Nuclear radiation exposure events and tumor radiotherapy are highly susceptible to a range of psychological, physiological and other health problems, which can seriously affect patients' quality of life. It has been shown that 87.5 % of tumor patients are exposed to varying degrees of radiation injury during radiotherapy. The treatment of radiation injury (RI) in modern medicine is limited to drug therapy, cell therapy, etc. Among them, the most chemical drugs cause many adverse reactions including fatigue, nausea, vomiting, etc., and there are very few drugs dedicated to the treatment of RI. Traditional Chinese medicine (TCM) is a rich natural medicinal resource, which has a wide range of pharmacological activities, multiple targets of action and minimal toxic side effects. Many studies have demonstrated that TCM and its compound preparations have enormous potential in the treatment of radiation induced comprehensive diseases. However, TCM is limited in clinical application due to its slow onset of action, complex active ingredients, and low bioavailability. Therefore, the article reviews the application, molecular mechanisms, and new dosage forms of TCM in the prevention and treatment of RI. On this basis, we will focus on discussing the development advantages and application prospects of the combination of traditional Chinese and Western medicine to achieve highly efficient treatment of RI. This review aims to provide scientific and effective drug delivery strategies and basic theoretical support for the clinical effective treatment of RI with TCM, and further promote the innovative development of TCM.

AIM:This study aims to investigate the molecular mechanism by which tubeimoside I(TBMS1)inhibits Snail expression in pancreatic cancer cells(PANC-1).METHODS:Human pancreatic cancer PANC-1 cells were cultured in vitro.The inhibitory effect of TBMS1 on PANC-1 cells was assessed using the MTT assay,and the data were analyzed based on the IC50 value of TBMS1.The impact of TBMS1 on the clonal formation ability of PANC-1 cells was evaluated through colony formation assays.The Transwell assay was employed to assess the effect of TBMS1 on the migrato-ry capability of PANC-1 cells.Apoptosis and cell cycle alterations in PANC-1 cells were analyzed using acridine orange staining and flow cytometry.The expression of Snail protein in pancreatic cancer and its relationship with survival of the patients were analyzed using the GEPIA database and Kaplan-Meier Plotter data.Immunofluorescence staining was con-ducted to investigate the effect of TBMS1 on Snail expression,while Western blot was used to evaluate the expression of poly(ADP-ribose)polymerase(PARP),E-cadherin and Snail in the cells.The ubiquitination of Snail protein was mea-sured using immunoprecipitation techniques.RESULTS:As the concentration of TBMS1 increased,the survival rate and number of clones formed by PANC-1 cells progressively decreased,leading to apoptosis,cleavage of PARP,and cell cycle arrest in the G1 phase.There was also a reduction in the proportion of cells in the S phase and a decrease in cell migration ability.The expression of Snail protein,a critical factor in cell migration,was inhibited,while E-cadherin protein levels were increased.Treatment with the proteasome inhibitor MG132 was able to reverse the suppression of Snail protein ex-pression caused by TBMS1.Immunoprecipitation results indicated that TBMS1 enhances the ubiquitination and subse-quent degradation of Snail protein.CONCLUSION:TBMS1 effectively inhibits the malignant progression of pancreatic cancer cells by promoting the ubiquitination and degradation of Snail protein in PANC-1 cells.

