OBJECTIVEThe aim of this paper was to investigate the factors associated with viral response and HBeAg seroconversion and the relationship between them at different stages of interferon treatment in HBeAg-positive chronic hepatitis B patients.

METHODSPEG-IFN alfa-2a was injected subcutaneously in doses of 180 microg once a week for 48 weeks to HBeAg-positive chronic hepatitis B patients, and the patients were followed for another 24 weeks after the treatment. The serum HBV DNA load was measured by real-time quantitative PCR assay. Microparticle enzyme immunoassay analysis (MEIA) was then carried out by an automatic enzyme immunoassay analysis instrument to measure HBeAg and anti-HBe. Virological response and HBeAg seroconversion rates, and the factors associated with them were analyzed.

RESULTSThe differences in ALT baselines between viral responding and non-responding groups were significant at treatment time and at the end of the follow-up period. These differences were also significant in patients with HBeAg seroconversion at 12 weeks and at the end of the follow-up period compared with the non-conversion group. No significant difference of HBV DNA baseline was observed between the HBeAg seroconversion and non-conversion group. At 12, 24 and 48 weeks, in patients with viral response during the treatment, their HBeAg seroconversion rates were 43.8%, 21.4% and 18.9% respectively; their respective HBeAg seroconversion rates remaining at 72 weeks were 42.9%, 33.3% and 27.6%. HBeAg seroconversion was related to HBV DNA negativity at 48 weeks treatment in the multivariate analysis (OR=2.15, 95.0% CI=1.744-2.664, P less than 0.01).

CONCLUSIONSViral response and early and sustained HBeAg seroconversion were associated with pretreatment ALT levels. HBeAg seroconversion was related to viral response during IFN treatment, but not to the baseline HBV DNA load.

Goiter is a kind of non-inflammatory and non-neoplastic hyperplasia and enlargement. Many studies have shown that substances such as thiocyanates and isothiocyanates can prevent the development of a variety of tumors. However, some studies have also found that such substances can lead to goiter. In this article, relevant information on common goitrogen in food are collected to explore their mechanism of action, laying a foundation for guiding residents to maintain a healthy and balanced diet.

This study is to investigate the protective effects of the SB203580 against radiation induced mortality and intestinal injury of mice. A total of 67 male C57BL/6 mice (20.0-22.0 g) were matched according to body weight and randomly assigned to one of three groups: control, total body irradiation exposure (IR, 7.2 Gy) only, and IR (7.2 Gy) + SB203580 (15 mg x kg(-1)). 30 days survival rate was observed in the experiment. In intestinal injury experiment, the expression levels of caspase-3, Ki67, p53 and p-p38 were assayed in the mice intestine crypts. The results showed that the 30 days survival rate was 100% (control), 0 (IR) and 40% (IR+ SB203580), separately. Compared to the IR groups, the positive cells of caspase-3, p53 and p-p38 in crypt cells decreased 33.00%, 21.78% and 34.63%, respectively. The rate of positive cells of Ki67 increased 37.96%. Significant difference was found between all of them (P < 0.01). SB203580 potently protected against radiation-induced lethal and intestinal injury in mice, and it may be a potential radio protector.

Angiogenesis inhibitors targeting the VEGF signaling pathway are developed into drugs for the treatment of vaious diseases, such as cancer, rheumatoid arthritis, and age-related macular degeneration. Recent studies have revealed that oleanolic acid (OA), a natural pentacyclic triterpenoid, inhibited the VEGF/VEGFR2 signaling pathway and angiogenesis in HUVECs, which may represent an attractive VEGF inhibitor. In this paper, rational structural modification towards OA was performed in order to improve its inhibitory effects aganist VEGF and anti-angiogenesis potential. As a result, a series of novel OA derivatives, possessing α,β-unsaturated ketone system in ring A and amide functional group at C-28, were prepared and evaluated for cytotoxicity and their ability to inhibit VEGF-induced abnormal proliferation of HUVECs. The results showed that two promising derivatives, OA-1 and OA-16, exhibited no in vitro cytotoxicity against HUVECs but showed more potent inhibitory activity against VEGF-induced proliferation and angiogenesis in HUVECs, compared with OA. The results of Western blot indicated that OA-1 and OA-16 inhibited VEGF-induced VEGFR2 activation. Furthermore, small interfering RNA experiments were performed to confirm that both compounds inhibited VEGF-induced angiogenesis via VEGFR2. Thus, the present study resulted in the discovery of new promising OA-inspired VEGF inhibitors, which can serve as potential lead compounds for the treatment of angiogenesis-related diseases.

