1.Rho/ROCK and Neurological Diseases
International Journal of Cerebrovascular Diseases 2008;16(3):233-236
As a molecular switch,Rho can be transformed between the inactive GDP-bound form and the active GTP-bound form,transfering signals to downstream effector Rho kinase (ROCK),mediating specific biological effects,and participating in various neurological diseases, such as the pathological processes of ischemic stroke,cerebral vasospasm,and axonal regeneration after spinal cord injury.The application of ROCK inhibitor in the treatment of neurological diseases has achieved satisfactory effect.Rho/ROCK is expected to become a novel therapeutic target.

Objective To find out about community residents' demands and intentions for health service and explore new ways of delivering life-long health service. Methods An investigation was made via sending questionnaires to each household into the health conditions and demands and intentions for health service of 700 residents in 5 neighborhood committees and 1000 discharged patients as well as sub-healthy groups of people in a certain area in Nanchang. Results Of those surveyed, the two-week morbidity was 438 per thousand; the chronic morbidity was 574 per thousand; only 31.1% of the residents went to eommanity hospitals for medical service; and 63.4% of the residents never took any health care service while 59.6% of the residents thought it necessary to take health care service. Conclusion The masses of people are in dire need of low-price life-long medical service. Second-grade third-tier and second-tier hospitals in big and medium-sized cities may explore viable new ways of medical service that will meet the needs of society.

Objective To probe into the social support, coping styles, and mental health status of medical staff in a tertiary hospital in Beijing, for identifying potential mental problems. Methods Such means as the Social Support Rating Sheet (SSRS), Simple Coping Style Questionnaire (SCSQ), Symptom Checklist (SCL-90), and demographic characteristics questionnaire were called into play, to study 2460 medical staff in five tertiary hospitals in Beijing. Results Differences were identified among medical staff of different demographic characteristics, in terms of positive coping style and support dimensions. Analysis of the survey data indicates that the total SCL scores, total symptom problem index, positive symptom pain level, total average score of the factors, are positively related to passive coping style, as P<0. 01; and are negatively related to subjective/objective support, support utilization, and total support scores, as P<0. 01. Conclusions Hospital administration is expected to implement focused intervention to such medical staff as those under 40 years old, women, widows or divorcees, those with education lower than university degree, those with junior academic title or lower, those without titles, those in emergency departments and emergency intensive care units, doctors and nurses, frequent night-shift workers, those of excessively low self evaluation, and medical staff with chronic diseases. The purpose of this practice is to alleviate their mental stress.

OBJECTIVETo verify the pharmacological hypothesis of prescriptions by studying the targeted distribution of major components in stewed rhubarb in the rat model with acute pancreatitis (AP).
METHODNormal SD rats (control group, n = 5) and the AP model induced with intraperitoneal cerulein (model group, n = 5) were taken as the experimental objects. Rats of the two groups were orally administered with stewed rhubarb granules (20 g x kg(-1)). Their heart, liver, spleen, lung, kidney and pancreas were collected two hours after the administration. Such constituents as emodin, chrysophanol, physcion, rhein and aloe-emodin and their concentrations in each tissue homogenate were detected by high performance liquid chromatography-mass-mass.
RESULTAloe-emodin and physcion in stewed rhubarb whose concentrations in liver and kidney of normal rats were higher than that in pancreatic tissues, while the distribution spectrums and concentrations of the remaining components in pancreatic tissues had no significant difference with that of other organs. The concentrations of emodin, aloe-emodin, rhein and chrysophanol in stewed rhubarb in pancreatic tissues of the AP model group were higher than that in other tissues and organs, while their concentrations in pancreatic, renal and splenic tissues were notably higher than that in the normal group.
CONCLUSIONIn the conditions of AP, effective components in stewed rhubarb show a targeted distribution feature in pancreas, which provides experimental basis for the pharmacological hypothesis of prescriptions.

In the 1960s, modern science began involving the essence of heat syndrome, but there have still no in-depth systematic studies on pathological mechanisms of heat syndrome and action mechanisms of cold and cool herbs. In this study, the animal model with heat syndrome was set up by feeding herbs with hot property, and then cold and cool herbs was applied in the experimental therapy. The two-dimensional electrophoresis and mass spectrometry technologies were adopted to compare the liver mitochondria proteome of the rats of the heat syndrome model and the ones treated with cold and cool herbs, so as to discover specificity-related proteins after heat syndrome and treatment with cold and cool herbs.

Objective To evaluate the diagnostic value of 99Tcm-MDP SPECT/CT in the diagnosis of lumbar spondylolysis.Methods A total of 58 patients (28 males,30 females,average age 61.3 years) who underwent bone scan and SPECT/CT because of low back pain from January 2012 to May 2014 were retrospectively evaluated.The final diagnosis was based on comprehensive results of SPECT/CT and followup.The diagnostic sensitivity and accuracy of SPECT,CT and SPECT/CT images were calculated and x2 test was performed to analyze the data.Results Twenty-eight patients were diagnosed as lumbar spondylolysis.The diagnostic sensitivities of SPECT,CT and SPECT/CT were 53.6% (15/28),78.6% (22/28) and 100%(28/28).The diagnostic accuracies of SPECT,CT and SPECT/CT were 48.3% (28/58),89.7% (52/58) and 93.1%(54/58).SPECT/CT was proved to be more accurate than SPECT(x2=28.13,P< 0.05).Conclusion SPECT/CT bone scan may detect lumbar spondylolysis in early stage.

Objective To analyze the impact factors for early renal damage in type 2 diabetic patients by the classification tree model.Methods A total of 601 patients with type 2 diabetes were enrolled.According to glomerular filtration rates and urine albumin quantification,the patients were divided into type 2 diabetes group (418 cases) and early diabetic renal damage group (183 cases).The clinical data of the patients were recorded to analyze the main influential factors for the microalbuminuria of type 2 diabetic patients using the Exhaustive CHAID classification tree algorithm.Results Six important explanatory variables were screened out by the classification tree model from the 34 candidate variables related to early renal damage,including fibrinogen,history of hypertension,retinopathy,Cys C levels,SBP and peripheral neuropathy.Elevated fibrinogen was the main factor.Conclusion The classification tree model can analyze the major influential factors of early renal damage in type 2 diabetic patients effectively,and it can help develop the prevention and treatment methods.
