OBJECTIVE To evaluate the quality of diagnosis and treatment guidelines and expert consensuses on childhood immune thrombocytopenic purpura （ITP） published domestically and internationally， in order to provide reference for clinical practice and future guideline/expert consensus development and improvement. METHODS A systematic search was conducted across multiple databases， including PubMed， Cochrane Library， Embase， CNKI， Wanfang data， VIP， CBM； additionally， supplementary searches were carried out on websites such as Medlive， the Chinese Medical Association’s official website， and National Institute for Health and Clinical Excellence in the UK. The retrieval time ranged from the inception to September 2， 2024. Researchers who had undergone systematic training independently evaluated the methodology and report quality included in the guideline/consensus using the Appraisal of Guidelines Research and Evaluation Ⅱ （AGREE Ⅱ） and the Reporting Items for Practice Guidelines in Healthcare （RIGHT）. RESULTS A total of 11 guidelines/consensuses were included. The average scores for the six domains of AGREE Ⅱ tool respectively were “range and purpose” （[ 66.67±17.98）% ]， “participants” [58.33% （13.89%，73.61%）]， “rigor” （[ 41.81±23.85）% ]， “clarity”（[ 69.57±19.35）%]， “applicability” （[ 35.98±17.83）%]， and “independence” [27.08% （0，75.00%）]； out of 11 articles， 9 had a recommendation level of B， 2 had a recommendation level of C， and there were no A-level articles. The average reporting rates of the 7 areas in the RIGHT tool were “basic information” （[ 72.35±12.95）% ]， “background” （[ 54.55±15.40）%]，“ evidence” （[ 36.36±24.81）%]，“ recommended opinions” （[ 53.25±19.20）%]，“ review and quality assurance” [0 （0， 25.00%）]， “funding and conflict of interest statement and management” [12.50%（0，25.00%）]， and other aspects [8.33%（0， 50.00%）]. In addition， there was no statistically significant difference in the AGREE Ⅱ and RIGHT scores between the guidelines and consensuses （P＞0.05）. CONCLUSIONS The overall quality of the guidelines and consensuses included in this study is not high， with a recommended level of B or C. It is recommended that clinical decision-making prioritize referring to the relatively high-quality guideline/consensus among them. The quality of evidence in the existing traditional Chinese medicine guidelines for children with ITP needs to be improved， and there is no integrated guideline/consensus for traditional Chinese and Western medicine. It is recommended to revise or write relevant guideline/consensus according to the requirements of AGREE Ⅱ and RIGHT in various fields to guide clinical practice.

Primary ciliary dyskinesia (PCD) is a genetically heterogeneous disease characterized by structural or functional abnormalities of motile cilia. It often presents clinically with recurrent respiratory infections, situs inversus, hydrocephalus, and infertility. Currently, there is no clinical treatment to directly restore ciliary motility in PCD patients.In recent years, researchers have explored gene therapy methods such as gene replacement, gene editing, and RNA replacement in vitro and in mouse models, offering potential new strategies for PCD treatment. This paper comprehensively reviews the current status of PCD gene therapy research, evaluates the potential of different gene therapies, and provides an outlook on the future treatment directions for this disease.

