RESUMEN
OBJECTIVE@#To retrospectively analyze efficacy of single structure internal fixation and double structure internal fixation in the treatment of ipsilateral femoral shaft and neck fracture, and analyze their indications.@*METHODS@#From June 2015 to December 2020, 21 patients with ipsilateral femoral shaft and femoral neck fracture were treated, including 14 males and 7 females, aged 23 to 69 years old with an average of(38.1±12.9) years old. According to different femoral shaft fracture sites, some patients were fixed with cephalomedullary implant for both femoral neck and the femoral shaft(single structure, InterTan or PFNA Ⅱ), some patients were fixed with cannulated screws for the femoral neck and a retrograde locking nail for the femoral shaft (dual structure), and postoperative function and complications were recorded during follow-up. In 10 cases of single-structure fixation, the femoral necks were all basicervical fractures, and the femoral shaft fractures were located in the proximal isthmus;11 cases were double-structure fixation, 9 cases in 11 were basal type of femoral neck, 2 cases in 11 were neck type, and the femoral shaft fractures were located in the isthmus and the distal isthmus.@*RESULTS@#All patients were followed up for 12 to 27 months. No femoral head necrosis, deformity, delay or nonunion occurred in the patients with single-structure fixation, and no delayed union or nonunion occurred in femoral shaft fractures;At the final follow-up, Harris score of patients with single-structure fixation was 91.8±4.1, with 8 cases were excellent and 2 cases were good. The fractures of patients with dual-structure fixation achieved good union without femoral head necrosis, except 1 case of femoral shaft fracture had delayed union;At the final follow-up, Harris score of patients with dual-structure fixation was 92.4±5.9, 7 cases were excellent, 3 cases were good, and 1 case was fair.@*CONCLUSION@#Good reduction and fixation is the key to the treatment of such fractures. Both the single-structure fixation and the dual-structure fixation are good methods, and it should be selected according to the locations of femoral shaft and femoral neck fractures. Single-structure fixation is a good choice for femoral shaft fractures located at the proximal isthmus and basal femoral neck fractures. For isthmus and distal femoral shaft fractures combined with ipsilateral femoral neck fractures, dual-structure fixation is recommended.

As a biocatalyst, enzyme has the advantages of high catalytic efficiency, strong reaction selectivity, specific target products, mild reaction conditions, and environmental friendliness, and serves as an important tool for the synthesis of complex organic molecules. With the continuous development of gene sequencing technology, molecular biology, genetic manipulation, and other technologies, the diversity of enzymes increases steadily and the reactions that can be catalyzed are also gradually diversified. In the process of enzyme-catalyzed synthesis, the majority of common enzymatic reactions can be achieved by single enzyme catalysis, while many complex reactions often require the participation of two or more enzymes. Therefore, the combination of multiple enzymes together to construct the multi-enzyme cascade reactions has become a research hotspot in the field of biochemistry. Nowadays, the biosynthetic pathways of more natural products with complex structures have been clarified, and secondary metabolic enzymes with novel catalytic activities have been identified, discovered, and combined in enzymatic synthesis of natural/unnatural molecules with diverse structures. This study summarized a series of examples of multi-enzyme-catalyzed cascades and highlighted the application of cascade catalysis methods in the synthesis of carbohydrates, nucleosides, flavonoids, terpenes, alkaloids, and chiral molecules. Furthermore, the existing problems and solutions of multi-enzyme-catalyzed cascade method were discussed, and the future development direction was prospected.

@#Abstract:Objective To analyze the stabilities of neuraminidase(NA)in influenza vaccine at different temperatures and provide a reference for further complete understanding of overall shelf life of vaccines. Methods Monovalent bulks of influenza H1N1,H3N2 and B vaccines were stored at 4(low temperature),25(room temperature)and 37 ℃(changed temperature)for 0. 5,2,7,24 and 48 h separately,using that at 100 ℃(extreme temperature)for 1 h as control,and determined for NA activity by enzyme⁃linked lectin method. Results The NA activities of influenza H1N1 vaccines stored at 25 and 37 ℃ decreased significantly with the increasing of time. No significant decreases were observed in H3N2 and B vaccines even after storage at two non⁃storage temperatures for 48 h. However,all the NA activities of three vaccines decreased at 100 ℃. Conclusion Both H3N2 and B vaccines showed high stability at abnormal storage temperatures not more than 37 ℃,while H1N1 vaccine was relatively sensitive to the temperature for storage.

