Objective To investigate the effect of microbubble(Sono Vue) destruction with ultrasound on wound healing in rats. Methods Total 96 SD rats were accepted one rounded whole-layer skin incision on back each other and randomly divided into four groups:microbubble destruction with ultrasound(US + MB),microbubble(MB), ultrasound(US) and control group. Rats in US + MB group were injected with 0.5 ml microbubble contrast agent via tail vein,and then ultrasound irradiated for 3 minutes immediately. MB group were injected with 0.5 ml microbubble contrast agent. US group were injected with 0.5 ml physiological saline,and then ultrasound irradiated for 3 minutes immediately under the same condition. Control group were injected with 0.5 ml physiological saline. Feed each rat in single cage. On day 1,3,5,7,14 and 21 after wound creation,the excised wound tissues were analyzed by histology and VEGF expression in wounds by immunohistochemistry. Results HE staining: On day 7, wounds of US + MB group displayed the most accumulation of granulation tissue and all new capillaries were perpendicular to the wound surface, but the new capillaries of other 3 groups were disordered. Immunohistochemical examination of VEGF expression:the peak expression appeared on day 3 in US + MB group, other 3 groups were on day 5 to day 7.Conclusions US + MB treatment could improve the quality of wound healing and granulation tissues were maturated earlier than MB, US treatment and control group, which could accelerate wound healing. High temperature,high pressure and some kind of chemistry effecs induced by microbubble destruction with ultrasound can stimulate the secretion of endogenous VEGF, which may be the mechanism of promoting angiogenesis and wound healing.

Objective To investigate the effect of hyperbaric oxygen(HBO)on p38 MAPK signal pathway in neuropathic pain,and explore its mechanism. Methods The experiment was divided into two parts with thirty SD rats in each part. Each part was then randomly divided into 3 groups:sham operation group(S group),chronic constriction group(CCI group)and hyperbaric oxygen group(HBO group),with 10 rats in each group. Part one:Pain?related behavior were detected on 3 day,7 day,14 day,28 day after operation. Phosphorylative p38 was detected by Western blot method and the P2X4 receptor was detected by immunohistochemistry method on the 28th day. Part two:All the rats were treated with SB203580. Pain?related behavior were detected on 3 day,7 day,14 day,28 day after operation. P2X4 receptor was detected by immunohistochem?istry method on the 28th day. Results CCI and HBO groups were significantly lower than S group in pain?related behaviors(P<0.05). CCI group was significantly lower than that in HBO group(P<0.05). The content of phosphorylative p38 and P2X4 receptor in CCI and HBO group were increased(P<0.05),and the expression of phosphorylative p38 and P2X4 in CCI group was significantly increased than that in HBO group (P<0.05). When p38 MAPK was inhibited,pain?related behavior in HBO and CCI group increased significantly than the pain?related behavior of HBO and CCI group in Part 1(P<0.05). But the difference between group CCI and HBO was not significant(P>0.05). Though the expression of P2X4 receptor in CCI group and HBO group was significantly higher than that in S group(P<0.05),the difference between group CCI and HBO was not significant(P>0.05). Conclusion Hyperbaric oxygen therapy can affect the expression of p38 MAPK through P2X4 receptor in rats of neuropathic pain.

Objective To investigate whether hyperbaric oxygen(HBO)affected neuropathic pain through autophagy and verify the HBO effect. Methods A total of 60 male SD rats were selected for the study and randomly divided into 4 groups:control group(C group),sham operation group (S group),chronic constriction group(CCI group)and hyperbaric oxygen group(HBO group). LC3Ⅱand P62 were determined by Western blot method and the autophagy was detected by electron microscopy on the 7th day. Results CCI and HBO groups were significantly higher than C and S group in Western blot(P<0.05). There was no difference between group C and group S(P>0.05). The expression of LC3Ⅱin HBO group was significantly higher than that in CCI group(P<0.05). And the expression of P62 in CCI group was significantly higher than that in HBO group(P<0.05). The autophagy in CCI and HBO group were significantly increased comparing to the C and S groups(P<0.05). However,the difference be?tween group C and S was not significant(P>0.05). Conclusion Hyperbaric oxygen therapy can induce autophagy for anti?neuropathic pain.

Objective To explore the relationship between the serum level of leptin,growth hormone(GH),insulin like growth factor-1(IGF-1),insulin like growth factor binding protein-3(IGFBP-3)and those modulatine effects on fetal growth.Methods One hundred and thirty-five cases of newborns were divided into 4 groups according to the relationship between born weight and gestational age.Group A:premature infants small for gestational age(SGA),n=30.Group B:premature infants appropriate for gestational age(AGA),n=36.Group C:mature infants small for gestational age,n=32.Group D:mature infants appropriate for gestational age,n=37.All infants were measured se-rum leptin,GH,IGF-1 and IGFBP-3 level with radiommunosassay(RIA).Results There were significant difference in the levels of leptin,GH,IGF-1,IGFBP-3 as group C0.05).There were positive correlation between levels of leptin,IGF-1 and IGFBP-3 in group A,B and C,while,there was positive correlation between only level of IGF-1 in group D.Conclusions Leptin,IGF-1 and IGFBP-3 may play an important role in the fetal growth regulation of premature infants and IUGR infants.IGF-1 also regulate intrauterine growth of group D.Another side,in group D,Leptin,GH,IGF-1 and IGFBP-3 don't regulate fetal growth.

Glaucoma is the first leading cause of irreversible blindness and the second leading cause of blindness worldwide. Numerous studies have shown that elevated intraocular pressure ( IOP ) is one of the major risk factors for the development and progression of glaucomatous optic nerve damage. However, there have been 50% of primary open-angle glaucoma ( POAG ) patients with typical glaucomatous optic neuropathy in whom the IOP measurements have always been in the normal range, and some patients develop typical glaucomatous optic neuropathy with the well controlled IOP. These phenomena cannot be explained by the theory of high intraocular pressure. The pathogenesis of glaucomatous optic nerve damage in these patients with normal IOP needs to be further discussed. Numerous studies at home and abroad have shown that: 1. the surrounding anatomy of the optic nerve including the IOP, the anatomy and biomechanics of the lamina cribrosa and retrobulbar orbital cerebrospinal fluid pressure may be of importance for the pathogenesis of the POAG;2. patients with normal tension glaucoma had significantly lower cerebrospinal fluid pressure and a higher trans - lamina cribrosa pressure difference compared with normal subjects; 3. patients with ocular hypertension had significantly higher cerebrospinal fluid pressure, however, there is no difference in trans -lamina cribrosa pressure compared with normal subjects. Based on the above research, now we make a review about the research advance of the relation between intracranial pressure and glaucoma optic nerve damage and the available measurements about noninvasive intracranial pressure in clinical in this paper.

Objective To evaluate the diagnostic efficacy of MR urography(MRU) in the diagnosis of urinary diseases. Methods MR urography was performed in 58 patients with urologic diseases,inclu- ding :renal tuberculosis(6),various congenital anomalies of urinary tract(27),renal pelvis carcinoma(2), ureteral carcinoma (10),ureteral polyp(2),ureteral calculi(8) and iatrogenic ureteral stricture(3). Results MR urography provided high-resolution images of the kidneys and urinary tract in all patients.The characteristics of renal tuberculosis,urinary tract dilation and the various anatomic anomalies were depicted well.MR urography was successful in localizing the level of obstruction in all of the 58 patients(100%),although MR urography alone could not reliably determine the cause of obstruction in some cases. Conclusions In diagnosing urinary diseases,MR urography has its advantages and limitations.It should be used appropriately in diagnosing urinary diseases.
