Previous studies have found that As2 O3 can interfere with serum thyroid hormone TH levels in rats and cause chronic liver damage,but the mechanism remains unclear.In order to ex-plore the role of TH signaling pathway in As2 O3-induced chronic liver injury,qRT-PCR and West-ern blot techniques were used to detect the expression changes of genes and protein of TRβ1(a key regulator of TH signaling pathway in rat liver)and cyclin D1(the downstream factor of TRβ1 in nuclear pathway).Meanwhile,the changes in the protein of key factors(Bax,Bcl-2)of the TH sig-nal nuclear outside pathway were detected.The results indicated that:after As2 O3 treatment for 110 days,compared with the control group,the expression of TRβ1 protein in the liver of female mice significantly decreased(P＜0.01),the expression of cyclin D1 significantly increased in the 0.1 and 0.2 mg/L groups(P＜0.01).Meanwhile,the expression of TRβ1 protein in male mice sig-nificantly decreased in 0.4 mg/L group(P＜0.01),and the expression of cyclin D1 in each group significantly increased(P＜0.01).The mRNA expression results were basically the same as those of protein expression.After As2 O3 treatment for 194 days,compared with the control group,the expression of TRβ1 protein in each group significantly decreased(P＜0.01),and the expression of cyclin D1 significantly increased(P＜0.01).The mRNA expression results were basically consist-ent with the protein.As2 O3 interfered with the expression of Bcl-2 and Bax proteins in rats and in-duced the increase in the ratio of Bcl-2/Bax protein as the action time increased.Among them,the Bcl-2/Bax ratio of female rats in each group and male rats in the 0.4 mg/L group significantly in-creased(P＜0.01),and male rats in the 0.1 mg/L group significantly increased(P＜0.05).It shows that As2O3 can cause abnormal levels of TRβ1,cyclin D1 and the Bcl-2/Bax ratio in rat liv-er.

Objective:To compare the diagnostic efficacy of 22 G fine needle aspiration (FNA) needles and 22 G end-cutting fine needle biopsy (FNB) needles for solid pancreatic lesion using both cytological and histological examination.Methods:Clinical data of 116 patients who underwent endoscopic ultrasound-guided fine needle aspiration/biopsy (EUS-FNA/FNB) at the Digestive Endoscopy Center of Ruijin Hospital, Shanghai Jiao Tong University School of Medicine from June 2022 to March 2023 were retrospectively analyzed. Sixty-three patients sampled with 22 G FNA needles were the FNA group, and 53 sampled with 22 G FNB needles were the FNB group. The diagnostic accuracy, sensitivity, specificity, positive predictive value, negative predictive value, and cytological and histological diagnostic yield of FNA needles and FNB needles for solid pancreatic lesions were compared.Results:There were no significant differences in age, gender, lesion location, lesion size, or the number of passes between the FNA group and the FNB group ( P>0.05). There were no significant differences in the diagnostic accuracy [93.7% (59/63) VS 90.6% (48/53), P=0.730], sensitivity [93.0% (53/57) VS 90.2% (46/51), P=0.732], specificity [100.0% (6/6) VS 100.0% (2/2), P=1.000], positive predictive value [100.0% (53/53) VS 100.0% (46/46), P=1.000] and negative predictive value [60.0% (6/10) VS 28.6% (2/7), P=0.335] of combined cytology and histology in distinguishing benign and malignant lesions between the two groups. In the FNA group, the diagnostic accuracy of combined cytology and histology was higher than cytology alone [93.7% (59/63) VS 81.0% (51/63), P=0.008], and was higher than histology alone without statistical significance [93.7% (59/63) VS 87.3% (55/63), P=0.125]. In the FNB group, the diagnostic accuracy of combined cytology and histology was higher than cytology alone [90.6% (48/53) VS 69.8% (37/53), P=0.001], but not than histology alone [90.6% (48/53) VS 90.6% (48/53)， P=1.000]. For solid masses located in pancreatic body/tail, the diagnostic accuracy for malignancy by histology using FNB needles tended to be higher than that of FNA needles [100.0% (17/17) VS 81.3% (26/32), P=0.080]. Conclusion:Both FNA needles and FNB needles exhibit adequate diagnostic yield for solid pancreatic masses when combining cytology and histology. FNB needles may offer a higher histological diagnostic yield.

