ABSTRACT
Objective:The characteristics of bacteriology and the change of drug resistance in PICU of our hospital during recent 5 years were analyzed to guide clinical rational drug use.Methods:All positive results of bacterial culture in PICU from January 2016 to December 2020 were retrospectively analyzed, and were classified according to the sample source, strain type and drug sensitivity results.The bacterial etiology spectrum and drug resistance in PICU were summarized.Results:A total of 800 pathogenic bacteria were isolated from the specimens collected from the PICU from January 2016 to December 2020, including 476 Gram-negative bacteria, 292 Gram-positive bacteria, and 32 fungi, accounting for 59.50%, 36.50%, and 4.00%, respectively.The top 9 bacteria were: Staphylococcus aureus 134(16.75%), Haemophilusinfluenzae 79(9.88%), Klebsiellapneumoniae 78(9.75%), Streptococcus pneumoniae 74(9.25%), Escherichia coli 56(7.00%), Acinetobacterbaumannii 51(6.38%), Moraxella catarrhalis 48(6.00%), Enterobacter cloacae 26(3.25%), Pseudomonas aeruginosa 25(3.13%). Drug sensitivity results showed that 27(48.21%, 27/56)strains of EScherichia coli and 42(53.85%, 42/78) strains of Klebsiella pneumoniae were positive for ultrawide spectrum β-lactamase, and a total of 24(17.91%, 24/134)strains of methicillin-resistant Staphylococcus aureus were detected.Staphylococcus aureus was almost 100% resistant to penicillin G and ampicillin, and had high resistance rates to clindamycin and erythromycin(72.70% and 72.30%, respectively). It was 100% sensitive to minocycline, teicoranin, vancomycin, linezolid, and dattomycin.The drug resistance rates of Streptococcus pneumoniae to erythromycin and clindamycin were 98.60% and 98.50%, respectively.The drug resistance rates to azithromycin were 96.80%, the drug resistance rates to penicillin G, cefotaxime and ceftriaxone were 12.30%, 5.40% and 1.50%, respectively, and the drug resistance rates to moxifloxacin, linezolid and vancomycin were 100% sensitive.Conclusion:During the past five years, the etiology of the PICU in our hospital is mainly Gram-negative bacteria, and the most common pathogenic bacteria is Staphylococcus aureus.Klebsiella pneumoniae and Escherichia coli infections remain a great challenge.Bacterial resistance moitoring should be strengthened to provide evidence for the rational use of antibiotics.
ABSTRACT
Objective:To explore the effect of different blood sodium levels on the condition and prognosis of patients with severe craniocerebral injury.Methods:A retrospective cohort study was conducted on 150 cases of severe craniocerebral injury admitted to Zhangye People′s Hospital Affiliated to Hexi University from January 2020 to October 2022. According to the five blood sodium values measured on the first day after admission and during the peak period of brain edema (2-4 days after injury) and 7 days after injury, 102 cases of blood sodium metabolic disorder, 43 cases of low sodium group: average blood sodium value<135 mmol/L, 59 cases of high sodium group: average blood sodium value>145 mmol/L. The characteristics of sodium ion metabolism imbalance and the relationship between serum sodium level and Glasgow coma score (GCS), Glasgow prognosis score (GOS) and APACHE Ⅱ score at 2 weeks after injury were analyzed. Measurement data with normal distribution were represented as mean±standard deviation ( ± s), and comparison between groups was conducted using the t-test. count data were expressed as cases or percentages(%), and comparison between groups was conducted using the Chi-square test. Results:The imbalance rate of sodium metabolism in the acute phase after injury was 68.00%(102/150), including 57.84%(59/102) of hypernatremia and 42.16%(43/102) of hyponatremia. The imbalance rate of sodium metabolism at 7 days after injury was significantly higher than that immediately after injury. Hypernatremia occurred earlier than hyponatremia and lasted longer than hyponatremia ( P<0.05). There was no correlation between the low sodium group and the scores of GCS ( R=0.523), GOS ( R=0.367), APACHE Ⅱ ( R=-0.453) ( P>0.05), but the scores of GCS ( R=-0.448) and GOS ( R=-0.486) were negatively correlated with the blood sodium level of the high sodium group ( P<0.05), and the high sodium group was positively correlated with the scores of APACHE Ⅱ ( R=0.477, P<0.05). Conclusions:Patients with severe craniocerebral injury are often accompanied by blood sodium disorder. Hyponatremia can be corrected in a short time and has no effect on the patient′s condition and prognosis. However, hypernatremia seriously affects the recovery of consciousness, prognosis and quality of life of the injured.
