40/h) and non-severe group(n=15,AHI 5-40/h).Anthropometric measurements,fasting plasma glucose,insulin,blood fat,and CT quantitative measurement of abdominal adipose tissue were recorded. Results Insulin resistance index(HOMA-IR) in patients with OSAS was related to hypoxia independently of obesity variables.The severe group was characterized by more serious metabolic disorders and higher prevalence of metabolic syndrome than the non-severe group.OSAS was positively associated with an increased metabolic disorders risk for the severe group versus the non-severe group(OR=8.8).Using the receiver operating characteristic(ROC) curve analysis,waist circumference had the greatest areas under the ROC curves compared with body mass index and neck circumference.The results of multiple stepwise regression of lowest pulse oxygen saturation(LSpO2)during overnight sleep indicated that neck circumference followed by epworth sleepiness score(ESS) entered the equation(P

Objective To investigate the effect of preoperative nursing intervention in the prevention of postoperative retention of urine of patients after total knee arthroplasty. Methods 128patients underwent total knee arthroplasty were divided into the intervention group and the control group (64 cases in each group) by random number table.The patients in the control group received routine nursing care and the patients in the intervention group accepted preoperative nursing intervention 3 to 5 days before surgery. The incidence of post-operation urinary retention, catheterization, satisfaction degree and compliance of the patients were compared between the two groups. Results The incidence rate of post-operation urinary retention and catheterization of the patients was respectively 15.6%(10/64) and 7.8%(5/64) in the intervention group,lower than 34.4%(22/64) and 23.4%(15/64) in the control group. The difference was statistically significant (χ2=6.00, 5.93, respectively, P<0.05). The satisfaction degree and compliance of patients were respectively 95.3%(61/64) and 75.0%(48/64) in the intervention group, higher than 85.2%(52/64) and 31.3%(20/64) in the control group,the difference was statistically significant (χ2=6.12, 24.60,respectively, P < 0.05). Conclusions Preoperative nursing intervention have good effect in the prevention of postoperative retention of urine and improving satisfaction degree of patients underwent total knee arthroplasty.

OBJECTIVETo investigate the role of CCL28 in hypoxia-induced cell migration of hepatocellular carcinoma (HCC).

METHODSResected liver tissues from 50 HCC patients were subjected to real-time (rt)-PCR analysis to evaluate the mRNA expression levels of the hypoxia-induced factor HIF-1a and the chemokine CCL28. Patient data on treatment and outcome were analyzed. The human HCC cell lines HepG2 and HCCLM3 were used to investigate effects of hypoxic conditions on HIF-1a and CCL28 expressions by rt-PCR, western blotting, and enzyme-linked immunoassay. The CCL28-mediated effects of hypoxic conditions on cell mobility and invasion were assessed by trans-well and matrigel assays, respectively, in HCCLM3 with CCL28 expression silenced by small-interfering (si)RNA transfection. Spearman's rank test was used to assess the correlation between CCL28 and effects on disease- and treatment-related factors.

RESULTSThe mRNA levels of CCL28 (0.025 +/- 0.075) were found to be strongly correlated with HIF-1a(0.065 +/- 0.098) in human clinical samples of HCC (r = 0.595, P less than 0.01), with higher expressions of both related to recurrence after surgery (P = 0.011 and 0.019, respectively). In vitro hypoxic conditions stimulated HIF-1a and CCL28 expression in a time-dependent manner in both HepG2 (HIF-1a: F = 873.5; CCL28: F = 151.6) and HCCLM3 (HIF-1a: F = 964.5; CCL28: F = 285.8) (all P less than 0.01). siRNA inhibition of CCL28 in HCCLM3 cells led to a significant reduction in hypoxia-induced invasion and migration (all P = 0.011).

CONCLUSIONChemokine CCL28 expression is up-regulated in human HCC and under in vitro hypoxic conditions, and may play an important role in hypoxia-induced HCC migration and invasion.

