This article discusses the key pathogenesis of atherosclerosis （AS） based on the physiological characteristics and pathological changes of lipids and introduces the therapeutic effect of Zhuyuwan on AS， aiming to provide a theoretical basis for the treatment of cardiovascular diseases from the spleen. As essential substances， lipids have the same essence but different forms. They circulate throughout the body with body fluids under the action of Yang Qi to nourish the nutrient Qi and support the defensive Qi. Lipid metabolism disorder often leads to the obstruction of Qi movement， the accumulation of dampness and turbidity， and the generation of phlegm and blood stasis. It has been proven that the formation of vulnerable plaques in AS is attributed to the interaction of three pathogenic factors： deficiency of healthy Qi， phlegm-turbidity， and collateral stasis. Their pathological essence is closely related to abnormal lipid metabolism. As lipids constitute the thick and dense components of body fluids， their impaired dispersion may lead to phlegm-turbidity and blood stasis， the pathological process of which is predominantly ascribed to the dysfunction of the spleen in distributing essence. Therefore， AS is rooted in spleen-stomach disorder， manifests as plaques formed by pathological product accumulation in vessels， with lipid transport disorder as its core pathogenesis. Specifically speaking， the dysfunction of spleen in transportation with accumulation of dampness-turbidity marks the initial stage， and blood turbidity and coagulation and phlegm-nodules accumulating in vessels represent the intermediate phase. Cold accumulation and stagnated heat transforming into toxins represent the terminal stage. Zhuyuwan， first recorded in Taiping Holy Prescriptions for Universal Relief， contains equal proportions of Coptidis Rhizoma and Evodiae Fructus. Coptidis Rhizoma， bitter and cold， exerts descending and purging actions to assist stomach Qi in lowering turbidity. Evodiae Fructus， pungent-bitter and hot， disperses obstruction and promotes free flow to support spleen Qi in ascending the clear. The compatibility of Coptidis Rhizoma and Evodiae Fructus ascends the clear and descends the turbid to harmonize Yin and Yang， assisting the spleen in distributing essence and resolving lipid accumulation to reduce lipid levels. In terms of the therapeutic mechanism， Zhuyuwan modulates lipid metabolism by correcting immune-inflammation network imbalance， improving gut microbiota composition and metabolism， and enhancing reverse cholesterol transport. By analyzing the pathological characteristics of lipid transport disorder in AS， this study delves into the intrinsic connections between cardiovascular disease and lipid transport disorder， giving novel insights into the prevention and treatment of AS.

Background Work-related musculoskeletal disorders (WMSDs) are considered to be one of the biggest health problems in the workplace, seriously affecting the productivity and quality of life of the working population. Long working hours may associate with WMSDs, and leisure-time physical activity (LTPA) is beneficial for WMSDs. However, the independent and combined effects of these two factors on WMSDs remain poorly understood. Objective To explore the independent and joint relationships between long working hours, leisure time physical activity (LTPA), and WMSDs, and to provide a basis for prevention and intervention of WMSDs. Methods A cross-sectional survey was conducted among 1227 frontline workers from multiple secondary industry companies in Nanchong City in 2023 using cluster random sampling. Demographic characteristics information, weekly working hours, LTPA, personal health behaviors, and occupational factors were collected through questionnaires. The Chinese version of Musculoskeletal Disorders Questionnaire was used to assess WMSDs. χ² test and logistic regression were used to analyze the relationships between long working hours and/or LTPA and WMSDs. Results A total of 1227 workers were surveyed with a mean age of (41.3±9.3) years and 855 (69.7%) were male and 372 (30.3%) were female. Among then, 855 (69.7%) workers reported working >40 h per week, and 254 (20.7%) reported working ≥ 55 h per week; 561 (45.7%) reported no LTPA and 192 (15.6%) reported high LTPA. The overall positive rate of WMSDs was 57.4%. The positive rate of WMSDs was 71.3% in those working ≥55 h per week, which was significantly higher than those in the other groups (51.3%-58.2%, P<0.05). Comparison among the positive rate of WMSDs in the weekly working 41-48 h group (54.4%), the 49-54 h group (58.2%), and the ≤40 h group (51.3%) showed no statistically significant difference (P>0.05). The positive rate of WMSDs was higher in workers with no LTPA (59.0%)/low LTPA (58.9%) than in those with high LTPA (49.0%) (P<0.05). The logistic regression models showed that after adjusting gender, age, work experience, income per month, night shift, industry, prolonged fixed posture, prolonged repetition, smoking and alcohol drinking, compared with weekly working ≤40 h, the risk of WMSDs was higher in those with extra-long working hours (≥55 h·week⁻¹ ) (OR=2.155, 95%CI: 1.504, 3.088), whereas those with high LTPA had a lower risk of WMSDs (OR=0.614, 95% CI: 0.432, 0.874 ). The combination of no LTPA and extra-long working hours (≥55 h·week⁻¹) and low LTPA and extra-long working hours (≥55 h·week⁻¹) showed associations with WMSDs, with 2.360 and 2.049 times higher risk of WMSDs than that of the combination of no LTPA and standard working hours (≤40 h ·week⁻¹) respectively (P<0.05), whereas the combination of high LTPA and long working hours was not observed statistical significance (P>0.05). Conclusion Extra-long working hours and/or LTPA show different associations with the risk of WMSDs. Extra-long working hours are significantly positively associated with the risk of WMSDs, whereas high LTPA is significantly negatively associated with the risk of WMSDs. The combination of extra-long working hours with no or low LTPA is associated with elevated risk of reporting WMSDs, whereas no statistical significance is observed for the high LTPA-long work hours combination.

