Comparative study of different clinical approaches for gluteal muscle syndrome with silver needle / 中国骨伤

OBJECTIVE@#To explore the clinical efficacy of silver needle lumbar and sacral spine approach in treating gluteal muscle syndrome.@*METHODS@#Eighty-seven patients with gluteal muscle syndrome treated with silver needles in the Department of Rehabilitation Medicine of our hospital from September 2017 to September 2019 were selected. Except for symptoms of waist and hip pain and discomfort, all selected patients were examined by CT or MRI to confirm pathological imaging changes such as inflammatory exudation of the gluteal muscle. The 87 patients with gluteal muscle syndrome were divided into 2 groups according to the digital table method, and 42 patients in the lumbosacral approach group, including 19 males and 23 females, aged (50.70±12.45) years old, and disease duration of (1.63±1.27) years;45 cases in the buttock approach group, including 20 males and 25 females, aged (52.80±12.18) years old, with a course of disease of (1.78±1.22) years. The lumbosacral approach group was treated with spinal L to S bilateral articular process joints and L transverse process acupuncture needles, and the buttock approach group was treated with the gluteus medulla wing starting point and femoral trochanter stop. The VAS scores, soft tissue tenderness thresholds, and hip abductor muscle strength of the affected group were measured before and 4 weeks after treatment in the two groups. The clinical efficacy was also evaluated 4 weeks after treatment.@*RESULTS@#After 4 weeks, the VAS score of the lumbosacral approach group was 1.26±0.70, and the buttock approach group was 1.18±0.74, which were significantly lower than those before treatment, but there was no statistical difference between the groups (>0.05). The soft tissue tenderness threshold and ipsilateral hip abductor muscle strength were (5.51±0.70) kg and (10.34±2.19) kg in the lumbosacral approach group, and (4.78±1.05) kg, (9.33±1.42) kg in the buttock approach group. The results in the lumbosacral approach group was better than those in the buttock approach group(<0.05). The clinical efficacy of the lumbosacral approach group:16 cases got an excellent result, 20 good, 5 fair and 1 poor;in the buttock approach group, 13 excellent, 17 good, 12 fair and 3 poor. The clinical efficacy between the two groups had statistical difference (<0.05).@*CONCLUSION@#In the treatment of gluteus medius syndrome with silver needle, lumbosacral approach and buttock approach can effectively relieve the pain. Compared with the improvement of soft tissue tenderness threshold and hip abductor muscle strength, the upper lumbosacral approach is more prominent, and the overall clinical effect is more significant.

Value of preoperative localization techniques for solitary pulmonary nodules in singleport thoracoscopic surgery / 南方医科大学学报

To evaluate the value and clinical effect of different preoperative localization techniques for solitary pulmonary nodules (SPN) before single-port thoracoscopic surgery.From January 2018 to June 2019, 54 patients diagnosed with solitary pulmonary nodules received single-port thoracoscopic surgery in Thoracic Department of General Hospital of Southern Theater Command of PLA. Based on the location methods of the nodules, the patients were divided into group A (34 cases) with preoperative CT-guided Hook-wire (a common positioning needle usually using in mammary gland) positioning and group B (20 cases) with preoperative CT-guided methylene blue location.The success rate of localization in group A was 94.18% (32/34), significantly higher than that in group B [85% (17/20), < 0.05). No intraoperative conversion to thoracotomy occurred in group A, while the conversion rate was 10% (2/20) in group B ( < 0.05). The average positioning cost was significantly higher in group A than in group B (1715±109 1021±86 RMB yuan, < 0.05), but the total hospitalization cost was similar between the two groups (50 114±3788 47871±5902 RMB yuan, >0.05). The length of hospital stay was significantly shorter in group A than in group B (6.71±1.23 8.19±2.61 days, < 0.05).Compared with the traditional methylene blue localization method, Hook-wire localization positioning can significantly increase the success rate of localization, and can be used as the standard preoperative localization method in patients undergoing single-port thoracoscopic pulmonary nodule resection, especially in those with deep nodule location from the visceral pleura.

