Refractory prolactinoma is the most common pituitary neuroendocrine tumor.Dopamine receptor agonists(DA)are the primary choice for drug treatment.Most patients with prolactinomas respond well to DA.However,a minority of prolactinomas patients still show resistance to DA.Although drug-resistant and refractory prolactinomas are rare in clinical practice,their treatment is extremely challenging.Even a combination of drug therapy,multiple surgeries,and radiotherapy may not yield satisfactory outcomes.Therefore,standardizing the diagnosis and treatment process and pathway for refractory prolactionmas and exploring more effective multidisciplinary collaborative treatment strategies are urgent problems to be solved.In the clinical management of refractory prolactinomas,it is often necessary to consider the patient's condition comprehensively,replace other types of DA,or consider surgery,radiotherapy,and immunotherapy,which requires multidisciplinary diagnosis and treatment.This review synthesizes the latest literature at home and abroad to systematically discuss the latest advances in drug therapy,surgery,and radiotherapy treatments for refractory prolactionmas,aiming to provide new ideas for basic research,clinical diagnosis and treatment.

Objective To compare the effects of different dose prediction models of sufentanil in elderly hip arthroplasty with ultrasound-guided bow tie fascia iliac block.Methods A total of 90 elderly patients who underwent ultrasound-guided bow tie fascia iliac during hip arthroplasty in our hospital from June 2018 to June 2022 were selected.The dose of sufentanil was determined by a linear regression(ALR),multiple linear regression(MLR)or deep belief networks(DBN).Patients were randomly divided into the ALR group,the MLR group and the DBN group,with 30 cases in each group.The analgesic effect,hemodynamic index,inflammatory factor level and surgical index were compared among all groups.Kaplan-Meier method was used to analyze the incidence of hip infection 2 weeks after surgery in each group.Results There was no significant difference in the gender,age,body weight,American Society of Anesthesiologists(ASA)classification or complications among all groups(P>0.05).The Harris score 24 hours after surgery and duration of sensory block in the DBN group were higher/longer than those in the ALR group,numerical rating scale(NRS)score 24 hours after surgery,mean arterial pressure(MAP)and heart rate(HR)at the beginning of surgery and 30 minutes after surgery,levels of interleukin-17(IL-17)and tumor necrosis factor-α(TNF-α)24 hours after surgery,onset time of sensory block,and number of patient controlled analgesia(PCA)compression were lower/earlier/less than those in the ALR group,the modified observer's assessment of alertness/sedation scale(OAA/S)score 24 hours after surgery was significantly lower than those in the ALR group and the MLR group,with statistically significant differences(P<0.05).Harris score 24 hours after surgery and duration of sensory block in the MLR group were higher/longer than those in the ALR group,modified OAA/S score 12 hours after surgery,MAP 30 minutes after surgery,levels of IL-17 and TNF-α 24 hours after surgery,onset time of sensory block,and the number of PCA compressions were lower/longer/less than those in the ALR group,with statistically significant differences(P<0.05).Kaplan-Meier analysis showed that there were significant differences in the incidences of hip infection 2 weeks after surgery among all groups(P<0.05),and there were significant differences in the incidences of hip infection 2 weeks after surgery between the ALR group and the DBN group(P<0.05).Conclusion The effectiveness of calculating the dose of sufentanil using the MLR and DBN in elderly hip arthroplasty with bow tie fascia iliac block is better than that of ALR,and the advantage of DBN is more obvious.

