Objective To investigate the effect of HSP70/CD80 DNA vaccine on the airway inflammation and hyperresponsiveness of asthmatic mice. Methods Forty female healthy BALB/c mice were randomly divided into 4 groups; saline group, asthma group, pcDNA3. 1 plasmid control group, and prevention group with HSP70/CD80 DNA vaccine, with 10 mice in each group. The mice were immunized by intramuscular( i. m. ) injection with HSP70/CD80 DNA vaccine before sensitization and challenge with ovalbumin. Then, the murine model of allergic asthma was made with injection of ovalbumin intraperitoneal ( i. p. ) , and inhalation of ovalbumin. Before mice were sanctified, their airway hyperresponsiveness( AHR) was measured. After mice were sanctified, bronchoalveolar lavage fluid( BALF) was obtained and cytokine IL-13 and IFN-γ were measured. And the lung histology and histochemistry were examined. Results Compared with mice in asthma and pcDNA3. 1 group, mice in vaccine group showed significantly reduced airway inflammation (P<0. 05) and AHR (P<0. 05). IFN-γ content in BALF were increased in mice from vaccine group compared with the asthma group and the pcDNA3. 1 group ( P <0. 05) , and IL-13 content in BALF were decreased. Conclusion HSF70/CD80 DNA vaccine can reduce airway inflammation and hyperresponsiveness in asthmatic mouse and this chimerical plasmid could be a candidate vaccine to prevent asthma.

Objective To clarify the protective effect of nrsodeoxycholic acid ( UDCA ) on endoplasmic reticulum stress-mediated apoptosis in pancreatic β-cell of streptozotocin ( STZ )-induced diabetic rats.Methods Rats( n =40) received a single injection STZ( 50 mg/kg) intra-peritoneally and formed a β-cell injury model.Weight-matched normal rats( the control group,n =10 ) were injected with the buffer alone.STZ-treated rats with persistent random blood glucose higher than 16.7 mmol/L for 1 week were considered as diabetic status( n=14 ),then divided randomly into STZ-induced diabetes mellitus ( DM ) group ( n =7 ) and UDCA-treated DM group ( n =7 ).UDCA (40 mg· kg- 1,d-1 ) was administered daily by intragastric intubations throughout the experimental period (30 d).During the entire experiment,blood glucose in all rats was assessed.By the end of the experiment,all rats were sacrificed with the pancreas removed and the blood sample collected immediately.Fasting insulin levels were assayed by radioimmunoassay.The morphological changes of pancreatic β-cells apoptosis were determined by TUNEL assay.RNA in pancreas was abstracted and microarray containing 89 pieces of apoptosis related genes was applied.The related gene expressions were detected by RT-PCR and Western blot.Results The concentration of blood glucose in diabetic rats was gradually decreased after UDCA treatment,but at the end of the experiment it was still higher than that in the normal control group.The treatment with UDCA raised the fasting insulin level in diabetic rats,but this concentration was significantly lower as compared to the control group.Based on TUNEL stained tissue sections,the percentage of β-cell apoptosis of UDCA-treated DM group was significantly lower than that of STZ-induced diabetic group(P<0.05 ).Among 89 genes,42 genes up-regulated and 46 genes down-regulated in diabetic rats,some of which were ameliorated by UDCA treatment.The expressions of Caspase-3,Bax,Bip,and CHOP mRNA in pancreas of DM group were significantly up-regulated as compared with those in the control group ( P < 0.05 ) ; while the expression of Bcl-2 mRNA was markedly down-regulated (P<0.05 ).However,these parameters in the U DCA-treated animals showed a marked improvement.Conclusion Ursodeoxycholic acid seems to protect pancreatic β-cell from apoptosis in STZ-induced diabetes by attenuating the severity of endoplasmic reticulum stress.

Objective:To investigate sedation level for postoperative patients with mechanical ventilation in ICU, and to explore the related factors and patient outcomes with different sedation level.Methods:Totally 163 postoperative ICU patients from 11th June to 30th October 2018 were prospectively analyzed. Medical information and all the RASS (Richmond Agitation Sedation Scale) scores was recorded by nurses.Results:The 163 enrolled patients received 11 261.62 hours mechanical ventilation therapy, and 2 815 RASS scores were assessed and recorded by nurses. Among these scores, 80.3% (2 261/2 815) were at light sedation level, while 17.4% (490/2 815) and 2.3% (64/2 815) were at excessive or insufficient sedation level, respectively. All patients were divided into satisfactory sedation group and unsatisfactory sedation group according to the recommendations of guidelines, and used both univariate analysis and multivariate analysis. Compared to males, female patients tend to be in a satisfactory sedation level ( OR value was 0.39, P<0.05); use of midazolam may increase the risk of unsatisfactory sedation level ( OR value was 5.60, P<0.05); the longer sedation assessment interval ( OR value was 1.70, P<0.05), the more likely the patient′s sedation level is unsatisfactory ( OR value was 1.70, P<0.05) . Patients in sedation unsatisfactory group have higher rate of tracheostomy ( χ 2 value was 9.70, P<0.01), longer ICU stay ( U value was -2.33, P<0.05) and more medical expense ( t value was -4.26, P<0.01). Conclusion:The current sedation management in our ICU is satisfactory, but there is still a small part of patients in a state of insufficient sedation or excessive sedation. Sedation level is closely related to sedatives, RASS assessments interval performed by the nurses. This study provides a reference and basis for clinical sedation management and the sedation assessment strategies in the ICU.

