BACKGROUND: Femoral head necrosis can be induced in adult rabbits when a large dose of steroid has been used for a long time. However, the pathogenesis of steroid-induced femoral head necrosis needs further study.OBJECTIVE: To probe into the mechanism of the disease by light microscope and transmission microscope from morphological perspective based on the model of femoral head necrosis in rabbits.DESIGN: A randomized controlled observation.SETTING: Laboratory of Morphology; Teaching and Research Division of Pathology; Laboratory of Surgery, Weifang Medical College.MATERIALS: The experiment was carried out at the Experimental Center of Morphology, Weifang Medical College, between March 2002 and March 2003. Totally 40 adult New Zealand white rabbits were randomly divided into control group (n=10), dexamethasone group (n=10) and horse serum group (n=20).METHODS: Control group was given intravenous injection of normal saline of 10 mL/(kg·d) for 7 consecutive days. Dexamethasone group was given intramuscular injection of dexamethasone of 10 mL/(kg ·d)for 7consecutive days. Horse serum group was given intravenous administration of horse serum of 10 mL/kg; 3 weeks later the same volume of horse serum was injected once again, followed intramuscular injection of dexamethasone of 10 mL/(kg·d)for 7 consecutive days. Inferior sections of cartilage of the femoral head necrosis in the experimental animals were obtained 5 and 10weeks later, and then histological and ultrastructural changes were observed under the light microscope and transmission microscope.MAIN OUTCOME MEASURES: ① Histo-morphological observation of the animals in each group. ② Ultrastructural changes.RESULTS: All the experimental animals survived and entered the result analysis. ① Histo-morphological observation: The cells of inferior sections of cartilage of the femoral head necrosis of the experimental animals in control group were arranged regularly and had a small volume of elliptical bone cells. The cell body was located at bone lacuna, blood vessel arranged well in the medullary cavity of bone. Lesion haracteristics of femoral head in dexamethasone group and horse serum group were similar:Hematopoietic adipose in the medullary cavity of bone was significantly decreased while fat adipose obviously increased; bone trabecula of metaphysis and the inferior sections of cartilage of femoral head were found with ered, and so was the bone nucleus. The number of lacuna of bone was increased. ② Ultrastructural changes: Normal bone cells in control group were elliptical, located at bone lacuna. Nucleus was at one end of the cell with complete karyotheca and many mitochondria in the cytoplasm. In dexamethasone group and horse serum group there were lipid droplets in the osteocytes, narrowed blood capillary in the medullary cavity of bone and injured vascular endothelial cells.CONCLUSION: Corticotropin can induce necrosis of femoral head; the hormone causes accumulated fat adipose in the medullary cavity of bone.The increased internal pressure in the medullary cavity leads to ischemia of femoral head, thus inducing the necrosis of osteocytes.

Objective To observe the therapeutic effect of Qilin Xintongshu pill for treatment of patients with non-ST segment elevation acute coronary syndromes(NSTE-ACS)accompanied by gastrointestinal bleeding (GIB). Methods A prospective randomized controlled trial was conducted. A total of 67 hospitalized patients in Cardiovascular Department of Qionghai City Hospital of Traditional Chinese Medicine were divided into therapy group(35 cases)and control group(32 cases). Both groups were given conventional medical treatment(except anti-coagulative agent). In the therapy group,the patients received Qilin Xintongshu pill(the ingredients consisting of panax pseudo-ginsen,dragon's blood,immature orange fruit,etc.)oral administration,once 5 mg and 3 times a day,while in the control group,the patients accepted clopidogrel orally,once 75 g and once a day,the therapeutic course in both groups being 30 days. The major cardiovascular events(such as death,a newly-happened myocardial infarction(MI),MI secondary,obstinately ischemia)and incidence of massive hemorrhage of gastrointestinal tract were compared between the two groups,and the adverse events were observed. Results After treatment,the incidence of cardiovascular events and massive hemorrhage of gastrointestinal tract in the therapy group were decreased significantly compared to those in the control group 〔incidence of cardiovascular events:8.57%(3/35)vs. 28.13%(9/32), incidence of massive hemorrhage of gastrointestinal tract:2.86%(1/35)vs. 21.88%(7/32),both P<0.05〕. Adverse events were not observed in both groups,and the examinations of blood,urine,liver and renal functions were of no abnormalities before and after treatment. Conclusion Qilin Xintongshu pill can effectively reduce the incidences of cardiovascular events and massive hemorrhage of gastrointestinal tract in patients with NSTE-ACS accompanied by GIB in the therapeutic course of 30 days,therefore this traditional Chinese herbal medicine is an ideal agent for treatment of such disease.

