Objective: To establish a method for the quality standard of Biyankang granule. Methods: Scutellaria baicalensis Georgi and Puerariae Iobatae radix were identified by TLC. The content of baicalin was determined by HPLC with a Dubhe C18 column (250 mm × 4. 6 mm, 5 mm). The mobile phase was methanol and 0. 4% phosphoric acid with gradient elution. The flow rate was 1. 0 ml· min-1 and the detection wavelength was 280 nm. The column temperature was 30℃ and the injection volume was 10 ml. Re-sults:The spots in TLC were clear without any interference. A good linear relationship was shown within the range of 15. 02-300. 43 m g·ml-1 for baicalin (r=1.000 0). The average recovery of baicalin was 102.62% (RSD =0.72%, n =6). Conclusion: The method is specific with high accuracy and good reproducibility, which can be used for the quality control of Biyankang granule.

Objective The purpose of this study was to compare the image quality of readout-segmented EPI (RS-EPI) and that of standard single-shot echo-planar imaging (SS-EPI) in patients with scrotal diseases. Methods Initial diagnosis of scrotal diseases were included in the prospective study, all patients underwent scrotum routine MRI and RS-EPI, SS-EPI sequence at 3.0 T. A total of 38 patients were recruited qualitative assessment ,and 29 patients proved by operation and pathology (malignant 21 cases and benign 8 cases) were included quantitative analysis.For qualitative comparison of image quality, two readers independently assessed the two sets of DWI, which consisted of identification of structure and geometric distortion of scrotum (epididymis,testes, lesion) using a 5-point Likert scale. For assessment of image parameters, signal-to-noise ratio (SNR), contrast, contrast-to-noise ratio (CNR),apparent diffusion coefficient value of normal testis and testis distortion ratio of anatomical(T2WI)/DWI fusion image were calculated. Inter-observer agreement was assessed with the Kappa statistics, the differences of scores of
RS-EPI and SS-EPI were compared by using Wilcoxon rank-sum test, and image parameters were compared by using paired sample t test. Results There was good reader agreement in the scores, the Kappa value were 0.77, 0.74, 0.80, 0.87. The difference of identification of structure and geometric distortion on RS-EPI and SS-EPI had statistic significance, the RS-EPI was superior to SS-EPI in image quality (all P<0.05).The SNR, contrast of benign lesion for two sequences had no statistic significance(P values were 0.352, 0.124, respectively), but the difference of CNR had statistic significance(P<0.05). The SNR,contrast and CNR of malignant lesion for two sequences had statistic significance (all P<0.05). The mean size of the testis was (35.61 ± 9.78)mm, the mean distance in fusion image of RS-EPI or SS-EPI with T2WI were (3.80 ± 1.32)mm and (7.54 ± 2.62)mm, and the mean distortion ratios of the two set were (11.1 ± 0.6)% and (22.4 ± 19.2)%, respectively, the difference of two sets had statistic significance(P<0.05). There was no significant difference in the ADC obtained by using either DWI method(t=0.396,P=0.796), the mean ADC values of normal testes for RS-EPI and SS-EPI, respectively, were (1.18 ± 0.06) × 10-3mm2/s, (1.24 ± 0.11) × 10-3mm2/s.Conclusion RS-EPI DWI images is a feasible technique in the scrotum for producing high-resolution DWI with reduced geometric distortion and offers potentially superior image quality compared to SS-EPI at 3.0 T.