Best bone of acetabulum for cup component placement in Crowe types I to III dysplastic hips: a computer simulation study / 中华医学杂志(英文版)

BACKGROUND@#During cup implantation, vertical height of the cup center (V-HCC) should be precisely controlled to achieve sufficient bone-cup coverage (BCC). Our study aimed to investigate the acetabular bone stock and the quantitative relationship between V-HCC and BCC in Crowe types I to III hips.@*METHODS@#From November 2013 to March 2016, pelvic models of 51 patients (61 hips) with hip dysplasia were retrospectively reconstructed using a computer software. Acetabular height and doom thickness were measured on the mid-acetabular coronal cross section. V-HCC was defined as the vertical distance of cup rotational center to the interteardrop line (ITL). In the cup implantation simulation, the cup was placed at the initial preset position, with a V-HCC of 15 mm, and moved proximally by 3-mm increments. At each level, the BCC was automatically calculated by computer. Analysis of variance and Kruskal-Wallis test were used to compare the differences between groups.@*RESULTS@#There were no significant between-group differences in maximum thickness of the acetabular doom; however, peak bone stock values were obtained at heights of 41.63 ± 5.14 mm (Crowe type I), 47.58 ± 4.10 mm (Crowe type II), and 55.78 ± 3.64 mm (Crowe type III) above the ITL. At 15 mm of V-HCC, median BCC was 78% (75-83%) (Crowe type I), 74% (66-71%) (Crowe type II), and 61% (57-68%) (Crowe type III). To achieve 80% of the BCC, the median V-HCC was 16.27 (15.00-16.93) mm, 18.19 (15.01-21.53) mm, and 24.13 (21.02-28.70) mm for Crowe types I, II, and III hips, respectively.@*CONCLUSION@#During acetabular reconstruction, slightly superior placement with V-HCC <25 mm retained sufficient bone coverage in Crowe I to III hips.

Radiographic Measurement of Femoral Lateral Bowing and Distal Femoral Condyle Resection Thickness: Variances and Effects on Total Knee Arthroplasty Planning / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Accurate evaluation of the plain radiography of lower limb is critical for preoperative planning of total knee arthroplasty (TKA). We aimed to investigate the effect of femoral lateral bowing and rotation on the radiographic measurements of distal femoral condyle resection thickness (DRT) and the distal femoral resection valgus angle (FVA).</p><p><b>METHODS</b>We analyzed 246 three-dimensional femoral models generated from computed tomography images of 123 patients, acquiring projected contours in seven positions - 20° and 10° internal rotation; 0° rotation; 10°, 20°, 30°, and 40° external rotation - for each model. Medial and lateral condyle DRTs, femoral shaft lateral bowing angle (FBA), and distal FVA were determined for each position. Linear mixed effect model was used to determine the effect of degree of femur rotation on repeated measurements of DRT or FVA.</p><p><b>RESULTS</b>FBA significantly affected the FVA and DRT (Pearson's R = 0.767 and -0.408, respectively; P < 0.000). Samples were divided into three groups according to the FBA measured in neutral position: FBA <0°: DRT 3.75 ± 1.30 mm, FVA 4.53° ± 1.27°; FBA >0° but <3°: DRT 3.39 ± 1.31 mm, FVA 5.92° ± 1.31°; FBA >3°: DRT 2.22 ± 1.31 mm, FVA 7.37° ± 1.31°. From simulated 20° internal rotation to 40° external rotation in each femoral model, the average variation ranges of radiographically measured DRT, FVA, and FBA were 0.50 ± 0.28 mm, 2.93° ± 0.96°, and 10.33° ± 1.90°, respectively, with no significant differences among the FBA groups. The degree of femoral rotation significantly affected the FVA (F = 62.148, P < 0.000), whereas there was no effect on condyle resection thickness (F = 0.4705, P = 0.494).</p><p><b>CONCLUSIONS</b>Axial femoral rotation has less effect on radiographic measurements of differences in the DRT than on those of the distal FVA.</p>

Ceramic-on-ceramic versus ceramic-on-polyethylene bearing surfaces in total hip arthroplasty：a meta analysis of efficacy and safety / 中国组织工程研究