@#Objective To construct luciferase reporter plasmids of truncated fragments of different lengths of human guanylate binding protein 5(GBP5)gene promoter and analyze the transcriptional activity of each fragment to determine the core regulatory region.Methods GBP5promoter sequence was amplified by PCR,truncated into five fragments of different lengths and connected to pGL3-basic plasmid.The constructed recombinant plasmids pGL3-GBP5-11/21/31/41/51were transfected into 293FT cells and detected for luciferase activity.The binding sites of transcription factors in GBP5promoter region were predicted by JASPAR software,and Yin-Yang transcription factor 1(YY1)targeting the core regulatory region was selected and verified for the transcriptional regulatory activity.The CDS sequence of YY1 was amplified by PCR to construct the overexpression plasmid pIRES2-EGFP-YY1,which was then co-transfected to 293FT cells with plasmids pGL3-GBP5-21(-1 623 ~ +47 bp)and internal reference plasmid pRL-CMV,and detected for luciferase activity to analyze the regulation of transcription factor YY1 on GBP5 promoter activity.Results Colony PCR and double enzyme digestion identification proved that the plasmid of human GBP5 promoter reporter gene was correctly constructed;JASPAR software predicted that there were multiple transcription factor binding sites such as STAT1,YY1 and Foxp3 in GBP5promoter region.Double luciferase activity assay showed that pGL3-GBP5-21(-1 623 ~ +47 bp)showed the highest promoter activity,while the promoter activity of pGL3-GBP5-41(-520 ~ +47 bp)decreased significantly,suggesting that the core region of GBP5 promoter was located at upstream-1 623 ~-520 bp of 5 'UTR;Overexpression of YY1 significantly activated the GBP5 promoter activity and regulated the expression of GBP5.Conclusion The core regulatory region of human GBP5 promoter was located in upstream-1 623 ~-520 bp of the 5 'UTR,with a binding site of transcription factor YY1 existing in this region.Meanwhile,overexpression of YY1 significantly effected the activity of GBP5 promoter.
RESUMEN
Objective: To analyze the clinical and molecular diagnostic status of Fanconi anemia (FA) in China. Methods: The General situation, clinical manifestations and chromosome breakage test and genetic test results of 107 pediatric FA cases registered in the Chinese Blood and Marrow Transplantation Registry Group (CBMTRG) and the Chinese Children Blood and Marrow Transplantation Registry Group (CCBMTRG) from August 2009 to January 2022 were analyzed retrospectively. Children with FANCA gene variants were divided into mild and severe groups based on the type of variant, and Wilcoxon-test was used to compare the phenotypic differences between groups. Results: Of the 176 registered FA patients, 69 (39.2%) cases were excluded due to lack of definitive genetic diagnosis results, and the remaining 107 children from 15 hospitals were included in the study, including 70 males and 37 females. The age at transplantation treatment were 6 (4, 9) years. The enrolled children were involved in 10 pathogenic genes, including 89 cases of FANCA gene, 7 cases of FANCG gene, 3 cases of FANCB gene, 2 cases of FANCE gene and 1 case each of FANCC, FANCD1, FANCD2, FANCF, FANCJ, and FANCN gene. Compound heterozygous or homozygous of loss-of-function variants account for 69.2% (72/104). Loss-of-function variants account for 79.2% (141/178) in FANCA gene variants, and 20.8% (37/178) were large exon deletions. Fifty-five children (51.4%) had chromosome breakage test records, with a positive rate of 81.8% (45/55). There were 172 congenital malformations in 80 children.Café-au-Lait spots (16.3%, 28/172), thumb deformities (16.3%,28/172), polydactyly (13.9%, 24/172), and short stature (12.2%, 21/172) were the most common congenital malformations in Chinese children with FA. No significant difference was found in the number of congenital malformations between children with severe (50 cases) and mild FANCA variants (26 cases) (Z=-1.33, P=0.185). Conclusions: FANCA gene is the main pathogenic gene in children with FA, where the detection of its exon deletion should be strengthened clinically. There were no phenotypic differences among children with different types of FANCA variants. Chromosome break test is helpful to determine the pathogenicity of variants, but its accuracy needs to be improved.

