Effects of the proliferation, migration and apoptosis of AHVAC - on gastric cancer MKN-28 cells / 中国临床药理学与治疗学

AIM: To investigate the effects of agkis-trodon halys venom anti-tumor component (AHVAC-) on the biological behavior of gastric cancer MKN-28 cells. METHODS: Gastric cancer MKN-28 cells were treated with the experimental concentrations (5, 10, 15 μg/mL) of AHAVC- for 24 h. Cell proliferation and toxicity assay (cell counting kit-8, CCK-8) was used to detect the inhibition rates of the cells in different concentrations of AHVAC-. The migration ability of the cells was evaluated by wound-healing and Transwell assay. The apoptosis were observed by laser confocal microscopy with annexin V-mCherry/DAPI double staining, and the apoptosis rates were analyzed by flow cytometry with annexin V-FITC/PI double fluorescence staining. The protein level of Caspease-3 was determined by Western blot. RESULTS: Compared with normal control group, the results of AHVAC- concentration groups showed that with the increase of AHVAC- concentration, the proliferative activity of MN-28 cells decreased gradually (P<0.01), the cell migration ability decreased gradually (P<0.01), and the cell apoptosis rate increased (P<0.05). The expression of apoptosis-related protein Caspease-3 was up-regulated (P<0.01). CONCLUSION: AHVAC- inhibits proliferation and migration of gastric cancer MSN-28 cells and induces apoptosis.

Expression and Clinical Significance of MKI67 in Pancreatic Cancer / 肿瘤防治研究

Objectives To explore the expression, biological function, and mechanism of MKI67 in pancreatic cancer and its clinical significance. Methods The expression level, diagnosis, and prognostic value of MKI67 in pancreatic cancer were analyzed using public databases. We also investigated the association between the MKI67 with immune cell infiltration and immune checkpoint molecules. We analyzed the functional pathway enrichment to uncover the possible molecular mechanisms. qRT-PCR and Western blot assay were used to verify the expression of MKI67 mRNA and protein. Immunohistochemistry staining was used to detect the expression of MKI67 in tissue protein. Results The high expression of MKI67 was significantly associated with high histological grades and poor outcomes in pancreatic cancer. High MKI67 expression was correlated with poor prognosis of pancreatic cancer patients (P=0.009). MKI67 was an independent risk factor for the patient outcome (95%CI: 1.084-1.743, P<0.05). The MKI67 expression was positively correlated with the helper T cell 2 levels but negatively correlated with plasmacytoid DC, NK cells, mast cells, the T follicular helper, immune DC, and CD8 T cells. Conclusion MKI67 may serve as a biomarker for the diagnosis and prognosis of pancreatic cancer and the mechanism might be associated with immune escape or immunosuppression.

Study on binocular and monocular accommodation in premyopia based on data integration pattern / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To compare the binocular and monocular accommodation among normal group, premyopia group and mild myopia group, and to study the characteristics of accommodation in the premyopia group, thus providing clinical evidence for the delay/prevention of myopia and the effective decrease of the incidence of myopia.METHODS: Cross-sectional descriptive study. A total of 179 children who had abnormal/high-risk visual acuity indicated by the vision screening in school from October 2021 to February 2023 were selected, including 92 males and 87 females, aged from 6 to 12(mean 8.55±1.66)years old, then they were referred to the Juvenile Myopia Prevention and Control Center in Cuizu Community Health Service Center. They were divided into normal group(+0.75 D&#x0026;#x003C;SE≤+2.00 D), the premyopia group(-0.50 D&#x0026;#x003C;SE≤+0.75 D)and the mild myopia group(-3.00 D≤SE≤-0.50 D)according to the diopters after cycloplegia, and binocular myopia grouping is defined by the eye with lower diopter. Binocular positive relative accommodation(PRA), negative relative accommodation(NRA), accommodative facility(AF), and monocular AF and amplitude of accommodation(AA)were examined. The age, binocular and monocular accommodation of different groups were compared.RESULTS: There were no difference in the sex ratio of different groups(χ2=0.167, P=0.920). There was no difference in age between the normal group and the premyopia group(P=0.310), but there were differences between the mild myopia group and the normal group and premyopia group(P=0.018, &#x0026;#x003C;0.01); Binocular NRA, PRA, and AF had significance between the normal group and the premyopia group(P&#x0026;#x003C;0.01), while there was no significance between the premyopia group and the mild myopia(P&#x0026;#x003E;0.05). Monocular AF had significance between the normal group and the premyopia group(P&#x0026;#x003C;0.01), while there was no significance between the premyopia group and the mild myopia group(P&#x0026;#x003E;0.05); The monocular AA had significance among the three groups(P&#x0026;#x003C;0.05).CONCLUSION: Although the diopters was normal, binocular NRA, PRA, monocular and binocular AF had significantly decreased in the premyopia group, and there was no significant difference compared with mild myopia group; monocular AA had decreased in the premyopia group and it was also significantly different from the mild myopia group. The accommodation function should be examined in premyopic children. Recovering the abnormal visual function through visual training may be a way to prevent and control premyopia from progressing to myopia.

