Objective To explore the pathogenesis and prognostic factors of liposarcoma in the head and neck region, and simultaneously analyze the efficacy of different treatment regimens. Methods A retrospective analysis was performed on all patients with primary untreated head and neck liposarcoma who were diagnosed and underwent surgical treatment at our hospital from January 2008 to January 2024. All patients were monitored during follow-up, and their prognoses were analyzed using SPSS software. Results A total of 30 patients were included in the study. Liposarcoma accounted for up to 60% of the cases in the orbit, while the remaining liposarcomas were primarily located in various interspaces of the neck. Dedifferentiated liposarcoma was the most common type, comprising 33%, while myxoid pleomorphic liposarcoma was the rarest at 4%. The tumor pathological type (P<0.001) and Ki67 (P=0.014) significantly affected the tumor control rate. However, an analysis of disease-specific survival rates revealed no significant differences across various factors (all P>0.05). Conclusion The prognosis of head and neck liposarcoma is better compared to that of liposarcomas in other parts of the body. However, myxoid pleomorphic liposarcoma, pleomorphic fat sarcoma, and high Ki67 levels are indicators of poor prognosis. Additionally, postoperative adjuvant radiotherapy does not significantly enhance disease-specific survival rates.

Objective To investigate the expression of N-acetyltransferase 10(NAT10),serine hydroxymethyltransferase 2(SHMT2)and YTH domain family protein 1(YTHDF1)in lung cancer tissues and their correlation with clinicopathological characteristics and prognosis.Methods A total of 98 lung cancer patients admitted to our hospital from April 2020 to April 2021 were regarded as the observation subjects.The cancerous tissues and adjacent tissues of the patient during surgery were collected.Immunohistochemistry was used to detect the expression levels of NAT10,SHMT2 and YTHDF1.The patients were followed up for 3 years and divided into the survival group and the death group according to their prognosis.The data of general clinicopathological characteristics were collected and analyzed.The relationship between NAT10,SHMT2 and YTHDF1 with the prognosis of patients were analyzed.Multivariate Cox regression was used to analyze the influencing factors of lung cancer patients.Results The high expression ratios of NAT10,SHMT2 and YTHDF1 in cancer tissues were obviously higher than those in adjacent tissues(P＜0.05).The expression of NAT10 and YTHDF1 was related to clinical stage,degree of differentiation and lymph node metastasis(P＜0.05),and the expression of SHMT2 was correlated with clinical stage,degree of differentiation,tumor diameter,and lymph node metastasis(P＜0.05).There were statistically significant differences in tumor diameter,clinical stage,degree of differentiation,lymph node metastasis,and expressions of NAT10,SHMT2,and YTHDF1 between the survival group and the death group(P＜0.05).NAT10,SHMT2,YTHDF1 patient survival rates significantly below the low of high expression patients(x2=6.354,P=0.012,x2=8.512,P=0.004,x2=4.791,P=0.029).Lymph node metastasis,high expression of NAT10,SHMT2 and YTHDF1 are all risk factors affecting the prognosis of patients(P＜0.05).Conclusion NAT10,SHMT2,and YTHDF1 are all highly expressed in the tissues of lung cancer,and have a certain correlation with clinical pathological characteristics and prognosis.They may serve as relevant evaluation indicators for the prognosis of lung cancer patients.

Objective To explore the feasibility and safety of ultrasound-guided percutaneous microwave ablation for unresectable pancreatic cancer.Methods Totally 84 patients who underwent ultrasound-guided percutaneous microwave ablation for unresectable pancreatic cancer were enrolled,and the technical success rate,complete ablation rate,complication rate,pain relief rate and survival time,etc.were observed.Results The median age of 84 cases was 61.5 years.Totally 86 tumors,including 44.19％(38/86)at the head/neck and 55.81％(48/86)at the body/tail of pancreas were detected,and a total of 85 ablation sessions were performed with the median ablation energy applied per tumor of 9.90(1.08,21.60)kJ and the complete ablation rate of 42.86％(36/84).The technical success rate was 100％(85/85).Thirty-nine complication events occurred in 25 cases,no ablation-related death.Among 34 patients underwent ablation mainly for pain symptoms,the pain score decreased from(6.22±1.12)points before treatment to(1.94±1.64)points after treatment(P＜0.001).During 6.8(3.3,12.9)months' follow-up,the mean survival time was(8.5±6.7)months,and all 47 patients died due to tumor progression.Conclusion Ultrasound-guided percutaneous microwave ablation was safe and feasible for unresectable pancreatic cancer.

