BACKGROUND: The minimally invasive axial lumbar interbody approach (AxiaLIF) for L4–S1 fusion has been applied in America and Europe, and has obtained satisfactory curative efficacy. Because of significant anatomical differences between Chinese and Europeans and Americans, whether AxiaLIF is appropriate for Chinese remains unclear. Moreover,there are some problems in the application of AxiaLIF, so how to optimize AxiaLIF is a key to its promotion in China.OBJECTIVE: To provide anatomical data for the design of axial screws suitable for Chinese through measuring the mid axial line of the lateral lumbar radiograph and cross sections of L5 and S1 on lumbar CT in normal Chinese population.METHODS: The lateral lumbar radiographs from Chinese healthy population were selected, including 35 males and 30 females, the axial height of S1, the disc distance between L5 and S1, and the axial height of L5 were measured so as to provide anatomical data for designing the length of the axial screw. The transverse and sagittal diameters of L5 and S1 in the lumbar CT of 26 adult healthy males and 24 healthy females were measured to provide anatomical data for designing the diameter of the axial screw.RESULTS AND CONCLUSION: (1) The axial height of S1 in males and females was (26.76±3.94) mm and (22.91±2.91) mm, respectively (P < 0.05). The disc distance between L5 and S1 was (12.62±1.90) mm for males and (11.92±1.78) mm for females (P > 0.05). The axial height of L5 was (29.12±2.18) mm for males and (26.91±2.47) mm for females (P <0.05). (2) The transverse diameter of S1 was (49.14±4.14) mm for males and (46.11±4.44) mm for females (P < 0.05).The transverse diameter of L5 was (41.34±4.31) mm for males and (43.12±3.71) mm for females (P < 0.05). The sagittal diameter of L5 was (34.48±2.32) mm for males and (33.03±3.48) mm for females, and the sagittal diameter of S1 was (35.65±4.28) mm for males and (33.53±3.26) for females, (both P > 0.05). (3) That is to say, this study provides the anatomical data for designing the axial screws suitable for the lumbar fusion of Chinese by measuring the mid axial line of the lateral lumbar radiographs and the cross sections of L5 and S1 on lumbar CT. The image measurement method can be used to analyze the preoperative images of the patients to predict the feasibility of the surgical approach and pre-select the internal fixation model for personalized screw positioning.

Objective:To investigate the significance of CT imaging features in the diagnosis of first-episode paranoid schizophrenia.Methods:Forty-five patients with first-episode paranoid schizophrenia admitted to Shaoxing 7 th People's Hospital from January 2018 to January 2019 were included in the study group. An additional 40 healthy controls who received health examination were included in the control group. All participants underwent head CT scans and CT values of cerebral lobes were measured. CT imaging features of first-episode paranoid schizophrenia were analyzed. The recurrence rate of paranoid schizophrenia was calculated. The diagnostic effect of CT imaging on paranoid schizophrenia was evaluated. Results:The CT value of the frontal lobe in the study group was significantly lower than that in the control group [(33.1 ± 1.4) HU vs. (36.9 ± 2.1) HU, t = 9.914, P < 0.001]. The proportions of patients having ventricular enlargement, sulcus widening, arachnoid cyst and cisterna magna in the study group were 51.1%, 24.4%, 31.1% and 20.0% respectively, which were significantly higher than 5.5%, 2.5%, 2.5% and 2.5% respectively in the control group ( χ2 = 21.688, 8.411, 11.928, 4.675, all P < 0.05). The recurrence rate of paranoid schizophrenia in the study group was 22.2% (10/45). The CT value of the left and right frontal lobe in patients with recurrent paranoid schizophrenia was (32.1 ± 1.7) HU and (32.5 ± 1.6) HU respectively, which was significantly lower than (35.0 ± 1.9) HU and (34.9 ± 1.7) HU in patients without recurrent paranoid schizophrenia ( t = 4.348 and 3.985, both P < 0.001). Conclusion:Patients with first-episode paranoid schizophrenia have brain structural abnormalities, as manifested by ventricular enlargement, sulcus widening, arachnoid cyst, and cisterna magna. CT imaging features are of great value in the diagnosis of first-episode paranoid schizophrenia. It deserves wide popularization and has a great innovation value.

Objective To explore the effect of quality control circle (QCC) on reducing the incidence of complications in the patients with peritoneal dialysis (PD). Methods Eighty-nine patients who underwent peritoneal dialysis after discharge were divided into QCC group (45 cases) and control group (44 cases) according to random sampling method. Both groups were followed up regularly, QCC activity was applied in patients of the QCC group on the basis of the QCC activity procedure. The intervention time was 1 year. The blood pressure, standard rate of urea clearance index, peritonitis incidence, catheter drift rate, infection incidences of external orifice of catheter, admission rate of complications and peritoneal dialysis withdrawal incidence between 2 groups were compared. Results After interference, the systolic and diastolic blood pressure in QCC group were significantly lower than those in control group:(124.11 ± 13.07) mmHg (1 mmHg=0.133 kPa) vs. (132.68 ± 12.09) mmHg and (72.13 ± 10.51) mmHg vs. (78.91 ± 11.79) mmHg, and there were statistical differences (P<0.05). The standard rate of urea clearance index in QCC group was significantly higher than that in control group:95.56%(43/45) vs. 81.82%(36/44), and there was statistical difference (P<0.05). After interference, the peritonitis incidence and admission rate of complications in QCC group was significantly lower than those in control group: 2.22% (1/45) vs. 13.64% (6/44) and 0 vs. 9.09% (4/44), and there were statistical differences (P<0.05). There were no statistical differences in catheter drift rate, infection incidences of external orifice of catheter and peritoneal dialysis withdrawal incidence between 2 group (P>0.05). The Spearman correlation analysis result showed that peritonitis was negatively correlated with education level (r = -0.28, P < 0.05), and standard rate of urea clearance index was positively correlated with education level (r = 0.21, P < 0.05). Conclusions The QCC management model can reduce the incidence of complications in patients with peritoneal dialysis.