Objectives:To observe the changes of the tongues in rats with blood-stasis syndrome induced mainly by cold. To explore the evidence that tongues were the target of blood stasis syndrome and the target of medication. Methods: Rats with blood-stasis syndrome induced by cold (BSC group) were dipped into ice water (0 ℃) for 5 minutes every day and lasted 20d individually. Different drugs were given orally after the model establishment. And then we took photos of tongues of all rats by digital camera, analyzed the gray scale value of all rats' tongues using image analysis software, and observed the capillaries in tongues by electron microscope. Results: The tongues of rats which had been frozen in ice water for 20 d (once a day) were dark purple, the same as that of models induced by chemical materials .While as for the normal rats, the tongues were lustrous and ruddy. The changes of color of the tongues persisted about 1 week and were great obvious at the 3rd day after the model establishment among different time-points. After given different drugs, the degree of dark purple tongue degraded, showed significant difference (P < 0.01) from that of model rats. The capillary stegnosis and nucleus turgescence of vascular endothelial cell were observed in tongues in BSC group by using electron microscope. After medication, the above changes recovered. Conclusion: The degree of dark purple tongue indicates the degree of diseases with blood-stasis syndrome. The tongue probably is a target of drug treatment.

OBJECTIVE To observe the effect of baicalin on Aβ25-35 induced learning and memory deficits and changes in autophagy-related genes in mice so as to explore the related mechanisms of Alzheimer disease (AD) treatment . METHODS C57 mice were administered with 3μL Aβ25-35 3 mmol·L-1 by intracerebroventricular injection to establish an AD model. Baicalin was given by intracerebroventricular injection at the dose of 25, 50 and 100 mg · kg-1 for 15 d, respectively. The total distance and the central grid residence time were measured in the open-field test. The escape latency and the time to reach the platform were monitored in the Morris water maze trial. The autophagic vacuoles in the hippocampus of the mice were observed by transmission electron microscopy before the protein expressions of microtu?bule-associated protein 1 light chain 3 (LC3) and Beclin1 in brain tissue were analyzed by Western blot?ting assay. RESULTS Intracerebroventricular injection of Aβ25-35 could reduce the total distance from (3984±321)cm to (2790±306)cm and extend central grid residence time from (3.6±1.2)s to (8.8±2.9)s in the open-field test. The escape latency of water maze also increased from (22.0 ± 1.9)s to (38.8 ± 2.2)s. Autophagic vacuoles or late autophagic vacuoles and increased Beclin1 and LC3 and protein level were observed in the hippocampus after Aβ25-35 injection. Intraperitoneal injection of Baicalin 50 and 100 mg · kg-1 for fifteen consecutive days extended the total distance in open-field test to (3705 ± 337)cm and (3968 ± 448)cm, respectively, while the central grid residence time was reduced to (5.6 ± 1.8)s and (3.9±1.5)s, respectively. The total time taken to reach the platform in water maze test was reduced to (28.6± 1.9)s, (22.9 ± 1.7)s. Mitochondrial swelling, vacuolar membrane structure or autophagic vacuoles were visible in the hippocampus. LC3 and Beclin1 protein expression was significantly up-regulated(P<0.01). CONCLUSION Baicalin shows protective effect against Aβ25-35 induced learning and memory deficits, and this effect may be related to the activation of autophagy in the mouse hippocampus.

OBJECTIVETo quantitatively analyze the effect of modified Biejiajian Pill (BJJP) on the pathological change and degree of albumin induced immune hepatic fibrosis in rats.

METHODSRats were immunized by multiple subcutaneous injections of human serum albumin (8 g/L) , and were medicated in groups respectively after antibody producing, BJJP high-dose (13 g/kg) group, medium-dose (6.5 g/kg) group, low-dose (3.25 g/kg) group, the model group, colchicines (1.0 mg/kg) group, and Ganpikang (22.23 mg/kg) group. Then, caudal vein injection of albumin was given 40 min after medication to induce liver fibrosis. Animals were sacrificed finally to observe the pathological change, and the distribution and content of collagen and plastin were determined quantitatively with HE and Masson stain.

