ABSTRACT

In recent years, the incidence of renal cancer has been increasing continuously. Surgical resection is the "gold standard" for the treatment of small renal cancer. However, local ablation therapy of renal cancer is undoubtedly the best choice for patients with short life expectancy, other complications, and impaired renal function who are not suitable for surgery. In recent years, with the development of ablation techniques and long-term follow-up, local ablation has shown good therapeutic effects. As many domestic hospitals are performing or planning to perform renal tumor cryoablation to improve the clinical cure rate and surgical safety of renal tumor cryoablation, it is necessary to standardize the surgical indications, contraindications, perioperative management, efficacy evaluation, and other common problems. Currently, there is no expert consensus regarding perioperative renal tumor cryoablation in China. To standardize the perioperative management of renal tumor cryoablation and related technical operations in clinical practice, and improve the effectiveness and safety of cryoablation, the expert committee of Tumor Interventional and Minimally Invasive Diagnosis and Treatment Continuing Education Base of the Chinese Anti-Cancer Association convened experts in related fields to discuss and formulate this consensus, which is hereby published, for clinical reference and application.

ABSTRACT

Tomato (Solarium lycopersicum) is one of the most popular vegetables worldwide and is a classic model plant for studying fruit development and ripening due to its short growth cycle, clear genetic background and ease of molecular manipulation. This paper used virus-induced gene silencing (VIGS) to construct SlWRKY53b gene-silenced tomato fruits and analyzed the effect of SIWRKY531) gene silencing in the tomato fruit ripening process. We found that transient silencing of SIWRKY531) resulted indelayed in-broken color, higher chlorophyll contents (P<0.05) and reduced carotenoid contents (P<0.05) in tomato fruits, and color difference results indicated that the differences in L *, a * and b * values were consistent with fruit color changes. Further studies showed that genes significantly down-regulated (P<0.01) in SIWRKY531) gene-silenced tomato fruits include the chlorophyll degradation-related genes (AFCl, PAO, PPH, SGR1), carotenoid synthesis-related genes (PSYl, PDS, ZDS), ethylene synthesis pathway-related genes (ACOl, ACS2, NOR, AC03, EA, RIN), and cell wall degradation-related genes (PG, EXP, CELT.). Correlation analysis showed that the expression of SlWRKY53b was negatively correlated with chlorophyll contents and positively correlated with carotenoid contents and the expression of maturation-related genes. These results suggest that inhibition of SIWRKY531) expression at the transcrip-tional level can achieve the effect of delaying tomato fruit ripening, indicating that S1WRKY531) plays arole as a facilitator in the tomato fruit ripening process.

ABSTRACT

【Objective:】 To understand the current situation of narrative medical education for medical staff in China, and to explore the construction of the practice mode of medical humanistic spirit in the new era. 【Methods:】 The cross-sectional study and convenience sampling method were used to conduct an online questionnaire survey on the knowledge, attitude and behavior of 2,145 medical staff about narrative medicine in China. 【Results:】 The knowledge of the surveyed medical staff about narrative medicine was at a lower moderate level. Nearly 70% of the medical staff had a positive attitude toward learning and using narrative medicine, with a high degree of recognition, but 30% of medical staff still had a negative attitude toward narrative medicine practices such as parallel medical records. The frequency of related behaviors among medical staff was low, and the proportion of people who evaluated the questions as positive accounted for about 40%, especially about 30% of the people evaluated as positive in narrative medicine practice projects. 【Conclusion:】 Narrative medical education in China is at the primary stage and is facing many tests such as the effectiveness of the transformation of theoretical results. The healthy and sustainable development of narrative medical education must be combined with the practical experience of medical humanities education at home and abroad to explore narrative programs with Chinese characteristics. Narrative medical education focuses on the three links of "narrative medical knowledge, attitude and behavior" and closely links its humanistic connotation, which is of great significance to enrich and innovate the medical humanistic education model.

