OBJECTIVE: To achieve targeted and meticulous surgery of adenoid hypertrophy, a comprehensive analysis of adenoid hypertrophy space occupying effect and morphological evaluation were conducted and the clinical results were retrospectively analyzed. METHOD: One hundred and sixty-three children with adenoid hypertrophy were treated in our department from May 2013 to May 2014. All children received three examinations preoperatively, including: Nasopharyngo-fiberoscopy, Audiometry and Tympanometry. Based on the results, space occupying effect of adenoid hypertrophy was divided into three types: vertical hypertrophy type, horizontal hypertrophy type and vertical & horizontal hypertrophy type. We assumed the causal relationship with vertical hypertrophy type to snoring (nasal blockage) and horizontal hypertrophy type to secretory otitis media respectively. All children received transoral endoscopic adenoidectomy with radiofrequency ablation. RESULT: The postoperative followup of these children for 6 to 12 months showed that the vertical hypertrophy type and horizontal hypertrophy type children all recovered from the syndromes of snoring (nasal blockage) and secretory otitis media respectively. The nasopharyngo-fiberoscopy showed that the nasopharyngeal space was smooth and the bilateral choanas opened well. No recurrence was found. CONCLUSION The philosophy of comprehensive analysis on adenoid hypertrophy space occupying effect could help the surgeons understand adenoid hypertrophy better and can guide the adenoidectomy more meticulously.

The use of tyrosine kinase inhibitor imatinib in treatment of gastrointestinal stromal tumors(GISTs)has achieved a dramatic therapeutic efficacy. However,secondary imatinib resistance emerged as a clinical problem needs to be solved urgently. The underlying mechanisms of GISTs secondary resistance to imatinib may be related with secondary mutations of KIT/ PDGFRA genes,loss of PTEN gene and induction of cellular quiescence. This resulted in the adoption of new therapeutic strategies such as novel tyrosine kinase inhibitors,combined use of imatinib with downstream signaling inhibitors,KIT/ PDGFRA independent targeted inhibitors such as KIT chaperone inhibitors and aurora kinase inhibitors,as well as inducing apoptosis in quiescent GIST cells. In this article,the above-mentioned issues were summarized.

OBJECTIVE: To investigate the efficacy of submucosal resection by CO2 laser in the treatment of recurrent laryngeal papilloma and the effect on prognosis. METHOD: A total of 11 patients diagnosed as recurrent laryngeal papilloma were included in this review. Papilloma was marked before operation and checked under fibro-laryngoscope. Papilloma was resected completely including the submucosal tissure with CO2 laser or microequipment. In widespread papilloma, false membrane in raw surface were cleared 7-10 days after operation. Surgical specimens (including membrane) were detected by routine pathology, HPV typing and immunohistochemical pathologic examination. The patients were checked once a month in the first 3 months after operation, and then once for every 3 months. Once the hoarseness and other symptoms aggravated or the disease was recurrent, the patients were treated immediately. RESULT: HPV viral DNA was found in 10/11 cases, with HPV11 (7/11 cases) and HPV6 (3/11 cases). Cases with regards to follow-up, from 6 months to 1 year, 3 cases were followed up 1 year after operation, without recurrence. Five patients including 2 children were followed up 6 to 12 months after operation, without recurrence. Two children underwent 2 or 3 operations, were followed-up more than 6 months withouting recurrence. CONCLUSION Papilloma submucosal resection could decrease postoperative recurrence and is worth to be further investigated.

OBJECTIVE: To investigate the possibility of thyroidectomy/lobectomy without drainage after surgery. METHOD: Eighty-eight consecutive cases with thyroid mass have been underwent operations including: lobectomy group(42 cases), thyroid lobectomy with contralateral partial thyroidectomy group (17 cases) and total thyroidectomy group (29 cases) from 2013. 06 to 2014. 06 in Nanjing Tongren Hospital. FIfteen patients with thyroid operation in other hospital were collected from 2014. 01 to 2014. 06, the recovery of postoperative incision were compared. RESULTS: Eighty-four cases were smoothly discharged from hospital except 4 thyroidectomy cases suffered from a small amount of effusion in surgical cavity. Our postoperative wound recovery were more in line with the principle of cosmetology compared with other hospital operation group. CONCLUSION Drainage following thyroidectomy is not essential, if the thyroid surgery is meticulous in each step of the surgery, and can increase the effect of beauty.

