Following the principles of evidence-based medicine,in accordance with the structure and drafting rules of standardized documents,based on literature research,according to the characteristics of chronic cough in children and issues that need to form a consensus,the TCM Guidelines for Diagnosis and Treatment of Chronic Cough in Children was formulated based on the Delphi method,expert discussion meetings,and public solicitation of opinions.The guideline includes scope of application,terms and definitions,eti-ology and diagnosis,auxiliary examination,treatment,prevention and care.The aim is to clarify the optimal treatment plan of Chinese medicine in the diagnosis and treatment of this disease,and to provide guidance for improving the clinical diagnosis and treatment of chronic cough in children with Chinese medicine.

In Treatise on Cold Pathogenic and Miscellaneous Diseases,there are five articles concerning"diet as usual".When many doctors annotate such articles,they mostly interpret"diet as usual"as normal diet or because of stomach qi not affected by disease,ignoring the true significance of"diet as usual"and its role in clinical differential diagnosis.Through sorting out and summarizing the relevant provisions of"diet as usual",combining with the comments of Shuowen Jiezi and various ancient and modern doctors on the relevant provisions of"diet as usual"to explore the meaning behind it,the author believes that"diet as usual"can only be understood as"diet as before".Because it exists in a variety of diseases,it cannot be blindly extended to"normal diet"."Diet as usual"has two functions in clinical differential diagnosis:on the one hand,the stomach is empty,and no solid no drink blocks the qi movement,or there is stagnant heat in the stomach and intestines,but has not yet formed dry feces;on the other hand,when the middle jiao becomes one of the pathogenic factors of the disease,"diet as usual"can exclude the influence of the middle jiao.

Objective:To evaluate the efficacy and safety of Qingxuan Zhike granules in improving cough symptoms and shortening the course of influenza (wind-heat invading lung) in children.Methods:In this multicenter, randomized, controlled clinical trial, a total of 240 outpatient influenza patients from 7 hospitals, including the First Affiliated Hospital of Yunnan University of Traditional Chinese Medicine, from April 2023 to December 2023 were collected.The subjects were randomly divided into the control group and the experimental group via SAS software using the block randomization method.The differences between two groups were compared with t test, corrected t test and χ2 test.Subjects in the control group were given Oseltamivir phosphate granules, orally, twice a day (weight ≤15 kg, 30 mg/time; weight >15-23 kg, 45 mg/time; weight >23-40 kg, 60 mg/time; weight >40 kg, 75 mg/time; age≥13 years, 75 mg/time).In addition to Oseltamivir phosphate granules, subjects in the experimental group were also given Qingxuan Zhike granules, orally, 3 times a day (1-3 years old, 1/2 bag each time; >3-6 years old, 3/4 bag each time; >6-14 years old, 1 bag each time).After 5 days of treatment, the medication was suspended for 2 days.The effect of cough, antipyretic effect, clinical recovery rate, clinical recovery time, Canadian Acute Respiratory Illness and Flu Scale (CARIFS) score, traditional Chinese medicine (TCM) syndrome effect, complication rate, and adverse reactions were evaluated between the two groups. Results:Finally, 232 cases were included in the study, including 115 cases in the experimental group and 117 cases in the control group.Before and after treatment, there were no significant difference in CARIFS cough score between the experimental group and the control group (all P>0.05).After treatment, the change in CARIFS cough score in the experimental group [(-1.00±0.91) scores]was significantly higher than that in the control group [(-0.75±0.98) scores] ( t=-1.995, P=0.047).After treatment, the change in TCM syndrome cough score in the experimental group [(-1.69±1.51) scores] was significantly higher than that in the control group [(-0.97±1.63) scores] ( t′=-0.035, P=0.001).The time of complete regression of fever in the experimental group [(44.82±22.72) h] was shorter than that in the control group [(51.35±27.07) h], and the difference between the two groups was statistically significant ( t=-1.966, P=0.050).The fever score showed that the area under the curve between the CARIFS symptom fever score and time in the experimental group was 4.40±2.42, while that in the control group was 5.12±2.44, and the difference between the two groups was statistically significant ( t=-2.252, P=0.025).The clinical recovery rate was 93.91%(108/115) in the experimental group and 92.31%(108/117) in the control group, and there was no significant difference between the two groups ( χ2=0.233, P>0.05).The clinical recovery time in the experimental group [(2.93±1.21) d] was shorter than that in the control group [(3.29±1.15) d], and the difference between the two groups was statistically significant ( t=-2.279, P=0.024).After treatment, there was a significant difference in TCM syndrome score variation between the experimental group [(-12.00±4.13) scores] and the control group [(-10.85±4.31) scores] ( t′=-2.067, P=0.040).No complication occurred in both groups, and there was no significant difference in the incidence of adverse events between the two groups ( χ2=1.299, P>0.05). Conclusions:Qingxuan Zhike granules combined with Oseltamivir phosphate can effectively improve the cough symptoms associated with influenza in children, shorten the time and course of fever, and improve the TCM syndrome score; thus, they are safe in clinical application.

