ABSTRACT
Objective: To examine the clinical effect of minimally invasive duodenum preserving pancreatic head resection(DPPHR) for benign and pre-malignant lesions of pancreatic head. 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.

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.

To evaluate the clinical application of arthroscopy in the diagnosis and treatment of anterior impingement syndrome of the ankle joint in physical workers. A retrospective study was carried out at the Department of Orthopedics, the First Hospital affiliated to Nanhua University, Hengyang, China from March 2005 to December 2011. Seventeen cases of anterior impingement syndrome of the ankle joint were confirmed, and treated through arthroscopy. All these patients conformed to regular follow-up postoperatively, and clinical details, as well as postoperative prognosis were retrieved and analyzed retrospectively. The efficacy was evaluated by the American Orthopedic Foot and Ankle Society [AOFAS] hindfoot-ankle scoring system, and pain relief was assessed by visual analogue scoring [VAS]. Anterolateral impingement syndrome was found in 11 patients, anteromedial impingement syndrome in 4, while anterior impingement syndrome in 2 via arthroscopic examination. The VAS was reduced from 5.2-1.1, and the AOFAS score was elevated from 76.4-95.8 postoperatively; both of which demonstrated statistical differences when compared to preoperative scores. It was also found that concomitant cartilage damage was an indicator of poor prognosis in arthroscopic treatment of impingement syndrome of the ankle joint. Satisfactory results could be achieved for physical workers with anterior impingement syndrome treated by arthroscopy. As the cartilage damage is an indicator of poor prognosis, an early operation is advocated when the prognosis of anterior impingement syndrome is confirmed

OBJECTIVE@#To explore the effect of chronic iron overload on the lesion of atherosclerosis (AS) in apolipoprotein (apo) E knockout mice.@*METHODS@#Twenty-four ApoE knockout mice were randomly divided into ApoE knockout group (0.1 mL saline for 4 weeks) and iron overload group (10 mg iron dextran for 4 weeks). The levels of serum iron (SI), total iron binding capacity, contents of malondialdehyde (MDA), and activity of superoxide dismutase (SOD) in the liver were measured. Iron deposition in the liver and heart was determined, and atherosclerotic plaque areas of the sinus aortae were analyzed.@*RESULTS@#In the iron overload group, the levels of SI increased by 377.86%, the saturation of transferrin increased by 121.98% and the levels of iron in the liver increased by 2,548.15% (P<0.01). The contents of MDA in the liver increased by 32.51% (P<0.01), and the activity of SOD in the liver decreased by 17.2% in the ApoE knockout group (P<0.05). The level of MDA in the liver increased by 411.15%, and the activity of SOD in the liver decreased by 46.84% in the iron overload group (P<0.01). There was a significant deposition of iron in the liver and heart of mice, and the areas of atherosclerotic plaque of sinus aortae increased markedly in the iron overload group.@*CONCLUSION@#Chronic iron overload may promote the development of AS lesion in the ApoE knockout mice, in which the increased oxidative stress and lipid oxidation may involve.
