The total effective rate of TCM syndrome effectiveness in the treatment group was 88.89% （40/45）， which was better than 66.67% （30/45） in the control group （P＜0.05）； and the rate of atrial fibrillation regression in the treatment group was 26.67% （12/45）， better than 6.67% （3/45） in the control group （P＜0.05）. The number and duration of atrial fibrillation episodes in both groups were significantly decreased （P＜0.01）， and the number and duration of atrial fibrillation episodes in the treatment group were lower than those in the control group （P＜0.01）. The TCM syndrome scores of both groups after treatment were significantly lower than before treatment （P＜0.01）， and the scores of the treatment group was lower than those of the control group （P＜0.05）. The severity of atrial fibrillation symptoms and the grading of atrial fibrillation symptoms in both groups after treatment were improved （P＜0.01）， and the degree of symptom improvement in the treatment group was better than that in the control group （P＜0.01）. The 24-hour average ventricular rate of both groups after treatment was significantly lower （P＜0.01）. The PSQI， anxiety index and depression index of the treatment group were all lower than before treatment （P＜0.01）， while the PSQI and anxiety index of the control group were both lower than before treatment （P＜0.01 or P＜0.05）， the PSQI， anxiety index and depression index of the treatment group being lower than those of the control group （P＜0.05 or P＜0.01）. No adverse events occurred in both groups， and no abnormalities were observed in blood， urine， stool routine， liver and kidney function， and coagulation function indexes. ConclusionDingchan Granule for paroxysmal atrial fibrillation with qi stagnation and blood stasis syndrome can alleviate clinical symptom， improve TCM symptom scores， increase atrial fibrillation recovery rate， stabilise the average ventricular rate， and significantly improve the quality of sleep， alleviate the anxiety and depression， with a good safety profile.

Objective To evaluate the effectiveness and safety of quadruple regimen in preventing multi-day cisplatin-based chemotherapy-induced nausea and vomiting(CINV).Methods A total of 112 patients with malignant tumors who underwent cisplatin-based chemotherapy.According to the random number table method,patients were divided into the experimental group and the control group,with 56 cases in each group.The control group received cisplatin-based chemotherapy and triple therapy of fosapreitant dimeglumine,ondansetron hydrochloride and dexamethasone tablets.On this basis,the experimental group was given quadruple therapy containing olanzapine tablets.The occurrence of nausea and vomiting,as well as changes in FLIE and HAD scores were observed in both groups.Results The incidence of nausea and vomiting was lower from day 1(D1)to day 9(D9)after the beginning of chemotherapy in the experimental group than that in the control group(P＜0.05).The incidence of nausea and vomiting in the experimental group was lower than that in the control group.On D9 after the beginning of chemotherapy,the nausea score,vomiting score and total score of FILE were higher in the experimental group than those in the control group(P＜0.05).There were no significant differences in depression or anxiety score and incidence of adverse reactions on D1 and D9 after the beginning of chemotherapy between the two groups(P＞0.05).Conclusion The quadruple antiemetic regimen can improve the control rate of CINV induced by multi-day cisplatin-based chemotherapy,especially for the control of delayed nausea and vomiting,and improve the quality of life of patients during chemotherapy,with good safety.

Objective:To obtain the normal reference range of hemodynamic ultrasound parameters after pediatric liver transplantation through big data query and statistical analysis, and compare their changes with age.Methods:The clinical liver transplantation ultrasound imaging database software V1.0 independently developed by Tianjin First Central Hospital was used to query the ultrasound hemodynamic parameters of 0-14 years old pediatric patients after parental liver transplantation from December 2012 to December 2022, including portal vein diameter (PVD) on the 1st day, 7th day, 1st month, 6th month, 1st year, 5th year, and 10th year after surgery. The changes in ultrasound blood flow parameters such as portal vein velocity (PVV), hepatic artery peak velocity (S), hepatic artery end diastolic velocity (D), and left hepatic vein velocity (LHVV) with postoperative time in different age groups were analyzed, the differences between age groups were compared, and statistical analysis was perform to obtain the 95% reference value range for each parameter.Results:A total of 731 pediatric patients aged 0-14 years who underwent parental liver transplantation were included in this study, with a total of 5 283 monitoring results. The ultrasound hemodynamic parameters PVV, hepatic artery S, D, and LHVV were highest at 7th day after surgery, and gradually showed a sustained and slightly decreasing trend with the prolongation of postoperative time. At the same time, there was no statistically significant difference in PVV, hepatic artery S, D, and LHVV among different age groups (all P>0.05). Conclusions:This study obtains the trend of ultrasound hemodynamic parameters after pediatric liver transplantation with prolonged follow-up time, and compared them among different age groups.After pediatric liver transplantation, there is no significant change in liver hemodynamic parameters with increasing age. Obtaining reference value ranges for various parameters in different age groups is of great clinical significance for early detection and diagnosis of postoperative vascular complications. Pediatric liver transplantation is more complex than adult liver transplantation, and in clinical monitoring, more attention should be paid to the dynamic changes of transplanted liver blood flow, combining with individual patient status, to provide imaging support for clinical diagnosis.

