AIM: To investigate the correlation of serum C-reactive protein(CRP)-to-albumin(ALB)ratio(CAR)and neutrophil-to-lymphocyte count ratio(NLR)with pathological staging and prognosis of retinopathy of prematurity(ROP), and the predictive value of its combined testing for the prognosis of infants.METHODS:Prospective study. A total of 147 children with ROP who were born in our hospital from March 2022 to September 2024 were served as the ROP group, and 100 premature infants without ROP were served as the control group in the same period. Fully automatic biochemical analyzer was used to detect serum CRP and ALB; the flow cytometry nucleic acid fluorescence staining was used to count neutrophils and lymphocytes, and the CAR and NLR were calculated. Spearman correlation was used to analyze the relationship of serum CAR and NLR with ROP staging. Logistic regression was used to analyze the factors affecting the prognosis of children with ROP. ROC curve was drew to analyze the predictive value of serum CAR and NLR for the prognosis of ROP.RESULTS: There was comparability between the ROP group and the control group. The ROP group had significantly higher serum CRP, CAR, neutrophil count, and NLR than the control group, and clearly lower ALB and lymphocyte count than the control group(all P<0.05). Children with stage IV ROP had clearly higher serum CAR and NLR than stages I, II, and III, and the differences among stages I, II, and III were significant(all P<0.05). Serum CAR and NLR were positively correlated with ROP staging(r=0.529, 0.587, all P<0.05), and there was a positive correlation between serum CAR and NLR(r=0.546, P<0.05). The poor prognosis group had clearly higher serum CAR and NLR than good prognosis group(all P<0.001). Elevated serum CAR and NLR were risk factors affecting the prognosis of children with ROP(all P<0.05). The AUC of serum CAR, NLR, and joint detection in predicting the prognosis of ROP children was 0.803, 0.825, and 0.938, respectively. The joint detection showed better predictive performance(Zcombinatoion-CAR=2.637, Zcombinatoion-NLR=2.528, all P<0.05).CONCLUSION:Serum CAR and NLR are elevated in children with ROP, and they are closely related to pathological staging and prognosis. The joint detection has a higher predictive value in evaluating the prognosis of ROP.

Acute myeloid leukemia (AML) is a common malignant disease of the hematological system, with high EVI1 expression accounting for 8%-10% of adult AML. Studies have shown that high EVI1 expression plays an important role in the treatment and prognosis of AML. In recent years, researchers have continuously revealed the structure and role of EVI1, but its mechanism of mediating AML has not been fully clarified. Therefore, systematically exploring the role of EVI1 in AML may provide a useful reference for the precise treatment of AML patients with high EVI1 expression.

Objective:To investigate the clinical efficacy and safety of transurethral flexible ureteroscopy combined with single channel minimally invasive percutaneous nephroscopy in the treatment of complex renal calculi.Methods:A total of 72 patients with complex renal calculi admitted to Beijing Friendship Hospital, Capital Medical University from November 2019 to April 2022 were prospective selected, which were randomly divided into study group and control group by the random number table method, with 36 cases in each group. The control group underwent single channel minimally invasive percutaneous nephrolithotomy, while the study group underwent transurethral flexible ureteroscopy combined with single channel minimally invasive percutaneous nephrolithotomy. The perioperative indexes (operation time, postoperative hospital stay, intraoperative blood loss), stone removal effect, renal function indicators [blood urea nitrogen (BUN), serum creatinine (SCr)] and complication rate were compared between the two groups. Measurement data were expressed as mean ± standard deviation ( ± s), and t-test was used for inter-group comparison. The Chi-square test or Fisher exact probability method were used to compare the count data of two groups. Results:The operation time [(101.05±11.34) min vs (107.84±10.28) min] and postoperative hospital stay [(8.54±3.15) d vs (12.36±4.08) d] in the study group were significantly shorter than those in the control group, and the difference were statistically significant ( P<0.05). The amount of intraoperative bleeding was close to that in the control group, but the difference was not statistically significant ( P>0.05). The primary stone clearance rate and summary stone clearance rate in the study group were 91.67% (33/36) and 100.0% (36/36), respectively, which were significantly higher than 69.44% (25/36) and 83.33% (30/36) in the control group, and the differences were statistically significant ( P<0.05). The postoperative BUN and SCr levels in the study group were (5.24±0.31) mmol/L and (90.65±25.57) μmol/L, respectively, the control group was (7.69±0.78) mmol/L and (131.96±37.80) μmol/L, respectively. BUN and SCr levels in the study group were significantly lower than those in the control group, and the differences were statistically significant ( P<0.05). The total incidence of postoperative complications in the study group was significantly lower than that in the control group (5.56% vs 16.67%), and the difference was statistically significant ( P<0.05). Conclusion:Transurethral flexible ureteroscopy combined with single channel minimally invasive percutaneous nephroscopy is an ideal method for the treatment of complex renal calculi, which has good removal effect, less complications and helps to improve renal function.

