Objective To investigate the distribution characteristics of the Epstein-Barr virus (EBV)in lymphomas.Methods 438 cases of lymphomas were reclassified according to the WHO classification of lymphoma (2008).ALK1,CD3,CD5,CD7,CD10,CD15,CD20,CD23,CD30,CD43,CD56,CD68,CD79,CD99,CyclinD1,EMA,IgD,TdT,Vs38C and LMP-1 were detected by in situ hybridization of EBER and immunohistochemistry.Results In B cell lymphoma,T and NK cell lymphoma and Hodgkin' s lymphoma (HL),the positive rates of EBER were 5.4 ％ (14/261),16.5 ％ (19/115) and 59.7 ％ (37/62),respectively,and the positive rates of LMP-1 were 5.4 ％ (14/261),5.2 ％ (6/115) and 59.7 ％ (37/62).In DLBCL patients,EBER expression in the older group was significantly higher than that in the younger one [13.2 ％ (7/53) vs 1.2 ％ (1/81),P ＜ 0.05].The expression of EBER and LMP-1 were inconsistent in T and NK cell lymphomas,and the positive rate of EBER was significantly higher than that of LMP-1 (P ＜ 0.05).EBER was all positive in 5 cases of NK/T cell lymphoma-nasal type.The expression of EBER and LMP-1 were consistent in HL.Conclusion The EBV infection was associated with the classification of the lymphoma.The EBV infection was the highest in NK/T cell lymphoma-nasal type,and the next was in HL.Due to the consistency of EBER and LMP-1 expression in the HL,economically,LMP-1 may replace EBER as the indicator of EBV.EBV might play an important role in the occurrence and development of NK/T cell lymphoma-nasal type,HL and so on.

Objective To observe the therapeutic effect of abdominal acupuncture combined with Chinese medicine for the treatment of functional constipation. Methods Ninety-three qi-deficiency functional constipation patients were evenly randomized into western medicine group, Chinese medicine group and combination group. The western medicine group was given oral use of Dupbalac, Chinese medicine group was given modified Buzhong Yiqi decoction, and the combination group was given abdominal acupuncture and oral use of modified Buzhong Yiqi decoction. The treatment of the three groups covered 3 months. After treatment, the therapeutic effect was evaluated accord ing to the symptom scores and the examination results of gastrointestinal kinetics. Results ( 1) The total effective rate for relieving symptoms was 100.00% in combination group, 90.32% in Chinese medicine group, and 38.71% in western medicine group, and the effect was the best in the combination group ( P<0.05). ( 2) The combination group had stronger effect on relieving dyskinesis of anal sphincter, rectal sensibility, colonic transportation than Chinese medicine group and western medicine group (P<0.05). Conclusion Abdominal acupuncture combined with Chinese medicine shows certain therapeutic effect for the treatment of qi-deficiency functional constipation, and the effect is superior to that of Chinese medicine or Dupbalac.

OBJECTIVETo evaluate the orthopedic effect of presurgical nasoalveolar molding (PNAM) devices on the palatal deformities in unilateral complete cleft lip and palate (UCCLP) patients.

METHODSThree groups with 19 patients each were studied. All samples in groups A and B were non-syndromic UCCLP children. Group A was treated with PNAM prior to operation. Group B was untreated prior to operation. Samples in group C were normally developed nose and lip palate infants aged three months. The orthotopic palate photos before and after PNAM treatment for group A, as well as pre-operative photos of groups B and group C, were taken and measured. All statistics were analyzed using SPSS 21.0.

RESULTSPNAM treatment significantly increased the AW, AC, and PA of UCCLP patients (P < 0.05), whereas CPW, CWA, CWAS, CWAH, PMD, and CA significantly decreased (P < 0.05). However, no significant difference was observed with the cases in group C (P < 0.05). The AW, CPW, CA, and PA of the patients in group B significantly increased compared with the cases in group A before PNAM treatment (P < 0.05). Multivariate analysis of variance indicated that TW had no statistically significant difference among the three groups (P > 0.05).

CONCLUSIONPNAM treatment is a non-surgical early treatment for the effective improvement of palatal primary deformities in UCCLP patients.

