Objective:To describe the current situation of mental health service utilization of community pa-tients with five mental disorders in Inner Mongolia Autonomous Region and provide reference for health education and formulating relevant policies.Methods:The multistage stratified sampling method with unequal probability was used to select a total of 12 315 community residents aged 18 and over in Inner Mongolia Autonomous Region.Using Composite International Diagnostic Interview,mood disorders,anxiety disorders,substance use disorders,intermit-tent explosive disorders,and eating disorders,and health service utilization were investigated.Descriptive statistics was completed by single factor analysis method.Results:The lifetime rates of consultation and treatment of any mental disorder were 18.7％and 10.2％,respectively.The highest proportion of patients received treatment by non-medical professionals was 31.4％,followed by psychiatrists in psychiatric hospital or psychologists in general hospitals.Among the patients,1.1％of them received medication,and 2.5％received psychotherapy.Conclusion:The utilization rate of mental health services in community patients with five mental disorders is relatively low.It is necessary to conduct health education for medical help seeking properly.

The amygdala is an important hub for regulating emotions and is involved in the pathophysiology of many mental diseases, such as depression and anxiety. Meanwhile, the endocannabinoid system plays a crucial role in regulating emotions and mainly functions through the cannabinoid type-1 receptor (CB₁R), which is strongly expressed in the amygdala of non-human primates (NHPs). However, it remains largely unknown how the CB₁Rs in the amygdala of NHPs regulate mental diseases. Here, we investigated the role of CB₁R by knocking down the cannabinoid receptor 1 (CNR1) gene encoding CB₁R in the amygdala of adult marmosets through regional delivery of AAV-SaCas9-gRNA. We found that CB₁R knockdown in the amygdala induced anxiety-like behaviors, including disrupted night sleep, agitated psychomotor activity in new environments, and reduced social desire. Moreover, marmosets with CB₁R-knockdown had up-regulated plasma cortisol levels. These results indicate that the knockdown of CB₁Rs in the amygdala induces anxiety-like behaviors in marmosets, and this may be the mechanism underlying the regulation of anxiety by CB₁Rs in the amygdala of NHPs.

Objective:To analyze the characteristics of the circular cases violating the " nine prohibitions" in recent years, so as to provide a basis for further strengthening the moral culture construction of the healthcare industry.Methods:Data came from the reported cases released on official websites of the discipline inspection committees, supervision committees and health committees at all levels in China from December 2013 to August 2021, which were identified by searching the keyword " case or report or moral culture and nine prohibitions" . Descriptive analysis and frequency analysis were conducted on the reported time, region and province, as well as the involved units, departments, persons, punishment results and case classification data of all the cases.Results:A total of 102 cases violating the " nine prohibitions" were included, of which the cases from 2014 to 2015 topped the rest, accounting for 51.96%(53 cases). Top three regions of these cases were central China, east China and southwest China, with 31 cases, 27 cases and 18 cases respectively. The units involved were mainly tertiary medical institutions, accounting for 44.12%(45 cases). More medical staff(134 people) than administrative staff(85 people) were involved in the cases. The largest number of cases was receiving kickbacks, with 52 cases(50.98%). The punishment results of cases included judicial procedures(76 people), Party discipline and government discipline punishment(67 people) and organizational punishment(76 people).Conclusions:Moral culture problem in China′s healthcare sector is characterized in wide coverage, complexity, comprehensiveness and long-term. Relevant authorities should keep up their efforts in enhancing the awareness of medical workers, improving the synergy mechanism in this regard, and strengthening the internal management of medical institutions.

