Objective To explore the evaluation on the curative effect of digital subtraction angiography(DSA)-guided radiofrequency ablation in patients with lumbar disc herniation(LDH)based on infrared thermal imaging technology.Methods A total of 90 patients with LDH treated in the hospital were enrolled as the research objects between February 2019 and February 2022.According to different treatment methods,they were divided into observation group(n=45)and control group(n=45).The control group was treated with radiofrequency ablation,while observation group was treated with DSA-guided radiofrequency ablation.The scores of visual analogue scale(VAS),Oswestry disability index(ODI)and Japanese Orthopaedic Association(JOA),and levels of serologic indexes[interleukin-1β(IL-1β),interleukin-6(IL-6),tumor necrosis factor-α(TNF-α)]were compared between the two groups before treatment and at 1 month and 3 months after treatment.The skin temperature of lesions was detected by infrared thermal imaging,and its correlation with VAS,ODI and JOA scores was analyzed by Pearson correlation analysis.Results Before treatment,there was no significant difference in VAS score between the two groups(P＞0.05).At 1 month and 3 months after treatment,VAS scores in both groups were decreased,which were lower in observation group than control group(P＜0.05).Before treatment,there was no significant difference in ODI and JO A scores between the two groups(P＞0.05).At 1 month and 3 months after treatment,ODI scores in both groups were decreased,which were lower in observation group than control group,while JOA scores were increased,which were higher in observation group than control group(P＜0.05).Before treatment,there was no significant difference in levels of serum IL-1β,IL-6 and TNF-α between the two groups(P＞0.05).At 1 month and 3 months after treatment,levels of serum IL-1 β,IL-6 and TNF-α in both groups were decreased,which were lower in observation group than control group(P＜0.05).Before treatment,there was no significant difference in skin temperature of lesions between the two groups(P＞0.05).At 1 month and 3 months after treatment,skin temperature of lesions in both groups was decreased,which was lower in observation group than control group(P＜0.05).Pearson correlation analysis showed that skin temperature of lesions was positively correlated with VAS,ODI and JOA scores at 1 month and 3 months after treatment(r=0.455,0.502,0.523,0.675,0.659,0.611,P＜0.05).Conclusion Curative effect of DSA-guided radiofrequency ablation is good on LDH patients,and infrared thermal imaging can effectively evaluate the curative effect.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To assess the impact of preoperative Naples prognostic score on the prognosis of patients with hepatocellular carcinoma (HCC) after hepatic resection.Methods:Retrospective analysis was conducted on the data of 323 patients with HCC who underwent radical hepatectomy in Zhejiang Provincial People's Hospital from January 2012 to December 2017, including 281 males and 42 females, aged (56.6±11.3) years. All patients were divided into three groups according to their preoperative Naples prognostic scores: group A (0) ( n=37), group B (1-2) ( n=193), group C (3-4) ( n=93). Survival was analysed by the Kaplan-Meier method, and differences in survival were compared by the log-rank test. Univariate and multivariate Cox regression were used to analyse the effect of Naples prognostic score on prognosis. Results:The 1-, 3- and 5-year cumulative survival rates of HCC patients after hepatectomy were 91.9%, 78.4% and 68.3% in the A group, 89.1%, 76.1% and 64.4% in the B group, and 84.9%, 63.3% and 43.5% in the C group, respectively, and the cumulative survival rates showed a decreasing trend among the three groups, and the differences were statistically significant (all P<0.05). The recurrence-free survival rates at 1, 3 and 5 years after hepatectomy were 93.4%, 63.3% and 44.3% in the A group, 77.7%, 46.5% and 35.6% in the B group, and 64.1%, 41.1% and 28.2% in the C group, respectively, and the recurrence-free survival rates showed a decreasing trend among the three groups, and the differences were statistically significant (all P<0.05). On Cox multivariate analysis, patients with HCC of 3-4 had a higher risk of death after hepatic resection than those patients of 0 ( HR=2.011, 95% CI: 1.048-3.859, P=0.036), and the risk of postoperative recurrence was also higher than those patients of 0 ( HR=1.820, 95% CI: 1.081-3.066, P=0.024). Conclusion:Preoperative Naples prognostic score performs as a prognostic influence factor on survival and recurrence-free survival after hepatectomy in patients with HCC.

