OBJECTIVE To investigate the basic situation of developing pharmacy outpatient departments in Chinese tertiary medical institutions and analyze the influencing factors. METHODS The research targeted the pharmacy outpatient department managers of hospitals and conducted a survey through Sojump in March 2023. Various independent variables were selected from the hospital’s own characteristics， the management of the pharmacy outpatient departments， and the construction of the pharmacist team for Logistic and linear regression analysis， with the aim of separately analyzing the factors influencing the establishment of pharmacy outpatient departments and the factors affecting the total number of patients served by these departments throughout the year 2022. RESULTS & CONCLUSIONS A total of 1 304 medical institutions of different levels nationwide participated in this survey， with 714 tertiary hospitals. Among the tertiary hospitals， 377 （52.80%） had established pharmacy outpatient departments， including 321 grade-A tertiary hospitals， 48 grade-B tertiary hospitals and 8 other tertiary hospitals. The 377 tertiary hospitals collectively operated 1 739 pharmacy outpatient departments， covering 19 specialized fields， with the highest proportion found in the cardiovascular field （including anticoagulation） at 16.45%. Tertiary hospitals in North China， Central China， East China and South China regions had more pharmacy outpatient departments. The establishment of pharmacy outpatient departments was found to be influenced by tertiary grade-B status （P＝0.010） and the annual outpatient volume of the hospital （P＝0.008）， although the impact was relatively small. The factors influencing the number of patients served by pharmacy outpatient departments were the annual outpatient volume of the hospital （P＝0.042） and the number of pharmacists engaged in clinical pharmacy work （P＝0.004）. The proportion of tertiary hospitals in China that have established pharmacy outpatient departments is insufficient. It is necessary to further accelerate the construction of pharmacy outpatient departments and appropriately expand the talent pool of hospital pharmacy teams based on the needs of pharmacy outpatient departments and patients， in order to meet the requirements of medical practice and patient care.

High flow nasal cannula（HFNC）is a novel oxygen therapy developed in recent years，and has been successfully used in pediatric diseases such as bronchiolitis and pneumonia.Although there has been a lack of clinical application guidelines in pediatrics，it has been increasingly applied to the treatment of exacerbations of bronchial asthma.This review focused on efficacy，application timing，complications and parameters adjustment of HFNC in children with asthma exacerbation，so as to further guide the clinical use.

Objective:To observe the effects of modified Taohong Siwu Decoction on peripheral circulation status of affected limbs and serum thromboxane B 2 (TXB 2) and prostacyclin (PGI 2) levels in patients with traumatic limb fractures after open reduction and internal fixation. Methods:Randomized controlled trial study was conducted. 70 patients with traumatic limb fractures who underwent open reduction and internal fixation in the hospital from February 2020 to February 2023 were set as observation subjects and divided into control group (34 cases) and observation group (36 cases) according to the order of hospitalization. The control group was given conventional method for treatment, and the observation group was given modified Taohong Siwu Decoction adjuvant therapy on the basis of the control group. The treatment for both groups lasted for 2 weeks. TCM symptoms scores were evaluated before and after treatment. Ankle brachial index (ABI) was detected using a Doppler blood flow detector. Color Doppler ultrasound was used to detect the inner diameter, blood flow, and deep veins of the affected limb; serum levels of TXB 2 and PGI 2 were detected by ELISA. Results:After treatment, the total effective rate of clinical efficacy was 91.67% (33/36) in observation group and 73.53% (25/34) in control group, with statistical significance ( P<0.05). After treatment, the observation group had lower scores for qi and blood stasis (2.13 ± 0.43 vs. 3.61 ± 0.96, t=5.85), tendon and bone injury (1.62 ± 0.41 vs. 2.74 ± 0.58, t=9.37), swelling and ecchymosis (1.15 ± 0.31 vs. 2.28 ± 0.52, t=1.12), and liver and kidney deficiency (1.52 ± 0.24 vs. 2.15 ± 0.36, t=8.66) compared to the control group ( P<0.001); after treatment, the ABI (0.83 ± 0.03 vs. 0.74 ± 0.02, t=14.68), vascular diameter [(0.48 ± 0.13) mm vs. (0.42 ± 0.11) mm, t=2.08], and blood flow velocity [(60.24 ± 15.46) cm/s vs. (52.15 ± 12.11) cm/s, t=2.41] in the observation group were higher than those in the control group ( P<0.01 or P<0.05). After treatment, the serum TXB 2 levels [(140.76 ± 16.64) ng/L vs. (168.39 ± 25.28) ng/L, t=5.37] and TXB 2/PGI 2 (6.67 ± 1.24 vs. 9.33 ± 1.69, t=7.54) in the observation group were lower than those in the control group ( P<0.01); the level of PGI 2 [(21.27 ± 2.24) ng/L vs. (18.71 ± 1.79) ng/L, t=5.26] was higher in the control group ( P<0.01). The incidence of deep vein thrombosis after treatment in the observation group was 19.44% (7/36), while in the control group it was 44.12% (15/34), with statistical significance ( χ 2=4.94, P=0.026). Conclusion:Modified Taohong Siwu Decoction adjuvant therapy can enhance the clinical efficacy of patients with traumatic limb fractures after open reduction and internal fixation, relieve the TCM symptoms, improve the peripheral circulation status of affected limbs, reduce the postoperative hypercoagulability and prevent the deep venous thrombosis formation.