ObjectiveTo compare the clinical features of patients with hepatitis B virus （HBV）-related early-onset liver cancer and those with late-onset liver cancer， to assess the severity of the disease， and to provide a theoretical basis for the early diagnosis and treatment of liver cancer. MethodsA retrospective analysis was performed for 695 patients who were diagnosed with HBV-related liver cancer for the first time in Guangzhou Eighth People’s Hospital， Guangzhou Medical University， from January 2019 to August 2023， among whom 93 had early-onset liver cancer （defined as an age of50 years for female patients and40 years for male patients） and 602 had late-onset liver cancer （defined as an age of ≥50 years for female patients and ≥40 years for male patients）. Related clinical data were collected， including demographic data， clinical symptoms at initial diagnosis， comorbidities， smoking history， drinking history， family history， routine blood test results， biochemical parameters of liver function， serum alpha-fetoprotein（AFP）， virological indicators， coagulation function， and imaging findings. The pan-inflammatory indices neutrophil-to-lymphocyte ratio （NLR）， platelet-to-lymphocyte ratio （PLR）， and lymphocyte-to-monocyte ratio （LMR） were calculated， as well as FIB-4 index， aspartate aminotransferase-to-platelet ratio index （APRI）， S index， Model for End-Stage Liver Disease （MELD） score， Child-Turcotte-Pugh （CTP） score， albumin-bilirubin （AIBL） grade， and Barcelona Clinic Liver Cancer （BCLC） stage. The independent-samples t test was used for comparison of normally distributed continuous data between two groups， and the Wilcoxon rank-sum test was used for comparison of non-normally distributed continuous data between two groups； the chi-square test or Fisher’s exact test were used for comparison of categorical data between two groups. ResultsThere were significant differences between the two groups in the proportion of male patients and the incidence rates of diabetes， hypertension， and fatty liver disease （χ²=6.357， 15.230， 11.467， and 14.204， all P0.05）， and compared with the late-onset liver cancer group， the early-onset liver cancer group had a significantly higher proportion of patients progressing to liver cancer without underlying cirrhosis （χ²=24.657， P0.001） and a significantly higher proportion of patients with advanced BCLC stage （χ²=6.172， P=0.046）. For the overall population， the most common clinical symptoms included abdominal distension， abdominal pain， poor appetite， weakness， a reduction in body weight， edema of both lower limbs， jaundice， yellow urine， and nausea， and 55 patients （7.9%） had no obvious symptoms at the time of diagnosis and were found to have liver cancer by routine reexamination， physical examination suggesting an increase in AFP， or radiological examination indicating hepatic space-occupying lesion； compared with the late-onset liver cancer group， the patients in the early-onset liver cancer group were more likely to have the symptoms of abdominal distension， abdominal pain， and jaundice （all P0.05）. Compared with the late-onset liver cancer group， the early-onset liver cancer group had a significantly larger tumor diameter （Z=2.845， P=0.034）， with higher prevalence rates of multiple tumors and intrahepatic， perihepatic， or distant metastasis （χ²=5.889 and 4.079， both P0.05）， and there were significant differences between the two groups in tumor location and size （χ²=3.948 and 11.317， both P0.05）. Compared with the late-onset liver cancer group， the early-onset liver cancer group had significantly lower FIB-4 index， proportion of patients with HBsAg ≤1 500 IU/mL， and levels of LMR and Cr （all P0.05）， as well as significantly higher positive rate of HBeAg and levels of log₁₀ HBV DNA， AFP， WBC， Hb， PLT， NLR， PLR， TBil， ALT， Alb， and TC （all P0.05）. ConclusionCompared with late-onset liver cancer， patients with early-onset liver cancer tend to develop liver cancer without liver cirrhosis and have multiple tumors， obvious clinical symptoms， and advanced BCLC stage， which indicates a poor prognosis.

Cancer stem cells (CSCs) are widely acknowledged as primary mediators to the initiation and progression of tumors. The association between microbial infection and cancer stemness has garnered considerable scholarly interest in recent years. Porphyromonas gingivalis (P. gingivalis) is increasingly considered to be closely related to the development of oral squamous cell carcinoma (OSCC). Nevertheless, the role of P. gingivalis in the stemness of OSCC cells remains uncertain. Herein, we showed that P. gingivalis was positively correlated with CSC markers expression in human OSCC specimens, promoted the stemness and tumorigenicity of OSCC cells, and enhanced tumor formation in nude mice. Mechanistically, P. gingivalis increased lipid synthesis in OSCC cells by upregulating the expression of stearoyl-CoA desaturase 1 (SCD1) expression, a key enzyme involved in lipid metabolism, which ultimately resulted in enhanced acquisition of stemness. Moreover, SCD1 suppression attenuated P. gingivalis-induced stemness of OSCC cells, including CSCs markers expression, sphere formation ability, chemoresistance, and tumor growth, in OSCC cells both in vitro and in vivo. Additionally, upregulation of SCD1 in P. gingivalis-infected OSCC cells was associated with the expression of KLF5, and that was modulated by P. gingivalis-activated NOD1 signaling. Taken together, these findings highlight the importance of SCD1-dependent lipid synthesis in P. gingivalis-induced stemness acquisition in OSCC cells, suggest that the NOD1/KLF5 axis may play a key role in regulating SCD1 expression and provide a molecular basis for targeting SCD1 as a new option for attenuating OSCC cells stemness.

Tuberous sclerosis complex(TSC)is a rare genetic disease that can lead to benign dysplasia in multiple organs such as the skin, brain, eyes, oral cavity, heart, lungs, kidneys, liver, and bones. Its main symptoms include epilepsy, intellectual disabilities, skin depigmentation, and facial angiofibromas, whilst incidence is approximately 1 in 10 000 to 1 in 6000 newborns. This case presents a middle-aged woman who initially manifested with epilepsy and nodular depigmentation. Later, she developed a lower abdominal mass, elevated creatinine, and severe anemia. Based on clinical features and whole exome sequencing, the primary diagnosis was confirmed as TSC. Laboratory and imaging examinations revealed that the lower abdominal mass originated from the uterus. CT-guided biopsy pathology and surgical pathology suggested a combination of leiomyoma and abscess. With the involvement of multiple organs and various complications beyond the main diagnosis, the diagnostic and therapeutic process for this patient highlights the importance of rigorous clinical thinking and multidisciplinary collaboration in the diagnosis and treatment of rare and challenging diseases.

