OBJECTIVE To construct a closed-loop management model for externally dispensed intravenous prescriptions， and to provide reference for standardized management of externally dispensed intravenous prescriptions. METHODS Based on the Expert Consensus on Closed-loop Management of Externally Dispensed Intravenous Prescriptions in Guangxi Zhuang Autonomous Region previously formulated by our hospital， risk points during the entire process were systematically identified through multidisciplinary team brainstorming and a fishbone diagram. A series of strategies were subsequently formulated and implemented， including qualifying designated external dispensing pharmacies and the drug catalogs， operating and maintaining the hospital information system and the Pharmacy Intravenous Admixture Service （PIVAS） intelligent management platform， and strengthening differentiated training for staff in the whole workflow. A whole-process closed-loop management system was constructed with PIVAS as the co re hub and the daytime chemotherapy center as the safety terminal. RESULTS A total of 3 cooperating pharmacies and an initial drug list comprising 35 product specifications were selected. A closed‑loop management process encompassing hospital outpatient prescribing， patient drug purchase in designated pharmacies， PIVAS drug dispensing， and medication use in daytime chemotherapy center was successfully established. This system enabled the mandatory grouping and association of externally dispensed intravenous prescriptions with in-hospital diluents， full-process verification based on drug traceability codes， intelligent monitoring of infusion parameters， and whole-process data traceability. CONCLUSIONS The constructed model effectively resolves the coordination and safety oversight during the use of externally dispensed intravenous drugs from out-of-hospital circulation to in-hospital use， and has preliminarily enabled procedural standardization， whole-process information traceability， and proactive control of medication risks.

Background Prolonged vibration exposure can lead to vascular endothelial cell dysfunction and cellular injury. However, research on the association between vibration and ferroptosis in vascular endothelial cells remains insufficient. Objective To explore whether occupational vibration exposure is associated with alterations in serum markers related to ferroptosis in patients with hand-arm vibration disease (HAVD), and to further investigate, through in vitro cell experiments, whether vibration exposure may induce ferroptosis in vascular endothelial cells. Methods ①A judgmental sampling method was employed to select 50 workers with HAVD (the HAVD group), 50 vibration-exposed workers without HAVD (the vibration exposure group), and 50 non–hand-transmitted vibration-exposed workers (the control group). Serum iron levels, malondialdehyde (MDA) content, and superoxide dismutase (SOD) levels were measured using serum iron assay kits, MDA detection kits, and SOD detection kits, respectively. One-way analysis of variance and binary logistic regression analysis were performed to examine the relationships between these indicators and HAVD. ②Human umbilical vein endothelial cells (HUVEC) were divided into a vibration group and a control group. The vibration group was subjected to vibration at 120 Hz with an acceleration of 6.5 m·s⁻² and further subdivided into four subgroups: 1 d 2 h, 1 d 4 h, 2 d 2 h, and 2 d 4 h. The control group was treated identically except for vibration exposure. Cellular iron (Fe²⁺) content and reduced glutathione (GSH) levels in HUVEC were measured using ferrous iron colorimetric assay kits and GSH colorimetric assay kits, respectively, to assess the effects of different vibration exposure schedules. Real-time quantitative polymerase chain reaction (RT-qPCR) was performed to detect the mRNA expression levels of ferroptosis-related genes, including acyl-CoA synthetase long-chain family member 4 (ACSL4), tumor suppressor protein P53 (P53), ferritin