AIM: To investigate the antitumor and synergistic effect of Chinese medicine “Bushen huayu jiedu recipe” (recipe for invigorating the kidney, removing blood stasis and toxic substances) and chemotherapy on mice hepatocarcinoma. METHODS: Bushen huayu jiedu recipe (BSHYJDR) consisting of Chinese Cassia Bark, Psoralea, Zedoary, Rhubarb, etc. is equal to 1.5 g/mL liquid of originated herbs after being decoded, filtered, and concentrated. Kunming mice, weighing 18-22 g, were injected with 0.2 mL ascitic hepatocarcinoma H22 containing 1 × 10^7 cells/mL into armpit of the right forelimb of mice. After 24 h, the mice were weighed and randomly divided into tumor-bearing model control group, cisplatin (DDP) group, BSHYJDR high dosage group, low dosage BSHYJDR group, DDP combined with high and low dosage BSHYJDR group, 10 mice in each group. DDP group received injection intraperitoneally (ip) at the dosage of 1 mg/kg (equal to 1/10 LD50), once a day for 4 d. High and low dosage BSHYJDR groups received intragastric BSHYJDR at the dosages of 26.6 and 13.3 g/kg (20 and 10 times each of clinical adult dosage) respectively, while tumor-bearing model group received the equal volume of distilled water once a day for 10 d. On the 11^th d, the mice were weighed and killed, then the tumor was dissected and weighed, the repression rate (RR) was calculated according to the mean weight of tumor (MWT). RESULTS: Compared to the model group (MWT: 1.30±0.73), DDP group (MWT: 0.41±0.09, RR: 68.46%) had a significant difference in the inhibition of hepatocarcinoma H22 (P〈0.01). High dosage BSHYJDR group (MWT: 0.69±0.29, RR: 46.92%) also had a significant difference in inhibition (P〈0.05), while no difference was found in low dosage BSHYJDR group (MVVT: 0.85±0.34, RR: 34.62%) (P〉0.05). When DDP was combined with high dosage BSHYJDR (MWT: 0.29±0.17, RR: 77.69%) and low dosage BSHYJDR (MWT: 0.38±0.21, RR: 70.77%) respectively, we could see improvement of the inhibition effect of DDP on transplanted hepatocarcinoma H22. DDP combined with high dosage BSHYJDR had a significant difference (P〈0.001) compared to DDP, while DDP combined with low dosage BSHYJDR only had a little improvement that is not remarkable. CONCLUSION: Chinese medicine BSHYJDR in combination with chemotherapy can inhibit transplanted hepatocarcinorna in mice. 展开更多

Clustering analysis is one of the main concerns in data mining.A common approach to the clustering process is to bring together points that are close to each other and separate points that are away from each other.Therefore,measuring the distance between sample points is crucial to the effectiveness of clustering.Filtering features by label information and mea-suring the distance between samples by these features is a common supervised learning method to reconstruct distance metric.However,in many application scenarios,it is very expensive to obtain a large number of labeled samples.In this paper,to solve the clustering problem in the few supervised sample and high data dimensionality scenarios,a novel semi-supervised clustering algorithm is proposed by designing an improved prototype network that attempts to reconstruct the distance metric in the sample space with a small amount of pairwise supervised information,such as Must-Link and Cannot-Link,and then cluster the data in the new metric space.The core idea is to make the similar ones closer and the dissimilar ones further away through embedding mapping.Extensive experiments on both real-world and synthetic datasets show the effectiveness of this algorithm.Average clustering metrics on various datasets improved by 8%compared to the comparison algorithm. 展开更多

Current animal models of nerve root compression due to lumbar disc herniation only assess the mechanical compression of nerve roots and the inflammatory response. Moreover, the pressure applied in these models is static, meaning that the nerve root cannot be dynamically compressed. This is very different from the pathogenesis of lumbar disc herniation. In this study, a chitosan/polyacrylamide double-network hydrogel was prepared by a simple two-step method. The swelling ratio of the double-network hydrogel increased with prolonged time, reaching 140. The compressive strength and compressive modulus of the hydrogel reached 53.6 and 0.34 MPa, respectively. Scanning electron microscopy revealed the hydrogel's crosslinked structure with many interconnecting pores. An MTT assay demonstrated that the number of viable cells in contact with the hydrogel extracts did not significantly change relative to the control surface. Thus, the hydrogel had good biocompatibility. Finally, the double-network hydrogel was used to compress the L4 nerve root of male sand rats to simulate lumbar disc herniation nerve root compression. The hydrogel remained in its original position after compression, and swelled with increasing time. Edema appeared around the nerve root and disappeared 3 weeks after operation. This chitosan/polyacrylamide double-network hydrogel has potential as a new implant material for animal models of lumbar nerve root compression. All animal experiments were approved by the Animal Ethics Committee of Neurosurgical Institute of Beijing, Capital Medical University, China(approval No. 201601006) on July 29, 2016. 展开更多