Objective:To investigate the prognosis of severe hyperbilirubinemia in full-term infants who met the exchange transfusion criteria and were treated by blood exchange transfusion and phototherapy.Methods:A total of 168 full-term infants with severe hyperbilirubinemia who met the criteria for exchange transfusion and were hospitalized in the Neonatology Department of seven tertiary hospitals in Hebei Province from June 2017 to December 2018 were retrospectively included. According to the treatment protocol, they were divided into two groups: exchange transfusion group (38 cases) and phototherapy group (130 cases). Two independent sample t-test and Chi-square test were used to compare the clinical manifestations and follow-up results between the two groups. Multivariate logistic regression was used to analyze the risk factors for poor prognosis. Results:Neonatal severe hyperbilirubinemia in the exchange transfusion and phototherapy group were both mainly caused by hemolytic disease [42.1%(16/38) and 29.2%(38/130)], sepsis [28.9%(11/38) and 11.5%(15/130)] and early-onset breastfeeding jaundice [15.8%(6/38) and 11.5%(15/130)]. Total serum bilirubin level on admission in the exchange transfusion group was significantly higher than that in the phototherapy group [(531.7±141.3) vs (440.0±67.4) μmol/L, t=3.870, P<0.001]. Moreover, the percentage of patients with mild, moderate and severe acute bilirubin encephalopathy in the exchange transfusion group were higher than those in the phototherapy group [15.8%(6/38) vs 3.8%(5/130), 7.9%(3/38) vs 0.8%(1/130), 13.2%(5/38) vs 0.0%(0/130); χ2=29.119, P<0.001]. Among the 168 patients, 135 were followed up to 18-36 months of age and 12 showed poor prognosis (developmental retardation or hearing impairment) with four in the exchange transfusion group (12.9%, 4/31) and eight in the phototherapy group (7.7%, 8/104). Multivariate logistic regression analysis showed that for full-term infants with severe hyperbilirubinemia who met the exchange transfusion criteria, phototherapy alone without blood exchange transfusion as well as severe ABE were risk factors for poor prognosis ( OR=14.407, 95% CI: 1.101-88.528, P=0.042; OR=16.561, 95% CI: 4.042-67.850, P<0.001). Conclusions:Full-term infants who have severe hyperbilirubinemia and meet the exchange transfusion criteria should be actively treated with blood exchange transfusion, especially for those with severe ABE, so as to improve the prognosis.

Objective:To investigate the protective effect and mechanism of microRNA-210 agonist (agomiR-210) on kidney in diabetic kidney disease (DKD) rats.Methods:Thirty-six 5-week-old male SD rats were divided into normal control (NC) group, agomiR-NC control group, agomiR-210 control group, DKD model group, DKD+agomiR-NC group and DKD+agomiR-210 group, with 6 rats in each group. Diabetic rats were established by a high-fat diet combined with intraperitoneal injection of streptozotocin (STZ), then were fed for 12 consecutive weeks to construct DKD model rats. During 2nd-4th week of continuous feeding, the rats in DKD+agomiR-210 group were injected with 20 nmol/kg agomiR-210 via tail vein twice a week. Blood glucose levels, 24 h urine albumin (Alb) and 24 h urine microalbumin (MAU) contents were measured regularly. At the end of the 12th week, the rats were sacrificed, and renal tissues were collected. The renal histopathological changes were assessed by HE, PAS and Masson staining methods. The mRNA and protein expression levels of tumor necrosis factor-α (TNF-α), interleukin (IL)-1β and IL-6 in renal tissues were detected by RT-qPCR and Western blot. The distributions and expressions of α-smooth muscle actin (α-SMA), typeⅠ collagen (Col-Ⅰ), type Ⅳ collagen (Col-Ⅳ) and fibronectin (FN) in renal tissues were detected by immunohistochemical method. The protein expression levels of phospho(p)-Smad3 and p-NF-κB p65 in renal tissues were detected by Western blot and immunohistochemical methods.Results:Compared with DKD model group, the renal pathological damages in DKD+agomiR-210 group were improved, the blood glucose level, glycogen deposition and collagen accumulation were significantly decreased (all P<0.05), the urinary excretions of Alb and MAU were significantly reduced (all P<0.01), and the expressions of TNF-α, IL-1β, IL-6, α-SMA, Col-Ⅰ, Col-Ⅳ, FN, p-Smad3 and p-NF-κB p65 in renal tissues were significantly decreased (all P<0.01). Conclusion:AgomiR-210 can alleviate renal pathological changes and urinary Alb and MAU excretion in rats with DKD, which may be related to its inhibition of Smad3 and NF-κB activity.

Objective: To compare the efficacy and safety of active transfer of plaque (ATP) versus provisional stenting (PS) with drug-eluting stents (DES) for the treatment of coronary bifurcation lesions. Methods: A total of 1 136 patients with bifurcation lesions hospitalized in 6 selected hospitals between January 2010 and January 2014 were included in this prospective observational trial, patients were divided into either ATP (n=560) or PS group (n=576) accordingly. The primary endpoint was target lesion revascularization within 1 year, and the second endpoints were all-cause death, cardiogenic death, myocardial infarction, stent thrombosis, stroke, recurrent angina within 1 year. Results: There were no significant differences in age, sex, hypertension, diabetes, hyperlipidemia and smoking history between the two groups (P>0.05). The incidence of TIMI blood flow <3 grade in the side branch (1.6%(9/560) vs. 7.5% (43/576), P<0.01), acute occlusion of the side branch (1.3%(7/560) vs. 7.1%(41/576), P<0.01) and implanted stents of side branch (1.8%(10/560) vs. 7.8% (45/576), P<0.01) were significantly lower in the ATP group than those in the PS group. During the one year follow up, the rate of target lesion revascularization was similar between ATP group and PS group (4.6%(26/560) vs. 4.0%(23/576), P=0.66). Conclusions The effectiveness and safetyof ATP techniquein the patients with coronary bifurcation lesions is comparable to the PS technique. However, ATP technique is superior to PS technique on effectively reducing the incidence of implanted stents in the side branch.