Objective:To investigate the clinical characteristics of choledocholithiasis com-bined with periampullary diverticulum and influencing factor for difficult cannulation of endoscopic retrograde cholangiopancreatography (ERCP).Methods:The retrospective case-control study was conducted. The clinical data of 1 920 patients who underwent ERCP for choledocholithiasis in 15 medical centers, including the First Hospital of Lanzhou University, et al, from July 2015 to December 2017 were collected. There were 915 males and 1 005 females, aged (63±16)years. Of 1 920 patients, there were 228 cases with periampullary diverticulum and 1 692 cases without periampullary diverticulum. Observation indicators: (1) clinical characteristics of patients with choledocholithiasis; (2) intraoperative and postoperative situations of patients undergoing ERCP for choledocholithiasis; (3) influencing factor analysis for difficult cannulation in patients undergoing ERCP for choledocholithiasis. Measurement data with normal distribution were represented as Mean±SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M(range) or M( Q1, Q3), and com-parison between groups was conducted using the Wilcoxon rank sum test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test or Fisher exact probability. The Logistic regression model was used for univariate and multivariate analyses. Results:(1) Clinical characteristics of patients with choledocholithiasis. Age, body mass index, cases with complications as chronic obstructive pulmonary disease, diameter of common bile duct, cases with diameter of common bile duct as <8 mm, 8?12 mm, >12 mm, diameter of stone, cases with number of stones as single and multiple were (69±12)years, (23.3±3.0)kg/m 2, 16, (14±4)mm, 11, 95, 122, (12±4)mm, 89, 139 in patients with choledocholithiasis combined with periampullary diverticulum, versus (62±16)years, (23.8±2.8)kg/m 2, 67, (12±4)mm, 159, 892, 641, (10±4)mm, 817, 875 in patients with choledocholithiasis not combined with periampullary diver-ticulum, showing significant differences in the above indicators between the two groups ( t=?7.55, 2.45, χ2=4.54, t=?4.92, Z=4.66, t=?7.31, χ2=6.90, P<0.05). (2) Intraoperative and postoperative situations of patients undergoing ERCP for choledocholithiasis. The balloon expansion diameter, cases with intraoperative bleeding, cases with hemorrhage management of submucosal injection, hemostatic clip, spray hemostasis, electrocoagulation hemostasis and other treatment, cases with endoscopic plastic stent placement, cases with endoscopic nasal bile duct drainage, cases with mechanical lithotripsy, cases with stone complete clearing, cases with difficult cannulation, cases with delayed intubation, cases undergoing >5 times of cannulation attempts, cannulation time, X-ray exposure time, operation time were 10.0(range, 8.5?12.0)mm, 56, 6, 5, 43, 1, 1, 52, 177, 67, 201, 74, 38, 74, (7.4±3.1)minutes, (6±3)minutes, (46±19)minutes in patients with choledocholithiasis combined with periampullary diverticulum, versus 9.0(range, 8.0?11.0)mm, 243, 35, 14, 109, 73, 12, 230, 1 457, 167, 1 565, 395, 171, 395, (6.6±2.9)minutes, (6±5)minutes, (41±17)minutes in patients with choledocholithiasis not combined with periampullary diverticulum, showing significant differences in the above indicators between the two groups ( Z=6.31, χ2=15.90, 26.02, 13.61, 11.40, 71.51, 5.12, 9.04, 8.92, 9.04, t=?3.89, 2.67, ?3.61, P<0.05). (3) Influencing factor analysis for difficult cannulation in patients undergoing ERCP for choledocholithiasis. Results of multivariate analysis showed total bilirubin >30 umol/L, number of stones >1, combined with periampullary diverticulum were indepen-dent risk factors for difficult cannulation in patients with periampullary diverticulum who underwent ERCP for choledocholithiasis ( odds ratio=1.31, 1.48, 1.44, 95% confidence interval as 1.06?1.61, 1.20?1.84, 1.06?1.95, P<0.05). Results of further analysis showed that, of 1 920 patients undergoing ERCP for choledocholithiasis, the incidence of postoperative pancreatitis was 17.271%(81/469) and 8.132%(118/1 451) in the 469 cases with difficult cannulation and 1 451 cases without difficult cannula-tion, respectively, showing a significant difference between them ( χ2=31.86, P<0.05). In the 1 692 patients with choledocholithiasis not combined with periampullary diverticulum, the incidence of postopera-tive pancreatitis was 17.722%(70/395) and 8.250%(107/1 297) in 395 cases with difficult cannula-tion and 1 297 cases without difficult cannulation, respectively, showing a significant difference between them ( χ2=29.00, P<0.05). In the 228 patients with choledocholithiasis combined with peri-ampullary diverticulum, the incidence of postoperative pancreatitis was 14.865%(11/74) and 7.143%(11/154) in 74 cases with difficult cannulation and 154 cases without difficult cannulation, respectively, showing no significant difference between them ( χ2=3.42, P>0.05). Conclusions:Compared with patients with choledocholithiasis not combined with periampullary divertioulum, periampullary divertioulum often occurs in choledocholithiasis patients of elderly and low body mass index. The proportion of chronic obstructive pulmonary disease is high in choledocholithiasis patients with periampullary diverticulum, and the diameter of stone is large, the number of stone is more in these patients. Combined with periampullary diverticulum will increase the difficult of cannulation and the ratio of patient with mechanical lithotripsy, and reduce the ratio of patient with stone complete clearing without increasing postoperative complications of choledocholithiasis patients undergoing ERCP. Total bilirubin >30 μmol/L, number of stones >1, combined with periampullary diverticulum are independent risk factors for difficult cannulation in patients of periampullary diverticulum who underwent ERCP for choledocholithiasis.