Effects of different frequencies of pricking-bloodletting at auricular points plus auricular point sticking therapy on the serum levels of related factors in patients with acne vulgaris / 针灸推拿医学（英文版）

Objective: To observe the effects of different frequencies of pricking-bloodletting at auricular points plus auricular point sticking therapy on the levels of the serum immunoglobulin G (IgG), immunoglobulin M (IgM), testosterone (T), and insulin-like growth factor-1 (IGF-1) in patients with acne vulgaris (AV). Methods: Ninety patients with AV were randomly assigned to treatment group 1, treatment group 2, and treatment group 3 according to the random number remainder grouping method, with 30 cases in each group. All three groups received pricking-bloodletting at auricular points plus auricular point sticking therapy. Treatment group 1 was treated once a week, treatment group 2 was treated twice a week, and treatment group 3 was treated 3 times a week. Four-week treatment was taken as 1 treatment course, and 3 treatment courses were observed. On the day before the start of the study and on the day next to the end of each course, the global acne grading system (GAGS) score was recorded, and 3 mL of blood from the median cubital vein was collected to test the serum levels of IgG, IgM, T, and IGF-1. After 3 courses of treatment, the efficacy index was calculated according to the GAGS score, and the serum indicators in patients with effective treatment (efficacy index ≥20％) and complete sampling were analyzed. Results: A total of 60 patients were included in the final blood indicator analysis. After 3 courses of treatment, the intra-group comparisons showed that the serum IgG level increased significantly in patients in treatment group 1 (P<0.01); the serum T level decreased significantly in the female patients in treatment group 2 (P<0.05); the IGF-1 level significantly decreased in the patients in all three groups (P<0.05 or P<0.01). There were no significant differences in the serum levels of IgG, IgM, T, and IGF-1 among the three groups at each time point (P>0.05). Conclusion: Pricking-bloodletting at auricular points plus auricular point sticking therapy can affect the levels of serum IgG, T, and IGF-1 in AV patients. The level of the serum IGF-1 can be reduced by treatment once a week, twice a week, or 3 times a week. Treatment once a week can increase the patients' serum IgG level, and treatment twice a week can significantly decrease the serum T level in female patients. Reducing the serum IGF-1 level may be one of the action mechanisms of pricking-bloodletting at auricular points plus auricular point sticking therapy in treating AV.

Analysis of medical quality in psychiatric hospitals based on DRG evaluation / 中华医院管理杂志

Objective:To evaluate the medical service quality of psychiatric hospitals in Beijing based on diagnostic related group (DRG), analyze the evaluation effect, for refences to constructe a DRG performance evaluation system suitable for psychiatric hospitals.Methods:This study extracted data such as the number of DRG groups, etc. of hospitalized patients in 14 tertiary and secondary psychiatric hospitals in Beijing from 2018 to 2020 from the Beijing inpatient medical performance evaluation platform, and analyzed data on DRG performance evaluation indicators, as well as the average length of hospital stay and average cost of DRG enrolled cases. All data were analyzed using descriptive research methods, and inter group comparisons were conducted using the Mann Whitney U-test. Results:From 2018 to 2020, the average number of DRG groups in tertiary hospitals (28) was higher than that in secondary hospitals (10) ( P<0.05), and the average CMI values of both were the same(1.79); The average cost consumption index (1.15) of tertiary hospitals was higher than that of secondary hospitals (0.65) ( P<0.05), while the average time consumption index (1.11) was slightly lower than that of secondary hospitals (1.30); The mortality rate of the low-risk group in tertiary hospitals (0.01%) was generally lower than that in secondary hospitals (0.88%), and the average percentage of DRG admitted inpatients (82.8%) was significantly higher than that in secondary hospitals (27.3%) ( P>0.05). The average length of stay and cost per case for DRG enrolled inpatients in tertiary and secondary hospitals were lower than the overall hospital discharge cases ( P<0.05). Conclusions:The number of DRG groups, CMI value, and low-risk mortality rate could be used for evaluating the medical service capacity and safety of psychiatric hospitals, but the cost and time consumption index could not objectively reflect the efficiency of hospital medical services. DRG performance evaluation indicators are more suitable for evaluating short-term hospitalization of psychiatric patients. The proportion of DRG enrolled cases might be a potential indicator for evaluating the service quality of psychiatric hospitals.

