Objective To explore different construction models and experiences of clinical laboratory centers under exist-ing Integrated county healthservices entity,analyze and discuss the characteristics of various construction models,and provide ref-erences for the development of county-level clinical laboratory centers.Methods Based on the five factors of"man,machine,material,method,and environment"in Total Quality Management theory,an interview outline and questionnaire were designed for county-level clinical laboratory centers.Eleven county-level clinical laboratory centers across the country were investigated to analyze their construction models,investment returns,and other aspects.Literature reviews and case studies were also conducted to summarize the construction models and characteristics of county-level clinical laboratory centers.Results The construction models of county-level clinical laboratory centers are mainly divided into five types,each with distinct features.Through an analy-sis of the investment returns of these models unde rIntegrated county healthservices entity,it was found that a profit distribution ratio of approximately 5∶5 between county-level clinical laboratory centers and township health centers for referred samples is more conducive to maintaining the stability of sample sources.The construction model of county-level clinical laboratory centers is closely related to the medical service capacity of both county and township levels.Conclusion Counties with stronger county hospital capabilities tend to establish relatively independent regional laboratory centers based on the county hospital's laboratory department.Regardless of the model,the primary goal of county-level clinical laboratory centers should be to provide high-quality testing services coverage across the entire county.The key to the success of county-level clinical laboratory centers lies in motiva-ting grassroots personnel.

Objective:To investigate whether ginkgo biloba extract(EGb) can improve the symptoms of tardive dyskinesia(TD) by increasing the levels of serum brain-derived neurotrophic factor (BDNF), and to explore whether the BDNF Val66Met genotype can influence the efficacy of TD by EGb.Methods:A total of 78 male schizophrenia inpatients with TD were enrolled, and 77 patients completed 12 weeks of treatment with EGb(240 mg/d). The abnormal involuntary movement scale (AIMS), positive and negative syndrome scale (PANSS) and serum BDNF levels were measured at before and after 12 weeks of treatment.Serum BDNF levels were measured by enzyme linked immunosorbent assay (Elisa). In addition, the BDNF Val66Met polymorphism was genotyped by the method of PCR-restriction fragment length polymorphism (PCR-RFLP) in all patients.Results:Compared with before treatment, the scores of total AIMS((7.0±2.9) vs (4.9±2.2)), total PANSS ((55.8±14.0) vs(51.1±9.7)), subscale P((9.6±3.3) vs (8.6±2.2)), subscale N((23.2±8.3) vs (21.4±6.3)) and subscale G((23.0±4.9) vs (21.1±2.7)) were significantly decreased( P<0.01), while the levels of BDNF were significantly increased((10.8±2.9)μg/L vs (9.6±3.3)μg/L, P<0.05) in TD patients after treatment.The increased level of BDNF was positively correlated with the decrease of AIMS( r=0.28, P=0.014), but no significantly correlated with the improvement of PANSS total scores and the three subscales were found(all P>0.05). After treatment, the decrease of AIMS in patients with Val/Val genotype was significantly greater than that in patients with Val allele (Met/Val plus Met/Met genotype) (both P<0.05). Further analysis showed that only patients with Val/Met heterozygotes had a significant increase in BDNF levels after treatment ( P<0.05). Conclusions:EGb may improve TD symptoms through neuroprotective and regulatory effects.The BDNF genotype is involved in regulating the efficacy of EGb in the treatment of TD, which may be related to its regulation of BDNF serum levels.

To investigate if ginkgo biloba extract (Egb-761) can improve tardive dyskinesia (TD) symptoms through increasing the activity of plasma MnSOD. Methods We enrolled a total of 384 schizophrenia patients including 157 TD patients and 227 non-TD patients, as well as 280 normal subjects. The difference of MnSOD level in plasma among these groups were compared. TD patients were then randomly divided into two groups. The treatment group (n=77) and the placebo group (n=75) were treated with 240 mg of Egb-761 or placebo per day for 12 weeks, respectively. The abnormal involuntary movement scale (AIMS) and the positive and negative symptoms scale (PANSS) were used to evaluate the severity of the symptoms in baseline, the sixth week and the twelfth week after treatment. The level of MnSOD activity in plasma was also detected before and after the treatment. Results The level of MnSOD activity was lower in schizophrenia groups than in healthy control group (P＜0.01). In addition, the level of MnSOD activity was significantly lower in TD group than in non-TD group (P＜0.05). Repeated measures analysis of variance showed that group effect (F=4.00, P=0.05), time effect (F=32.17, P＜0.01) and interactive effect of group and time (F=39.04, P＜0.01) were significant in AIMS total score. The AIMS total score of treatment group was significantly lower than that of placebo group at 6-week and 12-week time points (all P＜0.01). Repeated measures analysis of variance showed that time effect (F=23.04, P＜0.01) and interactive effect of group and time (F=6.41, P＜0.05) were significant in the level of MnSOD activity. In addition, the level of MnSOD at baseline was significantly correlated with the reduction of AIMS total score during the treatment period (r=0.27, P=0.018). Conclusion Treatment of Egb-761 can improve symptoms of TD and activity of MnSOD.

The article chiefly explore the mechanism and treatment procedure on points emotional freedom technique (PEFT), The research methods include related literatures in combination with the Traditional Chinese Jing-Luo Theory, traditional Chinese psychology theory, modern psychotherapy theory and clinical practice. The mechanism of PEFT is clarified, and the features and treatment procedure of PEFT are summarized. PEFT was operationally simple and structuralized, and has significant characteristic of Traditional Chinese Medicine and definite effect.
