Intraperitoneal glucose tolerance test was performed in the streptozotocin- and high fat-induced diabetic rats and normal rats.The results of RT-PCR and Western blot showed that the expression of 11?- hydroxysleroid dehydrogenase type 1 (11?-HSD1) was higher in the diabetic rats than that in control and was correlated with fasting plasma glucose,insulin and AUC-I/G with respective correlation coefficient (r) of 0.870, - 0.799,- 0.850,suggesting that increased expression of 11?-HSD1 appears to damage?-cell function through magnifying the local effect of glucocorticoids.

OBJECTIVETo explore the association between C825T polymorphism of G protein beta3 subunit (GNB3) gene and different Hilit types of essential hypertension (EH) in the Uygur nationality of Xinjiang.

METHODSAccording to Uygur medical theories, EH patients (as the EH group) and non-EH patients (as the control group) were assigned to four Hilit groups. The C825T polymorphism of GNB3 was detected in 161 EH patients and 379 non-EH subjects of different Hilit types by using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) to explore the difference of the genotypes and allelic frequencies and hypertension.

RESULTS(1) In Xinjiang Uygur population, the distribution frequencies of GNB3 C825T polymorphism were in accordance with Hardy-Weinberg (chi2 = 0.871, P = 0.647). (2) There was no statistical difference in the distribution frequencies of three genotypes and two alleles of GNB3 between the EH group and the control group (P > 0.05). (3) There was statistical difference in distribution frequencies of three genotypes between the abnormal Sapra and non-abnormal Sapra group (the sum of abnormal Sewda, abnormal Kan, and abnormal Balhem) (chi2 = 6.905, P = 0.032), especially between the abnormal Sapra and abnormal Balhem groups (chi2 = 10.404, P = 0.006), but there was no statistical difference in distribution frequencies of alleles between the two groups (P > 0.05). (4) In 161 EH patients, there was statistical difference in the distribution frequencies of three genotypes and two alleles between the abnormal Sapra and non-abnormal Sapra group (chi2 = 9.034, P = 0.011; chi2 = 4.701, P = 0.03).

CONCLUSIONSBoth TT genotype and T allele of GNB3 C825T polymorphism might not be associated with EH patients in Xinjiang Uygur populations. However, they were correlated with hypertension patients of non-abnormal Sapra, indicating the pathogeneses of EH with different Hilit types might be different.

Objective To further investigated the effect of minocycline on the inhibition of microglial activation and subsequent protection of nigral DA neuron.Methods 20 rats injected with LPS in the substantia nigra (SN) were randomly divided into two groups (LPS group and LPS+Minocycline group).The behavior was observed on the 7~(th) d and 14~(th) d.The immunohistoehemistry,in situ hybridization and Western-blot were used to detect the levels of positive neuron,mRNA,protein of TH and OX-42. Results The slightly rotational behavior was observed in LPS+Minoeyeline group.The majority of mieroglias were activated in the two groups.Some microglia in the SNpc remained ramified in LPS+ Minocycline group.The numbers of hypertophie microglia in LPS+Minoeyeline group were less than that in LPS group.Western-blot showed that the protein of OX-42 in two LPS groups was higher than in normal group(P

Objective:To investigate the therapeutic potential of therapeutic plasma exchange (TPE) combined with continuous venovenous hemofiltration (CVVH) in the treatment of children with severe sepsis and multiple organ dysfunction syndrome (MODS).Methods:It was a prospective randomized controlled study (RCT) involving 70 children with severe sepsis and MODS admitted to Anyang Maternal and Child Health Hospital from February 2019 to February 2023.According to random number table method, they were randomly divided into combination group (35 cases) and CVVH group (35 cases). Patients in the CVVH group were treated with CVVH alone, and those in the combination group were treated with TPE combined with CVVH.The antibiotic use time of the two groups was recorded and compared by the t test.The prothrombin time (PT), thrombin time (TT), partial prothrombin time (APTT), fibrinogen (FIB), and serum levels of interleukin (IL)-1β, IL-6, tumor necrosis factor-α (TNF-α), high mobility group protein B1 (HMGB1), Toll-like receptor 4 (TLR4) and soluble receptor (sFLT) levels before treatment and 48 h and 72 h after treatment were compared by the repeated measurement ANOVA for the overall comparison at multiple time points, and LSD- t test for pair-wise comparison.The 28-day survival of the two groups was recorded and compared by the Chi- square test. Results:The PT, TT and APTT at 48 h and 72 h after treatment were significantly lower in the combination group than those of CVVH group (all P<0.05). The FIB at 48 h[(2.15±0.42) g/L vs.(1.84±0.31) g/L]and 72 h after treatment [(2.89±0.27) g/L vs.(2.49±0.20) g/L]were significantly higher in the combination group than those of CVVH group (all P<0.05). The duration of antibiotic use in the combination group was significantly shorter than that of CVVH group [(11.33±1.16) d vs.(13.54±1.92) d, t=5.828, P<0.05]. Serum levels of IL-1β, IL-6 and TNF-α at 48 h and 72 h were significantly lower in the combination group than those of CVVH group (all P<0.05). Serum levels of HMGB1, TLR4 and sFLT at 48 h and 72 h were significantly lower in the combination group than those of CVVH group (all P<0.05). The 28-day survival of the combination group was significantly higher than that of CVVH group (94.29% vs.77.14%, χ2=4.200, P=0.040). Conclusions:TPE combined with CVVH can improve the coagulation function and inflammatory factor levels in children with severe sepsis and MODS, which may achieve therapeutic objectives by regulating the levels of HMGB1, TLR4 and sFLT, and improve the short-term prognosis.

