Objective To evaluate the therapeutic effect of CT/MRI image fusion and usual CT guided percutane-ous radiofrequency thermocoagulation of trigeminal semilunar ganglion.Methods The medical information of 88 patients diagnosed with primary trigeminal neuralgia were assembled.In accordance with different imaging guidance means,they were equally divided into the control group(trigeminal semilunar ganglion radiofrequency thermo-coagulation with CT guidance)and the fusion group(trigeminal semilunar ganglion radiofrequency thermocoagula-tion with assistance of CT/MRI image fusion technology)at random.The puncture time,intraoperative discomfort rate,preoperative,intraoperative and postoperative visual analogue scale(VAS)score,Barrow neurological insti-tute(BNI)pain score and postoperative complication rate were contrasted.Results The puncture operation time of the fusion group was shorter than that of the control group(P<0.05);the intraoperative and postoperative VAS and BNI scores,occurrence rate of intraoperative discomfort and postoperative complications in the fusion group were lower than those in the control group(P<0.05).Conclusion In respect of improving therapeutic effect and diminishing intraoperative discomfort and postoperative complications,CT/MRI image fusion technique is superior to CT guidance.

Objective:To analyze and compare the pathological data characteristics of patients with simple papillary thyroid carcinoma (PTC) and PTC combined with Hashimoto’s thyroiditis (HT), so as to provide clinical treatment ideas.Methods:A retrospective analysis was performed on the medical records of 326 PTC patients who met the requirements and underwent surgical treatment in the Department of Thyroid and Breast Surgery, Nanjing Hospital of Traditional Chinese Medicine from Jan. 2020 to May. 2022. There were 81 males and 245 females. They were divided into PTC group and HT-PTC group, according to whether they were combined with HT. Clinical data were collected and organized. The collection indicators included patient gender, age, body mass index (BMI), five preoperative thyroid function items including free triiodothyronine (FT3), free thyroxine (FT4), triiodothyronine (T3), thyroxine (T4), thyroid stimulating hormone (TSH), BRAF gene mutation, single or bilateral lesions, single or multiple lesions, largest postoperative pathological tumor lesions diameter, cervical lymph node metastasis (LNM) status, etc. At the same time, all patients were divided into CLNM group and no CLNM group according to CLNM status. The two groups were compared in terms of gender, age ≥55 years old, whether combined with HT, number of lesions, unilateral and bilateral, extraglandular invasion, microcarcinoma, and BRAF gene. Statistical software was used to analyze the results. t test, χ2 test, and logistic regression analysis were adopted. P<0.05 indicates that the difference is statistically significant. Results:The proportion of female patients in both groups was higher, and the proportion of female patients in the HT-PTC group (90/100, 90%) was higher than that in the PTC group (155/226, 69.59%). HT-PTC patients were younger than patients in the PTC group (43.03±12.72 vs. 43.70±12.63) years old, and their TSH (2.71±1.69 vs. 2.02±1.46) uIU/mL was higher. The differences were statistically significant (all P<0.05). There were no statistically significant differences in BMI, FT3, FT4, T3, or T4 (all P>0.05). The HT-PTC group had a lower proportion of BRAF gene mutations [87/100 (87%) vs. 212/226 (93.8%) ], a smaller maximum tumor diameter (1.06±0.73 vs. 1.32±0.97 cm), and a lower proportion of CLNM [37 /100 (37%) vs. 118/226 (52.2%) ]. The number of LNMs with metastasis is less (3.33±2.21 vs. 4.76±4.00), and it was more likely to be multifocal [44/100 (44%) vs. 73/226 (32.74%) ]. All differences were statistically significant (all P<0.05), and the differences in bilateral gland lobes involvement and extra-glandular invasion were not statistically significant. When accompanied by CLNM, gender (male vs. female) [55/100 (35.45%/64.52%) vs. 26/145 (15.2%/84.85%) ], age ≥ 55 years (yes vs. no) [21/134 (13.55) %/86.45%) vs. 50/121 (29.24%/70.76%) ], HT (yes vs. no) [37/118 (23.87%/76.13%) vs. 63/108 (36.84%/63.16%), number of lesions (single focus vs. multiple focus) [90/65 (41.94%/50.06%) vs. 119/52 (69.59%/30.41%) ], microcarcinoma (yes vs. no) [83/72 (53.55%/45.45%) vs. 139/32 (81.29%/18.71%) ] and extraglandular invasion (with vs. without) [38/117 (24.52%/75.48%) vs. 27/144 (17.42%/84.21%) ] had statistics significance (both P<0.05). There was no statistical significance in bilateral lesion involvement or BRAF gene mutation (all P>0.05). Multivariate logistic regression analysis showed that age, microcarcinoma, HT, gender, and number of lesions were independent risk factors for CLNM, and male gender and multifocal cancer were risk factors for CLNM. Age ≥55 years, microcarcinoma, and combined HT were negatively associated with CLNM. Conclusions:HT may promote the occurrence of PTC, but can inhibit its development. In the short term, patients with HT can have a better prognosis than those with simple PTC.

