Case analysis of a patient with osimertinib-induced interstitial pneumonia who re-used EGFR-TKI therapy / 中国药房

OBJECTIVE To explore the way to re-use epidermal growth factor receptor-tyrosine kinase inhibitors （EGFR-TKI） in patients with EGFR-TKI-induced interstitial pneumonia （IP）， using osimertinib as an example. METHODS The IP treatment regimen and re-use of EGFR-TKI regimen in a patient who developed IP after the use of osimertinib were analyzed. And a literature review was made by combining the characteristics of the cases which reported in the literature and the characteristics of this case. RESULTS The patient’s IP symptoms due to treatment with osimertinib had resolved after treatment. The patient’s IP symptoms also did not worsen after using almonertinib in combination with hormones as re-use of EGFR-TKI regimen. However， almonertinib was discontinued as the patient experienced disease progression. The adverse reactions of IP needed to be dealt with in time， the EGFR-TKI should be discontinued and symptomatic treatment should be given. CONCLUSIONS EGFR-TKI targeted therapy could be re-selected by replacing EGFR-TKI， adjusting the dose of EGFR-TKI， and using hormones in combination. EGFR-TKI-induced adverse drug reactions of IP are rare， but need to be observed closely. If other EGFR-TKI is used， close monitoring of adverse reactions and curative effects are also required in order to adjust the patient’s treatment plan in time.

Application of Ortho-Bridge Combination System in the treatment of ulnar impaction syndrome with ulna-shortening osteotomy / 中华创伤骨科杂志

Objective:To investigate the clinical outcomes of Ortho-Bridge Combination System (OBCS) to achieve precise ulna-shortening osteotomy (USO) in the treatment of ulnar impaction syndrome.Methods:A retrospective study was conducted to analyze the 25 patients with ulnar impaction syndrome who had been treated at Institute of Orthopedic Trauma Research, The 920th Hospital of Joint Logistic Support Force of Chinese People's Liberation Army between January 2020 to March 2022. The patients all underwent USO using OBCS. They were 14 females and 11 males with an age of (43.2 ± 10.1) years. Their CT scans were retrieved for preoperative planning and design of a personalized USO. Intraoperatively, OBCS was fixated to the ulna before USO. After the bone was resected according to preoperative planning, the gap between the osteotomy sites was closed with compression, and OBCS was finally fixated with locking screws. The time for bone union after resection, complications, range of motion and grip strength were recorded. The clinical outcomes were evaluated by visual analogue scale (VAS) and Mayo wrist score.Results:All patients completed their operations successfully using OBCS. Their follow-up time was (13.5 ± 1.2) months. The ulnar variation was corrected and osteotomy ends got united in all patients, without nonunion, angulation, or rotation. The wrist VAS significantly decreased from 6.0 (5.0, 6.5) points before operation to 2.0 (1.0, 2.0) points at the last follow-up ( P<0.05). At the last follow-up, the Mayo wrist score [(85.4 ± 8.9) points], grip strength [(39.4 ± 1.2) kg], wrist flexion-extension (111.9° ± 12.6°), wrist pronation-supination (133.2° ± 15.7°), and ulnar radial deviation (35.3° ± 2.8°) were significantly increased compared with the preoperative values [(69.2 ± 13.3) points, (31.3 ± 5.2) kg, 102.0° ± 16.0°, 128.0° ± 15.5°, and 32.2° ± 2.8°] ( P<0.05). Conclusion:In the treatment of ulnar impaction syndrome, OBCS can facilitate the process of USO, correct ulnar variance, and avoid complications like rotation and angulation to improve functions of the wrist.

