Objective : To investigate the antidepressant effects and the underlying mechanisms of tetrahydrocurcumin(THC) and its nanoparticle formulation(THCN). Methods : Forty-six male ICR mice were randomly divided into Con group, LPS group, THC group, THCN group and SER group. A mouse depression model was established by intraperitoneal administration of LPS. The anxiety and depression-like behaviors of mice were evaluated by open field test(OFT) and forced swimming test(FST). Myelin staining was applied to assess the extent of demyelination in the prefrontal cortex of the mice. The prefrontal cortex and hippocampus were further examined for the expression levels of glial fibrillary acidic protein(GFAP) and Toll-like receptor 4(TLR4) through quantitative immunofluorescence assays. Results : Compared with the Con group, the LPS group showed increased anxiety-like and depressive-like behaviors in both the long-term and short-term experiments(P<0.05); the degree of demyelination increased in the LPS group of the long-term experiment(P<0.01); the expression of GFAP was reduced in the LPS group of the short-term experiment(P<0.01), while the expression of TLR4 increased(P<0.05); the expression of TLR4 decreased in the THC group(P<0.01); the expression of GFAP in the prefrontal cortex of the THCN group was reduced(P<0.01), while the expression of TLR4 increased(P<0.05). Compared with the LPS group, the THC group showed reduced depressive-like behaviors in the long-term experiment(P<0.05), while the anxiety-like and depressive-like behaviors of the THCN group and the SER group were reduced(P<0.05), and the anxiety-like and depressive-like behaviors of the THC group and the THCN group were reduced in the short-term experiment(P<0.05); the degree of demyelination was reduced in the THC group, THCN group and SER group in the long-term experiment(P<0.05); the expression of GFAP increased in the THC group of the short-term experiment(P<0.05), while the expression of TLR4 was reduced(P<0.05), and the expression of GFAP increased in the THCN group(P<0.05). Compared with the THC group, the THCN group and the SER group showed reduced anxiety-like behaviors in the long-term experiment(P<0.05); the expression of GFAP in the prefrontal cortex of the THCN group was reduced in the short-term experiment(P<0.05), while the expression of TLR4 in the hippocampal DG area increased in the short-term experiment(P<0.01). Conclusion Tetrahydrocurcumin and its nanoparticle formulation both exert significant ameliorative effects on depression-like behaviors and demyelination in mice induced by lipopolysaccharide. The antidepressant mechanism of THC appears to be mediated through the down-regulation of TLR4 and the up-regulation of GFAP. The mechanism underlying the antidepressant action of THCN seems predominantly focused on the enhancement of GFAP expression.

Primary hepatic cancer is one of the major problems that need to be solved urgently in the field of public health, seriously endangering the life and health of Chinese people. Its treatment mode is multidisciplinary participation and synergy of multiple therapeutic methods. Even though there are many common clinical treatments for liver cancer in China, its therapeutic outcome is still unsatisfactory. yttrium-90 has been applied for more than 20 years, and a large amount of foreign clinical data have been accumulated. Combining the latest literature and clinical practice, the authors describe the clinical application and research progress of yttrium-90 micro-sphere selective internal radiation therapy in primary liver cancer.

