OBJECTIVETo explore therapeutic effect and action mechanism of regulating spleen-stomach needling on diabetic nephropathy (DN).

METHODSUsing multi-centric, randomized, controlled and blind principles, 144 cases of DN were divided into an observation group and a control group according to random digital tab, 72 cases in each one. Based on regular treatment of diabetes, the regulating spleen-stomach needling was applied at Zhongwan (CV 12), Quchi (LI 11), Hegu (LI 4) and Xuehai (SP 10), etc. in the observation group while Shenshu (BL 23), Taixi (KI 3), Sanyinjiao (SP 6), Yanglingquan (GB 34), etc. were selected in the control group by reference of Acupuncture and moxibustion. The treatment was given twice a day, six days as a treatment session with interval of one day between sessions. Totally six weeks were required. Changes of clinical symptoms and signs, fast blood glucose (FBG), urinary albumin excretion rate (UAER), beta2-microglobulin (beta2-MG), monocyte chemotactic protein-1 (MCP-1), lymphocyte membrane cholesterol, propanediol (MDA), PCO, 8-hydroxydeoxy guanosine (8-OHdG), superoxide dismutase (SOD), CD3+, CD4+, CD8+, and CD4+/CD8+ were observed before and after treatment in two groups.

RESULTSAs for improving clinical symptoms and signs, total effective rate was 84.29% (59/70) in the observation group and 55.56% (40/72) in the control group, which had statistical difference between two groups (P<0.01). As for regulating glycometabolism [(6.25 +/- 0.32) mmol/L vs (8.09 +/- 0.63) mmol/L], reducing UAER [(154.43 +/- 55.14) mg/24h vs (268.91 +/- 77.65) mg/24h], restraining over-expression of MCP-1 [(137.59 +/- 36.15) pg/mL vs (166.89 +/- 42.82) pg/mL], regulating level of oxidative stress, prohibiting oxidation of protein and adjusting quantity and activity of T lymphocyte subgroup, the observation group was superior to the control group (P< 0.05, P<0.01).

CONCLUSIONThe regulating spleen-stomach needling is an effective method for treatment of DN, which cold improve glycometabolism disturbance-induced progressive kidney injury, recover glomerular filtration, reduce urinary albumin excretion rate, restrain overexpression of MCP-1, adjust level of oxidative stress, prohibit oxidation of protein, increase protectiveness of membrane, adjust quantity and activity abnormity of T lymphocyte subgroup, leading to repairing lymphocyte damage and improving immune expression to delay kidney damage.

Objective To observe the expressions of bone morphogenetic protein-2(BMP-2)and bone morphogenetie protein-7(BMP-7)in the synovial tissue of fluorosis rats and its correlation with pathogenic mechanism of fluorosis arthritis.Methods Thirty-two SD rats were randomly divided into 4 groups:the control group,low,moderate and high-dose fluoride group.The control group ate commou fodder.The low,moderate and high dose fluoride group were fed with fodder composed of 25%.35%and 68%of corn(containing fluorine of 148.00 mg/kg)in chronic endemic fluorosis region in Guizhou Province.After 140 days,the expressions of BMP-2 and BMP-7 protein were determined by immunohistochemistry and assayed the absorbanee by computer image-pattern analysis system.Light microscope was used to observe the synovial tissue by Hematoxin Eosin,and calculated the pathological integral of synovium according to pathological grade standard.Results The expressions of BMP-2 (32.50±2.73)and BMP-7(38.90±2.56)in the control group was spare.Compared with the control group,the expressions of BMP-2(59.43±5.12,79.82±6.41,101.76±7.56)and BMP-7(55.10±4.82,78.42±5.61,98.46± 6.05)in the synovial tissue was up-regulated in each experimental groups(P＜0.05),especially in the moderate dose and the high-dose groups(P＜0.05).Compared with the control group(0.54±0.21).the pathological integral of synovium increased(P＜0.05)in each experimental groups(1.04±0.98,4.69±1.28,8.60±2.07).The expressions of BMP-2 and BMP-7 in the synovial tissue was found to be positively related with the pathological integral of synovium(r=0.98,0.99,P＜0.05).Conclusion The BMP-2 and BMP-7 play an important role in the development of fluorosis arthritis,probably by affecting osteogenesis.

