Clinical characteristics of acute renal infarction: an analysis of 15 cases / 中华全科医师杂志

Clinical data of 15 patients diagnosed with acute renal infarction (ARI) in Affiliated Zhongshan Hospital of Dalian University from Jan 2011 to Dec 2021 were retrospectively analyzed. Of the included 15 patients, there were 14 cases of cardiac origin and 1 case of antiphospholipid syndrome. We found that there were 12 cases of atrial fibrillation, 2 cases of atrial premature beats, 12 cases of elevated level of D-dimer, 15 cases of elevated level of LDH, 11 cases of positive urine occult blood and positive urine protein. Among the 15 patients, catheter-directed thrombolysis was performed in 4 cases, of which 3 cases were revascularized successfully, intravenous thrombolysis in 2 cases and alone anticoagulation therapy in 9 cases. It is suggested that CECT or CTA can assist the early diagnosis of ARI especially in patients with acute onset and persistent abdominal pain with high risk factors of thromboembolism, high levels of LDH, microscopic hematuria and/or proteinuria. Despite prolonged embolic ischemia, try to reconstruct blood flow to save the kidney as much as possible. Late standardized anticoagulant therapy is of critical importance to prevent recurrent embolic episodes.

Sustained-released mixture of vascular endothelial growth factor 165 and fibrin glue strengthens healing of ileal anastomoses in a rabbit model with intraperitoneal infection

PURPOSE: To investigate the effects of a sustained-released mixture of vascular endothelial growth factor 165 (VEGF165) and fibrin glue (FG) local administration on postoperative rabbit ileal anastomoses. METHODS: One hundred twenty-eight male and female New Zealand white rabbits underwent intraperitoneal infection subsequent ileal anastomosis surgery were divided randomly into 4 groups, including 32 animals in each, applied with saline solution, FG, rhVEGF165 and a mixture of rhVEGF165 with FG (VEGF + FG) on the anastomoses, respectively. The incidences of anastomotic leakage were observed. Histopathological examination for inflammatory infiltration, fibroblast proliferation, and capillary vascular proliferation were performed. Then, bursting pressure and hydroxyproline concentrations were assessed in anastomoses sits on postoperative days 3, 5, 7, and 14. RESULTS: Rabbits in VEGF + FG group had the lowest incidence of leakage (P < 0.05). Histological evaluations revealed that granulation tissue was formed on days 5 after anastomosis; fibroblast proliferation and capillary vascular proliferation were significantly increased on days 7 and 14 in VEGF + FG group. Furthermore, there was a statistically significant difference in the mean bursting pressures between VEGF + FG group and other groups on days 7 and 14 (P < 0.05), and rabbits in VEGF + FG group exhibited a higher concentration than VEGF group (P < 0.05) and FG group (P < 0.05) on day 14. CONCLUSION: Administration of VEGF165 mixed with FG to ileal anastomosis accelerates wound healing and enhances the anastomosis by increased angiogenesis.

Treatment status of patients over 65 years old with hypertension and multimorbidity in Qinghai / 公共卫生与预防医学

