OBJECTIVE: Salt-processed Psoraleae Fructus (SPF) is widely used as a phytoestrogen-like agent in the treatment of osteoporosis. However, due to improper clinical use or misuse, resulting in liver damage. In this study, network pharmacology was employed to analyze the mechanism of cholestatic liver damage. An adeno-associated virus overexpressing SULT1E1 (rAAV8-SULT1E1) was constructed and the hepatotoxicity of SPF, psoralen, and isopsoralen was determined. METHODS: By utilizing three databases inclding TCMSP, TCMID, and BATMAN- TCM, the targets of the three databases were summarized, and a total of 45 psoralen compounds were included. Network pharmacology analysis was then performed. The adenoviral vectors were injected into the tail vein of C57BL6 mice to elucidate the role of SULT1E1 in SPF-induced cholestasis-mediated hepatotoxicity in vivo. SPF (10 g/kg), psoralen, and isopsoralen (50 mg/kg each) were intragastrically administered to mice for 30 d. B-ultrasound and samples were collected and examined for follow-up experiments. RESULTS: A total of 854 targets were predicted for 45 active components, with 151 cholestasis-mediated hepatotoxicity-related disease targets obtained for SPF. A total of 126 pathways were enriched based on KEGG pathway analysis, with the "estrogen signaling pathway" identified as one of the top 20 pathways. In terms of pathological hepatic changes, treated mice had visually swollen hepatocytes, dilated bile ducts, and elevated serum biochemical markers, which were more prominent in mice treated with isopsoralen than in those treated with other compounds. Notably, the overexpression of SULT1E1 could reverse liver damage in each treatment group. B-ultrasound was used to observe the size of the gallbladder in vivo. The size of the gallbladder was found to significantly increase on day 30 after treatment in the SPF-, psoralen-, and isopsoralen-treated groups, especially the SPF group. Compared with the expression levels in the negative control group (rAAV8-empty + con), the expression levels of FXR, Mrp2, Bsep, SULT1E1, SULT2A1, Ntcp, and Nrf2 decreased, whereas those of CYP7a1 and IL-6 increased in the SPF-, psoralen-, and isopsoralen-treated groups. CONCLUSION The overexpression of SULT1E1 could alleviate the decreased or increased expression of indicators, indicating that SULT1E1 is an important target gene for SPF-induced liver damage. The severity of liver damage was significantly lower in the rAAV8-SULT1E1 groups than in the rAAV8-empty groups.

OBJECTIVE: To evaluate the decompensation effectiveness and alveolar bone remodeling of mandibular anterior teeth after preoperative orthodontic treatment in high-angle patients with skeletal class Ⅱ malocclusion using lateral cephalogram and cone-beam computed tomography (CBCT). METHODS: Thirty high-angle patients with skeletal class Ⅱ malocclusion who had received preoperative orthodontic treatment and orthognathic surgery in Peking University School and Hospital of Stomatology between Ja-nuary 2017 and August 2022 and had taken lateral cephalogram and CBCT before and after preoperative orthodontic treatment were selected. Items were measured with lateral cephalogram including: The lower central incisor (L1)-Frankfort plane angle (L1-FH), the L1-mandibular plane angle (L1-MP), the L1-nasion-supramental angle (L1-NB) and the vertical distance from the incisal edge of lower central incisor to NB line (L1-NB distance), etc. The incidence of dehiscence/fenestration and the length of dehiscence at labial side (d-La) and lingual side (d-Li) were measured using CBCT. Pearson correlation analysis was used to evaluate the correlation between the changes of d-Li of L1 and age, duration of preoperative orthodontic treatment and the cephalometric measurements before preoperative orthodontic treatment to screen out risk factors affecting the periodontal risk of preoperative orthodontic treatment in high-angle patients with skeletal class Ⅱ malocclusions. RESULTS: After preoperative orthodontic treatment, L1-FH, L1-MP, L1-NB and L1-NB distances changed by 11.56°±5.62°, -11.13°±5.53°, -11.57°±5.43° and (-4.99±1.89) mm, respectively, and the differences were all statistically significant (P < 0.05). Among the 180 measured mandibular anterior teeth, 45 cases with labial dehiscence/fenestration before preoperative orthodontic treatment (T0) had no longer labial dehiscence/fenestration after preope-rative orthodontic treatment (T1); 142 cases without lingual dehiscence/fenestration at T0 had lingual dehiscence/fenestration at T1. After preoperative orthodontic treatment, the d-La of lower lateral incisors (L2), lower canines (L3) and lower anterior teeth (L1+L2+L3) decreased by (0.95±2.22) mm, (1.20±3.23) mm and (0.68±2.50) mm, respectively, and the differences were statistically significant (P < 0.05); the d-Li of L1, L2, L3 and L1+L2+L3 increased by (4.43±1.94) mm, (4.53±2.35) mm, (3.19±2.80) mm and (4.05±2.46) mm, respectively, and the differences were statistically significant (P < 0.05). The increase of d-Li of L1 was positively correlated with L1-FH (r=0.373, P=0.042). CONCLUSION This study showed that high-angle patients with skeletal class Ⅱ ma-locclusion could achieve ideal decompensation effect of mandibular anterior teeth after preoperative orthodontic treatment with bilateral mandibular first premolars extracted, but the lingual periodontal risk of mandibular anterior teeth was increased. This risk could be correlated to L1-FH before preoperative orthodontic treatment, which should be paid more attention in the design of orthodontic-orthognathic surgical treatment.

