ABSTRACT

OBJECTIVE@#To investigate the effectiveness of arthroscopic multi-point fixation with anchor and suture in the treatment of tibial insertion avulsion fracture of anterior cruciate ligament (ACL) involving the anterior root of lateral meniscus (LM).@*METHODS@#A retrospective analysis was conducted on the clinical data of 28 patients with tibial insertion avulsion fracture of ACL involving the anterior root of LM who were treated with arthroscopic multi-point fixation with anchor and suture between October 2017 and January 2023. There were 12 males and 16 females with the mean age of 26 years (range, 13-57 years). There were 20 cases of sports injury and 8 cases of traffic accident injury. In 2 cases of old fracture, the time from injury to operation was 45 days and 90 days, respectively; in 26 cases of fresh fracture, the time from injury to operation was 3-20 days (mean, 6.7 days). According to the Meyers-McKeever classification, there were 4 cases of type Ⅱ, 11 cases of type Ⅲ, and 13 cases of type Ⅳ. The preoperative Lysholm knee function score was 42.1±9.0, the International Knee Documentation Committee (IKDC) score was 40.0±7.3, and the Tegner score was 0.7±0.7.@*RESULTS@#All operations were successfully completed, and the incisions healed by first intention. All the 28 patients were followed up 5-60 months (mean, 20.4 months). During the follow-up, there was nocomplication such as infection, vascular or nerve injury, loosening or breakage of internal fixator, or stiffness of knee joint. Postoperative X-ray films showed satisfactory fracture reduction and firm fixation. All fractures healed clinically, and the healing time was 8-16 weeks (mean, 10.3 weeks). At last follow-up, Lachman test and anterior drawer test were negative. At last follow-up, Lysholm knee function score was 92.4±5.5, IKDC score was 91.6±4.4, and Tegner score was 5.2±1.1, which significantly improved when compared with preoperative scores ( t=-22.899, P<0.001; t=-29.870, P<0.001; t=-19.979, P<0.001).@*CONCLUSION@#Multi-point fixation with anchor and suture in the treatment of tibial insertion avulsion fracture of ACL involving the anterior root of LM can not only fix the LM, but also effectively reduce and fix the avulsion fracture, which can obtain good effectiveness.

ABSTRACT

OBJECTIVE@#To explore the genetic basis for a child with Hemoglobin Santa Ana (Hb Santa Ana).@*METHODS@#The child was admitted to the Children's Hospital of Chongqing Medical University on August 4, 2013 due to anemia, splenomegaly and deepening urine color for 5 years. His clinical data were collected. Peripheral blood samples of the child and his parents were collected for routine blood test. The erythrocyte parameters of the child and his parents were determined with an automatic hemocyte analyzer. The hemoglobin components of the child and his parents were detected by high-performance liquid chromatography (HPLC). Common mutations associated with thalassemia were detected by Gap-PCR and PCR-reverse dot blotting (PCR-RDB). Rare variants of the globin genes were detected by next generation sequencing (NGS), and the result was verified by Sanger sequencing.@*RESULTS@#The child has shown mild to moderate hemolytic anemia. Routine blood test showed that he had lower hemoglobin (90 g/L) and mean corpuscular hemoglobin concentration (267 g/L) but a higher reticulocyte ratio (0.141), which indicated hypopigmented hyperplastic anemia. Analysis of hemoglobin component showed that his hemoglobin F was elevated to 10.7%, which indicated abnormal synthesis of β globin peptide chain. HPLC analysis showed an abnormal peak accounting for 4.5% of the total area. Neither of his parents was found to have abnormal results for routine blood test and hemoglobin component analysis. No common globin gene variant was detected in the child. Gene sequencing revealed that the child has harbored a heterozygous variant of HBB: c.266T>C, which was de novo in origin. Based on the guidelines of American College of Medical Genetics and Genomics, the variant was predicted to be pathogenic.@*CONCLUSION@#The heterozygous HBB: c.266T>C variant probably underlay the hemolytic anemia associated with Hb Santa Ana in this patient.

