ObjectiveTo study the sexually transmitted infections （STIs） in pregnant women with non-local household registration in Xuhui District and analyze the risk factors for STIs. MethodsFrom April 2020 to March 2022， pregnant women with non-local household registration who received their first prenatal examination in a general hospital in Shanghai Xuhui District were selected to conduct a status survey of STIs. Logistic regression model was used to analyze the influencing factors of bacterial vaginitis and ureaplasma uaplasma infection. ResultsThe top three infection rates in the pregnant women were Ureaplasma urealyticum （13.2%）， bacterial vaginosis （9.8%） and mycotic vaginitis （4.7%）. Age between 25 and 35 years （aOR=0.53，95%CI： 0.28‒0.98） and monthly income ≥8 000 yuan （aOR=0.30，95%CI： 0.11‒0.82） were significantly correlated with ureaplasma uaplasma infection. Pregnancy number of 2 （aOR=4.95， 95%CI： 1.59‒15.46）， first sexual relationship occurred before marriage （aOR=2.83， 95%CI： 1.04‒7.74）， husband's alcoholism （aOR=3.83， 95%CI： 1.08‒13.56）， high school education （aOR=0.27， 95%CI： 0.08‒0.93）， and husband's travel history （aOR=0.30， 95%CI： 0.12‒0.79） were significantly correlated with bacterial vaginitis. ConclusionPregnant women with more gestation times， first sexual intercourse before marriage and husband with heavy drinking are more likely to be infected with bacterial vaginosis. Pregnant women with younger age and lower income are more likely to be infected with Ureaplasma urealyticum. Follow-up and monitoring should be strengthened in these groups.

Objective:To comparatively analyze the diagnostic value of patent foramen ovale and the degree of right-to-left shunt among the traditional Valsalva maneuver (VM), the modified Valsalva maneuver (mVM) and the compression of the inferior vena cava combined with modified Valsalva maneuver (CM).Methods:A total of 132 patients with migraine, dizziness, chest pain and other symptoms in Longgang District People′s Hospital of Shenzhen from January 2021 to December 2021 were prospectively enrolled. The detection rate of patent foramen ovale and the degree of right-to-left shunt were assessed among the rest state and after performing the auxiliary maneuvers including VM, mVM and CM respectively.Results:After performing the auxiliary maneuvers, the detection rate of patent foramen ovale was significantly increased (88.6% vs 59.8%) with statistical significance (χ 2=36.026, P<0.001). There was a significant difference in the degree of right-to-left shunt among the three auxiliary maneuvers (χ 2=25.581, P<0.001). CM was the most effective for the detection of the large right-to-left shunt, and the difference was statistically significant compared with VM and mVM ( P<0.001, P=0.002). Conclusions:Auxiliary maneuvers is crucial for the diagnosis of patent foramen ovale. Compared with VM and mVM, performing CM can further improve the detection rate of patent foramen ovale and increase the degree of right-to-left shunt.

Objective: To explore the fear of evaluation in college student with social anxiety, in order to reveal the existence of implicit fear of evaluation and its relationships with explicit fear of evaluation. Methods: A total of 490 college students, selected from Fuzhou University by using convenience cluster sampling method, were surveyed with Interaction Anxiousness Scale (IAS). Finally, 65 valid subjects have completed the Implicit Association Test. Results: Social anxiety students explicit fear of evaluation was significantly higher than those of non social anxiety college students, including positive and negative ( t =7.03, 5.66 , P <0.01). There were significant differences between self positive evaluation of college students social anxiety (1 019.26±124.44 ms) and self neutral evaluation (909.78±175.20 ms)( t =5.67, P <0.05). In two groups of college students, there were significant differences between self negative evaluation[(1 142.54±157.06, 1 120.88± 216.33 )ms] and self neutral evaluation[(921.53±161.28, 783.72±140.74)ms]( t =9.17, 12.33, P <0.01). Implicit fear of evaluation were found to exist among students with social anxiety and without social anxiety. There was a low correlation between explicit and implicit fear of evaluation between social anxiety students and non social anxiety students( P >0.05); There was no significant gender difference between implicit and explicit fear of evaluation( P > 0.05 ). Conclusion Social anxiety college students have explicit and implicit fear of evaluation, with separate and independent effects.

