ObjectiveTo investigate the efficacy of bundle treatment on patients with moderate or severe acute respiratory distress syndrome (ARDS).Methods A multicenter prospective observational study comparing the result of historical treatment strategy and bundle treatment was conducted. According to the new Berlin standard of definition, 73 patients with moderate or severe ARDS due to pulmonary factors, age from 18 to 65 years, admitted to Department of Critical Care Medicine of Taian Central Hospital and Handan Central Hospital were enrolled. Thirty-three patients admitted during September 2012 to May 2014 (prospective observation period) were enrolled as the bundle treatment group. Forty patients with matched disease history admitted from January 2010 to August 2012 were enrolled as the control group. The patients in bundle treatment group received bundle treatment based on the treatment strategy of primary diseases. Bundle treatment included restrictive fluid management, respiratory support, high-dose ambroxol combined with Xuebijing injection, prevention of ventilation associated pneumonia (VAP), individualized sedation plan, installation of continuous blood purification treatment for critical patients. A special team was organized to ensure the successful implementation of all bundle measures. The acute physiology and chronic health evaluationⅡ (APACHEⅡ) score, oxygenation index, duration of mechanical ventilation, the length of intensive care unit (ICU) stay, incidence of VAP, and 28-day mortality 5 days after treatment were compared between two groups.Results There were no significant differences in basic characteristics of patients between the two groups, including gender, age, etiology, severity, etc. (allP> 0.05) with comparability. Compared with the control group, there was no significant difference in APACHEⅡ score 5 days after treatment in bundle treatment group (15.1±2.8 vs. 16.2±3.0,t = 1.618,P = 0.110). Compared with control group, oxygenation index in bundle treatment group was significantly improved [mmHg (1 mmHg = 0.133 kPa): 135.4±34.5 vs. 117.1±34.2,t = -2.273,P = 0.026), the duration of mechanical ventilation was obviously reduced (days: 8.70±2.50 vs. 10.10±2.67,t = 2.308,P = 0.024), incidence of VAP was significantly lower [18.2% (6/33) vs. 32.5% (13/40),χ2 = 5.027,P = 0.025], and 28-day mortality rate was obviously lowered [24.2% (8/33) vs. 37.5% (15/40),χ2 = 4.372,P = 0.037], the length of ICU stay shown no statistical difference (days:10.40±1.94 vs. 11.30±2.34,t = 1.620,P = 0.110).Conclusion Implementation of bundle treatment can significantly shorten the duration of mechanical ventilation, reduce the incidence of VAP, and improve the prognosis of patients.

OBJECTIVE:
To explore the genetic basis for a child with concomitant spinal muscular atrophy (SMA) and Citrin protein deficiency.
METHODS:
The child was subjected to whole exome sequencing by using target sequence capture high-throughput sequencing. Candidate variants were verified by Sanger sequencing. The SMN genes of the patient were also analyzed through multiplex ligation-dependent probe amplification (MLPA).
RESULTS:
The patient was found to carry homozygous deletion of exons 7 and 8 of the SMN1 gene, for which his parents were both carriers. The patient also carried compound heterozygous variants c.1737G>A and IVS16ins3kbof the SLA25A13 gene, in addition with compound heterozygous variants c.948G>A and c.2693T>C of the POLG gene, for which his parents were carriers, too.
CONCLUSION
Variants of the SLC25A13 gene probably underlay the deficiency of Citrin protein, which may lead to neonatal intrahepatic cholestasis (NICCD). The patient also had SMA. The compound heterozygous variants c.948G>A and c.2693T>C of the POLG gene are likely to cause mitochondrial DNA deletion syndrome type 4A, though other types of mitochondrial disease cannot be excluded.

Objective:To observe the effect of customized orthotic insoles on the gait and balance of hemiplegic stroke survivors.Methods:Sixty stroke survivors with gait abnormalities were randomly divided into a group fitted with ankle foot orthoses (AFO) ( n=30) and a group who received customized orthotic insoles ( n=30). All received conventional rehabilitation training for 4 weeks. Before the fitting, as well as 8 hours and 4 weeks afterward, both groups were evaluated using the Tinetti gait scale (TGS), the plantar pressure balance index, the difference in length between their right and left step, step width, the Timed Up and Go test (TUGT), the Fugl-Meyer lower extremity assessment (FMA-LE), the 6-minute walk test (6MWT), a trunk impairment scale (TIS), the Berg Balance Scale (BBS) and the Barthel Index (BI). Results:At 8 hours after the fitting all of the insole group′s measurements were better than those of the AFO group, on average, but the differences were not statistically significant. After 4 weeks the average TGS, balance index barefoot and wearing the orthosis, step length difference, BBS and BI of the insoles group were significantly better than the AFO group′s averages. The other indicators were not significantly different.Conclusions:Customized orthotic insoles are more effective than an AFO in relieving the biomechanical abnormalities in hemiplegic patients′ feet and ankles, and enhancing their balance and gait.

