Progress on study of factors influencing the prognosis and complications of surgery for discoid meniscus injury in children / 中国骨伤

The discoid meniscus is a common congenital meniscal malformation that is prevalent mainly in Asians and often occurs in the lateral discoid meniscus. Patients with asymptomatic discoid meniscus are usually treated by conservative methods such as observation and injury avoidance, while patients with symptoms and tears need to be treated surgically. Arthroscopic saucerization combined with partial meniscectomy and meniscus repair is the most common surgical approach., and early to mid-term reports are good. The prognostic factors are the patient's age at surgery、follow-up time and type of surgery. Some patients experience complications such as prolonged postoperative knee pain, early osteoarthritis, retears and Osteochondritis dissecans. The incidence of prolonged postoperative knee pain was higher and the incidence of Osteochondritis dissecans was the lowest. Retears of the lateral meniscus is the main reason for reoperation.

Realistic Consideration and Path Choice: Research on the Integration of Epidemic Narrative into College Students’ Ideological and Political Education / 中国医学伦理学

It takes a long time to repair the social damage caused by a major epidemic, which is both a rebuilding of social order and a long process of social psychology. How to reproduce the collective memory of major epidemic events through narration, start from the reality of the epidemic narrative to the should and finally back to practice, and use epidemic narrative as an educational means and carrier in ideological and political education, it will be a beneficial attempt to realize the unification of knowledge and practice in college students’ ideological and political education in the post-epidemic period. To integrate the epidemic narrative into the ideological and political education of college students, it is necessary to adhere to the mainstream ideological direction of the narrative, unblock the narrative channel, reasonably choose the narrative method and optimize the narrative content, adhere to student-oriented, and give full play to the educational function of students’ individual narration.

Data mining and analysis of oxaliplatin-related adverse events of nervous system / 中国药房

OBJECTIVE To provide reference for clinically safe drug use by mining oxaliplatin-related adverse drug events （ADE） of the nervous system. METHODS Oxaliplatin-related neurologic ADE data reported by the FDA adverse event reporting system （FAERS） between January 1st， 2004 and December 31st， 2022 were collected. The reporting odds ratio and proportional reporting ratio were used for data mining. The data were classified statistically by using systematic organ classification， high-level group term （HLGT） and preferred term （PT） in the MedDRA （version 26.0）. RESULTS A total of 7 266 cases of oxaliplatin- related ADE， which were classified as various neurological， were retrieved， and 100 PT were identified. Of these， fifty-seven PT were unspecified adverse reaction signals in the manual. Among these reports， males （46.85%） were more than females （42.98%）， the age of patients was 45-＜75 years （65.22%）， the number of reports was highest in Italy （16.32%）， and the severe type was hospitalization or prolonged hospitalization （38.16%）. The top 5 PT reports in the list of case number were peripheral neuropathy， paresthesia， neurotoxicity， loss of consciousness and dysarthria. The top 5 PT reports in the list of signal intensities were cold- induced paresthesia， neuromuscular rigidity， acute polyneuropathy， neuronal neuropathy， axonal and demyelinating polyneuropathy. A total of 13 HLGT were involved， with neurological diseases （not classified separately） having the highest number of signals （29）. CONCLUSIONS When using oxaliplatin in clinical practice， it is not only necessary to monitor the high incidence of acute and chronic peripheral neuropathy， but also to pay attention to the patient’s consciousness state and neurological symptoms. We should pay attention to the rare types of adverse reactions， such as guillain-barre syndrome， Lhermitte sign， posterior reversible encephalopathy syndrome， and hyperammoniacal encephalopathy， so as to ensure the safety of medication.

