From the perspective of the physiological basis of liver and kidney sharing the common source in traditional Chinese medicine(TCM),and by integrating the theory of kidney dominating bone,liver dominating tendon,and meridian sinew of TCM as well as the bone resorption and collapse theory,and non-uniform settlement theory and lower-limb musculoskeletal bowstring structure theory of modern orthopedics,the pathogenesis of osteonecrosis of the femoral head(ONFH)under the system of non-uniform settlement during bone resorption and multidimensional composite bowstring working in coordination with the theory of liver-kidney and muscle-bone was explored.The key to the TCM pathogenesis of ONFH lies in the deficiency of the liver and kidney,and then the imbalance of kidney yin-yang leads to the disruption of the dynamic balance of bone formation and bone resorption mediated by osteoblasts-osteoclasts,which manifests as the elevated level of bone metabolism and the enhancement of focal bone resorption in the femoral head,and then leads to the necrosis and collapse of the femoral head.It is considered that the kidney dominates bone,liver dominates tendon,and the tendon and bone together constitute the muscle-bone-joint dynamic and static system of the hip joint.The appearance of collapse destroys the originally balanced muscle-bone-joint system.Moreover,the failure of liver blood in the nourishment of muscles and tendons further exacerbates the imbalance of the soft tissues around the hip joint,accelerates the collapse of the muscle-bone-joint dynamic and static system,speeds up the process of femoral head collapse,and ultimately results in irreversible outcomes.Based on the above pathogenesis,the systematic integrative treatment of ONFH should be based on the TCM holistic concept,focuses on the focal improvement of internal and external blood circulation of the femoral head by various approaches,so as to rebuild the coordination of joint function.Moreover,attention should be paid to the physical constitution of the patients,and therapy of tonifying the kidney and regulating the liver can be used to restore the balance between osteogenesis and osteoblastogenesis,and to reconstruct the muscle-bone-joint system,so as to effectively delay or even prevent the occurrence of ONFH.

AIM To explore the clinical effects of Danzhi Xiaoyao Powder combined with Hetiao Duren Anshen Acupuncture Method on patients with post-stroke depression.METHODS Ninety-eight patients were randomly assigned into control group(49 cases)for 4-week intervention of conventional treatment,and observation group(49 cases)for 4-week intervention of Danzhi Xiaoyao Powder,Hetiao Duren Anshen Acupuncture Method and conventional treatment.The changes in clinical effects,MoCA score,intestinal flora(Enterococcus,Lactobacillus,Escherichia coli,Bifidobacterium),immune function indices(IgM,IgG,IgA),depression status indices(HAMD score,SDS score)and incidence of adverse reactions were detected.RESULTS The observation group demonstrated higher total effective rate than the control group(P＜0.05).After the treatment,the two groups displayed increased MoCA score,immune function indices(P＜0.05),decreased HAMD score,SDS score(P＜0.05),reduced Enterococcus,Escherichia coli(P＜0.05),and elevated Lactobacillus,Bifidobacterium(P＜0.05),especially for the observation group(P＜0.05).No significant difference in incidence of adverse reactions was found between the two groups(P＞0.05).CONCLUSION For the patients with post-stroke depression,Danzhi Xiaoyao Powder combined with Hetiao Duren Anshen Acupuncture Method can safely and effectively improve cognitive functions,humoral immunities,regulate intestinal flora,and alleviate depression symptoms.

