ABSTRACT

Abstract@#Allergic diseases can occur in all systems of the body, covering the whole life cycle, from children to adults and to old age, can be lifelong onset and even fatal in severe cases. Children account for the largest proportion of the victims of allergic disease, Children s allergies start from scratch, ranging from mild to severe, from less to more, from single to multiple systems and systemic performance, so the prevention and treatment of allergic diseases in children is of great importance, which can not only prevent high risk allergic conditions from developing into allergic diseases, but also further block the process of allergy. At present, there is no consensus on the management system of allergic children in kindergartens and primary schools. The "Consensus on Allergy Management and Prevention in Kindergartens and Primary Schools", which includes the organizational structure, system construction and management of allergic children, provides evidence informed recommendations for the long term comprehensive management of allergic children in kindergartens and primary schools, and provides a basis for the establishment of the prevention system for allergic children.

ABSTRACT

Objective To verify the biomechanical stability of oblique lateral interbody fusion ( OLIF) combinedwith different fixation methods for treating degenerative lumbar scoliosis (DLS) by three-dimensional (3D) finite element analysis. Methods The L1-S1 3D finite element DLS model ( Model 1) was established, and then the OLIF (L2-5) at 3 contiguous levels of fusion and its combination with different internal fixation methods were simulated, namely, stand-alone OLIF model ( Model 2), vertebral screw fixation model ( Model 3), unilateral pedicle screw fixation model (Model 4) and bilateral pedicle screw fixation model (Model 5) were established,respectively. Under upright, flexion, extension, lateral bending and axial rotation states, range of motion (ROM) of fusion segments, as well as cage stress, internal fixation stress, and stress distribution were recorded and analyzed. Results Under six motion states, the overall ROM of fusion segments in Models 2-5 was smaller than that of Model 1. Compared with Model 1, the overall ROM reduction of Model 3 and Model 4 was larger than that of Model 2 and smaller than that of Model 5. Under flexion and extension, the overall ROM reduction of Model 4 and Model 5 was basically equal. Under left and right lateral bending, the overall ROM reduction of Model 3 and Model 5 was basically equal. Under all motion states, the peak stress of Model 3 and Model 4 fusion cage was larger than that of Model 5 and smaller than that of Model 2. The peak stresses of L2-3, L3-4 and L4-5 fusion cages in Model 3 increased by 5. 52% , 10. 96% and 7. 99% respectively compared with Model 5 under left lateral bending, and the peak stresses of L2-3, L3-4 and L4-5 fusion cages in Model 4 increased by 8. 70% , 7. 00% and 6. 99% respectively under flexion. Under all motion states, the peak stress of screw rod in Model 5 was smaller than that of Model 3 and Model 4, and the peak stresses of screw rod in Models 3-5 were the smallest in upright state. Conclusions The OLIF with unilateral pedicle screw fixation or vertebral screw fixation can provide favorable biomechanical stability of the fusion segment. The results provide some references for clinical application of OLIF technology in the treatment of DLS.

ABSTRACT

Infectious bone defect is bone defect with infection or as a result of treatment of bone infection. It requires surgical intervention, and the treatment processes are complex and long, which include bone infection control,bone defect repair and even complex soft tissue reconstructions in some cases. Failure to achieve the goals in any step may lead to the failure of the overall treatment. Therefore, infectious bone defect has been a worldwide challenge in the field of orthopedics. Conventionally, sequestrectomy, bone grafting, bone transport, and systemic/local antibiotic treatment are standard therapies. Radical debridement remains one of the cornerstones for the management of bone infection. However, the scale of debridement and the timing and method of bone defect reconstruction remain controversial. With the clinical application of induced membrane technique, effective infection control and rapid bone reconstruction have been achieved in the management of infectious bone defect. The induced membrane technique has attracted more interests and attention, but the lack of understanding the basic principles of infection control and technical details may hamper the clinical outcomes of induced membrane technique and complications can possibly occur. Therefore, the Chinese Orthopedic Association organized domestic orthopedic experts to formulate An evidence-based clinical guideline for the treatment of infectious bone defect with induced membrane technique ( version 2023) according to the evidence-based method and put forward recommendations on infectious bone defect from the aspects of precise diagnosis, preoperative evaluation, operation procedure, postoperative management and rehabilitation, so as to provide useful references for the treatment of infectious bone defect with induced membrane technique.

