Objective To explore the feasibility of the ultrasonic atomization surface anesthesia with lido-caine for awake fiberoptic endotracheal intubation in patientsˊautonomous position -display before general anesthesia and to evaluate its advantages.Methods 68 adult patients who needed prone position for elective surgery under general anesthesia were selected and randomly divided into two groups,the control group and the treatment group,each group in 34 cases.In control group patients were received surface anesthesia of cricothyroid membrane puncture.In treatment group,nebulized 2% lidocaine with ultrasonic nebulizer was used for topical anesthesia.Patients lied in the prone position according to their own comfort with the guide of the medical staff in the waking state after an awake fiberoptic endotracheal intubation.The statistics of mean arterial pressure (MAP)and heart rate (HR)were recorded respectively in the basal state(T0),in the time instantly after intubations(T1 ),in the 3 minute after intubations(T2 ) and in the time instantly after the body turning(T3 ).Choking cough response were recorded during endotracheal intubation.Patients were asked the efficacy of surface anesthesia and the tolerance for awake intubation after operation.Results Patients in both two groups completed the whole process smoothly.MAP and HR had no signifi-cant differences between the two groups in the same time point (all P >0.05).There were no statistical significance between the two groups in choking cough response,the time of surface anesthesia and intubation,neither (all P >0.05).Conclusion The surface anesthesia with lidocaine by continuous ultrasonic atomizing inhalation is a good and simple method deserving generalization with plenty merits and is practicable for patients to display position autonomously. This method have the advantages of small operation,it will and can replace cricothyroid membrane puncture.

Objective The international multidisciplinary lung adenocarcinoma classification was published by IASLC/ ATS/ERS in 2011.This study aimed to explore the clinicopathologic characteristics of lung adenocarcinoma based on IASLC/ATS/ERS classification and validate its clinical diagnostic and therapeutic value.Methods 2 056 cases of surgical resection from Shanghai Chest Hospital were classified according to the new classification and clinical information were retrospectively reviewed.The clinicopathologic characteristics based on new classification were analyzed statistically.Results Our data indicated that women were in high risk of lung adenocarcinoma; The average age of onset was 59-year-old; the female patients were younger than the male patients (58.7 years vs 60.2 years,P ＜ 0.01) ; Average tumor diameter was 2.6 centimeter; right lung was more popular than left and superior lobe than the inferior one.Acinar predominant subtype and papillary predominant subtype were frequently observed.Micropapillary predominant subtype and solid predominant subtype were identified to be more aggressive than other histopathologic subtypes.Most patients were classified as stage Ⅰ(71.7％),which were predominantly stage Ⅰa (53.1％).Conclusion The new classification is superior to reflect the clinicopathologic characteristics of lung adenocarcinoma and satisfy clinical needs,especially contributing to change and update the surgical strategy of early stage lung adenocarcinoma.

Objective To explore the method and the clinical effects of surgical treatment for severe hedge brain injury at frontotemporal bottom. Methods 96 patients with severe hedge brain injury at frontotemporal bottom were scored by GOS before surgery. Then unilateral or bilateral craniotomy was carried out,via a large flap incision in the site of frontotemporal and parietal hair,and the blood clots within the surgical fieldand the inactivation brain tissue having been fell off were removed, and the contusion lesions of brain bottom were exposed, and the inactivation brain tissue was cleared. If the brain injury was serious ,the removal of frontal pole and temporal pole should be proper. Discretion to The removing or replacing the bone flap should be based on consideration of the circumstances. Six nonths or one year after injury,96 patients were scored by GOS again. Results There were 17 cases of grade Ⅰ(17.71%) ,11 cases of gradeⅡ (11.46%),13 cases of gradeⅢ (13.54%),21 cases of grade Ⅳ(21.86%),34 cases of grade Ⅴ (35.42%) in 96 patients. Conclusion Early surgical treatment of severe hedge brain injury at frontotemporal bottom could improve the cure rate and reduce the rate of disability.