ABSTRACT

OBJECTIVE@#To investigate the repair method of type Ⅱc injury in the lateral meniscus popliteal tendon area based on the porcine knee joint.@*METHODS@#Eighteen commercially available fresh porcine knee joints were randomly divided into 3 groups ( n=6). After preparing a type Ⅱc injury in the lateral meniscus popliteal tendon area, and the anterior (group A), posterior (group B), or anterior and posterior (group C) of the popliteal hiatus (PH) was sutured by vertical mattress. The tension meter was used to apply gradient tensions of 2, 4, 6, 8, and 10 N along the tibial plateau horizontally, respectively, to pull the midpoint of the lateral meniscus popliteal tendon area. The displacement values before modeling, after modeling, and after suture were recorded. The reduction value of lateral meniscus displacement and reduction rate after suture were calculated and compared between groups.@*RESULTS@#There was no significant difference between groups ( P>0.05) in the displacement values before modeling, after modeling, and after suture under different tensions. There was no significant difference between groups A and C ( P>0.05) in the reduction value of lateral meniscus displacement and reduction rate after suture under different tensions. The reduction value of lateral meniscus displacement and reduction rate after suture in group B were lower than those in groups A and C. The reduction value of lateral meniscus displacement under tension of 2 N and the reduction rates under tensions of 2, 4, and 6 N between groups A and B showed significant differences ( P<0.05). The reduction value of lateral meniscus displacement and the reduction rate under tensions of 2, 4, and 6 N between groups B and C showed significant differences ( P<0.05).@*CONCLUSION@#Suturing the anterior area of PH is the key to repairing type Ⅱc injury of lateral meniscus popliteal tendon area.

ABSTRACT

Objective:To improve the understanding of autoimmune lymphoproliferative syndrome (ALPS).Methods:The clinical data of the proband and his family members in Children's Hospital Affiliated to Zhengzhou University in August 2018 were retrospectively analyzed, and the peripheral blood DNA of the proband, his parents and siblings was extracted. High-throughput next-generation sequencing was used to make gene analysis and validation. Phenotype and genotype of them were also analyzed. Relevant literature was reviewed.Results:The proband was a 1-year and 1-month old boy with hemolytic anemia, thrombocytopenia and splenomegaly as the main manifestations. The double negative T cells and the Vitamin B 12 of the proband were significantly increased and the autoantibodies were positive. The boy's father had a history of splenomegaly. His elder brother and sister had similar clinical manifestations. The results of next-generation sequencing showed that the FAS gene frameshift mutation (c.648delT) was detected in this boy and his father, elder brother and sister, which was a new mutation. After immunosuppressive treatment, the symptoms of the boy improved and the blood cells increased. Conclusions:The frameshift mutation of FAS gene may be the cause of the disease in this ALPS pedigree. Clinically, it is necessary to consider ALPS for children with unexplained hemocytopenia and hepatosplenomegaly. Double-negative T cells, autoantibodies, Vitamin B 12 should be tested, and high-throughput gene sequencing should be performed if necessary.

