Objective To explore clinical treatment of postoperative hyponatremia of pituitary tumor. Meth-ods 32 cases of patients with postoperative hyponatremia of pituitary tumor were randomly divided into control group and treatment group. The control group(n = 15) was treated with routine western medicine, and the treatment group(n = 17) was treated with water limited and sodium supplemented based on the control group. The clinical effect was observed between control group and treatment group. Results The clinical effect in the treatment group was signifi-cantly higher than that of the control group(P <0.05). Conclusion The treatment of water limited and sodium sup-plemented on postoperative hyponatremia of pituitary tumor is better.

Objective To observe clinical effects of treating subarachnoid hemorrhage with intracranial aneurysm interventional embolization combined with Chinese herbs of removing blood stasis and hemostasis. Methods 45 cases with subarachnoid hemorrhage were randomly reeurited into a control group and a treatment group. The control group was treated with intracranial aneurysm interventional embolization, and the treatment group was treated with intracranial aneurysm interventional embolization combined with Chinese herbs with the functions of removing blood stasis and hemostasis. The clinical effect was observed between the groups. Results The clinical effect in the treatment group was significantly higher than that of the control group (P< 0.05 ). Conclusion The treatment of subarachnoid hemorrhage with intracranial aneurysm interventional embolization combined with Chinese herbs of removing blood stasis and hemostasis is better than intracranial aneurysm interventional embolization exclusively.

BACKGROUND:Cryopreservation of human umbilical cord mesenchymal stem cel s has been a hot research issue currently, but the studies concerning their effects on expansion of hematopoietic stem/progenitor cel s after cryopreservation are seldom. OBJECTIVE:To investigate the effects of human umbilical cord mesenchymal stem cel s before and after cryopreservation as feeder layer on expansion of human bone marrow mononuclear cel s in vitro. METHODS:2.5g/L mitomycin C processed human umbilical cord mesenchymal stem cel s and bone marrow mesenchymal stem cel s at passage 3 were used as the feeder layer to expand adult al ogeneic bone marrow mononuclear cel s in culture. Up to day 35, methylcel ulose assay was used to detect hematopoietic stem/progenitor cel colony proliferation. RESULTS AND CONCLUSION:There were no differences in the morphology and size of colonies in the cryopreserved human umbilical cord mesenchymal stem cel group, bone marrow mesenchymal stem cel group and non-cryopreserved human umbilical cord mesenchymal stem cel group. However, these parameter described above were significantly higher in these three groups than the blank control group (P<0.05). There were fewer colonies in the cryopreserved human umbilical cord mesenchymal stem cel group than the non-cryopreserved human umbilical cord mesenchymal stem cel group (P<0.05). These findings indicate that human umbilical cord mesenchymal stem cel s before and after cryopreservation have the ability as feeder layer on expansion of bone marrow mononuclear cel s in vitro similar to bone marrow mesenchymal stem cel s. But this ability of human umbilical cord mesenchymal stem cel s may decrease after cryopreservation.

