ABSTRACT

Objective To explore the optimal parameters for virtual mono-energetic imaging of liver solid lesions. Methods A retrospective analysis was performed on 60 patients undergoing contrast-enhanced spectral CT of the abdomen.The iodine concentration values of hepatic arterial phase images and the CT values of different mono-energetic images were measured.The correlation coefficient and coefficient of variation were calculated. Results The average correlation coefficients between iodine concentrations and CT values of hepatic solid lesion images at 40,45,50,55,60,65,and 70 keV were 0.996,0.995,0.993,0.989,0.978,0.970,and 0.961,respectively.The correlation coefficients at 40(P=0.007),45(P=0.022),50 keV (P=0.035)were higher than that at 55 keV,and the correlation coefficients at 40 keV(P=0.134) and 45 keV(P=0.368) had no significant differences from that at 50 keV.The coefficients of variation of the CT values at 40,45,and 50 keV were 0.146,0.154,and 0.163,respectively. Conclusion The energy of 40 keV is optimal for virtual mono-energetic imaging of liver solid lesions in the late arterial phase,which is helpful for the diagnosis of liver diseases.

ABSTRACT

Objective To explore the therapeutic effects of estrogen-intervened endothelial progenitor cells( EPCs) transplantation on diabetic ischemic stroke rats. Methods PKH26-labeled diabetic EPCs and estrogen-intervened diabetic EPCs were injected into rats via the tail vein 24 h after cerebral ischemia. Cerebral ischemic volume, behavioral changes, ischemic site vascularization and homing of EPCs were measured 3 d after EPCs injection. Results Compared with diabetic ischemic rats, estrogen-intervened EPCs transplantation had reduced infarct volumes, improved behavioral scores and ischemic site revascularization and promoted homing of EPCs to sites of injury(P<0.05). Conclusion Estrogen-intervened EPCs transplantation had a better therapeutic effect on diabetic ischemic stroke by promoting EPCs homing to injury site and EPCs-medicated neovascularization .

ABSTRACT

Objective:To establish a nomogram based on features under endoscopic ultrasonography (EUS) for predicting the diagnosis of small gastric stromal tumors.Methods:The clinicopathological data of 189 patients with gastric submucosal tumors (diameter less than 2 cm) who underwent endoscopic resection at the Department of Gastroenterology, Tongji Hospital of Tongji University from June 2015 to August 2021 were retrospectively collected. All patients were divided into the modeling group ( n=126) and the validation group ( n=63) at 2∶1 by random function of software R. Independent influencing factors for the diagnosis of small gastric stromal tumors under EUS screened by univariable and multivariable logistic regression analysis were used to establish the diagnostic prediction nomogram. The receiver operator characteristic (ROC) curves were drawn to evaluate the discrimination of the model both in the modeling group and the validation group. Hosmer-Lemeshow test and calibration curve were used to evaluate the calibration of the model in both groups. Results:The age of patients >60 years ( OR=2.815, 95% CI:1.148-6.900, P=0.024), the lesions located in cardia/fundus ( OR=5.210, 95% CI:1.225-22.165, P=0.025), originated in muscularis propria ( OR=6.404, 95% CI:2.262-18.135, P<0.001) and of external growth ( OR=6.024, 95% CI:1.252-28.971, P=0.025) were independent influencing factors for the diagnosis of small gastric stromal tumors under EUS. The diagnostic prediction nomogram was established based on the four factors above. The areas under ROC curve of the modeling group and validation group were 0.834 (95% CI:0.765-0.903) and 0.780 (95% CI:0.667-0.893). Hosmer-Lemeshow test indicated that this model fit the data well ( χ2=10.23, P=0.176 in the modeling group; χ2=2.62, P=0.918 in the validation group). Calibration charts of the model drawn by Bootstrap method showed that the calibration curves fit well with the standard curves in both groups. Conclusion:The nomogram based on features under EUS for predicting the diagnosis of small gastric stromal tumors provides a visual reference for endoscopists to diagnose small gastric stromal tumors under EUS with good discrimination and calibration.

