OBJECTIVETo study the effect of panax notoginseng saponins (PNS) in treating hemorrhagic apoplexy at super-early stage in rats.

METHODSRat model of hypertension with cerebral hemorrhage was induced by collagenase method. Sixty rats were randomly divided into 5 groups: the sham operated group, model group, PNS high, middle, and low dose group, 12 in each; 4 h after modeling, PNS or normal saline was intraperitoneally injected into the rats every 12 h, the total is 5 times. Contents of water, sodium and potassium ion in brain, and the diameter of hematoma in rats of different groups were measured 24 h and 72 h after modeling.

RESULTSCompared with the model rats, nerve defect symptoms aggravated, the contents of water and sodium ion in ipsilateral cortex and basal ganglia were significantly higher, the content of potassium ion was lower and the hematoma diameter was obviously less in the PNS-treated rats (all P < 0.05).

CONCLUSIONPNS may worsen the brain edema and increase the nerve defect score when it was applied at the early stage of cerebral hemorrhage, but could promote the absorption of hematoma, indicating PNS should be used cautiously in treating patients with large amount of cerebral hemorrhage at super-early stage.

Objective:To explore feature of clinic and coronary angiography (CAG)of acute myocardial infarction (AMI)for young adults less than 30 years old.Methods:A total of 41 AMI patients,who were under 30 years old and hospitalzed in our hospital from 2004 to 2012,were enrolled as young group.Another 360 AMI patients >50 years were randomly selected as middle-aged group during the same time.Clinical features and CAG results were compared between two groups.Results:Compared with middle-aged group,there were significant rise in percenta-ges of male (68.1% vs.97.6%),smokers (50.6% vs.80.5%)and hypercholesterolemia (59.2% vs.65.9%)and body mass index [(22.3±6.6)kg/m2 vs.(26.3±9.6)kg/m2 ],and significant reduction in percentages of hyper-tension (63.1% vs.24.4%)and diabetes mellitus (30.6% vs.4.9%)in young group,P<0.05 or <0.01;for ex-citing cause,percentages of psychological factors such as tension and anxiety (29.3% vs.3.6%),staying up late (39.0% vs.2.8%)and heavy drinking (14.6% vs.4.7%)in young group were significantly higher than those of middle-aged group,while percentages of agitation (8.3% vs.0)in middle-aged group was significantly higher than that of young group (P<0.05 or <0.01).For CAG results,young group was mainly single vessel coronary disease (56.1%),which were mainly type A (53.7%)and type B1 (29.3%)lesions,while middle-aged group was mainly multi-vessel coronary disease (48.1%),which were mainly type B2 (29.7%)and type C (33.9%)lesions,and there were significant difference between two groups (P<0.05 or <0.01).Conclusion:Smoking,obesity and hy-perlipidemia are the most important risk factors for acute myocardial infarction;the major exciting causes are sta-ying up late,alcohol drinking and high mental stress etc.in young AMI patients;their coronary lesions are mainly single vessel coronary disease,and of type A and type B1 .

Objective To investigate the effect of 6 % hydroxyethyl starch (HES) 200/0.5 infusion before operation on postoperative immne function in patients. Methods Forty ASA Ⅰ or Ⅱ patients of both sexes aged 21-58 yr weighing 47-79 kg were randomly divided into 2 groups ( n = 20 each): 6% HES 200/0.5 group (group H) and compound sodium acetate group (group A). 6% HES 200/0.5 10 ml/kg or compound sodium acetate solution was infused intravenously over 15 min before anesthesia induction. Anesthesia was induced with iv injection of propofol, fentanyl and vecuronium and maintained with target-controlled infusion of propofol and infusion of remifentanil. Venous blood samples were collected before operation and at 1 h, 1 day and 3 days after operation to detect the serum concentrations of IL-6, IL-8, TNF-α, IL-2, IL-10, IgG, IgA andIgM. Results Serum concentrations of IL-6, IL-8, TNF-α, II-2 and IL-10 were significantly higher after operation in the two groups, and serum concentrations of IgA and IgG were significantly lower after operation in group A than those before operation ( P ＜ 0.05 or 0.01 ). Serum concentrations of IL-6, IL-8 and TNF-α were significantly lower, while serum concentrations of IL-2, IL-10, IgA and IgG were significantly higher after operation in group H than in group A ( P ＜0.05). Conclusion Preoperative infusion with 6% HES 200/0.5 can improve the immune function after operation in patients.