BACKGROUND: Greatly importance has been attached to ceramic-on-ceramic bearing surface due to its excel ent wear resistance. But the risks of squeaking and ceramic fracture also go with it. Up til now, the choice between ceramic-on-ceramic and ceramic-on-polyethylene bearing surfaces in primary total hip arthroplasty remains controversial. OBJECTIVE: To compare the clinical outcomes and safety between ceramic-on-ceramic versus ceramic-on-polyethylene bearing surfaces in total hip arthroplasty based on meta analysis. METHODS: We electronical y searched databases including PubMed/Medline, Embase, Web of Science, Cochrane Col aboration database, Chinese Biomedical Literature Database (CBMdisc) and China National Knowledge Internet for randomized control ed trials on the comparison between ceramic-on-ceramic versus ceramic-on-polyethylene bearing surfaces in total hip arthroplasty from inception to January 2015. References of the included studies were also retrieved. Investigators severely selected the studies, extracted data and assessed the quality according to the inclusion and exclusion criteria. Then, meta-analysis was performed using RevMan 5.2 software. RESULTS AND CONCLUSION: Nine randomized control ed trials were included, involving 1 231 hips with ceramic-on-ceramic prosthesis and 932 hips with ceramic-on-polyethylene prosthesis. Meta analysis showed that both bearing surfaces achieved satisfied function recovery. But ceramic-on-ceramic had significantly increased risks of squeaking and ceramic fracture, meanwhile ceramic-on-polyethylene showed significantly higher wear rate. There were no significant differences in intra- or post-operative dislocation, osteolysis and other complications and prosthesis failure with any reason between two bearing surfaces. These results suggest that during the short- to mid-term fol ow-up period, no sufficient evidence can tel that ceramic-on-ceramic was obviously super than ceramic-on-polyethylene. Long-term fol ow-up is required for further evaluation.

The multivariate logistic regression analysis revealed that infection during early pregnancy (OR=18.776) and male neonates (OR=9.304) were risk factors for congenital anal atresia, and oral administration of folic acid during early pregnancy was the protective factor (OR=0.086).</p><p><b>CONCLUSIONS</b>Infection during early pregnancy is the risk factor for congenital anal atresia, and male neonates are more likely to develop congenital anal atresia than female neonates. Supplementation of folic acid during early pregnancy can reduce the risk of congenital anal atresia.</p>

Preoperative Measurement of Tibial Resection in Total Knee Arthroplasty Improves Accuracy of Postoperative Limb Alignment Restoration / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Accuracy of implant placement in total knee arthroplasty (TKA) is crucial. Traditional extramedullary alignment instruments are fairly effective for achieving the desired mean tibial component coronal alignment. We modified the traditional tibial plateau resection technique and evaluated its effect on alignment restoration.</p><p><b>METHODS</b>Two hundred and eighty-two primary TKAs in our hospital between January 2013 and December 2014 were enrolled in this retrospective study. Group A consisted of 128 primary TKAs performed by one senior surgeon. Preoperative measurement of the tibial resection was conducted on radiographs, and the measured thicknesses of the lateral and medial plateau resection were used to place the tibial alignment guide. Group B consisted of 154 primary TKAs performed by the other senior surgeon, using a traditional tibial plateau resection technique. In all patients, an extramedullary guide was used for tibial resection, and preoperative and postoperative full-leg standing radiographs were used to assess the hip-knee-ankle angle (HKA), femoral component alignment angle (FA), and tibial component alignment angle (TA). A deviation ≥3° was considered unsatisfactory. Data were analyzed by unpaired Student's t-test.</p><p><b>RESULTS</b>The mean postoperative HKA and TA angles were significantly different between Groups A and B (178.2 ± 3.2° vs. 177.0 ± 3.0°, t = 2.54, P = 0.01; 89.3 ± 1.8° vs. 88.3 ± 2.0°, t = 3.75, P = 0.00, respectively). The mean postoperative FA was 88.9 ± 2.5° in Group A and 88.9 ± 2.6° in Group B, and no significant difference was detected (t = 0.10, P = 0.92). There were 90 (70.3%) limbs with restoration of the mechanical axis to within 3° of neutral alignment and 38 (29.7%) outliers (>3° deviation) in Group A, whereas there were 89 (57.8%) limbs with restoration of the mechanical axis to within 3° of neutral alignment and 65 (42.2%) outliers (>3° deviation) in Group B. The severity of the preoperative alignment deformity was a strong predictor for postoperative alignment.</p><p><b>CONCLUSIONS</b>Using conventional surgical instruments, preoperative measurement of resection thickness of the tibial plateau on radiographs could improve the accuracy of conventional surgical techniques.</p>