Objective:To investigate the clinical significance of cytokine levels and routine cytology in bronchoalveolar lavage fluid (BALF) in children with severe Mycoplasma pneumoniae pneumonia (SMPP).Methods:A total of 207 children with Mycoplasma pneumoniae pneumonia who underwent parallel bronchoalveolar lavage in the Department of Respiratory, Shanghai Children′s Hospital, Shanghai Jiaotong University from July 2018 to February 2019 were enrolled in this study.There were 121 patients in the SMPP group and 86 patients in the non-SMPP group.Flow cytometry was used to determine the level of cytokines in BALF.Meanwhile, the cells in BALF were stained and cytokines levels and routine cytology were compared between the 2 groups.Receive operating characteristic(ROC) curves were used to analyze the predictive value of cytokine levels and routine cytology for SMPP.Results:The levels of interleukin(IL)-8, IL-1βand IL-6 and white blood cell count in BALF of SMPP group were significantly higher than those of non-SMPP group [1 717.77 (784.31, 3 304.03) ng/L vs.1 013.03 (469.27, 2 040.52) ng/L, 373.18 (70.08, 941.56) ng/L vs.107.50 (0.10, 489.88) ng/L, 200.74 (41.09, 570.61) ng/L vs.95.47 (0.10, 337.68) ng/L, 1 890.00 (955.00, 3 600.00)×10 6/L vs.1 430.00 (467.50, 2 724.00)×10 6/L]( Z=3.27, 3.45, 2.47, 2.57, all P<0.05). The percentage of macrophages in the non-SMPP group was significantly higher than that in the SMPP group [0.04 (0, 0.12) vs. 0 (0, 0.06)] ( Z=-2.67, P=0.01). The optimal critical value and the area under curve (AUC) of IL-8 were 722.69 ng/L and 0.63 (95% CI: 0.56-0.71, P<0.01), respectively. The optimal critical value and AUC of IL-1β were 166.33 ng/L and 0.64, respectively (95% CI: 0.56-0.72, P<0.01). The optimal critical value and AUC of IL-6 were 142.95 ng/L and 0.60, respectively (95% CI: 0.52-0.68, P<0.05). The optimal critical value and AUC of the total white blood cells were 970×10 6/L and 0.61, respectively (95% CI: 0.53-0.69, P<0.05). The optimal critical value and AUC of the percentage of macrophages were 0.19 and 0.60, respectively (95% CI: 0.32-0.48, P<0.05). Conclusions:Children with SMPP have higher levels of cytokines IL-8, IL-1β and IL-6, a higher white blood cell count, and a lower percentage of macrophages in BALF than children with no SMPP. However, cytokine levels and cytology are inadequate to predict SMPP since they are not effective in the clinical diagnosis of SMPP.

Objective:To examine the clinical effectiveness of modified vaginal hysterectomy for the treatment elderly women with uterine prolapse.Methods:Eighty-two elderly patients with uterine prolapse treated in the Affiliated Hospital of Jiangnan University from January 2017 to August 2020 were selected as research subjects, who were randomly and double-blindly divided into the control group and the observation group, with 41 patients in each group.The control group was treated with traditional vaginal hysterectomy, while the observation group was treated with modified vaginal hysterectomy.Surgical parameters(operating time, intraoperative blood loss and length of hospital stay), total clinical effectiveness rates and the incidences of complications in the two groups were compared.Results:The total effectiveness rate of the observation group was higher than that of the control group(97.6% vs.78.0%, χ2=7.291; P<0.05). The operation time[(71.3±15.5)min vs.(122.7±22.2)min, t=7.379, P=0.008], intraoperative blood loss[(122.5±15.3)ml vs.(297.7±20.7)ml, t=9.820, P=0.000]and hospitalization time[(7.2±1.5)d vs.(10.0±2.9)d, t=7.164, P=0.014]of the observation group were lower than those of the control group.The incidence of complications in the observation group was lower than that in the control group(0.0% vs.14.6%, χ2=7.159, P<0.05). Conclusions:Modified vaginal hysterectomy for elderly patients with uterine prolapse can help improve the clinical effectiveness and reduce the operating time, postoperative length of hospital stay and the incidence of postoperative complications.

