ObjectiveTo compare the clinical features of patients with hepatitis B virus （HBV）-related early-onset liver cancer and those with late-onset liver cancer， to assess the severity of the disease， and to provide a theoretical basis for the early diagnosis and treatment of liver cancer. MethodsA retrospective analysis was performed for 695 patients who were diagnosed with HBV-related liver cancer for the first time in Guangzhou Eighth People’s Hospital， Guangzhou Medical University， from January 2019 to August 2023， among whom 93 had early-onset liver cancer （defined as an age of50 years for female patients and40 years for male patients） and 602 had late-onset liver cancer （defined as an age of ≥50 years for female patients and ≥40 years for male patients）. Related clinical data were collected， including demographic data， clinical symptoms at initial diagnosis， comorbidities， smoking history， drinking history， family history， routine blood test results， biochemical parameters of liver function， serum alpha-fetoprotein（AFP）， virological indicators， coagulation function， and imaging findings. The pan-inflammatory indices neutrophil-to-lymphocyte ratio （NLR）， platelet-to-lymphocyte ratio （PLR）， and lymphocyte-to-monocyte ratio （LMR） were calculated， as well as FIB-4 index， aspartate aminotransferase-to-platelet ratio index （APRI）， S index， Model for End-Stage Liver Disease （MELD） score， Child-Turcotte-Pugh （CTP） score， albumin-bilirubin （AIBL） grade， and Barcelona Clinic Liver Cancer （BCLC） stage. The independent-samples t test was used for comparison of normally distributed continuous data between two groups， and the Wilcoxon rank-sum test was used for comparison of non-normally distributed continuous data between two groups； the chi-square test or Fisher’s exact test were used for comparison of categorical data between two groups. ResultsThere were significant differences between the two groups in the proportion of male patients and the incidence rates of diabetes， hypertension， and fatty liver disease （χ²=6.357， 15.230， 11.467， and 14.204， all P0.05）， and compared with the late-onset liver cancer group， the early-onset liver cancer group had a significantly higher proportion of patients progressing to liver cancer without underlying cirrhosis （χ²=24.657， P0.001） and a significantly higher proportion of patients with advanced BCLC stage （χ²=6.172， P=0.046）. For the overall population， the most common clinical symptoms included abdominal distension， abdominal pain， poor appetite， weakness， a reduction in body weight， edema of both lower limbs， jaundice， yellow urine， and nausea， and 55 patients （7.9%） had no obvious symptoms at the time of diagnosis and were found to have liver cancer by routine reexamination， physical examination suggesting an increase in AFP， or radiological examination indicating hepatic space-occupying lesion； compared with the late-onset liver cancer group， the patients in the early-onset liver cancer group were more likely to have the symptoms of abdominal distension， abdominal pain， and jaundice （all P0.05）. Compared with the late-onset liver cancer group， the early-onset liver cancer group had a significantly larger tumor diameter （Z=2.845， P=0.034）， with higher prevalence rates of multiple tumors and intrahepatic， perihepatic， or distant metastasis （χ²=5.889 and 4.079， both P0.05）， and there were significant differences between the two groups in tumor location and size （χ²=3.948 and 11.317， both P0.05）. Compared with the late-onset liver cancer group， the early-onset liver cancer group had significantly lower FIB-4 index， proportion of patients with HBsAg ≤1 500 IU/mL， and levels of LMR and Cr （all P0.05）， as well as significantly higher positive rate of HBeAg and levels of log₁₀ HBV DNA， AFP， WBC， Hb， PLT， NLR， PLR， TBil， ALT， Alb， and TC （all P0.05）. ConclusionCompared with late-onset liver cancer， patients with early-onset liver cancer tend to develop liver cancer without liver cirrhosis and have multiple tumors， obvious clinical symptoms， and advanced BCLC stage， which indicates a poor prognosis.

Thrombocytopenia is one of the common complications of cirrhotic patients, which can induce an increasing bleeding risk and closely correlate with bleeding following invasive procedures. Consequently, how to respond to thrombocytopenia is crucial for improving the prognosis of patients with cirrhosis. This article reviews the main mechanisms of cirrhosis concurrent with thrombocytopenia, as well as the corresponding clinical management strategies.

