ABSTRACT

OBJECTIVES@#To observe the therapeutic effect of Tongyuan needling combined with jingyu herb-separated moxibustion on the patients with recurrent implantation failure (RIF) of kidney deficiency and blood stasis undergoing frozen embryo transfer of the conventional hormone replacement therapy cycle.@*METHODS@#Sixty RIF of kidney deficiency and blood stasis patients who planned for frozen embryo transfer were randomly divided into a combined treatment group (30 cases) and a western medication group (30 cases). In the western medication group, the conventional hormone replacement therapy was performed for endometrial preparation during transfer cycle. On the basis of treatment as the western medication group, in the combined treatment group, Tongyuan needling combined with jingyu herb-separated moxibustion was adopted. Regarding tongyuan needling, the acupoint prescription for Tongdu Tiaoshen (promoting the governor vessel and regulating the spirit, e.g. Dazhui [GV 14], Ganshu [BL 18], Shenshu [BL 23] and back-shu points) and that for Yinqi Guiguan (conducting qi back to the primary, e.g. Zhongwan [CV 12], Qihai [CV 6], Guanyuan [CV 4] and front-mu points) were selected. Acupuncture was delivered at these two prescriptions alternatively each time. After acupuncture, the herb-separated moxibustion (in which, the herbal powder was prepared with the modified Yangjing Zhongyu decoction for cultivating the kidney essence and promoting pregnancy) was operated at Shenque (CV 8). This combined therapy was delivered once every two days, 3 sessions a week till the day of embryo transfer. The pregnancy outcomes (positive rate of human chorionic gonadotropin [β-HCG] and clinical pregnancy rate) were compared between the two groups, as well as the TCM syndrome score, serum estradiol (E2) and progesterone (P) levels, endometrial thickness and type, endometrial blood flow index (pulsatility index [PI], resistance index [RI]) before and after treatment.@*RESULTS@#After treatment, the clinical pregnancy rate of the combined treatment group was 40.0% (12/30), higher than that of the western medication group (16.7%, 5/30, P<0.05); and the difference in the positive rate of β-HCG was not significant statistically between the two groups (P>0.05). After treatment, the serum levels of E2 and P were elevated (P<0.05), the endometrial thickness was thickened (P<0.05); the scores of TCM syndrome, and the levels of PI and RI were reduced (P<0.05) when compared with those before treatment in the two groups. The proportion of type A endometrium increased compared with that before treatment in the combined treatment group (P<0.05). Except the levels of E2 and P, the above indexes in the combined treatment group were superior to the western medication group (P<0.05).@*CONCLUSIONS@#On the basis of frozen embryo transfer of conventional hormone replacement cycle, the intervention of Tongyuan needling combined with jingyu herb-separated moxibustion can effectively relieve the clinical symptoms, increase the endometrial blood flow and its thickness, and improve the endometrial receptivity, thereby ameliorate pregnancy outcomes in RIF patients of kidney deficiency and blood stasis.

ABSTRACT

Objective To explore the effective constituents from Sonchus arvensis L. and the potential mechanism in treating sepsis by network pharmacology. Methods The chemical ingredients reported in the literature were taken as research objects and Swiss Target Prediction database was used to collect the identify the potential targets of those ingredients. The GeneCards, OMIM and TTD databases were applied to screen the sepsis related molecular targets. The cross targets were obtained and used to construct the active ingredient-disease target network. In addition, the targets were also imported into STRING database to construct a PPI network. Finally, GO and KEGG enrichment analysis were performed on the target genes to predict the mechanism via DAVID database. Results 71 components from S. arvensis L. were obtained, which corresponded to 579 potential drug targets. There were 3437 related targets of sepsis. S. arvensis L. and sepsis shared 272 common targets. The results showed that 1366 terms were found by GO function enrichment, including 245 molecular functions (MF), 1002 biological processes (BP), and 119 cell composition (CC), The KEGG enrichment analysis suggested that 166 signaling pathways were involved. Conclusion The study revealed that TNF, AKT1, IL-6, IL-1β, TP53 and some other targets might be affected by potentially active ingredients of S arvensis L. such as linoleic acid, linolenic acid and oleic acid to regulate the expression of steroids, sphingolipids hormones as well as epidermal factors and chemokines in treating sepsis.

