Objective To investigate the clinical efficacy of percutaneous closure of foramen ovale guided by transthoracic echocardio-graphy with simply delivery sheath.Methods The clinical data of patients with patent foramen ovale underwent interventional closure and percutaneous closure guided by transthoracic echocardiography with simply delivery sheath in our hospital from January 2020 to December 2022 were analyzed retrospectively,the patients were divided into interventional closure group(40 cases)and simply delivery sheath group(39 cases).The operation time,incidence of surgical complications,and surgical success rates of patients in the two groups were compared.The closure effect were evaluated by ultrasound immediately after surgery.All the patients were followed up for 6 months after surgery to evaluate remission of the symptoms.Results The surgical success rate of simply delivery sheath group(100%)was higher than that of interventional closure group(90.0%),with statistically significant difference(P<0.05).The operation time of simply delivery sheath group was longer than that of interventional closure group,with statistically significant difference(P<0.05).One patient in the interventional closure group had small amount of pericardial effusion during the operation.Two patients had decreased blood pressure and slowed heart rate in simply delivery sheath group,and symptoms disappeared after treatment.There was no significant difference in the incidence of complications between the two groups(P>0.05).After 6-month follow-up,all occluders were in good position and no residual leakage was found.The symptoms of headache or dizziness disappeared in 28 patients in interventional closure group,significantly relieved in 8 patients;the symptoms of headache or dizziness disappeared in 30 patients in simply delivery sheath group,and significantly relieved in 9 patients.Conclusion Percutaneous closure for patent foramen ovale under the guidence of transthoracic echocardiography with simply delivery sheath is safe and feasible with satisfactory efficacy and higher successful rate without radiation hazard.It is worthy of clinical promotion.

Construction of Nomogram prediction model of myopia risk and lifestyle among primary school students in Tianjin City / 中国学校卫生

Objective@#To explore the relationship between lifestyle and myopia and construct Nomogram model to predict myopia risk among primary school students in Tianjin, so as to provide a scientific basis for precision myopia prevention and control.@*Methods@#From April to July of 2022, a census method was used to conduct vision testing and lifestyle related questionnaires among 373 180 primary school students in 15 districts of Tianjin. The relationship between lifestyle and myopia was analyzed by the multivariate Logistic regression, and a nomogram prediction model was constructed to predict myopia risk.@*Results@#The detection rate of myopia among primary school students in Tianjin was 37.6%. The results of the multivariate Logistic regression showed that daily outdoor activity time of 1-2 h ( OR =0.94) and >2 h ( OR =0.84), time of using daily electronic devices of >2 h ( OR =1.03), daily paper materials reading and writing time of 1-2 h ( OR =1.02) and >2 h ( OR =1.09), weekly fresh vegetable intake of 2-6 times ( OR =0.93) and ≥7 times ( OR =0.88) were statistically correlated with myopia ( P <0.01). The Nomogram prediction model showed that the factors associated with myopia were grade, family history of myopia, gender, daily outdoor activity time, weekly frequency of fresh vegetable intake, daily paper materials reading and writing time, and time of using daily electronic devices time.@*Conclusions@#The lifestyle of primary school students in Tianjin is associated with myopia. The constructed nomogram model could provide a scientific basis for identifying key intervention populations for myopia prevention and taking targeted prevention and control measures.

Retrospective analysis and comparison of total internal disability preservation technique and standardized reconstruction technique / 中国骨伤

OBJECTIVE@#To investigate the efficacy and clinical results of total internal protection technique in anterior cruciate ligament reconstruction.@*METHODS@#A total of 56 patients undergoing anterior cruciate ligament reconstruction treated from January 2018 to December 2019 were selected. According to the different surgical methods, they were divided into total internal reconstruction group and standard bone tunnel group. There were 21 patients in the total internal reconstruction group, including 15 males and 6 females, aged from 20 to 48 with an average of (35.6±6.7) years old, and 35 patients in the standard tibial tunnel group, including 26 males and 9 females, aged 22 to 51 years old with an average of (33.7±9.6) years old. Preoperative examination of Lachman test was positive, magnetic resonance indicated anterior cruciate ligament rupture. There were no significant differences between the two groups in age, sex, body mass index, time from injury to ACL reconstruction, combined meniscus injury and operation method, operation time, ligament diameter, ligament length and other general information. Postoperative evaluation included operation duration, length and diameter of transplanted tendon after braid. International Knee Documentation Committee (IKDC) score, Lysholm score, Tegner score and perioperative complications 2 years after surgery.@*RESULTS@#Both groups were followed up, ranging from 24 to 30 months with an average of (26.9±3.4) months. Postoperative incision healing was good, and no failure or joint infection occurred at the last follow-up. There was no statistically significant difference between the two groups in IKDC score, Lysholm score and Tegner score before, 1 year and 2 years after surgery. However, IKDC score, Lysholm score and Tegner score at 1 year and 2 years after surgery.@*CONCLUSION@#The same postoperative function and stability of knee joint can be obtained by both the residual whole technique and the standardized reconstruction technique. In the residual whole group, only the semitendinosus muscle is taken, and the femoral thin muscle is retained, with greater tibial bone mass preserved, which is safe and effective in clinical practice.