ABSTRACT

Objective:To analyze the clinical phenotypes and molecular genetic characteristics of hereditary spherocytosis (HS) in children.Methods:The clinical data of children with HS in the Affiliated Children′s Hospital of Zhengzhou University from June 2014 to June 2018 were collected and analyzed retrospectively.The peripheral blood samples of 20 children and their parents were collected and targeted capture or whole exon group sequencing was performed using the second generation sequencing technique, and the suspicious mutation sites were verified by Sanger sequencing.Results:A total of 43 pediatric patients (23 males, 20 female) were included in this study.The median age of onset of 1 year old and 11 months (1 month to 10 years old). Pallor (27/43 cases, 62.79%) was the main symptom.Typical clinical manifestations were anemia (36/43 cases, 83.72%), jaundice (35/43 cases, 81.40%), splenomegaly (33/43 cases, 76.74%), and hepatomegaly (27/43 cases, 62.79%). The proportion of spherical erythrocytes in peripheral blood of 23 cases (23/43 cases, 53.49%)≥ 0.1, and the proportion of spherical erythrocytes in bone marrow smears of 17 cases (39.53%) was ≥ 0.1, and 20 cases were positive in erythrocyte osmotic fragility test (20/43 cases, 46.51%). Comparison of 29 children before and after blood transfusion: post-transfusion hemoglobin (Hb) [(88.69±11.22) g/L vs. (78.24±14.47) g/L], mean corpuscular volume (MCV) [(89.37±7.15) fL vs.(84.08±7.49) fL], mean corpuscular hemoglobin (MCH) [(29.12±2.70) pg vs.(27.36±1.95) pg], mean corpuscular hemoglobin corpuscular (MCHC) [(361.79±32.27) g/L vs.(356.31±31.43 ) g/L] were increased, and the total bilirubin (TB) level was lower after blood transfusion than before blood transfusion [(33.27±16.42) μmol/L vs.(41.58±15.40) μmol/L], the differences were statistically significant ( t=-3.538, -5.187, -5.412, -7.404, 2.527, all P<0.05). Seven children underwent splenectomy: postoperative Hb[(116.00±5.54) g/L vs.(75.71±9.96) g/L], MCH[(29.87±1.62) pg vs.(24.61±1.65) pg], MCHC [(391.14±12.99) g/L vs.(315.14±51.99) g/L] all increased, the difference was statistically significant ( t=-9.234, -4.330, -4.031, all P<0.05). The Hb in the operation group was significantly higher than that in the blood transfusion group, including the treatment effect of operation was more significant ( t=-9.247, P<0.05). Thirteen pathogenic mutations (11 new mutations not reported) were detected in 3 genes ( ANK1, SPTB and SPTA1) in 13 children, 8 of who were mutations in ANK1, 4 cases of which were mutations in SPTB and 1 case of which was mutation in SPTA1.Among the 13 mutations, 12 cases were de novo except one inherited from the mother. Conclusions:Anemia and pallor are the initial symptoms of HS in children.Blood transfusion can temporarily improve the symptoms of anemia and jaundice.Splenectomy is an effective and fundamental treatment.The gene diagnosis of 13 pediatric patients got gene diagnosis, which provided basis for genetic consultation of the next fetus.Eleven new mutations were found in ANK1, SPTB, SPTA1 genes, which exten-ded the gene mutation spectrum of HS.

ABSTRACT

Objective@#To explore the relationship between serum C1q and tumor necrosis factor related protein 6(CTRP6) level and insulin resistance in patients with newly diagnosed type 2 diabetes mellitus (T2DM).@*Methods@#A total of 167 patients with newly diagnosed T2DM in the outpatient department of our hospital were recruited from April 2016 to March 2017 and 165 subjects with normal glucose tolerance were used as the control group. The concentrations of CTRP6, interleukin 6 (IL-6), monocyte chemoattractant protein-1 (MCP-1), and tumor necrosis factor α (TNF-α) were determined by ELISA.@*Results@#Circulating CTRP6 level was significantly higher in T2DM group than that in control group [(652.54±132.57) vs (521.28±119.93)μg/L, P<0.01] after adjusting age and body mass index (BMI). Overweight/obese subjects revealed higher CTRP6 levels compared with those in lean individuals. In addition, circulating CTRP6 level was positively correlated with BMI, waist circumference, fasting plasma glucose, postprandial 2h plasma glucose, HbA1C, fasting insulin, homeostasis model assessment insulin resistance index (HOMA-IR), triglyceride (TG), IL-6, MCP-1, highly sensitive C-reactive protein (hs-CRP), and TNF-α, while it was inversely correlated with high-density lipoprotein-cholesterol(P<0.01). Multivariate linear regression analysis showed that TG, HOMA-IR, and IL-6 were independent factors for CTRP6 level. After adjusting for potential confounders, CTRP6 remained an independent risk factor for T2DM. Trend test showed that the increase in CTRP6 level was significantly linear with the occurrence of T2DM. The analysis of receiver operating characteristic curves revealed that the area under the curve for circulating CTRP6 to predict T2DM was 0.730.@*Conclusions@#CTRP6 may be associated with insulin resistance.

