Objective To explore the therapeutic effect of focused ultrasound(FU)on chronic cervicitis unitarily and its influential factors.Methods Three hundred and thirteen patients of chronic cervicitis were treated with the device of CZF model focused ultrasound.The therapeutic effects in 300 cases with complete records,as well as the relationship between the diameter of cervical erosion and the exposure time to FU were analyzed.Results The effective rates of FU in treatment of chronic cervicitis unitarily were 100.0%(53/53),95.2%(120/126)and 91.7%(111/121),respectively,for mild,moderate and severe cases.The overall effective rate was 94.7%(284/300).With other parameters of FU unchanged,the exposure time to FU showed an exponential relationship with the diameter of erosion,and the regression equation was D=31.71e~(0.4808t)(R~2=0.9966).Conclusions The controllability and achievement ratio of FU to treat cervical erosion could be enhanced when exposure time and manners were fully considered based on the diameter and type of cervical erosion.A satisfactory therapeutic efficacy could be achieved with FU to treat cervical erosion unitarily.

AIM To evaluate the anti-angiogenesis action of Bevacizumab on corneal neovascularization(CNV) in rats induced by alkali burns.·METHODS: 20 Health Wistar rats, aging from 6 to 8 weeks and weighting from 170g to 190g from 170g to 190g were prepared for CNV animal models. Both corneas of each animal in experimental were cauterized with alkali, then all rats were randomly divided into four groups (each group have 5 rats and 10 corneas), the both corneas of each rats were received subconjunctival Bevacizumab in different dosage (group 2, 0.5rag; group 3, 1.0mg; group 4, 2.0mg)and the group 1 received carrier solution. The occurrence and development ofCNVwereobservedbyslit-lamp microscope, and length and area of CNV were calculated. All rats were followeded up 16 days after alkali burns. The 40 corneas were taken for histopathological examination. Vascular endothelial growth factor (VEGF) were detected in all rat corneas by immunohistochemistry method. ·RESULTS: In the bevacizumabotreated eyes, the vascular area was lower than in the control eyes. The treated group was statistical differences compared with the control group; when vascular area were compared between the treated groups, no statistical differences were observed. The histopathological findings showed that the inflammation cells and the neovascularity in each treated group were significantly fewer than that in the control group. The expression of VEGF markedly increased in CNV control group compared with bevacizumab-injected group. ·CONCLUSION: Subconjunctival application of a certain concentrations Bevacizumab could inhibit angiogenesis in rats corneas induced by alkali burns.

Objective To study the distribution of IL-10 and TNF gene polymorphisms in patients with gastroduodenal diseases in Hubei Han ethnic and their association with Helicobacter pylori (Hp) infection. Methods Six hundred and five patients with gastroduedenal diseases (196 chronic gastritis, 189 gastroduodenal ulcer and 220 gastric cancer) as well as 624 healthy controls were genotyped with PCR-RFLP method for IL-10-1082,-819,-592 and TNFα-308, lymphotoxin-α (LTα) Nco Ⅰ and AspH Ⅰ gene polymorphisms. Hp infection status was determined with ELLS& Results (1) There was significant difference of IL-10-1082 AG + GG genotype among the gastric cancer group with the non-malignant gastric diseases groups and healthy control group (P <0. 05). There was no significant difference of IL-10-592 and -819 gene polymorphisms among gastric cancer patients,non-malignant gastric disease patients and healthy controls (P>0. 05). The genotype frequencies of IL-10-819 were the same as those of IL-10-592. (2) Frequency of IL-10-1082 AG + GG genotype in gastric cancer patients with positive Hp was significantly higher than that in the other three groups (P < 0. 05). (3) Frequency of LTα Nco I AG genotype in gastric cancer patients with Hp infection was signiilcandy higher than that in Hp positive healthy controls (P < 0. 05). There were no other associations between TNFα-308, LTα Nco Ⅰ and AspH Ⅰ gene polymorphisms and Hp infection in gastroduodenal diseases. Conclusions (1) Allele AG + GG of IL-10-1082 was associated with gastric cancer in Han nationality of Hubei province. (2) IL-10-1082 AG + GG,LTct Nco ⅠAG heterozygous genotype may be associated with Hp infection in patients with gastric cancer in Han nationality of Hubei province.

Objective To investigate the effect of recruitment maneuver (RM) on acute respiratory distress syndrome (ARDS).Methods A total of 7 patients with early ARDS were involved in this investigate with pressure-control ventilation of FiO2 =1.Hemodynamics and extravascular lung water index (EVLWI) were monitored.After airway preparation,the ventilation parameters were adjusted to inspiration pressure (Pi) =24 cm H2O,positive end-expiratory pressure (PEEP) =10 cm H2O,frequency (f) =50,inspiration/expiration (I/E) =5/1.Up regulated PEEP to 24 cm H2O and Pi to 45 cm H2O for 3 respiration cycles.Then down regulated Pi to 30 cm H2O and had the artery blood gas analysis immediately.If PaO2 ＜ 450 mm Hg,Pi was increased 5 cm H2O above the last one,until PaO2 ＞ 450 mm Hg,which was considered RM success.Then PEEP was decreased 2 cm H2O and repeated the cycle as formers until PaO2 ＜350 mm Hg.The optimal PEEP was 2cm H2O above that.Maintained this airway pressure at least for 4 hours.Artery blood gas and hemodynamics of pre-and post-RM were monitored.The RM would be stopped by any unstable hemodynamic.Results In 6 of 7 patients,PaO2 and PEEP were higher than the baseline (P ＜ 0.01) after 4 hours of RM ; EVLWI decreased (P ＜ 0.01).RM was stopped in 1 patient,because of the unstable hemodynamic.None of the 7 patients got RM complications ; meanwhile,6 patients were cured.Conclusions Applying RM on ARDS is safe and effective.

BackgroundMonocyte chemotactic protein-1 (MCP-1)plays an important role in the tumor,inflammation,diabetic retinopathy and other neovascular disease,but the expression and the role of MCP-1 in the oxygen induced retinopathy(OIR) model have rarely been reported. Objective This study was to investigate the expression of MCP-1 in the retina development of newborn mouse and in mouse models with OIR.Methods C57BL/6J newborn mice were divided into two groups and 60 mice in each group.Mice in OIR group were exposed to 75％ oxygen for 5 days and then to room air.All mice in normal control group exposed to room air only.Ten mice in each group were randomly chosen and sacrificed at postnatal 5,7,12,14,17,21 days.The expression of MCP-1 in mouse retina was detected with the method of immunohistoehemistry and reverse transcription polymerase chain reaction(RT-PCR).Results MCP-1 positive cells were seen in normal mouse retina.Up-regulation of MCP-1 positive cells was detected both in 12 days in normal control group and in 14 days in OIR group.MCP-1 mRNA was detected in mouse retina at 5 days,and a transient up-regulation of MCP-1 mRNA was observed in 12 days in normal control group.MCP-1 mRNA in OIR group significantly increased in 14 days in comparison with the normal control group( P =0.028,P =0.001 ). Conclusions Expression of MCP-1 is detectable in whole retinal development procession of mice.A transient up-regulation of MCP-1 expression is detected in the critical period of retinal vascular development in mice models with OIR,which is closely related to the retinal vascular development and progression of retinal new vessels.
