ObjectiveTo investigate the current situation of immunophenotyping of acute leukemia by flow cytometry in China (except Taiwan, Hongkong and Macau), and to provide theoretical evidence for the formulation of guidelines of immunophenotyping of leukemia by flow cytometry.MethodsThe Chinese Hospital Knowledge Database(CHKD) was used to retrieve the1994-2009 published papers on immunophenotyping of acute leukemia by flow cytometry.All of 380 retrieved papers were analyzed by the GraphPad Prism 4. ResultsThe number of published papers in China increased yearly and changed gradually from large cities to small and medium-sized cities in local distribution. The most often reported area was Beijing, followed by Jiangsu and Guangdong. In specimen processing, the ratios of using mononuclear cell labling method and whole blood labling-lysing-washing method were 34.2 ％ (113/330) and 65.8 ％ (217/330) respectively. The ratios of using single color, two color, three color and four color labling method were 15.4 ％ (53/344), 13.7 ％ (47/344), 54.1％ (186/344) and 16.3 ％ (56/344), respectively. The number of fluorescent antibodies was used from less than 10 to more than 20.Most of them were between 11 to 16,which was 48.6 ％ (167/344) of total number of published papers. In data acquisition and analysis, the ratios of using FSC/SSC gating and CD45/SSC gating were 34.2 ％ (113/330) and 65.8 ％ (217/330), respectively. There were some differences in the positive criteria of lymphatic and myeloid and cytoplasm antigens.The main positive criteria of lymphatic, myeloid antigen was ≥20 ％, which was 64.8 ％ (223/344) and 95.4 ％ (328/344) . The main positive criteria of cytoplasm antigen was ≥ 10 ％, which accounted for 61.2 ％ (156/255). Conclusion A common view has been reached in specimen processing,gating method,data acquisition and analysis in immunophenotyping of acute leukemia by flow cytometry. But there were still some difference in the number of fluorescent antibodies, panels and evaluation of positive criteria of antigens.

Abstract: Objective　To evaluate the completion and final effect of key parasitic disease prevention and control planning tasks in Hubei Province from 2016 to 2019, summarize the experience, find out the problems, and provide the basis for the next stage of prevention and control. Methods　According to the requirements of the Final Evaluation Plan of the National Plan for the Prevention and Control of Hydatid Disease and Other Major Parasitic Diseases (2016-2020), a retrospective survey method was adopted to collect relevant data on the implementation and safeguard measures of the prevention and control of major parasitic diseases, and population infection status in Hubei Province in 2016-2019. Results From 2016 to 2019, We carried out 2 920 992 person times of publicity and education, 209 times of prevention and control technology training, 7 680 person times of business training, with an average of 52 sessions and 1 920 person times per year. We have allocated 3.445 2 million yuan for the prevention and control of parasitic diseases, including 1.722 2 million Yuan froom provincial government, to achieved full coverage of safe drinking water in rural areas under the current national standards, and 7.687 9 million harmless toilets have been built in rural areas. From 2016 to 2019, we carried out 39 658 person times of monitoring and disease investigation, the infection rate of human liver fluke was 0, and the infection rate of soil transmitted nematode was 0.42%. While the annual infection rates varied, there was no statistically significant difference in infection rate between years (χ2＝2.276, P>0.05), but there were statistically significant differences in the infection rates between various soil nematodes (χ2=112.807, P<0.01). From 2016 to 2019, a total of 5 393 people were detected at 17 monitoring points, with the serum positive rate of 3.93% for paragonimiasis, there was a statistically significant difference in serological positive rate between years (χ2=146.011, P<0.01); a total of 738 stream crabs were collected, and the infection rate of intermediate host was 16.26%, wtih a statistically significant difference in the infection rate of stream crabs between years (χ2=49.731, P<0.01). Conclusions　From 2016 to 2019, we adhered to the prevention and control strategy of "prevention first, prevention and control combined", implemented comprehensively various prevention and control measures, and achieved remarkable results in Hubei Province. The key parasitic diseases have been in a low epidemic situation, meeting the requirements of the prevention and control objectives. But the transmission risk still exists, the next step is to continue to strengthen security and monitoring and consolidate the achievements of prevention and control.

OBJECTIVETo compare the difference in the clinical efficacy on cervical spondylosis of vertebral artery type (CSA) treated with thermosensitive moxibustion at different dosages.

