Ultrasound brain perfusion imaging can evaluate brain perfusion in normal and pathological conditions. After basilar stent implantation, contrast-enhanced ultrasound (CEUS) can show normal visualization of color flow within the stent and provide essential functional information by evaluation of blood flow velocities. Furthermore, CEUS can estimate the volume of brain hemorrhage and readily identify residual tumor. CEUS can be used in thrombolysis, and will be applied in cerebral trauma. The value of CEUS in brain perfusion imaging was reviewed in this article.

AIM: To observe the realgar induced the apoptosis of eosinophils from bronchoalveolar lavage fluid in asthmatic guinea pigs and investigate the mechanism that realgar treated asthma.METHODS: The morphology of apoptosis of eosinophils was observed by Giemsa staining and electron microscope.The rate of apoptosis of eosinophils was assayed by the flow cytometry.RESULTS: The characteristic changes of the apoptosis in both light microscope and electron microscope were shown after 6 hours treatment of realgar.Flow cytometry showed that the rate of apoptosis of the eosinophils was increased with both increasing realgar concentration and prolonging realgar action time to the cells.CONCLUSION: Realgar promotes the apoptosis of eosinophils from bronchoalveolar lavage fluid in asthmatic guinea pig.Realgar induced the apoptosis of eosinophils is one of the causeses for asthmatic treatment.

Objective To analyze the cause of acute brain swelling,brain encephalocele in brain traumatic injury craniotomy,and the reason,diagnosis and treatment methods of progressive epidural hematoma.Methods The clinical data of 381 patients with brain traumatic injury craniotomy were retrospetively analyzed.Of 318 patients,27cases had progressive epidural hematoma during operation.Results 9 cases died because of functional failure of brain stem,the other 18 cases were all clinically cured.Conclusion If acute brain swelling and encephalocele occured during operation,the cause should be found quickly,especially when there was skull fracture or epidural hematoma on the contralateral brain,the head CT and operation should be taken immediately,and the bulging brain tissue should not be removed blindly,and the skull should not be forced to close,otherwise the prognosis maybe poor.

Objective To explore the value of the located needles guided by intraoperative ultrasound in resection of brain cavernous malformations. Methods Fourteen patients diagnosed as brain cavernous malformations confirmed by preoperative CT and MRI. Detected by the located needles under intraoperative ultrasound guidance, 14 lesions were excised. Results Intraoperative ultrasound-guided needles accurately located 14 cases of patients with brain cavernous malformations. Fourteen lesions were removed successfully. The distances between lesions and the dura mater were 1.5-2.9 cm,the sizes of lesions were 0.8-2.8 cm. Fourteen lesions by color Doppler flow imaging showed point-like blood flow. Conclusions Brain cavernous malformations can be accurately detected by the located needles under intraoperative ultrasound guidance.

Objective To explore the value of contrast-enhanced ultrasonography(CEUS) in brain injuries. Methods ① Models of graded brain trauma were created in brains of 10 healthy mongrel dogs after the animals were anesthetized and the cranium were removed. Conventional ultrasonography(US) and CEUS were performed to observe the characteristics of traumatic region. ② Thirteen patients with traumatic brain injuries were collected to perform intraoperative ultrasonography. The location, depth, size, internal echo and boundary of traumatic brain injuries were clearly displayed. Eight injury sites were chosen to undergo CEUS. Results ① Twelve injury sites in brains of 10 dogs were detected,and CEUS were peformed in 10 lessions, of which 1 was diagnosed with cerebral contusion, 1 with cerebral contusion and cerebral hemorrhage, 7 with intracerebral hematoma, 2 with ventricular hematoma, 1 with blood vessels in intracerebral hematoma. ② Fifteen lesions were detected by preoperative CT scan, but 18 lessions were detected by intraoperative ultrasound. During operation epidural hematomas in 4 cases were detected. After CEUS,the area of lessions was clearly revealed to be extended, the hemorrhage area was exempt from enhancement while peripheral normal cerebral tissue was homogenously enhanced. Conclusions Conventional ultrasonography could display brain injuries. In case of accurate intraoperative encephalocele, intraoperative untrasound conduces to discover delayed intracranial hematoma. Different traumatic brain injuries had their special CEUS findings.

Objective:To systematically evaluate the qualitative research on the practical experience of hospice care among medical staff in nursing homes, and to provide a reference basis for the implementation of hospice care services in nursing homes.Methods:The qualitative research on the practical experience of hospice care among medical staff in nursing homes was searched from databases including the Web of Science, PubMed, Cochrane Library, Embase, CINAHL, China National Knowledge Infrastructure, China Biology Medicine disc, Wanfang Data and VIP Database. The retrieval period was from the establishment of the database to March 21, 2024. The quality evaluation standards for qualitative research of the Australian Joanna Briggs Institute Evidence-Based Health Care Center were used to evaluate the quality of the literature. The results were integrated by the method of aggregative integration.Results:A total of 15 studies were included, and 47 clear research results were extracted, summarized into 11 categories, and 4 integrated results were obtained: the palliative care work responsibilities of medical staff; the emotional experience of medical staff in practice; coping with negative experience and gaining personal growth;the practical dilemmas faced by nursing homes when implementing hospice care.Conclusions:Nursing homes face multiple obstacles and challenges in the process of providing hospice care services. It is recommended that future research should focus on improving the policy system of hospice care in nursing homes, building a support system for hospice care services, and promoting the development and practice of death literacy among the public, so as to promote the healthy and long-term development of hospice care services in nursing homes.

