ABSTRACT

OBJECTIVE@#To explore the genetic etiology for a Chinese pedigree affected with Lesch-Nyhan syndrome.@*METHODS@#Members of the pedigree who had visited the Genetic Counseling Clinic of Linyi People's Hospital on February 10, 2022 were selected as the study subjects. Clinical data and family history of the proband were collected, and trio-whole exome sequencing (trio-WES) was carried out for the proband and his parents. Candidate variants were verified by Sanger sequencing.@*RESULTS@#Trio-WES revealed that both the proband and his cousin brother had harbored a hemizygous c.385-1G>C variant in intron 4 of the HPRT1 gene, which was unreported previously. A heterozygous c.385-1G>C variant of the HPRT1 gene was also found in the proband's mother, grandmother, two aunts, and a female cousin, whilst all phenotypically normal males in his pedigree were found to have a wild type for the locus, which has conformed to an X-linked recessive inheritance.@*CONCLUSION@#The heterozygous c.385-1G>C variant of the HPRT1 gene probably underlay the Lesch-Nyhan syndrome in this pedigree.

ABSTRACT

Objective:To explore the risk factors of acute kidney injury(stage 3)developed within 48 hours in elderly patients with sepsis, and to use them to develop a risk prediction model and then evaluate and externally validate the model.Methods:Clinical data of all elderly patients(age≥ 60 years)with sepsis in the intensive care medicine information database(MIMIC-Ⅳ v1.0)were extracted.Independent risk factors were determined by multivariate logistic regression analysis.A risk prediction model was constructed, a nomogram was drawn, and the receiver operating characteristic curve(ROC)and the Hosmer-Lemeshow(H-L)test were used to evaluate the model's prediction accuracy and R-squared.Clinical data of elderly patients(age≥ 60 years)with sepsis admitted to the Department of Critical Care Medicine of the Second People's Hospital of Hefei from May 2019 to October 2021 were retrospectively collected and fed into the prediction model to conduct external validation.Results:A total of 1 977 elderly patients with sepsis were screened out from the MIMIC-IV database and included in the training set, of whom, 544 developed AKI-stage 3 within 48 hours.Univariate analysis was performed for factors that might be associated with acute kidney injury in elderly patients with sepsis.Compared with the normal group that did not progress to AKI stage 3, there were statistically significant differences in 28 indicators, such as the duration of ICU stay, intravenous fluid intake in 24 hours, and use of vasoactive drugs[5(3, 9)d vs.7(4, 12)d; 2.05(1.17, 3.27)ml·kg -1·h -1vs.2.37(1.47, 4.10)ml·kg -1·h -1; 761(53.11%) vs.375(68.93%), P<0.001]. Based on the results of multivariate logistic regression analysis, a prediction model was finally constructed with 9 variables: albumin( OR=0.983, 95% CI: 0.966-0.999, P=0.040), aspartate transaminase( OR=1.000, 95% CI: 1.000-1.000, P<0.001), APTT( OR=1.005, 95% CI: 1.001-1.009, P=0.028), total bilirubin( OR=1.003, 95% CI: 1.001-1.004, P=0.001), serum creatinine( OR=1.005, 95% CI: 1.004~1.007, P<0.001), Charlson score( OR=1.117, 95% CI: 1.061-1.177, P<0.001), intravenous fluid intake in 24 hours( OR=1.101, 95% CI: 1.034-1.173, P=0.003), weight( OR=1.023, 95% CI: 1.018-1.029, P<0.001), and mechanical ventilation( OR=2.412, 95% CI: 1.843-3.157, P<0.001). Then a nomogram was generated.The area under the ROC curve(AUC)of the prediction model was 0.755(95% CI: 0.731-0.780), and the H-L test was conducted( χ2=10.89, P=0.208>0.05), indicating a good fit.Data from 102 elderly patients were included in the validation set, with 27 cases that had developed AKI-stage3 within 48 hours, and were fed into the prediction model, with an AUC of 0.778(95% CI: 0.676-0.880)and χ2=3.72 and P=0.882>0.05 from the H-L test, consistent with the results of the training set. Conclusions:The model has some predictive value for acute kidney injury in elderly patients with sepsis.

