OBJECTIVE To analyze the pathogens of severe pneumonia induced by different underlying diseases in(hospital) and to evaluate the difference of the pathogens to antimicrobial susceptibility test.METHODS The(bacteria) through sputum culture with VITEK-AMS,and the antimicrobial susceptibility against(bacteria) by K-B method were tested in hospital from 2002 to 2005.RESULTS There were 106 patients with 173 strains of isolated(pathogenic) bacteria,including Klebsiella pneumoniae(KPA) 20.9%,and Escherichia coli(ECO)(16.3%) from the aspiration severe pneumonia;Pseudomonas alcaligenes(PAL) 18.9%,P.aeruginosa(PAL)(16.2%) and Staphylococcus aureus(SAU) 16.2% from the obstructive severe pneumonia;KPN 22.6%,SAU(18.9%),and PAE 17.0% from the COPD complicated with severe pneumonia and PAE 25.0% and SAU 20% from the(hospital-)acquired pneumonia(HAP).CONCLUSIONS The constructed ratio of pathogens is different between(severe) pneumonia infected by different underlying diseases and community-acquired pneumonia without any(underlying) disease.The resistant pathogens are increasing significantly in cases with HAP.

Objective To systematically evaluate the effects of prone position ventilation on newborn with respiratory distress syndrome.Methods We searched databases including PubMed,EMBASE,Cochrane Library,Web of Science,CBM,CNKI,Wanfang and VIP.We included all randomized controlled trials and randomized crossover trials of neonatal respiratory distress syndrome.Studies were selected according to inclusion and exclusion criteria,extracting data and assessing quality.Then RevMan 5.3 software was used to analyze the data.Results Ten studies included seven randomized controlled trials and three randomized crossover trials,and 500 patients were included.The results of meta-analysis showed that in prone position ventilation group SaO2[MD=2.41,95％CI(0.87,3.95),P=0.002],PaO2[MD=5.20,95％CI(3.04,7.36),P＜0.001],Pa2//FiO2[MD=24.40,95％CI(8.35,40.44),P=0.003],the risk of pneumothorax [RR =0.10,95％ CI (0.01,0.76),P=0.03] and intracranial hemorrhage [RR =0.41,95％ CI (0.20,0.83),P=0.01]and duration of mechanical ventilation [MD=-23.22,95％CI(-38.30,-8.14),P=0.003] compared with supine positiongroup had significantly statistical difference;however there was no significant difference in ventilator-associated pneumonia[RR=0.72,95％CI(0.48,1.09),P=0.12] between two groups.Conclusion Prone position ventilation is effective to improve SaO2,PaO2 and PaO2/FiO2,shorten duration of mechanical ventilation and reduce the risk of pneumothorax and intracranial hemorrhage in newborn with respiratory distress syndrome.While it could not effectively reduce incidence of ventilator-associated pneumonia.Due to the limitations of the quality of studies included,multi-centered randomized controlled trials with large sample size are needed in the future to evaluate the effects of prone position ventilation on neonatal respiratory distress syndrome.

Objective Investigate and intervene the psychological health state of clinical trainees in the hospital of Yuxi City, in order to explore the method to improve the psychological health and clinical quality of teaching. Methods From 2009 to 2013, clinical trainees were investigated by SCL-90. Intervention for interns included holding psychological health lectures and making psychological counseling for the serious interns. At the same time, the teachers were trained to carry out two-way intervention between the teachers and clinic interns and to improve clinical interns' psychological health. Results Before the intervention,among 216 interns,34 (15.74%) showed positive. Except fear factor, other factors were significantly different than national norms ( <0.05). After the intervention, among 149 interns, 20 ( 13.42%) showed positive. Obsessive-compulsive symptom, depression,anxiety,hostility, spirit factors and the mean scores were all lower than before ( <0.05),similar to the national norm.Conclusion Clinical trainees have prominent psychological problems. Teaching hospitals should pay more attention to psychological health of them. Intervention is necessary and effective in improving psychological health and quality of teaching.

