OBJECTIVE To investigate the incidence rate of nasal septum fracture and it's influence on the effect of nasal bone reduction. METHODS Retrospective analysis of 212 cases of nasal fracture compared with nasal septum deviation were carried out. Among these cases 112 treated with nasal bone reduction only was called group A; the other cases were treated with nasal reduction concomitantly with septoplasty. Among them 58 cases were diagnosed with nasal septum fracture, it was called group B; 42 cases were diagnosed with nasal septum deviation, it was called group C. The postoperative nasal deformity rate was assessed, and the intraoperative findings of nasal septum contrast with preoperative CT diagnosis was analysed. RESULTS Three months after the operation, 27 cases (24.1%) of nasal deformity were found in group A; 9(9.0%) cases of nasal deformity were found in group B+C; septum fracture was found in 58 cases (100%) in group B and 30(71.8%) cases in group C introperatively. The diagnosis rate of nasal septum fracture by CT was 58.0%, while it's incidence rate was 88.0%. CONCLUSION More nasal septum fractures were observed introperatively than CT findings, and septoplasty concomitantly with nasal bone reduction can obviously reduce the rate of nasal deformity.

OBJECTIVE:To investigate the effects of NOS1AP rs12742393 A/C gene polymorphism on lipid-regulating re-sponse of rosuvastatin calcium. METHODS:Two hundred and tuirty six patients with coronary heart disease(CHD)were selected from cardiology department of our hospital during Jan. 2014-Jun. 2015,and then given rosuvastatin calcium and other symptomatic treatment for 12 weeks. Polymorphism of NOS1AP rs12742393 A/C was detected by PCR-RFLP. The levels of TG,TC,HDL-C and LDL-C were detected by photoelectric colorimetry before treatment and 4,12 weeks after treatment. The serum relationship of genotype with the level of blood lipid was analyzed. RESULTS:Among 236 CHD patients,there were 131 cases of AA genotype (55.5%),98 cases of AC genotype(41.5%) and 7 cases of CC genotype(3.0%);genotype and allele frequencies met the Har-dy-Weinberg balance(P>0.05). There were 132 patients with normal blood lipid and 104 patients with hypercholesterolemia;there was statistical significance in genotype and allele frequencies (P<0.05). Among 104 CHD patients with hypercholesterolemia be-fore treatment,there was no statistical significance in the levels of TG,TC,LDL-C and HDL-C between AA genotype and AC+CC genotype(P>0.05). 4th and 12th week after treatment,the levels of TG,TC and LDL-C in different genotypes were all de-creased significantly;4th week after treatment,the level of LDL-C in AC+CC genotype was significantly lower than AA genotype, and the change compared to before treatment was significantly more than AA genotype,with statistical significance (P<0.05). There was no statistical significance in the level of HDL-C among different genotypes compared to before treatment;there was no statistical significance in the levels of TG,TC and HDL-C 4th,12th week after treatment and their changes compared to before treatment between AA genotype and AC+CC genotype;there was no statistical significance in the level of LDL-C 12th week after treatment and their changes between AA genotype and AC+CC genotype(P>0.05). CONCLUSIONS:NOS1AP rs12742393 A/C gene polymorphism is associated with CHD complicated with hypercholesterolemia;the C allele of NOS1AP rs12742393 may strengthen the response of CHD patients with hy-percholesterolemia to rosuvastatin calcium through influencing the level of LDL-C.

Objective:To investigate the effect of short single reverse-α fixation of nasobiliary tube after endoscopic nasobiliary drainage.Methods:From January 2019 to October 2019, the patients who performed with endoscopic nasolbiliary drainage in Tongji University Affiliated Shanghai East Hospital were randomly divided into experimental group (short single reverse-α fixation, 155 cases) and control group (routine reverse-α fixation, 137 cases). The incidences of the fixation time, prolapse rate, nursing time, scores of nasal comfort and bile flow rate of nasobiliary duct were evaluated between the two groups.Results:The average time of nasobiliary duct fixation was (18.31±1.67) s, the prolapse rate was 5.2% (8/155) and the time of nursing was (35.03±2.68) s, which were lower than those of the control group (46.50±5.50) s, 13.9% (19/137) and (72.07±7.63) s. The difference was statistically significant ( t or χ 2 values were 60.795, 6.570, 56.629, P<0.01 or 0.05). The comfort score of the experimental group was (4.61±1.06) points, the bile flow rate was (241.52±53.95) ml/days, which were higher than (5.76±0.76) points and (174.09±47.55) ml/days of the control group, the difference was statistically significant ( t values were 10.448, 11.265, P<0.01). Conclusions:Shortening the length of nasobiliary duct combined with single reaction "α" method has the advantages of simper operation and nursing, low prolapse rate, high comfort and good drainage effect. It is worthy of clinical application.