Objective     To investigate the perioperative clinical effects and follow-up results of minimally invasive coronary artery bypass grafting (MICS CABG) versus conventional coronary artery bypass grafting (CABG) in thoracotomy. Methods     The patients who received off-pump CABG in Beijing Anzhen Hospital from January 2017 to October 2021 were collected. Among them, the patients receiving MICS CABG performed by the same surgeon were divided into a minimally invasive group, and the patients receiving median thoracotomy were into a conventional group. By propensity score matching, preoperative data were balanced. Perioperative and postoperative follow-up data of the two groups were compared. Results     A total of 890 patients were collected. There were 211 males and 28 females, aged 60.54±9.40 years in the minimally invasive group, and 487 males and 164 females, aged 62.31±8.64 years in the conventional group. After propensity score matching, there were 239 patients in each group. Compared with the conventional group, patients in the minimally invasive group had longer operation time, shorter drainage duration, less drainage volume on the first postoperative day, shorter postoperative hospital stay, and lower rate of positive inotropenic drugs use, while there was no statistical difference in the mean number of bypass grafts, ICU stay, ventilator-assisted time, blood transfusion rate or perioperative complications (P>0.05). During the median follow-up of 2.25 years, there was no statistical difference in major adverse cardiovascular and cerebrovascular events, including all-cause death, stroke or revascularization between the two groups (P>0.05). Conclusion    Reasonable clinical strategies can ensure perioperative and mid-term surgical outcomes of MICS CABG not inferior to conventional CABG. In addition, MICS CABG has the advantages in terms of postoperative hospital stay, postoperative drainage volume, and rate of positive inotropic drugs use.

Traditional Chinese medicine(TCM) compound preparations have complex compositions. As a widely used TCM injection, Shuganning Injection, its in vivo processes are not yet fully understood. Determining the plasma protein binding rate is of great significance for pharmacokinetic and pharmacodynamic studies. In this experiment, the equilibrium dialysis method combined with UPLC-MS/MS technology was used to determine the plasma protein binding rates of 10 components, including p-hydroxyacetophenone, caffeic acid, baicalein, oroxylin A, geniposide, baicalin, cynaroside, oroxylin A-7-O-β-D-glucuronide, scutellarin, and hyperoside, in Shuganning Injection in rat and human plasma to provide a theoretical basis for further elucidating the in vivo processes of Shuganning Injection and guiding clinical medication. The results showed that, except for baicalein and geniposide, the plasma protein binding rates of the other eight components were higher in human plasma than in rat plasma, and there were interspecies differences. In human plasma, except for geniposide, caffeic acid, and baicalin, the plasma protein binding rates of the remaining seven components were above 80%, with baicalein and oroxylin A exceeding 90%. All components exhibit a high level of binding to plasma proteins, with the exception of geniposide.

OBJECTIVE: To investigate the feasibility of using thyroid ^99mTcO₄^- imaging ROI ratio instead of 24 h radioactive iodine uptake (RAIU) for estimating ¹³¹I dose in individualized treatment of hyperthyroidism. METHODS: We retrospectively analyzed the clinical data of 132 patients receiving ¹³¹I treatment in our department between January and June, 2019. According to their 3 h/24 h RAIU peak ratio, the patients were divided into peak forward (≥80%) group and no peak forward (< 80%) group. In the former group, the therapeutic ¹³¹I dose was calculated based the Marinelli formula (¹³¹I dose=thyroid mass×planned amount/24 h RAIU), and in the latter group, the correlation between the ROI ratio and the 24 h RAIU was analyzed, and the ¹³¹I dose was calculated using a modified Marinelli formula where 24 h RAIU was replaced by a converted ROI ratio. The two groups of patients were compared for antithyroid drug type and discontinuation time, thyroid hormones and related antibodies, thyroid area, thyroid mass and ¹³¹I dose. All the patients were and followed up for one year to analyze the treatment efficacy. The ROI ratios after the treatment were analyzed in the two groups using ROC curves. RESULTS: There was a significant positive correlation between the ROI ratio and 24 h RAUI in the no peak forward group (Y=58.13 + 0.2X, R²=0.118, P < 0.05), and the formula for calculating ¹³¹I dose was converted into: ¹³¹I dose=thyroid mass× planned amount/(58.13+0.2×ROI ratio)%. Before the treatment, therapeutic ¹³¹I dose, thyroid hormone levels, TRAb, 3 h and 24 h RAIU, thyroid area, thyroid mass, and ROI ratio all differed significantly between the two groups (P < 0.05). At 3 months after treatment, thyroid hormone levels, TRAb, TPOAb, thyroid area, thyroid mass, ROI ratio, response rate, hypothyroidism rate, cure rate, remission rate, and nonresponse rate were similar between two groups (P>0.05). At the 1-year follow-up, the composition ratios of hyperthyroidism, hypothyroidism and cured cases remained similar between two groups (P>0.05). ROC curve analysis showed that at 3 months after treatment, the optimal cutoff values of ROI ratio for predicting hyperthyroid recurrence and hypothyroidism were 15.79 and 6.33, respectively. CONCLUSION Thyroid ^99mTcO₄^- imaging ROI ratio can be used for calculating ¹³¹I dose in individualized treatment of hyperthyroidism and for prognostic evaluation of the patients.

