ObjectiveTo systematically and objectively characterize the pharmacological effects of Fufang Biejia Ruangan pills （FBRP） in the intervention of alcoholic liver disease （ALD） using acute and chronic ALD mouse models and to elucidate its molecular mechanisms. MethodFifty SPF-grade male BALB/c mice were randomly divided into the normal group， model group， and FBRP low-， medium-， and high-dose groups （9.6， 19.2， 38.4 mg·kg^-1）. Except for the normal group， the remaining groups were given 56° white wine by gavage to establish the acute ALD model， with samples collected after 4 weeks. Thirty SPF-grade male C57BL/6N mice were randomly divided into the normal group， model group， and FBRP medium-dose group （19.2 mg·kg^-1）. The chronic ALD mouse model was established using the Lieber-DeCarli method over a 10-week period. Inflammatory markers in liver tissues were assessed using hematoxylin-eosin （HE）， Sirius Red， oil red O staining， and enzyme-linked immunosorbent assay （ELISA）. Intoxication behaviors of each group were objectively evaluated through sobering-up time， net-catching， and pole-climbing tests. Further bioinformatics analyses based on clinical transcriptomic data were conducted to identify key targets and molecular mechanisms of FBRP in alleviating ALD through liver-brain dialogue， with experimental validation by ELISA， Western blot， and immunohistochemical staining. ResultCompared with the normal group, the levels of aspartate aminotransferase （AST） and alanine aminotransferase （ALT） in liver tissues of mice in the acute and chronic ALD model groups were significantly increased （P<0.05）. Compared with the model group， the levels of AST and ALT in liver tissue of mice in FBRP groups were significantly decreased （P<0.05）. Compared with the normal group， the time of grasping the net and climbing the pole in the acute ALD model group was significantly decreased within 4 weeks （P<0.01）. Compared with the model group， the grasping and climbing time of FBRP high dose groups increased significantly within 4 weeks （P<0.05）. Compared with the normal group， the expression of high mobility group protein B1 （HMGB1） protein in liver tissue and prefrontal lobe tissue of mice in the chronic ALD model group was significantly increased （P<0.01）. Compared with the model group， the expression of HMGB1 protein in FBRP medium dose group was significantly decreased （P<0.05，P<0.01）. Compared with the normal group， the expression of brain-derived neurotrophic factor （BDNF） protein and the release of γ-aminobutyric acid （GABA） in the prefrontal cortex of the model group were significantly decreased （P<0.01）. Compared with the model group, the expression of BDNF protein and the release of GABA in the FBRP medium dose group were significantly increased （P<0.05）. ConclusionThis study revealed that FBRP improved key pathological changes in ALD by modulating liver-brain dialogue mediated by the HMGB1-BDNF axis. These findings provide experimental evidence for the clinical use of FBRP in treating ALD and offer new insights for the development of ALD therapeutic agents.

Endo-periodontal lesions(EPLs)involve both the periodontium and pulp tissue and have complicated etiologies and pathogenic mechanisms,including unique anatomical and microbiological characteristics and multiple contributing factors.This etiological complexity leads to difficulties in determining patient prognosis,posing great challenges in clinical practice.Furthermore,EPL-affected teeth require multidisciplinary therapy,including periodontal therapy,endodontic therapy and others,but there is still much debate about the appropriate timing of periodontal therapy and root canal therapy.By compiling the most recent findings on the etiology,pathogenesis,clinical characteristics,diagnosis,therapy,and prognosis of EPL-affected teeth,this consensus sought to support clinicians in making the best possible treatment decisions based on both biological and clinical evidence.

