Exploring the Pathogenesis of T2DM based on the Correlation between “Qi-fire Imbalance” and Ferroptosis / 中医杂志

Ferroptosis is a novel iron-dependent mode of programmed cell death characterized by iron deposition and accumulation of lipid peroxidation. More and more studies have found that ferroptosis is closely related to the pathogenesis of type 2 diabetes mellitus （T2DM）. The yin-fire theory is an important part of LI Gao's spleen-stomach theory， and it is believed that qi-fire imblance and yin-fire internal generation is the main pathogenesis of T2DM. Abnormal iron metabolism may be an important prerequisite for T2DM yin-fire internal generation， while oxidative stress is the specific manifestation of T2DM qi-fire imbalance. Reactive oxygen species （ROS） is the end product of qi-fire imbalance， and lipid peroxide is the pathological products of T2DM yin-fire internal generation. This study intends to explore the pathological mechanism of qi-fire imbalance and yin-fire internal generation from the perspectives of iron metabolism， oxidative stress and lipid peroxidation， enriching the modern connotation of yin-fire theory， and benefiting traditional Chinese medicine to target against ferroptosis， and prevent and treat T2DM precisely.

A technique of "de-sharpening" intramedullary elastic reduction with Kirschner wire for the treatment of Gartland type III posterolaterally-displaced supracondylar humerus fracture in children / 中华创伤杂志

Objective:To compare the clinical effect of "de-sharpening" intramedullary elastic reduction with Kirschner wire and traditional three-dimensional manipulation for the treatment of Gartland type III posterolaterally-displaced supracondylar humerus fracture in children.Methods:A retrospective cohort analysis was made on 106 children with Gartland type III posterolaterally-displaced supracondylar humerus fracture treated in Anhui Provincial Children′s Hospital from March 2020 to June 2022, including 58 males and 48 females; aged 1-12 years [(8.7±2.3)years]. The patients were assigned to "de-sharpening" intramedullary elastic reduction with Kirschner wire (study group, n=50) and traditional three-dimensional manipulation (control group, n=56). The operation time, frequency of intraoperative fluoroscopy, fracture healing time, difference of Baumann angle between the normal and injured side at postoperative 3 and 6 months, elbow function Flynn score at last follow-up and complications were compared between the two groups. Results:All children were followed up for 6-12 months [(8.5±1.2)months]. The operation time and frequency of intraoperative fluoroscopy were (32.9±3.7)minutes and (20.6±5.4)times in study group, significantly different from (45.6±10.1)minutes and (32.5±8.2)times in control group (all P<0.05). The fracture healing time was (33.0±5.1)days in study group, similar with (33.8±4.7)days in control group ( P>0.05). At 3 and 6 months after operation, the difference of Baumann angle between the normal and injured side was (3.2±0.8)°and (2.3±0.6)°in study group compared to (6.0±2.1)°and (5.8±1.3)°in control group (all P<0.01). According to the elbow function Flynn score at the last follow-up, the results were excellent in 44 children, good in 5 and fair in 1, with the excellent and good rate of 98.0% (49/50) in study group, and were excellent in 47 children, good in 5 and fair in 4, with the excellent and good rate of 92.9% (52/56) in control group ( P>0.05). There were no following complications in both groups, such as osteomyelitis, poor fracture healing, compartment syndrome, iatrogenic neurovascular injury or myositis ossificans. Conclusions:Both "de-sharpening" intramedullary elastic reduction with Kirschner wire and traditional three-dimensional manipulation for the treatment of Gartland type III posterolaterally-displaced supracondylar humerus fracture in children can achieve elbow joint function recovery, with low incidence of complications. However, the former avoids repeated manual reduction, with shorter operation time, less frequency of intraoperative fluoroscopy and better correction of the coronal plane deformity and rotation deformity.