To evaluate effects of reinfusion of the remaining blood filtered by leukocyte depletion filter on postoperative cellular immune function after cardiopulmonary bypass (CPB). Methods Forty patients who underwent selective cardiac valve replacement surgery with CPB in department of anesthesiology of Haikou Municipal Hospital from January to June in 2018 were enrolled. All the patients were divided into the control group and experimental group according to the random number table method, with 20 patients in each group. In the experimental group, patients received residual pump blood transfusion which had been filtered by leukocyte depletion filter and stored in sterile blood collection bags. In the control group, patients received residual pump blood transfusion which was stored in sterile blood collection bags without being filtered. The remaining blood was reinfused after CPB in two groups. Blood samples were taken before CPB (T1), 2 hours following CPB (T2), and 1, 3, 5 days after reinfusion of the remaining blood (T3, T4, T5), the levels of T lymphocyte subsets CD3+, CD4+, CD8+ and natural killer cells (NK cells) were detected by flow cytometer, and CD4+/CD8+ ratio was calculated. The levels of plasma tumor necrosis factor-α (TNF-α), interleukins (IL-2, IL-6, IL-8) were measured by enzyme linked immunosorbent essay (ELISA). The duration of mechanical ventilation, the length of intensive care unit (ICU) stay, the length of hospital stay, and incidence of wound and pulmonary infection after surgery were compared between two groups. Results Among 40 patients, there were 22 males and 18 females; with an age of (47.88±12.29) years old; and with 25 cases of American Society of Anesthesiologists (ASA) physical status Ⅱ, and 15 cases of ASAⅢ. There was no statistical difference in the volume of the remaining blood between the two groups (mL: 959.00±116.84 vs. 971.50±115.68, P > 0.05). Compared with T1, the levels of T lymphocyte subsets CD3+, CD4+, CD8+, NK cells and plasma levels of IL-2 were significantly decreased from T2, the CD4+/CD8+ ratio was significantly decreased from T3 in two groups, but there was no statistical difference in CD3+, CD4+, CD8+, NK cells, CD4+/CD8+ ratio or plasma level of IL-2 at each time between the two groups. Compared with T1, the plasma levels of TNF-α, IL-6 and IL-8 were significantly increased at T2 in two groups and then decreased gradually. The plasma levels of TNF-α, IL-6 and IL-8 from T3 in experimental group were lower than those in control group [TNF-α (ng/L): 28.49±4.66 vs. 33.82±4.30, IL-6 (ng/L): 25.98±4.51 vs. 31.38±5.42, IL-8 (ng/L):38.98±4.67 vs. 45.76±5.33, all P < 0.05], they restored to the level of T1 at T5. In addition, compared with control group, the duration of mechanical ventilation, the length of ICU stay in experimental group were significantly decreased (hours: 8.07±1.30 vs. 9.16±1.52, 28.22±2.78 vs. 31.25±3.18, both P < 0.05), and there was no statistical difference in the length of hospital stay (days: 20.65±2.76 vs. 22.45±3.22), incidence of wound and pulmonary infection (25.0% vs. 15.0%, 5.0% vs. 15.0%) between the two groups (all P > 0.05). Conclusion Reinfusion of the remaining blood filtered by leukocyte depletion filtercan inhibit inflammatory responses and don't affect the function of cellular immunity, and don't increase the incidence of infection.

Objective To evaluate the lung protection of residual pump blood processed by microaggregate blood filter-reinfusion in patients undergoing cardiac surgery under cardiopulmonary bypass (CPB).Methods A total of 40 patients,aged 28-55 yr,weighing 46-66 kg,of American Society of Anesthesiologists physical status Ⅱ or Ⅲ,with New York Heart Association of Ⅱ or Ⅲ,with left ventricular ejection fraction＞50％,scheduled for elective cardiac valve replacement under general anesthesia,were divided into 2 groups (n =20 each) using a random number table method:residual pump blood reinfusion group (group C) and residual pump blood processed by microaggregate blood filter-reinfusion group (group M).Residual pump blood was collected immediately after the end of CPB.The residual pump blood was stored in sterile blood collection bags without being filtered in group C.The residual pump blood was stored in sterile blood collection bags after being processed by microaggregte blood filter in group M.Residual pump blood was intravenously reinfused after the CPB pipe was removed.At 10 min before CPB (T1),immediately after the end ofCPB (T2),immediately after processing (T3) and at 12 and 24 h after residual pump blood reinfusion (T4,5),blood samples were collected to measure blood components and serum tumor necrosis factor-alpha and intedeukin-6 concentrations (by enzyme-linked immunosorbent assay).Airway plateau pressure was recorded,arterial blood samples were collected for blood gas analysis,and static lung compliance,oxygenation index and respiratory index were calculated at T1.5.The postoperative mechanical ventilation time,duration of intensive care unit stay,length of hospital stay,and incidence of hypoxemia and pulmonary infection were recorded.Results Compared with group C,white blood cell count was significantly decreased at T3-5,and static lung compliance and oxygenation index were increased,respiratory index was decreased,serum tumor necrosis factor-alpha and interleukin-6 concentrations were decreased,postoperative mechanical ventilation time and duration of intensive care unit stay were shortened,and the incidence of hypoxemia was decreased at T4.5 in group M (P＜0.05).Conclusion Residual pump blood proccessed by microaggregate blood filter-reinfusion can reduce systemic inflammatory responses and exerts lung protection to some extent in the patients undergoing cardiac surgery under CPB.