This article introduced Professor Wang Xingkuan's academic thoughts and clinical experience in diagnosing and treating burning mouth syndrome(BMS)in perimenopausal women based on the theory of"yin injury and internal dryness".Professor Wang advocates the principle of"treating the root cause of the disease and harmonizing multiple organs".Starting from the unique physiological characteristics of perimenopausal women,he believes that the BMS in perimenopausal women should be attributed to the kidneys,liver,heart,and small intestine.The fundamental cause of the disease is the deficiency of kidney essence and the gradual decline of liver blood,and the key to the onset is the dryness of the kidney,liver,heart,and small intestine.In treatment,the overall strategy is to take"yin injury and internal dryness"as the main guideline,focusing on the liver and kidney,with nourishing and replenishing the liver and kidney as the main approach and clearing heat and moistening as auxiliary methods.The basic formula for treating BMS is a combination of Erdong Decoction and Baihe Dihuang Decoction,which has shown significant clinical efficacy.

Objective To observe the reliving of the work stress in new nurses by emotion management training. Methods A questionnaire about work stress was conducted among 60 nurses working in a level three class A hospital. The questionnaires included stress source questionnaire, the positive and negative emotion scale, trait coping style questionnaire and so on. After survey, 10 classes emotion management training was conducted. Then after training, the other survey result was collected and the data were analyzed. Results The work stress of new nurses were mainly caused by nursing specialty and work issues, especially frequent shift work. The score of positive emotion and coping were apparently increased, while the score of negative emotion and coping were decreased after training with statistical significance compared with scores before training ( P<0. 05). Conclusions The emotion management training was helpful to improve the positive emotion management and trait coping style, so as to relieve their work stress.

Objective To determine the influence of abiraterone acetate (AA) on neuroendocrine differentiation (NED) in metastatic castration-resistant prostate cancer (mCRPC) and the prognostic predicting value of the serum NED markers in mCRPC patients treated with AA.Methods We conducted an analysis in 115 chemotherapy-naive mCRPC patients who were treated with chemotherapy in Renji hospital from 2013 to 2017.The median age was 70,ranged from 65 to 76 years old.The median CgA,NSE and PSA levels were 101.1 ng/ml (78.5-150.0 ng/ml),13.4 ng/ml (10.5-17.6 ng/ml) and 38.8 ng/ml (11.2-123.2 ng/ml),respectively.Among them,48 cases were classified as the group without AA treatment.The other 67 cases were classified as group after AA failure.In group without AA treatment,the median CgA,NSE and PSA levels were 109.1 ng/ml(80-151.5 ng/ml);13.8 ng/ml(10.8-18.2 ng/ml) and 39.2 ng/ml (8.6-200 ng/ml),respectively.In group after AA failure,the median CgA,NSE and PSA levels were 105.4 ng/ml(78.8-175.5 ng/ml),13.8 ng/ml(10.8-17.6 ng/ml) and 39.0 ng/ml(8.4-219.8 ng/ml),respectively.In the group with serial evaluation of NED markers during AA treatment,the median serum CgA,NSE levels at baseline were 115.9 ng/ml(90.1-201.5 ng/ml),13.3 ng/ml (10.4-18.1 ng/ml),respectively.The endpoints were PSA PFS(progression-free survival) and radiographic PFS (rPFS).Results In 34 patients with serial evaluation,serum NED markers level in 19 patients increased after the failure of AA treatment.Median serum CgA and NSE levels were 115.9 ng/ml(90.1-201.5 ng/ml)and 13.25 ng/ml (10.37-18.14 ng/ml) at baseline.Median serum CgA and NSE levels were 129.6ng/ml (75.5-230.5 ng/ml) and 14.7 ng/ml (11.8-19.1 ng/ml) after 6 months treatment,respectively.The median serum CgA and NSE levels were 130.4 ng/ml (95.7-205.7 ng/ml) and 15.2 ng/ml(12.4-18.7 ng/ml) at the time of failure of AA treatment,respectively.There was no significant difference of NED markers between baseline and failure of AA treatment (P =0.243).In logistic univariate analysis,AA treatment and its duration were not independent factors influencing NED(P =0.30;P =0.52).Compared with the NED markers elevation group in the first 6 months of AA treatment and baseline supranormal NED markers group,the NED markers decline group(PSA PFS(17.1 vs.10.4 months,P ＜ 0.001) and rPFS (17.0 vs.10.4 months,P =0.003)) and baseline normal NED markers group(PSA PFS(14.1 vs.9.5 months,P =0.001) and rPFS(16.4 vs.10.5 months,P ＜ 0.001)) has a longer median PSA PFS and rPFS respectively.In multivariate Cox analysis,baseline NED markers level and NED markers variation during the first 6 months of AA treatment remained significant predictors of rPFS(P ＜ 0.05),and PSA-PFS (P ＜ 0.05).Conclusions We found there was heterogeneity in changes of NED markers in different mCRPC patients during AA treatment,and AA might not significantly lead to progression of NED of mCRPC in general.Serial CgA and NSE evaluation might help clinicians guide clinical treatment of mCRPC patients.Serum NED markers elevation during the first 6 months of AA treatment and elevated baseline NED markers levels indicated poor prognosis in mCRPC treated with AA.
