BACKGROUND:Patients with lumbar disc herniation have different physical deformities due to nucleus pulposus compression and mechanical imbalance. On this basis,Professor Feng Tianyou proposed the "four-step waist type." Professor Feng Wei proposed the objective quantification of three-dimensional scoliosis angle "four-step waist type."OBJECTIVE:To explore the application value of three-dimensional scoliosis angle in evaluating the efficacy of Feng's spinal manipulation in the treatment of patients with lumbar disc herniation.METHODS:A total of 149 hospitalized patients with lumbar disc herniation were enrolled sequentially,including 96 cases of type-Ⅰ/Ⅱ and 55 cases of type-Ⅲ/Ⅳ. The patients were treated with manual therapy for 2 weeks,and 10 healthy volunteers were included as healthy controls. The three-dimensional scoliosis angle was measured using surface topography technology. The difference of three scoliosis angles between patients with type-Ⅰ/Ⅱ and type-Ⅲ/Ⅳ was compared before and after treatment. The difference between patients after treatment and healthy subjects was compered. The difference of three-dimensional scoliosis angles between type-Ⅰ/Ⅱ and type-Ⅲ/Ⅳ after treatment was compared. The intrinsic correlation of each projection plane of three-dimensional scoliosis angle and its correlation with commonly used clinical efficacy scores were explored.RESULTS AND CONCLUSION:(1) The three-dimensional scoliosis angle was significantly different in patients with type-Ⅰ/Ⅱ and type-Ⅲ/Ⅳ before and after treatment (P<0.05). (2) There were significant differences in coronal curve angle and transverse curve angle between patients with type-Ⅰ/Ⅱ,type-Ⅲ/Ⅳ and healthy subjects (P<0.05),but there was no significant difference in sagittal curve angle (P>0.05). (3) There was a correlation between the angles of each section of the three-dimensional angle,and there was a correlation between the three-dimensional angle and the subjective scale. (4) It is indicated that the three-dimensional scoliosis angle can quantitatively evaluate the changes of body deformity before and after treatment. Quantitative indicators can reveal the changes in the patient's condition before and after treatment. The three-dimensional scoliosis angle can reflect the severity of the impact on the patient's living conditions,but the evaluation of scoliosis by a single plane parameter has certain limitations.

Objective:To explore the influencing factors of the therapeutic effect of fiberoptic bronchoscopic alveolar lavage (BAL) in children with severe pneumonia (SP), and the relationship between pulmonary ultrasound parameters and the clearance rates of procalcitonin (PCT) and C-reactive protein (CRP) after treatment.Methods:A total of 284 children with SP admitted to the Yan ′an People′s Hospital from February 2019 to October 2023 were selected as the research subjects; According to the prognosis after 30 days of treatment, they were divided into the good prognosis group ( n=213) and the poor prognosis group ( n=71). The changes of PCT clearance rate, CRP clearance rate and Lung Ultrasound Score (LUS) before and after treatment were compared between the two groups. The correlation between indexes was analyzed using the multiple linear regression (MLR) model. The odds ratio ( OR) of risk factors was calculated using the multivariate logistic regression model. The dose-response relationship was evaluated using the restricted cubic spline (RCS) model. The receiver operating characteristic (ROC) curve was used to analyze the predicting value of each index for poor prognosis after 30 days of treatment. Results:Compared with the good prognosis group, the CRP clearance rate and PCT clearance rate of children in the poor prognosis group were lower 7-14 days after treatment (all P<0.05), and the LUS was higher (all P<0.05). The MLR analysis results showed that LUS was negatively correlated with both CRP clearance rate and PCT clearance rate (all P<0.05), and there was still a significant correlation after adjusting for confounding factors (all P<0.05). The results of logistic regression analysis showed that after excluding confounding factors (Model 4), LUS, PCT clearance rate, and CRP clearance rate were independent risk factors for poor prognosis in children with SP after 30 days of treatment (all P<0.05). The results of RCS analysis showed that there was a nonlinear relationship between the continuous changes of LUS, PCT clearance rate and CRP clearance rate and the risk of poor prognosis in children with SP after 30 days of treatment (nonlinear tests all P<0.001). The combined accuracy of LUS, PCT clearance rate and CRP clearance rate in predicting the poor prognosis of children with SP after 30 days of treatment was relatively high ( P<0.05, AUC>0.75). Conclusions:The clearance rates of LUS and CRP, as well as PCT, are all associated with poor prognosis in children with SP, and the decreased clearance rates of CRP and PCT are independent factors for predicting the increase of LUS. The combined clearance rates of LUS and CRP, as well as PCT, can accurately predict the risk of poor prognosis in children.

