Objective To observe the antihypertensive effect of indapamide combined with enalapril on spontaneously hypertensive rats(SHRs).Methods Forty SHRs were randomly divided into 4 groups: control,indapamide,enalapril,and indapamide+enalapril(n=10 in each group).Medicine in varied doses was given to rats by intragastric administration.Variations of weight,heart rate and blood pressure were measured. Results Varied doses of medicine did not exert significant effects to the weight and heart rate of SHRs during and after the administration.In indapamide+enalapril group,the pressure of SHRs was significantly decreased with varied doses compared to that before the administration(P

OBJECTIVETo evaluate clinical outcomes of fixation for the treatment of radial head fracture with collapse of anterior articular surface.

METHODSFrom March 2006 to January 2013,17 patients with radial head fractures with collapse of anterior articular surface were analysed. According to the Mason classification, there were 12 cases with Mason type II fractures and 5 cases with Mason type III fractures. All the patients were treated with open reduction through posterolateral entrance of elbow joint and Herbert or titanium cannulated screw internal fixation.

RESULTSAll the patients were followed up, and the duration ranged from 6 to 18 months, with a mean of 11.3 months. According to the Broberg and Morrey score system, 2 patients got an excellent result, 12 good and 3 fair. There were no complications such as infection of elbow joint, nerve injury, non-union, traumatic osteoarthritis, heterotopic ossification and elbow instability. However, the postoperative activity range of elbow in the injuried side was less than that in the normal side.

CONCLUSIONRadial head fracture with collapse of anterior articular surface is easily misdiagnosed, and it can be treated with open reduction and internal fixation through posterolateral entrance.

OBJECTIVETo study the effect of Modified Dachengqi Decoction (MDD) as whole course therapy on mediators of inflammation in severe acute pancreatitis (SAP) model rats, and to compare interventional advantages over intestinal mucosal barrier (IMB) of SAP rats between whole course therapy of MDD and early stage therapy of MDD.

METHODSTotally 190 SD rats were divided into five groups according to random digit table, i.e., the sham-operation group, the model group, the octreotide (OT) group, the early stage MDD treatment group, the whole course MDD treatment group, 38 in each group. SAP models were established with retrograde injection of 5% sodium taurocholate into the pancreaticobiliary duct. Three hours after modeling normal saline (NS) was administered to rats in the sham-operation group and the model group by gastrogavage, once per 12 h.1.35 µg/100 g OT was subcutaneously injected to rats in the OT group, once every 8 h. 0.4 mL/100 g MDD was administered to rats in the early stage MDD treatment group, and 6 h later changed to NS (once per 12 h).0.4 mL/100 g MDD was administered to rats in the whole course MDD treatment group, once every 12 h. The accumulative survival rate and morphological manifestations of pancreas and small intestine were observed under microscope 48 h after modeling. Pathologic scores of the pancreas and small intestine were conducted at 4, 6, 24, and 48 h after modeling. Contents of serum amylase (AMY), alanine transaminase (ALT), and TNF-α were also detected. The expression of high mobility group box protein 1 (HMGB1) in the small intestine tissue was also detected by Western blot. The positive rate of bacterial translocation in mesenteric lymph nodes (MLNs) was observed within 48 h. Correlations between serum TNF-α or HMGB1 in small intestinal tissue and pathological scores of the pancreas or the small intestine were analyzed.

