Objective:To analyze the clinical characteristics of patients with acute glyphosate herbicide poisoning and the differences in the severity of poisoning.Methods:A retrospective analysis was performed on patients with acute glyphosate herbicide poisoning admitted to the First Affiliated Hospital of Zhengzhou University from January 2014 to December 2020. The general information, exposure time, poisoning dose, poisoning cause, poisoning route, clinical manifestations, laboratory examination results during hospitalization, treatment measures, hospital stays and prognosis of the patients were collected. The patients were graded according to the poisoning severity scoring standard of Chinese Expert Consensus on Diagnosis and Treatment of Acute Poisoning in 2016. The highest severity score during hospitalization was used as the final grade. According to the final grade, asymptomatic and mild patients were included in the mild group, and moderate, severe and death patients were included in the severe group. The independent sample T test or Mann-Whitney U test was used for measurement data, and χ2 test or Fisher's exact test was used for counting data. The differences of general data and clinical data between the two groups were compared. Results:According to the inclusion and exclusion criteria, 83 patients with acute glyphosate herbicide poisoning were selected as the study subjects. All patients survived, mainly mild poisoning (56.6%), with a male to female ratio of 33∶50, and an average age of 39 years. The number of poisoning cases increased yearly (the highest in 2019), and most cases occurred in spring and summer. The main cause of poisoning was suicide (71.1%), direct oral administration (83.1%) was the primary route of poisoning, and the dominating clinical manifestations were digestive symptoms (71.1%). Laboratory tests showed increased white blood cell count (WBC), neutrophil percentage (NEUT %) and D-dimer, and decreased hemoglobin and potassium. Compared with the mild group, patients in the severe group were older [(51±17) years vs. (35±19) years], had a higher proportion of suicide and direct oral administration, a longer hospital stay [8.0 (4.8, 12.0) d vs. 3.0 (2.0, 5.5) d], a higher dose of poisoning [200.0 (50.0, 200.0) mL vs. 30.0 (11.3, 57.5) mL], and higher NEUT % within 24 h of admission [(83.4±10.4) vs. (73.2±12.8)]. The increase of WBC, NEUT %, aspartate aminotransferase, prothrombin time, D-dimer and the decrease of serum potassium were more common in the severe group than the mild group, with statistical significance (all P<0.05). Conclusions:The number of patients with acute glyphosate herbicide poisoning is increasing yearly. Generally, the condition is mild and the prognosis is satisfying. The severity is more serious in the middle-aged and elderly patients andthose with direct oral administration, high toxic dose, and high NEUT % within 24 h of admission. Severe poisoning is more likely to cause changes in laboratory indicators.

Objective:To explore the current situation of the demand for home care services for the elderly in communities in Jiangsu Province, and to analyze its influencing factors.Methods:From May to August 2020, convenience sampling was used to select 592 community elderly people in Jiangsu Province for a survey. The survey tools included the General Information Questionnaire and Home Care Service Demands Questionnaire.Results:A total of 588 valid questionnaires were recovered, with a valid recovery rate of 99.32%. The demands of the elderly in the community for home care services from high to low were medical care needs (87.07%) , life care needs (68.37%) , spiritual comfort needs (58.16%) , cultural and leisure needs (34.18%) , policy and regulation needs (31.63%) . Logistic regression analysis showed that age, gender, region, type of chronic disease, monthly income and payment method of medical expenses were the main influencing factors of the demand for home care services ( P<0.05) . Conclusions:The elderly in the community have real needs for home care services. It is recommended to establish a diversified, multi-path and layered service system for the needs of the elderly, and strive to improve the effectiveness and efficiency of home elderly care services.

Objective:To investigate the value of paraffin-embedded section of cell block in the diagnosis of lung adenocarcinoma in bloody pleural effusion.Methods:The data of 60 patients with lung adenocarcinoma diagnosed by bloody pleural effusion and confirmed by pathological biopsy in the First Affiliated Hospital of Xi'an Jiaotong University from June 2018 to June 2019 were retrospectively analyzed. Cell smears and paraffin-embedded sections of cell blocks using removed red blood cells sedim entation method were used to make cytological examination in bloody pleural effusion. The expressions of carcinoembryonic antigen (CEA), cytokeratin 7 (CK7), NapsinA, thyroid transcription factor 1 (TTF-1), cytokeratin 5/6 (CK5/6), calretinin, P63 and P40 in the specimens were detected by using immunohistochemistry. The results of histopathological examination were used as the gold standard, and the diagnostic values of cell block paraffin-embedded sections and cell smears for lung adenocarcinoma in bloody pleural effusion were evaluated and compared.Results:The cell block sections had a clear background, clear and easy to distinguish cell morphology, and can be made into permanent specimens. The bloody pleural effusion cell smears results of 60 cases of lung adenocarcinoma showed that 21 cases were diagnosed as atypical cells, 39 cases were diagnosed as adenocarcinoma, and the coincidence rate with the diagnosis of adenocarcinoma by histopathological examination results was 65% (39/60); the immunohistochemistry results of cell block paraffin-embedded sections of bloody pleural effusion showed that CK7, NapsinA, TTF-1 and CEA were positive, and P40, P63, CK5/6 and calretinin were negative, all 60 cases were diagnosed as adenocarcinoma according to the results, and the coincidence rate with the diagnosis of adenocarcinoma by histopathological examination results was 100% (60/60), which was significantly higher than that of cytological smears ( χ2 = 23.088, P < 0.01). Conclusions:The technique of paraffin-embedded section of cell block using removed red blood cells sedim entation method has a high diagnostic rate for lung adenocarcinoma in bloody pleural effusion, and it has a high coincidence rate with histopathological diagnosis. It can improve the accuracy of diagnosis of lung adenocarcinoma in bloody pleural effusion, and it also has a good reference value for cytological typing.