ABSTRACT

Objective:To analyze the clinical efficacy and prognostic factors of intracranial primary diffuse large B-cell lymphoma (DLBCL).Methods:Clinical data of 205 patients pathologically diagnosed with intracranial primary DLBCL at Sun Yat-sen University Cancer center from March 2001 to September 2020 were retrospectively analyzed. Among them, 101 patients were male and 104 female, the median age was 54 years old. Non-germinal center B cell (GCB) subtype accounted for 74.1%(126/170). A total of 177 patients received high-dose methotrexate (HD-MTX) and 91 patients received rituximab. After induction chemotherapy, 59 patients (30.4%) achieved complete response (CR), 112 patients (57.7%) achieved partial response (PR) or stable disease (SD). A total of 83 patients received consolidation or salvage radiotherapy, and only 14 patients received autologous stem cell transplantation (ASCT). The influence of pathological type, chemotherapy, rituximab treatment, radiotherapy and radiotherapy mode, ASCT and other factors on the overall survival (OS) and progression free survival (PFS) was evaluated. The survival rate was calculated by Kaplan-Meier method. Univariate prognostic analysis was performed by log-rank test. Multivariate prognostic analysis was conducted by COX model.Results:The median follow-up time was 34 months. The 5-year OS and PFS rates were 55.6% and 44.2%, respectively. GCB subtype, chemotherapy with HD-MTX, rituximab treatment, remission status after induction chemotherapy, and radiotherapy were favorable prognostic factors for OS or PFS, in which the last three were the independent prognostic factors. Consolidation radiotherapy in patients who obtained CR after induction chemotherapy did not significantly improve survival, while salvage radiotherapy in patients who achieved PR/SD after induction chemotherapy significantly improved both OS and PFS(both P<0.01). Consolidation radiotherapy showed no significant survival difference compared with consolidation ASCT. Conclusions:The non-GCB subtype of intracranial primary DLBCL is related to poor prognosis. The addition of rituximab to HD-MTX based induction chemotherapy can improve survival. Radiotherapy is still an important treatment for intracranial primary DLBCL, and there are limitations of ASCT in practical clinical application.

ABSTRACT

Objective: To analyze the serum carbohydrate antigen 125 (CA125) level and its influencing factors in male silicosis patients with pulmonary heart disease. Methods: In October 2021, data of 38 male patients with simple silicosis (silicosis group), 28 cases of silicosis with pulmonary heart disease (pulmonary heart disease group), and 27 healthy controls (control group) in the same age group were collected in inpatient and outpatient of Nanjing Occupational Disease Prevention and Control Hospital from January 2017 to December 2020. The serum CA125 levels of the three groups were compared, and the correlation between disease-related indexes and serum CA125 in silicosis patients with pulmonary heart disease was analyzed, as well as the influencing factors of pulmonary heart disease and serum CA125 levels in silicosis patients. Results: The serum CA125 level[ (19.95±7.52) IU/ml] in pulmonary heart disease group was higher than that in silicosis group[ (12.98±6.35) IU/ml] and control group[ (9.17±5.32) IU/ml] (P<0.05). There was no significant difference in serum CA125 level between the silicosis group and the control group (P>0.05). Serum CA125 levels were positively correlated with blood uric acid and fasting blood glucose in silicosis patients with pulmonary heart disease (r=0.39, 0.46, P<0.05). Serum CA125 level was a risk factor for silicosis patients with pulmonary heart disease (OR=1.13, 95%CI: 1.02-1.24, P<0.05). Dust exposure time, lactate dehydrogenase and smoking history were positively correlated with serum CA125 level in silicosis patients (P<0.05) . Conclusion: The serum CA125 level of male silicosis patients with pulmonary heart disease is significantly increased, and the level of CA125 is correlated with the level of fasting blood glucose and blood uric acid.

ABSTRACT

Accumulating evidence has confirmed the links between transfer RNA (tRNA) modifications and tumor progression. The present study is the first to explore the role of tRNA methyltransferase 5 (TRMT5), which catalyzes the m1G37 modification of mitochondrial tRNAs in hepatocellular carcinoma (HCC) progression. Here, based on bioinformatics and clinical analyses, we identified that TRMT5 expression was upregulated in HCC, which correlated with poor prognosis. Silencing TRMT5 attenuated HCC proliferation and metastasis both in vivo and in vitro, which may be partially explained by declined extracellular acidification rate (ECAR) and oxygen consumption rate (OCR). Mechanistically, we discovered that knockdown of TRMT5 inactivated the hypoxia-inducible factor-1 (HIF-1) signaling pathway by preventing HIF-1α stability through the enhancement of cellular oxygen content. Moreover, our data indicated that inhibition of TRMT5 sensitized HCC to doxorubicin by adjusting HIF-‍1α. In conclusion, our study revealed that targeting TRMT5 could inhibit HCC progression and increase the susceptibility of tumor cells to chemotherapy drugs. Thus, TRMT5 might be a carcinogenesis candidate gene that could serve as a potential target for HCC therapy.

