PURPOSE: Follistatin-like protein 1 (FSTL1) is a secreted glycoprotein that has been shown to play a role in various types of cancer. However, the clinical significance and function of FSTL1 in breast cancer have not been reported. We investigated the role of FSTL1 in breast cancer in this study. METHODS: Enzyme-linked immunosorbent assays, western blot analysis, and reverse transcription polymerase chain reaction were used to monitor the expression of FSTL1 in breast cancer tissue and in serum samples from breast cancer patients. We employed a 4T1 breast cancer model and Fstl1(+/−) mice for in vivo studies. Hematoxylin and eosin staining, western blot analysis, and RNA sequencing were used to analyze the effect of FSTL1 on primary tumor growth and lung metastasis. RESULTS: We demonstrated that the expression of FSTL1 is reduced in both the breast cancer tissue and the serum of breast cancer patients. We showed that reduced levels of FSTL1 in serum correlate with elevated expression of Ki-67 and epidermal growth factor receptor (EGFR) in cancer tissues. Moreover, lowered expression of FSTL1 was associated with decreased survival in breast cancer patients. Experiments on the Fstl1(+/−) mouse model established that FSTL1 deficiency had no effect on primary tumor growth, but increased the lung metastases of breast cancer cells, resulting in reduced survival of tumor-bearing mice. RNA sequencing found significantly reduced expression of Egln3 and increased expression of EGFR in Fstl1(+/−) mice. Thus, our results suggest that FSTL1 may affect the expression of EGFR through Egln3, inhibiting the proliferation of breast cancer cells at lung metastatic sites. CONCLUSION: In conclusion, we suggest a suppressor role of FSTL1 in breast cancer lung metastasis. Furthermore, FSTL1 may represent a potential prognostic biomarker and a candidate therapeutic target in breast cancer patients.

Objective:To investigate the application value of mesocolon approach in transanal total mesorectal excision (TaTME).Methods:The retrospective cohort study was conducted. The clinicopathological data of 61 patients with middle or low rectal cancer who were admitted to the Nanchong Central Hospital of North Sichuan Medical College from January to December in 2018 were collected. There were 41 males and 20 females, aged from 43 to 81 years, with an average age of 62 years. Of the 61 patients, 30 patients undergoing TaTME with the conventional approach were allocated into traditional approach group, and 31 patients undergoing TaTME with mesocolon approach were allocated into mesocolon approach group. Observation indicators: (1) surgical situations; (2) postoperative recovery; (3) follow-up. Follow-up was conducted by outpatient examination and telephone interview once every 3 months to detect local recurrence and metastasis of tumors in patients up to June 2019. Measurement data with normal distribution were expressed as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were expressed as M (range), and comparison between groups was conducted using the Mann-Whitney U test. Count data were expressed as absolute numbers or percentages, and comparison between groups were analyzed using the chi-square test or Fisher exact probability. Comparison of ordinal data between groups was analyzed using the Mann-Whitney U test. Results:(1) Surgical situations: patients in the two groups underwent TaTME successfully, without conversion to laparotomy. The transabdominal operation time, volume of intraoperative blood loss, length of distal margin from surgical specimen, length of proximal margin from surgical specimen, cases with complete mesentery or with nearly complete mesentery ( the integrity of mesentery ), positive rate of circumferential margin, positive rate of distal margin, and the number of lymph node dissected of the traditional approach group were (126±56)minutes, 41.0 mL (range, 17.5-71.4 mL), 1.3 cm (range, 0.8-2.0 cm), (10.0±5.0)cm, 10, 20, 3.3%(1/30), 0, 13.7 (range, 9.0-17.0), respectively, versus (101±30)minutes, 44.0 mL (range, 25.0-67.5 mL), 1.6 cm (range, 1.1-2.2 cm), (12.0±3.0)cm, 23, 8, 6.5%(2/31), 0, 13.0 (range, 10.9-17.3) of the mesocolon approach group. There were significant differences in the transabdominal operation time, length of proximal margin from surgical specimen, and the integrity of mesentery between the two groups ( t=2.133, -2.286, χ2=10.250, P<0.05). There was no significant difference in the volume of intraoperative blood loss, length of distal margin from surgical specimen, or the number of lymph node dissected between the two groups ( Z=-0.662, -1.107, 0.304, P>0.05). There was also no significant difference in the positive rate of circumferential margin or positive rate of distal margin between the two groups ( P>0.05). (2) Postoperative recovery: the time to first anal flatus of the traditional approach group was 51 hours (range, 48-64 hours). There were 3 patients with complications in the traditional approach group. One patient in the traditional approach group had postoperative anastomotic fistula of Clavien-Dindo classification Ⅱ, and was cured after conservative treatment including sufficient drainage, parenteral nutrition and anti-infective treatment. One patient had chylous fistula of Clavien-Dindo classification Ⅱ, and was cured after conservative treatment. One patient had pulmonary infection of Clavien-Dindo classification Ⅳa, and was cured after treatment in ICU. The duration of postoperative hospital stay of the traditional approach group was (11.3±4.5)days. The time to first anal flatus of the mesocolon approach group was 59 hours (range, 49-70 hours). One patient in the mesocolon approach group had paralytic ileus of Clavien-Dindo classification Ⅰ, and was cured after conservative treatment. The duration of postoperative hospital stay of the mesocolon approach group was (9.6±1.8)days. There was no significant difference in the time to first anal flatus or duration of postoperative hospital stay between the two groups ( Z=-0.554, t=1.884, P>0.05). There was no significant difference in the complications between the two groups ( P>0.05). (3) Follow-up: 61 patients were followed up for 6-18 months, with a median time of 12 months. There was no local recurrence or metastasis of tumors in patients during the follow-up. Conclusion:The mesocolon approach is safe and feasible in TaTME, which abides by the principle of radical resection, and can decrease the difficulty of mesocolon excision, shorten the time of transabdominal operation, increase the length of proximal margin from tumor specimen, improve the integrity of mesentery.

