ABSTRACT
ObjectiveTo observe the architectural parameter changes of the muscles around the knee in middle-aged and elderly women with early knee osteoarthritis (KOA) by musculoskeletal ultrasound, and to clarify the indicators of muscles that affect early KOA. MethodsFrom January to August, 2022, 20 healthy middle-aged and elderly healthy women (controls) and 20 middle-aged and elderly women with unilateral early KOA (KOA group) were recruited through Beijing Bo'ai Hospital, to measure muscle thickness of the popliteus muscle, the muscle thickness and the pennation angle of the quadriceps, as rectus femoris, vastus intermedius, vastus lateralis, vastus medialis longus and vastus medialis oblique. ResultsCompared with the healthy limb of KOA group, and the controls, the muscle thickness of vastus medialis longus, vastus medialis oblique and popliteus muscle of the affected limb of KOA group became thinner (t > 2.133, P < 0.05); the proportion of thickness of vastus medialis oblique to thickness of vastus lateralis became smaller (t > 3.660, P < 0.05). The pennation angle was smaller in the affected limb of KOA group than in the matched dominant side of the controls (t = 3.101, P < 0.05). Logistic regression analysis showed that the muscle thickness of vastus medialis oblique (OR = 0.235, 95%CI 0.068 to 0.805, P = 0.021) and popliteus muscle (OR = 0.387, 95%CI 0.152 to 0.980, P = 0.045) were related to the onset of early KOA. ConclusionThe thickness of vastus medialis longus, vastus medialis oblique and popliteus muscle decrease, and the balance of the strength of vastus medialis oblique and vastus lateralis weakens in the affected limbs of the middle-aged and elderly women with early KOA. The thickness of vastus medialis oblique and popliteus muscle are protective factors for onset of KOA.
ABSTRACT
@#Objective To compare the pain relief and rehabilitation effect of intercostal nerve block and conventional postoperative analgesia in patients undergoing thoracoscopic surgery. Methods China National Repository, Wanfang Database, VIP, China Biomedical Literature Database, Web of Science, Clinicaltrials.gov, Cochrane Library, EMbase and PubMed were searched from establishment of each database to 10 Febraray, 2022. Relevant randomized controlled trials (RCTs) of intercostal nerve block in thoracoscopic surgery were collected, and meta-analysis was conducted after data extraction and quality evaluation of the studies meeting the inclusion criteria. Results A total of 21 RCTs and one semi-randomized study were identified, including 1 542 patients. Performance bias was the main bias risk. Intercostal nerve block had a significant effect on postoperative analgesia in patients undergoing thoracoscopic surgery. The visual analogue scale (VAS) score at 12 h after surgery (MD=–1.45, 95%CI –1.88 to –1.02, P<0.000 01), VAS score at 24 h after surgery (MD=–1.28, 95%CI –1.67 to –0.89, P<0.000 01), and VAS score at 48 h after surgery significantly decreased (MD=–0.90, 95%CI –1.22 to –0.58, P<0.000 01). In exercise or cough state, VAS score at 24 h after surgery (MD=–2.40, 95%CI –2.66 to –2.14, P<0.000 01) and at 48 h after surgery decreased significantly (MD=–1.89, 95%CI –2.09 to –1.69, P<0.000 01). In the intercostal nerve block group, the number of compression of the intravenous analgesic automatic pump on the second day after surgery significantly reduced (SMD=–0.78, 95%CI –1.29 to –0.27, P=0.003). In addition to the analgesic pump, the amount of additional opioids significantly reduced (SMD=–2.05, 95%CI –3.65 to –0.45, P=0.01). Postoperative patient-controlled intravenous analgesia was reduced (SMD=–3.23, 95%CI –6.44 to –0.01, P=0.05). Patient satisfaction was significantly improved (RR=1.31, 95%CI 1.17 to 1.46, P<0.01). Chest tube indwelling time was significantly shortened (SMD=–0.64, 95%CI –0.84 to –0.45, P<0.001). The incidence of analgesia-related adverse reactions was significantly reduced (RR=0.43, 95%CI 0.33 to 0.56, P<0.000 01). Postoperative complications were significantly reduced (RR=0.28, 95%CI 0.18 to 0.44, P<0.000 01). Two studies showed that the length of hospital stay was significantly shortened in the intercostal nerve block group, which was statistically different (P≤0.05), and there was no statistical difference in one report. Conclusion The relief of acute postoperative pain and pain in the movement state is more prominent after intercostal nerve block. Intercostal nerve block is relatively safe and conforms to the concept of enhanced recovery after surgery, which can be extensively utilized in clinical practice.
