ABSTRACT
Objective:To evaluate the efficacy of Peiyuan Kangai Decoction combined with acupuncture in the treatment of advanced liver cancer with qi deficiency and blood stasis syndrome.Methods:Randomized controlled trial. From May 2019 to May 2021, 162 advanced liver cancer patients with qi deficiency and blood stasis syndrome in Shizhong District Cancer Hospital of Leshan were randomly divided into three groups by random drawing method, with 54 in each group. All patients were given FOLFOX4 chemotherapy regimen. Based on the chemotherapy, the 1st control group was given Peiyuan Kangai Decoction, and the 2nd control group was given acupuncture therapy, and the combined group was given decoction and acupuncture therapy. All three groups were treated for 6 weeks. Traditional Chinese Medicine syndrome score was performed before and after treatment, Piper fatigue scale was used to evaluate the fatigue degree of patients. Vimentin (VIM), Golgi transmembrane glycoprotein 73 (GP73) and chemokine ligand 1 (CXCL1) were determined by ELISA. The adverse reactions during treatment were observed and the clinical efficacy was evaluated.Results:The combined group showed the response rate was 61.11% (33/54), the disease control rate was 72.22% (39/54), the 1st control group showed the response rate was 40.74% (22/54), the disease control rate was 53.70% (29/54), and the 2nd control group showed the response rate was 38.89% (21/54), and the disease control rate was 51.85% (28/54). The response rate and disease control rate of the combined group were significantly higher than either the control group 1 and 2 ( χ2 values were 6.59, 5.68, respectively, and P values were 0.037, 0.043, respectively). After treatment, the scores of liver swelling and pain, fatigue and shortness of breath, anorexia, sallow and emaciation in the combined group were significantly lower than those in the control group 1 and the control group 2 ( F values were 13.90, 15.69, 13.20, 10.55, respectively, P<0.01); the scores of emotions, feeling, behavior and cognition were significantly lower than those in the control group 1 and control group 2 ( F values were 49.55, 27.42, 19.69, 20.55, respectively, P<0.01). After treatment, the levels of serum VIM [(52.54±6.69) ng/L vs. (61.29±7.89) ng/L, (65.11±7.92) ng/L, F=39.63], GP73 [(19.72±3.90) ng/L vs. (24.42±4.23) ng/L, (25.12±4.76) ng/L, F=25.05], CXCL1 [(3.12±0.72) ng/L vs. (4.85±0.95) ng/L, (4.98±0.91) ng/L, F=77.67] in the combined group were significantly lower than those in the control group 1 and the control group 2 ( P<0.01). During the treatment, the incidence of toxic and side effects in the combined group was 18.52% (10/54), the control group 1 was 27.78% (15/54), and the control group 2 was 24.07% (13/54). There was no statistically significant difference in the incidence of toxic and side effects among the three groups ( χ2=1.31, P=0.520). Conclusion:On the basis of FOLFOX4 chemotherapy, combined therapy with Peiyuan Kangai Decoction and acupuncture treatment can improve the symptoms and fatigue of patients with advanced liver cancer, reduce the levels of serum VIM, GP-73, CXCL1, improve the efficacy safely.