Objective:In this study, we aimed to compare the short-term safety of two digestive tract reconstruction techniques, laparoscopic total abdominal overlap anastomosis and laparoscopic-assisted end-to-side anastomosis, following radical resection of Siewert Type II adenocarcinoma of the esophagogastric junction.Methods:In this retrospective cohort study, we analyzed relevant clinical data of 139 patients who had undergone radical surgery for Siewert Type II esophagogastric junction adenocarcinoma. These included 89 patients treated at the First Affiliated Hospital of Air Force Medical University from November 2021 to July 2023, 36 patients treated at the First Affiliated Hospital of Xi'an Jiaotong University from December 2020 to June 2021, and 14 patients treated at the Yuncheng Central Hospital in Shanxi Province from September 2021 to November 2022. The group consisted of 107 men (77.0%) and 32 women (23.0%) of mean age 62.5±9.3 years. Forty-eight patients underwent laparoscopic total abdominal overlap anastomosis (overlap group), and 91 laparoscopic-assisted end-to-side anastomosis (end-to-side group). Clinical data, surgical information, pathological findings, postoperative recovery, and related complications were compared between the two groups.Results:There were no significant differences in general clinical data between the overlap and end-to-side anastomosis groups (all P>0.05), indicating comparability. There was no significant difference in operation time (267.2±60.1 minutes vs. 262.8±70.6 minutes, t=0.370, P=0.712). However, the intraoperative blood loss in the overlap group (100 [50, 100] mL) was significantly lower compared to the end-to-side group (100[50, 175] mL, Z=2.776, P=0.005). Compared to the end-to-side group, longer distances between the tumor and distal resection margin proximal(1.7±1.0 cm vs. 1.3±0.9 cm, t=2.487, P=0.014) and the tumor and distal resection margin (9.5±2.9 cm vs. 7.9±3.5 cm, t=2.667, P=0.009) were achieved in the overlap group. Compared with the end-to-side group, the overlap group achieved significantly earlier postoperative ambulation (1.0 [1.0, 2.0] days vs. 2.0 [1.0, 3.0] days, Z=3.117, P=0.002), earlier time to first drink (4.7±2.6 days vs. 6.2±3.0 days, t=2.851, P=0.005), and earlier time to first meal (6.0±2.7 days vs. 7.1±3.0 days, t=2.170, P=0.032). However, the hospitalization costs were higher in the overlap group (113, 105.5±37, 766.3) yuan vs. (97, 250.2±27, 746.9) yuan; this difference is significant ( t=2.818, P=0.006). There were no significant differences between the two groups in postoperative hospital stay, total number of lymph nodes cleared, or time to first postoperative flatus (all P>0.05). The incidence of surgery-related complications was 22.9%(11/48) in the overlap group and 19.8% (18/91) in the end-to-side group; this difference is not significant (χ2=0.187, P=0.831). Further comparison of complications using the Clavien-Dindo classification also showed no significant differences ( Z=0.406, P=0.685). Conclusions:Both laparoscopic total abdominal overlap anastomosis and laparoscopic-assisted end-to-side anastomosis are feasible for radical surgery for Siewert Type II esophagogastric junction adenocarcinoma. Laparoscopic total abdominal overlap anastomosis achieves longer proximal and distal resection margins and better postoperative recovery; however, end-to-side anastomosis is more cost-effective.