Objective To compare the clinical efficacy and safety of cyclopofol injection and propofol injection combined with afentanil injection in patients undergoing tracheoscopy under laryngeal mask ventilation under general anesthesia.Methods The patients to undergo tracheoscopy were randomly divided into treatment group and control group.Induction of anesthesia:treatment group received 20 μg·kg-1 afentanil,0.4 mg·kg-1 ciprofol and 0.2 mg·kg-1 cisatracurium;control group received 20 μg·kg-1afentanil,2 mg·kg-1 propofol and 0.2 mg·kg-1 cisatracurium.Two groups were given laryngeal mask ventilation for general anesthesia.The treatment group received 0.8 mg·kg-1·h-1 cypofol and 0.5-1.0 μg·kg-1·min-1 afentanil to perform the anesthesia maintenance;the control group was received 8 mg·kg-1·h-1propofol and 0.5-1.0 μg·kg-1·min-1 afentanil to perform the anesthesia maintenance.The vital signs,induction and recovery time,dosage of afentanil during anesthesia and safety were compared between the two groups.Results Treatment group were enrolled 70 cases,10 cases dropped out,and 60 cases were finally included in the statistical analysis.Control group were enrolled 70 cases,10 cases dropped out,and ultimately 60 cases were finally included in the statistical analysis.Three minutes after induction of anesthesia(T1),the mean arterial pressure(MAP)of treatment group and control group were(79.32±5.73)and(73.15±6.20)mmHg,the heart rate(HR)were(70.53±8.20)and(65.77±7.75)beat·min-1,respectively.At insert the bronchoscope(T2),MAP of treatment group and control group were(82.52±5.81)and(75.99±6.09)mmHg,HR were(70.27±7.94)and(65.42±7.73)beat·min-1,respectively.The MAP and HR of treatment group at T1 and T2 were significantly higher than those of control group at the same time,the differences were statistically significant(all P＜0.05).The induction time of treatment group and control group was(76.23±6.51)and(66.93±6.26)s,and the difference was statistically significant(P＜0.05).The eye opening time during anesthesia recovery of treatment group and control group was(8.42±1.94)and(8.48±2.13)min,the intraoperative dosage of fentanyl was(3 456.67±608.51)and(3 515.00±619.41)μg,respectively,the differences of above indexes in two groups were not statistical significance(all P＞0.05).The incidences of injection pain during induction period in treatment group and control group were 3.33％and 30.00％,the incidences of hypotension in treatment group and control group were 18.33％and 40.00％,the incidences of intraoperative bradycardia in treatment group and control group were 3.33％and 13.33％,respectively,the differences were statistically significant(all P＜0.05).Conclusion Compared with propofol injection combined with afentanil injection,cipofol injection combined with afentanil injection can better maintain hemodynamic stability during anesthesia induction and maintenance in patients undergoing tracheoscopy under general anesthesia with laryngeal mask ventilation,and has better safety.

Objective:To explore the characteristics of SLCO1B1/ SLCO1B3 gene variants among children with Rotor syndrome (RS). Methods:Four children who were admitted to the Department of Hepatology of Hunan Children′s Hospital between January 2019 and January 2022 were selected as the study subjects. Trio-whole exome sequencing was carried out for the four families, and gel electrophoresis was used to verify an insertional variant of long-interspersed element-1 (LINE-1).Results:Genetic testing has identified three variants of the SLCO1B1 gene, including c. 1738C>T (p.R580*), c. 757C>T (p.R253*) and c. 1622A>C (p.Q541P), and two variants of the SLCO1B3 gene, including c. 481+ 22insLINE-1 and c. 1747+ 1G>A among the children. Three of them were found to harbor homozygous variants of the SLCO1B1/ SLCO1B3 genes, and one has harbored compound heterozygous variants. Sanger sequencing confirmed the existence of all variants, and gel electrophoresis has confirmed the existence of the LINE-1 insertional variant of about 6 kb within intron 6 of the SLCO1B3 gene in all children. Conclusion:The pathogenesis of the RS among the four children may be attributed to the variants of the SLCO1B1/ SLCO1B3 genes. The LINE-1 insertion variant of the SLCO1B3 gene may be common among Chinese RS patients.

Objective:To evaluate the surgery combined chemotherapy and radiation in locally advanced neuroendocrine carcinoma of the cervix (NECC) .Methods:This is a single-center retrospective cohort study. Locally advanced NECC patients admitted to Peking Union Medical College Hospital, Chinese Acadmy of Medical Sciences from January 2011 to April 2022 were enrolled. They were divided into concurrent chemoradiotherapy group, and surgery combined with chemotherapy and radiation group. The Kaplan-Meier method was used to analyze the progression free survival (PFS), overall survival (OS), recurrence rate, and mortality rate.Results:(1) Forty-six cases were included, 22 in concurrent chemoradiotherapy group, 24 in surgery combined chemotherapy and radiation group. With 16 patients (35%, 16/46) received neoadjuvant chemotherapy (NACT), the NACT effective rate was 15/16. (2) The median follow-up time was 27.5 months (range: 10-106 months), with 26 (57%, 26/46) experienced recurrences. There were 4 (9%, 4/46) pelvic recurrences and 25 (54%, 25/46) distant recurrences, and 3 (7%, 3/46) both pelvic and distant recurrences. Compared with concurrent chemoradiotherapy group, surgery combined chemotherapy and radiation group had lower pelvic recurrence rate [14% (3/22) vs 4% (1/24); χ2=1.296, P=0.255] but without statistic difference. Both groups had similar distant recurrence rate [55% (12/22) vs 54% (13/24); χ2=0.001, P=0.979] and overall recurrence rate [59% (13/22) vs 54% (13/24); χ2=0.113, P=0.736]. (3) During the follow-up period, 22 cases (48%, 22/46) died, with 11 cases (50%, 11/22) in concurrent chemoradiotherapy group and 11 cases (46%, 11/24) in surgery combined chemotherapy and radiation group, without significant difference ( χ2=0.080, P=0.777). The postoperative 3-year and 5-year OS rates were 62.3% and 36.9%. Compared with concurrent chemoradiotherapy group, the patients in surgery combined chemotherapy and radiation group showed an extended trend in PFS (17.0 vs 32.0 months) and OS (37.0 vs 50.0 months) but without statistic differences ( P=0.287, P=0.125). Both groups had similar 3-year OS rate (54.2% vs 69.9%; P=0.138) and 5-year OS rate (36.1% vs 38.8%; P=0.217). Conclusions:Our study supports the multi-modality treatment strategy (including surgery, chemotherapy and radiation) as an important component in the treatment of locally advanced NECC. The combination of surgery, chemotherapy and radiation seems to have advantages in the treatment of locally advanced NECC, but needs to be confirmed by further multicenter studies.

