, while CA 19-9 level was not an independent factor (OR=1.873, 95% CI0.372-9.436, P=0.447). Conclusion By knowing the clinical features of preoperative T stage, tumor circumference, tumor morphology and the interval between neoadjuvant chemoradiotherapy and operation, patients with higher likelyhood of pCR after neoadjuvant chemoradiotherapy may be identified.The combination of artificial intelligence (AI) technology and medicine is an important milestone in the development of modern medicine, which realizes the digitalization and intelligence for clinicians in the process of diagnosis and treatment. This is not a competition between human and machine, but a collaborative progress and development. The incidence of colorectal cancer remains high in China. The introduction of AI technology in lymph node metastasis, circumferential resection margin, neoadjuvant therapy, genetic diagnosis, radiomics, pathological assistance and colonoscopy diagnosis has further improved the diagnosis and treatment, as well as the evaluation and prediction of the disease of colorectal cancer. This article will review and comment on the application of AI technology in colorectal cancer staging, neoadjuvant therapy, gene diagnosis, pathological assistance and other aspects.Anastomotic bleeding is a common complication after colorectal surgery, mainly manifesting as continuous or intermittent bloody stool. The risk factors for anastomotic bleeding mainly include suboptimal surgical skill, surgical methods (such as laparoscopic anastomosis), close distance between the tumor and the anal margin, benign colorectal diseases, anastomotic leakage after colorectal surgery, severe pelvic and abdominal infections, and the patient's own condition, etc. Anastomotic bleeding can be prevented by standardized operation and intraoperative endoscopic examination. Anastomotic bleeding is mostly a self-limited disease, which can be cured by conservative treatments such as fluid resuscitation, blood transfusion and endoscopic treatment. When serious anastomotic bleeding threatens the life of patients, surgical treatment should be taken into consideration decisively.Colorectal surgeons have focused on the lateral structure of rectum for a long time and lateral ligament is the common term to depict this structure. A better understanding of lateral rectal structure could be beneficial to performing the total mesorectum excision (TME) procedure and protecting patients' urinary, sexual and defecation function. The main controversies focus on two aspects (1) Does the lateral ligament exist? (2) What dose it contain? Does the middle rectal artery exist? Up to now, anatomic studies have failed to reach consensus on the lateral rectal structure. However, surgeons do find the lateral rectal ligament during surgery and it may be the pathway for lateral lymph node metastasis in rectal cancer. The lateral rectal structure contains the middle rectal artery, nerve branches, lymphatics and adipose fibrous tissue around them. We summarize our clinical experience and conclude that the middle rectal artery appears in lateral ligament constantly but some of them are too small to be easily observed. Therefore, regarding the perspective of membrane anatomy, embryology and surgery, this structure may be more appropriate to be called the "lateral mesorectum". PRGL493 cost We propose this new term based on the previous literature and our own experience for the readers' reference.Surgical resection remains the only curative therapy for colorectal adenocarcinoma and liver metastasis. Synchronous robotic resection for colorectal liver metastasis (CRLM) offers the advantage of avoiding double surgical stress, while providing the benefits of small incision, quicker recovery, shorter hospital stay and faster postoperative adjuvant therapy. Compared with the laparoscopic approach, robotic approach is mostly suitable for rectal cancer liver metastasis, which is associated with low conversion rate, good nerve protection, high success rate for major hepatectomy and resection of difficult segments. Appropriately selected patients, multidisciplinary cooperation and skillful robotic surgeons are the key to success. Current data have demonstrated the feasibility and safety of synchronous robotic resection for CRLM. With the coming randomized controlled trial data and evolution of robotic surgical system, the future of synchronous robotic resection for colorectal liver metastasis is promising.Prolapsed hemorrhoids is a common clinical disease, and severe symptoms can significantly affect work and life. The transanal stapler has the advantages of simple operation and less trauma in treating prolapsed hemorrhoids. Its clinical efficacy is closely related to the selection of indications, the standardization of surgical operations, and the prevention and treatment of complications. In current clinical practice, there is no consensus on the treatment of prolapsed hemorrhoids with transanal stapler. Hence a discussion was held by the Professional Committee of Colorectal Diseases of Chinese Society of Integrated Chinese and Western Medicine, concerning the indications, contraindications, operating specifications and perioperative management of prolapsed hemorrhoids. A consensus was consequently formed, aiming to provide a guideline for the clinical practice.The significant increase in the incidence of benign anal diseases is related to the fast-paced life style, the change of dietary structure, the increase of work pressure and social psychological factors. Surgery is one of the most important treatments for benign anal diseases, while perioperative defecation management is closely related to the efficacy of surgery. In current clinical practice, there is no consensus on the management of perioperative defecation for benign anal diseases. Hence a discussion was held by the Professional Committee of Colorectal Diseases of Chinese Society of Integrated Chinese and Western Medicine, concerning the causes of perioperative defecation difficulties in perioperative anal benign diseases, the