Effect and necessity of early surgical management of neonatal testicular torsion: an analysis of 11 cases / 中华围产医学杂志

Objective:To investigate the clinical features of neonatal testicular torsion and to evaluate the effect and necessity of early intervention.Methods:A retrospective analysis was performed on 11 neonates admitted to the Second Hospital of Shandong University with neonatal testicular torsion from June 2017 to June 2022. Clinical data of these cases including clinical manifestations, ultrasonography findings, surgical management and outcomes were reviewed and analyzed with descriptive statistical methods.Results:The median age of the 11 patients on admission was 2.6 d (1-5 d). The median time from finding abnormal scrotum to admission was 12 h (1-120 h). Various degrees of scrotal swelling or scleroma were found in the patients. Among them, seven patients presented with acute inflammatory signs of cyano sis or skin redness, and testis-like tissue induration could be touched. Ultrasound scan showed abnormal blood flow in the affected testicle in all cases. Emergency scrotal exploration under general anesthesia was performed successfully in all cases and ten of them underwent orchiectomy of the affected testicle plus contralateral orchiopexy. The rest one who was admitted within 1 h after birth only underwent orchiopexy of the affected testicle as the parents refused contralateral testicular exploration. During the operation, 12 twisted testis were observed, including seven with extravaginal torsion, three with intravaginal torsion and two adhering to the surrounding tissue without normal testicular tissue or distinguishable torsion direction or degree. In this study, ten patients had unilateral testicular torsion, which affected the left side in seven cases and the right side in three cases, and one had bilateral testicular torsion, which was diagnosed as left testicle torsion before surgery. During scrotal exploration, the left testicle of this bilateral case was resected due to necrosis, while the right testicle twisted about 180 degrees with good blood flow and was subjected to orchidopexy after reduction. In one case, the unaffected testicle was unfixed and dysplastic during contralateral exploration, which was also subjected to orchidopexy. In the 12 testis with torsion, one testicle of the patient admitted within 1 h after birth and the right testicle of the bilateral case were preserved with a salvage rate of 2/12. Pathological examination showed necrosis in the ten excised testis, and fibrosis and calcification foci in two of them. None of the patients had any perioperative complications and the scrotal incision healed well in all neonates. The patients were followed up for 6-12 months with regular ultrasound. The two preserved testis and the contralateral testis subjected to orchidopexy were located in the scrotum with good blood supply, and no torsion, atrophy or other abnormalities occurred.Conclusions:Neonatal testicular torsion is rarely seen in clinical practice and has no specific manifestations. It has a high excision rate due to testicular necrosis. Early diagnosis and bilateral scrotal exploration are crucial to the prognosis and the keys to save the affected testis and avoid anorchidism.

Clinical application and effectiveness of patellar tunnel locator in medial patellofemoral ligament reconstruction surgery / 中国修复重建外科杂志

