Objective To evaluate the prognosis of surgery in multilocular cystic renal cell carcinoma (MCRCC). Methods The characteristics of prognosis of surgery in 22 MCRCC cases out of 482 cases of renal cell carcinoma were reviewed.The MCRCC cases accounted for 4.56% of the renal cell carcinoma cases with a male-to-female ratio of 2.67∶1 in the same period.The mean age of the 22 patients was 47 years (age range,32-74 years). Results Of the 22 cases,18 underwent radical nephrectomy and 4 partial nephrectomy.The diameter of the tumors ranged 1.8-11.0 cm (mean 4.8 cm).Histological examination showed that 21 cases were of clear cell carcinoma and 1 of clear cell carcinoma mixed with granular cell carcinoma.Pathological staging showed pT 1N 0M 0 in 19 cases (86.4%),pT 2N 0M 0 in 2(9.1%) and pT 3bN 0M 0 in 1(4.5%).The classification by tumor nuclear grading system showed 5 cases (23%) of G 1 and 17 (77%) of G 2.Twenty patients were followed up for 9-56 months (mean,27.6 months) and 2 were lost of follow-up.Of the 20 patients,19 survived with no evidence of cancer and 1 died of intercurrent disease (upper gastrointestinal massive hemorrhage due to hepatocirrhosis). Conclusions MCRCC represents a distinct subtype of renal cell carcinoma.It is usually with low grade,low stage and is found incidentally.Our results indicate that MCRCC can be cured by surgery.Regardless of tumor size,the prognosis of MCRCC is favorable.

Objective To explore the effect of a multimodal electroencephalogram ( EEG) data visualiza-tion system on the motor imagery ability of stroke survivors. Methods Twenty stroke patients were randomly di-vided into an experimental group and a control group, each of 10. Both groups were provided with brain-computer interface-based motor imagery ( MI) training. At the same time, the experimental group was monitored and guided using an online, multimodal EEG data visualization system developed in our department. The classification accuracy ( CA) and event-related desynchronization ( ERD) of the 2 groups′ motor imagery were compared before and after the treatment. Results Before the treatment, no significant differences in the average CA of MI were found be-tween the experiment group (50.92±2.08) and the control group (49.35±4.20)(P>0.05). After the treatment, however, the experimental group′s average CA had increased to (64.52±5.27), significantly higher than that of the control group (51.18±5.02). When the stroke patients imaged affected upper extremity movements, obvious ERD was observed in the α frequency around the bilateral central motor regions of both groups, especially in the experi-mental group, but without significant differences between the two groups. However, no significant changes were found in the ERD of theβwaves of the two groups( P>0.05) . Conclusion The proposed online multimodal elec-troencephalogram data visualization system can help stroke patients imagine movements actively. It is worth sprea-ding in clinical practice.

BACKGROUND:Mirror therapy was initial y used in the treatment of affected limb pain after amputation, and has been applied as a valid way for relieving complex regional pain syndrome due to other injuries, but the efficacy for patients with upper limb complex regional pain syndrome (type II) more than 3 years after high-level spinal cord injury has not been reported in any way.
OBJECTIVE:To investigate the availability of mirror therapy for reducing pain in a patient with upper limb complex regional pain syndrome (type II) who suffered high-level spinal cord injury.
METHODS:An experimental design of self cross-control was applied for al eviating the patient’s pain with the intervention of transcutaneous electrical nerve stimulation and mirror box therapy, which were conducted 2 or 3 weeks respectively. And the elution period between two kinds of treatments was 1 week, the fol ow-up time was 1 month.
RESULTS AND CONCLUSION:The pain of the patient was not relieved, but even aggravated after 2 weeks of transcutaneous electrical nerve stimulation, while 3-week mirror box therapy significantly reduced the pain after elution period (the third week). The Hamilton anxiety scale, Hamilton depression scale, and WHO quality of life scale scores were significantly improved after treatment compared with before treatment. Experimental findings indicate that, mirror therapy may be an effective intervention for mitigating complex regional pain syndrome (type II) in addition to the comprehensive treatments, but further studies are warranted to confirm its effect.