Objective:To investigate the clinical features of patients with anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis misdiagnosed as mental disorder, improve the early diagnosis rate and reduce misdiagnosis.Methods:The clinical data of patients with anti-NMDA receptor encephalitis diagnosed at the First Affiliated Hospital of Zhengzhou University from 2012 to 2018 were collected. Patients misdiagnosed as mental disorders were screened out. Their psychiatric symptom characteristics, disease course characteristics, imaging and laboratory findings, treatment and prognosis were retrospectively analyzed.Results:A total of 121 cases of anti-NMDA receptor encephalitis were collected, and 43 cases of mental disorders were screened out. Sixteen of the 43 patients (37.2%) had prodromal symptoms, and all the patients had psychiatric behavioral abnormalities (100%), including 32 cases (74.4%) of seizures, 13 cases (30.2%) of decreased level of consciousness, 21 cases (48.8%) of involuntary movements, 15 cases (34.9%) of decreased memory, 8 cases (18.6%) of speech dysfunction, and 8 cases (18.6%) of other neurological symptoms (central hyperventilation, autonomic dysfunction). Memory loss was observed in 15 cases (34.9%), speech dysfunction in 8 cases (18.6%), other neurological symptoms (central hypoventilation, autonomic dysfunction) in 8 cases (18.6%), and various symptoms may appear simultaneously or successively in the same patient. Thirty-eight cases had complete resolution of symptoms or only minor physical impairment, and 5 cases had recurrent admissions with mental abnormalities and seizures. The recurrence rate accounted for 11.6% (5/43).Conclusions:The clinical manifestations of anti-NMDA receptor encephalitis are complex and varied. Most of them have mental behavior abnormalities as the first symptom, which is easily misdiagnosed as mental disorder and delayed treatment will lead to prolonged disease course and poor prognosis.

Turnner syndrome is a common sex chromosome disorder. We reported a rare case with Turnner syndrome caused by abnormal number and structure of sex chromosomes. Hereby fluorescence in situ hybridization (FISH) and copy number variation by whole genome low depth sequencing (CNV-seq) were used to clarify the abnormal chromosome. This study provides a diagnostic strategy for clinicians and genetic researchers.

Objective:To investigate the neonatal outcomes and prognosis of fetuses who were prenatally diagnosed with intraventricular hemorrhage(IVH) to provide evidence for clinical consultation and management.Methods:Clinical data of fetal IVH cases ( n=89) diagnosed by fetal neurosonogram (NSG) in Peking University First Hospital from January 2012 to April 2020 were retrospectively collected, and neonatal outcomes were analyzed, involving fetuses with different grades of IVH and coexisting abnormalities. These patients were followed up for more than three months after birth. Two child development screening systems, Ages & Stages Questionnaires (Third Edition) (ASQ-3) and Ages & Stages Questionnaires: Social-Emotional (ASQ-SE), were used to assess the development of the patients from several aspects including physical growth, oral communication, motor ability and social emotions. Descriptive statistical analysis was used in this study. Results:(1) A total of 89 fetuses were enrolled and 66.3% (59/89) of them underwent fetal cranial MRI examination after ultrasound diagnosis. Among these 59 cases, 32(54.2%) had the same results with fetal NSG; 20(33.9%) with the diagnosis of remote ventricular cystic hemorrhage by fetal NSG, but misdiagnosed by MRI, were all confirmed by neonatal craniocerebral ultrasound; 7(11.9%) were lost to follow-up or terminated. In addition to IVH that was consistent with the ultrasound diagnosis, MRI also found three cases of cortical malformation, three cases of subdural hemorrhage and two cases of cerebral parenchymal hemorrhage. (2) Among the 89 cases, 37 (41.6%) underwent neonatal craniocerebral ultrasound examination after birth showing small amount of remote IVH, which was consistent with previous fetal NSG diagnosis. (3) There were 38 cases complicated by lateral ventricular widening (three lost to follow-up, 18 were terminated , one died in uterus, 15 with good and one with poor outcome), 10 cases by severe IVH sequelae (one lost to follow-up and nine were terminated) and 10 by craniocerebral malformation (one lost to follow-up, eight were terminated and one with poor neonatal prognosis). Two cases with extracranial malformation (ureteropelvic junction obstruction) were healthy after birth. (4) There were 29, 30, 16 and 14 cases of gradeⅠ,Ⅱ,Ⅲ andⅣ of fetal IVH, respectively. Among all cases, 12 were lost to follow-up; three died in uterus (all with gradeⅣ IVH); 31 were terminated and 43 were born and followed up. During the follow-up of the 43 cases, two (one grade Ⅰ case with corpus callosum dysplasia and one grade Ⅲ case with fetal cytomegalovirus infection) had poor prognosis, while the other 41 (one gradeⅢ, 17 gradeⅡ and 23 gradeⅠcases) showed no severe abnormalities.Conclusions:Fetal NSG is the first choice in screening fetal IVH and MRI can be a valuable aid. The neonatal prognosis may be associated with the grade of hemorrhage and coexisting abnormalities. Fetuses with isolated grade Ⅰ or Ⅱ IVH usually have a relatively good prognosis.

