1.Effects of HFJV outside of the glottis on the blood gas and lipid peroxidation in dogs with hemorrhagic shock
Chinese Journal of Pathophysiology 1989;0(05):-
18 dogs with hemorrhagic shock were divided into 3 groups. Group Ⅰwascontrol, group Ⅱ and Ⅲ were jetted with air or oxygen respectively and continuouslyoutside the glottis by HFJV (frequency 80 beat/min, driving pressure 0.2 MPa, I:E timeratio=1:2) during the uncompensated period. Results: Not much difference was foundbetween group Ⅰand Ⅱ in their blood gas, acid-base balance and plasma malondialdehyde(MDA). However, the P_aO_2, P_aCO_2, CO_2, combining power and plasma MDA in group Ⅲwere markedly higher than those of group Ⅰand group Ⅱ (P

Objective To evaluate the treatment of in-stent restenosis with rotational atherectomy and balloon angioplasty. Methods The rotational atherectomy and 4~6 atm low pressure balloon angioplasty was performed in 3 patients with in-stent restenosis and follow up after treatment. Results All cases were succeeded. The bradycardia occurred in one patient was quickly disappeared without treatment, two other patients were found no effect on heart rate, hemodynamic performance, global LV function, or regional wall motion. No complications, angina, death or other coronary event occurred during the follow up for 6~12 months. Two of them was performed coronary angiography after 6 months and showed the diameter of target vessel was less than 30% as compared with that on coronary angiography which performed immedately after operation. Conclusion The management of in-stent restenosis in target vessels using a combination of rotational atherectomy and balloon angioplasty is safe and efficient.

Objective To clarify the factors influencing development of cholecystopathy in schis-tosomiasis portal hypertension. Methods The data of 116 schistosomiasis portal hypertension patients from 1998 to 2002 were retrospectively analyzed and compared with non-liver disease pa-lients. Results Of the incidence of cholecystitis, the schistosomiasis portal hypertension patients vs non-liver-disease were 87.9% (102/116) vs 36.6% (15/41) (P0. 05). Of the incidence of cholecystolithiasis, the schistosomiasis portal hypertension patients vs non-liver-disease were 38.8% (45/ 116) vs 19.5% (8/0.41) (P0. 05). Conclusion The incidences of cholecystolithiasis and cholecystitis are closely correlated with portal hypertension in schistosomiasis, and are not closely correlated with hypersplenism.

An HPLC-UV method has been developed for the determination of valibose, miglitol, voglibose and acarbose, the four anti-diabetic drugs. The separation was accomplished successfully by using reversed phase chromatography (Prevail carbohydrate column, 250 mm x 4.6 mm, 5 microm) with a gradient acetonitrile-phosphate buffer solution (pH 8.0) at a wavelength of 210 nm. Furthermore, the method of a high-performance liquid chromatography coupled with ESI-MS in positive ionization mode has been established. These two methods were successfully applied to the assay and qualitative detection of four alpha-glucosidase inhibitors in the potential counterfeit anti-diabetic drugs.

Objective:To explore the value of stress hyperglycemia ratio (SHR) in predicting the prognosis of patients with acute heart failure (AHF).Methods:AHF patients admitted to the Emergency Department of Shanghai Jiao Tong University Affiliated Sixth People's Hospital from December 2016 to January 2019 were retrospectively included. Clinical data were recorded and SHR was calculated. According to the survival of the patients within 1 year, they were divided into the death group ( n=89) and the survival group ( n=218). Logistic regression analysis was used to analyze the risk factors of mortality. Kaplan-Meier analysis was used to evaluate the correlation between SHR and the prognosis of AHF patients. Results:A total of 307 patients aged 83 ( range 74-87) years old who met the inclusion criteria were included in this study, including 153 males and 104 females. The age, SHR and N-terminal prohormone of brain natriuretic peptide (NT-proBNP) in the death group were higher than those in the survival group [84 (78, 88) vs 82 (72, 86), 1.11 (0.91, 1.51) vs 1.02 (0.86, 1.27), 5 351 (2 098, 14 039)μg/L vs 4 243 (2 294, 7 565)μg/L ]. The left ventricular ejection fraction (LVEF) in the death group was significantly lower than that of the survival group [53 (45, 57) % vs 58 (44, 64) %, P< 0.05]. Logistic regression analysis showed that SHR was an independent risk factor for death in AHF patients ( OR=2.397, 95% CI: 1.285-4.471, P< 0.05). Median SHR was used to draw the survival curve. Patients with high SHR had a lower cumulative survival rate, and the difference was statistically significant ( P<0.05). Conclusion:SHR can identify critically ill patients and is an independent risk factor for death in AHF patients.

Objective To design a wireless monitoring system which can obtain patients' multi-parameters (such as ECG, respiratory, blood pressure, SPO2, and heart rate). Methods The wireless communication system, based on CDMA, receives data through internet and analyses ECG by dealing and measuring signals. Results A wireless monitoring system is designed, which can analyse ECG, blood pressure, and respiratory. Doctors can give diagnostic suggestion based on the monitoring system's analyses and send it to patients by short messages. Conclusion This system can realize long -distance medical monitoring and report the diagnosis to patients timely.

Objective To develop a portable sleep monitoring system with low burden. Methods Information from signals related with sleep were used and dug. Electrodes from patients' body were reduced to decrease patient's physiological and psychological burden. Results Polysomnography(PSG) is the gold standard in detecting the Sleep Apnea Hypopnea Syndrome disease at present. While this method has its problems, such as complicated operation, large expenditure and big physiology and psychology burden for the patient. A sleep monitor system was introduced which has the advantages of convenience, practicality, small physiology and psychology burden for the patient. Conclusion The result indicates that this device is warmly welcomed by doctors and patients, and it is a new device for the diagnosis of the SAHS disease.

Objective To determine whether rTFPI could inhibit vascular thrombosis and salvage random pattern skin flaps following AIRC in rat models.Methods From April,2013 to June,2015,30 adult male Sprague-Dawley rats were randomized into 3 groups;a control group,an avulsion injury with roll compaction (AIRC) group,and an AIRC plus rTFPI therapy group.An 8.0 cm× 2.5 cm random flap was raised on the dorsum of each rat.The AIRC and AIRC plus rTFPI flaps were then altered with a device designed to simulate avulsion injury with roll compaction.After flap closure primarily,treatment was initiated immediately and continued for 3 days.Phosphate buffered saline was used in the control group and the AIRC group,while the AIRC plus rTFPI group received the recombinant Tissue Factor Pathway Inhibitor.Laser Doppler flowmetry and infra-red thermalgraphy were used on postoperative day three to assess nicrocirculatory blood flow and viability of the avulsed flaps.At postoperative day seven,final flap survival was determined.Using SPSS19.0 statistical analysis.Results The flap survival in AIRC group was only (32.7 ± 5.2)% versus (62.5 ± 6.5)% in control group,but the flap survival significantly increased (51.6 ± 8.2)% after topical injecting rTFPI in experimental group.Statistically significant differences exist (P < 0.05) between every two groups.The detection results of Laser-Doppler flowmetry and infra-red thermography showed that perfusion arrived the centre of the flaps in experimental group,while perfusion only arrived the proximal part of the flaps in the AIRC control group.Conclusion rTFPI therapy is effective in reducing ischemic necrosis of random pattern flaps following avulsion injury in the rat model.It suggests that rTFPI therapy may play an important role in clinical salvage of the failing avulsion injuries with roll compaction.
