Objective:To explore the incidence and factors of the influence of preoperative related factors on postoperative orthopedic evaluation, through the evaluation of thoracic shape orthopedic evaluation of children pectus excavatum, during plate implantation after Nuss procedure.Methods:From April 2012 to April 2019, the clinical data were analyzed retrospectively for 159 hospitalized cases of Nuss procedure for pectus excavatum in Xi’an Children’s Hospital.The mean age was(6.8±3.4) years old(3.2-17.0 years old); males 124, females 35; Haller index 4.0±1.0(2.7-7.5); 6 cases(4%) were poor orthopedic evaluation with the thoracic shape, males 5, femal 1; 23 cases (14%) were average satisfied with the thoracic shape, males 16, femals 7; 130 cases (82%)were good orthopedic evaluation with the thoracic, males 103, femals 27. Follow-ups were conducted for at least 2 years, Retrospective analysis of the relationship between postoperative thoracic satisfaction and age, gender, Haller index, how the plates were placed during surgery and symmetry of funnel chest, t test and χ2 test were used for statistical analysis. Results:There were statistically significant differences between thoracic orthopedic evaluation after postoperative and classification of pectus excavatum ( P=0.001), and poor orthopedic evaluation after asymmetric pectus excavatum operationand ; There were no significant differences in gender, Haller index, surgical method and how the plates were placed during surgery( P>0.05). However, it can be seen from the mean and percentage that with the decrease of age, and the increase of Haller index, the orthopedic evaluation gradually becomes worse. Conclusion:According to our single-center study, asymmetric pectus excavatum is a factor for poor orthopedic evaluation during plate implantation after Nuss, especially for young children and children with larger Haller index.

Objective:To evaluate the efficacy and safety of mitoxantrone hydrochloride liposome injection in the treatment of peripheral T-cell lymphoma (PTCL) in a real-world setting.Methods:This was a real-world ambispective cohort study (MOMENT study) (Chinese clinical trial registry number: ChiCTR2200062067). Clinical data were collected from 198 patients who received mitoxantrone hydrochloride liposome injection as monotherapy or combination therapy at 37 hospitals from January 2022 to January 2023, including 166 patients in the retrospective cohort and 32 patients in the prospective cohort; 10 patients in the treatment-na?ve group and 188 patients in the relapsed/refractory group. Clinical characteristics, efficacy and adverse events were summarized, and the overall survival (OS) and progression-free survival (PFS) were analyzed.Results:All 198 patients were treated with mitoxantrone hydrochloride liposome injection for a median of 3 cycles (range 1-7 cycles); 28 cases were treated with mitoxantrone hydrochloride liposome injection as monotherapy, and 170 cases were treated with the combination regimen. Among 188 relapsed/refractory patients, 45 cases (23.9%) were in complete remission (CR), 82 cases (43.6%) were in partial remission (PR), and 28 cases (14.9%) were in disease stabilization (SD), and 33 cases (17.6%) were in disease progression (PD), with an objective remission rate (ORR) of 67.6% (127/188). Among 10 treatment-na?ve patients, 4 cases (40.0%) were in CR, 5 cases (50.0%) were in PR, and 1 case (10.0%) was in PD, with an ORR of 90.0% (9/10). The median follow-up time was 2.9 months (95% CI 2.4-3.7 months), and the median PFS and OS of patients in relapsed/refractory and treatment-na?ve groups were not reached. In relapsed/refractory patients, the difference in ORR between patients with different number of treatment lines of mitoxantrone hydrochloride liposome injection [ORR of the second-line, the third-line and ≥the forth-line treatment was 74.4% (67/90), 73.9% (34/46) and 50.0% (26/52)] was statistically significant ( P = 0.008). Of the 198 PTCL patients, 182 cases (91.9%) experienced at least 1 time of treatment-related adverse events, and the incidence rate of ≥grade 3 adverse events was 66.7% (132/198), which was mainly characterized by hematologic adverse events. The ≥ grade 3 hematologic adverse events mainly included decreased lymphocyte count, decreased neutrophil count, decreased white blood cell count, and anemia; non-hematologic adverse events were mostly grade 1-2, mainly including pigmentation disorders and upper respiratory tract infection. Conclusions:The use of mitoxantrone hydrochloride liposome injection-containing regimen in the treatment of PTCL has definite efficacy and is well tolerated, and it is a new therapeutic option for PTCL patients.