Objective:To investigate the safety and feasibility of endoscopic thyroidectomy by gasless trans subclavian approach (ETGTA) in treatment of papillary thyroid carcinoma (PTC) .Methods:The clinical data of 148 patients with PTC radical operation admitted to the Department of Thyroid and Breast Surgery, Nanjing Hospital of Traditional Chinese Medicine Affiliated to Nanjing University of Chinese Medicine from Jul. 2020 to May. 2022 were retrospectively analyzed. They were divided into subclavian approach group (53 cases) and modified miccoli group (95 cases) according to different surgical approaches. The operation time, intraoperative bleeding volume, postoperative drainage flow, postoperative drainage days, postoperative hospital stay, postoperative complications and cosmetic satisfaction were recorded in the 2 groups. Statistical software was used to analyze the results, including t test, Mann-Whitney U test, χ2 test, etc. P<0.05 was considered statistically significant. Results:There were no significant differences in age, sex ratio, maximum diameter, stage, tumor lesion or surgical method between the 2 groups ( P>0.05). The postoperative drainage days increased in the subclavian group than in the modified miccoli group (4.57±2.45 vs. 2.98±1.07) ( P<0.01), but there was no statistical difference in operation time, intraoperative blood loss, postoperative drainage, or postoperative hospital stay between the two groups ( P>0.05). The incidence of swallowing discomfort at 1 month [5.6% (3/53) vs. 18.9% (18/95), P=0.04] and 3 months [0% (0/53) vs. 7.4% (7/95) , P=0.04], anterior cervical area tightness or stiffness at 1 month [0% (0/53) vs. 11.6% (11/95), P=0.01] and 3 months [0% (0/53) vs. 8.4% (8/95), P=0.03] were less than that of the modified miccoli group, and the difference was statistically significant (4.1±0.7 vs. 2.4±0.8) ( P<0.01), and the cosmetic satisfaction of the subclavian approach was higher than that of the modified miccoli group ( P<0.01). There was no significant difference in postoperative temporary recurrent laryngeal nerve injury, postoperative 3d neck pain, postoperative hand-foot numbness or postoperative hematoma between the two groups (all P>0.05) . Conclusion:The radical resection of papillary thyroid carcinoma without inflatable subclavicular approach is safe and feasible, with few postoperative complications and better cosmetic effect, which is worth popularizing.

Gastric cancer is one of the most com-mon malignant tumors in the digestive system,which often occurs in middle-aged and elderly peo-ple.Traditional Chinese medicine recognizes gastric cancer as a kind of tumor characterized by fluid de-ficiency,heat accumulation and the growing bind-ing of toxins in the stomach.It is commonly treated with heat-clearing and detoxifying drugs in clinical practice.Hedyotis diffusa-Scutellaria barbata herb pair(HS)has the effects of clearing heat and detoxi-fying,promoting blood circulation,resolving car-buncle and expulsing boil,anti-inflammatory and analgesic,which are consistent with the etiology and pathogenesis of gastric cancer,therefore,it can be used for the treatment of gastric cancer.Modern pharmacological researches have con-firmed that HS can play an anti-gastric cancer role by inducing cell apoptosis,inhibiting cell prolifera-tion,inhibiting angiogenesis,improving immune mi-croenvironment and down-regulating telomerase activity.Herein,this review summarizes the active ingredients and related mechanism responsible for the anti-gastric cancer effect of HS,which will pro-vide the theoretical basis for its clinical use and the development of new drugs against gastric cancers.

Objective To explore the current situation and influencing factors that affect stroke specialist nurses in Henan Province and provide a reference for targeted interventions.Methods A total of 140 stroke specialist nurses from over 103 general hospitals in Henan Province were selected to participate the study with the convenience sampling method,between March and November 2022.General data questionnaire and the core competence evaluation questionnaire of stroke specialist nurses in Henan Province were employed for the investigation.Influencing factors were analysed by binary Logistic regression.Results A total of 134 specialist nurses responded to the survey.The findings revealed that the total score of core competence in the stroke specialist nurses was 279.5(257.0,306.0).Among the dimensions of core competence,the clinical thinking ability scored the highest at 4.4(4.0,4.9),while professional development ability scored the lowest at 3.7(3.4,4.0).Cluster analysis categorised that the scores＜250 were of a low score group(n=26)and those≥250 were of a high score group(n=108).Binary Logistic regression analysis indicated that education level,years working as a stroke specialist nurse,and the working experience in the stoke fast track team of A&E were the factors that influenced the core competence of the stroke specialist nurses in Henan Province(all P＜0.05).Conclusions This study has found that the core competence of stroke specialist nurses in Henan Province is at an acceptable level.Education,years working as a stroke specialist nurse and the working experience in the fast track team of A&E are the primary factors which influence core competence.Nursing managers should devise supportive programs to target the influencing factors and to improve the core competence of the stroke specialist nurses.

