Baihe Dihuangtang is a famous classical formula that has been respected by physicians in the past and is still used today. It was first recorded in ZHANG Zhongjing's Synopsis of the Golden Chamber， and is composed of Lilii Bulbus and Rehmanniae Radix juice. This paper systematically reviewed the research progress of historical evolution， pharmacological activities and clinical applications of Baihe Dihuangtang in recent years， and found that there was no major changes in the composition， decoction method and indications of this formula since the Han dynasty. According to the herbal textual research， the fleshy scaly leaves of Lilium brownii var. viridulum should be selected for Lilii Bulbus in this formula， and the tuberous roots of Rehmannia glutinosa were selected for Rehmanniae Radix. According to the dosage conversion of ancient and modern times， the dosage is 245 g of fresh Lilii Bulbus and 400 g of fresh Rehmanniae Radix， and the ratio of their juice is 1∶1. Its efficacy is to nourish Yin and clear heat， and to tonify the heart and lungs， which is used to treat the heart and lung Yin deficiency syndrome of lily disease. Modern pharmacological studies have shown that the research on the pharmacological effects of Baihe Dihuangtang mainly focuses on anti-depressant， anti-anxiety， improving insomnia and regulating metabolism， and it is mostly used clinically for neurological disorders such as depression， anxiety and insomnia. The quality marker（Q-Marker） of Baihe Dihuangtang were predicted according to the principles of ingredient specificity， component validity， component measurability， formula compatibility， and quality transmissibility and traceability， and it was determined that catalpol， rhmannioside D， regaloside A， regaloside B， regaloside C， and acteoside could be selected as potential Q-Markers of Baihe Dihuangtang， which could provide scientific reference for the establishment of the quality control system and the development of compound preparation of this famous classical formula.

Objective To compare the detection rates of X-ray,ultrasound,computed tomography(CT)and cone beam CT(CBCT)for submandibular gland calculi in different positions,and to explore the auxiliary value of 3-dimensional visualization technology in diagnosis and treatment of submandibular gland calculi.Methods The X-ray,ultrasound,CT and CBCT examination data of 113 patients with submandibular gland calculi at General Hospital of Ningxia Medical University from Nov.2014 to Mar.2021 were retrospectively analyzed.The detection rates and overall detection rates of the 4 imaging methods for calculi in different positions were compared.Mimics 19.0 software and CBCT data were used for 3D reconstruction imaging,visually displaying the location,size,morphology,and number of calculi from a visual perspective.Results There was no significant difference in the total detection rate of submandibular gland calculi between CBCT and CT(98.2％[111/113]vs 95.6％[108/113],P＞0.05),but both were significantly higher than that of X-ray(65.5％,74/113)and ultrasound(73.5％,83/113).The detection rates of ultrasound for calculi in the anterior and middle ducts were the lowest(63.6％[21/33]and 72.2％[26/36],respectively),which were significantly different from those of CBCT(97.0％[32/33]and 100.0％[36/36],respectively)and CT(93.9％[31/33]and 97.2％[35/36],respectively)(all P＜0.05).The detection rate of X-ray for calculi in the posterior duct was significantly lower than that of ultrasound,CBCT,and CT(40.9％[18/44]vs 81.8％[36/44],97.7％[43/44],and 95.5％[42/44],all P＜0.01).After CBCT data were imported into Mimics 19.0 software,submandibular gland calculi with different sizes,shapes,or numbers were successfully visualized and reconstructed.The reconstructed image was clear,and anatomical position relationship between the calculi and the mandible was visualized.Conclusion CBCT has good application value in the diagnosis of submandibular gland calculi and can replace traditional CT for the diagnosis of sialolithiasis.Clinically,CBCT examination can be directly performed for accurate diagnosis of calculi in the posterior duct which are not detected by double coincidence diagnosis but are indicated by ultrasound.For calculi in the anterior and middle ducts,X-ray and CBCT are preferred.Visualization technology helps clinical patient education and the development of personalized preoperative treatment plans.