OBJECTIVETo explore the clinical characteristics of cataract surgery after radial keratotomy (RK) and appropriate calculation of intraocular lens (IOL) power.

METHODSEight patients with cataract (12 eyes) after RK were treated in our hospital from March, 2010 to June, 2013. The visual acuity, keratometric power and length of the ocular axis were examined before the operation. For each patient, 3 groups of corneal curvature values were measured using a automatic keratometer (TOPCON-KR8800) and the minimal K value was selected. Myopic or hyperopic posterior chamber IOL (-1.00 to -2.00 D) were selected based on automatic calculations with SRK-T. Phacoemulsification and IOL implantation were then performed, and the patients were followed up for visual acuity and refractive statuses at 3 months after the operation.

RESULTSAll the 12 operated eyes showed improved visual acuity after the operation. The uncorrected visual acuity reached 0.8 to 1.0 in 6 eyes and 0.4 to 0.6+ in the other 6, with a corrected visual acuity ranging from 0.6 to 1.0. The refractive status after operations was nearly emmetropic (+0.75 to -1.00 D) in 6 eyes and myopic in the other 6 (-1.00 to -2.50 D).

CONCLUSIONSPhacoemulsification and IOL implantation is feasible in cataract patients with previous RK. Selecting the minimal K values for central corneal curvature and calculation of the IOL power using the SRK T equation with a reservation of -1.00 to -2.00 D can better ensure the safety of the procedure and avoid the occurrence of hyperopia >+3.00D.

OBJECTIVETo investigate whether the polymorphism of DNA repair genes XPC (Ala499Val and Lys939Gln) and XPG (His1104Asp) is associated with the susceptibility to hepatocellular carcinoma (HCC).

METHODSA hospital-based case-control study was conducted in 500 cases with HCC and 507 controls. Genotypes of XPC and XPG were determined by real-time polymerase chain reaction with the TaqMan MGB probe.

RESULTSCompared to the CC genotype, the CT genotype and the TT genotype of XPC Ala499Val were not associated with the susceptibility to HCC (adjusted OR = 1.34, 95% CI: 0.85-2.12; adjusted OR = 1.30, 95% CI: 0.68-2.51, respectively). Compared to the AA genotype, the AC genotype and the CC genotype of Lys939Gln were not associated with the susceptibility to HCC (adjusted OR = 1.20, 95% CI: 0.78-1.85; adjusted OR = 1.81, 95% CI: 0.88-3.73, respectively). Compared to the CC genotype, the CG genotype and the GG genotype of XPG His1104Asp were not associated with the susceptibility to HCC (adjusted OR = 0.85, 95% CI: 0.56-1.27; adjusted OR = 1.12, 95% CI: 0.67-1.87, respectively) However, the stratified analysis revealed that the females with the AC+CC genotype of XPC Lys939Gln had increased risk of HCC compared to those with AA genotype (OR = 2.17, 95% CI: 1.01-4.64).

CONCLUSIONOur results suggest that XPC and XPG polymorphisms do not independently affect on the susceptibility to HCC, but the joint effect of C allele of XPC Lys939Gln and female may modify the risk of HCC.

Objective To observe the management and outcome of the cardiac tamponade patients during the ablation procedure using two different anticoagulation strategies. Methods All the patients developed tamponade during the ablation procedure were enrolled from January 2007 to December 2013 in our center. In group 1, warfarin was discontinued 3 to 5 days before the procedure and low molecular weight heparin (LMWH) was administered subcutaneously until ablation procedure day. In group 2, warfarin was not discontinued and the international normalized ratio INR was to maintained between 2 and 3. Results There were 27 patients (0.6%) developed cardiac tamponade out of a total 4487 patients received ablation in our center. The baseline clinical characteristics including age, left atrium, the heparin dose and ACT during the procedure had no signiifcant difference between the groups, except that the INR was higher in the group 2 (0.9±0.1 vs. 2.3±0.5, P<0.001). There was no signiifcant difference in the amount of pericardiac drainage between the two groups (365±222 ml vs. 506±300 ml, P=0.137). Two patients in group 1 patient (11.1%) and 1 in group 2 (11.1%) needed emergency surgical repair (P>0.999). The median hospital day was similar in the 2 groups [(9.6±3.3) d vs. (12.1±4.5) d, P=0.167]. There were no other serious complications and no hospital death. Conclusions Non-discontinuation of warfarin during peri-procedural catheter ablation of AF is not signiifcantly different to bridging with LMWH in the management and outcome of acute cardiac tamponade.