Glioblastoma(GBM)is a lethal cancer with limited therapeutic options.Dendritic cell(DC)-based cancer vaccines provide a promising approach for GBM treatment.Clinical studies suggest that other immu-notherapeutic agents may be combined with DC vaccines to further enhance antitumor activity.Here,we report a GBM case with combination immunotherapy consisting of DC vaccines,anti-programmed death-1(anti-PD-1)and poly I:C as well as the chemotherapeutic agent cyclophosphamide that was integrated with standard chemoradiation therapy,and the patient remained disease-free for 69 months.The patient received DC vaccines loaded with multiple forms of tumor antigens,including mRNA-tumor associated antigens(TAA),mRNA-neoantigens,and hypochlorous acid(HOCl)-oxidized tumor lysates.Furthermore,mRNA-TAAAs were modified with a novel TriVac technology that fuses TAAs with a destabilization domain and inserts TAAs into full-length lysosomal associated membrane protein-1 to enhance major histo-compatibility complex(MHC)class Ⅰ and Ⅱ antigen presentation.The treatment consisted of 42 DC cancer vaccine infusions,26 anti-PD-1 antibody nivolumab administrations and 126 poly I:C injections for DC infusions.The patient also received 28 doses of cyclophosphamide for depletion of regulatory T cells.No immunotherapy-related adverse events were observed during the treatment.Robust antitumor CD4+and CD8+T-cell responses were detected.The patient remains free of disease progression.This is the first case report on the combination of the above three agents to treat glioblastoma patients.Our results suggest that integrated combination immunotherapy is safe and feasible for long-term treatment in this patient.A large-scale trial to validate these findings is warranted.

Objective To provide evidence for the presence of the lower body fascia chain. Methods Totally 20 cases of Chinese adult femur were selected, and the anatomy was performed to observe the continuity on fascia between periosteal fascia and iliotibial tract (ITT). Judging the generic character and the degree of continuity of them. If there was a significant anatomical continuity between them, the tensile strength of the structure is tested by applying a certain tension to both. Results First, an indirect link between the iliotibial tract and the fibular myofascial fascia was found: in all anatomical lower extremity specimens, the iliotibial bundle (ITT) was structurally connected to the fascial fascia, which was almost inseparable from the fibular fascia. Second, the application of tension to the iliotibial tract (ITT) could cause local movement between the fascia of the calf and the periosteal fascia. Conclusion Iliotibial tract and fibular long muscle fascia are connected firmly. The stability of the connection suggests that it may play a role in the conduction of a certain tension.

Organic carbonates (OCs) are a class of compounds featured by a carbonyl flanked by two alkoxy/aryloxy groups. They exist in either linear or cyclic forms, of which the majority encountered in nature adopt a pentacyclic structure. However, the enzymatic basis for pentacyclic carbonate ring formation remains elusive. Here, we reported that a four-protein metabolon (AlmUII-UV) assembled by a small peptide protein (AlmUV) appends a reactive

Ultrasound-guided fascial space block, such as transversus abdominis plane block and quadratus psoas block, has been widely used in postoperative analgesia in delivery woman. This paper reviews the application of ultrasound-guided fascial space block in postoperative analgesia of cesarean section in recent years, in order to provide reference for further clinical application.

Objective: To compare the difference of the clinical and laboratory characteristics between γδ T-cell large granular lymphocyte leukemia (γδT-LGLL) and αβ T-cell large granular lymphocyte leukemia (αβT-LGLL) . Methods: The clinical and laboratory characteristics of 17 patients with γδT-LGLL and 91 patients with αβT-LGLL in the department of therapeutic center of anemia of enrolled in our hospital from January 2009 to January 2019 were retrospectively analyzed. Results: The median age of the 17 patients with γδT-LGLL was 54 years (range, 25-73 years) , the most common presenting symptom was anemia. In comparison with αβT-LGLL patients, splenomegaly was common (41% and 44%, respectively) , whereas hepatomegaly (12% and 5%, respectively) and lymphadenopathy (6% and 8%, respectively) were rare. The positive rates of antinuclear antibody (59% and 45%, respectively) were high, whereas the positive rates of rheumatoid factor (6% and 10%, respectively) were rare for both groups. There were no differences on peripheral blood counts between the two groups. However, γδT-LGLL patients were found to be predominantly expressed a CD4(-)/CD8(-) phenotype. Steroid therapy with prednisone was used alone as first-line therapy for 1 patient. Cyclosporin A (CsA) was used alone as first-line therapy for 3 patients. CsA in combination with steroids were administered in 13 patients. After 4 months treatment, 2 patients acquired complete response, 4 patients acquired partial response, the overall response was 35%. Conclusion: γδT-LGLL is a rare mature T-lymphocyte proliferative disease. Clinical and laboratory characteristics were quite similar for γδT-LGLL in compare with αβT-LGLL. γδT-LGLL predominantly expressed a CD4(-)/CD8(-) phenotype. The data presented here indicate the CsA is an effective option for the first-line treatment of γδT-LGLL.

