Objective? To investigate the anxiety and depression of pregnant women with spontaneous abortion in the first trimester of pregnancy, and to explore the related influencing factors, so as to provide basis for clinical psychological intervention and treatment. Methods? During August 2015 to February 2016, a total of 70 pregnant women with spontaneous abortions experience and 70 primigravid women at the outpatient department of a ClassⅢ Grade A hospital in Beijing were selected by convenience sampling method. A general questionnaire, Self-rating Anxiety Scale (SAS) and Center for Epidemiologic Studies-Depression Scale (CES-D) were applied in the investigation. Results? There were 8 anxiety cases (11.43%) and 15 depression cases (21.43%) among the 70 pregnant women with spontaneous abortions experience. The scores of SAS and CES-D of the spontaneous abortions group were higher than those of the primigravid group, and the differences were statistically significant (t=2.95,2.51; P< 0.05). The age and education level of the pregnant women were positively correlated with scores SAS (P<0.05). The age, times of spontaneous abortion were positively correlated with scores of CES-D (P< 0.05). Conclusions? There is prominent anxiety and depression in the first trimester of re-pregnancy women with spontaneous abortion experience, which may be related to the age, education level and the times of spontaneous abortions. The psychological status of pregnant women with spontaneous abortion should be assessed early and appropriate psychological intervention should be given when necessary.

As the number of patients with compromised immune function increases and fungal resistance develops, so does the risk of contracting deadly fungi in humans. Both fungi and humans are eukaryotes, so identifying unique targets for antifungal drug development is difficult. In addition, the existing antifungal drugs are limited by toxicity, drug interaction and drug resistance in practical application, which leads to the increasing incidence and fatal rate of fungal infections. Therefore, it is urgent to develop new antifungal drugs. The semi-synthetic technology using microbial fermentation products from natural sources as lead compounds has become the most used method in structural modification of antifungal drugs due to its advantages of few reaction steps and easy operation. This paper will introduce the current status of natural antifungal drugs in clinical use, as well as the latest progress in the research and development of new semi-synthetic antifungal drugs, and summarize their mechanism of action, structural modifications, advantages and disadvantages, so as to provide reference for the subsequent development of new antifungal drugs.

BACKGROUNDNominal atrioventricular (AV) interval in dual chamber pacemaker (DDD) is not the best AV delay in the majority of patients with atrioventricular block. To find a simple method for optimizing AV delay adjustment, we assessed surface electrocardiography (ECG) for optimizing AV delay during dual chamber pacing.
METHODSDDD pacemakers were implanted in 46 patients with complete, or almost complete, AV block. Optimal AV delay was achieved by programming an additional delay of 100 ms, to the width of intrinsic P wave or to the interval between pacing spike to the end of P wave on surface ECG. Left ventricular (LV) end diastolic and end systolic volumes, ejection fraction and diastolic parameters were measured by Doppler echocardiography during both nominal and optimal AV delay pacing.
RESULTSCompared to nominal AV delay setting, LV end diastolic volume increased [to (53.2 +/- 11.3) ml from (50.2 +/- 10.2) ml, P < 0.05], end systolic volume decreased [to (26.1 +/- 9.0) ml from (27.9 +/- 8.2) ml, P < 0.05] during adjusted AV delay pacing, resulting in an increase in LV ejection fraction [to (68.2 +/- 5.3)% from (64.5 +/- 4.3)%, P < 0.05]. LV diastolic filling and isovolumic relaxation time were not significantly changed.
CONCLUSIONOptimization of AV delay by surface ECG is a simple method to improve LV systolic function during dual chamber pacing.

