Objective To evaluate the effect of penehyclidine hydrochloride on cell apoptosis during acute lung injury (ALI) induced by two-hit in rats.Methods Thirty male SPF Sprague-Dawley rats, aged 8 weeks, weighing 240-270 g, were randomly assigned into 3 groups (n =10 each) using a random number table: sham operation group (group Sham), ALI induced by blunt chest trauma and hemorrhagic shock group (group ALI), and penehyclidine hydrochloric group (group PHC).In ALI and PHC groups, the rats were subjected to the combination of chest trauma and hemorrhage (mean arterial pressure 35-40 mmHg mm Hg, lasting for 60 min) to establish a model of ALI.In group PHC, penehyclidine hydrochloric 2 mg/kg was injected intraperitoneally at 1 h before blunt chest trauma.At 8 h after successful establishment of the model, the rats were sacrificed, and lungs were removed for examination of the pathologic changes and for determination of Bax, Bcl-2 and caspase-3 expression (using Western blot), tumor necrosis factor-alpha (TNF-α) content (by enzyme-linked immunosorbent assay) , and cell apoptosis (by TUNEL).Apoptotic index was calculated.Results Compared with group Sham, the levels of Bax, caspase-3 and TNF-α and apoptotic index were significantly increased, and Bcl-2 expression was down-regulated in ALI and PHC groups.Compared with group ALI, the levels of Bax, caspase-3 and TNF-α and apoptotic index were significantly decreased, and Bcl-2 expression was up-regulated in group PHC.The pathologic changes of lungs were significantly reduced in group PHC than in group ALI.Conclusion Penehyclidine hydrochloride mitigates ALI induced by two-hit through inhibiting cell apoptosis in rats.

Objective To investigate the neuroprotective effect and possible mechanism of nicorandil in mice under deep hypothermic low flow (DHLF). Methods A total of 105 3-week-old male C57/BL-6 mice were randomly divided into 7 groups: sham operation, model, nicorandil (5, 10, and 20 mg/kg), nicorandil 20 mg/kg + LY294002, and LY294002 groups (n = 15 in each group). A DHLF model was induced. At 24 h after reperfusion, the brain tissues of mice were taken out for HE and TUNEL staining. The pathological changes of cerebral cortical neurons and apoptosis were observed. Western blot was used to detect the expression levels of the total Akt, phospho-Akt (p-Akt), Bcl-2, and Bax. Results HE pathological staining showed that cortical neuronal injury was reduced, the phenomena of cel membrane depression, nuclear condensation, concentrated dye, and the blurring of the nucleus were decreased significantly in nicorandil group. The morphology of neurons was basicaly restored to normal. TUNEL staining showed that the apoptosis index in various dose groups of nicorandil was decreased significantly compared with the model group (al P < 0. 05). Western blot analysis showed that the expression levels of p-Akt and Bcl-2 proteins increased significantly in various dose groups of nicorandil compared with the model group (al P < 0. 05), and the expression level of Bax protein was decreased significantly (al P < 0. 05 ). After adding the phosphatidylinositol 3-kinase (PI3K) specific inhibitor LY294002, there was no significant difference in neurons pathological injury in the cortex compared with the model group. There was no significant difference in the apoptosis index, and the expression levels of p-Akt, Bcl-2, and Bax compared with the model group. Conclusions Nicorandil has a certain neuroprotective effect in mice under DHLF. Its mechanism may be associated with the activation of PI3K/Akt signaling pathway, and then further regulation of the downstream protein Bcl-2 and Bax expression.

