Objective: To investigate the health literacy and its influencing factors among residents in areas out of poverty in Kunming City, so as to provide insights into formulating health education strategies. Methods: A total of 1 916 permanent residents at ages of 15 to 69 years were sampled in three areas out of poverty in Kunming City using the multi-stage stratified random sampling method and probability proportionate to size sampling method from August to October, 2020. Health literacy was investigated using the Questionnaire on the Health Literacy among Chinese Residents, the level of health literacy was analyzed and weighted by the population of the China's Seventh National Population Census. Factors affecting health literacy among residents in areas out of poverty were identified using a multivariable logistic regression model. Results: A total of 1 916 questionnaires were allocated, and 1 908 valid questionnaires were recovered, with an effective recovery rate of 99.58%. The respondents included 997 men (52.25%) and 911 women (47.75%), and had a mean age of (45.58±14.28) years. The level of health literacy was 21.38%. Multivariable logistic regression analysis identified age (15 to 24 years, OR=5.087, 95%CI: 1.573-16.450; 25 to 34 years, OR=6.016, 95%CI: 1.991-18.183; 35 to 44 years, OR=7.526, 95%CI: 2.541-22.289; 45 to 54 years, OR=4.800, 95%CI: 1.640-14.050), educational level (junior high school, OR=5.333, 95%CI: 3.100-9.175; high school/vocational high school/technical secondary school, OR=19.895, 95%CI: 10.418-37.966; college or above, OR=27.580, 95%CI: 12.349-61.597) as factors affecting health literacy among residents in areas out of poverty in Kunming City. Conclusion The level of health literacy is 21.38% among residents in areas out of poverty in Kunming City, and age and educational level are associated factors.

Objective:To evaluate the quality of critical patient handover practice between emergency room and intensive care unit (ICU) nurses, and to provide a basis for structured handover process.Methods:From March to July 2023, a total of 223 pairs of nurses in emergency room and ICU (including EICU) of 5 Class 3 Grade A general hospitals in Suzhou were selected as the research objects by using cross-sectional survey method and convenience sampling method. Self-designed general information questionnaire and Patient Handover Practice Quality Scale were used to investigate the included 223 pairs of nurses in emergency room and ICU on the current situation of handover time and quality.Results:A total of 211 pairs of nurses were included, including 286 females (67.8%) and 136 males (32.2%). The average age of emergency department nurses was (27.31 ± 2.17) years old, and ICU nurses was (26.96 ± 3.04) years old. The total scores of the patient handover practice Quality Scale for nurses in the emergency room and ICU were (45.25 ± 6.26) and (43.55 ± 7.19) points respectively, and the scores of the information transmission dimension were (20.47 ± 5.43) and (17.66 ± 3.45) points. The scores of common understanding dimension were (7.59 ± 2.31) and (8.58 ± 2.46) points. The scores of work atmosphere dimension were (7.93 ± 2.11) and (8.39 ± 2.29) points. The scores of handover situation dimension were (5.33 ± 1.30) and (5.70 ± 1.53) points, and the differences were statistically significant ( t values were - 6.35-4.22, all P<0.05). There were statistically significant differences in the scores of handover practice quality between emergency room nurses and ICU nurses according to specialization, education background, working years and job category ( t values were - 4.91-2.56, all P<0.05). Conclusions:Emergency room nurses and ICU nurses have different requirements and expectations for handover procedures, so it is necessary to build a structured handover practice framework and carry out personalized handover practice training, in order to achieve the consistency of handover content and improve the quality of critical patients handover practice.

Attention deficit hyperactivity disorder is a common neurodevelopmental disorder characterized by persistent attention deficit, hyperactivity, and impulsive behaviors that are not consistent with developmental age.Academic and vocational difficulties, social exclusion, and delinquent behaviors are manifested in daily life.It is also commonly accompanied by psychiatric problems.At the same time, mental problems are common, and the overall quality of life is greatly affected, placing a heavy burden on society as well as the family.International attention deficit hyperactivity disorder experts have developed a common and comprehensive International Classification of Functioning, Disability and Health core set of classifications for assessing individual functioning in attention deficit hyperactivity disorder.

