AIM: To explore the therapeutic effect of oral Xuefu Zhuyu Pill combined with intravitreal injection of aflibercept in the treatment of retinal vein occlusion(RVO).METHODS: A total of 80 patients(80 eyes)with RVO admitted to our hospital from January 2021 to March 2024 were prospectively selected. According to the treatment method, they were divided into a control group of 40 patients treated with intravitreal injection of aflibercept, and an observation group of 40 patients treated with oral Xuefu Zhuyu Pill combined with intravitreal injection of aflibercept. The efficacy, TCM syndrome score, retinal microcirculation parameters, macular edema(ME), and adverse reactions were compared between the two groups of patients in the treatment of RVO.RESULTS: All patients have completed follow-up. The clinical effective rate of the observation group after treatment was 95%, obviously higher than that of the control group(80%; χ2=4.114, P=0.043). After treatment for 3 mo, the traditional Chinese medicine syndrome scores, foveal avascular area(FAZ)area, FAZ circumference, macular central retinal thickness, and neovascularization leakage area of both groups decreased, the overall blood flow density of the superficial capillary plexus(SCP)and deep capillary plexuses(DCP)increased, and the observation group showed better results than the control group(all P<0.05). There was no statistically significant difference in the occurrence of adverse reactions between the two groups during the treatment period(P>0.05).CONCLUSION: Oral administration of Xuefu Zhuyu Pill combined with intravitreal injection of aflibercept in the treatment of RVO can improve retinal microcirculation, enhance vision, restore ocular blood circulation, improve bleeding, promote ME absorption, and improve clinical efficacy.

Objective:To explore and analyze the relationship between serum KLK11 and MK levels and the effect of first iodine 131 ( 131I) ablation after operation for differentiated thyroid cancer. Method:108 patients with differentiated thyroid cancer who underwent total thyroidectomy in our hospital from Jun. 2020 to Jun. 2021 were consecutively selected, and received radioactive ablation after surgery. There were 37 males and 71 females. The age was (48.32±4.25) years, ranging from 28 to 79 years. The patients were divided into successful ablation according to whether the ablation was successful after treatment. There were 64 cases in the group and 44 cases in the unsuccessful group, and 60 healthy people with no abnormality in physical examination during the same period were selected as the control group. The patients were divided into a metastasis-positive group of 20 cases and a metastasis-negative group of 88 cases according to whether lymph nodes occurred. After surgery, serum samples of all subjects were taken, and enzyme-linked immunosorbent assay was used to detect the levels of serum kallikrein-related peptidases 11 (KLK11) and midkine (MK) , and the levels of serum KLK11 and MK were analyzed. Gender, age, BMI, TNM stage, TSH, maximum diameter of lesion, and duration of nail removal were collected. Univariate analysis and logistic regression analysis were used to analyze the independent risk factors of postoperative efficacy.Result:The levels of serum KLK11 and MK in the successful and unsuccessful groups were higher than those in the control group, while the levels of KLK11 and MK in the unsuccessful group were higher than those in the successful group (KLK11: t= 2.642, P<0.05; MK: t=11.906, P<0.05) . The serum levels of KLK11 and MK in the metastasis-positive group were higher than those in the metastasis-negative group (KLK11: t= 2.908, P<0.05; MK: t=14.907, P<0.05) . Univariate analysis showed that BMI ( χ2=6.780, P=0.009) , maximum diameter of lesions ( χ2=14.819, P=0.001) , TSH ( χ2=13.627, P=0.001) , serum KLK11 ( t=2.642, P=0.01) , and serum MK ( t=11.906, P<0.001) were associated with the effect of first 131I ablation after surgery for differentiated thyroid cancer ( P<0.05) . Taking the success of ablation as the dependent variable, a multivariate logistic regression analysis was performed. The results showed that the maximum diameter of the lesions greater than 2 cm ( OR=10.740, 95%CI: 7.033-16.401) , increased level of TSH ( OR=8.559, 95%CI: 2.812-26.057) , increased serum KLK11 level ( OR=16.710, 95%CI: .548-32.666) and increased serum MK level ( OR=10.580, 95%CI: 6.294-17.786) were the factors affecting the first 131I ablation effect after DTC surgery ( P<0.05) . Conclusion:The elevated levels of serum KLK11 and MK are independent risk factors affecting the efficacy of the first 131I ablation after surgery for differentiated thyroid cancer.

