目的 分析神经系统副肿瘤综合征（PNS）的临床特点以提高对该病的早期诊断和治疗效果。方法 回顾性分析惠州市第一人民医院和惠州市中心人民医院神经内科2019年10月—2022年10月收治的21例PNS患者的临床表现、实验室检查结果和治疗效果,并作文献回顾。结果 21例患者中出现了10种副肿瘤综合征,其中经典综合征占比28.6%（6/21）,最多见的是边缘叶脑炎;20例在血液或脑脊液中发现检测到抗神经元抗体,非特征性抗体阳性率最高（12/20）,其中以半定量脑组织切片TBA检测阳性率最高（7/20）;有特征性抗体的8例以抗Yo抗体阳性率最高（6/8）。21例患者均随访至2023年3月,8例发现原发肿瘤,其中4例在神经系统病变之后。69.25%（9/13）的患者使用糖皮质激素治疗和（或）丙种球蛋白治疗有效。结论 21例PNS患者中以非经典综合征占比较多,经典与非经典副肿瘤综合征均应进行肿瘤筛查,未发现肿瘤者应密切随访。非特征性抗体阳性率最高,提示PNS可能仍有许多相关抗体未明确,临床工作中也应对非特征性抗体阳性予以重视。

Objective To analyze the clinical features of paraneoplastic neurological syndrome（PNS）to improve the early diagnosis and treatment of this disease. Methods The clinical manifestations,laboratory results and treatment effects of 21 patients with PNS admitted to Huizhou First People's Hospital and Huizhou Central People's Hospital from October 2019 to October 2022 were retrospectively analyzed,and literature review was performed. Results There were 10 paraneoplastic syndromes in 21 patients,of which classical syndrome accounted for 28.6%（6/21）,the most common was limbic lobe encephalitis．Anti-neuronal antibodies were detected in blood or cerebrospinal fluid in 20 cases,with the highest positive rate of non-characteristic antibodies（12/20）,among which the positive rate of TBA detection by semi-quantitative brain tissue sections was the highest（7/20）;Eight cases with characteristic antibodies had the highest positive rate of anti-Yo antibody（6/8）．All 21 patients have been followed up so far,and 8 cases have found primary tumors,4 of which were after neurological lesions．There was 69.25%（9/13）of patients responded to hormone therapy or（and）gamma globulin therapy. Conclusions Non-classical syndrome accounts for more patients with PNS,and both classical and non-classical paraneoplastic syndromes should be screened for tumors,and those who have not found tumors should be closely followed．The positive rate of non-characteristic antibodies is the highest,indicating that there may still be many related antibodies in PNS that are not clear,and the positive of non-characteristic antibodies should also be paid attention to in clinical work．

Objective To investigate the clinical outcomes of the single blastocyst transfer of day 5 in the women under 35 years old. Methods A retrospective study was conducted to analyze clinical outcomes of women less than 35 years old and experienced embryo transfer in the first frozen-thawed cycles from January 2016 to July 2019 in the Center of Reproductive Medicine of Guangzhou Women and Children's Medical Center. According to the embryo developmental days and transfer blastocyst numbers, all patients were divided into three groups: double high-quality cleavage embryo transfer of day 3 (n=508), single blastocyst transfer of day 5(n=47), double blastocyst transfer of day 5(n=108). The clinical outcomes were compared. Results The clinical pregnancy rate of the double blastocyst transfer of day 5 was higher than the other two groups,and the differences were statistically significant(P＜0.05). However, there was no statistical difference between the single blastocyst transfer of day 5 and the double high-quality cleavage embryo transfer of day 3(P＞0.05). The multiple pregnancy rate of the single blastocyst transfer of day 5 was lower than the other two groups, and the differences were statistically significant (P＜0.001),and that of the double high-quality cleavage embryo transfer of day 3 was even lower than that of the double blastocyst transfer of day 5,and the difference was statistically significant(P＜0.05). The implanting rate of the double high-quality cleavage embryo transfer of day 3 was lower than the other two groups, and the differences were statistically significant (P＜0.05;P＜0.001),but there was no statistical difference between the single blastocyst transfer of day 5 and the double blastocyst transfer of day 5 (P＞0.05). However, the early miscarriage rate and the ectopic pregnancy rate did not exhibit statistical differences (P＞0.05). Conclusion Single blastocyst transfer of day 5 can ensure clinical pregnancy rate and implantation rate while effectively reducing multiple pregnancy in the women undergoing the first frozen-thawed cycles of under 35 years old.

