Objective To evaluate the clinical significance of CT + MRI scans in diagnosis of primary liver cancer and prognosis evaluation after interventional therapy. Methods A total of 150 cases of patients with primary liver cancer admitted to our hospital from January 2019 to January 2021 were selected. They all received interventional treatment, and were examined by CT and MRI. The results of pathological examination were taken as the gold standard in this study to compare the diagnostic efficacy of CT, MRI and CT+MRI.Kappa value was used to compare the consistency of CT, MRI, CT+MRI scans with gold standard, and compared the detection rate of lesions after CT, MRI and CT+MRI interventional surgery. Results The diagnostic accuracy (98.67%), specificity (75.00%) and sensitivity (99.32%) of CT + MRI scans were higher than those of CT (86.00%, 25.00%, 87.67%) and MRI scans (90.67%, 91.78%, 50.00%),P<0.05 (which differences were statistically significant). The consistency of CT + MRI scans with gold standard was good (kappa value was 0.779), but the consistency of CT/MRI scans with gold standard were not satisfying (kappa value were 0.527, 0.596). The total detection rate of lesions after CT + MRI interventional surgery (12.00%) was higher than that of CT (2.00%) and MRI (4.00%, which P<0.05). Conclusion CT + MRI scans can improve the detection rate of lesions in patients with primary liver cancer after interventional therapy, and make up for the deficiency of only CT or MRI scans.

Objective To evaluate the value of ultrasonography scoring system in differential diagnosis of well-differentiated liposarcomas (WDLPS) and benign lipoma (LP), and to provide evidence for the differential diagnosis and treatment choice. Methods Fourteen WDLPS cases (total of 15 masses) and 37 LP cases (total of 40 masses) were diagnosed by surgical histopathology, which clinical data and the ultrasound images were analyzed retrospectively. The parameters including age, gender, region, mass length, length/width ratio, shape, margin, envelope echoes, echogenicity, texture, location, blood flow were compared between the groups above. A scoring system was established by analyzing the parameters with statistical differences, and the ROC curve was plotted to calculate the best cut-off value and evaluate the diagnostic efficiency of the scoring system. Results There were statistically significant differences between two groups in the following six parameters: age, mass length, length/width ratio, envelope echoes, location, blood flow(P＜0.05). The scoring system was established by assigning 0 or 1 point to each factor, and the total score was 0～6 points. The highest diagnostic efficiency of WDLPS was observed at the cut-off value ≥ 3. The sensitivity, specificity, accuracy, the positive predictive value and the negative predictive value was 86.7%, 77.5%, 80%, 59.1%, 93.9% respectively. Conclusions The ultrasonography-based scoring system has a better diagnostic efficacy in differentiating WDLPS and LP, which can provide an important reference basis for the selection of clinical treatment, and is worthy of promotion and application.

目的 对比剖宫产术后子宫瘢痕妊娠(CSP)与对照组的相关数据,为及早诊断CSP提供帮助;对比不同超声分型CSP超声特征及治疗方式,为早期诊断和个体化治疗方案的制定提供客观依据。方法 回顾性分析我院收治的41例CSP患者及41例对照患者的超声声像图特征及相关临床指标,总结分析不同分型CSP患者所采取的治疗方式。结果 41例CSP患者与41例对照组比较,出现阴道流血的概率更高,差异有统计学意义(P<0.05);根据超声分型将CSP分为4型,分别为Ⅰ、Ⅱ、ⅢA及ⅢB型,Ⅰ型CSP患者与其他3型CSP比较,出现阴道流血的概率要高,差异有统计学意义(P<0.05);Ⅰ型CSP较Ⅱ、Ⅲ、ⅢA型子宫前壁肌层厚,差异有统计学意义(P<0.05);关于治疗:Ⅰ型CSP主要治疗方式为超声引导清宫术;Ⅱ型根据临床实际情况,每一种方式都可选择;Ⅲ型CSP主要采用子宫动脉栓塞后超声引导下清宫术,所有患者术中出血均不多,预后良好并顺利出院。结论 1.CSP患者与对照组临床指标对比有一定差异性,但不够特异,故为了及早的诊断CSP,对于有剖宫产史妇女再次妊娠的早孕检查,一定要明确妊娠囊与子宫前壁下段瘢痕及膀胱的关系;2.超声分型有助于制定针对CSP的个体化治疗方案,以改善患者预后。故诊断CSP的同时,还需对CSP进行准确的超声分型。

