OBJECTIVE To summarize the current situation of pharmaceutical clinic service in our hospital over the past five years， and explore sustainable development strategies for service models of pharmaceutical clinics. METHODS A retrospective analysis was conducted on the consultation records of patients who registered and established files at the pharmaceutical clinic in our hospital from January 2019 to December 2023. Statistical analysis was performed on patients’ general information， medication- related problems， and types of pharmaceutical services provided by pharmacists. RESULTS A total of 963 consultation records were included， among which females aged 20-39 years accounted for the highest proportion （66.04%）； obstetrics and gynecology- related consultations accounted for the largest number of cases. Additionally， 80 patients attended follow-up visits at our hospital’s pharmaceutical clinic. A total of 1 029 medication-related issues were resolved， including 538 cases of drug consultations （52.28%）， 453 medication recommendations （44.02%）， 22 medication restructuring（2.14%）， and 16 medication education （1.55%）； the most common types of medication-related problems identified were adverse drug events（70.07%）. CONCLUSIONS Although the pharmaceutical clinic has achieved recognition from clinicians and patients， challenges such as low awareness among healthcare providers and the public persist. Future efforts should focus on strengthening information technology construction， enhancing pharmacist training， and establishing various forms of outpatient pharmaceutical service models.

ObjectiveTo evaluate the clinical efficacy and safety of the traditional Chinese medicine （TCM） compound Chaiqin Xiaoyong Decoction （柴芩消痈饮， CXD） combined with Jinhuang Ointment （金黄膏， JO） in treating the nodular stage of acne mastitis of liver meridian heat accumulation type. MethodsA randomized， double-blind， placebo-controlled clinical trial was conducted. A total of 108 patients with liver meridian heat accumulation type acne mastitis in the nodular stage were randomly assigned to a treatment group and a control group， with 54 patients in each group. Both groups received topical application of JO once daily at a thickness of 3~5 mm for 8 hours， along with standard nursing care. On this basis， the treatment group received oral CXD granules， while the control group received placebo granules， administered twice daily， 3 sachets per dose， for 14 consecutive days. Clinical efficacy， TCM symptom scores， nodule size， visual analogue scale （VAS） pain scores， white blood cell （WBC） count， C-reactive protein （CRP） level， and systemic immune-inflammation index （SII） were compared. At the end of treatment， efficacy and safety indicators were evaluated. A 6-month follow-up was conducted to compare the proportion of patients undergoing surgical treatment. ResultsThe total clinical efficacy rate in the treatment group was 90.38% （47/52）， significantly higher than 32.00% （16/50） in the control group （P＜0.01）. The treatment group also showed significantly lower TCM symptom scores， VAS scores， nodule size， WBC count， CRP level， and SII （P＜0.05 or P＜0.01）. During follow-up， the surgical intervention rate in the treatment group was 5.77% （3/52）， lower than 14.00% （7/50） in the control group， with a statistically significant difference （P＜0.01）. No significant abnormalities were observed in safety indicators before and after treatment in either group. ConclusionCXD effectively reduces nodule size and alleviates symptoms such as redness and pain in patients with acne mastitis of liver meridian heat accumulation type， improves TCM symptom scores， enhances overall clinical efficacy， and demonstrates good safety.

Antibiotic adjuvants offer a promising strategy for restoring antibiotic sensitivity, expanding antibacterial spectra, and reducing required dosages. Previously, compound 15 was identified as a potential adjuvant for Polymyxin B (PB) against multidrug-resistant (MDR) Pseudomonas aeruginosa DK2; however, its clinical utility was hindered by high cytotoxicity, uncertain in vivo efficacy, and an unclear synergetic mechanism. To address these challenges, we synthesized and evaluated a series of novel benzamide derivatives, with A22 emerging as a particularly promising candidate. A22 demonstrated potent synergistic activity to PB, minimal cytotoxicity, improved water solubility, and broad-spectrum synergism of polymyxins against various clinically isolated MDR Gram-negative strains. In vivo studies using Caenorhabditis elegans and mouse models further confirmed the efficacy of A22. Moreover, A22 effectively suppressed the development of PB resistance in Pseudomonas aeruginosa DK2. Mechanistic investigations revealed that A22 enhances polymyxins activity by inducing reactive oxygen species production, reducing ATP levels, increasing NOX activity, and inhibiting biofilm formation, leading to bacterial death. These findings position A22 as a highly promising candidate for the development of polymyxin adjuvants, offering a robust approach to combating MDR Gram-negative bacterial infections.