Acetaminophen, also known as N-acetyl-p-aminophenol (APAP), is commonly used as an antipyretic and analgesic agent. APAP overdose can induce hepatic toxicity, known as acetaminophen-induced liver injury (AILI). However, therapeutic doses of APAP can also induce AILI in patients with excessive alcohol intake or who are fasting. Hence, there is a need to understand the potential pathological mechanisms underlying AILI. In this review, we summarize three main mechanisms involved in the pathogenesis of AILI: hepatocyte necrosis, sterile inflammation, and hepatocyte regeneration. The relevant factors are elucidated and discussed. For instance, N-acetyl-p-benzoquinone imine (NAPQI) protein adducts trigger mitochondrial oxidative/nitrosative stress during hepatocyte necrosis, danger-associated molecular patterns (DAMPs) are released to elicit sterile inflammation, and certain growth factors contribute to liver regeneration. Finally, we describe the current potential treatment options for AILI patients and promising novel strategies available to researchers and pharmacists. This review provides a clearer understanding of AILI-related mechanisms to guide drug screening and selection for the clinical treatment of AILI patients in the future.

Objective:To evaluate the efficacy and safety of bendamustine monotherapy in Chinese patients with relapsed/refractory (R/R) B cell non-Hodgkin lymphoma (B-NHL) .Methods:This prospective, multicenter, open label, single-arm, phase Ⅱ study investigated bendamustine’s efficacy and safety in Chinese patients with R/R B-NHL. A total of 78 patients with B-NHL in 11 hospitals in China from March 2012 to December 2016 were included, and their clinical characteristics, efficacy, and survival were analyzed.Results:The median age of all patients was 58 (range, 24-76) years old, and 69 (88.4% ) patients had stage Ⅲ/Ⅳ disease. 61 (78.2% ) patients were refractory to previous treatments. Patients received a median of 4 (range, 1-10) cycles of bendamustine treatment. The overall response rate was 61.5 (95% CI 49.8-72.3) % , the median response duration was 8.3 (95% CI 5.5-14.0) months, and the complete remission (CR) rate was 5.1 (95% CI 1.4-12.6) % . In the full analysis set, median progression-free survival (PFS) and median OS were 8.7 (95% CI 6.7-13.2) months and 25.5 months (95% CI 14.2 months to not reached) , respectively, after a median follow-up of 33.6 (95% CI 17.4-38.8) months. Lymphopenia (74.4% ) , neutropenia (52.6% ) , and leukopenia (39.7% ) , thrombocytopenia (29.5% ) and anemia (15.4% ) were the most common grade 3-4 hematologic adverse events (AE) . The most frequent non-hematologic AEs included nausea (43.6% ) , vomiting (33.3% ) , and anorexia (29.5% ) . Univariate and multivariate analysis showed that <4 cycles of bendamustine treatment was a poor prognostic factor for PFS ( P=0.003) , and failure to accept fludarabine containing regimen was a poor prognostic factor for OS ( P=0.009) . Conclusion:Bendamustine monotherapy has good efficacy and safety in the treatment of patient with R/R B-NHL.

ObjectiveTo analyze the mental health status of non-psychiatric inpatients in a general hospital， and to explore the relevant influencing factors， so as to provide references for the screening of mental health problems and the construction of intervention models among non-psychiatric inpatients. MethodsA cross-sectional study was conducted among 916 non-psychiatric inpatients in a third grade class A general hospital in Guangzhou， and all the inpatients were assessed using Patient Health Questionnaire-9 item （PHQ-9）， Generalized Anxiety Disorder-7 item （GAD-7）， Athens Insomnia Scale （AIS） and Columbia-Suicide Severity Rating Scale （C-SSRS） to detect their depression， anxiety， insomnia and suicide risk status. Thereafter， univariate and multivariate Logistic regression analysis were used to screen the risk factors affecting the mental health of inpatients. ResultsA total of 339 （37.0%） inpatients with positive mental health problems were screened， and the screening results for each dimension revealed 218 cases （23.8%） of depression， 141 cases （15.4%） of anxiety， 257 cases （28.1%） of insomnia， 42 cases （4.6%） of suicidal ideation and 7 cases （0.8%） of suicidal behavior. Binary Logistic regression analysis showed that female （OR=1.379， P<0.05） was a risk factor for positive screening of mental health problems. Ordinal Logistic regression analysis denoted that age above 60 years old （OR=1.542， P<0.05） and singlehood （OR=2.055， P<0.05） were risk factors affecting the severity of depression， while senior high school to junior college education （OR=0.524， P<0.05） was a protective factor of depression， meantime， female （OR=1.472， P<0.05） was a risk factor affecting the severity of insomnia. ConclusionMental health problems are quite common among non-psychiatric inpatients in general hospitals， and are mainly affected by factors such as gender， age， marital status and educational background.

