ABSTRACT
Objective:To investigate the application effects of self-developed rapid tracheotomy apparatus for acute tracheotomy.Methods:A total of 120 patients who underwent an acute tracheotomy in the Weihai Branch of The 970 Hospital of PLA Joint Logistics Support Force from January 2019 to December 2020 were included in this study. These patients were randomly divided into a rapid group and a conventional group, with 60 patients in each group. Patients in the rapid group underwent tracheotomy with a self-developed rapid tracheotomy apparatus. Patients in the conventional group underwent the standard steps of traditional tracheostomy. The operation time, incision length, amount of bleeding, and incidence of postoperative complications were compared between the two groups.Results:The operation time in the rapid group was significantly shorter than that in the conventional group [(4.5 ± 0.9) minutes vs. (19.3 ± 4.7) minutes, t = 23.86, P < 0.001]. The length of incision in the rapid group was significantly shorter than that in the conventional group [(2.8 ± 0.3) cm vs. (4.2 ± 1.3) cm, t = 8.68, P < 0.001]. The amount of bleeding during the surgery in the rapid group was significantly less than that in the conventional group [(4.4 ± 1.6) mL vs. (11.8 ± 4.1) mL, t = 12.99, P < 0.001]. The incidence of postoperative complications in the rapid group was significantly lower than that in the conventional group ( χ2 = 4.66, P = 0.031). Conclusion:The self-developed rapid tracheotomy apparatus for acute tracheotomy can be used to establish an artificial airway quickly and minimally invasively by simplifying the operational steps. It is remarkably innovative to increase safety with open-view operations and decrease the incidence of complications. It can be repeatedly sterilized and reused, which is worthy of clinical application and popularization.

ABSTRACT
Objective To establish the acquired tamoxifen (TAM)-resistant human breast cancer cell line T47D-TamR,compare the 18F-FDG uptake rate between T47D-TamR and its parental cell line T47D,and study the mechanism.Methods Long-term step-wise drug stimulation was used for cell line T47D-TamR establishment and then the cell proliferation and resistance index (RI) were determined by MTT assay.The 18F-FDG uptake rates of T47D-TamR and T47D cells were measured in the setting of different cell counts,reaction time,18F-FDG dosages and glucose concentrations.The LDH activity,cellular ATP level and lactic acid concentration in cell supernatant of T47D-TamR and T47D cells were detected.Western blot was used to examine the expression of ERα,Glut-1,phosphorylated AMPK (p-AMPK) and phosphorylated mTOR (p-mTOR).Two-sample t test and two-way analysis of variance were used to analyze the data.Results T47D-TamR cell line was successfully established and its drug RI was 1.97±0.08,with a significantly decreased cell proliferation efficacy (F =230.10,P＜ 0.05).Significant differences of 18 FFDG uptake rates were found between T47D-TamR cell and T47D cell when changing the cell count,reaction time,and 18F-FDG dosage (F values:419.00-1 116.00,all P＜0.05).The LDH activities of T47D cell and T47D-TamR cell were (0.42±0.04) and (0.32±0.02) U/mg protein,cellular ATP levels were (19.99±0.32) and (14.01±0.70) nmol/mg protein,lactic acid concentrations in cell supematant were (2.95±0.05) and (2.02±0.07) mmol/L,respectively.The differences of above parameters between the two groups were significant (t values:4.39-18.80,all P＜0.05).The relative expressions of ERα,p-AMPK,pmTOR,Glut-1 were 0.26±0.03,0.36±0.06,0.75±0.11,0.35±0.07 in T47D cell,and 0.17±0.02,0.61±0.09,0.52±0.08,0.21±0.04 in T47D-TamR cell,and there were significant differences (t values:12.20-16.45,all P＜0.05) between the two groups.Conclusions Compared with parental cells,T47D-TamR cells have lower 18F-FDG uptake rate,LDH activity,cellular ATP level and lactic acid concentration,increased p-AMPK expression and decreased ERα,p-mTOR,Glut-1 expression,indicating the decreased glycolysis ability in TAM-resistant breast cancer cells.
