Capillary bronchitis is a common respiratory infectious disease. In the early childhood,it is mainly caused by respiratory syncytial virus,which is closely related with later asthma. The pathogenesis is still not entirely clear. Recent studies have found that glutathione functions in keeping airway epithelial integrity,a-gainst lung injury and inflammation. This article summarizes the protective effect of glutathione in capillary bron-chitis.

Objective To explore the impact of lung-protective mechanical ventilation (low tidal volume and optimal positive end-expiratory pressure (PEEP) on cerebral perfusion pressure (CPP) and cerebral oxygen metabolism.Methods Forty patients with severe cerebral injury along with respiratory failure were randomly assigned into two groups:lung-protective ventilation group A and conventional ventilation group B.Group A was planned to prescribe tidal volume 6 ～ 8 mL/kg,initial FiO240％,PEEP gradually increasing from 2 cmH2O to matched with FiO2 elevation,but the FiO2 was kept at permissive lower level.Group B was formulated with tidal volume 8 ～ 12 mL/kg,PEEP stepwise increasing from 0 2 cmH2O to match with FiO2 elevation,but PEEP was kept at permissive lower pressure.The intracranial pressure (ICP),mean arterial pressure (MAP),CPP,arterial and jugular venous blood gas were monitored.Results PEEP (8.2±3.32 cmH2O),ICP (19.7 ±3.6 mmHg),PaCO2 (54±7.3 mmHg),jugular venous carbon dioxide partial pressure (PjV CO2,56.7 ± 9.6 mmHg) in group A were higher than those (5.7±2.3 cmH2O,16.9±3.8 mmHg,41 ±5.2 mmHg,49.8 ±6.9 mmHg) in group B (P＜ 0.05 or P ＜ 0.01).VT,FiO2 in the group A were lower than those in the group B.There were no differences in PaO2/FiO2,jugular venous oxygen saturation (SjVO2),MAP,and CPP between two groups.PaCO2 were significantly correlated with CPP (r =0.368,P =0.019) while there was no correlation with ICP,PaO2,SjVO2,PjVCO2 (all P ＞0.05).CPP (69.7 ± 12.3 mmHg) was higher in case of PaCO2 (46 ～60mmHg) than those (61.5 ±9.1 mmHg) in case of PaCO2 (35 ～45 mmHg).There was correlation between PEEP and ICP (r =0.436,P =0.005).When PEEP was divided into three groups:≤52 cmH2O,6 ～ 102 cmH2O and ＞ 102 cmH2O,ICPs were different one another among three groups.When PEEP ＞ 102 cmH2O,it had a distinguished negative correlation with CPP (r =-0.395,P =0.017),while PEEP ≤ 102 cmH2O,CPP presented decreasing tendency.SjVO2 correlated with PaO2 (r =0.403,P =0.014) and PjVCO2 (r =-0.502,P =0.001) respectively.There were no significant relationships between SjVO2 and CPP,ICP,MAP,PEEP,respectively.Conclusions Lung-protective mechanical ventilation was relatively safer in patients with severe cerebral injury compared with conventional mechanical ventilation.Mild PaCO2 elevation (46 ～ 60 mmHg) combined with higher PEEP (＜ 102 cmH2O) did not decrease CPP.There was no difference in SjVO2 between the two modes of mechanical ventilation,suggesting no changes in cerebral metabolism occurred.

Objective To establish a radioresistant human cell line from esophageal squamous car-cinoma cells and detect the marker expression of cancer stem cells (CSCs). Methods A radioresistant hu-man esophageal squamous carcinoma cell line KYSE-150R was established by fractionated irradiation. Mor-phological changes from KYSE-150 to KYSE-150R were observed by phase- contrast microscopy. Karyotype analysis was performed by G-banding. The radiosensitivity of these two cell lines was assessed by colony for-marion assays. The cell cycle distribution was assayed by flow cytometry. CSCs markers of β-catenin and In-tegrin-β_1 were measured by Western Blot. Results The population doubling time of KYSE-150 and KYSE-150R were (23.62±0.23) hrand (25.90±0.55) hr, respectively (t =6.62,P=0.00). The numbers of chromosomes in KYSE-150R cells were increased and chromosome aberrations were observed. The SF_2, D_0, D_q and N values of KYSE-150R were all higher than those of KYSE-150. The ratio of D_0 values was 1.21. After irradiation, the number of S-phase cells of KYSE-150 increased from 45.35%±4.03% to 55.09%± 1.70% (t = -3.86,P=0.02) and G2/M phase cells decreased from 9.91%±3.83% to 1.15%±0.32% (t = 3.95, P = 0.02). However, no apparent change of cell cycle distribution for KYSE- 150R was observed. The expression levels of CSCs markers, β-catenin and Integrin-β_1 in KYSE-150R were about 2 times of those in KYSE-150. Conclusions The new cell line KYSE-150R is more radioresistant than its parental cell line KYSE-150. The CSCs in KYSE-150R is more than those in KYSE-150, which may suggest that CSCs is re-lated with the radioresistance.

