Objective To study the diagnostic and prognostic value of serum soluble triggering receptor expressed on myeloid cell-1 (sTREM-1) and cyclooxygenase-2 (COX-2) in abdominal infection-caused sepsis. Methods A total of 170 patients with abdominal infection treated in the First Hospital of Qinhuangdao between January 2019 and March 2022 were retrospectively selected and divided into sepsis group (n=76) and non-sepsis group (n=94) according to whether they were combined with abdominal infection-caused sepsis. In addition, 80 healthy people in the same period were selected as the control group. The levels of serum sTREM-1 and COX-2 in the three groups were detected and the differences were compared. The laboratory indexes, including white blood cell count, high-sensitivity C-reactive protein, and procalcitonin of patients with abdominal infection-caused sepsis were detected. The Sequential Organ Failure Assessment score, Acute Physiology and Chronic Health Evaluation System Ⅱ and prognosis (survival or death) of patients with abdominal infection-caused sepsis were evaluated. The correlations of serum sTREM-1 and COX-2 with the severity of sepsis were analyzed, and the diagnostic and prognostic value of sTREM-1 and COX-2 in abdominal infection-caused sepsis was assessed. Results The levels of serum sTREM-1 and COX-2 in the sepsis group were higher than those in the control group and the non-sepsis group (P<0.05). The levels of serum sTREM-1 and COX-2 in the sepsis group were positively correlated with white blood cell count, high-sensitivity C-reactive protein, procalcitonin, Sequential Organ Failure Assessment score, Acute Physiology and Chronic Health Evaluation System Ⅱ score (P<0.05). The serum levels of sTREM-1 and COX-2 of patients who died during hospitalization in the sepsis group were higher than those of the surviving patients. The areas under the receiver operating characteristic curves of the serum sTREM-1 and COX-2 levels for diagnosing sepsis caused by abdominal infection were 0.814 [95% confidence interval (CI) (0.746, 0.882), P<0.001] and 0.848 [95%CI (0.788, 0.905), P<0.001], respectively, with critical values of 1.879 pg/mL and 18.75 ng/mL, respectively, and those for predicting the prognosis of patients with sepsis caused by abdominal infection were 0.775 [95%CI (0.659, 0.890), P<0.001] and 0.784 [95%CI (0.679, 0.889), P<0.001], respectively, with critical values of 2.283 pg/mL and 23.02 ng/mL, respectively (P<0.05). Conclusion The serum levels of sTREM-1 and COX-2 have certain value in the diagnosis and prognosis prediction of abdominal infection-caused sepsis.
ObjectiveTo analyze the death causes of postoperative early-stage after orthotopic liver transplantation (OLT) in rats, and to provide appropriate treatment strategies. MethodsThree hundreds of rat OLT models were performed by modified Kamada two-cuff technique. Operation time of each stage during OLT and postoperative survival time of rats were recorded and analyzed. According to survival time, the rats were divide into 4 groups:intraoperative death group (rats died during operation), < 6 hours group, 6-24 hours group, and > 24 hours group. Then comparison of operation time of each stage during OLT in rats of 4 groups was performed, and reasons of death during 24 hours after OLT were analyzed. ResultsOf the 300 OLT models, 37 rats died during operation (12.33%), 51 rats died within 6 hours after operation (17.00%), 76 rats died during 6-24 hours after operation (25.33%), and 136 rats survived longer than 24 hours (45.34%). The most common death causes of < 6 hours group were as follows:lose too much blood during the operation (27.45%, 14/51), postoperative bleeding (27.45%, 14/51), and vascular embolization (15.69%, 8/51). However, the most common death causes of 6-24 hours group were as follows:angiostenosis (27.63%, 21/76), postoperative bleeding (21.05%, 16/76), and pulmonary edema (19.74%, 15/76). There were significant differences in the cold ischemia time and anhepatic phase among the 4 groups (P < 0.05). The cold ischemia time and anhepatic phase of intraoperative death group were longer than those of other 3 groups (P < 0.05), in addition, the cold ischemia time of > 24 hours group was shorter than those of other 3 groups (P < 0.05). ConclusionsThere are many reasons leading to the early death after OLT. The long time of anhepatic phase and the cold ischemia time, intraoperative and postoperative bleeding, thrombosis, angiostenosis, and pulmonary edema are key factors for the improvement of prognosis in rats after OLT operation. Improvements of the reasons above are helpful to improve the successful rate of modeling and quality of OLT rats.

