Objective To investigate the efficacy and safety of the Corheart 6 left ventricular assist system in patients with end-stage heart failure. Methods A retrospective study was conducted on patients with end-stage heart failure who were treated with Corheart 6 left ventricular assist system from March 2022 to June 2024 in 4 hospitals in Jiangsu Province. The efficacy of the device was evaluated by comparing changes in clinical indicators at preoperative, discharge, 3-month postoperative, and 6-month postoperative timepoints, including the New York Heart Association (NYHA) functional classification, left ventricular ejection fraction (LVEF), and left ventricular end-diastolic diameter (LVEDD). The safety of the device was assessed by analyzing the intraoperative position and orientation of the blood pump inlet cannula, as well as the incidence of adverse events. Results In this study, 39 patients were collected, including 34 males and 5 females with a mean age of (56.4±12.5) years, ranging from 20 to 75 years. There was no operative death. There was no death in postoperative 3 months with a survival rate of 100.0%. There were 3 deaths in 6 months postoperatively, with a survival rate of 92.3%. All patients had a preoperative NYHA cardiac function classification of class Ⅳ. The NYHA cardiac function class of the patients improved (P<0.05) at discharge, 3 and 6 months after surgery when compared to the preoperative period. LVEF was significantly higher at 3 months after surgery than that during the preoperative period (P<0.05). LVEDD was significantly smaller at discharge, 3 and 6 months after surgery than that during the preoperative period (P<0.05). The safety evaluation's findings demonstrated that all 39 patients' intraoperative blood pump inlet tubes were oriented correctly, the artificial blood vessel suture sites were appropriate, there were no instances of device malfunction or pump thrombosis, or instances of bleeding or hemolysis, and the rate of the remaining adverse events was low. Conclusion With a low rate of adverse events and an excellent safety profile, the Corheart 6 left ventricular assist system can efficiently enhance cardiac function in patients with end-stage heart failure. It also has considerable clinical uses.

OBJECTIVE: To explore the clinical characteristics and prognostic factors of patients with extranasal NK/T-cell lymphoma (NKTCL). METHODS: The clinical data of 138 patients with NKTCL diagnosed in 10 medical centers of Huaihai Lymphoma Working Group from June 2015 to April 2021 were collected and analyzed retrospectively. The differences in clinicopathological characteristics of patients with different involvement and efficacy of pegaspargase regimen were compared, as well as perform survival analysis. RESULTS: A total of 138 extranasal NKTCL patients were included, with a median age of 46 years, and the ratio of males to females was approximately 2∶1. There were 39 patients with gastrointestinal involvement, 32 patients with oropharyngeal involvement, 17 patients with skin involvement, 11 patients with lymph node involvement, 11 patients with orbital involvement, and 28 patients with other parts involvement. Patients with skin involvement had a higher proportion of advanced disease and a lower proportion of CD56 positive rate compared to those with oropharyngeal involvement. Among the patients with gastrointestinal involvement, the survival rate of patients who received pegaspargase regimen was significantly higher than those who were treated without pegaspargase (P < 0.01). Multivariate analysis showed that serum creatinine was an independent prognostic factor for patients with skin involvement ( HR =1.027, 95%CI : 1.001-1.054, P =0.040), ECOG PS and EBV DNA were independent prognostic factors for patients with gastrointestinal involvement ( HR =2.635, 95%CI : 1.096-6.338, P =0.030; HR =4.772, 95% CI : 1.092-20.854, P =0.038), and ECOG PS and CA stage were independent prognostic factors for patients with oropharyngeal involvement ( HR =13.875, 95%CI : 2.517-76.496, P =0.002; HR =20.261, 95%CI : 2.466-166.470, P =0.005). CONCLUSION The clinicopathological characteristics of extranasal NKTCL patients with different sites of involvement are vary, and effective individualized treatment need to be further explored.