Objective:To deepen understanding of IgG 4-related diseases (RDs), we analyzed the associated lymphocyte subtypes, and explored the pathogenesis and potential immunotherapeutic targets. Methods:Eighty-six patients with IgG 4-RDs were enrolled, and their clinical characteristics, peripheral lymphocyte subtypes, and disease course were analyzed. Results:The mean age of the participants was 36-87(62±11) years; 51 were male (59.3%) and 35 were women (40.7%); and 34.9% had a history of allergy. Follow-up lasted 4.8 (0.4, 14.1) months. The most common symptoms were abdominal pain, and submandibular gland and lacrimal gland swelling (each 20.9%). Sixty-five (75.6%) participants had multiple organ involvement, and the most frequently affected organs were the pancreas (52.3%), submandibular gland (51.2%), and lacrimal gland (34.9%). A high eosinophil count; high IgE, IgG, IgG 1, and IgG 4 concentrations; and low complement C3 and C4 concentrations were present in 18.8% (16/85), 30.0% (24/80), 72.9% (62/85), 58.3% (28/48), 89.5% (77/86), 61.2% (52/85), and 50.0% (42/84), respectively, of the participants. In addition, 64.7% (55/85) were positive for autoantibodies, and the most frequent was anti-nuclear antibody (63.5%). The proportion of CD4 +T lymphocytes increased in 25.7% (9/35) of the participants, which was accompanied by an increase in the ratio of CD4 +/CD8 +T lymphocytes (22.9%, 8/35). Importantly, most participants (90.0%, 18/20) had a high proportion of regulatory T (Treg) cells. High interleukin (IL)-2, IL-6, and IL-10 concentrations were present in 50.0% (11/22), 33.3% (10/30), and 16.7% (5/30), respectively, of the participants. Substantial lymphoplasmacytic infiltration, fibrosis, IgG 4-positive plasma cell infiltration, and lymphoid follicle hyperplasia or ectopic formation were present in 79.2% (42/53), 67.9%(36/53), 35.8%(19/53) and 30.2% (16/53), respectively, of the participants. Fifty-three participants with detailed pathologic data were also further evaluated, of whom 24.5% (13/53), 3.8% (2/53), and 67.9% (36/53) had definite, probable, and possible diagnoses; and 3.8% (2/53) could not be diagnosed. Compared with baseline, the percentage of eosinophils and the IgE, IgG, and IgG 4 concentrations decreased significantly; and the complement C3 and C4 concentrations had increased significantly after 6 months of treatment (all P<0.05). The IgG 4 concentration after 6 months of treatment negatively correlated with that of C4, and positively correlated with the baseline concentration of IgE and the IgG 4/IgG ratio. Conclusion:IgG 4-RDs are a group of diseases characterized by male predisposition; multiple organ involvement; a high eosinophil count; high IgE, IgG, IgG 1, and IgG 4 concentrations; and a low C3 concentration. Peripheral CD4 +T cells and Treg cells are also more abundant. The diseases can be controlled with glucocorticoids and immunosuppressive drugs in the majority of instances. The IgG 4 concentration after 6 months of treatment negatively correlates with the baseline complement C4 concentration and positively correlates with the IgE concentration and IgG 4/IgG ratio, which suggests that IgG 4/IgG, IgE, and complement should be closely monitored to evaluate disease activity and the efficacy of treatment in such patients.