This study investigated the primary pathogenesis and syndrome evolution of different heart failure with preserved ejection fraction(HFpEF)stages based on the classical and clinical experience of traditional Chinese medicine(TCM),combined with the clinical characteristics of pre-heart failure,symptomatic heart failure,and advanced heart failure.This study summarizes and refines the three core syndrome factors:water,deficiency and blood stasis.Water-fluid retention was observed throughout these three stages,from the beginning to the end.With the advancement of the disease,the heart yang changes from stagnation to deficiency,water-fluid retention gradually increases,blood stasis becomes increasingly prominent,and the disease location develops dynamically from the upper to the middle and lower jiao.This study proposes three methods of treating HFpEF.The main pathogenesis of pre-heart failure is lung qi dysfunction-induced water retention,which can be treated by dispersing lung qi and transforming water retention using Fuling Xingren Gancao Decoction.The primary pathogenesis of symptomatic heart failure is yang and qi deficiency-induced water retention,which can be treated with tonifying yang,supplementing qi,and transforming water retention using Shengxian Decoction combined with Linggui Zhugan Decoction.The primary pathogenesis of advanced heart failure is yang deficiency with blood stasis and water retention affecting the heart,which can be treated with tonifying yang,circulating blood,and expelling water retention using Zhenwu Tingli Decoction.Chinese medicine can be flexibly added or subtracted according to the patients'concurrent patterns.However,the daily care of patients should be considered.This study explores the staging treatment of HFpEF from water,deficiency and blood stasis to provide a TCM clinical reference for treating HFpEF.

Objective To provide pharmaceutical care for patients with hepatitis B cirrhosis by using the medication therapy management(MTM)model combined with Pharmaceutical Care Network Europe(PCNE),and to analyze the effectiveness of pharmaceutical care from clinical efficacy,safety,humanistic effect and drug-related problems(DRPs).Methods Patients with hepatitis B cirrhosis were randomly divided into the pharmaceutical care group and the control group who received only conventional treatment.Clinical pharmacists used MTM combined with PCNE to provide pharmaceutical care in the pharmaceutical care group.Economic effects,clinical indicators,safety,medication compliance and quality of life were compared between the two groups during the treatment and follow-up period.DRPs were analyzed in the pharmaceutical care group.Results The cost-utility ratio and clinical indicators in the pharmaceutical care group were better than those in the control group,and the adverse drug reactions of the former were statistically significant compared with the latter at the three months follow-up,and medication compliance and quality of life were statistically significant after intervention and during follow-up(P＜0.05).There were 52 DRPs in the pharmaceutical care group,mainly in the category of poor treatment outcome.The main reasons were poor drug selection and excessive usage and dosage.There were 46 DRPs accepted by intervention,and 45 DRPs were completely and partially solved.Conclusion The pharmaceutical care model of MTM combined with PCNE classification system for patients with hepatitis B cirrhosis played a positive role in the treatment and follow-up period.

