RESUMEN
PURPOSE: Inferior alveolar nerve injury is a common complication following mandibular third molar extraction. Accurate pre-operative assessment of the anatomical relationship between the mandibular third molar and the mandibular canal could help to avoid this injury. We performed a eta-analysis to investigate whether panoramic radiography could be used to assess the relationship between these two structures. METHODS: PubMed, EMBASE, SpringerLink, Cochrane Library, and Web of Science databases were searched independently by two researchers from January 2008 to May 2018. RESULTS: Seven articles were identified. Statistical analyses were performed using Revman 5.3 and Meta-disc 1.4 software tools. The pooled sensitivity and specificity were 0.19 (95%CI:0.16-0.22) and 0.90 (95%CI:0.88-0.92), respectively. The pooled positive likelihood ratio and negative likelihood ratio were 2.34 (95%CI:1.42-3.87) and 0.86 (95%CI:0.78-0.96), respectively. The area under the curve was 0.86 (95%CI:0.78-0.96). CONCLUSIONS: According to the sign of narrowing of the mandibular canal, panoramic radiology used to assess the relationship between the mandibular third molar and the mandibular canal yielded high specificity, but low sensitivity. The absence of narrowing of the mandibular canal indicated that there was no close contact between these two structures. However, the presence of narrowing of the mandibular canal could not be used to accurately evaluate the relationship between these two structures, although it might indicate a high probability of close anatomical contact between these two structures. Further tests should be performed for providing adequate pre-operative risk assessment while planning for the surgery to reduce the risk of inferior alveolar nerve injury, as well as to enable an open discussion with the patient to decrease the risk of medical disputes.

Objective:To explore the clinical efficacy of combined use of artificial bone materials in percutaneous vertebroplasty (PVP) for osteoporotic vertebral compression fractures (OVCF).Methods:One hundred and eighty-four consecutive patients with OVCF admitted to Beijing Friendship Hospital, Capital Medical University from June 2020 to June 2021 were retrospectively analyzed. All patients had single-level fracture and treated with PVP. According to whether artificial bone materials were used, the patients were divided into experimental group ( n=95) and control group ( n=89). The experimental group was treated with bone cement mixed with artificial bone materials, and the control group was treated with bone cement. The following indices were observed in the two groups before surgery and at 3 days, 3 months, 12 months (final follow-up) after surgery: visual analogue scale (VAS) score, Oswestry disability index (ODI), Cobb angle of kyphosis, and the percentage of anterior vertebral height, the amount of bone cement injected, postoperative complications and adjacent vertebral fractures were recorded. Measurement data were expressed as mean±standard deviation ( ± s), and t-test was used for comparison between groups; Chi- test was used for comparison between groups for count data. Results:All patients successfully completed the operation and were followed up for 12-20 months, with a mean follow-up of (14.24±2.51) months. The VAS score at 3 days, 3 months after operation and final follow-up (experimental group: 2.00±0.71, 1.89±0.71, 1.41±0.49; control group: 2.13±0.73, 1.81±0.60, 1.44±0.50) and ODI index at 3 months after operation and the final follow-up [experimental group: (21.56±4.68)%, (23.22±4.11)%; control group: (22.46±3.74)%, (22.39±4.05)%] were significantly improved compared with those before operation [VAS, experimental group: 7.66±0.86, control group: 7.81±0.89; ODI, experimental group: (70.11±8.24)%, control group: (68.97±8.59)%], and the differences were statistically significant ( P<0.05). There were no significant differences in the amount of bone cement injected between the two groups ( P>0.05). There was no significant difference in the Cobb angle of kyphosis and the percentage of anterior vertebral height at each time point ( P>0.05). The incidence of bone cement leakage in the experimental group was 15.8% (15/95), slightly lower than that in the control group [22.5% (20/89)], but the difference was not statistically significant ( P>0.05). As of the final follow-up, the incidence of adjacent vertebral fracture in the experimental group was 8.4% (8/95), which was lower than that in the control group (19.1%, 17/89), and the difference was statistically significant ( P< 0.05). Conclusion:The application of bone cement mixed with artificial bone materials in PVP for OVCF, can achieve good clinical efficacy, and reduce the incidence of adjacent vertebral fractures.