Observation indicators: (1) clinical charac-teristics of cirrhotic portal hypertension patients; (2) overall prevention and treatment of EVB in cirrhotic portal hypertension patients; (3) prevention and treatment of EVB in cirrhotic portal hypertension patients from different grade hospitals. Measurement data with normal distribution were represented as Mean± SD. Count data were described as absolute numbers, and comparison between groups was analyzed using the chi-square test. Results:(1) Clinical characteristics of cirrhotic portal hypertension patients: of 820 cirrhotic portal hypertension patients, 271 cases were in compensated stage and 549 cases were in decompensated stage. Of the 271 cases in compensated stage, there were 183 maels and 88 females, aged (53±12)years. There were 185 Han people, 85 Hui people and 1 case of other ethic group. The etiological data of liver cirrhosis showed 211 cases of viral hepatitis B, 4 cases of alcoholic liver disease, 8 cases of viral hepatitis C, and 48 cases of other etiology. There were 235 cases of Child-Pugh grade A and 36 cases lack of data. Of the 549 cases in decompensated stage, there were 355 males and 194 females, aged (57±14) years. There were 373 Han people, 174 Hui people and 2 cases of other ethic group. The etiological data of liver cirrhosis showed 392 cases of viral hepatitis B, 33 cases of alcoholic liver disease, 10 cases of viral hepatitis C, and 114 cases of other etiology. There were 80 cases of Child-Pugh grade A, 289 cases of grade B, 170 cases of grade C and 10 cases lack of data. (2) Overall prevention and treatment of EVB in cirrhotic portal hypertension patients: of 271 patients in compensated stage, 38 cases received non-selective β-blocker (NSBB) therapy, 16 cases received endoscopic treatment, 6 cases received interventional therapy. Of 549 patients in decompensated stage, 68 cases received NSBB therapy, 46 cases received endoscopic treatment, 28 cases received interventional therapy. (3) Prevention and treatment of EVB in cirrhotic portal hypertension patients from different grade hospitals: of 271 patients in compensated stage, 181 cases came from tertiary hospitals, of which 28 cases received NSBB therapy, 15 cases received endoscopic treatment, 6 cases received interventional therapy. Ninety cases came from secondary hospitals, of which 10 cases received NSBB therapy, 1 cases received endoscopic treatment. There was no significant difference in NSBB for prevention of EVB between tertiary and secondary hospitals ( χ2=0.947, P>0.05), while there was a significant difference in endoscopic treatment for prevention of EVB between tertiary and secondary hospitals ( χ2=5.572, P<0.05). Of 549 patients in decompensated stage, 309 cases came from tertiary hospitals, of which 22 cases received NSBB therapy, 29 cases received endoscopic treatment, 22 cases received interventional therapy. Two hundreds and fourty cases came from secondary hospitals, of which 46 cases received NSBB therapy, 17 cases received endoscopic treatment, 6 cases received interven-tional therapy. There were significant differences in NSBB and interventional therapy for prevention of EVB between tertiary and secondary hospitals ( χ2=18.065, 5.956, P<0.05). Conclusions:The proportion of receiving EUB prevention in cirrhotic portal hypertension in Ningxia is relatively low. For patients with compensated liver cirrhosis, the proportion of NSBB therapy and endoscopic treatment in the secondary hospitals was lower than that in tertiary hospitals. For patients with decompensated liver cirrhosis, the proportion of interventional treatment in secondary hospitals is lower than that of tertiary hospitals, but the proportion of NSBB in secondary hospitals taking is higher than that of tertiary hospitals.

