Case report and literature review: Fabry disease misdiagnosing as polymyalgia rheumatica.

RATIONALE: The clinical manifestations of Fabry disease affect the nerves, kidneys, heart, skin, gastrointestinal tract and eyes. Our aim is to familiarize people with the FD diagnostic process by reporting this case. PATIENT CONCERNS: A 79-year-old-male patient presented with muscle pain and weakness in the extremities, also with an increasing erythrocyte sedimentation rate and C-reactive protein. Further examinations revealed that multiple organ involvement, such as rash, myocardial hypertrophy, peripheral neuropathy. DIAGNOSES: Cardiac MR demonstrated hypertrophic cardiomyopathy, myocardial fibrosis and low myocardial T1 value. The patient was eventually diagnosed with Fabry disease through proteomics and genetic testing. INTERVENTIONS: The treatment is enzyme replacement therapy (ERT). But this patient could not afford ERT and was given only general symptomatic treatment, pregabalin, and a gradual reduction in glucocorticoid. OUTCOMES: The patient's symptoms of joint pain and muscle weakness reduced significantly, and ESR and CRP had decreased to normal. LESSONS: FD is a rare disease and difficult to diagnose, but rare does not mean invisible. FD may present with signs and symptoms of rheumatic diseases. Rheumatologists should be aware and concerned about this disease.

Exosomes from miR-23 Overexpressing Stromal Cells Suppress M1 Macrophage and Inhibit Calcium Oxalate Deposition in Hyperoxaluria Rat Model.

Purpose: To investigate whether ADSC-derived miR-23-enriched exosomes could protect against calcium oxalate stone formation in a hyperoxaluria rat model. Methods: An ethylene glycol- (EG-) induced hyperoxaluria rat model and an in vitro model of COM-induced HK-2 cells coculturing with RAW264.7 cells were established to explore the protective mechanisms of ADSC-derived miR-23-enriched exosomes. Results: The results showed that treatment with miR-23-enriched exosomes from ADSCs protected EG-induced hyperoxaluria rats, and cell experiments confirmed that coculturing with miR-23-enriched exosomes alleviated COM-induced cell autophagy. Overexpressed miR-23 suppressed M1 macrophage polarization by inhibiting IRF1 expression. Furthermore, the predicted binding site between the IRF1 messenger RNA 3'-untranslated region (3'-UTR) and miR-23 was confirmed by the dual-luciferase reporter assay. Conclusion: In conclusion, our research gave the first evidence that ADSC-derived miR-23-enriched exosomes affected the polarization of M1 macrophages by directly inhibiting IRF1 and protecting against calcium oxalate stone formation in a hyperoxaluria rat model.

ObjectiveTo observe the effects of Internet plus continuous rehabilitation nursing on older patients after lumbar fusion. MethodsFrom January, 2018 to August, 2021, 157 older patients after transforaminal lumbar interbody fusion (TLIF) in Department of Orthopedics, Chongqing General Hospital were retrospectively studied. A total of 66 patients accepting routine continuous rehabilitation nursing care were as control group, and 91 patients accepting internet plus continuous rehabilitation nursing care were as intervention group. They were assessed with Visual Analog Scale for pain (VAS), Oswestry Disability Index (ODI), Huaxi Emotional-distress Index (HEI) and Adult Health Self-management Skill Rating Scale (AHSMSRS) before, and one and three months after intervention. The compliance and nursing satisfaction were investigated with self-made questionnaire three months after intervention, and the postoperative complications were recorded. ResultsA total of 148 patients finished follow-up of three months, including 61 patients for the control group and 87 patients for the intervention group. The VAS, ODI, HEI and AHSMSRS scores improved in both groups one and three months after intervention (F > 85.4, P < 0.001), and improved more in the intervention group than in the control group (|t| > 3.645, P < 0.001). Both the compliance and nursing satisfaction were better in the intervention group than in the control group (χ2 > 5.478, P < 0.05), and no postoperative complication was observed in both groups. ConclusionInternet plus continuous rehabilitation nursing can promote the recovery of function, pain and psychological emotion, ability of self-management, compliance, and nursing satisfaction.

Antiphospholipid antibodies and osteonecrosis in systemic lupus erythematosus: a meta-analysis.