Methods: The clinical data of patients with diagnosis of benign or pre-malignant pancreatic head tumor were retrospectively collected and analyzed,all of them underwent laparoscopic or robotic DPPHR between October 2015 and September 2021 at Division of Gastrointestinal and Pancreatic surgery,Zhejiang Provincial People's Hospital. Thirty-three patients were enrolled with 10 males and 23 females. The age(M(IQR)) was 54(32) years old(range: 11 to 77 years old) and the body mass index was 21.9(2.9)kg/m2(range: 18.1 to 30.1 kg/m2). The presenting symptoms included abdominal pain(n=12), Whipple triad(n=2), and asymptomatic(n=19). There were 7 patients with hypertension and 1 patient with diabetes mellitus. There were 19 patients who were diagnosed as American Society of Anesthesiologists class Ⅰ and 14 patients who were diagnosed as class Ⅱ. The student t test,U test, χ2 test or Fisher exact test was used to compare continuous data or categorized data,respectively. All the perioperative data and metabolic morbidity were analyzed and experiences on minimally invasive DPPHR were concluded. Results: Fourteen patients underwent laparoscopic DPPHR,while the rest of 19 patients received robotic DPPHR. Indocyanine green fluorescence imaging was used in 19 patients to guide operation. Five patients were performed pancreatico-gastrostomy and the rest 28 patients underwent pancreaticojejunostomy. Pathological outcomes confirmed 9 solid pseudo-papillary neoplasms, 9 intraductal papillary mucinous neoplasms, 7 serous cystic neoplasms, 6 pancreatic neuroendocrine tumors, 1 mucous cystic neoplasm, 1 chronic pancreatitis. The operative time was (309.4±50.3) minutes(range:180 to 420 minutes),and the blood loss was (97.9±48.3)ml(range:20 to 200 ml). Eighteen patients suffered from postoperative complications,including 3 patients experienced severe complications(Clavien-Dindo Grade ≥Ⅲ). Pancreatic fistula occurred in 16 patients,including 8 patients with biochemical leak,7 patients with grade B pancreatic fistula and 1 patient with grade C pancreatic fistula. No one suffered from the duodenal necrosis and none perioperative death was occurred. The length of hospital stay was 14(7) days (range:6 to 87 days). The follow-up was 22.6(24.5)months(range:2 to 74 months). None suffered from recurrence or metastasis. During the follow-up,all the patients were free of refractory cholangitis. Moreover,in the term of endocrine dysfunction,no postoperative new onset of diabetes mellitus were observed in the long-term follow-up. However,in the view of exocrine insufficiency,pancreatic exocrine insufficiency and non-alcoholic fatty liver disease (NAFLD) was complicated in 2 and 1 patient,respectively,with the supplement of pancreatic enzyme,steatorrhea and weight loss relieved,but NAFLD was awaited to be seen. Conclusions: Minimally invasive DPPHR is feasible and safe for benign or pre-malignant lesions of pancreatic head. Moreover,it is oncological equivalent to pancreaticoduodenectomy with preservation of metabolic function without refractory cholangitis.

The expression of cortactin in colorectal cancer and its relationship with clinicopathological and prognostic parameters / 中华肿瘤杂志

Objective: To investigate the expression of cortactin in colorectal cancer and its correlation with clinicopathological parameters and prognosis. Methods: The expressions of cortactin in normal colorectal mucosal tissue and colorectal cancer tissue in paraffin-embedded tissue microarray from 319 patients who were diagnosed as colorectal cancer and treated in Cancer Hospital of Chinese Academy of Medical Sciences from 2006 to 2009 was detected by immunohistochemistry. Kaplan-Meier method and Log rank test were used for survival analysis, and Cox proportional risk regression model was used for multivariate analysis. Results: The positive expression rates of cortactin in colorectal cancer tissue and normal colorectal mucosal tissue were 61.1% (195/319) and 5.6% (18/319, P<0.001), respectively. T-stage, N-stage, American Joint Committee on Cancer (AJCC) stage, degree of tumor differentiation, neural invasion and preoperative carcinoembryonic antigen (CEA) levels were associated with the expression of cortactin (P<0.05). The positive expression of cortactin was associated with poorer disease-free survival (P=0.036) and overall survival (P=0.043), and the effect was more significant in patients with stage Ⅱ to Ⅲ. For patients with stage Ⅱ-Ⅲ colorectal cancer, postoperative adjuvant therapy was associated with disease-free survival (P=0.007) and overall survival (P=0.015). The vascular tumor embolus, pathological type, preoperative CEA level and cortactin expression were independent influencing factors for disease-free survival (P<0.05). The age, AJCC stage, preoperative CEA level and cortactin expression were independent influencing factors for overall survival (P<0.05). Preoperative CEA level and cortactin expression were independent influencing factors for disease-free survival and overall survival (P<0.05). Conclusion: Cortactin is expressed in colorectal cancer and in stage Ⅱ-Ⅲ patients, it is a potential predictor of colorectal cancer prognosis.