BACKGROUNDBu-Shen-Yi-Qi-Tang (BSYQT), which is prescribed on the basis of clinical experience, is commonly used in clinics of traditional Chinese medicine (TCM) for asthma treatment. The components of BSYQT include Radix Astragali (RA), Herba Epimedii (HE) and Radix Rehmanniae (RR). The aim of this study was to compare the effect of granules and herbs of BSYQT on airway inflammation in asthmatic mice.

METHODSSixty female BALB/c mice were randomly divided into the normal control (NC) group, asthmatic group (A), decoction of granules of BSYQT treatment group (GD), decoction of herbs of BSYQT treatment group (HD), and dexamethasone treatment group (DEX). The mouse asthmatic model was induced by ovalbumin (OVA) sensitization and challenge. GD and HD of BSYQT as well as DEX were prepared and administered by intragastric infusion. Airway hyperresponsiveness (AHR) to methacholine (Mch), lung histopathology analysis, inflammatory mediators in serum (IL-4, IL-5, IL-17A, IFN-γ, and eotaxin) and in lung (IL-4, IL-5, IFN-γ, and eotaxin) were selected for investigation and comparison.

RESULTSBoth GD and HD treatment could decrease airway resistance (RL) and increase dynamic compliance (Cdyn) to Mch compared with the A group (P < 0.05). HD treatment was more effective in RL reduction than Mch at doses of 3.125 and 6.25 mg/ml (P < 0.05) and in Cdyn increase at Mch doses of 6.25 and 12.5 mg/ml (P < 0.05). There were no marked differences in RL reduction and Cdyn improvement between mice in HD and DEX groups (P > 0.05). Both GD and HD treatment markedly attenuated lung inflammation (P < 0.05), and HD treatment demonstrated more significant therapeutic function in alleviating lung inflammation than that of GD and DEX treatment (P < 0.05). Both GD and HD treatment resulted in a significant reduction in IL-4 and IL-17A levels and an increase in the IFN-γ level in serum compared with the A group (P < 0.05). The effect of HD in lowering the IL-4 and IL-17A level was significantly greater than that of GD (P < 0.05), and was not significantly different from DEX (P > 0.05). HD treatment significantly reduced the serum level of IL-5 and eotaxin compared with the A group (P < 0.05), however, mice in the GD treatment group did not demonstrate this effect. GD and HD treatment significantly reduced IL-4 and eotaxin mRNA expression compared with the A group (P < 0.05). HD treatment significantly reduced IL-5 mRNA expression compared with the A group (P < 0.05). There was a significant difference between the GD and HD treatment groups in reducing IL-5 and eotaxin mRNA expression (P < 0.05). HD treatment was more effective in down-regulation of IL-5 in serum and eotaxin level both in serum and lung than DEX (P < 0.05). Compared with the A group, an obvious increase in mRNA expression of IFN-γ was observed in both the GD and HD treatment groups (P < 0.05). However, the effect of HD treatment on increase of IFN-γ mRNA expression was more apparent than GD and DEX treatment (P < 0.05).

CONCLUSIONSBoth GD and HD treatment could decrease AHR, attenuate lung inflammation, reduce IL-4, IL-5, IL-17A, and eotaxin levels and increase IFN-γ levels in asthmatic mice. HD treatment manifests more remarkable inhibitory effects on asthmatic inflammation than GD treatment, which could provide a guide for further research on the screening of the material basis of the best anti-inflammatory effect of BSYQT.
