Objective To explore the effects of recombinant human growth hormone(rh-GH) on immune function in children with tetralogy of Fallot (TOF) after radical operation. Methods Thirty children with TOF were divided into two groups: conventional (n=20) and rh-GH (n=10, 0.2U/kg rhGH, sc., three times per week for 4 weeks). The immunoglobulin, complement fraction, lymphocyte subsets, and interleukins were determined. Results After treatment, the abnormal elevation of IgG, IgM, C_3, C_4, CD8~+ and CD19~+ in rhGH group decreased significantly at 1 week to 3 weeks; moreover, the abnormal descend of IgA, CD3~+, CD4~+, CD4~+/CD8~+, CD3~+/HLA-DR~+, and CD3~+/CD~ (16+56) in rh-GH group increased significantly at 1 week to 2 weeks compared to those of conventional group; and all recovered to the levels of control at 4 weeks. The interleukin-6 and tumor necrosis factor-? levels in the plasma and supernatant of peripheral blood mononuclearcytes decreased gradually at 1 week to 2 weeks after treatment compared to those of conventional group, and also recovered to the levels of control at 4 weeks. Conclusion rh-GH therapy could significantly improve immune function of children with TOF after radical operation.

Objective To evaluate the significance of detecting plasma methylated Septin9 (SEPT9) alone and combined with fecal immunochemical test (FIT) in screening colorectal cancer (CRC) and adenoma.Methods From October 2014 to April 2015,outpatients received CRC and adenoma screening were enrolled.Colonscopy examination and pathological diagnosis were taken as gold standard.The sensitivity and specificity of plasma methylated SEPT9 and FIT in CRC and adenoma were calculated.The diagnostic value of combined examination was evaluated.Receiver operating characteristic (ROC) curve of SEPT9 in CRC diagnosis was drawn.Results A total of 300 outpatients were enrolled.Among them,CRC was detected in 45 patients (15.0％) and adenoma was detected in 68(22.7％) patients,including 37(12.3％) cases of advanced adenomas.The sensitivity of SEPT9 and FIT for CRC diagnosis was 80.0％ and 88.9％,and the specificity was 95.3 ％ and 54.1％,respectively.The area under concentration curve (AUC) of methylated SEPT9 in CRC diagnosis was 0.923.The sensitivity of SEPT9 and FIT in advanced adenoma diagnosis were 10.8％ and 62.2％,and the specificity were 83.3％ and 49.0％,respectively.The sensitivity of combined examination in CRC diagnosis was 97.8％ and the specificity was 52.9％;the sensitivity in advanced adenoma diagnosis was 67.6％ and the specificity was 47.4％.Conclusions Plasma methylated SEPT9 is helpful in CRC screening,moreover,when combined with FIT,it can increase detection rate of colorectal adenoma.

Objective:To discuss the significance of standardized treatment for cancer pain, according to the Cancer Pain Treat-ment Specification (2011 Edition) issued by the Ministry of Health, PR China. Methods:Clinical data of 126 patients with cancer pain, who were admitted to the Department of Medical Oncology, The Fourth Hospital of Hebei Medical University, were collected to com-pare the improvement of the Numeric Rating Scale (NRS) score, number of breakthrough pain, and quality of life score after treatment. The relationships between different pain grades, disease entities, and treatment effect were analyzed. The influence factors of pain relief were also analyzed by using Logistic regression analysis. Results:1). Following standardized treatment, the improvement rate of NRS score has shown significant differences in pain grading (P=0.001) and gender (P=0.000). However, no significant differences were ob-served between different diseases (P=0.112). The improvement rate of the life quality score and the number of breakthrough pain had no significant difference after standardized treatment. 2). The grading of cancer pain and the disease entities had little effect on cancer pain relief. 3). The anti-tumor treatment and“no distant metastasis”were the independent factors that brought about the decrease in NRS and quality of life scores.“No distant metastasis”(P=0.046) was the independent factor that reduced the number of pain out-breaks. Conclusion: The standardized treatment positively affects the NRS score, number of breakthrough pain, and quality of life score. Patients who received anti-neoplastic therapy and who had no distant metastasis showed significant treatment effectiveness in pain management.