Objective To observe the value of ultrasonic parameters for predicting whether patients with cesarean scar pregnancy(CSP)would benefit from ultrasound-guided suction curettage alone.Methods Totally 140 CSP patients diagnosed by transvaginal ultrasound and initially treated with ultrasound-guided suction curettage alone were prospectively recruited and categorized into benefited group(n=103)and non-benefited group(n=37)according to bleeding during suction curettage and prognoses.The ultrasonic manifestations of CSP were observed,and the thickness of chorionic villi at the scar,as well as of residual myometrium of the anterior wall in the lower segment of the uterus,also the maximum diameter of the gestational sac were measured and compared between groups,and the parameters with quantitative data being statistically different between groups were converted into categorical predictor through analyzing of the receiver operating characteristic(ROC)curves and the optimal cut-off values.The independent predictors were selected among ultrasonic features and categorical predictor variables being statistically different between groups using multivariate logistic regression,and a combined predicting model was then constructed,and the predicting efficacy of the combined model and each categorical predictor alone was assessed according to the area under curve(AUC)and then were compared.Results Compared with non-benefited group,the gestational weeks in benefited group were smaller(P＜0.05),and the percentages of rich blood supply and the presence of embryos and fetal heartbeats were lower,with thinner chorionic villi at the scar,thicker residual myometrium and smaller maximal diameter of the gestational sac in benefited group(all P＜0.05).ROC curves analyses yielded the best cut-off value for dichotomy of chorionic villi thickness at the scar was 4.7 mm,of residual myometrium thickness was 1.8 mm and of the maximum diameter of the gestational sac was 29 mm,respectively,and then categorical predictor variable were obtained.Multivariate logistic regression showed that the transformed categorical predictors,i.e.the thickness degree of the chorionic villi at the scar,the thickness degree of the residual muscle layer and the size degree of the gestational sac,were all independent predictors of whether CSP patients would benefit from ultrasound-guided suction curettage alone(all P＜0.05).The AUC of the combined predicting model was 0.918,higher than that of each transformed categorical predictor alone(all P＜0.05).Conclusion The thickness of the chorionic villi at the scar ≤4.7 mm,the thickness of the residual muscle layer＞1.8 mm and the maximum diameter of the gestational sac≤29 mm were all independent predictors of CSP patients would benefit from ultrasound-guided suction curettage alone,and the predicting efficacy of the combined model was higher than that of each alone.

