Transbronchil biopsy has the characteristic of less trauma and quick recovery compared to percutaneous aspiration biopsy. In order to automate this procedure, it requires the development of a robotic surgical system that combines electromagnetic navigation and flexible endoscope. The robotic surgical system introduced herein consists of flexible endoscope, remote-control handle, electromagnetic navigation and dexterous manipulators. The robotic system supports lung bronchial model segmentation and reconstruction, automatic bronchial path planning, real-time navigation and visual biopsy. In the control of the endoscopic catheter, an elasticity compensation algorithm was proposed to improve the location accuracy of the catheter and operational efficiency. Clinical trials proved that the robotic system had high positioning accuracy, was intuitive to operate, and could improve the biopsy efficiency, shorten the learning time, reduce the burden of surgical operations, and lower radiation exposure and infection rate.

Oxalicine B ( 1) is an α-pyrone meroterpenoid with a unique bispirocyclic ring system derived from Penicillium oxalicum. The biosynthetic pathway of 15-deoxyoxalicine B ( 4) was preliminarily reported in Penicillium canescens, however, the genetic base and biochemical characterization of tailoring reactions for oxalicine B ( 1) has remained enigmatic. In this study, we characterized three oxygenases from the metabolic pathway of oxalicine B ( 1), including a cytochrome P450 hydroxylase OxaL, a hydroxylating Fe(II)/α-KG-dependent dioxygenase OxaK, and a multifunctional cytochrome P450 OxaB. Intriguingly, OxaK can catalyze various multicyclic intermediates or shunt products of oxalicines with impressive substrate promiscuity. OxaB was further proven via biochemical assays to have the ability to convert 15-hydroxdecaturin A ( 3) to 1 with a spiro-lactone core skeleton through oxidative rearrangement. We also solved the mystery of OxaL that controls C-15 hydroxylation. Chemical investigation of the wild-type strain and deletants enabled us to identify 10 metabolites including three new compounds, and the isolated compounds displayed potent anti-influenza A virus bioactivities exhibiting IC₅₀ values in the range of 4.0-19.9 μmol/L. Our studies have allowed us to propose a late-stage biosynthetic pathway for oxalicine B ( 1) and create downstream derivatizations of oxalicines by employing enzymatic strategies.

The latest guideline about ulcerative colitis (UC) clinical practice stresses that mucosal healing, rather than anti-inflammation, is the main target in UC clinical management. Current mucosal dysfunction mainly closely relates to the endoscopic intestinal wall (mechanical barrier) injury with the imbalance between intestinal epithelial cells (IECs) regeneration and death, as well as tight junction (TJ) dysfunction. It is suggested that biological barrier (gut microbiota), chemical barrier (mucus protein layer, MUC) and immune barrier (immune cells) all take part in the imbalance, leading to mechanical barrier injury. Lots of experimental studies reported that acupuncture and moxibustion on UC recovery by adjusting the gut microbiota, MUC and immune cells on multiple targets and pathways, which contributes to the balance of IEC regeneration and death, as well as TJ structure recovery in animals. Moreover, the validity and superiority of acupuncture and moxibustion were also demonstrated in clinic. This study aims to review the achievements of acupuncture and moxibustion on mucosal healing and analyse the underlying mechanisms.

Glioblastoma (GBM) is the most common and aggressive malignant brain tumor in adults and is poorly controlled. Previous studies have shown that both macrophages and angiogenesis play significant roles in GBM progression, and co-targeting of CSF1R and VEGFR is likely to be an effective strategy for GBM treatment. Therefore, this study developed a novel and selective inhibitor of CSF1R and VEGFR, SYHA1813, possessing potent antitumor activity against GBM. SYHA1813 inhibited VEGFR and CSF1R kinase activities with high potency and selectivity and thus blocked the cell viability of HUVECs and macrophages and exhibited anti-angiogenetic effects both in vitro and in vivo. SYHA1813 also displayed potent in vivo antitumor activity against GBM in immune-competent and immune-deficient mouse models, including temozolomide (TMZ) insensitive tumors. Notably, SYHA1813 could penetrate the blood-brain barrier (BBB) and prolong the survival time of mice bearing intracranial GBM xenografts. Moreover, SYHA1813 treatment resulted in a synergistic antitumor efficacy in combination with the PD-1 antibody. As a clinical proof of concept, SYHA1813 achieved confirmed responses in patients with recurrent GBM in an ongoing first-in-human phase I trial. The data of this study support the rationale for an ongoing phase I clinical study (ChiCTR2100045380).

