Objective To analyze the problems of review of anti-tumor drug prescriptions and medical orders assisted by an information system to improve the review rules,and to provide a reference for improving review quality of anti-tumor drug prescription.Methods The problem with the pre-review of anti-tumor drug prescriptions and medical orders assisted by the information system in Sichuan Cancer Hospital during 2020-2022 were collected.The data came from the MEDICOM PASS system in Sichuan Cancer hospital.Clinical pharmacists made comments on relevant problems and analyzed the results.Results A total of 9 325 antitumor drug pre-approval problems,including 6 279 outpatient prescriptions(67.3%)and 3 046 inpatient orders(32.7%),among which 6 153(66.0%)were unsuitable indications,1 933(20.7%)were drug contraindications,449(4.8%)were problematic routes of administration,345(3.7%)were unsuitable drug compatibility,177(1.9%)were inappropriate drug frequency,133(1.4%)were problematic drug populations,74(0.8%)were unsuitable single doses,39(0.4%)were unacceptable drug interactions,22(0.2%)were unsuitable drug total.The results of clinical pharmacists'comments were 4 459 reasonable cases,with a false positive rate of 47.8%.The false positive problems included 2 264(50.8%)cases of unsuitable indications,1 933(43.3%)cases of drug contraindications,231(5.2%)cases of problematic routes of administration,and 31(0.7%)cases of unsuitable populations.Conclusion The review of anti-tumor drug prescriptions assisted by an information system can effectively intercept irrational drug use and improve the review quality of prescriptions and medical orders.However,the evidence-based medicine date of antitumor drugs is updated quickly.Pharmacists should constantly improve the prescription review rules based on the latest evidence-based medicine data.
摘要
BACKGROUND:Scoliosis mainly refers to sequence abnormalities in the coronal,sagittal,and axial positions of the spine,with a Cobb angle of≥10°.The patients may experience symptoms such as unequal shoulder height and back asymmetry.Severe cases may affect the patient's cardiopulmonary function,thereby affecting their daily life.Conservative treatment can control the progression of scoliosis and avoid later surgery.Scoliosis orthosis is currently a commonly used and effective treatment measure in conservative treatment. OBJECTIVE:To summarize and analyze the current research status,hotspots,and trends of scoliosis orthoses both domestically and internationally,providing reference for related research. METHODS:Using bibliometrics and visual analysis as tools,and using a comparison between China and foreign countries as a method,this paper analyzes the literature on scoliosis orthosis journals in the past decade.Based on bibliometrics,the current status of research on scoliosis orthoses is determined.Citespace software is used to analyze key words and identify the current hotspots and future trends in scoliosis orthosis research. RESULTS AND CONCLUSION:(1)At present,the number of literature on scoliosis orthoses is still on a fluctuating upward trend.China and the United States are the main countries for research,with a literature share of over 40%.However,the average citation rate of foreign language literature by Chinese scholars is relatively low.(2)The basic fields of domestic research are mainly surgery and pediatrics,while orthotics and clinical neurology are mainly studied abroad.Among them,there is also a certain number of documents in domestic Chinese medicine,indicating that China is also engaged in the combination of Chinese and Western treatment of scoliosis.The National Natural Science Foundation of China has the highest proportion in the aspect of Chinese and foreign literature,reflecting the importance of the fund attaches to the research of scoliosis orthosis.(3)The authors with the highest number of publications are Qiu Yong and Negrini Stefano,and the most published institutions are the Spinal Surgery Department of Gulou Hospital affiliated to Nanjing University Medical College and UDICE-French Research University.Domestic and foreign authors and institutions have certain communications about this,but not closely,which requires relevant institutions and scholars to further explore and study.(4)From the research hotspots and future trends,the main treatment type is adolescent idiopathic scoliosis,while the production method of the short-column side bending orthosis is three-dimensinoal printing,and the main treatment index is convex progression.The ultimate purpose of treatment is to improve the quality of life of the patients.