ABSTRACT
Objective:To investigate the clinical effect of CAG stimulating regimen for refractory adult early T cell precursor acute lymphoblastic leukemia (ETP-ALL) complicated with fusarium infection and the clinical features as well as antifungal strategy of cutaneous fusarium infection.Methods:The diagnosis and treatment of 1 adult patient diagnosed as ETP-ALL complicated with cutaneous fusarium infection in the First Hospital of Jilin University in September 2020 were retrospectively analyzed, and related literatures were reviewed.Results:VICP chemotherapy regimen showed no effectiveness in this patient who was presented with persistent agranulocytosis complicated with cutaneous fusariosis infection. After amphotericin B therapy for infection, he achieved the stable disease and successfully underwent CAG stimulating regimen salvage treatment. The minimal residual disease turned into negative after consolidation chemotherapy based on the myeloid regimen. Finally this patient survived from haploid allogeneic hematopoietic stem cell transplantation after consolidation chemotherapy and fusarium was under the control by using posaconazole as secondary prevention therapy.Conclusions:CAG stimulating regimen can be recommended as reinduction therapy for relapsed/refractory ETP-ALL. Sequential therapy of amphotericin B followed by posaconazole can be a useful antifungal strategy for fusarium infection.
ABSTRACT
Objective To investigate influencing factors of serum small and dense low-density lipoprotein cholesterol (sd LDL-C) levels in patients with chronic diseases in Zhoujiadu community, and to provide a scientific basis for the treatment of sd LDL-C related chronic diseases. Methods A total of 200 patients with common chronic diseases who were admitted to our hospital from November 2017-November 2019 were selected. Basic data including height, weight, past medical history and family history of the patients were collected. Biochemical indicators were measured to understand dietary structure. The influencing factors of serum sd LDL-C were analyzed by multiple stepwise regression. Results The levels of serum sd LDL-C in patients with advanced age, increased BMI, thickened IMT, fatty liver and coronary heart disease were significantly increased (P<0.05). Pearson linear correlation analysis showed that serum sd LDL-C level of patients with chronic diseases was positively correlated with TC, TG, LDL, ALT and AST, and negatively correlated with HDL (P<0.05). Multiple linear regression showed that TG, BMI, IMT, fatty liver, oil heating (frying and frying) and the use of mixed oil were independent risk factors of sd LDL-C level in patients with common chronic diseases, while HDL-C was a protective factor (P<0.05). Conclusion The levels of serum sd LDL-C in patients with common chronic diseases in Zhoujiadu community were correlated with dyslipidemia, BMI, thickening of IMT, fatty liver, oil heating (frying and frying), and use of mixed oil.
ABSTRACT
Objective To investigate the epidemiology of viral encephalitis&meningoencephalitis and its clinical characteristics during influenza epidemics in Taiyuan city (between November 2017 and February 2018). Methods A total of 112 patients of viral encephalitis & meningoencephalitis from Shanxi Provincial People's Hospital between October 2016 to March 2018 were recruited. Patients were divided into influenza season (n=46)and non－influenza season (n=66). The clinical characteristics of 46 patients with viral meningititis in the influenza season (IS group) were compared with those in the control group of 66 cases in the non－influenza season (NI group). The Logistic regression analysis was used to study the difference between the clinical features of the IS group and the NI group. Results The incidence of hospitalized patients with viral meningititis was significantly higher in epidemic season than in the non－epidemic season. The regression analysis demonstrated that in the IS group the adolescents were 3.879 times older than other age groups, and the symptoms of mental disorder were 2.843 times that of the symptoms without mental disorder, and the duration less than 2 weeks was 3.001 times the duration greater than 2 weeks. Conclusion Although the incidence of hospitalization in patients with viral encephalitis&meningoencephalitis is increased during the influenza season, there is no outbreak of viral meningititis. In this influenza season, adolescents are susceptible to the viral encephalitis &meningoencephalitis and more prone to mental disorder. However, the prognosis of the disease is relatively good.
ABSTRACT
OBJECTIVE@#To summarize the clinical characteristics and treatment of type Ⅲ-b congenital intestinal atresia (CIA).@*METHODS@#The clinical data of 12 type Ⅲ-b CIA treated in the Children's Hospital of Zhejiang University School of Medicine from January 2015 to December 2017 were analyzed retrospectively.@*RESULTS@#Of the 12 patients diagnosed as type Ⅲ-b CIA in operation, treatment was refused during operation by their parents in 2 cases. For one child, only the proximal intestine was partly resected in the first operation, dilatation and dysplasia of the duodenum was diagnosed and total duodenum was resected and sutured in the second operation, as the child had postoperative intestinal obstruction. For one child, due to the long distal normal intestine, distal apple-peel like intestine was partly resected without mesenteric reformation. For the rest 8 children total duodenum resection and mesenteric reformation were performed. During the postoperative follow-up, one case was early rejected for further treatment by parents, one case died from complex congenital heart disease, 5 cases had the complication of short bowel syndrome. All 8 survival children received parenteral nutrition support after operation, 5 of whom received parenteral nutrition support for more than 42 days, and they were followed up for 1-3 years after discharge. The short-time efficacy was satisfactory.@*CONCLUSIONS@#For children with type Ⅲ-b CIA, the distal apple-peel like intestine should be preserved as much as possible, the mesenteric reformation should be performed and the proximal dilated bowel should be partly resected and sutured. Postoperative nutritional support and early intestinal rehabilitation contribute to the compensation for rest intestines.