Objective To compare the efficacy of radiofrequency ablation versus surgical resection in treatment of colorectal liver metastases with a maximum diameter ≤ 3 cm and a number ≤ 3, and to analyze the risk factors of recurrence. Methods The data of 97 patients with colorectal liver metastases from January 2012 to June 2016 treated at Tianjin Medical University Cancer Institute and Hospital were analyzed retrospectively. There were 66 males and 31 females. The patients were divided into the radiofre-quency ablation group (23 patients) and the surgical resection group ( 74 patients). The patients were followed up. The clinicopathological features of the two groups before treatment were compared. Kaplan-Meier curves were drawn, and the recurrence-free survival curve and overall survival curve of the two groups were compared by log-rank test. Univariate and multivariate Cox regression analysis was used to analyze the risk factors of recurrence. Results There were no significant differences in age, location of primary tumor, number and size of liver metastases, and preoperative carcinoembryonic antigen level between the two groups (P＞0. 05). On the date this study was censored, there were 50 patients who had developed recurrence in the surgical resection group and 22 patients in the ablation group, (67. 6% vs. 95. 7% ). The difference was significant (P＜0. 05). The 1-and 2-year recurrence-free survival rates were 54. 6% and 39. 0% in the surgical resection group and 39. 1% and 8. 7% in the radiofrequency ablation group, respectively. The difference was significant (P＜0. 05). There was no local recurrence in either of the two groups. There was no significant difference in the overall survival curves between the two groups (P＞0. 05). Univariate and multivariate analysis showed that N 1 ～2 staging (HR=1. 908, 95% CI: 1. 094～3. 325), simultaneous liver metastasis (HR=1. 662, 95% CI: 1. 024～2. 695) and radiofrequency ablation (HR=2. 708, 95% CI: 1. 589～4. 617) were independent risk factors of recurrence for colorectal liver metastasis. Conclusions Radiofrequency ablation can achieve complete ablation in patients with colorectal liver metastases with maximum diameter ≤3 cm and number≤3, but the recurrence rate of radiofrequency ablation is significantly higher than that of surgical resection. N 1 ～2 staging, simultaneous liver metastasis and radiofrequency ablation were independent risk factors for recurrence of colorectal liver metastasis.

Objective To compare the effects of propofol combined with fentanyl or dezocine on painless abortion and the influence on body movement.Methods From July 2016 to May 2017,240 patients with voluntary painless abortion who aged 19-45 years old in the Second People's Hospital of Linhai,were randomly divided into 3 groups according to the digital table ,with 80 cases in each group.D group was given propofol and dezocine ;F group was given propofol combined with fentanyl ;C group was the control group and was treated with propofol intravenous anesthesia,the three groups were given propofol added according to the specific situation.The operative time,recovery time and the total amount of propofol were compared among the three groups ;and the pain visual analogue scale (VAS) at 0min,15min,30min,1h,3h were comparedamong the three groups ;The incidence of respiratory depression and other adverse reactions were statistically analyzed in three groups.Results The operation time,recovery time,the total dosage of propofol in D group were (4.5 ±0.7)min,(1.2 ±0.3)min and (136.8 ±14.5)mg,respectively, which in F group were (4.6 ±0.8)min,(1.3 ±0.2)min and (139.6 ±12.1)mg,respectively,there were no statisti-cally significant differences between the two groups (all P＞0.05).The recovery time and total dosage of propofol in D group and F group were lower than those of C group [(2.4 ±0.6) min,(168.7 ±18.9) mg](t＝25.298,27.287, 11.977,27.287,all P＜0.05).The VAS scores at postoperative 0min,15min,30min,1h,3h in D group were lower than those in F group and group (t＝34.785,25.044,25.043,22.349,28.622,48.809,42.278,40.000,42.278, 40.000,all P＜0.05).The VAS scores at postoperative 0min,15min,30min,1h in F group were lower than those of C group(t＝36.978,24.406,19.846,24.406,all P ＜0.05).The incidence rates of nausea,sedentary,respiratory depression,hypotension in D group were 1.3%(1case),2.5%(2cases),1.3%(1case),0.0%(0cases), resperctively,which in F group were 0.0%(0cases),3.8%(3cases),3.8%(3cases),2.5%(2cases),which in D group,F group were lower than those in C group [6.3%(5cases),16.3%(13cases),11.3%(9cases),15.0%(12cases)](χ2＝3.925,3.657,3.925,3.657,5.889,3.152,3.152,3.657,all P＜0.05).Conclusion Propofol combined with dezocine and fentanyl used in painless abortion have good effect ,and the body movement is less ,but propofol combined with dezocine has less postoperative pain degree.

