RESUMO
Alpha-fetoprotein producing gastric cancer (AFPGC) is a special type of gastric cancer. AFPGC is considered to be the most highly invasive tumor with a high degree of malignancy and prone to metastasis. As a consequence, it usually causes unsatisfied treatment effect and the prognosis is poor. At present, treatment methods and monitoring indicators have limited effect on AFPGC. VEGF, HER2, AFP, GPC3 and SALL4 are cogently associated with tumor genesis and development. If we can reasonably guide the treatment and prognosis of AFPGC patients, it will greatly improve the situation of patients and improve the survival of patients. This article reviews the research progress of the genes related to the treatment and prognosis of AFPGC.
RESUMO
Objective:To investigate the application value of Clavien-Dindo classification in evaluation of postoperative short-term complications of Da Vinci robotic-assisted or laparoscopic-assisted total gastrectomy with D 2 lymphadenectomy. Methods:The retrospective cohort study was conducted. The clinicopathological data of 262 patients with gastric cancer who were admitted to the 940th Hospital of Joint Logistic Support Force of Chinese People′s Liberation Army from January 2016 to January 2019 were collected. There were 214 males and 48 females, aged (58±11) years, with a range from 17 to 81 years. Of 262 patients, 120 cases undergoing Da Vinci robotic-assisted total gastrectomy + D 2 lymphadenectomy + Roux-en-Y anastomosis were divided into robotic group, and 142 cases undergoing laparoscopic-assisted total gastrectomy + D 2 lymphadenectomy + Roux-en-Y anastomosis were divided into laparoscopic group. Observation indicators: (1) intraoperative and postoperative situations; (2) postoperative pathological examination; (3)complications; (4) stratified analysis; (5) follow-up. Follow-up using outpatient examination and telephone interview was performed to detect complications, tumor recurrence and survival of patients within postoperative 2 months. The follow-up was up to May 2019. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed using the t test. Measurement data with skewed distribution were represented as M (range), and comparison between groups was analyzed using the Mann-Whitney U test. Count data were described as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test or Fisher exact probability. Comparison of ranked data between groups was analyzed using the rank sum test. Results:(1) Intraoperative and postoperative situations: cases undergoing conversion to open surgery, the operation time, volume of intraoperative blood loss, the number of lymph node dissected, time to first flatus, time to initial fluid diet intake, duration of postoperative hospital stay of the robotic group were 1, (243±42)minutes, 100 mL(range, 100-150 mL), 38±15, (2.8±1.0)days, 3 days(range, 3-4 days), 11 days(range, 9-13 days), respectively.

Conclusions:The Clavien-Dindo classification can be used in evaluating postoperative short-term complications of Da Vinci robotic-assisted or laparoscopic-assisted total gastrectomy with D 2 lymphadenectomy. Compared with laparoscopic-assisted total gastrectomy with D 2 lymphadenectomy, Da Vinci robotic-assisted total gastrectomy with D 2 lymphadenectomy has the advantages of minimally invasiveness, low incidence of overall and severe complication.
RESUMO
Objective To explore the safety and feasibility of robot splenectomy.Methods 65 patients undergoing robotic or laparoscopic splenectomy at No.940 Hospital of Chinese people's Liberation Army Joint Service Support Force from Jan 2015 to Sep 2019 were analyzed retrospectively.Results The operation time and total hospitalization cost of robot spleen resection group and laparoscopic splenectomy group were [(167 ± 34) min vs.(123 ± 24) min,t =8.554,P =0.00] and (73 002 ± 21 009) yuan vs.(42 095 ± 9 999) yuan,(t =6.484,P =0.00),respectively.In laparoscopy group,3 cases were converted to laparotomy.In the subgroup of splenic hilum thickness ≥ 5 cm,the intraoperative bleeding volume of robot group and laparoscopic group was (145 ± 67) ml vs.(263 ± 180) ml,(t =-2.195,P =0.04).There were significant differences in VAS score (3 ±1) vs.(4 ±1),(t=2.175,P=0.04).Conclusion Robotic splenectomy is safe and feasible.For patients with splenomegaly,robot surgery has more minimally invasive advantages than laparoscopy,but it is expensive and time-consuming.