OBJECTIVE@#To analyze the result of prenatal diagnosis and outcome of pregnancy for fetuses with rare autosomal trisomies (RATs) suggested by non-invasive prenatal testing (NIPT).@*METHODS@#A total of 69 608 pregnant women who underwent NIPT at Genetics and Prenatal Diagnosis Center of the First Affiliated Hospital of Zhengzhou University from January 2016 to December 2020 were selected as study subjects. The result of prenatal diagnosis and outcome of pregnancy for those with a high risk for RATs were retrospectively analyzed.@*RESULTS@#Among the 69 608 pregnant women, the positive rate of NIPT for high-risk RATs was 0.23% (161/69 608), with trisomy 7 (17.4%, 28/161) and trisomy 8 (12.4%, 20/161) being the most common, and trisomy 17 (0.6%, 1/161) being the rarest. For 98 women who had accepted invasive prenatal diagnosis, 12 fetal chromosomal abnormalities were confirmed, and in 5 cases the results were consistent with those of NIPT, which yielded a positive predictive value of 5.26%. Among the 161 women with a high risk for RATs, 153 (95%) were successfully followed up. 139 fetuses were ultimately born, with only one being clinically abnormal.@*CONCLUSION@#Most women with a high risk for RATs by NIPT have good pregnancy outcomes. Invasive prenatal diagnosis or serial ultrasonography to monitor fetal growth, instead of direct termination of pregnancy, is recommended.

Effect of guarana on lipid metabolism in obese rats: a study based on lipidomics / 中国中药杂志

This study investigated the effect of guarana on plasma lipid metabolites in obese rats and analyzed its mechanism in the treatment of dyslipidemia in obesity. High-fat diet was used to establish obese rat models, and the therapeutic effect of guarana on obese rats was evaluated by measuring body weight, white fat, liver weight, and lipid content, as well as observing liver histomorphology. Lipid metabolites in plasma of rats in each group were detected by UHPLC-Q-TOF-MS lipidomics. The protein expressions of fatty acid synthase, acetyl-CoA carboxylase 1, triglyceride synthesis enzyme, carnitine palmitoyltransferase Ⅰ, and acetyl-coenzyme A acyltransferase 2 in rat liver were detected using Western blot. The results revealed that guarana significantly reduced body weight, white fat, and liver weight of obese rats due to high-fat diet, and alleviated dyslipidemia and liver steatosis. Lipidomics showed that some triglycerides and phospholipids were significantly elevated in the high-fat model group, and part of them was reduced after guarana treatment. Western blot found that guarana inhibited the expression of hepatic fatty acid and triglyceride synthesis-related proteins and increased the expression of fatty acid β-oxidation-related proteins. Abnormalities in triglyceride and phospholipid metabolism are the main characteristics of plasma lipid metabolism in obese rats induced by high-fat diet. Guarana may regulate partial triglyceride and phospholipid metabolism by inhibiting hepatic fatty acid and triglyceride synthesis and increasing fatty acid β-oxidation, thereby improving rat obesity and dyslipidemia.

