As a multifunctional cytokine,transforming growth factor-?(TGF-?) has many biological effects. It controls the extracellular matrix synthesis in trabecular meshwork cells and enhances the contractility of trabecular cells,which may increase the resistance of aqueous outflow. It can also promote the formation of the bleb scarring after filtration surgery. TGF-? is likely to play an important role in the pathogenesis and mechanism of primary open-angle glaucoma (POAG). The inhibitions of TGF-? may be used as an auxiliary agent for inhibiting the formation of the bleb scarring after filtration surgery.

Percheron artery infarct (PAI) is uncommon clinically.One case had an acute onset of coma,impaired left limb activities,verbal incoherence,drinking cough and vertical gaze palsy after regaining consciousness.Magnetic resonance imaging (MRI) showed symmetrical high signal intensity on diffusion-weighted imaging (DWI) in bilateral paramedian thalami and a distinct pattern of V-shaped midbrain hyperintensity on DWI.Magnetic resonance angiography (MRA) showed left-sided embryonal posterior cerebral artery (PCA) from ipsilateral internal carotid artery (ICA).Systemic treatment yielded a poor prognosis.

Objective To observe the clinical efficacy of synergism of TCM medicinal oxygen therapy in treating acute cerebral infarction.Methods Eighty cases were randomly divided into treatment group and control group, 40 cases in each group, and 1 case was lost in treatment group. Based on routine treatment, the control group was treated with low flow oxygen inhalation only, while the treatment group was treated with TCM medicinal oxygen therapy. The course of treatment was 2 weeks. The two groups were scored with National Institutes of Health Stroke Scale (NIHSS) and Stroke Symptom Scale of TCM (SSTCM) before and after the course to evaluate the therapeutic effect. Results The scores of NIHSS and SSTCM in both groups after the treatment were with statistical significance (P<0.05). There was no statistical difference in the scores of NIHSS between two groups after the treatment (P=0.10). There were statistical difference in the scores of SSTCM between two groups after the treatment (P<0.05). The clinically curative effect rate in treatment group was76.9% (30/39), which was superior to that of 60.0% (24/40) in the control group, with statistical significance (P=0.27).Conclusion TCM medicinal oxygen therapy can improve the neurological deficit and enhance the efficacy.

This paper discusses the problems, clinical application and limitations of argon-helium cryosurgical scalpel and liquid nitrogen cryosurgical scalpel. The feasibility of self-absorption liquid-CO2 cryosurgical scalpel is analyzed. The result shows that self-absorption liquid-CO2 cryosurgical scalpel can be applied to cryosurgery.

Objective To investigate the effects of group teaching in rehabilitation nursing. Methods 55 nursing students were dividedinto control group and experiment group. The control group received traditional teaching and the experiment group received group teaching.Questionnaire and examination performance were used to evaluate the effects of group teaching in the teaching of rehabilitation nursing. ResultsThe scores were significantly higher in the experiment group than in the control group (P<0.01). The questionnaire showed that groupteaching can stimulate their interest and intrinsic motivation for learning, enhance their understanding and application of knowledge, cultivatetheir self-learning ability, analysis and problem-solving abilities, interpersonal communication skills and spirit of collaboration. At thesame time, the implementation of group teaching helps both teaching and learning. Conclusion Group teaching can improve the teaching effectivenessof rehabilitation nursing.

