Objective To investigate the efficacy of laparoscopic cholecystectomy(LC) followed by endoscopic retrograde cholangiopancreaticography(ERCP) for gallbladder and bile duct stones.Methods A total of 58 patients with both gallbladder and bile duct stones received endoscopic sphincterotomy(EST) in our hospital.After the stones were removed,LC was performed on the patients.Results Of the 58 patients,56 were successfully treated with EST and LC.Two cases were unsuccessful owing to difficulty in intubation during ERCP in one and failure to remove all the stones from the bile duct in the other.These two patients were then cured by LC combined with electronic choledochoscopy.Perioperative complications included bleeding during EST in 1,acute edematous pancreatitis in 2,and mild infection of the puncture site in 1.The overall complication rate was 7.1%(4/56).Retained common bile duct stone was observed in 1 patient,and was successfully removed by subsequent ERCP.Conclusions LC combined with ERCP is a safe and effective minimal invasive method for the treatment of concurrent gallstones and bile duct stones.

Objective To investigate the expressions of Ki67,p53,CKL,EMA,S-lOO,NSE,CgA,Syn,CEA and nm23 in adrenal tumors and their clinical significance.Methods Clinical data from 157 cases of adre-nal tumor patients were retrospectively reviewed including the clinical informa-tion and pathology data.Expressions of Ki67,p53,CKL,EMA,S-100,NSE,CgA,Syn,CEA and nm23 proteins were studied by immunohistochemistry(SP method)using monoclonal antibodies,and the relationship of their expressions with histopathologic type and clinical imformation was analyzed with SAS v6.12 software.A P value of＜0.05 was considered statistically significant.Results A increase of the expression rate of CKL,S-100,NSE,CgA,Syn and nm23 in adrenal tumors was obsered(P＜0.05).For univariate analysis,the expression of S-100,CgA,Syn was in connection with histopathologie types(P＜0.05).The expression of S-100,CgA,Syn had positive correlation with each other.The expression of CKL,S-100,NSE,CgA,Syn,nm-23 was no difference between adrnalbenign tumors and malignant tumors(P＞0.05),but it was much higher than in normal adrenal tissues(P＜0.05).The expression of Syn in adrenal cortical adenomaa was higher than in adrenal cortical cancers(P＜0.05),the expression of Ki67 in adrenal cortical adenomas was much lower than in adrenal cortical cancers(P＜0.05).The expression of EMA、CKL in adrenal cortical tumors were higher than in adrenal medullary tumors(P＜0.05),the expression of S-100,Syn,NSE,CgA in adrenal cortical tumors were lower than in adrenal medullary tumors(P＜0.05).Conclusions CKL,S-100,NSE,CgA,Syn and nm23 were good markers for adrenal tumors,they could be use for the adrenal tumors diagnosis.Detect Syn and Ki67 simutaneously was helpful to the diagnosis of adrenal cortical tumors.Detect EMA,CKL,S-100,Syn,NSE and CgA simultaneously and combine with clinical data was helpful to diagnosis between adrenal cortical tumors and adrenal medullay tumors.In malignant tumors,blood pressure had positive correlation with the expression of CgA,the size of tumor had neg-ative correlation of blood pressure,no prognostic factor was found.

Objective To provide the dose information from the epidemiological cohort established in 1980 in Jiangsu province using normalized workload method,and to estimate cumulative skin dose to medical diagnostic X-ray workers based on personal dosimeter were worn as members of the epidemiologicat cohort.Methods Data for fixed cohort members of X-ray exposure history from 1950 to June 2011 were collected.According to correction factors such as examination types and protection conditions,exposure doses from 1950s to June of 2011 were estimated through a Visual Basic language program.Results Average annual doses vary significantly between during different time periods:10.1 (6.1-12.3) mGy/year during 1950-1965,3.5 (2.1-5.4) mGy/year for 1966-1984 and 1.3 (0.9-1.9) mGy/year during 1985-2011,respectively.Conclusions Average annual doses received by 3 961 medical diagnostic X-ray workers during different time periods in this investigation are nearly consistent with the results reported previously and show a roughly similar trend.

Total 786 cases of acute uncomplicated appendicitis(UCAA) were included for analysis.All the cases were given antibiotics as a main treatment.Clinical cure rate and the number of cases requiring surgery were observed.Patients with conservative treatment were followed up and the recurrence was observed.Logistic regression was applied to analyze the risk factors of recurrence.Among 786 cases,774 (98.5％) were treated conservatively and achieved clinical cure;68 cases (9.0％) had recurrence during follow-up,the median time to recurrence was 11 months (1-33 months).Logistic regression analysis showed that age(OR =1.124,95％ CI:1.067-3.790,x2 =2.767,P =0.041) and appendix bezoar (OR =1.649,95％ CI:1.281-4.055,x2 =3.935,P =0.027) were independent risk factors for recurrence.Non-operative treatment for acute uncomplicated appendicitis shows a good short and long term effects.Surgical excision may be a better choice for the patients with high risks of recurrence.