Sero-prevalence of antibodies against avian influenza virus among people in poultry occupations in Guangdong province / 中华微生物学和免疫学杂志

Objective To detect the positive rates of antibodies against avian influenza virus (AIV) subtypes H5, H6, H7 and H9 among people in poultry occupations in Guangdong province and to analyze the transmission of various subtypes of AIV from poultry to human contacts for the prevention and control of novel AIV infection in human beings.Methods Serum specimens were collected from 1066 peo-ple in poultry occupations ( occupational group) and 205 people not in poultry occupations ( non-occupational group) in 10 cities of Guangdong province.The inactivated AIV strains, isolated from poultry or environment of Guangdong province, were used as antigens to detect antibodies against AIV subtypes H5, H6, H7 and H9 by using the hemagglutination inhibition ( HI) assay.Results The positive rates of antibodies against AIV subtypes H5, H6, H7 and H9 carried by people from the occupational group were respectively 0.44%, 0%, 0.30%and 0.30%in 2013 and 1.08%, 0.0%, 0.0%and 0.27%in 2014.Only the anti-H9 anti-bodies were detected in serum samples collected form people in the non-occupational group in 2013 with a positive rate of 0.95%.No significant differences with the positive rates of anti-AIV antibodies were found between the occupational group and the non-occupational group.However, the geometric mean titer ( GMT) of anti-AVI antibodies in people from the occupational group was higher than that of the non-occupational group.Conclusion Although a grand spread of AIV from avian to human is not likely to happen yet, con-tacting with poultry is the risk factor for AIV infection in Guangdong population.A long-term surveillance of anti-AIV antibodies in serum should be strengthened among people in poultry occupations for the timely pre-vention and control of novel AIV outbreak.

On the contrary, crude FYD extract promoted the proliferation and did not induce cell apoptosis.</p><p><b>CONCLUSION</b>The results by serum pharmacology were accordant with those of our previous animal and clinical trials which indicates that serum pharmacology is a reasonable and feasible method for the evaluation of the antitumor effect of herbs of Fuzheng Guben.</p>

Comparison of efficacy and safety between two kinds of injection therapy in the treatment of I-II degree rectal prolapse / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To explore the safety and efficacy of Shaobei injection in the management of I(-II( degree rectal prolapse.</p><p><b>METHODS</b>A total of 80 patients eligible for the inclusion criteria were divided into 2 groups: 40 patients in the treatment group (treated with Shaobei injection) and 40 cases in the control group (treated with Xiaozhiling) respectively. The short-term efficacy was identified by the length of rectal prolapse and the depth of rectocele demonstrated by the defecography while the long-term efficacy was evaluated by the length of rectal prolapse. In addition, the safety was assessed by the occurrence of postoperative complications.</p><p><b>RESULTS</b>The variation of the lengths of rectal prolapse and the depth of rectocele demonstrated by the defecography at the sixth month follow up in the two groups did not reach significant difference (P>0.05). After 2 year follow up, 37 patients (92.5%) in the treatment group and 35 cases(87.5%) in the control group was cured. Therefore, there was no significant difference in the long term efficacy between the two groups (P>0.05). The adverse events in the therapy group(10%) was less than that in the control group (45%)(P<0.01).</p><p><b>CONCLUSIONS</b>Shaobei injection in the management of I(-II( degree rectal prolapse has a similar efficacy of short-term and long-term higher safety compared to Xiaozhiling injection.</p>

