1.Research progress of relationship between inflammation anti heart failure
Journal of Shanghai Jiaotong University(Medical Science) 2009;29(6):649-653
Accumulating studies have proved that systemic inflammation is one of the important pathophysiologic mechanisms of heart failure. This article focuses on the sources of inflammation mediators and the causes of inflammation activation in heart failure including hemodynamic changes and oxidative stress, Toll-like receptors, microbial antigens and microorganisms, endotoxin hypothesis and neurohormonal activation. Furthermore, the effects of inflammation mediators such as cytokines and chemokines on heart failure are introduced. All lead to the conclusion that heart failure is a process with complex inflammation.

Thirteen novel oleanolic acid (OA) derivatives were designed and synthesized with modification at positions of C-3, C-12 and C-28 of OA. Their structures were confirmed by MS, 1H NMR and elemental analysis. Their in vitro cytotoxicities against various cancer cell lines (SGC7901, MCF-7 and A549) were evaluated by MTT assay. The results indicated that the tested derivatives were found to have stronger cell growth inhibitory activity than OA. Among them, compounds II2 and II3 showed more potent cytotoxicity on MCF-7 and A549 tumor cells than gefitinib (positive control). They are worthy to be studied further.

OBJECTIVETo study the effect of acupuncture on the immune function of sepsis patients.
METHODSNinety sepsis patients were assigned to the control group, the thymosin a1 group, and the acupuncture treatment group according to random digit table, 30 patients in each group. Patients in the control group were treated according to the guideline of Surviving Sepsis Campaign (SSC). Patients in the control group received routine treatment. Those in the thymosin alpha1 group additionally received subdermal injection of thymosin alpha1 (1.6 mg), once per day for 6 successive days. Needling at related points such as Zusanli (ST36), Yanglingquan (GB34), Neiguan (PC6), Guanyuan (RN4), and so on, was performed in patients of the acupuncture treatment group, once per day for 6 successive days. T cell subgroups (CD3+, CD4+, CD8+, CD4+ /CD8+) and immunoglobulin levels (IgG, IgA, IgM) were detected. The length of ICU hospital stay, hospital readmission rate, and 28-day mortality were compared among the three groups.
RESULTSAfter six days of treatment, CD3+, CD4+, CD8+, IgG, IgA, IgM, and CD4+ /CD8+ ratio of three groups were all significantly increased (P < 0.01). Of them, CD3+, CD4+, CD8+, IgG, IgA, and IgM increased more significantly in the thymosin alpha1 group and the acupuncture treatment group (P < 0.01). Compared with the control group, the ICU hospitalization length was significantly shortened, the hospital readmission rate and the 28-day mortality were lower in the thymosin alpha1 group and the acupuncture treatment group (P < 0.05, P < 0.01). There was no statistical difference in each index between the thymosin alpha1 group and the acupuncture treatment group (P > 0.05).
CONCLUSIONAcupuncture could adjust the immune function of sepsis patients, improve their immunological indicators and prognoses.

OBJECTIVETo investigate the relationship between chronic pyelonephritis (CPN) and immune function, and the therapeutic mechanism of Yishenkang granule (YSKG).
METHODSOne hundred and twenty patients of CPN were divided into 3 groups randomly, the YSKG group (treated with YSKG), the control A group (treated with Sanjin tablet) and the control B group (treated with western medicine). Serum levels of immunoglobulin (Ig), complement 3 (C3), interleukin-2 (IL-2), peripheral T-lymphocyte subsets, and urinary secretory immunoglobulin A (sIgA) were determined before and after treatment with monoclonal antibody assay, agar diffusion method, radioimmunoassay (RIA), and radioimmuno-equilibrium method, and compared with normal control.
RESULTSThere were disorders of T-lymphocyte subsets in CPN, lowering of serum Ig, C3 and urinary sIgA, and increase of blood IL-2 (P < 0.05 or P < 0.01). These abnormalities could be normalized after YSKG treatment.
CONCLUSIONFunctional disorders of cellular and humoral immunity exist in CPN patients of chronic stage, YSKG could correct the immune functional disorder, control the recurrence of CPN effectively and alleviate the immunopathological damage.