Objective: To investigate the expression of glycoprotein non metastatic melanoma protein B (GPNMB) in renal eosinophilic tumors and to compare the value of GPNMB with CK20, CK7 and CD117 in the differential diagnosis of renal eosinophilic tumors. Methods: Traditional renal tumor eosinophil subtypes, including 22 cases of renal clear cell carcinoma eosinophil subtype (e-ccRCC), 19 cases of renal papillary cell carcinoma eosinophil subtype (e-papRCC), 17 cases of renal chromophobe cell carcinoma eosinophil subtype (e-chRCC), 12 cases of renal oncocytoma (RO) and emerging renal tumor types with eosinophil characteristics [3 cases of eosinophilic solid cystic renal cell carcinoma (ESC RCC), 3 cases of renal low-grade eosinophil tumor (LOT), 4 cases of fumarate hydratase-deficient renal cell carcinoma (FH-dRCC) and 5 cases of renal epithelioid angiomyolipoma (E-AML)], were collected at the Affiliated Drum Tower Hospital of Nanjing University Medical School from January 2017 to March 2022. The expression of GPNMB, CK20, CK7 and CD117 was detected by immunohistochemistry and statistically analyzed. Results: GPNMB was expressed in all emerging renal tumor types with eosinophil characteristics (ESC RCC, LOT, FH-dRCC) and E-AML, while the expression rates in traditional renal eosinophil subtypes e-papRCC, e-chRCC, e-ccRCC and RO were very low or zero (1/19, 1/17, 0/22 and 0/12, respectively); the expression rate of CK7 in LOT (3/3), e-chRCC (15/17), e-ccRCC (4/22), e-papRCC (2/19), ESC RCC (0/3), RO (4/12), E-AML(1/5), and FH-dRCC (2/4) variedly; the expression of CK20 was different in ESC RCC (3/3), LOT(3/3), e-chRCC(1/17), RO(9/12), e-papRCC(4/19), FH-dRCC(1/4), e-ccRCC(0/22) and E-AML(0/5), and so did that of CD117 in e-ccRCC(2/22), e-papRCC(1/19), e-chRCC(16/17), RO(10/12), ESC RCC(0/3), LOT(1/3), E-AML(2/5) and FH-dRCC(1/4). GPNMB had 100% sensitivity and 97.1% specificity in distinguishing E-AML and emerging renal tumor types (such as ESC RCC, LOT, FH-dRCC) from traditional renal tumor types (such as e-ccRCC, e-papRCC, e-chRCC, RO),respectively. Compared with CK7, CK20 and CD117 antibodies, GPNMB was more effective in the differential diagnosis (P<0.05). Conclusion: As a new renal tumor marker, GPNMB can effectively distinguish E-AML and emerging renal tumor types with eosinophil characteristics such as ESC RCC, LOT, FH-dRCC from traditional renal tumor eosinophil subtypes such as e-ccRCC, e-papRCC, e-chRCC and RO, which is helpful for the differential diagnosis of renal eosinophilic tumors.

