Objective To observe the effects of Shenqi Fuzheng injection on peripheral blood T lymphocyte subsets, T-cell apoptosis and cytokine in patients with sepsis and approach their significance.Methods Forty patients with sepsis admitted into Department of General Surgery of the General Hospital of Tianjin Medical University were randomly divided into two groups: routine group (20 cases, received routine western medicine treatment) and Shenqi Fuzheng treatment group (20 cases, received routine western medicine treatment and intravenous drip of Shenqi Fuzheng injection 250 mL per day), 7 days as a course of treatment in both groups. On the 1st, 3rd and 7th day after treatment, evaluation of acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) scores was carried out in the two groups. The percentages of peripheral blood T-lymphocyte subsets CD4+, CD8+, CD4+/CD8+ and apoptosis were measured by flow cytometry. Meanwhile, tumor necrosis factor-α (TNF-α), interleukins (IL-6 and IL-10) levels were detected by enzyme linked immunosorbent assay (ELISA).Results APACHE Ⅱ scores of two groups on the 3rd day were apparently decreased in comparison with those on the 1st day after treatment, and this situation persisted until the 7th day after treatment; meanwhile, the decrease in APACHE Ⅱ score in Shenqi Fuzheng treated group was more notable than that in routine group (10.05±3.71 vs. 13.15±4.65,P < 0.05). Along with the prolongation of time, in both groups, the peripheral blood TNF-α and IL-6 levels were gradually decreased; the IL-10 level was gradually increased, until the 7th day it began to decrease. On the 7th day, the TNF-α and IL-6 levels in Shenqi Fuzheng treated group were decreased more significantly than those in routine group [TNF-α (ng/L): 204.6±18.1 vs. 218.9±21.3, IL-6 (ng/L): 3.68±0.30 vs. 3.95±0.49, bothP < 0.05]. There was no significant difference between Shenqi Fuzheng treated group and routine group in the IL-10 level on the 7th day (ng/L: 173.8±23.3 vs. 174.8±18.9,P > 0.05). On the 1st, 3rd and 7th day after treatment, the percentage of CD4+ T cells and CD4+/CD8+ ratio were firstly fallen and then elevated up, the percentage of CD8+ T cells was gradually decreased, and the percentages of CD4+ and CD8+ apoptosis showed a trend of rise up first and then fall in the two groups. On the 7th day after treatment, there were significant differences between Shenqi Fuzheng treated group and routine group in terms of the percentage of CD4+, CD4+/CD8+ ratio and the rate of CD4+ apoptosis [CD4+ T cells: (38.3±4.7)% vs. (35.5±5.5)%, CD4+/CD8+: 1.55±0.29 vs. 1.36±0.27, CD4+ T apoptosis: (11.2±3.8)% vs. (14.1±5.5)%, allP < 0.05]. There were no statistically significant differences between routine group and Shenqi Fuzheng treated group in the percentages of CD8+ T cells and CD8+ apoptosis at each time point (allP > 0.05).Conclusion Shenqi Fuzheng injection can effectively reduce the percentage of CD4+ T cell apoptosis, increase the percentage of CD4+ T cells and CD4+/CD8+ ratio, lower the inflammatory factors, improve the immune function and disease severity in patients with sepsis.