Experimental study of percutaneous transhepatic implantation of recoverable fiducial marker in Cyberknife tracking therapy / 中华放射医学与防护杂志

Objective:To evaluate the feasibility of a novel liver fiducial marker implantation method for internal fixation and removal of rabbit livers, in order to use in Cyberknife tracking therapy.Methods:Experiments were conducted in vivo and in vitro. In the in vivo experiment, three fiducial markers were implanted percutaneously in each liver of ten rabbits under anesthesia, and the fourth fiducial marker with an external catheter and fixed thin wire was implanted ten days later. After the reference group (the first and the second maker), and the casing group (the first and the fourth marker) were respectively registered and tracked with the Cyberknife, the implantation success rate, registration accuracy, and removal safety of fiducial markers were assessed. The tensile test was performed using liver in vitro by measuring the resistance required to dislodge the spring coil fiducial markers and the fiducial markers without spring coil from liver. Results:The intrahepatic catheter implantation and removal of fiducial marker in rabbit liver had a success rate of 100% and no distant migration. The operation-related and postoperative complications were not occurred. All fiducial markers were successfully traced. Compared to the reference group, the casing group had slightly higher translational errors in supero-inferior and antero-posterior directions ( Z=-11.77, -4.57, P<0.05), and lower translational errors in left-right direction ( Z=-2.52, P<0.05). The dislodgement forces for spring coil fiducial markers was (2.23±0.85) N, significantly different with (0.81±0.13) N for fiducial markers without spring coil ( Z=- 2.31, P < 0.05). Conclusions:The spiral coil structure provides superior fixation in the punctured needle channel, the thin line limits the distant displacement of the fiducial marker outside the liver, and the catheter establishes a channel for the removal. The general operation is simple and easy.

Influence of gut microbiota-derived trimethylamine N-oxide on early neurological deterioration in diabetic patients with acute ischemic stroke / 中华老年医学杂志

Objective:To investigate the influence of trimethylamine N-oxide(TMAO)on the development of early neurological deterioration(END)in diabetic patients with acute ischemic stroke.Methods:In this cross-sectional study, 108 type 2 diabetes patients with acute ischemic stroke treated at the Department of Neurology in the Affiliated Wuxi People’s Hospital of Nanjing Medical University between October 2019 and November 2020 were consecutively recruited.END was defined as an increase in the National Institutes of Health Stroke Scale(NIHSS)≥ 2 points and exclusion of intracranial hemorrhage or bleeding transformation in cranial imaging evaluation within 5 days of initial deterioration of neurological dysfunction.The patients were divided into 2 groups, an END(n=36)group and a non-END group(n=72). Fasting plasma TMAO was measured using isotope dilution liquid chromatography coupled to tandem mass spectrometry.Results:Of the 108 patients, 36(33.3%)were diagnosed with END, and their plasma TMAO levels were significantly higher compared with patients without END( Z=-3.500, P<0.001). For prediction of END, the area under the ROC curve for plasma TMAO levels was 0.707(95% CI: 0.603-0.811, P<0.001). The frequencies of END in subjects grouped via tertiles of TMAO were 22.2%, 19.4% and 58.3%, respectively, with significant differences between the 3 groups( χ2=14.979, P=0.001). Univariate analysis showed that elevated TMAO( OR=1.160, 95% CI: 1.050-1.282, P=0.004)was associated with END.A multivariate logistic regression model further confirmed the association between TMAO and END( OR=1.145, 95% CI: 1.033-1.269, P=0.010). Conclusions:Increased plasma TMAO levels are associated with END in diabetic patients with acute ischemic stroke.