Objective:To investigate the safety and short-term efficacy of yttrium-90 [ 90Y] resin microspheres transarterial radioembolization (TARE) for the treatment of initial unresectable malignant hepatic tumor. Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 10 patients with initial unresectable malignant hepatic tumor who were admitted to The First Affiliated Hospital of Army Medical University from June 2022 to June 2023 were collected. All patients were males, aged (57±4)years. Measurement data with normal distribution were represented as Mean± SD, and comparison before and after treatment within the group was conducted using the paired t test. Measurement data with skewed distribution were represented as M( Q1, Q3) or M(range), and comparison before and after treatment within the group was conducted using the paired rank sum test. Count data were described as absolute numbers or proportions. Results:(1) Pre-treatment assessment. All 10 patients completed pre-treatment assessment, with 8 cases undergoing once of technetium 99-polymerised protein perfusion test and 2 cases under-going ≥ twice of technetium 99-polymerised protein perfusion test. The ratio of uptake of techne-tium 99-polymerised protein in tumor tissue to normal tissue, the hepatopulmonary shunting ratio and the therapeutic requirement of 90Y resin microspheres in 10 patients were 5.8±1.2, 4.8%±0.8% and (1.10±0.20)GBq, respectively. (2) Treatment strategy of 90Y resin microspheres TARE. Of the 10 patients, cases treated with whole tumor radioembolisation, radioembolisation of the main target lesion+non-target lesion radiofrequency ablation, radioembolisation of the main target lesion+non-target lesion iodine-125 particles implantation, radioembolisation of the liver lobe or liver segment were 6, 2, 1, 1, respectively. During the treatment period, one elderly case did not receive target therapy combined with immunotherapy due to intolerance, and the remaining 9 cases received target therapy combined with immunotherapy. Of the 10 patients, there were 7 cases receiving once of 90Y resin microspheres TARE, and 3 cases receiving twice of 90Y resin microspheres TARE. (3) Follow-up. All 10 patients were followed up for 4.5(range, 3.0-12.0)months. During the follow-up, none of patient had adverse event associated with 90Y resin microspheres TARE. The tumor diameter, alpha-fetoprotein (AFP), abnormal prothrombin, alanine aminotransferase (ALT), aspartate amino-transferase (AST), albumin (Alb), total bilirubin (TBiL), glutamyltransferase (GGT) of the 10 patients were 96(72,135)mm, 26(6,833)μg/L, 290(56,2 997)Au/L, (36±13)IU/L, (41+16)IU/L, (40±4)g/L, (15.3±4.1)μmol/L, (99±68)IU/L before receiving 90Y microspheres TARE. The above indicators of the 10 patients were 63(43,97)mm, 4(3,357)μg/L, 38(25, 142) Au/L, (40±16)IU/L, (51±28)IU/L, (39±4)g/L, (14.4±1.2) μmol/L, (134±93)IU/L after 90 days of receiving 90Y microspheres TARE. There were significant differences in tumor diameter and abnormal prothrombin ( Z=-2.08, -2.24, P<0.05) and there was no significant difference in AFP, ALT, AST, Alb, TBil, GGT ( Z=-1.27, t=0.63, 1.69, 1.73, 0.67, 1.30, P>0.05). During the follow-up period, 5 cases achieved clinical complete response, 4 cases achieved clinical partial remission, and 1 case experienced non-target lesion progression within 30 days after receiving 90Y resin microspheres TARE. The disease remission rate and disease control rate of the 10 patients were 9/10 and 9/10, respectively. None of patient died during follow-up period. Conclusion:90Y resin microspheres TARE for the treatment of initial unresectable malignant hepatic tumor is safe and feasible, and can achieve satisfactory short-term efficacy when combined with other treatment methods.

