OBJECTIVE To explore the willingness to pay （WTP） of Urumqi residents for community pharmacies’ medication guidance services and its influencing factors， so as to provide data support for the optimization of community pharmacy services and the establishment of a fee structure for medication guidance services. METHODS A stratified quota sampling method was employed to select 14 communities in Urumqi City. From April to June 2025， a combined offline and online questionnaire survey was conducted among adult residents in these communities. The contingent valuation method was used to construct three hypothetical scenarios （namely， basic， enhanced and extended services） of medication counselling in community pharmacies to assess residents’ WTP for these services. Binary Logistic regression was employed to analyze the influencing factors of WTP. RESULTS A total of 576 valid questionnaires were obtained. Under the scenarios of basic， enhanced and extended services， 38.54%， 49.65% and 67.19% of the respondents expressed WTP for the services， respectively. Occupational type， type of basic medical insurance， annual income， perception of pharmacists’ profession， and acceptance level of the service were identified as major influencing factors for WTP （P＜0.05）. CONCLUSIONS The willingness of residents in Urumqi to pay for medication counseling services provided by pharmacists in community pharmacies significantly increases with the enrichment of service content. It is recommended to incorporate basic medication counselling services provided by pharmacists in community pharmacies into medical insurance payment， while value-added services should be partially or fully self-paid by residents. Additionally， efforts should be made to strengthen the promotion of the professional and service value of licensed pharmacists， so as to facilitate the high-quality development of pharmaceutical care.

OBJECTIVES: To study the effects of early respiratory training combined with swallowing function training on physical development and neurodevelopment at a corrected gestational age of 6 months in infants with bronchopulmonary dysplasia (BPD). METHODS: A total of 69 BPD infants who could not be fed completely orally were prospectively selected from the Department of Neonatology of Hunan Children's Hospital between January 2018 and January 2021. Based on a random number table, the infants were divided into a conventional group (35 cases) and a training group (34 cases) (with 8 cases lost to follow-up; the final follow-up included 31 cases in the training group and 30 cases in the conventional group). Both groups received routine clinical treatment and care, while the training group additionally received respiratory and swallowing function training until the infants could independently feed orally. The weight, length, Gesell Developmental Schedule (GDS) results, readmission rate, and multiple readmission rate (two or more admissions) were compared between the two groups at a corrected age of 6 months. RESULTS: At corrected gestational age of 6 months, the training group had higher weight, length, and GDS scores in personal-social, language, gross motor, fine motor, and adaptive development compared to the conventional group (P<0.05). The readmission rate and multiple readmission rate were lower in the training group compared to the conventional group (P<0.05). CONCLUSIONS Early respiratory training combined with swallowing function training for BPD infants in a neonatal intensive care unit setting helps improve physical and neurological development and reduces the readmission rate.

Objective : To investigate the effect of laminarin(LAM) on nonproliferative diabetes retinopathy by high throughput sequencing(RNA-seq). Methods : The diabetes model was established by intraperitoneal injection of streptozotocin(STZ), and the effect of LAM on diabetic mice was observed.C57BL/6 mice were randomly divided into three groups: Control group, Model group, and LAM group, with 8 mice in each group. After 8 weeks of modeling, the LAM group received a 4-week intraperitoneal injection of LAM treatment. Changes in blood glucose and body weight of the three groups of mice were recorded, HE staining was performed to examine retinal lesions, and RNA-seq was used to identify differentially expressed genes(DEGs) in diabetic retinopathy(DR) under the action of STZ and LAM. Results : STZ successfully established the model of DR, and LAM reduced the blood sugar in diabetic mice to a certain extent and improved the pathological morphology of retinal structural looseness in diabetic mice. After RNA-seq analysis of DEGs, it was found that there were a total of 214 DEGs in the retina of the Model group mice compared to the Control group. Enrichment analysis revealed that DR could exacerbate the lesions through the PI3K Akt signaling pathway. There were a total of 42 DEGs in the retina of the Model group and LAM group mice, and enrichment showed that LAM improved the lesions through the neutrophil extracellular trap pathway. Early growth response factor 1(Egr1), FBJ osteosarcoma oncogene(Fos), nuclear receptor subfamily 4A member 1(Nr4a1), and salt-induced kinase 1(Sik1) were regulated by STZ, and LAM significantly regulated their expression, which might be closely related to LAM′s treatment of diabetic retinopathy. Conclusion DEGs can exacerbate the severity of diabetic retinopathyviathe PI3K-Akt signaling pathway. LAM can mitigate diabetic retinopathyviathe neutrophil extracellular trap pathway. Egr1, Fos, Nr4a1, and Sik1 are key genes involved in LAM treatment of STZ-induced DR.