Objective To analyze the mortality trend of malignant tumors and the early death and life reduction levels of residents in Lanzhou from 2014 to 2022,so as to provide a basis for the prevention and control of malignant tumors.Methods The mortality data of malignant tumors of residents in Lanzhou from 2014 to 2022 were collected,and the crude mortality rate,standardized mortality rate,early death probability,potential life loss years(PYLL),life reduction rate(PYLLR)and annual percentage of change(APC)were used to analyze the mortality trend of malignant tumors and early death and life reduction.Results From 2014 to 2022,the cumulative number of deaths from malignant tumors in Lanzhou residents was 21192,with an average crude mortality rate of 62.74/100000 and an annual standardized mortality rate of 55.30/100000.The mortality rate of malignant tumors in the three age groups of 0~14 years,15~64 years old and≥65 years old showed that the mortality rate was higher with the older age,and the mortality rate increased sharply in the≥65－year－old population,and the mortality rate of each age group showed a decreasing trend year by year,and it was statistically significant(P<0.05).The top 7 were lung cancer,gastric cancer,liver cancer,colorectal cancer,pancreatic cancer,esophageal cancer and breast cancer,except for breast cancer,the crude mortality rate of other diseases was higher in men than in women,and the difference in crude mortality between men and women was statistically significant(all P<0.01).From 2014 to 2022,the probability of early death of malignant tumors among residents aged 30~69 in Lanzhou was 2.94%,and its APC was －8.04%(P<0.05).From 2014 to 2022,the probability of premature death caused by lung cancer,gastric cancer,colorectal cancer,esophageal cancer and breast cancer among residents aged 30~69 in Lanzhou showed a downward trend,and the APCs were － 6.22%,－15.94%,－4.56%,－16.99%and －12.54%(P<0.05).The analysis of early death and life loss showed that the PYLL caused by malignant tumors accumulated 234141 person－years,of which 128727 person－years were male and 105413 person－years were female.The APC of PYLL was －5.92%(P<0.05).PYLLR was 6.97‰,7.47‰ for men and 6.45‰ for women.The APC of PYLLR was －6.71%(P<0.05).The trends of PYLL and PYLLR in men and women were statistically significant(P<0.05).Conclusion From 2014 to 2022,the probability of early death and disease burden of malignant tumors in Lanzhou showed a downward trend year by year.Lung cancer,gastric cancer,liver cancer and colorectal cancer are the main malignant tumors in Lanzhou City,which should be prevented and treated with priority,and the screening and detection of malignant tumors in the elderly population should be strengthened to reduce the burden of malignant tumors.

Objective To observe the effect of tuina on glutamate content and synaptic ultrastructure in spinal dorsal horn of rats with chronic sciatic nerve compression injury;To explore the potential mechanism of tuina regulation of the SNAP25/VGLUT2 pathway in alleviating lumbar disc herniation.Methods A chronic sciatic nerve compression injury model was used to simulate neuropathic pain in lumbar disc herniation.24 SD rats were randomly divided into blank group,model group and tuina group,with 8 rats in each group.From the 4th day after modeling,the tuina group was intervened with the tuina method for 10 minutes once a day for 14 consecutive days.The paw withdrawal threshold(PWT)and paw withdrawal latency(PWL)of rats in each group on the day before modeling,and the 4th,10th,14th and 17th days after modeling were detected.The spinal cord tissue of the modeling side was taken,synaptic ultrastructure of spinal dorsal horn neurons was observed using transmission electron microscopy,immunofluorescence staining was used to detect the expression of NR2A in the spinal dorsal horn,Western blot was used to detect the expression of SNAP25 protein in the spinal dorsal horn,immunohistochemistry was used to detect the expression of VGLUT2 in the spinal dorsal horn,ELISA was used to detect the content of glutamate in the spinal dorsal horn.Results Compared with the blank group,PWT and PWL of the model group were significantly reduced on the 4th,10th,14th and 17th days after modeling(P<0.001),with accumulation of vesicles in the presynaptic membrane of the dorsal horn of the spinal cord,increase in the area of the postsynaptic dense zone,and enlargement of the synaptic cleft,while the protein expressions of NR2A,SNAP25 and VGLUT2 in the spinal dorsal horn increased(P<0.05,P<0.001),and the content of glutamate increased(P<0.001).Compared with the model group,PWT and PWL of the tuina group rats significantly increased on the 10th,14th and 17th days after modeling(P<0.001),synaptic vesicles were evenly distributed,the area of the postsynaptic dense zone decreased,and the synaptic cleft decreased,while the protein expressions of NR2A,SNAP25 and VGLUT2 in the spinal dorsal horn decreased(P<0.05,P<0.001),and the content of glutamate decreased(P<0.01).Conclusion Tuina may regulate the content of glutamate through the SNAP25/VGLUT2 pathway in the spinal dorsal horn,improve the synaptic ultrastructure of neurons,and have an analgesic effect on lumbar disc herniation.