importance and specific strategy of defecation management. A consensus was consequently formed, aiming to provide a guideline for the clinical practice.Anal fistula is one of the most common diseases in colorectal and anal surgery. link2 Most of them are formed after the abscess of perianal space reptures. Due to the complexity and diversity of pathological changes, the clinical efficacy of some patients is not optimistic, and there may even be serious surgical complications, including delayed healing of anal fistula or varying degrees of fecal incontinence, which significantly affect the quality of life of patients and even lead to disability. The Working Committee of Clinical Guidelines of Anorectal Physicians Branch of Chinese Medical Association organized some domestic experts to discuss and prepare this expert consensus. It is suggested that comprehensive evaluation of anal fistula, including detailed medical history, physical examination and necessary auxiliary examination should be conducted before treatment. Auxiliary examinations include fistulography, ultrasound, CT or MRI. The purpose of the auxiliary examination is to accurately determine the position e of anal fistula. Because there is a certain risk of recurrence and fecal incontinence after anal fistula surgery, for some patients with complex condition, repeated operations or impaired anal function, we must be careful when choosing reoperation, and weigh the benefits of patients and the risk of fecal incontinence.Co-occurrence of pneumothorax and pneumomediastinum is rare in COVID-19 patients. Positive airway pressure therapy used to improve oxygenation may sometimes worsen clinical outcomes in some patients with severe COVID-19 pneumonia. In this case report, we describe an individual who was diagnosed with COVID-19 and developed bilateral pneumothorax and pneumomediastinum after initiating non-invasive positive airway pressure therapy.The source of funding should be modified in our original article [...].Countercurrent liquid-liquid chromatographic techniques (CCC), similar to solvent extraction, are based on the different distribution of compounds between two immiscible liquids and have been most widely used in natural product separations. link3 Due to its high load capacity, low solvent consumption, the diversity of separation methods, and easy scale-up, CCC provides an attractive tool to obtain pure compounds in the analytical, preparative, and industrial-scale separations. This review focuses on the steady-state and non-steady-state CCC separations ranging from conventional CCC to more novel methods such as different modifications of dual mode, closed-loop recycling, and closed-loop recycling dual modes. The design and modeling of various embodiments of CCC separation processes have been described.CDAP (1-cyano-4-dimethylaminopyridine tetrafluoroborate) is employed in the synthesis of conjugate vaccines as a cyanylating reagent. In the published method, which used pH 9 activation at 20 °C (Vaccine, 14190, 1996), the rapid reaction made the process difficult to control. Here, we describe optimizing CDAP activation using dextran as a model polysaccharide. CDAP stability and reactivity were determined as a function of time, pH and temperature. While the rate of dextran activation was slower at lower pH and temperature, it was balanced by the increased stability of CDAP, which left more reagent available for reaction. Whereas maximal activation took less than 2.5 min at pH 9 and 20 °C, it took 10-15 min at 0 °C. At pH 7 and 0 °C, the optimal time increased to >3 h to achieve a high level of activation. Many buffers interfered with CDAP activation, but DMAP could be used to preadjust the pH of polysaccharide solutions so that the pH only needed to be maintained. We found that the stability of the activated dextran was relatively independent of pH over the range of pH 1-9, with the level of activation decreased by 40-60% over 2 h. The use of low temperature and a less basic pH, with an optimum reaction time, requires less CDAP, improving activation levels while making the process more reliable and easier to scale up.This review summarizes the research on phospholipids and their use for drug delivery related to the Phospholipid Research Center Heidelberg (PRC). The focus is on projects that have been approved by the PRC since 2017 and are currently still ongoing or have recently been completed. The different projects cover all facets of phospholipid research, from basic to applied research, including the use of phospholipids in different administration forms such as liposomes, mixed micelles, emulsions, and extrudates, up to industrial application-oriented research. These projects also include all routes of administration, namely parenteral, oral, and topical. With this review we would like to highlight possible future research directions, including a short introduction into the world of phospholipids.The risk of reseeding malignancy harbored in cryopreserved and transplanted ovarian tissue has been a source of concern. This study aimed to determine the potential relationship between frozen-thawed ovarian tissue transplantation and primary cancer recurrence. Three patients with cerebral primitive neuroectodermal tumors (PNET) were included in this study. One woman gave birth to three healthy babies following reimplantation of her cryopreserved ovarian tissue, but subsequently died due to cancer relapse six years after ovarian tissue transplantation. The second subject died from progressive cancer, while the third is still alive and awaiting reimplantation of her ovarian tissue in due course. Frozen ovarian cortex from all three patients was analyzed and xenotransplanted to immunodeficient mice for five months. Main outcomes were the presence of cancer cells in the thawed and xenografted ovarian tissue at histology, immunostaining (expression of neuron-specific enolase and glial fibrillary acidic protein (GFAP)), and reverse-transcription droplet digital polymerase chain reaction (RT-ddPCR) (levels of enolase 2 and GFAP).
