Endodontic diseases are a kind of chronic infectious oral disease.Common endodontic treatment concepts are based on the removal of inflamed or necrotic pulp tissue and the replacement by gutta-percha.However,it is very essential for endodontic treatment to debride the root canal system and prevent the root canal system from bacterial reinfection after root canal therapy(RCT).Recent research,encompassing bacterial etiology and advanced imaging techniques,contributes to our understanding of the root canal system's anatomy intricacies and the technique sensitivity of RCT.Success in RCT hinges on factors like patients,infection severity,root canal anatomy,and treatment techniques.Therefore,improving disease management is a key issue to combat endodontic diseases and cure periapical lesions.The clinical difficulty assessment system of RCT is established based on patient conditions,tooth conditions,root canal configuration,and root canal needing retreatment,and emphasizes pre-treatment risk assessment for optimal outcomes.The findings suggest that the presence of risk factors may correlate with the challenge of achieving the high standard required for RCT.These insights contribute not only to improve education but also aid practitioners in treatment planning and referral decision-making within the field of endodontics.

Objective:To evaluate the optimization efficacy of pressure-volume (P-V) curve-based individualized lung-protective ventilation strategy combined with pressure-controlled ventilation-volume guaranteed (PCV-VG) mode (LPVS+ PCV-VG) for one-lung ventilation (OLV) in elderly patients undergoing radical resection of lung cancer.Methods:Seventy American Society of Anesthesiologists Physical Status classificationⅡ-Ⅲ patients, aged 65-74 yr, with body mass index of 18-24 kg/m 2, undergoing elective thoracoscopic radical resection of lung cancer, were divided into 2 groups ( n=35 each) using a random number table method: PCV-VG group and LPVS+ PCV-VG group. Blood samples were collected from the radial artery for blood gas analysis before induction of general anesthesia (T 0), at 5 min of two lung ventilation after endotracheal intubation (T 1), at 30 min of OLV (T 2), at the end of OLV (T 3), and at 5 min of two lung ventilation in supine position (T 4). Ppeak, mean airway pressure (Pmean) and dynamic lung compliance (Cdyn) were recorded. The use of antibiotics, lung-related complications and rehabilitation were recorded within 7 days after operation. Results:Compared with PCV-VG group, PaO 2, PaCO 2 and Cdyn were significantly increased at T 2-4, Ppeak was decreased at T 2, 3, Pmean was increased at T 3, the requirement for antibiotics within 7 days after operation was decreased, the incidence of 1 grade lung-related complications was decreased, and the thoracic drainage tube indwelling time and length of hospital stay were shortened in LPVS+ PCV-VG group ( P<0.05). Conclusions:Individualized LPVS based on P-V curve combined with PCV-VG mode provides better efficacy for OLV in elderly patients undergoing radical resection of lung cancer.

The growth environment of medicinal plants plays an important role in the formation of their medicinal quality. However, there is a lack of combined analysis studying the close relationship between the growth environment, chemical components, and related biological activities of medicinal plants. Therefore, this study investigated the effect of different soil moisture treatments on the efficacy to eliminate dampness and relieve jaundice and the flavonoid content of Sedum sarmentosum, and explored their correlation. The flavonoid content in the decoction of S. sarmentosum growing under field conditions with soil moisture levels of 35%-40%(T1), 55%-60%(T2), 75%-80%(T3), and 95%-100%(T4) was compared. The effects of these treatments on liver function parameters, liver inflammation, and oxidative damage in mice with dampness-heat jaundice were evaluated, and the correlation between pharmacological indicators and flavonoid content was analyzed. The results showed that the total flavonoid and total phenolic acid content in the decoction of S. sarmentosum were highest in the T1 treatment, followed by the T3 treatment. The content of quercetin, kaempferol, and isorhamnetin was highest in the T2, T1, and T3 treatments, respectively. Among the different moisture treatments, the T3 group of S. sarmentosum effectively reduced the levels of serum ALT, AKP, TBIL, DBIL, TBA, as well as hepatic TNF-α and IL-6 in mice with jaundice, followed by T2 treatment, especially in reducing AST level. The T4 treatment had the poorest effect. Correlation analysis showed a significant negative correlation between AST, ALT, AKP levels in mice and the total content of quercetin and the three flavonoids. MDA showed a significant negative correlation with the total flavonoid content and kaempferol. TNF-α exhibited a significant negative correlation with the content of isorhamnetin. In conclusion, S. sarmentosum growing under field conditions with a soil moisture level of 75%-80% exhibited the best efficacy to eliminate dampness and relieve jaundice. This study provides insights for optimizing the cultivation mode of medicinal plants guided by pharmacological experiments.

