Objective To summarize and explore the current state,hotspots,and trends in the field of surgical treatment for intracerebral hemorrhage(ICH)over the past decade through a bibliometric and visualization analysis of relevant literature.Methods Relevant Chinese and English literature on the surgical treatment of ICH,published from January 1,2014 to April 1,2024,was retrieved and screened from CNKI and Web of Science databases.Visualization analysis was conducted using CiteSpace,VOSviewer,and other software to analyze the number of published papers,authors,countries,institutions,etc.Social network analysis diagrams of authors,keyword clustering network analysis diagrams,keyword burst strength,and keyword timeline maps were also utilized.Results(1)A total of 3 456 relevant papers were included,with 2 173 in Chinese and 1 283 in English.From 2014 to 2021,the annual number of Chinese publications on ICH surgery was higher than that of English publications,but the number of Chinese publications began to decline from 2016.The number of English publications showed an overall increasing trend.(2)A total of 6 367 authors were identified from the English literature,with notable collaboration networks led by researchers such as Mocco J,Hanley DF,Ziai WC,You C,and Tang ZP.The Chinese literature included 6 522authors,with prominent collaboration networks led by Wang LK,Cai Q,Ku HB,Zhang S,and Zhu SQ.(3)Analysis of the countries involved in the English literature showed that 31 countries participated in research on ICH surgery,with China leading in the number of publications(505),followed by the United States(330)and Germany(106).The top three countries in centrality were the United States(0.32),China(0.16),and Canada(0.11).The top three institutions in English literature publications were Johns Hopkins University(51 papers),Ohio State University(39 papers),and Harvard University(38 papers).In China,Sichuan University(32 papers),Huazhong University of Science and Technology(30 papers),and Capital Medical University(27 papers)had multiple English publications;Wuhan University People's Hospital(15 papers),Affiliated Hospital of Guizhou Medical University(13 papers),and Affiliated Hospital of Yan'an University(13 papers)had multiple Chinese publications.There was close collaboration among research institutions in the English literature,whereas Chinese researchers often established research teams within their medical units with relatively less collaboration between teams.(4)Research on ICH surgery primarily focused on surgical methods,complications,and comprehensive perioperative treatment.Research hotspots included hypertensive ICH,minimally invasive surgical techniques,and perioperative management and treatment."neuroendoscopy"was the most recent emergent keyword in Chinese literature with high centrality and the strongest burst strength,while"randomized trial"had the highest burst strength in English literature.Research trends included the integration of artificial intelligence with minimally invasive techniques to optimize ICH surgery management and treatment strategies,analysis of risk factors,and evaluation of imaging value.Conclusions Over the past decade,the overall publication volume on the surgical treatment of ICH has been in a stable development phase,with research directions covering surgical techniques,diagnosis and treatment,evaluation,and management.Core research teams led by key authors were the main contributors to the publications.Future research hotspots and trends in ICH surgery may include the optimization of surgical techniques,complication management,large-scale multicenter clinical trials and integration of artificial intelligence with minimally invasive techniques.

Objective:To design and develop a digital auricle reconstruction simulation training system and to evaluate the application effect of the system.Methods:Based on 3D reconstruction and 3D printing technology, a new auricle reconstruction simulation training system was designed and developed from September 2019 to December 2021. Thirty-six basic volunteers (including 15 males and 21 females, aged from 22 to 27 years, with mean 23.1 years) without auricle reconstruction (surgical clinical standardized training students) were selected and divided into two groups (experimental group and control group) for clinical teaching experiment, and the teaching effect of simulation system was preliminarily evaluated.Results:Theoretical test scores before and after the intervention in the experimental group were 8.00 (4.75, 11.25) compared to 16.50 (13.00, 19.25) , P<0.001; design test scores were 2.00 (0, 4.25) compared to 7.00 (6.00, 10.00), P<0.001. In the control group, theoretical test scores before and after the intervention were 5.50 (3.75, 12.25) compared to 11.00 (9.50, 16.25), P<0.001; design test scores were 1.00 (1.00, 2.25) compared to 5.00 (3.75, 6.00), P<0.001. The improvement in the experimental group compared to the control group was significantly more pronounced with a statistically significant difference ( P<0.001). Conclusions:This system can assist teachers in teaching more systematically in auricle reconstruction training with autologous costal cartilage, and the teaching effect is better.

Tattooing involves the introduction of exogenous pigments and/or colorants into the dermis to produce a permanent design, which has become a common cosmetic method. However, the harmful substances in colorants and the non-standard operation of tattooing may lead to various acute and chronic complications after tattooing, which are always ignored. In this paper, the author introduced the types of tattooing colorants, the tattooing complications, and the treatments so as to provide clinical reference.