ObjectiveDepression is common in patients with primary biliary cholangitis （PBC）， but the role of depression in disease progression remains unclear. This study aims to investigate the association between depression and treatment response and the impact of depression on liver cirrhosis in PBC patients. MethodsA retrospective analysis was performed for the clinical data of 141 patients with PBC who attended the outpatient service of autoimmune liver diseases in General Hospital of Tianjin Medical University from January 2018 to December 2020 and received standard ursodeoxycholic acid （UDCA） monotherapy for 1 year， and 170 healthy controls， matched for age and sex， who underwent physical examination in Physical Examination Center were enrolled as healthy control group. Patient Health Questionnaire-9 （PHQ-9） was used to evaluate depressive state in the patients with PBC and the healthy controls. The independent-samples t test was used for comparison of normally distributed continuous data between two groups， and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups； the chi-square test was used for comparison of categorical data between two groups. The binary logistic regression model and the decision tree model were used to analyze the influencing factors for liver cirrhosis in patients with PBC， as well as the influence of depression and the HLA-DRB1 gene on liver cirrhosis. The receiver operating characteristic （ROC） curve， the area under the ROC curve （AUC）， and goodness of fit were used to evaluate model performance. All 13 variables were used to establish a classification and regression tree （CART） model， i.e.， age， sex， PHQ-9 score， the DRB1^*03∶01 gene， and the serum levels of alanine aminotransferase， aspartate aminotransferase， alkaline phosphatase （ALP）， gamma-glutamyl transpeptidase （GGT）， total bilirubin， immunoglobulin G， immunoglobulin M （IgM）， C3， and C4. The indications including AUC， sensitivity， and specificity were used to evaluate the performance of CART model in the model cohort. ResultsCompared with the normal control group， the PBC group had a significantly higher proportion of the patients with depression （53.9% vs 15.3%， χ²=57.836， P<0.001）. Compared with the PBC patients without depression， the PBC patients with depression had a significantly poorer response to UDCA treatment （χ²=7.549， P=0.006） and significant increases in the serum levels of ALP （Z=-2.157， P=0.031）， GGT （Z=-2.180， P=0.029）， and IgM （Z=-2.000， P=0.046）. Compared with the PBC patients without depression， the PBC patients carrying the HLA-DRB1^*03∶01 allele had a significant increase in the risk of liver cirrhosis （P<0.001）. The binary logistic regression model analysis showed that PHQ-9 score （OR=1.148， 95%CI： 1.050 — 1.255， P=0.002）， the HLA-DRB1^*03∶01 gene （OR=5.150， 95%CI： 1.362 — 19.478， P=0.016）， age （OR=1.057， 95%CI： 1.009 — 1.106， P=0.018）， and serum ALP level （OR=1.009， 95%CI： 1.001 — 1.017， P=0.020） were independent risk factors for liver cirrhosis in patients with PBC. The decision tree analysis showed that PHQ-9 score ≥3.5 was also a risk factor for liver cirrhosis in PBC patients. ConclusionDepression is associated with poor treatment response in patients with PBC， and it is an independent risk factor for liver cirrhosis in patients with PBC. This study highlights the important clinical significance of the identification and early management of depressive state in patients with PBC.

Tripterygium glycosides tablet(TGT),the classical commercial drug of Tripterygium wilfordii Hook.F.has been effectively used in the treatment of rheumatoid arthritis,nephrotic syndrome,leprosy,Behcet's syndrome,leprosy reaction and autoimmune hepatitis.However,due to its narrow and limited treatment window,TGT-induced organ toxicity(among which liver injury accounts for about 40％of clinical reports)has gained increasing attention.The present study aimed to clarify the cellular and molecular events underlying TGT-induced acute liver injury using single-cell RNA sequencing(scRNA-seq)technology.The TGT-induced acute liver injury mouse model was constructed through short-term TGT exposure and further verified by hematoxylin-eosin staining and liver function-related serum indicators,including alanine aminotransferase,aspartate aminotransferase,alkaline phosphatase and total bilirubin.Using the mouse model,we identified 15 specific subtypes of cells in the liver tissue,including endothelial cells,hepatocytes,cholangiocytes,and hepatic stellate cells.Further analysis indicated that TGT caused a significant inflammatory response in liver endothelial cells at different spatial locations;led to marked inflammatory response,apoptosis and fatty acid metabolism dysfunction in hepatocytes;activated he-patic stellate cells;brought about the activation,inflammation,and phagocytosis of liver capsular macrophages cells;resulted in immune dysfunction of liver lymphocytes;disturbed the intercellular crosstalk in liver microenvironment by regulating various signaling pathways.Thus,these findings elaborate the mechanism underlying TGT-induced acute liver injury,provide new insights into the safe and rational applications in the clinic,and complement the identification of new biomarkers and ther-apeutic targets for liver protection.