Objective To investigate the safety and short-term efficacy of π-shaped anastomosis and circular anastomosis(reverse puncture device)in reconstruction of esophagojejunostomy after laparoscopic total gastrectomy.Methods A retrospective study was used to collect the clinical and pathological data of 75 cases of gastric cancer from January 2019 to March 2021.According to the different reconstruction methods of esophagojejunal anastomosis,the patients were divided into a linear cutting obturator group(π-shaped anastomosis group,n = 27)and a circular anastomat anastomosis group(reverse puncture device group,n = 48).The general information of the two groups,operation time,esophagojejunostomy time,intraoperative bleeding volume,number of intraoperative lymph node dissection,intraoperative complications,and postoperative complications were compared and analyzed.Results The operation time and esophagojejunostomy time in the π-shaped anastomosis group were(221.5±8.8)and(34.7±3.7)min,and the reverse puncture device group were and(246.9±5.6)and(47.2±4.6)min,respectively,the differences were statistically significant(t = 15.19,t = 11.81,P＜0.05).There were no statistical significance in the comparison of intraoperative bleeding volume and number of intraoperative lymph node dissection between the two groups(P＞0.05).In the reverse puncture device group,there were two intraoperative complications,including one case of esophageal jejunal anastomosis atresia and one case of anastomosis tear,postoperative complications occurred in 3 cases,postoperative anastomotic stenosis occurred in 2 case,and anastomotic bleeding occurred in 1 case.Conclusion Laparoscopic total esophagojejunostomy with π-shaped anastomosis and reverse puncture device are safe and feasible.In terms of esophagojejunostomy time,π-shaped anastomosis reconstruction time is shorter.When the small intestine diameter is relatively small and it is difficult to extend into the 25 mm stapler,the advantage of π-shaped anastomosis is more obvious.When the tumor is Siewert type Ⅰ and type Ⅱ adenocarcinoma of gastroesophageal junction,which infiltrates into above the dentate line,reverse puncture device method is recommended for reconstruction.

Objective: To observe the effect of medical instant hemostasis gauze combined with filament speed instant gauze on the drainage and flap healing after modified radical mastectomy. Methods: From August 2015 to August 2016, a total of 80 patients with modified radical mastectomy for breast cancer admitted to Huanxing Tumor Hospital, Chaoyang District, Beijing were selected.According to the random number table method, 80 patients who were ready for modified radical mastectomy for breast cancer were randomly divided into study group (40 cases) and control group (40 cases). Two kinds of hemostatic materials (medical hemolytic hemostatic gauze combined with fibril quick hemostatic gauze) were applied to the surgical wounds in the study group during the operation, while no medical hemostatic materials were used in the control group during the operation, and the other treatment was the same as that in the study group.Total drainage volume and drainage tube removal time were compared between the two groups 1 to 5 days after operation. Results: There were no statistically significant differences in the age, body mass index, and effusion production between the two groups (all P>0.05). The total drainage volume of the study group was (289.23±5.36) ml, and the total drainage volume of the control group was (492.15±8.56) ml.The difference between the two groups was statistically significant (t=8.543, P<0.05). The drainage time of the study group was (6.24±1.23) days, and the extraction time of the control group was (10.12±2.21) days.The difference between the two groups was statistically significant (t=6.203, P<0.05). Conclusion In addition to hemostatic function, using absorbable hemostatic gauze combined with surgicel fibrillar during the surgical process can significantly reduce postoperative subcutaneous fluid accumulation.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.