Objective To evaluate the clinical application of prophylactic uterine artery chemoembolization (UACE) together with sequential ultrasound-guided curettage of uterine cavity for the treatment of cesarean scar pregnancy (CSP). Methods The clinical data and follow-up results of 231 CSP patients who were treated with UACE together with sequential ultrasound-guided curettage of uterine cavity were retrospectively analyzed. Results After UACE together with sequential ultrasound-guided curettage of uterine cavity, successful termination of pregnancy was achieved in all 231 patients, neither hemorrhagic shock nor death occurred. The median amount of blood loss during curettage of uterine cavity was 10 ml. After curettage of uterine cavity, the median values of RBC, HGB and HCT were 3.53×1012/L, 105 g/L and 32％ respectively, the preoperative median values of which were 4.04×1012/L, 121 g/L and 36％ respectively, indicating there were a slight reduction in RBC, HGB and HCT after UACE, the differences were statistically significant (P＜0.001). The median values of β-HCG measured before UACE and after curettage of uterine cavity were29 069.0 U/ml and 1723.5 U/ml respectively, the difference was statistically significant (P＜0.001). According to the gestational age, the patients were divided into group A (gestational age ≤56 days) and group B (gestational age 57-81 days). Further stratified analysis showed that no statistically significant differences in blood loss during curettage of uterine cavity and in reduction degree of RBC, HGB and HCT after UACE existed between group A and group B. Conclusion Prophylactic UACE before CSP can effectively reduce the occurrence of massive bleeding during uterine curettage. For the treatment of CSP, UACE together with sequential ultrasound-guided curettage of uterine cavity is safe and reliable. Therefore, this therapy can be used as a routine treatment strategy for CSP.

The positive rate of Gram-negative bacilli was on the rise during year 2010-2014 (χ2 =84.74, P<0.01), and the top three Gram-negative bacilli were Pseudomonas aeruginosa, Acinetobacter baumannii and Haemophilus influenzae, which accounted for 72.5%(1 295/1 786) of the total Gram-negative strains, and the positive rates of first two bacilli were on the rise (χ2 =83.75 and 24.74, P<0.01).Gram-positive cocci were mainly Staphylococcus aureus and Hemolytic streptococcus, which accounted for 83.2% ( 897/1 078) of the total Gram-positive strains.Resistance rates of Pseudomonas aeruginosa to ceftazidime, cefoperazone, piperacillin/tazobactam were on the rise (χ2 =16.17, 13.48 and 11.44, P<0.05), while resistance rates to gentamicin and amikacin were on the decline (χ2 =16.54 and 16.63, P <0.05). Resistance rates of Acinetobacter baumannii to ceftazidime, cefoperazone/sulbactam and piperacillin/tazobactam were on the rise (χ2 =12.52, 10.85 and 14.14, P<0.05).Resistance rates of Haemophilus influenzae to ampicillin were on the rise (χ2 =10.21, P<0.05), and the positive rate of β-lactamase producing strains was also on the rise (χ2 =10.38, P<0.05).Resistance rates of Staphylococcus aureus to cefazolin and methicillin were on the rise (χ2 =15.44 and 12.53, P<0.05), but no vancomycin resistant strain was found .Hemolytic streptococcus were sensitive to all commonly used antibiotics .Conclusions Peritonsillar abscess in Wenzhou Central Hospital is mainly induced by Gram-negative bacilli infection . Pseudomonas aeruginosa, Acinetobacter baumannii and Staphylococcus aureus are the top three bacterial pathogens , and are highly resistant to most antibiotics .

OBJECTIVE: To investigate the correlation between tongue body MRI measurements and the lingual region obstruction in patients with obstructive sleep apnea hypopnea syndrome (obstructive sleep apnea hypopnea syndrome, OSAHS), and the relationship of two diagnosis methods in positioning obstructive level, in order to improve the preoperative diagnostic accuracy of obstructive level in OSAHS patients . METHOD: Fifty-nine patients with OSAHS definited by the AG200 sleep apnea monitoring and obstruction plane positioning system was included. They all underwent tongue MRI scan, after three-dimensional reconstruction, the tongue body length to diameter, relative thickness, basal diameter, wide around central about wide diameter and tongue body volume were measured. The lower blocking (mainly composed of lingual region) constituent ratio P established by AG200 was correlated with tongue parameters measured by MRI. At the same time, To analysis of differences of P in patients with different degree of OSAHS. RESULT: Among these patients with OSAHS in different degree, the coefficient correlation between tongue parameters(tongue length, relative thickness, basal diameter, wide middle diameter, tongue body volume) and lower blocking constitute ratio P werer LP = 0.051,rHP = 0.069, r1 = 0.215, r2 = 0.147, rVP = 0.259, respectively. lower obstruction of form than the differences had statistical significance. The measured tongue parameters and value P(the lower blocking constituent ratio) were negatively correlated, which demonstrated that exclusing of the larynx and hypopharynx airway obstruction, the lower airway obstruction detected by AG200 was related with tongue parameters measured by MRI, and was strongestly related with the tongue body volume. CONCLUSION The volume of tongue and AG had correlation in judgement of lower blocking. In OSAHS patients the lower blocking constituent ratio varies between the defferent severity groups of the disease, the combina tion of the two method can be used to predict the obstructive plane in OSAHS patients with upper airway obstruction, and provide the basis for the individual treatment of patients with OSAHS.

OBJECTIVETo investigate the impact of metal implants with different materials on radiation dose distribution based on film measurement method.

METHODSTitanium plate, titanium intramedullary pin and stainless steel plate were set into phantom and irradiated separately by 6 MV and 15 MV X ray from linear accelerator. Dose distributions derived from different materials metal implants were measured and analyzed by film dosimeter.

RESULTSFor 6 MV X ray, the maximum interface dose increments of titanium plate, titanium intramedullary pin and stainless steel plate were 12.3%, 15.4% and 20.3%. As the radiation energy was increased from 6 MV to 15MV, the maximum interface dose increment of the titanium plate rose from 12.3% to 15.1%, the maximum interface dose increment of the steel plate rose from 20.3% to 30.8%.

CONCLUSIONSMetal implants with different materials have obvious impact on radiation dose distribution. With the increase of the metal atomic number and energy of radiation, the degree of elevated dose also increases. These results suggest that correction of dose distribution is required for radiotherapy of patients with metal implants.