The association between body mass index and in-hospital major adverse cardiovascular and cerebral events in patients with acute coronary syndrome / 中华心血管病杂志

Objective: To assess the association between body mass index (BMI) and major adverse cardiovascular and cerebrovascular events (MACCE) among patients with acute coronary syndrome (ACS). Methods: This was a multicenter prospective cohort study, which was based on the Improving Care for Cardiovascular Disease in China (CCC) project. The hospitalized patients with ACS aged between 18 and 80 years, registered in CCC project from November 1, 2014 to December 31, 2019 were included. The included patients were categorized into four groups based on their BMI at the time of admission: underweight (BMI<18.5 kg/m2), normal weight (BMI between 18.5 and 24.9 kg/m2), overweight (BMI between 25.0 and 29.9 kg/m2), and obese (BMI≥30.0 kg/m2). Multivariate logistic regression models was used to analyze the relationship between BMI and the risk of in-hospital MACCE. Results: A total of 71 681 ACS inpatients were included in the study. The age was (63.4±14.7) years, and 26.5% (18 979/71 681) were female. And the incidence of MACCE for the underweight, normal weight, overweight, and obese groups were 14.9% (322/2 154), 9.5% (3 997/41 960), 7.9% (1 908/24 140) and 7.0% (240/3 427), respectively (P<0.001). Multivariate logistic regression analysis showed a higher incidence of MACCE in the underweight group compared to the normal weight group (OR=1.30, 95%CI 1.13-1.49, P<0.001), while the overweight and obese groups exhibited no statistically significant difference in the incidence of MACCE compared to the normal weight group (both P>0.05). Conclusion: ACS patients with BMI below normal have a higher risk of in-hospital MACCE, suggesting that BMI may be an indicator for evaluating short-term prognosis in ACS patients.

Advances in the effect of inhibiting complement activation in the treatment of sepsis-associated coagulopathy / 中华危重病急救医学

Sepsis-associated coagulopathy refers to extensive coagulation activation accompanied by a high risk of bleeding and organ failure. In severe cases, it is manifested as disseminated intravascular coagulation (DIC) and leads to multiple organ dysfunction syndrome (MODS). Complement is an important component of the innate immune system and plays an important role in defending against invasion of pathogenic microorganisms. The early pathological process of sepsis involves excessive activation of the complement system, which forms an extremely complex network through interactions with the coagulation, kinin and fibrinolytic system, amplifying and exacerbating the systemic inflammatory response. In recent years, it has been suggested that uncontrolled complement activation system can exacerbate sepsis-associated coagulation dysfunction or even DIC, indicating the potential value of intervening in the complement system in the treatment of septic DIC, and related research progress is reviewed in this article in order to provide new ideas for the discovery of sepsis-associated coagulopathy therapy drugs.

A prospective study of the effect of functional endoscopic sinus surgery on the recovery of olfactory function in patients with chronic rhinosinusitis with nasal polyposis / 临床耳鼻咽喉头颈外科杂志

Objective:To investigate the efficacy of functional endoscopic sinus surgery（FESS） in the treatment of olfactory dysfunction in patients with chronic rhinosinusitis with nasal polyps （CRSwNP） , at the same time, it provides an evidence for the prognosis evaluation of olfaction and the clinical application of oERPs to evaluate the plasticity of olfaction cortex. Methods:From October 2021 to October 2022, 45 patients with CRSwNP who underwent FESS nine-step standardized treatment in our department were recruited as the research subjects, divided into 22 patients with eosinophilic CRSwNP（ECRS）and 23 patients with non-eosinophilic CRSwNP（nECRS）. VAS-olfactory dysfunction （VAS-OD） score, SNOT-22 olfactory score, Sniffin' Sticks test and oERPs collection and processing were performed before the operation. All items were evaluated again 3 months after the operation. Results:VAS-OD and SNOT-22 olfactory score were significantly lower in all CRSwNP patients after the operation than those before the operation[F（1, 43） =357.429, P<0.001; F（1, 43） =185.657, P<0.001], the scores of T, D, I and TDI scores in Sniffin' Sticks test were significantly higher than those before the operation[F（1, 43） =126.302, P<0.001; F（1, 43） =311.301, P<0.001; F（1, 43） =131.401, P<0.001; F（1, 43） =295.885, P<0.001]; The decrease of VAS-OD and SNOT-22 olfactory score in the ECRS group was smaller than that in the nECRS group[F（1, 43） =4.825, P=0.033; F（1, 43） =9.916, P=0.003], T, D and TDI scores were significantly lower in nECRS group than those in nECRS group[F（1, 43） =6.719, P=0.013; F（1, 43） =4.890, P=0.032; F（1, 43） =4.469, P=0.040]; There was a positive correlation between preoperative eosinophil-to-lymphocyte ratio（ELR） and SNOT-22 olfactory score and how much it changes（r=0.455, P=0.002; r=-0.414, P=0.005）, a negative correlation between T, TDI score and how much they change respectively（r=-0.431, P=0.003; r=-0.385, P=0.009; r=-0.383, P=0.010; r=-0.316, P=0.035）. The latency of P3 was significantly shorter after operation than that before operation in all CRSwNP patients[F（1, 14） =24.840, P<0.001], however, the amplitude has no significant surgical effect. Conclusion:FESS could significantly improve the olfactory function of CRSwNP patients, while changes in plasticity may occur in the olfactory cortex. In addition, the preoperative peripheral blood eosinophil granulocyte level can predict the postoperative olfactory improvement.

