Objective: To evaluate the immunogenicity of group A+C meningococcal polysaccharide conjugate vaccine in infants under 2 years old. Methods: From March 2017 to June 2018, 1 932 healthy infants in Biyang County, Henan Province, who were not vaccinated with meningococcal meningitis vaccine and whose axillary temperature was ≤37.0 ℃, were recruited as participants. The 3 months and 6-11 months old infants were allocated to the experiment group and the control group in a ratio of 1∶1. Infants aged 12-23 months were allocated to the 1-dose group, the 2-dose group and the control group in a ratio of 1∶1∶1, with 276 infants in each group. The infants in the experiment group were intramuscularly injected with freeze-dried group A+C meningococcal polysaccharide conjugate vaccine to be evaluated, and infants in the control group received intramuscular injection of commercially available freeze-dried group A+C meningococcal conjugate vaccine. The venous blood of infants was collected 30 days before the first dose and after the last dose of inoculation, and the antibody seroconversion of each group was determined and compared. Results: The completion rate of immunogenicity study was 95.2% (1 839/1 932). Before inoculation, there was no statistical difference in the geometric mean titer and positive rate of group A+C antibodies between the experiment group and the control group in 3 months and 6-11 months old infants (all P values >0.05). The geometric mean titers and positive rate of group A antibodies in the 1-dose group were higher than those in the control group (all P values <0.05), but there was no statistical difference between the 2-dose group and the control group (all P values >0.05) in infants aged 12-23 months. After inoculation, the differences (95%CI) in the positive conversion rate of group A+C antibodies between the experiment group and the control group were -0.12% (-6.01%-5.77%) and 0.82% (-4.23%-5.86%) in the 3 months old infants. At the age of 6-11 months, the differences were 6.75% (1.71%-11.79%) and -4.32% (-8.73%-0.08%), respectively. At the age of 12-23 months, the differences were 1.02% (-3.80%-5.83%) and -4.40% (-7.79%- -1.01%) in the 2-dose group and -7.22% (-12.90%- -1.54%) and -18.61% (-23.75%- -13.46%) in the 1-dose group, respectively. The geometric mean titers of group A+C antibodies in the 3 months old infants were 48.50 and 63.12, respectively, which had no significant difference from the control group (43.02 and 57.99, respectively) (both P values <0.05). The geometric mean titers of group A+C antibodies in the 6-11 months and 12-23 months old infants were 84.09 and 92.51 (2-dose group), which were higher than those in the corresponding control group (43.10 and 61.83, respectively) (all P values <0.001). Conclusion: Group A+C meningococcal conjugate vaccine has good immunogenicity in infants under 2 years old.

A 57-year-old male patient was referred to our department with complaints of his right adrenal gland occupancy and hypertension about 6 months. When admitted to the hospital, the blood pressure was about 160/100 mmHg, and the heart rate was 110 beats/min. He was no obvious obesity, acne, abnormal mood, without weakness of limbs, acral numbness, palpitation and headache. He presented with type 2 diabetes for more than 3 years, with oral administration of metformin enteric coated tablets and subcutaneous injection of insulin glargine to control blood glucose, and satisfied with blood glucose control. Enhanced CT showed that: the right adrenal gland showed a kind of oval isodense, slightly hypodense shadow, the edge was clear, lobular change, the size was about 5.8 cm×5.4 cm, uneven density, there were nodular and strip calcification, round lipid containing area and strip low density area, and the CT value of solid part was about 34 HU. Enhanced scan showed heterogeneous nodular enhancement in the solid part of the right adrenal gland, nodular enhancement could be seen inside. The CT values of solid part in arterial phase, venous phase and delayed phase were 45 HU, 50 HU and 81 HU, respectively. Considering from the right adrenal gland, cortical cancer was more likely. No obvious abnormality was found in his endocrine examination. After adequate preoperative preparation, retroperitoneal laparoscopic adrenalectomy was performed under general anesthesia. During the operation, the 6 cm adrenal tumor was closely related to the inferior vena cava and liver, and after careful separation, the tumor was completely removed and normal adrenal tissue was preserved. The operation lasted 180 min and the blood loss was 100 mL, and the blood pressure was stable during and after the operation. There was no obvious complication. The results of pathological examinations were as follows: the size of the tumor was 7.5 cm×6.0 cm×3.5 cm, soft, with intact capsule and grayish-red cystic in section. Pathological diagnosis: (right adrenal gland) cavernous hemangioma, secondary intravascular thrombosis, old hemorrhagic infarction with calcification and ossification. After 6 months of observation, no obvious complications and tumor recurrence were found. In summary, cavernous hemangioma of adrenal gland is a rare histopathological change. Its essence is a malformed vascular mass. Blood retention is the cause of thrombosis and calcification in malformed vessels. The imaging findings were inhomogeneous enhancement of soft tissue masses, and the adrenal function examination showed no obvious abnormalities. Retroperitoneal laparoscopic surgery is feasible after adequate preoperative preparation. It is difficult to diagnose the disease preoperatively and needs to be confirmed by postoperative pathology.

