Effect of VIT1/VIT2 overexpression on Fe and Cd accumulation in rice endosperm / 生物工程学报

Iron (Fe) deficiency and excess cadmium (Cd) in rice grain are important problems to be solved in agricultural production. Previous studies have shown that OsVIT1 and OsVIT2 are vacuolar iron transporters. In this study, wild-type ZH11 was selected as the background material and OsVIT1 and OsVIT2 were overexpressed in endosperm by using endosperm specific promoter Glb-1. Field experiments were conducted to study the effect of OsVIT1 and OsVIT2 overexpression on Fe and Cd accumulation in different parts of rice. The results showed that OsVIT1 overexpression in endosperm significantly reduced Fe content in grain by about 50%, while significantly increased zinc (Zn) and copper (Cu) contents in straw and Cu content in grain. OsVIT2 overexpression in endosperm significantly decreased Fe and Cd contents in grain by about 50%, and significantly increased Fe content in straw by 45%-120%. Overexpression of OsVIT1 and OsVIT2 in endosperm did not affect the agronomic traits of rice. In conclusion, OsVIT1 and OsVIT2 overexpression in endosperm reduced Fe accumulation in rice grain, which did not achieve the expected effect. OsVIT2 overexpression in endosperm also decreased Cd accumulation in grain and increased Fe accumulation in straw, which provided reference for iron biofortification and cadmium reduction in rice.

Effect and necessity of early surgical management of neonatal testicular torsion: an analysis of 11 cases / 中华围产医学杂志

Objective:To investigate the clinical features of neonatal testicular torsion and to evaluate the effect and necessity of early intervention.Methods:A retrospective analysis was performed on 11 neonates admitted to the Second Hospital of Shandong University with neonatal testicular torsion from June 2017 to June 2022. Clinical data of these cases including clinical manifestations, ultrasonography findings, surgical management and outcomes were reviewed and analyzed with descriptive statistical methods.Results:The median age of the 11 patients on admission was 2.6 d (1-5 d). The median time from finding abnormal scrotum to admission was 12 h (1-120 h). Various degrees of scrotal swelling or scleroma were found in the patients. Among them, seven patients presented with acute inflammatory signs of cyano sis or skin redness, and testis-like tissue induration could be touched. Ultrasound scan showed abnormal blood flow in the affected testicle in all cases. Emergency scrotal exploration under general anesthesia was performed successfully in all cases and ten of them underwent orchiectomy of the affected testicle plus contralateral orchiopexy. The rest one who was admitted within 1 h after birth only underwent orchiopexy of the affected testicle as the parents refused contralateral testicular exploration. During the operation, 12 twisted testis were observed, including seven with extravaginal torsion, three with intravaginal torsion and two adhering to the surrounding tissue without normal testicular tissue or distinguishable torsion direction or degree. In this study, ten patients had unilateral testicular torsion, which affected the left side in seven cases and the right side in three cases, and one had bilateral testicular torsion, which was diagnosed as left testicle torsion before surgery. During scrotal exploration, the left testicle of this bilateral case was resected due to necrosis, while the right testicle twisted about 180 degrees with good blood flow and was subjected to orchidopexy after reduction. In one case, the unaffected testicle was unfixed and dysplastic during contralateral exploration, which was also subjected to orchidopexy. In the 12 testis with torsion, one testicle of the patient admitted within 1 h after birth and the right testicle of the bilateral case were preserved with a salvage rate of 2/12. Pathological examination showed necrosis in the ten excised testis, and fibrosis and calcification foci in two of them. None of the patients had any perioperative complications and the scrotal incision healed well in all neonates. The patients were followed up for 6-12 months with regular ultrasound. The two preserved testis and the contralateral testis subjected to orchidopexy were located in the scrotum with good blood supply, and no torsion, atrophy or other abnormalities occurred.Conclusions:Neonatal testicular torsion is rarely seen in clinical practice and has no specific manifestations. It has a high excision rate due to testicular necrosis. Early diagnosis and bilateral scrotal exploration are crucial to the prognosis and the keys to save the affected testis and avoid anorchidism.