Objective:To analyze the effects of rehabilitation nursing under the guidance of electrical impedance tomography (EIT) on mechanical ventilation time and complications in ICU patients with respiratory failure so as to promote the systematic improvement of pulmonary rehabilitation nursing exercise measures.Methods:In the randomized controlled trial, 80 patients with respiratory failure admitted to ICU of Quzhou People′s Hospital were enrolled between July 2021 and July 2022 by convenience sampling method. According to different admission time, patients were divided into control group (40 cases, July-December 2021, routine rehabilitation nursing) and observation group (40 cases, February-July 2022, EIT-guided rehabilitation nursing). The lung function indexes, stay time in ICU, mechanical ventilation time, blood gas indexes and incidence of complications were compared between the two groups.Results:There were 22 males and 18 females in the control group, with an age of (53.54 ± 5.17) years; there were 21 males and 19 females in the observation group, with an age of (52.82 ± 5.21) years.After intervention, forced expiratory volume in the first second (2.82 ± 0.67) L, forced expiratory volume/forced vital capacity in the first second (78.87 ± 4.82) % and forced expiratory volume in the first second as a percentage of the predicted value (74.24 ± 9.65) % in observation group were higher than those in control group [(2.10 ± 0.66) L, (65.59 ± 3.67) %, (60.87 ± 9.66) %], and the differences were statistically significant ( t=4.84, 13.86, 6.19, all P<0.05). The stay time in ICU (10.37 ± 1.34)h and mechanical ventilation time (9.82 ± 1.24) h in observation group were shorter than those in control group (12.19 ± 1.22) h, (11.54 ± 1.37) h, and the differences were statistically significant ( t=6.35, 5.89, both P<0.05). After intervention, arterial oxygen partial pressure (90.76 ± 12.46) mmHg (1mmHg=0.133kPa) and oxygenation index (377.36 ± 54.38) in observation group were higher than those in control group (72.65 ± 11.65), (329.15 ± 42.26) mmHg, and the differences were statistically significant ( t=6.72, 4.43, both P<0.05), while arterial carbon dioxide partial pressure (45.32 ± 4.87) mmHg was lower than that in the control group (52.73 ± 4.27) mmHg, the differences was statistically significant ( t=7.24, P<0.05). The incidence of complications 7.50% (3/40) in observation group was lower than that in control group 25.00% (10/40), the differences was statistically significant ( χ2=4.50, P<0.05). Conclusions:EIT-guided rehabilitation nursing is beneficial to improve blood gas indexes and lung ventilation function, effectively shorten tracheal intubation time and stay time in ICU, and reduce the incidence of related complications in ICU patients with respiratory failure.

Thrombocytopenia is one of the common complications of cirrhotic patients, which can induce an increasing bleeding risk and closely correlate with bleeding following invasive procedures. Consequently, how to respond to thrombocytopenia is crucial for improving the prognosis of patients with cirrhosis. This article reviews the main mechanisms of cirrhosis concurrent with thrombocytopenia, as well as the corresponding clinical management strategies.

Objective To explore the mechanism of ginsenoside Rg1 in alleviating heat stress-induced testicular injury in mice.Methods A total of 20 C57BL/6 male mice(6～8 weeks old)were randomly divided into 4 groups(n=5).The mice from the control group and heat stress(HS)group were intraperitoneally injected with 10 mL/(kg·d)0.9％normal saline for 14 d,while those in the HS+Rg1 group and the Rg1 group were given an intraperitoneal injection of 20 mg/(kg·d)for 14 d,and then on the 7th day after administration,the mice in the HS group and the HS+Rg1 group had the lower abdomen put into a 43 ℃ water bath for 30 min as a single heat stress after being anesthetized with 4％chloral hydrate.Mouse spermatocytes GC-2spd(ts)were divided into control group(routine culture for 48 h),HS group(placed in a 43 ℃ water bath for 30 min after 36 h of conventional culture,and cultured till the end of 48 h),HS+Rg1 group(50 μmol/L Rg1 treatment followed by heat stress injury),and Rg1 group(no heat stress injury).In 1 d after modeling,the eyeball blood samples were collected to detect serum testosterone with ELISA,and the testicles were extracted to observe the morphology and weighed to calculate the testicular index.HE staining was used to observe the histopathology of testis,and corresponding reagents and kits was employed to detect the content of malondialdehyde(MDA)and activities of catalase(CAT)and superoxide dismutase(SOD)in testis tissue.After the epididymal sperm were collected,the sperm concentration and motility were analyzed by computer-assisted sperm analysis(CASA)system.In in vitro experiments,cell apoptosis was detected with TUNEL staining,the protein levels of Nrf2,Keap1,HO-1,Bax,Bcl-2 and Caspase3 were detected with Western blotting,and the mRNA levels of GCLC,GCLM and NQO1 were detected by RT-qPCR.Results Rg1 prevented the decreases in testicular weight and testicular index caused by heat stress,reduced the damage of testicular tissue structure,prevented the decrease of sperm concentration and vitality,antagonized the decreasd number of Leydig cells and serum testosterone level,reduced the accumulation of MDA in testicular tissue,and enhanced the activities of CAT and SOD.Rg1 treatment alleviated the apoptosis of GC-2spd(ts)cells,down-regulated the expression of Bax,Caspase3 and Keap1 proteins,enhanced the expression of Bcl-2,Nrf2 and HO-1 proteins,and increased the transcriptional levels of Nrf2 target genes GCLC,GCLM and NQO1.Conclusion Rg1 has no significant effect on the structure and function of mouse testes,but it can effectively improve the ability of mouse testes to resist heat stress injury,which may be related to the activation of Nrf2 signaling pathway,the improvement of antioxidant enzyme activity,and the reduction of apoptosis of spermatogenic cells.