ABSTRACT
Objective To compare the long term effectiveness of tonsillotomy(TT)vs. tonsillectomy (TE)by hypercator in treatment of obstructive sleep apnea hypopnea syndrome(OSAHS)in children. Methods 119 children with tonsil hypertrophy were diagnosed with OSAHS and included in the study. Among them,57 children underwent TT by hypercator and 62 TE only after preoperative laboratory polysomnography(PSG). All participants were interviewed 5 years after operation to assess the satisfaction of their caregivers,investigate the frequency of respiratory infections,the rate of tonsil regrowth and evaluate their quality of life by Obstructive Sleep Apnea-18(OSA-18). Results Some of them received postoperative PSG. All parents reported alleviation of breathing obstruction,but the postoperative satisfaction in TT group was higher than TE group mainly because of the shorter time return to normal diet. The rate of the respiratory tract infections was not increased in all cases after surgery. Four cases of children were observed with tonsillar regrowth,but no surgery was needed for further treatment. The rate of the dry throat symptoms in TT group was lower than TE group. Conclusions Tonsillotomy by hypercator can effectively eliminate the obstruction symptoms in children with OSAHS,superior to TE for its shorter recovery period and smaller oral mucosal injury and lower rate of tonsils regrowth and it is worth to clinical promotion.

ABSTRACT
Objective To evaluate the feasibility of getting retroperitoneal lymph node biopsy via technique of natural orifice transluminal endoscopic surgery(NOTES)in human being with current available devices.Methods We performed trans-gastric endoscopic biopsy of retroperitoneal lymph node with the aid of laparoscopy in a 50-year-old man,who presented with abdominal pain and enlarged retroperitoneal lymph nodes and signed a written informed consent before the procedure.After routine anesthesia and abdominal skin sterilization,a pneumoperitoneum was induced with a Veress needle placed in the umbilical area,followed by the introduction of a 5-mm trocar.Gastral cavity Was sterilized with antibiotics and povidone iodine.Under laparoscopie optical control,we made a styliform incision in the anterior wall of gastric corpus with a needle knife,and enlarged the incision by a dilatation balloon and then entered the peritoneal cavity with a sterile endoscope.We got two biopsies from the enlarged lymph node with a heat forceps assisted by laparoscopy.The specimen was taken out by retrieval basket through the stomach.The gastric incision Was closed with metal clips.Results The biopsy by means of NOTES was successfully performed without intra-or postoperative complications.The diagnosis was confirmed as lymphoma pathologically.The patient received chemotherapy and was discharged on the sixth postoperative day.There was no short or long-term complication.Conclusion Transgastric access for laparoscopy-assisted biopsy of retroperitoneal lymph node is feasible and safe in human being.
ABSTRACT
OBJECTIVE@#To explore the method and effect of the midfacial degloving approach and modified hemifacial degloving approach associated with nasal endoscopic surgery in the treatment of the nasal diseases.@*METHOD@#Thirty patients with nasal diseases were treated with nasal endoscopic surgery by midfacial degloving approach and modified hemifacial degloving approach. Four cases underwent midfacial degloving approach with standard method, three cases were underwent by hemifacial degloving approach and our modified hemifacial degloving approach associated with nasal endoscopic surgery were performed in twenty-three cases. We used Caldwell-Luc's approaches which located mainly in affected-side, and modified bilateral intercartilaginous incision, which at first peeled off integrality healthy-side cutis and mucosa of nasal septum as well as periosteum of basis nasi. With preserving the integrality of the healthy-side nasal cavity parenchyma, the pyriform aperture incisions extending to the healthy-side vestibule wasn't been cut. With the incisions of septal cartilage of nasal and disease- side cutis and mucosa of nasal septum as well as the pyriform aperture incisions extending to the affected-side vestibule, the lesion were cleared away completely by modified midfacial degloving approach associated with nasal endoscopic surgery.@*RESULT@#All cases cuts achieved primary healing. One of four cases with midfacial degloving approach suffered from straightness of nasal vestibule. One of three cases with hemifacial degloving approach was led to perforation of nasal septum. In 23 cases operated hy modified hemifacial degloving approach, no straightness of nasal vestibule and no perforation of nasal septum was happened.@*CONCLUSION@#The midfacial degloving approach and modified hemifacial degloving associated with endoscopic surgery can achieve the advantages of a widely exposed field for operation, no facial scar, making tumour resection easier, and also no nasal- stuffed in healthy nasal cavity as well as no straightness of nasal vestibule after modified approach.