Objective To evaluate the effect on nexible ureteroscope one-step treat and step-by-step treat for impacted upper ureteral calculi. Methods The clinical data of 98 cases of impacted upper ureteral calculi were retrospectivelv analvzed between January 2016 and January 2018. The one-step nexible ureteroscopic lithotripsy was used in 48 cases (observation group), and the step-by-step nexible ureteroscopic lithotripsy was used in 50 cases (control group). During the one-step nexible ureteroscopic lithotripsy, only flexible ureteroscope was used to crush the stone, no matter whether the stone located in the ureter or returned to the renal pelvis. During step-by-step nexible ureteroscopic lithotripsy, the rigid ureteroscopy was firstly used for crushing the stone in the ureter. When the stone returned to the renal pelvis, the rigid ureteroscopy was changed into nexible uretemscope for continuous crushing the stone. Operating time, 2 weeks stone clearance rate and the cases of fever after operation were compared between two groups. Results Compared with that of the control group, the operation time of the observation group was significantly shortened [(38.3 ± 10.5) min vs. (55.1 ± 12.7) min, t=-6.415], and the proportion of postoperative body temperature ≥ 38.5 ℃ was also reduced [(4.2％ (2/48) vs. 22.0％(11/50), χ2=5.276]. The differences between the two groups were statistically significant (P<0.05). Two weeks stone clearance rate was 89.6％(43/48) in observation group and 82.0％(41/50)in control group, and there was no significant difference between two groups (χ2=0.493, P > 0.05). Conclusions Flexible ureteroscope one-step method is a safe and effective alternation for incarcerated upper ureteral calculi.

Objective: To investigate the safety and efficacy of needle-tract assisted standard percutaneous nephrolithotomy (PCNL) for the treatment of complicated upper urinary tract calculi. Methods: The clinical data of 1 562 patients with complicated upper urinary calculi who received standard PCNL from December 2013 to December 2017 at Department of Urology, the First Affiliated Hospital of Xiamen University were retrospectively analyzed. There were large residual stones in 256 patients through B-ultrasound exploration after standard PCNL, could′t be detected with nephoscope in standard PCNL tracts. 16 F mini PCNL tract were established in 120 cases for treatment of residual stones, while needle-tract were established in order to guide nephroscope to find residual stones in 126 cases. Needle-tract were transferred to 16 F mini PCNL tract for treatment of residual stones in 10 patients if these residual stones could′t be detected through needle-tract. Operation time, change of hemoglobin level after operation, incidence of postoperative complications, time of hospitalization and rate of stone clearance were measured in two groups. The statistical methods used included t test, Wilcoxon rank sum test, and χ² test. Results: There were 1 to 3 mini tracts (M(Q_R): 1(1)) established in the mini tracts group and 1 to 7 needle-tracts (M(Q_R): 3(2)) established in the needle-tract group (Z=-10.57, P=0.000). Compared with mini tract group, the operation time ((62.0±18.0) minutes vs. (84.0±15.5) minutes, t=10.242, P=0.000), hospitalization time ((4.40±0.86) days vs. (5.20±0.81) days, t=7.570, P=0.049), hemoglobin dropped ((1.31±0.47) g/L vs. (2.74±0.63) g/L, t=20.12, P=0.000), and incidence of postoperative complications (7.9% (10/126) vs. 19.2% (23/120), χ²=6.674, P=0.01) of needle-tract group were lower, while postoperative stone clearance rate was higher (89.7% vs. 76.7%, χ²=7.497, P=0.006). No perioperative severe complications such as pleural injury, pneumatothorax, perforation of renal, trauma of abdominal organ occurred in two groups. Conclusion Needle-tract assisted standard PCNL for the treatment of complicated upper urinary calculi can significantly improve stone clearance rate, reduce operation time, decrease risk of kidney and surrounding organs damage.