Objective:To report the long-term outcomes of Chinese rectal cancer patients after adopting a Watch and Wait (W&W) strategy following neoadjuvant therapy (NAT).Methods:This multicenter, cross-sectional study was based on real-world data. The study cohort comprised rectal cancer patients who had achieved complete or near complete clinical responses (cCRs, near-cCRs) after NAT and were thereafter managed by a W&W approach, as well as a few patients who had achieved good responses after NAT and had then undergone local excision for confirmation of pathological complete response. All participants had been followed up for ≥2 years. Patients with distant metastases at baseline or who opted for observation while living with the tumor were excluded. Data of eligible patients were retrospectively collected from the Chinese Wait-and-Watch Data Collaboration Group database. These included baseline characteristics, type of NAT, pre-treatment imaging results, evaluation of post-NAT efficacy, salvage measures, and treatment outcomes. We herein report the long-term outcomes of Chinese rectal cancer patients after NAT and W&W and the differences between the cCR and near-cCR groups.Results:Clinical data of 318 rectal cancer patients who had undergone W&W for over 2 years and been followed up were collected from eight medical centers (Peking University Cancer Hospital, Fudan University Shanghai Cancer Center, Sun Yat-sen University Cancer Center, Shanghai Changhai Hospital, Peking Union Medical College Hospital, Liaoning Cancer Hospital, the First Hospital of Jilin University, and Yunnan Cancer Hospital.) The participants comprised 221 men (69.4%) and 107 women (30.6%) of median age 60 (26-86) years. The median distance between tumor and anal verge was 3.4 (0-10.4) cm. Of these patients, 291 and 27 had achieved cCR or near-cCR, respectively, after NAT. The median duration of follow-up was 48.4 (10.2-110.3) months. The 5-year cumulative overall survival rate was 92.4% (95%CI: 86.8%-95.7%), 5-year cumulative disease-specific survival (CSS) rate 96.6% (95%CI: 92.2%-98.5%), 5-year cumulative organ-preserving disease-free survival rate 86.6% (95%CI: 81.0%-90.7%), and 5-year organ preservation rate 85.3% (95%CI: 80.3%-89.1%). The overall 5-year local recurrence and distant metastasis rates were 18.5% (95%CI: 14.9%-20.8%) and 8.2% (95%CI: 5.4%-12.5%), respectively. Most local recurrences (82.1%, 46/56) occurred within 2 years, and 91.0% (51/56) occurred within 3 years, the median time to recurrence being 11.7 (2.5-66.6) months. Most (91.1%, 51/56) local recurrences occurred within the intestinal lumen. Distant metastases developed in 23 patients; 60.9% (14/23) occurred within 2 years and 73.9% (17/23) within 3 years, the median time to distant metastasis being 21.9 (2.6-90.3) months. Common sites included lung (15/23, 65.2%), liver (6/23, 26.1%), and bone (7/23, 30.4%) The metastases involved single organs in 17 patients and multiple organs in six. There were no significant differences in overall, cumulative disease-specific, or organ-preserving disease-free survival or rate of metastases between the two groups (all P>0.05). The 5-year local recurrence rate was higher in the near-cCR than in the cCR group (41.6% vs. 16.4%, P<0.01), with a lower organ preservation rate (69.2% vs. 88.0%, P<0.001). The success rates of salvage after local recurrence and distant metastasis were 82.1% (46/56) and 13.0% (3/23), respectively. Conclusion:Rectal cancer patients who achieve cCR or near-cCR after NAT and undergo W&W have favorable oncological outcomes and a high rate of organ preservation. Local recurrence and distant metastasis during W&W follow certain patterns, with a relatively high salvage rate for local recurrence. Our findings highlight the importance of close follow-up and timely intervention during the W&W process.

