Transcriptomic analysis of the molecular mechanism of Tiaopi Chengqi decoction improving gastric digestive function in mice with food accumulation / 中国临床药理学与治疗学

AIM:To explore the molecular mechanism of Tiaopi Chengqi decoction (TpCqD) improving hyperthermia and high-protein food-induced hyperphagia mice based on transcriptomics. METHODS:C57 mice were randomly divided into a control group, model group, low-dose TpCqD group, high-dose TpCqD group, and domperidone group. The general condition of the experimental mice was observed and the average food intake was counted, and the rate of gastric emptying and intestinal propulsion was determined for each group of mice. H&E staining was used to observe pathological changes in gastric tissue. PAS staining was used to observe glycogen changes in gastric tissue. Pepsin activity was determined by colorimetry. pH value of gastric contents was measured by acid-base titration. Transcriptome sequencing was used to analyze the differential genes in gastric tissue, a volcano map and a cluster heat map were made for the differential genes, and KEGG was used to analyze the signal pathway enrichment of the differential genes. RT-qPCR verified the differential genes obtained by screening. RESULTS:After treatment with TpCqD, the body weight and average food intake of mice with food accumulation increased (P<0.05), and the intestinal propulsion rate and gastric emptying speed of mice with food accumulation accelerated (P<0.05). TpCqD could protect gastric tissue structure and glycogen degradation, increase pepsin activity (P<0.05), and reduce gastric content pH (P<0.05). Transcriptome results showed that TpCqD could regulate the expression of Acox2 and cilp2, regulate fat digestion and absorption, protein digestion and absorption, and pancreatic secretion signals. RT-qPCR showed that compare with model group, TpCqD up-regulated Acox2 (P<0.05) and down-regulated the mRNA level of cilp2 (P<0.05). CONCLUSION:TpCqD ameliorated digestive dysfunction in mice with high-calorie and high-protein diets leading to food accumulation involving the regulation of the fat and sugar metabolism genes Acox2 and cilp2, and pancreatic secretory signaling.

The effects of clinical rehabilitation pathway management on intubation time, dysfunction and medical cost for stroke survivors after tracheotomy / 中华物理医学与康复杂志

Objective:To document any effect of clinical rehabilitation pathway management on intubation time, dysfunction and medical expenditure associated with tracheotomy after a stroke.Methods:A total of 154 stroke survivors undergoing tracheotomy were randomly divided into an observation group and a control group, each of 77. Both groups were given routine rehabilitation, while the observation group was additionally provided with clinical rehabilitation pathway management during the rehabilitation intervention. Kaplan-Meier analysis was performed before the experiment and after 2, 4 and 6 weeks of treatment. Clinical pulmonary infection scores (CPISs), scores on the Chelsea Physical Function Assessment Scale (CPAx) and hospitalization cost were compared between the two groups.Results:The median extubation time of the observation group (2d) was significantly shorter than that of the control group (10d). After 2, 4 and 6 weeks of treatment, the average CPIS scores of the observation group were in each case significantly lower than those before treatment and the control group′s averages at the same time points, even though after 4 and 6 weeks of treatment the control group′s average CPIS scores had improved significantly. After 2, 4 and 6 weeks of treatment, the average CPAx scores of the observation group were significantly higher than those before treatment and better than the control group′s averages, even though the control group too had improved significantly compared with before the treatment. Hospitalization days, total hospitalization cost, antibiotic cost and laboratory examination cost of the observation group were, on average, significantly lower than those of the control group.Conclusion:Rehabilitation path management can shorten the period of intubation, prevent pulmonary infections, relieve dysfunction, and reduce medical expenses for stroke survivors after a tracheotomy. It is worthy of clinical promotion.