Objective:To investigate the short-term efficacy of left-sided three-port total laparoscopic distal gastrectomy (TPTLDG).Methods:The prospective randomized controlled study was conducted. The 68 patients undergoing laparoscopic distal gastrectomy in the First Affiliated Hospital of Air Force Medical University from March 2022 to March 2023 were collected. All patients were randomly assigned to the TPTLDG group with a double number, and to the five-port laparoscopic distal gastrectomy (FPLDG) group with a single number, respectively. Observation indicators: (1) grouping situations of the enrolled patients; (2) comparison of perioperative condition; (3) comparison of complications during postoperative 30 days; (4) comparison of pathological examination. Measure-ment data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test or continuous correction chi-square test. Comparison of ordinal data was analyzed using the non‐parameter rank sum test. Results:(1) Grouping situations of the enrolled patients. A total of 59 patients of gastric cancer were selected for eligibility. There were 40 males and 19 females, aged 59.00(52.00, 67.00)years. The gender (male, female), age, body mass index (BMI), Caprini score (≤2, ≥3), nutritional risk screening 2002 (<3, ≥3), Eastern Coopera-tive Oncology Group performance status (0, 1), preoperative hypersensitive C-reactive protein, preoperative IL-6, preoperative white blood cell count, preoperative albumin were 19, 11, 59.00(51.25,65.25)years, 21.92(20.93,22.73)kg/m 2, 7, 23, 24, 6, 18, 12, 0.78(0.78,1.46)mg/L, 3.07(1.50,10.56)μg/L, 6.07(4.94,7.19)×10 9/L, 44.30(40.83, 46.15) g/L in the 30 patients of TPTLDG group, versus 21, 8, 57.00(51.00, 67.00)years, 21.90(20.95, 23.35)kg/m 2, 11, 18, 24, 5, 17, 12, 1.13(0.78,11.40)mg/L, 5.56(1.88,15.12)μg/L, 5.54(4.71,6.70)×10 9/L, 43.55(40.25,44.88)g/L in the 29 patients of FPLDG group, showing no significant difference in the above indicators between the two groups ( χ2=0.557, Z=-0.444, -0.805, χ2=1.482, 0.074, 0.012, Z=-1.259, -1.262, -0.819, -1.199, P>0.05), confounding bias ensured comparability between the two groups. (2) Comparison of perioperative condition. The length of incision, time to removing drainage tube, IL-6 at postoperative day 3, cost of hospital stay were 6.65(6.48,6.93)cm, 3.00(0,3.00)days, 29.18 (13.67, 43.53)μg/L, 84 164.15(73 084.72, 96 782.14)yuan in the TPTLDG group, versus 8.00(7.50,8.35)cm, 3.00(3.00,4.00)days, 47.56(21.31,85.79)μg/L, 92 120.43(87 069.33, 113 089.74)yuan in the FPLDG group, showing significant differences in the above indicators between the two groups ( Z=-11.065, -2.141, -2.940, -2.220, P<0.05). (3) Comparison of complications during postoperative 30 days. The incidence rate of complications during postoperative 30 days was 30.00%(9/30) and 24.14%(7/29) in the TPTLDG group and FPLDG group, respectively, showing no significant difference between the two groups ( χ2=0.256, P>0.05). (4) Comparison of pathological examination. Cases with pathological N staging as 0 stage, 1 stage, 2 stage, 3 stage were 22, 2, 4, 2 in the TPTLDG group, versus 13, 7, 4, 5 in the FPLDG group, showing a significant difference between the two groups ( Z=-2.021, P<0.05). Conclusion:TPTLDG is safe and feasible for gastric cancer, with a good short-term efficacy.