Objectives: To investigated the safety and efficacy of treating patients with acute non-ST-segment elevation myocardial infarction (NSTEMI) and elevated levels of N-terminal pro-hormone B-type natriuretic peptide (NT-proBNP) with levosimendan within 24 hours of first medical contact (FMC). Methods: This multicenter, open-label, block-randomized controlled trial (NCT03189901) investigated the safety and efficacy of levosimendan as an early management strategy of acute heart failure (EMS-AHF) for patients with NSTEMI and high NT-proBNP levels. This study included 255 patients with NSTEMI and elevated NT-proBNP levels, including 142 males and 113 females with a median age of 65 (58-70) years, and were admitted in the emergency or outpatient departments at 14 medical centers in China between October 2017 and October 2021. The patients were randomly divided into a levosimendan group (n=129) and a control group (n=126). The primary outcome measure was NT-proBNP levels on day 3 of treatment and changes in the NT-proBNP levels from baseline on day 5 after randomization. The secondary outcome measures included the proportion of patients with more than 30% reduction in NT-proBNP levels from baseline, major adverse cardiovascular events (MACE) during hospitalization and at 6 months after hospitalization, safety during the treatment, and health economics indices. The measurement data parameters between groups were compared using the t-test or the non-parametric test. The count data parameters were compared between groups using the χ² test. Results: On day 3, the NT-proBNP levels in the levosimendan group were lower than the control group but were statistically insignificant [866 (455, 1 960) vs. 1 118 (459, 2 417) ng/L, Z=-1.25,P=0.21]. However, on day 5, changes in the NT-proBNP levels from baseline in the levosimendan group were significantly higher than the control group [67.6% (33.8%,82.5%)vs.54.8% (7.3%,77.9%), Z=-2.14, P=0.03]. There were no significant differences in the proportion of patients with more than 30% reduction in the NT-proBNP levels on day 5 between the levosimendan and the control groups [77.5% (100/129) vs. 69.0% (87/126), χ²=2.34, P=0.13]. Furthermore, incidences of MACE did not show any significant differences between the two groups during hospitalization [4.7% (6/129) vs. 7.1% (9/126), χ²=0.72, P=0.40] and at 6 months [14.7% (19/129) vs. 12.7% (16/126), χ²=0.22, P=0.64]. Four cardiac deaths were reported in the control group during hospitalization [0 (0/129) vs. 3.2% (4/126), P=0.06]. However, 6-month survival rates were comparable between the two groups (log-rank test, P=0.18). Moreover, adverse events or serious adverse events such as shock, ventricular fibrillation, and ventricular tachycardia were not reported in both the groups during levosimendan treatment (days 0-1). The total cost of hospitalization [34 591.00(15 527.46,59 324.80) vs. 37 144.65(16 066.90,63 919.00)yuan, Z=-0.26, P=0.80] and the total length of hospitalization [9 (8, 12) vs. 10 (7, 13) days, Z=0.72, P=0.72] were lower for patients in the levosimendan group compared to those in the control group, but did not show statistically significant differences. Conclusions: Early administration of levosimendan reduced NT-proBNP levels in NSTEMI patients with elevated NT-proBNP and did not increase the total cost and length of hospitalization, but did not significantly improve MACE during hospitalization or at 6 months.