Expert consensus on perioperative nursing management of nutrition for elderly patients with hip fractures (version 2023) / 中华创伤杂志

Hip fractures are among the most common fractures in the elderly, presenting to be a leading cause of disability and mortality. Surgical treatment is currently the main treatment method for hip fractures. The incidence of perioperative malnutrition is increased after hip fractures in the elderly due to the comorbidities, decreased basal metabolic rate, accelerated protein breakdown, weakened anabolism and surgical stress. However, malnutrition not only increases the incidence of postoperative complications, but also leads to increased mortality, indicating an important role of perioperative nursing management of nutrition for the elderly patients with hip fractures. At present, there still lacks scientific guidance and application standards on perioperative nursing management of nutrition for the elderly patients with hip fractures. Therefore, the Orthopedic Nursing Committee of Chinese Nursing Association and the Editorial Board of Chinese Journal of Trauma organized relevant experts to formulate the Expert consensus on perioperative nursing management of nutrition for elderly patients with hip fractures ( version 2023) according to evidence-based medical evidences and their clinical experiences. Fourteen recommendations were made from aspects of nutrition screening, nutrition assessment, nutrition diagnosis, nutrition intervention and nutrition monitoring to provide guidance for perioperative nursing management of nutrition in elderly patients with hip fractures.

Mechanism of Nuclear Factor Erythroid 2-related Factor 2 Against Intestinal Fibrosis in Inflammatory Bowel Disease / 胃肠病学

Inflammatory bowel disease (IBD) is characterized by recurrent non ⁃ specific intestinal inflammatory responses. Intestinal fibrosis is an important cause of IBD complicated with intestinal obstruction. Nuclear factor erythroid 2⁃ related factor 2 (Nrf2) is a transcription factor that has anti ⁃ oxidative stress response in cells. In IBD, Nrf2 and its downstream regulated antioxidant enzymes achieve protective effects against intestinal fibrosis by inhibiting the activation of nuclear factor ⁃ κB, regulating T helper cell 17/regulatory T cell balance of intestinal immunity, and inhibiting transforming growth factor⁃β1/Smads signaling pathway. In this review, the structure of Nrf2, the specific mechanism of Nrf2's effect on intestinal fibrosis in IBD, and the recent studies on the treatment of IBD through Nrf2 pathway were reviewed in an attempt to provide a new direction for the prevention and treatment of IBD.

Effects and mechanisms of CD5 + CD19 + B lymphocytes on CD8 + cells in chronic hepatitis B virus infection / 中华消化杂志

Objective:To explore whether CD5 + CD19 + B cells has the function of secreteing interleukin-10 (IL-10) in vitro, and to further investigate its possible effects and mechanisms on CD8 + cells in the process of hepatitis B virus (HBV) infection. Methods:From July 2017 to June 2018, at Wuxi Second People′s Hospital Affiliated to Nanjing Medical University, 23 patients with chronic hepatitis B (chronic hepatitis B group), 18 patients with liver cirrhosis (liver cirrhosis group) and 19 healthy individuals in the same period as healthy controls (healthy control group) were enrolled. Peripheral blood mononuclear cell (PBMC) were isolated and cultured. CD5 + CD19 + B cells were isolated. The cells were analyzed by flow cytometry. The ratio of high CD5 + CD19 + B cells content (>6 % of lymphocytes), the secretion of IL-10 by CD5 + CD19 + B and the ratio of high IL-10 + cells content (>4 % of lymphocytes) of three groups were compared. The effects and possible mechanisms of CD5 + CD19 + B cells on the secreting of interferon-γ (IFN-γ) by CD8 + cells were analyzed. Liver biopsy and immunohistochemistry examination were conducted in 18 patients (13 patients with chronic hepatitis B and 5 patients with liver cirrhosis) and the expression of CD5 + CD19 + B cells in human liver tissues was analyzed. Chi square test and Fisher exact probability test were used for statistical analysis. Results:The ratio of high CD5 + CD19 + B cells content of liver cirrhosis group was higher than that of healthy control group (8/18 vs. 2/19) and the difference was statistically significant (Fisher exact probability test, P=0.029). The precentage of CD5 + CD19 + B cells in healthy control group ( n=10), chronic hepatitis B group ( n=23) and liver cirrhosis group ( n=18) accounted for 81.6%, 82.3% and 70.1%of IL-10 + cells, respectively, and the number of patients with high IL-10 + cells precentage was 2, 7 and 2, respectively. There were no statistically significant differences among three groups (all P>0.05). After stimulated with lipopolysaccharide and cultured for 48 hours, the precentage of CD8 + IFN-γ + cells in lymphocytes of healthy control group ( n=10), chronic hepatitis B group ( n=10) and liver cirrhosis group ( n=10) were compared, and the differences were not statistically significant (all P>0.05). After CD5 + CD19 + B cells were eliminated, the precentage of CD8 + IFN-γ + cells in lymphocytes increased in 5, 4 and 4 patients of healthy control group ( n=10), chronic hepatitis B group ( n=10) and liver cirrhosis group ( n=10). After adding IL-10 receptor blocker, the precentage of CD8 + IFN-γ + cells in lymphocytes in PBMC increased compared with that before the addition of IL-10 receptor blocker (7.23% vs. 6.87%). The results of immunohistochemistry examination of liver biopsy indicated that CD4 + and CD8 + cells were strong expressed in portal area of liver tissue of patients, while CD5 + and CD19 + were less expressed. Conclusions:CD5 + CD19 + B cells do not show obvious quantitative and functional differences in the process of chronic HBV infection, however the ability of CD8 + cells to secrete IFN-γ, which may be achieved by secreting IL-10 rather than by direct contact between cells.