ABSTRACT
Objective:To investigate the correlation between RNF213 gene p. R4810K polymorphism and posterior cerebral artery involvement in Chinese children with familial moyamoya disease.Methods:Children with familial moyamoya disease admitted to the Department of Neurosurgery, the Fifth Medical Center of PLA General Hospital from August 2004 to June 2018 were enrolled, and they were divided into posterior cerebral artery involved group and posterior cerebral artery uninvolved group. RNF213 gene p. R4810K single nucleotide polymorphism was detected. Multivariate logistic regression analysis was used to determine the independent risk factors for posterior cerebral artery involvement. Results:A total of 65 children with familial moyamoya disease were enrolled. Their age was 6.98±4.46 years and 37 (56.9%) were male. The first symptom of 55 children (84.6%) was cerebral ischemia, and 37 (56.9%) involved posterior cerebral artery. There were 3 (4.6%) children with p. R4810K AA genotype, 26 (40.0%) with GA genotype, and 36 (55.4%) with GG genotype. The p. R4810K genotype distribution in the posterior cerebral artery involved group was statistically different from that in the uninvolved group (GA+ AA genotype: 56.8% vs. 28.6%; χ2=5.124, P=0.024), and there were no statistical difference in gender, age, first symptom, and genetic pattern. Multivariate logistic regression analysis showed that after adjusting the first onset age and gender, p. R4810K G>A mutation was the only independent risk factor for posterior cerebral artery involvement (odds ratio 3.240, 95% confidence interval 1.082-9.705; P=0.020). Conclusion:The p. R4810K polymorphism of RNF213 gene is associated with posterior cerebral artery involvement in Chinese children with familial moyamoya disease.
ABSTRACT
Objective:To summarize the patient profiles and therapeutic efficacies of ABO-incompatible living-related kidney transplantations at 19 domestic transplant centers and provide rationales for clinical application of ABOi-KT.Methods:Clinical cases of ABO-incompatible/compatible kidney transplantation (ABOi-KT/ABOc-KT) from December 2006 to December 2009 were collected. Then, statistical analyses were conducted from the aspects of tissue matching, perioperative managements, complications and survival rates of renal allograft or recipients.Results:Clinical data of 342 ABOi-KT and 779 ABOc-KT indicated that (1) no inter-group differences existed in age, body mass index (BMI), donor-recipient relationship or waiting time of pre-operative dialysis; (2) ABO blood type: blood type O recipients had the longest waiting list and transplantations from blood type A to blood type O accounted for the largest proportion; (3) HLA matching: no statistical significance existed in mismatch rate or positive rate of PRA I/II between two types of surgery; (4) CD20 should be properly used on the basis of different phrases; (5) hemorrhage was a common complication during an early postoperative period and microthrombosis appeared later; (6) no difference existed in postoperative incidence of complications or survival rate of renal allograft and recipients at 1/3/5/10 years between ABOi-KT and ABOc-KT. The acute rejection rate and serum creatinine levels of ABOi-KT recipients were comparable to those of ABOc-KT recipients within 1 year.Conclusions:ABOi-KT is both safe and effective so that it may be applied at all transplant centers as needed.
ABSTRACT

Even after reparing enteric fistula , the risk of leakage remains high . Roux-en-Y anastomosis is other therapeutic option .
ABSTRACT
Objective To study the role of interictal epileptiform discharge (IED) in reducing recurrent epilepsy after withdrawal of antiepileptic drugs (AED).Methods One hundred epilepsy pa tients with no seizure for ≥2 years were divided into IED group (n=51) and IED free group (n=49) according to the classification of epilepsy seizure developed by the International Association for the Prevention of Epilepsy in 1981.The patients were further divided into elderly group (n=21) and non-elderly group (n=79) and were followed up for at least 1 year by return visit or telephone.Results No significant difference was found in the incidence of IED in the 100 epilepsy patients with different types of seizure,such as myospasm,simple partial seizure and ≥2 seizures.However,the incidence of IED was significantly higher than that of myotonia,myospasm,absence and simple partial seizure (P＜0.05).Epilepsy recurred in 37 patients (72.5％) of IED group and in 16 patients (32.7％) of IED-free group.Logistic regression analysis showed that the course of epilepsy and IED were the risk factors for recurrent epilepsy after withdrawal of AED (OR=1.165,95％CI:1.022-1.329,P=0.022;OR=2.794,95％CI:1.040-7.509,P=0.042) and the course of epilepsy was longer in elderly group than in non-elderly group (10.10±7.55 years vs 5.97±4.04 years,P=0.001).Conclusion The seizure type and course of epilepsy are the relia ble predictors of recurrent epilepsy in patients with no seizure for a long time after withdrawal of AED,and are thus of clinical significance.
