To retrospectively analyze the clinical data of 305 cases with apoplectic sequela admitted at our general geriatric nursing ward from January 2000 to December 2011.The subjects were divided into 2 groups:hypoalbuminemia and non-hypoalbuminemia.Advanced age (OR =5.624),chronic heart failure (OR =2.298),conscious disturbance (OR =1.575),dysphagia (OR =1.565),complete bedridden (OR=2.874),pneumonia (OR =3.725) and bedsore (OR =5.336) were risk factors for hypoalbuminemia in the patients with apoplectic sequela.And hyperglycemia(OR =0.066)was a protective factor for it.

Objective To explore the related factors of the relapse of schizophrenics in unwell developed economic areas.Methods To analyze 718 schizophrenics by single and multiple stepwise regression analyses to explore whether relapse of schizophrenia was related to those factors.Results 2.8％ experienced one time relapse, 14.2％ experienced two times relapse and 83％ three times. The rate of schizophrenic relapse was in turn correlated with treatment compliance, treatment intervention, marriage, clinical features, psychological stress,social support, the way of forming disease, medical expenses and condition of access to medical care. Conclusions More attention should be paid to the factors causing schizophrenic relapse and wider measures of prevention and treatment should be taken.

BACKGROUND: Inadequate hyperventilation may trigger cerebrovascular contraction and lead to lowered cerebral perfusion and oxygen supply-demand imbalance.OBJECTIVE: To investigate the influence of hyperventilation on oxygen saturation in the internal jugular vein, difference in oxygen and lactic acid contents between the cerebral arteries and veins in patients with serious traumatic brain injury.DESIGN: Case analysis.SETTING: Department of Anesthesiology, First Hospital Affiliated to Shantou University.PARTICIPANTS: Sixteen patients who received emergency operations in the First Hospital Affiliated to Shantou University between January and July 2002.METHODS: Patients with traumatic brain injury underwent operation under general anesthesia, and the PaCO2 was maintained at 30 mm Hg for 15 minutes by regulating the respiration rate, followed by decrease to 25 mm Hg, maintained for 15 minutes before restoration to 30 mm Hg for 15 minutes. The fractional concentration of inspired oxygen was adjusted to maintain blood PaO2 at around 100-150 mm Hg, and the blood sample was collected from the artery and internal jugular vein 15 minutes after adjustment of PaCO2 for blood gas analysis. The PaO2 was then increased to 200-250 mm Hg by increasing the fractional concentration of inspired oxygen, and the PaCO2 was adjusted from 30 to 25 and then back to 30 mm Hg in the described manner, and the oxygen saturation in the internal jugular vein, difference in oxygen and lactic acid contents between the arteries and the veins were measured.MAIN OUTCOME MEASURES: Influence of blood PaO2 and PaCO2 on oxygen saturation in the internal jugular vein, difference in oxygen and lactic acid contents between the arteries and the veins.RESULTS: Sixteen patients met the diagnostic criteria and completed data collection. The arterial PaCO2 decreased from 30 to 25 mm Hg when arterial blood oxygen pressure increased from 100-150 to 200-250 mm Hg, which leads to obvious decrease of oxygen saturation in the internal jugular vein and obvious increased difference in oxygen content between the cerebral artery and vein. However the absolute value of oxygen saturation in the internal jugular vein was obviously higher at PaO2 of 200-250 mm Hg than that at PaO2 of 100-150 mm Hg, while the absolute value of cerebral arteriovenous difference of brain oxygen content was obviously lower. Compared to the basal level, the arteriovenous lactic acid difference was obviously increased at PaO2 of 100-150 mm Hg,PaCO2 of 30 and 25 mm Hg, and at PaO2 of 200-250 mm Hg and PaCO2 of 25 mm Hg.CONCLUSION: Relatively higher PaO2 (200-250 mm Hg) and mild hyperventilation (PaCO2 of 30 mm Hg) has no obvious effect on brain oxygen supply-demand balance.

Objective To establish a method for the quantitative determinations of the ingredients in yiqi hewei capsules. Methods RP-HPLC method was used. The separation was performed on a Thermo C18 column with mobile phase consisting of acetonitrile-water (20: 80) (pH was adjusted to 3 with glacial acetic acid) at the flow rate of 1. 0 mL·min-1. The detection wavelength was 283 nm. Results The linear ranges were ( 0. 5735 -5. 7360) × 10 -2 mg·mL-1 for baicalin, (0. 1940-1. 9395) × 10 -2 mg·mL-1 for hesperidin, (0. 2051 -2. 0510) × 10 -3 mg·mL-1 for naringin and (0. 2020 -2.0200) ×10 -2 mg·mL-1 for neohesperidin;RSD =0.28%,0.54%,0.54%,0.31%(n =5),respectively. The average recoveries were 103. 94%, 98. 06%, 103. 09%, 95. 67%, respectively. Conclusion The established method is simple, sensitive and accurate,which can be used for the quality control of yiqi hewei capsules.

In mice, adriamycin (l7.5mg/kg, ip ) produced heart peroxida-tion abnormality including increased TBA value & decreased gluta-thione peroxidase activity, respectively. But the change of former was not parallel to the latter. The drug also produced early pathological change of the heart i.e. more D-PAS positiveness. The results suggested that the early heart pathological change produced by adriamycin may be related to increased accumulation of pero-xi dative products.

Objective To observe the pain behavior of rats with Oxaliplatin‐induced peripheral neuropathy(OXIPN)and cal‐citonin gene related peptide(CGRP)expression.Methods Twenty Wistar rats were randomly divided into 2 groups :normal con‐trol group and model group.Oxaliplatin(20 mg/kg)was injected intraperitoneally to the rats in the model group.Mechanical pain threshold and cold allodynia were detected before and 6 ,24 ,72 h and 7 days after modeling ,respectively.Western blot and im‐munohistochemical method were employed to measure the expression of CGRP in dorsal spinal root ganglion of control group and model group.Results The mechanical pain threshold of modal group rats decreased 6 h after injection of Oxaliplatin as compared with the normal group[(11.6 ± 2.2)g vs. (13.9 ± 3.7)g] ,and decreased with prolongation of time ,reduced to the lowest at 72 h[(3.9 ± 1.4)g]and maintained to day 7 ,and the same trend was found in cold chemical allodynia test.CGRP ex‐pression of dorsal root ganglion increased significantly in the model group rats ,and there was a significant positive correlation between the expression of CGRP and the degree of mechanical pain threshold.Conclusion CGRP plays an important role in Ox‐aliplatin‐induced central sensitization of rats with peripheral neuropathy.

In the article, it thinks that moral lacking of advertisement is the basic reason which leads to intensified illegal medical advertisement. The main reasons for moral lacking of advertisement: imperfect legal system of medical advertisement, indifferent ethical consciousness of medical advertisement, insufficient social supervision of medical advertisement. Therefore, we should perfect the legislation, establish the correct advertising moral concept, improve the quality of advertising employees, and realize the function of social supervision fully.