Objective    To assess mid- and long-term outcomes and share our clinical method of reduction ascending aortoplasty (RAA) in adult patients undergoing aortic valve replacement (AVR). Methods    We retrospectively analyzed clinical data of 41 adult patients with aortic valve disease and ascending aortic dilatation before and after operation of RAA+AVR in Fuwai Hospital from January 2010 to July 2017. There were 28 male and 13 female patients aged 28-76 (53.34±12.06) years. Twenty-three patients received AVR+RAA using the sandwich technique (a sandwich technique group), while other 18 patients received AVR+ascending aorta wrap (a wrapping technique group). Ascending aorta diameter (AAD) was measured by echocardiography or CT scan preoperatively and postoperatively. Results    There was no perioperative death. The mean preoperative AAD in the sandwich technique group and the wrapping technique group (47.04±3.44 mm vs. 46.67±2.83 mm, P=0.709) was not statistically different. The mean postoperative AAD (35.87±3.81 mm vs. 35.50±5.67 mm, P=0.804), and the mean AAD at the end of follow-up (41.26±6.54 mm vs. 38.28±4.79 mm, P=0.113) were also not statistically different between the two groups. There were statistical differences in AAD before, after operation and at follow-up in each group. All 41 patients were followed up for 23-108 (57.07±28.60) months, with a median follow-up of 51.00 months. Compared with that before discharge, the AAD growth rate at the last follow-up was –1.50-6.78 mm/year, with a median growth rate of 0.70 mm/year, and only 3 patients had an annual growth rate of above 3 mm/year. Conclusion    Mid- and long-term outcomes of RAA in adult patients undergoing AVR with both methods are satisfying and encouraging.

Objective:To evaluate the therapeutic effect of excimer laser ablation (ELA) in the treatment of lower extremity arterial ischemic diseases.Methods:The clinical data of 44 patients with lower extremity ischemic diseases treated with ELA in the People′s Hospital of Xinjiang Uygur Autonomous Region from December 2020 to April 2021 were analyzed retrospectively. Among the 44 patients, there were 29 patients in lower extremity arteriosclerosis obliterans (ASO), including 3 patients with femoral artery stent occlusion. 8 patients of diabetes foot (DF) and 7 patients of thromboangiitis obliterans (TAO). Observation indicators include target vascular patency rate, amputation rate, vascular reintervention rate and mortality rate. The measurement data were expressed as mean ± standard deviation ( ± s), one-way analysis of variance was used for inter-group comparison, and paired sample t-test was used for intra-group comparison. The Chi-square test was used for comparison between count data. Results:The success rate of operation was 100% in 44 patients. The rate of major amputation in ASO group was 10.3%, while the other two groups had a major amputation rate of 0. The minor amputation rates of the three groups were 6.9%, 25.0% and 28.6%, respectively. The vascular reintervention rate was 10.3% in ASO group, 12.5% in DF group and 0 in TAO group. The 1-year mortality rate in the ASO group was 10.3%, while the other two groups had a mortality rate of 0. The 2-year mortality rate of the three group were 31.0%, 12.5% and 0, respectively.Conclusion:For the treatment of lower extremity arterial ischemic diseases, ELA is safe and effective, but the curative effect need to further clarify by large sample and long-term clinical follow-up observation.

Objective:To explore the clinical efficacy of excimer laser atherectomy (ELA) in the treatment of diabetic foot with infrapopliteal arteriopathy.Methods:The clinical data of 36 patients (40 limbs) with diabetic foot complicated with inferior knee artery disease treated by ELA in Xinjiang Uygur Autonomous Region People′s Hospital from December 2019 to May 2021 were analyzed retrospectively. The success rate of ELA in the treatment of diabetic inferior genicular artery disease, ankle-brachial index (ABI), limb salvage rate and Visual Analogue Scale (VAS) score at 3 days and 3 and 6 months after operation was observed.Results:All the 36 patients were operated successfully, including 2 cases of flow-limiting dissection, 2 cases of arterial embolism and 1 case of hematoma at the puncture point. The ABI of patients 3, 6 months after operation was significantly higher than that before operation (all P<0.05), and the VAS score 3, 6 months after operation was significantly lower than that before operation (all P<0.05). The rate of limb (toe) salvage were 92.5%(37/40), 82.5%(33/40) at 3 d, 3 months and 77.5%(31/40) at 6 months after operation. Conclusions:ELA is safe and effective in the treatment of diabetic foot infrapopliteal arteriopathy, and the recent efficacy is fair.

The internal iliac artery originating from the common iliac artery is an important branch, and communicating with the branches of the abdominal aorta, such as lumbar artery and sacral median artery, forming rich collateral circulation and nourishing the blood supply of gluteal muscle and pelvic floor viscera. Surgical intervention is recommended when the maximum diameter of internal iliac artery aneurysms>2 cm. A variety of treatment modalities are available, particularly, endovascular technique has been successfully applied in the clinical treatment of internal iliac artery aneurysms, which can significantly improve the cure and reduce complications and deaths. This article reviews the previous literature and summarizes the progress of internal iliac artery aneurysms treatment.

