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.

The Pituitary Society released the 2023 International Consensus on the Diagnosis and Treatment of Prolactin-Secreting Adenomas, marking another update following the guidelines from the Endocrine Society in 2006 and 2011. Published in Nature Reviews Endocrinology, this consensus is based on the latest research evidence in recent years, covering topics such as the efficacy, long-term adverse effects, and withdrawal protocols of dopamine receptor agonists, as well as indications for surgery, preoperative medical therapy, and radiation therapy. It comprehensively discusses the treatment of prolactin-secreting adenomas in special periods and conditions. This article provides a detailed interpretation of the core recommended points in the consensus, focusing on four major aspects: diagnosis, treatment, special populations, and rare conditions of prolactinoma, aiming to help clinicians gain a comprehensive understanding of the consensus and provide assistance in clinical management.

Objective:To investigate the incidence and prothrombotic risk factors of postoperative venous thromboembolism(VTE) in Cushing′s disease and to further develop an assessment model to identify those at high risk of postoperative VTE events.Methods:A retrospective study was performed in 82 patients who were admitted to Huashan Hospital, Fudan University during January 2019 and January 2020 and diagnosed with Cushing′s disease. These patients underwent the evaluation about their clinical, hormonal, and coagulation parameters, as well as ultrasonography and pulmonary angio-CT when necessary. The least absolute shrinkage and selection operator(LASSO) regression analysis was used to screen independent risk factors, and a nomogram model for postsurgical VTE risk assessment in Cushing′s disease was initially established, and Bootstrap method was used for internal verification. Finally, the predictive model was evaluated for calibration and clinical applicability in the study cohort.Results:Nineteen patients(23.17%) developed VTE events, with 14 cases occurring after endoscopic transsphenoidal surgery. Compared to patients without VTE, those in the VTE group were older( P<0.001), had longer postoperative bed rest, higher rates of current infection, higher HbA 1C levels, and more severe glucose tolerance impairment(all P<0.05). Through LASSO regression analysis, two independent risk factors for postoperative VTE were identified: Age and current infection. Then a VTE risk assessment nomogram model was established to predict the patients at high risk of VTE. In the nomogram model for VTE risk assessment, the area under the receiver operating characteristic curve was 0.868(95% CI 0.787-0.949), with the calibration curve closely aligning with the ideal diagonal line and the clinical decision curve exceeding the two extreme curves. Conclusions:Advanced perioperative assessment needs to be taken to screen those with high VTE risks in patients diagnosed with Cushing′s disease. Additionally, during the perioperative period, patients with Cushing′s disease should undergo mandatory physical activity or prophylactic anticoagulant therapy.

Objective:To understand the incidence and clinical characteristics of dopamine agonist(DA) therapy-related impulse control disorders(ICDs) in prolactinoma patients.Methods:Outpatients diagnosed with prolactinoma from the Department of Endocrinology in Huashan Hospital from December 2019 to June 2020 were consecutively included and clinical data were collected. Impulse control disorders were screened with Questionnaire for Impulsive-Compulsive Disorders in Parkinson′s Disease(QUIP). Barratt Impulsiveness Scale 11(BIS-11) was used to evaluate personality construct of impulsiveness from three sub-factors . Health related quality of life was evaluated by the MOS 36-Item Short Form Health Survey(SF-36).Results:Among the 111 cases included, 40 were male and 53 were female, with an average age of(34.74±9.05) years and an average disease duration of(66.69±50.70) months. The initial prolactin level was 147.25(89.97, 470) ng/mL and the percentage of macroadenoma was 46.8%. Ninety cases received DA while 21 cases didn′t. According to the QUIP, any ICD was screened positive in 22 cases(24.7%) in the DA group and 3 cases(14.3%) in the untreated group. The attention impulsiveness scores of BIS-11 in the DA group were higher than the untreated group(23.32±3.67 vs 21.71±2.55, P=0.022). Among the ICDs positive cases in the DA group, the most common disorders were pathological gambling(40.6%) and hypersexuality(40.6%). Compared with the negative group, the non-planning impulsiveness scores of BIS-11 in the positive group were higher, while the scores of social function(69.32±24.62 vs 83.08±17.11, P=0.021), role emotional(50.00±45.72 vs 71.10±40.68, P=0.043) and mental health(55.27±22.75 vs 64.59±17.53, P=0.048) in SF-36 scale were lower in the positive group. Besides, the percentage of male(68.2% vs 38.2%, P=0.014) and initial prolactin level[470.00(130.00, 3 770.00) vs 140.29(79.50, 465.59) ng/mL, P=0.028] in the positive group were higher. Male was an independent risk factor of the presence of ICDs( OR=3.46, 95% CI 1.24-9.61, P=0.017). No significant difference was found in the type of drugs, duration, maximal or cumulative dose of treatment with DA between the two groups. Conclusion:Impulse control disorders may occur in prolactinoma patients receiving DA treatment and affect the quality of life. Endocrinologists should screen impulse control disorders in this patient set.