Objective To investigate the prognostic influence factors of Solitaire stent thrombectomy in patients with acute anterior circulation macrovascular occlusion. Methods From March 2015 to March 2017,222 consecutive patients with acute anterior circulation macrovascular occlusion admitted to the Department of Neurosurgery,the 101stHospital of People′s Liberation Army and the Nanjing Jinling Hospital were enrolled retrospectively.They were all confirmed by DSA and were treated with Solitaire stent thrombectomy. According to the modified Rankin Scale(mRS) scores at 90 d after treatment,they were divided into a good prognosis group (0-2,n=120) and a poor prognosis group (3-6,n =102). The baseline data and clinical data of the two groups of patients were analyzed,including the risk factors for cardiocerebrovascular diseases,baseline National Institutes of Health Stroke Scale (NIHSS) score,occlusion sites (internal carotid artery or middle cerebral artery occlusion),collateral compensatory,onset to puncture time, operation time,onset to recanalization median time,recanalization status,preoperative Alberta stroke programme early CT score(ASPECTS),and symptomatic cerebral hemorrhage,and then further multivariate logistic regression analysis was conducted for the prognostic factors of patients. Results (1) The rate of good prognosis was 54.1% (120/222).There were no significant differences in patients′ age,NIHSS at admission,ASPECTS at admission,sex,hypertension,occlusion site,and rate of good collateral branches in both groups(all P<0.05).There were no significant differences in other baseline data (all P >0. 05). (2) Onset to puncture time and onset to successful recanalization median time of the patients in good prognosis group was lower than that of the poor prognosis group (182 [138,230]min vs.236[170,305]min, 237[175,269]min vs.288[223,367]min).The proportion of successful recanalization was higher than that of the poor prognosis group (98.3% [118/120] vs.78.4% [80/102]).The proportion of postoperative symptomatic intracerebral hemorrhage was lower than that of the poor prognosis group (2.5% [3/120] vs.21.6% [22/102]).There was significant difference between the two groups (all P <0.01). There was no significant difference in operative time between the two groups (P >0.05). (3)In the single factor analysis,the parameter of P <0.05 was used as an independent variable,and prognosis was used as a dependent variable,multivariate logistic regression analysis showed that the increased age (OR,1.096,95% CI 1.050-1.144),history of hypertension (OR,8.401,95% CI 2.960-23.845),increased baseline NIHSS score (OR,1.071,95% CI 1.007-1.138),prolonged onset to successful recanalization time (OR,1.019,95% CI 1.003-1.035),symptomatic intracerebral hemorrhage after procedure (OR,18.110,95% CI 4.656-70.434) were all the risk factors for poor prognosis(all P<0.05);higher ASPECTS score at admission(OR,0.641,95% CI 0.451-0.911) and successful recanalization (OR,0.127,95% CI 0.024-0.664) were all the protective factors of good prognosis (all P<0.05). Conclusions Higher ASPECTS at admission and successful recanalization were the protective factors of poor prognosis of Solitaire stent thrombectomy in patients with acute anterior circulation macrovascular occlusion.Increased age,history of hypertension,increased baseline NIHSS score,prolonged onset to successful recanalization time,and symptomatic intracerebral hemorrhage after procedure were the risk factors for poor prognosis of Solitaire stent thrombectomy in patients with acute anterior circulation macrovascular occlusion.

Objective To systematically evaluate the adult intraoperatively acquired pressure injury risk prediction model.Methods Related study on IAPI risk prediction model in Chinese and English databases such as CBM,CNKI,PubMed and Web of Science were searched.The language is limited to Chinese and English,and the search time is until November 4,2022.Two researchers independently screened the literature and extracted the data,and applied the bias risk assessment tool of prediction model research to analyze the bias risk and applicability of the included literature.Results 13 articles were included,including 17 models(operation time,age,diabetes,BMI and serum albumin are the most commonly used predictors).Among the 17 models,the area under the curve of 14 models was 0.616 to 0.984,and the other study did not report the AUC results.Among the 13 studies,10 had good applicability,while the remaining 3 had unclear applicability.13 studies have a high risk of bias,mainly because the included studies are retrospective studies,the predictive factors are screened based on univariate analysis,and the predictive outcomes are not defined by guidelines or standardization.Conclusions The existing IAPI risk prediction model for adults has good applicability,but the risk of bias is high,and the construction is not perfect.It is necessary to pay attention to the effectiveness of different risk assessment methods in the later construction,so as to get a better and more accurate risk prediction model and provide some reference and basis for formulating relevant prevention strategies.

