		                        			Objective: To explore the safety and effectiveness of stereotactic body radiation therapy (SBRT) for oligometastases from colorectal cancer (CRC). Methods: This is a prospective, single-arm phase Ⅱ trial. Patients who had histologically proven CRC, 1 to 5 detectable liver or lung metastatic lesions with maximum diameter of any metastases ≤5 cm were eligible. SBRT was delivered to all lesions. The primary endpoint was 3-year local control (LC). The secondary endpoints were treatment-related acute toxicities of grade 3 and above, 1-year and 3-year overall survival (OS) and progression free survival (PFS). Survival analysis was performed using the Kaplan-Meier method and Log rank test. Results: Petients from 2016 to 2019 who were treated in Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College. Forty-eight patients with 60 lesions were enrolled, including 37 liver lesions and 23 lung lesions. Forty-six patients had 1 or 2 lesions, with median diameter of 1.3 cm, the median biologically effective dose (BED(10)) was 100.0 Gy. The median follow-up was 19.5 months for all lesions. Twenty-five lesions developed local failure, the median local progression free survival was 15 months. The 1-year LC, OS and PFS was 70.2% (95% CI, 63.7%~76.7%), 89.0% (95% CI, 84.3%~93.7%) and 40.4% (95%CI, 33.0%~47.8%). The univariate analysis revealed that planning target volume (PTV) and total dose were independent prognostic factors of LC (P<0.05). For liver and lung lesions, the 1-year LC, OS and PFS was 58.7% and 89.4% (P=0.015), 89.3% and 86.5% (P=0.732), 30.5% and 65.6% (P=0.024), respectively. No patients developed acute toxicity of grade 3 and above. Conclusion: SBRT is safe and effective treatment method for oligometastases from CRC under precise respiratory motion management and robust quality assurance.

		                        			Objective: To explore the types and clinical characteristics of chronic rhinosinusitis with nasal polyps (CRSwNP) based on artificial intelligence and whole-slide imaging (WSI), and to explore the consistency of the diagnostic criteria of the Japanese epidemiological survey of refractory eosinophilic chronic rhinosinusitis (JESREC) in Chinese CRSwNP patients. Methods: The data of 136 patients with CRSwNP (101 males and 35 females, aging 14 to 70 years) who underwent endoscopic sinus surgery from 2018 to 2019 in the Department of Otorhinolaryngology Head and Neck Surgery, the Third Affiliated Hospital of Sun Yat-sen University were analysed retrospectively. The preoperative clinical characteristics of patients were collected, such as visual analogue scale (VAS) of nasal symptoms, peripheral blood inflammatory cell count, total immunoglobulin E (IgE), Lund-Kennedy score and Lund-Mackay score. The proportion of inflammatory cells such as eosinophils, lymphocytes, plasma cells and neutrophils were calculated on the WSI of each patient through artificial intelligence chronic rhinosinusitis evaluation platform 2.0 (AICEP 2.0), and the specific type of nasal polyps was then obtained as eosinophilic CRSwNP (eCRSwNP) or non-eosinophilic CRSwNP (non-eCRSwNP). In addition, the JESREC diagnostic criteria was used to classify the nasal polyps, and the classification results were compared with the current gold standard for nasal polyps diagnosis (pathological diagnosis based on WSI). The accuracy, sensitivity and specificity of the diagnostic criteria of JESREC were evaluated. The data were expressed in M (Q1, Q3) and statistically analyzed by SPSS 17.0. Results: There was no significant difference between eCRSwNP and non-eCRSwNP in age distribution, gender, time of onset, total VAS score, Lund-Kennedy score or Lund-Mackay score. However, there was a significant difference in the ratio of nasal polyp inflammatory cells (eosinophils 40.5% (22.8%, 54.7%) vs 2.5% (1.0%, 5.3%), neutrophils 0.3% (0.1%, 0.7%) vs 1.3% (0.5%, 3.6%), lymphocytes 49.9% (39.3%, 65.9%) vs 82.0% (72.8%, 87.5%), plasma cells 5.1% (3.6%, 10.5%) vs 13.0% (7.4%, 16.3%), χ2 value was 9.91, 4.66, 8.28, 5.06, respectively, all P<0.05). In addition, eCRSwNP had a significantly higher level of proportion of allergic symptoms (nasal itching and sneezing), asthma, peripheral blood eosinophil and total IgE (all P<0.05). The overall accuracy, sensitivity and specificity of the JESREC diagnostic criteria was 74.3%, 81.3% and 64.3%, respectively. Conclusions: The eCRSwNP based on artificial intelligence and WSI has significant high level of allergic symptoms, asthma, peripheral blood eosinophils and total IgE, and the percentages of inflammatory cells in nasal polyps are different from that of non-eCRSwNP. The JESREC diagnostic criteria has good consistency in our research.

