Objective:To explore the clinical manifestations,diagnosis,pathological features and treatment of small-cell carci-noma of the prostate(SCCP).Methods:We conducted a retrospective analysis of the clinical and pathological data of 2 cases of confirmed SCCP treated from November 2017 to March 2018,and reviewed relevant literature.Results:Both the patients had the symptoms of frequent,urgent and difficult urination,with an elevated level of PSA and grades Ⅱ-Ⅲ enlargement of the prostate at palpation.One underwent prostate puncture biopsy and the other received transurethral 1470 laser vaporization resection of the tumor.Postoperative pathology indicated prostate adenocarcinoma accompanied by SCCP in both of the cases.One of them was treated by eto-poside-platinum(EP)chemotherapy and died of systemic multiple organ failure 20 months after diagnosis,while the other underwent endocrine therapy and has lived with tumor up to the present day.Conclusion:The incidence rate of SCCP is low,its malignancy is high,and its prognosis is poor.The average survival of the patient is about 7 to 10 months after diagnosis.Currently there is no effec-tive management of the dissease,except by relying on the experience of the treatment of small-cell lung cancer,with chemotherapy as the main option.

OBJECTIVES: To explore a new method for electroencephalography (EEG) background analysis in neonates with hypoxic-ischemic encephalopathy (HIE) and its relationship with clinical grading and head magnetic resonance imaging (MRI) grading. METHODS: A retrospective analysis was performed for the video electroencephalography (vEEG) and amplitude-integrated electroencephalography (aEEG) monitoring data within 24 hours after birth of neonates diagnosed with HIE from January 2016 to August 2022. All items of EEG background analysis were enrolled into an assessment system and were scored according to severity to obtain the total EEG score. The correlations of total EEG score with total MRI score and total Sarnat score (TSS, used to evaluate clinical gradings) were analyzed by Spearman correlation analysis. The total EEG score was compared among the neonates with different clinical gradings and among the neonates with different head MRI gradings. The receiver operating characteristic (ROC) curve and the area under thecurve (AUC) were used to evaluate the value of total EEG score in diagnosing moderate/severe head MRI abnormalities and clinical moderate/severe HIE, which was then compared with the aEEG grading method. RESULTS: A total of 50 neonates with HIE were included. The total EEG score was positively correlated with the total head MRI score and TSS (r_s=0.840 and 0.611 respectively, P<0.001). There were significant differences in the total EEG score between different clinical grading groups and different head MRI grading groups (P<0.05). The total EEG score and the aEEG grading method had an AUC of 0.936 and 0.617 respectively in judging moderate/severe head MRI abnormalities (P<0.01) and an AUC of 0.887 and 0.796 respectively in judging clinical moderate/severe HIE (P>0.05). The total EEG scores of ≤6 points, 7-13 points, and ≥14 points were defined as mild, moderate, and severe EEG abnormalities respectively, which had the best consistency with clinical grading and head MRI grading (P<0.05). CONCLUSIONS The new EEG background scoring method can quantitatively reflect the severity of brain injury and can be used for the judgment of brain function in neonates with HIE.

Objective To investigate the effect of long non-coding RNA (IncRNA) nuclear-enriched abundant transcript 1 (NEATl) on hypoxia-reoxygenation (H/R) glial astrocyte injury, and to explore whether the mechanism was related to the regulation of micro RNA (miR)-761. Methods Rat cortical astrocytes were cultured to construct a H/R injury model. Astrocytes were divided into control group, model group, model+ small interfering RNA negative control (si-NC) group, model+ si-NEATl group, model+ miR-NC group, model + miR-761 group, model + si-NEATl + anti-miR-NC group, model+si-NEATl+anti-miR-761 group. Expression of NEATl and miR-761 were detected by Real-time PCR. The experiment was repeated 3 times. The content of malonaldefryde (MDA), and the activity of superoxide dismutase (SOD) and catalase (CAT) were detected by kits. Dual luciferase reporter experiment and Real-time PCR were used to analyze the targeting relationship between NEATl and miR-761. The experiment was repeated 3 times. Results Compared with the control group, the cell apoptosis rate and MDA content of the model group increased significantly, SOD and CAT activities decreased significantly, NEATl expression increased significantly, and miR-761 expression decreased significantly (P< 0. 05). Compared with the model+si-NC group, the apoptosis rate and MDA content of the model+si-NEATl group reduced significantly, and SOD and CAT activities increased significantly (P < 0 . 0 5) . Compared with the model + miR-NC group, the apoptosis rate and MDA content of the model + miR-761 group reduced significantly, and SOD and CAT activities increased significantly (P < 0 . 0 5) . MiR-761 was the target gene of N E A T l, and NEATl negatively regulated miR-761 expression. Compared with the model+si-NEATl+anti-miR-NC group, the apoptosis rate and MDA content of the model+siNEAT1+anti-miR-761 group increased significantly, and SOD and CAT activities decreased significantly (P < 0 . 0 5) . Conclusion Interference with NEATl expression can protect astrocytes from H / R injury by up-regulating miR-761.

