Objective To investigate the current status,evolving hotspots,and emerging trends in the field of human re-source allocation research in public hospitals,both domestically and internationally,to provide a reference for future research di-rections in China.Methods CiteSpace was used to conduct a visual analysis of the research literature on human resource alloca-tion in public hospitals based on China National Knowledge Infrastructure(CNKI)and the Web of Science(WOS).The analysis encompassed co-authorship,institutional collaboration,keyword co-occurrence and clustering,and burst detection.Results A total of 1 417 Chinese articles and 981 international articles were included.Domestic research in this field focused more on healthcare reform and management,resource allocation,hierarchical diagnosis,and treatment,and informatization and efficiency improvement.On the contrary,international research primarily centered on the employee satisfaction,healthcare system quality,work environment and medical staff.Future trends in domestic research included cost reduction,efficiency enhancement,and a greater emphasis on public welfare in public hospitals,while international research was beginning to explore the influence of polit-ical concepts in this field.Conclusion Compared to international research,domestic research needs to further improve its theo-retical and localized understanding,broaden its research scope,explore the interdisciplinary collaboration opportunities,and delve into research directions such as the application of artificial intelligence and automation technology in healthcare services,management of a diverse workforce,and innovative management techniques and applications.

Objective This study aimed to comprehensively analyze and compare the clinicopathological features and prognosis of Chinese patients with human epidermal growth factor receptor 2(HER2)-low early breast cancer(BC)and HER2-IHC0 BC. Methods Patients diagnosed with HER2-negative BC(N=999)at our institution between January 2011 and December 2015 formed our study population.Clinicopathological characteristics,association between estrogen receptor(ER)expression and HER2-low,and evolution of HER2 immunohistochemical(IHC)score were assessed.Kaplan-Meier method and log-rank test were used to compare the long-term survival outcomes(5-year follow-up)between the HER2-IHC0 and HER2-low groups. Results HER2-low BC group tended to demonstrate high expression of ER and more progesterone receptor(PgR)positivity than HER2-IHC0 BC group(P<0.001).The rate of HER2-low status increased with increasing ER expression levels(Mantel-Haenszel χ2 test,P<0.001,Pearson's R=0.159,P<0.001).Survival analysis revealed a significantly longer overall survival(OS)in HER2-low BC group than in HER2-IHC0 group(P=0.007)in the whole cohort and the hormone receptor(HR)-negative group.There were no significant differences between the two groups in terms of disease-free survival(DFS).The discordance rate of HER2 IHC scores between primary and metastatic sites was 36.84%. Conclusion HER2-low BC may not be regarded as a unique BC group in this population-based study due to similar clinicopathological features and prognostic roles.

With the increasing proportion of human papilloma virus(HPV)infection in the pathogenic factors of oro-pharyngeal cancer,a series of changes have occurred in the surgical treatment.While the treatment mode has been im-proved,there are still many problems,including the inconsistency between diagnosis and treatment modes,the lack of popularization of reconstruction technology,the imperfect post-treatment rehabilitation system,and the lack of effective preventive measures.Especially in terms of treatment mode for early oropharyngeal cancer,there is no unified conclu-sion whether it is surgery alone or radiotherapy alone,and whether robotic minimally invasive surgery has better func-tional protection than radiotherapy.For advanced oropharyngeal cancer,there is greater controversy over the treatment mode.It is still unclear whether to adopt a non-surgical treatment mode of synchronous chemoradiotherapy or induction chemotherapy combined with synchronous chemoradiotherapy,or a treatment mode of surgery combined with postopera-tive chemoradiotherapy.In order to standardize the surgical treatment of oropharyngeal cancer in China and clarify the indications for surgical treatment of oropharyngeal cancer,this expert consensus,based on the characteristics and treat-ment status of oropharyngeal cancer in China and combined with the international latest theories and practices,forms consensus opinions