heavy chain 1 (FTH1), and glutathione peroxidase 4 (GPX4). Western blot analysis was conducted to determine the protein expression levels of ferroptosis-related markers in HUVEC. Results ①Compared with the control group, the patients in the HAVD group showed increased serum iron and MDA levels, along with decreased SOD levels (P<0.05). The logistic regression analysis indicated that elevated serum iron levels were significantly associated with an increased risk of HAVD (OR=4.034; 95%CI: 2.063, 7.887), and elevated MDA levels were also associated with an increased risk of HAVD (OR=1.523; 95%CI: 1.026, 1.936). ②Compared with the control group, increased intracellular Fe²⁺ content and decreased GSH content were observed in HUVECs in the 1 d 4 h and 2 d 4 h vibration subgroups (P<0.05). The RT-qPCR results showed that, compared with the control group, vibration exposures of 1 d 4 h and 2 d 4 h significantly upregulated the expression of ACSL4 and P53 (P<0.05), whereas the mRNA expression levels of GPX4 and FTH1 were downregulated in all vibration-exposed endothelial cells (P<0.05). The Western blot results revealed that, compared with the control group, the vibration exposure schedules of 1 d 2 h and 1 d 4 h significantly upregulated the protein expression levels of ACSL4 and P53 (P<0.05), while the vibration exposure schedules of 1 d 4 h, 2 d 2 h, and 2 d 4 h significantly downregulated the protein expression levels of FTH1 and GPX4 (P<0.05). Conclusion Occupational vibration exposure is associated with alterations in iron metabolism and oxidative stress status in workers with HAVD. The in vitro experiments further demonstrates that vibration stimulation induces intracellular iron accumulation and reduces antioxidant capacity in vascular endothelial cells, accompanied by dysregulated expression of ferroptosis-related molecules. These findings suggest that ferroptosis may play a role in vibration-induced vascular injury and the pathogenesis of HAVD.

Objective On the basis of the theory of the tumor metastatic state, this work aims to explore the metastasis trajectories and peripheral immune response patterns in patients with non-small cell lung cancer (NSCLC) receiving vital qi-strengthening and toxin-eliminating therapy (Fuzheng Juandu) and reveal the value of peripheral immunity in assessing vital qi deficiency during metastasis. Methods A retrospective study design was adopted. Patients with NSCLC admitted from January 1, 2018, to October 31, 2025 were enrolled. Data on metastasis status and peripheral immune indices were collected at the follow-up time points of one, two, three, and five years. Group-based trajectory modeling was used to fit metastasis trajectories, and the independent predictors of trajectory grouping were analyzed through multifactor and multiclassification logistic regression. Results A total of 184 patients with NSCLC were included, and three different groups of metastasis trajectories were identified, namely, the low-risk stable (46.74%, n=86), low-risk rising (13.59%, n=25), and high-risk stable (39.67%, n=73) groups. Univariate analysis revealed substantial differences in peripheral immune indices among the three trajectory groups. Multivariate analysis showed that TNM stage, absolute neutrophil count, lymphocyte count, absolute monocyte count, platelet volume, SAA:CRP ratio, and NLR were independent predictors of the low-risk rising group, whereas TNM stage, absolute monocyte count, basophil count, SII, and NLR were independent predictors of the high-risk stable group. Conclusion Under Fuzheng Juandu therapy, patients with NSCLC exhibit three distinct metastasis trajectories, each corresponding to a specific peripheral immune response pattern. Elucidating these peripheral immune response patterns may facilitate the objective quantification of the degree of vital qi deficiency, prediction of future metastasis risk, and providing an important reference for the individualized clinical implementation of Fuzheng Juandu therapy.

