Objective To evaluate the value of serum Mac-2 binding protein (M2BP) for assessment of the severity of schisto somiasis-induced liver fibrosis, so as to provide insights into non-invasive diagnosis and disease surveillance of liver fibrosis caused by schistosomiasis. Methods A total of 234 individuals with a history of Schistosoma japonicum infection were sampled from Xinhua Village, Lushan City, Jiangxi Province from 2019 to 2020, and 234 serum samples were collected from all participants. All participants received B-ultrasound examinations of the liver. Serum samples were categorized into four groups (grades 0, Ⅰ, Ⅱ and Ⅲ schistosomiasis-induced liver fibrosis groups) according to B-ultrasound examination results, and then, each group was randomly divided into a receiver operating characteristic (ROC) curve group and an efficacy assessment group at a ratio of 7∶3. Serum M2BP concentration was measured in four groups using the enzyme-linked immunosorbent assay (ELISA), and differences in serum M2BP concentrations were compared with analysis of variance and Spearman correlation analysis. Serum M2BP concentration was subjected to ROC curve analysis among individuals with different grades of schistosomiasis-induced liver fibrosis in the ROC curve group to determine the optimal diagnostic threshold of M2BP concentration at different fibrosis grades, and the area under the ROC curve (AUC) was calculated to evaluate the diagnostic performance. The diagnostic accuracy was verified by comparing the accordance rate and Kappa consistency test in the efficacy assessment group. Results Among 234 serum samples, there were 79 samples with grade 0 schistosomiasis-induced liver fibrosis, 87 samples with Grade Ⅰ, 46 samples with Grade Ⅱ and 22 samples with Grade Ⅲ according to the B-ultrasound examinations. The mean serum M2BP concentrations were (0.40 ± 0.31) [95% confidence interval (CI): (0.33, 0.47)], (0.64 ± 0.48) [95% CI: (0.53, 0.74)], (1.76 ± 0.58) [95% CI: (1.59, 1.93)] μg/mL and (2.56 ± 0.93) [95% CI: (2.14, 2.97)] μg/mL in the four groups, respectively (F = 150.796, P < 0.001), and the severity of schistosomiasis-induced liver fibrosis significantly positively correlated with serum M2BP concentration (rs = 0.715, P < 0. 001). The sample sizes of grades 0, Ⅰ, Ⅱ and Ⅲ schistosomiasis-induced liver fibrosis sera were randomly allocated as follows: 55 versus 24, 61 versus 26, 32 versus 14, and 15 versus 7 in the ROC curve and efficacy assessment groups, respectively, and the serum M2BP concentrations were (0.39 ± 0.29) μg/mL and (0.42 ± 0.36) μg/mL (F = 0.196, P > 0.05), (0.59 ± 0.47) μg/mL and (0.75 ± 0.51) μg/mL (F = 1.967, P > 0.05), (1.73 ± 0.59) μg/mL and (1.85 ± 0.57) μg/mL (F = 0.417, P > 0.05), and (2.46 ± 0.64) μg/mL and (2.76 ± 1.41) μg/mL (F = 0.491, P > 0.05), respectively. ROC curve analysis showed that the optimal diagnostic thresholds of serum M2BP concentration were 0.347 86 μg/mL (AUC = 0.635, P < 0.05), 1.188 83 μg/mL (AUC = 0.938, P < 0.000 1) and 2.021 21 μg/mL (AUC = 0.821, P < 0.000 1) for grade Ⅰ, Ⅱ and Ⅲ schistosomiasis-induced liver fibrosis. In addition, the accordance rates between the optimal diagnostic threshold of serum M2BP and B-ultrasound examinations for predicting grade Ⅰ, Ⅱ and Ⅲ schistosomiasis-induceed liver fibrosis were 69.23%, 85.71% and 71.43% (χ2 = 1.340, P > 0.05), and the overall Kappa consistency test showed moderate consistency [Kappa = 0.608, 95% CI: (0.428, 0.788); Z = 6.609, P < 0.000 1]. Conclusions Serum M2BP may serve as a potential biomarker for assessing moderate to advanced schistosomiasis-induced liver fibrosis; however, its diagnostic value for early-stage schistosomiasis-induced liver fibrosis remains limited.

