Oocytes are the germ cells of female animals, which determine the reproductive ability of female animals. A large amount of lipids are present in oocytes, which are found in lipid droplets mostly in the form of triglycerides. The size, color and distribution pattern of lipid droplets are associated with the developmental ability of oocytes. Triglycerides could be lipolyzed into fatty acids in oocytes. The fatty acid β-oxidation is an important energy source for the development of oocytes and early embryos. However, excessive lipid deposition would increase levels of reactive oxygen species (ROS), resulting in the dysfunction of mitochondria and endoplasmic reticulum, eventually impairing the subsequent oocyte development. By summarizing the positive and negative effects of lipids on oocyte development, this review shows the dual roles of lipids in oocyte development, and discusses the effects of lipids on oocyte development.

Objective To study the clinical diagnosis and treatment of malignant gastrointestinal stromal tumor. Methods To retrospectively analyze the clinical data of 28 cases with malignant gastrointestinal stromal tumors underweat surgical treatment . Results The malignant gastrointestinal stromal tumor in adults were more than 50 years old,71.4%(20/28) ,and common clinical symptoms were gastrointestinal bleeding,anemia,and pain. The lesion site: 19 cases of gastric bowel, 8 cases of small intestine, 1 case of colon, radical excision in 22 cases, local excision palliative resection in 5 cases, three cases were multi-visceral resection. Conclusion Malignant gastrointestinal stromal tumor could be diagnosed by the means of endoscopic imaging and clear,and preoperative diagnosis was difficult. Surgical resection was the pathology diagnosis and treatment of primary method,if necessary,to ensure multi-visceral resection of the tumor to prevent recurrence of thoroughness, had important significance.

AlM:To study the treatment effect of traditional Chinese medicine in the treatment of high myopia macular hemorrhage, using Chinese medicine etiology and pathogenesis, syndrome differentiation treatment, and provide the basis for the clinical treatment. METHODS: Eighty patients ( 135 eyes ) with high myopia macular hemorrhage were selected in the hospital from January 2012 to september 2014 as treatment group, and applied traditional Chinese medicine treatment. Forty-five patients (64 eyes) with the same period, as the control group, received routine western medicine treatment. After 1mo treatement, the treatment effect and vision improvement situation of two groups were observed, and after 6mo follow-up, the relapse was observed.RESULTS: The total effective rate of treatment group was 85. 19% (115/135), higher than the control group 78. 13% (50/64) (P<0. 05). The average corrected visual acuity of treatment group was 0. 48±0. 11, higher than the control group 0. 36 ± 0. 09, the difference was statistically significant (P<0. 05). The average diopter and macular bleeding scope of the treatment group were -9. 81±0. 85D and 0. 51 ± 0. 27PD, lower than the control group -10. 76 ± 0. 91D and 0. 78 ± 0. 23PD, the differences were statistically significant ( P < 0. 05 ). The eye ground hemorrhage absorption time of treatment group was 25. 34±2. 28d, less than the control group 29. 72 ± 2. 13d, the difference was statistically significant (P<0. 05). The bleeding again of the control group 7. 81% ( 5/64 ), higher than the treatment group was 5. 19% (7/135), the difference was statistically significant (P<0. 05).CONCLUSlON: Evidence-based treatment of traditional Chinese medicine for high myopia macular hemorrhage has good clinical effect, can shorten the treatment time, and is beneficial to the recovery of postoperative vision, worthy of clinical popularization and application.

OBJECTIVEThe study aimed to test if Paridis Rhizoma total saponins (PRTS) could induce apoptosis of human gastric cancer cell MKN-45.

METHODBased on the previous researches, PRTS was set by different concentrations to treat human gastric cancer cell for 12 h (5, 10, 20 mg x L(-1)). Fluorescent staining methods were adopted to observe apoptotic morphological changes of MKN-45. The apoptosis rates were analyzed by flow cytometry with Annexin V-FITC/PI staining. The enzymatic activities of caspase-3 and caspase-8 were measured by ELISA. The protein levels of Fas and FasL were detected by Western blotting.

RESULTUnder a fluorescence microscope, MKN-45 treated by PRTS was seen typical apoptotic morphological features. PRTS significantly increased the rate of apoptosis. Compared with the control group, there exsited significant differences in apoptosis rate of PRTS concentration of 20 mg x L(-1) (P < 0.01); besides, the enzymatic activities of caspase-3 and caspase-8 were promoted obviously after the effect of PRTS on MKN-45 cells for 12 h (P < 0.01). The protein levels of Fas and FasL in the MKN-45 were upgraded significantly.

CONCLUSIONPRTS can induce apoptosis of human gastric cancer cell MKN-45 , which is concerned with caspase-3 and caspase-8 and upgraded Fas and FasL.

This paper is aim to investigate the pharmacokinetics and absolute bioavailability of neoline in Beagle dogs, and provide a theoretical basis for further study. Ethyl acetate was used for liquid-liquid extracting after 10% ammonia alkalizing. The method of UPLC-Q-TOF-MS was established for the determination of neoline plasma concentrations. Beagle dogs were orally or intravenously administered with neoline for pharmacokinetic and absolute bioavailability study. Good linear relationship of neoline was found over the range of 0.1-4 mg x L(-1) (R2 = 0.9982) and 2-100 microg x L(-1) (R2 = 0.9945). Intra-and inter-day precision, expressed as the relativestandard (RSD) were less than 5.0%. Accuracy, expressed as the relative error (RE) was within 90.0%-115%. The recovery of neoline in dog plasma was more than 80%. After 6 mg x kg(-1) for ig and 1 mg x kg(-1) for iv administration of neoline, the main pharmacokinetic parameters were analyzed with Winnonlin software. t(1/2) were (313.88 +/- 63.18), (236.33 +/- 229.84) min, and AUC(0-infinity) were (58,027.40 +/- 14,132.69), (473,578.02 +/- 82,333.08) min x microg x L(-1) for ig and iv administration respectively. The absolute bioavail ability was (73.15 +/- 10.29) %. The method of UPLC-Q-TOF-MS described in the report was sensitive, reliable and specific, and suitable for pharmacokinetic study of neoline in Beagle dog. The high absolute bioavailability of neoline in dog suggested good absorption of neline which was worth of further investigation.
