Objective To analyze the clinical characteristic of Chinese autoimmune pancreatitis (AIP) patients.Methods All clinical data of 81 patients with a diagnosis of AIP in Shanghai Changhai Hospital from February 2005 to May 2012 were analyzed.Results The sex ratio was 7.1∶1 and the mean age was (57± 12) years old in 81 patients with AIP.Obstructive jaundice was the initial symptom in 51.9％ (42/81) patients.In patient receiving CT,focal and diffuse type accounted for 45 and 35 patients.respectively,and pseudocyst was the main manifestation in 1 patient,biliary tract was involved in 59(72.8％ ) patients,dilatation of main pancreatic duct was observed in 5 ( 11.1％ ) patients.In patients receiving PET-CT,diffuse increased Flourine-18 FDG uptake by the pancreas was found in 11 patients,focal increased uptake in 2patients,and significant extra-pancreatic uptake was found in 5 patients.The positive rate of serum IgG4,CA19-9,ss DNA,anti-nuclear antibody and ds-DNA antibody was 94.6％ (53/81),54.4％ (37/68),14.3％ (4/28),10.7％ (3/28),7.1％ (2/28),respectively.The pathological findings of H-E staining and IgG4 immunohistochemical analysis in 20 patients were consistent with lymphoplasmacytic sclerosing pancreatitis.Conclusions Type 1 AIP is the main subtype of AIP in China.Combining clinical symptoms,extra-pancreatic manifestations,imaging or nuclear medicine findings,serology,cytology or histology can effectively increase the correct diagnosis rate of AIP.

Objective:To observe the lipid-lowering effect of different transdermal absorption enhancers applied to the herbal cake-partitioned moxibustion in hyperlipidemia model rabbits, and to explore the possible mechanism. Methods:Forty New-Zealand rabbits were randomly divided into 5 groups using the random number table method, with 8 rats in each group. Rabbits in the blank group were fed routinely with normal diet; rabbits in the other groups were fed with high-fat diet for 12 weeks to establish the hyperlipidemia model. Rabbits in the blank and the model groups were not treated. After the model was prepared, rabbits in the non-transdermal absorption enhancer group received herbal cake-partitioned moxibustion without transdermal absorption enhancer; rabbits in the laurocapram group and the borneol group received herbal cake-partitioned moxibustion with laurocapram or borneol respectively. After 4 weeks of treatment, serum was collected for enzyme-linked immunosorbent assay (ELISA), and the liver tissues were isolated for immunohistochemistry, quantitative polymerase chain reaction (qPCR) and Western-blotting (WB) detection. Results: Serum ELISA results showed that leptin was significantly decreased in the model group compared with the blank group (P＜0.05); compared with the model group, leptin was significantly increased in the non-transdermal absorption enhancer, the laurocapram and the borneol groups (all P＜0.05); compared with the non-transdermal absorption enhancer group, leptin was significantly increased in the laurocapram group and the borneol group (both P＜0.05); there was no significant difference in leptin between the laurocapram and the borneol groups (P＞0.05). The qPCR results of rabbit liver tissues showed that the mRNA expressions of leptin, Janus kinase 2 (JAK2) and signal transducer and activator of transcription 3 (STAT3) in the model group were significantly lower than those in the blank group (all P＜0.05); compared with the model group, the mRNA expressions of leptin, leptin receptor (LR), JAK2 and STAT3 in the non-transdermal absorption enhancer, the laurocapram and the borneol groups were significantly increased (all P＜0.05); compared with the non-transdermal absorption enhancer group, the mRNA expressions of leptin, LR, JAK2 and STAT3 in the laurocapram and the borneol groups were significantly increased (all P＜0.05); compared with the laurocapram group, the mRNA expressions of leptin, LR, JAK2 and STAT3 in the borneol group were significantly increased (P＜0.05). The trend of immunohistochemistry and WB detection results was basically consistent with the qPCR assay results. The immunohistochemistry and WB detection results of phosphorylated JAK2 (phospho-JAK2) and phosphorylated STAT3 (phospho-STAT3) were basically consistent with those of JAK2 and STAT3. Conclusion: The molecular expression of Leptin/JAK2/STAT3 pathway in the hyperlipidemia model rabbits was decreased. The molecular expression of Leptin/JAK2/STAT3 pathway was significantly increased after the herbal cake-partitioned moxibustion. The application of laurocapram and borneol, as transdermal absorption enhancers, in the herbal cake-partitioned moxibustion could more obviously up-regulate the factors of the Leptin/JAK2/STAT3 lipid-regulating pathway than the herbal cake-partitioned moxibustion alone.

