Objective To explore relativity between serum cortisol and post-stroke depression in old patients with stroke. Methods Serum cortisols of 41 stroke patients were examined two weeks after stroke, and they were all assessed through Hamilton Depression Scale and then happening rates of post-stroke depression observed in both normal cortisol group and enhanced cortisol group were tested through χ2 test. Meanwhile relativity between serum cortisol level and post-stroke depression were analysised. Results Happening rates of post-stroke depression had an evidently difference between both normal cortisol group and enhanced cortisol group(χ2=4.11;P <0.05). Mark of normal cortisol group was 15.29±7.28, enhanced cortisol group was 25.85±10.81, both groups had an evidently difference( P <0.01). Serum cortisols were not obviously relative to depression degree in normal cortisol group( r =0.295;P =0.194) while they were obviously relative in enhanced cortisol group( r =0.702;P =0.001). Conclusion Enhanced cortisol could forecast higher possibility of depression after the old post-stroke, and detecting cortisol could offer theory foundation for prevention and cure of post-stroke depression.

Objective To investigate the clinical significance of YMDD mutation during Lamivudine therapy on chronic hepatitis B.Methods Fluorometric analysis PCR, ELISA were used to estimate the YMDD mutation, HBVDNA quantative level and HBeAg for HBV of 72 cases with chronic hepatitis B before therapy (0 month), and after Lamivudine therapy for 9,12,18 months.Results The YMDD mutation was not observed in these cases before Lamivudine therapy. The mutation was found in 8 cases (11.1%), 17 cases (23.6%) and 28 cases (38.9%) at 9, 12, 18 month for therapy. The YMDD mutation rate rose with the therapy time lasting (P＜0.05). Moreover, the YmDD mutation rate in the patients with HBVDNA quantity higher than 108 copies/ml was significantly higher than that in the patients with HBVDNA quantity lower than 108 copies/ml (P＜0.005). The YMDD variation rate in patients with HBeAg positive and in patients with HBeAg negative showed no significant difference (P＞0.05). The HBeAg negative conversion rate was significantly higher in non-mutation group than that in mutation group (P＜0.05).Conclusion The serum virus quantity may be regard as an early estimate indication of the development of YMDD mutation during Lamivudine therapy.

Objective To investigate the differences in clinical symptoms and risk factors between non-elderly and elderly patients with acute pulmonary thromboembolism(PTE).Methods Totally141 patients with acute PTE and 100 sex and age-matched healthy controls were enrolled in the study.The final diagnosis was confirmed by CT pulmonary angiography (CTPA) and/or pulmonary angiography and/or pulmonary perfusion imaging as well as medical history.The patients with acute PTE were divided into two groups according age:elderly group (n=78,age≥60 years),young group (n =63,age ＜ 60 years).Multivariate Logistic regression analysis was performed to identify independent risk factors of PTE and to confirm the risk of each factor.Results The morbidity rate of dyspnea,cough,chest distress and chest pain were 88.5％ (69 cases),76.9％ (60 cases),56.4％ (44 cases),15.4％ (12 cases) in elderly group,which was similar to 84.1％ (53 cases),69.8％ (44 cases),63.5％ (40 cases),25.4％ (16 cases) in young group (all P＞0.05)； while the morbidity rate of hemoptysis in elderly group [9.0％ (7 cases)] was lower than in young group [23.8％(15 cases)](P＜0.05).9％ (7 cases) in elderly patients without any symptoms were more than 1.6％ (1 cases) in young patients,but no significant differene (P＞0.05).There were more risk factors in the elderly group accompanying with diabetes (x2 =7.41,P ＜ 0.01),hypertension (x2 =14.51,P＜ 0.01),chronic obstructive pulmonary diseases (COPD) (x2 =7.42,P＜0.01) and previous stroke (x2 =4.91,P＜0.05)compared with young group.Independent risk factors for elderly acute PTE included COPD (OR:3.29,95％CI:1.04-10.46),previous deep veneus thrombosis(DVT) (OR:4.72,95％CI:1.68-13.27),cancers (OR:4.35,95％CI:1.00-18.13) and previous stroke (OR:5.13,95％CI:1.15-24.52).Independent risk factors for non-elderly PTE included previous DVT (OR:11.94,95％ CI:3.35-42.60)and cancers (OR:11.44,95％CI:1.44-89.92).Conclusions Much attention should be paid to the identification of diagnosis of acute PTE depending on the non-specific clinical features,although dyspnea may be the most frequency symptoms,but unexplained cough and chest distress should be alert for PTE.COPD,cancer,DVT and previous stroke are independent and important risk factors for elderly acute PTE.

AIM: To prepare ethosomes and study on transdermal resorption of tanshinone ethosomes in vitro. METHODS: Tanshinone ethosomes were prepared by thin-film ultrasonic method.The different dosage regimens and volume on the transdermal resorption of tanshinone were evaluated through excised mice skin in vitro using modified Franz-diffustion cells. RESULTS: The mean particle diameter of ethosomes was 79.7 nm,and the encapsulation efficiency was about 81.2%.Cumulative penetration amount of tanshinone from ethosomes was 1024? 104.0 ng/cm2 and skin residual amount was 345.2?58.0 ng/cm2.Cumulative penetration amount increased with ethosomes volume.Liposomes failed to promote the penetration of tanshinone,and its skin residual amount was 625.3 ?124.5 ng/cm2,water-ethanolic suspension also could not promote the penetration of tanshinone,and skin residual amount was 765.0?60.00 ng/cm2. CONCLUSION:Ethosomes can improve significantly the transdermal delivery of tanshinone.