Objective Wnt signaling plays an important role in the development and progression of renal cell carcinoma (RCC).This study aimed to evaluate the effects of the Wnt signaling inhibitor 15-oxospiramilactone on the proliferation , migration, cell apoptosis, and cycles of the human RCC cell line 786-0, and to investigate the possible mechanisms of this small molecule acting on RCC in ivtro. Methods We treated 786-0 cells with DMSO ( blank control group ) and 15-oxospiramilactone at the concentrations of1.25μmol/L (low 15 -OSL), 2.5μmol/L (medium 15-OSL), and 5μmol/L (high 15-OSL), respectively, for 72 hours.Then we observed the changes in the proliferation and migration of the 786-0 cells by MTT and scratch-wound assay and determined their apopto-sis and cycles by Annexin V-FITC/PI assay and flow cytometry . Results 15-oxospiramilactone significantly inhibited the growth of the 7860-cells, with the IC 50of 1.088 μmol/L at 72 hours, and decreased their migration distance (P<0.05).After 36 hours of treatment, the apoptosis rates of the 786-0 cells in the low, medium, and high 15-OSL groups were (12.17 ±0.56), (18.54 ± 1.07), and (50.74 ±1.28) %, respectively, significantly increased as compared with (7.85 ±0.42) %in the blank control group (P<0.05), and in an obviously concentration-dependent manner.15-oxospiramilactone remarkably reduced the number of cells in the G0/G1 phase and increased that in the G 2/M phase (P<0.05). Conclusion 15-oxospiramilactone can significantly inhibit the pro -liferation and migration and induce the apoptosis of 786-0cells in vitro.It may be a potential anti-RCC agent.

Cognitive dysfunction,predominantly a consequence of neurodegenerative disorders,is a burgeoning health issue.Odor molecules have the unique ability to circumvent the blood-brain barrier through the olfactory pathway,exerting a direct influence on cognitive-related brain regions including the entorhinal cortex,hippocampus,and amygdala,without transiting through the thalamus.These olfactory molecules,mostly sourced from natural plant essential oils,are character-ized by significant volatility,minimal adverse reactions,and abundant availability.Hence,research into and applications of olfactory stimulation in improving cognitive dysfunction have raised widespread concerns.This article reviews the rela-tionship between the olfactory pathway and cognitive brain regions,and explores the mechanism by which natural plant es-sential oils alleviate cognitive dysfunction through olfactory stimulation in order to provide a reference for improving cogni-tive function via olfactory stimulation.

Breast cancer is the most diagnosed cancer in women worldwide and the leading cause of most cancer-related deaths,posing a serious threat to women′s health worldwide.At present,although the prognosis of some patients with breast cancer has improved,the emergence of drug resistance and the metastasis and recurrence of breast cancer are still the main reasons for poor prognosis.CD36 is a multiligand transmembrane glycoprotein expressed on various cell types.In recent years,studies have confirmed that CD36 can reshape the lipid metabolism of cancer cells;promote the differentiation of tumor-related macrophages into M2 type and recruitment into tumor tissues;regulate the function of Treg cells,CD8+T cells,DCs,and other immune cells,and thus promote tumor development.In addition,CD36 is also associated with breast cancer stem cells,metastasis-initiating cells,and breast drug resistant cells.Therefore,CD36 could be an important potential therapeutic target for breast cancer.

Objective To study the influence of rosemary essential oil inhalation on the memory of mice experiencing sleep deprivation and to delineate the possible mechanisms involved.Methods C57BL/6J mice were randomly divided into four experimental groups in this study:a control group(Con),a control group with rosemary essential oil inhalation(Con+REO),a sleep deprivation group(SD)and a sleep deprivation group with rosemary essential oil inhalation(SD+REO).A 72-hour sleep deprivation model was induced using the multiple platform water environment method,with the Con+REO and SD+REO groups exposed to rosemary essential oil inhalation.Cognitive function was evaluated through Y-maze and novel object recognition tests.The hippocampal tissue was analyzed for superoxide dismutase(SOD)activity and the concentrations of malondialdehyde(MDA)and glutathione(GSH).ELISA was used to determine the levels of norepinephrine(NE),dopamine(DA),and serotonin 5-hydroxytryptamine(5-HT)in the hippocampus.The expression levels of postsynaptic density 95(PSD95)and brain-derived neurotrophic factor(BDNF)in the hippocampus were determined using immunoblotting techniques.Results Compared with the Con and Con+REO groups,the SD group demonstrated a significant reduction in the spontaneous alternation percentage in the Y-maze as well as the novel object recognition index.Additionally,there was a pronounced decrease in hippocampal SOD activity and GSH content,a substantial elevation in MDA levels,and a decrease in the levels of DA,NE,and 5-HT.The expressions of PSD95 and BDNF proteins also decreased.In comparison with the SD group,the SD+REO group exhibited a significant increase in the spontaneous alternation percentage in the Y-maze and the novel object recognition index.There was also a marked increase in hippocampal SOD activity and GSH content,a reduction in MDA levels and elevated levels of NE and DA.Moreover,the expressions of PSD95 and BDNF proteins were upregulated.Conclusion The inhalation of rosemary essential oil enhances the memory of sleep-deprived mice,and the underlying mechanism may involve the mitigation of oxidative stress within the hippocampal tissue,the modulation of neurotransmitter levels,and the facilitation of synaptic plasticity.