Objective This study aimed to explore the association of single nucleotide polymorphisms(SNP)in the matrix metalloproteinase 2(MMP-2)signaling pathway and the risk of vascular senescence(VS). Methods In this cross-sectional study,between May and November 2022,peripheral venous blood of 151 VS patients(case group)and 233 volunteers(control group)were collected.Fourteen SNPs were identified in five genes encoding the components of the MMP-2 signaling pathway,assessed through carotid-femoral pulse wave velocity(cfPWV),and analyzed using multivariate logistic regression.The multigene influence on the risk of VS was assessed using multifactor dimensionality reduction(MDR)and generalized multifactor dimensionality regression(GMDR)modeling. Results Within the multivariate logistic regression models,four SNPs were screened to have significant associations with VS:chemokine(C-C motif)ligand 2(CCL2)rs4586,MMP2 rs14070,MMP2 rs7201,and MMP2 rs1053605.Carriers of the T/C genotype of MMP2 rs14070 had a 2.17-fold increased risk of developing VS compared with those of the C/C genotype,and those of the T/T genotype had a 19.375-fold increased risk.CCL2 rs4586 and MMP-2 rs14070 exhibited the most significant interactions. Conclusion CCL2 rs4586,MMP-2 rs14070,MMP-2 rs7201,and MMP-2 rs1053605 polymorphisms were significantly associated with the risk of VS.

Objective To investigate the effects of methionine restriction(MR)on macrophages in lipopolysaccharide(LPS)-induced acute lung injury(ALI)and to explore the underlying mechanism.Methods According to the random number table method,36 male C57BL/6J mice(6～8 weeks old,23±2 g)were divided into 3 groups with 12 mice in each group:the sham group,the LPS group and the LPS+MR group.HE staining and pathological scoring of lung injury were performed in lung tissues.The expression of LPS-binding protein(LBP)and Toll-like receptor-4(TLR4)was detected by RT-qPCR and Western blotting.Macrophage-colony stimulating factor(M-CSF),granulocyte-macrophage-colony stimulating factor(GM-CSF)and chemokine C-C motif ligand 3(CCL3)which are all macrophage-associated chemokines were analyzed by immunohistochemistry.Results Compared with the sham group,the pathological score of lung injury in the LPS group was significantly increased(P＜0.01);The mRNA and protein expression levels of LBP and TLR4 were significantly increased;The number of positive cells of CD11b,F4/80,M-CSF,GM-CSF and CCL3 were significantly increased(P＜0.01).MR significantly improved LPS-induced ALI,and decreased the pathological score of lung injury(P＜0.01);The mRNA and protein expression levels of LBP and TLR4 were decreased;Compared with the LPS group,the number of positive cells of CD11 b,F4/80,M-CSF,GM-CSF and CCL3 were reduced in the LPS+MR group(P＜0.01).Conclusion MR could attenuate LPS-induced ALI by inhibiting the expression of macrophage chemokines and preventing infiltration and activation of macrophage to lungs.