Objective To investigate the treatment status of patients over 65 years old with hypertension and multimorbidity in Qinghai, so as to provide reference for clinical treatment. Methods A total of 530 patients aged over 65 years old with hypertension involved multimorbidity in Qinghai were enrolled. The main disease types and polypharmacy were analyzed. Living with Medicines Questionnaire (LMQ) was used to assess the medical burden of patients, and the potentially inappropriate medication (PIM) was measured using screening tool of older people's prescriptions (STOPP) and screening tool to alert to right treatment (START) criteria. Various indexes were analyzed, including age, gender, working status, marital status, educational level, solitary life, primary caregiver, sources of income, types of diseases, number of drugs per prescription and ways of obtaining prescriptions. The independent factors of irrational drug use in patients with hypertension and multimorbidity were discussed. Results ① Among the 530 subjects, the proportion of patients complicated with two diseases, three diseases, and four or more diseases was 71.70%, 20.00% and 8.30%, respectively. ② The top five combination types of multimorbidity were hypertension with coronary heart disease (26.04%), hypertension with dyslipidemia (16.04%), hypertension with diabetes (13.02%), hypertension with coronary heart disease and dyslipidemia (7.55%), hypertension with coronary heart disease and diabetes (3.96%).③ The types of drugs per prescription ranged from 1 to 11, with an average of 6.13 types, and the multiple medication rate reached 83.02% (440/530). ④ LMQ scale indicated that drug burden of patients with multimorbidity was at moderate to severe degree. ⑤ Taking STOPP/START as standard, the incidence of PIM was 32.64%.⑥ Multivariate Logistic regression analysis showed that education level and prescription obtained from secondary or above level hospitals were protective factors for PIM in patients with hypertension and multiple diseases, while the type of medication was a risk factor for PIM. Conclusion The elderly patients with hypertension and multiple diseases in Qinghai have a high multiple medication rate, and are in a state of moderate to severe drug burden, moreover, the PIM rate is also relatively high, so clinical standardization of drug use and reduction of drug burden are of vital importance.

Protective effects of Dahuangfuzi decoction on the intestine barrier functional of acute necrotizing pancreatitis in rats / 中华胰腺病杂志

Objective To observe the effects of Dahuangfuzi decoction on the intestine barrier functional of acute necrotizing pancreatitis in rats. Methods The 60 rats were randomly divided into sham operation group ( n = 19 ), ANP group ( n = 21 ), and Dahuangfuzi treatment group ( n = 20). The rats of ANP group were induced by injecting 1 ml/kg of 4% sodium taurocholate into the pancreatiobiliary duct, and jejunal fistula was esablished. The rats of treatment group received Dahuangfuzi decoction (2 ml, repeated at 4 and 8 h)through jejunum distal stoma tube 0. 5 h after ANP induction. The other 2 groups received same amount of normal saline. Blood sample was collected through abdominal aorta, 24 h after ANP induction, and the serum amylase, endotoxin, D-lactate, plasma diamine oxidase (DAO) were detected. Pancreas, small intestine tissue was harvested for pathologic examination, index of intestinal epithelial damage was measured and ultrastructural changes in small intestinal mucosa was observed. Results The expression of serum amylase, endotoxin,D-lactate, DAO in sham operation group was ( 152 ± 32 ) U/L, (6.95 ± 2.10) pg/L, ( 3.96 ± 1.08 ) μg/mland ( 14.26 ± 2.67 ) μg/ml, while the corresponding values were ( 1549 ± 93 ) U/L, (40.48 ± 3.41 ) pg/L,( 12.34 ± 1.23 ) μg/ml and ( 80.28 ± 3.54) μg/ml in ANP group, and they were (655 ± 49 ) U/L, ( 19.55 ±2.50) pg/L, (6.75 ± 1.36 ) μg/mland ( 20.69 ± 7.53 ) μg/ml in treatment group. The values in ANP group were significantly higher than those in sham operation group. The values in treatment group were significantly lower than those in ANP group, but significantly higher than those in sham operation group ( P ＜ 0.05 or P ＜0. 01 ). The thickness and height of intestinal mucosa in ANP group were ( 389.44 ± 29.87 )μm and ( 16.52 ±3.73) μm, which were significantly lower than those in treatment group [(501.95 ± 45.38 )μm, (27.82 ±5.17)] μm, and in sham operation group [( 658.72 ± 57.49 ) μm, ( 35.49 ± 6.43 )μm, Index of intestional epitholial donage in ANP group was 3.72 ± 0.65 which is significently higher than those in theatment (2.12 ±0.37 ) and in sham operation group (0.85 ± 0.24). The intestinal mucosa histological and ultrastructural changes in Dahuangfuzi treatment group were better than those in ANP group. Conclusions Dahuangfuzidecoction can significantly decrease the damage of intestine barrier function in ANP rats.