Multivariate correlation analysis of T1S and C7S / 中国骨伤

OBJECTIVE@#To determine whether C7 angles (C7 slope, C7S) could replace T1 angles (T1 slope, T1S) by correlation analysis of T1S and C7S.@*METHODS@#A total of 442 patients from July 2015 to July 2020 in outpatient and inpatient department were enrolled retrospectively, and 259 patients who could identify the upper endplate of T1 were screened out . Of them, there were 145 males and 114 females, aged from 20 to 83 years old with an average of (58.6±11.2) years, including 163 patients with cervical spine surgery and 96 non-surgical patients. Patients were stratified by sex, age, cervical kyphosis, cervical alignment imbalance, and cervical spine surgery. These 259 patients included 145 cases in the male group, 114 cases in the female group;76 cases in the youth group (<40 years old), 109 cases in the middle-aged group (40 to 60 years old), and 74 cases in the elderly group(>60 years old); 92 cases in the cervical kyphosis group, 167 cases in the non-kyphosis group;51 cases in the cervical sequence imbalance group, 208 cases in the non-imbalance group;163 cases in the cervical surgery group, 96 cases in the non-operation group. The correlations of C7S and T1S in various modalities groups were analyzed.@*RESULTS@#Of 442 patients, the recognition rate of upper endplate of T1 was 58.6%(259/442), and that of C7 was 90.7%. The mean T1S and C7S of the 259 patients were (24.5±8.0)° [(25.9±7.7)° in the male group and (23.7±6.9)° in the female group] and (20.8±7.3)° [(22.5±7.5)° in the male group and(19.7±5.8)° in the female group], respectively. The total correlation coefficient between C7S and T1S was r=0.89, R2=0.79, and the linear regression equation was T1S=0.91×C7S+4.35. In the above general information and the grouping of deformity factors, T1S was highly correlated with C7S(r value 0.85 to 0.92, P<0.05).@*CONCLUSION@#There is a high correlation between T1S and C7S in different factor groups. For cases where T1S cannot be measured, C7S can be used to provide guidance and reference for evaluating the sagittal balance of the spine, analyzing the condition, and formulating surgical plans.

Effects of delayed ureteral stents removal during the COVID-19 pandemic on the quality of life and psychological status of postoperative patients with urinary calculi / 北京大学学报(医学版)

OBJECTIVE@#To explore the impacts of delayed ureteral stent removal on the quality of life (QoL) and mental health of urinary calculi postoperative patients due to the corona virus disease 2019(COVID-19) pandemic.@*METHODS@#The demographic and clinical data of patients with ureteral stent placement after urinary endoscopic lithotripsy and returned to Peking University People's Hospital for stent removal from December 2019 to June 2020 were collected. Ureteral stent symptoms questionnaire (USSQ) score and the outcome 20-item self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were collected to estimate the QoL and mental status. The USSQ consisted of 44 questions in 6 domains (including urinary symptom, physical pain, general health, work performance, sexual function, and ureteral stent related infection). For most questions in each domain, its score was a five-point Likert-type scale from 1 to 5, and a small proportion of questions was quantified by 1 to 4 or 1 to 7 scale. SAS and SDS both contained 20 questions used to assess a patient's level of anxiety and depression. Its scoring for each item was on a four-point Likert-type scale from 1 to 4. A total score (ranging from 20 to 80) was the main statistical indicator. The level of clinical anxiety and depression was quantified by using standard scores (total score multiplied by 1.25 to produce integers). And the multi-group structural equation model was constructed by analysis of moment structure (AMOS) analysis.@*RESULTS@#Overall, 71 patients were enrolled for analysis. It was found that the median duration of ureteral stent time differed significantly between the control and delayed groups for 32 (30, 33) d and 94.5 (88, 103) d, respectively. The delayed group resulted in higher scores in the USSQ multidimensional, which included urinary symptoms, general health, work performance and ureteral stent related infections. Anxiety and depression were also significantly serious in the delayed group than in the control group. A longer indwelling time of a ureteral stent could exacerbate the effects of urinary symptoms and physical pain on work performance (P=0.029 < 0.05). Among them, the patients with severe urinary symptoms leading to poor work performance were most significantly affected by prolonged ureteral stent duration time (CR=2.619>1.96).@*CONCLUSION@#Patients with delayed ureteral stent removal due to the COVID-19 had resulted in worse QoL and mental status. Stents related symptoms are more severe in patients with higher anxiety and depression degree during COVID-19. To improve the QoL and mental health of patients after urinary calculi surgery during COVID-19, it is still not recommended to prolong the stent duration time or corresponding intervention measures should be taken.