Objective To evaluate the acceptability and effectiveness of different doses of midazolam oral solution in sedating infants during echocardiographic studies.Methods Two hundred and fourty patients aged 1 to 3 years who underwent echocardiographic study in sedation in our hospital were enrolled in this study.After recording the baseline data of all infants,they were randomly divided into four groups:0.3 mg·kg-1 midazolam oral solution group(M1 group),0.5 mg·kg-1 midazolam oral solution group(M2 group),0.7 mg·kg-1 midazolam oral solution group(M3 group)and 0.5 mL·kg-1 10%chloral hydrate administrated rectally group(C group),60 case per group,and the sedation was performed in the corresponding method of each group.The 5-point facial hedonic and Ramsay scales were used to evaluate acceptability and effectiveness in sedation.The onset time and duration time of sedation were recorded.Results Compared with the C group,the 5-point facial hedonic scale scores in M1,M2,and M3 groups increased during sedation(F=17.50,P<0.017).The onset time of sedation in the M1 and M2 groups was longer than that in the C group(P<0.017),and the duration time of sedation in the M1 and M2 groups was shorter than that in the C group(P<0.017).There was no significant difference in the onset time(P=0.85)and duration time(P=0.50)of sedation between the M3 and C groups.The onset time of sedation in the M1and M2groups was longer than that in the M3 group(P<0.017),and the duration time of sedation in the M1 and M2 groups were shorter than that in the M3 group(P<0.017).Conclusions The acceptability of infants with midazolam oral solution sedation under echocardiographic study was better than that of 10%chloral hydrate administrated rectally.There were fewer adverse reactions with the midazolam oral solution.The 0.7 mg·kg-1 midazolam oral solution had a rapid onset of sedation and definite effect.

Objective:To introduce the application of highly selective arterial indocyanine green angiography (hereinafter referred to as highly selective arterial angiography) in the design of anterolateral thigh free flap.Methods:This study was a retrospective observational study. From November 2023 to April 2024, 29 patients with wounds in extremities which were repaired by anterolateral thigh free flaps designed under the assistance of highly selective arterial angiography and met the inclusion criteria were admitted to the Department of Hand Surgery and Department of Wound Repair Surgery of Suzhou Ruihua Orthopedic Hospital, including 26 males and 3 females, aged 16 to 71 years. The wound area after debridement ranged from 8.0 cm×4.5 cm to 27.0 cm×16.0 cm. During the surgery, highly selective arterial angiography was used to assist in flap design. The fluorescence development range of the source arteries or perforators of flaps was observed. The blood supply range of the source arteries or perforators of flaps was determined based on the fluorescence development of the skin, and the excision position of the flap was adjusted. The flap incision area ranged from 9.0 cm×6.0 cm to 29.0 cm×16.0 cm. During the surgery, the number of highly selective arterial angiography, the type of source artery of perforators for puncture, and changes in the excision position of flaps were observed and recorded. After surgery, the blood supply and survival of flaps, the healing of wounds and the survival of skin grafts in the flap donor sites, and the angiography-related complications were observed.Results:All the 32 flaps of 29 patients were successfully excised. The highly selective arterial angiography was performed 37 times, including 13 cases of puncture of the oblique branch of the lateral circumflex femoral artery, 6 cases of puncture of the descending branch, 8 cases of double puncture of the oblique and descending branches, and 2 cases of puncture of arteries from other branches. During the surgery, the excision position of 28 flaps did not change, the excision position of 3 flaps moved towards proximal extremity of the thigh, and the excision position of 1 flap moved towards distal extremity of the thigh. All the flaps survived successfully after the surgery, and there was no partial necrosis of the flaps at the proximal or distal ends. The wounds in the flap donor sites healed, and all skin grafts survived. No angiography-related complications occurred.Conclusions:Highly selective arterial angiography can be used to determine the blood supply range of the source artery and perforators of the anterolateral thigh free flaps during the surgery. It can evaluate the blood supply of flaps more intuitively and objectively. Its application in assisting flap design can avoid partial flap necrosis caused by unreasonable preoperative design to a certain extent, and it is safe and reliable.