AIM:To investigate the effects of Panax notoginseng compound formula(PN)on endometrial fibro-sis by regulating inflammatory reaction and intestinal flora(IF)in a rat model of intrauterine adhesion(IUA).METHODS:The rat IUA model was established by following the mechanical injury method.A total of 50 rats were randomly divided in-to sham group,model group,low-dose(210 mg/kg)PN group,medium-dose(420 mg/kg)PN group and high-dose(840 mg/kg)PN group.After 8 weeks of intragastric administration,the uterus was collected to observe morphological changes with naked eye.The degree of uterine tissue damage and fibrosis was evaluated through hematoxylin-eosin(HE)and Mas-son staining.The collagen type Ⅰ(Col Ⅰ)was detected by immunohistochemistry.The interleukin-6(IL-6)and IL-10 pro-tein expression was detected by Western blot.The levels of IL-6,IL-1β,tumor necrosis factor-α(TNF-α)and vascular endothelial growth factor B(VEGFB)were detected by enzyme-linked immunosorbent assay(ELISA).The IF diversity and population structure were observed by 16S amplicon.RESULTS:Compared with the sham group,the uteruses of rats in the model group showed:reduced elasticity,accompanied by congestion and edema;decreased number of glands and blood vessels,and thinned endometrium(P<0.01);increased collagen fibers and Col Ⅰ protein expression(P<0.01);sig-nificantly increased IL-1β,IL-6,TNF-α and VEGFB levels in the uterine tissue(P<0.01);decreased IL-10 level(P<0.01);and reduced IF diversity(P<0.05).Compared with the model group,the drug intervention groups exhibited:re-covered elasticity of the uterus and relieved congestion and edema;increased number of endometrial glands and blood ves-sels(P<0.05);decreased collagen fibers and Col Ⅰ protein expression(P<0.01);reduced IL-1β,IL-6,and TNF-α lev-els to varying degrees in the uterine tissue(P<0.05);elevated IL-10 level(P<0.01);and improved IF diversity(P<0.05).CONCLUSION:The PN is able to significantly improve the endometrial tissue fibrosis in IUA rats.The under-lying mechanisms may be related to the inhibition of IL-6,IL-1β and TNF-α expression,up-regulation of IL-10,and im-provement of IF diversity.

Objective To construct and apply a management plan for microaspiration of oropharyngeal secretions in ICU intubated patients.Methods Based on evidence summaries and expert consultation,a management plan for microaspiration of oropharyngeal secretions in ICU intubated patients was constructed,consisting of 19 items covering 7 aspects including identification of risk factors,position management,tube and cuff selection,cuff management,mechanical ventilation management,pain and sedation management,removal of oropharyngeal and subglottic secretions,and oral care.Convenience sampling was used to select 141 ICU intubated patients from a tertiary A comprehensive hospital in Suzhou from June,2022 to September,2023.Patients were divided into an experimental group(n=72)and a control group(n=69)according to the wards.The experimental group received the management plan for microaspiration of oropharyngeal secretions in ICU intubated patients.The control group received the nursing bundle for ventilator associated pneumonia(VAP).The incidence and time from intubation to microaspiration and VAP,duration of mechanical ventilation,ICU length of stay,and disease outcome were compared between the 2 groups.Results The incidence of microaspiration of oropharyngeal secretions,the duration of mechanical ventilation,time from intubation to microaspiration showed significant differences between the 2 groups(P<0.05).There were no significant differences in the incidence of ventilator associated pneumonia,ICU length of stay,and disease outcome between the 2 groups(P>0.05).The time from intubation to VAP in the experimental group was 7.5 days,and that in the control group was 3.8 days.Conclusion The application of the management plan for microaspiration of orophaiyngeal secretions in ICU intubated patients is beneficial for reducing the incidence of microaspiration,delaying the time from intubation to microaspiration and VAP,and shortening the duration of mechanical ventilation.