HSP90 is a widely distributed molecular chaperone that participates in a variety of cellular processes and plays an important role in the meiosis of germ cells. However, its role in the gonadal development of hermaphroditic Whitmania pigra is not yet clear. To explore the effect of HSP90 on the germ cell development of Wh. Pigra, this study cloned the wpHSP90 gene, performed bioinformatics analysis, and measured its expression levels. The results showed that the cloned wpHSP90 was 2 592 bp in length, with an open reading frame(ORF) of 2 373 bp, encoding 790 amino acids. Prediction analysis revealed 85 phosphorylation modification sites on serine, threonine, and tyrosine residues of the wpHSP90 protein. Structural domain prediction and multiple sequence alignment results showed that wpHSP90 contained two conserved domains of HSP90 and exhibited the highest homology with Helobdella robusta, with a sequence similarity of 80.72%. RT-qPCR results showed that the relative expression level of wpHSP90 in the gonads of 5-month-old Wh. pigra was positively correlated with temperature within the range of 12 ℃ to 28 ℃. The expression level in the female gonads was significantly higher than in the male gonads and correlated with the trend of germ cell development in the ovaries and testes. In conclusion, wpHSP90 may be involved in regulating the development of germ cells, particularly oocytes, in Wh. pigra. This study provides a reference for further research on the gonadal development mechanism in Wh. pigra.

Abstract: Mycobacterium senegalense is one of the major pathogens causing bovine farcy, and reports of its infection in human are rare. Here is a report on a woman who had been taking hormones and immunosuppressants for a long time for SLE and underwent abdominal soft tissue infection with Mycobacterium senegalense after abdominal liposuction, to provide reference for clinical diagnosis and treatment. The patient, female, 32 years old, has a history of SLE for more than 2 years, and currently takes "methylprednisolone, hydroxychloroquine, and mycophenolate mofetil" regularly. Nine months before the patient was admitted to the hospital, she once performed abdominal, waist and buttock liposuction in a medical beauty institution. One month after the operation, several masses gradually appeared on the abdominal wall, accompanied by tenderness, one of the masses had obvious fluctuation on palpation and purulent fluid could be drawn out. The location of the abdominal wall mass was consistent with the insertion site of the liposuction needle. After the onset of the disease, the patient went to the medical beauty institution for puncture of the abdominal wall mass, and 5 mL of purulent fluid was pierced and sent for bacterial culture, and cultured "Mycobacterium Senegalense", after 3 days of treatment with "cephalosporin" antibiotics (specifically unknown), the symptoms did not improve, so she went to the second affiliated hospital of hainan medical college. After completing the relevant examinations during the hospitalization in our hospital, in order to clarify the etiology, another abdominal puncture to extract pus was performed, the mycobacterial culture + identification results: Mycobacterium senegalense. Consistent with the out-of-hospital results, the diagnosis of Mycobacterium senegalense infection was confirmed. After 3 months of treatment with "cefoxitin, azithromycin, amikacin, and levofloxacin", the patient's abdominal wall soft tissue infection was cured. Trauma or invasive procedures can lead to skin, muscle, or bone infection with nontuberculous mycobacteria (NTM), which can manifest as chronic painless nodules that progress to purulent folliculitis and abscesses. NTM infection should be suspected when the patient's wound has been exposed to water, there is a history of surgery, and empirical anti-infection is ineffective. This is the first case of Mycobacterium senegalense infection caused by medical beauty, which tell people that they should be cautious when choosing medical aesthetic projects and medical aesthetic institutions.

Background/Aims: Single-balloon enteroscopy (SBE) has been widely used in diagnosing small bowel disease. We conducted this study to systematically appraise its technical and clinical performance. Methods: Studies on SBE published by September 2018 were systematically searched. Technical and clinical performance data were collected and analyzed with descriptive or meta-analysis methods. Results: In total, 54 articles incorporating 4,592 patients (6,036 procedures) were included. Regarding technical parameters, the pooled insertion depths (IDs) for anterograde and retrograde SBE were 209.2 cm and 98.1 cm, respectively. The pooled retrograde ID in Asian countries was significantly greater than that in Western countries (129.0 cm vs 81.1 cm, p<0.001). The pooled anterograde and retrograde procedure times were 57.6 minutes and 65.1 minutes, respectively.The total enteroscopy rate was 21.9%, with no significant difference between Asian and Western countries. Clinically, the pooled diagnostic yield of SBE was 62.3%. Obscure gastrointestinal bleeding (OGIB) was the most common indication (50.0%), with a diagnostic yield of 59.5%. Vascular lesions were the most common findings in Western OGIB patients (76.9%) but not in Asian ones (31.0%). The rates of severe and mild adverse events were 0.5% and 2.5%, respectively. Conclusions SBE is technically efficient and is clinically effective and safe, but total enteroscopy is relatively difficult to achieve with this technique. Etiologies of OGIB in Asian countries differ from those in Western countries.