【Objective】 To investigate the psychological status of patients with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS), and to analyze the effects of anxiety on the total National Institute of Health Chronic Prostatitis Symptom Index (NIH-CPSI) in patients in Ngari Prefecture of Tibet. 【Methods】 CP/CPPS patients treated during Oct.2019 and Oct.2021 were involved and divided into anxiety group and non-anxiety group. The non-anxiety group received routine drug treatment, while the anxiety group received drugs and psychological intervention. 【Results】 A total of 117 patients were involved, including 68 in the anxiety group and 49 in the non-anxiety group. There were no statistical differences between the two groups in terms of age, body mass index (BMI), marital status, smoking history, and education level (P>0.05). The total NIH-CPSI score in the anxiety group (18.53±3.47) was higher than that in non-anxiety group (15.67±3.33), which was mainly manifested by the increase of pain and decrease of quality of life scores. Further stratification of anxiety level revealed that quality of life score and total NIH-CPSI score increased as anxiety symptoms worsened. After drug treatment, pain and urination symptoms were improved in the non-anxiety group, but the quality of life score and total NIH-CPSI score did not change significantly. After psychological intervention, the anxiety group had lower total NIH-CPSI score and other scores. 【Conclusion】 It is not uncommon for CP/CPPS patients to have a comorbidity of anxiety. The increase in the total NIH-CPSI score is caused by the increase of pain score and decrease of quality of life score. Active psychological intervention can improve anxiety, urinary symptoms, pain symptoms and quality of life.

Objective:To compare the postoperative anorectal and urogenital function in patients undergoing Da Vinci robot vs laparoscopic total mesorectal excision (TME) for middle and low rectal cancer.Methods:A prospective controlled study was conducted to analyze the clinical data of 120 patients with middle and low rectal cancer receiving low anterior resection (Dixon procedure) at the Department of Gastrointestinal Surgery, Guizhou Provincial People's Hospital from Jun 2020 to Oct 2022, including 65 patients in the laparoscopic surgery group and 55 patients in the robotic surgery group.All patients underwent colonoscopy and pelvic MRI, and the distance of the tumor from the anal margin was less than 10 cm.The clinical data of the patients were collected and followed up by questionnaire at 12 months after operation. The anal defecation function was assessed by Wexner constipation score and low anterior resection syndrome scale (LARS).The urinary function was measured by International Prostate Symptom Score (IPSS) and International Advisory Committee on Urinary Incontinence Lower Urinary Tract Symptom Scale (ICIQ-MLUTS/ ICIQ-FluTS).Reproductive function was valued by International Index of Erectile Function (IIEF-5 score) was used for male function and the sexual function index (FIFS-19) for females.Results:The postoperative anal defecation function in robotic group was better than that of the laparoscopic group, and the LARS score was (4.3±2.2) vs. (9.8±1.5), t=9.151, P=0.038.There was no serious urinary dysfunction in neither groups. The robot group had a certain advantage in the protection of male urinary function [ICIQ-MLUTS, (1.8±5.8) vs. (13.8±4.9), t=4.128, P=0.038], while there was no significant difference in the female urinary function between the two groups .ICIQ-FLUTS [(-0.3±1.0) vs. (-0.2±0.9), t=0.015, P=0.844].There was no significant difference in reproductive function between the two groups, IIEF-5 score [(-13.4±2.7) vs. (-11.7±3.4), t=0.35, P=0.615]. FIFS-19 [(-5.2±4.6) vs. (-10.5±6.4), t=4.128, P=0.254]. Conclusions:Compared with laparoscopic surgery, robotic surgery has a better possibility of anal defecation after middle-low rectal cancer surgery. The robotic group has certain advantages in male urinary function protection, and the two surgical methods have similar effects on reproductive function protection.

