Objective To explore the features of patients with acute leukemia (AL) in Hematology Department of Shenzhen Hospital affliated to Beijing University during the past six years. Methods The data of the 1056 acute leukemia dignosed in our department between 2002-2007 were collected and analyzed retrospectively. Results The male patients was predominant (male/female ratio was 1.78). The number of patients with acute myeloid leukemia(AML) was higher than that of patients with acute lymphoblastic leukemia (ALL) (AML/ALL ratio was 1.85). Most of the AML patients were young adult (65 %) and elderly ALL patients were very rare(1.33 %). AL cases were tended to increase gradually by year. The ratio of treatment-related AL in Shenzhen was lower than that reported literature in other countries. The major cause of the treatment-related AL were chemotherapy/radiotherapy and psoriasis treated with bimolane. Conclusion Some of the features of AL patients in China were further confirmed and some new features were also found in this study. These changes should be demonstrated by the next national epidemiology survey of leukemia.

OBJECTIVETo evaluate the effectiveness of laser in situ keratomileusis (LASIK) for myopia after 2 year follow-up.

METHODSLASIK surgery was performed for 95 eyes (49 cases) with refractive dioptres (from -1.00 to -16.50 D), and then followed up for more than 2 years. The preoperative spherical equivalent was -1.00(-)-16.50 (-6.73 +/- 2.02) D. Patients were divided into two groups including group I with mild to moderate myopia (< or = -6.00 D) and Group II with severe myopia (more than -6.00 D).

RESULTSIn group I, uncorrected visual acuity more than and equivalent to 1.0 was in 40 eyes (93.02%), more than and equivalent to 0.8 in 43 eyes (100%). In group II, uncorrected visual acuity larger than and same as 1.0 was in 37 eyes (71.15%), larger than and same as 0.8 in 45 eyes (86.54%), larger than and same as 0.5 in 50 eyes (96.15%), and less than 0.5 in 2 eyes (3.85%). The mean spherical equivalent changed from (-4.14 +/- 0.86) D to (-0.04 +/- 0.14) D in group I and from (-9.00 +/- 1.64) D to (-0.08 +/- 0.20) D in group II. Significant difference was seen in these two groups (P < 0.001). The keratometric powers (K) were reduced from (44.31 +/- 0.78) to (40.11 +/- 1.23) and from (45.46 +/- 1.00) to (38.01 +/- 1.73) respectively, which showed significant difference (P < 0.001).

CONCLUSIONThe effectiveness of LASIK for mild to moderate myopia or severe myopia is promising and safe.

Objective To analyze and study the diagnosis of large granular lymphocyte leukemia(LGLL).Methods To report and discuss six cases weth LGLL we have found. Results 2 of T-LGLL and lof NK-LGLL had indolent process, mainly presenting with anemia and splenomegaly and good response to treatment, while; 1 of T-LGLL and 2 of NK-LGLL had aggressive process, their clinical characters are obviously general symptom, hepatomegaly,splenomegaly,these disease develop quickly and have bad prognosis. The immunophenotype of indolent LGLL is distinct from aggressive cases. Conclusion As a group of heterogeneous disease,its diagnosis should be based on clinical manifestation and immunophenotype and differentiated it carefully.

Objective To investigate the clinical and laboratory diagnosis of adult hemophagocytic syn-drome (HPS) . Methods Clinical data of 24 patients with HPS from 2000 to 2008 were retrospectively analyzed. Results Of the 24 HPS cases, 12 had a malignant associated hemophagocytic syndrome (MHAS), and 10 were fi-nally diagnosed by bone marrow immunohistochemist ;Of 12 cases in non-MAHS group,4 were with virus associated hemophagocytic syndrome (VAHS), and 4 were of the other infections, whereas 4 patients diagnosed of immune associated HS (MAS). There were significant difference in onset age, mortality, serum lactate dehydrogenase (LDH) and serum ferritin(FER) and neutrophilic NAP between non-MAHS group and MAHS group(P <0.01 ,P<0.05). In all cases bone marrow biopsy showed significant differences in cytological and pathological features between MAHS group and non-MAHS group. Conclusion Etiology,immunology,and bone marrow cell biopsy and pathology as well contribute to the diagnosis and typing of HPS and will give a guide to the therapy.

