OBJECTIVE:To optimize the extraction technology of total volatile oil from Cinnamomum cassia Presl. and Cyper-us rotundus L. in Hegan lipi granules. METHODS:With the extraction rate of total volatile oil as the index,Box-Behnken response surface method was applied to investigate the effects of water amount,soaking time for medicinal materials and extraction time by distillation on the amount of the extracted volatile oil and optimize the extraction technology of total volatile oil from C. cassia Pre-sl. and C. rotundus L. in Hegan lipi granules,and verification tests were conducted. RESULTS:The relevant coefficient of the es-tablished quadratic polynomial regression model of 3 variable factors was 0.970 5. The optimal extraction technology was as follows as 5 times as much as the amount of medicinal materials of water,soaking time of 2.5 h,extraction time of 6.0 h. Verification tests showed the extraction rate of total volatile oil was 1.65%,with a deviation rate lower than 2% compared to the predicted value of 1.67%. CONCLUSIONS:The established model is reliable with good predictability. The optimal technology can be used for the ex-traction of total volatile oil from C. cassia Presl. and C. rotundus L. in Hegan lipi granules.

Objective To analyze the current status and influencing factors of job competence of clinical nursing teachers. Methods A total of 673 clinical nursing teachers from 35 second-level and above hospitals in Anhui Province were selected as research subjects using convenient sampling method. Their job competence was evaluated using the Clinical Nursing Teacher Post Competency Evaluation Scale. Results The score of job competence of clinical nursing teachers was 87.1±9.7. The results of multiple linear regression analysis showed that with the increase of service length and clinical teaching years，the job competence score of clinical nursing teachers increased（all P<0.05）. For those who thought the higher the satisfaction with the teaching atmosphere of the hospital，the hospital teaching training can meet their requirements and the higher the willingness to accept the teaching training，the higher their job competence score（all P<0.05）. Conclusion There is still much room for improvement in job competence of clinical nursing teachers in Anhui Province. The length of service，clinical teaching years， hospital teaching atmosphere，teaching training meeting demand，and willingness to accept clinical teaching training are the influencing factors of job competence of clinical nursing teachers.

Objective To study improvement of cognitive function impairment of vascular dementia rats induced by a permanent bilateral ligation of common carotid arteries (2VO) after administration of leptin in brain. Methods Hippocampal neurons was isolated and cultured from SD rats. At oxygen-glucose deprivation condition, protection role of leptin on hippocampal neurons was observed and expression of leptin receptor was detected. Animal model of rats was established by 2VO. Pre-treatment VaD model of leptin was established by administration leptin into hippocampus region. The Morris water test was performed to detect difference in the cognitive function between VaD group and control group. Neuron apoptosis in hippocampus tissue were determined with TUNEL. Results Leptin receptor expression could be seen in hippocampal neurons. After oxygen-glucose deprivation cultured for 12 h , plenty of apoptotic cells were seen in hippocampal neurons, apoptosis rat was up to (72.96 ± 6.25) % , while apoptosis rate was (46.33 ±7.85)% and (23.58 ±5.08)% in 1 ( μg and 5μg leptin treatment group,respectively. Compared leptin treatment group with control group,difference had a statistical significance(P<0.01). Compared with untreated VaD group, latency time was shorter and average velocity was increased in leptin-treat-ment VaD group. Neuron apoptosis in hippocampus tissue of leptin-treated group were different significantly from those of untreated group (P < 0.01). Conclusion Leptin could protect hippocampal neurons from apoptosis in vitro. Cognitive function impairment could be improved by administration of leptin into brain in VaD rats.

Objective To investigate the characteristic and diagnosis of left ventricular diverticulum. Meth-ods As one left ventricular diverticulum patient was diagnosed by echocardiography in our hospital,we reviewed and analyzed about published in China. Results Left ventricular diverticulum is a rare disease of congenital heart malfor-marion, Echocardiographic characteristics of the left ventricular diverticulum is the saccular evngination of the left ven-tricular wall with the neck of the diverticula being smaller than the body. Left ventricular diverticulum is classified into contractile muscular type and fibrous type ,The saccular wall of contractile muscular diverticulum remain a normal mo-tion and is thinner than the normal wall The saccular wall of the fibrous diverticulum is due to a loss of myocardial thickness, as thin as aneurysm with a dyskinetic motion. Conclusion Left ventricular diverticulum is a rare disease in clinic, echocardiography is very important for diagnosing classifying.