Objective To detect the expression levels of tumor necrosis factor alpha induced protein 3(TN-FAIP3)and LINC00887 in clear cell renal cell carcinoma(ccRCC)tissue,and to study their relationship with clinical pathological parameters and prognosis.Methods A total of 101 ccRCC patients admitted to the hospi-tal from January 2013 to October 2018 were selected.The expression levels of TNFAIP3 and LINC00887 were detected in ccRCC cancer tissue and paired adjacent tissues,respectively.The relationship between TNFAIP3 and LINC00887 expression and clinical pathological parameters and prognosis of ccRCC patients was analyzed,and the influencing factors of poor prognosis in ccRCC patients were also analyzed.Spearman correlation coef-ficient was used to analyze the correlation between TNFAIP3 and LINC00887 expression.Results The posi-tive rate of TNFAIP3 expression in ccRCC(37.62％)was significantly lower than that in adjacent tissues(52.48％),and the difference was statistically significant(X2=4.500,P=0.034).The expression level of LINC00887 in ccRCC(1.38±0.61)was significantly higher than that in adjacent tissues(1.03±0.43),and the difference was statistically significant(t=5.396,P＜0.001).The positive rates of TNFAIP3 protein in pa-tients with maximum tumor diameter ≥4.5 cm and TNM stage Ⅲ-Ⅳ were lower than those in patients with maximum tumor diameter＜4.5 cm and TNM stage Ⅰ-Ⅱ,and the differences were statistically significant(P＜0.05).The positive rates of LINC00887 in patients with maximum tumor diameter ≥ 4.5 cm,pathologi-cal grading Ⅲ-Ⅳ,and TNM stage Ⅲ-Ⅳ were higher than those in patients with maximum tumor diameter＜4.5 cm,pathological grading Ⅰ-Ⅱ,and TNM stage Ⅰ-Ⅱ,and the differences were statistically signifi-cant(P＜0.05).Compared with the TNFAIP3 high expression group,the TNFAIP3 low expression group had a poorer prognosis,and the difference was statistically significant(x2=5.118,P=0.024).Compared with the LINC00887 low expression group of,the LINC00887 high expression group had a poorer prognosis,and the difference was statistically significant(x2=4.638,P=0.031).Low expression of TNFAIP3,high expres-sion of LINC00887,pathological grade Ⅲ-Ⅳ,and TNM stage Ⅲ-Ⅳ were risk factors for poor prognosis in ccRCC patients(P＜0.05).Spearman rank correlation analysis showed that there was a negative correlation between TNFAIP3 and LINC00887 expression in ccRCC tissue(r=-0.638,P=0.012).Conclusion TN-FAIP3 expression is down-regulated and L1NC00887 expression is up-regulated in ccRCC tissue,and there is a negative correlation.They may jointly regulate the occurrence and development of ccRCC,and have the poten-tial to become tumor markers for evaluating the prognosis of ccRCC patients.

ObjectiveTo study effect of brusatol （BR） on proliferation of human gastric cancer HGC-27 cells and its mechanism. MethodCell counting kit-8 （CCK-8） was used to detect the survival rate of HGC-27 cells at different concentrations of BR. HGC-27 cells were treated with BR （7.5， 15， 30 μmol·L^-1） for 24 h， and then the cell clone formation was analyzed. 2，7-Dichlorodihydrofluorescein diacetate （DCFH-DA） fluorescent probe and lipid peroxidation sensor （C11-BODIPY） were employed to detect the levels of intracellular reactive oxygen species （ROS） and lipid peroxidation， respectively. Real-time polymerase chain reaction （Real-time PCR） and Western blot were performed to detect the messenger ribonucleic acid （mRNA） and protein expressions of solute carrier family 7 member 11 （SLC7A11）， glutathione peroxidase 4 （GPX4）， solute carrier family 40 member 1 （SLC40A1）， transferrin， nuclear factor E₂-related factor 2 （Nrf2） and heme oxygenase-1 （HO-1）， respectively. ResultThe survival rate of HGC-27 cells was decreased with the increase of BR concentration， and the IC₅₀ was 15.34 μmol·L^-1. Compared with the conditions in blank group， the cell clone formation of BR （7.5， 15， 30 μmol·L^-1） groups was inhibited in a dose-dependent manner （P<0.05，P<0.01）， while the levels of intracellular ROS and lipid peroxidation， iron concentration， and lactic dehydrogenase （LDH） leakage were increased in a dose-dependent manner （P<0.05，P<0.01）. Compared with the blank group， the BR （15， 30 μmol·L^-1） groups lowered the mRNA and protein expressions of SLC7A11， GPX4， SLC40A1， Nrf2 and HO-1， while elevated the mRNA and protein expression of TRF in a dose-dependent manner （P<0.05，P<0.01）. ConclusionBR suppressed the proliferation of HGC-27 cells through inducing ferroptosis via inhibiting Nrf2/HO-1 pathway.

【Objective】 To explore the application of 1.2 mm×35 mm thin walled, long oblique angle syringe needle guided double-J tube insertion through abdominal wall in total laparoscopic ileal neobladder surgery. 【Methods】 Clinical data of 5 patients undergoing total laparoscopic ileal neobladder surgery in our hospital during Dec.2020 and Jan.2022 were retrospectively analyzed. Under laparoscopy and direct vision, 3 cm above pubic symphysis was taken as the puncture point, and an syringe needle was inserted to establish a channel. After that, a double-J tube was inserted under the guidance of the guide wire through the needle. 【Results】 The double-J tube was successfully implanted in all 5 patients. The time needed was 2-4 min, with an average of 3 min. 【Conclusion】 Under the guidance of a 1.2 mm×35 mm syringe needle, the placement of a double-J tube through the abdominal wall in total laparoscopic ileal neobladder surgery is safe, effective, simple and accurate. It can not only preserve the original operation channel without destroying the pneumoperitoneum, but also shorten the operation time. It is a new auxiliary means in total laparoscopic ileal neobladder surgery.