Guided by the development of new medical science proposed by Ministry of Education and the "Education and Training Plan for Excellent Doctors 2.0", shifted from treatment-oriented to whole life-health cycle, we have explored curriculum ideological and political education in metabolic-related curriculum chain. Firstly, we constructed a core teaching team and had the training of curriculum ideological and political education. The top-level design was made with the integration of moral education into medical education. Secondly, the syllabus was comprehensively revised, containing the connotation of "morality education". The elements relevant to curriculum ideological and political education hidden behind professional courses were excavated. Finally, the mixed teaching mode of online combining with offline was carried out. Metabolism-related curriculum chain, focused on "metabolism, diabetes, obesity and patient education", formed a progressive link from basic medical science to practice to clinical, strengthening the "prevention, treatment and health care" based "one health" philosophy and giving full play to the implicit curriculum ideological and political education hidden behind professional courses. Our practice shows that the implementation of curriculum ideological and political education in metabolism-related curriculum has been accepted by students, and curriculum ideological and political education has been become part of professional courses. The "gene chimera" mode for curriculum ideological and political education incorporation into professional courses needs to be infiltrated imperceptibly, and the effect will be visualized in the future.

Objective To explore the clinical features, cytogenetic and molecular genetics characteristics of trisomy 12 p in neonates. Method The clinical data were reviewed in a neonate with trisomy 12 p confirmed by routine G-banding chromosome karyotype analysis, high throughput sequencing chromosome copy number variation analysis (CNV) and lymphocyte interphase fluorescence in situ hybridization (FISH) . Results The chromosome karyotype in peripheral blood of the neonate was 47, XX, +mar, and the karyotypes of her parents were normal. CNV detected a regional duplication of 12 p13.33-p11.1 (160001-34860000) with a fragment size of 34.7 Mb. Peripheral blood lymphocyte interphase FISH showed that there were 3 signals in the short arm of chromosome 12 in all interphase nuclei of the neonate, and no chimera existed. It was finally confirmed to be trisomy 12 p. Conclusion The combination of clinical features, peripheral blood karyotype analysis, CNV and FISH techniques can effectively confirm the diaganosis of trisomy 12 p.

The cholinergic anti-inflammatory pathway (CAP) is a neuro-immunomodulatory pathway,in which acetylcholine (ACh) released by the interaction of vagal nerves with α7 nicotinic acetylcholine receptor (α7nAChR),which prevents the synthesis and release of pro-inflammatory cytokines and ultimately regulates the local or systemic inflammatory response in a feedback manner. It has been shown that there are many possible effective treatments for sepsis, including vagus nerve stimulation by physical therapy, drugs such as acetylcholine receptor agonist and ultrasound therapy.

Objective To understand the epidemiological characteristics of scrub typhus disease and to provide a scientific basis for the prevention and control of scrub typhus disease. Methods Descriptive epidemiological methods were used to analyze the population and regional distribution of scrub typhus. Seasonal characteristics were analyzed using concentration method and circular distribution method, and incidence trend was analyzed using joinpoint regression model. Results The annual incidence rate of scrub typhus was 0.95/100 000 from 2010 to 2022. The incidence rate of male was 0.77/100 000, lower than that of female 1.12/100 000 (χ2=18.89, P<0.05). The incidence rate of the 60-74 years old group was 3.38/100,000, and the total number of cases in the age group 45-74 years was 416 (74.95%). Occupational distribution was mainly among farmers, with 448 cases (80.72%). The top three regions with the highest number of reported cases (in order: Donghai County, Ganyu District, and Guannan County) reported a total of 416 cases, accounting for 74.95%. Concentration ratio was M=0.9408, and the incidence of scrub typhus disease was strictly seasonal. Circular distribution results showed a-=-62.3728, S=20.8960. The circular distribution results indicated that the peak day was October 19th, and the peak period was between October 7 to December 19. The average annual percentage change (AAPC) of the incidence rate from 2010 to 2022 was 13.70%, 95% CI (-8.62%~41.48%), and the incidence rate showed an upward trend (t=1.15, P=0.249). Conclusion The incidence of scrub typhus disease is strictly seasonal, and the incidence rate over the years shows an upward trend. It is necessary to strengthen monitoring and take various intervention measures to reduce the risk of scrub typhus disease.
