OBJECTIVETo observe the clinical effect difference between special penetration needling and conventional penetration needling for the refractory peripheral facial paralysis.

METHODSA total of 97 patients with intractable facial paralysis were randomized into an observation group (49 cases and 2 dropping) and a control group (48 cases and 4 dropping). In the observation group, special penetration needling at an angle about 45° between the penetration needle and paralysis muscle bundle was used, Yangbai (GB 14) through Touwei (ST 8), Yangbai (GB 14) through Shangxing (GV 23), Sizhukong (TE 23) through Yuyao (EX-HN 4), Qianzhen (Extra) through Yingxiang (LI 20), mutual penetration between Yingxiang (LI 20) and Jiache (ST 6). Conventional penetration needling was applied in the control group, Yangbai (GB 14) through Yuyao (EX-HN 4), Cuanzhu (BL 2) through Yuyao (EX-HN 4), mutual penetration between Dicang (ST 4) and Jiache (ST 6), Qianzheng (Extra) through Dicang (ST 4), Sibai (ST 2) through Yingxiang (LI 20). Three groups of electroacupuncture (discontinuous wave, 1 Hz) with tolerance were connected respectively in the two groups, Yangbai (GB 14) and Sizhukong (TE 23), Yangbai (GB 14) and Qianzheng (Extra), Yingxiang (LI 20) and Jiache (ST 6) in the observation group, Yangbai (GB 14) and Cuanzhu (BL 2), Dicang (ST 4) and Jiache (ST 6), Qianzheng (Extra) and Sibai (ST 2) in the control group. TDP was applied in the two groups at the affected Yifeng (TE 17), Jiache (ST 6) and Qianzheng (Extra), which were around the ear. Perpendicular insertion was used at Yifeng (TE 17) at the affected side and Hegu (LI 4) at the healthy side and bilateral Zusanli (ST 36). The needles were retained for 30 min. The treatment was given for 3 courses, once a day and 10 days as a course, 5 days at the interval. House-Brackmann (H-B) facial nerve grading score was recorded before and after treatment. The clinical effects were compared.

RESULTSThe H-B scores after treatment in the two groups were higher than those before treatment (both <0.05), with better result in the observation group (<0.05). The cured and markedly effective rate of the observation group was 74.5% (35/47), which was better than 47.7% (21/44) of the control group (<0.01).

CONCLUSIONSpecial penetration needling at an angle about 45° between the penetration needle and paralysis muscle bundle is better than conventional penetration needling for refractory facial paralysis.

Objective To investigate the value of renal CT volumetric texture analysis with machine learning radiomics in assessment of pathological grade of clear cell renal cell carcinoma(ccRCC). Methods Thirty-four biopsy-confirmed ccRCC subjects who had four-phase CT scanning (NC:non-contrast, CM: Corticomedullary, N: Nephrographic, E: Excretory) were collected retrospectively from June 2013 to October 2017 for the study.Non-rigid registration was performed on multi-phase CT images in reference to CM-phase.Each lesion was segmented on CM-phase CT images using our in-house volumetric image analysis platform,"3DQI".A set of fifty-nine volumetric textures,including histogram,gradient,gray level co-occurrence matrix(GLCM),run-length(RL),moments,and shape,was calculated for each segment lesion in each phase as parameters for the training/testing of Random Forest (RF) classifier. Four groups according to pathological Fuhrman grade on a scaleⅠtoⅣ,these tumors were then divided into low(Ⅰ+Ⅱ) and high grade ( Ⅲ + Ⅳ) groups. Feature selection was performed by Boruta algorithm. A 10-fold cross-validation method was applied to validate the RF performance by receiver operating characteristic (ROC) curves analysis to determine the diagnostic accuracy of the model. Results Subjects were divided into four groups by Fuhrman grade on a scaleⅠtoⅣ:3 cases gradeⅠ,19 cases gradeⅡ,8 cases gradeⅢand 4 cases gradeⅣ.In CM-phase,kurtosis and long-run-emphasis(RLE)were selected the most important textures for ccRCC staging among 59 features. The area under curve (AUC) of ROC was 0.88 (79% sensitivity and 82% specificity)by using kurtosis and RLE textures.The mean values of kurtosis and RLE were(-20.00±22.00)×10-2and(3.00±0.40)×10-2for low group,whereas(31.00±32.00)×10-2and(5.00± 0.02)×10-2for high group.Within the mean±SD range of statistics,radiomics can distinguish between low and high grade tumors.In multi-phase analysis,three most important features were selected among 236(59× 4) textures: kurtosis (CM-phase), GLCM homogeneity I (HOMO 1) (E-phase), and GLCM homogeneity 2 (HOMO2)(E-phase).The mean values of HOMO 1(E-phase)and HOMO 2(E-phase)were(19.00±0.03)× 10-2and(11.00±0.02)×10-2for low group,whereas(22.00±0.03)×10-2and(14.00±0.02)×10-2for high group. The AUC was 0.92(93% sensitivity and 87% specificity)by using these three textures. Conclusion This study has demonstrated that renal CT volumetric texture analysis with machine learning radiomics could preoperative accurately perform cancer staging for ccRCC.

