Objective:To explore surgical strategies for acute type A aortic dissection involving severe stenosis or occlusion of the carotid arteries.Methods:From January 2019 to March 2023, a total of 29 patients with acute type A aortic dissection involving severe stenosis or occlusion of the carotid arteries were included in the study. All patients underwent emergency surgery, with simultaneous intraoperative neck incision and replacement of the unilateral or bilateral carotid arteries. Among them, there were 19 males with a mean age of(49.57±2.14)years old. Preoperative brain CT indicated abnormalities in 15 cases, transient neurological dysfunction occurred in 5 cases, and syncope in 1 case.Results:Procedures included ascending aorta replacement in 10 cases, Bentall procedure in 18 cases, and Wheat procedure in 1 case. Arch operations involved partial arch replacement in 3 cases and Sun’s procedure in 26 cases. Simple left carotid artery replacement was performed in 6 cases, simple right carotid artery replacement in 19 cases, and bilateral carotid artery replacement in 4 cases. Cerebral protection measures during circulatory arrest included unilateral cerebral perfusion in 24 cases and bilateral cerebral perfusion in 5 cases. The mean operation time was(7. 6±0. 3) h, with a mean cardiopulmonary bypass time of(196. 3±8. 7) min, aortic cross-clamp time of(113.2±6.4) min, ischemic time 12(5-16.5) min, and lowest temperature of(26.3±0.4)°C. One patient experienced in-hospital mortality. Postoperatively, new neurological dysfunction occurred in 2 cases, including 1 case with coma and permanent neurological deficit.Conclusion:In patients with acute type A aortic dissection involving severe stenosis or occlusion of the carotid arteries, simultaneous carotid artery replacement via neck incision during aortic surgery is a safe and reliable surgical approach.

[Objective]To explore the connotation of the theory of"normal Qi and blood flow forward,stagnation and rebellion will lose their consciousness"and its clinical treatment of epilepsy.[Methods]Through consulting Huangdi Neijing and later medical classics,this paper analyzed the theoretical basis of"normal Qi and blood flow forward,stagnation and rebellion will lose their consciousness",and explained the epilepsy mechanism and treatment rules and prescriptions according to this principle.[Results]The occurrence of epilepsy is related to the incompatibility of Qi and blood between the five organs and a stoppage of the circulation of tri-Jiao,while epilepsy's long course is due to the reversal of Qi and blood of each organ itself,that leads the production of stagnation.Prescriptions are based on Chaihu Jia Longgu Muli Decoction,which is added or subtracted herbs according to symptoms,while also comforting the patient that epilepsy can be treated.The attached medical record was identified as Qi blockage,pyrophlegm affecting the mind,the treatment was to clear heat from liver,eliminate phlegm for resuscitation.Modified Chaihu Jia Longgu Muli Decoction plus Ditan Decoction was used and good results were achieved.[Conclusion]This theory reveals the consciousness,Qi,blood,Yin and Yang of the human body cannot be reversed,and the truth that it flows sequentially between the organs,and that each organ runs like a headless ring.The principle of treatment is"unobstruct",which aims to smooth the"Shidao",restore the normal function of the five internal organs,treat both manifestation and root cause of disease,finally make the consciousness clear.Using modified Chaihu Jia Longgu Muli Decoction,and with words of relief,the epilepsy will be relieved.

Abstract: Objective To analyze and compare the differences in serum lipid metabolomics between patients with moderate to severe acne and healthy controls to understand the characteristics of serum lipid metabolism in acne patients. Methods Serum samples were collected from 30 patients with moderate to severe acne and 30 healthy controls matched for age, gender and body mass index in the Department of Dermatology, the Affiliated Hospital of Southwest Medical University from May 2019 to Apr. 2020. Serum lipid metabolomics was analyzed by liquid chromatography-tandem mass spectrometry. Partial least squares discriminant analysis (PLS-DA) was used for multivariate statistical analysis of differentially expressed lipid metabolites. The metabolic pathways with significant differences between the two groups were screened by Kyoto Encyclopedia of Genes and Genomes (KEGG) database. Using Mann-Whitney U test to calculate differential metabolites. Spearman correlation analysis was used to analyze the correlation between serum PC (18: 2e/20: 2) concentration and acne severity. Results The PLS-DA results showed that the composition of serum lipid metabolites in acne patients was significantly separated from that in healthy controls. Of the top 30 lipid metabolites with the most significant differences, four kinds of triglycerides (TG), two kinds of diglycerides (DG), six kinds of phosphatidylcholine (PC), one kind of MePC, two kinds of sphingomyelin (SM), two kinds of phosphatidylinositol (PI), two kinds of ceramide (monohexosyl ceramide, Hex1Cer;dihexosyl ceramide, Hex2Cer), two cardiolipin (CL) were found to be increased in the acne group (P<0.05). The levels of one kind of DG, two kinds of lysophosphatidyl ethanolamines (LPE), one kind of dimethylphosphatidyl ethanolamine (dMePE), one kind of bismethyl phosphatidic acid (BisMePA), three kinds of phosphatidyl ethanolamine (PE) and one kind of ceramide were found to be decreased in the acne group (P<0.05), and most of them belonged to phospholipid metabolites. Spearman correlation analysis showed that serum PC (18:2e/20:2) concentration was positively correlated with acne severity (r=0.456, P=0.004). KEGG enrichment function analysis revealed that the differential lipid metabolites were primarily enriched in metabolic pathways such as sphingolipid signaling pathway, cholesterol metabolism, insulin resistance, glycerophospholipid metabolism, among which the sphingolipid signaling pathway may play an important role. Conclusion There are significant differences in serum lipid metabolism between acne patients and healthy controls. Lipid metabolism disorders may be related to the pathogenesis of acne, but it’s molecular mechanism still needs further experimental exploration.

