Objective To provide alternative delivery methods of novel oral antitumor drugs for patients with dysphagia.Methods The retrieval range was determined according to the"Guidelines for Clinical Application of Novel Antitumor Drugs(2022 edition)".By consulting the instructions and searching databases such as PubMed,Micromedex,UpToDate,etc.,the preparation,stability,storage,and related clinical information of temporary liquid drug formulations were obtained.Results Seventy novel oral anticancer drugs were included in the literature search.Thirty-three drugs had relevant literature or data supporting alternative administration methods,only eight had information on alternative administration in the instructions,and the level of evidence for other drugs varied.Conclusion The evidence levels were low for most temporary liquid formulations,and medical teams should fully consider the advantages and disadvantages of using these products outside the instructions and use them with caution.

Objective:To evaluate the efficacy and safety of oral anisodine hydrobromide tablets in the treatment of nonarteritic anterior ischemic optic neuropathy (NAION).Methods:A multicenter nonrandomized controlled trial was conducted.A total of 282 acute NAION patients (282 eyes) were recruited from 16 hospitals in China from July 2020 to May 2021.Patients were divided into two groups according to treatment methods, which were control group (124 cases, 124 eyes) receiving regular treatment including citicoline sodium plus Ginkgo biloba leaf liquid extract or Ginkgo biloba leaf extract tablets plus mecobalamin, and experimental group (158 cases, 158 eyes) receiving treatment in control group plus oral anisodine hydrobromide tablets 1 mg, twice daily for 2 to 3 months.Best corrected visual acuity (BCVA), visual field index (VFI), peripapillary retinal nerve fiber layer (pRNFL) and radial peripapillary capillary vessel density (RPC) were assessed at 1, 2, 3, and 6 months after enrollment using the standard decimal visual acuity chart, 750i Humphery visual field analyzer, Cirrus HD-OCT 4000/Cirrus HD-OCT 5000, RTVue-XR optical coherence tomography respectively.The primary outcomes were BCVA and VFI, and the secondary outcomes were pRNFL, RPC, and the side effects during the follow-up.The study adhered to the Declaration of Helsinki.All patients were fully informed about the treatment and purpose of this study and voluntarily signed the informed consent form.The study protocol was approved by Chinese PLA General Hospital (No.S2020-021-01). Results:In all, 242 patients (242 eyes) completed the follow-up of BCVA, and 98 patients (98 eyes) completed the VFI follow-up.In terms of visual function, BCVA and VFI improved significantly over time in the two groups, and BCVA and VFI were better in experimental group than in control group at various follow-up time points (all at P<0.05). In terms of structure, pRNFL gradually decreased in both groups with the extension of treatment, and pRNFL was significanthy thinner in experimental group than in control group at various follow-up time points (all at P<0.05). There was no significant difference in RPC between the two groups at the last follow-up ( P>0.05). There were two cases with side effects and one case was discontinued due to side effects 25 days after enrollment. Conclusions:Oral anisodine hydrobromide can improve visual acuity and visual field in NAION and accelerate the regression of optic disc edema, with good safety.

