ABSTRACT

ObjectiveTo compare the effectiveness and safety of one-lung ventilation and small tidal volume two-lung ventilation anesthesia methods in the training of minimally invasive thoracic surgery on experimental pigs.MethodsForty experimental pigs undergoing robotic thoracic surgery were randomly divided into two groups: two-lung ventilation group (n=20) and one-lung ventilation group (n=20). The two-lung ventilation group underwent single-lumen tracheal intubation, utilizing a small tidal volume with a fast respiratory rate combined with carbon dioxide pneumothorax for anesthesia ventilation during the operation. The one-lung ventilation group received one-lung ventilation using a double-lumen bronchial catheter placed under fiberoptic bronchoscopic guidance. The anesthesia implementation indexes from the two groups were compared, including the values of vital signs such as operative heart rate (HR), noninvasive mean blood pressure (MAP), end-tidal carbon dioxide (ETCO2), and oxygen saturation (SpO2), as well as the assessment of surgical training performance.Results The intubation success rate for animals in both groups was 100%, with no intraoperative deaths. The intubation completion time was significantly shorter in the two-lung ventilation group compared to the one-lung ventilation group (P < 0.001). Within each group, SpO2 levels were significantly higher in the two-lung ventilation group at 30 minutes after the start of thoracic surgery (T1) and at surgery completion (T3) compared to 60 minutes after the start of surgery (T2) (P<0.05). ETCO2, HR, and MAP were significantly higher at T2 and T3 compared to T1 (P<0.05). In the one-lung ventilation group, SpO2 levels were significantly higher at T1 and T3 compared to T2 (P<0.05), while ETCO2 levels gradually increasing over time (P<0.05). In the between-group comparisons at the same time points, SpO2 levels of the two-lung ventilation group were significantly higher than those of the one-lung ventilation group at all time points (T1, T2, T3) (P<0.05).Conclusion Both one-lung ventilation and two-lung ventilation anesthesia methods are effective and safe for use in surgical training, with controllable effects on intraoperative animal vital signs and minimal impact on surgical operation training, meeting the needs of robotic thoracic surgery training. One-lung ventilation provides a better experience during pneumonectomy procedures, while small tidal volume two-lung ventilation is easier to implement and does not require additional equipment purchase, making it a feasible supplemental anesthesia option for thoracoscopic surgery on experimental pigs.

ABSTRACT

ObjectiveTo evaluate the clinical efficacy of Qimai Qinlou prescription in the treatment of elderly community-acquired pneumonia (CAP) (non-severe) with Qi and Yin deficiency and phlegm-heat obstructing lung syndrome and its impact on immune-inflammatory factors. MethodA total of 120 eligible patients were randomly divided into an observation group (60 cases) and a control group (60 cases). Both groups received intravenous cefoxitin sodium. In addition, the observation group received oral Qimai Qinlou prescription, while the control group received an oral placebo simulating Qimai Qinlou prescription. The treatment course was 14 days. The disappearance time of major clinical symptoms and signs was recorded. Traditional Chinese medicine (TCM) syndrome scores and the Clinical Research Outcome (CAP-CRO) scale scores for pneumonia of the two groups were compared. Chest computed tomography (CT) scans were performed, and peripheral blood levels of procalcitonin (PCT), interleukin-6 (IL-6), serum amyloid A (SAA), high-sensitivity C-reactive protein (hs-CRP), CD4+, CD8+, and CD4+/CD8+ were measured. The conversion rate to severe condition during hospitalization, readmission rate within 30 days after discharge, and safety evaluation were recorded. ResultAfter treatment, the observation group showed significantly shorter time of fever, cough, expectoration, and disappearance time of lung moist rales than the control group (P<0.01). The TCM syndrome scores, CAP-CRO scores in all dimensions, and total scores in both groups were significantly reduced as compared with those before treatment (P<0.01). After treatment, the observation group had a more significant reduction than the control group (P<0.01). The levels of PCT, IL-6, SAA, and hs-CRP in both groups were significantly reduced as compared with those before treatment (P<0.01). After treatment, the observation group showed a more significant reduction than the control group (P<0.01). There was no statistically significant difference in the changes of CD4+, CD8+, and CD4+/CD8+ in the control group before and after treatment. However, in the observation group, CD4+ and CD4+/CD8+ levels significantly increased (P<0.01), while CD8+ level significantly decreased (P<0.01) after treatment. After treatment, CD4+ and CD4+/CD8+ in the observation group significantly increased (P<0.01), and CD8+ significantly decreased as compared with those in the control group (P<0.01). At 7, 10, and 14 days after treatment, the curative rates in the observation group were 53.33% (32/60), 85.00% (51/60), and 91.67% (55/60), respectively, which were higher than 31.67% (19/60), 61.67% (37/60), and 68.33% (41/60) in the control group (χ2=5.763, 8.352, 10.208, P<0.05). After treatment, the total effective rate of CT scanning in the observation group was 93.33% (56/60), higher than 80.00% (48/60) in the control group (χ2=4.615, P<0.05). The conversion rate to severe condition during hospitalization in the observation group was 3.33% (2/60), lower than 15.00% (9/60) in the control group (χ2=4.904, P<0.05). The readmission rate within 30 days after discharge in the observation group was 8.33% (5/60), lower than 23.33% (14/60) in the control group (χ2=5.065, P<0.05). No serious adverse drug reactions were observed in either group during the treatment period. ConclusionQimai Qinlou prescription can enhance immune function, alleviate inflammatory reactions, significantly relieve clinical symptoms, shorten the duration of the disease, improve the curative rate and CT scanning efficacy, prevent disease progression, reduce the readmission rate in the short term, and is clinically safe for the treatment of elderly patients with non-severe CAP with Qi and Yin deficiency and phlegm-heat obstructing lung syndrome. It is worthy of further research and application.