Objective To explore the expression of aquaporin (AQP)-4 in white matter of spinal cord after spinal cord contusion (SCC). Methods 88 adult Sprague-Dawley rats were assigned randomly to sham operation group and SCC group. The model was established by Al-len's method. BBB sore was used to assess the motor function of rats. The relative expression of AQP-4 mRNA was determined by Q-PCR technique. The localization of AQP-4 was observed by immunohistochemistry. Results BBB score showed motor dysfunction in SCC group, and it increased 7 and 14 days after SCC (t>5.061, P<0.001). The level of AQP-4 mRNA decreased on the 1st and 3rd days (t>50.44, P<0.001), and increased on the 5th day (t=-3.968, P=0.001), and lasted until the 28th day (t=-4.227, P=0.001) compared with that on the 3rd day. The immunohistochemistry showed AQP-4 was located on the process of glial cell and vascular endothelial cells in white matter of spi-nal cord. Conclusion AQP-4 may play various roles at different stages in SCC.

Objective To study the effect of dexmedetomidine and midazolam on hemodynamics and sedation in patients with nasal intubation.Methods Forty patients whose ASA grade Ⅰ-Ⅱ and anticipated difficult airway were randomly divided into dexmedetomidine group(group D,20 cases)and midazolam group(group M,20 cases)according to the admission number.In group D,dexmedetomidine 1 μ g/kg were constant speed pumped in 10 minutes.In group M,midazolam 0.03 mg/kg were intravenous injected.Then nasal intubation were carried.Systolic blood pressure(SBP),diastolic blood pressure(DBP),mean arterial blood pressure(MAP),heart rate(HR),pulse oxygen saturation(SpO2),Ramsay sedation score,rate-pressure product(RPP),tip perfusion index(TPI)were recorded and compared before anesthesia (T0),fiberoptic bronchoscope pass by later nostril(T1),to spy on epiglottis(T2),intubation succeed(T3),after intubation 1 minute(T4)and after intubation 3 minutes(T5).Airway score and postoperative visit were evaluated.Results SBP,DBP,MAP,HR,RPP in group M were significantly higher at T1-T3 than those at T0 (P＜0.05),and were significantly higher than those in group D at the same time(P＜ 0.05).There was no significant difference in group D(P ＞ 0.05).Ramsay sedation score and TPI at T1-T3 in group M were significantly lower than those at To(P ＜0.05).Ramsay sedation score and TPI at T1-T5 in group D were significantly higher than those at T0(P ＜ 0.05),and were significantly higher than those in group M at the same time(P ＜ 0.05).The rate of airway score 1 score and intubation satisfaction in group D were significantly higher than those in group M[100％(20/20)vs.30％(6/20),90％(18/20)vs.50％(10/20)](P＜ 0.05).The rate of throat ache in group D was significantly lower than that in group M[5％(1/20)vs.35％(7/20)](P ＜0.05).Conclusions For difficult airway patients with nasal intubation during dexmedetomidine infusion,hemodynamics is stable and sedation is satisfied.

AIM:To investigate the value of pattern visual evoked potential (PVEP) and flash electroretinogram (FERG) in early diagnosis and prevention of diabetic retinopathy (DR), analyzing the correlation of early stage DR with PVEP and FERG.
METHODS: Sixty patients, 30 males and 30 females, participated in observation group. Their average age was 19. 42 ± 7. 78years. The duration of DM was < 5a. Best corrected visual acuity was 5. 0. Fasting blood glucose was 7. 8± 3. 6mmol/ L. There were 60 subjects, 30 males and 30 females, in control group. Their average age was 17. 2 ± 6. 52years. Best corrected visual acuity was 5. 0. Every participator was tested with PVEP and FERG according to ISCVE standard. The amplitude of PVEP and P100 latency were recorded. And the b-wave latency, b-wave amplitude, a - wave latency, a - wave amplitude were showed down.
RESULTS: In observation group, P100 amplitude decreased and P100 latency increased, compared to those of control group ( P< 0. 01); b - wave latency, b -wave amplitude, a - wave latency, a - wave amplitude were different from those in control group(P<0. 01); the fasting blood glucose kept stable; P100 amplitude, b -wave amplitude and a-wave amplitude were not related to the DM duration; P100 latency, a-wave latency and b-wave latency were related to the DM duration.
CONCLUSION: PVEP are sensitive to optic neuron damage; FERG is desirable to detect the lesion of Müller cells and bipolar cells. P100 amplitude by PVEP, b-wave amplitude by FERG may be the most sensitive parameter for DR at early stage.