Objective:To observe the clinical and imaging characteristics of radiation optic neuropathy (RION).Methods:A retrospective clinical study. A total of 43 patients (69 eyes) who were diagnosed with RION at the Chinese PLA General Hospital from 2010 to 2021 were included in this study. There were 23 males (36 eyes) and 20 females (33 eyes). The age of patients at the time of radiation therapy was 49.54±13.14 years. The main dose of radiotherapy for lesions was 59.83±14.12 Gy. Sixteen patients were treated with combined chemotherapeutic agents. The clinical details of best corrected visual acuity (BCVA) and color photography of the fundus were collected. Forty-six eyes underwent optical coherence tomography (OCT), visual field were examined in 30 eyes, magnetic resonance imaging (MRI) were performed in 40 eyes. The BCVA examination was performed using Snellen visual acuity chart, which was converted to minimum resolution angle logarithm (logMAR) visual acuity during recording. Hyperbaric oxygen therapy (HBOT) was performed in 10 patients (13 eyes), 9 patients (12 eyes) were treated with intravenous methylprednisolone (IVMP), 12 patients (23 eyes) were treated with HBOT combined with IVMP and control group of 12 patients (21 eyes) were only treated with basal treatment. And grouped accordingly. To observe the changes in onset, recovery, and final BCVA of the affected eye as well as thickness changes of the retinal nerve fiber layer (RNFL) of the optic disc and inner limiting membrane-retinal pigment epithelium (ILM-RPE) layer of the macular area, and final outcome of BCVA with different treatment modalities in affected eyes. The RNFL and ILM-RPE layer thicknesses were compared between patients with different disease duration as well as between treatment regimens using independent samples t-test. Results:Of the 43 cases, vision loss was monocular in 17 patients (39.53%, 17/43) and binocular in 26 patients (60.47%, 26/43). The latency from radiotherapy to onset of visual loss was 36.33±30.48 months. The duration of RION ranged from 1 week to 10 years, in which the disease duration of 37 eyes ≤2 months. Subacute visual acuity loss was present in 41 eyes. logMAR BCVA<1.0, 1.0-0.3, >0.3 were 45, 15, and 9 eyes, respectively. Optic disc pallor and optic disc edema were found in 10 (27.03%, 10/37), 3 (8.11%, 3/37) eyes, respectively, within 2 months. The superior RNFL [95% confidence interval ( CI) 2.08-66.56, P=0.038] and the outer circle of the inner limiting membrane to retinal pigment epithelium (ILM-RPE) (95% CI 4.37-45.39, P=0.021) layer thinned significantly during the first month. The center of the ILM-RPE layer thickened (95% CI-32.95--4.20, P=0.015) significantly during the first two months. The inner circle temporal quadrant of the ILM-RPE layer thickened (95% CI -42.22--3.83, P=0.022) significantly from the third to sixth month, and the RNFL except for the temporal quadrants and the average RNFL, inner circle superior quadrant and outer circle of the ILM-RPE layer thinned significantly after 6 months ( P<0.05). Among the 40 eyes that underwent MRI examination, 33 eyes (82.50%, 33/40) were affected by T1 enhancement of optic nerve, including 23 eyes (69.70%, 23/33) in intracranial segment; 12 eyes with thickening and long T2 signal (36.36%, 12/33). After treatment, BCVA was restored in 17 eyes (24.6%, 17/69) and final BCVA improved in 9 eyes (13.0%, 9/69). There was no significant difference between HBOT, IVMP and HBOT combined with IVMP therapy in improving BCVA recovery or final BCVA compared with the control group, respectively ( t=-1.04, 0.61, 1.31,-1.47, -0.42, 0.46; P>0.05). Conclusions:The structural damage of the RNFL and ILM-RPE layer occurred during the first month, the RNFL showed progressive thinning during the follow-up period, while the ILM-RPE layer showed thinning-thickening-thinning. MRI shows T1 enhancement of the optic chiasma and segments of the optic nerve, and the enhanced segments are usually accompanied by thickening and long T2. HBOT and IVMP have no obvious effect on RION.

BACKGROUND: Although previous studies have shown that meteorological factors such as temperature are related to the incidence of bacillary dysentery (BD), researches about the non-linear and interaction effect among meteorological variables remain limited. The objective of this study was to analyze the effects of temperature and other meteorological variables on BD in Beijing-Tianjin-Hebei region, which is a high-risk area for BD distribution. METHODS: Our study was based on the daily-scale data of BD cases and meteorological variables from 2014 to 2019, using generalized additive model (GAM) to explore the relationship between meteorological variables and BD cases and distributed lag non-linear model (DLNM) to analyze the lag and cumulative effects. The interaction effects and stratified analysis were developed by the GAM. RESULTS: A total of 147,001 cases were reported from 2014 to 2019. The relationship between temperature and BD was approximately liner above 0 °C, but the turning point of total temperature effect was 10 °C. Results of DLNM indicated that the effect of high temperature was significant on lag 5d and lag 6d, and the lag effect showed that each 5 °C rise caused a 3% [Relative risk (RR) = 1.03, 95% Confidence interval (CI): 1.02-1.05] increase in BD cases. The cumulative BD cases delayed by 7 days increased by 31% for each 5 °C rise in temperature above 10 °C (RR = 1.31, 95% CI: 1.30-1.33). The interaction effects and stratified analysis manifested that the incidence of BD was highest in hot and humid climates. CONCLUSIONS This study suggests that temperature can significantly affect the incidence of BD, and its effect can be enhanced by humidity and precipitation, which means that the hot and humid environment positively increases the incidence of BD.