Choice of medical treatment for renal colic: A survey of Chinese urologists / 北京大学学报(医学版)

OBJECTIVE@#To investigate the status quo of recognition and management of renal colic among urological surgeons in China.@*METHODS@#From November 2021 to March 2022, 725 urological surgeons in China were surveyed in the form of a questionnaire, including their province, hospital grade, professional title, the number of patients with renal colic treated per week, the preferred drugs and the cognition of the disease. This study was approved by the Medical Ethics Committee of Peking University People's Hospital, and all respondents completed informed consent online.@*RESULTS@#During November 2021 and March 2022, urological surgeons across China were surveyed in the form of a questionnaire, and the reliability and validity of the questionnaire were verified before the study was carried out. In the study, 720 valid questionnaires were collected (accounting for 99.31% of the total number), in which 42.4% of the doctors' preferred drugs were non-steroidal anti-inflammatory drugs (NSAIDs), and 40.0% of the doctors' preferred antispasmodic drugs. Opioids were the first choice of 11.0% of the physicians and other treatments were preferred by 6.6% of physicians. In addition, 61.1% of the doctors thought that the mechanism of renal colic was elevated prostaglandin, 32.2% thought it was ureteral spasm, 5.0% thought it was calculi irritation, and 1.7% thought the mechanism was unclear. The doctor of the cognition of the generation mechanism of renal colic pain had a significant influence on the preferred treatment option (χ2=54.399, P < 0.001) that the "elevated prostaglandins" doctor more often preferred NSAIDs than the doctor who thought cramps and ureter stones caused renal colic (51.6% vs. 28.0%, χ2=34.356, P < 0.001;51.6% vs. 19.4%, χ2=13.759, P < 0.001). In addition, hospital class, physician title, and the number of weekly consultations by physicians influenced the choice of medications for renal colic (P < 0.05), tertiary hospitals, middle and senior professional titles and weekly patients with renal colic > 8 cases generally preferred NSAIDs.@*CONCLUSION@#There are deficiencies in the cognition and drug treatment of renal colic among urological surgeons in China. The choice of the preferred drug was related to the doctor's cognition of the disease, the grade of the hospital, the doctor's professional title and the weekly treatment volume.

Short-term efficacy and safety of Donafenib as postoperative adjuvant therapy for patients with high risk of recurrence after radical resection of hepatocellular carcinoma: a multicenter retrospective study / 中华消化外科杂志

Objective:To investigate the short-term efficacy and safety of Donafenib as postoperative adjuvant therapy for patients with high risk of recurrence after radical resection of hepatocellular carcinoma (HCC).Methods:The propensity score matching (PSM) and retrospective cohort study was conducted. The clinicopathological data of 157 HCC patients with high risk of recurrence after radical resection who were admitted to 6 medical centers, including The First Affiliated Hospital of Nanjing Medical University et al, from June 2021 to February 2023 were collected. There were 128 males and 29 females, aged (59±10)years. Of 157 patients, 101 cases undergoing Donafenib as postoperative adjuvant therapy were divided into the the Donafenib group, and 56 cases under-going no systemic postoperative adjuvant therapy were divided into the control group. Observation indicators: (1) PSM and comparison of general data of patients between the two groups after matching; (2) postoperative treatment; (3) follow-up and survival of patients; (4) analysis of risk factors affecting recurrence-free survival of patients. PSM was done based on the principle of optimal perfect matching, with the clamp value of 0.5, and the Donafenib group and the control group were matched at a ratio of 1.25∶1. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers and/or percentages, and comparison between groups was conducted using the chi-square test. Comparison of ordinal data between groups was conducted using the Kruskal-Wallis H test. The Kaplan-Meier method was used to calculate survival rates and draw survival curves, and the Log-Rank test was used for survival analysis. The COX proportional hazard model was used for univariate and multivariate analyses. Results:(1) PSM and comparison of general data of patients between the two groups after matching. Of 157 patients, 126 cases were successfully matched, including 70 cases in the Donafenib group and 56 cases in the control group, respectively. The elimination of tumor number confounding bias ensured comparability between the two groups after PSM. (2) Postoperative treatment. After PSM, of 70 patients in the Donafenib group, there were 23 cases receiving Donafenib monotherapy, 26 cases combined with transcatheter arterial chemoembolization (TACE), 14 cases combined with immunotherapy, and 7 cases combined with TACE+immunotherapy. Of 56 patients in the control group, there were 37 cases receiving postoperative follow-up alone and 19 cases combined with TACE. (3) Follow-up and survival of patients. All 157 patients were followed up, and the follow-up time of the 101 patients in Donafenib group and the 56 patients in control group were 10.1(range, 6.3-14.6)months and 22.2(range, 15.1-25.5)months, respectively. During the follow-up period, 70 patients in the Donafenib group experienced treatment-related adverse reactions, inclu-ding 8 cases of grade 3 adverse reactions, 23 cases of grade 2 and 39 cases of grade 1 adverse reactions, respectively. After PSM, the postoperative 12-, 18-month recurrence-free survival rates were 83.7%, 83.7% in the 70 patients of Donafenib group and 67.8%, 58.9% in the 56 patients of control group, respectively, showing a significant difference in the postoperative recurrence-free survival time between the two groups ( hazard ratio=0.395, 95% confidence interval as 0.176-0.888, P<0.05). (4) Analysis of risk factors affecting recurrence free survival of patients. Results of multivariate ana-lysis showed that microvascular invasion, vascular thrombus, clinical stage as ⅢA were independent risk factors affecting recurrence-free survival in patients with high risk of recurrence after radical resection of HCC ( hazard ratio=2.181, 2.612, 2.612, 95% confidence interval as 1.028-4.629, 1.128-6.047, 1.128-6.047, P<0.05), Donafenib as postoperative adjuvant therapy was an independent protective factor affecting recurrence-free survival in patients with high risk of recurrence after radical resection of HCC ( hazard ratio=0.457, 95% confidence interval as 0.227-0.920, P<0.05). Results of further analysis showed that after PSM, there were significant differences in the postoperative recurrence-free survival time in patients with different clinical factors, including male, age ≥60 years, tumor diameter >5 cm, positive microvascular invasion, positive hepatitis B virus infection, alpha fetoprotein <200 μg/L, between the Donafenib group and the control group ( hazard ratio=0.283, 0.202, 0.174, 0.345, 0.273, 0.180, 95% confidence interval as 0.114-0.707, 0.044-0.937, 0.038-0.794, 0.128-0.929, 0.091-0.819, 0.052-0.620, P<0.05). Conclusion:Donafenib as postoperative adjuvant therapy can effectively reduce the short-term recurrence rate in patients with high risk of recurrence after radical resection of HCC, with good safety and tolerance.

