目的 分析布鲁氏菌病的临床表现以及实验室检查结果中的关键特征，系统总结布鲁氏菌病的诊断流程和治疗策略。方法 选择2013年11月—2023年11月在延边大学附属医院通过血清虎红平板凝集试验（RBT）及试管凝集试验（SAT）检测技术确诊的70名布鲁氏菌病住院病例，对患者的流行病学资料、临床表现特征以及常规实验室检查结果进行回顾性分析，进而总结临床特点。结果 70例布鲁氏菌病患者中，男性占84.29%，中位年龄45岁（IQR 35~58岁）；91.43%具有牛/羊接触史。急性期占92.86%，主要症状为发热（100%）、多汗（88.57%）、关节痛（84.29%）及肝脾肿大（55.71%），90%为不规则热型。误诊率27.14%，多误诊为败血症或骨关节疾病。联合抗菌药物治疗（利福平+多西环素）有效。结论 延边州布鲁氏菌病非典型症状（如不规则热型）增加导致误诊率高。流行病学史（牛/羊接触史）是诊断关键。需强化对有牛羊接触史人群的防护意识及措施，提高临床对接触史线索和不规则热型等非典型表现的识别能力，规范治疗并控制传染源以遏制疫情。
Objective To analyze the clinical manifestations of brucellosis and the key characteristics in laboratory testing，and systematically summarize the diagnostic process and treatment strategies of brucellosis．Methods The 70 patients with brucellosis diagnosed via rose bengal test（RBT）and standard agglutination test（SAT） were at Yanbian University AffiliatedHospital from November 2013 to November 2023．This study conducted a retrospective analysis of the epidemiological data，clinical manifestations and routine laboratory pathological examination data of these patients，and the characteristics of clinical changes were summarized．Results Among the 70 patients with brucellosis，84.29% were male，with a median age of 45（IQR 35-58）；91.43% patients had a history of cattle/sheep exposure．The acute phase accounted for 92.86%，and the main symptoms were fever（100%），sweating（88.57%），arthragia（84.29%），hepatosplenomegaly（55.71%），and 90% were irregular fever．The misdiagnosis rate was 27.14%，and most of them were misdiagnosed as sepsis or osteoarthritis．Combined treatment with antibiotics（rifampin + doxycycline）was effective．Conclusions The increase in atypical symptoms（such as irregular heat type）leads to a high misdiagnosis rate．Epidemiological history（cattle/sheep contact）is the key to diagnosis．It is necessary to strengthen occupational protection and atypical case identification，standardize treatment and control the source of infection to curb the epidemic．
目的 分析广州番禺地区鹦鹉热衣原体肺炎患者临床表现、实验室及胸部CT特征、并发症以及治疗方案，为其临床诊治提供参考。方法 回顾性分析2022年1月—2024年7月在广州市番禺区何贤纪念医院通过二代测序技术确诊的10例鹦鹉热感染患者的临床资料。结果 5例（5/10）患者有明确的鸟类或禽类接触史，8例（8/10）患者以发热为首发症状，发热（10/10）、咳嗽、咳痰（10/10）、呼吸困难（7/10）、相对缓脉（8/10）是主要临床表现。患者白细胞计数通常正常或轻微升高；多数患者存在有不同程度的电解质紊乱（10/10）及肝功能损伤（8/10）、乳酸脱氢酶升高（8/10），白蛋白显著降低（8/10）和C反应蛋白显著升高（10/10）。最常见的胸部CT异常为多肺叶受累的斑片状或片状实变，而重症患者多合并双侧胸腔积液。大多数患者经四环素或喹诺酮类单用，或者四环素联用β-内酰胺类抗菌药物治疗，预后良好。结论 有鸟类或禽类接触史、以发热为首发或主要症状、存在相对缓脉、白细胞计数升高不明显等临床特征可有助于区分鹦鹉热衣原体肺炎与其他传统细菌性肺炎，但这并不能确诊。二代测序技术是确诊鹦鹉热衣原体感染的很好方法，可以缩短诊断延误时间并改善患者预后。
Objective To describe the clinical，laboratory and chest CT characteristics as well as the complications and treatments of Chlamydia psittaci pneumonia patients in Panyu district of Guangzhou，to provide reference for clinical diagnosis and treatment．Methods A retrospective study was conducted on the clinical characteristics of Chlamydia psittaci pneumonia patients who were diagnosed by next-generation sequencing in Panyu Hexian Memorial Hospital of Guangzhou form January 2022 to July 2024．Results Half patients had a definite history of bird or poultry exposure．Fever（100%），cough，sputum（100%），dyspnea（70%），relative bradycardia（80%）were the main clinical presentation．