Objective:To investigate the dosimetric effects of prone immobilization devices combined with a belly board (PIDBBs) in the intensity-modulated radiotherapy (IMRT) for gynecologic cancers.Methods:A total of 20 patients with cervical or endometrial cancer treated with radiotherapy in the Third Affiliated Hospital of Sun Yat-sen University from August 2020 to June 2021 were retrospectively analyzed. Two sets of body contours were outlined for each patient. One set of body contours did not contain the immobilization devices, and the other contour set included the immobilization devices. For each patient, doses were calculated for the two sets of contours using the same 7-field IMRT plan and were recorded as Plan without and Plan with. The dosimetric difference caused by the immobilization devices was assessed by comparing the parameter values in the dose-volume histograms (DVHs) and by plan subtraction. The Gafchromic EBT3 film and anthropomorphic phantom were used to verify the calculated doses. Results:The target coverage and average dose of Plan with were lower than those of Plan without. Specifically, the V50 Gy, V49 Gy, and Dmean of planning target volume (PTV) decreased by 19.75%, 7.99%, and 2.54% ( t = 8.96, 10.49, 22.09, P < 0.01), respectively. The V40 Gy, V30 Gy, V20 Gy, V15 Gy, and Dmean of skins increased by 51.79%, 51.05%, 45.72%, 33.63% and 10.80% ( t = -2.54, -5.63, -15.57, -24.06, -13.88, P < 0.01), respectively. Doses to other organs at risk (OARs) showed no significant differences. As indicated by the EBT3 measurements, the doses to skins of the abdomen and pelvis on the anthropomorphic phantom increased by approximately 37.24% ( t = 10.86, P<0.01). Conclusions:Although PIDBBs can effectively reduce the low dose to the small intestine, the radiation attenuation caused by them can reduce the PTV coverage of radiotherapy plans and increase the doses to abdominal and pelvic skins sharply, especially for patients requiring irradiation of the groin and perineum.

Objective To explore imaging predictors in elderly patients with first-ever ischemic stroke combined with asymptomatic coronary artery disease(ACAD).Methods A total of 241 non-cardioembolic ischemic stroke patients within 14 d of symptom onset admitted to the neuro-logical department of our hospital from September 2019 to November 2021 were consecutively en-rolled.Based on the diagnosis,they were divided into an ACAD group(103 cases)and a non-ACAD group(138 cases).All patients underwent routine brain MRI and hybrid coronary and cer-vicocephalic CT angiography.Logistic regression analysis was used to identify factors influencing the presence of ACAD in these patients.Results The ACAD group had significantly larger ratios of males,smoking,silent brain infarcts(SBI,both single and multiple),positive stenosis in in-tracranial arteries,numbers of positive stenotic segments in intracranial and extracranial arteries,and total number of positive stenotic segments in head and neck arteries when compared with the non-ACAD group(P＜0.05,P＜0.01).Multivariate logistic regression analysis revealed that both single and multiple SBI were independent risk factors for ACAD(OR=4.474,95％CI:2.057-9.731,P=0.001;OR=8.071,95％CI:3.945-16.513,P=0.001).Conclusion SBI is an independ-ent predictive factor for ACAD in elderly patients with first-ever ischemic stroke,and it has better predictive value than cerebral white matter hyperintensities and intracranial/extracranial arterial stenosis for ACAD.

Objective:To explore the expectations and values of patients with malocclusion on participation in shared decision-making of orthognathic surgical protocols, and to provide references for further development of clinical shared decision-making models.Methods:Based on the expected value theory and descriptive qualitative research methods, using purposive sampling, 13 patients with malocclusion in the Ninth People's Hospital of Shanghai Jiao tong University School of Medicine from May to August in 2021 were selected for semi-structured interviews. The interview data were sorted, classified and refined by traditional content analysis.Results:Two themes were extracted: patients' ability beliefs about their ability to participate in shared decision making for orthognathic surgery(decision support ability, psychological coping ability and environmental adaptability), and task values for shared decision making for orthognathic surgery(interest value, acquisition value).Conclusions:Low level of patients′ ability beliefs in shared decision-making, active physician guidance facilitates patient participation, but the depth of patient participation is influenced by factors such as information support, cultural climate, and physical space for shared decision making. It is suggested that the magnetic role of physicians should be actively played, the shared decision-making team should be strengthened, at the same time, hospital manager should enhance shared decision making propaganda to increase the acceptance and participation of patients in shared decision making so as to improve the quality of shared decision-making.