Objective This study established a model of invasive Aspergillus niger lung disease in immunosuppressed rats to provide theoretical support for the pharmacodynamic evaluation of anti-invasive pulmonary aspergillosis drugs and mechanism studies.Methods Sixty SD rats were randomly divided into a normal control group;cyclophosphamide control group,and cyclophosphamide+fungal infection low,medium,and high dose groups,with 12 animals in each group.General clinical observations were performed daily,and the serum levels of immunoglobulin(Ig)G and IgM and galactomannan(GM)were detected by ELISA on the 3rd and 7th days of modeling.Simultaneously,the ratio of CD4+and CD8+cells,content of white blood cells(WBCs)and neutrophils(Neu)in peripheral blood,the Aspergillus niger load in alveolar lavage,and morphological changes to rat lung tissue were observed.Results Rats in the cyclophosphamide control and cyclophosphamide+fungal infection groups showed reduced voluntary activity and erect hair after modeling,and rats in the cyclophosphamide+fungal infection group also had shortness of breath and audible wet rhonchi in the lungs.Compared with the normal control group,rats in the cyclophosphamide control group showed significant reductions in the levels of CD4+,WBC,Neu,IgG,and IgM in the blood,and their proportion of CD8+cells was significantly higher(P＜0.05,P＜0.01).Compared with the cyclophosphamide control group,rats in the cyclophosphamide+fungal infection medium-and high-dose groups had significantly reduced blood levels of IgG,IgM,and CD4+cells(P＜0.05,P＜0.01);while the cyclophosphamide+fungal infection low-,medium-,and high-dose groups had significantly reduced blood levels of WBC and Neu(P＜0.05,P＜0.01).Additionally,rats in the cyclophosphamide+fungal infection medium-and high-dose groups had significantly increased blood CD8+cells(P＜0.05,P＜0.01),Blood GM levels and the alveolar lavage Aspergillus niger load were significantly increased in rats in the cyclophosphamide+fungal infection low-,medium-,and high-dose groups compared with the cyclophosphamide control group(P＜0.05,P＜0.01).The lung tissues of the cyclophosphamide+fungal infection low-,medium-,and high-dose groups showed mycelial distribution and destruction of alveolar epithelium,increase of bronchial epithelial cup cells in the alveoli,and infiltration of inflammatory cells,and the degree of lesions was positively correlated with the modeling dose.Conclusions In this study,we used Aspergillus niger combined with cyclophosphamide immunosuppressant to construct a model of invasive Aspergillus niger lung disease.The duration of the disease was positively correlated with the concentration of bacterial fluid and modeling time,confirming that cellular immunity plays an important role in the pathogenesis of the disease.At the same time,Ig can also affect the development of invasive pulmonary aspergillosis,and it is speculated that the pathogenesis may be related to the level of Ig produced by humoral immunity.