Objective:To evaluate the occurrence of nocturnal hypotension (NHP) in nonarteritic anterior ischemic optic neuropathy (NAION).Methods:A evidence-based medicine study. Chinese and English as search terms for NAION and NHP was used to search literature in PubMed of National Library of Medicine, Embase, Web of science, Cochrane Library, Clinical Trials, Wanfang, and China National Knowledge Infrastructure and China Biology Medicine disc. Incomplete or irrelevant literature and review literature were excluded. The literature was meta-analyzed using Review Manager 5.4 and STATA 15.0. The 95% confidence interval ( CI) were selected as the estimated value of effect size, the occurrence of NHP in NAION was calculated, and sensitivity analysis and publication bias analysis were also performed to assess the robustness of pooled outcomes. Results:According to the search strategy, 159 articles were initially retrieved, and 8 articles were finally included for meta-analysis, three prospective studies and five retrospective studies. The occurrence of NHP in NAION was 43% (95% CI, 0.36-0.50). Sensitivity analyses confirmed that the evidence was robust. Subgroup analyses showed that the occurrence of NHP in NAION nearly the same in White patients (47%, 95% CI 0.39-0.55) and Chinese patients (41%, 95% CI 0.32-0.51). The occurrence of NHP in NAION was higher in using night mean artery pressure (45%, 95% CI 0.31-0.60) as the diagnostic criteria than using night systolic blood pressure & night diastolic blood pressure (40%, 95% CI 0.32-0.50). Conclusions:The occurrence of NHP in NAION was 43%; the occurrence was similar in patients of different ethnicities. The diagnosis rate could be improved by using nMAP < 70 mm Hg (1 mm Hg=0.133 kPa) as a diagnostic criterion for NHP. Careful intervention should be taken for the blood pressure of patients with NAION and NHP.

Objective: To investigate the effects of scleral crosslinking using genipin on ocular biological parameters and scleral biomechanics of form-deprivation myopia rabbits. Methods: Sixty healthy New Zealand rabbits of 14 days old were collected.The right eyes were selected as experimental eye.The rabbits were randomly divided into three groups: control group with no treatment; myopia model group with eyelid suture procedure performed on the right eye; genipin injection group with eyelid suture procedure performed on the right eye combined with subconjunctival injection of genipin.The suture was removed 60 days after the eyelid suture procedure.The diopter, length of vitreous cavity, and axial length were measured.The sclera at 1: 00 and 7: 00 position of the experimental eye was used to make a scleral strip.The thickness, elastic modulus, creep rate, ultimate stress and ultimate strain of the sclera were measured.This study was approved by the animal experimental Ethics Committee of Bethune International Peace Hospital (2018-ky-09). Results: The diopters of genipin injection group, myopia model group and control group were (2.50±1.38), (0.33±0.52) and (2.08±0.52)D, respectively, the axial lengths of the three groups were (15.33±0.82), (15.83±0.41) and (15.00±0.43)mm, respectively; the changes in vitreous cavity lengths were (1.50±0.79), (2.59±0.83) and (1.48±0.66)mm, respectively; and the ratios of vitreous cavity length to axial length were 0.46±0.02, 0.51±0.02 and 0.47±0.02, respectively.The diopter in myopia model group was significantly lower than those in control group and genipin injection group, the axial length in myopia model group was significantly longer than that in control group, the change in vitreous cavity lengths and ratio of vitreous cavity length to axial length in myopia model group were significantly higher than those in control group and genipin injection group, the axial length in myopia model group was significantly longer than that in control group, the differences were statistically significant (all at P<0.05). The elasticity modulus was (9.10±3.12)MPa and ultimate stress was (1.42±0.57)MPa in genipin injection group, which were significantly higher than (6.98±3.30)MPa and (1.15±0.57)MPa in control group, and (6.25±3.17)MPa and (0.82±0.38)MPa in myopia model group (all at P<0.05). The ultimate strain was (20.99±5.60)% in genipin injection group, which was significantly lower than (25.08±6.35)% in control group and (27.78±8.20)% in myopia model group, with significant differences between them (both at P<0.05). Conclusions Posterior sub-Tenon capsule injection of genipin for collagen crosslinking in the sclera increases the biomechanical strength of sclera and effectively prevents the development of form-deprivation myopia in rabbits, which provides a new idea for the prevention and treatment of myopia in the future.