Objective To explore the effects of transcutaneous electrical acupoint stimulation (TEAS) on paralytic hand and upper limb of stroke patients. Methods 32 patients were randomly divided into the treatment group (n=16) and the control group (n=16). All the patients accepted routine rehabilitation, and the patients in the treatment group accepted TEAS in addition for 6 weeks. They were assessed with Fug1-Meyer Assessment of upper extremities (FMA-UE), motor status scale (MSS) and Modified Barthel Index (MBI) before and 2, 4, 6 weeks after treatment. Results All the measures improved in both groups after 2, 4, and 6 weeks of treatment (P<0.05), while the scores of MBI improved more in the treatment group than in the control group 4 weeks after treatment (P<0.05), and all the measures improved more in treatment group than in the control group 6 weeks after treatment (P<0.05). Conclusion TEAS may promote the recovery of flaccid hand and upper extremity function post stroke.

Objective:To understand the current situation of care needs for disabled elderly people, analyze the impact of the family environment and community services on the care needs and care pathways of older people with disabilities and to formulate effective interventions.Methods:A cross-sectional survey was conducted from August 2022 to March 2023 in five tertiary-level hospitals in Tangshan city. The survey included 332 elderly people who were disabled before hospitalization and their primary caregivers, who were selected using a convenience sampling method. The survey investigated their general information, degree of disability, family members′ support, children′s filial piety and old age ethical level, family relationships, and the care needs of the elderly people who were disabled. SPSS 22.0 was used for one-way and correlation analyses as well as multiple linear regression analyses, and AMOS 22.0 was used for the development of structural equations for path analysis.Results:Among 332 disabled elderly individuals, there were 166 males and 166 females each. The care needs score for elderly people with disabilities was 101.54 ± 16.38. The care needs of this population can be influenced by several factors, including the level of disability, number of chronic conditions, presence of chronic pain, filial piety and old age ethical level of caregivers, family relationships, and the availability of care services in the community or village. These factors had direct effects of 0.468, 0.155, -0.083, -0.350, -0.094, and 0.104, respectively.Chronic diseases and chronic pain indirectly affected the demand for care through the degree of incapacity (with respective indirect effect values of 0.065 and 0.049). Additionally, the demand for care was indirectly influenced by the level of filial piety and ethics of the caregiver through the degree of incapacity and the family relationships (an indirect effect value of -0.162).Conclusions:The care needs of the disabled elderly are high, and the personal physiology, family environment and community support of the disabled elderly will directly or indirectly affect their care needs. Therefore, many factors should be considered comprehensively considered to improve the quality of care of the disabled elderly.

OBJECTIVETo observe the impacts of the intervention with electric thermalstone and air suction cup on blood perfusion (BP) at meridian points and explore the approach of accurate measurement and regulation of meridianand blood balance in "precise acupuncture".

METHODSThe laser Doppler line scanner (LDLS) was used to measure BP at bilateraln-primary points at the pericardium meridian, the triple energizer meridian, the gallbladder meridian and the liver meridian (small cycle oftomeridians) at 31 healthy receptors. The bias ratio of blood perfusion (BPBR) deviated to the reference value was calculated. The electric thermalstone and air suction cup were used in the intervention at the-sea points of the affected meridians in which BPBR was relatively higher at the-primary points. The electric thermalstone therapy was used when BPBR was less than -30% and the air suction cupping therapy was used when BPBR was higher than 30%. BP was measured twice before intervention and it was measured separately at the moment after intervention and in 20 min after intervention. The means of BP before and after intervention and the change ratio of blood perfusion (BPCR) before intervention, at the moment after intervention and 20 min after intervention were calculated.

RESULTS1. After the intervention of electric thermalstone, BP mean was increased from (103.51±41.21) PU to (121.97±56.22) PU (<0.05). Before intervention, at the moment after intervention and 20 min after intervention, separately, BRCR were (-0.58±16.18)%, (23.58±48.85) % and (25.62±65.89) %. BPCR at the moment after treatment was increased significantly as compared with that before intervention (<0.01). The difference was not significant in 20 min after intervention and before intervention (>0.05), but the change ratio was highly remained. 2. After intervention with air suction cup, BP mean was reduced from (194.83±81.14) PU to (173.88±88.26) PU. Before intervention, at the moment after intervention and 20 min after intervention, separately, BPCR were (7.62±30.49)%, (-12.12±18.20)% and (-14.35±21.25)%. BPCR at the moment after intervention and in 20 min after intervention were significantly different from that before intervention (both<0.01). .

CONCLUSIONThe electric thermalstone increases the blood flow at the-primary point when acting on the-sea point of the same meridian. The influence of the air suction cup is opposite.
