ObjectiveTo investigate the prevalence rate and influencing factors of sleep insufficiency in medical students with migraine， and to provide a reference for alleviating the sleep problems in medical students. MethodsFrom July 2018 to July 2019， a random cluster sampling method was implemented to choose 546 medical students who met the diagnostic criteria of the International Classification of Headache Disorders， third edition （ICHD-3） for migraine in North Sichuan Medical College. Students were divided into sleep sufficiency group （n=367） and sleep insufficiency group （n=179） based on whether the nightly sleep duration was more than 6 hours. General demographic and clinical data of medical students were collected. Pittsburgh Sleep Quality Index （PSQI） was used to assess the sleep quality. Hamilton Anxiety Scale （HAMA） and Hamilton Depression Scale-24 item （HAMD-24） were used to evaluate the anxiety and depression states. Visual Analogue Scale （VAS） was adopted to assess the pain degree， and the 6-item Headache Impact Test Questionnaire （HIT-6） was applied to evaluate the impact of headache on daily life. Then Logistic regression analysis was conducted to screen the influencing factors of sleep insufficiency in medical students with migraine. ResultsAmong 546 medical students with migraine， 179（32.78%） had sleep insufficiency. There were significant differences in age （t=2.107）， frequency of headache attacks （Z=-2.972）， anxiety status （χ²=14.053）， depression status （χ²=10.773）， total score of PSQI （t=-13.247） and sleep quality （χ²=94.754） between sleep sufficiency group and sleep insufficiency group （P<0.05 or 0.01）. Correlation analysis showed that sleep duration in migraine patients was negatively correlated with age （r=-0.100， P<0.01）， and positively correlated with frequency of headache attacks， anxiety status， and depression status （r=0.135， 0.169， 0.139， P<0.01）. Multivariate Logistic regression analysis denoted that age （OR=0.860， 95% CI： 0.743~0.996， P=0.045）， frequency of headache attacks （OR=1.051， 95% CI： 1.006~1.098， P=0.026） and depression status （OR=1.712， 95% CI： 1.024~2.861， P=0.040） were influencing factors of sleep insufficiency in medical students with migraine. ConclusionMedical students with migraine suffer a high prevalence rate of sleep insufficiency， moreover， the frequency of headache attack and depression status are risk factors， and age is a protective factor for sleep insufficiency in medical students with migraine.

Objective:To investigate the incidence and clinical characteristics of renal involvement with Omicron coronavirus infection in age-based stratified patients.Methods:The first batch of 430 convalescent patients with Omicron coronavirus treated in Tianjin First Central Hospital from January 21, 2022 to March 7, 2022 were enrolled in this study. The baseline information, vaccination status and laboratory examination information of patients were extracted in order to analyze the incidence of renal involvement in age-based stratified patients. Multivariate Logistic regression analysis was conducted to determine the risk factors of renal involvement in different age groups.Results:Excluding those younger than 1 year old and those with a history of chronic kidney disease, a total of 421 patients were included. There were 184 males and 237 females with an average age of (36.65±21.28) years. The types of renal involvement included pathological tubular urine (28.9%), proteinuria (16.9%), renal hematuria (14.7%), a slight decrease of estimated glomerular filtration rate (eGFR, 9.3%), renal glycosuria (0.5%). According to their age, all patients were divided into three groups: 113 cases of ≤ 18 years old, 244 cases of 19-59 years old and 64 cases of ≥ 60 years old. Significant difference was founded in the incidence of renal involvement among the three groups. The incidence of proteinuria, pathological tubular urine and slight decline of eGFR in the ≥ 60 years old group were significantly higher than those in the ≤ 18 years old group [28.1% (18/64) vs. 8.0% (9/112), 42.2% (27/64) vs. 19.6% (22/112), 34.9% (22/63) vs. 6.2% (7/113), respectively, all P < 0.01]. The incidence of slight decline of eGFR was significantly higher than that in 19-59 years old group [34.9% (22/63) vs. 4.1% (10/243), P < 0.01]. Multivariate Logistic regression analysis showed that age was significantly correlated with renal involvement after adjusting for the baseline situation, serological indexes and Omicron infection related indexes [odds ratio ( OR) = 1.059, 95% confidence interval (95% CI) was 1.021-1.097, P = 0.002]. Compared with the group ≤ 18 years old, the risk of renal involvement in the group ≥ 60 years old was significantly increased ( OR = 26.245, 95% CI was 1.357-507.458, P = 0.031). Age ≥ 60 years old was an independent risk factor for renal involvement with Omicron coronavirus infection. Conclusions:Although a low incidence of severe cases in Tianjin first batch of 430 patients with Omicron coronavirus infection, there is still a high incidence of renal involvement. Advanced age is the risk factor of renal involvement. We should pay more attention to the renal involvement of elderly with Omicron coronavirus infection.

