Objective To investigate the anti-fibrogenesis property of imatinib mesylate in a rat model of liver fibrosis induced by carbon tetrachloride/olive oil and its effect on the expression of trans- forming growth factor(TGF)-?1.Methods Rat liver fibrosis was induced by intraperitoneal administra- tion of carbon tetrachloride and olive oil mixture twice a week for eight weeks.Imatinib mesylate was given 20 mg/kg daily by oral lavage.The control rats received saline by oral iavage.Liver collagen depo- sition was evaluated by immunohistochemistry with Masson staining.The activation of hepatic stellate cells was detemined by the immunohistoehemistry staining of?-smooth muscle actin.The mRNA expres- sions of TGF-?1,c-Abl and TIMP-1 were measured by RT-PCR.While protein expressions of TGF-?1, phosphorylated platelet-derived growth factor receptor and c-Abl were detected by Western blot and im- munohistochemical staining.Hepatic hydroxyproline content was also quantified.Results The collagen deposition[(16.23?1.01)%vs(25.61?0.92)%]and the number of activated HSCs(10.52?1.33vs 13.10?1.21)were reduced in the imatinib mesylate treatment group compared with the control group by 35% and 20%,respectively(P

Objective To investigate the feasibility and results of the application of both expanded cutaneous flap and temporoparietal fascia flap in total ear reconstruction with Medpor framework.Methods The main procedures consisted of three stages:stage Ⅰ-skin expansion,stage Ⅱ auricle formation that consisted of orientation of Medpor implant and creation of coverage for the implant by both expaned skin flap and temporoparietal fascia flap,and stage Ⅲ-treatment of residual ear and recontruction of auricular lobule. Results Twenty-two ears in 22 unilateral microtia patients were constructed using Medpor implants covered with both expanded cutaneous flap and temporoparietal fascia flap over the last three years,and they were accepted as pleasing by the patients.Conclusions Application of both expanded cutaneous flap and temporoparietal fascia flap can assure no extrusion of Medpor implant in ear reconstruction.Further more,the two layers of transferred tissues will not affect the profile details of the reconstructed ear.And because the skin covering the framework and fascia is derived from frommastoid region,the appearance and profile of the reconstructed auricle is true to nature and close to that of the opposite one.

Objective:To investigate the behavior of tobacco use among migrants in construction sites and explore the associated factors .Methods: A total of 652 migrants in 10 construction sites were selected in Xi’ an and Tongchuan .Chi-square and logistic regression were used to analyze the influencing factors of tobacco use.Results:The average age of the migrants in the construction site was (38.23 ± 10.61), and males occupied 82.7%(535/647) of the total.The current smoking rate of the migrants was 55.8%(364/652), with 64.3%(344/535) in males and 14.3%(16/112) in females.82.5%(329/399) smokers wanted to quit smoke , however only 52.7%(210/399) had tried quitting smoking in action, and 8.8%(35/399) quitted smoking successfully .Multivariable regression indicated that the migrants who were at lower age , and sick within 2 weeks, had perceived not difficult to stop smoking and who disagree with the benefits of smoking were more likely to try to quit smoking .Conclusion:Migrants in construction sites show their characteristics of old age , low level of health literacy , male-domination , high smoking rate and high intention of quitting smoking .Tobacco control projects should be implemented in construction sites to promote the translation of smoking quitting intention into action .

OBJECTIVETo investigate the characteristics, diagnosis, and treatment of ovotesticular disorder of sex development (OT-DSD).

METHODSWe retrospectively analyzed 2 cases of OT-DSD treated in our hospital. The patients were 19 and 15 years old, respectively, and both received systematic physical examination and examinations of the karyotype, sex hormone, adrenocorticotropic hormone (ACTH), color Doppler ultrasonography, urethrocystoscopy, and human chorionic gonadotropin (HCG) test. Under the laparoscope, we performed surgical gonad exploration, gonadectomy, and vulvar orthopedics. Intraoperative exploration and pathology confirmed true hermaphroditism in both cases, with sex selection as female. One underwent laparoscopic resection of the ovotestis, and the other removal of the testis with the ovarian tissue reserved.

