This article reports the diagnosis and treatment of a case of acromegaly in a pregnant patient who took bromocriptine during pregnancy and delivered successfully. A retrospective summary of the clinical data and treatment outcomes before and after two pregnancies of the patient is provided. The patient took bromocriptine during the second pregnancy, and her condition remained stable. A baby girl was delivered by caesarean section at full term. The article suggests that pregnancy in acromegaly patients, after the stabilization of the condition, can lead to favorable outcomes. The use of dopamine receptor agonists during pregnancy does not increase adverse events during the perinatal period.

Objective:To analyze the clinical characteristics and endoscopic surgical procedures of the second branchial cleft cyst type Ⅳ in children.Methods:A retrospective review was conducted on 15 pediatric cases with type Ⅳ second branchial cleft cysts treated at the Beijing Children′s Hospital affiliated with Capital Medical University and Henan Children′s Hospital from September 2019 to November 2023. All patients underwent excision via a two-person, three-hand endoscopic transoral approach. The cohort included 12 males and 3 females, with an age range of 10 months to 10 years and 5 months, and a median age of (59.20±32.05) months. The clinical data of initial symptoms, sides, imaging features, treatment methods, complications, length of hospital stay, prognosis and outcome were recorded and analyzed. SPSS 22.0 software was used for statistical analysis.Results:Of the 15 children, 13 cases presented with snoring as the primary symptom, 1 case with dysphagia, and 1 case was asymptomatic and was found unintentionally. The mean disease duration was (6.74±9.05) months (range, from 3 days-2 years). MRI revealed cystic lesions on the right side in 12 cases and on the left side in 3 cases, characterized by uniform long T2 signal, equal T1 or short T1 signal. The cysts appeared dumbbell-shaped in 10 cases with the pharyngeal constrictor muscle as the waist, the posterior outside of the mass was adjacent to the internal carotid artery. The remaining 5 cases showed an isolated cyst located inside the pharyngeal constrictor muscle. The intraoperative MRI findings were consistent. Partial cystectomy was performed in 10 cases near the internal carotid artery, leaving only the portion with a clear arterial pulse intact. Five cases with isolated cysts on the medial side of the pharyngeal constrictor muscle were totally removed. The average length of hospital stay was (4.53±0.52) days (4-5 days). All patients were followed up for 7-56 months [median (30±15.12) months] with no recurrence of symptoms observed.Conclusions:The second branchial cleft cyst type Ⅳ in children is characterized by prominent pharyngeal cystic mass, with snoring as a predominant initial symptom, MRI provides excellent diagnostic value. The two-person, third-hand endoscopic transoral approach for cyst excision is feasible, safe, and offers the benefits of minimal invasiveness and reduced hospitalization time.

Injury monitoring is an important approach for injury control and is an important part of comprehensive disease monitoring. With the development of medical digitalization, an intelligent injury monitoring system has been created in Yinzhou District, Ningbo City, Zhejiang Province using artificial intelligence techniques based on Ningbo Municipal Health Information Platform and has been applied across the district since 2019. The manual card-reporting mode has been transformed to intelligent card-reporting mode in this system, which achieves functions of epidemiological analyses of the monitoring data, early warning of high-incidence injuries, classified management of injury and quality control of report cards. Nearly 300 thousand cards have been automatically reported since the system was online available since November 2022, and the epidemiological characteristics of injury were preliminarily understood, which provide data supports to early earning and interventions of injury. The intelligent injury monitoring system greatly improves the injury monitoring efficiency and card-reporting quality, and saves a large number of manpower and material resources, which provides a powerful technical support to widespread injury monitoring.