AIM To study the effect of Zuogui Pills on improving ovarian function in rats with premature ovarian failure(POF)by regulating autophagy.METHODS Seven rats were randomly selected as the blank group,and the remaining rats were injected with cisplatin(4.0 mg/kg)intraperitoneally to establish POF model.The success of the model was evaluated by observing the changes of estrous cycle.Twenty-one successful model of rats were randomly divided into model group and estradiol group(0.01 mg/mL)and Zuogui Pills group(1.85 g/kg),with 7 rats in each group,the drug was administered continuously for 21 days.Serum E2,FSH and LH levels were detected by ELISA;HE staining was used to observe the pathological morphology of ovarian tissue;immunohistochemical(IHC)method was used to detect the protein expressions of LC3B,SIRT1 and FoxO1 in ovarian tissues;RT-qPCR method was used to detect the mRNA expressions of LC3B,Beclin-1 and Atg5 in ovarian tissues;the protein expressions of SIRT1,FoxO1 and Ac-FoxO1 in ovarian tissue was detected by Western blot.RESULTS Compared with the blank group,the ovarian index of the model group decreased(P＜0.01);serum FSH and LH levels increased(P＜0.01)and E2 level decreased(P＜0.01);the structure of ovary is disordered,especially atresia follicle;the mRNA expressions of LC3B,Beclin-1 and Atg5 in ovarian tissue increased(P＜0.01),while the protein expressions of LC3B and Ac-FoxO1 increased(P＜0.01),while the protein expressions of SIRT1 and FoxO1 decreased(P＜0.01).Compared with the model group,the ovarian index of rats in estradiol group and Zuogui Pills group increased(P＜0.01);serum FSH and LH levels decreased(P＜0.01)and E2 level increased(P＜0.01);the number of primordial follicles in ovary increased and the number of atresia follicles decreased;the mRNA expressions of LC3B,Beclin-1 and Atg5 in ovarian tissue decreased(P＜0.01),while the protein expressions of LC3B and Ac-FoxO1 decreased(P＜0.01),while the protein expressions of SIRT1 and FoxO1 increased(P＜0.01).CONCLUSION Zuogui Pills may inhibit autophagy by activating SIRT1/FoxO1 signaling pathway,thus improving the pathological state of POF rats,regulating the level of sex hormones in rats,restoring endocrine balance,enhancing ovarian reserve function,promoting the normal development of follicles and delaying the progress of POF.

Objective:To analyze the feasibility and safety of laparoscopic transhepatic section biliary exploration without T-tube drainage in the treatment of intrahepatic and extrahepatic bile duct stones.Methods:A retrospective analysis was conducted on the clinical data of 200 patients with intrahepatic and extrahepatic bile duct stones who underwent surgical treatment in Ankang Central Hospital from January 2020 to December 2024, including 79 males and 121 females, with the average age of (64.1±6.1) years. Among the 200 patients, 100 underwent laparoscopic hepatectomy and stone removal through transhepatic section cholangiography and choledochoscopy and were included in the observation group. Another 100 patients underwent laparoscopic hepatectomy, common bile duct incision, choledochoscopic exploration and stone removal, and T-tube drainage and were included in the control group. The intraoperative blood loss, operation time, postoperative hospital stay, hospitalization cost, postoperative pain score, time to get out of bed and move around, recovery time of intestinal function, abdominal drainage time, total complication rate, recurrence of stones, biliary tract infection, etc. were compared between the two groups.Results:The operation time, intraoperative blood loss, postoperative hospital stay and hospitalization cost of the observation group (165.8±29.9 min, 158.9±23.7 ml, 8.8±1.8 d and 46, 037.8±312.6 yuan, respectively) were all lower than those of the control group (220.3±37.5 min, 232.5±36.7 ml, 12.5±2.5 d, and 57 006.2±528.5 yuan) and the differences were statistically significant (all P<0.05). The postoperative pain score of the control group was (4.8±1.3) points, the postoperative time to get out of bed for activities was (1.6±0.5) d, the postoperative recovery time of intestinal function was (3.2±0.7) d, and the abdominal drainage time was (5.0±0.8) d. All were higher than those of the observation group (3.2±0.8) points, (0.8±0.2) d, (1.8±0.5) d, and (2.5±0.6) d, and the differences were statistically significant (all P<0.05). The total incidence of complications, recurrence of stones and infection rate of biliary tract in the observation group were 6.0%(6/100), 3.0%(3/100) and 2.0%(2/100) respectively, which were lower than those in the control group at 36.0%(36/100), 11.0%(11/100) and 9.0%(9/100). The differences were all statistically significant (all P<0.05). Conclusion:Laparoscopic transhepatic section biliary exploration without T-tube drainage for the treatment of intrahepatic and extrahepatic bile duct stones is feasible and safe.

