Observations on the Efficacy of Multi-functional Fire Needling plus Auricular Plaster Therapy for Moderate to Severe Acne Vulgaris / 上海针灸杂志

Objective To investigate the clinical efficacy of multi-functional fire needling plus auricular plaster therapy for moderate to severe acne vulgaris.Methods One hundred and fifty patients with moderate to severe acne vulgaris were randomly allocated to treatment and control groups, 75 cases each. Both groups were first given bloodletting at Ear apex and Helix 4. Then the treatment group received multi-functional fire needling plus auricular plaster therapy and the control group, auricular plaster therapy alone. The symptom and sign score was recorded in the two groups before and after treatment. The clinical therapeutic effects were compared between the two groups.Results There was a statistically significant pre-/post-treatment difference in the symptom and sign score in the two groups (P<0.01). There was a statistically significant post-treatment difference in the symptom and sign score between the two groups (P<0.05). The total efficacy rate and the cure and marked efficacy rate were 98.6% and 88.7%, respectively, in the treatment group and 93.2% and 60.8%, respectively, in the control group. There was a statistically significant difference in the cure and marked efficacy rate between the two groups (P<0.05).Conclusion Multi-functional fire needling plus auricular plaster therapy is an effective way to treat moderate to severe acne vulgaris.

Correlation of left ventricular hypertrophy detected by electrocardiogram and main cardiovascular accidents in hypertension patients / 重庆医学

Objective To analyze the predicting value of Cornell-QRS standard and Sokolow-Lyon voltage to left ventricular hypertrophy in hypertensive patients.Methods One hundred and seventy-four patients with primary hypertension were enrolled, who were divided into left ventricular hypertrophy group (LVH group,n=50)and non-LVH group(n=124).The blood pressure, Cornell-QRS standard and Sokolow-Lyon voltage were collected and compared in the following-up period.Results Compared with non-LVH group,in LVH group the history of hypertrophy was longer(P <0.05),percent of grade 3 hypertrophy was higher(P <0.05),and 24 h SBP was higher(P <0.05).During the following-up of 6 months,1 year,2 year,the SBP (systolic blood pressure), DBP (diastolic blood pressure),Cornell-QRS standard and Sokolow-Lyon voltage in LVH patients were all significantly decreased (P <0.01).Compared with non-LVH group,the incidence of non-fatal myocardial infarction and stroke was higher in LVH group[ 3(6.0%)vs .1(0.8%),P <0.05;6 (12.0%)vs .2 (1.6%),P <0.01 ].By Cox analysis,Cornell-QRS standard and Sokolow-Lyon voltage were respectively independent predictors to non-fatal myocardial infarction and also stroke.Conclusion Cornell-QRS stand-ard and Sokolow-Lyon voltage may be independent predictors to main cardiovascular accident in hypertensive patients.

Plasma free fatty acids composition and its association with nonalcoholic fatty liver disease / 重庆医学

Objective To study the relationship between plasma free fatty acids composition and the incidence of nonalcoholic fatty liver disease(NAFLD) .Methods By the design of case‐control study ,105 patients with NAFLD as cases and 110 healthy peo‐ple as controls were enrolled into the study .Plasma free fatty acid levels were determined by gas chromatography .Results High level of plasma palmitic acid(C16 :0)(OR=1 .769) was the risk factors of NAFLD ,while plasma levels of linoleic acid(C18 :2 n‐6) (OR=0 .855) and arachidonic acid(C20 :4 n‐6)(OR=0 .181)were negatively associated with the incidence of NAFLD .Conclusion These findings suggest that a proper ratio of diet fatty acids intake may reduce the risk of NAFLD .

Expression and significance of SM22α and α-SMA in varicose veins / 中华普通外科杂志

ObjectiveTo explore the relationship between the expression of smooth muscle 22 alpha ( SM22α),α-smooth muscle actin (α-SMA) and the development of varicose veins of the lower extremities. MethodsWe collected tissues of varicose saphenous vein in the experimental group,and what left over of normal saphenous vein tissues harvested for a coronary bypass operation ( control group).RT-PCR were applied to investigate the expression level of SM22αmRNA and immunohistochemical techniques were applied to investigate the expression level of SM22α and α-SMA protein in normal and varicose veins.ResultsThe expression level of SM22α mRNA in normal and abnormal veins was 0.2614 ±0.1168 and 0.5114 ± 0.1554 respectively ( t =5.020,P ＜ 0.01 ).The immunohistochemical staining showed that signals of SM22α and α-SMA protein existed in the cytoplasm of smooth muscle cells.The integrate optical density (IOD) of SM22α in normal and abnormal veins was 10 055 ± 3584 and 16 226 ± 3378 respectively ( t =4.991,P ＜ 0.01 ).The IOD of α-SMA in normal and abnormal veins was 9746 ± 3903 and 15 371 ± 4318 respectively (t =3.861,P ＜ 0.05 ). ConclusionsSM22α and α-SMA was down-regulated in varicose veins,indicating that the VSMC had transformed the typical contractile phenotype into the typical synthetic phenotype.Phenotype changes of VSMC further promote venous wall remodeling leading to the occurrence of varicose veins.