Objective:To analyze the causes and influencing factors of conversion from laparoscopic surgery to laparotomy.Methods:To analyze and summarize the clinical data of 84 patients who converted to laparotomy in 16 203 cases of laparoscopic surgery from August 2017 to August 2020 in the Department of Gynecology of the Affiliated Hospital of Qingdao University, each patient converted to surgery was matched with 2 patients who underwent simple laparoscopic surgery. The patients were divided into conversion to laparotomy group (84 cases) and control group (168) cases, and analyze the influencing factors of laparoscopic conversion to laparotomy. χ 2 test or corrected χ 2 test or Fisher exact probability method were used for the comparison of counting data between groups, and conditional regression analysis was used for the multivariate analysis of case control design. Results:The conversion rate of gynecologic laparoscopic surgery to laparotomy was 0.52%(84/16 203). The reasons for 84 cases of conversion from laparoscopic surgery to open surgery were as follows: pelvic adhesion 50.0%(42/84), unexpected malignant tumor 19.0%(16/84), tumor oversize or special shape and location 14.3%(12/84), hemostasis difficulty 7.1%(6/84), multiple uterine fibroids 3.5%(3/84), simultaneous surgery 3.5%(3/84), bladder injury 1.2%(1/84), and subcutaneous emphysema 1.2%(1/84) during the operation. There were no significant differences in body mass index and comorbidities (diabetes, hypertension, coronary heart disease, thyroid disease) between the two groups (all P>0.05). And the history of endometriosis was 36.9% (31/84) and the history of pelvic surgery in the transperitoneal group was 60.7% (51/84) higher than that in the conversion to laparotomy group of 20.8% (35/84), 30.6% (51/84) (χ 2=7.482, 21.42, P=0.006). The results of conditional regression analysis showed that that surgical history( OR=3.979, 95% CI 2.010-7.874, P<0.001 and thyroid history ( OR=15.333, 95% CI 1.087-216.346, P=0.005) increased the risk of conversion to laparotomy; Hypertension history ( OR=0.203, 95% CI 0.067-0.622, P=0.005) reduced the risk of conversion to laparotomy. Further analysis of which operation type affected the conversion to laparotomy showed that cesarean section ( OR=2.105, 95% CI 1.109-4.351, P=0.044), myomectomy ( OR=11.605, 95% CI 3.306-40.735, P<0.001), and ovarian cyst removal ( OR=7.914, 95% CI 2.157-21.037, P=0.002) affected the conversion to laparotomy. Conclusion:The main reason for conversion from gynecologic laparoscopic surgery to laparotomy is pelvic adhesion. The history of surgery and thyroid disease are the risk factors for conversion to laparotomy. Among them, myomectomy and ovarian cyst removal are important factors for conversion to laparotomy. Before operation, appropriate clinical operation methods should be selected according to the patient's medical history and condition to ensure the patient's safety.