Application and prospect of cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy in the treatment of peritoneal metastasis from colorectal cancer / 中华肿瘤杂志

Colorectal cancer is one of the common malignant tumors in China, and its incidence is increasing with years. As the second most common metastatic site of colorectal cancer, peritoneum is difficult to diagnose early and with a poor prognosis. Systemic intravenous chemotherapy was used as the main treatment strategy for peritoneal metastasis in the past, but its systemic toxic and side effects were obvious, and it could not effectively control tumor progression. In recent years, the continuous development of surgical techniques, concepts, and equipment, as well as the introduction of new chemotherapy drugs and targeted drugs have significantly improved the quality of life and prognosis of patients with peritoneal metastasis of colorectal cancer. Cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) can effectively eradicated the intraperitoneal free cancer cells and subclinical lesions, while reducing systemic side effects of chemotherapy drugs, and achieve the radical cure of the tumor at the macro and micro levels to the greatest extent. It has been used as the first-line treatment program for peritoneal metastasis of colorectal cancer at home and abroad. This article focuses on the analysis and summary of the survival efficacy, prognostic factor analysis, and chemotherapy safety of CRS+ HIPEC in the treatment of colorectal cancer peritoneal metastasis. The existing problems and controversies of HIPEC therapy are discussed simultaneously.

Gene mutation analysis of a family with familial generalized lentiginosis / 中华皮肤科杂志

Objective:To analyze clinical and genetic characteristics of a family with familial generalized lentiginosis, and to identify the causative gene mutation.Methods:Clinical characteristics and inherited pattern were analyzed in a family with familial generalized lentiginosis. Peripheral blood samples were obtained from the proband, his affected father and healthy mother, and genomic DNA was extracted. PCR was performed to amplify all exons and their flanking sequences of the SASH1 gene, followed by DNA sequencing. The proband′s mother and 100 unrelated healthy controls served as controls to determine the mutation site. Previous literature and gene mutation databases were searched to rule out the possibility that the SASH1 gene mutations were single nucleotide polymorphisms, and to determine whether it was a known mutation.Results:A 4-generation family consisting of 17 members was investigated, and there were 9 patients in the family, including 7 males and 2 females. Patients existed in each generation, and the disease was inherited in an autosomal dominant manner in this family. Gene sequencing revealed a heterozygous duplication mutation c.49_54dupCCCGAG in exon 1 of the SASH1 gene in the proband and his father. This mutation was not found in his mother or healthy controls, and had not been reported in previous literature or gene mutation databases.Conclusion:The heterozygous duplication mutation c.49_54dupCCCGAG in the SASH1 gene is a pathogenic mutation for the clinical manifestations of familial generalized lentiginosis in this family.

Clinical features of 24 cases of scleroderma-like cutaneous graft-versus-host disease / 中华皮肤科杂志

Objective:To investigate clinical features of and risk factors for scleroderma-like cutaneous graft-versus-host disease (GVHD) after allogeneic hematopoietic stem cell transplantation.Methods:Clinical data were collected from 24 patients with scleroderma-like cutaneous GVHD in Department of Dermatology, Peking University People′s Hospital from 2014 to 2019. Clinical features, treatment, prognosis, and possible factors influencing the development of scleroderma-like cutaneous GVHD were analyzed retrospectively.Results:Among the 24 patients, 11 were males, and 13 were females, aged 33 ± 12 years; 20 were human leukocyte antigen (HLA) -identical recipients, 4 were HLA-haploidentical recipients; GVHD occurred 18.5 (8.0, 30.9) months after transplantation. Nineteen patients had discontinued anti-rejection therapy or received low-dose anti-rejection drugs before the onset of GVHD. Fifteen patients presented with generalized scleroderma-like lesions, 1 with linear scleroderma-like lesions, 5 with morphea-like lesions, and 3 with fasciitis-like lesions. None of the 15 patients with generalized scleroderma-like GVHD had Raynaud syndrome. Thirteen patients were accompanied by graft rejection in other systems, 8 had joint mobility limitations, and 1 developed cutaneous squamous cell carcinoma secondary to chronic skin ulcers. All patients were treated with systemic glucocorticoids and immunosuppressive agents, and 11 also with topical glucocorticoids. An intensive follow-up was carried out in 11 patients, of whom 3 achieved marked improvement, 4 achieved improvement, 2 experienced exacerbation, and 2 died. A total of 223 patients with non-sclerodermatous cutaneous GVHD admitting during the same period served as controls, and the proportion of HLA-identical patients was significantly higher in the scleroderma-like cutaneous GVHD group (20/24, 83.3%) than in the non-sclerodermatous cutaneous GVHD group (47/223, 21.1%; P < 0.001) . Conclusions:Scleroderma-like cutaneous GVHD commonly occurs late, and can mimic clinical manifestations of all 4 types of spontaneous scleroderma. HLA-identical transplants, premature discontinuation or excessive dose reduction of anti-rejection drugs may be risk factors for scleroderma-like cutaneous GVHD.