METHODSSixty cases of CSA were randomized into a saturated moxa dosage group and a regular moxa dosage group, 30 cases in each one. The thermosensitive moxibustion was adopted in the two groups. The mild suspended moxibustion was applied at two acupoints with the strongest thermosensitization. In the saturated moxa dosage group, the moxibustion time was determined by the disappearance of thermosensitization. In the regular moxa dosage group, 15 min was required on each acupoint. The treatment was given twice a day for first 4 days in the two groups. Since the 5th day, the treatment was given once a day, continuously for 10 times, and totally 14 days were required. The score of symptoms and function and clinical efficacy were compared between the two groups before and after treatment as well as 6-month follow-up after treatment.

RESULTSThe curative and effective rate was 56.7% (17/30) after treatment and 60.0% (18/30) in 6-month follow-up after treatment in the saturated moxa dosage group, which were superior to 26.7% (8/30) and 30.0% (9/30) in the regular moxa dosage group respectively (P < 0.01, P < 0.05). The scores of clinical symptoms and function after treatment and in follow-up were improved apparently as compared with those before treatment in both groups (all P < 0.01). The scores of clinical symptoms and function after treatment and in follow-up in the saturated moxa dosage group were increased much more apparently than those in the regular moxa dosage group (after treatment: 22.32 +/- 4.64 vs 17.43 +/- 3.21; in follow-up: 23.01 +/- 4.76 vs 18.32 +/- 2.13, both P < 0.01).

CONCLUSIONThe thermosensitization moxibustion of saturated dosage achieves the superior short-term and long-term efficacies in the treatment of CSA as compared with the regular moxibustion dosage.

The cases of lymphoma accompanied or preceded by Coombs' test positive autoimmune hemolytic anemia (AIHA) have been reported. However, Coombs' test negative AIHA prior to the diagnosis of lymphoma was rarely described. Herein, this article reports a case of non-Hodgkin's lymphoma (NHL) preceded about 1.5 years by Coombs test negative AIHA. A woman aged 69 was diagnosed with HA based on the history and laboratory tests. Further studies revealed that this patient was negative with Coombs' test for IgG, IgM, IgA and C3. After all possible causes of HA, especially malignancies were ruled out, the patient was diagnosed with Coombs' test negative AIHA and treated with prednisolone. The patient responded well initially to steroid treatment. Two recurrences of acute HA were presented at time of 10 months post steroid cessation, and immediately after an attempt to withdraw steroid, respectively, but the hemolysis was effectively controlled by reinstitution of prednisolone. At third recurrence, however, the patient was no longer responding to steroid, and was found with cervical lymphadenopathy. Coombs' test for IgG, IgM, IgA and C3 remained negative. B cell NHL was diagnosed by pathology. After receiving 6 cycles of CHOP chemotherapy, the patient was lymphoma free, but the hemolysis was not improved, however, which was effectively controlled by the following low dose-rituximab (RTX) therapy. The patient was still kept in a remission of lymphoma free of anemia. In conclusion, this report presented a very rare case of NHL with Coombs' test negative AIHA as initial major clinical manifestation.

Objective: To assess the risk of public health emergencies in Zhejiang Province, March 2021. Methods: An expert counsel was conducted to assess the risk of coronavirus disease 2019 ( COVID-19 ) , enteritis due to norovirus, chicken pox and influenza by professionals in Zhejiang CDC, based on the information from infectious disease and public health emergency surveillance in Zhejiang Province, domestic health administrative departments, World Health Organization, and European CDC. Results: In March 2021, the risk of imported COVID-19 epidemic will be high in Zhejiang Province, and the possibility of local spread could not be ruled out. The possibility of a large-scale outbreak of enteritis due to norovirus and a small-scale outbreak of chickenpox in schools and kindergartens could not be ruled out after the new term begins. An increased risk of influenza epidemic is predicted in collective units such as schools and kindergartens, yet the risk of a large-scale one will be low. Conclusion High attention should be paid to COVID-19 and enteritis due to norovirus, and general attention should be paid to chicken pox and influenza outbreak.

OBJECTIVETo describe the mortality of esophageal cancer (EC) in China during 2004 - 2005, and its trends over past 30 years.

METHODSThe Third National Retrospective Sampling Survey of Death Causes in 2004 - 2005 was covered 142 660 482 person years (72 970 241 person years in male, 69 690 241 person years in female; 47 899 806 person years in urban, 94 760 676 person years in rural). All death records of EC cases were selected. Crude, age-adjusted mortality, the proportion to all cancer deaths, and age-standardized death rate by Chinese standard population (CASR) and world standard population (WASR) were calculated. The statistic indexes of mortality were compared with those of previous retrospective death surveys in 1973 - 1975 and 1990 - 1992.