This study aimed to evaluate the efficacy and safety of Chaihuang Granules in the treatment of upper respiratory tract infection in children. The databases such as CNKI, Wanfang, VIP, SinoMed, Cochrane Library, PubMed, EMbase, Web of Science, Chinese Clinical Trial Registry, and ClinicalTrials.gov were searched for randomized controlled trial(RCT) of Chaihuang Granules for the treatment of upper respiratory tract infection in children, and supplemented by manual searching of gray literature. Two investigators independently screened the literature, extracted data, and assessed the methodological quality. Meta-analysis was performed using RevMan 5.4 software, trial sequential analysis was conducted using TSA 0.9.5.10 Beta software, and evidence quality evaluation was carried out using GRADE profiler 3.6.1 software. Eighteen RCTs involving 2 459 patients(1 262 in the treatment group and 1 197 in the control group) were included. Meta-analysis showed that compared with conventional therapy alone, Chaihuang Granules significantly improved the total effective rate(RR=1.18, 95%CI[1.15, 1.22], P<0.000 01), reduced the disappearance time of symptoms/signs(MD=-1.39, 95%CI[-1.66,-1.12], P<0.000 01), improved cytokine levels(MD=-2.40, 95%CI[-3.80,-1.00], P=0.000 8), improved humoral immune levels(MD=0.75, 95%CI[0.60, 0.90], P<0.000 01), and reduced the recurrence rate(MD=-2.11, 95%CI[-2.98,-1.25], P<0.000 01). However, the incidence of adverse reactions was not increased(RR=0.94, 95%CI[0.59, 1.49], P=0.78). Subgroup analysis showed that:(1) both Chaihuang Granules used alone(RR=1.19, 95%CI[1.11, 1.27], P<0.000 01) and in combination with other therapies(RR=1.18, 95%CI[1.14, 1.22], P<0.000 01) effectively improved the total effective rate.(2) In terms of symptoms/signs disappearance time, Chaihuang Granules effectively reduced the duration of fever(MD=-1.18, 95%CI[-1.78,-0.58], P=0.000 1), cough with sputum(MD=-1.82, 95%CI[-2.38,-1.25], P<0.000 01), cough(MD=-1.31, 95%CI[-1.89,-0.74], P<0.000 01), sore throat(MD=-1.57, 95%CI[-2.25,-0.89], P<0.000 01), and lung rales(MD=-1.49, 95%CI[-2.06,-0.92], P<0.000 01).(3) Regarding cytokine levels, Chaihuang Gra-nules effectively improved the levels of interleukin(IL)-2(MD=-0.94, 95%CI[-1.16,-0.72], P<0.000 01), IL-6(MD=-4.71, 95%CI[-6.39,-3.03], P<0.000 01), and tumor necrosis factor-α(TNF-α)(MD=-2.07, 95%CI[-2.43,-1.71], P<0.000 01).(4) In terms of cellular immune levels, Chaihuang Granules effectively improved the levels of CD3~+(MD=4.11, 95%CI[1.53, 6.69], P=0.002), CD4~+(MD=4.21, 95%CI[1.69, 6.73], P=0.001), CD8~+(MD=-2.65, 95%CI[-3.93,-1.37], P<0.000 1), and CD4~+/CD8~+(MD=0.25, 95%CI[0.14, 0.37], P<0.000 1).(5) In terms of humoral immune levels, Chaihuang Granules effectively improved the levels of IgA(MD=0.44, 95%CI[0.23, 0.64], P<0.000 1), IgM(MD=0.31, 95%CI[0.15, 0.46], P=0.000 1), and IgG(MD=2.02, 95%CI[1.60, 2.43], P<0.000 01). Trial sequential analysis showed that the cumulative Z-curve of the total effective rate crossed the boundary value, further confirming its clinical efficacy. The GRADE evidence quality evaluation showed that the evidence quality of the above outcome indicators was low or very low, and the recommendation strength was weak. Compared to conventional therapy alone, Chaihuang Granules can effectively improve the total effective rate of treatment, alle-viate symptoms and signs of upper respiratory tract infection in children, improve inflammatory conditions, enhance immune function, and reduce the recurrence rate. Due to the limited quality of the included studies, high-quality RCT is still needed to provide evidence support for the above conclusions.