Objective Identify the mechanism of induced atrial arrhythmias after pulmonary vein isolation (PVI) in patients with paroxysmal atrial ifbrillation(PAF), and investigate its long-term prognosis. Methods All patients with PAF undergoing PVI and induction test afterwards between Feburary 2010 and October 2010 were included. The induction protocol was rapid pacing initiated at cycle length of 250 ms with progressive shortening in a decrement of 10 ms down to 180 ms or refractoriness. Isoproterenol of 2-4μg/min was administrated as well. Inducibility was deifned as induction of atrial arrhythmia lasting >1 min. The mechanism of induced tachycardia was identiifed by activation mapping and entrainment mapping under the guidance of CARTO system. All patients were followed up by 36 months. Results Forty-nine atrial tachycardia were induced in 39 (19.7%) patients, including 35 organized atrial tachycardia (OAT) and 14 atrial ifbrillation (AF). The LA diameter was signiifcantly larger in inducible group than non-inducible group (39.5±6.6 mm vs. 36.7±5.2 mm, P=0.004). Macroreentry was the most common mechanism in induced OATs (28, 80.0%), and mitral isthmus was the most common critical site (20, 40.8%), followed by cavo-tricuspid isthmus (12, 24.5%), PV (6, 12.2%), LA septum (4, 8.2%), superior vena cava (3, 6.1%) and LA roof (1, 2.0%). Conclusions The most common mechanism of induced tachycardia by IV isoproterenol and rapid pacing is MI and CTI dependent after PVI in PAF patients, which can be succssefully eliminated by liner ablation, not increasing long-term recurrence rate.

OBJECTIVETo investigate the expressions of PPAR-gamma/PGC-1alpha and Nrf2/gamma-GCS-h in lung of guinea pigs with bronchial asthma, and to explore the roles of them.

METHODSForty adult male guinea pigs were randomly divided into 4 groups: the control group (group A), asthmatic group ( group B), dexamethasone group (group C) and rogridone group (group D), 10 guinea pigs in each group. The asthmatic model was established by the ovalbumin challenge method. Expressions of PPAR-gamma/PGC-1alpha and Nrf2/gamma-GCS-h mRNA in lung tissue were assayed by in situ hybridization. Expressions of PPAR-gamma/PGC-1alpha and Nrf2/gamma-GCS-h protein were detected by immunohischemistry and by Western blot.

RESULTSIn situ hybridization showed that the expressions of PPAR-gamma/PGC-1alpha and Nrf2/gamma-GCS-h mRNA in lung tissue were the lowest in group B and the comparison among groups showed statistical significant (all P < 0.01). Immunohistochemistry and Western blot indicated that the value of PPAR-gamma/PGC-1alpha and Nrf2/gamma-GCS-h protein in lung tissue were the lowest in group B, and expressed primarily in nucleus, the differences being statistically significant (all P < 0.01). There was positive correlation between PPAR-gamma and PGC-1. gamma-GCS-h mRNA also positively correlated between PPAR-gamma/PGC-1alpha and Nrf2 in nucleus, and the expression of Nrf2 was also positively correlated with PPAR-gamma/ PGC-1alpha.

CONCLUSIONIn acute asthmatic models induced by ovalbumin, the expressions of PPAR-alpha/PGC-1alpha and Nrf2/gamma-GCS-h were decreased, and PPARgamma/PGC-1alpha could up-regulate the expressions of Nrf2/gamma-GCS-h to increase the antioxidant defense of tissues, thus being implicated that PPARgamma/PGC-1alpha might play important roles in the pathogenesis and prevention of asthma.