ObjectiveTo investigate the effect of Qiling Baitouweng Tang （QLBTWT） on proliferation and apoptosis， Janus kinase 2 （JAK2）/signal transducer and activator of transcription 3 （STAT3） signaling pathway and interleukin-10 （IL-10） in diffuse large B-cell lymphoma （DLBCL）. MethodWith human DLBCL cells OCI-LY10 and U2932 as research objects， cell proliferation was detected by cell counting kit-8 （CCK-8） assay. After treatment with 0， 4.6， 9.3， 18.7， 37.5， 75， 150 mg·L-1 QLBTWT for 24 h， the half-inhibitory concentration （IC50） of OCL-LY10 and U2932 cells was calculated to be 9.33， 16.13 mg·L-1， respectively， based on which， 9.5， 19， 38 mg·L-1 QLBTWT were selected for subsequent experiments. After 0， 9.5， 19， 38 mg·L-1 QLBTWT treatment for 24 h， the zymogen activities of Caspase-3， Caspase-8 and Caspase-9 in OCI-LY10 and U2932 cells were detected using corresponding activity assay kits （colorimetric）， and the IL-10 expression was detected by enzyme-linked immuno sorbent assay （ELISA）. The apoptosis rate and cell cycle of OCI-LY10 and U2932 cells treated with different concentrations of QLBTWT for 24 h were detected by flow cytometry. The expressions of apoptosis-related proteins ［B-cell lymphoma 2 （Bcl-2）， Bcl-2-associated X protein （Bax）， cleaved poly adenosine diphosphate ribose polymerase （cleaved PARP）， cleaved Caspase-3］， JAK2， STAT3， phospho-JAK2 （p-JAK2）， phospho-STAT3 （p-STAT3） pathway proteins， and c-Myc protein in OCL-LY10 and U2932 cells after 24 h treatment with 0， 9.5， 19， 38 mg·L-1 QLBTWT were all tested by Western blot. ResultAfter QLBTWT treatment on OCI-LY10 and U2932 cells for 24 h， cell proliferation was inhibited in each QLBTWT group compared with that in the control group （P<0.05， P<0.01）. The zymogens of Caspase-3， Caspase-8 and Caspase-9 were activated （P<0.01）， and there was an increase in cell apoptosis （P<0.05， P<0.01） and cell cycle arrest at Gap phase1 （G1） phase in 9.5， 19 and 38 mg·L-1 QLBTWT group （P<0.05， P<0.01）. After 9.5， 19 and 38 mg·L-1 QLBTWT treatment on OCI-LY10 and U2932 cells for 24 h， the expressions of Bcl-2， p-JAK2 and p-STAT3 proteins were decreased （P<0.01）， and the expressions of Bax， cleaved PARP and cleaved Caspase-3 proteins were increased （P<0.01）， but no significant change was observed in the expressions of JAK2 and STAT3 proteins. Compared with the conditions in the control group， the expressions of c-Myc， p-JAK2， and p-STAT3 proteins were down-regulated in 19 mg·L-1 QLBTWT group and 19 mg·L-1 QLBTWT+10 μg·L-1 IL-10 group （P<0.05， P<0.01）， and up-regulated in 10 μg·L-1 IL-10 group （P<0.05， P<0.01）， while there was no difference in JAK2/STAT3 proteins. ConclusionQLBTWT can inhibit proliferation and induce apoptosis of human DLBCL cells OCI-LY10 and U2932， and the potential mechanism may be related to the regulation of JAK2/STAT3 signaling pathway.

Establishment and data quality control of a multicenter prospective database for prevalence of abdominal complications after gastroenterological surgery / 中华胃肠外科杂志

As the main cause of secondary operation and postoperative death, the incidence of intraperitoneal infectious complications varies significantly in different medical centers in China. Due to the lack of national data, it is not possible to assess and develop appropriate diagnosis and treatment strategies properly. To provide a high-quality data platform for complication registration and clinical research, a multicenter prospective database for the Prevalence of Abdominal Complications After GastroEnterological surgery was established. Based on the Hospital Information System (HIS)of 20 medical centers in China, the electronic case reporting form (e-CRF) listed on the website was used to collect medical information of patients undergoing gastric or colorectal cancer surgery. The data were verified by on-site auditing, and data cleaning was performed by R software. After the data cleaning, the data in the database was checked and evaluated by the principle investigators and data administrators. When all data queries and questions were corrected and answered, the database was locked to establish a multicenter prospective database for postoperative abdominal infectious complications (the PACAGE database). The PACAGE database has rich information resources and high data quality and is a good data platform for complication registration and clinical research.

Clinical characteristics and prognostic factors of patients with Philadelphia-negative myeloproliferative neoplasm accelerated/blast phase / 中华血液学杂志