OBJECTIVE: To investigate the clinical efficacy of percutaneous screw fixation combined with minimally invasive transpedicular bone grafting and non-bone grafting in the treatment of thoracolumbar fractures. METHODS: From Janury 2021 to June 2022, 40 patients with thoracolumbar fracture were divided into the experimental group and the control group. There were 26 patients in the experimental group, including 21 males and 5 females with an aberage age of (47.3±12.3) years old, who underwent percutaneous pedicle screw fixation combined with transpedicular autogenous bone grafting. In the control group, 14 patients received percutaneous pedicle screw fixation only. including 7 makes and 7 females with an average age of (50.2±11.2) years old. The operative time, intraoperative blood loss, anterior height ratio of injured vertebrae, Cobb angle, visual analogue score (VAS), MacNab scores, loosening or broken of the implants. were compared and analyzed. RESULTS: There was no significant difference in operation time, intraoperative blood loss, VAS and anterior height ratio of injured vertebrae between the two groups. Compared with the preoperative results, VAS and anterior height ratio of injured vertebrae were improved statistically(P<0.05). For Cobb angle of injured vertebra, there was no significant difference between the two groups before surgery (P=0.766). While at 1 week, 3 months and 12 months after surgery, there were statistically differences between the two groups (P values were 0.042, 0.007 and 0.039, respectively). The Cobb angle of injured vertebrae one year after operation was statistically decreased in both groups compared with that before surgery (P<0.001). One year after surgery, the excellent and good rate of Macnab scores was 96.15% in the experimental group and 92.86% in the control group, and there was no statistical differences between the two groups (P=0.648). There was one patient in the control group suffering superficial wound infection on the third day, which was cured by dressing change and anti-infection treatment. There were no postoperative screw loosening and broken in both groups. CONCLUSION The two surgical methods have the advantages of less trauma, less pain and quicker recovery, which can restore the height of the injured vertebra, reconstruct the spinal sequence and reduce the fracture of the vertebral body. Transpedicular autogenous bone grafting can increase the stability of the fractured vertebra and maintain the height of the vertebra better after surgery, thus reducing the possibility of complications such as kyphosis, screw loosening and broken.