RESUMO
@#Atherosclerosis(AS), characterized with the accumulation of lipids on the vessel wall, is an immune-related inflammatory disease which promotes the progression of cardiovascular diseases(CVD). The imbalance of Treg/Th17 accelerates the progression of AS. Yangyin Huoxue Prescription(YHF)is an efficient traditional Chinese medicine used in the treatment of AS, but the effects of YHF on the balance of immunity have still not been clarified. This project was designed to investigate the effects of YHF on the imbalance of Treg/Th17 and AS in ApoE-/- mice induced by high-fat diet(HFD). ApoE-/- mice were given HFD to induce AS and administered low-dose YHF(18 g/kg)or high-dose YHF(36 g/kg)for 20 weeks. Atherosclerotic plaque area was analyzed by oil red O staining. Serum lipids were measured by biochemical kits. Treg or Th17 cells in peripheral blood were detected by flow cytometry. mRNA and protein expression of Foxp3 and RORγt of aortas were determined by qRT-PCR, Western blot and immunohistochemistry. Splenic CD4+T cells of mice were isolated and activated by anti-CD3/CD28, and then treated with lipopolysaccharide(LPS)and YHF. The expression of mRNA and protein of Foxp3 and RORγt were detected by qRT-PCR and immunofluorescence. It was found that YHF reduced the plaque area, decreased lipid level and increased the ratio of Treg cells in peripheral blood. Moreover, YHF increased mRNA or protein expression of Foxp3 in aortas in vivo or CD4+T cells in vitro while decreasing mRNA or protein expression of RORγt. These results suggested that YHF can regulate the imbalance of Treg/Th17 in ApoE-/- mice induced by HFD, and reduce the inflammatory stimulation of LPS on CD4+T cells, thereby improving AS.
RESUMO
Objective To compare the short-term clinical effects of Da Vinci robotic surgical systemassisted and laparoscopy-assisted operations for gastrointestinal stromal tumor (GIST).Methods The retrospective cohort study was conducted.The clinical data of 98 patients with GIST who were admitted to the Lanzhou General Hospital of Chinese People's Liberation Army from June 2016 to May 2018 were collected.Of 98 patients,45 undergoing Da Vinci robotic surgical system-assisted surgery for GIST and 53 undergoing laparoscopy-assisted surgery for GIST were respectively allocated into the robotic group and laparoscopic group.The associate senior and above doctors performed the surgery.The wedge resection was applied to patients with diameter of gastric stromal tumor < 5 cm,and subtotal gastrectomy + digestive tract reconstruction (gastrojejunostomy and Brauns anastomosis) were applied to patients with diameter of gastric stromal tumor > 5 cm or tumor located in the cardia and pylorus.Patients with intestinal stromal tumor underwent intestinal resection + end-to-side anastomosis.Observation indicators:(1) surgical and postoperative situations;(2) follow-up.Follow-up using outpatient examination and telephone interview was performed to detect tumor recurrence or metastasis up to July 2018.Measurement data with normal distribution were represented as x-±s,and comparison between groups was done using the independent-sample t test.Measurement data with skewed distribution were represented as M (range),and comparison between groups was done using nonparametric test.Comparisons of count data were analyzed using chi-square test.Results (1) Surgical and postoperative situations:98 patients underwent successful surgery.The operation time,volume of intraoperative blood loss,recovery time of gastrointestinal function,time of gastrointestinal decompression tube removal,time of abdominal drainage tube removal and duration of postoperative hospital stay were respectively (152± 49) minutes,100 mL (range,10-300 mL),(2.6 ± 0.6) days,(1.1 ± 0.3)days,(5.7±1.2)days,(8.3±1.3)days in the robotic group and (201±62)minutes,100 mL (range,5-600 mL),(3.1±0.7) days,(2.1 ± 1.5) days,(6.9 ± 3.4) days,(11.6 ± 7.0) days in the laparoscopic group,with statistically significant difference between groups (t =-3.983,Z =2.104,t =-3.776,-3.637,-2.018,-2.817,P<0.05).(2) Follow-up:98 patients were followed up for 2-24 months,with a median time of 13 months.During the follow-up,there was no tumor recurrence or metastasis between groups.Conclusion Compared with laparoscopy-assisted surgery,Da Vinci robotic surgical system-assisted surgery for GIST is safe and feasible,with advantages of shorter operation time,faster postoperative recovery and shorter duration of hospital stay.

RESUMO
In order to examine the strong anticancer action and low toxicity of Trichostatin A (TSA), the effect of TSA was examined on the growth inhibition, acetylation of histone H3 and apoptosis in HL-60 cells by employing MTT, immunocytochemical techniques, and Annexin-V-FITC/ PI assay. Our results showed that TSA could inhibit proliferation of HL- 60 cells in a time- and dose-dependent manner, and the IC50 at the 36th h was 100 ng/ml. The apoptosis-inducing effect of TSA on HL-60 cells was also time- and dose-dependent. But it didn't demonstrate apparent apoptosis induction in NPBMNCs within specific dose and time range. Both of the acetylation of histone H3 in HL-60 cells and NPBMNCs increased significantly (P<0.05) after treated with 100 ng/ml TSA for 4 h. However, there was no significant differences between the two groups (P>0.05). It is concluded that TSA can inhibit growth and induce apoptosis of HL-60 cells in a time- and dose-dependent manner, and is able to selectively induce apoptosis in HL-60 cells but does not respond in NPBMNCs under the same conditions. The difference of TSA between HL-60 cells and NPBMNCs can't be explained by the regulation of histone acetylation.