OBJECTIVE: To investigate the nutritional status of children with cerebral palsy (CP) and the clinical effectiveness of Subjective Global Nutritional Assessment (SGNA) in nutritional assessment of hospitalized children with CP. METHODS: A total of 208 children with CP, aged 1-5 years, who were hospitalized from April to October 2019 were enrolled as subjects. SGNA was used to investigate nutritional status, and the Z-score method recommended by the World Health Organization was used as a reference standard to validate the clinical effectiveness of SGNA. RESULTS: The detection rate of malnutrition in children with CP was 42.3% by SGNA and 39.4% by the Z-score method (P>0.05). The application of SGNA showed high consistency between different evaluators (κ=0.621, P<0.001). With the Z-score method as the reference standard, SGNA had a sensitivity of 80.5%, a specificity of 82.5%, a positive predictive value of 75.0%, and a negative predictive value of 86.7%, and high consistency was observed between the two evaluation methods (κ=0.622, P<0.001). SGNA was moderately consistent with weight-for-age Z-score and height-for-age Z-score (κ=0.495 and 0.478 respectively, P<0.001) and was poorly consistent with weight-for-height Z-score (κ=0.197, P<0.05). CONCLUSIONS There is a relatively high incidence rate of malnutrition in children with CP. SGNA can be used as a tool to assess the nutritional status of children with CP.

OBJECTIVE: To compare the accuracy of three methods for measuring the length of both lower limbs in hip arthroplasty for femoral neck fracture in the elderly, and to introduce a "shoulder to shoulder" anatomical location marking method for femur. METHODS: From January 2017 to January 2019, 90 elderly patients with femoral neck fracture were treated with hip replacement, including 39 males and 51 females, aged 65 to 96(78.0±7.4) years, 56 cases of total hip and 34 cases of hemi hip. According to garden classification, there were 7 cases of typeⅡ, 63 cases of type Ⅲ and 20 cases of type Ⅳ. The patients were divided into three groups according to different measurement methods:contralateral contrast method (group A) of 19 cases, shuck test method (group B) of 28 cases, and "shoulder to shoulder" anatomical marker localization method (Group C) of 43 cases. The accuracy of the three methods was compared by measuring the length difference of lower limbs in vitro and imaging. RESULTS: All patients completed the operation successfully. After total hip arthroplasty, the length of lower limbs in group A was(12.9±8.6) mm, and that in group B was(10.3±4.4) mm. After hemiarthroplasty, the length of lower limbs in group A was (13.2±7.2) mm, group B was (8.7±3.5) mm, and group C was (6.3±2.8) mm; the measurement results of unequal length of lower limbs after total hip arthroplasty were(12.9±8.1) mm in group A, (9.6±4.0) mm in group B and (6.6±2.6) mm in group C. The results of factorial analysis of variance showed that the differences among the three groups were statistically significant ( CONCLUSION The "shoulder to shoulder" anatomic localization marking method can reduce the length of lower limbs simply, effectively and accurately in the elderly patients with femoral neck fracture hip replacement.

Background:Clinical outcomes of undifferentiated arthritis (UA) are diverse,and only 40 ％ of patients with UA develop rheumatoid arthritis (RA) after 3 years.Discovering predictive markers at disease onset for further intervention is critical.Therefore,our objective was to analyze the clinical outcomes of UA and ascertain the predictors for RA development.Methods:We performed a prospective,multi-center study from January 2013 to October 2016 among Chinese patients diagnosed with UA in 22 tertiary-care hospitals.Clinical and serological parameters were obtained at recruitment.Follow-up was undertaken in all patients every 12 weeks for 2 years.Predictive factors of disease progression were identified using multivariate Cox proportional hazards regression.Results:A total of 234 patients were recruited in this study,and 17 (7.3％) patients failed to follow up during the study.Among the 217 patients who completed the study,83 (38.2％) patients went into remission.UA patients who developed RA had a higher rheumatoid factor (RF)-positivity (42.9％ vs.16.8％,x2=8.228,P=0.008),anti-cyclic citrullinated peptide (CCP) antibodypositivity (66.7％ vs.10.7％,x2 =43.897,P ＜ 0.001),and double-positivity rate of RF and anti-CCP antibody (38.1％ vs.4.1％,x2 =32.131,P ＜ 0.001) than those who did not.Anti-CCP antibody but not RF was an independent predictor for RA development (hazard ratio 18.017,95％ confidence interval:5.803-55.938;P ＜ 0.001).Conclusion:As an independent predictor of RA,anti-CCP antibody should be tested at disease onset in all patients with UA.

