The half-closed loop feedback controlling is used in the design.The CPU analyzes the pressure,volume and signals,then adjusts operating condition to realize the automatic gastric lavage,display,back rinse,alarming,etc.

We observed 38 patients' breath frequency after different oxygen therapy according to their visit sequences and tolerance conditions.All patients with chronic obstructive pulmonary.disease (COPD) plus carbon dioxide retention from April 2008 to June 2011 were recruited at our hospital.Twentythree patients who could maintain SpO2≥92％ through inspiring O2 at ≤3.5 L/min were assigned into the first group.And another 15 subjects whose SpO2 could not reach 92％ at the same oxygen flow for 5 hours were assigned into the second group.The second group received an elevated oxygen flow until their SpO2 attained 92％ or so.But the maximal rate did not exceed 8 L/min even if SpO2 was below 92％.The state was maintained for 5 hours.Paired t-test showed PaO2 became elevated and PaCO2 decreased significantly on onset and termination of low oxygen flow in both groups.But the frequency of the second group's breaths per minute (BPM) had no significant differences.After elevating oxygen flow,the second group's BPM and PaCO2 on onset and termination were (19.4 ± 3.4) and (18.1 ± 2.6) perminute (P =0.038),(55.0 ±8.1) and (52.0 ±7.9) mm Hg (1 mm Hg =0.133 kPa) (P =0.030) respectively and the results showed significant decreases.But SpO2 was elevated [(85.8 ± 4.1) and (90.7 ± 2.4) mm Hg (P =0.000)].

Objective To research the curative effect of the chronic refractory skin ulcer,which belong to yang deficiency of both spleen and kidney type with the treatment of Huiyang Shengji ointment,and discuss the mechanism at cell and molecular level.Methods According to the diagnostic criteria,102 patients were divided into the treatment group(treated with topical Huiyang Shengji ointment) and the control group(treated with topical chlorhexidine).The effects were summarized six weeks later.The marginal tissue of the patients with the chronic skin ulcer was taken to analyze collagen Ⅰ/Ⅲ with the software and the expression of cytokine FGF-2,VEGF,Fn were observed during the wound heal.Results The effective rate was 50% in the treatment group,the control group was 33.33%,with statistical differences.Huiyang Shengji ointment can change the status of the chronic wound,promote growth of new blood vessels and improve the collagen synthesis,especially collagenⅠ.The expression of the FGF-2 and VEGF in the marginal tissue of the chronic skin ulcer showed a rising trend.Conclusions Huiyang Shengji ointment can accelerate the wound heal of chronic refractory skin ulcer.One of the mechanisms is related to promoting growth of new blood vessels and improving the collagen synthesis.

ObjectiveTo investigate the character of severe cognitive deficit caused by topiramate(TPM) administration in epileptic patients.Methods3 epileptic patients who suffered from severe cognitive deficit following topramate treatment were analyzed.Results and ConclusionTheir verbal functions were often affected especially the fluency of speech, as well as their memory and calculation.

Objective To investigate the relationship between cerebral thrombosis and iron-deficiency anemia, and their clinical manifestations and therapy. Methods The clinical data of 4 patients with iron deficiency anemia complicated by cerebral thrombosis were analyzed retrospectively. Results Four patients were moderate-to-sexere anemia with thrombocytosis, and their blood pressure was relatively low. Two had chronic infection foci. All patients had cerebral infarction in the internal carotid system, of those, 2 were weatershed infarctions, and 2 were basal ganglia infarctions. Oxygen inhalation, correcting anemia, adjusting blood presssure to an appropriate level, and other conventional treatment were effective. Conclusions The patients with moderate-to-severe anemia, such as accompanied by thrombocytosis and lower blood pressure, are easy to came thrombosis. While in the routine treatment of cerebral thrombosis, attention should be paid to finding the causes of anemia and correcting them.

Objective To compare the effect between bilevel positive airway pressure (BiPAP) and routine drugs treatment to patients with obstructive sleep apnea hypopnea syndrome ( OSAHS ) complicated with stroke. Methods Twenty-nine patients with OSAHS complicated with stroke were randomly divided into two groups, 15 cases in the treatment group and 14 cases in the control group. Patients in the treatment group were applied BiPAP and routine drugs including degrading intracranial pressure, promoting blood flow, improving microcirculation. BiPAP were maintained for two months and over 10 hours daily. The control group was executed only routine drugs treatment. Results The difference of apnea hyponea index( AHI) and frequency of below 90% O2 saturation during sleep time between pre-therapy and post treatment was significantly higher in the treatment group(36. 8 ± 10. 7 and 105. 3 ± 17. 9) than in the control group (20. 8 ± 8. 1 and 44. 4 ± 24. 3 ) ( P < 0. 01 ) . The difference of lowest nighttime SaO2 between pre- and post-therapy was significantly higher in the treatment group( - 11. 7 ±8. 1)% than in control group(-2. 0 ± 8. 9) % ( P <0. 01). The difference of neurologic impairment score was significantly higher in the treatment group ( 16. 0 ± 2. 6) than in the control group ( 10. 1 ± 3. 6) ( P < 0. 01 ) . As for whole blood viscosity and red blood cell aggregation index,there was no significant difference between pre- and post-therapy(P> 0. 05). Conclusions BiPAP combined with routine drugs can significantly improve sleep anapnea indexs and neurologic impairment scores in patients with OSAHS complicated with stroke than only drug treatment. Blood rheology's indexs could not obtain amelioration in short period.

Objective To provide references for rational clinical usage and purchase of TCM decoction pieces for blood-activating and stasis-removing. Methods Excel 2013 software was used to conduct statistical analysis on categories, consumption quantity, consumption sum and annual average growth rate of TCM decoction pieces for blood-activating and stasis-removing during 2011-2015 in TCM Hospital of Jiangsu Province (hereinafter refered to as our hospital). Results The consumption quantity and consumption sum of TCM decoction pieces for blood-activating and stasis-removing in our hospital increased year by year. Among all types of TCM decoction pieces for blood-activating and stasis-removing, TCM decoction pieces for activating blood and adjusting maridians occupied the largest amount, followed by TCM decoction pieces for activating blood and relieving pains, breaking up the static blood and eliminating masses, and blood-activating and wound - curing. The TCM decoction pieces with the biggest annual consumption quantity were Salviae Miltiorrhizae Radix et Rhizoma, Chuanxiong Rhizoma, and Curcumae Radix, and the TCM decoction pieces with the biggest annual consumption sum were Notoginseng Radix et Rhizoma, Salviae Miltiorrhizae Radix et Rhizoma, and Carthami Flos. Conclusion Both the consumption quantity and the consumption sum of the TCM decoction pieces for blood-activating and stasis-removing in our hospital have been increasing year by year. However, the proportion consumption quantity and the consumption sum of TCM decoction pieces and medicine utilization structure have kept stable, and in basically rational use.

Very low-density lipoprotein receptor(VLDLR)is a transmembrane lipoprotein receptor and plays an important role in the disorder of lipid metabolism in diabetes.The finding of changes in expression and distribution of two subtypes of VLDLR in diabetes as well as the effective VLDLR gene therapy in hyperlipidemia have drawn attention to the VLDLR as a potential target for prevention of abnormal lipid metabolism in diabetes.