Objective:To assess the characteristics and correlation of motor development in preterm infants of different gestational weeks by using the Test of Infant Motor Performance (TIMP) method, and to develop better individualized early interventions based on TIMP test results.Methods:A prospective study involving 43 full-term healthy infants and 77 preterm followed up in 3201 Hospital from June 2019 to July 2021 was conducted.Preterm infants were divided into the early preterm group (39 cases) and late preterm group (38 cases) according to their gestational age at birth.TIMP assessment was performed at the gestational age of 40 weeks and the corrected age of 16 weeks after birth.Similarly, the full-term healthy infants were assessed by TIMP at the postnatal age of 16 weeks.The differences between groups were investigated using ANOVA or Mann- Whitney rank sum test.Correlations were analyzed by the Pearson correlation method. Results:There were no significant difference in TIMP scores between early and late preterm infants at the gestational age of 40 weeks [(65.74±6.52) scores vs.(66.96±8.51) scores] and the corrected age of 16 weeks [(101±10) scores vs.(104±8) scores] (all P>0.05). TIMP scores in the full-term healthy group at the corrected age of 16 weeks [(108±10) scores] differed significantly from those of early and late preterm infants ( P<0.05). Compared with full-term infants, early and late preterm infants had lower TIMP scores in observation, supine position, and supine turning (all P<0.05), but a higher TIMP score in standing position ( P<0.05). For both early and late preterm infants, TIMP scores at the gestational age of 40 weeks were significantly positively correlated with those at the corrected age of 16 weeks ( r=0.565, 0.302, all P<0.01). Conclusions:There were significant differences in motor development between preterm infants of different gestational ages and term infants, which had guiding significance for early intervention.English version TIMP could play a positive role in promoting individualized follow-up and early intervention of preterm infants in China.

Objective: To analyze the incidence and the related risk factors of retropharyngeal lymph node metastasis in patients with hypopharyngeal squamous cell carcinoma, evaluate the accuracy of preoperative enhanced CT in judging retropharyngeal lymph node metastasis, and investigate the impact of retropharyngeal lymph node metastasis on the prognosis. Methods: Retrospective analyses were made on 398 patients with hypopharyngeal squamous cell carcinoma who underwent surgery as the primary therapy and accepted retropharyngeal lymph node exploration and clearance during surgery in Shandong Provincial ENT Hospital from January 2014 to December 2019. Multivariate logistic regression analysis was used to clarify the related risk factors of retropharyngeal lymph node metastasis. Multivariate Cox regression analysis was used to investigate the impact of retropharyngeal lymph node metastasis on prognosis. The retropharyngeal lymph nodes of 218 cases with available preoperative enhanced CT images were evaluated by two experienced radiologists and compared with postoperative pathological results. Results: Retropharyngeal lymph node metastasis were confirmed in 54 of 398 (13.6%) cases according to postoperative pathology. The sensitivity and specificity of preoperative enhanced CT in the diagnosis of retropharyngeal lymph node metastasis were 34.6% and 91.1%, respectively, and the overall accuracy was 84.4%. Multivariate logistic regression analysis showed that the site of the primary lesion and pathological N stage were independent risk factors for retropharyngeal lymph node metastasis in hypopharyngeal squamous cell carcinoma. Patients with primary lesion located in the posterior wall of hypopharynx (OR=4.83, 95% CI: 1.27-18.40), N2 stage (OR=6.30, 95% CI: 2.25-17.67), and N3 stage (OR=26.89, 95% CI: 5.76-125.58) were prone to retropharyngeal lymph node metastasis. The 5-year overall survival rate of the 398 patients was 50.4%, and the 5-year disease-free survival rate was 48.3%. Multivariate Cox regression analysis showed that T stage, N stage, retropharyngeal lymph node metastasis, and radiotherapy were independent influencing factors for overall survival (T stage: HR=1.28, 95% CI: 1.06-1.54; N stage: HR=1.26, 95% CI: 1.14-1.40; retropharyngeal lymph node metastasis: HR=2.13, 95% CI: 1.47-3.08; radiotherapy: HR=0.54, 95% CI: 0.38-0.76) and disease-free survival of patients with hypopharyngeal squamous cell carcinoma (T stage: HR=1.26, 95% CI: 1.06-1.51; N stage: HR=1.25, 95% CI: 1.13-1.37; retropharyngeal lymph node metastasis: HR=2.24, 95% CI: 1.56-3.21; radiotherapy: HR=0.55, 95% CI: 0.40-0.77). Conclusions: Metastasis of retropharyngeal lymph nodes in hypopharyngeal squamous cell carcinoma is not rare. Enhanced CT is of low accuracy and limited value in diagnosing retropharyngeal lymph node metastasis. Primary lesions located in the posterior wall of the hypopharyngx, N2 stage, and N3 stage are independent high-risk factors for retropharyngeal lymph node metastasis. The prognosis of hypopharyngeal cancer patients with retropharyngeal lymph node metastasis is worse, and active surgical exploration and clearance can effectively reduce the mortality caused by retropharyngeal lymph node metastasis.