Objective To explore the safety and feasibility of the application of day surgery management model under enhanced recovery after surgery(ERAS)concept in patients undergoing gynecologic laparoscopic surgery.Methods A non-randomized concurrent control trial was conducted on the patients who underwent laparoscopic surgery in our department from January to August 2021.A total of 92 patients admitted on odd date were assigned into Ward B of our department and served as the control group,and another 96 patients hospitalized on even date were subjected into Ward A and served as the observation group.The control group was given the routine treatment schedule,including the relevant examinations after admission and general operation procedure during hospitalization.The observation group was under a day surgery management model based on the concept of ERAS,with aid of a day surgery team and optimized perioperative management measures,including pre-hospital rehabilitation,shortening water fasting before surgery,multi-mode analgesia,preventive antiemesis,intraoperative warmth,prevention of deep vein thrombosis,immediate postoperative eating and activity,and follow-up after discharge.Postoperative subjective comfort,intestinal function recovery,social and economic benefits,postoperative complications and inflammatory indicators were compared between the 2 groups.Results In 0～6,7～12 and 13～24 h after operation,the scores of thirst,hunger,nausea,pain,abdominal distension and pharyngeal discomfort were significantly lower in the observation group than the control group(P＜0.01).The observation group had obviously shorter length of hospital stay and ealier bowel sound recovery and first anal exhaust than the control group(P＜0.01).No postoperative complication,such as fall,unplanned secondary operation or wound infection was observed in both groups.The postoperative inflammatory indicators,including procalcitonin(PCT),neutrophil percentage(Neu％)and white blood cell count(WBC)were all in the normal ranges in the 2 groups at 24 h and 3 and 7 d after surgery.Statistical differences were found in firstly postoperative mobilization,length of hospital stay,hospitalization cost and patient satisfaction between the 2 groups(P＜0.01).Conclusion ERAS-based day surgery management model has the advantages of shortening hospital stay,reducing medical costs,promoting postoperative rehabilitation,and improving the comfort and satisfaction in patients undergoing gynecologic laparoscopic surgery.

Constipation is a prevalent ailment which might significantly impact the quality of people's life and rise some associated deseases risks. In this study, a chronic constipation mouse model was established using loperamide hydrochloride. Mice were gavaged an Angelica sinensis Cistanche Fiber Compound, comprised of Dang Gui [Angelica sinensis (Oliv.) Diels], Rou Cong Rong (Cistanche deserticola Y.C.Ma), wheat fiber, and low-molecular-weight xylan at high dosage (3.6 g·kg^-1, 30 times the recommended human dose) and low dosage (0.6 g·kg^-1, 5 times the recommended human dose) for 14 days. The study assessed the therapeutic efficacy of the compound by observing fecal morphology, measuring water content, and conducting small intestine motility experiments. Furthermore, enzyme-linked immunosorbent assays (ELISA) were conducted to evaluate the serum levels of gastrointestinal hormones including motilin (MTL), gastrin (GAS), the inflammatory factors interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α). Histopathological examination with H&E staining was employed to evaluate colonic tissue damage. Additionally, Western blot and immunohistochemistry experiments were conducted to examine the expression levels of aquaporin-3 (AQP3) and c-Kit in the colon. The results indicated that the Angelica sinensis Cistanche Fiber Compound could improve fecal morphology, increase fecal water content, enhance small intestinal transit rates in mice. Additionally, there was a significant elevation in the serum levels of gastrointestinal hormones and a notable reduction in the levels of inflammatory factors. The improvement in colonic histopathological damage was accompanied by a marked decrease in the expression of the colonic water channel protein AQP3 and a significant increase in c-Kit expression. These results collectively suggested the presence of a dose-response relationship. These findings indicate that the Angelica sinensis Cistanche Fiber Compound effectively alleviates constipation in mice. Its action is associated with the regulation of colonic water channel protein AQP3 and c-Kit expression, along with the modulation of serum inflammatory factors and gastrointestinal hormones. This experiment was approved by the Animal Experiment Ethics Committee of Jinan University.