Objective:To investigate the application value of pelvic floor ultrasound in screening early postpartum stress urinary incontinence (SUI).Methods:A total of 220 postpartum women, who were admitted by the Department of Gynecology and Obstetrics of The People's Hospital of Hechi from January 2018 to June 2019, were selected for this study. These women were divided into SUI ( n = 52) and no SUI ( n = 168) groups according to whether SUI occurred within 42 days after delivery. Pelvic floor ultrasound parameters and clinical data were compared between the two groups. The effects of each ultrasound parameter on postpartum SUI were assessed. The receiver operating characteristic (ROC) curve was plotted for each parameter. The area under the ROC was calculated. The risk factors for postpartum SUI were investigated using the logistic regression analysis. Results:The number of deliveries (≥ 2 times), the proportion of women subjected to vaginal delivery, and neonatal weight in the SUI group were significantly higher than those in the no SUI group [ χ2 = 4.13, 3.30, t = 4.43, all P < 0.05]. There were significant differences in the bladder neck position and levator hiatus area in the resting state between the two groups ( t = 2.29, 3.09, both P < 0.05). There were significant differences in the bladder neck position, levator hiatus area, urethral rotation angle, and bladder neck mobility during the Valsalva movement between the two groups ( t = 13.14, 4.27, 15.64, 8.54, all P < 0.05). The areas under the ROC of bladder neck position and levator hiatus area in the resting state and the areas under the ROC of bladder neck position, levator hiatus area, urethral rotation angle, and bladder neck mobility during the Valsalva movement were 0.707, 0.725, 0.730, 0.771, 0.813, and 0.836, respectively. The area under the ROC of parameters used in combination was 0.849. Logistic regression analysis results revealed that the number of deliveries (≥ 2 times), bladder neck position (> 27.286 mm) and levator ani hiatus area in resting state (> 16.663 cm 2), and bladder neck position (< -2.774 mm), levator hiatus area (> 21.915 cm 2), urethral rotation angle (> 80.445°), and bladder neck mobility (> 30.501°) during the Valsalva movement were the risk factors for postpartum SUI. Conclusion:Combined use of pelvic floor ultrasound parameters is valuable for the diagnosis of postpartum SUI. Abnormal changes in the bladder neck position, levator ani hiatus area, urethral rotation angle, and bladder neck mobility are closely related to the occurrence of postpartum SUI. Therefore, combined use of pelvic floor ultrasound parameters can be preferred to screen early postpartum SUI.

Inflammatory bowel diseases (IBD) are a kind of non-specific inflammatory disease that occurs in gastrointestinal tract. Abnormal immune regulation is a key factor in its pathogenesis. The acquired immune regulation is mediated by helper T cells (Th), which is reported to play an important role in the pathogenesis of IBD. Th17 is a subtype of CD4 + T cells that could specifically produce interleukin-17 (IL-17) and other related cytokines. In this paper, we review the immune modulation of Th17 and its related cytokines in IBD.

Objective:The clinical characteristics and prognosis of 20 patients with small B-lymphocyte proliferative disease with t (14;19) (q32; q13) were analyzed to improve the understanding of such rare cases.Methods:The clinical data of 20 patients with t (14; 19) (q32; q13) small B lymphocyte proliferative disease treated in the First Affiliated Hospital of Nanjing Medical University from April 2013 to December 2020 were retrospectively collected and analyzed. Among them, 10 cases were chronic lymphocytic leukemia (CLL) and 10 cases were other small B-cell malignancies.Results:Among the 20 cases, 10 were male and 10 were female, and the median age at diagnosis was 53.5 (35-88) years old. All patients had absolute lymphocytosis, 19 patients had lymphadenopathy, and 10 patients had splenomegaly. With a median follow-up of 36 (4-163) months, three patients died, and 11 patients had a time to treatment (TTT) ≤12 months. Ten patients (50%) were accompanied by +12, two patients (2/17, 12%) were accompanied by 13q-. Moreover, we found that t (14;19) was associated with unmutated immunoglobulin heavy-chain variable (IGHV) somatic mutation (17/19, 89%) and a biased use of IGHV4-39 (7/17, 41%) was observed. Next-generation sequencing detected one or more gene mutations in 14 (14/17, 82%) cases and a total of 25 gene mutations had been revealed, of which the most frequent were NOTCH1 (35%) , followed by SF3B1 (24%) and KMT2D (18%) . For 10 CLL patients, five (50%) were defined as Rai Ⅲ/Binet C. It is noteworthy that among the 20 cases, two cases actually involved Richter transformation.Conclusions:Small B-cell malignant tumors with abnormal t (14; 19) show unique clinical biological characteristics, often accompanied by a variety of adverse prognostic factors, and tend to have an aggressive clinical course.