The total white cell counts were usually normal or slightly increased．Most patients had electrolyte disturbance（100%），liver function impairment（80%），lactic dehydrogenase increased（80%），albumin decreased（80%）and C reactive protein increased remarkably（100%）．The most common chest CT abnormality was patchy or flaky hyper densities and consolidation，bilateral pleural effusion was common in severe patients．All patient exhibited good recovery after being treated with tetracycline or quinolone alone，or tetracycline in combination with other antibiotics．Conclusions These characteristics may help distinguish Chlamydia psittaci pneumonia from other traditional bacterial pneumonia，but they are not definitive．Next-generation sequencing may be a promising approach to confirm Chlamydia psittaciinfection，which can shorten the diagnostic delay time and improve the prognosis of patients．

Objective To investigate and analyze the clinical features of children with colorectal polyps and the efficacy of laparoscopic surgery combined with colonoscopy. Methods A total of 98 children with colorectal polyps diagnosed and treated in our hospital from February 2019 to October 2021 were selected as subjects of this study. The clinical characteristics of all children were recorded,and they were divided into the laparoscopic group(laparoscopic surgery combined with colonoscopy,n=40)and the colonoscopy group(colonoscopy,n=58)according to the differences in surgical methods. The therapeutic effect,complication rate,VAS pain score,polyp recurrence and reoperation rate of different surgical methods were compared. Results Among the 98 children,the polyps of 44 cases were in rectum,38 cases in transverse rectum and 16 cases in other sites. The maximum diameter of polyp was(1. 65±0. 24)cm. Polyps were solitary in 83 cases and multiple in 15 cases. The perioperative indexes in the laparoscopic group were significantly improved compared with those in the colonoscopy group(P<0. 05). The incidence of postoperative complications such as infection,bleeding,intestinal perforation and intestinal obstruction was 5. 00% in the laparoscopy group,which was significantly lower than 17. 24% in the colonoscopy group(P<0. 05). The total effective rate of laparoscopic group was 97. 50% one month after operation,which was significantly higher than that of colonoscopy group(82. 76%,P<0. 05). The VAS pain score of the laparoscopic surgery group was significantly lower than that of the colonoscopy group at 1,3 and 7 days after surgery(P<0. 05). After 1 year of follow-up,the combined polyp recurrence rate and reoperation rate were 5. 00% and 2. 50%,which were significantly reduced compared with 18. 97% and 13. 79% in colonoscopy group(P<0. 05). Conclusions The main sites of colorectal polyps in children are rectum and transverse rectum,and most of them are solitary. Laparoscopic and colonoscopic surgery for colorectal polyps in children can promote the recovery of children,improve the overall treatment effect of patients,relieve the pain of children,reduce the occurrence of complications,and reduce the recurrence rate and reoperation rate of follow-up polyps in children.