Objectives: The present meta-analysis aimed to assess the relationship between antiphospholipid antibodies (aPLs) or antiphospholipid antibody syndrome (APS) and the incidence of osteonecrosis (ON) in systemic lupus erythematosus (SLE) patients.Methods: MEDLINE/Pubmed, EMBASE, Web of science, the Chinese Biomedical Literature Database (CBM), the Wan-Fang Database, and the China National Knowledge Infrastructure (CNKI) were searched from their inception up until 26 December 2020. Studies in English were included. Case-control studies and cohort studies were included. Studies pertaining to the link between aPLs or APS and ON patients were slated for inclusion in the current analysis.Results: Twenty-two studies involving a total of 3054 SLE patients were included. The positivities of anticardiolipin antibody (ACL), IgG ACL, IgM ACL, LA and APS in SLE is not associated with ON. One study showed that IgG or IgM ß2GP1 had no association with ON. No publication bias was detected. The quality of this evidence was low because of the high risk of bias across studies, and therefore robust inferences cannot be made.Conclusion: SLE patients demonstrated a weak association between aPLs and ON. The nature of the association between aPLs and ON in SLE needs to be investigated in-depth in future research.

Application of percutaneous transluminal septal branch microsphere embolization in the treatment of hypertrophic obstructive cardiomyopathy / 中华急诊医学杂志

Objective:To compare the clinical efficacy and safety of percutaneous transluminal septal branch anhydrous alcohol ablation (PTSAAA) and percutaneous transluminal septal branch microsphere embolization (PTSBME) in the treatment of patients with symptomatic hypertrophic obstructive cardiomyopathy.Methods:The clinical data of 55 patients with symptomatic hypertrophic obstructive cardiomyopathy treated by PTSAAA and PTSBME were retrospectively analyzed, among whom 27 were treated with PTSAAA and 28 with PTSBME. The changes of postoperative indicators of the two groups of patients were compared, including the improvement degree of symptoms [shortness of breath after activity (cardiac function NYHA classification), chest tightness, chest pain (angina CCS classification) and amaurosis, the decrease of left ventricular outflow tract pressure gradient (LVOTPG)], the ventricular septum thickness shown by color Doppler echocardiography, the incidences of complications at postoperative month 6 and 12, and the incidences of cardiovascular events at follow-up month 12. LSD- t, χ 2 or Fisher exact probability methods were used to compare the differences of indicators between the two groups. Results:Compared to the relative indicators before operation, there were significant differences in shortness of breath after activity, chest pain and amaurosis, LVOTPG, ventricular septum thickness, the incidences of complications at postoperative month 6 and 12 and the incidences of cardiovascular events at follow-up month 12 in both the PTSAAA group and PTSBME group ( P<0.05). The PTSBME group was not inferior to the PTSAAA group in the improvement degree of amaurosis, cardiac function NYHA classification and angina CCS classification and left ventricular ejection fraction (LVEF) at postoperative month 6 and 12 ( P>0.05) as well as in the LVOTPG decrease and the ventricular septum thickness at postoperative month 6 [(16.8±7.5) mmHg vs (15.8±7.3) mmHg, (19.8±4.9) mm vs (17.4±4.1) mm, P>0.05], but was superior to the PTSAAA group in the LVOTPG decrease and the ventricular septum thickness at postoperative month 12 [(15.2±6.7) mmHg vs (9.8±5.4) mmHg, (18.4±5.1) mm vs (12.2±3.2) mm, P<0.05]. There were statistical significances in the incidences of cardiovascular events and third degree atrio-ventricular block and nosocomial mortality between the two groups (6 vs 1; 5 vs 0, P<0.05), and the PTSBME group was superior to the PTSAAA group in safety. Conclusion:PTSBME may be a safe and effective method for the management of patients with symptomatic hypertrophic obstructive cardiomyopathy.