Objective: To evaluate the clinical characteristics and prognostic factors of patients with Philadelphia-negative myeloproliferative neoplasm-accelerated phase/blast phase (MPN-AP/BP) . Methods: A total of 67 patients with MPN-AP/BP were enrolled from February 2014 to December 2021 at the Institute of Hematology and Blood Diseases Hospital, Chinese Academy of Medical Sciences. Their clinical features and prognostic factors were analyzed retrospectively. Results: ① Sixty-seven patients with MPN-AP/BP with a median age of 60 (range, 33-75) years, including 31 males (46.3% ) and 36 females (53.7% ) , were analyzed. Forty-eight patients progressed from primary myelofibrosis (PMF) , and 19 progressed from other myeloproliferative neoplasms (MPNs) , which included polycythemia vera, essential thrombocythemia, and MPN unclassifiable. Patients who progressed from PMF had higher lactate dehydrogenase (LDH) levels than those who progressed from other MPNs (925.95 vs. 576.2 U/L, P=0.011) , and there were higher proportions of patients who progressed from PMF with splenomegaly (81.4% vs. 57.9% , P=0.05) , a myelofibrosis grade of ≥2 (93.6% vs. 63.2% , P=0.004) , and a shorter duration from diagnosis to the transformation to AP/BP (28.7 vs. 81 months, P=0.001) . ② JAK2V617F, CALR, and MPLW515 were detected in 41 (61.2% ) , 13 (19.4% ) , and 3 (4.5% ) patients, respectively, whereas 10 (14.9% ) patients did not have any driver mutations (triple-negative) . Other than driver mutations, the most frequently mutated genes were ASXL1 (42.2% , n=27) , SRSF2 (25% , n=16) , SETBP1 (22.6% , n=15) , TET2 (20.3% , n=13) , RUNX1 (20.3% , n=13) , and TP53 (17.2% , n=11) . The ASXL1 mutation was more enriched (51.1% vs. 21.1% , P=0.03) , and the median variant allele fraction (VAF) of the SRSF2 mutation (median VAF, 48.8% vs. 39.6% ; P=0.008) was higher in patients who progressed from PMF than those who progressed from other MPNs. ③ In the multivariate analysis, the complex karyotype (hazard ratio, 2.53; 95% confidence interval, 1.06-6.05; P=0.036) was independently associated with worse overall survival (OS) . Patients who received allogeneic stem cell transplantation (allo-HSCT) (median OS, 21.3 vs. 3 months; P=0.05) or acute myeloid leukemia-like (AML-like) therapy (median OS, 13 vs. 3 months; P=0.011) had significantly better OS than those who received supportive therapy. Conclusion: The proportions of patients with PMF-AP/BP with splenomegaly, myelofibrosis grade ≥2, a higher LDH level, and a shorter duration from diagnosis to the transformation to AP/BP were higher than those of patients with other Philadelphia-negative MPN-AP/BP. The complex karyotype was an independent prognostic factor for OS. Compared with supportive therapy, AML-like therapy and allo-HSCT could prolong the OS of patients with MPN-AP/BP.

Metabolomic study on urine of chronic inflammation rats treated with Buyang Huanwu Decoction based on UPLC-Q-TOF-MS / 中国中药杂志

The study investigated the effect of Buyang Huanwu Decoction(BYHWD) on endogenous biomarkers in the urine of rats with chronic inflammation induced by lipopolysaccharide(LPS) using ultra-high performance liquid chromatography-quadrupole-time-of-flight-mass spectrometry(UPLC-Q-TOF-MS), aiming to elucidate the molecular mechanism underlying the therapeutic effect of BYHWD on chronic inflammation from a metabolomics perspective. Male SD rats were randomly divided into a normal group, a model group, and low-, medium-, and high-dose BYHWD groups(7.5, 15, and 30 g·kg~(-1)). The model group and BYHWD groups received tail intravenous injection of LPS(200 μg·kg~(-1)) on the first day of each week, followed by oral administration of BYHWD once a day for four consecutive weeks. Urine samples were collected at the end of the administration period, and UPLC-Q-TOF-MS was used to analyze the metabolic profiles of the rat urine in each group. Multivariate statistical analysis methods such as principal component analysis(PCA), partial least squares-discriminant analysis(PLS-DA), and orthogonal partial least squares-discriminant analysis(OPLS-DA) were used to analyze the effect of BYHWD on endogenous metabolites. One-way ANOVA and variable importance for the projection(VIP) were used to screen for potential biomarkers related to chronic inflammation. The identified biomarkers were subjected to pathway and enrichment analysis using MetaboAnalyst 5.0. A total of 25 potential biomarkers were screened and identified in the rat urine in this experiment. Compared with the normal group, the model group showed significant increases in the levels of 14 substances(P<0.05) and significant decreases in the levels of 11 substances(P<0.05). BYHWD was able to effectively reverse the trend of most endogenous biomarkers. Compared with the model group, BYHWD significantly down-regulated 13 biomarkers(P<0.05) and up-regulated 10 biomarkers(P<0.05). The metabolic products were mainly related to the biosynthesis of pantothenic acid and coenzyme A, tryptophan metabolism, retinol metabolism, and propionate metabolism. BYHWD has therapeutic effect on chronic inflammation induced by LPS, which may be related to its ability to improve the levels of endogenous metabolites, enhance the body's anti-inflammatory and antioxidant capabilities, and restore normal metabolic activity.