Objective:To investigate the effectiveness and prognosis of using improved domestic neonatal ureteral stents (referred to as improved double-J stents) for thoraco-amniotic shunting (TAS) in treating fetal chylothorax.Methods:A retrospective analysis was conducted on the clinical data of 21 cases of fetal chylothorax treated with TAS using improved double-J stents at Nanjing Drum Tower Hospital, Nanjing University Medical School from April 1, 2018, to September 30, 2023. Surgical complications and perinatal outcomes were summarized, and the development of surviving infants in five domains (communication, gross motor, fine motor, problem-solving, and personal-social) was assessed using the Ages and Stages Questionnaires-Third Edition (ASQ-3). Descriptive statistical analysis was used. Results:(1) The median gestational age at prenatal diagnosis was 28.7 weeks (27.3-30.4 weeks), with 85.7% (18/21) of cases complicated by fetal hydrops, 90.5% (19/21) by polyhydramnios, and 85.7% (18/21) by bilateral pleural effusion. (2) The median gestational age at the first TAS was 30.9 weeks (29.7-32.7 weeks). Of the 21 cases, 10 required repeat stent placement due to dislodgement or blockage, with a total of 49 stent placements. The dislodgement rate within 7 days was 24.5% (12/49), and the blockage rate was 16.3% (8/49). The rate of premature rupture of membranes within one week post-stent placement was 9.5% (2/21), with an overall preterm premature rupture of membranes rate of 28.6% (6/21). The median interval from the first TAS to delivery was 30.0 d (19.8-40.0 d). Of the 21 cases, three opted for selective termination of pregnancy; the remaining 18 cases resulted in live births, with a median gestational age at delivery of 35.6 weeks (34.1-37.1 weeks), and three neonatal deaths. The overall neonatal survival rate was 15/18. Surviving infants were followed up to a median age of 30 months (7-48 months), with 13 showing normal development and two scoring below the ASQ-3 threshold.Conclusion:The improved double-J stent can be used for TAS in the treatment of fetal chylothorax, with generally favorable outcomes.

Objective:To establish a common method for detecting serotypes of respiratory adenovirus, and to detect the main serotypes of respiratory human adenovirus (HAdV) infection in children in Wenzhou area.Methods:A multiplex PCR method based on capillary electrophoresis was developed to detect 12 common serotypes of respiratory adenovirus.A total of 1 059 children with acute respiratory infection who were admitted to Yuying Children′s Hospital Affiliated to Wenzhou Medical University from January 2018 to December 2019 with positive infection of HAdV detected by the direct immunofluorescence method were recruited and retrospectively analyzed.Multiplex PCR was performed to determine 12 serotypes of respiratory adenovirus, including HAdV-1, 2, 3, 4, 5, 7, 14, 21, 37, 40, 41 and 55.Meanwhile, some samples were randomly selected to examine the consistency in the detection result by the first-generation sequencing method.Results:A total of 1 059 specimens of respiratory secretions with positive HAdV antigen were collected.Detected by multiplex PCR method, 947 cases (89.4%) were positive for 1 serotype, 13 cases (1.2%) were mixed infection with 2 serotypes, and 24 cases (2.3%) were negative.In addition, 75 cases(7.1%) were positive but could not be serotyped.Among the 947 children with the positive infection of a single serotype, 415 cases (43.8%) were HAdV-3 in subgroup B, 318 cases(33.6%) were HAdV-7, 12 cases (1.2%) were HAdV-55, 2 cases (0.2%) were HAdV-21, 108 cases (11.4%) were HAdV-2 in subgroup C, 70 cases (7.4%) were HAdV-1, 16 cases(1.7%) were HAdV-5, and 6 cases(0.6%) were HAdV-4 in subgroup E. HAdV-14, HAdV-37, HAdV-40 and HAdV-41 were not detected.A total of 51 positive samples of HAdV infection detected by multiplex PCR were randomly selected to compare with the detection result by the first-generation sequencing, which were all consistent.Conclusions:This study successfully established a multiplex PCR based on capillary electrophoresis in diagnosing common serotypes of respiratory adenovirus infection in children.HAdV-3, HAdV-7 of subgroup B and HAdV-2 and HAdV-1 of subgroup C were the main serotypes of respiratory adenovirus infection in children of Wenzhou area.HAdV-14, HAdV-37, HAdV-40 and HAdV- 41 were not detected.