Objective:To evaluate the safety of naborphine hydrochloride combined with propofol in painless colonoscopy diagnosis and treatment of hypertensive patients.Methods:From October 2018 to September 2020, 900 patients with ASA grade Ⅰ to Ⅲ, aged 18 to 65, who underwent colonoscopy in Zhuhai Hospital Affiliated to Jinan University and Shanghai East Hospital Affiliated to Tongji University were prospectively selected. According to the random number table method, the patients were divided into 3 groups ( n=300): naborphine hydrochloride group 1 (N1 group, intravenous injection of 0.05 mg/kg naborphine hydrochloride); naborphine hydrochloride group 2 (N2 group, intravenous injection of 0.1 mg/kg naborphine hydrochloride); sufentanil group (SF group, intravenous injection of 0.1 μg/kg sufentanil). During anesthesia induction, propofol was combined with sedation, and the dose of propofol was 1.5 mg/kg. The systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), pulse oxygen saturation (SpO 2), respiratory rate (RR), and mean arterial pressure (MAP) of the three groups were compared before anesthesia (T 0), during induction (T 1), 1 min after induction (T 2), 2 min after induction (T 3), 3 min after induction (T 4) and 4 min after induction (T 5), and the bispectral index (BIS) were monitored. At the same time, the examination time, total dosage of propofol, recovery time, postoperative Visual Analogue Scale (VAS) score and perioperative anesthesia related adverse reactions of the three groups were compared. Results:There was no significant difference among the three groups in examination time, total dosage of propofol, recovery time, postoperative VAS score and adverse anesthetic reactions (all P>0.05). There was no significant difference in HR, SpO 2 and RR among the three groups at different time points (all P>0.05). The SBP, DBP and MAP in N1 group at T 1, T 3, T 4 and T 5 were lower than those in SF group (all P<0.05); The SBP, DBP and MAP in N2 group at T 1, T 3 and T 4 were higher than those in N1 group (all P<0.05). The BIS in T 3 and T 4 of N2 group was higher than that of N1 group (all P<0.05). Conclusions:0.1 mg/kg naborphine hydrochloride combined with propofol for painless enteroscopy in patients with hypertension has fine anesthetic effect and safety.

Objective:To explore the imaging changes of lung lesions in patients with imported COVID-19 when reaching the discharge standard.Methods:The clinical and CT imaging data of 60 cured patients with imported COVID-19 and discharged from January to February 2020 in Anhui Province were retrospectively collected. At the initial diagnosis, 5 cases were mild, 53 were ordinary, and 2 were severe. The clinical characteristics of the patients and the characteristics of chest CT images at discharge were analyzed.Results:Fever (57 cases) and cough (55 cases) were the main symptoms in 60 patients. In 5 mild patients, 3 cases were negative in the whole course of CT examination, 2 cases were negative in the first time and abnormal in the second time. The first CT imaging features of 55 patients (53 common type and 2 severe type) were mainly bilateral lung involvement (51 cases), multiple lesions (33 cases), more common under the pleura (40 cases), and ground glass opacities were the most common (55 cases). The features of chest CT in clinical outcomes were that the ground glass shadow in the lung gradually faded and was completely absorbed (19 cases); the scope of ground glass shadow in the lung expanded and progressed to crazy-paving, consolidation shadow, and the lesion gradually absorbed again followed by fibrous cord shadows (27 cases); ground-glass opacities in the lungs quickly progressed to a consolidation and then slowly absorbed. Most of the lesions were accompanied by more residual fibrous cord shadows (4 cases). In 2 severe patients, the lesions in the lungs were larger ground glass, and a large amount of fibrous foci remained after slow absorption.Conclusions:Chest CT plays an important role in the diagnosis and treatment of imported COVID-19, and the degree of lung involvement seen on CT images is in good agreement with clinical outcome.