Objective:To describe the prevalence and clinical characteristics of macroprolactinemia in hyperprolactinemia patients.Methods:Consecutive 111 outpatients diagnosed with hyperprolactinemia were included in this study. Macroprolactin was routinely screened using the polyethylene glycol(PEG) precipitation method. Recovery of monomeric prolactin less than 40% was defined as macroprolactinemia. Clinical characteristics were analyzed in this study.Results:Among the 111 cases included, 99 were female and 12 were male, with an average age of(32.2±7.9) years. There were 32 cases(28.8%) of macroprolactinemia and 28 of them with normal monomeric prolactin levels(simple macroprolactinemia). prolactin levels before precipitation in simple macroprolactinemia were significantly lower than those with true hyperprolactinemia[(49.81±23.58 vs 83.56±65.82) ng/mL, P<0.05]. No amenorrhea and infertility were observed in patients with simple macroprolactinemia. The clinical manifestations of prolonged menstruation, oligomenorrhea and galactorrhea in female patients accounted for 25.9%, 37.0%, and 7.4%, respectively. Imaging data were obtained in 92 cases. The prevalence of pituitary adenomas in simple macroprolactinemia and true hyperprolactinemia was 42.9% and 66.0%, respectively. Fifteen(46.8%) of the macroprolactinemia cases were receiving or had received bromocriptine treatment, and 66.7% of them failed to achieve normal prolactin levels during therapy. Conclusion:Macroprolactinemia might be common in clinical practice. Macroprolactin should be screened in hyperprolactinemia patients lack of amenorrhea and infertility, and with poor response to dopamine agonist therapy.

Objective:To evaluate the volume status of hemodialysis patients with hypertension by bioelectrical impedance vector analysis, and investigate the effect of high volume status on the prognosis of patients with hypertension.Methods:The study subjects came from the patients with pre-dialysis systolic blood pressure>160 mmHg (mean systolic blood pressure of 6 times of treatment) in the Affiliated BenQ Hospital of Nanjing Medical University. According to the volume status assessed by bioelectrical impedance vector analysis, patients were divided into two groups: fluid overload group and non-overload group (including normal fluid status and fluid decline). The clinical data, laboratory test results, ratio of intracellular and extracellular water (ICW and ECW), body cell mass, lean body mass and the percentage of total body weight, fat percentage of body weight, resistance/height, reactance/height, phase angle and illmarker were compared between two groups. Kaplan-Meier survival curve was used to compare the difference of survival rate between the two groups.Results:A total of 51 hemodialysis patients with hypertension were enrolled in this study, including 19 patients in fluid overload group and 32 patients in non-overload group (27 patients with normal volume status and 5 patients with decreased volume). The levels of albumin, prealbumin, hemoglobin, hematocrit and serum phosphorus in patients with fluid overload decreased significantly compared with non-overload patients (all P<0.05), and the proportion of lymphocytes increased in fluid-overload patients ( P<0.05). The ratio of extracellular water and illmarker index in fluid overload group were significantly higher than those in the other group (both P<0.01). However, phase angle, resistance/height, reactance/height were lower than those in patients with non-overload (all P<0.01). After 20 months of clinical observation, the control rate of blood pressure (pre-dialysis systolic blood pressure<160 mmHg) in fluid overload group was lower than that in the non-overload group (26.3% vs 43.8%), but not statistically significant ( P=0.218). The all-cause mortality rate of patients in the fluid overload group was higher than non-overload group (26.3% vs 15.6%). Kaplan-Meier survival curve analysis suggested that the difference in survival rate between the two groups was not statistically significant. Conclusions:The extracellular fluid of hemodialysis patients with hypertension and fluid overload increases significantly, and the nutritional status evaluation index decreases compared with that of patients without increased volume. Increased proportion of lymphocytes may be related to the micro-inflammatory status. Blood pressure is more difficult to control in hypertensive patients with fluid overload and the clinical prognosis can be worse in patients without increased volume.