Objective To investigate the diagnositc value of high frequency ultrasound guided fine needle aspirates (FNA) and thyroglobulin (Tg) in fine-needle aspirate fluid (FNA-Tg) measurement for detecting metastatic lymph nodes in patients underwent thyroidectomy for papillary thyroid carcinoma (PTC).Methods Sixty-five patients with 79 suspected metastatic lymph nodes were retrospective analysis in this study.FNA for suspected lymph nodes was performed guided by high frequency ultrasound and FNATg was measured.The histopathologic diagnosis for all of the suspected lymph nodes was obtained after lymphadenectomy.Results By histopathologic diagnosis,62 lymph nodes were positive metastasis,while 17 were negative metastasis.Fifty-four lymph nodes were diagnosed as positive metastasis and 25 as negative metastasis by FNA.The accuracy,sensitivity,specificity,positive predictive value and negative predictive value of FNA for assessing cervical metastatic lymph nodes from PTC were 89.87％ (71/79),87.10％ (54/62),100％ (17/17),100％ (54/54) and 68.00％ (17/25),respectively.Sixty-five lymph nodes were diagnosed as positive metastasis and 14 as negative metastasis by FNA-Tg.The accuracy,sensitivity,specificity,positive predictive value and negative predictive value of FNA-Tg were 96.20％ (76/79),100％ (62/62),82.35％ (14/17),95.38％ (62/65) and 100％ (14/14),respectively.There was no significant difference between FNA and FNA-Tg for evaluating cervical metastatic lymph nodes from PTC (x2 =1.454,P =0.228).Eight positive metastatic lymph nodes which were missed by FNA were corrected diagnosed by FNA-Tg measurement.Conclusions Both FNA and FNA-Tg are effective methods for assessing cervical metastatic lymph nodes from PTC postoperatively,and these two methods could be combined for early and accurate evaluating the lymph nodes state.

Objective During last decades,mechanical ventilation has been an important support in the postoperative management of patients undergoing cardiac surgery.However,a considerable number of patients need mechanical ventilation for a prolonged period after cardiac surgery,and this is associated with increased mortality and morbidity.The study was designed to determine the pre-and perioperative predictors of prolonged mechanical ventilation (PMV) in adult patients undergoing double valve surgery.Methods The retrospective study considered of 2026 adult patients who underwent double valve replacement surgery at Changhai Heart Center from January 1990 to December 2010.PMV is considered as mechanical ventilation period of ＞ 48 hours at postoperative hospital stay here.Results PMV occurred in 11.35 ％ of patients.The total hospital mortality was 4％.The hospital mortality of patients who had undergone double valve replacement surgery required PMV was significantly higher than control (33.5％ vs 0.2％,P ＜ 0.01).And so as comorbidities.Age more than 60 years (OR =1.943),diabetes(OR =1.757),preoperative active endocarditis (OR =3.167),New York Heart Association class higher than 3 (OR =2.464),preoperative critical state(OR =2.556),ejection fraction less than 0.50 (OR =2.026),creatinine greater than 110 μmol/L (OR =2.740),cardiopulmonary bypass time longer than 180 min (OR =3.529) and perioperative intra-aortic balloon pump(OR =18.350) were independent predictors of PMV in our patients.Conclusion PMV is associated with significant comorbidities and increased hospital mortality.Strategies to delineate the patients at risk and to modify these risk factors by prophylactic measures should probably lead to a lower incidence of prolonged mechanical ventilation for adult patients undergoing double valve replacement surgery.