ABSTRACT
Objective To preliminarily explore the clinical features,treatment,and outcomes of moyamoya disease in the elderly.Methods The clinical data of the elderly patients with moyamoya disease (aged ＞ 60 years) admitted to the Department of Neurosurgery,the 307th Hospital of PLA from May 2007 to July 2016 were collected retrospectively.Their clinical features,imaging features,and surgical outcomes were analyzed.Results A total of 68 patients were enrolled,including 35 females (51.47％) and 33 males (48.53％).The ratio of male to female was 1:1.06.The age at the time of diagnosis of moyamoya disease was 62.82 ±3.08 years.Fifty-two patients (76.5％) had vascular risk factors.The most common clinical manifestation was cerebral ischemia (n =61,89.7％).Thirty of them (44.1％) presented as transient ischemic attack.The Suzuki staging of most patients was 4-6 (71.6％),12 patients (17.6％) complicated with posterior cerebral artery stenosis or occlusion.Thirty-one patients were treated with encephalo-duroarterio-synangiosis (EDAS).Among them,17 patients underwent bilateral surgery and 14 underwent unilateral surgery.The incidence of perioperative infarction or hemorrhage was 5.6％ (2 patients developed cerebral infarction and 1 patient developed cerebral hemorrhage);37 patients received conservative treatment.During the follow-up period,5 patients developed cerebral infarction (1 in the surgical treatment group and 4 in the conservative treatment group);there was no significant difference between the 2 groups.There were no significant differences in age,sex,vascular risk factor,clinical symptoms,and preoperative modified Rankin Scale (mRS) scores between the 2 groups.Cerebral angiography was performed 6-9 months after operation in the surgical treatment group.A total of 24 cerebral hemispheres were evaluated by Matsushima typing,of which 17 (70.8％) were excellent.During the follow-up period,the proportion of patients with clinical outcome excellent (the mRS score was 0) (Z =-5.268,P ＜ 0.00l) and clinical improvement (the mRS score was improved ≥ 1 compared to the baseline) (Z =-3.780,P ＜ 0.001) were significantly higher than the conservative treatment group.Conclusions The clinical symptoms of old patients with moyamoya disease were mainly cerebral ischemia.Most of them had vascular risk factors,and the imaging manifestations showed higher Suzuki staging.The perioperative risk of EDAS in the old patients with moyamoya disease was lower.It might be an effective method to prevent clinical symptoms progress and improve the outcomes.
ABSTRACT
BACKGROUND:Comparative study results between the efficacies of traditional Chinese medicine (TCM) therapy with Western medicine therapy in the treatment of knee osteoarthritis remain controversial. Currently, meta-analysis studies mainly focuson comparison of the efficacy between TCM and Western medicine,butlack investigations among TCM therapies. Itmakes usdifficult tofulyunderstand the efficacy of TCM therapy for knee osteoarthritis. OBJECTIVE:To compare the efficacies of TCM therapy with intra-articular injection of hyaluronic acid for knee osteoarthritis using a networkMeta-analysis method. METHODS:PubMed, The Cochrane Library (tissue 10, 2015), EMbase, CNKI, CBM, VIP, Wangfang databaseswere searchedup to October 20, 2015forrelevantrandomized controled trialsaddressingthe efficacies of TCM therapyversusintra-articular injection of hyaluronic acid for knee osteoarthritis. Two reviewers independently selected the studies, extracted information, and assessed the quality of included trials. Data extraction from eligible studies was pooled and meta-analyzed using Stata12.0 and WinBUGS1.4.3softwares. Odd ratios with their 95% confidence interval were estimated as effect size between treatments. RESULTS AND CONCLUSION:A total of 59 randomized controled trials involving 6 155 patients with knee osteoarthritis and 12 treatment strategies were included. The results of network meta-analysis showed that TCM comprehensive therapy wassuperior to the TCM monotherapy and intra-articular injection of hyaluronic acid. Among thesetherapies, the efficacy of needle scalpel combined with acupuncture is optimal. TCM comprehensive therapies may be the best choice to treat patients with knee osteoarthritisofKelgren-LawrenceII-III. Morelarge-scaleand wel-designedrandomized controled trials are stil warranted due to the limitation of the present study.