Objective To explore the epidemiological characteristics, onset characteristics, pathogenic mechanism of 2019-nCoV infection in children, and its control and prevention in Guangzhou. Methods From January 20, 2020 to February 29, 2020, a retrospective analysis was carried out on 129 suspected cases of 2019-nCoV infection admitted to the isolation ward of the only medical unit designated for children in Guangzhou. The epidemiology, disease characteristics, clinical characteristics, laboratory examination, outcome and follow-up were summarized and analyzed. Results There were 79 males and 50 females, with a minimum age of 1 month and a maximum age of 13 years. Anong them, 51 cases (39.5%) had a history of tourism or residence in the epidemic area of Wuhan, 20 cases (15.5%) had a history of contact with people with respiratory symptoms from the epidemic area, 17 cases (13.1%) with a confirmed case in the surrounding area or community, 3 cases (2.3%) had a history of contact with a confirmed patient (2 of them were family clustering cases), 38 cases (29.5%) were clinically suspected cases. Clinical symptoms: 121 cases with fever (93.8%), 92 cases with coughing (71.3%), 50 cases with runny nose (38.8%), 32 cases with diarrhea, vomiting or abdominal pain (24.8%). In 102 cases (79.0%), white blood cells were decreased or normal, 103 cases (79.8%) with CRP＜20 mg/L, and 57 cases (44.2%) showed focal infection on chest X-ray or CT scan. Etiological examination: only one case (0.78%) of the family confirmed cases had positive anal swab result, but the throat swab results were negative all the time. The anal swab and throat swab results of other patients and the throat swab results of their accompanying family members were negative. Other pathogens were detected in 61 cases (47.3%), including 14 RSV positive cases, 9 influenza A positive cases, 8 human metapneumovirus positive cases, 6 enterovirus positive cases, 6 influenza B positive cases, 6 Mycoplasma pneumoniae positive cases, 4 parainfluenza virus type 1 positive cases, 1 parainfluenza virus type 3 positive cases, 2 human bocavirus positive cases, 3 adenovirus positive cases, 1 Klebsiella pneumoniae positive cases, 1 Human Staphylococcus positive case, and 1 case with parainfluenza virus type 1 and human bocavirus. The only confirmed patient was followed up while multiple pharyngeal swab results were negative, and the positive anal swab results lasted for 19 days before turning negative and remained asymptomatic. Other patients were followed up on the 3rd, 7th and 14th day after discharge, and no abnormal findings were found. Conclusion Screening/suspected cases of 2019-nCoV infection in children were mostly clinically manifested as respiratory or gastrointestinal symptoms. The diagnosis rate of nucleic acids was extremely low, and there was a possibility of missed diagnosis. Nearly 50% of cases could find other relevant pathogens excluding the 2019-nCoV. The positive rate of anal swab results was higher than that of pharyngeal swab.
目的 分析区级医院甲型流行性感冒患者的临床特征,为基层医院甲型流感的早期诊断及防控工作提供科学依据。方法 对2019年12月广州市番禺区中心医院发热门诊就诊的具有流感样症状的发热患者共628例,进行咽拭子甲型流感病毒核酸检测,收集患者临床资料,包括性别、年龄、体温、症状、血常规,根据核酸检测结果分为阴性组及阳性组,2组结果进行比较。结果 甲型流感病毒核酸检测阳性患者共116例,阳性率为18.5%。阳性组发病年龄以14～19岁所占比例最大,共91例(78.4%)。阳性组平均年龄小于阴性组(P＜0.05)。阳性组发病体温以38.1～39 ℃所占比例最大,共47例(46.5%)。阳性者平均体温高于阴性组(P＜0.01)。症状方面,阳性组仅鼻塞流涕比例较阴性组高(P＜0.05)。阳性组白细胞计数、中性粒细胞绝对值、淋巴细胞绝对值、淋巴细胞百分比均低于阴性组(P＜0.01)。结论 2019年冬季甲型流感患者以青少年为主,单纯症状较难区分甲型流感及普通感冒,需结合血常规特别是白细胞计数、中性粒细胞绝对值、淋巴细胞绝对值的降低进行分析。
Objective The clinical characteristics of patients with influenza A in district hospital were analyzed to provide scientific basis for early diagnosis, prevention and control of influenza A in primary hospital. Methods A total of 628 patients with influenza-like symptoms from Guangzhou Panyu Central Hospital in December 2019 were enrolled, and the clinical data was collected, including gender, age, body temperature, symptoms, and blood test results. According to the result of influenza A nucleic acid detection, patients were divided into negative group and positive group, and the clinical data of these two groups were compared. Results A total of 116 patients were positive in influenza A virus nucleic acid detection, which positive rate was 18.5%. In the positive group, patients aged 14-19 accounted for the largest proportion, with 91 patients (78.4%). The mean age of the positive group was significantly lower than that of the negative group (P＜0.05). Body temperature ranged from 38.1 to 39 ℃ accounted for the largest proportion in the positive group, with 47 patients (46.5%). The mean body temperature of the positive group was significantly higher than that of the negative group (P＜0.01). In terms of symptoms, only the proportion of nasal congestion in positive group was higher than that in negative group (P＜0.05). In terms of blood test results, WBC count, neutrophil absolute value, lymphocyte absolute value and lymphocyte percentage in the positive group were significantly lower than those in the negative group (P＜0.01). Conclusions The majority of patients with influenza A in the winter of 2019 were teenagers, and it was difficult to distinguish influenza A from the common cold only by symptoms. The differential diagnosis should be carried out in combination with the blood routine analysis, especially the decrease in the white blood cell count, the absolute value of neutrophil and the absolute value of lymphocytes.
