ObjectiveTo assess the outcomes of laparoscopy-assisted surgery for treatment of advanced gastric cancer.MethodsA total of 115 patients with advanced gastric cancer were included between January 2014 and December 2018 were analyzed retroprospectively, the patients were divided into two groups: open surgery group (OS group, n=63) and laparoscopy-assisted surgery group (LAS group, n=52). Baseline characteristics, intraoperative parameters and postoperative items, and long-term efficacy were compared between the two groups.ResultsThere was no significant difference in preoperative baseline data including gender, age and preoperative serum parameters between the two groups (P>0.05). Intraoperative blood loss in the LAS group was significantly less than that in the OS group (P<0.05). In addition, the first feeding time after operation and postoperative hospital stay in the LAS group were significantly shorter than the OS group (P<0.05). Furthermore, numbers of white blood cells and neutrophils in the LAS group were fewer than that in the OS group at postoperative 2 days (P<0.05); the level of serum albumin in the LAS group was higher than that OS group (P<0.05). The number of lymph nodes detected during operation in the LAS group was more than that in the OS group (P<0.05). Operative time and occurrence of postoperative complications were not statistically significant between the two groups (P>0.05). One hundred and ten of 115 patients were followed- up, the follow-up rate was 95.7%. The follow-up time ranged from 6 to 48 months, with a median follow-up time of 12.4 months. The disease-free survival time of the OS group was 12.2±6.5 months, while that of the LAS group was 13.5±7.4 months. There was no significant difference between the two groups (P>0.05).ConclusionsLaparoscopic technique in treatment of advanced gastric cancer has the minimally invasive advantage, less intraoperative blood loss, less surgical trauma, and faster postoperative recovery in comparing to the traditional open surgery. Also the lymph node dissection is superior to open surgery. The curative effect is comparable to that of open surgery.
ObjectiveTo investigate the characteristics and prognostic value of cellular immune function in severe patients with coronavirus disease 2019 (COVID-19).MethodsA cohort study was conducted to collect the clinical data of 119 severe patients admitted to the Renmin Hospital of Wuhan University (Eastern District) including 60 males (50.4%) and 59 females (49.6%), with an average age of 60.9±14.2 years. The primary endpoint of follow-up was death in the hospital, and the disease outcome classification was the secondary endpoint of follow-up within 30 days after admission. We analyzed the correlation between cellular immune function and COVID-19 prognosis.Results A total of 22 patients died during this process, and 47 patients were severe/critical during the follow-up period. The counts of CD3+, CD4+, CD8+, and CD19+ in the primary endpoint events were significantly different between the survival group and the death group (all P<0.05). The counts of CD3+, CD4+, CD8+, CD19+ in the secondary endpoint events were significantly different between the normal group and the severe/critical group (all P<0.05). The results of the receiver operating characteristic (ROC) curve showed that the area under the cellular immune function curve of dead patients and severe/critical patients had good predictive value (all P<0.05).ConclusionCell immune function has good clinical and prognostic value for COVID-19.
ObjectiveTo summarize the clinical morphological classification feature of symptomatic spontaneous isolated celiac artery dissection (SICAD), basing on the relative diameter of the true lumen (TLRD) and type of lesion, and then summarize the reasonable clinical treatment strategies and timing of arterial reconstruction.MethodsRetrospectively analyzed the imaging data, treatment methods, perioperative complications, and follow-up results of 26 symptomatic SICAD patients admitted to the Department of Endovascular Surgery of The First Affiliated Hospital of Zhengzhou University from May 2012 to May 2019, patients were divided into conservative treatment group (n=12) and endovascular intervention group (n=14) according the treatment, and then compared the clinical data of the two groups.ResultsTwelve patients in the conservative treatment group had an average of 12.6 days (5–22 days) and discharged from hospital with better condition, of which 11 patients’ TLRD≥30%. In the endovascular intervention group, 2 patients continued to aggravate the symptoms at the 3rd day of admission and received endovascular intervention, the remaining 12 patients’ symptoms were not significantly relieved or the symptoms reappeared after averaged 11.4 days, whose TLRD<30% or diameter >1.5 cm. Compared with the endovascular intervention group, the duration of symptoms was shorter (P=0.04), proportions of back pain (P=0.02) and chest pain (P=0.04) were lower, TLRD value and proportion of TLRD value>30% (subtype of a) were higher (P=0.01, P=0.02). The average follow-up duration of 26 patients was 28.2 months (12–83 months). The follow-up results of all patients in the conservative treatment group were good and no relevant symptoms had appeared since discharge. One patient in the endovascular intervention group had transient liver function damage, 1 patient had severe deformation of the proximal end of the stent at 1 year after implantation of the celiac artery stent. The remaining patients were stable with no progress.ConclusionsFor symptomatic SICAD, if the clinical symptoms are stable after hospitalization, conservative medication and close imaging follow-up are preferred, if there is no relief of symptoms, continuous organ perfusion and other manifestations based on medication, endovascular intervention can be considered for arterial reconstruction, the early and medium follow-up results were satisfactory under this treatment algorithm. In addition, there are differences in TLRD value between the conservative treatment group and the endovascular intervention group, suggesting that TLRD as the morphological characteristics of the classification has a potential guiding significance for the development of clinical treatment strategy.