Objective:To compare the clinical characteristics of critically ill pregnant women admitted to the intensive care unit (ICU) with different admission methods, in order to make more effective and rational use of ICU resources.Methods:A retrospective study was conducted. The clinical data of critically ill pregnant women admitted to ICU of Peking University Third Hospital from January 2006 to July 2019 were analyzed. According to the admission mode to ICU, the pregnant women were divided into emergency admission group (transferred to ICU on the same day or the next day due to critical illness) and planned admission group (transferred to ICU 2 days after admitting in obstetric ward). The clinical characteristics of ICU critical pregnant women, such as the incidence, causes of admission, severity of the disease, main treatment measures, mortality, and medical expenses were collected, and a comparative analysis between the two groups was performed.Results:During the nearly 14 years, a total of 576 critical pregnant women in ICU were enrolled, accounting for 0.8% (576/71 790) of the total number of obstetric inpatients and 4.6% (576/12 412) of the total number of ICU inpatients. Seven maternal deaths accounted for 1.2% of all critically pregnant women transferred to ICU, and the overall mortality of pregnant women was 10/100 thousand. Of the 576 critically pregnant women, there were 327 patients (56.8%) in the emergency admission group and 249 patients (43.2%) in the planned admission group. Compared with the planned admission group, the proportion of elective cesarean section in the emergency admission group was significantly lower (17.7% vs. 94.0%, P < 0.01), and the proportion of emergency cesarean section was significantly higher (65.1% vs. 2.4%, P < 0.01), the acute physiology and chronic health evaluation (APACHE Ⅱ, APACHE Ⅲ) scores, simplified acute physiology score Ⅱ (SAPS Ⅱ) and Marshall score were significantly higher [APACHE Ⅱ score: 6.0 (4.0, 9.8) vs. 4.0 (3.0, 7.0), APACHE Ⅲ score: 14.0 (11.0, 20.3) vs. 12.0 (9.0, 16.0), SAPS Ⅱ score: 8 (0, 12) vs. 3 (0, 8), Marshall score: 2 (1, 4) vs. 1 (1, 3), all P < 0.01]. The length of ICU stay in the emergency admission group was significantly longer than that in the planned admission group [days: 2 (1, 5) vs. 2 (1, 3), P < 0.01], and the total length of hospital stay was significantly shorter [days: 9 (7, 13) vs. 13 (10, 18), P < 0.01]. Both in the emergency admission group and the planned admission group, obstetric factors were the main reason for admission, 60.9% (199/327) and 70.3% (175/249), respectively. The proportion of postpartum hemorrhage was the highest [35.2% (115/327) and 57.0% (142/249)], followed by preeclampsia/eclampsia [7.0% (23/327) and 7.6% (19/249)]. Only 7 of the 19 critically pregnant women with puerperal infection were planned admission. All 21 patients with acute fatty liver of pregnancy (AFLP) during pregnancy were emergency admission. Among the emergency and planned admission patients, 73 patients (22.3%) and 42 patients (16.9%) required mechanical ventilation (duration of mechanical ventilation > 24 hours), 99 patients (30.3%) and 35 patients (14.1%) needed vasoactive agents, 67 patients (20.5%) and 20 patients (8.0%) received hemodynamic monitoring, and 123 patients (37.6%) and 154 patients (61.8%) were given anticoagulation therapy, respectively. In terms of severity score of critical pregnant women, there were significant differences in APACHE Ⅱ, APACHE Ⅲ, SAPS Ⅱ and Marshall scores of pregnant women with different diseases. Among them, the APACHE Ⅲ, SAPS Ⅱ and Marshall scores of AFLP were the highest [21.0 (15.0, 32.5), 12.0 (6.0, 16.5) and 6.0 (3.5, 8.0), respectively]. The APACHE Ⅱ and APACHE Ⅲ scores of postpartum hemorrhage were the lowest [4.0 (3.0, 7.0), 12.0 (10.0, 16.0)]. The SAPS Ⅱ score of pneumonia was the lowest [2.0 (0, 14.0)]. The Marshall score for puerperal infection was the lowest [1.0 (0, 3.0)]. In terms of the total medical expenses, the cost in the emergency admission group was significantly lower than that in the planned admission group [10 thousand Yuan: 3.1 (2.0, 4.7) vs. 4.1 (2.9, 5.8), P < 0.05]. Conclusions:Compared with the critically ill pregnant women who planned to be admitted to ICU, the patients emergency admitted to ICU were more complicated and urgent, and the severity of the condition was scored higher. At present, the severity scoring system commonly used in ICU can only partly evaluate the severity of critically ill pregnant women, therefore, it is necessary to design the specific severity scoring system for critically ill pregnant women to effectively and rationally use the precious ICU resources.