ABSTRACT

Objective:To investigate the risk factors of acute lung injury (ALI) caused by Staphylococcus aureus infection, and to construct a risk warning model. Methods:Patients with Staphylococcus aureus infection confirmed by sputum or blood culture admitted to the Affiliated Hospital of Jiangnan University from January 1, 2020 to May 10, 2022 were enrolled and divided into ALI group and non-ALI group. The age, smoking status, C-reactive protein (CRP), procalcitonin (PCT), neutrophil-to-lymphocyte ratio (NLR), albumin, oxygenation index and other clinical data were compared between the two groups. Univariate analysis was performed by using independent sample t test and chi-square test. Binary logistic regression analysis was used to screen the independent risk factors of ALI caused by Staphylococcus aureus infection, and a risk warning model was constructed. The receiver operator characteristic (ROC) curve was used to evaluate the predictive ability of the model. Results:There were 96 cases of Staphylococcus aureus infection, including 68 cases (70.8%) in ALI group, of which 41 cases (60.3%) were positive in sputum culture and 27 cases (39.7%) were positive in blood culture. Compared with the non-ALI group, the proportion of patients aged ≥60 years in ALI group was lower (58.8%(40/68) vs 64.3%(18/28)), the proportion of smoking was higher (58.8%(40/68) vs 35.7%(10/28)), and the differences were both statistically significant ( χ2=0.76 and 0.03, respectively, both P<0.05). The levels of CRP, PCT and NLR in the ALI group were all higher than those in non-ALI group, while oxygenation index and albumin level were both lower, and the differences were all statistically significant ( t=-5.28, -3.46, -9.87, 12.83 and 3.08, respectively, all P<0.05). Binary logistic regression analysis showed that CRP (odds ratio ( OR)=1.973, 95% confidence interval (95% CI) 0.956 to 2.989), PCT ( OR=3.734, 95% CI 1.014 to 13.746), NLR ( OR=1.152, 95% CI 1.058 to 2.254) and albumin ( OR=1.527, 95% CI 1.110 to 2.102) were independent risk factors for ALI caused by Staphylococcus aureus infection. The areas under the ROC curve of CRP, PCT, NLR, albumin and the risk warning model constructed from the combination of four risk factors were 0.69, 0.81, 0.83, 0.78 and 0.93, respectively. The sensitivities were 65.14%, 89.91%, 84.40%, 56.88% and 98.17%, respectively. The specificities were 62.37%, 60.22%, 65.59%, 80.64% and 93.55%, respectively. The accuracy of the effectiveness test of the risk warning model was 84.97%. Conclusions:CRP, PCT, NLR and albumin are the independent risk factors for ALI caused by Staphylococcus aureus infection. The risk warning model based on the above factors has a good early warning effect on ALI caused by Staphylococcus aureus infection.

ABSTRACT

Objective:To investigate the application value of percutaneous coronary intervention in patients with acute coronary syndrome in county-level hospitals.Methods:The clinical data of 51 patients with acute coronary syndrome who received treatment in Feng Tai People's Hospital from January 2020 to January 2022 were retrospectively analyzed. They were divided into a control group ( n = 25) and an observation group ( n = 26). The control group was given standard dual antiplatelet and statin drugs. The observation group underwent percutaneous coronary intervention and stent implantation based on conventional drug treatment. All patients were followed up for 1 year. Cardiac function indexes left ventricular ejection fraction (LVEF) and left ventricular end-diastolic diameter (LVEDD) were compared between the two groups. The number of readmissions, length of hospital stay, quality of life score, medication, the incidence of complications, and the incidence of adverse cardiovascular events were compared between the two groups. Results:Before treatment, there were no significant differences in LVEF and LVEDD between the two groups (both P > 0.05). After treatment, LVEF was increased, and LVEDD was decreased in each group compared with before treatment. After treatment, LVEF and LVEDD in the observation group were (50.34 ± 5.97)% and (49.01 ± 5.02) mm, respectively, which were significantly superior to (45.61 ± 5.42)% and (52.12 ± 5.24) mm in the control group ( t = -2.96, 2.17, both P < 0.05). After treatment, the number of readmissions in the observation group was significantly less than that in the control group [(0.8 ± 0.1) times vs. (2.1 ± 0.3) times, t = 20.14, P < 0.001]. The length of hospital stay in the observation group was significantly shorter than that in the control group [(12.4 ± 3.1) days vs. (25.3 ± 3.9) days, t = 13.10, P < 0.001]. Quality of life score in the observation group was significantly higher than that in the control group [(85.3 ± 5.9) points vs. (72.5 ± 5.2) points, t = -8.19, P < 0.001]. After treatment, the incidence of adverse cardiovascular events in the observation group was significantly lower than that in the control group [3.9% (1/26) vs. 28.0% (7/25), χ2 = 3.94, P = 0.041). Conclusion:Use of percutaneous coronary intervention in patients with acute coronary syndrome in county-level hospitals is feasible. It can improve patients' cardiac function and has a remarkable clinical effect with a low incidence of adverse cardiovascular events.