Objective:To investigate the efficacy of robot-assisted laparoscopic surgery in heminephrectomy in children.Methods:The clinical data of 54 children with heminephrectomy in the First Affiliated Hospital of Zhengzhou University from January 2017 to December 2019 was analyzed retrospectively, of which 42 cases underwent laparoscopic heminephrectomy (LH group) and 12 cases underwent robot-assisted laparoscopic heminephrectomy (RALH group). In LH group, there were 17 males and 25 females, with an average age of (71.74±34.57)months, 29 on the left and 13 on the right. In RALH group, there were 4 males and 8 females, with an average age of (76.83±37.33) months, 9 on the left and 3 on the right. There was no significant difference in age, sex composition and deformity side between the two groups ( P > 0.05). The clinical indexes such as operation time, intraoperative blood loss, postoperative drainage time, hospital stay and postoperative complications were compared between the two groups. Results:There were significant differences in operation time[(196.48±21.92)min vs.(171.50±24.91)min], intraoperative blood loss[(34.14±8.63)ml vs.(18.50±5.92)ml], postoperative drainage time[6.0(5.0, 7.0)d vs. 4.5(3.0, 6.5)d] and postoperative hospital stay[(8.93±1.70)d vs.(7.33±1.37)d] between LH and RALH groups ( P < 0.05). During the follow-up from 3 months to 2 years, the lower kidneys of the two groups developed well and the symptoms before operation such as urinary tract infection, intermittent voiding leakage and dysuria caused by ureterocele were gradually relieved and disappeared after operation. In the LH group, 2 cases were complicated with the symptoms as ureteral stump effusion, cyst formation and recurrent ureteral stump infection after operation, which were cured after reoperation. There was no case of ureteral stump effusion and cyst formation in the RALH group. Conclusions:Robot-assisted laparoscopic heminephrectomy in children has shorter intraoperative blood loss, postoperative drainage time and hospital stay, lower incidence of postoperative complications, and has better efficacy and safety.

Comparison of emergency versus selective surgical operations for extra-articular fractures of distal radius complicated with dorsal displacement and comminuted metaphysis in elderly females / 中华创伤骨科杂志

Objective To compare the functional outcomes between emergency operation and delayed selective operation for extra-articular fractures of distal radius complicated with dorsal displacement and comminuted metaphysis in elderly females.Methods Included for this study were 60 elderly female patients who had been treated at Department of Orthopedic Trauma,The Second People's Hospital of Shenzhen from March 2016 to March 2017 for extra-articular fractures of the dorsally displaced distal radius with a volar locking plate.They were all female,aged from 65 to 80 years (average,73.8 years).Of them,30 received surgical operation on the day or the next day after injury (emergency group) and the other 30 did 5 to 15 days after surgery (mean,8 days) (selective group).Follow-ups were conducted at 4,12 and 48 weeks after surgery to assess the ranges of motion (ROMs) of the wrist and forearm,grip strength (GS),the Disability of Arm,Shoulder and Hand (DASH) scores and complications.Results The 2 groups were comparable because there were no significant differences between them in their preoperative general data (P ＞ 0.05).A 4 weeks after operation,the ROMs,GS and DASH scores were all significantly improved in both groups,but the ROM of dorsal extension (49.6° ± 4.1°),ROM of volar flexion (58.6°± 3.5°),ROM of supination (78.1° ± 7.5°),ROM of pronation (81.4°± 7.0°),GS (58.5％ ± 11.2％) and DASH scores (17.3 ± 7.9) in the emergency group were all significantly better than those in the selective group (37.0° ± 6.3°,45.1 ° ± 3.6°,70.7 ° ± 9.6°,67.1 ° ± 10.3°,37.3％ ±9.1％ and 32.5 ± 9.6,respectively) (all P ＜ 0.05).At 12 weeks after operation,the ROM of dorsal extension (64.8° ± 7.9°),ROM of volar flexion (70.5°± 9.7°),GS (80.4％ ± 9.9％) and DASH scores (7.7 ± 4.9) in the emergency group were significantly better than those in the selective group (41.2°± 7.0°,61.6°±10.9°,66.9％ ±18.2％ and 14.2±7.3,respectively) (P ＜0.05),but there were no significant differences between the 2 groups in ROM of supnition or pronation (P ＞ 0.05).At 48 weeks after operation,there were no significant differences between the 2 groups in ROMs,GS or DASH scores (P ＞ 0.05).Postoperatively,superficial infection happened in one case and the extensor pollicis longus muscle tendon was ruptured in another in the emergency group.Conclusion In the elderly women with dorsally displaced extra-articular fracture of the distal radius,emergency surgery with a volar locking plate may lead to better functional recovery within 12 weeks post-surgery than the elective or delayed surgery.

Effects of unilateral and bilateral diffusion of cement on osteoporotic vertebral compression fractures treated with percutaneous kyphoplasty / 中华创伤杂志