Objective To investigate the effect of electroacupuncture on acupoint local extracellular ionized atom concentrations under physiological status and provide a basis for exploring the mechanism of action of electroacupuncture. Method Twenty male SD rats were selected. Rat point Zusanli (ST36) was given electroacupuncture (1 mA, 0.2 ms and 2 Hz) for 60 min. Meanwhile, local tissue fluid was collected at point Zusanli and non-acupoints using a microdialyzer. The collection by molecular probe membrane sampling lasted 4 hrs: 60 min physiological status before electroacupuncture, 60 min electroacupuncture, 60 min after electroacupuncture and 120 min after electroacupuncture. Real-time analysis of the sample was made by electrolyte analysis to observe local changes in concentrations of Ca﹢﹢, K﹢, Na﹢and Cl- at point Zusanli. Result Local Ca﹢﹢concentrations at point Zusanli increased significantly during electroacupuncture (P=0.003, vs before electroacupuncture), rose gradually afterwards and reached the peak at 60 min after electroacupuncture (P=0.75, vs during electroacupuncture). Ca﹢﹢concentrations decreased at 120 min after electroacupuncture; there was a statistically significant difference comparedwith during electroacupuncture (P=0.04). Acupoint local extracellular concentrations of Na ﹢ and Cl- also increased significantly during electroacupuncture (P<0.001, P=0.007, vs before electroacupuncture) but decreased gradually during 60 min after electroacupuncture and to (71.81±15.09) mmol/L and (57.42±14.30) mmol/L, respectively, at 60 min after electroacupuncture (P=0.09, P=0.07 vs during electroacupuncture). Acupoint extracellular K ﹢concentrations had a tendency similar to those of Na﹢and Cl- but there was no statistically significant difference. Non-point electroacupuncture slightly increased extracellular concentrations of Ca﹢﹢, K﹢, Na﹢and Cl- but there were no statistically significant differences compared with before electroacupuncture (P>0.05). Conclusion Rat point Zusanli electroacupuncture can induce significant increases in acupoint local extracellular concentrations of Ca﹢﹢, K﹢, Na﹢and Cl- . Ionized atom concentrations decrease in different degrees after electroacupuncture. These provide an experimental basis for studying the physiological mechanism of electroacupuncture treatment.

Objective To determine the value of procalcitonin (PCT) as an early marker of postoperative infection after cardiac surgery with cardiopulmonary bypass (CPB).Methods A retrospective study was conducted. Patients with systemic inflammatory response syndrome (SIRS) after cardiac surgery with CPB admitted to intensive care unit (ICU) of Peking Union Medical College Hospital from November 2014 to January 2017 were enrolled. The cardiac surgery types and intraoperative conditions, the treatments in ICU, postoperative 28-day mortality and hospital mortality of the patients; the levels of plasma PCT measured at ICU admission, postoperative 1, 3, and 5 days were collected. According to whether patients with postoperative infection or not, they were divided into infection group and non-infection group. Receiver operating characteristic curve (ROC) was used to analyze the predictive value of plasma PCT levels at different time points in patients with infection.Results Eighty-two patients were included in this study, 25 (30.5％) had microbiological evidence of pneumonia. The levels of plasma PCT were increased with a peak 1 day after cardiac surgery in all patients, then significantly decreased 5 days after operation. Compared with patients without infection, the levels of plasma PCT were significantly increased in patients with infection at immediate and 1, 3, 5 days post operation in ICU [μg/L: 10.0 (6.0, 64.5) vs. 5.0 (1.0, 10.0), 31.0 (10.0, 116.2) vs. 5.0 (1.0, 10.0), 34.7 (10.0, 60.4) vs. 2.9 (0.7, 9.3), 15.8 (7.7, 29.4) vs. 0.7 (0.5, 2.6), allP < 0.01]. The area under the ROC curve (AUC) of the plasma PCT levels at ICU admission, and 1, 3, 5 days thereafter to predict infection for critically ill patients with SIRS after CPB was 0.77, 0.82, 0.86, and 0.91, respectively (allP < 0.01), cut-off values were 6.8, 9.4, 9.2 and 3.9μg/L, with the sensitivities of 76.0％, 84.0％, 79.2％, and 88.0％, and the specificities of 66.7％, 68.4％, 75.4％, and 78.9％, respectively.Conclusions In the presence of SIRS, elevated plasma PCT levels correlated with evidence of infection in early stage post operation in the ICU patients after cardiac surgery with use of CPB. The level of plasma PCT exceeded the cut-off value in different time points, suggesting infection, and it is helpful to predict the occurrence of infection early after operation.