Objective: To compare quality control (relative purity and specific activity) and process control [plasminogen (Pg) antigen recovery and potency recovery] indexes of samples before and after adding the Q chromatography step to the full chromatography process of human Pg, thereby determining whether the addition of this step could improve Pg recovery by affinity chromatography. Methods: A Q chromatography step was added before the Pg affinity chromatography in the original Pg chromatography process. The loading solution, flow through solution and eluate of Q chromatography and Pg affinity chromatography were collected. The potency of coagulation factor Ⅱ (FⅡ), Ⅶ (FⅦ), Ⅷ (FⅧ), Ⅸ (FⅨ), and Ⅹ(FⅩ) were detected by the coagulation method, the total protein content was detected by the BCA method, and the Pg potency was detected by the chromogenic substrate method. The content of specific plasma proteins was detected by immunoturbidimetry, the potency recovery of coagulation factors was calculated, and the flow direction of coagulation factors was analyzed. The recovery of different plasma protein antigens were calculated, and the distribution of impurity proteins was analyzed. The relative purity and specific activity of Pg, antigen content, and potency recovery in the target fractions were calculated and compared with the original process indicators, so as to determine the effect of adding Q chromatography on the original process. Furthermore, the reproducibility after process modification was assessed. Results: 100% of FⅡ, FⅩ, and FⅨ, 87.81% of FⅧ, and 40.44% of FⅦ in filtered plasma were removed by Q chromatography. The residual FⅦ (53.26%) and FⅧ (13.30%) in Q flow-through fraction were completely removed by Pg affinity chromatography. In both the original process (without Q-chromatography) and the modified process (with Q-chromatography), non-target plasma proteins mainly existed in the flow-through fraction of Pg affinity chromatography. The antigen recovery of IgM, ceruloplasmin (CER), and fibronectin (FNC) in Q-chromatography flow-through fraction were reduced. In contrast, antigen recovery of other plasma proteins [IgG, IgA, Pg, albumin (AlB), alpha-1-antitrypsin (AAT), and fibrinogen (Fg)] were all >90%, which were consistent with the protein composition and proportion in the original affinity chromatography loading solution. Compared with the recovery rate of Pg antigen in the original process (74.4%), the total recovery of Pg antigen in the modified process was significantly increased (89.97%). Compared with the recovery of IgG (97.48%) and Fg (95.32%) in the Pg affinity flows-through fraction of the original process, the modified process resulted in a slight reduction in the recovery of IgG (94.60%), while the recovery of Fg was not affected (95.05%). The potency recovery rate, specific activity, and relative purity of Pg after Q chromatography were 99.3%, 0.016 U/mg, and 0.15%. These values were the same as those of Pg affinity chromatography loading solution by the original process, indicating that introduction of Q chromatography did not affect subsequent Pg affinity chromatography. Compared with the recovery of Pg antigen in three batches of the original process (66.49±1.02)%, the recovery of Pg antigen in the affinity chromatography eluent of the modified process [five batches; (77.43±4.43)%] was significantly improved. Furthermore, the potency recovery was (86.80±4.28)%, the relative purity was (81.99±1.25)%, the specific activity was (8.679±1.073)U/mg, and the process was reproducible. Conclusion: The addition of Q chromatography could improve the recovery of Pg affinity chromatography in the full chromatography process.

Objective To investigate the effect of evodiamine(EVO)on retinal injury in diabetic rats by regulating the cyclic adenosine monophosphate(cAMP)/protein kinase A(PKA)signaling pathway.Methods Totally 96 Sprague-Dawley rats(192 eyes)were divided into the negative control(NC)group,Model group,low-dose EVO(EVO-L)group,medium-dose EVO(EVO-M)group,high-dose EVO(EVO-H)group,calcium dobesilate(CD)group,SQ22536 group and EVO-H+SQ22536 group,with 12 rats in each group.Rats in the NC group were intraperitoneally injected with physiological saline instead of streptozotocin,and diabetic retinopathy models were established in all other groups.After successful mod-eling,the drug was administered once a day for 4 weeks.The blood glucose level of rats in each group was measured by blood glucose meter;HE staining was applied to detect the pathological changes of the retina of rats;TUNEL staining was adopted to detect the apoptosis of ganglion cells in the retina of rats;the levels of superoxide dismutase(SOD),malondial-dehyde(MDA),tumor necrosis factor-α(TNF-α),interleukin(IL)-6 and cAMP in the retina of rats were detected;West-em blot was used to detect the protein expressions of Bcl-2 associated X protein(Bax),P53 and phosphorylated protein ki-nase A(p-PKA)in the retina of rats.Results Compared with the NC group,the pathological injury of the retina in the Model group was more serious;the blood glucose,apoptosis rate of retinal ganglion cells,MDA,TNF-α,IL-6,Bax and P53 protein expressions increased,and the SOD,cAMP and p-PKA/PKA protein expression decreased,with statistically significant differences(all P＜0.05).Compared with the Model group,the pathological injury of the retina was relieved,the blood glucose,apoptosis rate of retinal ganglion cells,MDA,TNF-α,IL-6,Bax and P53 protein expressions decreased,and the SOD,cAMP and p-PKA/PKA protein expression increased in the EVO-L group,EVO-M group,EVO-H group and CD group,with statistically significant differences(all P＜0.05).Compared with the Model group,the retinal tissue of the SQ22536 group was severely damaged,the blood glucose,apoptosis rate of retinal ganglion cells,MDA,TNF-α,IL-6,Bax and P53 protein expressions increased,and the SOD,cAMP,p-PKA/PKA protein expression decreased,with statistically significant differences(all P＜0.05).Compared with the EVO-H group,the EVO-H+SQ22536 group showed more serious pathological injury of retinal tissue,increased blood glucose,apoptosis rate of retinal ganglion cells,MDA,TNF-α,IL-6,Bax and P53 protein expressions,and decreased SOD,cAMP and p-PKA/PKA protein expression,and the differences were statistically significant(all P＜0.05).Conclusion EVO may alleviate retinal injury in diabetic rats by activating the cAMP/PKA signaling pathway.

