Objective:To determine the levels of Th1 and Th2 type cytokines in patients with unexplained habitual abortion(UHA).Methods:A total of 54 patients with UHA were studied,including 35 cases of nonpregnant woman which were called UNP group and 19 cases of pregnant women with inevitable abortion(IEA) which were called UIEA group.15 cases of normal pregnant(NP) and 15 cases of normal nonpregnant(NNP) women were selected as control groups.Supernatants from trophoblast-activated peripheral blood mononuclear cells(PBMC) of nonpregnant women groups were tested by enzyme-linked immunosorbent assay(ELISA) for interferon gamma(IFN-?),interleukin-2(IL-2),IL-4,IL-10.Also,these cytokines were tested in the supernatants from PBMC and decidual mononuclear cells(DMC) of pregnant women groups.Results:①The levels of IL-2,IFN-? in trophoblast-activated PBMC supernatants of UNP group were higher and IL-4,IL-10 were lower than those of normal nonpregnant group( P

Objective:To study the mental state of primigravida before delivery and the effect of psychological help on their mood and delivery type.Method:272 primigravida who was just near their delivery were assessed with STAI and VAS for anxiety in Labor, 152 of them received psychological help including support from medical staff and family members in a sweet environment with accompanied family members?The other 120 primigravida received routine labor service.Result:During labor, primigravida had bad mood,psychological help deceased their anxiety and fear, and was helpful in upgrading the rate of delivery.Conclusion:Bad mood of primigravida is common, supportive attitude and environment are helpful to both mental state and their delivery.

Objective To investigate the influences of active immunotherapy on T helper cell (Th)1/Th2 type cytokines in women with unexplained habitual abortion(UHA) Methods A total of 55 patients with UHA were studied, including 30 cases after active immunotheraphy (AIT) and 25 cases without any therapy(NAIT). Fifteen cases of normal nonpregnant (NNP) women were selected as control group. Supernatants from trophoblast activated peripheral blood mononuclear cells (PBMC) of the three groups were tested by enzyme linked immunosorbent assay (ELISA) for interferon gamma (IFN ?), interleukin 2 (IL 2), IL 4, IL 10. Results (1) The levels of IL 2 and IFN ? in AIT group [(108?37) ng/L and (110 ?52) ng/L, respectively] were lower significantly than those in NAIT group[(223?85) ng/L and (326 ?92) ng/L, respectively]( P 0.05). (2) Twenty six women in AIT group got pregnant, but 8 women experienced pregnancy loss repeatedly whose IL 2?IFN ? levels were higher than those in other 18 women got successful pregnancy and IL 4,IL 10 levels lower than the latter. Conclusions UHA patients have Th1 type immunity to trophoblast and produce high level Th1 type cytokines which probably result in pregnancy loss. Active immunotheraphy could make a shift from Th1 to Th2 immunity, thus favoring the maintenance of pregnancy.

Objective To determine the influence of P-glycoprotein (P-gp) inhibitor on the blood brain barrier (BBB) transport of amphotericin B (AmB)..Methods An in-vitro BBB model was established with brain capillary endothelia cells (BCEC). AmB was chosen as the test drug and verapamil was chosen as the inhibitor of P-gp.Cellular uptake of AmB at different time points and with series of verapamil concentrations were performed respectively after the determination of appropriate incubation time and drug dosage by the cytotoxicity assay. The AmB concentrations of series of samples were detected using high performance liquid chromatography (HPLC) method. One-way ANOVA analysis and Bonferroni test were used for data analysis.Results The cellular transport of AmB was accumulated as the time prolonged.The inhibitor group had a significant higher cellular uptake levelsof AmBat the time point of 90 min (t=6.753,P=0.001),120 min (t=3.574,P=0.016) and 150 min (t=4.759,P=0.005) as compared with the control group.The AmB cellular uptake level increased significantly when BCEC were incubated with verapamil of 2 μmol/L (P=0.000),5 μmol/L (P=0.014),10 μmol/L (P=0.000),50 μmol/L (P=0.014),75 μmol/L (P=0.000) and 100 tμmol/L (P=0.000),respectively,compared with the control group.Conclusion The P-gp inhibitor verapamil can enhance the cellular uptake of AmB which indicates that P-gp is involved in the BBP transport of AmB.