Objective Through factor analysis of the quantified syndrome information of 558 cases of kidney yang deficiency syndrome,the constructing feature of kidney yang deficiency syndrome was revealed,which provides clinical data support for the objectification,standardization and normalization of kidney Yang deficiency syndrome.Methods Firstly,the frequency analysis of symptoms,tongue and pulse signs of 558 patients with kidney Yang deficiency syndrome was carried out,and then the main syndrome information of the patients with kidney Yang deficiency syndrome was quantified.Finally,the common factors and their representative variables of kidney Yang deficiency syndrome were screened out through factor analysis,and the constructing feature of kidney Yang deficiency syndrome was analyzed combined with TCM syndrome knowledge.Results Eight common factors with eigenvalues greater than 1 were extracted by principal component analysis,and the cumulative contribution rate was 60.483%.After the factor rotation,the representative variables with the absolute value of load coefficient greater than 0.45 in each common factor were selected.The representative variables of F1 are afraid of cold and fond of warmth(0.947)and intolerance to cold(0.932).The representative variables of F2 are waist pain(0.754),waist and knee weakness(0.720)and cold in waist and knees(0.466).The representative variables of F3 are depression(0.749),insomnia(0.711)and diarrhoea(0.470).The representative variables of F4 are thin fur(0.819)and white fur(0.768).The representative variable of F5 are tinnitus and deafness(0.687),frequent nocturnal urination(0.591)and decreased libido(0.587).The representative variables of F6 are pulse sinking(0.766)and pulse weakness(0.736).The representative variables of F7 is thready pulse(0.942).The representative variable of F8 is pale tongue(0.961).External syndrome of disease location involved in these common factors are waist,bone,brain,ear,anterior Yin,posterior Yin and reproductive function.The disease nature involved in these common factors is deficiency and cold.Conclusion The basic constituent units of kidney Yang deficiency syndrome include disease location syndrome elements and disease nature syndrome elements.The disease location is kidney,and the abnormal changes of kidney location are mainly external symptoms of waist,bone,brain,ear,anterior Yin,posterior Yin and reproductive function.Its disease nature is deficiency and cold.Yang deficiency leads to external cold.Yang Qi deficiency can not warm the body surface resulting in the appearance of external cold syndrome.

For wild natural medicine, unanticipated biodiversity as species or varieties with similar morphological characteristics and sympatric distribution may co-exist in a single batch of medical materials, which affects the efficacy and safety of clinical medication. DNA barcoding as an effective species identification tool is limited by its low sample throughput nature. In this study, combining DNA mini-barcode, DNA metabarcoding and species delimitation method, a novel biological sources consistency evaluation strategy was proposed, and high level of interspecific and intraspecific variations were observed and validated among 5376 Amynthas samples from 19 sampling points regarded as "Guang Dilong" and 25 batches of proprietary Chinese medicines. Besides Amynthas aspergillum as the authentic source, 8 other Molecular Operational Taxonomic Units (MOTUs) were elucidated. Significantly, even the subgroups within A. aspergillum revealed here differ significantly on chemical compositions and biological activity. Fortunately, this biodiversity could be controlled when the collection was limited to designated areas, as proved by 2796 "decoction pieces" samples. This batch biological identification method should be introduced as a novel concept regarding natural medicine quality control, and to offer guidelines for in-situ conservation and breeding bases construction of wild natural medicine.

Huntington's disease (HD) is an autosomal dominant inherited disease with insidious onset and slow progression, mainly characterized by chorea-like symptom, intelligence decline, and psychiatric abnormalities. Cause of the disease is abnormal expansion of CAG trinucleotide repeat sequences in the first exon of the Huntington gene (HTT) on chromosome 4. Despite the clear etiology, currently, no effective therapeutic measures to control the disease progress is noted, and symptomatic treatment is still the main treatment in clinical practice. This article provides a brief overview of the current clinical trials, clinical challenges, and future development of HD gene therapy to provide references for subsequent related research.