RESULTSThe patients were followed up for 12 months postoperatively, which found no abnormality in either the vulvas or the genital glands.

CONCLUSIONSurgical exploration of the gonad is the only method for the diagnosis of OT-DSD and sex selection is the key to treatment. Laparoscopic surgical exploration of the gonad and vulvar orthopedics are the first treatment options.

·AIM: To improve our understanding of retinoschisis at the macular area.·METHODS: From January 2003 to January 2005, the patients whose macular retinoschisis was confirmed by optical coherence tomography (OCT) were included in the study. Their data and other results were further analyzed.·RESULTS: During that period, macular retinoschisis was found in 116 eyes which fit the including criteria. Among these, 94 eyes were pathological myopia; 17 were X-linked congenital retinoschisis; and 5 had excavation of optic disk.By analyzing the OCT figures, it was found that retinoschisis could happen at many locations within retinal neural epithelium, including inner, middle and outer part. The retinoschisis caused by different reasons differs in OCT results.·CONCLUSION: Retinoschisis at the macular area was not rare at the clinic, and the retinoschisis may be located at different parts of the retina. OCT was useful in the diagnosis and follow-up of macular retinoschisis.

OBJECTIVETo explore the therapeutic effect of qi benefiting blood activating method (QB-BAM) on acute exacerbation of chronic obstructive pulmonary disease (AECOPD) patients with blood stasis syndrome (BSS) by observing its effect on plasma fibrinogen (Fg) and D-dimer (D-D) levels.

METHODSSixty AECOPD patients with BSS were randomly assigned to the treated group and the control group, 30 in each group. All patients received conventional therapy for AECOPD. Those in the treated group were additionally injected with Shengmai Injection and Tanshinone IIA Injection. Clinical efficacy and indices including levels of Fg, D-D, PaO2, and PaCO2 were measured and compared before and after treatment.

RESULTSThe effective rate was 93.3% (28/30 cases) in the treated group, higher than that of the control group [73.3% (22/30 cases) , P < 0.05]. There was no significant difference in all indices between the treated group and the control group before treatment (P >0.05). After treatment all indices were significantly improved in the two groups (P < 0.01). But in the treated group levels of Fg and D-D decreased more and levels of PaO2 increased more (P < 0.01). Plasma levels of Fg and D-D levels were negatively correlated with PaO2 (r = -0.493, r = -0.438, P < 0.01) before treatment, and also negatively correlated with PaO2 (r = -0.452, r = -0.325, P < 0.01, P < 0.05) after treatment, but they were not significantly correlated with PaCO2 before and after treatment (P >0.05).

CONCLUSIONSQBBAM could play a therapeutic role in improving prethrombotic states of AECOPD patients with BSS. Plasma levels of Fg and D-D were related to the severity of AECOPD.

The contents of adenosine, gastrodin, 4-hydroxybenzyl alcohol, 4-hydroxybenzaldehyde, parishin and sulfur dioxide residue were compared in differently-processed Gastrodiae Rhizoma to provide the basis for a reasonable processing method of Gastrodiae Rhizoma. The analysis was performed on a Merck Purospher STAR column (4.6 mm x 250 mm, 5 μm) with a mobile phase consisting of methanol and water (containing 0.1% formic acid) under gradient elution at a flow rate of 1.0 mL x min(-1). The eluates were detected at 270 nm, and the column temperature was 35°C. The content of adenosin, gastrodin, 4-hydroxybenzyl alcohol, 4-hydroxy-benzaldehyde and parishin in processing of boiling or sulfur-fumigated were lower than that of in processing of steaming. Furthermore, the sulfur dioxide residue of sulphur-fumigated groups exceed 400 mg x kg(-1). This stable and reliable method will contribute to the quality control of different processed Gastrodiae Rhizoma.
