【摘要】 目的 分析慢性乙肝患者血清生化、血常规、血清病毒载量及乙型肝炎标志物与肝组织炎症分级、纤维化分期的相关性,以找到有较好相关性的临床指标；通过肝活检证实临床诊断与病理诊断的符合情况,探讨肝活检的重要性及价值。方法 对2007年6月—2009年8月在传染科行肝穿刺活检的359例慢性乙型肝炎患者的血清丙氨酸氨基转移酶(ALT)、门冬氨酸氨基转移酶(AST)、总胆红素(TB)、白蛋白(ALB)、球蛋白(GLB)等指标,白细胞(WBC)、血小板(PLT)等指标,凝血酶原时间(PT),血清HBV DNA定量及乙肝标志物的不同状态与肝穿病理分级、分期的相关性进行分析；统计慢性乙肝患者临床诊断与病理诊断的符合情况。结果 肝组织炎症分级及纤维化分期之间有一定相关性(Plt;0.05)；血清ALT、AST、ALB、GLB、PT有助于判断肝组织炎症程度(Plt;0.05)；ALB、GLB、WBC、PLT、PT对肝组织纤维化程度的评估有意义(Plt;0.05)；HBV DNA复制水平与肝组织炎症及纤维化无关(Pgt;0.05),但存在负相关的趋势；纤维化程度高的患者HBeAg阴性组较HBeAg阳性组更多(Plt;0.05)。慢性乙型肝炎患者临床与病理诊断总符合率为56.3％。结论 动态监测慢性乙肝患者肝功能、血常规、凝血常规在一定程度上有助于判断疾病的程度,但要确诊肝组织炎症分级及纤维化分期,肝组织病理活检是必需的。
Objective To investigate the tumor suppressor genes of phlegm DNA in smokers, and analyze the correlation between methylation level of tumor suppressor gene promoter and chronic mucus hypersecretion (CMH). Methods The study recruited the patients who were admitted in the respiratory department during 2013-2016 in this hospital, including 700 cases of urban smokers and 380 cases of rural smokers. Eleven genes commonly silenced by promoter methylation in lung cancer and associated with cancer risk were selected. Methylation specific PCR (MSP) was used in the sputum sample of 700 individuals in the urban smokers cohort. Replication was performed in 380 individuals from the rural smokers cohort. Results CMH was significantly associated with an overall increased number of methylated genes, with SULF2 methylation demonstrating the most consistent association. The association between SULF2 methylation and CMH was significantly increased in males but not in females both in the urban and rural groups (OR=2.73, 95%CI 1.53-4.93, P=0.001; OR=2.96, 95%CI 1.47-5.94, P=0.002, respectively). Furthermore, the association between methylation and CMH was more obvious among 139 male former smokers with persistent CMH compared with current smokers (SULF2, OR=3.64, 95%CI 1.57-8.35, P=0.002). Conclusion These findings demonstrate that especially male former smokers with persistent CMH have markedly increased promoter methylation of lung cancer risk genes and potentially could be at increased risk for lung cancer.
ObjectiveTo investigate the effects of closed thoracic drainage with single tube or double tubes after video-assisted thoracoscopic lung volume reduction surgery.MethodsRetrospective analysis was performed on 50 patients (39 males, 11 females) who underwent three-port thoracoscopic lung volume reduction surgery in our hospital from January 2013 to March 2019. Twenty-five patients with single indwelling tube after surgery were divided into the observation group and 25 patients with double indwelling tubes were divided into the control group.ResultsThere was no significant difference in pulmonary retension on day 3 after surgery, postoperative complications, the patency rate of drainage tube before extubation, retention time or postoperative hospital stay (P>0.05). Postoperative pain and total amount of nonsteroidal analgesics use in the observation group was less than those in the control group (P<0.05). ConclusionIt is safe and effective to perform closed thoracic drainage with single indwelling tube after video-assisted thoracoscopic lung volume reduction surgery, which can significantly reduce the incidence of related adverse drug reactions and facilitate rapid postoperative rehabilitation with a reduction of postoperative pain and the use of analgesic drugs.