ABSTRACT

Accumulating evidence has confirmed the links between transfer RNA (tRNA) modifications and tumor progression. The present study is the first to explore the role of tRNA methyltransferase 5 (TRMT5), which catalyzes the m1G37 modification of mitochondrial tRNAs in hepatocellular carcinoma (HCC) progression. Here, based on bioinformatics and clinical analyses, we identified that TRMT5 expression was upregulated in HCC, which correlated with poor prognosis. Silencing TRMT5 attenuated HCC proliferation and metastasis both in vivo and in vitro, which may be partially explained by declined extracellular acidification rate (ECAR) and oxygen consumption rate (OCR). Mechanistically, we discovered that knockdown of TRMT5 inactivated the hypoxia-inducible factor-1 (HIF-1) signaling pathway by preventing HIF-1α stability through the enhancement of cellular oxygen content. Moreover, our data indicated that inhibition of TRMT5 sensitized HCC to doxorubicin by adjusting HIF-‍1α. In conclusion, our study revealed that targeting TRMT5 could inhibit HCC progression and increase the susceptibility of tumor cells to chemotherapy drugs. Thus, TRMT5 might be a carcinogenesis candidate gene that could serve as a potential target for HCC therapy.

ABSTRACT

To explore the mechanism of ovarian toxicity of Hook. F. (TwHF) by network pharmacology and molecular docking. The candidate toxic compounds and targets of TwHF were collected by the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) and the Comparative Toxicogenomics Database (CTD). Then, the potential ovarian toxic targets were obtained from CTD, and the target genes of ovarian toxicity of TwHF were analyzed using the STRING database. The protein-protein interaction (PPI) network was established by Cytoscape and analyzed by the cytoHubba plug-in to identify hub genes. Additionally, the target genes of ovarian toxicity of TwHF were subjected to Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses by using the R software. Finally, Discovery Studio software was used for molecular docking verification of the core toxic compounds and the hub genes. Nine candidate toxic compounds of TwHF and 56 potential ovarian toxic targets were identified in this study. Further network analysis showed that the core ovarian toxic compounds of TwHF were triptolide, kaempferol and tripterine, and the hub ovarian toxic genes included , , , , , , , , and . Besides, the GO and KEGG analysis indicated that TwHF caused ovarian toxicity through oxidative stress, reproductive system development and function, regulation of cell cycle, response to endogenous hormones and exogenous stimuli, apoptosis regulation and aging. The docking studies suggested that 3 core ovarian toxic compounds of TwHF were able to fit in the binding pocket of the 10 hub genes. TwHF may cause ovarian toxicity by acting on 10 hub genes and 140 signaling pathways.