Clinical value of a cuproptosis-related differential long non-coding RNA scoring formula in clear cell renal cell carcinoma / 肿瘤研究与临床

Objective:To investigate the value of a cuproptosis-related differential long non-coding RNA (lncRNA) scoring formula related to the prognosis of clear cell renal cell carcinoma (ccRCC) patients in the clinical diagnosis, prognosis prediction and treatment options based on bioinformatics.Methods:Gene matrix and clinical data of ccRCC patients were obtained from the Cancer Genome Atlas (TCGA) database (update to 29 March, 2022). The expression data of 539 ccRCC tissues and 72 paracancerous normal tissues were collected from gene matrix; the data of 530 ccRCC were collected from clinical data. Pearson correlation analysis, Wilcoxon signed rank test and univariate Cox proportional risk model were used to analyze the screened cuproptosis-related differential lncRNA related to the prognosis. R software was used to randomly divide 530 ccRCC patients with survival data into training set (266 cases) and validation set (264 cases) according to approximate 1∶1 ratio. LASSO regression analysis was used to construct a cuproptosis-related differential lncRNA scoring formula and cross-validation was performed. Receiver operating characteristic (ROC) curve analysis was used to evaluate the specificity and sensitivity of cuproptosis-related differential lncRNA scoring formula, and the area of the curve (AUC) was calculated. According to the median risk value, all patients were divided into the low-risk group and high-risk group; Kaplan-Meier method was used to analyze the difference in the overall survival (OS) of patients in the low-risk group and high-risk group. T test was used to detect the differences in the risk value of patients with different clinicopathological characteristics. R package rms was used to construct the nomogram for predicting 1-year, 3-year, 5-year OS rates of ccRCC patients, R package pRRophetic was used to predict the half-inhibitory concentration ( IC50) of common targeted drugs such as sorafenib and sunitinib in clinical treatment of ccRCC patients, and IC50 value of patients in low-risk group and high-risk group was compared by using Wilcoxon signed rank test. Tissue samples of 20 ccRCC patients who underwent radical nephrectomy and were diagnosed with pathology and the matched paracancerous normal tissues were collected from the First Hospital of Shanxi Medical University between June 2021 and December 2021. Real-time fluorescence quantitative polymerase chain reaction (qRT-PCR) was used to detect the expression of key lncRNA in ccRCC tissues. Results:Based on the expression matrix of 10 cuproptosis genes (FDX1, LIAS, LIPT1, DLD, DLAT, PDHA1, PDHB, MTF1, GLS, CDKN2A) of ccRCC patients in TCGA database, 153 cuproptosis-related differential lncRNA related to the prognosis were identified. According to LASSO regression analysis, a scoring formula of 4 cuproptosis-related differential lncRNA related to the prognosis was obtained, risk value was calculated as 0.020×AC015912.3+0.011×AC026401.3+0.063×AC103706.1+(-0.076)×EPB41L4A-DT. All patients were divided into high-risk group (≥0.76) and low-risk group (<0.76) based on the median value (0.76). ROC curve analysis showed that the scoring formula had good prediction accuracy in 1-year, 3-year, 5-year OS rates. In training set, validation set, the total cohort, the OS of patients in the high-risk group was worse than that in the low-risk group (all P < 0.001). The age, pathological degree, tumor staging, risk value calculated by cuproptosis-related differential lncRNA were independent influencing factors of OS (all P < 0.001). There were statistically significant differences in the risk value calculated by cuproptosis-related differential lncRNA scoring formula among patients with different pathological degree, tumor staging, T staging, N staging, M staging (all P < 0.01), while there were no statistically significant differences among patients with different gender and age (all P > 0.05). The established nomogram had good prediction accuracy in the 1-year, 3-year, 5-year OS rates. Sunitinib and sirolimus showed higher sensitivity in the high-risk group; axitinib, sorafenib and pazopanib showed higher sensitivity in the low-risk group. qRT-PCR results showed that relative expression level of AC015912.3 in ccRCC tissues was up-regulated compared with paracancerous tissues (1.00±0.04 vs. 0.68±0.24, t = 6.37, P < 0.01); the relative expression level of AC026401.3 in ccRCC tissues was up-regulated compared with paracancerous tissues (1.00±0.05 vs. 0.64±0.22, t = 7.29, P < 0.01); the relative expression level of AC103706.1 in ccRCC tissues was up-regulated compared with paracancerous tissues (1.00±0.04 vs. 0.64±0.21, t = 7.49, P < 0.01); the relative expression level of EPB41L4A-DT in ccRCC tissues was up-regulated compared with paracancerous tissues (1.00±0.06 vs. 0.73±0.10, t = 10.68, P < 0.01). Conclusions:Cuproptosis-related differential lncRNA scoring formula based on TCGA database can be used as a new marker for clinical diagnosis and prognosis prediction of ccRCC patients, which can help guide the clinical drug treatment of patients and facilitate accurate diagnosis and treatment.

