ABSTRACT

Objective:To investigate the correlation of excessive platelet (Plt) recovery at the first time of achieving morphologic complete remission (CR) after induction chemotherapy with minimal residual disease (MRD) and the clinical features of acute myeloid leukemia (AML).Methods:The clinical data of newly-treated 57 AML patients (except for acute promyelocytic leukemia) who achieved CR after induction chemotherapy in Jinjiang People's Hospital from January 2016 to December 2021 were retrospectively analyzed. A total of 57 newly diagnosed adult AML patients were divided into excessive Plt recovery group (Plt recovery>350×10 9/L) and normal Plt recovery group [Plt recovery: (100-350)×10 9/L] according to the Plt recovery. Meanwhile, the MRD was analyzed by using multiparameter flow cytometry (MFC) in patients achieving CR after receiving 1 course of standard treatment regimen or 1-2 courses of demethylation drugs combined with pre-conditioning regimen. The clinical features and negative rate of MRD between the two groups were compared. Results:Among 57 CR patients, 31 (54.4%) patients had CR with excessive Plt recovery and MFC-MRD negative rate was 67.7% (21/31); 26 (45.6%) had CR with normal Plt recovery and MFC-MRD negative rate was 38.5% (10/26); and the difference in the proportion of MRD negative patients between the both groups was statistically significant ( χ2 = 4.89, P = 0.027). There were no statistically differences in the proportions of patients with different gender, age, WBC at initial diagnosis, Plt, chemotherapy regimen and risk degree classification between the two groups (all P > 0.05). Conclusions:In AML patients, excessive Plt recovery at the first time of achieving morphologic CR after induction chemotherapy is associated with negative MRD, which has a certain value in the judgement of therapeutic effect.

ABSTRACT

Objective To explore the application effect and nursing methods of pulse indicator continuous cardiac output (PICCO) monitoring technology in large area burn patients. Methods A total of 82 cases of large area burn patients in the hospital from January 2014 to June 2017 were chosen and divided into experimental group (41 cases) and control group (41 cases) by random digits table method. Two groups of patients were treated with the same method, the control group using routine monitoring method to guide liquid resuscitation, the experimental group based on the use of PICCO monitoring technology to guide fluid resuscitation. Hemodynamic indexes, fluid resuscitation time, ICU days, complication rate and mortality rate of the two groups were compared and analyzed. Results After fluid resuscitation, the acute physiology and chronic health system II (APACHE II) score, heart rate (HR), mean arterial pressure (MAP) and central venous pressure (CVP) of the observation group were (18.4 ± 4.2) marks, (98.7±8.5) once/min, (88.5±9.6) mmHg (1 mmHg=0.133 kPa), (10.3±2.5) mmHg.The APACHE II score, HR, MAP and CVP of the control group were (22.7±5.4) marks, (112.5±9.6) once/min, (81.2±10.5) mmHg, (7.9±2.2) mmHg. There were significant differences between the two groups (t=3.285-6.891, all P <0.05). The cardiac index (CI),cardiac output(CO), global end-diastolic volume index (GEDVI), intrathoracic blood volume index(ITBVI), extravascular pulmonary water index(EVLWI) of the observation group after fluid resuscitation were (4.21±0.46) L·min-1·m-2, (4.87±0.52) L/min, (734.51±95.83) ml/m2, (725.91 ± 88.42) ml/m2, (6.26 ± 1.21) ml/kg, respectively. The difference was statistically significant compared to those before fluid resuscitation (t=10.454-21.143, all P <0.05).Resuscitation time and ICU days in the observation group were (3.1±1.2), (31.4±5.8) d. Resuscitation time and ICU days in the control group were (3.9 ± 1.5), (37.8 ± 6.5) d. There were significant differences between the two groups (t=2.667, 4.704, P<0.05). Conclusions PICCO monitoring plays an important role in the early fluid resuscitation in the treatment of large area burn patients, and strengthening the nursing work is beneficial to the targeted treatment and rehabilitation of the patients.