ABSTRACT

Osteosarcoma(OS)is a malignant tumor that occurs mostly in children and adolescents with a poor prognosis. The 5-year survival rate and the survival rate of patients with lung metastasis or distant metastasis are still unsatisfactory. Currently,the treatment of osteosarcoma is still unsatisfactory under the bottleneck period. Long-chain non-coding RNA(LncRNA)is a non-pro-tein-encoding RNA molecule involved in a variety of processes including gene expression,chromatin remodeling,post-transcription-al processing and transcription. LncRNAs are abnormally expressed in human cancers and they are involved in tumor development, progression and metastasis. This article reviews the research progress of long-chain non-coding RNA in osteosarcoma,which is in-tended to provide further research for osteosarcoma and propose new diagnosis and treatment strategies.

ABSTRACT

Objective To retrospectively investigate the causes , location and the duration of hospital stays of the hospitalized patients with hard-to-heal wounds so as to provide data guidance for the prevention and research of these diseases. Methods Clinical data of hospitalized patients with hard-to-heal wounds in plastic surgery center of General Hospital of Guangzhou Military Command were collected from June , 2011 to December, 2013. Whether ulceration was recovered in the patients with skin tissue defect after 2 months treatment was regarded as the standard to screen the patients with hard-to-heal wounds. The causes , location, age and the duration of hospital stays of the hospitalized patients with hard-to-heal wounds were investigated by retrospective case-control method. Chi-square test and t-test were used in analyzing the investigation. Results 2 136 cases, aged from 20 to 86, were treated in plastic surgery center of the hospital. 120 cases have hard-to-heal wounds, which constituted 5.62% of all hospitalized patients. (1) Metabolic disease was the main causes of wound (43.3%), followed by wound infection and tumor (20.0% for each) (χ2 = 62.917, P < 0.01). ( 2 ) The peak age for patients with hard-to-heal wounds was 40 to 60 years old patients , followed by patients′age from 60 to 80 years. (3) The mostly like hard-to-heal wounds was on limbs (61.6%), especially on the foot (38.3%) (χ2 = 17.546, P = 0.002). (4) The average days for hospitalization of in the plastic surgery center were (7.41 ± 8.98), while the average days for hospitalization of the patients with years were (33.21 ± 28.27)(t = -9.968, P < 0.05). Conclusion The average diagnostic age of patients with hard-to-heal wounds is the middle and old aged patients. Chronic skin ulcers, which often occurs in a limb, seriously affects a person′s ability to move , which can prolong hospital stays , causing serious burden for the families of patients and the society.