Objective:To investigate the analgesic effect of intravenous anesthesia induction combined with anterior quadratus lumborum block (AQLB)and related hemodynamic changes in patients undergoing laparoscopic retroperitoneal partial nephrectomy (RPN).Methods:A total of 116 patients undergoing elective laparoscopic partial nephrectomy for renal tumors in Jinhua Central Hospital from August 2021 to February 2022 were randomly divided into two groups with 58 cases in each group. Patients in control group received intravenous anesthesia , while those in study group received intravenous anesthesia induction with AQLB. The analgesic effect was evaluated at 1, 6, 12, 24, and 48 h after the operation. The hemodynamics were monitored at the time of entering the operating room (T 0), 3 min after induction of anesthesia (T 1), at the beginning of the operation (T 2), after the operation (T 3), and leaving the operating room (T 4). Microcirculation was assessed at 1, 6, 12, 24, and 48 h after operation. Cognitive function was assessed 30min before anesthesia, 6 h, 24 h, and 72 h after operation. Results:At 1, 6, 12, 24 and 48 h after operation, the visual analogue scale (VAS) of the resting (quiet state) pain in the study group were 3.2±1.2, 2.6±0.3,2.0±0.4, 1.5±0.4 and 0.8±0.2, which were significantly lower than those in control group (4.0±1.7, 3.4±0.7, 2.9±0.5, 1.7±0.5 and 1.2±0.3) ( t=2.93, P=0.004; t=8.00, P<0.001; t=10.07, P<0.001; t=2.38, P=0.019; t=8.45, P<0.001). There was no significant difference in heart rate and mean arterial pressure (MAP) at T 0 between two groups ; no significant difference in the heart rate at T 1, T 2, T 3 and T 4. There were significant differences in MAP levels at T 1, T 2, T 3 and T 4 between study group [(80.0±8.0)mmHg (1 mmHg=0.133 kPa), (84.4±8.4)mmHg, (80.4±5.7)mmHg, (86.4±4.7)mmHg and control group (77.1±7.5)mmHg, (88.0±8.6)mmHg, (83.0±7.7)mmHg, (92.2±6.2) mmHg; t=2.01, P=0.046; t=2.28, P=0.024; t=2.07, P=0.041; t=5.68, P<0.001]. At 6, 12, 24 and 48 h after operation, the morphological scores of tube loops in the study group were 1.0±0.2, 0.8±0.2, 0.7±0.1 and 0.7±0.1, which were lower than those in the control group (1.1 ±0.2, 0.9±0.2, 0.8±0.2 and 0.8±0.1; t=2.69, P=0.008; t=2.69, P=0.008; t=3.41, P=0.001; t=5.39 , P < 0.001). The blood flow status scores of the study group were 1.1±0.2, 0.9±0.2, 0.8±0.2 and 0.6±0.1, which were lower than those of the control group (1.2±0.2, 1.0±0.2, 0.9±0.2 and 0.7±0.1; t=2.69, P=0.008; t=2.69, P=0.008; t=2.69, P=0.008; t=5.39, P<0.001). The cognitive function scores of the study group and the control group were 24.4±1.0, 27.1±0.9 and 23.5±0.9, 26.7±0.9 at 6 h and 24 h after operation ( t=5.10, P<0.001; t=2.39, P=0.018); while there were no significant at 72 h after operation between two groups (28.2±0.9 vs. 28.1±0.8, t=0.63, P=0.529). Conclusion:Intravenous anesthesia induction combined with anterior quadratus lumborum block has a good analgesic effect in patients undergoing RPN, with stable hemodynamics and microcirculation, and not affecting cognitive function of patients.

Objective:To explore the medical costs and influencing factors of patients diagnosed with Brucellosis in Xinjiang Uygur Autonomous Region (Xinjiang).Methods:Information on demographics, medical visits, and costs of patients diagnosed with Brucellosis were collected between January 1,2017 and December 31,2019. The effects of different genders, age groups, clinical stages, and comorbidities on patients' health care utilization and medical costs were analyzed by nonparametric tests. The median was used to describe the outpatient and inpatient costs of patients with Brucellosis.Results:A total of 13 532 patients (8 113 outpatient and 5 419 inpatient cases) were included in the analysis. A total of 67.8% (9 176/13 532) were male, with an average age of (42.7±15.4 ) years; age between 18-44 years (46.6%, 6 304/13 532) and 45-59 years (34.2%,4 622/13 532) were the dominant groups. The mean age of inpatients [(43.3±15.7) years] was higher than that of outpatients [(42.3±15.1) years, Z=-3.85, P<0.001]. When hospitalized patients are treated,systemic symptoms were common with fever (36.9%, 1 997/5 419) and fatigue (36.6%, 1 983/5 419), and with joint/muscle pain (68.9%, 3 735/5 419) being the highest proportion of local symptoms. A total of 79.1% (4 289/5 419) of inpatients were diagnosed with acute Brucellosis. A total of 46.5% (2 519/5 419) of inpatients had complications;skeletal system complications ranked the highest. The average number of outpatient visits per outpatient was (1.6±1.4) times. The duration of hospitalization was (11.3±4.2) days, with longer days for patients in the chronic phase and with complications ( P<0.05). A total of 89.3% (4 840/5 419) of inpatients had outpatient records in the same year,and the average number of outpatient visits per patient was (3.6±2.6) times. Outpatient medical costs were dominated by laboratory and drug costs (75.1%), and inpatient costs were dominated by drug, laboratory, and other costs (74.4%). Outpatient medical expenses M( Q1, Q3) were 61(52, 497) Yuan, 61 (51, 346) Yuan and 58 (46, 318) Yuan,respectively. Inpatients' medical expenses M ( Q1, Q3) were 8 214 (6 355, 10 721) Yuan,9 095 (7 018, 12 155) Yuan and 9 492 (7 530, 12 351) Yuan, respectively. For patients, age, clinical stages,complications,and joint/muscle pain symptoms were influential factors for hospitalization costs ( P<0.001). Conclusions:The economic burden was higher for inpatients, especially those in the high age group, with chronic phases and skeletal and neurological complications. Improving patients' awareness of early treatment, standardized treatment, and reducing chronicity and complications are the main points in reducing the economic burden caused by Brucellosis diagnosis and treatment.