Objective To investigate the analgesic effect of multi-site multiple paravertebral nerve blocks on patients undergoing radical lung cancer surgery and the impact on their serum indices and prognosis.Methods Ninety-eight cases of patients undergoing thoracoscopic radical lung cancer surgery in our hospital were selected from March 2021 to January 2023 and divided into 2 groups according to the difference in anaesthesia.Among them,42 patients in the study group were treated with preoperative and postoperative multipoint paravertebral nerve block combined with general anaesthesia,while 56 patients in the control group were treated with preoperative multipoint paravertebral nerve block combined with general anaesthesia,and the analgesic effect and other differences between the two groups were compared.Results In the study group,extubation time,recovery time,propofol dosage and postoperative VAS score were(150.2±15.2)min,(19.1±5.1)min,(738.2±36.5)mg and(4.2±0.7)points,respectively.The control group was(151.9±12.6)min,(22.6±7.3)min,(902.1±49.0)mg and(2.3±0.3)min,respectively,and the difference between the two groups was statistically significant(P＜0.05).The differences of heart rate,mean arterial pressure and before and after half an hour after surgery in control group were higher than those in study group,and the differences of norepinephrine,epinephrine and before and after surgery were higher than those in study group,with statistical significance(P＜0.05).The total complication rate of the study group was 7.2％,and that of the control group was 23.2％.The QoR score of the control group was lower than that of the study group,and the difference between the two groups was statistically significant(P＜0.05).Conclusion Preoperative and postoperative multi-point paravertebral nerve block combined with general anaesthesia has a better analgesic effect on patients undergoing radical lung cancer surgery,which can not only reduce the inflammatory reaction of the patients,but also have less impact on their haemodynamic indexes and lower rate of postoperative adverse reactions,and ultimately improve the quality of life of the patients.

Objective:To explore the characteristics of postoperative hemodynamic changes in patients with early allograft dysfunction (EAD), and to provide clinical imaging support for the early diagnosis of EAD.Methods:A total of 907 patients who underwent liver transplantation in Tianjin First Central Hospital from December 2012 to June 2021 were retrospectively selected, and they were divided into EAD group (361 cases) and non-EAD group (546 cases) according to EAD diagnostic criteria. The peak systolic velocity(PSV) of the hepatic artery, end-diastolic velocity(EDV) of the hepatic artery, resistance index(RI), S/D(PSV/EDV), diameter of the portal vein(PVD), velocity of the portal vein(PVV), diameter of the middle hepatic vein(MHVD), velocity of the middle hepatic vein(MHVV), the diameter of the right hepatic vein(RHVD), and the velocity of the right hepatic vein (RHVV) were collected from 1 to 7 days after operation (a total of 5 573 ultrasound examination results), and the differences in ultrasound hemodynamic parameters were compared between the two groups. The correlation of S/D<2, PSV<25 cm/s, PVV<15 cm/s, MHVV or RHVV<15 cm/s within 3 days after operation with the occurence of EAO were analyzed by multivariate Logistic regression analysis.Results:①The PSV and EDV of the hepatic artery in the EAD group and the non-EAD group showed a slow upward trend at 1-7 days after operation, while the hepatic artery RI and PVV showed a downward trend, the MHVV and RHVV did not fluctuate significantly. ②The hepatic artery in the EAD group showed low-resistance blood flow in the early postoperative period, and the EDV were significantly higher than that in the non-EAD group on 1 d, 2 d, 3 d and 5 d, RI was significantly lower than that of the non-EAD group (all P<0.05); At 4 d, 6 d and 7 d, there was no significant differences of EDV and RI between the two groups(all P>0.05). The PSV of the EAD group was higher than that of the non-EAD group on 3 d ( P<0.05). Among the parameters of portal vein blood flow, the PVV in the EAD group was significantly higher than that in the non-EAD group on 1 d ( P<0.05), and there was no significant difference of PVD between the two groups at day 1-7. Among the parameters of hepatic venous blood flow, the MHVV and RHVV in the EAD group were significantly lower than those in the non-EAD group (all P<0.05), there was no significant difference between the two groups of MHVD and RHVD at 1-7 days. ③The incidence of grafted hepatic artery S/D<2 within 3 days after operation in EAD group was higher than that in non-EAD group. Binary Logistic regression multivariate analysis showed that the occurrence of grafted hepatic artery S/D<2 within 3 days after operation was significantly correlated with the occurrence of EAD[Exp(B)=1.878, P<0.05]. Conclusions:Patients who develop EAD after liver transplantation show low-resistance blood flow in the hepatic artery during the perioperative period, and the occurrence of hepatic artery S/D<2 within 3 days after operation can early predict the occurrence of EAD.