Objective To investigate the application value of the anatomical location of positive nodes (N staging) from TNM staging systems published by American Joint Committee on Cancer (AJCC) (7th edition),number of metastatic lymph nodes (NMLN),lymph node ratio (LNR) and log odds of metastatic lymph nodes (LODDS) as prognostic predictors in advanced gallbladder carcinoma(GBC).Methods The retrospective crosssectional study was conducted.The clinicopathological data of 176 patients who underwent radical resection of advanced GBC in the First Affiliated Hospital of Xi'an Jiaotong University between January 2008 and December 2014 were collected.According to preoperative assessment,intraoperative exploration and frozen section biopsy,staging and surgical procedure were confirmed.Observation indicators and evaluation criteria:(1) surgical and postoperative situations;(2) follow-up and survival situations;(3) N staging related indicators based on TNM staging systems of AJCC (7th edition):LNR =NMLN / total number of lymph node dissection,LODDS =Log (NMLN+0.5) / (total number of lymph node dissection-NMLN+0.5);(4) lymph node staging based on NMLN,LNR and LODDS:LODDS ＜-1.0 as LODDS 1 staging,-1.0 ≤ LODDS ＜ 0 as LODDS 2 staging,LODDS ≥0 as LODDS 3 staging;(5) prognostic comparisons of patients with different lymph node staging;(6) accuracy of 4 different types of lymph node staging predicting the prognosis of patients.Follow-up using outpatient examination and telephone interview was performed to detect postoperative survival up to December 31,2017.Measurement data with normal distribution were represented as x-±s.Measurement data with skewed distribution were described as M (range),and comparisons were done using the nonparametric test.The survival rate was calculated by the Kaplan-Meier method,and the Log-rank test was used for survival comparison.Correlation analysis was done using the Spearman correlation analysis,r ≥ 0.800 as a high correlation,0.500 ≤ r ＜ 0.800 as a moderate correlation and 0.300 ≤ r ＜ 0.500 as a low correlation.The receiver operating characteristic (ROC) curve and area under the curve (AUC) were respectively drawn and calculated based on 4 kinds of binary logistic regression model.Akaike information criterion (AIC) and Harrell concordance index (Harrell c-index) were respectively calculated based on 4 kinds of COX proportional hazard regression model.The larger values of AUC and Harrell c-index caused a smaller value of AIC,but a lymph node staging standard correlated with greater prognostic accuracy.Harrell c-index ＜ 0.50 was no prediction,and 0.50 ≤ Harrell c-index ≤ 1.00 was an obvious prediction.Results (1) Surgical and postoperative situations:176 patients underwent successful radical resection of GBC,including 161 in R0 resection and 15 in R1 resection,99 with D1 lymph node dissection and 77 with D2 lymph node dissection.Of 176 patients,9 with postoperative complications were improved by symptomatic treatment,including 6 with bile leakage,2 with hepatic dysfunction and 1 with intra-abdominal hemorrhage.Results of postoperative pathological examination:total number of lymph node dissection,NMLN and LNR were respectively 6.7±4.4,0 (range,0-12.0) and 0 (range,0-1.00);high-differentiated,moderate-differentiated and low-differentiated tumors

statistically significant difference in LNR and LODDS (Z=-1.492,-1.689,P＞0.05).(4) Lymph node staging based on NMLN,LNR and LODDS:NMLN and LNR as a cut-off point were respectively 4.0 and 0.70,NMLN 1 staging (NMLN=0) was detected in 95 patients,NMLN 2 staging (1.0 ≤ NMLN ≤ 4.0) in 61 patients and NMLN 3 staging (NMLN＞4.0) in 20 patients;LNR 1 staging (LNR=0) was detected in 95 patients,LNR 2 staging (0 ＜ LNR ≤ 0.70) in 58 patients and LNR 3 staging (LNR＞0.70) in 23 patients.LODDS 1,2 and 3 stagings was detected in 61,70 and 45 patients,respectively.The lymph node staging based on NMLN and LNR was significantly correlated with based on N staging of TNM staging systems of AJCC (7th edition) (r =0.949,0.922,P＜0.05);the lymph node staging based on LODDS was moderately correlated with based on N staging of TNM staging systems of AJCC (7th edition) (r =0.758,P＜ 0.05).(5) Prognostic comparisons of patients with different lymph node staging:1-,3-and 5-year overall survival rates were respectively 86.3％,65.3％,52.2％ in N0 staging patients and 44.4％,22.2％,13.3％ in N1 staging patients and 25.0％,5.6％,2.8％ in N2 staging patients,with a statistically significant difference

