Objective:To summarize the current policies and measures in curbing health corruption in China, and to evaluate the implementation results of these policies and measures.Methods:We made a systematic review to search and screen the literatures, with related thematic information extracted, compared and classified to form an integrated view by the data integration method of thematic synthesis.Results:A total of 147 literatures were included, covering such health policies and measures as the basic drug system, the centralized bidding and purchasing and centralized drug purchasing, the " two-invoice system" , hospital information disclosure system, adverse records of commercial bribery, doctor′s virtue evaluation system and no bribery agreement. These five policies and measures prove effective in curbing the corruption, but some types of corruption tend to evade such restrictions.Conclusions:The five types of policy measures summarized in the study have effectively curbed the high risk exposure of corruptions found in drugs, medical consumables and medical devices, and also guided and restrained the profit-oriented behaviors of the behavior subjects. Stronger measures should be integrated into a broader reform of the healthcare system, in combination with institutional compensation and operational mechanism reform, medical personnel compensation and incentive system, and modern pluralistic governance reform. Meanwhile, studies in the field of corruption need to focus on the direct and indirect effects of multi-level medical reform policies on corruption governance from an integrated perspective, while attention needs to cover more types of corruption behaviors, and to diversify research methods, so as to provide more practical policy support.

Outpatient care services are usually the patient's first contact between the patients and the most bas-ic health care. The provision of outpatient care contributes to immediate and large gains in health status. The pay-ment method is one of the most common incentive methods applied by purchasers to guide the performance of outpa-tient care providers. This systematic review applied cochrane review method, and searched, screened, assessed and synthesized the relevant original studies. 19 studies were finally included. It was found that existing payment methods combined with P4 P interventions could probably slightly improved the health professionals' use of some tests and treat-ments ( adjusted RR median = 1 . 095 , range 1 . 01 to 1 . 17 ) , but may have led to little or no difference in patients' utilisation of health services ( adjusted RR median = 1 . 01 , range 0 . 96 to 1 . 15 ) and may have led to little or no difference in the control of blood pressure or cholesterol ( adjusted RR = 1 . 01 , range 0 . 98 to 1 . 04 ) . Pay for per-formance involves a complex design, each detail design may contain different incentive effect, therefore policy makers intend to apply pay-for-performance to guide the behavior of health providers, the design on each components of pay for performance should be analyzed in order to find more potential intervention points.

Objective:To evaluate the role of hemopexin (HPX) in cerebral ischemia-reperfusion (I/R) injury in rats.Methods:One hundred and twenty healthy male Sprague-Dawley rats, aged 7-8 weeks, weighing 250-280 g, were divided into sham operation group (S group, n=36), cerebral I/R group (I/R group, n=36), vehicle group (V group, n=24), and HPX group ( n=24). The model of cerebral I/R injury was established by 120 min middle cerebral artery occlusion followed by reperfusion in anesthetized rats.At 6, 12 and 24 h of reperfusion, 4 rats in S group and I/R group were sacrificed, and the ischemic penumbra of the ipsilateral cerebral cortex was obtained to detect the expression of HPX by Western blot.In I/R, V and HPX groups, 0.9% normal saline 10 μl, 0.1% NaN 3 10 μl, and 1.86 mg/ml HPX 10 μl were injected into the lateral ventricle, respectively, immediately after reperfusion.Eight rats in each group were selected, and neurological deficit was scored at 1-7 days of reperfusion.Eight rats in each group were sacrificed at 1 and 7 days of reperfusion, brains were removed, and brain tissues were obtained for measurement of infarct size, and the percentage of infarct size was calculated. Results:Compared with S group, the expression of HPX in cerebral ischemic penumbra was significantly up-regulated at 24 h of reperfusion in I/R group, and the neurological deficit scores were significantly decreased at 1-7 days of reperfusion, and the percentage of cerebral infarct size was increased at 1 and 7 days of reperfusion in I/R, V and HPX groups ( P<0.05). Compared with I/R group, the neurological deficit scores were significantly increased at 1-7 days of reperfusion, and the percentage of cerebral infarct size was decreased at 1 and 7 days of reperfusion in HPX group ( P<0.05), and no significant change was found in the above indicators in V and I/R groups ( P>0.05). Conclusion:Up-regulation of HPX expression is the endogenous protective mechanism of cerebral I/R injury in rats.

Objective To discuss the clinical and electrophysiological characteristics of sleep related rhythmic movement disorder ( SRMD).Methods We studied the clinical and electrophysiological characteristics of 3 patients diagnosed as SRMD in the Electroencephalography Monitoring Center of Xijing Hospital, Xi′an, China.The 3 patients accorded with diagnostic criteria of SRMD that international classification of sleep disorders-3 edition recommended and were followed up for more than 1 year.Results These 3 male patients were ranging from 6 to 27 years old.The onset age of the patient 1 was 13 years,and the others were 1 year old.The patient 2 became symptom-free at the age of 7.The patient 3 relieved at 2-year-old, but recurred at the age of 21. There was no epileptic seizure discharge in video-electroencephalography of the 3 patients, but synchronous electromyography changes during the attack were mistaken for slow wave.Video-polysomnography showed that numbers of awakenings and arousals index were high.Two patients were treated with clonazepam.One had an obvious curative effect, the other had marked efficacy until added trazodone.Conclusions SRMD can occur not only in infants, but also in adolescents and adults.Patients who have the problems of the sleep quality should be treated.Clonazepam can obviously relieve symptoms and improve sleep quality.Patients who do not have a good effect with clonazepam can try to add trazodone.Video-electroencephalography monitoring and interpreting it correctly are important to the diagnosis of paroxysmal disease.