Research progress on the relationship between Helicobacter pylori infection and the risk of coronary heart disease / 公共卫生与预防医学

Helicobacter pylori (Hp) can be colonized in human gastric mucosa for a long time and is related to various gastrointestinal diseases. At the same time, it may also participate in the occurrence of nervous system, blood system, endocrine and cardiovascular diseases. Coronary heart disease (CHD) is a common clinical cardiovascular system disease, which is characterized by the formation of coronary atherosclerotic plaques and myocardial ischemia damage. In serious cases, it may lead to myocardial infarction and heart failure, with a high risk of death and disability. Hp infection can play an important role in the occurrence and development of CHD through inflammation and immune response, endothelial dysfunction, hyperhomocysteinemia, dyslipidemia, metabolic syndrome, abnormal glucose tolerance, oxidative stress, and cytotoxic factors. In-depth research on the relationship between Hp infection and CHD is not only beneficial to improve clinical treatment regimen for Hp, but also helps to reduce the risk of Hp infection-related CHD, which provides reference for clinical treatment of the disease.

Modified acupuncture at sphenopalatine ganglion for allergic rhinitis: a randomized controlled trial / 中国针灸

OBJECTIVE@#To observe the effect of modified acupuncture at sphenopalatine ganglion for allergic rhinitis (AR).@*METHODS@#A total of 80 patients with AR were randomly divided into an observation group and a control group, 40 cases in each group. In the observation group, modified acupuncture at sphenopalatine ganglion was given, 30 min each time, 2 times a week and with an interval of 3-4 days. In the control group, budesonide nasal spray was given. Both groups were treated for 4 weeks. The total nasal symptom score (TNSS) and total non-nasal symptom score (TNNSS) were observed before treatment, after first treatment, after last treatment and 4 weeks after treatment; the scores of visual analogue scale (VAS) and rhinoconjunctivitis quality of life questionnaire (RQLQ) were observed before treatment, after last treatment and 4 weeks after treatment; the recurrence condition was evaluated 4 weeks after treatment; the clinical efficacy was evaluated after last treatment in the two groups.@*RESULTS@#Compared with before treatment, the total scores and each score of TNSS, TNNSS scores after first treatment, after last treatment and 4 weeks after treatment were decreased in both groups (P<0.01, P<0.05). After first treatment, the total score, stuffy nose score, itchy nose score of TNSS and TNNSS score in the observation group were lower than the control group (P<0.01, P<0.05). After last treatment, the total score, stuffy nose score, itchy nose score of TNSS in the observation group were lower than the control group (P<0.01). Four weeks after treatment, the total score and each score of TNSS, TNNSS score in the observation group were lower than the control group (P<0.01, P<0.05). Compared with before treatment, the scores of VAS and RQLQ after last treatment and 4 weeks after treatment were decreased in both groups (P<0.01), and those in the observation group were lower than the control group (P<0.01). The recurrence rate was 13.5% (5/37) in the observation group, which was lower than 44.8% (13/29) in the control group (P<0.01). The total effective rate was 92.5% (37/40) in the observation group, which was higher than 72.5% (29/40) in the control group (P<0.05).@*CONCLUSION@#Modified acupuncture at sphenopalatine ganglion could effectively improve symptoms and quality of life in patients with AR, and the recurrence rate is lower.