Objective:To investigate the recovery of patients with acute thallium poisoning after 9 years.Methods:A group of 14 patients with familial thallium poisoning who were admitted to our hospital in 2010 were followed up for 9 years.Results:Among the 14 patients with acute thallium poisoning, one patient died on the 14th day after poisoning, and all the other survivors were followed up 9 years later. The general condition of all the patients was significantly better than that of poisoning 9 years ago. The alopecia of all cases disappeared, the newborn hair grew normally, without gastrointestinal symptoms, numbness, pain in the limbs and mental symptoms. All the patients returned to normal intelligence and physical strength and had a normal life. One patient (No. 5) gave birth to 2 children successively after discharge. The first child was 6 years old and the second child was 2 years old. Both growth and intelligence were not different from those of the same age. Currently, the third pregnancy was more than 7 months. No.6 and No.10 patients were poisoned in their teenage and were currently all studying in university. No.6 patient suffered from Hashimoto's thyroiditis 7 years after poisoning, and he has been taking thiamazole tablets for two years. Poisoned infants, No.7, 8 ,11 and 12, were school-age children with normal growth, mental development and excellent academic performance. Among the 13 surviving patients, blood and urine samples from No. 1, No. 3, and No. 4 patients were collected, and no thallium concentration was detected, and biochemical examina-tion and neurological examination were all normal.Conclusions:Patients with acute thallium poisoning have a favorable prognosis according to the follow-up after 9 years. All patients have no obvious sequelae and have normal labor ability. Young women have normal fertility, and children have normal growth and mental development.

Objective:To investigate therole of serum amylase elevation in the evaluation of diabetic ketoacidosis (DKA) patients and the related factors affecting serum amylase (AMS) levels in patients with diabetic ketoacidosis.Methods:A total of 249 patients with DKA who were admitted to the First Affiliated Hospital of Zhengzhou University from November 2011 to August 2018 were selected for this retrospective study. The patients were divided into the normal group ( n=176) and the elevated group ( n=73) according to the AMS level measured by fasting venous blood samples. The enumeration data such as sex, type of DM, diabetic vascular complications, number of deaths, number of ICU monitoring, and number of acute pancreatitis (AP) after discharge were analyzed by chi-square test or Fisher test, and the measurement data such as age, pH, HbA1c, CO 2CP, Ca 2+, BUN, and Scr were analyzed by independent sample t test to compare the difference between the two groups. Results:The intensive care unit (ICU) monitoring rate was 50.7%, the median length of stay in ICU was 4 days, the median length of hospital stay was 14 days, and the median treatment cost was 28 000 yuan, which were higher in the elevated group than those in the normal group ( P<0.05). There were no significant differences in mortality, AP during hospitalization, and the probability of AP after discharge between the elevated group and the normal group ( P>0.05). The duration of diabetes, the number of previous DKA, the incidence of diabetic vascular complications, HbA1c, pH, BUN, and Scr in the elevated group were all higher than those in the normal group ( P<0.01 or P<0.05). Conclusions:DKA patients with elevated AMS are more likely to be admitted to ICU, and the length of stay in ICU, total length of hospital stay and total cost of treatment are all increased. Where as the overall mortality rate during hospitalization and the likelihood of AP after discharge are not increased.

Objective:To study the efficacy and safety of CT guided percutaneous transhepatic microwave ablation (PTPMWA) for primary liver cancer (PLC) in liver segment 9.Methods:A retrospective study was conducted on PLC patients between October 2013 and March 2019 at Dongguan People’s Hospital, Southern Medical University. Of 41 patients who entered into the study, there were 36 males and 5 females, with an average age of 59.1 years. These patients were diagnosed to have PLC in segment 9. The surgical related data and follow-up results were collected and analyzed.Results:All patients enrolled in the study completed the treatment procedure. CT scan was performed immediately after ablation which showed that the tumor areas to be completely covered by ablation. The duration of operation ranged from 45 to 260 (mean 91) min. The amount of bleeding during treatment was 1.0 to 5.0 (mean 1.4) ml. The complete response rate was 97.6% (40 patients) and the partial response rate was 2.4% (1 patient). The cumulative survival rates at 1, 2, 3, 4 and 5 years were 95.1%, 85.4%, 75.3%, 45.2% and 45.2%, respectively. Only 4 patients (9.8%) developed recurrence after treatment. The timings of recurrence were 1, 6, 13 and 67 months after treatment, respectively. The recurrent lesions were ablated again and complete response was obtained in all patients. There were no serious problems related to complications from ablation. The rate of postoperative complication was 7.3% (3 patients).Conclusion:PTPMWA is a novel treatment for patients with PLC in liver segment 9, the advantages of this treatment include good safety, high efficacy, low complications and local recurrence. The treatment is worthy of further future studies.