OBJECTIVE@#To evaluate the operability and effectiveness of a self-developed patellar bone canal locator (hereinafter referred to as "locator") in the reconstruction of the medial patellofemoral ligament (MPFL).@*METHODS@#A total of 38 patients with recurrent patellar dislocation who met the selection criteria admitted between January 2022 and December 2022 were randomly divided into study group (the patellar canal was established with a locator during MPFL reconstruction) and control group (no locator was used in MPFL reconstruction), with 19 cases in each group. There was no significant difference in baseline data between the two groups ( P>0.05), such as gender, age, body mass index, disease duration, patella Wiberg classification, constituent ratio of cartilage injury, Caton index, tibia tubercle-trochlear groove, and preoperative Lysholm score, Kujal score, Tegner score, visual analogue scale (VAS) score, and so on. The Lysholm score, Kujal score, Tegner score, and VAS score were used to evaluate knee joint function before operation and at 3 days,1 month, 3 months, and 6 months after operation. The ideal prepatellar cortical thickness and canal length were measured before operation, and the actual prepatellar cortical thickness and canal length after operation were also measured, and D1 (the distance between the ideal entrance and the actual entrance), D2 (the ideal canal length minus the actual canal length), D3 (the ideal prepatellar cortical thickness minus the actual prepatellar cortical thickness) were calculated.@*RESULTS@#Patients in both groups were followed up 6-8 months (mean, 6.7 months). The incision length and intraoperative blood loss in the study group were smaller than those in the control group, but the operation time was longer than that in the control group, the differences were significant ( P<0.05). There was no complication such as incision infection, effusion, and delayed healing in both groups, and no further dislocation occurred during follow-up. One patient in the study group had persistent pain in the anserine area after operation, and the symptoms were relieved after physiotherapy. The VAS score of the two groups increased significantly at 3 days after operation, and gradually decreased with the extension of time; the change trends of Lysholm score, Kujal score, and Tegner score were opposite to VAS score. Except that the Lysholm score and Kujal score of the study group were higher than those of the control group at 3 days after operation, and the VAS score of the study group was lower than that of the control group at 3 days and 1 month after operation, the differences were significant ( P<0.05), there was no significant difference in the scores between the two groups at other time points ( P>0.05). Patellar bone canal evaluation showed that there was no significant difference in preoperative simulated ideal canal length, prepatellar cortical thickness, and postoperative actual canal length between the two groups ( P>0.05). The postoperative actual prepatellar cortical thickness of the study group was significantly smaller than that of the control group ( P<0.05). D1 and D3 in the study group were significantly higher than those in control group ( P<0.05), but there was no significant difference in D2 between the two groups ( P>0.05).@*CONCLUSION@#The locator can improve the accuracy of MPFL reconstruction surgery, reduce the possibility of intraoperative damage to the articular surface of patella and postoperative patellar fractures.

Characteristics of allergen component in dust mite-induced allergic rhinitis patients / 临床耳鼻咽喉头颈外科杂志

Objective:To investigate the characteristics of allergen component in dust mite（DM） -induced allergic rhinitis（AR） patients, and provide reference for the diagnosis and treatment of AR. Methods:DM-induced AR patients with or without allergic asthma（AA） who visited the Allergy Department of Tongji Hospital, Huazhong University of Science and Technology between 2021 and 2022 were enrolled. Patients'age, gender, and visual analog scale（VAS） for symptoms were recorded. sIgE and sIgG4 levels of allergen components such as Der f1, Der f2, Der p1, Der p2, Der p7, Der p10, Der p21, and Der p23 were detected using a protein chip method. The sensitization characteristics of the allergen components in the patients were observed, and the correlation between sIgE, sIgG of each component and VAS as well as the component differences between AR and AR with AA（AR&AA） were evaluated. Results:A total of 87 DM-induced AR patients were enrolled, with 42.5% of them were AR&AA, their VAS scores were significantly higher than those of AR patients（6.38±1.95 vs 5.25±1.85, P=0.009 8）. The order of sensitization rates for DM components was as follows: Der p2（82.8%）, Der f2（81.6%）, Der p1（74.7%）, Der f1（70.1%）, and Der p23（35.6%）. The order of positive rates for sIgG4 was: Der p2（21.8%）, Der f2（13.8%）, Der p21（8.0%）, and Der p7（6.9%）. There were no correlation between the sIgE, sIgG4 levels or positive numbers of components and VAS scores, but there were positive correlations between sIgE, sIgG4 concentrations of components. Compared with AR patients, AR&AA patients had higher levels of sIgE for Der p（60.5[7.2-91.1]vs 14.0[4.8-45.1], P=0.02）, Der f（49.8[15.7-81.6]vs 21.3[7.0-50.2], P=0.04）, Der p1（27.2[0.7-51.5]vs 2.6[0.2-24.9], P=0.02）, Der p2（20.0[1.4-60.6]vs 5.5[0.6-19.1], P=0.004）, and Der f2（58.9[16.0-89.2]vs 23.4[0.9-56.8], P=0.009）, and a higher proportion of AR with AA patients had sIgE levels of Der p1（70.3% vs 48.0%, P=0.038） and Der p23（27.0% vs 14.0%, P=0.039） that were ≥3 grades. Conclusion:Der p1/f1, Der p2/f3, and Der p23 are the major components of DM sensitized AR patients. Multiple component sensitization and sIgE, sIgG4 levels of each component are not correlated with the severity of AR. The sIgE levels of the Der p1/f1, Der p2/f3, and Der p23 components in AR&AA patients are higher than AR.

