OBJECTIVETo explore protective effects of acupuncture at "Zusanli" (ST 36) on cerebral tissue in rats with sepsis.

METHODSCecal ligation and puncture (CLP) was applied to duplicate the rat model of sepsis. According to random number table, thirty SD rats were divided into a sepsis model group (group A), a sepsis model plus electroacupuncture (EA) group (group B), and a sepsis model plus non-acupoint EA group (group C), ten rats in each one. EA with the same frequency and intensity at "Zusanli" (ST 36) and non-acupoint (0.5 cm laterally to "Zusanli") for 30 min was applied in the group B and group C, respectively. No treatment was given in the goup A. 6 hours after CLP, blood was acquired from abdominal aorta to measure the levels of neuron specific enolase (NSE). Then the rats were sacrificed by abdominal aorta exsanguination to take their cerebral tissue for measuring the levels of tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6).

RESULTSSix hours after CLP, the level of NSE was (3.51 +/- 0.39) ng/mL in group B, which was significantly lower than (7.72 +/- 0.64) ng/mL in group A (P<0.05). The level of NSE was (8.02 +/- 0.72) ng/mL in the group C, which had no statistical significance with group A (P>0.05). The levels of TNF-alpha, IL-6 in cerebral tissue in group B were significantly lower than that of group A and C (all P>0.05).

CONCLUSIONEA at "Zusanli" (ST 36) has certain protective effect on septic rat's brain, which has some relationship with decreasing levels of cerebral tissue proinflammatory cytokine and plasma NSE. EA at non-acupoint has no the same action.

Objective To investigate the variations of the expression and activity of phosphatidyl inositol-3 kinase(PI-3K)in the adipose tissue of pregnant women with gestational diabetes mellitus(GDM)and to explore its relationship with insulin resistance(IR)in these women.Methods The expression of PI-3K p85aprotein and mRNA in adipose tissue were detected by Western blot and Semi quantitative reverse transcription polymerase chain reaction(RT-PCR)in 20 GDM women(GDM group)and 20 normal pregnant women(normal group).The activity of PI-3K was determined by ELISA and IR index was calculated using homeostasis model assessment(HOMA)according to the results of fasting insulin(FINS)and fasting plasma glucose(FPG),which measured by oxidase assay and immunoradioassay,respectively.Results The expressions of PI-3K p85αmRNA and PI-3K p85a protein were markedly increased in the adipose tissue of GDM group than in the normal group(mRNA:0.83±0.03 vs 0.53±0.07,P＜0.01;protein:0.93±0.04 vs 0.71±0.06,P＜0.01).However,the PI-3K activity in the GDM groups was significantly down-regulated compared with the normal group(1.7±0.6 vs 5.2±0.5,P＜0.01).The levels of FPG and FINS (HOMA-IR)in the GDM group were all significantly higher than the normal group[FPG:(5.8±0.2)mmol/L vs(4.7±0.3)mmol/L;FINS:(14.8±0.2)mmol/L vs(11.2±0.3)mmol/L;HOMA-IR:1.3±0.4 vs 0.9±0.3,a11 P＜0.01]. Conclusions The decreased activity of PI-3K in the adipose tissue may be one of the molecular mechanisms for IR in GDM.

Objective To investigate the expression and tyrosine phosphorylation of insulin receptor substrate-1 (IRS-1) and in the adipose tissue of patients with gestational diabetes mellitus (GDM), and to explore molecular mechanisms of insulin resistance in GDM. Methods The serum and adipose tissue were sampled from patients with GDM (GDM group, n = 20) and normal pregnant women (control group, n = 20). Fasting plasma glucose was measured by glucose oxidase assay. The expressions of IRS-1 protein and mRNA were determined by Western blot and semi-quantitative RT-PCR. The tyrosine phosphorylation of IRS-1 was measured by immunoprecipitation. Results Compared with control group, in GDM group, the expression of IRS-1 mRNA was markedly decreased (0.61 ±0.06 vs 1.12 ± 0.17, P < 0.01), the expression of IRS-1 protein was significantly decreased (0.57 ±0.08 vs O. 83 ±0.07, P <0.01) and tyrosine phosphorylation was significantly reduced (0.23 ± O. 06 vs O. 62 ±0.04, P < 0.01) in the adipose tissue. Conclusion The decline of protein expression and tyrosine phosphorylation of IRS-1 in the adipose tissue of gestational diabetes appears to be one of the moleculemechanisms of insulin resistance in patients with GDM.