Objective:To assess the left ventricular (LV) myocardial mechanical dysfunction in patients with cirrhosis using ultrasonic layer-specific strain imaging and to explore its value in clinical application.Methods:A total of 80 consecutive cirrhosis patients without cardiovascular diseases were prospectively enrolled from October 2020 to March 2021 in Sichuan Provincial People′s Hospital, 39 of whom were assigned to the compensated group and 41 were assigned to the decompensated group according to the occurrence of portal hypertension. Forty-three healthy volunteers during the same period were randomly recruited as the control group. Transthoracic echocardiography was performed to assess the LV configuration and functional parameters. LV global longitudinal strain in endocardial, middle and epicardial myocardium (GLSendo, GLSmid, GLSepi), and longitudinal strain (LS) in basal, middle and apical segments, and peak strain dispersion (PSD) were obtained using ultrasonic layer-specific strain imaging. ΔLS was calculated by the formula of GLSendo-GLSepi. Then, the differences of related parameters among three groups were compared.Results:①Conventional echocardiography: compared with the control group, the interventricular septum end-diastolic thickness (IVSTd), left ventricular posterior wall end-diastolic thickness (LVPWd), left ventricular mass (LVM) and LVM index (LVMI) were increased in compensated and decompensated groups (all P<0.05), while no significant differences in conventional echocardiographic parameters were identified between the two cirrhosis groups (all P>0.05). ②Global layer-specific strain: compared with the control group, GLSendo, GLSmid, GLSepi and ΔLS were decreased and PSD was increased in compensated and decompensated groups (all P<0.05); Moreover, the decompensated group showed a more impaired GLSendo, GLSmid and GLSepi than compensated group (all P<0.05), whereas there were no significant differences of ΔLS and PSD between the two groups(all P>0.05). ③Segmental layer-specific strain: compared with the control group, LS values of three layers in compensated and decompensated groups were reduced at basal, middle and apical levels (all P<0.05); Compared with the compensated group, LS values of three layers in decompensated group tended to be reduced at above there levels, but only apical segments had significant differences (all P<0.05). Conclusions:There are different degrees of LV mechanical dysfunction in patients with variable severity of cirrhosis. Ultrasonic layer-specific strain imaging has the potential to quantitatively assess the state of cardiac involvement in patients with cirrhosis and to provide visual evidence for the early and accurate diagnosis of myocardial injuries.

Objective:To discuss the curative effect between direct decompression and indirect decompression plus lumbo-iliac fixation for treatment of Denis type II sacrum fracture combined with sacral foraminal bone space-occupying lesion and sacral nerve injury.Methods:A retrospective case-control study was performed on clinical data of 47 patients with Denis type II sacrum fracture combined with sacral foraminal bone space-occupying lesion and sacral nerve injury admitted to Honghui Hospital Affiliated to Xi'an Jiaotong University School of Medicine from March 2012 to March 2017. All patients underwent lumbo-iliac internal fixation. The operation time ranged from 3 to 14 days after injury, with an average of 6 days. In direct decompression group ( n=26), the sacral foramina mass was removed during the operation and direct decompression was performed. There were 16 males and 10 females, with age of (36.2±8.4)years. In indirect decompression group ( n=21), indirect decompression through traction and distraction was performed. There were 11 males and 10 females, with the age of (38.7±9.8)years. Operation time, intraoperative blood loss, bone union, Mears imaging evaluation, Gibbons score, and Majeed function score were compared between the two groups. Postoperative complications were observed as well. Results:All patients were followed up for 1233 months, with an average of 16.7 months. The operation time and intraoperative blood loss in direct decompression group were (112.3±26.3)minutes and (512.1±29.4)ml, which had no significant differences in comparison with that in indirect decompression group [(129.3±25.1)minutes and (529.7±22.1)ml] ( P>0.05). Bone union was observed in all patients. According to the Mears imaging evaluation, the direct decompression group had anatomical reduction in 17 patients, and satisfactory reduction in 9, and the indirect decompression group had anatomical reduction in 15 patients and satisfactory reduction in 6 ( P>0.05). At the last follow-up, Gibbons score in direct decompression group was lower than that in the indirect decompression group [(1.2±0.3)points vs. (2.2±0.5)points] ( P<0.01); Majeed function score in direct decompression group was higher than that in indirect decompression group [(87.3±11.4)points vs. (68.5±16.7)points] ( P<0.01). In direct decompression group, 1 patient had deep wound infection, while in indirect decompression group, 1 patient had pressure sore due to the protrusion of the tail of the iliac screws on the skin. Conclusion:For Denis type II sacrum fracture combined with sacral foraminal bone space-occupying lesion and sacral nerve injury, direct decompression with lumbo-iliac fixation can obtain better neural functional recovery and functional recovery of life compared with the indirect decompression.

Vertebral body augmentation for spine-related diseases has the advantages of minimally invasive surgery,obvious postoperative pain relief,and quick postoperative recovery compared with open surgery.It can quickly reconstruct spinal stability,relieve pain,and improve patients' quality of life.Intraoperative injection of bone cement into the diseased vertebral body carries the risk of bone cement leakage during the process.Knowing well the complications is helpful to the timely clinical treatment so as to avoid delays,and understanding the risk factors can facilitate targeted measures to prevent leakage during surgery.Therefore,to understand the consequences of bone cement leakage,leakage incidence rate,related risks factors and preventative measures is conducive to clinical treatment and surgery safety.The authors discuss the complications and risk factors related to bone cement leakage after vertebral body augmentation,in order to deepen the understanding of bone cement leakage,provide reference for clinical work,and improve the safety of surgery.