Objective To report clinical manifestations, electroencephalogram (EEG), and the genotypes of two siblings with type Ⅲ Gaucher disease.Methods Two patients with different features were siblings. Their clinical data, signs, peripheral leukocytes acid β-glucosidase activity, andGBA gene were analyzed.Results (1) The proband was a boy. He visited us at the age of nine years old because of hepatosplenomegaly, thrombocytopenia and growth retardation without any neurologic symp-toms. He had normal intelligence but abnormal EEG ifndings. The activity of acid β-glucosidase in his leucocytes decreased to 1.5 nmol h-1·mg-1 Pr (normal range 6.0-16.7 nmol h-1·mg-1 Pr), supporting the diagnosis of type Ⅲ Gaucher disease. (2) The elder sister of the proband was 12 years old. She had tonic-clonic seizure and myoclonus seizure from the age of seven years old. Mild hepatomegaly, abnormal EEG, poor effect for antiepileptics, and progressive deterioration of psychomotor abilities were found. Her blood leucocytes acid β-glucosidase activity decreased to 1.8 nmol h-1·mg-1 Pr (normal range 6.0-16.7 nmol h-1·mg-1 Pr). Two heterozygous missense mutations, c.680A>G, (p.N188S) and c.1342G>C (p.D409H) were detected from the two siblings, respec-tively.Conclusions Patients with type Ⅲ Gaucher disease usually have the onset in childhood with typical features of Gaucher disease without neurologic involvement. Abnormal EEG may be helpful to the differential diagnosis of type I or type Ⅲ. On the other hand, neurologic manifestations could be presented as the ifrst symptom in some patients without viscera enlargement. The patients of type Ⅲ Gaucher disease with the same genotype could have different phenotypes, even between the siblings.

OBJECTIVETo observe the clinical effect of acupuncture on acute heart failure (AHF) patients.
METHODSTotally 60 patients who were diagnosed as AHF were assigned to the acupuncture group and the control group, 30 in each group. Those in the control group received inotropic agents, preload and afterload reducing therapy, anti-infection and so on. Besides, those in the acupuncture group received needling at relative points, once daily for 5 consecutive days. The mean arterial pressure (MAP), heart rate (HR), cardiac index (CI), stroke volume index (SI), left ventricle working index (LCWI) were monitored by thermodilution pulse-indicated continuous cardiac output (PiCCO) technique. Changes of the aforesaid data were compared between before and after treatment. The ICU length of stay, readmission rate,and the 28-day mortality were also compared between the two groups.
RESULTSAfter 5 days of the treatment, CI, SI, and LCWI increased more obviously (P < 0.01), HR and MAP decreased significantly (P < 0.05). Of them, CI, SI, and LCWI increased more obviously in the acupuncture group (P < 0.05).There was no obvious difference in HR or MAP between the two groups (P > 0.05). Compared with the first day of admission in the same group, CI, SI, and LCWI obviously increased in the acupuncture group from the second day (P < 0.05). HR started to decrease since the fourth day (P < 0.05), and MAP began to decrease until the fifth day (P < 0.05). CI, SI, and LCWI started to increase in the control group from the third day (P < 0.05); HR and MAP both began to decrease since the fifth day (P < 0.05). Compared with the control group, the ICU length of stay was obviously shortened in the acupuncture group (P < 0.05). The readmission rate and the 28-day mortality rate were lower than those of the control group (P < 0.05).
CONCLUSIONThe combination of acupuncture and Western medical therapy might strengthen acute heart failure patients' heart functions, elevate the therapeutic effect, and improve the prognosis.

OBJECTIVETo analyze and summarize the characteristics of glycogen storage disease type II (Pompe disease) patients according to the clinical description and prognosis.
METHODSeventeen Chinese patients diagnosed by acid alpha-glucosidase (GAA) enzyme activity test were reviewed. Clinical data tables were designed. Interviews were made via phone calls. Information was collected to reach the objective.
RESULTFour of 17 patients diagnosed by acid alpha-glucosidase are infantile-onset, symptoms started between 2 to 6 months after birth with increased serum creatine kinase and cardiac problems, with or without respiratory concerns. Other 13 patients were later-onset cases, and their symptoms started between 2 to 22 years of age with increased serum creatine kinase. Eleven later-onset patients started with muscle weakness, 2 patients developed respiratory insufficiency, 2 patients showed scoliosis, and 1 patient expressed increased serum creatine kinase with abnormal liver function. Just 3 of the later-onset patients were treated with mechanical ventilator and adjuvant therapy, others were not. All patients' acid alpha-glucosidase (GAA) enzyme activity analysis showed lower than 10% of normal. Fourteen patients were tested by muscle biopsy pathology, and 9 of them progressed to glycogen storage disease type II; 10 patients received genetic analysis, and 6 of them had two mutations which cause the disorder. Twelve of the 17 patients were interviewed successfully. In 3 of the infant-onset patients the disease resulted in death from respiratory failure, and 1 is still alive at the age of 1 year and 7 months. In 4 of 8 later-onset patients the disease resulted in death from respiratory failure between 3 to 5 years after onset of symptoms. Three of 4 survivors had increased muscle weakness, and 1 patient kept alive with ventilator without any changes. Seven of 12 interviewed patients died, the mortality rate was 58.3%.
CONCLUSIONGlycogen storage disease type II (Pompe disease) present differently in the clinic. Infant-onset Pompe disease is mainly characterized by generalized muscle weakness and obvious cardiac involvement. It's a dangerous disease, with high mortality rate. Later-onset Pompe disease is characterized by chronic proximal muscle weakness and respiratory insufficiency. GAA enzyme activity analysis, muscle biopsy and genetic analysis used to support the diagnosis of Pompe disease. Prognosis of the disease depends on age of onset and respiratory muscle involvement.