ABSTRACT

Objective To investigate the effect of miR-21 on the secretion of IFN-γ and IL-17 from peripheral blood mononuclear cells (PBMC) in type 1 diabetic patients (T1D). Methods The expression levels of miR-21 in PBMC from 60 T1D patients and controls by quantitative real-time quantitative polymerase chain reaction (qRT-PCR) were detected and the secretions of IFN-γ and IL-17 from T1D PBMC after transfection with miR-21 were detected by enzyme linked immunosorbent assay. Results The expression of miR-21 in PBMC from T1D patients was significantly lower than the control (P<0.01). The levels of IFN-γand IL-17 from T1D PBMC after transfection with miR-21 were remarkably downregulated compared to the control (P < 0.05 or P < 0.01). Conclusion Compared with that at the healthy control group, the expression of miR-21 in PBMC from T1D patients is decreased. MiR-21 could suppress the secretions of IFN-γand IL-17 from PBMC in T1D patients.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the expression level and analyze the clinical significance of NT5C2, which is an nucleoside analogues metabolism related gene, in children with acute leukemia (AL).</p><p><b>METHODS</b>Real-time PCR and immunohistochemistry were presented to detect the level of NT5C2 mRNA and its protein product cN- Ⅱ in bone marrow samples of 63 patients initially diagnosed with AL, 15 patients who achieved complete remission, 7 patients who relapsed and 16 non- hematologic malignancie controls. The expression of NT5C2 mRNA in different groups of AL and its relevance with clinical indicators were analyzed.</p><p><b>RESULTS</b>①The expression of NT5C2 mRNA in newly diagnosed B-ALL, TALL, AML and controls were 1.16 (0.89-2.25, 0.96 (0.74-1.25, 1.66 (0.84-3.15) and 0.88 (0.61-1.21), respectively. NT5C2 mRNA expression in AML (P<0.01) and B-ALL (P<0.05) cases were higher than that in controls; NT5C2 mRNA expression in T- ALL and in controls showed no significant difference (P>0.05). Changes of NT5C2 mRNA level were observed between preliminary diagnosis and complete remission in 15 patients. NT5C2 mRNA levels were significantly decreased in complete remission stage than that in newly diagnosis AL (P<0.01). NT5C2 mRNA levels of relapsed-refractory group were higher than that of complete remission group and controls (P<0.01). ② Immunohistochemical staining results revealed that NT5C2 protein levels were consistent with the trend of mRNA levels. ③NT5C2 mRNA levels in AML (r=0.434) and T-ALL (r=0.389) were positively correlated with risk classification (P<0.05). ④ During chemotherapy of patients with AML, the NR rate of bone marrow in NT5C2 high expression group was higher than that of low expression group after 9 days induction chemotherapy (35.2% vs 0) and before consolidation therapy (25.0% vs 0); The positive rate of minimal-residual disease (36.4% vs 14.3%) and relapse rate of AL (38.5% vs 28.6%) were increased in NT5C2 high expressed patients than that in low expressed patients, but all the differences were insignificant (P>0.05).</p><p><b>CONCLUSION</b>High expression of NT5C2 was found to be a related risk factor of AL children with unfavourable prognosis. NT5C2 promises a new target for guiding individualized chemotherapy and evaluating the prognosis of childhood acute leukemia and monitoring recurrence.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To establish a hemophagocytic lymphohistiocytosis (HLH)-like mouse model induced by CpG oligodeoxynucleotide (CpG-ODN1826) and interferon (IFN)-γ for further study on therapy.</p><p><b>METHODS</b>Wild type adult C57BL/6 mice were administered with PBS or CpG-ODN1826 (50 μg) by intraperitoneal injection every two day and IFN-γ subcutaneous injection every day. Parameters of HLH were evaluated on day 10.</p><p><b>RESULTS</b>As compared to control, HLH-like symptoms in CpG group were characterized with pancytopenia accompanied by increased ratios of monocytes, alanine aminotransferase [(198.7±54.2)IU/L], triglyceride level [(12.1±0.6)g/L], and serum ferritin [(708.4±11.8)pmol/L]; decreased albumin [(217.7±4.3)g/L], fibrinogen [(17.1±1.9)g/L] (all P<0.05). Hepatosplenomegaly was obvious in CpG group. The liver in CpG group had multifocal hepatocytes necrosis and perivascular inflammations. Spleen had expanding red pulp and hyperplastic nucleated cells. Furthermore, macrophages in the liver and spleen were largely activated. Hemophagocytosis were observed in liver, spleen and bone marrow smear. The CpG group was alive during experiment, other than significant decreased activity after the first injection of CpG-ODN.</p><p><b>CONCLUSION</b>These data demonstrate that repeated administration of CpG-ODN1826 and IFN-γ could induce HLH-like symptoms without fatal condition in wild type C57B/L mice. This protocol could establish a mild HLH-like mouse model, which could be useful for further study on HLH.</p>