Minimally invasive perventricular vsd closure without cardiopulmonary bypass mid-term results from multi-centers / 中华胸心血管外科杂志

Objective Transesophageal echocardiography (TEE) guided, minimally invasive perventricular device occlusion of ventricular septal defects ( VSDs) without cardiopulmonary bypass ( CPB) has been applied in multiple centers. We reported experiences and the mid-term results. Methods Four hundred and thirty-two cases from 4 cardiac centers were involved in the study. There were 235 males and 197 females, aged from 3 months to 15 years, with a body weight varying from 4.0 to 26.0 kg. Three hundred and fifty-one patients had perimembranous VSDs, 57 had intracristal or supracristal VSDs and 24 had muscular VSDs (17 had multiple muscular VSDs). The diameter of the VSD ranged from 3 to 12 (5.3 ±1.6 ) mm.For those with perimembranous or muscular VSDs, a 3 to 5 cm inferior sternotomy was made, but for those with intracristal or supracristal VSDs, a 2 to 3 cm incision was made parastemally through the left third intercostal space. Being monitored and guided with TEE, the device was deployed to occlude the VSD through the puncture at the free wall of the right ventricle. TEE was used for assessing the residual shunting, the left and right ventricular outlet tracts, valvular function and for detecting any arrhythmia, The devices would be released if the heart rhythm was normal, as well as the residual shunting and valvular regurgilalion were not detected. Results The procedure was completed successfully in 417 cases(96.5% ) and converted to traditional surgical closure with CPB in the other 15 cases(3.5% ). Concentric devices were used in 238 cases(57.1% )and eccentric devices were used in 179 patients(42.9% ). Successful procedures finished in less than 90 minutes, and the deployment and evaluation of the devices were completed in 5 to 60 (18. 2 ± 8.6) minutes. No residual shunt and detectable aortic or tricuspid insufficiency and arrhythmia was observed. Patients were extubated within 2 hours and discharged 3 to 5 days after the operation. During fellow-up period from 3 months to 2 years, no clinically significant complications occurred. Conclusion The minimally invasive device closure of VSD under TEE guidance without CPB is proved to be a simple, safe and effective treatment for a considerable number of children with VSD. Its use in the clinical practice should be encouraged.

Effect of Dahuang Fuzi decoction on alveolaur epithelial barrier in rats with lung injury with severe acute pancreatitis / 中华急诊医学杂志

Objective To investigate effect of Dahuang Fuzi decoction on alveolaur epithelial barrier in rats with lung injury with severe acute pancreatitis. Method Ninty-six health SD rats were randomly divided into three groups: sham operation group, SAP-ALI group, Dahuang Fuzi decoction group, and then according to the time point of sacrifice after operation, each group was subdivided into 3,6,12,24 hour subsets ( each, n = 8). After the belly of a rat in the sham operation group was cut open, the pancreas was flipped several times,and then a stoma was made in the jejunum to form its fistula. In the SAP-ALl group,1 mL/kg sodium taurocholate was reversely injected into the pancreatobile duct to establish the model of SAP, and then the jejimum fistula was performed. The SAP-ALI model in Dahuang Fuzi decoction group was treated by injection of 10ml of Dahuang Fuzi decoctionon into the fistula respectively. Blood was collected from heart to detect serum amvlase and endotoxin (ET) levels before the rat being executed. The lung histopathologic changes, pulmonary injury scores and wet/dry weight(W/D) ratios were observed after the rats were executed. The alveolar liquid clearance rate(ALCR), total lung water content (TLW), extravascular lung water content(EVLW) and alveolar epithelial permeability (AEP) were examined in 3,6, 12,24 h after injury.Results There was continuous increase of AEP,TLW and EVLW,as well as progressive reduction of ALCR compared with sham operation group at 3,6,12,24 h after operation. Compared with SAP-ALI group, there was continuous decrease of AEP,TLW and EVLW, and elevated of ALCR at 3,6,12,24 h after operation.Conclusions Dahuang Fuzi decoction can significantly reduce alveolaur epithelial barrier and degree of lung tissue of SAP-ALI rats by inhibiting the elevation of LPS and inflammation reaction.