ABSTRACT
Objective@#To investigate the pathological features and clinical manifestation of pediatric nodal marginal zone lymphoma(NMZL).@*Methods@#Histological morphology and immunophenotype of 7 cases of pediatric NMZL were retrospectively reviewed at Beijing Friendship Hospital Affiliated to Medical University between January 2008 to October 2018. Clonal rearrangement analysis was performed. Clinical information including patient follow-up data were analyzed.@*Results@#All 7 patients were male with a median age of 15 years aged from 10 to 26 years. All patients presented with only lymph node enlargement without B symptoms, including cervical lymph node (5 cases), preauricular lymph node (1 case) and retroauricular lymph node (1 case). Histologically, all cases showed irregular large follicles on the edges with widened marginal areas and intervesicular areas, and lesional cells were uniform with progressive transformation of germinal center centers along with a small amount of intrinsic lymphoid tissue. All 7 cases showed diffuse CD20 positivity both follicle and interfollicular region along with 30%-40% positivity in the interfollicular region (pathological region). Markers of other B-cell lymphomas werenot expressed. All 7 cases were positive for immunoglobulin(Ig) gene rearrangement. None of the patients showed no recurrence up on after follow-up for an average of 13 months.@*Conclusions@#Pediatric NMZL is a rare type of lymphoma that has a unique morphology and occurs almost exclusively in male children and young adults and often in head and neck lymph nodes. It has an excellent prognosis. Therefore, awareness of the disease with accurate diagnosis is important.
ABSTRACT
Objective: To investigate the effect of self-etching adhesive with different unsealing time on the microleakage of the adhesive interface between tooth and resin. Methods: Unopened self-etching adhesives, Scotchbond Universal (S) and Xeno V+ (X) were respectively used to adhere Z350 resin for restoration of the prepared occlusal cavities sized 4 mm × 4 mm × 4 mm (n = 40) . The methylene blue staining method was used to observe the microleakage of the adhesive interface between the tooth and filling material at the instant moment, 1, 2 and 3 months after the self-etching adhesives was opened (n = 10) . Results: (1) Increase of microleakage in S group was found with the time span after unsealing, and there was a statistical difference between the instant moment and 3 months after unsealing (P＜0. 05) . (2) There was no significant difference at the 4 test time points in X group (P＞0. 05), although the microleakage value of the samples were increased with the increase of the time after unsealing. (3) The microleakage of X group was greater than that of S group at the instant moment and 1 month after unsealing (P＜0. 05) . Conclusion: Unsealing time may increase the microleakage of the adhesive interface between the tooth and the filling material, the effect varies with the types of the adhesives.

Objective@#To investigate clinicopathologic features and prognostic factors of mantle cell lymphoma(MCL).@*Methods@#The clinical data of 349 MCL patients diagnosed at Beijing Friendship Hospital from January 2004 to January 2016 were retrospectively collected. Corresponding histological sections were reviewed. Additional studies included immunohistochemical staining using the MaxVision two-step method, IgH/CCND1 fusion gene detection by fluorescent in situ hybridization (FISH), and correlative statistical analysis.@*Results@#Of 349 patients with MCL, the median patient age was 61 years (range: 25-83 years, M∶F=2.7∶1.0) and the age of 243 patients ranged from 51 to 70 years (69.6%). Those with B symptoms accounted for 22.4% (70/313). Most of the patients presented with superficial lymphadenopathy and the clinical stage Ⅲ-Ⅳ accounted for 76.1% (235/309). Extranodal involvement was seen in 47.9% (148/309), among which the gastrointestinal tract accounted for 31.8% (47/148) and splenic involvement accounted for 15.4% (47/305). Three hundred and nine (88.5%) cases were of classical type and 40 (11.5%) cases were of aggressive variant type, and all were composed of proliferating lymphoid cells. All the tumors were positive for CD20 and cyclin D1, and 98.6% (344/349) tumors were weakly positive or positive for CD5. FISH test was positive in 12 cases that were CD5 negative and with cyclin D1 partial expression.Two hundred and forty-three (69.6%) patients had a median follow-up of 26 months (range: 3-108 months). The 3- and 5-year overall survival rates for patients were 63.0% and 34.8%, respectively. Single factor analysis showed that age of >60 years, splenic involvement, aggressive variant type, incompletely overlapping type [Based on the degree of overlap ≥90% and <90% between the follicular dendritic cell (FDC) meshwork and tumor cells, the tumors were divided into the completely overlapped type and incompletely overlapped type] and Ki-67 index >40% had poor prognosis (P<0.05). Multiple factor Cox proportional risk regression analysis after removing the aggressive variant type showed that age, splenic involvement, the degree of overlap between the FDC meshwork and tumor cells and Ki-67 index were independent prognostic factors for overall survival rate of MCL patients (P<0.05).@*Conclusions@#MCL is more commonly found among middle-aged and elderly men. Patient age, splenic involvement, degree of overlap between FDC meshwork and tumor cells and Ki-67 index are the independent prognostic indicators for MCL.