Objective:To study the clinical characteristics and risk factors for hypertriglyceridemia-induced severe acute pancreatitis (HTG-SAP) complicated by acute kidney injury.Methods:The clinical data of HTG-SAP patients admitted to the Department of Critical Care Medicine of the Second Affiliated Hospital of Anhui Medical University from January 2014 to July 2022 were retrospectively collected, and divided into an AKI group and a non-AKI group according to whether AKI occurred. The general condition, laboratory data and clinical characteristics of the two groups were compared. Factors with statistically significant differences were screened for logistic regression analysis and a predictive model was constructed. We plotted the receiver operating characteristic curve and used the area under the curve (AUC) to evaluate the predictive ability of each predictor for HTG-SAP complicated with AKI.Results:A total of 91 patients were included, including 37 (40.7%) with AKI and 54 (59.3%) without AKI. The proportions of extrapancreatic infection, sepsis and multiple organ dysfunction syndrome, requiring mechanical ventilation, continuous renal replacement therapy (CRRT), retroperitoneal puncture, and surgical intervention were higher in the AKI group than in the non-AKI group (all P<0.05). The length of ICU stay, total length of hospitalization, and mortality rate in the AKI group were higher than those in the non-AKI group (all P<0.05). Multivariate logistic regression analysis showed that acute physiology and chronic health status scoreⅡ (APACHEⅡ) ( OR=2.069, 95% CI: 1.286-3.417, P=0.003), abdominal pressure ( OR=1.469, 95% CI: 1.108-1.958, P=0.007), and lactic acid ( OR=3.156, 95% CI: 1.013-9.831, P=0.047) were independent risk factors for AKI in HTG-SAP patients. The AUCs of the APACHEⅡ score, abdominal pressure, lactic acid level and combined prediction model were 0.951, 0.918, 0.837 and 0.986, respectively. Conclusions:Patients with HTG-SAP complicated with AKI were more likely to have complications related to extrapancreatic infection, sepsis and multiple organ dysfunction, and the proportion of mechanical ventilation, CRRT, retroperitoneal puncture and surgical intervention required during hospitalization was greater, the lengths of ICU stay and total hospital stay were longer, and the mortality rate was higher. APACHEⅡ score, abdominal pressure and lactic acid were independent risk factors for HTG-SAP concurrent AKI, and the prediction model established based on these three factors had higher value in predicting HGT-SAP concurrent AKI

Objective:To study the clinical effect of different application times of antibiotics in patients with hypertriglyceridemic severe acute pancreatitis(HTG-SAP).Methods:The clinical data of 92 patients with HTG-SAP who were treated at the Department of Critical Care Medicine of the Second Affiliated Hospital of Anhui Medical University from January 2016 to February 2022 were analyzed retrospectively. There were 65 males and 27 females, aged (40.82±10.55) years old. These patients were divided into three groups based on the time of prophylactic use of antibiotics: the early prevention group (used within 72 h after admission, n=39), the delayed prevention group (used after 72 h after admission, n=30) and the nonprevention group ( n=23). The clinical data such as the general data, length of stay and all cause mortality rate of the three groups of patients were analyzed. Results:Compared with patients in the nonprevention group, the incidence rate of pancreatic/peripancreatic infection [10.0%(3/30) vs. 39.1%(9/23)] and the incidence rate of bloodstream infection [6.7%(2/30) vs. 34.8%(8/23)] in the delayed prevention group were significantly decreased (pancreas/peripancreatic infection: χ 2=6.31, P=0.012; bloodstream infection: χ 2=6.72, P=0.010). The infection rate of multiple/pan resistant bacteria in the early prevention group [23.1%(9/39)] was significantly higher than the nonprevention group [4.3%(1/23)] (χ 2=4.49, P=0.034). There were no significant differences in the all cause mortality rate, length of stay, duration of intensive care, hospitalization cost, incidence of intestinal fistula and retroperitoneal hemorrhage, and the proportion of patients requiring surgery among the 3 groups (all P>0.05). Conclusions:Pophylactic use of antibiotics within 72 h of hospital admission significantly reduced the incidence of pancreatic/peripancreatic infection and bloodstream infection in patients with HTG-SAP. There were no significant differences in the final prognosis among these patients with HTG-SAP treated with antibiotics at different times.