Objective To investigate Monilia infection and adverse pregnancy outcomes of pregnant women in labor.Methods Before informed consent,542 cases of pregnant women in labor were collected in Obstetrics Department of Maternity and Child Healthcare of Maoming City from January 2013 to April 2014,and all of these cases were examined by Monilia inspec-tion of vaginal secretions.All of these cases were 20 to 30 years old,without vaginal pathogenic infection symptoms,but in-cluded in a few of formulation of clinical features of vaginal Candida infection.With the two methods of 10% potassium hy-droxide solution wet sheet and Gram staining,if blastospore or pseudohypha of Candida mycoderma were found out in the two methods under microscope,this case was diagnosed as positive result,otherwise as negative result.Respectively choosing positive cases as observation group,and negative cases as control group,the indexes of premature rupture of membranes,per-ineum wound infection,neonatal thrush and neonatal diaper rash of the two groups were recorded.The statistical method:e-numeration data by chi-square test,measurement data using analysis of varianc.Results The positive rate of Monilia was 23.1% (125/542),higher than 19.3% reported in domestic.The incidence rates of neonatal diaper rash,premature rupture of membranes,neonatal thrush and perineum wound infection of the observation group were respectively 19.2%,8.0%, 16.8% and 12.8%,all much higher than the control group respectively was 8.4%,1.2%,3.8% and 1.7%,(χ2 =12.578~29.273,all P <0.01).Conclusion Monilia infection of pregnant women in labor could increase the chance of adverse preg-nancy outcomes.Healthy or clinical doctors should suggest that pregnant women early carry out routine examination and ear-ly treatment,in order to prevent adverse pregnancy outcomes.

Objective To evaluate the clinical efficacy of Qilinxintongshu pill for treatment of critical patients with unstable angina pectoris (UAP) accompanied by upper alimentary tract damage.Methods A prospective randomized controlled trial was conducted. A total of 60 critical outpatients or inpatients with confirmed diagnosis of UAP accompanied by upper alimentary tract damage in Cardiology Department of Hospital of Traditional Chinese Medicine of Qionghai City from November 2011 to January 2015 were enrolled in the study, and they were assigned to a therapy group (30 cases) and a control group (30 cases) by table of random number. The conventional medical basic therapy was given to both groups, in addition, the patients in therapy group took Qilinxintongshu pill (made of notoginseng, dragon's blood, fruit of immature citron, etc.) 5 g once, three times a day, and the patients in control group orally administered clopidogrel 75 mg once a day, the therapeutic course being consecutive 30 days. After treatment, the rates of main cardiovascular events [including death, a newly-happened myocardial infarction (MI), and obstinate ischemia] and events of alimentary damage were compared between the two groups, and adverse effects were observed.Results There was no statistically significant difference in incidence of cardiovascular events between the therapy group and control group [6.7% (2/30) vs. 16.7% (5/30),P > 0.05]. The incidence of massive hemorrhage of gastrointestinal tract was significantly lower in therapy group than that in control group [10.0% (3/30) vs. 36.7% (11/30),P < 0.05]. In the treatment process, there was no significant untoward side effect, and no abnormalities in routine blood and urine tests, liver and renal functions were found.Conclusion Qilinxintongshu pill for treatment of critical patients with UAP accompanied by upper alimentary damage is safe and effective, and does not enhance the incidence of massive hemorrhage of gastrointestinal tract.

Objective To study the correlation of PAZ with anti-tuberculosis treatment regimen and drug-induced liver injury in tuberculosis patients with HBV-DNA positive in order to provide an optimized treatment regimen. Methods from Jan 2013 to Dec 2014, 199 pulmonary tuberculosis with HBV-DNA positive patients and 103 pulmonary tuberculosis patients without HBV in our hospital were collected. They were assigned as follows:122 cases were anti tuberculosis treatment with antiviral therapy,64 cases were A(HRZE),58 cases were B (HRE). 77 cases were anti tuberculosis treatment but not antiviral therapy , 41 cases were C (HRZE), 36 cases were D(HRE) and 103 patients without HBV were E (HRZE, the contrast group). We had observed the liver injury for 2 months after the treatment. Results 1.Incidence of liver injury was 34.38% in group A , higher than the cases in group B(20.69%,P > 0.05). 2.Incidence of liver injury in group C was apparently higher than in group D (73.17% vs. 30.56%,P < 0.05). 3.Incidence of liver injury in group B was lower than group D (20.69% vs. 30.56%,P > 0.05)4.Incidence of liver injury in group A was lower than group C (34.38% vs. 73.17%,P < 0.05).5. Incidence of liver injury in group A was higher than group E (34.38% vs. 17.48%,P< 0.05)and there was no difference between group B and group E (20.69% vs. 17.48%,P> 0.05). Conclusion Although anti tuberculosis treatment combined with antiviral therapy can be partially reduce the incidence of liver injury and relieve the severity of liver injury in tuberculosis patients infected with HBV , but PZA toxicity to hepatocytes is a major risk factor for liver injury , and we need to change the treatment plan to reduce the occurrence of liver injury.