ABSTRACT

Objective:To investigate the effect of subfibular ossicle excision on the clinical efficacy of Brostr?m procedure for chronic lateral ankle instability (CLAI).Methods:From March 2014 to December 2018, 76 patients were treated by the modified Brostr?m procedure using the suture anchor technique for CLAI at Department of Foot & Ankle Surgery, Wuhan Fourth Hospital. Of them, 33 had subfibular ossicles (SFO group) and 43 did not (NSFO group). In the SFO group, there were 19 males and 14 females, aged (28.4±8.6) years; in the NSFO group, there were 21 males and 22 females, aged (27.8±7.4) years. Subfibular ossicles were excised in the SFO group. The 2 groups were compared in terms of American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scores and visual analogue scale (VAS) pain scores at preoperation and the final follow-up.Results:The 2 groups were comparable due to insignificant differences between them in their preoperative general data ( P>0.05). All the patients were followed up for 24 to 72 months (average, 28 months). The AOFAS ankle-hindfoot scores improved significantly from 54.5±3.4 to 95.7±2.1 in the SFO group and significantly from 56.2±2.7 to 95.2±2.4 in the NSFO group at the final follow-up; the VAS scores reduced significantly from 5.7±1.8 to 1.6±1.4 in the SFO group and significantly from 5.7±1.6 to 1.7±1.2 in the NSFO group at the final follow-up (all P<0.05). No significant differences were found between the 2 groups in terms of AOFAS or VAS scores at the final follow-up ( P>0.05). Conclusion:Since the modified Brostr?m procedure plus subfibular ossicle excision may result in similar good clinical efficacy as merely the modified Brostr?m procedure may for the CLAI patients without subfibular ossicle, subfibular ossicle excision should be suggested for the CLAI patients with subfibular ossicle.

ABSTRACT

Objective:To investigate the effects of periacetabular osteotomy (PAO) in treating borderline developmental dysplasia of the hip (DDH).Methods:The patients with borderline DDH [lateral center-edge angle (LCEA): 18°-25°) who received PAO with follow-up duration for more than 2 years from January 2011 to January 2018 in our hospital were retrospectively analyzed. The patients in the control group were matched on a 1∶2 ratio based on gender, age, body mass index (BMI) and follow-up duration. There were 66 patients in the 0°≤LCEA<10° group and 66 patients in the 10°≤LCEA<18° group. The LCEA, anterior center-edge angle (ACEA), T?nnis angle, femoral head extrusion index, femoro-epiphyseal acetabular roof (FEAR) index, femoral anteversion angle, West Ontario and McMaster University (WOMAC) index and International Hip Outcome Tool (iHOT-12) were compared among the three groups before operation and the last follow-up.Results:In the preoperative 18°≤LCEA<25° group, three of 33 patients (9.1%) had LCEA, because the only imaging feature suggested acetabular dysplasia, while other parameters were evaluated within the normal range. There were 17 patients with ACEA <20° (51.5%), 24 patients (72.7%) with T?nnis angle >10°, 12 patients (36.4%) with ACEA <20° and T?nnis angle >10°. The positive rate of posterior wall signs in the 18°≤LCEA<25° group (72.7%) was lower than that in the 10°≤LCEA<18° group (77.3%) and the 0°≤LCEA<10° group (90.9%) with statistically significant difference (χ 2=6.417, P=0.040) at preoperation. The positive rate of cross sign (27.3%) and ischial spine sign (48.5%) in the 18°≤LCEA<25° group were higher than those in the 10°≤LCEA<18° group (10.6% and 18.2%, respectively, χ 2=7.002, P=0.030) and the 0°≤LCEA<10° groups (9.1% and 13.6%, respectively, χ 2=16.497, P<0.001). The FEAR index in the 18°≤LCEA<25° group (3.7±8.0) lower than that in the 10°≤LCEA<18° group (4.3±7.9) and the 0°≤LCEA<10° group (11.0±8.8) with significant difference ( F=12.703, P<0.001). In the 18°≤LCEA<25° group, postoperative LCEA increased from 20.4°±1.8° to 37.8°±7.1°, ACEA increased from 18.3°±7.8° to 36.3°±6.3°. T?nnis angle decreased from 12.7°±6.2° to -5.6°±9.2°, the femoral head extrusion index decreased from 22.9%±6.7% to 10.7%±12.2%, the WOMAC index decreased from 20.1±13.4 to 6.0±6.3, and the iHOT-12 score increased from 50.2±19.9 to 90.0±13.7. The above difference before and after surgery was statistically significant ( P<0.05). At the last follow-up, the WOMAC score in the 18°≤LCEA<25° group was 6.0±6.3, wich was less than 10°≤LCEA<18° group (9.3±9.6) and 0°≤LCEA<10° group (12.0±16.0) ( F=6.515, P=0.002). The iHOT-12 score in the 18°≤LCEA<25° group was 90.0±13.7, which was greater than 10°≤LCEA<18° group (77.7±17.3) and 0°≤LCEA<10° group (78.1±20.5) ( F=15.833, P<0.001). Conclusion:After 2 years follow-up, PAO significantly improved bone coverage of femoral head and hip function in patients with borderline DDH. Before surgery, we should pay attention to the comprehensive evaluation of different radiological parameters of the acetabulum, to make better preoperative planning.