ABSTRACT

OBJECTIVE@#To evaluate the effectiveness of different screening strategies for type 2 diabetes to prevent cardiovascular disease in a community-based Chinese population from economically developed areas based on the Chinese electronic health records research in Yinzhou (CHERRY) study.@*METHODS@#A Markov model was used to simulate different systematic diabetes screening strategies, including: (1) screening among Chinese adults aged 40-70 years recommended by the 2020 Chinese Guideline for the prevention and Treatment of Type 2 Diabetes (Strategy 1); (2) screening among Chinese adults aged 35 to 70 years recommended by the 2022 American Diabetes Association Standard of Medical Care in Diabetes (Strategy 2); and (3) screening among Chinese adults aged 35-70 years with overweight or obesity recommended by the 2021 United States Preventive Services Task Force Recommendation Statement on Screening for Prediabetes and Type 2 Diabetes (Strategy 3). According to the guidelines, individuals who were screened positively (fasting plasma glucose ≥ 7.0 mmol/L) would be introduced to intensive glycemic targets management (glycated hemoglobin < 7.0%).The Markov model simulated different screening scenarios for ten years (cycles) with parameters mainly from the CHERRY study or published literature. Number of cardiovascular disease events or deaths could be prevented and number needed to screen (NNS) were calculated to compare the effectiveness of the different strategies. One-way sensitivity analysis on the sensitivity of screening methods and probabilistic sensitivity analysis on uncertainties of diabetes incidence, the sensitivity of screening methods, and intensive glycemic management effects were conducted.@*RESULTS@#Totally 289 245 Chinese adults aged 35-70 years without cardiovascular diseases or diagnosed diabetes at baseline were enrolled. In terms of the number of cardiovascular disease events could be prevented, Strategy 1 for systematic diabetes screening among the adults aged 35-70 years was 222 (95%UI: 180-264), Strategy 2 for systematic diabetes screening among the adults aged 40-70 years was 227 (95%UI: 185-271), and Strategy 3 for systematic diabetes screening among the adults aged 35-70 years with obesity or overweight (body mass index ≥ 24 kg/m2) was 131 (95%UI: 98-164), compared with opportunistic screening. NNS per cardiovascular disease event for the strategies 1, 2 and 3 were 1 184 (95%UI: 994-1 456), 1 274 (95%UI: 1 067-1 564) and 814 (95%UI: 649-1 091), respectively. Compared with Strategy 1, NNS per cardiovascular disease event for Strategy 2 increased by 90 (95%UI: -197-381) with similar effectiveness of cardiovascular prevention; however, NNS per cardiovascular disease event for Strategy 3 was reduced by 460 (95%UI: 185-724) in contrast to the Strategy 2, suggesting that the Strategy 3 was more efficient. The results were consistent in multiple sensitivity analyses.@*CONCLUSION@#Systematic screening for diabetes based on the latest guidelines in economically developed areas of China can reduce cardiovascular events and deaths. However, merely lowering the starting age of screening from 40 to 35 years seems ineffective for preventing cardiovascular disease, while screening strategy for Chinese adults aged 35-70 years with overweight or obesity is recommended to improve efficiency.

