OBJECTIVE To establish the fingerprint of Shenfukang Ⅱ capsule(SC-Ⅱ), and to screen out its indicative compounds for quality control combined with chemometrics methods and network pharmacology. METHODS The HPLC fingerprint of 10 batches of SC-Ⅱ was established, and similarity evaluation was analyzed by Similarity Evaluation System for Chromatographic Fingerprint of TCM(2012 A Edition) to determine common peaks; common peaks were identified through standard comparison. Chemometrics methods was used to evaluate quality of 10 batches of SC-Ⅱ, and network pharmacology was used to screen out core targets and pathways of SC-Ⅱ. Combined with the above results, indicative compounds for quality control of SC-Ⅱ were screened out. RESULTS A total of 37 common peaks were obtained in the HPLC fingerprint, the similarity of samples was greater than 0.97. Twenty compounds were identified as morroniside, loganin, paeoniflorin and et al. The samples were divided into two categories by chemical pattern recognition, salvianolic acid B, morroniside, salvianolic acid A and paeoniflorin were differential marker compounds for SC-Ⅱ. Network pharmacology predicted that active compounds such as salvianolic acid B, paeoniflorin and morroniside might exert pharmacological effects through 45 core targets and 15 main pathways. The research preliminary preliminarily predicted that morroniside, paeoniflorin and salvianolic acid B were quality control index components for SC-II. CONCLUSION The established HPLC fingerprint method is simple and good repeatability. The quality control indicative compounds of SC-Ⅱ can provide a basis for its quality control.

Objective To investigate the relationship between gait spatiotemporal parameters and balance function in stroke hemiplegic patients. Methods From September, 2018 to March, 2020, 76 stroke hemiplegic patients (38 in Brunnstrom Ⅳ and V, respectively) were assessed balance function with Active Balancer EAB-100 and Star Excursion Balance Test (SEBT), and gait parameters of speed, cadence and asymmetry, named step length asymmetry ratio (SLA), swing time asymmetry ratio (SWTA), stance time asymmetry ratio (STA), maximum flexion angle ratio (MFA) of hip and knee. The correlation among gait parameters and balance function was analysed. Results The balance and gait parameters were better in those in Brunnstrom V than in Brunnstrom Ⅳ (|t| > 2.268, P < 0.05). The speed and cadence correlated with the most balance indexes (|r| > 0.335, P < 0.05). SLA correlated with SEBT in Brunnstrom Ⅳ patients (r = -0.467~-0.613, P < 0.01), while it correlated with medial-lateral (M-L) stability limits in Brunnstrom V patients (r = -0.356, P = 0.028). SWTA correlated with stability limit of Anterior-Posterior (A-P) (r = -0.335, P = 0.040) and M-L (r = 0.510, P = 0.001), and most of SEBT (r = -0.330~ -0.445, P < 0.05) in Brunnstrom Ⅳ patients. MFA of hip and knee correlated with balance indexes in Brunnstrom Ⅳ patients (|r| > 0.326, P < 0.05), while MFA of knee correlated with most balance indexes in Brunnstrom V patients (r > 0.329, P < 0.05), and MFA of hip correlated with A-P stability limit (r = 0.369, P = 0.023). Conclusion Both speed and cadence of steps can well respond to the balance function in stroke hemiplegic patients. For the asymmetry, it is related with balance in patients with poorer recovery.

Objective    To compare the short- and long-term efficacy of surgery and endoscopy in the treatment of early esophageal cancer by a systematic review and meta-analysis. Methods    We extracted data independently from The Cochrane Library, PubMed, EMbase, Web of Science for studies comparing surgery with endoscopy from 2010 to 2020. The primary outcomes including R0 resection rate, long-term overall survival (OS), disease-specific survival (DSS), major complications, recurrence, hospital stay and cost. Meta-analysis was performed using RevMan 5.3 and Engauge Digitizer was used to extract survival curves from relevant literature, and relevant data were calculated based on statistical methods. Results    A total of 17 studies involving 3 705 patients were included. It was found that patients in the surgery group had a higher R0 resection rate compared with the endoscopic group (OR=0.13, 95%CI 0.07 to 0.27, P<0.001, I2=6%). The total complications rate of resection of esophageal cancer was higher than that of the endoscopic group (OR=0.28, 95%CI 0.16 to 0.50, P<0.001, I2=68%). The length of hospitalization in the endoscopic group was obviously shorter than that in the surgery group (MD=–8.28, 95%CI –12.44 to –4.13, P<0.001, I2=96%). The distant recurrence rate (OR=0.58, 95%CI 0.24 to 1.41, P=0.230, I2=0%) and the local recurrence rate after resection (OR=1.74, 95%CI 0.66 to 4.59, P=0.260, I2=40%) in the endoscopic group was similar to those of the surgery group. There was no significant difference in 5 year-OS rate between the two groups (HR=0.86, 95%CI 0.67 to 1.11, P=0.25, I2=0%), which was subdivided into two groups: adenocarcinoma (HR=0.55, 95%CI 0.15 to 2.05, P=0.37, I2=0%) and squamous cell carcinoma (HR=0.68, 95%CI 0.46 to 1.01, P=0.06, I2=0%), showing that there was no difference between the two subgroups. There was no significant difference in the DSS rate (HR=0.72, 95%CI 0.49 to 1.05, P=0.090, I2=0%) between the two groups. The cost of the surgery group was significantly higher than that of the endoscopic group (MD=–12.97, 95%CI –18.02 to –7.92, P<0.001, I2=93%). Conclusion    The evidence shows that endotherapy may be an effective treatment for early esophageal neoplasm when considering the long-term outcomes whether it is squamous or adenocarcinoma, even though it is not as effective as surgery in the short-term efficacy.