Objective:To investigate the safety and efficacy of individualized transperineal prostate biopsy based on the segmentation of PI-RADS v2 for mpMRI.Method:The clinical data of patients undergoing prostate biopsy in Beijing Friendship Hospital from December 2018 to November 2021 were analyzed retrospectively . A total of 228 patients with a median age of 65(49-83)years underwent biopsy. There were 102(44.7%) with tPSA <10 ng / ml, 108(47.4%) with tPSA 10-20 ng /ml, and 18(7.9%) with tPSA >20 ng /ml, with the median tPSA of 9.87(4.1-89.0)ng /ml. There were 42(18.4%) cases without MRI results, and 32(14.0%)cases with PI-RADS score of 1-2, 47(20.6%)cases of PI-RADS 3, 66(28.9%)cases of PI-RADS 4 and 41(18.1%)cases of PI-RADS 5, respectively.Transrectal ultrasound-guided transperineal prostate targeted biopsy (TB) and systematic biopsy (SB) were performed under local anesthesia or intravenous anesthesia. SB was performed for those without MRI and PI-RADS score of 1-2 (SB group), and TB and SB were performed for those with PI-RADS score of 3-5 (TB+ SB group). Prostate image under ultrasound was cognitively fused according to PI-RADS v2. One needle per area was distributed in 10 areas of each layer(the transition zone anterior and posterior sectors, the peripheral zone anterior, lateral, and medial sectors or central zone in left and right lobe). For those whose prostate length was less than 3cm, 10 needles were punctured, and two needles were added to each lateral lobe of the apex with a total of 14 needles. For those whose prostate length was from 3 to 6 cm, selected two layers with a total of 20 needles. For those with a length greater than 6cm, selected three layers with a total of 30 needles. If there was a suspicious lesion with PI-RADS score of 3-5, two needles were targeted for each lesion.The detection rate and complication rate of prostate cancer and clinically significant prostate cancer (csPCa) in the overall samples were observed, and the difference of the detection rate of prostate cancer and csPCa between the two groups was compared.Results:Of the 228 cases, there were 46 cases undergoing biopsy of one layer, 148 cases of two layers, and 34 cases of three layers, detecting 131 prostate cancer (PCa) diagnosed by pathology, with a detection rate of 57.5%, including 40 cases (17.5%)of clinically insignificant PCa and 91 cases(39.9%)of csPCa. The detection rate of PCa in TB+ SB group was 61.0%(94/154), which was higher than that in SB group, but there was no significant difference ( P=0.114). However, the detection rate of csPCa in TB + SB group was higher than that in SB group, which was 46.8%(72/154)vs. 25.6%(19/74), respectively ( P=0.002). In the combined TB and SB group (TB + SB group), the detection rate of csPCa by TB was 44.8% (69/154), which was higher than that of 33.8%(52/154)by SB( P=0.047). In the TB+ SB group, 7(4.5%) PCa were missed by SB, which was less than 18 cases (11.7%) missed by TB( P=0.022), but csPCa were missed by SB more than that missed by TB( P<0.001). There were 37 cases suffered from complications, with Clavien Dindo classification grade 1 of 29 cases (12.7%), grade 2 of 7 cases (3.1%), and grade 3 of 1 case(0.4%). Conclusions:Individualized transperineal prostate biopsy based on the segmentation of PI-RADS v2 for mpMRI is safe and reliable. Target biopsy by cognitive fusion can improve the detection rate of significant PCa. Systematic biopsy is also an important and essential supplement, which can detect prostate cancer missed by TB. Combined TB and SB are the best choice.