ObjectiveTo investigate the correlation between somatosensory evoked potentials (SEP) of upper limbs, and sensory and motor functions in stroke patients in different stages. MethodsFrom June, 2021 to October, 2023, 177 stroke patients in Shijiazhuang People's Hospital were diveded into acute stage group (within 14 days, n = 25), early recovery group (14 days to one month, n = 110) and middle to late recovery group (one to six months, n = 42) according to the duration of the disease. General information of the patients was recorded; SEP examination was performed, and N20 lantency and amplitude were recorded. Monofilament touch and two-point discrimination sensation of the patient's hands were tested using the monofilament and two-point discrimination tools, respectively; and motor function was assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE). The correlation between SEP, and the sensory and motor scores in each group was analyzed. ResultsThere was no significant difference in the monofilament tactile and two-point discrimination scores among the three groups (P > 0.05). SEP was not correlated with sensory and motor functions in the acute stage group (P > 0.05); in the early recovery group, N20 latency was negatively correlated with monofilament tactile sensation (r = -0.267, P = 0.005) and positively correlated with two-point discrimination sensation (r = 0.220, P = 0.021), and N20 amplitude was positively correlated with monofilament tactile sensation (r = 0.328, P < 0.001) and FMA-UE score (r = 0.418, P < 0.001), and negatively correlated with two-point discrimination (r = -0.405, P < 0.001); in the middle to late recovery group, the N20 latency was negatively correlated with FMA-UE score (r = -0.313, P = 0.044), and N20 amplitude was positively correlated with monofilament tactile sensation (r = 0.598, P < 0.001) and FMA-UE score (r = 0.393, P = 0.010), and negatively correlated with two-point discrimination (r = -0.591, P < 0.001). Multiple linear regression analyses showed that the score of monofilament tactile sensation was negatively correlated with N20 latency (β = -0.510, P = 0.046), and the FMA-UE score was positively correlated with N20 amplitude (β = 0.313, P = 0.026) in the middle to late recovery group; in the early recovery group, the two-point discriminative sensation score was negatively correlated with N20 amplitude (β = -0.270, P = 0.039). ConclusionThe correlation between SEP and sensory and motor functions becomes more significant with the prolongation of disease.

BACKGROUND:
Anorexia nervosa (AN) is a psychological disorder, which is characterized by the misunderstanding of body image, food restriction, and low body weight. An increasing number of studies have reported that the pathophysiological mechanism of AN might be associated with the dysbiosis of gut microbiota. The purpose of our study was to explore the features of gut microbiota in patients with AN, hoping to provide valuable information on its pathogenesis and treatment.
METHODS:
In this cross-sectional study, from August 2020 to June 2021, patients with AN who were admitted into Peking University Third Hospital and Peking University Sixth Hospital ( n = 30) were recruited as the AN group, and healthy controls (HC) were recruited from a middle school and a university in Beijing ( n = 30). Demographic data, Hamilton Depression Scale (HAMD) scores of the two groups, and length of stay of the AN group were recorded. Microbial diversity analysis of gut microbiota in stool samples from the two groups was analyzed by 16S ribosomal RNA (rRNA) gene sequencing.
RESULTS:
The weight (AN vs. HC, [39.31 ± 7.90] kg vs. [56.47 ± 8.88] kg, P < 0.001) and body mass index (BMI, AN vs. HC, [14.92 ± 2.54] kg/m 2vs. [20.89 ± 2.14] kg/m 2 , P < 0.001) of patients with AN were statistically significantly lower than those of HC, and HAMD scores in AN group were statistically significantly higher than those of HC. For alpha diversity, there were no statistically significant differences between the two groups; for beta diversity, the two groups differed obviously regarding community composition. Compared to HC, the proportion of Lachnospiraceae in patients with AN was statistically significantly higher (AN vs. HC, 40.50% vs. 31.21%, Z = -1.981, P = 0.048), while that of Ruminococcaceae was lower (AN vs. HC, 12.17% vs. 19.15%, Z = -2.728, P = 0.007); the proportion of Faecalibacterium (AN vs. HC, 3.97% vs. 9.40%, Z = -3.638, P < 0.001) and Subdoligranulum (AN vs. HC, 4.60% vs. 7.02%, Z = -2.369, P = 0.018) were statistically significantly lower, while that of Eubacterium_hallii_group was significantly higher (AN vs. HC, 7.63% vs. 3.43%, Z = -2.115, P = 0.035). Linear discriminant effect (LEfSe) analysis (LDA score >3.5) showed that o_Lachnospirales, f_Lachnospiraceae, and g_Eubacterium_hallii_group (o, f and g represents order, family and genus respectively) were enriched in patients with AN. Microbial function of nutrient transport and metabolism in AN group were more abundant ( P > 0.05). In AN group, weight and BMI were significantly negatively correlated with the abundance of Bacteroidota and Bacteroides , while positively correlated with Subdoligranulum . BMI was significantly positively correlated with Firmicutes; HAMD scores were significantly negatively correlated with Faecalibacterium.
CONCLUSIONS
The composition of gut microbiota in patients with AN was different from that of healthy people. Clinical indicators have correlations with the abundance of gut microbiota in patients with AN.