Risk signal mining of ixazomib based on the database of FAERS / 中国药房

OBJECTIVE To explore the risk signal of ixazomib and provide a reference for clinically rational drug use. METHODS The Open Vigil 2.1 online tool was used to extract the data of adverse drug events （ADE） reported by the database of FDA adverse event reporting system （FAERS） from the launch of ixazomib in America （November 20th， 2015） to the latest update of the Open Vigil website （March 31st， 2023）. The data were mined by using the proportional reporting ratio （PRR） and Bayesian confidence propagation neural network （BCPNN） of the proportional imbalance method. The signals were coded by system organ class （SOC） and preferred term （PT） according to MedDRA v25.1. RESULTS A total of 13 841 ADE reports with ixazomib as the “primary subject” were extracted， involving slightly more male patients （49.53%）， and most of them were 65 years old and above （72.48%）； the reports came from 57 countries/regions， mainly America （52.90%）. A total of 186 positive signals were excavated， with 51 high-intensity， 99 medium-intensity， and 36 low-intensity signals， involving 19 SOCs. The top 50 PT in frequency and signal intensity of PRR included neuropathy peripheral （414 cases， high-intensity signal）， platelet count decreased （379 cases， high-intensity signal）， thrombocytopenia （360 cases， high-intensity signal）， cytopenia （75 cases， high-intensity signal） and neurological symptoms （41 cases， high-intensity signal）. SOC involved included nervous system disorders， investigations， and blood and lymphatic system disorders. ADE occurred most frequently in gastrointestinal diseases （2 588 cases）， including diarrhea （1 077 cases， high-intensity signal）， nausea （737 cases， medium-intensity signal）， vomiting （459 cases， medium-intensity signal）， constipation （275 cases， medium-intensity signal）， and so on. The positive signals of infections and infestations contained the largest number of PTs， and most of them were not recorded in the drug instruction， including 12 high-intensity signals （1 030 cases） and 30 medium-intensity signals （627 cases）， which were mainly distributed in lung infection， upper respiratory infection， gastrointestinal infection， sepsis， herpes zoster and so on. The signals of cardiac amyloidosis （7 cases， high-intensity signal） and acute coronary syndrome （14 cases， high-intensity signal） of cardiac disorders and renal dysfunction （91 cases， medium-intensity signal） of renal and urinary disorders were all strong and had not been recorded in the drug instruction. CONCLUSIONS In addition to routine attention to the common ADE of ixazomib in gastrointestinal diseases，nervous system disorders and blood and lymphatic system disorders， clinical attention should also be paid to various infections that may occur during the treatment of patients， and the occurrence of cardiovascular toxicity and renal dysfunction should be monitored.

Objective:To analyze the value of dual energy CT parameters combined with serum procollagen Ⅰ N-terminal propeptide (PⅠNP) and beta C-terminal cross-linked telopeptide of type Ⅰ collagen (β-CTX) in differential diagnosis of spinal bone metastasis from lung cancer and myeloma.Methods:The clinical data of 54 patients with spinal bone metastasis from lung cancer and 50 patients with myeloma in Jincheng People′s Hospital from October 2019 to March 2021 were analyzed retrospectively. All patients were examined by dual energy CT on the day of admission, and the CT values at the energy levels of 40 to 80 keV (energy interval of 10 keV) were recorded. The serum PⅠNP and β-CTX levels were detected by chemiluminescent assay before treatment. The pathological examination results were taken as gold standard, and the CT values at the energy levels of 40 to 80 keV by dual energy CT and serum PⅠNP and β-CTX levels were compared between 2 groups. Receiver operating characteristic (ROC) curve was used to analyze the differential diagnosis value of the CT values at the energy levels of 40 to 80 keV, serum PⅠNP and β-CTX levels alone and combination.Results:The CT values at the energy levels of 40 to 80 keV by dual energy CT and serum PⅠNP and β-CTX levels in patients with spinal bone metastasis from lung cancer were significantly higher than those in patients with myeloma: 79.86 (61.20, 116.32) HU vs. 58.29 (46.92, 64.03) HU, 64.48 (50.27, 90.08) HU vs. 45.78 (38.59, 56.75) HU, 57.35 (43.31, 78.04) HU vs. 43.62 (36.91, 54.06) HU, 52.05 (42.98, 75.79) HU vs. 41.26 (32.84, 51.76) HU, 45.52 (38.55, 63.59) HU vs. 36.68 (28.72, 49.83) HU, 66.35 (31.15, 81.97) μg/L vs. 31.38 (27.76, 34.50) μg/L and 0.61 (0.48, 0.67) μg/L vs. 0.49 (0.47, 0.52) μg/L, and there were statistical differences ( P<0.05 or <0.01). ROC curve analysis result showed that the sensitivity of the combination of the CT values at the energy levels of 40 to 80 keV by dual energy CT was higher than those alone (83.33% vs. 59.26%, 61.11%, 62.96%, 64.81% and 66.67), the area under the curve (AUC) was also higher than those alone (0.882 vs. 0.798, 0.811, 0.817, 0.801 and 0.773), and there were statistical differences ( P<0.01 or <0.05); the sensitivity of the combination of serum PⅠNP and β-CTX levels was higher than those alone (81.48% vs. 57.41% and 62.96%), the AUC was higher than those alone (0.829 vs. 0.753 and 0.729), and there were statistical differences ( P<0.01 or <0.05); the sensitivity of all indexes combined in the differential diagnosis of spinal bone metastasis from lung cancer and myeloma was higher than those of the combination of the CT values at the energy levels of 40 to 80 keV by dual energy CT, the combination of serum PⅠNP and β-CTX levels (98.15% vs. 83.33% and 81.48%), the same as AUC (0.976 vs. 0.882 and 0.829), and there were statistical differences ( P<0.01); there were no significant differences in the specificity of each index alone and combination ( P>0.05). Conclusions:Compared with myeloma, the CT values at the energy levels of 40 to 80 keV by dual energy CT, serum PⅠNP and β-CTX levels in patients with spinal bone metastasis from lung cancer are increased, and the combination of the above indexes has ideal value in differential diagnosis of the two diseases.