Oligodontia is the congenital absence of six or more teeth and comprises the more severe forms of tooth agenesis. Many genes have been implicated in the etiology of tooth agenesis, which is highly variable in its clinical presentation. The purpose of this study was to identify associations between genetic mutations and clinical features of oligodontia patients. An online systematic search of papers published from January 1992 to June 2021 identified 381 oligodontia cases meeting the eligibility criteria of causative gene mutation, phenotype description, and radiographic records. Additionally, ten families with oligodontia were recruited and their genetic etiologies were determined by whole-exome sequence analyses. We identified a novel mutation in WNT10A (c.99_105dup) and eight previously reported mutations in WNT10A (c.433 G > A; c.682 T > A; c.318 C > G; c.511.C > T; c.321 C > A), EDAR (c.581 C > T), and LRP6 (c.1003 C > T, c.2747 G > T). Collectively, 20 different causative genes were implicated among those 393 cases with oligodontia. For each causative gene, the mean number of missing teeth per case and the frequency of teeth missing at each position were calculated. Genotype-phenotype correlation analysis indicated that molars agenesis is more likely linked to PAX9 mutations, mandibular first premolar agenesis is least associated with PAX9 mutations. Mandibular incisors and maxillary lateral incisor agenesis are most closely linked to EDA mutations.

To investigate the inhibitory effect of sildenafil on Caco-2 cell proliferation and its anti-inflammatory effect on menadione-induced NCM460 cell inflammation model, MTT assay was used to determine cell proliferation. Intracellular reactive oxygen species(ROS)and nitric oxide(NO)levels were detected by fluorescent probe. Western blot was used to detect the expression of eNOS/ERK/JNK pathway related proteins in Caco-2 cells and correlated inflammatory cytokines in NCM460 cells. The effect of sildenafil on the growth of two probiotics was determined by spectrophotometry. Results showed that sildenafil signi-ficantly inhibited the proliferation of Caco-2 cells and enhanced the expression levels of eNOS, p-eNOS, p-JNK1/2 and p-ERK1/2 proteins in Caco-2 cells; while after adding NG-nitro-L-arginine methyl ester(L-NAME), the expression levels of eNOS, p-eNOS, p-JNK1/2 and p-ERK1/2 proteins were significantly lower than those of the sildenafil group. Compared with the menadione group, sildenafil significantly reduced ROS levels in NCM460 cells and inhibited the expression levels of IL-6, IL-1β, p62, and TNF-α. Moreover, high concentrations of sildenafil had no obvious toxic effects on Lactobacillus casei and Lactobacillus rhamnosus. Thus, the results indicated that sildenafil could effectively inhibit the intestinal inflammatory response without affecting the balance of the intestinal flora, and prevent colorectal cancer by reducing the oxidative stress responses in the intestinal cells.
