Objective:To investigate the changes of thyroid hormones and the flow velocity of superior thyroid artery in patients with Graves' disease and Hashimoto's thyrotoxicosis before and after treatment with methimazole.Methods:A case-control study was conducted to select 45 cases of Graves' disease and 45 cases of Hashimoto's thyroiditis from October 2021 to December 2022 in the Department of Endocrinology, North China University of Science and Technology Affiliated Hospital. The changes of thyroid hormone and blood flow velocity of superior thyroid artery in patients with Graves' disease and Hashimoto's thyroiditis before and after treatment with methimazole were analyzed. Measurement data satisfying normal distribution were expressed by xˉ±s, and the mean between two groups was compared by t test. Measurement data not satisfying normal distribution were expressed by M( Q1, Q3), and the median between two groups was compared by Wilcoxon rank sum test. χ 2 test was used to compare the constituent ratio of enumeration data among groups. Results:There was no significant difference in thyroid stimulating hormone (TSH) between the two groups before treatment, and there was no significant difference in TSH between the two groups after 1 month and 3 months of treatment (all P>0.05). The levels of free triiodothyronine (FT3) were (24.09±9.29) pmol/L and (17.41±9.36) pmol/L in Graves' disease group and Hashimoto's thyroiditis group respectively before treatment. FT4 were (60.23±20.82) and (43.47±21.71) pmol/L, respectively, and the peak stolie vloiy (PSV) were (69.53±5.70) and (52.65±4.64) cm/s, respectively in Graves' disease group and Hashimoto's thyroiditis group respectively before treatment. There were significant differences between the two groups ( t values wrere 3.39 and 3.74, Z=13.83, all P<0.001). The difference of FT3 between one month after treatment and before treatment was (-6.36±5.32) and (-12.64±9.08) pmol/L ( t=4.02, P<0.001) and the difference in FT3 between 3 months of treatment and before treatment was (-10.14±9.50) and (-17.80±11.17) pmol/L, respectively ( t=3.51, P<0.001) between the Graves disease group and the Hashimoto's thyroiditis group. The difference in FT4 between the Graves disease group and the Hashimoto's thyroiditis group after 1 month of treatment and before treatment was (-28.47±10.09) and (-20.57±14.48) pmol/L ( t=7.01, P<0.001), and the difference of FT4 was (-47.06±20.57) and (-30.17±20.54) pmol/L ( t=3.91, P<0.001) between the Graves disease group and the Hashimoto toxin group. The difference between one month after treatment and before treatment was (-13.10(-34.10,-2.60)) and (-10.50(-27.5,-0.20)) cm/s ( Z=2.63, P=0.009), respectively. The difference between 3 months and before treatment was (-31.40(-53.20,-12.70)) and (-19.90(-46.00,-4.70)cm/s ( Z=4.40, P<0.001)) between the Graves disease group and the Hashimoto's thyroiditis group, and the difference was statistically significant. Conclusion:Thyroid hormone levels were decreased after treatment with methimazole in patients with diffuse toxic goiter and Hashimoto toxemia, but the difference was not statistically significant. The PSV level of superior thyroid artery in patients with diffuse toxic goiter was significantly lower than that in patients with Hashimoto's thyrotoxicosis.

Objective To explore the factors influencing enteral nutrition intolerance in critically ill patients and to develop a risk prediction model to provide medical staff with a tool for early identification of patient intolerance.Methods Domestic and international databases such as CNKI,PubMed and Web of Science were searched and supplemented by searching references and grey literature.The search period was from inception to November 2022.Data were independently screened and extracted by 2 systematically trained researchers,and the quality of the literature was evaluated.Meta-analysis was performed using Review Manager 5.4 software.The OR value of the comprehensive effect of the factors was taken as the coefficient of each factor in the formula,and the natural logarithm of the ratio of intolerance incidence and non-incidence was the constant term of the formula.From December 2022 to June 2023,360 patients who met the inclusion and exclusion criteria in the ICU of a tertiary hospital were collected as a model verification group by convenient sampling method,and the collected clinical data were substituted into the formula to evaluate the discrimination and calibration of the model.Results A total of 13 articles were included.7 influencing factors with more than 3 times of reports and statistically significant results were obtained.For age[OR=0.97,95％CI(0.94,0.99),P=0.010],Acute Physiology and Chronic Health Evaluation scoreⅡ[OR=1.17,95％CI(1.01,1.36),P=0.040],comorbidity with diabetes[OR=1.21,95％CI(1.05,1.40),P=0.008],comor-bidity with neurological diseases[OR=0.85,95％CI(0.74,0.98),P=0.020],mechanical ventilation[OR=3.21,95％CI(1.82,5.66),P＜0.001],using sedative analgesics[OR=2.27,95％CI(1.66,3.10),P＜0.001],using gastric motility drugs[OR=0.23,95％CI(0.15,0.36),P＜0.001].The incidence of enteral nutrition intolerance was 35.00％.The risk prediction model for enteral nutrition intolerance in critically ill patients was logit(P)=-0.619-0.031×age+0.157 × APACHE Ⅱ+0.191 ×comorbidity with diabetes-0.163 ×comorbidity with neurosurgery+0.820 ×using sedatives and analgesics+1.166×mechanical ventilation-1.470×using gastric dynamic drugs.The area under the receiver operating characteristic curve of the model was 0.864.The maximum Youden index was 0.589.The sensitivity was 0.922.The specificity was 0.667.The corresponding clinical diagnostic threshold was 0.536.Hosmer-Leme-show test x2=13.410,P=0.098.Brier score was 0.195.Conclusion The risk prediction model of enteral nutrition intolerance in critically ill patients based on large sample evidence-based medicine is universal,scientific and practical.It provides a tool for medical staff to identify patients with enteral nutrition feeding intolerance in ICU.