Objective To evaluate the effects of unilateral and bilateral diffusion of cement on osteoporotic vertebral compression fractures treated with percutaneous kyphoplasty (PKP). Methods A retrospective case control study was conducted on the clinical data of 127 patients with single segment osteoporosis vertebral compression fracture (OVCF) treated by unilateral puncture PKP between July 2013 and July 2015. According to whether the diffusion of bone cement crossed the median, all cases with OVCF were divided into unilateral and bilateral diffusion groups. The unilateral diffusion group (72 cases) included 29 males and 43 females, with an average age of 69.5 ± 2.6 years (range, 63-76 years). In terms of the injured segment, there were 38 cases of L1, 20 L2, 11 L3, two L4, and one L5. In the unilateral diffusion group, the preoperative visual analog score (VAS) was (7.8 ±0.9) points, the preoperative anterior vertebral height compression ratio was (32.5 ±6. 3)％, and the preoperative Cobb's angle of the injured vertebra was (9.2±1.3)°. The bilateral diffusion group (55 cases) included 22 males and 33 females, with an average age of 71.2 ±2.9 years (range, 61-80 years). In terms of the injured segment, there were 32 cases of L1, 13 L2, six L3, three L4, and one L5. In the bilateral diffusion group, the preoperative VAS was (7.6 ±0. 9)points, the preoperative anterior vertebral height compression ratio was (34.5 ±5.8)％, and the preoperative Cobb's angle of the injured vertebra (9.8± 1.5)°. The VAS, anterior vertebral height compression ratio of the injured vertebra, Cobb's angle of the injured vertebra, and injured and non-injured vertebra refracture 1 month and 1 year after operation were recorded. Results The patients were followed up for 12-16 months (mean, 14.6 ± 0.6 months) in unilateral diffusion group and for 13- 16 months (mean, 15.2 ±0.2 months) in bilateral diffusion group. The VAS score of the unilateral diffusion group was (3.0 ±0.4) points at 1 month after the operation and (2.2±0. 4) points at 1 year after the operation, respectively. The VAS score of the bilateral diffusion group was (2.1 ±0.4) points at 1 month after the operation and (1.5 ± 0.4) points at 1 year after the operation, respectively. The VAS score decreased significantly 1 year after operation compared with that before operation (P ＜0.05), and significant difference was noted between two groups (P ＜0.05). The anterior vertebral height compression ratio of the unilateral diffusion group was (15.2±3.9)％ at 1 month after the operation and (16.3 ±3.4)％ at 1 year after the operation, respectively. The anterior vertebral height compression ratio of the bilateral diffusion group was (15.6±3.5)％ at 1 month after the operation and (16.8 ±3.9)％ at 1 year after the operation, respectively. The Cobb's angle of the injured vertebra of the unilateral diffusion group was (2.9±0.7)° at 1 month after the operation and (3.0±0.6)°at 1 year after the operation, respectively. The Cobb's angle of the injured vertebra of the bilateral diffusion group was (3.0 ± 0.7) ° at 1 month after the operation and (3.2 ± 0.7) ° at 1 year after the operation, respectively. The anterior vertebral height compression ratio and Cobb's angle of the injured vertebra decreased significantly after surgery (P ＜ 0.05), but no statistically significant differences were observed between two groups (P＞0.05). The injured vertebra refracture ratio was 6.9％ in unilateral diffusion group and 0 in bilateral diffusion group. The non-injured vertebra refracture ratio was 5.6％ in unilateral diffusion group and 5.5％ in bilateral diffusion group. No nerve root injury, cerebrospinal fluid leakage, pulmonary embolism, anaphylactic shock and postoperative infection were found in the two groups. Paravertebral bone cement leakage occurred in two cases of the unilateral diffusion group and anterior vertebral bone cement leakage occurred in one case of the bilateral diffusion group. Conclusion Compared with unilateral diffusion, bilateral diffusion of bone cement has better analgesic effect and can reduce the incidence of re fracture of injured vertebra, without increasing the risk of re-fracture of the non-injured vertebrae.

They were diagnosed by semen analysis (including quantity of semen, pH and fructose), digital rectal examination, transrectal ultrasonography, magnetic resonance images and aspiration biopsy when necessary. All patients were treated by transurethral electrotomy combined with seminal vesiculoscopy ejaculatory duct dilatation and were followed up for 12 months. 
@*RESULTS@#A significant improvement of semen quality was achieved after surgery and the sperms could be seen. The patients' semen was analyzed for 3 times in 12 months and the results were normal. Semen volume and pure berries of the patients were increased after the operation compared with those before the operation (P<0.05). Spontaneous pregnancies were achieved in 3 patients 9-12 months after surgery. Four patients' seminal vesicle became smaller obviously.
@*CONCLUSION@#Transurethral electrotomy combined with seminal vesiculoscopy ejaculatory duct dilatation is effective and safe for the treatment of Müllerian duct cyst accompanied with ejaculatory duct obstruction.