		                        			Objective:To understand the psychological needs of severe mentally ill persons under closed management during hospitalization.Methods:From March 2017 to March 2018, a total of 81 severe mentally ill persons under closed management in Sichuan Mental Health Center were selected as research objects by the convenience sampling method. A self-designed questionnaire for the psychological needs of severe mentally ill persons was used to investigate the psychological needs of patients such as self-awareness, self-attribution of hospitalization and problems they wish to solve and to analyze the influencing factors of psychological needs of patients.Results:Among the 81 patients, 33.33% (27/81) thought that they were ill. For this hospitalization, 39.51% (32/81) of the patients attributed to their personality and 17.28% (14/81) attributed to emotional problems. Among the psychological needs, 79.01% (64/81) wished to be accompanied and visited by family members, and 62.96% (51/81) required psychological treatment. Among the most wanted problems, 35.80% (29/81) hoped to cure the disease and only 4.94% (4/81) wanted to improve self-confidence. Patients diagnosed with different diseases had statistically significant differences in their needs for family accompany, and visitation ( P<0.05) . Patients of different genders have statistically significant differences in the needs of their own disease-related knowledge ( P<0.05) . There was a statistically significant difference in patients with different educational levels in improving stress coping ability ( P<0.05) . Conclusions:Severe mentally ill persons under closed management during hospitalization have more psychological needs with different genders, educational levels, and different disease diagnosis. Therefore, it is necessary to provide targeted psychological intervention and nursing to promote the recovery of patients as soon as possible.

BACKGROUNDMost patients with epilepsy want to learn as much as possible about the disease, and many have turned to the internet for information. Patients are likely to use information obtained from the internet to control their epilepsy, but little is known about the accuracy of this information. In this survey, we have assessed the feasibility and usability of internet-based interventions for the treatment of epilepsy.
METHODSData were collected from an internet search. Different search terms were used to obtain general information on epilepsy together with information about medication, types of epilepsy, treatment, women's health, and other information. The accuracy of the information was evaluated by a group of experts.
RESULTSA total of 1320 web pages were assessed. The majority were websites related to health. A large number (80.2%) of web pages contained content related to the search term. A significant number of web pages 450/1058 (42.5%) claimed to provide information from a credible source; however, only 206/1058 (19.5%) of the information was accurate and complete; 326/1058 (30.8%) was accurate but incomplete; 328/1058 (31.0%) was correct but nonstandard, and 198/1058 (18.8%) was inaccurate. The authenticity of the information was not significantly different between the two search engines (χ2 = 0.009, P = 0.924). No significant difference was observed in the information obtained from a specialist or nonspecialist source (χ2 = 7.538, P = 0.057). There was also no correlation between the quality of the information and the priority (χ2 = 6.880, P = 0.076).
CONCLUSIONSSearching for information about epilepsy on the internet is convenient, but the information provided is not reliable. Too much information is inaccurate or for advertisement purposes, and it is difficult for patients to find the useful information. Turning to the internet for medical knowledge may be harmful. Physicians should be aware that their patients may search for information on the internet and guide them to safe, reputable websites.