RESULTSDuring 2004 - 2005, the crude death rate of EC was 15.21/100 000 (21 694/142 660 482), CASR was 9.98/100 000, EC death accounted for 11.19% (21 694/193 841) and ranked fourth of all cancer death causes. The CASR of male (14.32/100 000, 15 067 cases) was higher than that of female (5.75/100 000, 6627 cases). In rural areas, there were 16 437 deaths caused by EC with CASR of 12.01/100 000, it was higher than in urban areas (CASR was 6.48/100 000, 5257 deaths). There were little different of EC mortality among Eastern, Central and Western areas in China. EC crude death rate in Eastern was the highest with rate of 16.67/100 000 (8761/52 556 694) and the lowest rate was 12.92/100 000 (5209/40 322 563) in Western area. EC crude death rate was increased by age increasing and reached the peak with mortality of 180.55/100 000 (1984/1 098 885) at age group of 80-. The CASR of EC was reduced by 41.64% compared with the first survey (CASR was 17.10/100 000) in 1973 - 1975, and reduced by 33.56% compared with the second survey (CASR was 15.02/100 000) in 1990 - 1992.

CONCLUSIONAlthough the EC mortality has dropped obviously in the past three decades, it is still the main cancer burden, especially in rural areas. EC prevention and control should be focused on the rural high risk areas in China in future.

OBJECTIVETo investigate the effect and possible mechanism of complete Freund's adjuvant induced chronic pain on later function of learning and memory in neonatal rats.

METHODSSixty Sprague-Dewley rat pups (10 litters of 6 pups) were randomly divided into control group and chronic pain group (n = 30 in each group). In the chronic pain group, left hind paws of the rats were treated with subcutaneous injection of 20 microl of CFA on postnatal day-2. The control rat pups received normal saline. The hippocampus of rats were separated on postnatal days 10 and 21 (one rat in each group from every litter, n = 10). The expression of Bcl-2 and BDNF mRNA were investigated by RT-PCR. Morris water maze tests were performed on day 21 (one rat in each group from every litter, n = 10).

RESULTSIn hidden-platform training of Morris water maze, the mean escape latency of rats in the chronic pain group were longer than that of the control rats. In spatial probe tests, the average percentages of the swimming time and distances in the platform quadrant in the pain group rats were less than those in the control group. There was no significant difference in visible-platform training between the two groups. The Bcl-2 and BDNF mRNA expressions in hippocampus of the pain group rats were lower than those in the control at day 10, but no significant difference at day 21.

CONCLUSIONChronic pain stress induced by CFA impairs the spatial learning and memory function in neonatal rats. These effects might exert through down-regulating Bcl-2 and BDNF mRNA expression in the hippocampus.

·AIM: To investigate the efficacy of intravitreal injection of Conbercept in the treatment of diabetic macular edema (DME). ·METHODS: Totally 95 patients(95 eyes) with diabetic macular edema treated in our hospital from January 2014 to December 2016 were retrospectively analyzed, and 42 cases received Ranibizumab intravitreal injection were included into control group, 53 cases treated with conbercept intravitreal injection were included into observation group. The changes of preoperative and postoperative follow up visual acuity and macular foveal thickness in the two groups were observed. The repeated medication, complications and medical expenses were also compared. ·RESULTS:The preoperative best corrected visual acuity between groups showed no difference (P>0. 01). The postoperative best corrected visual acuity between groups showed distinct difference (F = 105. 326, P<0. 01; F =86.365,P<0.01). At 3mo after the operation,visual acuity of two groups sharply improved, a significant difference was shown within the groups (P<0. 05), but held no obvious difference between groups (P>0. 05). At 6mo after operation,the observation group's visual acuity was evidently higher than that at 3mo (P<0.05). The visual acuity at postoperatively 6mo of the observation group was significantly higher than that of the control group,the difference between groups was statistically marked (P<0.01). The control group's visual acuity at postoperative 3 and 6mo showed no marked difference (P>0.05). The overall changes of foveal thickness between two groups showed a significant difference (F=86.365, P<0.01; F=84.235,P<0.01). The foveal thickness reduced obviously during the postoperative 1, 3 and 6mo of followed up, which showed remarkable difference within groups (P<0.05) but no difference between groups (P>0.05). The repeated medication of observation group during the postoperative 1,3 and 6mo of followed up was evidently less than that of the control group,the difference between groups was significant (P<0.05). There was no statistical difference between groups in complications after operation (P>0. 05). The average medical cost of the observation group was obviously less than that of the control group,and the difference between the two groups was evident (P<0.01). ·CONCLUSION:Intravitreal injection of conbercept in the treatment of diabetic macular edema can effectively enhance vision and relieve macular edema, as well as shows lasting efficacy,low cost and high safety.