in multiple aspects of preoperative evaluation,surgical indication determination,primary tumor re-section,neck lymph node dissection,postoperative defect repair,postoperative complication management prognosis and follow-up of oropharyngeal cancer patients.The key points include:① Before the treatment of oropharyngeal cancer,the expression of P16 protein should be detected to clarify HPV status;② Perform enhanced magnetic resonance imaging of the maxillofacial region before surgery to evaluate the invasion of oropharyngeal cancer and guide precise surgical resec-tion of oropharyngeal cancer.Evaluating mouth opening and airway status is crucial for surgical approach decisions and postoperative risk prediction;③ For oropharyngeal cancer patients who have to undergo major surgery and cannot eat for one to two months,it is recommended to undergo percutaneous endoscopic gastrostomy before surgery to effectively improve their nutritional intake during treatment;④ Early-stage oropharyngeal cancer patients may opt for either sur-gery alone or radiation therapy alone.For intermediate and advanced stages,HPV-related oropharyngeal cancer general-ly prioritizes radiation therapy,with concurrent chemotherapy considered based on tumor staging.Surgical treatment is recommended as the first choice for HPV unrelated oropharyngeal squamous cell carcinoma(including primary and re-current)and recurrent HPV related oropharyngeal squamous cell carcinoma after radiotherapy and chemotherapy;⑤ For primary exogenous T1-2 oropharyngeal cancer,direct surgery through the oral approach or da Vinci robotic sur-gery is preferred.For T3-4 patients with advanced oropharyngeal cancer,it is recommended to use temporary mandibu-lectomy approach and lateral pharyngotomy approach for surgery as appropriate;⑥ For cT1-2N0 oropharyngeal cancer patients with tumor invasion depth＞3 mm and cT3-4N0 HPV unrelated oropharyngeal cancer patients,selective neck dissection of levels ⅠB to Ⅳ is recommended.For cN+HPV unrelated oropharyngeal cancer patients,therapeutic neck dissection in regions Ⅰ-Ⅴ is advised;⑦ If PET-CT scan at 12 or more weeks after completion of radiation shows intense FDG uptake in any node,or imaging suggests continuous enlargement of lymph nodes,the patient should undergo neck dissection;⑧ For patients with suspected extracapsular invasion preoperatively,lymph node dissection should include removal of surrounding muscle and adipose connective tissue;⑨ The reconstruction of oropharyngeal cancer defects should follow the principle of reconstruction steps,with priority given to adjacent flaps,followed by distal pedicled flaps,and finally free flaps.The anterolateral thigh flap with abundant tissue can be used as the preferred flap for large-scale postoperative defects.

Objective To explore the therapeutic mechanism of Liuwei Buqi(LWBQ)Formula for chronic obstructive pulmonary disease(COPD)in rat models.Methods SD rat models of COPD established by cigarette smoking combined with intratracheal lipopolysaccharide(LPS)instillation and hormone injection were treated with LWBQ Formula by gavage with or without intraperitoneal injection of MCC950 for 3 weeks,starting at the 5th week of modeling.After the treatments,the rats were examined for lung pathologies,lung function,total cell count and white blood cell count in bronchoalveolar lavage fluid(BALF),and serum levels of IL-6,TNF-α,IL-18 and NO.The mRNA expressions of NLRP3,ASC,caspase-1,GSDMD-N,IL-1β,and IL-18 in the lung tissue were detected with qRT-PCR.Results Compared with the normal control rats,the COPD rat models had severe lung pathologies and showed significantly decreased lung function,increased total cell and leukocyte subset counts in BALF,and increased serum levels of IL-6,TNF-α,IL-18 and NO and mRNA expressions of pyroptosis-related proteins in the lung tissue.Treatment of the rat models with LWBQ Formula significantly improved lung pathology and lung function,reduced total cell and leukocyte counts in BALF,and decreased serum levels of the inflammatory factors and expressions of pyroptosis-related proteins in the lung tissue.The combined treatment with MCC950 further improved lung pathology and function in spite of a significant difference,but BALF cell counts,serum inflammatory factor levels and pulmonary expressions of pyroptosis-related proteins were all significantly reduced following the treatment.Conclusion LWBQ Formula can delay the progression of COPD in rats possibly by inhibiting lung tissue pyroptosis via regulating the NLRP3/caspase-1/GSDMD pathway to reduce inflammatory response and lung damage.