Objective:To investigate the risk factors affecting the completion of postoperative adjuvant chemotherapy in elderly patients with progressive gastric cancer.Methods:Clinicopathological data of patients diagnosed with gastric adenocarcinoma and treated with radical surgery at our hospital between January 2017 and December 2018 were retrospectively collected, and 96 patients were finally included in the study according to the inclusion and exclusion criteria.Patients were divided into a completed chemotherapy group and an uncompleted chemotherapy group depending on whether they had completed 6 cycles of adjuvant chemotherapy after surgery.The optimal cut-off value was derived from the receiver operating characteristic(ROC)curve, and the Youden Index was calculated.Relevant factors that might affect the completion of postoperative adjuvant chemotherapy in elderly patients with progressive gastric cancer were included in univariate and multivariate Logistic regression analyses to identify independent risk factors affecting the completion of postoperative adjuvant chemotherapy in gastric cancer patients.The Kaplan-Meier(K-M)method was used to plot the survival curves for the groups, and the log-rank test was used to compare the survival rates between the groups.Results:A total of 96 patients, aged 60-89 years, with a mean age of(70.3±7.0)years, were included.Sixteen patients completed postoperative adjuvant chemotherapy, while 80 patients did not.The following analysis was performed on clinicopathological data of patients in the two groups.Univariate Logistic regression analysis showed that patient age ≥70 years( OR=8.135, 95% CI: 1.735-38.153, P=0.008)or a preoperative prognostic nutritional index(PNI)score <49.5( OR=4.765, 95% CI: 1.549-14.656, P=0.006)affected the completion of postoperative adjuvant chemotherapy.The risk factors that might affect the completion of postoperative adjuvant chemotherapy in elderly gastric cancer patients were analyzed using multivariate Logistic regression and the results showed that age ≥70 years( OR=9.815, 95% CI: 1.947-49.485, P=0.006)and a preoperative PNI score <49.5( OR=5.895, 95% CI: 1.711-20.305, P=0.005)were independent risk factors hindering the completion of postoperative adjuvant chemotherapy. Conclusions:Age ≥70 years and PNI<49.5 are independent risk factors for the completion of postoperative adjuvant chemotherapy.Failure to complete postoperative adjuvant chemotherapy is associated with a poor prognosis.PNI is a valid predictor for whether postoperative adjuvant chemotherapy will be completed and helps to screen chemotherapy patients who need nutritional intervention.

Schistosomiasis was once endemic in 12 provinces (municipalities, autonomous regions) along and south of the Yangtze River basin, which seriously damages human health and hinders socioeconomic developments in China. Following the concerted efforts for 70 years, remarkable achievements have been gained in the national schistosomiasis control program of China. However, there are still multiple challenges for elimination of schistosomiasis in the country. This paper describes the current status of schistosomiasis and the challenges during the progress towards the elimination of schistosomiasis, and proposes the goals, key points and research priorities of schistosomiasis control in China during the 14th Five-Year Plan Period.

BACKGROUND: There were few studies on real-world data about autologous hematopoietic stem cell transplantation (auto-HSCT) or allogeneic HSCT (allo-HSCT) in peripheral T-cell lymphoma (PTCL). This study aimed to investigate the clinical outcomes of patients who received auto-HSCT or allo-HSCT in China. METHODS: From July 2007 to June 2017, a total of 128 patients who received auto-HSCT (n  = 72) or allo-HSCT (n  = 56) at eight medical centers across China were included in this study. We retrospectively collected their demographic and clinical data and compared the clinical outcomes between groups. RESULTS: Patients receiving allo-HSCT were more likely to be diagnosed with stage III or IV disease (95% vs. 82%, P = 0.027), bone marrow involvement (42% vs. 15%, P = 0.001), chemotherapy-resistant disease (41% vs. 8%, P = 0.001), and progression disease (32% vs. 4%, P < 0.001) at transplantation than those receiving auto-HSCT. With a median follow-up of 30 (2-143) months, 3-year overall survival (OS) and progression-free survival (PFS) in the auto-HSCT group were 70%(48/63) and 59%(42/63), respectively. Three-year OS and PFS for allo-HSCT recipients were 46%(27/54) and 44%(29/54), respectively. There was no difference in relapse rate (34%[17/63] in auto-HSCT vs. 29%[15/54] in allo-HSCT, P = 0.840). Three-year non-relapse mortality rate in auto-HSCT recipients was 6%(4/63) compared with 27%(14/54) for allo-HSCT recipients (P = 0.004). Subanalyses showed that patients with lower prognostic index scores for PTCL (PIT) who received auto-HSCT in an upfront setting had a better outcome than patients with higher PIT scores (3-year OS: 85% vs. 40%, P = 0.003). Patients with complete remission (CR) undergoing auto-HSCT had better survival (3-year OS: 88% vs. 48% in allo-HSCT, P = 0.008). For patients beyond CR, the outcome of patients who received allo-HSCT was similar to that in the atuo-HSCT group (3-year OS: 51% vs. 46%, P = 0.300). CONCLUSIONS Our study provided real-world data about auto-HSCT and allo-HSCT in China. Auto-HSCT seemed to be associated with better survival for patients in good condition (lower PIT score and/or better disease control). For patients possessing unfavorable characteristics, the survival of patients receiving allo-HSCT group was similar to that in the auto-HSCT group.