BACKGROUND: Endothelin and nitrogen monoxide (NO) which are regarded as a pair of factors to maintain equilibrium between vascular stress and hemodynamics have different responses during various diseases. It is the key point for the treatment of atherosclerosis to find out the effect and pathophysiological mechanism of hyperlipemia on endothelial cells, and seek the methods and drugs for protecting vascular endothelin.OBJECTIVE: To observe the effect of herbal cake-separated moxibustion on contents of plasma endothelin and NO and analyze its regulative mechanism.DESIGN: Randomized controlled animal study.SETTING: College of Acupuncture and Moxibustion, Hunan University of Traditional Chinese Medicine.MATERIALS: A total of 60 healthy New Zealand white rabbits weighing 1.5-2.5 kg of both genders were selected in this study. Herbal cake was made of danshen, shanzha, yujin, dahuang and zexie, which were crushed into powder according to a certain ratio. Then, vinegar was added to make paste which was 5-8 mm in diameter and 2-3 mm in depth. Moxa cone:(Shenjiu 300) was provided by Suzhou Dongfang Airong Factory (type:Dongfang I; batch number: 20021212).METHODS: The experiment was carried out in the Experimental Animal Center of Hunan University of Traditional Chinese Medicine between November 2003 and October 2004. All rabbits were randomly divided into 4 groups: blank control group, hyperlipemia model group, direct moxibustion group and herbal cake-separated moxibustion group with 15 in each group. Except blank control group, rabbits in other three groups were fed with high fat forage to establish hyperlipemia models. Two groups of acupoints were acupunctured alternatively: Group Ⅰ: Juque (CV14), Tianshu (ST25) at bilateral sides, and Fenglong (ST 40) at bilateral sides; Group Ⅱ:Xinshu(BL15),Ganshu(BL18) and Pishu(BL20), at bilateral sides respectively.On the first day, moxa cone was directly adherent to acupoints of rabbits in direct moxibustion group and lighten for acupuncture, but in herbal cakeseparated moxibustion group, moxa cone which was gotten rid of the carriage was adherent to herbal cake which was put on acupoints and lighted for acupuncture. Each acupoint was acupunctured for 4 successive dosages for once a day. On the next day, the other group of acupoints was acupunctured.The course was 40 days. Rabbits in other two groups were not treated with any ways. On the 41st day, contents of plasma endothelin and NO were measured in each group with radio-immunity method and nitrate-reductase reduction method, respectively.MAIN OUTCOME MEASURES: Contents of plasma endothelin and NO of rabbits after 40-day treatment.RESULTS: Five rabbits died because of diarrhoea or other reasons, including 2 in blank control group, 1 in model group, 1 in direct moxibustion group and 1 in herbal cake-separated moxibustion group. Therefore, 55 rabbits were involved in the final analysis. ① Content of plasma endothelin was lower in herbal cake-separated moxibustion group than that in model group [(431.57±63.68), (500.14±75.41) ng/L, P ＜ 0.05], but there was no significant difference between herbal cake-separated moxibustion group and direct moxibustion group [(431.57±63.68), (429.08±77.07) ng/L, P ＞ 0.05]. ② On NO content, there was an increasing tendency of model group ＜ blank group ＜ herbal cake-separated moxibustion group ＜ direct moxibustion, but there was no significant difference between any two groups [(27.17±16.55),(29.39±13.24), (30.24±20.25), (30.47±19.62) μmol/L, P ＞ 0.05].CONCLUSION: Effects of both two methods of moxibustion in the rabbits with hyperlipemia on content of endothelin are significant and similar, but there are no significant effects on NO content.

Objective To research the thickness of adults frontal bones in many parts and analyze the mean-ing. Methods We chose 130 dry skulls of the Chinese people including 70 male skulls and 60 female skulls and ver-tically devided the frontal bones according the devidement of the superciliary arch into 4 parts on average. Then we measured the thickness of the frontal squama,the frontal tuber,the forehead and temple,the superciliary arch,the or-bital surface and the frontal sinus using the ruler, vernier caliper and protractor. Results We got the thickness of the frontal squama,the frontal tuber,the forehead and temple,the superciliary arch,the orbital surface and the frontal si-nus and calculated the average datas. What's more,besides the thickness of the frontal tuber,forehead and temple,the superciliary arch had statistical significance(P < 0.05) between males and females, other parts of the frontal bones had no statistical significance(P>0. 05). Conclusion We measured the thickness of the frontal squama,the frontal tu-ber,the forehead and temple,the superciliary arch,the orbital surface and the frontal sinus and the datas will had good guiding roles to our department's work.

Objective To investigate the clinical features of aortic dissection (AD) and emergency treatments. Methods Data from 784 patients with aortic dissection were collected in the Department of Emergency from January 2000 through December 2009. A retrospective analysis was carried out to determine the survival rate, mortality rate and treatment efficiency. Results Pain was the most common onset symptom (77.7% , 609/784). The majority of patients (86.5%) had essential hypertension (678/784). All the patients with preoperative diagnosis of aortic dissection underwent emergency medical intervention by internists resulting in 81.5% survival rate (639/784) and 18.5% mortality rate (145/784). There were 157 patients without improvement (20.0% ) and the total efficiency rate was (83. 1% ). The efficiency rate of conventional treatment was 76.4% , while the efficiency rate of triple four-procedure treatment was 89. 8% (P<0.05). Of them, 139 patients (17. 7% ) died in the hospital. Among them,. 26 patients died within 24 hours (18.4% ) and 47 cases died within 48 hours (33. 8% ) and 66 patients died within 72 hours (47.2% ). There were 92 patients who refused treatments after diagnosis, and among them, 81 patients died within 72 hours (88.04% ). The difference in mortality rate between two groups was significant (P<0.05). Conclusions The diagnosis of aortic dissection depends on detailed history, physical examination and CT or MRI imaging. Analgesia, sedation and control of blood pressure are essential for emergency treatments. Early diagnosis and effective emergency treatments are the critical strategy for the early surgical intervention and time window for further treatment to improve the survival rate of AD.