Based on the isolation and identification of Nosema ceranae(N.ceranae)in honeybees,this study optimized the synthesis method of nano-FeS derived from albumen and explored in vitro and in vivo antifungal effects against N.ceranae.Pathogens were isolated from infected honeybee colonies and identified as N.ceranae using morphological and molecular biology techniques.In vitro experiments were conducted to confirm the antifungal effects of nano-FeS against N.ceranae and elucidate the mechanism.In vivo experiments were carried out to validate the therapeutic effects of nano-FeS against N.ceranae infection.Nano-FeS was synthesized using the solvothermal method with an optimal scheme determined through orthogonal experiments,with an average par-ticle size of 75 nm.Flow cytometry and fluorescence staining experiments confirmed that nano-FeS induced apoptosis and necrosis in N.ceranae.After N.ceranae was exposed to nano-FeS,intracellu-lar iron accumulation,disruption of the glutathione and glutathione peroxidase antioxidant system,and subsequent ROS accumulation were observed,ultimately leading to lipid peroxidation of cell membranes.In vivo experiments demonstrated reduced mortality and decreased spore counts in the midgut of honeybees fed with nano-FeS.Transcriptome analysis and qPCR revealed the impact of nano-FeS on gene expression in the N.ceranae infected honeybee midgut.This study presented a promising alternative antifungal agent for N.ceranae infection in honeybees and elucidated the an-tifungal mechanism of nano-FeS related to ferroptosis.Additionally,the study found a positive cor-relation between the mass concentration of nano-FeS and its antifungal effectiveness against N.ceranae.

Objective To investigate the clinical efficacy and safety of 1 565 nm non-ablative fractional laser combined with topical minoxidil and oral finasteride in the treatment of patients with androgenetic alopecia(AGA).Methods Seventy-five male AGA patients with Norwood-Hamilton classification grade Ⅱ-Ⅲ,were randomly assigned into three groups:the control group 1,the control group 2 and the experimental group,with 25 cases in each group.Patients in the control group 1 received topical 5%minoxidil(1 mL,twice daily).Patients in the control group 2 were treated with both topical 5%minoxidil and oral finasteride(1 mg,once daily).Patients in the experimental group received a combined therapy of 1 565 nm non-ablative fractional laser in addition to topical 5%minoxidil and oral finasteride.Hair overall efficacy was evaluated using a 7-point rating scale after 24 weeks of treatment.Hair diameter and density were measured using a dermoscope.Patient satisfaction was assessed post-treatment,and adverse reactions were recorded.Results The overall efficacy of hair in the experimental group was superior to the control group 1 and the control group 2.There were no significant differences in hair density and hair diameter before treatment between the three groups(P＞0.05).After treatment,hair diameter and density increased in all three groups compared to baseline values(P＜0.05),and the hair diameter and hair density of the experimental group were higher than those of the control group 1 and the control group 2(P＜0.05).Patient satisfaction in the experimental group was higher than that in the control group 1 and the control group 2(P＜0.05).Patients in the experimental group experienced tolerable pain and burning sensations during laser treatment,and the symptoms were self-alleviated within a few hours.There were no serious adverse reactions reported in any group.Conclusion The combination therapy of 1 565 nm non-ablative fractional laser,5%minoxidil,and finasteride demonstrates significantly better efficacy in the treatment of AGA than minoxidil and finasteride alone drug therapy.

Objective:To observe and describe the clinicopathologic manifestations of acute kidney injury (AKI) caused by immune checkpoint inhibitors (ICIs).Methods:The clinicopathologic manifestations of patients diagnosed as AKI related to ICIs in Ningbo LiHuili Hospital during the period between December 2020 to December 2021 were retrospectively analyzed, including the primary tumor disease, renal pathological features, renal function progression and therapeutic effects.Results:A total of 6 patients were enrolled, all of whom were male, aged (62±11) years old. The median time from the application of ICIs to the onset of AKI was 46 d (ranging from 31 to 95 d). The median of the peak serum creatinine was 311 (205 to 1 053) μmol/L, and 1 patient received hemodialysis treatment. Six patients received renal biopsy, among which 4 cases were acute tubulointerstitial nephritis, 1 case of tubulointerstitial nephritis with both acute and chronic changes, 1 case of chronic tubulointerstitial nephritis. Of the 6 patients, 5 received glucocorticoid therapy, and 2 of the patients completely recovered, while 3 partially recovered. One patient didn′t use glucocorticoid, but his renal function was partially restored after stopping ICIs.Conclusions:AKI caused by ICIs is mainly manifested by acute tubulointerstitial nephritis. Glucocorticoid has some therapeutic effects on AKI caused by ICIs and may be an effective treatment.