ABSTRACT
Objective:To investigate the prevalence of physical violence against children (PVAC)by parents and to explore possible related factors.Methods:In two primary schools in Liaoning Province,1164 parents of pupils in grade 1 to 6 were surveyed by a self-administered questionnaire anonymously to analyze situation about PVAC and related factors.PVAC was defined as having one or more following parent-to-child behaviors in the past three months:push,or shook a child;pinch,screw,or scratch a child;hit child's buttocks with hand;hit child's hand,foot,arm,leg or back with hand;hit child's buttocks with an object;hit child's face or head with hand;hit elsewhere (not buttocks)with an object;kicked a child with a foot or hit with a fist.Results:Of 1164 parents,53.1% reported that they had minor PVAC (51.0%)or/and severe PVAC (19.8%).Multivariate logistic regres-sion analysis indicated that following factors increased the risk of PVAC:child's male gender (OR =1.49),younger age of children (OR =1.38),poor school performance of children (OR =1.85 ),mother (OR =2.09),parents'childhood physical violence victimization experiences (OR =1.53),parents'supportive or tolerant attitudes towards corporal punishment (OR =3.15),parents'lower awareness of the harmfulness of physical violence against children (OR =2.31),and lower social economic status (OR =1.47).Conclusion:The PVAC by their parents may be com-mon in the present study.Parents'supportive or tolerant attitudes toward corporal punishment and low awareness of the harmfulness of physical violence is the main risk factors of PVAC.
ABSTRACT
Objective To detect the levels of anti-gliadin IgA and anti-gliadin IgG antibodies in the plasma of the patients with schizophrenia, and to investigate the association between schizophrenia and anti-gliadin IgA, IgG bodies in a Chinese Han population, and to clarify the effect of gliadin on the occurrence of schizophrenia.Methods The plasma samples were collected from 428 patients with schizophrenia and 555 cases of normal control subjects in a Chinese Han population.The gliadin antibodies in plasma,including IgA and IgG,were tested using a native anti-gliadin ELISA test kit.The positive rates of plasma anti-gliadin IgA,and anti-gliadin IgG were tested by Chi-square test between the patients with schizophrenia and control subj ects. The differences of the levels of anti-gliadin IgA and anti-gliadin IgG were tested by Mann-Whitney U test between the patients with schizophrenia and control subjects.Results Compared with normal control group,the anti-gliadin IgA level and the positive rate of plasma anti-gliadin IgA in patient group were increased significantly(P0.05).The anti-gliadin IgA levels in the patients with delusion of observation,delusion of being revealed,delusion of persecution, delusion of j ealousy, delusion of grandeur, incoherence of thinking, illogic thought, bizarre behavior,aggressive behavior,hallucination-delusion syndrome,poverty of thought,emotional blunting/apathy and aboulia were higher than that of the normal controls (P<0.05);the anti-gliadin IgG levels in the patients with delusion of being revealed and delusion of grandeur were higher than that of the normal controls (P<0.05 ). Conclusion Gliadin is associated with the onset of schizophrenia in Chinese Han population, and the plasma antibodies of gliadin maybe play an important rale in the onset of schizophrenia.
ABSTRACT
Objective To study the influence of sunscreens with different efficacy on delayed type hypersensitivity (DTH) and their immunoprotective effect in mice.Methods A cohort of mice were randomly divided into 5 groups with 10 mice in each group:group 1 as the positive control without irradiation,group 2 receiving solar-simulated radiation (SSR) only,group 3 receiving SSR and protected by sunscreen l with sun protection factor 15(SPF15)and persistent pigment darkening(PPD)12,group 4 receiving SSR and protected by sunscreen 2 with SPF 50 and PPD 28,and group 5 as the negative contml receiving SSR only.SSR was carried out on the back of mice with the UVA dose being 1.4 J/cm2 and UVB dose being 100 mJ/cm2 for 10 days.After a 5-day irradiation,the groups 1 to 4 were immunized by intraperitoneal injection with 100 μl(107 cells/ml) of Candida albicans suspension.On the 10th day both sides of the posterior foot pad were measured;then the foot pads were injected with additional 50 μl of the Candida albicans suspension.Twenty-four hours after the injection,the thickness of each foot pad was measured,and immunosuppression rate was calculated.Finally,the mice were sacrificed and skin samples were obtained from the back of these mice followed by the examination of CDla, CD80 and CD86 expression by Western blot.Resets The thickness of edema in foot pads was 0.41±0.38 mm,0.21±0.23 mm and 0.30 ± 0.25 mm in group 1,3 and 4,respectively,significantly higher than in group 5 and 2(0.04±0.03 mm,0.14±0.12 mm,respectively,all P0.05).Significant differences were observed in the immunosuppression rate between group 2,3 and 4(73.0%±11.3%,54.1%±6.4%,29.7%±7.5%,respectively,all P0.05).Conclusions The exposure to sub-erythema dose of UV can induce DTH,and sunscreens have an immunoprotective effect in this process.Epidermal Langerhans cells are not essential for UV-induced immunosuppression.