ObjectiveTo investigate the mechanism of Yiqi Huoxue Tongluo prescription （YHTP） in the treatment of diabetic neuropathic pain （DNP）. MethodNinety SPF-grade SD male rats were randomized into blank， model， low- （2.25 g·kg-1）， medium- （4.5 g·kg-1）， and high-dose （9 g·kg-1） YHTP， and mecobalamin （0.175 mg·kg-1） groups. Except those in the blank group， the rats in the remaining 5 groups were fed with a high-fat and high-glucose diet and subjected to intraperitoneal injection of low-dose （35 mg·kg-1） streptozotocin （STZ） to establish the model of DNP. The sciatic nerve conduction velocity in DNP rats was measured by the neurophysiological method， and the levels of interleukin-6 （IL-6）， IL-1β， and tumor necrosis factor-α （TNF-α） were measured by enzyme-linked immunosorbent assay （ELISA）. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was employed to measure the mRNA levels of glial fibrillary acidic protein （GFAP） and extracellular signal-regulated kinase （ERK） in the spinal cord. Western blot was employed to measure the protein levels of GFAP and phosphorylated ERK （p-ERK）， and immunofluorescence staining to measure the fluorescence intensity of GFAP and p-ERK in the spinal cord. In the cell experiments， 100 mmol·L-1 high glucose was used to induce the activation of astrocytes （CTX-TNA2） for the modeling of nerve cell injury. The cells were randomized into the normal， model， drug-containing serum （10% YQHT）， inhibitor ［10 mol·L-1 corynoxeine （COR）］， drug-containing serum + inhibitor （10% YHTP + 10 mol·L-1 COR） groups. The levels of pro-inflammatory factors （TNF-α and IL-1β） and the anti-inflammatory factor IL-10 in CTX-TNA2 cells were determined by ELISA， and the protein levels of GFAP and p-ERK in CTX-TNA2 cells by Western blot. ResultThe animal experiments showed that compared with the blank group， the model group presented reduced mechanical withdrawal threshold （MWT）， thermal work limit （TWL）， and nerve conduction velocity， elevated levels of fasting blood glucose， IL-1β， TNF-α， and IL-6， and up-regulated protein levels of GFAP and p-ERK， and mRNA levels of ERK1， ERK2， GFAP （P<0.01）. Compared with model group， YHTP increased the MWT， TWL， and sciatic nerve conduction velocity （P<0.01）， lowered the levels of IL-1β， TNF-α， and IL-6 （P<0.01）， and down-regulated the protein levels of GFAP and p-ERK， and mRNA levels of ERK1， ERK2， GFAP in the spinal cord （P<0.05， P<0.01）. The cell experiments showed that compared with the blank group， the model group had decreased survival rate， elevated levels of pro-inflammatory factors， and up-regulated protein levels of ERK and GFAP （P<0.01）. Compared with the model group， the YHTP-containing serum lowered the levels of IL-1β and TNF-α （P<0.05， P<0.01）， elevated the level of IL-10 （P<0.01）， and down-regulated the protein levels of ERK and GFAP （P<0.01）. ConclusionYHTP may inhibit the activation of astrocytes by inhibiting the ERK signaling pathway to reduce inflammation and thus relieve DNP.
摘要
Objective: To investigate the clinicopathological features, immunophenotype, ultrastructure, genetic alterations and prognosis of succinate dehydrogenase-deficient renal cell carcinoma (SDH RCC). Methods: A total of 11 SDH RCCs, diagnosed from 2010 to 2019, were selected from the Department of Pathology of Nanjing Jingling Hospital, Nanjing University School of Medicine for clinicopathologic, immunohistochemical (IHC), ultrastructural investigation and follow-up. The molecular features of seven cases were analyzed by the panel-targeted DNA next generation sequencing (NGS). Results: There were seven males and four females, with ages ranging from 24 to 62 years (mean 41.4 years, median 41 years). Microscopically, SDH RCC was mainly composed of solid and tubular structures with local cystic change. Four cases showed nested or trabecular structure distributed in a loose hypocellular connective tissue or around scar, similar to oncocytoma. The neoplastic cells demonstrated flocculent eosinophilic cytoplasm with typical intracytoplasmic vacuoles. Immunohistochemically, eight cases were negative for SDHB; three cases showed focal and weak expression, whereas normal renal tubular and vascular endothelial cells demonstrated strong cytoplasmic staining. NGS of DNA targeted-panel detected pathogenic mutations of SDHB gene in seven cases (including three cases with equivocal IHC expression of SDHB), without any mutations in other SDH related genes. There were four cases of SDHB missense mutation, one case of frameshift mutation, one case of splicing mutation, and one case of acquired stop codon mutation. Conclusions: SDH RCC is a distinct variant of RCCs with genetic tendency or with hereditary cancer syndrome. NGS is recommended to detect the related gene mutations for a definitive diagnosis. The patients should be closely followed up.

