According to TCM theory of the wholistic concept and the principles of syndrome differentiation and treatment, the characteristics of the pathogenesis of aplastic anemia (AA) were summarized and corresponding treatment was put forward on the basis of clinical observation and the study of literature. In the pathogenesis of AA, the deficiency of spleen and kidney is the primary aspect, fire attacking blood vessels is the secondary aspect and there is change because of blood stasis. In treatment, the method of invigorating spleen and tonifying kidney is adopted in order to get at the root, and releasing fire to stop bleeding is adopted in order to bring about a temporary solution, and activating blood circulation to dissipate blood stasis is adopted in order to produce blood. The outline should be caught hold of that consumption is primary aspect and fire is secondary aspect and there is change because of blood stasis in order to obtain satisfactory curative effect.

A mild rapid method for the determination of Pb in grain was established by diluted acid extraction and direct sampling detection with graphite furnace atomic absorption spectrophotometer(GF-AAS). Some factors, such as the grain size, nitric acid concentration, extraction time, solid, liquid proportion, and the instrument conditions were optimized. The results indicated that, at room temperature, the extraction rate of Pb in grain by diluted nitric acid was between 92. 14% and 94. 75%, and the average recoveries of Pb in grain extract reached 91. 65%-94. 58%, the precision of method was less than 5%, and the method detection limits and quantification limits were 0. 64 μg/L and 2. 14 μg/L, respectively, meanwhile, the extraction time was shorten to no more than 30 min. Compared with the results pretreated by microwave digestion and determined by GF-AAS, the detection values obtained by diluted acid extraction had no significance difference (p<0. 1).

OBJECTIVE: To investigate the perioperative treatments of endoscopic sinus surgery for nasal diseases in patients with coronary heart disease after PCI. METHOD: Clinical data of 12 cases of endoscopie-assised surgery such as nasal tumors resection,functional sinus surgery,correction of deviated nasal septum,low-temperature plasma hemostasis in patients with coronary heart disease after PCI were analyzed retrospectively. RESULT: Serious bleeding did not take place with the 12 cases during surgery, and surgery progressed smoothly; one of patients had heavy nosebleed after surgery, however her condition was stable when received active treatment. Follow-up 3 months to 2 years, nasal diseases of 12 patients recovered well and symptoms were relieved; cardiovascular events such as hemorrhage, thrombosis and so on did not occur. CONCLUSION Due to physiological function of the heart dysfunction in patients with coronary heart disease after PCI,they often accompany a number of trouble issues such as medical disorders, oral antiplatelet drugs, surgery affordability loss and increase surgical risk. Correct and effective perioperative treatments, strictly surgical indications are really necessary which can keep patients safe through perioperative period.

Objective To investigate the clinical significance of Doppler flow waveform of ductus venosus (DV) in screening of fetal cardiac malformation.Methods Color Doppler ultrasonography was used to study DV flow in 240 normal fetuses and 20 fetuses with cardiac malformation that were screened out from the high-risk fetuses with congenital heart disease (CHD).Results ① The normal Doppler flow waveform of the DV was a characteristic triphasic pattern with forward flow during cardiac cycle,reflecting ventricular systole (S),ventricular diastole (D) and atrial systole (A).② In the group of 20 fetuses with cardiac malformation,eight had reverse flow and nine had decreased or absent flow during atrial contraction,the indices of the DV in fetuses with cardiac malformation were higher than those in gestational age-matched normal fetuses ( P

OBJECTIVEThis study aims to evaluate the nasolabial angle change and the correlation analysis ot Angle'Is Class II division 1 malocclusion patients with vertical growth pattern after tooth extraction orthodontic treatment and provide experimental results to help in making orthodontic treatment plan and treatments.

METHODSA total of 38 Angle's Class II division 1 malocclusion patients with vertical growth pattern and tooth extraction orthodontic treatment were included in this study. Pre- and post-treatment cephalometric X-rays were performed, and 18 measurement items were measured. The change values of pre- and post-treatment, youngsters, and adults were compared to analyze the correlation of the nasolabial angle change.

RESULTSThe nasolabial angle between youngsters and adults was enlarged after treatment, but the nasolabial angle of the adult group changed more significantly. Ul to FH, Ul to NA, U1-NA, Spr-Ptm were reduced after treatment, and the adult group decreased more significantly. The upper lip sulcus and flange thickness, A'-Ptm, upper lip length, and nose prominence were enlarged after the adolescent treatment, but the adult had a certain degree of decrease. The difference had statistical significance. In the correlation of the nasolabial angle change analysis of the two groups, namely, Ul to FH, Ul-NA and U1 to NA had significant negative correlation, significant positive correlation to the upper lip inclination angle, and more significant correlation in the adult group. Upper lip flange thickness and nasolabial angle were negatively correlated, and the upper lip sulcus thickness was positively correlated. However, no significant correlation was observed between these two in the adult group.