OBJECTIVE: To investigate the difference of therapeutic effects on children with thalassemia at different age after hematopoietic stem cell transplantation. METHODS: The clinical data of children with thalassemia treated in our hospital were retrospectively analyzed. The children were divided into 2-5 years old group and 6-12 years old group. The success rate of implantation, transplant-related mortality, GVHD incidence, and other transplant-related complications, as well as thalassemia-free survival (TFS) were compared between the two groups. RESULTS: The incidence of GVHD, hemorrhagic cystitis and severe oral mucositis after transplantation in the 2-5 years old group were significantly lower than those in the 6-12 years old group, while there was no statistically significant difference in the TFS between the two groups. CONCLUSION Children in the low age (2-5 years old) group show fewer complications and higher quality of life after transplantation, therefore, stem cell transplantation at 2-5 years old is more conducive to rehabilitation of the children with thalassemia.

OBJECTIVE: To retrospectively analyze the efficacy and safety of ruxolitinib therapy for children with thalassemia after unrelated or haploidentical stem cell transplantation. METHODS: From March 2020 to March 2021, 22 patients received successfully allogeneic hematopoietic stem cell transplantation in the Zhongshan Hospital of Xiamen University, from +30 to 100 days,those patients received ruxolitinib therapy (2.5 mg, twice daily) and all adverse reactions were observed, include aGVHD, cGVHD, CMV and EBV infection. RESULTS: 22 patients underwent allogeneic stem cell transplantation, 5 patients were diagnosed as aGVHD, 3 patients had grade I－II skin GVHD and 2 patients had grade II intestinal GVHD, those patients were cured. All patients were followed up for more than 21 weeks, 4 cases developed cGVHD, including 3 cases of localized liver GVHD and 1 case of pulmonary GVHD, those were relieved after active treatment. 8 patients had elevated EBV copies (>3×10³/ml), and 3 patients had increased CMV copies, the patients recovered after immunosuppressant and antiviral treatment. There was no CMV infection and EBV related post-transplantant lymphoproliferative disorders(PTLD), and no transplant related deaths. CONCLUSION Ruxolitinib can effectively reduce the incidence and severity of GVHD without affecting the hematopoietic recovery, and improve the survival status of thalassemia children after transplantation.

Objective:To investigate the quality of rehabilitation medical service in tertiary general hospitals in Gansu Province. Methods:Stratified sampling was used to sample tertiary general hospitals in Gansu Province for on-site surveys in 2017. A quality evaluation index system was established in the view of medical service providers, including 17 indicators, based on Donabedian model and experts' opinions. Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) and Rank-sum Ratio were applied to make a comprehensive evaluation on the overall service quality of the hospital rehabilitation medical service. Results:A total of 27 tertiary general hospitals were sampled, in 13 cities/prefectures of Gansu Province. For the structure quality, the compliance rate of the business operation area and the number of beds in the rehabilitation medicine department were 77.78% and 51.85% respectively; while the compliance rates of the physicians, therapists and nurses were all less than 50%. For the process and results quality, the compliance rates were all more than 85%. For the overall quality of rehabilitation medical service, five hospitals were classified as Good, located in Lanzhou, Tianshui and Jiayuguan; 18 hospitals were classified as Medium, located in Longnan, Longdong, Lanzhou and surround, Linxia and Hexi regions; four hospitals classified as Poor, located in Lanzhou and Tianshui. Conclusion:The overall quality of rehabilitation services in the tertiary general hospitals of Gansu Province needs to be improved, and the development of rehabilitation services is uneven in various regions. Comprehensive evaluation provides an important reference to promote the rational distribution of rehabilitation medical resources and improve the quality of rehabilitation medical services.

Objective:To evaluate the efficacy and safety of traditional Chinese medicine (TCM) in the treatment of post stroke cognitive impairment (PSCI). Method:Seven databases, including CNKI, WanFang, VIP, CBM, PubMed, The Cochrane library and ClinicalTrials.gov, were electronically searched for relevant randomized controlled trials (RCTs) of TCM in the treatment of PSCI. The Cochrane risk of bias assessment tool was used to evaluate the methodological quality of the included studies, descriptive analysis was carried out on the included studies, and the Meta quantitative analysis was carried out with RevMan 5.3 software. Result:A total of 16 RCTs were included with 1 296 participants, and they were assigned to the intervention group (n=649) and the control group (n=647). The results showed that TCM combined with western medicine group and TCM group were better than western medicine group in improving the scores of Montreal Cognitive Assessment (MoCA), Mini-mental State Examination (MMSE), Barthel Index (BI), Activity of Daily Living (ADL), Chinese stroke scale (CSS) and National Institutes of Health stroke scale (NIHSS) of PSCI patients, and no serious adverse events were observed. Conclusion:TCM has potential advantages in improving the cognitive function of patients with PSCI, and it also has certain efficacy in improving the daily living ability and neurological impairment symptoms, and no serious adverse events have been observed. Due to the low quality of methodology included in the studies, in order to provide reliable basis for clinical decision-making, high-quality of RCTs are still needed to study the efficacy and safety of TCM for PSCI.