Comparison of efficacy and safety of biologics versus methotrexate in the treatment of severe pediatric plaque psoriasis / 中华皮肤科杂志

Objective:To compare the efficacy and safety of biologics versus methotrexate in the treatment of severe pediatric plaque psoriasis.Methods:A retrospective matched case-control study was carried out. Twenty children with severe plaque psoriasis from Beijing Children′s Hospital, Capital Medical University from June 2016 to November 2021 were included in this study, and the patients treated with biologics (adalimumab or secukinumab) were matched with those treated with methotrexate at a ratio of 1∶1 according to the psoriasis area and severity index (PASI) score and age. PASI, physician′s global assessment (PGA) , and body surface area (BSA) scores were assessed at weeks 4, 8 and 12 after the start of treatment, and adverse drug reactions were recorded. Statistical analysis was mainly carried out by using Mann-Whitney U test, Fisher′s exact test and generalized estimating equations. Results:At weeks 4 and 8, the proportions of patients achieving PASI75 and PASI90 were significantly higher in the biologics group (PASI75: 7/10, 10/10, PASI90: 5/10, 9/10, respectively) than in the methotrexate group (PASI75: 1/10, 5/10, PASI90: 0, 1/10, respectively; all P < 0.05) , while there was no significant difference between the biologics group and methotrexate group at week 12 (PASI75: 10/10 vs. 8/10, PASI90: 9/10 vs. 4/10, both P > 0.05) . There were no significant differences in the PASI, BSA or PGA scores between the two groups at baseline (all P > 0.05) , while the biologics group showed significantly decreased PASI and BSA scores at weeks 4, 8 and 12, and significantly decreased PGA score at week 8 compared with the methotrexate group (PASI: Z = 2.50, 3.56, 2.63, respectively; BSA: Z = 2.87, 3.57, 2.40, respectively; PGA: Z = 2.81; all P<0.05) . Analysis of changes over time showed that the PASI, PGA and BSA scores in the biologics group significantly decreased at weeks 4, 8 and 12 compared with those at baseline (all P<0.01) ; the PASI and PGA scores significantly decreased at weeks 8 and 12 compared with the corresponding scores at week 4 (all P<0.05) ; however, there were no significant differences in the PASI, PGA or BSA scores between week 12 and 8 (all P>0.05) . In the methotrexate group, the PASI, PGA and BSA scores at weeks 4, 8 and 12 were all significantly lower than the corresponding scores at the previous adjacent time points (all P<0.05) . There was no significant difference in the incidence of adverse reactions between the two groups ( P = 0.650) , and no serious adverse reactions occurred in either group. The main adverse reaction was infection in the biologics group, while infection and elevation of transaminase levels were common in the methotrexate group. Conclusion:Biologics and methotrexate were both effective and safe for the treatment of severe pediatricplaque psoriasis, and biologics facilitated rapider achievement of PASI75 and PASI90 compared with methotrexate.

Effects of SuperPATH approach versus posterolateral approach in total hip replacement on inflammatory response, hip function, and quality of life in patients with hip diseases / 中国基层医药

Objective:To investigate the effects of SuperPATH approach versus conventional posterolateral approach in total hip replacement on inflammatory response, hip function, and quality of life in patients with hip diseases. Methods:The clinical data of 140 patients with hip diseases who underwent total hip replacement in Shanxian Central Hospital from March 2017 to May 2019 were retrospectively analyzed. These patients were divided into SuperPATH approach ( n = 70) and posterolateral approach ( n = 70) groups. Operation-related indexes, inflammatory response indexes, hip function, quality of life, and pain were compared between the two groups. Results:Intraoperative blood loss was significantly less in the SuperPATH approach group than in the posterolateral approach group [(105.40 ± 15.11) mL vs. (196.89 ± 24.26) mL, t = 26.74, P < 0.001]. Incision length, postoperative time to getting out of bed, length of hospital stay in the SuperPATH approach group were (6.85 ± 1.42) cm, (2.92 ± 0.28) days, and (6.67 ± 1.36) days, respectively, which were significantly shorter than those in the posterolateral approach group [(13.07 ± 1.89) cm, (8.36 ± 1.45) days, (10.91 ± 1.34) days, t = 19.36, 30.82, 18.58, P < 0.001]. Operative time was significantly longer in the SuperPATH approach group than in the posterolateral approach group [(69.38 ± 8.62) minutes vs. (60.45 ± 7.79) minutes, t = 6.43, P < 0.001). The scores of social role functioning, general health perceptions, vitality, mental health, bodily pain, emotional role functioning, physical functioning, and physical functioning measured 6 months after surgery were significantly higher in the SuperPATH approach group than in the posterolateral approach group ( t = 9.12, 11.80, 11.64, 11.69, 6.45, 11.79, 6.04, 10.74, all P < 0.001). There were no significant differences in C-reactive protein and erythrocyte sedimentation rate measured 3 and 14 days after surgery between the two groups (both P > 0.05). Harris score used for evaluation of hip function 1 month after surgery was significantly higher in the SuperPATH approach group than in the posterolateral approach group [(76.42 ± 4.17) points vs. (69.37 ± 5.11) points, t = 8.94, P < 0.001]. The Visual Analog Scale score 3 days after surgery was significantly lower in the SuperPATH approach group than in the posterolateral approach group [(3.18 ± 0.21) points vs. (4.26 ± 0.29) points, t = 25.23, P < 0.001]. Conclusion:Compared with the conventional posterolateral approach, the SuperPATH approach for total hip arthroplasty takes longer operative time, but it can better reduce early postoperative pain, promote hip function recovery, and improve quality of life.