Objective To investigate the current status of home medicine cabinet management and unmet needs for home-based pharmaceutical services among elderly hypertensive patients in Hubei Province,and to provide evidence for optimizing home pharmaceutical care models.Methods From July 2022 to March 2023,310 elderly hypertension patients across Hubei Province were enrolled.Pharmacists conducted home visits to administer structured questionnaires capturing demographics and blood pressure control rates,perform medication categorization and quality assessments of home medicine cabinets and document cabinet management issues in real-time.Results Among 290 valid questionnaires,binary logistic regression revealed better blood pressure control in non-working and non-smoking individuals.Medicine cabinet audits identified three critical issues:failure to separate Chinese and chemical medicines,duplicate medications with similar ingredients and missing original packaging.Post-intervention,all cabinets demonstrated proper medication categorization and storage compliance.Conclusions Significant medication safety hazards exist in elderly hypertensive patients'home medicine cabinets.Pharmacist-led home interventions effectively cleared substandard medications and improved medication safety.Future home pharmaceutical services should focus on optimizing cabinet management protocols,enhancing medication safety awareness and personalizing pharmaceutical care to ensure precise and effective home-based medication management.

OBJECTIVE To investigate the prognostic factors of chondrosarcoma of the larynx,deeply analyze its clinical data,and provide a theoretical basis for better treatment of chondrosarcoma of the larynx.METHODS A retrospective analysis was conducted on the complete clinical data of patients with primary chondrosarcoma of the larynx admitted to the Department of Otolaryngology Head and Neck Surgery,Beijing Tongren Hospital,Capital Medical University from January 2010 to December 2024.RESULTS A total of 15 patients were included,including 11 males and 4 females,with a gender ratio of 11∶4.The average age of onset was 57.3 years,and the average clinical symptom duration was 12.2 months.The tumors were mainly located in the cricoid cartilage in 11 patients,in the arytenoid cartilage in 2 patients,and in the thyroid cartilage in 2 patients.Tumor grading showed that 7 patients were grade I and 8 were grade II.Four patients underwent transoral laser minimally invasive surgery,2 patients underwent partial laryngectomy+tracheotomy,and 9 patients underwent total laryngectomy/cervical lymph node dissection+tracheostomy.The 5-year overall survival rate was 85.7%,the 5-year disease-specific survival rate was 100%,and the 5-year local-regional control rate was 90.9%.Gender,tumor location,tumor grade,Ki-67,tumor size,and whether larynx preservation surgery was performed did not affect the local-regional control rate or disease-specific survival rate.CONCLUSION Laryngeal chondrosarcoma generally has a longer disease history and is difficult to detect.The pathological type is mostly well-differentiated.Regional or distant metastasis is rare,and the long-term survival rate is good.Surgical resection is the preferred treatment option.On the basis of not reducing the tumor control rate,surgery that prioritizes preserving laryngeal function should be given priority,while comprehensive treatment is generally not recommended.

OBJECTIVE To investigate the selection strategy for recipient vessels in free flap reconstruction of head and neck defects.METHODS A retrospective analysis was conducted on 96 patients who underwent 99 free flap reconstructions for head and neck defects between January 2020 and December 2024.Recipient vessel selection,flap survival,and postoperative complications were analyzed based on defect location and flap type.RESULTS In 99 cases microvessel anastomosis,the recipient arteries were superior thyroid artery in 49 branches,facial artery in 28 branches,superficial temporal artery in 14 branches,lingual artery in 5 branches.external carotid artery in 1 branch,transverse cervical artery in 1 branch,and superior laryngeal artery in 1 branch.Venous anastomosis was performed in 104 branches,with 94 cases in 1 venous anastomosis and 5 cases in 2 venous anastomoses.The recipient veins selected were facial vein in 62 branches,external jugular vein in 21 branches,superficial temporal vein in 12 branches,retromandibular vein in 3 branches,middle thyroid vein in 2 branches,internal jugular vein in 2 branches,middle temporal vein in 1 branch,and superior thyroid vein in 1 branch.Complete flap necrosis occurred in 5 cases,and partial necrosis occurred in 4 cases.When the recipient vessels were deficient,the lingual artery was chosen in 3 cases,the facial artery in 1 case,the external jugular vein in 3 cases,the internal jugular vein with end-to-side anastomosis in 1 case,and the common facial vein with end-to-side anastomosis in 1 case.CONCLUSION In free flap reconstruction for head and neck defects,the superior thyroid artery,facial artery,and superficial temporal artery are commonly used as recipient arteries,while the facial vein,external jugular vein,and superficial temporal vein are frequently selected as recipient veins.When recipient vessels are scarce,the ipsilateral lingual artery,transverse cervical artery,and main trunk of the internal jugular vein can serve as alternative recipient vessels.