Double-negative T cells: a promising avenue of adoptive cell therapy in transplant oncology / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

Tumor recurrence is one of the major life-threatening complications after liver transplantation for liver cancer. In addition to the common mechanisms underlying tumor recurrence, another unavoidable problem is that the immunosuppressive therapeutic regimen after transplantation could promote tumor recurrence and metastasis. Transplant oncology is an emerging field that addresses oncological challenges in transplantation. In this context, a comprehensive therapeutic management approach is required to balance the anti-tumor treatment and immunosuppressive status of recipients. Double-negative T cells (DNTs) are a cluster of heterogeneous cells mainly consisting of two subsets stratified by T cell receptor (TCR) type. Among them, TCRαβ+ DNTs are considered to induce immune suppression in immune-mediated diseases, while TCRγδ+ DNTs are widely recognized as tumor killers. As a composite cell therapy, healthy donor-derived DNTs can be propagated to therapeutic numbers in vitro and applied for the treatment of several malignancies without impairing normal tissues or being rejected by the host. In this work, we summarized the biological characteristics and functions of DNTs in oncology, immunology, and transplantation. Based on the multiple roles of DNTs, we propose that a new balance could be achieved in liver transplant oncology using them as an off-the-shelf adoptive cell therapy (ACT).

Study on environmental residues detection and cleaning method of 15 cytotoxic antineoplastic drugs in PIVAS of our hospital / 中国药房

OBJECTIVE To provide a method to reduce environmental residues for pharmacy intravenous admixture service （PIVAS）， and ensure the occupational health of medical staff. METHODS The residues of 15 cytotoxic antineoplastic drugs such as gemcitabine were detected by UPLC-Q-Orbitrap-HRMS. The cleaning process was optimized with the residual quantity as the index. Nitrogen blowing method was used for alcohol volatilization experiment. CCK-8 assay was used to detect the effect of chlorine-containing disinfectant on the toxicity of cytotoxic antitumor drugs. RESULTS The linear range of 15 cytotoxic antineoplastic drugs such as gemcitabine were 0.5-1 000 ng/mL. RSDs of intra-day and intra-day precision were no higher than 20.00%. Six drugs including gemcitabine， isocyclophosphamide and cyclophosphamide were detected in the PIVAS environment of our hospital， and the residue of cyclophosphamide was relatively high. The optimal cleaning procedure was cleaning once with water + cleaning once with 1 000 mg/L chlorine-containing disinfectant + cleaning once with 75% alcohol， wiping with dry gauze method. The results of alcohol volatilization test showed that there was no significant difference in drug residues between control group and 75% alcohol group （P＞0.05）. The results of CCK-8 test showed that compared with control group， the survival rates of the cells treated with 15 cytotoxic antineoplastic drugs were decreased significantly （P＜0.01）； the survival rates of the cells treated with 15 cytotoxic antineoplastic drugs+chlorine-containing disinfectant were significantly higher than those treated with 15 cytotoxic antineoplastic drugs （P＜0.01）. CONCLUSIONS A method for the simultaneous determination for residues of 15 cytotoxic antineoplastic drugs such as gemcitabine in PIVAS is successfully established； the optimal cleaning procedure can significantly reduce the residues of drugs， the use of chlorine- containing disinfectant can significantly reduce the toxicity of drug， and the residual drugs will not cause secondary contamination of the operating area with alcohol volatilization.