ABSTRACT

Radiotherapy (RT) is the primary local treatment modality for brain metastases, which are common secondary malignancies. Image-guidance system such as cone beam computed tomography (CBCT) may be not applicable to adaptive radiotherapy (ART), as well as hypofractionated RT in brain metastases, because it cannot clearly show the shrinkage and deformation of intracranial tumors, and the peritumoral edema changes in a real-time manner. Magnetic resonance (MR) image has high spatial resolution and soft tissue contrast and no radiation dose burden compared with CBCT. MR-guided adaptive radiotherapy (MR-gART) allows real-time tracking of deformation and position changes of the intracranial tumors, and enables online planning reconstruction during the treatment process. MR-gART could deliver high dose irradiation to the tumors while reducing the radiation dose of important organs at risk around, which contributes to achieving precision RT. In this work, the application of MR-gART in brain metastases was reviewed.

ABSTRACT

Objective:To explore the clinical efficacy of reconstructing the calcaneocuboid and calcaneonavicular ligaments with the autologous semitendinosus for chronic bifurcate ligament injury.Methods:A retrospective study was conducted to analyze the clinical data of 12 patients with chronic bifurcate ligament injury who had been treated by anatomical reconstruction with the autologous semitendinosus from March 2018 to January 2021 at Department of Foot and Ankle Surgery, The Fourth Hospital of Wuhan. There were 4 males and 8 females with an age of (41.4±9.6) years. Seven left and 5 right feet were affected; the time from injury to surgery was (9.3±4.3) months. The surgical efficacy was evaluated based on anteroposterior and lateral imaging assessments of foot weight-bearing at 6 months postoperation, comparison of the visual analogue scale (VAS) pain scores for foot weight-bearing walking and the American Orthopaedic Foot and Ankle Society (AOFAS) midfoot scores between preoperation and the last follow-up, stress test for stability of the transverse tarsal joint, recovery of movement, and occurrence of complications.Results:All patients were followed up for (18.4±4.0) months. Their sports activities were completely resumed after postoperative (6.8±3.9) months. Primary wound healing was achieved in all patients. One patient suffered from cutaneous nerve lesion and skin numbness, the symptoms of which disappeared after conservative treatment. Double harmonic curves were observed on the anteroposterior and lateral imaging films of foot weight-bearing in all patients. The spaces in the calcaneocuboid and the calcaneonavicular joints were normal, the articular positions were matched, and the calcaneocuboid joint was stable without recurrence or worsening of displacement. The VAS decreased significantly from preoperative 6.5 (5.6, 7.0) to 0.0 (0.0, 1.0) at the last follow-up, and the AOFAS mid-foot score increased significantly from preoperative (55.6±8.8) points to (92.3±2.6) points at the last follow-up ( P<0.05). The stress test for the stability of the transverse tarsal joint showed joint stability. Conclusion:Reconstruction of the calcaneocuboid and calcaneonavicular ligaments using the autologous semitendinosus is an alternative treatment for patients with chronic bifurcate ligament injury, because it can restore the stability of the bifurcate ligament and obviously improve the foot and ankle functions with limited postoperative complications.

ABSTRACT

Objective:To establish a prediction model of acute gastrointestinal injury (AGI) above grade II in elderly patients with severe pneumonia, and to evaluate and validate the model internally.Methods:A retrospective analysis was performed on 268 patients aged >65 years with severe pneumonia admitted to the Second People′s Hospital of Hefei from June 2019 to May 2022 (207 cases in the training set and 61 cases in the verification set). Sixteen indicators, including age, sex, underlying disease, pneumonia Severity index (PSI) score, dosage of sedative and analgesic drugs, and mechanical ventilation time of all patients were collected. After logistic regression analysis in the training set, a model was established to predict AGI above grade Ⅱ in elderly patients with severe pneumonia. Receiver operating characteristic (ROC) curve was drawed and correction curve was used to evaluate the reliability of the model. The model was internally validated by validation set data.Results:Among 207 patients with severe pneumonia in the training set, 50 patients developed AGI above grade Ⅱ during treatment. The prediction model was established by logistic regression analysis as follows: When L=Sequential Organ Failure Assessment (SOFA)×0.181+ PSI score×0.066+ propofol dosage×0.607+ reifentanil dosage×1.187, L>19.288, it can be considered that patients with severe pneumonia have a 93.24% chance of developing grade Ⅱ or above AGI. The ROC curve showed that the model was well differentiated, AUC=0.960. H-L test indicated (χ 2=7.39, P=0.496>0.05) the model fit was good. The sensitivity and specificity of the model were 82.00% and 96.82% respectively. AUC=94.58% (sensitivity 81.25%, specificity 93.33%), H-L test indicated ( χ 2=4.51, P=0.808>0.05) the prediction accuracy was 90.16%. Conclusions:The prediction model for AGI after severe pneumonia in elderly patients can be used clinically to help predict the occurrence of AGI in elderly patients with multiple injuries.

