Objective:To figure out the clinical factors contributing to the oocytes utility rate (OUR) of high responders in in vitro fertilization (IVF)-embryo transfer treatment.Methods:OUR was defined by the number of usable embryos for transfer and (or) cryopreservation divided by the number of oocytes retrieved in a freeze-all cycle. The cycles with ≥15 eggs were included from January 2013 to December 2019. Those with OUR at the top 10% (Group A) and the bottom 10% (Group B) were picked and compared for patients′ characteristics, parameters relating to ovary stimulation and pregnant outcomes. Multifactorial logistic regression was applied to reveal the risk factors affecting OUR in them.Results:A total of 43 patients were included in Group A (OUR: 77.4%, 601/776) and 47 for Group B (OUR: 11.9%, 104/874). Previous IVF/intracytoplasmic sperm injection (ICSI; OR=0.10, 95% CI: 0.01-0.81) and endometriosis ( OR=0.16, 95% CI: 0.03-0.84) were negative factors for OUR ( P<0.05); dual suppression protocol ( OR=3.74, 95% CI: 1.06-26.86) and longer days of stimulation ( OR=3.24, 95% CI: 1.25-8.42) were protective factors in terms of ovarian stimulation ( P<0.05), on contrary to that, any decline of estradiol during the stimulation led to poorer OUR ( OR=0.16, 95% CI: 0.04-0.64). Although two groups had similar quantities of eggs and metaphase of meiosis Ⅱ (MⅡ) oocytes, distinguished cumulative clinical pregnancy rate and cumulative live birth rate were seen in Group A and group B respectively [95.3% (41/43) vs 40.4% (19/47) and 90.7% (39/43) vs 31.9% (15/47), all P<0.01]. Conclusions:High responders with attempted IVF/ICSI and endometriosis should be considered as risk factors for OUR. Over ovarian stimulation, dual suppression and a slightly longer stimulating duration could be tried; besides, estradiol decline should be prevented for a better OUR.

OBJECTIVETo observe the therapeutic efficacy and safety of gonadotropin-releasing hormone agonist (GnRHa) combined Wenshen Xiaozheng Decoction (WXD) in auxiliary treating endometriosis after laparoscopy.

METHODSOne hundred and thirty-four endometriosis patients with confirmative pathological diagnosis were assigned to three groups depending on whether they would receive adjuvant therapy or Chinese medicine treatment, i.e., the control group, the observation 1 group, and the observation 2 group. The 22 patients in the control group received no adjuvant therapy after laparoscopy. The 42 patients in the observation 1 group were treated with GnRHa 3.6 mg by subcutaneous injection starting from the 1st day to the 5th day of menstruation, once per 28 days. The 70 patients in the observation 2 group were treated with GnRHa 3.6 mg by subcutaneous injection in combination with WXD starting from the 1st day to the 5th day of menstruation, once per 28 days. They also took WXD for 7 doses, one cycle per every 28 days. The treatment lasted for three to six months. Serum levels of estradiol (E2), follicle-stimulating hormone (FSH), luteinizing hormone (LH), and cancer antigen 125 (CA125), as well as clinical efficacy, and adverse drug reactions were observed before and after treatment.

RESULTSThere was statistical difference in serum levels of E2, FSH, or LH between the control group and the observation 1 and 2 groups (P < 0.05). There was no statistical difference in serum levels of E2, FSH, or LH between the observation 1 group and the observation 2 group (P > 0.05). There was statistical difference in the clinical efficiency among the 3 groups (P < 0.05). There was statistical difference in the pre-post difference of CA125 levels among the three groups (P < 0.01). Compared with the control group, there was no statistical difference in the pre-post difference of CA125 levels between the observation 1 group and the observation 2 group (P > 0.05). No obvious adverse reaction occurred during the treatment.

CONCLUSIONSGnRHa combined WXD showed confirmative clinical efficacy in treating endometriosis after laparoscopy. It also could lower serum levels of E2, FSH, and LH levels. So it was an ideal solution for treatment of endometriosis.