CONCLUSIONThe nasolabial angle change of adolescents with vertical growth pattern in class II division 1 malocclusion after extraction treatment is related to the upper anterior teeth hard tissue and upper lip soft tissue, whereas only adults and upper anterior teeth hard tissue are related.

Objective To evaluate the efficacy and safety of prophylactic cefiazidime on early bacterial infection in APBSCT recipients during neutropenia.Methods APBSCT recipients were prospectively randomly assigned to intravenous ceftazidime treatment group and control group (no prophylaxis of antibiotics).The treatment started from the first day until resolution of neutropenia or the appearance of early bacterial infection.Results From March 2010 to January 2013,70 APBSCT recipients were enrolled in the study with 36 in treatment and 34 in control group.Overall,29 (41.4％) patients developed early bacterial infection,among which,9(25.0％) in the treatment group and 20(58.8％) in the control group (P =0.004).The median infection free survival (IFS) was not reached in the treatment group and was 8 days in the control group (P =0.005).Despite whether patients received single high dose melphalan or other conditioning regimes,the early bacterial infection rate was lower in the treatment group than in the control group,and the median IFS was longer in the treatment group than that in the control group.The mean courses of antibiotic administration were (8.08 ± 2.03) days and (3.68 ± 3.56) days respectively in the treatment and control groups (P ＜ 0.001).However,the duration of empirical carbapenems were (1.67 ±3.03) days and (3.68 ±3.56) days respectively (P =0.013).There was no significant difference of antibiotics cost per patient between the two groups.Four patients in the treatment group had a transient elevated serum creatinine.Overall,no infection related mortality was observed in either group.Conclusions Prophylaxis of intravenous ceftazidime for APBSCT recipients is effective in preventing early bacterial infection with an acceptable toxicity and cost profile.However,it doesn't have effect on infection related mortality.Therefore,our results do not support the use of antibiotic prophylaxis for patients undergoing APBSCT.

Objective To explore the characteristics of hematological changes in patients with primary Sj(o)gren'syndrome (pSS).Methods The clinical data of 49 cases with pSS were retrospectively analyzed.Resuits The data showed that 25 patients (51%) among 49 cases had hematological changes.of which 15 cases were anaemia (31%).8(16%) were leukopenia,and 10 cases (20%) were thrombocytopenia.And 6 cases had two cell lines involved.2 cases had three cell lines involved.Twenty-three bone marrow aspirations revealed active proliferation or normal cell proliferation and the morphology of all 3 cells lines were normal.Bone marrow examination had strong positive iton stain and 15 cases with anaemia showed positive iron stain.Seven out of 10 patients with thrombocytopenia had megakaryocyte maturation defect.Conclusion Hemotologieal changes are common.and anemia is the most common findings.Cytopenia is related to autoantibodies mediated stem cell damages.but anemia iS caused by iron metabolic disturbance.while thrombocytopenia is generally due to functional impairment of megakaryocytes.

Objective To investigate the characteristics in sleep architecture of sub-healthy people with in-somnia,and to study the relationship between the sleep architecture and the degree of insomnia.Methods Sleep ar-chitecmre and Pittsburg sleep quality index(PSQI)value and PSQI scale were detected respectively.Results Sleep architecture of 46 subjects was abnormal-including shortened total-sleep-time(26.1%),excessive superficial-sleep stage(100%).inadequate deep-sleep stage(87.0%),insufficient rapid eye movement sleep(REM) (60.9%),longer sleep latency(65.2%)-more wakening times(47.8%)and longer wakeful time(43.5%).PSQI value of each insomniac exceeded 7,and the valtie of most objects was between 12 and 16(73.9%).The in-gredients of sleep architecture were not significantly correlated with the values of PSQI (P>0.05).Conclusion The sleep architecture of sub-healthy people with insomnia is mainly characterized with difficulty in falling asleep,light sleep and festless sleep,but the characteristics of sleep architecture is not inevitablly related with the degree of insomnia.

Objective To determin and compare the significance of the expression of chemotactic cytokines in pleural effusions monocyte chemoattractant protein-1(MCP-1)and regulated on activation,normal,T-cell expressed and secreted(RANTES)levels in tuberculous and malignant pleural effusions.Methods The effusion and serum levels of MCP-1 and RANTES were measured in 37 patients with tuberculous pleural effusion and 35 patients with malignant pleural effusion,and selected 20 healthy people acting as control group.Results The effusion and serum levds of MCP-1 and RANTES in tuberculous effusion patients was significantly higher than that in malignant group(P＜0.01);In tuberculous group,the content of MCP-1 in serum was higher than control group,the serum level of RANTES was no statistic significant difference between control group and tuberculous group.The contents of MCP-1 and RANTES were not correlated with pathologic type of lung.cancer.Conclusion MCP-1 and RANTES technique has an important clinical value in diagnosis and differential diagnosis of tuberculosis and malignant pleural effusion.