RESUMEN
Surgery is the mainstay of treatment for early lung cancers, but there is still a risk of recurrence and metastasis after surgery. With the advancement of molecular biology and detection methods, detecting the level of postoperative peripheral blood minimal residual disease (MRD) in patients can dynamically monitor recurrence and determine prognosis. Due to the wide variety of MRD detection methods, uneven detection power, lack of uniform standards and prospective study validation, clinical application is still controversial. The further development of MRD detection for early stage cell lung cancer still needs technical progress, standardized detection criteria and credible clinical data.
RESUMEN
Objective:To investigate the etiology, prognosis and clinical characteristics of abnormal serum amylase and lipase in children.Methods:This study was a retrospective study.A total of 7 813 children older than 28 days who had their serum amylase and lipase detected in Hunan Children′s Hospital from August 2017 to August 2020 were included as the study subjects.Children with acute and chronic pancreatitis were excluded.The age, gender, impatient department, imaging exams, discharge outcomes, main diagnosis, diagnostic ICD10 code, and the highest values of serum amylase and lipase during hospitalization were collected through the medical record system.According to the levels of serum amylase and lipase, the children were divided into 3 groups.Patients in group A had normal serum amylase and serum lipase levels.The serum amylase or lipase levels of patients in group B was 1 to 3 times higher than that of group A. The serum amylase or lipase levels in group C was 3 times higher than that of group A. Group B and group C had abnormal pancreatic enzyme levels.According to the prognosis, patients were divided into the survival group and the death group.The relationship of the occurrence of abnormal serum amylase and lipase levels with the age, sex, disease type and prognosis of children was analyzed.Results:The ratio of abnormal trypsin in male and female was 11.5% and 12.9%, respectively.The number of children with abnormal pancreatic enzyme levels in the 28 day -1 year old group, >1-3 years old group, >3-6 years old group, >6 -12 years old group and > 12 year old group were 37 cases (4.6%), 185 cases (15.4%), 199 cases (10.5%), 431 cases (13.9%), and 94 cases (11.7%), respectively.The mortality rate was 1.6% (112/6 867 cases) in group A, 5.2% (32/617 cases) in group B, and 7.6% (25/329 cases) in group C. The mortality risk of group B and C was both higher than that of group A. Compared with group A, the OR (95% CI) of group B and group C was 3.30 (2.21-4.93) and 4.96 (3.17-7.77), respectively.In group C, the top five diseases were parotitis (26.4%), cholangiectasis (11.6%), choledochal cysts (8.5%), gastroenteritis (4.5%) and sepsis (3.3%). Conclusions:Pancreatic enzyme abnormalities in children are associated with adverse prognosis.Pancreatic enzyme abnormalities are more prone to occur in children aged >1-3 with mumps, digestive diseases and congenital digestive system structural deformities.In addition, children with sepsis are also easy to present pancreatic enzyme abnormalities.Clinical attention should be paid to the possibility of secondary pancreatic damage in children with sepsis.
RESUMEN
Objective:To analyze and discuss the application value and teaching effect of simulate patients (SP)-assisted problem-based learning (PBL) combined with team-based learning (TBL) mode in pediatric first aid teaching, in order to provide a new reference for the reform of standardized residency training and teaching mode of pediatrics in the new era in China.Methods:A total of 103 residents who participated in the standardized training in the Department of Pediatrics of Hunan Children's Hospital from January 2018 to December 2020 were selected as the research objects, and they were divided into the control group (50 cases) and the experimental group (53 cases). The control group adopted the previous teaching mode of residents, while the experimental group adopted the SP-assisted PBL combined with TBL mode. In this study, SPSS 22.0 software was used for t test and chi-square test. Results:The examination scores of the experimental group in the theoretical knowledge of pediatric first aid, clinical thinking and skills, and application of pediatric first aid skills were higher than those in the control group [(86.98±3.42), (85.69±5.13), (89.62±4.75)] vs. [(77.23±4.16), (81.16±3.96), (76.54±5.78)], with statistically significant differences between the two groups ( P<0.05). The questionnaire survey showed that the clinical thinking and pediatric emergency skills, doctor-patient communication ability, teamwork ability and other aspects of the experimental group were significantly better than those of the control group ( P<0.05). Conclusion:The SP-assisted PBL combined with TBL mode can produce positive effects in the standardized residency training of pediatrics, which will help residents better master pediatric first aid skills, improve their clinical comprehensive capabilities, and be more conducive to improving the quality of pediatric residency training, which is worth promoting in the new era.
