OBJECTIVE: To compare clinical effect of anterior tibial plateau fracture line and anterior tibial fenestration reduction in treating anterolateral tibial plateau column fracture combined with posterior lateral column collapse. METHODS: Fifty-two patients with Schatzker typeⅡ tibial plateau anterolateral column fracture combined with posterolateral column collapse admitted from January 2016 to December 2021 were retrospectively analyzed and divided into two groups according to fracture reduction methods. There were 27 patients in fracture line group, including 19 males and 8 females, aged from 26 to 62 years old with an average of (43.2±11.4) years old;the time from injury to operation ranged from 4 to 8 days with an average of (5.8±1.5) days;treated with reduction and internal fixation via fracture line of lateral platform front. There were 25 patients in fenestrate group, including 13 males and 12 females, aged from 22 to 69 years old with an average of (40.8±11.1) years old;the time from injury to operation ranged from 4 to 8 days with an average of (6.0±1.4) days;treated with tibial fenestration reduction and internal fixation. The amount of bone graft, operation time, fracture healing time and complications were compared between two groups. Posterior slope angle (PSA) and posterior slope angle of the lateral tibial plateau was compared before surgery, 2 days and 6 months after surgery. The knee function was evaluated by Hospital for Speical Surgery (HSS) at 2 days and 6 months after surgery, respectively. Fracture reduction was evaluated by Rasmussen anatomic score of knee joint. RESULTS: Both of group were followed up from 12 to 24 months (16.0±3.4) months. No redisplacement of fracture, internal and external inversion deformity of knee joint, or instability of knee joint were found between two groups during follow-up. In fracture line group, 1 patient occurred wound fat liquefaction and 2 patients occurred lower limb intermuscular venous thrombosis occurred. In fenestration group, 1 patient occurred joint stiffness, 1 patient occurred lower limb intermuscular venous thrombosis, and 1 patient occurred superficial wound infection;there were no significant difference in complications between two groups (P>0.05). Bone graft volume, operative time and fracture healing time in fracture line group were (3.6±2.3) cm³, (123.4±18.2) min and (13.8±1.8) weeks, while in feneplast group were (4.8±1.8) cm³, (135.5±22.5) min and (15.2±2.0) weeks, respectively;the difference between two groups was statistically significant (P<0.05). The collapse depth of lateral platform articular surface at 2 days and 6 months after surgery were (0.8±0.1) and (0.9±0.1) mm in fracture line group, which were lower than those in fenestration group (0.9±0.1) and (1.1±0.1) mm, respectively (P<0.05). After 2 days and 6 months, , PSA in fracture line group were (9.4±1.5) ° and (10.1±1.9) °, respectively, which were lower than those in fenestration group (10.5±1.5) ° and (11.3±1.9) ° (P<0.05). Rasmussen anatomical scores in fracture line group at 2 days and 6 months were 16(16, 18) and 16(14, 16) points, respectively, which were better than those in fenestrated group (16, 16) and 14(14, 16) points (P< 0.05). The collapse depth, PSA and Rasmussen anatomical score between two groups were better than those before surgery (P<0.05). There was no significant difference in HSS score between two groups at 2 days after surgery (P>0.05). At six months after surgery, HSS score in fracture line group (86.7±3.6) was higher than that in fenestration group (84.1±3.91) (P<0.05). HSS score at 6 months after surgery was better than that at 2 days after surgery (P<0.05). CONCLUSION Both anterior tibial plateau fracture line and anterior tibial fenestration could be used to treat anterolateral tibial plateau column fracture with posterior lateral column collapse. Compared with fenestration group, transfracture line group had advantages of less intraoperative bone grafting, shorter operative time, shorter fracture healing time, better articular surface reduction effect and better knee functional recovery.