Objective To explore the distribution and drug resistance of pathogenic bacteria of infectious diseases in a grade-A tertiary hospital from 2020 to 2022.Methods The clinical data of totally 1 928 children with infectious diseases admitted to a grade-A tertiary hospital from 2020 to 2022 were retrospectively ana-lyzed.Bacterial identification and drug susceptibility tests were performed on sputum,blood,feces,secretions,urine and cerebrospinal fluid samples of all children after admission,and then the distribution of pathogenic bacteria and drug resistance were statistically analyzed.Results In this study,a total of 1 928 strains of non-repeating pathogens were isolated from a grade-A tertiary hospital from 2020 to 2022,and the pathogens were mainly isolated from the sputum(67.17％),followed by blood(12.03％),feces(11.00％),secretions(6.48％),urine(2.70％)and cerebrospinal fluid(0.62％).Among the 1 928 strains,1 202 gram-negative strains(62.34％)were mainly Haemophilus influenzae and Moraxella catarrhal,accounting for 24.17％and 15.82％respectively.There were 726 strains of gram-positive bacteria(37.66％),mainly streptococcus pneu-moniae and Staphylococcus aureus,accouting for 21.59％and 12.29％respectively.In addition,the pathogens in 2020-2022 accounted for 32.57％(628/1 928),38.43％(741/1 928)and 28.99％(559/1 928),respective-ly.The resistance rates of Haemophilus influenzae to ampicillin/sulbactam,cotrimoxazole,sulfamethoxazole/trimethoprim were more than 65.00％.The resistance rates of Moraxella catarrhal to cotrimoxazole,ampicil-lin/sulbactam were more than 40.00％.The resistance rates of Streptococcus pneumoniae to clindamycin,pen-icillin,sulfamethoxazole/trimethoprim and erythromycin were more than 87.00％.The resistance rates of Staphylococcus aureus to clindamycin,erythromycin and penicillin were more than 47.00％,and the resistance rate to penicillin was 88.61％.Conclusion From 2020 to 2022,the pathogens of infectious diseases in a grade-A tertiary hospital are mainly gram-negative bacteria,and there are different degrees of resistance to common-ly used clinical antibiotics.Therefore,in clinical practice,nosocomial infection prevention and control measures should be strictly implemented,antibiotics should be used carefully,and antibiotics could be selected reasona-bly according to the distribution characteristics of children's infection and drug sensitivity test results,which is of great significance for the prevention of hospital infectious diseases.

Objective To explore the effect of a multiple heat-preservation approach during the peri-operative period of hip arthroscopy on core body temperature,anesthesia recovery time and postopera-tive shivering.Methods Eighty patients who underwent arthroscopic acetabular labral repair between Jan-uary 2020 and June 2021 were selected and randomly divided into a control group and an observation group,each of 40.During the perioperative period,both groups received routine nursing,while the ob-servation group was additionally provided with a series of heat-preservation measures including raising the room temperature,liquid heating and warm blanket insulation.The core body temperature was mon-itored by an axillary probe.Moreover,the perioperative core body temperature,anesthesia recovery time,and incidence of postoperative shivering were compared between the two groups.Results There was no significant differences were found between the two groups in the preoperative core body temper-ature(P>0.05).However,the core body temperature of the observation group was significantly higher than the control group intraoperatively(36.2℃±0.2℃vs 35.9℃±0.2℃,P<0.001)and postoperatively(36.6℃±0.2℃vs 36.4℃±0.2℃,P<0.001),while the incidence of intraoperative hypothermia(<36.0℃)of the observation group was significantly lower than the latter(7.5%vs 70.0%,P<0.001).Meanwhile,the anesthesia recovery time[27.0(24.0,30.0)min vs 30.0(28.0,33.0)min,M(P25,P75),P<0.001]and incidence of postoperative shivering(7.5%vs 25.0%,P=0.034)in the observation group were significantly lower than the control group.Conclusion Adopting a multiple heat-preservation approach during the perioperative period of hip arthroscopy can help maintain the core body tempera-ture,shorten the anesthesia recovery time,and reduce the incidence of postoperative shivering.