Objective:To investigate the correlation between Doppler ultrasound parameters and pressure gradient of portal vein in pediatric liver transplant patients, and to analyze the diagnostic value of Doppler ultrasound for portal vein stenosis.Methods:This retrospective study involved the data from 92 pediatric liver transplant patients in Tianjin First Central Hospital from June 2014 to September 2021, who underwent pressure gradient measurement. The collected ultrasonic parameters included the diameter and flow velocity of the native portal vein, the portal vein anastomosis, and the donor portal vein. The anastomotic stenosis rate=(the native portal vein diameter–the portal vein anastomosis diameter)/the native portal vein diameter, the velocity ratio=the portal vein anastomosis velocity /the native portal vein velocity, the velocity difference=the portal vein anastomosis velocity–the native portal vein velocity. According to the diagnostic standard of portal vein stenosis, pressure gradient more than 5 mmHg was the portal vein stenosis group, and the pressure gradient less than 5 mmHg was the non-stenosis group. The correlation and differences between ultrasonic parameters and pressure gradient were analyzed. ROC curve was used to evaluate the diagnostic efficiency of each parameter.Results:Firstly, there was a positive correlation between pressure gradient and the portal vein anastomosis velocity, the velocity difference and the velocity ratio ( r=0.521, 0.531, 0.417; all P<0.001). And there was a negative correlation between pressure gradient and the anastomotic diameter ( r=-0.284, P=0.004). Secondly, the portal vein anastomotic velocity, velocity difference and velocity ratio in stenosis group were significantly higher than those in non-stenosis group [135.5(111.0, 169.0)cm/s vs 103.7(72.9, 118.7)cm/s, (112.2±40.3)cm/s vs (67.9±30.5)cm/s, 5.56(3.73, 7.26) vs 3.85(2.78, 4.70); all P≤0.001]; Furthermore, by ROC curve analysis, the cut-off value, the area under the ROC curve, Jordan index, accuracy, sensitivity and specificity of each parameter for the diagnosis of portal vein stenosis were: the anastomotic velocity 124.5 cm/s, 0.814, 0.592, 80.0%, 65.5% and 93.7%; velocity ratio 5.67, 0.760, 0.488, 73.0%, 48.8% and 100%; velocity difference 107.25 cm/s, 0.797, 0.511, 76.0%, 51.9% and 100%. Conclusions:The anastomosis velocity, velocity difference and velocity ratio of portal vein in pediatric liver transplant patients are correlated with the pressure gradient, and there is higher accuracy and specificity of each parameter for diagnosing portal vein stenosis, but the sensitivity is slightly lower.