Objective:To analyze the prognosis and influencing factors of different radiotherapy modes in patients with brain metastases from non-small cell lung cancer (NSCLC), and to explore the best benefit population with radiotherapy boost under different prognostic scores.Methods:634 patients with brain metastasis from NSCLC admitted to the Fourth Hospital of Hebei Medical University from 2013 to 2015 were analyzed retrospectively. According to different radiotherapy modes, they were divided into three groups: no radiotherapy group ( n=330), whole-brain radiotherapy group (WBRT)( n=127) and whole-brain radiotherapy combined with boost group (WBRT+ boost)( n=177). The intracranial progression-free survival (iPFS) and overall survival (OS) were calculated by Kaplan-Meier method. The multivariate prognostic factors were analyzed by the Cox models. Results:The median iPFS and OS of all patients were 6.9 months and 9.0 months, respectively. In the no radiotherapy, WBRT and WBRT+ boost groups, the 1-year iPFS was 15.1%, 16.3% and 40.2%( P=0.002), and the 1-year OS was 33.7%, 38.2% and 48.1%( P<0.001), respectively. Multivariate survival analysis demonstrated that different radiotherapy modes were the independent factors affecting iPFS and OS. Subgroup analysis revealed that for patients with 1-3 brain metastases, the 1-year OS and iPFS in the WBRT+ boost group were better than those of WBRT alone ( P=0.026, P=0.044) when GPA score was 2.5-4.0; the 1-year OS and iPFSin the WBRT+ boost group were better than those of WBRT alone ( P=0.036, P=0.049) when there was no targeted therapy; for patients with ≥4 brain metastases, the 1-year iPFS in the WBRT+ boost group was better than that of WBRT alone ( P=0.019, P=0.012) when GPA score was 2.5-4.0 and there was no targeted therapy. When the GPA score was 0-2 or there was targeted therapy, the 1-year OS and iPFS in the WBRT+ boost group were better than those of WBRT alone, but the difference was not statistically significant (all P>0.05). Conclusions:Radiotherapy can significantly improve the iPFS and OS of NSCLC patients with brain metastases. When the number of brain metastases is 1-3, GPA score is 2.5-4.0 or no targeted therapy, boost may improve the iPFS and OS; when the number of brain metastases is more than 4, GPA score is 2.5-4.0 or no targeted therapy, boost may only bring iPFS benefit; when GPA score is 0-2 or targeted therapy, boost may not benefit significantly.

Objective:To analyze the prognosis and influencing factors of patients with brain metastases from non-small cell lung cancer (NSCLC) treated with different doses of whole brain radiotherapy (WBRT).Methods:A total of 244 NSCLC patients with brain metastases who underwent WBRT in the Fourth Hospital of Hebei Medical University from 2013 to 2015 were analyzed retrospectively. According to different doses of WBRT (EQD 2Gy), they were divided into the 30-39 Gy group ( n= 104) and ≥40 Gy group ( n= 140). The intracranial progression-free survival (iPFS) and overall survival (OS) were compared betweentwo groups. According to the number of brain metastases, GPA score, KPS score, chemotherapy and targeted therapy, the prognosis of different doses of WBRT was further analyzed. Results:The median iPFS and OS of all patients were 6.9 months and 11.8 months, respectively. Univariate survival analysis: the 1-year iPFS and 1-year OS between two groups were 22.5% and 25.4%( P=0.430) and 41.1% and 46.4%( P=0.068), respectively. Multivariate survival analysis: different doses of WBRT were not associated with the improvement of iPFS and OS; independent factors influencing iPFS included local boost, gender, number of brain metastases, chemotherapy and targeted therapy; independent factors influencing OS included gender, number of brain metastases, chemotherapy and targeted therapy. Subgroup analysis: in patients with KPS≥90, the 1-year iPFS and OS of patients with WBRT ≥ 40 Gy were seemingly better than those of their counterparts with 30-39 Gy, but the difference was statistically significant only in OS ( P=0.047), the difference was not statistically significant in iPFS ( P=0.068); in patients with chemotherapy, the 1-year iPFS and OS of patients with WBRT≥40 Gy were better than those of their counterparts with 30-39 Gy ( P=0.017, P=0.012); in patients with targeted therapy, the 1-year iPFS and OS in the WBRT≥40 Gy group were better than those in the 30-39 Gy group ( P=0.012, P=0.045). Conclusions:The 30-39 Gy may be the appropriate dose of WBRT for NSCLC patients with brain metastases. WBRT≥40 Gy does not bring more benefits. WBRT≥40 Gy may benefit NSCLC patients with brain metastases with high KPS score or active systemic therapy.

