OBJECTIVE: To investigate the effect and relative mechanism of Recombinant Human Thrombopoietin (rhTPO) on long-term hematopoietic recovery in mice with acute radiation sickness. METHODS: Mice were intramuscularly injected with rhTPO (100 μg/kg) 2 hours after total body irradiation with ⁶⁰Co γ-rays (6.5 Gy). Moreover, six months after irradiation, peripheral blood, hematopoietic stem cells (HSC) ratio, competitive transplantation survival rate and chimerization rate, senescence rate of c-kit⁺ HSC, and p16 and p38 mRNA expression of c-kit⁺ HSC were detected. RESULTS: Six months after 6.5 Gy γ-ray irradiation, there were no differences in peripheral blood white blood cells, red blood cells, platelets, neutrophils and bone marrow nucleated cells in normal group, irradiated group and rhTPO group (P>0.05). The proportion of hematopoietic stem cells and multipotent progenitor cells in mice of irradiated group was significantly decreased after irradiation (P<0.05), but there was no significant changes in rhTPO group (P>0.05). The counts of CFU-MK and BFU-E in irradiated group were significantly lower than that in normal group, and rhTPO group was higher than that of the irradiated group(P<0.05). The 70 day survival rate of recipient mice in normal group and rhTPO group was 100%, and all mice died in irradiation group. The senescence positive rates of c-kit⁺ HSC in normal group, irradiation group and rhTPO group were 6.11%, 9.54% and 6.01%, respectively (P<0.01). Compared with the normal group, the p16 and p38 mRNA expression of c-kit⁺ HSC in the irradiated mice were significantly increased (P<0.01), and it was markedly decreased after rhTPO administration (P<0.01). CONCLUSION The hematopoietic function of mice is still decreased 6 months after 6.5 Gy γ-ray irradiation, suggesting that there may be long-term damage. High-dose administration of rhTPO in the treatment of acute radiation sickness can reduce the senescence of HSC through p38-p16 pathway and improve the long-term damage of hematopoietic function in mice with acute radiation sickness.

OBJECTIVE: To study the effect of interleukin-6 (IL-6) gene deletion on radiation-induced hematopoietic injury in mice and relative mechanism. METHODS: Before and after whole body ⁶⁰Co γ-ray irradiation, it was analyzed and compared that the difference of peripheral hemogram, bone marrow hematopoietic stem and progenitor cells conts in IL-6 gene knockout (IL-6^-/-) and wild-type (IL-6^+/+) mice and serum IL-6 and G-CSF expression levels in above- mentioned mouse were detected. Moreover, 30 days survival rate of IL-6^-/- and IL-6^+/+ mice after 8.0 Gy γ-ray irradiation were analyzed. RESULTS: IL-6 levels in serum of IL-6^+/+ and IL-6^-/- mice were respectively (98.95±3.85) pg/ml and (18.36±5.61) pg/ml, which showed a significant statistical differences (P<0.001). There were no significant differences of peripheral blood cell counts and G-CSF level in serum between IL-6^+/+ and IL-6^-/- mice before irradiation (P>0.05). However, the number of leukocytes, neutrophils, lymphocytes, monocytes, platelets in peripheral blood and G-CSF level in serum of IL-6^-/- mice were significantly decreased at 6 h after 8.0 Gy γ-ray irradiation compared with that of IL-6^+/+ mice. On days 30 after 8.0 Gy γ-ray irradiation, the survival rate of IL-6^+/+ and IL-6^-/- mice was 62.5% and 12.5%, and the mean survival time of dead mice was 16.0±1.0 and 10.6±5.3 days, respectively. On days 14 after 6.5 Gy γ-ray irradiation, bone marrow nucleated cells in IL-6^+/+ and IL-6^-/- mice were respectively (10.0±1.2)×10⁶ and (8.3±2.2)×10⁶ per femur. Compared with IL-6^+/+ mice, the proportion of Lin^-Sca-1^-c-kit⁺ (LK) in bone marrow of IL-6^-/- mice had no significant change (P>0.05), but the proportion of Lin^-Sca-1⁺c-kit⁺ (LSK) was significantly decreased (P<0.05). CONCLUSION IL-6 plays an obvious role in regulating hematopoietic radiation injury, and IL-6 deficiency can inhibit the radiation-induced increase of endogenous G-CSF level in serum, aggravates the damage of mouse hematopoietic stem cells（HSC） and the reduction of mature blood cells in peripheral blood caused by ionizing irradiation, resulting in the shortening of the survival time and significant decrease of the survival rate of mice exposed to lethal dose radiation.

