Social forces participating in non-profit medical institutions will help to insist on the commonweal of public medical and health care and realize the goal of access to basic medical and health services for everyone .At present , social forces participating in non-profit medical institutions have made some prominent improvements under a series of policy support .However , due to the absolute dominance of public hospitals , social forces participating in non-profit medical institutions are still potting a lot of restrictions on access threshold of basic medical services , devel-opment space and policy implementation .In order to promote the healthy development of social forces participating in non-profit medical institutions , we should first recognize its significance and guarantee its development potential , tal-ents construction and development space through implementing preferential policies , improving supervision mecha-nisms, exploring multi-sited license, optimizing allocation of resources and so on .

Objective To evaluate the neuroradiological features of intraventricular central neurocytoma in ten patients.Methods Ten patients with central neurocytoma were imaged using contrast-enhanced and non-enhanced MRI scans,including 4 were also scanned with non-enhanced CT.The imaging data were studied with regard to location,size,margin,signal intensity,enhancement characteristics and presence of calcifications.Clinical data(i.e.presenting signs and symptoms,physical findings and medical history) were collected and histopathological and immunohistochemical studies were performed.Results There were 4 male,6 female in our group.All lesions were located in the lateral ventricles.Three tumors were confined to the left side,three to the right side and four involved both lateral ventricles.The growth of central neurocytoma was of close spatial relation to the septum pellucidum.In MRI,most of the cases showed a heterogeneous hypointensity on T1WI and hyperintensity on T2WI or FLAIR with a well-defined margin.The presence of cystic components,necroses and calcifications had been the cause of these internal heterogeneities.After intravenous administration of gadolinium(Gd-DTPA) all tumors showed a heterogeneous enhancement.CT provided additional information by distinguishing intratumoral calcifications in all four evaluated cases.Conclusion Central neurocytoma should be considered when young patients with lesions in the lateral ventricle,which contain calcifications and show some enhancement.This is especially applicable for tumors involving both lateral ventricles with symmetrical growth around the center of septum pellucidum or for unilateral ventricular tumors with a wide base attachment to the septum pellucidum.

OBJECTIVE:To establish a RP-HPLC method for determination of the content of hydrochlorothiazide tablets.METHODS:Samples were determined by RP-HPLC on a ZORBAX SB-C 18 column with a mixture of phosphate buffer solution(pH=4.0)-methanol(80∶20)as mobile phase and UV detection at226nm.RESULTS:The calibration curves of hydrochlorothiazide was linear from0.006to0.303mg/ml(r=1.0000,n=5),the average recovery and relative standard deviation were100.1%and0.43%(n=9)respectively.CONCLUSION:The method is rapid,simple,accurate and precise.It can be used for assay of hydrochlorothiazide.

Objective To explore the correlation between serum homocysteine (Hcy) level and diabetes mellitus combined with cerebral infarction (DMCI) in patients. Methods A total of 144 patients with type 2 diabetes mellitus (T2DM) were selected and divided into two groups, patients without cerebral infaction (group A, n=64) and patients with cerebral infaction (group B, n=80). Thirty healthy people were used as control group (group C). The serum Hcy level was detected by enzymatic cycling assay in three groups. The serum levels of cholesterol (TC) and triglyceride cholesterol (TG) were detected by enzymatic determination. The serum levels of high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C) were detected by homogeneous phase method. The serum level of creatinine (Cr) was detected by creatine oxidase method. The level of uric acid (UA) was detected by urinary enzyme peroxidase coupling method. Glycosylated hemoglobin (HbA1c) was detected by high performance liquid chromatography. The carotid artery intima media thickness (IMT) was examined by color Doppler ultrasound, and patients were divided into mild and no stenosis group, moderate stenosis group and severe stenosis group according to the
results. The levels of Hcy were compared between all groups. The correlation of Hcy level and other indicators was analyzed. Results The levels of Hcy and HbA1c were group C0.05). There were no significant differences in UA and Cr levels between the three groups (P>0.05). The level of Hcy was positively correlated with age (rs=0.411), HbA1c (rs=0.219) and Cr (rs=0.242), and negatively correlated with gender (rs=-0.202) and HDL-C (rs=-0.278, P<0.05). There were no significant correlation between Hcy level and other variables (P>0.05). With the increased degree of carotid artery stenosis, the Hcy level and the proportion of HHcy showed a rising trend in patients (P<0.01). The level of Hcy was positively correlated with IMT(rs=0.781, P<0.001). Conclusion Hcy is a risk factor for the onset of DMCI. The high level of Hcy is closely related to the occurrence and progression of atherosclerosis. Hcy has great value for early screening and prevention of DMCI.

Objeetive To investigate the clinical effects and nursing interventions of endoscopic sphincterotomy(EST)for treating elderly patients with choledocholithiasis.Methods The clinical data of 73 cases of patients operated by EST were retrospectively analyzed.Before surgery the psychological nursing,examination and preparation were meticulously performed,the changes of vital signs and nursing were closely observed during surgery,the respiratory tract nursing,cardiovascular disease and diabetes nursing,pain nursing and complications treatment were performed after surgery.Results There were 69cases of 73 patients were successful,the success rate was 94.5%;8 cases of concurrent hyperamylasemia were given conservative treatment and had clinical recovery;2 cases of fever occurred and white blood cell count elevated and were treated by effective antibiotic treatment;there was no perforation,wound bleeding and death.Conclusions Using the EST to treat the choledocholithiasis of elderly patients has good clinical effects and low risk;through careful observation and nursing,can reduce complications,promote the patients'early recovery and improve quality of life of elderly patients with choledocholithiasis.

Clinical data of 6 children with retrocaval ureter were retrospectively analyzed.Diagnoses were mainly based on ultrasound-guided high-dose venous urography,computed tomography(CT)or renal dynamic imaging(single photon emission computed tomography).Surgical operation was the optimal treatment of choice,resulting in different improvement in hydronephrosis but no anastomotic stenosis.

Objective To study the apoptosis-inducing effect of histamin-indomethacin（his-IN）on Lewis lung cancer cell in mice.Methods The suspension of tumor cells from Lewis lung cancer mice was inoculated into the left axilla of Kunming mice.When the tumor grew to 1 cm in diameter,the mice were divided into 5 groups and received corresponding treatment：3.0 mg/kg indomethacin（IN）group,3.5 mg/kg IN group,3.0 mg/kg his-IN group,3.5 mg/kg his-IN group,and saline control group.Ten days later,the therapeutic effects were evaluated by the tumor inhibitory rate,the apoptotic peak and rate of tumor cells were measured by flow-cytometry（FCM）,and tumor necrosis factor α（TNF-α）level was estimated by radio-immunity method.Results TNF-α level,the tumor inhibitory rate and the apoptosis rate of his-IN group and IN group were significantly higher than those of the control group,and those of 3.5 mg/kg his-IN group was the highest.In the groups of his-IN or IN treatment,an apoptotic peak was found before G0/G1 phase,and the peak in his-IN group appeared earlier than IN group.Conclusion IN and his-IN could resist the growth of the tumor and promote cell apoptosis of Lewis lung cancer in mice.
