We conducted a prospective study to assess the non-inferiority of adjuvant chemotherapy alone versus adjuvant concurrent chemoradiotherapy (CCRT) as an alternative strategy for patients with early-stage (FIGO 2009 stage IB-IIA) cervical cancer having risk factors after surgery. The condition was assessed in terms of prognosis, adverse effects, and quality of life. This randomized trial involved nine centers across China. Eligible patients were randomized to receive adjuvant chemotherapy or CCRT after surgery. The primary end-point was progression-free survival (PFS). From December 2012 to December 2014, 337 patients were subjected to randomization. Final analysis included 329 patients, including 165 in the adjuvant chemotherapy group and 164 in the adjuvant CCRT group. The median follow-up was 72.1 months. The three-year PFS rates were both 91.9%, and the five-year OS was 90.6% versus 90.0% in adjuvant chemotherapy and CCRT groups, respectively. No significant differences were observed in the PFS or OS between groups. The adjusted HR for PFS was 0.854 (95% confidence interval 0.415-1.757; P = 0.667) favoring adjuvant chemotherapy, excluding the predefined non-inferiority boundary of 1.9. The chemotherapy group showed a tendency toward good quality of life. In comparison with post-operative adjuvant CCRT, adjuvant chemotherapy treatment showed non-inferior efficacy in patients with early-stage cervical cancer having pathological risk factors. Adjuvant chemotherapy alone is a favorable alternative post-operative treatment.

Objective:To investigate the types, incidences, and clinical characteristics of shock in polytrauma patients at different stages after polytrauma.Methods:A retrospective study was conducted on polytrauma patients admitted to multiple trauma centers from June 2020 to December 2021. The inclusion criteria were patients >18 years old and treated due to polytrauma. Exclusion criteria included an admission time of more than 48 h after trauma, a history of malignancy, or metabolic, consumptive, and immunological diseases. The early stage was defined as the period of ≤48 h after polytrauma, and the middle stage was defined as the period between 48 h and 14 days. The patient’s medical history, clinical manifestations, laboratory tests, imaging examination, injury severity score (ISS), and Glasgow coma scale (GCS) were collected. The types, incidences, and clinical characteristics of shock in different stages after polytrauma were analyzed, according to the diagnostic criteria of each type of shock. The differences between the groups were compared by Student’s t test, χ2 test or Mann-Whitney U test. Results:The incidence of the early and middle stage shock after polytrauma were 73.1% and 36.4%, respectively, with statistically significant difference between stages ( P<0.01). There were significant differences in the incidence of hypovolemic shock (83.6% vs. 28.4%), distributed shock (13.7% vs. 80.9%) and cardiogenic shock (3.5% vs. 6.6%) between stages (all P<0.05). The incidence of obstructive shock (8.4% vs. 9.7%, P>0.05) was similar between stages. The incidence of undifferentiated shock was 1.6% and 1.2%, respectively. There were 9.5% patients with multifactorial shock in the early stage and 14.4% in the middle stage. Totally 7 combinations of multifactorial shock were found in different stages after polytrauma. In the early stage, the combination of HS and DS accounted the highest ratio (42.3%) and followed by HS and OS for 28.8%. In the middle stage, the combination of HS and DS was the most common (48.6%) and followed by DS and OS (24.3%). Conclusions:The incidence of shock in polytrauma patients is high. Different types of shock can occur simultaneously or sequentially. Therefore a comprehensive resuscitation strategy is significant to improve the success rate of treatment.