Objective To explore symptom clusters and changes with time goes among inpatients of lung cancer to provide the basis for clinical nursing staff on symptom management. Methods Using the Chinese version of the M.D. Anderson Symptom Inventory (MDASI-C) and the revised lung cancer module on 217 cases of inpatients with lung cancer, and the follow-up after 1 month, 3 months by telephone. Results The result of principal component analysis of three times:there are same symptom clusters on three times evaluation, fatigue-related symptom cluster, lung cancer specific symptom cluster, chemotherapy-related symptom cluster and psychological symptom cluster. The first and third time assessment also contains respiratory symptom cluster. Over time some kinds of symptom clusters company with the disease trajectories. Fatigue-related symptom cluster is the major cluster and correlate to psychological and other symptom clusters. Conclusions Clinical workers should perfect the symptom management of patients all the time according to severity and changes of symptom clusters to benefit patients with lung cancer.

Objective To determine the effects of high-frequency jet ventilation (HFJV) on oxidative stress in patients during one-lung ventilation (OLV). Methods Forty-five patients undergoing elective radical esophageal cancer resection were divided into three groups with 15 cases each by random digits table: two lung ventilation group ( group A), OLV group (group B), HFJV- OLV group ( group C, working pressure 1 kg/cm2 and frequency 100 times/min). Venous blood samples were taken before induction (T0),at30min (T1),90min (T2),150min (T3) after OLV and the end of operation (T4) for measuring serum superoxide dismutase(SOD),malondialdehyde (MDA) and nitric oxide (NO). Results SOD was lower at T2-T4 in group B[(47 ± 10), (37 ±9), (41 ±7) kU/L] and group C[(58 ± 12), (51 ± 11), (49 ± 9) kU/L] than those in group A [(78 ±8), (75 ±7), (79 ±6) kU/L](P＜ 0.05),and MDA and NO were lower at T1-T4 in group B and group C than that in group A(P＜ 0.05). SOD was higher at T3 in group C than that in group B (P ＜ 0.05), MDA at T1-T4 and NO at T2-T4 were lower in group C than those in group B (P ＜ 0.05). Conclusion HFJV can effectively decrease oxidative stress in patients during OLV.

Aim:To develop a rapid high-performance liquid chromatography-mass spectrometry (HPLC-MS) method for the quantification of tiopronin in human plasma.Methods:Cysteine was chosen as antioxidant and firstly added into the whole blood firstly.After adding mycophenolic acid as internal standard (IS) and 1 mol/L HCl into the plasma,the samples were extracted with acetic ether and then determined by HPLC-MS.The chromatographic separation was performed on a Shim-pack VP-ODS C18 column (250 mm×2.0 mm,5 μm) using methanol-0.1% acetic acid (70∶30) as mobile phase with a flow rate of 0.2 mL/min.Results:The assay exhibited a linear range of tiopronin between 30～4 000 ng/mL.The precisions for intra- and inter-batch were all within 8.5%.The extraction recoveries were more than 70%.The total HPLC-MS analysis time was within 7.5 min per a run.The fully validated method was successfully applied to quantify tiopronin in human plasma for a bioavailability study.Conclusion:The assay proved to be accurate,sensitive,selective and convenient.The fully validated method can be applied to study the pharmacokinetics and bioavailability of tiopronin and tiopronin formulations in human.

In this study, real-time PCR and immunohistochemistry were used to detect coxsakie and adenovirus receptor (CAR) expression. Both localization and quantity were evaluated in the uteri obtained at days post coitus (dpc) 2.5, 4.5, 6.5, 8.5. Outcome of PCR was assessed by 2(-ΔΔCt) method. Image Pro-Plus 6.0 software was used for quantifying mean density of CAR expression in immunohistochemical sections. We found relatively weak CAR expression in the mouse uteri during implantation window. PCR and immunohistochemistry revealed highest CAR expression was detected on dpc 2.5 followed by down-regulation of CAR at dpc 4.5 and 6.5 (with significant difference). At dpc 8.5, CAR expression was increased slightly again. It is concluded that during implantation, the expression of CAR mRNA and protein is declined, resulting in the impairment of tight junction between cavity epithelium cells. After implantation window closure, CAR appears again to maintain epithelium stability. CAR might play an important role during embryo implantation procedure.

Nonalcoholic fatty pancreatic disease (NAFPD) is defined as pancreatic fat deposition associated with obesity in the absence of significant drinking, and its pathogenesis remains unclear. NAFPD is closely associated with nonalcoholic fatty liver disease (NAFLD), type 2 diabetes, pancreatitis, pancreatic tumor, and pancreatic fistula after pancreaticoduodenal surgery and can promote the spread of pancreatic cancer cells and result in the early death of patients with pancreatic cancer. The diagnosis and evaluation of NAFPD mainly rely on pathological biopsy and imaging examination, but their clinical application is limited by detection techniques and diagnostic level. Major prevention and treatment methods for NAFPD include a reduction in body weight, bariatric surgery, and pharmacotherapy. Since there are few articles on NAFPD and it is not taken seriously in clinical practice, there are significant differences in the clinical diagnosis and treatment of this disease. Therefore, this article elaborates on the current status of research on NAFPD and the advances in its diagnosis and treatment.