Objective:To explore the long-term effect of endoscopic radiofrequency ablation for the treatment of unresectable ampullary carcinoma.Methods:Clinical data of patients with ampullary carcinoma who received endoscopic radiofrequency ablation in the Third Affiliated Hospital of Naval Medical University from January 2012 to May 2019 were retrospectively collected, including basic information, frequency of radiofrequency ablation, the type of biliary stent, postoperative complications, and follow-up. Kaplan-Meier method was used to analyze the survival of patients after endoscopic radiofrequency ablation. Relationship between frequency of radiofrequency ablation, type of biliary stent and overall survival time was analyzed.Results:A total of 50 patients were enrolled, including 31 males and 19 females, aged 73.0±9.7 years. Twenty-five patients (50.0%) underwent 1 radiofrequency ablation treatment, while 25 patients (50.0%) underwent radiofrequency ablation treatments more than twice. Postoperative complications occurred in 6 patients (12.0%), all of which were mild symptoms. The average follow-up was 22.3 months, with a total of 39 (78.0%) deaths, 5 (10.0%) lost to follow-up, and 6 (12.0%) surviving. The median overall survival time was 16.9 (95% CI: 9.1-24.8) months, with cumulative survival rates of 62.0%, 38.5%, 27.0%, and 12.6% at 1, 2, 3, and 5 years, respectively. The median overall survival time of those treated with radiofrequency ablation ≥2 times showed a trend of prolongation compared to patients treated once, but the difference was not statistically significant [26.7 (95% CI: 9.7-43.7) months VS 12.6 (95% CI: 4.9-20.3) months, χ2=3.049, P=0.081]. Plastic stents were used in 32 patients (64.0%) and metal stents in 18 patients (36.0%). There was no significant difference in median overall survival time between patients using metal and plastic stents [17.1 (95% CI: 6.1-28.0) months VS 15.9 (95% CI: 6.9-24.9) months， χ2=0.029， P=0.865]. Conclusion:Endoscopic radiofrequency ablation is a safe treatment for unresectable ampullary carcinoma, and multiple consecutive treatments may increase the survival benefit.

Objective:To investigate the efficacy of endoscopic stent placement for patients with Bismuth type Ⅳ hilar cholangiocarcinoma.Methods:Data of 229 patients with unresectable Bismuth type Ⅳ hilar cholangiocarcinoma who successfully underwent endoscopic stent placement at the Department of Endoscopy, the Third Affiliated Hospital of Naval Medical University from January 2002 to January 2019 were retrospectively analyzed. Outcomes included clinical success rate, complication incidence, stent patency period and overall survival time. The patency of stents and overall survival time of patients were estimated by using the Kaplan-Meier method. The independent predictors for stent patency and overall survival of patients were analyzed by a multivariate Cox proportional regression model.Results:The overall clinical success rate was 78.2% (179/229). The incidence of early cholangitis after endoscopic retrograde cholangiopancreatography was 20.5% (47/229). The median stent patency and overall survival time were 5.7 (95% CI: 4.8-6.7) months and 5.1 (95% CI: 4.2-6.0) months, respectively. Further multivariate Cox regression analysis showed that metal stent ( P<0.001, HR=0.452, 95% CI: 0.307-0.666) and bilateral stents with bilateral angiography ( P=0.036, HR=0.644, 95% CI: 0.427-0.971) were independent predictors of stent patency; total bilirubin>200 μmol/L ( P=0.001, HR=1.627, 95% CI: 1.208-2.192), metal stent ( P=0.004, HR=0.636, 95% CI: 0.467-0.866) and antitumor therapy ( P<0.001, HR=0.439, 95% CI:0.308-0.626) were independent predictors of overall survival. Conclusion:There is high incidence of cholangitis in patients with unresectable Bismuth type Ⅳ hilar cholangiocarcinoma treated with endoscopic stenting. Longer stent patency can be achieved with metal stent placement and bilateral drainage. In addition, metal stent for drainage and antitumor therapy can also help increase the survival benefit.

