  Objective To compare the clinical and laboratory results of three different controlled superovulation protocols in vitro fertilization and embryo transfer(IVF-ET), and from the actual situation of patients, provide a basis for clinicians to choose the best superovulation protocol.Methods Patients′ data were retrospectively analyzed who underwent IVF-ET for 1996 fresh cycles in our reproductive center from January 2016 to August 2019, and were divided into super long program group (471 cycles) and long program group (818 cycles), and antagonist program group (707 cycles) according to different hyperovulation programs. The differences were statistically analyzed in the general situation, clinical medication, timing of egg retrieval, trigger type and laboratory related data of the three groups of patients.Results BMI, bFSH, bLH and bE₂ of the antagonist program group were all higher than those of the other two groups, and compared with those of the long program group, P<0.05, while bT and bAFC in the antagonist program group were higher than those in the super long program group, P<0.05. The number of Gn days in the super long program group was higher than that in the other two groups, P<0.05. PhCGE₂ and hCGE₂ in the antagonist program group were significantly lower than those in the other two groups, P<0.05. HCGAFC in the antagonist program group was less than that in the other two groups, P<0.05. The amount of trigger HCG in the antagonist program group was less than that in the other two groups, P<0.05. The number of eggs in the long program group was higher than that in the super long program group, P<0.05. The number of high quality embryos and 2PN in the long program group was higher than that in the super long program group, P<0.05. HCG trigger type accounted for the highest proportion, and Gn trigger was not used in the super long program. There were many types of H/G double triggers in antagonist program. There was no significant difference intrigger type between the patients in the super long program group and the long program group. Trigger types were compared among patients in three groups of protocols, P<0.05.Conclusion Among the three ovulation induction programs, each has its own indications. According to the existing clinical data, the basic situation of the patient is analyzed to select the unique advantages of each ovulation induction program, the best ovulation induction program and the trigger type, to grasp the proper timing of egg retrieval, to get the right number of eggs as much as possible, and to cultivate a good embryo in order to make the most benefits for the patients.

  Objective To further explore the effect of obstructive sleep apnea hypopnea syndrome (OSAHS) on early neurologic deterioration (END) in patients with acute cerebral infarction through clinical prospective study.Methods Seventy-six OSAHS patients with acute cerebral infarction were selected, and 76 cases of acute cerebral infarction in the same period were selected as the control group. Age, disease history, blood glucose, blood lipid and blood pressure were measured and collected. All patients were examined by head and neck CT vascular imaging to determine the stenosis and stenosis rate. By referring to the definition of END, the incidence and time of END were compared between the two groups, and Cox multivariate regression analysis was performed for the relationship between OSAHS and END.Results There was statistically significant difference in the overall incidence of END admission between the two groups (P<0.05). The time interval between END and onset, END and admission in THE OSAHS group was smaller than that in the control group (P<0.05). After taking diabetes history, coronary heart disease history, hypertension history, thrombolytic therapy, body weight, systolic blood pressure, diastolic blood pressure, A1c, total cholesterol and other covariate factors into account, OSAHS was still a significant risk factor for END, P=0.035, RR=3.359.Conclusion OSAHS disease is a significant risk factor for END.

  Objective To study the changes of corneal biomechanical parameters of small incision lenticule extraction (SMILE) combined with corneal collagen cross-lingking (CXL) to correct myopia.Methods Prospective studies were carried out on thirty-two patients (64 eyes) who underwent SMILE surgery. They were divided into two groups according to eye exam results, including 18 petients (36 eyes ) in the SMILE group and 14 patients (28 eyes) in the SMILE combined with corneal collagen crossing-linking group (SMILE+CXL).The SMILE group received routine SMILE surgery. The SMILE+CXL group first received SMILE surgery, after the separation and removal of the corneal stroma lens, they were given Vibex Xtra riboflavin solution uniformly repeated drops in the corneal capsular bag, with 45 s, Avedro accelerate cross-linking system was used for line across epithelial rapid cross- linking, the wavelength of 365 nm was chosen, with 30 mW/cm² ultraviolet irradiation illumination for 45 s of the cornea with the continuous illumination model, and the total energy was 1.35 J/cm². The patients were followed up for 1 month and 3 months after the operation, and the basic preoperative data and postoperative ophthalmic examination parameters, corneal biomechanical parameters before and after operation, and corneal endothelial cell count were compared between the two groups.Results All the operations were completed successfully. All patients achieved or exceeded the best corrected visualacuity after the operation. The patients in SMILE+CXL group had more obvious irritation symptoms such as eye pain and tears than SMILE group. LogMAR 1 day, 1 month and 3 months after the operation were compared between the SMILE group and the SMILE+CXL group, and the difference was statistically significant (P<0.05). Comparison of spherical equivalent (SE) between the SMILE group and the SMILE+CXL group 1 day, 1 month and 3 months after surgery showed statistically significant differences (P<0.05). Intraocular pressure (IOP) was compared between the SMILE group and the SMILE+CXL group 1 month and 3 months after surgery, and the difference was statistically significant (P<0.05). Compared with 1 day after surgery, LogMAR of 1 month and 3 months after surgery was statistically significant between the two groups (P<0.05). Compared with 1 day after surgery, there was a statistically significant difference in SE between the two groups at 1 month and 3 months after surgery (P<0.05). Compared with 1 month after surgery, LogMAR difference was statistically significant in SMILE+CXL group 3 months after surgery, P<0.05. Compared with 1 month after surgery, IOP increased 3 months after surgery in both groups (P<0.05). All patients had statistically significant differences in AT1, AT2, AL1, AL2, V1, V2, HCR and DA before and after the surgery (P<0.05). Compared with the SMILE+CXL group, AT1, HCT, AL1, AL2, V1, V2 and PD showed statistically significant differences 3 months after surgery, P<0.05.Conclusion The corneal biomechanics decreased after SMILE. SMILE combined with corneal collagen cross-linking was safe and effective in early myopia correction.