Mechanism of Chemotherapy Resistance of Hepatocellular Carcinoma and Intervention with Chinese Medicine： A Review / 中国实验方剂学杂志

Multidrug resistance （MDR） has been a main culprit behind the failure of chemotherapy in patients with malignant tumors and a major obstacle to improving the life quality and prolonging the survival of patients. Hepatocellular carcinoma cells， the innate drug-resistant cells， are generally insensitive to radiotherapy and chemotherapy. Moreover， as the early symptoms of hepatocellular carcinoma are atypical， most patients are diagnosed at the advanced stage， with short survival period and high recurrence rate. Thus， the sensitivity to chemotherapy drugs is decreased. This explains how MDR becomes one of the important reasons for the failure of primary hepatocellular carcinoma （PHC） treatment. Therefore， it is an urgent task to search for safe and effective chemosensitizers with little adverse effect in the research on the drug resistance of hepatocellular carcinoma. As Chinese medicine has been widely applied in the treatment of tumors， the mechanisms of compound Chinese medicine prescriptions， Chinese medicine injections， and single Chinese medicinal in reversing chemotherapy resistance in liver cancer have attracted the interest of scholars. According to previous reports， the mechanisms can be summarized as increasing intracellular drug concentration， influencing changes in enzyme activity， inducing apoptosis， reversing abnormalities in cellular signaling pathways， and regulating the tumor microenvironment. Traditional Chinese medicine reduces the chemotherapy resistance of hepatocellular carcinoma cells through multiple targets and multiple pathways， thereby improving the chemotherapy sensitivity of the cancer cells and enhancing the toxicity of chemotherapeutic drugs to hepatocellular carcinoma cells. Therefore， exploring the mechanism of MDR of hepatocellular carcinoma from the perspective of traditional Chinese medicine is important for reversing the MDR and is of great reference value for clinical treatment of hepatocellular carcinoma. However， there are few experimental types and adverse effects available. Thus， the multi-mechanism and multi-target experiments and clinical research should be carried out in the future.

Chemical Compositions and Anti-tumor Effect of Tetrastigma hemsleyanum： A Review / 中国实验方剂学杂志

Due to the infinite proliferation， strong migration and loss of contact inhibition of tumor cells， tumor has become the most intractable diseases to be cured in the world. At present， the main treatments of tumor diseases are surgical resection， radiotherapy， chemotherapy， targeted-therapy and immunotherapy. Although these measures can inhibit or kill the tumor to a certain extent， they still cannot avoid adverse reactions and drug resistance. After thousands of years of clinical practice， traditional Chinese medicine （TCM） has the characteristics of good curative effect， few adverse reactions and significantly improving the quality of life in patients， which provides new ideas for the prevention and treatment of tumors. As an endemic and rare plant in China， Tetrastigma hemsleyanum has been listed in the 2015 edition of Zhejiang Provincial Processing Specification of TCM with the effects of heat-clearing and detoxification， detumescence and analgesia， dissipating phlegm and resolving masses. It has been reported that the chemical constituents of T. hemsleyanum are mainly flavonoids， polysaccharides， phenolic acids， terpenoids， steroids， volatile oils， alkaloids and so on. It can exert a broad spectrum of anti-tumor effects through various ways such as inhibiting proliferation， migration and invasion of tumor cells， inducing apoptosis of tumor cells， inhibiting angiogenesis of tumor cells， reversing multidrug resistance of tumor cells and regulating body autoimmunity. On the basis of reviewing relevant literature at home and abroad， this paper intends to systematically sort out the chemical and anti-tumor research of T. hemsleyanum， and in order to provide a new idea for its synergistic anti-tumor effect of multi-component， multi-pathway and multi-target， and finally provide theoretical basis for the research and development and clinical application of new anti-tumor drugs of T. hemsleyanum.
