Objective: To analyze the factors affecting the complication of pulmonary atelectasis among children with tracheobronchial tuberculosis (TBTB), so as to provide the reference for the prevention and treatment of pulmonary atelectasis complicated by TBTB. Methods: Children with TBTB admitted to Department of Paediatrics, Linping Division of the Second Affiliated Hospital of Zhejiang University School of Medicine were selected as the study subjects from October 2018 to March 2023. Subjects's basic information, etiological examination results and laboratory testing results were collected using a self-designed questionnaire, and factors affecting the complication of pulmonary atelectasis among children with TBTB were identified using a multivariable logistic regression model. Results: A total of 120 children with TBTB were included, with the age of 6 months to 12 years. There were 33 children at ages of less than one year (27.50%), 71 girls (59.17%) and 25 children with TBTB and pulmonary atelectasis (20.83%). Multivariable logistic regression analysis identified less than one year of age (OR=1.720, 95%CI: 1.126-3.358), type Ⅵ of TBTB (OR=1.669, 95%CI: 1.101-2.236), high level of C-reactive protein (OR=1.887, 95%CI: 1.088-2.686) and high level of procalcitonin (OR=1.844, 95%CI: 1.034-2.654) as risk factors for the complication of pulmonary atelectasis in children with TBTB. Conclusion Less than one year of age, type Ⅵ of TBTB, high level of C-reactive protein and high level of procalcitonin may increase the risk of pulmonary atelectasis in children with TBTB.

Objective To study the relationship of insulin-like growth factor-Ⅰ receptor(IGF-ⅠR)and carcinogenesis of gastric cancer.Methods The expression of IGF-ⅠR was detected in 40 cases of resected gastric cancer tissues and adjacent normal gastric mucosa by immunohistochemistry.The expression of IGF-ⅠR in gastric cancer cell lines(MGC803 and SGC7901)was detected by Western Blot.siRNAs targeted to IGF-ⅠR were designed,synthesized and transfected into MGC803 cells,the changes of IGF-IR protein level were detected by Western Blot at 48 h after transfection,the cell proliferation was examined by MTT,and then the growth curve was obtained.Results The positive rate of IGF-IR expression in gastric cancer tissues was 75.5%,significantly higher than that of adjacent normal tissues (25%,P＜0.01).The expression level of IGF-IR was related with TNM stage,lymphnode metastasis (P＜0.05),but not related with sex,age,histological differentiation,invasion depth of gastric cancer (P＞0.05).Intense expression of IGF-ⅠR was showed in gastric cancer cell lines.The inhibition ratio of IGF-ⅠR expression in sigNAl group were 89.80%±4.10%,the cell proliferation decreased to mininlunl level at the fifth day aftertransfection(by 29.0%±4.0%of mock-treated group),the cell number decreased by 21.15%±1.10%of mock treated group at the same time.Conclusions IGF-ⅠR is over-expressed in gastric cancer cells and can be effectively silenced by RNA interferes,therefore the growth of tmnor cell Was inhibited.Thus,it indicates that IGF-ⅠR may be a promising target for gene therapy of gastric cancer.

We developed a rehabilitation system by using the virtual reality technique and the Kinect in this paper. The system combines rehabilitation training with HMI and serious game organically, and provides a game and motion database to meet different patients' demands. Extended interface of game database is provided in two ways: personalized games can be developed by Virtools and Flash games which are suitable for patients' rehabilitation can be download from the Internet directly. In addition, the system provides patients with flexible interaction and easy control mode, and also presents real time data recording. An objective and subjective evaluation method is proposed to review the effectiveness of the rehabilitation training. According to the results of short questionnaires and the evaluation results of patients' rehabilitation training, the system compared with traditional rehabilitation can record and analyze the training data, which is useful to make rehabilitation plans. More entertainment and lower cost will increase patients' motivation, which helps to increase the rehabilitation effectiveness.