Objective To evaluate the diagnostic value of CT and MRI in tubo ovarian masses. Methods CT scan was performed in 67 patients with tubo ovarian masses confirmed by pathology. 19 of them underwent MRI. Results (1) 20 primary malignant ovarian tumors showed cystic, solid or cystic solid masses; papillary projections on cystic wall; pelvic organs and pelvic wall invasion. Chocolate cysts with malignant degene ration exhibited small nodules on thickened cystic wall on CT and MRI.T 1WI was better for revealing the lesions. (2) Of 11 cases of metastasis to tubo ovary, 4 showed peritoneal linear enhancement. (3) There were 9 cystadenomas and 2 adenofibromas , one of the cystadenomas contained fat, two adenofibromas were similar to uterus in density on CT while showing lower signal intensity on MRI (both T 1WI and T 2WI). (4) Three cases of thecoma exhibited cystic or solid masses, solid thecomas revealed granular enhancement.(5) Teratomas were most spicific, one of them was associated with thecoma.(6) Tubo ovarian abscesses and tuberculosis depicted cystic or cystic solid masses.(7) Two cases of tubal pregnancy showed inhomogeneous soft tissue masses, the lower density areas in the centers were clot and organized tissues confirmed by pathology. Conclusion (1) CT and MRI had higher sensitivity but lower specificity for tubo ovarian masses, the diagnosis should be combined with clinical history and patients′ age. (2) Tumors of two different types may coexist and sometimes fat may be present in tumors other than teratoma.

Objective To investigate if isoflurane preconditioning induces ischemic tolerance against neuronal damage produced by middle cerebral artery occlusion (MCAO) in rats Methods Thirty male SD rats weighing 350 400g were randomly divided into three groups: control group (no pretreatment,n=10),isoflurane preconditioning group (ISO group) (inhalation of 2% isoflurane and 98% O 2 1h per day lasting 5d,n=10), oxygen preconditioning group (O 2 group) (inhalation of 98% O 2 1h per day lasting 5d ,n=10) Right MCAO was induced by a 3 0 nylon thread with round tip inserted cranially into right internal carotid artery under isoflurane anesthesia and maintained for 120 min The neurologic deficit score (NDS) was evaluated 1, 3, 6, 12, 16 and 24h after reperfusion and the infarct volume was calculated at 24th following reperfusion Results The NDS of ISO group was lower than that of other two groups at each time interval (P0 05) Conclusions Isoflurane pretreatment can induce ischemic tolerance against neuronal damage produced by transient MCAO in rats

Objective To evaluate the effects of Botulinum-A toxin (BTX-A) injection into detrusor to treat detrusor hyperreflexia and neurogenic incontinence in the patients with spinal cord injury (SCI). Methods A total of 31 patients with SCI(mean age,30 years;male 20,female 11) were included into the study.All the patients underwent urodynamic examination and voiding diary was recorded.300 U of BTX-A was dissolved in 15 ml of saline,and the solution of BTX-A was injected into 30 different points in detrusor using a flexible cystoscopic needle.The evaluation for the effects and follow-up included voiding diary,urodynamic testing and observation of adverse and toxic effects. Results After the first injection,29 of the 31 patients had symptom relief within 3 to 14 days;4 cases received the second injection;4 cases were treated in combination with anticholinergic medication;and 2 cases had no improvement and,therefore,received other treatments.The mean follow-up was 8.5 months. After 3-week treatment of BTX-A,the mean frequency of incontinence decreased from 14.2 to 2.5 times per day.The mean volume of intermittent catheterization (IC) increased from 124 to 495 ml each time.Urodynamic data showed that mean cystometric bladder storage volume increased from 133 to 475 ml,mean maximum storage detrusor pressure decreased from 62.7 to 17.1 cmH 2O(1 cmH 2O=0.098 kPa).No adverse and toxic effect was observed. Conclusions Our initial experience suggests that Botulinum-A toxin injection into detrusor to treat detrusor hyperreflexia and neurogenic incontinence in patients with SCI may be an effective,safe,feasible and micro-invasive treatment choice.However,it is necessary to observe its long term outcome.