Diagnostic and prognostic value of peripheral blood CD4+T lymphocytes for hepatocellular carcinoma recurrence after liver transplantation / 中华检验医学杂志

Objective:To investigate the clinical value of peripheral blood T lymphocytes in the diagnosis and prognosis of patients with hepatocellular carcinoma (HCC) recurrence after liver transplantation.Methods:The clinical and laboratory data of 50 HCC patients, who received liver transplantation and were followed up in the Liver transplantation Center of Beijing Youan Hospital from January 2014 to December 2016, were retrospectively analyzed. The differences on clinical laboratory indicators and five-year survival were compared between HCC recurrence group ( n=29) and non-recurrence group ( n=21). Spearman correlate analysis was used to analyze the correlation between clinical laboratory indicators and HCC recurrence after liver transplantation. Receiver operator characteristic (ROC) curve was used to analyze the diagnostic value of CD4+T lymphocytes in HCC recurrence after liver transplantation. Kaplan-Meier survival curve was used to compare the survival time of patients with different CD4+T lymphocytes levels post liver transplantation. Results:Compared to non-recurrence group, the level of alanine aminotransferase, aspartate aminotransferase, γ-glutamyltransferase, albumin, lymphocytes, alpha-fetoprotein, protein induced by vitamin K deficiency or antagonist-Ⅱ, CD3+, CD4+and CD8+T lymphocytes were significantly different (all P<0.05). The median recurrence time after liver transplantation was 13.0 (6.0, 24.0) months, and the mortality rate was 100%. The 5-year mortality rate was 0 in the non-recurrence group. During 5-year follow-up, the median survival time of patients in the HCC recurrence group was 18.0 (9.0, 36.0) months, which was significantly lower than that of non-recurrence group [60.0 (60.0, 60.0) months, ( P<0.05)]. Compared with non-recurrence group, the CD3+, CD4+, and CD8+T lymphocytes were significantly lower in the recurrence group (all P<0.05). Spearman correlate analysis showed that HCC recurrence after liver transplantation was negatively correlated with the CD3+, CD8+and CD4+T lymphocytes ( r=-0.43, -0.38, -0.44, all P<0.05). ROC analysis showed that CD4+T lymphocytes at cutoff of≤265.50 cells/μl was valuable for the diagnosis of HCC recurrence after liver transplantation (specificity 100%, sensitivity 48.30%). Survival curve analysis showed that the survival time was significantly lower in the CD4≤265.50 cells/μl group [15.0 (10.0, 36.8) months] than that in the CD4>265.50 cells/μl group [53.0 (19.5, 60.0) months] ( P<0.05). Conclusion:There is a significant negative correlation between CD4+T lymphocytes and HCC recurrence after liver transplantation. CD4+T lymphocytes at cutoff value of≤265.50 cells/μl is valuable for the clinical diagnosis and prognosis evaluation of HCC recurrence after liver transplantation.