Objective To investigate the inhibiting effect of CGP77675 (CGP),a Src inhibitor,on epithelial-mesenchymal transition (EMT) of human retinal pigment epithelial (RPE) cells induced by transformation growth factor-β1 (TGF-β1).Methods Human RPE cell line (ARPE19 cells) was cultured in vitro and divided into control group,TGF-β1 group and TGF-β1 +CGP group.Corresponding agent was added into culture medium based on grouping.The morphology of the cells were examined under the optical microscope 3 days after culture.The expressions of EMT-related genes and proteins in the cells were detected by real-time quantitative PCR and Western blot,respectively,including fibronectin 1 (FN 1),and plasminogen activation inhibitor 1 (PAI1),and the expressions of zonula occludens protein 1 (ZO1) and cytoskeleton protein filamentous actin (F-actin) were detected by immunofluorescence staining.MTT assay was employed to evaluate the cell proliferation rate.The migration distance of the cells was measured by scratch test.Results The ARPE19 cells in the control group showed an epithelial-like morphology and F-actin and ZO-1 were expressed along cell membrane.In the TGF-β1 group,the cells appeared to be fibrous-like,and the fluorescence staining of F-actin was disordered and ZO-1 was discontinuous on the cell membrane.The cells in the TGF-β1 +CGP group remained to be an epithelial-like in shape with clear and complete expressions of F-actin and ZO-1.The relative expressions of FN1 mRNA and PAI1 mRNA in the cells were 0.211 ± 0.080 and 0.116±0.073,1.000±0.001 and 1.000±0.001,0.368±0.097 and 0.362±0.048 in the control group,TGF-β1 group and TGF-β1 +CGP groups,showing significant differences among the groups (F=33.14,82.92;both at P＜0.01),with the highest expressions ofFN1 mRNA and PAI1 mRNA in the TGF-β1 group (all at P＜0.05).The relative expressions of FN1 and PAI1 proteins were 0.166±0.055 and 0.327±0.066,1.000±0.001 and 1.000± 0.001,0.143 ± 0.030 and 0.260 ± 0.077 in the control group,TGF-β1 group and TGF-β1 + CGP group,with significant differences among three groups (F=181.90,48.85;both at P＜0.01),and the expressions FN1 and PAI1 proteins were significantly higher in the TGF-β1 than those in the control group and TGF-β1 +CGP group (all at P＜0.05).The cell proliferative rate in the TGF-β1+CGP group was (79.30±3.44) ％ and (54.80±7.39) ％ at the third day and seventh day after culture,which were significantly reduced in comparison with (99.50 ± 1.00)％ and (99.10±0.50)％ in the control group as well as (95.10±4.20)％ and (92.10±4.50)％ in the TGF-β1 group (all at P＜0.05).The migration distance was disappeared in the TGF-β1 group,and the scratch width was not obviously changed in the TGF-β1 +CGP group.Conclusions Src inhibitor can inhibit EMT process of ARPE19 cells induced by TGF-β1,indicating that Src signaling pathway may play a critical role in EMT of RPE cells.

Critical ultrasonography(CUS) is different from the traditional diagnostic ultrasound,the examiner and interpreter of the image are critical care medicine physicians.The core content of CUS is to evaluate the pathophysiological changes of organs and systems and etiology changes.With the idea of critical care medicine as the soul,it can integrate the above information and clinical information,bedside real-time diagnosis and titration treatment,and evaluate the therapeutic effect so as to improve the outcome.CUS is a traditional technique which is applied as a new application method.The consensus of experts on critical ultrasonography in China released in 2016 put forward consensus suggestions on the concept,implementation and application of CUS.It should be further emphasized that the accurate and objective assessment and implementation of CUS requires the standardization of ultrasound image acquisition and the need to establish a CUS procedure.At the same time,the standardized training for CUS accepted by critical care medicine physicians requires the application of technical specifications,and the establishment of technical specifications is the basis for the quality control and continuous improvement of CUS.Chinese Critical Ultrasound Study Group and Critical Hemodynamic Therapy Collabration Group,based on the rich experience of clinical practice in critical care and research,combined with the essence of CUS,to learn the traditional ultrasonic essence,established the clinical application technical specifications of CUS,including in five parts:basic view and relevant indicators to obtain in CUS;basic norms for viscera organ assessment and special assessment;standardized processes and systematic inspection programs;examples of CUS applications;CUS training and the application of qualification certification.The establishment of applied technology standard is helpful for standardized training and clinical correct implementation.It is helpful for clinical evaluation and correct guidance treatment,and is also helpful for quality control and continuous improvement of CUS application.