AIM:To analyse of refractive regression after laser in situ keratomileusis(LASIK)in moderate and high myopic eyes.

METHODS:A retrospective study. Thirty patients(60 eyes)with refractive regression after LASIK in our hospital from January 2016 to January 2018 were selected for statistical analysis. According to preoperative refraction, they were divided into three groups: moderate myopia group(<-6.00D), high myopia group(-6.00 to -10.00D)and super high myopia group(>-10.00D). The visual acuity, diopter, corneal curvature, CCT, intraocular pressure, ocular axis and residual corneal matrix thickness were analyzed before and after surgery.

RESULTS:The refractive regression rate was 8.6%(60/700 eyes). At 6mo after operation, the refractive regression of the patients were as follows: moderate myopia group, 1.31±0.15D, high myopia group, 1.76±0.23D, ultra-high myopia group: 2.53±0.35D(P<0.05). At 6mo after operation, the diopter(-0.82±0.21, -1.03±0.27, -1.57±0.52D)of the three groups was different from that of the preoperative(-4.87±0.97, -7.46±1.03, -10.32±2.01D)and 1mo(+0.49±0.22, +0.73±0.17, +0.95±0.15D)after operation(all P<0.05). At 6mo after operation, the CCT of the three groups(499.80±33.78, 458.89±36.93, 451.93±24.52μm)decreased(P<0.05)compared with that before operation(523.80±23.00, 527.24±25.47, 525.80±22.36μm), and increased(487.92±38.13, 440.65±33.92, 429.35±20.14μm). There was no difference in ocular axis(25.25±0.30, 26.52±0.62, 28.63±0.21mm)between the three groups at 6mo after operation and before operation(25.13±0.54, 26.13±0.54, 28.03±1.04mm)(P>0.05), but there was difference between the two groups(P<0.05). The thickness of residual corneal stroma in moderate myopia group, high myopia group and ultra-high myopia group were 332.27±21.87, 292.71±22.71 and 273.38±20.99μm, respectively(P<0.05). There was no difference in corneal curvature and intraocular pressure between the three groups at 6mo after operation(P>0.05).

CONCLUSION: The occurrence of refractive regression after LASIK is related to preoperative refraction. High myopia and ultra-high myopia may have refractive regression due to progressive growth of eye axis, while moderate myopia may have refractive regression due to increased corneal thickness and corneal curvature changes caused by post-operative matrix repair.

Objective: The aim of the present study was to evaluate the clinical outcomes of implant-supported prostheses for oral function rehabilitation in patients with ectodermal dysplasia. Methods : Thirteen patients were included in the present study. After bone augmentation, zygomatic implants (ZIs) or regular implants (RIs) were placed, fabrication of dental prostheses were applied, and psychological and oral education was carried out. Implant survival rates, patient satisfaction and other related evaluation indicators were assessed. Results: The ilium was chosen for autogenic bone grafts in two patients. The fibula was used in two other patients and the mandibular ramus in one other patient. One patient was treated through alveolar distraction osteogenesis of the mandible. Guided bone regeneration was applied in seven other patients. Bone graft resorption in the maxilla was observed in one patient; bone augmentation of the mandible was successful in all patients, and no obvious bone resorption was observed. One hundred and eighteen implants were placed, among which 22 were ZIs, and 96 were RIs. Five RIs failed and were removed. The survival rate for ZIs was 100%, and the survival rate for RIs was 94.79%, in a follow up after 3 years. All patients were satisfied with the restoration of their oral function. More than 50% of the patients exhibited self-confidence. Conclusion Oral function can be restored in edentulous ectodermal dysplasia patients using bone augmentation and implant-supported prostheses, and patient self-confidence can be enhanced. However, the resorption of grafted bone in the anterior region of the maxilla cannot be ignored.

Objective To investigate the effect of music therapy combined with routine medication and rehabilitation training on motor function of hand of patients with brain injury. Methods 30 brain injury patients with hemiplegia were divided into sound group (n=15) and no-sound group (n=15). Besides routine medication and rehabilitation training, two groups received instrument training, one for open music and the other for closed music, 30 minutes a day for 4 weeks. They were evaluated with Simple Test for Evaluating Hand Function (STEF) and Modified Barthel Index (MBI) before and after training to assess hand function and activities of daily living (ADL) respectively. Results The scores of STEF and MBI improved in both groups after training (P<0.01). The score of STEF was better in the sound group than in the no-sound group (P<0.01) while the score of MBI showed no difference between the two groups (P>0.05). The items as taking metal pieces, taking small balls, and taking small metal rod improved most in the sound group while the items as taking small cubic, taking small metal rod, and taking artificial leather improved most in the no-sound group. The items as dressing oneself, cleaning after defecating and urinating,and making up improved most in the two groups. Conclusion Music therapy combined with routine medication and rehabilitation training can facilitate to improve fine movement function of hand of hemiplegic patients, such as movement speed, precision.
