Research trends in lung cancer and the tumor microenvironment: a bibliometric analysis of studies published from 2014 to 2023.

Background: Lung cancer (LC) is one of the most common malignant tumors in the world and the leading cause of cancer-related deaths, which seriously threatens human life and health as well as brings a heavy burden to the society. In recent years, the tumor microenvironment (TME) has become an emerging research field and hotspot affecting tumor pathogenesis and therapeutic approaches. However, to date, there has been no bibliometric analysis of lung cancer and the tumor microenvironment from 2014 to 2023.This study aims to comprehensively summarize the current situation and development trends in the field from a bibliometric perspective. Methods: The publications about lung cancer and the tumor microenvironment from 2014 to 2023 were extracted from the Web of Science Core Collection (WoSCC). The Microsoft Excel, Origin, R-bibliometrix, CiteSpace, and VOSviewer software are comprehensively used to scientifically analyze the data. Results: Totally, 763 publications were identified in this study. A rapid increase in the number of publications was observed after 2018. More than 400 organizations published these publications in 36 countries or regions. China and the United States have significant influence in this field. Zhou, CC and Frontiers in Immunology are the most productive authors and journals respectively. Besides, the most frequently cited references were those on lung cancer pathogenesis, clinical trials, and treatment modalities. It suggests that novel lung cancer treatment models mainly based on the TME components, such as cancer-associated fibroblasts (CAFs) may lead to future research trends. Conclusions: The field of lung cancer and the tumor microenvironment research is still in the beginning stages. Gene expression, molecular pathways, therapeutic modalities, and novel detection technologies in this field have been widely studied by researchers. This is the first bibliometric study to comprehensively summarize the research trend and development regarding lung cancer and tumor microenvironment over the last decade. The result of our research provides the updated perspective for scholars to understand the key information and cutting-edge hotspots in this field, as well as to identify future research directions.

The imaging dynamic changes in the malignant transformation of an epidermoid cyst: a case report and literature review.

Malignant transformation of epidermoid cysts is a rare complication. Most of the previously reported cases have involved postoperative malignant transformations. We present a case of malignant transformation of a nonpostoperative epidermoid tumor into squamous cell carcinoma (SCC) that occurred in a 61-year-old Chinese woman. The patient's initial cranial MRI scan showed an epidermoid cyst with marginal enhancement in the pre-pontine cistern, and the lesion gradually enlarged after 10 months. A craniotomy was performed using to remove part of the tumor via the right retrosigmoid approach, and postoperative pathology confirmed that the transformation of the epidermoid cyst was malignant. Our case study suggests that the possibility of malignant transformation of epidermoid cyst should not be ignored on the basis of enhanced imaging features, regardless of whether they are nodular, annular, or patchy, as is the case for inflammation. Strict follow-up is required for early detection of malignant transformation to prompt correspondingly early clinical treatment.

Benefit-finding experiences of cervical cancer survivors in rural Yunnan province, China: A qualitative study.

AIM: To explore and describe cervical cancer patients' benefit-finding experiences in rural China. DESIGN: The phenomenological approach was used in this qualitative study. METHODS: In-depth, semi-structured interviews were conducted with 21 patients, from July to August of 2019. The data, which were collected, were analysed using the Colaizzi analysis procedure. RESULTS: According to the analysis results, the four benefit-finding experience themes of the cervical cancer patients were, respectively, determined to be as follows: Health cognition and behaviour changes; reshaping of personal strength; focussing on relationships with others; and facing life positively. CONCLUSIONS: The individual's cognition of health and their own strong qualities, and their external social support systems and information obtained and transmitted through interpersonal interactions, can promote the benefit finding. The findings suggest that medical staff should understand the traditional concepts of their patients, use their positive psychological potential, and build targeted nursing measures.

Clinical Study of Acupotomy for Knee Osteoarthritis Based on the Meridian-Sinew Theory: A Randomized Controlled Clinical Trial.