ABSTRACT

【Objective:】 To understand the knowledge, attitude and behavior of Chinese medical personnel on narrative medicine. 【Methods:】 2 145 domestic medical staff were investigated through online questionnaire by convenient sampling. 【Results:】 The scoring rates of knowledge, attitude and behavior of narrative medicine among medical personnel were 49.62%, 47.18%, and 41.43% respectively. 【Conclusion:】 From the cognitive perspective, although most of the participants were familiar with the big framework of narrative medicine, they knew little about the specific methods and tools. As for attitude, medical staff can still further learn the attitude and identity of narrative medicine related theories. But the overall attitude was positive, which laid a foundation for further promoting narrative medicine. From the behavioral perspective, medical personnel’s reading and writing frequency of disease narrative stories was relatively low. In the future, relevant skills training and habit cultivation should be strengthened.

ABSTRACT

OBJECTIVE@#To investigate whether blood-brain barrier (BBB) served a key role in the edema-relief effect of bloodletting puncture at hand twelve Jing-well points (HTWP) in traumatic brain injury (TBI) and the potential molecular signaling pathways.@*METHODS@#Adult male Sprague-Dawley rats were assigned to the sham-operated (sham), TBI, and bloodletting puncture (bloodletting) groups (n=24 per group) using a randomized number table. The TBI model rats were induced by cortical contusion and then bloodletting puncture were performed at HTWP twice a day for 2 days. The neurological function and cerebral edema were evaluated by modified neurological severity score (mNSS), cerebral water content, magnetic resonance imaging and hematoxylin and eosin staining. Cerebral blood flow was measured by laser speckles. The protein levels of aquaporin 4 (AQP4), matrix metalloproteinases 9 (MMP9) and mitogen-activated protein kinase pathway (MAPK) signaling were detected by immunofluorescence staining and Western blot.@*RESULTS@#Compared with TBI group, bloodletting puncture improved neurological function at 24 and 48 h, alleviated cerebral edema at 48 h, and reduced the permeability of BBB induced by TBI (all P<0.05). The AQP4 and MMP9 which would disrupt the integrity of BBB were downregulated by bloodletting puncture (P<0.05 or P<0.01). In addition, the extracellular signal-regulated kinase (ERK) and p38 signaling pathways were inhibited by bloodletting puncture (P<0.05).@*CONCLUSIONS@#Bloodletting puncture at HTWP might play a significant role in protecting BBB through regulating the expressions of MMP9 and AQP4 as well as corresponding regulatory upstream ERK and p38 signaling pathways. Therefore, bloodletting puncture at HTWP may be a promising therapeutic strategy for TBI-induced cerebral edema.

ABSTRACT

Nonalcoholic fatty liver disease (NAFLD) is regarded as the most common liver disease with no approved therapeutic drug currently. Silymarin, an extract from the seeds of Silybum marianum, has been used for centuries for the treatment of various liver diseases. Although the hepatoprotective effect of silybin against NAFLD is widely accepted, the underlying mechanism and therapeutic target remain unclear. In this study, NAFLD mice caused by methionine-choline deficient (MCD) diet were orally administrated with silybin to explore the possible mechanism and target. To clarify the contribution of peroxisome proliferator-activated receptor α (PPARα), PPARα antagonist GW6471 was co-administrated with silybin to NAFLD mice. Since silybin was proven as a PPARα partial agonist, the combined effect of silybin with PPARα agonist, fenofibrate, was then evaluated in NAFLD mice. Serum and liver samples were collected to analyze the pharmacological efficacy and expression of PPARα and its targets. As expected, silybin significantly protected mice from MCD-induced NAFLD. Furthermore, silybin reduced lipid accumulation via activating PPARα, inducing the expression of liver cytosolic fatty acid-binding protein, carnitine palmitoyltransferase (Cpt)-1a, Cpt-2, medium chain acyl-CoA dehydrogenase and stearoyl-CoA desaturase-1, and suppressing fatty acid synthase and acetyl-CoA carboxylase α. GW6471 abolished the effect of silybin on PPARα signal and hepatoprotective effect against NAFLD. Moreover, as a partial agonist for PPARα, silybin impaired the powerful lipid-lowering effect of fenofibrate when used together. Taken together, silybin protected mice against NAFLD via activating PPARα to diminish lipid accumulation and it is not suggested to simultaneously take silybin and classical PPARα agonists for NAFLD therapy.