Immediate Effects of Sustained Forced-blowing Exercise on Phonation Function in Healthy Youths / 中国康复理论与实践

@#Objective To observe the immediate effects of the sustained forced-blowing exercise (SFBE) on the phonation function in young healthy people. Methods 43 young healthy people were asked to pronounce a longest /a/ in a comfortable situation within one breath for 3 times before and after SFBE. The sound files were analyzed with computer sound analysis system, with the parameters of mean maximum phonation time (MMPT), mean frequency (MF) and mean sound pressure level (MSPL). Results The MMPT and MSPL increased (P< 0.01) after SFBE. There was no significant difference in the MF (P>0.05) before and after SFBE. Conclusion The SFBE can improve the MPT and MSPL of the healthy people obviously, without affections on the MF.

Analysis of effects of obesity on respiratory recovery after anesthesia / 中国基层医药

Objective To observe the respiratory system adverse drug reaction ( AREs) in obese patients in anesthesia recovery incidence and treatment outcome .Methods This was a control prospective trial .Study was con-ducted on 27 cases of obesity and the same amount of normal with body mass index (BMI)<30(control group).The sex distribution ,age and the type of operation and operation was similar between the two groups .The hospitalization rate of AREs in PACU was observed .Descriptive analysis on the variables ,use Mann-Whitney U,compared with chi square test and Fisher exact test of variables .The relationship between variables and AREs was studied by using uni-variate and multivariate Logistic retrospective analysis .Results Obese patients with the STOP-Bang≥3 ( 89% vs 11%,P<0.001)occur more frequently,obese patients had a lower rate of underwent high risk operations (7% vs 41%,P=0.005) and big operation (4% v s15%,P=0.008).Obesity in PACU patients were more susceptible to getting AREs(33% vs 7%,P<0.018).Multivariate analysis indicated that obesity and residual muscle relaxation effect was the independent risk factors of AREs .Obese patients in PACU had a longer periods of time treatment (120min vs 84min,P<0.001).Conclusion Obesity is an independent risk factor for PACU in patients with AREs . Obese patients in PACU were treated time more longer .

Mesocaval shunt plus portaazygous disconnection for portal hypertensive variceal bleeding caused by cavernous transformation of the portal vein in adults / 中华普通外科杂志

Objective To investigate the clinical effect of mesocaval shunt and selective coronary vein ligation for portal hypertension caused by cavernous transformation of the portal vein in adults.Methods The clinical data of 26 adult patients with portal hypertensive variceal bleeding caused by cavernous transformation of the portal vein treated by mesocaval shunt plus splenic artery and coronary vein ligation were analyzed retrospectively from 2001 to 2011.Results There was no operative deaths,free portal vein pressure decreased postoperatively,differences were significant before and after shunt (34.4 ± 4.7) cm H2O vs.(24.8 ±2.7) cm H2O,t =12.30,P ＜0.01.Postoperative complications included slight hepatic encephalopathy in 1 case,stress ulcer bleeding in 1 case,which were cured by conservative treatment.23 cases were followed up from 6 months to 4.5 years,and there was no bleeding case.Conclusious Mesocaval shunt plus selective vascular ligation for portal hypertensive variceal bleeding caused by cavernous transformation of the portal vein in adults is safe and effective.

Biotype common handle (short handle) prosthesis in treatment of femoral intertrochanteric fracture in the elderly / 中华创伤杂志

Objective To discuss and analyze effect of biotype common handle (short handle) prosthesis in treating aged patients with femoral intertrochanteric fracture.Methods A retrospective analysis was carried out on 321 patients,among which 280 (102 males and 178 females,at age of 72-98years,average 82.5 years) obtained follow-up.According to a new fracture classification method (Piansui Classification),the typeⅠ a fracture was found in 65 cases and type Ⅰ b in 215.Most patients were combined with medical diseases,and after related medical collaborative treatment,standard biotype common handle prosthesis (artificial bipolar femoral head) replacement was applied to all patients.Early rehabilitation exercise was performed postoperatively.Results All the 321 patients lived through perioperative period successively,with no death in hospitalization.Meanwhile,postoperative complications were all cured in hospitalization.The patients could take out-of-bed activity at 1-3 weeks after operation.All 280 patients could take care of themselves at 12-46 months (average 28 months) of follow-up.According to Harris score,the results were excellent in 129 cases,good in 121,fair in 22 and poor in eight,with excellence rate of 89.3％.Conclusion Biotype common handle artificial femoral head replacement is an effective method to allow early ambulation,reduce complications and improve quality of life in treatment of intertrochanteric fractures in the elderly.