Objective To analyze the present situation of the preoperative visit for percutaneous coronary intervention (PCI) patients at home and abroad,and provide the reference for the preoperative visit of percutaneous coronary intervention in China. Methods We searched PubMed,Embase,Web of Science,CNKI,WanFangData,VIP,and CBM database by the computer.Then the articles for up to December 2017 which in accordance with inclusion criteria were analyzed by descriptive analysis. Results A total of 25 papers were included from 1983 to 2016, which had involved 8 articles in English and 17 in Chinese.The study of abroad began in 1983,and in China the first was in 2004.From 2008, the number of literatures were uptrend.The contents of the study were mainly about demand survey,current situation analysis,technology and effect evaluation,which the largest number of PCI visit was the aspect of effect evaluation,accounting for 68％ (17/25) of the total literature. Conclusion There is a high requirement for PCI information before the operation, but there is lack of unified standard content and process for PCI visits both at home and abroad.It is important measures to strengthen the training of specialized nurses for cardiovascular intervention and formulate standardization content and procedure of preoperative visit in order to development and further improvement of preoperative visit.

Objective To investigate the status quo,influencing factors and training willingness of rescue knowledge in elderly people so as to provide the basis for formulating the elderly rescue training programs.Methods A total of 488 elderly people in three urban districts of Guiyang City were sampled by simple random and convenient sampling methods.The self-made elderly people rescue knowledge and skill status quo questionnaire was used to conduct the investigation.The general condition,training status quo and willingness were descriptively analyzed.The rescue knowledge score adopted the independent sample t test and variance analysis.Results The rescue knowledge status quo:the awareness rate of medical emergency call was the highest(66.6％),and the rest rescue awareness rate was less than 20.0 ％.The training status quo and willingness:the people receiving the rescue knowledge training orly accounted for 13.3％.91.9 ％ and 94.1％ of the elderly people considered it necessary and were willing to participate in the rescue knowledge training.The pathways obtaining the rescue knowledge:network media and families or friends introduction accounted for 37.5 ％ and 22.4 ％ respectively,followed by books and magazines,publicity column and related knowledge lectures.The influencing factors:the knowledges and skills grasping situation in the elderly people experiencing the rescue training was better than those without experience.The higher the education level,the better grasping the rescue knowledge.The grasping situation in different occupations from high to low were special technical staffs,administrative staffs,workers and farmers.Conclusion The elderly people are short of rescue knowledge,their willingness of the first aid training is strong.The government and relevant agencies should jointly perfect the first aid law and first aid training system,and formulate the rescue training program that suitable for the elderly physical and mental characteristics,increase the rescue training strength and increase the rescue ability of the elderly people.

OBJECTIVETo compare therapeutic effects of warm needle moxibustion and medication on osteoporosis and to study the mechanism.

METHODSForty cases were randomly divided into an acupuncture group and a medication group, 20 cases in each group. The acupuncture group was treated by warm needle moxibustion at Dazhu (BL 11), Ganshu (BL 18), Shenshu (BL 23), Zusanli (ST 36), Yanglingquan (GB 34) etc. once other day, for 3 months; and the medication group was treated by oral administration of tablet Caltrate with Vit D2 for 3 months. The changes of bone mass density (BMD), estradiol (E2), osteocalcin (bone growth protein, BGP), urine calcium/creatinine (Ca/Cr) in the two groups before and after treatment and therapeutic effects were investigated.

RESULTSAfter treatment, BMD significantly increased (P<0.05, P<0.01) in the acupuncture group and did not signifi cantly changed in the medication group (P>0.05) with a significant difference between the two groups (P<0.05). After treatment E2 level significantly increased as compared with before treatment in both of groups (P<0.01); after treatment BGP significantly decreased as compared with before treatment in both of groups (P<0.01); after treatment Ca/Cr significantly decreased as compared with before treatment in the acupuncture group (P<0.05) ; af ter treatment, there were significant differences in BGP and Ca/Cr between the two groups (P<0.05 or P<0.01). The clinically controlled rate in the acupuncture group and in the medication group were 35.0%, 5.0%, respectively, the therapeutic effect of the acupuncture group being better than that of the medication group (P<0.01).

CONCLUSIONThe therapeutic effect of warm needle moxibustion on osteoporosis is better than that of oral administration of tablet Caltrate with Vit D2 and it can increase levels of hormones and delay bone loss. It is an effective method for preventing and treating postmenopausal osteoporosis.