Objective To observe the clinical effect of trimodal pre-rehabilitation strategy in patients undergoing pancreatoduodenectomy. Methods A total of 110 patients undergoing elective pancreaticoduodenectomy were selected as the study objects. Patients were randomly divided into control group and observation group according to the odd-even order, with 55 cases in each group. The control group was given routine nursing during perioperative period, and the observation group was given trimodal pre-rehabilitation nursing before surgery based on the control group. The psychological state, quality of life, postoperative indexes and complications of the two groups were observed and compared. Serum albumin (ALB), prealbumin (PA) and transferrin (TRF) levels were detected in two groups. Results Postoperative exhaust time, getting out of bed time, first oral feeding time and hospital stay in the observation group were significantly shorter than those in the control group (P < 0.05). At 1 day before surgery and 14 days after surgery, the levels of ALB, PA, TRF and 36-item Short Form Health Assessment Scale (SF-36) in the observation group were significantly higher than those in the control group, and the Hospital Anxiety and Depression Scale (HADS) scores were significantly lower than those in the control group (P < 0.01 or P < 0.05). The incidence of pulmonary infection and venous thrombosis in the observation group was significantly lower than that in the control group (P < 0.05). Conclusion Trimodal pre-rehabilitation nursing intervention can effectively improve the perioperative nutritional status and psychological state of patients with pancreaticoduodenectomy, improve their quality of life and reduce the incidence of complications.

Objective:To explore the effect of bidirectional barb absorbable thread in " double ring method" cosmetic surgery for breast ptosis patients.Methods:From June 2016 to September 2019, 85 patients with breast ptosis aged 24-48 (36.28±6.53) years who completed the " double loop method" cosmetic plastic surgery with traditional absorbable sutures were admitted to the Medical Plastic Surgery and Cosmetology Department of Henan University of Science and Technology First Affiliated Hospital New Area as group A. From October 2019 to February 2022, 90 patients with breast ptosis aged 24-50 (35.72±6.43) years who completed the " double loop method" cosmetic plastic surgery with bidirectional barb absorbable thread were selected as group B. The incision suture time and incision healing time were compared between the two groups, and the postoperative incision healing grade, incision scar degree and patient aesthetic satisfaction were compared between the two groups.Results:The incision suture time and incision healing time in group B were (13.78±2.49) min and (7.69±1.27) d, respectively, which were shorter than those in group A (18.23±3.94) min and (10.36±1.78) d ( t=8.98, 11.47, both P<0.05). There was no significant difference in incision healing grade between mild breast ptosis and moderate breast ptosis between the two groups ( P>0.05). There was no significant difference in incision healing grade between the two groups ( P>0.05). There was no significant difference in the degree of incision scar between mild breast ptosis and moderate breast ptosis between the two groups ( P>0.05). The formation rate of superficial scar in group B was 84.44% (76/90), which was higher than 62.35% (53/85) in group A (χ 2=11.01, P<0.05). The formation rates of hyperplastic scar and atrophic scar in group A were 12.22% (11/90) and 3.33% (3/90) respectively, which were lower than 27.06% (23/85) and 10.59% (9/85) in group A (χ 2=4.56, 4.26, both P<0.05). The total aesthetic satisfaction of group B was 93.33% (84/90), which was higher than 81.18% (69/85) in group A (χ 2=5.88, P<0.05). Conclusions:Bidirectional barb absorbable thread can reduce the time of incision suture and incision healing, improve patients′ incision aesthetics and increase the satisfactory rate.

Objective:To evaluate the reliability and validity of the Chinese version of HEMO-FISS-QoL(HF-QoL) questionnaire (HF-QoL-C) in the Chinese population with hemorrhoids.Methods:From November 2021 to November 2022, a self-constructed general information questionnaire, HF-QoL-C, and the 36-item short form health survey (SF-36), Goligher classification, and Giordano severity of hemorrhoid symptom questionnaire (GSQ) were used to conduct a questionnaire survey on 760 hemorrhoid patients in the anorectal department of six hospitals. The data was analyzed for reliability and validity using SPSS 21.0 and AMOS 26.0 software.Results:The Cronbach's α coefficient of HF-QoL-C and its dimension ranged from 0.831 to 0.960, and the split coefficient was 0.832-0.915. Four common factors were extracted through principal component exploratory factor analysis. Confirmatory factor analysis indicated acceptable structural validity( χ2/ df=8.152, RSMEA=0.097, CFI=0.881, IFI=0.881, NFI=0.867). HF-QoL-C was correlated with SF36 and GSQ( r=-0.694, 0.501, both P<0.01). There were differences in the total score and dimensional scores of HF-QoL-C between surgical and drug treated patients, different grades of Goligher classification for hemorrhoidal disease, and different ranges of hemorrhoid prolapse (all P<0.001). No ceiling effect was found in the total score and the scores of each dimension(0.3%-2.0%). There was a floor effect in both psychological function and sexual activity dimensions (16.7%, 35.1%). Conclusion:HF-QoL-C has good reliability and validity, which can be used to measure the quality of life of Chinese hemorrhoid patients.