Objective To quantify operation characteristics of the ankle rotating-traction-poking manipulation (RTPM) for treating acute lateral ankle sprain by using motion capture technology, so as to provide objective references for standardized operation of RTPM and its education inheritance. Methods A professional physiotherapist performed the RTPM on 60 volunteers with acute lateral ankle sprain. Motion capture system was used to acquire effective kinematic data during the RTPM, so as to make analysis and summarize rules. Results The average time of ankle rotating for six circles was 11.36 s and the average time of ankle traction and poking was 3.42 s. The average displacement of ankle traction was 36.94 mm and the average displacement of ankle poking was 22.44 mm. The average angle of ankle traction was 23.27°, and the average angle of ankle poking was 22.76°. During the RTPM for treating acute lateral ankle sprain, the average linear velocity of ankle rotating was 58.28 mm/s, and the average linear velocity of ankle traction and poking was 23.81 mm/s. The linear acceleration of ankle rotating was 0.43 mm/s2, and the linear acceleration of ankle traction and poking was 0.54 mm/s2. Conclusions The RTPM can be applied in clinical practice. During the RTMP, the principle of gentleness, rhythmicity and continuity should be followed. Under the premise of following physiological characteristics of ankle joint, treatment of the sprained ankle should be carried out with slow and uniform speed continuously.

OBJECTIVE：To explo re the potential molecular mechanism of ursolic acid in the treatment of osteoporosis （OP）. METHODS：TCMSP，PubMed database and UniProt database were used to screen potential targets of monomer compound ursolic acid. OP related target genes were searched with GeneCards database. The common target genes of component-disease were obtained by Venny 2.1 online mapping tool. The protein-protein interaction （PPI）network of component-disease common target genes was constructed by using STRING database ，and topological analysis was carried out ；the core target genes ，whose degree value was greater than the average degree value ，were screened. GO functional annotation and KEGG pathway enrichment analysis of component-disease common target genes were carried out by DAVID database. AutoDock Vina 1.1.2 software was used for molecular docking ，using protein encoded by the core target gene as receptor and ursolic acid as ligand. RESULTS ：A total of 55 ursolic acid related target genes and 4 273 OP related target genes were excavated ，with a total of 44 common target genes. PPI network with above common target genes included 44 nodes and 513 edges，with an average node degree of 23.3. There were 24 core target genes ，including VEGFA，TP53，IL6，CASP3. There were 340 GO functional items were enriched （corrected P＜ 0.05），including 263 biological processes （negative regulation of apoptosis ，etc.），25 molecular functions （protein binding ，etc.） and 52 cell components （cytosol，etc.）. There were 90 KEGG signaling pathways （corrected P＜0.05），such as tumor pathway ， hepatitis B pathway ，TNF signaling pathway ，viral carcinogenesis and phosphatidylinositol 3 kinase/protein kinase B （PI3K-Akt） signaling pathway. The binding energy between ursolic acid and 6 proteins encoded by core target genes such as TP53 was lower than －5 kcal/mol，which had strong binding activity. CONCLUSIONS ：The therapeutic effect of ursolic acid on OP may be achieved by regulating VEGFA，TP53，IL6，CASP3，JUN and other core target genes and acting on multiple key pathways such as cancer pathway ， hepatitis B and TNF signaling