ABSTRACT

Usher syndrome (USH) is the most common cause of deaf-blindness diseases characterized by sensorineural hearing loss and retinitis pigmentosa. Patients are clinically and genetically heterogeneous, however, there are no convincing methods for prevention and treatment. USH2A is the most common disease-causing gene among 14 genes related to Usher syndrome. Great progress has been achieved in the pathogenic mechanism, animal models studies, diagnosis, and treatments based on gene therapy, cells transplantation and antisense oligonucleotide-based splice correction. Mutations in USH2A result in defects in USH complex proteins which involved in the transport function of the peripheral cilia region. There is respective limitations in established mouse and zebrafish animal models. Two promising treatments of this disease are introduced. One is clinical transplantation of visual organs which induced from corrected patient-derived induced pluripotent stem cells by the CRISPR/Cas9 system and another one is the RNA splicing therapy based on antisense oligonucleotides.

ABSTRACT

BACKGROUND@#This study was designed to evaluate the clinical and radiographic outcomes of patients with nutcracker syndrome (NCS) who were treated with three-dimensional printing (3DP) extravascular titanium stents (EVTSs). The 3DP EVTS was expected to release the hypertension of the left renal vein (LRV) produced by its compression between the superior mesenteric artery (SMA) and the aorta without causing any complications.@*METHOD@#The pre-operative kidney model of each patient was printed out to enable surgical planning. After that, the EVTS was designed based on the LRV's primitive physiologic structure using computer-aided design software, and each stent was printed out with a precision setting of 20 μm. Seventeen patients who had been suffering from NCS underwent laparoscopic 3DP EVTS placement. The surgical procedure was designed for the placement of EVTS, taking great care in positioning and fixing the stent. Surgical data, which included patient demographic characteristics as well as pre- and post-operative test results, were collected and analyzed.@*RESULTS@#The mean duration of surgery was 75 ± 9 min, and the mean blood loss was 20 ± 5 mL. Computed tomography examinations revealed that the pre- and post-operative angle between the SMA and the aorta ranged from 18.7° ± 4.3° to 48.0° ± 8.8° (P < 0.05); in patients with left varicocele, the mean diameter of the left spermatic vein ranged from 3.7 ± 0.5 to 1.3 ± 0.2 mm (P < 0.05). Moreover, Doppler ultrasound examinations showed that the peak velocity of blood flow at the hilar area ranged from 12.4 ± 3.3 to 18.5 ± 3.4 cm/s (P < 0.05). No side effects were observed in the 24 to 42 months following surgery.@*CONCLUSION@#The findings after 2 years of follow-up suggest that the 3DP EVTS is a safe and effective minimally invasive alternative for the treatment of NCS.

ABSTRACT

Objective To analyze the clinical manifestation and CYP4V2 mutations of Bietti crystalline corneoretinal dystrophy( BCD) families. Methods Total of 234 patients (173 families) diagnosed as BCD were recruited in Peking University Third Hospital from 2010 to 2018. All of the subjects underwent comprehensive eye examinations to observe the clinical manifestations. Blood samples were collected and genomic DNA was extracted. The Sanger sequencing or high- throughput sequencing was applied for CYP4V2 gene mutation analysis. This study was approved by the Ethics Committee of Peking University Third Hospital (NO. 2012093). All patients and their family members signed informed consent. Results Some patients manifested the typical phenotype of BCD characterized by yellowish-white crystalline deposits throughout the fundus. However,some patients in advanced stage were easily misdiagnosed as other inherited retinal degeneration because the crystalline deposits diminished or even disappeared. Forty-nine probands in our cohort were misdiagnosed as other inherited retinal degeneration at first visit, with a misdiagnosis rate of 28. 3%. Genetic diagnosis results showed that 161 patients carried CYP4V2 mutation,and the positive rate was 93. 1%. Eight novel mutations were obtained. The three known mutations c. 802-8 _810del17bp, c. 1091-2 A>G and c. 992 A>C accounted for 73. 5% of the mutations, which were hotspots in Chinese Han populations for BCD. Conclusions Patients with BCD have characteristic fundus manifestation, but are easily misdiagnosed in advanced stage. Molecular diagnosis is valuable in clinical diagnosis of the disease,thus contribute to the prevention and treatment of the disease. A single hybrid mutation is not enough to lead to BCD. No apparent genotype-phenotype correlation between the CYP4V2 gene and occurrence of BCD is identified.