A phantom study on the feasibility of recoverable fiducial marker implantation guided using the intelligent navigation bronchoscopy technology in Cyberknife Synchrony-based respiratory tracking / 中华放射医学与防护杂志

Objective:To explore the feasibility of recoverable fiducial marker implantation guided using the intelligent navigation bronchoscopy technology in the Cyberknife Synchrony-based respiratory tracking.Methods:CT scans of an inflatable pig lung after anti-rot processing were obtained. Then, eight simulated tumor lesion sites were designed in the left and right lung lobes using intelligent navigation software, with four classified as the sputum bronchial environment group and four classified as the wet bronchial environment group. Based on the implantation principle of Cyberknife fiducial markers, 32 recoverable fiducial markers were implanted around various simulated tumor lesions via bronchus under intelligent guidance. Then, the end-expiratory state of the pig lung was simulated, the pig lung was scanned again to obtain CT images of the implanted recoverable fiducial markers, and the number of successfully implanted fiducial markers was recorded. Eight deliverable Synchrony treatment protocols were designed using the Cyberknife planning system (Multiplan v4.6), and then the pig lung with simulated respiratory movements was exposed to radiation. After radiation, the implanted recoverable fiducial markers were retrieved using the bronchoscopy technique, and the number of successfully retrieved fiducial markers was recorded. Moreover, the translational errors, rotational errors, and rigid body errors were extracted from the Cyberknife log file and analyzed.Results:No recoverable fiducial markers slipped or fell during the experiment. Thirty-two recoverable fiducial markers were successfully implanted and recovered under the guidance of intelligent navigation bronchoscopy, with implantation and recovery success rates of both 100%. Moreover, the tracking rate and rigid body errors of the fiducial markers were 100% and less than 5 mm, respectively. The data from the Cyberknife log file indicated that there was no significant difference between the sputum bronchial environment group and the wet bronchial environment group in the translational errors in the left-right direction, the rotational errors in the roll direction, and the rotational errors in the pitch direction ( P>0.05). Compared to the wet bronchial environment group, the sputum bronchial environment group had slightly higher translational errors in front-back ( Z=-3.57, P<0.01) and cranio-caudal ( Z=-2.53, P<0.05) directions, lower rotational errors along the yaw axis ( Z = -3.88, P < 0.01), and lower rigid body error ( Z=-3.32, P<0.01), and the differences were all statistically significant. Conclusions:The recoverable fiducial marker implantation guided using the intelligent navigation bronchoscopy technology is feasible. Recoverable fiducial markers are stable in the bronchus of the phantom, and the Cyberknife tracking precision can meet clinical requirements. Therefore, the recoverable fiducial marker implantation guided using the intelligent navigation bronchoscopy technology has promising prospects in clinical and teaching applications.