OBJECTIVETo establish an effective testing system for gene diagnosis, carrier detection and prenatal diagnosis for spinal muscular atrophy (SMA).
METHODSTwenty-six patients with SMA were directly tested with PCR-RFLP for exon 7 deletion in the SMN1 gene. Carrier detection was carried out with multi-PCR-DHPLC. Amniotic fluid was taken at the middle stage of gestation from pregnant women who had given birth to affected children.
RESULTSTwenty-five out of 26 patients were diagnosed as having SMN1 gene deletion. Fifty-two of their parents were found to be carriers of exon 7 deletion. Eight of 20 fetuses were diagnosed as having SMN1 gene deletion by PCR-RFLP.
CONCLUSIONPCR-RFLP and multi-PCR-DHPLC techniques can provide rapid diagnosis for exon 7 deletion detection and carrier detection. PCR-RFLP may also be adapted for prenatal gene diagnosis of exon 7 deletion in SMN1 gene.

		                        			This study was purposed to investigate the correlation between the dose infused megakaryocytic precursors (CD34+, CD34+CD61+) and recovery time of platelet count following an allogeneic PBSCT and/or BMT through quantitative detection of CD34+ and its subpopulation in peripheral blood and BM mobilized by G-CSF. 24 patients with various hematologic malignancies received PBSCT/BMT from their HLA matched or unrelated donors and haploidentical siblings in April-December 2007. 20 evaluated patients were divided into 2 groups according to different transplant schemes. HLA matched group received PBSCT regime and haploidentical group received PBSCT combined with BMT. CD34+CD61+ subpopulations in sample from patients receiving PBSCT/BMT were measured by flow cytometry immediately or storage over night. The results showed that the median number of infused CD34+, CD34+CD61+ and CD34-CD61+ cells in haploidentical group were 6.24x10(6)/kg (1.53-20.48), 66.19x10(4)/kg (8.16-493.83), and 34.38x10(6)/kg (14.71-109.16) respectively, in HLA matched group those were 4.88x10(6)/kg (1.00-8.24), 14.16x10(4)/kg (11.63-96.87), and 13.50x10(6)/kg (1.74-35.61), respectively. Median days of ANCs>0.5x10(9)/L and platelets>20x10(9)/L were 18.5 (11.0-29.0) days and 16.5 (9.0-35.0) days in haploidentical group respectively; in HLA matched group those were 14.5 (9.0-24.0) and 10.5 (6.0-37.0) respectively. A significance difference of median days for ANC engraftment presented between two groups (p=0.048). There was no significant difference of time for platelet engraftment between 2 groups. For patients with CD34+ cell dose>2x10(6)/kg there was significant difference of time of platelet engraftment between HLA matched and haploidentical groups (p=0.006). The number of CD34+CD61+ cells infused in 12 haploidentical patients or in 8 HLA matched patients were much better correlated with the time of platelet recovery up to 20x10(9)/L than that of number of CD34+ cells infused in total 20 patients (r=-0.768 and p=0.004 for haploidentical CD34+CD61+ cells, r=-0.747 and p=0.033 for HLA matched CD34+ CD61+ cells, r=-0.449 and p=0.047 for CD34+ cells). There was an inverse correlation between the number of infused CD34+ CD61+ cells and time of platelet engraftment. Therefore, as the number of CD34+ CD61+ cells increased, duration of platelet engraftment (time to reach platelet count of 20x10(9)/L) shortened significantly. It is concluded that the determining the number of megakaryocytic precursor by flow cytometry may predict the platelet reconstitutive capacity of the allogeneic hematopoietic stem cell transplantation, which is in haploidentical PBSCT and in BMT.

OBJECTIVETo establish an effective method of genetic diagnosis on hemophilia A (HA) by detecting the inversion mutation in intron 22 of F8 gene.
METHODSIntron 22 inversion mutation in F8 gene was detected by using long distance-polymerase chain reaction (LD-PCR) and inversion-PCR (I-PCR) in 31 HA patients. The mothers of HA patients with intron 22 inversion mutation were selected to carrier diagnosis and amniotic fluid of the pregnant women with inversion mutation was collected at intermediate stage of gestation, and used to prenatal genetic diagnosis.
RESULTSSeven patients showed F8 gene inversion mutation in thirty-one patients. Three in four mothers of HA patients with intron 22 inversion mutation were diagnosed as carriers. The prenatal diagnosis result indicated that the fetus conceived in the HA-carrier woman was normal individual.
CONCLUSIONThe detection of intron 22 inversion mutation by LD-PCR and I-PCR is time-saving, and can be used in prenatal diagnosis on HA.