ABSTRACT

Objective:To report our experience in the emergent foot and ankle surgery in the epidemic of COVID-19.Methods:The data of 18 patients with acute foot and ankle injury were reviewed who had been admitted to the Department of Foot and Ankle Surgery, Wuhan Fourth Hospital from 20th January, 2020 to 26th February, 2020. They were 11 men and 7 women, aged from 18 to 70 years (average, 42.5 years). There were 5 cases of acute open injury and 13 ones of acute closed injury. COVID-19 infection was diagnosed or suspected in 5 cases but not in the other 13 cases. Emergency operation was carried out for 2 patients with open injury plus COVID-19 infection and one with complicated pilon fracture plus COVID-19 infection, one of whom received secondary operation. One patient with closed fracture of the left calcaneus plus COVID-19 infection was hospitalized from emergency department for secondary surgery, and another with closed fracture of the right lateral malleolus was referred to the isolation ward after emergency plaster fixation. Of the 10 patients with closed injury but without COVID-19 infection, 3 received conventional secondary surgery after admission and the others conservative treatment at the outpatient department. Recorded were COVID-19 infections in the patients after admission and in the medical staff. The measures taken and experience in control and prevention of COVID-19 infection after outbreak of the epidemic were reviewed.Results:Of the 11 patients who had been hospitalized for foot and ankle injury in emergency, 5 were definitely diagnosed of or suspected of COVID-19 infection and 6 free of COVID-19 infection. During hospitalization, COVID-19 infection was confirmed in the 5 cases and no COVID-19 infection occurred in the other 6 patients. No COVID-19 infection occurred in the medical staff; no cross infection was observed between the patients and the medical staff.Conclusions:Reasonable strategies are advised to balance the foot and ankle surgery and epidemic prevention. A simplified management is not advised for all the cases. The operative procedures in emergent foot and ankle surgery should be optimized in line with the epidemic control and prevention principles to facilitate functional rehabilitation for the patients.

ABSTRACT

Objective@#To explore the impacts of the imaging positions on the sagittal tilt of the pelvis and the imaging parameters of the hip joint.@*Methods@#From December 2015 to October 2016, a total of 78 female DDH patients (DDH group) who received Bernese periarticular osteotomy were enrolled, aged 28.41±9.91 years (range 18-49 years) with 135 hips. There were 21 cases on one side and 57 cases on both sides. Another 26 female volunteers without spinal and hip disease were enrolled as the control group, aged 23.54±5.58 years (range 18-49 years) with 52 hips. X-ray films of the anterior and posterior pelvis were performed in both groups. The pelvic sagittal tilt was evaluated by measurement (pubic symphysis to sacrococcygeal distance, PSSC), with lateral center-edge angle of Wiberg (LCEA), Tönnis angle (TA), and Sharp angle (angle of Sharp, SA) assessed the degree of hip dysplasia and assessed the horizontal positional relationship between the femoral head and the acetabulum using tear drop distance (TD). All data were measured twice by two measurers independently. The correlation between hip parameters and X-ray position was analyzed.@*Results@#The average PSSC in the supine and standing positions of the control group were 53.73±16.22 mm and 36.45±14.21 mm, respectively with significant difference-17.28±8.07 mm (t=-10.913, P=0.000). The PSSC of the supine and standing positions of the DDH group were 56.76±13.54 mm and 48.62±15.44 mm, respectively with significant difference-8.13±13.02 mm (t=-5.516, P=0.000). The PSSC of the standing DDH group was larger than that in the control group. There was no significant difference in the PSSC between the two groups in the supine position. Furthermore, there were no significant difference in the supine and standing PSSC between the unilateral and bilateral DDH patients (P>0.05). In the control group, the hip in supine and standing position, LCEA averaged 30.33°±4.69° and 29.70°±3.83° (P>0.05), and TA averaged 4.05°±3.51° and 4.36°±3.07° (P>0.05), respectively. SA averaged 40.53°±4.34° and 41.79°±3.16° (P>0.05), and TD averaged 6.80±0.98 mm and 6.65±1.30 mm (P>0.05), respectively. In the DDH group, the hip in supine and standing positions, LCEA averaged 3.07°±12.07° and 1.69°±12.11° (P<0.05), and TA averaged 22.62°±9.31° and 23.82°±9.45° (P>0.05), respectively. SA averaged 48.01°±4.68° and 48.49°±4.74° (P>0.05), respectively, and TD averaged 10.51±3.51 mm and 10.93±4.23 mm (P>0.05), respectively.@*Conclusion@#From supine to standing, the pelvis backward is the main trend in sagittal plane. In standing, the pelvis of female DDH patients is forward contrast with normal women. There was no difference in pelvic tilt between unilateral and bilateral DDH patients. Female DDH patients from the supine to standing, hip coverage decreased, while the femoral head appeared horizontally outward. The hip joint of DDH patients is unstable.

