OBJECTIVE To establish a pharmaceutical management system for externally dispensed medicines in medical institutions， so as to improve medication safety and regulatory efficiency. METHODS Based on policy analysis and hospital practice， a pharmaceutical management system for externally dispensed medicines was constructed by integrating institutional frameworks， an information‑based platform and management procedures， and the management effectiveness was evaluated. RESULTS Our hospital formulated the Regulations on the Management of Externally Dispensed Medicines ， which standardized catalogue selection， prescription issuance， acceptance and use， supervision and evaluation. An information‑based management platform for externally dispensed medicines was built relying on the hospital information system， enabling electronic prescription circulation， intelligent prescription review and whole‑process traceability. Institutional requirements and platform functions were embedded into three core management procedures， namely catalogue selection， prescription issuance， and medicine acceptance and use， forming a closed‑loop working mechanism. After the implementation of the management system， compared with pre‑implementation， the qualified rate of externally dispensed prescriptions increased from 85.2% to 99.3% （ P ＜0.001）， the automatic prescription review pass rate exceeded 95%， the prescription review duration shortened from 7.2 min to 1.8 min （ P ＜0.001）. All dimensional satisfaction scores of patients and medical staff were significantly improved， the standardization awareness of medical staff reached 100%. CONCLUSIONS The construction of a pharmaceutical management system for externally dispensed medicines with standardized institutional frameworks， informatized platforms and standardized procedures effectively enhances the rationality and management efficiency of externally dispensed prescription medicines， and provides a replicable practical pathway for the management of externally dispensed medicines in medical institutions.

Acute kidney injury (AKI) is a clinical syndrome characterized by severe impairment of renal function. The occurrence of AKI often leads to the accumulation of metabolites, electrolyte imbalance, changes in drug concentration gradients, and may even induce systemic inflammatory responses and indirectly affect distal organs, which is one of the reasons for the high mortality rate of AKI. In traditional Chinese medicine, cordyceps sinensis is a widely used natural herb, which is believed to improve kidney injury and promote the recovery of renal tubular function. It contains abundant chemical components, has diverse species, and the distribution, content and efficacy of its active substances also vary. This article reviews the research progress of cordyceps sinensis in the treatment of AKI.

Objective:To simulate and compare the impact of scar contraction force on maxillary alveolar bone displacement after cleft palate surgery in different regions of the palate.Methods:The same scar contraction force was applied to the grouping hard pal-ate area on the original finite element model of the maxilla with cleft palate,and calculations were performed in ANSYS 17.0.Divid-ed into four groups based on the applied force area:anterior half(group 1),posterior half(group 2),lateral half(group 3),and me-dial half(group 4).Nodes in the alveolar bone of the cleft and non-cleft sides were selected as observation points.The three-dimen-sional displacement of observation points was recorded and compared between groups.Results:The displacement of group 1＞group 3,4＞group 2(P＜0.01).Conclusion:Scars from different parts of the hard palate can lead to a decrease in the length,width,and height of the maxillary alveolar bone.Among them,the anterior scar has the most severe impact,followed by the medial and lateral scars,and the posterior scar has the smallest impact.

AIM: To evaluate the safety and efficacy of ultrasonic cycloplasty(UCP)combined with anti-vascular endothelial growth factor(VEGF)+ panretinal photocoagulation(PRP)in the treatment of advanced neovascular glaucoma(NVG).METHODS: Retrospective study. A total of 45 patients(45 eyes)with advanced NVG who received surgery in our hospital from August 2020 to September 2022 were collected and divided into UCP+ anti-VEGF +PRP group(16 patients, 16 eyes), transscleral cyclophotocoagulation(TCP)+anti-VEGF+PRP group(20 patients, 20 eyes), UCP alone group(9 patients, 9 eyes). The intraocular pressure, pain scores, postoperative medication, effective rate, total success rate and the incidence of complications of the patients in the three groups were compared before surgery and at 1 d, 1 wk, 1 and 3 mo after surgery.RESULTS: There was no significant difference in preoperative intraocular pressure, pain scores and preoperative medication of patients in the three groups(all P>0.05). While there were statistical significance in the intraocular pressure and pain scores at 1 d, 1 wk, 1 and 3 mo after surgery(all P<0.01). The intraocular pressure of the UCP alone group(31.78±10.23 mmHg)was found to be higher than that of both the UCP+ anti-VEGF +PRP group(19.44±8.23 mmHg)and the TCP+ anti-VEGF +PRP group(20.80±10.27 mmHg)at 1 mo postoperatively(all P<0.017). The pain score of the TCP+ anti-VEGF +PRP group at 1 d and 1 wk postoperatively was higher than both the UCP+ anti-VEGF +PRP group and the UCP alone group(all P<0.017). The effective rates of UCP+ anti-VEGF +PRP group, TCP+ anti-VEGF +PRP group and UCP alone group were 81%(13/16), 75%(15/20)and 67%(6/9), respectively,(P=0.675), and the success rates were 69%(11/16), 50%(10/20), and 0(0/9), respectively(P=0.003). There was no significant difference in complications of patients in the three groups(P>0.05).CONCLUSION: UCP combined with anti-VEGF +PRP and TCP combined with anti-VEGF +PRP showed comparable efficacy in reducing intraocular pressure in advanced NVG. UCP combined with anti-VEGF+PRP was more effective in relieving pain and with no serious complications in advanced NVG. UCP alone can effectively control intraocular pressure and alleviate the pain of patients in the early postoperative period, but long-term control still requires anti-VEGF+PRP.