RESUMEN
Objective:To investigate the effect of radioactive 125I seed on angiogenesis of subcutaneously transplanted hepatocellular carcinoma in nude mice and underlying mechanism. Methods:The subcutaneous transplanted tumor model of human hepatocellular carcinoma Huh7 cells was established in nude mice. Twelve nude mice were randomly divided into observation group and control group with 6 mice in each group. The 125I seed with activity of 2.96×10 7Bq was implanted into the transplanted tumor of observation group and another with 0 Bq as control group, respectively. The volume of the transplanted tumor was measured every 4 d and the growth curve of the tumor was recorded. The microvessel density (MVD) of the transplanted tumor was evaluated by immunohistochemical detection of CD31. VEGF-A and HIF-1α protein and mRNA were detected by immunohistochemistry and RT-PCR, respectively. Results:The growth rate of tumor in the observation group was slower than that in the control group, and the difference of tumor volume between two groups at 12 d after 125I seed implantation was significantly different( t=3.167, P<0.05). At 28 d after transplantation, the tumor volumes of control and observation group approached to (963.61 ± 89.56) mm 3and (602.10±75.98) mm 3, respectively. The MVD of the observation group was significantly lower than that of the control group ( t=6.361, P<0.05). The relative expression of VEGF-A and HIF-1α mRNA in the observation group was significantly lower than that in the control group ( t=10.480, 6.414, P<0.05). Protein expression levels of VEGF-A and HIF-1α in the observation group were lower than those in the control group ( t=10.890, 12.250, P<0.05). Conclusions:Radioactive 125I seed can inhibit the growth of HCC xenografts by reducing tumor microvessels, which may be related to the decrease of VEGF-A and HIF-1α expression.
RESUMEN
Objective:To observe the therapeutic effect of echinacoside (ECH) on liver injury and glucose metabolism disorder in sepsis rats induced by cecal ligation and puncture (CLP), and to explore its possible mechanism.Methods:Forty eight male Sprague Dawley (SD) rats were randomly divided into four groups: sham group (sham), model group (CLP), treatment group (CLP+ ECH) and inhibitor group (CLP+ ECH+ EX527). The sham group only received laparotomy, and the model group underwent CLP. The treatment group was intragastric administration of echinacea (30 mg/kg) every day after CLP modeling. The inhibitor group was injected with silence information regulator 1 (SIRT1) inhibitor EX527 (5 mg/kg) one hour before CLP, and then treated the same as the treatment group. Fasting blood glucose, insulin and serum biochemical indexes were detected in virous groups. The serum levels of interleukin (IL)-1 β, IL-6 and tumor necrosis factor-α(TNF-α) were detected by enzyme-linked immunosorbent assay (ELISA). 2′, 7′- dichlorofluorescein diacetate (DCFH-DA) staining was used to observe the production of reactive oxygen species (ROS) in liver tissue of rats in each group; hematoxylin-eosin (HE) staining was used to observe the pathological changes of liver tissue in each group; The expressions of SIRT1, glucose-6-phosphatase (G6Pase), phosphoenolpyruvate carboxykinase (PEPCK), phosphorylated signal transducers and activators of transcription 3 (p-STAT3) and phosphorylated protein ki-nase B(p-AKT) were detected by Western blot.Results:Compared with sham group, the levels of serum glucose, serum insulin, alanine aminotransferase (ALT), aspartate aminotransferase (AST), ROS, IL-1β, IL-6 and TNF-α in model group increased, while the liver glycogen and survival rate decreased (all P<0.05). After echinacoside treatment, the serum glucose, serum insulin, ALT, AST, ROS , IL-1β, IL-6 and TNF-α levels decreased, and the liver glycogen and survival rate increased (all P<0.05); After SIRT1 inhibitor intervention, the levels of serum insulin, ALT, AST, IL-6 and ROS in the inhibitor group increased ( P<0.05). HE staining showed that there were infiltration and necrosis of inflammatory cells in the liver tissue of model group, and echinacoside could significantly reduce the focal and massive necrosis; Western blot showed that compared with the sham group, the expression levels of SIRT1, p-STAT3 and p-AKT protein in the model group decreased, while the expression levels of G6Pase and PEPCK protein increased ( P<0.05); After echinacoside treatment, the expression levels of SIRT1, p-STAT3 and p-AKT increased, while the expression levels of G6Pase and PEPCK decreased ( P<0.05). After SIRT1 inhibitor intervention, the expression of SIRT1, p-STAT3 and p-AKT protein decreased, and the expression of G6Pase and PEPCK protein increased in the inhibitor group ( P<0.05). Conclusions:Echinacoside is a potential therapeutic agent for sepsis associated liver injury and glucose metabolism disorders, which may play a role by targeting SIRT1 to activate STAT3 and AKT in the liver.