Objective:To investigate the effect of interventional embolization of prostate artery in patients with benign prostatic hyperplasia with prostatic volume>80 ml.Methods:A total of 56 patients with BPH combined with hypertension, diabetesand heart disease with prostate volume>80 ml in Meizhou People′s Hospital from April 2018 to November 2020 were selected. They were divided into the study group and the control group according to a simple random number table, 28 cases in each group. The patients in the study group were performed prostatic arterial embolization, and the patients in the control group were performed transurethral resection of the prostate. The efficacy, perioperative conditions, preoperative and 1 month after operation serum total prostate specific antigen (TPSA) level, free prostate specific antigen (FPSA) level, prostate volume, and international prostate symptom score (IPSS) were compared between the two groups. The sexual life quality after operation for 6 months was compared between the two groups.Results:The efficacy of the two groups had no significant difference ( P>0.05). The intraoperative blood loss, postoperative catheterization, postoperative hospital stay in the study group were less than those in the control group: (10.65 ± 1.89) ml vs. (119.64 ± 23.60) ml, (2.16 ± 0.39) d vs. (3.05 ± 0.61) d, (3.03 ± 1.82) d vs. (7.10 ± 2.39) d, the differences were statistically significant( P<0.05). The levels of serum TPSA, FPSA and prostate volume, IPSS at the first month after surgery in the two groups had no significant differences ( P>0.05). After operation for 6 months, the scores of Chinese Index of Sexual Function for Premature Ejaculation-5 (CIPE-5) and International Index of Erectile Function (IIEF-5) in the study group were higher than those in the control group: (18.63 ± 2.51) scores vs. (15.71 ± 2.29) scores, (16.38 ± 4.14) scores vs. (13.98 ± 3.82) scores, the differences were statistically significant ( P<0.05). Conclusions:Prostate arterial embolization is effective in BPH patients with prostate volume>80 ml and underlying diseases. Compared with transurethral prostatectomy, it has the advantage of faster recovery after surgery, and it has an ideal effect in controlling diseases, improving urination function, and quality of sexual life.

Objective:To explore the strategies for the treatment of difficult iliac artery approach in endovascular repair of abdominal aortic aneurysm.Methods:The clinical data of 275 patients with abdominal aortic aneurysm who underwent endovascular surgery at the Department of Vascular Surgery, People′s Hospital of Xinjiang Uygur Autonomous Region from March 2010 to March 2019 were retrospectively analyzed, and the general clinical data such as age, gender, and comorbidities of the patients were recorded. The resource index was to carry out corresponding measures to perform surgery for patients with difficult access, analyze the incidence of the type of difficult access, treatment measures and effects.Results:Two hundred and seventy-five patients underwent endovascular repair, 78 of them (28.3%) had difficulty in accessing the iliac artery, including 29 cases (10.5%) with mild iliac artery stenosis, 7 cases (2.54%) with severe stenosis, and 3 cases with occlusion ( 1.09%), 39 cases (14.2%) were twisted. For patients with vascular twist, super-hard guide wire was used to correct iliac artery angulation. For patients with iliac artery stenosis, balloon dilation was performed. For severe stenosis, the artificial blood vessel was passed through the lateral peritoneum. After road transplantation, stent placement and other treatments were successfully performed endovascular repair.Conclusions:Pathway vascular disease can cause difficulties in endovascular treatment of abdominal aortic aneurysms. Endovascular repair can be successfully performed after corresponding treatments according to different difficulties, and the long-term patency rate is good.

Objective:To investigate the success rate, operation time and complications of ultrasound combined with X-ray-guided precise implantation of totally implantable access port (TIAP) in the chest wall.Methods:A total of 623 patients who underwent implantation of totally implantable venous access ports in the chest wall in Meizhou People's Hospital, China between January 2015 and August 2018 were included in this study. In group A ( n = 320), jugular or subclavian access ports were precisely implanted in the chest wall under the guidance of ultrasound combined with X-ray. During the surgery, color Doppler ultrasound was used to guide the puncture and a C-arm machine was used to locate the position of catheter tip. In group B ( n = 303), venous access ports were implanted using the conventional method. Subclavian vein puncture was performed using anatomic landmarks and the depth of catheterization was estimated by experience. The success rate of the first implantation, operation time, and complications (pneumothorax, hemothorax, catheter displacement, poor position of catheter tip, skin infection, and thrombosis) were compared between the two groups. Results:There were no statistical differences in baseline data between the two groups ( P > 0.05). The success rate of the first implantation in the group A was significantly higher than that in the group B [100% (320/320) vs. 93.06% (282/303), χ2 = 22.95, P < 0.01]. The operation time in the group A was significantly shorter than that in the group B [(26.48 ± 5.49) minutes vs. (35.51 ± 14.37) minutes, t = -10.25, P < 0.01]. In group A, 2 patients developed pneumothorax and healed after conservative treatment, 6 patients had thrombosis, and the incidence of complications was 2.5% (8/320). In group B, complications occurred in 67 patients, including pneumothorax in 9 patients, poor catheter tip position in 17 patients, thrombosis in 36 patients, and skin infection in 1 patient, and the incidence of complications was 22.11% (67/303). There was significant difference in the incidence of complications between the two groups ( χ2 = 56.53, P < 0.01). In group B, 6 out of 9 patients developing pneumothorax were healed after closed thoracic drainage, and 4 patients underwent a secondary surgery because of catheter displacement into the internal jugular vein. Conclusion:Precise implantation of venous access ports in the chest wall guided by ultrasound combined with X-ray has the advantages including 100% success rate of first precise implantation, few complications, short operation time, high comfort, safety and efficacy.