ABSTRACT

Objective To report the short-term outcomes of the rotational osteotomy on the base of femoral neck in treating osteonecrosis of femoral head.Methods Ten patients (10 hips) with osteonecrosis of femoral head underwent the rotational osteotomy on the base of femoral neck between March 2014 and October 2016.There were 9 males and 1 female.The average age was 29.6 years,ranging from 18 to 42 years.There were 4 patients in right side and 6 in left side.The Association Research Circulation Osseous (ARCO) Stage was from ⅡB to ⅢC (2 cases of ⅡB,2 cases of ⅡC,1 case of ⅢA,1 case of ⅢB,4 cases of ⅢC).The following main procedures were involved in the treatment:surgical hip dislocation,the extension of retinacular soft-tissue flap to protect the main blood supply of the femoral head,anterior or posterior rotational (60°-90°) of femoral head after femoral neck osteotomy.We used three compress cannulated screws to fix the femoral neck osteotomy.The postoperative Harris hip scores (HHS),Western Ontario and McMaster College (WOMAC) score,pelvic A-P view and lateral hip view radiographic characteristics were analyzed to assess the short-term outcomes.Results The average follow-up duration was 16.3 months (7-36 months).No progressive femoral head collapse was observed in 6 patients at the last follow-up.The average post-operative intact ratio was 42.90%± 10.07%.The HHS improved from 80.00±14.93 to 86.83±6.11 (4 cases improved,1 case with no change and 1 case decreased slighdy).The WOMAC score decreased from 16.00±14.53 to 9.00±3.85 (1 cases increased,1 case with no change and 4 case decreased).The remaining 4 cases,however,had the progression of the femoral head collapse.The average post-operative intact ratio was 16.57%±6.57%.The HHS decreased from 77.75±14.66 to 60.75±17.54 (1 case improved slightly and 3 cases decreased).The WOMAC score increased from 12.75±5.06 to 22.50±8.81 (4 cases increased).Conclusion The rotational osteotomy on the base of femoral neck not only shifts the necrosis area away from weight-bearing region but also improves the post-operative intact ratio.Patients with ARCO stage ⅡB-ⅢB may achieve remission of symptoms and improvement of hip function by this surgical technique.However,for patients with ⅢC stage,we should conduct preoperative design to make sure whether the surgery is worth doing or not.Some patients may suffer from post-operative progression collapse of the femoral head.

ABSTRACT

Objective Studies are rarely reported on how to avoid complement system attack during the transplantation of bone marrow mesenchymal stem cells (BMSCs).We explored the effect of the overexpression of CD59 on complement membrane attack-induced damage to rat BMSCs (rBMSCs) during autologous transplantation.Methods BMSCs from SD rats were cultured and treated with CD59 overexpression plasmid or rBMSC empty vector or left untreated,followed by detection of the expression of CD59 in the rBMSCs by flow cytometry.Then the rBMSCs were incubated with autologous rat serum (ARS),inactivated ARS (iARS),CD59+ARS,or CD59+iARS or not incubated.The cytotoxicity of the serum complement on the rBMSCs was observed by PI staining and the apoptosis of the rBMSCs determined by flow cytometry.Results The expression of CD59 was significantly higher in the rBMSCs treated with CD59 than in those untreated (7,4.9% vs 50.5%,P<0.05).The apop tosis rate was remarkably lower in the rBMSCs not incubated ([8.4± 1.1] %) and those incubated with CD59+ARS ([19.1 ±3.1] %) than in those incubated with ARS ([40.3±4.3] %) (P<0.05).The deposition of the complement membrane attack complex was significantly decreased in the rBMSCs not incubated (50.1%) and those incubated with CD59+ARS (71.0%) as compared with those incubated with ARS (99.7%) (P<0.05).The apoptosis rate of the rBMSCs treated with CD59 was markedly lower than that of those left untreated (P<0.05).Conclusion The overexpression of CD59 inhibits the damage induced by complement to rBMSCs by reducing the formation of the complement membrane attack complex during autologous transplantation.