Purpose To explore the value of CT-based radiomics in the preoperative prediction of lymphatic invasion of node-negative gastric cancer,and to construct a nomogram combined with clinical variables.Materials and Methods The clinical and CT imaging data of 173 gastric cancer patients with lymph node negative and pathologically confirmed gastric cancer in the Sir Run Run Shaw Hospital from January 2019 to June 2021 were retrospectively analyzed.A total of 60 cases with lymphovascular invasion(LVI)positive patients and 113 cases with LVI negative patients were included,and randomly divided into train cohort(n=121)and test cohort(n=52)at 7∶3.Based on the train cohort,the clinical model,the radiomics model,the fusion model were constructed and verified in the test cohort.Clinical data and conventional CT features included age,gender,tumor marker,tumor location,tumor morphology,enhancement range,etc.The clinical significant variables were selected through univariate and multivariate analysis to establish the clinical model.The tumor regions of interest were segmented and radiomics features were extracted by using the 3D-Slicer software.Key features were screened through least absolute shrinkage and selection operator regression analysis,and then the radiomics model was constructed with random forest algorithm,and converted to random forest score(RF score).The fusion model was constructed via combining clinical significant variables and RF score,and visualized as a nomogram.The receiver operator characteristic curve and area under curve(AUC)were used to evaluate the prediction performance of the models.Decision curve analysis was used to calculate the clinical practicability.Results The radiomics model was superior to the clinical model.The radiomics model AUC of the train cohort and the test cohort were 0.872(0.810 to 0.935)and 0.827(0.707 to 0.947),the clinical model AUC were 0.767(0.682 to 0.852)and 0.761(0.610 to 0.913).The nomogram further improved the predictive efficiency,the AUC in train cohort and test cohort reached 0.898(0.842 to 0.953)and 0.844(0.717 to 0.971),respectively.Decision curve analysis demonstrated clinical benefits of nomogram.Conclusion The radiomics model can be used to preoperatively predict LVI of node-negative gastric cancer.The nomogram can further improve the prediction efficiency.

Objective To investigate the clinical efficacy of multidisciplinary team (MDT) model combined with Da Vinci robot-assisted thoracic surgery in the treatment of early non-small cell lung cancer (NSCLC). Methods From July 2020 to December 2021, the patients with NSCLC who received Da Vinci robot-assisted thoracic surgery in the Department of Thoracic Surgery, General Hospital of Northern Theater Command were collected. According to whether MDT were performed before hospitalization, the patients were divided into an MDT group and a common group. The recovery and clinical efficacy were compared between the two groups. Results A total of 187 patients were enrolled, including 81 males and 106 females, aged 63 (56, 67) years. There were 85 patients in the MDT group, and 102 patients in the common group. Compared with the common group, the MDT group had lower incidence of postoperative complications (9.4% vs. 29.4%, P=0.017), shorter intraoperative operation time [55 (45, 61) min vs. 79 (65, 90) min, P<0.001], and less intraoperative blood loss [25 (20, 30) mL vs. 30 (20, 50) mL, P=0.029] in the same operation mode. In addition, the drainage volume on the second postoperative day [270 (200, 350) mL vs. 215 (190, 300) mL, P=0.004], the number of dissected lymph nodes groups [6 (5, 6) groups vs. 5 (3, 6) groups, P=0.004] and the number of dissected lymph nodes [16 (13, 21) vs. 13 (9, 20), P=0.005] in the MDT group were significantly better than those in the common group. The differences in the postoperative intubation time and postoperative hospital stay between the two groups were not statistically significant (P>0.05). Conclusion MDT combined with Da Vinci robot-assisted thoracic surgery can further reduce the risk of surgery, improve the clinical treatment effect, reduce the incidence of postoperative complications, and accelerate the rehabilitation of patients.