ABSTRACT

Objective:To explore the clinical effects of combined medial and lateral approaches in treating of calcaneal fractures combined with sustentaculum tali fractures and/or dislocations of sustentaculum tali-talus joint.Methods:Four adult cadaver specimens (8 feet) were selected, of which two (4 feet) were dissected on the medial side of the calcaneus to observe the adjacency and exposure range of sustentaculum tali. The other two specimens were simulated as medial and lateral approaches to reduce and fix calcaneal fractures. Retrospective analysis of 9 cases (9 feet) of Sanders II-IV type calcaneal fractures with combined medial and lateral approaches in the treatment of fractures and/or dislocations of sustentaculum tali-talus joint was performed. The average age was 49.9±11.3 (25-58) years. During the operation, the medial incision was made first, and the sustentaculum tali fracture was temporarily reduced and fixed to the talus. Then the lateral incision was made to expose the lateral side of the calcaneus, and the fracture fragments were reduced and fixed; the sustentaculum tali was fixed laterally with screws, and 2 cases were additionally fixed medially with absorbable rods. At the same time, six cases (8 feet) of calcaneal fractures with sustentaculum tali fractures and/or dislocations of sustentaculum tali-talus were treated with lateral approach as a control group. The lateral sides of both groups were fixed with calcaneal locking plate and implanted with demineralized bone matrix into the cavity after articular surface reduction. The B?hler and Gissane angles of the two groups of patients were measured at 1 year after operation. The American Orthopaedic Foot and Ankle Society (AOFAS) scoring system was used to evaluate the clinical efficacy.Results:The sustentaculum tali-talus joint had a shape of an inverted "V" with two divided parts. The tip of the sustentaculum tali was exposed through the front window of the posterior tibial tendon. The sustentaculum tali and the medial side of the calcaneal body was completely exposed and fixed through the window between the posterior tibial tendon and the flexor digitorum longus tendon. The postoperative incision blood loss in the combined medial and lateral approach group was 73.6±4.3 ml, which was greater than that in the lateral approach group (70.6±7.1 ml) ( t=2.18, P=0.045). The lateral incision healed in both groups. The medial incision healed delayed in 1 patient in the combined medial and lateral approach group. The fractures in the combined medial-lateral approach group and the lateral approach group were both healed. The healing duration was 12.2±2.1 weeks and 12.8±2.8 weeks, respectively, without significant difference ( t=0.50, P=0.622). The B?hler angles of the combined medial-lateral approach group and the lateral approach group were 37.0°±5.7° and 27.9°±4.0° at 1 year after operation, respectively. These values were greater than the preoperative values of 4.7°±3.4° and 3.9°±2.9° ( P<0.05), with significant difference between groups ( t=3.76, P=0.002). The Gissane angles were 133.2°±9.8° and 139.1°±9.4° respectively, which were lower than those of 172°±7.3° and 175.6°±5.6° before operation ( P<0.05). There was no significant difference between the groups ( t=1.26, P=0.226). The AOFAS score of the combined medial and lateral approach group was 93.6±4.0 points, which was higher than that of the lateral approach group (84.3±8.2 points) ( t=3.03, P=0.008). Conclusion:Intra-articular calcaneal fractures combined with a high probability of sustentaculum tali fractures and/or dislocations of sustentaculum tali-talus joint. Compared with the simple lateral approach, the use of the combined medial-lateral approach and the medial-lateral surgical sequence is beneficial to restore the calcaneal alignment and anatomic shape, especially the alignment relationship of the medial calcaneus and talus, so as to obstain better early clinical outcomes.

ABSTRACT

Objective:To investigate the diagnostic value and imaging characteristics of ultrasound and multi-slice spiral CT in rheumatoid arthritis (RA) wrist joint lesions.Methods:The clinical data of 54 cases of RA wrist arthropathy in Jianhu Hospital Affiliated to Nantong University from December 2018 to April 2020 were analyzed. All the patients were examined by ultrasound and multi-slice spiral CT. The imaging characteristics of ultrasound and multi-slice spiral CT were analyzed, and the detection rates of synovitis, joint effusion, tenosynovitis, bone erosion and wrist joint lesions were calculated.Results:A total of 1 188 joints were examined in 54 patients with RA, including 108 wrist joints, 540 metacarpophalangeal joints and 540 proximal interphalangeal joints. There was no significant difference in the detection rate of wrist joint synovitis, joint effusion and tenosynovitis between ultrasound and CT ( P>0.05). The wrist joint lesions detection rates of ultrasound and CT were 97.2%(105/108) and 46.3% (50/108), the difference was statistically significant ( χ2 = 36.52, P<0.05). Ultrasound image features: synovitis ultrasound image showed hypoechoic joint cavity, not by joint displacement or compression image, color Doppler flow imaging (CDFI) examination could see blood flow signal;joint effusion in ultrasound image of joint effusion was strip, strip-shaped, non-uniform distribution, image was affected by joint displacement or compression, CDFI examination had no blood flow signal; bone erosion ultrasound image showed bone cortical continuous interruption or "crater" "insect erosion" like defects. CT imaging features: wrist joint space narrow, osteoporosis, some patients with scaphoid, distal radius visible bone erosion. Conclusions:The detection rate of wrist synovitis, joint effusion and tenosynovitis by ultrasound and multi-row spiral CT are similar. The multi-row spiral CT examination have a slight advantage in evaluating the joint space and bone changes. The sensitivity of wrist bone erosion and wrist joint lesions are higher than those of multi-row spiral CT, which can guide the early clinical diagnosis and treatment of RA.

