OBJECTIVETo explore the expression of Ghrelin and high mobility group protein B1 (HMGB1) in the serum and the intestinal tissue of sepsis model rats, and to evaluate the effect of electro-acupuncture (EA) at Zusanli (ST36) on the expression of HMGB1 and Ghrelin.

METHODSForty-eight male Wistar rats were randomly divided into four groups, i.e., the sham-operation (sham), the cecal ligation and puncture group (CLP), the CLP + EA at Zusanli (ST36) group (EA), and the CLP + Ghrelin receptor blocking agent + EA group (GHSRA), 12 in each group. A sepsis rat model was prepared by CLP. The incision of the abdominal wall was immediately sutured along the ventral midline for rats in the Sham group. In the EA group EA at Zusanli (ST36) was performed 20 min after CLP surgery with the constant voltage (2 - 100 Hz, 2 mA) for 30 min. In the GHSRA group, Ghrelin receptor blocking agent, [D-Arg1, D-Phe5, D-Trp79, Leu11]-substance P (700 nmol/kg), was administered through intravenous injection immediately after CLP, and 20 min later, EA at Zusanli (ST36) was performed in the same way as for rats in the EA group. Blood samples were withdrawn 12 h after CLP. The serum levels of Ghrelin and HMGB1 were detected using ELISA. Ghrelin expressions and the number of Ghrelin immunopositive cell in the jejunum were determined by immunohistochemistry. HMGB1 contents of the jejunum tissue were detected by Western blotting.

RESULTSCompared with the Sham group, the number of serum immunopositive cells and the expression of HMGB1 in the jejunum tissue significantly increased and levels of Ghrelin and the expression rate of immunopositive cells significantly decreased in the CLP group (P < 0.05). Compared with the CLP group, the number of serum immunopositive cells and the expression of HMGB1 in the jejunum tissue significantly decreased, but levels of Ghrelin and the expression rate of immunopositive cells significantly increased in the EA group (P < 0.05). Compared with the EA group, the number of serum immunopositive cells and the expression of HMGB1 in the jejunum tissue significantly increased in the GHSRA group (P < 0.05), but there was no statistical difference in levels of Ghrelin between the two groups (P > 0.05). The serum level of HMGB1 was negatively correlated with Ghrelin in the Sham group, the CLP group, and the EA group (r = -0. 528, P < 0.01).

CONCLUSIONSEA at Zusanli (ST36) could inhibit the expression of HMGB1 in the jejunum of septic rats, and promote the expression of Ghrelin. The expression of HMGB1 was inhibited by Ghrelin receptor blocking agent, which suggested that the anti-inflammation of EA at Zusanli (ST36) might be associated with Ghrelin.

Objective To seauch the ideal management for gross hematuria in autosomal dominant polycystic kidney disease (ADPKD).Methods ADPKD patients who were ever hospitalized and followed up in our department since 1993 were enrolled in the study.Demographic and clinical data were colloected,such as gender,age of gross hematuria,level of renal function,causative factors,management strategies,duration of gross hematuria,blood platelet count,activated partial thromboplastin time,prothrombin time,international normalized ratio,size of kidney cyst and so on.ADPKD patients were divided into different groups according to causative factors or management.The clinical data were compared among groups.Results A total of 905 ADPKD patients were screened,among whom 279 patients ever had gross hematuria (male/female:150/129),One hundred and forty-six patients had integrated therapeutic process records,while only 101patients could provide relevant laboratory examination results.In these 101 patients,gross hematuria was found in any stage of chronic kidney disease (CKD); the average eGFR was (56.4±44.1) mml·min-1 ·(1.73 m2)-1; the duration of gross hematuria was (8.8±8.0) d; no significant difference between male and female in duration of gross hematuria existed [(8.2±7.3) d vs (9.5±8.8) d,P=0.426]; coagulation parameters were all normal.The platelet count was also normal in 91 patients.Duration of gross hematuria among groups divided according to different causative factors was significantly different (P＜0.05).The patients in bed rest group had significantly shorter duration of gross hematuria compared with other groups (P＜0.05).The platelet count,prothromhin time and international normalized ratio were all at similar level in different groups.Conclusions The causative factors in ADPKD patients with gross hematuria should be confirmed as the first step of management strategies.Bed rest is the key point in management.Antifibrinolytic agent is a proper choice in the cases receiving bemostatic drugs.It is unnecessary to use antibiotic agent for prevention.

More than one hundred strains of marine molds have been isolated from the sediment and the sample of seawater collected from the South China Sea. By the first screening, more than 30 strains of marine molds which can inhibit tested fungi such as Candida albicans and Fursarium sp. were obtained.The results of the second screening showed those strains designed as B 4#-6、B 4#-3、1-B 6-6、1-B 6-10-5、1-B 6-22、C 2#-5、A 2-9 and 1-B 6-10 can produced extracelluar antifungi metabolic products and the crude extract of the strains 1-B 6-10-5 and B 4#-3 can inhibit the growth of many other species of fungi.

Objective：To study the clinical and pathologic features of patients with lupus nephritis (LN) whose myeloperoxidase anti-neutrophil cytoplasmic antibody (MPO-ANCA) were positive. Methods：The clinical and pathological features were analyzed in 18 patients with LN whose MPO-ANCA were positive. And the data of patients with different clinical outcomes were compared. Results：（1）The hematological abnormalities, hypertension and serositis in these patients were more common than general ones with LN. （2）Proteinuria and hematuria were common, the morbidities of gross hematuria and renal failure in these patients were higher than general ones with LN.（3）Various autoantibodies were positive in these patients.（4）Segmental necrosis crescentic nephritis accompanied by density of immunocomplex in glomeruli and vasculitis in intestitium were common.（5）The morbidity of ESRF and mortality of these patients were similar to general ones with LN. The morbidity of tubular atrophy in those with poor prognosis was significantly higher than those survived. Conclusion：The patients with LN whose MPO-ANCA are positive have some difference from those with negative MPO-ANCA, but positive MPO-ANCA is not directly related to the prognosis.

OBJECTIVE To investigate the anti- tremor effect and mechanism of baicalein on oxotremorine- induced muscle tremor in mice. METHODS The acute model of muscular tremor was induced by intraperitoneal injection of oxotremorine, and the latency, duration and frequency of muscle tremor in mice were measured immediately; the saliva of mice was measured to reflect the correlation between tremor and peripheral nerve function; the aim of this study was to determine the content of MDA and the activity of GSH-PX, and to investigate the anti-oxidation of mice with tremor model. The activity of acetylcholinesterase (AchE) and acetylcholine transferase (ChAT) can indirectly reflect the level of acetylcholine in the brain. The level of monoamine neurotransmitters in brain tissue was determined by high performance liquid chromatography (HPLC-ECD). RESULTS The animals in the model group appeared obvious tremoring, salivating and erecting and other symptoms. Compared to the model group, there was no obvious inhibitory effect on the administration of each dose. After 7, 14, 21 and 28 d of continuous administration, the latency, duration and tremor frequency of tremor mice were significantly shortened, the levels of acetylcholine were significantly decreased, the changes of DOPAC and DA neurotransmitters in the brain of model group were recovered, regulate the dynamic balance of acetylcholine and dopamine in the brain. CONCLUSION Long- term administration can improve the tremor behavior of mice, the mechanismmay be related to the regulation of neurotransmittersin brain.
