Early diagnosis of inflammation and properly interfere to improve the prognosis are very important.However,it is difficult to verify inflammation or differentiate inflammation from infection in clinic,especially in the condition of underlying inflammation.Currently,radiopharmaceuticals based on researches of pathophysiology progress of diseases are studied constantly.This review summarizes the potential inflammation imaging radiotracers and their mechanisms,potential clinical application value.

Evidence has indicated that low doses of anti-tumor regimens can induce cell apoptosis in vitro, although different regimens induce apoptosis by different mechanism and pathway. In recent years, new tumor treatment strategy has been mainly focused on inducing tumor cell apoptosis. The present review discusses the advantages and disadvantages of inducing tumor cell apoptosis. The benefit of inducing apoptosis is not to cause inflammatory reaction, but as its disadvantage, it inhibits immune responses, and the phagocytosis of apopotic bodies may result in horizontal transfer of genes (including oncogenes and other oncogenic materials), which can be one of the causes of tumor relapse. This paper proposes that the tumor treatment strategy should be turn into promoting tumor cell necrosis and inducing anti-tumor immune responses.

Health management plays an important role in the control of medical costs and in maintaining people' s health.Since the beginning of health management performance in our country,the major problems were:inadequacy of govement's support;imperfect laws;irregular marketing operation;lack of feasible health management model;controversy over long-term economic benefits;lack of awareness on health in common people and so on.To solve these problems,it is necessary to strengthen government support,and enhance people's health awareness,and explore the health management model consistent with the actual situation in China.

Objective To explore the safety and effectiveness of transurethral resection of the prostate (TURP) for large benign prostatic hyperplasia.Methods A total of 56 cases of patients with large benign prostatic hyperplasia were analyzed retrospectively.Results The weight of prostate tissue resected with TURP was 60.2 g (48-122 g).The resection rate was 60％,operation time 113.4 min (70-180 min).The lower urinary tract symptoms (LUTS) after TURP was improved significantly.The international prostate symptom scores (IPSS) of 38 cases were decreased from (25.6±1.5) before operation to (6.0± 2.0) after operation.The maximum urine flow rate were increased from (5.0±1.9) ml/s to (18.0±4.5) ml/s.The mean residual urine volume of 22 cases were reduced from 95 ml (40-250 ml) to 10 ml (0-60 ml).Conclusions Skilled TURP technology for large benign prostatic hyperplasia is a safe treatment with good effect and low complications rates.

OBJECTIVE Xingnaojing injection(XNJ)is an extracts of Angong Niuhuang Pill that is a well-known traditional Chinese medicine used for the treatment of septicemia and stroke.This study aims to investigate the effect of XNJ on intestinal mucosal barrier in septicemia and intracerebral hem-orrhage(ICH)mice models.METHODS The septicemia mice models were induced by intravenous in-jection with lipopolysaccharide(20 mg·kg-1).And the ICH mice models were made by intrastriatal injec-tion of bacterial collagenase. The septicemia animals were treated intravenously with XNJ at dose of 2.5,5,10,or 15 mL·kg-1.The ICH animals were treated intravenously with XNJ at dose of 10 mL·kg-1. Thereafter, the permeability of intestinal mucosa was assayed by FITC-D method. RESULTS Com-pared with the control group(44.72±4.30),the permeability of intestinal mucosa in the mice in septice-mia group (233.68±28.18) was significantly increased (P<0.01). Treatment with XNJ at dose of 5, 10, and 15 mL·kg-1reduced the permeability of intestinal mucosa (150.45 ± 17.52,139.21 ± 17.05,132.55 ± 18.88,respectively, P<0.01)except 2.5mL·kg-1(240.71±21.42,P>0.01);Compared with sham group (57.88±7.31),the permeability of intestinal mucosa in the mice of ICH(282.25±23.78)was significantly in-creased(P<0.01). Treatment with XNJ (10 mL·kg-1)in the mice of ICH group ameliorated the change of permeability in intestinal mucosa (148.83±15.86, P<0.01). CONCLUSION XNJ exhibits the protec-tive effect on the intestinal mucosal barrier in septicemia and ICH, which will prevent the endotoxin to penetrate the intestinal mucosa and then to enter the circulation in infections and stress.

The aim of this study is to construct specific shRNA expressing plasmids, and to observe their effects on H9c2 cardiomyocytes injury induced by hypoxia/reoxygenation (H/R). RIPK1 and RIPK3 are the key kinases mediating the process of necroptosis. Using recombinant DNA technology, we inserted the synthetic shRNA into pSUPER vector to construct RIPK1-shRNA or RIPK3-shRNA plasmid respectively. We transfected H9c2 cardiomyocytes with the two shRNA plasmids respectively, before we treated them with H/R stimulation. Then, we measured the relevant genes and proteins by real-time PCR and Western blot. Meanwhile,we detected the markers of necroptosis and cardiomyocytes injury. The results showed that inhibition of ripk1 or ripk3 gene expression by its specific shRNA might protect the cardiomyocytes injury induced by H/R stimulation.

