application effect.Methods On the basis of literature research and Delphi expert consultation method,a training program of postpartum return of operating room nurses was constructed.From August 2021 to December 2022,the preliminary application of this research program was carried out,with 6 cases in an experimental group and 5 cases in a control group.The differences between the 2 groups were compared by Job Adaptation Scale,Psychological Resilience Scale and satisfaction evaluation,and the application effect was evaluated.Results After 2 rounds of correspondence,a training program for postpartum return of operating room nurses was formed,which included 4 first-level indicators(role adaptation,task adaptation,environment adaptation and cultural adaptation),and 32 second-level indicators.The authority coefficients of the 2 rounds of correspondence consultation were 0.908 and 0.917,and the Kendall W coefficients were 0.224 and 0.206,respectively(both P＜0.001).The preliminary application results showed that there were statistically significant differences in job adaptation and satisfaction evaluation between the 2 groups(both P＜0.05).There was no significant difference in psychological resilience score between groups(P＞0.05).Conclusion The postpartum retum training program for operating room nurses established in this study is scientific and practical to a certain extent.In the future,samples can be expanded and multi-center studies can be carried out to further test the practicability and effectiveness of the program.

Objective:To investigate the clinical effect of free anterolateral thigh perforator flap(ALTPF) in reconstruction of temporal scalp defect after blood circulation reconstruction surgery for moyamoya disease.Methods:From May 2020 to July 2022, 7 patients with scalp defect after revascularisation of moyamoya disease were treated in Department of Hand and Foot Microsurgery, Henan Provincial People’s Hospital (People’s Hospital of Zhengzhou University). The patients were 4 males and 3 females, aged 33-59 years old, at 43 years old in average. There were 5 defects in left tempus and 2 in right tempus. The sizes of scalp defect were 4.5 cm × 5.5 cm-7.5 cm × 9.5 cm. Debridement and VSD management were primarily performed. After wounds were stabilised, ultrasound location of perforator vessels of ALTPFs was performed. Having confirmed that the perforator vessels were suitable for the surgical requirements, flap transfers were then performed. The descending branch of the lateral femoral circumflex artery was end-to-side anastomosed with the superficial temporal artery, and the descending branch of the lateral femoral circumflex vein was end-to-end anastomosed with the superficial temporal vein. Postoperative follow-up was conducted through outpatient clinic visits, telephone and WeChat reviews. Appearance, texture of ALTPFs and the flap donor sites were observed in follow-ups. Comparisons of the changes of nervous system before and after surgery were made. Cognitive function of the patients was assessed with the Mini Mental State Examination (MMSE), together with the Activities of Daily Living (ADL) .Results:All 7 flaps survived. One flap had vascular compromise 6 hours after surgery, and was rectified after surgical intervention. All the patients were included in the postoperative follow-up for 7-33 (average 19) months. All flaps had good appearance with soft texture. There was no obvious difference in colour comparing with the skin around the recipient region. The donor sites healed well without hypertrophic scar. Examinations of nervous system of the patients were found the same as that before surgery. Using Manual Muscle Testing (MMT), the average limb muscle strength of the patients was 4 before surgery and 4 after surgery, without change; Using the Ashworth assessment scale, the average preoperative and postoperative limb muscle tension in this group of patients was 1, without change; The Berg balance scale was used to evaluate the patient's balance function, with an average score of 42 before surgery and 42 after surgery, without any changes; There was no change in limb sensation before and after surgery; Using the MMSE, the average preoperative score and postoperative score of this group of patients were 25 points, without any change. Using the modified Barthel index scoring standard, the average preoperative score for this group of patients was 75 points, and the average postoperative score was 79 points, and the ADL of the patient had improved to various levels.Conclusion:Reconstruction of scalp defect with free ALTPF after revascularisation of moyamoya disease has obvious advantages, such as it closes the wound quickly, prevents infection and achieves a good appearance. This surgical procedure can produce a good clinical effect.