Objective To evaluate the effect of dexmedetomidine on pulmonary function in elderly patients with mild obstructive ventilatory dysfunction under protective ventilation during laparoseopic gallbladder surgery. Methods Sixty patients were included who underwent laparoseopic gallbladder surgery with general anesthesia. For the all subjects, the age ranged from 65 to 75 years old, the body mass index range was 18.5～23.9 kg/m2, and the ASA grade wasⅡorⅢ. In the subject selection, the gender was not limited, and the included subjects were diagnosed with mild obstructive ventilation dysfunction by preoperative pulmonary function tests. All the subjects were randomly divided into 2 groups (n=30), including dexmedetomidine group (group D) and control group (group C). In the group D, dexmedetomidine was intravenously infused at a dose of 1 μg/kg 10 min before and after the general anesthesia induction, and at a rate of 0.4μg/(kg·h) after tracheal intubation until the end of operation. Group C was given an equal volume of normal saline. Airway peak pressure (Ppeak), mean airway pressure (Pmean), airway plateau pressure (Pplat), and positive end-expiratory pressure (PEEP) were measured at 5 min after intubation (before pneumoperitoneum) (T1), end of pneumoperjtoneum (T2), and 10 min after the end of pneumoperitoneum (T3). The driving pressure (DP) was calculated. The blood samples of the radial artery were collected for blood gas analysis, and PaO2 and PaCO2 were recorded. The oxygenation index (PaO2/FiO2), respiratory index (RI), dead space ventilation rate (VD/VT), and alveolar-arterial oxygen partial pressure difference (A-aDO2) were calculated. The time of removal of the tracheal tube and the occurrences of complications such as hypercapnia and hypoxemia within 48 hours after extubation were recorded. Results Compared with group C, Ppeak, Pmean, DP, RI, VD/VT and A-aDO2 at T1, T2, T3 were decreased in group D, PaO2/FiO2 was increased, postoperative extubation time was shortened, and the incidence of hypoxemia was reduced within 48 h after operation (P<0.05). Compared with T1, Ppeak, Pmean, DP, RI, VD/VT and A-aDO2 at T2 were increased, and PaO2/FiO2 was decreased(P<0.05). Conclusions Dexmedetomidine can improve the pulmonary function in elderly patients with mild obstructive ventilatory dysfunction under protective ventilation during laparoseopic gallbladder surgery.

Objective: To investigate the clinical value of the serum new molecular markers, soluble triggering receptor expressed on myeloid cells-1(sTREM-1)and soluble hemoglobin scavenger receptor(sCD163), in the diagnosis of sepsis in elderly patients with burns. Methods: A total of 58 inpatients with burns from Jun 2017 to June 2018 were enrolled in the study.Patients were divided into three groups: the sepsis group(n=12), the localized infection group(n=21)and the non-infection group(n=29). The levels of sTREM-1 and sCD163 were determined by enzyme-linked immunosorbent assays(ELISAs). The clinical diagnostic value of sTREM-1 and sCD163 was assessed by receiver operating characteristic(ROC)curve analysis. Results: There was a statistically significant difference in the levels of sTREM-1 and sCD163 at day 1 between the three groups(F=20.994 and 38.363, P<0.01). Serum levels of sTREM-1 and sCD163 were higher in the sepsis group than in the localized infection group and the non-infection group.Serum levels of sTREM-1 and sCD163 were higher in the localized infection group than in the non-infection group.Serum levels of sTREM-1 and sCD163 were lower at day 7 than those at day 1 in all groups(F=21.242 and 41.035, P<0.01). Serum sTREM-1 levels were positively correlated with serum sCD163 levels(r=0.609, P=0.000). The AUC of sTREM-1 and sCD163 for the diagnosis of sepsis was 0.880(95%CI: 0.816~0.926). Conclusions Serum levels of sTREM-1 and sCD163 are elevated with increasing degrees of infection.Monitoring serum sTREM-1 and sCD163 levels is helpful for the diagnosis of sepsis in elderly patients with burns.