ABSTRACT

Objective:To explore the clinical efficacy of vascular interventional therapy in children with transplantation renal artery stenosis(TRAS).Methods:From January 2013 to September 2021, retrospective analysis was performed for clinical data of 238 TRAS children.Peak systolic velocity(PSV)of transplant renal artery, interlobular artery PSV, transplant renal artery PSV/ interlobular artery PSV(post PSV ratio)and serum creatinine level before and after vascular interventional therapy and at the last follow-up were compared.Results:Six pediatric kidney transplantation recipients were diagnosed as TRAS.The median operative age was 12(9-17)years, the median postoperative time to diagnosing TRAS 4(1.7-18.0)months and the median follow-up period 6.6(2.5-8.0)years.All of them received vascular interventional therapy of percutaneous transluminal angioplasty(PTA, n=5)and stent angioplasty( n=1). The serum creatinine pre-treatment with vascular interventional therapy was significantly higher than baseline serum creatinine level at discharge(200.8±88.5)vs(75.2±27.9)μmol/L, P=0.025 and decreased to(103.8±44.7)μmol/L at Month 1 post-treatment( P=0.196)and(98.7±30.2)μmol/L at the last follow-up( P=0.115). Comparing with internal diameter of grafted renal artery anastomosis site(2.6±0.6 mm)pre-treatment with vascular interventional therapy, significant changes occurred at 24 h post-treatment(3.8±0.5 mm)and at the last follow-up(4.1±0.8 mm)(all P=0.027). In addition, PSV and post PSV ratio of transplanted renal artery at 24 h post-treatment(163±45.0 cm/s, 6.5±2.2)and at the last follow-up(184.7±80.8 cm/s, 5.4±2.0)were significantly lower than that before vascular interventional therapy(356.5±77.9 cm/s, 18.0±5.8)and interlobular artery PSV was significantly higher than that before vascular interventional therapy( P=0.024, P=0.032, respectively). During follow-ups, no restenosis or thrombosis occurred in transplanted renal arteries. Conclusions:PTA or stent angioplasty for TRAS children is technically feasible with low restenosis rate and relatively satisfactory mid/long-term outcomes.

ABSTRACT

Objective:To analyze the health literacy level among medical staff and its influencing factors.Methods:Using the convenient sampling method, the in-service medical staff from four medical institutions (Shanghai Pudong New Area People′s Hospital, Shanghai Pudong New Area Zhoupu Hospital, Shanghai Tenth People′s Hospital Chongming Branch, and Shanghai Jing′an District Zhabei Central Hospital) were administered with a national residents′ health literacy questionnaire uniformly compiled by the China Health Education Center, and an electronic questionnaire independently compiled in combination with professional characteristics of the medical staff. The survey period was January 5-17, 2021. The contents of the questionnaire included basic information regarding gender, age, education, and professional title. Respondents were also asked whether they had chronic diseases, and three aspects of health literacy for basic knowledge and concepts, healthy lifestyle and behavior and health skills covering six other types of health problems including scientific outlook on health, infectious disease prevention and control literacy, chronic disease prevention and control. Safety and first aid literacy, basic medical literacy, health information literacy were also assessed. The total score for the questionnaire was 100 points. Respondents with a score of 80 or more were considered to have a competent health literacy. A total of 870 questionnaires were distributed, excluding incomplete ones, 826 valid questionnaires were used for analysis. Logistic regression was used to analyze factors influencing the health literacy among medical staff.Results:The overall health literacy level of medical staff was 64.0%, with 79.7% of respondents indicating that they had basic knowledge and concepts, 70.8% indicating that they practiced healthy lifestyles and behaviors, and 33.5% showed proficiencies in terms of health skills. From high to low, the health literacy levels for the six types of health problems were safety and first aid literacy (80.5%), scientific outlook on health (76.4%), infectious disease prevention and control literacy (60.2%), chronic disease prevention and control literacy (70.9%), basic medical literacy (52.7%), and health information literacy (50.2%). The results of a multivariate logistic regression analysis showed that physical condition, a lifestyle harmful to one′s health, highest educational background, and a professional title in the previous year were the independent influencing factors related to health literacy ( P<0.05). Conclusion:Levels of health skills, basic medical literacy, and health information literacy among medical staff are low, and physical condition in the previous year, lifestyle, professional title, and education are important factors influencing the level of health literacy among medical staff.