Objective To evaluate the effects of inhalation sevoflurane in the early ischemia and reperfusion on pulmonary inflammatory response in patients undergoing cardiac surgery with extracorporeal circulation (ECC). Methods Forty patients with rheumatic heart disease scheduled for elective valve replacement were randomly assigned into 2 groups (20 patients in each group): control group and sevoflurane group. In sevoflurane group, 2% sevoflurane was inhaled for 15 min before and after the ascending aorta was blocked, and also before and after the ascending aorta was opened. Paitents in control group didn′t inhale sevoflurane. Time was defined as the followings: after anesthesia and before skin incision (T0), immediately before ECC (T1), immediately after ECC (T2), 2 h after ECC (T3), 6 h after ECC (T4) and 24 h after ECC (T5). At T0, T2, T3, T5, the radial artery blood was obtained to detect the levels of plasma tumor necrosis factor-α(TNF-α), interleukin-8(IL-8) and soluble intercellular adhesion molecule-1(sICAM-1). At T1, T2, the pulmonary artery and pulmonary vein blood was obtained to detect the neutrophil count and calculate the differences between the vein and artery. At T0, T2, T3, T4, T5, the arterial blood gas was detected and differences of alveoli-arterial oxygen pres [P(A- a)O2], oxygenation index (OI), static compliance (Cst) were calculated. Results The levels of plasma TNF-α, IL-8 and sICAM-1 were higher at T2, T3, T5 than those at T0 in two groups (P<0.05). The levels of plasma TNF-α, IL-8 and sICAM-1 were decreased in sevoflurane group at T2 and T3, compared with those in control group (P<0.05). The neutrophil counts of pulmonary artery, pulmonary vein and the differences between the vein and artery were higher at T2 than those at T0 in two groups (P<0.05). The neutrophil counts of pulmonary artery, pulmonary vein and the differences between the vein and artery were decreased in sevoflurane group at T2 compared with those of control group (P<0.05). The level of P(A- a)O2 was higher at T2, T3, T4 and T5 than that at T0 in two groups (P<0.05). The level of OI was decreased at T2, T3, T4 and T5 compared with that at T0 in two groups (P<0.05). The level of Cst was decreased at T2, T3 and T4 compared with that at T0 in two groups (P<0.05). The level of P(A-a)O2 was decreased in sevoflurane group at T2, T3 and T4 compared with that in control group (P<0.05). The levels of OI and Cst were higher in sevoflurane group at T2, T3 and T4 compared with those in control group (P<0.05). Conclusions Severe pulmonary inflammation often occurs during cardiac surgery with ECC, and it can be relieved by inhalation of sevoflurane in the early ischemia and reperfusion.

Objective To investigate the effects of post-propofol anesthesia on cognitive function and hippocampus proteome expressions in aged rats.Methods Thirty healthy male Wistar rats aged 20 months were randomly divided into control group(n =15) and propofol group(n =15).The control group was injected with normal saline of 6 ml/kg intraperitoneally and propofol was injected intraperitoneally with propofol 60 mg/kg.The rats in both groups underwent Step-down Test to assess cognitive function at the first day and at the seventh day after the termination of drug administration.Five rats were decapitated randomly each time after the two step-down tests and their hippocampi were removed for two-dimensional gel electrophoresis and mass spectrometric analysis.Results In the step-down test,aged rats in the propofol group showed significantly learning impairment and decreased memory abilities at the 1st day after propofol anesthesia as compared with those in the control group.In learning phase of the 1st day,the latency of the propofol group is (29.5 ± 7.6)s as compared with(19.7 ± 7.0)s of the control group,while the error time is 3.6±1.2 vs.1.6 ±0.8 in the propofol group vs the control group,and the total time of electric shock is(65.2 t 10.6)s vs.(42.7 ± 10.3)s in the propofol group vs the control group(all P＜0.01).The latency of the memory phase in the propofol group is also decreased as compared with that in the control group(31.4±14.3)s vs.(111.2± 23.7) s,(P＜0.01).On the 7th day after anesthesia,there was no significant difference between the two groups.There were 17 differentially expressed proteins on the 1st day after propofol anesthesia,6 of them were up-regulated and 11 proteins were down-regulated (P ＜ 0.05).On the 7th day,there were 10 differentially expressed proteins,and the expression of 5 proteins was down-regulated (P ＜ 0.01).Conclusions Aging rats receiving propofol anesthesia show cognitive function decline,but do not show a long-term decline.The mechanism may be related to the different expressions of hippocampal proteins.
