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 investigate the processing technology of calcined Haematitum based on the concept of quality by design（QbD） and to assess its health risk. MethodsTaking whole iron content， Fe²⁺ dissolution content and looseness as critical quality attributes（CQAs）， and calcination temperature， calcination time， spreading thickness and particle size as critical process parameters（CPPs） determined by the failure mode and effect analysis（FMEA）， the processing technology of calcined Haematitum was optimized by orthogonal test combined with analytic hierarchy process-criteria importance through intercriteria correlation（AHP-CRITIC） hybrid weighting method. The contents of heavy metals and harmful elements were determined by inductively coupled plasma mass spectrometry， and the health risk assessment was carried out by daily exposure（EXP）， target hazard quotient（THQ） and lifetime cancer risk（LCR）， and the theoretical value of the maximum limit was deduced. ResultsThe optimal processing technology for calcined Haematitum was calcination at 650 ℃， calcination time of 1 h， particle size of 0.2-0.5 cm， spreading thickness of 1 cm， and vinegar quenching for 1 time［Haematitum-vinegar（10：3）］. The contents of 5 heavy metals and harmful elements in 13 batches of calcined Haematitum were all decreased with reductions of up to 5-fold. The cumulative THQ of 2 batches of samples was>1， while the cumulative THQ of all batches of Haematitum was>1. The LCR of As in 1 batches of Haematitum was 1×10^-6-1×10^-4， and the LCR of the rest was<1×10^-6， and the LCRs of calcined Haematitum were all<1×10^-6， indicating that the carcinogenic risk of calcined Haematitum was low， but special attention should still be paid to Haematitum medicinal materials. Preliminary theoretical values of the maximum limits of Cu， As， Cd， Pb and Hg were formulated as 1 014， 25， 17， 27， 7 mg·kg^-1. ConclusionThe optimized processing technology of calcined Haematitum is stable and feasible， and the contents of heavy metals and harmful elements are reduced after processing. Preliminary theoretical values of the maximum limits of Cu， As， Cd， Pb and Hg are formulated to provide a scientific basis for the formulation of standards for the limits of harmful elements in Haematitum.

Objective:To investigate the medical narrative competence of pediatric staff, and analyze its influencing factors and correlation with psychological resilience, and to discuss strategies to improve narrative competence.Methods:From January 11 to February 25, 2022, by convenience sampling, we sampled pediatric personnel and those on refresher training at Children's Hospital, Zhejiang University School of Medicine for a questionnaire survey involving general information, the narrative competence scale, and the 14-item resilience scale. With the use of SPSS 26.0, the narrative competence of different populations was compared, and factors affecting narrative competence were determined through Pearson correlation analysis and multiple regression analysis.Results:A total of 361 valid questionnaires were included in this study, and there was significant differences in the narrative competence score between different ages, professional titles, working years, income levels, and whether they wrote parallel charts ( P<0.05). The total score of narrative competence of pediatric staffs was (147.13±18.76), and positively correlated with the total resilience score and the score of each dimension ( P≤0.001). The regression analysis showed that writing parallel charts and resilience could explain 53.10% of the variation in narrative competence ( P<0.001). Conclusions:Pediatric staff's narrative competence is at low or intermediate levels. Parallel chart writing and resilience training can improve narrative competence and promote a harmonious doctor-patient relationship.

Objective:To understand the incidence trend and temporal distribution of breast cancer and reproductive system cancers in women in different age groups and areas in China from 2006 to 2017.Methods:Based on the incidences of breast cancer, vulvar cancer, vaginal cancer, cervical cancer, uterine corpus cancer, and ovarian cancer in women, average age at diagnosis and cases in different age groups and areas in China were calculated, standardized through world population. Software Joinpoint 4.5.0.1 was used to calculate average annual percent of change (AAPC).Results:Between 2006 and 2017, the overall age-standardized incidence rate (ASIR) of the six cancers showed an increasing trend from 39.48/100 000 to 51.11/100 000 (AAPC=2.24%, 95% CI: 1.59%-2.89%). The increasing trend was more obvious in rural area (AAPC=4.65%,95% CI:3.67%-5.64%), whereas no significant increase was observed in urban area (AAPC=0.15%,95% CI:-0.26%-0.56%). Except uterine corpus cancer, the incidences of 5 cancers showed increasing trends. The incidences of cervical cancer showed similar upward trends in urban and rural areas. In urban area, the ASIRs of breast cancer, vaginal cancer and vulvar cancer showed no significant increase, while in rural area it showed significant increase. The ASIR of ovarian cancer showed a decreasing trend in urban area and an increasing trend in rural area. The average age at diagnosis increased for all the cancers, except uterine corpus cancer. However, after standardizing through world population, the increases in the standardized average age at diagnosis were observed only in cervical cancer and vaginal cancer from 49.11 and 55.15 years to 52.13 and 58.81 years, respectively. Conclusions:The overall ASIR of breast cancer and reproductive system cancers in women showed increase trend in China in 2006-2017, and the increase trend was more obvious in rural area than in urban area. Meanwhile, the accessibility to medical facilities in rural area needs to be improved to ensure medical care, early diagnosis and early treatment for the purpose of bridging the gap in female cancer incidence between rural area and urban area.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To evaluate the clinical efficacy of single-wide-tunnel endoscopic submucosal dissection with single-clip-line traction (W-ESTD) for the treatment of early esophageal cancer and precancerous lesions with large area (≥ 3/4 circumference).Methods:A retrospective analysis was performed on patient data of large early esophageal cancer or precancerous lesions treated with digestive endoscopy at the Affiliated Huai'an NO.1 People's Hospital of Nanjing Medical University from January 2018 to January 2023. Patients were divided into W-ESTD group and endoscopic submucosal double-tunnel dissection (D-ESTD) group based on the technique used. Surgical speed, en bloc resection rate, R0 resection rate, curative resection rate, intraoperative and postoperative complications were compared between the two groups.Results:A total of 44 patients with large early esophageal cancer or precancerous lesions were included in this study, including 23 cases in the W-ESTD group and 21 cases in the D-ESTD group. There was no statistically significant difference in baseline data between the two groups ( P>0.05). The operating speeds of W-ESTD and D-ESTD groups were 29.97±11.89 mm2/min and 22.65±6.30 mm2/min, respectively, with significant difference ( t=2.580, P=0.014). There was no statistically significant difference between the two groups in terms of en bloc resection rate [95.7% (22/23) VS 100.0% (21/21), P=1.000], R0 resection rate [87.0% (20/23) VS 90.5% (19/21), P=1.000], or curative resection rate [73.9% (17/23) VS 85.7% (18/21), P=0.462]. No recurrence occurred. Intraoperative muscular injury occurred in 3 cases in the W-ESTD group and 5 cases in the D-ESTD group, and postoperative esophageal stricture occurred in 11 cases and 8 cases respectively, with no significant differences between the two groups ( P>0.05). Conclusion:Compared to D-ESTD, W-ESTD can significantly improve surgical speed and demonstrate itself as a safe and effective approach for treating large early esophageal cancer and precancerous lesions.