Objective To evaluate the relationship between inflammatory responses and autophagy in lung tissues after scald and nucleotide-binding oligomerization domain-containing protein 2 (NOD2) signaling pathway in septic rats.Methods Twenty SPF healthy male Sprague-Dawley rats,weighing 200-250 g,were divided into control group (group C,n=10) and sepsis after scald group (group SS,n=10) using a random number table.The rats were subjected to a third-degree scald burn covering 20％ of total body surface area (body surface was shaved and then exposed to 99-100 ℃ water for 12 s),and 24 h later muramyldipeptide 5 mg/kg was intravenously injected to induce sepsis.The rats were only exposed to 20 ℃ water,and 24 h later normal saline 1 ml was given instead in group C.At 6 h after muramyldipeptide injection in group SS and at 6 h after normal saline injection in group C,arterial blood samples were collected for determination of serum tumor necrosis factor-r and interleukin-6 concentrations by enzyme-linked immunosorbent assay.Then rats were sacrificed and lungs were removed tor measurement of activity of myeloperoxidase,NOD2 mRNA expression (using real-time polymerase chain reaction) and expression of receptor interacting protein 2,nuclear factor kappa Bp65 and microtubule-associated protein 1 light chain 3 Ⅰ (LC3 Ⅰ) and LC3 Ⅱ in lung tissues (by Western blot).The LC3 Ⅱ / Ⅰ ratio was calculated.Results Compared with group C,the expression of NOD2 mRNA,receptor interacting protein 2 and nuclear factor kappa Bp65 was significantly up-regulated,and the LC3 Ⅱ / Ⅰ ratio and serum tumor necrosis factor-α and interleukin-6 concentrations were increased in group SS (P＜0.05).Conclusion The mechanism underlying enhanced inflammatory responses and autophagy in lung tissues during sepsis after scald may be related to activation of NOD2 signaling pathway in rats.

Objective:To evaluate the efficacy and safety of comprehensive treatment for retinoblastoma (RB).Methods:A retrospective clinical study. From January to December in 2019, 157 cases (203 eyes) of RB who were diagnosed by the Department of Ophthalmology of Xinhua Hospital and received comprehensive treatment were included in this study. Of cases, 76 were male, and 81 were female; 111 were unilateral, and 46 were bilateral. The medium of age at diagnosis was 20.1 months. All patients received treatment for the first time. Patients with intraocular tumors were divided into A-E stages, extraocular stage and distant metastasis according to international intraocular RB classification standard. The median follow-up time was 37.4 months. Clinical features, treatment, prognosis and ocular complications of all cases were recorded.Results:Among 157 cases (203 eyes), 137 cases (180 eyes) were in intraocular stage; 6, 14, 10, 98, and 52 of eyes were in A-E stages, respectively. Twelve cases (12 eyes) were in extraocular stage; 8 cases (11 eyes) were in distant metastasis stag; 8 cases died due to distant metastasis; 149 cases (94.9%, 149/157) survived; 48 eyes were enucleated, 34 of which underwent initial enucleation, and 14 eyes underwent enucleation after eye-preserving treatment. The overall global salvage rate was 155 eyes (76.4%,155/203), and that after eye-preserving treatment was 91.7% (155/169). Severer eye for bilateral cases was taken into account for statistic; 120 cases (120 eyes) received initial eye-preserving treatment. Among them, 36 and 84 eyes underwent initial intravenous chemotherapy (IVC) and initial intra-arterial chemotherapy (IAC), respectively. The enucleation of the two groups was 7(19.4%, 7/36), 7(8.3%, 7/84); 33 (91.7%, 33/36) and 33 (39.3%, 33/84) eyes received the second treatment, respectively. There was no significant difference in the rate of enucleation between the two treatments ( χ2=2.037, P=0.154). There was significant difference in the percentage of secondary treatment ( χ2=27.937, P<0.001). Fifty-four eyes (45.0%, 54/120) stabilized after initial treatment, and 66 eyes (55.0%, 66/120) underwent secondary treatments due to poor response or tumor recurrence. For 66 eyes receiving secondary treatments, enucleation, IAC, intravitreous chemotherapy (IVitC), IAC combined with IVitC, and laser and/or cryotherapy was performed in 6, 18, 12, 13, and 17 eyes, respectively. The number of eyes of enucleation among the IAC, IVitC, and IAC combined with IVitC group was 5 (27.8%, 5/18), 1 (9.3%, 1/12), and 2 (15.4%, 2/13) eyes, which was no significantly different ( χ2=2.001, P=0.368). Until the last follow-up, visual acuity outcomes were acquired in 148 eyes (72.9%, 148/203). Among them, 41, 53, 16 and 38 eyes had no light perception, light perception to finger counting, 20/400, and ≥20/200, respectively. In total, among 203 eyes, 121 eyes received IAC, of which 2, 4, and 1 eyes had optic disc atrophy, vitreous hemorrhage, and severe retinal-choroidal atrophy, respectively; 60 eyes received IVitC, of which one and one eye had vitreous hemorrhage and macular hemorrhagic necrosis, respectively. Conclusions:In this study, the overall survival rate was 94.9% after comprehensive treatment and the rate of global salvage after eye-preserving treatment was 91.7%. The comprehensive treatment of retinoblastoma had a relatively high efficacy and safety.