Downregulation of cardiac PIASy inhibits Cx43 SUMOylation and ameliorates ventricular arrhythmias in a rat model of myocardial ischemia/reperfusion injury / 中华医学杂志(英文版)

BACKGROUND@#Dysfunction of the gap junction channel protein connexin 43 (Cx43) contributes to myocardial ischemia/reperfusion (I/R)-induced ventricular arrhythmias. Cx43 can be regulated by small ubiquitin-like modifier (SUMO) modification. Protein inhibitor of activated STAT Y (PIASy) is an E3 SUMO ligase for its target proteins. However, whether Cx43 is a target protein of PIASy and whether Cx43 SUMOylation plays a role in I/R-induced arrhythmias are largely unknown.@*METHODS@#Male Sprague-Dawley rats were infected with PIASy short hairpin ribonucleic acid (shRNA) using recombinant adeno-associated virus subtype 9 (rAAV9). Two weeks later, the rats were subjected to 45 min of left coronary artery occlusion followed by 2 h reperfusion. Electrocardiogram was recorded to assess arrhythmias. Rat ventricular tissues were collected for molecular biological measurements.@*RESULTS@#Following 45 min of ischemia, QRS duration and QTc intervals statistically significantly increased, but these values decreased after transfecting PIASy shRNA. PIASy downregulation ameliorated ventricular arrhythmias induced by myocardial I/R, as evidenced by the decreased incidence of ventricular tachycardia and ventricular fibrillation, and reduced arrythmia score. In addition, myocardial I/R statistically significantly induced PIASy expression and Cx43 SUMOylation, accompanied by reduced Cx43 phosphorylation and plakophilin 2 (PKP2) expression. Moreover, PIASy downregulation remarkably reduced Cx43 SUMOylation, accompanied by increased Cx43 phosphorylation and PKP2 expression after I/R.@*CONCLUSION@#PIASy downregulation inhibited Cx43 SUMOylation and increased PKP2 expression, thereby improving ventricular arrhythmias in ischemic/reperfused rats heart.

Discussion on the location of Dazhui (GV 14) and Yaoyangguan (GV 3) / 中国针灸

Since the anatomical location of acupoints was recorded in The latest Practice of Western Acupuncture in 1915, and Lecture Notes on Advanced Acupuncture in 1931, the Japanese acupuncture works of Chinese translation version, the location of Dazhui (GV 14) (under the spinous process of the 7th cervical vertebra) and Yaoyangguan (GV 3) (under the spinous process of the 4th lumbar vertebra) had rarely been questioned for nearly a century. In order to confirm the above statement, the writers have reviewed ancient literature, combined with the modern anatomical knowledge and searched the evidences from the core arguments of the acupuncture Mingtang chart and the bronze acupuncture statue. It is believed that Dazhui （GV 14） should be positioned under the spinous process of the 1st thoracic vertebra, and Yaoyangguan（GV 3） be under the spinous process of the 5th lumbar vertebra. Accordingly, all of the other acupoints of these meridians should be moved down by 1 vertebra, i.e. those on the governor vessel from Dazhui (GV 14) to Yaoyangguan (GV 3), those on the 1st lateral line of the bladder meridian of foot-taiyang from Dazhu (BL 11) to Baihuanshu (BL 30) and those on the 2nd lateral line of the bladder meridian from Fufen (BL 41) to Zhibian (BL 54).

The value of cardiac MRI in the risk stratification in patients with hypertrophic cardiomyopathy / 中华心血管病杂志

Objective: To explore the value of cardiac magnetic resonance imaging (CMR) in the risk stratification of hypertrophic cardiomyopathy (HCM). Methods: HCM patients who underwent CMR examination in Fuwai Hospital between March 2012 and May 2013 were retrospectively enrolled. Baseline clinical and CMR data were collected and patient follow-up was performed using telephone contact and medical record. The primary composite endpoint was sudden cardiac death (SCD) or and equivalent event. The secondary composite endpoint was all-cause death and heart transplant. Patients were divided into SCD and non-SCD groups. Cox regression was used to explore risk factors of adverse events. Receiver operating characteristic (ROC) curve analysis was used to assess the performance and the optimal cut-off of late gadolinium enhancement percentage (LGE%) for the prediction of endpoints. Kaplan-Meier and log-rank tests were used to compare survival differences between groups. Results: A total of 442 patients were enrolled. Mean age was (48.5±12.4) years and 143(32.4%) were female. At (7.6±2.5) years of follow-up, 30 (6.8%) patients met the primary endpoint including 23 SCD and 7 SCD equivalent events, and 36 (8.1%) patients met the secondary endpoint including 33 all-cause death and 3 heart transplant. In multivariate Cox regression, syncope(HR=4.531, 95%CI 2.033-10.099, P<0.001), LGE% (HR=1.075, 95%CI 1.032-1.120, P=0.001) and left ventricular ejection fraction (LVEF) (HR=0.956, 95%CI 0.923-0.991, P=0.013) were independent risk factors for primary endpoint; Age (HR=1.032, 95%CI 1.001-1.064, P=0.046), atrial fibrillation (HR=2.977, 95%CI 1.446-6.131, P=0.003),LGE% (HR=1.075, 95%CI 1.035-1.116, P<0.001) and LVEF (HR=0.968, 95%CI 0.937-1.000, P=0.047) were independent risk factors for secondary endpoint. ROC curve showed the optimal LGE% cut-offs were 5.1% and 5.8% for the prediction of primary and secondary endpoint, respectively. Patients were further divided into LGE%=0, 0<LGE%<5%, 5%≤LGE%<15% and LGE%≥15% groups. There were significant survival differences between these 4 groups whether for primary endpoint or secondary endpoint (all P<0.001) and the accumulated incidence of primary endpoint was 1.2% (2/161), 2.2% (2/89), 10.5% (16/152) and 25.0% (10/40), respectively. Conclusion: LGE is an independent risk factor for SCD events as well as all-cause death and heart transplant. LGE is of important value in the risk stratification in patients with HCM.