Objective:To explore the phenotypes and genotypes of molybdenum cofactor deficiency type B (MoCD-B) manifested as Leigh-like syndrome.Methods:The clinical data, laboratory tests, neuroimaging and gene results of one patient diagnosed as MoCD-B at Beijing Children′s Hospital and Hebei Children′s Hospital in December 2018 were collected. Related literature was searched and reviewed at Wanfang Data Knowledge Service Platform, China National Knowledge Infrastructure and PubMed (up to September 2020) by using terms "MOCS2" "molybdenum cofactor deficiency" "Leigh-like syndrome,MOCS2" "molybdenum cofactor deficiency, Leigh-like syndrome". The phenotypes and genotypes of MoCD-B were summarized.Results:A 7 months and 14 days old boy with the chief complaint of "cough for 6 days, abnormal posture for 4 days and fever for 2 days" was admitted to Hebei Children′ Hospital on December 2018. His abnormal posture presented as opisthotonos accompanied with dysphagia, without seizures. His previous psychomotor development was described as normal. He was born at term after an uneventful pregnancy to non-consanguineous parents. Blood test showed a slightly increased lactic acid and a significantly decreased uric acid. Urine metabolism test showed an obviously increased xanthine and hypoxanthine. Brain magnetic resonance imaging showed hyperintense signal on T2 weighted image and fluid attenuated inversion recovery in bilateral globus pallidus and pedunculus cerebri. The patient was diagnosed with Leigh-like syndrome. No obvious improvement was achieved after cocktail therapy and symptomatic treatment. The whole exome sequencing showed that the patient carried a homozygous variant of MOCS2 gene, c.19G>T(p.Val7Phe), which was a previously reported pathogenic site in the literature and could cause MoCD-B. His parents carried a heterozygous variant respectively. A total of 41 MoCD-B cases with MOCS2 gene variants were collected through literature review and our study, among which 30 cases had full medical records. The onset ages of 23 (77%) cases were in neonate, manifesting with severe encephalopathy, including neonatal-onset intractable seizures, developmental delay, laboratory abnormalities included very low levels of serum and urinary uric acid, increased urinary levels of xanthine and hypoxanthine. Cranial imaging showed cerebral atrophy, cystic encephalomalacia, etc. The onset ages of 7 patients varied from 5 months to 23 years. Four cases had normal psychomotor development before disease onset. Neurological disorders appeared acutely or exacerbated after external triggers and all of them had basal ganglia involvement. Among the 30 cases, 3 cases had a relatively milder phenotype with the ability of brief communication and walking without or with support.Conclusions:Molybdenum cofactor deficiency is a rare disease. Most cases had severe phenotypes and poor outcomes, but some cases may have mild phenotype. MoCD-B caused by MOCS2 gene variants may manifest as Leigh-like syndrome with a normal psychomotor development before the trigger of infection strike. Hypouricemia, xanthinuria and hypoxanthinuria can be indicators of the disease. The presence of MOCS2 gene variants would confirm a final diagnosis.

Objective To explore the phenotype and genotype of mitochondrial DNA depletion syndromes (MDS) in Chinese children.Methods The clinical and genetic data of 12 MDS patients (8 were boys and 4 were girls) diagnosed in the Department of Neurology in Beijing Children's Hospital,Capital Medical University from October 2010 to April 2018 were retrospectively collected and analyzed.Results The developmental milestones were normal or mildly retardated before disease onset.The age of onset ranged from 0 to 2.9-year-old.Most cases developed postnatal or after infection.The most common initial symptoms were feeding difficulty,seizure,muscle weakness,psychomotor regression and hepatic dysfunction.At the last evaluation,all the patients had developmental retardation,failure to thrive,muscle weakness,and dysphagia.Other clinical features were weight loss (9 cases),hearing impairment (7 cases),ptosis (6 cases),seizure (5 cases),dyspnea (4 cases),visual impairment (1 case),hirsutism (1 case),lactic acidosis (7 cases),elevated hepatic enzymes (4 cases) and creatine kinase (2 cases),elevated protein in cerebrospinal fluid (3 cases),abnormalities on screening for inborn error of metabolism (10 cases) and brain magnetic resonance imaging (MRI) (10 cases),abnormal electromyogram (including neurogenic or myogenic injury) (5 cases).Five patients died of infection or multiple organ failure.A total of 18 novel mutations presented below were detected in these patients.Among the 6 cases of encephalomyopathy,there were 3 with SUCLG1 mutation (c.916G＞T,c.619T＞C,c.980dupT were novel),2 with SUCLA2 mutation (c.851G＞A,c.971G＞A were novel),and one with RRM2B mutation (c.456-2A＞G,c.212T＞C were novel).All the cases of hepatic encephalopathy all had POLG mutations (c.3151G＞A,c.2294C＞T,c.2858G＞C,c.680G＞A and c.150_158delGCAGCAGCA were novel).Two cases of infantile-onset spinocerebellar ataxia had TWNK mutations (c.1163C＞T,c.1319T＞C,c.1388G＞A and e.257_258delAG were novel).One case of myopathy had TK2 mutations (c.557C＞G and c.341A＞T were novel).Conclusions The clinical and genetic features of MDS were heterogeneous.Eighteen novel mutations in six MDS related genes were reported,which expanded the genetic spectrum of MDS in Chinese children.