AIM To investigate the ameliorative effects of Schisandrol A(Sol A)in Suhuang antitussive capsule on post-infectious cough(PIC).METHODS The in vivo mouse PIC model was established by intratracheal instillation of lipopolysaccharide(LPS)combined with cigarette smoke exposure.The mice were randomly divided into the control group,the model group,the Suhuang antitussive capsule group(14 g/kg),the montelukast sodium positive control group(3 mg/kg),and low and high dose Sol A groups(10,30 mg/kg).The in vitro PIC model was established by stimulating human bronchial epithelial cells(BEAS-2B)with LPS.The cells were divided into the control group,the model group,the Suhuang antitussive capsule group(10 μg/mL)and low and high dose Sol A groups(3,10 μmol/L).HE and Masson staining were used to detect the pathological changes of the lung and bronchial tissues.ELISA was used to detect the levels of IL-1β,IL-6,TNF-α,ROS,MDA,SOD and GSH in the lung tissues.RT-qPCR was used to detect the IL-1β,IL-6 and TNF-α mRNA expressions in BEAS-2B cells.And Western blot was applied to detect the protein expressions of p-PI3K,p-Akt,NOX4,SIRT1,p-ERK,Fibronectin,E-cadherin,Vimentin and α-SMA in mouse lung tissue and BEAS-2B cells.RESULTS Compared with the model group,the groups intervened with Sol A or Suhuang antitussive capsule displayed prolonged cough latency(P＜0.01);reduced cough frequency(P＜0.01);relieved pulmonary inflammatory cell infiltration and collagen deposition in PIC mice;decreased pulmonary levels of IL-1β,IL-6,TNF-α,ROS,MDA and protein expressions of Fibronectin,Vimentin,α-SMA,p-ERK,p-PI3K,p-Akt,and NOX4(P＜0.05,P＜0.01);increased pulmonary levels of SOD and GSH and protein expressions of E-cadherin and SIRT1(P＜0.05,P＜0.01);decreased ROS level,IL-1β,IL-6,TNF-α mRNA expressions and p-ERK,p-PI3K,p-Akt,NOX4 protein expressions in vitro(P＜0.05,P＜0.01);and increased SIRT1 protein expression in vitro as well(P＜0.01).CONCLUSION Being the main antitussive component of Suhuang antitussive capsule upon the PIC model,Sol A inhibits the inflammation via SIRT1/ERK signaling pathway and relieve the oxidative stress via PI3K/Akt/NOX4 signaling pathway.

Objective: To investigate the demographic characteristics and clinical influencing factors which associates with the occurrence probability of persistent or intermittent hypoviremia (LLV) in patients with chronic hepatitis B (CHB) treated with nucleos(t)ide analogues (NAs). Methods: A single-center retrospective analysis was performed on patients with CHB who received outpatient NAs therapy for≥48 ± 2 weeks. According to the serum hepatitis B virus (HBV) DNA load at 48±2 weeks treatment, the study groups were divided into LLV (HBV DNA < 20 IU/ml and < 2 000 IU/ml) and MVR group (sustained virological response, HBV DNA < 20 IU/ml). Demographic characteristics and clinical data at the start of NAs treatment (considered as baseline) were retrospectively collected for both patient groups. The differences in the reduction of HBV DNA load during treatment was compared between the two groups. Correlation and multivariate analysis were further conducted to analyze the associated factors influencing the LLV occurrence. Statistical analysis was performed using the independent samples t-test, c2 test, Spearman analysis, multivariate logistic regression analysis, or area under the receiver operating characteristic curve. Results: A total of 509 cases were enrolled, with 189 and 320 in the LLV and MVR groups, respectively. Compared to patients with MVR group at baseline: (1) the demographics characteristics of patients showed that LLV group was younger in age (39.1 years, P = 0.027), had a stronger family history (60.3%, P = 0.001), 61.9% received ETV treatment, and higher proportion of compensated cirrhosis (20.6%, P = 0.025) at baseline; (2) the serum virological characteristics of patients showed that LLV group had higher HBV DNA load, qHBsAg level, qHBeAg level, HBeAg positive rate, and the proportion of genotype C HBV infection but decreased HBV DNA during treatment (P < 0.001) at baseline; (3) the biochemical characteristics of patients showed