This study aims to evaluate the efficacy and safety of Compound Qinlan Oral Liquid in the treatment of acute upper respiratory tract infection. Computer-based online searching of CNKI, VIP, SinoMed, Wanfang, ChiCTR, ClinicalTrials.gov, Cochrane Library, PubMed, EMbase, and Web of Science was performed to retrieve the randomized controlled trial(RCT) regarding Compound Qinlan Oral Liquid in the treatment of acute upper respiratory tract infection. In addition, manual searching of gray literature was conducted. After two evaluators independently selected articles, extracted data, and evaluated the quality of methodology included in the studies, Meta-analysis was carried out in RevMan 5.4 and trial sequential analysis(TSA) in TSA 0.9.5.10 Beta. GRADE profiler 3.6.1 was employed to evaluate the evidence quality. A total of 21 RCTs were included in this study, involving 2 651 patients(1 330 patients in the observation group and 1 321 patients in the control group). Meta-analysis showed that compared with conventional western medicine alone, Compound Qinlan Oral liquid improved the total response rate(RR=1.15, 95%CI[1.12, 1.19], P<0.000 01) without increasing the incidence of adverse reactions(RR=0.77, 95%CI[0.47, 1.25], P=0.16). The results of subgroup analysis are described as follows:(1) Compared with conventional western medicine alone, Compound Qinlan Oral Liquid improved the total response rate(RR=1.10, 95%CI[1.05, 1.14], P<0.000 01) and shortened the time to symptom relief(SMD=-0.76, 95%CI[-1.02,-0.51], P<0.000 01). There was no significant difference in the incidence of adverse reactions between the two groups(RR=1.16, 95%CI[0.54, 2.47], P=0.71).(2) Compared with conventional western medicine alone, Compound Qinlan Oral Liquid + conventional western medicine improved the total response rate(RR=1.20, 95%CI[1.15, 1.25], P<0.000 01), decreased traditional Chinese medicine(TCM) syndrome scores(MD=-0.58, 95%CI[-0.75,-0.41], P<0.000 01), shortened the time to symptom relief(SMD=-2.44, 95%CI[-3.09,-1.80], P<0.000 01) and physical sign improvement(MD=-2.57, 95%CI[-4.11,-1.04], P=0.001), lowered the serum levels of inflammatory cytokines(SMD=-2.16, 95%CI[-2.61,-1.70], P<0.000 01), improved respiratory function indicators(SMD=1.48, 95%CI[1.00, 1.96], P<0.000 01), and enhanced the humoral immunity(MD=0.94, 95%CI[0.69, 1.18], P<0.000 01). There was no significant difference in the incidence of adverse reactions between the two groups(RR=0.57, 95%CI[0.29, 1.09], P=0.09). TSA showed that the cumulative Z curve of total response rate crossed the traditional threshold and TSA threshold, further confirming the clinical efficacy of Compound Qinlan Oral Liquid. The GRADE graded the evidence of the above outcome indicators as low or extremely low, and yielded weak recommendation. Compared with conventional western medicine alone, Compound Qinlan Oral Liquid can improve the total effective rate and reduce the time to symptom relief. The combination of Compound Qinlan Oral Liquid and conventional western medicine can improve the total response rate, mitigate the symptoms and improve the physical signs, reduce inflammation, and improve respiratory function and immunity of the patients with acute upper respiratory tract infection. In view of the limited number and quality of the included studies, the above conclusions still require high-quality RCT to provide evidence support.

Objective To investigate the EMG characteristics and clinical application value of surface EMG in cervical muscle group of children with congenital muscular torticollis(CMT).Methods A retrospective analysis was performed on 478 children diagnosed as CMT from January 2018 to August 2022 in Rehabilitation Center of the Children's Hospital Affiliated to Chongqing Medical University.The torticollis side of the same case was included in observation group and the healthy side was included in control group.Surface EMG was used to record the electromyography root-mean-square values of bilateral sternocleidomastoid muscles,platysma muscles and upper trapezius muscles in the rest and different exercise states.The difference of root-mean-square values between the affected side and the healthy side muscle groups at rest and under different exercise states and the diagnostic value were compared.Spearman correlation analysis was used to evaluate the relationship between the severity of congenital muscular torticollis on the affected side and the root mean square value of each cervical muscle group.Results The root-mean-square value of sternocleidomastoid muscle on the affected side of CMT children was higher than that on the healthy side during relaxation and lower than that on the healthy side during contraction,and the differences were statistically significant(P<0.05),the abnormal root-mean-square value of the affected side in the resting position and in all motion state has higher diagnostic value.The root-mean-square value of platysma muscle on the affected side was higher than that on the healthy side when it was in the resting position and the reverse neck rotation relaxed state(P<0.05),and lower than that on the healthy side when it was in the same neck rotation contraction state(P<0.05),abnormal values detected in resting sitting position and elevation of head have higher value.Root-mean-square value of upper trapezius muscle on the affected side was higher than that on the healthy side in the relaxed state(P<0.05).The abnormal values in sitting position,turning neck and bending head have high diagnostic value.The severity of CMT was positively correlated with the root-mean-square values of sternocleidomastoid muscle,platysma muscle,and upper trapezius muscle(r was 0.721,0.612,0.655,P<0.001).Conclusion sEMG could be used as a good method for the clinical diagnosis and evaluation of congenital muscular torticollis in children.