Objective To enhance patients' abilities in self-management. Methods We used the nursing project method to analyze reasons and develop standard process of follow-up management and health education. A retro-spective analysis of 84 patients with stage 3 to 4 CKD was performed by nursing project method. This analysis compared the changes after the intervention program,including the ability of self-management,follow-up,medication and diet compliance,and the control rate of physiological indicators. Results By comparison with the intervention before and after,there were significant improvements in each dimension of self-management ability (P<0.001),follow-up, medication and diet compliance were significantly improved(P<0.05),and there were significant improvements in the control rate of systolic pressure and blood uric acid(P<0.001),the differences were statistically significant. Conclusion The application of nursing project can improve self-management ability,the compliance of follow-up,medication and diet as well as physiological indicators in patients with stage 3 to 4 CKD.

Objective To investigate the impact of relevant factors in mechanical ventilation on intraabdominal pressure in patients with ALI/ARDS by continuous monitoring of intra-abdominal pressure.Methods A total of 116 ALI/ARDS patients treated with mechanical ventilation in ICU were enrolled in this study.Intra-abdominal pressure (IAP) was recorded continuously.Meanwhile ventilator parameters, arterial blood gas analysis, hemodynamic variables, and as well as the levels of IL-4, IL-8 and TNF-α in blood and bronchial alveolar lavage fluid (BALF) were determined and recorded.The detection of risk factors for intra-abdomen hypertension (IAH) were carried out using multivariate stepwise logistic regression.ROC curve analysis used to estimate the diagnostic performance of these parameters for IAH.Results The oxygenation index (PaO2/FiO2) in patients with IAH after 2 hours' mechanical ventilation was significantly lower than that in patients with normal intra-abdomen pressure (IAP) (P ＜ 0.01);PEEP and RR in mechanical ventilation were higher in IAH group (P ＜ 0.01 or P =0.001);Mean artery pressure (MAP), ejection time percent (ET), stroke volume (SV), cardiac index (CI) were lower in IAH group than those in normal IAP group (P ＜ 0.01);the levels of IL-4, IL-8 and TNF-α in blood and bronchial alveolar lavage fluid were higher in IAH group than those in normal IAP group (P ＜ 0.01);IAH patients have a higher mortality on 28 d (Log rank test, P =0.023).Poor oxygenation index (PaO2/ FiO2) after 2 hours' ventilation, high PEEP setting, low MAP, ET, SV, CI and elevated IL-4 in the BALF were resulted in increasing risk of IAH for ARDS patients under mechanical ventilation support.Conclusions The monitoring of intra-abdominal pressure should be emphasized for ALI/ARDS patients when mechanical ventilation was employed.PaO2/FiO2, SV and IL-4 in BALF might be the independent risk factors of IAH.

Objective To explore the clinical effect of traditional Chinese medicine (TCM) dialectical therapy for treatment of gastrointestinal dysfunction in patients with acute lung injury / acute respiratory distress syndrome(ALI/ARDS)undergoing mechanical ventilation. Methods A prospective,randomized controlled trial was conducted. Ninety-six ALI/ARDS patients admitted in intensive care unit(ICU)and treated with mechanical ventilation in Tianjin First Central Hospital were chosen and randomly divided into traditional Chinese medicine(TCM) group and conventional therapy group using a random number table,48 patients in each group. Conventional therapy alone was used in conventional therapy group,and TCM therapy of primarily using Dachengqi decoction combined with conventional therapy was applied in TCM group〔Dachengqi decoction was composed of mongolian milkvetch root 15 g, pilose asiabell toot 15 g,Chinese angelica 10 g,officinal magnolia bark 10 g,tangerine peel 10 g,immature tangerine fruit 10 g,peach seed 10 g,white peony root 12 g,red peony root 12 g,immature bitter orange 6 g,mongolian dandelion herb 30 g,radish seed(stir-fried)30 g,foxtail millet sprout 20 g,barley sprout 20 g,glauber salt 9 g (with water),rhubarb 10 g(added in water at last)〕,one dose orally taken daily for 28 days. The intra-abdominal pressure(IAP),gastrointestinal diseases in TCM symptom score and the incidence of gastrointestinal dysfunction were compared between the two groups before treatment and on the 3rd,6th and 8th day after treatment. Results There were no statistical significant differences in IAP and TCM symptom scores between the two groups before treatment (both P>0.05),but after treatment with the prolongation of therapeutic time the IAP and TCM symptom scores were decreased gradually compared with those before treatment,having reached the valley value on the 18th day and the changes in TCM group were more remarkable〔IAP(mmHg,1 mmHg=0.133 kPa):0.91±0.69 vs. 2.08±0.92, TCM symptom score:48.33±10.41 vs. 88.33±20.21,both P<0.05〕. In the TCM group,the incidences of the untoward symptoms and signs of gastrointestinal dysfunction such as bleeding of stress ulcer,toxic intestinal paralysis, abdominal distension,diarrhea and so on were lower than those in conventional therapy group〔stress ulcer bleeding:16.7%(8/48)vs. 39.6%(19/48),toxic intestinal paralysis:16.7%(8/48)vs. 43.8%(21/48),abdominal distension:10.4%(5/48)vs. 37.5%(18/48),diarrhea:6.3%(3/48)vs. 33.3%(16/48),all P<0.05〕. Conclusion Addition of TCM Dachengqi decoction on conventional treatment can effectively lower the incidence of gastrointestinal dysfunction in treatment of patients with ALI/ARDS undergoing mechanical ventilation.