ABSTRACT

【Objective:】 To explore the practice experience of narrative medicine among postgraduates majoring in Traditional Chinese Medicine (TCM) and its impact on their professional identity. 【Methods:】 A total of 56 first-year master’s and doctoral degree students majoring in TCM at a university were selected through purposive sampling for a 16-hour narrative medicine course training and 4 weeks of clinical practice in narrative medicine. They were asked to complete an open-ended writing assignment on their practical experience after this clinical practice. Subsequently, the topic analysis method in qualitative research was used to analyze their writing contents. 【Results:】 After learning narrative medicine, the students’ practical experience in clinical practice included 3 major themes and 9 sub-themes: wide application range (all diagnosis and treatment stages, multiple departments, and disease types), integration of multiple communication skills and diagnosis and treatment methods (communication skills, psychological techniques, reflection, and TCM humanistic diagnosis and treatment methods), and increasing professional identity (achieving mutual healing, building the harmonious doctor-patient relationship, and enhancing confidence in TCM). The themes were further integrated to form the relationship between the narrative medical practice cycle and professional identity, and presented in the form of charts. 【Conclusion:】 By exploring the narrative medical practice experience among TCM postgraduates, it was found that through the use of multiple methods and techniques in the entire diagnosis and treatment stage and multi-disciplinary diseases, it is possible to harmonize the doctor-patient relationship, achieve mutual healing, and enhance confidence in TCM. These internalized recognition and sense of achievement contributes to improving professional identity, which may provide new ideas for the development of professional identity for medical students in China and the exploration of the localization of narrative medical practice.

ABSTRACT

Objective:To investigate the clinical significance of prognostic serum marker expression in older adult patients with sepsis-associated encephalopathy (SAE).Methods:The clinical data of 79 older adult patients with SAE who received treatment in The Second People's Hospital of Hefei from June 2019 to February 2021 (study group) and 121 sepsis patients without encephalopathy concurrently (control group) were retrospectively analyzed. The indexes with statistically significant difference between the two groups were subjected to multivariate binary logistic regression. Survival curve was plotted.Results:There were no significant differences in neuron specific enolase [NSE, (10.69 ± 4.31) μg/L vs. (24.84 ± 3.28) μg/L, t = 26.25, P < 0.01], S100β [(0.25 ± 0.06) μg/L vs. (0.53 ± 0.09) μg/L, t = 22.45, P < 0.01], monocyte chemoattractant protein-1 [MCP-1, (99.33 ± 4.87) ng/L vs. (179.99 ± 6.02) ng/L, t = 99.94, P < 0.01], malondialdehyde [MDA, (4.22 ± 0.08) nmol/L vs. (6.78 ± 0.11) nmol/L, t = 33.76, P < 0.01], glial fibrillary acidic protein [GFAP, (0.21±0.08) μg/L vs. (2.03 ± 0.47) μg/L, t = 33.76, P < 0.01], procalcitonin [(7.04 ± 2.50) ng/L vs. (16.23 ± 2.48) ng/L, t = 25.47, P < 0.01], interleukin-6 [(29.91 ± 4.51) ng/L vs. (69.22 ± 6.79) ng/L, t = 45.51, P < 0.01], Acute Physiology and Chronic Health Evaluation II (APACHE II) score [(18.33 ± 2.12) points vs. (28.89 ± 5.09) points, t = 17.53, P < 0.01], and sequential organ failure assessment score [(7.69 ± 1.50) points vs. (14.05 ± 1.55) points, t = 28.92, P < 0.01] between the control and study groups. N-terminal pro B-type natriuretic peptide was (868.38 ± 25.28) ng/L and (1 037.19 ± 25.34) ng/L in the control and study groups, respectively. Logistic regression analysis revealed that NSE, MCP-1, MDA, and GFAP were the independent risk factors for developing SAE in older adults (NSE: t = 8.42, P < 0.01; MCP-1: t = 4.16, P < 0.01; MDA: t = 18.4, P < 0.01; GFAP: t = 2.88, P < 0.01). The survival curve indicated that survival rate was significantly lower in the study group than in the control group. Conclusion:NSE, MCP-1, MDA, and GFAP are independent risk factors for developing SAE in older adults.