OBJECTIVE:To provide reference for improving the reporting of adverse drug reactions (ADRs) in the hospital.METHODS:A questionnaire survey was conducted to investigate the reporting of ADRs and causes of missing reports by medical staff in all departments of a third grade class A hospital.The related data were statistically analyzed.RESULTS:A total of 967 questionnaires were distributed,and 900 questionnaires were collected,with a recovery rate of 93.07％.Among them,875 were valid questionnaires,and the effective rate was 97.22％.Among the medical staff,who can correctly answer the main causes of ADRs (drugs were toxic,individual difference),accounted for 42.51％ and 49.26％;35.89％ of staff did not receive any ADRs training in one year;33.83％ did not know the ADRs reporting system and ways;30.06％ would fill in the ADRs statement voluntarily;61.49％ considered that the absence of full-time personnel was the main difficulty in reporting ADRs;41.60％ indicated that they had previously reported ADRs.The causes of missing ADR reports by medical staff were ranked as high to low:uncertainty about ADRs,and there was no relevant information in the hospital (accounting for 45.94％);the filling process of ADR reports was complicated (accounting for 34.97％);do not have the phone number of ADR supervision department in hospital (accounting for 33.60％);do not know the reporting process (accounting for 33.49％),and so on.CONCLUSIONS:The situation of ADR reporting by medical staff in the hospital is not satisfactory,most of them have varying degrees of missing ADRs.The inadequate management and publicity of ADR monitoring,poorly trained by the hospital is an important reason for missing reporting.

Objective To explore the correlation of metabolic disorder of newly diagnosed type 2 metabolism(T2DM) and nonalcoholic fatty liver disease (NAFLD).Methods A total of 117 patients with newly diagnosed T2DM in Beijing Ditan Hospital Affiliated to Capital Medical University from June 2014 to June 2015 were enrolled.Patients were divided into two groups:T2DM with NAFLD of 57 cases and T2DM without NAFLD of 60 cases.Body mass index (BMI),waist circumference (WC),liver and kidney function,serum lipid,glycosylated hemoglobin A1c (HbA1c),fasting glucose,fasting insulin and C-peptide (FCP) were detected.The insulin resistance and β-cell function were assessed by homeostasis model assessment insulin resistance (HOMA-IR) and HOMA-β.Results The incidence of NAFLD in T2DM patients was 51％ (that was,60 cases of T2DM patients with NAFLD),compared with 2TDM group,the metabolic index of T2DM without NAFLD was significantly increased (blood triglyceride (TG):(2.58 + 1.8) mmol/1 vs.(1.22 + 0.4) mmol/l,fasting blood glucose:(11.5+6.1) mmol/l vs.(9.2+4.3) mmol/l,serum uric acid:(465.3+65) umol/l vs.(325.3+72) umoL/l;P =0.03,0.03,0.02);HOMA-IR was more serious ((4.9 ± 2.8) vs.(3.8 ± 2.7);P =0.03);insulin β-cell function was compensatory more obvious ((49.2 ± 27) vs.(29.5 ± 18);P =0.02);prevalence rate of obesity,hypertension and diabetic ketoacidosis (DKD),diabetic retinopathy (DR),diabetic peripheral neuropathy(DPN) were significantly increased(P＜0.05).Logistic regression analysis showed that,smoking(OR=1.405,95％CI:1.262-1.567),male(OR=1.037,95％CI:1.015-1.063),BMI(OR=1.113,95％CI:1.278-2.531),WC (OR =1.624,95％ CI:1.162-1.761) and TG (OR =1.823,95％ CI:1.2822.563) were risk factors of NAFLD (P ＜ 0.05).Conclusion T2DM patients with NAFLD have severer insulin resistance than those without NAFLD.The β-cell function of those patients is compensatory increased.NAFLD prevalence rate significantly increase in patients with obesity,especially in male diabetic patients who smoking.

Objective To evaluate the endothelium-dependent vasodilation in children after repair for coarctation of aota (CoA). Methods A group of 20 children having undergone CoA repair between January 2010 and October 2010 in Guangzhou Women and Children′s Medical Center were include in the study , including 12 infants aged less than 6 months and 8 ones aged more than 6 months. Another 20 healthy children were enrolled during the same period as controls. All the subjects underwent monitoring of resting blood pressure and flow-mediated dilation (FMD) of the brachial artery in 4-year follow-up. Results There were no resting hypertension in all subjects , but FMD in the CoA group was higher than in the control group and so it was with the early surgery group and non early surgery group. Conclusion The surgical repair for coarctation of aorta could not cure the vascular function impairment satisfactorily , neither is the early surgery effective in alleviating the injuries in vascular endothelia.
