Objective To evaluate the efficacy of both domestically manufactured and imported recombinant human growth hormone (rhGH) in the treatment of growth hormone deficiency(GHD) disease. Methods 67 patients with GHD were given domestically manufactured rhGH ,while imported rhGH were given to another 19 boys with GHD. The dose of rhGH in both groups was 0 1IU?Kg -1 ?d -1 . 19 boys with GHD received imported rhGH for 24 months in combination with administration of chorionic gonadotropin or Testoviron Depot in second year. Vital Capacity (VC) and Maximal Ventilation Volume(MVV) before and 6,12 months after rhGH treatment were measured in 10 cases. Results The increase in linear growth was significant in both groups. In 19 boys with GHD, HA was direct proportion to BA before and 6,12,18,24 months after treatment. In 10 boys with GHD, 12 months after rhGH treatment, VC and MVV significantly increased as compared with pre-treatment (P

Objective To investigate the effect of cartoon video-assisted preoperative interview on the postoperative maladaptive behaviors of preschool pediatric patients.Methods One hundred preschool pediatric patients,aged 3-6 yr,weighing 12-28 kg,of American Society of Anesthesiologists physical status Ⅰ or Ⅱ,scheduled for elective strabismus surgery,were divided into 2 groups (n =50 each) using a random number table:cartoon video-assisted preoperative interview group (group Ⅰ) and routine preoperative interview group (group Ⅱ).In group Ⅰ,accompanied by the anesthesiologist,children and their parents watched the cartoon video designed for the perioperative process,and the anesthesiologist answered the questions that their parents had.After completion of tracheal intubation,dexmedetomidine 0.3 and 0.6 μg/kg were infused intravenously over 10 min in group Ⅰ and group Ⅱ,respectively.Three percent-4％ sevoflurane was inhaled to maintain anesthesia.The development and degree of agitation during stay in the post-anesthesia care unit (PACU) were recorded.The emergence time and length of PACU stay were also recorded.Postoperative maladaptive behaviors were assessed with the Post-Hospital Behavior Questionnaire at 1 week after surgery,and the occurrence of behavioral changes was recorded.Results Compared with group Ⅱ,the incidence of emergence agitation was significantly decreased,the degree of emergence agitation was reduced,the emergence time and length of PACU stay were shortened,and the incidence of behavioral changes (4％) was decreased after surgery in group Ⅰ (P＜0.05).Conclusion Cartoon video-assisted preoperative interview can effectively decrease the development of postoperative maladaptive behaviors of the preschool pediatric patients.

Objective To determine the likelihood of G-protein coupled receptor 56 (GPR56 ) induces axonal development and myelination in the corpus callosum of mouse brain.Methods A total of 64 Gpr56 +/-and Gpr56 -/-mice were selected and randomly divided into two groups:Gpr56 +/-group (n=32)and Gpr56 -/-group (n=32).According to number of days after birth,each group was further divided into 4 subgroups including P7d,P14d,P21d and P28d subgroups.Levels of neurofilament-200 (NF -200)and proteolipid protein (PLP ) of myelin basic protein in corpus callosum were measured with immunohistochemistry staining and Western blot in P7d、P14d、P21d、P28d Gpr56 +/- and Gpr56 -/-mice.Gpr56 +/-and Gpr56 -/-neurons were cultured using P1 d Gpr56 +/-and Gpr56 -/-mouse brain.The lengths of Gpr56 +/- and Gpr56 -/-neuronal axon were measured and compared with Image J software. Axonal myelination in the corpus callosum of mouse brain in each group was observed under electronic microscopy and the axonal diameters between subgroups were compared.Results The levels of NF-200 and PLP in the corpus callosum in P7d、P14d、P21d、P28d Gpr56 -/-mice decreased significantly compared with Gpr56 +/- mice.The length of Gpr56 -/-neuronal axon was shortened compared with Gpr56 +/-neuronal axon.The number of myelinated axons was obviously reduced in the corpus callosum in P28d Gpr56 -/-mice.The diameter of axon in the corpus callosum of P28d Gpr56 +/-mouse is longer than that of P28d Gpr56 -/-mouse. Conclusions GPR56 may be involved in axonal development and myelination in the corpus callosum of mouse brain.

Objective To study the expression of fragile histidine triad(FHIT) in oral squamous cell carcinoma(OSCC),and discuss its role and significance in OSCC.Methods Immunohistochemical method was used to detect the expressions of FHIT in 48 cases of OSCC and 26 normal oral mucosa.Results The positive expression rate of FHIT in normal oral mucosa was 76.92%(20/26).Among 48 OSCC patients,the positive rate of FHIT(43.75%) was lower than that in normal oral mucosa(P0.05),but FHIT protein content was significantly associated with differentiation(P

