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.
RESUMO
Objective To investigate the effects of extracellular-signal regulated kinase (ERK) on hypoxic-ischemic brain damage of neonatal rats.Methods The hypoxic-ischemic brain damage model of neonatal Wistar rats was established as following:first the right common carotid artery of the rats was ligated;2 h after operation,the rats began to inhale 8%-oxygen oxygen-nitrogen gas mixture lasting for 2 h.Rats were randomly divided into three groups:sham-group,hypoxic-ischemic group and ERK inhibitor PD98059 group (the rats were injected PD98059 2 mg/kg 10 min before the ligation).Six hours after the models were done,hippocampi and cortex of the ligation side of rats in the three groups were collected,and the levels of malondialdehyde (MDA) and superoxide dismutase (SOD) were measured.Apoptosis of neuron was assessed by TUNEL staining.The expression of ERK1,ERK 2,Bcl-2 and Bax were examined by Western blot.The differences among the groups were analyzed with ANOVA and q test.Results Compared with the sham-group,the MDA level [(342.9± 10.8) μmol/L vs (181.5± 17.0) μmol/L,q= 6.35,P＜0.01) and the apoptosis rate of neuron [(18.80±1.37)% vs (3.53±0.34)%,q=6.06,P＜0.01) of hypoxic-ischemic group was higher,and SOD level was lower [(34.8±4.3) U/ml vs (63.4±4.3) U/ml,q=4.99,P＜0.01].While the apoptosis rate of neuron [(15.53±0.64) %] and MDA level [(252.0± 17.1) μmol/L] of PD98059 group were lower than those of hypoxic-ischemic group(q=3.87 and 5.28,P＜0.01respectively),the SOD level [(51.5 ± 3.8) U/ml] was higher than that of hypoxic-ischemic group (q=4.17,P＜0.01).There were no differences of ERK1 and ERK2 expressions among the three groups.The phosphorylated ERK1 and ERK2 levels of hypoxic-ischemic group were higher than those of sham-group (q=3.82 and 4.08,P＜0.01) and PD98059 group (q=4.79 and 5.12,P＜0.01).The expression of Bcl-2 and Bax of hypoxic-ischemic group were higher than those of sham-group (q=3.55 and 3.42,P＜0.01).Compared with hypoxic-ischemic group,Bcl-2 expression (q=3.71,P＜0.01) of PD98059 group was higher,and Bax expression (q=5.86,P ＜ 0.01) was lower.Conclusions ERK is involved in hypoxic-ischemic brain damage of neonatal rats through regulating the expression of apoptosis protein.
RESUMO
Objective: Nowadays, the power calibration methods of the microwave hyperthermia apparatus doesn't take the power loss of the radiator into account Aiming at this problem, the authors designed an equipment of measuring the actual output power of the microwave hyperthermia apparatus. A new method is proposed for calibration the output microwave power of microwave hyperthermia apparatus. Methods: The magnetron anode current was maintained at a default value by a control system. The microwave power generated by microwave source is coupled firstly to a low-power meter by the coaxial cable to measuring the power going through coaxial cable (P_(coaxial cable)). Then the microwave radiator is connected to the coaxial cable to make the microwave radiated by radiator. The radiator is assembled in the experimental device for the microwave completely absorbed by the water. The absorbed microwave energy of the water is calculated by measuring the water temperature change. The energy loss of the experimental device is calculated using the cooling rate. The output power of the radiator is equal to the ratio of the sum of the two aforementioned energy and the time. And the efficiency of the radiator η_(radiator), is equal to P_(radiator)/P_(coaxial cable) Results: The relationship between the actual output power of the microwave hyperthermia apparatus and the mag- netron anode current is P_(radiator) = 2η_(radiator) I. The efficiency of the radiator is η_(radiator)= (34±1)%. Conclusion: From the experimental results, the current method for calibration output power of microwave hyperthermia apparatus is defective, it dose not consider the conversion efficiency of radiator. Using the calibration method introduced in this paper, wecan accurately deter- mine the actual output power of microwave hyperthermia Apparatus.

Objective To study the clinical effect and the range of indications of oxygen-ozone treatment for lumber disc herniation. Methods 6～15 ml of oxygen-ozone(35～45 ?g/ml) were injected percutaneously into lumbar disc.In case of multiple disc herniations,the proceduce could be taken with two discs for once. Results 323 patients with 433 discs were treated by oxygen-ozone injection procedure.Total effective rate was 77.7%. Conclusions The treatment of lumber disc herniation by oxygen-ozone injection is simple,safe and effective with mild trauma.Oxygen-ozone not only can oxidize the proteoglycan in the nucleus leading to the contraction of nucleus,but also provide anti-inflammation effect with pain relief and without complication yet.