Objective To investigate the status of maternal iodine deficiency in Lishui City of Zhejiang Province， and explore the effect of maternal iodine deficiency on the growth and development of infants. Methods A total of 209 pregnant women living in Liandu District of Lishui City from January 2017 to December 2018 were selected by stratified sampling method. Urine iodine level in pregnant women and iodine content in edible salt at home were determined to assess the status of iodine deficiency and to analyze the influencing factors. Their babies were followed up for 1 year， and metabolic disease screening and physical examination were carried out to evaluate the growth and development. Results The median of urinary iodine levels in 2017 and 2018 were 165 µg·L^-1 and 192 µg·L^-1， respectively. Both of the values met the standard of iodine sufficiency. The results of salt iodine content in pregnant women's homes showed that 7 cases （3.35%） were without iodized salt and 202 cases （96.65%） with iodized salt， including 186 cases （89.00%） with qualified iodized salt. Univariate analysis showed that pregnancy， education level， intake of iodized salt， cooking methods of salt， intake frequency of iodine-rich food and knowledge of iodine nutrition had significant impact on iodine deficiency in pregnant women （P<0.05）. Logistic regression analysis showed that early pregnancy （OR=1.626） and adding salt into heat oil （OR=1.874） were risk factors for iodine deficiency in pregnant women， while intake of qualified iodized salt （OR=0.593） was a protective factor. Follow-up results showed that there were no abnormalities in newborn screening， and babies of 2 women （2.41%） with iodine deficiency were short in height at 1， 6 and 12 months of age. Conclusion Attention should be paid to the monitoring of pregnant women's urinary iodine levels to guide the scientific supplementation of iodine， so as not to affect the growth and development of infants.

Objective:To explore the real experience of nutritional support in patients with chronic heart failure and acute decompensation during hospitalization, understand the common needs, so as to provide a reference for implementing targeted support and constructing nutritional support programs for this group in the future.Methods:From January to February 2022, 15 patients with chronic heart failure and acute decompensation in Jiading District Central Hospital Affiliated Shanghai University of Medicine &Health Sciences were interviewed in depth in a one-to-one, semi structured way using the purposeful sampling method. Colaizzi phenomnological 7-step analysis method was applied to analyze, summarize and refine the theme.Results:Through detailed analysis of data, five themes were extracted, namely, diversification of emotional experience, polarization of nutrition emphasis, dissatisfaction with hospital nutrition support, health related behavior change, and internal drive.Conclusions:Acute decompensated patients with chronic heart failure experience a variety of emotional experiences on nutritional support during hospitalization, and are dissatisfied with hospital nutritional support. Their attention to nutrition is polarized. The change of health behavior is manifested in the awareness of nutrition, positive change and willingness to participate in nutrition decision-making. Therefore, medical staff should speed up and improve the promotion of nutritional support programs for patients with chronic heart failure to promote their rehabilitation and improve their quality of life.

Objective:To study the risk factors of massive bleeding in patients with acute Stanford type A aortic dissection undergoing moderate hypothermic circulatory arrest repair.Methods:From January 2016 to October 2017, 486 consecutive patients with acute type A aortic dissection were included in the study. All operations were performed with moderate hypothermic circulatory arrest. The basic clinical data of patients were collected retrospectively. Massive bleeding was defined according to definition of Universal Definition of Perioperative Bleeding(UDPB) 4 class and the Blood Conservation Using Antifibrinolytics in a Randomized Trial(BART). Significant variables in univariate analysis were included in multivariate logistic regression analysis. Results:Thirty-four patients(7.00%) died in hospital. A total of one hundred and eighty-seven patients(38.48%) fulfilled criteria of the definition of BART massive bleeding. Forty-five patients(9.26%), 8 patients(1.65%), 114 patients(23.46%), 147 patients(30.25%) and 172 patients(35.39%) were in grade 0, grade 1, grade 2 and grade 4, respectively. With BART as the end point, the result of multivariate logistic regression showed that female gender( OR=3.32, P<0.001), anemia( OR=2.24, P=0.04), clearance creatine≤85 ml/min( OR=1.93, P=0.01), D-dimer level(every 500 ng/ml increase, OR=1.02, P=0.003), cardiopulmonary bypass(CPB) time( OR=1.01, P<0.001), total arch replacement(TAR, OR=2.40, P=0.02) were independent risk factors for massive bleeding, and the time from onset to operation( OR=0.86, P=0.01) was protective factor. With UDPB 4 class as the end point, multivariate logistic regression showed that creatinine clearance≤85 ml/min( OR=2.05, P=0.001), CPB time( OR=1.01, P=0.04) were independent risk factors for massive bleeding. The time from anset to operation( OR=0.85, P=0.002) and Bentall procedure( OR=0.65, P=0.04) were the protective factors. Conclusion:Massive bleeding was more common in acute Stanford type A aortic dissection. Female gender, poor preoperative renal function, high D-dimer level, early time accepting surgical operation and long CPB were independent risk factors. For high-risk patients, simple and effective surgical methods should be taken to reduce the risk of bleeding.

