Severe acute pancreatitis is the systemic inflammatory reaction caused by the preternatural activation of trypsogen. The necrotizing pancrea as the antigen or stimulant, activiates immunocyte and in-flammatory cell to release a great deal of cytokines, including proinflammatery factor and anti-inflammatory factor. The former aggravates the damage of constitution, the latter could antigonize the damage of anti-inflam-matory factor. The unbalance of pro-and anti-inflammatory cytokines ,leads to the occurrence of systemic in-flammatory syndrome, even the mutiple organ failure.

ObjectiveTo evaluate the treatment efifcacy of the treatment promotion of standardized management for chil-dren with asthma.MethodsMedical records of 150 children with asthma were reviewed and divided into management group or control group according to whether standardized management was accepted. Comprehensive asthma education for asthma pa-tients and their parents including asthma associated basic knowledge education, health education as well as follow-ups at deifned intervals was conducted in 78 cases. In the meantime, standardized asthma therapies were performed. Control group involved 72 cases who did not receive asthma education managements and only accepted regular clinical therapies. After 1-year observational follow-up, , clinical efifcacy of children with asthma, changes of knowledge-attitude-practice of parents, and compliance of med-ication were compared between the two groups.ResultsAfter promotion of standardized managements treatment, asthma con-trol rates in the management group were signiifcantly higher than that of the control group(χ2=54.68,P<0.01); In addition, the rate of asthma attacks, emergency visits as well as hospitalizations were obviously reduced in the management group than control group (both withP<0.01). Knowledge associated with asthma, therapy and management executions as well as knowledge-atti-tude-practice of parents also demonstrated apparent elevations in the management group (P<0.01); At the same time, management group has illustrated superior medication compliance over the control group (χ2=66.27,P<0.01).ConclusionPromotion of standardized treatment management among children with asthma can help to achieve effective control by raising levels of knowl-edge-attitude-practice of the parents as well as the patient’s compliance to the treatment.

Objective:To explore influence of nasal continuous positive airway pressure (nCPAP)on maximal oxygen uptake (V · O2 max )etc.in patients with chronic congestive heart failure (CHF)complicated moderate-to-severe ob-structive sleep apnea-hypopnea syndrome (OSAHS)and explore its significance.Methods:A total of 83 CHF com-plicated moderate-to-severe OSAHS patients were selected and randomly divided into routine treatment group (n=40)and nCPAP group (n = 43).Both groups were treated for six months.Left ventricular ejection fraction (LVEF),apnea hyponea index (AHI)and V · O2 max were measured and compared between two groups before and af-ter treatment.Results:Compared with routine treatment group after six-month treatment,there was significant re-duction in AHI [(27.5±6.2)vs.(6.8±1.2)],and significant rise in LVEF [(0.45±0.07)vs.(0.48±0.05)]and · V O2 max [(16.5±3.5)ml·kg-1 ·min-1 vs.(19.2±3.4)ml·kg-1 ·min-1 ]in nCPAP group,P <0.05 all.Con-· clusion:The nCPAP can improve ventilation function,heart function and V O2 max in patients with CHF complicated moderate-to-severe OSAHS,who have received basic medication.

Objective Few studies are reported on the construction of a finite element model of human complex knee joint using multimodality CT and MRI images.In this study, we developed a finite element model of the knee joint for total knee arthroplasty (TKA) using matched and fused CT and MRI data, hoping to provide a useful tool for the simulation study of knee joint biomechanics of TKA.Methods The CT and MRI image data about an intact knee of a 26-year-old male volunteer were imported into the Mimics software for the establishment of 3D models of bony and soft-tissue structures.A complete knee model was developed following the registration and fusion of the constructed 3D models based on the external landmarks.After the simulated implantation of TKA components, a finite element model of the TKA knee was constructed with the Hypermesh software.Then the finite element model was analyzed following the definition of its material behavior, boundary conditions and loading.Results The finite element model of the TKA knee, which was composed of bones, ligaments, components, polyethylene insert and bone cement, was developed from CT-MRI image registration and fusion and maintained its important spatial relationship among different structures in the TKA knee.The results obtained from the finite element analysis showed the characteristics of stress distribution in the TKA knee.Conclusion The finite element model of the knee joint for TKA can be established by matching and fusing CT and MRI image data, which can be employed as a useful tool for the study of knee joint biomechanics of TKA.