Objective:To explore the effect of Huangjingwan （HW） on the expressions of Wnt/β-catenin signal pathway-associated proteins in the hippocampus of mice with Alzheimer's disease （AD） induced by D-galactose and okadaic acid with learning and memory disorders， as well as its mechanism. Method:After subcutaneous injection with 1.0% D-galactose （0.14 g·kg^-1·d^-1） into the back and neck of mice for 4 weeks， the right ventricle of mice was injected with 2 μL（75 ng） of okadaic acid for one time to make AD model， and the successfully modeled AD mice were selected by Morris water maze. Then， the selected AD mice were randomly divided into AD model group， memantine group （1.3×10^-3 g·kg^-1·d^-1） and HW group （2.5 g·kg^-1·d^-1）. In addition， the sham model control group and the normal control group were set up. At the same time， 2 μL normal saline was injected into the right ventricle of mouse in the sham model control group as the modeling control. Two weeks after molding， the mice in the two experimental drug groups were given the corresponding dose of the experimental drug by gavage for 4 weeks. In addition， after 2 weeks of AD modeling， mice in sham model control group and AD model group were intragastrically administrated with the same amount of normal saline daily for 4 weeks. There was no special treatment in the normal control group. At the end of gavage， the shuttle experiment was performed to detect the differences in learning and memory levels of mice in each group. The changes of β-catenin and GSK-3β positive neurons in CA1 area of hippocampus in each group were tested by immunohistochemistry. Quantitative real-time polymerase chain reaction （Real-time PCR） was used to measure the mRNA expressions of GSK-3β， β-catenin and CyclinD₁ in hippocampus of mice in each group. The Western blot was used to detect the expressions of total GSK-3β （t-GSK-3β）， phosphorylation of GSK-3β at Ser9 （p-Ser9-GSK-3β）， phosphorylation of GSK-3β at Tyr216 （p-Tyr216-GSK-3β）， total β-catenin （t-β-catenin）， phosphorylation of β-catenin （p-β-catenin） and CyclinD₁ proteins in hippocampus of mice in each group. Result:Compared with the normal control group， mice in AD model group showed an obvious dementia state， which was characterized by significant declines in learning and memory ability， the number of β-catenin immunoreactive neurons in hippocampal CA1 area， the mRNA and protein expressions of t-β-catenin and CyclinD₁， the protein expressions of p-Ser9-GSK-3β， and the ratio of p-Ser9-GSK-3β/t-GSK-3β and p-Tyr216-GSK-3β/t-GSK-3β in hippocampal region （P<0.01）， and significant increases in the number of GSK-3β immunoreactive neurons in hippocampal CA1 area， the mRNA and protein expressions of t-GSK-3β， the protein expressions of p-Tyr216-GSK-3β and p-β-catenin， the ratio of p-β-catenin/t-β-catenin in hippocampal region （P<0.01 respectively）. Compared with the AD model group， the dementia symptoms of mice in HW group were significantly alleviated， and the number of β-catenin immunoreactive neurons in hippocampal CA1 area， the mRNA and protein expressions of t-β-catenin and CyclinD₁， the protein level of p-Ser9-GSK-3β， the ratio of p-Ser9-GSK-3β/t-GSK-3β in hippocampal region were all significantly increased （P<0.01 respectively）， whereas the number of GSK-3β immunoreactive neurons in hippocampal CA1 area， the mRNA and protein expressions of t-GSK-3β， the proteins expressions of p-Tyr216-GSK-3β and p-β-catenin， the ratio of p-β-catenin/t-β-catenin in hippocampal region were all significantly decreased （P<0.01 respectively）， but the ratio of p-Tyr216-GSK-3β/t-GSK-3β has no significant statistical difference. Conclusion:HW shows the role of AD treatment， which can down-regulate the expression of GSK-3β in the hippocampus of AD mice and reduce its protein activity， and up-regulate the expression of β-catenin as well as increase its protein activity， so as to enhance the expression of downstream CyclinD₁ and promote the transcription of the target genes. Its mechanism may be related to the activation of Wnt/β-catenin signal pathway.