Objective To explore the patterns of functional gait asymmetry during the support phase and the differentiation of bilateral foot functions,to gain insights into the human movement compensa-tion mechanisms and stability control characteristics,so as to provide theoretical references for the pre-vention and rehabilitation treatment of unilateral foot and ankle injuries.Methods Twelve young females with normal feet were recruited,and the time percentage of each phase of the support period,the change of longitudinal arch angle,the vertical ground reaction force and the center of plantar pressure trajectory of the dominant and non-dominant feet were collected by using a three-dimensional motion capture and a high-frequency plantar pressure testing system when the subjects walked at the optimum speed with the incremental loading of weights[0%body weight(BW),10%BW and 20%BW].The ef-fects of laterality(dominant foot,non-dominant foot)and load(0%BW,10%BW,20%BW)on arch changes and gait parameters,and the interactions between them,were analyzed using a two-way re-peated-measures ANOVA.Results The factors of laterality and load interacted significantly on arch changes,but not on gait parameters.(2)Compared with 0%BW,the time percentage of the buffering phase of the nondominant feet with the load of 20%BW increased(P<0.05),while that of the domi-nant ones decreased(P<0.05),with an increase in the buffering load of both feet with the load of 20%BW(P<0.05)and the buffering force excursion of both feet with the load of 10%BW(P<0.05).More-over,changes in longitudinal arch angle increased(P<0.05)with the load of 10%and 20%BW,the pedal extension load rate increased(P<0.05)with the above BW load in the non-dominant feet,and the horizontal slope of pedal extension decreased(P<0.05)with 20%BW load in the dominant feet.Compared with 10%BW,when the feed was loaded 20%BW,the time percentage in the buffering phase and the buffering force offset of the dominant feet decreased(P<0.05),while the buffering load of both feet increased(P<0.05).(3)Compared with the non-dominant feet,for the dominant feet,the buffering load rate at the load of 10%and 20%BW and changes in the longitudinal arch angle at the load of 20%BW decreased(P<0.05),while the horizontal slope of the pedal extension without load in-creased(P<0.05).Conclusion Walking with load induces function differentiation in bilateral feet.The dominant foot has more efficient horizontal extension without load and better buffering function in the vertical direction with loads,while the non-dominant feet perform a more adequate weight-bearing and extension function vertically with larger load.It is suggested that unilateral injury feet should not be given too much load,and it is inappropriate to select a single foot to represent and evaluate the func-tion and injury risk of the double feet in loaded walking.

Objective:To study the learning curve of percutaneous patent foramen ovale (PFO) occlusion guided solely by transthoracic echocardiography (TTE), as well as the success rate and safety of the learning curve.Methods:To retrospectively analyze these patients with indications for PFO occlusion admitted in our department from April 2021 to April 2022, and obtained 100 samples the author's initial cases guided solely by TTE, including 25 men and 75 women, with a mean age of (48.22±10.44) years old.Analyze preoperative baseline data: gender, age, height, weight, body mass index, the tunnel length and size of the PFO measured by transesophageal echocardiography, the grade of contrast-transcranial doppler test, combined atrial septal aneurysm, etc.Operation time, success rate, and complications were analyzed in all patients.Results:With the accumulation of cases, the operation time gradually shortened, accumulated to about 50 cases, the operation time has significantly shortened ( P<0.05), and the learning curve was leveled off after 50 cases ( P<0.05), there was statistical difference.The comparison of the success rate and complication of cases within the learning curve and those after completing the learning curve was no statistical significance( P>0.05). Conclusion:The learning curve of percutaneousc closure of patent foramen ovale guided solely by TTE is long, requiring about 50 cases to complete the learning curve. The success rate and safety of the learning curve are high. This procedure is worth popularizing.