Chimeric RNA is a fusion transcript composed of exons from two or more different genes and generated by chromosome rearrangement or RNA splicing. Chimeric RNAs have the potential to encode novel proteins or function as non-coding RNAs. Chimeric RNAs were ubiquitously expressed across different cancers and normal tissues. To date, mechanistic and functional studies of chimeric RNAs still remain unclear. Precise definition and terminology in the research field of chimeric RNA will be discussed in this review. The formation, classification and clinical significance of chimeric RNAs in cancer progression will be summarized. Previous studies showed that products of chimeric RNAs may play important roles in regulating cell proliferation, motility, invasion and apoptosis through encoded fusion proteins or long non-coding chimeric RNAs. In cancer, chimeric RNA and its encoded specific protein or non-coding RNA can regulate tumorigenesis by changing cell phenotypes or directly affecting gene expression or regulatory pathways, which have the potential to be important diagnostic biomarkers and therapeutic targets. In recent years, more and more cancer-specific chimeric RNAs have been discovered from multiple types of cancers and used as therapeutic targets due to their vital roles in disease prognosis. Therefore, this review will focus on the functions and applications of chimeric RNAs in different tumors, which can shed a light on cancer diagnosis and therapeutics from the new perspective.

Hypoxic preconditioning could improve the survival of mesenchymal stem cells (MSCs) in ischemic or hypoxic environments, but its exact mechanism remains to be further explored. This study aims to determine the role of lysine crotonylation (Kcr) in regulating the survival and proliferation of peripheral blood mesenchymal stem cells (PBMSCs) in the hypoxic culture. PBMSCs were isolated and cultured from rat peripheral blood mononuclear cells, and their surface markers were identified by flow cytometry. PBMSCs were first subjected to hypoxic/ normoxic preconditioning: hypoxic (1% O
RESUMEN
Hepatic cystic echinococcosis is a chronic parasitic disease caused by the infection with the larvae of Echinococcus granulosus in human or animal liver tissues. As a chronic active infectious disease, tuberculous empyema mainly invades the pleural space and then causes visceral and parietal pleura thickening. It is rare to present comorbidity for hepatic cystic echinococcosis and tuberculous empyema. This case report presents a case of hepatic cystic echinococcosis complicated with tuberculous empyema misdiagnosed as hepatic and pulmonary cystic echinococcosis, aiming to improve clinicians’ ability to distinguish this disorder.
RESUMEN
PURPOSE@#To investigate the clinical value of urine interleukin-18 (IL-8), neutrophil gelatinase-associated lipocalin (NGAL) and kidney injury molecule-1 (KIM-1) for the early diagnosis of acute kidney injury (AKI) in patients with ureteroscopic lithotripsy (URL) related urosepsis.@*METHODS@#A retrospective study was carried out in 157 patients with urosepsis after URL. The patients were divided into AKI group and non-AKI group according to the Kidigo guideline and urine IL-8, NGAL and KIM-1 levels were detected by enzyme-linked immunosorbent assay at 0, 4, 12, 24 and 48 h after the surgery. Receiver operating characteristic curve (ROC) was used to evaluate the diagnostic value of these three biomarkers for postoperative AKI.@*RESULTS@#The level of urine IL-8, NGAL and KIM-1 in AKI group was significantly higher than that in non-AKI group at 4, 12, 24 and 48 h (p < 0.01). The ROC analysis showed the combined detection of urine IL-8, NGAL and KIM-1 at 12 h had a larger area under curve (AUC) than a single marker (0.997, 95% CI: 0.991-0.998), and the sensitivity and specificity were 98.2% and 96.7%, respectively. Pearson correlation analysis showed that the levels of urine NGAL at 4, 12, 24 and 48 h in AKI patients were positively correlated with the levels of urine KIM-1 and IL-18 (p < 0.01).@*CONCLUSION@#AKI could be quickly recognized by the elevated level of urine IL-8, NGAL and KIM-1 in patients with URL-related urosepsis. Combined detection of the three urine biomarkers at 12 h after surgery had a better diagnostic performance, which may be an important reference for the early diagnosis of AKI.