Objective To investigate the relationship between intra-abdominal fat area(IAFA)in male with abdominal obesity and glycometabolism related indicators. Methods Ninety-four obesity males,aged from 21 to 62 years old,were selected as our subjects. They were divided into abdominal obesity group(n = 70)and non-abdominal obesity group( n = 24). The general information of all subjects was recorded. The indexes of height,weight,waist circumference,hip circumference,body mass index(BMI)were measured. The fasting oral glucose tolerance test was performed. The levels of blood glucose(0,1,2 h)and insulin(0,1,2 h)were measured,and insulin resistance index was calculated. MRI measurement was applied to calculate the IAFA. Compared the difference between the two groups in term of the level of blood glucose,insulin and insulin resistance index,and analyzed the correlation between glycometabolism related indicators and IAFA. Results BMI,waist circumference,hip circumference,insulin resistance index and IAFA in abdominal obesity group were (28. 67 ± 4. 20)kg/ m2 ,(99. 75 ± 4. 07)cm,(104. 42 ± 7. 62)cm,2. 60 ± 1. 80,(153. 06 ± 53. 23)cm2 respectively,higher than those in non-abdominal obesity group((21. 80 ± 1. 97)kg/ m2 ,(79. 50 ± 10. 05)cm, (91. 86 ± 4. 49)cm,1. 52 ± 0. 73,(71. 78 ± 25. 48)cm2 ),and the differences were statistically significant(t= - 7. 704,- 9. 583,- 7. 618,- 2. 877,- 7. 184,P < 0. 05). The level of blood glucose at 0,1,2 h of patient in abdominal obesity group were(5. 89 ± 1. 36)mmol/ L,(10. 55 ± 3. 07)mmol/ L,and(8. 41 ± 3. 63) mmol/ L,higher than that in non-abdominal obesity group((5. 29 ± 0. 53)mmol/ L,(8. 76 ± 1. 96)mmol/ L, (6. 54 ± 1. 50)mmol/ L). Meanwhile,The insulin at 0,1,2 h of man in abdominal obesity group were(9. 71 ± 5. 05)mU/ L,(83. 29 ± 64. 51)mU/ L,(63. 56 ± 21. 09)mU/ L),significantly higher than those in non-abdominal obesity group((6. 42 ± 2. 96)mU/ L,(33. 00 ± 19. 82)mU/ L,(63. 56 ± 21. 09)mU/ L),and the differences were significant( t = - 2. 098,- 2. 671;- 2. 447,- 3. 010;- 3. 784,- 3. 089;P < 0. 05). The IAFA in abdominal obesity was positively correlated with age,BMI,waist circumference,hip circumference,blood glucose(0,1,2 h)insulin(0,2 h)and insulin resistance index(r = 0. 254,0. 533,0. 521,0. 615,0. 245,0. 315, 0. 294,0273,0. 249,0. 225,P < 0. 05 ). After adjustment for confounding factors,age( x1 ),abdominal circumference(x2)and insulin resistance index(x3)were related to IAFA(y = 1. 369x1 + 4. 472x2 + 25. 072x3- 333. 626). Conclusion Compared with patients with non-abdominal obesity,the IAFA of patient with abdominal obesity with abdominal fat area size is associated with insulin resistance.

Objective To investigate the clinical value of the combined detection of Golgi protein 73 (GP73),alpha-fetoprotein variant-L3 (AFP-L3)and transforming growth factorβ1(TGFβ1)in the early diagnosis of hepatocellular carcinoma (HCC).Meth-ods 48 cases of healthy control,42 cases of hepatitis B,50 cases of posthepatitic cirrhosis and 58 cases of HCC were selected and detected GP73,AFP-L3 and TGFβ1.The detection results were compared among 4 groups.Results (1)The levels of GP73,AFP-L3 and TGFβ1 had statistical differences among 4 groups(P <0.05 );(2 )The positive rate of the 3-marker combined detection reached 96.55%,which was higher than that of the 2-marker combined detection and the single marker detection.Conclusion (1) GP73,AFP-L3 and TGFβ1 may be used as the serum indicators for the early diagnosis of HCC;(2)Compared with the traditional HCC marker AFP,AFP-L3 has relatively high sensitivity and specificity and has the important role in the differential diagnosis of benign and malignant diseases of the liver,which is considered as a better serum marker in the HCC diagnosis;(3)The 3-indicator combined detection can significantly improve the positive detection rate of HCC and has better application value.

Objective To compare the clinical efficacy and safety of isotretinoin erythromycin gel, a gel containing isotretinoin (0.05%) and erythromycin (2%), versus adapalene gel in the treatment of mild to moderate acne vulgaris. Methods A multicenter, randomized, open, parallel-controlled clinical study was conducted. A total of 192 patients with mild to moderate (Grade Ⅰ -Ⅲ ) acne vulgaris were enrolled in this study according to the grading criteria for acne severity in guidelines for the treatment of acne in China. Efficacy analysis was carried out in 169 patients and safety analysis in 190 patients. The patients were classified into trial group (n = 86) and control group (n = 83 ) to be treated with isotretinoin erythromycin gel or adapalene gel once a night for 6 weeks. Patients were evaluated at the baseline, on week 2, 4 and 6 during the treatment for the count of comedones (both open and closed), inflammatory papules and pustules, severity of acne and local or general adverse effects. Results After the start of treatment, the response rate gradually increased and severity of acne decreased in both groups. On week 6, the total response rate was 51.16% in the trial group and 40.96% in the control group (P ＞ 0.05), while a greater reduction in the count of pustules and inflammatory lesions was observed on week 4 and 6 in the trial group with a lower severity grade of acne compared with the control group (P ＜ 0.05 or 0.01 ). Adverse reactions were similar in both groups and manifested as tolerable local irritation. Conclusions The efficacy of isotretinoin erythromycin gel is similar to that of adapalene gel in the treatment of mild to moderate acne vulgaris, however, isotretinoin erythromycin gel seems superior to adapalene gel in reducing inflammatory lesions and rapidly improving severity of acne vulgaris.