Anti-tumor Effect of Ligustrazine Alone and in Combination with Western Medicine： A Review / 中国实验方剂学杂志

With serious environmental problems and the aging of population， the incidence of cancers worldwide has increased dramatically. For modern medicine， cancer is an incurable malignant disease with a high metastasis rate and strong cell proliferation and invasion ability. At present， clinical anti-cancer therapies mainly include chemotherapy and radiotherapy， but most chemotherapy drugs can cause serious side effects. Therefore， Chinese medicine with high safety has been widely used in anti-cancer treatment， which can inhibit the proliferation of cancer cells， improve the quality of life， and prolong life. Ligustrazine is a pyrazine alkaloid isolated and purified from Chuanxiong Rhizoma， which has pharmacological effects， such as anti-fibrosis， anti-oxidation， and anti-tumor. In recent years， ligustrazine， as an index active component of Chuanxiong Rhizoma alkaloids， has gradually become one of the hot spots in clinical medical research due to its pharmacological actions， and its anti-tumor effect has attracted more attention from researchers. The present study mainly investigated the anti-cancer effect of ligustrazine from the induction of tumor cell apoptosis and autophagy， inhibition of cell proliferation and migration， reversal of multidrug resistance of cancer cells， and inhibition of angiogenesis， and the anti-tumor efficacy was observed in various malignancies such as gastric cancer， lung cancer， rectal cancer， bladder cancer， breast cancer， and ovarian cancer. In addition， ligustrazine can be combined with cisplatin， paclitaxel， podophyllotoxin， chalcone， curcumin， and other drugs to exert an anti-tumor effect. This study conducted a literature review based on the anti-tumor mechanism of ligustrazine to provide a reference for the treatment of clinical malignancies.

The expression level of circular RNA_0005414 in Uygur type 2 diabetic group was higher than that in Uygur control group ( P<0.01), the expression level of circular RNA_0005414 in Han type 2 diabetic group was higher than that in Han control group ( P<0.01), the expression level of circular RNA_0005414 in Uygur type 2 diabetes group was higher than that in Han type 2 diabetes group, but the difference was not statistically significant ( P>0.05). In the Uyghur and Han groups, Spearman correlation analysis showed that the expression level of circular RNA_0005414 was positively correlated with fasting blood glucose, 2 h plasma glucose after glucose loading, HbA 1C, total cholesterol, fasting insulin, HOMA-IR ( P<0.05) and negatively correlated with HOMA-β ( P<0.01). Partial correlation analysis showed that circular RNA_0005414 expression level was positively correlated with fasting blood glucose, HbA 1C, and HOMA-IR ( P<0.01). Multivariate linear regression analysis showed that circular RNA_0005414 was the only factor affecting HOMA-β in Uygur patients with type 2 diabetes. Conclusion:The expression level of circular RNA_0005414 was closely related to islet cell function in Uygur type 2 diabetes patients, the up-regulation of circular RNA_0005414 may be involved in the occurrence and development of type 2 diabetes in Uygur.

Correlation between serum C1q/tumor necrosis factor-associated protein 3, soluble growth stimulation expression gene 2 protein, Elabela levels and prognosis in patients with acute ST-segment elevation myocardial infarction after percutaneous coronary intervention / 中国医师进修杂志