Objective: To systematically summarize and evaluate the development of update and detailed recommendations of the existing global screening guidelines in high-risk population with a family history of colorectal cancer. Methods: The words "colorectal cancer", "screening", "guideline", "consensus", "recommendations" and "family history" in Chinese and English were used as MESH terms for literature retrieval, as well as entry terms. The retrieval was performed based on China National Knowledge Infrastructure, Wanfang Data Knowledge Service Platform, PubMed, Embase, Cochrane Library and Web of Science, as well as official websites. The languages of literatures were limited in Chinese and English. As of May 24, 2022, a total of 20 valid literatures had been retrieved. The basic information of the literatures and the recommendations of colorectal cancer screening for people with family history were collected and analyzed. Results: The analysis on the 20 literatures indicated that most countries/regions/institutions recommended age range of screening, screening modalities and intervals for people with family history of colorectal cancer. For the individuals who have one first-degree relative diagnosed with colorectal cancer before 60 years of age,most guidelines recommended the screening to be started at 40 years or 10 years earlier than the age when the youngest first-degree relative was diagnosed. The most commonly recommended screening modality was colonoscopy. Conclusions: Most current screening guidelines for high-risk people with family history of colorectal cancer recommend colonoscopy as the main modality. This review will provide reference for the update of screening strategies in high-risk people with family history of colorectal cancer in China, and further improve the practices of screening, early diagnosis and treatment of colorectal cancer.

ObjectiveTo investigate the quality of Ligustri Lucidi Fructus in the market， and the moisture， extract， determination of Zhuyao and Douchi Ligustri Lucidi Fructus were compared to increase the utilization rate of Ligustri Lucidi Fructus. MethodThe properties， moisture， total ash， alcohol-soluble extract content and thin layer chromatography （TLC） identification were determined by the methods of Ligustri Lucidi Fructus included in the 2020 edition of Chinese Pharmacopoeia， and high performance liquid chromatography （HPLC） fingerprint and determination of specnuezhenide and salidroside were established with the mobile phase of 0.2% phosphoric acid aqueous solution （A）-acetonitrile （B） （0-70 min， 92%-65%A） for gradient elution， and the detection wavelength of 220 nm at 0-14 min and 225 nm at 14-70 min. The two different characters of Ligustri Lucidi Fructus were comprehensively compared by the above indicators. ResultExcept for one batch which did not meet the requirements due to the quality of harvesting， the other 12 batches of samples all met the requirements of the 2020 edition of Chinese Pharmacopoeia， but there were two different characters. Comparing the two different characters of Ligustri Lucidi Fructus， it is found that the moisture， total ash， extract， salidroside and specnuezhenide contents of Zhuyao samples were 2.22%-5.19%， 3.91%-4.49%， 32.56%-40.95%， 0.073%-0.170% and 1.45%-4.14%， and these values of Douchi samples were 3.57%-5.61%， 3.65%-4.44%， 41.31%-46.70%， 0.041%-0.067% and 3.01%-4.20%， respectively. ConclusionThe contents of extract and specnuezhenide of Douchi Ligustri Lucidi Fructus are mostly higher than those of Zhuyao Ligustri Lucidi Fructus， while the content of salidroside is lower than that of Zhuyao samples， and there are no significant differences in moisture， TLC identification and total ash content. Based on the above research， if the main purpose is to extract salidroside， it is recommended to choose Zhuyao Ligustri Lucidi Fructus. If the main purpose is to use Ligustri Lucidi Fructus as medicine， it is recommended to choose Douchi Ligustri Lucidi Fructus.

Some kinds of chronic sialadenitis were recognized during the recent years. They have specific pathogenesis, clinical and histopathologic appearances, and require specific treatment. IgG4-related sialadenitis (IgG4-RS) is one of the immune-mediated diseases, characterized by tumefactive lesions. The incidence of IgG4-RS obviously increased during the past 30 years. The study on the potential relationship between occupational exposure to chemical substances and the incidence of IgG4-RS showed that subjects with occupational exposure to agents known to cause IgG4-RD had an increased risk for IgG4-RS. Surgical excision of involved SMG could not control the disease progression, which is not recommended for treatment of IgG4-RS. The combination of glucocorticoid and steroid-sparing agents is effective for treating IgG4-RS, and restores salivary gland function. Radioiodine induced sialadenitis (RAIS) is one of the common complications of postoperative adjuvant treatment of differentiated thyroid cancer by ¹³¹I. The incidence of the disease is related to radiation dosage. Clinically, the patients suffered from swelling and tenderness in the buccal or submandibular regions, especially during the mealtime. Imaging appearances are similar to those of chronic obstructive sialadenitis. Conservative managements, such as gland massage, sialagogues, are the mainstream methods in the treatment of RAIS. Sialendoscopy is feasible for RAIS, but not as effective as conventional obstructive sialadenitis (COS). Therefore the prevention of RAIS is crucial. Eosinophilic sialodochitis (ES) is a new type of chronic inflammatory disease of the salivary gland related to allergy. It has characteristics of swelling of multiple major salivary glands, strip-like gelatinous plugs discharged from the duct orifice of the gland, elevated level of serum IgE and eosinophils in peripheral blood, infiltration of eosinophils and IgE positive plasma cells in the tissues, allergic history, increased expression of allergy-related cytokines, such as IL-4, IL-5, IL-13, and eotaxin, which suggest allergic reactions as a potential pathogenesis of the disease. The clinical, laboratory, histological, and immunohistochemical characteristics of ES are significantly different from conventional obstructive sialadenitis (COS). Therefore, it is suitable to separate ES from COS. Conservative managements, such as self-maintenance therapy and anti- allergic modality are the choices of treatment for ES. Based on the results of our comprehensive studies a new classification of chronic sialadenitis is suggested.