Compared w ith the patients w ith moyamoya disease at the same period, the proportion of patients w ith cerebral infarction as initial symptom w as higher in the moyamoya syndrome group ( 39.0% vs.24.2%; χ2 = 4.796, P =0.029), more patients had symptomatic progression (46.3% vs.25.4%; χ2 =9.207, P =0.002), and the proportion of of patients w ith cerebral hemorrhage as initial symptom w as low er ( 2.4% vs.14.6%; χ2 = 4.829, P =0.028). Thirty-seven patients w ho received encephalo -duro-arterio-synangiosis (EDAS) w ere folow ed up for 43 ± 19 months. The results show ed that the clinical symptoms of 31 patients had different degrees of improvement. Conclusions Moyamoya syndrome of hyperthyroidism is more common in w omen. The risk of cerebral infarction is higher and more prone to have disease progression. The efficacy of EDAS is better for controling the progression of moyamoya syndrome in patients w ith hyperthyroidism.
ABSTRACT
Objective To summarize the diagnosis and treatment experience of mucor infection in renal grafts.Methods Clinical data of two patients with mucor infection in renal grafts from the same kidney donor that finally caused renal graft and renal artery rupture were retrospectively studied,and the relevant domestic and foreign literatures were reviewed. Results and conclusions Mucor infection after renal transplantation has no specific manifestation,thus it lacks of means of early diagnosis and is easy to cause misdiagnosis and missed diagnosis.Mucor infection is easy to cause vascular rupture and the prognosis is poor.Early diagnosis, thorough debridement, timely selection of effective antifungal agent, withdrawal of immunosuppressant and correction of coagulation disorders under the monitor of thrombelastogram may improve the survival rate of such patients.
ABSTRACT
Objective To investigate the clinical features of subarachnoid hemorrhagic moyamoya disease and the therapeutic effect of encephalo-duro-arterio-synangiosis (EDAS). Methods The clinical and imaging data of 38 patients with subarachnoid hemorrhagic moyamoya disease admitted to the Department of Neurosurgery,the 307th Hospital of PLA from January 2002 to April 2013 were analyzed retrospectively. Thirty-five patients underwent unilateral or bilateral EDAS (64-sides underwent EDAS,4 patients with aneurysms underwent endovascular embolization first),and 3 patients did not undergo any surgery. Results (1)Subarachnoid hemorrhagic moyamoya disease accounted for 10. 8%(38/353)of all the hemorrhagic moyamoya disease admitted in hospital over the same period,including 37 adults and 1 child. The male to female ratio was 1∶3. 22 (9/29),and the age of onset was 12 to 59 years. The mean age of patients was 39 ± 11 years. Four patients were combined with aneurysms. There were no significant differences in the distribution of Suzuki stage,anterior choroidal artery dilatation and posterior communicating artery dilatation in the remaining 34 patients without aneurysms between the bleeding sides and non-bleeding sides (P>0.05). (2 ) The patients were followed up for 13 -125 months (mean 51 ± 27 months ),two patients had rebleeding,one of them was intraventricular hemorrhage,the other was parenchymal hemorrhage. The postoperative modified Rankin score (mRS)was significantly lower in 35 patients whom were treated with EDAS. Compared with before surgery,there was significant difference (P<0. 05). The re-examination of positron emission tomography (PET)for 16 patients at 3 to 19 months after surgery showed that among the 23 surgically treated hemispheres,the cerebral metabolisms of 17 hemispheres were improved after surgery, and 6 did not have any change after surgery. The re-examination of whole brain digital subtraction angiography (DSA)at 5 to 30 months after surgery in 13 patients showed that revascularizations in 19 of 23 surgical hemispheres were effective. Conclusion Subarachnoid hemorrhagic moyamoya disease often occurs in adults,and women are more common. EDAS can achieve good revascularization effect and improve brain metabolism of patients,and thus relieve the symptoms of cerebral ischemia.