ABSTRACT

Objective:To investigate the effect of a degradable high-purity magnesium screw in fixing the greater trochanter bone flap of a lateral circumflex femoral artery transverse branch in the treatment of ischemic necrosis of femoral head in young and middle-aged adults.Methods:From February 2017 to February 2019, 12 cases (15 hips) of young and middle-aged patients with avascular necrosis of femoral head were treated in the Department of Orthopaedic of Affiliated Zhongshan Hospital of Dalian University. The age of patients was 30-53 years old. According to Association Research Circulation Osseous (ARCO), 2 hips were graded in stage II b, 4 in ARCO II c, 1 in ARCO III a, 5 in ARCO III b, 2 in ARCO III c and 1 in ARCO IV. The greater trochanter bone flap with a lateral circumferential vascular branch was used to fill the necrotic area, and fixed by a biodegradable high purity magnesium screw in the bone flap transfer. At 3, 6 and 12 months postoperation, the patient came to the hospital outpatient clinic for follow-up, and then were reviewed once a year. Imaging efficacy was evaluated by comparing preoperative and postoperative imaging. The Harris score and Visual Anoalogue Scale (VAS) score were tested at 12 and 24 months after surgery. The Harris score and VAS score before and after surgery were compared by Friedman test, and P<0.05 was considered statistically significant. Results:All 12 patients (15 hips) were entered in the 24-36 months of follow-up. At 12 and 24 months after surgery, Harris score was found at 87 (86, 92) and 90 (87, 92) respertively, which were both higher than that before surgery [59 (52, 74)] with a significant statistical difference ( Z=-3.743, Z=-4.473, P<0.05). However, there was no significant difference in Harris scores between 12 and 24 months after the surgery ( Z=-0.730, P>0.05). At the 12 and 24 months after surgery, VAS score was found at 3 (2, 3) and 2 (1, 3) respertively, which were both lower than that before surgery [6 (5, 6) ] with a significant statistical difference ( Z=-3.560, Z=-4.656, P<0.05). There was no statistical difference in VAS scores between 12 and 24 months after surgery ( Z=-1.095, P>0.05). X-ray and CT scan showed that the bone flaps healed well and the areas of osteonecrosis were repaired. Thirteen femoral heads were in good shape, and 2 femoral heads had further collapse of hips. No patients underwent joint replacement surgery at the time of last follow-up. Conclusion:Fixation of the greater trochanter flap of lateral circumflex femoral artery transverse branch with a degradable high-purity magnesium screw can ensure the healing of the flap at the implantation site and avoid the displacement and shedding of the flap. It is a new therapeutic option to treat the avascular necrosis of femoral head of young and middle-aged people.

ABSTRACT

Objective:To study the epidemiological characteristics and spatio-temporal aggregation of hemorrhagic fever with renal syndrome (HFRS) in Shandong Province, and to provide reference for formulating reasonable prevention and control strategies.Methods:Retrospective analysis was used to collect HFRS surveillance data and confirmed case data in Shandong Province from 2017 to 2020 in the "China Disease Prevention and Control Information System Infectious Disease Surveillance System". Geoda 1.18 software was used for global and local spatial autocorrelation analysis, SaTScan 9.6 software was used for spatio-temporal scanning analysis, and ArcGis 10.7 software was used for map drawing and visual display.Results:A total of 3 753 cases of HFRS were reported in Shandong Province from 2017 to 2020, including 56 deaths. The annual incidence rate was 1.26/100 000, 1.22/100 000, 0.75/100 000 and 0.53/100 000, respectively, with an average annual incidence rate of 0.94/100 000. The incidence of HFRS was obviously seasonal, mainly concentrated in autumn and winter from October to December, accounting for 50.41% (1 892/3 753). The age of onset was mainly 30-59 years old, accounting for 61.68% (2 315/3 753). The male to female ratio was 2.76 ∶ 1.00 (2 756 ∶ 997). The occupation distribution was mainly farmers, accounting for 81.99% (3 077/3 753). The global spatial autocorrelation analysis showed that HFRS showed spatial aggregation areas in each year from 2017 to 2020 (Moran' I = 0.38, 0.33, 0.59, 0.46, Z = 7.47, 7.23, 10.69, 8.66, P < 0.001). The local spatial autocorrelation analysis showed that "high-high" aggregation areas were mainly concentrated in central and southeast of Shandong Province, while "low-low" aggregation areas were mainly concentrated in northwest of Shandong Province. Spatio-temporal scanning analysis revealed 1 type Ⅰ agglomerations and 2 type Ⅱ aggregation areas. The type Ⅰ aggregation areas occurred from October to November 2018, covering 22 counties (districts) of 5 cities in Qingdao, Yantai, Weifang, Weihai and Rizhao. The first type Ⅱ aggregation area occurred from October to November 2017, involving 23 counties (districts) of 8 cities in Jinan, Zibo, Zaozhuang, Weifang, Jining, Tai 'an, Rizhao and Linyi. The second type Ⅱ aggregation area occurred in Jinxiang County, Jining City from February to March 2017. Conclusion:The incidence of HFRS in Shandong Province from 2017 to 2020 has obvious spatio-temporal aggregation, and the hot spots are concentrated in central and southeast of Shandong Province, which should be regarded as a key area for prevention and control of HFRS.