RESUMEN
Objective:To assess the value of ultrasonography in the diagnosis of fetal isomerism syndrome in the first trimester.Methods:Sonographic features of 15 fetuses with isomerism syndrome diagnosed in the Maternal and Child Health Hospital of Guangxi Zhuang Autonomous Region from January 2015 to March 2020 were reviewed. Ultrasonic characteristics in the first trimester were analyzed, and the ultrasonic characteristics of early mid-trimester and pathological anatomical results were combined for comparison.Results:There were 6 cases of left isomerism syndrome (LIS) and 9 cases of right isomerism syndrome (RIS) in the 15 fetues.Increased nuchal translucency(NT) (≥3.0 mm, 6 cases), reversed A wave in ductus venosus (10 cases), and atrio-ventricular valve regurgitation (14 cases) were found during the first trimester. There were 14 cases with abnormal visceral laterality. Of the 15 fetues, 14 cases with cardiac malformations, including 6 cases of functional single ventricle, 8 cases of complete atrioventricular septal defect (CAVSD), and 12 cases with great artery abnormalities. All of the 6 LIS cases had bradycardia, 3 cases had interruption of inferior vena cava (IVC). Six cases of RIS had juxtaposition of descending aorta and IVC, and 1 case of RIS had total anomalous pulmonary vein drainage. The major structural malformations were consistent with the early mid-trimester ultrasound examination or autopsy. Karyotype and chromosomal microarray were available in 12 cases and all were normal.Conclusions:Isomerism syndrome has high positive rate of fetal aneuploidies ultrasonographic marker, especially with the atrio-ventricular valve regurgitation, but the risk of chromosome abnormality is low. Ultrasound screening for fetal cardiac structural abnormalities is beneficial to the early diagnosis of isomerism syndrom in the first trimester.
RESUMEN
Objective:To explore the feasibility and prognosis of prenatal ultrasonic diagnosis of fetal isolated vascular ring at 11-13 + 6 weeks. Methods:A total of 36 996 fetuses were selected to compare the results of ultrasound screening at 11-13 + 6 weeks and 20-24 weeks of pregnancy in Guangxi Maternity & Child Healthcare Hospital from January 2016 to January 2020, the reasons for missed diagnosis and misdiagnosis of fetal isolated vascular ring by ultrasonography in the first trimester were summarized. Results:Thirty-five cases were diagnosed as isolated vascular ring in the first trimester, including 19 cases right aortic arch combined with aberrant left subclavian artery with "U-shaped" vascular ring, 7 cases double aortic arch with "O-shaped" vascular ring, and 9 cases aberrant right subclavian artery with "C-shaped" vascular ring. While 155 cases were diagnosed as isolated vascular ring at 20-24 weeks of pregnancy, consisting of 18 cases of combined with aberrant left subclavian artery, 9 cases of double aortic arch, 126 cases of aberrant right subclavian artery and 2 cases of pulmonary artery sling, the diagnosis coincidence rates were 94.74%, 77.78%, 7.14%, 0(Kappa value were 0.97, 0.88, 0.13, 0). For the diagnosis of right aortic arch combined with aberrant left subclavian artery, double aortic arch and aberrant right subclavian artery in the first trimester, the specificities were 99.99%, 100%, 100%, the sensitivities were 100%, 77.78%, 7.14%, the false-positive rates were 0.01%, 0, 0, the false-negative rates were 0, 22.22%, 92.86%, and the Youden′s indices were 0.99, 0.78, 0.07.Conclusions:Right aortic arch combined with aberrant left subclavian artery and double aortic arch have high coincidence rate by ultrasonography in the first trimester, while the diagnostic coincidence rate of isolated aberrant right subclavian artery was low. Ultrasound screening for isolated vascular ring in the first trimester still needs ultrasound examination in the second trimester to exclude the minor cardiac malformations that are difficult to diagnose in the first trimester.