Mechanisms of Euphorbia fischeriana steud. alcohol extracts intreatment of HCC based on network pharmacology and experiment verification / 中国药理学通报

Aim To investigate the molecular mechanisms of alcohol extracts of Euphorbia fischeriana steud. against hepatocellular carcinoma (HCC) through a combination of network pharmacology analysis and experimental validation. Methods The active ingredients and targets of alcohol extracts of Euphorbia fischeriana steud. were determined through TCMSP, Swiss ADME, Swiss Target Prediction database and references. The databases DisGeNET and GeneCards were employed to screen potential HCC-related genes. Venny platform, STRING platform and Cytoscape software were applied to construct active ingredient-target-disease and protein-protein interaction (PPI) network maps. Gene ontology (GO) and kyoto encyclopedia of genes and genomes (KEGG) enrichment analyses were performed using the DAVID database. To assess the effects of Euphorbia fischeriana steud. alcohol extracts on BEL-7402 cells, the proliferation and apoptosis were detected by CCK-8, EdU and flow cytometry assays, and the related protein levels of JAK2/STAT3 pathway were analyzed by Western blot. Additionally, H22 hepatocellular carcinoma mouse model was used to evaluate the in vivo efficacy of Euphorbia fischeriana steud. alcohol extracts. Results A total of 916 HCC targeted genes, 30 active ingredients containing the related 567 potential targeted genes, and 115 intersection targets of disease and compounds were obtained. KEGG enrichment analysis identified JAK2/STAT3 signaling as a critical pathway. In vitro experiments showed the alcohol extracts of Euphorbia fischeriana steud. could inhibit proliferation, promote apoptosis and suppress JAK2/STAT3 signaling pathway in a dose-dependent manner in BEL-7402 cells. In addition, the alcohol extracts of Euphorbia fischeriana steud., either alone or in combination with sorafenib, dramatically blocked tumor growth in in vivo tests. Conclusions Euphorbia fischeriana steud. alcohol extracts have anti-cancer effects in HCC, and the molecular mechanisms may be connected to the regulation of JAK2/STAT3 signaling pathway.

Analysis on the spectrum characteristics of noise hazards in metal products industry / 中国职业医学

{L-End}Objective To analyze the spectrum characteristics of noise hazards in the metal products industry. {L-End}Methods A total of six metal product industries were selected as research subjects using stratified sampling method. The noise intensity (A/C-weighted) and noise spectrum (Z-weighted) of workplaces and job positions were detected. The characteristics of the noise spectrum of each job position were analyzed using the difference between equivalent continuous C-weighted sound pressure level (LCeq)-equivalent continuous A-weighted sound pressure level (LAeq), the dominant frequency of the noise spectrum, and cluster analysis methods. {L-End}Results The workplace noise and job position noise of 11 main noise positions in the metal products industry were exceeded national standard, with incidence of 69.2% and 78.1%, respectively. The average of normalization of equivalent continuous A-weighted sound pressure level to a normal 40 hours working week exceeded the national standard in 100.0% of hydraulic workers, welders, and ultrasonic cleaning workers. The result of spectrum analysis showed that the noise in the metal product industry was mainly broadband. The noise of the collision welder position was classified as low-frequency broadband noise, while the noise of the painter position was classified as low-frequency narrowband noise. The noise spectrum characteristics of other positions were similar and classified into one category, all of which were broadband noise. Among them, numerical control lathe workers, welders, threaders, machinists, and cutters were exposed to high-frequency broadband noise, while press workers were exposed to mid-frequency broadband noise, and grinders, hydraulic workers, and ultrasonic cleaning workers were exposed to low-frequency broadband noise. The detection rate of binaural high-frequency hearing threshold improvement among workers was 61.7%, and there was no statistical correlation between the detection rate of binaural high-frequency hearing threshold improvement and the noise level intensity of each spectrum. {L-End}Conclusion The level of noise hazards in the metal products industry is severe. Effective engineering control measures and hearing protection measures should be implemented based on the spectral characteristics of noises.