Objective:To investigate the therapeutic effect of open suture and selective suture in patients with high complexity anal fistula and its effect on anal function and complications.Methods:Prospectively selected 174 patients with high complex anal fistula who were hospitalized in the Anorectal Surgery Department of the Second People′s Hospital of Yibin City from December 2018 to December 2021 as the study subjects, including 138 males and 36 females, aged from 26 to 45 years, with an average of (35.20 ± 8.86) years. According to the admission order of patients, grouped them into single and double numbers, with single numbers being the control group ( n=87) and double numbers being the observation group ( n=87). The control group was treated with traditional incision and thread hanging therapy, while the observation group was treated with selective suture through incision and thread hanging therapy. Compared the surgical time, blood loss, surgical cost, wound healing time, and anal function at 6 months after surgery between the two groups of patients. Compared the treatment effects of two groups of patients at 6 months after surgery. Compared the postoperative complications within 6 months and recurrence within 1 year between the two groups. The measurement data subject to normal distribution were expressed by mean ± standard deviation( ± s). The two groups were compared by independent sample t test, and the count data were compared by Chi-square test. Rank sum test was used for comparison of hierarchical data. Results:The surgical time in the observation group was higher than that in the control group [(44.30 ± 8.11) min vs (42.18 ± 7.25) min, ( t=-2.44, P<0.05], and the surgical cost was higher than that in the control group [(1184.81 ± 372.68) yuan vs (835.28 ± 320.03) yuan, t=-8.75, P<0.001]. There was no statistically significant difference in blood loss data between the two groups [(19.57 ± 6.07) mL vs (18.35 ± 5.25) mL, t=-1.88, P>0.05]. The length of wound healing time in the observation group was lower than that in the control group [(24.18 ± 4.35) d vs (29.35 ± 5.08) d, t=11.09, P<0.001]. The anal function score of the observation group at 6 months after surgery was lower than that of the control group [(4.80 ± 1.21) score vs (6.71 ± 1.35) score, t=14.72, P<0.001]. All patients did not experience any loss of follow-up. In the comparison of treatment effects 6 months after surgery, the observation group had a better efficacy rating than control group ( Z=3.86, P<0.001). At 6 months after surgery, the incidence of complications in the observation group was lower than that in the control group [2.30% (2/87) vs 10.34% (9/87), χ2=4.76, P<0.05]. One year after surgery, the recurrence rate in the observation group was lower than that in the control group [2.30% (2/87) vs 10.34% (9/87), χ2=4.76, P<0.05]. Conclusion:The application of incision and thread-drawing selective suture in the treatment of patients with high complex anal fistula is beneficial to the treatment effect of patients, reduces postoperative complications, and protects the anal function of patients, with good use value.

Evaluation of Renal Impairment in Patients with Diabetic Kidney Disease by Integrated Chinese and Western Medicine / 中国结合医学杂志

OBJECTIVE@#To investigate the factors related to renal impairment in patients with diabetic kidney disease (DKD) from the perspective of integrated Chinese and Western medicine.@*METHODS@#Totally 492 patients with DKD in 8 Chinese hospitals from October 2017 to July 2019 were included. According to Kidney Disease Improving Global Outcomes (KDIGO) staging guidelines, patients were divided into a chronic kidney disease (CKD) 1-3 group and a CKD 4-5 group. Clinical data were collected, and logistic regression was used to analyze the factors related to different CKD stages in DKD patients.@*RESULTS@#Demographically, male was a factor related to increased CKD staging in patients with DKD (OR=3.100, P=0.002). In clinical characteristics, course of diabetes >60 months (OR=3.562, P=0.010), anemia (OR=4.176, P<0.001), hyperuricemia (OR=3.352, P<0.001), massive albuminuria (OR=4.058, P=0.002), atherosclerosis (OR=2.153, P=0.007) and blood deficiency syndrome (OR=1.945, P=0.020) were factors related to increased CKD staging in patients with DKD.@*CONCLUSIONS@#Male, course of diabetes >60 months, anemia, hyperuricemia, massive proteinuria, atherosclerosis, and blood deficiency syndrome might indicate more severe degree of renal function damage in patients with DKD.