Objective In order to prevent the infection of Acinetobacter baumannii and use antibiotics rationally,the clinical infection and drug resistant data of multi-drug resistance Acinetobacter baumannii (MRAB)detected in intensive care unit (ICU)of Beijing Friendship Hospital from 2011 to 2013were analyzed.Methods This study is a retrospective study.One hundred and eighty five strains of MRAB were collected from the patients in ICU from January 2011 to December 2013.Identificationand antibiotic susceptibility of strains were determined with Vitek-2 Compact automatic bacteria identification system.The annual infection rate of MRAB was counted.PCR was used to detect the resistance genes.The clinical features of the patients with MRAB were analyzed.The average age,acute physiology and chronic health evaluation (APACHE) Ⅱ score,duration in ICU and mortality ratio of the MRAB patients were compared with the patients without MRAB.Rank-sum test was used to analyze the average age,APACHE Ⅱ score and duration in ICU.Chi-squared test was used to analyze the mortality ratio and annual infection rate.Results The average age [(67 ± 17)vs (59-± 19) years old,Z =-5.365,P =0],APACHE Ⅱ score [(25.68±7.93) vs (17.62±8.39),Z=-14.821,P=0],duration in ICU [(27 ±29) vs (5 ±8) d,Z =-4.342,P =0] and mortality ratio [10.82％ (53/185) vs 28.65％ (147/1 359),x2 =45.92,P =0] of the patients infected by MRAB were significantly higher than those without the infection.The MRAB was found mostly in sputum and bronchial precipitates (83.78％,155/185).Though detection rate reduced yearly and there was a significant reduction in 2013 compared with 2011 [11.07％ (69/469) vs 8.37％ (52/621),x2 =8.755,P =0.003],the drug resistant rate was in high level and did not show any change in the 3 years.OXA-23 and OXA-51 were detected in all MRAB.Conclusions The main drug resistant mechanism of MRAB in ICU is related to OXA-23.More active methods of coutrol and prevention of MRAB should be used in elderly aud severely pneumonic patients.Intensive disinfection and isolation measures can decrease MRAB detection rate.Combined antibiotics should be used in patients with MRAB infection.

Objective:To explore the effect of family integrated care (FIC) combined with intelligent health education platform in health education for elderly patients with stroke.Methods:Eighty patients with stroke were included from the Department of Neurology of the Second Affiliated Hospital of Chongqing Medical University from June 2019 to May 2020. They were divided into the experimental group and the control group ( n=40, respectively) by the random number table method. Patients in the control group received routine FIC in the Department of Neurology. Additional intelligent health education platform was provided for the experimental group to carry out intensive education. The modified Barthel index scale, self-care compliance scale and hospital anxiety and depression scale (HADS) were used before and after the intervention to evaluate patient′s self-care ability, self-care compliance and the degree of anxiety and depression. Results:Finally, 39 patients in the experimental group (1 case lost to followed-up) and 37 patients in the control group (3 cases lost to followed-up) completed the study. After the intervention, the scores of the modified Barthel index and self-care compliance scale of the experimental group were significantly higher than those of the control group [(65.9±12.6) vs (60.1±11.9) points, (78.2±13.6) vs (71.4±14.6) points], the HADS score was significantly lower than the control group [(15.18±2.46) vs (19.46±2.40) points] (all P<0.05). The scores of the modified Barthel index scale and self-care compliance scale of the experimental group after the intervention were significantly higher than those before the intervention [(65.9±12.6) vs (40.8±12.5) points, (78.2±13.6) vs (54.6±15.9) points] (all P<0.05), the HADS score was significantly lower than before the intervention [(15.18±2.46) vs (21.74±3.52) points] (all P<0.05). Similarly,the scores of the modified Barthel index and self-care compliance scale of the control group after the intervention were significantly higher than before the intervention [(60.1±11.9) vs (41.6±9.72) points, (71.4±14.6) vs (54.3±14.8) points], the HADS score was significantly lower than before the intervention [(19.46±2.40) vs (21.38±3.09) points] (all P<0.05). Conclusion:FIC combined with intelligent health education platform can significantly improve the self-care ability and self-nursing compliance of elderly stroke patients, and markedly improve the degree of depression and anxiety.

OBJECTIVETo clinically investigate and identify the occlusal force as one of factors relative to formation of wedge-shaped defects.

METHODS123 subjects, selected from a group of middle-aged and elderly people in an urban area were divided into four groups: control, light, middle and severe group according to the severity of wedge-shaped defects. Cuspid, first and second premolars, and first molar in maxilla were examined for occlusal force by occlusometer, and the peak value of occlusal contact strain on every maxillary tooth was studied by photocclusion.

RESULTSSignificant reduce of occlusive force in the defected teeth was found than that of in the control teeth. The occlusal contact strain of first premolars with defects by photocclusion was statistically increased. The relative occlusal contact strain of first premolars and first molar of defects was higher than that of their proximate teeth.

CONCLUSIONOcclusal force could have relation to the formation of wedge-shaped defects.