Objective: To compare the consistency of thyroid stimulating hormone (TSH) results from four chemiluminescence assays. Methods: A total of 102 fresh serum samples from Peking Union Medical College Hospital during March 2018 and April 2018 were collected for precision evaluation and methodological comparison referring to CLSI EP15-A2 and EP9-A2 protocols. The levels of serum TSH were detected by Abbott i2000 (system A), Beckman DXI800 (system B), Siemens ADVIA Centaur XP (system C) and Roche e601 (system D) automatic chemiluminescence analyzers and their matching reagents, respectively. The obtained results were compared with the passing-bablok and Bland Altman methods. Taking 0.27 μIU/mL and 5.33 μIU/mL as the medical decision level, the expected bias of each detection system was compared. Results: The precisions of systems A,B,C and D were 1.7%-3.3%， 2.3%- 3.9%，0.7%-2.3% and 0.6%-1.5%,respectively. The median (P 25,P 75) of TSH concentrations detected by systems A,B,C and D were 1.898 (0.518,4.809)μIU/mL, 2.819 (0.719,7.020)μIU/mL,2.502 (0.692,6.888)μIU/mL and 3.105 (0.886, 7.905)μIU/mL, respectively. The coefficients of determination (R 2 ) of regression equation were above 0.975 for 4 detection systems. The correlation coefficients (r), intercepts and slopes of 4 detection systems were 0.993 5-0.997 1, 0-0.06 and 0.59-1.15, respectively, and systems B and C had the best correlations with 1.02 of slope and 0 of intercept. The deviation plot showed that the bias% of 4 detection systems was between -48.1% and 17.3%. Among them, systems A and D had the largest bias, while systems B and C had the lowest bias. The expected bias of 4 detection systems at the medical decision level was -40.7%-37.2%. Conclusion The consistency between Beckman and Siemens TSH detection systems is good, while those of Roche and Abbott TSH detection systems are different from the other two.

OBJECTIVE: To evaluate the efficacy and safety of salvianolate in elderly patients with unstable angina pectoris (UAP). METHODS: A prospective double-blind randomized placebo-controlled multicenter trial in elderly patients with UAP from 13 third-grade class-A hospitals in China was performed. A total of 318 patients were randomly allocated in a 1:1 ratio to an experimental group (160 patients) and a control group (158 patients). The experimental group was treated with salvianolate for 14 days on the basis of conventional medicine, and the control group was given a placebo for 14 days with the same criteria. Follow-up was lasted 28 days in both groups. The primary endpoint was biweekly frequency of angina pectoris attacks. The secondary endpoints included biweekly dosage of nitroglycerin, the Seattle Angina Questionnaire, angina pectoris severity and duration, myocardial injury markers, high-sensitivity C-reactive protein (hs-CRP) and N-terminal pro-B-type natriuretic peptide (NT-proBNP), as well as major adverse cardiovascular events (MACEs). Safety was assessed according to adverse events and serious adverse events. RESULTS: Baseline characteristics were similar between treatment groups. Compared with those in the control group, the frequency of biweekly angina attacks (2.92 vs . 4.08, P=0.025), the biweekly dosage of nitroglycerin, as well as the severity and duration of angina attacks (P<0.01) were reduced by salvianolate. The Seattle Angina Questionnaire score was also significantly improved in the experimental group than in the control group (P<0.05). No significant differences were observed between the two groups with respect to the incidence of MACEs. Salvianolate was well tolerated. CONCLUSIONS Salvianolate appear to have efficacy and well tolerated for elderly patients with UAP. [ClinicalTrials.gov identifier: NCT03037047].
