Effect of laparoscopic salpingotomy with suturing on prognosis of patients / 中国综合临床

Objective To investigate the effect of laparoscopic salpingotomy with suturing on prognosis of patients.Methods One hundred and thirty two cases patients of laparoscopic salpingotomy and embryo extraction in our hospital from October 2015 to Febrary 2017 were were divided into observation group (68 cases) with suturing and control group (64 cases) without suturing according to the operation procedure.The patency of fallopian tube was observed at 3 months after operation and the intrauterine gestation rate and recurrent ectopic pregnancy rate were observed 1 years after operation in two groups.Results The fallopian tube patency in the observation group and the control group was 58 cases (85.3％) and 39 cases (60.9％) respectively at 3 months after operation.7 cases (10.3％) and 12 cases(18.8％) of the fallopian tube were not smooth in the observation group and the control group respectively at 3 months after operation.The fallopian tube obstruction in the observation group and the control group was 3 cases (4.4％) and 13 cases (20.3％) respectively at 3 months after operation.The patency rate of fallopian tube in the observation group was higher than that in the control group (Z =6.215,P ＜ 0.05).The intrauterine gestation rate (69.1％ (47/68)) in the observation group was significantly higher than that in the control group (37.5％(24/64)) 1 years after operation and the difference between the two groups was statistically significant (x2 =5.41,P ＜0.05).The rate of recurrent ectopic pregnancy in the observation group (10.3％(7/68)) was significantly lower than that in the control group (26.6％(17/64)) and the difference between the two groups was statistically significant (x2 =4.826,P ＜ 0.05).Conclusion The laparoscopic salpingotomy with suturing can improve the patency rate of the fallopian tube and the rate of intrauterine gestation and reduce the rate of recurrent ectopic pregnancy in the patients after the operation.

Clinical and pathological analysis of six cases of eruptive microvenular hemangioma / 中华皮肤科杂志

Objective To analyze the clinical and histopathologic features of eruptive microvenular hemangioma (EMVH). MethodsThe clinical and histological findings in six patients with EMVH were retrospectively reviewed.Results The patients were young or middle-aged,with a median age of onset of 34 years.The ratio of males to females was 1 ∶ 1.Clinically,all the patients experienced a sudden development of widespread,asymptomatic,brunneus,flat-topped papules and plaques measuring from 0.1 to 2.0 cm in diameter.Histopathologic examination revealed a poorly circumscribed proliferation of small,irregularly branched,thin-walled blood vessels haphazardly arranged between collagen fiber bundles in the dermis.The lumina of the blood vessels were often collapsed.There was no cellular atypia or mitosis.A variable degree of sclerosis was noted in the surrounding stroma.Immunobistochemical study revealed that the endothelial cells stained positive for CD34,CD31,and factor Ⅷ-related antigen.Conclusions The diagnosis of EMVH is proposed,and awareness of this disease may benefit its early diagnosis and avoidance of unnecessary treatment.

Wells syndrome: a clinical and histopathological review of seven cases / 中华皮肤科杂志

Objective To assess the clinical and histopathological features as well as treatment of Wells syndrome.Methods The clinical and pathological findings from 7 patients with Wells syndrome were retrospectively reviewed.Results Lesions were located on both lower extremities in 4 patients,on the back in 1 patient,on the face and trunk in 1 patient,and on the buttocks in 1 patient.Clinical manifestations included cellulitis (n =3),urticaria (n =1 ),annular plaques (n =1 ) and papulonodules (n =2).Histopathological examination of skin biopsies showed an infiltrate of numerous eosinophils with occasional flame figures in the dermis of all the patients.Leucocytoclastic vasculitis was found in 3 cases.No triggering factors were found in any of the 7 cases.The lesions nearly subsided in 3 patients after 2-week treatment with oral small-dosage prednisone and tripterygium glycosides.Conclusions Wells syndrome shows a wide diversity of clinical manifestations with distinct histological features.Systemic glucocorticoids and tripterygium glycosides are effective for the control of this condition.

The Corelation of Mucosal Involvement and Corticosteroid Dosage in Bullous Pemphigoid / 中华皮肤科杂志

Objective To study the corelation of mucosal involvement and corticosteroid dosage in the control of bullous pemphigoid(BP). Methods One hundred and three in-patients with bullous pemphigoid hospitalized during 1988 - 2002 were retrospectively analyzed for their mean corticosteroid dosage for controlling the disease and the duration for complete relieving the skin lesions, as well as the duration to start corticosteroid tapering. All the patients were divided into two groups: group A (37 cases) with mucosal involvement and group B (66 cases) without mucosal involvement. Results The mean corticosteroid dosage used to control the disease in group A was much higher than that in group B (t = 3.488, P 0.05). Conclusion Patients with mucosal involvement require a higher dosage of corticosteroids to control the disease.

Effects of Cryptotanshinone and Tanshinone ? on Proliferation, Lipid Synthesis and Expression of Androgen Receptor mRNA in Human Sebocytes in vitro / 中华皮肤科杂志

Objective To study the effects of tanshinone on the cultured immortalized human sebocytes and explore the mechanism of action of tanshinone in the treatment of acne. Methods MTT assay was applied to determine the effects of cryptotanshinone and tanshinone Ⅱ? at different concentrations on the proliferation of SZ95 sebocytes in 24 h, 48 h and 72 h after incubation. Lipid contents labeled with Nile red in SZ95 cells were analyzed by flow cytometry technique, and the expression of androgen receptor (AR) mRNA of SZ95 cells were detected by RT-PCR. Results Both cryptotanshinone and tanshinoneⅡ? inhibited the proliferation of SZ95 cells in a dose- and time-dependent mode, with the 50% inhibition concentration (IC50) of 7.473 ?mol/L (in 48 h) and 2.146?mol/L (in 72 h) for cryptotanshinone and 6.021 ?mol/L (in 48 h) and 2.25 ?mol/L (in 72 h) for tanshinone Ⅱ?. Additionally, as compared with the control group, the lipid content of SZ95 cells exposed to tanshinone Ⅱ? at 0.125?mol/L was decreased in 48h (P

Detection of M. leprae-specific Antigen with M-Dot-ELISA in Sera from Household Contacts of Leprosy Patients / 中华皮肤科杂志

We report the results of detecting M. lepraespecific antigen--phenolic glycolipid I (PGL--I) with modified M-Dot-ELISA in sera from 75 cases of household contacts (HC)of leprosy patients, which were all seropositive by Gelatin Particle Agglutination Test (MLPA)and ELISA. The results indicate that: (1 ) 16/75 (21. 3 % ) are antigen positive. The rates of positivity in HC of MB patients are much higher than those in HC of PB patients,the difference (P