Andrographolide sulfonate (AS) is a sulfonated derivative of andrographolide extracted from Andrographis paniculata (Burm.f.) Nees, and has been approved for several decades in China. The present study aimed to investigate the novel therapeutic application and possible mechanisms of AS in the treatment of rheumatoid arthritis. Results indicated that administration of AS by injection or gavage significantly reduced the paw swelling, improved body weights, and attenuated pathological changes in joints of rats with adjuvant-induced arthritis. Additionally, the levels of tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and IL-1β in the serum and ankle joints were reduced. Bioinformatics analysis, along with the spleen index and measurements of IL-17 and IL-10 levels, suggested a potential relationship between AS and Th17 cells under arthritic conditions. In vitro, AS was shown to block Th17 cell differentiation, as evidenced by the reduced percentages of CD4⁺ IL-17A⁺ T cells and decreased expression levels of RORγt, IL-17A, IL-17F, IL-21, and IL-22, without affecting the cell viability and apoptosis. This effect was attributed to the limited glycolysis, as indicated by metabolomics analysis, reduced glucose uptake, and pH measurements. Further investigation revealed that AS might bind to hexokinase2 (HK2) to down-regulate the protein levels of HK2 but not glyceraldehyde-3-phosphate dehydrogenase (GAPDH) or pyruvate kinase M2 (PKM2), and overexpression of HK2 reversed the inhibition of AS on Th17 cell differentiation. Furthermore, AS impaired the activation of phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT) signals in vivo and in vitro, which was abolished by the addition of lactate. In conclusion, AS significantly improved adjuvant-induced arthritis (AIA) in rats by inhibiting glycolysis-mediated activation of PI3K/AKT to restrain Th17 cell differentiation.

BACKGROUND: The prevalence of hypertension is high among Chinese adults, thus, identifying non-hypertensive individuals at high risk for intervention will help to improve the efficiency of primary prevention strategies. METHODS: The cross-sectional data on 9699 participants aged 20 to 80 years were collected from the China National Health Survey in Gansu and Hebei provinces in 2016 to 2017, and they were nonrandomly split into the training set and validation set based on location. Multivariable logistic regression analysis was performed to develop the diagnostic prediction model, which was presented as a nomogram and a website with risk classification. Predictive performances of the model were evaluated using discrimination and calibration, and were further compared with a previously published model. Decision curve analysis was used to calculate the standardized net benefit for assessing the clinical usefulness of the model. RESULTS: The Lasso regression analysis identified the significant predictors of hypertension in the training set, and a diagnostic model was developed using logistic regression. A nomogram with risk classification was constructed to visualize the model, and a website ( https://chris-yu.shinyapps.io/hypertension_risk_prediction/ ) was developed to calculate the exact probabilities of hypertension. The model showed good discrimination and calibration, with the C-index of 0.789 (95% confidence interval [CI]: 0.768, 0.810) through internal validation and 0.829 (95% CI: 0.816, 0.842) through external validation. Decision curve analysis demonstrated that the model was clinically useful. The model had a higher area under receiver operating characteristic curves in training and validation sets compared with a previously published diagnostic model based on Northern China population. CONCLUSION This study developed and validated a diagnostic model for hypertension prediction in Gansu Province. A nomogram and a website were developed to make the model conveniently used to facilitate the individualized prediction of hypertension in the general population of Han and Yugur.

OBJECTIVE: To study the long-term clinical effect of multicenter multidisciplinary treatment (MDT) in children with renal malignant tumors. METHODS: A retrospective analysis was performed on the medical data of 55 children with renal malignant tumors who were diagnosed and treated with MDT in 3 hospitals in Hunan Province from January 2015 to January 2020, with GD-WT-2010 and CCCG-WT-2016 for treatment regimens. A Kaplan-Meier survival analysis was used to analyze the survival of the children. RESULTS: Of the 55 children, 10 had stage I tumor, 14 had stage Ⅱ tumor, 22 had stage Ⅲ tumor, 7 had stage IV tumor, and 2 had stage V tumor. As for pathological type, 47 had FH type and 8 had UFH type. All children underwent complete tumor resection. Of the 55 children, 14 (25%) received preoperative chemotherapy. All children, except 1 child with renal cell carcinoma, received postoperative chemotherapy. Among the 31 children with indication for radiotherapy, 21 (68%) received postoperative radiotherapy. One child died of postoperative metastasis. The incidence rate of FH-type myelosuppression was 94.4%, and the incidence rate of UFH-type myelosuppression was 100%. The median follow-up time was 21 months and the median survival time was 26 months for all children, with an overall survival rate of 98% and an event-free survival rate of 95%. CONCLUSIONS Multicenter MDT has the advantages of high success rate of operation and good therapeutic effect of chemotherapy in the treatment of children with renal malignant tumors, with myelosuppression as the most common side effects, and radiotherapy is safe and effective with few adverse events. Therefore, MDT has good feasibility, safety, and economy.

