OBJECTIVE:To discuss the application of pharmacoeconomics in "Treating Preventable Diseases" in traditional Chinese medicine. METHODS:Based on the brief introduction of pharmacoeconomics and the theory of "Treating Preventable Diseases",and taking preventing cerebral infarction by using drugs for invigorating blood circulation and eliminating stasis as example to analyze the feasibility and significance of pharmacoeconomics in the study of "Treating Preventable Diseases". RESULTS & CONCLUSIONS:The application of pharmacoeconomics in evaluating the theory of "Treating Preventable Diseases" will establish an objective evaluation system of Traditional Chinese Medicine and guide the rational use of drugs in clinic.

Objective To investigate the impact of experimental stress on serum glucose , insulin, glucagon, cortisol, and ep-inephrine in diabetic rats and its intervention with insulin and fluoxetine .Methods Type 2 diabetic rats model was induced by feeding with high sugar and high fat diet , and intraperitoneal injection of streptozotocin (STZ).The rats were divided into normal group , dia-betic control group , diabetic treated with insulin , and diabetic treated with fluoxetine .All the rats were exposed to multiple stressors (forced swimming, cold stimulation, rotation, restrain, and crowding) for 8 weeks.The rat blood sera collected from each group were analyzed with multiple parameters including glucose , insulin, glucagon, cortisol, and epinephrine at the 4th and 8th week.Results After experimental stress, the levels of glucose [(16.7 ±3.5)mmol/L vs (5.1 ±1.1)mmol/L, t =13.9, P <0.01], glucagon [(158.5 ±50.2)ng/L vs (120.8 ±38.7)ng/L, t =2.5, P <0.05], epinephrine [(203.8 ±48.6)pg/ml vs (158.7 ±42.6)pg/ml, t =2.9, P <0.01], cortisol [(21.3 ±4.8)ng/ml vs (18.2 ±3.8)ng/ml, t =2.1, P <0.05], and HOMA-IR (10.9 ±2.6 vs 3.3 ±0.8 , t =12.3 , P <0.01 ) of diabetic rats were significantly increased .The glucose level [ ( 9.7 ±2.1 ) mmol/L vs ( 16.7 ± 3.5)mmol/L, t =7.0, P <0.01] was significantly improved after treated with insulin .The levels of epinephrine [(158.8 ±37.5 ) pg/ml vs (203.8 ±48.6)pg/ml, t =3.0, P <0.01], and cortisol [(15.7 ±4.2)ng/ml vs (21.3 ±4.8)ng/ml, t =3.5, P <0.01 ] were significantly improved after treated with fluoxetine .Conclusions Experimental stress increased the levels of glucose , en-docrine hormone , and insulin resistance of diabetic rats .Treatment with insulin improved the glucose level and treatment of fluoxetine improved the endocrine hormone level .

Objective Uterine intravenous leiomyomatosiswas a rare type of uterus tumors.Because of the lack of knowledge about the ultrasonic patterns of this kind of disease,misdiagnosis frequently happens.Reviewing the cases and relevant researcheswas helpful to understand the disease and figure it out inultrasonic images.Methods Six cases of patients with uterine intravenous leiomyomatosis were reviewed which werehospitalized in Beijing Obstetrics and Gynecology Hospital during 2014 to 2016.All of the patients underwentultrasound examinations before surgery.The ultrasound findings,clinical presentations and pathological features of the 6 patients were evaluated.Results In 6 patients with uterine intravenous leiomyomatosis,3 cases were solid tumors,located in the cervix region and para uterine region,withirregular veinvascular inside;3 cases performance as multiple tumorlocated in dilated uterine vein,active tumor embolus were found in inferior vena cavain one of the 3 cases.Conclusions Uterine intravenous leiomyomatosisis found to be a solid mass located in the cervix region and para uterine region.The internal fissure of solid tumor is an important feature.Tumor extending to the iliac vein and inferior vena cava in some cases.Thusit is hard to be diagnosed before surgery by ultrasonography.Moreover,transvaginal ultrasound combined with inferior vena cava ultrasonography and echocardiography has a more obvious advantage in the diagnosis of the uterine intravenous leiomyomatosis.

Objective:To describe the epidemiological characteristics of mental disorders in community resi-dents aged 18 years and over in the Chifeng City of Inner Mongolia Autonomous Region.Methods:Six thousand three hundred and seventy six individuals aged 18 years and over were sampled using stratified Probability-Propor-tional-to-Size Sampling in Chifeng City in 2010.All respondents were investigated by face-to-face interview.The Composite International Diagnostic Interview-3.0 Computer Assisted Personal Interview (CIDI-3.0-CAPI)was used to make diagnoses based on the definition and criteria of the Diagnostic and Statistical Manual of Mental Dis-orders,Fourth Edition (DMS-IV).Results:A total of 4528 subjects completed the CIDI-3.0-CAPI.Regarding anxi-ety disorder,mood disorder,substance use disorder,and impulse control disorder,the 30-day adjusted prevalence rates (95%CI)were 2.5%(2.08% -2.99%,0.9%(0.67% -1.23%),0.5%(0.34% -0.76%),and 0.6%(0.41% -0.86%)respectively,and the 12 -month prevalence rates were 4.5% (3.93% -5.15%),2.4%(2.0% -2.90%),1.1% (0.84% -1.45%),and 1.0% (0.74% -1.32%)respectively.The lifetime adjusted prevalence rates were 6.6% (5.92% -7.36%),6.5% (5.81% -7.24%),2.7% (2.26% -3.21%),and 1.4%(1.23% -1.95%)respectively.Conclusion:According to morbidity,anxiety disorders,mood disorder,substance use disorders and impulse control disorders are common in Chifeng City of Inner Mongolia Autonomous Region se-quencely,being a prominent public health problem.

Methcathinone (MCAT) belongs to the designer drugs called synthetic cathinones, which are abused worldwide for recreational purposes. It has strong stimulant effects, including enhanced euphoria, sensation, alertness, and empathy. However, little is known about how MCAT modulates neuronal activity in vivo. Here, we evaluated the effect of MCAT on neuronal activity with a series of functional approaches. C-Fos immunostaining showed that MCAT increased the number of activated neurons by 6-fold, especially in sensory and motor cortices, striatum, and midbrain motor nuclei. In vivo single-unit recording and two-photon Ca²⁺ imaging revealed that a large proportion of neurons increased spiking activity upon MCAT administration. Notably, MCAT induced a strong de-correlation of population activity and increased trial-to-trial reliability, specifically during a natural movie stimulus. It improved the information-processing efficiency by enhancing the single-neuron coding capacity, suggesting a cortical network mechanism of the enhanced perception produced by psychoactive stimulants.