ABSTRACT

Objective:To investigate the effect of vector sum concept in fine-tuning posterior column screw channel via ilioinguinal approach for the treatment of bi-column acetabular fracture.Methods:A retrospective cohort study was conducted to analyze the clinical data of 42 patients with acetabular double column fracture admitted to Weifang People′s Hospital from July 2015 to May 2021, including 22 males and 20 females, aged 23-77 years [(49.3±16.3)years]. The ilioinguinal approach was used in all patients with the anterior column fixed with a plate and posterior column fixed with a lag screw. The vector sum concept was used intraoperatively to fine-tune the posterior column screw channel in 19 patients (channel fine-tuning group): namely, a 2.5 mm Kirschner wire was inserted into the bony channel of the posterior column screw under fluoroscopy of iliac oblique and obturator oblique positions; when the Kirschner wire was not located in the middle of the ischial ramus under single fluoroscopy, the vector only needed to be adjusted in one direction, with zero in the other direction; when the Kirschner wire was not located in the middle of the ischial ramus under fluoroscopy of both the iliac oblique and obturator obturator oblique positions, the sum of the deviation vectors in the two directions was calculated before fine-tuning. The vector sum concept was not used to fine-tune the posterior column channel screw in 23 patients (channel non-fine-tuning group). The time of posterior column screw placement, intraoperative blood loss, frequency of guide wire adjustment and fracture healing time were recorded and compared between the two groups. At 6 months after operation, the quality of fracture reduction and hip function were assessed by Matta score and Merle D′Aubigne-Postel score, respectively. The complications were observed.Results:All patients were followed up for 7-71 months [(35.7±8.5)months]. In channel fine-tuning group, the time of posterior column screw placement was (5.1±1.5)minutes, with intraoperative blood loss of (798.8±83.9)ml, frequency of guide wire adjustment of (1.8±0.5)times and fracture healing time of (12.4±3.2)weeks; while these parameters [(39.8±12.0)minutes, (1 119.3±172.0)ml, (5.6±1.6)times and (15.6±4.2)weeks] were significantly shorter or less in channel non-fine-tuning group ( P<0.05 or 0.01). There were no significant difference in the quality of fracture reduction and hip function between the two groups at 6 months postoperatively (all P>0.05). After operation, symptoms of lateral femoral cutaneous nerve was found in seven patients, superficial incision infection in two who was healed after debridement and dressing change, deep venous thrombosis of lower limbs in three. There was no significant difference in the incidence of postoperative complications between the two groups [channel fine-tuning group: 26%(5/19), channel non-fine-tuning group: 30%(7/23)] ( P>0.05). Conclusion:For bi-column acetabular fractures via ilioinguinal approach, application of vector and concept to fine-tune the posterior column screw channel is beneficial for rapid screw placement into the osseous channel, significant reduction of intraoperative blood loss and early fracture healing.

ABSTRACT

Background/Aims@#Conventional disease-modifying anti-rheumatic drugs have been trialed in osteoarthritis (OA). Hydroxychloroquine (HCQ), which has shown its effectiveness in rheumatoid arthritis, has been trialed for the treatment of OA; however, its efficacy and safety remain unclear. This systematic review and meta-analysis evaluate efficacy and safety of HCQ for the treatment of OA. @*Methods@#MEDLINE, EMBASE, and Cochrane Central were searched from inception through June 2020. Two reviewers independently screened for randomized controlled trials (RCTs) comparing HCQ with placebo or other active-comparators for the treatment of knee, hand, or hip OA, extracted data, and performed Cochrane risk of bias assessments. @*Results@#Six RCTs, four in hand OA, two in knee OA, consisting of 842 patients (436 in HCQ arm, 406 in control arm) were included. RCTs were conducted between 2012 and 2020, one each at UK, Netherlands, Germany, Italy, Iran, and Egypt; follow-up period ranged 24 to 52 weeks. High-quality evidence showed no clinically important pain reduction with HCQ compared to placebo/active-control in hand OA (standardized mean difference [SMD], 0.14; 95% confidence interval [CI], –0.20 to 0.48). Effect on pain reduction in knee and hand OA was small and non-significant (SMD, –0.09; 95% CI, –0.44 to 0.25). High-quality evidence showed no improvement in dysfunction with HCQ compared to placebo in hand OA patients (SMD, 0.08; 95% CI, –0.23 to 0.40). Effect on dysfunction improvement in knee and hand OA was modest and statistically non-significant (SMD, –0.20; 95% CI,–0.57 to 0.18). No improvement in quality of life was observed in hand OA. @*Conclusions@#HCQ has no benefit in reducing pain and improving physical function in hand or knee OA patients.