Objective To investigate the protection of Liuwei Dihuang Jiawei Capsula(LDJ Capsula,Rehmanniae Capsula of Six Ingredients) on diabetic nephropathy(DN) rats′ kidney and effect on renal protein kinase C(PKC) activity and connective tissue growth factor(CTGF) of DN rats.Methods The DN rat models were induced by ip injection of streptozotocin(STZ).The rats were randomly divided into five groups: control group; DN model group;Lotensin group;LDJ Capsula group;and Lotensis and LDJ Capsula combination group.Drug intervention term was 12 weeks.Renal ultrastructure was observed by transmission electron microscope and Masson staining.Relative kidney weight,blood glucose level,serum and urine creatinine content,creatinine clearance,excretion rate of the 24 hour urine protein,renal PKC activity,and CTGF expression in renal cortex were measured by immunohistochemistry.Results Deposition of collagen in renal of DN rats was conspicuous.Relative kidney weight,blood glucose level,serum and urine creatinine content,creatinine clearance,excretion rate of 24 h urine protein,renal PKC activity and CTGF expression of DN rats increased obviously.All Lotensin,LDJ Capsula,and the combination of these two drugs could decrease renal PKC activity and CTGF expression and ameliorate proteinuria and renal function of DN rats.At the same time they all could abate the deposition of collagen in renal of DN rats.Combination of these two drugs could decrease renal PKC activity and CTGF expression more ob-viously and at the same time had more notable protective effect on kidney of DN rats.Conclusion All Lotensin,LDJ Capsula,and the combination of these two drugs could protect kidney of DN rats.The combination of these two drugs has more obviously protective effect than using Lotensin only.

Objective To investigate the expression of nuclear factor kappaB(NF-κB) and regulated upon activation normal T cell expressed and secreted chemokine(RANTES) during the formatiom of ascending aortic aneurysm. Methods Forty Wistar rats were randomly divided into the control group(n=20) and the experimental group(n=20).The rat models were made by ligating the ascending aorta. The ascending aortas were taken after ligation for 3months. Immunohistochemistry staining was performed to detect the protein expression of NF-κB and RANTES. The expression of NF-κB and RANTES mRNA were detected by RT-PCR. Results Immunohistochemisry staining results showed NF-κB and RANTES expression significantly increased in aneurysm, while there was a little positive staining in the control group. RT-PCR results indicated that the expression levels of NF-κB and RANTES in the aneurysm were stonger than that of the control group. The expression of NF-κB and RANTES mRNA were remarkably correlated. Conclusion The expression of NF-κB and RANTES in ascendin aortic aneurysm are stronger than that in the control. NF-κB and RANTES may contribute to the pathogenesis of the ascending aortic aneurysm.

Objective To explore the effects of batroxobin on the microcirculation of patients with severe acute pancreatitis (SAP). Methods A total of 38 patients with SAP were randomly divided into group A (21 cases) and group B (17 cases). Patients in group A were treated with routine method andpatients in greup B were treated with routine method plus batroxobin injection. Another 18 normal individuals were used as control. The levels of plasma endothelin (ET), thromboxane B_2 (TXB_2) and 6-keto-PGF_(1α)were measured by radioimmunoassay. At the same time, the ratio of TXB_2/6-keto-PGF_(1α) was observed. The Balthazar CT and APACHE Ⅱ scores were monitored and compared between group A and group B. Results The levels of plasma 6-keto-PGF_(1α) were significantly higher while the levels of plasma ET, TXB_2 and the ratio of TXB_2/6-keto-PGF_(1α) were significantly lower in group B at 6 days after admission [(129.3 ± 12.9) ng/L, (93.8 ± 9.9) ng/L, (254.4 ± 24.9) ng/L and 1.83 ± 0.31]as compared with those in group B on admission [(98.9 ± 10.7) ng/L, (140.3 ± 13.1) ng/L, (311.4 ± 31.5) ng/L and 3.16 ± 0.54]and group A at 6 days after admission [(108.2 ± 11.6) ng/L, (120.3 ± 11.4) ng/L, (308.5 ± 31.1) ng/L and 2.84 ± 0.43](P < 0.05). The Balthazar CT and APACHE Ⅱ scores in group B at 6 days after admission were significantly lower than those in group B on admission and group A at 6 days after admission (P< 0.05 or < 0.01). Conclusion Batroxobin is an effective way to improve the microcirculation in SAP.

Objective To investigate the clinical and histological characteristics of trichilemmal carcinoma (TLC). Methods A clinicopathological analysis of 13 cases of TLC was carried out. Results There were 9 males and 4 females among the 13 patients with TLC who were aged from 34 to 87 years (mean: 70 years). Clinically, the tumor presented as an exophytic mass; histologically, it was characterized by the proliferation of epithelial cells and keratinization of outer root sheath. Cytologically atypical clear cells predominated in the tumor tissue. Microscopy revealed different growth patterns of tumor cells, which included solid growth pattern, tobular pattern and trabecular pattern. Periodic acid Schiff (PAS) stain demonstrated clear cells in all the tumor tissues from the 13 patients. Immunohistochemistry was performed in tissue samples from 6 patients, and showed that these samples were positive to high molecular weight cytokeratin (CK-HMW) and epithelial membrane antigen (EMA), but negative to carcinomebrynic antigen (CEA), S-100, cytokeratin 8 (CK8)and epithelial antigen(Ber-Ep4). Follow-up over 4 months to 5 years revealed neither recurrence nor metastasis in 9 cases.Conclusions TLC is a low-grade malignancy of skin adnexal tumor without distinctive clinical features, and should be differentiated from other malignant clear cell tumors of the skin.