Background and purpose:The morbidity and mortality of lung cancer are currently the highest malignant tumor in China and the world. Most onset age of the illness is after 60 years old. Therefore, surgical resection of lung cancer in the elderly is very worthy of concern. This study aimed to investigate the clinical features, epidemic characteristics and conditions in perioperative period between the elderly and middle-aged patients with lung cancer, and provide the reference for clinical treatment.Methods:Totally 1 019 patients with lung cancer who were admitted to the hospital and accepted the operations in department of thoracic surgery in Shanghai Pulmonary Hospital from Jan. 2007 to Dec. 2012 were analysed retrospectively. The clinical data including gender, pathological type, TNM stage, intraoperative amount of bleeding and post-operative length of hospitalization were compared.Results:There was a signiifcant difference in sexual factors between these two groups (P?0.05), and compared with the middle-aged group, the proportion of male was more higher in the elderly group (76.91%vs 52.81%). Adenocarcinoma was the most common and squamous carcinoma was the next in both two groups. The constituent ratio of the pathlogical type between the elderly group and the middle-aged group was statistically signiifcant (P?0.05). The squamous carcinoma in the elderly group was higher than that in the middle-aged group (37.5%vs 15.6%). On the contrary, adenocarcinoma was more common in the middle-aged group (72.8%vs 50.7%). StagesⅡa,Ⅱb, andⅢa were more common in the elderly group and stagesⅠa, andⅠb were the most clinical stage in the middle-aged group. The clinical stage between two groups was statistically significant (P?0.05).The intraoperative amount of bleeding was higher and the post-operative length of hospitalization was longer in the elderly group, with a signiifcant difference as compared with that in the middle-aged group(P?0.05). And there was a signiifcant difference in incidence of accompanying diseases between the two groups, compared with the middle-aged group, the proportion of accompanying diseases was more higher in the elderly group(58.6%vs42.3%).Conclusion:Elderly patients with lung cancer are more common in males, with adenocarcinoma being the most common. The cancer mostly belongs to a medium or advanced stage. Elderly patients have the trend with more amount of bleeding in operation and lengh of stay.

Objective To assess the incidence and prognosis of the bronchial anastomosis complications following lung transplantation.Methods Between January 2003 and July 2016,all 81 cases after lung transplantation at Department of Thoracic Surgery of Shanghai Pulmonary Hospital,Tongji University were retrospectively analyzed.We analyzed the incidence and prognosis of postoperative complications of bronchial anastomosis in lung transplant recipients.Results The overall incidence of bronchial anastomotic complications was 30.9％,including anastomotic infection (18.5 ％),anastomotic fistula (4.9 ％),stenosis (6.2 ％),and bronchomalacia (1.2 ％).One case died of infection,and 3 cases died of anastomotic fistula.Conclusion The main bronchial anastomosis complications occurred early,and the prognosis was acceptable.

Objective To explore the advantages and disadvantages of helicopter emergency medical services of South China in the long-distance transport for critical patients.Methods A total of 30 patients who received helicopter emergency medical services by Guangdong Generral Hospital from August 2004 to December 2014 were selected as the observation group,and the other 30 patients with similar conditions who received ground emergency medical services were selected as the control group.To analyses the difference between the two groups in the disease,transport distance,transportation time,costs and compliction by χ2-test,t-test and nonparametric test according types of data.Results There were significantly difference between two groups in transport distances (km) [578.0 (313.0,707.5)vs.214.5 (101.5,313.5),P <0.05],set-up time (min) [95.7 (56.7,133.4)vs.10.7 (6.8,15.7),P <0.05],transportation time (min) [112.3 (64.3,152.4) vs.146.8 (67.8,217.5),P <0.05],costs (yuan/h) [14378.5 (9887.0,16348.5)vs.557.0 (356.5, 787.5),P <0.05]and the distance/total time value [2.8 (1.3,4.8)vs.1.4 (0.8,2.8),P <0.05]. There was no significantly difference in the incidence of complications between two groups (χ2 =0.058,P >0.05).Conclusions Helicopter emergency medical services could shorten the transportation time of critical patients on long distance transportation,and improve the efficiency of first-aid.However,there were many disadvantages that need to be improved in the helicopter emergency medical service of China.

Objective To investigate the differential diagnostic features of subtpes of renal cell carcinoma (RCC) using CT scan.Methods The CT appearances of 53 RCCs,including 28 clear cell RCCs (CCRCC),6 Xp11.2 /TFE RCCs (Xp11.2 /TFE RCC),7 collecting ducts RCCs (CDC),12 chromophobe RCCs (CRCC),were retrospectively analyzed and compared with finding of pathology.Dynamic contrast-enhanced CT (DCE-CT) was conducted in each case after intravenous administration of contrast agent,and the data was analyzed by AVONA and LSD text.Results On unenhanced and enhanced CT,most CCRCCs and CDCs showed heterogeneous density (23/28,6/7),with necrosis (21/28,6/7),and most Xp11.2/TFE RCCs,CRCCs showed homogeneous density(5/6,8/12).Most CCRCCs,Xp11.2/TFE RCCs and CRCCs had clearly boundaries with well demonstrated at enhanced CT delayed phase (25/28,6/6,10/12),CDCs had unclearly boundaries (6/7),and most CCRCCs had lymph node or other metastasis (19/28).A phenomenon of quick staining and quick fainting was observed in CCRCCs.Xp11.2/TFE RCCs,CDCs,CRCCs showed delayed enhancement.On unenhanced CT,the Xp11.2/TFE RCC attenuation was greater than CCRCC,CDC,CRCC and normal renal cortex (53.7±4.1 vs 45.8±3.6 vs 41.4±2.4 vs 47.7±3.6 vs 41.5±5.1,F=5.458,P＜0.01,respectively).The enhancement degree was highest for CCRCCs,lowest for CDCs,and intermediate for Xp1 1.2/TFE RCCs and CRCCs.The enhancement degree of Xp1 1.2/TFE RCC was higher than that of the CDC and CRCC (P＜ 0.01).The enhancement degree of Xp11.2/TFE RCC and CRCC were higher than that of the normal renal medulla at cortical and medullary phases (P＜0.01),but lower than that of the renal medulla on delayed phase (P＜0.01).The enhancement degree of CDC were lower than that of the normal renal cortex and medulla on cortical,medullary and delayed phases (P＜0.05).Conclusions CT could distinctly show imaging features of CCRCC,Xp1 1.2/TFE RCC,CDC and CRCC,which were related to their pathological characteristics,and these features were helpful in predicting a specific subtype of RCC.