Objective To compare the data of cesarean scar pregnancy (CSP) after cesarean section with that of the control group, so as to provide help for the early diagnosis of CSP. To compare the ultrasonic characteristics and treatment methods of different ultrasonic types of CSP, so as to provide an objective basis for early diagnosis and individualized treatment. Methods The ultrasonographic features and related clinical indexes of 41 CSP patients and 41 control patients were analyzed retrospectively, the treatment methods adopted by patients with different types of CSP were summarized and analyzed. Results The probability of vaginal bleeding in 41 patients with CSP was higher than that in 41 control patients, the difference was statistically significant (P<0.05). According to ultrasonic classification, CSP is divided into four types: Ⅰ, Ⅱ, ⅢA and ⅢB. Compared with other 3 types CSPs, patients with type Ⅰ CSP had higher probability of vaginal bleeding, which difference was statistically significant (P<0.05). The main treatment of type Ⅰ CSP was ultrasound-guided uterine curettage, each method could be selected according to the actual clinical situation for type Ⅱ CSP, type Ⅲ CSP mainly adopted ultrasound-guided uterine curettage after uterine artery embolization. All patients had little intraoperative bleeding, good prognosis and been discharged successfully. Conclusions There were some differences in clinical indexes between CSP patients and control patients, but they were not specific enough. Therefore, in order to diagnose CSP as soon as possible, for the early pregnancy examination of second pregnancy in patients with cesarean section, we must clarify the relationship between gestational sac and scar of the lower part of the anterior wall of uterus and bladder. Ultrasound typing is helpful to formulate an individualized treatment plan for CSP patients to improve the prognosis. Therefore, accurate ultrasonic typing is also needed when diagnosing CSP.

Objective To explore the clinical diagnostic value of serum bilirubin and uric acid detection in patients with coronary heart disease. Methods A total of 100 patients with coronary heart disease from June 2020 to June 2021 were selected as the observation group, and another 100 healthy subjects in the same period were selected as control group. Serum bilirubin and uric acid levels were detected and compared between the two groups. Meanwhile, the patients in the observation group were divided into groups A, B, C and D according to the degree of coronary artery stenosis (Gensini method). The changes of the above indexes were compared among different grades of coronary stenosis. And the diagnostic efficacy of each single detection and combined detection of serum bilirubin and uric acid in patients with coronary heart disease were evaluated and compared. Results Compared with the control group, the serum bilirubin (total bilirubin, direct bilirubin, indirect bilirubin) level of the observation group was lower, and the uric acid level was higher, with statistical differences (P<0.05). With the increased severity of coronary artery stenosis, the serum bilirubin level of patients showed a downward trend, while the uric acid level showed an upward trend, and there were significant differences among the four groups (P<0.05). The sensitivity and specificity of serum bilirubin combined with uric acid detection in patients with coronary heart disease were 96.00% and 95.00% respectively, which were higher than those of single detection (P<0.05). Conclusions Serum bilirubin and uric acid levels can be used as sensitive indicators in the diagnosis of patients with coronary heart disease, and are closely related to the occurrence and development of coronary heart disease, which can reflect the severity of the disease, also the diagnostic value of combined detection is higher.