Objective To investigate the expression of glucagon-like peptide-1 receptor (GLP-1R) of skeletal muscle cells and the changes of skeletal muscle microstructure of diabetic rats, and to explore the relationship between the expressions of GLP-1R and insulin resistance in skeletal muscle. Methods Male Wistar rats were divided into two groups, normal glucose tolerance ( NT, n =25 ) , diabetes group ( DM group, n=30), the methods of creating diabetes model were used high-sugar high-fat diet and low-dose in-traperitoneal injection of streptozotocin. Immunohistochemical methods was used to detect the expression of GLP-1R in the muscle cells. The number of GLP-1R positive cells in the muscle of two groups was observed and compared. The relationship was analyzed between the homeostasis model assessment insulin resistance (HOMA-IR) and the number of GLP-1R positive cells. Results ⑴Compared to the NT group, the num-ber of GLP-1R positive cells in muscle of DM group was decreased (P<0. 05); ⑵ Compared to the NT group, HOMA-IR was increased in DM group (P<0. 05);⑶ Pearson correlation analysis showed that the percentage of GLP-1R positive cells expressed in rat skeletal muscle was negatively correlated with HOMA-IR (r= -0. 538, P<0. 01). Conclusions The expression of GLP-1R positive cells was decreased in the skeletal muscle of diabetic rats, insulin resistance increased. Therefore, the expression of GLP-1R on skele-tal muscle cells may promote the development of insulin resistance and diabetes mellitus.

Effective prevention and control measures should be developed and implemented to the occurrence of adverse factors, so as to reduce the occurrence of depression symptoms.

OBJECTIVE To invest igate the therapeutic effects of music combined cognitive behavioral therapy on subjective tinnitus and the changes in spectral characteristics of resting electroencephalogram(EEG) before and after treatment under eyes closed condition. METHODS 8 patients with subjective tinnitus were enrolled as experimental group including 4 males and 4 females, with a mean age of 33.57±8.52 years from 18 to 40 years, 6.00±3.63 months of illness and right-handedness. Music combined cognitive behavioral therapy included a total of 6 sessions of treatment. The initial session of the treatment aimed to establish basic trust with the patient and understand the patient's personality, tinnitus symptoms, medical history, and other basic conditions. The light music which was specially processed by mactching the frequency and intensity to the patient's tinnitus were selected as combined audio of cognitive behavioral therapy. 7 minutes of closed-eye resting state EEG, THI scale, VAS scale, and SAS scale of the patients with subjective tinnitus were collected. The last 5 sessions was a tailored relaxation therapy including training and counseling patients to understand the treatment feedback after each meeting. After 3 months of the therapy, 7 minutes of EEG, THI, VAS and SAS scales of the 8 patients were asessed. The results of 7min-EEG, THI, VAS, and SAS scales were compared in patients with tinnitus before and after treatment. In addition, 8 patients with normal hearing and without tinnitus were enrolled as control group including 4 males and 4 females, with a mean age of 21.26±7.56 years from 20 to 45 years and right-handedness. The control group underwent 7 minutes of EEG examination. RESULTS The difference between the two groups before treatment was statistically significant(t =4.404, P <0.05). The full-band(0.5-44 Hz) energy of EEG before and after treatment in 8 patients with subjective tinnitus was statistically significant(t =3.705, P <0.05), and the average power of EEG after treatment in the experimental group and the control group was similar. The THI scale(t =3.664, P <0.05) and VAS scale(t =3.265, P <0.05) were compared before and after treatment and the difference was statistically significant. The difference of SAS scales between the two groups was not statistically significant(P >0.05). CONCLUSION Music combined with cognitive behavioral therapy has a significant effect on subjective tinnitusand the closed-eye resting state of brain power can show the recovery of subjective tinnitus of patients objectively which has significance for rehabilitation.

Objective: To establish the Wistar rat model of acute diquat poisoning and observe the pathological damage of main target organs. Methods: Thirty-six Wistar rats were randomly divided into six groups (n=6) , including one normal saline control group and five treatment groups which were separately given single-dose of intragastric administration at the doses of 46.2 mg/kg, 77.0 mg/kg, 115.5 mg/kg, 231.0 mg/kg and 346.5 mg/kg. The pathological changes of lung, liver and kidney were observed by hematoxylin and eosin (HE) and Masson staining. The optimal dose was determined according to the general situation and pathological changes. Thirty-six Wistar rats were randomly divided into five treatment groups and one normal saline control group. Treatment groups were given single-dose of intragastric administration according to the optimal dose. The rats were sacrificed at 1st, 3rd, 7th, 11th and 14th day after exposed, respectively. The activity of serum glutamic-pyruvic transaminase (ALT) and glutamic-oxalacetic transaminase (AST) were measured by chemical colorimetry. The pathological changes of lung, liver and kidney were observed by HE and Masson staining. Results: According to 14 d survival rate, the toxic symptoms and pathological changes, 115.50 mg/kg was determined the best dose. Given single-dose of intragastric administration at the doses of 115.50 mg/kg, it was found that the serum AST and ALT activity of rats on the first and third day of exposure was significant higher than those in control group. The results of pathological examination exhibited that in 115.50 mg/kg group, the pathological changes of lung, liver and kidney began to appear on the first day of exposure, the pathological changes were the most serious on the third day, and then gradually alleviated. On the 14th day, the alveolar septum was slightly widened, with inflammatory cell infiltration, local alveolar cavity became narrow, atrophy, peripheral alveolar compensation, bronchi and alveolar septum collagen fiber proliferation; The local renal tubular epithelial cells were enlarged and necrotic; the central vein surrounding hepatic cells showed vacuolar degeneration with punctate necrosis. Conclusion The rat model of acute diquat poisoning can be successfully induced by single-dose of intragastric administration. The condition of wistar rats and the pathological damage of the main target organs could be observed during the whole course of 115.50 mg/kg administration.