Objective To establish a surgical risk prediction model for in-hospital mortality of adult rheumatic heart disease.Methods The study sample comprised of 3 889 patients with adult (is, or older than 18 years) rheumatic heart valve surgery only.All patients were divided into three subgroups according to the surgery site of left atrioventricular valve: mitral valve surgery group;aortic valve surgery group;and mitral and aortic valve surgery group.The data was splited into development(60％) and validation(40％) data sets, and then the risk model was developed by using a logistic regression model according to the data in development data set.Model calibration was analyzed by Hosmer-Lemeshow goodness-of-fit statistic, and model discrimination was tested by calculating the area under the receiver operating characteristic(ROC) curve.Risk score was finally set up according to the coefficient β and rank of variables in logistic regression model.Results The general in-hospital mortality of the whole group is 4.2％ (165/3 889).We established a risk prediction model and found seven risk factors: heart function in NYHA functional class ≥ Ⅱ grade (OR =3.36, 95％ CI: 2.42-4.67) , preoperative creatinine ＞ 110 mmoL/L (OR =2.69, 95％ CI: 1.51-4.79) , history of previous chest pain(OR =2.33, 95％ CI: 1.07-5.11) , surgical status(OR =2.32, 95 ％ CI: 0.94-5.73) , previous history of hypertension (OR =2.24, 95 ％ CI: 1.19-4.23), preoperative critical state (OR =2.14, 95％ CI: 1.27-3.60) and age ＞ 50 years (OR =1.57, 95 ％ CI: 1.18-2.09).Our risk model showed good calibration and discriminative power for the development data set, validation data set, and three subgroup in which Hosmer-Leme-show test' s P value were greater than 0.05 and the area under the ROC curve were greater than 0.70.Scoring methods: age 51-60years: 1 point, age 61-70 yeas: 2 points, age ＞70 years: 3 points;history of hypertension: 1 point;creatinine ＞ 110 umol/L: 4 points;NYHA class stage Ⅱ : 2 points, NYHA class stage Ⅲ: 4 points;NYHA class stage Ⅳ: 6 points;history of previous chest pain: 1point;preoperative critical condition: 2 points;urgent surgery: 2 points: emergency surgery: 4 points.Conclusion We have created a new risk prediction model and risk score, which can accurately predicts outcomes in patients undergoing heart valve surgery for our center.Furthermore, our risk model can also enable benchmarking and comparisons between multicenter in a meaningful way in the future.

Objective　To identify human gastric cancer related genes. Methods　Specimens of paired tumor, paratumor and normal gastric mucosa tissues were collected from five patients (male 3, female 2, with average age 48.8±18.1 years) who suffered from stomach antrum adenocarcinoma. Total RNA samples were extracted from these specimens, then studied by fluorescent differential display reverse transcription polymerase chain reaction (DDRT-PCR) analysis. The differentially expressed bands of interest were recovered, purified and cloned, then they were analyzed by sequencing, Northern blot and RT-PCR. Through BLAST, the sequencing results were compared with GenBank database for homology analysis.Results　One of the interesting cDNA bands expressed much lower in all five tested tumor samples than in their normal and paratumor counterparts. This band was named W4. Northern blot analysis showed a consistent result with that of DDRT-PCR. W4 was cloned into pGEM-T easy vector. Sequence analysis showed that W4 consists of 712bp, this sequence was named W44.BLAST analysis revealed that W44 has extremely low sequence identity with any genes from GenBank and any sequences from EST database. This sequence data was submitted to GenBank with accession No. AF150631. RT-PCR analysis showed that W4 was expressed much lower in 11/15 gastric cancer tissue than in paratumor and normal samples. Conclusion　A novel cDNA sequence related to human stomach adenocarcinoma was identified.

Objective:To explore the characteristics of nursing-related research design types, implementation organizations, funding sources and research fields by analyzing the characteristics of nursing-related trials registered in the Chinese Clinical Trial Registry (ChiCTR) .Methods:We searched the nursing-related clinical trials registered in the ChiCTR database, and the search time was from the establishment of the database to May 25, 2020. The characteristics of registered nursing related trials were analyzed.Results:A total of 319 nursing-related trials were obtained, of which 268 trials were registered as pre-registration and 51 trials were supplementary registration. The number of trial registrations in Shanghai, Guangdong, Sichuan, Jiangsu and Beijing were greater than or equal to 25. The main source of funding was college funds, followed by local finance, self-financing and national finance. Among the registered trials, 239 (74.92%) were randomized controlled trials, and 27 were multi-center clinical trials, and 53 trials used the blind method, and 277 trials passed the review of the ethics committee. Research fields were widely distributed, mainly tumors, strokes and diabetes.Conclusions:The number of nursing-related trials registered in ChiCTR is increasing, but there are regional imbalances in the distribution of research, and the low proportion of funding from high-level funds. Relevant personnel are needed to improve the level of nursing research from many aspects such as nursing education, nursing management, research registration management and funding support.