Objective: To investigate the immunohistochemical expression of NKX3.1 and NKX2.2 in mesenchymal chondrosarcoma (MC), and to explore the differential diagnostic value of NKX3.1 and NKX2.2 in MC and other types of small round cell malignant tumors. Methods: A total of 12 cases of MC and 97 other small round cell malignant tumors diagnosed in Jinling Hospital, Nanjing University School of Medicine from 2001 to 2020 were collected for NKX3.1 and NKX2.2 immunohistochemical detection. Among them, two kinds of NKX3.1 antibodies [rabbit polyclonal antibody and rabbit monoclonal antibody (EP356)] were used for detection in 12 cases of MC, and one NKX3.1 antibody (rabbit polyclonal antibody) was detected in 97 cases of other small round cell malignant tumors, and the relevant literature was reviewed. Results: The 12 MC patients included 7 females and 5 males, with a mean age of 33 years (14-54 years). Nine cases were from bone and three from soft tissue. Among the 12 MC patients, 8 patients had postoperative recurrence or metastasis, and 3 of them died of tumor recurrence or metastasis. Histologically, 12 cases of MC showed typical bidirectional differentiation.The positive rate of both NKX3.1 antibodies in MC was 12/12, NKX3.1 was focal weakly positive in only one of 12 chondrosarcomas (grade 3), 5 alveolar rhabdomyosarcomas, 5 embryonal rhabdomyosarcomas, and 5 solitary fibrous tumors, respectively. The remaining 70 cases of other small round cell malignant tumors were negative. The positive rates of NKX2.2 in MC, Ewing sarcoma and olfactory neuroblastoma were 12/12, 15/15 and 4/5, respectively. In 12 cases of chondrosarcoma (grade 3), 5 cases of poorly differentiated synovial sarcoma, 5 cases of alveolar rhabdomyosarcoma, and 5 cases of solitary fibrous tumor, NKX2.2 was focally and weakly positive in only one case, respectively, and all the remaining 50 cases of other small round cell malignant tumors were negative. Conclusions: The expression of NKX3.1 and NKX2.2 proteins are significant indicators in the diagnosis of MC, and the combined detection of NKX3.1 and NKX2.2 can help distinguish MC from most other small round cell malignant tumors.

The paper summarizes the valuable experience of the famous teachers of all generations in the teaching & research room of meridians and acupoints of Beijing University of CM. The shortcomings are presented when the acupoints are explained in accordance with the flowing route of meridians in classroom teaching of Science of Meridians and Acupoints. Hence, it is proposed that the acupoint names should be interpreted specially for the acupoints distributed on the same meridians or adjacent ones. It is suggested to emphasize the correlation of each acupoint with its adjacent ones from the perspective of the cultural connotation of acupoint names, and then, the differences and similarities in their clinical indications can be analyzed. Eventually, a new approach to the classroom teaching of Science of Meridians and Acupoints may be provided to guide the excavation of traditional cultural connotation and establish the cultural self-confidence and professional identity.

Neuropathic pain is one of the common complications of diabetes. Tetrahydropalmatine(THP) is a main active component of Corydalis Rhizoma with excellent anti-inflammatory and pain-alleviating properties. This study aims to investigate the therapeutic effect of THP on diabetic neuropathic pain(DNP) and the underlying mechanism. High-fat and high-sugar diet(4 weeks) and streptozotocin(STZ, 35 mg·kg~(-1), single intraperitoneal injection) were employed to induce type-2 DNP in rats. Moreover, lipopolysaccharide(LPS) was used to induce the activation of BV2 microglia in vitro to establish an inflammatory cellular model. Fasting blood glucose(FBG) was measured by a blood glucose meter. Mechanical withdrawal threshold(MWT) was assessed with von Frey filaments, and thermal withdrawal latency(TWL) with hot plate apparatus. The protein expression levels of OX42, inducible nitric oxide synthase(iNOS), CD206, p38, and p-p38 were determined by Western blot, the fluorescence expression levels of OX42 and p-p38 in the dorsal horn of the rat spinal cord by immunofluorescence, the mRNA content of p38 and OX42 in rat spinal cord tissue by qRT-PCR, and levels of nitric oxide(NO), interleukin-1β(IL-1β), interleukin-6(IL-6), tumor necrosis factor-α(TNF-α), interleukin-10(IL-10), and serum fasting insulin(FINS) by enzyme-linked immunosorbent assay(ELISA). RESULTS:: showed that the mo-del group demonstrated significant decrease in MWT and TWL, with pain symptoms. THP significantly improved the MWT and TWL of DNP rats, inhibited the activation of microglia and p38 MAPK signaling pathway in rat spinal cord, and ameliorated its inflammatory response. Meanwhile, THP promoted the change of LPS-induced BV2 microglia from the pro-inflammatory M1 phenotype to the anti-inflammatory M2 phenotype, suppressed the activation of the p38 MAPK signaling pathway, decreased the expression levels of inflammatory factors NO, IL-1β, IL-6, and TNF-α, and increased the expression level of anti-inflammatory factor IL-10. The findings suggested that THP can significantly ameliorate the pain symptoms of DNP rats possibly by inhibiting the inflammatory response caused by M1 polarization of microglia via the p38 MAPK pathway.