OBJECTIVE: To confirm the therapeutic effect of recombinant human thrombopoietin (rhTPO) on rhesus monkeys irradiated with 5.0 Gy ⁶⁰Co γ-ray, and provide experimental basis for clinical treatment of similar patients. METHODS: Fourteen adult rhesus monkeys were irradiated with ⁶⁰Co γ-ray on both sides at the dose of 5.0 Gy (dose rate 69.2 cGy/min) to establish the acute radiation sickness model. The monkeys were divided into irradiation group (n=5), rhTPO 5 μg/kg group (n=4) and rhTPO 10 μg/kg group (n=5). Two hours after irradiation, the three groups of monkeys were injected with saline 0.1 ml/kg, rhTPO 5 μg/kg（0.1 ml/kg） and rhTPO 10 μg/kg(0.2 ml/kg), respectively. The general signs, survival, peripheral hemogram and serum biochemistry of rhesus monkeys were observed before and after irradiation, and the differences between rhTPO group and irradiation control group were compared. RESULTS: After total body irradiation with 5.0 Gy⁶⁰Co γ-ray, rhesus monkeys successively showed fever, hemorrhage, sharp decrease of whole blood cell counts in peripheral blood and disorder of serum biochemical indexes. Compared with the irradiated control group, a single intramuscular injection of rhTPO 5 μg/kg or 10 μg/kg 2 hours after irradiation could improve the symptoms of fever and bleeding, increase the nadir of peripheral red blood cells and platelets counts, shorten the duration of hemocytopenia, and advance the time for blood cells to return to the pre-irradiation level. The serum biochemical results showed that rhTPO could improve the abnormality of serum biochemical indexes in rhesus monkeys induced by 5.0 Gy total body irradiation to some extent. Compared with the two administration groups, the therapeutic effect of rhTPO 10 μg/ kg was better. CONCLUSION A single injection of rhTPO 5 μg/ kg or 10 μg/ kg 2 hours after irradiation can alleviate the injury of multilineage hematopoiesis and promote the recovery in monkeys irradiated by 5.0 Gy γ-ray. It also improves animal signs and has obvious therapeutic effect on acute radiation sickness.

Objective: To explore the efficacy and feasibility of transanal hand-sewn reinforcement of low stapled anastomosis in preventing anastomotic leak after transanal total mesorectal excision (taTME). Methods: A descriptive cohort study was conducted. Clinical data of 51 patients with rectal cancer who underwent taTME with transanal hand-sewn reinforcement of low stapled anastomosis at Department of Colorectal Surgery, the Sixth Affiliated Hospital of Sun Yat-sen University from January 2019 to December 2020 were retrospectively collected. Inclusion criteria: (1) age >18 years old; (2) rectal cancer confirmed by preoperative pathology; (3) distance from tumor to anal verge ≤ 8 cm according to pelvic MR; (4) the lesion was evaluated to be resectable before operation; (5) with or without neoadjuvant chemotherapy and radiotherapy; (6) taTME, end-to-end stapled anastomosis, and reinforcement in the anastomosis with absorbable thread intermittently were performed, and the distance between anastomosis and anal verge was ≤ 5 cm. Exclusion criteria: (1) previous history of colorectal cancer surgery; (2) emergency surgery due to intestinal obstruction, bleeding or perforation; (3) patients with local recurrence or distant metastasis; (4) the period of postoperative follow-up less than 3 months. The procedure of transanal hand-sewn reinforcement was as follows: firstly, no sign of bleeding was confirmed after checking the anastomosis. Then, the anastomosis was reinforced by suturing the muscle layer of rectum intermittently in a figure-of-eight manner using 3-0 single Vicryl. The entry site of the next suture was close next to the exit site of the last one. Any weak point of the anastomosis could also be reinforced according to the specimen from the circular stapler. The primary outcome were the incidence of anastomotic leak, methods of the secondary operation, anastomotic infection, anastomotic stricture, and conditions of Intraoperative and postoperative. Results: All the 51 enrolled patients completed surgery successfully without any conversion to open surgery. The median operative time was 169 (109-337) minutes, and the median intraoperative blood loss was 50 (10-600) ml. The median postoperative hospital stay was 8 (5-16) days. The mssorectum was complete and distal resection margin was negative in all patients. Postive circumferential resection margin was observed in 1 patients (2.0%). Twelve (23.5%) patients underwent prophylactic ileostomy. One patient developed anastomosis stricture which was cured by digital dilatation of the anastomosis. ISREC grade C anastomotic leak was observed in 3 (5.9%) male patients, of whom 2 cases did not received prophylactic ileostomy during the operation, and were cured by a second operation with the ileostomy and anastomotic repair. The other one healed by transanal repair of the anastomosis and anti-infection therapy. One (2.0%) patient suffered from perianal infection and healed by sitz bath and anti-infection therapy. No death was reported within 30 days after operation. Conclusion: Transanal hand-sewn reinforcement in low rectal stapled anastomosis in preventing anastomotic leak after taTME is safe and feasible.