ABSTRACT
Objective@#To investigate the clinicopathological features of EBV-positive T/NK cell lymphoproliferative diseases (EBV+ T/NK-LPD).@*Methods@#The clinical characteristics of 156 cases of EBV+ T/NK-LPD were collected from August 2002 to March 2015 at Beijing Friendship Hospital, Capital Medical University. Immunohistochemical staining, EBER in situ hybridization and clonal analysis of TCR gene were performed. All patients were followed up.@*Results@#There were 106 male and 50 female patients; patients′ age ranged from 1 to 75 years (median 20 years). The course of the diseases before diagnosis ranged from 2 to 540 months (median 20 months). Fever was noted in 122 patients (78.2%), 108 patients had lymphadenopathy (69.2%), and 75 patients had hepatosplenomegaly (48.1%). Thirty-three cases were grade 1, 68 cases were grade 2, and 55 cases were grade 3. TCR gene arrangement analysis was performed in 45 cases, and 33 cases (73.3%) showed clonal rearrangement. The follow-up period ranged from 1-134 months, and 44 patients (28.2%) died. There was a trend of increased death rate associated with increasing grade (P>0.05).@*Conclusions@#There are many types of EBV+ T/NK-LPD, and they can be classified as systemic, relatively localized and localized. The prognosis should be based on a comprehensive analysis of pathology and clinical data. There is no significant correlation between morphological grade and mortality. An important goal of therapy is to prevent serious complications.
ABSTRACT
Objective@#To investigate the clinicopathologic features and prognosis of gastrointestinal mantle cell lymphoma (GI-MCL).@*Methods@#Clinical data of 38 GI-MCL patients diagnosed at Beijing Friendship Hospital from January 2002 to January 2016 were retrospectively reviewed morphologically and immunophenotypically. IgH/CCND1 gene fusion was assessed by fluorescent in situ hybridization (FISH). For comparison, 60 cases of non-GI-MCL were randomly selected to extract the differences inclinicopathological features and patient survival between the two groups.@*Results@#Of 38 patients with GI-MCL, the median age was 62 years (range: 35-78 years, 23 males and 15 females), of which patients of 60 years of age or older accounted for 55.3%. Patients with clinical course of less than 6 months accounted for 81.1%(30/37). The main symptoms included abdominal pain, diarrhea, anorexia and hematochezia. Those with B symptoms accounted for 32.4%(12/37). The tumor most often involved lleocecal region (57.9%, 22/38), followed by rectum (36.8%, 14/38) and sigmoid colon (28.9%, 11/37), and the stomach accounted for 18.4%(14/38). Endoscopic polypoid lesions were found in 33 cases (86.8%, 33/38), of which 22 cases (66.7%, 22/33) were multiple. Five cases (13.2%, 5/38) presented with local protuberant neoplasm. According to Ann Arbor staging, 3 cases (7.9%, 3/38) were at stage Ⅰ, 4 cases (10.5%, 4/38) were at stage Ⅱ, and 31 cases (81.6%, 31/38) were at stage Ⅳ. The number of patients with tumor involvement of abdominal and retroperitoneal lymph nodes accounted for 45.7%(16/35), including 41.7%(15/36) involving the superficial lymph node, 17.1%(6/35) involving extranodal sites, and 23.5%(8/34) having splenomegaly. All of the 38 cases were classic MCL, and the tumor was composed of uniform lymphoid cells and effacing normal mucosal structure. All tumors were positive for CD20 and CD5. 97.4% (37/38) tumors were positive for cyclin D1, and 92.0% (23/25) tumors were positive for SOX11. FISH test was positive in 1 case of cyclin D1 negative tumor. Twenty-eight patients (73.7%) had a median follow-up of 25.0 months (range: 3-79 months). The 3-year survival rate for stage Ⅰ-Ⅱ and stage Ⅲ-Ⅳ of patients were 80.0% and 69.1%, respectively (P> 0.05). The 3-year survival rate for GI-MCL and non-GI-MCL patients were 71.7% and 72.5%, respectively (P>0.05). Single factor analysis showed that age of >60 years and splenomegaly were correlated with a worse overall survival rate (P<0.05).@*Conclusions@#Gastrointestinal malaise is the most common presenting symptom in GI-MCL patients. GI-MCL more commonly involves colorectum with more frequent multiple polypoid lesions. Patients of age >60 years and with splenomegaly have poor prognosis. There is no difference in the prognosis between GI-MCL and non-GI-MCL patients.