Objective@#To explore the role of rejection sensitivity in the relationship between the psychological resilience and social adaptability of college students with left behind experience, so as to provide reference for college students to beffer adapt to the society.@*Methods@#Self designed questionnaire, the Conor Davidson Resilience Scale(CD-RISC), the Chinese College Students Adaptation Scale(CCSAS), and the Rejection Sensitivity Questionnaire (RSQ) were administered among 3 418 college students from four universities in Anhui Province with the stratified cluster sampling method. This research investigation used AMOS version 21.0 to construct a structural equation model of rejection sensitivity, psychological resilience, and social adaptability, to analyze the mediation effect.@*Results@#There were 1 324 college students with lefe behind experience. Compared with college students without left behind experience[(64.47±13.79)(197.90±25.57)(10.86±2.98)], students with left behind experience exhibited lower levels of psychological resilience, social adaptability, and rejection sensitivity[(63.26±13.69)(195.14±24.60)(10.45±2.91)](t=-2.50, -3.12, -3.87, P<0.05); Rejection sensitivity was negatively associated with social adaptability, and psychological resilience among college students with left behind experience(r=-0.24, -0.22, P<0.01), while social adaptability was positively correlated with psychological resilience(r=0.64, P<0.01). The results of the mediation model showed that psychological resilience affected the mediation path of social adaptability by rejection sensitivity (mediation effect value=0.02, 95%CI=0.01-0.05, P<0.05).@*Conclusion@#Left behind experience had a negative impact on the psychological resilience and social adaptability of undergraduates. With respect to the psychological resilience of undergraduates with left behind experience, rejection sensitivity played a mediating role in the social adaptability relationship.

Background@#Coracoacromial ligament transfer is the traditional procedure for treating chronic acromioclavicular separation, but it is significantly inferior to ligament reconstruction according to biomechanical and clinical studies. However, ligament reconstruction carries the risk of complications of graft loosening and peri-tunnel fractures. Currently, there is no ligament reconstruction procedure optimal for preventing such complications. The purpose of this study was to describe and retrospectively analyze the clinical and radiological outcomes of a “duo-figure-8” autogenic graft wrapping technique, which was used to concomitantly reconstruct the acromioclavicular and coracoclavicular ligaments. @*Methods@#Preoperative, immediate postoperative, and final follow-up oputcomes were evaluated in 10 enrolled patients. Radiographic outcomes were indicated by the bilateral difference of the coracoclavicular distance (CCD) and overlapping length of the acromioclavicular joint (OLac). Quality of reduction was classified into 4 grades according to bilateral CCD difference into overreduction ( 8 mm). Clinical outcomes were evaluated using the American Shoulder and Elbow Surgeons (ASES) and Constant scores. @*Results@#The mean side-to-side differences for CCD were 11.9 mm (preoperative), −0.1 mm (immediate postoperative), and 3.4 mm (final follow-up); those for OLac were 9.4 mm (preoperative) and 2.7 mm (final follow-up). CCD and OLac outcomes significantly improved at final follow-up (p < 0.05). At the immediate postoperative stage, 6 and 4 patients had overreduction and anatomic reduction, respectively. At final follow-up, 7 and 3 patients had anatomic reduction and partial loss of reduction, respectively. The magnitude of improvement of ASES scores for patients with anatomic reduction and partial loss of reduction (p = 0.20) was 18.1 and 20.0, respectively. The magnitude of improvement of Constant scores in patients with anatomic reduction and partial loss of reduction (p = 0.25) was 19.9 and 22.3, respectively. @*Conclusions@#The technique yielded acceptable functional outcomes in patients with anatomic reduction or partial loss of reduction. The “duo-figure-8” wrapping method—a single autogenic tendon graft passing beneath the coracoid process with a tendonknot fixation over the distal clavicle and looping around the acromion intramedullary—did not increase the risk of peri-tunnel fractures over the clavicle, coracoid process, or acromion.