ABSTRACT

Objective · To investigate the histone methyltransferase capability of DOT1L-long form and its role in breast cancer metastasis.Methods · The existence of DOT1L-long form was confirmed by PCR, and the mRNA level of DOT1L was tested by real-time PCR. In HEK293T cells in which DOT1L canonical and DOT1L-long were overexpressed respectively, Western blotting was used to test the expression level of DOT1L and the histone methyltransferase capability. In the MCF10A cell line with inducible expression of DOT1L-long, real-time PCR was used to detect the mRNA level of epithelial-mesenchymal transition (EMT) marker, and transwell assay was used to detect the migration of breast cancer cells in which the expression level of DOT1L is low or high. Results · PCR demonstrated the existence of DOT1L-long form, and real-time PCR showed it widely exists in HCT116, T98G, MCF10A cells, etc. Western blotting showed the expression of DOT1L-long form and its H3K79 methyltransferase activity. In MCF10A cells in which overexpressed canonical DOT1L and DOT1L-long, mRNA levels of N-cadherin and fibronectine increased. Transwell showed canonical DOT1L and DOT1L-long both substantially increased the migration of breast cancer cells. Conclusion · The existence of DOT1L-long was confirmed and investigated, which is 202 amino acids longer than the canonical DOT1L, and is coded by a new exon, located between exon 27 and 28. Further, the DOT1L-long has H3K79 methyltransferase activity, and is able to promote breast cancer metastasis.

ABSTRACT

Objective To investigate the clinical efficiency and safety of femoral head reduction osteotomy for young patients with coxa magna or coxa plana.Methods Between June 2012 and September 2015,the clinical characteristics of 12 patients (13 hips) with coxa magna or coxa plana who underwent femoral head reduction osteotomy were analyzed retrospectively.There were 6 males (7 hips) and 6 females (6 hips) with average age 18.1 years (range,10-25 years).The etiology of the femoral head deformity was multiple epiphyseal dysplasia in 6 hips and Legg-Calvé-Perthes sequela in 7 hips.The head reduction osteotomy was conducted through the surgical hip dislocation approach combined with extended retinacular soft-tissue flap extending technique.All patients underwent simultaneous periacetabular osteotomy and relative lengthening of the femoral neck,of which four also underwent proximal femur derotational osteotomy.All patients received the standardized rehabilitation procedures.The postoperative complications,gaits,the range of motion (ROM) of the hip,Harris hip scores,iHOT scores and VAS were analyzed postoperatively.In addition,the lateral center-edge (LCE) angle,sphericity index and coverage rate of femoral head were assessed as well.Results The average follow-up duration was 28.8 months (range,12-45 months).All patients achieved osteotomy healing of the femoral head and greater trochanter with average healing time 3.7 months (range,3-7 months).Nine of 12 patients had significant gaits improvement.The Harris hip scores (81.08± 12.36 vs.88.38 ± 8.96,t=2.41,P=0.033),iHOT score (51.90± 15.07 vs.67.69±8.70,t=3.63,P=0.003),LCE angle (-1.82°±16.57° vs.36.02°±7.72°,t=10.52,P=0.000),sphericity index of anteroposterior pelvic radiographs (71.08%± 10.32% vs.81.22%±8.61%,t=7.17,P=0.000) and the coverage index (48.79%±11.85% vs.87.46%± 10.44%,t=8.56,P=0.000) were all significantly improved when compared to those preoperatively.The VAS score (4.46± 2.37 vs.1.23±0.93,t=4.25,P=0.001) was significantly decreased when compared with that preoperatively.However,for the sphericity index of 65° false profile (78.96%± 10.39% vs.80.36%±8.42%,t=0.411,P=0.688) and the average hip ROM (264.62°± 32.05° vs.255.00°±40.31°,t=0.89,P=0.391),they did not achieve statistical significant difference.One case of femoral head necrosis site was localized at the lateral-superior part of femoral head,and there was no progression after 3 years follow-up.Moreover,no revision or total hip arthroplasty were observed due to other complications (osteoarthritis,hip pain or non-union).Conclusion The femoral head reduction osteotomy can correct deformity,improve femoral head sphericity,relieve pain and improve gaits and hip function.This procedure leads to satisfied clinical outcomes for patients with coxa magna or coxa plana in early follow-up.