Research progress of deficiency of interleukin-36 receptor antagonist and cutaneous sterile pustulosis / 中华实用儿科临床杂志

Cutaneous sterile pustulosis is categorized as a non-infectious and non-follicular impetigo, with a low prevalence and difficulty in the treatment.Deficiency of interleukin(IL)-36 receptor antagonist (DITRA) is an auto inflammatory disease featured by the decreased interleukin-36 receptor antagonist (IL-36Ra) activity caused by IL36 RN mutation.Functional or structural defects of IL-36Ra increase the secretion of inflammatory and pro-inflammatory factors by keratinocytes, macrophages and dendritic cells.Upregulation of IL-36 receptor agonists induce type 17 helper T lymphocytes to secrete IL-17, which is essential for the onset of multiple subtypes of aseptic pustulosis.Research on the relationship between DITRA and cutaneous sterile pustulosis is important for developing targeted therapies.

Establishment of a predictive model for the prognosis of patients with hepatitis B virus-related acute-on-chronic liver failure treated with plasma exchange and double plasma molecular adsorption system alone or in combination / 临床肝胆病杂志

Objective To observe the 24-week survival status of patients with hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF) treated with plasma exchange (PE) and double plasma molecular adsorption system (DPMAS) alone or in combination, and to establish a predictive model for 24-week prognosis. Methods Related clinical data were collected from 133 patients with HBV-ACLF who received PE and DPMAS alone or in combination in The Affiliated Provincial Hospital of Anhui Medical University from January 2015 to December 2019, and according to the survival status at the 24-week follow-up after treatment, they were divided into survival group with 71 patients and death group with 62 patients. A total of 55 patients with HBV-ACLF who received PE and DPMAS alone or in combination in The Second Affiliated Hospital of Anhui Medical University from January 2018 to January 2020 were enrolled as validation group to validate the performance of the model. Related clinical data included mode of artificial liver support therapy, age, sex, total bilirubin (TBil), international normalized ratio (INR), creatinine (Cr), serum sodium, platelet count (PLT), albumin (Alb), and presence or absence of ascites, hepatorenal syndrome, hepatic encephalopathy, and gastrointestinal bleeding. The t -test was used for comparison of normally distributed continuous data between two groups, and the Wilcoxon rank-sum test was used for comparison of continuous data with skewed distribution between two groups; the chi-square test and the Fisher's exact test were used for comparison of categorical data between groups. The Cox regression model was used to analyze the influencing factors for the prognosis of HBV-ACLF patients after PE and DPMAS alone or in combination and establish a predictive model; the receiver operator characteristic (ROC) curve was plotted and the DeLong method was used to compare the area under the ROC curve (AUC) between the new predictive model and Model for End-Stage Liver Disease (MELD)/MELD combined with serum sodium concentration (MELD-Na) scores. Results At 24 weeks after treatment, 71 patients survived and 62 patients died in the modeling group. The Cox regression analysis showed age (hazard ratio [ HR ]=1.030, P =0.013), TBil ( HR =1.018, P < 0.001), INR ( HR =1.517, P < 0.001), and PLT ( HR =0.993, P =0.04) were independent influencing factors for 24-week survival. According to the results of the Cox regression analysis, a prognostic model for HBV-ACLF patients treated with PE and DPMAS alone or in combination was established as ATIP=0.029×age (years)+0.018×TBil (mg/dL)+0.417×INR-0.007×PLT (10 9 /L). Both the modeling group and the validation group showed that the ATIP model had a better predictive performance than MELD and MELD-NA scores(all P < 0.05). Conclusion Age, TBil, INR, and PLT are independent influencing factors for the 24-week survival of HBV-ACLF patients treated with PE and DPMAS alone or in combination, and the ATIP model has a good performance in predicting the 24-week prognosis of HBV-ACLF patients treated with PE and DPMAS alone or in combination.