RESULTSThe accumulative survival rate was 100. 0% in the sham-operation group, 79. 2% in the whole course MDD treatment group, 70. 8% in the OT group, 45. 8% in the early stage MDD treatment group, and 37.5% in the model group. At 6 h after modeling, pathological scores decreased more in the whole course MDD treatment group, the early stage MDD treatment group, the OT group than in the model group (P < 0.05). At 24 and 48 h after modeling, pathological scores of the pancreas and the small intestine decreased more in the whole course MDD treatment group and the OT group than in the early stage MDD treatment group (P <0. 05). At 6, 24, and 48 h after modeling, serum contents of AMY and ALT both decreased more in the whole course MDD treatment group, the early stage MDD treatment group, the OT group than in the model group (P < 0.05). At 48 h after modeling serum contents of AMY and ALT both decreased more in the whole course MDD treatment group and the OT group than in the early stage MDD treatment group (P < 0.05). At 6 h after modeling serum TNF-α levels decreased more in the whole course MDD treatment group, the early stage MDD treatment group, the OT group than in the model group (P < 0.05). At 6, 24, and 48 h after modeling the level of HMGB1 in the small intestinal tissue decreased more in the whole course MDD treatment group, the early stage MDD treatment group, the OT group than in the model group (P < 0.05). Of them, HMGB1 levels at 24 and 48 h were lower in the whole course MDD treatment group and the OT group than in the early stage MDD treatment group (P < 0.05). The number of MLNs bacterial translocation at 48 h after modeling was lower in the whole course MDD treatment group and the OT group than in the early stage MDD treatment group and the model group (P < 0.05). Serum TNF-α contents within 6 h were positively correlated with pathological scores of pancreas (r = 0.579, P < 0.01). ROC curve showed that serum TNF-α contents could predict the severity of SAP (ROC = 0.990, 95% Cl: 0.971 to 1.000). HMGB1 in the small intestine was positively correlated with pathological scores of the small intestine (r = 0.620, P < 0.01).

CONCLUSIONSEarly stage use of MDD could effectively reduce the release of TNF-α, while whole course use of MDD could effectively inhibit the expression of HMGB1. The latter could preferably attenuate injuries of the pancreas and the small intestine, lower MLNs bacterial translocation, and elevate the survival rate.

Objective To observe the relationship of IL-10 gene single nucleotide polymorphism and the susceptibility to ALL. Methods The bone marrow and peripheral blood samples from 115 ALL patients and 323 healthy controls were collected in Peking University First Hospital and Beijing Dao-pei Hospital from January 2007 to December 2009. The DNA were extracted from all samples. The primers of -819C/T and -592A/C in the promoter region of IL-10 gene were designed for the PCR. The restrictive fragment length polymorphism of IL-10 gene was analyzed by using restrictive enzyme Msl Ⅰ and HpyCH4 Ⅲ.Sequencing was done in part of these samples to confirm the results of PCR. The differences of genotypes and allele ratio of -819 and -592 sites were analyzed between the ALL patients and healthy controls. Real-time quantitative PCR was performed to detect the EB virus (EBV) infection and the expression of BCR/ABL fusion gene. The differences of genotypes and allele ratio of -819 and -592 sites were analyzed between the positive and negative group. Results The genotype ratios of -819CC, -819TT, - 819CT, -592AA,- 592CC and - 592AC were 14. 8% ( 17/115 ), 45.2% ( 52/115 ), 40. 0% ( 46/115 ), 43.5% ( 50/115 ),16. 5% ( 19/115 ), 40. 0% ( 46/115 ) in ALL patients, and were 9. 9% ( 32/323 ), 16. 4% ( 53/323 ),73.7% ( 238/323 ), 11.8% ( 38/323 ), 15.5% ( 50/323 ), 72. 8% ( 235/323 ) in the healthy controls,respectively. The genotypes of -819 and -592 sites had statistically significant differences between the two groups(x2 values were 46.000 and 54.550, all P ＜ 0. 05 ). The allele ratio of -819T and -592A were (65.2%, 150/230) and (63.5%, 146/230) in ALL patients, while they were 53.5% (344/646) and 48. 1% (311/646)in the healthy controls. There were statistically significant differences between the two groups (x2 values were 9. 877 and 15.986, all P ＜ 0. 05 ). The EBV DNA were detected in 42 ALL patients,among which 22 were positive and 20 were negative. The genotype ratios of -819CC, -819TT, -819CT,-592AA, - 592CC, - 592AC in EBV positive group were 9. 1% ( 2/22 ), 40. 9% ( 9/22 ), 50. 0%(11/22) ,31.8% ( 7/22 ), 13.6% ( 3/22 ), 54. 5% ( 12/22 ), while they were 35.0% ( 7/20 ), 45.0%(9/20) ,20. 0% (4/20) ,35.0% (7/20) ,45.0% (9/20) ,20. 0% (4/20) in the EBV negative group. The genotypes of -819 and -592 sites showed no statistical differences between the two groups( all P ＞ 0. 05 ).The BCR/ABL fusion gene were detected in 36 ALL patients, among which 20 were positive and 16 were negative. The genotype ratios of - 819CC, - 819TT, - 819CT, - 592AA, - 592CC, - 592AC in BCR/ABL positive group were 0% (0/20) ,45.0% (9/20) ,55.0% ( 11/20), 45. 0% (9/20) ,5.0% (1/20) ,50. 0%( 10/20), while they were 18. 8% ( 3/16 ), 50. 0% ( 8/16), 31.3% ( 5/16 ), 50. 0% ( 8/16 ), 18. 8%(3/16), 31.3 % (5/16)in the BCR/ABL negative group. The genotypes of -819 and -592 sites showed no statistical differences between the two groups ( all P ＞ 0. 05 ). Conclusion The population with - 819TT and - 592AA genotype of IL-10 gene shows susceptibility to ALL.