Objective:To investigate the association between metabolic syndrome and the risk of early renal function injury in chronic kidney disease(CKD) in the elderly.Methods:A retrospective cohort was established based on health check-up data of 4 495 elderly residents in Mengzi City, Yunnan Province from January 2016 to December 2018. The medial history, living habits, and related physical examination information were collected. Cox hazard regression model was used to explore the association between metabolic syndrome, along with its components, and the early renal function injury in CKD. Results:The median age of the elderly was 71.00(67.00, 75.00) years, with metabolic syndrome detection rate of 21.98%. Early renal function injury of CKD developed in 1 300(28.92%) subjects during the follow-up. Univariate Cox regression showed that the number of metabolic syndrome components was associated with the risk of early kidney development in CKD. The HRs were 1.23 (95% CI 1.03-1.47, P=0.022) with 1 component, 1.54 (95% CI 1.28-1.84, P<0.001) with 2, and 1.38 (95% CI 1.14-1.67, P<0.001) with 3 or more. Multivariate Cox regression showed that elevated fasting triglycerides( HR=1.20, 95% CI 1.07-1.36, P=0.003) and lower high density lipoprotein-cholesterol(HDL-C; HR=1.25, 95% CI 1.09-1.43, P=0.002) were risk factors for early kidney injury in CKD, while doing some physical activity( HR=0.57, 95% CI 0.33-0.98, P=0.042), or on daily basis( HR=0.57, 95% CI 0.49-0.66, P<0.001) was a protective factor for early kidney injury in CKD. Conclusion:The abnormality of one or more metabolic components can significantly increase the risk of early kidney injury in the elderly with CKD. Elevated triglyceride and decreased HDL-C may be the risk factors.

Objective: To search for specific metabolites in the lungs of pneumonia rats fed with a high-calorie diet, as well as explore the changes in the lung metabolites of young rats treated with Yinlai Decoction (YD) and its effects on inflammation-related metabolic pathways.Methods: Lipopolysaccharides (LPS) and a special high-calorie diet were used to induce Sprague Dawley (SD) rats to simulate the intestinal state of infant pneumonia. Liquid chromatography-mass spectrometry technology (LC-MS/MS) was used to detect metabolites in each group. Supervised orthogonal partial least squares discriminant analysis (OPLS-DA) model values were used for the detection results to find the differential metabolites. The metabolic pathways that are involved with the differential metabolites were clarified through enrichment analysis and topological analysis. Finally, the T cell receptor signaling pathway (TCR) signal conversion was analyzed by the network pharmacology method. Results: In the high-calorie diet combined with pneumonia group (M3), a total of 55 metabolites were determined to be different from the normal group (N). A total of 36 metabolites were determined to be different from those in the lung metabolites of the YD treatment group (T1). YD had a regulatory effect on glutathione metabolism, arginine and proline metabolism, ascorbic acid and aldehyde metabolism and phenylalanine metabolism. And the small molecule metabolites could act on the FYN and lymphocyte-specific protein tyrosine kinase (LCK) target proteins in the TCR signaling pathway, thereby affecting the immune function of the lungs. Conclusion: A high-calorie diet can cause abnormal sphingolipid metabolism in the lungs of young rats, thereby creating chronic lung inflammation in young rats. YD has a beneficial effect when used to treat young rats with LPS-induced pneumonia fed on high-calorie diets. Its mechanisms of action may affect the body's immune pathways by regulating the oxidative stress pathway affected by glutathione metabolism.

Objective:To investigate the safety and therapeutic effect of Shakubatrivalsartan in the treatment of pediatric dilated cardiomyopathy.Methods:Clinical information, treatment and prognosis of 5 cases with dilated cardiomyopathy in the First Affiliated Hospital of Xinxiang Medical University from June 2018 to December 2020 were retrospectively analyzed, and relevant literatures were reviewed.Results:A total of 5 cases of children with dilated cardiomyopathy were analyzed, including 3 males and 2 females with age of 12-17 years.Their median left ventricular ejection fraction (LVEF), left ventricular end diastolic dimension (LVDd), N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels were 37% (20%-41%), 61 mm (59-67 mm), and 13 250 ng/L (12 310-21 823 ng/L), respectively.The median conventional treatment time was 5 months (1-12 months), in which, the condition of heart failure gradually progressed, and the median LVEF, LVDd and NT-proBNP levels were reduced to 33% (19%-37%), 61 mm (60-74 mm), 13 144 ng/L (8 086-15 137 ng/L). After less than 3 months of follow-up following conventional treatment plus Shakubatrivalsartan, NT-proBNP level significantly decreased in 5 cases.Besides, 4 cases had improved cardiac function, and the other one′s improvement was not obvious.The blood pressure of 5 cases decreased at varying degrees after medication of Shakubatrivalsartan, which should be closely monitored during drug titration.No adverse reactions were reported.Conclusions:Shakubatrivalsartan for the treatment of pediatric dilated cardiomyopathy is safe and effective, which can alleviate or reverse the process of myocardial remodeling and improve cardiac ejection fraction, thus improving the prognosis.