ABSTRACT
Objective@#To determine the cut-off values of Ki-67 labeling index (LI) in the histological grading of follicular lymphoma (FL).@*Methods@#Clinicopathological data of 350 FL patients diagnosed at Beijing Friendship Hospital from June 2014 to January 2016 were analyzed retrospectively by quantitative evaluation and statistical analysis of Ki-67 LI.@*Results@#Of the 350 patients with FL, the male and female ratio was 1.1 and the average age was (50.2±14.0) years with a median age of 51 years (range 4 to 82 years). The tumors were graded as grade Ⅰ-Ⅱ in 215 cases (61.4%), grade Ⅲ A in 105 cases (30.0%), and grade Ⅲ B in 30 cases (8.6%). The average Ki-67 values were (22.8%±8.3%) for the FL low (grade Ⅰ-Ⅱ) and (50.4%±10.7%) for high grade (Ⅲ A and Ⅲ B) and were statistically significant by Mann Whitney U test (P<0.01). Receiver operated characteristic curve analysis showed that the best diagnostic cut-off value of low grade FL was 35% (sensitivity of 96.3% and specificity of 93.3%) with the largest area under curve (AUC=0.990, P<0.01, 95%CI for 0.982-0.998). According to the analysis of four lattice diagnostic tests, Ki-67 LI >40% was an important factor (χ2=230.733, P<0.01) in predicting high grade FL. When the cut-off value of Ki-67 LI was set at 40%, high grade LF could be diagnosed with the greatest sensitivity (98.1%) and specificity (87.7%). Moreover, a significant correlation between the Ki-67 LI and the pathological grade of FL (r=0.836, P<0.01) was observed.@*Conclusions@#Ki-67 LI of below a cut-off value of 35% is a reliable indicator of low grade FL.Ki-67 over 40% is consistent with high grade FL. These Ki-67 cut-off values may serveas an important auxiliary indicator in the grading of FL.
ABSTRACT
Objective@#To analyze clinical, pathological, molecular and genetic characteristics of Burkitt-like lymphoma with chromosome 11q aberration.@*Methods@#A case of Burkitt-like lymphoma with 11q aberration was presented at Beijing Friendship Hospital in November 2016 with detailed clinicopathological features, immunophenotypes, Epstein-Barr virus(EBV) status and molecular genetic characteristics.@*Results@#The patient was a 38-year-old man presenting with the cervical lymphadenopathy. In morphology, the tumor had the similar characteristics of Burkitt lymphoma, including diffuse infiltration of medium to large lymphoid cells, and presence of"starry sky"phenomenon. Immunophenotypically, the tumor cells were positive for CD20, CD10, bcl-6, but negative for bcl-2. MUM-1 showed weak and patchy positivity. Ki-67 index was more than 95%. C-MYC expression was seen in about 50% of tumor cells. EBV in situ hybridization was negative. IgH and IgK genes were clonally rearranged.Fluorescence in situ hybrization detection using MYC break probe was negative but ATM gene amplification on chromosome 11q was detected. The patient did not receive any chemotherapy or radiotherapy and had not recurrence during the 10 months follow-up.@*Conclusion@#Burkitt-like lymphoma with chromosome 11q aberration has similar clinical, morphological and immunological characteristics to classic Burkitt′s lymphoma.