Objective To investigate the relationship between the expression of glutathione peroxidase(GPX)genes and the clinical prognosis in glioma patients,and to construct and evaluate the model for predicting the prognosis of glioma. Methods The clinical information and GPX expression of 663 patients,including 153 patients of glioblastoma(GBM)and 510 patients of low-grade glioma(LGG),were obtained from The Cancer Genome Atlas(TCGA)database.The relationship between GPX expression and patient survival was analyzed.The key GPX affecting the prognosis of glioma was screened out by single- and multi-factor Cox's proportional-hazards regression models and validated by least absolute shrinkage and selection operator(Lasso)regression.Finally,we constructed the model for predicting the prognosis of glioma with the screening results and then used concordance index and calibration curve respectively to evaluate the discrimination and calibration of model. Results Compared with those in the control group,the expression levels of GPX1,GPX3,GPX4,GPX7,and GPX8 were up-regulated in glioma patients(all P<0.001).Moreover,the expression levels of other GPX except GPX3 were higher in GBM patients than in LGG patients(all P<0.001).The Kaplan-Meier curves showed that the progression-free survival of GBM with high expression of GPX1(P=0.013)and GPX4(P=0.040),as well as the overall survival,disease-specific survival,and progression-free survival of LGG with high expression of GPX1,GPX7,and GPX8,was shortened(all P<0.001).GPX7 and GPX8 were screened out as the key factors affecting the prognosis of LGG.The results were further used to construct a nomogram model,which suggested GPX7 was the most important variable.The concordance index of the model was 0.843(95%CI=0.809-0.853),and the calibration curve showed that the predicted and actual results had good consistency. Conclusion GPX7 is an independent risk factor affecting the prognosis of LGG,and the nomogram model constructed with it can be used to predict the survival rate of LGG.

OBJECTIVE@#To analyze the difference in clinical efficacy of minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) under Quadrant channel system combined with microscope and percutaneous pedicle screw in the treatment of degenerative lumbar spondylolisthesis.@*METHODS@#A total of 114 patients with single-segment degenerative lumbar spondylolisthesis from June 2015 to February 2019, were divided into three groups according to the surgical methods, such as the MIS-TLIF under the microscope surgery group ( microscope group), MIS-TLIF combined with percutaneous pedicle screw technique surgery group(percutaneous group) and posterior lumbar interbody fusion surgery group (open group). In the microscope group, there were 12 males and 26 females, aged from 42 to 83 years with an average of (63.29±9.09) years. In the percutaneous group, there were 16 males and 22 females, aged from 45 to 82 years with an average of (63.37±7.50) years. In the open group, there were 12 males and 26 females, aged from 51 to 82 years with an average of (63.76±8.21) years. The general conditions of operation, such as operation time, intraoperative blood loss, postoperative drainage, length of surgical incision, frequency of intraoperative fluoroscopy and postoperative time of lying in bed were recorded to analyze the differences in surgical related indicators. Visual analogue scale (VAS) of waist and leg pain in preoperative and postoperative period (3 days, 3 months, 6 months and 12 months) were recorded to evaluate pain remission;Oswestry Disability Index(ODI), Japanese Orthopaedic Association (JOA) score were recorded to evaluate the recovery of waist and leg function on preoperative and postoperative 12 months. The lumbar spondylolisthesis rate and intervertebral height at 12 months after operation were recorded to evaluate the reduction of spondylolisthesis. The Siepe intervertebral fusion standard was used to analyze the intervertebral fusion rate at 12 months after operation.@*RESULTS@#①All 114 patients were followed up more than 1 year, and no complications related to incision infection occurred. In the microscope group, there was 1 case of subcutaneous effusion 8 days after operation. After percutaneous puncture and drainage, waist compression, and then the healing was delayed. In the percutaneous group, 2 cases of paravertebral muscle necrosis occurred on the side of decompression, and the healing was delayed after debridement. In open group, there was 1 case of intraoperative dural tear, which was packed with free adipose tissue during the operation. There was no postoperative cerebrospinal fluid leakage and other related complications.