Objective:To explore the medical costs and influencing factors of patients diagnosed with Brucellosis in Datong of Shanxi province.Methods:Information on demographics, medical visits, and costs of patients diagnosed with Brucellosis between January 1, 2017, and December 31, 2019, were collected. Health care utilization and medical costs were analyzed from different genders, age groups, underlying diseases, clinical stages, and comorbidities.Results:A total of 2 289 patients (1 715 outpatient and 574 inpatient cases) were included in the analysis. 72.0% (1 649/2 289) were male, with an average age of (49.6±15.5) years; age between 45-59 years was the dominant group (36.2%,829/2 289). The mean age of inpatients (51.4±16.0) was higher than that of outpatients (49.0±15.2)( Z=-4.01, P<0.001). The average number of outpatient visits per outpatient was (1.6±1.5) times. The duration of hospitalization was (14.6±9.9) and (20.8±11.4) days for patients with central nervous system complications and (16.6±9.5) days for vascular system complications. Of the inpatients, 51.0% (293/574) had underlying diseases, and 30.3% (174/574) had endocrine and metabolic diseases. 54.0% (310/574) of inpatients were diagnosed with acute Brucellosis, and 46.0% (264/574) were diagnosed with chronic Brucellosis. A total of 64.3% (369/574) of inpatients had complications, 30.3% (174/574) of digestive system complications, followed by skeletal system complications (29.1%, 167/574). Among outpatients, age significantly affected medical costs ( P<0.001). For inpatients, age and complications and treatment effect were influential factors ( P<0.05). Patients with the combined skeletal system and central nervous system complications had significantly higher medical costs ( P<0.001). Conclusions:The medical costs for outpatient cases of Brucellosis were moderate. However, the economic burden was higher for inpatients, especially those with skeletal and neurological complications. Early detection, diagnosis, and treatment of cases were essential to avoid chronic Brucellosis and its complications and reduce medical costs.

Objective:To explore the correlation between enhanced CT quantitative parameters and malignant biological behavior and prognosis of colon cancer.Methods:From February 2017 to October 2019, 100 patients with colon cancer in Anhui Wanbei Coal-Electrivity Group Gernal Hospital were selected as the research subjects, and all performed enhanced CT examination. The serum tumor markers carcinoembryonic antigen (CEA), carbohydrate antigen 19-9 (CA19-9) levels were detected. According the mean value of CEA, CA19-9, the patients were divided into different group, and CEA< 28.36 pmol/L was considered to below level, ≥ 28.36 pmol/L was high; CA19-9<40.26 pmol/L was considered to below level, ≥ 40.26 pmol/L was high. The quantitative parameters of enhanced CT in patients with colon cancer with different serum CEA and CA19-9 levels and different pathological indicators (CT scan value, enhanced value, degree of enhancement) were compared. The correlation between serum tumor marker levels, malignant biological behavior of colon cancer and quantitative parameters of enhanced CT were explored. After 12-months′ followed-up, the clinical data of patients with different prognosis and enhanced CT parameters were counted. The factors affecting the prognosis of colon cancer patients and the predictive value of enhanced CT quantitative parameters on the prognosis of patients were explored.Results:The CT scan value, enhancement value and enhancement degree of colon cancer patients with low levels of serum CEA and CA19-9 were lower than those with high levels: (30.16 ± 5.14) HU vs. (38.51 ± 5.72) HU, (55.74 ± 8.12)HU vs. (78.62 ± 8.97) HU, (25.58 ± 3.60) HU vs. (40.11 ± 3.14) HU, the differences were statistically significant ( P<0.05). There was a positive correlation between serum CEA and CA19-9 levels in patients with colon cancer and CT scan value, enhancement value, and degree of enhancement ( P<0.05). The CT enhancement value and enhancement degree of colon cancer patients were related to Dukes staging, differentiation degree, lymph node metastasis and lymphatic infiltration in colon cancer patients. The CT scan value was related to Dukes staging, lymph node metastasis and lymphatic infiltration of colon cancer patients ( P<0.05). The risk factors for death of colon cancer patients included age, Dukes staging, degree of differentiation, lymph node metastasis, lymphatic invasion, CT scan value, enhancement value, and degree of enhancement ( P<0.05). The area under the curve (AUC) of CT scan value, enhancement value, and enhancement degree combined to predict the prognosis of colon cancer patients was 0.873, which was greater than the single prediction of each parameter. The best sensitivity and specificity of combined prediction were 76.92% and 88.37%, respectively. Conclusions:There is a certain correlation between the enhanced CT quantitative parameters and the malignant biological behavior of patients with colon cancer. The increased detection value is risk factor for the prognosis.