OBJECTIVETo study the clinical effects of menisci reformation and repair for the treatment of discoid meniscus injuries and to explore the operation methods.

METHODSFrom Jun. 2005 to Dem. 2009, 28 patients underwent arthroscopic menisci reformation and repair for discoid meniscus, including 23 males and 5 females, ranging in age from 6 to 42 years, with an average of 32 years. The nature of meniscus and the type and range of tear were judged under arthroscope. The menisci reformation and repair were used to treat discoid meniscus tear at the edge. After the operation, the brace was used for 8 weeks, and heavy exercise should be avoided for 6 months. The Lysholm score was adopted to evaluate therapeutic effects.

RESULTSAll the patients were followed up ranging from 3 to 36 months, averaged 8 months. The preoperative Lysholm scores ranged from 62 to 74, with a mean of (67.23 +/- 5.24), and the postoperative Lysholm scores ranged from 80 to 96, with a mean of (87.24 +/- 5.26). There was no occurrence of re-tear or re-operation due to symptom recurrence.

CONCLUSIONThe menisci reformation and repair has better clinical effects on the treatment of discoid meniscus tear and can be regarded as one of the operational options.

Objective: To observe the effects of laurocapram and borneol as transdermal penetration enhancers applied to herbal cake-partitioned moxibustion on liver lipids, hormone-sensitive lipase (HSL) and hydroxymethylglutaryl CoA (HMG-CoA) reductase in hyperlipidemia rabbits.Methods: Forty New-Zealand rabbits were randomly divided into 5 groups using the random number table method, with 8 rats in each group. Rabbits in the blank group were fed routinely with a normal diet; rabbits in the other groups were fed with high-fat diet for 12 weeks to establish the hyperlipidemia model. Rabbits in the blank and the model groups were not given any intervention. After the model was prepared successfully, rabbits in the non-transdermal penetration enhancer group received herbal cake-partitioned moxibustion without transdermal penetration enhancers; rabbits in the laurocapram group and the borneol group received herbal cake-partitioned moxibustion with laurocapram or borneol respectively. After 4 weeks of treatment, the serum was isolated and enzyme-linked immunosorbent assay (ELISA) was applied for the detection of HSL and HMG-CoA reductase. The liver tissues were isolated, and total cholesterol (TC) and triglycerides (TG) were measured by enzymatic methods. One-step method was applied for high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) detection, and transmission turbidimetry was for apolipoprotein A1 (Apo-A1) and apolipoprotein B (Apo-B) detection. Results: The serum concentrations of the drugs in the laurocapram and the borneol groups were significantly higher than those in the non-transdermal penetration enhancer group (both P<0.05); all drug penetrations in the borneol group were significantly higher than those in the laurocapram group (both P<0.05), except for tanshinone ⅡA. Compared with the non-transdermal penetration enhancer group, the HSL was significantly increased while the HMG-CoA reductase was significantly decreased in the laurocapram and the borneol groups (both P<0.05); between groups, the HSL in the borneol group was significantly higher than that in the laurocapram group (P<0.05). Compared with the blank group, the levels of LDL-C, TG, TC and Apo-B in rabbit liver were significantly increased in the model group (P<0.05); compared with the model group, the levels of LDL-C, TG, TC and Apo-B in the non-transdermal penetration enhancer, the laurocapram, and the borneol groups were significantly decreased (all P<0.05); between groups, the TG and TC in the laurocapram group and the LDL-C, TG, TC and Apo-B in the borneol group were significantly lower than those in the non-transdermal penetration enhancer group (all P<0.05), and the TG, LDL-C and Apo-B in the borneol group were significantly lower than those in the laurocapram group (all P<0.05). Compared with the blank group, the HDL-C and Apo-A1 were significantly decreased in the model group (both P<0.05), while compared with the model group, the HDL-C and Apo-A1 were significantly increased in the non-transdermal penetration enhancer, the laurocapram, and the borneol groups (all P<0.05). Between groups, the Apo-A1 in the laurocapram group, the HDL-C and Apo-A1 in the borneol group were significantly higher than those in the non-transdermal penetration enhancer group (all P<0.05).Conclusion: The application of laurocapram and borneol, as transdermal penetration enhancers, in herbal cake-partitioned moxibustion can promote the penetration of the drugs in the herbal cake, increase the levels of HDL-C and Apo-A1, improve the metabolism of HSL and HMG-CoA reductase, and also simultaneously reduce the levels of TC, TG, LDL-C and Apo-B in the liver. The transdermal penetration enhancement effect of borneol is slightly better than or equivalent to that of laurocapram.