Objective To investigate the clinical features of infantile allergic proctocolitis and its endoscopic lesions and pathological features. Methods A retrospective analysis of 110 cases of infantile allergic proctocolitis admitted to our hospital from January 2016 to December 2018 and its colonoscopy and pathological results, food allergen-specific IgG, blood routine, fecal routine, serum total IgE detection and treatment. Results Among 110 patients with allergic proctocolitis, 67 were male and 43 were female, 98 were < 6 months old; 26 were breastfed exclusively, 19 were fed milk alone, and 65 were mixed feeding. The clinical manifestations were diarrhea, most of children with bloody stools (93 cases), some children with eczema (23 cases), defecation and crying (67 cases), restless sleep (61 cases), vomiting (8 cases), malnutrition (6 cases); blood eosinophils increased in 63 cases,serum total IgE increased in 21 cases. Food allergen-specific IgG test results:103 cases of milk, 62 cases of eggs. Endoscopic lesions involved the descending colon, sigmoid colon, rectum, 76 cases of transverse colon, 47 cases of ascending colon and 18 cases of ileocecal. Most common manifested as herpes-like changes (106 cases), erosion (97 cases), ulcers (13 cases). Histopathology showed 91 cases of intestinal mucosal eosinophil infiltration, 21 cases of cryptitis and crypt hyperplasia, 18 cases of lymphoid follicle formation and 4 cases of superficial ulcer formation. 18 cases were improved after the mother evaded diet. 8 cases were improved by feding with amino acid milk powder for one week, and then breast milk was gradually introduced; 19 cases were improved after switching to deep hydrolysis or amino acid milk powder. 65 cases were improved after switching to deep hydrolysis or amino acid milk powder and simultaneously the mother evaded diet. Conclusion Infantile allergic proctocolitis lack of insufficient specific manifestations, most of the clinical cases are good, only a few are complicated by malnutrition. Milk is the most important allergen. Diarrhea, history of blood in the stool, elevated blood eosinophils, intestinal herpes-like changes, bowel mucosal eosinophil infiltration, are suggesting a high possibility of allergic proctocolitis. Mothers avoiding diet or switching to amino acids or deep hydrolyzed milk powder treatment is also effective, and this is also the standard of diagnosis of proctocolitis.

Objective To retrospectively analyze information and drug susceptibility of 50 cases of Salmonella typhimurium isolated from children with diarrhea in Shantou Central Hospital from 2017 to 2018, and to obtain the characteristics of Salmonella typhimurium infection in Shantou area in the past two years and to guide rational drug use in clinic. Methods Salmonella was isolated from fecal specimens of children with diarrhea. The susceptibility of Salmonella to antimicrobial agents was detected by disk diffusion method. Serological agglutination test was used to determine the serotype of salmonella. Sample data identified as Salmonella typhimurium were recorded and analyzed. Results Among the 50 children with diarrhea, the susceptibility time of Salmonella typhimurium was summer and autumn; the age of 0～1 was susceptible population; fever and diarrhea were common after infection, and hematochezia and vomiting were rare; Salmonella typhimurium had 100% susceptibility to imipenem, tegacycline and ertapenem, 96% and 92.68% to guacillin/tazobactam, cefotaxone/sulbactam. The sensitivity rate of amoxicillin/clavulanic acid was 80.48%. It was 100% resistant to amikacin, cefuroxime axetil, cefuroxime and cefoxitin. It had different sensitivity and resistance to other antibiotics. Conclusion In summer and autumn, children aged 0～1 should strengthen prevention of Salmonella typhimurium infection. If symptoms of fever and diarrhea occur, doctors should consider the direction of Salmonella typhimurium treatment. Salmonella typhimurium is resistant to multi-antibiotics, and rational use of antibiotics in clinic should be based on the results of drug sensitivity.