Objective:To compare the application effect of remote intelligent rehabilitation system and conventional rehabilitation in rehabilitation of patients with rotator cuff injury following minimally invasive arthroscopic surgery.Methods:A retrospective cohort study was used to analyze the clinical data of 47 patients with rotator cuff injury admitted to Xinhua Hospital, Shanghai Jiao Tong University School of Medicine from January to July 2022, including 18 males and 29 females; aged 45-65 years [(56.7±6.3)years]. All patients underwent minimally invasive arthroscopic surgical repair of rotator cuff rupture. After surgery, 25 patients underwent self-rehabilitation with conventional education (conventional rehabilitation group), and 22 patients underwent systematic rehabilitation with remote intelligent rehabilitation system (remote rehabilitation group). Constant shoulder score, University of California at Los Angeles (UCLA) shoulder score, self-rating anxiety scale (SAS) score, self-rating depression scale (SDS) score and visual analog score (VAS) were compared between the two groups on the day of admission, 4, 8, 12 weeks after surgery and at the last follow-up. Shoulder MRI was applied at 6 weeks after surgery to compare the degree of intra-articular effusion and bone marrow edema between the two groups. The shoulder range of motion of the two groups was compared at 12 weeks after operation. The satisfaction with the rehabilitation of the two groups was compared at the last follow-up.Results:All the patients were followed up for 6-10 months [(8.5±2.2)months]. There was no significant difference in Constant shoulder score, UCLA shoulder score, SAS score, SDS score and VAS between the two groups on the day of admission (all P>0.05). There was no significant difference in Constant score, UCLA score and SAS score between the two groups at 4 weeks after surgery (all P>0.05). The values of SDS score and VAS at 4 weeks after surgery were (31.8±6.6)points and (3.6±1.1)points in the remote rehabilitation group, which were better than those in the conventional rehabilitation group [(40.5±5.6)points and (4.7±1.3)points] (all P<0.05). The values of Constant score, UCLA score, SAS score, SDS score and VAS at 8 weeks after surgery were (62.5±5.5)points, (18.5±3.3)points, (20.5±4.7)points, (22.5±4.6)points and (2.5±0.6)points in the remote rehabilitation group, which were better than those in the conventional rehabilitation group [(41.3±4.7)points, (15.3±3.1)points, (28.5±4.8)points, (38.5±3.7)points and (3.3±1.3)points] ( P<0.05 or 0.01). The values of Constant score, UCLA score, SAS score and SDS score at 12 weeks after surgery were (85.4±6.4)points, (32.2±3.8)points, (13.6±2.8)points and (18.4±3.9)points in the remote rehabilitation group, which were better than those in the conventional rehabilitation group [(60.3±6.7)points, (25.2±4.1)points, (21.5±4.9)points and (26.7±6.6)points] (all P<0.05), while there was no significant difference in VAS between the two groups ( P>0.05). At the last follow-up, there were no significant differences in Constant score, UCLA score, SAS score, SDS score and VAS between the two groups (all P>0.05). MRI of the shoulder joint at 6 weeks after surgery indicated that the degree of intra-articular effusion in the shoulder joint and bone marrow edema of the proximal humerus in the remote rehabilitation group was significantly reduced than that in the conventional rehabilitation group. At 12 weeks after surgery, the remote rehabilitation group had better shoulder range of motion than the conventional rehabilitation group ( P<0.05 or 0.01). At the last follow-up, the satisfaction with the rehabilitation of the remote rehabilitation group was better than that of the conventional rehabilitation group ( P<0.01). Conclusion:For patients with rotator cuff injury who undergo minimally invasive arthroscopic surgery, postoperative application of remote intelligent rehabilitation system, in comparison with the conventional rehabilitation system, can help to facilitate shoulder function recovery, anxiety and depression improvement and pain relief in the early stage, reduce shoulder soft tissue and bone marrow edema of the shoulder, and increase shoulder range of motion and patients′ satisfaction with the rehabilitation.