Objective To study the importance of back pain-lassitude as the key symptom in the differentiation of kidney-deficiency syndrome in diabetes patients.Methods Totally 460 diabetics were divided into the pain group(154 cases)and non-pain group(306 cases).The 39 symptoms,signs and behavior were abstracted and each patient was scored according to the details of kidney deficiency scale to analyze the constitution and distribution of kidney-deficiency syndrome.Results There was a significant difference in the total symptom score of the two groups(P

Objective To evaluate the security of catheter-based renal denervation by two dimensional speckle tracking imaging.Methods 20 dogs was ablated,whose indicies of heart and blood pressure were detected 6 weeks later.Standard 2D images were acquired in the 2-,3-and 4-apical views as well as the parasternal short-axis views at the level of the mitral valve and papillary muscles.The time to peak-systolic strain of each segment in the level of the mitral valve and papillary muscles,the standard deviation of the time to peak-systolic strain,the peak strain of the longitudinal 12-segment were recorded.Parameters were compared among the before and after ablation.Results Compared with before ablation of renal sympathetic nerve,the systolic pressure and diastolic pressure didn't reduced significantly after the ablation of renal sympathetic nerve (P ＞ 0.05),while there were no significant difference in the peak strain of the longitudinal 12-segment,the dyssychrony parameters and the size of the heart cavity before and after ablation(P ＞0.05).Conclusions The pressure had no change after the ablation of renal sympathetic nerve while without harmful effect on the the size of the heart cavity,the function of the myocardial contraction and the dyssychrony parameters.The ablation of renal sympathetic nerve can' t lower the normal blood pressure and be safe for heart at the same time.

Objective To evaluate the synchrony of heart after catheter-based renal denervation by two dimensional speckle tracking imaging.Methods Each renal sympathetic nerve of 20 dogs were ablated,and the index of heart and blood pressure were detected 6 weeks later.Standard 2D images were acquired in the 2-,3-and 4-apical views.The times from QRS onset to peak-systolic strain rate and to peak-diastolic strain rate were measured for the longitudinal 16-segments in Qlab software,and the standard deviation were calculated.The time to peak longitudinal strain rate and time to peak contraction strain rate of left atrium were measured for each segment contained septal,latera,anterior and posterior in the level of the basal segments,middle sections and apical in Qlab software,and the standard deviation were calculated.Parameters were compared among the before and after of the ablation.Results The systolic pressure and diastolic pressure had no changes after the ablation of renal sympathetic nerve (P ＞ 0.05).The R-R showed a increasing trend,but no significant differences(P ＞0.05).The peak time of LV systolic and diastolic strain rate had a extended trendency too,but no differences(P ＞0.05),and standard deviations of the peak times had no significant differences(P ＞0.05).The peak time of LA longitudinal strain rate and contraction strain rate had a extended trendency,but no obvious change (P ＞0.05),and the standard deviations of the peak times had no significant differences (P ＞0.05).The size of the heart cavity had no differences(P ＞0.05).Conclusions The systolic pressure and diastolic pressure have no changes after the ablation of renal sympathetic nerve,and the synchrony parameters of LV and LA have no significant differences,demonstrate that the synchrony of heart is not affected by the renal sympathetic denervation.

The cDNA fragment of JEV prME gene was cloned into the baculovirus shuttle vector (bacmid) to construct a recombinant baculovirus vector, defined as AcBac-prME. Then the recombinant baculovirus Ac-prME was obtained by transfecting Sf9 cells with AcBac-prME. Western blot analysis and immunofluorescence results indicated that both prM and E proteins were efficiently expressed in Sf9 cells. Electron microscopy suggested that prME was assembled into JEV-VLPs. To further evaluate the potential of JEV-VLPs as vaccine, the mice were immunized with JEV-VLPs and then challenged with lethal JEV. The results of mice survival and pathological changes demonstrated that the JEV-VLPs performed complete protection against JEV-P3 strain and relieved pathological changes in the mice brain significant. This study suggest that JEV-VLPs would be a potential vaccine for Japanese encephalitis virus.

Traditional Chinese medicines have demonstrated clinical efficacy in preventing and treating chemotherapy-induced peripheral neuropathic pain(CIPNP).However,their specific clinical application and mechanism of action require further in-depth study and exploration.There is thus a need to develop more accurate and clinically relevant animal models that reflect the occurrence and development of human diseases as a tool for research.This review provides an in-depth analysis and discussion of the recent establishment and detection criteria of existing rat and mouse animal models of paclitaxel-induced peripheral neuropathic pain.We also evaluate and explain the application of these models for the prevention and treatment of CIPNP in traditional Chinese medicine,thus providing a theoretical basis and reference for future experimental and mechanistic research on the subject.This research will benefit clinical practice and promotion,offering valuable insights into preventing and treating CIPNP using traditional Chinese medicines.

Most of the CHD patients reveal string pulse, mainly due to damage of heart function, lowering of arterial compliance and increase of total peripheral resistance. The common pulse in patients of blood diseases reveal frequent, tiny, string and slippery characteristic, mostly due to the increase of compensatory pumping action of the heart, shortening of ejection time of the left heart, with better vessel compliance and hemorheology, low total peripheral resistance.