that LLV group had lower serum ALT levels (P = 0.007) at baseline; (4) the noninvasive fibrosis markers of patients showed that LLV group were characterized by high aspartate aminotransferase platelet ratio index (APRI) (P = 0.02) and FIB-4 (P = 0.027) at baseline. HBV DNA, qHBsAg and qHBeAg were positively correlated with LLV occurrence (r = 0.559, 0.344, 0.435, respectively), while age and HBV DNA reduction were negatively correlated (r = -0.098, -0.876, respectively). Logistic regression analysis showed that ETV treatment history, high HBV DNA load at baseline, high qHBsAg level, high qHBeAg level, HBeAg positive, low ALT and HBV DNA level were independent risk factors for patients with CHB who developed LLV with NAs treatment. Multivariate prediction model had a good predictive value for LLV occurrence [AUC 0.922 (95%CI: 0.897 ~ 0.946)]. Conclusion: In this study, 37.1% of CHB patients treated with first-line NAs has LLV. The formation of LLV is influenced by various factors. HBeAg positivity, genotype C HBV infection, high baseline HBV DNA load, high qHBsAg level, high qHBeAg level, high APRI or FIB-4 value, low baseline ALT level, reduced HBV DNA during treatment, concomitant family history, metabolic liver disease history, and age < 40 years old are potential risk factors for developing LLV in patients with CHB during the therapeutic process.

ObjectiveTo investigate the effect of Mashao Pingchuan decoction （MSPC） on lipopolysaccharides （LPS）-induced autophagy in human bronchial airway epithelial cells （16HBE） via the phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt）/mammalian target of rapamycin （mTOR） signaling pathway. Method16HBE cells were selected for the study， and cell counting kit-8 （CCK-8） was used to detect the activity of of LPS-induced 16HBE cells and the effect of MSPC-containing serum on the cells. Suitable LPS-induced 16HBE cells were screened by the CCK-8 method， and the content of tumor necrosis factor-α （TNF-α） was measured to identify the established model. And MSPC-containing serum was prepared. The cells were divided into normal group， LPS group， LPS+MSPC group， LY294002+LPS group and LY294002+LPS+MSPC group. Transmission electron microscopy was performed to observe the changes in autophagic vesicles and ultrastructure of the cells. Western blot was performed to detect the protein expressions of PI3K， phosphorylated PI3K （p-PI3K）， Akt， phosphorylated Akt （p-Akt）， mTOR， phosphorylated mTOR （p-mTOR） and microtubule-associated protein 1 light chain 3B （LC3B）， and enzyme-linked immunosorbent assay （ELISA） was used to detect the expressions of inflammatory factors interleukin-5 （IL-5）， IL-6， TNF-α and IL-10 in the five groups. ResultLPS inhibited the 16HBE cells in a dose-dependent manner. Compared with the normal group， the LPS group （150 mg·L^-1 of LPS） increased the expression of pro-inflammatory factor TNF-α after 24 h of treatment （P<0.05） and facilitated the autophagosome formation， and MSPC-containing serum exerted a concentration-dependent promotion effect on the 16HBE cells， inhibited the autophagy to a certain degree and enhanced the cell status. Western blot revealed that the protein expressions of p-PI3K， p-Akt and p-mTOR in the model group were lower （P<0.05） and the protein expression of LC3B was higher （P<0.01） than those in the normal group. Compared with the conditions in the LPS group， the protein expressions of p-PI3K， p-Akt and p-mTOR in the LPS+MSPC group were elevated （P<0.05） and that of LC3B was reduced （P<0.05）. Compared with the LPS+LY294002 group， the LY294002+LPS+MSCP group had up-regulated protein expressions of p-PI3K， p-Akt and p-mTOR （P<0.05） and down-regulated protein expression of LC3B （P<0.05）. ELISA showed that the LPS group had higher levels of IL-5， IL-6， TNF-α and IL-10 than the normal group， while the levels of TNF-α， IL-6 and IL-8 were decreased （P<0.01） and the level of IL-10 was increased （P<0.01） after treatment with MSCP. ConclusionMSCP may lower the LPS-induced autophagy in 16HBE cells and improve the inflammatory response through activating the PI3K/Akt/mTOR signaling pathway.