Severe open tibiofibular fractures account for approximately 28.1% of all open fractures. Among them, Gustilo-Anderson type IIIB/C fractures present significant clinical challenges due to associated bone and soft tissue defects, high infection rates, and risk of amputation. Inadequate preoperative assessment may lead to suboptimal emergency surgical planning or intraoperative complications. Historically, external fixation was often preferred, but this approach has been associated with limitations such as restricted joint mobility, delayed bone union, joint stiffness, and disuse osteoporosis, resulting in poor functional recovery. With advancements of debridement techniques, standardization of antibiotic use, and popularization of early soft tissue coverage, early internal fixation has gained broader acceptance. Nevertheless, controversies persist regarding the choice of fixation method, timing of definitive fixation, use of reamed versus unreamed intramedullary nailing, and necessity of fibular fixation. To standardize the diagnosis and early management of severe open tibiofibular fractures, reduce complication rates, and improve functional recovery, the Society of Microsurgery of the Chinese Medical Association organized a panel of domestic experts to develop the Evidence-based guideline for the diagnosis and early fixation of severe open tibiofibular fractures ( version 2025), using evidence-based methodology. The guidelines provided 12 recommendations covering diagnostic and early fixation strategies of severe open tibiofibular fractures, aiming to provide clinicians with scientifically grounded and standardized guidance.

Objective:To investigate the correlation between long-term statin use and Helicobacter pylori( Hp)infection in the elderly, and to compare the effects of rosuvastatin combined with bismuth-containing quadruple therapy for Hp eradication on lipid levels in elderly patients with mixed hyperlipidemia. Methods:A retrospective analysis was conducted on 1 181 elderly patients with hyperlipidemia, cardiovascular and cerebrovascular diseases, and peripheral arterial disease who were treated at the First Hospital of Lanzhou University between March 2019 and December 2023.According to the results of carbon 14 urea breath test(C 14-UBT), the subjects were divided into the Hp infection group and the non- Hp infection group.Multivariate logistic regression methods were used to analyze the correlation between Hp infection and statin use.A prospective case-control analysis was conducted on 109 patients with mixed hyperlipidemia and Hp infection treated during the same period, they were treated with rosuvastatin combined with bismuth-containing quadruple therapy for Hp eradication.The successful eradication people were selected as the eradication group (n=95). Patients with hyperlipidemia and Hp infection unwilling eradication was selected as the control group (n=109), and treated with rosuvastatin.Changes in lipid levels were compared over a consecutive 6-month period. Results:The overall Hp infection rate was 53.94%(637/1 181). Univariate analysis showed that the infection rate in women was higher than in men.Body mass index(BMI), low-density lipoprotein cholesterol(LDL-C), fasting blood glucose(FBG)levels in the Hp(+ )group were higher than in the Hp(-)group.Long-term low-dose aspirin users had a higher infection rate than non-users.The infection rate was lower in statin users than in non-users[42.65%(374/877) vs.55.59%(169/304), χ2=15.234, P<0.001]. Multivariate analysis showed that women had a higher infection risk than men ( OR=1.441, 95% CI: 1.102-1.729, P=0.011). Higher FBG and LDL-C levels increased the risk of Hp infection ( OR=1.406, 95% CI: 1.271-2.286, P<0.001, OR=1.118, 95% CI: 1.017-1.387, P=0.010). Aspirin use increased the risk of Hp infection( OR=1.162, 95% CI: 1.034-1.294, P=0.021), while statin use reduced the risk of Hp infection ( OR=0.177, 95% CI: 0.018-0.311, P<0.001). The Hp eradication rate was 87.16%(95/109). At 1-and 2-months post-eradication, statistically significant differences were observed between the eradication and control groups in LDL-C, total cholesterol(TC), changes from baseline, and target achievement rates(all P<0.05). At 1-month post-eradication, a statistically significant difference was observed in high-density lipoprotein cholesterol(HDL-C) levels between the two groups.Additionally, at both 1-and 2-months post-eradication, significant differences were found in the changes in HDL-C levels from baseline between the eradication group and the control group(all P<0.05). Conclusions:Long-term statin use in the elderly may reduce the risk of Hp infection.Rosuvastatin combined with a standard quadruple therapy does not improve the Hp eradication rates in elderly patients with mixed hyperlipidemia, but it facilitates short-term achievement of cholesterol targets.