Objective To evaluate the role of autophagy in hippocampal neurons in cognitive dysfunction caused by sevoflurane anesthesia in juvenile rats.Methods One hundred four male SpragueDawley rats, aged 7 days, weighing 10-16 g, were randomly assigned into 3 groups using a random number table: control group (group C, n =8), sevoflurane anesthesia group (group S, n =48), and sevoflurane anesthesia + rapamycin group (group SR, n =48).Group C inhaled 60％ oxygen for 6 h.S and SR groups inhaled 3.6％ sevoflurane anesthesia for 6 h, and in addition, rapamycin 2 mg/kg was injected intraperitoneally at 1 h before of sevoflurane inhalation in group SR.The equal volume of phosphate buffer solution was given in C and S groups.At 1 h before sevoflurane anesthesia (T0) , immediately after the end of anesthesia (T1) , and at 12, 24 and 48 h after the end of anesthesia (T2-4) , 8 rats were randomly selected from S and SR groups to determine the expression of autophagy-related proteins microtubule-associated protein 1 light chain 3 (LC3) Ⅰ , LC3 Ⅱ and Beclin-1 in hippocampal neurons (by Western blot).The ratio of LC3 Ⅱ/LC3 Ⅰ was calculated.Morris water maze test was performed at 5 weeks after the end of anesthesia to assess the cognitive function.The escape latency, frequency of crossing the original platform, and duration of swimming spent at the target quadrant were recorded.Results Compared with the values at T0, the expression of LC3 Ⅱ and Beclin-1 was significantly down-regulated at T1-3 , and the ratio of LC3 Ⅱ/LC3 [was decreased in group S, and the expression of LC3 Ⅱ and Beclin-1 was significantly up-regulated at T1-4, and the ratio of LC3 Ⅱ/LC3 Ⅰ was increased in group SR (P＜0.05).Compared with group C, the escape latency was significantly prolonged, the frequency of crossing the original platform was reduced, and the duration of swimming spent at the target quadrant was shortened at 3-5 days in group S (P＜0.05) , and no significant change was found in the parameters mentioned above in group SR (P＞ 0.05).Compared with group S, the escape latency was significantly shortened, the frequency of crossing the original platform was increased, and the duration of swimming spent at the target quadrant was prolonged at 3-5 days, the expression of LC3 Ⅱ and Beclin-1 was up-regulated at T1-4 , and the ratio of LC3 Ⅱ/LC3Ⅰ was increased in group SR (P＜0.05).Conclusion Weakened autophagy in hippocampal neurons is involved in cognitive dysfunction caused by sevoflurane anesthesia in the juvenile rats.

OBJECTIVETo observe the effect of purgation and detoxification therapy on gastrointestinal dysfunction of critically ill patients undergoing abdominal surgery.

METHODSTotally 56 inpatients with severe gastrointestinal dysfunction after abdominal surgery at ICU of Guangdong Provincial Hospital of Traditional Chinese Medicine were assigned to the treatment group and the control group, 28 in each group. All patients received routine Western medical treatment. Patients in the treatment group additionally took Modified Huanglian Jiedu Decoction (MHJD) and received electroacupuncture (EA) for 7 days. The first exhaust time, defecation time, scores for gastrointestinal dysfunction, mechanical ventilation time, ICU hospitalization time, and 28-day fatality rate were observed. Furthermore, serum levels of diamine oxidase (DAO) and D-lactic acid were detected at day 1, 3, and 7 after treatment.

RESULTSThe first exhaust time and the first defecation time in the treatment group were ahead of schedule, when compared with those of the control group (P <0. 05). Scores for gastrointestinal dysfunction, mechanical ventilation time, serum levels of DAO obviously decreased in the treatment group (P <0. 05). There was no statistical difference in serum levels of D-lactic acid, ICU stay time, the incidence of pulmonary infection, and 28-day mortality between the two groups (P >0. 05). Results of Logistic analysis showed that scores for gastrointestinal dysfunction were related with the incidence of pulmonary infection (P <0. 05).

CONCLUSIONMHJD combined EA could promote the recovery of gastrointestinal function in critically ill patients after abdominal surgery via improving intestinal barrier function, which was benefit for shortening mechanical ventilation time.

Objective To impmve the method of "modified comet assay" in predicting the radiosensitivitv of solid tumor. Methods A single cell suspension from biopsy sample was lmdlated on ice with a dose of 5 Gy.The microscope slide was spread with agarose,lysed for 50 minutes,rinsed 3 times rinse solution,and given electrophoresis for 20 minutes. After being stained with PI,cell images were collected through the microscope and analyzed with Lucia G software(Version 4.6).In order to check system/ background errors,every sample was made into control slide and irradiation slide.The end-points were cell DNA contents and tail moment. Results The factors influencing the results included:(1)Sample was iaulty tor the biopsv taken from mucosa and no tumor cells were contained. (2)The slides with a high backgmund ( induced by necrosis) disturbed the measurement of comet assay. (3) Setting lymphocytes as control to check svstem errors was very important. (4)To separately collect images of the normal tissue cells and tumor cells from the biopsy sample improved the conformity between the clinical obscrvation and the lab result. Conclusions To increase the correlation between comet assay and clinical response,it is very helpful to set double control for checking system/background errors and to collect images of the normal tissue cells and tumor cells through the microscope,respectively.

A 28-year-old female patient presented with indurated erythema and nodules on the right lower limb for 2 years,with mild itching and pain.Skin examination showed a well-circumscribed irregular dark red patch measuring about 10 cm × 5 cm in size on the extensor aspect of the right thigh.On the patch,there were scattered or densely distributed mung bean-to soybean-sized quasi-circular violaceous nodules with a smooth surface,which were hard on palpation.Subcutaneous nodules with medium hardness were found on palpation,and hyperpigmentation was observed on the surface of some nodules.Local skin temperature was increased,with tenderness on palpation.Histopathologically,mononuclear cells showed nodular or sheet-like distribution in the middle and upper dermis,some of which had pale-staining cytoplasm.Moreover,plenty of plasma cells were observed.Immunohistochemistry revealed that histiocytes were stained strongly positive for S100.The number of IgG4-positive plasma cells increased obviously,and was more than 50 per high-power field (× 200).The proportion of IgG4-positive plasma cells in IgG-positive plasma cells was 45％.Finally,the patient was diagnosed with cutaneous Rosai-Dorfman disease with increased IgG4-positive plasma cells.