① Compared with microscope group, percutaneous group increased in operation time, intraoperative blood loss, postoperative wound drainage, surgical incision length, intraoperative fluoroscopy times, and postoperative bed rest time. In open group, intraoperative blood loss, postoperative wound drainage, surgical incision length, and postoperative bed rest time increased, but the intraoperative fluoroscopy time decreased. Compared with percutaneous group, the intraoperative blood loss, wound drainage, surgical incision length, and postoperative bed rest time in open group increased, but operative time and the intraoperative fluoroscopy time decreased(P<0.05). ②ODI and JOA scores of the three groups at 12 months after operation were improved compared with those before operation (P<0.05), but there was no significant difference between the three group(P>0.05). ③Compared with microscope group, the VAS of low back pain in percutaneous group increased at 3 days after operation, and VAS of low back pain in open group increased at 3 days, and 12 month after operation. Compared with percutaneous group, the VAS low back pain score of the open group increased at 3 months after operation (P<0.05). ④ The lumbar spondylolisthesis rate of the three groups of patients at 12 months afrer operation was decreased compared with that before operation(P<0.05), and the intervertebral heigh was increased compared with that before operation(P<0.05), however, there was no significant difference among three groups at 12 months afrer operation(P>0.05). ⑤ There was no significant difference between three groups in the lumbar fusion rate at 12 months afrer operation(P>0.05).@*CONCLUSION@#The MIS-TLIF assisted by microscope and the MIS-TLIF combined with percutaneous pedicle screw are safe and effective to treat the degenerative lumbar spondylolisthesis with single-segment, and the MIS-TLIF assisted by microscope may be more invasive, cause less blood loss and achieve better clinical efficacy.

Objective: To explore the risk factors for syncope in children with severe idiopathic pulmonary arterial hypertension (IPAH). Methods: Forty-four patients (age<18 years) with IPAH admitted to the Department of Pediatric Cardiology, Beijing Anzhen Hospital between May 2011 and October 2021 were retrospectively included. Patients were devided into syncope group and non-syncope group. Clinical manifestation and hemodynamic parameters including echocardiography, blood tests, right heart catheterization and acute pulmonary vascular expansion test were compared between two groups. Comparisons between groups were performed with unpaired Student t test, or Mann-Whitney U test or chi-square test. Logistic regression was used to calculate the odds ratio (OR) for parameters with statistically significant differences between groups and analyze the statistical correlation. Results: Among the 44 patients, 16 were males, the onset age was (7.2±3.9) years. Twenty-four (55%) children presented with 1 to 11 times of episodes of syncope, and 18 cases of whom induced by physical activity. Syncope group had a larger proportion of New York Heart Association (NYHA) heart function class Ⅲ-Ⅳ (67% (16/24) vs. 25% (5/20), χ2=7.59, P=0.006), higher brain natriuretic peptide (BNP) value ((251±39) vs. (61±40) pg/L, t=-2.18, P=0.035), higher pulmonary-to-aorta diameter ratio (1.6±0.4 vs. 1.4±0.2, t=-2.25, P=0.030) and larger pulmonary vascular resistance index ((22±11) vs. (16±7) WU/m2, t=-2.13, P=0.039) compared with non-syncope group. The proportion of patent foramen ovale (4% (1/24) vs. 45% (9/20), χ2=10.36, P=0.001), left ventricular ejection fraction (LVEF) ((68±5)% vs. (72±8)%, t=2.23, P=0.031) and the positive rate of acute pulmonary vascular expansion test (8% (2/24) vs. 35% (7/20), χ2=4.77, P=0.029) of syncope group were significantly lower than those of non-syncope group. Multiple Logistic regression analysis showed that NYHA heart function Ⅲ-Ⅳ (OR=6.787, 95%CI 1.445-31.880), pulmonary vascular resistance index (OR=1.247, 95%CI 1.020-1.525) and BNP (OR=1.036, 95%CI 1.007-1.066) were independent risk factors for syncope. The patent foramen ovale (OR=0.010, 95%CI 0.000-0.586) was a protective factor for syncope. Conclusions: NYHA cardiac function grade, pulmonary vascular resistance index and BNP are independent risk factors for syncope. Patent foramen ovale is a protective factor for syncope. Exercise is the main inducement of syncope in children with IPAH.