Detecting acetylated proteins by affinity chromatography column / 中华血液学杂志

<p><b>OBJECTIVE</b>To establish a rapid, relatively quantitative method of detecting acetylated proteins.</p><p><b>METHODS</b>The proteins of Jurkat cells were acetylated by Trichostatin A (TSA) at different concentrations, then enriched and purified by anti-acetylated lysine antibodies affinity chromatography colum. The components eluted by acid were fixed on the microplate, the levels of acetylated proteins were tested by ELISA, and their components were identified by MALDI-TOF-TOF mass spectrometry. Also the above-mentioned methods were applied to the other three agents (gallic acid, emodin and monoacetylated emodin A).</p><p><b>RESULTS</b>That 4 × 10(5) Jurkat cells treated with 1 µmol/L TSA produced the optimal acetylated effect, up to 22 acetylated proteins were identified by MALDI-TOF-TOF, of them 15 were acetylated histones. The other three agents also induced acetylation, the relative values of acetylated proteins of Jurkat cells treated with 35.09 µmol/L and 17.54 µmol/L gallic acid were 4.3% and 14.2% respectively; those as of 28.7% and 11.5% treated with 1.47 µmol/L and 2.94 µmol/L emodin; those as of 22.0% and 3.6% treated with 152.91 µmol/L and 30.58 µmol/L monoacetylated emodin A.</p><p><b>CONCLUSION</b>The method based on affinity chromatography colum may be useful for the detection of acetylated proteins, and could be used to screen agents which target to histone deacetylase.</p>

Long-term efficacy of low dose leflunomide in the treatment of rheumatoid arthritis / 中国综合临床

Objective To perspectively evaluate the long-term efficacy of low dose leflunomide in treatment of rheumatoid arthritis.Methods Twenty-eight patients with rheumatoid arthritis were randomly divided into treatment group( n =15 ) and control group ( n =13 ).The patients in treatment group were treated with low dose leflunomide( omitting the loading dose) and with maintenance dose of 10 mg/day.And the patients in control group were treated with sulphasalazine in the dose of 1.5 ～ 2.0 g/d.The observation lasted for 18 months and the observed indicator were as follows:( 1 ) The primary efficacy indicators:counts of swollen and tender joints,overall assessment of disease status made by patients and physicians; ( 2 ) Secondary efficacy indicators:pain visual analogue scale,duration of morning stiffness,health assessment questionnaire (HAQ),Creaction protein,the American College of Rheumatology Outcome Assessment (ACR20,50).Results Eighteen months after treatment,the primary efficacy indicators in the treatment group were superior to the control group ( swollen joint counts:( - 8.5 ± 6.3 ) vs ( - 7.9 ± 6.4) ; overall assessment by patients:( - 1.4 ± 0.8 ) points vs ( - 1.2 ± 0.6) points; overall assessment by physicians:( - 1.4 ± 1.2 ) points vs ( - 1.3 ± 0.9 ) points; P ＜0.01 ).In the secondary efficacy indicators,pain visual analogue scale,duration of morning stiffness and health assessment questionnaire(HAQ) in the treatment group were significantly improved compared with the control group(VAS score:( - 32.4 ± 23.7) points vs ( - 31.6 ± 24.8) points; duration of morning stiffness:( [ - 97.8 ± 6.2 ] min vs [ - 92.4 ± 5.2 ] min; HAQ:[ - 0.62 ± 0.08 ] points vs [ - 0.57 ± 0.02 ] points,P ＜0.01 ),there was no significant difference on the percentage of patients achieving ACR20 standard between the treatment group and the control group (76.9％ vs 75.0％,P ＞ 0.05 ),but there was significant difference on the percentage of patients achieving ACRS0 standard between the treatment group and the control group( 61.5％ vs 47.0％,P ＜ 0.05 ).The gastrointestinaladverse reactions for patients in the treatment group were mild and there were 2 cases of elevated blood pressure,2 cases of elevated liver enzymes and 2 cases out of the trail,in the control group,there was 1 case out of the trial.Conclusion The long-term treatment of active rheumatoid arthritis with low dose leflunomide can achieve exact efficacy and good tolerability compared with the treatment with sulfasalasine.