[Abstract] MicroRNA (miRNA) is non-coding RNA molecule consisting of 20-25 nucleotides. It plays an important role in regulation of tumorigenesis and progression, including proliferation, differentiation and apoptosis of cancer cells, which directly affect the progress of tumors. Peripheral blood miRNA is relatively more stable, and easier to acquired and detected than tissue miRNA. It is a new generation biomarker for early detection and early diagnosis of tumors. It is also one of the main development directions of research and application in precision medicine. Methods commonly used in peripheral blood miRNA detection are RT-PCR, electrochemical detection, NanoString Technologies, genechip and high-throughput sequencing etc. Multiple miRNAs in peripheral blood are the early diagnostic markers for non-small cell lung cancer, esophageal squamous cell carcinoma, pancreatic cancer, squamous cell carcinoma of the head and neck, ovarian cancer, colorectal cancer, breast cancer, prostate cancer and hematological malignancies. Combined detection of multiple peripheral blood miRNAs, as well as combined detection of tumor-specific miRNAand serological, imaging and other auxiliary methods, can improve the sensitivity and specificity of tumor diagnosis at early stage.

Aquaporin1 (AQP1) is a member of a family of specific channel proteins which could mediate the trans-biofilm transportation of small molecules such as water.Recent studies have shown that AQP1 is highly expressed in cancer tissues.It also has an effect on the proliferation and migration of cancer cells, angiogenesis in cancer and so on.AQP1 is expected to be a marker of screening, diagnosis, treatment and prognosis at tumor early stage.

Objective To assess the optimal visiualization capacity of brachial plexus with three-dimensional nerve-sheath signal increased with inked rest-tissue rapid acquisition of relaxation imaging (3D SHINKEI), exploring the feasibility of preliminary diagnostic value on brachial plexus diseases. Methods MRI scans were performed on 24 healthy volunteers with no history of brachial plexus injury, and 46 patients whose outcomes of lesions had been verified as post-ganglionic brachial plexus injuries by surgery or clinical follows-up . The scan series consist 3D SHINKEI, STIR in the coronal plane as well as DW-MRN in the axial plane using a 3.0 T MR system. The source and post-processed images of 3D SHINKEI and DW-MRN were scored according to the optimal visibility on brachial plexus, in the meanwhile, contrast-to-noise ratio of the original images in the 3D SHINKEI and STIR sequences were calculated separately. Two radiologists blindly compared the detection rate of positive brachial plexus injuries between 3D SHINKEI and STIR in 46 patients. And then analyze the outcomes by means of Kappa test, Mann-Whitney test , independent sample t test, and Chi-square test. Results Post-ganglionic brachial plexus showed high intensity in the 3D SHINKEI sequence. In the 24 healthy volunteers, the scores by the two radiologists were 3.6 ± 0.6, 3.5 ± 0.6, 3.0 ± 0.2, 2.9 ± 0.1, respectively. There was statistical difference between the two sequences (Z=2.667,P=0.008,P<0.05). And the Kappa was 0.8 and 0.6 with favorable consistency. The CNR of 3D SHINKEI and STIR were 0.61 ± 0.07, 0.42 ± 0.03 (t=12.78, P=0.001, P<0.05). The positive detection rates of post-ganglionic brachial plexus injuries on 3D SKINKEI and STIR were, 78.3%, 52.2%(χ2=9.421, P<0.05). Conclusions 3D SHINKEI sequence demonstrates robust visibility consistently and can clearly display the structures and signals of post-ganglionic abnormality, compared with DW-MRN and STIR. This technique can be helpful to provide more complementary information to further confirm the diagnosis of brachial plexus injuries.

Interferon alpha-inducible protein 27 (IFI27) is a newly discovered protein that participates in biological functions such as apoptosis,cell autophagy,oncolytic and immunoregulation.It also plays a major role in promoting tumor development,such as in breast cancer,ovarian cancer,liver cancer,squamous cell carcinoma and so on.Besides,studies have shown that IFI27 can interact with signal transducer and activator of transcription 1,microRNAs,interferon regulatory factor 4 and other genes,which promotes the development of tumors.Therefore,IFI27 is expected to be a marker for the occurrence and development of tumors,providing a new target for cancer therapy.