A girl, aged 1 year and 9 months, was found to have hypertriglyceridemia in the neonatal period, with unusual facies and signs of dark skin all over the body, disappearance of subcutaneous adipose, acanthosis nigricans of the neck, excessive and thick hair, empty cheeks, muscle hypertrophy of the extremities, hepatomegaly, and neutrophil deficiency. Whole exome sequencing of monogenic disorder revealed a homozygote mutation in the BSCL2 gene, c.974 (exon 7)_c.975 (exon 7) insG. Her parents were heterozygotes for this locus. The girl was diagnosed with congenital generalized lipodystrophy (CGL), but the association between CGL and neutrophil deficiency remained unclear. Triglyceride was maintained at a normal level after the treatment with a low-fat and high-carbohydrate diet, and there were no obvious changes in signs. CGL is a rare autosomal recessive systemic disease manifested as disappearance of systemic subcutaneous adipose, muscle hypertrophy of the extremities, and metabolic disorders in the neonatal period, such as high triglycerides, hyperinsulinemia, and hyperglycemia. About 95% of CGL cases are caused by mutations in the AGPAT2 or BSCL2 gene.

OBJECTIVEThe aim of this study was to investigate the association between urinary cadmium and clinicopathological characteristics of breast cancer.

METHODSThe clinicopathological characteristics of 240 patients with breast cancer were obtained and urine specimens were collected from October 2009 to July 2010. The concentration of urinary cadmium was determined by inductively coupled plasma mass spectrometry (ICP-MS). χ(2) test and Wilcoxon rank sum test were used to analyze whether urinary cadmium is associated with clinicopathological characteristics of breast cancer.

RESULTSThe median concentration of urine cadmium of 240 patients was 1.99 µg/g (25th percentile, 1.32 µg/g; 75th percentile, 2.88 µg/g). HER-2 positive rate, regional/distant metastasis rate, and advanced stage rate in patients with the highest tertile of cadmium concentration were significantly higher than those in the patients with second and lowest Cd tertiles (P = 0.042, P = 0.028 and P = 0.017, respectively), and 28.2% vs. 16.5% for HER-2 and 47.2% vs. 32.0% for regional/distant metastasis, respectively. There were still significant associations between urinary cadmium levels and these clinicopathological parameters after being adjusted in age by unconditional logistic regression model, respectively (P < 0.05).

CONCLUSIONSThe results of this study suggest that urinary cadmium levels are associated with the HER-2 status, regional/distant metastasis status and stages of breast cancer, respectively. Cadmium may induce highly aggressive breast cancer in humans.

OBJECTIVETo study the characteristics of viral spectrum and clinical features of children in pediatric intensive care unit (PICU).

METHODNasopharyngeal aspirate specimens (NPA) from 349 patients(1 from each) and 130 cerebrospinal fluids (CSF) specimens were collected from children who were admitted to the PICU of Second Affiliated Hospital of Shantou University Medical College. Additional 87 NPA specimens were collected from healthy children for routine examination on the physical examination center, and the clinical data were collected. Multiplex PCR was applied to detect 16 kinds of viruses from NPA and CSF. Fluorescence quantitative PCR was applied to detect 13 viruses from CSF and to analyze the clinical data of positive cases.

RESULTThere were 209 samples (59.9%) of the 349 NPA specimens were positive for viruses, which included 117 cases positive for human rhinovirus (HRV), 60 for respiratory syncytial virus (RSV), 20 for influenza virus A (Inf A), 10 for adenovirus (ADV), 6 for parainfluenza virus type 3(PIV-3), 6 for human Boca virus (HBoV), 5 for influenza virus C(Inf C), 4 for parainfluenza virus type 4(PIV-4), 4 for human coronavirus-HKU1/OC43, 3 for influenza virus B (Inf B), 3 for WU Polyomavirus (WUPyV), 2 parainfluenza virus type 1(PIV-1), 2 human metapneumovirus (HMPV) and 1 human coronavirus-NL63/229E. But none from 87 healthy controls were positive for any respiratory virus. Among the 130 CSF specimens, in 58 cases the diagnosis was viral encephalitis. There were 22 samples (37.9%) among the 58 CSF specimens positive for viruses, which included 14 enterovirus (EV), 3 human cytomegalovirus (HCMV), 2 mumps virus, 1 coxsackie virus A16 (Cox-A16), 1 herpes simplex virus (HSV) and 1 human rhinovirus (HRV). The total positive rate was 63.3% (221/349) . Co-infection by at least 2 viral pathogens under study was observed in 45 of the 349 patients (12.9% of the total number of cases, 20.4% of the positives cases). The commonest pathogens in co-infected samples were WUPyV (100%) and HMPV(100%). The positive rate of virus peaked in the first 6 months of life, the rate in boys were higher than in girls and the peak season was summer. The numbers of none serious cases in the virus positive group were less than those in the virus negative group while the numbers of extremely serious cases in the virus positive group were higher than in the virus negative group.

CONCLUSIONViral pathogen is a major cause of infectious disease in pediatric critical illnesses and virus infection may lead to severe illness.