ABSTRACT

Objective:To analyze the clinical effects of fecal microbiota transplantation (FMT) on the treatment of acute intestinal pseudo obstruction (AIPO) secondary to intracerebral hemorrhage.Methods:The clinical data of a patient with AIPO secondary to intracerebral hemorrhage who was admitted to Nanfang Hospital of Southern Medical University was analyzed. The flora compositon between donor and patient was compared, finding the changes of intestinal flora before and after FMT (day 0 and day 25).Results:The main clinical findings in the patient were serious bloating, expansion of the intestinal canal and intra-abdominal hypertension. A week of conventional therapy was not effective, and the symptoms became progressively worse, affecting respiratory function.The result of fecal flora suggested the intestinal microbiota dybiosis, so FMT was attempted. After FMT, the patient's gastrointestinal symptoms were significantly relieved, and there were no further episodes within 25 days. The new result of fecal flora showed that the flora colonizing the intestine was dominated by Akkermansia and Bifidobacterium, with a significant decrease in potential pro-inflammatory and gas-producing bacteria and an increased gut microbiota diversity. The results trended to be partly consistent with the donor at 25 days after FMT: at the phylum level, the relative abundance of Bacterioidetes, Vereucomicrobia, Firmicutes and Actinobacteria were increased while Proteobacteria was decreased; at the class level, the relative abundance of Verrucomicrobiae, Bacterioidia, Actinobacteria, Coriobacteriia and Clostridia were increased and Gammaproteobacteria was decreased; at the order level, the relative abundance of Bacterioidales, Verrucomicrobiales, Clostridiale, Coriobacteriales were increased and Betaproteobacteriales, Enterobacteriales were decreased; at the family level, the relative abundance of Bifidobacteriaceae, Akkermansiaceae, Ruminococcaceae were increased and Enterobacteriaceae was decreased; at the genus level, the relative abundance of Akkermansia, Bifidobacterium were increased and Escherichia-Shigella, Klebsiella were decreased. At 1-year follow-up, the patient lived with self-care and scored 5 points in Glasgow outcome scale (GOS). Conclusions:FMT may provide clinical benefit in treated patients with AIPO secondary to intracerebral hemorrhage, probably by regulating the intestinal microflora, and re-establishing proper intestinal barrier, to maintain intestinal homeostasis.

ABSTRACT

Objective:To determine the seroprevalence of celiac disease in susceptible population, and to analyze the relationship between demographic characteristics, dietary habits, lifestyle and serological positivity so as to provide guidance for the prevention and treatment of celiac disease in Southern China.Methods:A total of 1 273 individuals who participated in Guangdong Province Health Screening Program in 2015, were selected as serologically positive subjects of celiac disease, including people with irritable bowel syndrome, colitis, diarrhea, anemia, low BMI, short stature, type 1 diabetes mellitus (T1DM), rheumatoid arthritis (RA), ankylosing spondylitis, psoriasis and bristol grade=6 or 7. All subjects were tested for serum IgA anti-tissue transglutaminase antibodies (TTGA), IgA antibodies against deamidated gliadin peptides(DGPA) and IgG against deamidated gliadin peptides (DGPG). Dietary habits, lifestyle and demographic characteristics were compared in subgroups.Results:The seroprevalence of celiac disease in susceptible population was 0.94% (95% CI 0.54%-1.64%) including 0.08% (1/1 273) for TTGA, 0.47% (6/1 273) for DGPA, and 0.39% (5/1 273) for DGPG. The seropositive rate was 3.6% (1/28) in patients with psoriasis, 2.1% (2/95) in the low BMI group, 1.9% (1/53) in T1DM group, 1.8% (3/169) in diarrhea group and 1.1% (5/463) in RA group. No significant difference was found in age, gender, high carbohydrate diet or lifestyle between the negative and the positive subjects. Conclusions:In Southern China, the seropositive rate of celiac disease is 0.94% in susceptible population, which prompts an urgent need of serological screening for early diagnosis.