OBJECTIVETo explore the diagnostic value of the measurement of serum Golgi protein 73 (GP73) in the diagnosis of hepatocellular carcinoma (HCC).

METHODSEnzyme-linked immunosorbent assay (ELISA) was used to detect the serum GP73 in the 81 cases of HCC, 71 cases of chronic hepatitis or cirrhosis (CH/LC) and 65 cases of healthy blood donors, and to evaluate the sensitivity and specificity in the diagnosis of HCC through the ROC curves.

RESULTSThe average levels of serum GP73 in HCC, CH/LC and Normal groups were (152.67 +/- 33.59) ng/ml, (93.15 +/- 20.02) ng/ml and (58.95 +/- 17.29) ng/ml(o) After calculating through the ROC curves, 120 ng/ml was set as the optimal cut-off point, GP73 has a sensitivity of 77.80% and a specificity of 78.00%.

CONCLUSIONSGP73 as a serum marker in the diagnosis of HCC had a higher sensitivity than AFP, and the combined detection of GP73 and AFP could improve HCC diagnosis.

OBJECTIVETo evaluate the accuracy and practicability of detecting viable myocardium by CARTO voltage mapping in swine model of acute myocardial infarction (MI).

METHODSMI was induced in 13 anesthetized swines via occluding the distal of left anterior descending coronary arteries by angioplasty balloon for 60-90 minutes. The viable myocardium detection by CARTO voltage mapping was made after reconstruction of the left ventricle using CARTO and the results were compared with TTC staining. The standard of CARTO voltage to detect viable myocardium was 0.5 - 1.5 mV while viable myocardium showed pink color by TTC staining.

RESULTSEleven out of 13 swines survived the operation and 2 swines died of ventricular fibrillation at 45 and 65 minutes post ischemia. Left ventricle was divided into 16 segments and 176 segments from 11 swines were analyzed. Viable myocardium detected by CARTO voltage mapping was identical as identified by TTC staining (Kappa = 0.816, P < 0.001). Taken the TTC result as standard, the sensitivity, specificity and accuracy rate of CARTO voltage mapping are 71.8%, 96.5% and 90.9% respectively.

CONCLUSIONCARTO voltage mapping could be used as a reliable tool to detect viable myocardium in this model.

OBJECTIVETo study the expressions of MMP-2 and TIMP-2 mRNA on cultured rat mesangial cells (MsC) and in human diseased glomeruli, and to explore their significance in the development of glomerulosclerosis.

METHODSThe expressions of MMP-2, TIMP-2, and Col IV mRNA on cultured rat MsC stimulated by IL-1 or/and TGF-beta1 were investigated through Northern blot analysis. The levels of MMP-2 and TIMP-2 mRNA expressions and immunoreactivity of PCNA and Col IV in human diseased glomeruli from renal biopsies of lupus nephritis (LN) patients were examined by in situ hybridization and immunohistochemistry, respectively.

RESULTSThe levels of MMP-2, TIMP-2, and Col IV mRNA expressions were markedly increased on cultured rat MsC stimulated by IL-1 or/and TGF-beta1. Meanwhile, upregulation of MMP-2 and TIMP-2 mRNA expressions was confirmed in diseased glomeruli from patients with various subtypes of LN, and was closely related to the positive cell number of PCNA presentation and deposition of Col IV in glomeruli.

CONCLUSIONThe results suggest that the over-expressions of MMP-2 and TIMP-2 mRNA on glomerular cells might play a critical role in the development of glomerulosclerosis.

OBJECTIVETo find anatomic basis for clinically modifying technique of harvesting superior and inferior gluteal artery perforator flap, in order to avoid muscle lossing in conventional superior and inferior myocutaneous flaps, keep the advantage such as large rich supplied volume soft tissue.

METHODS5 cases 10 sides adult cadaver were used to study the numbers, position, Course of superior and inferior gluteal artery perforators. The position of perforators was located by ultrasound Doppler in 6 cases and 12 sides in patient's superior and inferior gluteal area.

RESULTSSuperior and inferior gluteal artery originated from internal iliac artery. Several main perforators of large caliber were found in the paraischia and central portions of the gluteal muscle, its number was 10 - 15. The length of the vessels varies from 3 to 8 cm and their diameter from 1 - 1.5 mm. These significant perforators pass through the muscle itself and the fascial portion of the muscle to the overlying skin on the gluteal region. The dorsal branches of nervorum lumbalium perforate the deep fascia just above the iliac crest, lateral to the posterior superior iliac spine. If a nerve branch with a substantial diameter crosses the incision line, the nerve can be harvested within the flap. This nerve can be anastomosed to the anterior ramus of the lateral branch of the 4th intercostals nerve. In adult female, 3 - 5 perforators were located by ultrasound Doppler. They distributed in the triangle area among posterior superior iliac crest, the great trochanter and the coccyx.

CONCLUSIONSThe area and diameter of perforators of superior gluteal artery were relatively confirmed. It's possible to harvest the perforator flap without any muscle. It has the advantage of conventional myocutaneous flap with out of its disadvantages. It's easy to detect those perforator by ultrasound Doppler clinically. The nerve can be harvested and anastomosed simultaneously. Because the inferior gluteal area is a weight loading area, we suggested to use superior gluteal artery perforator flap. This flap can be transferred pedicled to treat sacral pressure sores or to be transferred freely for the breast reconstruction.