ABSTRACT
To study the expression and distribution of neuropeptide Y (NPY) and long leptin receptor (OB-Rb) in the gastrointestinal tract of giant panda, samples of three animals were collected from the key laboratory for reproduction and conservation genetics of endangered wildlife of Sichuan province, China conservation and research center for the giant panda. Paraffin sections of giant panda gastrointestinal tissue samples were observed using hematoxylin-eosin staining (HE) and strept actividin-biotin complex immunohistochemical staining (IHC). The results show that the intestinal histology of three pandas was normal and no pathological changes, and there were rich single-cell and multi-cell mucous glands, long intestinal villi and thick muscularis mucosa and muscle layer. Positive cells expressing NPY and OB-Rb were widely detected in the gastrointestinal tract by IHC methods. NPY positive nerve fibers and neuronal cell were widely distributed in submucosal plexus and myenteric plexus, especially in the former. They were arranged beaded or point-like shape. NPY positive cells were observed in the shape of ellipse and polygon and mainly located in the mucous layer and intestinal glands. OB-Rb positive cells were mainly distributed in the mucous layer and the laminae propria, especially the latter. These results confirmed that NPY and OB-Rb are widely distributed in the gut of the giant panda, which provide strong reference for the research between growth and development, digestion and absorption, and immune function.

Objective To investigate the effect of free toe transplantation in finger reconstruction.Methods Free toe transplantations were performed in 164 patients (185 fingers) suffering from finger defection.There were 134 males and 30 females,aged at 12-83 years [mean (44.8 ± 11.2)years].Finger deletion severity was classified as grade Ⅰ in one case,grade Ⅱ in 18,grade Ⅲ in 23,grade Ⅳ in 49,grade Ⅴ in 54,and grade Ⅵ in 19.According to Gilbert standards,dorsal metatarsal arteries were classified as type Ⅰ in 68 cases,type Ⅱ in 84,and type Ⅲ in 12.Survival ratio of the transplanted fingers and hand function rehabilitation were observed.Results The transplanted toe survived in 160 cases (173 fingers).They composed of all the cases of grade Ⅰ-Ⅴ finger deletion and 15 cases of grade Ⅵ finger deletion; all the cases of type Ⅰ dorsal metatarsal arteries,83 cases of type Ⅱ dorsal metatarsal arteries and nine case of type Ⅲ dorsal metatarsal arteries.Transplantation failed in four cases (12 fingers) of grade Ⅵ finger defection including one case of Gilbert Ⅱ dorsal metatarsal arteries and three cases of Gilbert Ⅱ dorsal metatarsal arteries.Postoperative results were excellent in 110 cases and good in 50.Conclusions Toe transplantation is helpful to restore the finger shape and function and the outcome is satisfactory.Anatomic deformation of dorsal metatarsal arteries is the main cause for the failure of finger reconstruction.
ABSTRACT
Objective To explore differential expression of protiens between patients with esophageal cancer and healthy individuals, and to screen out the tumor biomarkers to construct a dignostic model. Methods From January to August, 2008, the clinical data of 127 patients with esophageal cancer (esophageal cancer group) who had been admitted to the First Affiliated Hospital of Xinjiang Medical University and 63 healthy individuals (control group) were retrospectively analyzed. The serum proteomic profiles of the esophageal cancer pateints and healthy individuals were deteced by weak cation exchange and hydrophobic surface ProteinChip using the surface enhanced laser desorption/ionization-time of flight-mass spectrometry (SELDT-TOF-MS) technique.Serum differentially expressed markers of esophageal cancer were screened out to establish the diagnostic model for esophageal cancer. All data were analyzed using rank sum test. Results Six proteins were high-expressed in the esophageal cancer group, and the mass-to-charge ratios were 4488, 5495, 15964, 3948, 8154, 8166. Four were low-expressed in esophageal cancer group, and the mass-to-charge ratios were 8789, 6682, 8714, 6650. A diagnostic model consisting six proteins was established. A total of 124 patients were correctly diagnosed and three were misdiagnosed in the esophageal cancer group, and 60 were correctly diagnosed and three were misdiagnosed in the control group. The accuracy, sensitivity and specificity of the diagnostic model were 96.8% ( 184/190),97.6% ( 124/127 ) and 95.2% (60/63). Conclusions The diagnostic model established based on the tumor markers screened out by the SELDT-TOF-MS is highly sensitive and specific.