Objective To confirm the changes of pulmonary artery pressure, neo pulmonary artery stenosis and reoperation in children with unilateral absence of pulmonary artery (UAPA) undergoing pulmonary artery reconstruction. Methods The clinical data of the infants with UAPA undergoing pulmonary artery reconstruction in our hospital from February 19, 2019 to April 15, 2021 were analyzed. Changes in pulmonary artery pressure, neo pulmonary artery stenosis and reoperation were followed up. Results Finally 5 patients were collected, including 4 males and 1 female. The operation age ranged from 13 days to 2.7 years. Cardiac contrast-enhanced CT scans were performed in all children, and 2 patients underwent pulmonary vein wedge angiography to confirm the diagnosis and preoperative evaluation. Preoperative transthoracic echocardiography and intraoperative direct pulmonary arterial pressure measurement indicated that all 5 children had pulmonary hypertension, with a mean pulmonary arterial pressure of 31.3±16.0 mm Hg. Pulmonary arterial pressure decreased immediately after pulmonary artery reconstruction to 16.8±4.2 mm Hg. The mean follow-up time was 18.9±4.7 months. All 5 patients survived during the follow-up period, and 1 patient had neo pulmonary artery stenosis or even occlusion and was re-operated. Conclusion Pulmonary artery reconstruction can effectively alleviate the pulmonary hypertension in children with UAPA. The patency of the neo pulmonary artery should be closely followed up after surgery, and re-pulmonary angioplasty should be performed if necessary.

ObjectiveTo investigate the mechanism by which Liuwei Dihuang Erzhiwan combination inhibit the lung metastasis of spontaneous breast cancer in mice by regulating the recruitment of myeloid-derived suppressor cells （MDSCs）. MethodThree hundred and eighty SPF-grade 10-month-old female breeders of Kunming mouse were palpated at the mammary gland site once every 3 days. Mice that have not had a lump touched after being raised for 6 months are used as control group. After tumor development， the mice were randomized into model， positive control （paclitaxel， intraperitoneal injection at 0.01 g·kg^-1 every other day for 22 d）， Liuwei Dihuangwan （0.65 g·kg^-1·d^-1 by gavage）， Erzhiwan （5.41 g·kg^-1·d^-1 by gavage）， and Liuwei Dihuang Erzhiwan combination （6.05 g·kg^-1·d^-1 by gavage） groups. The mice were euthanised when the tumor reached a diameter of about 15 mm， and the tumor and lung tissues were collected. The survival time， tumor mass， and lung metastasis rate of tumor-bearing mice were recorded. Hematoxylin-eosin （HE） staining was used to observe the histopathological and morphological changes of mouse tumor and lung tissues. Immunofluorescence （IF） was used to detect the distribution of MDSCs in tissues of mice in each group by double-staining of MDSCs cells with lymphocyte antigen 6 complex site G6D （Ly6G） and CD11 antigen-like family member B （CD11b）. Western blot was employed to determine the protein levels of matrix metalloproteinase-9 （MMP-9）， transforming growth factor-β （TGF-β）， zinc finger transcription factor 1 （Snail1）， and E-cadherin in the tumor tissue and CC motif chemokine 9 （CCL9） and CC motif chemokine receptor 1 （CCR1） in the lung tissue. ResultDuring the modelling period， the paclitaxel group and Chinese medicine intervention groups had longer median number of days of survival and lower tumor weight， lung metastasis rate， and lung nodule than the model group （P<0.05， P<0.01）. HE staining showed an increase in tumor cell necrosis in the paclitaxel group and the Liuwei Dihuang Erzhiwan combination group. The paclitaxel group and Chinese medicine intervention groups had lower fluorescence intensity of MDSCs in the tumor tissue than the model group （P<0.05， P<0.01）. Compared with the normal control group， the model group showed increased fluorescence intensity of MDSCs in the metastatic lung tissue （P<0.01）， which， however， was decreased in the paclitaxel group and Chinese medicine intervention groups （P<0.01）. The model group showed higher protein levels of MMP-9， TGF-β， and Snail1 and lower protein level of E-cadherin in the tumor tissue than in the normal control group （P<0.01）. Compared with model group， paclitaxel and Chinese medicine interventions downregulated the protein levels of MMP-9， TGF-β， and Snail1 （P<0.05， P<0.01） and upregulated the protein level of E-cadherin in the tumor tissue （P<0.01）. Moreover， the Liuwei Dihuang Erzhiwan combination group had lower protein levels of TGF-β and Snail1 than the Liuwei Dihuangwan group and Erzhiwan group （P<0.05）. In the metastatic lung tissue， the expression of CCL9 and CCR1 was higher in the model group than in the normal control group， paclitaxel group， and Chinese medicine intervention groups （P<0.05， P<0.01）. ConclusionLiuwei Dihuang Erzhiwan combination inhibit tumor growth， prolong survival time， and reduce the occurrence of lung metastasis in the mouse model of spontaneous breast cancer by reducing the recruitment of MDSCs in the tumor and lung tissues and modulating the phenotypes of epithelial-mesenchymal transition （EMT）-related molecules and the expression of CCL9/CCR1.