Objective: To investigate the characteristics of acute myocardial infarction caused by spontaneous coronary artery dissection(SCAD) in young female patients. Methods: In this casecontrolstudy,127 young(≤55 years) female patients with acute myocardial infarction onset within 1 week in Nanjing first hospital, Xuzhou central hospital, affiliated hospital of Xuzhou medical university, and Lianyungang first people's hospital were enrolled between January 2013 and February 2017,and the clinical data were retrospectively analyzed. According to their clinical manifestations and coronary angiography(CAG) results,the patients were divided into coronary atherosclerosis disease(CAD) group(CAG evidenced atherosclerosis, n=83) and SCAD group(CAG detected coronary artery dissection,n=44).The SCAD patients were subdivided into definite group (the results affirmed from intravenous ultrasound or optical coherence tomography, n=21) and probable group (the CAG results highly confirmed to characteristics of SCAD,but no intravenous ultrasound or optical coherence tomography image affirmation,n=23). Then, according to the different treatment strategies, the SCAD patients were subdivided into conservative treatment group(treated with drugs,n=19) and interventional therapy group(treated with percutaneous coronary intervention,n=25). Results: (1)Compared to CAD group, patients in the SCAD group had less risk factors, such as hypertension history (25.0% (11/44) vs. 45.8% (38/83) , P=0.022) and diabetes history (6.8% (3/44) vs. 21.7% (18/83) , P=0.043),and had lower levels of fasting blood glucose (5.34(4.59,5.87) mmol/L vs. 7.12(5.18,8.60)mmol/L, P=0.001),total cholesterol((3.94±1.14) mmol/L vs. (4.91±1.50) mmol/L, P=0.001),triglyceride(1.42 (0.91,1.64) mmol/L vs. 1.89 (1.23,2.45) mmol/L, P=0.005),and low density lipoprotein cholesterol ((2.24±0.91) mmol/L vs. (2.94±1.16) mmol/L, P=0.001),CAG results showed that patients in the SCAD group had more single vessel lesion (88.6% (39/44) vs. 39.8% (33/83) , P=0.001), and their target lesion stenosis was less severe ( (79.2±22.4) % vs. (91.5±12.1) %, P=0.001). (2) The clinical risk factors such as hypertension history, diabetes history, smoking history, family history of cardiology disease, fasting blood glucose,total cholesterol,triglyceride and low density lipoprotein cholesterol were similar between definite group and probable group (all P>0.05). CAG results showed that prevalence of single vessel lesion (100% (21/21) vs. 78.3% (18/23) , P=0.050) and percent of target lesion stenosis ( (76.9±20.6) % vs. (81.2±24.1) %, P=0.529) were similar between definite group and probable group.(3)There were no significant difference in single vessel(84.0% (21/25) vs. 94.7% (18/19) , P=0.370), target lesion stenosis(85.0(70.0,100.0)% vs. 75.0(50.0,90.0)%, P=0.186),and survival rates in hospital(96.0% (24/25) vs. 100% (19/19) , P=1.000) between interventional therapy group and conservative treatment group. Conclusions Prevalence of SCAD is highin young female patients with acute myocardial infarction. Acute myocardial infarction patients with less risk factors of CAD and with CAG showing smooth lesion of narrowing segment and normal finding in the other vessels, are more likely to be diagnosed with SCAD.Acute myocardial infarction patients caused by SCAD have high survival rate either receiving percutaneous coronary intervention or drug treatment.

Objective To evaluate the value of the three-dimensional visualization technology for the preoperative assessment of liver autotransplantation for end-stage hepatic alveolar echinococcosis. Methods A total of 8 patients with end-stage hepatic alveolar echinococcosis undergoing liver autotransplantation in Qinghai Provincial People’s Hospital from May 2013 to July 2017 were collected. All cases received preoperative abdominal CT scanning and dynamic three-phase enhanced CT scanning, and the original CT data were transferred to the human 3D visualization virtual surgical planning system. The volumes of Echinococcus multilocularis and pre-resected liver were measured using the 3D visualization reconstruction, and the relationship between the lesion and the neighboring tissues was observed. The value of the 3D visualization technology for the preoperative assessment of liver autotransplantation for end-stage hepatic alveolar echinococcosis was assessed by comparing with the intraoperative findings. Results The 3D visualization reconstruction model clearly displayed the adjacent relationship between the lesions of end-stage hepatic alveolar echinococcosis and the neighboring tissues, and no significant difference was seen between the pre-resected liver volume in 3D visualization reconstruction model and the actually resected liver volume (t = 1.083, P > 0.05). Conclusions 3D visualization technology is feasible to develop a reasonable scheme for liver resection and vascular anastomosis for end-stage hepatic alveolar echinococcosis prior to liver autotransplantation, which may increase the success of surgery and improve the prognosis.