Objective:To investigate the expressions and significances of transforming growth factor β 1 (TGF-β 1) and dimethylarginine dimethylaminohydrolase 2 (DDAH2) in different stages of early-stage lung adenocarcinoma, and to provide basis for accurate pathological diagnosis of lung adenocarcinoma. Methods:Sixty-two surgical specimens from patients with early-stage lung adenocarcinoma in Shanxi Bethune Hospital from January 2012 to June 2019 were selected. Most of the specimens contained more than one pathological type. According to the pathological types, they were divided into three groups: 18 cases of atypical adenomatous hyperplasia (AAH), 60 cases of adenocarcinoma in situ (AIS), and 55 cases of invasive carcinoma (CA) component in minimally invasive adenocarcinoma (MIA) and lepidic predominant adenocarcinoma (LPA), and the wall attached growth patterns were selected as control group. Immunohistochemistry was used to detect the expressions of TGF-β 1 and DDAH2 proteins in different pathological types of lesions and control tissues, and the correlation among them was analyzed. Results:TGF-β 1 and DDAH2 proteins were expressed in normal lung tissue epithelial cells, and the positive rates were high [46.8% (29/62) and 98.4% (61/62)]. The positive rates of TGF-β 1 and DDAH2 proteins in epithelial cells of AAH, AIS and CA increased gradually, the positive rate of TGF-β 1 protein was 16.7% (3/18), 31.7% (19/60) and 70.9% (39/55), the positive rate of DDAH2 protein was 66.6% (12/18), 81.7% (49/60) and 90.1% (49/55), and the differences of positive rates among different pathological types were statistically significant (all P < 0.01). The positive rates of TGF-β 1 and DDAH2 protein in interstitial fibroblasts of normal lung tissue, AAH, AIS and CA increased gradually, the positive rate of TGF-β 1 protein was 11.3% (7/62), 61.1% (11/18), 72.3% (44/60), and 83.6% (46/55), the positive rate of DDAH2 protein was 0 (0/62), 22.2% (4/18), 65.0% (39/60), and 98.2% (54/55), and the differences of positive rates among different pathological types were statistically significant (all P < 0.01). In lung adenocarcinoma tissues, there was a positive correlation between the expression of TGF-β 1 in epithelial cells and the expression of DDAH2 in interstitial fibroblasts ( r = 0.221, P = 0.011). Conclusions:The expression trend of TGF-β 1 and DDAH2 proteins in different pathological types of early-stage lung adenocarcinoma lesions may relate to the degree of lesions. The combined detection of TGF-β 1 and DDAH2 proteins is expected to be a biomarker for the auxiliary diagnosis of early-stage lung adenocarcinoma with different pathological types.

Application of multiple MLL gene rearrangement detection techniques for children with acute mononuclear leukemia / 中华医学遗传学杂志

Objective@#To assess the value of detecting multiple rearrangements of MLL gene in children with acute mononuclear leukemia (AML).@*Methods@#Eighty six children with AML were analyzed by fluorescence in situ hybridization (FISH), chromosomal karyotyping and multiplex reverse transcription-PCR (RT-PCR).@*Results@#Cross signals were detected by FISH in 26 cases, and 30.2% were detected with MLL gene rearrangements. R-band karyotyping analysis revealed 14 translocations with breakages involving 11q23 and 5 other aberrations, which yielded an overall detection rate of 22.1%. Multiple RT-PCR has detected 12 fusion genes produced by the MLL translocation, which yielded a detection rate of 14.0%. A significant difference was found in the detection rate of the three methods (P<0.05).@*Conclusion@#Combined use of FISH, chromosomal karyotyping and multiplex RT-PCR can improve the detection of MLL gene rearrangements and provide important clues for clinical diagnosis, treatment and prognosis of AML.

The value of detecting MLL gene rearrangement in children with acute monocytic leukemia / 中华医学遗传学杂志

OBJECTIVE@#To assess the value of detecting the rearrangement of mixed lineage leukemia (MLL) gene in children with acute mononuclear leukemia (AML).@*METHODS@#Dual-color fluorescence in situ hybridization (FISH) probe was used to detect MLL gene rearrangement in 68 children with AML by interphase FISH. The results were compared with that of conventional G banding chromosomal analysis.@*RESULTS@#Among the 68 children, 28 were detected by FISH with positive hybridization signals, with a detection rate for MLL gene rearrangement being 41.2%. Twelve (17.6%) reciprocal translocations and interruption of 11q23 were detected by G banding analysis. The difference in the detection rates between the two methods was statistically significant (P< 0.05).@*CONCLUSION@#The sensitivity of FISH assay for MLL gene rearrangement was significantly higher than that of G banding chromosomal karyotyping. Combined use of both methods for children with AML can improve the detection rate of MLL gene rearrangements and provide crucial clues for clinical diagnosis, treatment and prognosis.