Objective:To investigate the correlation between serum C1q/tumor necrosis factor-associated protein 3 (CTRP3), soluble growth stimulation expression gene 2 protein (sST2), Elabela and prognosis in patients with acute ST-segment elevation myocardial infarction (ASTEMI) after percutaneous coronary intervention (PCI).Methods:The clinical data of 118 ASTEMI patients underwent PCI from March 2019 to March 2021 in Beijing Luhe Hospital, Capital Medical University were retrospectively analyzed. According to whether major adverse cardiovascular events (MACE) occurred within 90 d, the patients were divided into MACE group (36 cases) and non-MACE group (82 cases). The levels of CTRP3, sST2 and Elabela were detected by enzyme linked immunosorbent assay, and the patients were divided into high CTRP3 group and low CTRP3 group, high sST2 group and low sST2 group, high Elabela group and low Elabela group according to the median, there were 89 cases in each group. MACE was the end point event. Kaplan-Meier survival curve was drawn, and compared by log-rank test. Multivariate Cox regression was used to analyze the influencing factors of MACE after PCI in patients with ASTEMI. Receiver operating characteristic (ROC) curve was drawn to analyze the prediction efficiency of MACE.Results:The sST2 in MACE group was significantly higher than that in non-MACE group: (49.56 ± 17.67) μg/L vs. (30.76 ± 12.83) μg/L, the CTRP3 and Elabela were significantly lower than those in non-MACE group: (0.82 ± 0.42) μg/L vs. (2.02 ± 0.58) μg/L and (17.66 ± 3.85) μg/L vs. (21.84 ± 3.18) μg/L, and there were statistical differences ( P<0.01). The incidence of MACE in low CTRP3 group was significantly higher than that in high CTRP3 group: 49.15% (29/59) vs. 11.86% (7/59), the incidence of MACE in lowe Elabela group was significantly higher than that in high Elabela group: 42.37% (25/59) vs. 18.64% (11/59), and there were statistical differences ( χ2 = 19.35 and 7.84, P<0.01); the incidence of MACE in high sST2 group was significantly higher than that in low sST2 group: 38.98% (23/59) vs. 22.03% (13/59), and there was statistical difference ( χ2 = 4.00, P<0.05). The time from admission to MACE was defined as the survival time. Kaplan-Meier survival curve analysis result showed that the survival time in high CTRP3 group was significantly longer than that in low CTRP3 group: (81.02 ± 3.23) d vs. (56.31 ± 4.74) d, the survival time in low sST2 group was significantly longer than that in high sST2 group: (74.52 ± 3.87) d vs. (61.12 ± 5.07) d, the survival time in high Elabela group was significantly longer than that in low Elabela group: (77.95 ± 3.48) d vs. (58.64 ± 4.89) d, and there were statistical differences ( P<0.05). Multivariate Cox regression analysis result showed that the LVEF, TnI, CTRP3, sST2 and Elabela were independent influencing factors of MACE after PCI in patients with ASTEMI ( HR = 1.632, 1.124, 0.712, 1.482 and 0.676; 95% CI 1.531 to 3.271, 1.012 to 1.482, 0.547 to 0.842, 1.063 to 1.852 and 0.536 to 0.725; P<0.01). ROC curve analysis result showed that the cut-off values of CTRP3, sST2 and Elabela in prediction MACE after PCI in patients with ASTEMI were 0.79, 52.17 and 16.82 μg/L respectively, areas under curve were 0.833, 0.732 and 0.739 respectively. Conclusions:CTRP3, sST2 and Elabela can be used as indicators to predict the early prognosis of ASTEMI patients after PCI.

Recent advance in intraspinal pressure monitoring in traumatic spinal cord injury / 中华神经医学杂志

Traumatic spinal cord injury (TSCI) is a common nerve injury in the world, which has a high incidence and disability rate. Intraspinal pressure (ISP) monitoring is performed by placing a pressure sensing probe under the dura of the most severe part of the spinal cord injury after anterior/posterior laminectomy or vertebral body decompression. ISP value is monitored dynamically and objectively in real time by the pressure sensing system. Recent studies have found that ISP monitoring plays an important role in the clinical management and prognosis evaluation of TSCI. The author reviews the recent advance in ISP monitoring in TSCI in order to provide references for the improvement of clinical diagnosis and treatment of TSCI.