ABSTRACT
Objective@#To investigate clinicopathological features and prognosis of tonsillar mantle cell lymphoma(TMCL).@*Methods@#Clinical data of 25 patients with TMCL at Beijing Friendship Hospital, Capital Medical University from 2002 to 2016 were included. All the cases were reviewed microscopically. Various immunohistochemical stains were performed using the MaxVision two-step method. IgH/CCND1 gene fusion was detected by fluorescent in situ hybridization(FISH). Additionally, randomly selected 40 cases of non-tonsil MCL of the same period were compared.@*Results@#Among all mantle cell lymphomas (MCL), TMCL accounted for 5.6%(25/449). The median age of the patients was 60 years(range: 44-82 years) with a M∶F ratio of 5.3 to 1.0. The main symptoms were sore throat and foreign body sensation and patients usually presented with enlargement or mass of tonsil. At the early stage of the disease, 18 cases(72.0%) were clinically misdiagnosed as tonsillitis. Lymph node involvement was present in 76.0%(19/25) of the patients. There were 4 cases(16.0%)with current splenic involvement, 11 cases(44.0%) with pharyngeal focal recidivism, and 3 cases(12.0%) with involvement of other non-lymphoid organs. Morphologically, tonsillar architectures were effaced at various degrees. Eighteen MCL cases showed classical type and 7 cases were blastoid variant. All tumors were positive for CD20 and cyclin D1. 92.0%(23/25) tumors showed weakly positive or positive expression for CD5. FISH test that IgH/CCND1 gene fusion was positive in two CD5 negative classical cases. 18 patients(72.0%) had a median follow-up time of 26 months(range: 6-81 months). The difference of survival rate between stage Ⅰ-Ⅱ and stage Ⅲ-Ⅳ patients was not statistically significant(P>0.05). Compared with NTMCL, TMCL was found to have higher proportion of stage Ⅰ-Ⅱ disease (χ2=12.789, P<0.01), lower the proportion of non-lymphatic organ involvement (χ2=8.125, P<0.01), and better prognosis (χ2=4.351, P=0.037).@*Conclusion@#The incidence of TMCL is low and prone to be misdiagnosed as tonsillitis. Patients with TMCL are more likely at stage Ⅰ-Ⅱ at presentation and the prognosis is better than that of NTMCL.
ABSTRACT
Cancer stem cells are thought to be the seed of tumor formation, through complex signalings and cytokines in the surrounding microenvironment regulate the development and metastasis of tumor.Tumor stem cells have the characteristics of self-renewal and differentiation, the intracellular signaling pathways regulating self-renewal and differentiation of cancer stem cell include Wnt, Hedgehog signaling pathway.The tumor microenvironment is the dimensional environment surrounding the tumor,including the extracellular matrix, surrounding blood capillary,stromal cells ( fibroblasts, mesenchymal stem cells, tumor-associated endothelial cells, inflammatory cells) and cytokines secreted by stromal cells.Cancer stem cells maintain a close communication with the cells in the tumor microenvironment.In this paper, the cell surface maker of cancer stem cell,cancer stem cells and regulation of cytokine in the microenvironment,intracellular signaling pathways of cancer stem cells are reviewed to show complex regulatory networks in the tumor microenvironment.This review should help providing a new direction on specific cancer therapy for cancer stem cells in cacer treatment.