Objective To investigate the changes of serum soluble factor-related apoptosis (sFas) and soluble Fas ligand (sFasL) and their relations with cognition disorders in the patients with vascular dementia (VaD). Methods Serum concentrations of sFas and sFasl were detected by enzyme-linked immunosorbent assay (ELISA) and compared between 70 patients with VaD aged (72.5± 7.5)years and 50 healthy elderly people aged(72.5 ± 7.5)years.The VaD patient's cognitive functions were evaluated by activity of daily living scale (ADL),mini mental state examination (MMSE) and hachinski ischemia score (Hachinski). Results The serum levels of sFas and sFasL in VaD patients were (228.0±60.7)μg/L and (146.8±30.1)μg/L,and in the healthy elderly were (62.4±22.6)μg/L and (82.3 ± 18.7)μg/L,respectively.The serum levels of apoptosis factors in VaD patients were significantly higher than in the healthy controls (t=20.883,14.453,P＜0.01).sFas level was negatively correlated with age,the scores of ADL and Hachiuski while positively with the scores of MMSE (r=-0.956,-0.943,-0.950 and 0.904,all P＜0.01). sFasL level was negatively correlated with the scores of MMSE while positively with age,the scores of ADL and Hachinski (r=-0.899,0.963,0.948 and 0.939,a11 P＜0.01). Conclusions Apoptosis may be involved in the pathological change during VaD and the serum levels of sFas and sFasL might be related with cognition disorders.

The stems and branches of Hypericum petiolulatum were extracted by alcohol and liquid-liquid extraction. Seven furofuran lignans were isolated from the ethyl acetate fraction of ethanol extract of H. petiolulatum by using silica gelchromatography, Sephadex LH-20 chromatography, medium-pressure liquid chromatography and preparative HPLC. Their structures were identified by the spectroscopic methods as pinoresinol (1), medioresinol (2), 8-acetoxypinoresinol (3), epipinoresinol (4), (+)-syringaresinol (5), (+)-1-hydroxysyringaresinol (6) and erythro-buddlenolE (7). All the isolates were firstly found in H. petiolulatum.

Objective To study the hepatocyte cells infected by hepatitis C virus (HCV) positive serum. Methods Human hepatocyte 7701 was incubated with HCV RNA-positive and HCV antibody(Ab) negative sera BP52. Then, the expression of HCV antigen and the presence of HCV-RNA in cell and supernatant were assayed by RT-PCR, sequence analysis, immunofluorescent staining, Western blot, confocal laser microscopy. The ultrastructural changes of infected cells were observed by electro-microscopy. Results Plus-strand RNA and minus-strand RNA were intermittently detected in cell and/or supernatant on day 7-45 after infection. Sequence analysis demonstrated that the positive DNA nucleic acids were identified with HCV 5′-non-coding region(NCR) sequence. HCV core and NS3 protein were expressed in cytoplasm of infected cells. After 2 or 3 weeks, obvious intracellular ultrastructural changes and virus-like particles were observed. Conclusion human hepatocyte 7701 could support replication of HCV in vitro, which could be a useful tool for setting up cell model of HCV infection and studying the mechanism of HCV infection.

With low molecular weight chitosan and poloxamer 188 as the joint carriers, ginsenoside Rg3 solid dispersions were prepared by using the solvent evaporation method for an in vitro dissolution test. Subsequently, differential scanning calorimetry (DSC), scanning electron microscopy (SEM) and X-ray diffraction (X-RD) were adopted for a phase analysis. The results showed that the 60 min in vitro cumulative dissolution rate of ginsenoside Rg3 solid dispersions prepared with low molecular weight chitosan and poloxamer 188 at the ratio of 2:1 exceeded 90%, and the drug was dispersed in carriers in an amorphous state. Therefore, ginsenoside Rg3 solid dispersions prepared with low molecular weight chitosan and poloxamer 188 could help significantly improve the drug dissolution, with a practical application value.

OBJECTIVETo explore the correlation between hand and face-mouth, so as to provide nerve reflex basis for the theory "Hegu (LI 4) regulates face and mouth".

METHODSSeven hundred and sixty-three participants who met the inclusive criteria were divided into different age groups. The skin around participants' thenar eminence was gently scraped to be observed whether there was an involuntary movement around the face or mouth, which was palmomental reflex. The results of palmomental reflex were recorded.

RESULTSThe total occurrence rate of palmomental reflex was 46.26%. For those who were 0 to 1 years old, the palmomental reflex was all positive; for those who were 21 to 36 years old, the positive rate was 20.45%, which was the lowest; for those who were 65 to 85 years old, more than half of them were positive. The majority of those who were 0 to 2 years old were bilateral positive palmomental reflex, while the majority of those who were 65 to 85 years old were unilateral positive palmomental reflex.

CONCLUSIONThere is a certain connection between hand and face-mouth. The occurrence rate of palmomental reflex changes from high to low over age increasing, and then changes from low to high with the aging, presenting a "high-low-high" U-shaped curve, which is possible related to the growth and recession of nervous system.