Objective:To investigate the long-term outcomes of laparoscopic ventral rectopexy (LVR) for obstructive defecation with overt pelvic structural abnormalities.Methods:The retrospective cohort study was conducted. The clinical data of 31 obstructive defecation patients with overt pelvic structural abnormalities who were admitted to the Renji Hospital of Shanghai Jiaotong University School of Medicine from June 2014 to August 2020 were collected. There were 6 males and 25 females, aged 59(range, 32?81)years. All 31 patients underwent LVR through transabdominal approach. Observation indicators: (1) the Cleveland clinic constipation score (CCCS); (2) severity of obstructive defecation; (3) patients assessment of constipation quality of life (PAC-QoL). Follow-up was conducted using telephone interview and outpatient examination up to October 2021. One professional researcher assessed the constipation symptoms and quality of life of patients through outpatient interview or mobile software platform of Questionnaire Star. Measurement data with skewed distribution were represented as M(range), and comparison before and after operation was conducted using the Wilcoxon sign rank test. Results:(1) The CCCS. All 31 patients underwent LVR for the first time and were followed up for 61.8(range, 11.0?87.0)months. The constipation symptoms of the 22 patients were improved. The CCCS of the 31 patients before surgery and at the last follow-up time were 15.8(range, 8.0?26.0) and 10.7(range, 2.0?20.0), respectively, showing a significant difference ( Z=?3.98, P<0.05). (2) Severity of obstructive defecation. The severity scores of frequency of bowel movements, difficult of bowel movements, sensation of incomplete defecation, abdominal distension or pain, time of each bowel movements, daily unsuccessful times of defecation, artificial assisted defecation for the 31 patients were 2.9(range, 1.0?4.0), 3.0(range, 1.0?4.0), 1.9(range, 0?3.0), 0.5(range, 0?3.0), 2.6(range, 2.0?4.0), 2.0(range, 0?4.0), 0.9 (range, 0?2.0) before surgery, versus 1.7(range, 0?4.0), 1.6(range, 0?4.0), 1.2(range, 0?4.0), 0.3(range, 0?3.0), 1.7(range, 0?3.0), 1.4(range, 0?3.0), 0.7(range, 0?2.0) after surgery, respectively. There were significant differences in the frequency of bowel movements, difficult of bowel movements, sensation of in-complete defecation, abdominal distension or pain, time of each bowel movements, daily unsuccessful times of defecation for the 31 patients before and after surgery ( Z=?3.38, ?3.80, ?2.54, ?2.31, ?3.64, ?2.75, P<0.05) and there was no significant difference in the artificial assisted defecation for the 31 patients before and after surgery ( Z=?1.31, P>0.05). (3) PAC-QoL. The score of physical discomfort, satisfaction, worries and concerns, psychological discomfort for the 31 patients were 2.3(range, 1.0?4.0), 3.2(range, 1.0?4.8), 2.2(range, 0.6?4.0), 1.8(range, 0.4?3.9) before surgery, versus 1.6(range, 0?4.0), 2.3(range, 0?4.0), 1.7(range, 0?4.0), 1.3(range, 0?4.0)after surgery, respectively, showing significant differences before and after surgery ( Z=?3.49, ?2.17, ?2.50, ?3.05, P<0.05). Conclusions:The long-term outcomes of LVR for obstructive defecation with overt pelvic structural abnorma-lities are satisfactory. Symptoms as frequency of bowel movements, difficult of bowel movements, sensation of incomplete defecation, abdominal distension or pain, time of each bowel movements and daily unsuccessful times of defecation will be significantly improved after LVR and the constipation quality of life of patients will be improved.

Objective:To evaluate the effect of prophylactic irradiation of internal mammary lymph nodes in patients with breast cancer in this Meta-analysis.Methods:CNKI, Wanfang Medical network, CBM, PubMed, EMBASE and Web of Science were searched by computer. The controlled clinical studies comparing whether or not internal mammary lymph node irradiation as an intervention were included and the quality of the included literature was evaluated according to Newcastle-Ottawa Scale (NOS). RevMan 5.3 software and Stata 14 software were used for Meta-analysis.Results:A total of 11 original articles were included, and 13 181 patients were included for Meta-analysis. There was no statistically significant difference in the overall survival (OS) between patients with and without internal mammary lymph node irradiation ( P=0.490). The subgroup analysis using the date of treatment and the degree of risk in the enrolled population as criteria showed that 5-year OS was significantly increased after internal mammary area irradiation in high-risk stage Ⅱ-Ⅲ patients (N+ , T 3-T 4 stage) with the date of treatment of after 2000( P=0.003, 0.006). Compared with patients without internal mammary area irradiation, internal mammary irradiation significantly increased the 5-year disease-free survival (DFS)( P<0.001). Conclusion:Under the modern radiotherapy technology, internal mammary lymph node irradiation improves the DFS of patients, and may bring OS benefits to high-risk stage Ⅱ-Ⅲ breast cancer patients (N+ , T 3-T 4 stage).