Objective:To explore the application value of apparent diffusion coefficient (ADC) of magnetic resonance diffusion weighted imaging (DWI) parameters in glioma classification and glioma microstructure evaluation.Methods:From June 2017 to November 2019, 38 patients with glioma confirmed by surgery and pathology in Haikou Hospital Affiliated to Xiangya Medical College of Central South University were retrospectively analyzed. According to the pathological results, they were divided into low-grade (WHO Ⅰ-Ⅱ, 15 cases) glioma group and high-grade (WHO Ⅲ-Ⅳ, 23 cases) glioma group. They received magnetic resonance imaging (MRI) plain scan and DWI scan respectively, and the ADC value and microstructure of different grades of glioma were compared. The correlation between ADC value of glioma and the percentage of vascular endothelial growth factor (VEGF)-positive cells, cell density and integrated optical density (IOD) value of aquaporin 1 (AQP1) expression was analyzed.Results:(1) MRI examination showed that the signals of low-grade glioma were more uniform, with no or slight peritumoral edema and space occupying effect, and the enhancement was more non enhanced or slightly enhanced. The signals of high-grade glioma were more heterogeneous due to necrosis and bleeding, and the peritumoral edema and space occupying effect were more obvious, showing uneven obvious enhancement or irregular ring enhancement; (2) The percentage of VEGF positive cells, cell density and the IOD value of AQP1 expression in high-grade glioma were significantly higher than that in low-grade glioma, and the ADC value was lower than that in low-grade glioma (all P<0.05); (3) The ADC value of glioma patients was negatively correlated with the percentage of VEGF-positive cells, cell density, and the IOD value of AQP1 expression ( r=-0.55, -0.65, -0.63, all P<0.05). Conclusions:The ADC value of glioma can indirectly reflect the expression of VEGF, cell density and AQP1 positive expression level, which is helpful for preoperative glioma classification and evaluation of glioma microstructure and biological characteristics.

Objective: To investigate the application value of real-time virtual sonography(RVS)in the diagnosis and treatment of complicated hepatolithiasis. Methods: The retrospective and descriptive study was conducted. The clinical data of 10 patients with complicated hepatolithiasis who were admitted to Hunan Provincial People′s Hospital between October 2017 and March 2018 were collected. There were 3 males and 7 females, aged from 40 to 69 years, with an average age of 57 years. Patients received abdominal color Doppler ultrasound examination, magnetic resonance cholangiopancreatography, and upper abdominal spiral computed tomography (CT) thinly scanning + enhanced examination. Data of CT examination were imported into RVS. RVS was used to locate hepatolithiasis, relationship between stones and vessels, anatomy of bile ducts and vessels in hepatic hilus. Surgical methods included RVS-guided hilar cholangiotomy, biliary stricturoplasty, bilateral hepatojejunostomy, hepatic segmentectomy (lobectomy), and hepatolithotomy. Observation indicators: (1) surgical and postoperative situations; (2) typical case analysis; (3) follow-up. Follow-up using outpatient examination was performed to detect residual stones up to June 2019. Measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers. Results: (1) Surgical and postoperative situations: 10 patients underwent RVS-guided surgeries successfully for complicated hepatolithiasis, with successful match in RVS (difference between CT images and ultrosound images <2 mm). No residual stone was identified by choledochoscope during operation. The operation time and volume of intraoperative blood loss were 285 minutes (range, 210-360 minutes) and 200 mL (range, 100-600 mL), respectively. No blood transfusion was needed during the operations. The duration of hospital stay was 20.5 days (range, 14.0-29.0 days). There was no perioperative death. One patient had postoperative biliary leakage and abdominal infection, and was cured after conservative treatment. (2) Typical case analysis: the tenth patient, female, 60 years old, was diagnosed with complicated hepatolithiasis, and was prepared to undergo hepatolithotomy+ quadrate lobectomy and hilar cholangioplasty+ bilateral hepatojejunostomy. Preoperative CT images and intraoperative color Doppler ultrasound images of the patient were fused and matched on the sagittal section of the portal vein and the cross section of the right branch of portal vein, and stones and important vessels were marked on the images. After accurate positioning, a curette was used to remove the stones. Removal of biliary stones through hepatic parenchyma and peripheral dilated bile ducts was conducted at the site where stones obviously existed. After the stones were removed, the intrahepatic bile duct and hilar bile duct merged. The left end of the bile duct split was confirmed by real-time ultrasound. After location of portal vein was determined by ultrasound, vascular plastic surgery was perfomed to avoid stenosis. (3) Follow-up: 10 patients were followed up for 6-12 months, with a median follow-up time of 8 months. One of 10 patients was suspected residual stones at the right peripheral hepatic anterior lobe by postoperative angiography at 2 months after surgery, and was not removed stones by choledochoscope. The patient had no recurrent symptoms after T-tube removal. The other 9 patients had no residual stones. Conclusion RVS applied in complicated hepatolithiasis is helpful for the precise intraoperative diagnosis, and the surgical treatment can be safe and effective.