Objective To investigate the values of nucleoprotein transformation in sperm for predicting recurrent abortion.Methods A total of 521 infertile couples with complete test indicators on fertility were selected from the reproductive medical clinic of our hospital from 2019 to 2022,among which the ages of the male were from 23 to 56 years old.The following factors causing recurrent abortion were excluded,including the age of woman,body mass index,metabolic disease,antiphospholipid syndrome,uterine and accessory abnormalities,history of caesarean section and intrauterine myoma/cervical conectomy,peripheral blood chromosome abnormalities of both the couple,and adverse life history,such as smoking/alcohol abuse.According to the abortion situation,they were divided into the recurrent abortion group(≥two spontaneous abortions),one spontaneous abortion group and no abortion group.Tukey's multiple comparison was performed to compare the differences of nucleoprotein transformation of sperm in each group by using GraphPad6.0 sta-tistical software.The Pearson method was used to analyze the correlation between nucleoprotein transformation and recurrent abortion.The predictive values of nucleoprotein transformation in recurrent abortion were analyzed by the parameters of sensitivity,specificity,positive predictive value,negative predictive value,Youden index and odd ratio.Results The percentages of abnormal nucleoprotein transformation in recurrent abortion group[(33.31±13.83)％]were significantly higher than those in non-abortion group[(26.85± 15.38)％]and the one abortion group[(28.20±12.50)％,P＜0.05].Pearson correlation analysis showed that there was a significant positive correlation between abnormal nucleoprotein transformation and recurrent abortion.The sensitivity and specificity of nucleoprote-in transformation for predicting recurrent abortion were 45.24％and 73.64％,respectively.All of the data of positive predictive value(15.70％),negative predictive value(92.53％),Youden index(18.88％)and odd ratio(2.31)of nucleoprotein transformation in predicting recurrent abortion were higher than those of high DNA stainability(10.64％,90.31％,1.05％and 1.11).Conclusion In the spouses of patients with recurrent abortion,the immaturity of sperm nuclear protein is significantly increased and significantly posi-tively correlated with recurrent abortion.The abnormal nucleoprotein transformation of sperm may be the important factor of recurrent a-bortion in males,and it has high predictive value for recurrent spontaneous abortion in clinical practice.

Objective:To compare safety and efficacy of one-stage laparoscopic common bile duct exploration plus laparoscopic cholecystectomy (LCBDE+ LC) with endoscopic retrodrade cholangiopancreatography plus laparoscopic cholecystectomy (ERCP+ LC) in elderly patients with concomitant gallbladder and common bile duct (CBD) stones.Methods:This is a two-center retrospective study with clinical data on 492 patients aged over 80 years diagnosed with concomitant gallbladder and CBD stones treated between January, 2014 and December, 2020 at The First Affiliated Hospital of Wenzhou Medical University and Quzhou Hospital Affiliated to Wenzhou Medical University. There were 254 males and 238 females, aged (83.9±3.0) years. These patients were divided into two groups based on their operative methods: the one-stage group (LCBDE+ LC, n=186) and the two-stage group (ERCP+ LC, n=306). Differences in surgery, stones and hospitalization costs were compared between the two groups. Results:When compared with the ERCP+ LC group, the LCBDE+ LC group had significantly higher incidences of previous gastrectomy [21.5%(40/186) vs 4.2%(13/306)], multiple stones [77.4%(144/186) vs 49.3%(151/306)], larger stone diameter [13.7(6.4, 18.6)mm vs 10.9(5.7, 16.1) mm], and increased hospitalization expenditure [(2.37±0.31) Wanyuan vs (3.26±0.44) Wanyuan] (all P<0.05). However, the rates of residual stone [2.7%(5/186) vs 1.3%(4/306)], stone recurrence [2.2%(4/186) vs 5.2%(16/306)], postoperatively overall complications [3.2%(6/186) vs 1.3%(4/306)], and total hospital stay [(10.7±6.2) d vs (11.3±5.4) d] were not significantly different between the two groups (all P>0.05). Conclusions:Allowing for the similar safety and effectiveness, and lower hospitalization expenditure, LCBDE+ LC was a preferred choice for patients aged over 80 year, especially in patients who had previous gastrectomy, multiple large CBD stones, or who could not accept endoscopic procedures for treatment of CBD stones.