Objective: To investigate the effect of triptolide, a specific inhibitor of heat shock protein 70 (HSP70), on apatinib resistance in gastric cancer cells line MKN45. Methods: The apatinib-resistant cells (MKN45/AR) and MKN45 parental cells were treated with apatinib, triptolide and apatinib combined with triptolide, respectively. CCK-8 assay was performed to determine the half maximal inhibitory concentration (IC₅₀) of MKN45/AR and MKN45 cells in the presence of different treatment. The mRNA expression of heat shock protein gene (HSPA1A and HSPA1B) was detected by RT-PCR, while the protein expression of heat shock protein 70 was analyzed using Western blot in MKN45/AR and MKN45 cells. Results: The IC₅₀ values of apatinib-sensitive and apatinib-resistant MKN45 cells were 10.411 μmol/L and 70.527 μmol/L, respectively, showing a significant difference (P<0.05). The mRNA expression of HSPA1A and HSPA1B in MKN45/AR cells was significantly higher than that in MKN45 cells (P<0.001). The protein expression of heat shock protein 70 was significantly decreased after 0.25 μmol/L triptolide treatment in MKN45/AR cells (P<0.01). When heat shock protein 70 was inhibited by triptolide, the IC₅₀ value of apatinib in MKN45/AR cells was reduced to 11.679 μmol/L, which was significantly lower than cells treated with apatinib alone (P<0.05). Conclusions The apatinib-resistant MKN45 cells have high levels of heat shock protein 70. Low doses of triptolide can significantly inhibit heat shock protein 70, leading to reverse the resistance phenotype of MKN45/AR cells. Therefore, inhibition of heat shock protein 70 provides a new therapy strategy for patients with apatinib resistance.

OBJECTIVESTo study the correlation between MRI apparent diffusion coefficient (ADC) and expression of Ki-67 in gastric cancers, and to investigate the application of ADC value in diagnosing the malignance of gastric cancer.

METHODSA retrospective cohort analysis was performed on 87 gastric cancer patients who received MRI examination and radical resection at Zhejiang Provincial Hospital of Traditional Chinese Medicine from November 2014 to August 2015. All the postoperative resected samples were confirmed as gastric cancer. Preoperative MRI examination was performed by using Siemens 3.0-T Verio MRI with following parameters: section thickness 3 mm, gap 1 mm, matrix 182×320, field of view 40 cm. Plain scan was followed by T1-weighted fat suppression technique VIBE 3D(TR3.92/TE1.39,90degree) scans at arterial phase (the 30th second), portal venous phase (the 60th second), lag period (the 90th second), axial planes and coronal planes (the 180th second), and sagittal planes (the 210th second), respectively. ADC value of tumor was measured at b-factor of 800 s/mmand ADC map was generated from DWI data on the work station. The expression of Ki-67 in cancer tissue was detected by routine immunohistochemical (SP) staining after surgery. Correlation between ADC value and the expression of Ki-67 in gastric cancer was analyzed.

RESULTSIrregular thickening of the gastric wall and inhomogeneous enhancement of the tumor after injection of the contrast material appeared in gastric cancer. Gastric cancer tissue presented hyperintensity and normal gastric wall presented isointensity in DWI image (b=800 s/mm). Compared with normal gastric tissue, mean ADC value of gastric cancer tissue was significant lower [(1.114±0.265)×10mm/s vs. (2.032±0.202)×10mm/s, t=26.209, P=0.000]. The ADC values of high-middle differentiation group, middle-low differentiation group, low differentiation group and signet ring cell carcinoma/mucinous adenocarcinoma group were (1.347±0.234)×10mm/s, (1.179±0.257)×10mm/s, (0.996±0.185)×10mm/s and (1.082±0.230)×10mm/s, respectively. The difference of mean ADC value among different tumor stages was significant(F=8.498, P=0.000). Along with the Ki-67 expression up-regulated, the ADC value decreased in cancer tissue. The Ki-67 expressions in cancer tissue was negatively correlated with cancer ADC values (r=-0.570, P=0.000). Furthermore, negative correlations of Ki-67 expressions with ADC values of high-middle differentiation group (r=-0.627, P=0.016), low differentiation group (r=-0.787, P=0.000) and signet ring cell carcinoma/mucinous adenocarcinoma group (r=-0.792, P=0.000) were observed respectively, while Ki-67 expression was not correlated with ADC value of middle-low differentiation group.

CONCLUSIONThe ADC value of gastric cancer can reflect the level of tumor differentiation, and is negatively correlated with Ki-67 expression in cancer tissues.