Neonatal chylothorax is a common cause of neonatal congenital pleural effusion and is often caused by the accumulation of chylous fluid in the thoracic cavity due to the rupture of the thoracic duct and its branched lymphatic vessels for a variety of reasons. Neonatal chylothorax caused by malignant tumors is extremely rare, and this is the first case of neonatal mediastinal neuroblastoma with chylothorax in China. The boy was found to have pleural effusion in the left thoracic cavity in the uterus, and experienced apnea at birth, as well as dyspnea and cyanosis as the main manifestations after birth. He was diagnosed with left chylothorax based on conventional biochemical analysis of pleural effusion. After the treatment including persistent chest drainage and symptomatic and supportive treatment, the drainage of the left thoracic cavity reached a volume of 90-180 mL per day. Neonatal refractory chylothorax was considered. Chest radiograph on day 13 after birth showed lesions in the upper left lung field, and contrast-enhanced plain CT scan of the chest suggested the possibility of posterior mediastinal neuroblastoma. The autopsy confirmed giant posterior mediastinal neuroblastoma (poorly differentiated), which involved the C7-T6 spinal canal and the nearby erector spinae, with a small amount of tumor tissue in the liver and both adrenal glands. Mediastinal tumor is considered the underlying cause of chylothorax in this case.

OBJECTIVEThe minor allele T of rs113420705 (C/T) in caspase-3 gene (CASP3) has been found to significantly increase the risk of Kawasaki disease (KD) and complicate coronary artery lesions (CALs) in Japanese children. In this study, we have explored association of single nucleotide polymorphisms (SNPs) of CASP3 gene and clinic phenotypes of KD.

METHODSA total of 238 unrelated KD patients and 364 healthy controls with matched age, gender and ethnic origins were recruited. Genotypes of the 3 SNPs were determined with PCR-restriction fragment length polymorphism (PCR-RFLP) and DNA sequencing. Allelic, genotypic and haplotypic frequencies were compared between patients and controls, patients with and without CALs, and patients resistant to and responsive to intravenous immunoglobulin (IVIG) treatment.

RESULTSThe T allele and T carriers of rs113420705 were significantly more common in KD patients than controls. A significant difference was also detected in haplotype distribution between patients and controls, where two haplotypes involving the T allele of rs113420705 showed higher frequencies in the patient group. Allelic and genotypic frequencies of the 3 SNPs were similar between patients with and without CALs and those resistant to and responsive to IVIG treatment.

CONCLUSIONOur results suggested that CASP3 probably plays an important role in KD. The T allele of rs113420705 may provide a useful marker for KD susceptibility, although no association between this SNP and clinical prognosis and treatment effect of KD has been found among the selected Chinese children patients.