This study analyze the characteristics and clinical medicine in 17 hospitals all over China, based on hospital information system diagnostic information database, including 4 497 cases of hospitalized patients with Parkinson's syndrome. Results indicate, the most common comorbidities are infarction, hypertension, coronary heart disease, diabetes and lung infections, including cerebral infarction, the combined incidence of hypertension in men reached 33.46% and 30.05%, respectively, it is slightly lower in the females. Men with coronary heart disease are more than women, women with diabetes and bone disease are more than men. Combined incidence of the disease increases with age, vascular factors occupy an important position. The most common combined diseases in patients with 90 years of age or older are coronary heart disease, lung infection, and often accompanied by metabolic disorders and nutritional emergency, critical care. Constipation, depression, anxiety, sleep disorders, cognitive impairment are common non-motor symptoms. The drug categories associated with Parkinson's core symptoms treatment are about 20% to 30% of clinical medicine, the others are associated with the treatment of combined disease, clinical medicine and disease spectrum consistent. Blood circulation topped Chinese agents applied frequency, reaching 44.52%; laxative drugs accounted for 11.66%; detoxification agent representing 9.46%. The first twenty Chinese medicine of the applying frequency reached 56.07% of the total utilization, including 12 kinds of traditional Chinese medicine injections, accounting for 60%. Therefore, in the diagnosis and treatment of Parkinsons syndrome, the treatment of comorbidities is very important, more attentions should be paid to vascular factors of the disease, Chinese medicine should be more concerned to improve the non-motor symptoms, give full play to the pharmaceutical multi-target, the overall regulation of advantages, integrative medicine, and improve the quality of life of patients.

Aim To investigate the effect of asiatic acid on apoptosis and autophagy in human glioblastoma T98G cells. Methods MTT colorimetry was employed to assay the cellular proliferating activity. The fluores-cence microscope and Hoechst 33258 staining were used to detect the morphological changes. The cell ap-optosis and autophagy were analyzed by flow cytometry with Annexin-V/7-AAD and MDC staining respective-ly. The expressions of associated proteins were detected by Western blot to analyze the mechanism of apoptosis and autophagy. Results MTT assay showed that the growth of T 9 8 G cells was inhibited by asiatic acid ( IC50 =46. 3 μmol · L-1 ) . Annexin V/7-AAD stai-ning and Western blot revealed that asiatic acid in-duced apoptosis in T98 G cells by reducing the expres-sion of Akt, decreasing the mitochondrial membrane potential, and increasing the expression of Caspase-3. MDC staining and Western blot showed that the per-centage of MDC-positive cells was decreased and the expressions of Beclin-1 , LC3-II and Atgs were inhibi-ted by asiatic acid treatment. 5 μmol·L-1 chloroquine was used to up-regulate the expressions of LC3-Ⅱand Beclin-1 . Asiatic acid-inhibited autophagy was blocked and the total apoptotic rate was reduced remarkably. Conclusion Asiatic acid suppresses T98 G cells pro-liferation by inducing apoptosis and inhibiting cell au-tophagy, and the very role of inhibiting autophagy could promote apoptosis to a certain extent.

Objective To investigate the forensic characteristics of death cases of Acute Interstitial Pneumonia (AIP), so as to provide references for forensic assessment of AIP. Methods The data of 27 AIP death cases were retrospectively analyzed. The data included the population characteristics, toxicology, pathology and causes of death. Results All 27 patients had clinical symptoms including fever, cough and chest tightness, 25 patiens of them were treated as upper respiratory tract infection in local hospital, and finally died of deteriorating condition. The forensic diagnosis after autopsy showed the 27 cases were died of respiratory failure caused by AIP. Conclusion AIP is a disease with rapid progression and often leads to medical disputes,the patient's families often have different opinion on the death cause of patients with the hospital,so forensic identification of the cause of death is conducive to resolve the disputes.

In-vitro assay methods were established to evaluate transactivation and binding activity of compounds on peroxisome proliferator-activated receptor y (PPARγ). Firstly, plasmids were constructed for transactivation assay of PPARγ response element (PPRE) triggered reporter gene expression, and for cell-based binding activity assay of the chimeric receptor, which was fused with PPARγ ligand binding domain (LBD) and yeast transcriptional activator Gal4. Secondly, by using PPARy competitive binding assay based on time resolved-fluorescence resonance energy transfer (TR-FRET), affinities of compounds and drugs to PPARγ were evaluated. In application of these above methods, the PPARγ activating potency and characteristics of different compounds were evaluated, and a novel benzeneselfonamide derivative, ZLJ01, was found to have comparable binding activity and affinity with the well-known PPARy agonist, but lack of PPRE mediated transactivation activity. In preliminary study on in-vitro hypoglycemic activity, ZLJ1 was found to promote insulin-stimulated glucose uptake by liver cells. Therefore, we believe that combining transactivation and binding activity as well as affinity evaluation, the system could be used to screen non-agonist PPARγ ligand as anovel PPARγ modulator
