OBJECTIVE To clone the MSI-78 gene for the purpose of providing evidence for further studies in prokaryotic expression and activities of antimicrobial peptides. METHODS According to the amino acid sequences of MSI-78,the MSI-78 gene was designed favorable for the Escherichia coli codons. After EcoRⅠand PstⅠ disgestion,cohesive ends were added to both ends respectively and the MSI-78 gene was synthesized by chemical methods. Then,the MSI-78 gene was ligated with pUC-18,transformed into the E. coli DH5?. Through filtration of ? complementary screening,the positive recombinant was finally identified by enzyme digestion of ECORⅠand ECORⅠ/PstⅠ and by PCR. RESULTS The MSI-78 gene was ligated with pUC-18 and transformed into the E. coli DH5?. As a result,MSI-78 gene was cloned in E. coli DH5? successfully. CONCLUSIONS The cloning of the MSI-78 gene provides evidence for further studies of its prokaryotic expression and activities of antimicrobial peptides.

Objective To investigate the effects of breviscapine on the renal structure, function and PKC-?mRNA and its protein expression in brain-dead BA-Ma mini pigs. Methods Fifteen BA-Ma mini pigs were randomly divided into 3 groups: brain-dead group (group A), breviscapine pretreatment group (group B), and control group (group C), 5 pigs in each group. The brain-dead models were established by increasing intracranial pressure in a modified, slow and intermittent way. At 3, 6, 12, 18 and 24 h after the initial brain death, serum BUN, Cr, TNF-?, IL-1?, and IL-6 were determined. At 3, 6, 12, and 24 h, the changes of renal tissues were observed by HE staining, and the expression of PKC-?mRNA and protein was detected by RT-PCR and immnohistochemistry respectively. The ultrastructural changes of hepatic cells were observed under electron microscopy. Results (1) At 3rd h after the initial brain death, IL-1?, IL-6, and TNF-?in group A and group B began to increase. Serum BUN and Cr in group A and group B began to increase at 12 th after brain death and were higher at each time point (P

The Montreux definition established in 2017 made it clear that the neonates can not be excluded from the diagnosis of acute respiratory distress syndrome (ARDS), which supported the urge of emphasizing the specificity and importance of neonatal ARDS (nARDS) in the past ten years in China. Neonatal idiopathic respiratory distress syndrome is caused primarily by insufficient pulmonary surfactant system, which pathologically and clinically presented as typical respiratory distress syndrome. While the causes of nARDS often coexisted with underlying conditions, and its pathological and clinical features are a superposition of both respiratory distress syndrome and underlying conditions. Therefore, superimposition is the key to understanding the etiology, pathology, diagnosis, and treatment of nARDS, which is crucial for optimizing the clinical practice of nARDS.

BACKGROUND: The cel density is one of the factors involved in the state of cel differentiation, and the effect of cel density on transforming growth factor-β1-induced epithelial-mesenchymal transition of HaCaT cells is stil unclear. OBJECTIVE: To observe the effect of cel density on transforming growth factor-β1-induced epithelial-mesenchymal transition of HaCaT cells. METHODS: HaCaT cells was seeded in 6-wel plates at low density of 103/cm2 and high density of 105/cm2 then treated by 2 μg/L transforming growth factor-β1 for 48 hours, thereafter observed the changes in cel morphology. The transcription levels of epithelial cadherin, tight junction protein-1, vimentin, neuronal-cadherin were detected by real-time PCR, and expression levels of epithelial cadherin and vimentin were detected by Western blot. RESULTS AND CONCLUSION: Cel gap of HaCaT cells grew larger after treated with transforming growth factor-β1 for 48 hours, and cel morphology was long spindle rather than polygonal in low-density group, while in high-density group without obvious morphological changes. The real-time PCR showed that the transcriptions of epithelial cel marker epithelial cadherin and tight junction protein-1 were suppressed when compared with the control group (P < 0.05), and the decreasing deree in the high-density group was higher than that in the low-density group (P <0.05), mesenchymal cel marker neuronal-cadherin and vimentin were upregulated in the high-density group and the low-density group when compared with the control group (P < 0.05), and there were no significant differences between high-density group and low-density group. Western blot results verified the changes of neuronal-cadherin and vimentin expression level. These results suggest that the high seeding density can inhibit transforming growth factor-β1-induced epithelial-mesenchymal transition of HaCaT cells.

AIM: To evaluate the clinical efficacy of surgery for spontaneous subconjunctival orbital fat prolapse via bulbar conjunctiva under topical anesthesia.
●METHODS: A total of 22 eyes of 11 patients received surgery for spontaneous subconjunctival orbital fat prolapse via bulbar conjunctiva under topical anesthesia were included. Objective and subjective duration of the operation, degree of cooperation during surgery, postoperative recovery, recurrence and complications were observed.

Objective To evaluate the protection effects of glycine on the brain dead donor liver. Methods 42 male Wistar rats were randomized into 3 groups of liver transplantation: brain dead donor (BDD) group (group B), glycine pretreatment group with BDD (group G), strychnine pretreatment group with BDD (group S). For groups B, G and S, the brain death model was established in the donor rats and then liver transplantation was performed utilizing microsurgical techniques. After establishment of brain death state, and during liver cold rinse of donors or liver reperfusion of the recipients, rats in group B were treated with glycine at a dose of 0.6 mmol, 25 ?mol and 25 ?mol in group G, and rats in group S were given the same dose of glycine and strychnine ( 1 000 ∶1), and rats in group B were not treated. Before the cold rinse, at 2 h and 6 h after the portal vein (PV) reperfusion, blood samples were taken from IHVC to determine the levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), tumor necrosis factor alpha (TNF ?) and hyaluronic acid (HA). At 6 h after PV reperfusion, graft samples were fixed for morphological observation and the apoptosis of hepatocytes was detected by using TUNEL method. Results At the time points before liver cold rinse or at 2 h and 6 h after PV reperfusion, serum levels of ALT, AST, TNF ?, HA and apoptosis index (AI) in groups B and S were significantly higher than those in group G ( P 0.05 ). Electron microscopy showed that Kupffer cells were activated and hepatic cells injured more obviously in groups B and S than in group G. Conclusion Glycine may alleviate the injury of the graft from the brain dead rats.

ive] To observe the effects of Shengjiang Capsule (SC) on gastric evacuation and to study its mechanism. [Methods] Eight-week-old SD rats were randomly allocated to five groups. Group A served as normal control, and Group B were treated with high dosage of SC, Group C with low dosage of SC, Group D with Zhike Baizhu Decotion and Group E with cisapride. After ten days of treatment, gas tric evacuation of rats was detected by isotope tracing method, erythrocyte-acetycholinesterase activity by micro-hydroxylamine method and plasma motilin (Mot) and somatostatin (SS) levels by radioimmunoas-say. [Results] Thirty-minute gastric evacuation rate was (51.44?.38)%, (40.82 + 7.24)% and (40.22?.16)% in Group B, Group C and Group D respectively, which was higher than that in Group A [ (33.18?.32)%]. Erythrocyte-acetycholinesterase activity, Mot and SS levels were (0.856?.128) umol/h, (124.26?5.94) ng/L and (39.42?.96) ng/L, and (0.726?.164 ) umol/h, (119.86 ?9.38) ng/L and (38.33 ?.64) ng/L in Group B and Group C respectively, which were higher than those in Group A [ (0.576 ?.150)/umol/h, (91.28 + 26.84) ng/L and (28.22 ?7.68)ng/L]. [Conclusion] SC can promote gastric evacuation, and its mechanism may be re lated to the increase of the cholinergic nerve function and plasma Mot and SS levels.