ABSTRACT

Objective:To investigate the expression of sal-like 4 (SALL4) gene in children with acute leukemia and analyze its clinical significance. Methods:Real-time PCR and immunohistochemistry were used to detect SALL4 mRNA and SALL4 protein ex-pressions in 50 patients initially diagnosed with acute leukemia and in 15 patients with immune thrombocytopenic purpura (ITP), which served as controls. Changes were detected in SALL4 mRNA expression from preliminary diagnosis and after complete remission of 5 acute leukemia patients. The relationship between SALL4 mRNA expression and clinical indicators was analyzed. Results: SALL4 mRNA expression is higher in initially diagnosed B-ALL [13.89 (1.00-63.15)] and AML [11.12 (2.31-56.59)] than in ITP controls [1.00 (0.29-1.71)] (P0.05). SALL4 protein expression is in agreement with SALL4 mRNA expression. SALL4 mRNA expression significant-ly decreased in complete remission stage [0.98 (0.22-1.09)] than in acute phase [28.64 (11.20-87.46)] in acute-leukemia patients (P0.05). Conclusion:SALL4 was found to play an important role in pro-moting childhood B-ALL and AML, which promises a new target for monitoring the therapeutic effects and evaluating the prognosis of childhood B-ALL and AML.

ABSTRACT

Objective To dynamic monitor and analyze the characteristic of polysomnography (PSG)and melatonin levels of delirium patients in intensive care unit (ICU). Methods A prospective observational study was performed from December 2013 to April 2014. The patients admitted to ICU of Affiliated Hospital of Binzhou Medical College for more than 72 hours were evaluated with confusion assessment method for the ICU (CAM-ICU),and were divided into delirium group and non-delirium group. Sleep patterns of all the patients underwent continuous PSG for up to 24 hours were evaluated. Melatonin levels were determined every 4 hours with enzyme linked immunosorbent assay (ELISA)duration sleep monitoring. Results Eighteen patients were enrolled,and 9 were delirium patients. All the patients had sleep disorders:a decrease in rapid eye movement (REM)sleep 〔(5.91±5.26)%〕,an increase in the sleep fragmentations 〔arousal index was (15.40 ±12.79)times/h〕,and the N3 sleep stage was on the lower limit of normal 〔(14.67 ±11.10)%〕. Compared with non-delirium group,the REM sleep was significantly decreased in delirium group〔(0.10±0.20)%vs.(8.83±3.81)%,t=4.782,P=0.001〕. Melatonin levels lost rhythm between day and night,and there was no difference in melatonin between delirium group and non-delirium group (time effect:F=1.370,P=0.287;between-group effect:F=1.646,P=0.250;interaction effect:F=1.558,P=0.247). The peak of melatonin levels of delirium group appeared on 06:00 〔(137.84±62.21)ng/L〕and 14:00 〔(148.24±58.8)ng/L〕, the minimum value on 22:00 〔(64.47 ±26.97) ng/L〕. But in non-delirium group,the peak of melatonin levels appeared on 02:00 〔(63.52 ±39.75)ng/L〕,the minimum value on 10:00 〔(44.87 ±11.19)ng/L〕. Conclusions ICU patients have sleep disorders,and the delirium patients have less REM stage. Normal rhythmic melatonin secretion changes of ICU patients were lost. The delirium peak of patients appears in the daytime.