Methods According to Anthropometric Method, 286 Tajik adults (male 121, female 165) in Aketao, Xinjiang were recruited and analyzed. The survey included 12 observation indicators of head and face, 19 measuring indicators of head and face, 12 indexes of head and face and its classification. Results The indicators of head length, head breadth, head height, minimum frontal breadth, face breadth, bigonial breadth, nose breadth, mouth breadth, auricular height, physiognomic facial height, morphological facial height, nasal length, nasal height, physiognomic ear length, physiognomic ear breadth, zygomatic protection, nasal root height, nasal profile, nasal base of Tajik adults in Aketao had gender differences (P < 0. 05). Compared with the Tajik adults in Aketao and Taxkorgan, the type indicators of head and face of zygomatic protection, direction of eyeslits, nasal root height, nasal base, maximal diameter of nostrils, lobe types, nreadth-height index of head type, morphological facial index type, nasal index type had regional differences (P<0. 05). The cluster analysis showed that Tajik adults have unique characteristics of head and face, which were grouped separately and were more similar to Iranians. Conclusion Tajik adults in Aketao have the characteristics of head and face of the West Eurasian. The characteristics of head and face of Tajik adults in Aketao and Taxkorgan are somewhat different. From characteristics of head and face, they may be related to the Eastern Iranian tribe.
RESUMEN
Objective To discuss the main reasons for the difference of sedum development between Daur adults in Inner Mongolia and Xinjiang. Methods Nine circumference values and six skin fold thickness of 544 adults of Daur nationality (304 in Xinjiang and 240 in Inner Mongolia) were investigated by random sampling. Circumferences, skin fold thickness and obesity indexes of Daur nationality in Xinjiang and Inner Mongolia were analyzed. Results There were significant differences in 8 circumference without thigh circumference, 2 skin fold thickness such as triceps skinfold, subscapularis skinfold, 3 obesity indexes such as Verv index, body fat rate, body mass index(BMI). Correspondence analysis showed that subcutaneous fat development was stronger in northern regions than in southern regions. Conclusion The Daur nationality in Inner Mongolia has more fat and less muscle than that in Xinjiang. The problems of overweight and obesity in both regions are serious. It is suggested to pay attention to exercise and diet. Low temperature,lack of physical exercise, low temperature, low economic and medical standards and unhealthy eating habits can thicken subcutaneous fat.
RESUMEN
Objective To investigate the distribution characteristics of Oncomelania hupensis in Guangxi Zhuang Autonomous Region, so as to provide insights into the assessment of the risk of schistosomiasis transmission and the scientific formulation of the schistosomiasis surveillance strategy. Methods From 2015 to 2019, a total of 19 national schistosomiasis surveillance sites were assigned in Guangxi Zhuang Autonomous Region, including 4 fixed sites and 15 mobile sites. Snail survey was performed by means of systematic sampling in combination with environmental sampling, and the infection of Schistosoma japonicum was detected by the crushing method combined with loop-mediated isothermal amplification (LAMP) assay. Results From 2015 to 2019, snail habitats were detected at areas of 17 040 to 39 527 m2, including 6 214 m2 emerging snail habitats and 16 563 m2 re-emerging snail habitats. The overall mean density of living snails was 0.019 2 snails/0.1 m2 and the occurrence of frames with snails was 1.11% in the national schistosomiasis surveillance sites; however, no S. japonicum infection was identified in snails. The area of snail habitats increased by 121.46% in the national surveillance sites in 2019 as compared to that in 2015; however, 50.34% (Z = −0.422, P > 0.05) and 42.85% (χ2 = 130.41, P < 0.01) reductions were seen in the overall means density of living snails and the occurrence of frames with snails. All snail habitats were distributed in the 4 fixed surveillance sites, and were mainly found in ditches, paddy fields and dry lands, with weeds as the primary vegetation type. Conclusions There are still risk factors leading to re-emergent transmission of schistosomiasis in Guangxi Zhuang Autonomous Region, such as local snail spread, and the monitoring of schistosomiasis remains to be reinforced to further consolidate the achievements of schistosomiasis elimination in the region.
