Objective To investigate the clinical and laboratory characteristics of acute myeloid leukemia (AML) with t (16;21)(p11;q22) translocation.Methods Two patients diagnosed by morphology,cytochemical stain,immunology,cytogenetics and genetic testing.Similarities and differences of clinical characteristics and laboratory examination were analysed,along with a review of the literatures.Results According to the FAB classification,one patient was M4 and the other one was M1.The cytogenetic aberrations were 46,XY,t(16;21)(p11;q22)[16]/47,XY,t(16;21)(p11;q22),+21[4] of ease 1 and 46,XX,t(16;21)(p11;q22)[20] of case 2.Cytophagocytosis and CD56 antigen expression were found in both cases.The prognosis was poor in both cases.Conclusions AML with t(16;21)(p11;q22) is a specific type,which has unusual characteristics of morphology,immunology,cytogenetics,clinical feature.The prognosis of the patients is poor,so stem-cell transplantation maybe the only and the first choice of treatment.

Objective To evaluate the clinical efficacy of detachable balloons,detachable coils and intracranial covered stents in management of intracranial giant aneurysms.Methods From April 1998 to March 2006,20 patients with a giant or very large aneurysm were treated by parent artery occlusion(PAO), coils embolization and covered stent,in which 9 aneurysms were treated by PAO,8 by coils embolization and 3 by covered stent at initial management.Two recurrent aneurysms treated by coils embolization were performed by covered stent.Follow-up 9-83 months,mean 41.1?25.3 months.Immediate postprocedural angiographic outcomes were categorized as complete occlusion(100%),subtotal occlusion(95%-99%),and incomplete occlusion(＜95%)of the aneurysms;and follow-up angiographic outcomes were categorized as stable, thrombosis,and recanalization.Clinical outcomes were graded according to a modified Glasgow Outcome Scale (GOS).Results Endovascular treatment was technically feasible in all aneurysms without procedural-related complications.Immediate postprocedural angiograms showed complete occlusion was achieved in 11 aneurysms, subtotal occlusion in 7 and incomplete occlusion in 2.One patient with incomplete occlusion died on the seventh day with a rebleeding.The final angiographic findings in nineteen survival patients confirmed a complete occlusion in 15 aneurysms,subtotal occlusion in 3 and incomplete occlusion in 1,in which 10 parent arteries were successfully preserved.No rebleeding occurred during the follow-up period.The clinical evaluation performed at final follow-up in 19 patients revealed that the symptoms disappeared in 11 patients and improved in 8 in the modified GOS.Conclusions Treatment of giant intracranial aneurysms with coiling was associated with a low complete occlusion rate and a high recanalization rate.Treatment with endovascular parent artery occlusion remains practical,but this technique may result in damage to the parent artery and cause cerebral ischemic events.The use of an intracranial covered stent proved to be a relatively simple and safe procedure and maintained the pateney of the parent artery.

OBJECTIVETo explore the norms of treatment of acute organophosphorus pesticide poisoning (AOPP), and observe the curative effect.

METHODSOn basis of the pre-research, the norms of treatment of AOPP were summarized, and a multi-center clinical trial was performed in 6 hospitals selected from high incidence of AOPP in Shandong Province.

RESULTS422 patients of AOPP in 6 hospitals in observation period were treated and observed by the norms of treatment. Among them, the proportion of oral poisoning was 97.16%, middle and severe degree were 87.44%. Compared with themselves 2 years ago before standard treatment, the curative effect of the norms of treatment for AOPP was much better than before. The mortality rate of AOPP declined from 9.87% to 1.66% (Chi2 = 27.92, P < 0.01), that was much better than the average therapeutic effect level of all our province in the same period (the mortality rate: 8.92%) (Chi2 = 26.05, P < 0.01). The average amount of atropine [(37.54 +/- 17.76) mg], dropped greatly [(1280.70 +/- 69.22) mg] (U = 439.22, P < 0.01).The usage of atropine by continuous intravenous injection with venous pump was better than ordinary intravenous injection. The mean dosage of pralidoxime chloride increased twice than the previous (U = 19.48, P < 0.01). There was no drug poisoning.

CONCLUSIONThe standard treatment of AOPP is urgently needed in our country, especially in rural area. By this trial, the satisfactory effect of the norms of treatment for AOPP summarized is observed and it reduces the fatality rate remarkably.

OBJECTIVETo analyze the value of intraoperative ultrasonography (IOUS) in the diagnosis and therapy of insulinoma.

METHODSFrom January 2000 to December 2007, the application of intraoperative ultrasonography used in 44 cases with insulinoma who came from department of general surgery, First Affiliated Hospital of Zhengzhou University were retrospectively analyzed. There were 19 males and 25 females in the group. Every case accepted operation and examination of IOUS.