RESUMEN
Objective:To investigate whether miRNA-296-5p can inhibit enterovirus 71 (EV71) virus replication in neural cells SK-N-SH by targeting the phosphatase and tensin homology deleted on chromosome 10 (PTEN)/phosphatidylinositol 3-kinase (PI3K)/serine/threonine kinases (AKT) signaling pathway.Methods:Serum samples were collected from patients with EV71 virus-infected hand-foot-mouth disease and normal physical examination, and the expressions of serum inflammatory factors procalcitonin (PCT), C-reactive protein (CRP), tumor necrosis factor-α (TNF-α) , interleukin-6 (IL-6), IL-1β, and IL-13 were detected by enzymelinked immunosorbent assay (ELISA). Human neuroblastoma SK-N-SH cells infected by EV71 virus in logarithmic growth phase were set up as control group, miRNA-296-5p mimic group and miRNA-296-5p inhibitor group. The transfection was carried out according to the Lipofectamine 2000tm cell transfection reagent. The expression of EV71-VP1 gene mRNA and protein and PTEN/PI3K/Akt signal pathway related molecules in three groups of cells was observed by real-time fluorescent quantitative polymerase chain reaction (qRT-PCR) and Western blot.Results:ELISA test results showed that the levels of serum inflammatory factors PCT, CRP, TNF-α, IL-1β, IL-6 and IL-13 in patients with EV71 virus-infected hand, foot and mouth disease were significantly higher than those in normal physical examination ( P<0.05). The results of qRT-PCR and Western blot showed that the mRNA and protein levels of mirna-296-5p and PTEN in SK-N-SH were significantly decreased after EV71 virus infection, while the mRNA and protein levels of EV71-VP1 and molecules related to PI3K/AKT signaling pathway were significantly increased ( P<0.05). The expression of PTEN was significantly increased in the miRNA-296-5p mimic group, and the expression of EV71-VP1 and the activation of the PI3K/AKT signaling pathway were inhibited, while the effect was reversed in the miRNA-296-5p inhibitor group ( P<0.05). Conclusions:MiRNA-296-5p inhibits the replication of EV71 virus in neural cells SK-N-SH by targeting the PTEN/PI3K/AKT signaling pathway, while reducing the cellular inflammatory response, targeting miRNA-296-5p and downstream PTEN/PI3K/AKT The signal pathway is expected to provide therapeutic targets and theoretical basis for the treatment of hand-foot-mouth disease caused by clinical EV71 virus.

RESUMEN
Objective: To investigate the application of single-molecule PCR (SM-PCR) in the detection of plasma ctDNA for the treat-ment of patients with advanced lung adenocarcinoma. Methods: In total, 30 patients diagnosed with advanced lung adenocarcinoma were enrolled between June 2017 and May 2018. ctDNA fragments of the target genes (EGFR, KRAS, BRAF, ALK, HER2, and TP53) from the blood samples were enriched by SM-PCR, and DNA libraries were prepared. Finally, a high-throughput sequencing was performed. The EGFR detection of tumor tissue samples was performed using real-time fluorescence PCR based on the amplification refractory mutation system (ARMS) and consistency in the results of EGFR mutation detection in the plasma and tissue was compared. Results:The results of both the methods were consistent (Kappa=0.867, P<0.001). The McNemar's test also indicated that the results are not statistically different (P=0.500). Conclusions: SM-PCR can be used for the detection of plasma EGFR mutations. The target detection sites are more comprehensive and multiple mutations can be detected at the same time. Results of the analysis are more precise and can be absolutely quantified.