Objective:To investigate the predictive efficacy of spiral computed tomography(CT)combined with serum fibrinogen(Fbg)detection in the prognosis of patients with locally advanced non-small cell lung cancer(NSCLC)who underwent concurrent radiotherapy and chemotherapy.Methods:From April 2018 to January 2023,a total of 60 patients with locally advanced NSCLC patients,who admitted to Hefei Cancer Hospital of the Chinese Academy of Sciences and underwent the treatment of concurrent radiotherapy and chemotherapy,were selected.They were divided into survival group(50 cases)and endpoint event group(10 cases)according to the prognosis.Before treatment,both two groups were examined by spiral CT,and the average CT values,noise values,and signal to noise ratio(SNR)values of CT related indicators of two groups were counted by using statistical method.The serum Fbg levels of two groups were detected before treatment,and the follow up was conducted until October 2023,and the record of the follow-up time within 9 months were counted by using statistical method.Kaplan-Meier method and Logrank analysis were used to analyze prognosis.The mean CT values,noise values,SNR and Fbg data were included in the binary regression analysis for the receiver operating characteristic(ROC)curve analysis,so as to obtain the efficacy values of each indicator and the combination of the each indicator in predicting prognosis.Results:The average CT value and noise value of the endpoint event group were significantly higher than those of the survival group,while the SNR was significantly lower than that of the survival group,and the serum Fbg level of the endpoint event group was significantly higher than that of the survival group,and the differences were statistically significant(t=5.445,18.323,7.580,78.628,P<0.05),respectively.The area under curve(AUC)values of ROC curve of average CT value,noise value,SNR,Fbg alone and the combination of 4 indicators were 0.665(95%CI:0.493-0.837),0.581(95%CI:0.410-0.752),0.734(95%CI:0.598-0.870),0.668(95%CI:0.533-0.803)and 0.776(95%CI:0.657-0.895)in predicting the prognosis of concurrent radiotherapy and chemotherapy of NSCLC patients,respectively.The ROC curve was adopted to analyze the diagnostic thresholds of the obtained CT value(56.832%),noise value(12.283%),SNR(10.149%)and Fbg(5.102 g/L).Based on the thresholds of each indicator,35 patients with high average CT value and 25 patients with low average CT value were identified.The survival time of patients with high average CT value was significantly lower than that of patients with low average CT value,and the difference was statistically significant(Logrank=25.554,P<0.05).In these patients,37 patients appeared high noise and 23 patients appeared low noise,and the survival time of patients with high noise was significantly lower than that of patients with low noise,and the difference was statistically significant(Logrank=28.109,P<0.05).The survival time of 38 patients with high SNR was significantly higher than that of 22 patients with low SNR,and the difference was statistically significant(Logrank=17.502,P<0.05).The survival time of 26 patients with high Fbg was significantly lower than that of 34 patients with low Fbg,and the difference was significant(Logrank=17.809,P<0.05).Conclusion:The average CT value,noise value and SNR combined with serum Fbg level of the relative indicators of CT scan relate to the prognosis of patients with tumor,and the combined detection of them can predict the prognosis of NSCLC patients undergoing concurrent radiotherapy and chemotherapy.

Hip fracture in the elderly is characterized by high incidence, high disability rate, and high mortality and has been recognized as a public health issue threatening their health. Surgery is the preferred choice for the treatment of elderly patients with hip fracture. However, lower extremity deep venous thrombosis (DVT) has an extremely high incidence rate during the perioperative period, and may significantly increase the risk of patients′ death once it progresses to pulmonary embolism. In response to this issue, the clinical guidelines and expert consensuses all emphasize active application of comprehensive preventive measures, including basic prevention, physical prevention, and pharmacological prevention. In this prevention system, basic prevention is the basis of physical and pharmacological prevention. However,there is a lack of unified and definite recommendations for basic preventive measures in clinical practice. To this end, the Orthopedic Nursing Professional Committee of the Chinese Nursing Association and Nursing Department of the Orthopedic Branch of the China International Exchange and Promotive Association for Medical and Health Care organized relevant nursing experts to formulate Expert consensus on perioperative basic prevention for lower extremity deep venous thrombosis in elderly patients with hip fracture ( version 2024) . A total of 10 recommendations were proposed, aiming to standardize the basic preventive measures for lower extremity DVT in elderly patients with hip fractures during the perioperative period and promote their subsequent rehabilitation.