  Objective To compare the effect of two different incision positions on the original astigmatism of cornea.Methods One hundred and eighty-six cases (186 eyes) of age-related cataract with preoperative astigmatism≤2.0 D in our hospital were selected as the study objects. All the patients underwent phacoemulsification combined with IOL implantation with 3.0 mm transparent corneal incision. According to the incision position, the patients were divided into group A (88 eyes) and group B (98 eyes). The incision of clear cornea was made at 10-12 points in group A, while the incision of steep corneal axis was selected in group B according to the preoperative corneal curvature examination. According to whether the preoperative astigmatism degree≤0.75 D, the changes of postoperative corneal astigmatism degree and visual acuity recovery were compared between the two groups.Results In patients with astigmatism ≤0.75 D, compared with that before surgery, the astigmatism degree decreased significantly 1 week after surgery, with P<0.05, without significant changes in astigmatism 1 month and 3 months after the operation. In patients with astigmatism≤0.75 D, compared with group A, the astigmatism degree of group B decreased significantly at different time points after the operation, P<0.05. In group B, the astigmatism degree gradually decreased with the extension of postoperative time, P<0.05.Conclusion For the patients with preoperative astigmatism≤0.75 D, the early astigmatism of different incisions decreased, but for the patients with preoperative astigmatism>0.75 D, the postoperative astigmatism decreased, and the better uncorrected visual acuity could be obtained by incision on the steep axis of cornea.

  Objective To explore the effects of different concentrations of HU-308 and nHA/PCL electrospun membranes on the biological properties of mouse pre-osteoblasts (MC3T3-E1).Methods The round electrospun membranes were placed at the bottom of the cell culture plates. MC3T3-E1 osteoblasts were inoculated and cultured in different concentrations of HU-308 (0, 10^-10, 10^-9, 10^-8, 10^-7, 10^-6 mol / L). At 1, 4, and 7 days, cell proliferation and alkaline phosphatase (ALP) activity was detected; RT-qPCR was used to detect osteoblast-related genes OPG mRNA after cultured cells for 7 days. The morphology of the cytoskeleton after 24h was observed.Results After incubation for 1, 4, and 7 days, compared with that in the control group, the proliferation activity of cells in each experimental group was enhanced, P<0.05; with the extension of incubation time, the proliferative activity of cells in the same experimental group increased gradually, P<0.05. With the extension of incubation time, ALP activity in MC3T3-E1 cells in the same experimental group increased, P<0.05. At the same time point, compared with that in the control group, the low concentration of HU-308 (10^-10 mol/L, 10^-9 mol/L) promoted the expression of OPG mRNA, P<0.05. High concentration of HU-308 inhibited the expression of OPG mRNA, and the higher the concentration was, the more significant the inhibition was, P<0.05. The results of phalloidine staining showed that the cells in the 10^-6 mol/L group had the largest spreading area and most explicit structure.Conclusion HU-308 and nHA/PCL electrospun membranes can promote the adhesion, proliferation, and differentiation of MC3T3-E1 cells.

  Myocardial reperfusion is one of the treatments for acute myocardial infarction, which can significantly improve the prognosis and reduce mortality, but it often increases myocardial cell damage in the early stage, and causes myocardial ischemia/reperfusion (I/R) injury. Autophagy is widespread in eukaryotic cells and plays a protective role in the growth and development of the body. In myocardial I/R, autophagy in the ischemic phase plays a protective role, and reperfusion phase plays a damaging role. In recent years, the mechanism of sirt1's involvement in autophagy has gradually attracted attention. Exploring the role of sirt1 in regulating autophagy in myocardial I/R injury will help to study the pathogenesis of myocardial I/R injury.