Objective:To investigate the indication of pre-cut-endoscopic mucosal resection (pre-cut-EMR) on the treatment of colorectal laterally spreading tumors (LSTs).Methods:A retrospective study was performed on data of colorectal LSTs patients, who underwent pre-cut-EMR in Wuxi Second People’s Hospital and Zhongshan Hospital from January 2014 to June 2019. The relationships between the clinical characteristics of the lesions and the success rate and complications of pre-cut-EMR were analyzed.Results:Data of 132 colorectal LSTs cases were included in the study. Morphology of 29 (22.0%) LSTs were homogeneous granular type, 43 (32.6%) LSTs were mixed non-granular type, 58 (43.9%) LSTs were flat elevated type, and 2 (1.5%) LSTs were pseudo-depressed type. The diameter of lesions was 2.3±1.5 cm (ranged from 2.0 cm to 5.0 cm). Among the 132 LSTs, 36 (27.3%) tumors were located in rectum, 15 (11.4%) in sigmoid colon, 10 (7.6%) in descending colon, 17 (12.9%) in splenic flexure of colon, 21 (15.9%) in transverse colon, 24 (18.2%) in hepatic flexure of colon, 6 (4.5%) in ascending colon, and 3 (2.3%) in cecum. The histopathological diagnoses of the 132 LSTs included low grade intraepithelial neoplasia in 58 cases (43.9%), high grade intraepithelial neoplasia in 69 cases (52.3%), intramucosal carcinoma in 2 cases (1.5%), and canceration in 3 cases (2.3%). Pre-cut-EMR was achieved in all 132 patients, and the operation time was 25.3±13.6 min (ranged 20-65 min). The rate of en bloc resection and complete resection were 95.5% (126/132) and 100.0% (132/132), respectively. Two cases (1.5%) had intraoperative perforation, and were both located in the sigmoid colon with the diameter of 4.0 cm and 4.5 cm, respectively. Twelve cases (9.0%) had immediate bleeding during operation, and 2 cases (1.5%) had delayed bleeding after operation. Patients had been followed up for 6-24 months, the wound healed well after operation, and no local recurrence was found.Conclusion:Pre-cut-EMR is an effective and safe therapy for colorectal LSTs with diameter less than 4.0 cm.

Application of bioelectrical impedance vector analysis to evaluate volume status of hemodialysis patients with hypertension / 中华肾脏病杂志

