Objective To evaluate the value of transabdominal sonography(TAS),transvaginal sonography(TVS),sonohysterography(SHG),and hysteroscopy(HS) in the detection of endometrial pathology in the patients with uterine cavity lesions. Methods Uterine abnormality and disease were routinely examined by TAS, TVS, SHG.Results TAS was performed in 88 cases,TVS in 45 cases,SHG in 39 cases,and HS in 23 cases.Comparison was made between different means,showing SHG and HS with the highest sensitivity,accuracy and positive evaluation,respectively as 94.29%, 90.24%, 94.29%,and 95.65%, 91.67%, 95.65%.Conclusions Transvaginal sonohysterography is an easy, accurate,econimical,painless and no-injury technique for detecting endomatrial pathology and endoluminal masses.

Objective To investigate the efficacy of high-dose ambroxol in elderly patients with aspiration pneumonias. Methods Totally 62 patients aged 65 years and over with aspiration pneumonia were enrolled into 2 groups:conventional-dose group intravenously given ambroxol 60 mg/d (n=30) and high-dose group received 270 mg/d (n=32).The times of remission and fever disappearance,rate of adverse effects,average duration of hospitalization,rates of mortality and recurrence within 2 months were observed. Results There were no significant differences in clinical charecteristics between the two groups.The times of remission and fever disappear ance and average duration of hospitalization were lower in high-dose group than in conventional-dose group [(3.2±0.6)d,(54.2±19.5)h,(12.7±4.1) d vs.(3.8±1.1)d,(66.5±18.4)h,(13.5±3.1)d,t=2.11,2.36,2.04,all P＜0.05].No differences were found in rates of mortality and recurrence within 2 months between the two groups (6.3％,3.1％ vs.10.0％,13.3％,x2=0.01,0.87,both P＞0.05).Adverse effects did not appear in the two dose groups. Conclusions High-dose ambroxol is efficient and safe for aspiration pneumonia in elderly patients.

Objective To assess the expression of thioredoxin reductase(TR)and thioredoxin (Trx)mRNA,TR activity in human placenta in women with preeclampsia,and to discuss the relationship between Trx system and the pathogenesis of preeclampsia.Methods Twenty-sixwomen with preeclampsia(10 mild and 16 severe)and 28 healthy gravidas (control) were included in this study.Semi-quantitative reverse transcription polymerase chain reaction(RT-PCR)were employed to demonstrate the expression of TR and Trx in placentas.TR activity was measured spectrophotometrically.Results The expression of TR mRNA(mild:0.865±0.018;severe:0.800±0.025,P＜0.05)and Trx mRNA(mild:0.873±0.008;severe:0.818±0.025,P＜0.05)were lower in placenta of preeclampsia than in the control group(TR mRNA:0.893±0.023;Trx mRNA:0.918±0.023.P＜0.05),and those levels in the severe preeclampsia group were lower than in the mild ones.Both the mild and severe preeclampsia groups showed lower TR activity than the control(mild:17.732±1.653;severe:15.626±1.543 vs 19.770±2.432,P＜0.05),and that of the severe preeclampsia group was lower than that of the mild ones.Positive correlation was found between the TR activity and TR mRNA expression in both groups(r=0.612,P＜0.001).Conclusions Abnormal decreased expression of TR mRNA and Trx mRNA and TR activity in human placenta of preeclampsia might participate and play an important role in the pathogenesis of preeclampsia.

Objective: To investgate the effects of NaCl stress on the growth and physiological characteristics of Thermopsis laceolata callus, and to reveal the physiological mechanism of T. laceolata under salty environment at the cellular level. Methods: The callus was cultured on the subculture medium with NaCl (0.2%-1.2%), and the contents of soluble sugar, soluble proteins, proline, and malondialdehyde (MDA) and the activities of superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT) were determined and analyzed. Results: The callus growth expressed a decreasing trend with NaCl concentration increasing (≤ 0.8%) but had no significant difference to contrast. Nevertheless, the callus grew very slowly with NaCl concentration increasing (> 0.8%); the contents of soluble sugar and free proline increased firstly and then decreased, but were higher than those of the control group; the content of soluble protein and the activities of SOD, CAT, and POD increased firstly and then decreased; MDA accumulated slowly at salinity (≤ 0.8% NaCl), then increased rapidly at salinity (> 0.8% NaCl). Conclusion: T. laceolata callus has an adaptability to salty environment (≤ 0.8% NaCl), and the callus could alleviate the salty injury by increasing the contents of the osmotic regulation substances, such as proline and soluble sugar, decreasing the osmotic potential, and increasing the activities of anti-oxidative enzyme.

OBJECTIVETo observe the effect of Zhenqing Recipe (ZQR) on non-alcoholic fatty liver (NAFL), and the expression of hepatic salt-inducible kinase 1 (SIK1) and sterol-regulatory element binding protein-ic (SREBP-lc) in type 2 diabetes rats.

METHODSA rat model of type 2 diabetes was established by high fat/sucrose diet combined with intraperitoneal injection of small dose streptozotocin (STZ) . Modeled rats were randomly divided into the model group, the ZQR group, and the metformin group, 8 in each group. Eight rats were recruited as a normal control group. ZQR at the daily dose of 12 g crude drugs/kg was administered to rats in the ZQR group by gastrogavage. Metformin suspension at the daily dose of 150 mg/kg was administered to rats in the metformin group by gastrogavage. Equal volume of distilled water was administered to rats in the normal control group and the model group. All medication lasted for 12 weeks. The levels of fasting blood glucose (FBG), free fatty acid (FFA), serum triglyceride (TG), serum total cholesterol (TC), serum alanine aminotransferase (ALT), and aspartate aminotransferase (AST) were detected. The body weight and wet liver weight were weighed, and the liver weight index calculated. The liver TG content was measured. The pathological changes of liver and the expression of SIK1 were observed by HE staining and immunohistochemistry. The mRNA and protein expression of SIK1 and SREBP-1c were detected using RT-PCR and Western blot.

RESULTSCompared with the normal control group, FBG, FFA, TG, TC, ALT, AST, liver weight index, and liver TG contents significantly increased (P < 0.01); liver steatosis was severe, the mRNA and protein expression of SIK1 obviously decreased (P < 0.01); mRNA and protein expression of SREBP-1c increased (P < 0.01). After drug therapy, compared with the model group, FBG, FFA, TG, TC, ALT, AST, and liver weight index significantly decreased, liver TG contents significantly decreased, the mRNA and protein expression of SIK1 obviously increased, while mRNA and protein expression of SREBP-1c obviously decreased (P < 0.05, P < 0.01) in the ZQR group and the metformin group (P < 0.05, P < 0.01); and the pathological changes were also improved. All the indices were improved more in the ZQR group (all P < 0.05).

CONCLUSIONIn this experiment, we found that the expression of SIK1 decreased in NAFL rats with type 2 diabetes. ZQR could alleviate lesion of NAFL type 2 diabetes rats possibly by up-regulating hepatic SIK1 expression at mRNA and protein levels.