Association of hs-CRP with frailty and its components among the elderly over 65 years old in 9 longevity areas of China / 中华预防医学杂志

Objective: To investigate the association of the levels of high sensitivity C-reactive protein (hs-CRP) with frailty and its components among the elderly over 65 years old in 9 longevity areas of China. Methods: Cross-sectional data from the Health Ageing and Biomarkers Cohort Study (HABCS, 2017-2018) were used and the elderly over 65 years old were included in this study. Through questionnaire interview and physical examination, the information including demographic characteristics, behavior, diet, daily activity, cognitive function, and health status was collected. The association between hs-CRP and frailty and its components in the participants was analyzed by multivariate logistic regression model and restrictive cubic spline. Results: A total of 2 453 participants were finally included, the age was (84.8±19.8) years old. The median hs-CRP level was 1.13 mg/L and the prevalence of frailty was 24.4%. Compared with the low-level group (hs-CRP<1.0 mg/L), the OR (95%CI) value of the high-level group (hs-CRP>3.0 mg/L) was 1.79 (1.35-2.36) mg/L. As for the components, the hs-CRP level was also positively associated with ADL disability, IADL disability, functional limitation and multimorbidity. After adjusting for confounding factors, compared with the low-level group, the OR (95%CI) values of the high-level group for the four components were 1.68 (1.25-2.27), 1.88 (1.42-2.50), 1.68 (1.31-2.14) and 1.39 (1.12-1.72), respectively. Conclusion: There is a positive association between the levels of hs-CRP and the risk of frailty among the elderly over 65 years old in 9 longevity areas of China. The higher hs-CRP level may increase the risk of frailty by elevating the risk of four physical functional disabilities, namely ADL disability, IADL disability, functional limitation and multimorbidity.

Prevalence and treatment of anemia in chronic kidney disease patients based on regional medical big data / 中华流行病学杂志

Objective: To assess the prevalence, risk factors and treatment of anemia in patients with chronic kidney disease (CKD). Methods: A descriptive method was used to analyze the prevalence and treatment of anemia in CKD patients based on regional health data in Yinzhou District of Ningbo during 2012-2018. The multivariate logistic regression analysis was used to identify independent influence factors of anemia in the CKD patients. Results: In 52 619 CKD patients, 15 639 suffered from by anemia (29.72%), in whom 5 461 were men (26.41%) and 10 178 were women (31.87%), and anemia prevalence was higher in women than in men, the difference was significant (P<0.001). The prevalence of anemia increased with stage of CKD (24.77% in stage 1 vs. 69.42% in stage 5, trend χ2 test P<0.001). Multivariate logistic regression analysis revealed that being women (aOR=1.57, 95%CI: 1.50-1.63), CKD stage (stage 2: aOR=1.10, 95%CI: 1.04-1.16;stage 3: aOR=2.28,95%CI: 2.12-2.44;stage 4: aOR=4.49,95%CI :3.79-5.32;stage 5: aOR=6.31,95%CI: 4.74-8.39), age (18-30 years old: aOR=2.40,95%CI: 2.24-2.57, 61-75 years old: aOR=1.35,95%CI:1.28-1.42, ≥76 years old: aOR=2.37,95%CI:2.20-2.55), BMI (<18.5 kg/m2:aOR=1.29,95%CI: 1.18-1.41;23.0-24.9 kg/m2:aOR=0.79,95%CI: 0.75-0.83;≥25.0 kg/m2:aOR=0.70,95%CI: 0.66-0.74), abdominal obesity (aOR=0.91, 95%CI: 0.86-0.96), chronic obstructive pulmonary disease (aOR=1.15, 95%CI: 1.09-1.22), cancer (aOR=3.03, 95%CI: 2.84-3.23), heart failure (aOR=1.44, 95%CI: 1.35-1.54) and myocardial infarction (aOR=1.54, 95%CI:1.16-2.04) were independent risk factors of anemia in CKD patients. Among stage 3-5 CKD patients with anemia, 12.03% received iron therapy, and 4.78% received treatment with erythropoiesis-stimulating agent (ESA) within 12 months after anemia was diagnosed. Conclusions: The prevalence of anemia in CKD patients was high in Yinzhou. However, the treatment rate of iron therapy and ESA were low. More attention should be paid to the anemia management and treatment in CKD patients.