目的 比较一线伊马替尼疗效欠佳的慢性髓性白血病慢性期(CML-CP)患者,继续伊马替尼原方案或转换为尼洛替尼治疗后的疗效及安全性。方法 收集伊马替尼疗效欠佳的 45 例患者,分为伊马替尼组22例及尼洛替尼转换组23例,22例伊马替尼组患者继续接受原方案伊马替尼治疗,剂量均为400 mg qd,又将尼洛替尼转换组分为早期尼洛替尼转换组7例,晚期尼洛替尼组转换有16例。尼洛替尼转换组的23例患者接受尼洛替尼的剂量均为400 mg,q12h。所有入组患者首诊时测定 Sokal 评分,在治疗过程中随访观察定期监测血液学、细胞遗传学及分子学缓解情况(FISH 和 RQ-PCR),并对患者用药后的基本情况、临床表现及不良反应进行记录。结果 转换尼罗替尼治疗3个月时,早期尼洛替尼转换组中国际标准化 BCR-ABL1融合基因转录本水平(BCR-ABL1^IS)＜10%的患者有 5 例(71.4%),晚期尼洛替尼转换组BCR-ABL1^IS＜10%的患者有6例(37.5%),差异无统计学意义(P＞0.05)。中位观察6(3～12)个月,尼罗替尼组中有17例(73.9%)获得部分细胞遗传学反应,9例(39.1%)患者获得主要分子学反应。伊马替尼组中有9例(40.9%)获得部分细胞遗传学反应,2例(9.1%)患者获得主要分子学反应,尼洛替尼组部分细胞遗传学反应、主要分子学反应患者优于伊马替尼组(P值分别为0.027、0.020)。45例患者中达到完全细胞遗传学反应的患者与未达到完全细胞遗传学反应相比,Sokal 评分偏低(P=0.032)。结论 尼洛替尼可使伊马替尼疗效欠佳的 CML-CP 患者达到更好的疗效,因此需要及时对伊马替尼疗效欠佳的 CML-CP 患者进行评估后及时更换为尼洛替尼等二代酪氨酸激酶抑制剂。

Objective To assess the clinical efficacy and safety of original scheme or switching to nilotinib in patients with chronic myeloid leukemia in chronic phase(CML-CP)with suboptimal response of first-line imatinib. Methods 45 patients with suboptimal response of imatinib were collected and divided into 22 patients who continued to use original scheme and 23 patients who switched to nilotinib therapy. All the 22 patients of imatinib group received imatinib 400 mg once a day. And the 23 patients of nilotinib group were divided into early switch group and late switch group. Early switch group had 7 patients, late switch group had 16 patients. Both early and late switch to nilotinib group were subsequently to nilotinib 400 mg q12h. Sokal scores of all the enrolled patients were measured at the first diagnosis. Hematology, cytogenetics and molecular remission (FISH and RQ-PCR)were monitored, and the patients' basic information, clinical manifestations and adverse reactions were recorded regularly during the treatment. Results After switching to nilotinib for 3 months,there were 5 patients (71.4%)whose BCR-ABL1^IS<10% in the early nilotinib switch group, while 6 patients (37.5%)in the late nilotenib switch group.There was no statistical difference(P>0.05).With a median observation period of 6(3～12)months,there were 17 (73.9%)patients achieved partial cytogenetic response and 9 (39.1%)patients achieved major molecular response in the nilotinib group,there were 9 patients (40.9%)achieved partial cytogenetic response and 2 patients (9.1%)achieved major molecular response in the imatinib group. Patients who achieved partial cytogenetic response and major molecular response in the nilotinib group were more than those in the imatinib group (P values were 0.027 and 0.020, respectively).Sokal scores of 45 patients who had achieved complete cytogenetic response were lower than those who had achieved it (P=0.032). Conclusion Early switch to nitotinib is feasible and effective to patients who didn't have optimal response to imatinib. It is necessary to assess patients regularly in order to have the proper timing switching patients to nilotinib therapy.