Objective To compare the clinical effects between sutureless bridge intrascleral fixation and ciliary sul-cus suture suspension of intraocular lens(IOL)1 year postoperatively.Methods In this retrospective study,14 patients(14 eyes)who underwent sutureless bridge intrascleral IOL fixation in the No.988 Hospital of Joint Logistic Support Force of PLA from March 2019 to January 2022 were taken as the intrascleral fixation group and 15 patients(15 eyes)who under-went IOL ciliary sulcus suture suspension in the same period were taken as the suture suspension group.During the 1-year follow-up,the preoperative and postoperative uncorrected visual acuity(UCVA),best corrected visual acuity(BCVA)(logMAR),spherical equivalent(SE),endothelial cell count(ECC),intraocular pressure(IOP)and IOL position were compared between the two groups.Results At 1,6 and 12 months postoperatively,the UCVA in both groups significant-ly increased compared with those before surgery(all P＜0.05),and UCVA in the intrascleral fixation group were better than those in the suture suspension group at all postoperative time points(F=4.560,6.411 and5.373;all P＜0.05).At 1,6 and 12 months postoperatively,there was no significant difference in BCVA in both groups compared with those before surgery(all P＞0.05),but BCVA in the intrascleral fixation group were better than those in the suture suspension group at all postoperative time points(F=6.170,6.957 and 10.624;all P＜0.05).After surgery,eyes in the intrascleral fixation group showed hyperopia drift,while eyes in the suture suspension group showed myopia drift.At 1,6 and 12 months post-operatively,the SE of the intrascleral fixation group were(0.59±0.30)D,(0.57±0.27)D and(0.64±0.29)D,respec-tively,and those of the suture suspension group were(-0.75±0.44)D,(-0.72±0.42)D and(-1.12±0.64)D,re-spectively.At 6 months postoperatively,the ECC of both groups were significantly lower than those before surgery(t=8.579 and 21.929;both P＜0.001).The IOP in both groups were within the normal range preoperatively and stable during the follow-up.The IOL were centrally located without obvious decentration or tilt during the follow-up.In addition,there were no vitreous and retinal complications.Conclusion Both sutureless bridge intrascleral IOL fixation and IOL ciliary sulcus suture suspension can obtain a favorable prognosis of visual acuity with refractive shift,while sutureless bridge in-trascleral fixation shows better clinical outcomes.

Objective:To compare the feasibility and safety of a new portable endoscopic system and the conventional endoscopic system for the detection and emergency treatment of abdominal trauma in animal models.Methods:Three healthy Bama pigs, which were fasted and water deprivation for 8 h before surgery and then underwent induction anesthesia. A layer-by-layer incision was made into the abdominal cavity of Bama pigs. An artificial pneumoperitoneum was established using a laparoscopic pneumoperitoneum machine. A bullet model was inserted into the abdominal cavity to build the bullet wound model. After the bullet model was removed, a shrapnel model was inserted into the mid-abdomen to build the shrapnel wound model. The two types of endoscopic system were used to detect, remove bullet model or shrapnel model of the three Bama pigs respectively. The procedure order of the two systems was assigned according to the random number table method. The surgical success, operation time, endoscopy pipeline patency, endoscopic operation satisfaction, adverse events and equipment defects were recorded.Results:Three surgeries were performed using the new portable endoscopic system and three other surgeries using the conventional endoscopic system, all of which were successful. The time of the new portable endoscopic system to find and remove the bullet model, and the shrapnel model were 232.33±11.68 s, 300.33±57.70 s, 170.00±44.44 s and 52.67±2.52 s, respectively. The corresponding time of the conventional endoscopic system were 232.67±21.20 s ( t=-0.054, P=0.962), 256.67±67.00 s ( t=0.880, P=0.472), 176.00±52.42 s ( t=-0.111, P=0.922), 58.67±14.84 s ( t=-0.832, P=0.493), respectively. There was no significant difference between the two systems ( P>0.05). The endoscopy tubes of the two endoscopic systems were both smooth. The operator was satisfied with the endoscopic procedures of both endoscopic systems, and no adverse event or device defect occurred. Conclusion:The portable endoscopic system proves to be safe and feasible for the diagnosis and treatment of abdominal trauma in animal models.