Objective     To compare the mid- and long-term efficacy of minimally invasive coronary artery bypass grafting (MICS) versus conventional coronary artery bypass grafting (CABG). Methods     This study analyzed 679 patients with coronary heart disease treated in the Minimally Invasive Heart Center of Beijing Anzhen Hospital from 2015 to 2019, including 532 males and 147 females with an average age of 61.16 years. A total of 281 patients underwent MICS (a MICS group) and 398 patients underwent conventional CABG (a CABG group). The clinical data of the patients in the two groups were analyzed. Results    The average operation time was longer (P<0.001), the total hospital stay was shorter (P<0.001), and the amount of drainage 24 h after the operation was less (P=0.029) in the MICS group. There was no statistical difference in the incidence of perioperative complications between the two groups. The median follow-up time was 2.68 years. The follow-up results showed that the total incidence of cumulative main adverse cardiovascular and cerebrovascular events in the CABG group was higher at 2 years (6.2% vs. 3.8%) and 4 years (9.3% vs. 7.6%), but the difference was not statistically significant (P>0.05). There was no statistical difference in 2- or 4-year all-cause death between the two groups (3.5% vs. 2.8%, 5.6% vs. 2.8%, P>0.05). At the same time, there was no statistical difference in the incidence of myocardial infarction, stroke or revascularization between the two groups (P>0.05). Conclusion    Compared with conventional CABG, MICS can achieve satisfactory mid- and long-term outcomes.

Objective: To analyze the clinical characteristics, laboratory examination, diagnosis, treatment, and outcome of hereditary factor Ⅹ (FⅩ) deficiency. Methods: Clinical data of 11 patients with congenital FⅩ deficiency were retrospectively analyzed from July 2009 to February 2021. Results: There were 3 males and 8 females. Median age was 39 (5-55) years. The media duration of follow-up was 81.67 (1.87-142.73) months. Of the 11 patients, 10 had bleeding symptoms, 7 had ecchymosis or hemorrhage after skin bump, 7 had nosebleed, 6 had gingival hemorrhage, and 1 had muscle hematoma. Among the female patients, 6 had menorrhagia and 1 experienced bleeding after vaginal delivery. Family history of FⅩ deficiency was found in one case. Eight patients had a history of surgery, and four had postoperative bleeding. Laboratory findings were characterized by significantly prolonged activated partial thromboplastin time, prothrombin time, and decreased FⅩ activity (FⅩ∶C) . Four cases underwent gene mutation analysis and five new mutations were found. Four cases were treated with prothrombin complex concentrates (PCC) and seven cases with fresh frozen plasma (FFP) . One female patient had significantly reduced menstrual volume after PCC prophylactic therapy. One patient received FFP for prophylactic infusion with no bleeding during and after the operation. Conclusion: Most patients with congenital FⅩ deficiency had bleeding symptoms and there was no significant correlation between severity of bleeding symptoms and FⅩ∶C. Prophylaxis should be applied in patients with severe bleeding tendencies. Gene mutation test is significant for screening, diagnosis, and prognosis prediction of congenital FX deficiency.