ABSTRACT

Objective@#To describe online learning and eye strain situation of college students during the COVID-19 outbreak, to provide a scientific basis for guiding students eye health.@*Methods@#A self-filled electronic questionnaire survey through questionnaire star was administered to college students across China. Information about online learning and eye strain of 1 046 college students during the epidemic was collected in Hefei, Anhui Province from March 16 to 20, 2020. The univariate and multivariate Logistic regression analysis were performed to analyze the association between online learning and eye strain of college students.@*Results@#The rate of eye strain during online learning was 72.1%, totally of 68.4% in 421 male students and 74.6% in 625 female students. Boys with online learning time <6 h/d, slow internet access,difficulty in understanding online class reported higher rate of eye strain than girls( χ 2=17.36,8.72,7.02, P <0.05). Freshmen reported the highest rate of slow internet access occasionally and active online class( χ 2=15.26,16.11, P <0.05), junior students reported highest rate of online learning time <6 h/d, and easy understandable online class( χ 2=15.33,32.59, P <0.05), medical college students reported higher rate of slow internet access, inactive online class than non-medical college students( χ 2=11.79,11.03, P <0.05). Multivariate Logistic regression analysis showed that odds ratio( OR ) of eye strain in females was 1.40 (1.06-1.87), compared with males; the OR of eye strain were 1.43 (1.01-2.03) and 1.54 (1.10-2.15) in the groups with online learning time 6-<8 h/d and ≥8 h/d, respectively, compared with the group with online learning time <6 h/d, the OR of eye strain in the groups with slow internet access was 2.28 (1.25-4.14), compared with students without slow internet access, the OR of eye strain in the capable to understand and difficult to understand group were 2.54 (1.73-3.74) and 5.40 (2.70-10.80) respectively, compared with the easy to understand group.@*Conclusion@#Female students, online learing time ≥ 8 h/d, slow internet access, difficult to understand class content were positively related with college students eye strain. Attention should be paid to the eye health of college students to reduce the adverse effects of online learning on vision.during the COVID-19 epidemic.

ABSTRACT

Acute myeloid leukaemia (AML) is the most common form of acute leukaemia in adults, with increasing incidence with age and a generally poor prognosis. Almost 20% of AML patients express mutant isocitrate dehydrogenase 2 (mIDH2), which leads to the accumulation of the carcinogenic metabolite 2-hydroxyglutarate (2-HG), resulting in poor prognosis. Thus, global institutions have been working to develop mIDH2 inhibitors. SH1573 is a novel mIDH2 inhibitor that we independently designed and synthesised. We have conducted a comprehensive study on its pharmacodynamics, pharmacokinetics and safety. First, SH1573 exhibited a strong selective inhibition of mIDH2 R140Q protein, which could effectively reduce the production of 2-HG in cell lines, serum and tumors of an animal model. It could also promote the differentiation of mutant AML cell lines and granulocytes in PDX models. Then, it was confirmed that SH1573 possessed characteristics of high bioavailability, good metabolic stability and wide tissue distribution. Finally, toxicological data showed that SH1573 had no effects on the respiratory system, cardiovascular system and nervous system, and was genetically safe. This research successfully promoted the approval of SH1573 for clinical trials (CTR20200247). All experiments demonstrated that, as a potential drug against mIDH2 R140Q acute myeloid leukaemia, SH1573 was effective and safe.

