Objective: To observe the clinical efficacy of combined needle-embedding and SSRIs for depressive sleep disorder. Method: Upon admission, 71 depression cases were randomized into needle-embedding group of 24 cases, using combined needle-embedding and SSRIs, acupuncture group of 21 cases, using combined acupuncture and SSRIs, and medication group of 26 cases, using SSRIs alone. After 1, 2, 4 and 6 weeks of treatment, the HAMD sleep scores were compared. Result: The HAMD sleep scores in the needle-embedding and acupuncture group were remarkably superior to the medication group and there was significant statistical difference after 1, 2 and 4 weeks of treatment (P<0.01). However, there was no statistical difference after 6 weeks of treatment. Conclusion: SSRIs can improve HAMD sleep scores. The combined needle-embedding or acupuncture with SSRIs can work faster and better than medication alone. There was no statistical difference between needle-embedding and acupuncture group, however, needle-embedding can reduce the treatment frequencies and therefore has more active clinical meaning.

Objective To explore the effect of mefformin on glucose metabolism of rat myoblast with high fat environment.Methods The skeletal muscles of suckling Wister rats were subjected to primary culture.The myoblasts of passage 5 were divided into 5 groups:The control group was cultured in DMEM with 0.5％ BSA for 12 h.The high-fat group was exposed to 0.3 mmol/L palmitic acid for 12 h.On the basis of high-fat treatment,three intervention groups were added with 2.5,5.0 and 7.5 μg/ml metformin,respectively,for additional 24 h.Isotope tracer method was conducted to show the influence on 2-dexoy-D-[3H]glucose uptake of rat myoblast.Results With the increasing concentration of mefformin,[3H]-G uptake elevated [ ( 1.83 ± 0.34) 10-2pmd/( min · g) vs (2.33 ± 0.47 ) 10-2 pmd/( min · g),P ＜ 0.05 ],and the group of 7.5 μg/ml metformin uptakes the most.Conclusions Metformin can upregulate the glucose-uptake in rat myoblasts under the environment of high fat,and it shows a dose-dependent relationship.

Objective To investigate the relationship between the onset of lower extremity venous thrombotic disease and seasons.Methods A retrospective study was conducted, 300 patients with lower extremity venous thrombotic disease admitted to HandanCity Hospital of Traditional Chinese Medicine (TCM) from August 2012 to February 2014 were enrolled, the incidences and TCM syndromes of patients with lower extremity venous thrombotic disease in different seasons were observed, and the pathogenesis and relationships between the types of TCM syndrome and seasons were analyzed.Results There were 142 patients with lower extremity superficial thrombophlebitis, and 158 cases with lower extremity deep venous thrombosis, the incidence of lower extremity venous thrombotic disease in spring was significantly higher than that in summer and autumn [32.8% (86/262) vs. 21.3% (54/254), 18.4% (50/272), bothP < 0.01], but lower than that in winter [32.8% (86/262) vs. 37.2% (110/296)], the difference was not statistically significant (P > 0.01); while the incidence of lower extremity venous thrombotic disease in winter was significant higher than those in summer and autumn (allP < 0.01). The incidences of damp and heat downward flow type in autumn and summer were increased compared with those in winter and spring [55.6% (30/54), 60.0% (30/50) vs. 20.0% (22/110), 23.3% (20/86), allP < 0.01], while the incidences of lower extremity venous thrombotic disease with damp heat and stasis syndrome in winter and spring were increased compared with those in summer and autumn seasons [80.0% (88/110), 76.7% (66/86) vs. 44.4% (24/54), 40.0% (20/50)].Conclusions The incidence of lower extremity venous thrombotic disease is related to seasons, and the onset is high in winter and spring, damp heat and stasis syndrome being the main type; according to different seasons, clinical treatment can direct to different pathogenic factors to adopt different preventive measures interfering with the patient's constitution in order to eliminate or reduce the risk factors, achieving the effect of the disease prevention.

ObjectiveTo study the effect of Ghrelin on activation of UCP3 and phosphorylation of ACC under the high fat environment in rat myoblast,and to support the study on prevention of type 2 diabetes.MethodsThe rat myoblast were exposed to 0.3 mmol/L palmitic acid for 12 h,at the same time,10-11 mol/L,10-9 mol/L,10-7 mol/L Ghrelin were added.The expression of UCP3 mRNA was determined by RT-PCR.The protein levels of UCP3 and p-ACC were measured by western blotting.ResultsCompared with the control group,UCP3 mRNA and the protein levels of UCP3 and p-ACC were obviously decreased in 0.3 mmol/L PA group(UCP3 mRNA:P =0.000,UCP3 protein levels:P =0.000,p-ACC protein levels:P =0.003).Compared with the 0.3 mmol/L PA group,with the increasing concentration of Ghrelin,UCP3 mRNA and the protein levels of UCP3 and p-ACC were elevated.The effects of 10-7 mol/L Ghrelin were significant(UCP3 mRNA:P =0.017,UCP3 protein levels:P =0.000,p-ACC protein levels:P =0.007).ConclusionsGhrelin could enhance activation of UCP3 and phosphorylation of ACC under high fat environment in rat myoblast.

Objective To clarify the effectiveness of QS Nd ∶ YAG laser on melasma in Chinese patients.Methods A group (n=45) of patients previously diagnosed as facial melasma were treated with QS Nd ∶ YAG laser at approximately 1 week intervals.Eleven to twenty treatments were per formed for each patient.The treatment efficacy of QS Nd ∶ YAG laser was evaluated by patients and doctors,respectively,at various time point such as before treatment,5 weeks and 10 weeks after treatment and end of the treatment.The skin melanin index and the transepidermal water loss were e valuated by the skin multifunction tester at different time point,respectively.Results Compared with untreated,the melanin index of melasma areas decreased significantly after the laser treatment for 5 weeks,10 weeks and the end of treatment.But there was no significant difference in the melanin index of normal skin areas with or without laser treatment.Compared with untreated,the transpidermal water loss of melasma areas increased significantly after the laser treatment for 5 weeks,10 weeks and end of treatment.The patients' skin became smooth,delicate,pores shrink and more flexible.In 45 melasma patients treated by QS Nd ∶ YAG laser,8 cases basically cured (17.78 ％),25 cases were markedly effective (55.56 ％),12 cases improved (24.44 ％) and only 1 case was uneffective (2.22 ％).Theoverall effective rate was 73.33 ％.Conclnsions QSNd∶ YAG laser is a useful treatment modality for Chinese women who have melasma with precise efficacy,less side effects and high safety.