Perinatal loss is one of the most serious childbirth trauma,which seriously affects maternal physical and mental health.At present,the management strategy of maternal lactation can be divided into two aspects:milk return and milk donation.Breast milk donation may build new values of perinatal loss,which can promote maternal physical and mental recovery.This article reviewed the conception,status,motivations,facilitators,barriers and interventions of lactation management in women following perinatal loss,so as to provide bases for improving the awareness of obstetric nursing staff,quality of obstetric care and future research on lactation management in women following perinatal loss in China.

Objective:To summarize the clinical characteristics of 4 cases of mixed pituitary adenomas involving growth hormone(GH), prolactin(PRL), and thyroid stimulating hormone(TSH), and explore the standardized management approaches.Methods:The clinical data of four GH/PRL/TSH mixed pituitary adenoma patients diagnosed by Peking Union Medical College Hospital were retrospectively analyzed, including clinical manifestations, biochemical parameters, radiographic characteristics, as well as treatment and prognosis. Then literature review was conducted.Results:Among the 4 patients, 3 were male, with onset ages ranging from 15 to 38 years. All patients presented with coarse facial features as initial symptom. Three patients had visual impairment or visual field defects. All 4 patients had significantly elevated levels of GH and insulin-like growth factor-Ⅰ(IGF-Ⅰ). GH was not inhibited by oral glucose tolerance test. PRL concentration was over 100 ng/mL. Triiodothyronine(T 3)and thyroxine(T 4)were also elevated, while TSH was not inhibited. All pituitary adenomas in four cases were macroadenomas or giant adenomas, all of which were invasive growth, and one case developed pituitary stroke. Except for one patient who did not receive treatment in our hospital due to medical expenses, the remaining three patients underwent a combined treatment of medication and transnasal transsphenoidal pituitary adenoma resection. Among them, one patient had relief of central hyperthyroidism and hyperprolactinemia, but GH/IGF-Ⅰ did not meet the remission criteria. The other two patients had persistent non-resolution of at least 2 hormone axes. Conclusions:Patients with GH/PRL/TSH mixed pituitary adenoma were mainly characterized by coarse facial features, GH/PRL/TSH hyperfunction, large adenoma volume, low biochemical remission after surgery combined with drug treatment, and poor clinical prognosis.

Objective:To explore the clinical application of portable head and neck magnetic resonance imaging (MRI) device in neurosurgery.Methods:A total of 213 patients with brain diseases who were scanned by portable head and neck MRI device in Center of Neurosurgery, Zhujiang Hospital, Southern Medical University from June to September 2022 were selected. The portable head and neck MRI images and 3.0T conventional MRI images of 10 randomly selected patients were compared; the differences in signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) of different sequences were analyzed. Thirty-one patients accepted tracheal intubation/tracheotomy, or ventilator-assisted breathing were selected as special patient group, and another 30 patients were as general patient group; the differences in comprehensive diagnostic scores of portable head and neck MRI images were compared. Noise intensity differences in different sequences between 3.0T conventional MRI and portable head and neck MRI were statistically compared. Twenty hospitalized volunteers with normal hearing in our center from July to August 2022 were selected, conventional 3.0T MRI and portable head and neck MRI were performed successively, and the noise intensity of different sequences in them was evaluated by using a 5-point system.Results:Compared with those in 3.0T conventional MRI images, the SNR and CNR of T1WI, T2WI, and Liquid attenuated reverse recovery sequence (FLAIR) sequences in portable head and neck MRI images were significantly lower ( P<0.05). No significant difference was noted in the comprehensive diagnostic scores of portable head and neck MRI images between special patients and general patients ( P>0.05). Compared with that in the 3.0T conventional MRI, the noise intensity of different sequences in portable head and neck MRI was significantly reduced ( P<0.05). These volunteers had significantly reduced noise intensity scores of different sequences in portable head and neck MRI compared with that in conventional 3.0T MRI ( P<0.05). Conclusion:Portable head and neck MRI device is easy to use, enjoying high safety, imaging quality and suitability, which meets the clinical needs for neurosurgery patients.

