Objective To investigate the effect of xuebijing injection applied after abdominal operation on the inflammatory reaction,infection rate,length of stay and hepatorenal function. Methods Sixty patients received abdominal operations were randomly divided into therapeutic group (30 cases) and control group (30 cases). The inflammatory reaction indexes (temperature,heart rate,leucocyte) and hepatorenal function indexes(aminopherase, total bilirubin, creatinine, blood urea nitrogen) were observed in both groups before operation and after operation 3,7 days respectively. The infection rate and length of stay were compared in two groups. Results Temperature and leucocyte post operative 3 days [temperature:(37.0 ± 0.2) ℃ vs. (37.9 ± 0.4) ℃ ;leucocyte: (8.8 ± 1.1 ) × 109/L vs. ( 10.3 ± 1.7) × 109/L, P＜ 0.05] and length of stay in therapeutic group was obviously better than that in control group[ (8.7 ± 1.9 ) d vs. ( 10.9±1.6) d, P ＜ 0.05 ]. The hepatorenal function indexes and infection rate in both groups had no significant difference(P ＞ 0.05). Conclusion Xuebijing injection could significantly palliate the inflammatory reaction after abdominal operation, shorten the length of stay and has no hepatorenal toxicity in short term.

Objective To study the complications related to and its management after retrieving temporary and retrievable IVC filters.Methods From Jul 2007 to Mar 2012,576 consecutive cases of deep venous thrombosis secondary to bone fractures confirmed by Duplex ultrasonography,received IVCF deployment to avoid fatal pulmonary embolism during perioperative period.There were 192 cases receiving temporary filters and 384 cases with retrievable filters.The temporary and retrievable filters were removed 2 to 4 weeks after implantation.Results The success rate of temporary filter removing was 100％.In 24 cases,the filters captured huge thrombi,and they were removed after thrombolysis using the Uni-fuse catheter.One patient received permanent filter deployment before removing the tempo-filter.Filters were successfully removed in 367 out of 384 cases with retrievable ones with a successful rate of 95.57％.In 7 cases the filters were removed with large thrombi.Double-snare-technique was used to retrieve 15 seriously tilted filters.After a mean 22 months follow-up,no pulmonary embolism occurred,but symptomatic DVT were revealed in 26 patients,and the conditions were improved after anticoagulation treatment.Conclusions The application of Uni-fuse thrombolysis catheter increases the success rate of filters retrieving,double-snare-technique helps retrieve seriously tilted filters and decrease long-term complications of permanent filters.

Objective To explore the characteristics of attenuated plaque (AP) in culprit lesions for acute coronary syndrome (ACS) in elderly patients.Methods This study included 166 ACS patients meeting the conditions from Jan.1, 2013 to Sep.31, 2014.Clinical data, vascular lesions determined by coronary angiography and intravenous ultrasound (IVUS)-demonstrated characteristics of culprit plaque, which included presence of AP, maximum attenuation arc, extravascular elastic membrane area, lumen area, plaque area, plaque burden and remodeling index, were recorded.Results Compared with non-elderly group, elderly group had a higher proportion of multiple coronary-artery lesions (50.0％ vs.35.1％, x2=6.525, P =0.038), more attenuation plaques (62.0 ％ vs.45.9％, x2 =4.245, P=0.039), a larger maximum attenuation arc[(142±80)° vs.(115±54)°, t=5.254, P=0.000], larger plaque area[(14.2±3.9)mm2 vs.(12.3 ± 4.1) mm2, t=2.325, P=0.022], more plaque burden [(81.1±14.2)％ vs.(76.4±13.5)％, t=2.025, P=0.042] and higher remodeling index [(1.19±0.17) vs.(1.09±0.13), t=4.245, P=0.031].Conclusions The onset of ACS is more closely related with the unstable plaque in elderly patients, and strengthening the measures for plaque stabilization will be helpful in the prevention and treatment of ACS in the elderly.

Objective To investigate the therapeutic effects of enhanced external counterpulsation (EECP) on cerebral edema and cerebral blood flow perfusion with MRI following cardiac arrest (CA) and on successful return of spontaneous circulation (ROSC) by cardiopulmonary resuscitation (CPR) in dogs.Methods Sixteen beagle dogs were induced CA with alternating current on epicardium,then were randomly (random number) divided into the EECP and control group after successful ROSC.MR scanning brain of all animals was carried out by diffusion-weighted imaging (DWI) and perfusion weighted imaging (PWI) before CA and on the first,second and third days after ROSC.Blood pressure,right common carotid artery flow,and intracranial microcirculation perfusion were measured.Results There were no significant differences in mean artery pressure at all intervals between two groups (P ＞ 0.05).There was significant increase in right common carotid artery blood flow and intracranial microcirculation of dogs in EECP group compared with the control group (P ＜ 0.05).Apparent diffusion coefficients (ADC) of water molecule on the first and third days after ROSC were significantly higher in the EECP group than those in the control group (P ＜ 0.05).Ratios of post-ROSC relative cerebral blood flow (RCBF) /original cerebral blood flow were higher in the EECP group than those in the control group on the first,second and third days after ROSC (P ＜ 0.05).Conclusions EECP treatment could improve cerebral blood flow perfusion and relieve ischemic cerebral edema,alleviating brain injury in dogs following CA and successful ROSC.