RESULTSTumor was accurately located and its adjacent structure was also clear by IOUS in 43 cases, the other one was islet cell hyperplasia, the detection rate of tumor was 100%. The complications: one case occurred pancreatic fistula, one occurred pancreatitis, and there was no biliary fistula and hemorrhage.

CONCLUSIONSPresently, IOUS is one simple and effective method to local insulinoma, and it could improve the success rate of operation and reduce complications.

OBJECTIVETo study the abdominal adipose area, serum adiponectin and leptin levels of nonalcoholic fatty liver disease in elderly males.

METHODSA total of 238 elderly males (more than 60 years) were enrolled and divided into three groups: Nonalcoholic fatty liver disease (NAFLD) group (n = 76), matching group (age and body mass index matching with NAFLD group, n = 77), normal control group (n = 85). Serum levels of adiponectin and leptin were measured by RIA (radiological immunological assay). Abdominal adipose area was detected by computer tomography.

RESULT(1) body mass index (BMI), abdominal subcutaneous adipose area, visceral adipose area, total adipose area of NAFLD group and matching group were (26.87+/-2.62) kg/m2 and (26.63+/-1.97) kg/m2, (166.59+/-54.27) cm2 and (147.89+/-50.14) cm2, (148.94+/-53.72) cm2 and (150.06+/-45.47) cm2, (315.25+/-89.42) cm2 and (297.93+/-75.12) cm2, respectively; and were higher than those in control group (P less than 0.01). The abdominal subcutaneous adipose area is higher in NAFLD group than in matching group, however, the abdominal visceral adipose area and total adipose area were not significantly different between those two groups. (2) The serum leptin level in NAFLD group and matching group was significantly higher than that in control group, and serum leptin level was not significantly different between NAFLD group and matching group. The serum adiponectin of NAFLD group [(6.31+/-3.31)mug/ml] was significantly lower than that of matching group [(9.87+/-7.071)mug/ml, P less than 0.01] and control group (P less than 0.01). There was no difference in adiponectin level between matching group and control group. 3) AST, TG, abdominal subcutaneous adipose area, abdominal visceral adipose area were risk factors of NAFLD, while serum adiponectin was protective factor of NAFLD.

CONCLUSIONThese data indicate that elderly male NAFLD patients manifest abdominal obesity, high serum leptin, low serum adiponecin, and suggest that adiponectin may play a crucial role in the pathogenesis of NAFLD in elderly males.

OBJECTIVETo find sensitive and specific micro-metastic markers for prostate cancer.

METHODSUsing nested reverse transcription-PCR, we examined the expression of PSA, hK2 and PSMA mRNA in peripheral blood mononuclear cells of 51 patients with prostate cancer, 33 patients with benign prostate hyperplasia (BPH) and 32 normal young people.

RESULTSThe expression rates of PSA, hK2 and PSMA mRNA were 52.9%, 43.1% and 64.7%, respectively in prostate cancer group, and 6.2%, 7.7% and 4.6%, respectively in control group (BPH patients and normal young people) with statistical significance (P < 0.01). Although the expression rate of PSA and hK2 mRNA increased with cancer progression, there was no statistical significance among patients in different stages. The expression rate of PSMA mRNA was higher than that of PSA and hK2 mRNA in each clinical stage.

CONCLUSIONPSMA mRNA expression detected by nested RT-PCR is of greater value for the diagnosis, therapy choice and prognostic evaluation of prostate cancer patients.

Objective To predict the incidence of hand, foot and mouth disease (HFMD) in Shijiazhuang using the multiple seasonal autoregressive integrated moving average model (ARIMA) and long short term memory (LSTM) model, lay theoretical foundation for the prevention and control of HFMD. Methods Multiple seasonal ARIMA model and LSTM model were established separately by using Eviews 8.0 and python 3.7.1 according to the data of monthly incidence of HFMD from January 2013 to May 2018 in Shijiazhuang, and the data from June 2018 to May 2019 were used to verify the prediction precision of model. Finally, the monthly incidence from June to August 2019 was predicted. Results Based on the monthly incidence from January 2013 to May 2018, the optimal models, ARIMA(1,0,0)×(1,1,2)12 and LSTM model were established. Mean absolute percentage of error (MAPE) of ARIMA and LSTM model were 22.14 and 10.03 respectively based on the monthly incidence from June to December 2018, while MAPE of ARIMA and LSTM model were 43.84 and 25.26 respectively based on the monthly incidence from June 2018 to May 2019. These results indicated that LSTM model was superior to ARIMA model in model fitting degree and predicting accuracy, which was relatively consistent with the actual situation. Conclusions LSTM model is able to fit and predict the incidence trend of HFMD well in Shijiazhuang. It can provide guidance to HFMD epidemic prediction and alerting.
