目的 观察两种手术方式治疗翼状胬肉的临床效果。 方法 对2007年1月－2012年6月一般情况较好的73例单纯原发性双眼翼状胬肉患者进行了回顾性研究，比较同一患者双眼分别行翼状胬肉切除+生物羊膜移植（左眼）和翼状胬肉切除+自体角膜缘干细胞移植（右眼）手术后痊愈率、复发率及并发症。 结果 行翼状胬肉切除+自体角膜缘干细胞移植（右眼）的痊愈率达93.15%，复发率1.37%，并发症率5.48%，其痊愈率更高而复发率及并发症均更低。 结论 翼状胬肉切除+自体角膜缘干细胞移植用于治疗翼状胬肉比翼状胬肉切除+人工羊膜移植的疗效更好，值得临床推广。
ObjectiveTo analyze the postoperative drainage volume and its influencing factors in lumbar posterior surgery.MethodsA total of 158 patients undergoing lumbar posterior surgery in West China Hospital, Sichuan University between October 2018 and June 2019 were retrospectively enrolled in this study. The data about general information and perioperative drainage were collected retrospectively according to recording tables and analyzed by SPSS (version 22) software. The drainage volume was presented with median (lower quartile, upper quartile).ResultsThe final average drainage volume was 360 (200, 650) mL, and the length of time for drainage tube placement was from 9 to187 hours with the median (lower quartile, upper quartile) of 61 (40, 86) hours. The result of multiple linear regression showed that immediate drainage volume when returning to the ward [non-standardized partial regression coefficient (b)=0.268, 95% confidence interval (CI) (0.191, 0.345), P<0.001], length of time for drainage tube placement [b=0.554, 95%CI (0.338, 0.769), P<0.001], intra-operative bleeding volume [b=0.161, 95%CI (0.044, 0.277), P=0.007], and surgical methods [Method 3 as the reference, Method 1: b=0.599, 95%CI (0.369, 0.828), P<0.001; Method 2: b=0.574, 95%CI (0.336, 0.812), P<0.001] were the main factors affecting the final drainage volume.ConclusionsThe final drainage volume of lumbar posterior surgery is so large that it should be paid attention to. It is also necessary to take effective interventions according to different surgical methods, intraoperative bleeding, immediate drainage when returning to the ward, length of time for drainage tube placement, and other different circumstances to reduce the drainage to achieve enhanced recovery after surgery.
Objective To evaluate the relation of human immunodeficiency virus (HIV)-1 ribonucleic acid (RNA) loads in cerebrospinal fluid with central neurological diseases. Methods The inpatients with HIV-1 infection diagnosed by Public Health Clinical Center of Chengdu between January 1st, 2015 and March 1st, 2018 were retrospectively included. The included patients were divided into central neurological disease group and non-central neurological disease group, and high viral load group and low viral load group. The demographic data, CD4+ T lymphocyte count, routine detection of cerebrospinal fluid, HIV RNA load in cerebrospinal fluid and plasma of patients with and without central neurological diseases were observed and compared.Multiple logistic regression analysis was used to identify risk factors for central neurological diseases. Results A total of 367 patients were included. In the central neurological disease group, 210 cases (57.22%) were complicated with central neurological diseases, and cryptococcus infection was the most. Compared with the non-central neurological disease group, the increase rate of cerebrospinal fluid cell counts, cerebrospinal fluid cell counts, cerebrospinal fluid HIV RNA positivity and cerebrospinal fluid HIV RNA load were higher in the central neurological disease group (P<0.05). Logistic regression analysis showed that HIV RNA load in cerebrospinal fluid≥100 000 copies/mL and CD4+ T lymphocyte count<200 cells/mm3 were risk factors for central neurological diseases. Conclusion Cerebrospinal fluid HIV RNA load≥100 000 copies/mL is an independent risk factor for HIV/AIDS patients with central neurological diseases and clinical treatment should take this factor into consideration to reasonably optimize the selection of antiretroviral therapy.
Objective To compare the perioperative outcomes of atypical segmentectomy between robotic-assisted thoracoscopic surgery (RATS) and conventional video-assisted thoracoscopic surgery (VATS) in early-stage non-small cell lung cancer (NSCLC). MethodsThe data of patients who underwent minimally invasive anatomic atypical segmentectomy in our hospital from October 2016 to December 2021 were collected. These patients were divided into a RATS group and a VATS group according to the operation method. Propensity score (PS) matching was used to select patients with close clinical baseline characteristics, and the perioperative results of the two groups were compared. ResultsA total of 1 048 patients were enrolled, including 320 males and 728 females, with a mean age of 53.51±11.13 years. There were 277 patients in the RATS group and 771 patients in the VATS group. After 1∶1 PS matching, 277 pairs were selected. Both groups were well balanced for age, sex, smoking history, body mass index, Charlson comorbidity index, pulmonary function, tumor size, tumor location, and histological type. All patients were R0 resection, and there were no deaths within 30 days after surgery. The RATS group had shorter operative time [85 (75, 105) min vs. 115 (95, 140) min, P<0.001] and less blood loss [50 (30, 100) mL vs. 60 (50, 100) mL, P=0.001]. There were no statistical differences between the two groups in lymph node resection, conversion to thoracotomy, thoracic drainage time, total amount of thoracic drainage or postoperative complications (P>0.05). ConclusionBoth RATS and VATS atypical segmentectomies are safe and feasible for early-stage NSCLC. RATS can effectively shorten the operative time, and reduce blood loss.
