ABSTRACT
Objective:To explore the potential categories of post-traumatic stress disorder (PTSD) trajectories in women with multiple in vitro fertilization-embryo transfer (IVF-ET) failures, and to analyze the effects of different demographic characteristics and psychological factors on the potential categories of PTSD trajectories.Methods:This was a prospective empirical research, from May 2021 to October 2022, women with IVF-ET failure ≥ 2 times in the reproductive department of Shanghai First People′s Hospital from May 2021 to October 2022 were selected as the research objects. Post-traumatic stress disorder civilian version scale was used for 4 follow-ups at 3 d (T1), 10 d (T2), 20 d (T3) after the last transplantation failure and 3 d before the next transplantation cycle (T4). Telephone follow-up and online follow-up were combined to obtain the PTSD level at 4 time points. Potential categories of PTSD score trajectories at four time points were identified using a latent category growth model, and analyze influencing factors using unordered multi classification logistic analysis.Results:Totally 196 IVF-ET women were admitted, aged (29.42 ± 4.13) years. Three PTSD trajectories were fitted in this study, including 82 cases (42%) in non-PTSD group, 61 cases (31%) in mild PTSD group and 53 cases (27%) in elevated PTSD group. Logistic regression analysis showed that age, education level, fertility pressure and marital adjustment level were the predictors of PTSD trajectory in women with multiple IVF-ET failures. Compared with the non-PTSD group, women aged ≥35 years, with lower education level and marital adjustment level were more likely to enter the elevated PTSD group ( OR=4.570, 8.540, 0.949, all P<0.05). Women aged 35 years and with greater reproductive pressure were more likely to enter the mild PTSD group ( OR=3.871, 1.063, both P<0.05). Conclusions:There is group heterogeneity in the trajectories of PTSD in women with multiple IVF-ET failures in the next transplantation cycle. Old age, low education level, high fertility pressure and poor marital adjustment can predict the trajectories of PTSD. Fertility stress and marriage adjustment are changeable variables. Medical staff can relieve women′s fertility pressure through health education and mindfulness intervention, promote a good state of marriage adjustment, and minimize the adverse effects of PTSD on the next cycle of conception.

ABSTRACT
Objective To investigate the expression and clinical significance of androgen receptor (AR) and embryonic stem cell associated transcripts 4 (NANOG) in breast cancer patients with human epidermal growth factor receptor 2 (HER-2) over-expression, and to analyze its relationship with clinicopathologic features of breast cancer. Methods 143 breast cancer patients with HER-2 over-expression were selected from the screening of 1052 cases of invasive breast cancer according to estrogen receptor (ER), progesterone receptor (PR) and HER-2 status. The protein expression of AR and NANOG was assayed by using immunohistochemistry.The relationship between AR expression and clinicopathological features was analyzed by χ2 test. The correlation between AR expression and NANOG expression was analyzed by Spearman correlation analysis. Results The positive expression of AR was 35.7 % (51/143). The AR expression was not associated with age and menstruation status (both P>0.05), and was associated with tumor size, clinical TNM staging and lymphatic metastasis (all P< 0.05). The positive rate of NANOG were 53.1 %(76/143), and NANOG proteins were negative in adjacent normal breast tissue and benign breast lesions. The positive rate of AR was 27.6%(21/76) in NANOG-positive cases, whereas the positive rate of AR was 44.8%(30/67) in NANOG-negative cases, and the difference was statistically significant (χ2=4.526, P=0.033). There was an inverse correlation between NANOG and AR expressions (r= -0.255, P= 0.002). Conclusion AR and NANOG may be new targets for endocrine therapy and molecular biological therapy.

ABSTRACT
Objective To study the incidence of PTEN, p53 and Ki-67 expression in astrocytoma and show the relationship between PTEN, p53 expression and the proliferation activity. Methods The surgical specimens from 68 brain astrocytoma patients were analysed to detect PTEN, p53 and Ki-67 expression with immunohistochemical method. Results The incidence of PTEN, p53 and Ki-67 expression was 54.4 %,45.6 % and 48.5 % respectively in astrocytoma. With the grade of astrocytoma increasing the levels of PTEN protein decreased, on the other hand the levels of p53, Ki-67 increased. There was a negative correlation between PTEN expression and grade of astrocytoma while there was a positive correlation between p53, Ki-67 expression and grade of astrocytoma by using the Spearman Correlation test to analyse the data. The incidence of Ki-67 positive expression was 24.3 % in 37 cases exhibiting PTEN positive staining, whereas the incidence of Ki-67 positive expression was 77.4 % in 31 cases exhibiting PTEN negative staining. In statistics, there was an inverse correlation between PTEN and Ki-67 expression. Conclusion There is an inverse correlation between histopathological grades of astrocytoma and PTEN expression. A positive correlation is found between p53, Ki-67 expression and histopathological grades of astrocytoma. PTEN can inhibit tumor cell proliferation in astrocytoma.
ABSTRACT
Objective To screen the potent permeation enhancers used in transcutaneous immunization with inactivated highly pathogenic avian influenza vaccine. Methods Five different permeation enhancers, ethanol, propylene glycol, dimethyl sulfoxide, ratinoic acid, oleic acid, were used to treat the skin of BALB/c mice before transcutaneous immunization. Sera were collected before the flist transcutaneous immunization and every two weeks post immunization. The titers of influenza virus-specific humoral IgG and IgA were assayed in serum, lung and nasal lavages by ELISA. The titers of hemagglutination inhibition ( HAI), IFN-γand IL-4 produced by splenic lymphocytes were also detected. Except that, clinical symptom of the skin in different time points and skin pathological changes were observed. Results The serum IgG titers, HAI titers and the influenza virus-specific lgA and IgG in lung and nasal lavages in the groups of HA +CT + DMSO, HA + CT + RA and HA + CT + OA were significantly higher than those of HA and HA + CT groups( P ＜0.05). Moreover, the numbers of splenic lymphocytes producing IFN-γ and IL-4 were increased in the above three groups than those in control groups. In addition, no evident clinical symptoms were observed, but stratum corneum of the skin in different groups showed different changes. Conclusion DMSO,RA and OA are potent permeation enhancers in mouse model inoculated with inactivated high pathogenic avian influenza vaccine transcutaneously.

ABSTRACT
PTEN is a candidate tumor suppressor which has sequence homology with dual-specificity phosphatase. PTEN is a multifunctional protein endowed with a phosphatase activity capable of dephosphorylating both tyrosine phosphate, serine/threonine phosphate residues on proteins and phospholipids of the phosphatidylinositol pathway. PTEN appears to be mutated at considerable frequency in several types of human tumors, including those from brain, breast, endometrium, and prostate. PTEN play an important role in pathogenesis of tumor, tumor cell invasion and metastasis. In this review, we will discuss the chemical structure of PTEN, its phosphatase activity, the ability of affecting signal transduction, and its mutational status in cancer.