Objective: To investigate the outcomes including major complications and prognosis of extremely preterm infants with gestational age ≤25⁺⁶ weeks. Methods: The cross-sectional study enrolled 233 extremely preterm infants with gestational age ≤25⁺⁶ weeks who were admitted to the Department of Neonatology of Shenzhen Maternity and Child Healthcare Hospital from January 2015 to December 2021. The clinical data including perinatal factors, treatments, complications, and prognosis were extracted and analyzed. These extremely preterm infants were also grouped according to gestational age and year of admission to further analyze their survival rate, major complications, causes of death, and long-term outcomes. The comparisons between the groups were performed with Chi-square test and Kruskal-Wallis. Results: Among these 233 extremely preterm infants, 134 (57.5%) were males and 99 (42.5%) females. The gestational age was (24.6±0.9) weeks, the birth weight was 710.0 (605.0,784.5) g, and the overall survival rate was 61.8% (144/233). Among the surviving extremely preterm infants, the earliest gestational age was 22⁺² weeks and the lowest birth weight was 390 g. There were 17.6% (41/233) of extremely preterm infants had treatment withdrawn and were discharged in line with the will of guardians. Among the rest 192 extremely preterm infants managed with aggressive treatments, 14 (7.3%) died in hospital and 34 (17.7%) had treatment withdrawn later due to severe complications. Of the 192 extremely preterm infants, 144 (75.0%) survived, and the survival rate increased year by year (χ²=26.28, P<0.001) while the mortality decreased year by year (χ²=14.09, P=0.027). Among the survivors, 20.8%(30/144) had no major complications, and the incidence of complications was also negatively related with the gestational age (χ²=7.24, P=0.044), and the length of invasive ventilation was negatively related to the gestational age (χ²=29.14, P<0.001). In the group of less than 23⁺⁶ weeks, all extremely preterm infants had one or more major complications. The follow-up were completed in 122 infants and revealed that delayed motor development, language retardation, and hearing and vision impairment accounted for 17.2% (21/122), 8.2% (10/122) and 17.2% (21/122), respectively. Conclusions: Extremely preterm infants with gestational age ≤25⁺⁶ weeks are difficult to treat, but the survival rate of infants undergoing aggressive treatments increases year by year. Although the prevalence of major complications is still high, most extremely preterm infants have acceptable prognosis during follow-up.

OBJECTIVE: To evaluate the impact of a history of vaginal delivery on anesthesia management of patients undergoing hysteroscopic surgery under intravenous general anesthesia without tracheal intubation. METHODS: Ninety-nine patients undergoing hysteroscopic surgery under intravenous general anesthesia were enrolled in this study, including 43 patients with (VD group) and 56 patients without a history of vaginal delivery (NVD group). For all the patients, blood pressure, heart rate (HR), blood oxygen saturation (SpO₂) and bispectral index (BIS) were recorded before anesthesia (T1), after anesthesia (T2), after cervical dilation (T3), and at 3 min after cervical dilation (T4). Propofol and etomidate doses during anesthesia induction, the total dose of propofol administered, additional intraoperative bolus dose and times of propofol, intraoperative body movement, total operation time and surgeons' satisfaction feedback scores were compared between the two groups. The postoperative awake time, recovery time, VAS score at 30 min after operation, and postoperative nausea and vomiting (PONV) were also compared. RESULTS: There was no significant differences in SBP, DBP, HR, SpO₂, or BIS between the two groups at T1 and T2, but at T3 and T4, SBP and DBP were significantly higher in NVD group than in VD group (P < 0.01); HR was significantly higher in NVD group only at T3 (P < 0.01). The application of vasoactive drugs did not differ significantly between the two groups. The total dose of propofol, additional intraoperative dose and times of propofol were all greater in NVD group than in VD group (P < 0.01). More body movements of the patients were observed in NVD group (P < 0.01), which also had lower surgeons' satisfaction score for anesthesia (P < 0.01), higher postoperative VAS score (P < 0.05), and shorter postoperative awake time (P < 0.05) and recovery time (P < 0.01). CONCLUSION A history of vaginal delivery has a significant impact on anesthesia management of patients undergoing hysteroscopic surgery under intravenous general anesthesia without tracheal intubation in terms of hemodynamic changes, anesthetic medication, and postoperative recovery quality, suggesting the necessity of individualized anesthesia management for these patients.