Objective:This study aimed to investigate the risk features of postoperative tumor recurrence of medullary thyroid carcinoma.Methods:One hundred and seventy two patients with medullary thyroid carcinoma diagnosed at Tianjin Cancer Hospital between Jan 2010 and Jan 2018 were enrolled in this study. Based on the follow-up results, patients were divided into tumor recurrence and non-tumor recurrence group. US features,clinicopathological characteristics and somatic RET mutations were evaluated between the two groups. The cut-off values of pre-and post-operative serum calcitonin were calculated by ROC curve.Univariate and multivariate analysis were adopted between the two groups to determine independent risk factors for tumor recurrence of MTC.Tumor-free survival was determined by Kaplan-Meier analysis.Results:Univariate analysis showed that preoperative serum calcitonin≥1 367 pg/ml ( χ2=18.909, P=0.000), postoperative serum calcitonin ≥61 pg/ml ( χ2=72.278, P=0.000), mulifocality ( χ2=11.787, P=0.001),lesions in both lobes ( χ2=10.452, P=0.003), extrathyroidal invasion ( χ2=14.511, P=0.000), T3+T4-staging ( χ2=11.920, P=0.001)、TNMⅢ+Ⅳ-staging ( χ2=18.915, P=0.000), ACR TI-RADS 5 ( χ2=7.162, P=0.006) and RET mutation ( χ2=10.937, P=0.001) were significantly related to tumor recurrence of medullary thyroid carcinoma. Multivariate analysis demonstrated that postoperative serum calcitonin≥61 pg/ml ( OR=22.323, 95%CI: 6.370-78.236) and RET mutation ( OR=4.054, 95%CI: 1.354-12.139) were the independent factors related to tumor recurrence of medullary thyroid carcinoma.The survival curves of MTC patients showed a significantly lower percentage of surviving patients in the group with postoperative serum calcitonin ≥61 pg/ml ( P=0.000) or RET mutations ( P=0.001). Conclusions:Postoperative serum calcitonin ≥61 pg/ml and oncogenic RET mutation were the independent risk factors for tumor recurrence of MTC.Patients with postoperative serum calcitonin ≥61 pg/ml or a RET mutation tended to have a shorter tumor-free survival.

Objective To investigate the distribution and drug resistance characteristics of pathogens in donors and recipients undergoing simultaneous pancreas-kidney transplantation (SPK). Methods Clinical data of 231 pairs of donors and recipients undergoing SPK were analyzed retrospectively. The pathogens of samples from donors and recipients were identified by VITEK-2 analyzer, and drug sensitivity test was performed by K-B method. The source distribution and composition ratio of pathogens in donor and recipient samples, distribution characteristics of multi-drug resistant organism, infection of recipients and drug resistance characteristics of pathogens were analyzed. Results A total of 395 strains of pathogens were cultured from 1 294 donor samples, and the detection rate was 30.53%. Gram-negative bacteria mainly consisted of klebsiella pneumoniae, Gram-positive bacteria mainly comprised staphylococcus aureus, and fungi primarily included candida albicans, respectively. In total, 2 690 strains of pathogens were cultured from 10 507 recipient samples, and the detection rate was 25.60%. Gram-negative bacteria mainly consisted of pseudomonas maltophilia, Gram-positive bacteria primarily comprised enterococcus faecalis, and fungi mainly included candida albicans, respectively. Among 395 pathogens of donors, 15 strains of methicillin-resistant staphylococcus aureus (MRSA), 16 strains of extended-spectrum β-lactamase (ESBL) positive drug-resistant bacteria, 8 strains of carbapenem-resistant pseudomonas aeruginosa (CR-PA), 21 strains of carbapenem-resistant acinetobacter baumannii (CR-AB), 2 strains of carbapenem-resistant enterobacteriaceae (CRE) and 1 strain of multiple-drug/pan-drug resistant pseudomonas aeruginosa (MDR/PDR-PA) were identified. Among 2 690 strains of recipient pathogens, 73 strains of ESBL positive drug-resistant bacteria, 44 strains of CR-PA, 31 strains of CR-AB and 3 strains of MDR/PDR-PA were detected. One recipient developed donor-derived infection, 69 cases of pneumonia, 52 cases of urinary tract infection, 35 cases of abdominal infection and 2 cases of hematogenous infection were reported within postoperative 1 year. Gram-negative bacteria were resistant to certain antibiotics. Gram-positive bacteria were sensitive to vancomycin. Fungi were sensitive to amphotericin B. Conclusions Gram-negative bacteria are the main pathogens of SPK recipients, which are resistant to certain antibiotics. Empirical use of antibiotics can be delivered before culture results are obtained. Subsequently, sensitive antibiotics should be chosen according to the culture results to improve the survival rate of SPK recipients.

