OBJECTIVE: To investigate the protective effects of Chaiqin Chengqi Decoction (CQCQD), a compound traditional Chinese herbal medicine, on acinar cells and the changes of intracellular calcium concentration ([Ca(2+)]i) in acute pancreatitis (AP) rats. METHODS: CQCQ serum (CQCQS) was prepared by intragastric administration of CQCQD in SD rats, and AP was induced in SD rats by biliary-pancreatic duct ligation method. Pancreatic acinar cells were isolated by collagenase digestion and co-incubated with the drug serum containing CQCQD in vitro, then cell viability was determined by methyl thiazolyl tetrazolium (MTT) method and intracellular fluorescent intensity (FI) was observed and analyzed to investigate the changes of intracellular calcium concentration ([Ca(2+)]i). RESULTS: Both 5% and 10% CQCQS could improve the viability of pancreatic acinar cells in AP rats (P<0.05), and 10% CQCQS was more effective than 5% CQCQS (P<0.05). [Ca(2+)]i was elevated in AP rats (P<0.05), while the level of [Ca(2+)]i elevation was reduced after CQCQS treatment (P<0.05). CONCLUSION: CQCQD has a protective effect on pancreatic acinar cells of AP rats, which may be associated with its inhibition effect on intracellular calcium overload.

Patients with systemic lupus erythematosus (SLE)are susceptible to influenza virus infection due to autoimmune disorder,use of glucocorticoids and the immunosuppressive agents.Influenza virus infection affects the disease stability,and the mortality of influenza virus infection in SLE patients is 5 times higher than that in general people infected by influenza virus.Vaccination is the most effective measure to prevent influenza virus infection.There is lack of studies on the influenza immunization in SLE patients in China,so this paper reviews prevention effect and safety of inoculation,the immune response to vaccine as well as the factors influencing immune response in influenza vaccination for SLE patients.

OBJECTIVE:To compare the efficacy and safety of Jinkui shenqi pill versus Shengjing capsule in the treatment of oligoasthenozoosperimia under behavioral intervention. METHODS:98 patients with oligoasthenozoosperimia were randomly divid-ed into Shengjing capsule group(49 cases)and Jinkui shenqi pill(49 cases). All patients received intervention treatment(cognitive intervention,psychological intervention,diet intervention and exercise intervention,etc.). Based on it,Shengjing capsule group re-ceived 1.6 g Shengjing capsules,orally,3 times a day;Jinkui shenqi pill group received 6 g Jinkui shenqi pill,orally,twice a day. They were treated for 3 months. Clinical efficacy,semen quality (semen volume,sperm concentration,sperm motility rate, sperm motility)and sex hormone levels [testosterone(T),follicle stimulating hormone(FSH),luteinizing hormone(HLH),pro-gesterone(P),prolactin(PRL)] before and after treatment,and the incidence of adverse reactions in 2 groups were observed. RE-SULTS:The total effective rate in Shengjing capsule group was significantly higher than Jinkui shenqi pill group,with statistical significance(P<0.05). Before treatment,there were no significant differences in semen quality and sex hormone levels(P>0.05). After treatment,semen quality in 2 groups was significantly higher than before,semen volume and sperm motility in Shengjing cap-sule group were higher than Jinkui shenqi pill group,with statistical significances(P<0.05). T levels in 2 groups were significant-ly higher than before,while Shengjing capsule group was lower than Jinkui shenqi pill group,with statistical significances (P<0.05);and there were no significant differences in FSH,HLH,P and PRL before and after treatment in 2 groups(P>0.05). And there was no significant difference in the incidence of adverse reactions(P>0.05). CONCLUSIONS:Under behavioral interven-tion,Shengjing capsule has better efficacy than Jinkui shenqi pill in the treatment of oligoasthenozoosperimia,it can significantly improve semen quality,while Jinkui shenqi pill is better in terms of improving sex hormone levels;and both show good safety.