Objective To investigate the effects of exercising on a cycle ergometer on lower limb motor function and the walking ability of hemiplegic stroke patients.MethodsSixty hemiplegic stroke patients were randomly divided into a treatment group and a control group with 30 in each. Both groups were treated with routine rehabilitation, but the treatment group also undertook cycle ergometer training. The training lasted for 10-20 min/d, 6 d/week for 6 weeks. All patients were assessed with the Fugl-Meyer lower limb assessment ( FMA), functional ambulation category (FAC) classification and the modified Barthel index (MBI) pretreatment and 6 weeks post treatment.ResultsBefore intervention there was no significant difference between the two groups in any of the assessments. Six weeks post treatment, the average FMA, FCA classification and MBI results in the treatment group were significantly better than those pretreatment and better than those in the control group.ConclusionsCycling exercise combined with routine rehabilitation training can distinctly improve the motor function of the lower limbs and the walking ability of hemiplegic stroke patients.

Relapse, which puzzled several generations of hematologists, is the bottle-neck of radical treatment for leukemias. The progress of Human Microbiome Project at the beginning of 21st century suggested that human body was a super-organism constituted by the core of human cells and symbiotic microorganisms. The elucidation and characterization of endogenous retrovirus and prion protein suggested the possible effects of co-evolutional microorganisms on human health. Recently, the elucidation of the roles of tunneling nanotubes in intercellular communication and transportation suggested a novel way for cellular communication and transport of oncogenic materials. The role and significance of in vivo cell fusion have been studied in more detail. On the other hand, donor cell leukemia was reported. All of these approaches provide novel insights for studying the mechanism of leukemia relapse. Based on previous work, the authors suggest the hypothesis: there are two possible mechanisms for the relapse of leukemias: the minimal residual disease (MRD) and intercellular transportation of oncogenic materials.

OBJECTIVETo explore the correlation between hand and face-mouth, so as to provide nerve reflex basis for the theory "Hegu (LI 4) regulates face and mouth".

METHODSSeven hundred and sixty-three participants who met the inclusive criteria were divided into different age groups. The skin around participants' thenar eminence was gently scraped to be observed whether there was an involuntary movement around the face or mouth, which was palmomental reflex. The results of palmomental reflex were recorded.

RESULTSThe total occurrence rate of palmomental reflex was 46.26%. For those who were 0 to 1 years old, the palmomental reflex was all positive; for those who were 21 to 36 years old, the positive rate was 20.45%, which was the lowest; for those who were 65 to 85 years old, more than half of them were positive. The majority of those who were 0 to 2 years old were bilateral positive palmomental reflex, while the majority of those who were 65 to 85 years old were unilateral positive palmomental reflex.

CONCLUSIONThere is a certain connection between hand and face-mouth. The occurrence rate of palmomental reflex changes from high to low over age increasing, and then changes from low to high with the aging, presenting a "high-low-high" U-shaped curve, which is possible related to the growth and recession of nervous system.

The aim of this study was to observe whether necroptosis is involved in the process of cardiac hypertrophy induced by pressure overload. SD rats underwent transverse abdominal aortic constriction (TAC) operation for establishing cardiac hypertrophy model. The structure and function of the left ventricle of rats were evaluated via echocardiography, left ventricular mass index, the expression of markers of cardiac hypertrophy and histological detection. Real-time PCR and Western blot were used to measure the gene and protein expression of receptor interacting protein kinase 1 and 3 (RIPK1 and RIPK3, the necroptosis markers) respectively. Four weeks after TAC operation, rat model for cardiac hypertrophy was established. The experimental data showed that the gene and protein expressions of RIPK1 and RIPK3 in the rat heart hypertrophic tissues after TAC for 4 weeks were increased significantly compared with those in the sham group. HE staining showed cardiomyocytes injury and hypertrophy in the hearts of TAC rat models. By transmission electron microscope, we observed that mitochondria of cardiomyocytes were damaged seriously in the TAC models. Treatment with losartan used, the selective antagonist of angiotensin II type I receptor could improve the cardiac function of TAC rats. Moreover, losartan treatment decreased the expression of RIPK1 and RIPK3 in heart tissues of TAC rats. The results suggest that necroptosis occurrs in the process of cardiac hypertrophy with pressure overload, and losartan could alleviate the cardiac hypertrophy and inhibit necroptosis.
