Objective To investigate the safety and feasibility of carotid endarterectomy (CEA) combined with carotid artery stent angioplasty (CASA) in treating tandem stenosis of carotid artery. Methods The clinical data of 9 patients with tandem stenosis of carotid artery, who were treated at authors' hospital during the period from January 2013 to October 2014, were retrospectively analyzed. The patients included 7 males and 2 females, with a mean age of (66.0 ±4.2) years. The disease course ranged from 2 months to 36 months, with a mean of 7 months. Clinically, all patients had cerebral ischemia symptoms. Transient ischemia attack was seen in 5 patients and history of cerebral infarction was present in 2 patients. Coronary artery disease was found in 2 patients, hypertension in 6 patients and lower limb ischemia in one patient. After receiving adequate antiplatelet therapy, CEA and CASA were carried out in all patients. Results The technical success rate was 100%, postoperative residual stenosis was less than 30%, no death occurred in perioperative period. After the treatment, the clinical symptoms were improved in all 9 patients;no new stroke or cerebral hemorrhage occurred. After the treatment, 2 patients developed cerebral hyperperfusion-related symptoms such as headache and dizziness, which were much relieved at the time of discharge. The patients were followed up for 4-19 months, with a mean of (10.5±6.2) months. No recurrence of symptoms was observed . In one patient , transcranial Doppler ultrasound performed at 6 months after treatment showed that the carotid artery became moderate restenosis (50%-70%). No death occurred. Conclusion For the treatment of tandem stenosis of carotid artery, CEA combined with CASA is safe and effective, although larger sample and long-term follow-up studies are still needed to further confirm the effect.

Objective To discuss the methods, advantages and indications of multipoint puncturing in performing endovascular therapy for complex lower extremity arterial occlusive diseases. Methods During the period from Oct. 2011 to Oct. 2013, a total of 46 patients with complex lower extremity arterial occlusive diseases were treated with endovascular therapy by using multipoint puncturing technique. The puncturing type, the advantages of multipoint puncturing technique and the success rate of this technique were analyzed. Results The multipoint puncturing was divided into three types: type Ⅰ : puncturing from the opposite direction to deal with the same target vessel; type Ⅱ: direct puncturing of the target vessel; and type Ⅲ:using the same puncturing direction to deal with different target vessels. The success rate of endovascular treatment was 80.4%. Conclusion Multipoint puncturing technique helps improve endovascular treatment success rate for lower extremity arterial occlusive diseases. Full understanding of the advantages of multipoint puncturing technique, perfect preoperative planning, precise puncturing technique and proper interventional equipments are helpful to ensure a successful treatment.

Increasing age is the most important factor for cognitive impairment.Alzheimer disease(AD)and sarcopenia are significant causes of frailty and disability in older adults.It is important to have an in-depth understanding of the relationship between sarcopenia and AD.Studies have reported that sarcopenia often disturbs the secretion of muscle factors,which may increase the risk of developing dementia.In turn,the pathological feature of dementia,such as the de-position of amyloid β-protein(Aβ),amyloid precursor protein(APP)and tau protein in peripheral neurons,may be related to a decline in muscle function.In particular,the deposition of Aβ and APP may eventually lead to movement disorders and disability.Therefore,we hypothesize that AD and sarcopenia may mutually promote each other's pathological develop-ment.This results in exacerbation of clinical and pathological damage,in which myokine and amyloid proteins play impor-tant roles.However,the interrelationship based on amyloid protein and myokine production has not been discussed in de-tail in other reviews.In this paper,we reference and discuss the studies on this topic,and review the common risk factors for sarcopenia and AD and the potential and mechanisms for mutual improvement.