ABSTRACT

β-amyloid protein (Aβ) is produced from β-amyloid precursor protein under the action of β-secretase and γ-secretase. Aβ accumulates and aggregates, forms oligomers and fibrils, and deposits in the brain, leading to functional neuronal death and cognitive impairment. β- amyloid protein induces inflammatory response, oxidative stress, free radical damage, calciumion disorder and so on, resulting in neuronal necrosis and apoptosis. Recent studies show that β-amyloid also plays an important role in hypoxia/ischemic brain injury. We review the mechanism of β-amyloid protein in hypoxic/ischemic brain injury.

ABSTRACT

ObjectiveTo study the effect of organophosphate-solubilizing bacteria and compound bacteria on the photosynthesis and physiological and biochemical characteristics of leaves of Paris polyphylla var. yunnanensis, and to provide a reference for selecting suitable bacterial fertilizers in artificial cultivation of this medicinal species. MethodPot experiment was carried out indoor and the following groups were designed: control (CK), inoculation with Bacillus mycoides (S1), inoculation with B. wiedmannii (S2), inoculation with B. proteolyticus (S3), inoculation with B. mycoides and B. wiedmannii (S4), inoculation with B. mycoides and B. proteolyticus (S5), inoculation with B. wiedmannii and B. proteolyticus (S6), and inoculation with B. mycoides, B. wiedmannii and B. proteolyticus (S7). Then, the growth and development, photosynthesis, and various physiological and biochemical indexes of the leaves of this species were observed. ResultCompared with CK, the treatment groups showed decrease in content of malondialdehyde in the leaves (P<0.05), particularly S7 (content was only about 1/3 that of the CK). The leaf area, photosynthetic parameters, photosynthetic pigment content, soluble sugar content, soluble protein content, and activity of superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT) in leaves of the treatment groups were all improved. Among them, the leaf area, soluble sugar content, and soluble protein content were the highest in S7, which were 2.8, 2.1, and 2.2 times that of the CK, respectively. SOD activity peaked in S6 (2.9 times higher than that in the CK) and the highest activity of POD and CAT was detected in S5 (1.5 times and 2.1 times, respectively higher than that in the CK). ConclusionInoculation with different organophosphate-solubilizing bacteria or compound bacteria can promote the growth and development of P. polyphylla var. yunnanensis and improve its resistance to stresses. The combination of B. mycoides and B. proteolyticus and the combination of the three achieved the have the best effect. This study provides a reference for the selection of bacterial fertilizers for artificial cultivation of P. polyphylla var. yunnanensis.