OBJECTIVE: To study the spontaneous rehabilitation and phonation quality of vocal cords after different types of CO2 laser microsurgery. METHOD: Surgical procedures based on Remacle system Type I, Type II, Type III, Type IV and Type V a respectively. Three hundred and fifteen cases with hoarseness based on strobe laryngoscopy results were prospectively assigned to different group according to vocal lesions apperence,vocal vibration and imaging of larynx CT/MRI. Each group holded 63 cases. The investigation included the vocal cords morphological features,the patients' subjective feelings and objective results of vocal cords. RESULT: There are no severe complications for all patients in perioperative period. Vocal scar found in Type I ,1 case; Type II, 9 cases ;Type III, 47 cases; Type IV, 61 cases and Type Va 63 cases respectively after surgery. The difference of Vocal scar formation after surgery between surgical procedures are statistical significance (χ2 = 222.24, P < 0.05). Hoarseness improved after the surgery in 59 cases of Type I , 51 cases of Type II, 43 cases of Type III, 21 cases of Type IV and 17 cases of Type Va. There are statistically significance (χ2 = 89.46, P < 0.05) between different surgical procedures. The parameters of strobe laryngoscope: there are statistical significance on jitter between procedures (F 44.51, P < 0.05), but without difference within Type I and Type II (P > 0.05). This happened in shimmer parameter and the maximum phonation time (MPT) as jitter. There are no statistical significance between Type IV and Type Va on MPT (P > 0.05). CONCLUSION Morphological and functional rehabilitation of vocal cord will be affected obviously when the body layer is injured. The depth and range of the CO2 laser microsurgery are the key factors affecting the vocal rehabilitation.

Objective To establish a new model of acute hepatic failure in canines for bioartificial liver treatment research . Methods Acute hepatic failure was induced by end to side portocaval shunt combined with common bile duct ligation and transection. The survival rate, liver function, ammonia, Fischer's ratio (BCAA/AAA) and pathological change of injury liver were investigated. Results The ammonia, ALT, AKP, total bilirubin and PT were elevated dramatically and Fischer's ratio declined significantly 14 days after the operation. The survival rate of the models decreased with time 14 days after the operation. Pathological examination of liver tissues revealed evidence of cholestasis, inflammation with accumulation of neutrophils, degeneration and necrosis of hepatocytes.Conclusions End to side portocaval shunt combined with common bile duct ligation and transection can produce a satisfactory acute hepatic failure model in canines, which could be used in the study of bioartificial liver.

OBJECTIVE To study the clinical features of acute leukemia(AL) patients with complication of infection. METHODS A retrospective analysis of prevalence of infection occurring in 123 AL patients,their bacterial spectrum,and the effect of G-CSF on the infection were done. RESULTS The prevalence of infection in AL patients was 94.3%,among which 49.2% were infected with Gram-positive organisms,42.4% with Gram-negative bacilli and 8.4% with fungi.Blood culture occurred mostly with Escherichia coli and Pseudomonas infection.Patient′s neutropenia was significantly related to the infection.The patients with neutrophil count less than 0.2?10~9/L had more frequently suffered severe infection with long-lasting time,and had more than two sites of infection.Age,hemoglobin level,prophylactic intestinal usage of antibiotics could not reduce patient′s infection.The total mortality of AL patients with infection was 6%.Pulmonary infection and septicemia increased mortality,but G-CSF therapy reduced it. CONCLUSIONS AL patients are at high risk of infection which is significantly associated with severe neutropenia.G-CSF therapy exerts an assistant role to antibiotics in controlling the infection.

Objects: To investigate the behavior of gastric electrical activity in patients with gastrointestinal stromal tumor(GIST) to identify the influences of GIST on the normal gastric electrical activity. Methods: The electrogastrogram (EGG) parameters of 27 patients with gastric GIST (GIST group) and 30 healthy volunteers (control group) were detected by the multi-channel electrogastrogram and the data were analyzed. Results: The values of postprandial mean frequency (MF), mean amplitude (MA) and the percentage of normal slow wave (N%) were increased, and the percentage of bradygastria (B%) was decreased than those of the fasting in control group(P < 0.05 or P < 0.01). However, those postprandial parameter changes were not found in GIST group(P > 0.05). Compared with control group, the fasting MF and MA increased, the fasting N% of lead 1, 3, 4 and postprandial N% decreased, both percentages of fasting and postprandial tachygastria (T%) increased in GIST group (P < 0.01). The tachygastria incidence was significantly higher in GIST group than that of control (66.7% vs 3.3%, P <0.05). Conclusion: The gastric electrical activity was affected by the existence of GIST. The abnormal gastric electrical rhythm displayed mainly as tachygastria.