ABSTRACT

Objective:To summarize the clinical features, genetic testing and treatment efficacy of 6 children with Dent disease.Methods:Six children diagnosed with Dent disease in Guangzhou Women and Children′s Medical Center from January 2014 to March 2019 were enrolled.Their medical history, clinical manifestations, laboratory results, genetic test results, and proteinuria level, calciuria level and renal function after medication were measured.Results:All patients were male, with the onset age ranged from 1 to 9 years old.They were followed up for 6 months to 4 years.All the children had low molecular weight proteinuria.Urine protein electrophoresis showed that the ratio of low molecular weight proteinuria in only 2 cases was more than 50%.Renal biopsy suggested that all cases were combined with glomerular lesions.Five cases had hypercalciuria.Under the microscope, there were 5 cases of hematuria.Two case had rickets, and there was no renal calcium deposition and hypophosphatemia.Five cases were detected with CLCN5 mutations, of which p. C160Yfs*49 and p. G523D were first reported.One case had an OCRL1 mutation.Patients were treated with Hydrochlorothiazide and angiotensin converting enzyme inhibitor (ACEI). The 24 h urinary calcium level after treatment was lower than that before treatment [0.40 (0.24, 0.43) mmol/kg vs.0.12 (0.11, 0.14) mmol/kg, U=2.00, P<0.01]. However, there was no significant decrease in the 24 h-urinary protein level before and after treatment [77.09 (62.41, 88.01) mg/kg vs.80.33 (66.03, 92.52) mg/kg, U=12.00, P>0.05]. Conclusions:Dent disease is mainly characterized by low molecular weight proteinuria, and some patients may not be associated with hypercalciuria.Gene tests help to identify the disease type.ACEI and Hydrochlorothiazide can reduce the urinary calcium level, but cannot improve the level of urinary protein.

ABSTRACT

Objective:To evaluate the efficacy of Paishi decoction in ureteral calculi treatment. Methods:Ureteral calculi patients were voluntarily divided into two groups in Shanghai Baoshan Traditional Chinese Medicine-Integrated Hospital. Patients in the control group received anti-inflammatory symptomatic treatment for 2 weeks, and patients in the treatment group received anti-inflammatory symptomatic treatment combined with Paishi decoction for 2 weeks. Results:There was no significant difference between the two groups in gender, age, body weight and stone size. Compared with the control group, after taking Paishi decoction for 2 weeks, the urinary oxalic acid and calcium in the treatment group decreased significantly, and the urine citric acid increased (P<0.05). The difference in clinical effective rate was significant between the two groups (P<0.05). Conclusion:Paishi decoction is superior to single anti-inflammatory symptomatic treatment in the treatment of ureteral calculi, which reflects the advantages of integrated traditional Chinese and Western medicine. However, the number of patients included in this study was limited, further studies are in need to verify the result.

ABSTRACT

Background/Aims@#Risk of venous thrombosis is increased in patients with inflammatory bowel disease (IBD); data on Asian IBD patients is limited and status quo of thrombosis screening and prophylaxis are unknown. Therefore, we aimed to investigate the incidence, screening, prophylaxis, and risk factors for venous thrombosis among Asian IBD patients. @*Methods@#Medical files of patients with Crohn’s disease (CD) and ulcerative colitis (UC) from 17 hospitals across China between 2011 and 2016 were reviewed for venous thrombosis, use of screening and prophylaxis. A case-control study was performed among hospitalized patients with venous thrombosis and their age-, sex-matched IBD controls hospitalized around the same period; disease characteristics and known provoking factors of venous thrombosis were recorded. Risk factors were analyzed in both univariate and logistic regression analyses. @*Results@#A total of 8,459 IBD patients were followed for 12,373 person-year. Forty-six patients (0.54%) had venous thrombosis, yielding an incidence of 37.18 per 10,000 person-year. Incidence increased with age, especially among CD. Less than 20% of patients received screening tests and 35 patients (0.41%) received prophylaxis. Severe disease flare was an independent risk factor for venous thrombosis (odds ratio [95% confidence interval]: CD, 9.342 [1.813– 48.137]; UC, 5.198 [1.268–21.305]); past use of steroids and extensive involvement were 2 additional risk factors in CD and UC, respectively. @*Conclusions@#Incidence of venous thrombosis in China was 37.18 per 10,000 person-year (0.54%). Use of screening and prophylaxis were rare. Severe disease flare was an independent risk factor for thrombosis among hospitalized patients.