Compared with normal people, the differences were statistically significant ( tmRNA=0.90, 0.21, 2.85, 1.77; P=0.00, 0.00, 0.04, 0.02. tprotein=1.88, 7.68; P=0.00, 0.02). The cell viability of HRCEC cells in the 3 h hypoxia group and the 6 h hypoxia group were 0.66±0.05 and 0.64±0.04, respectively. Compared with the blank control group, the difference was statistically significant ( F=13.02, P=0.00). The cell viability of HUVEC cells in the 3 h hypoxia group and the 6 h hypoxia group were 0.63±0.06 and 0.68±0.06, respectively. Compared with the blank control group, the difference was statistically significant ( F=26.52, P=0.00). Comparison of FSTL1, TGF-β1, CTGF, and VEGF mRNA expression in HRCEC blank control group and 3 h hypoxia group, the differences were statistically significant ( F=14.75, 44.93, 85.54, 6.23; P=0.01, 0.00, 0.00, 0.03). Compared with the HRCEC blank control and 3 h hypoxia group, the expressions of FSTL1 and TGF-β1 protein were statistically significant ( P<0.05). There was a statistically significant difference in TGF-β1 protein expression in the hypoxic 6 h group ( P=0.03) and no significant difference in FSTL1 protein expression ( P=0.68). Comparison of FSTL1, TGF-β1, CTGF, and VEGF mRNA expression in HUVEC blank control group and 3h hypoxia group, the differences were statistically significant ( F=19.08, 25.12, 22.89, 13.07; P=0.00, 0.00, 0.00, 0.01). Immunofluorescence staining results showed that FSTL1, TGF-β1, CTGF, and VEGF proteins were positively expressed in cells in the 3h hypoxia and 6h hypoxia groups. Conclusion:The expression of FSTL1 gene and protein in serum of PDR patients was significantly higher than that of normal people.

Objective:To observe the changes in refractive status of eyes with idiopathic macular hole (IMH) after vitrectomy and phacoemulsification and IOL implantation (combined surgery).Methods:A retrospective clinical study. From January 2016 to June 2019, 51patients (56 eyes) of IMH who underwent combined surgery at the Tianjin Medical University Eye Hospital. were included in the study. Among them, there were 17 males and 34 females with the average age of 66.79±4.33 years. All the affected eyes underwent BCVA, retinoscopy and axial length (AL) measurement. The IOL power was calculated according to the SRK-T formula and the refractive power (predicted value) was predicted. The average BCVA of the affected eye was 0.20±0.13. The average anterior chamber depth was 2.89±0.28 mm. The average △corneal astigmatism was 0.73±0.43 D, the average AL was 22.92±0.70 mm, the average predicted refractive power was 0.10±0.66 D. All the affected eyes underwent standard transciliary flat part three-channel 25G combined surgery. Six months after the operation, the actual value (actual value) of the diopter after the operation was measured with the same equipment and method before the operation. Paired t test was used to compare the difference between the predicted value and the actual value. Results:Six months after the operation, the actual value of the refractive power was -0.19±0.64 D. Compared with the pre-operative refractive power, the difference was not statistically significant ( t=1.665, P=0.102). The difference between the actual value and the predicted value was -0.33± 0.81 D. Conclusions:The refractive status of the IMH eye undergoes myopia drift after combined surgery. The preoperative IOL power budget can be appropriately reserved for +0.3 D hyperopia.

The expressions of IGF1R, Ras, RAGE and HMGB1 in cancer tissues were detected by immunohistochemistry. The differences between the two groups were compared and the relationship between the expression and clinicopathological characteristics was analyzed.Results:In CRC/DM group, the positive rates of IGF1R and Ras were both 65.5% (19/29), and 51.7% (15/29) patients had IGF1R+ Ras+ immunophenotype, which were significantly higher than those in CRC group [33.3% (10/30), 36.7% (11/30) and 20.0% (6/30); P=0.013, 0.027 and 0.011, respectively]. The expression of IGF1R and Ras in CRC / DM group was positively correlated ( r=0.479, P=0.017). The positive rate of RAGE expression in CRC group and CRC/DM group was 70.0% (21/30) and 72.4% (21/29) respectively, and the positive rate of HMGB1 expression was 46.7% (14/30) and 58.6% (17/29) respectively, neither was observed with significant difference ( P=0.358 and 0.838). However, the proportion of patients with RAGE+ HMGB1+ immunophenotype in CRC/DM group [55.2% (16/29)] was higher than that in CRC Group [26.7% (8/30)] which was statistically significant ( P=0.026), and the expression of both proteins was positively correlated in CRC/DM group ( r=0.578, P=0.003). The clinicopathological analysis showed that in both groups the expression of IGF1R, Ras, RAGE and HMGB1 had no correlation with the sex, age, differentiation degree, tumor length, T stage and lymph node metastasis ( P>0.05). Conclusion:Both IGF1R-Ras and RAGE-HMGB1 pathways may be involved in the oncogenesis of colorectal cancer in patients with type 2 diabetes.