Objective: To compare internal with external drainage of the pancreatic duct during pancreaticoduodenectomy with regard to the incidence of postoperative pancreatic fistula (POPF) and other complications. Methods: We retrospectively analyzed 316 patients who underwent pancreaticoduodenectomy with a placed drainage tube (external, n=128; internal, n=188) in the pancreatic duct from 1 January 1999 to 31 December 2011 in Tianjin Third Central Hospital of China. The incidence of POPF and some other complications were compared. Results: There was no difference in the incidence rates of POPF between those given an internal or external drainage tube (P=0.788), but POPF was more severe in the former (P=0.014). Intraperitoneal bleeding rate was also higher in the patients with internal drainage (P=0.040), but operative time and postoperative hospitalization were longer in those with external drainage (P=0.002 and P=0.007, respectively). There was no difference between the groups with regard to the incidence rates of gastrointestinal bleeding, delayed gastric emptying, pulmonary infection, or incision infection and in-hospital mortality. Conclusions: External drainage of the pancreatic duct during pancreaticoduodenectomy can decrease the severity of POPF, but operative time and postoperative hospitalization will be extended. 展开更多

BACKGROUND Distal radius fractures accompanied by the volar margin of the lunate fossa(VMLF)lesions are often overlooked or inadequately reduced in clinical practice.AIM To investigate the impact of VMLF fragment in distal radius fractures on the stability and function of the wrist joint.METHODS This was a retrospective study of patients with distal radius fractures who underwent surgical treatment between January 2013 and December 2017.The patients were divided into two groups according to whether the VMLF fragments were fixed or not.X-rays and computed tomography were performed before surgery,immediately postoperatively,and at 1,3,and 6 mo to measure the scapholunate angle,radiolunate angle,capitolunate angle,and effective radiolunate flexion(ERLF).The Mayo wrist score and disabilities of the arm,shoulder,and hand(DASH)score were determined at 1 year.RESULTS Thirty-five patients were included.There were 15 males and 20 females.Their mean age was 52.5±14.3(range:19-70)years.There were 38 wrists(17 on the left side,15 on the right,and three bilateral;16 in the fixed group,and 22 in the unfixed group).The interval between trauma and surgery was from 1 h to 1 mo.The incidence of postoperative wrist instability in the unfixed group(86.4%)was higher than in the fixed group(25.0%)(P≤0.001).Ten patients had ERLF>25°in the unfixed group and none in the fixed group(P=0.019).The Mayo wrist score was 94±5.7 in the fixed group and 68±15.1 in the unfixed group(P<0.001).The DASH score was 4.6±2.5 in the fixed group and 28.5±19.5 in the unfixed group(P<0.001).CONCLUSION Injuries of VMLF,even small fractures,might damage the radial-lunar ligament,leading to postoperative wrist instability,sagittal force line imbalance,and poor recovery of wrist joint function. 展开更多

Objective To assess the prevalence and risk of coronary artery disease(CAD)in Chinese adults with type 2 diabetes mellitus(T2DM)using electron beam computed tomography(EBCT)and EBCT angiography(EBCTA).Methods:Ninety-four cases were enrolled in this study including diabetes(n=28),impaired glucose tolerance(IGT,n=30),coronary heart disease(CHD,n=11),and control(n=25).Cardiac EBCT plain scanning and EBCTA were performed on all of these subjects to evaluate coronary artery calcifica-tion(CAC)scores,and number of segments of stenosed coronary arteries.Both CAC and/or coronary artery stenosis were defined as patients with coronary artery lesions(CAL).Results CAC scores were not different with the control,diabetes,IGT,or CHD(P>0.05)groups.Compared to control(0.520±1.295),more stenosed coronary arteries segments(P<0.05)were detected in diabetes(2.964±1.915),IGT(2.200±2.024),and CHD(2.273±1.679).Number of stenosed artery segments were correlated with age(r=0.215,P=0.019),postprandial glucose(r=0.224,P=0.015),total cholesterol(r=0.323,P=0.000),and duration of diabetes(r=0.208,P=0.004).The incidences of CAL in diabetes(96.43%),IGT(93.33%),and CHD(90.91%)was substantially higher than that in normal control(56.00%,P<0.01).The odds ratio of CAL associated with having diabetes was estimated to be 7.514(95%CI:1.885-63.778).Conclusions Coronary artery lesions are prevalent in Chinese adults with type 2 diabetes,implying a high CAD risk.EBCTA holds potential in depicting the details of CAL and can be used to track the progression of CAD in diabetes patients. 展开更多