ABSTRACT

Objective To investigate the clinical effect of rhG-CSF combined transplantation of autologous bone marrow mesenchymal stem cells on cerebral infarction. Methods 42 acute cerebral infarction patients were randomly divided into tow groups: Injection rhGCSF combined autologous bone marrow mesenchymal stem cells group(treatment group, n=20)and conventionality therapy group(control group, n=22).The efficacy was assessed by National Institutes of Health Stroke Scale(NIHSS), Barthel Index(BI)and diffusion-weighted imaging(DWI),perfusion-weighted imaging(PWI)at baseline and the 3rd month after treatment. Result The scores of NHISS and BI treatment group were 4.8±2.0 and 78.5±7.2 respectively. while were 7.2±2.4 and 56.1±6.3 in control group at the 3rd month after treatment. The difference were significant(P<0.01).PWI in treatment group Was higher than that in control group. There was no significant side-effect in treatment group. Conclusion rHG-CSF combined autologous bone marrow mesenchymal stem cells is a safe, efficient treatment for acute cerebral infarction patients, which is a better way than conventionality therapy.

ABSTRACT

Objective:To explore the mechanism of islet cell apoptosis caused by glucose at different concentrations.Methods:The islet cells of SD adult rats were prepared by collagenase digestion,purified by Fcoll400 and cultured in RPMI1640.Different concentrations of glucose or mannitol were added into the monolayer of islet cells.The medium insulin concentration was measured by RIA.The apoptosis rate was measured by the flow cytometry and the bax and bcl-2 expressions were detected by immunoblot.Results:①With glucose concentration raised from 11.1 mmol/L to 22.2 mmol/L,the insulin concentration began to raise and reached the peak,then it began to decline.②With glucose at 11.1 mmol/L and 22.2 mmol/L,the apoptosis rate was the highest,while at 5.5 mmol/L,there was no significant difference compared with the controls. For the groups of mannitol-infused,there was no differences of bax or bcl-2 expressions and no difference of the apoptosis rate comparing with the controls.③With glucose infused,the bcl-2 expressions in 11.1 mmol/L and 22.2 mmol/L groups were negative,bax expression was positive;the bax and bcl-2 expressions were negative in the group of 33.3 mmol/L;the bax and bcl-2 expressions in the 5.5 mmol/L group showed no difference compared with the controls.Conclusion:Higher levels of glucose at 11.1mmol/L and 22.2 mmol/L lead to the release of more insulin and the raise of apoptosis rate.But with glucose concentration at 33.3 mmol/L,the release of insulin decreased and the apoptosis rate declined.Hyperosmolality could not cause the apoptosis of the islet cell.

ABSTRACT

Objective To observe the effects of aminoguanidine and Vitamin C on lipid of streptozotocin-induced didbetic rats.Methods Diabetic nephropathy rats were induced by intraperitoneal injection of streptozotocin.Fifty Sprague-Dawley(SD) rats were randomly divided into normal control group,model group,Vitamin C group,aminoguanidine group and Vitamin C associated with aminoguanidine group.All the rats were treated for 16 weeks.During and after the treatment,the general state of the rats was observed and the levels of blood sugar,triglyceride,total cholesterol,low density lipoprotein,high density lipoprotein,glycosylated hemoglobin,and glycated low density lipoprotein in different groups were detected.Results The rats in the four groups suffered diabetes mellitus and renal function lesion.Aminoguanidine and Vitamin C could improve the general state of the rats,but had no effect on the blood sugar.Vitamin C could decrease the levels of triglyceride,serum cholesterol,low density lipoprotein,glycosylated hemoglobin,and glycated low density lipoprotein,and increase the level of high density lipoprotein.There was a synergistic effect with the combination of the two drugs. Conclusion Aminoguanidine and Vitamin C have no effect in the decrease of blood sugar level but have a certain effect on regulating blood lipid.There is a synergistic effect with the combination of the two drugs.