OBJECTIVE:To investigate the compatible stability of Calcium folinate for injection mixed with Glucose injection and Sodium chloride injection. METHODS:Referring to clinical common concentration,each 3 Calcium folinate for injection (each injection was equal to calcium folinate 100 mg)were respectively mixed with Glucose injection 250 mL or Sodium chloride injection 250 mL. At room temperature,under light or dark condition,the appearance of mixtures,pH value and the number of in-soluble particles were investigated 0,1,2,3,4,6,8,12,24,36,48 h. The contents of calcium folinate in mixtures were deter-mined by HPLC. RESULTS:Under above condition,the color of the mixtures had no change,and no gas,precipitation and turbid-ity was found;there was no evident change in pH values(RSD<2%,n=11). 0 h after mixing,there was large number of parti-cles≥10 μm in mixtures,but the number of particle was decreased as time;within 48 h,the number of particles ≥10 μm and ≥25 μm in mixtures were all in line with the standard of Chinese Pharmacopeia(2015 edition). Under the protection from light con-dition,relative contents of calcium folinate in mixtures had no significant change(RSD<2%,n=11). Under light condition,rela-tive contents of calcium folinate in mixtures decreased significantly,decreasing to 94.5%(mixed with Glucose injection) and 88.4%(mixed with Sodium chloride injection). CONCLUSIONS:Calcium folinate for injection is more stable in Glucose injec-tion,and the stability of compatibility can be affected by light conditions. After mixed with Glucose injection and Sodium chloride injection,Calcium folinate for injection should be kept away from light and used as soon as possible

AIM: To survey the pathogenesis, clinical characteristics and surgical treatment for the correction of A-pattern exotropia.METHODS: The case history and surgical effect of 62 A-pattern exotropia in 1825 strabismus were studied. The superior oblique muscles weakening or the horizontal muscles procedures were performed in all patients according to the dysfunction of the superior oblique muscles, horizontal deviation, with or without binocular vision. Follow-up after surgery was 6-18months with mean duration of 9 months.RESULTS: A-pattern exotropia accounts for 3.4% of all strabismus. A-pattern exotropia accounts for 21.2% of A-V syndrome. After surgery, 52 cases got alignment, 56 cases gained A-sign correction and 54 cases recovered binocular vision.CONCLUSION: A-pattern exotropia is a common type in strabismus, its etiology is mainly oblique muscle dysfunction.Different surgical procedures should be selected according to overaction degrees of oblique muscle and binocular vision function, which can acquire the satisfied results.

OBJECTIVE: To investigate whether the allergic factors impact the severity of chronic rhinosinusitis or not, further more, to explore the relationship between allergic rhinitis and chronic rhinosinusitis. METHOD: A retrospective review was done on 103 patients. All of these patients were under functional intranasal endoscopic sinus surgery after expectant treatment is ineffective. We devided the patients into different groups according to the result of skin prick and specific IgE and if there is difference in VAS score, Lund and Kennedy endoscopic score, Lund-Mackay CT score between the groups. We also analysed the symptoms in different chronic rhinosinusitis patients allerged to variant kinds of allergen. The SPSS 17.0 software was used to analyze the data. Statistical analysis was performed by t-test, rank order test or χ2 test. RESULT: The duration of the disease, VAS score of nasal blockage, score of Lund-Mackay CT and Lund and Kennedy endoscopic before the operation were in no statistical sense after when compared with the two groups of patients with chronic rhiriosinusitis who grouped according the result of skin prick and specific IgE. The VAS score of facial pressure and loss of smell was higher in patients with chronic rhinosinusitis which the skin prick and specific IgE were positive. The VAS score of nasal discharge was higher in patients with chronic rhinosinusitis who got negative skin prick and specific IgE result. The symptoms of chronic rhinosinusitis improved with operation no matter the group of skin prick and specific IgE positive or negative and VAS score of nasal blockage improved significantly in negative group. The symptoms of sneezing, rhinorrhoea and rhinocnesmus improved after operation among the chronic rhinosinusitis patients with skin prick and specific IgE. The number of cockroach allergy is larger among the patients with chronic rhinosinusitis without polyps than the one among the patients with chronic rhinosinusitis with polyps. CONCLUSION Allergic factor didn't impact much the severity of chronic rhinosinusitis patients who were failed in expectant treatment, besidesthe postoperative outcomes showed that only influence the severity of nasal discharge, facial pressure and loss of smell. Different kinds of allergen were found between the patients of chronic rhinosinusitis with or without polyps. No significantly functional endoscopic sinusitis sugrery outcome were related to the allergic factor. But the allergic factor may interfere the remission of nasal discharge after surgery.