OBJECTIVES: To investigate the clinical treatment outcomes and the changes of the outcomes over time in extremely preterm twins in Guangdong Province, China. METHODS: A retrospective analysis was performed for 269 pairs of extremely preterm twins with a gestational age of <28 weeks who were admitted to the department of neonatology in 26 grade A tertiary hospitals in Guangdong Province from January 2008 to December 2017. According to the admission time, they were divided into two groups: 2008-2012 and 2013-2017. Besides, each pair of twins was divided into the heavier infant and the lighter infant subgroups according to birth weight. The perinatal data of mothers and hospitalization data of neonates were collected. The survival rate of twins and the incidence rate of complications were compared between the 2008-2012 and 2013-2017 groups. RESULTS: Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of severe asphyxia and smaller head circumference at birth (P<0.05). The mortality rates of both of the twins, the heavier infant of the twins, and the lighter infant of the twins were lower in the 2013-2017 group compared with the 2008-2012 group (P<0.05). Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of pulmonary hemorrhage, patent ductus arteriosus (PDA), periventricular-intraventricular hemorrhage (P-IVH), and neonatal respiratory distress syndrome (NRDS) and a higher incidence rate of bronchopulmonary dysplasia (P<0.05). CONCLUSIONS There is a significant increase in the survival rate over time in extremely preterm twins with a gestational age of <28 weeks in the 26 grade A tertiary hospitals in Guangdong Province. The incidences of severe asphyxia, pulmonary hemorrhage, PDA, P-IVH, and NRDS decrease in both the heavier and lighter infants of the twins, but the incidence of bronchopulmonary dysplasia increases. With the improvement of diagnosis and treatment, the multidisciplinary collaboration between different fields of fetal medicine including prenatal diagnosis, obstetrics, and neonatology is needed in the future to jointly develop management strategies for twin pregnancy.

Objective:To compare the perioperative outcomes and short-term graft patency between patients who underwent multivessel off-pump coronary artery bypass graft(OPCABG) via left intercoastal space or sternotomy.Methods:Between January 2017 and August 2019, 100 patients who underwent minimal invasive coronary artery bypass graft(MICS CABG) were compared with 235 patients who underwent OPCABG by single surgeon at our institute. Among them, 257 cases were male and 78 were female, aged 34 to 84 years, with mean age(61.35±8.79)years old. Due to important differences in patients’ characteristics, a propensity score-matched analysis based on 12 covariates was performed to match in a 1∶2 fashion. 82 patients(MICS group) were matched with 127 patients(OPCABG group). Surgical and postoperative outcomes were evaluated.Results:There was no statistical difference of perioperative mortality, myocardial infarction, and stroke rate( P>0.05). In MICS group, use of internal thoracic artery was higher and conversion to cardiopulmonary bypass was lower( P<0.05), but reoperation, new onset atrial fibrillation , and the use of mechanical device were similar( P>0.05). In addition, operation duration was longer but transfusion rate, postoperative chest tube drainage within 24 hours and postoperative hospital stays were less in the MICS group( P<0.05). LIMA, vein and overall graft patency were similar in the two groups shown by postoperative one-year CTA( P>0.05). Conclusion:MICS CABG is safe and feasible for patients with multiple coronary lesions. It has similar in-hospital outcomes and short-term graft patency but less transfusion and faster recovery compared to conventional OPCABG via sternotomy.

OBJECTIVE: The individual cascades of the insulin-like growth factor-1 (IGF-1) signaling pathway and the molecular mechanism of aging have not been fully clarified. In the current study, we explored the effect of DNA polymerase delta 1 (POLD1) on the IGF-1 signaling pathway in cell aging. METHODS: First, we analyzed the relationship between IGF-1 and POLD1 expression in aging. To investigate the effect of IGF-1 on POLD1 expression and aging, the 2BS cells were incubated with young-age or old-age human serum, IGF-1 protein, or linsitinib. Next, the effect of IGF-1 on aging was examined in the 2BS cells with increased or decreased POLD1 expression to clarify the molecular mechanism. RESULTS: In this study, we found that IGF-1 expression increased and POLD1 expression decreased with aging in human serum and hippocampal tissues of SAMP8 mice, and a negative relationship between IGF-1 and POLD1 expression was observed. Furthermore, the cells cultured with old-age human serum or IGF-1 showed lower POLD1 expression and more pronounced senescence characteristics, and the effect could be reversed by treatment with linsitinib or overexpression of POLD1, while the effect of linsitinib on cell aging could be reversed with the knockdown of POLD1. CONCLUSION Taken collectively, our findings demonstrate that IGF-1 promotes aging by binding to IGF-1R and inhibiting the expression of POLD1. These findings offer a new target for anti-aging strategies.