Background:For Chinese patients with hepatocellular carcinoma (HCC),surgical resection is the most important treatment to achieve long-term survival for patients with an early-stage tumor,and yet the prognosis after surgery is diverse.We aimed to construct a scoring system (Shanghai Score) for individualized prognosis estimation and adjuvant treatment evaluation.Methods:A multivariate Cox proportional hazards model was constructed based on 4166 HCC patients undergoing resection during 2001-2008 at Zhongshan Hospital.Age,hepatitis B surface antigen,hepatitis B e antigen,partial thromboplastin time,total bilirubin,alkaline phosphatase,γ-glutamyltransferase,α-fetoprotein,tumor size,cirrhosis,vascular invasion,differentiation,encapsulation,and tumor number were finally retained by a backward step-down selection process with the Akaike information criterion.The Harrell's concordance index (C-index) was used to measure model performance.Shanghai Score is calculated by summing the products of the 14 variable values times each variable's corresponding regression coefficient.Totally 1978 patients from Zhongshan Hospital undergoing resection during 2009-2012,808 patients from Eastern Hepatobiliary Surgery Hospital during 2008-2010,and 244 patients from Tianjin Medical University Cancer Hospital during 2010-2011 were enrolled as external validation cohorts.Shanghai Score was also implied in evaluating adjuvant treatment choices based on propensity score matching analysis.Results:Shanghai Score showed good calibration and discrimination in postsurgical HCC patients.The bootstrap-corrected C-index (confidence interval [CI]) was 0.74 for overall survival (OS) and 0.68 for recurrence-free survival (RFS) in derivation cohort (4166 patients),and in the three independent validation cohorts,the CIs for OS ranged 0.70-0.72 and that for RFS ranged 0.63-0.68.Furthermore,Shanghai Score provided evaluation for adjuvant treatment choices (transcatheter arterial chemoembolization or interferon-α).The identified subset of patients at low risk could be ideal candidates for curative surgery,and subsets of patients at moderate or high risk could be recommended with possible adjuvant therapies after surgery.Finally,a web server with individualized outcome prediction and treatment recommendation was constructed.Conclusions:Based on the largest cohort up to date,we established Shanghai Score-an individualized outcome prediction system specifically designed for Chinese HCC patients after surgery.The Shanghai Score web server provides an easily accessible tool to stratify the prognosis of patients undergoing liver resection for HCC.

OBJECTIVETo establish questionnaire scaling and reliability and examine the clinical and psychometric validity of the quality of life assessment based on Traditional Chinese Medicine for advanced gastric cancer (QLASTCM-Ga).

METHODSThe QLASTCM-Ga was developed based on programmed decision procedures with multiple nominal and focus group discussions, in-depth interview, pretesting and quantitative statistical procedures. The questionnaire was administered to 240 patients diagnosed with advanced gastric cancer before and after treatment. Structured group methods were employed to establish a general and a specifific module respectively. The psychometric properties of the scale were evaluated with respect to validity, reliability and responsiveness.

RESULTSThe three identified scales of the QLASTCM-Ga and the total score demonstrated good psychometric properties. Test-retest reliability of the total scale and all domains ranged from 0.90 to 0.94, and internal consistency ranged from 0.86 to 0.93. Correlation and factor analysis demonstrated good construct validity. Signifificant difference in the subscales and the total score were found among groups differing in traditional Chinese medicine syndrome, supporting the clinical sensitivity of the QLASTCM-Ga. Statistically signifificant changes were found for each scale and the total score. Responsiveness was also good.

CONCLUSIONSThe QLASTCM-Ga demonstrates good psychometric and clinical validity to assess quality of life in patients with advanced gastric cancer undergoing traditional Chinese medicine therapy. This study is an important fifirst step for future research in this area.

Locally advanced pancreatic cancer is associated with a very poor prognosis. This study was performed to evaluate whether patients with locally advanced pancreatic cancer benefit from (125)I seed implantation. This retrospective study included 224 patients with locally advanced pancreatic cancer, with 137 patients (61.2%) in the implantation (IP) group and 87 (38.9%) in the non-implantation (NIP) group. The survival status, complications and objective curative effects were compared between the groups. The average operative time in the IP group was significantly longer than that in the NIP group (243±51 vs. 214±77 min). The tumor response rates were 9.5% and 0 at the 2nd month after surgery in the IP and NIP groups, respectively (P<0.05). The IP group exhibited a trend toward pain relief at the 6th month after surgery. The global health status scores of the IP group were higher than those of the NIP group at the 3rd and 6th month after surgery. The median survival time in the IP group was significantly longer than that in the NIP group. In conclusion, patients with locally advanced pancreatic cancer can benefit from (125)I seed implantation in terms of local tumor control, survival time, pain relief and quality of life.