OBJECTIVETo investigate whether adiponectin plays a role in the protection of myocardium in the rat myocardial ischemia preconditioning (IPC) model.

METHODInfarct size was measured by Masson's Trichrome staining, the expression of protein and mRNA of adiponectin at 0, 6, 12 and 24 h after IPC was examined by immunohistochemistry and quantitative real time RT-PCR, plasma levels of adiponectin at above mentioned four time points after IPC were detected by ELISA in IPC and MI rats.

RESULTInfarct size was smaller in IPC than in MI rats (20% ± 2% vs. 31% ± 3%, P < 0.05). The expression of adiponectin mRNA at 6 h and 12 h after IPC was 2.2 and 2.1 times higher than in Sham rats at respective time points (P < 0.05). Immunohistochemistry staining evidenced increased adiponectin expression in the ischemic area and weak expression of adiponectin in non-ischemic area (P < 0.05). Compared to the sham group, the plasma level of adiponectin increased significantly at 0, 6 and 12 h after IPC (0 h: 7.40 ± 0.47 vs. 10.90 ± 1.74; 6 h: 8.18 ± 1.41 vs. 10.98 ± 1.74; 12 h: 6.97 ± 1.02 vs. 9.31 ± 0.96, P < 0.05).

CONCLUSIONIPC reduced infarction size, upregulated the myocardial expression of adiponectin at mRNA and protein levels, and increased plasma adiponectin concentration, suggesting that the adiponectin may play a critical role in the protective effect of IPC.

OBJECTIVETo investigate the relationship between heat stress proteins 70 (HSPs70) gene polymorphism and the risk of acute mountain sickness.

METHODSFifty-six soldiers with acute mountain sickness and 173 soldiers without that were chosen as cases and controls. HSP70-1, HSP70-2 genotypes were analyzed by using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique.

RESULTSThe HSP70-1 polymorphism was similar in two groups. The genotype frequency of HSP70-2 B/B in acute mountain sickness group (23.2%) was significantly higher than that in the control (6.9%, P < 0.05, OR = 4.02).

CONCLUSIONThere is a significantly increased association of HSP70-2 B/B genotype with the risk of acute mountain sickness. Individuals with HSP70-2 B/B genotype may have weaker adaptive ability than those without this genotype under altitude stress. The results contribute to provide scientific bases for finding these individuals in specified occupational people, ensuring their health and enhancing work efficiency.

OBJECTIVEKawasaki disease (KD) is a form of acute multi-systemic vasculitis with unknown etiology. It is the leading cause of acquired heart disease in children due to the frequent occurrence of coronary artery lesions (CALs). Recently, a C allele of rs28493229 (G/C) in inositol 1,4,5-trisphosphate 3-kinase C (ITPKC) gene was found to significantly increase the risk for KD/CALs in Japanese population. It is important to confirm such finding in Chinese population to enable prognosis and personalized therapy for KD.

METHODSA case-control study was performed. The patient group has included 206 unrelated patients with KD, and the control group included 285 age, gender and ethnically matched children who never had KD. Genotyping of rs28493229 was performed using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and DNA sequencing. The allele, genotype and C allele carrier frequencies were compared between the two groups, patients with or without CALs, and patients who were resistant or responsive to (intravenous immunoglobulin, IVIG) treatment.

RESULTSFrequency of the C allele of rs28493229 was significantly lower in both groups than that in the Japanese population (P< 0.01). No significant difference was detected between the two groups in terms of allele, genotype and C carrier of rs28493229 frequencies. Such frequencies were also similar between patients with or without CALs, resistant or responsive to IVIG treatment.

CONCLUSIONOur study has failed to prove any association between rs28493229 and KD/CALs in Chinese patients, which indicated that the C allele of rs28493229 may not be used as a molecular marker for determining KD susceptibility, prognosis and effect of treatment. The much lower frequency of C allele does not support its significance in the occurrence of KD/CALs in Chinese population. It is still necessary to find functional SNPs in ITPKC gene which is associated with KD/CALs in Chinese population.