ABSTRACT
Objective@#To investigate the clinicopathologic characteristics of neoplastic cell-rich mixed cellularity classical Hodgkin lymphoma(MCCHL-R) and to compare the prognosis with typical mixed cellularity classic Hodgkin lymphoma(MCCHL).@*Methods@#Fifty-four patients with MCCHL-R(the tumor cells >10%) and 65 patients with typical MCCHL identified from 1 721 Hodgkin lymphomas were reviewed to compare the clinicopathological characteristics including morphologic and immunophenotypic features, EBV infection status, clinical therapy and overall survival.@*Results@#The median age of the patients of MCCHL-R was 28.5 years(range: 9-76 years, male∶female=1.6∶1.0). Twenty-seven patients(50.0%) had B symptoms. Most patients had cervical lymph node involvement(81.5%, 44/54). Mediastinum and spleen involvement were seen in 69.2%(36/54) and 24.1%(13/54), respectively. Extranodal non-lymphoid organ involvement was seen in 41.3%(19/46) cases. Morphologically, lymph node architectures were effaced at various degree with large neoplastic cells of variable morphology, including Hodgkin/Reed-Sternberg(H/RS) cells and anaplastic large cells. There were abundant background heterogeneous admixtures of non-neoplastic inflammatory and accessory cells that were predominant mature small lymphocytes. All tumors were positive for CD30 and weakly positive for PAX5. Epstein-Barr encoded RNA(EBER)detectable by in situ hybridization was seen in 39.0% cases. Forty-six patients had a median follow-up time of 32.5 months(range: 5-128 months) and the 5-year survival rate for stage Ⅰ-Ⅱ and stage Ⅲ-Ⅳ patients were 91.7% and 50.1%, respectively(P<0.05). The 5-year survival rate for MCCHL-R was lower than typical MCCHL patients. Single factor analysis showed that age of >45 years, extranodal involvement and stage Ⅲ-Ⅳ were correlated with poorer 5-year survival rate(P<0.05). Multiple factors Cox proportional hazards regression showed that extranodal involvement was the independent prognostic factor(RR: 4.352, 95%CI: 1.122-16.879, P<0.05).@*Conclusions@#MCCHL-R is more common in young people. The tumor has pathological features of classic Hodgkin lymphoma enriched with the tumor cells(>10%) and similar immunophenotype to classical Hodgkin lymphoma. Compared with typical MCCHL, extranodal disease is an independent prognostic factor of MCCHL-R.

ABSTRACT
Objective To explore the effect of different hemostatic methods on ovarian function in la-paroscopic ovarian endometriosis cyst enucleation. Methods 200 cases of stage I and II ovarian endometriosis cyst admitted to our hospital from Jan. 2012 to Apr. 2014 were selected. All patients underwent conventional la-paroscopic ovarian endometrial endometriosis cyst enucleation. According to intraoperative hemostasis methods, patients were divided into 3 groups: suture group (n=70), electric coagulation group (n=70), and ultrasonic scalpel group (n=60). Follicle-stimulating hormone (FSH) and antibody forming cells (AFC) on admission and at 1, 3, 6, and 12 months after surgery were recorded. Peak systolic blood flow of ovarian stromal artery (PSV) was also observed. Results FSH for all the three groups were improved compared with that on admission, and the difference had statistical significance (P0.05). however, AFC of the suture group at 3, 6, and 12 months after surgery was significantly im-proved compared with those of the the electric coagulation group and ultrasound knife group. The difference had statistical significance (P<0.05). Vaginal type B ultrasonic examination after operation showed that PSV of the su-ture group was higher than that of the electric coagulation group and ultrasound knife group at the second menstru-ation and at the 6-month menstruation after surgery. The difference of PSV between the 3 groups had statistical significance (P<0.05). Conclusion Compared electric coagulation hemostasis and ultrasonic scalpel hemostasis, the suture method can reduce damage of ovarian function in patients with ovarian endometriosis cyst, which is worth to promote.