ABSTRACT

Objective To investigate the intervention effect of Xuebijing Injection on the differentiation of bone marrow hematopoietic stem cells (HSC) in septic mice. Methods Fifty-four male C57BL/6N mice were randomly divided into three groups: normal control group, model group and Xuebijing group, each group with 18 mice. The mouse models of sepsis were duplicated by intra-peritoneal injection of 10 mg/kg E. coli lipopolysaccharide (LPS) method. Starting from the day of modeling, Xuebijing Injection 20 mL/kg was intravenously injected into the tail vein in Xuebijing group, once a day for consecutive 4 days; the normal control and model groups were intravenously injected with normal saline at the same dose and site for 4 days. The bone marrow cells of the femur and tibia of the mice were isolated after 4 days of various treatments in the three groups, and the proportions of bone marrow HSC Lin-Sca-1+c-Kit+ (LSK) and hematopoietic progenitor cells Lin-Sca-1-c-Kit+ (LS-K) of each group were detected by flow cytometry. Results Finally, 14 mice were included in the normal control group, 17 in the model group, and 12 in the Xuebijing group. With the prolongation of time, the body weight of the normal control group gradually increased, the body masses of the model group and the Xuebijing group were decreased first and then increased, reaching a peak at 96 hours after the model was established, but they were still significantly lower than the body mass of normal control group (g: 19.81±0.27, 19.58±0.39 vs. 22.23±0.30, both P < 0.05). Compared with the normal control group, the proportions of LSK, LS-K, long-term HSC (LT-HSC), and megakaryocyte-erythroid progenitor cells (MEP) were all significantly increased in the model group [LSK: (16.62±1.28)% vs. (12.89±0.83)%, LS-K: (44.77±1.77)% vs. (30.34±0.90)%, LT-HSC: (6.88±0.48)% vs. (1.83±0.24)%, MEP: (13.89±1.26)% vs. (9.38±0.66)%, all P < 0.05], the proportion of multipotential progenitor cells (MPP) was significantly decreased [(2.41±0.34)% vs. (5.99±0.59)%, P < 0.05]. Compared with the model group, the LSK and myeloid progenitor (CMP) of the Xuebijing group were significantly reduced [LSK: (12.25±0.69)% vs. (16.62±1.28)%, CMP :(0.31±0.05)% vs. (0.55±0.13)%, both P < 0.05], and LS-K, LT-HSC, MEP showed a decreasing trend [LS-K: (42.75±2.48)% vs. (44.77±1.77)%, LT-HSC:(5.98±0.70)% vs. (6.88±0.48)%, MEP: (10.94±1.36)% vs. (13.89±1.26) %], but the differences were not statistically significant (all P > 0.05). There were no significant differences in the proportions of short-term HSC (ST-HSC) and granulocyte-macrophage progenitor cells (GMP) among the three septic groups (all P > 0.05). Conclusion Xuebijing Injection can improve the differentiation function of bone marrow cells in septic mice, which may be possibly related to the inhibition of pathological proliferation of bone marrow hematopoietic stem cells and progenitor cells in septic mice by Xuebijing Injection.

ABSTRACT

Objective To investigate the prevalence of infantile eczema in Uygur and Han nationalities and the relationship between pregnancy factors and 0-6 months infant eczema, so as to provide a scientific basis for formulating preventive strategies. Methods From January-August 2016 in the Xinjiang Autonomous Region People's Hospital of obstetric and follow-up to fill out the questionnaire in 570 pregnant women and their babies as the research object to establish the baseline survey cohort, pregnancy related information to pregnant women, and 6 months (January, March, on maternal June) follow-up, observe the occurrence of infantile eczema a total of 502, successful follow-up to maternal and child. Using nested case-control study, the cohort occurred in 182 cases of infant eczema as case group, will be in the queue without eczema in 320 infants as control group, using multivariate logistic regression analysis of risk factors during pregnancy baby eczema. Results 0-6 months infant eczema incidence rate was 36.25%, the incidence of Uygur infant eczema (20.43%) was significantly lower than that of Han nationality infant eczema incidence (50.19%) (OR=0.45,95%CI:0.35-0.69) P<0.01). Social and economic factors affecting the occurrence of infantile eczema comparison results showed that the ethnic factors and infant eczema, and more prone to eczema than that of Uygur nationality; and Uygur compared mothers influence allergic history of Han infantile eczema more (χ2=7.09, P=0.008). Multivariate logistic regression analysis showed that the mother has a history of atopy (OR=7.17,95%CI:4.15-12.37), mother′s education level (OR=1.91,95%CI:1.51-2.74), the higher the monthly income (OR=2.68,95%CI:2.17-3.33), maternal smoking during pregnancy (secondhand smoke) (OR=2.42,95%CI:1.96-2.97), frequently eating spicy spicy foods during pregnancy (OR=1.94,95%CI: 1.41-2.68) will increase the risk of infant eczema Supplementation of probiotics (OR=0.13,95%CI:0.07-0.25) and vitamin D (OR=0.13,95%CI:0.06-0.26) during pregnancy is a protective factor in the development of infantile eczema. Conclusions Compared to Uygur, Han Chinese infants are more likely occur eczema, and family history of allergies, education, economic income, pregnancy dietand smoking are risk factors for infant eczema. The same risk factors among Uygur and Han ethnic ,but it had a different results. Compared to Han, Uygur pregnant women eating spicy food caused the risk of infant eczema occurrence is higher, but the short period of housing renovation caused the risk of infant eczema occurrence is lower. Therefore, it is necessary to strengthen nutrition andmonitor living environment during pregnancy. Avoiding to eat spicy food and supplying probiotics and vitamin D, it can prevent or reduce the occurrence of infantile eczema.