ABSTRACT

Objective:To evaluate the relationship between preoperative frailty and postoperative pulmonary complications (PPCs) in elderly patients undergoing thoracoscopic lobectomy.Methods:The elderly patients with non-small cell lung cancer who underwent thoracoscopic lobectomy in the Affiliated Hospital of Jiangnan University were collected.The general data, frailty status, parameters of blood and operation-related parameters were recorded.The patients were divided into PPC group and non-PPC group according to whether PPCs occurred during hospitalization, and the differences between the parameters were compared.Logistic regression analysis was used to analyze the independent risk factors for PPCs.Stratification analysis and interaction test were used to further analyze the relationship between frailty and PPCs.Results:A total of 298 elderly patients with non-small cell lung cancer undergoing thoracoscopic lobectomy were included in this study, and the incidence of PPCs was 22.8%.Compared with non-PPC group, the albumin and FEV 1/FVC were decreased, and age, blood creatinine, ratio of diabetes mellitus, ratio of chronic obstructive pulmonary disease (COPD) and rate of preoperative frailty were significantly increased in PPC group ( P<0.05). The results of logistic regression analysis showed that COPD and preoperative frailty were independent risk factors for PPCs.After adjusting all the risk variables, the frail patients had a 171% increased risk of PPCs compared with non-frail patients ( OR value=2.71, 95%CI: 1.18-4.73, P<0.05). The results of subgroup analysis showed that body mass index and operation time had effect modification on the association between frailty and PPCs (interaction P<0.05). Conclusion:COPD and preoperative frailty are independent risk factors for PPCs in elderly patients undergoing thoracoscopic lobectomy, and the frail patients with obesity or long operation time are at higher risk of PPCs.

ABSTRACT

Objective:To analyze the predictive value of enhanced MRI in the outcome of prolapsed and sequestrated lumbar disc herniation through a retrospective analysis.Methods:A retrospective analysis of the data of 64 patients with prolapsed and sequestrated lumbar disc herniation from January 2015 to December 2018, including 38 males and 26 females; age 35.72±12.44 years (range, 22-64 years) ; 43 cases of prolapsed type, 21 cases of sequestrated type. Conservative treatment was the first choice for all patients, in case of surgical indications during the treatment, percutaneous endoscopic lumbar discectomy or fenestration discectomy will be performed. Enhanced MRI was performed at the first and last inspections, the volume of the protrusion, the thickness of rim enhancement (Tr), and the extent of rim enhancement (Er) were measured and calculated at the same time. According to the ring around the protrusion, the size of the rim-enhancement area was divided into type I-III; then compared the relationship between the rim-enhancement signal differentiation and the resorption rate of protrusions, and the correlation between Tr, Er values and the resorption rate of protrusions during the initial inspection.Results:Among the 64 patients, 42 patients completed conservative treatment, and 22 received surgical treatment. According to the rim-enhancement signal differentiation, 23 cases were treated conservatively for type I, 3 cases were treated by surgery; 16 cases were treated for type II conservatively, 7 cases were treated by surgery; 3 cases were treated for type III conservatively, and 12 cases were treated by surgery. All patients were followed up for 12 to 34 months. Among 42 conservatively treated patients, The volume of the protrusion before treatment was 2 645.67±690.86 mm 3, and the volume of the protrusion after treatment was 842.76±573.35 mm 3. The volume of protrusions before and after treatment was statistical significance ( t=11.897, P<0.001), Tr was 1.38±0.83 mm, and Er was 73.08%±34.39%, the resorption rate of protrusions was 65.10%±24.50%, and 39 cases (92.86%, 39/42) reached the standard for protrusion resorption (resorption rate ≥30%); 23 cases of type I , the resorption rate was 76.54%±18.62%; 16 cases of type II had an resorption rate of 56.81%±21.44%; 3 cases of type III had an resorption rate of 21.58%±12.19%. The resorption rate of type III were compared by single factor analysis of variance, and the difference was statistically significant ( F=12.885, P<0.001); 32 cases of both type I and II (82.05%, 32/39) had significant resorption (resorption rate ≥50%), and no case of type Ⅲ had significant resorption, comparing with type I and II, the difference was statistically significant ( P=0.010); Tr was positively correlated with resorption rate ( r=0.569, P<0.001), Er was positively correlated with resorption rate ( r=0.677, P<0.001). Conclusion:Under close clinical observation, parts of the prolapsed or sequestrated lumbar disc herniations can be conservatively treated, and the herniated disc can be resorption in many people and the clinical symptoms were alleviated. Rim-enhancement signal differentiation by enhanced MR has a better predictive value for the outcome of the herniation, type I is more prone to resorption, preferred conservative treatment, type Ⅲ is not easy to resorption, preferred surgery treatment, and the higher thickness of rim enhancement, the greater extend the rim-enhancement, the more prone to resorption phenomenon.