In order to investigate the apoptosis triggered by porcine circovirus type 2 (PCV2) in lymphocytes and the underlying mechanism, the levels of apoptosis and the expression levels of miRNA were examined by flow cytometry, Western blotting and real-time PCR (qPCR). The mimics or inhibitors of miR-125a-5p, an apoptosis-related miRNA, were transfected into PK-15 cells, and the apoptosis rate was examined upon overexpression or inhibition of mir-125a-5p. The target gene of mir-125a-5p was predicted by bioinformatics method, and the regulation of mir-125a-5p on the target gene was analyzed by luciferase reporter assay. The expressions of Bcl-2, Bax, cytochrome C and caspase-3 were detected by Western blotting. The results showed that exosomes secreted by PK-15 cells infected with PCV2 significantly increased the lymphocyte apoptosis rate, which was dose-dependent in certain concentration range. The expression of miR-125a-5p was dramatically increased. The apoptosis rate was increased significantly in the cells transfected with miR-125a-5p. It was predicted that there were binding sites of miR-125a-5p at Bcl-2 3'UTR by TargetScan. The luciferase activity of wild-type pmir-Bcl-2 3'UTR was inhibited significantly by miR-125a-5p mimics, but that of mutant pmir-Bcl-2 3'UTR was not changed. By Western blotting, Bcl-2 was reduced significantly, while Bax, cytochrome C and caspase-3 increased significantly, and the ratio of Bcl-2/Bax was significantly decreased. These results showed that PCV2 up-regulated the expression of miR-125a-5p through exosomes, then inhibited the expression of Bcl-2 at both mRNA and protein level, activated mitochondrial apoptosis pathway and induced apoptosis in lymphocytes.

Objective To investigate the expression of autophagy marker in peripheral blood T and B lymphocytes of patients with autoimmune hepatitis (AIH) and its clinical significance. Methods Peripheral blood samples were collected from 62 AIH patients who were treated in Beijing YouAn Hospital affiliated to Capital Medical University from October 2019 to October 2020 who were treated in Beijing YouAn Hospital affiliated to Capital Medical University from October 2019 to October 2020 and 8 healthy controls to detect autophagy of T and B lymphocyte subsets, and then subgroup analyses were performed based on treatment, diagnostic type, and presence or absence of liver cirrhosis and liver failure. The t -test was used for comparison of normally distributed continuous data between two groups; the Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between multiple groups, and the Mann-Whitney U test was used for comparison between two groups; the chi-square test or the Fisher's exact test was used for comparison of categorical data between two groups. Results Compared with the healthy control group, the AIH group had a significantly higher mean fluorescence intensity (MFI) of the autophagy marker LC3B in CD4 + T, CD8 + T, CD19 + B, and CD4 + CD25 + T lymphocytes (all P < 0.05), especially in CD19 + B lymphocytes. The non-treatment group and the partial remission group had a significantly higher MFI of autophagy marker in CD19 + B lymphocytes than the complete remission group ( P =0.037 and 0.040); the idiopathic AIH (I-AIH) group and the drug-induced AIH(DI-AIH) group had a significantly higher MFI than the primary biliary cholangitis (PBC)-AIH overlap syndrome group ( P =0.037 and 0.031); the non-cirrhosis group and the decompensated cirrhosis group had a significantly higher MFI than the compensated cirrhosis group ( P =0.009 and 0.003); the liver failure group had a significantly higher MFI than the non-liver failure group ( P =0.042). The PBC-AIH group had a significantly higher MFI of autophagy marker in CD4 + CD25 + T lymphocytes than the I-AIH group and the DI-AIH group ( P =0.042 and 0.044), the compensated cirrhosis group had a significantly lower MFI than the non-cirrhosis group ( P =0.037), and the non-liver failure group had a significantly higher MFI than the liver failure group ( P =0.043). Conclusion AIH patients have a significant increase in the expression of autophagy marker in peripheral blood T and B lymphocyte subsets compared with healthy individuals, and the level of autophagy is associated with treatment, diagnostic type, and disease severity.