Objective To analyze the clinical features of critically ill children with abnormal pancreatic ultrasound findings in order to explore the related risk factors for offering evidence-based diagnosis of pancreatic damage secondary to critical illness.Methods A prospective study was performed in 531 critically ill children admitted to pediatric intensive care unit(PICU) of 17 children' hospitals from January 2012 to March 2014.All patients were divided into control group(513 cases) and abnormal group(18 cases) according to the pancreatic ultrasound findings.Comparison of clinical features and biochemical indicators were made between two groups.The related risk factors associated with abnormal pancreatic ultrasound findings were analyzed by using Logistic regression analysis.ROC curves were used to evaluate the role of amylase and lipase in the diagnose of abnormal pancreatic ultrasound findings.Results The incidence of abnormal pancreatic ultrasound findings in critically ill children was 3.39%, the average age of abnormal group was significantly older than that in control group (P<0.01).There were not statistically significant differences in gender and primary disease between two groups.The incidence of hypotension was 22.2% and the incidence of abdominal muscle tension was 16.7% in abnormal group,which were statistically higher than those in control group (P<0.05).The levels of calcium, albumin of abnormal group were significantly lower than those in control group (P<0.01), and levels of serum amylase, lipase, lactate dehydrogenase in abnormal group were significantly higher than those in control group (P<0.01).The risk factors associated with abnormal pancreatic ultrasound findings were age, blood pressure, calcium,amylase.Area under the ROC curve of abnormal pancreatic ultrasound findings determined by amylase and lipase were 0.803 and 0.745,respectively (P<0.05).The sensitivity was 0.667, specificity was 0.881 when the serum amylase was 101.5 U/L, the sensitivity was 0.722, specificity was 0.928 when the serum lipase was 96.9 U/L.Conclusions The incidence of abnormal pancreatic ultrasound findings was rather low in critically ill children.The risk factors associated with abnormal pancreatic ultrasound findings were hypotension, hypocalcemia, and hyperamylasemia.The elevated serum amylase and lipase might be the most likely factors associtaed with abnormal pancreatic ultrasound findings.
RESUMEN
BACKGROUND:In the treatment of primary knee osteoarthritis, total knee arthroplasty is a common treatment, but there are some shortcomings in the traditional operation, which maylead to early failure of the prosthesis. OBJECTIVE:To explore the difference of computer-assisted total knee arthroplasty by vastus medialis approach from the traditional total knee arthroplasty. METHODS:A total of 79 patients with primary knee osteoarthritis were randomly divided into control group (41 cases) and observation group (38 cases), which underwent conventional total knee arthroplasty and computer-assisted total knee arthroplasty by vastus medialis approach. Surgical incision, operation time, total blood loss and drainage volume were recorded and compared in both groups. In 12 months of folow-up, Hospital for Special Surgery knee score was evaluated, and the complications were recorded and compared between the two groups. RESULTS AND CONCLUSION:(1) Operative incision was significantly less in the observation group than in the control group. Operation time was significantly shorter in the observation group than in the control group. Total blood loss and drainage volume were significantly lessin the observation group than in the control group (alP< 0.05). (2) Patients in both groups were folowed up for 12 months. Index score and total score of knee function were significantly higher in the observation group than in the control group (al P< 0.05). (3) No adverse events such as infection, prosthesis loosening or fracture appeared in the observation group. In the control group, four cases affected prosthesis loosening. One case suffered from wound infection. Above events were improved obviously after active treatment. No serious complications occurred. The incidence of complications was significantly lower in the observation group than in the control group (P< 0.05). (4) The results show that, compared with the traditional operation, the choice of the femoral medial approach and the use of computer aided design technology can simulate the knee replacement process, set the cutting position, improve the accuracy and success rate of surgery, have less trauma, and effectively improve knee function, and reduce the incidence of postoperative complications.