ABSTRACT

AIM:To investigate the molecular mechanism of Xijiao Dihuang decoction combined with Yinqiao powder (XDY) in treating viral pneumonia, and the effects of XDY on TNF-α-induced permeability in pulmonary microvascular endothelial cells (PMVEC) and the role of PKC-SSeCKS pathway involved.METHODS:The electric conductivity method was used to detect transendothelial electrical resistance (TER) of primarily cultured PMVEC on Transwell chamber at different time points to determine the permeability of PMVEC.After pretreatment for 24 h, the activity of PKC, TER, and the expression of SSeCKS at mRNA and protein levels were detected.Laser scanning confocal microscopy was used to observe the location of SSeCKS and construction of F-actin in PMVEC.RESULTS:The permeability of PMVECs induced by TNF-α reached the peak at 24 h.Compared with control group, the TER in TNF-α group was decreased, and the activity of PKC was increased.Compared with TNF-α group, the activity of PKC in TNF-α with PKC inhibitor group and TNF-α with XDY group was decreased, while the TER was increased, without difference from control group.Compared with control group, the mRNA expression of SSeCKS and phospho-SSeCKS was increased in PMVEC of TNF-α group, but decreased in TNF-α with XDY group compared with TNF-α group.In control group, F-actin was mainly located around the nucleus and at cytoplasmic borders of PMVEC, forming the dense peripheral bundle, and SSeCKS was evenly scattered in the cell.In TNF-α group, the dense peripheral bundle of F-actin surrounding the cells almost disappeared, and SSeCKS was concentrated around the nucleus.Compared with TNF-α group, the distribution and the structure of F-actin and SSeCKS nearly returned to normal in TNF-α with XDY group.CONCLUSION:XDY inhibits the activation of PKC signaling pathway in PMVEC caused by TNF-α to reduce the mRNA expression of SSeCKS and the phosphorylation of SSeCKS, thus preventing the deformation of endothelial cells and reducing the permeability of PMVEC.

ABSTRACT

Objective:To investigate the value of amino acid metabolomics in evaluating chemotherapeutic response of patients with ad-vanced breast cancer, the changes in the levels of 32 amino acids in the circulating serum of patients before (baseline) and after the first cycle (prognosis) of chemotherapy were tested. Methods:Seventy-three advanced breast cancer patients with local recurrence and distant metastasis admitted at the Liaoning Cancer Hospital from March 2015 to October 2016 were enrolled. Peripheral blood samples (2 mL) were collected before and after the first cycles of chemotherapy from each patient. Thirty-two amino acids in the se-rum were tested using the ultra-performance liquid chromatography-tandem mass spectrometry (LC-MS/MS). Patients were catego-rized into the improvement or deterioration groups, based on the first imaging test after 2-4 cycles of chemotherapy. The changes in amino acids levels were analyzed in different prognosis groups. Results:The levels of the 32 amino acids ranged 3-180000 pmol/L. Compared to their baseline levels, both glycine and L-glutamine increased in the improvement group, but decreased in the deteriora-tion group. Sarcosine was significantly reduced in the improvement group, while differences in its levels were not obvious in the deteri-oration group. L-threonine, taurine, iminodiacetic acid, and L-glutamic acid were increased in both groups. Conclusion:Changes in the serum levels of glycine, sarcosine, and the other amino acids before and after the first cycles of chemotherapy can predict chemothera-peutic response in patients with advanced breast cancer. Amino acid metabolomics may become a potential biomarker for predicting the efficacy of chemotherapy earlier than that of imaging tests, and thereby help improve therapeutic strategies for advanced breast cancer.