Objective To analyse the content and structure of the health management policy text for chronic obstructive pulmonary disease (COPD) in China, and to provide a reference for the optimization and improvement of subsequent relevant policies. Methods We searched for relevant policy documents on COPD health management at the national level from January 2017 to December 2023, constructed a two-dimensional analysis framework for policy tools and chronic disease health management processes, coded and classified policy texts, and used content analysis method to analyze policy texts. Results Twenty-four policy texts were included. There were 183 codes for policy tool dimension, with supply based, environmental based, and demand based tools accounting for 43.72%, 47.54%, and 8.74%, respectively. There were 124 codes for the dimension of health management processes, with health information collection and management accounting for 12.10%, risk prediction accounting for 14.52%, intervention and treatment accounting for 66.13%, and follow-up and effectiveness evaluation accounting for 7.26%. Conclusions At present, the proportion of policy tools related to the management of COPD in China needs to be dynamically adjusted. Environmental tools should be appropriately reduced, the internal structure of supply tools should be optimized, the driving effect of demand tools should be comprehensively enhanced, the coupling of COPD health management processes should be strengthened, and the relevant policy system and overall quality should be continuously improved.
ObjectiveTo summarize the current status and progress of the treatment of chronic lateral ankle instability (CLAI). MethodsThe literature about the anatomical repair of CLAI at home and abroad was reviewed and summarized. ResultsBroström and its modified operations are the most common surgical treatment of CLAI. The operations showed satisfactory clinical outcomes in the short-, medium-, and long-term follow-up and low complication rate. Suture anchor technique and arthroscopic techniques are gradually used in Broström and its modified operations with satisfactory short-term effectiveness, but long-term effectiveness needs further observation because of the limitation of the short clinical application time. ConclusionBroström and its modified operations are effective, convenient, and safe to treat CLAI. Based on the researches of biomechanics and dynamic anatomy, the more personalized design of the rehabilitation program is the further research direction.
【Abstract】ObjectiveTo compare the reliability of acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) and APACHE Ⅲ to estimate mortality of critical patients in abdominal surgery. MethodsTwo hundred and sixtyone critical patients in abdominal surgery were included in this study. The clinical data of the first day in ICU were collected and evaluated with both APACHE Ⅱand APACHE Ⅲ prognostic systems and statistical analysis were performed. Probability of survival (Ps) was compared with actual mortality. ResultsThe scores of APACHE Ⅱ and APACHE Ⅲ of death group were significantly higher than those of survival group respectively (P＜0.01). The actual mortality of patients whose Ps was no more than 0.5 was higher than that whose Ps was over 0.5 (P＜0.01). With two prognostic systems, the scores and mortality were the highest in pancreatitis patients and the lowest in patients with gastrointestinal malignant tumor. ConclusionAPACHE Ⅱ and APACHE Ⅲ prognostic systems can be effectively applied to the estimation of mortality of critical patients in abdominal surgery. For certain diagnostic categories, APACHE Ⅲ is better than APACHE Ⅱprognostic system.
Objective To study polyuria during mechanical ventilation in patients with chronic obstructive pulmonary disease ( COPD) and its possible mechanisms. Methods The plasma and urine concentrations of cystatin C ( CyC) were measured by enzyme immunometric assay in 26 COPD patients who received mechanical ventilation at timepoints of 0 h, 24 h, 48 h, 72 h and 1 week. And plasma levels of atrial natriuretic factor ( ANF ) , antidiuretic hormone ( ADH) and aldosterone ( ALD) were detected byradioimmunoassay at the same time-point. The urine volume was recorded every day. The samples of 30 healthy volunteers were measured as control. Results Polyuria phenomenon was found in majority of patients in 24 to 72 hours after mechanical ventilation. At 0h, the concentrations of plasma CyC, urine CyC,plasma ANF, ADH and ALD were all increased significantly compared with those of the control, respectively [ ( 4. 87 ±0. 51) mg/L vs ( 1. 29 ±0. 27) mg/L, ( 0. 58 ±0. 13) mg/L vs ( 0. 07 ±0. 02) mg/L, ( 37. 02 ±4. 35) pmol /L vs ( 22. 51 ±1. 18) pmol /L, ( 8. 61 ±1. 43) pmol /L vs ( 0.94 ±0. 34) pmol /L, ( 925. 4 ±142. 7) pmol /L vs ( 297. 5 ±135. 8) pmol /L, all P lt; 0. 01] , then decreased gradually after mechanical ventilation. The levels of plasma CyC and ANF at 24 h, plasma ADH at 72 h, and urine CyC at 1 week were similar to those of the control( all P gt;0. 05) , respectively, except the level of plasma ALD was still higher by 1 week( P lt; 0. 05) . Conclusions Polyuria is not a rare phenomenon for COPD patients receiving mechanical ventilation. Polyuria is related to the readjustment and mal-adaptation of ADH and reninangiotensin-aldosterone-systems during mechanical ventilation.