ABSTRACT

Objective:To explore the effect and mechanism of Guizhitang with different proportions of Cinnamomi Ramulus and Paeoniae Alba Radix on overactive cardiac sympathetic nerves in salt-sensitive hypertensive rats. Method:Randomly divide the forty male 6-week-old salt-sensitive hypertensive rats into five groups: the normal control group, the model group, the Cinnamomi Ramulus and Paeoniae Alba Radix 1∶1 group, the Cinnamomi Ramulus and Paeoniae Alba Radix 1∶2 group,and the Cinnamomi Ramulus and Paeoniae Alba Radix 2∶1 group, each group has 8 animals, the normal control group was fed with low-salt feed, and the remaining four groups were fed with 8% high-salt feed. After 4 weeks of feeding, gastric feeding was started. Give both the normal control group and model group saline and the Cinnamomi Ramulus and Paeoniae Alba Radix 1∶1 group, the 1∶2 group,and the 2∶1 group, were given Guizhitang aqueous solution at 4.0, 5.5 and 5.5 g·kg-1, respectively. Continuous gavage intervention was held for 4 weeks. IITC multi-channel non-invasive sphygmomanometer was used to detect changes of systolic blood pressure before and after treatment in rats. Left ventricular anterior wall end-diastolic thickness (LVAWd) and interventricular septal diastolic thickness (IVSd) were detected by echocardiography. Hematoxylin-eosin(HE)staining and Masson staining were used to observe the myocardial morphological changes of rats in each group, Western blot was used to detect the expression of nerve growth factor (NGF), growth-associated protein 43 (GAP43) and tyrosine hydroxylase (TH) protein. Result:After 4 weeks of intervention with Guizhitang, compared with the normal control group, the blood pressure, LVAWd and IVSd of the model group were significantly increased, and the expressions of NGF, TH and GAP43 protein were significantly increased (P<0.01). HE and Masson staining results showed that the model group had myocardial cell edema, a large number of inflammatory cell infiltration, myocardial fiber hyperplasia and disordered arrangement, and a large amount of collagen deposition could be seen in the intercellular substance. Compared with model group, the systolic blood pressure of rats in each Guizhitang group increased slowly, and the expression of NGF, TH and GAP43 protein decreased (P<0.05,P<0.01),the Cinnamomi Ramulus and Paeoniae Alba Radix 1∶1 group has the best effect. The results of echocardiography shows that the 1∶1 Guishao group could reduce LVAWd and IVSd levels (P<0.05,P<0.01), the Cinnamomi Ramulus and Paeoniae Alba Radix 1∶2 group could reduce IVSd level (P<0.05), there was no statistical difference in LVAWd, there was no statistical difference in LVAWd and IVSd in 2∶1 group. In terms of myocardial morphology, each group of Guizhitang can reduce cell edema and inflammatory cell infiltration, reduce myocardial fiber hyperplasia and collagen deposition, and improve the disorder of myocardial fiber arrangement. Among them, the 1∶1 group has the best effect. Conclusion:Guizhitang can inhibit the overactive activation of cardiac sympathetic nervous system,reduce the extent of myocardial fibrosis, inflammatory infiltration and myocardial hypertrophy, and protect salt-sensitive hypertension rats, whose mechanism may be related to regulating the expression of heart NGF.Among them, the Cinnamomi Ramulus and Paeoniae Alba Radix 1∶1 group is better than the 1∶2 and 2∶1 group in reducing myocardial fibrosis, inflammatory infiltration and myocardial hypertrophy.