Objective:To analyze the value of folate receptor-positive circulating tumor cells (FR +-CTC) in the diagnosis and efficacy evaluation of patients with small cell lung cancer (SCLC). Methods:The data of 59 patients with SCLC and 14 patients with benign pulmonary diseases treated in China-Japan Friendship Hospital from May 2017 to October 2019 were retrospectively analyzed. Folate receptor targeted detection was used to detect the level of FR +-CTC in the blood of SCLC patients. The levels of serum progastrin-releasing peptide (Pro-GRP), neuron-specific enolase (NSE), cytokeratin 19 fragment 21-1 (Cyfra21-1) , and carcinoembryonic antigen (CEA) were detected by using chemiluminescence. The median ( P25, P75) was used as all the detection indexes. Mann-Whitney U test was used for pairwise comparison, Spearman correlation test was used to analyze the correlation between two variables, and receiver operator characteristic (ROC) curve was used to evaluate the diagnostic efficacy. Results:The level of FR +-CTC in 59 patients with SCLC was 11.00 FU/3 ml (7.10 FU/3 ml, 14.50 FU/3 ml), and the positive rate of FR +-CTC in patients with SCLC was 66.10% (30/59); the level of FR +-CTC in 14 patients with benign pulmonary diseases was 6.75 FU/3 ml (5.03 FU/3 ml, 7.85 FU/3 ml), and the positive rate of FR +-CTC in 14 patients with benign pulmonary diseases was 14.29% (2/14). The level of FR +-CTC in patients with SCLC was higher than that in patients with benign pulmonary diseases, and the difference was statistically different ( U = 33.50, P < 0.01). The expression level of FR +-CTC was not related to age, gender and smoking history in SCLC patients (all P>0.05). The expression level of FR +-CTC in patients with extensive-stage was higher than that in patients with limited-stage, and the difference was statistically significant ( P < 0.05). Tumor markers Pro-GRP, NSE, Cyfra21-1 and CEA were compared with FR +-CTC, and the ROC curve was drawn; the results showed that FR +-CTC had better sensitivity (71.2%) and specificity (92.90%) in the diagnosis of SCLC. For SCLC patients who received chemotherapy, the decrease range of FR +-CTC in patients with partial remission and stable disease was greater than that in patients with the progression of disease, and the differences were statistically significant (all P < 0.05). Conclusion:FR +-CTC can assist the diagnosis and disease staging of SCLC. For patients receiving chemotherapy, continuous detection of circulating tumor cells can help to evaluate the efficacy of chemotherapy and provide a reference for the choice of clinical treatment.

Objective To investigate the clinical efficacy and safety of high-dose caspofungin (70 mg/d)as initial or salvage treatment for invasive pulmonary aspergillosis.Methods Twenty-one patients with proven or probable invasive pulmonary aspergillosis from June 2014 to October 2017 in Huashan Hospital,Fudan University were retrospectively reviewed.According to the anti-fungal treatment before high-dose caspofungin application,patients were divided into initial treatment group and salvage treatment group.Patients' clinical data and laboratory data were collected.The characteristics,clinical efficacy,adverse reactions,one-year survival rate and the overall effective rate were evaluated.The prognosis of the two groups was compared by Kaplan-Meier analysis.Results Twenty of the 21 patients opportunistic acquired invasive pulmonary aspergillosis during the treatment of underlying diseases.Five patients were initially treated with high-dose caspofungin for 68 (62) days.At week 12,one patient achieved complete response,3 patients achieved partial response,and the overall effective rate was 80％ (4/5).Sixteen patients received caspofungin as salvage therapy for 66.50 (58) days,of which one patient got complete response at week 12,10 had partial response,and the overall effective rate was 68.75％ (11/16).One-year follow-up showed that no patient died in the initial treatment group,and the one-year survival rate was 100％ (5/5).In salvage treatment group,3 patients died of pulmonary bacterial infections and the one-year survival rate was 81.25％ (13/16).During treatment,one patient had elevated total bilirubin,which was possibly associated with high-dose caspofungin.Conclusions High-dose caspofungin regimen has good efficacy and safety,both for initial treatment and salvage therapy in patients with invasive pulmonary aspergillosis.