ABSTRACT

Objective:To investigate the prevalence of deep vein thrombosis (DVT) in patients after selective ankle or mid-hindfoot surgery.Methods:A retrospective analysis was conducted of the 109 patients with ankle or mid-hindfoot disease who had been treated from January 2018 to December 2019 at Department of Orthopaedics, Wuhan Fourth Hospital. They were 65 males and 44 females, aged from 32 to 74 years (average, 49.0 years). Ultrasonography was performed at preoperative 1 day, postoperative 2 and 6 weeks to determine the occurrence, location and clinical symptoms of DVT. The patients were divided into an early DVT group, a late DVT group and a DVT-free group according to the occurrence and onset time of DVT. The 3 groups were compared in terms of gender, age, body mass index and tourniquet duration.Results:The incidence of postoperative lower limb DVT was 22.9% (25/109). All the thromboses were observed beyond the distal plane of the popliteal vein. 72.0% of the DVT patients were clinically asymptomatic. There was no significant difference in gender, age or body mass index between early DVT group ( n=17), late DVT group ( n=8) and DVT-free group ( n=84) ( P>0.05). The incidence was 68.0% (17/25) for early DVT and 32.0% (8/25) for late DVT. The intraoperative tourniquet duration for the early DVT group [(77.7±12.3) min] was significantly longer than that for the late DVT group [(66.8±11.2) min] and for the DVT-free group [(65.9±10.5) min] ( P<0.05). Conclusions:The majority of postoperative DVTs may be clinically asymptomatic in patients after selective ankle or mid-hindfoot surgery. Although DVT tends to occur within postoperative 2 weeks, its risk may continue after 2 weeks. Increased tourniquet duration may be associated with incidence of early DVT.

ABSTRACT

Objective:To compare the therapeutic effects between sequential therapy of external-internal fixation and internal fixation alone in the treatment of high-energy pilon fracture.Methods:A total of 61 patients with high-energy pilon fracture were enrolled by our team for this retrospective analysis who had been treated from January 2015 to July 2017. They received sequential therapy of external-internal fixation (the sequential group) or internal fixation alone (the internal group). In the sequential group of 26 cases, there were 19 males and 7 females (aged from 18 to 65 years), 4 cases of type C1, 8 cases of type C2 and 14 cases of type C3 by the OTA classification, and 7 cases of closed injury and 19 cases of open injury. In the internal group of 35 cases, there were 25 males and 10 females (aged from 19 to 64 years), 6 cases of type C1, 13 cases of type C2 and 16 cases of type C3 by the OTA classification, and 21 cases of closed injury and 14 cases of open injury. The 2 groups were compared in terms of postoperative infection, fracture reduction, fracture union time, nonunion, American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, short form 36 health survey questionnaire (SF-36) and reduced range of motion between healthy and affected ankles.Results:There was no significant difference between the 2 groups in gender, age, fracture type, injury cause or follow-up time ( P>0.05), but a significant difference in soft tissue injury favoring the sequential group ( P=0.010). There were no significant differences between the 2 groups in postoperative infection rate [15.4% (4/26) versus 17.1% (6/35)], fracture reduction, fracture union time [(7.4±3.4) months versus (6.5±3.2) months], nonunion rate [7.7% (2/26) versus 8.6% (3/35)], AOFAS ankle-hindfoot score (71.7±29.4 versus 74.4±19.5), or SF-36 (83.1±9.9 versus 83.8±7.9) ( P>0.05). The reduced range of motion between healthy and affected ankles at 6 months postoperation in the sequential group (34.6°±7.2°) was significantly greater than that in the internal group (23.7°±5.1°) ( P<0.05), but there was no significant difference between the 2 groups in the reduced range of motion between healthy and affected ankles at 2 years postoperation (26.0°±11.1° versus 21.8°±11.3°) ( P>0.05). Conclusion:Although both sequential therapy of external-internal fixation and internal fixation alone can lead to fine clinical efficacy in the treatment of high-energy pilon fracture, the former may be more suitable for the patients with severe soft tissue injury.