The culture of schistosomiasis control is specific in the history of Chinese culture. Broadly speaking, the culture of schistosomiasis control is a summary of specific social mood, social consciousness and material culture created by Chinese populations during the progress of schistosomiasis control since the founding of the People’s Republic of China. Narrowly speaking, the culture of schistosomiasis control is the spiritual culture that is jointly created and nurtured by schistosomiasis control workers since the founding of the People’s Republic of China. The spiritual features of Chinese schistosomiasis control culture are characterized by the patriotism and care about the people, the matter-to-fact attitude, the pioneering and enterprising spirit, and the spirit of sacrifice and dedication. The ultimate goal of the research on the culture of schistosomiasis control is to facilitate the achievement of the strategic goal of Healthy China 2030 as scheduled, accelerate the progress towards elimination of schistosomiasis, and to promote the sustainable development of schistosomiasis control in China.

This paper describes the current epidemic characteristics and endemic status of schistosomiasis, analyzes the main challenges of schistosomiasis control and proposes the emphasis and interventions for future schistosomiasis control activities in Hunan Province, so as to provide insights into the elimination of schistosomiasis in Hunan Province.

Objective:To evaluate the clinical efficacy of Sanjiao Cidi therapy on acute cerebral infarction and its effect on levels of S100-β protein （S100-β）， tumor necrosis factor-α （TNF-α）， hypersensitive C-reactive protein （hs-CRP） and neuropeptide （NPY）. Method:One hundred and eighty patients were randomly divided into control group （90 cases） and observation group （90 cases） by random number table. Patients in control group got aspirin enteric-coated tablets， 100 mg/time， 1 time/day， edaravone injection （injected within 30 minutes） for 14 days， 30 mg/time， 2 times/day， simvastatin tablets， 20 mg/time， 1 time/day. In addition to the basic therapy of meloxicam tablets， patients in observation group were also treated with Sanjiao Cidi therapy. In the first step， patients got Guizhi therapy to dredge Zhongjiao and Shangjiao， 1 dose/day， for 8 days. In the second step， patients got Sini therapy to dredge Zhongjiao and Xiajiao， 1 dose/day， for 10 days. In the third step， patients got Tianjing Gubentherapy， 1 dose/day， for 10 days. The course of treatment was 4 weeks. Before the treatment， and at the first， second， third and fourth weeks after treatment， National Institutes of Health Stroke Scale （NIHSS） was scored. And before and after treatment， function scale of fuglmeyer （FMA）， ability of daily life activities （ADL）， mini-mental state examination （MMSE） and main symptoms of traditional Chinese medicine were scored. Comprehensive assessment of patient report outcome （PRO） was made. And levels of S100-β， hs-CRP， TNF-α and NPY were detected. And the incidence rate of pulmonary infection， urinary infection， skeletal myalgia， shoulder hand syndrome and shoulder subluxation of patients were recorded during hospitalization. Result:The clinical efficacy in observation group was better than that in control group （Z=2.141， P<0.05）. Scores of NIHSS in observation group were lower than those in control group at the first， second， third and fourth weeks after treatment （P<0.01）. Scores of upper limb， legs and the total scores from FMA were higher than those in control group （P<0.01）. Scores of the main symptoms of traditional Chinese medicine， symptoms， psychological and social scores， total scores of PRO， S100-β， hs-CRP， TNF-α and NPY were lower than those in the observation group （P<0.01）. And scores of ADL and MMSE were higher than those in control group （P<0.01）. Total incidence of complications in observation group was 27.27%（21/77）， which was lower than 46.15%（36/78） in control group （χ²=5.941， P<0.05）. Conclusion:In addition to conventional western medicine treatment， Sanjiao Cidi therapy can treat the patients with acute cerebral infarction， alleviate the degree of neurological deficit， improve the cognitive function， motor function of limbs and the ability of daily life， reduce the main symptoms of traditional Chinese medicine， the incidence of complications and the inflammatory response， protect the nerve cells， with a better clinical efficacy and comprehensive effect in patients than pure Western medicine.