OBJECTIVETo evaluate the static and dynamic contrast sensitivity changes in myopic patients before and after laser in situ keratomileusis (LASIK).

METHODSSeventy-three eyes in 37 patients with myopia (with or without astigmatism) who received LASIK were tested for static and dynamic contrast sensitivities using the METRO VISION MON ELEC I system at 0.7, 1.4, 2.7, 5.5, 11, and 22 cpd and cps prior to LASIK, and at one-, three-, and six-month intervals after LASIK.

RESULTSAll eyes gained naked visual acuity of more than 0.5 after LASIK. The contrast sensitivity was depressed at all frequencies 1 month after LASIK, as compared to one week prior to LASIK. The depression at 2.7, 5.5, 11 (P < 0.01) and 22 cpd (P < 0.05) was statistically significant for static contrast sensitivity, and also at 5.5 (P < 0.01) and 11 cps (P < 0.05) for dynamic contrast sensitivity. Myopic eyes between 6.25 D and 14.0 D, and astigmatic eyes 2 DC and more, suffered more static and dynamic contrast sensitivity depression than the myopic eyes between 1.25 D and 6.00 D and astigmatic eyes less than 2 DC. Contrast sensitivities were improved and exceeded preoperative levels 3 months after LASIK, and improved even more 6 months after LASIK. All sequences were statistically significant for static contrast sensitivity (P < 0.01), while only 2.7, 5.5, and 11 cps were statistically significant for dynamic contrast sensitivity (P < 0.01). The astigmatic eyes 2 DC and more showed less improvement, even below the preoperative level at 1.4 cps of dynamic contrast sensitivity.

CONCLUSIONSWhile temporary depression of contrast sensitivity for myopic eyes after LASIK was seen, contrast sensitivity soon returned to exceed preoperative levels at 3 months after LASIK, while improving even more 6 months after LASIK.

OBJECTIVETo discuss the diagnosis and treatment of primary hepatic carcinoid tumor (PHCT).

METHODSReport one case of huge PHCT treated in February 2004, and search the other 19 cases which were published from January 1994 to December 2006 in the Chinese biological and medical literature database. The clinical manifestation, pathological findings, diagnosis and treatment of these 20 PHCT patients were analyzed retrospectively.

RESULTSThe main symptoms were abdominal pain or discomfort (8 cases) and abdominal mass (7 cases), cases with typical carcinoid syndrome were rare (3 cases). Immunohistochemical staining was positive for neuron-specific enolase, chromogranin A and synaptophysin in most cases. Sixteen cases received operation, among which there were 13 removed completely, other 4 cases were treated by transcatheter arterial chemoembolization (TACE).

CONCLUSIONSThe definite diagnosis of PHCT depends on pathological and histochemical findings. Complete surgical resection is the best treatment for PHCT with favourable prognosis. TACE is also effective for nonoperative cases.

OBJECTIVESTo detect the loss of heterozygosity (LOH) of circulating DNA in the plasma of patients with hepatocellular carcinoma (HCC), and to assess its potential as a clinical predictive marker.

METHODSThree high-polymorphic microsatellite markers D8S277, D8S298 and D8S1771 located at chromosome 8p were selected to detect LOH in plasma DNA of 62 HCC patients. The associations between LOH and its clinicopathological features, including HBsAg, liver cirrhosis, serum AFP level, tumor size, tumor cell differentiation, and intrahepatic metastasis were also examined.

RESULTSIn plasma DNA of the 62 HCC patients, LOH was found at one or several loci in 36 (58.1%), and heterozygosity at D8S277, D8S298, and D8S1771 loci was 74.2% (46/62), 75.8% (47/62), and 69.4% (43/62), respectively. LOH frequency at D8S277, D8S298 and D8S1771 was 32.6% (15/46), 44.7% (21/47), and 46.5% (20/43), respectively. LOH in plasma DNA was more frequently detected in the patients with intrahepatic cancer metastasis than those without metastasis (62.5 percent vs. 26.1 percent, P < 0.05); however, no statistically significant correlations were observed between LOH at these loci and other clinicopathological features analyzed in this study.

CONCLUSIONSLOH at D8S298 in plasma DNA may be a potential predictive marker of intrahepatic metastatic recurrence after surgical resection of the HCC.