This paper reports a woman diagnosed with citrullinemia type I (CTLNⅠ) in puerperium who was unfortunately died later. The 28-year-old patient (G1P1) delivered a live girl at 39 +2 gestational weeks and was transferred from a local hospital to Henan Provincial People's Hospital on January 11, 2020, due to "a 3-day paroxysmal confusion accompanied by dizziness 4 days after delivery". Intermittent confusion, elevated blood ammonia, and citrulline concentration, and encephaledema were presented 10 h after delivery, and the patient eventually died of cerebral hernia on the day of self-discharge. Two pathogenic mutations of the ASS1 gene were found by genetic testing, including c.422t>G (p.val141gl; HET) and c.431c>G (p.pro144arg; HET) and confirmed the diagnosis of CTLNⅠ. CTLNⅠ is a life-threatening disease that could be easily overlooked and misdiagnosed and was difficult to treat. It most often occurs in newborns and infants, whilst it is rare during pregnancy and postpartum. The possibility of this disease should be considered in patients with neurological system symptoms and elevated blood ammonia during pregnancy or puerperium.

BACKGROUND: It is indicated in researches of recent years that both astragalus and angelica act on anti-free radical and protect renal injury due to ischemia / reperfusion.OBJECTIVE: To observe the protection and its mechanism of astragalus and angelica injections on adenosine triphosphate-ase (ATPase) in renal injury due to ischemia/reperfusion.DESIGN: The observing controlled experiment based on experimental animals .SETTING: Physiological teaching & research room and teaching & research room of renal functional protection in a medical college. MATERIALS: The experiment was performed in Physiological Experimental Room of Luzhou Medical College from January 2001 to March 2001. Totally 33 Japanese big-ear white healthy adult rabbits of either sex were employed,provided by Experimental Animal Center of Luzhou Medical College, in the mass of(1.63 + 0. 22) kg. According to random number table, they were divided in sham-operation control(8 rabbits), simple ischemia/reperfusion group (8 rabbits), astragalus injection + ischemia/reperfusion group (astragalus group) (8 rabbits) and angelica injection + ischemia/reperfusion group(angelica group) (9 rabbits).METHODS: One day before operation, on the day of operation and 1 day after operation, successively, intravenous medical injections (astragalus 1.25 g/kg,angelica 12.5 g/kg) were administrated in astragalus and angelica groups everyday respectively, and injection with physiological saline 5 mL/kg was applied in the control and simple ischemia/reperfusion group. In 48 hours reperfusion after 1 hour ischemia in kidney, blood sample was collected from inferior vena cava. The upper tissue of the right kidney was collected and fixed by placed in 30 mL/L glutaraldehyde and the lower tissue was prepared into homogenate. Ultrastructure of renal tissue was examined with electron microscope; serum creatinine level and ATPase activity in renal tissue were assayed.MAIN OUTCOME MEASURES: Ultrastructure of renal tissue, serum creatinine level and ATPase activity in renal tissue.RESULTS: In simple ischemia/reperfusion group, renal tissue was degenerated significantly, and the disorders in astragalus and angelica groups were reduced markedly compared with simple ischemia/reperfusion group. Serum creatinine level in simple ischemia/reperfusion group was higher remarkably than the sham-operation control ( P ＜ 0. 05 ), and that in astragalus and angelica groups was reduced than simple ischemia/reperfusion group (P ＜ 0. 05) . In simple ischemia/reperfusion group, the levels of Mg2+-ATPaes, Na+-K+-ATPase and Ca2+-ATPase were(0. 155 ±0. 020),(0.179±0.018), (0.150±0.022) nkat/g respectively, which was markedly reduced compared with sham-operation control [ (0. 174 + 0. 012),(0. 198 + 0. 012), (0. 181 + 0. 017) nkat/g], ( t = 2. 344, 2. 438, 3. 014,P ＜ 0.05 ). In astragalus and angelica groups, respectively, the activities of Mg2+-ATPaes, Na+-K+-ATPase and Ca2+-ATPase were(0. 172 ± 0. 023),(0. 196 ±0. 077), (0. 175 ±0. 016) and (0. 177 ±0. 015), (0. 200 ±0.011 )and (0. 181 ± 0. 025) nkat/g successively. Except that Mg2+-ATPaes activity in astragalus group was not different significantly from that in simple ischemia/reperfusion group, all the rest were higher than simple ischemia/reperfusion group(t =2. 372 -2. 786, P ＜0.05).CONCLUSION: Both astragalus and angelica inhibit the decrease of ATPase and improve the disturbed local blood-flow adjustment in kidney, which has provided experimental basis of astragalus and angelica on reducing renal injury induced by ischemia/reperfusion through protecting ATPase.