Objective:To investigate the current situation and influencing factors of patients′ satisfaction with nursing humanistic care, and to provide reference for improving the quality of such care provided by hospitals.Methods:From July to August 2022, outpatients and inpatients in 30 provinces were selected by multi-stage stratified sampling as the survey objects. A cross-sectional survey was conducted on an online platform, using the general information questionnaire and Chinese version of methodist health care system nurse caring instrument revised by the research group. The latter instrument consists of 12 dimensions. namely care coordination, competence, teaching/learning, emotional support, respect for individuality, physical comfort, availability, helping/trusting relationship, patient/family engagement, physical environment, spiritual environment and outcomes. Descriptive analysis was performed on the data collected by the questionnaires, and independent sample t-test and one-way ANOVA were used to analyze the influencing factors of patient satisfaction. Results:A total of 107 hospitals were selected for questionnaire survey, including 86 tertiary hospitals and 21 secondary hospitals, and 29 108 valid questionnaires were recovered. The patient satisfaction with nursing humanistic care scored (5.40±0.86); the top three dimensions were competence (5.50±0.89), emotional support (5.47±0.88) and helping/trusting relationship (5.46±0.86); the lowest scoring dimensions were teaching/learning (5.38±1.01), spiritual environment (5.36±1.04) and patient/family engagement (5.11±1.28). Differences with gender, age, marital status, child status, educational level, occupation, place of residence, economic region, per capita monthly income of the family, type of medical insurance, medical department visited and surgery or not presented significant differences on the patient satisfaction with nursing humanistic care scores ( P<0.05). Conclusions:The satisfaction of patients with hospital′s nursing humanistic care in China was at the middle to upper level. In the future, health education for patients should be strengthened, and a mode of family-engaged nursing humanistic care should be constructed in line with the Chinese cultural background. In the process of nursing services, the particularity of patient groups should be considered to better meet their needs.

The COVID-19 pandemic caused by the novel SARS-CoV-2 virus has caused havoc across the entire world. Even though several COVID-19 vaccines are currently in distribution worldwide, with others in the pipeline, treatment modalities lag behind. Accordingly, researchers have been working hard to understand the nature of the virus, its mutant strains, and the pathogenesis of the disease in order to uncover possible drug targets and effective therapeutic agents. As the research continues, we now know the genome structure, epidemiological and clinical features, and pathogenic mechanism of SARS-CoV-2. Here, we summarized the potential therapeutic targets involved in the life cycle of the virus. On the basis of these targets, small-molecule prophylactic and therapeutic agents have been or are being developed for prevention and treatment of SARS-CoV-2 infection.

OBJECTIVE: To reconstruct a three-dimensional model of female urinary system based on magnetic resonance imaging (MRI) and tomography angiography (CTA) data. METHODS: MRI and CTA datasets were collected from 20 patients in our department in 2018 for reconstructing 3D models of the bladder urethra in resting state using Mimics19.0 software combined with engineering software. The metric parameters of the bladder urethra were analyzed in the reconstructed 3D model. RESULTS: The bladder and urethra were successfully reconstructed using 10 MRI datasets, and the kidney, ureter and bladder were reconstructed using 10 CTA datasets. Using engineering software, we measured a number of cysto-urethral geometric parameters, including the cysto-urethral posterior angle (151.1±17.9°), beta angle (137.3±14.0°), urethral pubic angle (47.8± 12.1°), urethral tilt angle (21.5±7.3°), alpha angle (83.8±13.8°), the posterior pubic space (15.3±3.0 mm), and the urethral striated muscle thickness (2.6±0.6 mm). CONCLUSIONS Three-dimensional reconstruction of the anatomical model of the human urinary system provides a platform for studying the fine anatomy of the female urinary system and allows measurement of multiple parameters to better understand the functional differences of the bladder and urethra in different populations.