Astrocytes (ASTs) and oligodendroglial lineage cells (OLGs) are major macroglial cells in the central nervous system. ASTs communicate with each other through connexin (Cx) and Cx-based network structures, both of which allow for quick transport of nutrients and signals. Moreover, ASTs interact with OLGs through connexin (Cx)-mediated networks to modulate various physiological processes in the brain. In this article, following a brief description of the infrastructural basis of the glial networks and exocrine factors by which ASTs and OLGs may crosstalk, we focus on recapitulating how the interactions between these two types of glial cells modulate myelination, and how the AST-OLG interactions are involved in protecting the integrity of the blood-brain barrier (BBB) and regulating synaptogenesis and neural activity. Recent studies further suggest that AST-OLG interactions are associated with myelin-related diseases, such as multiple sclerosis. A better understanding of the regulatory mechanisms underlying AST-OLG interactions may inspire the development of novel therapeutic strategies for related brain diseases.

METHODS Retrieved from PubMed， the Cochrane Library， Web of Science， Embase， Wanfang， CNKI， CBM and VIP database， randomized controlled trial （RCT） and cohort study about 24 h continuous pump （trial group） versus intermittent infusion （control group） of amphotericin B were collected from the inception to Jan. 2023. After literature screening and data extraction， the quality of RCT was evaluated with modified Jadad scale， and the quality of cohort study was evaluated with Newcastle-Ottawa scale. Meta-analysis and sensitivity analysis were performed by using RevMan 5.4 software. RESULTS A total of 7 literature were included， involving 1 RCT and 6 cohort studies with a total of 767 patients. The results of meta-analysis showed that the clinical effective rate [RR＝1.44， 95%CI （1.13，1.83）， P＝0.003] of trial group was significantly higher than that of control group， and all-cause mortality rate [RR＝0.37， 95%CI（0.19，0.72），P＝0.003] and the incidence rate of infusion reaction [RR＝0.28，95%CI（0.18，0.43）， P＜0.000 01] were significantly lower than control group； there was no statistical significance in the incidence rate of renal impairment between 2 groups [RR＝0.71，95%CI（0.45，1.11），P＝0.13] . The sensitivity analysis results showed that the results obtained in this study were robust. CONCLUSIONS The efficacy and safety of 24 h continuous pump of amphotericin B are better than those of intermittent infusion in the treatment of invasive fungal infection.

Pellionia scabra belongs to the genus Pellionia in the family of Urticaceae, and is a high-quality wild vegetables with high nutritional value. In this study, high-throughput techniques were used to sequence, assemble and annotate the chloroplast genome. We also analyzed its structure, and construct the phylogenetic trees from the P. scabra to further study the chloroplast genome characteristics. The results showed that the chloroplast genome size was 153 220 bp, and the GC content was 36.4%, which belonged to the typical tetrad structure in P. scabra. The chloroplast genome encodes 130 genes, including 85 protein-coding genes, 37 tRNA genes, and 8 rRNA genes in P. scabra. Among them, 15 genes contained 1 intron, 2 genes contained 2 introns, and rps12 had trans-splicing, respectively. In P. scabra, chloroplast genomes could be divided into four categories, including 43 photosynthesis, 64 self-replication, other 7 coding proteins, and 4 unknown functions. A total of 51 073 codons were detected in the chloroplast genome, among which the codon encoding leucine (Leu) accounted for the largest proportion, and the codon preferred to use A and U bases. There were 72 simple sequence repeats (SSRs) in the chloroplast genome of P. scabra, containing 58 single nucleotides, 12 dinucleotides, 1 trinucleotide, and 1 tetranucleotide. The ycf1 gene expansion was present at the IRb/SSC boundary. The phylogenetic trees showed that P. scabra (OL800583) was most closely related to Elatostema stewardii (MZ292972), Elatostema dissectum (MK227819) and Elatostema laevissimum var. laevissimum (MN189961). Taken together, our results provide worthwhile information for understanding the identification, genetic evolution, and genomics research of P. scabra species.