Purpose: This study was performed to investigate the association of Glasgow prognostic score (GPS), combined positive score (CPS), and clinicopathological characteristics of locally advanced rectal cancer. Methods: Between February 2012 and February 2018, 103 patients with locally advanced rectal cancer treated by neoadjuvant chemoradiotherapy and total mesorectal excision (TME) were retrospectively evaluated. Results: According to the classification of the GPS, 85 (82.5%), 13 (12.6%), and 5 patients (4.9%) were classified as a score of 0, 1, and 2, respectively. Patients were classified into the GPS-low group (GPS of 0, n = 85) and GPS-high group (GPS of 1 or 2, n = 18) with an area under the curve of 0.582 for overall survival (OS). The mean programmed death-ligand 1 (PD-L1) CPS of the whole group was 2.24 (range, 0–70). The PD-L1 CPS of the GPS-high group was higher than the GPS-low group (P < 0.001). Multivariate analysis by Cox proportional hazards model indicated that GPS was associated with OS and diseasefree survival (DFS). Furthermore, PD-L1 CPS was associated with DFS (hazard ratio, 1.050; 95% confidence interval, 1.017– 1.083; P = 0.003). Conclusion Elevated GPS was related to the PD-L1 CPS. GPS and PD-L1 CPS were associated with the prognosis of locally advanced rectal cancer treated with neoadjuvant chemoradiotherapy followed by TME.

The tumors of central nervous system refer to a group of benign and malignant diseases originating from tissues or structures within the central nervous system. Common tumors of central nervous system are sporadic, but a few have familial onset. Compared with sporadic brain tumors, the clinical symptoms, diagnostic ideas and follow-up review plans of familial brain tumors are more complicated. The multidisciplinary diagnosis and treatment (MDT) mode usually refers to a treatment mode in which a case involving multiple organs and systems is discussed, and the best treatment plan is formulated for the patient based on the comprehensive opinions of various disciplines. Because familial brain tumors often involve multiple organs, multiple disciplines and multiple systems, and their low incidence leads to less clinical experience for neurosurgeons, the MDT model is more conducive to efficient diagnosis, treatment and management of familial brain tumors. This review elaborates on the neurosurgeon-led MDT model, and introduces the latest research on the epidemiology, genetic characteristics, clinical manifestations, diagnostic ideas and multidisciplinary management of familial brain tumors.

Objective To analyze the risk factors for the occurrence of post transplantation diabetes mellitus (PTDM) in renal transplant recipients, establish a prediction model for PTDM and evaluate its prediction value. Methods Clinical data of 915 renal transplant recipients were retrospectively analyzed. According to the occurrence of PTDM, all recipients were divided into the PTDM group (n=78) and non-PTDM group (n=837). The main indexes of recipients were collected. The risk factors for the occurrence of PTDM in renal transplant recipients were analyzed by univariate and multivariate analysis. The prediction model for PTDM was established and its prediction value was evaluated. Results Family history of diabetes mellitus, body mass index (BMI), preoperative 2 h postprandial blood glucose and preoperative glycosylated hemoglobin were the independent risk factors for the occurrence of PTDM in renal transplant recipients. The prediction model for PTDM was logit (P)=2.199×family history of diabetes (yes=1, no=0)+0.109×BMI+0.151×2 h postprandial blood glucose (mmol/L)+0.508×glycosylated hemoglobin (%)-9.123. The results of receiver operating characteristic (ROC) curve showed that the area under the curve (AUC) of these 4 predictors combined for predicting PTDM in renal transplant recipients was 0.830 [95% confidence interval (CI) 0.786-0.873], the cut-off value was 0.0608, the sensitivity was 0.821, the specificity was 0.700, and the Youden index was 0.521 (P < 0.05). Conclusions Family history of diabetes mellitus, BMI, preoperative 2 h postprandial blood glucose and preoperative glycosylated hemoglobin are the independent risk factors for the occurrence of PTDM in renal transplant recipients. The prediction model for PTDM combined with4 predictors yield relatively high prediction value for PTDM.