Objective:To study the effect of Compound Duzhong Jiangu Granules on joint function, quality of life and inflammatory factors in patients with Kashin-Beck disease.Methods:By group design, 135 patients with Kashin-Beck disease in Chongxin County, Pingliang City, Gansu Province, were selected and divided into intervention group (100 cases treated with Compound Duzhong Jiangu Granules, 12 g/bag, 1 bag/time, 3 times/day, treatment for 1 month) and control group (35 cases treated with ibuprofen, 0.3 g/capsule, 1 capsule/time, 2 times/day, treatment for 2 weeks) according to the randomized, single-blind principle. The changes of joint dysfunction index score, joint function improvement rate, total scores of Kashin-Beck disease quality of life (KBDQOL) and scores of each dimension were analyzed before treatment, 1 month and 3 months after treatment. The serum levels of interleukin-6 (IL-6), nuclear factor κB (NFκB)-p65, inducible nitric oxide synthase (NOS2), nitric oxide (NO), and prostaglandin E2 (PGE2) were detected by enzyme-linked immunosorbent assay before treatment and 1 month after treatment.Results:The total scores of joint dysfunction index of the intervention group and the control group 1 month after treatment and 3 months after treatment were lower than those before treatment, but 3 months after treatment was higher than 1 month after treatment ( P < 0.001). One month after treatment, the total effective rates of joint function improvement in the intervention group and the control group were 68.00% (68/100) and 54.55% (18/33), respectively; 3 months after treatment, the total effective rates of the intervention group and the control group were 36.00% (36/100) and 39.39%(13/33), respectively. The total scores and scores of each dimension of KBDQOL were not significant for the main effect of the group ( P > 0.05), but significant for the main effect at the time point ( P < 0.05), and there was no interactive effect ( P > 0.05). There were significant differences in the scores of social support and mental status dimensions in the intervention group at different time points ( P < 0.001). And in the intervention group, the total score, the scores of physical function, activity limitation, economy and overall health dimensions were statistically significant between before treatment and 1 month after treatment, 1 month after treatment and 3 months after treatment( P < 0.05); however, there was no significant difference between before treatment and 3 months after treatment ( P > 0.05). One month after treatment, the serum PGE2 levels of both groups were decreased ( P < 0.05), and there was no difference in other inflammatory factors at different groups and time points ( P > 0.05). Conclusion:Compound Duzhong Jiangu Granules can effectively inhibit the inflammatory reaction of patients with Kashin-Beck disease, promote the improvement of joint function and improve the quality of life in various aspects.

OBJECTIVE: To explore the role of small nuclear noncoding RNA 7SK in embryonic stem cell (ESCs) proliferation and the value of 7SK as a target for early diagnosis and treatment for primordial dwarfism (PD). METHODS: ESC line R1 was transfected with the CRISPR/Cas9 system, and sequencing of the PCR product and glycerol gradient analysis were performed to identify novel 7SK deletion mutations. A lentivirus system was used to knock down cyclin-dependent kinase 9 (CDK9) in clones with 7SK deletion mutations, and the effect of CDK9 knockdown on the protein level of cell division cycle 6 (CDC6) was analyzed with Western blotting. RESULTS: We identified a novel deletion mutation of 7SK at 128-179 nt in the ESCs, which resulted in deficiency of cell proliferation. 7SK truncation at 128-179 nt significantly reduced the protein expressions of La-related protein 7 (LARP7) and CDC6. CONCLUSIONS 7SK truncation at 128-179 nt can significantly impair proliferation of ESCs by downregulating CDC6. 7SK is a key regulator of proliferation and mediates the growth of ESCs through a mechanism dependent on CDK9 activity, suggesting the value of 7SK truncation at 128-179 nt as a potential target for early diagnosis and treatment of PD.
