AIM: To investigate the effect of PEDF on retinal neovascularization in mice. METHODS: 40 7-day-old C57BL/6J mice was exposed to 750mL/L oxygen for 5 days and then to normal situation to produce the murine model of oxygen-induced retinopathy(OIR). One eye of the mouse was regarded as experimental one and the other served as control. Eyes in experimental group received intravitreal injection of PEDF and eyes in control group received intravitreal injection of PBS at postnatal day 12. All mice were executed at postnatal day 17. The changes of retinal vessels of mice were observed by ADPase histochemical technique. The inhibitory effect of PEDF on retinal neovascularization was evaluated by counting the endotheliocyte nuclei of new vessels which extended from retina to vitreous in the tissue slice of HE staining. RESULTS: Neovascularization was reduced, retinal blood vessels distributed regularly and non-perfusion areas were not found in eyes of experimental group compared with control group. The number of endotheliocyte nuclei of new vessels extending from retina to vitreous was significantly less in the eyes of experimental group (10.18±1.74) than that in control group (38.89±2.98) (P<0.01). Retinal toxicity and inflammatory reactions were not found in tissue slice.CONCLUSION: PEDF inhibits retinal angiogenesis in OIR and the feasibility should be determined for use of PEDF in ocular angiogenesis treatment.

[Objective] To analyze the constituents of volatile oil from Nervilla fordii (NF) by gas chromatography-mass spectrometry (GM-MS). [Methods] Volatile oil was extracted from NF by steam distillation and the constituents of volatile oil were isolated and identified by GM-MS. The relative contents of the volatile constituents were calculated by ionic flow chromatographic area normalization method. [Results] Eighty-nine components were separated. Among them, fifty-three components were identified, accounting 91.82% of the total volatile oil. [Conclusion] The main constituents identified from NF were: 2-pentadecanone, 6,10,14-trimethyl (13.55%), 4-ethyl-trans-3-thiobicyclo [4,4,0] decane (6.54%), benzenesulfonamide, 4-methyl-N- (2-oxo-2 phenylethyl) (6.33%), phytol (6.32%),?-carinol (4.54%), ?-ionone (4.43%), caryophyllene oxide (4.13%). The amount of the above constituents accounts 45.84% of the total volatile oil.

OBJECTIVETo observe the effect of Yishen Zhongzi Pill (YZP) on the sperm motility of Shen-essence deficiency syndrome (SEDS) patients.

METHODSTotally 144 patients were randomly assigned to the treatment group (71 cases) and the control group (73 cases). Ten cases dropped out during the therapeutic course. A total of 134 patients completed this clinical study, 67 in each group. Patients in the treatment group took YZP (6 g each time, twice daily), while those in the control group took Wuzi Yanzong Pill (6 g each time, twice daily). The therapeutic course for all was one month. Changes of the sperm motility, clinical efficacy, and Chinese medical symptoms scores were observed between the two groups before and after treatment.

RESULTSCompared with before treatment in the same group, percentages of class a spermatozoa and class a + b spermatozoa were enhanced in the two groups after treatment (P <0. 01). Besides, they were higher in treatment group than in the control group (P <0. 05). The total effective rate of the treatment group was 77. 61 % (52/67 cases), while it was 58. 21 % (39/67 cases) in the control group. It was better in the treatment group than in the control group (Z= -2. 914, P =0. 004). Compared with before treatment in the same group, scores for Chinese medical symptoms decreased in the two groups (P <0. 01). The difference of pre-post integrals was higher in the treatment group than in the control group (P <0. 01).

CONCLUSIONYZP showed favorable effect in treating asthenospermia patients with SEDS and could effectively elevate the motility of sperm.

BACKGROUND: Endogenous opioid peptide is an important medium and regulator that participate in many physical and pathologic processes of the body. Its relationship with fetal encephalopathy has attracted much attraction.OBJECTIVE: To evaluate the role of endogenous opioid peptides (EOP) in fetal distress.DESIGN: A case-control observatory study based on healthy pregnant women.SETTING: Wards of the Department of Obstetrics and Gynecology of Changzheng Hospital Affiliated to Second Military Medical University of Chinese PLA.PARTICIPANTS: Eighty-three healthy women who were hospitalised in Changzheng Hospital and Changhai Hospital affiliated to the Second Military Medical University of Chinese PLA and met the inclusion criteria. Among them, 40 were normal healthy pregnant women(the control group) and 43 were healthy pregnant women with fetal distress(the fetal distress group).METHODS: Radioimmunoassay was used to measure the levels of blood EOP(β-endorphin, dynorphin A1- 13 and leu-enkephalin) of the venous blood of the pregnant women in fetal distress group and the control group and the EOP level in the umbilical blood of the newborns. Also, blood gas analysis of the blood from the umbilical artery was conducted.MAIN OUTCOME MEASURES: The levels of EOP in the venous blood of two groups of pregnant women and the umbilical blood of newborns and the correlation of EOP level with fetal distress.RESULTS: The levels of the umbilical artery blood EOP(β-endorphin,dynorphin A1-13 and leu-enkephalin) in the fetal distress group[(453± 68 ) ng/L, (242 ± 33)ng/L, and(498 ± 68)ng/L respectively] were significantly higher than those in the control group[ (251 ± 39) ng/L, (103± 22 )ng / L and(322 ± 40 )ng / L respectively ( t = 2. 713,2. 762, P＜ 0.01; t = 2. 132, P ＜ 0.05 ) ]. The umbilical artery blood gas analysis;pH was (7.0 ± 0. 1 ) , PO2 was ( 1.7 ± 0.6) kPa, PCO2 was (8.9 ± 0. 7) kPa.The levels of β-endorphin were negatively correlated with pH and PO2 of the umbilical artery blood(r= -0.418 and -0.437, P ＜ 0.01), but they were positively correlated with PCO2( r = 0. 442, P ＜ 0. 05) . The level of dynorphin A1-13 was negatively correlated with pH and PO2( r = -0. 337,-0.383, P ＜ 0.05), but it was positively correlated with PCO2(r= 0. 346, P ＜ 0. 05). There was no significant difference among the three kinds of blood EOP of the two groups( P ＞ 0.05).CONCLUSION: EOP participates in the pathological progress of the fetal distress and was closely correlated with the occurrence and development of the fetal distress. This finding has a reference value for early rehabilitation and intervention after the fetal was born that can be tested quantitatively.