ABSTRACT

Objective:To investigate the therapeutic effect of tissue transplantation combined with Ilizarov distraction technique in reconstruction of lower limb anatomical structure and the recovery of lower limb functions.Methods:From October, 2010 to April, 2019, tissue transplantation combined with Ilizarov distraction technique was used to reconstruct the anatomical structures and functions of 51 lower limb defects, including 17 in proximal tibia, 27 in distal tibia, 4 partial defects of calcaneus and 3 in metatarsal bones. Surgical operations were carried out in 2 phases. Transplantation of free flaps to cover the wound surface was performed in the first phase. Thirty-three free anterolateral femoral flaps, 8 groin flaps, 5 anterolateral medial femoral flaps, 3 thoracic umbilical flaps, and 2 alissimus dorsi musculocutaneous flaps were transplanted, with the sizes ranged from 3.5 cm×15.0 cm to 8.0 cm×25.0 cm. In the second phase, Ilizarov ring rack or customer-designed distractor were applied/employed and 44 cases applied with Ilizarov ring racks and 7 cases with self-designed distractors. Regular postoperative followed-up.Results:All flaps survived. There was 1 partial necrosis on the anterolateral femoral flap and 3 postoperative infections. Bone transport was applied to repair 36 tibia defects, bone transport combined with limb extension to restore the length of limb in 8 cases, bone transverse or longitudinal distraction was applied to restore the shape of calcaneus in 4 cases, and longitudinal or transverse distraction was applied to restore the foot arch in 3 cases with metatarsal defects. Followed-up for 9 months to 2 years. There was no recurrence of osteomyelitis after the second operation. Bone healings were achieved in the articulation ends and extension areas of bone transport. The excellent rate of Paley bone score was 98.0%, the average SF-36 score was 88.9, and the average AOFAS score was 79.5.Conclusion:Tissue transplantation together with the Ilizarov technology is able to reconstruct a combined bone and soft tissue defect of lower limb and restore functions of the affected limb to the greatest extent.

ABSTRACT

A case of asymptomatic COVID-19 in a pregnant woman in the third trimester with good maternal and infant outcomes is reported. The patient was admitted to the Second People's Hospital of Hefei on February 11, 2020, because of a "positive novel coronavirus nucleic acid test result for one day" at 38 weeks of gestation. No abnormality was observed during her previous regular prenatal examinations. A throat swab sample was obtained from the patient before admission due to the diagnosis of COVID-19 in her husband and sister on the 14 th and 7 th day before her admission, and the new coronavirus nucleic acid test showed positive. The patient reported no discomfort before admission. Chest CT on the 3 rd day after admission showed a small amount of bilateral pleural effusion. Irregular contractions occurred three days after admission and then, an emergency cesarean section was performed and the patient delivered a live baby girl. No tests were performed on amniotic fluid, cord blood or placenta for new coronavirus nuclei acid. The patient was isolated from the infant without breastfeeding after surgery. All medical staff involved in the cesarean section were isolated after surgery. Neonatal peripheral blood and nasopharyngeal swabs were collected for the new coronavirus nucleic acid tests on the day of birth and one day of age, respectively, and nasopharyngeal swabs and anal swabs were taken at nine days after birth. All test results were negative. The patient recovered well after surgery with stable vital signs. Chest CT on the 8 th day after operation showed a small amount of bilateral pleural effusion, while the new coronavirus nucleic acid test results of the pharyngeal swabs were positive on the 11 th and 12 th day after operation. The throat swabs of all medical staff involved in the operation were negative 14 days after the operation. The mother and baby were discharged 14 days after the cesarean section.

ABSTRACT

Objective:To evaluate the effect of definitive radiotherapy with different doses on overall survival (OS) and identify the prognostic factors of patients with non-metastatic esophageal squamous cell carcinoma (ESCC).Methods:Clinical data of 2 344 ESCC patients treated with definitive radiotherapy (RT) alone or chemoradiotherapy from 2002 to 2016 in 10 hospitals were collected and analyzed retrospectively. After the propensity score matching (PSM)(1 to 2 ratio), all patients were divided into the low-dose group (equivalent dose in 2 Gy fractions, EQD 2Gy<60 Gy; n=303) and high-dose group (EQD 2Gy≥60 Gy; n=606) based on the dose of radiation. Survival analysis was conducted by Kaplan- Meier method. Multivariate prognostic analysis was performed by Cox′s regression model. Results:The median follow-up time was 59.6 months. After the PSM, the 1-, 3- and 5-year overall survival (OS) rate was 66.5%, 34.7%, 27.2% in the low-dose group, 72.9%, 41.7% and 34.7% in the high-dose group, respectively ( P=0.018). The 1-, 3-and 5-year progression-free survival rate was 52.2%, 27.2%, 23.1% in the low-dose group, 58.3%, 38.1% and 33.9% in the high-dose group, respectively ( P=0.001). The outcomes of univariate analysis indicated that cervical/upper esophagus location, early (stage Ⅱ) AJCC clinical stage, node negative status, tumor length ≤5 cm, receiving intensity-modulated radiation therapy (IMRT), receiving concurrent chemotherapy and EQD 2Gy≥60 Gy were closely associated with better OS (all P<0.05). Multivariable analysis demonstrated that tumor location, regional lymph node metastasis, concurrent chemotherapy and EQD 2Gy were the independent prognostic factors for OS (all P<0.05). Conclusion:Three-dimensional conformal or IMRT with EQD 2Gy≥60 Gy yields favorable survival outcomes for patients with locally advanced ESCC.