Objective:To investigate the computed tomography (CT) features of gastric neuroendocrine neoplasm (GNEN).Methods:The retrospective and descriptive method was conducted. The clinicopathological data of 30 GNEN patients who were admitted to two domestic medical centers (13 cases in Wenzhou Hospital of Traditional Chinese Medicine and 17 cases in Wenzhou People′s Hospital) from January 2010 to December 2018 were collected. There were 23 males and 7 females, aged (62±4)years, with a range from 27 to 78 years. The patients underwent abdominal CT plain scan and dynamic enhancement scan. Two associate chief radiologists with more than 20 years of work experience observed and analyzed all the images respectively. Observation indicators: (1) CT examination; (2) treatment and postoperative pathological examination; (3) follow-up. Follow-up was conducted using outpatient examination and telephone interview to detect the survival of patients up to December 2018. Measurement data with normal distribution were represented as Mean± SD. Measurement data with skewed distribution were described as M (range). Results:(1) CT examination: of the 30 patients, 14 had the tumor located in the fundus of stomach, 10 had the the tumor located in the body of stomach, and 6 had the tumor located in the antrum. The tumor was elliptical in 18 cases and irregular in 12 cases. There were 15 cases of endogenous type, 13 cases of exogenous type, and 2 cases of intramural type. Patients with G1 neuroendocrine tumor had the maximum diameter of (6.8±1.6)cm, of which 4 cases had the maximum diameter less than 5.0 cm and 4 cases had the maximum diameter of 5.0 to 10.0 cm. Patients with G2 neuroendocrine tumor had the maximum diameter of (8.3±2.7)cm, of which 1 case had the maximum diameter less than 5.0 cm, 4 cases had the maximum diameter of 5.0 to 10.0 cm, and 2 cases had the maximum diameter greater than 10.0 cm. Patients with G3 neuroendocrine carcinoma had the maximum diameter of (17.8±2.2)cm, of which 6 cases had the maximum diameter of 5.0 to 10.0 cm and 9 cases had the maximum diameter more than 10.0 cm. The tumor showed swelling growth in 14 cases and invasive growth in 16 cases. The tumor boundary was clear in 14 cases and unclear in 16 cases. CT plain scan showed homogeneous tumor density in 10 cases and heterogeneous density in 20 cases. Nine patients had iso-density in the tumor parenchymal part, and the CT value was (34.0±3.5)HU. In the 18 cases of low density, the CT value was (16.6±1.4)HU. In the 3 cases of high density, the CT value was (45.3±3.6)HU. Of the 30 patients, 21 cases had small punctate or small round necrotic cyst lesions in the tumor, 10 cases had mesenteric lymph node, peritoneum, liver metastasis and adjacent omentum invasion; 17 cases had abdominal effusion. In the CT enhancement examination, 12 cases showed mild enhancement, and the CT value was (56.5±6.3)HU; 15 cases showed moderate enhancement, and the CT value was (66.0±5.4)HU; 3 cases showed significant enhancement, and the CT value was (76.6±5.8)HU. Seven cases showed homogeneous enhancement and 23 cases had heterogeneous enhancement. There were 8 cases with tortuous vessels. (2) Treatment and postoperative pathological examination: of the 30 patients, 10 cases with mesenteric lymph nodes, peritoneum, liver metastasis and adjacent omentum invasion underwent radical total gastrectomy; 14 cases without surrounding tissue invasion or metastasis underwent radical subtotal gastrectomy; 6 cases with tumor diameter less than 4.0 cm and without surrounding tissue invasion or metastasis underwent endoscopic resection. All the 30 patients were confirmed GNEN by postoperative pathological examination, including 8 cases of G1 neuroendocrine tumor, 7 cases of G2 neuroendocrine tumor, and 15 cases of G3 neuroendocrine carcinoma. Results of immunohistochemical staining showed that 30 patients were positive for synaptophysin, 23 were positive for chromogranin A, and 9 were positive for cytokeratin. (3) Follow-up: all the 30 patients were followed up for 10-80 months, with a median follow-up time of 39 months. The 5-year survival rate of 30 patients was 43.3% (13/30). The 5-year survival rates were 6/8, 3/7 and 4/15 of patients with G1 neuroendocrine tumor, G2 neuroendocrine carcinoma, and G3 neuroendocrine carcinoma.Conclusions:GNEN has the main manifestation as abdominal pain, with G3 as pathological classification, which is common in fundus and body of stomach. The CT findings of GNEN are characterized by swelling or infiltrating growth and round or irregular low-density masses. Tumors are prone to cystic transformation, and showed the mildly to moderately heterogeneous enhancement.