ObjectiveTo explore the underlying molecular mechanism of Xiaochuanning granules in the treatment of bronchial asthma based on the network pharmacology and experimental verification through the phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt） signaling pathway on ovalbumin （OVA） sensitization-induced bronchial asthma model in rats. MethodThe main active ingredients and targets of Xiaochuanning Granules were screened out from Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP） and Bioinformatics Analysis Tool for Molecular Mechanism of Traditional Chinese Medicine （BATMAN-TCM）. The targets related to bronchial asthma were obtained from five disease databases such as GeneCards and Online Mendelian Inheritance in Man （OMIM）. The common targets were screened out through the Venn diagram. STRING was used to construct the protein-protein interaction （PPI） network of "compound-disease"， and Cytoscape 3.8.0 was used to establish a network of key active ingredients of Xiaochuanning granules and core target genes （"ingredient-gene" network）. Gene Ontology （GO） and Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment analyses were performed through DAVID. The bronchial asthma model was induced by OVA stimulation in rats. Bronchial and lung tissue inflammation was observed by hematoxylin-eosin （HE） staining， and the enrichment analysis results of the network pharmacology were verified by Western blot. ResultIn this experiment， 232 active ingredients and 4 687 related targets of Xiaochuanning granules were screened out， and 233 common targets of Xiaochuanning granules and bronchial asthma were collected， including eosinophil-derived neurotoxin 1 （EDN1）， cyclic AMP response element-binding protein 1 （CREB1）， cyclin-dependent kinase inhibitor 1A （CDKN1A）， epidermal growth factor receptor （EGFR）， mitogen-activated protein kinase 14 （MAPK14）， and Akt1. KEGG pathway analysis revealed 186 related signaling pathways， indicating that the PI3K/Akt signaling pathway presumedly played a key role in the treatment of bronchial asthma by Xiaochuanning granules. The animal experiment showed that Xiaochuanning granules relieved the airway inflammation and smooth muscle hyperplasia in rats and down-regulated the gene expression of PI3K and Akt as compared with the conditions in the model group （P<0.05）. ConclusionXiaochuanning granules have the characteristics of multi-component， multi-target， and multi-pathway synergistic effect in the treatment of asthma. Xiaochuanning granules may exert anti-inflammatory effects by regulating the expression of genes related to the PI3K/Akt signaling pathway. The present study is expected to provide a theoretical basis for follow-up in-depth research on the complex mechanism of Xiaochuanning granules in the treatment of bronchial asthma.

Objective:To investigate the clinical efficacy of conservative and surgical treatment of testicular appendage torsion in children and to summarize the experience.Methods:The clinical data of 106 children with testicular appendage torsion admitted in Tengzhou Central People's Hospital Affiliated to Xuzhou Medical University from January 2012 to December 2018 were retrospectively analyzed. According to different therapeutic methods, all the children were divided into conservative group (25 cases) and surgical group (81 cases). The clinical efficacy was compared between the two groups.Results:106 children with testicular appendage torsion were cured. The hospitalization time [(5.61±1.04)d vs (11.32±1.89)d], pain relief time [(9.11±2.56)d vs (68.5±19.87)d], disappearance time of scrotal edema [(5.11±1.08)d vs (10.56±1.50)d] and the utility time of antibiotic [(4.89±1.32)d vs (7.06±1.26)d] in the surgical group were shorter than those in the conservative group, with statistically significant difference(all P<0.05). After 6 months of follow-up, there were no cases of recurrence and discomfort in the two groups. Conclusions:Children with testicular appendage torsion should be actively treated with surgery, which can not only significantly shorten the course of disease, but also reduce the incidence of complications and missed diagnosis. For children who with testicular appendage torsion, surgeries should be performed actively. It can significantly shorten the duration of symptoms, but also reduce the occurrence of complication and the occurrence probability of misdiagnosis.

During fluorescence-guided cancer surgery, ultra-pH sensitive (UPS) fluorescent nanoprobes has multiple advantages such as real-time imaging procedures, ultra-high imaging sensitivity as well as broad tumor detection specificity. UPS nanoprobes stay at "OFF" state at higher pH and turn into "ON" state at lower pH with emission of strong fluorescence. Moreover, the transition pH points (transition pH point, pH_t) can be precisely controlled by structural-based strategy. One of the previously-reported UPS nanoprobes showed good imaging effect. However, it is still not clear about the effect of pH_t on cancer imaging efficiency of UPS nanoprobes and to further identify the optimal UPS. In this study, we synthesized a series of UPS nanoprobes with pH_t at 4.5, 6.2, 6.6, 7.8 by adjusting the hydrophobic blocks of UPS polymers. Each nanoprobe showed excellent stability in "OFF" state by dynamic light scattering and uniform morphology observed by transmission electron microscopy. In vitro imaging characterized the ultra-pH sensitive fluorescence transition of each probe. In vivo imaging results identified two UPS nanoprobes (NP-6.2 and NP-6.6) with superior tumor imaging effect. All animal experiments in this study were approved by the Animal Ethics Committee of Peking University Health Science Center and were strictly followed by the welfare regulations of laboratory animals of Peking University Health Science Center. Therefore, this study has explored the effect of pH_t on the cancer imaging efficiency of UPS nanoprobes and provides a new idea for design of the other cancer microenvironment-responsive polymers.