Objective:To investigate the distribution characteristics of bacteria in urine of patients with ureteral stent crusting.Methods:Thirty-five patients who underwent ureteral stent placement at the Shandong Provincial Third Hospital, Shandong University Qilu Hospital, Jinan Central Hospital, and Jinan Jigang Hospital were selected from October, 2018 to March, 2019(the clinical study registration number is ChiCTR1800020025). The inclusion criteria were patients who had the stent intubated for 4 weeks after ureteroscopic lithotripsy, aged between 18 and 65 years. Exclusion criteria were patients with positive urine bacterial culture, severe gross hematuria, recent oral antibiotics, and patients with significant residual stones. This clinical study uses a cross-sectional study method, and those patients were divided into crusting group (n=23) and non-crusting group (n=12) according to the presence or absence of stent crusting. On the day of extubation, urine of the patients was collected for bacterial 16s DNA detection. The distribution characteristics of bacteria in urine of the two groups were analyzed using UPARSE, UCHIME and RDP calssifier. The total number of bacteria species, bacterial abundance and bacterial species with large-scale abundance in urine of the two groups were determined. The quantity of bacteria species and bacterial abundance in the urine between the two groups were compared, and the bacterial species with large-scale abundance in urine of the patients with stent crusting were identified.Results:There were no significant differences in general information such as age, body mass index, gender, affected side, type of stent tube, and stone composition between the two groups. Using 16s DNA sequencing to detect the bacteria in the urine of the two groups revealed that the number of bacterial species with abundance >1% was 11, and the number of bacterial species with abundance >0.01% was 74 in the crusting group. In the non-crusting group, the number of bacterial species with abundance >1% and >0.01% was 7 and 11, respectively. Compared with the non-crusting group, the number of bacterial species with abundance >1% in the crusting group was significantly larger ( t=5.12, P=0.000). In the crusting group, bacterial species with the top three abundance were g_Lactobacillus (23.1%), g_Bacteroides (18.8%) and g_norank_Bacteroides (17.1%). In the non-crusting group, bacterial species with the top three abundance were g_Escherichia-Shigella (32.2%), g_Enterococcus (24.9%) and g_Pseudomonas (18.2%). The three bacteria with the greatest difference between the two groups were g_ Lactobacillus ( P=0.010), g_Bacteroides ( P=0.004) and g_norank_Bacteroides ( P=0.004), respectively. Conclusion:The species and quantity of bacteria in the urine of patients with stent crusting are both significantly larger than those of patients without stent crusting. Bacteroides with larger-scale abundance in the urine of patients with stent crusting may promote the deposition of crystals on the stent wall through its structure, function and urease positive characteristics.

Objective    To evaluate the involvement of renal artery in acute Stanford type A aortic dissection (TAAD) using CT angiography (CTA) and to analyze the difference of renal function among different types of renal artery involvement. Methods    From January 2016 to November 2017, 151 patients of acute TAAD with renal artery involvement were included in the study. There were 118 males and 33 females, with an average age of 47.93±10.53 years. All patients underwent aortic CTA to confirm the TAAD. According to CTA，involvement of one side of renal artery can be divided into four types: type A, large tear near renal artery orifice, difficult to distinguish true or false lumen; type B, the orifice of the renal artery originates entirely from the false lumen; type C, the orifice of the renal artery originates entirely from the true lumen; type D, renal artery dissection is observed, renal artery intima can be seen. The levels of serum creatinine (sCr) and creatinine clearance (CC) in all groups were analyzed and compared. Results    The results of one-way ANOVA analysis showed that there was no significant difference in sCr or CC among the groups (P>0.05). There was no significant difference in age, sex, proportion of hypertension history and onset time among the above groups (P>0.05). Conclusion    The three most common types of renal artery involvement were BC type, CC type, and AC type. The types of renal artery involvement do not affect renal function.
