Objective To investigate the effects of Xuebijing injectio (Chinese herb preparation) on intestinal function and inflammatory responses in severe burn patients. Method Thirty-two patients with comparable severity in burn injury were randomly divided into Xuebijing injectio treatment group (n = 16) and control group (n = 16). Patients in both groups received routine burn therapy, while those in Xuebijing treatment group additionally received Xuebijing injectio 100mL in intravenous drip twice a day for 7 days. Before the treatment and on the 3rd and the 7th day after the treatment, blood concentrations of diamine oxidase (DAO), lipopolysaccharide (LPS) ,tumor necrosis factor-α(TNF-α) and interleukin-6 (IL-6) were determined in both groups. Analysis was made by SPSS 12.0 software. Results The plasma levels of DAO, LPS, TNF-α and IL-6 were decreased in both groups after the treatment. However, the plasma levels of DAO, LPS, TNF-α and IL-6 in the Xuebijing treatment group were significantly lower than those in control group on the 3rd and 7th day after the treatment (P＜ 0.05).Conclusions Xuebijing injectio could protect intestinal function, decrease the plasma level of endotoxin and lessen zhe inflammatory responses in severe burn patients.

OBJECTIVETo investigate the roles of microfilaments in the expression of collagenase and TIMP-1 in normal and hypertrophic scar.

METHODSCell culture and Northern blot hybridization methods were used in this study.

RESULTSAfter the disruption of microfilaments with cytochalasin B, mRNA contents of collagenase and TIMP-1 both increased significantly in normal and hypertrophic scar fibroblasts.

CONCLUSIONThe result suggest that the microfilament cytoskeleton may regulate the synthesis and degradation of ECM, which may be a mechanism of gene regulation during wound healing.

Background:Antibiotics can reduce the efficacy of immunotherapy for melanoma,non-small cell lung cancer and renal cell carcinoma by altering the intestinal microbiome,but their effect in the treatment of gastrointestinal cancer is unclear.Aims:To investigate the prognostic effect of antibiotics on PD-1/PD-L1 inhibitors in the treatment of colorectal cancer(CRC)patients.Methods:The clinicopathological data of 95 patients diagnosed with CRC and treated with immune checkpoint inhibitors(ICIs)from December 2018 to May 2022 at Renmin Hospital of Wuhan University were retrospectively analyzed,and the patients were divided into antibiotic group and control group according to whether antibiotics were used.Risk factors of progression free survival(PFS)and overall survival(OS)were analyzed by univariate and multivariate analysis.Results:Among the 95 patients with CRC,64 were male and 31 were female.The mean age was(60.46±11.82)years.PFS(10.9 months vs.24.8 months,P=0.032)and OS(14.5 months vs.35.5 months,P=0.008)were significantly decreased in antibiotic group than in control group,and one-year survival rate was 56.5%and 78.7%,respectively.Multivariate analysis showed that tumor location and antibiotic use were independent risk factors of PFS(P<0.05),while tumor location,antibiotic use and no radical surgery were independent risk factors of OS(P<0.05).Univariate and multivariate analyses showed that antibiotic administration route,dose were not risk factors of PFS(P>0.05);univariate analysis showed that antibiotic administration route was correlated with OS(P=0.045),however,multivariate analysis showed that antibiotic administration route,infection location were not risk factors of OS(P>0.05).Conclusions:Tumors located in colon and antibiotics applied within 30 days before and after the first dose of ICIs can shorten PFS and OS in CRC patients,while radical surgery can prolong the OS of CRC patients.

Objective To analyze clinical characteristics of severe community-acquired pneumonia during pregnancy and its outcomes, and to explore the relevant risk factors. Methods From September 2012 to September 2017,324 398 pregnancies admitted in 7 tertiary hospitals were included. Clinical data of 33 cases of pregnancies with severe community-acquired pneumonia(severe pneumonia group)and 214 cases of pregnancies with common community-acquired pneumonia (control group) were reviewed retrospectively, including the clinical information, manifestations, laboratory examinations and pregnancy outcomes. Relevant risk factors were analyzed by multivariate logistic regression analysis. Results (1) General data: pregnancies with severe community-acquired pneumonia accounted for 0.010%(33/324 398) of hospitalized pregnancies, the gestational age of two groups were(28±8)and(23±8)weeks, body mass index were(21.7±2.1)and(25.5±3.4)kg/m2, rate of low income were 54.5%(18/33)and 31.8%(68/214), respectively. The differences between two groups were all statistically significant(all P<0.05). No significant differences were found in age, pregnancy and parity times, rate of main pregnant complications such as diabetes and hypertension, educational level, asthma and onset seasons between two groups(all P>0.05). (2)Clinical data: the severe pneumonia group had significantly higher incidence of fever [100.0%(33/33)vs 75.2%(161/214)], shortness of breath(90.9% vs 16.8%)compared with the control group(all P<0.05).The median peripheral leukocytes counts were 12.3×109/L and 10.2×109/L, the hemoglobin level were(84±18) and(107±14)g/L,the albumin level were(26±4)and(37±3)g/L, the median serum urea nitrogen level were 3.7 and 2.4 mmol/L,the serum creatinine level were(72±25)and(45±11)μmol/L, respectively in two groups. The differences were all statistically significant (all P<0.05). No significantly statistical differences were found in coagulation indicator and cardiac function between two groups(all P>0.05).(3) Treatments: in severe pneumonia group, 12 patients(36.4%,12/33)needed invasive mechanical ventilation, 9 patients(27.3%,9/33)needed non-invasive mechanical ventilation, average time of mechanical ventilation was(7±4)days;8 patients(24.2%,8/33)with septic shock needed vasoactive drugs. However, there was no patient in control group needing mechanical ventilation and vasoactive drugs.(4)Pregnant outcomes: one patient(3.0%,1/33)died in the severe pneumonia group, while no death occurred in the control group. The hospital stay between two groups were(15.1±4.1)and(7.0±1.9)days, the rates of abortion and stillbirth between two groups were 42.4%(14/33)and 3.3%(7/214), the rates of premature were 10/19 and 6.3% (13/207), the rates of cesarean were 15/19 and 43.0%(89/207), the rates of low birth weight newborn were 17/19 and 14.0%(29/207), the rates of infected newborn were 15/19 and 10.1%(21/207), the birth weights were(2 165±681)and(3 102±400)g, respectively. The differences between two groups were all statistically significant(all P<0.05).(5)Multivariate logistic regression analysis demonstrated that anemia, low body mass index, hypoproteinemia were risk factors for severe pneumonia in pregnancy(all P<0.05). Conclusions Pregnancy with severe community-acquired pneumonia may be complicated by multiple organ dysfunctions, lead to adverse outcomes. Anemia, malnutrition are risk factors for pregnancy with severe pneumonia. Active and effective treatment may improve its prognosis.