OBJECTIVETo investigate the feasibility of using immunohistochemical technique to detect the presence of fetal erythroblasts in the maternal circulation for prenatal diagnosis.

METHODSMaternal blood was obtained from 30 pregnant women at 8 to 26 weeks of gestation. Nucleated red blood cells (NRBCs) were separated with Percoll using a discontinuous density gradient method, and then smeared on microscope slides using cytocentrifugation. Slides were stained with antibody against the gamma-chain of fetal hemoglobin (HbF). All positive NRBCs were collected by micromanipulator under microscopic observation, and then amplified by improved primer extension preamplification(PEP). Sex and Duchenne's musclar dystrophy (DMD) genetic diagnosis were determined from a small aliquot of the PEP reaction.

RESULTSNRBCs stained with HbF were found in all of the blood from the 30 pregnant women at 8 to 26 weeks of gestation. 17 male fetuses and 13 female fetuses were detected in the 30 cases. These results coincided with those of induced labor or amniotic fluid control, and 8 fetuses at the risk of DMD were diagnosed.

CONCLUSIONThis diagnostic method using immunohistochemical technique to mark fetal NRBC shows good application prospects.

OBJECTIVE: To explore the genetic basis for a pedigree affected with Charcot-Marie-Tooth (CMT) disease through high-throughput sequencing. METHODS: Potential variants of the genes associated with CMT were screened by next-generation sequencing (NGS) of the members of the pedigree. RESULTS: NGS has revealed that the two affected sisters both harbored homozygous c.1A>G variant of the GDAP1 gene, which caused replacement of the first amino acid Methionine by Valine (p.Met1Val). Their parents were both carriers of the heterozygous c.1A>G variant. The variant was unreported previously and has an extremely low frequency in the population. Meanwhile, one of the sisters and the mother also carried heterozygous c.710A>T variant of the BAG3 gene. CONCLUSION The homozygous c.1A>G variant of the GDAP1 gene probably underlay the CMT in both children. Above result has enabled clinical diagnosis and genetic counseling for this pedigree.

OBJECTIVETo evaluate the efficacy and safety of fecal microbiota transplantation (FMT) for gastrointestinal disorders.

METHODSRetrospective analysis of the clinical data of 406 patients who underwent FMT from May 2014 to April 2016 in the Intestinal Microenvironment Treatment Centre of Nanjing General Hospital was performed, including patients with constipation(276 cases), recurrent Clostridium Difficile infection (RCDI, 61 cases), ulcerative colitis(44 cases), irritable bowel syndrome (15 cases) and Crohn's disease(10 cases). Donors were completely unrelated, 18- to 50-year-old non-pregnant healthy adult, with healthy lifestyle and habits, without taking antibiotics, probiotics and other probiotics history within 3 months. There were three routes of FMT administration: patients received 6 days of frozen FMT by nasointestinal tube placed in the proximal jejunum under gastroscope (319 cases); patients received capsules FMT per day for 6 consecutive days (46 cases) or once 600 ml of treated fecal liquid infusion into colon and terminal ileum by colonoscopy(41 cases).

RESULTSClinical cure rate and improvement rate of different diseases receiving FMT were respectively as follows: RCDI was 85.2% (52/61) and 95.1%(58/61); constipation was 40.2%(111/276) and 67.4%(186/276); ulcerative colitis was 34.1%(15/44) and 68.2% (30/44); irritable bowel syndrome was 46.7% (7/15) and 73.3% (11/15) and Crohn disease was 30.0%(3/10) and 60.0%(6/10). RCDI had the best efficacy among these diseases(P<0.01). There was no significant difference between the three routes of FMT administration(P=0.829). The clinical cure rate and improvement rate of different routes were 43.3%(138/319) and 58.6% (187/319) respectively in nasogastric transplantation group, 41.5%(17/41) and 61.0%(25/41) in colonoscopy group, 37.0%(17/46) and 63.0% (29/46) in the capsule transplantation group. There was no serious adverse event during the follow-up. The most common side effects were respiratory discomfort (27.3%, 87/319) and increased venting (51.7%, 165/319) in nasogastric transplantation group. Diarrhea was the most common complication in colonoscopy group (36.6%, 15/41). The main symptoms were increased venting (50.0%, 23/46) and nausea(34.8%, 16/46) in oral capsule group. Side effect symptoms disappeared after the withdraw of nasogastric tube, or at the end of treatment, or during hospitalization for 1-3 days.

CONCLUSIONSFMT is effective for many gastrointestinal disorders. No significant adverse event is found, while the associated mechanism should be further explored.