Aim ToinvestigatetheeffectsofCa2+/calmodulin-dependent protein kinase Ⅱ inhibitor KN-93 on calcium overload-induced heart injury.Methods Thirty-twoisolatedratheartswererandomlydivided into the control group,KN-93 control group,calcium paradox group,and calcium paradox with KN-93 treat-ment group.Left ventricular pressure were recorded, and the heart function was evaluated by the left ventric-ular end-diastolic pressure (LVEDP ) and developed pressure (LVDP).Coronary flow (CF)were collect-ed,and lactate dehydrogenase (LDH)content was de-termined.Triphenyltetrazolium chloride staining was usedtomeasuretheinfarctsize.Results Compared with the control group,KN-93 at 2. 5 μmol·L-1 had no effects on coronary flow,cardiac performance and cell death at the end of perfusion in normal rats (P>0. 05 );The hearts of calcium paradox exhibited a de-crease in LVDP and CF,meanwhile an increase in LV-EDP,LDH,and infarct size of 18 ±7. 2% (P <0. 01).2. 5 μmol·L-1 KN-93 further increased the levels of LVEDP,LDH and infarct size (P<0. 01)in Ca2+paradoxical hearts,while it provoked the decline intheCFandLVDP(P<0.01).Conclusion The data demonstrates that KN-93 aggravates heart injury in calcium paradox,it also suggests that CaMKⅡ is in-volved in the Ca2+overload-induced heart injury.

Objective To evaluate the diagnostic value of quantitative detection of cytomegalovirus (CMV) DNA from different sources [plasma, sputum and bronchoalveolar lavage fluid(BALF)] for CMV pneumonia after allogeneic hematopoietic stem cell transplantation. Methods Clinical data of 405 recipients undergoing allogeneic hematopoietic stem cell transplantation were retrospectively analyzed. Among them, 19 recipients diagnosed with CMV pneumonia were assigned into the CMV pneumonia group, and 229 recipients with CMV viremia alone, 11 recipients without CMV pneumonia who received fiberoptic bronchoscopy and 16 recipients diagnosed with bacterial or fungal pneumonia based on pathogenic evidence receiving sputum culture were assigned into the control A, B and C groups, respectively. The incidence of CMV pneumonia was summarized. The CMV DNA load of specimens from different sources (plasma, sputum and BALF) of recipients with CMV pneumonia was analyzed. The clinical prognosis of recipients with CMV pneumonia was evaluated. Results Among 405 recipients undergoing allogeneic hematopoietic stem cell transplantation, 19 cases developed CMV pneumonia, and the overall incidence of CMV pneumonia was 4.7%(19/405). The CMV DNA load in the plasma, sputum and BALF of recipients with CMV pneumonia was higher than those in the control A, B and C groups (all P < 0.05). In the 19 recipients, 12 cases were cured after antiviral treatment and 7 died from treatment failure(3 cases abandoned treatment). The fatality was 37%(7/19). Conclusions Quantitative detection of CMV DNA in the plasma, sputum and BALF may increase the diagnostic rate of CMV pneumonia, thereby improving clinical prognosis of recipients undergoing allogeneic hematopoietic stem cell transplantation.

Objective: To investigate the efficacy of allogeneic hematopoietic stem cell transplantation (allo-HSCT) in the treatment of leukemia patients also suffering from central nervous system leukemia (CNSL) . Methods: A total of 48 leukemia patients with central nervous system leukemia admitted to our hospital from May 2012 to December 2017 were retrospectively analyzed. Results: ① Including 22 cases of acute lymphocytic leukemia (ALL) , 21 cases of acute myeloid leukemia (AML) , and 5 cases of chronic myelogenous leukemia (CML) . Before transplantation, 19 patients achieved complete remission (CR) , and the rest 29 ones without remission. ②The conditioning regimen used TBI as the main protocol, and 6 patients were combined with whole brain and total spinal cord radiotherapy, 2 with Cyber knife treatment, and children with modified IDA combined with BUCY. ③All 48 patients were successfully transplanted, the median time for leukocyte engraftment was 14 (10-23) days, the median time for platelet transplant 16 (6-78) days. ④Bone marrow was evaluated 28 days after transplantation, all 48 patients reached CR, and DNA testing confirmed that they were all full donor chimerism. ⑤The median follow-up was 14 (2-69) months. Of them, 28 cases survived, 10 relapsed and the rest 3 had recurrence of CNSL after transplantation. One year after allo-HSCT, the overall survival (OS) of CR and non-CR groups were (77.3±10.0) % and (57.6±9.3) % (P=0.409) , respectively, the disease-free survival rates (DFS) were (71.2±11.0) % and (53.9±9.5) % (P=0.386) , respectively. The 1-year OS rates of ALL and AML groups after transplantation were (54.2±10.7) %, (80.1±8.9) %, respectively (P=0.200) , and DFS rates were (49.2±10.8) %, (75.0±9.7) % (P=0.190) , respectively. Conclusion Allo-HSCT was safe and effective for leukemia patients with CNSL.