Expression of MSI1 and HER2 in mammary Paget's disease and their correlation with clinicopathological features and prognosis / 中华病理学杂志

Objective: To investigate the expression of MSI1 and HER2 in mammary Paget's disease, and the correlation between the expression levels of MSI1 and HER2 and the clinicopathologic characteristics and prognosis of the patients. Methods: Clinical data and paraffin-embedded specimens of 34 pairs of mammary Paget's disease and underlying breast cancer were collected at the Department of Pathology, Affiliated Lianyungang Oriental Hospital of Xuzhou Medical University from March 2011 to December 2019. Immunohistochemistry was used to detect the expression of MSI1 and HER2 in mammary Paget's disease and the accompanying breast cancer, and to analyze the correlation between the expression levels of MSI1 and HER2 and their clinicopathologic features, as well as their influence on prognosis. Results: In mammary Paget's disease, the positive rate of MSI1 was 91.2% (31/34) and the positive rate of HER2 was 88.2% (30/34); the expression of MSI1 and HER2 was positively correlated (P=0.001, r=0.530). The expression of MSI1 was positively correlated with menopausal status (r=0.372, P=0.030) and lymph node metastasis (r=0.450, P=0.008). HER2 expression was positively correlated with menopausal status (r=0.436, P=0.010), and negatively correlated with ER expression (r=-0.365, P=0.034). The co-expression of MSI1 and HER2 was positively correlated with age (r=0.347, P=0.044) and menopausal status (r=0.496, P=0.003), and negatively correlated with ER expression (r=-0.461, P=0.006). Conclusions: MSI1 and HER2 are highly expressed in mammary Paget's disease and their expression levels are positively correlated. The correlation analysis between clinicopathological features and prognosis suggests that both of them may be involved in the occurrence and development of mammary Paget's disease and are potential therapeutic targets for mammary Paget's disease.

Effect of moxibustion on ureteral stent-related symptoms after ureteroscopic lithotripsy / 中国针灸

OBJECTIVES@#To observe the clinical efficacy of moxibustion combined with western medication on ureteral stent-related symptoms after ureteroscopic lithotripsy (URL).@*METHODS@#One hundred and fifty patients with upper urinary tract calculus implanted with ureteral stents after URL were randomly divided into a moxibustion group (50 cases, 1 case dropped out), a placebo moxibustion group (50 cases, 3 cases dropped out) and a blank control group (50 cases). No intervention was performed in the blank control group. On the basis of oral administration with tamsulosin hydrochloride sustained release capsule (starting from the first day after surgery, once a day, 0.2 mg each time, continuously for 4 weeks), in the moxibustion group, moxibustion was operated at Guanyuan (CV 4) and bilateral Shenshu (BL 23); the sham-moxibustion was delivered at the same acupoints in the placebo moxibustion group, once daily, 6 times a week, for 15 min in each treatment. The duration of treatment was 4 weeks. Before treatment, and after 1, 2 and 4 weeks of treatment, the scores of lower urinary tract symptoms, body pain, general health, work performance and satisfaction of sexual matters were compared among the 3 groups. The tract calculus clearance rate, urinary infection and the oral administration of painkillers were compared after 4 weeks of treatment in the 3 groups.@*RESULTS@#The scores of lower urinary tract symptoms, body pain and general health after 1 week of treatment, and the scores of lower urinary tract symptoms, body pain, general health and work performance after 2 and 4 weeks of treatment were lower than those before treatment in the 3 groups (P<0.01). The scores of lower urinary tract symptoms and body pain in the moxibustion group after 1, 2 and 4 weeks of treatment were lower than those in the blank control group and the placebo moxibustion group (P<0.01, P<0.05) respectively. The score of general health in the moxibustion group was lower than that in the blank control group after 1 week of treatment (P<0.01), and lower than those of the blank control group and the placebo moxibustion group after 2 and 4 weeks of treatment (P<0.01, P<0.05). Regarding the score of work performance, it was lower in the moxibustion group after 1 and 2 weeks of treatment compared with those in the blank control group (P<0.05, P<0.01), and lower than those of the blank control group and the placebo moxibustion group after 4 weeks of treatment (P<0.01, P<0.05). The tract calculus clearance rate in the moxibustion group was 95.9% (47/49), higher than that in the blank control group (80.0%, 40/50, P<0.05). The proportion of oral administration of painkillers in the moxibustion group (28.6%, 14/49) and the placebo moxibustion group (40.4%, 19/47) was lower than that in the blank control group (76.0%, 38/50, P<0.01) respectively.@*CONCLUSIONS@#Moxibustion combined with western medication relieves lower urinary tract symptoms and body pain, and accelerate the recovery of general health and work performance in the patients after URL.
