OBJECTIVETo observe the clinical therapeutic effect and side effect of pressure-control ventilation (PCV) on traumatic acute respiratory distress syndrome (ARDS) compared with volume-control ventilation (VCV).

METHODSForty patients with traumatic ARDS were hospitalized in our department from June 1996 to December 2002. Twenty were treated with PCV (PCV group) and 20 with VCV (VCV group). The changes of the peak inflating pressure and the mean pressure of the airway were observed at the very beginning of the mechanical ventilation and the following 12 and 24 hours, respectively. The transcutaneous saturation of oxygen pressure, the pressure of oxygen in artery, the mean blood pressure, the central venous pressure, the heart rate and the incidence of the pressure injury were also monitored before ventilation and 12 hours after ventilation.

RESULTSThe pressure of oxygen in artery, the transcutaneous saturation of oxygen pressure, the heart rate and the respiratory rate in the PCV group were obviously improved after ventilation treatment. The peak inflating pressure, the mean pressure of the airway and the central venous pressure in the PCV group were lower than in the VCV group. The incidence of pressure injury was 0 in the PCV group while 10% in the VCV group.

CONCLUSIONSThe clinical effect of PCV on traumatic ARDS is better and the incidence rate of pressure injury is lower than that of VCV. PCV has minimal effects on the hemodynamics.

BACKGROUNDUp to date, there is few satisfactory pharmacotherapy, except for aspirin and heparin, to stop the preeclampsia progression. Although the mechanism of preeclampsia is poorly understood, it has been proven to be associated with coagulation activation. Researches on prophylactic and therapeutic application of anticoagulants may benefit the clinical aspects of preeclampsia individuals. This study aimed to evaluate the effects of Danshensu on maternal syndrome in phosphatidylserine/phosphatidylcholine (PS/PC) microvesicle induced-mouse model.

METHODSSixty-six preeclampsia-like pregnant mice, induced by PS/PC microvesicle administration, were randomly divided into six groups. From days 5.5 to 16.5 of pregnancy, each group was respectively treated as follows: a) mice in group C (n = 12, control group) were injected with 100 microl of filtered phosphate-buffered saline into the tail vein every day; b) group PE (n = 15, preeclampsia model group) were injected in the same way with 100 microl of filtered PS/PC vesicle suspension; c) group H (n = 9, group treated with heparin) were injected with 1 unit heparin together with PS/PC vesicle suspension; d) group A (n = 10, group treated with aspirin) were injected with 20 microg/g aspirin-DL lysine as well; e) group LD (n = 10, group treated with low-dose Danshensu) were injected with 10 microg/g Danshensu; and f) group HD (n = 10, group treated with high-dose Danshensu) were injected with 30 microg/g Danshensu. Systolic blood pressure, total urinary protein levels, blood tests for some hemostatic function parameters (mean platelet counts, plasma antithrombin III activity (AT-III), D-D dimmer levels, and thrombin time), fibrin deposition by phosphotungstic acid hematoxylin staining, and thrombomodulin expression by immunohistochemistry staining in placentas were examined as indices for maternal syndrome.

RESULTSHeparin showed significant effects on maternal syndrome of preeclampsia such as hypertension and proteinuria, and different doses of Danshensu also presented the certain effects. High-dose Danshensu and aspirin all demonstrated better effects than low-dose Danshensu on decreasing blood pressure to normal level, while high-dose Danshensu demonstrated better effects than aspirin and low-dose Danshensu on decreasing proteinuria to normal level. As to Danshensu's effects on hemostatic function, high- and low-dose Danshensu's marked effects on increasing the plasma AT-III activity were the same as that of aspirin and inferior to that of heparin. High-dose Danshensu's better effect on elevating the platelet counts was superior to low-dose Danshensu and aspirin. Low-dose Danshensu's obvious effect on decreasing D-D levels was close to heparin and superior to high-dose Danshensu and aspirin. High- and low-dose Danshensu's significant effects on reduced thrombin time level are same to heparin. Different anticoagulants all played improvement roles in placental fibrin depositions, but heparin and high-dose Danshensu's roles on lowering thrombomodulin expression in placentas were superior to low-dose Danshensu and aspirin. However, anticoagulant function of high-dose Danshensu was still inferior to heparin. We found long-term use of heparin and aspirin, in spite of low-dose administration, could raise the risk of bleeding such as placental abruption and intestinal hemorrhage. But no any side effect was observed in mice treated with different doses of Danshensu in our study.

CONCLUSIONSDanshensu has proven to be effective and safe in ameliorating the prognosis of maternal syndrome in a preeclampsia mouse model. We suggest long-term provision of low-dose Danshensu in pregnancy, leading to an improvement of preeclampsia syndrome with considerable maternal safety.

OBJECTIVETo study the efficacy and safety of noninvasive ventilation (NV) for treating children with obstructive sleep apnea.