OBJECTIVETo investigate the clinicopathological characteristics, differential diagnosis and prognosis of testicular cellular fibroma.
METHODSWe comprehensively analyzed the clinical presentation, histomorphology and immunohistochemistry of a case of testicular cellular fibroma, reviewed the relevant literature, and discussed its pathological features and differential diagnosis.
RESULTSA 30-year-old man presented with complaint of discomfort and painless enlargement in the right testis. The tumor was found to be a testicular fibroma characterized by a solid, thickly or thinly encapsulated, circumscribed and gray-white mass. Microscopically, fusiform cells were arranged into a storiform and herringbone pattern or fascicles. The tumor exhibited a great deal of cellularity and no nuclear polymorphisms, with a mitotic rate of 0-1/10 HP. Immunohistochemistry showed that the tumor cells were positive for Vimentin, patchily positive for S-100 and SMA, but negative for Desmin, alpha-inhibin, CD34 and CD99. The positive rate of Ki-67 was less than 1%.
CONCLUSIONTesticular cellular fibroma is a rare testicular sex cord stromal tumor, pathologically resembling its ovarian counterpart. It can be distinguished from other testicular spindle cell tumors by morphology and immunohistochemical staining. For the treatment of testicular cellular fibroma, surgical resection often has a good prognosis.

Objectives: To assess the relationship of variation of blood pressure and neurological deterioration
(ND) in ischemic stroke patients. Methods: We recruited patients with the fi rst-ever ischemic stroke
at a teaching hospital. The National Institutes of Health Stoke Score (NIHSS) of each patient was
monitored for 2 months. ND was defi ned as an increase of ≥ 2 points in NIHSS during the fi rst 7
days after stroke. Blood pressure was measured every 6 hours for fi rst 7 days. We analyzed blood
pressure data in the fi rst 36 hours to study the relationship between variation of blood pressure and
ND. Successive variation of systolic (svSBP) and diastolic (svDBP) blood pressure was calculated
as svSBP= |SBPn+1 – SBPn
| and svDBP= |DBPn+1 – DBPn
| respectively. The largest svSBP in the
fi rst 36 hours of hospitalization or before ND was defi ned as maximum variation of systolic blood
pressure (maxvSBP). Then, the mean variation of systolic (mvSBP) and diastolic (mvDBP) blood
pressure was calculated as mvSBP= svSBP/N and mvDBP= svDBP/N respectively. Results: A total
of 121 patients were included in this study, and 38 of them had ND. The mvSBP was higher in the
ND Group (17.9±8.4 mmHg vs. 13.7±4.4 mmHg, p=0.006) but the difference in mvDBP did not
reach statistical signifi cance (9.8±3.5mmHg vs. 8.6±3.0 mmHg p=0.06). The ND Group had a larger
maxvSBP (35.2±17.2 vs. 27.6±11.6 mmHg, p =0.01), which was more frequently over 30mmHg than
that in the stable group (P=0.02).
Conclusions: A large svSBP is associated with an increased risk for ND. The study highlights the
importance of close monitoring of blood pressure in ischemic stroke patients.

OBJECTIVESTo investigate the association between genetic polymorphisms ofX-ray repair crosscomplementing group 1 (XRCC1) codons 194, 280, and 399 and cervical neoplasm susceptibility.
METHODSA community-based nested case-control study was conducted. The study population consisted of women living in Chiayi City, located in southwestern Taiwan, who had received pap smear screening between October, 1999, and December, 2000 (n=32,466). The potential cases were women having lesions greater than cervical intraepithelium neoplasm II (C1N2) reconfirmed by cervical biopsy. The potential controls (case: control=1∶2) were age matched (±2 yrs) and residency matched women who had had normal pap smears. In total, 100 cases (39 C1N2, 12 C1N3, 46 carcinoma in situ (CIS), and 3 invasive cancer) and 196 controls had the information on both questionnaire and data ofXRCC1 polymorphisms.
RESULTSThe frequency ofArg/Arg, Arg/Gln, andGln/Gln in codon 399 among cases and controls was 54% (54/100), 38% (38/100), and 8% (8/100) and 58% (114/196), 37% (73/196), and 5% (9/196), respectively, which were not significantly different. No associations were also observed betweenXRCC1 codon 194 and 280 genotypes and cervical neoplasm. While dichotomized by age (<40 vs. ≥40 yrs), smoking status (active and passive smokers vs. non-smokers), and disease status (C1N2 and C1N3 vs. CIS and invasive cancer), the results remained insignificant.
CONCLUSIONSThe present findings suggest thatXRRC1 codon 194, 280 and 399 genotypes may not influence cervical neoplasm risk in the Taiwanese population.