Objective This article retrospectively analyzed the efficacy,toxicity,survival and related factors affecting progno-sis of patients with small cell lung cancer(SCLC)who had recurrence or progression after first-course chemoradiotherapy. Methods A total of 86 patients with recurrence or progression recurrence after SCLC chemotherapy and radiotherapy from January 2007 to De-cember 2015 in Harbin Medical University Cancer Hospital were enrolled. Patients were divided into the re-treatment group to re-ceive secondary treatment with radiotherapy combined with chemotherapy and two control groups to receive secondary treatment with radiotherapy alone or chemotherapy alone. The factors affecting the prognosis of SCLC re-treatment were analyzed. The short-term and long-term efficacy,overall survival and toxicity of three groups were compared. Results The median progression-free survival time of the re-treatment group,radiotherapy group,and chemotherapy alone group was 4 months(1~20 months),2 months(1 ~7 months)and 3 months(1~6 months). There was no statistical difference(P>0. 05). The median overall survival time was 25 months (3~135 months)in the re-treatment group and 8 months in the radiotherapy group(1-59 months)and 12 months(1~108)in the chemotherapy alone group,the difference was statistically significant ( P <0. 05 ). The 1 -,2 -,and 3 -year survival rates were 73. 70% ,52. 10% and 47. 40% in the re - treatment group; 32. 90% 、 21. 90% and 21. 90% in the radiotherapy group, and 45. 40% ,19. 90% and 19. 90% in the chemotherapy alone group. The long-term effect of the re-treatment group was better than that of the radiotherapy group and the chemotherapy alone group(P<0. 05). Conclusion Re-treatment of patients with SCLC who failed after receiving radiotherapy and chemotherapy for the first time can prolong the survival time of patients and improve the life quality of patients. If the patient's physical condition permits,the treatment should be selective radiotherapy and chemotherapy as well as tolerable toxicity or side effects. Among them,patients with no distant metastasis and recurrent radiotherapy dose ≥5 000 cGy had greater survival benefit. However,the late toxic and side effects,and complications of patients after re-treatment are still to be further observed.

Objective: To evaluate the feasibility and safety of applying enhanced recovery after surgery (ERAS) protocol in patients undergoing laparoscopic distal pancreatectomy. Methods: Data of 36 patients undergoing laparoscopic distal pancreatectomy from May 2016 to May 2017 in the First Affiliated Hospital, Zhejiang University School of Medicine were reviewed. The patients were divided into ERAS group (n=12) and control group (n=24). The patients in ERAS group received a series of enhanced recovery procedures, including multimodal analgesia, early off-bed activity and early oral food-taking, etc. Operation time, intraoperative blood loss, time to first flatus, postoperative complications, and length of postoperative hospital stay were evaluated. Results: There were no statistically significant differences in operation time and intraoperative blood loss between ERAS group and control group (all P0.05). The time to first flatus and length of postoperative hospital stay were significantly shortened in ERAS group (all P<0.05). The ERAS group had lower incidence of postoperative complications (41.7% vs. 66.7%), and the complications in ERAS group tended to be milder, but the differences failed to show statistical significance (all P0.05). Conclusion: The ERAS protocol for laparoscopic distal pancreatectomy can significantly promote gastrointestinal function recovery and shorten postoperative hospital stay, and may reduce the incidence of postoperative complications.