ABSTRACT

Objective To explore the associations between physiological factors, psychosocial factors, dietary habits, lifestyles and hyperuricemia (HUA) and provide the evidence for hyperuricemia intervention. Methods From 2016 to 2017, adults during their checkup in the health management center of the Second Affiliated Hospital of Dalian Medical University were interviewed with self-designed questionnaire and received the health examinations. To determine the influence of socio-economic data, life style habits and psychological factors on the risk of HUA, the classification tree model was adopted. Results A total of 4 118 subjects were enrolled in the study, with an average age of (52.8±7.9) years. The results showed that the prevalence of HUA was higher among people under 30 years old and 40-50 years old who are smoking, drinking and doing the sedentary work, who unsatisfied with their work and under a great mental stress. Factor analysis model identified three dietary patterns, traditional model,fried and smoked food and dessert model and high quality protein model, the cumulative variance contribution rate was 53.886%. In multivariate model, it was found that high-quality protein pattern, physical exercise and fasting plasma glucose (FPG) were negatively associated with HUA. Male, smoking, drinking, having dyslipidemia, higher body mass index (BMI) were risk factors for HUA. Subgroup analysis showed that in both male and female, the high-quality protein patterns were negatively associated with HUA. The pattern of fried and smoked food and dessert patterns was the independent risk factors for HUA in female. Classification tree model showed that male, dyslipidemia, higher BMI grade, and the fried and smoked food and dessert pattern were the risk factors for HUA. Conclusions The influencing factors of HUA in different gender were different, which indicate the individualized health management should be adopted. Male who is overweight or obese should quit smoking and drinking. Women should pay more attention to avoid of the excess intake of fried and smoked food and dessert. Meanwhile, a high-quality protein diet and more physical exercise should be encouraged.

ABSTRACT

Objective:This article analyzes the cognition and satisfaction evaluation of patients in medical alli-ance. Under the medical alliance mode,the present study tries to explore the choice of medical treatment of patients, the first diagnosis of primary health care institutions and its influencing factors, in order to provide reference for the construction of medical alliance. Methods:With the help of stratified sampling method,eighteen (18) medical alli-ances were selected from 16 districts and counties in Beijing. The survey questionnaire was designed to be used as the tool for data collection. A total of 1 280 patients in medical alliance participated in this study. The Chi-square Test and binary logistic regression model were used for statistical analysis. Results:59.12% of patients understand the medical association and related policies. 39.12% of the patients are satisfied with the medical association,51.44% of patients are willing to take first diagnosis at primary health care institutions. The distribution of medical resources in various districts is uneven. The type of hospital visited,the degree of understanding of medical alliance,the expe-rience of medical alliance and the satisfaction toward medical alliance will have an impact on the willingness about basic initial diagnosis,and the influence make a significant statistical sense. Conclusions:The Medical alliance con-struction in Beijing has achieved a certain effect,as first visit at primary health care institutions will be the initial for-mation. But the unbalanced distribution of medical resources in various districts,the service capacity of primary care institutions which does not meet the needs of patients,the insufficient sensitization of relevant policy and the current health insurance policy are seen as limiting factors to the development of medical alliance.

ABSTRACT

Objective:In this study,through the description of understanding,behavior,evaluation about med-ical alliances,we explore the problems and made recommendations to medical alliances. Methods: A questionnaire survey was conducted on 556 medical staff in 18 medical alliances in Beijing. We used descriptive statistical methods to analyze the situation of cognition and so on. And we compared medical staff evaluation of medical alliances be-tween core hospital and cooperative hospital. Results: Only 5.40 % of medical staff are totally unaware of the medical alliances policy. 38.73 % of the doctors don't conduct two-way referral. 55.69 % of the doctors in the core hospital don't come to the cooperative hospital. 71.40 % of the medical staff think that the operation of the medical alliances is good. There are big differences in the distribution of overall evaluation between core hospital medical staff and cooperative hospital medical staff by rank sum test. Conclusion: The understanding of medical alliances and the evaluation of activities are better. However, the two-way referral effect is not obvious and some specific activities are not ideal.