Objective To study the feasibility of the acute gastrointestinal injury (AGI) classification standard for evaluation of gastrointestinal function in intensive care unit (ICU) patients,and to discuss its value in administration of early enteral nutrition (EN).Methods A perspective study was conducted.85 patients with AGI admitted to ICU of Tianjin First Center Hospital from January 2013 to June 2013 were enrolled.EN was conducted after ICU admission or within 12-24 hours after high catabolic state.The patients were divided into four groups according to the AGI classification,i.e.grade Ⅰ,Ⅱ,Ⅲ,and Ⅳ,and they were treated according to the treatment procedure for AGI.The primary end points were 7-day rate of intake of standard EN,the degree of disease and nutrition,and their correlation with AGI classification.Secondary endpoint was rate of giving EN within 48 hours.Results Gastrointestinal dysfunction patients accounted for 49.42％ (85/172) of the ICU patients,and number of patients in grade Ⅰ,Ⅱ,Ⅲ,Ⅳ were 29,28,19,9 respectively.On the first day of ICU stay,there were no statistical differences in age,acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score,serum albumin (ALB) and prealbumin (PA) among four groups,and it was demonstrated that the baseline data were comparable.APACHE Ⅱ score on the seventh day of ICU stay was significantly lower than that on the first day in grade Ⅰ,Ⅱ and Ⅲ patients (grade Ⅰ:20.48 ± 2.45 vs.22.59 ± 2.06,t=-3.120,P=0.031 ; grade Ⅱ:19.34 ± 1.80 vs.21.65 ± 2.22,t=-4.316,P=0.012; grade Ⅲ:20.63 ± 1.34 vs.23.31 ± 1.70,t=-5.640,P=0.000),and serum PA (g/L) was significantly increased (grade Ⅰ:24.37 ± 6.54 vs.10.62 ± 7.24,t=-4.866,P=0.000; grade Ⅱ:19.79± 12.48 vs.11.57±8.94,t=-2.116,P=0.031; grade Ⅲ:19.15±8.43 vs.13.78 ± 6.59,t=-3.601,P=0.000).On the seventh day ofICU stay,the APACHE Ⅱ score was higher in grade Ⅳ than that in grade Ⅰ,Ⅱ and Ⅲ patients (22.87 ± 3.31 vs.20.48 ± 2.45,19.34 ± 1.80,20.63 ± 1.34,P＜0.05 or P＜0.01),and PA was obviously lower in grade Ⅳ than that in grade Ⅰ,Ⅱ and Ⅲ patients (g/L:14.02 ± 8.70 vs.24.37 ± 6.54,19.79 ±12.48,19.15 ± 8.43,P＜0.05 or P＜0.01).There was no statistically significant difference among four groups in respect of serum ALB (F=0.454,P=0.722).The rate of giving EN in 24 hours in grade Ⅰ,Ⅱ,Ⅲ,Ⅳ patients was 95.4％,72.1％,52.0％ and 0,respectively (x2=8.310,P=0.016),and in 48 hours it was 100.0％,83.0％,76.0％,and 0 (x2=5.470,P=0.025).7-day standard EN intake rate was 100.0％,88.7％,84.0％ and 34.0％ respectively in grade Ⅰ,Ⅱ,Ⅲ,Ⅳ patients (x2 =0.720,P=0.017).Correlation analysis showed that there was a negative correlation between AGI classification and rate of giving EN in 1 day (r=-0.62,P=0.04) and 7-day standard EN intake rate (r=-0.76,P=0.02).Conclusions AGI classification can be used to estimate the gastrointestinal function of patients with critical illness,and it has a significant correlation with early EN support.An early goal achieving intervention based on the AGI classification can improve the nutritional status and the general state of the patients.