Objective: To evaluate the clinical effects of CGF membrane for repairing the oral mucosa defects. Methods: 39 patients were selected with oral mucosa defects after surgical resections. 19 defects were covered by autologous CGF membranes as the experimental group. 20 defects were not covered by membrane as the control group. Regular follow-up were performed at one week, two weeks, three weeks, one month, two months, three months after the operations. And wound healings were compared in the groups. Results: CGF membranes of the 19 patients in the experimental group survived completely. And no infection occurred. The wound healing rate of the experimental group was higher than that of the control group at two weeks, three weeks and one month after the operations. And the difference was statistically significant(P<0.05). The VAS score of the experimental group was lower than that of the control group at one week, two weeks, three weeks and one month(P<0.05). The mean score of VSS score in the experimental group was lower than that in the control group (P<0.05). Conclusions Repair of the oral mucosa defects with CGF membrane can shorten the period of wound healing, relieve the postoperative discomfort and reduce the scar. It was a safe and effective method worthy to be popularized.

Objective To examine the sleep status and relevant psychosocial factors in patients with colorectal cancer before surgery and improve their sleep quality. Methods A cross?sectional survey method was used. Participants were 107 cases of patients with colorectal cancer from the Department of Anorectal Surgery in The First Hospital ,which is affiliated with China Medical University. The Athens insomnia scale(AIS),Ham?ilton depression scale(HAMD),Hamilton anxiety scale(HAMA),perceived social support scale(PSSS),self?esteem scale(SES),medical cop?ing questionnaire(MCMQ),memorial University of Newfoundland scale of happiness(MUNSH),Eysenck personality questionnaire(EPQ),and Wong?Baker face scale were used to assess preoperative sleep in patients with colorectal cancer and related psychosocial factors. Results Among the 107 cases,there were 24 cases of insomnia,with an insomnia incidence of 22.43%. No statistical differences were found in demographic charac?teristics and clinical characteristics(P>0.05). According to the degree of insomnia,there were significant differences between groups(P<0.05) for depression,anxiety,social support,avoidance,yield,happiness,and EPQ?N. Before the surgery,the degree of depression,anxiety,and EPQ?P had a significant positive effect on the degree of insomnia (P< 0.05). Conclusion The degree of insomnia before surgery in patients with colorectal cancer is closely associated with depression,anxiety,coping styles,social support,and personality characteristics.

Background and purpose: The previous work of this study has showed that the treatment of liver cancer cells with emodin could induce endoplasmic reticulum (ER) stress and apoptosis. Given the cross-talk between ER stress and autophagy, this study aimed to investigate whether blockage of autophagy, a defense mechanism against environmental stress, could improve the killing effect of emodin on liver cancer cells. Methods: The CYTO-ID auto-phagy detection kit and Western blot were used to determine autophagy in liver cancer cells. After combined treatment with chloroquine (CQ) and emodin, cancer cell survival was analyzed by ATPlite assay and clonogenic assay. Apoptosis was detected by both flow cytometry analysis and Western blot. Results: Autophagy could be induced in liver cancer cells after treatment with emodin. Inhibition of autophagy significantly increased growth-inhibitory effect of emodin on both HepG2 and Huh7 cancer cells. The combination treatment with CQ and emodin promoted remarkable apoptosis in liver cancer cells, evidenced by the increase in the percentage of cells in sub-G1 phase and the higher expression lever of cleaved caspase-3. Conclusion: Therapeutically targeting autophagy is capable of enhancing cytotoxicity of emodin in liver cancer cell lines.

Objective To investigate the expression and relationship between Phosphatase and tension homolog deleted on chromosome ten (PTEN) and Alpha fetoprotein(AFP) in hepatocellular carcinoma. Methods PTEN and AFP expression was examined by immunohistochemical method. Results PTEN expression was significantly weaker in patients with tumor less than 5.0 cm and patients with CLIP score≥1 (P<0.05). The expression of PTEN and AFP was negatively correlated ( Rs=-0.422, P=0.043), serum AFP and tissue expression of AFP was positively correlated (Rs=0.380, P=0.042), but for individual expression was not consistent. Conclusions PTEN and AFP is respectively negative and positive adjustment factor of PI3K/AKT pathway. Tissue expression of AFP may be more significant, and may become the new targets for the treatment of hepatocellular carcinoma.