ObjectiveTo analyze the status and influencing factors of awareness of diabetic retinopathy (DR) knowledge in diabetics in Funing County, Jiangsu Province. MethodsThis is a cross-sectional study. In 2021, a total of 2 125 residents with diabetes in Funing County, Jiangsu Province were recruited using cluster random sampling methods. General examinations were performed and ophthalmological evaluation were conducted including visual acuity in daily life, slit lamp microscope with preset lens, digital non-mydriatic fundus photography. Clinical assessment and classification of DR were according to the international standard clinical classifications of diabetic retinopathy in 2019. DR was classified into no obvious DR, mild non-proliferative diabetic retinopathy (NPDR), moderate NPDR, severe NPDR and proliferative diabetic retinopathy (PDR). Field questionnaire surveys were conducted to show the awareness rate of DR knowledge. Then Chi-square test and Logistic regression analysis were used to investigate influencing factors. ResultsAmong 2 125 subjects, 762 (35.86%, 762/2 125) residents were male and 1 363 (64.14%, 1 363/2 125) residents were female. A total of 444 (20.89%, 444/2 125) subjects were diagnosed as DR. Among which, 438 (20.61%, 438/2 125) subjects were NPDR, 6 (0.28%, 6/2 125) subjects were PDR. A total of 419 (19.72%, 419/2 125) subjects were diagnosed as cataract. The topic awareness rates were all below 45.00%. The overall population awareness rate was 19.45% (4 959/25 500). Awareness rate was correlated with age, visual acuity in daily life, education level, family history of diabetes, diabetic retinopathy grades and the type of treatment for diabetes (P＜0.001). Logistic regression analysis showed that the knowledge rate of prevention and treatment of DR Decreased significantly in patients aged 60-79 compared with those aged under 50 (P＜0.05). Compared with those with visual acuity＜0.1 in daily life, the knowledge rate of DR prevention and treatment in those with visual acuity≥0.1 was significantly decreased (P＜0.05). While primary school to college education, with family history of diabetes, with DR, oral hypoglycemic agents and/or insulin treatment were associated with higher awareness rate (P＜0.05). ConclusionsThe DR knowledge level is low among diabetics in Funing County, Jiangsu Province in 2021. Age, visual acuity in daily life, education level, family history of diabetes, with DR and receiving drug treatments are main influencing factors for diabetic’s awareness.
ObjectiveTo investigate the effectiveness of arthroscopic all-inside combined with outside-in “suture loop” repair for meniscus bucket-handle tear (BHT).MethodsBetween August 2016 and May 2019, 44 case of meniscus BHT were treated with arthroscopic all-inside combined outside-in “suture loop”. There were 29 males and 15 females with an average age of 26.6 years (range, 18-42 years). The causes of injury included sports injury in 31 cases, falling injury in 7 cases, and sprain in 6 cases. There were 32 cases of medial meniscus posterior horn tears and 12 cases of lateral meniscus posterior horn tears. The disease duration ranged from 6 weeks to 3 months. Thirty-three cases were complicated with anterior cruciate ligament rupture. All patients had normal lower limb alignment. The preoperative Lysholm score was 42.1±9.1. According to the evaluation criteria of MRI and Barrett et al., the healing of meniscus was evaluated, and the effectiveness was evaluated by Lysholm score.ResultsAll the 44 patients were followed up 8-36 months with an average of 16.8 months. At last follow-up, according to the evaluation criteria of Barrett et al., 39 cases were clinically healed, 5 cases were not healed, the clinical healing rate was 88.6%; according to MRI evaluation, 32 cases were completely healed, 7 cases were partially healed, and 5 cases were not healed, the total healing rate was 88.6%, and the complete healing rate was 72.7%. Lysholm score was 87.8±4.8, which was significantly different from that before operation (t=31.060, P=0.000).ConclusionArthroscopic all-inside combined with outside-in “suture loop” repair is a reliable and effective method for the meniscus BHT, which can obtain good joint function.