Objective:To retrospectively assess early risk factor of persistent inflammation, immunosuppression and catabolism syndrome (PICS) in patients with severe polytrauma, in order to deepen the understanding of the pathological changes of chronic critical illness (CCI) after severe polytrauma.Methods:A total of 276 patients with severe polytrauma admitted to Department of Trauma Surgery of Tongji Hospital from March 2019 to December 2020 were enrolled. Inclusion criteria included patients who suffered severe polytrauma, and injury severity score (ISS) ≥27, age ≥18 years old, and had length of hospital stay >15 days. Exclusion criteria included previous medical history of malignancy, or immunological, consumptive, and metabolic diseases. The patient’s clinical characteristics, ISS scores, Glasgow coma scale (GCS), sequential organ failure assessment, APACHEⅡ scores, and nutrition and immune indexes on day 3 after injury were collected. The difference between the PICS group and N-PICS group were performed by Student’s t test, χ2 test or Mann-Whitney U test. The early risk factors were assessed in patients with PICS after severe polytrauma by logistic regression analysis. Results:According to the diagnostic criteria of PICS, all enrolled patients were divided into two groups: PICS group ( n=102) and N-PICS group (without PICS, n=174). Compared with the N-PICS group, patients in the PICS group were older and associated with more brain and chest injuries. On the third day after injury, serum levels of IL-6 and IL-10, and the ratio of Treg cells were significantly higher, the number and ratio of NK cells subset, and the ratio of activated T lymphocyte were significantly lower in the PICS group than in the N-PICS group ( P<0.05). Logistic regression analysis showed that the age>65 years old ( OR=2.375, 95% CI: 1.442-4.531), GCS ≤8 scores ( OR=3.431, 95% CI: 1.843-8.512), IL-10 >10 pg/mL ( OR=2.173, 95% CI: 1.751-5.614), the ratio of Treg cells >7% ( OR=3.871, 95% CI: 1.723-6.312), and the occurrence of traumatic brain and chest injuries ( OR=2.846, 95% CI: 1.522-5.361) were the early risk factors in patients with PICS after severe polytrauma. Conclusions:Age>65 years old, GCS score, IL-10, the ratio of Treg cells, and the occurrence of traumatic brain and chest injuries could be used as the early risk factors in patients with PICS after severe polytrauma. The discovery of early risk factors will help identify patients at high risk of PICS after severe polytrauma, and create the possibility for early intervention.

Objective:To retrospectively assess the relationship between immune disorder and acute gastrointestinal injury (AGI) in patients after severe polytrauma.Methods:Totally 205 patients with severe polytrauma admitted to Tongji Hospital from April 2018 to October 2019 were enrolled as the observation group, and 23 healthy volunteers were served as the control group. According to the diagnostic criteria of AGI, all patients were divided into the AGI group (with AGI) or N-AGI group (without AGI), AGI patients were divided into the S-AGI group or L-AGI group according to the severity. The levels of cytokines and lymphocyte subset were evaluated at day 1, 7, and 14 after severe polytrauma. The differences between groups were statistically analyzed. The independent risk factors of AGI were analyzed by Logistic regression analyzed.Results:Totally 79.5% (163/205) of patients with severe polytrauma were accompanied by AGI. There were significant differences in the ratio of Tc, Th at day 1 after trauma, the levels of IL-6, TNF-α, IL-8, IL-10, the ratio of Ts, Th/Ts, Treg at day 7 after trauma, and the levels of IL-8, IL-10,the ratio of Ts, Th/Ts, Treg at day 14 after trauma between the AGI group and N-AGI group ( P<0.05). There were significant differences in the ratio of Tc, Th, the levels of IL-6, TNF-α at day 1 after trauma and the ratio of Ts, Th/Ts, Treg, the levels of IL-8, IL-10 at day 7 and 14 after trauma between the S-AGI group and L-AGI group ( P<0.05). Logistic regression analysis showed that Ts 7 d ( OR=2.018, 95% CI: 1.105-5.364, P=0.013), Treg 14 d ( OR=3.612, 95% CI: 1.375-8.476, P=0.006), IL-6 7 d ( OR=1.824, 95% CI: 1.011-5.835, P=0.024), IL-10 14 d ( OR=2.847, 95% CI: 1.241-6.216, P=0.014), TNF-α 7 d ( OR=1.754, 95% CI: 1.215-5.441, P=0.018) were independent risk factors in patients with AGI after severe polytrauma. Conclusions:AGI is more easily occurred in patients with the heavier immune disorders after severe polytrauma. AGI can also aggravate pre-existing immune disorders in patients after severe polytrauma.

Objective:To retrospectively assess the occurrence and risk factors in patients with acute gastrointestinal injury (AGI) after polytrauma.Methods:Totally 430 patients with polytrauma admitted to Tongji Hospital from April 2018 to October 2019 were enrolled as the observation group. According to the diagnostic criteria of AGI, all patients were divided into the AGI group (with AGI) or N-AGI group (without AGI). The patients with abdominal injury or previously suffered from gastrointestinal disease were excluded. The patient's clinical characteristics lab tests results, and the first ISS, APACHEⅡ, SOFA and GCS scores were collected. The differences between different groups were statistically analyzed. The independent risk factors of AGI were analyzed by Logistic regression.Results:65.3% of patients with polytrauma were accompanied by AGI (281/430 cases).There were significant differences between the AGI group and N-AGI group in ISS, GCS, APACHE Ⅱ and SOFA score, PCT or IL-6 level, shock index and length of stay in ICU ( P<0.05). Logistic regression analysis showed that shock, ISS≥16, APACHE Ⅱ≥16, SOFA≥5, GCS≤8 and IL-6>50 pg/mL were the early independent risk factors in patients with ACI after polytrauma. Conclusion:The incidence of AGI in patients after polytrauma is higher, which is related to ischemia, hypoxia, abnormal blood coagulation and stress in the early stage after trauma.