ABSTRACT

Objective To explore the effect of early maternal intervention and provide clinical suggestions for the prevention and treatment of infantile eczema. Methods A total of 340 pregnant woman who were receiving prenatal examine and giving birth to their children from January to June 2016 in People's Hospital of Xinjiang Uygur Autonomous Region were selected in this study. The pregnant woman were divided into two groups--control group and observation group by the random number table method.Each group had 170 history cases.The control group was given regularly health guidance,and the observation group was added early intervention such as translate the latest information on the modern social media to them,and giving suggestions of diet and nutrition of infants and living environment.The proportion of risk factors--the each group of infants' genetic history of allergies, birth of ways,feeding pattern and the kind of environmental of which they exposure and so on were analyzed,then the incidence of eczema, the recurrence rate of eczema, the treatment effects and duration of eczema were contrasted.Results After 6 months of prospective follow-up, the observation group of cesarean section and exposing to smoking environmental proportion was respectively 48.82%(83/170),19.41%(33/170), was lower than that of control group 64.71%(110/170),42.35%(72/170),the difference between 2 groups was statistically significant (χ2=8.736, 20.958, P<0.01). The proportion of 4- 6 months of exclusive breastfeeding and correctly adding supplement food respectively 52.35%(89/170),78.24%(133/170),was higher than that in the control group 42.94%(73/170),58.82%(100/170),the difference between 2 groups was statistically significant (χ2=3.418,14.851, P<0.01). After 6 months of prospective follow-up, the incidence and recurrence rate of infants eczema respectively in observation group was 25.88%(44/170), 22.73%(10/170),was lower than that in control group 49.41%(84/170),42.86%(36/170),the difference between 2 groups was statistically significant (χ2=20.047, 5.082, P<0.05).The treatment effect in observation group was superior to the control group.The last,the period of eczema was shorter than that of control group. All of them had statistical meaning(Z=8.876, 10.195,all P<0.05). Conclusions Early interventions can reduce the proportion of high-risk factors that could induce infant eczema, such as cesarean section,exposure to smoking,environmental and other factors.In order to reduce the incidence of infants eczema, improve family′s compliance, reduce eczema attack, improve symptoms, reduce the burden on the family to a great extent,to ensure the normal growth and development of infants,cut off the"allergy process"to prevent distal disease such as allergic asthma,allergic rhinitis etc.

ABSTRACT

Objective: To explore the effects of Qingshi Cream, a compound traditional Chinese herbal medicine, on chronic dermatitis-eczema in mice induced by 2,4-dinitrochlorobenzene (DNCB). Methods: Thirty BALB/C mice were randomly divided into vaseline group, 0.1% mometasone furoate cream group and Qingshi Cream group. Right ears of BALB/C mice were repeatedly challenged with 0.1% DNCB every three days for five times and previously sensitized with 7% DNCB to induce chronic dermatitis-eczema. Mice in different groups were applied Qingshi Cream, 0.1% mometasone furoate cream and vaseline respectively after each challenge. Weight difference of two ears, pathological change of right ear and dermal inflammatory cell number were used to assess the effects of the drugs. Results: After the 5th challenge, weight differences of two ears in the 0.1% mometasone furoate cream group and the Qingshi Cream group were significantly decreased as compared with that in the vaseline group. Changes such as ear swelling thickening and cellular infiltration in dermis were observed, and these features seemed to be more significant in the vaseline group as compared with the 0.1% mometasone furoate cream group and the Qingshi Cream group. Conclusion: Qingshi Cream has an obvious effect in treatment of chronic dermatitis-eczema in mice.