Objective:To assess the clinical result of repeated combined detrusor-trigone botulinum toxin A(BTX-A)injection and intermittent catheterization(IC) for male adults with neurogenic detrusor overactivity (NDO) and urinary incontinence(UI) secondary to spinal cord injury(SCI).Methods:From January to August 2021, the data of 43 adult male patients with NDO and UI secondary to SCI who received repeated trigone-including intradetrusor BTX-A injection in Guangdong Provincial Work Injury Rehabilitation Hospital were retrospectively analyzed. The mean age of the patients was (29.1±10.7) years. The mean incontinence specific quality of life (I-QOL) was (39±4.8). The UI episodes was (11.9±2.6), mean voiding volume was (170.7±20.1)ml, mean maximum detrusor pressure at first NDO was (81.4±19.6) cmH 2O and mean volume at first NDO was (169.1±40.0)ml.All patients received trigone-including intradetrusor BTX-A (300 U, 30 sites) injection for four times and IC. Clinical data including I-QOL, bladder diary, video-urodynamic test and adverse events were recorded at baseline and 12 weeks after each injection. Results:Mean interval between four injections were (220.6±27.4), (222.8±24.1) and (224.4±39.0) d ( P=0.13). Compared with baseline data before first injection, mean I-QOL after the first, second, third and fourth injection increased to (54.9±9.1), (56.1±7.9), (61.7±9.1) and (68.8±8.9) (all P<0.001). The number of urinary incontinence cases decreased to 36, 35, 35 and 33 (all P<0.05). The mean urinary incontinence episodes per day decreased to (4.4±0.6), (3.8±0.4), (2.2±0.5) and (2.1±0.3)(all P<0.001). Mean voiding volume increased to (288.3±40.2), (300.0±38.6), (316.9±46.8) and (319.5±36.7) ml (all P<0.001). Mean maximum detrusor pressure at first NDO decreased to (29.4± 11.0), (26.1±8.7), (20.3±5.9) and (18.5±6.0) cmH 2O (all P<0.001) and mean volume at first NDO increased to (270.0±48.7), (284.9±51.3), (287.7±47.9) and (303.0±46.2) ml (all P<0.001), respectively. Compared with four injections, no difference in response was found in the mean I-QOL, the number of urinary incontinence cases, mean urinary incontinence episodes mean voiding volume, mean maximum detrusor pressure at first NDO and mean volume at first NDO (all P>0.05). No de novo VUR occurred and 2 cases of grade Ⅱ VUR at baseline had resolved after the first injection. 9 patients experienced serious gross hematuria within first week after injection, but the urine returned to clear by prolonging the catheter indwelling time or bladder irrigation. 12 patients with active urinary tract infection were treated with indwelling catheter and sensitive antibiotics. Patients continued IC when the symptoms, signs and laboratory examination were normal. Conclusions:Combined detrusor-trigone BTX-A injection and IC could help decrease detrusor pressure, restore some of the lower urinary tract function and improve the quality of life for male patients with NDO and UI secondary to SCI. Repeated injection is as effective and safe as the first injection.

Schizophrenia is a serious mental disease. The diagnosis of schizophrenia so far relies heavily on subjective evidence, including self-reported experiences by patients, manifestations described by relatives, and abnormal behaviors assessed by psychiatrists. The diagnosis, monitoring of the disease progression and therapy efficacy assessment are challenging due to the lack of established laboratory biomarkers. Based on the current literature, clinical consensus, guidelines, and expert recommendations, this review highlighted evidence-based potential laboratory biomarkers for the diagnosis of schizophrenia, including genetic biomarkers, neurotransmitters, neurodevelopmental-related proteins, and intestinal flora, and discussed the potential future directions for the application of these biomarkers in this field, aiming to provide an objective basis for the use of these biomarkers in the early and accurate diagnosis, treatment, and prognosis and rehabilitation assessment of schizophrenia.

The penetrating moxibustion technique is proposed based on experience of the ancients and clinical practice for many years. From the aspects of definition, action characteristics and technique at different parts, the advantage and application experience of penetrating moxibustion have been discussed. The adequate dose of moxibustion is necessary in penetrating moxibustion; in addition, moxibustion sensation should be penetrating; therefore, with a temperature of 43℃ for more than 20 min, sweating, flushing, speckle appearing after penetrating moxibustion. Due to individual differences of age, gender and constitution factors, the effects of penetrating moxibustion are different, in clinical practice the body reaction and patient's feelings should be deliberately focused on other than does or sore and blister of moxibustion. The technique is common used in the abdomen, waist and knee joint, etc.