RESULTSBJJP high-, medium-, and low-dose groups could obviously improve the pathological change of the hepatic fibrosis rats (decreasing rate of the total score was 62.50%, 40.75%, and 8.33%, respectively), and the content of collagen reduced markedly (P<0.05, P<0.01).

CONCLUSIONBJJP can effectively prevent and reduce the pathological change of albumin induced immune hepatic fibrosis in rats.

OBJECTIVETo investigate the distribution of estrogen receptor beta (ERbeta) gene polymorphisms between the Uygurs and the Hans in Urumqi and the association of the polymorphisms with intrahepatic cholestasis of pregnancy (ICP).

METHODSICP cases and controls from a hospital were recruited from April 2008 to April 2011,and a total of 105 ICP patients in Uygurs case group and 105 ICP patients in Hans case group were randomly selected, meanwhile, 105 Uygurs and 105 Hans healthy pregnant women were recruited as control group. The distribution of Rsa I and Alu I of ERbeta gene polymorphism were analyzed by PCR amplification and restriction and other molecular biology approaches. Data were analyzed by chi2 and Fisher exact probability.

RESULTSIn Uygurs case group, the genotype frequencies of rr, Rr,RR,aa, Aa and AA were 39.0% (41 cases), 50.5% (53 cases), 10.5% (11 cases), 62.7% (66 cases), 30.5% (32 cases), 6.8% (7 cases). In Uygurs control group, the frequencies were 21.0% (22 cases), 56.2% (59 cases), 22.8% (24 cases), 80.0% (84 cases), 18.1% (19 cases), 1.9% (2 cases). In Hans case group, the genotype frequencies of rr, Rr, RR, aa, Aa and AA were 40. 0% (42 cases), 45.7% (48 cases), 14.3% (15 cases), 66.7% (70 cases), 29.5% (31 cases), 3.8% (4 cases). In Hans control group,the frequencies were 29.5% (31 cases), 57.2% (60 cases), 13.3% (14 cases), 74.2% (78 cases), 23.8% (25 cases), 2.0% (2 cases). The genotype frequencies were not statistically significant between the two case groups and between the two control groups (all P values > 0.05), and between two Hans groups (P > 0.05). The frequencies of RRaa in the Uygur case group was lower(4. 76% ,5 cases)than control group (13.33%, 14 cases) (P <0.05), while the frequencies of rrAa in the Uygur case group was significantly higher (14. 29% ,15 cases)than control group (2.86%, 3 cases) (all P values < 0.05).

CONCLUSIONThe distribution of ERbeta gene polymorphism is of no significant difference between the Uygurs and Hans, ERbeta gene polymorphism may correlate with pathogenesis of ICP in the Uygurs other than in the Hans, and rrAa might be risk factor for ICP in the Uygurs.

OBJECTIVETo study the prognosis of childhood asthma and the factors influencing asthmatic attacks and prognosis.

METHODSThe medical data of 212 children with asthma who were followed up for more than 5 years were retrospectively studied.

RESULTSDuring the 5-year follow up, asthmatic attacks termination was found in 121 cases (57.1%) and asthma persistence was observed in 91 cases. Respiratory tract infections were found as the major factors inducing asthmatic attacks (71.7%), followed by inhaled allergens (17.0%).The children with asthma induced by respiratory tract infections had a higher remission rate of asthmatic attacks (61.2%) than those induced by allergens (41.7%) or exercises (26.3%). Three risk factors for asthma persistence were identified: concurrent allergic rhinitis and eczema, parental asthma and allergy-induced wheezing.

CONCLUSIONSThe 5-year follow-up study demonstrated that asthmatic attacks stopped in the majority of children with asthma. Respiratory tract infections may be the major factors inducing acute asthma attacks. The children with asthma induced by respiratory infections may experience a better outcome. Atopic children or children with the genetic background of atopy are at high risks for the development of persistent asthma.