This study was performed to compare the effectiveness of acupotomy based on the meridian-sinew theory with acupotomy based on the anatomical theory in the treatment of knee osteoarthritis (KOA). A total of 124 patients with knee osteoarthritis were randomized into the meridian-sinew (MS) group (63 patients) and anatomy group (61 patients). In the MS group, acupotomy based on the meridian-sinew theory was performed. In the anatomy group, acupotomy based on anatomy was applied. Patients were subgrouped by TCM Constitutions. The Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index and visual analog scale (VAS) were used to evaluate treatment effectiveness. The results showed that VAS (F = 22.61, p < 0.01) and WOMAC (F = 24.84, p < 0.01) scores declined with time, and there was no significant difference between the two groups nor subgroups (Yang deficiency subgroup, Yin-Yang harmony subgroup, and the subgroup of the others). A total of 5 patients reported 6 cases of the minor adverse effect, and all patients achieved complete recovery without medical intervention. This study indicates that the effectiveness and safety of acupotomy based on the meridian-sinew theory are equivalent to that of acupotomy based on anatomy in KOA treatment.

[Application of "process management and evaluation" in resident standardization training plan in acupuncture-moxibustion department of hospital for postgraduates of non-acupuncture- moxibustion speciality].

The teaching effect of "process management and evaluation" was assessed in resident standardization training plan in acupuncture-moxibustion department of hospital for postgraduates of non-acupuncture-moxibustion speciality. A total of 120 postgraduates of non-acupuncture-moxibustion speciality participating in resident standardization training were randomized into an observation group (60 cases) and a control group (60 cases, 1 case dropped off). In the control group, the conventional training mode was used. In the observation group, the "process management and evaluation" was adopted, in which, the syllabus was refined, various teaching modes were cooperated and the summary was conducted once a week. The training results were evaluated at the end of 1-month shift test and questionnaire was issued in all of the postgraduates of the two groups. In the observation group, the score for theory and the score of each of the items for technical ability, named differentiation and treatment, technical manipulation and physician-patient communication, as well as the total score were all higher than the control group successively (P<0.05, P<0.01). The results of the student questionnaire showed that in the items as "being liable to the memory of relevant knowledge" "connection of theory with practical ability" "stimulating students' interest and subjective initiative" "self-learning ability" "clinical question handling ability" and "communication ability with patients" as well as the total score in the observation group were all higher than the control group successively (P<0.01, P<0.05). The teaching effect of "process management and evaluation" is obviously better than the conventional teaching mode.

[Acupuncture with regulating mind and spleen for diarrhea irritable bowel syndrome and sleep quality:a randomized controlled trial].

OBJECTIVE: To compare the effects between acupuncture with regulating mind and spleen and wes-tern medication for diarrhea irritable bowel syndrome (IBS-D). METHODS: Eighty-one patients were randomly at the ratio of 2 to 1 assigned into an acupuncture group (54 cases) and a western medication group (27 cases). Acupuncture with regulating mind and spleen was applied in the acupuncture group for 6 weeks at Baihui (GV 20), Yintang (GV 29), Tianshu (ST 25), Zusanli (ST 36), Shangjuxu (ST 37), Sanyinjiao (SP 6), and Taichong (LR 3), once every other day, 3 times a week. Pinaverium bromide tablet was used orally in the western medication group for 6 weeks, 50 mg a time, 3 times a day. IBS symptom severity score (IBS-SSS) were observed before and after 1-week, 6-week treatment. Pittsburgh sleep quality index (PSQI) was applied before and after 6-week treatment. Also, clinical efficacy was evaluated in the two groups. RESULTS: Three patients dropped out in the acupuncture group, and 1 in the western medication group. Except abdominal distension score after 1-week treatment in the western medication group, single scores and total scores of IBS-SSS apparently reduced in the two groups after 1-week and 6-week treatment (P<0.01, P<0.05). After 1-week treatment, the abdominal pain score of the acupuncture group was obviously lower than that of the western medication group (P<0.05). After 6-week treatment, with abdominal pain relief advantage, other results including the number of pain days, defecation satisfaction,life disturbance degree and total score of the acupuncture group were obviously lower than those of the wes-tern medication group (P<0.01,P<0.05). After 6-week treatment, the PSQI score and its change before and after treatment in the acupuncture group were superior to those in the western medication group (both P<0.05). The relief rate and relief plus obvious effective rate in the acupuncture group were higher than those in the western medication group[51.0% (26/51) vs 19.2% (5/26), P<0.01; 64.7% (33/51) vs 34.6% (9/26), P<0.05]. CONCLUSIONS: Acupuncture with regulating mind and spleen for diarrhea irritable bowel syndrome can more effectively relieve abdominal pain than pinaverium bromide tablet at the early stage. Its total effect and single effects are better at the later stage on abdominal pain, seizure frequency, defecation satisfaction, life disturbance, and sleep quality.