ABSTRACT

Concurrent chemoradiotherapy is widely accepted as the standard treatment for locally advanced inoperable esophageal cancer, and 50.0 to 50.4 Gy is recommended as the optimal dose for definitive treatment by the international guidelines. However, esophageal cancer in China is quite different from that in western countries in terms of the pathological type and biological characteristics, and a radiation dose of 60 Gy is recommended. Whether dose-escalated radiotherapy could bring survival benefits remains to be urgently resolved. Some scholars indicate that the higher radiation dose is correlated with better local tumor control and more favorable survival outcomes, whereas others hold the view that increased toxicity and no survival benefits have been observed in the high dose arm. Therefore, this review is to evaluate the impact caused by different radiation doses and assess the clinical efficacy, aiming to individualize the radiation dose.

ABSTRACT

Objective:To report our experience in the emergent foot and ankle surgery in the epidemic of COVID-19.Methods:The data of 18 patients with acute foot and ankle injury were reviewed who had been admitted to the Department of Foot and Ankle Surgery, Wuhan Fourth Hospital from 20th January, 2020 to 26th February, 2020. They were 11 men and 7 women, aged from 18 to 70 years (average, 42.5 years). There were 5 cases of acute open injury and 13 ones of acute closed injury. COVID-19 infection was diagnosed or suspected in 5 cases but not in the other 13 cases. Emergency operation was carried out for 2 patients with open injury plus COVID-19 infection and one with complicated pilon fracture plus COVID-19 infection, one of whom received secondary operation. One patient with closed fracture of the left calcaneus plus COVID-19 infection was hospitalized from emergency department for secondary surgery, and another with closed fracture of the right lateral malleolus was referred to the isolation ward after emergency plaster fixation. Of the 10 patients with closed injury but without COVID-19 infection, 3 received conventional secondary surgery after admission and the others conservative treatment at the outpatient department. Recorded were COVID-19 infections in the patients after admission and in the medical staff. The measures taken and experience in control and prevention of COVID-19 infection after outbreak of the epidemic were reviewed.Results:Of the 11 patients who had been hospitalized for foot and ankle injury in emergency, 5 were definitely diagnosed of or suspected of COVID-19 infection and 6 free of COVID-19 infection. During hospitalization, COVID-19 infection was confirmed in the 5 cases and no COVID-19 infection occurred in the other 6 patients. No COVID-19 infection occurred in the medical staff; no cross infection was observed between the patients and the medical staff.Conclusions:Reasonable strategies are advised to balance the foot and ankle surgery and epidemic prevention. A simplified management is not advised for all the cases. The operative procedures in emergent foot and ankle surgery should be optimized in line with the epidemic control and prevention principles to facilitate functional rehabilitation for the patients.

ABSTRACT

There are various bacterial colonies in the human intestine, which play an important role in the maintenance of human intestinal function and the maintenance of the systemic immune system. After years of research, researchers have found that intestinal flora are closely related to a variety of inflammatory and immune diseases. In recent years, immunotherapy has attracted more and more attention in the treatment of malignant tumors. In these immunotherapy researches, researchers have found that the composition and changes of intestinal flora can affect the efficacy of tumor immunotherapy to a certain extent. In this paper, the literatures related to intestinal flora and tumor immunotherapy were reviewed from four aspects including the relationship between intestinal flora and body's immune mechanism, current status of tumor immunotherapy, correlation research between intestinal flora and tumor immunotherapy, and related factors that affect changes in intestinal flora composition. The researches on intestinal flora and tumor immunotherapy in the past ten years were mainly summarized. The analysis results showed that the intestinal flora plays an important role in the body's immune mechanism and is closely related to the efficacy of tumor immunotherapy.