Objective To analyze the process of clinical nursing operation assessment in a third-grade class-A hospital in China, and design the scoring system of clinical nursing operation examination (SSCNOE), and discuss its clinical application effect. Methods Through operation process analysis chart to analyze the flow of current clinical nursing operation assessment of shanxi provincial people's hospital to look for improvement priorities that can be optimized, and based on Microsoft Visual Basic technology and 15 commonly used clinical nursing operation, we developed SSCNOE. A total of 102 nurses were selected as subjects and were randomly divided into the experimental and control groups using random numbers. The experimental group accepted SSCNOE examination, while the control group received the traditional paper test. The differences in the examination time and examination cost between the two groups were compared. Results SSCNOE simplified the examination process of clinical nursing operation and saved a lot of manpower, material and financial resources. The time required to use SSCNOE was (202.13±24.69)min, shorter than the traditional assessment (347.67±6.51)min (t=12.99, P<0.01), and the overall cost was (948.13± 72.47)yuan, lower than the traditional test (1689.12 ± 126.72)yuan (t=13.56, P<0.01). Conclusion The research and application of SSCNOE can improve the efficiency of the assessment of nursing operation, save the cost of examination and improve the level of hospital nursing information construction.

Objective To investigate the correlation factors for surgical outcome of sacral decompression and lumbopelvic fixation in H-shaped sacral fracture and the methods to prevent and treat the complications.Methods From January 2008 to January 2016,45 patients with H-shaped sacral fracture treated by sacral decompression and lumbopelvic fixation were respectively analyzed,including 29 men and 16 women,mean age 41.2 (range,24-53 years),mean follow-up time 52.6 months (range,16-93 months).The surgical outcome was evaluated by pelvic outcome score,and correlation factors were analyzed.We analyzed whether each factor was in correlation with pelvic outcome score.Then we integrated the statistically significant indicators into Logistic regression equation to determine the related factors.Postoperative complications were all recorded.Results The average operation time was 161.2 min (range,100-220 min),average blood loss was 491.6 ml (range,370-1 000 ml),injury-surgery interval was 7.2 d (range,1-23 d).In terms of pelvic outcome score,31 (68.9％) patients had satisfactory result and 14 (31.3％) patients had unsatisfactory result.Univariate x2 analysis suggested that cauda equina injury,Roy-Camille classification,L5S1 facet injury,fracture line,kyphotic angle,injury-surgery interval,decompression approach and inserting sacral screws were correlated with pelvic outcome score,but gender,age,injury mechanism and L5 pedicle fracture had no relation with pelvic outcome score.The multivariate Logistic regression analysis showed that cauda equina injury,Roy-Camille classification,fracture line,kyphotic angle,injury-surgery interval,decompression approach and inserting sacral screws were closely related to pelvic outcome score,but L5S1 facet injury was excluded.2 patients required early surgical procedures with proper antibiotics for deep wound infection;3 patients complained pain related to hardware prominence and the pain subsided after removal of implants;1 patient got unilateral rod breakage at 3-6 months and achieved bony fusion after nine months of observation.Conclusion Sacral decompression and lumbopelvic fixation is effective in neurological recovery and early ambulation in treating H-shaped sacral fracture.Better surgical outcome is related to timely surgery,preoperative or intraoperative bone traction,sacral screws insertion,incomplete cauda equina injury,Roy-Camille type Ⅱ,fracture line penetrating S2 and kyphotic angle less than 40°.

Sacral fractures are usually caused by high-energy violence,often complicated with injury to the lumbosacral plexus.In severe cases,they may cause instability of the posterior pelvic ring or of the lumbosacral junction.Their classifications commonly used in clinic are Denis,Tile,Isler and refined Denis type Ⅲ ones proposed by Roy-Camille and Gibbons.Recently,classifications of the lumbosacral lesions and scoring systems of the injury severity have often been used clinically.At present,internal instrumentation of sacral fractures is developing along the direction of high efficiency,safety and minimal invasion,but different methods of internal fixation have their own indications which should be strictly followed.This review summarizes the classifications of sacral fractures and their treatment advances.