Objective:Taking zebrafish embryos as research model, to investigate the toxic effect of different polar fractions of Euphorbiae Pekinensis Radix before and after processing with vinegar on heart. Method:Zebrafish embryos with normal development at 12 h after fertilization were treated with petroleum ether, dichloromethane and ethyl acetate extracts of Euphorbiae Pekinensis Radix before and after processing with vinegar for observation of cardiac development and function at 72 h. Result:Various polar fractions of Euphorbiae Pekinensis Radix before and after processing with vinegar had the cardiotoxicity on zebrafish embryos in a dose-dependent manner. In addition, the cardiotoxicity of different polar fractions was followed by petroleum ether, dichloromethane and ethyl acetate. The cardiotoxicity was mainly manifested as slow cardiac development, pericardial edema, decrease of heart rate and apoptosis of cardiac cells. Compared with the corresponding polar fraction of raw products, the cardiotoxicity of the same polar fraction of vinegar-processed products with similar doses decreased. Conclusion:Euphorbiae Pekinensis Radix has cardiotoxicity to zebrafish embryos and the cardiotoxicity is reduced after processing with vinegar, which can provide some experimental basis for further elucidation of the detoxication mechanism of Euphorbiae Pekinensis Radix processed with vinegar.
摘要
Carbon monoxide (CO) is an important chemical gas messenger molecule in the body with anti-inflammatory activity. As an active substance in gaseous state, the method for its safe and effective delivery towards the lesion sites remains to be established. Based on the natural affinity of carbon monoxide to hemoglobin, a main component of red blood cells (RBCs), this study proposes a carbon monoxide-red blood cell (CO-RBC) composite system, and tested its therapeutic effect against lung injury in an animal model. The mouse model of septic lung injury was adopted, and the carbon monoxide release molecule (CORM-2) was used as a positive control. CO-RBC system was characterized by CO release, stability, toxicity and in vivo lung targeting. The expression of intercellular adhesion molecule (ICAM-1) and pulmonary surfactant protein-A (SP-A) were evaluated in the animal model and the therapeutic effect of CO-RBC system for sepsis was measured by inflammatory factors tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6), as well as survival time of mice and pathological changes of the lung. Our results show that CO-RBC system exhibited satisfactory stability with negligible CO release during 48 h storage under nitrogen protection, while the CO release was about 70% within 12 h under physiological condition, in contrast to CO burst release from CORM-2. The CO-RBC system showed no significant toxicity in the animal model, and in vivo fluorescence imaging results showed effective accumulation in the lungs, supporting its lung targeting effects. The secretion of TNF-α and IL-6 in the CO-RBC group was significantly lower than that in other groups, the degree of pulmonary interstitial edema was relieved, the white blood cell infiltration was decreased, and the survival rate was significantly improved. Therefore, the CO-RBC system has a significant inhibitory effect on the pulmonary inflammatory response in septic mice compared with CORM-2. This system provides a new hope for therapeutic treatment of sepsis.
摘要
To study the effects of different fraction of Euphorbiae Pekinensis Radix before and after processing with vinegar on liver and gastrointestinal toxicity of zebrafish embryos,the zebrafish embryos after fertilized 12 h(12 hpf) were exposed to different concentrations of solution until 96 h(96 hpf),for observation of the toxicity response of the liver and gastrointestinal of individual zebrafish embryos. The results showed that toxicity increased in a dose-dependent manner. The liver and gastrointestinal toxicity of the zebrafish embryos in various polar fractions of Euphorbiae Pekinensis Radix before and after processing with vinegar was mainly manifested as slow liver development,smaller liver area,edema of yolk sac,delayed absorption,slowing of gastrointestinal motility,abnormal function of gastrointestinal goblet cell secretion. In addition,the toxicity of different polarity was followed by petroleum ether,dichloromethane,ethyl acetate. The above results indicated that the toxicity was reduced after processing with vinegar,and the fractions of petroleum ether and methylene chloride were the main sites responsible for liver and gastrointestinal toxicity.