Objective To explore the pain beliefs and perceptions held by patients with digestive system cancer.Methods 10 patients with digestive system cancer were interviewed for exploration of their pain beliefs and perceptions.The data were collected using in-depth interview and analyzed with category approach.Results The beliefs and perceptions held by patients with digestive system cancer were presented as:negative pain beliefs,negative emotional perceptions,view social support as important resources.Conclusions The pain beliefs and perceptions in digestive system cancer pain patients are negative.Clinical medical workers should pay attention to the role of beliefs in pain management,and help patients build positive pain beliefs through utilizing social support resources effectively.

Objective To retrospectively analyze the clinical epidemiology features of adult idiopathic membranous nephropathy (IMN) in Zhongshan Hospital,and to investigate their therapeutic effect and its possible influence factors.Methods A total of 183 patients admitted to the Zhongshan Hospital of Fudan University and diagnosed as IMN by renal biopsy from January 2013 to December 2015 were involved.Their baseline information including demographics and pathologic was collected.Patients were followed up for at least 12 months.Serum albumin ＜ 30 g/L and 24 h urine protein ＞ 3.5g were defined as nephrotic syndrome (NS).IMN patients were divided into NS and non-NS groups and compared.Furthermore,the baseline data of remission and no remission patients were compared,and the correlations of their baseline data with conservative and immunosuppressive therapy were assessed by logistic regression analysis.Results (1) IMN accounted for 11.1％ of renal biopsy cases in our hospital,with an average age of 57 years and 59.6％ male patients.(2) Compared with patients without NS,IMN patients with NS were older,had a shorter time from the onset to receive renal biopsy,lower estimated glomerular filtration rate,and higher total cholesterol,low density lipoprotein cholesterol,triglyceride and serum creatinine (all P ＜ 0.05).(3) The effective rate of conservative treatment in IMN patients without NS was 65.7％,and the ineffective group had higher triglyceride compared with the effective group (P=0.019).(4) The effective rate of immunosuppressive therapy in IMN patients with NS was 81.2％,and low serum albumin was an independent risk factor for the poor efficacy of immunosuppressive therapy (OR=1.202,95％ CI 1.003-1.440,P=0.046).(5) The effective rate of conservative treatment in IMN patients with NS was 55.5％,and low serum albumin was an independent risk factor for the poor efficacy of conservative treatment (OR=1.629,95％CI 1.047-2.536,P=0.023).Conclusions The detection rate of IMN is increasing year by year,but the remission rate of conservative treatment is still not low in mild and moderate patients.For the patients without NS,high triglyceride may predict a poor effect of conservative treatment.Hypoproteinemia is a predictor of poor effect,no matter what a NS patient takes immunosuppressive therapy or conservative treatment.

Objective:To evaluate the protective immunity by vaccination of BALB/c mice with rLV-HA-GCN4,a recombinant lentivirus expressing the trimeric HA of swine H1N1 influenza virus. Methods:The female mice were randomly divided into rLV-HA-GCN4,rLV-HA,LV and PBS groups. Mice were primed with plasmid and boosted with lentivirus by the administration of intramuscular thigh injections at an interval of two weeks. At day 28 post-prime immunization,mice were inoculated intranasally with 100TCID50 of swine H1N1 influenza virus in a 50 μl volume. The immune levels were assessed by the T lymphocyte transformation test, flow cytometry,indirect ELISA and the indexes of spleen and lung. Results:The spleen lymphocyte transformation rate was 0. 3±0. 11 in the rLV-HA-GCN4 group at day 14 post-boost immunization, showing a statistical significance ( P<0. 01 ) compared to the PBS group. Meanwhile,rLV-HA-GCN4 could cause T lymphocyte response mainly based on the Th1-type CD4+ T cells. The IgG antibody titer reached to 1:8 000 at day 14 post-boost immunization and approximately 1:7 000 at day 14 post challenge. After challenge,the spleen and lung indexes of rLV-HA-GCN4 group were significantly lower than those of PBS group (P<0. 05). The body weight of rLV-HA-GCN4 group demonstrated a slight decrease before 3 days post challenge and then a gradual increase compared to the LV and PBS groups (P<0. 05). Conclusion:rLV-HA-GCN4 can effectively induce cellular and humoral immune response in BALB/c mice against swine H1N1 influenza virus.