OBJECTIVE: To investigate the therapeutic effect of Yihuo Qingxia method, a traditional Chinese medicine therapeutic method for replenishing qi to activate blood, clearing away heat and dredging intestines, in treating hyperlipoidemia-related severe acute pancreatitis (SAP) in early stage. METHODS: One hundred and four patients with hyperlipoidemia-related SAP were divided into two groups: early group (admitted to hospital within 3 days after onset) and late group (admitted to hospital from 3 days to 7 days after onset). There were 52 cases in each group. All the patients were treated by Yihuo Qingxia method. RESULTS: There were no statistical differences in 48-hour Ranson scores, CT scores, 24-hour acute physiology and chronic heath evaluation II scores (APACHE II scores), and the levels of 24-hour serum triglyceride (TG) and serum glucose in the two groups (P>0.05). At the 10th day after onset, the serum TG level in early group was lower than that in late group (P<0.01). The incidences of acute respiratory distress syndrome, acute renal failure, hepatic inadequacy, congestive heart failure, shock, encephalopathy, infection and alimentary tract hemorrhage in early group were higher than those in late group (P<0.05). The mortality in early group was lower than that in the late group (P<0.05). The length of hospital stay in early group was shorter than that in late group (P<0.05). CONCLUSION: Yihuo Qingxia method has a good efficacy in treating hyperlipoidemia-related SAP in early stage.

To investigate the prognostic effects of integrated traditional Chinese and Western medicine therapy without antibiotics in treatment of patients with severe acute pancreatitis (SAP).

The serum level of CXCL10 was determined in both patients with Graves' disease (GD) and normal control subjects.Serum CXCL10 levels in untreated and relapsed GD groups were higher compared with the remission group and control group( P＜0.01 ).A significant difference was observed between the former two GD groups (P＜0.01 ),but no difference was found between latter two groups( P＞0.05 ).Serum CXCL10 levels were positively correlated with FT3 and FT4,and negatively correlated with TSH by multiple linear regression analysis( P＜0.01 ).

OBJECTIVE: To investigate the mechanism of Chaiqin Chengqi Decoction (CQCQD), a compound of traditional Chinese herbal medicine, acting on the pancreatic acinar cell calcium overload in rats with acute pancreatitis (AP). METHODS: A total of 30 SD rats were randomly divided into normal control group, untreated group and CQCQD group (n=10, respectively). AP was induced in rats by caerulein (5x50 mug/kg) intraperitoneal injection within 4 h. The pancreatic tissue SERCA1 and SERCA2 mRNA expressions were detected by fluorescent quantization polymerase chain reaction method; intracellular calcium fluorescence intensity (FI) of pancreatic acinar cells and the pancreatic pathological score were measured by laser scanning confocal microscopy and light microscopy respectively. RESULTS: There were no SERCA1 mRNA expressions in pancreatic acinar cells of rats in the normal control group and the untreated group. The expression of pancreatic SERCA2 mRNA in the untreated group was down-regulated compared with that in the normal control group (expression ratio=0.536; P=0.001); the expression of pancreatic SERCA2 mRNA in the CQCQD group was up-regulated compared with that in the untreated group (expression ratio=2.00; P=0.012). The pancreatic pathological score in the CQCQD group was lower than that in the untreated group and the FI of Ca(2+) was also lower. CONCLUSION: CQCQD can up-regulate the expression of pancreatic SERCA2 mRNA, release the calcium overload, and hence reduce the pathological changes in pancreatic tissue.

Seventy-three patients with type 2 diabetes mellitus were divided into atheroselerosis(AS) group and non-AS group according to the intima-media thickness(IMT)of the carotid artery.The plasma visfatin level in AS group was higher than that in non-As group[(44.95±10.14 vs 34.52±9.08)μg/L,P<0.05],and both of them were higher than that of the control [(24.46±7.18)μg/L,both P<0.05 ].The visfatin level Was positively correlated with IMT,waist-to-hip ratio,visceral fat thickness,fasting insulin,and HOMA insulin resistance index.Age,duration of diabetes,HbA_(1C),and visfatin level were the major risk factors for IMT of the carotid artery.