The modern studies indicate that there is a close relationship between mast cells and the acupuncture effect, and acupuncture can activate mast cells to induce a series of vascular reaction and immunological effect. The authors hold that acupuncture is a kind of nociceptive stimulus, which can cause inflammatory reaction in the sites of acupuncture, and then further activate the nerve-endocrine-immune network to cause the cascade amplification of the acupuncture effect. The inflammatory reaction induced by acupuncture is one of the initial factors of acupuncture effect.

To investigate the influence of Anxin granules combined with tirofiban on acute myocardial infarction (AMI) Patients after elective percutaneous coronary intervention (PCI). One hundred and twenty AMI patients were randomly divided into treatment group and control group. The patients in the two groups were all given Tirofiban 30mins before PCI . The treatment group was added Anxin granules 30 mins before and after PCI. Tissue factor (TF) and von willebrand factor (vWF) were tested at 6 hours after operation. Syndromatology alteration of traditional Chinese medicine (TCM) and bleeding complications were observed at 4 weeks after operation. Both TF and vWF at 6 hours after operation of the treatment group was lower than the control group significantly (P < 0.01), while the condition of myocardial ischemia at 90 mins after operation of the treatment group was better than control group with significance. The syndromatology alteration of TCM especially spontaneous perspiration and hypodynamia of the treatment group were improved significantly compared to control group 4 weeks after operation. All patients in both groups had no bleeding complications and thrombopenia. The study suggests that Anxin granules combined with tirofiba can improve the clinical efficacy and the endothelial function of AMI patients after PCI with no increase in bleeding events.

OBJECTIVETo explore the effect of Qiling Decoction (QD) combined highly active antiretroviral treatment (HAART) on expression levels of peripheral blood Th17 and Treg cells in HIV/AIDS patients.

METHODSTotally 55 HIV/AIDS patients were randomly assigned to the treatment group (28 cases) and the combination group (27 cases). Besides, 21 HIV negative patients were recruited as the healthy control group. Those in the treatment group received HARRT alone, while those in the combination group received HAART combined QD. The observation lasted for 24 weeks. Meanwhile, according to peripheral blood CD4+ T cell counts before treatment, HIV/AIDS patients were assigned to three subgroups. For patients in subgroup 1, 1 cells/microL < CD4+ T cell counts < or = 100 cells/microL; For patients in subgroup 2, 101 cells/microL < CD4+ T cell counts < or = 200 cells/lL; For patients in subgroup 3, 201 cells/microL < CD4+ T cell counts < or = 350 cells/microL. Expression of peripheral blood Th17 and Treg cells, and number of CD4+ T cell counts were detected using flow cytometry (FCM)in HIV/AIDS patients at the pre-treatment baseline, week 4, 12, and 24, as well as those in the healthy control group.

RESULTSCompared with the healthy control group, CD4+ T cell counts and the baseline expression level of Th17 cells in the peripheral blood of HIV/AIDS patients significantly decreased, the expression level of Treg cells significantly increased P < 0.01). Compared with before treatment in the same group, CD4+ T cell counts all increased at week 4, 12, and 24 in the two treatment groups, showing statistical difference (P < 0.05, P < 0.01). There was no statistical difference in the effective rate at various CD4+ T cell levels between the two groups (P > 0.05). There was no statistical difference in expression levels of Th17 and Treg cells between the combination group and the treatment group at any time point (all P >0.05). The Th17/Treg ration significantly increased in the combination group after 24 weeks of treatment, showing statistical difference when compared with the treatment group (U = 2.135, P = 0.038).

CONCLUSIONQD could improve the immune balance of Th17/Treg cells, which might be one of its mechanisms for improving HIV/AIDS patients' immunity.