Objective To discuss the angiographic manifestations of hemorrhage after pancreaticoduo-denectomy (PD), and to evaluate the clinical curative effect of interventional therapy. Methods The angiographic findings and the therapeutic effect of interventional therapy for hemorrhage after PD in 19 PD patients, who were admitted to Fujian Provincial Hospital, China, during the period from January 2014 to February 2018 to receive DSA examination and interventional therapy, were retrospectively analyzed. Results Among the 19 PD patients, DSA examination showed that extravasation of contrast medium, pseudoaneurysm formation and irregular arterial lumen were observed in 16 patients, the rate of positive signs was 84.2％ (16/19) . All the 16 patients, who had positive DSA findings, received covered-stent implantation or embolization therapy for the responsible artery, except one patient who had hemorrhage from the branch of superior mesenteric artery and the super-selective catheterization for him failed. The technical success rate was 93.8％ (15/16) . Successful hemostasis was achieved in 13 patients (86.7％, 13/15) . Two patients developed recurrent bleeding and were transferred to surgical treatment. Two patients received twice angiography, the resultsshowed that pseudoaneurysm formation of gastroduodenal artery was detected in one patient, which was treated with embolization therapy, and in another patient angiography was normal and this patient was transferred to surgical treatment. Conclusion For postoperative hemorrhage of PD, DSA has diagnostic value, while interventional therapy has therapeutic value. The techniques are minimally-invasive and highlyeffective. Therefore, it is worthy of clinical popularization and application.

Tung tree (Vernicia fordii) is an economically important woody oil plant that produces tung oil rich in eleostearic acid. Here, we report a high-quality chromosome-scale genome sequence of tung tree. The genome sequence was assembled by combining Illumina short reads, Pacific Bio-sciences single-molecule real-time long reads, and Hi-C sequencing data. The size of tung tree gen-ome is 1.12 Gb, with 28,422 predicted genes and over 73％ repeat sequences. The V. fordii underwent an ancient genome triplication event shared by core eudicots but no further whole-genome duplication in the subsequent ca. 34.55 million years of evolutionary history of the tung tree lineage. Insertion time analysis revealed that repeat-driven genome expansion might have arisen as a result of long-standing long terminal repeat retrotransposon bursts and lack of efficient DNA deletion mechanisms. The genome harbors 88 resistance genes encoding nucleotide-binding sites;17 of these genes may be involved in early-infection stage of Fusarium wilt resistance. Further, 651 oil-related genes were identified, 88 of which are predicted to be directly involved in tung oil biosynthesis. Relatively few phosphoenolpyruvate carboxykinase genes, and synergistic effectsbetween transcription factors and oil biosynthesis-related genes might contribute to the high oil content of tung seed. The tung tree genome constitutes a valuable resource for understanding genome evolution, as well as for molecular breeding and genetic improvements for oil production.

Objective? To explore the clinical application effects of the spring stiffener for laparoscopic camera cable. Methods? Self-designed laparoscopic camera cable spring reinforcement and the camera was used in clinical practice since January 2017. The maintenance frequency of laparoscopic camera and the operative satisfaction of 49 surgical doctors using the camera were measured between January and December 2016 and between January and December 2017 in the operation room of the First Affiliated Hospital of Wenzhou Medical University. The difference was compared between the two groups before and after improvement. Results? There was statistical difference in the maintenance frequency of the 22 laparoscopic cameras before and after improvement (P＜ 0.05); there was statistical difference in the surgical doctors' overall operative satisfaction, surgical interruption, picture clarity, surgical collaboration and surgical progress (P＜0.05), and the satisfaction after improvement was higher than that before improvement. Conclusions? The spring stiffener for laparoscopic camera cable can not only reduce the frequency of camera maintenance, but also improve the satisfaction of the surgical doctors using the camera, which is worth promoting in clinical practice.