Programmed cell death (PCD) is a genetically determined, active and orderly cell death in the organism, and it affects the evolution of the organism, maintenance of its homeostasis, and development of several tissues and organs. The abnormal regulation of this process is closely related to various human diseases, including cancer. The identified pathways of PCD include apoptosis, autophagy, necroptosis, pyroptosis, and ferroptosis, which can be activated when cells are stimulated by various internal and external environmental factors. These pathways can induce cell death or maintain cell survival in kidney cancer cells under the regulation of various signaling molecules, thus affecting tumor progression or therapeutic efficacy. In this paper, the role of these PCD pathways in the development of kidney cancer was reviewed in light of recent research advances to provide new directions for the in-depth study of the pathogenesis of kidney cancer and the development of targeted antitumor drugs.

Objective:To investigate the characteristics of computed tomography(CT) and magnetic resonance imaging(MRI)of focal peliosis hepatis (PH).Methods:From January 1, 2015 to December 31, 2022, a total of 8 PH patients (10 lesions) diagnosed pathologically in Yueqing People′s Hospital were collected. The location, size, and shape of the lesions, as well as the CT (4 patients with 4 lesions) and MRI (5 patients with 7 lesions) characteristics of the patients were analyzed. Descriptive method was used for statistical analysis.Results:Among the 8 PH patients, 6 patients had lesions located in the right lobe of the liver, 1 in the left lobe of the liver, and 1 (3 lesions) in both left and right lobes of the liver. Eight lesions were round or round-like, and 2 lesions were irregularly shaped. The median maximum diameter of the lesions was 4.2 cm (ranged from 2.2 to 9.3 cm), of which the maximum diameters of 2 lesions were less than 3.0 cm, those of 6 lesions were 3.1 to 5.0 cm, and those of 2 lesions were more than 6.0 cm. Nine lesions had clear boundaries, and 1 lesion had blurred boundary; 9 lesions had capsule, 1 lesion had no capsule; 1 lesion had blood vessels passing through it. The CT plain scan of 4 patients (4 lesions) showed that 3 lesions had uniform density and 3 lesions had low density, the CT enhancement showed that 2 lesions were significantly enhanced in the arterial phase, 3 lesions were sustained moderately enhanced in the portal phase, and 2 lesions were sustained mildly enhanced in the delayed phase. The MRI plain scan of 5 patients (7 lesions) showed uniform signals in 6 lesions, low signal in 3 lesions and equal signal in 4 lesions on T1-weighted images, high signal in 6 lesions on T2-weighted images, high signal in 3 lesions and equal signal in 4 lesions on diffusion-weighted images. The MRI enhancement showed that 4 lesions were significantly enhanced in the arterial phase, 5 lesions were sustained moderately enhanced in the portal phase, and 6 lesions showed sustained mild enhanced in the delayed phase.Conclusion:The PH lesions are round or round-like, with clear or unclear boundaries and uniform or uneven density, and are characterised by low density on CT and MRI plain scan, low signal on T1-weighted images, and high signal on T2-weighted images and diffusion-weighted images, and moderate or significant sustained enhancement on CT and MRI enhancement.

OBJECTIVETo evaluate the application of inferior vena cava filter (IVCF) in prevention of peri-operative pulmonary embolism (PE) in lower limb bone fracture patients with deep venous thrombosis (DVT).

METHODSFrom January 2003 to December 2012, 2 248 cases of lower limb and pelvic fractures with DVT were retrospectively analyzed. Before the procedure of IVCF implantation began, January 2003 to December 2007, there were 1 052 cases of acute trauma patients with DVT were classified as the group of early none-IVCF. The IVCF implantation was began since January 2008. From that time to December 2012, 712 cases of bone fractures with DVT received filter implantation, which were classified as IVCF group. The other 484 patients who had not undergone filter deployment were divided as group of late none-IVCF. The baseline conditions of the three groups were significantly different in addition to the ages between group of early none-IVCF and IVCF group. The incidences of PE and mortality of PE in each group were recorded and analyzed by χ(2) test.

RESULTSThere were totally 31 cases of symptomatic PE, among which 12 cases died. Totally 712 filters were deployed successfully without any major complications. The incidences of symptomatic PE were 0.14% (1/712), 2.19% (23/1 052) and 1.45% (7/484) in IVCF group, group of early none-IVCF and group of late none-IVCF, respectively. The mortality of PE were 0 (0/712), 0.86% (9/1 052) and 0.62% (3/484) in these groups. The incidence of symptomatic PE in IVCF group was significantly different from that in the group of early and late none-IVCF (χ(2) = 11.762, P = 0.001; χ(2) = 7.395, P = 0.007, respectively). The mortality of IVCF group was also significantly lower compared with the other two groups (χ(2) = 6.122, P = 0.013; χ(2) = 4.424, P = 0.035, respectively).

CONCLUSIONIVCF implantation effectively prevents symptomatic and fatal PE of patients of lower limb and pelvic fractures with DVT in the peri-operative period.