Objective To compare the effects of the 2012 and 2007 American Academy of Sleep Medicine (AASM₂₀₁₂ and AASM₂₀₀₇) scoring criteria on the diagnosis, sleep and clinical characteristics of chronic obstructive pulmonary disease (COPD) with obstructive sleep apnea (OSA). Methods AASM₂₀₀₇ and AASM₂₀₁₂ were used to analyze the sleep respiratory events of 41 patients with stable COPD. Differences in apnea-hypopnea index (AHI) and diagnosis of OSA in COPD patients between AASM₂₀₀₇ and AASM₂₀₁₂ criteria were compared. Differences in sleep parameters and clinical indexes were compared between patients with overlap syndrome who met the AASM₂₀₁₂ not AASM₂₀₀₇ criteria (OS_2012-2007) and COPD patients who only met the AASM₂₀₀₇ criteria (COPD_AASM2007). Results Using the AASM₂₀₁₂ criteria, the number of AHI [1.0 (1.0, 7.5) h^-1 vs 11.5 (4.1, 25.1) h^-1, P<0.001] and the proportion complicated with OSA (36.6% vs 70.7%, P<0.05) significantly increased compared to the AASM₂₀₀₇ criteria. There was a significant difference between OS_2012-2007 and COPD_AASM2007 in arousal index and third stage of sleep, but no significant difference in other sleep parameters, blood pressure and the number of patients with hypertension. Conclusions Using AASM₂₀₁₂ significantly increased AHI and the proportion complicated with OSA in COPD patients, but the preliminary results demonstrated that pathological damages of OS_2012-2007 were relatively mild.

Objective To investigate the clinical value of p16/Ki-67 staining E6/E7 mRNA and combined detection in the diagnosis of HSIL+ lesions. Methods From March 2017 to August 2020,209 cases of cervicitis,169 cases of LSIL,131 cases of HSIL and 86 cases of cervical cancer confirmed by histology were selected as the research objects. The results of p16/Ki-67 staining and HPV E6/E7 RNA detection of the preoperative cytological samples were retrospectively analyzed and the p16/Ki-67 staining and HPV E6/E7 mRNA detection results were compared longitudinally. The positive rates of E6/E7mRNA and combined detection in different grades of cervical lesions were compared.The positive rates of p16/Ki-67 staining,HPV E6/E7 mRNA and combined detection in the same cervical lesions were compared horizontally.The differences in the diagnostic efficacy of p16/Ki-67 staining,HPV E6/E7 mRNA and combined detection in the diagnosis of HSIL+lesions were comprehensively evaluated. Results ①Longitudinal comparison:the positive rates of p16/ Ki-67 staining, HPV E6/E7mRNA and combined detection increased with the severity of cervical lesions(p16/Ki-67 staining:χ²=374.34,P<0.001;HPV E6/E7 mRNA detection:χ²=289.21,P<0.001;joint detection:χ²=343.90,P<0.001). ②Transverse comparison: in cervicitis, LSIL and cervical cancer groups,there were no significant differences in the positive rates of p16/Ki-67 staining, HPV E6/E7 mRNA and combined detection (all P>0.05). In the HSIL group,there was significant difference in the positive rate between p16/Ki-67 staining and combined detection (χ²=8.09,P=0.004)and the difference between HPV E6/ E7 mRNA and combined detection was statistically significant(χ²=11.30,P=0.001). ③The sensitivity of p16/Ki-67staining,HPV E6/E7 mRNA and combined detection in the diagnosis of HSIL+ was statistically significant(χ²=7.69,P=0.021). The sensitivity difference between p16/Ki-67 staining and combined detection was statistically significant(χ²=7.29,P=0.007);the sensitivity difference between HPV E6/E7 mRNA detection and combined detection method was statistically significant (χ²=4.84,P=0.028). There was no significant difference in the specificity and coincidence rate of p16/Ki-67 staining,HPV E6/E7 mRNA and combined detection in the diagnosis of HSIL+(χ²₁=5.38,P₁=0.068;χ²₂=0.93,P₂=0.628). Conclusion P16/Ki-67 staining,HPV E6/E7 mRNA and combined detection may effectively screen out HSIL+ lesions,reduce the missed diagnosis rate, but the combined detection may significantly improve the sensitivity of diagnosis of HSIL+ lesions, while maintaining good specificity and coincidence rate.It is suggested that p16/Ki-67 staining and HPV E6/E7 mRNA detection should be used as a strategy for early diagnosis of HSIL+ lesions.