The neoplastic T-cells expressed CD3 and CD5 and partly positive for CD10 and bcl-6, CD21 showed expanded and irregular follicular dendritic cell (FDC) meshworks that surrounding the high HEV. The HRS-like cells were positive for MUM-1 and Ki-67, variable intensity positive for CD30, CD20, and PAX-5, but negative for CD15. EBV-positive cells included HRS-like cells and small to large-sized neoplastic T-cells, which formed small clusters or scattering in the background of the disease.</p><p><b>CONCLUSIONS</b>The clinical course of angioimmunoblastic T-cell lymphoma with HRS-like cells is aggressive. Which present with histomorphology overlap with classical Hodgkin lymphoma (CHL), similar to CHL in EBER and immunophenotype, however, it is easy to misdiagnosis as HL. Thus, angioimmunoblastic T-cell lymphoma pathology diagnosis should comprehensive analysis of different kinds of materials, including clinical features, and histological structure, and EBER, and immunophenotype, and gene rearrangement.</p>

Objective To investigate CT and MRI imaging of Warthin tumor of parotid gland.Methods CT and MRI character-istics of 5 1 patients confirmed as Warthin tumor by operation and pathology were analyzed retrospectively.Results Among 5 1 cases, 43 patients were males,and 8 patients were females.A total of 84 lesions were found in all cases,20 cases had at least 2 lesions.The margins of lesions were well-defined.68 lesions were round or elliptical.45 lesions located in the posterior and inferior quadrant of the parotid gland completely or premodinantly.The density and signal of most lesions were homogeneous.The parenchymal area of most lesions showed an early moderate-remarkable enhancement.Small blood vessels surrounded the lesions in 1 9 cases.Conclusion CT and MRI are important and valuable for the diagnosis of Warthin tumor.
ABSTRACT
Objective:To statistics and analyze the detection rate of 5 kinds of common respiratory virus specific IgM in children with respiratory tract infection to guide the clinical.Methods: 1 609 cases of children with respiratory tract infection in department of Pediatrics in our hospital were collected in 2012 from 1 to 12 months.Serum was collected to detect the specific IgM of respiratory syncytial virus (RSV),adenovirus (ADV),influenza A virus (IVA),influenza B virus (IVB) and parainfluenza virus ( PIV) by method of indirect immunofluorescence.Results:263 positive cases were detected from 1 609 cases ( 16.35%) , and the positive rates of IVB was the highest (8.45%) with a total of 136 cases,followed by the rest of IVA 63 cases(3.92%),PIV 62 cases (3.85%),ADV 44 cases(2.73%) and RSV 42 cases(2.61%).The positive detection rate was different in children of different age groups,and the difference was statistical significant (χ2=134.822,P<0.01).Positive detection rate was gradually increased along with the age growth,and the detection rate of school-age children was the highest (34.55%);The comparison differences of IVB ,PIV,IVA positive detection rate between different age stages were significant (χ2=102.660 ,86.145 ,39.791 ,P<0.05 ).The detection rate of IVB and IVA was the highest in school-age children,20.00%and 8.64%respectively.The detection rate of PIV was the highest (12.07%) in preschool children.The positive rates of different respiratory virus specific IgM had their own characteristics in different months .IVB appeared two positive peaks in March and October with the rate of 20.15%and 11.11%respectively;IVA appeared two positive peaks in March and May with the rate of 10.27% and 11.81% respectively;PIV and RSV , the detection rate of which was the highest ( 7.98%and 6.46 respectively ) in March increased gently from January to June ,and then declined steadily.The detection rate of ADV was the highest (6.19%) during three months of March ,April and May.Conclusion:The positive rate of 5 kinds of respiratory virus specific IgM was 16.35%,especially the detection rate of IVB was the highest.Positive detection rate of respiratory virus specific IgM was gradually increased along with the age growth;The detection rate of IVB and IVA was the highest in school-age children ,while PIV in preschool children.5 kinds of respiratory tract virus own respectively prevalent characteristics in 2012.