Objective:To investigate the effect of the transcription factor TBX1 on the proliferation of colorectal cancer cells and to explore potential molecular mechanisms.Methods:The mRNA and protein levels of TBX1 in colorectal cancer cell lines HCT116, RKO, SW480, HT29, and LOVO were detected by using reverse transcription quantitative real-time polymerase chain reaction (qRT-PCR) and Western blot. Colorectal cancer cell lines HCT116 and SW480 cells with low TBX1 expression were transfected with either a pcDNA3.1 plasmid containing TBX1 mimics (TBX1 overexpression group) or an empty pcDNA3.1 plasmid (the control group). LOVO cells with high TBX1 expression were transfected with small interfering RNA (siRNA) targeting TBX1 including si-TBX1-8604A, si-TBX1-8604B, and a negative control siRNA (si-NC), which were treated as si-TBX1-8604A group, si-TBX1-8604B group, and si-NC group. qRT-PCR was used to detect the expressions of transcriptional level TBX1 and PARK2, and Western blot was used to detect the protein levels of TBX1, PARK2, and key factors in the MAPK and PI3K signaling pathways. Methyl Thiazolyl Tetrazolium (MTT) assay and cell colony formation assay were used to detect the cell proliferation. Combining literatures and the JASPAR database, 2 binding sites of TBX1 in the PARK2 promoter region were predicted. Chromatin immunoprecipitation assay was employed to verify the binding sites of TBX1 to PARK2 in HCT116 and SW480 cells. Dual luciferase reporter gene assay was used to verify the targeting relationship between TBX1 and PARK2. The expression of TBX1 and PARK2 in colon cancer tissues was analyzed by using the Cancer Genome Atlas (TCGA) database (September 2023).Results:High TBX1 expression in HCT116 and SW480 cells transfected with TBX1 mimics plasmid was confirmed by qRT-PCR and Western blot, while TBX1 expression was successfully knocked down in LOVO cells transfected with siRNA targeting TBX1. MTT assay indicated that the absorbance values for HCT116 cells in TBX1 overexpression group on d1, d3, d5, and d7 after inoculation, and for SW480 cells on d3, d5, and d7 after inoculation were lower than those in the control group, and the differences were statistically significant (all P < 0.01). LOVO cells in the si-TBX1-8604A group and si-TBX1-8604B group exhibited higher absorbance values than the si-NC group on d1, d3, d5, and d7 after inoculation, and the differences were statistically significant (all P < 0.05). Cell colony formation assay revealed that after 14 d, the colony number of HCT116 cells [(387±9) vs. (843±13)] and SW480 cells [(413±9) vs. (931±15)] in TBX1 overexpression group was lower than that in the control group, and the differences were statistically significant (all P < 0.05). The colony number of LOVO cells in the si-TBX1-8604A group and si-TBX1-8604B group was (493±77) and (470±32), respectively, which was higher than that in the si-NC group (349±26), and the differences were statistically significant (all P < 0.05). The protein relative expression levels of p-ERK and p-AKT S473 in HCT116 and SW480 cells in TBX1 overexpression group were lower than those in the control group, while protein relative expression levels of p-ERK and p-AKT S473 in LOVO cells in the si-TBX1-8604A group and si-TBX1-8604B group were higher than those in the si-NC group, and the differences were statistically significant (all P < 0.05). The relative expression level of PARK2 mRNA in HCT116 and SW480 cells (all P < 0.01) and the protein level in the overexpression group were higher than those in the control group. Chromatin immunoprecipitation assay demonstrated that the enrichment times of TBX1 binding to 2 sites of PARK2 intron in HCT116 and SW480 cells in TBX1 overexpression group were higher than that in the control group, and the differences were statistically significant (all P < 0.05). Dual luciferase reporter gene assay showed that the relative luciferase activity of HCT116 and SW480 cells co-transfected with pcDNA3.1 plasmid containing TBX1 mimics and pGL3 plasmid containing PARK2 mimics was higher than that of cells co-transfected with empty pcDNA3.1 and pGL3 plasmids, co-transfected with empty pcDNA3.1 plasmid and pGL3 plasmid containing PARK2 mimics, co-transfected with pcDNA3.1 plasmid containing TBX1 mimics and empty pGL3 plasmid, and the differences were statistically significant (all P < 0.05). Spearman analysis showed that there was a positive correlation between transcriptional level TBX1 and PARK2 in colon cancer tissues (288 cases) in TCGA database ( r = 0.226, P < 0.001); and the relative expression level of PARK2 mRNA in colon cancer tissues (383 cases) was lower than that in normal intestinal tissues (50 cases), and the difference was statistically significant ( P < 0.001). Conclusions:Elevated expression of transcriptional factor TBX1 inhibits the proliferation of colorectal cancer cells, potentially by activating the downstream target gene PARK2 and inhibiting the phosphorylation of ERK and AKT in the MAPK and PI3K signaling pathways, ultimately affecting the activation of these pathways.