Objective:To evaluate the volume status of hemodialysis patients with hypertension by bioelectrical impedance vector analysis, and investigate the effect of high volume status on the prognosis of patients with hypertension.Methods:The study subjects came from the patients with pre-dialysis systolic blood pressure>160 mmHg (mean systolic blood pressure of 6 times of treatment) in the Affiliated BenQ Hospital of Nanjing Medical University. According to the volume status assessed by bioelectrical impedance vector analysis, patients were divided into two groups: fluid overload group and non-overload group (including normal fluid status and fluid decline). The clinical data, laboratory test results, ratio of intracellular and extracellular water (ICW and ECW), body cell mass, lean body mass and the percentage of total body weight, fat percentage of body weight, resistance/height, reactance/height, phase angle and illmarker were compared between two groups. Kaplan-Meier survival curve was used to compare the difference of survival rate between the two groups.Results:A total of 51 hemodialysis patients with hypertension were enrolled in this study, including 19 patients in fluid overload group and 32 patients in non-overload group (27 patients with normal volume status and 5 patients with decreased volume). The levels of albumin, prealbumin, hemoglobin, hematocrit and serum phosphorus in patients with fluid overload decreased significantly compared with non-overload patients (all P<0.05), and the proportion of lymphocytes increased in fluid-overload patients ( P<0.05). The ratio of extracellular water and illmarker index in fluid overload group were significantly higher than those in the other group (both P<0.01). However, phase angle, resistance/height, reactance/height were lower than those in patients with non-overload (all P<0.01). After 20 months of clinical observation, the control rate of blood pressure (pre-dialysis systolic blood pressure<160 mmHg) in fluid overload group was lower than that in the non-overload group (26.3% vs 43.8%), but not statistically significant ( P=0.218). The all-cause mortality rate of patients in the fluid overload group was higher than non-overload group (26.3% vs 15.6%). Kaplan-Meier survival curve analysis suggested that the difference in survival rate between the two groups was not statistically significant. Conclusions:The extracellular fluid of hemodialysis patients with hypertension and fluid overload increases significantly, and the nutritional status evaluation index decreases compared with that of patients without increased volume. Increased proportion of lymphocytes may be related to the micro-inflammatory status. Blood pressure is more difficult to control in hypertensive patients with fluid overload and the clinical prognosis can be worse in patients without increased volume.

Chi-square test and rank sum test were carried out to analyze differences between pre- and post-treatment expression rate and intensity of VEGF and PCNA, and Spearman correlation analysis was conducted to analyze the correlations between the protein expression of VEGF and PCNA.@*Results@#The expression rates of VEGF and PCNA in keratinocytes in the CA tissues were 71.43% (40/56) and 73.21% (41/56) respectively before ALA-PDT, and 44.64% (25/56) and 41.07% (23/46) respectively after ALA-PDT. There were significant differences between pre- and post-treatment expression rate and intensity of VEGF and PCNA (expression rate: χ2 = 8.25, 11.81 respectively, both P < 0.05; expression intensity: H = 11.29, 12.22 respectively, both P < 0.05) . The expression of VEGF was positively correlated with the expression of PCNA in the CA tissues before and after the ALA-PDT treatment (rs = 0.202, 0.273, respectively, both P < 0.05) .@*Conclusion@#The expression of VEGF and PCNA decreased in CA tissues after ALA-PDT treatment, which may be one of the mechanisms underlying the treatment of CA with ALA-PDT.

Timing of iliac vein stenting for Cockett syndrome complicating acute lower extremity deep venous thrombosis / 中华普通外科杂志

Objective To evaluate treatment outcomes in patients with Cockett syndrome complicating acute lower extremity deep vein thrombosis (DVT) either by direct stenting after taking angioplasty followed by catheter-directed thrombolysis or staged stenting after taking angioplasty and catheterdirected thrombolysis with urokinase.Methods From Jun 2015 to Jun 2017,35 Cockett syndrome patients with DVT were divided into group A (direct stenting after taking angioplasty followed by catheterdirected thrombolysis,n =15) and group B (staged stenting after taking angioplasty and catheter-directed thrombolysis with urokinase,n =20).The total urokinase dosage,the time of thrombolysis,and the score of thrombolysis rate were evaluated.After six months of follow-up,the difference between two groups of limb circumference,patency rate and PTS rate were compared.Results The technical success rate in both group was 100％.There was no fatal pulmonary embolism and massive bleeding during the perioperative period.During treatment,both groups showed significant improvement in limb swelling compared with that before operation.The differences in the total used dosages of urokinase and thrombolysis time were not statistically significant (P =0.47,P =0.51 respectively).Thrombolysis rates above grade Ⅱ in group A and group B were 93.33％ and 90％ (P =0.64),but stent placement was not satisfactory in 2 cases in group A.After six months of follow-up,there was no significant difference between two groups of limb circumference and PTS rate,but patency rate of the two groups was 85.2％ ± 2.4％ and 87.6％ ± 1.8％ respectively (P =0.02).Conclusions For the treatment of Cockett syndrome with DVT,the timing of stent implantation does not affect thrombolytic treatment process.However,the complete removal of the iliac vein thrombosis is beneficial to precise release of the stent and the stent implantation can better maintain iliac vein lumen patency.