Objective To investigate the correlation between Bispectral index (BIS) value and the prognosis of patients with coma in ICU.Methods A total of 208 patients with coma in ICU were divided into 4 groups according to the BIS value.In group I,BIS value was 0 to 20; groupⅡ,BIS value 21 to 40; group Ⅲ,BIS value 41 to 60; and group Ⅳ,BIS value greater than 60.Comparison of the difference in BIS value with the differences in prognosis of patients with coma was carried out between four groups,and the prognosis of patients with coma was stratified into consciousness,coma,vegetative state,and brain death.Subsequently,the best cutoff score of BIS value calculated for determining the correlation between BIS and mental state was proposed.Results There are no significant differences in the age and APACHE Ⅱ scores between four groups (P ＞ 0.05).It was inverse correlation between BIS value and mental state (r =-0.749,P =0.00).According to the ROC curve,as BIS value was greater than 42.5,there were higher sensitivity and specificity in Conscious-Coma patients.Conclusions BIS value is correlated with the prognosis of patients with coma in ICU,and BIS value can be a useful marker for estimating the prognosis of comatose patients.

Objective To observe the influence of Xuebijing injection on apoptosis, apoptotic related gene mRNA levels and activity of caspase3 in activated T lymphocyte. Methods The T lymphocytes were obtained from the spleens of BALB/c mice and be induced to be activated and apoptotic by cultured with Con A + IL-2. Apoptosis was investigated by flow cytometry. RT-PCR was used to detect the expression of Fas, FasL, Bcl-2, Bax, IL-2 mRNA, and the activity of caspase3 in T lymphocyte was also detected by spectrophotometric method. In the mean time, the effect of Xuebijing injection on those parameters was observed. Results After the induction, T lymphocyte apoptosis raised at 18 h. At 6 h after the induction, there was no expression of FasL, Bax mRNA, and no change in the expression of Fas and Bcl-2 mRNA. At 18 h, the expressions of Fas, FasL, Bax mRNA rised and the expression of Bcl-2 mRNA lessened. The activity of caspase3 also ascended. Xuebijing injection can cut down the apoptosis induced by induction, make the expression of Fas, FasL, Bax mRNA decreased and Bcl-2 mRNA improved. The activity of caspase3 also fallen after the Xuebijing injection treated. It can promote the expressions of IL-2 mRNA at early phase of AICD (6 h) and depress the expressions at the late period (18 h). Conclusion The apoptosis of T lymphocyte induced by activation was regulated by the change of Fas, FasL, Bcl-2, Bax mRNA expression. Xuebijing injection can ameliorate the apoptosis through regulating the expression of IL-2 and apoptotic related gene mRNA, improve the proliferation activity of T lymphocyte.

OBJECTIVE To comprehend the main pathogens and their drug resistance of multiple organ dysfunction syndrome(MODS) patients in ICU.METHODS We retrospectively analyzed all the bacteria isolated from 40 MODS patients in ICU.RESULTS The number of bacteria strains isolated was 173,92 G-bacteria strains made up 53.18%,60 G+ bacteria strains made up 34.68%,and 21 fungi strains made up 12.14%.The top six were Staphylococcus aureus(23.70%,MRSA was 13.87%),Pseudomonas aeruginosa(14.45%),Acinetobacter baumannii(11.56%),Stenotrophomonas maltophilia(8.67%),Candida tropicalis(8.09%),and Enterococcus faecalis(7.51%).The susceptive rate of S.aureus and Enterococcus to vancomycin was all 100%,the susceptive rate of A.baumannii and Klebsiella pneumoniae to carbapenems was high.64% patients had the multiplicity of infection(MOI) which always linked with long period in ICU,respiratory failure and mechanical ventilation.CONCLUSIONS MODS patients have a high morbility of G+ bacteria,fungi and MOI,most pathogens show multi-resistance to commonly used antibiotics.Strengthening the monitoring of infection and reasonable using antibiotics should be taken.

Objective To evaluate the clinical effect of itraconazole oral solutions on pulmonary candidiasis albicans in ICU patients.Methods A total of 71 patients with candida ablicans in their sputum clutures were randomized into two groups.The itraconazole group(n= 36)received itraconazole 200 mg,p.o.(including nasal feeding),q12h for 14 days.The fluconazole group(n=35)received fluconazole 400 mg for the first dose,then 200 mg,i.v.drip,qd for 14 days.Results There were 31 patients in the itraconazole group and 29 paitents in the fluconazole group who completed their treatment.In the itraconazole and fluconazole group,the clearance of candida ablicans was 64.52%(20/31)vs.65.55%(19/29),cleaning time(10.12?2.57)vs(8.87?1.95)days,effective rate 58.06%(18/31)vs 62.07%(18/29),recovery rate is 19.35%(6/31)vs 17.24%(5/29),occurrence of hepatic dysfunction is 25.81%(8/31)vs 24.14%(7/29),and withdrawal for inefficacy was 3.23%(1/31)vs 6.90%(2/29),respectively.These parameters did not have statistical significance.Conclusion Itraconazole oral solutions can be used effectively and safely in the treatment of pulmonary candidiasis albicans in ICU.Patients with renal dysfunction do not need to adjust the dosage.
