BACKGROUND: Intestinal tract factors, especially intestinal ischemiareperfusion, can induce the injury of remote organ. Chinese herb, rhubarb,can clear oxygen free radical to promote the proliferation of beaker cell in intestinal mucous membrane, inhibit excessive multiplication of bacterium and endotoxin absorption in the intestinal tract, activate blood circulation and remove blood stasis, improve microcirculation and other ways to protect intestinal mucous membrane barrier, so as to prevent and treat pulmonary injury.OBJECTIVE: To observe the preventing and treating effect of rhubarb on intestinal ischemia/reperfusion-induced pulmonary injury and the effect of rhubarb on tumor necrosis factor and phospholipase A2 (PLA2).DESIGN: A randomized controlled observation.SETTING: Department of Emergency, Urumqi General Hospital of Lanzhou Military Area Command of Chinese PLA.MATERIALS: This experiment was carried out in the Second Military Medical University of Chinese PLA from February to July 2003. Totally 80SD rats were selected and randomly divided into intestinal ischemia/reperfusion group (n=24), sham operation group (n=46), treatment group (n=24) and normal saline group (n=16).METHODS: In the intestinal ischemia-reperfusion group, rats were fasted before operation. They were anesthetized and given a median abdominal incision. Superior mesenteric artery was isolated and occluded by vascular clamp without wound, and then the incision was sutured; 45 minutes later,vascular clamp was taken out to recover blood supply. For the treatment group, modeling was the same as that in the intestinal ischemia/reperfusion group, 600 mg/kg suspension of rhubarb extract was gastrointestinally perfused into the rats 30 minutes before recovering blood supply. For the normal saline group, modeling was the same as that in the intestinal ischemia/reperfusion group; same dosage of normal saline was gastrointestinally perfused into the rats 30 minutes before recovering blood supply. For the sham operation group, occlusion of superior mesenteric artery was omitted. Taking pathological change and 125I-labeled bovine serum albumin pulmonary uptake index as the index to evaluate pulmonary injury, TNF content and serum of pulmonary tissue and PLA2 activity of lung and intestinal tissue of animals in each group were measured respectively at different time points.MAIN OUTCOME MEASURES: 125I labeled bovine bovine serum albumin uptake index, tumor necrosis factor content of blood and pulmonary tissue, and PLA2 activity of serum, lung and intestinal tissue RESULTS: ① Pathological and morphological change of pulmonary tissue: There was no obvious abnormality in the sham operation group; In the intestinal ischemia-reperfusion group, 6 hours later, pulmonary interstitial edema, neutrophile infiltration appeared and alveolar edema was also found, and there were a little haemorrhage and exudation of fibrin. Only mild pulmonary interstitial edema and a small quantity of neutrophiles were found in the treatment group. ② Ultramicro-pathological change of pulmonary tissue: There was no obvious change in the sham operation group. In the intestinal ishcemia/reperfusion group, 6 hours later, pulmonary capillary endothelial cells were swelled and neutrophilic granulocyte leaked into pulmonary stroma and alveolar space. There were no above changes in the treatment group. ③ Change of tumor necrosis factor of pulmonary tissue in the sham operation group or treatment group (reperfusion for 30 minutes) was significantly lower than that in the intestinal ischemiareperfusion group (reperfusion for 30 minutes) (0.235±0.114,1.374±0.550,16.315±4.587,P < 0.01). ④125I-BSA pulmonary uptake index in the treatment group was significantly lower than that in the intestinal ischemiareperfusion group and normal saline group (P < 0.01), without significant difference in comparison with sham operation group (P > 0.05).CONCLUSION: Early application of rhubarb is helpful to prevent and treat lung injury following small intestine ischemic reperfusion, so as to inhibit tissue disease course to deve1op multiple organ dysfunction syndrome,which might be implemented through inhibiting the release of TNF and PLA2 and other media.

