BACKGROUND: Multiple applications of opium medicines can induce the accommodative changes of morphology and function in some intracerebral nerve positions. These accommodative changes are important neurobiological bases inducing drug-desire and re-addiction after detoxification. However, the actual molecular mechanism is unclear at present.OBJECTIVE: To investigate the impacts of the generation of heroin-dependence and detoxification on brain-derived neurotrophic factor (BDNF) in rat to provide a laboratorial gist for the participation of BDNS in heroin-dependence and detoxification.DESIGN: A randomized controlled study by employing experimental animals as subjectsSETTING: Mental health center of a medical university affiliated hospital MATERIALS: The study was conducted in the Laboratory of Pharmacology,Faculty of Pharmacology, Chongqing Medical University between March 2004and July 2004. Totally 30 inbreeding clean male SD rats with a bodymass between 200 g and 250 g were obtained from the Experimental Animal Center of the Third Military Medical University of Chinese PLA. Rats were randomly divided into blank control group(control group), heroin-dependent group (heroin group), and naloxone detoxification group(naloxone group) with 10rats each.METHODS: Morphine was subcutaneously injected into the rat with dose-increasing method to establish heroin-dependence rat model. Rats of naloxone group received subcutaneously injection of 2 mg/kg of naloxone to excite abstinent symptoms. The same dose of normal saline (NS) was injected in rats of control group. Model rats of each group were observed biologically and behaviorally. BDNF expression at different brain zone of rats in three different groups was tested with immunohistochemistry and digoxin-labeled oligonucleoide probe in situ hybridization technique.Comparison of the evaluation of abstinent symptoms in rats of each group.RESULTS: In the heroin group, the relative content of BDNF protein was higher in frontal lobe cortex, locus caeruleus and hippocampus than that of the control group( P ＜ 0.05); BDNFmRNA relative content was higher in frontal lobe cortex than that of the control group( P ＜ 0. 05) . In naloxone group, BDNF and its mRNA relative contents in frontal lobe cortex, locus caeruleus and hippocampus were higher than that of heroin group and control group ( P ＜ 0.05 ).CONCLUSION: Chronic administration of heroin could affect BDNF protein and its mRNA expressions in the corresponding brain areas of the rats, which suggests that the change of BDNF expression participates in heroin-dependence and detoxification.

Objective To evaluate the diagnostic value of Achilles tendon rupture by using X-ray plain films and MR images. Methods The plain films and MRI findings in 21 patients with operation proved acute Achilles tendon rupture were analyzed, and every manifestation on MR and operation were compared.Results The Achilles tendon rupture was diagnosed on MRI in all 21 cases. Complete rupture of Achilles tendon was showed in 7 and partial rupture in 14. MRI appearance of the rupture represented as thickening of Achilles tendon, hyperintensity in the tendon, and completely or partly discontinuance of the fibrous bundle. X-ray showed Achilles tendon rupture in 5, suspicious rupture in 12, and normal in 4. Operation showed Achilles tendon complete rupture in 9 and partial rupture in 12.Conclusion MRI can accurately show the degree and location of acute Achilles tendon rupture, which is very helpful for treatment. X-ray is the adminicular method in detecting Achilles tendon rupture and the diagnosis should be depended on MRI to confirm the the acute Achilles tendon rupture.

ObjectiveTo observe the therapeutic effects of calcium dobesilate combined with irbesartan in treating early diabetic nephropathy ( DN ).Methods65 patients with early DN were randomly divided into two groups,experiment group( irbesartan plus calcium dobesilate,n =34) and control group( irbesartan,n =31 ).After 24 week treatment,the urinary albumin excretion rate(UAER),fasting blood glucose ( FBG ),postprandial blood glucose (PBG) and glycosylated hemoglobin(HbA1c) were detected and compared between two groups before and after treat ment.ResultsUAER after treatment was significantly reduced in both 2 groups(t =8.074,12.89,all P＜0.01),and the decrement in the experiment group was more obvious than that in the control group with statistical significance ( t =3.965,P ＜ 0.05).ConclusionCalcium dobesilate combined with irbesartan has good effects in the treatment of early DN.

OBJECTIVE To explore the predictive value of human telomerase RNA gene component(hTERC) gene amplification and high-risk human papilomavirus(HR-HPV) testing in cervical intraepithelial neoplasia(CIN) as a marker for early diagnosis of cervix carcinoma.METHODS Fluorescence in situ hybridization(FISH) was used to detect the amplification of hTERC of cervical epithelial cells in 72 cases.By using hybrid capture 2(HC-2),two types of the HR-HPV DNA(HPV16/18) of each case were detected.Then,the results were compared with the pathologic diagnosis.The dual-color probe we used was GLP TERC/CSP 3.HeLa cells and lymphocytes from normal marrow were the positive control,while the cervical specimens from healthy outpatients were the negative control.RESULTS hTERC Gene amplification of specimens was tested in 72 cases,the positive amplification rate of hTERC gene in the cervicitis/CINⅠgroup and normal,compared to the cervical carcinomas(100%) and CIN Ⅱ/Ⅲ(68.75%),which showed a significant difference.The rates in CINⅡ and CINⅢ were 60.00% and 83.33%,respectively,which showed a significant difference compared with normal and CINⅠ/inflammation groups.hTERC gene amplification was positive in both HeLa cells and lymphocytes from normal marrow and HC-2 testing was positive in 32 cases of patients containing 11 cases of CINⅡ/Ⅲ,3 cases of cervical cancer,18 cases of cervicitis/CIN1 diagnosed.The positive predictive value(PPV) and specificity(Sp) of hTERC for the high-grade CIN was significantly higher than the PPV and Sp of HC-2 HR-HPV testing.CONCLUSIONS hTERC Gene involves in the progression and occurrence of cervical intraepithelial neoplasia and cervical squamous carcinoma.As a marker for early diagnosis of cervical intraepithelial neoplasia and cervical squamous carcinoma,the FISH method for hTERC gene is more reliable to differentiate the malignant diseases from the benign ones in cervixes than HC-2 HR-HPV DNA testing.The combined detection of HR-HPV and hTERC gene will provide more effective and suitable management to enhance the early diagnosis rate of cervical intraepithelial neoplasia and cervical squamous carcinoma.

Objective To investigate the effect of channel density on the gating properties of Anoctamin 1(Ano1,TMEM16A)Ca2+?activated chlo?ride channel. Methods Ano1 expression plasmids were transiently transfected into HEK293 cells. High density and low density of Ano1 was ob?tained after expressing the protein for 24 h and 6 h,respectively. Electrophysiological recordings were performed in the whole?cell patch clamp con?figuration. The activation kinetics of current traces was fitted by exponentials. Results The current density was significantly higher in cells express?ing Ano1 for 24 h than those expressing Ano1 for 6 h(P<0.05). The activation of Ano1 current in cells with low density was well fit by a single expo?nential withτslow of 292.71±38.11 ms. The activation of Ano1 current in cells with high density was well fit by two exponentials withτfast of 47.78±4.58 ms andτslow of 385.74±71.44 ms. ANO1 current in cells with high density has a rapid active component(τfast)more than low density. There was no significantly different of theτslow between cells with high density and low density of Ano1(P>0.05). Conclusion Our findings suggested that chan?nel density regulates the gating of Ano1. High channel density promotes activation of Ano1.