Objective:To screen the ectodysplasin A (EDA)gene mutation in the patients with non-syndromic tooth agenesis and ectodermal dysplasia,and to analyze the phenotype of missing teeth pattern in these two groups of patients.Methods:In the study,174 patients with tooth agenesis (143:non-syn-dromic,31:ectodermal dysplasia)and 451 health control volunteers were enrolled from the clinic,and the genome DNA was extracted from either peripheral blood or oral mucosal swab.The coding region of EDA gene was then amplified by PCR,sequenced and blasted to online NCBI database.The missing teeth were recorded for all patients,and the missing teeth from patients with EDA mutation were com-pared among the different dentition sites.Results:33 patients were identified with EDA mutation.In the non-syndromic patients,13 /143(9.09%)were identified with EDA mutation,while in patients with ec-todermal dysplasia,20 /31 (64.52%)were found with EDA mutation.Ten novel EDA mutations were identified (c.769G >C[p.G257R],c.936C >G[p.I312M],c.223G >A[p.E75K],c.1166C >T[p. P389L],c.133G >C[p.G45R],c.1109G >A[p.E370K],c.914G >T[p.S305I],c.916C >T[p. Q306X],c.602G >T[p.G201V],c.88 -89insG[p.A30GfsX69]).For each dentition site there was no statistic difference in the number of missing teeth between the left and right sides,so the number from both sides were combined later in the analysis.In the patients with EDA mutation,the non-syndromic pa-tients had fewer missing teeth (15.9 ±6.4 missing teeth for each,207 /364 in total)than the patients with ectodermal dysplasia (23.9 ±4.3,478 /560).In the non-syndromic patients with EDA mutation, the maxillay central incisors and first molars were less affected,with the same missing rate as 19.2% (5 /26).While the mandibular central incisors (with a missing rate of 76.9%,20 /26),the maxillary late-ral incisors (the missing rate:88.5%,23 /26 ),the mandibular lateral incisors (the missing rate:80.8%,21 /26),and the maxillary first premolars (the missing rate:80.8%,21 /26)were more likely to be missing.In the ectodermal dysplasia patients with EDA mutation,only maxillary central incisors (the missing rate:60%,24 /40),maxillary canines (the missing rate:70%,28 /40),mandibular ca-nines (the missing rate:67.5%,27 /40),maxillary first molars (the missing rate:65%,26 /40)and mandibular first molars (the missing rate:72.5%,29 /40)had higher possibility of persistence.Teeth at other dentition sites were more likely to be affected (the minimum missing rate:87.5%,35 /40). Conclusion:The findings would help to reveal the EDA gene and its function in ectodermal organogene-sis.

Objective To explore the clinical characteristics and outcomes of obstetric patients in intensive care unit(ICU).Retrospective study over a period of four years and 232 cases were included.Methods Records were reviewed for clinical characteristics,maternal and neonatal outcomes.All patients were divided into obstetric related disease group and non-obstetric related disease group.Results The patients who had regular antienated examination only accounted for 34.5％.Seven patients died.Hypertensive disorders,heart disease and hemorrhage are the main cases of admission.Among the 232 obstetric patients,there are 131 cases(56.5％) in the obstetric group,101 cases(43.5％) in the non-obstetrical group.The average age of the patients in obstetric related disease group were lower than those in non-obstetric related disease group (P ＜ 0.001).The postpartum hemorrahge within 24 hours,the rates of hystereyomy and the rates of hemorrhagic shock in obstetric related disease group were all higher than those in non-obstetric related disease group (P ＜ 0.001).Conclusion The establishment of specialized obstetric ICU and physicians with obstetric and ICU knowledge to manage such patients will be a future development trend.

OBJECTIVE To study the effects of Wubao capsule on airway inflammation in asthmatic model mice by regulating upstream and downstream cytokines of type Ⅱ innate lymphoid cells （ILC2s）. METHODS Totally 40 female BABL/c mice were randomly divided into normal group， model group， positive control group （dexamethasone 1 mg/kg）， Wubao capsule low-dose and high-dose groups （0.5， 1 g/kg）， with 8 mice in each group. Asthma models were induced by ovalbumin （OVA） sensitization and nebulization. Each group was given normal saline or drug intragastrically for 7 consecutive days. The contents of IgE and OVA-IgE in serum， the contents of interleukin 5 （IL-5）， IL-9， IL-13， IL-25， IL-33， thymic stromal lymphopoietin （TSLP） and mucin 5AC （MUC5AC） in bronchoalveolar lavage fluid （BALF） were determined by ELISA. HE staining was used to observe the pathological changes of lung tissues in mice. PAS staining was used to observe the changes of goblet cell proliferation in each group. The number of ILC2s in lung tissue was determined by flow cytometry （except for Wubao capsule low-dose group）. RESULTS Compared with model group， the contents of IgE and OVA-IgE in serum and the contents of IL-5， IL-9， IL-13， IL-25， IL-33， TSLP and MUC5AC in BALF were significantly reduced in Wubao capsule high-dose and low-dose groups （P＜0.01）. The infiltration of inflammatory cells and the thickening of basement membrane in lung tissue was alleviated to varying degrees， and the proliferation of goblet cells was inhibited； the number of ILC2s in lung tissues of mice in Wubao capsule high-dose group was significantly reduced （P＜0.01）. CONCLUSIONS Wubao capsule could effectively reduce the number of ILC2s in lung tissue， the contents of upstream and downstream cytokines of ILC2s in BALF of asthmatic model mice， so as to inhibit the airway inflammation and improve asthma.