Objective To compare the inspiratory cycling-off synchronization with expiratory trigger sensitivity (ETS) setting during noninvasive pressure support ventilation (PSV) under the different conditions of respiratory mechanics. Methods Bi-level pressure ventilator was connected to a lung model (Hans Rudolph Series1101 simulator). And its mechanics was set to normal, obstructive and restrictive ventilation dysfunction. Tests were performed with pressure support levels of 10 (in normal condition, 1 cmH2O = 0.098 kPa) and 15 cmH2O, 5 cmH2O positive end-expiratory pressure (PEEP). The data including cycling delay time (Td), tidal volume (TV) and airflow were collected in the presence of air leaks (24-28 L/min). Results Significant performance on airflow was observed in various respiratory mechanics conditions. The peak inspiratory flow (PIF) and peak expiratory flow (PEF) were different, and the tidal volume, PEF and inspiratory time were increased after decreasing the ETS level. Premature cycling occurred frequently in normal and restrictive model. Delay cycling was found only when the ETS setting was at the lowest level (about 5% of PIF), at which Td were (15.20 ± 0.43) ms and (105.00 ± 15.82) ms. In obstructive model, PIF and PEF were significantly decreased, and delay cycling was always present. Td were increased after the ETS setting was changed from the most sensitive level to moderate level:(51.30 ± 12.63) ms vs. (162.40 ± 15.59) ms, as cycling-off criteria were reduced from (34.52 ± 3.36)% to (16.04 ± 2.58)% of PIF, and there were statistical differences (P<0.05). Severe delay cycling was found when the ETS level was at the lowest level. Conclusions There are significant differences in performances and cycling-off synchrony in various respiratory mechanics models during PSV. For Curative Flexo ST30 bi-level pressure ventilator, its flow cycling-off criteria range is about 5%-35%of PIF. The higher ETS level might be beneficial to improve patient-ventilator synchrony in patients with obstructive airway diseases, which could result in premature cycling in patients with restrictive disease.

Objective To investigate the prevalence of pulmonary acariasis among the employees working on traditional Chinese medicinal materials and observe the effect of treatment. Methods History inquiry, detection of mites in sputum, blood examination for eosinophils and specific antibodies, x-ray chest film were carried out for 327 workers involving in traditional Chinese medicinal materials. Mites were found in sputum in 121 persons who were then treated with metronidazole, twice a day with a daily dosage of 0.8g for seven days as a course of treatment. Two courses were conducted with an interval of 7-10 day. Prevalence and morbidity in different groups of occupation, age, and sex were analyzed. Results The overall infection rate of mites in sputum was 37.0% (121/327) with an average morbidity of 12.5% (41/327). Among the four types of worker investigated, the highest infection rate (51.8%), and morbidity (18.6%) were in those working in transfer warehouse; the second highest infection rate (40.7%) and morbidity (15.7%) were in employees in factory of Chinese traditional medicine. Both groups showed a significant difference with others(?2inf=11.36,P0.05). After treatment with metronidazole, 88.4% showed negative in sputum examination for mites and the efficacy of the treatment for pulmonary acariasis was 92.3%. Conclusions Employees engaged in traditional Chinese medicinal materials are one of the groups at the highest risk of pulmonary acariasis. Metronidazole is effective in treating the infection.

OBJECTIVE:
To investigate the clinical efficacy and advantages of Tianji orthopedic robot assisted cannulated screw internal fixation for femoral neck fracture.
METHODS:
The clinical data of 41 patients with femoral neck fracture who underwent internal fixation with cannulated screws from January 2019 to January 2022 were retrospectively analyzed. According to different surgical methods, they were divided into Tianji robot group and traditional cannulated screw fixation group (traditional operation group). Among them, there were 18 patients in Tianji robot group including 8 males and 10 females with age of (56.00±4.22) years old, Garden typeⅠ (4 cases), type Ⅱ (11 cases), type Ⅲ (2 cases), and type Ⅳ (1 case). There were 23 patients in the traditional operation group, including 10 males and 13 females, aged (54.87±4.81) years old;there were 5 cases of Garden typeⅠ, 14 cases of type Ⅱ, 3 cases of type Ⅲ and 1 case of type Ⅳ. The operation time, intraoperative blood loss, fluoroscopy times, guide needle placement times, operation costs and other indicators were observed and compared between two groups. Harris score was used to evaluate hip joint function 12 months after operation.
RESULTS:
The wounds of all patients healed in Grade A without complications. There were significant differences between two groups in terms of operation time, times of intraoperative fluoroscopy, times of guide needle placement, amount of intraoperative bleeding, and operation cost (P<0.05). All 41 patients were followed up for at least 12 months. The fractures of both groups were healed. There was no infection, screw loosening, fracture displacement and femoral head necrosis in Tianji robot group during follow-up;Screw loosening occurred in 2 patients in the traditional operation group during follow-up. At 12 months after operation, Harris hip joint function score of Tianji robot group was higher than that of traditional operation group in daily activity, lameness, joint activity score and total score (P<0.05).
CONCLUSION
Tianji robot assisted nail placement is a better method for the treatment of femoral neck fracture, which improves the surgical efficiency, is more accurate, has higher success rate of one-time nail placement, shorter operation time, less radiation, and has better hip joint function recovery after surgery.