Objective: To evaluate the efficacy and safety of pegylated recombinant human granulocyte colony-stimulating factor (PEG-rhG-CSF) in prophylaxis neutropenia after chemotherapy in patients with lymphoma. Methods: This was a multicenter, single arm, open, phase Ⅳ clinical trial. Included 410 patients with lymphoma received multiple cycles of chemotherapy and PEG-rhG-CSF was administrated as prophylactic. The primary endpoint was the incidence of Ⅲ/Ⅳ grade neutropenia and febrile neutropenia (FN) after each chemotherapy cycle. Meanwhile the rate of antibiotics application during the whole period of chemotherapy was observed. Results: ①Among the 410 patients, 8 cases (1.95%) were contrary to the selected criteria, 35 cases (8.54%) lost, 19 cases (4.63%) experienced adverse events, 12 cases (2.93%) were eligible for the termination criteria, 15 cases (3.66%) develpoed disease progression or recurrence, thus the rest 321 cases (78.29%) were into the Per Protocol Set. ②During the first to fourth treatment cycles, the incidences of grade Ⅳ neutropenia after prophylactic use of PEG-rhG-CSF were 19.14% (49/256) , 12.5% (32/256) , 12.18% (24/197) , 13.61% (20/147) , respectively. The incidences of FN were 3.52% (9/256) , 0.39% (1/256) , 2.54% (5/197) , 2.04% (3/147) , respectively. After secondary prophylactic use of PEG-rhG-CSF, the incidences of Ⅳ grade neutropenia decreased from 61.54% (40/65) in the screening cycle to 16.92% (11/65) , 18.46% (12/65) and 20.75% (11/53) in 1-3 cycles, respectively. The incidences of FN decreased from 16.92% (11/65) in the screening cycle to 1.54% (1/65) , 4.62% (3/65) , 3.77% (2/53) in 1-3 cycles, respectively. ③The proportion of patients who received antibiotic therapy during the whole period of chemotherapy was 34.39% (141/410) . ④The incidence of adverse events associated with PEG-rhG-CSF was 4.63% (19/410) . The most common adverse events were bone pain[3.90% (16/410) ], fatigue (0.49%) and fever (0.24%) . Conclusion During the chemotherapy in patients with lymphoma, the prophylactic use of PEG-rhG-CSF could effectively reduce the incidences of grade Ⅲ/Ⅳ neutropenia and FN, which ensures that patients with lymphoma receive standard-dose chemotherapy to improve its cure rate.

Objective To investigate the proportion, risk factors and tendency of the change of stones composition in recurrent urolithiasis. Methods One hundred and fifty-six recurrent urolithiasis patients from January 2011 to January 2016 were enrolled. Compositions of initial and recurrent stones were measured by infrared spectrophotometry. Stones types, recurrence interval and recurrence frequency were studied as potential risk factors for composition change. Chi square test and Logistic regression analysis was employed in the statistical analysis. Results Stones composition changed during recurrence in 48 patients (30.8%). 22.8%(18/79) of calcium oxalate stones change to infection stones, and 25.8%(8/31) of infection stones changed to calcium oxalate. Univariate analysis showed the risk ratio of composition change in the patients with recurrence interval of 1- 5 years was 0.529(P = 0.039) , compared with those of less than 1 year or more than 5 years. Logistic regression analysis showed the odds ratio of recurrence interval of 1- 5 years was 0.242 (95%CI: 0.086- 0.718, P = 0.012). Conclusions Stones composition changes in about 30.8% of recurrent urolithiasis. The mutual conversion between calcium oxalate and infection stones is the most common. Recurrence interval is an independent risk factor to predict composition change.