METHODSTwenty-one children confirmed obstructive sleep apnea hypopnea syndrome (OSAHS) with full-night polysomnography (PSG) or ambulatory screening device were enrolled in the study. The NV treatment was carried out successfully for all cases. Nasal continuous positive airway pressure (nCPAP) compliance data were gathered via clinical follow-up examination, telephone interview, or mailed questionnaire. The statistical analysis was performed with SPSS 11.0 statistical software. Pre- and on-nCPAP parameters were compared with paired t-test. Twenty-one OSAHS children (17 boys, 4 girls) were enrolled into the study. The mean age of the children was 4. 5 years; ranging from 40 days to 11 years.

RESULTSnCPAP pressure was increased from 4 cm H2O by (1 cm H2O = 0.098 kPa) 0.2 cm H2O each time to the treating pressure which was between 4.8 and 16 cm H2O. Before nCPAP treatment, apnea hypopnea index (AHI) was (80.8 +/- 45.1)/h, the lowest pulse oxygen saturation (SPO2) 0.557 +/- 0.135 and SPO2 <0.90 time during sleep (42.9 +/- 31.9) %, which were much worse compared to that with nCPAP treatment, the above parameters decreased to (6.7 +/- 12.4)/h, 0.862 +/- 0.082, (1.1 +/- 2.5) % respectively(P <0.01).

CONCLUSIONSNoninvasive ventilation is a safe and effective treatment for OSAHS children. It is possible to use nCPAP as a short-term treatment or as a long-term treatment at home.

OBJECTIVETo study the effect of Jinguo Weikang Capsule [see text] on the gene expression of H-ras, epidermal growth factor receptor (EGFR), P53 and C-myc of the gastric mucosa in rats with gastric precancerous lesions, and to investigate the action mechanism of JWC on gastric precancerous lesions.

METHODSA rat model with paratypical proliferation of the gastric epithelium mucosa was established by using 60Co irradiation. Rats were divided into the normal group, model group, high-, medium-, low-dose JWC treatment groups, and the vitacoenzyme control group, and were treated for 30 days. The expression of H-ras, EGFR, P53 and C-myc genes of the gastric mucosa was detected by using immunohistochemical methods.

RESULTSThe expression and over-expression rates of H-ras, EGFR, P53 and C-myc gene in the high-and medium-dose JWC treatment groups were significantly lower (P<0.05) as compared with those of the model group.

CONCLUSIONJWC can inhibit the expression of the H-ras, EGFR, P53 and C-myc genes expression of the gastric mucosa in rats, which may be one of mechanisms involved in suppressing or reversing gastric carcinogenesis.

OBJECTIVETo assess the co-morbidity of anxiety and depression in hospitalized patients and to analyze the degree of symptoms and the influential factors.

METHODSThirty patients with malignant tumor were injected with thymosin alpha 1 subcutaneously at the dose of 1.6 mg q.d. for the first month and q.o.d. for the following month. The number of T cell subgroups and the activity of NK cell in peripheral blood were detected and the quality of life of the patients were evaluated before treatment and at the end of treatment.

RESULT(1) About 39.9 % of the patients presented the symptoms of anxiety and depression and out of them 6.7 % were taken psychotropic medication. (2) Stepwise Logistic Regression showed that the factors related to anxiety and depression could be classified into four categories: economic factor, sleeping status, cognition of disease, the other factors such as course of disease and the environment of hospital. (3) Data analysis of oncology patients showed that the cognition of disease would be an important factor, which would affect anxiety and depression status.

CONCLUSIONMultiple factors can affect anxiety and depression symptoms of inpatients. The results suggest that psychological intervention such as cognitive therapy should be considered in clinical practice.

OBJECTIVETo examine the differences in the expression of HSP27 and c-kit between benign prostatic hyperplasia (BPH) and prostatic cancer (PCa) tissues and to analyse the relationship between their expression and BPH and PCa, especially the relationship with the occurrence, development, prognosis and treatment of PCa.

METHODSAn immunohistochemical staining (SP method) for HSP27 and c-kit was undertaken on 40 BPH and 40 PCa tissues samples.

RESULTSConsistent patterns of cytoplasmic staining for HSP27 were seen in all sections of tissue from BPH. The glandular epithelium stained very strongly positively and the stroma stained positively. The staining for HSP27 in PCa tissues was located in the cytoplasm of glandular epithelia, but the expression of HSP27 in PCa was higher than BPH (P < 0.05). The staining for c-kit in BPH tissues was located in the cytoplasm of smooth muscle cells, and in PCa tissues was located in epithelial cells. The expression of c-kit in PCa tissues was lower than BPH (P < 0.05). The expression level of both HSP27 and c-kit were decreased with the development of grade of PCa (P < 0.05); HSP27 was increased with the development of clinical stage of PCa (P < 0.05 ); c-kit was decreased with the development of clinical stage of PCa (P < 0.05).

CONCLUSIONThe expression level of HSP27 and c-kit was highly correlated with the process of the development from BPH to PCa, and also correlated with tumor grades and stages. The expression of HSP27 and c-kit may be used as an important pathological index and may be helpful for the treatment of PCa.