ObjectiveTo investigate the effects of 5(S),6(R),7-trihydroxyheptanoic acid methyl ester (BML-111) on pregnant mice with fetal growth restriction(FGR) induced by antenatal dexamethasone and its probable mechanism. MethodsThe mice were mated overnight,with day 1 of pregnancy designated as the day on which spermatozoa were presented in a vaginal smear.The pregnant mice were then randomly divided into control group,dexamethasone group and BML-111 group.From 9 to 14 days of pregnancy,pregnant ICR mice of control,dexamethasone and BML-111 group were treated separately with saline,dexamethasone(5 mg/kg) and dexamethasone at 8:00 am,and two hours later they were treated separately again with 1 mg/kg saline,saline and BML-111.On the day 18 of gestation,they were sacrificed after blood were collected from their eyeballs.The serum lipoxin A4 was measured with enzyme-linked immunosorbent assay. Fetuses were delivered by cesarean section; the placenta and uterus were immediately removed and frozen.Gene expressions of 11β-hydroxysteroid dehydrogenase 2 ( 11β-HSD2 ),interleukin-1β (IL-1β) in placenta and lipoxin A4 receptor-formyl peptide receptor 3 (FPR3)in uterine were detected by reverse transcriptionpolymerase chain reaction and compared with analysis of variance.The 11β-HSD2 protein in mice placenta was detected by immunohistochemistry. ResultsThe mean fetal weight of dexamethasone group was (0.823±0.054) g,lower than that of the control group and BML-111 group [(1.103±0.218) g and (0.992 ± 0.207) g] (t =- 4.108 and - 2.890,P ＜ 0.05 respectively).Protein expression of 11β-HSD2 in dexamethasone group (0.030±0.019) was weaker than that in control group (0.058±0.015,t=-3.107,P＜0.05) or in BML-111 group (0.049±0.026,t=-2.211,P＜0.05).The expression of 11β-HSD2 mRNA in dexamethasone group (0.457±0.062) was lower than that in control group (0.943±0.057,t=-9.418,P＜0.05) or in BML-111 group (0.698±0.071,t=-4.617,P＜0.05).Expression of IL-1β mRNA in dexamethasone group (0.543±0.103)was less than that in control group (0.710± 0.085,t=-3.736,P＜0.05) but more than that in BML-111 group (0.229 ±0.031,t=7.025,P＜0.05). The expression of FPR3 mRNA in dexamethasone group (0.323 ± 0.019) was less than that in control group (0.857 ± 0.057,t =-14.630,P＜0.05) or in BML-111 group (0.499 ±0.050,t=-4.822,P＜0.05).The serum concentration of lipoxin A4 in dexamethasone group was lower than that in control group [(64.463±22.144) pg/ml vs (101.610±24.916) pg/ml,t=3.152,P＜0.05].ConclusionsBML-111 regulate the expression of 11β-HSD2 and then protect against FGR resulted from too much prenatal application of dexamethasone.

Six years' English teaching in department of obstetrics and gynecology in Wenzhou Medical College were reviewed. Language and cultural differences are the main reasons hindering teaching quality. Rational use of a variety of teachers,preparing for lessons adequately,adoption of English image data,supplying and revising English teaching materials,using network auxiliary teaching and forming ef-fective education mode are conducive to improving English teaching quality in department of obstetrics and gynecology for foreign students.

Objective To investigate the expression and clinical significance of lipoxin A4,leukotrienc C4,lipoxygenase-5 in peripheral blood of pregnant women with different types of severe preeclampsia.Methods Forty-five singleton pregnant women who accepted antenatal care and delivered in First Affiliated Hospital of Wenzhou Medical College were enrolled in this study from December 2010 to June 2011.All objects were divided into normal pregnancy group (n=20),early onset severe preeclampsia group (n=10) and late onset severe preeclampsia group (n=15).Enzymelinked immunosorbent assay was used to detect lipoxin A4 and leukotriene C4 levels in peripheral blood.The level of lipoxygenase-5 mRNA in white blood cells was detected by real time fluorescence quantitative reverse transcription-polymerase chain reaction.The differences of lipoxin A4,leukotriene C4 and lipoxygenase-5 mRNA among groups were compared by analysis of variance and LSD-t test;and correlations among their expressions were analyzed by linear regression.Results Lipoxin A4 level in early and late onset severe preeclampsia group was (355.3±116.0) pg/ml and (389.7±117.5) pg/ml,which were both significantly lower than that in normal pregnancy group [(555.0±139.8) pg/ml] (t=-4.03 and-3.77,P＜0.05 respectively).The leukotriene C4 level in early and lateonset severe preeclampsia and normal pregnaney group was (591.3±185.5) pg/ml,(510.3±197.1) pg/ml and (496.9 ± 158.8) pg/ml,no statistical difference were found (F=0.889,P＞0.05) ; neither did the expression of lipoxygenase 5 mRNA,which was 4.2± 1.9 in normal pregnancy group,4.8 ± 2.0 in early onset severe preeclampsia group and 4.4 ± 1.2 in late onset severe preeclampsia group (F=0.311,P＞0.05).There was no correlation among the levels of lipoxin A4,leukotriene C4 and lipoxygenase-5 mRNA in each group (P ＞ 0.05).Conclusions Early and remarkable decreasing of lipoxin A4 level might contribute to the development of early onset severe preeclampsia.
